[0013] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to FIG. 1 to FIG. 10.

[0014] An air conditioner (hereinafter, with a cabinet air conditioner as an example) includes an indoor unit and an outdoor unit which are connected by a pipe to transport a refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve and the indoor heat exchanger which are connected in sequence form a refrigerant loop, and the refrigerant circularly flows in the refrigerant loop, and exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger respectively, so as to realize a cooling mode or a heating mode of the cabinet air conditioner.

[0015] The compressor is configured to compress the refrigerant, so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0016] The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported in the outdoor heat exchanger. For example, the outdoor heat exchanger works as a condenser in the cooling mode of the cabinet air conditioner, so that the refrigerant compressed by the compressor radiates heat to the outdoor air by the outdoor heat exchanger to be condensed. The outdoor heat exchanger works as an evaporator in the heating mode of the cabinet air conditioner, so that the decompressed refrigerant absorbs heat of the outdoor air by the outdoor heat exchanger to be evaporated.

[0017] In some embodiments of the present disclosure, the outdoor heat exchanger further includes heat exchange fins to increase a contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving a heat exchange efficiency of the outdoor air and the refrigerant.

[0018] The outdoor fan is configured to suck the outdoor air into the outdoor unit through an outdoor air inlet of the outdoor unit, and deliver the outdoor air after heat exchange by the outdoor heat exchanger out through an outdoor air outlet of the outdoor unit. The outdoor fan supplies power to flowing of the outdoor air.

[0019] The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger, and a pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger is adjusted by an opening degree of the expansion valve, so as to adjust a flow rate of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger affect heat exchange performances of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve may be an electronic valve, and the opening degree of the expansion valve is adjustable to control a flow rate and pressure of the refrigerant flowing through the expansion valve.

[0020] The four-way valve is connected into the refrigerant loop, and the four-way valve is configured to switch a flow direction of the refrigerant in the refrigerant loop, so that the cabinet air conditioner implements the cooling mode or the heating mode.

[0021] The indoor heat exchanger is configured to exchange heat between indoor air and the refrigerant transported in the indoor heat exchanger. For example, the indoor heat exchanger works as an evaporator in the cooling mode of the cabinet air conditioner, so that the refrigerant dissipating heat through the outdoor heat exchanger absorbs heat of the indoor air by the indoor heat exchanger to be evaporated. The indoor heat exchanger works as a condenser in the heating mode of the cabinet air conditioner, so that the refrigerant absorbing heat through the outdoor heat exchanger dissipates heat to the indoor air by the indoor heat exchanger to be condensed.

[0022] In some embodiments of the present disclosure, the indoor heat exchanger further includes heat exchange fins to increase a contact area between the indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving a heat exchange efficiency of the indoor air and the refrigerant.

[0023] The indoor fan is configured to suck the indoor air into the indoor unit through a third air inlet 110 of the indoor unit and deliver the indoor air after heat exchange by the indoor heat exchanger out through a fourth air outlet 140 of the indoor unit. The indoor fan supplies power to flowing of the indoor air.

[0024] The cabinet air conditioner further includes a control device mainly configured to control a working frequency of the compressor, the opening degree of the expansion valve, a rotation speed of the outdoor fan and a rotation speed of the indoor fan. The control device is connected with the compressor, the expansion valve, the outdoor fan and the indoor fan through data cables to transmit communication information.

[0025] The control device includes a processor, and the processor may include a central processing unit (CPU), a microprocessor, and an application specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device.

[0026] As shown in FIG. 1 to FIG. 10, a cabinet air conditioner according to some embodiments of the present disclosure includes a ventilation assembly 200, and the ventilation assembly 200 can simultaneously suck fresh air into a room and discharge indoor air.

[0027] As shown in FIG. 1 to FIG. 10, the cabinet air conditioner may further include a cabinet 100 and a heat exchanger, the cabinet 100 having an upper chamber and a lower chamber. Both the upper chamber and the lower chamber can achieve accommodating and mounting functions, and other corresponding components in the cabinet air conditioner can be mounted in the upper chamber and the lower chamber.

[0028] For example, the heat exchanger may be arranged in the upper chamber, so that the heat exchanger may be separated from the lower chamber. The heat exchanger may achieve a heat exchange function in the upper chamber, so as to perform heat exchange on indoor air. The ventilation assembly 200 may be arranged in the lower chamber.

[0029] As shown in FIG. 1 to FIG. 5, the ventilation assembly 200 is configured to deliver outdoor air into a room and deliver the indoor air to the outside. That is, the ventilation assembly 200 can discharge the indoor dirty air to the outside while delivering the outdoor fresh air into the room, thereby better refreshing the indoor air.

[0030] The ventilation assembly 200 includes a first air duct member 210, the outdoor fresh air enters the room through the first air duct member 210, a first air inlet 211 and a first air outlet 212 are formed in the first air duct member 210, and a first air duct 201 is formed between the first air inlet 211 and the first air outlet 212. The ventilation assembly 200 further includes a second air duct member 220, the indoor air is exhausted from the room through the second air duct member 220, a second air inlet 221 and a second air outlet 222 are formed in the second air duct member 220, and a second air duct 202 is formed between the second air inlet 221 and the second air outlet 222.

[0031] The first air duct 210 is a fresh air duct, the first air inlet 211 is a fresh air inlet configured to introduce the outdoor fresh air into the first air duct member 210, and the first air outlet 212 is a fresh air outlet configured to discharge the outdoor fresh air out of the first air duct member 210 into the room. The second air duct 220 is an exhaust air duct, the second air inlet 221 is an indoor air inlet configured to introduce the indoor air into the second air duct member 220, and the second air outlet 222 is an indoor air outlet configured to discharge the indoor turbid air to the outside.

[0032] The first air duct member 210 is a structural member through which an air stream passes, and the first air duct member 210 is arranged in the lower chamber. Thus, the arrangement of the first air duct member 210 is more reasonable, interference with heat exchange of the upper chamber can be avoided, and the first air duct member 210 can better achieve an air stream passing function.

[0033] The first air inlet 211 mainly plays an air inlet role, the first air outlet 212 mainly plays an air outlet role, and the first air duct 201 can achieve the function of guiding air circulation. The outdoor fresh air enters the first air duct member 210 through the first air inlet 211, and then enters the room through the first air outlet 212 along the first air duct 201, so that the outdoor fresh air can be introduced.

[0034] Similarly, the second air duct member 220 is also a structural member through which an air stream passes, and the second air duct member 220 is arranged in the lower chamber, so that the arrangement of the second air duct member 220 is more reasonable, interference with heat exchange of the upper chamber can be avoided, and the second air duct member 220 can better achieve an air stream passing function.

[0035] The second air inlet 221 mainly plays an air inlet role, the second air outlet 222 mainly plays an air outlet role, and the second air duct 202 can achieve the function of guiding air circulation. The indoor dirty air enters the second air duct member 220 through the second air inlet 221, and then is discharged to the outside through the second air outlet 222 along the second air duct 202, so that the indoor dirty air can be discharged.

[0036] As shown in FIG. 3, the ventilation assembly 200 further includes a first fan 300, and the first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the outside. This arrangement is more reasonable, and when the first fan 300 works, the first fan 300 sucks the indoor dirty air into the second air duct 202, and then discharges the indoor dirty air to the outside from the second air duct 202, so that the indoor dirty air can be discharged. The first fan 300 may be an exhaust fan.

[0037] As shown in FIG. 3, the ventilation assembly 200 further includes a second fan 400, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. This arrangement is more reasonable, and when the second fan 400 works, the second fan 400 can suck the outdoor fresh air into the first air duct 201, and then release the outdoor fresh air into the room from the first air duct 201, so that the outdoor fresh air can be introduced. The second fan 400 may be a fresh air fan.

[0038] As shown in FIG. 3 and FIG. 6, the ventilation assembly 200 further includes an electric motor 500, the electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate.

[0039] The electric motor 500 mainly achieves a driving function, and the electric motor 500 has the single output shaft 510. That is, the electric motor 500 outputs power outwards through only one output shaft 510. The first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. When the electric motor 500 works, the electric motor 500 may simultaneously drive the first fan 300 and the second fan 400 to rotate through the output shaft 510. In this way, the second fan 400 can suck the outdoor fresh air while the first fan 300 discharges the indoor dirty air.

[0040] As shown in FIG. 3, FIG. 7 and FIG. 8, the electric motor 500 is arranged in one of the first fan 300 and the second fan 400, and one of the first fan 300 and the second fan 400 is provided with an accommodating portion 310 to accommodate the electric motor 500. The other of the first fan 300 and the second fan 400 is provided with a clearance portion 410 to clear the accommodating portion 310, and the accommodating portion 310 is provided corresponding to the clearance portion 410.

[0041] For example, as shown in FIG. 7 and FIG. 8, the first fan 300 is provided with the accommodating portion 310, the second fan 400 is provided with the clearance portion 410, and the electric motor 500 may be arranged in the accommodating portion 310 of the first fan 300. In this way, the electric motor 500 may be arranged inside the first fan 300. Moreover, the clearance portion 410 may clear the accommodating portion 310. That is, the accommodating portion 310 may be located within the clearance portion 410. In this way, a size of the clearance portion 410 and the accommodating portion 310 in a fitting direction may be reduced, thereby reducing a volume of the ventilation assembly 200.

[0042] In addition, the clearance portion 410 is arranged opposite to the accommodating portion 310, so that a size of the clearance portion 410 and the accommodating portion 310 in an opposite direction can be reduced, thereby reducing the volume of the ventilation assembly 200. The accommodating portion 310 may have a convex structure, and the clearance portion 410 may have a concave structure.

[0043] In addition, one of the first fan 300 and the second fan 400 is provided with a first rotation stopping portion 320, the other is provided with a second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at a same frequency.

[0044] It should be noted that the first rotation stopping portion 320 fits the second rotation stopping portion 420 to stop rotation of the second fan 400 and the first fan 300 in a circumferential direction of the output shaft 510. That is, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Meanwhile, the first rotation stopping portion 320 fits the second rotation stopping portion 420 to position assembly of the second fan 400 and the first fan 300.

[0045] Therefore, even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first rotation stopping portion 320 fits the second rotation stopping portion 420, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and in this case, the rotation speed of the second fan 400 is lower than that of the first fan 300. After the first rotation stopping portion 320 fits the second rotation stopping portion 420, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0046] Thus, by providing the accommodating portion 310 in one of the first fan 300 and the second fan 400, providing the clearance portion 410 in the other, and providing the electric motor 500 in the first fan 300 or the second fan 400, under the condition of simultaneously exhausting the air of the room and sucking the air into the room, the volume occupied by the ventilation assembly 200 can be reduced, a cost is reduced, and universality of the cabinet air conditioner is improved.

[0047] In addition, the accommodating portion 310 is formed to protrude from an end surface of one of the first fan 300 and the second fan 400 towards the other of the first fan 300 and the second fan 400 along an axis of the first fan 300. That is, a structure of the accommodating portion 310 is configured to be convex towards the clearance portion 410, and correspondingly, since the clearance portion 410 is provided corresponding to the accommodating portion 310, the clearance portion 410 is configured to be concave.

[0048] For example, the accommodating portion 310 is arranged on the first fan 300, the clearance portion 410 is arranged on the second fan 400, and the accommodating portion 310 protrudes towards the second fan 400 along the axis of the first fan 300. In this way, the accommodating portion 310 and the clearance portion 410 can be better matched to mount the electric motor 500 in the accommodating portion 310. Thus, an additional space occupied by the electric motor 500 may be reduced, thereby reducing the overall volume of the ventilation assembly 200.

[0049] In some embodiments of the present disclosure, as shown in FIG. 7, the accommodating portion 310 includes a first protrusion 311 and a second protrusion 312. The first protrusion 311 may be provided therein with a cavity, and the second protrusion 312 mainly achieves a connection function.

[0050] As shown in FIG. 3, FIG. 7 and FIG. 8, the first protrusion 311 protrudes towards the clearance portion 410, so that the first protrusion 311 can be better matched with the clearance portion 410, thereby reducing a volume of the first protrusion 311 and the clearance portion 410 after fitting. The electric motor 500 is at least partially arranged within the first protrusion 311. That is, the electric motor 500 is at least partially arranged within the cavity formed within the first protrusion 311. In this way, the electric motor 500 can conveniently fit the first fan 300 or the second fan 400, and the additional space occupied by the electric motor 500 can be reduced, thereby reducing the overall volume of the ventilation assembly 200.

[0051] As shown in FIG. 3 and FIG. 7, the second protrusion 312 protrudes towards the clearance portion 410, and the second protrusion 312 is connected to a side of the first protrusion 311 adjacent to the clearance portion 410. In this way, interference of the second protrusion 312 with the arrangement of the electric motor 500 can be avoided, and meanwhile, the size of the clearance portion 410 and the accommodating portion 310 in the opposite direction can be reduced. The electric motor 500 is in transmission connection with the second protrusion 312, so that the electric motor 500 can provide power for the second protrusion 312. That is, the electric motor 500 may drive the second protrusion 312 to rotate, so as to drive the first fan 300 or the second fan 400 to rotate, thereby exhausting the air or sucking the air.

[0052] In some embodiments of the present disclosure, as shown in FIG. 7, a sectional area of the first protrusion 311 gradually decreases towards the clearance portion 410. In this way, in the case of ensuring that the formed cavity is enough to fit the electric motor 500, a volume of the first protrusion 311 may be reduced, thereby reducing a manufacturing cost of the first protrusion 311. Moreover, the first protrusion 311 forms a structure with a slanted surface, which may improve structural strength of the accommodating portion 310 to some extent.

[0053] In some embodiments of the present disclosure, as shown in FIG. 3 and FIG. 8, the clearance portion 410 includes a plurality of connecting strips 411 and a connecting plate 412. The plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other, the connecting plate 412 is respectively connected with the plurality of connecting strips 411, and the electric motor 500 is also in transmission connection with the connecting plate 412.

[0054] The connecting strips 411 mainly achieve a connection function, and the plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other. That is, the plurality of connecting strips 411 have an inclined structure that converges towards a center, so that the inclined arrangement of the plurality of connecting strips 411 corresponds to the structure of the accommodating portion 310, and the accommodating portion 310 may be arranged opposite to the clearance portion 410. Moreover, the plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other. In this way, the accommodating portion 310 may be fitted between the plurality of connecting strips 411, so that the clearance portion 410 fits the accommodating portion 310, the size of the clearance portion 410 and the accommodating portion 310 in the opposite direction is reduced, and then, a volume of the first fan 300 and the second fan 400 after fitting may be reduced.

[0055] The connecting plate 412 mainly has a connection function, and the connecting plate 412 is connected with the plurality of connecting strips 411. Thus, the connecting plate 412 can be fixed, and the connecting plate 412 can be more firmly and stably arranged. Since the electric motor 500 is also in transmission connection with the connecting plate 412, the electric motor 500 can drive the connecting plate 412 to rotate while driving the second protrusion 312 to rotate. That is, the electric motor 500 may simultaneously drive the accommodating portion 310 and the clearance portion 410 to rotate, so as to simultaneously drive the first fan 300 and the second fan 400 to rotate, thereby simultaneously sucking the air into the room and exhausting the air of the room.

[0056] In some embodiments of the present disclosure, as shown in FIG. 1 to FIG. 5, the cabinet air conditioner further includes a first air duct shell 223, a second air duct shell 224 and a third air duct shell 213. The first air duct shell 223 constitutes a first part of the second air duct member 220, and the first air duct shell 223 constitutes a first part of the first air duct member 210. The second air duct shell 224 constitutes a second part of the second air duct member 220, and the third air duct shell 213 constitutes a second part of the first air duct member 210.

[0058] The first air duct shell 223 constitutes the first part of the second air duct member 220, and the second air duct shell 224 constitutes the second part of the second air duct member 220. That is, the first air duct shell 223 and the second air duct shell 224 may constitute the complete second air duct member 220, so that the indoor dirty air can be discharged inside the second air duct member 220. Certainly, the first fan 300 is arranged in the second air duct 202 in the second air duct member 220. Thus, the first fan 300 can suck the indoor dirty air into the second air duct member 220 through the second air inlet 221, and then discharge the indoor dirty air to the outside from the second air duct member 220 through the second air outlet 222, so as to exhaust the indoor air.

[0059] The first air duct shell 223 constitutes the first part of the first air duct member 210, and the third air duct shell 213 constitutes the second part of the first air duct member 210. That is, the first air duct shell 223 and the third air duct shell 213 may constitute the complete first air duct member 210. Thus, the outdoor fresh air can enter the first air duct member 210 through the first air inlet 211. Certainly, the second fan 400 is arranged in the fresh air duct of the first air duct member 210. Thus, the second fan 400 can suck the outdoor fresh air into the first air duct member 210 through the first air inlet 211, and then release the outdoor fresh air into the room from the first air duct member 210 through the first air outlet 212, so as to release the fresh air into the room.

The limiting portion 2231 is arranged on the first air duct shell 223, so that a fitting structure may be formed on the first air duct shell 223, and therefore, the first air duct shell 223 may better fit the second air duct shell 224 and the third air duct shell 213.

[0061] The limiting portion 2231 is located between the accommodating portion 310 and the clearance portion 410, and the limiting portion 2231 is provided to protrude towards the clearance portion 410. That is, protruding directions of the limiting portion 2231 and the accommodating portion 310 are the same. Thus, the accommodating portion 310 may better fit the limiting portion 2231, and meanwhile, the limiting portion 2231 may better fit the clearance portion 410, so that a volume of the first air duct shell 223, the second air duct shell 224, and the third air duct shell 213 after fitting may be reduced, and then, the overall volume of the ventilation assembly 200 may be reduced.

[0062] Further, as shown in FIG. 5 and FIG. 6, the cabinet air conditioner further includes a fastener 520.

[0063] The fastener 520 mainly achieves a fixing function, the output shaft 510 mainly achieves a torque transmission function, and the output shaft fixing portion 512 mainly achieves a fixing function. The output shaft 510 is arranged through the first fan 300 and the second fan 400, and the fastener 520 is fixed to the output shaft fixing portion 512. In this way, when the electric motor 500 simultaneously drives the first fan 300 and the second fan 400 to rotate, the first fan 300 and the second fan 400 can be limited in an axial direction of the output shaft 510 by the fastener 520, so that the first fan 300 and the second fan 400 can work more stably.

[0064] For example, as shown in FIG. 5 and FIG. 6, the fastener 520 is a nut, the output shaft fixing portion 512 is a threaded section having a surface provided with an external thread, and the nut fits the external thread. Thus, assembly between the fastener 520 and the output shaft fixing portion 512 can be simpler, a connection between the nut and the external thread is firm and stable, connection strength is high, and the nut and the external thread have simple structures and are convenient to process and provide.

[0065] In addition, as shown in FIG. 6, FIG. 9 and FIG. 10, the cabinet air conditioner further includes an electric motor bracket 530 and an electric motor pressing plate 540. The electric motor bracket 530 is fixed on the first air duct member 210 or the second air duct member 220, the electric motor pressing plate 540 is fixedly connected with the electric motor bracket 530, and the electric motor 500 is sandwiched between the electric motor bracket 530 and the electric motor pressing plate 540.

[0066] The electric motor bracket 530 mainly achieves a mounting function, the electric motor pressing plate 540 mainly achieves mounting and limiting functions, and by fixing the electric motor bracket 530 on the first air duct member 210 or the second air duct member 220, the electric motor bracket 530 can be fixed, and the electric motor bracket 530 is more firmly and stably arranged. The electric motor pressing plate 540 is fixedly connected with the electric motor bracket 530, so that the electric motor pressing plate 540 can be fixed, the electric motor 500 can be sandwiched between the electric motor bracket 530 and the electric motor pressing plate 540, and therefore, the electric motor 500 can be limited and fixed by the electric motor bracket 530 and the electric motor pressing plate 540, and the electric motor 500 can work more stably.

[0067] In addition, as shown in FIG. 9 and FIG. 10, the electric motor bracket 530 is provided with a first mounting portion 531, and the electric motor pressing plate 540 is provided with a second mounting portion 541.

[0068] Each of the first mounting portion 531 and the second mounting portion 541 can achieve a mounting function, and the first mounting portion 531 and the second mounting portion 541 are correspondingly mounted and connected. In this way, the electric motor bracket 530 and the electric motor pressing plate 540 may be connected together by the first mounting portion 531 and the second mounting portion 541, so that the connection of the electric motor bracket 530 and the electric motor pressing plate 540 may be more stable, and therefore, the electric motor 500 may work better.

Therefore, an assembling speed and assembling precision of the electric motor bracket 530 and the electric motor pressing plate 540 can be improved, and an assembling effect of the electric motor bracket 530 and the electric motor pressing plate 540 is improved.

[0070] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to FIG. 11 to FIG. 21.

[0071] Referring to FIG. 11 to FIG. 21, a cabinet air conditioner according to some embodiments of the present disclosure includes: a cabinet 100, a heat exchange blower, a first air duct member 210, a second air duct member 220, an electric motor 500, a first air duct 201, a second air duct 202, a purification air duct, a communication port 230, a first baffle 240 and a second baffle 250. The first air duct member 210 may be a fresh air duct member, the second air duct member 220 may be an exhaust air duct member, and the electric motor 500 may be a single-shaft electric motor.

[0072] An upper chamber and a lower chamber located below the upper chamber are formed inside the cabinet 100, and a third air inlet 110 and a third air outlet 120 are formed in the lower chamber. The second air duct 202 is defined from the third air inlet 110 to the third air outlet 120 in the cabinet air conditioner. The third air inlet 110 is an indoor air inlet, the third air outlet 120 is an indoor air outlet, a position of the third air inlet 110 corresponds to that of a second air inlet 221, so as to introduce indoor air into the cabinet through the third air inlet 110 and into the second air duct member 220 through the second air inlet 221, and a position of the third air outlet 120 corresponds to that of a second air outlet 222, so as to discharge indoor turbid air to the outside through the second air outlet 222 and the third air outlet 120 in sequence.

[0073] A fifth air inlet 160 and a fifth air outlet 170 are formed in the lower chamber, the first air duct 201 is defined between the fifth air inlet 160 and the fifth air outlet 170 in the cabinet air conditioner, the fifth air inlet 160 is a fresh air inlet, the fifth air outlet 170 is a fresh air outlet, a position of the fifth air inlet 160 corresponds to that of a first air inlet 211, so as to introduce outdoor fresh air into the cabinet through the fifth air inlet 160 and into the first air duct member 210 through the first air inlet 211, and a position of the fifth air outlet 170 corresponds to that of a first air outlet 212, so as to discharge the outdoor fresh air to the outside through the first air outlet 212 and the fifth air outlet 170 in sequence.

[0074] A fourth air inlet 130 and a fourth air outlet 140 are further formed in the lower chamber, and the purification air duct is defined from the fourth air inlet 130 to the fourth air outlet 140 in the cabinet air conditioner. The fourth air inlet 130 is a purified air inlet, the fourth air outlet 140 is a purified air outlet, and a position of the fourth air inlet 130 corresponds to that of the second air inlet 221, so that the indoor air is introduced into the cabinet through the fourth air inlet 130 and into the second air duct member 220 through the second air inlet 221, and the purified indoor air is discharged into a room through the fourth air outlet 140.

[0075] For example, the interior of the cabinet air conditioner is divided into an upper part and a lower part, the upper part is provided with the upper chamber, the lower part is provided with the lower chamber, and the upper chamber and the lower chamber are communicated through an air supply duct 150. The indoor air can enter the cabinet air conditioner from the third air inlet 110 formed in the lower chamber, and is exhausted to the outside from the third air outlet 120 after passing through the second air duct 202, and the outdoor fresh air can enter the cabinet air conditioner from the fifth air inlet 160 formed in the lower chamber, and is blown into the room from the fifth air outlet 170 after passing through the first air duct 201, so that the indoor air and the outdoor air can circulate to avoid that accumulation of harmful substances such as pollutants, bacteria and viruses in the indoor air lowers indoor air quality, which is not conducive to physical health of a user.

[0076] The lower chamber is further provided with the fourth air inlet 130 and the fourth air outlet 140, and when the user starts an indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet 130, and is discharged into the room from the fourth air outlet 140 after passing through the purification air duct, so that the indoor air can be filtered and purified, and the indoor air quality is improved. It should be noted that when the air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and in this case, the second air duct 202 is in an idle state.

[0077] In addition, the heat exchange blower is arranged in the upper chamber, and when the cabinet air conditioner operates, the heat exchange blower drives the indoor air to enter the cabinet 100, the indoor air forms a heat exchange air stream after exchanging heat with a heat exchanger, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room, so as to adjust an indoor temperature.

[0078] Referring to FIG. 11 to FIG. 13, the cabinet air conditioner further includes the first air duct member 210, the first air duct member 210 is arranged in the lower chamber, and the first air duct member 210 is configured to draw the outdoor air from the outside through the first air duct 201 and blow the air into the room. A fresh air cavity 214 is formed in the first air duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0079] That is, the first air duct member 210 is arranged in the lower chamber, the fresh air cavity 214 is formed inside the first air duct member 210, and the second fan 400 is arranged in the fresh air cavity 214. When the second fan 400 operates, the outdoor fresh air can be introduced from the fifth air inlet 160, discharged through the fifth air outlet 170 in the first air duct member 210, and driven by the heat exchange blower to enter the upper chamber from the air supply duct 150, and form a heat exchange air stream after exchanging heat with the heat exchanger in the upper chamber, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room. The fresh air is introduced and blown into the room through the first air duct member 210, so that the indoor air quality can be improved, more natural experience is provided for the user, and a use effect of the air conditioner is improved.

[0080] The cabinet air conditioner further includes the second air duct member 220, and the second air duct member 220 is arranged in the lower chamber and spaced apart from the first air duct member 210. The second air duct member 220 is configured to draw the indoor air from the room and discharge the air to the outside through the second air duct 202. An exhaust cavity 225 is formed in the second air duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0081] That is, the second air duct member 220 is arranged in the lower chamber, and the second air duct member 220 is spaced apart from the first air duct member 210 and located on a side of the first air duct member 210 away from the third air outlet 120. The exhaust cavity 225 is formed inside the second air duct member 220, and the first fan 300 is arranged in the exhaust cavity 225. When the first fan 300 operates, the indoor air can be introduced from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. Therefore, the dirty air accumulated in the room can be discharged to the outside, and the indoor air quality is improved.

[0082] In addition, the cabinet air conditioner further includes the electric motor 500, the electric motor 500 having a single output shaft 510, and the first fan 300 and the second fan 400 being connected to the output shaft 510. When the electric motor 500 operates, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 and the first air duct member 210 can fit each other to simultaneously suck the outdoor fresh air and discharge the indoor dirty air, so that good circulation of the indoor air is maintained, and the indoor air quality is improved.

[0083] The communication port 230 is configured to communicate the first air duct 201 and the exhaust air duct (second air duct 202). Since when the indoor air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, the second air duct 202 is in the idle state. Thus, under the condition that the communication port 230 is not blocked, when the outdoor air enters the first air duct 201 from the fifth air inlet 160, the outdoor air can also flow in the second air duct 202, and compared with a cabinet air conditioner in the related art, the cabinet air conditioner according to some embodiments of the present disclosure makes full use of existing components, and can effectively prevent the second air duct 202 from being idle without excessive modification, and moreover, a channel for introducing the fresh air into the cabinet air conditioner is changed from the original first air duct 201 to the first air duct 201 and the second air duct 202, so that an amount of the introduced fresh air can be increased, and the indoor air quality can be improved.

[0084] The cabinet air conditioner further includes the first baffle 240 and the second baffle 250, and the first baffle 240 is rotatably arranged in the second air duct 202 or the first air duct 201 to open or close the communication port 230. The second baffle 250 is rotatably arranged in the second air duct 202 or the purification air duct to communicate the third air inlet 110 and the third air outlet 120 and disconnect the third air inlet 110 from the fourth air outlet 140.

[0085] That is, the first baffle 240 may rotate within the second air duct 202 or the first air duct 201, and a rotation angle may be a clockwise angle or a counterclockwise angle. The first baffle 240 may be configured to open or close the communication port 230, so as to control communication between the first air duct 201 and the second air duct 202.

[0086] The second baffle 250 may rotate within the second air duct 202 or the purification air duct, and a rotation angle may be a clockwise angle or a counterclockwise angle. The second baffle 250 may be located at the purification air duct to block air flow between the third air inlet 110 and the fourth air outlet 140 and communicate the third air inlet 110 and the third air outlet 120. In this case, an exhaust mode runs normally. The second baffle 250 may be located at the second air duct 202, so as to block air flow between the third air inlet 110 and the third air outlet 120 and communicate the third air inlet 110 and the fourth air outlet 140, and in this case, the indoor air circulation purification mode is started.

[0087] Thus, by arranging the communication port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the communication port 230 fit each other to control communication and a disconnection of the first air duct 201 and the second air duct 202, the second baffle 250 can control switching between the exhaust mode and the indoor air circulation purification mode, and when the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are communicated through the communication port 230, and the second air duct 202 is changed into the first air duct 201, so that the amount of the fresh air of the cabinet air conditioner is increased, and the air quality of a human living environment is improved.

[0088] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, the first baffle 240 has a first position and a second position. When the first baffle 240 is located at the first position, the first baffle 240 blocks the communication port 230; when the first baffle 240 is located at the second position, the first baffle 240 opens the communication port 230, so that the first air duct member 210 draws the outdoor air from the outside through the first air duct 201 and the second air duct 202.

[0089] For example, when the first baffle 240 is at the first position, the first baffle 240 may block the communication port 230. In this case, air cannot circulate in the first air duct 201 and the second air duct 202, and the second air duct 202 and the first air duct 201 function to discharge the indoor dirty air and suck the outdoor fresh air respectively.

[0090] For another example, after the first baffle 240 is rotated clockwise by an angle, the first baffle 240 is located at the second position. In this case, the first baffle 240 does not block the communication port 230, the air can circulate in the first air duct 201 and the second air duct 202, the second air duct 202 can be used as the first air duct 201, and the fresh air is introduced by the first air duct 201 and the second air duct 202 simultaneously, so that the amount of the fresh air is increased, more fresh air is introduced into the room, and the indoor air quality is improved.

[0091] When the cabinet air conditioner is not in the indoor air circulation purification mode, the first baffle 240 may be rotated counterclockwise by an angle to return to the first position to block the communication port 230, so that the second air duct 202 and the first air duct 201 function to discharge the indoor dirty air and suck the outdoor fresh air respectively.

[0092] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, when the first baffle 240 is located at the first position, an orthographic projection of the first baffle 240 on a horizontal plane covers an orthographic projection of the communication port 230 on the horizontal plane. That is, an area of the first baffle 240 is larger than an area of the communication port 230, and the orthographic projection of the first baffle 240 on the horizontal plane can cover the orthographic projection of the communication port 230 on the horizontal plane. Thus, the first baffle 240 can effectively block the communication port 230 when located at the first position, thus avoiding the overflow of the air from the communication port 230 into the second air duct 202 or the first air duct 201 when the second air duct 202 discharges the indoor air or the first air duct 201 sucks the outdoor air, which would otherwise mix the indoor air and hinder the improvement of the indoor air quality. The horizontal plane may be a plane of the first baffle 240 at the communication port 230.

[0093] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, the second baffle 250 has a third position and a fourth position. When the second baffle 250 is located at the third position, the second baffle 250 disconnects the third air inlet 110 from the third air outlet 120 and communicates the third air inlet 110 and the fourth air inlet 130. When the second baffle 250 is located at the fourth position, the second baffle 250 disconnects the third air inlet 110 from the fourth air outlet 140 and communicates the third air inlet 110 and the third air outlet 120.

[0094] For example, when the second baffle 250 is located at the third position, the second baffle 250 may disconnect the third air inlet 110 from the third air outlet 120, and due to the blocking of the second baffle 250, the indoor air drawn by the second air duct member 220 cannot be discharged to the outside through the second air duct 202, and can only be delivered into the room, and in this case, the cabinet air conditioner is in the indoor air circulation purification mode, and the second air duct 202 is in the idle state. In this case, the first baffle 240 may be located at the second position, the communication port 230 communicates the first air duct 201 with the second air duct 202, and the first air duct member 210 may introduce the outdoor fresh air from the first air duct 201 and the second air duct 202 at the same time, so that an amount of the indoor fresh air is increased, and the air quality of the indoor human living environment is greatly improved.

[0095] For another example, when the second baffle 250 is located at the fourth position, the second baffle 250 is rotated counterclockwise by an angle from the third position. Thus, the third air inlet 110 and the third air outlet 120 are communicated. In this case, the first baffle 240 may be at the first position to block the communication port 230, the second air duct 202 may be separated from the first air duct 201, the air drawn from the room by the second air duct member 220 may sequentially pass through the third air outlet 120 and the second air duct 202 to be discharged to the outside, and the dirty air accumulated in the room may be discharged, so that circulation of the indoor air may be maintained, and the indoor air quality may be improved.

[0096] In some embodiments of the present disclosure, referring to FIG. 14 and FIG. 15, the second baffle 250 and the first baffle 240 are of an integrally formed structure. A pivot portion 241 of the first baffle 240 and the second baffle 250 is arranged at an interface between the second baffle 250 and the first baffle 240, so that the first baffle 240 and the second baffle 250 rotate about the pivot portion 241. The cabinet air conditioner further includes a first driving member which is in transmission fit with the pivot portion 241. For example, the pivot portion 241 is arranged between the first baffle 240 and the second baffle 250, the cabinet air conditioner is provided with the first driving member, and the first driving member is in transmission fit with the pivot portion 241. That is, the first driving member may drive the first baffle 240 and the second baffle 250 to rotate about the pivot portion 241, and the first driving member may be the electric motor 500. The first baffle 240 and the second baffle 250 are of the integrally formed structure, and rotation ranges of the first baffle 240 and the second baffle 250 are both angles.

[0097] Thus, the second baffle 250 is at the fourth position when the first baffle 240 is at the first position. In this case, the first baffle 240 blocks the communication port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 and the third air outlet 120 are communicated with each other. In this case, the second air duct 202 is only configured to fit the second air duct member 220 to discharge the indoor air, thus maintaining the circulation of the indoor air.

[0098] When the first baffle 240 is at the second position, the second baffle 250 is at the third position. In this case, the communication port 230 between the second air duct 202 and the first air duct 201 is opened, the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250, and the indoor air drawn by the second air duct member 220 cannot be discharged through the second air duct 202, is then output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, so that the indoor air circulation purification mode is formed. Under driving of the first air duct member 210, the second air duct 202 and the first air duct 201 are communicated to jointly draw the fresh air from the outside, so that the second air duct 202 is used to introduce the fresh air while the indoor air circulation purification mode is realized, the second air duct 202 is prevented from being idle, the amount of the fresh air can be increased, the indoor air is kept fresh, and the air quality of the indoor human living environment is improved greatly.

[0099] In some embodiments of the present disclosure, referring to FIG. 15, a clearance space 251 is formed between the first baffle 240 and the second baffle 250. When the second baffle 250 is located at the third position and the first baffle 240 is located at the second position, an orthographic projection of the clearance space 251 on the horizontal plane covers the orthographic projection of the communication port 230 on the horizontal plane, so that the clearance space 251 is communicated with the communication port 230. Since the first baffle 240 and the second baffle 250 are of the integrally formed structure, in order to achieve the aim that the communication port 230 is not blocked when the first baffle 240 rotates to the second position and the second baffle 250 rotates to the third position, the clearance space 251 is formed between the first baffle 240 and the second baffle 250, and when the second baffle 250 is located at the third position, the orthographic projection of the clearance space 251 on the horizontal plane covers the orthographic projection of the communication port 230 on the horizontal plane.

[0100] That is, an area of the clearance space 251 is larger than the area of the communication port 230, and when the first baffle 240 and the second baffle 250 rotate around the pivot portion 241 to the second position and the third position, the first baffle 240 and the second baffle 250 do not block the communication port 230, so that smooth air circulation between the second air duct 202 and the first air duct 201 can be ensured, and a large amount of fresh air can be introduced.

[0101] The cabinet air conditioner further includes a second driving member and a third driving member. The second driving member is in transmission connection with the first baffle 240, so as to drive the first baffle 240 to rotate between the first position and the second position. The third driving member is in transmission connection with the second baffle 250, so as to drive the second baffle 250 to rotate between the third position and the fourth position. That is, the first baffle 240 and the second baffle 250 may be driven by different driving members, the cabinet air conditioner further includes the second driving member and the third driving member, the second driving member is in transmission connection with the first baffle 240, the third driving member is in transmission connection with the second baffle 250, and the second driving member and the third driving member respectively drive the first baffle 240 and the second baffle 250 to rotate.

[0102] Thus, the second baffle 250 may be at the third position when the first baffle 240 is at the first position. In this case, the communication port 230 is blocked by the first baffle 240, the third air inlet 110 and the third air outlet 120 are also separated by the second baffle 250, the air drawn from the room by the second air duct member 220 can only be output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, the second air duct member 220 only performs the indoor air circulation purification mode, and the second air duct 202 is in the idle state. The second baffle 250 may also be at the fourth position when the first baffle 240 is at the first position. In this case, the first baffle 240 blocks the communication port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 and the third air outlet 120 are communicated with each other. In this case, the second air duct 202 is only configured to fit the second air duct member 220 to discharge the indoor air, thus maintaining the circulation of the indoor air.

[0103] When the first baffle 240 is at the second position, the second baffle 250 may be at the third position. In this case, the communication port 230 between the second air duct 202 and the first air duct 201 is opened, the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250, and the indoor air drawn by the second air duct member 220 cannot be discharged through the second air duct 202, is then output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, so that the indoor air circulation purification mode is formed. Under driving of the first air duct member 210, the second air duct 202 and the first air duct 201 are communicated to jointly draw the fresh air from the outside, so that the second air duct 202 is used to introduce the fresh air while the indoor air circulation purification mode is realized, the second air duct 202 is prevented from being idle, the amount of the fresh air can be increased, the indoor air is kept fresh, and the air quality of the indoor human living environment is improved greatly.

[0104] However, when the first baffle 240 is located at the second position, the second baffle 250 cannot be located at the fourth position, otherwise, when the second air duct 202 is communicated with the first air duct 201, the third air inlet 110 is also communicated with the third air outlet 120, so that the indoor dirty air and the outdoor fresh air are mixed to reduce the indoor fresh air and reduce the air quality.

[0105] In some embodiments of the present disclosure, referring to FIG. 14, the second air duct member 220 is provided with the second air inlet 221, and the second air inlet 221 and the third air inlet 110 are oppositely arranged. The cabinet air conditioner further includes an exhaust filter portion 226, and the exhaust filter portion 226 is fixed to an inner side of the cabinet 100 and sandwiched between the third air inlet 110 and the second air inlet 221. The indoor air is driven by the second air duct member 220 to enter the second air duct 202 through the second air inlet 221 and the third air inlet 110, and since the exhaust filter portion 226 is sandwiched between the third air inlet 110 and the second air inlet 221, the indoor air sucked by the second air duct member 220 can be filtered, and the air filtered by the exhaust filter portion 226 enters the room from the purification air duct to participate in indoor air circulation, so that the indoor air can be purified, and the air quality is improved. The exhaust filter portion 226 may be a filter screen.

[0106] In some embodiments of the present disclosure, referring to FIG. 14, the cabinet air conditioner further includes a fresh air filter portion 215, and the fresh air filter portion 215 is arranged in the first air duct 201 and opposite to the fifth air inlet 160. Since the second fan 400 operates to suck the outdoor fresh air into the first air duct 201 through the fifth air inlet 160, and the fresh air filter portion 215 is arranged in the first air duct 201 and opposite to the fifth air inlet 160, the air sucked from the outside is filtered by the fresh air filter portion 215, so that cleanliness of the air blown out by the air conditioner can be improved, and an improvement of the human living environment is facilitated. The fresh air filter portion 215 may be a filter screen.

[0107] As shown in FIG. 14 and FIG. 16, the cabinet air conditioner further includes an opening-closing member 161, the opening-closing member 161 is rotatably arranged at the fifth air inlet 160, and the opening-closing member 161 has a fifth position and a sixth position. When the opening-closing member 161 is located at the fifth position, the opening-closing member 161 closes the fifth air inlet 160, and when the opening-closing member 161 is located at the sixth position, the opening-closing member 161 opens the fifth air inlet 160.

[0108] For example, the opening-closing member 161 is located at the fifth air inlet 160 and configured to control opening and closing of the first air duct 201. When the first air duct member 210 stops operating and the opening-closing member 161 is located at the fifth position, the opening-closing member 161 closes the fifth air inlet 160, so that noise generated when outdoor air flows backwards into the first air duct member 210 can be effectively avoided, and a good silencing effect is provided for an indoor space. When the opening-closing member 161 is located at the sixth position, the opening-closing member 161 opens the fifth air inlet 160, and the outdoor fresh air can enter the cabinet 100 from the fifth air inlet 160 to provide fresh air for the room. The opening-closing member 161 may be controlled by the electric motor 500.

[0109] Referring to FIG. 11 to FIG. 21, a cabinet air conditioner according to some embodiments of the present disclosure includes: a cabinet 100, a heat exchange blower, a first air duct member 210, a second air duct member 220, an electric motor 500, a first air duct 201, a second air duct 202, a purification air duct, a communication port 230, a first baffle 240 and a second baffle 250.

[0110] An upper chamber and a lower chamber located below the upper chamber are formed inside the cabinet 100, and a third air inlet 110 and a third air outlet 120 are formed in the lower chamber. The lower chamber is provided with a fifth air inlet 160 and a fifth air outlet 170. The lower chamber is further provided with a fourth air inlet 130 and a fourth air outlet 140, and the heat exchange blower is arranged in the upper chamber. In addition, in the cabinet air conditioner, the first air duct 201 is defined from the fifth air inlet 160 to the fifth air outlet 170, the second air duct 202 is defined from the third air inlet 110 to the third air outlet 120, and the purification air duct is defined from the fourth air inlet 130 to the fourth air outlet 140.

[0111] For example, the interior of the cabinet air conditioner is divided into an upper part and a lower part, the upper part is provided with the upper chamber, the lower part is provided with the lower chamber, and the upper chamber and the lower chamber are communicated through an air supply duct 150. Indoor air can enter the cabinet air conditioner from the third air inlet 110 formed in the lower chamber, and is exhausted to the outside from the third air outlet 120 after passing through the second air duct 202. Outdoor fresh air can enter the cabinet air conditioner from the fifth air inlet 160 formed in the lower chamber, and is blown into a room from the fifth air outlet 170 after passing through the first air duct 201. Therefore, the indoor air and the outdoor air can circulate, and it is avoided that accumulation of harmful substances such as pollutants, bacteria and viruses in the indoor air reduces indoor air quality.

[0112] The fourth air inlet and the fourth air outlet are also formed in the lower chamber. When a user starts an indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet, and is discharged into the room from the fourth air outlet after passing through the purification air duct, so that the indoor air can be filtered and purified, and the indoor air quality is improved. It should be noted that when the air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and in this case, the second air duct 202 is in an idle state.

[0113] In addition, the heat exchange blower is arranged in the upper chamber. When the cabinet air conditioner operates, the heat exchange blower drives the indoor air to enter the cabinet 100, the indoor air forms a heat exchange air stream after exchanging heat with a heat exchanger, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room, so as to adjust an indoor temperature.

[0114] Referring to FIG. 12 and FIG. 13, the cabinet air conditioner further includes the first air duct member 210, the first air duct member 210 is arranged in the lower chamber, and the first air duct member 210 is configured to draw the outdoor air from the outside through the first air duct 201 and blow the air into the room. A fresh air cavity 214 is formed in the first air duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0115] That is, the first air duct member 210 is arranged in the lower chamber, the fresh air cavity 214 is formed inside the first air duct member 210, and the second fan 400 is arranged in the fresh air cavity 214. When the second fan 400 operates, the outdoor fresh air can be introduced from the fifth air inlet 160, discharged through the fifth air outlet 170 in the first air duct member 210, and driven by the heat exchange blower to enter the upper chamber from the air supply duct 150, and form a heat exchange air stream after exchanging heat with the heat exchanger in the upper chamber, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room. The fresh air is introduced and blown into the room through the first air duct member 210, so that the indoor air quality can be improved, more natural experience is provided for the user, and a use effect of the air conditioner is improved.

[0116] The cabinet air conditioner further includes the second air duct member 220, and the second air duct member 220 is arranged in the lower chamber and spaced apart from the first air duct member 210. The second air duct member 220 is configured to draw the indoor air from the room and discharge the air to the outside through the second air duct 202. An exhaust cavity 225 is formed in the second air duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0117] That is, the second air duct member 220 is arranged in the lower chamber, and the second air duct member 220 is spaced apart from the first air duct member 210 and located on a side of the first air duct member 210 away from the third air outlet 120. The exhaust cavity 225 is formed inside the second air duct member 220, and the first fan 300 is arranged in the exhaust cavity 225. When the first fan 300 operates, the indoor air can be introduced from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. Therefore, the dirty air accumulated in the room can be discharged to the outside, and the indoor air quality is improved.

[0118] In addition, the cabinet air conditioner further includes the electric motor 500, the electric motor 500 having a single output shaft 510, and the first fan 300 and the second fan 400 being connected to the output shaft 510. When the electric motor 500 operates, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 and the first air duct member 210 can fit each other to simultaneously suck the outdoor fresh air and discharge the indoor dirty air, so that good circulation of the indoor air is maintained, and the indoor air quality is improved.

[0119] The communication port 230 is configured to communicate the first air duct 201 and the exhaust air duct (second air duct 202). Since when the indoor air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, the second air duct 202 is in the idle state. In this way, when the communication port 230 is not blocked, the outdoor air may flow in the second air duct 202 when entering the first air duct 201 from the fifth air inlet 160. Compared with a cabinet air conditioner in the related art, the cabinet air conditioner according to some embodiments of the present disclosure makes full use of existing components, and can effectively prevent the second air duct 202 from being idle without excessive modification. Moreover, a channel for introducing the fresh air into the cabinet air conditioner is changed from the original first air duct 201 to the first air duct 201 and the second air duct 202, so that an amount of the introduced fresh air can be increased, and the indoor air quality can be improved.

[0120] The cabinet air conditioner further includes the first baffle 240 and the second baffle 250, and the first baffle 240 is rotatably arranged at the communication port 230 to open or close the communication port 230. The second baffle 250 is rotatably arranged in the second air duct 202 or the purification air duct to communicate the third air inlet 110 and the third air outlet 120 and disconnect the third air inlet 110 from the fourth air outlet.

[0121] That is, the first baffle 240 may rotate at the communication port 230, and a rotation angle may be a clockwise angle or a counterclockwise angle. The first baffle 240 may be configured to open or close the communication port 230, so as to control communication between the first air duct 201 and the second air duct 202.

[0122] The second baffle 250 may rotate within the second air duct 202 or the purification air duct, and a rotation angle may be a clockwise angle or a counterclockwise angle. The second baffle 250 may be located at the purification air duct to block air flow between the third air inlet 110 and the fourth air outlet and communicate the third air inlet 110 and the third air outlet 120. In this case, an exhaust mode runs normally. The second baffle 250 may be located at the second air duct 202, so as to block air flow between the third air inlet 110 and the third air outlet 120 and communicate the third air inlet 110 and the fourth air outlet, and in this case, the indoor air circulation purification mode is started.

[0123] Thus, by arranging the communication port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the communication port 230 fit each other to control communication and a disconnection of the first air duct 201 and the second air duct 202. The second baffle 250 can control switching between the exhaust mode and the indoor air circulation purification mode, and when the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are communicated through the communication port 230, and the second air duct 202 is changed into the first air duct 201, so that the amount of the fresh air of the cabinet air conditioner is increased, and the air quality of a human living environment is improved.

[0124] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0125] As shown in FIG. 22 to FIG. 29, a cabinet air conditioner according to some embodiments of the present disclosure includes a cabinet 100, a heat exchanger, a heat exchange blower, and a ventilation assembly 200.

The exhaust filter portion 226 is arranged on an air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0129] As shown in FIG. 24 to FIG. 29, the mounting bracket 600 includes a bracket body 610, an electric motor mounting portion 620, and a filter mounting portion 630.

The electric motor 500 is mounted to the electric motor mounting portion 620. The filter mounting portion 630 is connected to the bracket body 610, and the exhaust filter portion 226 is mounted to the filter mounting portion 630.

[0130] The exhaust filter portion 226 may be a filter screen. The electric motor 500 has the single output shaft 510, which means that the electric motor 500 has only one output shaft 510, the output shaft 510 extends from one side of the electric motor 500, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510.

[0131] In the cabinet air conditioner according to some embodiments of the present disclosure, the cabinet 100 is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, and the heat exchange blower is configured to deliver the air subjected to heat exchange with the heat exchanger into the room. The ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0132] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0133] Moreover, the electric motor 500 has the single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. Thus, the first fan 300 and the second fan 400 can share one electric motor 500, which is beneficial to reducing a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated. Moreover, the exhaust filter portion 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter portion 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving quality of the air entering the cabinet air conditioner, and can improve quality of outlet air of the air conditioner and prevent dust and impurities from entering the cabinet 100.

[0134] In addition, the mounting bracket 600 includes the bracket body 610, the electric motor mounting portion 620, and the filter mounting portion 630. The electric motor 500 is mounted to the electric motor mounting portion 620, the filter mounting portion 630 is connected to the bracket body 610, and the exhaust filter portion 226 is mounted to the filter mounting portion 630.

That is, the electric motor 500 and the exhaust filter portion 226 may be mounted on one bracket. Thus, a number of the brackets can be reduced, an integration level of the mounting bracket 600 is higher, assembly is more convenient and faster, and an improvement of an assembly efficiency is facilitated.

[0136] Moreover, it can be understood that, compared to the related art in which two brackets are provided to fix the electric motor 500 and the exhaust filter portion 226 respectively, in the cabinet air conditioner according to some embodiments of the present disclosure, one bracket may be omitted, thereby saving a set of molds for producing the bracket and facilitating a reduction of a production cost of the mounting bracket 600.

[0137] In addition, the bracket body 610 is connected with the second air duct member 220, the electric motor mounting portion 620 is connected to the bracket body 610, and the electric motor mounting portion 620 extends into the second air duct member 220, so that the filter mounting portion 630 may be located outside the second air duct member 220. Therefore, the electric motor 500 can extend into the second air duct member 220 after being mounted to the electric motor mounting portion 620, and the electric motor 500 can be close to the first fan 300 and the second fan 400, so as to facilitate the output shaft 510 of the electric motor 500 to be in transmission connection with the first fan 300 and the second fan 400 respectively. In addition, the exhaust filter portion 226 may be located outside the second air duct member 220 after being mounted to the filter mounting portion 630, so that the indoor air entering the second air duct member 220 can be filtered before entering the second air duct member 220, and the dust and the impurities are more effectively prevented from entering the second air duct member 220, so as to keep the interior of the second air duct member 220 clean, thereby improving the quality of the outlet air of the cabinet air conditioner.

[0138] In this way, in the cabinet air conditioner according to some embodiments of the present disclosure, the electric motor 500 and the exhaust filter portion 226 can be simultaneously fixed by the mounting bracket 600, and the cabinet air conditioner has the advantages of a high integration level, convenient assembly, cost saving, or the like.

[0139] In some embodiments of the present disclosure, as shown in FIG. 25, FIG. 27, and FIG. 28, the filter mounting portion 630 includes a frame 631 and a latch 632.

[0140] The frame 631 is connected to a side of the bracket body 610 facing away from the electric motor mounting portion 620, and the frame 631 and the bracket body 610 together form an accommodating space for accommodating the exhaust filter portion 226. The latch 632 is connected to the frame 631, and the latch 632 is located on a side of the exhaust filter portion 226 facing away from the bracket body 610 and configured to stop the exhaust filter portion 226.

[0141] For example, the frame 631 may have a circular shape, a rectangular shape, a polygonal shape, or another shape, and the shape may be configured according to a shape of the exhaust filter portion 226, so as to enable the frame 631 to surround the exhaust filter portion 226.

[0142] The exhaust filter portion 226 may be parallel to the bracket body 610, and the bracket body 610 may be configured to separate the electric motor mounting portion 620 from the filter mounting portion 630. That is, the electric motor mounting portion 620 and the exhaust filter portion 226 may be respectively located on two opposite sides of the bracket body 610 in a thickness direction. In this way, the electric motor 500 and the exhaust filter portion 226 can be respectively located on the two opposite sides of the bracket body 610 in the thickness direction, so that the electric motor 500 and the exhaust filter portion 226 can be separated by the bracket body 610, position interference of the electric motor 500 and the exhaust filter portion 226 can be avoided, and a structure arrangement is more reasonable.

[0143] In addition, the frame 631 can extend along a circumferential direction of the exhaust filter portion 226, and then, an edge of the exhaust filter portion 226 can be blocked by the frame 631, which is beneficial to improving a protection effect on the exhaust filter portion 226. Moreover, the latch 632 and the bracket body 610 can respectively abut against two opposite sides of the exhaust filter portion 226 in a thickness direction, the bracket body 610 can prevent the exhaust filter portion 226 from excessively extending into the mounting bracket 600, and the latch 632 can prevent the exhaust filter portion 226 from being separated from the mounting bracket 600, so that a connection between the exhaust filter portion 226 and the mounting bracket 600 is more stable and reliable.

[0144] It should be noted that a plurality of latches 632 may be provided, and the plurality of latches 632 are distributed along a circumferential direction of the frame 631 at intervals, and then can be stopped at a plurality of positions of the exhaust filter portion 226 in the circumferential direction, so as to further improve the connection reliability of the exhaust filter portion 226 and the mounting bracket 600, prevent the exhaust filter portion 226 from being separated from the mounting bracket 600, and enable the exhaust filter portion 226 to more stably cover an air inlet side of the second air duct member 220.

[0145] In some embodiments of the present disclosure, as shown in FIG. 28, a side of the frame 631 facing away from the bracket body 610 is provided with a turned edge 633, and the turned edge 633 is bent away from the exhaust filter portion 226.

[0146] By providing the turned edge 633, structural strength of the frame 631 can be improved, and the frame 631 is not easily deformed, so that connection strength of the frame 631 and the exhaust filter portion 226 is higher, and the frame 631 can more reliably fix the exhaust filter portion 226. Moreover, by bending the turned edge 633 away from the exhaust filter portion 226, a position of the turned edge 633 does not interfere with that of the exhaust filter portion 226, thus facilitating assembly of the exhaust filter portion 226 and the mounting bracket 600.

[0147] In some embodiments of the present disclosure, as shown in FIG. 27 and FIG. 28, a side of the electric motor mounting portion 620 facing the exhaust filter portion 226 protrudes from the bracket body 610, and the exhaust filter portion 226 is sandwiched between the electric motor mounting portion 620 and the latch 632.

[0148] For example, the side of the electric motor mounting portion 620 facing the exhaust filter portion 226 protrudes from a side of the bracket body 610 facing the exhaust filter portion 226, which facilitates the electric motor mounting portion 620 and the latch 632 to respectively abut against the two opposite sides of the exhaust filter portion 226 in the thickness direction, so that the exhaust filter portion 226 is positioned more stably, and the exhaust filter portion 226 is prevented from moving.

[0149] It can be understood that the electric motor 500 and the exhaust filter portion 226 are respectively located on the two opposite sides of the bracket body 610, and by causing the side of the electric motor mounting portion 620 facing the exhaust filter portion 226 to protrude from the bracket body 610, the exhaust filter portion 226 can be spaced apart from the bracket body 610 after abutting against the electric motor mounting portion 620, so that the exhaust filter portion 226 and the electric motor 500 can have a larger distance, thus further avoiding position interference of the exhaust filter portion 226 and the blower.

[0150] In some embodiments of the present disclosure, as shown in FIG. 26 and FIG. 29, the electric motor mounting portion 620 includes a base 621 and a plurality of fixing posts 622.

[0151] The base 621 is configured to support one axial end of the electric motor 500, one end of each fixing post 622 is respectively connected to the base 621 and the bracket body 610, the plurality of fixing posts 622 are arranged along a circumferential direction of the electric motor 500, and the electric motor 500 is mounted among the plurality of fixing posts 622.

[0152] For example, a sectional area of an end of the fixing post 622 facing the bracket body 610 may be larger, so that the end of the fixing post 622 facing the bracket body 610 can be conveniently and fixedly connected with the base 621 and the bracket body 610 respectively.

[0153] After the electric motor 500 is mounted on the electric motor mounting portion 620, a stop plate may be connected to an end of the fixing post 622 facing away from the base 621, the stop plate may be stopped at an end of the electric motor 500 facing away from the base 621, and a via hole may be formed in a center of the stop plate, so as to facilitate the output shaft 510 to pass through the stop plate. The stop plate may be a same component as the electric motor pressing plate 540 in the above embodiment.

[0154] In addition, at least three fixing posts 622 may be provided. Thus, the plurality of fixing posts 622 can position the electric motor 500 in a radial direction and prevent the electric motor 500 from radially shifting relative to the electric motor mounting portion 620, and the base 621 and the stop plate may be respectively stopped at two axial ends of the electric motor 500 to fix the electric motor 500 in an axial direction of the electric motor 500, so as to prevent the electric motor 500 from axially shifting.

[0155] In some embodiments of the present disclosure, as shown in FIG. 24 and FIG. 26 to FIG. 29, at least one of the bracket body 610 and the electric motor mounting portion 620 is provided with a first wire passing portion 611, and the filter mounting portion 630 is provided with a second wire passing portion 634. A wire harness 550 of the electric motor 500 sequentially passes through the first wire passing portion 611 and the second wire passing portion 634. The first wire passing portion 611 may be configured as a first wire passing hole, and the second wire passing portion 634 may be configured as a second wire passing hole.

[0156] For example, the first wire passing portion 611 may pass through the bracket body 610 in an axial direction of the mounting bracket 600, and the second wire passing portion 634 may pass through the frame 631 of the filter mounting portion 630 in a radial direction of the mounting bracket 600, so that the wire harness 550 of the electric motor 500 may pass through the first wire passing portion 611 first, and therefore, the wire harness 550 may pass from one side of the bracket body 610 facing the electric motor 500 to the other side of the bracket body 610, and then, the wire harness 550 passes through the second wire passing portion 634, that is, the wire harness 550 may extend to the outside of the mounting bracket 600, so as to facilitate an electrical connection between the wire harness 550 and a power source. Furthermore, after the wire harness 550 passes through the first wire passing portion 611 and the second wire passing portion 634, the mounting bracket 600 may also restrain the wire harness 550, so that the wire harness 550 is routed in the ventilation assembly 200 more regularly and a layout is facilitated.

[0157] In some embodiments of the present disclosure, as shown in FIG. 26 to FIG. 29, the bracket body 610 is provided with a grid 612, and the grid 612 clears the electric motor mounting portion 620. The grid 612 is provided with hollowed portions 613, and at least one of the hollowed portions 613 is configured as the first wire passing portion 611. The hollowed portion 613 may be configured as a grid hole.

[0158] It may be appreciated that the hollowed portion 613 is generally configured to be small. In order to facilitate passing of the wire harness 550 of the electric motor 500, two or more adjacent hollowed portions 613 can be communicated to form the first wire passing portion 611, so that a diameter of the first wire passing portion 611 can be large, the wire harness 550 of the electric motor 500 can pass through the first wire passing portion 611 more easily, and assembly is more convenient.

[0159] In some embodiments of the present disclosure, as shown in FIG. 27 and FIG. 28, the bracket body 610 is provided with a limiting rib 614, and the limiting rib 614 is located on one side of the wire harness 550 to limit the wire harness 550. For example, the limiting rib 614 may be located between the first wire passing portion 611 and the second wire passing portion 634. In this way, when the wire harness 550 extends from the first wire passing portion 611 to the second wire passing portion 634, the limiting rib 614 can restrain the wire harness 550.

[0160] In some examples, a plurality of limiting ribs 614 may be provided. For example, two limiting ribs 614 may be provided. One limiting rib 614 is connected to the bracket body 610 and extends along the axial direction of the bracket body 610, and the wire harness 550 can be located between the limiting rib 614 and the electric motor mounting portion 620, so that the wire harness 550 can be limited by the limiting rib 614 and the electric motor mounting portion 620, and the wire harness 550 is prevented from shifting in the radial direction of the mounting bracket 600. In addition, the other limiting rib 614 may be connected to the side of the electric motor mounting portion 620 facing the exhaust filter portion 226, and the limiting rib 614 may extend in a direction perpendicular to the axial direction of the mounting bracket 600, so that the limiting rib may be stopped by the bracket on a side of the wire harness 550 facing away from the mounting bracket 600. In this way, the bracket body 610, the electric motor mounting portion 620 and the two limiting ribs 614 can be used to limit the wire harness 550 in a plurality of directions and prevent a position of the wire harness 550 from shifting, thereby preventing the position of the wire harness 550 from interfering with positions of other components in the ventilation assembly 200, and facilitating a layout.

[0161] As shown in FIG. 22 to FIG. 29, a cabinet air conditioner according to some embodiments of the present disclosure includes a cabinet 100, a heat exchanger, a heat exchange blower, and a ventilation assembly 200.

[0162] The cabinet 100 has an upper chamber and a lower chamber. The heat exchanger is arranged in the upper chamber, and the heat exchange blower is configured to deliver air subjected to heat exchange with the heat exchanger into a room. The ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into the room, and deliver indoor air to the room or the outside.

[0163] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, an electric motor 500, an exhaust filter portion 226, and a mounting bracket 600.

[0164] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. The exhaust filter portion 226 is arranged on an air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0165] The mounting bracket 600 is connected to the second air duct member 220, and the electric motor 500 and the exhaust filter portion 226 are mounted to the mounting bracket 600.

[0166] Thus, the cabinet 100 is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, the heat exchange blower is configured to deliver the air subjected to heat exchange with the heat exchanger into the room, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0167] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0168] Moreover, the electric motor 500 has the output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. Thus, the first fan 300 and the second fan 400 can share one electric motor 500, which is beneficial to reducing a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated. Moreover, the exhaust filter portion 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter portion 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving quality of the air entering the cabinet air conditioner, and can improve quality of outlet air of the air conditioner and prevent dust and impurities from entering the cabinet 100.

[0169] In addition, the mounting bracket 600 may be configured to mount both the electric motor 500 and the exhaust filter portion 226. That is, the electric motor 500 and the exhaust filter portion 226 may be mounted on one bracket. Thus, a number of the brackets can be reduced, an integration level of the mounting bracket 600 is higher, assembly is more convenient and faster, and an improvement of an assembly efficiency is facilitated.

[0170] It can be understood that, compared to the related art in which two brackets are provided to fix the electric motor 500 and the exhaust filter portion 226 respectively, in the cabinet air conditioner according to some embodiments of the present disclosure, one bracket may be omitted, thereby saving a set of molds for producing the bracket and facilitating a reduction of a production cost of the mounting bracket 600.

[0171] In the cabinet air conditioner according to some embodiments of the present disclosure, the electric motor 500 and the exhaust filter portion 226 can be simultaneously fixed by the mounting bracket 600, and the cabinet air conditioner has the advantages of a high integration level, convenient assembly, cost saving, or the like.

[0172] In some embodiments of the present disclosure, as shown in FIG. 24 and FIG. 26 to FIG. 29, a first wire passing portion 611 and a second wire passing portion 634 are arranged on the mounting bracket 600, the second wire passing portion 634 is located at an edge of the mounting bracket 600, and a wire harness 550 of the electric motor 500 sequentially passes through the first wire passing portion 611 and the second wire passing portion 634.

[0173] Thus, the wire harness 550 can pass out of the mounting bracket 600 through the second wire passing portion 634, so as to facilitate an electrical connection of the wire harness 550 and a power source, so that the electric motor 500 and the power source can be electrically conducted. Moreover, the wire harness 550 can be fixed through the first wire passing portion 611 and the second wire passing portion 634 of the mounting bracket 600, so that the wire harness 550 is routed in the ventilation assembly 200 more regularly and a layout is facilitated.

[0174] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0175] As shown in FIG. 30 to FIG. 39, a cabinet air conditioner according to some embodiments of the present disclosure includes a body, an adapting assembly 700 and a fresh air inlet pipe 730, and the body includes a cabinet 100, a heat exchanger and a fresh air blower.

[0176] The body includes an upper chamber and a lower chamber located below the upper chamber, a fifth air inlet 160 is formed in the cabinet 100, the heat exchanger is arranged in the upper chamber, and the fresh air blower is arranged in the lower chamber. The fresh air blower drives outdoor air to enter the lower chamber through the fifth air inlet 160. One end of the adapting assembly 700 is communicated with the fifth air inlet 160, the other end of the adapting assembly 700 is communicated with the fresh air inlet pipe 730, and the fresh air inlet pipe 730 and the fifth air inlet 160 are communicated by the adapting assembly 700.

[0177] The adapting assembly 700 includes a first adapter 710 and a second adapter 720, one end of the first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, two ends of the second adapter 720 are respectively connected with the other end of the first adapter 710 and the fresh air inlet pipe 730, and the second adapter 720 is rotatable relative to the first adapter 710 to adjust an included angle between a central axis of the first adapter 710 and a central axis of the second adapter 720.

[0178] The first adapter 710 may be in inserted connection with the cabinet 100 or may be connected thereto by a bolt. For example, the first adapter 710 may be provided with a mounting lug 716, the cabinet 100 may be provided with a bolt hole, and the mounting lug 716 of the first adapter 710 may be connected with the cabinet 100 by the bolt. The second adapter 720 and the fresh air inlet pipe 730 may be in inserted connection. For example, the second adapter 720 may be inserted into the fresh air inlet pipe 730 and in interference fit with the fresh air inlet pipe 730.

[0179] The second adapter 720 is rotatable relative to the first adapter 710, which means that the second adapter 720 can rotate relative to the first adapter 710 along the central axis thereof, or the first adapter 710 can rotate relative to the second adapter 720 along the central axis thereof.

[0180] In the cabinet air conditioner according to some embodiments of the present disclosure, the heat exchanger is arranged in the upper chamber, the fresh air blower is arranged in the lower chamber, the fresh air blower drives the outdoor air to enter the lower chamber from the fifth air inlet 160, one end of the adapting assembly 700 is communicated with the fifth air inlet 160, the other end of the adapting assembly 700 is communicated with the fresh air inlet pipe 730, and the fresh air inlet pipe 730 and the fifth air inlet 160 are communicated by the adapting assembly 700. Thus, the outdoor air may be guided to the fifth air inlet 160 through the fresh air inlet pipe 730 and flow into a room through the fifth air inlet 160 to purify indoor air.

[0181] In addition, the adapting assembly 700 includes the first adapter 710 and the second adapter 720, one end of the first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, and the two ends of the second adapter 720 are respectively connected with the other end of the first adapter 710 and the fresh air inlet pipe 730. Moreover, the second adapter 720 is rotatable relative to the first adapter 710 to adjust the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720.

[0182] In this way, an included angle between the first adapter 710 and the second adapter 720 can be adjusted according to a mounting position of the cabinet air conditioner. That is, by relatively rotating the first adapter 710 and the second adapter 720, an included angle between a central axis of the fresh air inlet pipe 730 and a central axis of the fifth air inlet 160 can be adjusted.

[0183] For example, as shown in FIG. 30, when the fifth air inlet 160 directly faces a wall 740, the first adapter 710 and the second adapter 720 may be relatively rotated to cause the central axis of the first adapter 710 to coincide with the central axis of the second adapter 720. That is, the adapting assembly 700 is linear. Thus, it facilitates the fresh air inlet pipe 730 to pass through the wall 740 to be connected with the fifth air inlet 160 through the adapting assembly 700, and is conducive to reducing an occupied space of the adapting assembly 700. The adapting assembly 700 is not bent, so that an air flow resistance in the adapting assembly 700 is smaller, and the outdoor air can flow more smoothly to the fifth air inlet 160 through the fresh air inlet pipe 730 and the adapting assembly 700, thereby facilitating outdoor fresh air to be introduced into the room.

[0184] When the fifth air inlet 160 is tilted relative to the wall 740, for example, as shown in FIG. 38, the fifth air inlet 160 faces a corner of the wall 740 (that is, when the fresh air inlet pipe 730 is tilted relative to the central axis of the fifth air inlet 160), the first adapter 710 and the second adapter 720 can be relatively rotated to make the adapting assembly 700 have a bent shape. In this way, the central axis of the first adapter 710 may coincide with the central axis of the fifth air inlet 160, so as to facilitate the first adapter 710 to be connected with the cabinet 100 and communicated with the fifth air inlet 160, and the central axis of the second adapter 720 may coincide with the central axis of the fresh air inlet pipe 730, so as to facilitate the second adapter 720 to be connected with the fresh air inlet pipe 730, so that mounting is more convenient and faster, and the occupied space of the adapting assembly 700 may be smaller, which is beneficial to reducing a space required for mounting the cabinet air conditioner.

[0185] Therefore, when the cabinet air conditioner is mounted at different positions, and the fifth air inlet 160 directly faces the wall 740 or is inclined relative to the wall 740, the adapting assembly 700 can be adjusted according to the mounting position of the cabinet air conditioner, so as to change the included angle between the first adapter 710 and the second adapter 720, so that the adapting assembly 700 can adapt to mounting at multiple angles, the connection between the fresh air inlet pipe 730, the adapting assembly 700 and the cabinet 100 is more convenient, the mounting space of the cabinet air conditioner can be saved, and mounting is facilitated.

[0186] Therefore, the cabinet air conditioner according to some embodiments of the present disclosure can meet requirements of different mounting environments, and has the advantages of a high mounting efficiency, convenient mounting, a small mounting space, or the like.

[0187] In some embodiments of the present disclosure, as shown in FIG. 34, one of the first adapter 710 and the second adapter 720 is provided with a second engaging structure 721, the other is provided with a first engaging structure 711, and the second engaging structure 721 is rotatably engaged in the first engaging structure 711. The first engaging structure 711 may be an engaging ring groove, and the second engaging structure 721 may be an engaging ring platform.

[0188] For example, an end of the first adapter 710 facing the second adapter 720 may be provided with the first engaging structure 711, and an end of the second adapter 720 facing the first adapter 710 may be provided with the second engaging structure 721. By engagement of the first engaging structure 711 and the second engaging structure 721, a connection structure is simple, the connection of the first adapter 710 and the second adapter 720 is easy to realize, and the second engaging structure 721 can rotate in the first engaging structure 711, so that the first adapter 710 and the second adapter 720 can rotate relatively, and the first adapter 710 and the second adapter 720 are not prone to separation during the relative rotation.

[0189] Further, as shown in FIG. 32 to FIG. 37, an outer contour of the second engaging structure 721 and an inner contour of the first engaging structure 711 are configured as matched circles.

[0190] Therefore, when the second engaging structure 721 rotates to any angle relative to the first engaging structure 711, an outer circumferential surface of the second engaging structure 721 and an inner circumferential surface of the first engaging structure 711 can be attached, so that the second engaging structure 721 can be stably engaged in the first engaging structure 711, the inner circumferential surface of the first engaging structure 711 and the second engaging structure 721 can be prevented from rotating and interfering with each other, and therefore, the relative rotation of the first adapter 710 and the second adapter 720 is easier.

[0191] In some embodiments of the present disclosure, as shown in FIG. 36 and FIG. 37, a central axis of the second engaging structure 721 and the central axis of one of the first adapter 710 and the second adapter 720 form a first inclination angle, and a central axis of the first engaging structure 711 and the central axis of the other of the first adapter 710 and the second adapter 720 form a second inclination angle. A difference between the first inclination angle and the second inclination angle is A, and A satisfies the following condition: -10°≤A≤10°.

[0192] For example, the first engaging structure 711 may be arranged on the first adapter 710, and the second engaging structure 721 may be arranged on the second adapter 720. As shown in FIG. 36, an included angle between the central axis of the first adapter 710 and the central axis of the first engaging structure 711 is C, that is, the second inclination angle is C; as shown in FIG. 37, an included angle between the central axis of the second adapter 720 and the central axis of the second engaging structure 721 is B, that is, the first inclination angle is B.

[0193] The first inclination angle may be equal to the second inclination angle. In this way, by enabling the first adapter 710 and the second adapter 720 to rotate relatively, the central axis of the first adapter 710 and the central axis of the second adapter 720 can coincide with each other. That is, when the first adapter 710 and the second adapter 720 are rotated to extreme positions, the adapting assembly 700 may be linear, so that the fresh air inlet pipe 730 and the fifth air inlet 160 are connected through the adapting assembly 700 under the condition that the fresh air inlet pipe 730 directly faces the fifth air inlet 160.

[0194] Certainly, there may be a difference between the first inclination angle and the second inclination angle. For example, the first inclination angle may be greater than the second inclination angle, and the difference between the first inclination angle and the second inclination angle is 0° to 10°. Alternatively, the first inclination angle may be less than the second inclination angle, and the difference between the first inclination angle and the second inclination angle is -10° to 0°.

[0195] Therefore, a pressing force can exist between the second engaging structure 721 and the first engaging structure 711, which is beneficial to improving a sealing performance between the second engaging structure 721 and the first engaging structure 711. Moreover, the difference between the first inclination angle and the second inclination angle is not too large, so as to avoid that a bending angle between the first adapter 710 and the second adapter 720 is too small during the relative rotation of the first adapter 710 and the second adapter 720, and then ensure that the air flow resistance in the adapting assembly 700 is small, and the outdoor air flows in the adapting assembly 700 more smoothly.

[0196] It may be appreciated that the second engaging structure 721 and the first engaging structure 711 always remain engaged when the first adapter 710 and the second adapter 720 rotate relatively. That is, it can be considered to indicate that the first adapter 710 rotates relative to the second adapter 720 along the central axis of the first engaging structure 711, or the second adapter 720 rotates relative to the first adapter 710 along the central axis of the second engaging structure 721, so that the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 can be adjusted to adjust the adapting assembly 700 to be linear or bent, and the bending angle of the adapting assembly 700 can be adjusted according to the mounting position of the cabinet air conditioner.

[0197] In some embodiments of the present disclosure, as shown in FIG. 35, the first engaging structure 711 includes an abutting portion 712, a body portion 713, and an engaging portion 714.

[0198] A plane of the abutting portion 712 is perpendicular to the central axis of the first engaging structure 711, and the second engaging structure 721 abuts against the abutting portion 712. The body portion 713 is connected to the abutting portion 712 and surrounds the second engaging structure 721, and the engaging portion 714 is connected to the body portion 713 and protrudes from an inner circumferential surface of the body portion 713. The second engaging structure 721 is engaged between the abutting portion 712 and the engaging portion 714.

[0199] Therefore, when the second engaging structure 721 is inserted into the first engaging structure 711, an end of the second engaging structure 721 facing the first engaging structure 711 can abut against the abutting portion 712. The abutting portion 712 can limit an insertion position of the second engaging structure 721 to prevent an inserted connection size of the first adapter 710 and the second adapter 720 from being too large, and the engaging portion 714 can be engaged on a side of the second engaging structure 721 facing away from the abutting portion 712, so that the position of the second engaging structure 721 can be fixed by the engaging portion 714 and the abutting portion 712, the first adapter 710 and the second adapter 720 can be connected more stably, and the first adapter 710 and the second adapter 720 are prevented from being separated.

[0200] Moreover, the body portion 713 may surround the second engaging structure 721 from the outer circumferential surface of the second engaging structure 721. On the one hand, a contact area of the second engaging structure 721 and the first engaging structure 711 can be increased, so that connection strength of the second engaging structure 721 and the first engaging structure 711 is higher, and the connection between the first adapter 710 and the second adapter 720 is more stable and reliable. On the other hand, the second engaging structure 721 can be limited in a radial direction by the body portion 713, so that radial dislocation of the first adapter 710 and the second adapter 720 can be avoided, and a structure arrangement is more reasonable.

[0201] In some embodiments of the present disclosure, as shown in FIG. 35, the engaging portions 714 are a plurality of latches 632, and the plurality of latches 632 are arranged at intervals along a circumference of the body portion 713.

[0202] For example, the plurality of latches 632 are arranged at an end of the body portion 713 away from the abutting portion 712, and the latches 632 protrude from an inner circumferential surface of the body portion 713. Thus, after the second engaging structure 721 is inserted into the first engaging structure 711, the plurality of latches 632 can abut against the second engaging structure 721 at a plurality of positions along a circumference of the second engaging structure 721, so that the second engaging structure 721 is prevented from being separated from the first engaging structure 711, and then, the first adapter 710 and the second adapter 720 can be prevented from being separated from each other.

[0203] In addition, by providing the plurality of latches 632, connection stability of the first engaging structure 711 and the second engaging structure 721 can be improved, and the second engaging structure 721 is engaged by the plurality of latches 632 simultaneously, so that connection failure of the first engaging structure 711 and the second engaging structure 721 caused by connection failure of a single latch 632 can be avoided, and connection reliability of the first adapter 710 and the second adapter 720 is further improved.

[0204] In some embodiments of the present disclosure, as shown in FIG. 35, the body portion 713 is provided with a plurality of deformation portions 715, and the plurality of deformation portions 715 are respectively arranged on two opposite sides of the latches 632.

[0205] The arrangement of the deformation portion 715 can weaken structural strength of the body portion 713 on the two sides of the latch 632, so that when the second engaging structure 721 is inserted into the first engaging structure 711, the latch 632 can be elastically deformed more easily, and therefore, the first adapter 710 and the second adapter 720 can be mounted more easily, the mounting is more convenient and faster, and the engaging portion 714 and the second engaging structure 721 can be prevented from being damaged in the mounting process.

[0206] In some embodiments of the present disclosure, the second adapter 720 has a first position and a second position. When the second adapter 720 is located at the first position, the central axis of the second adapter 720 coincides with the central axis of the first adapter 710. When the second adapter 720 is located at the second position, the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is α, and α satisfies the following condition: 90°≤α≤135°.

[0207] That is, the relative rotation of the second adapter 720 and the first adapter 710 have two extreme positions. When the second adapter 720 is located at the first position, that is, the second adapter 720 and the first adapter 710 relatively rotate to the first extreme position, the adapting assembly 700 may be linear. When the second adapter 720 is located at the second position, that is, the second adapter 720 and the first adapter 710 relatively rotate to the second extreme position, the adapting assembly 700 may be bent, and the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is between 90° and 135°. Thus, the second adapter 720 can rotate between the first position and the second position, so that the bending angle of the adapting assembly 700 can be adjusted.

[0208] Moreover, since 90°≤α≤135°, the first adapter 710 and the second adapter 720 can rotate relatively according to the mounting position of the cabinet air conditioner, so that the included angle between the first adapter 710 and the second adapter 720 can be proper by rotation, and the adapting assembly 700 can be conveniently connected with the fresh air inlet pipe 730 and the cabinet 100 respectively.

[0209] In some other embodiments of the present disclosure, as shown in FIG. 30 to FIG. 39, the adapting assembly 700 includes a first adapter 710 and a second adapter 720.

[0210] The first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, the second adapter 720 is connected with the fresh air inlet pipe 730, and an extending direction of the second adapter 720 is adjustable relative to an extending direction of the first adapter 710.

[0211] Thus, when the fifth air inlet 160 directly faces the wall 740, the central axis of the fresh air inlet pipe 730 may coincide with the central axis of the fifth air inlet 160, and in this case, the extending direction of the first adapter 710 and the extending direction of the second adapter 720 may be adjusted to extend in a same direction. That is, the adapting assembly 700 may be linear, so as to facilitate the connection between the first adapter 710 and the cabinet 100 and the connection between the second adapter 720 and the fresh air inlet pipe 730.

[0212] When the fifth air inlet 160 obliquely faces the wall 740, the central axis of the fresh air inlet pipe 730 may be inclined relative to the central axis of the fifth air inlet 160. In this case, the extending direction of the first adapter 710 and the extending direction of the second adapter 720 may be adjusted to be relatively inclined. That is, the adapting assembly 700 may be bent, so that the extending direction of the first adapter 710 may coincide with the central axis of the fifth air inlet 160, and the extending direction of the second adapter 720 may coincide with the central axis of the fresh air inlet pipe, which facilitates the connection between the first adapter 710 and the cabinet 100 and the connection between the second adapter 720 and the fresh air inlet pipe 730, and is beneficial to reducing the occupied space of the adapting assembly 700, so that the mounting space of the cabinet air conditioner may be smaller.

[0213] The cabinet air conditioner according to some embodiments of the present disclosure can meet requirements of different mounting environments, and has the advantages of a high mounting efficiency, convenient mounting, a small mounting space, or the like.

[0214] In some embodiments of the present disclosure, the first adapter 710 is provided with a second engaging structure 721, the central axis of the first adapter 710 is perpendicular to a first section, a central axis of the second engaging structure 721 is perpendicular to a second section, an included angle between the first section and the second section is β, and β satisfies the following condition: 10°≤β≤45°.

[0215] In this way, there may be an angular difference between the central axis of the first adapter 710 and the central axis of the second engaging structure 721, and when the second engaging structure 721 rotates relative to the second adapter 720, the first adapter 710 may be driven to rotate. The first adapter 710 may be bent in different directions relative to the second adapter 720, so that an angular difference between the first adapter 710 and the second adapter 720 may be adjusted to enable the first adapter 710 and the second adapter 720 to form a linear shape or a bent shape with different angles.

[0216] Moreover, since 10°≤β≤45°, on the one hand, the included angle between the first section and the second section can be prevented from being too small, so that the included angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721 can be large, and during the rotation of the second engaging structure 721 relative to the second adapter 720, a change range of the included angle between the first adapter 710 and the second adapter 720 can be large, so as to adjust the shape of the adapting assembly 700 to enable the cabinet air conditioner to satisfy requirements of different mounting environments. On the other hand, the included angle between the first section and the second section can be prevented from being too large, so that it can be avoided that during rotation of the second engaging structure 721 relative to the second adapter 720, the first adapter 710 is excessively bent relative to the second adapter 720, air flow in the adapting assembly 700 can be kept smooth, and it can be avoided that structural strength of the first adapter 710 and the second engaging structure 721 is lowered due to the excessively large included angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721, so as to ensure that overall structural strength of the adapting assembly 700 may be high.

[0217] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0218] As shown in FIG. 40 to FIG. 51, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, and a ventilation assembly 200.

[0219] The body has an upper chamber and a lower chamber located below the upper chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into a room, and deliver indoor air to the room or the outside.

[0220] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0221] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside. The second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510.

[0222] One of the first fan 300 and the second fan 400 is provided with a first rotation stopping portion 320, the other is provided with a second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at a same frequency.

[0223] In the cabinet air conditioner according to some embodiments of the present disclosure, the body is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0224] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside. The second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0225] Moreover, the electric motor 500 has the single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated.

[0226] In addition, one of the first fan 300 and the second fan 400 is provided with the first rotation stopping portion 320, the other is provided with the second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0227] It should be noted that the first rotation stopping portion 320 fits the second rotation stopping portion 420 to stop rotation of the second fan 400 and the first fan 300 in a circumferential direction of the output shaft 510. That is, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Moreover, the first rotation stopping portion 320 fits the second rotation stopping portion 420 to position the assembly of the second fan 400 and the first fan 300.

[0228] Therefore, even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first rotation stopping portion 320 fits the second rotation stopping portion 420, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and the rotation speed of the second fan 400 is lower than that of the first fan 300. After the first rotation stopping portion 320 fits the second rotation stopping portion 420, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0229] Thus, in the cabinet air conditioner according to some embodiments of the present disclosure, the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the vibration and noise and improving the use effect of the air conditioner.

[0230] In some embodiments of the present disclosure, as shown in FIG. 44 and FIG. 45, a side of the first fan 300 facing the second fan 400 is provided with a first hub 330, and the first hub 330 protrudes towards the second fan 400 to form a first fitting portion 340.

[0231] As shown in FIG. 47 and FIG. 48, a second hub 430 is arranged on a side of the second fan 400 facing the first fan 300, and the second hub 430 is recessed towards the first fan 300 to form a second fitting portion 440. One of the first fitting portion 340 and the second fitting portion 440 is provided with the first rotation stopping portion 320, and the other is provided with the second rotation stopping portion 420.

[0232] That is, the first fitting portion 340 may be provided with the first rotation stopping portion 320, and the second fitting portion 440 may be provided with the second rotation stopping portion 420; alternatively, the first fitting portion 340 may be provided with the second rotation stopping portion 420, and the second fitting portion 440 may be provided with the first rotation stopping portion 320.

[0233] By causing the first fitting portion 340 to protrude towards the second fan 400 and recessing the second fitting portion 440 towards the first fan 300, the first fitting portion 340 and the second fitting portion 440 can be closer to each other, so that the first fitting portion 340 and the second fitting portion 440 can be conveniently in contact fit, the first rotation stopping portion 320 and the second rotation stopping portion 420 can be stably and reliably fitted together, the first rotation stopping portion 320 and the second rotation stopping portion 420 are prevented from being separated, and then, the second fan 400 and the first fan 300 can be ensured to rotate at the same frequency, so as to reduce the vibration and noise of the cabinet air conditioner.

[0234] Further, as shown in FIG. 46 and FIG. 49, the first rotation stopping portions 320 are a plurality of rotation stopping protrusions, the plurality of rotation stopping protrusions are arranged along a circumferential direction of the first fitting portion 340, the second rotation stopping portions 420 are a plurality of rotation stopping grooves, the plurality of rotation stopping grooves are arranged along a circumferential direction of the second fitting portion 440, and the plurality of rotation stopping protrusions are inserted into the plurality of rotation stopping grooves in a one-to-one correspondence manner.

[0235] By providing the plural rotation stopping protrusions and the plural rotation stopping grooves, the rotation stopping protrusions and the rotation stopping grooves can be fitted more stably and reliably, connection failure of the second fan 400 and the first fan 300 is avoided, rotation synchronism of the second fan 400 and the first fan 300 is effectively guaranteed, rotation noise and rotation vibration of the second fan 400 and the first fan 300 are smaller, and the use effect of the air conditioner is improved.

[0236] Further, the first rotation stopping portion 320 and the second rotation stopping portion 420 are configured as the protrusion and the groove fitting each other, which is conducive to simplifying structures of the first rotation stopping portion 320 and the second rotation stopping portion 420 to facilitate processing and manufacturing, and can simplify assembly of the second fan 400 and the first fan 300, and when the second fan 400 and the first fan 300 are assembled in place along a circumferential direction of the output shaft 510, the rotation stopping protrusion can be inserted into the rotation stopping groove, resulting in a higher assembly efficiency.

[0237] It can be understood that the first rotation stopping portion 320 and the second rotation stopping portion 420 may have other fitting structures. For example, the first rotation stopping portion 320 and the second rotation stopping portion 420 can be configured as protrusions, and the protrusions on the first fitting portion 340 and the protrusions on the second fitting portion 440 are staggered in a circumferential direction, so that the protrusions on the first fitting portion 340 and the protrusions on the second fitting portion 440 can abut against each other, and thus, the two fans can rotate at the same frequency.

[0238] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, the rotation stopping protrusion has a first side 321 and a second side 322 opposite to each other in the circumferential direction of the first fitting portion 340, and the first side 321 and the second side 322 get close to each other along an axial direction of the first fitting portion 340 towards the rotation stopping groove. The rotation stopping groove has a first wall 421 and a second wall 422 opposite to each other in the circumferential direction of the second fitting portion 440, and away from the rotation stopping protrusion in an axial direction of the second fitting portion 440, the first wall 421 and the second wall 422 are close to each other.

[0239] That is, the first side 321 and the second side 322 may be configured as slopes, and the first wall 421 and the second wall 422 may also be configured as slopes. It should be noted that an inclination angle of the first side 321 and an inclination angle of the first wall 421 may be the same, and an inclination angle of the second side 322 and an inclination angle of the second wall 422 may be the same.

[0240] Thus, after the rotation stopping protrusion is inserted into the rotation stopping groove, the first side 321 and the second wall 422 can abut against each other and have a large contact area, and the second side 322 and the second wall 422 can abut against each other and have a large contact area. Thus, attachment of the rotation stopping protrusion and the rotation stopping groove can be tighter, fitting stability of the rotation stopping protrusion and the rotation stopping groove is further improved, the second fan 400 and the first fan 300 are ensured not to rotate or shake relatively, and the vibration and rotation noise of the second fan 400 and the first fan 300 are more effectively reduced.

[0241] Furthermore, with this arrangement, a width of an end of the rotation stopping protrusion away from the first fitting portion 340 may be small, and an opening width of the rotation stopping groove may be large, so as to facilitate the insertion of the rotation stopping protrusion into the rotation stopping groove. That is, the rotation stopping protrusion and the rotation stopping groove can guide the assembly of the second fan 400 and the first fan 300, which is conducive to simplifying the assembly of the second fan 400 and the first fan 300, and an assembly efficiency is higher.

[0242] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, the first side 321 and the second side 322 get away from each other in a radial direction of the first fitting portion 340 outwards. The first wall 421 and the second wall 422 get away from each other in a radial direction of the second fitting portion 440 outwards.

[0243] It can be understood that, in the radial direction of the first fitting portion 340, the closer to a central axis of the first fitting portion 340, the smaller a radius of the first fitting portion 340, the smaller a space for arranging the rotation stopping protrusion in the circumferential direction. In the radial direction of the first fitting portion 340 outwards, the radius of the first fitting portion 340 is increased, the space for arranging the rotation stopping protrusion in the circumferential direction is also increased, and a distance between the first side 321 and the second side 322 is increased. Thus, the rotation stopping protrusions can make full use of the space on the first fitting portion 340, and the adjacent rotation stopping protrusions can be prevented from being too close to each other, so that a layout is more reasonable.

[0244] Similarly, in the radial direction of the second fitting portion 440, the closer to a central axis of the second fitting portion 440, the smaller a radius of the second fitting portion 440, the smaller a space for arranging the rotation stopping groove in the circumferential direction. In the radial direction of the second fitting portion 440 outwards, the radius of the second fitting portion 440 is increased, the space for arranging the rotation stopping groove in the circumferential direction is also increased, and a distance between the first wall 421 and the second wall 422 is increased. Thus, the rotation stopping grooves can make full use of the space on the second fitting portion 440, and the adjacent rotation stopping grooves can be prevented from being too close to each other, so that a layout is more reasonable.

[0245] Moreover, the first side 321 and the second side 322 may also be configured as slopes in the radial direction of the first fitting portion 340, and the first wall 421 and the second wall 422 may also be configured as slopes in the radial direction of the second fitting portion 440. Thus, a contact area of the first side 321 and the first wall 421 is further increased, a contact area of the second side 322 and the second wall 422 is further increased, the rotation stopping protrusion and the rotation stopping groove are more closely fitted, and connection stability of the first fan 300 and the second fan 400 is higher.

[0246] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, a side of the rotation stopping protrusion away from a center of the first fitting portion 340 is configured as a third side 323, and the third side 323 is inclined towards the center of the first fitting portion 340 towards the rotation stopping groove in the axial direction of the first fitting portion 340. A side of the rotation stopping groove away from a center of the second fitting portion 440 is configured as a third wall 423, and away from the rotation stopping protrusion in the axial direction of the second fitting portion 440, the third wall 423 is inclined towards the center of the second fitting portion 440.

[0247] That is, the third side 323 may be configured as a slope, and the third wall 423 may be configured as a slope. Thus, a contact area of the third side 323 and the third wall 423 is also large. After the rotation stopping protrusion is inserted into the rotation stopping groove, the third side 323 and the third wall 423 can abut against each other, attachment of the rotation stopping protrusion and the rotation stopping groove can be tighter, the fitting stability of the rotation stopping protrusion and the rotation stopping groove is further improved, the second fan 400 and the first fan 300 are ensured not to rotate or shake relatively, and the vibration and rotation noise of the second fan 400 and the first fan 300 are more effectively reduced.

[0248] Moreover, the third side 323 fits the third wall 423 to guide the fitting of the rotation stopping protrusion and the rotation stopping groove, so as to guide the assembly of the second fan 400 and the first fan 300, which is beneficial to simplifying the assembly of the second fan 400 and the first fan 300, resulting in the higher assembly efficiency.

[0249] In some embodiments of the present disclosure, as shown in FIG. 50 and FIG. 51, the first fan 300 further includes a first insert 350. The first insert 350 is fixed in the first hub 330, and the output shaft 510 is sleeved with the first insert 350 which is in transmission connection with the output shaft 510. The second fan 400 further includes a second insert 450, the second insert 450 is fixed in the second hub 430, and the output shaft 510 is sleeved with the second insert 450 which is in transmission connection with the output shaft 510.

[0250] The first insert 350 may be molded by injection and arranged within the first hub 330, and hardness of the first insert 350 may be greater than hardness of the first hub 330. Thus, fitting stability of the first fan 300 and the output shaft 510 can be improved, a gap between the first insert 350 and the output shaft 510 can be small, and the output shaft 510 can more stably drive the first fan 300 to rotate. In addition, the second insert 450 may be molded by injection and arranged in the second hub 430, and hardness of the second insert 450 may be greater than that of the second hub 430, so that fitting stability of the second fan 400 and the output shaft 510 may be improved, a gap between the second insert 450 and the output shaft 510 may be small, and the output shaft 510 may more stably drive the second fan 400 to rotate.

[0251] Further, as shown in FIG. 51, an outer contour of the output shaft 510 is non-circular, the first insert 350 is provided with a first rotation preventing portion 351 adapted to the outer contour of the output shaft 510, the second insert 450 is provided with a second rotation preventing portion 451 adapted to the outer contour of the output shaft 510, and the output shaft 510 is arranged through the first rotation preventing portion 351 and the second rotation preventing portion 451.

[0252] The first rotation preventing portion 351 may be configured as a first rotation stopping hole, and the second rotation preventing portion 451 may be configured as a second rotation stopping hole.

[0253] Thus, after the output shaft 510 is arranged through the first rotation preventing portion 351, the output shaft 510 and the first insert 350 do not rotate relative to each other. That is, the output shaft 510 and the first fan 300 do not rotate relative to each other, so that the first fan 300 can be driven to rotate by the output shaft 510.

[0254] Moreover, after the output shaft 510 is arranged through the second rotation preventing portion 451, the output shaft 510 and the second insert 450 also do not rotate relative to each other. That is, the output shaft 510 and the second fan 400 do not rotate relative to each other, so that the second fan 400 can be driven to rotate by the output shaft 510.

[0255] It can be understood that, for the convenience of assembly, a certain gap may exist between the output shaft 510 and the first rotation preventing portion 351, a certain gap may exist between the output shaft 510 and the second rotation preventing portion 451, and when the output shaft 510 drives the first fan 300 and the second fan 400 to rotate, the first fan 300 and the second fan 400 may shake relatively, and in some embodiments of the present disclosure, after the second fan 400 and the first fan 300 are connected and positioned by the first rotation stopping portion 320 and the second rotation stopping portion 420, the second fan 400 and the first fan 300 may not rotate relatively or a relative rotation amplitude is small, so that rotation noise and rotation vibration of the second fan 400 and the first fan 300 may be reduced, and the use effect of the air conditioner may be improved.

[0256] As shown in FIG. 40 to FIG. 51, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, and a ventilation assembly 200.

[0257] The body has an upper chamber and a lower chamber located below the upper chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into a room, and deliver indoor air to the room or the outside.

[0258] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0259] For example, the body is provided with the upper chamber and the lower chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0260] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0261] Moreover, the electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated.

[0262] In addition, the first fan 300 and the second fan 400 are connected to rotate at a same frequency.

[0263] Therefore, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first fan 300 and the second fan 400 are connected, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and in this case, the rotation speed of the second fan 400 is lower than that of the first fan 300, and after the first fan 300 and the second fan 400 are connected, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds. The first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0264] In the cabinet air conditioner according to some embodiments of the present disclosure, the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the vibration and noise and improving the use effect of the air conditioner.

[0265] In some embodiments of the present disclosure, as shown in FIG. 42, FIG. 46 and FIG. 49, a rotation stopping protrusion is arranged on a side of the first fan 300 facing the second fan 400, a rotation stopping groove is formed in a side of the second fan 400 facing the first fan 300, and the rotation stopping protrusion is inserted into the rotation stopping groove.

[0266] The connection of the first fan 300 and the second fan 400 is configured as fitting of the protrusion and the groove, which is conducive to simplifying a connection structure of the first fan 300 and the second fan 400 to facilitate processing and manufacturing, and can simplify the assembly of the second fan 400 and the first fan 300. When the second fan 400 and the first fan 300 are assembled in place along a circumferential direction of the output shaft 510, the rotation stopping protrusion can be inserted into the rotation stopping groove, the first fan 300 and the second fan 400 are connected, and an assembly efficiency of the first fan 300 and the second fan 400 is higher.

[0267] Moreover, after the rotation stopping protrusion is inserted into the rotation stopping groove, a side of the rotation stopping protrusion can abut against a wall of the rotation stopping groove, and the rotation stopping protrusion and the rotation stopping groove cannot rotate relatively, so that the same-frequency rotation of the first fan 300 and the second fan 400 can be realized.

[0268] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0269] As shown in FIG. 52 to FIG. 58, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0270] The heat exchanger is arranged in an upper chamber, the first air duct member 210 is arranged in a lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor air enters a room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, so as to drive the first fan 300 and the second fan 400 to rotate synchronously.

[0271] One of the first air duct member 210 and the second air duct member 220 is provided with an air duct member fixing portion 227, and a free end of the output shaft 510 is rotatably mounted to the air duct member fixing portion 227.

[0272] Lubricating oil may be applied to a joint between the free end of the output shaft 510 and the air duct member fixing portion 227 to make the output shaft 510 rotate more easily and reduce noise of the output shaft 510 during rotation.

[0273] In the cabinet air conditioner according to some embodiments of the present disclosure, the body is provided with the upper chamber and the lower chamber, and the heat exchanger is arranged in the upper chamber. The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room.

[0274] Thus, the second fan 400 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the first fan 300 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the first fan 300 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0275] Meanwhile, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0276] The electric motor 500 has the single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, so as to drive the first fan 300 and the second fan 400 to rotate synchronously. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the cabinet air conditioner is facilitated.

[0277] In addition, one of the first air duct member 210 and the second air duct member 220 is provided with the air duct member fixing portion 227, and the free end of the output shaft 510 is rotatably mounted to the air duct member fixing portion 227.

[0278] For example, the electric motor 500 may be arranged in the first air duct member 210, and the output shaft 510 of the electric motor 500 extends towards the second air duct member 220. In this case, the second air duct member 220 may be provided with the air duct member fixing portion 227, and an end of the output shaft 510 away from the electric motor 500 (i.e., the free end of the output shaft 510) may be mounted on the air duct member fixing portion 227 of the second air duct member 220. Alternatively, the electric motor 500 may be arranged in the second air duct member 220, and the output shaft 510 of the electric motor 500 extends towards the first air duct member 210. In this case, the first air duct member 210 may be provided with the air duct member fixing portion 227, and the end of the output shaft 510 away from the electric motor 500 (i.e., the free end of the output shaft 510) may be mounted on the air duct member fixing portion 227 of the first air duct member 210. In this way, a structure of the first air duct member 210 and a structure of the second air duct member 220 may be configured according to a layout of the electric motor 500, so as to ensure that the free end of the output shaft 510 can be mounted on the air duct member fixing portion 227, and prevent a position of the air duct member fixing portion 227 from interfering with a position of the electric motor 500 or another component.

[0279] Furthermore, by connecting the free end of the output shaft 510 with the air duct member fixing portion 227, the free end of the output shaft 510 can be fixedly connected with the first air duct member 210 or the second air duct member 220, and the first air duct member 210 or the second air duct member 220 can support the free end of the output shaft 510, thereby improving rotation stability of the output shaft 510. The output shaft 510 is not prone to shake, so that vibration of the output shaft 510 during rotation and noise generated by the vibration can be greatly reduced, vibration and noise during operation of the cabinet air conditioner are smaller, and a use effect of the air conditioner is improved.

[0280] In this way, in the cabinet air conditioner according to some embodiments of the present disclosure, support of the output shaft 510 of the electric motor 500 can be enhanced, the rotation of the output shaft 510 is more stable, and the vibration and rotation noise are smaller, thereby improving the use effect of the air conditioner.

[0281] In some embodiments of the present disclosure, as shown in FIG. 53, the air duct member fixing portion 227 extends in an axial direction of one of the first fan 300 and the second fan 400, and the air duct member fixing portion 227 is provided to protrude towards the output shaft 510.

[0282] For example, the first air duct member 210 is provided with the air duct member fixing portion 227, and the air duct member fixing portion 227 extends in the axial direction of the first fan 300. If the second air duct member 220 is provided with the air duct member fixing portion 227, the air duct member fixing portion 227 extends along the axial direction of the second fan 400. This arrangement facilitates the free end of the output shaft 510 to be mounted on the air duct member fixing portion 227, assembly is more convenient, and a blocking area of the air duct member fixing portion 227 in a radial direction of the first air duct member 210 or the second air duct member 220 may be small, so that the air duct member fixing portion 227 can be prevented from excessively blocking an air inlet, so as to facilitate the indoor air to enter the first air duct member 210, or facilitate the outdoor fresh air to enter the second air duct member 220.

[0283] In addition, the air duct member fixing portion 227 protrudes towards the output shaft 510, that is, the air duct member fixing portion 227 protrudes from the first air duct member 210 or the second air duct member 220. Thus, the air duct member fixing portion 227 may be closer to the free end of the output shaft 510, so as to facilitate the output shaft 510 to be inserted into the air duct member fixing portion 227, and assembly is more convenient.

[0284] In some embodiments of the present disclosure, as shown in FIG. 53, a central axis of the air duct member fixing portion 227 and a central axis of the output shaft 510 coincide. Thus, the air duct member fixing portion 227 and the output shaft 510 may coincide, and the free end of the output shaft 510 may be inserted into the air duct member fixing portion 227 to support the output shaft 510 through the air duct member fixing portion 227, so that rotation of the output shaft 510 is more stable. Moreover, the air duct member fixing portion 227 and the output shaft 510 are not staggered in a radial direction of the output shaft 510, which can simplify assembly of the output shaft 510 and the air duct member fixing portion 227, and can reduce a space occupied by the output shaft 510 and the air duct member fixing portion 227 in the radial direction of the first air duct member 210 or the second air duct member 220, thereby facilitating a layout and avoiding position interference of components.

[0285] In addition, in some embodiments, as shown in FIG. 53, an outer diameter of the air duct member fixing portion 227 may be reduced towards the output shaft 510 in an axial direction of the air duct member fixing portion 227. Thus, an outer diameter of a joint of the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 may be large, connection strength of the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 is higher, stability of the air duct member fixing portion 227 is better, and the air duct member fixing portion 227 is not prone to shake. Thus, the air duct member fixing portion 227 can more reliably support the free end of the output shaft 510, so that the rotation of the output shaft 510 can be more stable, the rotation vibration and noise of the output shaft 510 can be small, and the use effect of the air conditioner can be improved.

[0286] In some embodiments of the present disclosure, as shown in FIG. 57, the output shaft 510 includes a transmission section 511, an output shaft fixing section 512, and a support section 513. The output shaft fixing portion 512 may be a threaded section.

[0287] The transmission section 511 is sleeved with the first fan 300 and the second fan 400 which are in transmission connection with the transmission section 511, one end of the output shaft fixing portion 512 is connected with the transmission section 511, and a fastener 520 is arranged on the output shaft fixing portion 512. The first fan 300 and the second fan 400 are stopped between the electric motor 500 and the fastener 520, the support section 513 is connected with the other end of the output shaft fixing portion 512, and the support section 513 is rotatably inserted into the air duct member fixing portion 227.

[0288] An outer contour of the transmission section 511 may be configured to be non-circular, so that after the transmission section 511 is sleeved with the first fan 300 and the second fan 400, the transmission section 511 can drive the second fan 400 and the first fan 300 to rotate.

[0289] Additionally, the fastener 520 may be a nut. After the transmission section 511 is sleeved with the first fan 300 and the second fan 400, the nut can be in screwed connection with the output shaft fixing portion 512, so that the first fan 300 and the second fan 400 can be limited by the fastener 520, the transmission section 511 can be more stably sleeved with the first fan 300 and the second fan 400, the first fan 300 and the second fan 400 are prevented from shifting, and the vibration and noise generated during rotation of the second fan 400 and the first fan 300 are further reduced.

[0290] Moreover, the support section 513 is provided and may be beyond a side of the fastener 520 facing away from the second fan 400. In this way, the support section 513 and the air duct member fixing portion 227 can be connected, and the air duct member fixing portion 227 can support the output shaft 510 by supporting the support section 513, thus avoiding position interference of the output shaft fixing portion 512, the fastener 520 and the air duct member fixing portion 227. The free end of the output shaft 510 can be more easily mounted in the air duct member fixing portion 227, and the connection between the output shaft 510 and the air duct member fixing portion 227 is more stable and reliable.

[0291] In some embodiments of the present disclosure, as shown in FIG. 54 and FIG. 56, the air duct member fixing portion 227 is provided with a shaft sleeve fixing structure 228, a shaft sleeve 560 is mounted in the shaft sleeve fixing structure 228, and the output shaft 510 is arranged through the shaft sleeve 560.

[0292] The shaft sleeve fixing structure 228 may be configured as a fixing hole.

[0293] For example, the shaft sleeve 560 may be fixed within the shaft sleeve fixing structure 228 of the air duct member fixing portion 227. Since the output shaft 510 is arranged through the shaft sleeve 560 and rotates relative to the shaft sleeve 560, on the one hand, the output shaft 510 can be supported by using the shaft sleeve 560, so as to cause the vibration of the output shaft 510 during rotation to be smaller; on the other hand, a resistance of the output shaft 510 during rotation can be reduced, and rotational friction between the shaft sleeve 560 and the output shaft 510 may be smaller, so that abrasion of the output shaft 510 may be reduced and rotation of the output shaft 510 may be easier.

[0294] Further, as shown in FIG. 56, the shaft sleeve fixing structure 228 includes an accommodating section 2281 and a stopping section 2282.

[0295] The stopping section 2282 is arranged on a side of the accommodating section 2281 facing away from the output shaft 510. An inner diameter of the accommodating section 2281 is larger than that of the stopping section 2282, and the shaft sleeve 560 is mounted in the accommodating section 2281 and stopped at the stopping section 2282.

[0296] That is, the shaft sleeve 560 is mounted in the accommodating section 2281, and the stopping section 2282 may limit the shaft sleeve 560 in an axial direction. In this way, the shaft sleeve 560 can be closer to a side of the shaft sleeve fixing structure 228 facing the output shaft 510, so as to facilitate the output shaft 510 to be arranged through the shaft sleeve 560.

[0297] In addition, the output shaft 510 may pass through the shaft sleeve 560 and extend into the stopping section 2282, and the stopping section 2282 may avoid position interference between the output shaft 510 and a hole wall of the shaft sleeve fixing structure 228, so as to facilitate the rotation of the output shaft 510. Alternatively, the output shaft 510 may be inserted into the shaft sleeve 560 but not extend out of the shaft sleeve 560. That is, the output shaft 510 does not extend into the stopping section 2282. The arrangement of the stopping section 2282 can reduce a weight of the air duct member fixing portion 227, and the air duct member fixing portion 227 can be more easily fixed on the first air duct member 210 or the second air duct member 220 and is not prone to shake, so that the free end of the output shaft 510 can be supported by the air duct member fixing portion 227 and the shaft sleeve 560.

[0298] In some embodiments of the present disclosure, as shown in FIG. 58, the shaft sleeve 560 is provided with a shaft hole 562 and a plurality of vibration reduction portions 565. The output shaft 510 is arranged through the shaft hole 562, and the plurality of vibration reduction portions 565 are arranged at intervals along a circumferential direction of the shaft hole 562. The vibration reduction portion 565 may be configured as a vibration reduction hole.

[0299] Lubricating oil can be applied in the shaft hole 562 to facilitate relative rotation of the output shaft 510 and the shaft sleeve 560, and by providing the plurality of vibration reduction portions 565, not only a weight of the shaft sleeve 560 can be reduced, but also vibration transmission of the output shaft 510 can be reduced. That is, an amount of the vibration of the output shaft 510 transmitted to the air duct member fixing portion 227 through the shaft sleeve 560 can be smaller, and the shaft sleeve 560 can buffer the vibration of the output shaft 510, thereby further reducing the vibration and noise of the cabinet air conditioner and improving the use effect of the air conditioner.

[0300] In some embodiments of the present disclosure, as shown in FIG. 58, the shaft sleeve 560 includes an inner sleeve 561 and an outer sleeve 563.

[0301] The inner sleeve 561 is provided with the shaft hole 562, the outer sleeve 563 is arranged outside the inner sleeve 561, and the outer sleeve 563 and the inner sleeve 561 are connected by a plurality of connecting ribs 564. The outer sleeve 563, the inner sleeve 561 and adjacent connecting ribs 564 constitute the vibration reduction portion 565.

[0302] The plurality of connecting ribs 564 may be arranged at intervals along the circumferential direction of the shaft sleeve 560. That is, the plurality of vibration reduction portions 565 may be arranged at intervals along the circumferential direction of the shaft sleeve 560.

[0303] With this arrangement, the plural connecting ribs 564 may be respectively connected to the inner sleeve 561 and the outer sleeve 563, so that the vibration reduction portion 565 can be constructed between the adjacent connecting ribs 564, the vibration transmission of the output shaft 510 can be weakened by the shaft sleeve 560, connection strength of the inner sleeve 561 and the outer sleeve 563 can be ensured to be higher, overall structure strength of the shaft sleeve 560 is higher, and the shaft sleeve 560 is not easy to deform and damage.

[0304] As shown in FIG. 52 to FIG. 58, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0305] The heat exchanger is arranged in an upper chamber, the first air duct member 210 is arranged in a lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor air enters a room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510.

[0306] One of the first air duct member 210 and the second air duct member 220 is provided with a shaft sleeve 560, and an end of the output shaft 510 away from the electric motor 500 is rotatably arranged through the shaft sleeve 560.

[0307] For example, the electric motor 500 may be arranged in the first air duct member 210, and the output shaft 510 of the electric motor 500 extends towards the second air duct member 220. In this case, the shaft sleeve 560 may be arranged on the second air duct member 220, and the end of the output shaft 510 away from the electric motor 500 may be arranged through the shaft sleeve 560 on the second air duct member 220; alternatively, the electric motor 500 may be arranged in the second air duct member 220, and the output shaft 510 of the electric motor 500 extends towards the first air duct member 210. In this case, the shaft sleeve 560 may be arranged on the first air duct member 210, and the end of the output shaft 510 away from the electric motor 500 may be arranged through the shaft sleeve 560 on the first air duct member 210.

[0308] Thus, the end of the output shaft 510 away from the electric motor 500 may be rotatably connected with the shaft sleeve 560, and the shaft sleeve 560 may be configured to support a free end of the output shaft 510 without affecting the rotation of the output shaft 510, so that the electric motor 500 may drive the second fan 400 and the first fan 300 to rotate through the output shaft 510. After the shaft sleeve 560 supports the free end of the output shaft 510, the rotation of the output shaft 510 can be more stable. That is, vibration of the output shaft 510 during rotation can be smaller, and the output shaft 510 is not prone to shake, so that the vibration of the output shaft 510 and noise generated by the vibration can be greatly reduced, vibration and noise during operation of the cabinet air conditioner are smaller, and a use effect of the air conditioner is improved.

[0309] In the cabinet air conditioner according to some embodiments of the present disclosure, support of the output shaft 510 of the electric motor 500 can be enhanced, the rotation of the output shaft 510 is more stable, and the vibration and rotation noise are smaller, thereby improving the use effect of the air conditioner.

[0310] In some embodiments of the present disclosure, as shown in FIG. 53 to FIG. 55, one of the first air duct member 210 and the second air duct member 220 protrudes towards the output shaft 510 to form an air duct member fixing portion 227. The shaft sleeve 560 is mounted on the air duct member fixing portion 227, and the end of the output shaft 510 away from the electric motor 500 is rotatably arranged through the shaft sleeve 560.

[0311] By causing the air duct member fixing portion 227 to protrude from the first air duct member 210 or the second air duct member 220, the shaft sleeve 560 can be conveniently fixed by the air duct member fixing portion 227, the air duct member fixing portion 227 may be closer to the end of the output shaft 510 away from the electric motor 500, and after the shaft sleeve 560 is mounted to the air duct member fixing portion 227, the shaft sleeve may be closer to the end of the output shaft 510 away from electric motor 500, so that the end of the output shaft 510 away from the electric motor 500 can be conveniently inserted into the air duct member fixing portion 227, and assembly is more convenient.

[0312] Other constructions and operations of the cabinet air conditioner according to some embodiments of the present disclosure are known to those of ordinary skill in the art and will not be described in detail herein.

[0313] The cabinet air conditioner according to the present disclosure performs a cooling cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to air that is conditioned and subjected to heat exchange.

[0314] The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to an ambient environment through the condensation process.

[0315] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat exchange between evaporation latent heat of the refrigerant and a material to be cooled. The cabinet air conditioner can adjust a temperature and humidity of an indoor space throughout the cycle.

[0316] It will be understood by those skilled in the art that the scope of the disclosure of the present disclosure is not limited to the particular embodiments described above, and that modifications and substitutions of certain elements of the embodiments may be made without departing from the spirit of the disclosure. The scope of the present disclosure is limited by the appended claims.

[0013] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to FIG. 1 to FIG. 10.

[0014] An air conditioner (hereinafter, with a cabinet air conditioner as an example) includes an indoor unit and an outdoor unit which are connected by a pipe to transport a refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan and an expansion valve. The compressor, the outdoor heat exchanger, the expansion valve and the indoor heat exchanger which are connected in sequence form a refrigerant loop, and the refrigerant circularly flows in the refrigerant loop, and exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger respectively, so as to realize a cooling mode or a heating mode of the cabinet air conditioner.

[0015] The compressor is configured to compress the refrigerant, so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0016] The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported in the outdoor heat exchanger. For example, the outdoor heat exchanger works as a condenser in the cooling mode of the cabinet air conditioner, so that the refrigerant compressed by the compressor radiates heat to the outdoor air by the outdoor heat exchanger to be condensed. The outdoor heat exchanger works as an evaporator in the heating mode of the cabinet air conditioner, so that the decompressed refrigerant absorbs heat of the outdoor air by the outdoor heat exchanger to be evaporated.

[0017] In some embodiments of the present disclosure, the outdoor heat exchanger further includes heat exchange fins to increase a contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving a heat exchange efficiency of the outdoor air and the refrigerant.

[0018] The outdoor fan is configured to suck the outdoor air into the outdoor unit through an outdoor air inlet of the outdoor unit, and deliver the outdoor air after heat exchange by the outdoor heat exchanger out through an outdoor air outlet of the outdoor unit. The outdoor fan supplies power to flowing of the outdoor air.

[0019] The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger, and a pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger is adjusted by an opening degree of the expansion valve, so as to adjust a flow rate of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger affect heat exchange performances of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve may be an electronic valve, and the opening degree of the expansion valve is adjustable to control a flow rate and pressure of the refrigerant flowing through the expansion valve.

[0020] The four-way valve is connected into the refrigerant loop, and the four-way valve is configured to switch a flow direction of the refrigerant in the refrigerant loop, so that the cabinet air conditioner implements the cooling mode or the heating mode.

[0021] The indoor heat exchanger is configured to exchange heat between indoor air and the refrigerant transported in the indoor heat exchanger. For example, the indoor heat exchanger works as an evaporator in the cooling mode of the cabinet air conditioner, so that the refrigerant dissipating heat through the outdoor heat exchanger absorbs heat of the indoor air by the indoor heat exchanger to be evaporated. The indoor heat exchanger works as a condenser in the heating mode of the cabinet air conditioner, so that the refrigerant absorbing heat through the outdoor heat exchanger dissipates heat to the indoor air by the indoor heat exchanger to be condensed.

[0022] In some embodiments of the present disclosure, the indoor heat exchanger further includes heat exchange fins to increase a contact area between the indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving a heat exchange efficiency of the indoor air and the refrigerant.

[0023] The indoor fan is configured to suck the indoor air into the indoor unit through a third air inlet 110 of the indoor unit and deliver the indoor air after heat exchange by the indoor heat exchanger out through a fourth air outlet 140 of the indoor unit. The indoor fan supplies power to flowing of the indoor air.

[0024] The cabinet air conditioner further includes a control device mainly configured to control a working frequency of the compressor, the opening degree of the expansion valve, a rotation speed of the outdoor fan and a rotation speed of the indoor fan. The control device is connected with the compressor, the expansion valve, the outdoor fan and the indoor fan through data cables to transmit communication information.

[0025] The control device includes a processor, and the processor may include a central processing unit (CPU), a microprocessor, and an application specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device.

[0026] As shown in FIG. 1 to FIG. 10, a cabinet air conditioner according to some embodiments of the present disclosure includes a ventilation assembly 200, and the ventilation assembly 200 can simultaneously suck fresh air into a room and discharge indoor air.

[0027] As shown in FIG. 1 to FIG. 10, the cabinet air conditioner may further include a cabinet 100 and a heat exchanger, the cabinet 100 having an upper chamber and a lower chamber. Both the upper chamber and the lower chamber can achieve accommodating and mounting functions, and other corresponding components in the cabinet air conditioner can be mounted in the upper chamber and the lower chamber.

[0028] For example, the heat exchanger may be arranged in the upper chamber, so that the heat exchanger may be separated from the lower chamber. The heat exchanger may achieve a heat exchange function in the upper chamber, so as to perform heat exchange on indoor air. The ventilation assembly 200 may be arranged in the lower chamber.

[0029] As shown in FIG. 1 to FIG. 5, the ventilation assembly 200 is configured to deliver outdoor air into a room and deliver the indoor air to the outside. That is, the ventilation assembly 200 can discharge the indoor dirty air to the outside while delivering the outdoor fresh air into the room, thereby better refreshing the indoor air.

[0030] The ventilation assembly 200 includes a first air duct member 210, the outdoor fresh air enters the room through the first air duct member 210, a first air inlet 211 and a first air outlet 212 are formed in the first air duct member 210, and a first air duct 201 is formed between the first air inlet 211 and the first air outlet 212. The ventilation assembly 200 further includes a second air duct member 220, the indoor air is exhausted from the room through the second air duct member 220, a second air inlet 221 and a second air outlet 222 are formed in the second air duct member 220, and a second air duct 202 is formed between the second air inlet 221 and the second air outlet 222.

[0031] The first air duct 210 is a fresh air duct, the first air inlet 211 is a fresh air inlet configured to introduce the outdoor fresh air into the first air duct member 210, and the first air outlet 212 is a fresh air outlet configured to discharge the outdoor fresh air out of the first air duct member 210 into the room. The second air duct 220 is an exhaust air duct, the second air inlet 221 is an indoor air inlet configured to introduce the indoor air into the second air duct member 220, and the second air outlet 222 is an indoor air outlet configured to discharge the indoor turbid air to the outside.

[0032] The first air duct member 210 is a structural member through which an air stream passes, and the first air duct member 210 is arranged in the lower chamber. Thus, the arrangement of the first air duct member 210 is more reasonable, interference with heat exchange of the upper chamber can be avoided, and the first air duct member 210 can better achieve an air stream passing function.

[0033] The first air inlet 211 mainly plays an air inlet role, the first air outlet 212 mainly plays an air outlet role, and the first air duct 201 can achieve the function of guiding air circulation. The outdoor fresh air enters the first air duct member 210 through the first air inlet 211, and then enters the room through the first air outlet 212 along the first air duct 201, so that the outdoor fresh air can be introduced.

[0034] Similarly, the second air duct member 220 is also a structural member through which an air stream passes, and the second air duct member 220 is arranged in the lower chamber, so that the arrangement of the second air duct member 220 is more reasonable, interference with heat exchange of the upper chamber can be avoided, and the second air duct member 220 can better achieve an air stream passing function.

[0035] The second air inlet 221 mainly plays an air inlet role, the second air outlet 222 mainly plays an air outlet role, and the second air duct 202 can achieve the function of guiding air circulation. The indoor dirty air enters the second air duct member 220 through the second air inlet 221, and then is discharged to the outside through the second air outlet 222 along the second air duct 202, so that the indoor dirty air can be discharged.

[0036] As shown in FIG. 3, the ventilation assembly 200 further includes a first fan 300, and the first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the outside. This arrangement is more reasonable, and when the first fan 300 works, the first fan 300 sucks the indoor dirty air into the second air duct 202, and then discharges the indoor dirty air to the outside from the second air duct 202, so that the indoor dirty air can be discharged. The first fan 300 may be an exhaust fan.

[0037] As shown in FIG. 3, the ventilation assembly 200 further includes a second fan 400, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. This arrangement is more reasonable, and when the second fan 400 works, the second fan 400 can suck the outdoor fresh air into the first air duct 201, and then release the outdoor fresh air into the room from the first air duct 201, so that the outdoor fresh air can be introduced. The second fan 400 may be a fresh air fan.

[0038] As shown in FIG. 3 and FIG. 6, the ventilation assembly 200 further includes an electric motor 500, the electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate.

[0039] The electric motor 500 mainly achieves a driving function, and the electric motor 500 has the single output shaft 510. That is, the electric motor 500 outputs power outwards through only one output shaft 510. The first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. When the electric motor 500 works, the electric motor 500 may simultaneously drive the first fan 300 and the second fan 400 to rotate through the output shaft 510. In this way, the second fan 400 can suck the outdoor fresh air while the first fan 300 discharges the indoor dirty air.

[0040] As shown in FIG. 3, FIG. 7 and FIG. 8, the electric motor 500 is arranged in one of the first fan 300 and the second fan 400, and one of the first fan 300 and the second fan 400 is provided with an accommodating portion 310 to accommodate the electric motor 500. The other of the first fan 300 and the second fan 400 is provided with a clearance portion 410 to clear the accommodating portion 310, and the accommodating portion 310 is provided corresponding to the clearance portion 410.

[0041] For example, as shown in FIG. 7 and FIG. 8, the first fan 300 is provided with the accommodating portion 310, the second fan 400 is provided with the clearance portion 410, and the electric motor 500 may be arranged in the accommodating portion 310 of the first fan 300. In this way, the electric motor 500 may be arranged inside the first fan 300. Moreover, the clearance portion 410 may clear the accommodating portion 310. That is, the accommodating portion 310 may be located within the clearance portion 410. In this way, a size of the clearance portion 410 and the accommodating portion 310 in a fitting direction may be reduced, thereby reducing a volume of the ventilation assembly 200.

[0042] In addition, the clearance portion 410 is arranged opposite to the accommodating portion 310, so that a size of the clearance portion 410 and the accommodating portion 310 in an opposite direction can be reduced, thereby reducing the volume of the ventilation assembly 200. The accommodating portion 310 may have a convex structure, and the clearance portion 410 may have a concave structure.

[0043] In addition, one of the first fan 300 and the second fan 400 is provided with a first rotation stopping portion 320, the other is provided with a second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at a same frequency.

[0044] It should be noted that the first rotation stopping portion 320 fits the second rotation stopping portion 420 to stop rotation of the second fan 400 and the first fan 300 in a circumferential direction of the output shaft 510. That is, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Meanwhile, the first rotation stopping portion 320 fits the second rotation stopping portion 420 to position assembly of the second fan 400 and the first fan 300.

[0045] Therefore, even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first rotation stopping portion 320 fits the second rotation stopping portion 420, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and in this case, the rotation speed of the second fan 400 is lower than that of the first fan 300. After the first rotation stopping portion 320 fits the second rotation stopping portion 420, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0046] Thus, by providing the accommodating portion 310 in one of the first fan 300 and the second fan 400, providing the clearance portion 410 in the other, and providing the electric motor 500 in the first fan 300 or the second fan 400, under the condition of simultaneously exhausting the air of the room and sucking the air into the room, the volume occupied by the ventilation assembly 200 can be reduced, a cost is reduced, and universality of the cabinet air conditioner is improved.

[0047] In addition, the accommodating portion 310 is formed to protrude from an end surface of one of the first fan 300 and the second fan 400 towards the other of the first fan 300 and the second fan 400 along an axis of the first fan 300. That is, a structure of the accommodating portion 310 is configured to be convex towards the clearance portion 410, and correspondingly, since the clearance portion 410 is provided corresponding to the accommodating portion 310, the clearance portion 410 is configured to be concave.

[0048] For example, the accommodating portion 310 is arranged on the first fan 300, the clearance portion 410 is arranged on the second fan 400, and the accommodating portion 310 protrudes towards the second fan 400 along the axis of the first fan 300. In this way, the accommodating portion 310 and the clearance portion 410 can be better matched to mount the electric motor 500 in the accommodating portion 310. Thus, an additional space occupied by the electric motor 500 may be reduced, thereby reducing the overall volume of the ventilation assembly 200.

[0049] In some embodiments of the present disclosure, as shown in FIG. 7, the accommodating portion 310 includes a first protrusion 311 and a second protrusion 312. The first protrusion 311 may be provided therein with a cavity, and the second protrusion 312 mainly achieves a connection function.

[0050] As shown in FIG. 3, FIG. 7 and FIG. 8, the first protrusion 311 protrudes towards the clearance portion 410, so that the first protrusion 311 can be better matched with the clearance portion 410, thereby reducing a volume of the first protrusion 311 and the clearance portion 410 after fitting. The electric motor 500 is at least partially arranged within the first protrusion 311. That is, the electric motor 500 is at least partially arranged within the cavity formed within the first protrusion 311. In this way, the electric motor 500 can conveniently fit the first fan 300 or the second fan 400, and the additional space occupied by the electric motor 500 can be reduced, thereby reducing the overall volume of the ventilation assembly 200.

[0051] As shown in FIG. 3 and FIG. 7, the second protrusion 312 protrudes towards the clearance portion 410, and the second protrusion 312 is connected to a side of the first protrusion 311 adjacent to the clearance portion 410. In this way, interference of the second protrusion 312 with the arrangement of the electric motor 500 can be avoided, and meanwhile, the size of the clearance portion 410 and the accommodating portion 310 in the opposite direction can be reduced. The electric motor 500 is in transmission connection with the second protrusion 312, so that the electric motor 500 can provide power for the second protrusion 312. That is, the electric motor 500 may drive the second protrusion 312 to rotate, so as to drive the first fan 300 or the second fan 400 to rotate, thereby exhausting the air or sucking the air.

[0052] In some embodiments of the present disclosure, as shown in FIG. 7, a sectional area of the first protrusion 311 gradually decreases towards the clearance portion 410. In this way, in the case of ensuring that the formed cavity is enough to fit the electric motor 500, a volume of the first protrusion 311 may be reduced, thereby reducing a manufacturing cost of the first protrusion 311. Moreover, the first protrusion 311 forms a structure with a slanted surface, which may improve structural strength of the accommodating portion 310 to some extent.

[0053] In some embodiments of the present disclosure, as shown in FIG. 3 and FIG. 8, the clearance portion 410 includes a plurality of connecting strips 411 and a connecting plate 412. The plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other, the connecting plate 412 is respectively connected with the plurality of connecting strips 411, and the electric motor 500 is also in transmission connection with the connecting plate 412.

[0054] The connecting strips 411 mainly achieve a connection function, and the plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other. That is, the plurality of connecting strips 411 have an inclined structure that converges towards a center, so that the inclined arrangement of the plurality of connecting strips 411 corresponds to the structure of the accommodating portion 310, and the accommodating portion 310 may be arranged opposite to the clearance portion 410. Moreover, the plurality of connecting strips 411 extend away from the accommodating portion 310 and approach each other. In this way, the accommodating portion 310 may be fitted between the plurality of connecting strips 411, so that the clearance portion 410 fits the accommodating portion 310, the size of the clearance portion 410 and the accommodating portion 310 in the opposite direction is reduced, and then, a volume of the first fan 300 and the second fan 400 after fitting may be reduced.

[0055] The connecting plate 412 mainly has a connection function, and the connecting plate 412 is connected with the plurality of connecting strips 411. Thus, the connecting plate 412 can be fixed, and the connecting plate 412 can be more firmly and stably arranged. Since the electric motor 500 is also in transmission connection with the connecting plate 412, the electric motor 500 can drive the connecting plate 412 to rotate while driving the second protrusion 312 to rotate. That is, the electric motor 500 may simultaneously drive the accommodating portion 310 and the clearance portion 410 to rotate, so as to simultaneously drive the first fan 300 and the second fan 400 to rotate, thereby simultaneously sucking the air into the room and exhausting the air of the room.

[0056] In some embodiments of the present disclosure, as shown in FIG. 1 to FIG. 5, the cabinet air conditioner further includes a first air duct shell 223, a second air duct shell 224 and a third air duct shell 213. The first air duct shell 223 constitutes a first part of the second air duct member 220, and the first air duct shell 223 constitutes a first part of the first air duct member 210. The second air duct shell 224 constitutes a second part of the second air duct member 220, and the third air duct shell 213 constitutes a second part of the first air duct member 210.

[0057] The first air duct shell 223, the second air duct shell 224, and the third air duct shell 213 are all structural members through which an air stream passes.

[0058] The first air duct shell 223 constitutes the first part of the second air duct member 220, and the second air duct shell 224 constitutes the second part of the second air duct member 220. That is, the first air duct shell 223 and the second air duct shell 224 may constitute the complete second air duct member 220, so that the indoor dirty air can be discharged inside the second air duct member 220. Certainly, the first fan 300 is arranged in the second air duct 202 in the second air duct member 220. Thus, the first fan 300 can suck the indoor dirty air into the second air duct member 220 through the second air inlet 221, and then discharge the indoor dirty air to the outside from the second air duct member 220 through the second air outlet 222, so as to exhaust the indoor air.

[0059] The first air duct shell 223 constitutes the first part of the first air duct member 210, and the third air duct shell 213 constitutes the second part of the first air duct member 210. That is, the first air duct shell 223 and the third air duct shell 213 may constitute the complete first air duct member 210. Thus, the outdoor fresh air can enter the first air duct member 210 through the first air inlet 211. Certainly, the second fan 400 is arranged in the fresh air duct of the first air duct member 210. Thus, the second fan 400 can suck the outdoor fresh air into the first air duct member 210 through the first air inlet 211, and then release the outdoor fresh air into the room from the first air duct member 210 through the first air outlet 212, so as to release the fresh air into the room.

The limiting portion 2231 is arranged on the first air duct shell 223, so that a fitting structure may be formed on the first air duct shell 223, and therefore, the first air duct shell 223 may better fit the second air duct shell 224 and the third air duct shell 213.

[0061] The limiting portion 2231 is located between the accommodating portion 310 and the clearance portion 410, and the limiting portion 2231 is provided to protrude towards the clearance portion 410. That is, protruding directions of the limiting portion 2231 and the accommodating portion 310 are the same. Thus, the accommodating portion 310 may better fit the limiting portion 2231, and meanwhile, the limiting portion 2231 may better fit the clearance portion 410, so that a volume of the first air duct shell 223, the second air duct shell 224, and the third air duct shell 213 after fitting may be reduced, and then, the overall volume of the ventilation assembly 200 may be reduced.

[0062] Further, as shown in FIG. 5 and FIG. 6, the cabinet air conditioner further includes a fastener 520. The electric motor 500 is provided with the output shaft 510, and an output shaft fixing portion 512 is arranged at an end portion of the output shaft 510.

[0063] The fastener 520 mainly achieves a fixing function, the output shaft 510 mainly achieves a torque transmission function, and the output shaft fixing portion 512 mainly achieves a fixing function. The output shaft 510 is arranged through the first fan 300 and the second fan 400, and the fastener 520 is fixed to the output shaft fixing portion 512. In this way, when the electric motor 500 simultaneously drives the first fan 300 and the second fan 400 to rotate, the first fan 300 and the second fan 400 can be limited in an axial direction of the output shaft 510 by the fastener 520, so that the first fan 300 and the second fan 400 can work more stably.

[0064] For example, as shown in FIG. 5 and FIG. 6, the fastener 520 is a nut, the output shaft fixing portion 512 is a threaded section having a surface provided with an external thread, and the nut fits the external thread. Thus, assembly between the fastener 520 and the output shaft fixing portion 512 can be simpler, a connection between the nut and the external thread is firm and stable, connection strength is high, and the nut and the external thread have simple structures and are convenient to process and provide.

[0065] In addition, as shown in FIG. 6, FIG. 9 and FIG. 10, the cabinet air conditioner further includes an electric motor bracket 530 and an electric motor pressing plate 540. The electric motor bracket 530 is fixed on the first air duct member 210 or the second air duct member 220, the electric motor pressing plate 540 is fixedly connected with the electric motor bracket 530, and the electric motor 500 is sandwiched between the electric motor bracket 530 and the electric motor pressing plate 540.

[0066] The electric motor bracket 530 mainly achieves a mounting function, the electric motor pressing plate 540 mainly achieves mounting and limiting functions, and by fixing the electric motor bracket 530 on the first air duct member 210 or the second air duct member 220, the electric motor bracket 530 can be fixed, and the electric motor bracket 530 is more firmly and stably arranged. The electric motor pressing plate 540 is fixedly connected with the electric motor bracket 530, so that the electric motor pressing plate 540 can be fixed, the electric motor 500 can be sandwiched between the electric motor bracket 530 and the electric motor pressing plate 540, and therefore, the electric motor 500 can be limited and fixed by the electric motor bracket 530 and the electric motor pressing plate 540, and the electric motor 500 can work more stably.

[0067] In addition, as shown in FIG. 9 and FIG. 10, the electric motor bracket 530 is provided with a first mounting portion 531, and the electric motor pressing plate 540 is provided with a second mounting portion 541.

[0068] Each of the first mounting portion 531 and the second mounting portion 541 can achieve a mounting function, and the first mounting portion 531 and the second mounting portion 541 are correspondingly mounted and connected. In this way, the electric motor bracket 530 and the electric motor pressing plate 540 may be connected together by the first mounting portion 531 and the second mounting portion 541, so that the connection of the electric motor bracket 530 and the electric motor pressing plate 540 may be more stable, and therefore, the electric motor 500 may work better.

[0069] Each of the first positioning portion 532 and the second positioning portion 542 can achieve a positioning function, and the first positioning portion 532 and the second positioning portion 542 are in positioning fit.

Therefore, an assembling speed and assembling precision of the electric motor bracket 530 and the electric motor pressing plate 540 can be improved, and an assembling effect of the electric motor bracket 530 and the electric motor pressing plate 540 is improved.

[0070] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to FIG. 11 to FIG. 21.

[0071] Referring to FIG. 11 to FIG. 21, a cabinet air conditioner according to some embodiments of the present disclosure includes: a cabinet 100, a heat exchange blower, a first air duct member 210, a second air duct member 220, an electric motor 500, a first air duct 201, a second air duct 202, a purification air duct, a communication port 230, a first baffle 240 and a second baffle 250. The first air duct member 210 may be a fresh air duct member, the second air duct member 220 may be an exhaust air duct member, and the electric motor 500 may be a single-shaft electric motor.

[0072] An upper chamber and a lower chamber located below the upper chamber are formed inside the cabinet 100, and a third air inlet 110 and a third air outlet 120 are formed in the lower chamber. The second air duct 202 is defined from the third air inlet 110 to the third air outlet 120 in the cabinet air conditioner. The third air inlet 110 is an indoor air inlet, the third air outlet 120 is an indoor air outlet, a position of the third air inlet 110 corresponds to that of a second air inlet 221, so as to introduce indoor air into the cabinet through the third air inlet 110 and into the second air duct member 220 through the second air inlet 221, and a position of the third air outlet 120 corresponds to that of a second air outlet 222, so as to discharge indoor turbid air to the outside through the second air outlet 222 and the third air outlet 120 in sequence.

[0073] A fifth air inlet 160 and a fifth air outlet 170 are formed in the lower chamber, the first air duct 201 is defined between the fifth air inlet 160 and the fifth air outlet 170 in the cabinet air conditioner, the fifth air inlet 160 is a fresh air inlet, the fifth air outlet 170 is a fresh air outlet, a position of the fifth air inlet 160 corresponds to that of a first air inlet 211, so as to introduce outdoor fresh air into the cabinet through the fifth air inlet 160 and into the first air duct member 210 through the first air inlet 211, and a position of the fifth air outlet 170 corresponds to that of a first air outlet 212, so as to discharge the outdoor fresh air to the outside through the first air outlet 212 and the fifth air outlet 170 in sequence.

[0074] A fourth air inlet 130 and a fourth air outlet 140 are further formed in the lower chamber, and the purification air duct is defined from the fourth air inlet 130 to the fourth air outlet 140 in the cabinet air conditioner. The fourth air inlet 130 is a purified air inlet, the fourth air outlet 140 is a purified air outlet, and a position of the fourth air inlet 130 corresponds to that of the second air inlet 221, so that the indoor air is introduced into the cabinet through the fourth air inlet 130 and into the second air duct member 220 through the second air inlet 221, and the purified indoor air is discharged into a room through the fourth air outlet 140.

[0075] For example, the interior of the cabinet air conditioner is divided into an upper part and a lower part, the upper part is provided with the upper chamber, the lower part is provided with the lower chamber, and the upper chamber and the lower chamber are communicated through an air supply duct 150. The indoor air can enter the cabinet air conditioner from the third air inlet 110 formed in the lower chamber, and is exhausted to the outside from the third air outlet 120 after passing through the second air duct 202, and the outdoor fresh air can enter the cabinet air conditioner from the fifth air inlet 160 formed in the lower chamber, and is blown into the room from the fifth air outlet 170 after passing through the first air duct 201, so that the indoor air and the outdoor air can circulate to avoid that accumulation of harmful substances such as pollutants, bacteria and viruses in the indoor air lowers indoor air quality, which is not conducive to physical health of a user.

[0076] The lower chamber is further provided with the fourth air inlet 130 and the fourth air outlet 140, and when the user starts an indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet 130, and is discharged into the room from the fourth air outlet 140 after passing through the purification air duct, so that the indoor air can be filtered and purified, and the indoor air quality is improved. It should be noted that when the air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and in this case, the second air duct 202 is in an idle state.

[0077] In addition, the heat exchange blower is arranged in the upper chamber, and when the cabinet air conditioner operates, the heat exchange blower drives the indoor air to enter the cabinet 100, the indoor air forms a heat exchange air stream after exchanging heat with a heat exchanger, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room, so as to adjust an indoor temperature.

[0078] Referring to FIG. 11 to FIG. 13, the cabinet air conditioner further includes the first air duct member 210, the first air duct member 210 is arranged in the lower chamber, and the first air duct member 210 is configured to draw the outdoor air from the outside through the first air duct 201 and blow the air into the room. A fresh air cavity 214 is formed in the first air duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0079] That is, the first air duct member 210 is arranged in the lower chamber, the fresh air cavity 214 is formed inside the first air duct member 210, and the second fan 400 is arranged in the fresh air cavity 214. When the second fan 400 operates, the outdoor fresh air can be introduced from the fifth air inlet 160, discharged through the fifth air outlet 170 in the first air duct member 210, and driven by the heat exchange blower to enter the upper chamber from the air supply duct 150, and form a heat exchange air stream after exchanging heat with the heat exchanger in the upper chamber, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room. The fresh air is introduced and blown into the room through the first air duct member 210, so that the indoor air quality can be improved, more natural experience is provided for the user, and a use effect of the air conditioner is improved.

[0080] The cabinet air conditioner further includes the second air duct member 220, and the second air duct member 220 is arranged in the lower chamber and spaced apart from the first air duct member 210. The second air duct member 220 is configured to draw the indoor air from the room and discharge the air to the outside through the second air duct 202. An exhaust cavity 225 is formed in the second air duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0081] That is, the second air duct member 220 is arranged in the lower chamber, and the second air duct member 220 is spaced apart from the first air duct member 210 and located on a side of the first air duct member 210 away from the third air outlet 120. The exhaust cavity 225 is formed inside the second air duct member 220, and the first fan 300 is arranged in the exhaust cavity 225. When the first fan 300 operates, the indoor air can be introduced from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. Therefore, the dirty air accumulated in the room can be discharged to the outside, and the indoor air quality is improved.

[0082] In addition, the cabinet air conditioner further includes the electric motor 500, the electric motor 500 having a single output shaft 510, and the first fan 300 and the second fan 400 being connected to the output shaft 510. When the electric motor 500 operates, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 and the first air duct member 210 can fit each other to simultaneously suck the outdoor fresh air and discharge the indoor dirty air, so that good circulation of the indoor air is maintained, and the indoor air quality is improved.

[0083] The communication port 230 is configured to communicate the first air duct 201 and the exhaust air duct (second air duct 202). Since when the indoor air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, the second air duct 202 is in the idle state. Thus, under the condition that the communication port 230 is not blocked, when the outdoor air enters the first air duct 201 from the fifth air inlet 160, the outdoor air can also flow in the second air duct 202, and compared with a cabinet air conditioner in the related art, the cabinet air conditioner according to some embodiments of the present disclosure makes full use of existing components, and can effectively prevent the second air duct 202 from being idle without excessive modification, and moreover, a channel for introducing the fresh air into the cabinet air conditioner is changed from the original first air duct 201 to the first air duct 201 and the second air duct 202, so that an amount of the introduced fresh air can be increased, and the indoor air quality can be improved.

[0084] The cabinet air conditioner further includes the first baffle 240 and the second baffle 250, and the first baffle 240 is rotatably arranged in the second air duct 202 or the first air duct 201 to open or close the communication port 230. The second baffle 250 is rotatably arranged in the second air duct 202 or the purification air duct to communicate the third air inlet 110 and the third air outlet 120 and disconnect the third air inlet 110 from the fourth air outlet 140.

[0085] That is, the first baffle 240 may rotate within the second air duct 202 or the first air duct 201, and a rotation angle may be a clockwise angle or a counterclockwise angle. The first baffle 240 may be configured to open or close the communication port 230, so as to control communication between the first air duct 201 and the second air duct 202.

[0086] The second baffle 250 may rotate within the second air duct 202 or the purification air duct, and a rotation angle may be a clockwise angle or a counterclockwise angle. The second baffle 250 may be located at the purification air duct to block air flow between the third air inlet 110 and the fourth air outlet 140 and communicate the third air inlet 110 and the third air outlet 120. In this case, an exhaust mode runs normally. The second baffle 250 may be located at the second air duct 202, so as to block air flow between the third air inlet 110 and the third air outlet 120 and communicate the third air inlet 110 and the fourth air outlet 140, and in this case, the indoor air circulation purification mode is started.

[0087] Thus, by arranging the communication port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the communication port 230 fit each other to control communication and a disconnection of the first air duct 201 and the second air duct 202, the second baffle 250 can control switching between the exhaust mode and the indoor air circulation purification mode, and when the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are communicated through the communication port 230, and the second air duct 202 is changed into the first air duct 201, so that the amount of the fresh air of the cabinet air conditioner is increased, and the air quality of a human living environment is improved.

[0088] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, the first baffle 240 has a first position and a second position. When the first baffle 240 is located at the first position, the first baffle 240 blocks the communication port 230; when the first baffle 240 is located at the second position, the first baffle 240 opens the communication port 230, so that the first air duct member 210 draws the outdoor air from the outside through the first air duct 201 and the second air duct 202.

[0089] For example, when the first baffle 240 is at the first position, the first baffle 240 may block the communication port 230. In this case, air cannot circulate in the first air duct 201 and the second air duct 202, and the second air duct 202 and the first air duct 201 function to discharge the indoor dirty air and suck the outdoor fresh air respectively.

[0090] For another example, after the first baffle 240 is rotated clockwise by an angle, the first baffle 240 is located at the second position. In this case, the first baffle 240 does not block the communication port 230, the air can circulate in the first air duct 201 and the second air duct 202, the second air duct 202 can be used as the first air duct 201, and the fresh air is introduced by the first air duct 201 and the second air duct 202 simultaneously, so that the amount of the fresh air is increased, more fresh air is introduced into the room, and the indoor air quality is improved.

[0091] When the cabinet air conditioner is not in the indoor air circulation purification mode, the first baffle 240 may be rotated counterclockwise by an angle to return to the first position to block the communication port 230, so that the second air duct 202 and the first air duct 201 function to discharge the indoor dirty air and suck the outdoor fresh air respectively.

[0092] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, when the first baffle 240 is located at the first position, an orthographic projection of the first baffle 240 on a horizontal plane covers an orthographic projection of the communication port 230 on the horizontal plane. That is, an area of the first baffle 240 is larger than an area of the communication port 230, and the orthographic projection of the first baffle 240 on the horizontal plane can cover the orthographic projection of the communication port 230 on the horizontal plane. Thus, the first baffle 240 can effectively block the communication port 230 when located at the first position, thus avoiding the overflow of the air from the communication port 230 into the second air duct 202 or the first air duct 201 when the second air duct 202 discharges the indoor air or the first air duct 201 sucks the outdoor air, which would otherwise mix the indoor air and hinder the improvement of the indoor air quality. The horizontal plane may be a plane of the first baffle 240 at the communication port 230.

[0093] In some embodiments of the present disclosure, referring to FIG. 12 and FIG. 13, the second baffle 250 has a third position and a fourth position. When the second baffle 250 is located at the third position, the second baffle 250 disconnects the third air inlet 110 from the third air outlet 120 and communicates the third air inlet 110 and the fourth air inlet 130. When the second baffle 250 is located at the fourth position, the second baffle 250 disconnects the third air inlet 110 from the fourth air outlet 140 and communicates the third air inlet 110 and the third air outlet 120.

[0094] For example, when the second baffle 250 is located at the third position, the second baffle 250 may disconnect the third air inlet 110 from the third air outlet 120, and due to the blocking of the second baffle 250, the indoor air drawn by the second air duct member 220 cannot be discharged to the outside through the second air duct 202, and can only be delivered into the room, and in this case, the cabinet air conditioner is in the indoor air circulation purification mode, and the second air duct 202 is in the idle state. In this case, the first baffle 240 may be located at the second position, the communication port 230 communicates the first air duct 201 with the second air duct 202, and the first air duct member 210 may introduce the outdoor fresh air from the first air duct 201 and the second air duct 202 at the same time, so that an amount of the indoor fresh air is increased, and the air quality of the indoor human living environment is greatly improved.

[0095] For another example, when the second baffle 250 is located at the fourth position, the second baffle 250 is rotated counterclockwise by an angle from the third position. Thus, the third air inlet 110 and the third air outlet 120 are communicated. In this case, the first baffle 240 may be at the first position to block the communication port 230, the second air duct 202 may be separated from the first air duct 201, the air drawn from the room by the second air duct member 220 may sequentially pass through the third air outlet 120 and the second air duct 202 to be discharged to the outside, and the dirty air accumulated in the room may be discharged, so that circulation of the indoor air may be maintained, and the indoor air quality may be improved.

[0096] In some embodiments of the present disclosure, referring to FIG. 14 and FIG. 15, the second baffle 250 and the first baffle 240 are of an integrally formed structure. A pivot portion 241 of the first baffle 240 and the second baffle 250 is arranged at an interface between the second baffle 250 and the first baffle 240, so that the first baffle 240 and the second baffle 250 rotate about the pivot portion 241. The cabinet air conditioner further includes a first driving member which is in transmission fit with the pivot portion 241. For example, the pivot portion 241 is arranged between the first baffle 240 and the second baffle 250, the cabinet air conditioner is provided with the first driving member, and the first driving member is in transmission fit with the pivot portion 241. That is, the first driving member may drive the first baffle 240 and the second baffle 250 to rotate about the pivot portion 241, and the first driving member may be the electric motor 500. The first baffle 240 and the second baffle 250 are of the integrally formed structure, and rotation ranges of the first baffle 240 and the second baffle 250 are both angles.

[0097] Thus, the second baffle 250 is at the fourth position when the first baffle 240 is at the first position. In this case, the first baffle 240 blocks the communication port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 and the third air outlet 120 are communicated with each other. In this case, the second air duct 202 is only configured to fit the second air duct member 220 to discharge the indoor air, thus maintaining the circulation of the indoor air.

[0098] When the first baffle 240 is at the second position, the second baffle 250 is at the third position. In this case, the communication port 230 between the second air duct 202 and the first air duct 201 is opened, the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250, and the indoor air drawn by the second air duct member 220 cannot be discharged through the second air duct 202, is then output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, so that the indoor air circulation purification mode is formed. Under driving of the first air duct member 210, the second air duct 202 and the first air duct 201 are communicated to jointly draw the fresh air from the outside, so that the second air duct 202 is used to introduce the fresh air while the indoor air circulation purification mode is realized, the second air duct 202 is prevented from being idle, the amount of the fresh air can be increased, the indoor air is kept fresh, and the air quality of the indoor human living environment is improved greatly.

[0099] In some embodiments of the present disclosure, referring to FIG. 15, a clearance space 251 is formed between the first baffle 240 and the second baffle 250. When the second baffle 250 is located at the third position and the first baffle 240 is located at the second position, an orthographic projection of the clearance space 251 on the horizontal plane covers the orthographic projection of the communication port 230 on the horizontal plane, so that the clearance space 251 is communicated with the communication port 230. Since the first baffle 240 and the second baffle 250 are of the integrally formed structure, in order to achieve the aim that the communication port 230 is not blocked when the first baffle 240 rotates to the second position and the second baffle 250 rotates to the third position, the clearance space 251 is formed between the first baffle 240 and the second baffle 250, and when the second baffle 250 is located at the third position, the orthographic projection of the clearance space 251 on the horizontal plane covers the orthographic projection of the communication port 230 on the horizontal plane.

[0100] That is, an area of the clearance space 251 is larger than the area of the communication port 230, and when the first baffle 240 and the second baffle 250 rotate around the pivot portion 241 to the second position and the third position, the first baffle 240 and the second baffle 250 do not block the communication port 230, so that smooth air circulation between the second air duct 202 and the first air duct 201 can be ensured, and a large amount of fresh air can be introduced.

[0101] The cabinet air conditioner further includes a second driving member and a third driving member. The second driving member is in transmission connection with the first baffle 240, so as to drive the first baffle 240 to rotate between the first position and the second position. The third driving member is in transmission connection with the second baffle 250, so as to drive the second baffle 250 to rotate between the third position and the fourth position. That is, the first baffle 240 and the second baffle 250 may be driven by different driving members, the cabinet air conditioner further includes the second driving member and the third driving member, the second driving member is in transmission connection with the first baffle 240, the third driving member is in transmission connection with the second baffle 250, and the second driving member and the third driving member respectively drive the first baffle 240 and the second baffle 250 to rotate.

[0102] Thus, the second baffle 250 may be at the third position when the first baffle 240 is at the first position. In this case, the communication port 230 is blocked by the first baffle 240, the third air inlet 110 and the third air outlet 120 are also separated by the second baffle 250, the air drawn from the room by the second air duct member 220 can only be output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, the second air duct member 220 only performs the indoor air circulation purification mode, and the second air duct 202 is in the idle state. The second baffle 250 may also be at the fourth position when the first baffle 240 is at the first position. In this case, the first baffle 240 blocks the communication port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 and the third air outlet 120 are communicated with each other. In this case, the second air duct 202 is only configured to fit the second air duct member 220 to discharge the indoor air, thus maintaining the circulation of the indoor air.

[0103] When the first baffle 240 is at the second position, the second baffle 250 may be at the third position. In this case, the communication port 230 between the second air duct 202 and the first air duct 201 is opened, the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250, and the indoor air drawn by the second air duct member 220 cannot be discharged through the second air duct 202, is then output into the upper chamber, and is output into the room after heat exchange by the heat exchanger, so that the indoor air circulation purification mode is formed. Under driving of the first air duct member 210, the second air duct 202 and the first air duct 201 are communicated to jointly draw the fresh air from the outside, so that the second air duct 202 is used to introduce the fresh air while the indoor air circulation purification mode is realized, the second air duct 202 is prevented from being idle, the amount of the fresh air can be increased, the indoor air is kept fresh, and the air quality of the indoor human living environment is improved greatly.

[0104] However, when the first baffle 240 is located at the second position, the second baffle 250 cannot be located at the fourth position, otherwise, when the second air duct 202 is communicated with the first air duct 201, the third air inlet 110 is also communicated with the third air outlet 120, so that the indoor dirty air and the outdoor fresh air are mixed to reduce the indoor fresh air and reduce the air quality.

[0105] In some embodiments of the present disclosure, referring to FIG. 14, the second air duct member 220 is provided with the second air inlet 221, and the second air inlet 221 and the third air inlet 110 are oppositely arranged. The cabinet air conditioner further includes an exhaust filter portion 226, and the exhaust filter portion 226 is fixed to an inner side of the cabinet 100 and sandwiched between the third air inlet 110 and the second air inlet 221. The indoor air is driven by the second air duct member 220 to enter the second air duct 202 through the second air inlet 221 and the third air inlet 110, and since the exhaust filter portion 226 is sandwiched between the third air inlet 110 and the second air inlet 221, the indoor air sucked by the second air duct member 220 can be filtered, and the air filtered by the exhaust filter portion 226 enters the room from the purification air duct to participate in indoor air circulation, so that the indoor air can be purified, and the air quality is improved. The exhaust filter portion 226 may be a filter screen.

[0106] In some embodiments of the present disclosure, referring to FIG. 14, the cabinet air conditioner further includes a fresh air filter portion 215, and the fresh air filter portion 215 is arranged in the first air duct 201 and opposite to the fifth air inlet 160. Since the second fan 400 operates to suck the outdoor fresh air into the first air duct 201 through the fifth air inlet 160, and the fresh air filter portion 215 is arranged in the first air duct 201 and opposite to the fifth air inlet 160, the air sucked from the outside is filtered by the fresh air filter portion 215, so that cleanliness of the air blown out by the air conditioner can be improved, and an improvement of the human living environment is facilitated. The fresh air filter portion 215 may be a filter screen.

[0107] As shown in FIG. 14 and FIG. 16, the cabinet air conditioner further includes an opening-closing member 161, the opening-closing member 161 is rotatably arranged at the fifth air inlet 160, and the opening-closing member 161 has a fifth position and a sixth position. When the opening-closing member 161 is located at the fifth position, the opening-closing member 161 closes the fifth air inlet 160, and when the opening-closing member 161 is located at the sixth position, the opening-closing member 161 opens the fifth air inlet 160.

[0108] For example, the opening-closing member 161 is located at the fifth air inlet 160 and configured to control opening and closing of the first air duct 201. When the first air duct member 210 stops operating and the opening-closing member 161 is located at the fifth position, the opening-closing member 161 closes the fifth air inlet 160, so that noise generated when outdoor air flows backwards into the first air duct member 210 can be effectively avoided, and a good silencing effect is provided for an indoor space. When the opening-closing member 161 is located at the sixth position, the opening-closing member 161 opens the fifth air inlet 160, and the outdoor fresh air can enter the cabinet 100 from the fifth air inlet 160 to provide fresh air for the room. The opening-closing member 161 may be controlled by the electric motor 500.

[0109] Referring to FIG. 11 to FIG. 21, a cabinet air conditioner according to some embodiments of the present disclosure includes: a cabinet 100, a heat exchange blower, a first air duct member 210, a second air duct member 220, an electric motor 500, a first air duct 201, a second air duct 202, a purification air duct, a communication port 230, a first baffle 240 and a second baffle 250.

[0110] An upper chamber and a lower chamber located below the upper chamber are formed inside the cabinet 100, and a third air inlet 110 and a third air outlet 120 are formed in the lower chamber. The lower chamber is provided with a fifth air inlet 160 and a fifth air outlet 170. The lower chamber is further provided with a fourth air inlet 130 and a fourth air outlet 140, and the heat exchange blower is arranged in the upper chamber. In addition, in the cabinet air conditioner, the first air duct 201 is defined from the fifth air inlet 160 to the fifth air outlet 170, the second air duct 202 is defined from the third air inlet 110 to the third air outlet 120, and the purification air duct is defined from the fourth air inlet 130 to the fourth air outlet 140.

[0111] For example, the interior of the cabinet air conditioner is divided into an upper part and a lower part, the upper part is provided with the upper chamber, the lower part is provided with the lower chamber, and the upper chamber and the lower chamber are communicated through an air supply duct 150. Indoor air can enter the cabinet air conditioner from the third air inlet 110 formed in the lower chamber, and is exhausted to the outside from the third air outlet 120 after passing through the second air duct 202. Outdoor fresh air can enter the cabinet air conditioner from the fifth air inlet 160 formed in the lower chamber, and is blown into a room from the fifth air outlet 170 after passing through the first air duct 201. Therefore, the indoor air and the outdoor air can circulate, and it is avoided that accumulation of harmful substances such as pollutants, bacteria and viruses in the indoor air reduces indoor air quality.

[0112] The fourth air inlet and the fourth air outlet are also formed in the lower chamber. When a user starts an indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet, and is discharged into the room from the fourth air outlet after passing through the purification air duct, so that the indoor air can be filtered and purified, and the indoor air quality is improved. It should be noted that when the air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and in this case, the second air duct 202 is in an idle state.

[0113] In addition, the heat exchange blower is arranged in the upper chamber. When the cabinet air conditioner operates, the heat exchange blower drives the indoor air to enter the cabinet 100, the indoor air forms a heat exchange air stream after exchanging heat with a heat exchanger, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room, so as to adjust an indoor temperature.

[0114] Referring to FIG. 12 and FIG. 13, the cabinet air conditioner further includes the first air duct member 210, the first air duct member 210 is arranged in the lower chamber, and the first air duct member 210 is configured to draw the outdoor air from the outside through the first air duct 201 and blow the air into the room. A fresh air cavity 214 is formed in the first air duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0115] That is, the first air duct member 210 is arranged in the lower chamber, the fresh air cavity 214 is formed inside the first air duct member 210, and the second fan 400 is arranged in the fresh air cavity 214. When the second fan 400 operates, the outdoor fresh air can be introduced from the fifth air inlet 160, discharged through the fifth air outlet 170 in the first air duct member 210, and driven by the heat exchange blower to enter the upper chamber from the air supply duct 150, and form a heat exchange air stream after exchanging heat with the heat exchanger in the upper chamber, and the heat exchange air stream is driven by the heat exchange blower to be blown into the room. The fresh air is introduced and blown into the room through the first air duct member 210, so that the indoor air quality can be improved, more natural experience is provided for the user, and a use effect of the air conditioner is improved.

[0116] The cabinet air conditioner further includes the second air duct member 220, and the second air duct member 220 is arranged in the lower chamber and spaced apart from the first air duct member 210. The second air duct member 220 is configured to draw the indoor air from the room and discharge the air to the outside through the second air duct 202. An exhaust cavity 225 is formed in the second air duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0117] That is, the second air duct member 220 is arranged in the lower chamber, and the second air duct member 220 is spaced apart from the first air duct member 210 and located on a side of the first air duct member 210 away from the third air outlet 120. The exhaust cavity 225 is formed inside the second air duct member 220, and the first fan 300 is arranged in the exhaust cavity 225. When the first fan 300 operates, the indoor air can be introduced from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. Therefore, the dirty air accumulated in the room can be discharged to the outside, and the indoor air quality is improved.

[0118] In addition, the cabinet air conditioner further includes the electric motor 500, the electric motor 500 having a single output shaft 510, and the first fan 300 and the second fan 400 being connected to the output shaft 510. When the electric motor 500 operates, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 and the first air duct member 210 can fit each other to simultaneously suck the outdoor fresh air and discharge the indoor dirty air, so that good circulation of the indoor air is maintained, and the indoor air quality is improved.

[0119] The communication port 230 is configured to communicate the first air duct 201 and the exhaust air duct (second air duct 202). Since when the indoor air circulation purification mode is turned on, all the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, the second air duct 202 is in the idle state. In this way, when the communication port 230 is not blocked, the outdoor air may flow in the second air duct 202 when entering the first air duct 201 from the fifth air inlet 160. Compared with a cabinet air conditioner in the related art, the cabinet air conditioner according to some embodiments of the present disclosure makes full use of existing components, and can effectively prevent the second air duct 202 from being idle without excessive modification. Moreover, a channel for introducing the fresh air into the cabinet air conditioner is changed from the original first air duct 201 to the first air duct 201 and the second air duct 202, so that an amount of the introduced fresh air can be increased, and the indoor air quality can be improved.

[0120] The cabinet air conditioner further includes the first baffle 240 and the second baffle 250, and the first baffle 240 is rotatably arranged at the communication port 230 to open or close the communication port 230. The second baffle 250 is rotatably arranged in the second air duct 202 or the purification air duct to communicate the third air inlet 110 and the third air outlet 120 and disconnect the third air inlet 110 from the fourth air outlet.

[0121] That is, the first baffle 240 may rotate at the communication port 230, and a rotation angle may be a clockwise angle or a counterclockwise angle. The first baffle 240 may be configured to open or close the communication port 230, so as to control communication between the first air duct 201 and the second air duct 202.

[0122] The second baffle 250 may rotate within the second air duct 202 or the purification air duct, and a rotation angle may be a clockwise angle or a counterclockwise angle. The second baffle 250 may be located at the purification air duct to block air flow between the third air inlet 110 and the fourth air outlet and communicate the third air inlet 110 and the third air outlet 120. In this case, an exhaust mode runs normally. The second baffle 250 may be located at the second air duct 202, so as to block air flow between the third air inlet 110 and the third air outlet 120 and communicate the third air inlet 110 and the fourth air outlet, and in this case, the indoor air circulation purification mode is started.

[0123] Thus, by arranging the communication port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the communication port 230 fit each other to control communication and a disconnection of the first air duct 201 and the second air duct 202. The second baffle 250 can control switching between the exhaust mode and the indoor air circulation purification mode, and when the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are communicated through the communication port 230, and the second air duct 202 is changed into the first air duct 201, so that the amount of the fresh air of the cabinet air conditioner is increased, and the air quality of a human living environment is improved.

[0124] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0125] As shown in FIG. 22 to FIG. 29, a cabinet air conditioner according to some embodiments of the present disclosure includes a cabinet 100, a heat exchanger, a heat exchange blower, and a ventilation assembly 200.

[0126] As shown in FIG. 22, the cabinet 100 has an upper chamber and a lower chamber.

The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. The exhaust filter portion 226 is arranged on an air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0129] As shown in FIG. 24 to FIG. 29, the mounting bracket 600 includes a bracket body 610, an electric motor mounting portion 620, and a filter mounting portion 630. The bracket body 610 is connected with the second air duct member 220, the electric motor mounting portion 620 is connected to the bracket body 610, and the electric motor mounting portion 620 extends into the second air duct member 220. The electric motor 500 is mounted to the electric motor mounting portion 620. The filter mounting portion 630 is connected to the bracket body 610, and the exhaust filter portion 226 is mounted to the filter mounting portion 630.

[0130] The exhaust filter portion 226 may be a filter screen. The electric motor 500 has the single output shaft 510, which means that the electric motor 500 has only one output shaft 510, the output shaft 510 extends from one side of the electric motor 500, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510.

[0131] In the cabinet air conditioner according to some embodiments of the present disclosure, the cabinet 100 is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, and the heat exchange blower is configured to deliver the air subjected to heat exchange with the heat exchanger into the room. The ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0132] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0133] Moreover, the electric motor 500 has the single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. Thus, the first fan 300 and the second fan 400 can share one electric motor 500, which is beneficial to reducing a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated. Moreover, the exhaust filter portion 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter portion 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving quality of the air entering the cabinet air conditioner, and can improve quality of outlet air of the air conditioner and prevent dust and impurities from entering the cabinet 100.

[0134] In addition, the mounting bracket 600 includes the bracket body 610, the electric motor mounting portion 620, and the filter mounting portion 630. The electric motor 500 is mounted to the electric motor mounting portion 620, the filter mounting portion 630 is connected to the bracket body 610, and the exhaust filter portion 226 is mounted to the filter mounting portion 630.

[0135] That is, the mounting bracket 600 in some embodiments of the present disclosure may be configured to mount both the electric motor 500 and the exhaust filter portion 226. That is, the electric motor 500 and the exhaust filter portion 226 may be mounted on one bracket. Thus, a number of the brackets can be reduced, an integration level of the mounting bracket 600 is higher, assembly is more convenient and faster, and an improvement of an assembly efficiency is facilitated.

[0136] Moreover, it can be understood that, compared to the related art in which two brackets are provided to fix the electric motor 500 and the exhaust filter portion 226 respectively, in the cabinet air conditioner according to some embodiments of the present disclosure, one bracket may be omitted, thereby saving a set of molds for producing the bracket and facilitating a reduction of a production cost of the mounting bracket 600.

[0137] In addition, the bracket body 610 is connected with the second air duct member 220, the electric motor mounting portion 620 is connected to the bracket body 610, and the electric motor mounting portion 620 extends into the second air duct member 220, so that the filter mounting portion 630 may be located outside the second air duct member 220. Therefore, the electric motor 500 can extend into the second air duct member 220 after being mounted to the electric motor mounting portion 620, and the electric motor 500 can be close to the first fan 300 and the second fan 400, so as to facilitate the output shaft 510 of the electric motor 500 to be in transmission connection with the first fan 300 and the second fan 400 respectively. In addition, the exhaust filter portion 226 may be located outside the second air duct member 220 after being mounted to the filter mounting portion 630, so that the indoor air entering the second air duct member 220 can be filtered before entering the second air duct member 220, and the dust and the impurities are more effectively prevented from entering the second air duct member 220, so as to keep the interior of the second air duct member 220 clean, thereby improving the quality of the outlet air of the cabinet air conditioner.

[0138] In this way, in the cabinet air conditioner according to some embodiments of the present disclosure, the electric motor 500 and the exhaust filter portion 226 can be simultaneously fixed by the mounting bracket 600, and the cabinet air conditioner has the advantages of a high integration level, convenient assembly, cost saving, or the like.

[0139] In some embodiments of the present disclosure, as shown in FIG. 25, FIG. 27, and FIG. 28, the filter mounting portion 630 includes a frame 631 and a latch 632.

[0140] The frame 631 is connected to a side of the bracket body 610 facing away from the electric motor mounting portion 620, and the frame 631 and the bracket body 610 together form an accommodating space for accommodating the exhaust filter portion 226. The latch 632 is connected to the frame 631, and the latch 632 is located on a side of the exhaust filter portion 226 facing away from the bracket body 610 and configured to stop the exhaust filter portion 226.

[0141] For example, the frame 631 may have a circular shape, a rectangular shape, a polygonal shape, or another shape, and the shape may be configured according to a shape of the exhaust filter portion 226, so as to enable the frame 631 to surround the exhaust filter portion 226.

[0142] The exhaust filter portion 226 may be parallel to the bracket body 610, and the bracket body 610 may be configured to separate the electric motor mounting portion 620 from the filter mounting portion 630. That is, the electric motor mounting portion 620 and the exhaust filter portion 226 may be respectively located on two opposite sides of the bracket body 610 in a thickness direction. In this way, the electric motor 500 and the exhaust filter portion 226 can be respectively located on the two opposite sides of the bracket body 610 in the thickness direction, so that the electric motor 500 and the exhaust filter portion 226 can be separated by the bracket body 610, position interference of the electric motor 500 and the exhaust filter portion 226 can be avoided, and a structure arrangement is more reasonable.

[0143] In addition, the frame 631 can extend along a circumferential direction of the exhaust filter portion 226, and then, an edge of the exhaust filter portion 226 can be blocked by the frame 631, which is beneficial to improving a protection effect on the exhaust filter portion 226. Moreover, the latch 632 and the bracket body 610 can respectively abut against two opposite sides of the exhaust filter portion 226 in a thickness direction, the bracket body 610 can prevent the exhaust filter portion 226 from excessively extending into the mounting bracket 600, and the latch 632 can prevent the exhaust filter portion 226 from being separated from the mounting bracket 600, so that a connection between the exhaust filter portion 226 and the mounting bracket 600 is more stable and reliable.

[0144] It should be noted that a plurality of latches 632 may be provided, and the plurality of latches 632 are distributed along a circumferential direction of the frame 631 at intervals, and then can be stopped at a plurality of positions of the exhaust filter portion 226 in the circumferential direction, so as to further improve the connection reliability of the exhaust filter portion 226 and the mounting bracket 600, prevent the exhaust filter portion 226 from being separated from the mounting bracket 600, and enable the exhaust filter portion 226 to more stably cover an air inlet side of the second air duct member 220.

[0145] In some embodiments of the present disclosure, as shown in FIG. 28, a side of the frame 631 facing away from the bracket body 610 is provided with a turned edge 633, and the turned edge 633 is bent away from the exhaust filter portion 226.

[0146] By providing the turned edge 633, structural strength of the frame 631 can be improved, and the frame 631 is not easily deformed, so that connection strength of the frame 631 and the exhaust filter portion 226 is higher, and the frame 631 can more reliably fix the exhaust filter portion 226. Moreover, by bending the turned edge 633 away from the exhaust filter portion 226, a position of the turned edge 633 does not interfere with that of the exhaust filter portion 226, thus facilitating assembly of the exhaust filter portion 226 and the mounting bracket 600.

[0147] In some embodiments of the present disclosure, as shown in FIG. 27 and FIG. 28, a side of the electric motor mounting portion 620 facing the exhaust filter portion 226 protrudes from the bracket body 610, and the exhaust filter portion 226 is sandwiched between the electric motor mounting portion 620 and the latch 632.

[0148] For example, the side of the electric motor mounting portion 620 facing the exhaust filter portion 226 protrudes from a side of the bracket body 610 facing the exhaust filter portion 226, which facilitates the electric motor mounting portion 620 and the latch 632 to respectively abut against the two opposite sides of the exhaust filter portion 226 in the thickness direction, so that the exhaust filter portion 226 is positioned more stably, and the exhaust filter portion 226 is prevented from moving.

[0149] It can be understood that the electric motor 500 and the exhaust filter portion 226 are respectively located on the two opposite sides of the bracket body 610, and by causing the side of the electric motor mounting portion 620 facing the exhaust filter portion 226 to protrude from the bracket body 610, the exhaust filter portion 226 can be spaced apart from the bracket body 610 after abutting against the electric motor mounting portion 620, so that the exhaust filter portion 226 and the electric motor 500 can have a larger distance, thus further avoiding position interference of the exhaust filter portion 226 and the blower.

[0150] In some embodiments of the present disclosure, as shown in FIG. 26 and FIG. 29, the electric motor mounting portion 620 includes a base 621 and a plurality of fixing posts 622.

[0151] The base 621 is configured to support one axial end of the electric motor 500, one end of each fixing post 622 is respectively connected to the base 621 and the bracket body 610, the plurality of fixing posts 622 are arranged along a circumferential direction of the electric motor 500, and the electric motor 500 is mounted among the plurality of fixing posts 622.

[0152] For example, a sectional area of an end of the fixing post 622 facing the bracket body 610 may be larger, so that the end of the fixing post 622 facing the bracket body 610 can be conveniently and fixedly connected with the base 621 and the bracket body 610 respectively.

[0153] After the electric motor 500 is mounted on the electric motor mounting portion 620, a stop plate may be connected to an end of the fixing post 622 facing away from the base 621, the stop plate may be stopped at an end of the electric motor 500 facing away from the base 621, and a via hole may be formed in a center of the stop plate, so as to facilitate the output shaft 510 to pass through the stop plate. The stop plate may be a same component as the electric motor pressing plate 540 in the above embodiment.

[0154] In addition, at least three fixing posts 622 may be provided. Thus, the plurality of fixing posts 622 can position the electric motor 500 in a radial direction and prevent the electric motor 500 from radially shifting relative to the electric motor mounting portion 620, and the base 621 and the stop plate may be respectively stopped at two axial ends of the electric motor 500 to fix the electric motor 500 in an axial direction of the electric motor 500, so as to prevent the electric motor 500 from axially shifting.

[0155] In some embodiments of the present disclosure, as shown in FIG. 24 and FIG. 26 to FIG. 29, at least one of the bracket body 610 and the electric motor mounting portion 620 is provided with a first wire passing portion 611, and the filter mounting portion 630 is provided with a second wire passing portion 634. A wire harness 550 of the electric motor 500 sequentially passes through the first wire passing portion 611 and the second wire passing portion 634. The first wire passing portion 611 may be configured as a first wire passing hole, and the second wire passing portion 634 may be configured as a second wire passing hole.

[0156] For example, the first wire passing portion 611 may pass through the bracket body 610 in an axial direction of the mounting bracket 600, and the second wire passing portion 634 may pass through the frame 631 of the filter mounting portion 630 in a radial direction of the mounting bracket 600, so that the wire harness 550 of the electric motor 500 may pass through the first wire passing portion 611 first, and therefore, the wire harness 550 may pass from one side of the bracket body 610 facing the electric motor 500 to the other side of the bracket body 610, and then, the wire harness 550 passes through the second wire passing portion 634, that is, the wire harness 550 may extend to the outside of the mounting bracket 600, so as to facilitate an electrical connection between the wire harness 550 and a power source. Furthermore, after the wire harness 550 passes through the first wire passing portion 611 and the second wire passing portion 634, the mounting bracket 600 may also restrain the wire harness 550, so that the wire harness 550 is routed in the ventilation assembly 200 more regularly and a layout is facilitated.

[0157] In some embodiments of the present disclosure, as shown in FIG. 26 to FIG. 29, the bracket body 610 is provided with a grid 612, and the grid 612 clears the electric motor mounting portion 620. The grid 612 is provided with hollowed portions 613, and at least one of the hollowed portions 613 is configured as the first wire passing portion 611. The hollowed portion 613 may be configured as a grid hole.

[0158] It may be appreciated that the hollowed portion 613 is generally configured to be small. In order to facilitate passing of the wire harness 550 of the electric motor 500, two or more adjacent hollowed portions 613 can be communicated to form the first wire passing portion 611, so that a diameter of the first wire passing portion 611 can be large, the wire harness 550 of the electric motor 500 can pass through the first wire passing portion 611 more easily, and assembly is more convenient.

[0159] In some embodiments of the present disclosure, as shown in FIG. 27 and FIG. 28, the bracket body 610 is provided with a limiting rib 614, and the limiting rib 614 is located on one side of the wire harness 550 to limit the wire harness 550. For example, the limiting rib 614 may be located between the first wire passing portion 611 and the second wire passing portion 634. In this way, when the wire harness 550 extends from the first wire passing portion 611 to the second wire passing portion 634, the limiting rib 614 can restrain the wire harness 550.

[0160] In some examples, a plurality of limiting ribs 614 may be provided. For example, two limiting ribs 614 may be provided. One limiting rib 614 is connected to the bracket body 610 and extends along the axial direction of the bracket body 610, and the wire harness 550 can be located between the limiting rib 614 and the electric motor mounting portion 620, so that the wire harness 550 can be limited by the limiting rib 614 and the electric motor mounting portion 620, and the wire harness 550 is prevented from shifting in the radial direction of the mounting bracket 600. In addition, the other limiting rib 614 may be connected to the side of the electric motor mounting portion 620 facing the exhaust filter portion 226, and the limiting rib 614 may extend in a direction perpendicular to the axial direction of the mounting bracket 600, so that the limiting rib may be stopped by the bracket on a side of the wire harness 550 facing away from the mounting bracket 600. In this way, the bracket body 610, the electric motor mounting portion 620 and the two limiting ribs 614 can be used to limit the wire harness 550 in a plurality of directions and prevent a position of the wire harness 550 from shifting, thereby preventing the position of the wire harness 550 from interfering with positions of other components in the ventilation assembly 200, and facilitating a layout.

[0161] As shown in FIG. 22 to FIG. 29, a cabinet air conditioner according to some embodiments of the present disclosure includes a cabinet 100, a heat exchanger, a heat exchange blower, and a ventilation assembly 200.

[0162] The cabinet 100 has an upper chamber and a lower chamber. The heat exchanger is arranged in the upper chamber, and the heat exchange blower is configured to deliver air subjected to heat exchange with the heat exchanger into a room. The ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into the room, and deliver indoor air to the room or the outside.

[0163] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, an electric motor 500, an exhaust filter portion 226, and a mounting bracket 600.

[0164] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. The exhaust filter portion 226 is arranged on an air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0165] The mounting bracket 600 is connected to the second air duct member 220, and the electric motor 500 and the exhaust filter portion 226 are mounted to the mounting bracket 600.

[0166] Thus, the cabinet 100 is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, the heat exchange blower is configured to deliver the air subjected to heat exchange with the heat exchanger into the room, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0167] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0168] Moreover, the electric motor 500 has the output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510. Thus, the first fan 300 and the second fan 400 can share one electric motor 500, which is beneficial to reducing a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated. Moreover, the exhaust filter portion 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter portion 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving quality of the air entering the cabinet air conditioner, and can improve quality of outlet air of the air conditioner and prevent dust and impurities from entering the cabinet 100.

[0169] In addition, the mounting bracket 600 may be configured to mount both the electric motor 500 and the exhaust filter portion 226. That is, the electric motor 500 and the exhaust filter portion 226 may be mounted on one bracket. Thus, a number of the brackets can be reduced, an integration level of the mounting bracket 600 is higher, assembly is more convenient and faster, and an improvement of an assembly efficiency is facilitated.

[0170] It can be understood that, compared to the related art in which two brackets are provided to fix the electric motor 500 and the exhaust filter portion 226 respectively, in the cabinet air conditioner according to some embodiments of the present disclosure, one bracket may be omitted, thereby saving a set of molds for producing the bracket and facilitating a reduction of a production cost of the mounting bracket 600.

[0171] In the cabinet air conditioner according to some embodiments of the present disclosure, the electric motor 500 and the exhaust filter portion 226 can be simultaneously fixed by the mounting bracket 600, and the cabinet air conditioner has the advantages of a high integration level, convenient assembly, cost saving, or the like.

[0172] In some embodiments of the present disclosure, as shown in FIG. 24 and FIG. 26 to FIG. 29, a first wire passing portion 611 and a second wire passing portion 634 are arranged on the mounting bracket 600, the second wire passing portion 634 is located at an edge of the mounting bracket 600, and a wire harness 550 of the electric motor 500 sequentially passes through the first wire passing portion 611 and the second wire passing portion 634.

[0173] Thus, the wire harness 550 can pass out of the mounting bracket 600 through the second wire passing portion 634, so as to facilitate an electrical connection of the wire harness 550 and a power source, so that the electric motor 500 and the power source can be electrically conducted. Moreover, the wire harness 550 can be fixed through the first wire passing portion 611 and the second wire passing portion 634 of the mounting bracket 600, so that the wire harness 550 is routed in the ventilation assembly 200 more regularly and a layout is facilitated.

[0174] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0175] As shown in FIG. 30 to FIG. 39, a cabinet air conditioner according to some embodiments of the present disclosure includes a body, an adapting assembly 700 and a fresh air inlet pipe 730, and the body includes a cabinet 100, a heat exchanger and a fresh air blower.

[0176] The body includes an upper chamber and a lower chamber located below the upper chamber, a fifth air inlet 160 is formed in the cabinet 100, the heat exchanger is arranged in the upper chamber, and the fresh air blower is arranged in the lower chamber. The fresh air blower drives outdoor air to enter the lower chamber through the fifth air inlet 160. One end of the adapting assembly 700 is communicated with the fifth air inlet 160, the other end of the adapting assembly 700 is communicated with the fresh air inlet pipe 730, and the fresh air inlet pipe 730 and the fifth air inlet 160 are communicated by the adapting assembly 700.

[0177] The adapting assembly 700 includes a first adapter 710 and a second adapter 720, one end of the first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, two ends of the second adapter 720 are respectively connected with the other end of the first adapter 710 and the fresh air inlet pipe 730, and the second adapter 720 is rotatable relative to the first adapter 710 to adjust an included angle between a central axis of the first adapter 710 and a central axis of the second adapter 720.

[0178] The first adapter 710 may be in inserted connection with the cabinet 100 or may be connected thereto by a bolt. For example, the first adapter 710 may be provided with a mounting lug 716, the cabinet 100 may be provided with a bolt hole, and the mounting lug 716 of the first adapter 710 may be connected with the cabinet 100 by the bolt. The second adapter 720 and the fresh air inlet pipe 730 may be in inserted connection. For example, the second adapter 720 may be inserted into the fresh air inlet pipe 730 and in interference fit with the fresh air inlet pipe 730.

[0179] The second adapter 720 is rotatable relative to the first adapter 710, which means that the second adapter 720 can rotate relative to the first adapter 710 along the central axis thereof, or the first adapter 710 can rotate relative to the second adapter 720 along the central axis thereof.

[0180] In the cabinet air conditioner according to some embodiments of the present disclosure, the heat exchanger is arranged in the upper chamber, the fresh air blower is arranged in the lower chamber, the fresh air blower drives the outdoor air to enter the lower chamber from the fifth air inlet 160, one end of the adapting assembly 700 is communicated with the fifth air inlet 160, the other end of the adapting assembly 700 is communicated with the fresh air inlet pipe 730, and the fresh air inlet pipe 730 and the fifth air inlet 160 are communicated by the adapting assembly 700. Thus, the outdoor air may be guided to the fifth air inlet 160 through the fresh air inlet pipe 730 and flow into a room through the fifth air inlet 160 to purify indoor air.

[0181] In addition, the adapting assembly 700 includes the first adapter 710 and the second adapter 720, one end of the first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, and the two ends of the second adapter 720 are respectively connected with the other end of the first adapter 710 and the fresh air inlet pipe 730. Moreover, the second adapter 720 is rotatable relative to the first adapter 710 to adjust the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720.

[0182] In this way, an included angle between the first adapter 710 and the second adapter 720 can be adjusted according to a mounting position of the cabinet air conditioner. That is, by relatively rotating the first adapter 710 and the second adapter 720, an included angle between a central axis of the fresh air inlet pipe 730 and a central axis of the fifth air inlet 160 can be adjusted.

[0183] For example, as shown in FIG. 30, when the fifth air inlet 160 directly faces a wall 740, the first adapter 710 and the second adapter 720 may be relatively rotated to cause the central axis of the first adapter 710 to coincide with the central axis of the second adapter 720. That is, the adapting assembly 700 is linear. Thus, it facilitates the fresh air inlet pipe 730 to pass through the wall 740 to be connected with the fifth air inlet 160 through the adapting assembly 700, and is conducive to reducing an occupied space of the adapting assembly 700. The adapting assembly 700 is not bent, so that an air flow resistance in the adapting assembly 700 is smaller, and the outdoor air can flow more smoothly to the fifth air inlet 160 through the fresh air inlet pipe 730 and the adapting assembly 700, thereby facilitating outdoor fresh air to be introduced into the room.

[0184] When the fifth air inlet 160 is tilted relative to the wall 740, for example, as shown in FIG. 38, the fifth air inlet 160 faces a corner of the wall 740 (that is, when the fresh air inlet pipe 730 is tilted relative to the central axis of the fifth air inlet 160), the first adapter 710 and the second adapter 720 can be relatively rotated to make the adapting assembly 700 have a bent shape. In this way, the central axis of the first adapter 710 may coincide with the central axis of the fifth air inlet 160, so as to facilitate the first adapter 710 to be connected with the cabinet 100 and communicated with the fifth air inlet 160, and the central axis of the second adapter 720 may coincide with the central axis of the fresh air inlet pipe 730, so as to facilitate the second adapter 720 to be connected with the fresh air inlet pipe 730, so that mounting is more convenient and faster, and the occupied space of the adapting assembly 700 may be smaller, which is beneficial to reducing a space required for mounting the cabinet air conditioner.

[0185] Therefore, when the cabinet air conditioner is mounted at different positions, and the fifth air inlet 160 directly faces the wall 740 or is inclined relative to the wall 740, the adapting assembly 700 can be adjusted according to the mounting position of the cabinet air conditioner, so as to change the included angle between the first adapter 710 and the second adapter 720, so that the adapting assembly 700 can adapt to mounting at multiple angles, the connection between the fresh air inlet pipe 730, the adapting assembly 700 and the cabinet 100 is more convenient, the mounting space of the cabinet air conditioner can be saved, and mounting is facilitated.

[0186] Therefore, the cabinet air conditioner according to some embodiments of the present disclosure can meet requirements of different mounting environments, and has the advantages of a high mounting efficiency, convenient mounting, a small mounting space, or the like.

[0187] In some embodiments of the present disclosure, as shown in FIG. 34, one of the first adapter 710 and the second adapter 720 is provided with a second engaging structure 721, the other is provided with a first engaging structure 711, and the second engaging structure 721 is rotatably engaged in the first engaging structure 711. The first engaging structure 711 may be an engaging ring groove, and the second engaging structure 721 may be an engaging ring platform.

[0188] For example, an end of the first adapter 710 facing the second adapter 720 may be provided with the first engaging structure 711, and an end of the second adapter 720 facing the first adapter 710 may be provided with the second engaging structure 721. By engagement of the first engaging structure 711 and the second engaging structure 721, a connection structure is simple, the connection of the first adapter 710 and the second adapter 720 is easy to realize, and the second engaging structure 721 can rotate in the first engaging structure 711, so that the first adapter 710 and the second adapter 720 can rotate relatively, and the first adapter 710 and the second adapter 720 are not prone to separation during the relative rotation.

[0189] Further, as shown in FIG. 32 to FIG. 37, an outer contour of the second engaging structure 721 and an inner contour of the first engaging structure 711 are configured as matched circles.

[0190] Therefore, when the second engaging structure 721 rotates to any angle relative to the first engaging structure 711, an outer circumferential surface of the second engaging structure 721 and an inner circumferential surface of the first engaging structure 711 can be attached, so that the second engaging structure 721 can be stably engaged in the first engaging structure 711, the inner circumferential surface of the first engaging structure 711 and the second engaging structure 721 can be prevented from rotating and interfering with each other, and therefore, the relative rotation of the first adapter 710 and the second adapter 720 is easier.

[0191] In some embodiments of the present disclosure, as shown in FIG. 36 and FIG. 37, a central axis of the second engaging structure 721 and the central axis of one of the first adapter 710 and the second adapter 720 form a first inclination angle, and a central axis of the first engaging structure 711 and the central axis of the other of the first adapter 710 and the second adapter 720 form a second inclination angle. A difference between the first inclination angle and the second inclination angle is A, and A satisfies the following condition: -10°≤A≤10°.

[0192] For example, the first engaging structure 711 may be arranged on the first adapter 710, and the second engaging structure 721 may be arranged on the second adapter 720. As shown in FIG. 36, an included angle between the central axis of the first adapter 710 and the central axis of the first engaging structure 711 is C, that is, the second inclination angle is C; as shown in FIG. 37, an included angle between the central axis of the second adapter 720 and the central axis of the second engaging structure 721 is B, that is, the first inclination angle is B.

[0193] The first inclination angle may be equal to the second inclination angle. In this way, by enabling the first adapter 710 and the second adapter 720 to rotate relatively, the central axis of the first adapter 710 and the central axis of the second adapter 720 can coincide with each other. That is, when the first adapter 710 and the second adapter 720 are rotated to extreme positions, the adapting assembly 700 may be linear, so that the fresh air inlet pipe 730 and the fifth air inlet 160 are connected through the adapting assembly 700 under the condition that the fresh air inlet pipe 730 directly faces the fifth air inlet 160.

[0194] Certainly, there may be a difference between the first inclination angle and the second inclination angle. For example, the first inclination angle may be greater than the second inclination angle, and the difference between the first inclination angle and the second inclination angle is 0° to 10°. Alternatively, the first inclination angle may be less than the second inclination angle, and the difference between the first inclination angle and the second inclination angle is -10° to 0°.

[0195] Therefore, a pressing force can exist between the second engaging structure 721 and the first engaging structure 711, which is beneficial to improving a sealing performance between the second engaging structure 721 and the first engaging structure 711. Moreover, the difference between the first inclination angle and the second inclination angle is not too large, so as to avoid that a bending angle between the first adapter 710 and the second adapter 720 is too small during the relative rotation of the first adapter 710 and the second adapter 720, and then ensure that the air flow resistance in the adapting assembly 700 is small, and the outdoor air flows in the adapting assembly 700 more smoothly.

[0196] It may be appreciated that the second engaging structure 721 and the first engaging structure 711 always remain engaged when the first adapter 710 and the second adapter 720 rotate relatively. That is, it can be considered to indicate that the first adapter 710 rotates relative to the second adapter 720 along the central axis of the first engaging structure 711, or the second adapter 720 rotates relative to the first adapter 710 along the central axis of the second engaging structure 721, so that the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 can be adjusted to adjust the adapting assembly 700 to be linear or bent, and the bending angle of the adapting assembly 700 can be adjusted according to the mounting position of the cabinet air conditioner.

[0197] In some embodiments of the present disclosure, as shown in FIG. 35, the first engaging structure 711 includes an abutting portion 712, a body portion 713, and an engaging portion 714.

[0198] A plane of the abutting portion 712 is perpendicular to the central axis of the first engaging structure 711, and the second engaging structure 721 abuts against the abutting portion 712. The body portion 713 is connected to the abutting portion 712 and surrounds the second engaging structure 721, and the engaging portion 714 is connected to the body portion 713 and protrudes from an inner circumferential surface of the body portion 713. The second engaging structure 721 is engaged between the abutting portion 712 and the engaging portion 714.

[0199] Therefore, when the second engaging structure 721 is inserted into the first engaging structure 711, an end of the second engaging structure 721 facing the first engaging structure 711 can abut against the abutting portion 712. The abutting portion 712 can limit an insertion position of the second engaging structure 721 to prevent an inserted connection size of the first adapter 710 and the second adapter 720 from being too large, and the engaging portion 714 can be engaged on a side of the second engaging structure 721 facing away from the abutting portion 712, so that the position of the second engaging structure 721 can be fixed by the engaging portion 714 and the abutting portion 712, the first adapter 710 and the second adapter 720 can be connected more stably, and the first adapter 710 and the second adapter 720 are prevented from being separated.

[0200] Moreover, the body portion 713 may surround the second engaging structure 721 from the outer circumferential surface of the second engaging structure 721. On the one hand, a contact area of the second engaging structure 721 and the first engaging structure 711 can be increased, so that connection strength of the second engaging structure 721 and the first engaging structure 711 is higher, and the connection between the first adapter 710 and the second adapter 720 is more stable and reliable. On the other hand, the second engaging structure 721 can be limited in a radial direction by the body portion 713, so that radial dislocation of the first adapter 710 and the second adapter 720 can be avoided, and a structure arrangement is more reasonable.

[0201] In some embodiments of the present disclosure, as shown in FIG. 35, the engaging portions 714 are a plurality of latches 632, and the plurality of latches 632 are arranged at intervals along a circumference of the body portion 713.

[0202] For example, the plurality of latches 632 are arranged at an end of the body portion 713 away from the abutting portion 712, and the latches 632 protrude from an inner circumferential surface of the body portion 713. Thus, after the second engaging structure 721 is inserted into the first engaging structure 711, the plurality of latches 632 can abut against the second engaging structure 721 at a plurality of positions along a circumference of the second engaging structure 721, so that the second engaging structure 721 is prevented from being separated from the first engaging structure 711, and then, the first adapter 710 and the second adapter 720 can be prevented from being separated from each other.

[0203] In addition, by providing the plurality of latches 632, connection stability of the first engaging structure 711 and the second engaging structure 721 can be improved, and the second engaging structure 721 is engaged by the plurality of latches 632 simultaneously, so that connection failure of the first engaging structure 711 and the second engaging structure 721 caused by connection failure of a single latch 632 can be avoided, and connection reliability of the first adapter 710 and the second adapter 720 is further improved.

[0204] In some embodiments of the present disclosure, as shown in FIG. 35, the body portion 713 is provided with a plurality of deformation portions 715, and the plurality of deformation portions 715 are respectively arranged on two opposite sides of the latches 632.

[0205] The arrangement of the deformation portion 715 can weaken structural strength of the body portion 713 on the two sides of the latch 632, so that when the second engaging structure 721 is inserted into the first engaging structure 711, the latch 632 can be elastically deformed more easily, and therefore, the first adapter 710 and the second adapter 720 can be mounted more easily, the mounting is more convenient and faster, and the engaging portion 714 and the second engaging structure 721 can be prevented from being damaged in the mounting process.

[0206] In some embodiments of the present disclosure, the second adapter 720 has a first position and a second position. When the second adapter 720 is located at the first position, the central axis of the second adapter 720 coincides with the central axis of the first adapter 710. When the second adapter 720 is located at the second position, the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is α, and α satisfies the following condition: 90°≤α≤135°.

[0207] That is, the relative rotation of the second adapter 720 and the first adapter 710 have two extreme positions. When the second adapter 720 is located at the first position, that is, the second adapter 720 and the first adapter 710 relatively rotate to the first extreme position, the adapting assembly 700 may be linear. When the second adapter 720 is located at the second position, that is, the second adapter 720 and the first adapter 710 relatively rotate to the second extreme position, the adapting assembly 700 may be bent, and the included angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is between 90° and 135°. Thus, the second adapter 720 can rotate between the first position and the second position, so that the bending angle of the adapting assembly 700 can be adjusted.

[0208] Moreover, since 90°≤α≤135°, the first adapter 710 and the second adapter 720 can rotate relatively according to the mounting position of the cabinet air conditioner, so that the included angle between the first adapter 710 and the second adapter 720 can be proper by rotation, and the adapting assembly 700 can be conveniently connected with the fresh air inlet pipe 730 and the cabinet 100 respectively.

[0209] In some other embodiments of the present disclosure, as shown in FIG. 30 to FIG. 39, the adapting assembly 700 includes a first adapter 710 and a second adapter 720.

[0210] The first adapter 710 is connected with the cabinet 100 and communicated with the fifth air inlet 160, the second adapter 720 is connected with the fresh air inlet pipe 730, and an extending direction of the second adapter 720 is adjustable relative to an extending direction of the first adapter 710.

[0211] Thus, when the fifth air inlet 160 directly faces the wall 740, the central axis of the fresh air inlet pipe 730 may coincide with the central axis of the fifth air inlet 160, and in this case, the extending direction of the first adapter 710 and the extending direction of the second adapter 720 may be adjusted to extend in a same direction. That is, the adapting assembly 700 may be linear, so as to facilitate the connection between the first adapter 710 and the cabinet 100 and the connection between the second adapter 720 and the fresh air inlet pipe 730.

[0212] When the fifth air inlet 160 obliquely faces the wall 740, the central axis of the fresh air inlet pipe 730 may be inclined relative to the central axis of the fifth air inlet 160. In this case, the extending direction of the first adapter 710 and the extending direction of the second adapter 720 may be adjusted to be relatively inclined. That is, the adapting assembly 700 may be bent, so that the extending direction of the first adapter 710 may coincide with the central axis of the fifth air inlet 160, and the extending direction of the second adapter 720 may coincide with the central axis of the fresh air inlet pipe, which facilitates the connection between the first adapter 710 and the cabinet 100 and the connection between the second adapter 720 and the fresh air inlet pipe 730, and is beneficial to reducing the occupied space of the adapting assembly 700, so that the mounting space of the cabinet air conditioner may be smaller.

[0213] The cabinet air conditioner according to some embodiments of the present disclosure can meet requirements of different mounting environments, and has the advantages of a high mounting efficiency, convenient mounting, a small mounting space, or the like.

[0214] In some embodiments of the present disclosure, the first adapter 710 is provided with a second engaging structure 721, the central axis of the first adapter 710 is perpendicular to a first section, a central axis of the second engaging structure 721 is perpendicular to a second section, an included angle between the first section and the second section is β, and β satisfies the following condition: 10°≤β≤45°.

[0215] In this way, there may be an angular difference between the central axis of the first adapter 710 and the central axis of the second engaging structure 721, and when the second engaging structure 721 rotates relative to the second adapter 720, the first adapter 710 may be driven to rotate. The first adapter 710 may be bent in different directions relative to the second adapter 720, so that an angular difference between the first adapter 710 and the second adapter 720 may be adjusted to enable the first adapter 710 and the second adapter 720 to form a linear shape or a bent shape with different angles.

[0216] Moreover, since 10°≤β≤45°, on the one hand, the included angle between the first section and the second section can be prevented from being too small, so that the included angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721 can be large, and during the rotation of the second engaging structure 721 relative to the second adapter 720, a change range of the included angle between the first adapter 710 and the second adapter 720 can be large, so as to adjust the shape of the adapting assembly 700 to enable the cabinet air conditioner to satisfy requirements of different mounting environments. On the other hand, the included angle between the first section and the second section can be prevented from being too large, so that it can be avoided that during rotation of the second engaging structure 721 relative to the second adapter 720, the first adapter 710 is excessively bent relative to the second adapter 720, air flow in the adapting assembly 700 can be kept smooth, and it can be avoided that structural strength of the first adapter 710 and the second engaging structure 721 is lowered due to the excessively large included angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721, so as to ensure that overall structural strength of the adapting assembly 700 may be high.

[0217] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0218] As shown in FIG. 40 to FIG. 51, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, and a ventilation assembly 200.

[0219] The body has an upper chamber and a lower chamber located below the upper chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into a room, and deliver indoor air to the room or the outside.

[0220] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0221] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside. The second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510.

[0222] One of the first fan 300 and the second fan 400 is provided with a first rotation stopping portion 320, the other is provided with a second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at a same frequency.

[0223] In the cabinet air conditioner according to some embodiments of the present disclosure, the body is provided with the upper chamber and the lower chamber, the heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0224] The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside. The second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0225] Moreover, the electric motor 500 has the single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated.

[0226] In addition, one of the first fan 300 and the second fan 400 is provided with the first rotation stopping portion 320, the other is provided with the second rotation stopping portion 420, and the first rotation stopping portion 320 fits the second rotation stopping portion 420. When the electric motor 500 works, the electric motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first rotation stopping portion 320 fits the second rotation stopping portion 420 to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0227] It should be noted that the first rotation stopping portion 320 fits the second rotation stopping portion 420 to stop rotation of the second fan 400 and the first fan 300 in a circumferential direction of the output shaft 510. That is, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Moreover, the first rotation stopping portion 320 fits the second rotation stopping portion 420 to position the assembly of the second fan 400 and the first fan 300.

[0228] Therefore, even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first rotation stopping portion 320 fits the second rotation stopping portion 420, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and the rotation speed of the second fan 400 is lower than that of the first fan 300. After the first rotation stopping portion 320 fits the second rotation stopping portion 420, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0229] Thus, in the cabinet air conditioner according to some embodiments of the present disclosure, the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the vibration and noise and improving the use effect of the air conditioner.

[0230] In some embodiments of the present disclosure, as shown in FIG. 44 and FIG. 45, a side of the first fan 300 facing the second fan 400 is provided with a first hub 330, and the first hub 330 protrudes towards the second fan 400 to form a first fitting portion 340.

[0231] As shown in FIG. 47 and FIG. 48, a second hub 430 is arranged on a side of the second fan 400 facing the first fan 300, and the second hub 430 is recessed towards the first fan 300 to form a second fitting portion 440. One of the first fitting portion 340 and the second fitting portion 440 is provided with the first rotation stopping portion 320, and the other is provided with the second rotation stopping portion 420.

[0232] That is, the first fitting portion 340 may be provided with the first rotation stopping portion 320, and the second fitting portion 440 may be provided with the second rotation stopping portion 420; alternatively, the first fitting portion 340 may be provided with the second rotation stopping portion 420, and the second fitting portion 440 may be provided with the first rotation stopping portion 320.

[0233] By causing the first fitting portion 340 to protrude towards the second fan 400 and recessing the second fitting portion 440 towards the first fan 300, the first fitting portion 340 and the second fitting portion 440 can be closer to each other, so that the first fitting portion 340 and the second fitting portion 440 can be conveniently in contact fit, the first rotation stopping portion 320 and the second rotation stopping portion 420 can be stably and reliably fitted together, the first rotation stopping portion 320 and the second rotation stopping portion 420 are prevented from being separated, and then, the second fan 400 and the first fan 300 can be ensured to rotate at the same frequency, so as to reduce the vibration and noise of the cabinet air conditioner.

[0234] Further, as shown in FIG. 46 and FIG. 49, the first rotation stopping portions 320 are a plurality of rotation stopping protrusions, the plurality of rotation stopping protrusions are arranged along a circumferential direction of the first fitting portion 340, the second rotation stopping portions 420 are a plurality of rotation stopping grooves, the plurality of rotation stopping grooves are arranged along a circumferential direction of the second fitting portion 440, and the plurality of rotation stopping protrusions are inserted into the plurality of rotation stopping grooves in a one-to-one correspondence manner.

[0235] By providing the plural rotation stopping protrusions and the plural rotation stopping grooves, the rotation stopping protrusions and the rotation stopping grooves can be fitted more stably and reliably, connection failure of the second fan 400 and the first fan 300 is avoided, rotation synchronism of the second fan 400 and the first fan 300 is effectively guaranteed, rotation noise and rotation vibration of the second fan 400 and the first fan 300 are smaller, and the use effect of the air conditioner is improved.

[0236] Further, the first rotation stopping portion 320 and the second rotation stopping portion 420 are configured as the protrusion and the groove fitting each other, which is conducive to simplifying structures of the first rotation stopping portion 320 and the second rotation stopping portion 420 to facilitate processing and manufacturing, and can simplify assembly of the second fan 400 and the first fan 300, and when the second fan 400 and the first fan 300 are assembled in place along a circumferential direction of the output shaft 510, the rotation stopping protrusion can be inserted into the rotation stopping groove, resulting in a higher assembly efficiency.

[0237] It can be understood that the first rotation stopping portion 320 and the second rotation stopping portion 420 may have other fitting structures. For example, the first rotation stopping portion 320 and the second rotation stopping portion 420 can be configured as protrusions, and the protrusions on the first fitting portion 340 and the protrusions on the second fitting portion 440 are staggered in a circumferential direction, so that the protrusions on the first fitting portion 340 and the protrusions on the second fitting portion 440 can abut against each other, and thus, the two fans can rotate at the same frequency.

[0238] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, the rotation stopping protrusion has a first side 321 and a second side 322 opposite to each other in the circumferential direction of the first fitting portion 340, and the first side 321 and the second side 322 get close to each other along an axial direction of the first fitting portion 340 towards the rotation stopping groove. The rotation stopping groove has a first wall 421 and a second wall 422 opposite to each other in the circumferential direction of the second fitting portion 440, and away from the rotation stopping protrusion in an axial direction of the second fitting portion 440, the first wall 421 and the second wall 422 are close to each other.

[0239] That is, the first side 321 and the second side 322 may be configured as slopes, and the first wall 421 and the second wall 422 may also be configured as slopes. It should be noted that an inclination angle of the first side 321 and an inclination angle of the first wall 421 may be the same, and an inclination angle of the second side 322 and an inclination angle of the second wall 422 may be the same.

[0240] Thus, after the rotation stopping protrusion is inserted into the rotation stopping groove, the first side 321 and the second wall 422 can abut against each other and have a large contact area, and the second side 322 and the second wall 422 can abut against each other and have a large contact area. Thus, attachment of the rotation stopping protrusion and the rotation stopping groove can be tighter, fitting stability of the rotation stopping protrusion and the rotation stopping groove is further improved, the second fan 400 and the first fan 300 are ensured not to rotate or shake relatively, and the vibration and rotation noise of the second fan 400 and the first fan 300 are more effectively reduced.

[0241] Furthermore, with this arrangement, a width of an end of the rotation stopping protrusion away from the first fitting portion 340 may be small, and an opening width of the rotation stopping groove may be large, so as to facilitate the insertion of the rotation stopping protrusion into the rotation stopping groove. That is, the rotation stopping protrusion and the rotation stopping groove can guide the assembly of the second fan 400 and the first fan 300, which is conducive to simplifying the assembly of the second fan 400 and the first fan 300, and an assembly efficiency is higher.

[0242] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, the first side 321 and the second side 322 get away from each other in a radial direction of the first fitting portion 340 outwards. The first wall 421 and the second wall 422 get away from each other in a radial direction of the second fitting portion 440 outwards.

[0243] It can be understood that, in the radial direction of the first fitting portion 340, the closer to a central axis of the first fitting portion 340, the smaller a radius of the first fitting portion 340, the smaller a space for arranging the rotation stopping protrusion in the circumferential direction. In the radial direction of the first fitting portion 340 outwards, the radius of the first fitting portion 340 is increased, the space for arranging the rotation stopping protrusion in the circumferential direction is also increased, and a distance between the first side 321 and the second side 322 is increased. Thus, the rotation stopping protrusions can make full use of the space on the first fitting portion 340, and the adjacent rotation stopping protrusions can be prevented from being too close to each other, so that a layout is more reasonable.

[0244] Similarly, in the radial direction of the second fitting portion 440, the closer to a central axis of the second fitting portion 440, the smaller a radius of the second fitting portion 440, the smaller a space for arranging the rotation stopping groove in the circumferential direction. In the radial direction of the second fitting portion 440 outwards, the radius of the second fitting portion 440 is increased, the space for arranging the rotation stopping groove in the circumferential direction is also increased, and a distance between the first wall 421 and the second wall 422 is increased. Thus, the rotation stopping grooves can make full use of the space on the second fitting portion 440, and the adjacent rotation stopping grooves can be prevented from being too close to each other, so that a layout is more reasonable.

[0245] Moreover, the first side 321 and the second side 322 may also be configured as slopes in the radial direction of the first fitting portion 340, and the first wall 421 and the second wall 422 may also be configured as slopes in the radial direction of the second fitting portion 440. Thus, a contact area of the first side 321 and the first wall 421 is further increased, a contact area of the second side 322 and the second wall 422 is further increased, the rotation stopping protrusion and the rotation stopping groove are more closely fitted, and connection stability of the first fan 300 and the second fan 400 is higher.

[0246] In some embodiments of the present disclosure, as shown in FIG. 46 and FIG. 49, a side of the rotation stopping protrusion away from a center of the first fitting portion 340 is configured as a third side 323, and the third side 323 is inclined towards the center of the first fitting portion 340 towards the rotation stopping groove in the axial direction of the first fitting portion 340. A side of the rotation stopping groove away from a center of the second fitting portion 440 is configured as a third wall 423, and away from the rotation stopping protrusion in the axial direction of the second fitting portion 440, the third wall 423 is inclined towards the center of the second fitting portion 440.

[0247] That is, the third side 323 may be configured as a slope, and the third wall 423 may be configured as a slope. Thus, a contact area of the third side 323 and the third wall 423 is also large. After the rotation stopping protrusion is inserted into the rotation stopping groove, the third side 323 and the third wall 423 can abut against each other, attachment of the rotation stopping protrusion and the rotation stopping groove can be tighter, the fitting stability of the rotation stopping protrusion and the rotation stopping groove is further improved, the second fan 400 and the first fan 300 are ensured not to rotate or shake relatively, and the vibration and rotation noise of the second fan 400 and the first fan 300 are more effectively reduced.

[0248] Moreover, the third side 323 fits the third wall 423 to guide the fitting of the rotation stopping protrusion and the rotation stopping groove, so as to guide the assembly of the second fan 400 and the first fan 300, which is beneficial to simplifying the assembly of the second fan 400 and the first fan 300, resulting in the higher assembly efficiency.

[0249] In some embodiments of the present disclosure, as shown in FIG. 50 and FIG. 51, the first fan 300 further includes a first insert 350. The first insert 350 is fixed in the first hub 330, and the output shaft 510 is sleeved with the first insert 350 which is in transmission connection with the output shaft 510. The second fan 400 further includes a second insert 450, the second insert 450 is fixed in the second hub 430, and the output shaft 510 is sleeved with the second insert 450 which is in transmission connection with the output shaft 510.

[0250] The first insert 350 may be molded by injection and arranged within the first hub 330, and hardness of the first insert 350 may be greater than hardness of the first hub 330. Thus, fitting stability of the first fan 300 and the output shaft 510 can be improved, a gap between the first insert 350 and the output shaft 510 can be small, and the output shaft 510 can more stably drive the first fan 300 to rotate. In addition, the second insert 450 may be molded by injection and arranged in the second hub 430, and hardness of the second insert 450 may be greater than that of the second hub 430, so that fitting stability of the second fan 400 and the output shaft 510 may be improved, a gap between the second insert 450 and the output shaft 510 may be small, and the output shaft 510 may more stably drive the second fan 400 to rotate.

[0251] Further, as shown in FIG. 51, an outer contour of the output shaft 510 is non-circular, the first insert 350 is provided with a first rotation preventing portion 351 adapted to the outer contour of the output shaft 510, the second insert 450 is provided with a second rotation preventing portion 451 adapted to the outer contour of the output shaft 510, and the output shaft 510 is arranged through the first rotation preventing portion 351 and the second rotation preventing portion 451.

[0252] The first rotation preventing portion 351 may be configured as a first rotation stopping hole, and the second rotation preventing portion 451 may be configured as a second rotation stopping hole.

[0253] Thus, after the output shaft 510 is arranged through the first rotation preventing portion 351, the output shaft 510 and the first insert 350 do not rotate relative to each other. That is, the output shaft 510 and the first fan 300 do not rotate relative to each other, so that the first fan 300 can be driven to rotate by the output shaft 510.

[0254] Moreover, after the output shaft 510 is arranged through the second rotation preventing portion 451, the output shaft 510 and the second insert 450 also do not rotate relative to each other. That is, the output shaft 510 and the second fan 400 do not rotate relative to each other, so that the second fan 400 can be driven to rotate by the output shaft 510.

[0255] It can be understood that, for the convenience of assembly, a certain gap may exist between the output shaft 510 and the first rotation preventing portion 351, a certain gap may exist between the output shaft 510 and the second rotation preventing portion 451, and when the output shaft 510 drives the first fan 300 and the second fan 400 to rotate, the first fan 300 and the second fan 400 may shake relatively, and in some embodiments of the present disclosure, after the second fan 400 and the first fan 300 are connected and positioned by the first rotation stopping portion 320 and the second rotation stopping portion 420, the second fan 400 and the first fan 300 may not rotate relatively or a relative rotation amplitude is small, so that rotation noise and rotation vibration of the second fan 400 and the first fan 300 may be reduced, and the use effect of the air conditioner may be improved.

[0256] As shown in FIG. 40 to FIG. 51, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, and a ventilation assembly 200.

[0257] The body has an upper chamber and a lower chamber located below the upper chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver outdoor air into a room, and deliver indoor air to the room or the outside.

[0258] The ventilation assembly 200 includes a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0259] For example, the body is provided with the upper chamber and the lower chamber. The heat exchanger is arranged in the upper chamber, the ventilation assembly 200 is arranged in the lower chamber, and the ventilation assembly 200 is configured to deliver the outdoor air into the room, and deliver the indoor air to the room or the outside. Thus, the ventilation assembly 200 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the ventilation assembly 200 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the ventilation assembly 200 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0260] The first air duct member 210 is arranged in the lower chamber, a first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. Thus, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0261] Moreover, the electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the ventilation assembly 200 is facilitated.

[0262] In addition, the first fan 300 and the second fan 400 are connected to rotate at a same frequency.

[0263] Therefore, the second fan 400 and the first fan 300 do not rotate relatively, and the second fan 400 and the first fan 300 can rotate at the same frequency with the output shaft 510. Even if the first fan 300 and the second fan 400 are subjected to different air resistances, after the first fan 300 and the second fan 400 are connected, the fan with a higher rotation speed can drive the fan with a lower rotation speed to rotate, and meanwhile, the fan with a higher rotation speed is influenced by the fan with a lower rotation speed to reduce the rotation speed. For example, the air resistance of the second fan 400 is larger, the air resistance of the first fan 300 is smaller, and in this case, the rotation speed of the second fan 400 is lower than that of the first fan 300, and after the first fan 300 and the second fan 400 are connected, the first fan 300 can drive the second fan 400 to rotate in an accelerated manner, and meanwhile, the first fan 300 is influenced by the second fan 400 to reduce the rotation speed, so that the first fan 300 and the second fan 400 can keep consistent rotation speeds. The first fan 300 and the second fan 400 can rotate at the same frequency, which is conducive to reducing rotation noise and rotation vibration of the first fan 300 and the second fan 400, and improves a use effect of the air conditioner.

[0264] In the cabinet air conditioner according to some embodiments of the present disclosure, the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the vibration and noise and improving the use effect of the air conditioner.

[0265] In some embodiments of the present disclosure, as shown in FIG. 42, FIG. 46 and FIG. 49, a rotation stopping protrusion is arranged on a side of the first fan 300 facing the second fan 400, a rotation stopping groove is formed in a side of the second fan 400 facing the first fan 300, and the rotation stopping protrusion is inserted into the rotation stopping groove.

[0266] The connection of the first fan 300 and the second fan 400 is configured as fitting of the protrusion and the groove, which is conducive to simplifying a connection structure of the first fan 300 and the second fan 400 to facilitate processing and manufacturing, and can simplify the assembly of the second fan 400 and the first fan 300. When the second fan 400 and the first fan 300 are assembled in place along a circumferential direction of the output shaft 510, the rotation stopping protrusion can be inserted into the rotation stopping groove, the first fan 300 and the second fan 400 are connected, and an assembly efficiency of the first fan 300 and the second fan 400 is higher.

[0267] Moreover, after the rotation stopping protrusion is inserted into the rotation stopping groove, a side of the rotation stopping protrusion can abut against a wall of the rotation stopping groove, and the rotation stopping protrusion and the rotation stopping groove cannot rotate relatively, so that the same-frequency rotation of the first fan 300 and the second fan 400 can be realized.

[0268] A cabinet air conditioner according to some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0269] As shown in FIG. 52 to FIG. 58, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0270] The heat exchanger is arranged in an upper chamber, the first air duct member 210 is arranged in a lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor air enters a room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, so as to drive the first fan 300 and the second fan 400 to rotate synchronously.

[0271] One of the first air duct member 210 and the second air duct member 220 is provided with an air duct member fixing portion 227, and a free end of the output shaft 510 is rotatably mounted to the air duct member fixing portion 227.

[0272] Lubricating oil may be applied to a joint between the free end of the output shaft 510 and the air duct member fixing portion 227 to make the output shaft 510 rotate more easily and reduce noise of the output shaft 510 during rotation.

[0273] In the cabinet air conditioner according to some embodiments of the present disclosure, the body is provided with the upper chamber and the lower chamber, and the heat exchanger is arranged in the upper chamber. The first air duct member 210 is arranged in the lower chamber, the first air duct 201 is formed in the first air duct member 210, and the outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, the second air duct 202 is formed in the second air duct member 220, and the indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room.

[0274] Thus, the second fan 400 can introduce the outdoor air into the room through the first air duct 201, and then can purify the indoor air through the outdoor fresh air. Alternatively, the first fan 300 may discharge the indoor air to the outside, and thus may discharge indoor dirty air to the outside, so as to rapidly purify the indoor air after introducing the outdoor air. Alternatively, the first fan 300 may suck the indoor air into the cabinet 100, and the indoor air exchanges heat with the heat exchanger and is then discharged into the room, so that indoor cooling or heating may be rapidly realized.

[0275] Meanwhile, the first air duct member 210 can guide the outdoor fresh air, and the second air duct member 220 can guide the indoor air, so that the outdoor fresh air and the indoor air can flow separately, interference between the outdoor air and the indoor air during flowing is avoided, and an air stream in the cabinet air conditioner can flow more smoothly.

[0276] The electric motor 500 has the single output shaft 510, and the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, so as to drive the first fan 300 and the second fan 400 to rotate synchronously. That is, the first fan 300 and the second fan 400 can share one electric motor 500, which can reduce a number of the electric motors 500, so that a number of parts of the cabinet air conditioner is smaller, assembly is more convenient, an occupied space of the electric motor 500 can be reduced, and a reduction of a volume of the cabinet air conditioner is facilitated.

[0277] In addition, one of the first air duct member 210 and the second air duct member 220 is provided with the air duct member fixing portion 227, and the free end of the output shaft 510 is rotatably mounted to the air duct member fixing portion 227.

[0278] For example, the electric motor 500 may be arranged in the first air duct member 210, and the output shaft 510 of the electric motor 500 extends towards the second air duct member 220. In this case, the second air duct member 220 may be provided with the air duct member fixing portion 227, and an end of the output shaft 510 away from the electric motor 500 (i.e., the free end of the output shaft 510) may be mounted on the air duct member fixing portion 227 of the second air duct member 220. Alternatively, the electric motor 500 may be arranged in the second air duct member 220, and the output shaft 510 of the electric motor 500 extends towards the first air duct member 210. In this case, the first air duct member 210 may be provided with the air duct member fixing portion 227, and the end of the output shaft 510 away from the electric motor 500 (i.e., the free end of the output shaft 510) may be mounted on the air duct member fixing portion 227 of the first air duct member 210. In this way, a structure of the first air duct member 210 and a structure of the second air duct member 220 may be configured according to a layout of the electric motor 500, so as to ensure that the free end of the output shaft 510 can be mounted on the air duct member fixing portion 227, and prevent a position of the air duct member fixing portion 227 from interfering with a position of the electric motor 500 or another component.

[0279] Furthermore, by connecting the free end of the output shaft 510 with the air duct member fixing portion 227, the free end of the output shaft 510 can be fixedly connected with the first air duct member 210 or the second air duct member 220, and the first air duct member 210 or the second air duct member 220 can support the free end of the output shaft 510, thereby improving rotation stability of the output shaft 510. The output shaft 510 is not prone to shake, so that vibration of the output shaft 510 during rotation and noise generated by the vibration can be greatly reduced, vibration and noise during operation of the cabinet air conditioner are smaller, and a use effect of the air conditioner is improved.

[0280] In this way, in the cabinet air conditioner according to some embodiments of the present disclosure, support of the output shaft 510 of the electric motor 500 can be enhanced, the rotation of the output shaft 510 is more stable, and the vibration and rotation noise are smaller, thereby improving the use effect of the air conditioner.

[0281] In some embodiments of the present disclosure, as shown in FIG. 53, the air duct member fixing portion 227 extends in an axial direction of one of the first fan 300 and the second fan 400, and the air duct member fixing portion 227 is provided to protrude towards the output shaft 510.

[0282] For example, the first air duct member 210 is provided with the air duct member fixing portion 227, and the air duct member fixing portion 227 extends in the axial direction of the first fan 300. If the second air duct member 220 is provided with the air duct member fixing portion 227, the air duct member fixing portion 227 extends along the axial direction of the second fan 400. This arrangement facilitates the free end of the output shaft 510 to be mounted on the air duct member fixing portion 227, assembly is more convenient, and a blocking area of the air duct member fixing portion 227 in a radial direction of the first air duct member 210 or the second air duct member 220 may be small, so that the air duct member fixing portion 227 can be prevented from excessively blocking an air inlet, so as to facilitate the indoor air to enter the first air duct member 210, or facilitate the outdoor fresh air to enter the second air duct member 220.

[0283] In addition, the air duct member fixing portion 227 protrudes towards the output shaft 510, that is, the air duct member fixing portion 227 protrudes from the first air duct member 210 or the second air duct member 220. Thus, the air duct member fixing portion 227 may be closer to the free end of the output shaft 510, so as to facilitate the output shaft 510 to be inserted into the air duct member fixing portion 227, and assembly is more convenient.

[0284] In some embodiments of the present disclosure, as shown in FIG. 53, a central axis of the air duct member fixing portion 227 and a central axis of the output shaft 510 coincide. Thus, the air duct member fixing portion 227 and the output shaft 510 may coincide, and the free end of the output shaft 510 may be inserted into the air duct member fixing portion 227 to support the output shaft 510 through the air duct member fixing portion 227, so that rotation of the output shaft 510 is more stable. Moreover, the air duct member fixing portion 227 and the output shaft 510 are not staggered in a radial direction of the output shaft 510, which can simplify assembly of the output shaft 510 and the air duct member fixing portion 227, and can reduce a space occupied by the output shaft 510 and the air duct member fixing portion 227 in the radial direction of the first air duct member 210 or the second air duct member 220, thereby facilitating a layout and avoiding position interference of components.

[0285] In addition, in some embodiments, as shown in FIG. 53, an outer diameter of the air duct member fixing portion 227 may be reduced towards the output shaft 510 in an axial direction of the air duct member fixing portion 227. Thus, an outer diameter of a joint of the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 may be large, connection strength of the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 is higher, stability of the air duct member fixing portion 227 is better, and the air duct member fixing portion 227 is not prone to shake. Thus, the air duct member fixing portion 227 can more reliably support the free end of the output shaft 510, so that the rotation of the output shaft 510 can be more stable, the rotation vibration and noise of the output shaft 510 can be small, and the use effect of the air conditioner can be improved.

[0286] In some embodiments of the present disclosure, as shown in FIG. 57, the output shaft 510 includes a transmission section 511, an output shaft fixing section 512, and a support section 513. The output shaft fixing portion 512 may be a threaded section.

[0287] The transmission section 511 is sleeved with the first fan 300 and the second fan 400 which are in transmission connection with the transmission section 511, one end of the output shaft fixing portion 512 is connected with the transmission section 511, and a fastener 520 is arranged on the output shaft fixing portion 512. The first fan 300 and the second fan 400 are stopped between the electric motor 500 and the fastener 520, the support section 513 is connected with the other end of the output shaft fixing portion 512, and the support section 513 is rotatably inserted into the air duct member fixing portion 227.

[0288] An outer contour of the transmission section 511 may be configured to be non-circular, so that after the transmission section 511 is sleeved with the first fan 300 and the second fan 400, the transmission section 511 can drive the second fan 400 and the first fan 300 to rotate.

[0289] Additionally, the fastener 520 may be a nut. After the transmission section 511 is sleeved with the first fan 300 and the second fan 400, the nut can be in screwed connection with the output shaft fixing portion 512, so that the first fan 300 and the second fan 400 can be limited by the fastener 520, the transmission section 511 can be more stably sleeved with the first fan 300 and the second fan 400, the first fan 300 and the second fan 400 are prevented from shifting, and the vibration and noise generated during rotation of the second fan 400 and the first fan 300 are further reduced.

[0290] Moreover, the support section 513 is provided and may be beyond a side of the fastener 520 facing away from the second fan 400. In this way, the support section 513 and the air duct member fixing portion 227 can be connected, and the air duct member fixing portion 227 can support the output shaft 510 by supporting the support section 513, thus avoiding position interference of the output shaft fixing portion 512, the fastener 520 and the air duct member fixing portion 227. The free end of the output shaft 510 can be more easily mounted in the air duct member fixing portion 227, and the connection between the output shaft 510 and the air duct member fixing portion 227 is more stable and reliable.

[0291] In some embodiments of the present disclosure, as shown in FIG. 54 and FIG. 56, the air duct member fixing portion 227 is provided with a shaft sleeve fixing structure 228, a shaft sleeve 560 is mounted in the shaft sleeve fixing structure 228, and the output shaft 510 is arranged through the shaft sleeve 560.

[0292] The shaft sleeve fixing structure 228 may be configured as a fixing hole.

[0293] For example, the shaft sleeve 560 may be fixed within the shaft sleeve fixing structure 228 of the air duct member fixing portion 227. Since the output shaft 510 is arranged through the shaft sleeve 560 and rotates relative to the shaft sleeve 560, on the one hand, the output shaft 510 can be supported by using the shaft sleeve 560, so as to cause the vibration of the output shaft 510 during rotation to be smaller; on the other hand, a resistance of the output shaft 510 during rotation can be reduced, and rotational friction between the shaft sleeve 560 and the output shaft 510 may be smaller, so that abrasion of the output shaft 510 may be reduced and rotation of the output shaft 510 may be easier.

[0294] Further, as shown in FIG. 56, the shaft sleeve fixing structure 228 includes an accommodating section 2281 and a stopping section 2282.

[0295] The stopping section 2282 is arranged on a side of the accommodating section 2281 facing away from the output shaft 510. An inner diameter of the accommodating section 2281 is larger than that of the stopping section 2282, and the shaft sleeve 560 is mounted in the accommodating section 2281 and stopped at the stopping section 2282.

[0296] That is, the shaft sleeve 560 is mounted in the accommodating section 2281, and the stopping section 2282 may limit the shaft sleeve 560 in an axial direction. In this way, the shaft sleeve 560 can be closer to a side of the shaft sleeve fixing structure 228 facing the output shaft 510, so as to facilitate the output shaft 510 to be arranged through the shaft sleeve 560.

[0297] In addition, the output shaft 510 may pass through the shaft sleeve 560 and extend into the stopping section 2282, and the stopping section 2282 may avoid position interference between the output shaft 510 and a hole wall of the shaft sleeve fixing structure 228, so as to facilitate the rotation of the output shaft 510. Alternatively, the output shaft 510 may be inserted into the shaft sleeve 560 but not extend out of the shaft sleeve 560. That is, the output shaft 510 does not extend into the stopping section 2282. The arrangement of the stopping section 2282 can reduce a weight of the air duct member fixing portion 227, and the air duct member fixing portion 227 can be more easily fixed on the first air duct member 210 or the second air duct member 220 and is not prone to shake, so that the free end of the output shaft 510 can be supported by the air duct member fixing portion 227 and the shaft sleeve 560.

[0298] In some embodiments of the present disclosure, as shown in FIG. 58, the shaft sleeve 560 is provided with a shaft hole 562 and a plurality of vibration reduction portions 565. The output shaft 510 is arranged through the shaft hole 562, and the plurality of vibration reduction portions 565 are arranged at intervals along a circumferential direction of the shaft hole 562. The vibration reduction portion 565 may be configured as a vibration reduction hole.

[0299] Lubricating oil can be applied in the shaft hole 562 to facilitate relative rotation of the output shaft 510 and the shaft sleeve 560, and by providing the plurality of vibration reduction portions 565, not only a weight of the shaft sleeve 560 can be reduced, but also vibration transmission of the output shaft 510 can be reduced. That is, an amount of the vibration of the output shaft 510 transmitted to the air duct member fixing portion 227 through the shaft sleeve 560 can be smaller, and the shaft sleeve 560 can buffer the vibration of the output shaft 510, thereby further reducing the vibration and noise of the cabinet air conditioner and improving the use effect of the air conditioner.

[0300] In some embodiments of the present disclosure, as shown in FIG. 58, the shaft sleeve 560 includes an inner sleeve 561 and an outer sleeve 563.

[0301] The inner sleeve 561 is provided with the shaft hole 562, the outer sleeve 563 is arranged outside the inner sleeve 561, and the outer sleeve 563 and the inner sleeve 561 are connected by a plurality of connecting ribs 564. The outer sleeve 563, the inner sleeve 561 and adjacent connecting ribs 564 constitute the vibration reduction portion 565.

[0302] The plurality of connecting ribs 564 may be arranged at intervals along the circumferential direction of the shaft sleeve 560. That is, the plurality of vibration reduction portions 565 may be arranged at intervals along the circumferential direction of the shaft sleeve 560.

[0303] With this arrangement, the plural connecting ribs 564 may be respectively connected to the inner sleeve 561 and the outer sleeve 563, so that the vibration reduction portion 565 can be constructed between the adjacent connecting ribs 564, the vibration transmission of the output shaft 510 can be weakened by the shaft sleeve 560, connection strength of the inner sleeve 561 and the outer sleeve 563 can be ensured to be higher, overall structure strength of the shaft sleeve 560 is higher, and the shaft sleeve 560 is not easy to deform and damage.

[0304] As shown in FIG. 52 to FIG. 58, a cabinet air conditioner according to some embodiments of the present disclosure includes a body including a cabinet 100, a heat exchanger, a first air duct member 210, a second air duct member 220, a first fan 300, a second fan 400, and an electric motor 500.

[0305] The heat exchanger is arranged in an upper chamber, the first air duct member 210 is arranged in a lower chamber, a first air duct 201 is formed in the first air duct member 210, and outdoor air enters a room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the room or the outside through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver the indoor air to the room or the outside, and the second fan 400 is arranged in the first air duct 201 to deliver the outdoor air into the room. The electric motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are in transmission connection with the output shaft 510, and the electric motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously through the output shaft 510.

[0306] One of the first air duct member 210 and the second air duct member 220 is provided with a shaft sleeve 560, and an end of the output shaft 510 away from the electric motor 500 is rotatably arranged through the shaft sleeve 560.

[0307] For example, the electric motor 500 may be arranged in the first air duct member 210, and the output shaft 510 of the electric motor 500 extends towards the second air duct member 220. In this case, the shaft sleeve 560 may be arranged on the second air duct member 220, and the end of the output shaft 510 away from the electric motor 500 may be arranged through the shaft sleeve 560 on the second air duct member 220; alternatively, the electric motor 500 may be arranged in the second air duct member 220, and the output shaft 510 of the electric motor 500 extends towards the first air duct member 210. In this case, the shaft sleeve 560 may be arranged on the first air duct member 210, and the end of the output shaft 510 away from the electric motor 500 may be arranged through the shaft sleeve 560 on the first air duct member 210.

[0308] Thus, the end of the output shaft 510 away from the electric motor 500 may be rotatably connected with the shaft sleeve 560, and the shaft sleeve 560 may be configured to support a free end of the output shaft 510 without affecting the rotation of the output shaft 510, so that the electric motor 500 may drive the second fan 400 and the first fan 300 to rotate through the output shaft 510. After the shaft sleeve 560 supports the free end of the output shaft 510, the rotation of the output shaft 510 can be more stable. That is, vibration of the output shaft 510 during rotation can be smaller, and the output shaft 510 is not prone to shake, so that the vibration of the output shaft 510 and noise generated by the vibration can be greatly reduced, vibration and noise during operation of the cabinet air conditioner are smaller, and a use effect of the air conditioner is improved.

[0309] In the cabinet air conditioner according to some embodiments of the present disclosure, support of the output shaft 510 of the electric motor 500 can be enhanced, the rotation of the output shaft 510 is more stable, and the vibration and rotation noise are smaller, thereby improving the use effect of the air conditioner.

[0310] In some embodiments of the present disclosure, as shown in FIG. 53 to FIG. 55, one of the first air duct member 210 and the second air duct member 220 protrudes towards the output shaft 510 to form an air duct member fixing portion 227. The shaft sleeve 560 is mounted on the air duct member fixing portion 227, and the end of the output shaft 510 away from the electric motor 500 is rotatably arranged through the shaft sleeve 560.

[0311] By causing the air duct member fixing portion 227 to protrude from the first air duct member 210 or the second air duct member 220, the shaft sleeve 560 can be conveniently fixed by the air duct member fixing portion 227, the air duct member fixing portion 227 may be closer to the end of the output shaft 510 away from the electric motor 500, and after the shaft sleeve 560 is mounted to the air duct member fixing portion 227, the shaft sleeve may be closer to the end of the output shaft 510 away from electric motor 500, so that the end of the output shaft 510 away from the electric motor 500 can be conveniently inserted into the air duct member fixing portion 227, and assembly is more convenient.

[0312] Other constructions and operations of the cabinet air conditioner according to some embodiments of the present disclosure are known to those of ordinary skill in the art and will not be described in detail herein.

[0313] The cabinet air conditioner according to the present disclosure performs a cooling cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to air that is conditioned and subjected to heat exchange.

[0314] The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to an ambient environment through the condensation process.

[0315] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat exchange between evaporation latent heat of the refrigerant and a material to be cooled. The cabinet air conditioner can adjust a temperature and humidity of an indoor space throughout the cycle.

[0316] It will be understood by those skilled in the art that the scope of the disclosure of the present disclosure is not limited to the particular embodiments described above, and that modifications and substitutions of certain elements of the embodiments may be made without departing from the spirit of the disclosure. The scope of the present disclosure is limited by the appended claims.
