[0089] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0090] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0091] Reference below Figure 1-10 The figures describe cabinet air conditioners according to some embodiments of the present invention.

[0092] The cabinet air conditioner includes an indoor unit and an outdoor unit, which are connected by pipelines to transmit 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 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger respectively, so as to realize the cooling mode or heating mode of the cabinet air conditioner.

[0093] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0094] The outdoor heat exchanger is configured to perform heat exchange between outdoor air and the refrigerant transmitted 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 dissipates heat to the outdoor air through the outdoor heat exchanger and condenses. The outdoor heat exchanger works as an evaporator in the heating mode of the cabinet air conditioner, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

[0095] In some embodiments of the present invention, the outdoor heat exchanger further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0096] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet of the outdoor unit, and send the outdoor air after heat exchange with the outdoor heat exchanger out through the outdoor air outlet of the outdoor unit. The outdoor fan provides power for the flow of outdoor air.

[0097] The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger. The opening of the expansion valve adjusts the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger to adjust the flow of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The flow and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve can be an electronic valve, and the opening of the expansion valve is adjustable to control the flow and pressure of the refrigerant flowing through the expansion valve.

[0098] The four-way valve is connected to the refrigerant circuit, and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the cabinet air conditioner performs a cooling mode or a heating mode.

[0099] The indoor heat exchanger is configured to perform heat exchange between indoor air and the refrigerant transmitted 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 after heat dissipation through the outdoor heat exchanger absorbs the heat of the indoor air through the indoor heat exchanger and evaporates. The indoor heat exchanger works as a condenser in the heating mode of the cabinet air conditioner, so that the refrigerant after heat absorption through the outdoor heat exchanger dissipates the heat to the indoor air through the indoor heat exchanger and condenses.

[0100] In some embodiments of the present invention, the indoor heat exchanger further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0101] The indoor fan is configured to suck indoor air into the indoor unit through the third air inlet 110 of the indoor unit, and send the indoor air after heat exchange with the indoor heat exchanger out through the fourth air outlet 140 of the indoor unit. The indoor fan provides power for the flow of indoor air.

[0102] The cabinet air conditioner also includes a control device, which is mainly used to control the operating frequency of the compressor, the opening of the expansion valve, the speed of the outdoor fan and the speed of the indoor fan. The control device is connected to the compressor, the expansion valve, the outdoor fan and the indoor fan through a data line to transmit communication information.

[0103] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor, 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. The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a keyboard drive).

[0104] like Figure 1-Figure 10 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a ventilation component 200, and the ventilation component 200 can simultaneously draw fresh air into the room and exhaust indoor air.

[0105] like Figure 1-Figure 10As shown, the cabinet air conditioner can also include a housing 100 and a heat exchanger, wherein the housing 100 has an upper chamber and a lower chamber. Both the upper chamber and the lower chamber can be used for accommodating and installing, and other corresponding components in the cabinet air conditioner can be installed in the upper chamber and the lower chamber.

[0106] For example, the heat exchanger can be arranged in the upper chamber, so that the heat exchanger can be separated from the lower chamber. The heat exchanger plays a heat exchange role in the upper chamber and can heat the indoor air. The ventilation component 200 can be arranged in the lower chamber.

[0107] like Figure 1-Figure 5 As shown, the ventilation assembly 200 is used to deliver outdoor air to the room, and deliver indoor air to the outside. That is, the ventilation assembly 200 can discharge indoor dirty air to the outside while delivering outdoor fresh air to the room, so as to better achieve the renewal of indoor air.

[0108] The ventilation assembly 200 includes a first duct member 210, through which outdoor fresh air enters the room, a first air inlet 211 and a first air outlet 212 are formed on the first 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 also includes a second duct member 220, through which indoor air is discharged from the room, a second air inlet 221 and a second air outlet 222 are formed on the second duct member 220, and a second air duct 202 is formed between the second air inlet 221 and the second air outlet 222.

[0109] The first air duct 210 is a fresh air duct, the first air inlet 211 is a fresh air inlet, used to introduce outdoor fresh air into the first air duct 210, and the first air outlet 212 is a fresh air outlet, used to discharge outdoor fresh air from the first air duct 210 to be introduced into the room. The second air duct 220 is an exhaust air duct, the second air inlet 221 is an indoor air inlet, used to introduce indoor air into the second air duct 220, and the second air outlet 222 is an indoor air outlet, used to discharge turbid air in the room to the outside.

[0110] Among them, the first air duct member 210 is a structural member through which air flows. The first air duct member 210 is arranged in the lower chamber, so that the arrangement of the first air duct member 210 is more reasonable, which can avoid interference with the heat exchange of the upper chamber, and the first air duct member 210 can better play the role of air flow.

[0111] The first air inlet 211 mainly serves as an air intake, the first air outlet 212 mainly serves as an air outlet, and the first air duct 201 serves as a guide for air circulation. Specifically, outdoor fresh air enters the first air duct member 210 through the first air inlet 211, and then the fresh air enters the room through the first air outlet 212 along the first air duct 201, thereby achieving the introduction of outdoor fresh air.

[0112] Similarly, the second air duct member 220 is also a structural member for airflow to pass through. 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, which can avoid interference with the heat exchange of the upper chamber, and the second air duct member 220 can better play the role of airflow passing through.

[0113] The second air inlet 221 mainly serves as an air intake, the second air outlet 222 mainly serves as an air outlet, and the second air duct 202 serves as a guide for air circulation. Specifically, the dirty air in the room enters the second air duct member 220 through the second air inlet 221, and then the dirty air is discharged to the outside through the second air outlet 222 along the second air duct 202, thereby achieving the discharge of the dirty air in the room.

[0114] like Figure 5 As shown, the ventilation assembly 200 further includes a first fan 300, which is disposed in the second air duct 202 to deliver indoor air to the outdoors. This arrangement is more reasonable, and when the first fan 300 is working, the first fan 300 can firstly suck the indoor dirty air into the second air duct 202, and then discharge the indoor dirty air from the second air duct 202 to the outdoors, thereby achieving the discharge of indoor dirty air.

[0115] The first fan 300 may be an exhaust fan.

[0116] like Figure 5 As shown, the ventilation assembly 200 further includes a second fan 400, which is arranged in the first air duct 201 to deliver outdoor air to the room. This arrangement is more reasonable. When the second fan 400 is working, the second fan 400 can firstly suck the outdoor fresh air into the first air duct 201, and then release the outdoor fresh air from the first air duct 201 to the room, thereby achieving the introduction of outdoor fresh air.

[0117] The second fan 400 may be a fresh air fan.

[0118] like Figure 3 and Figure 6As shown, the ventilation assembly 200 further includes a motor 500 having a single output shaft 510, and the first fan 300 and the second fan 400 are drivingly connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate.

[0119] The motor 500 mainly plays a driving role. The motor 500 has a single output shaft 510, that is, the motor 500 outputs power to the outside only through the output shaft 510. The first fan 300 and the second fan 400 are transmission-connected to the output shaft 510. When the motor 500 is working, the motor 500 can simultaneously drive the first fan 300 and the second fan 400 to rotate through the output shaft 510, so that the first fan 300 can exhaust the dirty air in the room while the second fan 400 can inhale fresh air outside.

[0120] like Figure 3 As shown, the motor 500 is disposed 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 formed with an accommodation portion 310 to accommodate the motor 500. The other of the first fan 300 and the second fan 400 is formed with an avoidance portion 410 to avoid the accommodation portion 310, and the accommodation portion 310 is disposed corresponding to the avoidance portion 410.

[0121] like Figure 5 As shown, for example, if the first fan 300 is provided with a receiving portion 310, then the second fan 400 is provided with a avoiding portion 410, and the motor 500 can be arranged in the receiving portion 310 of the first fan 300, so that the motor 500 can be hidden inside the first fan 300. Moreover, the avoiding portion 410 can avoid the receiving portion 310, that is, the position of the receiving portion 310 can be arranged in the avoiding portion 410, so that the size of the avoiding portion 410 in the matching direction with the receiving portion 310 can be reduced, thereby reducing the volume of the ventilation component 200.

[0122] In addition, the avoidance portion 410 is arranged opposite to the accommodation portion 310, so that the size of the avoidance portion 410 in the relative direction to the accommodation portion 310 can be reduced, thereby reducing the volume of the ventilation component 200. The accommodation portion 310 can be a convex structure, and the avoidance portion 410 can be a concave structure.

[0123] In addition, one of the first fan 300 and the second fan 400 is provided with a first stop portion 320, and the other is provided with a second stop portion 420, and the first stop portion 320 and the second stop portion 420 cooperate with each other; when the motor 500 is working, the motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first stop portion 320 and the second stop portion 420 cooperate with each other to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0124] It should be noted that the first anti-rotation part 320 cooperates with the second anti-rotation part 420 to prevent the second fan 400 and the first fan 300 from rotating in the circumferential direction of the output shaft 510, that is, the second fan 400 and the first fan 300 will not rotate relative to each other, and the second fan 400 and the first fan 300 can rotate at the same frequency as the output shaft 510. At the same time, the first anti-rotation part 320 and the second anti-rotation part 420 cooperate to position the assembly of the second fan 400 and the first fan 300.

[0125] Therefore, even if the first fan 300 and the second fan 400 are subject to different wind resistances, after the first stop 320 and the second stop 420 cooperate, the fan with a faster speed can also drive the fan with a slower speed to rotate, and at the same time, the fan with a faster speed is affected by the fan with a slower speed and the speed of the fan decreases. For example, the wind resistance of the second fan 400 is larger and the wind resistance of the first fan 300 is smaller. At this time, the speed of the second fan 400 will be lower than the speed of the first fan 300. After the first stop 320 and the second stop 420 cooperate, the first fan 300 can drive the second fan 400 to rotate faster, and at the same time, the speed of the first fan 300 is affected by the second fan 400 and the speed is reduced, so that the first fan 300 and the second fan 400 can maintain a consistent speed, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the rotation noise and vibration of the first fan 300 and the second fan 400 during rotation, and providing a better user experience.

[0126] Therefore, by providing the accommodation portion 310 on one of the first fan 300 and the second fan 400, providing the avoidance portion 410 on the other, and providing the motor 500 in the first fan 300 or the second fan 400, while achieving the simultaneous exhaust and suction of air into the room, the volume occupied by the ventilation component 200 can be reduced, the cost can be reduced, and the versatility of the cabinet air conditioner can be improved.

[0127] In addition, the accommodation portion 310 is formed to protrude from the end surface of one of the first fan 300 and the second fan 400 along the axis of the first fan 300 toward the other of the first fan 300 and the second fan 400. That is, the structure of the accommodation portion 310 is configured to protrude toward the avoidance portion 410, and correspondingly, since the avoidance portion 410 is correspondingly arranged with the accommodation portion 310, the avoidance portion 410 is configured to be a recessed structure.

[0128] For example, the accommodating portion 310 is disposed on the first fan 300, the avoiding portion 410 is disposed on the second fan 400, and the accommodating portion 310 protrudes toward the second fan 400 along the axis of the first fan 300, so that the accommodating portion 310 and the avoiding portion 410 can be better adapted, so that the motor 500 can be installed in the accommodating portion 310. In this way, the extra space occupied by the motor 500 can be reduced, thereby reducing the overall volume of the ventilation assembly 200.

[0129] In some embodiments of the present invention, Figure 7 As shown, the receiving portion 310 includes: a first protrusion 311 and a second protrusion 312. The first protrusion 311 may have a cavity formed inside, and the second protrusion 312 mainly plays a connecting role.

[0130] like Figure 3 , Figure 7 and Figure 8 As shown, the first protrusion 311 protrudes toward the avoidance portion 410, so that the first protrusion 311 can be better adapted to the avoidance portion 410, thereby reducing the volume of the first protrusion 311 and the avoidance portion 410 after they are matched. The motor 500 is at least partially disposed in the first protrusion 311, that is, the motor 500 is at least partially hidden in the cavity formed inside the first protrusion 311, so that the motor 500 is easy to match with the first fan 300 or the second fan 400, and the extra space occupied by the motor 500 can be reduced, thereby reducing the overall volume of the ventilation component 200.

[0131] like Figure 3 and Figure 7 As shown, the second protrusion 312 protrudes toward the avoidance portion 410, and the second protrusion 312 is connected to the side of the first protrusion 311 adjacent to the avoidance portion 410, so that the second protrusion 312 can avoid interference with the arrangement of the motor 500, and at the same time can reduce the size of the avoidance portion 410 and the accommodating portion 310 in the relative direction. The motor 500 is transmission-connected to the second protrusion 312, so that the motor 500 can provide power for the second protrusion 312, that is, the motor 500 can drive the second protrusion 312 to rotate, thereby driving the first fan 300 or the second fan 400 to rotate, and then exhausting or sucking air can be achieved.

[0132] In some embodiments of the present invention, Figure 7 As shown, the cross-sectional area of ​​the first protrusion 311 gradually decreases in the direction toward the avoidance portion 410. In this way, the volume of the first protrusion 311 can be reduced while ensuring that the formed cavity is sufficient to cooperate with the motor 500, thereby reducing the manufacturing cost of the first protrusion 311. Moreover, the first protrusion 311 has an inclined surface structure, which can improve the structural strength of the accommodating portion 310 to a certain extent.

[0133] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, the avoidance portion 410 includes: a plurality of connecting strips 411 and a connecting plate 412. The plurality of connecting strips 411 extend in a direction away from the accommodating portion 310 and approach each other, the connecting plate 412 is respectively connected to the plurality of connecting strips 411, and the motor 500 is also in driving connection with the connecting plate 412.

[0134] The connecting strip 411 mainly plays a connecting role. The multiple connecting strips 411 extend in a direction away from the receiving portion 310 and are close to each other. In other words, the multiple connecting strips 411 are inclined structures that are close to the center. In this way, the inclined arrangement of the multiple connecting strips 411 corresponds to the structure of the receiving portion 310, and the receiving portion 310 can be arranged opposite to the avoidance portion 410. In addition, the multiple connecting strips 411 extend in a direction away from the receiving portion 310 and are close to each other. In this way, the receiving portion 310 can be matched between the multiple connecting strips 411, thereby forming a match between the avoidance portion 410 and the receiving portion 310, reducing the size of the avoidance portion 410 in the relative direction with the receiving portion 310, and further reducing the volume of the first fan 300 and the second fan 400 after matching.

[0135] The connecting plate 412 mainly plays a connecting role. The connecting plate 412 is connected to a plurality of connecting strips 411, so that the connecting plate 412 can be fixed, making the setting of the connecting plate 412 more reliable and stable. Because the motor 500 is also in transmission connection with the connecting plate 412, the motor 500 can drive the connecting plate 412 to rotate while driving the second protrusion 312 to rotate, that is, the motor 500 can simultaneously drive the accommodating portion 310 and the avoidance portion 410 to rotate, thereby simultaneously driving the first fan 300 and the second fan 400 to rotate, so as to achieve simultaneous indoor air suction and exhaust.

[0136] In some embodiments of the present invention, Figure 1-Figure 5 As shown, 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, wherein the first air duct shell 223 constitutes a first portion of the second air duct member 220, and the first air duct shell 223 constitutes a first portion of the first air duct member 210. The second air duct shell 224 constitutes a second portion of the second air duct member 220, and the third air duct shell 213 constitutes a second portion of the first air duct member 210.

[0137] The first air duct shell 223, the second air duct shell 224 and the third air duct shell 213 are all structural components through which air flows.

[0138] 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 can form a complete second air duct member 220, so that the indoor dirty air can be discharged in the second air duct member 220. Of course, the first fan 300 is arranged in the second air duct 202 in the second air duct member 220, so that the first fan 300 can suck the indoor dirty air from the second air inlet 221 into the second air duct member 220, and then discharge the indoor dirty air from the second air outlet 222 from the second air duct member 220 to the outside, thereby exhausting the indoor air.

[0139] 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 can form a complete first air duct member 210, so that outdoor fresh air can enter the first air duct member 210 through the first air inlet 211. Of course, the second fan 400 is arranged in the fresh air channel of the first air duct member 210, so that the second fan 400 can suck the outdoor fresh air from the first air inlet 211 into the first air duct member 210, and then release the outdoor fresh air from the first air duct member 210 to the room through the first air outlet 212, so as to release fresh air to the room.

[0140] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the first air duct shell 223 is provided with a limiting portion 2231, and the limiting portion 2231 can be configured as a convex shape, and the limiting portion 2231 is located between the accommodating portion 310 and the avoiding portion 410, and the limiting portion 2231 is provided to protrude toward the avoiding portion 410. The limiting portion 2231 is provided on the first air duct shell 223, so that a matching structure can be formed on the first air duct shell 223, so that the first air duct shell 223 can better match with the second air duct shell 224 and the third air duct shell 213.

[0141] Specifically, the limiting portion 2231 is located between the accommodating portion 310 and the avoiding portion 410, and the limiting portion 2231 is protruded toward the avoiding portion 410, that is, the limiting portion 2231 and the accommodating portion 310 have the same protruding direction. In this way, the accommodating portion 310 can be better matched with the limiting portion 2231, and the limiting portion 2231 can be better matched with the avoiding portion 410, so that the volume of the first air duct shell 223, the second air duct shell 224 and the third air duct shell 213 after matching can be reduced, and then the overall volume of the ventilation assembly 200 can be reduced.

[0142] Furthermore, if Figure 5 and Figure 6As shown, the cabinet air conditioner further includes a fastener 520. The motor 500 is provided with an output shaft 510, and an output shaft fixing portion 512 is provided at the end of the output shaft 510. For example, the output shaft fixing portion 512 can be a threaded section. The output shaft 510 passes through the first fan 300 and the second fan 400, and the fastener 520 is fixed to the output shaft fixing portion 512.

[0143] The fastener 520 mainly plays a fixing role, the output shaft 510 mainly plays a role in transmitting torque, and the output shaft fixing portion 512 mainly plays a fixing role. The output shaft 510 passes through the first fan 300 and the second fan 400, and the fastener 520 is fixed to the output shaft fixing portion 512, so that when the motor 500 drives the first fan 300 and the second fan 400 to rotate at the same time, the fastener 520 can be used to limit the first fan 300 and the second fan 400 in the axial direction of the output shaft 510, so that the first fan 300 and the second fan 400 can work more stably.

[0144] Specifically, Figure 5 and Figure 6 As shown, the fastener 520 is a nut, and the output shaft fixing portion 512 is a threaded section, and an external thread is provided on its surface, and the nut matches the external thread. This makes the assembly between the fastener 520 and the output shaft fixing portion 512 easier, and the connection between the nut and the external thread is relatively firm and stable, with high connection strength, and the structure of the nut and the external thread is simple, which is easy to process and set.

[0145] In addition, if Figure 6 , Fig. 9 and Fig.10 As shown, the cabinet air conditioner further includes: a motor bracket 530 and a motor pressing plate 540. The motor bracket 530 is fixed to the first air duct member 210 or the second air duct member 220, the motor pressing plate 540 is fixedly connected to the motor bracket 530, and the motor 500 is sandwiched between the motor bracket 530 and the motor pressing plate 540.

[0146] The motor bracket 530 mainly plays the role of installation, and the motor pressing plate 540 mainly plays the role of installation and limiting. The motor bracket 530 is fixed on the first air duct member 210 or the second air duct member 220, so that the motor bracket 530 can be fixed, making the setting of the motor bracket 530 more reliable and stable. The motor pressing plate 540 is fixedly connected to the motor bracket 530, so that the motor pressing plate 540 can be fixed, and the motor 500 is sandwiched between the motor bracket 530 and the motor pressing plate 540, so that the motor 500 can be limited and fixed by using the motor bracket 530 and the motor pressing plate 540, so that the motor 500 can work more stably.

[0147] In addition, if Fig. 9As shown, the motor bracket 530 is provided with a first mounting portion 531, the motor pressing plate 540 is provided with a second mounting portion 541, and the first mounting portion 531 is correspondingly mounted and connected with the second mounting portion 541. And / or the motor bracket 530 is provided with a first positioning portion 532, the motor pressing plate 540 is provided with a second positioning portion 542, and the first positioning portion 532 is correspondingly positioned and matched with the second positioning portion 542.

[0148] The first mounting portion 531 and the second mounting portion 541 can both play a role in installation, and the first mounting portion 531 and the second mounting portion 541 are correspondingly installed and connected, so that the first mounting portion 531 and the second mounting portion 541 can be used to connect the motor bracket 530 and the motor pressure plate 540 together, thereby making the connection between the motor bracket 530 and the motor pressure plate 540 more stable, so that the motor 500 can work better.

[0149] The first positioning portion 532 and the second positioning portion 542 can both play a positioning role, and the first positioning portion 532 and the second positioning portion 542 are positioned and matched, so that when the motor bracket 530 is matched with the motor pressing plate 540, the motor bracket 530 and the motor pressing plate 540 can be first positioned by the cooperation of the first positioning portion 532 and the second positioning portion 542. In this way, the assembly speed and assembly accuracy between the motor bracket 530 and the motor pressing plate 540 can be improved, and the assembly effect between the motor bracket 530 and the motor pressing plate 540 can be improved.

[0150] As another example, Figure 1-Figure 10 As shown, the first fan 300 and the second fan 400 are drivingly connected to the motor 500 .

[0151] The motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate. In addition, the motor 500 is disposed in one of the first fan 300 and the second fan 400.

[0152] In addition, one of the first fan 300 and the second fan 400 is formed with a receiving portion 310 to receive the motor 500.

[0153] The other of the first fan 300 and the second fan 400 is formed with an escape portion 410 to escape the accommodation portion 310. The accommodation portion 310 and the escape portion 410 are provided correspondingly.

[0154] Reference below Figure 11-Figure 21 The cabinet air conditioner according to some embodiments of the present invention is described.

[0155] Reference Figure 11-21As shown, the cabinet air conditioner of the embodiment of the utility model includes: a casing 100, a heat exchange fan, a first air duct member 210, a second air duct member 220, a motor 500, a first air duct 201, a second air duct 202, a purification air duct, a connecting port 230, a first baffle 240 and a second baffle 250, the first air duct member 210 can be a fresh air duct member, the second air duct member 220 is an exhaust air duct member, and the motor 500 can be a single-axis motor.

[0156] Among them, the interior of the casing 100 is formed with an upper chamber and a lower chamber located below the upper chamber, and the lower chamber is provided with a third air inlet 110 and a third air outlet 120. A second air duct 202 is defined from the third air inlet 110 to the third air outlet 120 in the cabinet air conditioner, wherein the third air inlet 110 is the indoor air inlet, and the third air outlet 120 is the indoor air outlet. The third air inlet 110 corresponds to the position of the second air inlet 221, so that the indoor air is introduced into the casing through the third air inlet 110 and introduced into the second air duct member 220 through the second air inlet 221, and the third air outlet 120 corresponds to the position of the second air outlet 222, so that the turbid air in the room is discharged to the outside through the second air outlet 222 and the third air outlet 120 in sequence.

[0157] In addition, a fifth air inlet 160 and a fifth air outlet 170 are provided on the lower chamber, and a first air duct 201 is defined from the fifth air inlet 160 to the fifth air outlet 170 in the cabinet air conditioner, wherein the fifth air inlet 160 is a fresh air inlet, and the fifth air outlet 170 is a fresh air outlet. The fifth air inlet 160 corresponds to the first air inlet 211 in position, so that outdoor fresh air is introduced into the casing through the fifth air inlet 160 and introduced into the first air duct member 220 through the first air inlet 211, and the fifth air outlet 170 corresponds to the first air outlet 212 in position, so that the outdoor fresh air is discharged to the outside through the first air outlet 212 and the fifth air outlet 170 in sequence.

[0158] In addition, a fourth air inlet 130 and a fourth air outlet 140 are also provided on the lower chamber, and a purified air duct is defined from the fourth air inlet 130 to the fourth air outlet 140 in the cabinet air conditioner, wherein the fourth air inlet 130 is the purified air inlet, and the fourth air outlet 140 is the purified air outlet, and the fourth air inlet 130 corresponds to the position of the second air inlet 221, so that the indoor air is introduced into the casing through the fourth air inlet 130 and introduced into the second air duct member 220 through the second air inlet 221, and the purified indoor air is discharged into the room again through the fourth air outlet 140.

[0159] Specifically, the cabinet air conditioner is divided into two parts, the upper part forms an upper chamber, and the lower part forms a lower chamber, and the upper chamber and the lower chamber are connected through the air supply duct 150. Indoor air can enter the cabinet air conditioner from the third air inlet 110 provided on the lower chamber, and be discharged 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 provided on the lower chamber, and be blown into the room from the fifth air outlet 170 after passing through the first air duct 201. In this way, indoor and outdoor air can be circulated, and the accumulation of harmful substances such as pollutants, bacteria, and viruses in the indoor air can be reduced, resulting in a decrease in indoor air quality, which is not conducive to the health of users.

[0160] In addition, a fourth air inlet 130 and a fourth air outlet 140 are also provided on the lower chamber. When the user turns on the indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet 130, and be discharged into the room from the fourth air outlet 140 after passing through the purification air duct. The indoor air can be filtered and purified to improve the indoor air quality. It should be noted that when the air circulation purification mode is turned on, the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202. At this time, the second air duct 202 is in an empty state.

[0161] In addition, the heat exchange fan is arranged in the upper chamber. When the cabinet air conditioner is running, the heat exchange fan drives the indoor air to enter the inside of the casing 100. The indoor air forms a heat exchange airflow after heat exchange with the heat exchanger. The heat exchange airflow is blown into the room under the drive of the heat exchange fan to adjust the indoor temperature.

[0162] Reference Figure 11-13 As shown, the cabinet air conditioner also includes a first duct member 210, which is arranged in the lower chamber. The first duct member 210 is used to draw outdoor air from the outside through the first duct 201 and blow it into the room through the first duct member 210; a fresh air cavity 214 is formed in the first duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0163] That is to say, the first duct member 210 is arranged in the lower chamber, and a fresh air chamber 214 is formed inside the first duct member 210. The second fan 400 is arranged in the fresh air chamber 214. When the second fan 400 is running, fresh air from the outside can be introduced from the fifth air inlet 160, and discharged through the fifth air outlet 170 on the first duct member 210. Driven by the heat exchange fan, the fresh air enters the upper chamber from the air supply duct 150, and forms a heat exchange airflow after heat exchange with the heat exchanger in the upper chamber. The heat exchange airflow is blown into the room driven by the heat exchange fan. Fresh air is introduced through the first duct member 210 and blown into the room, which can improve the indoor air quality, give users a closer to natural experience, and increase user comfort.

[0164] In addition, the cabinet air conditioner also includes a second duct member 220, which is arranged in the lower chamber and is spaced apart from the first duct member 210. The second duct member 220 is used to draw indoor air from the room and discharge it to the outside through the second air duct 202; an exhaust cavity 225 is formed in the second duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0165] That is to say, 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 is located on the side of the first air duct member 210 away from the third air outlet 120. A new 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 is running, it can introduce indoor air from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. In this way, the dirty air accumulated in the room can be discharged to the outside, thereby improving the indoor air quality.

[0166] In addition, the cabinet air conditioner further comprises a motor 500, the motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are connected to the output shaft 510, and when the motor 500 is running, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 can cooperate with the first air duct member 210 to inhale fresh outdoor air while discharging indoor dirty air, thereby maintaining good circulation of indoor air and improving indoor air quality.

[0167] Among them, the connecting port 230 is used to connect the first air duct 201 and the exhaust air duct. Since the indoor air enters the purification air duct when the indoor air circulation purification mode is turned on, the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and the second air duct 202 is in an empty state. In this way, when the connecting port 230 is not blocked, when the outdoor air enters the first air duct 201 from the fifth air inlet 160, it can also flow in the second air duct 202. Compared with the existing cabinet air conditioner, the cabinet air conditioner in the embodiment of the utility model makes full use of the existing components, and can effectively avoid the second air duct 202 from being idle without major changes. In addition, the channel for introducing 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, which can increase the amount of fresh air introduced and improve the indoor air quality.

[0168] In addition, the cabinet air conditioner also includes a first baffle 240 and a second baffle 250. The first baffle 240 can be rotatably disposed in the second air duct 202 or the first air duct 201 to open or close the connecting port 230; the second baffle 250 can be rotatably disposed in the second air duct 202 or the purification air duct to connect the third air inlet 110 and the third air outlet 120 and block the third air inlet 110 and the fourth air outlet 140.

[0169] That is, the first baffle 240 can rotate in the second air duct 202 or the first air duct 201, and the rotation angle can be clockwise or counterclockwise. The first baffle 240 can be used to open or close the connecting port 230 to control the connection between the first air duct 201 and the second air duct 202.

[0170] In addition, the second baffle 250 can rotate in the second air duct 202 or the purification air duct, and the rotation angle can be clockwise or counterclockwise. The second baffle 250 can be located at the purification air duct to block the airflow between the third air inlet 110 and the fourth air outlet 140, so that the third air inlet 110 and the third air outlet 120 are connected. At this time, the exhaust mode operates normally. The second baffle 250 can also be located at the second air duct 202 to block the airflow between the third air inlet 110 and the third air outlet 120, so that the third air inlet 110 and the fourth air outlet 140 are connected. At this time, the indoor air circulation purification mode is turned on.

[0171] Therefore, by setting the connecting port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the connecting port 230 can cooperate with each other to control the connection and disconnection of the first air duct 201 and the second air duct 202, and the second baffle 250 can control the switching between the exhaust mode and the indoor air circulation purification mode. When the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are connected through the connecting port 230, and the second air duct 202 is transformed into the first air duct 201, thereby increasing the fresh air volume of the cabinet air conditioner and improving the air quality of the living environment.

[0172] In some embodiments of the present invention, referring to Figure 12-13 As shown, the first baffle 240 has a first position and a second position; when the first baffle 240 is in the first position, the first baffle 240 blocks the connecting port 230; when the first baffle 240 is in the second position, the first baffle 240 opens the connecting port 230, so that the first air duct member 210 draws outdoor air from the outside through the first air duct 201 and the second air duct 202.

[0173] For example, when the first baffle 240 is located at the first position, the first baffle 240 can block the communication port 230. At this time, air cannot flow in the first air duct 201 and the second air duct 202. The second air duct 202 and the first air duct 201 respectively perform the functions of exhausting indoor polluted air and inhaling outdoor fresh air.

[0174] For another example, after the first baffle 240 is rotated clockwise, the first baffle 240 is located in the second position. At this time, the first baffle 240 does not block the connecting port 230, and air can flow 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. The first air duct 201 and the second air duct 202 introduce fresh air at the same time, which can increase the amount of fresh air, introduce more fresh air into the room, and improve the indoor air quality.

[0175] Furthermore, when the cabinet air conditioner is not in the indoor air circulation purification mode, the first baffle 240 can be rotated counterclockwise, and the first baffle 240 returns to the first position to block the connecting port 230. The second air duct 202 and the first air duct 201 each perform the function of discharging indoor polluted air and inhaling outdoor fresh air.

[0176] In some embodiments of the present invention, referring to Figure 12-13 As shown, when the first baffle 240 is located at the first position, the projection of the first baffle 240 on the horizontal plane covers the projection of the connecting port 230 on the horizontal plane. In other words, the area of ​​the first baffle 240 is larger than the area of ​​the connecting port 230, and the projection of the first baffle 240 on the horizontal plane can cover the projection of the connecting port 230 on the horizontal plane, so that the first baffle 240 can effectively block the connecting port 230 when it is located at the first position, so as to prevent the air from overflowing from the connecting 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 inhales the outdoor air, so that the indoor air is mixed, which is not conducive to improving the indoor air quality.

[0177] The horizontal plane may be a plane where the first baffle 240 is located at the communication opening 230 .

[0178] In some embodiments of the present invention, referring to Figure 12-13 As shown, the second baffle 250 has a third position and a fourth position; when the second baffle 250 is in the third position, the second baffle 250 disconnects the connection between the third air inlet 110 and the third air outlet 120 and connects the third air inlet 110 and the fourth air inlet 130; when the second baffle 250 is in the fourth position, the second baffle 250 disconnects the connection between the third air inlet 110 and the fourth air outlet 140 and connects the third air inlet 110 and the third air outlet 120.

[0179] For example, when the second baffle 250 is in the third position, the second baffle 250 can disconnect the third air inlet 110 and the third air outlet 120. Due to the blocking of the second baffle 250, the indoor air extracted by the second air duct member 220 cannot be discharged to the outside through the second air duct 202 and can only be transported to the indoor room. At this time, the cabinet air conditioner is in the indoor air circulation purification mode, and the second air duct 202 is in an idle state. At this time, the first baffle 240 can be in the second position, and the connecting port 230 connects the first air duct 201 and the second air duct 202. The first air duct member 210 can introduce outdoor fresh air from the first air duct 201 and the second air duct 202 at the same time, and the indoor fresh air volume is increased, which greatly improves the air quality of the indoor living environment.

[0180] For another example, when the second baffle 250 is in the fourth position, the second baffle 250 rotates counterclockwise from the third position, so that the third air inlet 110 is connected to the third air outlet 120. At this time, the first baffle 240 can be in the first position to shield the connecting port 230, and the second air duct 202 is separated from the first air duct 201. The air extracted from the room by the second air duct member 220 is discharged to the outside through the third air outlet 120 and the second air duct 202 in turn, and the dirty air accumulated in the room is discharged, which can maintain the circulation of the indoor air and improve the indoor air quality.

[0181] In some embodiments of the present invention, referring to Figure 14-15 As shown, the second baffle 250 and the first baffle 240 are an integrally formed structure and the junction is a pivoting portion 241 of the first baffle 240 and the second baffle 250, so that the first baffle 240 and the second baffle 250 rotate around the pivoting portion 241; the cabinet air conditioner also includes: a first driving member, and the first driving member and the pivoting portion 241 are in transmission cooperation. Specifically, a pivoting portion 241 is provided between the first baffle 240 and the second baffle 250, and the cabinet air conditioner is provided with a first driving member, and the first driving member and the pivoting portion 241 are in transmission cooperation, that is, the first driving member can drive the first baffle 240 and the second baffle 250 to rotate around the pivoting portion 241, and the first driving member can be a motor 500. In addition, the first baffle 240 and the second baffle 250 are an integrally formed structure, and the rotation range of the first baffle 240 and the second baffle 250 is degrees.

[0182] In this way, when the first baffle 240 is in the first position, the second baffle 250 is in the fourth position. At this time, the first baffle 240 covers the connecting port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 is connected to the third air outlet 120. At this time, the second air duct 202 is only used to cooperate with the second air duct member 220 to discharge indoor air and maintain the circulation of indoor air.

[0183] Furthermore, when the first baffle 240 is in the second position, the second baffle 250 is in the third position. At this time, the connecting port 230 between the second air duct 202 and the first air duct 201 is opened, and the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250. The indoor air extracted by the second air duct member 220 cannot be discharged through the second air duct 202, and is then output to the upper chamber, and is output to the indoor room after heat exchange in the heat exchanger, forming an indoor air circulation purification mode. Moreover, driven by the first air duct member 210, the second air duct 202 is connected to the first air duct 201 to jointly extract fresh air from the outdoors, thereby realizing the indoor air circulation purification mode while using the second air duct 202 to introduce fresh air, avoiding the second air duct 202 from being idle, and also increasing the amount of fresh air, keeping the indoor air fresh, and greatly improving the air quality of the indoor living environment.

[0184] In some embodiments of the present invention, referring to Fig.15 As shown, an escape 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, the projection of the escape space 251 on the horizontal plane covers the projection of the connecting port 230 on the horizontal plane, so that the escape space 251 is connected to the connecting port 230. Since the first baffle 240 and the second baffle 250 are an integrally formed structure, in order to prevent the connecting port 230 from being blocked when the first baffle 240 rotates to the second position and the second baffle 250 rotates to the third position, an escape 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, the projection of the escape space 251 on the horizontal plane covers the projection of the connecting port 230 on the horizontal plane.

[0185] That is to say, the area of ​​the avoidance space 251 is larger than the area of ​​the connecting port 230. When the first baffle 240 and the second baffle 250 rotate to the second position and the third position around the pivot portion 241, the first baffle 240 and the second baffle 250 will not block the connecting port 230, thereby ensuring smooth air circulation between the second air duct 202 and the first air duct 201 and introducing a large amount of fresh air.

[0186] Furthermore, the cabinet air conditioner further comprises: a second driving member, the second driving member is transmission-connected with the first baffle 240 to drive the first baffle 240 to rotate between the first position and the second position; and a third driving member, the third driving member is transmission-connected with the second baffle 250 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 can also be driven by different driving members, and the cabinet air conditioner further comprises a second driving member and a third driving member, the second driving member is transmission-connected with the first baffle 240, the third driving member is transmission-connected 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.

[0187] In this way, when the first baffle 240 is in the first position, the second baffle 250 can be in the third position. At this time, the connecting port 230 is shielded by the first baffle 240, and the third air inlet 110 and the third air outlet 120 are also separated by the second baffle 250. The air extracted from the room by the second duct member 220 can only be output to the upper chamber, and output to the room after heat exchange in the heat exchanger. The second duct member 220 only performs the indoor air circulation purification mode, and the second air duct 202 is in an idle state. When the first baffle 240 is in the first position, the second baffle 250 can also be in the fourth position. At this time, the first baffle 240 shields the connecting 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 connected. At this time, the second air duct 202 is only used to cooperate with the second duct member 220 to exhaust indoor air and maintain the circulation of indoor air.

[0188] Furthermore, when the first baffle 240 is in the second position, the second baffle 250 can be in the third position. At this time, the connecting port 230 between the second air duct 202 and the first air duct 201 is opened, and the third air inlet 110 and the third air outlet 120 are separated by the second baffle 250. The indoor air extracted by the second air duct member 220 cannot be discharged through the second air duct 202, and is then output to the upper chamber, and is output to the indoor after heat exchange in the heat exchanger, forming an indoor air circulation purification mode. Moreover, driven by the first air duct member 210, the second air duct 202 is connected to the first air duct 201 to jointly extract fresh air from the outdoors, thereby realizing the indoor air circulation purification mode while using the second air duct 202 to introduce fresh air, avoiding the second air duct 202 from being idle, and also increasing the amount of fresh air, keeping the indoor air fresh, and greatly improving the air quality of the indoor living environment.

[0189] However, when the first baffle 240 is in the second position, the second baffle 250 cannot be in the fourth position, otherwise, while the second air duct 202 is connected to the first air duct 201, the third air inlet 110 and the third air outlet 120 are also connected, so that the indoor dirty air is mixed with the outdoor fresh air, resulting in a reduction in indoor fresh air and a decrease in air quality, which is not conducive to the health of the user.

[0190] In some embodiments of the present invention, referring to Figure 12-13 and Fig.17 As shown, the second air duct member 220 is provided with a second air inlet 221, and the second air inlet 221 and the third air inlet 110 are arranged opposite to each other. In addition, the cabinet air conditioner further includes: an exhaust filter 226, which is fixed to the inner side of the housing 100 and sandwiched between the third air inlet 110 and the second air inlet 221. In which, the indoor air enters the second air duct 202 from the second air inlet 221 and the third air inlet 110 under the drive of the second air duct member 220. By sandwiching the exhaust filter 226 between the third air inlet 110 and the second air inlet 221, the indoor air inhaled by the second air duct member 220 can be filtered, and the air filtered by the exhaust filter 226 enters the room from the purification air duct to participate in the indoor air circulation, which can achieve purification of the indoor air and improve the air quality.

[0191] The exhaust filter unit 226 may be a filter.

[0192] In some embodiments of the present invention, referring to Fig.14 As shown, the cabinet air conditioner further includes: a fresh air filter 215, which is arranged in the first air duct 201 and opposite to the fifth air inlet 160. As the fresh air sucked from the outside by the operation of the second fan 400 can enter the first air duct 201 through the fifth air inlet 160, the fresh air filter 215 is arranged in the first air duct 201 and opposite to the fifth air inlet 160. After the air sucked from the outside is filtered by the fresh air filter 215, the cleanliness of the air blown out by the air conditioner can be improved, which is beneficial to the improvement of the living environment.

[0193] Among them, the fresh air filter unit 215 can be a filter.

[0194] And, if Fig.14 and Fig.16 As shown, the cabinet air conditioner also includes: an opening and closing member 161, which is rotatably arranged at the fifth air inlet 160, and the opening and closing member 161 has a fifth position and a sixth position. When the opening and closing member 161 is located at the fifth position, the opening and closing member 161 closes the fifth air inlet 160, and when the opening and closing member 161 is located at the sixth position, the opening and closing member 161 opens the fifth air inlet 160.

[0195] Specifically, the opening and closing member 161 is located at the fifth air inlet 160, and is used to control the opening and closing of the first air duct 201. When the first air duct member 210 stops running, when the opening and closing member 161 is located at the fifth position, the opening and closing member 161 closes the fifth air inlet 160, which can effectively prevent the outdoor wind from flowing back into the first air duct member 210 to generate noise, and provide a good quiet effect for the indoor space. When the opening and closing member 161 is located at the sixth position, the opening and closing member 161 opens the fifth air inlet 160, and the outdoor fresh air can enter the housing 100 from the fifth air inlet 160 to provide fresh air for the room. In addition, the opening and closing member 161 can be controlled by the motor 500.

[0196] Reference Figure 11-21 As shown, the cabinet air conditioner of some embodiments of the utility model includes: a casing 100, a heat exchange fan, a first air duct member 210, a second air duct member 220, a motor 500, a first air duct 201, a second air duct 202, a purification air duct, a connecting port 230, a first baffle 240 and a second baffle 250.

[0197] The housing 100 has an upper chamber and a lower chamber below the upper chamber, the lower chamber is provided with a third air inlet 110 and a third air outlet 120, the lower chamber is provided with a fifth air inlet 160 and a fifth air outlet 170, and the lower chamber is also provided with a fourth air inlet 130 and a fourth air outlet 140, and the heat exchange fan is arranged in the upper chamber. In addition, a first air duct 201 is defined between the fifth air inlet 160 and the fifth air outlet 170, a second air duct 202 is defined between the third air inlet 110 and the third air outlet 120, and a purification air duct is defined between the fourth air inlet 130 and the fourth air outlet 140.

[0198] Specifically, the cabinet air conditioner is divided into two parts, the upper part forms an upper chamber, and the lower part forms a lower chamber, and the upper chamber and the lower chamber are connected through the air supply duct 150. Indoor air can enter the cabinet air conditioner from the third air inlet 110 provided on the lower chamber, and be discharged 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 provided on the lower chamber, and be blown into the room from the fifth air outlet 170 after passing through the first air duct 201. In this way, indoor and outdoor air can be circulated, and the accumulation of harmful substances such as pollutants, bacteria, and viruses in the indoor air can be reduced, resulting in a decrease in indoor air quality, which is not conducive to the health of users.

[0199] In addition, a fourth air inlet and a fourth air outlet are also provided on the lower chamber. When the user turns on the indoor air circulation purification mode, the indoor air can enter the cabinet air conditioner through the fourth air inlet, and be discharged into the room from the fourth air outlet after passing through the purification air duct. The indoor air can be filtered and purified to improve the indoor air quality. It should be noted that when the air circulation purification mode is turned on, the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202. At this time, the second air duct 202 is in an empty state.

[0200] In addition, the heat exchange fan is arranged in the upper chamber. When the cabinet air conditioner is running, the heat exchange fan drives the indoor air to enter the inside of the casing 100. The indoor air forms a heat exchange airflow after heat exchange with the heat exchanger. The heat exchange airflow is blown into the room under the drive of the heat exchange fan to adjust the indoor temperature.

[0201] Reference Figure 12-13 As shown, the cabinet air conditioner also includes a first duct member 210, which is arranged in the lower chamber. The first duct member 210 is used to draw outdoor air from the outside through the first duct 201 and blow it into the room through the first duct member 210; a fresh air cavity 214 is formed in the first duct member 210, and a second fan 400 is arranged in the fresh air cavity 214.

[0202] That is to say, the first duct member 210 is arranged in the lower chamber, and a fresh air chamber 214 is formed inside the first duct member 210. The second fan 400 is arranged in the fresh air chamber 214. When the second fan 400 is running, fresh air from the outside can be introduced from the fifth air inlet 160, and discharged through the fifth air outlet 170 on the first duct member 210. Driven by the heat exchange fan, the fresh air enters the upper chamber from the air supply duct 150, and forms a heat exchange airflow after heat exchange with the heat exchanger in the upper chamber. The heat exchange airflow is blown into the room driven by the heat exchange fan. Fresh air is introduced through the first duct member 210 and blown into the room, which can improve the indoor air quality, give users a closer to natural experience, and increase user comfort.

[0203] In addition, the cabinet air conditioner also includes a second duct member 220, which is arranged in the lower chamber and is spaced apart from the first duct member 210. The second duct member 220 is used to draw indoor air from the room and discharge it to the outside through the second air duct 202; an exhaust cavity 225 is formed in the second duct member 220, and a first fan 300 is arranged in the exhaust cavity 225.

[0204] That is to say, 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 is located on the side of the first air duct member 210 away from the third air outlet 120. A new 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 is running, it can introduce indoor air from the third air inlet 110, pass through the second air duct 202, and then be discharged through the third air outlet 120. In this way, the dirty air accumulated in the room can be discharged to the outside, thereby improving the indoor air quality.

[0205] In addition, the cabinet air conditioner further comprises a motor 500, the motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are connected to the output shaft 510, and when the motor 500 is running, the first fan 300 and the second fan 400 are driven to rotate simultaneously. In this way, the motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second air duct member 220 can cooperate with the first air duct member 210 to inhale fresh outdoor air while discharging indoor dirty air, thereby maintaining good circulation of indoor air and improving indoor air quality.

[0206] Among them, the connecting port 230 is used to connect the first air duct 201 and the exhaust air duct. Since the indoor air enters the purification air duct when the indoor air circulation purification mode is turned on, the indoor air enters the purification air duct and cannot be discharged to the outside from the second air duct 202, and the second air duct 202 is in an empty state. In this way, when the connecting port 230 is not blocked, when the outdoor air enters the first air duct 201 from the fifth air inlet 160, it can also flow in the second air duct 202. Compared with the existing cabinet air conditioner, the cabinet air conditioner in the embodiment of the utility model makes full use of the existing components, and can effectively avoid the second air duct 202 from being idle without major changes. In addition, the channel for introducing 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, which can increase the amount of fresh air introduced and improve the indoor air quality.

[0207] In addition, the cabinet air conditioner also includes a first baffle 240 and a second baffle 250. The first baffle 240 can be rotatably disposed at the connecting port 230 to open or close the connecting port 230; the second baffle 250 can be rotatably disposed in the second air duct 202 or the purification air duct to connect the third air inlet 110 and the third air outlet 120 and block the third air inlet 110 and the fourth air outlet.

[0208] That is, the first baffle 240 can rotate at the communication port 230 , and the rotation angle can be clockwise or counterclockwise. The first baffle 240 can be used to open or close the communication port 230 to control the communication between the first air duct 201 and the second air duct 202 .

[0209] In addition, the second baffle 250 can rotate in the second air duct 202 or the purification air duct, and the rotation angle can be clockwise or counterclockwise. The second baffle 250 can be located at the purification air duct to block the airflow between the third air inlet 110 and the fourth air outlet, so that the third air inlet 110 and the third air outlet 120 are connected. At this time, the exhaust mode operates normally. The second baffle 250 can also be located at the second air duct 202 to block the airflow between the third air inlet 110 and the third air outlet 120, so that the third air inlet 110 and the fourth air outlet are connected. At this time, the indoor air circulation purification mode is turned on.

[0210] Therefore, by setting the connecting port 230, the first baffle 240 and the second baffle 250, the first baffle 240 and the connecting port 230 can cooperate with each other to control the connection and disconnection of the first air duct 201 and the second air duct 202, and the second baffle 250 can control the switching between the exhaust mode and the indoor air circulation purification mode. When the indoor air circulation purification mode is realized, the first air duct 201 and the second air duct 202 are connected through the connecting port 230, and the second air duct 202 is transformed into the first air duct 201, thereby increasing the fresh air volume of the cabinet air conditioner and improving the air quality of the living environment.

[0211] The cabinet air conditioner according to some embodiments of the present utility model is described below with reference to the accompanying drawings.

[0212] like Figure 22-Figure 29 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a casing 100 , a heat exchanger, a heat exchange fan and a ventilation assembly 200 .

[0214] 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 , a motor 500 , a filter portion, and a mounting bracket 600 .

[0215] The first air duct member 210 is arranged in the lower chamber, and a first air duct 201 is formed in the first air duct member 210. Outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, and a second air duct 202 is formed in the second air duct member 220. Indoor air is delivered to the indoor or outdoor through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver indoor air to the indoor or outdoor. The second fan 400 is arranged in the first air duct 201 to deliver outdoor air to the indoor. The motor 500 has a single output shaft 510. The first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate. The exhaust filter unit 226 is arranged on the air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0216] Among them, Figure 24-Figure 29 As shown, the mounting bracket 600 includes a bracket body 610, a motor mounting portion 620 and a filter mounting portion 630. The bracket body 610 is connected to the second air duct member 220, the motor mounting portion 620 is connected to the bracket body 610 and the motor mounting portion 620 extends into the second air duct member 220, the motor 500 is mounted on the motor mounting portion 620, the filter mounting portion 630 is connected to the bracket body 610, and the exhaust filter 226 is mounted on the filter mounting portion 630.

[0217] The exhaust filter 226 may be a filter. The motor 500 having a single output shaft 510 means that the motor 500 has only one output shaft 510, the output shaft 510 extends from one side of the motor 500, and the first fan 300 and the second fan 400 are connected to the output shaft 510 by transmission, and the first fan 300 and the second fan 400 are synchronously driven to rotate by the output shaft 510.

[0218] According to some embodiments of the cabinet air conditioner of the present invention, the casing 100 is provided with an upper chamber and a lower chamber, the heat exchanger is arranged in the upper chamber, the heat exchange fan is used to send the wind after heat exchange with the heat exchanger into the room, the ventilation component 200 is arranged in the lower chamber, and the ventilation component 200 is used to send outdoor air to the room, and send indoor air to the room or the outside. In this way, the ventilation component 200 can introduce outdoor air into the room through the first air duct 201, and then can purify the indoor air by outdoor fresh air, or, the ventilation component 200 can discharge the indoor air to the outside, so that the relatively dirty indoor air can be discharged to the outside, so as to quickly purify the indoor air after the outdoor air is introduced, or, the ventilation component 200 can suck the indoor air into the casing 100 and discharge it into the room after heat exchange with the heat exchanger, so that indoor cooling or heating can be quickly achieved.

[0219] Furthermore, the first air duct member 210 is disposed 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 disposed in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is sent to the room or the outside through the second air duct 202; the first fan 300 is disposed in the second air duct 202 to send indoor air to the room or the outside; the second fan 400 is disposed in the first air duct 201 to send outdoor air to the room. In this way, the first air duct member 210 can guide outdoor fresh air, and the second air duct member 220 can guide indoor air, so that the flow of outdoor fresh air and indoor air is separated, and interference between outdoor air and indoor air is avoided during flow, so that the air flow inside the cabinet air conditioner is smoother.

[0220] Moreover, the motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate. In this way, the first fan 300 and the second fan 400 can share one motor 500, which is beneficial to reducing the number of motors 500, making the number of parts of the cabinet air conditioner smaller, making assembly more convenient and reducing the space occupied by the motor 500, which is convenient for reducing the volume of the ventilation component 200. Moreover, the exhaust filter part 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter part 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving the air quality entering the interior of the cabinet air conditioner, which can not only improve the air outlet quality of the air conditioner, but also prevent dust and impurities from entering the casing 100.

[0221] In addition, the mounting bracket 600 includes a bracket body 610 , a motor mounting portion 620 and a filter mounting portion 630 , the motor 500 is mounted on the motor mounting portion 620 , the filter mounting portion 630 is connected to the bracket body 610 , and the exhaust filter portion 226 is mounted on the filter mounting portion 630 .

[0222] That is to say, the mounting bracket 600 of the embodiment of the utility model can be used to install the motor 500 and the exhaust filter unit 226 at the same time, that is, the motor 500 and the exhaust filter unit 226 can be installed on one bracket, which can reduce the number of brackets, make the mounting bracket 600 more integrated, and make assembly more convenient and quick, which is conducive to improving assembly efficiency.

[0223] Moreover, it can be understood that, compared with the prior art in which two brackets are provided to respectively fix the motor 500 and the exhaust filter part 226, the cabinet air conditioner of the embodiment of the utility model can reduce one bracket, thereby saving a set of molds for producing the bracket, which is beneficial to reducing the production cost of the installation bracket 600.

[0224] In addition, by connecting the bracket body 610 and the second air duct member 220, the motor mounting portion 620 is connected to the bracket body 610 and the motor mounting portion 620 extends into the second air duct member 220, and the filter mounting portion 630 can be located outside the second air duct member 220. As a result, the motor 500 can extend into the second air duct member 220 after being installed on the motor mounting portion 620, and the motor 500 can be closer to the first fan 300 and the second fan 400, so that the output shaft 510 of the motor 500 can be respectively connected to the first fan 300 and the second fan 400. In addition, the exhaust filter portion 226 can be located outside the second air duct member 220 after being installed on 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, thereby more effectively preventing dust and impurities from entering the second air duct member 220 to keep the interior of the second air duct member 220 clean, thereby improving the air outlet quality of the cabinet air conditioner.

[0225] In this way, the cabinet air conditioner according to some embodiments of the present invention can use the mounting bracket 600 to simultaneously fix the motor 500 and the exhaust filter 226, which has the advantages of high integration, convenient assembly and cost saving.

[0226] In some embodiments of the present invention, Fig.25 , Fig. 27 and Fig.28 As shown, the filter mounting portion 630 includes a frame 631 and a buckle 632 .

[0227] The frame 631 is connected to the side of the bracket body 610 facing away from the motor mounting portion 620, and the frame 631 and the bracket body 610 together form a storage space for accommodating the exhaust filter portion 226. The buckle 632 is connected to the frame 631. The buckle 632 is located on the side of the exhaust filter portion 226 facing away from the bracket body 610, and is used to stop the exhaust filter portion 226.

[0228] For example, the frame 631 may be constructed into a circular, rectangular, polygonal or other shape, and may be specifically configured according to the shape of the exhaust filter 226 so that the frame 631 may surround the exhaust filter 226 .

[0229] Among them, the exhaust filter part 226 can be parallel to the bracket body 610, and the bracket body 610 can be used to separate the motor mounting part 620 and the filter mounting part 630, that is, the motor mounting part 620 and the exhaust filter part 226 mounting part can be respectively located on the opposite sides of the thickness direction of the bracket body 610, so that the motor 500 and the exhaust filter part 226 can be respectively located on the opposite sides of the thickness direction of the bracket body 610, so that the bracket body 610 can be used to separate the motor 500 and the exhaust filter part 226 to avoid position interference between the motor 500 and the exhaust filter part 226, and the structural setting is more reasonable.

[0230] In addition, the frame 631 can extend along the circumference of the exhaust filter part 226, and then the frame 631 can be used to block the edge of the exhaust filter part 226, which is beneficial to improve the protection effect of the exhaust filter part 226, and the buckle 632 and the bracket body 610 can respectively stop at the opposite sides of the thickness direction of the exhaust filter part 226. The bracket body 610 can prevent the exhaust filter part 226 from excessively extending into the mounting bracket 600, and the buckle 632 can prevent the exhaust filter part 226 from detaching from the mounting bracket 600, so that the connection between the exhaust filter part 226 and the mounting bracket 600 is more stable and reliable.

[0231] In addition, it should be noted that the buckle 632 can be set to be multiple, and the multiple buckles 632 are distributed at intervals along the circumference of the frame 631, and then the multiple buckles 632 can be stopped at multiple circumferential positions of the exhaust filter part 226, thereby further improving the connection reliability between the exhaust filter part 226 and the mounting bracket 600, preventing the exhaust filter part 226 from detaching from the mounting bracket 600, and the exhaust filter part 226 can more stably cover the air inlet side of the second air duct member 220.

[0232] In some embodiments of the present invention, Fig.28 As shown, a flange 633 is formed on the side of the frame 631 facing away from the bracket body 610 , and the flange 633 is bent in a direction away from the exhaust filter portion 226 .

[0233] By providing the flange 633, the structural strength of the frame 631 can be improved, and the frame 631 is not easily deformed, so that the connection strength between the frame 631 and the exhaust filter part 226 is higher, and the frame 631 can more reliably fix the exhaust filter part 226. In addition, by bending the flange 633 away from the exhaust filter part 226, the flange 633 will not interfere with the exhaust filter part 226, thereby facilitating the assembly of the exhaust filter part 226 and the mounting bracket 600.

[0234] In some embodiments of the present invention, Fig. 27 and Fig.28 As shown, one side of the 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 motor mounting portion 620 and the buckle 632 .

[0235] Specifically, the side of the motor mounting portion 620 facing the exhaust filter portion 226 protrudes out from the side of the bracket body 610 facing the exhaust filter portion 226, so that the motor mounting portion 620 and the buckle 632 can respectively stop the opposite sides of the thickness direction of the exhaust filter portion 226, so as to make the positioning of the exhaust filter portion 226 more stable and prevent the exhaust filter portion 226 from moving.

[0236] Moreover, it can be understood that the motor 500 and the exhaust filter part 226 are respectively located on opposite sides of the bracket body 610. By protruding the side of the motor mounting part 620 facing the exhaust filter part 226 out of the bracket body 610, the exhaust filter part 226 can be spaced apart from the bracket body 610 after stopping at the motor mounting part 620, thereby making the exhaust filter part 226 and the motor 500 farther apart, further avoiding position interference between the exhaust filter part 226 and the fan.

[0237] In some embodiments of the present invention, Fig.26 and Fig.29 As shown, the motor mounting portion 620 includes a base 621 and a plurality of fixing columns 622 .

[0238] The base 621 is used to support one axial end of the motor 500 , one end of each fixing column 622 is respectively connected to the base 621 and the bracket body 610 , and multiple fixing columns 622 are arranged along the circumference of the motor 500 , and the motor 500 is installed between the multiple fixing columns 622 .

[0239] For example, the cross-sectional area of ​​the end of the fixing column 622 facing the bracket body 610 may be larger, so that the end of the fixing column 622 facing the bracket body 610 can be connected and fixed to the base 621 and the bracket body 610 respectively.

[0240] After the motor 500 is mounted on the motor mounting portion 620, a stop plate may be connected to one end of the fixing column 622 facing away from the base 621, and the stop plate may be stopped at the end of the motor 500 facing away from the base 621, and a through hole may be provided in the center of the stop plate to facilitate the output shaft 510 to pass through the stop plate. The stop plate may be the same component as the motor pressure plate 540 in the above embodiment.

[0241] In addition, there can be no less than three fixing columns 622, so that multiple fixing columns 622 can radially position the motor 500 to prevent the motor 500 from radially offset relative to the motor mounting portion 620, and the base 621 and the stop plate can be stopped at the axial ends of the motor 500 respectively to fix the motor 500 in the axial direction of the motor 500 to prevent the motor 500 from axially offset.

[0242] In some embodiments of the present invention, Fig.24 , Figure 26-Figure 29 As shown, at least one of the bracket body 610 and the motor mounting portion 620 is configured with a first wire passing portion 611, and the filter mounting portion 630 is configured with a second wire passing portion 634, and the wire harness 550 of the motor 500 passes through the first wire passing portion 611 and the second wire passing portion 634 in sequence.

[0243] 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.

[0244] Specifically, the first wire-passing portion 611 can pass through the bracket body 610 along the axial direction of the mounting bracket 600, and the second wire-passing portion 634 can pass through the frame 631 of the filter mounting portion 630 along the radial direction of the mounting bracket 600. Thus, the wiring harness 550 of the motor 500 can first pass through the first wire-passing portion 611, so that the wiring harness 550 can pass from the side of the bracket body 610 facing the motor 500 to the other side of the bracket body 610, and then the wiring harness 550 passes through the second wire-passing portion 634, that is, the wiring harness 550 can extend to the outside of the mounting bracket 600 to facilitate electrical connection between the wiring harness 550 and the power supply. Moreover, after the wiring harness 550 passes through the first wire-passing portion 611 and the second wire-passing portion 634, the mounting bracket 600 can also constrain the wiring harness 550 to make the routing of the wiring harness 550 in the ventilation component 200 more regular and convenient for layout.

[0245] In some embodiments of the present invention, Figure 26-Figure 29 As shown, the bracket body 610 is configured with a grille 612, the grille 612 avoids the motor mounting portion 620, and the grille 612 is formed with a hollow portion 613, and at least one of the plurality of hollow portions 613 is configured as a first wire passing portion 611. The hollow portion 613 can be configured as a grille hole.

[0246] It can be understood that the hollow portion 613 is usually set to be smaller. In order to facilitate the passage of the wiring harness 550 of the motor 500, two or more adjacent hollow portions 613 can be connected to form a first wire-passing portion 611, so that the aperture of the first wire-passing portion 611 can be larger, and the wiring harness 550 of the motor 500 can more easily pass through the first wire-passing portion 611, and assembly is more convenient.

[0247] In some embodiments of the present invention, Fig. 27 and Fig.28 As shown, a limiting rib 614 is provided on the bracket body 610, 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 can be located between the first wire passing portion 611 and the second wire passing portion 634, so that 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 constrain the wire harness 550.

[0248] Specifically, the limiting ribs 614 can be multiple, for example, two limiting ribs 614 can be set, 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 motor mounting portion 620, so that the limiting rib 614 and the motor mounting portion 620 can be used to limit the wire harness 550 to prevent the wire harness 550 from deviating in the radial direction of the mounting bracket 600. In addition, the other limiting rib 614 can be connected to the motor mounting portion 620. The side facing the exhaust filter portion 226, and the limiting rib 614 can extend in a direction perpendicular to the axial direction of the mounting bracket 600, so that the bracket can be used to stop the side of the wiring harness 550 that is away from the mounting bracket 600, that is, the bracket body 610, the motor mounting portion 620 and the above-mentioned two limiting ribs 614 can be used to limit multiple directions of the wiring harness 550 to avoid positional displacement of the wiring harness 550, thereby avoiding positional interference between the wiring harness 550 and other components in the ventilation assembly 200, which is convenient for layout.

[0249] like Figure 22-Figure 29 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a casing 100 , a heat exchanger, a heat exchange fan and a ventilation assembly 200 .

[0250] The casing 100 has an upper chamber and a lower chamber. The heat exchanger is arranged in the upper chamber. The heat exchange fan is used to send the air after heat exchange with the heat exchanger into the room. The ventilation component 200 is arranged in the lower chamber. The ventilation component 200 is used to send outdoor air to the room, and send indoor air to the room or the outside.

[0251] 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 , a motor 500 , an exhaust filter 226 and a mounting bracket 600 .

[0252] The first air duct member 210 is arranged in the lower chamber, and a first air duct 201 is formed in the first air duct member 210. Outdoor fresh air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, and a second air duct 202 is formed in the second air duct member 220. Indoor air is delivered to the indoor or outdoor through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver indoor air to the indoor or outdoor. The second fan 400 is arranged in the first air duct 201 to deliver outdoor air to the indoor. The motor 500 has a single output shaft 510. The first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate. The exhaust filter unit 226 is arranged on the air inlet side of the second air duct 202 to purify the indoor air entering the second air duct 202.

[0253] The mounting bracket 600 is connected to the second air duct member 220 , and the motor 500 and the exhaust filter unit 226 are both mounted on the mounting bracket 600 .

[0254] Therefore, by setting the casing 100 with an upper chamber and a lower chamber, the heat exchanger is arranged in the upper chamber, the heat exchange fan is used to send the air after heat exchange with the heat exchanger into the room, and the ventilation component 200 is arranged in the lower chamber. The ventilation component 200 is used to send outdoor air to the room, and send indoor air to the room or the outside. In this way, the ventilation component 200 can introduce outdoor air into the room through the first air duct 201, and then purify the indoor air with outdoor fresh air. Alternatively, the ventilation component 200 can discharge the indoor air to the outside, so that the relatively dirty indoor air can be discharged to the outside, so as to quickly purify the indoor air after introducing outdoor air. Alternatively, the ventilation component 200 can suck the indoor air into the casing 100, exchange heat with the heat exchanger, and then discharge it into the room, so as to quickly achieve indoor cooling or heating.

[0255] Furthermore, the first air duct member 210 is disposed 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 disposed in the lower chamber, a second air duct 202 is formed in the second air duct member 220, and indoor air is sent to the room or the outside through the second air duct 202; the first fan 300 is disposed in the second air duct 202 to send indoor air to the room or the outside; the second fan 400 is disposed in the first air duct 201 to send outdoor air to the room. In this way, the first air duct member 210 can guide outdoor fresh air, and the second air duct member 220 can guide indoor air, so that the flow of outdoor fresh air and indoor air is separated, and interference between outdoor air and indoor air is avoided during flow, so that the air flow inside the cabinet air conditioner is smoother.

[0256] Moreover, the motor 500 has an output shaft 510, and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate, so that the first fan 300 and the second fan 400 can share one motor 500, which is beneficial to reducing the number of motors 500, making the number of parts of the cabinet air conditioner smaller, making assembly more convenient and reducing the space occupied by the motor 500, which is convenient to reduce the volume of the ventilation component 200, and the exhaust filter part 226 is arranged on the air inlet side of the second air duct 202, so that the exhaust filter part 226 can be used to purify the indoor air entering the second air duct 202, which is beneficial to improving the air quality entering the interior of the cabinet air conditioner, which can not only improve the air outlet quality of the air conditioner, but also prevent dust and impurities from entering the casing 100.

[0257] In addition, the mounting bracket 600 can be used to simultaneously mount the motor 500 and the exhaust filter unit 226, that is, the motor 500 and the exhaust filter unit 226 can be mounted on one bracket, which can reduce the number of brackets, making the mounting bracket 600 more integrated and assembling more convenient and quick, thereby helping to improve assembly efficiency.

[0258] Moreover, it can be understood that, compared with the prior art in which two brackets are provided to respectively fix the motor 500 and the exhaust filter part 226, the cabinet air conditioner of the embodiment of the utility model can reduce one bracket, thereby saving a set of molds for producing the bracket, which is beneficial to reducing the production cost of the installation bracket 600.

[0259] According to some embodiments of the present invention, the cabinet air conditioner can use the mounting bracket 600 to fix the motor 500 and the exhaust filter 226 at the same time, which has the advantages of high integration, convenient assembly and cost saving.

[0260] In some embodiments of the present invention, Fig.24 , Figure 26-Figure 29 As shown, the mounting bracket 600 is provided with a first wire passing portion 611 and a second wire passing portion 634 , the second wire passing portion 634 is located at the edge of the mounting bracket 600 , and the wiring harness 550 of the motor 500 passes through the first wire passing portion 611 and the second wire passing portion 634 in sequence.

[0261] In this way, the wire harness 550 can pass through the mounting bracket 600 through the second wire passing portion 634 to facilitate the electrical connection between the wire harness 550 and the power supply, so that the motor 500 can be electrically connected to the power supply. In addition, the mounting bracket 600 can also fix the wire harness 550 through the first wire passing portion 611 and the second wire passing portion 634 to make the routing of the wire harness 550 in the ventilation component 200 more regular and facilitate layout.

[0262] The cabinet air conditioner according to some embodiments of the present utility model is described below with reference to the accompanying drawings.

[0263] like Figure 30-Figure 39 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a main body, a switching assembly 700 and a fresh air inlet pipe 730, and the main body includes a casing 100, a heat exchanger and a fresh air fan.

[0264] The main body includes an upper chamber and a lower chamber located below the upper chamber, a fifth air inlet 160 is formed on the casing 100, the heat exchanger is arranged in the upper chamber, and the fresh air fan is arranged in the lower chamber. The fresh air fan drives the outdoor air into the lower chamber through the fifth air inlet 160, one end of the adapter component 700 is connected to the fifth air inlet 160, and the other end of the adapter component 700 is connected to the fresh air inlet pipe 730, and the adapter component 700 connects the fresh air inlet pipe 730 and the fifth air inlet 160.

[0265] The adapter assembly 700 includes a first adapter 710 and a second adapter 720. One end of the first adapter 710 is connected to the housing 100 and communicates with the fifth air inlet 160. Both ends of the second adapter 720 are respectively connected to the other end of the first adapter 710 and the fresh air inlet pipe 730. The second adapter 720 is rotatable relative to the first adapter 710 to adjust the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720.

[0266] The first adapter 710 can be plugged or connected to the housing 100 by bolts. For example, the first adapter 710 can be configured with a mounting ear 716, the housing 100 can be configured with a bolt hole, and the mounting ear 716 of the first adapter 710 can be connected to the housing 100 by bolts. The second adapter 720 and the fresh air inlet pipe 730 can be plugged and connected. For example, the second adapter 720 can be inserted into the fresh air inlet pipe 730 and have an interference fit with the fresh air inlet pipe 730.

[0267] The second adapter 720 being rotatable relative to the first adapter 710 means that the second adapter 720 can rotate relative to the first adapter 710 along its central axis, or in other words, the first adapter 710 can rotate relative to the second adapter 720 along its central axis.

[0268] According to some embodiments of the cabinet air conditioner of the present invention, the heat exchanger is arranged in the upper chamber, the fresh air fan is arranged in the lower chamber, the fresh air fan drives the outdoor air to enter the lower chamber through the fifth air inlet 160, one end of the adapter component 700 is connected with the fifth air inlet 160, and the other end of the adapter component 700 is connected with the fresh air inlet pipe 730, and the adapter component 700 connects the fresh air inlet pipe 730 and the fifth air inlet 160. In this way, the outdoor air can be guided to the fifth air inlet 160 through the fresh air inlet pipe 730, and flow into the room through the fifth air inlet 160 to purify the indoor air.

[0269] In addition, the adapter assembly 700 includes a first adapter 710 and a second adapter 720, one end of the first adapter 710 is connected to the housing 100 and communicates with the fifth air inlet 160, and both ends of the second adapter 720 are respectively connected to 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 the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720.

[0270] In this way, the angle between the first adapter 710 and the second adapter 720 can be adjusted according to the installation position of the cabinet air conditioner, that is, by rotating the first adapter 710 and the second adapter 720 relative to each other, the angle between the central axis of the fresh air inlet pipe 730 and the central axis of the fifth air inlet 160 can be adjusted.

[0271] For example, Fig.30 As shown, when the fifth air inlet 160 is facing the wall 740, the first adapter 710 and the second adapter 720 can be rotated relative to each other so that the central axis of the first adapter 710 and the central axis of the second adapter 720 coincide, that is, the adapter assembly 700 is in a straight line, so that it is convenient for the fresh air inlet pipe 730 to pass through the wall 740 and then be connected to the fifth air inlet 160 through the adapter assembly 700, which is beneficial to reducing the space occupied by the adapter assembly 700. Moreover, the adapter assembly 700 has no bends, and the airflow resistance in the adapter assembly 700 is smaller. The outdoor air can flow more smoothly through the fresh air inlet pipe 730 and the adapter assembly 700 to the fifth air inlet 160, thereby facilitating the introduction of outdoor fresh air into the room.

[0272] When the fifth air inlet 160 is inclined relative to the wall 740, for example, Fig.38 As shown, when the fifth air inlet 160 is facing the corner of the wall 740, that is, when the fresh air inlet pipe 730 is inclined relative to the central axis of the fifth air inlet 160, the first adapter 710 and the second adapter 720 can be rotated relative to each other to make the adapter assembly 700 bent, so that the central axis of the first adapter 710 can coincide with the central axis of the fifth air inlet 160, so that the first adapter 710 and the casing 100 are connected and communicated with the fifth air inlet 160, and the central axis of the second adapter 720 can coincide with the central axis of the fresh air inlet pipe 730, so that the second adapter 720 and the fresh air inlet pipe 730 are connected. The installation is more convenient and quick, and the space occupied by the adapter assembly 700 can be smaller, which is beneficial to reducing the space required for the installation of the cabinet air conditioner.

[0273] Therefore, when the cabinet air conditioner is installed in different positions and the fifth air inlet 160 is facing the wall 740 or inclined relative to the wall 740, the adapter assembly 700 can be adjusted according to the installation position of the cabinet air conditioner to change the angle between the first adapter 710 and the second adapter 720, so that the adapter assembly 700 can adapt to installation at multiple angles, and the connection between the fresh air inlet pipe 730, the adapter assembly 700 and the casing 100 is more convenient, and it can save the installation space of the cabinet air conditioner and facilitate installation.

[0274] In this way, the cabinet air conditioner according to some embodiments of the present invention can meet the requirements of different installation environments, and has the advantages of high installation efficiency, convenient installation and small installation space.

[0275] In some embodiments of the present invention, Fig.34 As shown, one of the first adapter 710 and the second adapter 720 is configured with a second clamping structure 721 , and the other is configured with a first clamping structure 711 , and the second clamping structure 721 is rotatably clamped in the first clamping structure 711 .

[0276] The first clamping structure 711 may be a clamping ring groove, and the second clamping structure 721 may be a clamping ring platform.

[0277] For example, the end of the first adapter 710 facing the second adapter 720 can be constructed with a first clip-on structure 711, and the end of the second adapter 720 facing the first adapter 710 can be constructed with a second clip-on structure 721. The first clip-on structure 711 and the second clip-on structure 721 are clipped to each other, which not only makes the connection structure simple and easy to connect the first adapter 710 and the second adapter 720, but also the second clip-on structure 721 can rotate within the first clip-on structure 711, thereby enabling the first adapter 710 and the second adapter 720 to rotate relative to each other, and the first adapter 710 and the second adapter 720 are not easily separated during the relative rotation.

[0278] Furthermore, if Figure 32-Figure 37 As shown, the outer contour of the second clamping structure 721 and the inner contour of the first clamping structure 711 are configured as matching circles.

[0279] Therefore, no matter to which angle the second clamping structure 721 is rotated relative to the first clamping structure 711, the outer circumference of the second clamping structure 721 and the inner circumference of the first clamping structure 711 can fit together, so that the second clamping structure 721 can be stably clamped in the first clamping structure 711, and rotational interference between the inner circumference of the first clamping structure 711 and the second clamping structure 721 can be avoided, so that the relative rotation of the first adapter 710 and the second adapter 720 is easier.

[0280] In some embodiments of the present invention, Fig.36 and Fig.37 As shown, the central axis of the second clamping structure 721 forms a first inclination angle with the central axis of one of the first adapter 710 and the second adapter 720, and the central axis of the first clamping structure 711 forms a second inclination angle with the central axis of the other of the first adapter 710 and the second adapter 720. The difference between the first inclination angle and the second inclination angle is A, and A satisfies: -10°≤A≤10°.

[0281] For example, the first clamping structure 711 may be provided on the first adapter 710, and the second clamping structure 721 may be provided on the second adapter 720. Fig.36 As shown, the angle between the central axis of the first adapter 710 and the central axis of the first clamping structure 711 is B, that is, the second inclination angle is B; Fig.37 As shown, the angle between the central axis of the second adapter 720 and the central axis of the second clamping structure 721 is C, that is, the first inclination angle is C.

[0282] Among them, the first inclination angle can be equal to the second inclination angle. In this way, by allowing the first adapter 710 and the second adapter 720 to rotate relative to each other, 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 the extreme position, the adapter assembly 700 can be linear, so that when the fresh air inlet duct 730 and the fifth air inlet 160 are facing each other, the fresh air inlet duct 730 and the fifth air inlet 160 can be connected through the adapter assembly 700.

[0283] Of course, there may be a certain 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°.

[0284] In this way, there can be an extrusion pressure between the second clip-on structure 721 and the first clip-on structure 711, which is beneficial to improving the sealing between the second clip-on structure 721 and the first clip-on structure 711, and the difference between the first inclination angle and the second inclination angle will not be too large, so as to avoid the bending angle between the first adapter 710 and the second adapter 720 being too small during the relative rotation of the first adapter 710 and the second adapter 720, thereby ensuring that the airflow resistance in the adapter assembly 700 is small and the flow of outdoor air in the adapter assembly 700 is smoother.

[0285] In addition, it can be understood that when the first adapter 710 and the second adapter 720 rotate relative to each other, the second clip structure 721 and the first clip structure 711 always remain in cooperation, that is, the first adapter 710 can be regarded as rotating relative to the second adapter 720 along the central axis of the first clip structure 711, or the second adapter 720 can be regarded as rotating relative to the first adapter 710 along the central axis of the second clip structure 721, so that the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 can be adjusted, so that the adapter assembly 700 can be adjusted to a straight shape or a curved shape, and the bending angle of the adapter assembly 700 can be adjusted according to the installation position of the cabinet air conditioner.

[0286] In some embodiments of the present invention, Fig.35As shown, the first clamping structure 711 includes a stop portion 712 , a main body portion 713 and a clamping portion 714 .

[0287] The plane where the stop portion 712 is located is perpendicular to the central axis of the first clamping structure 711, and the second clamping structure 721 stops at the stop portion 712, the main body 713 is connected to the stop portion 712 and surrounds the second clamping structure 721, the clamping portion 714 is connected to the main body 713 and protrudes from the inner circumference of the main body 713, and the second clamping structure 721 is clamped between the stop portion 712 and the clamping portion 714.

[0288] Therefore, when the second clamping structure 721 is inserted into the first clamping structure 711, the end of the second clamping structure 721 facing the first clamping structure 711 can stop at the stop portion 712, and the stop portion 712 can limit the insertion position of the second clamping structure 721 to avoid the plug-in size of the first adapter 710 and the second adapter 720 being too large, and the clamping portion 714 can be clamped to the side of the second clamping structure 721 that is away from the stop portion 712, so that the position of the second clamping structure 721 can be fixed by the clamping portion 714 and the stop portion 712, so that the first adapter 710 and the second adapter 720 can be connected more stably, avoiding the first adapter 710 and the second adapter 720 from separating.

[0289] Moreover, the main body 713 can surround the second clamping structure 721 from the outer peripheral surface of the second clamping structure 721. On the one hand, the contact area between the second clamping structure 721 and the first clamping structure 711 can be increased, so that the connection strength between the second clamping structure 721 and the first clamping 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 radial direction of the second clamping structure 721 can be limited by the main body 713, thereby avoiding radial misalignment between the first adapter 710 and the second adapter 720, and the structural setting is more reasonable.

[0290] In some embodiments of the present invention, Fig.35 As shown, the clamping portion 714 is a buckle 632 and is provided in plurality, and the plurality of buckles 632 are arranged at intervals along the circumference of the main body 713 .

[0291] Specifically, a plurality of buckles 632 are disposed at one end of the main body 713 away from the stop portion 712, and the buckles 632 protrude from the inner circumferential surface of the main body 713, so that when the second clip structure 721 is inserted into the first clip structure 711, the plurality of buckles 632 can stop the second clip structure 721 at multiple circumferential positions of the second clip structure 721 to prevent the second clip structure 721 from detaching from the first clip structure 711, thereby preventing the first adapter 710 and the second adapter 720 from separating from each other.

[0292] Furthermore, by providing a plurality of buckles 632, the connection stability between the first clip structure 711 and the second clip structure 721 can be improved, and the plurality of buckles 632 can simultaneously clip the second clip structure 721, thereby avoiding the connection failure of a single buckle 632 that causes the connection failure of the first clip structure 711 and the second clip structure 721, thereby further improving the connection reliability between the first adapter 710 and the second adapter 720.

[0293] In some embodiments of the present invention, Fig.35 As shown, the main body 713 is provided with a plurality of deformation portions 715 , and the plurality of deformation portions 715 are respectively disposed on two opposite sides of the buckle 632 .

[0294] By providing the deformation portion 715, the structural strength of the main body 713 on both sides of the buckle 632 can be weakened, so that when the second clip structure 721 is inserted into the first clip structure 711, the buckle 632 can be elastically deformed more easily, thereby making the installation of the first adapter 710 and the second adapter 720 more labor-saving, more convenient and quicker, and avoiding damage to the clip portion 714 and the second clip structure 721 during the installation process.

[0295] In some embodiments of the present invention, the second adapter 720 has a first position and a second position. When the second adapter 720 is in 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 in the second position, the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is α, and α satisfies: 90°≤α≤135°.

[0296] That is, the second adapter 720 and the first adapter 710 have two extreme positions for relative rotation. When the second adapter 720 is located at the first position, that is, the second adapter 720 and the first adapter 710 are relatively rotated to the first extreme position, the adapter assembly 700 can be in a straight line at this time. When the second adapter 720 is located at the second position, that is, the second adapter 720 and the first adapter 710 are relatively rotated to the second extreme position, the adapter assembly 700 can be in a bent shape at this time, and the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 is between 90° and 135°. Therefore, the second adapter 720 can rotate between the first position and the second position, so that the bending angle of the adapter assembly 700 can be adjusted.

[0297] Furthermore, by setting °90≤α≤135°, the first adapter 710 and the second adapter 720 can be relatively rotated according to the installation position of the cabinet air conditioner, so that the angle between the first adapter 710 and the second adapter 720 can be rotated to a suitable angle, thereby facilitating the connection of the adapter assembly 700 to the fresh air inlet duct 730 and the casing 100, respectively.

[0298] In other embodiments of the present invention, Figure 30-Figure 39 As shown, the adapter assembly 700 includes a first adapter 710 and a second adapter 720 .

[0299] The first adapter 710 is connected to the housing 100 and communicates with the fifth air inlet 160 , the second adapter 720 is connected to the fresh air inlet pipe 730 , and the extension direction of the second adapter 720 is adjustable relative to the extension direction of the first adapter 710 .

[0300] In this way, when the fifth air inlet 160 is facing the wall 740, the central axis of the fresh air inlet duct 730 can coincide with the central axis of the fifth air inlet 160. At this time, the extension direction of the first adapter 710 and the extension direction of the second adapter 720 can be adjusted to extend in the same direction, that is, the adapter assembly 700 can be linear, which is convenient for connecting the first adapter 710 and the casing 100 and the second adapter 720 and the fresh air inlet duct 730.

[0301] When the fifth air inlet 160 is diagonally facing the wall 740, the central axis of the fresh air inlet duct 730 can be inclined relative to the central axis of the fifth air inlet 160. At this time, the extension direction of the first adapter 710 and the extension direction of the second adapter 720 can be adjusted to be relatively inclined, that is, the adapter assembly 700 can be bent so that the extension direction of the first adapter 710 can coincide with the central axis of the fifth air inlet 160, and the extension direction of the second adapter 720 can coincide with the central axis of the fresh air duct, which facilitates the connection between the first adapter 710 and the casing 100 and the second adapter 720 and the fresh air inlet duct 730, and is beneficial to reducing the space occupied by the adapter assembly 700, so that the installation space of the cabinet air conditioner can be smaller.

[0302] The cabinet air conditioner according to some embodiments of the utility model can meet the requirements of different installation environments, and has the advantages of high installation efficiency, convenient installation and small installation space.

[0303] In some embodiments of the utility model, the first adapter 710 is provided with a second clip structure 721, the central axis of the first adapter 710 is perpendicular to the first section, and the central axis of the second clip structure 721 is perpendicular to the second section, and the angle between the first section and the second section is β, and β satisfies: 10°≤β≤45°.

[0304] In this way, there can be an angle difference between the central axis of the first adapter 710 and the central axis of the second clip structure 721. When the second clip structure 721 rotates relative to the second adapter 720, it can drive the first adapter 710 to rotate, and the first adapter 710 can be bent in different directions relative to the second adapter 720, so that the angle difference between the first adapter 710 and the second adapter 720 can be adjusted, so that the first adapter 710 and the second adapter 720 can form a straight line or a bend with different angles.

[0305] Moreover, by making β satisfy 10°≤β≤45°, on the one hand, it is possible to avoid the angle between the first section and the second section being too small, so that the angle between the central axis of the first adapter 710 and the central axis of the second clamping structure 721 can be larger, and during the rotation of the second clamping structure 721 relative to the second adapter 720, the range of change of the angle between the first adapter 710 and the second adapter 720 can be larger, so as to facilitate the adjustment of the shape of the adapter assembly 700 so that the cabinet air conditioner can meet the requirements of different installation environments; on the other hand, it is possible to avoid the angle between the first section and the second section being too large, so as to avoid the first adapter 710 being bent too much relative to the second adapter 720 during the rotation of the second clamping structure 721 relative to the second adapter 720, so that the airflow in the adapter assembly 700 can remain unobstructed, and it is possible to avoid the angle between the central axis of the first adapter 710 and the central axis of the second clamping structure 721 being too large, which leads to a decrease in the structural strength of the first adapter 710 and the second clamping structure 721, so as to ensure that the overall structural strength of the adapter assembly 700 can be high.

[0306] The cabinet air conditioner according to some embodiments of the present utility model is described below with reference to the accompanying drawings.

[0307] like Figure 40-51 As shown in the figure, the cabinet air conditioner according to the embodiment of the present utility model includes a main body, which includes a casing 100, a heat exchanger and a ventilation component 200.

[0308] The main body has an upper chamber and a lower chamber below the upper chamber. The heat exchanger is arranged in the upper chamber, and the ventilation component 200 is arranged in the lower chamber. The ventilation component 200 is used to send outdoor air to indoors, and send indoor air to the outdoors or outdoors.

[0309] 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 a motor 500 .

[0310] The first air duct member 210 is arranged in the lower chamber, and a first air duct 201 is formed in the first air duct member 210, and outdoor air enters the room through the first air duct 201. The second air duct member 220 is arranged in the lower chamber, and a second air duct 202 is formed in the second air duct member 220, and indoor air is delivered to the indoor or outdoor through the second air duct 202. The first fan 300 is arranged in the second air duct 202 to deliver indoor air to the indoor or outdoor. The second fan 400 is arranged in the first air duct 201 to deliver outdoor air to the indoor. The motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510.

[0311] Among them, one of the first fan 300 and the second fan 400 is provided with a first stop part 320, and the other is provided with a second stop part 420, and the first stop part 320 and the second stop part 420 cooperate with each other; when the motor 500 is working, the motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first stop part 320 and the second stop part 420 cooperate to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0312] According to some embodiments of the cabinet air conditioner of the utility model, the main body is provided with an upper chamber and a lower chamber, the heat exchanger is provided in the upper chamber, and the ventilation component 200 is provided in the lower chamber, and the ventilation component 200 is used to send outdoor air to the room, and send indoor air to the outside or the outside. In this way, the ventilation component 200 can introduce outdoor air into the room through the first air duct 201, and then purify the indoor air through the outdoor fresh air, or the ventilation component 200 can discharge the indoor air to the outside, so that the relatively dirty indoor air can be discharged to the outside, so as to quickly purify the indoor air after the outdoor air is introduced, or the ventilation component 200 can suck the indoor air into the casing 100 and exchange heat with the heat exchanger before discharging it into the room, so that indoor cooling or heating can be quickly achieved.

[0313] Furthermore, the first air duct member 210 is disposed in the lower chamber, a first air duct 201 is formed in the first air duct member 210, outdoor air enters the room through the first air duct 201, the second air duct member 220 is disposed in the lower chamber, a second air duct 202 is formed in the second air duct member 220, indoor air is sent to the room or the outside through the second air duct 202, the first fan 300 is disposed in the second air duct 202 to send indoor air to the room or the outside, and the second fan 400 is disposed in the first air duct 201 to send outdoor air to the room. In this way, the first air duct member 210 can guide outdoor fresh air, and the second air duct member 220 can guide indoor air, so that the flow of outdoor fresh air and indoor air is separated, and interference between outdoor air and indoor air is avoided during flow, so that the air flow inside the cabinet air conditioner is smoother.

[0314] Moreover, the motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510. That is, the first fan 300 and the second fan 400 can share one motor 500, thereby reducing the number of motors 500, making the cabinet air conditioner have fewer parts, assembling more conveniently and reducing the space occupied by the motor 500, thereby facilitating reducing the volume of the ventilation component 200.

[0315] In addition, one of the first fan 300 and the second fan 400 is provided with a first stop portion 320, and the other is provided with a second stop portion 420, and the first stop portion 320 and the second stop portion 420 cooperate with each other; when the motor 500 is working, the motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first stop portion 320 and the second stop portion 420 cooperate with each other to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0316] It should be noted that the first anti-rotation part 320 cooperates with the second anti-rotation part 420 to prevent the second fan 400 and the first fan 300 from rotating in the circumferential direction of the output shaft 510, that is, the second fan 400 and the first fan 300 will not rotate relative to each other, and the second fan 400 and the first fan 300 can rotate at the same frequency as the output shaft 510. At the same time, the first anti-rotation part 320 and the second anti-rotation part 420 cooperate to position the assembly of the second fan 400 and the first fan 300.

[0317] Therefore, even if the first fan 300 and the second fan 400 are subject to different wind resistances, after the first stop 320 and the second stop 420 cooperate, the fan with a faster speed can also drive the fan with a slower speed to rotate, and at the same time, the fan with a faster speed is affected by the fan with a slower speed and the speed of the fan decreases. For example, the wind resistance of the second fan 400 is larger and the wind resistance of the first fan 300 is smaller. At this time, the speed of the second fan 400 will be lower than the speed of the first fan 300. After the first stop 320 and the second stop 420 cooperate, the first fan 300 can drive the second fan 400 to rotate faster, and at the same time, the speed of the first fan 300 is affected by the second fan 400 and the speed is reduced, so that the first fan 300 and the second fan 400 can maintain a consistent speed, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the rotation noise and vibration of the first fan 300 and the second fan 400 during rotation, and providing a better user experience.

[0318] In this way, the cabinet air conditioner according to some embodiments of the present invention can make the first fan 300 and the second fan 400 rotate at the same frequency, which is beneficial to reduce vibration and noise and provide a better user experience.

[0319] In some embodiments of the present invention, Fig.44 and Fig.45 As shown, a first hub 330 is disposed on a side of the first fan 300 facing the second fan 400 , and the first hub 330 protrudes toward the second fan 400 to form a first matching portion 340 .

[0320] like Fig.44 and Fig.45 As shown, a second hub 430 is provided on the side of the second fan 400 facing the first fan 300, and the second hub 430 protrudes toward the first fan 300 to form a second matching portion 440; wherein, one of the first matching portion 340 and the second matching portion 440 is provided with a first stop portion 320, and the other is provided with a second stop portion 420.

[0321] That is, the first mating portion 340 may be provided with a first stop portion 320 , and the second mating portion 440 may be provided with a second stop portion 420 ; or, the first mating portion 340 may be provided with a second stop portion 420 , and the second mating portion 440 may be provided with a first stop portion 320 .

[0322] By protruding the first matching portion 340 toward the second fan 400, and the second matching portion 440 toward the first fan 300, the first matching portion 340 and the second matching portion 440 can be closer to each other, so as to facilitate the contact and matching between the first matching portion 340 and the second matching portion 440, and enable the first stop portion 320 and the second stop portion 420 to be stably and reliably matched together to avoid separation of the first stop portion 320 and the second stop portion 420, thereby ensuring that the second fan 400 and the first fan 300 can rotate at the same frequency to reduce the vibration and noise of the cabinet air conditioner.

[0323] Furthermore, if Fig.46 and Fig.49 As shown, the first stop portion 320 is a stop protrusion and is provided in plurality, and the plurality of stop protrusions are arranged along the circumference of the first matching portion 340; the second stop portion 420 is a stop groove and is provided in plurality, and the plurality of stop grooves are arranged along the circumference of the second matching portion 440, and the plurality of stop protrusions are inserted into the plurality of stop grooves in a one-to-one correspondence.

[0324] By providing a plurality of anti-rotation protrusions and anti-rotation grooves, the cooperation between the anti-rotation protrusions and the anti-rotation grooves can be made more stable and reliable, thereby avoiding failure of the connection between the second fan 400 and the first fan 300, and more effectively ensuring the rotation synchronization of the second fan 400 and the first fan 300, so that the rotation noise and rotation vibration of the second fan 400 and the first fan 300 are smaller, and the user experience is better.

[0325] Moreover, by configuring the first stop portion 320 and the second stop portion 420 to be a combination of a protrusion and a groove, it is not only helpful to simplify the structure of the first stop portion 320 and the second stop portion 420 and facilitate processing and manufacturing, but also 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 the circumference of the output shaft 510, the stop protrusion can be inserted into the stop groove, and the assembly efficiency is higher.

[0326] Of course, it is understandable that the first stop portion 320 and the second stop portion 420 can also be other matching structures. For example, the first stop portion 320 and the second stop portion 420 can both be set as protrusions, and the protrusions on the first matching portion 340 and the protrusions on the second matching portion 440 are staggered circumferentially so that the protrusions on the first matching portion 340 and the protrusions on the second matching portion 440 can abut against each other, so that the two fans can rotate at the same frequency.

[0327] In some embodiments of the present invention, Fig.46 and Fig.49 As shown, the anti-rotation protrusion has a first side surface 321 and a second side surface 322 relative to each other in the circumferential direction of the first matching portion 340, and is close to the anti-rotation groove along the axial direction of the first matching portion 340, and the first side surface 321 and the second side surface 322 are close to each other; the anti-rotation groove has a first wall surface 421 and a second wall surface 422 relative to each other in the circumferential direction of the second matching portion 440, and is away from the anti-rotation protrusion along the axial direction of the second matching portion 440, and the first wall surface 421 and the second wall surface 422 are close to each other.

[0328] That is to say, the first side surface 321 and the second side surface 322 can be constructed as inclined surfaces, and the first wall surface 421 and the second wall surface 422 can also be constructed as inclined surfaces. It should be noted that the inclination angle of the first side surface 321 and the inclination angle of the first wall surface 421 can be the same, and the inclination angle of the second side surface 322 and the inclination angle of the second wall surface 422 can be the same.

[0329] In this way, when the anti-rotation protrusion is inserted into the anti-rotation groove, the first side surface 321 and the second wall surface 422 can abut against each other with a larger contact area, and the second side surface 322 and the second wall surface 422 can abut against each other with a larger contact area, so that the anti-rotation protrusion and the anti-rotation groove can fit more closely, and the matching stability of the anti-rotation protrusion and the anti-rotation groove is further improved, ensuring that the second fan 400 and the first fan 300 will not rotate or shake relative to each other, and more effectively reducing the vibration and rotation noise of the second fan 400 and the first fan 300.

[0330] Moreover, with such a configuration, the width of the end of the anti-rotation protrusion away from the first matching portion 340 can be smaller, while the opening width of the anti-rotation groove can be larger, which facilitates the insertion of the anti-rotation protrusion into the anti-rotation groove, that is, the anti-rotation protrusion and the anti-rotation 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 improving the assembly efficiency.

[0331] In some embodiments of the present invention, Fig.46 and Fig.49 As shown, along the radial direction outward of the first matching portion 340 , the first side surface 321 and the second side surface 322 are away from each other; along the radial direction outward of the second matching portion 440 , the first wall surface 421 and the second wall surface 422 are away from each other.

[0332] It can be understood that, along the radial direction of the first matching part 340, the closer to the central axis of the first matching part 340, the smaller the radius of the first matching part 340, and the smaller the space for arranging the anti-rotation protrusion in the circumferential direction. Moreover, along the radial outward direction of the first matching part 340, the radius of the first matching part 340 gradually increases, and the space for arranging the anti-rotation protrusion in the circumferential direction also gradually increases. The distance between the first side surface 321 and the second side surface 322 gradually increases, so that the anti-rotation protrusion can make full use of the space on the first matching part 340, and the distance between adjacent anti-rotation protrusions can be avoided, and the layout is more reasonable.

[0333] Similarly, along the radial direction of the second matching part 440, the closer to the central axis of the second matching part 440, the smaller the radius of the second matching part 440, and the smaller the space for arranging the anti-rotation groove in the circumferential direction. Moreover, along the radial outward direction of the second matching part 440, the radius of the second matching part 440 gradually increases, and the space for arranging the anti-rotation groove in the circumferential direction also gradually increases. The distance between the first wall 421 and the second wall 422 gradually increases, so that the anti-rotation groove can make full use of the space on the second matching part 440, and can avoid the adjacent anti-rotation grooves being too close, and the layout is more reasonable.

[0334] Moreover, the first side surface 321 and the second side surface 322 can also be constructed as inclined surfaces in the radial direction of the first matching portion 340, and the first wall surface 421 and the second wall surface 422 can also be constructed as inclined surfaces in the radial direction of the second matching portion 440. This further increases the contact area between the first side surface 321 and the first wall surface 421, and increases the contact area between the second side surface 322 and the second wall surface 422. The anti-rotation protrusion and the anti-rotation groove are more closely matched, and the connection stability between the first fan 300 and the second fan 400 is higher.

[0335] In some embodiments of the present invention, Fig.46 and Fig.49As shown, the side of the anti-rotation protrusion away from the center of the first matching part 340 is constructed as a third side surface 323, and is close to the anti-rotation groove along the axial direction of the first matching part 340, and the third side surface 323 is inclined toward the center of the first matching part 340; the side of the anti-rotation groove away from the center of the second matching part 440 is constructed as a third wall surface 423, and is away from the anti-rotation protrusion along the axial direction of the second matching part 440, and the third wall surface 423 is inclined toward the center of the second matching part 440.

[0336] That is to say, the third side surface 323 can also be constructed as a slope, and the third wall surface 423 can also be constructed as a slope, so that the contact area between the third side surface 323 and the third wall surface 423 is also larger. After the anti-rotation protrusion is inserted into the anti-rotation groove, the third side surface 323 and the third wall surface 423 can abut against each other, and the fit between the anti-rotation protrusion and the anti-rotation groove can be tighter, which further improves the matching stability of the anti-rotation protrusion and the anti-rotation groove, ensuring that the second fan 400 and the first fan 300 will not rotate or shake relative to each other, and more effectively reducing the vibration and rotation noise of the second fan 400 and the first fan 300.

[0337] Moreover, the cooperation between the third side surface 323 and the third wall surface 423 can guide the cooperation between the anti-rotation protrusion and the anti-rotation groove, and further guide the assembly of the second fan 400 and the first fan 300, which is helpful to simplify the assembly of the second fan 400 and the first fan 300 and improve the assembly efficiency.

[0338] In some embodiments of the present invention, Fig.50 and Fig.51 As shown, the first fan 300 also includes a first insert 350, which is fixed in the first hub 330, and the first insert 350 is sleeved on the output shaft 510 and is transmission connected to the output shaft 510; the second fan 400 also includes a second insert 450, which is fixed in the second hub 430, and the second insert 450 is sleeved on the output shaft 510 and is transmission connected to the output shaft 510.

[0339] Among them, the first insert 350 can be formed by injection molding and arranged in the first hub 330, and the hardness of the first insert 350 can be greater than the hardness of the first hub 330, so that the matching stability of the first fan 300 and the output shaft 510 can be improved, and the gap between the first insert 350 and the output shaft 510 can be smaller, and the output shaft 510 can drive the first fan 300 to rotate more stably. In addition, the second insert 450 can be formed by injection molding and arranged in the second hub 430, and the hardness of the second insert 450 can be greater than the hardness of the second hub 430, so that the matching stability of the second fan 400 and the output shaft 510 can be improved, and the gap between the second insert 450 and the output shaft 510 can be smaller, and the output shaft 510 can drive the second fan 400 to rotate more stably.

[0340] Furthermore, if Fig.51 As shown, the outer contour of the output shaft 510 is non-circular, the first insert 350 is constructed with a first anti-rotation portion 351 adapted to the outer contour of the output shaft 510, the second insert 450 is constructed with a second anti-rotation portion 451 adapted to the outer contour of the output shaft 510, and the output shaft 510 is inserted through the first anti-rotation portion 351 and the second anti-rotation portion 451.

[0341] The first anti-rotation portion 351 may be configured as a first anti-rotation hole, and the second anti-rotation portion 451 may be configured as a second anti-rotation hole.

[0342] In this way, after the output shaft 510 passes through the first anti-rotation portion 351 , the output shaft 510 and the first insert 350 will not rotate relative to each other, that is, the output shaft 510 and the first fan 300 will not rotate relative to each other, so that the first fan 300 can be driven to rotate by the output shaft 510 .

[0343] Furthermore, after the output shaft 510 passes through the second anti-rotation portion 451 , the output shaft 510 and the second insert 450 will not rotate relative to each other, that is, the output shaft 510 and the second fan 400 will not rotate relative to each other, so that the second fan 400 can be driven to rotate by the output shaft 510 .

[0344] It is understandable that, in order to facilitate assembly, there will be a certain gap between the output shaft 510 and the first anti-rotation portion 351, and there will be a certain gap between the output shaft 510 and the second anti-rotation portion 451. 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 will shake relative to each other. In the embodiment of the utility model, after the second fan 400 and the first fan 300 are connected and positioned by the first anti-rotation portion 320 and the second anti-rotation portion 420, the second fan 400 and the first fan 300 will not rotate relative to each other or the relative rotation will be small, thereby reducing the rotation noise and rotation vibration of the second fan 400 and the first fan 300, and providing a better user experience.

[0345] like Figure 40-Figure 51 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a main body, which includes a casing 100 , a heat exchanger and a ventilation assembly 200 .

[0346] The main body has an upper chamber and a lower chamber below the upper chamber. The heat exchanger is arranged in the upper chamber, and the ventilation component 200 is arranged in the lower chamber. The ventilation component 200 is used to send outdoor air to indoors, and send indoor air to the outdoors or outdoors.

[0347] 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 a motor 500 .

[0348] Specifically, the main body is provided with an upper chamber and a lower chamber, the heat exchanger is provided in the upper chamber, the ventilation assembly 200 is provided in the lower chamber, and the ventilation assembly 200 is used to send outdoor air to the room, and send indoor air to the outside or the outside. In this way, the ventilation assembly 200 can introduce outdoor air into the room through the first air duct 201, and then purify the indoor air through the outdoor fresh air, or the ventilation assembly 200 can discharge the indoor air to the outside, so that the relatively dirty indoor air can be discharged to the outside, so as to quickly purify the indoor air after the outdoor air is introduced, or the ventilation assembly 200 can suck the indoor air into the casing 100 and exchange heat with the heat exchanger before discharging it into the room, so as to quickly realize indoor cooling or heating.

[0349] Furthermore, the first air duct member 210 is disposed in the lower chamber, a first air duct 201 is formed in the first air duct member 210, outdoor air enters the room through the first air duct 201, the second air duct member 220 is disposed in the lower chamber, a second air duct 202 is formed in the second air duct member 220, indoor air is sent to the room or the outside through the second air duct 202, the first fan 300 is disposed in the second air duct 202 to send indoor air to the room or the outside, and the second fan 400 is disposed in the first air duct 201 to send outdoor air to the room. In this way, the first air duct member 210 can guide outdoor fresh air, and the second air duct member 220 can guide indoor air, so that the flow of outdoor fresh air and indoor air is separated, and interference between outdoor air and indoor air is avoided during flow, so that the air flow inside the cabinet air conditioner is smoother.

[0350] Moreover, the motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510. That is, the first fan 300 and the second fan 400 can share one motor 500, thereby reducing the number of motors 500, making the cabinet air conditioner have fewer parts, assembling more conveniently and reducing the space occupied by the motor 500, thereby facilitating reducing the volume of the ventilation component 200.

[0351] In addition, the first fan 300 and the second fan 400 are connected to rotate at the same frequency.

[0352] As a result, the second fan 400 and the first fan 300 will not rotate relative to each other, and the second fan 400 and the first fan 300 can rotate at the same frequency as the output shaft 510. Even if the first fan 300 and the second fan 400 are subject to different wind resistances, after the first fan 300 and the second fan 400 are connected, the fan with a faster rotation speed can also drive the fan with a slower rotation speed to rotate, and at the same time, the fan with a faster rotation speed is affected by the fan with a slower rotation speed and its rotation speed decreases. For example, the wind resistance of the second fan 400 is larger and the wind resistance of the first fan 300 is smaller. At this time, the rotation speed of the second fan 400 will be lower than the rotation speed of the first fan 300. After the first fan 300 and the second fan 400 are connected, the first fan 300 can drive the second fan 400 to rotate faster, and at the same time, the first fan 300 is affected by the second fan 400 and its rotation speed decreases, so that the first fan 300 and the second fan 400 can maintain a consistent rotation speed, and the first fan 300 and the second fan 400 can rotate at the same frequency, which is beneficial to reducing the rotation noise and vibration of the first fan 300 and the second fan 400 during rotation, and providing a better user experience.

[0353] According to some embodiments of the present invention, the cabinet air conditioner can make the first fan 300 and the second fan 400 rotate at the same frequency, which is beneficial to reduce vibration and noise and provide a better user experience.

[0354] In some embodiments of the present invention, Fig.42 , Fig.46 and Fig.49 As shown, a rotation-stopping protrusion is provided on a side of the first fan 300 facing the second fan 400, and a rotation-stopping groove is provided on a side of the second fan 400 facing the first fan 300, and the rotation-stopping protrusion is inserted into the rotation-stopping groove.

[0355] By configuring the connection between the first fan 300 and the second fan 400 as a combination of a protrusion and a groove, it is not only helpful to simplify the connection structure of the first fan 300 and the second fan 400 and facilitate processing and manufacturing, but also 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 the circumference of the output shaft 510, the anti-rotation protrusion can be inserted into the anti-rotation groove, and the first fan 300 and the second fan 400 are connected, and the assembly efficiency of the first fan 300 and the second fan 400 is higher.

[0356] Moreover, after the anti-rotation protrusion is inserted into the anti-rotation groove, the side surface of the anti-rotation protrusion can abut against the wall surface of the anti-rotation groove, and the anti-rotation protrusion and the anti-rotation groove will not rotate relative to each other, thereby realizing the synchronous rotation of the first fan 300 and the second fan 400.

[0357] The cabinet air conditioner according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0358] like Figure 52-Figure 58 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a main body, which includes a casing 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 a motor 500.

[0359] The heat exchanger is arranged in the upper chamber, 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, 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, indoor air is sent to the indoor or outdoor through the second air duct 202, the first fan 300 is arranged in the second air duct 202 to send indoor air to the indoor or outdoor, the second fan 400 is arranged in the first air duct 201 to send outdoor air to the indoor, the motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate.

[0360] 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 the free end of the output shaft 510 is rotatably mounted on the air duct member fixing portion 227 .

[0361] Lubricating oil may be applied to the connection 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 the noise of the output shaft 510 during rotation.

[0362] According to some embodiments of the cabinet air conditioner of the present invention, an upper chamber and a lower chamber are set on the main body, a heat exchanger is set in the upper chamber, and a first duct member 210 is set in the lower chamber, a first duct member 201 is formed in the first duct member 210, and outdoor air enters the room through the first duct 201, a second duct member 220 is set in the lower chamber, a second duct member 202 is formed in the second duct member 220, and indoor air is sent to the indoor or outdoor through the second duct 202, a first fan 300 is set in the second duct 202 to send indoor air to the indoor or outdoor, and a second fan 400 is set in the first duct 201 to send outdoor air to the indoor.

[0363] In this way, the second fan 400 can introduce outdoor air into the room through the first air duct 201, and then purify the indoor air with the outdoor fresh air. Alternatively, the first fan 300 can discharge the indoor air to the outside, so that the dirtier air in the room can be discharged to the outside, so as to quickly purify the indoor air after the outdoor air is introduced. Alternatively, the first fan 300 can suck the indoor air into the casing 100, exchange heat with the heat exchanger, and then discharge it into the room, so as to quickly achieve indoor cooling or heating.

[0364] Moreover, the first air duct member 210 can guide the outdoor fresh air, while the second air duct member 220 can guide the indoor air, so as to separate the flow of the outdoor fresh air and the indoor air, avoid interference between the outdoor air and the indoor air during flow, and make the air flow inside the cabinet air conditioner smoother.

[0365] Furthermore, the motor 500 has a single output shaft 510, and the first fan 300 and the second fan 400 are drivingly connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate. In other words, the first fan 300 and the second fan 400 can share one motor 500, thereby reducing the number of motors 500, making the number of parts of the cabinet air conditioner smaller, making assembly more convenient, and reducing the space occupied by the motor 500, which is convenient for reducing the volume of the cabinet air conditioner.

[0366] In addition, 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 the free end of the output shaft 510 is rotatably mounted on the air duct member fixing portion 227 .

[0367] Specifically, the motor 500 can be arranged in the first air duct member 210, and the output shaft 510 of the motor 500 extends in the direction close to the second air duct member 220. In this case, the second air duct member 220 can be provided with a duct member fixing portion 227, and the end of the output shaft 510 away from the motor 500, that is, the free end of the output shaft 510 can be installed on the duct member fixing portion 227 on the second air duct member 220; or, the motor 500 can be arranged in the second air duct member 220, and the output shaft 510 of the motor 500 extends in the direction close to the first air duct member 210. In this case, the first air duct member 210 can be provided with a duct member fixing portion 227, and the end of the output shaft 510 away from the motor 500, that is, the free end of the output shaft 510 can be installed on the duct member fixing portion 227 on the first air duct member 210. In this way, the structure of the first air duct member 210 and the structure of the second air duct member 220 can be arranged according to the layout of the motor 500, which can not only ensure that the free end of the output shaft 510 can be installed on the air duct member fixing part 227, but also avoid position interference between the air duct member fixing part 227 and the motor 500 or other components.

[0368] Moreover, by connecting the free end of the output shaft 510 and the duct member fixing portion 227, the free end of the output shaft 510 can be connected and fixed to the first duct member 210 or the second duct member 220, and the first duct member 210 or the second duct member 220 can support the free end of the output shaft 510, thereby improving the rotation stability of the output shaft 510, and the output shaft 510 is not prone to shaking, thereby greatly reducing the vibration of the output shaft 510 during rotation and the noise generated by the vibration. The vibration and noise during the operation of the cabinet air conditioner are smaller, and the user experience is better.

[0369] In this way, the cabinet air conditioner according to some embodiments of the present invention can enhance the support for the output shaft 510 of the motor 500, the rotation of the output shaft 510 is more stable, and the vibration and rotation noise are smaller, and the user experience is better.

[0370] In some embodiments of the present invention, Fig.53 As shown, the duct member fixing portion 227 extends along the axial direction of one of the first fan 300 and the second fan 400 , and the duct member fixing portion 227 is protruded toward the output shaft 510 .

[0371] For example, if the first duct member 210 is provided with a duct member fixing portion 227, the duct member fixing portion 227 can extend along the axial direction of the first fan 300, and if the second duct member 220 is provided with a duct member fixing portion 227, the duct member fixing portion 227 can extend along the axial direction of the second fan 400. Such a configuration not only facilitates the installation of the free end of the output shaft 510 on the duct member fixing portion 227, making assembly more convenient, but also the shielding area of ​​the duct member fixing portion 227 in the radial direction of the first duct member 210 or the second duct member 220 can be smaller, thereby preventing the duct member fixing portion 227 from excessively shielding the air inlet, so as to facilitate indoor air to enter the first duct member 210, or facilitate outdoor fresh air to enter the second duct member 220.

[0372] In addition, by protruding the air duct member fixing portion 227 toward 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, the distance between the air duct member fixing portion 227 and the free end of the output shaft 510 can be closer, so that the output shaft 510 can be inserted into the air duct member fixing portion 227, and the assembly is more convenient.

[0373] In some embodiments of the present invention, Fig.53As shown, the central axis of the duct member fixing portion 227 coincides with the central axis of the output shaft 510, so that the duct member fixing portion 227 and the output shaft 510 can coincide, and the free end of the output shaft 510 can be inserted into the duct member fixing portion 227 to support the output shaft 510 through the duct member fixing portion 227, so that the rotation of the output shaft 510 is more stable, and the duct member fixing portion 227 and the output shaft 510 will not be staggered in the radial direction of the output shaft 510. On the one hand, it can simplify the assembly of the output shaft 510 and the duct member fixing portion 227, and on the other hand, it can reduce the space occupied by the output shaft 510 and the duct member fixing portion 227 in the radial direction of the first duct member 210 or the second duct member 220, which is convenient for layout and can avoid position interference between components.

[0374] In addition, in some embodiments, Fig.53 As shown, the outer diameter of the air duct member fixing portion 227 can be gradually reduced along the axial direction of the air duct member fixing portion 227 gradually approaching the output shaft 510, so that the outer diameter of the connection between the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 can be larger, the connection strength between the air duct member fixing portion 227 and the first air duct member 210 or the second air duct member 220 is higher, and the stability of the air duct member fixing portion 227 is better, that is, the air duct member fixing portion 227 is not easy to shake, so that 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 smaller, and the user experience is better.

[0375] In some embodiments of the present invention, Fig.57 As shown, the output shaft 510 includes a transmission section 511, an output shaft fixing portion 512 and a support section 513. The output shaft fixing portion 512 may be a threaded section.

[0376] The first fan 300 and the second fan 400 are sleeved on the transmission section 511 and are in transmission connection with the transmission section 511. One end of the output shaft fixing portion 512 is connected to the transmission section 511, and a threaded fastener 520 is provided on the output shaft fixing portion 512. The first fan 300 and the second fan 400 are stopped between the motor 500 and the threaded fastener 520. The support section 513 is connected to the other end of the output shaft fixing portion 512, and the support section 513 can be rotatably inserted into the air duct fixing portion 227.

[0377] The outer contour of the transmission section 511 may be configured as a non-circular shape, so that after the first fan 300 and the second fan 400 are sleeved on the transmission section 511 , the transmission section 511 may drive the second fan 400 and the first fan 300 to rotate.

[0378] In addition, the threaded fastener 520 can be a nut. After the first fan 300 and the second fan 400 are sleeved on the transmission section 511, the nut can be threadedly connected to the output shaft fixing portion 512, so that the threaded fastener 520 can be used to limit the first fan 300 and the second fan 400, so that the first fan 300 and the second fan 400 can be more stably sleeved on the transmission section 511, avoiding position displacement of the first fan 300 and the second fan 400, and further reducing the vibration and noise generated by the second fan 400 and the first fan 300 during rotation.

[0379] Moreover, by providing the support section 513, the support section 513 can extend beyond the side of the threaded fastener 520 facing away from the second fan 400, so that the support section 513 and the duct member fixing portion 227 can be connected, and the duct member fixing portion 227 can support the output shaft 510 by supporting the support section 513, thereby avoiding positional interference between the output shaft fixing portion 512 and the threaded fastener 520 and the duct member fixing portion 227, and the free end of the output shaft 510 is easier to install in the duct member fixing portion 227, and the connection between the output shaft 510 and the duct member fixing portion 227 is more stable and reliable.

[0380] In some embodiments of the present invention, Fig.54 and Fig.58 As shown, the air duct member fixing portion 227 is provided with a shaft sleeve fixing structure 228 , a shaft sleeve 560 is installed in the shaft sleeve fixing structure 228 , and the output shaft 510 is passed through the shaft sleeve 560 .

[0381] The shaft sleeve fixing structure 228 may be configured as a fixing hole.

[0382] Specifically, the sleeve 560 can be fixed in the sleeve fixing structure 228 of the duct component fixing portion 227, and the output shaft 510 is passed through the sleeve 560, and the output shaft 510 rotates relative to the sleeve 560. On the one hand, the sleeve 560 can be used to support the output shaft 510 to reduce the vibration of the output shaft 510 during rotation. On the other hand, the resistance of the output shaft 510 during rotation can be reduced, and the rotational friction between the sleeve 560 and the output shaft 510 can be smaller, thereby reducing the wear of the output shaft 510 and making the rotation of the output shaft 510 easier.

[0383] Furthermore, if Fig.56 As shown, the sleeve fixing structure 228 includes a receiving section 2281 and a stopping section 2282 .

[0384] The stop section 2282 is disposed on a side of the accommodating section 2281 facing away from the output shaft 510 , wherein the inner diameter of the accommodating section 2281 is larger than the inner diameter of the stop section 2282 , and the sleeve 560 is installed on the accommodating section 2281 and stopped at the stop section 2282 .

[0385] That is to say, the sleeve 560 is installed in the accommodating section 2281, and the stop section 2282 can limit the axial direction of the sleeve 560, so that the sleeve 560 can be closer to the side of the sleeve fixing structure 228 facing the output shaft 510, so that the output shaft 510 can be inserted into the sleeve 560.

[0386] In addition, the output shaft 510 can pass through the sleeve 560 and extend into the stop section 2282. The stop section 2282 can avoid position interference between the output shaft 510 and the hole wall of the sleeve fixing structure 228 to facilitate the rotation of the output shaft 510. Alternatively, the output shaft 510 can be inserted into the sleeve 560 but not extend out of the sleeve 560, that is, the output shaft 510 does not extend into the stop section 2282. By setting the stop section 2282, the weight of the duct member fixing portion 227 can be reduced, and the duct member fixing portion 227 can be more easily fixed on the first duct member 210 or the second duct member 220, and the duct member fixing portion 227 is not easy to shake, so that the free end of the output shaft 510 can be supported by the duct member fixing portion 227 and the sleeve 560.

[0387] In some embodiments of the present invention, Fig.58 As shown, the sleeve 560 is provided with a shaft hole 562 and a plurality of vibration-damping parts 565, the output shaft 510 is passed through the shaft hole 562, and the plurality of vibration-damping parts 565 are arranged at intervals along the circumference of the shaft hole 562. In this embodiment, the vibration-damping parts 565 can be configured as vibration-damping holes.

[0388] Among them, lubricating oil can be applied to the shaft hole 562 to facilitate the relative rotation of the output shaft 510 and the sleeve 560, and by providing multiple vibration-damping parts 565, not only the weight of the sleeve 560 can be reduced, but also the vibration transmission of the output shaft 510 can be reduced, that is, the amount of vibration transmitted from the output shaft 510 to the air duct fixing part 227 through the sleeve 560 can be smaller, and the sleeve 560 can buffer the vibration of the output shaft 510, further reducing the vibration and noise of the cabinet air conditioner, and providing a better user experience.

[0389] In some embodiments of the present invention, Fig.58 As shown, the sleeve 560 includes an inner sleeve 561 and an outer sleeve 563 .

[0390] The inner sleeve 561 is configured with an axial hole 562 , the outer sleeve 563 is disposed outside the inner sleeve 561 , and the outer sleeve 563 and the inner sleeve 561 are connected by a plurality of connecting ribs 564 , and the outer sleeve 563 , the inner sleeve 561 and adjacent connecting ribs 564 constitute a vibration damping portion 565 .

[0391] The plurality of connection ribs 564 may be arranged at intervals along the circumference of the shaft sleeve 560 , that is, the plurality of vibration damping parts 565 may be arranged at intervals along the circumference of the shaft sleeve 560 .

[0392] With such arrangement, a plurality of connecting ribs 564 can respectively connect the inner sleeve 561 and the outer sleeve 563, which can not only construct a vibration-damping portion 565 between adjacent connecting ribs 564 so that the sleeve 560 can weaken the vibration transmission of the output shaft 510, but also ensure that the connection strength between the inner sleeve 561 and the outer sleeve 563 is high, the overall structural strength of the sleeve 560 is higher, and the sleeve 560 is not easily deformed or damaged.

[0393] like Figure 52-Figure 58 As shown, the cabinet air conditioner according to some embodiments of the present invention includes a main body, which includes a casing 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 a motor 500.

[0394] The heat exchanger is arranged in the upper chamber, 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, 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, indoor air is sent to the indoor or outdoor through the second air duct 202, the first fan 300 is arranged in the second air duct 202 to send indoor air to the indoor or outdoor, the second fan 400 is arranged in the first air duct 201 to send outdoor air to the indoor, the motor 500 has a single output shaft 510, the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 to synchronously drive the first fan 300 and the second fan 400 to rotate.

[0395] One of the first air duct member 210 and the second air duct member 220 is provided with a shaft sleeve 560 , and one end of the output shaft 510 away from the motor 500 is rotatably inserted into the shaft sleeve 560 .

[0396] Specifically, the motor 500 can be arranged in the first air duct member 210, and the output shaft 510 of the motor 500 extends in the direction close to the second air duct member 220. In this case, the sleeve 560 can be arranged on the second air duct member 220, and the end of the output shaft 510 away from the motor 500 can be passed through the sleeve 560 on the second air duct member 220; or, the motor 500 can be arranged in the second air duct member 220, and the output shaft 510 of the motor 500 extends in the direction close to the first air duct member 210. In this case, the sleeve 560 can be arranged on the first air duct member 210, and the end of the output shaft 510 away from the motor 500 can be passed through the sleeve 560 on the first air duct member 210.

[0397] Thus, the end of the output shaft 510 away from the motor 500 can be rotatably connected to the sleeve 560, and the sleeve 560 can be used to support the free end of the output shaft 510 without affecting the rotation of the output shaft 510, so that the motor 500 can drive the second fan 400 and the first fan 300 to rotate through the output shaft 510, and after the sleeve 560 supports the free end of the output shaft 510, the rotation of the output shaft 510 can be more stable, that is, the vibration of the output shaft 510 during rotation can be smaller, and the output shaft 510 is not easy to shake, thereby greatly reducing the vibration of the output shaft 510 and the noise generated during vibration, the vibration and noise during the operation of the cabinet air conditioner are smaller, and the user experience is better.

[0398] According to some embodiments of the present invention, the cabinet air conditioner can enhance the support for the output shaft 510 of the motor 500, so that the rotation of the output shaft 510 is more stable, the vibration and the rotation noise are smaller, and the user experience is better.

[0399] In some embodiments of the present invention, Figure 53-Figure 55 As shown, one of the first duct member 210 and the second duct member 220 protrudes toward the output shaft 510 to form a duct member fixing portion 227 , a sleeve 560 is mounted on the duct member fixing portion 227 , and an end of the output shaft 510 away from the motor 500 is rotatably inserted into the sleeve 560 .

[0400] By making the air duct member fixing portion 227 protrude from the first air duct member 210 or the second air duct member 220, it is convenient to fix the sleeve 560 through the air duct member fixing portion 227, and the distance between the air duct member fixing portion 227 and the end of the output shaft 510 away from the motor 500 can be closer. After the sleeve 560 is installed in the air duct member fixing portion 227, it can be closer to the end of the output shaft 510 away from the motor 500, so that the end of the output shaft 510 away from the motor 500 can be inserted into the air duct member fixing portion 227, and the assembly is more convenient.

[0401] Other structures and operations of the cabinet air conditioner according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0402] The cabinet air conditioner in the present application performs a refrigeration cycle of the cabinet air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0403] The compressor compresses the 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 the heat is released to the surrounding environment through the condensation process.

[0404] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the cabinet air conditioner can adjust the temperature and humidity of the indoor space.
