[0069] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0070] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0071] The following describes a cabinet air conditioner according to some embodiments of the present disclosure with reference to FIG. 1 to FIG. 10 .

[0072] An air conditioner (hereafter, using a cabinet air conditioner as an example) consists of an indoor unit and an outdoor unit, connected by piping 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, outdoor heat exchanger, expansion valve, and indoor heat exchanger, connected in sequence, form a refrigerant circuit. The refrigerant circulates within this circuit, exchanging heat with the air through the outdoor and indoor heat exchangers, respectively, to achieve cooling or heating mode for the cabinet air conditioner.

[0073] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0074] The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported through the outdoor heat exchanger. For example, in the cooling mode of the cabinet air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to condense by dissipating heat to the outdoor air through the outdoor heat exchanger. In the heating mode of the cabinet air conditioner, the outdoor heat exchanger operates as an evaporator, causing the decompressed refrigerant to absorb heat from the outdoor air through the outdoor heat exchanger and evaporate.

[0075] In some embodiments of the present disclosure, 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.

[0076] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet of the outdoor unit and to 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.

[0077] The expansion valve is connected between the outdoor and indoor heat exchangers. The expansion valve's opening adjusts the refrigerant pressure flowing through the two heat exchangers, thereby regulating the refrigerant flow rate between the two. The refrigerant flow rate and pressure between the two heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening is adjustable to control the refrigerant flow rate and pressure through the expansion valve.

[0078] 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.

[0079] The indoor heat exchanger is configured to exchange heat between indoor air and the refrigerant flowing through it. For example, in the cooling mode of the cabinet air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat through the outdoor heat exchanger, to evaporate by absorbing heat from the indoor air through the indoor heat exchanger. In the heating mode of the cabinet air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat through the outdoor heat exchanger, to condense by dissipating heat to the indoor air through the indoor heat exchanger.

[0080] In some embodiments of the present disclosure, 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.

[0081] The indoor fan is configured to draw 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.

[0082] The cabinet air conditioner also includes a control device, which is primarily configured to control the operating frequency of the compressor, the opening of the expansion valve, and the speed of the outdoor fan and indoor fan. The control device is connected to the compressor, expansion valve, outdoor fan, and indoor fan via data cables to transmit communication information.

[0083] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor (Microprocessor), or 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-temporary computer-readable medium coupled to the control device.

[0084] As shown in FIG. 1 to FIG. 10 , the cabinet air conditioner according to some embodiments of the present disclosure includes a ventilation assembly 200 , which can simultaneously draw in fresh air and exhaust indoor air.

[0085] As shown in Figures 1 to 10, the cabinet air conditioner may further 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 may serve to accommodate and install other corresponding components of the cabinet air conditioner, and may be installed in the upper chamber and the lower chamber.

[0086] For example, the heat exchanger can be set 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 set in the lower chamber.

[0087] As shown in Figures 1 to 5, the ventilation assembly 200 is configured to deliver outdoor air into the room and deliver indoor air to the outside. In other words, the ventilation assembly 200 can simultaneously deliver fresh outdoor air into the room and exhaust dirty indoor air to the outside, thereby better refreshing the indoor air.

[0088] The ventilation assembly 200 includes a first duct member 210, through which outdoor fresh air enters the room. The first duct member 210 is formed with a first air inlet 211 and a first air outlet 212, with a first air duct 201 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. The second duct member 220 is formed with a second air inlet 221 and a second air outlet 222, with a second air duct 202 formed between the second air inlet 221 and the second air outlet 222.

[0089] The first air duct 210 is a fresh air duct, with the first air inlet 211 being a fresh air inlet configured to draw outdoor fresh air into the first duct member 210, and the first air outlet 212 being a fresh air outlet configured to discharge outdoor fresh air from the first duct member 210 for introduction into the interior of the room. The second air duct 220 is an exhaust duct, with the second air inlet 221 being an indoor air inlet configured to draw indoor air into the second duct member 220, and the second air outlet 222 being an indoor air outlet configured to discharge stale indoor air outdoors.

[0090] The first air duct member 210 is a structural member for air flow to pass through, and the first air duct member 210 is arranged in the lower chamber. In this way, the arrangement of the first air duct member 210 is more reasonable, and interference with heat exchange in the upper chamber can be avoided, and the first air duct member 210 can better play the role of air flow.

[0091] The first air inlet 211 primarily serves as an air intake, while the first air outlet 212 primarily serves as an air outlet. The first air duct 201 guides air circulation. Outdoor fresh air enters the first air duct member 210 through the first air inlet 211. The fresh air then flows along the first air duct 201 and into the room through the first air outlet 212, thereby introducing fresh outdoor air.

[0092] Similarly, the second air duct member 220 is also a structural member for air flow to pass through. The second air duct member 220 is set in the lower chamber. In this way, the setting of the second air duct member 220 is more reasonable, which can avoid interference with the heat exchange of the upper chamber. The second air duct member 220 can better play the role of air flow passing through.

[0093] The second air inlet 221 primarily serves as an air intake, while the second air outlet 222 primarily serves as an air outlet. The second air duct 202 guides air circulation. Indoor polluted air enters the second air duct member 220 through the second air inlet 221. The polluted air then flows along the second air duct 202 and is discharged outdoors through the second air outlet 222, thereby discharging the polluted air from the room.

[0094] As shown in Figure 3, the ventilation assembly 200 further includes a first fan 300, which is disposed within the second air duct 202 to deliver indoor air to the outside. This configuration is more efficient. When the first fan 300 is operating, it first draws dirty indoor air into the second air duct 202 and then exhausts the dirty indoor air from the second air duct 202 to the outside, thereby exhausting the dirty indoor air. The first fan 300 may be an exhaust fan.

[0095] As shown in Figure 3, the ventilation assembly 200 also includes a second fan 400, which is disposed within the first air duct 201 to deliver outdoor air into the room. This configuration is more rational. When the second fan 400 is operating, it first draws fresh outdoor air into the first air duct 201 and then releases the fresh outdoor air from the first air duct 201 into the room, thereby introducing fresh outdoor air. The second fan 400 can be a fresh air fan.

[0096] As shown in FIG3 and FIG6 , the ventilation assembly 200 further includes a motor 500 having a single output shaft 510 , to which the first fan 300 and the second fan 400 are transmission-connected to drive the first fan 300 and the second fan 400 to rotate synchronously.

[0097] The motor 500 primarily drives the air and has a single output shaft 510. In other words, the motor 500 outputs power only through the output shaft 510. The first fan 300 and the second fan 400 are connected to the output shaft 510. When the motor 500 is operating, the output shaft 510 simultaneously drives the first and second fans 300 and 400. This allows the first fan 300 to expel polluted air from the room while the second fan 400 draws in fresh air from the outside.

[0098] As shown in Figures 3, 7, and 8, the motor 500 is disposed in one of the first fan 300 and the second fan 400, and an accommodation portion 310 is formed in one of the first fan 300 and the second fan 400 to accommodate the motor 500. An escape portion 410 is formed in the other of the first fan 300 and the second fan 400 to avoid the accommodation portion 310, and the accommodation portion 310 is disposed corresponding to the escape portion 410.

[0099] For example, as shown in Figures 7 and 8, if the first fan 300 is provided with a housing portion 310, then the second fan 400 is provided with a relief portion 410, and the motor 500 can be disposed within the housing portion 310 of the first fan 300. In this way, the motor 500 can be disposed inside the first fan 300. Moreover, the relief portion 410 can avoid the housing portion 310. In other words, the housing portion 310 can be positioned within the relief portion 410. This can reduce the size of the relief portion 410 in the direction in which it fits with the housing portion 310, thereby reducing the volume of the ventilation assembly 200.

[0100] In addition, the avoidance portion 410 is disposed opposite to the accommodation portion 310, which can reduce the relative dimensions of the avoidance portion 410 and the accommodation portion 310, thereby reducing the volume of the ventilation assembly 200. The accommodation portion 310 can be a convex structure, and the avoidance portion 410 can be a concave structure.

[0101] Furthermore, one of the first fan 300 and the second fan 400 is provided with a first stop 320, and the other is provided with a second stop 420, and the first stop 320 and the second stop 420 cooperate with each other. When the motor 500 is in operation, the motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first stop 320 and the second stop 420 cooperate to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0102] It should be noted that the first and second stoppers 320 and 420 cooperate to prevent the second and first fans 400 and 300 from rotating circumferentially around the output shaft 510. This prevents relative rotation between the second and first fans 400 and 300, allowing them to rotate at the same frequency as the output shaft 510. Furthermore, the cooperation between the first and second stoppers 320 and 420 also ensures proper positioning of the second and first fans 400 and 300 during assembly.

[0103] Thus, even if the first and second fans 300 and 400 experience different wind resistances, the first and second stoppers 320 and 420 cooperate to allow the faster fan to drive the slower fan, while the faster fan is affected by the slower fan and its speed decreases. For example, if the second fan 400 experiences greater wind resistance and the first fan 300 experiences less wind resistance, the speed of the second fan 400 may be lower than that of the first fan 300. With the first and second stoppers 320 and 420 engaged, the first fan 300 can drive the second fan 400 to accelerate, while the speed of the first fan 300 is affected by the second fan 400 and its speed decreases. This allows the first and second fans 300 and 400 to maintain consistent speeds and rotate at the same frequency, reducing rotational noise and vibration of the first and second fans 300 and 400, thereby improving the performance of the air conditioner.

[0104] Thus, by providing the accommodation portion 310 on one of the first fan 300 and the second fan 400, and providing the avoidance portion 410 on the other, and disposing the motor 500 inside the first fan 300 or the second fan 400, while achieving simultaneous exhaust and intake of air into the room, the volume occupied by the ventilation assembly 200 can be reduced, thus lowering costs and improving the versatility of the cabinet air conditioner.

[0105] Furthermore, the accommodating 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. In other words, the accommodating portion 310 is configured to protrude toward the avoiding portion 410. Correspondingly, since the avoiding portion 410 is provided correspondingly to the accommodating portion 310, the avoiding portion 410 is configured to be recessed.

[0106] For example, the accommodating portion 310 is provided on the first fan 300, and the avoiding portion 410 is provided on the second fan 400, with the accommodating portion 310 protruding toward the second fan 400 along the axis of the first fan 300. This allows the accommodating portion 310 and the avoiding portion 410 to fit more closely together, allowing the motor 500 to be installed within the accommodating portion 310. This reduces the additional space occupied by the motor 500, thereby reducing the overall volume of the ventilation assembly 200.

[0107] In some embodiments of the present disclosure, as shown in Figure 7, the receiving portion 310 includes a first protrusion 311 and a second protrusion 312. The first protrusion 311 may have a cavity formed therein, while the second protrusion 312 mainly serves as a connection.

[0108] As shown in Figures 3, 7, and 8, the first protrusion 311 protrudes toward the avoidance portion 410, which allows the first protrusion 311 to better fit with 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 within the first protrusion 311. In other words, the motor 500 is at least partially disposed within the cavity formed within the first protrusion 311. This facilitates the coordination of the motor 500 with the first fan 300 or the second fan 400, and reduces the additional space occupied by the motor 500, thereby reducing the overall volume of the ventilation assembly 200.

[0109] As shown in Figures 3 and 7, the second protrusion 312 protrudes toward the avoidance portion 410 and is connected to the side of the first protrusion 311 adjacent to the avoidance portion 410. This prevents interference between the second protrusion 312 and the motor 500, while also reducing the relative dimensions of the avoidance portion 410 and the accommodating portion 310. The motor 500 is in transmission connection with the second protrusion 312, providing power to the second protrusion 312. In other words, the motor 500 can drive the second protrusion 312 to rotate, thereby driving the first fan 300 or the second fan 400 to rotate, thereby achieving exhaust or intake.

[0110] In some embodiments of the present disclosure, as shown in FIG7 , the cross-sectional area of ​​the first protrusion 311 gradually decreases toward the avoidance portion 410. This reduces the volume of the first protrusion 311, thereby lowering the manufacturing cost of the first protrusion 311 while ensuring that the cavity formed is sufficient to accommodate the motor 500. Furthermore, the inclined surface of the first protrusion 311 enhances the structural strength of the accommodating portion 310 to a certain extent.

[0111] In some embodiments of the present disclosure, as shown in Figures 3 and 8, the avoidance portion 410 includes a plurality of connecting bars 411 and a connecting plate 412. The plurality of connecting bars 411 extend in a direction away from the accommodating portion 310 and are close to each other. The connecting plates 412 are respectively connected to the plurality of connecting bars 411, and the motor 500 is also in driving connection with the connecting plates 412.

[0112] The connecting strips 411 primarily serve as a connection. Multiple connecting strips 411 extend away from the accommodating portion 310 and approach one another. In other words, the multiple connecting strips 411 have an inclined structure that converges toward the center. Thus, the inclined arrangement of the multiple connecting strips 411 corresponds to the structure of the accommodating portion 310, and the accommodating portion 310 can be positioned opposite the avoidance portion 410. Furthermore, the multiple connecting strips 411 extend away from the accommodating portion 310 and approach one another. In this way, the accommodating portion 310 can fit between the multiple connecting strips 411, thereby forming a fit between the avoidance portion 410 and the accommodating portion 310, reducing the size of the avoidance portion 410 in the relative direction to the accommodating portion 310, and thereby reducing the volume of the first fan 300 and the second fan 400 after they are fitted together.

[0113] The connecting plate 412 primarily serves as a connection, and is connected to the plurality of connecting strips 411. This allows the connecting plate 412 to be fixed, making its arrangement more secure and stable. Furthermore, because the motor 500 is also in transmission connection with the connecting plate 412, the motor 500 can simultaneously drive the connecting plate 412 to rotate while simultaneously driving the second protrusion 312 to rotate. In other words, 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, achieving simultaneous indoor air intake and exhaust.

[0114] In some embodiments of the present disclosure, as shown in Figures 1 to 5, the cabinet air conditioner further includes a first duct housing 223, a second duct housing 224, and a third duct housing 213. The first duct housing 223 constitutes the first portion of the second duct member 220, and the first duct housing 223 constitutes the first portion of the first duct member 210. The second duct housing 224 constitutes the second portion of the second duct member 220, and the third duct housing 213 constitutes the second portion of the first duct member 210.

[0115] 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.

[0116] The first duct housing 223 constitutes the first portion of the second duct member 220, and the second duct housing 224 constitutes the second portion of the second duct member 220. In other words, the first duct housing 223 and the second duct housing 224 form a complete second duct member 220, allowing indoor polluted air to be exhausted within the second duct member 220. Of course, the first fan 300 is disposed within the second duct 202 within the second duct member 220. Thus, the first fan 300 can draw polluted air from the room into the second duct member 220 through the second air inlet 221, and then exhaust the polluted air from the room through the second air outlet 222, thereby exhausting the indoor air.

[0117] The first duct housing 223 constitutes the first portion of the first duct member 210, and the third duct housing 213 constitutes the second portion of the first duct member 210. In other words, the first duct housing 223 and the third duct housing 213 form the complete first duct member 210. In this way, fresh outdoor air can enter the first duct member 210 through the first air inlet 211. Of course, the second fan 400 is disposed within the fresh air passage of the first duct member 210. In this way, the second fan 400 can draw fresh outdoor air into the first duct member 210 through the first air inlet 211, and then release the fresh outdoor air from the first duct member 210 into the room through the first air outlet 212, thereby releasing fresh air into the room.

[0118] In some embodiments of the present disclosure, as shown in Figures 5 and 6, the first air duct housing 223 is provided with a limiting portion 2231. The limiting portion 2231 can be configured as a protrusion. 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 housing 223, so that a matching structure can be formed on the first air duct housing 223, so that the first air duct housing 223 can better match with the second air duct housing 224 and the third air duct housing 213.

[0119] The limiting portion 2231 is located between the accommodating portion 310 and the escape portion 410, and the limiting portion 2231 protrudes toward the escape portion 410. In other words, the limiting portion 2231 and the accommodating portion 310 protrude in the same direction. This allows the accommodating portion 310 to better fit within the limiting portion 2231, while the limiting portion 2231 also better fits within the escape portion 410. This reduces the combined volume of the first, second, and third air duct housings 223, 224, and 213, and consequently, the overall volume of the ventilation assembly 200.

[0120] Furthermore, as shown in Figures 5 and 6 , 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 may be a threaded segment. 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.

[0121] The fastener 520 primarily serves as a fixation mechanism, while the output shaft 510 primarily transmits torque, and the output shaft securing portion 512 primarily serves as a fixation mechanism. The output shaft 510 passes through the first and second fans 300, 400, and the fastener 520 is secured to the output shaft securing portion 512. This allows the fastener 520 to limit the position of the first and second fans 300, 400 along the axis of the output shaft 510 when the motor 500 simultaneously drives the first and second fans 300, 400, thereby ensuring more stable operation of the first and second fans 300, 400.

[0122] For example, as shown in Figures 5 and 6, fastener 520 is a nut, and output shaft fixing portion 512 is a threaded segment with external threads on its surface, with the nut mating with the external threads. This simplifies assembly between fastener 520 and output shaft fixing portion 512, and provides a firm and stable connection between the nut and the external threads, with high connection strength. Furthermore, the nut and external threads have a simple structure, making them easy to process and install.

[0123] 6 , 9 , and 10 , the cabinet air conditioner further includes a motor bracket 530 and a motor pressure plate 540. The motor bracket 530 is fixed to the first duct member 210 or the second duct member 220, the motor pressure plate 540 is fixedly connected to the motor bracket 530, and the motor 500 is sandwiched between the motor bracket 530 and the motor pressure plate 540.

[0124] The motor bracket 530 primarily serves as a mounting mechanism, while the motor pressure plate 540 primarily serves as a mounting and positioning mechanism. Fixing the motor bracket 530 to the first duct member 210 or the second duct member 220 secures the motor bracket 530, making its placement more secure and stable. The motor pressure plate 540 is fixedly connected to the motor bracket 530, thereby securing the motor pressure plate 540 and sandwiching the motor 500 between the motor bracket 530 and the motor pressure plate 540. Thus, the motor bracket 530 and the motor pressure plate 540 can be used to position and secure the motor 500, allowing the motor 500 to operate more stably.

[0125] 9 and 10 , the motor bracket 530 is provided with a first mounting portion 531, and the motor pressure plate 540 is provided with a second mounting portion 541. The first mounting portion 531 and the second mounting portion 541 are correspondingly mounted and connected. The motor bracket 530 is provided with a first positioning portion 532, and the motor pressure plate 540 is provided with a second positioning portion 542. The first positioning portion 532 and the second positioning portion 542 are correspondingly positioned and matched.

[0126] The first mounting portion 531 and the second mounting portion 541 both serve as mounting elements, and the first mounting portion 531 and the second mounting portion 541 are correspondingly connected. Thus, 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, thereby enabling the motor 500 to operate better.

[0127] Both the first positioning portion 532 and the second positioning portion 542 can function as positioning members, and the first positioning portion 532 and the second positioning portion 542 cooperate in positioning. Thus, when the motor bracket 530 is mated with the motor pressure plate 540, the first positioning portion 532 and the second positioning portion 542 can first be used to position the motor bracket 530 and the motor pressure plate 540. This improves the speed and accuracy of assembly between the motor bracket 530 and the motor pressure plate 540, and enhances the assembly quality of the motor bracket 530 and the motor pressure plate 540.

[0128] The following describes a cabinet air conditioner according to some embodiments of the present disclosure with reference to FIG. 11 to FIG. 21 .

[0129] 11 to 21 , a cabinet air conditioner according to some embodiments of the present disclosure includes: a housing 100, a heat exchange fan, a first duct member 210, a second duct member 220, a motor 500, a first duct 201, a second duct 202, a purification duct, a communication port 230, a first baffle 240, and a second baffle 250. The first duct member 210 may be a fresh air duct member, the second duct member 220 may be an exhaust air duct member, and the motor 500 may be a single-shaft motor.

[0130] The interior of the cabinet 100 is formed with an upper chamber and a lower chamber located below the upper chamber. The lower chamber is provided with a third air inlet 110 and a third air outlet 120. A second air duct 202 is defined within the cabinet air conditioner from the third air inlet 110 to the third air outlet 120. The third air inlet 110 serves as the indoor air intake, while the third air outlet 120 serves as the indoor air outlet. The third air inlet 110 corresponds to the second air inlet 221, allowing indoor air to be drawn into the cabinet through the third air inlet 110 and then into the second duct member 220 through the second air inlet 221. The third air outlet 120 corresponds to the second air outlet 222, allowing contaminated indoor air to be discharged outdoors through the second air outlet 222 and the third air outlet 120, respectively.

[0131] 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 between the fifth air inlet 160 and the fifth air outlet 170 in the cabinet air conditioner, wherein the fifth air inlet 160 is the fresh air inlet, and the fifth air outlet 170 is the 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 210 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.

[0132] Furthermore, the lower chamber is provided with a fourth air inlet 130 and a fourth air outlet 140. A purified air duct is defined within the cabinet air conditioner from the fourth air inlet 130 to the fourth air outlet 140. The fourth air inlet 130 is the purified air inlet, and the fourth air outlet 140 is the purified air outlet. The fourth air inlet 130 corresponds to the second air inlet 221, so that indoor air is introduced into the casing through the fourth air inlet 130 and then into the second air duct member 220 through the second air inlet 221. The purified indoor air is then discharged back into the room through the fourth air outlet 140.

[0133] For example, the interior of the cabinet air conditioner is divided into two parts, an upper chamber formed in the upper part and a lower chamber formed in the lower part. The upper chamber and the lower chamber are connected by an air supply duct 150. Indoor air can enter the cabinet air conditioner through the third air inlet 110 provided on the lower chamber, pass through the second air duct 202, and be discharged outdoors through the third air outlet 120. Fresh air from outdoors can enter the cabinet air conditioner through the fifth air inlet 160 provided on the lower chamber, pass through the first air duct 201, and be blown into the room through the fifth air outlet 170. This allows indoor and outdoor air to circulate, reducing the accumulation of pollutants, bacteria, viruses, and other harmful substances in the indoor air, which can lead to a decrease in indoor air quality and be detrimental to user health.

[0134] Furthermore, the lower chamber is provided with a fourth air inlet 130 and a fourth air outlet 140. When the user activates the indoor air circulation and purification mode, indoor air can enter the cabinet air conditioner through the fourth air inlet 130, pass through the purification duct, and then be discharged into the room through the fourth air outlet 140, thereby filtering and purifying the indoor air and improving the indoor air quality. It should be noted that when the air circulation and purification mode is activated, all indoor air enters the purification duct and cannot be discharged to the outside through the second air duct 202. At this time, the second air duct 202 is in an empty state.

[0135] 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 into 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 achieve the regulation of the indoor temperature.

[0136] 11 to 13 , the cabinet air conditioner further includes a first duct member 210 disposed within the lower chamber. The first duct member 210 is configured to draw outdoor air from the outside through a first air duct 201 and blow the air 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 disposed in the fresh air cavity 214.

[0137] That is, the first duct member 210 is disposed within the lower chamber, and a fresh air chamber 214 is formed within the first duct member 210. The second fan 400 is disposed within the fresh air chamber 214. When the second fan 400 is in operation, fresh air from outside is drawn in through the fifth air inlet 160, discharged through the fifth air outlet 170 on the first duct member 210, and driven by the heat exchange blower, enters the upper chamber through the air supply duct 150. After heat exchange with the heat exchanger in the upper chamber, the heat exchange airflow is formed, which is then blown into the room by the heat exchange blower. The introduction of fresh air through the first duct member 210 and its blowing into the room improves indoor air quality, giving users a more natural experience and enhancing the performance of the air conditioner.

[0138] The cabinet air conditioner further includes a second duct member 220 disposed within the lower chamber and spaced apart from the first duct member 210. The second duct member 220 is configured to draw indoor air from the room and discharge it outdoors through the second air duct 202. An exhaust cavity 225 is formed in the second duct member 220, and a first fan 300 is disposed in the exhaust cavity 225.

[0139] Specifically, the second duct member 220 is disposed within the lower chamber, spaced apart from the first duct member 210 and located on a side of the first duct member 210 away from the third air outlet 120. An exhaust cavity 225 is formed within the second duct member 220, and the first fan 300 is disposed within the exhaust cavity 225. When the first fan 300 is in operation, indoor air is drawn in through the third air inlet 110, passes through the second air duct 202, and is then exhausted through the third air outlet 120. This allows accumulated dirty air to be discharged outdoors, improving indoor air quality.

[0140] The cabinet air conditioner also includes a motor 500 having a single output shaft 510, to which the first fan 300 and the second fan 400 are connected. When the motor 500 is in operation, it drives the first fan 300 and the second fan 400 to rotate simultaneously. Thus, the motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second duct member 220 cooperates with the first duct member 210 to draw in fresh outdoor air while expelling contaminated indoor air, maintaining good indoor air circulation and improving indoor air quality.

[0141] The connecting port 230 is used to connect the first air duct 201 and the exhaust air duct (second air duct 202). Since 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 cabinet air conditioner in the related art, the cabinet air conditioner in some embodiments of the present disclosure makes full use of 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.

[0142] The cabinet air conditioner further includes a first baffle 240 and a second baffle 250. The first baffle 240 is rotatably disposed in the second air duct 202 or the first air duct 201 to open or close the communication port 230. The second baffle 250 is rotatably 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.

[0143] 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 configured to open or close the communication port 230 to control the communication between the first air duct 201 and the second air duct 202.

[0144] The second baffle 250 can rotate within 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 in the purification air duct to block the air flow between the third air inlet 110 and the fourth air outlet 140, allowing the third air inlet 110 to communicate with the third air outlet 120. In this case, the exhaust mode operates normally. The second baffle 250 can also be located in the second air duct 202 to block the air flow between the third air inlet 110 and the third air outlet 120, allowing the third air inlet 110 to communicate with the fourth air outlet 140, and the indoor air circulation purification mode is activated.

[0145] 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.

[0146] In some embodiments of the present disclosure, as shown in Figures 12 and 13, 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 communication port 230. When the first baffle 240 is in the second position, the first baffle 240 opens the communication port 230, allowing the first duct member 210 to draw outdoor air from the outside through the first duct 201 and the second duct 202.

[0147] For example, when the first baffle 240 is in the first position, the first baffle 240 can block the communication port 230. At this time, air cannot circulate in the first air duct 201 and the second air duct 202, and the second air duct 202 and the first air duct 201 respectively perform the functions of exhausting indoor polluted air and inhaling outdoor fresh air.

[0148] For another example, after rotating the first baffle 240 clockwise by a certain angle, the first baffle 240 is in the second position. At this time, the first baffle 240 does not block the communication port 230, allowing air to circulate in the first air duct 201 and the second air duct 202. The second air duct 202 can be used as the first air duct 201. The first air duct 201 and the second air duct 202 simultaneously introduce fresh air, thereby increasing the amount of fresh air, bringing more fresh air into the room, and improving the indoor air quality.

[0149] When the cabinet air conditioner is not in the indoor air circulation purification mode, the first baffle 240 can be rotated counterclockwise by an angle so that the first baffle 240 returns to the first position to block the connecting port 230, so that 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.

[0150] In some embodiments of the present disclosure, as shown in Figures 12 and 13, when the first baffle 240 is in the first position, the orthographic projection of the first baffle 240 on the horizontal plane covers the orthographic projection of the connecting opening 230 on the horizontal plane. In other words, the area of ​​the first baffle 240 is larger than the area of ​​the connecting opening 230, and the orthographic projection of the first baffle 240 on the horizontal plane can cover the orthographic projection of the connecting opening 230 on the horizontal plane. In this way, only when the first baffle 240 is in the first position can it effectively block the connecting opening 230, preventing air from overflowing from the connecting opening 230 into the second air duct 202 or the first air duct 201 when the second air duct 202 discharges indoor air or the first air duct 201 inhales outdoor air, causing the indoor air to mix and detrimental to improving the indoor air quality. The horizontal plane can be the plane where the first baffle 240 is located at the connecting opening 230.

[0151] In some embodiments of the present disclosure, as shown in Figures 12 and 13, 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 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 third air inlet 110 and the fourth air outlet 140, and connects the third air inlet 110 and the third air outlet 120.

[0152] For example, when second baffle 250 is in the third position, it disconnects third air inlet 110 from third air outlet 120. Due to the obstruction of second baffle 250, indoor air drawn from second duct member 220 cannot be discharged outdoors through second duct 202 and can only be delivered indoors. In this case, the cabinet air conditioner is in indoor air circulation and purification mode, and second duct 202 is idle. At this time, first baffle 240 can be in the second position, connecting port 230 to first duct 201 and second duct 202. First duct member 210 can simultaneously draw in outdoor fresh air from both first duct 201 and second duct 202, increasing the amount of fresh air indoors and significantly improving the air quality of the indoor living environment.

[0153] For another example, when the second baffle 250 is in the fourth position, the second baffle 250 rotates counterclockwise from the third position by an angle. This connects the third air inlet 110 and the third air outlet 120. At this point, the first baffle 240 can be in the first position, shielding the connecting port 230. The second air duct 202 is separated from the first air duct 201. Air drawn from the room by the second air duct member 220 is discharged outdoors through the third air outlet 120 and the second air duct 202, discharging accumulated indoor air. This maintains indoor air circulation and improves indoor air quality.

[0154] In some embodiments of the present disclosure, as shown in Figures 14 and 15 , the second baffle 250 and the first baffle 240 are integrally formed. Furthermore, the junction of the second baffle 250 and the first baffle 240 forms a pivot 241 between the first and second baffles 240, 250, enabling the first and second baffles 240, 250 to rotate about the pivot 241. The cabinet air conditioner further includes a first driving member that is in transmission engagement with the pivot 241. For example, the first and second baffles 240, 250 are provided with a pivot 241 between them, and the cabinet air conditioner is provided with the first driving member that is in transmission engagement with the pivot 241. In other words, the first driving member can drive the first and second baffles 240, 250 to rotate about the pivot 241. The first driving member can be a motor 500. Furthermore, the first and second baffles 240, 250 are integrally formed, and the first and second baffles 240, 250 can rotate within a range of degrees.

[0155] Thus, when the first baffle 240 is in the first position, the second baffle 250 is in the fourth position. At this point, the first baffle 240 blocks the communication port 230 between the second air duct 202 and the first air duct 201, and the third air inlet 110 is connected to the third air outlet 120. At this point, the second air duct 202 is used only to cooperate with the second air duct member 220 to exhaust indoor air, maintaining indoor air circulation.

[0156] When the first baffle 240 is in the second position, the second baffle 250 is in the third position. At this point, the connecting opening 230 between the second air duct 202 and the first air duct 201 is open, 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 instead output to the upper chamber. After heat exchange in the heat exchanger, it is output to the indoor room, thus forming an indoor air circulation purification mode. Furthermore, driven by the first air duct member 210, the second air duct 202 connects with the first air duct 201 to jointly draw fresh air from the outside. This allows the second air duct 202 to introduce fresh air while simultaneously achieving the indoor air circulation purification mode. This prevents the second air duct 202 from being idle, increases the amount of fresh air, maintains fresh indoor air, and significantly improves the air quality of the indoor living environment.

[0157] In some embodiments of the present disclosure, as shown in FIG. 15 , a clearance space 251 is formed between the first baffle 240 and the second baffle 250. When the second baffle 250 is in the third position and the first baffle 240 is in the second position, the orthographic projection of the clearance space 251 on the horizontal plane overlaps the orthographic projection of the communication port 230 on the horizontal plane, so that the clearance space 251 is connected to the communication port 230. Because the first baffle 240 and the second baffle 250 are an integrally formed structure, the clearance space 251 is formed between the first baffle 240 and the second baffle 250 to ensure that the communication port 230 is not blocked when the first baffle 240 rotates to the second position and the second baffle 250 rotates to the third position. Moreover, when the second baffle 250 is in the third position, the orthographic projection of the clearance space 251 on the horizontal plane overlaps the orthographic projection of the communication port 230 on the horizontal plane.

[0158] 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.

[0159] The cabinet air conditioner further includes a second driving member and a third driving member. The second driving member is drivingly connected to the first baffle 240 to drive the first baffle 240 to rotate between the first position and the second position. The third driving member is drivingly connected to the second baffle 250 to drive the second baffle 250 to rotate between the third position and the fourth position. In other words, the first baffle 240 and the second baffle 250 can also be driven by different driving members. The cabinet air conditioner further includes a second driving member and a third driving member, wherein the second driving member is drivingly connected to the first baffle 240 and the third driving member is drivingly connected to 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.

[0160] In this way, when the first baffle 240 is in the first position, the second baffle 250 can be in the third position. In this case, the connecting port 230 is blocked 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, where it is heated in the heat exchanger and then output to the room. The second duct member 220 only operates in the indoor air circulation and purification mode, and the second air duct 202 is idle. When the first baffle 240 is in the first position, the second baffle 250 can also be in the fourth position. In this case, the first baffle 240 blocks 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. In this case, the second air duct 202 is only used to cooperate with the second duct member 220 to exhaust indoor air, maintaining indoor air circulation.

[0161] Furthermore, when the first baffle 240 is in the second position, the second baffle 250 can be in the third position. In this case, the connecting opening 230 between the second air duct 202 and the first air duct 201 is open, 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 instead output to the upper chamber. After heat exchange in the heat exchanger, it is output to the indoor room, forming an indoor air circulation purification mode. Furthermore, driven by the first air duct member 210, the second air duct 202 connects with the first air duct 201 to jointly draw fresh air from the outside. This allows the second air duct 202 to introduce fresh air while achieving the indoor air circulation purification mode, preventing the second air duct 202 from being idle. This also increases the amount of fresh air, maintains fresh indoor air, and significantly improves the air quality of the indoor living environment.

[0162] 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. In this way, 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.

[0163] In some embodiments of the present disclosure, as shown in FIG. 14 , the second duct member 220 is provided with a second air inlet 221, which is disposed opposite the third air inlet 110. Furthermore, the cabinet air conditioner further includes an exhaust filter 226, which is fixed to the inner side of the casing 100 and sandwiched between the third air inlet 110 and the second air inlet 221. Driven by the second duct member 220, indoor air enters the second air duct 202 through the second and third air inlets 221, 110. By sandwiching the exhaust filter 226 between the third and second air inlets 110, 221, the indoor air drawn in by the second duct member 220 is filtered. The air filtered by the exhaust filter 226 then enters the room through the purified air duct and participates in the indoor air circulation, thereby purifying the indoor air and improving air quality. The exhaust filter 226 may be a filter.

[0164] In some embodiments of the present disclosure, as shown in FIG. 14 , the cabinet air conditioner further includes a fresh air filter 215 disposed within the first air duct 201 and opposite the fifth air inlet 160. As the second fan 400 operates, fresh air drawn in from outside can enter the first air duct 201 through the fifth air inlet 160. The fresh air filter 215 disposed within the first air duct 201 and opposite the fifth air inlet 160 improves the cleanliness of the air blown out by the air conditioner after being filtered by the fresh air filter 215, thereby improving the living environment. The fresh air filter 215 may be a filter.

[0165] As shown in Figures 14 and 16, the cabinet air conditioner further includes an opening and closing member 161, which is rotatably disposed at the fifth air inlet 160. The opening and closing member 161 has a fifth position and a sixth position. When the opening and closing member 161 is in the fifth position, the opening and closing member 161 closes the fifth air inlet 160. When the opening and closing member 161 is in the sixth position, the opening and closing member 161 opens the fifth air inlet 160.

[0166] For example, the opening and closing member 161 is located at the fifth air inlet 160 and is configured to control the opening and closing of the first air duct 201. When the first air duct 210 stops operating, the opening and closing member 161 is in the fifth position, which closes the fifth air inlet 160. This effectively prevents outdoor air from backflowing into the first air duct 210 and generating noise, thereby providing a good quiet effect for the indoor space. When the opening and closing member 161 is in the sixth position, the opening and closing member 161 opens the fifth air inlet 160, allowing outdoor fresh air to enter the housing 100 through the fifth air inlet 160, providing fresh air for the indoor space. The opening and closing member 161 can be controlled by the motor 500.

[0167] 11 to 21 , the cabinet air conditioner of some embodiments of the present disclosure includes a casing 100 , a heat exchange fan, a first duct member 210 , a second duct member 220 , a motor 500 , a first duct 201 , a second duct 202 , a purification duct, a connecting port 230 , a first baffle 240 , and a second baffle 250 .

[0168] The interior of the housing 100 is formed with an upper chamber and a lower chamber located 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 also provided with a fifth air inlet 160 and a fifth air outlet 170. The lower chamber is also provided with a fourth air inlet 130 and a fourth air outlet 140. A heat exchange fan is installed in the upper chamber. Furthermore, a first air duct 201 is defined within the cabinet air conditioner from the fifth air inlet 160 to the fifth air outlet 170, a second air duct 202 is defined from the third air inlet 110 to the third air outlet 120, and a purification air duct is defined from the fourth air inlet 130 to the fourth air outlet 140.

[0169] For example, the interior of a cabinet air conditioner is divided into two parts, an upper chamber formed in the upper part and a lower chamber formed in the lower part. The upper and lower chambers are connected by an air supply duct 150. Indoor air can enter the cabinet air conditioner through the third air inlet 110 provided on the lower chamber, pass through the second air duct 202, and be discharged outdoors through the third air outlet 120. Fresh air from the outside can enter the cabinet air conditioner through the fifth air inlet 160 provided on the lower chamber, pass through the first air duct 201, and be blown into the room through the fifth air outlet 170. This allows for indoor and outdoor air circulation, reducing the accumulation of harmful substances such as pollutants, bacteria, and viruses in the indoor air, which can lead to a decrease in indoor air quality.

[0170] Furthermore, the lower chamber is provided with a fourth air inlet and a fourth air outlet. When the user activates the indoor air circulation and purification mode, indoor air can enter the cabinet air conditioner through the fourth air inlet, pass through the purification duct, and then be discharged into the room through the fourth air outlet, thereby filtering and purifying the indoor air and improving the indoor air quality. It should be noted that when the air circulation and purification mode is activated, all indoor air enters the purification duct and cannot be discharged to the outside through the second air duct 202. At this time, the second air duct 202 is in an empty state.

[0171] In addition, a heat exchange fan is disposed in the upper chamber. When the cabinet air conditioner is in operation, the heat exchange fan drives indoor air into the interior of the housing 100. The indoor air exchanges heat with the heat exchanger to form a heat exchange airflow. Driven by the heat exchange fan, the heat exchange airflow is blown into the room to regulate the indoor temperature.

[0172] 12 and 13 , the cabinet air conditioner further includes a first duct member 210 disposed within the lower chamber. The first duct member 210 is configured to draw outdoor air from the outside through a first air duct 201 and blow the air 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 disposed in the fresh air cavity 214.

[0173] That is, the first duct member 210 is disposed in the lower chamber, a fresh air chamber 214 is formed inside the first duct member 210, and the second fan 400 is disposed in the fresh air chamber 214. When the second fan 400 is in operation, fresh air from outside can be introduced through the fifth air inlet 160, discharged through the fifth air outlet 170 on the first duct member 210, and driven by the heat exchange fan to enter the upper chamber from the air supply duct 150. After heat exchange with the heat exchanger in the upper chamber, the heat exchange airflow is formed. The heat exchange airflow is blown into the room under the drive of the heat exchange fan. The fresh air is introduced through the first duct member 210 and blown into the room, thereby improving the indoor air quality, giving the user a more natural experience, and enhancing the use effect of the air conditioner.

[0174] The cabinet air conditioner further includes a second duct member 220 disposed within the lower chamber and spaced apart from the first duct member 210. The second duct member 220 is configured to draw indoor air from the room and discharge it to the outside through the second duct 202. An exhaust cavity 225 is formed in the second duct member 220, and a first fan 300 is disposed in the exhaust cavity 225.

[0175] That is, the second duct member 220 is disposed within the lower chamber, spaced apart from the first duct member 210 and located on a side of the first duct member 210 away from the third air outlet 120. A new exhaust cavity 225 is formed within the second duct member 220, and the first fan 300 is disposed within the exhaust cavity 225. When the first fan 300 is in operation, it draws indoor air in through the third air inlet 110, passes through the second air duct 202, and is then discharged through the third air outlet 120. This allows accumulated dirty air to be discharged outdoors, thereby improving indoor air quality.

[0176] The cabinet air conditioner also includes a motor 500 having a single output shaft 510, to which the first fan 300 and the second fan 400 are connected. When the motor 500 is in operation, it drives the first fan 300 and the second fan 400 to rotate simultaneously. Thus, the motor 500 drives the first fan 300 and the second fan 400 to rotate simultaneously, and the second duct member 220 cooperates with the first duct member 210 to draw in fresh outdoor air while expelling contaminated indoor air, maintaining good indoor air circulation and improving indoor air quality.

[0177] The connecting port 230 is used to connect the first air duct 201 and the exhaust air duct (second air duct 202). Since 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 cabinet air conditioners in the related art, the cabinet air conditioners in some embodiments of the present disclosure make full use of 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.

[0178] The cabinet air conditioner further includes a first baffle 240 and a second baffle 250. The first baffle 240 is rotatably disposed at the communication port 230 to open or close the communication port 230. The second baffle 250 is 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.

[0179] 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 configured to open or close the communication port 230 to control the communication between the first air duct 201 and the second air duct 202 .

[0180] The second baffle 250 can rotate within 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 in the purification air duct to block the air flow between the third air inlet 110 and the fourth air outlet, allowing the third air inlet 110 to communicate with the third air outlet 120. At this time, the exhaust mode operates normally. The second baffle 250 can also be located in the second air duct 202 to block the air flow between the third air inlet 110 and the third air outlet 120, allowing the third air inlet 110 to communicate with the fourth air outlet, at which time the indoor air circulation purification mode is activated.

[0181] Thus, by providing the connecting port 230, the first baffle 240, and the second baffle 250, the first baffle 240 and the connecting port 230 cooperate to control the connection and disconnection of the first air duct 201 and the second air duct 202. The second baffle 250 can control the switching between the exhaust mode and the indoor air circulation and purification mode. When the indoor air circulation and purification mode is implemented, 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.

[0182] The following describes a cabinet air conditioner according to some embodiments of the present disclosure with reference to the accompanying drawings.

[0183] As shown in FIG. 22 to FIG. 29 , the cabinet air conditioner according to some embodiments of the present disclosure includes a casing 100 , a heat exchanger, a heat exchange fan, and a ventilation assembly 200 .

[0184] As shown in Figure 22, the housing 100 has an upper chamber and a lower chamber. A heat exchanger is located in the upper chamber, and a heat exchange blower is configured to deliver air that has exchanged heat with the heat exchanger into the room. A ventilation assembly 200 is located in the lower chamber and is configured to deliver outdoor air into the room, and indoor air to either the indoor or outdoor space.

[0185] The ventilation assembly 200 includes a first duct member 210 , a second duct member 220 , a first fan 300 , a second fan 400 , a motor 500 , a filter unit, and a mounting bracket 600 .

[0186] A first duct member 210 is disposed in the lower chamber. A first duct member 210 defines a first duct 201, through which fresh outdoor air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 220 defines a second duct 202, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed in the second duct 202 to deliver indoor air to the indoors or outdoors, while a second fan 400 is disposed in the first duct 201 to deliver outdoor air indoors. A motor 500 has a single output shaft 510. The first and second fans 300 and 400 are transmission-connected to the output shaft 510. The motor 500 drives the first and second fans 300 and 400 to rotate synchronously via the output shaft 510. An exhaust filter 226 is disposed on the air inlet side of the second duct 202 to purify the indoor air entering the second duct 202.

[0187] As shown in Figures 24 to 29, 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, and the motor mounting portion 620 is connected to the bracket body 610 and 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.

[0188] 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 , which extends from one side of the motor 500 , and the first fan 300 and the second fan 400 are transmission-connected to the output shaft 510 , and the motor 500 drives the first fan 300 and the second fan 400 to rotate synchronously via the output shaft 510 .

[0189] In some embodiments of the cabinet air conditioner disclosed herein, the housing 100 is provided with an upper chamber and a lower chamber, a heat exchanger is provided in the upper chamber, and a heat exchange blower is configured to deliver air after heat exchange with the heat exchanger into the room. The ventilation component 200 is provided in the lower chamber, and the ventilation component 200 is configured to deliver outdoor air into the room, and to deliver indoor air to the room or the room. 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, thereby discharging the relatively dirty indoor air to the outside, so as to quickly purify the indoor air after the introduction of outdoor air. Alternatively, the ventilation component 200 can draw indoor air into the housing 100, exchange heat with the heat exchanger, and then discharge it into the room, thereby quickly achieving indoor cooling or heating.

[0190] Furthermore, a first duct member 210 is disposed in the lower chamber. A first duct member 201 is formed within the first duct member 210, through which outdoor fresh air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 202 is formed within the second duct member 220, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed within the second duct member 202 to deliver indoor air indoors or outdoors, while a second fan 400 is disposed within the first duct member 201 to deliver outdoor air indoors. In this way, the first duct member 210 can direct the outdoor fresh air, while the second duct member 220 can direct the indoor air, thereby separating the flow of outdoor fresh air and indoor air, preventing interference between the outdoor and indoor air flows and ensuring smoother airflow within the cabinet air conditioner.

[0191] Furthermore, the motor 500 has a single output shaft 510, to which the first fan 300 and the second fan 400 are transmission-connected. The motor 500, via the output shaft 510, synchronously drives the first fan 300 and the second fan 400 to rotate. This allows the first fan 300 and the second fan 400 to share a single motor 500, thereby reducing the number of motors 500, thereby reducing the number of components in the cabinet air conditioner, facilitating assembly, and reducing the space occupied by the motor 500, thereby reducing the volume of the ventilation assembly 200. Furthermore, the exhaust filter 226 is disposed on the air inlet side of the second air duct 202. This allows the exhaust filter 226 to purify the indoor air entering the second air duct 202, thereby improving the quality of the air entering the cabinet air conditioner. This improves the quality of the air discharged by the air conditioner and prevents dust and impurities from entering the housing 100.

[0192] 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 226 is mounted on the filter mounting portion 630 .

[0193] In other words, the mounting bracket 600 of some embodiments of the present disclosure can be used to simultaneously mount the motor 500 and the exhaust filter 226. In other words, the motor 500 and the exhaust filter 226 can be mounted on a single bracket. This reduces the number of brackets, making the mounting bracket 600 more integrated, more convenient, and faster to assemble, thereby improving assembly efficiency.

[0194] Moreover, it can be understood that compared with the related art in which two brackets are set to fix the motor 500 and the exhaust filter part 226 respectively, the cabinet air conditioner of some embodiments of the present disclosure can reduce one bracket, thereby saving a set of molds for producing the bracket, which is conducive to reducing the production cost of the installation bracket 600.

[0195] Furthermore, by connecting the bracket body 610 to the second duct member 220, the motor mounting portion 620 is connected to the bracket body 610 and extends into the second duct member 220, allowing the filter mounting portion 630 to be located outside the second duct member 220. Thus, after the motor 500 is mounted on the motor mounting portion 620, it can extend into the second duct member 220, allowing the motor 500 to be closer to the first fan 300 and the second fan 400, thereby facilitating transmission connection between the output shaft 510 of the motor 500 and the first fan 300 and the second fan 400, respectively. Furthermore, after the exhaust filter 226 is mounted on the filter mounting portion 630, it can be located outside the second duct member 220. This allows indoor air entering the second duct member 220 to be filtered before entering the second duct member 220, more effectively preventing dust and impurities from entering the second duct member 220, thereby keeping the interior of the second duct member 220 clean and improving the air quality of the cabinet air conditioner.

[0196] In this way, the cabinet air conditioner according to some embodiments of the present disclosure can simultaneously fix the motor 500 and the exhaust filter unit 226 using the mounting bracket 600, which has the advantages of high integration, convenient assembly and cost saving.

[0197] In some embodiments of the present disclosure, as shown in FIG. 25 , FIG. 27 and FIG. 28 , the filter mounting portion 630 includes a frame 631 and a buckle 632 .

[0198] A 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 226. A buckle 632 is connected to the frame 631 and is located on the side of the exhaust filter 226 facing away from the bracket body 610, and is configured to block the exhaust filter 226.

[0199] For example, the frame 631 may be circular, rectangular, polygonal or other shapes, and may be specifically set according to the shape of the exhaust filter portion 226 so that the frame 631 can surround the exhaust filter portion 226 .

[0200] The exhaust filter 226 can be parallel to the bracket body 610, and the bracket body 610 can be configured to separate the motor mounting portion 620 and the filter mounting portion 630. In other words, the motor mounting portion 620 and the exhaust filter 226 can be located on opposite sides of the thickness direction of the bracket body 610. In this way, the motor 500 and the exhaust filter 226 can be located on opposite sides of the thickness direction of the bracket body 610, thereby utilizing the bracket body 610 to separate the motor 500 and the exhaust filter 226, thereby preventing positional interference between the motor 500 and the exhaust filter 226 and achieving a more rational structural arrangement.

[0201] In addition, the frame 631 can extend along the circumference of the exhaust filter 226, thereby shielding the edge of the exhaust filter 226 with the frame 631, thereby improving the protection of the exhaust filter 226. Furthermore, the buckle 632 and the bracket body 610 can respectively stop at opposite sides of the thickness direction of the exhaust filter 226. The bracket body 610 can prevent the exhaust filter 226 from excessively extending into the mounting bracket 600, while the buckle 632 can prevent the exhaust filter 226 from separating from the mounting bracket 600, making the connection between the exhaust filter 226 and the mounting bracket 600 more stable and reliable.

[0202] It should be noted that the number of clips 632 can be multiple, and the multiple clips 632 are distributed at circumferential intervals along the frame 631, and then can be stopped at multiple circumferential positions of the exhaust filter part 226 by the multiple clips 632, 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 part 220.

[0203] In some embodiments of the present disclosure, as shown in FIG. 28 , a flange 633 is configured on a 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 .

[0204] By providing the flange 633, the structural strength of the frame 631 is increased, making the frame 631 less susceptible to deformation. This increases the connection strength between the frame 631 and the exhaust filter 226, allowing the frame 631 to more reliably secure the exhaust filter 226. Furthermore, by bending the flange 633 away from the exhaust filter 226, the flange 633 does not interfere with the position of the exhaust filter 226, thereby facilitating assembly of the exhaust filter 226 and the mounting bracket 600.

[0205] In some embodiments of the present disclosure, as shown in Figures 27 and 28, the 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 clamped between the motor mounting portion 620 and the buckle 632.

[0206] For example, the side of the motor mounting portion 620 facing the exhaust filter portion 226 protrudes 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 that the positioning of the exhaust filter portion 226 is more stable and the exhaust filter portion 226 is prevented from moving.

[0207] 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 it stops 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.

[0208] In some embodiments of the present disclosure, as shown in FIG. 26 and FIG. 29 , the motor mounting portion 620 includes a base 621 and a plurality of fixing columns 622 .

[0209] The base 621 is configured to support one axial end of the motor 500, and 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.

[0210] 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.

[0211] After the motor 500 is mounted on the motor mounting portion 620, a stop plate can be connected to the end of the fixing column 622 facing away from the base 621. The stop plate can be stopped by the end of the motor 500 facing away from the base 621. A through hole can be provided in the center of the stop plate to facilitate the passage of the output shaft 510 through the stop plate. The stop plate can be the same component as the motor pressure plate 540 in the above embodiment.

[0212] In addition, there may be at least three fixing posts 622. Thus, the plurality of fixing posts 622 can position the motor 500 in the radial direction, preventing the motor 500 from radially deviating relative to the motor mounting portion 620, while the base 621 and the stop plate can respectively stop at both axial ends of the motor 500, thereby fixing the motor 500 in the axial direction and preventing the motor 500 from axially deviating.

[0213] In some embodiments of the present disclosure, as shown in Figures 24, 26, and 29, 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. The wiring harness 550 of the motor 500 sequentially passes through the first wire-passing portion 611 and the second wire-passing portion 634. The first wire-passing portion 611 can be configured as a first wire-passing hole, and the second wire-passing portion 634 can be configured as a second wire-passing hole.

[0214] For example, 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 can pass 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, by passing the wiring harness 550 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, so that the routing of the wiring harness 550 in the ventilation component 200 is more regular, which is convenient for layout.

[0215] In some embodiments of the present disclosure, as shown in Figures 26 to 29, the bracket body 610 is configured with a grille 612, which avoids the motor mounting portion 620. The grille 612 is formed with a hollow portion 613, at least one of the plurality of hollow portions 613 being configured as a first wire passing portion 611. The hollow portion 613 can be configured as a grille hole.

[0216] It is understood that the hollow portion 613 is usually set to be small. 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, making it easier for the wiring harness 550 of the motor 500 to pass through the first wire-passing portion 611, and making assembly more convenient.

[0217] In some embodiments of the present disclosure, as shown in Figures 27 and 28, a limiting rib 614 is provided on the bracket body 610. The limiting rib 614 is located on one side of the wire harness 550 to constrain 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. In this way, the limiting rib 614 can constrain the wire harness 550 as it extends from the first wire passing portion 611 to the second wire passing portion 634.

[0218] In some examples, there may be multiple limiting ribs 614. For example, two limiting ribs 614 may be provided. One limiting rib 614 is connected to the bracket body 610 and extends along the axial direction of the bracket body 610. The wiring harness 550 may 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 wiring harness 550 and prevent the wiring harness 550 from deviating in the radial direction of the mounting bracket 600. In addition, another limiting rib 614 can be connected to the side of the motor mounting portion 620 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 facing away from the mounting bracket 600. In this way, 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, facilitating layout.

[0219] As shown in FIG. 22 to FIG. 29 , the cabinet air conditioner according to some embodiments of the present disclosure includes a casing 100 , a heat exchanger, a heat exchange fan, and a ventilation assembly 200 .

[0220] The housing 100 has an upper chamber and a lower chamber. A heat exchanger is located in the upper chamber, and a heat exchange blower is configured to deliver air that has exchanged heat with the heat exchanger into the room. The ventilation assembly 200 is located in the lower chamber and is configured to deliver outdoor air into the room, and indoor air to either the indoor or outdoor space.

[0221] 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 .

[0222] A first duct member 210 is disposed in the lower chamber. A first duct member 210 defines a first duct 201, through which fresh outdoor air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 220 defines a second duct 202, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed in the second duct 202 to deliver indoor air to the indoors or outdoors, while a second fan 400 is disposed in the first duct 201 to deliver outdoor air indoors. A motor 500 has a single output shaft 510. The first and second fans 300 and 400 are transmission-connected to the output shaft 510. The motor 500 drives the first and second fans 300 and 400 to rotate synchronously via the output shaft 510. An exhaust filter 226 is disposed on the air inlet side of the second duct 202 to purify the indoor air entering the second duct 202.

[0223] The mounting bracket 600 is connected to the second air duct member 220 , and the motor 500 and the exhaust filter portion 226 are both mounted on the mounting bracket 600 .

[0224] Thus, the housing 100 is provided with an upper chamber and a lower chamber, the heat exchanger is provided in the upper chamber, the heat exchange blower is configured to deliver air after heat exchange with the heat exchanger into the room, and the ventilation assembly 200 is provided in the lower chamber. The ventilation assembly 200 is configured to deliver outdoor air into the room, and to deliver indoor air to the room or the outside. In this way, the ventilation assembly 200 can introduce outdoor air into the room through the first air duct 201, thereby purifying the indoor air with outdoor fresh air. Alternatively, the ventilation assembly 200 can exhaust the indoor air to the outside, thereby exhausting the relatively dirty indoor air to the outside, so as to quickly purify the indoor air after the introduction of outdoor air. Alternatively, the ventilation assembly 200 can draw indoor air into the housing 100, exchange heat with the heat exchanger, and then discharge it into the room, thereby quickly achieving indoor cooling or heating.

[0225] Furthermore, a first duct member 210 is disposed in the lower chamber. A first duct member 201 is formed within the first duct member 210, through which outdoor fresh air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 202 is formed within the second duct member 220, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed within the second duct member 202 to deliver indoor air indoors or outdoors, while a second fan 400 is disposed within the first duct member 201 to deliver outdoor air indoors. In this way, the first duct member 210 can direct the outdoor fresh air, while the second duct member 220 can direct the indoor air, thereby separating the flow of outdoor fresh air and indoor air, preventing interference between the outdoor and indoor air flows and ensuring smoother airflow within the cabinet air conditioner.

[0226] Furthermore, the motor 500 has an output shaft 510, to which the first fan 300 and the second fan 400 are transmission-connected. The motor 500, via the output shaft 510, synchronously drives the first fan 300 and the second fan 400 to rotate. Thus, the first fan 300 and the second fan 400 can share a single motor 500, which helps reduce the number of motors 500, resulting in a smaller number of parts in the cabinet air conditioner, easier assembly, and a smaller footprint for the motor 500, thus reducing the volume of the ventilation assembly 200. Furthermore, the exhaust filter 226 is disposed on the air inlet side of the second air duct 202. This allows the exhaust filter 226 to purify the indoor air entering the second air duct 202, improving the quality of the air entering the cabinet air conditioner. This improves the quality of the air discharged by the air conditioner and prevents dust and impurities from entering the housing 100.

[0227] Furthermore, the mounting bracket 600 can be used to simultaneously mount the motor 500 and the exhaust filter 226. In other words, the motor 500 and the exhaust filter 226 can be mounted on a single bracket. This reduces the number of brackets, making the mounting bracket 600 more integrated, more convenient, and more efficient.

[0228] It can be understood that, compared with the related art in which two brackets are provided to fix the motor 500 and the exhaust filter unit 226 respectively, the cabinet air conditioner of some embodiments of the present disclosure can reduce one bracket, thereby saving a set of molds for producing the bracket, which is conducive to reducing the production cost of the installation bracket 600.

[0229] According to some embodiments of the present disclosure, the cabinet air conditioner can simultaneously fix the motor 500 and the exhaust filter 226 using the mounting bracket 600 , which has the advantages of high integration, convenient assembly, and cost savings.

[0230] In some embodiments of the present disclosure, as shown in Figures 24 and 26 to 29, a first wire-passing portion 611 and a second wire-passing portion 634 are provided on the mounting bracket 600, and 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.

[0231] In this way, the wire harness 550 can pass through the second wire pass portion 634 and out of the mounting bracket 600, thereby facilitating electrical connection between the wire harness 550 and the power supply, thereby ensuring electrical continuity between the motor 500 and the power supply. Furthermore, the mounting bracket 600 can also secure the wire harness 550 through the first wire pass portion 611 and the second wire pass portion 634, thereby ensuring a more regular routing of the wire harness 550 within the ventilation assembly 200 and facilitating layout.

[0232] The following describes a cabinet air conditioner according to some embodiments of the present disclosure with reference to the accompanying drawings.

[0233] As shown in FIG. 30 to FIG. 39 , the cabinet air conditioner according to some embodiments of the present disclosure 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 blower.

[0234] 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 housing 100. A heat exchanger is located in the upper chamber, and a fresh air blower is located in the lower chamber. The fresh air blower drives outdoor air into the lower chamber through the fifth air inlet 160. One end of an adapter assembly 700 is connected to the fifth air inlet 160, and the other end of the adapter assembly 700 is connected to the fresh air inlet pipe 730. The adapter assembly 700 connects the fresh air inlet pipe 730 to the fifth air inlet 160.

[0235] 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 is connected to the fifth air inlet 160. The two 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.

[0236] The first adapter 710 can be plugged into or bolted to the housing 100. For example, the first adapter 710 can be configured with mounting ears 716, and the housing 100 can be configured with bolt holes, and the mounting ears 716 of the first adapter 710 can be bolted to the housing 100. The second adapter 720 can be plugged into the fresh air inlet pipe 730. 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.

[0237] The second adapter 720 is rotatable relative to the first adapter 710 , which means that the second adapter 720 can rotate relative to the first adapter 710 along its central axis, or the first adapter 710 can rotate relative to the second adapter 720 along its central axis.

[0238] In some embodiments of the present disclosure, the cabinet air conditioner is provided with a heat exchanger in the upper chamber, and a fresh air blower is provided in the lower chamber. The fresh air blower drives outdoor air into the lower chamber through the fifth air inlet 160. One end of the adapter assembly 700 is connected to the fifth air inlet 160, and the other end of the adapter assembly 700 is connected to the fresh air inlet pipe 730. The adapter assembly 700 connects the fresh air inlet pipe 730 and the fifth air inlet 160. In this way, outdoor air can be guided to the fifth air inlet 160 through the fresh air inlet pipe 730 and then flow into the room through the fifth air inlet 160, thereby purifying the indoor air.

[0239] Furthermore, 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. The two 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. Furthermore, 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.

[0240] 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. In other words, 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.

[0241] For example, as shown in FIG30 , 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 with each other. In other words, the adapter assembly 700 is in a straight line. This facilitates the connection between the fresh air inlet pipe 730 and the fifth air inlet 160 after passing through the wall 740, which helps to reduce the space occupied by the adapter assembly 700. In addition, since the adapter assembly 700 has no bends, the airflow resistance within the adapter assembly 700 is smaller, and 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.

[0242] When the fifth air inlet 160 is tilted relative to the wall 740, for example, as shown in FIG38 , the fifth air inlet 160 is oriented toward the corner of the wall 740 (i.e., when the fresh air inlet pipe 730 is tilted relative to the central axis of the fifth air inlet 160), the first adapter 710 and the second adapter 720 can be rotated relative to each other to make the adapter assembly 700 bend. In this way, the central axis of the first adapter 710 can coincide with the central axis of the fifth air inlet 160, facilitating the connection between the first adapter 710 and the housing 100 and communication 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, facilitating the connection between the second adapter 720 and the fresh air inlet pipe 730. This makes installation more convenient and quick, and the adapter assembly 700 can occupy a smaller space, which helps to reduce the space required for installation of the cabinet air conditioner.

[0243] 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.

[0244] In this way, the cabinet air conditioner according to some embodiments of the present disclosure can meet the requirements of different installation environments, and has the advantages of high installation efficiency, convenient installation and small installation space.

[0245] In some embodiments of the present disclosure, as shown in FIG34 , one of the first adapter 710 and the second adapter 720 is configured with a second snap-fit ​​structure 721, and the other is configured with a first snap-fit ​​structure 711, and the second snap-fit ​​structure 721 is rotatably snap-fitted into the first snap-fit ​​structure 711. The first snap-fit ​​structure 711 may be a snap-fit ​​ring groove, and the second snap-fit ​​structure 721 may be a snap-fit ​​ring platform.

[0246] For example, the end of the first adapter 710 facing the second adapter 720 may be configured with a first snap-fit ​​structure 711, and the end of the second adapter 720 facing the first adapter 710 may be configured with a second snap-fit ​​structure 721. The first snap-fit ​​structure 711 and the second snap-fit ​​structure 721 snap-fit ​​each other, not only simplifying the connection structure and facilitating the mutual connection between the first adapter 710 and the second adapter 720, but also allowing the second snap-fit ​​structure 721 to rotate within the first snap-fit ​​structure 711, thereby enabling relative rotation between the first adapter 710 and the second adapter 720, and preventing the first adapter 710 and the second adapter 720 from separating during the relative rotation.

[0247] Furthermore, as shown in FIG. 32 to FIG. 37 , the outer contour of the second clamping structure 721 and the inner contour of the first clamping structure 711 are configured as matching circles.

[0248] 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.

[0249] In some embodiments of the present disclosure, as shown in Figures 36 and 37, the central axis of second clip structure 721 forms a first inclination angle with the central axis of one of first adapter 710 and second adapter 720, and the central axis of first clip structure 711 forms a second inclination angle with the central axis of the other of first adapter 710 and second adapter 720. The difference between the first inclination angle and the second inclination angle is A, where A satisfies the following: -10° ≤ A ≤ 10°.

[0250] For example, the first clamping structure 711 can be provided on the first adapter 710, and the second clamping structure 721 can be provided on the second adapter 720. As shown in FIG36 , the angle between the central axis of the first adapter 710 and the central axis of the first clamping structure 711 is C, i.e., the second inclination angle is C; as shown in FIG37 , the angle between the central axis of the second adapter 720 and the central axis of the second clamping structure 721 is B, i.e., the first inclination angle is B.

[0251] The first inclination angle can be equal to the second inclination angle. Thus, 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 be aligned. In other words, when the first adapter 710 and the second adapter 720 are rotated to their extreme positions, the adapter assembly 700 can be linear, allowing the fresh air inlet duct 730 and the fifth air inlet 160 to be connected via the adapter assembly 700 when they are facing each other.

[0252] 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°; or 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°.

[0253] In this way, a squeezing force can be generated between the second clamping structure 721 and the first clamping structure 711, which is beneficial for improving the sealing between the second clamping structure 721 and the first clamping structure 711. In addition, the difference between the first inclination angle and the second inclination angle is not 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 outdoor air flows more smoothly in the adapter assembly 700.

[0254] It is understood that when the first adapter 710 and the second adapter 720 rotate relative to each other, the second clamping structure 721 and the first clamping structure 711 always remain engaged. In other words, the first adapter 710 can be viewed as rotating relative to the second adapter 720 along the central axis of the first clamping structure 711, or the second adapter 720 can be viewed as rotating relative to the first adapter 710 along the central axis of the second clamping structure 721. This allows the angle between the central axis of the first adapter 710 and the central axis of the second adapter 720 to be adjusted, so that the adapter assembly 700 can be adjusted to a straight or curved shape, and the bending angle of the adapter assembly 700 can be adjusted according to the installation position of the cabinet air conditioner.

[0255] In some embodiments of the present disclosure, as shown in FIG. 35 , the first clamping structure 711 includes a stop portion 712 , a main body portion 713 and a clamping portion 714 .

[0256] The plane of the stop portion 712 is perpendicular to the central axis of the first engaging structure 711, and the second engaging structure 721 abuts against the stop portion 712. The main body 713 is connected to the stop portion 712 and surrounds the second engaging structure 721. The engaging portion 714 is connected to the main body 713 and protrudes from the inner circumference of the main body 713. The second engaging structure 721 is engaged between the stop portion 712 and the engaging portion 714.

[0257] Thus, 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 abut against the abutting portion 712. The abutting portion 712 can limit the insertion position of the second clamping structure 721, preventing the first adapter 710 and the second adapter 720 from having an excessively large insertion size. The clamping portion 714 can be clamped to the side of the second clamping structure 721 facing away from the abutting portion 712, thereby fixing the position of the second clamping structure 721 through the clamping portion 714 and the abutting portion 712, thereby ensuring a more stable connection between the first adapter 710 and the second adapter 720 and preventing the first adapter 710 and the second adapter 720 from separating.

[0258] Furthermore, the main body 713 can surround the second clamping structure 721 from its outer circumference. This increases the contact area between the second clamping structure 721 and the first clamping structure 711, enhancing the connection strength between the second clamping structure 721 and the first clamping structure 711 and making the connection between the first adapter 710 and the second adapter 720 more stable and reliable. Furthermore, the main body 713 can limit the radial position of the second clamping structure 721, thereby preventing radial misalignment between the first adapter 710 and the second adapter 720, and providing a more rational structural arrangement.

[0259] In some embodiments of the present disclosure, as shown in FIG. 35 , the snap-fit ​​portion 714 is a plurality of snap hooks 632 , and the plurality of snap hooks 632 are arranged at intervals along the circumference of the main body 713 .

[0260] For example, multiple latches 632 are provided at one end of the main body 713 away from the abutting portion 712, and the latches 632 protrude from the inner circumferential surface of the main body 713. Thus, when the second engaging structure 721 is inserted into the first engaging structure 711, the multiple latches 632 can abut against the second engaging structure 721 at multiple locations along the circumference of the second engaging structure 721, preventing the second engaging structure 721 from separating from the first engaging structure 711, thereby preventing the first adapter 710 and the second adapter 720 from separating from each other.

[0261] Moreover, by providing a plurality of clips 632, the connection stability between the first clip structure 711 and the second clip structure 721 can be improved, and the plurality of clips 632 can simultaneously clip the second clip structure 721, thereby avoiding the connection failure of a single clip 632 causing the connection failure of the first clip structure 711 and the second clip structure 721, thereby further improving the connection reliability of the first adapter 710 and the second adapter 720.

[0262] In some embodiments of the present disclosure, as shown in FIG. 35 , the main body 713 is provided with a plurality of deformation portions 715 , and the plurality of deformation portions 715 are respectively disposed on opposite sides of the buckle 632 .

[0263] 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 clamping structure 721 is inserted into the first clamping 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 quick, and avoiding damage to the clamping portion 714 and the second clamping structure 721 during the installation process.

[0264] In some embodiments of the present disclosure, the second adapter 720 has a first position and a second position. When the second adapter 720 is 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 α between the central axis of the first adapter 710 and the central axis of the second adapter 720 is such that α satisfies the following: 90°≤α≤135°.

[0265] That is, the second adapter 720 and the first adapter 710 have two extreme positions for relative rotation. When the second adapter 720 is in the first position, that is, the second adapter 720 and the first adapter 710 are rotated relative to each other to the first extreme position, the adapter assembly 700 can be straight. When the second adapter 720 is in the second position, that is, the second adapter 720 and the first adapter 710 are rotated relative to each other to the second extreme position, the adapter assembly 700 can be bent, 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°. Thus, the second adapter 720 can rotate between the first position and the second position, thereby adjusting the bending angle of the adapter assembly 700.

[0266] Furthermore, by setting °90≤α≤135°, the first adapter 710 and the second adapter 720 can be rotated relative to each other 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 pipe 730 and the casing 100 respectively.

[0267] In other embodiments of the present disclosure, as shown in FIG. 30 to FIG. 39 , the adapter assembly 700 includes a first adapter 710 and a second adapter 720 .

[0268] The first adapter 710 is connected to the housing 100 and communicates with the fifth air inlet 160 , and the second adapter 720 is connected to the fresh air inlet pipe 730 . The extension direction of the second adapter 720 is adjustable relative to the extension direction of the first adapter 710 .

[0269] Thus, when the fifth air inlet 160 faces 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 point, 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. In other words, the adapter assembly 700 can be linear to facilitate the connection between the first adapter 710 and the housing 100 and the connection between the second adapter 720 and the fresh air inlet duct 730.

[0270] When the fifth air inlet 160 is facing the wall 740 at an angle, the central axis of the fresh air inlet duct 730 can be tilted relative to the central axis of the fifth air inlet 160. In this case, the extension direction of the first adapter 710 and the extension direction of the second adapter 720 can be adjusted to be tilted relative to each other. In other words, the adapter assembly 700 can be curved so that the extension direction of the first adapter 710 coincides with the central axis of the fifth air inlet 160, and the extension direction of the second adapter 720 coincides with the central axis of the fresh air duct. This facilitates the connection between the first adapter 710 and the housing 100, and the connection between the second adapter 720 and the fresh air inlet duct 730, and helps reduce the space occupied by the adapter assembly 700, thereby reducing the installation space of the cabinet air conditioner.

[0271] According to some embodiments of the present disclosure, the cabinet air conditioner can meet the requirements of different installation environments and has the advantages of high installation efficiency, convenient installation and small installation space.

[0272] In some embodiments of the present disclosure, 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°.

[0273] In this way, an angular difference can exist between the central axis of the first adapter 710 and the central axis of the second clamping structure 721. When the second clamping structure 721 rotates relative to the second adapter 720, it can drive the first adapter 710 to rotate. The first adapter 710 can be bent in different directions relative to the second adapter 720, thereby adjusting the angular difference between the first adapter 710 and the second adapter 720, so that the first adapter 710 and the second adapter 720 can form a straight line or a bent shape with different angles.

[0274] Furthermore, by ensuring that β satisfies 10°≤β≤45°, the angle between the first and second cross-sections can be prevented from being too small, thereby allowing a larger angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721. During rotation of the second engaging structure 721 relative to the second adapter 720, the angle between the first adapter 710 and the second adapter 720 can vary widely, facilitating adjustment of the shape of the adapter assembly 700 and enabling the cabinet air conditioner to meet the requirements of various installation environments. Furthermore, the angle between the first and second cross-sections can be prevented from being too large, thereby preventing the first adapter 710 from bending too much relative to the second adapter 720 during rotation of the second engaging structure 721 relative to the second adapter 720, thereby maintaining unimpeded airflow within the adapter assembly 700. Furthermore, the angle between the central axis of the first adapter 710 and the central axis of the second engaging structure 721, which could result in a decrease in the structural strength of the first adapter 710 and the second engaging structure 721, can be prevented, thereby ensuring the overall structural strength of the adapter assembly 700 remains high.

[0275] The cabinet air conditioner according to some embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0276] As shown in FIG. 40 to FIG. 51 , the cabinet air conditioner according to some embodiments of the present disclosure includes a main body, which includes a casing 100 , a heat exchanger, and a ventilation assembly 200 .

[0277] 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 configured to send outdoor air to the room, and send indoor air to the outside or the outside.

[0278] 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 .

[0279] A 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, through which outdoor air enters the room. A 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, through which indoor air is delivered to the room or outdoors. A first fan 300 is disposed in the second air duct 202 to deliver indoor air to the room or outdoors. A second fan 400 is disposed in the first air duct 201 to deliver outdoor air to the room. The motor 500 has a single output shaft 510, to which the first fan 300 and the second fan 400 are transmission-connected.

[0280] One of the first fan 300 and the second fan 400 is provided with a first rotation stop 320, and the other is provided with a second rotation stop 420. The first rotation stop 320 and the second rotation stop 420 cooperate with each other. When the motor 500 is in operation, the motor 500 drives the first fan 300 and the second fan 400 to rotate. The first rotation stop 320 and the second rotation stop 420 cooperate to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0281] In some embodiments of the cabinet air conditioner disclosed herein, 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 assembly 200 is provided in the lower chamber. The ventilation assembly 200 is configured to deliver outdoor air to the room, and to deliver indoor air to the room or to the outside. In this way, the ventilation assembly 200 can introduce outdoor air into the room through the first air duct 201, thereby purifying the indoor air with outdoor fresh air. Alternatively, the ventilation assembly 200 can exhaust the indoor air to the outside, thereby exhausting the relatively dirty indoor air to the outside, so as to quickly purify the indoor air after the introduction of outdoor air. Alternatively, the ventilation assembly 200 can draw indoor air into the casing 100, exchange heat with the heat exchanger, and then discharge it into the room, thereby quickly achieving indoor cooling or heating.

[0282] Furthermore, a first duct member 210 is disposed in the lower chamber. A first duct member 201 is formed within the first duct member 210, through which outdoor air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 202 is formed within the second duct member 220, through which indoor air is delivered to the room or outdoors. A first fan 300 is disposed within the second duct member 202 to deliver indoor air to the room or outdoors. A second fan 400 is disposed within the first duct member 201 to deliver outdoor air to the room. In this way, the first duct member 210 can direct outdoor fresh air, while the second duct member 220 can direct indoor air, thereby separating the flow of outdoor fresh air and indoor air, preventing interference between the outdoor and indoor air flows and ensuring smoother airflow within the cabinet air conditioner.

[0283] Furthermore, the motor 500 has a single output shaft 510, to which the first fan 300 and the second fan 400 are drivingly connected. In other words, the first fan 300 and the second fan 400 can share a single motor 500, thereby reducing the number of motors 500, thereby reducing the number of parts in the cabinet air conditioner, making assembly more convenient, and reducing the space occupied by the motor 500, thereby reducing the volume of the ventilation assembly 200.

[0284] Furthermore, one of the first fan 300 and the second fan 400 is provided with a first stopper 320, and the other is provided with a second stopper 420. The first stopper 320 and the second stopper 420 cooperate with each other. When the motor 500 is in operation, the motor 500 drives the first fan 300 and the second fan 400 to rotate, and the first stopper 320 and the second stopper 420 cooperate to drive the first fan 300 and the second fan 400 to rotate at the same frequency.

[0285] It should be noted that the first and second stoppers 320 and 420 cooperate to prevent the second and first fans 400 and 300 from rotating circumferentially around the output shaft 510. This prevents relative rotation between the second and first fans 400 and 300, allowing them to rotate synchronously with the output shaft 510. Furthermore, the cooperation between the first and second stoppers 320 and 420 also ensures proper positioning of the second and first fans 400 and 300 for assembly.

[0286] Thus, even if the first and second fans 300 and 400 experience different wind resistances, the first and second stoppers 320 and 420 cooperate to allow the faster fan to drive the slower fan, while the faster fan is affected by the slower fan and its speed is reduced. For example, if the second fan 400 experiences greater wind resistance and the first fan 300 experiences less wind resistance, the speed of the second fan 400 may be lower than that of the first fan 300. With the first and second stoppers 320 and 420 engaged, the first fan 300 can drive the second fan 400 to accelerate, while the speed of the first fan 300 is affected by the second fan 400 and its speed is reduced. This allows the first and second fans 300 and 400 to maintain consistent speeds and rotate at the same frequency, reducing rotational noise and vibration of the first and second fans 300 and 400, thereby improving the performance of the air conditioner.

[0287] In this way, the cabinet air conditioner according to some embodiments of the present disclosure can make the first fan 300 and the second fan 400 rotate at the same frequency, which is beneficial to reducing vibration and noise and improving the use effect of the air conditioner.

[0288] In some embodiments of the present disclosure, as shown in FIG. 44 and FIG. 45 , a first hub 330 is provided 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 mating portion 340 .

[0289] As shown in Figures 47 and 48 , the second fan 400 is provided with a second hub 430 on the side facing the first fan 300. The second hub 430 is recessed toward the first fan 300 to form a second mating portion 440. One of the first mating portion 340 and the second mating portion 440 is provided with the first rotation stop 320, and the other is provided with the second rotation stop 420.

[0290] 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 .

[0291] By protruding the first mating portion 340 toward the second fan 400 and recessing the second mating portion 440 toward the first fan 300, the first mating portion 340 and the second mating portion 440 can be closer to each other, so that the first mating portion 340 and the second mating portion 440 can be in contact and mated, and the first stop portion 320 and the second stop portion 420 can be stably and reliably mated 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.

[0292] Further, as shown in Figures 46 and 49, the first anti-rotation portion 320 is an anti-rotation protrusion and is provided in plurality, and the plurality of anti-rotation protrusions are arranged circumferentially along the first matching portion 340, and the second anti-rotation portion 420 is an anti-rotation groove and is provided in plurality, and the plurality of anti-rotation grooves are arranged circumferentially along the second matching portion 440, and the plurality of anti-rotation protrusions are inserted into the plurality of anti-rotation grooves in a one-to-one correspondence.

[0293] 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, effectively ensuring the rotation synchronization of the second fan 400 and the first fan 300, and reducing the rotation noise and rotation vibration of the second fan 400 and the first fan 300, thereby improving the use effect of the air conditioner.

[0294] Moreover, by setting the first stop part 320 and the second stop part 420 as a combination of a protrusion and a groove, it is not only beneficial to simplify the structure of the first stop part 320 and the second stop part 420, facilitating 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 into 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.

[0295] It is understood that the first stop 320 and the second stop 420 may also have other mating structures. For example, the first stop 320 and the second stop 420 may both be protrusions, and the protrusions on the first mating portion 340 and the protrusions on the second mating portion 440 are circumferentially staggered so that the protrusions on the first mating portion 340 and the protrusions on the second mating portion 440 can abut against each other, thereby allowing the two fans to rotate at the same frequency.

[0296] In some embodiments of the present disclosure, as shown in Figures 46 and 49, the anti-rotation protrusion has a first side surface 321 and a second side surface 322 that are opposed to each other in the circumferential direction of the first mating portion 340, and is close to the anti-rotation groove in the axial direction of the first mating portion 340, with the first side surface 321 and the second side surface 322 being close to each other. The anti-rotation groove has a first wall surface 421 and a second wall surface 422 that are opposed to each other in the circumferential direction of the second mating portion 440, and is away from the anti-rotation protrusion in the axial direction of the second mating portion 440, with the first wall surface 421 and the second wall surface 422 being close to each other.

[0297] That is, the first side surface 321 and the second side surface 322 can be configured as inclined surfaces, and the first wall surface 421 and the second wall surface 422 can also be configured as inclined surfaces. Furthermore, 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.

[0298] Thus, 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 large contact area, and the second side surface 322 and the second wall surface 422 can abut against each other with a large contact area. In this way, the anti-rotation protrusion and the anti-rotation groove can fit more tightly, further improving 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.

[0299] Furthermore, with this arrangement, the width of the anti-rotation protrusion at the end away from the first mating portion 340 can be smaller, while the opening width of the anti-rotation groove can be larger, making it easier to insert the anti-rotation protrusion into the anti-rotation groove. In other words, the anti-rotation protrusion and the anti-rotation groove can guide the assembly of the second fan 400 and the first fan 300, which helps to simplify the assembly of the second fan 400 and the first fan 300 and improve assembly efficiency.

[0300] 46 and 49 , the first side surface 321 and the second side surface 322 are spaced apart from each other radially outward from the first mating portion 340. The first wall surface 421 and the second wall surface 422 are spaced apart from each other radially outward from the second mating portion 440.

[0301] It is understood that, along the radial direction of the first mating portion 340, the closer to the central axis of the first mating portion 340, the smaller the radius of the first mating portion 340, and the smaller the circumferential space available for arranging the anti-rotation protrusion. Furthermore, as the radius of the first mating portion 340 increases radially outward from the first mating portion 340, the circumferential space available for arranging the anti-rotation protrusion also increases, increasing the distance between the first side surface 321 and the second side surface 322. In this way, the anti-rotation protrusions can fully utilize the space on the first mating portion 340, avoid adjacent anti-rotation protrusions being too close to each other, and achieve a more reasonable layout.

[0302] Similarly, along the radial direction of the second mating portion 440, the closer to the central axis of the second mating portion 440, the smaller the radius of the second mating portion 440, and the smaller the space available for arranging the anti-rotation groove in the circumferential direction. Furthermore, as the radius of the second mating portion 440 increases radially outward from the second mating portion 440, the space available for arranging the anti-rotation groove in the circumferential direction also increases, increasing the distance between the first wall surface 421 and the second wall surface 422. In this way, the anti-rotation grooves can fully utilize the space on the second mating portion 440, avoid adjacent anti-rotation grooves being too close to each other, and achieve a more reasonable layout.

[0303] Furthermore, the first side surface 321 and the second side surface 322 may also be configured as inclined surfaces in the radial direction of the first mating portion 340, and the first wall surface 421 and the second wall surface 422 may also be configured as inclined surfaces in the radial direction of the second mating portion 440. This further increases the contact area between the first side surface 321 and the first wall surface 421, as well as the contact area between the second side surface 322 and the second wall surface 422, and the fit between the anti-rotation protrusion and the anti-rotation groove becomes tighter, thereby increasing the connection stability between the first fan 300 and the second fan 400.

[0304] In some embodiments of the present disclosure, as shown in Figures 46 and 49 , a side of the anti-rotation protrusion away from the center of the first mating portion 340 is configured as a third side surface 323, and is close to the anti-rotation groove along the axial direction of the first mating portion 340, and the third side surface 323 is inclined toward the center of the first mating portion 340. A side of the anti-rotation groove away from the center of the second mating portion 440 is configured as a third wall surface 423, and is away from the anti-rotation protrusion along the axial direction of the second mating portion 440, and the third wall surface 423 is inclined toward the center of the second mating portion 440.

[0305] In other words, the third side surface 323 can also be configured as an inclined surface, and the third wall surface 423 can also be configured as an inclined surface. This increases the contact area between the third side surface 323 and the third wall surface 423. 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, making the anti-rotation protrusion and the anti-rotation groove fit more tightly, further improving the mating stability of the anti-rotation protrusion and the anti-rotation groove, ensuring that the second fan 400 and the first fan 300 do 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.

[0306] 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 conducive to simplifying the assembly of the second fan 400 and the first fan 300 and improving the assembly efficiency.

[0307] In some embodiments of the present disclosure, as shown in Figures 50 and 51 , the first fan 300 further includes a first insert 350. The first insert 350 is fixed within the first hub 330, sleeved around the output shaft 510, and transmission-connected thereto. The second fan 400 further includes a second insert 450, which is fixed within the second hub 430, sleeved around the output shaft 510, and transmission-connected thereto.

[0308] The first insert 350 can be injection molded and disposed within the first hub 330. The hardness of the first insert 350 can be greater than that of the first hub 330. This improves the fit stability between the first fan 300 and the output shaft 510, and reduces the gap between the first insert 350 and the output shaft 510, allowing the output shaft 510 to more stably drive the first fan 300. Furthermore, the second insert 450 can be injection molded and disposed within the second hub 430. The hardness of the second insert 450 can be greater than that of the second hub 430. This improves the fit stability between the second fan 400 and the output shaft 510, and reduces the gap between the second insert 450 and the output shaft 510, allowing the output shaft 510 to more stably drive the second fan 400.

[0309] Furthermore, as shown in Figure 51, the outer contour of the output shaft 510 is non-circular, the first insert 350 is constructed with a first anti-rotation portion 351 that is adapted to the outer contour of the output shaft 510, and the second insert 450 is constructed with a second anti-rotation portion 451 that is 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.

[0310] 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.

[0311] Thus, 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. In other words, the output shaft 510 and the first fan 300 will not rotate relative to each other, so that the output shaft 510 can drive the first fan 300 to rotate.

[0312] 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. In other words, the output shaft 510 and the second fan 400 will not rotate relative to each other, so that the output shaft 510 can drive the second fan 400 to rotate.

[0313] 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 part 351, and there will be a certain gap between the output shaft 510 and the second anti-rotation part 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 some embodiments of the present disclosure, after the second fan 400 and the first fan 300 are connected and positioned through the first anti-rotation part 320 and the second anti-rotation part 420, the second fan 400 and the first fan 300 will not rotate relative to each other or the relative rotation amplitude will be small, thereby reducing the rotation noise and rotation vibration of the second fan 400 and the first fan 300, and improving the use effect of the air conditioner.

[0314] As shown in FIG. 40 to FIG. 51 , the cabinet air conditioner according to some embodiments of the present disclosure includes a main body, which includes a casing 100 , a heat exchanger, and a ventilation assembly 200 .

[0315] 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 configured to send outdoor air to the room, and send indoor air to the outside or the outside.

[0316] 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 .

[0317] For example, 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. The ventilation component 200 is configured to send outdoor air into 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 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 the outdoor air is introduced. Alternatively, the ventilation component 200 can draw 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.

[0318] Furthermore, a first duct member 210 is disposed in the lower chamber. A first duct member 201 is formed within the first duct member 210, through which outdoor air enters the room. A second duct member 220 is disposed in the lower chamber. A second duct member 202 is formed within the second duct member 220, through which indoor air is delivered to the room or outdoors. A first fan 300 is disposed within the second duct member 202 to deliver indoor air to the room or outdoors, while a second fan 400 is disposed within the first duct member 201 to deliver outdoor air to the room. In this way, the first duct member 210 can direct outdoor fresh air, while the second duct member 220 can direct indoor air, thereby separating the flow of outdoor fresh air and indoor air, preventing interference between the two air flows and ensuring smoother airflow within the cabinet air conditioner.

[0319] Furthermore, the motor 500 has a single output shaft 510, to which the first fan 300 and the second fan 400 are drivingly connected. In other words, the first fan 300 and the second fan 400 can share a single motor 500, thereby reducing the number of motors 500, thereby reducing the number of parts in the cabinet air conditioner, making assembly more convenient, and reducing the space occupied by the motor 500, thereby reducing the volume of the ventilation assembly 200.

[0320] Furthermore, the first fan 300 and the second fan 400 are connected to rotate at the same frequency.

[0321] 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 resistance, after the first fan 300 and the second fan 400 are connected, 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 its speed decreases. For example, if the wind resistance of the second fan 400 is large and the wind resistance of the first fan 300 is small, the speed of the second fan 400 will be lower than the 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 speed decreases, so that the first fan 300 and the second fan 400 can maintain a consistent speed. 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 improving the use effect of the air conditioner.

[0322] According to some embodiments of the present disclosure, the cabinet air conditioner can make the first fan 300 and the second fan 400 rotate at the same frequency, which is beneficial to reducing vibration and noise and improving the use effect of the air conditioner.

[0323] In some embodiments of the present disclosure, as shown in Figures 42, 46 and 49, a stop protrusion is provided on the side of the first fan 300 facing the second fan 400, and a stop groove is provided on the side of the second fan 400 facing the first fan 300, and the stop protrusion is inserted into the stop groove.

[0324] By configuring the connection between the first fan 300 and the second fan 400 as a mating protrusion and groove, not only is the connection structure between the first fan 300 and the second fan 400 simplified, facilitating manufacturing, but also simplifies 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, completing the connection between the first fan 300 and the second fan 400, and improving assembly efficiency.

[0325] 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.

[0326] The cabinet air conditioner according to some embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0327] As shown in Figures 52 to 58, the cabinet air conditioner according to some embodiments of the present disclosure includes a main body, which includes a casing 100, a heat exchanger, a first duct member 210, a second duct member 220, a first fan 300, a second fan 400 and a motor 500.

[0328] The heat exchanger is disposed in the upper chamber, and the first duct member 210 is disposed in the lower chamber. A first duct member 210 defines a first duct 201, through which outdoor air enters the room. A second duct member 220 is disposed in the lower chamber, and a second duct member 220 defines a second duct 202, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed in the second duct 202 to deliver indoor air to the room or outdoors, and a second fan 400 is disposed in the first duct 201 to deliver outdoor air indoors. The motor 500 has a single output shaft 510, to which the first and second fans 300 and 400 are drivingly connected, thereby synchronously driving the rotation of the first and second fans 300 and 400.

[0329] One of the first duct member 210 and the second duct member 220 is provided with an duct member fixing portion 227 , and a free end of the output shaft 510 is rotatably mounted on the duct member fixing portion 227 .

[0330] 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.

[0331] In some embodiments of the present disclosure, the cabinet air conditioner is provided with an upper chamber and a lower chamber, with the heat exchanger disposed in the upper chamber. Furthermore, a first duct member 210 is disposed in the lower chamber, and a first duct 201 is formed therein, through which outdoor air enters the room. A second duct member 220 is disposed in the lower chamber, and a second duct 202 is formed therein, through which indoor air is delivered to the indoor or outdoor space. A first fan 300 is disposed in the second duct 202 to deliver indoor air to the indoor or outdoor space, and a second fan 400 is disposed in the first duct 201 to deliver outdoor air to the indoor space.

[0332] 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 through the outdoor fresh air, or the first fan 300 can discharge the indoor air to the outside, so that the dirtier indoor air can be discharged to the outside, so as to quickly purify the indoor air after introducing outdoor air, or the first fan 300 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.

[0333] Moreover, the first duct member 210 can guide the outdoor fresh air, while the second duct member 220 can guide the indoor air, so as to separate the flow of outdoor fresh air and indoor air, avoid interference between the outdoor air and indoor air during flow, and make the air flow inside the cabinet air conditioner smoother.

[0334] Furthermore, the motor 500 has a single output shaft 510, to which the first fan 300 and the second fan 400 are drivingly connected, thereby synchronously driving the rotation of the first fan 300 and the second fan 400. In other words, the first fan 300 and the second fan 400 can share a single motor 500, thereby reducing the number of motors 500, resulting in a smaller number of parts in the cabinet air conditioner, easier assembly, and a smaller space occupied by the motor 500, thereby reducing the size of the cabinet air conditioner.

[0335] In addition, one of the first duct member 210 and the second duct member 220 is provided with an duct member fixing portion 227 , and the free end of the output shaft 510 is rotatably mounted on the duct member fixing portion 227 .

[0336] For example, the motor 500 may be disposed within the first duct member 210, with the output shaft 510 of the motor 500 extending toward the second duct member 220. In this case, the second duct member 220 may be provided with a duct member fixing portion 227, and the end of the output shaft 510 away from the motor 500 (i.e., the free end of the output shaft 510) may be mounted to the duct member fixing portion 227 of the second duct member 220. Alternatively, the motor 500 may be disposed within the second duct member 220, with the output shaft 510 of the motor 500 extending toward the first duct member 210. In this case, the first duct member 210 may be provided with a duct member fixing portion 227, and the end of the output shaft 510 away from the motor 500 (i.e., the free end of the output shaft 510) may be mounted to the duct member fixing portion 227 of the first 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 set 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 positional interference between the air duct member fixing part 227 and the motor 500 or other components.

[0337] Furthermore, by connecting the free end of the output shaft 510 to 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. The first duct member 210 or the second duct member 220 can support the free end of the output shaft 510, thereby improving the rotational stability of the output shaft 510. The output shaft 510 is less likely to wobble, thereby significantly reducing vibration and noise generated by the output shaft 510 during rotation. This reduces vibration and noise during operation of the cabinet air conditioner, thereby improving the performance of the air conditioner.

[0338] In this way, the cabinet air conditioner according to some embodiments of the present disclosure 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, thereby improving the use effect of the air conditioner.

[0339] In some embodiments of the present disclosure, as shown in FIG. 53 , 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 protrudes toward the output shaft 510 .

[0340] For example, the first duct member 210 is provided with a duct member fixing portion 227, which extends axially along the first fan 300. If the second duct member 220 is provided with a duct member fixing portion 227, the duct member fixing portion 227 extends axially along the second fan 400. This arrangement not only facilitates mounting the free end of the output shaft 510 on the duct member fixing portion 227, making assembly more convenient, but also reduces the radial shielding area of ​​the first duct member 210 or the second duct member 220 by the duct member fixing portion 227, thereby preventing the duct member fixing portion 227 from excessively blocking the air inlet, thereby facilitating the entry of indoor air into the first duct member 210 or the entry of outdoor fresh air into the second duct member 220.

[0341] In addition, the duct member fixing portion 227 is provided to protrude toward the output shaft 510, that is, the duct member fixing portion 227 protrudes from the first duct member 210 or the second duct member 220. In this way, the distance between the duct member fixing portion 227 and the free end of the output shaft 510 can be closer, making it easier to insert the output shaft 510 into the duct member fixing portion 227, and facilitating assembly.

[0342] In some embodiments of the present disclosure, as shown in FIG53 , the central axis of the duct member fixing portion 227 coincides with the central axis of the output shaft 510. In this way, 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, making the rotation of the output shaft 510 more stable. Moreover, 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, this can simplify the assembly of the output shaft 510 and the duct member fixing portion 227. On the other hand, this 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, thereby facilitating layout and avoiding positional interference between components.

[0343] In addition, in some embodiments, as shown in FIG53 , the outer diameter of the duct member fixing portion 227 can be reduced along the axial direction of the duct member fixing portion 227 as it approaches the output shaft 510. This allows the outer diameter of the connection between the duct member fixing portion 227 and the first duct member 210 or the second duct member 220 to be larger, resulting in a stronger connection between the duct member fixing portion 227 and the first duct member 210 or the second duct member 220, and a greater stability of the duct member fixing portion 227, making it less likely to shake. This allows the duct member fixing portion 227 to more reliably support the free end of the output shaft 510, thereby ensuring more stable rotation of the output shaft 510 and reducing rotational vibration and noise of the output shaft 510, thereby improving the performance of the air conditioner.

[0344] In some embodiments of the present disclosure, as shown in Figure 57, 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.

[0345] The first fan 300 and the second fan 400 are mounted on and 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 fastener 520 is provided on the output shaft fixing portion 512. The first fan 300 and the second fan 400 are retained between the motor 500 and the fastener 520. The support section 513 is connected to the other end of the output shaft fixing portion 512 and is rotatably inserted into the duct member fixing portion 227.

[0346] The outer contour of the transmission section 511 can 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 can drive the second fan 400 and the first fan 300 to rotate.

[0347] In addition, the fastener 520 may be a nut. After the first fan 300 and the second fan 400 are mounted on the transmission section 511, the nut may be threadedly engaged with the output shaft fixing portion 512. Thus, the fastener 520 may be used to positionally 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 mounted on the transmission section 511, thereby preventing positional displacement of the first fan 300 and the second fan 400, and further reducing vibration and noise generated by the second fan 400 and the first fan 300 during rotation.

[0348] Furthermore, by providing the support section 513, the support section 513 extends beyond the side of the fastener 520 facing away from the second fan 400. This allows the support section 513 to be connected to the duct member fixing portion 227. The duct member fixing portion 227 supports the output shaft 510 by supporting the support section 513, thus preventing positional interference between the output shaft fixing portion 512, the fastener 520, and the duct member fixing portion 227. This makes it easier for the free end of the output shaft 510 to fit within 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.

[0349] In some embodiments of the present disclosure, as shown in FIG. 54 and FIG. 56 , the duct member fixing portion 227 is provided with a sleeve fixing structure 228 , a sleeve 560 is installed in the sleeve fixing structure 228 , and the output shaft 510 is passed through the sleeve 560 .

[0350] The sleeve fixing structure 228 may be configured as a fixing hole.

[0351] For example, the sleeve 560 can be fixed in the sleeve fixing structure 228 of the air duct member fixing portion 227. By having the output shaft 510 pass through the sleeve 560 and the output shaft 510 rotate relative to the sleeve 560, the sleeve 560 can be used to support the output shaft 510, thereby reducing vibration during rotation of the output shaft 510. On the other hand, the sleeve 560 can reduce the resistance of the output shaft 510 during rotation, and the rotational friction between the sleeve 560 and the output shaft 510 can be reduced, thereby reducing wear on the output shaft 510 and making the output shaft 510 rotate more easily.

[0352] Furthermore, as shown in FIG. 56 , the sleeve fixing structure 228 includes a receiving section 2281 and a stopping section 2282 .

[0353] The stop section 2282 is provided on the side of the accommodating section 2281 facing away from the output shaft 510. The inner diameter of the accommodating section 2281 is larger than the inner diameter of the stop section 2282. The shaft sleeve 560 is mounted on the accommodating section 2281 and stops at the stop section 2282.

[0354] That is, the sleeve 560 is installed in the accommodating section 2281, and the stop section 2282 can limit the axial direction of the sleeve 560. In this way, 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.

[0355] In addition, the output shaft 510 can pass through the sleeve 560 and extend into the stop section 2282. The stop section 2282 can prevent the output shaft 510 from interfering with the hole wall of the sleeve fixing structure 228, thereby facilitating the rotation of the output shaft 510. Alternatively, the output shaft 510 can be inserted into the sleeve 560 but not extend out of it. In other words, the output shaft 510 does not extend into the stop section 2282. By providing the stop section 2282, the weight of the duct member fixing portion 227 can be reduced, making it easier for the duct member fixing portion 227 to be fixed to the first duct member 210 or the second duct member 220, and the duct member fixing portion 227 is less likely to shake, thereby allowing the duct member fixing portion 227 and the sleeve 560 to support the free end of the output shaft 510.

[0356] In some embodiments of the present disclosure, as shown in FIG58 , a sleeve 560 is provided with a shaft hole 562 and a plurality of vibration damping portions 565. The output shaft 510 is passed through the shaft hole 562, and the plurality of vibration damping portions 565 are arranged at intervals along the circumference of the shaft hole 562. The vibration damping portions 565 can be configured as vibration damping holes.

[0357] Lubricating oil can be applied to the shaft hole 562 to facilitate relative rotation between the output shaft 510 and the sleeve 560. Furthermore, the provision of multiple vibration damping portions 565 not only reduces the weight of the sleeve 560 but also reduces the transmission of vibration from the output shaft 510. In other words, the amount of vibration transmitted from the output shaft 510 to the duct member fixing portion 227 via the sleeve 560 can be reduced. The sleeve 560 can cushion the vibration of the output shaft 510, further reducing vibration and noise in the cabinet air conditioner and improving the performance of the air conditioner.

[0358] In some embodiments of the present disclosure, as shown in FIG. 58 , the sleeve 560 includes an inner sleeve 561 and an outer sleeve 563 .

[0359] The inner sleeve 561 is configured with an axial hole 562. The outer sleeve 563 is disposed outside the inner sleeve 561. The outer sleeve 563 and the inner sleeve 561 are connected by a plurality of connecting ribs 564. The outer sleeve 563, the inner sleeve 561 and the adjacent connecting ribs 564 constitute a vibration damping portion 565.

[0360] The plurality of connecting ribs 564 may be arranged at intervals along the circumference of the sleeve 560 . In other words, the plurality of vibration damping portions 565 may be arranged at intervals along the circumference of the sleeve 560 .

[0361] With this arrangement, multiple connecting ribs 564 can respectively connect the inner sleeve 561 and the outer sleeve 563, which not only can construct a vibration damping part 565 between adjacent connecting ribs 564 so that the sleeve 560 can weaken the vibration transmission of the output shaft 510, but also can 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.

[0362] As shown in Figures 52 to 58, the cabinet air conditioner according to some embodiments of the present disclosure includes a main body, which includes a casing 100, a heat exchanger, a first duct member 210, a second duct member 220, a first fan 300, a second fan 400 and a motor 500.

[0363] The heat exchanger is disposed in the upper chamber, and the first duct member 210 is disposed in the lower chamber. A first duct member 210 defines a first duct 201, through which outdoor air enters the room. A second duct member 220 is disposed in the lower chamber, and a second duct member 220 defines a second duct 202, through which indoor air is delivered indoors or outdoors. A first fan 300 is disposed in the second duct 202 to deliver indoor air indoors or outdoors, and a second fan 400 is disposed in the first duct 201 to deliver outdoor air indoors. The motor 500 has a single output shaft 510, to which the first and second fans 300 and 400 are drivingly connected. The motor 500 drives the first and second fans 300 and 400 to rotate synchronously via the output shaft 510.

[0364] A shaft sleeve 560 is provided on one of the first air duct member 210 and the second air duct member 220 , and an end of the output shaft 510 away from the motor 500 is rotatably passed through the shaft sleeve 560 .

[0365] For example, the motor 500 can be disposed within the first duct member 210, with the output shaft 510 of the motor 500 extending toward the second duct member 220. In this case, the sleeve 560 can be disposed on the second duct member 220, and the end of the output shaft 510 away from the motor 500 can be inserted into the sleeve 560 on the second duct member 220. Alternatively, the motor 500 can be disposed within the second duct member 220, with the output shaft 510 of the motor 500 extending toward the first duct member 210. In this case, the sleeve 560 can be disposed on the first duct member 210, and the end of the output shaft 510 away from the motor 500 can be inserted into the sleeve 560 on the first duct member 210.

[0366] Thus, the end of the output shaft 510 away from the motor 500 can be rotatably connected to the sleeve 560. The sleeve 560 can be configured 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 via the output shaft 510. Furthermore, with the sleeve 560 supporting the free end of the output shaft 510, the rotation of the output shaft 510 can be more stable. In other words, the vibration of the output shaft 510 during rotation can be reduced, and the output shaft 510 is less likely to wobble, thereby significantly reducing the vibration of the output shaft 510 and the noise generated by vibration. This reduces the vibration and noise during operation of the cabinet air conditioner, thereby improving the performance of the air conditioner.

[0367] According to some embodiments of the present disclosure, 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, and the vibration and rotation noise are smaller, thereby improving the use effect of the air conditioner.

[0368] In some embodiments of the present disclosure, as shown in Figures 53 to 55 , 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 the end of the output shaft 510 away from the motor 500 is rotatably mounted on the sleeve 560.

[0369] By making the duct member fixing portion 227 protrude from the first duct member 210 or the second duct member 220, it is convenient to fix the sleeve 560 through the duct member fixing portion 227, and the distance between the 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 on the 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 duct member fixing portion 227, making assembly more convenient.

[0370] Other structures and operations of the cabinet air conditioner according to some embodiments of the present disclosure are known to those skilled in the art and will not be described in detail here.

[0371] The cabinet air conditioner of the present disclosure 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.

[0372] The compressor compresses high-temperature, high-pressure refrigerant gas and discharges the compressed gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0373] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the cabinet air conditioner regulates the temperature and humidity of the indoor space.

[0374] Those skilled in the art will understand that the scope of the present disclosure is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present disclosure. The scope of the present disclosure is limited by the appended claims.
