[0002] In related technologies, during the startup of a wall-mounted air conditioner indoor unit, the air intake and fresh air volume are among the standards for inspecting the quality of the air conditioner. After starting the air conditioner, the panel needs to be opened to facilitate the air intake and exhaust. The motor-driven transmission structure guides the panel. The motor and transmission structure need to be fixed to the outer cover to facilitate the movement of the panel. However, there is no limiting structure between the motor and transmission structure and the outer cover, and they are only fastened with screws. This will result in the motor and transmission structure not being able to be effectively and securely installed on the outer cover, and will also complicate the assembly of the wall-mounted air conditioner indoor unit.

[0018] The embodiments of this utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0019] The following is for reference. Figures 1-11 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0020] like Figures 1-11 As shown, the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model includes: a housing 1, an indoor heat exchanger and a drive assembly 2. The housing 1 includes an outer cover 11 and a front panel 12. The outer cover 11 has an air inlet 13 and an air outlet 14. The air inlet 13 is designed to facilitate the intake of indoor air, and the air outlet 14 blows the treated air back into the room, thus effectively forming an air circulation.

[0021] The front panel 12 is movably mounted on the front side of the outer cover 11. When the front panel 12 is fully opened, the entire air outlet 14 and the human sensor camera can be exposed. It can also increase the air intake, thereby increasing the air supply range and avoiding obstruction of the airflow at the air outlet 14.

[0022] The indoor heat exchanger is installed inside the outer casing 11, between the air inlet 13 and the air outlet 14, so that it can exchange heat with the air entering from the air inlet 13. The filter is installed inside the outer casing 11, between the air inlet 13 and the indoor heat exchanger, so that it can filter the air entering from the air inlet 13. This can ensure the cleanliness of the air entering the indoor unit 100 of the wall-mounted air conditioner and the cleanliness of the air blown out.

[0023] The drive assembly 2 is located inside the outer cover 11, which can protect the drive assembly 2 and extend its service life. The drive assembly 2 is connected to the front panel 12 and provides driving force to the front panel 12. This allows the front panel 12 to selectively open and close the front side of the outer cover 11, thereby enabling the front panel 12 to perform corresponding actions based on whether the wall-mounted air conditioner indoor unit 100 is turned on.

[0024] Specifically, the drive assembly 2 includes a drive member 21, a reduction mechanism 22, and a transmission mechanism 23. The reduction mechanism 22 is disposed inside the outer cover 11 and is connected to the drive member 21. The transmission mechanism 23 is connected to the reduction mechanism 22 and the front panel 12 respectively. The reduction mechanism 22 is installed on the outer cover 11 by fasteners 3. A support part 111 is provided inside the outer cover 11. The support part 111 is provided with a first limiting part 112. The reduction mechanism 22 is provided with a second limiting part 221. The first limiting part 112 and the second limiting part 221 are mutually limiting.

[0025] Understandably, the drive component 21, the reduction mechanism 22, and the transmission mechanism 23 constitute the main body of the drive assembly 2. The reduction mechanism 22 is located inside the outer cover 11, which protects the reduction mechanism 22 from impacts by external forces, thereby extending its service life. Furthermore, the reduction mechanism 22 is connected to the drive component 21, allowing the drive force of the drive component 21 to be transmitted to the reduction mechanism 22, which increases the transmission torque of the drive force. For example, the drive component 21 can be a stepper motor, which features simple control, precise positioning, low cost, and fast response, making it convenient for the drive component 21 to provide drive force.

[0026] Optionally, the reduction mechanism 22 includes a planetary gear reduction mechanism 22. A part of the transmission mechanism 23 is connected to the reduction mechanism 22, and the other part of the transmission mechanism 23 is connected to the front panel 12. The power transmission of the drive component 21 passes through the reduction mechanism 22, the transmission mechanism 23, and the front panel 12 in sequence. The reduction mechanism 22 increases the torque of the driving force, so that the drive component 21 with lower power consumption can be used for driving. It can also reduce the size of the transmission mechanism 23, ensuring that the front panel 12 can move relative to the outer cover 11, thereby facilitating the air circulation of the wall-mounted air conditioner indoor unit 100. For example, the planetary gear reduction mechanism 22 has the characteristics of high efficiency, high precision, large load capacity, small size, low noise, and long service life.

[0027] The sun gear, planet carrier, planet gears and ring gear constitute the main body of the planetary gear reduction mechanism 22. The sun gear is located at the center of the planetary gear reduction mechanism 22. The sun gear is connected to the driving member 21. The driving force of the driving member 21 can be transmitted to the sun gear. Then the sun gear rotates at high speed around its own central axis, that is, the sun gear rotates on its own axis, thereby continuing to transmit the driving force.

[0028] The planet carrier is connected to the transmission mechanism 23. The planet gears are located on the planet carrier. The planet carrier can ensure the stability of the force. The planet gears mesh with the sun gear for transmission. The planet carrier drives the planet gears to revolve around the sun gear, and the planet gears also rotate on their own axes, thus forming a dual motion. This allows the planet gears to decelerate the force. The driving force of the drive component 21 is transmitted to the sun gear, and the sun gear then transmits the force to the planet gears. The planet gears increase the torque of the force transmission and then transmit it to the planet carrier and the transmission mechanism 23 in sequence.

[0029] The gear ring is fixed inside the outer cover 11 and is located on the outer circumference of the planetary gears. The gear ring meshes with the planetary gears, which allows the gear ring to provide a reaction force to the planetary gears, forcing the planetary gears to revolve while rotating on their own axis. This allows the planetary gears to achieve a deceleration effect on the force, thereby increasing the transmission torque of the force transmitted from the drive component 21 to the transmission mechanism 23 by the sun gear, planet carrier, planetary gears, and gear ring. This allows the use of a low-power drive component 21, reducing the power consumption of the drive component 21 and thus reducing the energy consumption of the wall-mounted air conditioner indoor unit 100.

[0030] Fasteners 3 pass through the deceleration mechanism 22 and the outer cover 11, which allows the deceleration mechanism 22 to be fixed on the outer cover 11. The outer cover 11 has a support part 111 inside. The support part 111 can not only limit the deceleration mechanism 22, but also provide installation guidance for the deceleration mechanism 22, thereby facilitating the transmission of driving force by the deceleration mechanism 22. The support part 111 is provided with a first limiting part 112, and the deceleration mechanism 22 is provided with a second limiting part 221. The first limiting part 112 and the second limiting part 221 limit each other, which allows the deceleration mechanism 22 and the support part 111 to limit each other. This allows the deceleration mechanism 22 to be pre-installed on the support part 111, which simplifies the assembly process between the deceleration mechanism 22 and the support part 111, and also ensures the firmness between the deceleration mechanism 22 and the support part 111. This can save the assembly time of the drive component 2, and further simplify the assembly process of the wall-mounted air conditioner indoor unit 100.

[0031] Therefore, by providing a support part 111 inside the outer casing 11, and providing a first limiting part 112 in the support part 111, and providing a second limiting part 221 in the deceleration mechanism 22, the first limiting part 112 and the second limiting part 221 cooperate in limiting the deceleration mechanism 22 and the support part 111 through the limiting part for pre-installation, and then fixing the deceleration mechanism 22 and the outer casing 11 with fasteners 3, the deceleration mechanism 22 can be effectively and stably installed on the support part 111, and the assembly time of the drive component 2 can be saved, thereby simplifying the assembly process of the wall-mounted air conditioner indoor unit 100.

[0032] In addition, such as Figure 5 , Figure 6 and Figure 9As shown, the drive member 21 is disposed on the side of the deceleration mechanism 22 away from the support portion 111, and the second limiting portion 221 is disposed on the side of the deceleration mechanism 22 close to the support portion 111.

[0033] In other words, the driving component 21 is located on one side of the reduction mechanism 22, and the driving component 21 and the support part 111 are located on the left and right sides of the reduction mechanism 22, respectively. This allows the support part 111 to provide support for the reduction mechanism 22 and the driving component 21. The driving component 21 is connected to the reduction mechanism 22, which allows the driving force of the driving component 21 to be transmitted to the reduction mechanism 22. The second limiting part 221 is located on one side of the reduction mechanism 22 and is close to the support part 111. This facilitates the limiting cooperation between the first limiting part 112 and the second limiting part 221, thereby facilitating the pre-installation of the reduction mechanism 22 on the support part 111 and ensuring the operation of the driving component 21.

[0034] In addition, such as Figure 6 and Figure 9 As shown, the fastener 3 is located at the bottom of the deceleration mechanism 22, and the second limiting part 221 is located on the upper part of the deceleration mechanism 22 on the side near the support part 111.

[0035] It is understandable that the fastener 3 is located on the lower side of the deceleration mechanism 22, and the second limiting part 221 is located on the upper side of the deceleration mechanism 22. The fastener 3 and the second limiting part 221 are arranged vertically and vertically. When the deceleration mechanism 22 is about to be assembled on the outer cover 11, the second limiting part 221 and the first limiting part 112 cooperate to limit the deceleration mechanism 22. This allows the deceleration mechanism 22 to be pre-installed on the support part 111. Then, the fastener 3 is fixed between the deceleration mechanism 22 and the outer cover 11. This allows the deceleration mechanism 22 to be stably installed on the outer cover 11, thereby saving the assembly time of the drive component 2 and ensuring that the deceleration mechanism 22 will not shake when the wall-mounted air conditioner indoor unit 100 is working.

[0036] Optionally, such as Figures 5-9 As shown, the first limiting part 112 is one of a limiting protrusion and a limiting groove, and the second limiting part 221 is the other of a limiting protrusion and a limiting groove, with the limiting protrusion disposed within the limiting groove. For example, the first limiting part 112 is a limiting groove, and the second limiting part 221 is a limiting protrusion. The limiting protrusion can be engaged in the limiting groove, which facilitates the pre-installation of the deceleration mechanism 22 on the support part 111, thereby saving assembly time between the deceleration mechanism 22 and the support part 111. Alternatively, the first limiting part 112 can be a limiting protrusion, and the second limiting part 221 can be a limiting groove, which also facilitates the pre-installation between the deceleration mechanism 22 and the support part 111.

[0037] In addition, such as Figures 7-10As shown, the outer cover 11 is provided with a third limiting part 113, and the deceleration mechanism 22 is provided with a fourth limiting part 222. The third limiting part 113 and the fourth limiting part 222 cooperate in limiting.

[0038] In other words, a first limiting part 112 is provided on the outer cover 11, and a fourth limiting part 222 is provided on the deceleration mechanism 22. The third limiting part 113 and the fourth limiting part 222 are mutually limiting and cooperating. This allows the deceleration mechanism 22 and the outer cover 11 to be mutually limiting and cooperating, and the deceleration mechanism 22 can be pre-installed on the outer cover 11. This simplifies the assembly process between the deceleration mechanism 22 and the outer cover 11, and also ensures the firmness between the deceleration mechanism 22 and the outer cover 11. This can save the assembly time of the drive component 2, and further simplify the assembly process of the wall-mounted air conditioner indoor unit 100.

[0039] Among them, such as Figures 7-10 As shown, the third limiting part 113 is provided on the top inner side of the outer cover 11, and the fourth limiting part 222 is provided on the top of the deceleration mechanism 22.

[0040] It is understandable that the third limiting part 113 is located on the inner surface of the outer cover 11 and above the deceleration mechanism 22, while the fourth limiting part 222 is located on the upper surface of the deceleration mechanism 22. This facilitates the limiting cooperation between the third limiting part 113 and the fourth limiting part 222, thereby allowing the deceleration mechanism 22 to be pre-installed on the outer cover 11. This saves assembly time between the deceleration mechanism 22 and the outer cover 11 and ensures the stability of the assembly between the deceleration mechanism 22 and the outer cover 11, thus simplifying the assembly process of the wall-mounted air conditioner indoor unit 100.

[0041] In particular, such as Figures 7-10 As shown, the fourth limiting part 222 is disposed at the top front end of the deceleration mechanism 22, that is, the fourth limiting part 222 is located on the upper surface of the deceleration mechanism 22 and on the side of the deceleration mechanism 22 facing the front panel 12. After the fourth limiting part 222 and the third limiting part 113 are engaged, the upper surface of the deceleration mechanism 22 and the front side of the upper surface are pre-installed with the outer cover 11. This can save the assembly time between the deceleration mechanism 22 and the outer cover 11, and can also ensure the stability of the assembly between the deceleration mechanism 22 and the outer cover 11.

[0042] Optionally, such as Figures 7-10As shown, the third limiting part 113 is one of the limiting protrusion and the limiting groove, and the fourth limiting part 222 is the other of the limiting protrusion and the limiting groove. The limiting protrusion is disposed in the limiting groove. For example, the third limiting part 113 is a limiting protrusion and the fourth limiting part 222 is a limiting groove. The limiting protrusion can be engaged in the limiting groove, which facilitates the pre-installation of the deceleration mechanism 22 on the inner side of the outer cover 11, thereby saving the assembly time between the deceleration mechanism 22 and the outer cover 11. Alternatively, the third limiting part 113 can be a limiting groove and the second limiting part 221 can be a limiting protrusion, which also facilitates the pre-installation between the deceleration mechanism 22 and the outer cover 11.

[0043] In addition, such as Figures 9-11 As shown, the reduction mechanism 22 includes: a mounting shell 223 and a plurality of reduction gears 224. The mounting shell 223 is provided with a second limiting part 221 and a fourth limiting part 222. The mounting shell 223 is mounted on the outer cover 11 by fasteners 3. The plurality of reduction gears 224 mesh sequentially. The gear located at the first end is provided on the driving member 21, and the gear located at the tail end is provided on the transmission mechanism 23.

[0044] In other words, the mounting shell 223 and multiple reduction gears 224 constitute the reduction mechanism 22. The driving force of the drive member 21 is reduced by multiple reduction gears 224 and then transmitted to the transmission mechanism 23. The transmission mechanism 23 drives the front panel 12 to move. A second limiting part 221 is provided on the side of the mounting shell 223 away from the drive member 21. The second limiting part 221 is in a limiting cooperation with the first limiting part 112. This allows the mounting shell 223 to be pre-installed on the support part 111. The fourth mounting part is located on the upper surface of the mounting shell 223. The fourth limiting part 222 and the third limiting part 113 are in a limiting cooperation. This allows the mounting shell 223 to be pre-installed on the inner side of the outer cover 11, thereby saving the assembly time between the reduction mechanism 22 and the outer cover 11.

[0045] The fastener 3 is located on the lower side of the mounting shell 223. After the first limiting part 112 and the second limiting part 221 are engaged, and after the third limiting part 113 and the fourth limiting part 222 are engaged, the fastener 3 passes through the outer cover 11. This allows the mounting shell 223 to be firmly installed on the outer cover 11, thereby ensuring the stability of the mounting shell 223.

[0046] Multiple reduction gears 224 are connected between the drive component 21 and the transmission mechanism 23. The driving force of the drive component 21 is transmitted to the multiple reduction gears 224. The reduction gears 224 reduce the driving force and increase the transmission torque of the driving force. The reduced force is then transmitted to the transmission mechanism 23, which in turn drives the front panel 12 to move. For example, each set of reduction gears 224 consists of two gears meshing together, which ensures the effective transmission of force between the gears.

[0047] The driving force of the drive component 21 is transmitted through the gear at the beginning and the gear at the end. The gear at the end then transmits the driving force to the transmission mechanism 23 and the transmission rod. The two gears reduce the driving force and increase the transmission torque. This allows the use of the drive component 21 with lower power consumption, and also reduces the size of the transmission mechanism 23. This ensures that the front panel 12 can move relative to the outer cover 11, allowing for uniform air intake of the wall-mounted air conditioner indoor unit 100, thus facilitating air circulation in the wall-mounted air conditioner indoor unit 100. For example, two meshing gears form a two-stage reduction. The two meshing gears have the characteristics of compact structure, high space utilization, smooth transmission, high transmission efficiency, controllable loss, reasonable load distribution, and long service life.

[0048] Optionally, the plurality of reduction gears 224 include: a meshing first gear and a second gear, and meshing third gear and a fourth gear, the first gear being disposed on the drive member 21, the third gear rotating synchronously with the second gear, and the fourth gear being connected to the transmission mechanism 23.

[0049] It is understandable that the first gear, second gear, third gear and fourth gear are connected in sequence. The driving force of the driving component 21 is transmitted to the first gear. The second gear and the third gear rotate synchronously. After the first gear transmits the driving force to the second gear, the driving force undergoes a first-stage reduction. The driving force is then transmitted to the fourth gear through the third gear. The driving force undergoes a second-stage reduction. Finally, the fourth gear transmits the driving force with increased transmission torque to the transmission mechanism 23, so that the transmission mechanism 23 can drive the front panel 12 to move relative to the outer cover 11.

[0050] The third gear is located on one side of the second gear, and the third gear and the second gear are configured as a double gear. The driving force of the driving component 21 is transmitted to the first gear, and the first gear then transmits the driving force to the double gear. After reduction, the double gear transmits the force to the fourth gear, thus forming a two-stage reduction. The double gear can simplify the transmission chain, improve transmission efficiency, reduce assembly errors, make the transmission smoother, ensure transmission torque, reduce the number of parts, and reduce costs.

[0051] Specifically, the fourth gear is constructed as an incomplete gear and is integrally formed at one end of the rocker arm. For example, the fourth gear is a sector gear that meshes with the third gear, thereby enabling the third and fourth gears to be connected in a transmission manner. The fourth gear is located at the end of the rocker arm closer to the third gear, which allows the fourth gear to limit the range of motion of the rocker arm, thereby limiting the range of motion of the front panel 12 relative to the outer cover 11.

[0052] Among them, such as Figures 9-11As shown, the mounting housing 223 includes a main housing 225 and a cover plate 226. One side of the main housing 225 is open. Multiple reduction gears 224 are disposed inside the main housing 225. The main housing 225 is provided with a second limiting part 221 and a fourth limiting part 222. The main housing 225 is mounted to the outer cover 11 by fasteners 3. The cover plate 226 is disposed on one side of the main housing 225. The driving member 21 is disposed on the side of the cover plate 226 away from the main housing 225.

[0053] It is understood that the main shell 225 and the cover plate 226 constitute the main structure of the mounting shell 223. An opening is formed on one side of the main shell 225, which facilitates the installation of multiple reduction gears 224 in the mounting shell 223. The mounting shell 223 can protect the multiple reduction gears 224, thereby preventing them from being bumped by other components and extending their service life. The cover plate 226 covers the opening of the main shell 225. The drive member 21 and the cover plate 226 are located on the left and right sides of the main shell 225, which can form a certain receiving cavity between the main shell 225 and the cover plate 226. The receiving cavity can accommodate multiple reduction gears 224, thereby facilitating the deceleration of the driving force of the drive member 21 through the multiple reduction gears 224.

[0054] A second limiting part 221 is provided on the side of the main housing 225 away from the drive component 21. The second limiting part 221 is in a limiting cooperation with the first limiting part 112, so that the main housing 225 can be pre-installed on the support part 111. The fourth mounting part is located on the upper surface of the main housing 225. The fourth limiting part 222 and the third limiting part 113 are in a limiting cooperation, so that the main housing 225 can be pre-installed on the inner side of the outer cover 11, thereby saving the assembly time between the reduction mechanism 22 and the outer cover 11.

[0055] The fastener 3 is located on the lower side of the main shell 225. After the first limiting part 112 and the second limiting part 221 are engaged, and after the third limiting part 113 and the fourth limiting part 222 are engaged, the fastener 3 passes through the outer cover 11. This allows the main shell 225 to be firmly installed on the outer cover 11, thereby ensuring the stability of the main shell 225.

[0056] In addition, the wall-mounted air conditioner indoor unit 100 also includes a filter screen, which is installed inside the outer cover 11 and located between the air inlet 13 and the indoor heat exchanger, so as to filter the air entering from the air inlet 13.

[0057] Understandably, the filter is located inside the outer cover 11 and at the air inlet 13. The filter can filter the dust and impurities entering from the air inlet 13, thereby effectively filtering the dust and other particulate matter drawn in from the air inlet 13, which can directly improve the cleanliness of the air blown into the room, thus helping to improve indoor air quality.

[0058] Optionally, the reduction mechanism 22 includes a planetary gear reduction mechanism 22. A part of the transmission mechanism 23 is connected to the reduction mechanism 22, and the other part of the transmission mechanism 23 is connected to the front panel 12. The power transmission of the drive component 21 passes through the reduction mechanism 22, the transmission mechanism 23, and the front panel 12 in sequence. The reduction mechanism 22 increases the torque of the driving force, so that the drive component 21 with lower power consumption can be used for driving. It can also reduce the size of the transmission mechanism 23, ensuring that the front panel 12 can move relative to the outer cover 11, thereby facilitating the air circulation of the wall-mounted air conditioner indoor unit 100. For example, the planetary gear reduction mechanism 22 has the characteristics of high efficiency, high precision, large load capacity, small size, low noise, and long service life.

[0059] The sun gear, planet carrier, planet gears and ring gear constitute the main body of the planetary gear reduction mechanism 22. The sun gear is located at the center of the planetary gear reduction mechanism 22. The sun gear is connected to the driving member 21. The driving force of the driving member 21 can be transmitted to the sun gear. Then the sun gear rotates at high speed around its own central axis, that is, the sun gear rotates on its own axis, thereby continuing to transmit the driving force.

[0060] The planet carrier is connected to the transmission mechanism 23. The planet gears are located on the planet carrier. The planet carrier can ensure the stability of the force. The planet gears mesh with the sun gear for transmission. The planet carrier drives the planet gears to revolve around the sun gear, and the planet gears also rotate on their own axes, thus forming a dual motion. This allows the planet gears to decelerate the force. The driving force of the drive component 21 is transmitted to the sun gear, and the sun gear then transmits the force to the planet gears. The planet gears increase the torque of the force transmission and then transmit it to the planet carrier and the transmission mechanism 23 in sequence.

[0061] The gear ring is fixed inside the outer cover 11 and is located on the outer circumference of the planetary gears. The gear ring meshes with the planetary gears, which allows the gear ring to provide a reaction force to the planetary gears, forcing the planetary gears to revolve while rotating on their own axis. This allows the planetary gears to achieve a deceleration effect on the force, thereby increasing the transmission torque of the force transmitted from the drive component 21 to the transmission mechanism 23 by the sun gear, planet carrier, planetary gears, and gear ring. This allows the use of a low-power drive component 21, reducing the power consumption of the drive component 21 and thus reducing the energy consumption of the wall-mounted air conditioner indoor unit 100.

[0062] An air conditioner includes an indoor unit and an outdoor unit, which are connected by pipes to transfer 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 in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve the cooling or heating mode of the cabinet air conditioner. The compressor is configured to compress the refrigerant, so that the low-pressure refrigerant is compressed into high-pressure refrigerant.

[0063] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of a cabinet air conditioner, the outdoor heat exchanger functions as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the cabinet air conditioner, the outdoor heat exchanger functions as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0064] In some embodiments, the outdoor heat exchanger further includes fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0065] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet 13 and discharge the outdoor air, after heat exchange with the outdoor heat exchanger, through the outdoor air outlet 14. The outdoor fan provides power for the flow of outdoor air.

[0066] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening degree is adjustable to control the refrigerant flow rate and pressure.

[0067] 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 can perform cooling mode or heating mode.

[0068] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of a cabinet air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate. In the heating mode of the cabinet air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0069] In some embodiments, the indoor heat exchanger further includes fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0070] The indoor fan is configured to draw indoor air into the indoor unit through the third air inlet 13, and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the fourth air outlet 14. The indoor fan provides power for the flow of indoor air.
