Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a wall-mounted air conditioner indoor unit. Background Technology

[0002] Household air conditioning units can be divided into two types based on their structure: modular air conditioners and split-type air conditioners. Among them, split-type air conditioners commonly include cabinet air conditioners and wall-mounted air conditioners. Wall-mounted air conditioners are widely popular because of their compact structure and ability to save floor space.

[0003] The indoor casing of a wall-mounted air conditioner contains a heat exchanger, filter, and motor. The motor drives a cross-flow fan to rotate, which blows air out of the indoor unit, creating a negative pressure difference. Air from the room enters the indoor unit through the upper grille, passes through the filter, exchanges heat with the heat exchanger, and is then blown out through the air outlet, thus circulating the cycle. The filter, by filtering dust from the air, provides clean air and also protects the air conditioner.

[0004] In existing technologies, the air intake at the top of the casing has limited air volume. Some wall-mounted air conditioners employ a design with a movable front panel, which uses a drive assembly to open the front of the casing to supplement air intake, effectively increasing the air volume. However, this requires installing a motor into the drive assembly, which presents challenges in terms of installation convenience and instability. Utility Model Content

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-12 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0022] Reference Figures 1-5 As shown, the wall-mounted air conditioner indoor unit 100 of this utility model embodiment 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 111 and an air outlet 112. The air inlet 111 can be located at the top of the outer cover 11, and the air outlet 112 can be located at the bottom front side of the outer cover 11. The setting of the air inlet 111 can facilitate the intake of indoor air, and the air outlet 112 blows the processed air back into the room, thus effectively forming air circulation.

[0023] The front panel 12 is movably disposed on the front side of the outer cover 11. When the front panel 12 is in the closed position, it covers the front side of the outer cover 11 and blocks the air outlet 112. When the front panel 12 is in the open position, it opens the front side of the outer cover 11, allowing the indoor space to take in air from the front side of the outer cover 11, thereby providing supplemental air and increasing the air intake volume to meet the current air intake requirements. It also exposes the entire air outlet 112, thereby increasing the air supply range and preventing the front panel 12 from obstructing the airflow of the air outlet 112.

[0024] Furthermore, the indoor heat exchanger is housed within the outer casing 11, which provides both protection and a mounting location for the indoor heat exchanger. Located between the air inlet 111 and the air outlet 112, the indoor heat exchanger exchanges heat with the air entering through the air inlet 111. This results in a more uniform air temperature after passing through the indoor heat exchanger, preventing localized overcooling or overheating and improving the uniformity of the indoor temperature field. Further, the drive assembly 2 is housed within the outer casing 11 and is connected to the front panel 12. The drive assembly 2 provides power to the front panel 12, allowing it to selectively open and close the front side of the outer casing 11.

[0025] Furthermore, the drive assembly 2 includes: a mounting housing 20, a drive component 21, a reduction mechanism 22, and a transmission mechanism 23. The drive component 21 is disposed outside the mounting housing 20. The drive component 21 can be configured as a stepper motor, which makes reasonable use of the space outside the mounting housing 20 and avoids interference between the drive component 21 and other parts. The reduction mechanism 22 is disposed within the mounting housing 20. The mounting housing 20 provides housing space for the reduction mechanism 22 and also protects the reduction mechanism 22, thereby preventing dust from entering.

[0026] Furthermore, the reduction mechanism 22 is connected to the drive component 21, so that the drive component 21 can drive the reduction mechanism 22 to move, thereby outputting the required working speed. The transmission mechanism 23 is connected to both the reduction mechanism 22 and the front panel 12, so that the transmission mechanism 23 is located between the reduction mechanism 22 and the front panel 12. The reduction mechanism 22 can transmit power to the front panel 12 through the transmission mechanism 23, thereby facilitating the raising and lowering of the front panel 12.

[0027] The mounting shell 20 is provided with a first limiting part 201 and a first mounting hole 202, and the driving member 21 is provided with a second limiting part 211 and a second mounting hole 212. The first limiting part 201 and the second limiting part 211 are engaged in a circumferential limiting fit with the driving member 21. In this way, the circumferential positioning of the driving member 21 can be achieved, ensuring that there is no relative rotation between the driving member 21 and the mounting shell 20. Before the driving member 21 is fixed, it can also prevent the driving member 21 from falling off.

[0028] Furthermore, the mounting housing 20 is provided with a first limiting part 201, and the driving component 21 is provided with a second limiting part 211. When the first limiting part 201 and the second limiting part 211 are engaged in a circumferential upper limit engagement with the driving component 21, the first limiting part 201 and the second limiting part 211 can serve as installation guides for the driving component 21, helping operators to quickly align the driving component 21 and complete the initial positioning without rotation or adjustment. Further, the circumferential upper limit engagement of the first limiting part 201 and the second limiting part 211 ensures that the position (angular position) of the driving component 21 is consistent each time it is installed, thereby avoiding installation errors.

[0029] Furthermore, a fastener 24 is inserted into the first mounting hole 202 and the second mounting hole 212. The fastener 24 can be a screw, which can pass through the second mounting hole 212 and the first mounting hole 202. This can further fix the drive component 21 to the mounting shell 20, thereby making the drive component 21 more stable and securely fixed to the mounting shell 20.

[0030] Specifically, during installation, the drive component 21 first engages with the second limiting part 211 and the first limiting part 201 of the mounting shell 20 by rotating the drive component 21. Then, fasteners 24, such as screws, are sequentially inserted into the second mounting hole 212 of the drive component 21 and the first mounting hole 202 of the mounting shell 20 for fixing, which has the advantage of quick and accurate positioning and installation.

[0031] Therefore, the drive component 21 in the wall-mounted air conditioner indoor unit 100 can be accurately positioned and installed before fixing, and it can also ensure that there is no relative rotation between the drive component 21 and the mounting shell 20, and that the position of the drive component 21 remains unchanged. This makes the drive component 21 more stable and securely fixed on the mounting shell 20.

[0032] According to some embodiments of this utility model, such as Figures 5-10 As shown, the first limiting part 201 is configured as a limiting groove, with an opening on one side of the driving member 21 in the circumferential direction. The second limiting part 211 is configured as a limiting ear located on the outer periphery of the driving member 21, with the limiting ear disposed in the limiting groove.

[0033] The first limiting part 201 is constructed as a limiting groove, and the second limiting part 211 extends into the limiting groove. This allows the second limiting part 211 to be press-fitted with the limiting groove, thereby restricting its movement. Furthermore, the second limiting part 211 is constructed as a limiting ear located on the outer periphery of the driving member 21. The limiting groove can serve as a mounting track for the limiting ear, guiding it along a predetermined path and preventing it from shifting, wobbling, or jamming.

[0034] Moreover, the limiting ear is enclosed in the limiting groove, which can form a physical constraint. Even if the fastener 24 is loose or subjected to external impact, the limiting ear will not completely detach, thereby preventing the drive component 21 from detaching from the mounting shell 20. This is especially suitable for high-frequency operation or vibration environments.

[0035] According to some embodiments of this utility model, such as Figures 5-10 As shown, the outer periphery of the driving member 21 is provided with an outwardly protruding mounting ear 213, the mounting ear 213 is provided with a second mounting hole 212, and the mounting ear 213 and the limiting ear are distributed at intervals in the circumferential direction of the driving member 21.

[0036] The drive component 21 has an outwardly protruding mounting ear 213 on its outer periphery. The mounting ear 213 bears the axial clamping force of the fastener 24 and can also increase the contact area between the mounting ear 213 and the mounting shell 20, thereby reducing the stress concentration between the fastener 24 and the mounting ear 213 and facilitating the fixed connection between the drive component 21 and the mounting shell 20.

[0037] Furthermore, the mounting ear 213 is provided with a second mounting hole 212. Thus, the fastener 24 can pass through the second mounting hole 212 of the mounting ear 213 of the drive member 21 and be fixedly connected to the mounting shell 20, thereby making the connection between the drive member 21 and the mounting shell 20 more stable and secure. Moreover, the mounting ear 213 and the limiting ear are spaced apart in the circumferential direction of the drive member 21, which avoids excessive local stress between the mounting ear 213 and the limiting ear, thus preventing damage to the mounting ear 213 and the limiting ear. Because the mounting ear 213 and the limiting ear are spaced apart in the circumferential direction of the drive member 21, the mounting ear 213 and the limiting ear do not interfere with each other, thereby improving the strength of the mounting ear 213 and the limiting ear.

[0038] According to some embodiments of this utility model, such as Figures 5-10 As shown, the limiting ear and mounting ear 213 are symmetrically distributed about the central axis of the driving member 21.

[0039] The mounting ears 213 are used to fix the drive component 21 (such as a stepper motor) to the mounting housing 20, and the limiting ears are used to limit the position of the drive component 21, thereby preventing the drive component 21 from moving. When the limiting ears and mounting ears 213 are symmetrical about the central axis of the drive component 21, the force on the drive component 21 is distributed on both sides of its central axis. The vibration, torque, and reaction force generated by the drive component 21 during operation can be symmetrically and evenly distributed. This can avoid the twisting of the mounting housing 20, loosening of the fasteners 24, or local stress concentration caused by force eccentricity, thereby improving the structural stability of the drive component 21.

[0040] Furthermore, the limiting ear and mounting ear 213 are symmetrically distributed about the central axis of the drive component 21. During the assembly process, the drive component 21 is easier to align, which can ensure that the output shaft of the drive component 21 and the reduction mechanism 22 maintain good coaxiality, reduce assembly errors, and improve transmission efficiency, thereby reducing noise and wear caused by misalignment.

[0041] Furthermore, the drive component 21 (motor) is the main source of vibration. Symmetrical positioning and symmetrical installation can form a balanced support point. The energy of vibration can be effectively canceled or dispersed symmetrically, which can also reduce the transmission of vibration to the whole unit. It can also reduce low-frequency resonance and noise during air conditioner operation, thereby improving quietness performance.

[0042] According to some embodiments of this utility model, such as Figures 5-12 As shown, the drive component 21 is provided with a drive shaft 214, which extends into the mounting housing 20 and is connected to the reduction mechanism 22. The drive shaft 214 is located behind the line connecting the center of the limiting ear and the center of the mounting ear 213.

[0043] The drive component 21 is equipped with a drive shaft 214, which is the torque output point. The drive shaft 214 passes through the drive shaft hole 206 of the mounting housing 20. The mounting ear 213 and the limiting ear are the fixed support points of the drive component 21. When the drive shaft 214 is located behind the line connecting the center of the limiting ear and the center of the mounting ear 213, the point of application of the torque is closer to the fixed support point. This reduces the cantilever length of the drive shaft 214 relative to the fixed support point, reduces the bending moment caused by rotational torque, and effectively prevents the drive component 21 from tilting and loosening due to long-term stress.

[0044] According to some embodiments of this utility model, the limiting ear and the mounting ear 213 have the same structure.

[0045] In injection molding (plastic parts) or stamping (metal bracket) processes, there is no need to create separate molds for the two ears with different functions, which can reduce the cost of mold development and maintenance.

[0046] Furthermore, since the limiting ear and the mounting ear 213 have the same structure, the load-bearing capacity, shear resistance and tensile strength of the limiting ear and the mounting ear 213 are consistent. Even if one ear (such as the mounting ear 213) bears the main load, the other ear (the limiting ear) has the same strength and can serve as a backup support. Under abnormal vibration or impact, the drive component 21 can be installed more stably.

[0047] Furthermore, the mounting ears 213 are symmetrically distributed on the circumference of the drive member 21. For example, two mounting ears 213 are symmetrically arranged with respect to the center of the drive member 21, and the two mounting ears 213 are at 180°, which can form two symmetrical mounting points, thereby making the drive member 21 more evenly stressed.

[0048] Furthermore, the outer periphery of the drive component 21 is provided with a plurality of mounting ears 213, which are spaced apart along the outer periphery of the drive component 21, thus forming a plurality of mounting points, thereby making the connection between the drive component 21 and the mounting shell 20 more stable and secure.

[0049] Furthermore, the limiting ears are symmetrically distributed on the circumference of the driving member 21. For example, two limiting ears are symmetrically arranged with respect to the center of the driving member 21, and the two limiting ears are at 180°. This can form two symmetrical limiting points, thereby ensuring that the position of the driving member 21 does not change.

[0050] Furthermore, the outer periphery of the driving component 21 is provided with multiple limiting ears, which are spaced apart along the outer periphery of the driving component 21, thus forming multiple limiting points, thereby preventing the driving component 21 from rotating before fixed installation.

[0051] According to some embodiments of this utility model, such as Figures 5-12 As shown, the mounting housing 20 is provided with a stop edge 203 on the outer periphery of the first mounting hole 202, and the stop edge 203 cooperates with the mounting ear 213.

[0052] The mounting shell 20 is provided with a stop edge 203 on the outer periphery of the first mounting hole 202. The stop edge 203 protrudes from the mounting shell 20 and is arc-shaped. Correspondingly, the outer periphery of the mounting ear 213 is arc-shaped. In this way, the stop edge 203 and the mounting ear 213 can be adapted to each other, so that the stop edge 203 and the mounting ear 213 can have a tight stop fit.

[0053] Furthermore, the stop edge 203 also serves a positioning function. Before fixing the drive component 21, it can be positioned by the stop edge 203, ensuring that the position of the drive component 21 remains consistent after each installation. Without the stop edge 203, too many screws would be used, which would not only make it inconvenient to disassemble the drive component 21 during later maintenance but also lead to screw waste. Moreover, over-tightening the screws could cause the mounting lug 213 to crack. Due to the design of the stop edge 203, the stop edge 203 limits the maximum tightening stroke of the screw, preventing pressure from being transmitted to other components even if the screw continues to be tightened.

[0054] Furthermore, the contact surface between the stop edge 203 and the mounting ear 213 provides visual or tactile feedback, allowing operators to perceive a "positioning feel," enabling blind installation in confined spaces or automated equipment. Additionally, the stop edge 203 is designed with an arc-shaped reinforcement structure. This enhances the housing strength around the first mounting hole 202 and resists vibration loosening or fatigue cracking during long-term use. When maintenance personnel disassemble and reinstall the drive component 21, they can quickly determine the screw installation depth using the stop edge 203 without additional measurement or tools. When tightening the screw through the mounting ear 213, over-tightening can be avoided, preventing damage to the mounting ear 213.

[0055] According to some embodiments of this utility model, such as Figures 5-12 As shown, the mounting housing 20 includes a main housing 204 and a cover plate 205. One side of the main housing 204 is open. The deceleration mechanism 22 is disposed inside the main housing 204. The main housing 204 is disposed on the housing 1. The cover plate 205 is disposed on one side of the main housing 204. The driving component 21 is disposed on the side of the cover plate 205 away from the main housing 204. The cover plate 205 is provided with a first limiting part 201 and a first mounting hole 202.

[0056] The mounting housing 20 mainly consists of a main housing 204 and a cover plate 205. One side of the main housing 204 is open, facilitating the installation of the reduction mechanism 22 within it. This also facilitates maintenance of the reduction mechanism 22 should it be damaged. Furthermore, the main housing 204 protects the reduction mechanism 22, preventing dust from entering and contaminating it. The open side of the main housing 204 allows for direct side or axial installation of the reduction mechanism 22 without requiring complete disassembly, supporting modular pre-assembly. During maintenance, the gear set can be quickly removed for replacement or lubrication.

[0057] Furthermore, the main housing 204 is disposed on the housing 1, and the housing 1 provides a mounting position for the main housing 204, thereby facilitating its installation. A cover plate 205 is disposed on one side of the main housing 204. After the reduction mechanism 22 is installed, the cover plate 205 can seal one side of the main housing 204, thus preventing foreign objects from entering the main housing 204. Additionally, the main housing 204 and the cover plate 205 form a closed cavity, making full use of the internal space. The drive component 21 is disposed on the side of the cover plate 205 away from the main housing 204, thus saving internal space in the main housing 204.

[0058] Furthermore, the cover plate 205 is provided with a first limiting part 201 and a first mounting hole 202. The first limiting part 201 can restrict the rotation of the drive component 21 before it is fixed, thereby ensuring the installation position of the drive component 21 and facilitating the fixed installation of the drive component 21, which has the advantage of saving effort during installation. Moreover, the cover plate 205 is provided with a first mounting hole 202, which makes it easy for screws to pass through the mounting ears 213 of the drive component 21 and the first mounting hole 202, thereby fixing the drive component 21 to the cover plate 205.

[0059] According to some embodiments of this utility model, such as Figures 5-12 As shown, the main housing 204 is provided with a third mounting hole, which is opposite to the second mounting hole 212, and the fastener 24 passes through the third mounting hole.

[0060] Specifically, the fastener 24 can be a screw, and the main housing 204 is provided with a third mounting hole, which allows the screw to pass through the second mounting hole 212 of the mounting ear 213 of the drive component 21, the first mounting hole 202 of the cover plate 205 and the third mounting hole of the main housing 204 in sequence, thereby making the connection between the drive component 21 and the mounting housing 20 more stable and firm.

[0061] According to some embodiments of this utility model, such as Figures 5-12 As shown, there are at least two drive components 2, with at least two drive components 2 spaced apart in the left-right direction, and a transmission rod is provided between the reduction mechanisms 22 of two adjacent drive components 2.

[0062] The number of drive components 2 can be set to two, and the transmission rod is connected between two adjacent drive components 2. The drive components 2 can be set to two, and the transmission rod is set between the two drive components 2 and extends in the left and right direction. In this way, one drive component 2 can transmit power to the other drive component 2 through the transmission rod. The other drive component 2 can rotate under the drive of one drive component 2 through the transmission rod. In this way, the two drive components 2 can share a drive, which can simplify the structure and reduce the number of parts.

[0063] Furthermore, at least two transmission mechanisms 23 are disposed on the transmission rod, and when the transmission rod rotates, it can transmit power to the transmission mechanisms 23. Since at least two transmission mechanisms 23 are connected to the front panel 12, the transmission mechanisms 23 can drive the front panel 12 to move up or down, thereby realizing the opening and closing of the front panel 12.

[0064] Furthermore, the reduction mechanism 22 includes multiple gears housed within a mounting housing 20, which provides mounting positions for the gears. The gears drive sequentially, with the first gear connected to the drive member 21, allowing the drive member 21 to rotate the first gear.

[0065] Furthermore, the transmission end is located on one side of the gear at the tail end, so that the gear at the tail end can transmit power to the transmission end, which can drive the transmission rod to rotate.

[0066] Furthermore, the transmission mechanism 23 includes a rocker arm and a panel connector, with a gear located at the tail end of the rocker arm. Thus, the gear at the tail end can also transmit power to the rocker arm simultaneously, thereby facilitating the rotation of the rocker arm.

[0067] Furthermore, a panel connector is disposed on the front panel 12, with one end of the panel connector connected to the other end of the rocker arm, and the other end of the panel connector slidably disposed on the housing 1. Specifically, the gear located at the tail end can transmit power to the rocker arm, which rotates under drive, causing the panel connector to move. Since the other end of the panel connector is slidably disposed on the housing 1, the front panel 12 on the front side of the housing 1 can be pulled up or down.

[0068] 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 casing 1, thereby facilitating air circulation in 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.

[0069] 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.

[0070] 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.

[0071] The gear ring is fixed inside the housing 1 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.

[0072] In addition, the wall-mounted air conditioner indoor unit 100 also includes a filter screen, which is installed inside the casing 1 and located between the air inlet 111 and the indoor heat exchanger, so as to filter the air entering from the air inlet 111.

[0073] Understandably, the filter is located inside the casing 1 and at the air inlet 111. The filter can filter dust and impurities entering through the air inlet 111, thereby effectively filtering dust and other particulate matter drawn in from the air inlet 111. This can directly improve the cleanliness of the air blown into the room, thus helping to improve indoor air quality.

[0074] The wall-mounted air conditioner indoor unit 100 includes: a casing 1, a heat exchanger, a fan, and a display device. The casing 1 is installed indoors and forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0075] The housing 1 is generally rectangular in shape. The housing 1 has a top and a bottom, which are opposite each other in the height direction (vertical direction). The left and right sides of the housing 1 are opposite each other in the length direction (horizontal direction), and the front and rear sides of the housing 1 are opposite each other in the thickness direction (front-back direction).

[0076] The housing 1 is located at the top of the room or in the upper space of the room. The front of the housing 1 faces the user and the rear of the housing 1 faces the wall, making it suitable for connection with the wall.

[0077] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.

[0078] The housing 1 may include an outer cover 11 and a front panel 12. The outer cover 11 has an air inlet 111 and an air outlet 112. The outer cover 11 is generally in the shape of a cuboid frame, and the front side of the outer cover 11 has a frame opening. The front panel 12 is located on the front side of the outer cover 11. The outer cover 11 and the front panel 12 are connected to form the housing 1.

[0079] The outer casing 11 has a heat exchange air duct inside. The heat exchange air duct is used to house and fix various components in the indoor unit of the air conditioner, which can prevent foreign objects from colliding with the various components inside the outer casing 11, thereby improving the reliability of the indoor unit of the air conditioner during transportation or installation.

[0080] The outer casing 11 has an air inlet 111. The air inlet 111 is connected to the heat exchange duct and serves as an inlet for external air to flow into the casing 1, allowing indoor air to enter the heat exchange duct through the air inlet 111.

[0081] The outer casing 11 has an air outlet 112. The air outlet 112 is connected to the heat exchange air duct and serves as the outlet for the heat exchange airflow inside the casing 1, allowing the airflow inside the heat exchange air duct to flow out through the air outlet 112.

[0082] The air inlet 111 can be located at the top of the outer casing 11. The air outlet 112 can be located at the bottom of the outer casing 11 and near the front side of the outer casing 11, that is, the air outlet 112 is located at the bottom front side of the outer casing 11. In this embodiment, when the wall-mounted air conditioner indoor unit 100 is working, the wall-mounted air conditioner indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0083] The air outlet 112 can be elongated and can extend along the length of the casing 1, which improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0084] In some embodiments of this application, the housing 1 may further include a base, which forms the rear side of the wall-mounted air conditioner indoor unit 100 and is adapted to be mounted on a wall. The rear side of the outer cover 11 is open, and the outer cover 11 covers the front side of the base and is connected to the base. A heat exchange air duct is defined between the outer cover 11 and the base. The outer cover 11, the base, and the front panel 12 together form the housing 1.

[0085] Furthermore, the air conditioner includes a wall-mounted indoor unit 100 and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit 100 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 air conditioner's cooling or heating mode. The compressor is configured to compress the refrigerant, thereby compressing the low-pressure refrigerant into a high-pressure refrigerant.

[0086] 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.

[0087] 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.

[0088] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet and expel the outdoor air, after it has been heated by the outdoor heat exchanger, through the outdoor air outlet. The outdoor fan provides power for the flow of outdoor air.

[0089] 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.

[0090] 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.

[0091] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the 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 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.

[0092] 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 the indoor air and the refrigerant. An indoor fan is configured to draw indoor air into the indoor unit through the air inlet 111 and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the air outlet 112 of the indoor unit. The indoor fan provides power for the flow of indoor air.
