Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, specifically to a wall-mounted air conditioner. Background Technology

[0002] Currently, most wall-mounted air conditioners are limited by size and weight, and their functions are relatively limited, usually only able to cool or heat indoor air. If users feel that the indoor air is stale or stuffy after running the air conditioner for a long time, the usual operation is to open the window for ventilation. This requires manually opening and closing the window, which is not only inconvenient, but also causes the cool or warm air to escape quickly through the window, affecting people's comfort.

[0003] Existing technologies include some fresh air conditioning systems that use a single motor to drive a fresh air fan and an exhaust fan synchronously. This allows the fresh air module to draw in fresh air from the outside, while the exhaust module expels indoor air. However, if the fan is dropped during transport, it can easily damage the motor. Therefore, there is still room for improvement. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wall-mounted air conditioner that reduces the probability of damage, has higher reliability, and operates with low noise.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0107] This application describes the structure of a wall-mounted air conditioner.

[0108] Before proceeding, let's introduce the structure of a common air conditioner. The most common type of air conditioner is the split-type air conditioner, which consists of an indoor unit and an outdoor unit. The indoor and outdoor units are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0109] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling device. The compressor, outdoor heat exchanger, throttling device, and indoor heat exchanger are connected in sequence to form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger, respectively, to achieve the air conditioner's cooling mode or heating mode.

[0110] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0111] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates 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 air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0112] In some embodiments, the outdoor heat exchanger further includes heat exchange 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.

[0113] The outdoor fan is configured to draw in outside air into the outdoor unit and expel the outdoor air, which has been heated by the outdoor heat exchanger, to the outside. The outdoor fan provides power for the flow of outdoor air.

[0114] A throttling device connects the outdoor and indoor heat exchangers. It regulates the refrigerant pressure flowing through both devices, thereby controlling the refrigerant flow rate between them. The flow rate and pressure of the refrigerant between the outdoor and indoor heat exchangers affect their heat exchange performance. The throttling device can be a throttling tube, an electronic valve, etc. When the throttling device is an electronic valve, its opening is adjustable to regulate the refrigerant flow rate and pressure.

[0115] In some designs, the air conditioner also includes a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform cooling mode or heating mode.

[0116] An indoor heat exchanger is configured to exchange heat between indoor air and a refrigerant transported within the indoor heat exchanger. In some embodiments, the indoor heat exchanger further includes heat exchange fins to increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0117] The heat exchange fan is configured to draw indoor air into the indoor unit and deliver the indoor air, after heat exchange with the indoor heat exchanger, into the room, providing power for the flow of indoor air.

[0118] Air conditioners also include a control unit, which is mainly used to control the compressor's operating frequency and the opening degree of the throttling device. Some control units can also control the speed of the outdoor fan and the heat exchange fan. The control unit is connected to the compressor, throttling device, outdoor fan, and heat exchange fan via data cables to transmit communication information.

[0119] The control device includes a processor, which may include a central processing unit (CPU), a 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-transitory computer-readable medium coupled to the control device.

[0120] Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), card, stick, or keyboard drive).

[0121] This utility model discloses a wall-mounted air conditioner, which is an indoor unit. Wall-mounted air conditioners are typically installed on a wall, for example, in the upper area of ​​an interior wall.

[0122] The following description, with reference to the accompanying drawings, describes a wall-mounted air conditioner 10000 according to some embodiments of the present invention.

[0123] Reference Figures 1-4 The wall-mounted air conditioner 10000 according to an embodiment of the present utility model includes: a main body 1000.

[0124] The main body 1000 includes: a housing 1, the interior of which forms a cavity V1. The housing 1 constitutes the overall external structure of the wall-mounted air conditioner 10000 and can play a protective role.

[0125] Typically, the casing 1 is a long, rectangular shell, with its length positioned horizontally, meaning it is mounted on the wall laterally. In some actual products, to facilitate the drainage of condensate, the casing 1 is mounted horizontally on the wall at a small angle to the horizontal plane.

[0126] The main body 1000 also includes an indoor heat exchanger 2, which is disposed within the accommodating cavity V1. As described above, the indoor heat exchanger 2 is a loop in the refrigerant circuit, through which refrigerant flows for cooling or heating the air flowing from the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 typically extends along the length of the casing 1. For example, the indoor heat exchanger 2 is a two-fold or three-fold heat exchanger, where each fold of the indoor heat exchanger 2 is a plate-like structure extending along the length.

[0127] The main body 1000 also includes a heat exchange fan 41. In this application, the heat exchange fan 41 can be a cross-flow fan, which has low noise and large air volume. Furthermore, the air velocity of the cross-flow fan is more evenly distributed along its axial direction, which is beneficial for increasing the air delivery distance and range. Moreover, using a cross-flow fan, and having it positioned along the length of the main body 1000, ensures that the driven airflow can pass through the entire indoor heat exchanger 2, guaranteeing a balanced heat exchange efficiency across all components of the indoor heat exchanger 2.

[0128] In some embodiments, the main body 1000 further includes a base 3, which is disposed within the accommodating cavity V1. The base 3 serves as an internal mounting support structure for the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. Specifically, a volute air duct V03 is formed on the base 3, and a heat exchange fan 41 is disposed within the volute air duct V03. After the indoor air enters the casing 1, it is guided by the volute air duct V03 to ensure that the resistance encountered by the indoor air when flowing through the indoor heat exchanger 2 is minimized.

[0129] The main body 1000 also includes a first motor 42, which is disposed in the accommodating cavity V1. The first motor 42 is used to drive the heat exchange fan 41 to rotate so that the air inside the air conditioner can exchange heat with the indoor space.

[0130] Please refer to this again. Figures 1-4 The casing 1 has a heat exchange air inlet 101 and a heat exchange air outlet 102. When the heat exchange fan 41 is running, it draws indoor air into the casing 1 through the heat exchange air inlet 101. After heat exchange with the indoor heat exchanger 2, the heat-exchanged air is sent to the room through the heat exchange air outlet 102.

[0131] This allows for the regulation of indoor ambient temperature. The indoor heat exchanger 2 can function as an evaporator, so that the heat exchange outlet 102 provides cooling airflow toward the indoor space, or the indoor heat exchanger 2 can function as a condenser, so that the heat exchange outlet 102 provides heating airflow toward the indoor space.

[0132] In this application, the heat exchange air inlet 101 is located above the heat exchange air outlet 102 in the height direction of the main body 1000, which facilitates air intake from above and air exhaust from below. In this application, the height direction of the main body 1000 is the vertical direction.

[0133] Understandably, the main unit 1000 is usually installed on the wall, and to avoid interfering with people's daily lives, it is typically hung at a high position. By setting the main unit 1000 to blow out heat exchange air from below, the blown heat exchange air is less likely to be blocked by the roof or ground. This results in less resistance and energy loss during the air blowing process, a wider air delivery range, and allows the heat exchange air to flow throughout the entire indoor space as quickly as possible, thus improving heat exchange efficiency.

[0134] Reference Figure 1 and Figure 2 The heat exchange air inlet 101 is located above the heat exchange air outlet 102. The heat exchange air inlet 101 can take in air from above, which can avoid taking in air from the heat exchange air outlet 102 and prevent the heat exchange air from being blown out of the heat exchange air outlet 102 and directly sucked into the heat exchange air inlet 101, thus reducing the process of heat exchange air idling without participating in the indoor heat exchange.

[0135] In some specific embodiments, the heat exchange air inlet 101 is located at the top of the housing 1, that is, in an area that the user cannot see. Hiding the heat exchange air inlet 101 can improve the aesthetic appearance.

[0136] In some embodiments, the heat exchange outlet 102 is located directly in front of the housing 1, that is, the heat exchange outlet 102 blows air towards the front of the main body 1000. It can be understood that the side of the main body 1000 connected to the wall is usually referred to as the back or rear side, and the side opposite to the rear side is referred to as the front side. Therefore, when the heat exchange outlet 102 is located directly in front of the housing 1, the air outlet is away from the wall, the airflow resistance is small, and the air delivery range is wide.

[0137] In some other embodiments, the heat exchange outlet 102 is located on the front side of the housing 1 and near the bottom. It can also be said that the heat exchange outlet 102 is located at the lower front corner of the housing 1. In this case, the heat exchange air blown out by the heat exchange outlet 102 flows forward and downward at the same time. This allows the heat exchange air to sink and fall on people or objects on the ground after being delivered a certain distance, so that people or objects on the ground can be in a comfortable indoor environment as soon as possible.

[0138] In this application, the heat exchange fan 41 is located on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 101. It can be understood that the heat exchange fan 41 is a power drive component that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotation, and it is also a power drive component for air supply.

[0139] By placing the heat exchange fan 41 on the side of the indoor heat exchanger 2 away from the heat exchange inlet 101, the aerodynamic force generated when the heat exchange fan 41 rotates can be evenly distributed. Part of it is distributed to the air inlet side, so that the air drawn in can overcome the wind resistance generated by the indoor heat exchanger 2 when it flows into the volute air duct V03. The other part is distributed to the air outlet side, so that the air after heat exchange can be transported a longer distance when it is blown out from the heat exchange outlet 102.

[0140] In this application, the first motor 42 is located at one end of the length of the main body 1000. This facilitates the installation and maintenance of the first motor 42, and the main body 1000 as a whole does not need to become excessively tall or thick due to the placement of the first motor 42. Here, the height direction of the main body 1000 is consistent with the vertical direction, and the thickness direction of the main body 1000 is consistent with the front-to-back direction.

[0141] Reference Figure 3 , Figure 5 and Figure 6 , Figure 13 and Figure 14 In this application, the wall-mounted air conditioner 10000 also includes a second motor 5, which is disposed in the accommodating cavity V1 and located at the other end of the length direction of the main body 1000.

[0142] In this way, the first motor 42 and the second motor 5 are located at both ends of the length direction of the main body 1000. On the one hand, the two motors are separated and far apart, resulting in less electromagnetic interference between them. On the other hand, the two motors are arranged at both ends of the length direction of the main body 1000, rather than in the thickness or height direction of the main body 1000, so that the main body 1000 of the wall-mounted air conditioner 10000 has a slender shape, and is thin and light.

[0143] Reference Figure 6 and Figure 14 The wall-mounted air conditioner 10000 also includes a fresh air fan 6, which is a centrifugal fan with axial air intake and radial air outlet. In the length direction of the main body 1000, the fresh air fan 6 is located on the side of the heat exchange fan 41 away from the first motor 42.

[0144] Reference Figure 6 and Figure 14 The wall-mounted air conditioner 10000 also includes an exhaust fan 7, which is a centrifugal fan with axial air intake and radial air outlet. The exhaust fan 7 and the fresh air fan 6 are arranged along the length of the main body 1000, and the exhaust fan 7 is located on the side of the heat exchange fan 41 away from the first motor 42. For example, the exhaust fan 7 can be located between the fresh air fan 6 and the heat exchange fan 41; or, for another example, the fresh air fan 6 can be located between the exhaust fan 7 and the heat exchange fan 41.

[0145] Among them, the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate synchronously when in operation.

[0146] Centrifugal fans are characterized by their compact structure, large air volume, and low noise. Furthermore, the fan noise decreases significantly as the speed decreases. Therefore, smaller centrifugal fans can be used for the fresh air fan 6 and exhaust fan 7 to meet the high air volume requirements. The low vibration and noise of centrifugal fans make them less likely to resonate with the indoor heat exchanger 2, effectively controlling the overall vibration and noise of the wall-mounted air conditioner 10000.

[0147] Both the fresh air fan 6 and the exhaust fan 7 are centrifugal fans, allowing for a more efficient arrangement of their airflow directions. Specifically, the fresh air fan 6 draws in air axially and exits radially, while the exhaust fan 7 draws in air axially and exits radially. The fresh air fan 6 and exhaust fan 7 draw in air from opposite ends, and then both are driven to exit radially. The flow paths of the fresh air and exhaust air do not need to overlap axially, and their paths do not need to intersect. This helps reduce the need for bends and turns in the fresh air and exhaust paths, reducing wind resistance and energy consumption, ensuring airflow, and lowering noise.

[0148] Reference Figure 7 and Figure 15 In some embodiments, the second motor 5 includes a stator 51 and a rotor 52, which together form the main body of the second motor 5. The stator 51 has wound coils that generate an alternating magnetic field when an alternating current is applied, causing the rotor 52 to rotate in the alternating magnetic field.

[0149] Optionally, the rotor section 52 can be a magnetic ring or a magnetic tile. A magnetic ring is preferred for the rotor section 52, as it reduces leakage flux loss, enhances magnetic flux, and improves the power output efficiency of the second motor 5. Furthermore, using a magnetic ring results in a more uniform magnetic field distribution, better anti-interference performance, and higher mechanical precision.

[0150] The second motor 5 is an external rotor motor, with the rotor portion 52 arranged around the outside of the stator portion 51 in the radial direction. Choosing an external rotor motor for the second motor 5 not only simplifies its structure but also allows for a larger diameter due to the rotor portion 52's radial arrangement around the stator portion 51. This results in greater torque and makes it suitable for low-speed, high-torque, and direct-drive applications. In other words, when the second motor 5 outputs power, a speed reducer is not needed for torque amplification, saving space occupied by a speed reducer.

[0151] In addition, the rotor section 52 is located radially outside the stator section 51, with a large heat dissipation area and good heat dissipation performance, which is beneficial to the stable operation of the second motor 5. Moreover, with this arrangement, the diameter of the second motor 5 can be controlled to be smaller, without encroaching on the airflow channel space.

[0152] Reference Figure 7 and Figure 15 The second motor 5 also includes a motor housing 531, which supports and protects the main body of the second motor 5. The motor housing 531 is fixedly connected to the rotor 52, so that the motor housing 531 and the rotor 52 rotate synchronously. In this way, the rotor 52 can be fixed by the motor housing 531, which facilitates connection with external structures.

[0153] Reference Figure 7 and Figure 15 The second motor 5 also includes an output shaft 532, which is fixedly connected to the motor housing 531, so that the output shaft 532, the motor housing 531 and the rotor 52 rotate synchronously.

[0154] Among them, one of the fresh air fan 6 and the exhaust fan 7 is mounted on the radial outside of the motor housing 531 and fixedly connected to the motor housing 531, while the other is connected to the output shaft 532. The second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate synchronously when in operation.

[0155] Reference Figure 5 and Figure 6 , Figure 13 and Figure 14 The wall-mounted air conditioner 10000 also includes: a fresh air volute 8, a fresh air duct V01 formed inside the fresh air volute 8, a fresh air fan 6 installed inside the fresh air volute 8, and a fresh air inlet 801 and a fresh air outlet 802 formed on the fresh air volute 8. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air volute 8 through the fresh air inlet 801, and allows outdoor air entering the fresh air volute 8 to enter the room through the fresh air outlet 802.

[0156] Reference Figure 5 and Figure 6 , Figure 13 and Figure 14 The wall-mounted air conditioner 10000 also includes: an exhaust volute 9, an exhaust duct V02 formed inside the exhaust volute 9, an exhaust fan 7 installed inside the exhaust volute 9, and an exhaust inlet 901 and an exhaust outlet 902 formed on the exhaust volute 9. The rotation of the exhaust fan 7 allows indoor air to enter the exhaust volute 9 through the exhaust inlet 901, and allows the indoor air entering the exhaust volute 9 to be exhausted to the outside through the exhaust outlet 902.

[0157] In this application, a fresh air module is constructed by a fresh air volute 8 and a fresh air fan 6. The fresh air fan 6 is installed inside the fresh air duct V01 and is used to drive airflow to be drawn in from the fresh air inlet 801 and discharged into the room through the fresh air outlet 802. The operation of the fresh air fan 6 provides the power for the flow of fresh air.

[0158] Therefore, by setting up a fresh air duct V01 in conjunction with a fresh air fan 6, when the indoor air is relatively polluted or the air quality is average, the fresh air fan 6 can drive relatively fresh outdoor air into the indoor environment to improve the indoor airflow environment.

[0159] In this application, the exhaust volute 9 and the exhaust fan 7 constitute an exhaust module. The exhaust fan 7 is installed inside the exhaust duct V02 and is used to drive airflow to be drawn in from the exhaust inlet 901 and discharged from the room through the exhaust outlet 902. The operation of the exhaust fan 7 provides the power for the flow of polluted air.

[0160] Therefore, by setting up exhaust duct V02 in conjunction with exhaust fan 7, when the indoor air is relatively polluted or the air quality is average, the exhaust fan 7 can draw away and exhaust the polluted airflow in the indoor space. After the indoor air volume is reduced, fresh air will be drawn in from the outside or from other rooms through doors and windows, thereby reducing the degree of indoor air pollution.

[0161] In this application, the second motor 5, the fresh air fan 6, the exhaust fan 7, the fresh air volute 8, and the exhaust volute 9 constitute a two-way ventilation assembly, which is installed within the main body 1000. The two-way ventilation assembly can provide fresh air to the room and exhaust indoor air to the outside.

[0162] It should be noted that the operating mode of the bidirectional ventilation component in the wall-mounted air conditioner 10000 can be set according to actual usage needs. In some embodiments, the bidirectional ventilation component can operate in both fresh air mode and exhaust mode simultaneously, that is, the fresh air duct V01 and the exhaust air duct V02 can be opened at the same time. While the indoor stale airflow flows to the outdoor space, the outdoor fresh airflow can also enter the indoor space. Through the combination of inlet and outlet airflow, the efficiency of airflow improvement in the indoor space is increased, thereby meeting the user's needs in a timely manner when the user urgently needs to exhaust or refresh the indoor air.

[0163] Furthermore, because it simultaneously exhausts indoor air to the outside and replenishes it with fresh outdoor air, maintaining a sufficient indoor air volume, it makes it easier to remove indoor air. For example, if there are irritating gases (such as gases released from home decoration materials), gas, or other gas leaks indoors, a two-way ventilation component can be set up to operate in both fresh air and exhaust modes simultaneously, achieving rapid air exchange. Compared to conventional fresh air structures that simply introduce fresh air, the two-way ventilation component of this application has a larger purification flow rate per unit time, higher ventilation efficiency, and faster purification effect.

[0164] Furthermore, the ventilation system avoids rapid airflow like opening a window, which could cause drastic temperature changes and discomfort for occupants due to sudden temperature fluctuations. Also, the main structure is positioned at a relatively high elevation, ensuring that ventilation points are not too close to people, thus preventing discomfort.

[0165] In other embodiments, the bidirectional ventilation component can selectively operate in either a fresh air mode or an exhaust mode. Specifically, when the bidirectional ventilation component is in fresh air mode, the exhaust mode is disabled, and only the fresh air duct V01 is ventilated, while the exhaust duct V02 is not. Alternatively, when the bidirectional ventilation component is in exhaust mode, the fresh air mode is disabled, and the fresh air duct V01 is not ventilated, while the exhaust duct V02 is ventilated.

[0166] In some embodiments, the accommodating cavity V1 within the main body 1000 is divided into a first chamber V11 and a second chamber V12, as shown by the dashed box in the figure. The indoor heat exchanger 2 is located in the first chamber V11, and the bidirectional ventilation assembly is at least partially located in the second chamber V12. The heat exchange air inlet 101 and heat exchange air outlet 102 on the casing 1 are provided corresponding to the first chamber V11, and the casing air inlet 103 and casing air outlet 105 on the casing 1 are provided corresponding to the second chamber V12.

[0167] This configuration divides the accommodating cavity V1 into a first chamber V11 and a second chamber V12. The airflow inside the second chamber V12 is not affected by the heat exchange fan 41. The exhaust air inlet 901 can directly draw air from the second chamber V12. There is no need to connect the housing air inlet 103 and the exhaust air inlet 901 with a pipe, which not only reduces the space occupied by the pipe, but also allows for flexible selection of the position of the housing air inlet 103.

[0168] In some embodiments, refer to Figures 1-3 The air inlet 103 is located on the top wall of the main body 1000. Since the wall-mounted air conditioner 10000 is hung high on the wall, the air inlet 103 on the top wall of the main body 1000 is not easily seen, thus maintaining the aesthetic appearance of the main body 1000. A first ventilation duct V04 is formed between the air inlet 103 and the exhaust air inlet 901. The exhaust fan 7 rotates, drawing indoor air from the air inlet 103 into the first ventilation duct V04, and then through the exhaust air inlet 901 into the exhaust volute 9.

[0169] Among them, reference Figure 6 and Figure 7 , Figure 14 and Figure 15 In the fresh air volute 8 and the exhaust volute 9, the volute corresponding to the fan connected to the output shaft 532 has a mounting wall 12. The mounting wall 12 is arranged opposite to the output shaft 532. An elastic support member 13 is installed on the mounting wall 12. The end of the output shaft 532 away from the motor housing 531 is rotatably supported on the elastic support member 13.

[0170] Because the second motor 5 is an external rotor motor, and the axial dimension of an external rotor motor is relatively small, the distance between the two bearings inside the second motor 5 is also small. The effective support for the output shaft 532 can actually be considered as having only one support position. This leads to a decrease in the bending resistance of the output shaft 532, making it prone to resonance during high-speed rotation and resulting in increased vibration and noise. In particular, if it is dropped during transportation, it can easily damage the bearings, shortening the service life of the second motor 5.

[0171] In view of this, according to the wall-mounted air conditioner 10000 of this utility model embodiment, by providing an elastic support member 13 on the mounting wall 12, on the one hand, the end of the output shaft 532 away from the motor housing 531 can be supported, which is equivalent to increasing the support position of the output shaft 532, which can improve the installation reliability and stability of the output shaft 532 and reduce the probability of damage to the second motor 5. On the other hand, the elastic support member 13 can allow the output shaft 532 to undergo a certain degree of displacement, and absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation, which is beneficial to reduce the damage of the bearings in the second motor 5, extend the service life of the second motor 5, and also reduce the operating noise.

[0172] Reference Figure 7 and Figure 15 In some embodiments, the elastic support 13 includes a shock-absorbing pad 131, which is mounted on the mounting wall 12 and defines a receiving cavity 1311, the opening of which faces the motor housing 531.

[0173] The elastic support 13 includes a bushing 132, which is disposed within the receiving cavity 1311. During installation, the bushing 132 can be inserted into the receiving cavity 1311 through the opening. After installation, the bushing 132 is fixed inside the shock-absorbing pad 131, so that the shock-absorbing pad 131 is located between the bushing 132 and the mounting wall 12. The bushing 132 is sleeved on the outer side of the end of the output shaft 532 away from the motor housing 531, and the bushing 132 is rotatably engaged with the output shaft 532.

[0174] The assembly sequence of the shock-absorbing pad 131, bushing 132, and output shaft 532 can be as follows: first, the bushing 132 is placed on the outside of the output shaft 532, and then the output shaft 532 with the bushing 132 is inserted into the receiving cavity 1311 of the shock-absorbing pad 131; or, the bushing 132 is first embedded into the receiving cavity 1311 of the shock-absorbing pad 131, and then the end of the output shaft 532 away from the motor housing 531 is inserted into the bushing 132.

[0175] The damping pad 131 acts as a buffer, absorbing the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. This helps reduce bearing damage within the second motor 5, extends the service life of the second motor 5, and also reduces operating noise. The bushing 132 is located between the damping pad 131 and the output shaft 532, preventing the output shaft 532 from directly contacting the damping pad 131 during rotation, thus avoiding wear on the damping pad 131 and extending its service life.

[0176] Reference Figure 7 and Figure 15 In some embodiments, the outer peripheral surface of the bushing 132 is a convex spherical surface, and the inner peripheral surface of the receiving cavity 1311 includes a concave spherical surface 13111, which has the same shape as the convex spherical surface and fits into each other.

[0177] In this way, when the end of the output shaft 532 away from the motor housing 531 is slightly deflected or deformed, the bushing 132 will be slightly deflected relative to the damping pad 131 along with the output shaft 532, avoiding rigid constraint on the output shaft 532, which can further reduce the probability of damage to the bearings in the second motor 5, thereby extending the service life of the second motor 5.

[0178] Reference Figure 7 and Figure 15 In some embodiments, the inner peripheral surface of the receiving cavity 1311 further includes a guide surface 13112, which is located between the concave spherical surface 13111 and the opening of the receiving cavity 1311. The guide surface 13112 is formed as an annular surface, and the radial dimension of the annular surface gradually increases along the direction from the damping pad 131 to the stator portion 51.

[0179] During the process of installing the bushing 132 into the receiving cavity 1311 of the damping pad 131, the guide surface 13112 can play a guiding role, so that the bushing 132 can be installed into the receiving cavity 1311 more smoothly, which helps to improve assembly efficiency.

[0180] Reference Figure 7 and Figure 15 In some embodiments, the damping pad 131 has a first through hole 1312 on the side away from the motor housing 531, and the first through hole 1312 communicates with the receiving cavity 1311. By providing the first through hole 1312 on the side of the damping pad 131 away from the motor housing 531, the first through hole 1312 can vent air during the process of installing the bushing 132 into the damping pad 131, thereby allowing the bushing 132 to be installed more smoothly into the receiving cavity 1311 of the damping pad 131.

[0181] In this application, the mounting wall 12 defines a mounting groove 121 with an opening facing the second motor 5. The shock-absorbing pad 131 is installed in the mounting groove 121. The mounting groove 121 includes a bottom wall 1211 and a peripheral wall 1212. The bottom wall 1211 is disposed opposite to the second motor 5. The peripheral wall 1212 is connected to the side of the bottom wall 1211 facing the second motor 5 and surrounds the bottom wall 1211.

[0182] The bottom wall 1211 of the mounting groove 121 is provided with a second through hole 12111. By providing the second through hole 12111 in the bottom wall 1211 of the mounting groove 121, the second through hole 12111 can vent air during the installation of the shock-absorbing pad 131 into the mounting groove 121, so that the shock-absorbing pad 131 can be installed into the mounting groove 121 more smoothly.

[0183] In this application, the first through hole 1312 and the second through hole 12111 are arranged opposite to each other, and the first through hole 1312 connects the second through hole 12111 and the receiving cavity 1311. In the embodiment where the shock-absorbing pad 131 and the bushing 132 are assembled first and then installed into the mounting groove 121, by providing the first through hole 1312 on the side of the shock-absorbing pad 131 away from the motor housing 531, and providing the second through hole 12111 on the bottom wall 1211 of the mounting groove 121, the first through hole 1312 and the second through hole 12111 can vent air during the process of inserting the output shaft 532 into the bushing 132, thereby making the output shaft 532 insert into the bushing 132 more smoothly.

[0184] The diameters of the first through-hole 1312 and the second through-hole 12111 are both greater than 1 mm, for example, the diameters of the first through-hole 1312 and the second through-hole 12111 are 1.5 mm, 2 mm, 2.5 mm, etc. This arrangement is more conducive to venting.

[0185] The diameter of the first through hole 1312 is smaller than the maximum diameter of the bushing 132. This prevents the bushing 132 from coming out of the first through hole 1312 and also ensures the structural strength of the damping pad 131. The diameter of the second through hole 12111 is less than or equal to the diameter of the first through hole 1312. This ensures the structural strength of the mounting wall 12, improves the installation reliability of the elastic support 13, and thus improves the reliability of the second motor 5.

[0186] Reference Figure 12 In some embodiments, the damping pad 131 also has a plurality of damping cavities 1313 surrounding the receiving cavity 1311.

[0187] Therefore, by setting multiple damping cavities 1313, the position of the output shaft 532 relative to the mounting groove 121 can be adjusted, reducing the problem of misalignment between the central axis of the output shaft 532 and the central axis of the mounting groove 121 caused by assembly errors, as well as the problem of misalignment between the central axis of the output shaft 532 and the central axis of the mounting groove 121 caused by vibration during the operation of the second motor 5.

[0188] To improve the installation stability and reliability of the shock-absorbing pad 131 within the mounting groove 121, refer to Figure 12 The outer peripheral wall of the shock-absorbing pad 131 is provided with a plurality of protruding ribs 1314. The plurality of protruding ribs 1314 are arranged at intervals in the circumference of the shock-absorbing pad 131. Each protruding rib 1314 extends along the axial direction of the shock-absorbing pad 131. The protruding ribs 1314 can abut against the peripheral wall 1212 of the mounting groove 121, making the shock-absorbing pad 131 more firmly installed.

[0189] In this application, the end of the output shaft 532 away from the motor housing 531 can be configured to have a rounded corner, or the end of the output shaft 532 away from the motor housing 531 can be configured to be spherical. On the one hand, it is more convenient to insert the output shaft 532 into the bushing 132, and on the other hand, it can reduce the damage to the bushing 132 and other structures caused by the end of the output shaft 532 away from the motor housing 531.

[0190] Reference Figure 8 and Figure 9 In some embodiments, the end of the groove peripheral wall 1212 away from the groove bottom wall 1211 is provided with a snap-fit ​​part 12121. The snap-fit ​​part 12121 stops the shock absorber 131 on the side near the motor housing 531, thereby restricting the shock absorber 131 within the mounting groove 121, preventing the shock absorber 131 from falling out of the mounting groove 121, and ensuring the installation reliability and stability of the shock absorber 131.

[0191] In this application, there can be multiple snap-fit ​​parts 12121, which are arranged circumferentially at intervals around the opening of the mounting groove 121. The snap-fit ​​parts 12121 can be processed through the process holes 123 on the bottom wall 1211 of the groove, thus eliminating the need to add a slanted ejector mechanism in the mold, which helps to reduce the manufacturing cost of the mold.

[0192] Reference Figure 7 In some embodiments, the outer diameter of the elastic support 13 is D1, where D1 ≤ 60 mm and D1 ≥ 12 mm. For example, the outer diameter D1 of the elastic support 13 can be 12 mm, 20 mm, 30 mm, 40 mm, 50 mm, or 60 mm.

[0193] If the outer diameter D1 of the elastic support 13 is too small, the elastic support 13 cannot better absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. If the outer diameter D1 of the elastic support 13 is too large, it will result in the elastic support 13 occupying too much area, thereby affecting the structural strength of the mounting wall 12, or the area occupied by other structures on the mounting wall 12.

[0194] In the above technical solution, by limiting the outer diameter D1 of the elastic support member 13 to meet the above range, the elastic support member 13 can better provide elastic support for the end of the output shaft 532 away from the motor housing 531, while ensuring the structural strength of the mounting wall 12 and the area occupied by the other structures on the mounting wall 12. This reduces bearing damage in the second motor 5, extends the service life of the second motor 5, and also reduces operating noise.

[0195] Reference Figures 6-8 In some embodiments, the exhaust fan 7 is mounted on the radial outer side of the motor housing 531 and is fixedly connected to the motor housing 531, while the fresh air fan 6 is connected to the output shaft 532.

[0196] The second motor 5 is an external rotor motor, and the exhaust fan 7 is fitted on the radial outside of the motor housing 531. The second motor 5 is partially embedded in the exhaust fan 7 in the motor housing 531, and partially embedded in the fresh air fan 6 in the output shaft 532. This makes the second motor 5 almost overlap with the exhaust fan 7 and the fresh air fan 6 in the length direction of the main body 1000, so that the axial portion of the exhaust fan 7 and the fresh air fan 6 outside the second motor 5 is small. This makes the overall axial dimension of the bidirectional ventilation assembly close to the axial dimension of the second motor 5, thereby making the length dimension of the main body 1000 controllable.

[0197] Furthermore, because the second motor 5 uses an external rotor motor suitable for low-speed, high-torque, and direct-drive scenarios, a reducer is unnecessary. The exhaust fan 7 can be directly mounted radially outside the motor housing 531. This not only avoids increasing the overall axial dimension of the reducer but also avoids complicating the structural layout. Simply fixing the exhaust fan 7 to the motor housing 531 and connecting the fresh air fan 6 to the output shaft 532 of the second motor 5 allows the exhaust fan 7 and fresh air fan 6 to be coaxially stacked, enabling them to rotate synchronously with a small gap, eliminating the need for excessive spacing. This also ensures that the overall axial dimension of the bidirectional ventilation assembly is close to that of the second motor 5, and the length of the main body (1000mm) is controllable.

[0198] Reference Figure 6 and Figure 7The fresh air volute 8 defines a connected fan cavity V011 and an air inlet cavity V012. The fresh air fan 6 is located inside the fan cavity V011. The mounting wall 12 is formed on the fresh air volute 8 and is located between the fan cavity V011 and the air inlet cavity V012.

[0199] Combined Figure 8 and Figure 9 The mounting wall 12 is provided with an air passage 122, which surrounds the elastic support 13 and connects the fan cavity V011 and the air inlet cavity V012. The air passage 122 can be a ventilation opening 8211 extending along the thickness direction of the mounting wall 12. Multiple ventilation openings 8211 can be distributed around the elastic support 13, improving the space utilization of the mounting wall 12. The rotation of the fresh air fan 6 allows outdoor air to enter the air inlet cavity V012 through the fresh air inlet 801, pass through the air passage 122 into the fan cavity V011, and finally enter the room through the fresh air outlet 802.

[0200] Reference Figure 6 In some embodiments, the ratio of the outer diameter of the area where the air passage 122 is located to the outer diameter of the elastic support 13 is r1, where r1≤12 and r1≥3. Specifically, the outer diameter of the elastic support 13 is D1, the outer diameter of the area where the air passage 122 is located is D2, and the ratio r1 of D2 to D1 can be 3, 5, 7, 9, 11, or 12.

[0201] If the ratio r1 between the outer diameter of the area where the air passage 122 is located and the outer diameter of the elastic support 13 is too large, the elastic support 13 cannot better absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. If the ratio r1 between the outer diameter of the area where the air passage 122 is located and the outer diameter of the elastic support 13 is too small, it will easily affect the structural strength of the mounting wall 12 and the area occupied by the air passage 122 on the mounting wall 12, thereby affecting the air intake efficiency of the outdoor air.

[0202] In the above technical solution, by limiting the ratio r1 of the outer diameter of the area where the air passage 122 is located to the outer diameter of the elastic support member 13 to meet the above range, the elastic support member 13 can better provide elastic support for the end of the output shaft 532 away from the motor housing 531 while ensuring the structural strength of the mounting wall 12 and the air intake efficiency of the outdoor air. This reduces the damage to the bearings in the second motor 5, extends the service life of the second motor 5, and also reduces the operating noise.

[0203] Reference Figures 6-8 In some embodiments, the fresh air fan 6 is mounted on the radial outer side of the motor housing 531 and is fixedly connected to the motor housing 531, while the exhaust fan 7 is connected to the output shaft 532.

[0204] The fresh air volute 8 defines a connected fan cavity V011 and an air inlet cavity V012, which are connected by a vent 8211. A fresh air fan 6 is located within the fan cavity V011, and a mounting wall 12 is formed on the fresh air volute 8, positioned between the fan cavity V011 and the air inlet cavity V012. Rotation of the fresh air fan 6 allows outdoor air to enter the air inlet cavity V012 through the fresh air inlet 801, then enter the fan cavity V011 through the vent 8211, and finally enter the room through the fresh air outlet 802.

[0205] The second motor 5 is an external rotor motor, and the fresh air fan 6 is mounted on the radial outer side of the motor housing 531. The second motor 5 is partially embedded in the fresh air fan 6 within the motor housing 531, and partially embedded in the exhaust fan 7 within the output shaft 532. This makes the second motor 5 almost overlap with the exhaust fan 7 and the fresh air fan 6 in the length direction of the main body 1000, so that the portion of the exhaust fan 7 and the fresh air fan 6 outside the second motor 5 in the axial direction is small. This makes the overall axial dimension of the bidirectional ventilation assembly close to the axial dimension of the second motor 5, thereby making the length dimension of the main body 1000 controllable.

[0206] Furthermore, because the second motor 5 uses an external rotor motor suitable for low-speed, high-torque, and direct-drive scenarios, a reducer is unnecessary. The fresh air fan 6 can be directly mounted radially outside the motor housing 531. This not only avoids increasing the overall axial dimension of the reducer but also avoids complicating the structural layout. Simply fixing the fresh air fan 6 to the motor housing 531 and connecting the exhaust fan 7 to the output shaft 532 of the second motor 5 allows the exhaust fan 7 and fresh air fan 6 to be coaxially stacked, enabling them to rotate synchronously with a small gap, eliminating the need for excessive spacing. This also ensures that the overall axial dimension of the bidirectional ventilation assembly is close to that of the second motor 5, and the length of the main body (1000mm) is controllable.

[0207] Reference Figures 14-17 The exhaust volute 9 includes an exhaust end plate 91 and an exhaust enclosure plate 92. The exhaust end plate 91 is disposed opposite to the fresh air volute 8, and the exhaust enclosure plate 92 is connected between the exhaust end plate 91 and the fresh air volute 8.

[0208] The exhaust end plate 91 forms a mounting wall 12, and the exhaust inlet 901 is located on the mounting wall 12, surrounding the elastic support member 13. There can be multiple exhaust inlets 901 distributed around the elastic support member 13, improving the space utilization of the mounting wall 12, and thus improving the space utilization of the exhaust end plate 91. The rotation of the exhaust fan 7 allows indoor air to enter the exhaust volute 9 through the exhaust inlet 901, and then enter the outdoor environment through the exhaust outlet 902.

[0209] Reference Figure 14 and Figure 15 In some embodiments, the ratio of the outer diameter of the area where the exhaust air inlet 901 is located to the outer diameter of the elastic support 13 is r2, where r2≤12 and r2≥3.

[0210] Specifically, the outer diameter of the elastic support 13 is D1, the outer diameter of the area where the exhaust inlet 901 is located is D3, and the ratio r2 of D3 to D1 can be 3, 5, 7, 9, 11, or 12.

[0211] If the ratio r2 between the outer diameter of the area where the exhaust air inlet 901 is located and the outer diameter of the elastic support 13 is too large, the elastic support 13 cannot better absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. If the ratio r2 between the outer diameter of the area where the exhaust air inlet 901 is located and the outer diameter of the elastic support 13 is too small, it will easily affect the structural strength of the mounting wall 12 and the area occupied by the exhaust air inlet 901 on the mounting wall 12, thereby affecting the air intake efficiency of the room.

[0212] In the above technical solution, by limiting the ratio r2 of the outer diameter of the area where the exhaust air inlet 901 is located to the outer diameter of the elastic support 13 to meet the above range, it is possible to ensure the structural strength of the mounting wall 12 and the air intake efficiency of the indoor air, while enabling the elastic support 13 to better provide elastic support for the end of the output shaft 532 away from the motor housing 531, reduce bearing damage in the second motor 5, extend the service life of the second motor 5, and also reduce working noise.

[0213] Reference Figure 5 and Figure 13 In some embodiments, the fresh air volute 8 includes a first volute 81, which is located on the side of the exhaust volute 9 facing the heat exchange fan 41, and the first volute 81 is detachably connected to the exhaust volute 9.

[0214] The fresh air volute 8 also includes a second volute 82, which is located on the side of the first volute 81 facing the heat exchange fan 41, and the second volute 82 is detachably connected to the first volute 81. The first volute 81 is located between the exhaust volute 9 and the second volute 82.

[0215] In some embodiments, refer to Figures 5-6 , Figures 13-14The second volute 82 includes: a second volute half 821, which is located on the side of the first volute 81 facing the heat exchange fan 41 and is detachably connected to the first volute 81. The second volute half 821 has a vent 8211 at its center in the radial direction. A fan cavity V011 is formed between the second volute half 821 and the first volute 81. A fresh air fan 6 is located in the fan cavity V011, and the axial air inlet end of the fresh air fan 6 is set towards the vent 8211. The second volute half 821 and the first volute 81 surround a fresh air outlet 802.

[0216] The second volute 82 also includes a fan cover 822, which is located on the side of the second volute half 821 facing the heat exchange fan 41. The fan cover 822 is detachably connected to the second volute half 821. The cavity enclosed by the fan cover 822 and the second volute half 821 is the air inlet cavity V012. The fan cover 822 and the second volute half 821 enclose a fresh air inlet 801.

[0217] In one embodiment where the mounting wall 12 is formed in the fresh air volute 8, the second volute half 821 and the wall opposite to the fresh air fan 6 form the mounting wall 12.

[0218] With this configuration, an air intake cavity V012 is formed at the air intake end of the fresh air fan 6. The air intake cavity V012 formed in this way can cover the axial air intake end of the fresh air fan 6. The air intake cavity V012 can be used to contain air, so that air can enter the fresh air fan 6 vertically along the axial direction from the air intake cavity V012, thereby improving the air intake efficiency of the fresh air fan 6 and reducing air intake loss.

[0219] The fan shroud 822 is located on the side of the second volute half 821 facing the indoor heat exchanger 2, thus separating the fan cavity V011 from the indoor heat exchanger 2. When the indoor heat exchanger 2 is cooling, it absorbs heat from the air inlet cavity V012, gradually lowering the temperature of the fresh air. Because of the separation provided by the fan shroud 822, the indoor heat exchanger 2 is farther from the fan cavity V011, reducing the cooling capacity of the indoor heat exchanger 2 on the air inside the fan cavity V011, making it less likely for the air inside the fan cavity V011 to become overcooled and condensate.

[0220] In this way, even if the incoming fresh air is cooled, it will not become too cold and produce condensation. Furthermore, even if condensation occurs in the air intake cavity V012, the condensate tends to remain within V012 and is less likely to enter the fan cavity V011 and be blown into the room, thus preventing water from being blown out of the fresh air module. When the indoor heat exchanger 2 is heating, it absorbs the cold air from the air intake cavity V012, gradually increasing the temperature of the fresh air. The heated air then enters the fan cavity V011 and mixes thoroughly, resulting in warmer air being blown out of the fresh air module.

[0221] In some embodiments, at least one of the fresh air fan 6 and the exhaust fan 7 includes: a disc and blades connected to the disc, wherein the connection between the blades and the disc is provided with a transition rounded corner structure.

[0222] For example, specifically, such as Figure 7 and Figure 15 As shown, the exhaust fan 7 includes an exhaust wheel 71 and exhaust blades 72. The exhaust blades 72 are connected to the side of the exhaust wheel 71 away from the heat exchange fan 41, and there are multiple exhaust blades 72 arranged circumferentially. A rounded transition corner structure is provided at the connection between the exhaust blades 72 and the exhaust wheel 71. This reduces the concentrated stress at the connection between the exhaust blades 72 and the exhaust wheel 71, improving overall strength. Furthermore, when the airflow flows axially towards the exhaust wheel 71, the airflow can be guided by the rounded transition corner structure under pressure difference, resulting in less turbulence when the airflow changes direction, thus helping to reduce energy consumption.

[0223] For example, specifically, the fresh air fan 6 includes a fresh air impeller 61 and fresh air blades 62. The fresh air blades 62 are connected to the fresh air impeller 61, and there are multiple fresh air blades 62 arranged circumferentially. The connection between the fresh air blades 62 and the fresh air impeller 61 has a transition rounded corner structure. This can reduce the concentrated stress at the connection between the fresh air blades 62 and the fresh air impeller 61, and improve the overall strength. In addition, when the airflow flows axially towards the fresh air impeller 61, the airflow can be guided by the transition rounded corner structure under the drive of pressure difference, and flows more smoothly towards the fresh air blades 62, thereby helping to reduce energy consumption.

[0224] The outer diameter of the exhaust fan 7 is set to be smaller than that of the fresh air fan 6, which makes it easy to make the exhaust outlet 902 of the exhaust duct V02 and the fresh air outlet 802 of the fresh air duct V01 staggered on the outer periphery of the bidirectional ventilation component. This makes it convenient to connect the exhaust outlet pipe 142 to the exhaust outlet 902 and the fresh air inlet pipe 141 to the fresh air outlet 802. On the other hand, it makes it easy to ensure that the flow paths of fresh air and exhaust air in the bidirectional ventilation component do not cross.

[0225] In some embodiments, refer to Figure 5 and Figure 6 The wall-mounted air conditioner also includes a purification component 11, which is installed inside the air inlet cavity V012, so that the fresh air blown into the room is purified and the cleanliness of the indoor air is improved.

[0226] Specifically, the fresh air volute 8 is provided with an installation port 803, which communicates with the air inlet cavity V012. The purification component 11 can be installed in the air inlet cavity V012 through the installation port 803. The purification component 11 is located at the axial air inlet end of the fresh air fan 6. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air volute 8 from the fresh air inlet 801, and allows the outdoor air entering the fresh air volute 8 to be blown through the purification component 11 and then enter the room from the fresh air outlet 802.

[0227] In this way, the fresh airflow can blow almost vertically over the purification component 11, further reducing the consumption of fresh air intake and thus increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in cooling mode, causing condensation to form in the fresh air, the condensation can remain on the purification component 11 as the air flows through it, further preventing water from being blown out when the fresh air module exits.

[0228] Furthermore, the purification component 11 is connected to the second volute 82, which facilitates the assembly of the purification component 11 and prevents it from interfering with the fresh air fan 6.

[0229] The following description, with reference to the accompanying drawings, describes a wall-mounted air conditioner 10000 according to other embodiments of the present invention.

[0230] Reference Figures 1-4 The wall-mounted air conditioner 10000 according to an embodiment of the present utility model includes: a main body 1000.

[0231] The main body 1000 includes: a housing 1, the interior of which forms a cavity V1. The housing 1 constitutes the overall external structure of the wall-mounted air conditioner 10000 and can play a protective role.

[0232] Typically, the casing 1 is a long, rectangular shell, with its length positioned horizontally, meaning it is mounted on the wall laterally. In some actual products, to facilitate the drainage of condensate, the casing 1 is mounted horizontally on the wall at a small angle to the horizontal plane.

[0233] The main body 1000 also includes an indoor heat exchanger 2, which is disposed within the accommodating cavity V1. As described above, the indoor heat exchanger 2 is a loop in the refrigerant circuit, through which refrigerant flows for cooling or heating the air flowing from the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 typically extends along the length of the casing 1. For example, the indoor heat exchanger 2 is a two-fold or three-fold heat exchanger, where each fold of the indoor heat exchanger 2 is a plate-like structure extending along the length.

[0234] The main body 1000 also includes a heat exchange fan 41. In this application, the heat exchange fan 41 can be a cross-flow fan, which has low noise and large air volume. Furthermore, the air velocity of the cross-flow fan is more evenly distributed along its axial direction, which is beneficial for increasing the air delivery distance and range. Moreover, using a cross-flow fan, and having it positioned along the length of the main body 1000, ensures that the driven airflow can pass through the entire indoor heat exchanger 2, guaranteeing a balanced heat exchange efficiency across all components of the indoor heat exchanger 2.

[0235] In some embodiments, the main body 1000 further includes a base 3, which is disposed within the accommodating cavity V1. The base 3 serves as an internal mounting support structure for the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. Specifically, a volute air duct V03 is formed on the base 3, and a heat exchange fan 41 is disposed within the volute air duct V03. After the indoor air enters the casing 1, it is guided by the volute air duct V03 to ensure that the resistance encountered by the indoor air when flowing through the indoor heat exchanger 2 is minimized.

[0236] The main body 1000 also includes a first motor 42, which is disposed in the accommodating cavity V1. The first motor 42 is used to drive the heat exchange fan 41 to rotate so that the air inside the air conditioner can exchange heat with the indoor space.

[0237] Please refer to this again. Figures 1-4 The casing 1 has a heat exchange air inlet 101 and a heat exchange air outlet 102. When the heat exchange fan 41 is running, it draws indoor air into the casing 1 through the heat exchange air inlet 101. After heat exchange with the indoor heat exchanger 2, the heat-exchanged air is sent to the room through the heat exchange air outlet 102.

[0238] This allows for the regulation of indoor ambient temperature. The indoor heat exchanger 2 can function as an evaporator, so that the heat exchange outlet 102 provides cooling airflow toward the indoor space, or the indoor heat exchanger 2 can function as a condenser, so that the heat exchange outlet 102 provides heating airflow toward the indoor space.

[0239] In this application, the heat exchange air inlet 101 is located above the heat exchange air outlet 102 in the height direction of the main body 1000, which facilitates air intake from above and air exhaust from below. In this application, the height direction of the main body 1000 is the vertical direction.

[0240] Understandably, the main unit 1000 is usually installed on the wall, and to avoid interfering with people's daily lives, it is typically hung at a high position. By setting the main unit 1000 to blow out heat exchange air from below, the blown heat exchange air is less likely to be blocked by the roof or ground. This results in less resistance and energy loss during the air blowing process, a wider air delivery range, and allows the heat exchange air to flow throughout the entire indoor space as quickly as possible, thus improving heat exchange efficiency.

[0241] Reference Figure 1 and Figure 2 The heat exchange air inlet 101 is located above the heat exchange air outlet 102. The heat exchange air inlet 101 can take in air from above, which can avoid taking in air from the heat exchange air outlet 102 and prevent the heat exchange air from being blown out of the heat exchange air outlet 102 and directly sucked into the heat exchange air inlet 101, thus reducing the process of heat exchange air idling without participating in the indoor heat exchange.

[0242] In some specific embodiments, the heat exchange air inlet 101 is located at the top of the housing 1, that is, in an area that the user cannot see. Hiding the heat exchange air inlet 101 can improve the aesthetic appearance.

[0243] In some embodiments, the heat exchange outlet 102 is located directly in front of the housing 1, that is, the heat exchange outlet 102 blows air towards the front of the main body 1000. It can be understood that the side of the main body 1000 connected to the wall is usually referred to as the back or rear side, and the side opposite to the rear side is referred to as the front side. Therefore, when the heat exchange outlet 102 is located directly in front of the housing 1, the air outlet is away from the wall, the airflow resistance is small, and the air delivery range is wide.

[0244] In some other embodiments, the heat exchange outlet 102 is located on the front side of the housing 1 and near the bottom. It can also be said that the heat exchange outlet 102 is located at the lower front corner of the housing 1. In this case, the heat exchange air blown out by the heat exchange outlet 102 flows forward and downward at the same time. This allows the heat exchange air to sink and fall on people or objects on the ground after being delivered a certain distance, so that people or objects on the ground can be in a comfortable indoor environment as soon as possible.

[0245] In this application, the heat exchange fan 41 is located on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 101. It can be understood that the heat exchange fan 41 is a power drive component that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotation, and it is also a power drive component for air supply.

[0246] By placing the heat exchange fan 41 on the side of the indoor heat exchanger 2 away from the heat exchange inlet 101, the aerodynamic force generated when the heat exchange fan 41 rotates can be evenly distributed. Part of it is distributed to the air inlet side, so that the air drawn in can overcome the wind resistance generated by the indoor heat exchanger 2 when it flows into the volute air duct V03. The other part is distributed to the air outlet side, so that the air after heat exchange can be transported a longer distance when it is blown out from the heat exchange outlet 102.

[0247] In this application, the first motor 42 is located at one end of the length of the main body 1000. This facilitates the installation and maintenance of the first motor 42, and the main body 1000 as a whole does not need to become excessively tall or thick due to the placement of the first motor 42. Here, the height direction of the main body 1000 is consistent with the vertical direction, and the thickness direction of the main body 1000 is consistent with the front-to-back direction.

[0248] Reference Figure 3, Figures 18-21 In this application, the wall-mounted air conditioner 10000 also includes a second motor 5, which is disposed in the accommodating cavity V1 and located at the other end of the length direction of the main body 1000.

[0249] In this way, the first motor 42 and the second motor 5 are located at both ends of the length direction of the main body 1000. On the one hand, the two motors are separated and far apart, resulting in less electromagnetic interference between them. On the other hand, the two motors are arranged at both ends of the length direction of the main body 1000, rather than in the thickness or height direction of the main body 1000, so that the main body 1000 of the wall-mounted air conditioner 10000 has a slender shape, and is thin and light.

[0250] Reference Figure 18 and Figure 20 The wall-mounted air conditioner 10000 also includes a fresh air fan 6, which is a centrifugal fan with axial air intake and radial air outlet. In the length direction of the main body 1000, the fresh air fan 6 is located on the side of the heat exchange fan 41 away from the first motor 42.

[0251] Reference Figure 18 and Figure 20 The wall-mounted air conditioner 10000 also includes an exhaust fan 7, which is a centrifugal fan with axial air intake and radial air outlet. The exhaust fan 7 and the fresh air fan 6 are located along the length of the main body 1000, and the exhaust fan 7 is located on the side of the heat exchange fan 41 away from the first motor 42. For example, the exhaust fan 7 may be located between the fresh air fan 6 and the heat exchange fan 41; or, for another example, the fresh air fan 6 may be located between the exhaust fan 7 and the heat exchange fan 41.

[0252] Among them, the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate synchronously when in operation.

[0253] Centrifugal fans are characterized by their compact structure, large air volume, and low noise. Furthermore, the fan noise decreases significantly as the speed decreases. Therefore, smaller centrifugal fans can be used for the fresh air fan 6 and exhaust fan 7 to meet the high air volume requirements. The low vibration and noise of centrifugal fans make them less likely to resonate with the indoor heat exchanger 2, effectively controlling the overall vibration and noise of the wall-mounted air conditioner 10000.

[0254] Both the fresh air fan 6 and the exhaust fan 7 are centrifugal fans, allowing for a more efficient arrangement of their airflow directions. Specifically, the fresh air fan 6 draws in air axially and exits radially, while the exhaust fan 7 draws in air axially and exits radially. The fresh air fan 6 and exhaust fan 7 draw in air from opposite ends, and then both are driven to exit radially. The flow paths of the fresh air and exhaust air do not need to overlap axially, and their paths do not need to intersect. This helps reduce the need for bends and turns in the fresh air and exhaust paths, reducing wind resistance and energy consumption, ensuring airflow, and lowering noise.

[0255] Reference Figure 18 and Figure 20 The wall-mounted air conditioner 10000 also includes: a fresh air volute 8, a fresh air duct V01 formed inside the fresh air volute 8, a fresh air fan 6 installed inside the fresh air volute 8, and a fresh air inlet 801 and a fresh air outlet 802 formed on the fresh air volute 8. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air volute 8 through the fresh air inlet 801, and allows outdoor air entering the fresh air volute 8 to enter the room through the fresh air outlet 802.

[0256] Reference Figure 18 and Figure 20 The wall-mounted air conditioner 10000 also includes: an exhaust volute 9, an exhaust duct V02 formed inside the exhaust volute 9, an exhaust fan 7 installed inside the exhaust volute 9, and an exhaust inlet 901 and an exhaust outlet 902 formed on the exhaust volute 9. The rotation of the exhaust fan 7 allows indoor air to enter the exhaust volute 9 through the exhaust inlet 901, and allows the indoor air entering the exhaust volute 9 to be exhausted to the outside through the exhaust outlet 902.

[0257] In this application, a fresh air module is constructed by a fresh air volute 8 and a fresh air fan 6. The fresh air fan 6 is installed inside the fresh air duct V01 and is used to drive airflow to be drawn in from the fresh air inlet 801 and discharged into the room through the fresh air outlet 802. The operation of the fresh air fan 6 provides the power for the flow of fresh air.

[0258] Therefore, by setting up a fresh air duct V01 in conjunction with a fresh air fan 6, when the indoor air is relatively polluted or the air quality is average, the fresh air fan 6 can drive relatively fresh outdoor air into the indoor environment to improve the indoor airflow environment.

[0259] In this application, the exhaust volute 9 and the exhaust fan 7 constitute an exhaust module. The exhaust fan 7 is installed inside the exhaust duct V02 and is used to drive airflow to be drawn in from the exhaust inlet 901 and discharged from the room through the exhaust outlet 902. The operation of the exhaust fan 7 provides the power for the flow of polluted air.

[0260] Therefore, by setting up exhaust duct V02 in conjunction with exhaust fan 7, when the indoor air is relatively polluted or the air quality is average, the exhaust fan 7 can draw away and exhaust the polluted airflow in the indoor space. After the indoor air volume is reduced, fresh air will be drawn in from the outside or from other rooms through doors and windows, thereby reducing the degree of indoor air pollution.

[0261] In this application, the second motor 5, the fresh air fan 6, the exhaust fan 7, the fresh air volute 8, and the exhaust volute 9 constitute a two-way ventilation assembly, which is installed within the main body 1000. The two-way ventilation assembly can provide fresh air to the room and exhaust indoor air to the outside.

[0262] It should be noted that the operating mode of the bidirectional ventilation component in the wall-mounted air conditioner 10000 can be set according to actual usage needs. In some embodiments, the bidirectional ventilation component can operate in both fresh air mode and exhaust mode simultaneously, that is, the fresh air duct V01 and the exhaust air duct V02 can be opened at the same time. While the indoor stale airflow flows to the outdoor space, the outdoor fresh airflow can also enter the indoor space. Through the combination of inlet and outlet airflow, the efficiency of airflow improvement in the indoor space is increased, thereby meeting the user's needs in a timely manner when the user urgently needs to exhaust or refresh the indoor air.

[0263] Furthermore, because it simultaneously exhausts indoor air to the outside and replenishes it with fresh outdoor air, maintaining a sufficient indoor air volume, it makes it easier to remove indoor air. For example, if there are irritating gases (such as gases released from home decoration materials), gas, or other gas leaks indoors, a two-way ventilation component can be set up to operate in both fresh air and exhaust modes simultaneously, achieving rapid air exchange. Compared to conventional fresh air structures that simply introduce fresh air, the two-way ventilation component of this application has a larger purification flow rate per unit time, higher ventilation efficiency, and faster purification effect.

[0264] Furthermore, the ventilation system avoids rapid airflow like opening a window, which could cause drastic temperature changes and discomfort for occupants due to sudden temperature fluctuations. Also, the main structure is positioned at a relatively high elevation, ensuring that ventilation points are not too close to people, thus preventing discomfort.

[0265] In other embodiments, the bidirectional ventilation component can selectively operate in either a fresh air mode or an exhaust mode. Specifically, when the bidirectional ventilation component is in fresh air mode, the exhaust mode is disabled, and only the fresh air duct V01 is ventilated, while the exhaust duct V02 is not. Alternatively, when the bidirectional ventilation component is in exhaust mode, the fresh air mode is disabled, and the fresh air duct V01 is not ventilated, while the exhaust duct V02 is ventilated.

[0266] Among them, reference Figures 18-21The second motor 5 includes a motor body 50 and an output shaft 532. The output shaft 532 is connected to the motor body 50. The motor body 50 is located in one of the fresh air volute 8 and the exhaust volute 9. The other of the fresh air volute 8 and the exhaust volute 9 has a mounting wall 12. An elastic support member 13 is mounted on the mounting wall 12. The end of the output shaft 532 away from the motor body 50 is rotatably supported on the elastic support member 13.

[0267] In the above technical solution, by setting an elastic support 13 on the mounting wall 12, on the one hand, the end of the output shaft 532 away from the motor body 50 can be supported, which is equivalent to increasing the support position of the output shaft 532. This can improve the installation reliability and stability of the output shaft 532 and reduce the probability of damage to the second motor 5. On the other hand, the elastic support 13 can allow the output shaft 532 to undergo a certain degree of displacement. Through its own deformation, it can absorb the vibration and impact energy generated by the output shaft 532 during rotation, which is beneficial to reduce the damage of the bearings in the second motor 5, extend the service life of the second motor 5, and also reduce the operating noise.

[0268] The mounting wall 12 is provided with a ventilation section 122, which surrounds the elastic support 13. The ratio of the outer diameter of the area where the ventilation section 122 is located to the outer diameter of the elastic support 13 is r, where r≤12 and r≥3.

[0269] Specifically, the outer diameter of the elastic support 13 is D1, the outer diameter of the area where the air passage 122 is located is D, and the ratio r of D to D1 can be 3, 5, 7, 9, 11, or 12.

[0270] If the ratio r between the outer diameter of the area where the air passage 122 is located and the outer diameter of the elastic support 13 is too large, the elastic support 13 will not be able to better absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. If the ratio r between the outer diameter of the area where the air passage 122 is located and the outer diameter of the elastic support 13 is too small, it will easily affect the structural strength of the mounting wall 12 and the area occupied by the air passage 122 on the mounting wall 12, thereby affecting the air intake efficiency.

[0271] In the above technical solution, by limiting the ratio r between the outer diameter of the area where the air passage 122 is located and the outer diameter of the elastic support 13 to meet the above range, the elastic support 13 can better provide elastic support to the end of the output shaft 532 away from the motor body 50 while ensuring the structural strength of the mounting wall 12 and the air intake efficiency. This reduces bearing damage in the second motor 5, extends the service life of the second motor 5, and also reduces operating noise.

[0272] Reference Figures 6-7 , Figure 14 and Figure 15In some embodiments, the second motor 5 can be an external rotor motor. The motor housing 531 of the second motor 5 rotates synchronously with the output shaft 532. One of the motor housing 531 and the output shaft 532 is connected to the fresh air fan 6, and the other is connected to the exhaust fan 7. When the second motor 5 is running, it can drive the fresh air fan 6 and the exhaust fan 7 to rotate synchronously.

[0273] Reference Figures 18-21 In some embodiments, the second motor 5 is an internal rotor motor. The output shaft 532 of the second motor 5 is connected to the fresh air fan 6 and the exhaust fan 7. When the second motor 5 is running, it can drive the fresh air fan 6 and the exhaust fan 7 to rotate synchronously.

[0274] Reference Figure 19 and Figure 21 In some embodiments, the elastic support 13 includes a shock-absorbing pad 131, which is mounted on the mounting wall 12 and defines a receiving cavity 1311 with an opening facing the motor body 50.

[0275] The elastic support 13 includes a bushing 132, which is disposed within the receiving cavity 1311. During installation, the bushing 132 can be inserted into the receiving cavity 1311 through the opening. After installation, the bushing 132 is fixed inside the shock-absorbing pad 131, so that the shock-absorbing pad 131 is located between the bushing 132 and the mounting wall 12. The bushing 132 is sleeved on the outer side of the end of the output shaft 532 away from the motor body 50, and the bushing 132 is rotatably engaged with the output shaft 532.

[0276] The assembly sequence of the shock-absorbing pad 131, bushing 132, and output shaft 532 can be as follows: first, the bushing 132 is placed on the outside of the output shaft 532, and then the output shaft 532 with the bushing 132 is inserted into the receiving cavity 1311 of the shock-absorbing pad 131; or, the bushing 132 is first embedded into the receiving cavity 1311 of the shock-absorbing pad 131, and then the end of the output shaft 532 away from the motor body 50 is inserted into the bushing 132.

[0277] The damping pad 131 acts as a buffer, absorbing the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. This helps reduce bearing damage within the second motor 5, extends the service life of the second motor 5, and also reduces operating noise. The bushing 132 is located between the damping pad 131 and the output shaft 532, preventing the output shaft 532 from directly contacting the damping pad 131 during rotation, thus avoiding wear on the damping pad 131 and extending its service life.

[0278] Reference Figure 19 and Figure 21In some embodiments, the outer peripheral surface of the bushing 132 is a convex spherical surface, and the inner peripheral surface of the receiving cavity 1311 includes a concave spherical surface 13111. The concave spherical surface 13111 and the convex spherical surface have the same shape and fit together. In this way, when the end of the output shaft 532 away from the motor body 50 is slightly deflected or deformed, the bushing 132 will slightly deflect relative to the damping pad 131 along with the output shaft 532, avoiding rigid constraint on the output shaft 532. This can further reduce the probability of damage to the bearings in the second motor 5, thereby extending the service life of the second motor 5.

[0279] Reference Figure 19 and Figure 21 In some embodiments, the inner peripheral surface of the receiving cavity 1311 further includes a guide surface 13112, which is located between the concave spherical surface 13111 and the opening of the receiving cavity 1311. The guide surface 13112 is formed as an annular surface, and the radial dimension of the annular surface gradually increases along the direction from the shock-absorbing pad 131 to the motor body 50.

[0280] During the process of installing the bushing 132 into the receiving cavity 1311 of the damping pad 131, the guide surface 13112 can play a guiding role, so that the bushing 132 can be installed into the receiving cavity 1311 more smoothly, which helps to improve assembly efficiency.

[0281] Reference Figure 19 and Figure 21 In some embodiments, the damping pad 131 has a first through hole 1312 on the side away from the motor body 50, and the first through hole 1312 communicates with the receiving cavity 1311. By providing the first through hole 1312 on the side of the damping pad 131 away from the motor body 50, the first through hole 1312 can vent air during the process of installing the bushing 132 into the damping pad 131, thereby allowing the bushing 132 to be installed more smoothly into the receiving cavity 1311 of the damping pad 131.

[0282] In this application, the mounting wall 12 defines a mounting groove 121 with an opening facing the second motor 5. The shock-absorbing pad 131 is installed in the mounting groove 121. The mounting groove 121 includes a bottom wall 1211 and a peripheral wall 1212. The bottom wall 1211 is disposed opposite to the second motor 5. The peripheral wall 1212 is connected to the side of the bottom wall 1211 facing the second motor 5 and surrounds the bottom wall 1211.

[0283] The bottom wall 1211 of the mounting groove 121 is provided with a second through hole 12111. By providing the second through hole 12111 in the bottom wall 1211 of the mounting groove 121, the second through hole 12111 can vent air during the installation of the shock-absorbing pad 131 into the mounting groove 121, so that the shock-absorbing pad 131 can be installed into the mounting groove 121 more smoothly.

[0284] In this application, the first through hole 1312 and the second through hole 12111 are arranged opposite to each other, and the first through hole 1312 connects the second through hole 12111 and the receiving cavity 1311. In the embodiment where the shock-absorbing pad 131 and the bushing 132 are assembled first and then installed into the mounting groove 121, by setting the first through hole 1312 on the side of the shock-absorbing pad 131 away from the motor body 50, and setting the second through hole 12111 on the bottom wall 1211 of the mounting groove 121, the first through hole 1312 and the second through hole 12111 can vent air during the process of inserting the output shaft 532 into the bushing 132, thereby making the output shaft 532 insert into the bushing 132 more smoothly.

[0285] The diameters of the first through-hole 1312 and the second through-hole 12111 are both greater than 1 mm, for example, the diameters of the first through-hole 1312 and the second through-hole 12111 are 1.5 mm, 2 mm, 2.5 mm, etc. This arrangement is more conducive to venting.

[0286] The diameter of the first through hole 1312 is smaller than the maximum diameter of the bushing 132. This prevents the bushing 132 from coming out of the first through hole 1312 and also ensures the structural strength of the damping pad 131. The diameter of the second through hole 12111 is less than or equal to the diameter of the first through hole 1312. This ensures the structural strength of the mounting wall 12, improves the installation reliability of the elastic support 13, and thus improves the reliability of the second motor 5.

[0287] Reference Figure 12 In some embodiments, the damping pad 131 also has a plurality of damping cavities 1313 surrounding the receiving cavity 1311.

[0288] Therefore, by setting multiple damping cavities 1313, the position of the output shaft 532 relative to the mounting groove 121 can be adjusted, reducing the problem of misalignment between the central axis of the output shaft 532 and the central axis of the mounting groove 121 caused by assembly errors, as well as the problem of misalignment between the central axis of the output shaft 532 and the central axis of the mounting groove 121 caused by vibration during the operation of the second motor 5.

[0289] To improve the installation stability and reliability of the shock-absorbing pad 131 within the mounting groove 121, refer to Figure 12 The outer peripheral wall of the shock-absorbing pad 131 is provided with a plurality of protruding ribs 1314. The plurality of protruding ribs 1314 are arranged at intervals in the circumference of the shock-absorbing pad 131. Each protruding rib 1314 extends along the axial direction of the shock-absorbing pad 131. The protruding ribs 1314 can abut against the peripheral wall 1212 of the mounting groove 121, making the shock-absorbing pad 131 more firmly installed.

[0290] In this application, the end of the output shaft 532 away from the motor body 50 can be rounded, or the end of the output shaft 532 away from the motor body 50 can be spherical. On the one hand, it is more convenient to insert the output shaft 532 into the bushing 132, and on the other hand, it can reduce the damage to the bushing 132 and other structures caused by the end of the output shaft 532 away from the motor body 50.

[0291] Reference Figure 17 In some embodiments, the end of the groove peripheral wall 1212 away from the groove bottom wall 1211 is provided with a snap-fit ​​part 12121. The snap-fit ​​part 12121 stops the shock absorber 131 on the side close to the motor body 50, so as to restrict the shock absorber 131 in the mounting groove 121, prevent the shock absorber 131 from falling out of the mounting groove 121, and ensure the installation reliability and stability of the shock absorber 131.

[0292] In this application, there can be multiple snap-fit ​​parts 12121, which are arranged circumferentially at intervals around the opening of the mounting groove 121. The snap-fit ​​parts 12121 can be processed through the process holes 123 on the bottom wall 1211 of the groove, thus eliminating the need to add a slanted ejector mechanism in the mold, which helps to reduce the manufacturing cost of the mold.

[0293] Reference Figure 19 and Figure 21 In some embodiments, the outer diameter of the elastic support 13 is D1, where D1 ≤ 60 mm and D1 ≥ 12 mm. For example, the outer diameter D1 of the elastic support 13 can be 12 mm, 20 mm, 30 mm, 40 mm, 50 mm, or 60 mm.

[0294] If the outer diameter D1 of the elastic support 13 is too small, the elastic support 13 cannot better absorb the vibration and impact energy generated by the output shaft 532 during rotation through its own deformation. If the outer diameter D1 of the elastic support 13 is too large, it will result in the elastic support 13 occupying too much area, thereby affecting the structural strength of the mounting wall 12, or the area occupied by other structures on the mounting wall 12.

[0295] In the above technical solution, by limiting the outer diameter D1 of the elastic support member 13 to meet the above range, the elastic support member 13 can better provide elastic support for the end of the output shaft 532 away from the motor body 50, while ensuring the structural strength of the mounting wall 12 and the area occupied by the other structures on the mounting wall 12. This reduces bearing damage in the second motor 5, extends the service life of the second motor 5, and also reduces operating noise.

[0296] Reference Figure 18 and Figure 19In some embodiments, the motor body 50 is disposed within the exhaust volute 9. The fresh air volute 8 defines a communicating fan cavity V011 and an air inlet cavity V012. The fresh air fan 6 is disposed within the fan cavity V011. A mounting wall 12 is formed on the fresh air volute 8 and located between the fan cavity V011 and the air inlet cavity V012. An air passage 122 connects the fan cavity V011 and the air inlet cavity V012. The rotation of the fresh air fan 6 allows outdoor air to enter the air inlet cavity V012 from the fresh air inlet 801, pass through the air passage 122 into the fan cavity V011, and finally enter the room from the fresh air outlet 802.

[0297] Reference Figure 20 and Figure 21 In some embodiments, the motor body 50 is disposed inside the fresh air volute 8. The exhaust volute 9 includes an exhaust end plate 91 and an exhaust enclosure plate 92. The exhaust end plate 91 is disposed opposite to the fresh air volute 8, and the exhaust enclosure plate 92 is connected between the exhaust end plate 91 and the fresh air volute 8.

[0298] The exhaust end plate 91 is formed as a mounting wall 12, and the exhaust air inlet 901 is located on the mounting wall 12 and forms an air passage 122. The rotation of the exhaust fan 7 allows indoor air to enter the exhaust volute 9 from the exhaust air inlet 901 and then enter the outside from the exhaust air outlet 902.
