For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0084] The solution of the present application introduces the structure of a wall-mounted air conditioner 10000.

[0085] Before that, the structure of a common air conditioner is introduced first. A common air conditioner is a split-type air conditioner, including an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected through pipelines to transfer refrigerant. The indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 41.

[0086] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling element. The compressor, the outdoor heat exchanger, the throttling element, and the indoor heat exchanger 2 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger 2 respectively to achieve the cooling mode or the heating mode of the air conditioner.

[0087] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0088] The outdoor heat exchanger is configured to exchange heat between the outdoor air and the refrigerant flowing in the outdoor heat exchanger. For example, the outdoor heat exchanger operates as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor dissipates heat to the outdoor air through the outdoor heat exchanger and condenses. The outdoor heat exchanger operates as an evaporator in the heating mode of the air conditioner, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

[0089] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant flowing in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0090] The outdoor fan is configured to suck external air into the outdoor unit and send the outdoor air that has exchanged heat with the outdoor heat exchanger to the outside, and the outdoor fan provides power for the flow of the outdoor air.

[0091] The throttle member is connected between the outdoor heat exchanger and the indoor heat exchanger 2. The throttle member is used to adjust the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2 to regulate the refrigerant flow rate between the outdoor heat exchanger and the indoor heat exchanger 2. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger 2 will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger 2. The throttle member can be a throttle tube, an electronic valve, etc. When the throttle member is an electronic valve, the opening degree of the throttle member is adjustable to regulate the flow rate and pressure of the refrigerant flowing through the throttle member.

[0092] Some solutions of the air conditioner further include a four-way valve. The four-way valve is connected in the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can execute a refrigeration mode or a heating mode.

[0093] The indoor heat exchanger 2 is configured to exchange heat between the indoor air and the refrigerant flowing in the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 further includes heat exchange fins to increase the contact area between the indoor air and the refrigerant flowing in the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0094] The heat exchange fan 41 is configured to suck the indoor air into the indoor unit and send the indoor air that has exchanged heat with the indoor heat exchanger 2 into the room, and the heat exchange fan 41 provides power for the flow of the indoor air.

[0095] The air conditioner further includes a control device, which is mainly used to control the operating frequency of the compressor and the opening degree of the throttle member. Some control devices can also control the rotational speed of the outdoor fan and the rotational speed of the heat exchange fan 41, etc. The control device is connected to the compressor, the throttle member, the outdoor fan and the heat exchange fan 41 through data lines to transmit communication information.

[0096] 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 the 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.

[0097] The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a thumb drive).

[0098] A wall-mounted air conditioner 10000 proposed in this application is an indoor unit. The wall-mounted air conditioner 10000 is usually installed on a wall, for example, it can be installed in the upper area of an indoor wall.

[0099] The wall-mounted air conditioner 10000 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0100] The wall-mounted air conditioner 10000 according to an embodiment of the present application, as Figure 1 and Figure 2 shown, includes: a main body 1000.

[0101] The main body 1000 includes: a housing 1. An accommodation cavity V1 is formed inside the housing 1, and a heat exchange air inlet 101 and a heat exchange air outlet 102 are formed on the housing 1. The housing 1 can play a protective role and constitute the overall external structure of the wall-mounted air conditioner 10000.

[0102] Generally, the housing 1 is an elongated shell as a whole, and the length direction of the housing 1 is arranged along the horizontal direction, that is, the housing 1 is installed on the wall transversely. In actual products, in order to drain condensate, in some embodiments, the housing 1 is installed on the wall transversely and forms a small angle with the horizontal plane.

[0103] Referring to Figure 3 and Figure 4, the main body 1000 further includes: an indoor heat exchanger 2, which is disposed in the accommodation cavity V1. As described above, the indoor heat exchanger 2 is a part of the refrigerant circuit, with refrigerant flowing inside, and is used to cool or heat the air flowing across the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is usually arranged to extend along the length direction of the casing 1. For example, the indoor heat exchanger 2 is a two-fold or three-fold heat exchanger, and each fold of the indoor heat exchanger 2 is a plate-like structure extending along the length direction.

[0104] Referring to Figure 3 and Figure 4 , the main body 1000 further includes: a base 3, which is disposed in the accommodation cavity V1. The base 3 is an installation and support structure inside the main body 1000, and the indoor heat exchanger 2 can be installed on the base 3. Specifically, a volute tongue air duct V03 is formed on the base 3. After the indoor air enters the casing 1, the flow direction is guided through the volute tongue air duct V03, ensuring that the resistance suffered by the indoor air when flowing through the indoor heat exchanger 2 is relatively small.

[0105] Referring to Figure 4 , the main body 1000 further includes: a heat exchange fan 41, which is arranged in the volute tongue air duct V03. In the solution of the present application, the heat exchange fan 41 can be selected as a cross-flow fan, which has low noise and a large air volume, and the air outlet wind speed of the cross-flow fan is relatively evenly distributed along the axial direction of the cross-flow fan, which is beneficial to increasing the air supply distance and air supply range. Moreover, by using a cross-flow fan and arranging the cross-flow fan along the length direction of the main body 1000, it is beneficial to drive the air flow to flow through the entire indoor heat exchanger 2, ensuring the balance of the heat exchange efficiency at each position of the indoor heat exchanger 2.

[0106] Referring to Figure 4 , the main body 1000 further includes: a first motor 42, which is disposed in the accommodation cavity V1. The first motor 42 is used to drive the heat exchange fan 41 to rotate, so that heat exchange between the air inside the air conditioner and the indoor space can be carried out.

[0107] By providing a heat exchange air outlet 102 and a heat exchange air inlet 101 on the casing 1, when the heat exchange fan 41 operates, the indoor air is sucked into the casing 1 from the heat exchange air inlet 101, and after heat exchange with the indoor heat exchanger 2, the heat-exchanged air is sent to the indoor through the heat exchange air outlet 102.

[0108] Thus, the adjustment of the indoor environmental temperature is realized. The indoor heat exchanger 2 can be used as an evaporator to provide a cooling air flow towards the indoor space through the heat exchange air outlet 102, or the indoor heat exchanger 2 can be used as a condenser to provide a heating air flow towards the indoor space through the heat exchange air outlet 102.

[0109] In the solution of this application, in the height direction of the main body 1000, the heat exchange air inlet 101 is located above the heat exchange air outlet 102, which facilitates air intake from above and air outlet from below. In this application, the height direction of the main body 1000 is the up-and-down direction.

[0110] It can be understood that the main body 1000 is usually installed on the wall. To avoid interfering with people's daily lives, the position where the main body 1000 is hung is usually relatively high. By setting the main body 1000 to blow out heat exchange air from below, the blown heat exchange air is not easily blocked by the roof or the ground. In this way, the resistance consumed during the blowing process of the heat exchange air is small, and the air supply range is wide, so that the heat exchange air can flow to the entire indoor space as soon as possible, improving the heat exchange efficiency.

[0111] Refer to 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 intake air from above, which can avoid intake air from the heat exchange air outlet 102 and prevent the heat exchange air from being directly sucked into the heat exchange air inlet 101 after being blown out from the heat exchange air outlet 102, reducing the process of the heat exchange air idling without participating in indoor heat exchange.

[0112] In some specific embodiments, the heat exchange air inlet 101 is located at the top of the casing 1, that is, in an area that is not visible to the user, hiding the heat exchange air inlet 101 can improve the aesthetic appearance.

[0113] In some embodiments, the heat exchange air outlet 102 is located directly in front of the casing 1, that is, the heat exchange air outlet 102 blows air towards the front side of the main body 1000. It can be understood that the side where the main body 1000 is connected to the wall is usually referred to as the back or the rear side, and the side opposite to the rear side is referred to as the front side. Therefore, when the heat exchange air outlet 102 is located directly in front of the casing 1, the air outlet is away from the wall, and the blowing resistance is small, and the air supply range is wide.

[0114] In some other embodiments, the heat exchange air outlet 102 is located at the front side of the casing 1 and close to the bottom, or it can be said that the heat exchange air outlet 102 is located at the front lower corner of the casing 1. At this time, the heat exchange air blown out by the heat exchange air outlet 102 will flow downward while flowing forward. In this way, after the heat exchange air is sent to a certain distance, the heat exchange air can sink and fall on people or objects on the ground, enabling people or objects on the ground to be in a comfortable indoor environment as soon as possible.

[0115] In the solution of 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 driving component that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotation, and is also a power driving component for air supply.

[0116] The heat exchange fan 41 is placed on the side of the indoor heat exchanger 2 away from the heat exchange air inlet 101, which can evenly distribute the aerodynamic force generated when the heat exchange fan 41 rotates. A part of it is distributed to the air inlet side, so that the inhaled air can overcome the air resistance generated by the indoor heat exchanger 2 when flowing into the volute tongue air duct V03, and the other part is distributed to the air supply side, so that when the heat-exchanged air is blown out from the heat exchange air outlet 102, the conveying distance is farther.

[0117] In the solution of this application, as Figure 4 shown, the first motor 42 is located at one end of the main body 1000 in the length direction. This facilitates the installation and maintenance of the first motor 42, and the overall main body 1000 does not need to become too high or too thick due to the setting of the first motor 42. Here, the height direction of the main body 1000 is consistent with the up and down direction, and the thickness direction of the main body 1000 is consistent with the front and back direction.

[0118] In the solution of this application, the wall-mounted air conditioner 10000 further includes a second motor 5 (as Figure 8 shown), the second motor 5 is arranged in the accommodating cavity V1, and the second motor 5 is located at the other end of the main body 1000 in the length direction.

[0119] In this way, the first motor 42 and the second motor 5 are located at both ends of the main body 1000 in the length direction. On the one hand, the two motors are separated and the distance is far, so the electromagnetic interference between them is small. On the other hand, the two motors are arranged at both ends of the main body 1000 in the length direction, rather than in the thickness or height direction of the main body 1000, making the main body 1000 of the wall-mounted air conditioner 10000 slender in shape, with a slender, light and thin appearance.

[0120] Referring to Figure 9 and Figure 10 , the second motor 5 includes: a stator part 51 and a rotor part 52, and the stator part 51 and the rotor part 52 are the main parts of the second motor 5. The stator part 51 has a wound coil, and the coil generates an alternating magnetic field after passing through alternating current, and the rotor part 52 generates induction and rotates in the alternating magnetic field.

[0121] Optionally, the rotor part 52 can be a magnetic ring or a magnetic tile, and the rotor part 52 is preferably a magnetic ring, so that the magnetic leakage loss can be reduced, the magnetic flux can be enhanced, and the power output efficiency of the second motor 5 can be improved. Moreover, when a magnetic ring is used, the magnetic field distribution is uniform, the anti-interference ability is good, and the mechanical precision is higher.

[0122] The second motor 5 is an outer rotor motor. In the radial direction of the stator portion 51, the rotor portion 52 is arranged around the outside of the stator portion 51. The second motor 5 selects an outer rotor motor. Not only is the structure of the outer rotor motor simple, but also since the rotor portion 52 is arranged around the outside of the stator portion 51 in the radial direction of the stator portion 51, the diameter size of the rotor portion 52 is large, and a larger torque can be obtained, which can be used in scenarios such as low-speed high-torque and direct drive. That is, when the second motor 5 outputs power outward, a speed reducer does not need to be provided to reduce speed and increase torque, saving the space occupied by the speed reducer.

[0123] In addition, the rotor portion 52 is located radially outside the stator portion 51, with a relatively large heat dissipation area and good heat dissipation performance, which is beneficial to the stable operation of the second motor 5. And after being arranged in this way, the diameter size of the second motor 5 can be controlled to be relatively small, without occupying the space of the air flow channel.

[0124] Refer to Figure 9 and Figure 10 Figure, the second motor 5 further includes: a motor housing 53, and the motor housing 53 can support and protect the main body part of the second motor 5.

[0125] The motor housing 53 is fixedly connected to the rotor portion 52 and rotates synchronously with the rotor portion 52. In this way, the rotor portion 52 can be fixed by the motor housing 53, which is convenient for connecting with external structures.

[0126] The second motor 5 further includes: an output shaft 532. The output shaft 532 is fixedly connected to the motor housing 53, and one end of the output shaft 532 extends along the axial direction of the motor housing 53 toward the side of the heat exchange fan 41, and the other end of the output shaft 532 extends into the stator portion 51. That is to say, the main body part of the second motor 5 is separated from the indoor heat exchanger 2 and the heat exchange fan 41 by a certain distance, reducing the vibration transmitted from the operation of the second motor 5 to the indoor heat exchanger 2 and the heat exchange fan 41.

[0127] Refer to Figure 8 Figure, the wall-mounted air conditioner 10000 further includes: a fresh air fan 6. The fresh air fan 6 is a centrifugal fan with axial air inlet and radial air outlet. The fresh air fan 6 is located on the side of the heat exchange fan 41 away from the first motor 42. The fresh air fan 6 is located between the heat exchange fan 41 and the motor housing 53, and the fresh air fan 6 is connected to the output shaft 532 of the second motor 5.

[0128] Refer to Figure 8 Figure, the wall-mounted air conditioner 10000 further includes: an exhaust fan 7. The exhaust fan 7 is a centrifugal fan with axial air inlet and radial air outlet. In the length direction of the main body 1000, the exhaust fan 7 is located on the side of the fresh air fan 6 facing the second motor 5. The exhaust fan 7 is sleeved on the radial outside of the motor housing 53, and the exhaust fan 7 is fixedly connected to the motor housing 53. Among them, the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate synchronously in the working state.

[0129] The characteristics of the centrifugal fan itself include a compact structure, a large air volume, and low noise. Moreover, when the rotational speed decreases, the fan noise decreases significantly. Therefore, for the fresh air fan 6 and the exhaust fan 7, centrifugal fans with relatively small sizes can be selected to meet the large air volume requirements. The vibration noise of the centrifugal fan is small and it is not easy to resonate with the indoor heat exchanger 2, effectively controlling the overall vibration and noise of the wall-mounted air conditioner 10000.

[0130] Both the fresh air fan 6 and the exhaust fan 7 adopt centrifugal fans, and the air directions of the fresh air fan 6 and the exhaust fan 7 can be reasonably arranged. Specifically, the fresh air fan 6 takes in air axially and discharges air radially, and the exhaust fan 7 takes in air axially and discharges air radially. The fresh air fan 6 and the exhaust fan 7 take in air from two ends far away from each other, and then after being driven, the fresh air and the exhaust air are both discharged radially. The flow paths of the fresh air and the exhaust air do not need to overlap axially and do not need to cross. This helps to reduce the avoidance corner design of the fresh air and exhaust air paths, reduce wind resistance and energy consumption, ensure the air volume, and reduce noise.

[0131] Refer to Figures 5 - 8 , the wall-mounted air conditioner 10000 further includes: a fresh air volute 8. A fresh air duct V01 is formed inside the fresh air volute 8. The fresh air fan 6 is installed inside the fresh air volute 8. A fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air volute 8. When the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802.

[0132] Refer to Figures 5 - 8 , the wall-mounted air conditioner 10000 further includes: an exhaust volute 9. The exhaust volute 9 is located on the side of the fresh air volute 8 facing the second motor 5. An exhaust duct V02 is formed inside the exhaust volute 9. The exhaust fan 7 is installed inside the exhaust volute 9. An exhaust air inlet 901 and an exhaust air outlet 902 are formed on the exhaust volute 9. When the exhaust fan 7 rotates, indoor air can enter the exhaust volute 9 from the exhaust air inlet 901, and the indoor air entering the exhaust volute 9 can be discharged to the outside from the exhaust air outlet 902.

[0133] In the solution of this application, the fresh air volute 8 and the fresh air fan 6 form a fresh air module. The fresh air fan 6 is arranged in the fresh air duct V01 and is used to drive the air flow to be inhaled from the fresh air inlet 801 and discharged to the room through the fresh air outlet 802. The operation of the fresh air fan 6 provides the power for the fresh air to flow. Thus, by setting the cooperation of the fresh air duct V01 and the fresh air fan 6, when the air in the room is relatively dirty or the air quality is average, the fresh air fan 6 can drive the relatively fresh outdoor air into the indoor environment to improve the indoor air flow environment.

[0134] In the solution of this application, an exhaust volute 9 and an exhaust fan 7 form an exhaust module. The exhaust fan 7 is arranged in an exhaust air duct V02 and is used to drive air flow to be inhaled from an exhaust air inlet 901 and discharged from an exhaust air outlet 902 to the outside of the room. The operation of the exhaust fan 7 provides the power for the flow of the dirty air flow.

[0135] Thus, by setting the exhaust air duct V02 to cooperate with the exhaust fan 7, when the air in the room is relatively dirty or the air quality is average, the exhaust fan 7 can suck and discharge the dirty air flow in the indoor space. After the indoor air volume is reduced in this way, fresh air will be inhaled from the outside or from other rooms through doors and windows, etc., so as to reduce the dirtiness degree of the indoor air.

[0136] A second motor 5, a fresh air fan 6, an exhaust fan 7, a fresh air volute 8 and an exhaust volute 9 form a two-way ventilation component, and the two-way ventilation component is arranged in a main body 1000. The two-way ventilation component can provide fresh air for the room and can discharge the indoor air to the outside.

[0137] It should be noted that the operation mode of the two-way ventilation component in the wall-mounted air conditioner 10000 can be set according to actual usage requirements. In some embodiments, the two-way ventilation component can simultaneously operate in a fresh air mode and an exhaust mode, that is, the fresh air duct V01 and the exhaust air duct V02 can be opened at the same time. While the dirty air flow in the room flows to the outdoor space, the fresh air flow outside can also enter the indoor space. Through the combined air flow drive of one in and one out, it is beneficial to increase the improvement efficiency of the air flow in the indoor space, so as to meet the user's needs in time when the user urgently needs to discharge or update the indoor air.

[0138] Moreover, since while discharging the indoor air to the outside, fresh air outside is supplemented into the room to keep the indoor air volume sufficient, it is easier to suck away the indoor air. For example, when there are irritating gases (such as gases released by home decoration materials), gas leakage of gas or other gases in the room, the two-way ventilation component can be set to simultaneously operate in the fresh air mode and the exhaust mode to achieve rapid ventilation. And compared with the design of simply introducing fresh air in the conventional fresh air structure, the two-way ventilation component of this application has a larger purification flow rate per unit time, a higher ventilation efficiency, and a faster purification effect.

[0139] Moreover, during ventilation, it is avoided that the indoor temperature changes violently like directly opening a window, which can avoid causing discomfort to the indoor personnel due to sudden rise or fall of the temperature. And the position of the main body 1000 is relatively high, and the ventilation position will not cause discomfort due to being too close to people.

[0140] In some other embodiments, the two-way ventilation component can operate in the fresh air mode and the exhaust air mode alternatively, that is, when the two-way ventilation component turns on the fresh air mode, the exhaust air mode is shut down. At this time, only the fresh air duct V01 is ventilated, and the exhaust air duct V02 is not ventilated. Or when the two-way ventilation component turns on the exhaust air mode, the fresh air mode is shut down. At this time, the fresh air duct V01 is not ventilated, and the exhaust air duct V02 is ventilated.

[0141] In some embodiments, a two-way ventilation component is provided in the wall-mounted air conditioner 10000, such as Figure 8 shown, the two-way ventilation component includes: a second motor 5, a fresh air fan 6, an exhaust air fan 7, a fresh air volute 8 and an exhaust air volute 9.

[0142] In this embodiment, the second motor 5 is an external rotor motor. The second motor 5 includes: a stator part 51, a rotor part 52, a motor housing 53 and an output shaft 532. The stator part 51 has a wound coil. In the radial direction of the stator part 51, the rotor part 52 is arranged around the outside of the stator part 51. The motor housing 53 is fixedly connected to the rotor part 52, and the output shaft 532 is fixedly connected to the motor housing 53. One end of the output shaft 532 extends along the axial direction of the motor housing 53 towards the side of the heat exchange fan 41, and the other end of the output shaft 532 extends into the stator part 51 along the axial direction of the motor housing 53.

[0143] In this embodiment, the fresh air fan 6 is a centrifugal fan with axial air inlet and radial air outlet. The fresh air fan 6 is located on the side of the heat exchange fan 41 away from the first motor 42. The fresh air fan 6 is located between the heat exchange fan 41 and the motor housing 53, and the fresh air fan 6 is connected to the output shaft 532 of the second motor 5.

[0144] In this embodiment, the exhaust air fan 7 is a centrifugal fan with axial air inlet and radial air outlet. In the length direction of the main body 1000, the exhaust air fan 7 is located on the side of the fresh air fan 6 facing the second motor 5. The exhaust air fan 7 is sleeved on the radial outside of the motor housing 53, and the exhaust air fan 7 is fixedly connected to the motor housing 53. The second motor 5 drives the fresh air fan 6 and the exhaust air fan 7 to rotate synchronously in the working state.

[0145] In this embodiment, as Figure 8 shown, a fresh air duct V01 is formed in the fresh air volute 8, and the fresh air fan 6 is installed in the fresh air volute 8. As Figure 6 shown, a fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air volute 8. The rotation of the fresh air fan 6 can make the outdoor air enter the fresh air volute 8 from the fresh air inlet 801, and can make the outdoor air entering the fresh air volute 8 enter the room from the fresh air outlet 802.

[0146] In this embodiment, as Figure 8As shown, the exhaust air volute 9 is located on the side of the fresh air volute 8 facing the second motor 5. An exhaust air duct V02 is formed inside the exhaust air volute 9. The exhaust air fan 7 is installed inside the exhaust air volute 9. An exhaust air inlet 901 and an exhaust air outlet 902 are formed on the exhaust air volute 9. When the exhaust air fan 7 rotates, indoor air can enter the exhaust air volute 9 from the exhaust air inlet 901, and the indoor air entering the exhaust air volute 9 can be discharged to the outside from the exhaust air outlet 902.

[0147] In this embodiment, the second motor 5 is located at the end of the main body 1000 in the length direction, and the axial direction of the second motor 5 is arranged along the length direction of the main body 1000. The second motor 5 is the common power source for the fresh air module and the exhaust air module of the two-way ventilation component. To ensure the operation of the fresh air module and the exhaust air module, the second motor 5 needs to have sufficient operating power to drive sufficient air volume flow. Based on the power requirement of the second motor 5, the second motor 5 needs to be of a sufficiently large size.

[0148] In this embodiment, on the premise that the size parameters of the second motor 5 are generally determined, when arranging the fresh air module and the exhaust air module at this time, what is considered is how to utilize the space where the second motor 5 is located and occupy as little additional space as possible. Among them, in this embodiment, both the fresh air fan 6 and the exhaust air fan 7 adopt centrifugal fans and are connected to the same motor. This not only saves the number of motors, but also keeps the two centrifugal fans arranged in a stacked manner along the axial direction of the second motor 5, that is, the two centrifugal fans are arranged in a stacked manner along the length direction of the main body 1000.

[0149] In this embodiment, the centrifugal fan itself is relatively flat in the axial direction. Stacking the fresh air fan 6 and the exhaust air fan 7 in this way can reduce the overall occupied axial dimension and make the length of the main body 1000 not need to be too long. Since the fresh air fan 6 and the exhaust air fan 7 are connected to the same motor and rotate synchronously, they are in step with each other and do not need to have too large a gap between them. The axial distance between the fresh air fan 6 and the exhaust air fan 7 can be arranged relatively close.

[0150] It should be noted that when referring to "axial direction", "radial direction", and "circumferential direction" in describing the internal structure of the two-way ventilation component, they are all based on the axial direction, radial direction, and circumferential direction of the motor. That is, the direction parallel to the extension direction of the output shaft 532 of the second motor 5 is the axial direction, the direction perpendicular to the extension direction of the output shaft 532 is the radial direction, and the direction around the output shaft 532 is the circumferential direction.

[0151] In the above solution, by using an outer-rotor motor for the second motor 5, the exhaust fan 7 is sleeved on the radial outside of the motor housing 53, a part of the second motor 5 in the motor housing 53 is embedded in the exhaust fan 7, and a part of the output shaft 532 is embedded in the fresh air fan 6, so that in the length direction of the main body 1000, the second motor 5 almost overlaps with the exhaust fan 7 and the fresh air fan 6, the parts of the exhaust fan 7 and the fresh air fan 6 located outside the second motor 5 in the axial direction are less, and the overall axial dimension of the two-way ventilation component is close to the axial dimension of the second motor 5, thereby controlling the length dimension of the main body 1000.

[0152] Among them, the main body part of the second motor 5 is located in the exhaust fan 7, rather than in the fresh air fan 6, which can provide more air flow space for the fresh air duct V01 and is beneficial to the intake of fresh air. It can be understood that when the wall-mounted air conditioner 10000 is in the cooling state, the fresh air module sucks fresh air from the outside to the inside, and the cold quantity generated by the wall-mounted air conditioner 10000 can still remain in the room with little cold quantity loss.

[0153] In this embodiment, the indoor air is discharged to the outside through the exhaust module. By setting the exhaust air volume less than the fresh air volume, the cold quantity loss can be reduced. Therefore, the second motor 5 occupying the space of the exhaust duct V02 is reduced, and more fresh air ducts V01 are left, which is beneficial to ensuring a larger fresh air volume.

[0154] Moreover, since the second motor 5 uses an outer-rotor motor that can adapt to scenarios such as low-speed high-torque and direct drive, a speed reducer does not need to be set, and the exhaust fan 7 can be directly sleeved on the radial outside of the motor housing 53. This not only avoids the increase in the overall axial dimension caused by the speed reducer but also avoids the increase in the structural layout difficulty caused by the speed reducer. Only by fixedly connecting the exhaust fan 7 to the motor housing 53 and connecting the fresh air fan 6 to the output shaft 532 of the second motor 5, the exhaust fan 7 and the fresh air fan 6 can be arranged coaxially and stacked, and the two can rotate synchronously and maintain a small gap without a too large interval. In this way, it also ensures that the overall axial dimension of the two-way ventilation component is close to the axial dimension of the second motor 5, and the length dimension of the main body 1000 is controllable.

[0155] In this embodiment, the fresh air fan 6 is arranged on the side of the exhaust fan 7 facing the indoor heat exchanger 2, which can reduce the cold or heat loss in the room and improve the comfort when the fresh air is blown into the room. Specifically, the fresh air module where the fresh air fan 6 is located is close to the indoor heat exchanger 2. The fresh air sucked from the outside can absorb the cold or heat released by the indoor heat exchanger 2 before being blown into the room, so that the fresh air is as close as possible to the indoor temperature before being blown into the room.

[0156] When the wall-mounted air conditioner 10000 is cooling, the fresh air absorbs the cold of the indoor heat exchanger 2, and the temperature of the blown fresh air decreases, avoiding blowing the outdoor hot air directly into the room. When the wall-mounted air conditioner 10000 is heating, the fresh air absorbs the heat of the indoor heat exchanger 2, and the temperature of the blown fresh air increases, avoiding blowing the outdoor cold air directly into the room. The exhaust module where the exhaust fan 7 is located is far from the indoor heat exchanger 2, so the cold or heat absorbed from the indoor air after absorbing air from the room is small, and the loss of cold or heat discharged to the outdoor is small.

[0157] In this embodiment, the fresh air fan 6 is arranged on the side of the exhaust fan 7 facing the indoor heat exchanger 2, and when the indoor heat exchanger 2 is cooling, the entry of condensed water into the air duct can also be reduced. Specifically, for the exhaust volute 9 of the exhaust module, its exhaust air inlet 901 takes in air from the indoor, and the exhaust fan 7 takes in air axially, so the exhaust air inlet 901 is located on the side of the exhaust volute 9 away from the indoor heat exchanger 2. When there is condensed water on one side of the indoor heat exchanger 2, the condensed water is not easily sucked into the exhaust air duct V02 by the exhaust module, reducing the risk of water accumulation and bacteria breeding in the exhaust air duct V02. When the fresh air module takes in air from the outdoor when the fresh air fan 6 rotates, the condensed water on the indoor heat exchanger 2 will not be sucked into the fresh air duct V01 either, reducing the risk of water accumulation and bacteria breeding in the fresh air duct V01.

[0158] In addition, in this embodiment, the exhaust fan 7 is located on the side of the fresh air fan 6 away from the indoor heat exchanger 2. For the exhaust fan 7 that needs to take in air from the room, the intake energy consumption it needs is also relatively low. Specifically, when the wall-mounted air conditioner 10000 is cooling or heating, the heat exchange fan 41 operates to drive the indoor intake air to flow through the indoor heat exchanger 2. The exhaust fan 7 is located at the end of the main body 1000, and the air inlet end of the exhaust fan 7 is far from the air inlet end of the heat exchange fan 41. The exhaust fan 7 does not need to suck air from the air inlet end of the heat exchange fan 41, and the intake energy consumption of the exhaust fan 7 can be reduced. In this way, sufficient exhaust air volume can be ensured, and it can also ensure that there is enough indoor air flowing through the indoor heat exchanger 2 to obtain sufficient heat exchange air, so that the overall energy consumption of the wall-mounted air conditioner 10000 will not be too high.

[0159] In this embodiment, the fresh air module and the exhaust air module are effectively integrated, enabling the two modules to rationally utilize their respective structural and spatial characteristics to complete the flat design. This not only reduces the overall size and weight of the two-way ventilation component, making the two-way ventilation component lightweight and the air ducts non-interfering with each other. The two-way ventilation component is arranged at one end in the length direction of the main body 1000. Compared with the main body without the two-way heat exchange component, only the lateral length is increased, and the height and thickness of the main body 1000 can generally remain unchanged or change slightly, making the appearance of the main body 1000 thin and light. When hung on the wall, it will not affect the indoor space layout due to being too obtrusive, nor will it cause difficulties in fixing the wall-mounted air conditioner 10000 due to being too heavy, reducing the risk of falling off the wall. The overall wall-mounted air conditioner 10000 is still a thin and light model. When hung on the wall, it is not only beautiful but also has controllable weight and safe to use.

[0160] In the solution of the present application, in the height direction of the main body 1000, the fresh air inlet 801 is located below the main body 1000. It can be understood that the fresh air inlet 801 needs to be connected to a pipe to introduce outdoor air. Here, this pipe is called the fresh air introduction pipe 141 (as Figure 2 shown). The fresh air introduction pipe 141 can be a part of the wall-mounted air conditioner 10000, or it can be a fresh air introduction pipe 141 separately configured by the user after purchasing the wall-mounted air conditioner 10000.

[0161] By arranging the fresh air inlet 801 below the main body 1000, the fresh air introduction pipe 141 can be connected to the fresh air inlet 801 from below, and the connection part generally extends in the up-down direction instead of extending in the front-back direction to make the main body 1000 too thick. Thus, the wall-mounted air conditioner 10000 can still maintain a thin and light appearance. Moreover, the part of the fresh air volute 8 where the fresh air fan 6 is installed is circular. Based on the axis of the fresh air volute 8 extending along the length direction of the main body 1000, there is free space on both the front and rear sides of the bottom of this circle. This part of the space can be used to set the fresh air inlet 801 to connect the fresh air introduction pipe 141. Thus, the connection part between the fresh air introduction pipe 141 and the fresh air inlet 801 can be placed in this free space without occupying additional space, so that the height dimension of the main body 1000 can be controlled.

[0162] In the solution of the present application, in the height direction of the main body 1000, the exhaust air outlet 902 is located below the main body 1000. It can be understood that the exhaust air outlet 902 needs to be connected to a pipe to guide the indoor air to the outside. Here, this pipe is called the exhaust air extraction pipe 142 (as Figure 2 shown). The exhaust air extraction pipe 142 can be a part of the wall-mounted air conditioner 10000, or it can be an exhaust air extraction pipe 142 separately configured by the user after purchasing the wall-mounted air conditioner 10000.

[0163] The exhaust air outlet 902 is arranged below the main body 1000, so that the exhaust air lead-out pipe 142 can be connected to the exhaust air outlet 902 from below. The connection part extends generally in the vertical direction, rather than in the front-back direction, which would make the main body 1000 too thick. Thus, the wall-mounted air conditioner 10000 can still maintain a thin and light appearance. Moreover, the part of the exhaust air volute 9 where the exhaust air fan 7 is installed is circular. Based on the fact that the axis of the exhaust air volute 9 extends along the length direction of the main body 1000, there is free space on both the front side and the rear side of the bottom of this circle. And based on the characteristics of the axial air inlet and radial air outlet of the exhaust air fan 7, the volute tongue of the exhaust air volute 9 can be arranged generally in the vertical direction and can be placed in the above-mentioned front-side or rear-side free space.

[0164] An exhaust air outlet 902 is provided here to connect the exhaust air lead-out pipe 142, so that the connection part between the exhaust air lead-out pipe 142 and the exhaust air outlet 902 can be placed in this free space without occupying additional space, thus controlling the height dimension of the main body 1000.

[0165] In some specific embodiments, as Figure 2 shown, the wall-mounted air conditioner 10000 further includes: a fresh air inlet pipe 141 connected to the fresh air inlet 801, an exhaust air lead-out pipe 142 connected to the exhaust air outlet 902. A pipe avoidance opening 104 is provided on the bottom wall of the housing 1. The fresh air inlet pipe 141 and the exhaust air lead-out pipe 142 are passed through the pipe avoidance opening 104 and extend out of the main body 1000 from below. The fresh air inlet pipe 141 and the exhaust air lead-out pipe 142 are two independent pipe components, which helps to separate the fresh air flow path and the exhaust air flow path from each other, without intersection, and reduces the risk of air leakage caused by mutual cross-flow.

[0166] A pipe avoidance opening 104 is provided on the bottom wall of the main body 1000, which is convenient for installing the above pipes and ensures the beautiful appearance of the main body 1000. The fresh air inlet pipe 141 and the exhaust air lead-out pipe 142 are connected from below the main body 1000, without affecting the upper area after the wall-mounted air conditioner 10000 is hung on the indoor wall, that is, the fresh air inlet pipe 141 and the exhaust air lead-out pipe 142 will neither interfere with the rear wall nor with the upper roof, and the installation of the wall-mounted air conditioner 10000 is more convenient and fast.

[0167] Furthermore, the air inlet direction of the fresh air inlet 801 is set upward. Specifically, the air inlet direction of the fresh air inlet 801 is perpendicular to the length direction of the main body 1000. In this way, after the two-way ventilation component is set at the end of the wall-mounted air conditioner 10000, when the fresh air inlet pipe 141 is connected to the fresh air inlet 801, the fresh air inlet pipe 141 will not make the whole wall-mounted air conditioner 10000 overly elongated. Even further, the fresh air inlet 801 is located at the bottom of the main body 1000 and is close to the rear side. In this way, after the fresh air inlet pipe 141 is connected to the fresh air inlet 801, it is convenient for the fresh air inlet pipe 141 to be arranged close to the wall.

[0168] Further, the air outlet direction of the exhaust air outlet 902 is set downward. Specifically, the air outlet direction of the exhaust air outlet 902 is perpendicular to the length direction of the main body 1000. In this way, after the two-way ventilation component is arranged at the end of the wall-mounted air conditioner 10000, when the exhaust air outlet pipe 142 is connected to the exhaust air outlet 902, the exhaust air outlet pipe 142 will not overly elongate the overall wall-mounted air conditioner 10000. Further, the exhaust air outlet 902 is located at the bottom of the main body 1000 and is close to the rear side. In this way, after the exhaust air outlet pipe 142 is connected to the exhaust air outlet 902, it is convenient for the exhaust air outlet pipe 142 to be arranged against the wall.

[0169] Of course, the solution of the present application is not limited to this. For example, Figure 1 As shown, the pipe avoidance port 104 can also be arranged on the side wall of the casing 1. After the fresh air inlet pipe 141 is connected to the fresh air inlet 801 from below the main body 1000, it bends and extends horizontally, then extends out from the pipe avoidance port 104 on the side wall of the casing 1, and then extends to the outside. After the exhaust air outlet pipe 142 is connected to the exhaust air outlet 902 from below the main body 1000, it bends and extends horizontally, then extends out from the pipe avoidance port 104 on the side wall of the casing 1, and then extends to the outside.

[0170] It can be understood that a refrigerant pipe and a drain pipe are usually arranged at one end of the main body 1000 in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 with the compressor and the outdoor heat exchanger outside, and the drain pipe is used to discharge the condensed water generated in the wall-mounted air conditioner 10000.

[0171] The pipe avoidance port 104 is arranged on the side wall of the casing 1, and then the fresh air inlet pipe 141 and the exhaust air outlet pipe 142 are arranged horizontally and then led out, which is convenient for at least one of the fresh air inlet pipe 141 and the exhaust air outlet pipe 142 to be juxtaposed with the drain pipe and the refrigerant pipe. Then, the juxtaposed multiple pipes are covered by an outer bundle pipe or a band, so that the multiple pipes are in the shape of one pipe in appearance, so that the number of connecting pipes on the wall-mounted air conditioner 10000 after installation is small and the appearance is simple, which is not only convenient for assembly, but also avoids the risk of multiple pipes bumping.

[0172] In some embodiments, such as Figure 8 and Figure 11 As shown, a receiving groove V07 is formed at the center of the exhaust fan 7 in the radial direction, and at least a part of the stator portion 51 of the second motor 5, at least a part of the rotor portion 52, and at least a part of the motor housing 53 are received in the receiving groove V07.

[0173] Specifically, the hub of the exhaust fan 7 forms an accommodation groove V07. At this time, the main body of the second motor 5 (i.e., the stator part 51 and the rotor part 52) and the motor housing 53 can be placed at the center of the exhaust fan 7, without obstructing the flow of the exhaust air, and can make full use of the hub space of the exhaust fan 7 to reduce the occupied space of the second motor 5 outside.

[0174] Moreover, after the hub of the exhaust fan 7 is sleeved outside the second motor 5, it has a protective effect, and can also make the center of mass of the exhaust fan 7 as close as possible to the center of the rotor part 52. As a result, the bending moment generated by the exhaust fan 7 on the second motor 7 is small, the exhaust fan 7 shakes little when rotating, the exhaust fan 7 operates stably and has low energy consumption.

[0175] In some embodiments, as Figure 1 shown, an air outlet 105 of the housing 1 is provided. The air outlet 105 of the housing corresponds to the fresh air outlet 802 of the fresh air volute 8, so that the fresh air discharged from the fresh air outlet 802 is discharged from the air outlet 105 of the housing.

[0176] In some specific embodiments, the fresh air outlet 802 is located directly in front of the main body 1000, and the air outlet 105 of the housing can correspondingly be provided on the front side of the housing 1, so that it is convenient to output the fresh air directly in front of the main body 1000. When the wall-mounted air conditioner 10000 is installed on the wall, especially at a high position on the wall, there are fewer obstacles directly in front, and blowing air from directly in front can ensure a large air supply area for the fresh air.

[0177] In some other specific embodiments, the fresh air outlet 802 is located at the top of the main body 1000, and the air outlet 105 of the housing can correspondingly be provided on the top wall of the housing 1, so that the fresh air is sent towards the roof, and the roof can be used to guide the flow direction of the fresh air, so that the fresh air flows along the roof to expand the air supply area.

[0178] Moreover, since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, the position of the heat exchange air inlet 101 on the housing 1 is relatively high. In this way, part of the fresh air blown out from the top by the fresh air outlet 802 can be inhaled again through the heat exchange air inlet 101 into the accommodation cavity V1 and flow through the indoor heat exchanger 2.

[0179] Such a setting is beneficial to quickly reaching the room temperature of the fresh air and improving the comfort when the fresh air is blown in on the one hand, and is beneficial to the full mixing of the fresh air and the indoor air flowing through the indoor heat exchanger 2 on the other hand. In this way, the air blown into the room from the heat exchange air outlet 102 is overall fresh, and the uniformity of the fresh air distribution in the room is improved.

[0180] In still some other specific embodiments, the fresh air outlet 802 is located below the main body 1000 to guide the fresh air to flow forward and downward into the room. The air outlet 105 of the housing can correspondingly be provided below the housing 1.

[0181] Since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the position of the heat exchange air outlet 102 on the housing 1 is relatively lower, the fresh air outlet 802 blows fresh air from below, making the air outlet area of the housing air outlet 105 close to or even partially overlapping with the air outlet area of the heat exchange air outlet 102. This is beneficial to the mixing of fresh air and the indoor air after heat exchange. On the one hand, it improves the uniformity of the mixed fresh air in the indoor air. On the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, making the temperature of the fresh air tend to the indoor temperature and improving the blowing comfort.

[0182] Moreover, the air outlet direction of the fresh air outlet 802 is opposite to the air inlet direction of the heat exchange air inlet 101, so the fresh air will not be sucked into the heat exchange air inlet 101, reducing the proportion of the fresh air intake at the heat exchange air inlet 101, making the total air output of the wall-mounted air conditioner 10000 relatively large, and improving the overall circulation efficiency of the indoor air.

[0183] Moreover, the fresh air outlet 802 is located below the main body 1000, close to the activity space of people, which is convenient for people to observe the fresh air outlet condition. This achieves the visual effect of fresh air outlet, which is beneficial to improving people's experience and perception.

[0184] Specifically, when the fresh air outlet 802 is located below the main body 1000, it is usually located at the front side below the main body 1000, so that the fresh air can flow forward and downward, ensuring that the fresh air can reach the ground and also ensuring that the fresh air can reach a sufficient distance.

[0185] Optionally, as Figure 1 and Figure 3 shown, a grille 16 is provided at the housing air outlet 105 of the housing 1 to adjust the air outlet direction of the fresh air.

[0186] In some embodiments, as Figure 3 shown, an exhaust air inlet 901 is formed on the exhaust air volute 9, and the axial direction of the exhaust air inlet 901 is arranged along the length direction of the main body 1000. That is to say, the exhaust air inlet 901 is directly opposite to the axial air inlet end of the exhaust fan 7, making the air intake resistance of the exhaust fan 7 from the exhaust air inlet 901 small, which is beneficial to ensuring the exhaust air intake. When the exhaust air intake is relatively easy, an exhaust fan 7 with a smaller size can be selected to further reduce the size of the two-way ventilation component.

[0187] In some embodiments, as Figure 1 shown, an air inlet 103 is provided at one end of the housing 1 where the second motor 5 is located, and the air inlet 103 is located at the top of the main body 1000. A first connecting air duct V04 is formed between the air inlet 103 and the exhaust air inlet 901. The rotation of the exhaust fan 7 drives the indoor air to enter the first connecting air duct V04 from the air inlet 103, and the indoor air enters the exhaust air volute 9 through the exhaust air inlet 901.

[0188] That is to say, there is no need to connect a physical pipeline between the air inlet 103 of the casing and the exhaust air inlet 901. Only relying on the wind pressure, the air flow is inhaled from the top. The air inlet 103 of the casing is located at the top of the casing 1, that is, in the area that the user cannot see. Hiding the air inlet 103 of the casing can improve the aesthetic appearance.

[0189] In some other embodiments, an air inlet 103 of the casing is provided at one end of the casing 1 where the second motor 5 is located, and the air inlet 103 of the casing is located on the side of the main body 1000. The exhaust fan 7 rotates to drive the indoor air to enter the interior of the casing 1 through the air inlet 103 of the casing, and makes the indoor air enter the exhaust volute 9 through the exhaust air inlet 901. That is to say, there is no need to connect a physical pipeline between the air inlet 103 of the casing and the exhaust air inlet 901, and the air inlet 103 of the casing is located on the side of the main body 1000 and can face the exhaust air inlet 901.

[0190] In this way, on the one hand, the air inlet path from the air inlet 103 of the casing to the exhaust air inlet 901 becomes shorter, and the air inlet path from the air inlet 103 of the casing to the exhaust air inlet 901 is generally arranged along the axial direction of the exhaust fan 7. When the indoor air flows along this air inlet path to the exhaust fan 7, the air flow does not need to change the flow direction multiple times. In this way, the air inlet resistance of the exhaust can be further reduced to ensure the exhaust air intake.

[0191] In some embodiments, the exhaust fan 7 can be a plastic part, so that it is light in weight and low in cost. Of course, the solution of the present application is not limited to this, and the exhaust fan 7 can also be a resin part, a metal part, etc.

[0192] In some embodiments, the fresh air fan 6 can be a plastic part, so that it is light in weight and low in cost. Of course, the solution of the present application is not limited to this, and the fresh air fan 6 can also be a resin part, a metal part, etc.

[0193] Similarly, the exhaust volute 9 can be a plastic part, so that it is light in weight and low in cost. Optionally, the exhaust volute 9 can be an injection molded part. Of course, the solution of the present application is not limited to this, and the exhaust volute 9 can also be a metal part, etc.

[0194] The fresh air volute 8 can be a plastic part, so that it is light in weight and low in cost. Optionally, the fresh air volute 8 can be an injection molded part. Of course, the solution of the present application is not limited to this, and the fresh air volute 8 can also be a metal part, etc.

[0195] In some embodiments, as Figure 11 and Figure 14 shown, the exhaust fan 7 includes an exhaust wheel disc 71 and exhaust blades 72. The exhaust blades 72 are located at the outer edge of the exhaust wheel disc 71 and extend along the axial direction of the exhaust wheel disc 71 in a direction away from the fresh air fan 6.

[0196] Among them, the exhaust fan 7 further includes a convex portion 74 provided on the exhaust wheel disc 71. The center of the convex portion 74 is located on the axis of the exhaust fan 7, and the convex portion 74 extends in the direction of the fresh air fan 6 relative to the exhaust wheel disc 71, so that a receiving groove V07 for the second motor 5 is formed on the side of the convex portion 74 close to the second motor 5. At least a part of the stator portion 51 and at least a part of the rotor portion 52 are received in the receiving groove V07.

[0197] Referring to Figure 5 and Figure 15 , the fresh air volute 8 includes: a first volute 81 and a second volute 82. The first volute 81 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. The second volute 82 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.

[0198] Referring to Figure 14 , the first volute 81 includes a first volute end plate 811 and a first volute shroud 812. The first volute shroud 812 is formed by extending along the edge of the first volute end plate 811 in the direction of the heat exchange fan 41.

[0199] Among them, a central partial area of the first volute end plate 811 forms a recessed portion 813 facing into the fresh air fan 6, and a perforated portion 814 is provided at the center of the recessed portion 813. At least a part of the convex portion 74 is located in the recessed portion 813, and the output shaft 532 is connected to the fresh air fan 6 through the perforated portion 814.

[0200] In this application, the fresh air volute 8 is axially divided into at least the first volute 81 and the second volute 82 for separate processing, which can reduce the manufacturing and assembly difficulties. Moreover, for such a complex housing, separate manufacturing facilitates quality control. The detachable connection between the first volute 81 and the exhaust volute 9 and the detachable connection between the second volute 82 and the first volute 81 are convenient for assembly and subsequent adjustment and maintenance.

[0201] By providing the convex portion 74 at the center of the exhaust wheel disc 71 and forming the recessed portion 813 at the center of the first volute end plate 811, on the one hand, the hub of the exhaust fan 7 is used to form the convex portion 74 to accommodate the second motor 5, and the convex portion 74 can improve the structural strength of the exhaust fan 7. On the other hand, the main body portion of the second motor 5 is assembled in the convex portion 74, occupying more of the exhaust air duct V02 and less of the fresh air duct V01, which is matched with the design that the fresh air volume is greater than the exhaust air volume. Only the output shaft 532 passes through the first volute end plate 811, which helps with sealing, reduces the probability of mutual flow between the fresh air and the exhaust air, and reduces air flow disturbance.

[0202] In the solution of this application, in order to make the wall-mounted air conditioner 10000 more secure and reliable, the external dimensions of the main body 1000 are strictly controlled. In this way, not only are the internal part clearances small and not easily loosened, but also each air duct can be designed shorter, the size of the casing 1 is reduced, thereby reducing the overall weight of the main body 1000, making it safer to hang on the wall and thinner and lighter visually.

[0203] In some embodiments, referring to Figure 8 , the exhaust air volute 9 is connected to the fresh air volute 8, and the first volute end plate 811 is shared between the two. The fresh air duct V01 and the exhaust air duct V02 are separated by the first volute end plate 811. This setting enables there to be no need for an interval gap between the exhaust air volute 9 and the fresh air volute 8, further reducing the axial dimension of the two-way ventilation component, reducing the occupied space within the wall-mounted air conditioner 10000, and being conducive to the overall thin and light design of the wall-mounted air conditioner 10000.

[0204] Optionally, the first volute end plate 811 is a single-layer plate, making the structure simple and conducive to reducing the overall axial dimension.

[0205] In some embodiments, referring to Figure 8 , Figure 11 and Figure 14 , the exhaust air fan 7 includes: an exhaust air wheel disc 71 and exhaust air blades 72. The exhaust air wheel disc 71 is coaxially arranged with the second motor 5 and is connected to the motor housing 53 of the second motor 5. The exhaust air blades 72 are multiple pieces. The exhaust air blades 72 are arranged on the exhaust air wheel disc 71 and only extend in a direction away from the fresh air fan 6. The multiple exhaust air blades 72 are arranged circumferentially on the exhaust air wheel disc 71. That is to say, the exhaust air fan 7 includes single-layer centrifugal blades. In this way, while meeting the requirement of small air volume, the structure of the exhaust air fan 7 is simple and the cost is low. Moreover, the blade cylinder formed after the exhaust air blades 72 are arranged circumferentially is open towards the axial air inlet end, facilitating air flow inhalation, reducing the air suction resistance, and ensuring the air intake volume of the exhaust air.

[0206] In some embodiments, referring to Figure 8 , Figure 12 and Figure 14 , the fresh air fan 6 includes: a fresh air wheel disc 61 and fresh air blades 62. The fresh air wheel disc 61 is coaxially arranged with the second motor 5 and is connected to the output shaft 532 of the second motor 5. The fresh air blades 62 include first fresh air blades 621. The first fresh air blades 621 extend from the fresh air wheel disc 61 in a direction away from the exhaust air fan 7. The blade cylinder formed after the first fresh air blades 621 are arranged circumferentially is open towards the axial air inlet end, facilitating air flow inhalation, reducing the air suction resistance, and ensuring the air intake volume of the fresh air.

[0207] Specifically, referring to Figure 8 , Figure 12 and Figure 14, the fresh air blade 62 may include a second fresh air blade 622 that extends from the fresh air wheel disc 61 toward the exhaust fan 7. In this way, the fresh air fan 6 includes double-layer centrifugal blades. Thus, in the case of meeting the large air volume requirement, the double-layer centrifugal blade structure design helps to increase the overall structural strength of the centrifugal fan.

[0208] In some embodiments, in the axial direction of the fresh air fan 6, the first fresh air blade 621 is located between the second fresh air blade 622 and the fresh air inlet 801. The first fresh air blade 621 extends from the fresh air wheel disc 61 in a direction away from the exhaust fan 7, and the second fresh air blade 622 extends from the fresh air wheel disc 61 in a direction toward the exhaust fan 7. In other words, the second fresh air blade 622 extends from the fresh air wheel disc 61 in a direction away from the heat exchange fan 41. In the axial direction of the fresh air fan 6, the extending directions of the first fresh air blade 621 and the second fresh air blade 622 are opposite. In the axial direction of the fresh air fan 6, the first fresh air blade 621 is located between the second fresh air blade 622 and the fresh air inlet 801. After the outdoor air enters the fresh air volute 8 from the fresh air inlet 801, it first reaches the first fresh air blade 621 and then reaches the second fresh air blade 622. In this way, when the fresh air fan 6 rotates, a vortex is first generated at the first fresh air blade 621, and then a vortex is generated at the second fresh air blade 622. By arranging the fresh air blades 62 on both sides of the fresh air wheel disc 61, the fresh air wheel disc 61 is farther away from the inner wall of the fresh air volute 8. When the second motor 5 drives the fresh air fan 6 to rotate, the first fresh air blade 621 pushes the air to move, so a vortex will be generated around the first fresh air blade 621, and the second fresh air blade 622 pushes the air to move, so a vortex will be generated around the second fresh air blade 622. The vortices generated at the first fresh air blade 621 and the second fresh air blade 622 are superimposed on each other, which can reduce the vortex noise.

[0209] Further, a wheel disc hole 612 is formed on the fresh air wheel disc 61 for the side of the second fresh air blade 622 to suck air through the wheel disc hole 612. The distance from the wheel disc hole 612 to the center of the fresh air wheel disc 61 is less than the distance from the fresh air blade 62 to the center of the fresh air wheel disc 61. That is to say, the wheel disc hole 612 is closer to the center of the fresh air wheel disc 61 than the fresh air blade 62. This is beneficial for the second fresh air blade 622 to guide the air flow to be axially sucked into the space where the second fresh air blade 622 is located when sucking air from the wheel disc hole 612, and reduce the turbulent flow generated by competing for air with the first fresh air blade 621.

[0210] In some specific embodiments, referring to Figure 5 、 Figure 8 and Figure 15, the second volute 82 includes: a second volute half 821 and a blower housing 822. The second volute half 821 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 is provided with an axial ventilation opening 8211 at the center in the radial direction. A volute chamber V011 is formed between the second volute half 821 and the first volute 81. The fresh air fan 6 is located in the volute chamber V011. The axial air inlet end of the fresh air fan 6 is arranged facing the axial ventilation opening 8211. The second volute half 821 and the first volute 81 enclose a fresh air outlet 802.

[0211] The blower housing 822 is located on the side of the second volute half 821 facing the heat exchange fan 41 and is detachably connected to the second volute half 821. Refer to Figure 8 , the cavity enclosed by the blower housing 822 and the second volute half 821 is a fresh air chamber V012, and the blower housing 822 and the second volute half 821 enclose a fresh air inlet 801.

[0212] After being arranged like this, a fresh air chamber V012 is formed at the air inlet end of the fresh air fan 6. The formed fresh air chamber V012 can cover the axial air inlet end of the fresh air fan 6, and the fresh air chamber V012 can be used to accommodate air, so that the air can enter the fresh air fan 6 vertically along the axis from the fresh air chamber V012, thereby improving the air suction efficiency of the fresh air fan 6 and reducing the air suction loss.

[0213] Among them, the blower housing 822 is located on the side of the second volute half 821 facing the indoor heat exchanger 2, so that the volute chamber V011 can be separated from the indoor heat exchanger 2. When the indoor heat exchanger 2 cools, the indoor heat exchanger 2 can absorb the heat in the fresh air chamber V012, gradually reducing the fresh air temperature. And due to the separation of the blower housing 822, the indoor heat exchanger 2 is far from the volute chamber V011, and the cooling capacity of the indoor heat exchanger 2 to the air in the volute chamber V011 decreases, and the air in the volute chamber V011 is not likely to be supercooled to generate condensed water.

[0214] In this way, even if the inhaled fresh air is cooled, it will not be supercooled to generate condensed water. Moreover, even if condensed water is generated in the fresh air chamber V012, the condensed water is likely to remain in the fresh air chamber V012 and is not likely to enter the volute chamber V011 and then be blown into the room, avoiding the situation of the fresh air module blowing water. When the indoor heat exchanger 2 heats, the indoor heat exchanger 2 can absorb the cold in the fresh air chamber V012, gradually increasing the fresh air temperature. Subsequently, the heated air enters the volute chamber V011 and is fully mixed, making the hot air blown out from the fresh air module milder.

[0215] In some embodiments, refer to Figure 3 , the wall-mounted air conditioner 10000 further includes: a purification member 11, refer to Figure 8, the purification component 11 is arranged in the fresh air duct V01, so that the fresh air blown into the room is purified, and the cleanliness of the indoor air is improved.

[0216] Specifically, the purification component 11 is installed in the fresh air cavity V012, that is to say, the purification component 11 is located at the axial air inlet end of the fresh air fan 6. When the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can be blown through the purification component 11 and then enter the room from the fresh air outlet 802.

[0217] In this way, the fresh air flow can almost vertically pass through the purification component 11, the fresh air inlet consumption can be further reduced, and thus the fresh air volume can be increased. Moreover, when the indoor heat exchanger 2 is in the refrigeration state and condensed water is generated in the fresh air, the condensed water can stay on the purification component 11 when the air flows through the purification component 11, further avoiding the situation of water blowing when the fresh air module blows out air.

[0218] Furthermore, the purification component 11 is connected to the second volute 82, which is convenient for the assembly of the purification component 11 and does not interfere with the fresh air fan 6.

[0219] Optionally, as Figure 15 shown, the purification component 11 includes a filter net 111, and the filter net 111 covers the axial ventilation opening 8211. The filter net 111 covers the entire air inlet end of the fresh air fan 6. The filter net 111 has a large covering area, a large filtering area, and a good filtering effect. The setting of the filter net 111 helps to ensure sufficient contact area with the flowing air, and has a light weight and low air passing noise. Optionally, the filter net 111 is a HEPA net, so it has a strong adsorption force and a strong filtering effect on dust in the air.

[0220] Optionally, the filter net 111 is plate-shaped, so that the overall filter net 111 is relatively thin and will not occupy too thick a size when placed in the two-way ventilation component.

[0221] Optionally, the filter net 111 is square, which is convenient for the positioning and installation of the filter net 111.

[0222] Furthermore, the filter net 111 is a square net, and the side length of the filter net 111 is greater than the diameter of the axial ventilation opening 8211. The square net is convenient for positioning during fixation, is not easy to shake after fixation, and is easy to process with less processing waste. Making the side length of the filter net 111 greater than the diameter of the axial ventilation opening 8211 enables all the fresh air flows entering the axial ventilation opening 8211 to flow through the filter net 111, with a high filtering cleanliness.

[0223] Even further, referring to Figure 8, a part of the fresh air cavity V012 constitutes an empty cavity V0121. The cavity V0121 is located on the side of the purification component 11 away from the fresh air fan 6, and the fresh air inlet 801 communicates with the cavity V0121.

[0224] That is to say, the purification component 11 is arranged at a position in the fresh air cavity V012 close to the fresh air fan 6, and the part of the fresh air cavity V012 away from the fresh air fan 6 is the cavity V0121, that is, the cavity V0121 is between the oncoming wind of the purification component 11 and the inner surface of the fan cover 822. In this way, when the fresh air fan 6 operates, the cavity V0121 is in a negative pressure state, enabling the air flow to automatically flow into the cavity V0121 from the fresh air inlet 801, reducing the air flow resistance.

[0225] The cavity V0121 is equivalent to the air inlet negative pressure cavity of the fresh air fan 6. The setting of the air inlet negative pressure cavity has many advantages:

[0226] First, improve the air inlet efficiency. Specifically, by setting the negative pressure cavity, the buffer space on the air suction side of the fresh air fan 6 is increased, making it easier for the fresh air fan 6 to suck air, thereby increasing the air intake of the fresh air fan 6. Moreover, due to the existence of the negative pressure cavity, the fresh air is buffered and adjusted in the negative pressure cavity before entering the fresh air fan 6, reducing the fluctuation and turbulence of the fresh air flow, which is beneficial to improving the air inlet stability of the fresh air fan 6. If there is no cavity V0121 and no buffer space, the flow resistance will increase, and the operating power consumption of the fresh air fan 6 will rise.

[0227] Second, optimize the air flow distribution. Specifically, through the buffering and guiding of the negative pressure cavity, it is beneficial to guide the air flow to be sucked into the fresh air fan 6 along the axis.

[0228] Third, reduce the air flow impact and absorb noise.

[0229] In this way, while increasing the air intake of the fresh air module, it is beneficial to the overall air inlet reliability and stability.

[0230] In some embodiments, the fan cover 822 forms a positioning convex bump 8221 on the side facing the indoor heat exchanger 2. The base 3 has an end plate 31 at one end adjacent to the fan cover 822. The end plate 31 is used to install the indoor heat exchanger 2 and the heat exchange fan 41. A positioning recess 311 is formed on the end plate 31. The positioning convex bump 8221 and the positioning recess 311 are inserted and matched with each other so that the fan cover 822 and the base 3 overlap at least partially in the transverse direction.

[0231] In this way, on the one hand, the positioning convex bump 8221 and the positioning recess 311 are inserted and matched with each other to form the positioning of the two-way ventilation component. On the other hand, the overall transverse dimension can be reduced, so that the wall-mounted air conditioner 10000 will not be too long.

[0232] In some embodiments, an installation opening 803 is further provided on the fresh air volute 8, and the purification member 11 is detachably assembled within the installation opening 803. This facilitates the disassembly of the purification member 11 when it is damaged or saturated, facilitating maintenance or replacement.

[0233] Specifically, as Figure 15 shown, the installation opening 803 is formed between the blower housing 822 and the second volute half 821, and the purification member 11 is detachably assembled within the fresh air chamber V012 through the installation opening 803. In this way, the size of the installation opening 803 can be set relatively large, facilitating the installation of a purification member 11 with a relatively large size. When the size of the installation opening 803 is large, the installation opening 803 is formed by enclosing between the blower housing 822 and the second volute half 821, and the blower housing 822 and the second volute half 821 respectively form open half-ports, which is convenient for processing or demolding and has a low forming rejection rate.

[0234] Specifically, as Figure 3 shown, in the front-back direction of the main body, the installation opening 803 is located on the front side of the main body 1000. When the purification member 11 is disassembled, it can be free from the interference of the pipes connected to the fresh air inlet 801 and the exhaust outlet 902, facilitating the operation during disassembly. Optionally, a switchable panel (not shown in the figure) is provided on the front side of the housing 1. When the panel is opened or rotated upward, the installation opening 803 can be exposed, facilitating the disassembly of the purification member 11.

[0235] It is not excluded that in some solutions, the installation opening 803 is provided at the bottom of the main body 1000.

[0236] In some embodiments, as Figure 6 shown, a purification air inlet 804 for communicating with the room is formed on the fresh air volute 8. When the fresh air fan 6 rotates, indoor air can enter the fresh air volute 8 from the purification air inlet 804 to be purified by the purification member 11, and the indoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. In this way, indoor air can enter the fresh air duct V01 from the purification air inlet 804, be purified, and then enter the room from the fresh air outlet 802.

[0237] With such a setting, when the indoor air is dirty, the circulation of indoor air can be realized, and purification can be carried out during the circulation. In this way, without introducing outdoor fresh air, the indoor air can be purified, improving the cleanliness. Since no outdoor fresh air is introduced, cold or hot air that has not been heat-exchanged outdoors will not be suddenly blown into the room during indoor air purification, avoiding discomfort caused by a sharp change in indoor temperature.

[0238] Specifically, as Figure 6As shown, the purification air inlet 804 is located at the bottom of the fresh air volute 8 and is oriented downward. It can be understood that the fresh air inlet 801 is located below the main body 1000. Both the fresh air inlet 801 and the purification air inlet 804 are located at the bottom of the fresh air volute 8 and are oriented downward, which is convenient for processing and forming. Moreover, during use, one of them is selected to be opened. At this time, both the fresh air inlet 801 and the purification air inlet 804 are placed at the bottom of the fresh air volute 8, which is convenient for centrally arranging switches to select one of the air inlets to open and reducing the number of switches.

[0239] Furthermore, as Figure 6 shown, the air inlet direction of the purification air inlet 804 is perpendicular to the length direction of the main body 1000. It can be understood that by making the air inlet direction of the purification air inlet 804 perpendicular to the length direction of the main body 1000, the air suction area of the purification air inlet 804 is far from the exhaust air inlet 901, avoiding excessive air suction energy consumption caused by the purification air inlet 804 being too close to the exhaust air inlet 901. Moreover, the different directions of the purification air inlet 804 and the exhaust air inlet 901 help to expand the negative pressure area, which helps a large amount of indoor air to flow into the negative pressure area and ensures the exhaust air volume and the fresh indoor air volume.

[0240] In some embodiments, as Figure 5 and Figure 8 shown, the exhaust air volute 9 includes a wind guiding ring 91. The wind guiding ring 91 is in the shape of a circular tube, and the diameter of the wind guiding ring 91 gradually decreases in the direction towards the heat exchange exhaust fan 7. The area surrounded by the wind guiding ring 91 forms the exhaust air inlet 901. The setting of the wind guiding ring 91 can effectively collect the dispersed air flow, converge it into a relatively concentrated air flow and send it into the exhaust fan 7, making the air inlet smoother and more efficient and increasing the air inlet volume of the exhaust fan 7.

[0241] Moreover, after reasonably designing the shape and angle of the wind guiding ring 91, the air flow can enter the exhaust blades 72 of the exhaust fan 7 at the best angle, improving the working efficiency of the exhaust fan 7. When there is an unstable air flow fluctuation being inhaled, the wind guiding ring 91 can play a role in stabilizing the air flow, reducing the turbulence and fluctuation of the air flow, enabling the exhaust fan 7 to operate more smoothly. It can reduce noise and vibration and extend the service life of the exhaust fan 7.

[0242] Specifically, as Figure 8 shown, the exhaust fan 7 includes an exhaust wheel disc 71 and exhaust blades 72. The exhaust wheel disc 71 is connected to the motor housing 53 of the second motor 5. The exhaust blades 72 are connected to the side of the exhaust wheel disc 71 far from the heat exchange fan 41. The exhaust blades 72 are multiple and arranged circumferentially.

[0243] As Figure 8 and Figure 11As shown, the edge of the exhaust blade 72 away from the exhaust wheel disc 71 is the blade side edge 721. The distance between the part of the blade side edge 721 close to the second motor 5 and the exhaust wheel disc 71 decreases, and all the exhaust blades 72 form a side edge depression 73 at the place where the distance of the blade side edge 721 decreases. The end of the air guide ring 91 is located within the side edge depression 73.

[0244] That is to say, the exhaust blades 72 of the exhaust fan 7 are concave blades, and both the air guide ring 91 and the concave blades are recessed towards the fresh air fan 6. The air guide ring 91 partially enters the side edge depression 73 formed by the concave blades. With such a setting, the air guide ring 91 and the exhaust fan 7 can have partial overlap in the axial direction, and it is not necessary to increase the axial dimension of the exhaust volute 9 on the premise of setting the air guide ring 91.

[0245] In some embodiments, the accommodation cavity V1 in the main body 1000 is partitioned into a first chamber V11 and a second chamber V12, as Figure 2 shown by the dashed line frame in the figure. The indoor heat exchanger 2 is located in the first chamber V11, and the two-way ventilation component is at least partially arranged in the second chamber V12. The heat exchange air inlet 101 and the heat exchange air outlet 102 on the casing 1 are correspondingly arranged for the first chamber V11, and the casing air inlet 103 and the casing air outlet 105 on the casing 1 are correspondingly arranged for the second chamber V12.

[0246] With such a setting, the accommodation cavity V1 is partitioned into the first chamber V11 and the second chamber V12. The internal air flow in the second chamber V12 will not be affected by the driving of the heat exchange fan 41. The exhaust air inlet 901 can directly intake air from the second chamber V12, and there is no need to connect pipes between the casing air inlet 103 and the exhaust air inlet 901. This not only reduces the space occupied by the pipe body, but also the position of the casing air inlet 103 can be flexibly selected.

[0247] In the solution of the present application, a vertically arranged partition plate can be arranged in the casing 1 to separate the first chamber V11 and the second chamber V12, or the first chamber V11 and the second chamber V12 can be separated by the fresh air volute 8 or the base 3, or the cooperation of the two.

[0248] For example, in some specific embodiments as Figure 4 shown, the indoor heat exchanger 2 and the heat exchange fan 41 are installed on the base 3. End plates 31 are respectively arranged at the two transverse ends of the base 3. The two ends of the indoor heat exchanger 2 are installed on the two end plates 31, and the two ends of the heat exchange fan 41 are installed on the two end plates 31.

[0249] Optionally, the end plate 31 adjacent to the fresh air volute 8 is set as a solid plate. Through the cooperation of this end plate 31 and the inner wall of the casing 1, the accommodation cavity V1 is partitioned into the first chamber V11 and the second chamber V12. With such a setting, the setting of the partition plate can be saved. At this time, the two-way ventilation component can be installed on the adjacent end plate 31. Or optionally, asFigure 4 As shown, the blower housing 822 forms a positioning boss 8221 on the side facing the indoor heat exchanger 2. The base 3 has an end plate 31 at one end adjacent to the blower housing 822. The positioning boss 8221 and the positioning recess 311 are inserted and matched with each other, so that after the blower housing 822 is matched with the adjacent end plate 31, the positioning recess 311 is blocked, and thus the accommodation cavity V1 is divided into a first chamber V11 and a second chamber V12.

[0250] In some embodiments, the housing 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 housing air inlet 103 located on the top wall of the main body 1000 is not easily visible to people's sight, so that the appearance of the main body 1000 can be kept beautiful.

[0251] In some embodiments, the wall-mounted air conditioner 10000 further includes an electric control box 13. The electric control box 13 is located at the lateral end of the heat exchange fan 41, and the two-way ventilation component is located at the other lateral end of the heat exchange fan 41. That is to say, the two-way ventilation component and the electric control box 13 are located at the lateral two ends of the heat exchange fan 41, and the operation of the two-way ventilation component has less interference with the electric control box 13.

[0252] In other embodiments, the wall-mounted air conditioner 10000 further includes an electric control box 13. The electric control box 13 and the two-way ventilation component are located at the same lateral end of the heat exchange fan 41, and the electric control box 13 is located on the top of the two-way ventilation component. Such a setting further facilitates controlling the length of the wall-mounted air conditioner 10000.

[0253] In some embodiments, in the height direction of the main body 1000, both the fresh air inlet 801 and the exhaust air outlet 902 are located below the main body 1000, and the opening directions of the fresh air inlet 801 and the exhaust air outlet 902 are both downward. The fresh air volute 8 protrudes downward at the fresh air inlet 801 for connecting the fresh air inlet pipe 141. Outdoor air can reach the fresh air inlet 801 through the fresh air inlet pipe 141. Connecting the fresh air inlet pipe 141 to the part where the fresh air volute 8 protrudes downward at the fresh air inlet 801 facilitates the connection operation and can avoid interference between the fresh air inlet pipe 141 and other parts of the fresh air volute 8.

[0254] In some embodiments, referring to Figure 16 、 Figures 21 - 23As shown, the wall-mounted air conditioner 10000 may further include: a fresh air valve 122, which is installed inside the fresh air volute 8 and is used to open or close the fresh air inlet 801. When the fresh air valve 122 opens the fresh air inlet 801 and the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. When the fresh air valve 122 closes the fresh air inlet 801, outdoor air cannot enter the fresh air volute 8 from the fresh air inlet 801, and the air inside the fresh air volute 8 cannot be discharged to the outside through the fresh air inlet 801. By controlling the state of the fresh air valve 122, the opening or closing of the fresh air inlet 801 can be achieved.

[0255] By installing the fresh air valve 122 inside the fresh air volute 8, it is not necessary for the components outside the fresh air volute 8 to consider avoiding the fresh air valve 122. The operation of opening and closing the fresh air inlet 801 by the fresh air valve 122 will not touch the components outside the fresh air volute 8, and the fresh air volute 8 has a protective effect on the fresh air valve 122, which is beneficial to extending the service life of the fresh air valve 122.

[0256] In some embodiments, as shown in Figure 16 As shown, the wall-mounted air conditioner 10000 may further include: an exhaust valve 152, which is installed inside the exhaust volute 9 and is used to open or close the exhaust outlet 902. When the exhaust valve 152 opens the exhaust outlet 902 and the exhaust fan 7 rotates, indoor air can enter the exhaust volute 9 from the exhaust inlet 901, and the indoor air entering the exhaust volute 9 can be discharged to the outside through the exhaust outlet 902. When the exhaust valve 152 closes the exhaust outlet 902, the indoor air inside the exhaust volute 9 cannot be discharged to the outside through the exhaust outlet 902, and outdoor air cannot enter the room through the exhaust outlet 902. By controlling the state of the exhaust valve 152, the opening or closing of the exhaust outlet 902 can be achieved.

[0257] By installing the exhaust valve 152 inside the exhaust volute 9, it is not necessary for the components outside the exhaust volute 9 to consider avoiding the exhaust valve 152. The operation of opening and closing the exhaust inlet 901 by the exhaust valve 152 will not touch the components outside the exhaust volute 9, and the exhaust volute 9 has a protective effect on the exhaust valve 152, which is beneficial to extending the service life of the exhaust valve 152.

[0258] When the wall-mounted air conditioner 10000 is turned off, the wall-mounted air conditioner 10000 does not work, the fresh air valve 122 closes the fresh air inlet 801, and the exhaust valve 152 closes the exhaust air outlet 902 to prevent outdoor air from entering the room through the fresh air inlet 801 and the exhaust air outlet 902, and prevent the indoor air from exchanging with the outdoor air through the two-way ventilation component.

[0259] In the related art, people's requirements for fresh air are constantly increasing, and the demand for fresh air volume is getting larger and larger. When the traditional air intake and exhaust module introduces outdoor fresh air into the room, it will also discharge the indoor air to the outside, resulting in large fluctuations in indoor temperature and affecting the user experience. When the two-way ventilation component of the wall-mounted air conditioner 10000 of the present application is in the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, and the exhaust valve 152 closes the exhaust air outlet 902. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, the outdoor air enters the fresh air duct V01 through the fresh air inlet 801, and then blows into the room through the fresh air outlet 802. The exhaust fan 7 only idles in the exhaust volute 9. Since the exhaust duct V02 is closed at the exhaust air outlet 902, the air in the exhaust duct V02 does not flow, which will reduce the operating noise of the two-way ventilation component. At the same time, the indoor air cannot be discharged to the outside through the exhaust air outlet 902, so that the indoor temperature changes little and the user experience is better.

[0260] In the related art, people's requirements for fresh air are constantly increasing, and the demand for fresh air volume is getting larger and larger. In low-temperature or high-temperature weather, such as in winter and summer, when the outdoor fresh air is introduced into the room, due to the large temperature difference between the indoor and outdoor air, the outdoor fresh air entering the room will cause large fluctuations in the indoor temperature and affect the user experience. When the two-way ventilation component of the wall-mounted air conditioner 10000 of the present application is in the exhaust mode, the fresh air valve 122 closes the fresh air inlet 801, and the exhaust valve 152 opens the exhaust air outlet 902. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, the indoor air enters the exhaust duct V02 through the exhaust air inlet 901, and then blows to the outside through the exhaust air outlet 902. The fresh air fan 6 only idles in the fresh air volute 8. Since the fresh air duct V01 is closed at the fresh air inlet 801, the air in the fresh air duct V01 does not flow, which will reduce the operating noise of the two-way ventilation component. At the same time, the air in this room is discharged to the outside, and the air in this room is replenished by the air in the other rooms. Since the temperature difference between the air in the other rooms and the air in this room is small, the indoor temperature changes little and the user experience is better.

[0261] When the two-way ventilation component of the wall-mounted air conditioner 10000 is in the exhaust-fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, and the exhaust valve 152 opens the exhaust air outlet 902. The exhaust-fresh air mode can be turned on when the temperature difference between the indoor and outdoor air is small to meet the user's multi-scenario needs. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, the outdoor air enters the fresh air duct V01 through the fresh air inlet 801, and then blows into the room through the fresh air outlet 802. The indoor air enters the exhaust duct V02 through the exhaust air inlet 901, and then blows to the outside through the exhaust air outlet 902.

[0262] In some embodiments, the two-way ventilation component has a fresh air inlet 801 and an exhaust air outlet 902. The fresh air valve 122 is used to open or close the fresh air inlet 801, and the exhaust valve 152 is used to open or close the exhaust air outlet 902. The wall-mounted air conditioner 10000 has a fresh air mode, an exhaust mode, and an exhaust-fresh air mode.

[0263] In the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801 and the exhaust valve 152 closes the exhaust air outlet 902.

[0264] In the exhaust mode, the fresh air valve 122 closes the fresh air inlet 801 and the exhaust valve 152 opens the exhaust air outlet 902.

[0265] In the exhaust-fresh air mode, the fresh air valve 122 opens the fresh air inlet 801 and the exhaust valve 152 opens the exhaust air outlet 902.

[0266] According to the embodiment of the present application, the wall-mounted air conditioner 10000 can control the opening and closing of the fresh air inlet 801 by setting the fresh air valve 122, and can control the opening and closing of the exhaust air outlet 902 by setting the exhaust valve 152, so that the fresh air and exhaust processes of the wall-mounted air conditioner 10000 are controllable.

[0267] In some embodiments, referring to Figure 16 、 Figure 23 As shown, the wall-mounted air conditioner 10000 further includes a fresh air valve motor 121. The fresh air motor is installed in the fresh air volute 8 and is used to drive the fresh air valve 122 to open or close the fresh air inlet 801. In other words, the fresh air motor provides power for the action of the fresh air valve 122 to open or close the fresh air inlet 801.

[0268] In some embodiments, referring to Figures 16 - 19As shown, the fresh air valve motor 121 includes a fresh air motor body 1211 and a fresh air motor shaft 1212. The fresh air motor body 1211 is installed outside the fresh air volute 8. In this way, the fresh air motor body 1211 does not occupy the internal space of the fresh air volute 8, nor does it occupy the space of the fresh air duct V01, and thus does not affect the air volume in the fresh air duct V01. The fresh air motor shaft 1212 is rotatably provided in the fresh air motor body 1211. The fresh air motor shaft 1212 at least partially extends into the fresh air volute 8, and the fresh air motor shaft 1212 is used to drive the fresh air valve 122 to open or close the fresh air inlet 801. Specifically, the fresh air motor shaft 1212 is rotatable relative to the fresh air motor body 1211. When the fresh air motor shaft 1212 rotates, it can drive the fresh air valve 122 to act, so that the fresh air valve 122 opens or closes the fresh air inlet 801.

[0269] In some embodiments, the fresh air valve 122 is a baffle. The fresh air valve motor 121 is used to drive the fresh air valve 122 to move. The moving direction of the fresh air valve 122 is perpendicular to the axial direction of the second motor 5, and the axial direction of the fresh air valve motor 121 is parallel to the axial direction of the second motor 5. Refer to Figures 1 - 4 、 Figure 16 、 Figures 21 - 23 As shown, the moving direction of the fresh air valve 122 is the front-back direction of the main body 1000, so that the space of the two-way ventilation component in the front-back direction of the main body 1000 can be fully utilized; the axial directions of both the fresh air valve motor 121 and the second motor 5 are the left-right direction of the main body 1000, which facilitates the fresh air motor shaft 1212 to drive the fresh air valve 122 to move in the front-back direction.

[0270] In some embodiments, refer to Figures 1 - 4 、 Figure 16 、 Figures 21 - 23 As shown, the air inlet direction of the fresh air inlet 801 is perpendicular to the axial direction of the fresh air valve motor 121, and the moving direction of the fresh air valve 122 is perpendicular to the air inlet direction of the fresh air inlet 801. Specifically, the air inlet direction of the fresh air inlet 801 is the bottom-up direction, and the moving direction of the fresh air valve 122 is the front-back direction of the main body 1000. In this way, the fresh air valve 122 can open or close the fresh air inlet 801 within the shortest moving distance range, which is beneficial to energy conservation.

[0271] In some embodiments, refer to Figure 16 、 Figures 21 - 23As shown, the fresh air valve motor 121 and the fresh air valve 122 are connected to each other through a fresh air transmission mechanism 123. The fresh air transmission mechanism 123 includes a fresh air gear 1231 and a fresh air rack 1232. The fresh air gear 1231 is located inside the fresh air volute 8, and the fresh air gear 1231 is coaxially arranged with the fresh air motor shaft 1212. The fresh air motor shaft 1212 drives the fresh air gear 1231 to rotate, and the fresh air rack 1232 is fixed on the fresh air valve 122. The wind rack 1232 is fixed to the side of the fresh air valve 122 facing the fresh air gear 1231, so that the fresh air gear 1231 and the fresh air rack 1232 are directly engaged. The length direction of the fresh air rack 1232 is perpendicular to the axial direction of the second motor 5. The fresh air gear 1231 and the fresh air rack 1232 are engaged, so that the fresh air valve motor 121 drives the fresh air valve 122 to translate in the length direction of the fresh air rack 1232 when the fresh air gear 1231 rotates.

[0272] Specifically, the length direction of the fresh air rack 1232 is the front-to-back direction of the main body 1000, and the moving direction of the fresh air valve 122 is the same as the length direction of the fresh air rack 1232. When the fresh air gear 1231 rotates, it drives the fresh air rack 1232 to move along the length direction of the fresh air rack 1232, and when the fresh air rack 1232 moves, it drives the fresh air valve 122 to move synchronously.

[0273] Optionally, the fresh air rack 1232 and the fresh air valve 122 can be fixedly connected by bolt assembly, welding, bonding, etc.; or optionally, the fresh air rack 1232 can also be integrally formed with the fresh air valve 122, which can reduce the assembly steps between the fresh air rack 1232 and the fresh air valve 122 and reduce the number of parts.

[0274] The fresh air transmission mechanism 123 in the form of the fresh air gear 1231 and the fresh air rack 1232 has a simple structure and reliable power transmission. The fresh air gear 1231 is directly mounted on the fresh air motor shaft 1212, and no intermediate transmission shaft is added, which is conducive to simplifying the fresh air transmission mechanism 123 and reducing the number of parts, occupied space and cost of the fresh air transmission mechanism 123.

[0275] In some embodiments, the fresh air inlet 801 is located on the second volute 82, the fresh air motor body 1211 is installed on the second volute 82, and the fresh air motor shaft 1212 at least partially extends into the second volute 82. The fresh air motor body 1211 is located outside the second volute 82, does not occupy the space inside the second volute 82, and does not affect the air volume inside the second volute 82. The part of the fresh air motor shaft 1212 extending into the second volute 82 is used to drive the fresh air valve 122 to open or close the fresh air inlet 801.

[0276] In some embodiments, the fresh air motor body 1211 is installed on the blower housing 822. Specifically, the fresh air motor body 1211 is installed outside the blower housing 822, without occupying the space inside the blower housing 822 and without affecting the air volume inside the blower housing 822. The fresh air motor shaft 1212 extends into the blower housing 822.

[0277] In some embodiments, the fresh air gear 1231 is sleeved on the fresh air motor shaft 1212. A support hole may also be formed in the second volute half body 821, and the end of the fresh air motor shaft 1212 extends into the support hole. Thus, the rotation of the fresh air motor shaft 1212 is more stable.

[0278] In some embodiments, referring to Figure 23 As shown, the blower housing 822 includes a housing plate 8222. The housing plate 8222 includes a housing plate body 82221 and a housing plate flange 82222. The housing plate flange 82222 is connected to the housing plate body 82221, and the housing plate flange 82222 protrudes downward relative to the housing plate body 82221. The housing plate flange 82222 extends downward relative to the housing plate body 82221 to the lower part of the main body 1000. The housing plate flange 82222 and the second volute half body 821 enclose a fresh air inlet 801. By providing the housing plate flange 82222, it is convenient to connect the fresh air inlet pipe 141, and the fresh air inlet pipe 141 can be separated from the housing plate body 82221. Optionally, the fresh air inlet pipe 141 and the housing plate flange 82222 can be connected by means of a clamp, thread, etc.

[0279] The fresh air valve 122 is located on the side of the housing plate body 82221 facing away from the housing plate flange 82222. The side of the housing plate body 82221 facing away from the housing plate flange 82222 is the inside of the fresh air volute 8. In this way, the fresh air valve 122 is located inside the fresh air volute 8, and the components outside the fresh air volute 8 do not need to consider avoiding the fresh air valve 122. The operation of opening and closing the fresh air inlet 801 by the fresh air valve 122 will not touch the components outside the fresh air volute 8, and the fresh air volute 8 has a protective effect on the fresh air valve 122, which is beneficial to extending the service life of the fresh air valve 122.

[0280] Both the fresh air valve 122 and the housing plate body 82221 are configured as flat plate structures, and the fresh air valve 122 is parallel to the housing plate body 82221. When the fresh air valve 122 moves, it moves in a plane parallel to the housing plate body 82221, so as not to cause too much interference to the air volume inside the fresh air volute 8.

[0281] In some embodiments, a purification air inlet 804 for communicating with the interior is formed on the cover plate body 82221. When the fresh air valve 122 opens the purification air inlet 804 and the fresh air fan 6 rotates, indoor air can enter the fresh air volute 8 from the purification air inlet 804, and the indoor air entering the fresh air volute 8 can enter the interior from the fresh air outlet 802. That is to say, both the fresh air inlet 801 and the purification air inlet 804 are located on the cover plate body 82221, which facilitates the fresh air valve 122 to block one of the purification air inlet 804 and the fresh air inlet 801 and open the other. By moving the fresh air valve 122, the fresh air valve 122 can block the purification air inlet 804 and open the fresh air inlet 801, or the fresh air valve 122 can block the fresh air inlet 801 and open the purification air inlet 804.

[0282] In some embodiments, the purification air inlet 804 and the fresh air inlet 801 are arranged at intervals in a direction perpendicular to the axis of the second motor 5. The air inlet directions of the purification air inlet 804 and the fresh air inlet 801 are the same. The fresh air valve 122 is adapted to translate in a direction perpendicular to the axis of the second motor 5 to block one of the purification air inlet 804 and the fresh air inlet 801 and open the other. Thus, by using one fresh air valve 122, the opening and closing states of the purification air inlet 804 and the fresh air inlet 801 can be switched, so that when one of the purification air inlet 804 and the fresh air inlet 801 is open, the other is in a closed state. There is no need to set two valves, which saves the number of valves and the corresponding number of motors and is beneficial to cost reduction.

[0283] The front-back direction of the main body 1000 is perpendicular to the direction of the axis of the second motor 5. In the front-back direction of the main body 1000, the purification air inlet 804 and the fresh air inlet 801 are arranged at intervals. For example Figure 16 、 Figure 23 as shown, the purification air inlet 804 can be located in front of the fresh air inlet 801, that is, the purification air inlet 804 is located on the side of the fresh air inlet 801 away from the wall. In some other embodiments, the purification air inlet 804 can also be located behind the fresh air inlet 801, that is, the purification air inlet 804 is located on the side of the fresh air inlet 801 close to the wall.

[0284] In some embodiments, referring to Figure 8, the wall-mounted air conditioner 10000 further includes a purification component 11. The purification component 11 is installed in the fresh air chamber V012 and is connected to the second volute 82. When the fresh air valve 122 opens the fresh air inlet 801 and the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can be blown through the purification component 11 and then enter the room from the fresh air outlet 802. When the fresh air valve 122 opens the purification air inlet 804 and the fresh air fan 6 rotates, indoor air can enter the fresh air volute 8 from the purification air inlet 804, be purified by the purification component 11, and then enter the room from the fresh air outlet 802. The fresh air valve 122 selectively opens the fresh air inlet 801 or the purification air inlet 804, thereby switching between the fresh air mode and the purification mode to meet different usage requirements of users.

[0285] In some embodiments, both the fresh air inlet 801 and the purification air inlet 804 are located at the bottom of the fresh air volute 8, so that air flow can enter the interior of the fresh air volute 8 from the fresh air inlet 801 or the purification air inlet 804 from bottom to top. And because both the fresh air inlet 801 and the purification air inlet 804 are located at the bottom of the fresh air volute 8, it is possible to use a single fresh air valve 122 to achieve staged opening of the fresh air inlet 801 or the purification air inlet 804, reducing the number of valves and saving costs.

[0286] In some embodiments not shown in the figure, the fresh air valve 122 is a baffle, and the fresh air valve motor 121 is used to drive the fresh air valve 122 to rotate at the fresh air inlet 801 to open or close the fresh air inlet 801. Specifically, the fresh air motor shaft 1212 at least partially extends into the interior of the fresh air volute 8, and the fresh air motor shaft 1212 is used to drive the fresh air valve 122 to rotate at the fresh air inlet 801.

[0287] Specifically, the fresh air valve 122 is fixedly connected to the fresh air motor shaft 1212. Optionally, the fresh air valve 122 and the fresh air motor shaft 1212 are an integral part, or optionally, the fresh air valve 122 and the fresh air motor shaft 1212 are fixedly connected through assembly.

[0288] In some embodiments, there are multiple positions where the fresh air valve 122 opens the fresh air inlet 801 to adjust the air volume at the fresh air inlet 801. For example, when the fresh air valve 122 moves in a translational manner, there are multiple translational positions of the fresh air valve 122; when the fresh air valve 122 moves in a rotational manner, there are multiple rotational positions of the fresh air valve 122.

[0289] In some embodiments, referring to Figure 16 、 Figure 23As shown, the wall-mounted air conditioner 10000 further includes an exhaust valve motor 151. The exhaust motor is installed on the exhaust volute 9. The exhaust valve motor 151 is used to drive the exhaust valve 152 to open or close the exhaust air outlet 902. In other words, the exhaust motor provides power for the action of the exhaust valve 152 to open or close the exhaust air outlet 902.

[0290] In some embodiments, referring to Figures 16 - 19 、 Figure 23 As shown, the exhaust valve motor 151 includes an exhaust motor body 1511 and an exhaust motor shaft 1512. The exhaust motor body 1511 is installed outside the exhaust volute 9. In this way, the exhaust motor body 1511 does not occupy the internal space of the exhaust volute 9, nor does it occupy the space of the exhaust air duct V02, and thus does not affect the air volume in the exhaust air duct V02. The exhaust motor shaft 1512 is rotatably provided on the exhaust motor body 1511. The exhaust motor shaft 1512 is used to drive the exhaust valve 152 to open or close the exhaust air outlet 902.

[0291] In some embodiments, referring to Figures 16 - 19 、 Figure 23 As shown, the exhaust valve 152 is a baffle. The exhaust valve motor 151 is used to drive the exhaust valve 152 to rotate at the exhaust air outlet 902 to open or close the exhaust air outlet 902. Specifically, the exhaust motor shaft 1512 at least partially extends into the interior of the exhaust volute 9, and the exhaust motor shaft 1512 is used to drive the exhaust valve 152 to rotate at the exhaust air outlet 902.

[0292] Specifically, referring to Figure 19 As shown, the exhaust valve 152 is fixedly connected to the exhaust motor shaft 1512. Optionally, the exhaust valve 152 and the exhaust motor shaft 1512 are an integral part, or optionally, the exhaust valve 152 and the exhaust motor shaft 1512 are fixedly connected through assembly.

[0293] In some embodiments, referring to Figures 17 - 20 As shown, the exhaust volute 9 is provided with a first anti-rotation surface 904 and a second anti-rotation surface 905. The first anti-rotation surface 904 is located on one side of the second anti-rotation surface 905 facing the air outlet edge of the exhaust air outlet 902. The exhaust motor shaft 1512 has a shaft end protrusion 15121. When the shaft end protrusion 15121 rotates to abut against the first anti-rotation surface 904, the position of the shaft end protrusion 15121 is as shown in Figure 18In the position shown, the first anti-rotation surface 904 is used to limit the maximum angle position of the exhaust valve 152 opening the exhaust outlet 902, and when the shaft end protrusion 15121 rotates to stop the second anti-rotation surface 905, the second anti-rotation surface 905 is used to limit the position of the exhaust valve 152 closing the exhaust outlet 902. In other words, when the shaft end protrusion 15121 rotates to stop the second anti-rotation surface 905, the exhaust valve 152 closes the exhaust outlet 902; when the shaft end protrusion 15121 rotates from the position of the stop surface 905 to the first anti-rotation surface 904, the exhaust valve 152 gradually opens the exhaust outlet 902, until the shaft end protrusion 15121 rotates to stop the first anti-rotation surface 904, the rotation angle of the exhaust valve 152 is the maximum.

[0294] In some embodiments, reference Figures 17 - 20 As shown, the exhaust volute 9 is provided with an axial hole 9071 , and the exhaust motor shaft 1512 passes through the axial hole 9071 , and the first anti-rotation surface 904 and the second anti-rotation surface 905 are part of the hole wall of the axial hole 9071 .

[0295] In some embodiments, reference Figure 16 , Figure 23 As shown, the axial direction of the exhaust motor shaft 1512 is perpendicular to the axial direction of the second motor 5. Thus, the exhaust valve motor 151 can fully utilize the space in the front-to-back direction of the main body 1000.

[0296] In some embodiments, reference Figure 16 , Figure 23 As shown, the fresh air valve 122 opens or closes the fresh air inlet 801 by translation, and the exhaust valve 152 opens or closes the exhaust air outlet 902 by rotation. Specifically, the fresh air volute 8 is provided with a fresh air inlet 801 and a purified air inlet 804, both of which are provided at the bottom of the fresh air volute 8, and the opening directions of the fresh air inlet 801 and the purified air inlet 804 are both downward.

[0297] The fresh air valve 122 is set to open or close the fresh air inlet 801 by translation, so that the fresh air valve 122 can open and close the fresh air inlet 801 while taking into account the opening and closing of the purification air inlet 804. Specifically, the fresh air valve 122 closes the purification air inlet 804 while opening the fresh air inlet 801, and opens the purification air inlet 804 while closing the fresh air inlet 801. In this way, the fresh air inlet 801 and the purification air inlet 804 share the same fresh air valve 122, and there is no need to set a valve at the fresh air inlet 801 and the purification air inlet 804. In this way, the number of valves is saved, and the switching operation principle of the fresh air valve 122 for the fresh air inlet 801 and the purification air inlet 804 is simple and easy to operate.

[0298] The exhaust air valve 152 is arranged to be opened or closed by rotation, which can save the occupied space of the exhaust air valve 152, so that the structure of the exhaust air volute 9 at the exhaust air outlet 902 does not have to be made very large, and the rotation action of the exhaust air valve 152 is simple and easy to implement.

[0299] In some embodiments, referring to Figure 16 , Figure 23 As shown in the figure, the wall-mounted air conditioner 10000 further includes a fresh air valve motor 121 and an exhaust air valve motor 151. The fresh air valve motor 121 is used to drive the fresh air valve 122 to translate, and the exhaust air valve motor 151 is used to drive the exhaust air valve 152 to rotate. The axial direction of the fresh air valve motor 121 is perpendicular to the axial direction of the exhaust air valve motor 151. In this way, the layout of the fresh air valve motor 121 and the exhaust air valve motor 151 is reasonable, and the space outside the fresh air volute 8 and the exhaust air volute 9 can be fully utilized.

[0300] The axial direction of the fresh air valve motor 121 is parallel to the axial direction of the second motor 5, so that the axial direction of the fresh air valve motor 121 is perpendicular to the length extension direction of the fresh air rack 1232. In this way, when the fresh air valve motor 121 rotates, the fresh air valve motor 121 can better drive the fresh air rack 1232 to translate along the length extension direction of the fresh air rack 1232, so as to drive the fresh air valve 122 to translate synchronously.

[0301] The axial direction of the exhaust air valve motor 151 is perpendicular to the axial direction of the second motor 5. In this way, the exhaust air valve 152 can take the axis of the exhaust air valve motor 151 as the rotation center line, so as to open or close the exhaust air outlet 902.

[0302] In some embodiments, when the exhaust air valve 152 rotates outwards, that is, rotates in the air outlet direction of the exhaust air outlet 902, the exhaust air valve 152 opens the exhaust air outlet 902. In this way, when the exhaust air outlet 902 exhausts air, the wind force will not push the exhaust air valve 152 to rotate in the reverse direction, but will keep the exhaust air valve 152 in the open state.

[0303] In some embodiments, the exhaust air valve 152 is a baffle plate, the exhaust air valve motor 151 is used to drive the exhaust air valve 152 to move, the moving direction of the exhaust air valve 152 is perpendicular to the axial direction of the second motor 5, and the axial direction of the exhaust air valve motor 151 is parallel to the axial direction of the second motor 5. Referring to Figure 24 As shown in the figure, the moving direction of the exhaust air valve 152 is the front-back direction of the main body 1000, so that the space of the two-way ventilation component in the front-back direction of the main body 1000 can be fully utilized; the axial directions of the exhaust air valve motor 151 and the second motor 5 are both the left-right direction of the main body 1000, so that it is convenient for the exhaust air motor shaft 1512 to drive the exhaust air valve 152 to move in the front-back direction.

[0304] In some embodiments, reference Figure 24 As shown, the air outlet direction of the exhaust air outlet 902 is perpendicular to the axial direction of the exhaust valve motor 151, and the moving direction of the exhaust valve 152 is perpendicular to the air outlet direction of the exhaust air outlet 902. Specifically, the air outlet direction of the exhaust air outlet 902 is from top to bottom, and the moving direction of the exhaust valve 152 is the front-to-back direction of the main body 1000, so that the exhaust valve 152 can open or close the exhaust air outlet 902 within the shortest moving distance range, which is beneficial to energy saving.

[0305] In some embodiments, reference Figure 24 As shown, the exhaust valve motor 151 and the exhaust valve 152 are connected to each other through the exhaust transmission mechanism 153, and the exhaust transmission mechanism 153 includes an exhaust gear 1531 and an exhaust rack 1532. The exhaust gear 1531 is located outside the exhaust volute 9 and is coaxially arranged with the exhaust motor shaft 1512. The exhaust motor shaft 1512 drives the exhaust gear 1531 to rotate. The exhaust rack 1532 is fixed on the exhaust valve 152, and the exhaust rack 1532 is fixed to the side of the exhaust valve 152 facing the exhaust gear 1531, so that the exhaust gear 1531 and the exhaust rack 1532 are directly meshed, and the length direction of the exhaust rack 1532 is perpendicular to the axial direction of the second motor 5. The exhaust gear 1531 is meshed with the exhaust rack 1532, so that the exhaust valve motor 151 drives the exhaust valve 152 to translate in the length direction of the exhaust rack 1532 when the exhaust gear 1531 rotates.

[0306] Specifically, the length direction of the exhaust rack 1532 is the front-to-back direction of the main body 1000, and the moving direction of the exhaust valve 152 is the same as the length direction of the exhaust rack 1532. When the exhaust gear 1531 rotates, it drives the exhaust rack 1532 to move along the length direction of the exhaust rack 1532, and when the exhaust rack 1532 moves, it drives the exhaust valve 152 to move synchronously.

[0307] Optionally, the exhaust rack 1532 and the exhaust valve 152 can be fixedly connected by bolt assembly, welding, bonding, etc.; or optionally, the exhaust rack 1532 can also be integrally formed with the exhaust valve 152, which can reduce the assembly steps between the exhaust rack 1532 and the exhaust valve 152 and reduce the number of parts.

[0308] The exhaust transmission mechanism 153 in the form of the exhaust gear 1531 and the exhaust rack 1532 has a simple structure and reliable power transmission. The exhaust gear 1531 is directly mounted on the exhaust motor shaft 1512, and no intermediate transmission shaft is added, which is conducive to simplifying the exhaust transmission mechanism 153 and reducing the number of parts, occupied space and cost of the exhaust transmission mechanism 153.

[0309] In some embodiments, the exhaust air valve 152 has multiple positions for opening the exhaust air outlet 902 to adjust the air volume at the exhaust air outlet 902. For example, when the exhaust air valve 152 moves in a rotational manner, there are multiple rotational positions of the exhaust air valve 152; when the exhaust air valve 152 moves in a translational manner, there are multiple translational positions of the exhaust air valve 152.

[0310] In some embodiments, the exhaust air volute 9 includes an exhaust air volute body 906 and an exhaust air extension 907. The exhaust air extension 907 is connected to the exhaust air volute body 906. The exhaust air outlet 902 is located on the exhaust air extension 907, and the exhaust air motor body 1511 is installed outside the exhaust air extension 907. Refer to Figure 16 、 Figures 23 - 24 As shown in, the exhaust air motor body 1511 is installed on the front side of the exhaust air extension 907, thus making full use of the angular space formed between the exhaust air volute body 906 and the exhaust air extension 907.

[0311] In some embodiments, the two-way ventilation component has a fresh air inlet 801, a purification air inlet 804, and an exhaust air outlet 902. The fresh air valve 122 is used to open one of the fresh air inlet 801 and the purification air inlet 804 and close the other one of the fresh air inlet 801 and the purification air inlet 804. The exhaust air valve 152 is used to open or close the exhaust air outlet 902.

[0312] The wall-mounted air conditioner 10000 has a fresh air mode, an exhaust air - fresh air mode, an exhaust air - purification mode, and a purification mode.

[0313] In the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, closes the purification air inlet 804, and the exhaust air valve 152 closes the exhaust air outlet 902.

[0314] In the exhaust air - fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, closes the purification air inlet 804, and the exhaust air valve 152 opens the exhaust air outlet 902.

[0315] In the exhaust air - purification mode, the fresh air valve 122 opens the purification air inlet 804, closes the fresh air inlet 801, and the exhaust air valve 152 opens the exhaust air outlet 902.

[0316] In the purification mode, the fresh air valve 122 opens the purification air inlet 804, closes the fresh air inlet 801, and the exhaust air valve 152 closes the exhaust air outlet 902.
