[0062] Some embodiments of the utility model provide a wall -hanging air conditioner 10000.

[0063] Generally, the wall -hanging air conditioner 10000 is a split air conditioner, comprising an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by pipeline to transmit refrigerant, and the indoor unit comprises an indoor heat exchanger 2 and a heat exchange fan 41.

[0064] The outdoor unit comprises a compressor, an outdoor heat exchanger, an outdoor fan and a throttling device, and the connected compressor, outdoor heat exchanger, throttling device and indoor heat exchanger 2 form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit, and the outdoor heat exchanger and the indoor heat exchanger 2 respectively exchange heat with air. Some wall -hanging air conditioners 10000 can realize refrigeration mode, and some wall -hanging air conditioners 10000 can also realize heating mode.

[0065] The compressor is configured to compress the refrigerant to form high-pressure refrigerant by compressing low-pressure refrigerant.

[0066] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transmitted in the outdoor heat exchanger, for example, the outdoor heat exchanger works as a condenser in the refrigeration mode of the wall -hanging air conditioner 10000, so that the refrigerant compressed by the compressor is condensed by dissipating heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger works as an evaporator in the heating mode of the wall -hanging air conditioner 10000, so that the refrigerant after pressure reduction is evaporated by absorbing the heat of the outdoor air through the outdoor heat exchanger.

[0067] In some embodiments, the outdoor heat exchanger can comprise heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0068] The outdoor fan is configured to suck the outdoor air into the outdoor unit and send the outdoor air, which has exchanged heat with the outdoor heat exchanger, to the outside, and the outdoor fan provides power for the flow of the outdoor air.

[0069] The throttling device is connected between the outdoor heat exchanger and the indoor heat exchanger 2, and is used to adjust the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2, so as to adjust the flow rate of the refrigerant flowing 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 throttling device can be a throttling pipe, an electronic valve, etc. When the throttling device is an electronic valve, the opening degree of the throttling device is adjustable, so as to adjust the flow rate and pressure of the refrigerant flowing through the throttling device.

[0070] In some schemes, the wall-mounted air conditioner 10000 can include a four-way valve connected in the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit to make the wall-mounted air conditioner 10000 execute the cooling mode or the heating mode.

[0071] The indoor heat exchanger 2 is configured to exchange heat between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 can include heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2, so as to improve the heat exchange efficiency between the indoor air and the refrigerant.

[0072] The heat exchange fan 41 is configured to suck the indoor air into the indoor unit and send the indoor air, which has exchanged heat with the indoor heat exchanger 2, to the indoor, and the heat exchange fan 41 provides power for the flow of the indoor air.

[0073] The wall-mounted air conditioner 10000 can include a control device, which is mainly used to control the working frequency of the compressor, the opening degree of the throttling device, and some control devices can also control the rotating speed of the outdoor fan and the rotating speed of the heat exchange fan 41, etc. The control device is connected with the compressor, the throttling device, the motor driving the outdoor fan to rotate, and the common motor 42 driving the heat exchange fan 41 to rotate through data lines to transmit communication information.

[0074] The control device includes a processor, which can include a central processing unit (CPU), a microprocessor, an application specific integrated circuit (ASIC), and can be configured to perform the corresponding operations described in the control device when the processor executes the program stored in the non-transitory computer readable medium coupled to the control device.

[0075] The non-transitory computer readable storage medium can include a magnetic storage device (e.g., hard disk, floppy disk, or magnetic tape), an intelligent card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a key drive).

[0076] At present, most air conditioners are limited by volume and weight, and the functions that can be achieved are relatively limited, and usually only indoor air can be cooled or heated. If the user feels that the indoor air is relatively dirty and stuffy after turning on the air conditioner for a long time, it is necessary to open the window for ventilation, which is not only troublesome, but also the indoor cold air or warm air will quickly flow out of the window during the opening of the window, affecting the comfort of people.

[0077] Some fresh air air conditioners in the related art suck fresh air from the outside through a fresh air device and discharge indoor air through an exhaust air device. However, the heat exchange fan, the fresh air device, and the exhaust air device all need separate motors to drive, resulting in high cost and large size of the wall-mounted air conditioner.

[0078] To solve the above problems, some embodiments of the utility model provide a wall-mounted air conditioner 10000, which can reduce the overall size, reduce the number of motors, and save costs by sharing the same motor for the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6.

[0079] Here, the wall-mounted air conditioner 10000 is an indoor unit, which is usually installed on a wall, such as the upper region of an indoor wall.

[0080] The following embodiments of the wall-mounted air conditioner 10000 according to the present application will be described in detail. Figures 1-12 The wall-mounted air conditioner 10000 according to the embodiments of the present application will be described in detail.

[0081] Referring to Figures 1-3 The wall-mounted air conditioner 10000 according to the embodiments of the present application includes a main body 1000, which includes a casing 1, the inside of the casing 1 forms a receiving cavity V1, and the casing 1 forms a heat exchange air inlet 101 and a heat exchange air outlet 102. The casing 1 can play a protective role and constitute the overall appearance structure of the wall-mounted air conditioner 10000.

[0082] Generally, the casing 1 is a long strip-shaped casing. The length direction of the casing 1 is arranged along the horizontal direction, that is, the casing 1 is installed on the wall along the transverse direction. In actual products, in order to discharge condensate water, the casing 1 in some embodiments is installed on the wall along the transverse direction and forms a small angle with the horizontal plane.

[0083] Referring to Figure 2The main body 1000 further comprises an indoor heat exchanger 2 arranged in the accommodating cavity V1. As described above, the indoor heat exchanger 2 is a loop in the refrigerant circuit, and the indoor heat exchanger 2 is internally circulated with refrigerant, and is used to cool or heat the air flowing on the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is usually arranged along the length direction of the casing 1.

[0084] 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-shaped structure extending along the length direction.

[0085] Referring to Figure 2 The main body 1000 further comprises a base 3 arranged in the accommodating cavity V1. The base 3 is a mounting support structure inside the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. For example, the base 3 is formed with a volute tongue air duct V03, and the indoor air entering the casing 1 is guided in the flow direction through the volute tongue air duct V03, so as to ensure that the indoor air has a small resistance when flowing through the indoor heat exchanger 2.

[0086] Referring to Figures 2-4 The wall-mounted air conditioner 10000 further comprises a heat exchange fan 41 arranged in the volute tongue air duct V03. When the heat exchange fan 41 rotates, the air can be heat exchanged between the inside of the air conditioner and the indoor space.

[0087] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which has low noise and large air volume, and the air outlet speed of the cross-flow fan is uniformly distributed along the axial direction of the cross-flow fan, which is beneficial to increase the air supply distance and air supply range. Moreover, in the case of using the cross-flow fan and arranging the cross-flow fan along the length direction of the heat exchange fan 41, the driven air flow can flow through the entire indoor heat exchanger 2, thereby ensuring the balance of heat exchange efficiency of each position of the indoor heat exchanger 2.

[0088] By arranging the heat exchange air outlet 102 and the heat exchange air inlet 101 in the casing 1, the heat exchange fan 41 can suck the indoor air into the casing 1 when the heat exchange fan 41 operates. After the indoor air is heat exchanged with the indoor heat exchanger 2, the heat exchanged air is sent to the indoor space from the heat exchange air outlet 102.

[0089] Therefore, the adjustment of the indoor environment temperature can be realized, the indoor heat exchanger 2 can act as an evaporator to provide a refrigeration air flow towards the indoor space from the heat exchange air outlet 102, or the indoor heat exchanger 2 can act as a condenser to provide a heating air flow towards the indoor space from the heat exchange air outlet 102.

[0090] In some embodiments, the heat exchange air inlet 101 is located above the heat exchange air outlet 102 in the height direction of the main body 1000, so that the air is taken in from above and blown out from below. Here, the height direction of the main body 1000 is the up-down direction.

[0091] Specifically, the main body 1000 is usually installed on a wall, and in order to avoid interfering with people's daily life, the main body 1000 is usually hung at a high position. By setting the main body 1000 to blow out the heat exchange air from below, the heat exchange air is less likely to be blocked by the roof or the ground, so that the heat exchange air consumes less resistance during blowing and has a wide blowing range, so that the heat exchange air can flow to the entire indoor space as soon as possible, improving the heat exchange efficiency.

[0092] With reference to Figures 1-3 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102, so that the air can be taken in from above, which can avoid taking in air from the heat exchange air outlet 102 and avoid the heat exchange air being directly sucked into the heat exchange air inlet 101 after being blown out from the heat exchange air outlet 102, reducing the heat exchange air idling without participating in the indoor heat exchange process.

[0093] In some embodiments, the heat exchange air inlet 101 is located at the top of the casing 1, i.e., in an area that cannot be seen by the user, hiding the heat exchange air inlet 101, which can improve the appearance of the wall-mounted air conditioner 10000.

[0094] In some embodiments, the heat exchange air outlet 102 is located in front of the casing 1, i.e., the heat exchange air outlet 102 blows air to the front side of the main body 1000.

[0095] It can be understood that the side of the main body 1000 connected to the wall is usually called the back or rear side, and the side opposite to the rear side is called the front side, so when the heat exchange air outlet 102 is located in front of the casing 1, the air is blown away from the wall, and the blowing resistance is small and the blowing range is wide.

[0096] In some specific embodiments, the heat exchange air outlet 102 is located at the front side of the casing 1 and close to the bottom, for example, the heat exchange air outlet 102 is located at the front lower corner of the casing 1. In this case, the heat exchange air blown out by the heat exchange air outlet 102 flows forward while flowing downward, so that the heat exchange air can sink and fall on the person or object on the ground after being sent to a certain distance, so that the person or object on the ground can be in the suitable indoor environment as soon as possible.

[0097] With reference to Figure 2 , Figure 4The wall-mounted air conditioner 10000 further comprises a common motor 42, which is arranged in the accommodating cavity V1 and located at one end of the length direction of the heat exchange fan 41. In this way, the installation and maintenance of the common motor 42 are facilitated, and the overall height and thickness of the main body 1000 do not need to be increased due to the arrangement of the common motor 42.

[0098] Here, the height direction of the main body 1000 is consistent with the up-down direction, and the thickness direction of the main body 1000 is consistent with the front-rear direction. It can be understood that the wall-mounted air conditioner 10000 is generally in a long strip shape, and the length direction of the heat exchange fan 41 is the same as the length direction of the main body 1000, which is the left-right direction shown in FIG. 1. Figures 1-4

[0099] Referring to Figure 8 , the wall-mounted air conditioner 10000 further comprises a fresh air fan 6, which is an axial-inlet and radial-outlet centrifugal fan. The fresh air fan 6 is located at the other end of the length direction of the heat exchange fan 41, i.e., the fresh air fan 6 is located on the side of the heat exchange fan 41 away from the common motor 42.

[0100] Referring to Figure 3 and Figure 5 , Figure 6 , the wall-mounted air conditioner 10000 further comprises an exhaust fan 7, which is an axial-inlet and radial-outlet centrifugal fan. The exhaust fan 7 is located at the other end of the length direction of the heat exchange fan 41, i.e., the exhaust fan 7 is located on the side of the heat exchange fan 41 away from the common motor 42.

[0101] Among them, the exhaust fan 7 and the fresh air fan 6 are located at the same end of the heat exchange fan 41, and the common motor 42 drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate synchronously in the working state.

[0102] The centrifugal fan itself has the characteristics of compact structure, large air volume, low noise, and the fan noise decreases significantly when the rotating speed decreases, so the fresh air fan 6 and the exhaust fan 7 select a centrifugal fan with a smaller size to meet the demand for large air volume. The centrifugal fan has small vibration noise and is not easy to resonate with the indoor heat exchanger 2, which is conducive to reducing the overall vibration and noise of the wall-mounted air conditioner 10000.

[0103] ​The fresh air fan 6 and the exhaust air fan 7 are both centrifugal fans, and the directions of the air of the fresh air fan 6 and the exhaust air fan 7 can be reasonably arranged. For example, the fresh air fan 6 takes in air in the axial direction and discharges air in the radial direction, the exhaust air fan 7 takes in air in the axial direction and discharges air in the radial direction, the fresh air fan 6 and the exhaust air fan 7 take in air from two ends far away from each other, and then the fresh air and the exhaust air are both driven to be discharged in the radial direction. The flow paths of the fresh air and the exhaust air do not need to overlap in the axial direction, and the paths do not need to cross. This helps to reduce the design of the avoidance corner of the fresh air and exhaust air paths, reduce air resistance, energy consumption, ensure air volume, and reduce noise.

[0104] The fresh air fan 6 and the exhaust air fan 7 are both centrifugal fans, and the heat exchange fan 41, the exhaust air fan 7, and the fresh air fan 6 are all driven by the same motor. Not only does this save the number of motors, reduce the overall size, and save costs, but it also keeps the three fans stacked in the axial direction of the common motor 42.

[0105] In some embodiments, the centrifugal fan itself is relatively flat in the axial direction, and the stacking of the fresh air fan 6 and the exhaust air fan 7 can reduce the overall axial size occupied, so that the length of the main body 1000 does not need to be too long. Since the heat exchange fan 41, the exhaust air fan 7, and the fresh air fan 6 are all driven by the same motor, the three fans rotate synchronously, and the three fans are in step with each other. The fresh air fan 6 and the exhaust air fan 7 do not need to be separated by a large gap, and the axial distance between the fresh air fan 6 and the exhaust air fan 7 can be arranged to be relatively close.

[0106] The common motor 42, the heat exchange fan 41, the exhaust air fan 7, and the fresh air fan 6 are arranged in the length direction of the main body 1000, rather than in the thickness or height direction of the main body 1000, so that the main body 1000 of the wall-mounted air conditioner 10000 has a slender appearance and is thin and light.

[0107] Optionally, the common motor 42 is an external rotor motor. Optionally, the common motor 42 is an internal rotor motor.

[0108] Referring to Figures 5-12 , the wall-mounted air conditioner 10000 also includes a volute assembly. As Figure 8 shown, the volute assembly forms a fresh air air duct V01 and an exhaust air air duct V02. Referring to Figures 5-8 , the volute assembly forms a fresh air inlet 801, a fresh air outlet, an exhaust air inlet 901, and an exhaust air outlet 902. The fresh air inlet 801 and the fresh air outlet are both in communication with the fresh air air duct V01, and the exhaust air inlet 901 and the exhaust air outlet 902 are both in communication with the exhaust air air duct V02.

[0109] The fresh air fan 6 is arranged in the fresh air duct V01. The fresh air fan 6 rotates to allow outdoor air to enter the fresh air duct V01 from the fresh air inlet 801 and to allow the outdoor air in the fresh air duct V01 to enter the indoor environment from the fresh air outlet. The fresh air fan 6 is used to drive the air flow to be sucked from the fresh air inlet 801 and discharged to the indoor environment through the fresh air outlet. The operation of the fresh air fan 6 provides the driving force for the fresh air flow.

[0110] Therefore, by arranging the fresh air duct V01 in cooperation with the fresh air fan 6, when the air in the indoor environment is relatively dirty or the air quality is poor, the relatively fresh outdoor air can be driven by the fresh air fan 6 to enter the indoor environment, so as to improve the air flow environment in the indoor environment.

[0111] In the present application, the number of fresh air outlets can be one, and the number of fresh air outlets can be multiple, for example, two, three, four or more. By arranging multiple fresh air outlets, the air discharge amount can be increased.

[0112] Optionally, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in the same direction.

[0113] Alternatively, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in different directions.

[0114] In some embodiments, referring to Figure 7 , the fresh air outlet includes a first fresh air outlet 802 and a second fresh air outlet 808, and the first fresh air outlet 802 and the second fresh air outlet 808 are in communication with the fresh air duct V01. The fresh air fan 6 rotates to allow outdoor air to enter the fresh air duct V01 from the fresh air inlet 801 and to allow the outdoor air in the fresh air duct V01 to enter the indoor environment from the first fresh air outlet 802 and the second fresh air outlet 808.

[0115] The exhaust fan 7 is arranged in the exhaust air duct V02. The exhaust fan 7 rotates to allow indoor air to enter the exhaust air duct V02 from the exhaust air inlet 901 and to allow the indoor air in the exhaust air duct V02 to be discharged to the outdoor environment from the exhaust air outlet 902. The exhaust fan 7 is used to drive the air flow to be sucked from the exhaust air inlet 901 and discharged to the outdoor environment through the exhaust air outlet 902. The operation of the exhaust fan 7 provides the driving force for the dirty air flow.

[0116] Therefore, by arranging the exhaust air duct V02 in cooperation with the exhaust fan 7, when the air in the indoor environment is relatively dirty or the air quality is poor, the dirty air flow in the indoor environment can be sucked and discharged by the exhaust fan 7. After the amount of indoor air is reduced, fresh air can be sucked from the outdoor environment or from other rooms through doors and windows, so as to reduce the degree of dirtiness of the indoor air.

[0117] The fresh air fan 6, the exhaust fan 7 and the volute assembly constitute a bidirectional ventilation assembly, which is arranged in the main body 1000. The bidirectional ventilation assembly can provide fresh air for the indoor space and can exhaust indoor air to the outdoor space.

[0118] It should be noted that in the wall-mounted air conditioner 10000, the operation mode of the bidirectional ventilation assembly can be set according to actual use requirements.

[0119] In some embodiments, the bidirectional ventilation assembly can operate in the fresh air mode and the exhaust air mode at the same time, that is, the fresh air duct V01 and the exhaust air duct V02 can be opened at the same time. While the indoor dirty air flows to the outdoor space, fresh air from the outdoor space can also enter the indoor space. Through the air flow driving assembly, the improvement efficiency of the indoor space air flow is increased, so that the user demand can be met in time when the user urgently needs to exhaust or update the indoor air.

[0120] Moreover, while the indoor air is exhausted to the outdoor space, fresh outdoor air is supplemented to the indoor space, the indoor air amount is kept sufficient, and the indoor air is more easily sucked. For example, when there is a stimulating gas (such as a gas released by a home decoration material), coal gas or other gas leakage in the indoor space, the bidirectional ventilation assembly can be set to operate in the fresh air mode and the exhaust air mode at the same time, so that rapid ventilation is realized. Compared with the conventional fresh air structure that simply introduces fresh air, the bidirectional ventilation assembly in some embodiments has a larger purification flow per unit time, a higher ventilation efficiency and a better purification effect.

[0121] Moreover, when the air is exchanged, the air is not exchanged too quickly like directly opening a window, so that the indoor temperature does not change sharply and the indoor personnel are not caused to be uncomfortable due to a sharp temperature rise or a sharp temperature drop. Moreover, the main body 1000 is located at a higher position, and the ventilation position does not cause discomfort due to being too close to the people.

[0122] It can be understood that when the wall-mounted air conditioner 10000 is in a cooling state, the bidirectional ventilation assembly sucks fresh air from the outdoor space to the indoor space, and the cold energy generated by the wall-mounted air conditioner 10000 can still remain in the indoor space, so that the cold energy loss is small. The indoor air is exhausted to the outdoor space through the exhaust air duct V02. By setting the exhaust air volume to be smaller than the fresh air volume, the cold energy loss can be reduced.

[0123] The bidirectional ventilation assembly is arranged at one end in the length direction of the heat exchange fan 41. Compared with the main body without the bidirectional ventilation assembly, only the transverse length is increased, and the height and the thickness of the main body 1000 can be substantially unchanged or slightly changed. The main body 1000 is light and thin in appearance, and is hung on the wall without affecting the indoor space layout due to being too conspicuous, and is not difficult to fix due to being too heavy, so that the risk of falling from the wall is reduced. The wall-mounted air conditioner 10000 is still a light and thin model, which is not only beautiful when hung on the wall, but also controllable in weight.

[0124] In some embodiments, the fresh air fan 6 is located between the exhaust air fan 7 and the heat exchange fan 41, that is, the exhaust air fan 7 is located on the side of the fresh air fan 6 away from the heat exchange fan 41, and the exhaust air fan 7 is also relatively far away from the indoor heat exchanger 2, so that the exhaust air fan 7 can absorb less cold or heat from the indoor heat exchanger 2 after absorbing indoor air, and the loss of cold or heat to the outside is small.

[0125] In addition, the fresh air fan 6 is located between the exhaust air fan 7 and the heat exchange fan 41, and the exhaust air path can be separated from the fresh air path and the heat exchange path. The exhaust air fan 7 is farther away from the heat exchange fan 41, and the exhaust air inlet 901 is located farther away from the heat exchange inlet 101 and the heat exchange outlet 102, so that the exhaust air inlet 901 can be separated from the fresh air outlet path and the heat exchange outlet path, thereby reducing the risk of air flow short circuit.

[0126] In some embodiments, as shown in Figure 3 and Figure 5 , the exhaust air inlet 901 is located on the side of the volute assembly away from the heat exchange fan 41. That is, the exhaust air inlet 901 is opposite to the axial air inlet end of the exhaust air fan 7, so that the exhaust air fan 7 has small air resistance when it inhales air from the exhaust air inlet 901, which is conducive to ensuring the exhaust air inlet amount. When the exhaust air inlet amount is easy to control, a smaller exhaust air fan 7 can be selected to further reduce the size of the bidirectional air exchange assembly.

[0127] For example, the exhaust air inlet 901 is located on the volute assembly away from the indoor heat exchanger 2, and the air inlet area of the exhaust air inlet 901 avoids the indoor heat exchanger 2. When there is condensate water on the indoor heat exchanger 2 or the condensate water is attached to the surface of the parts near the indoor heat exchanger 2 in the accommodation cavity V1, the condensate water is not easy to be sucked into the exhaust air duct V02 by the exhaust air fan 7, which reduces the risk of water accumulation and bacterial growth in the exhaust air duct V02. When the fresh air fan 6 rotates, it basically inhales air from the outside, and at this time, the condensate water on the indoor heat exchanger 2 will not be sucked into the fresh air duct V01, which reduces the risk of water accumulation and bacterial growth in the fresh air duct V01.

[0128] In some embodiments, as shown in Figure 3 , the casing 1 is provided with a casing air inlet 103 at one end of the volute assembly, and the indoor air is brought into the interior of the casing 1 by the casing air inlet 103 when the exhaust air fan 7 rotates, and the indoor air enters the exhaust air duct V02 through the exhaust air inlet 901. In this way, the exhaust air suction path can be shortened, thereby reducing the exhaust air suction resistance and improving the exhaust air inlet amount.

[0129] Specifically, the casing air inlet 103 and the exhaust air inlet 901 do not need to be connected by a pipe, and the air flow is only sucked into the casing air inlet 103 by air pressure. The position of the casing air inlet 103 can be appropriately adjusted at the end of the casing 1, for example, can be located at the top of the casing 1, that is, in the area that cannot be seen by the user, hiding the casing air inlet 103, which can improve the appearance.

[0130] In some specific embodiments, the casing air inlet 103 is located on the side of the main body 1000 and is opposite the exhaust air inlet 901. The rotation of the exhaust fan 7 drives the indoor air to enter the inside of the casing 1 through the casing air inlet 103, and the indoor air enters the volute assembly through the exhaust air inlet 901.

[0131] In this way, on the one hand, the exhaust air inlet 901 can be close to the side of the casing 1, so that the air inlet path from the casing air inlet 103 to the exhaust air inlet 901 is shorter, and the air inlet path from the casing air inlet 103 to the exhaust air inlet 901 is generally arranged along the axial direction of the exhaust fan 7, so that when the indoor air flows along the 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 air can be further reduced to ensure the exhaust air inlet amount.

[0132] By arranging the casing air inlet 103 on the side of the main body 1000, the obstruction of the main body 1000 side is small, so that the obstruction of the exhaust air inlet outside the casing 1 is also small, which is beneficial to ensure smaller air inlet resistance and larger exhaust air inlet amount.

[0133] In addition, the exhaust air inlet position and the fresh air outlet path and the heat exchange outlet path can almost reach the farthest state under limited conditions. The heat exchange air is usually exhausted from the front side or the front lower corner of the casing 1, and the exhaust air inlet direction and the heat exchange outlet direction are almost at a 90-degree angle. At this time, the fresh air is also mostly exhausted from the front side or the front lower corner of the casing 1, and the exhaust air inlet direction and the fresh air outlet direction are also almost at a 90-degree angle. The return air short circuit situation can be avoided to the maximum extent. In this way, the probability of sucking away condensate water from the heat exchange path can also be reduced, and the possibility of breeding bacteria in the exhaust air duct V02 can be reduced.

[0134] By arranging the casing air inlet 103 on the side of the main body 1000, the visualization effect is good, and it is convenient to observe the exhaust air inlet condition and the exhaust effect from the outside.

[0135] Further, as shown in Figure 3 The casing 1 further comprises an air inlet grille 115 arranged at the casing air inlet 103. The air inlet grille 115 can prevent foreign matter from entering the exhaust air inlet 901, reducing the risk of foreign matter blocking the exhaust fan 7. In addition, the arrangement of the air inlet grille 115 can also beautify the casing air inlet 103, improving the appearance.

[0136] In some specific embodiments, as shown in Figure 5As shown, the volute assembly is mounted on the base 3. One end of the base 3 is provided with a support baffle 33 located at the side of the volute assembly away from the heat exchange fan 41.

[0137] Here, the volute assembly and the heat exchange fan 41 are both mounted on the base 3, and the same base 3 is used as a mounting frame, so that the vibration generated during operation can be transmitted to the base 3, and the base 3 can dissipate and diffuse the vibration, thereby reducing the vibration and noise. The base 3 is provided with a support baffle 33 at the side of the volute assembly away from the heat exchange fan 41, which can better support the volute assembly and better receive the vibration transmitted from the volute assembly, consume vibration energy, and reduce vibration noise.

[0138] Specifically, the support baffle 33 is an L-shaped plate arranged around the air exhaust inlet 901. In this way, the volute assembly is covered as much as possible, and the air inlet of the air exhaust inlet 901 is not affected. Moreover, the support baffle 33 is arranged around the air exhaust inlet 901, which is also conducive to the air flow on the outside of the support baffle 33 flowing along the support baffle 33 to the air exhaust inlet 901, thereby playing a role in guiding the air flow.

[0139] In some embodiments of the present application, the common motor 42 includes an output shaft, and the heat exchange fan 41 is fixedly connected to the output shaft. The output shaft rotates to drive the heat exchange fan 41 to rotate.

[0140] In some embodiments of the present application, the wall-mounted air conditioner 10000 further includes a transmission shaft, and the transmission shaft is adapted to be connected to the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6. When the output shaft drives the heat exchange fan 41 to rotate, the heat exchange fan 41 drives the exhaust fan 7 and the fresh air fan 6 to rotate synchronously through the transmission shaft. Thus, one common motor 42 drives the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 to rotate, and the number of motors is reduced, thereby saving costs.

[0141] In some embodiments of the present application, the output shaft is coaxially arranged with the transmission shaft.

[0142] In some embodiments of the present application, the transmission shaft is adapted to be formed in one piece with one of the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6, and the other two of the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 are fixedly mounted on the transmission shaft.

[0143] For example, the transmission shaft is formed in one piece with the heat exchange fan 41, and the exhaust fan 7 and the fresh air fan 6 are fixedly mounted on the transmission shaft. The transmission shaft and the heat exchange fan 41 can be fixed by welding or can be an integrally injection molded piece. The exhaust fan 7 and the transmission shaft, and the fresh air fan 6 and the transmission shaft can be non-circular surface matching or interference fitting to prevent relative rotation between the exhaust fan 7 and the transmission shaft, and between the fresh air fan 6 and the transmission shaft.

[0144] For example, the transmission shaft and the exhaust fan 7 are formed as an integral piece, and the heat exchange fan 41 and the fresh air fan 6 are fixedly installed on the transmission shaft. The transmission shaft and the exhaust fan 7 can be fixed by welding or formed as an integral injection molding piece. The heat exchange fan 41 and the transmission shaft, and the fresh air fan 6 and the transmission shaft can be non-circular surface matching or interference matching to prevent relative rotation between the heat exchange fan 41 and the transmission shaft, and between the fresh air fan 6 and the transmission shaft.

[0145] For example, the transmission shaft and the fresh air fan 6 are formed as an integral piece, and the exhaust fan 7 and the heat exchange fan 41 are fixedly installed on the transmission shaft. The transmission shaft and the fresh air fan 6 can be fixed by welding or formed as an integral injection molding piece. The exhaust fan 7 and the transmission shaft, and the heat exchange fan 41 and the transmission shaft can be non-circular surface matching or interference matching to prevent relative rotation between the exhaust fan 7 and the transmission shaft, and between the heat exchange fan 41 and the transmission shaft.

[0146] In other embodiments, the transmission shaft and the heat exchange fan 41 are detachably connected, and the exhaust fan 7 and the fresh air fan 6 are installed and connected on the transmission shaft. In the present application, the exhaust fan 7 and the fresh air fan 6 can be an integral piece, or the exhaust fan 7 and the fresh air fan 6 can be independently processed and then installed on the transmission shaft to rotate synchronously.

[0147] Alternatively, the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 are separated, and the three can be independently processed and then assembled to the common motor 42. In this way, the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 do not need to be integrally formed, which can reduce the process difficulty, and the quality of each fan is easy to guarantee, and the overall dynamic balance is easy to ensure.

[0148] By providing the transmission shaft, the transmission shaft and the heat exchange fan 41 are detachably connected, and the exhaust fan 7 and the fresh air fan 6 are installed and connected on the transmission shaft. When the heat exchange fan 41 is maintained, the exhaust fan 7 and the fresh air fan 6 do not need to be disassembled, and when the exhaust fan 7 and the fresh air fan 6 are maintained, the heat exchange fan 41 does not need to be disassembled, which can facilitate the disassembly and maintenance in the later period.

[0149] In some embodiments, as shown in FIG. 1, Figures 6-12 As shown in FIG. 1, the volute assembly includes a first half shell assembly and a second half shell assembly. The first half shell assembly is installed on the base 3, and the second half shell assembly is detachably installed on the first half shell assembly. The first half shell assembly and the second half shell assembly enclose the exhaust air duct V02, and also enclose the fresh air duct V01.

[0150] The connection line between the first and second half-shell assemblies can be perpendicular to the axes of the fresh air fan 6 and the exhaust fan 7, meaning the connection line can be parallel to the diameter lines of the fresh air fan 6 and the exhaust fan 7. Alternatively, the connection line can deviate from the diameter lines of the fresh air fan 6 and the exhaust fan 7.

[0151] Understandably, the fresh air fan 6 and exhaust fan 7 do not require a drive motor; instead, they are driven by the heat exchange fan 41. The volute assembly primarily serves to seal the air duct and does not need to support the drive motor. The volute assembly has low structural strength requirements, and dividing it into a first half-shell assembly and a second half-shell assembly does not affect its supporting function for the fresh air fan 6 and exhaust fan 7.

[0152] Mounting the first half-shell assembly on the base 3 ensures the stability of the volute assembly foundation. The second half-shell assembly is detachably mounted on the first half-shell assembly, facilitating the assembly of the volute assembly with the fresh air fan 6 and the exhaust fan 7. Furthermore, the volute assembly can be easily opened, allowing for easy disassembly by simply opening the second half-shell assembly to expose the fresh air fan 6 and the exhaust fan 7, making inspection, disassembly, and maintenance very convenient.

[0153] In the above scheme, it is equivalent to dividing the volute assembly roughly radially into a first half-shell assembly and a second half-shell assembly. In this application, if the volute assembly is to be divided into multiple parts, it can also be divided axially, thus allowing for axial assembly and disassembly.

[0154] In some specific embodiments, such as Figures 6-12 As shown, the first half-shell assembly includes a first common volute half-body 91 and a first fresh air volute half-body 85. The second half-shell assembly includes a second common volute half-body 92 and a second fresh air volute half-body 86.

[0155] Specifically, the second common volute half 92 is detachably connected to the first common volute half 91. The first common volute half 91 includes a first exhaust half 911. The second common volute half 92 includes a second exhaust half 921, which, together with the first exhaust half 911, forms an exhaust duct V02. This creates an independent exhaust duct V02, and when the second common volute half 92 is removed from the first common volute half 91, the exhaust fan 7 is directly exposed, facilitating the disassembly, inspection, and maintenance of the exhaust fan 7.

[0156] The first fresh air volute half 85 is arranged on the side of the first common volute half 91 facing the heat exchange fan 41, and the second fresh air volute half 86 is arranged on the side of the second common volute half 92 facing the heat exchange fan 41. The second fresh air volute half 86 is detachably connected with the first fresh air volute half 85, and together encloses at least part of the fresh air air duct V01. In this way, an independent fresh air air duct V01 can be formed, and when the second fresh air volute half 86 is detached from the first fresh air volute half 85, the fresh air fan 6 can directly leak out, facilitating the disassembly, maintenance and repair of the fresh air fan 6.

[0157] By dividing the volute assembly into the first common volute half 91, the second common volute half 92, the first fresh air volute half 85 and the second fresh air volute half 86 and machining them respectively, the manufacturing and assembly difficulty can be reduced, and the quality control of the complex shell after being manufactured in parts is facilitated. The first common volute half 91 and the second common volute half 92 are detachably connected, and the first fresh air volute half 85 and the second fresh air volute half 86 are detachably connected, which facilitates assembly and subsequent adjustment and maintenance.

[0158] Specifically, as shown in Figure 5 and Figure 6 , the first exhaust air half shell part 911 and the second exhaust air half shell part 921 enclose the exhaust air inlet 901, and the exhaust air outlet 902 is arranged on the first exhaust air half shell part 911. That is, the exhaust air inlet 901 is not entirely arranged on the first exhaust air half shell part 911, nor entirely arranged on the second exhaust air half shell part 921. The entire exhaust air half is divided into two parts from the exhaust air inlet 901, and each half shell part does not need to entirely enclose the exhaust air inlet 901. The exhaust air inlet 901 is an axial inlet, and the area of the exhaust air inlet 901 is usually matched with the exhaust air fan 7. A larger area of the exhaust air inlet 901 is enclosed by two exhaust air half shell parts, which can save the material for machining the half shell part. When the second exhaust air half shell part 921 is detached, the exhaust air inlet 901 is also opened, and there is more operating space for disassembly, maintenance and repair of the exhaust air fan 7, and the operation is more convenient.

[0159] Specifically, the connecting surface of the first common volute half 91 and the second common volute half 92 extends vertically through the axis of the exhaust air fan 7. In this way, the common volute part is divided into two parts along the axis of the exhaust air fan 7, and the cutout is large. The workpiece is disassembled and assembled from the opening, the operating space is large, and the disassembly and assembly are facilitated.

[0160] Specifically, as shown in Figure 7 and Figure 12As shown, the connecting surface of the first fresh air volute half 85 and the second fresh air volute half 86 extends downwards and forwards through the axis of the fresh air fan 6. Here, the first fresh air volute half 85 is fixed to the base 3, while the second fresh air volute half 86 is detachable from the first fresh air volute half 85. When the first fresh air volute half 85 is removed, a large opening facing forward and upward is exposed. Moreover, for the wall-mounted air conditioner 10000, when disassembling after installation, the operator can easily operate with the opening facing forward while standing in front of the main body 1000.

[0161] The first fresh air volute half 85 and the second common volute half 92 enclose the first fresh air outlet 802, and the second fresh air volute half 86 and the first common volute half 91 enclose the second fresh air outlet 808. In other words, the fresh air volute section has two fresh air outlets, with one outlet on each of the two fresh air volute halves. It is understandable that the shape of the fresh air outlets must be adapted to the characteristics of the centrifugal fan's airflow, especially to meet the vortex-like shape of centrifugal airflow. Therefore, placing the two fresh air outlets on the two separate fresh air volute halves reduces the processing difficulty of each fresh air volute half.

[0162] At this point, the connecting surface of the two fresh air volute halves is set to extend downwards in the forward direction, so that the two fresh air outlets can be distributed on the two fresh air volute halves.

[0163] Of course, a fresh air outlet can also be provided on only one fresh air volute half. However, compared to a volute assembly with only one fresh air outlet, the volute assembly of this application provides both a first fresh air outlet 802 and a second fresh air outlet 808, resulting in a larger air volume.

[0164] In some specific embodiments, such as Figures 6-11 As shown, the first common volute half 91 further includes a first hood half 913, which is disposed between the first exhaust half 911 and the first fresh air volute half 85. The second common volute half 92 further includes a second hood half 923, which is disposed between the second exhaust half 921 and the second fresh air volute half 86, and is detachably connected to the first hood half 913.

[0165] The fresh air duct V01 includes a connected volute cavity V011 and a fresh air cavity V012, with the fresh air cavity V012 formed between the first half-shell portion 913 and the second half-shell portion 923. The first half-shell portion 913, the second half-shell portion 923, the first fresh air volute half-body 85, and the second fresh air volute half-body 86 enclose the volute cavity V011, and the fresh air fan 6 is located inside the volute cavity V011.

[0166] That is to say, the axial air inlet end of the volute cavity V011 is also provided with a fresh air cavity V012. After being thus arranged, the fresh air cavity V012 is arranged at the air inlet end of the fresh air fan 6 to buffer the airflow, and the fresh air cavity V012 formed in this way can cover the axial air inlet end of the fresh air fan 6, and can accommodate air in the fresh air cavity V012, so that the air can enter the fresh air fan 6 vertically along the axial direction, thereby improving the air suction efficiency of the fresh air fan 6 and reducing the air suction loss.

[0167] Specifically, the fresh air cavity V012 corresponds to a negative pressure cavity of the fresh air fan 6. The negative pressure cavity can form a relatively low pressure area at the air inlet end of the fresh air fan 6, and can guide the surrounding air to flow more smoothly to the fresh air fan 6 by utilizing the pressure difference. Moreover, the airflow entering the fresh air fan 6 can be more uniform, and problems such as local airflow turbulence and uneven speed of the air inlet can be reduced. The negative pressure cavity can pre-adjust the airflow, so that the air is mixed and adjusted to a certain extent in the fresh air cavity V012 before entering the fresh air fan 6, thereby making the airflow speed and direction reaching the blades of the fresh air fan 6 more consistent, which is helpful for the fan to work more efficiently. The negative pressure cavity optimizes the inlet airflow, makes the airflow more stable, reduces the irregular impact between the airflow and the fan blades, and reduces the noise generated during the operation of the fan.

[0168] The first common volute half 91 and the second common volute half 92 are arranged in this way in the present application, so that the fresh air cavity V012 is sandwiched between the volute cavity V011 and the exhaust air duct V02, and the exhaust air inlet path and the fresh air outlet path can be separated farther away, thereby reducing the risk of airflow short circuit.

[0169] Further, as shown in Figure 6 and Figure 7 the first common volute half 91 further comprises a first fresh air half shell part 915, and the first shroud half shell part 913 is arranged on the side of the first shroud half shell part 913 facing the heat exchange fan 41, and the first fresh air half shell part 915 and the second fresh air volute half 86 jointly enclose the second fresh air outlet 808. The second common volute half 92 further comprises a second fresh air half shell part 925, and the second fresh air half shell part 925 is arranged on the side of the second shroud half shell part 923 facing the heat exchange fan 41, and the second fresh air half shell part 925 and the first fresh air volute half 85 jointly enclose the first fresh air outlet 802. In this way, the first common volute half 91 and the second common volute half 92 can be matched in shape with the first fresh air volute half 85 and the second fresh air volute half 86, and can be better connected and sealed.

[0170] Specifically, the first common volute half 91 comprises a first exhaust air half shell part 911 and a first shroud half shell part 913, and the second common volute half 92 comprises a second exhaust air half shell part 921 and a second shroud half shell part 923.

[0171] The first exhaust half shell 911 and the first shroud half shell 913 can be an integral piece, which can reduce the number of volutes and thus reduce the assembly process of the volute assembly. The first exhaust half shell 911 and the first shroud half shell 913 can also be separate pieces.

[0172] The second exhaust half shell 921 and the second shroud half shell 923 can be an integral piece, which can reduce the number of volutes and thus reduce the assembly process of the volute assembly. The second exhaust half shell 921 and the second shroud half shell 923 can also be separate pieces.

[0173] Specifically, the detachable connection between the second common volute half 92 and the first common volute half 91 can include a snap connection or a fastener connection. Optionally, the fastener can be a bolt, a screw, etc., which can firmly connect the two parts.

[0174] The detachable connection between the second fresh air volute half 86 and the first fresh air volute half 85 can include a snap connection or a fastener connection. Optionally, the fastener can be a bolt, a screw, etc., which can firmly connect the two parts.

[0175] In some embodiments, as shown in Figure 6 , Figures 10-12 At least one of the first shroud half shell 913 and the second shroud half shell 923 is provided with a fresh air inlet 801. Figure 8 As shown in

[0176] In this way, when the fresh air fan 7 rotates, the air flow is driven from the fresh air inlet 801 into the fresh air cavity V012, then enters the volute cavity V011 through the axial air inlet 8211, and is sucked into the fresh air fan 7. Finally, driven by the fresh air fan 7, it is blown out of the fresh air outlet. The air entering the fresh air inlet 801 directly enters the fresh air cavity V012 for buffering, without needing to turn from the volute cavity V011 into the fresh air cavity V012, which is conducive to further reducing the wind resistance and improving the fresh air inlet volume.

[0177] In some embodiments, as shown in Figure 2As shown, the fresh air outlet includes a first fresh air outlet 802, which is connected to the heat exchange outlet 102. This eliminates the need for a separate opening on the casing 1 for the first fresh air outlet 802, reducing the number of openings. Furthermore, the fresh air blown out from the first fresh air outlet 802 can mix with the indoor air flowing through the indoor heat exchanger 2, resulting in a more uniform temperature after mixing. This arrangement facilitates the rapid arrival of fresh air at room temperature, improving comfort during fresh air intake, and also ensures thorough mixing of the fresh air with the indoor air flowing through the indoor heat exchanger 2. This results in generally fresh air being blown into the room from the heat exchange outlet 102, improving the uniformity of fresh air distribution within the room.

[0178] In some specific embodiments, such as Figure 4 and Figure 2 As shown, the fresh air outlet includes a second fresh air outlet 808, which is located at the top of the main body 1000. The top of the housing 1 is provided with a housing outlet 105, and the second fresh air outlet 808 is connected to the housing outlet 105.

[0179] This method of directing fresh air towards the roof allows the roof to guide the airflow, expanding the air supply area. Furthermore, since the heat exchange inlet 101 is located above the heat exchange outlet 102, and its position on the casing 1 is relatively high, some of the fresh air blown from the top by the second fresh air outlet 808 can be re-inhaled into the receiving cavity V1 through the heat exchange inlet 101 and flow through the indoor heat exchanger 2.

[0180] This setup facilitates the rapid arrival of fresh air at room temperature, enhancing comfort when the fresh air is introduced. It also promotes thorough mixing of the fresh air with the indoor air flowing through the indoor heat exchanger 2, ensuring that the air blown into the room from the heat exchange outlet 102 is generally fresh and improving the uniformity of fresh air distribution within the room.

[0181] In some embodiments of this application, reference is made to Figure 2 , Figures 4-11 The wall-mounted air conditioner 10000 also includes a purification component 11, which is installed in the fresh air duct V01 to purify the fresh air blown into the room and improve the cleanliness of the indoor air.

[0182] Specifically, the purification component 11 is installed inside the fresh air cavity V012. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air cavity V012 through the fresh air inlet 801, and also allows the outdoor air entering the fresh air cavity V012 to pass through the purification component 11, then enter the volute cavity V011, and finally enter the room through the fresh air outlet. The purification component 11 is located at the axial air inlet end of the fresh air fan 6. The purification component 11 is connected to the volute assembly; its assembly must be convenient and it must not interfere with the fresh air fan 6.

[0183] In this way, the fresh air flow can almost be blown vertically through the purification component 11, and the fresh air intake consumption can be further reduced, thereby increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in a refrigeration state, causing condensate water in the fresh air, the condensate water can be left on the purification component 11 when the air flows through the purification component 11, thereby further avoiding the situation of blowing water when the fresh air device blows out.

[0184] In some embodiments of the present application, the purification component 11 comprises a filter screen, the filter screen covers the entire fresh air fan 6 Figure 8 and Figure 11 The axial air vent 8211. The filter screen covers the entire fresh air fan 6, has a large filter area, and has a good filtering effect. The setting of the filter screen helps to ensure sufficient contact area with the airflow, and has a light weight and a small airflow noise. For example, the filter screen is a Hepa screen, and thus has strong adsorption force and strong filtering effect on dust in the air.

[0185] In some embodiments of the present application, the filter screen is plate-shaped, so that the filter screen is relatively thin as a whole and does not occupy a thick size when placed in the bidirectional ventilation assembly.

[0186] In some embodiments of the present application, the filter screen is square-shaped, so that the positioning and installation of the filter screen are facilitated.

[0187] In some embodiments of the present application, the filter screen is a square screen, and the side length of the filter screen is greater than the diameter of the axial air vent 8211. The square screen is convenient to position when fixed, is not easy to shake after being fixed, and is easy to process and has less waste. The side length of the filter screen is greater than the diameter of the axial air vent 8211, so that all the fresh air flow entering the axial air vent 8211 can flow through the filter screen, and the filtering cleanliness is high.

[0188] In some specific embodiments, as shown in Figure 6 The fresh air inlet 801 is provided on the first machine cover half shell part 913, and the purification component 11 is detachably installed on the second machine cover half shell part 923. In this way, the fixing structures of the fresh air inlet 801 and the purification component 11 can be formed on the two machine cover half shell parts respectively, and the processing difficulty of a single machine cover half shell part is reduced. Moreover, the first machine cover half shell part 913 is provided between the first air exhaust half shell part 911 and the first fresh air volute half body 85, and the first machine cover half shell part 913 can remain undetached when the centrifugal fan is disassembled, and only the second machine cover half shell part 923 is detached. Therefore, when the fresh air inlet 801 is provided on the first machine cover half shell part 913 and the centrifugal fan needs to be disassembled, the fresh air inlet 801 does not affect the connection of the pipeline, the disassembly interference is small, and the disassembly is more convenient.

[0189] Specifically, when the connecting surfaces of the first common volute half 91 and the second common volute half 92 extend vertically through the axis of the exhaust fan 7, the second hood half 923 can be removed forwardly.

[0190] In some embodiments of the present application, the air purification device 1 is combined with Figures 6-8 As shown, the second hood half 923 is further provided with a mounting opening 803, and the purification element 11 is detachably assembled in the fresh air cavity V012 through the mounting opening 803. In this way, when the purification element 11 is damaged or saturated, the purification element 11 can be easily removed for maintenance or replacement.

[0191] In some embodiments of the present application, the air purification device 1 is combined with Figure 4 As shown, in the front-rear direction of the main body 1000, the mounting opening 803 is located on the front side of the main body 1000, and when the purification element 11 is removed, it can be free from interference from the fresh air inlet 801 and the exhaust air outlet 902. In this way, the purification element 11 can be easily removed. For example, the front side of the casing 1 is provided with an openable panel 15, and when the panel 15 is opened or turned upward, the mounting opening 803 is exposed, facilitating the removal of the purification element 11.

[0192] It is also not excluded that in some schemes, the mounting opening 803 is provided at the bottom of the main body 1000. Alternatively, the mounting opening 803 is provided at the top of the main body 1000.

[0193] Specifically, as shown in Figure 6 At least one of the first hood half 913 and the second hood half 923 is provided with a purification air inlet 804 for communicating with the indoor air.

[0194] The rotation of the fresh air fan 6 can cause the indoor air to enter the fresh air cavity V012 from the purification air inlet 804 to pass through the purification element 11 for purification, and can cause the indoor air entering the fresh air cavity V012 to blow through the purification element 11 and then enter the volute cavity V011 and from the fresh air outlet into the indoor air. In this way, the indoor air can enter the fresh air duct V01 from the purification air inlet 804, pass through the purification element 11, and then enter the indoor air from the fresh air outlet. In this way, when the indoor air is polluted, the indoor air can be circulated and purified. In this way, without introducing outdoor fresh air, the indoor air can be purified to improve the cleanliness. Since no outdoor fresh air is introduced, the indoor air is not suddenly blown into outdoor air without heat exchange, avoiding sudden changes in indoor temperature that cause discomfort.

[0195] In some embodiments of the present application, the purification air inlet 804 can communicate with the heat exchange air inlet 101, and no connecting pipe is needed between the purification air inlet 804 and the heat exchange air inlet 101, reducing the number of parts, reducing the occupied volume, and facilitating the layout.

[0196] In some embodiments of the present application, as shown in Figure 1 The wall-mounted air conditioner 10000 further comprises a panel 15, one end of the panel 15 being pivotally connected to the casing 1, for example, the upper end of the panel 15 being pivotally connected to the casing 1. The panel 15 is rotatable relative to the casing 1. When the panel 15 is rotated to an open state, the purifying member 11 is exposed, and the user can dismount the filter screen in the purifying member 11. When the panel 15 is rotated to a closed state, the purifying member 11 is shielded, and at this time, the panel 15 is an appearance member, and the appearance of the wall-mounted air conditioner 10000 is neat.

[0197] In some embodiments of the present application, as shown in Figure 1 The wall-mounted air conditioner 10000 further comprises a baffle 16, the left and right ends of the baffle 16 being pivotally connected to the casing 1. The baffle 16 is rotatable relative to the casing 1. When the baffle 16 is rotated to an open state, the heat exchange air outlet 102 is exposed, and air can be discharged from the heat exchange air outlet 102. When the baffle 16 is rotated to a closed state, the heat exchange air outlet 102 is shielded, and the heat exchange air outlet 102 of the wall-mounted air conditioner 10000 is prevented from being exposed when the wall-mounted air conditioner 10000 is not working, so that sundries, flying insects and the like cannot enter the interior of the wall-mounted air conditioner 10000 through the heat exchange air outlet 102.

[0198] Other components of the wall-mounted air conditioner 1000 according to the embodiments of the present application, for example, a controller and the like, are known to those skilled in the art, and their structures and principles will not be described in detail herein.
