[0041] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] Next, with reference to the drawings, a wall-mounted air conditioner 10000 according to an embodiment of the present application is described.

[0043] Referring to Figures 1-11 As shown, the wall-mounted air conditioner 10000 according to the embodiment of the present application comprises a main body 1000, the main body 1000 comprises a casing 1, an accommodating cavity V1 is formed inside the casing 1, and a heat exchange air inlet 101 and a heat exchange air outlet 102 are formed on the casing 1. The casing 1 can play a protective role and constitute the overall appearance structure of the wall-mounted air conditioner 10000.

[0044] Generally, the casing 1 is a long strip-shaped casing, and the length direction of the casing 1 is arranged along the horizontal direction, i.e., the casing 1 is arranged along the horizontal direction on the wall. In actual products, in order to discharge condensed water, the casing 1 is arranged along the horizontal direction on the wall in some embodiments, and the casing 1 is arranged at a small angle with the horizontal plane.

[0045] With reference to Figure 3 and Figure 4 , the 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 communicated with the refrigerant, and is used for refrigerating or heating 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 generally arranged along the length direction of the casing 1.

[0046] 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.

[0047] With reference to Figures 3-5 , the main body 1000 further comprises a base 3 arranged in the accommodating cavity V1. The base 3 is a mounting and supporting 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, and the indoor air entering the casing 1 is guided in the flow direction through the volute tongue air duct, so that the indoor air flowing through the indoor heat exchanger 2 is subjected to small resistance.

[0048] With reference to Figures 4-5 , the wall-mounted air conditioner 10000 further comprises a heat exchange fan 41 arranged in the volute tongue air duct. When the heat exchange fan 41 rotates, the air can be heat-exchanged between the inside of the air conditioner and the indoor space.

[0049] 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 casing 1, the driven air flow can flow through the entire indoor heat exchanger 2, which ensures the balance of heat exchange efficiency of each position of the indoor heat exchanger 2.

[0050] By arranging the heat exchange air outlet 102 and the heat exchange air inlet 101 in the casing 1, the indoor air can be sucked into the casing 1 from the heat exchange air inlet 101 when the heat exchange fan 41 operates, and 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.

[0051] Thus, the indoor environment temperature can be adjusted, the indoor heat exchanger 2 can serve as an evaporator to provide a cooling air flow to the indoor space through the heat exchange air outlet 102, or the indoor heat exchanger 2 can serve as a condenser to provide a heating air flow to the indoor space through the heat exchange air outlet 102.

[0052] 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.

[0053] For example, the height direction of the main body 1000 is the up-down direction.

[0054] It can be understood that 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 not easily blocked by the roof or the ground, so that the heat exchange air has small resistance consumption 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.

[0055] Referring to Figure 1 and Figure 2 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air inlet 101 can take in air from above, so that air is not taken in from the heat exchange air outlet 102, and the heat exchange air blown out from the heat exchange air outlet 102 is not directly sucked into the heat exchange air inlet 101, reducing the heat exchange air idling without participating in the indoor heat exchange process.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In some 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 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.

[0060] With reference to Figures 4-6 , the 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. 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.

[0061] In some embodiments, the wall-mounted air conditioner 10000 can comprise a motor support, which can be fixed on the base 3 and used to fix the common motor 42, so that the common motor 42 can be firmly installed on the main body 1000.

[0062] It can be understood that the wall-mounted air conditioner 10000 is generally in a long strip shape, the length direction of the heat exchange fan 41 is the same as the length direction of the main body 1000, and both are the left-right direction shown in FIG. 1. Figures 1-3

[0063] With reference to Figures 5-6 , the wall-mounted air conditioner 10000 further comprises a fresh air fan 6, which is an axial-inlet and radial-outlet centrifugal fan and 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.

[0064] With reference to Figures 5-6 , the wall-mounted air conditioner 10000 further comprises an exhaust fan 7, which is an axial-inlet and radial-outlet centrifugal fan.

[0065] The common motor 42 can drive the heat exchange fan 41, the fresh air fan 6 and the exhaust fan 7 to rotate synchronously in the working state.

[0066] The centrifugal fan itself has the characteristics of compact structure, large air volume and low noise, and the fan noise decreases significantly when the rotating speed decreases, so the fresh air fan 6 and the exhaust fan 7 can meet the demand of large air volume by selecting a centrifugal fan with a smaller size. 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 vibration and noise of the wall-mounted air conditioner 10000 as a whole.​

[0067] 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.

[0068] In some embodiments, 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.

[0069] 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.

[0070] 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.

[0071] In some embodiments, the common motor 42 can be an external rotor motor or an internal rotor motor.

[0072] Referring to Figures 7-9 , the wall-mounted air conditioner 10000 further includes a volute assembly, the volute assembly forms a fresh air cavity V01 and an exhaust air cavity V02, and the volute assembly forms a fresh air inlet, a fresh air outlet, an exhaust air inlet 901, and an exhaust air outlet (i.e., an upper air outlet 902 and a lower air outlet 903 described below). The fresh air inlet and the fresh air outlet both communicate with the fresh air cavity V01, and the exhaust air inlet 901 and the exhaust air outlet both communicate with the exhaust air cavity V02.

[0073] The fresh air fan 6 is arranged in the fresh air cavity V01. When the fresh air fan 6 rotates, outdoor air can enter the fresh air cavity V01 from the fresh air inlet, and the outdoor air in the fresh air cavity V01 can enter the indoor environment from the fresh air outlet. The fresh air fan 6 is used to drive air flow to be sucked from the fresh air inlet and discharged to the indoor environment from the fresh air outlet. The operation of the fresh air fan 6 provides power for the flow of fresh air.

[0074] Therefore, by arranging the fresh air cavity 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.

[0075] In some embodiments, the number of fresh air outlets can be one.

[0076] In some embodiments, the number of fresh air outlets can be multiple, for example, two, three, four or more. By arranging multiple fresh air outlets, the air outlet volume can be increased.

[0077] In some embodiments, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in the same direction.

[0078] In some embodiments, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in different directions.

[0079] The exhaust fan 7 is arranged in the exhaust cavity V02. When the exhaust fan 7 rotates, indoor air can enter the exhaust cavity V02 from the exhaust inlet 901, and the indoor air in the exhaust cavity V02 can be discharged to the outdoor environment from the exhaust outlet. The exhaust fan 7 is used to drive air flow to be sucked from the exhaust inlet 901 and discharged to the outdoor environment. The operation of the exhaust fan 7 provides power for the flow of dirty air.

[0080] Therefore, by arranging the exhaust cavity 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 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.

[0081] The fresh air fan 6, the exhaust fan 7 and the volute assembly constitute a bidirectional air exchange assembly, and the bidirectional air exchange assembly is arranged in the main body 1000. The bidirectional air exchange assembly can provide fresh air for the indoor environment and can discharge indoor air to the outdoor environment.

[0082] It should be noted that in the wall-mounted air conditioner 10000, the operation mode of the bidirectional air exchange assembly can be set according to actual use requirements.

[0083] In some embodiments, the bidirectional ventilation assembly can simultaneously run the fresh air mode and the exhaust air mode, that is, the fresh air cavity V01 and the exhaust air cavity V02 can be opened at the same time, while the indoor dirty air flows to the outdoor space, the fresh air from the outdoor can also enter the indoor space, and the indoor space air flow can be improved by the in-out air flow driving combination, thereby improving the efficiency of the indoor space air flow, and meeting the user's demand in time when the user needs to exhaust or update the indoor air.

[0084] Moreover, since the indoor air is exhausted to the outdoor while the fresh outdoor air is supplemented to the indoor, the indoor air amount is sufficient, and the indoor air is more easily sucked. For example, if there is a stimulating gas (such as a gas released by a home decoration material), coal gas or other gas leakage in the indoor, the bidirectional ventilation assembly can be simultaneously run in the fresh air mode and the exhaust air mode to achieve rapid ventilation. 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 good purification effect.

[0085] Moreover, when the air is exchanged, the indoor temperature is not changed too rapidly to cause discomfort of the indoor personnel due to the rapid temperature rise or drop. Moreover, the position of the main body 1000 is relatively high, and the ventilation position will not cause discomfort due to being too close to the personnel.

[0086] In some embodiments, the bidirectional ventilation assembly can run the fresh air mode and the exhaust air mode by means of a valve, that is, when the bidirectional ventilation assembly is started in the fresh air mode, the exhaust air mode is stopped, at this time, only the fresh air cavity V01 is ventilated, and the exhaust air cavity V02 is not ventilated. Or when the bidirectional ventilation assembly is started in the exhaust air mode, the fresh air mode is stopped, at this time, the fresh air cavity V01 is not ventilated, and the exhaust air cavity V02 is ventilated.

[0087] 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 to the indoor, and the cold energy generated by the wall-mounted air conditioner 10000 can still remain in the indoor, and the cold energy loss is small. The indoor air is exhausted to the outdoor through the exhaust air cavity V02, and by setting the exhaust air volume to be less than the fresh air volume, the cold energy loss can be reduced.

[0088] The bidirectional ventilation assembly is arranged at one end in the length direction of the heat exchange fan 41, and compared with the main body 1000 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, so that the main body 1000 is light and thin, and the wall-mounted air conditioner 10000 will not affect the indoor space layout due to being too conspicuous when being hung on the wall, and the wall-mounted air conditioner 10000 will not be difficult to fix due to being too heavy, thereby reducing the risk of falling from the wall.

[0089] In some embodiments, the bidirectional ventilation assembly can simultaneously run the fresh air mode and the exhaust air mode, that is, the fresh air cavity V01 and the exhaust air cavity V02 can be opened at the same time, while the indoor dirty air flows to the outdoor space, the fresh air from the outdoor can also enter the indoor space, and the indoor space air flow can be improved by the in-out air flow driving combination, thereby improving the efficiency of the indoor space air flow, and meeting the user's demand in time when the user needs to exhaust or update the indoor air. Figures 7-9As shown, the upper portion of the exhaust cavity V02 is provided with an upper air outlet 902, the volute assembly includes an exhaust duct 8 located at one side of the exhaust cavity V02 along the axial direction of the exhaust fan 7, the exhaust duct 8 extends in the up-down direction, the exhaust duct 8 is formed with an exhaust passage 84, the upper end of the exhaust passage 84 is communicated with the upper air outlet 902 and the lower end is formed with an air outlet opening, the air outlet opening is communicated with the outdoor, and the air outlet opening is used for discharging indoor air in the exhaust cavity V02 from the lower portion of the main body 1000 to the outdoor.

[0090] The side wall of the exhaust cavity V02 includes a first portion 904, which at least partially surrounds the exhaust fan 7. In a cross section perpendicular to the axis of the exhaust fan 7, the trajectory of the first portion 904 is formed as an involute relative to the exhaust fan 7, the distance between the first end of the first portion 904 and the exhaust fan 7 is smaller than the distance between the second end of the first portion 904 and the exhaust fan 7, and the first end of the first portion 904 is connected to the upper air outlet 902. The first end of the first portion 904 is used to partially tighten the distance between the side wall of the exhaust cavity V02 and the exhaust fan 7, so as to guide the indoor air flowing into the exhaust cavity V02 to the upper air outlet 902, and the airflow flowing into the upper air outlet 902 can flow into the exhaust passage 84 to flow along the exhaust passage 84, and then be discharged to the outdoor from the air outlet opening.

[0091] Through the above arrangement, the exhaust cavity V02 can discharge air to the outdoor through the exhaust duct 8, so that the exhaust air outlet of the exhaust cavity V02 can be flexibly arranged, and the exhaust duct 8 is arranged to be staggered with the exhaust cavity in the length direction of the main body 1000, which does not affect the size of the exhaust cavity V02 in the thickness direction of the main body 1000, and the space layout of the exhaust cavity V02 in the thickness direction of the main body 1000 can be maximized, so that the exhaust cavity V02 has a larger size, which is beneficial to increase the size of the exhaust fan 7, so as to improve the exhaust efficiency of the exhaust fan 7.

[0092] According to the wall-mounted air conditioner 10000 of the embodiment of the present application, the exhaust cavity V02 can discharge air to the outdoor through the exhaust duct 8, so that the exhaust air outlet of the exhaust cavity V02 can be flexibly arranged, so as to maximize the space layout of the exhaust cavity V02 in the thickness direction of the main body 1000, which is beneficial to increase the size of the exhaust fan 7, thereby improving the exhaust efficiency of the exhaust fan 7.

[0093] In some embodiments of the present application, as Figure 8As shown, the second end of the first portion 904 can also be connected to the upper air outlet 902. Specifically, when the indoor air flows into the exhaust cavity V02 from the exhaust air inlet 901, the indoor air can flow along the first portion 904 to flow into the exhaust air passage 84 from the upper air outlet 902, and then the indoor air can flow along the exhaust air passage 84 to flow out from the air outlet to the outdoor. In this way, the structure of the volute assembly can be simplified, thereby facilitating the processing difficulty of the wall-mounted air conditioner 10000.

[0094] In some embodiments of the present application, the lower part of the exhaust cavity V02 is provided with a lower air outlet 903, the second end of the first portion 904 is connected to the lower air outlet 903, the side wall of the exhaust cavity V02 includes a second portion 905, in a cross section perpendicular to the axis of the exhaust fan 7, the cross-sectional trajectory of the second portion 905 is formed as an involute relative to the exhaust fan 7, the distance between the first end of the second portion 905 and the exhaust fan 7 is less than the distance between the second end of the second portion 905 and the exhaust fan 7, the first end of the second portion 905 is connected to the lower air outlet 903, and the second end of the second portion 905 is connected to the upper air outlet 902.

[0095] For example, referring to Figures 10-11 As shown, the lower part of the exhaust cavity V02 is provided with a lower air outlet 903, the lower air outlet 903 is open downwardly, and the lower air outlet 903 is used for directly discharging the indoor air in the exhaust cavity V02 from the lower part of the main body 1000 to the outdoor. The first portion 904 is located between the upper air outlet 902 and the lower air outlet 903, the first end of the first portion 904 is connected to the upper air outlet 902, and the second end of the first portion 904 is connected to the lower air outlet 903.

[0096] The side wall of the exhaust cavity V02 includes a second portion 905, the second portion 905 is located between the upper air outlet 902 and the lower air outlet 903, in a cross section perpendicular to the axis of the exhaust fan 7, the cross-sectional trajectory of the second portion 905 is formed as an involute relative to the exhaust fan 7, the distance between the first end of the second portion 905 and the exhaust fan 7 is less than the distance between the second end of the second portion 905 and the exhaust fan 7, the first end of the second portion 905 is connected to the lower air outlet 903, and the second end of the second portion 905 is connected to the upper air outlet 902.

[0097] Specifically, when the exhaust fan 7 starts to work, the indoor air can enter the exhaust cavity V02 from the exhaust air inlet 901, and the indoor air flowing into the exhaust cavity V02 is divided into two parts, one part of the airflow can flow from the exhaust fan 7 to the first portion 904, and the airflow flows along the first portion 904 to the lower air outlet 903 to flow to the outdoor through the lower air outlet 903; the other part of the airflow can flow from the exhaust fan 7 to the second portion 905, and the airflow flows along the second portion 905 to the upper air outlet 902 to flow to the outdoor through the exhaust air passage 84.

[0098] Through the above arrangement, the outdoor exhaust can be achieved through the lower air outlet 903 and the exhaust channel 84 at the same time, which is beneficial to improve the exhaust efficiency of the exhaust fan 7 and improve the practicability of the wall-mounted air conditioner 10000.

[0099] In some embodiments of the present application, as shown in Figure 11 As shown in the cross section perpendicular to the axis of the exhaust fan 7, the first end of the first part 904 and the center of the exhaust fan 7 can be connected as a first line, and the first end of the second part 905 and the center of the exhaust fan 7 can be connected as a second line. The included angle between the first line and the second line opposite the lower air outlet 903 is α1, and the included angle between the second line and the first line opposite the upper air outlet 902 is α2, which satisfies: α2≥α1. That is, the part corresponding to the upper air outlet 902 of the exhaust fan 7 is greater than or equal to the part corresponding to the lower air outlet 903 of the exhaust fan 7, so that the airflow flowing to the upper air outlet 902 is greater than or equal to the airflow flowing to the lower air outlet 903.

[0100] Through the above arrangement, the size of the lower air outlet 903 in the thickness direction of the main body 1000 can be reduced, so as to maximize the use of the space layout of the main body 1000 in the thickness direction of the exhaust cavity V02, which is beneficial to increase the size of the exhaust fan 7, thereby improving the exhaust efficiency of the exhaust fan 7.

[0101] In some embodiments of the present application, α1≥120°, α1≤180°, α2≥180°, α2≤240°. That is, the included angle α1 between the first line and the second line opposite the lower air outlet 903 can be greater than or equal to 120° and less than or equal to 180°, and the included angle α2 between the second line and the first line opposite the upper air outlet 902 can be greater than or equal to 180° and less than or equal to 240°.

[0102] Exemplarily, the included angle α1 between the first line and the second line opposite the lower air outlet 903 can be 120°, and the included angle α2 between the second line and the first line opposite the upper air outlet 902 can be 240°; or the included angle α1 between the first line and the second line opposite the lower air outlet 903 can be 150°, and the included angle α2 between the second line and the first line opposite the upper air outlet 902 can be 210°; or the included angle α1 between the first line and the second line opposite the lower air outlet 903 can be 180°, and the included angle α2 between the second line and the first line opposite the upper air outlet 902 can be 180°. Through the above arrangement, the exhaust path can be optimized, which is beneficial to ensure the exhaust efficiency of the exhaust fan 7 and improve the design rationality of the wall-mounted air conditioner 10000.

[0103] In some embodiments of the present application, as shown in Figure 11 The upper air outlet 902 is configured as an upper air outlet channel, a first end of the upper air outlet 902 is close to the air exhaust cavity V02 and connected with the air exhaust cavity V02, and a second end of the upper air outlet 902 is away from the air exhaust cavity V02 and connected with the air exhaust channel 84. In the direction of extending from the first end to the second end of the upper air outlet 902, the cross-sectional area of the upper air outlet 902 can be gradually reduced.

[0104] It can be understood that when the air flow flows from the first end to the second end of the upper air outlet 902, the cross-sectional area of the upper air outlet 902 is gradually reduced and the flow rate of the air flow is gradually increased, so that the flow speed of the air flow in the air exhaust channel 84 is faster, so that the air flow can be discharged to the outdoor more quickly, which is beneficial to improve the air exhaust efficiency of the air exhaust fan 7.

[0105] In some embodiments of the present application, as shown in Figure 11 In the cross section perpendicular to the axis of the air exhaust fan 7, and in the direction of extending from the first end to the second end of the upper air outlet 902, the width of the upper air outlet 902 is gradually reduced, so that the cross-sectional area of the upper air outlet 902 is gradually reduced. Through the above setting, the structure of the upper air outlet 902 can be simplified, which is beneficial to reduce the processing difficulty of the volute assembly.

[0106] In some embodiments of the present application, as shown in Figure 11 The lower air outlet 903 can be configured as a lower air outlet channel, a first end of the lower air outlet 903 is close to the air exhaust cavity V02 and connected with the air exhaust cavity V02, and a second end of the lower air outlet 903 is away from the air exhaust cavity V02 and connected with the outdoor. In the direction of extending from the first end to the second end of the lower air outlet 903, the cross-sectional area of the lower air outlet 903 is gradually increased. In this way, when the indoor air flows from the first end to the second end of the lower air outlet 903, the air pressure of the indoor air will gradually decrease, so that a pressure difference can be formed between the first end and the second end of the lower air outlet 903. Therefore, the indoor air in the lower air outlet 903 can be more easily discharged to the outdoor, and the air exhaust efficiency of the lower air outlet 903 is improved.

[0107] In some embodiments of the present application, as shown in Figure 11 In the cross section perpendicular to the axis of the air exhaust fan 7, and in the direction of extending from the first end to the second end of the lower air outlet 903, the width of the lower air outlet 903 is gradually increased, so that the cross-sectional area of the lower air outlet 903 is gradually increased. Through the above setting, the thickness space of the main body 1000 can be fully utilized, which is beneficial to realize the miniaturization design of the wall-mounted air conditioner 10000.

[0108] In some embodiments of the present application, as shown in Figures 9-10As shown, the exhaust pipe 8 can be located on the side of the exhaust cavity V02 away from the fresh air cavity V01. In this way, the fresh air cavity V01 and the exhaust cavity V02 can be arranged adjacent to each other, and the space in the accommodating cavity V1 can be fully utilized, thereby facilitating reduction of the length dimension of the main body 1000.

[0109] In some embodiments of the present application, as shown in Figures 8-10 As shown, the exhaust pipe 8 includes a connecting section 81 and an extension section 82. The extension section 82 is located on the side of the exhaust cavity V02 away from the fresh air cavity V01, and extends in the up-down direction and has an air outlet opening at the lower end. The connecting section 81 is configured in an arc shape, and is used to connect the upper end of the extension section 82 and the upper air outlet 902, so that the airflow in the upper air outlet 902 can flow smoothly into the extension section 82 through the connecting section 81. In this way, the flow stability of the airflow during the exhaust process can be improved, thereby facilitating improvement of the exhaust efficiency.

[0110] In some embodiments, as shown in Figures 5-6 The exhaust fan 7 is located between the fresh air fan 6 and the heat exchange fan 41. In other words, the exhaust fan 7 is closer to the heat exchange fan 41 than the fresh air fan 6. When the wall-mounted air conditioner 10000 is in cooling or heating, the heat exchange fan 41 is operated to drive the indoor air entering the casing 1 from the heat exchange air inlet 101 to flow through the indoor heat exchanger 2. The exhaust fan 7 is close to the heat exchange fan 41, the air inlet end of the exhaust fan 7 is close to the air inlet end of the heat exchange fan 41, and the exhaust fan 7 can suck air from the air inlet end of the heat exchange fan 41, that is, the exhaust fan 7 can suck the indoor air entering the casing 1 from the heat exchange air inlet 101 to the exhaust fan 7 when the exhaust fan 7 rotates, thereby not needing to additionally open a hole in the casing 1 to separately introduce air to the exhaust fan 7, thereby reducing the number of openings in the casing 1, simplifying the machining and manufacturing process of the casing 1, and increasing the aesthetic degree. In addition, the heat exchange air inlet 101 is generally large, so the amount of indoor air sucked into the casing 1 through the heat exchange air inlet 101 is large, and the air volume reaching the exhaust fan 7 is also large, thereby accelerating the exhaust efficiency.

[0111] In addition, in some embodiments, the fresh air fan 6 is arranged on the side of the exhaust fan 7 away from the indoor heat exchanger 2. When there is condensate water on one side of the indoor heat exchanger 2, the condensate water is not easy to reach the fresh air fan 6, thereby reducing the risk of water accumulation and bacterial growth at the fresh air fan 6.

[0112] In some embodiments of the present application, as shown in Figures 7-11 As shown, the volute assembly includes a common volute 12 and an exhaust volute 9. The common volute 12 defines a part of the fresh air cavity V01. The exhaust volute 9 is located on the side of the common volute 12 facing the common motor 42, and the exhaust volute 9 is detachably connected to the common volute 12. The exhaust volute 9 and the common volute 12 together define the exhaust cavity V02.

[0113] In some embodiments of this utility model, the exhaust volute 9 encloses the exhaust air inlet 901, and the exhaust volute 9 and the common volute 12 enclose the exhaust air outlet. This simplifies the structure of the volute assembly and reduces the molding difficulty of the volute assembly.

[0114] In some embodiments, such as Figure 4 and Figure 7 As shown, the exhaust air inlet 901 is axially aligned with the length of the heat exchange fan 41. This means the exhaust air inlet 901 is directly opposite the axial intake end of the exhaust fan 7, minimizing air resistance at the exhaust air inlet 901 and ensuring sufficient exhaust airflow. When exhaust airflow is readily available, a smaller exhaust fan 7 can be selected, further reducing the size of the bidirectional ventilation assembly.

[0115] The exhaust air inlet 901 is axially oriented towards the indoor heat exchanger 2, that is, the air inlet area of ​​the exhaust air inlet 901 is oriented towards the indoor heat exchanger 2. In this way, the exhaust air inlet 901 is close to the heat exchange air inlet 101, and the air volume at the heat exchange air inlet 101 is large. A part of the air entering the casing 1 from the heat exchange air inlet 101 can enter the exhaust cavity V02 through the exhaust air inlet 901, so that the air volume at the exhaust air inlet 901 is sufficient.

[0116] The exhaust fan 7 and the fresh air fan 6 are located on the same side of the heat exchange fan 41. The exhaust fan 7 is disposed within the exhaust cavity V02 formed by the exhaust volute 9, and the fresh air fan 6 is disposed within the fresh air cavity V01 formed by the common volute 12. The volute sidewalls of adjacent positions of the exhaust fan 7 and the fresh air fan 6 can simultaneously serve as the volute sidewalls of both the exhaust fan 7 and the fresh air fan 6. For example, the plate along the vertical direction of the common volute 12 and the exhaust volute 9 can serve as the shared volute sidewall of the exhaust cavity V02 and the fresh air cavity V01, thus saving one component and improving overall integrity.

[0117] In some embodiments of this utility model, the exhaust pipe 8 can be connected to the exhaust volute 9. This ensures the stability of the connection between the exhaust cavity V02 and the exhaust channel 84, improves the stability of the exhaust process, and enhances the reliability of the wall-mounted air conditioner 10000.

[0118] In some embodiments of this utility model, such as Figure 7 As shown, the exhaust pipe 8 and the exhaust volute 9 can be integrally formed. This improves the sealing performance of the exhaust channel 84 and simplifies the assembly of the volute assembly, thus enhancing its practicality.

[0119] In some embodiments of this utility model, such as Figure 7As shown, the exhaust pipe 8 can be provided with a fixing portion 83, which is used to be connected with the base 3. Exemplarily, the fixing portion 83 can be provided with a fixing hole, and a fixing member penetrates through the fixing hole and is connected with the base 3. In this way, the mounting stability of the exhaust volute 9 can be improved, and the structural stability of the whole volute assembly can be improved.
