Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner. BACKGROUND

[0002] In order to reduce the indoor space occupied by the wall-mounted air conditioner and meet the user's requirement for the indoor soft decoration, some users choose to install the wall-mounted air conditioner on the top of a stand. An air inlet and an air outlet are formed on the front panel of the wall-mounted air conditioner, air is introduced into the accommodating cavity inside the air conditioner through the air inlet, and air is discharged to the indoor through the air outlet. However, when air is introduced into the accommodating cavity through the air inlet, the air flow impacts the volute tongue in the accommodating cavity, which causes the volute tongue to easily produce abnormal noise. This phenomenon is particularly obvious when the air conditioner is running at a high gear. In addition, air flow short circuit phenomenon easily occurs at the air inlet and the air outlet. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve one of the above technical problems in the prior art to some extent. To this end, the present application provides a wall-mounted air conditioner, which can improve the volute tongue noise problem when air is introduced into the air conditioner and can improve or even avoid the air flow short circuit problem at the air inlet and the air outlet.

[0004] The wall-mounted air conditioner according to the embodiments of the present application comprises a shell, and the shell has an accommodating cavity. The shell can protect the components (such as a heat exchanger, a heat exchange fan, etc.) in the accommodating cavity, thereby reducing the damage probability of the components in the accommodating cavity.

[0005] The wall-mounted air conditioner further comprises a front panel arranged on the front side of the shell. For example, when the wall-mounted air conditioner is hung on a wall, the front panel is the panel closest to the user and is also an important appearance surface of the wall-mounted air conditioner.

[0006] The wall-mounted air conditioner further comprises a heat exchanger arranged in the accommodating cavity. The heat exchanger is configured to exchange heat between indoor air and refrigerant transmitted in the heat exchanger.

[0007] The wall-mounted air conditioner further comprises a heat exchange fan arranged in the accommodating cavity. The heat exchange fan is rotatable, and the heat exchange fan is configured to suck indoor air into the wall-mounted air conditioner and send the indoor air exchanged with the heat exchanger to the indoor, and the heat exchange fan provides power for the flow of the indoor air.

[0008] The wall-mounted air conditioner further comprises a base arranged in the accommodating cavity, and the base comprises a volute tongue, a volute tongue air duct is formed in the volute tongue, and the heat exchange fan is rotatably arranged in the volute tongue air duct. The heat exchange fan can drive air flow through the volute tongue air duct when the heat exchange fan rotates.

[0009] The front panel is provided with an air inlet opening which communicates the accommodating cavity with the external environment for introducing air from the external environment into the accommodating cavity, and is provided with an air outlet opening which communicates the accommodating cavity with the external environment for discharging air in the accommodating cavity to the external environment, the air inlet opening and the air outlet opening are spaced apart in the height direction of the wall-mounted air conditioner, the heat exchanger is located between the air inlet opening and the heat exchange fan, the air inlet end of the volute tongue air duct faces the air inlet opening, and the air outlet end of the volute tongue air duct faces the air outlet opening. When the heat exchange fan rotates, indoor air can be sucked into the accommodating cavity from the air inlet opening, further sucked into the volute tongue air duct, and then blown into the room (i.e. indoor) through the air outlet opening, realizing the circulation of indoor air in the room (i.e. indoor) and the air conditioner.

[0010] The height of the front panel is H0, the height of the air inlet opening is h1, and the height of the air outlet opening is h2, and H0, h1 and h2 satisfy H0>0.5(h1+h2) and H0<(h1+h2). The height of the front panel is moderate, which can effectively separate the air inlet opening and the air outlet opening, the air inlet flow of the air inlet opening and the air outlet flow of the air outlet opening are far away from each other in the external environment, and they are not easy to cross and interfere with each other, and air flow short circuit phenomenon is not easy to occur at the air inlet opening and the air outlet opening, which does not affect the heat exchange effect. At the same time, the height of the air inlet opening is smaller than that of the conventional front panel with a smaller height, the gas flow from the air inlet opening to the heat exchanger is reduced, so that the flow impacting the volute is reduced, and the large noise generated by the air flow impacting the volute is avoided. When the air conditioner blows air at a higher gear, this noise reduction effect is particularly obvious. Moreover, the total height of the air inlet opening and the air outlet opening is not too small, and the air inlet amount and the air outlet amount are still sufficient, so as to ensure that the heat exchange efficiency of the wall-mounted air conditioner is high.

[0011] According to the wall-mounted air conditioner of the embodiments of the present application, by spacing the air inlet opening and the air outlet opening in the height direction of the wall-mounted air conditioner, the air flow short circuit problem at the air inlet opening and the air outlet opening can be improved or even avoided, thereby effectively improving the heat exchange effect in the room, by setting H0>0.5(h1+h2) and H0<(h1+h2), the gas flow from the air inlet opening to the heat exchanger is reduced, which is beneficial to reduce the air inlet noise generated by the air flow impacting the volute, and the air inlet flow of the air inlet opening and the air outlet flow of the air outlet opening are far away from each other in the external environment, and they are not easy to cross and interfere with each other, and air flow short circuit phenomenon is not easy to occur at the air inlet opening and the air outlet opening, which does not affect the heat exchange effect.

[0013] According to some embodiments of the present application, the heat exchanger is a two-fold heat exchanger or a three-fold heat exchanger, each fold structure of the heat exchanger is a plate structure, and the air inlet is located opposite to one of the fold structures. The presence of the front panel reduces the air flow from the air inlet to the fold heat exchanger located opposite to the air inlet, and abnormal noise is prone to occur when the air flow impacts the volute tongue. When the air flow is reduced, the abnormal noise at the volute tongue of the base can be reduced. The front panel can improve the sound quality performance of the air conditioner during air supply. In particular, when the air conditioner works at a higher gear, the noise reduction effect is more obvious.

[0014] According to some embodiments of the present application, the wall-mounted air conditioner further includes a deflector plate, the deflector plate is installed on the shell, and the deflector plate is rotatably arranged at the air outlet to adjust the air outlet direction at the air outlet. Thus, the user's adjustment demand for different air outlet directions can be met. For example, the air outlet direction at the air outlet can be adjusted to directly blow the user; the air outlet direction at the air outlet can also be adjusted to blow upward when the wall-mounted air conditioner cools, so that the cold air blown upward can sink from top to bottom due to its weight, thereby bringing the user a showering wind experience; the air outlet direction at the air outlet can also be adjusted to blow downward when the wall-mounted air conditioner heats, so that the hot air blown downward can rise from bottom to top due to its lightness, thereby passing through the user.

[0015] According to some embodiments of the present application, the deflector plate includes a first deflector plate and a second deflector plate, the first deflector plate is located above the second deflector plate in the height direction of the wall-mounted air conditioner, the first deflector plate is rotatably connected to the shell, the second deflector plate is rotatably connected to the shell, and the first deflector plate and the second deflector plate can rotate to a closed position and an open position. In the closed position, the first deflector plate and the second deflector plate are spliced or at least partially overlapped to block the air outlet. In the open position, the first deflector plate and the second deflector plate are separated to open the air outlet. By arranging the first deflector plate and the second deflector plate, the air outlet can be opened or closed, and the opening size of the air outlet can be adjusted.

[0016] According to some embodiments of the present application, the first air deflector has a rotation angle range of 0°-60°. When the rotation angle of the first air deflector is 0°, the first air deflector is in a closed position; when the rotation angle of the first air deflector is greater than 0° and not greater than 60°, the first air deflector is in an open position, and the first air deflector can guide the airflow forward and downward when it is open, effectively reducing the airflow short circuit at the air outlet and the air inlet.

[0017] According to some embodiments of the present application, the second air deflector has a rotation angle range of 0°-120°. When the rotation angle of the second air deflector is 0°, the second air deflector is in a closed position; when the rotation angle of the second air deflector is greater than 0° and not greater than 120°, the second air deflector is in an open position, and the second air deflector can achieve wide-angle air supply in the room when it is open.

DETAILED DESCRIPTION

[0049] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0050] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] To reduce the space occupied by wall-mounted air conditioners and meet users' aesthetic requirements for interior decoration, some users choose to install wall-mounted air conditioners on top of cabinets. The front panel of the wall-mounted air conditioner has an air inlet and an air outlet. Air enters the internal cavity through the air inlet and exits into the room through the air outlet. However, when air enters the cavity through the air inlet, the airflow impacts the volute inside the cavity, causing abnormal noise. This phenomenon is particularly noticeable when the air conditioner is operating at higher settings, and airflow short-circuiting can easily occur between the air inlet and outlet.

[0052] To address the aforementioned issues, some embodiments of this application provide a wall-mounted air conditioner 10 that can improve the volute noise problem during air intake and improve or even avoid the airflow short-circuit problem at the air inlet 41 and the air outlet 42.

[0053] The following is combined with Figures 1-12 A detailed description of the wall-mounted air conditioner 10 according to an embodiment of this application.

[0054] Reference Figures 1-4 As shown, the wall-mounted air conditioner 10 according to an embodiment of this application includes a housing 1, and the housing 1 has a receiving cavity 13. The housing 1 can protect the components (such as the heat exchanger 2, heat exchange fan 3, etc. mentioned below) in the receiving cavity 13, reducing the probability of damage to the components in the receiving cavity 13.

[0055] Reference Figures 1-4 As shown, the wall-mounted air conditioner 10 also includes a front panel 4, which is located on the front side of the casing 1. For example, when the wall-mounted air conditioner 10 is mounted on the wall, the front panel 4 is the panel closest to the user and is also an important appearance surface of the wall-mounted air conditioner 10.

[0056] Reference Figures 3-4 As shown, the wall-mounted air conditioner 10 also includes a heat exchanger 2, which is disposed within the housing cavity 13. The heat exchanger 2 is configured to exchange heat between indoor air and refrigerant transported within it.

[0057] In some embodiments, the heat exchanger 2 may include heat exchange fins to increase the contact area between indoor air and the refrigerant transported in the heat exchanger 2, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0058] With reference to Figures 3-4 As shown in the figure, the wall-mounted air conditioner 10 further comprises a heat exchange fan 3, which is arranged in the accommodating cavity 13. The heat exchange fan 3 is rotatable, and is configured to suck indoor air into the wall-mounted air conditioner 10 and send the indoor air after heat exchange with the heat exchanger 2 to the indoor environment, and provides power for the flow of the indoor air. Specifically, the rotation of the heat exchange fan 3 is driven by the first motor, and the wall-mounted air conditioner 10 further comprises a control device connected with the first motor driving the rotation of the heat exchange fan 3 through a data line to transmit communication information.

[0059] With reference to Figures 3-5 As shown in the figure, one side of the front panel 4 is provided with an air inlet 41, which is communicated with the accommodating cavity 13 and the external environment for introducing the air of the external environment into the accommodating cavity 13, and the other side of the front panel 4 is provided with an air outlet 42, which is communicated with the accommodating cavity 13 and the external environment for discharging the air in the accommodating cavity 13 to the external environment, and the air inlet 41 and the air outlet 42 are spaced apart in the height direction of the wall-mounted air conditioner 10, and the heat exchanger 2 is located between the air inlet 41 and the heat exchange fan 3. The heat exchange fan 3 provides power for the flow of the indoor air when rotating, and drives the indoor air to enter the accommodating cavity 13 from the air inlet 41, and the indoor air after entering the accommodating cavity 13 from the air inlet 41 exchanges heat with the heat exchanger 2, and the heat exchange fan 3 also drives the indoor air after heat exchange with the heat exchanger 2 to be sent to the indoor environment through the air outlet 42.

[0060] The air inlet 41 and the air outlet 42 are located on the two sides of the front panel 4, the air inlet flow of the air inlet 41 and the air outlet flow of the air outlet 42 are far away from each other in the external environment, and they are not easy to cross and interfere with each other, and the air inlet 41 and the air outlet 42 are not easy to cause air flow short circuit phenomenon, and do not affect the heat exchange effect.

[0061] When the wall-mounted air conditioner 10 cools, the temperature of the indoor air entering the accommodating cavity 13 from the air inlet 41 is higher than the temperature of the heat exchanger 2, and the heat of the indoor air is transferred to the heat exchanger 2, so that the indoor air is cooled, and this part of the air can reduce the indoor temperature after entering the indoor environment; when the wall-mounted air conditioner 10 heats, the temperature of the indoor air entering the accommodating cavity 13 from the air inlet 41 is lower than the temperature of the heat exchanger 2, and the indoor air absorbs heat from the heat exchanger 2, so that the indoor air is heated, and this part of the air can increase the indoor temperature after entering the indoor environment.

[0062] Specifically, when the wall-mounted air conditioner 10 is an indoor unit, the "external environment" referred to herein is the indoor environment. The heat exchange fan 3 drives the indoor air after heat exchange with the heat exchanger 2 in the accommodating cavity 13 to be sent to the indoor environment through the air outlet 42. The air outlet 42 and the air inlet 41 are different ports, so as to avoid interference between the air inlet and the air outlet.

[0063] By setting the air inlet 41 and the air outlet 42 apart in the height direction of the wall-mounted air conditioner 10, the air flow of the air inlet 41 and the air flow of the air outlet 42 are far apart in the height direction of the wall-mounted air conditioner 10 in the external environment, and the two air flows are not easy to cross and interfere with each other, so that the air flow short circuit problem at the air inlet 41 and the air outlet 42 can be improved or even avoided, thereby effectively improving the heat exchange effect in the room.

[0064] With reference to Figures 3-4 As shown in the figure, the wall-mounted air conditioner 10 further comprises a base 7, which is arranged in the accommodating cavity 13. The base 7 comprises a volute tongue, and a volute tongue air duct 71 is formed in the volute tongue. The heat exchange fan 3 is rotatably arranged in the volute tongue air duct 71. The air inlet end of the volute tongue air duct 71 faces the air inlet 41, and the air outlet end of the volute tongue air duct 71 faces the air outlet 42. When the heat exchange fan 3 rotates, indoor air can be sucked from the air inlet 41 into the accommodating cavity 13, further into the volute tongue air duct 71, and then blown back into the room through the air outlet 42, realizing the circulation of indoor air in the room (i.e. indoor) and the air conditioner.

[0065] Specifically, the heat exchange fan 3 can be arranged at the air inlet end of the volute tongue air duct 71, at the air outlet end of the volute tongue air duct 71, or at an intermediate position in the volute tongue air duct 71.

[0066] With reference to Figures 3-4 As shown in the figure, the volute tongue air duct 71 is provided with a guide vane 63. The guide vane 63 can be rotated to change the air flow speed in the volute tongue air duct 71. For example, when the guide vane 63 is rotated to be perpendicular to the air flow direction, the air flow speed in the volute tongue air duct 71 is small; when the guide vane 63 is rotated to be parallel to the air flow direction, the air flow speed in the volute tongue air duct 71 is large. The rotation of the guide vane 63 can be driven by the second motor.

[0067] In the related art, the air flow from the air inlet into the accommodating cavity can impact the volute and produce abnormal noise. In the present application, the presence of the front panel 4 reduces the air flow from the air inlet 41 to the heat exchanger 2, thereby reducing the flow impacting the volute and reducing the abnormal noise at the base 7. The setting of the front panel 4 can improve the sound quality performance of the air conditioner during air supply, especially when the air conditioner works at a higher gear, the noise reduction effect is more obvious.

[0068] With reference to Figures 3-5As shown, the height of the front panel 4 is H0, the height of the air inlet 41 is hi, and the height of the air outlet 42 is h2, and H0, hi, and h2 satisfy H0>0.5(h1+h2). In other words, the height of the front panel 4 is greater than half the sum of the heights of the air inlet 41 and the air outlet 42, so that the height of the front panel 4 is relatively large, and the phenomenon that the air flow at the air inlet 41 and the air outlet 42 is easily disturbed or short-circuited when the height of the front panel 4 is small is avoided. Moreover, the height of the front panel 4 is relatively large, so that the height of the air inlet 41 is relatively small, the air flow reaching the heat exchanger 2 from the air inlet 41 is reduced, and thus the flow rate of the air flow impacting the volute tongue is reduced, and the phenomenon that the air flow impacting the volute tongue produces relatively large noise is avoided.

[0069] H0, hi, and h2 also satisfy H0<(h1+h2). In other words, the height of the front panel 4 is less than the sum of the heights of the air inlet 41 and the air outlet 42, so that the sum of the air inlet 41 and the air outlet 42 is not too small, and the air inlet amount and the air outlet amount can still be relatively sufficient, so that the heat exchange efficiency of the wall-mounted air conditioner 10 is relatively high.

[0070] In some embodiments, H0, hi, and h2 satisfy 0.5(h1+h2)<H0<(h1+h2). Thus, the height of the front panel 4 is moderate, the air inlet 41 and the air outlet 42 can be effectively separated, the air inlet flow of the air inlet 41 and the air outlet flow of the air outlet 42 are far away from each other in the external environment, and the two do not easily cross and interfere with each other, and the air inlet 41 and the air outlet 42 do not easily have the phenomenon of air flow short circuit, and the heat exchange effect is not affected. At the same time, the height of the air inlet 41 is relatively small compared with the conventional front panel with a small height, the air flow reaching the heat exchanger 2 from the air inlet 41 is reduced, so that the flow rate of the air flow impacting the volute tongue is reduced, and the phenomenon that the air flow impacting the volute tongue produces relatively large noise is avoided. This noise reduction effect is particularly obvious when the air conditioner is blowing at a high gear. Moreover, the sum of the air inlet 41 and the air outlet 42 is not too small, and the air inlet amount and the air outlet amount can still be relatively sufficient, so that the heat exchange efficiency of the wall-mounted air conditioner 10 is relatively high.

[0071] For example, H0 can be 0.6(h1+h2), 0.6(h1+h2), 0.7(h1+h2), 0.8(h1+h2), 0.9(h1+h2), etc.

[0072] According to the wall-mounted air conditioner 10 of the embodiments of the present application, the air inlet 41 and the air outlet 42 are spaced apart in the height direction of the wall-mounted air conditioner 10, so that the air flow short circuit problem at the air inlet 41 and the air outlet 42 can be improved or even avoided, thereby effectively improving the heat exchange effect in the room. By setting H0>0.5(h1+h2), H0<(h1+h2), the air flow reaching the heat exchanger 2 from the air inlet 41 is reduced, which is beneficial to reducing the air inlet noise caused by the air flow impacting the volute tongue, and the air inlet flow at the air inlet 41 and the air outlet flow at the air outlet 42 are far away from each other in the external environment, and they are not easy to cross and interfere with each other, so that the air flow short circuit phenomenon does not easily occur at the air inlet 41 and the air outlet 42, and the heat exchange effect is not affected.

[0073] In some embodiments of the present application, referring to Figures 3-5 As shown in the figure, the air inlet 41 is located on the upper side of the front panel 4, and the air outlet 42 is located on the lower side of the front panel 4. The wall-mounted air conditioner 10 is usually arranged near the ceiling 303, so that the air outlet 42 is closer to the user, and the air blown out of the air outlet 42 can directly blow to the user.

[0074] Referring to Figures 3-4 As shown in the figure, the volute tongue includes a first volute tongue 72 and a second volute tongue 73, the first volute tongue 72 is located on the front side of the second volute tongue 73, and the volute tongue air duct 71 is formed between the first volute tongue 72 and the second volute tongue 73. In the height direction of the wall-mounted air conditioner 10, the lower end edge of the air inlet 41 is not lower than the upper end edge of the first volute tongue 72, and the lower end edge of the air inlet 41 is not lower than the upper end edge of the second volute tongue 73. That is, the air inlet 41 is located above the volute tongue, and the air inlet 41 and the volute tongue are staggered, so that the air flow entering the air inlet 41 directly impacts the volute tongue after flowing through the heat exchanger 2 can be avoided, specifically, the air flow entering the air inlet 41 directly impacts the first volute tongue 72 and the second volute tongue 73 after flowing through the heat exchanger 2 can be avoided, so that the air flow impacting the volute tongue produces a large noise can be avoided. This noise reduction effect is particularly obvious when the air conditioner is blowing at a higher gear.

[0075] In some embodiments, the upper end edge of the second volute tongue 73 is higher than the upper end edge of the first volute tongue 72, so that the upper end edge of the first volute tongue 72 is lower than the upper end edge of the second volute tongue 73, and the air flow entering the accommodation cavity 13 from the air inlet 41 is more easily to enter the volute tongue air duct 71.

[0076] In some embodiments of the present application, the heat exchanger 2 is a two-fold heat exchanger or a three-fold heat exchanger, each fold structure of the heat exchanger 2 is a plate structure, and the air inlet 41 is arranged opposite to one of the fold structures. The presence of the front panel 4 reduces the air flow from the air inlet 41 to the fold heat exchanger arranged opposite to the air inlet 41, and this part of the air flow impacting the volute tongue is prone to produce abnormal noise. When the air flow is reduced, the abnormal noise at the volute tongue of the base 7 can be reduced. The front panel 4 can improve the sound quality performance of the air conditioner during air supply, and the noise reduction effect is more obvious when the air conditioner works at a higher gear.

[0077] In Figures 3-4 the example, the heat exchanger 2 is a two-fold heat exchanger, specifically, the heat exchanger 2 includes a first fold heat exchanger 21 and a second fold heat exchanger 22. The presence of the front panel 4 reduces the air flow from the air inlet 41 to the first fold heat exchanger 21, and this part of the air flow impacting the volute tongue is prone to produce abnormal noise. When the air flow is reduced, the abnormal noise at the volute tongue of the base 7 can be reduced. The front panel 4 can improve the sound quality performance of the air conditioner during air supply, and the noise reduction effect is more obvious when the air conditioner works at a higher gear.

[0078] In some embodiments of the present application, referring to Figures 1-4 , the wall-mounted air conditioner 10 further includes an air guide plate 6. The air guide plate 6 is installed on the cabinet 1 and is rotatably arranged at the air outlet 42 to adjust the air outlet direction at the air outlet 42. Thus, the user's adjustment demand for different air outlet directions can be met. For example, the air outlet direction at the air outlet 42 can be adjusted to directly blow the user. When the wall-mounted air conditioner 10 is cooling, the air outlet direction at the air outlet 42 can be adjusted to blow air upward. The relatively cold air blown upward is relatively heavy and can sink from top to bottom, thus giving the user a showering wind experience. When the wall-mounted air conditioner 10 is heating, the air outlet direction at the air outlet 42 can be adjusted to blow air downward. The relatively hot air blown downward is relatively light and can rise from bottom to top, thus passing through the user.

[0079] In some embodiments of the present application, the number of air guide plates 6 is one. In this way, the number of air guide plates 6 is small, and the structure is simple, which is beneficial to saving cost.

[0080] In some embodiments of the present application, the number of air guide plates 6 is multiple. For example, referring to Figures 1-4 , the air guide plate 6 includes a first air guide plate 61 and a second air guide plate 62. In the height direction of the wall-mounted air conditioner 10, the first air guide plate 61 is located above the second air guide plate 62. The first air guide plate 61 and the second air guide plate 62 are rotatably connected with the cabinet 1. The first air guide plate 61 and the second air guide plate 62 can rotate to a closed position and an open position. In the closed position, as shown in Figure 3As shown, the first air deflector 61 and the second air deflector 62 are spliced or at least partially overlapped to block the air outlet 42. In the open position, as shown in Figure 4 As shown, the first air deflector 61 and the second air deflector 62 are separated to open the air outlet 42. By arranging the first air deflector 61 and the second air deflector 62, the air outlet 42 can be opened or closed, and the opening size of the air outlet 42 can be adjusted.

[0081] In some embodiments of the present application, the rotation angle range of the first air deflector 61 is 0°-60°. When the rotation angle of the first air deflector 61 is 0°, the first air deflector 61 is in the closed position. When the rotation angle of the first air deflector 61 is greater than 0°, the first air deflector 61 is in the open position. When the first air deflector 61 is open, it can guide the airflow forward and downward, which can effectively reduce the airflow short circuit at the air outlet 42 and the air inlet 41.

[0082] Referring to Figures 3-4 As shown, the angle between the first air deflector 61 and the vertical direction is α, and α≥0° and α≤60°. When α=0°, the first air deflector 61 is arranged along the vertical direction to partially block the air outlet 42. When 0°<α≤60°, the first air deflector 61 is inclined forward and downward relative to the vertical direction, so that the air outlet 42 is open, and the first air deflector 61 guides the airflow forward and downward, which is beneficial to reduce the airflow short circuit at the air outlet 42 and the air inlet 41. When α=60°, the first air deflector 61 is inclined at the maximum angle relative to the vertical direction.

[0083] For example, α can be 0°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, etc.

[0084] In some embodiments of the present application, the rotation angle range of the second air deflector 62 is 0°-120°. When the rotation angle of the second air deflector 62 is 0°, the second air deflector 62 is in the closed position. When the rotation angle of the second air deflector 62 is greater than 0°, the second air deflector 62 is in the open position. When the second air deflector 62 is open, it can achieve wide-angle air supply in the room.

[0085] Referring to Figures 3-4 As shown, the angle between the second air deflector 62 and the vertical direction is β, and β≥0° and β≤120°. When β=0°, the second air deflector 62 is arranged along the vertical direction to partially block the air outlet 42. When 0°<β≤120°, the second air deflector 62 is inclined relative to the vertical direction, so that the air outlet 42 is open. When β=120°, the second air deflector 62 is inclined at the maximum angle relative to the vertical direction.

[0086] For example, β can be 0°, 20°, 40°, 45°, 60°, 80°, 90°, 100°, 120°, etc.

[0087] When α = 60° and β = 120°, the effective air outlet area of the air outlet 42 is the largest.

[0088] The angle setting of the first air deflector 61 and the second air deflector 62 when opened can effectively reduce air flow short circuit and achieve wide-angle air supply in the room.

[0089] In some embodiments, the mounting shafts of the plurality of air deflectors 6 can be arranged in parallel, and the plurality of air deflectors 6 can swing synchronously or asynchronously. The swinging of each air deflector 6 can be manually operated or operated by a motor. In some embodiments not shown in the figure, the number of air deflectors 6 can also be three, four, five, six, etc.

[0090] In some embodiments of the present application, referring to FIG. 1, the air deflector 6 extends along the length direction of the wall-mounted air conditioner 10. In this way, when air is blown out through the gap on the side edge of the air deflector 6, a continuous air flow can be formed in the length direction of the wall-mounted air conditioner 10. Figures 1-2 In some embodiments of the present application, referring to FIG. 1, the wall-mounted air conditioner 10 further comprises an air inlet grille 5, the air inlet grille 5 is mounted to the front panel 4, the air inlet grille 5 is arranged at the air inlet 41, the air inlet grille 5 has a plurality of grille holes, the grille holes are in communication with the air inlet 41. The air inlet grille 5 can protect the air inlet 41 and shield a part of the air inlet 41, thereby preventing sundries, small animals, etc. from entering the accommodation cavity 13 through the air inlet 41. The arrangement of the grille holes enables the accommodation cavity 13 to be in communication with the external environment at the air inlet 41.

[0091] Figures 1-4 In some embodiments of the present application, the shape of the grille hole is arbitrary, for example, the grille hole can be a strip hole, a circular hole, a triangular hole, etc.

[0092] In some embodiments of the present application, the air inlet grille 5 comprises a grille strip, the grille strip is rotatable to adjust the air inlet direction at the air inlet 41, thereby meeting the adjustment demand of the user for different air inlet directions.

[0093] In some embodiments of the present application, the grille strip comprises a first grille strip and a second grille strip, the first grille strip extends along a first direction, the second grille strip extends along a second direction, and the first direction is different from the second direction. By rotating the first grille strip and the second grille strip, multi-directional adjustment of the air inlet direction can be achieved.

[0094] In some embodiments of the present application, the grille strip comprises a first grille strip and a second grille strip, the first grille strip extends along a first direction, the second grille strip extends along a second direction, and the first direction is different from the second direction. By rotating the first grille strip and the second grille strip, multi-directional adjustment of the air inlet direction can be achieved.

[0095] ​For example, the first direction is the height direction of the wall-mounted air conditioner 10, and the second direction is the width direction of the wall-mounted air conditioner 10. Of course, the first and second directions can also be other directions. For example, the first direction and the height direction of the wall-mounted air conditioner 10 have an acute angle, and the second direction and the width direction of the wall-mounted air conditioner 10 have an acute angle.

[0096] In some embodiments of this application, reference is made to Figures 1-2 , Figures 5-12 As shown, the wall-mounted air conditioner 10 also includes a baffle device 8, which is provided on at least one side of the casing 1 in the lateral direction. Specifically, the baffle device 8 is located on the side of the pipe extending outward from the casing 1. The baffle device 8 can completely cover the installation gap reserved on the side of the air conditioner, and the installation of the baffle device 8 facilitates the complete concealment of the air conditioning pipes.

[0097] exist Figure 6 , Figure 9 In the example, the pipeline extends from the left lateral side of the casing 1. Therefore, the baffle device 8 is only provided on the left lateral side of the casing 1. When installing the wall-mounted air conditioner 10, the air conditioner body (including the front panel 4, air inlet grille 5, air guide plate 6, casing 1 and internal components, excluding the baffle device 8) is placed on the right side in the reserved space above the cabinet 20. After installation, the baffle device 8 is fixed to the left side of the casing 1 with screws to hide the pipeline on the left side of the air conditioner.

[0098] In some embodiments not shown in the figure, the pipeline extends from the right side of the casing 1, therefore, the baffle device 8 is only provided on the right side of the casing 1. When installing the wall-mounted air conditioner 10, the air conditioner body is placed on the left side in the reserved space above the cabinet 20. After installation, the baffle device 8 is fixed to the right side of the casing 1 with screws to hide the pipeline on the right side of the air conditioner.

[0099] In some embodiments not shown in the figure, the pipelines extend from both the left and right sides of the casing 1. Therefore, baffle devices 8 are provided on both the left and right sides of the casing 1. When installing the wall-mounted air conditioner 10, the air conditioner body is placed in the reserved space above the cabinet 20. After installation, the left baffle device 8 is fixed to the left side of the casing 1 with screws, and the right baffle device 8 is fixed to the right side of the casing 1 with screws, thus concealing the pipelines on the left and right sides of the air conditioner.

[0100] In some embodiments not shown in the figure, the baffle device 8 is a single plate structure. The baffle device 8 is installed on the side of the housing 1 and in front of the air conditioning pipeline to block the air conditioning pipeline.

[0101] Reference Figures 7-10 As shown, the baffle device 8 includes a mounting base 81 for mounting to the housing 1. (Refer to...) Figures 6-10As shown, the baffle device 8 further comprises a baffle body 82, the baffle body 82 is installed on the mounting seat 81, the baffle body 82 can move relative to the mounting seat 81 in the length direction of the cabinet 1, and the rear side of the baffle body 82 can be used for wiring. In other words, the rear side of the baffle body 82 forms a wiring space V1, and the pipeline of the wall-mounted air conditioner 10 is arranged in the wiring space V1. By changing the moving position of the baffle body 82, the complete hiding of the pipeline can be realized. The telescopic design of the baffle body 82 can adapt to different sizes of reserved spaces, realize the complete invisible effect of the appearance of the air conditioner, and meet the user's demand for aesthetics.

[0102] In order to reduce the indoor space occupied by the wall-mounted air conditioner and meet the user's demand for the aesthetics of indoor soft decoration, the wall-mounted air conditioner 10 is installed on the top of the cabinet 20, and the cabinet 20 and the wall-mounted air conditioner 10 form a cabinet air conditioner assembly 100. The conventional wall-mounted air conditioner takes in air from the rear side and discharges air from the front side, so that sufficient space needs to be reserved between the four sides of the air conditioner (especially the top and bottom) and the inner wall of the cabinet or the wall, which is also a heavy dust accumulation area and increases the user's cleaning burden. The existence of these spaces also makes the air conditioner unable to realize the embedded effect. The wall-mounted air conditioner 10 of the present application reasonably utilizes the space on the top of the cabinet 20, embeds the air conditioner body on the top of the cabinet 20, and sets the air inlet 41 and the air outlet 42 on the front panel 4, so that the air conditioner does not need to reserve an air inlet space around the air conditioner, and the top and bottom of the air conditioner can be attached to the inner wall of the cabinet 20 or the wall, thereby facilitating the formation of an embedded air conditioner with invisible appearance and reducing dust accumulation and the user's cleaning burden.

[0103] The wall-mounted air conditioner 10 of the present application realizes front air intake and front air discharge, and only the front panel 4 is exposed, and the other surfaces can be hidden in the cabinet 20.

[0104] Referring to Figure 11 As shown, when the wall-mounted air conditioner 10 is installed on the top of the cabinet 20, the right side of the wall-mounted air conditioner 10 abuts against the right side wall 302, and the baffle body 82 extends to the left to abut against the left side wall 301, so that the baffle body 82 blocks the gap between the cabinet 1 and the left side wall 301. The telescopic design of the baffle body 82 can adapt to different sizes of spaces, so as to block the gap between the wall-mounted air conditioner 10 and the side wall (such as the left side wall 301), and realize the embedded development of the wall-mounted air conditioner 10.

[0105] In some embodiments of the present application, referring to Figure 11 As shown, the wall-mounted air conditioner 10 has a gap L3 between the top and the roof 303, and L3≥0.

[0106] For example, L3 = 0, thus, there is no gap above the wall-mounted air conditioner 10, and the embedded effect of the wall-mounted air conditioner 10 can be achieved.

[0107] For example, L3 > 0, thus, when the wall-mounted air conditioner 10 is installed on the top of the cabinet 20, the upper surface of the wall-mounted air conditioner 10 can be prevented from interfering with the roof 303.

[0108] Figure 11 As shown, the shell 1 of the wall-mounted air conditioner 10 is square in structure, which is convenient to directly place on the top of the cabinet 20, embedded in the area between the cabinet 20 and the roof 303, and easy to install without the need for punching holes, and the gap between the cabinet 20 and the roof 303 is fully utilized. Moreover, the scheme effectively avoids the reserved space around the conventional wall-mounted air conditioner, and greatly reduces the cleaning burden.

[0109] Referring to Figure 12 As shown, when the wall-mounted air conditioner 10 is installed inside the cabinet 20, the right side of the wall-mounted air conditioner 10 is attached to the right inner wall 202, and the baffle body 82 is extended to the left to be attached to the left inner wall 201, thus, the baffle body 82 blocks the gap between the shell 1 and the left inner wall 201. The telescopic design of the baffle body 82 can adapt to different sizes of space, so as to block the gap between the wall-mounted air conditioner 10 and the side wall (such as the left inner wall 201) of the cabinet, and realize the embedded development of the wall-mounted air conditioner 10.

[0110] In some embodiments of the present application, referring to Figure 12 As shown, there is a gap L4 between the top of the wall-mounted air conditioner 10 and the top inner wall 203 of the cabinet 20, L4 ≥ 0, and the bottom of the wall-mounted air conditioner 10 is placed on the partition plate 204 of the cabinet 20.

[0111] For example, L4 = 0, thus, there is no gap above the wall-mounted air conditioner 10, and the embedded effect of the wall-mounted air conditioner 10 can be achieved.

[0112] For example, L4 > 0, thus, when the wall-mounted air conditioner 10 is installed on the top of the cabinet 20, the upper surface of the wall-mounted air conditioner 10 can be prevented from interfering with the top inner wall 203.

[0113] Figure 12 As shown, the shell 1 of the wall-mounted air conditioner 10 is square in structure, which is convenient to directly place on the top of the cabinet 20, embedded in the area between the cabinet 20 and the roof 303, and easy to install without the need for punching holes, and the gap between the cabinet 20 and the roof 303 is fully utilized. Moreover, the scheme effectively avoids the reserved space around the conventional wall-mounted air conditioner, and greatly reduces the cleaning burden.

[0114] The wall-mounted air conditioner 10 of the present application solves the problems of unattractive appearance and difficult cleaning when the indoor wall-mounted air conditioner 10 is placed on the top of the cabinet 20. The air inlet 41 and the air outlet 42 are located on the same plane, and no ventilation gap is required at the top and bottom of the wall-mounted air conditioner 10. By providing the baffle device 8, the installation gap in the length direction of the wall-mounted air conditioner 10 can be filled.

[0115] In some embodiments of the present application, the wall-mounted air conditioner 10 further comprises a driving device provided on the mounting seat 81. The driving device is used to drive the baffle body 82 to move, and provides power for the movement of the baffle body 82. The driving device can be a motor, or a combination of a motor and a speed reducer.

[0116] Referring to Figures 7-10 , the wall-mounted air conditioner 10 further comprises a transmission mechanism 9 connected with the driving device and the baffle body 82. The transmission mechanism 9 is used to transmit the power of the driving device to the baffle body 82.

[0117] In some embodiments of the present application, referring to Figures 7-10 , the transmission mechanism 9 comprises a transmission gear 91 and a transmission rack 92. The transmission gear 91 is installed on the driving shaft of the driving device, and the transmission rack 92 is installed on the baffle body 82. The transmission rack 92 is in meshing transmission with the transmission gear 91. When the driving shaft rotates, it drives the transmission gear 91 to rotate, and when the transmission gear 91 rotates, it drives the transmission rack 92 to move. When the transmission rack 92 moves, it drives the baffle body 82 to move synchronously, thereby realizing the telescopic adjustment of the baffle body 82 to adapt to different space sizes on the side of the cabinet 1. The meshing transmission form of the gear and the rack is simple in structure and high in transmission accuracy.

[0118] In some embodiments of the present application, in combination with Figure 7 and Figure 10 , a through hole is formed on the mounting seat 81, and the transmission rack 92 is adapted to pass through the through hole, so that one end of the transmission rack 92 is in meshing transmission with the transmission gear 91, and the other end is connected with the baffle body 82.

[0119] In some embodiments of the present application, a sliding rail is provided on the mounting seat 81, and a sliding groove is provided on the baffle body 82. The sliding groove cooperates with the sliding rail to make the baffle body 82 move more smoothly and stably.

[0120] In some embodiments of the present application, referring to Figure 6 , Figure 9 , the baffle body 82 protrudes outward along the length direction of the cabinet 1, and the length of the cabinet 1 is L1. L1 satisfies: L1≥150mm. Thus, in the length direction of the cabinet 1, the length of the baffle body 82 protruding outward from the cabinet 1 is relatively long, so that the cabinet 1 has sufficient space to arrange the air conditioner pipeline.

[0121] In some embodiments of the present application, referring to Figure 6 , Figure 9 , L1 satisfies: L1≤300mm, thus, in the length direction of the casing 1, the length of the baffle body 82 protruding out of the casing 1 is not too long, and the total space occupied by the wall-mounted air conditioner 10 in the length direction is saved.

[0122] For example, L1 can be 150mm, 170mm, 190mm, 200mm, 230mm, 250mm, 280mm, 300mm, etc., and can also be other values between 150mm and 300mm, which will not be listed one by one here.

[0123] In the example of Figure 6 , Figure 9 , the casing 1 includes a first side plate 11 and a second side plate 12, which are arranged opposite to each other. The baffle device 8 is arranged on the left side of the first side plate 11, and the length of the baffle body 82 protruding to the left of the first side plate 11 is L1. The size of L1 can be changed by driving the baffle body 82 to move through the driving device and the transmission mechanism 9, so as to adapt to the installation space of the side of the casing 1.

[0124] In some embodiments of the present application, referring to Figure 6 , the length of the baffle body 82 protruding out of the casing 1 along the length direction of the casing 1 is L1, the length of the casing 1 is W, and L1 and W satisfy: L1≥0.15W, thus, in the length direction of the casing 1, the length of the baffle body 82 protruding out of the casing 1 is relatively long, so that the casing 1 has sufficient space to arrange the air conditioner pipeline.

[0125] In some embodiments of the present application, referring to Figure 6 , L1 satisfies: L1≤0.3W, thus, in the length direction of the casing 1, the length of the baffle body 82 protruding out of the casing 1 is not too long, and the total space occupied by the wall-mounted air conditioner 10 in the length direction is saved.

[0126] For example, L1 can be 0.15W, 0.18W, 0.2W, 0.25W, 0.3W, etc., and can also be other values between 0.15W and 0.3W, which will not be listed one by one here.

[0127] In the example of Figure 6 , the casing 1 includes a first side plate 11 and a second side plate 12, which are arranged opposite to each other. The baffle device 8 is arranged on the left side of the first side plate 11, and the length of the baffle body 82 protruding to the left of the first side plate 11 is L1, and the length of the casing 1 in the left-right direction is W.

[0128] In some embodiments of this application, reference is made to Figures 1-2 , Figure 5 As shown, the height of the baffle body 82 is equal to the height of the housing 1, both being H.

[0129] In some embodiments of this application, the outer wall designs of the mounting base 81, the baffle body 82, the front panel 4, and the air guide plate 6 are similar and made of the same material, which helps to improve the overall aesthetics of the wall-mounted air conditioner 10.

[0130] In some embodiments of this application, reference is made to Figures 7-10 As shown, the baffle body 82 includes a first plate 821 and a second plate 822. The second plate 822 is connected to the first plate 821 and is bent backward relative to the first plate 821. When adjusting the position of the baffle body 82, the second plate 822 can be fitted against or separated from the side wall or cabinet side wall. The first plate 821 and the second plate 822 can be constructed as an "L" shape, which is simple in structure.

[0131] In some embodiments of this application, reference is made to Figures 1-6 As shown, the front surface of the first plate 821 and the front surface of the front panel 4 are located in the same plane. Specifically, when the wall-mounted air conditioner 10 is in the closed state, the front surfaces of the baffle body 82, the air inlet grille 5, the front surface of the front panel 4, and the air guide plate 6 are located in the same plane, flush with the front surface of the cabinet 20, achieving perfect integration. When the wall-mounted air conditioner 10 is in the open state, the first air guide plate 61 opens upwards with an opening range of 0° to 60°, effectively reducing airflow short-circuiting; the second air guide plate 62 opens downwards with an opening angle of 0° to 120°, achieving wide-angle air supply in the room.

[0132] In some embodiments of this application, reference is made to Figures 7-9 As shown, the front surface of the first plate 821 is parallel to the front surface of the front panel 4.

[0133] In some embodiments of this application, reference is made to Figures 7-10 As shown, the second plate 822 is perpendicular to the first plate 821. In the front-rear direction of the wall-mounted air conditioner 10, the length of the second plate 822 is L2, which satisfies: L2≥30mm. Therefore, the length of the second plate 822 extending backward is not too short, ensuring that the second plate 822 has good stability when it is attached to the side wall or the side wall of the cabinet.

[0134] In some embodiments of this application, reference is made to Figures 7-10 As shown, L2 satisfies: L2≤100mm. Therefore, the length of the second plate 822 extending backward will not be too long, which is beneficial to saving materials.

[0135] For example, L2 can be 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc., and can also be other values between 30 mm and 100 mm, which are not listed here.

[0136] In some embodiments of the present application, with reference to Figures 8-9 As shown in FIG. 8, the mounting seat 81 includes a first front side 811, a transition surface 813, and a second front side 812, the second front side 812 is connected to the first front side 811 through the transition surface 813, the second front side 812 is recessed backward relative to the first front side 811, and the baffle body 82 is adapted to slide along the second front side 812 in the length direction of the cabinet 1. The second front side 812 guides the extension and retraction movement of the baffle body 82, so that the movement of the baffle body 82 is more stable.

[0137] In some embodiments of the present application, the front surface of the baffle body 82 is in the same plane as the first front side 811. In this way, when the baffle body 82 is attached to the transition surface 813, the front surface of the baffle body 82 and the first front side 811 are approximately the same surface, and the front surface of the wall-mounted air conditioner 10 is more aesthetically pleasing.

[0138] In some embodiments of the present application, with reference to Figures 7-9 As shown in FIG. 9, the front surface of the baffle body 82 is parallel to the first front side 811, thereby forming a stepped visual effect.

[0139] In some embodiments of the present application, with reference to Figures 7-9 As shown in FIG. 10, the baffle device 8 further includes an adapter plate 83, the mounting seat 81 is mounted to the cabinet 1 through the adapter plate 83, and the adapter plate 83 includes a fixed part 831, the fixed part 831 is mounted to the cabinet 1. The mounting seat 81 is directly or indirectly mounted to the fixed part 831, and the mounting seat 81 is indirectly mounted to the cabinet 1 through the adapter plate 83.

[0140] The fixed part 831 is detachably mounted to the cabinet 1, so that the user can install or dismount the baffle device 8 according to actual needs.

[0141] For example, the fixed part 831 can be mounted to the cabinet 1 by a screw fastener, a buckle, a rivet, etc.

[0142] In some embodiments of the present application, with reference to Figures 7-9 As shown in FIG. 11, the adapter plate 83 further includes an adapter part 832, the adapter part 832 is connected to the fixed part 831, the adapter part 832 is bent in the length direction of the cabinet 1 relative to the fixed part 831, and the adapter part 832 extends away from the cabinet 1, and the mounting seat 81 is mounted to the adapter part 832. Specifically, as shown in FIG. 12, the adapter part 832 is bent in the length direction of the cabinet 1 relative to the fixed part 831, and the mounting seat 81 is mounted to the adapter part 832. Figures 7-9As shown, both the adapter portion 832 and the fixing portion 831 are constructed as plate-shaped structures. The adapter portion 832 bends to the left relative to the fixing portion 831 and extends to the left. The adapter portion 832 and the fixing portion 831 form an "L"-shaped structure, which is simple in structure. By setting the adapter portion 832, the flexibility of the arrangement of the relative positions of the mounting base 81 and the adapter plate 83 is improved.

[0143] In real-world usage scenarios, such as Figures 1-2 , Figures 5-11 As shown, after the air conditioner body is installed, the mounting base 81 is installed on the adapter plate 83. The relative position of the baffle body 82 and the mounting base 81 is adjusted according to the space on the left side of the housing 1. Then, the adapter plate 83 is fixed to the first side plate 11 on the left side of the housing 1 with screws. The presence of the baffle body 82 can completely cover the installation gap reserved on the left side of the housing 1. The telescopic design of the baffle body 82 can adapt to spaces of different sizes, realizing the embedded development of the wall-mounted air conditioner 10.

[0144] The thickness of the air conditioner unit is D. In user scenarios, before installing a recessed wall-mounted unit, a space must be reserved with a height greater than or equal to H, a length ranging from (W+150mm) to (W+300mm), and a depth greater than D. The air conditioner unit is placed on top of the cabinet 20, making full use of the area between the cabinet 20 and the ceiling 303. The air inlet 41 and air outlet 42 are directly connected to the external environment, eliminating the need for additional air intake areas. This reduces the risk of dirt accumulation, greatly simplifying the user's cleaning process and improving cleaning efficiency. Only the filter and the front surface of the air conditioner need to be cleaned.
