Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a wall-mounted air conditioner. Background Technology

[0002] In related technologies, a wall-mounted air conditioner includes a casing, a base, and an air guide plate. The air guide plate is rotatably installed at the heat exchange air outlet of the casing and is used to open or close the heat exchange air outlet and adjust the air outlet direction at the heat exchange air outlet to guide the air. The heat exchange air outlet is connected to the air duct on the base.

[0003] However, when the existing air guide plate rotates, the base needs to leave a safe distance to avoid the rotation trajectory of the air guide plate, resulting in a large gap between the air duct curve of the air guide plate and the base. Wall-mounted air conditioners often have separate air guide decorative parts to connect the air duct curve with the casing, resulting in a complex overall structure and cumbersome assembly steps. Utility Model Content

[0004] This application aims to at least partially solve one of the aforementioned technical problems in the prior art. To this end, this application proposes a wall-mounted air conditioner where the base and casing can avoid the air guide plate, eliminating the need for a separate air guide decorative component.

[0005] The wall-mounted air conditioner according to an embodiment of this application includes a casing, the interior of which is formed a cavity, and the casing is provided with a heat exchange air inlet and a heat exchange air outlet.

[0006] The wall-mounted air conditioner also includes a base, which is disposed in the accommodating cavity. A volute air duct is formed on the base, and the volute air duct is connected to the heat exchange air inlet and the heat exchange air outlet.

[0007] The wall-mounted air conditioner also includes a heat exchange fan, which is installed inside the volute air duct.

[0008] The wall-mounted air conditioner also includes a first motor, which is disposed in the accommodating cavity and located at one end of the heat exchange fan along its length. The first motor is used to drive the heat exchange fan to rotate so that the air inside the air conditioner exchanges heat with the indoor space.

[0009] The wall-mounted air conditioner also includes a first air guide plate, which is rotatably disposed at the heat exchange air outlet.

[0010] The wall-mounted air conditioner also includes a second air guide plate, which is disposed at the heat exchange air outlet and located above the first air guide plate. The second air guide plate is rotatably connected to the base at a second pivot axis. The second air guide plate has a second closed limit position and a second open limit position, and is adapted to rotate between the second closed limit position and the second open limit position.

[0011] When the first air guide plate and the second air guide plate rotate to abut against each other, the first air guide plate and the second air guide plate together close the heat exchange outlet; when the first air guide plate and the second air guide plate separate, the first air guide plate and the second air guide plate open the heat exchange outlet.

[0012] The housing includes a housing clearance plate, which is located above the heat exchange outlet and is used to at least partially enclose the heat exchange outlet.

[0013] The base includes a base clearance plate, which is adjacent to and located behind the housing clearance plate. The base clearance plate is used to at least partially enclose the volute air duct.

[0014] The lower surface of the housing clearance plate overlaps with the lower surface of the base clearance plate to form an upwardly concave arc-shaped surface.

[0015] When the second air guide plate rotates from the second closed limit position to the second open limit position, the upper end of the second air guide plate rotates towards the inside of the volute air duct, and the arc-shaped surface avoids the upper end of the second air guide plate, thereby allowing the second air guide plate to rotate smoothly; when the second air guide plate is in the second closed limit position, the upper end of the second air guide plate is adjacent to the front end of the housing clearance plate, thereby making the gap between the second air guide plate and the housing clearance plate smaller, and the wall-mounted air conditioner has a more beautiful appearance.

[0016] According to the wall-mounted air conditioner of the present application embodiment, the arc-shaped surface formed by the overlapping of the lower surface of the base clearance plate and the lower surface of the casing clearance plate can avoid the second air guide plate, eliminating the need for a separate air guide decorative piece, thereby reducing the number of parts and saving assembly steps.

[0017] According to some embodiments of this application, the second air guide plate is adapted to be separated from both the housing clearance plate and the base clearance plate. This prevents the second air guide plate from colliding with the housing clearance plate and the base clearance plate during rotation, thus avoiding collision noises. When the second air guide plate is in the second closed limit position, the gap between the upper end of the second air guide plate and the front end of the housing clearance plate is no more than 5mm. This ensures a small gap between the second air guide plate and the housing, resulting in a more aesthetically pleasing appearance for the wall-mounted air conditioner.

[0018] According to some embodiments of this application, when the upper end of the second air guide plate is located directly below the housing clearance plate and the second air guide plate rotates from the second closed limit position to the second open limit position, the vertical gap between the upper end of the second air guide plate and the housing clearance plate increases. Thus, when the second air guide plate rotates from the second closed limit position to the second open limit position, the housing clearance plate can provide sufficient clearance for the second air guide plate.

[0019] According to some embodiments of this application, when the upper end of the second air guide plate is located directly below the base clearance plate and the second air guide plate rotates from the second closed limit position to the second open limit position, the vertical gap between the upper end of the second air guide plate and the base clearance plate increases. Thus, when the second air guide plate rotates from the second closed limit position to the second open limit position, the base clearance plate can provide sufficient safety clearance for the second air guide plate.

[0020] According to some embodiments of this application, the wall-mounted air conditioner further includes a panel, which is installed on the side of the housing away from the base. The panel is used to at least partially cover the housing. In the vertical direction of the wall-mounted air conditioner, the lower end of the panel is not lower than the front end of the housing clearance plate, thereby preventing the panel from blocking the air outlet at the heat exchange outlet.

[0021] According to some embodiments of this application, the wall-mounted air conditioner further includes a first insulation structure, which is disposed on the side of the casing relief plate away from the heat exchange air outlet. The first insulation structure is used to insulate the heat exchange air outlet, thereby reducing the generation of condensate in the heat exchange air outlet.

[0022] According to some embodiments of this application, the wall-mounted air conditioner further includes a second insulation structure, which is disposed on the side of the base clearance plate away from the volute air duct. The second insulation structure is used to insulate the volute air duct, thereby reducing the generation of condensate in the volute air duct.

[0023] According to some embodiments of this application, the casing is provided with a first mounting groove, and the first insulation structure is disposed in the first mounting groove. The wall-mounted air conditioner also includes a panel, which is installed on the side of the casing opposite to the base. The panel covers the first mounting groove and the first insulation structure. The first mounting groove provides installation space for the first insulation structure. The panel and the casing work together to ensure that the first insulation structure can be firmly installed on the casing and prevent it from falling off.

[0024] According to some embodiments of this application, the first air guide plate is rotatably connected to the base at a first pivot axis, and the second pivot axis is located in front of and above the first pivot axis.

[0025] When the first air guide plate and the second air guide plate rotate to abut against each other, the second air guide plate is in the second closed limit position.

[0026] According to some embodiments of this application, the heat exchange air inlet is located at the top of the housing, and the heat exchange air outlet is located at the lower front of the housing.

[0027] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0057] Some embodiments of this application provide a wall-mounted air conditioner 10.

[0058] Typically, air conditioners are split-type air conditioners, which include an indoor unit and an outdoor unit. The indoor and outdoor units are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0059] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling device. The compressor, outdoor heat exchanger, throttling device, and indoor heat exchanger are connected in sequence to form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger, respectively, to achieve the air conditioner's cooling mode or heating mode.

[0060] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0061] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0062] In some embodiments, the outdoor heat exchanger may include heat exchange fins to increase the contact area between outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0063] The outdoor fan is configured to draw in outside air into the outdoor unit and expel the outdoor air, which has been heated by the outdoor heat exchanger, to the outside. The outdoor fan provides power for the flow of outdoor air.

[0064] A throttling device connects the outdoor and indoor heat exchangers. It regulates the refrigerant pressure flowing through both devices, thereby controlling the refrigerant flow rate between them. The flow rate and pressure of the refrigerant between the outdoor and indoor heat exchangers affect their heat exchange performance. The throttling device can be a throttling tube, an electronic valve, etc. When the throttling device is an electronic valve, its opening is adjustable to regulate the refrigerant flow rate and pressure.

[0065] In some designs, the air conditioner may include a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform a cooling mode or a heating mode.

[0066] An indoor heat exchanger is configured to exchange heat between indoor air and a refrigerant transported within the indoor heat exchanger. In some embodiments, the indoor heat exchanger may include heat exchange fins to increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0067] The heat exchange fan is configured to draw indoor air into the indoor unit and deliver the indoor air, after heat exchange with the indoor heat exchanger, into the room, providing power for the flow of indoor air.

[0068] The following is combined with Figures 1-19 A detailed description of the wall-mounted air conditioner 10 according to an embodiment of this application.

[0069] The wall-mounted air conditioner 10 of this application is an indoor unit. The wall-mounted air conditioner 10 is typically installed on a wall, for example, in the upper area of ​​an interior wall.

[0070] Reference Figures 1-3 , Figures 12-16 As shown, the wall-mounted air conditioner 10 according to the embodiment of this application includes a housing 1, and an accommodating cavity is formed inside the housing 1. The housing 1 can play a protective role and constitute the overall external structure of the wall-mounted air conditioner 10.

[0071] Typically, the casing 1 is a long, rectangular shell, with its length running horizontally along the wall. Figures 1-3 The left and right directions are indicated in the diagram. In actual products, in order to drain condensate, in some embodiments the casing 1 is mounted horizontally on the wall, forming a small angle with the horizontal plane.

[0072] The wall-mounted air conditioner 10 also includes an indoor heat exchanger (not shown in the figure), which is disposed within a housing cavity. As described above, the indoor heat exchanger is a loop in the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger to cool or heat the air flowing through its surface. In the wall-mounted air conditioner 10, the indoor heat exchanger typically extends along the length of the casing 1.

[0073] For example, the indoor heat exchanger is a two-fold or three-fold heat exchanger, and each fold of the indoor heat exchanger is a plate-like structure extending along the length direction.

[0074] The housing 1 is provided with a heat exchange air inlet 14 and a heat exchange air outlet 15. Indoor air can enter the accommodating cavity through the heat exchange air inlet 14 and then be blown out of the room through the heat exchange air outlet 15 to achieve internal circulation of indoor air.

[0075] The wall-mounted air conditioner 10 also includes a base 83, which is disposed within the accommodating cavity. A volute-like air duct 831 is formed on the base 83, and the volute-like air duct 831 is connected to both the heat exchange air inlet 14 and the heat exchange air outlet 15. The base 83 is fixed relative to the casing 1; in some embodiments, the base 83 is fixedly connected to the casing 1. The base 83 serves as an internal mounting support structure, and the indoor heat exchanger can be mounted on the base 83. After indoor air enters the casing 1, its flow direction is guided by the volute-like air duct 831, ensuring minimal resistance when the indoor air flows through the indoor heat exchanger.

[0076] The wall-mounted air conditioner 10 also includes a heat exchange fan 84, which is disposed within the volute duct 831. The heat exchange fan 84 is rotatable relative to the base 83. When the heat exchange fan 84 rotates, it drives indoor air from the heat exchange inlet 14 into the receiving cavity, and then blows it out of the room from the heat exchange outlet 15. In the wall-mounted air conditioner 10, the heat exchange fan 84 is typically arranged to extend along the length of the casing 1.

[0077] By providing a heat exchange outlet 15 and a heat exchange inlet 14 on the casing 1, the heat exchange fan 84 can draw indoor air into the casing 1 through the heat exchange inlet 14 when it is running. After heat exchange between the indoor air and the indoor heat exchanger, the heat-exchanged air is delivered back into the room through the heat exchange outlet 15. This allows for the regulation of the indoor ambient temperature. The indoor heat exchanger can function as an evaporator, providing a cooling airflow to the indoor space through the heat exchange outlet 15, or it can function as a condenser, providing a heating airflow to the indoor space through the heat exchange outlet 15.

[0078] In some embodiments, the heat exchange fan 84 is, for example, a cross-flow fan, which has low noise and large air volume, and the air velocity of the cross-flow fan is more uniformly distributed along the axial direction of the cross-flow fan, which is beneficial to increasing the air delivery distance and air delivery range. Moreover, when a cross-flow fan is used and the cross-flow fan is arranged along the length direction of the casing 1, it is beneficial for the driven airflow to flow through the entire indoor heat exchanger, ensuring the balance of heat exchange efficiency of each part of the indoor heat exchanger.

[0079] The wall-mounted air conditioner 10 also includes a first motor (not shown in the figure). The first motor is disposed within the accommodating cavity and located at one end of the heat exchange fan 84 along its length. This facilitates the installation and maintenance of the first motor, and the wall-mounted air conditioner 10 as a whole does not need to become excessively tall or thick due to the placement of the first motor. Here, the height direction of the wall-mounted air conditioner 10 is consistent with the vertical direction, and the thickness direction of the wall-mounted air conditioner 10 is consistent with the front-to-back direction. The first motor is used to drive the heat exchange fan 84 to rotate, so that the air inside the air conditioner exchanges heat with the indoor space. In other words, the first motor is used to provide driving force to the heat exchange fan 84 to drive the heat exchange fan 84 to rotate.

[0080] In some embodiments of this application, reference is made to Figures 1-4 , Figures 6-11 , Figure 18 As shown, the wall-mounted air conditioner 10 also includes a first air guide plate 3, which is rotatably disposed at the heat exchange air outlet 15, thereby changing the size of the obstruction of the heat exchange air outlet 15 by the first air guide plate 3, so as to adjust the air volume and air direction at the heat exchange air outlet 15.

[0081] Reference Figures 1-11 , Figure 19 As shown, the wall-mounted air conditioner 10 also includes a second air guide plate 4, which is disposed at the heat exchange air outlet 15 and located above the first air guide plate 3. The second air guide plate 4 is rotatably connected to the base 83 at the second pivot axis 52. The second air guide plate 4 can rotate around the second pivot axis 52, thereby changing the degree of obstruction of the heat exchange air outlet 15 by the second air guide plate 4, so as to adjust the air volume and air direction at the heat exchange air outlet 15. The second air guide plate 4 has a second closed limit position and a second open limit position, and the second air guide plate 4 is adapted to rotate between the second closed limit position and the second open limit position.

[0082] The area of ​​the second air guide plate 4 obstructing the heat exchange outlet 15 at the second closed limit position is greater than the area of ​​the second air guide plate 4 obstructing the heat exchange outlet 15 at the second open limit position. When the second air guide plate 4 is in the second closed limit position, as... Figures 1-6 , Figure 9 As shown in the diagram, the second air guide plate 4 has the largest obstruction area on the heat exchange outlet 15. When the second air guide plate 4 is in the second open limit position, as... Figures 7-8 As shown in the diagram, the second air guide plate 4 has the smallest obstruction area on the heat exchange outlet 15.

[0083] Reference Figures 1-4 , Figure 6 As shown, when the first air guide plate 3 and the second air guide plate 4 rotate to abut against each other, the first air guide plate 3 and the second air guide plate 4 together close the heat exchange air outlet 15. The heat exchange air outlet 15 is blocked by the first air guide plate 3 and the second air guide plate 4, and the air in the volute duct 831 cannot enter the room through the heat exchange air outlet 15.

[0084] Reference Figures 7-11 As shown, when the first air guide plate 3 and the second air guide plate 4 separate, the first air guide plate 3 and the second air guide plate 4 open the heat exchange air outlet 15, and the air in the volute duct 831 can enter the room through the heat exchange air outlet 15.

[0085] Reference Figures 3-5As shown, the housing 1 includes a housing clearance plate 16, which is located above the heat exchange outlet 15 and serves to at least partially enclose the heat exchange outlet 15. When the second air guide plate 4 is not in the second closed limit position, the air in the volute duct 831 blows outward through the heat exchange outlet 15 and passes over the lower surface of the housing clearance plate 16. When the second air guide plate 4 rotates below the housing clearance plate 16, the housing clearance plate 16 can avoid the rotation trajectory of the second air guide plate 4, allowing the second air guide plate 4 to rotate smoothly.

[0086] The base 83 includes a base clearance plate 833, which is adjacent to the housing clearance plate 16 and located behind the housing clearance plate 16. The base clearance plate 833 is used to at least partially enclose the volute duct 831. When the second air guide plate 4 is not in the second closed limit position, the air in the volute duct 831 blows outward through the heat exchange outlet 15 and passes over the lower surface of the base clearance plate 833. When the second air guide plate 4 rotates below the base clearance plate 833, the base clearance plate 833 can avoid the rotation trajectory of the second air guide plate 4, allowing the second air guide plate 4 to rotate smoothly.

[0087] In some embodiments, the housing clearance plate 16 is an arc-shaped plate extending in the left-right direction of the wall-mounted air conditioner 10, and the base clearance plate 833 is an arc-shaped plate extending in the left-right direction of the wall-mounted air conditioner 10. The lower surface of the housing clearance plate 16 and the lower surface of the base clearance plate 833 overlap to form an upwardly concave arc-shaped surface. It is understood that the "arc-shaped surface" referred to here does not necessarily strictly refer to a circular arc surface, nor does it necessarily have to be a fully arc-shaped surface. For example, it can be a combination of a partially arc-shaped surface and a flat surface, or it can be a fully circular arc surface.

[0088] When the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the upper end of the second air guide plate 4 rotates toward the inside of the volute tongue air duct 831, and the arc-shaped surface formed by the overlap of the housing clearance plate 16 and the base clearance plate 833 avoids the upper end of the second air guide plate 4; when the second air guide plate 4 is in the second closed limit position, the upper end of the second air guide plate 4 is adjacent to the front end of the housing clearance plate 16.

[0089] Reference Figures 4-5 , Figure 11As shown, when the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the second air guide plate 4 rotates counterclockwise, and the upper end of the second air guide plate 4 (denoted as the fourth end 41b) rotates towards the interior of the volute tongue air duct 831. The housing clearance plate 16 can serve as an extension plate of the volute tongue air duct 831. After the housing clearance plate 16 is connected to the base clearance plate 833, an arc-shaped surface (i.e., the air duct curved surface) is formed. This arc-shaped surface can avoid the rotation of the second air guide plate 4. In this way, the feature of avoiding the rotation of the second air guide plate 4 is set on two parts, the base 83 and the housing 1, eliminating the need to design a separate air guide decorative part, reducing the cost of finished products and greatly improving production efficiency.

[0090] When the second air guide plate 4 rotates between the second closed limit position and the second open limit position, the rotation trajectory of the fourth end 41b of the second air guide plate 4 is as follows: Figure 5 , Figure 11 The arc-shaped trajectory P shown in the figure.

[0091] When the second air guide plate 4 is in the second closed limit position, such as Figures 4-5 As shown, the fourth end 41b of the second air guide plate 4 is adjacent to the front end of the housing clearance plate 16, which makes the gap between the second air guide plate 4 and the housing clearance plate 16 smaller, and the wall-mounted air conditioner 10 has a more beautiful appearance.

[0092] It is understandable that "the upper end of the second air guide plate 4 is adjacent to the front end of the housing clearance plate 16" means that the upper end of the second air guide plate 4 is close to the front end of the housing clearance plate 16, and the two can be in contact or separated.

[0093] According to the wall-mounted air conditioner 10 of this application embodiment, the arc-shaped surface formed by the overlapping of the lower surface of the base clearance plate 833 and the lower surface of the casing clearance plate 16 can avoid the second air guide plate 4, eliminating the need for a separate air guide decorative piece, thereby reducing the number of parts and saving assembly steps.

[0094] In some embodiments of this application, the second air guide plate 4 is adapted to be separated from the housing clearance plate 16 and the base clearance plate 833. In this way, the second air guide plate 4 will not collide with the housing clearance plate 16 and the base clearance plate 833 when it rotates, thus avoiding collision noise.

[0095] In some embodiments of this application, when the second air guide plate 4 is in the second closed limit position, the gap between the upper end of the second air guide plate 4 and the front end of the housing clearance plate 16 is no greater than 5mm. Specifically, when the second air guide plate 4 is in the second closed limit position, in the vertical direction of the wall-mounted air conditioner 10, the gap between the upper end of the second air guide plate 4 and the front end of the housing clearance plate 16 is no greater than 5mm, for example, the gap can be 1mm, 1.5mm, 2mm, 2.5mm, etc. This ensures that the gap between the second air guide plate 4 and the housing 1 is small, making the wall-mounted air conditioner 10 more aesthetically pleasing.

[0096] In some embodiments of this application, when the upper end of the second air guide plate 4 is located directly below the housing clearance plate 16 and the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the vertical gap between the upper end of the second air guide plate 4 and the housing clearance plate 16 increases. Thus, when the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the housing clearance plate 16 can provide sufficient safety clearance for the second air guide plate 4.

[0097] It is understandable that "the upper end of the second air guide plate 4 is located directly below the housing clearance plate 16" means that the projection of the upper end of the second air guide plate 4 on the horizontal plane is within the projection range of the housing clearance plate 16 on the horizontal plane.

[0098] In some embodiments of this application, when the upper end of the second air guide plate 4 is located directly below the base clearance plate 833 and the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the vertical gap between the upper end of the second air guide plate 4 and the base clearance plate 833 increases. Thus, when the second air guide plate 4 rotates from the second closed limit position to the second open limit position, the base clearance plate 833 can provide sufficient safety clearance for the second air guide plate 4.

[0099] It is understandable that "the upper end of the second air guide plate 4 is located directly below the housing clearance plate 16" means that the projection of the upper end of the second air guide plate 4 on the horizontal plane is within the projection range of the base clearance plate 833 on the horizontal plane.

[0100] In some embodiments of this application, reference is made to Figures 4-5 , Figure 11 As shown, the wall-mounted air conditioner 10 also includes a panel 81, which is installed on the side of the housing 1 away from the base 83. The panel 81 is used to at least partially cover the housing 1. In the vertical direction of the wall-mounted air conditioner 10, the lower end of the panel 81 is not lower than the front end of the housing clearance plate 16, thereby preventing the panel 81 from blocking the air outlet 15.

[0101] The front end of the lower surface of the housing clearance plate 16 extends towards the lower front of the wall-mounted air conditioner 10. The lower surface of the base clearance plate 833 is connected to the lower surface of the housing clearance plate 16. In this way, when the second air guide plate 4 is not in the second closed limit position, the shape of the lower surface of the housing clearance plate 16 and the lower surface of the base clearance plate 833 can also guide the airflow direction, so as to avoid the cold air blowing directly onto the panel 81 and causing condensation to form on the panel 81.

[0102] Reference Figures 3-11 , Figure 19 As shown, the second air guide plate 4 includes a second body 41, which extends along the length of the wall-mounted air conditioner 10. In the width direction of the second body 41, the second body 41 has a third end 41a and a fourth end 41b. The distance of the second pivot shaft 52 from either the third end 41a or the fourth end 41b is greater than the distance of the second pivot shaft 52 from the center of the second body 41.

[0103] In some embodiments, the second pivot axis 52 is close to the center of the second body 41 in the width direction of the second body 41.

[0104] Alternatively, in some other embodiments, the distance of the second pivot axis 52 from the third end 41a is equal to the distance of the second pivot axis 52 from the fourth end 41b, and the second pivot axis 52 is located at the center of the second body 41 in the width direction of the second body 41.

[0105] Reference Figures 3-11 , Figure 19 As shown, the second air guide plate 4 also includes a second support arm 42, which is connected to the second body 41. The second support arm 42 is rotatably connected to the base 83 at the second pivot axis 52. The second pivot axis 52 is spaced apart from the second body 41. When the second air guide plate 4 rotates, the second body 41 rotates around the second pivot axis 52.

[0106] Reference Figures 7-8 , Figures 10-11 As shown, the surface of the second body 41 that is away from the second support arm 42 is the second outer side 45. When the second air guide plate 4 is in the second open limit position, or when the second air guide plate 4 is in any intermediate position between the second closed limit position and the second open limit position, there is a gap between the second outer side 45 and the housing clearance plate 16, and between the second outer side 45 and the base clearance plate 833 for air to flow through.

[0107] In some embodiments of this application, the wall-mounted air conditioner 10 further includes a first insulation structure, which is disposed on the side of the casing relief plate 16 away from the heat exchange air outlet 15. The first insulation structure is used to insulate the heat exchange air outlet 15, thereby reducing the amount of condensate generated in the heat exchange air outlet 15.

[0108] In some embodiments of this application, the wall-mounted air conditioner 10 further includes a second insulation structure, which is disposed on the side of the base clearance plate 833 away from the volute duct 831. The second insulation structure is used to insulate the volute duct 831, thereby reducing the amount of condensate generated in the volute duct 831.

[0109] Reference Figure 14 As shown, the base 83 is provided with a second mounting groove 834, and the second insulation structure is disposed in the second mounting groove 834. The second mounting groove 834 provides installation space for the second insulation structure, thereby the second insulation structure can be firmly installed on the base 83 and prevent it from falling off.

[0110] In some embodiments of this application, reference is made to Figure 5 , Figures 16-17 As shown, the casing 1 has a first mounting groove 17, and a first insulation structure is disposed within the first mounting groove 17. The wall-mounted air conditioner 10 also includes a panel 81, which is installed on the side of the casing 1 opposite to the base 83. The panel 81 covers the first mounting groove 17 and the first insulation structure. The first mounting groove 17 provides installation space for the first insulation structure, thereby allowing the first insulation structure to be securely installed on the casing 1 and preventing it from falling off.

[0111] In some embodiments of this application, reference is made to Figures 1-4 , Figures 6-11 , Figure 18 As shown, the first air guide plate 3 is located at the heat exchange outlet 15. The first air guide plate 3 can rotate around the first pivot axis 51. The first air guide plate 3 is rotatably connected to the base 83 at the first pivot axis 51. The second pivot axis 52 is located in front of and above the first pivot axis 51. The first air guide plate 3 has a first closed limit position and a first open limit position. The first air guide plate 3 is adapted to rotate between the first closed limit position and the first open limit position. When the first air guide plate 3 is in the first open limit position, such as... Figure 9 As shown, the first air guide plate 3 provides the least obstruction to the heat exchange outlet 15. When the first air guide plate 3 is in the first closed limit position, as... Figure 1 , Figures 3-4 , Figures 6-8 As shown, the first air guide plate 3 obstructs the heat exchange outlet 15 the most.

[0112] Reference Figures 1-4 , Figure 6 As shown, when the first air guide plate 3 and the second air guide plate 4 rotate to abut against each other, the second air guide plate 4 is in the second closed limit position.

[0113] Reference Figures 3-4 , Figures 6-11As shown, the axis of the first pivot shaft 51 is parallel to the axis of the second pivot shaft 52 and both extend along the length of the wall-mounted air conditioner 10. In the front-rear direction of the wall-mounted air conditioner 10, the second pivot shaft 52 is located in front of the first pivot shaft 51, and in the vertical direction of the wall-mounted air conditioner 10, the second pivot shaft 52 is located above the first pivot shaft 51. The first pivot shaft 51 and the second pivot shaft 52 are separated not only in the front-rear direction of the wall-mounted air conditioner 10, but also in the vertical direction. Therefore, the first air guide plate 3 and the second air guide plate 4 are less likely to interfere with each other, and the rotation range of the first air guide plate 3 and the second air guide plate 4 is relatively wide, which facilitates guiding the air blown out from the heat exchange outlet 15 to the target position, resulting in better air control effect of the first air guide plate 3 and the second air guide plate 4.

[0114] In some embodiments, refer to Figure 18 As shown, the wall-mounted air conditioner 10 also includes a first drive device 91, which drives the first air guide plate 3 to rotate. The first drive device 91 can be fixedly installed on the base 83. The first drive device 91 can be a motor, or a combination of a motor and a reducer. The output shaft of the first drive device 91 is connected to the first air guide plate 3 so that when the output shaft of the first drive device 91 rotates, it drives the first air guide plate 3 to rotate around the first pivot shaft 51.

[0115] The number of first drive units 91 can be one or more, for example, in Figure 18 In the example, there is one first driving device 91, which is located at one end of the first air guide plate 3 along its length. In some embodiments not shown in the figure, there are two first driving devices 91, which are located at opposite ends of the first air guide plate 3 along its length, and the two first driving devices 91 together drive the first air guide plate 3 to rotate.

[0116] In other embodiments, a first transmission mechanism may be provided between the output shaft of the first drive device 91 and the first air guide plate 3, so that the power of the first drive device 91 is transmitted to the first air guide plate 3 via the first transmission mechanism. The first transmission mechanism may be a gear transmission assembly to reduce the speed and increase the torque of the power of the first drive device 91 before transmitting it to the first air guide plate 3.

[0117] There can be one or more first pivot axes 51. When there are multiple first pivot axes 51, the multiple first pivot axes 51 are arranged coaxially.

[0118] The rotation angle of the first air guide plate 3 can be controlled by controlling the rotation angle of the output shaft of the first drive device 91.

[0119] In some embodiments, refer to Figure 19As shown, the wall-mounted air conditioner 10 also includes a second drive device 92, which drives the second air guide plate 4 to rotate. The second drive device 92 can be fixedly installed on the base 83. The second drive device 92 can be a motor, or a combination of a motor and a reducer. The output shaft of the second drive device 92 is connected to the second air guide plate 4 so that when the output shaft of the second drive device 92 rotates, it drives the second air guide plate 4 to rotate around the second pivot shaft 52.

[0120] The number of second drive units 92 can be one or more, for example, in Figure 19 In the example, there is one second driving device 92, which is disposed at one end of the second air guide plate 4 along its length. In some embodiments not shown in the figure, there are two second driving devices 92, which are located at opposite ends of the second air guide plate 4 along its length, and the two second driving devices 92 together drive the second air guide plate 4 to rotate.

[0121] In other embodiments, a second transmission mechanism may be provided between the output shaft of the second drive device 92 and the second air guide plate 4, so that the power of the second drive device 92 is transmitted to the second air guide plate 4 via the second transmission mechanism. The second transmission mechanism may be a gear transmission assembly to reduce the speed and increase the torque of the power of the second drive device 92 before transmitting it to the second air guide plate 4.

[0122] There can be one or more second pivot axes 52. When there are multiple second pivot axes 52, the multiple second pivot axes 52 are arranged coaxially.

[0123] The rotation angle of the second air guide plate 4 can be controlled by controlling the rotation angle of the output shaft of the second drive device 92.

[0124] In some embodiments of this application, reference is made to Figures 3-4 , Figures 6-11 , Figure 18As shown, the first air guide plate 3 includes a first body 31, which extends along the length of the wall-mounted air conditioner 10. In the width direction of the first body 31, the first body 31 has a first end 31a and a second end 31b. The distance of the first pivot shaft 51 from the first end 31a is greater than the distance of the first pivot shaft 51 from the second end 31b. In the width direction of the first body 31, the first pivot shaft 51 is eccentrically positioned relative to the first body 31, being closer to the second end 31b. When the first air guide plate 3 rotates around the first pivot shaft 51, the rotation radius of the first end 31a of the first body 31 is larger, while the rotation radius of the second end 31b of the first body 31 is smaller. This results in a larger range of motion for the first end 31a of the first body 31, allowing the first air guide plate 3 to sweep out a larger fan-shaped area around the first pivot shaft 51 when rotating. When it is necessary to increase the airflow at the heat exchange outlet 15, the first air guide plate 3 can be rotated to a position that minimizes obstruction of the heat exchange outlet 15.

[0125] Reference Figures 3-4 , Figures 6-11 , Figure 18 As shown, the first air guide plate 3 also includes a first support arm 32, which is connected to the first body 31. The first support arm 32 is rotatably connected to the base 83 at the first pivot axis 51. The first pivot axis 51 is spaced apart from the first body 31. When the first air guide plate 3 rotates, the first body 31 rotates around the first pivot axis 51.

[0126] In some embodiments, both the first body 31 and the second body 41 are elongated, and their length directions are consistent with the length direction of the wall-mounted air conditioner 10. The heat exchange outlet 15 is an elongated opening, and its length direction is consistent with the length direction of the wall-mounted air conditioner 10. The lengths of the first body 31 and the second body 41 are equal to the length of the heat exchange outlet 15. Through the specially designed shape and rotation angle of the first air guide plate 3 and the second air guide plate 4, a wider air delivery range and adaptation to special usage scenarios are achieved.

[0127] In some embodiments of this application, reference is made to Figure 6 , Figure 8 As shown, the surface of the first body 31 facing the first support arm 32 is provided with an arc-shaped protrusion structure 311. The distance of the arc-shaped protrusion structure 311 from the first end 31a is less than the distance of the first pivot shaft 51 from the second end 31b. The arc-shaped protrusion structure 311 can guide the airflow blowing onto it, changing its direction. For example, when the wall-mounted air conditioner 10 is in cooling mode, the first body 31 of the first air guide plate 3 is rotated to a roughly horizontal position, and the second body 41 of the second air guide plate 4 is rotated to a roughly horizontal position, such as... Figures 7-8As shown, when the air in the volute duct 831 blows to the arc-shaped protrusion 311, the raised design of the arc-shaped protrusion 311 provides a better airflow control angle. The arc-shaped protrusion 311 can guide the cold air upward, thus achieving the effect of upward-blowing cold air, allowing more cold air to be blown towards the ceiling, resulting in better cooling effect and preventing direct airflow. Subsequently, the cold air, being heavier, will descend and exchange heat with the warm air in the lower part of the room to cool the indoor air, providing users with a cooling sensation from top to bottom. At the same time, the upward-blowing of the cold air also prevents it from blowing directly on people, which helps to improve the user experience.

[0128] When the wall-mounted air conditioner 10 is in heating mode, the first body 31 of the first air guide plate 3 is rotated to a roughly vertical position, and the second body 41 of the second air guide plate 4 is rotated to a roughly vertical position, such as... Figure 9 As shown, when the air in the volute duct 831 blows to the heat exchange outlet 15, the first air guide plate 3 and the second air guide plate 4 can guide the hot air vertically downward, thereby achieving the effect of vertical downward pressure of the hot air, providing better heating effect and anti-direct blowing experience, so that more hot air is blown towards the ground. Subsequently, the hot air will rise due to its lightness and exchange heat with the cold air in the upper part of the room to achieve the heating of the indoor air, and the user will feel the hot air experience from the bottom up.

[0129] When the first air guide plate 3 and the second air guide plate 4 are at the maximum air outlet angle, such as Figure 10 As shown, the first air guide plate 3 is located outside the extension line of the volute tongue air duct 831. Both sides of the second air guide plate 4 are separated from the inner wall of the volute tongue air duct 831, and airflow passes through both sides of the second air guide plate 4. At this time, the heat exchange air outlet 15 has an extra-large air outlet and low wind resistance, resulting in a higher air volume. The lower surface of the housing clearance plate 16 and the lower surface of the base clearance plate 833 can form an air passage with the second air guide plate 4, thus giving the heat exchange air outlet 15 a large air outlet space.

[0130] In some embodiments of this application, reference is made to Figure 6 , Figure 8 As shown, the thickness of the fourth end 41b of the second air guide plate 4 is less than the thickness of the third end 41a. Therefore, when the second air guide plate 4 rotates to a position where the fourth end 41b is closer to the heat exchange fan 84 and the third end 41a is farther from the heat exchange fan 84, that is, when the second air guide plate 4 rotates to a position where... Figure 8 When positioned as shown, it helps to reduce the wind resistance at the fourth end 41b of the second air guide plate 4.

[0131] In some embodiments of this application, the outer surface of the fourth end 41b of the second air guide plate 4 is designed at least partially as a thinned arc-shaped structure, which is beneficial to further reduce wind resistance.

[0132] In some embodiments of this application, reference is made to Figures 3-4 , Figures 6-11 , Figure 18 As shown, the first body 31 includes a first frame 33 and a first outer trim panel 34, the first frame 33 and the first outer trim panel 34 are connected, and a first support arm 32 is disposed on the side of the first frame 33 opposite to the first outer trim panel 34. An arc-shaped protrusion structure 311 is disposed on the surface of the first frame 33 opposite to the first outer trim panel 34.

[0133] In some embodiments, the first frame 33 and the first exterior panel 34 are detachably connected, thereby facilitating the replacement of vulnerable parts in the first frame 33 and the first exterior panel 34 and saving costs. For example, the first frame 33 and the first exterior panel 34 can be snap-fitted together. Different visual effects can be achieved by replacing the first exterior panel 34 with one of different appearances.

[0134] In some embodiments of this application, reference is made to Figures 3-11 , Figure 19 As shown, the second body 41 includes a second frame 43 and a second outer trim panel 44, the second frame 43 and the second outer trim panel 44 are connected, and the second support arm 42 is disposed on the side of the second frame 43 opposite to the second outer trim panel 44.

[0135] In some embodiments, the second frame 43 and the second exterior panel 44 are detachably connected, thereby facilitating the replacement of vulnerable parts in the second frame 43 and the second exterior panel 44 and saving costs. For example, the second frame 43 and the second exterior panel 44 can be snap-fitted together. Different visual effects can be achieved by replacing the second exterior panel 44 with one of different appearances.

[0136] In some embodiments of this application, reference is made to Figure 6 As shown, the first air guide plate 3 has a first outer surface 35, and the second air guide plate 4 has a second outer surface 45. When the first air guide plate 3 and the second air guide plate 4 close the heat exchange outlet 15, the included angle between the first outer surface 35 and the second outer surface 45 is 80° to 100°. For example, the included angle between the first outer surface 35 and the second outer surface 45 can be 80°, 85°, 90°, 95°, 100°, etc. The first outer surface 35 is the surface of the first body 31 that faces away from the first support arm 32, and the second outer surface 45 is the surface of the second body 41 that faces away from the second support arm 42.

[0137] When the angle between the first outer side 35 and the second outer side 45 is less than 80°, when the first air guide plate 3 and the second air guide plate 4 abut against each other, a sharp angle is formed between the first outer side 35 and the second outer side 45. This can easily cause the first outer side 35 to bulge downward relative to the bottom of the casing 1, or cause the second outer side 45 to bulge forward relative to the front of the casing 1, resulting in an irregular and unattractive overall appearance of the wall-mounted air conditioner 10.

[0138] When the included angle between the first outer side 35 and the second outer side 45 is greater than 100°, when the first air guide plate 3 and the second air guide plate 4 abut against each other, a large obtuse angle is formed between the first outer side 35 and the second outer side 45. It is difficult for the first outer side 35 to form a coplanar or parallel structure with the bottom of the casing 1, and it is difficult for the second outer side 45 to form a coplanar or parallel structure with the front panel 81 of the casing 1, resulting in an irregular and unattractive overall appearance of the wall-mounted air conditioner 10.

[0139] By setting the included angle between the first outer side 35 and the second outer side 45 to 80° to 100°, the first outer side 35 can be located in the same plane or nearly in the same plane as the bottom of the casing 1, or the plane where the first outer side 35 is located is parallel to the plane where the bottom of the casing 1 is located. The second outer side 45 can be located in the same plane or nearly in the same plane as the panel 81 installed at the front of the casing 1, or the plane where the second outer side 45 is located is parallel to the plane where the panel 81 is located. This makes the overall appearance of the wall-mounted air conditioner 10 more regular and beautiful.

[0140] In some embodiments of this application, reference is made to Figures 1-4 , Figure 6 As shown, when the first air guide plate 3 and the second air guide plate 4 close the heat exchange outlet 15, the first outer side 35 is horizontally arranged, and the second outer side 45 is vertically arranged, with an angle of 90° between the first outer side 35 and the second outer side 45. The first outer side 35 can be located in the same plane as the bottom of the casing 1, and the plane of the second outer side 45 is parallel to the plane of the front panel 81 installed on the casing 1, making the overall appearance of the wall-mounted air conditioner 10 more regular and beautiful.

[0141] Reference Figures 3-4 , Figure 7 , Figures 9-11 , Figure 14 As shown, the base 83 includes a mounting plate 832, on which a first mounting hole 8321 and a second mounting hole 8322 are provided. A first pivot shaft 51 passes through the first mounting hole 8321 to be supported by the base 83, and a second pivot shaft 52 passes through the second mounting hole 8322 to be supported by the base 83.

[0142] In some embodiments of this application, reference is made to Figure 3 , Figure 7 , Figures 9-10 , Figure 12 , Figure 16As shown, the heat exchange air inlet 14 is located at the top of the casing 1, and the heat exchange air outlet 15 is located at the lower front of the casing 1. This allows air to enter from the top and exit from the lower front, thus preventing the heat exchange air from being directly drawn into the heat exchange air inlet 14 after being blown out from the heat exchange air outlet 15, reducing the process of heat exchange air idling without participating in indoor heat exchange.

[0143] In addition, the heat exchange air inlet 14 is located on the top of the casing 1, that is, in an area that cannot be seen by the user. Hiding the heat exchange air inlet 14 can improve the aesthetic appearance of the wall-mounted air conditioner 10.

[0144] It is understandable that the side of the wall-mounted air conditioner 10 that is connected to the wall is usually called the back or rear side, while the side opposite to the rear side is called the front side. Therefore, when the heat exchange outlet 15 is located at the lower front of the casing 1, the air outlet is away from the wall, the air resistance is small, and the air delivery range is wide.

[0145] Wall-mounted air conditioners 10 are typically installed on walls. To avoid interfering with daily life, they are usually mounted high up. By designing the wall-mounted air conditioner 10 to blow heat exchange air from the front and bottom, the blown heat exchange air is less likely to be blocked by the ceiling or floor. This results in less resistance and energy loss during the airflow process, a wider air delivery range, and allows the heat exchange air to quickly circulate throughout the entire indoor space, improving heat exchange efficiency.
