Description

Technical Field

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

[0002] Most existing wall-mounted air conditioners use a top-intake, bottom-out airflow design. Due to the characteristics of cold air being heavy and sinking easily, and hot air being light and rising easily, wall-mounted air conditioners are installed high up. The bottom-out airflow design makes it difficult to simultaneously achieve both cooling and heating comfort. Generally, a compromise solution can only be adopted.

[0003] A small number of wall-mounted air conditioners with top and bottom air outlets use different air delivery methods for cooling and heating, resulting in better air delivery comfort. However, they employ dual centrifugal fans or dual cross-flow fans. For example, one proposed dual cross-flow top and bottom air outlet air conditioner includes an upper cross-flow fan, an evaporator, and a lower cross-flow fan, arranged sequentially from top to bottom. This results in a relatively large casing size in the height direction, requiring more vertical space for installation, making it difficult to promote. Furthermore, when the air outlet is top-mounted, the airflow tends to blow onto the ceiling, hindering smooth airflow. Utility Model Content

[0004] The main objective of this invention is to provide a wall-mounted air conditioner to solve the problem that the casing of existing wall-mounted air conditioners with top and bottom air outlets has a large dimension in the height direction.

[0005] To achieve the above objectives, according to one aspect of the present invention, a wall-mounted air conditioner is provided, comprising: a housing, on which a connected air duct cavity and an evaporator mounting cavity are provided, the air duct cavity being located on the side of the evaporator mounting cavity away from the mounting wall surface of the wall-mounted air conditioner; an evaporator, disposed within the evaporator mounting cavity and spaced apart from the back shell plate of the housing; a partition, disposed within the air duct cavity, the front and rear ends of the partition contacting the housing and the evaporator respectively, to divide the air duct cavity into a first air duct and a second air duct, and connecting the first air duct and the second air duct through the evaporator mounting cavity; a first fan and a second fan, the first fan and the second fan being respectively disposed within the first air duct and the second air duct, both the first fan and the second fan being rotatable in both directions.

[0006] Furthermore, the partition includes an isolation body and a plug-in portion connected together. The isolation body is located on the side of the plug-in portion away from the evaporator and is connected to the housing. The evaporator is provided with a plug-in groove for plugging into the plug-in portion.

[0007] Furthermore, the portion of the isolation body near the insertion part is set at a first predetermined angle B with the insertion part, where the first predetermined angle B is an obtuse angle; wherein, the distance between the isolation body and the insertion part gradually increases from top to bottom; and / or the insertion part is a wedge-shaped protrusion, and the insertion groove is a wedge-shaped groove that engages with the wedge-shaped protrusion; and / or the first fan is a cross-flow fan, and the side of the isolation body near the first fan includes a first arc-shaped isolation surface corresponding to the outer contour of the first fan; and / or the second fan is a cross-flow fan, and the side of the isolation body near the second fan includes a second arc-shaped isolation surface corresponding to the outer contour of the second fan.

[0008] Furthermore, the insertion part and the evaporator are arranged at a second predetermined angle C, which is an obtuse angle; wherein, the distance between the insertion part and the evaporator gradually decreases from top to bottom.

[0009] Furthermore, the second predetermined included angle C ranges from 106° to 150°.

[0010] Furthermore, the distance L between the evaporator and the back shell is greater than or equal to 35 mm.

[0011] Furthermore, the first air duct includes a first air outlet and a second air outlet, the first air outlet being disposed on the housing and located on the front side of the housing, and the second air outlet being connected to the evaporator mounting cavity; and / or the second air duct includes a third air outlet and a fourth air outlet, the third air outlet being connected to the evaporator mounting cavity, and the fourth air outlet being disposed on the housing and located on the lower side of the housing.

[0012] Furthermore, a first air guide drive unit, a first support shaft, and a first air guide plate are disposed within a first air duct and located at a first air outlet. The first air guide drive unit, the first support shaft, and the first air guide plate are sequentially connected in a direction away from the evaporator mounting cavity. The first air guide drive unit drives the first air guide plate to move at the first air outlet via the first support shaft. And / or a second air guide drive unit, a second support shaft, and a second air guide plate are disposed within a second air duct and located at a fourth air outlet. The second air guide drive unit, the second support shaft, and the second air guide plate are sequentially connected in a direction away from the evaporator mounting cavity. The second air guide drive unit drives the second air guide plate to move at the fourth air outlet via the second support shaft.

[0013] Furthermore, the wall-mounted air conditioner also includes a water collection tray, which is located inside the casing and below the evaporator, with the lower part of the evaporator inserted into the water collection tray.

[0015] According to the technical solution of this utility model, the wall-mounted air conditioner includes: a housing, on which a connected air duct cavity and an evaporator mounting cavity are provided, the air duct cavity being located on the side of the evaporator mounting cavity away from the mounting wall surface of the wall-mounted air conditioner; an evaporator, which is disposed in the evaporator mounting cavity and spaced apart from the back shell plate of the housing; a partition, which is disposed in the air duct cavity, with its front and rear ends respectively contacting the housing and the evaporator to divide the air duct cavity into a first air duct and a second air duct, and connecting the first air duct and the second air duct through the evaporator mounting cavity; a first fan and a second fan, which are respectively disposed in the first air duct and the second air duct, and both the first fan and the second fan are rotatable in both directions. In this way, the wall-mounted air conditioner of this utility model, by setting up an air duct cavity, an evaporator mounting cavity, and a partition, divides the air duct cavity into a first air duct and a second air duct to install the first fan and the second fan respectively. The overall structure is compact, which solves the problem of the large size of the shell in the height direction of the existing wall-mounted air conditioners with top and bottom air outlets. It saves the installation size in the height direction, and makes the airflow entering the air duct cavity need to pass through the evaporator mounting cavity to exchange heat with the evaporator twice before flowing out of the wall-mounted air conditioner. This increases the heat exchange area between the airflow and the evaporator, and solves the problem of poor outlet air temperature caused by the airflow in the air conditioner only exchanging heat with the evaporator once in the existing technology. As a result, the outlet air temperature of the wall-mounted air conditioner is lower when cooling and higher when heating, which effectively improves the operation of the air conditioner, improves the heat exchange efficiency of the wall-mounted air conditioner, and improves user comfort. It is especially suitable for occasions with high requirements for air conditioning cooling and heating effects. In addition, the wall-mounted air conditioner of this utility model can achieve bidirectional reversible air intake and exhaust by controlling the rotation direction of the first fan and the second fan, making the air supply mode more flexible.

[0035] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 5As shown, this utility model provides a wall-mounted air conditioner, including: a housing 1, on which a connected air duct cavity 11 and an evaporator mounting cavity 12 are provided, the air duct cavity 11 being located on the side of the evaporator mounting cavity 12 away from the mounting wall surface of the wall-mounted air conditioner; an evaporator 2, disposed within the evaporator mounting cavity 12 and spaced apart from the back shell plate 13 of the housing 1; a partition 3, disposed within the air duct cavity 11, the front and rear ends of the partition 3 contacting the housing 1 and the evaporator 2 respectively, to divide the air duct cavity 11 into a first air duct 111 and a second air duct 112, and connecting the first air duct 111 and the second air duct 112 through the evaporator mounting cavity 12; a first fan 4 and a second fan 5, the first fan 4 and the second fan 5 being disposed within the first air duct 111 and the second air duct 112 respectively, both the first fan 4 and the second fan 5 being rotatable in both directions.

[0037] In this way, the wall-mounted air conditioner of this utility model, by setting up the air duct cavity 11, the evaporator mounting cavity 12, and the partition 3, divides the air duct cavity 11 into the first air duct 111 and the second air duct 112, so as to install the first fan 4 and the second fan 5 respectively. The overall structure is compact, which solves the problem of the large size of the shell in the height direction of the wall-mounted air conditioner with top and bottom air outlet in the prior art. It saves the installation size in the height direction, and makes the airflow entering the air duct cavity 11 need to pass through the evaporator mounting cavity 12 to exchange heat with the evaporator 2 twice before flowing out of the wall-mounted air conditioner. This increases the heat exchange area between the airflow and the evaporator 2, and solves the problem of poor outlet air temperature caused by the airflow in the air conditioner only exchanging heat with the evaporator once in the prior art. As a result, the outlet air temperature of the wall-mounted air conditioner is lower when cooling and higher when heating, which effectively improves the operation of the air conditioner, improves the heat exchange efficiency of the wall-mounted air conditioner, and improves user comfort. It is especially suitable for occasions with high requirements for air conditioning cooling and heating effects. In addition, the wall-mounted air conditioner of this utility model can achieve bidirectional reversible air intake and exhaust by controlling the rotation direction of the first fan 4 and the second fan 5, making the air supply mode more flexible. It can adjust the air supply direction according to user needs and environmental changes, meet the different needs of users for cooling and heating, and improve the comfort and applicability of the wall-mounted air conditioner.

[0038] Specifically, the back cover 13 is located on the side of the housing 1 near the mounting wall of the wall-mounted air conditioner and is in contact with the mounting wall. The front and rear ends of the partition 3 refer to the end of the partition 3 away from the mounting wall of the wall-mounted air conditioner and the end of the partition 3 near the mounting wall of the wall-mounted air conditioner. The first fan 4 and the second fan 5 can be set to rotate in both directions, which means that the first fan 4 and the second fan 5 can rotate both clockwise and counterclockwise. By changing the rotation direction of the first fan 4 and the second fan 5, bidirectional reversible air outlet of the first air duct 111 and the second air duct 112 can be achieved, such as air entering through the first air duct 111 and air exiting through the second air duct 112, or air exiting through the first air duct 111 and air entering through the second air duct 112.

[0039] like Figures 1 to 5 As shown, the partition 3 includes an isolation body 31 and a plug-in part 32 connected to each other. The isolation body 31 is located on the side of the plug-in part 32 away from the evaporator 2 and is connected to the housing 1. The evaporator 2 is provided with a plug-in groove 21 for plugging and engaging with the plug-in part 32.

[0040] In the wall-mounted air conditioner of this utility model, the partition 3 and the evaporator 2 are connected by the insertion part 32 and the insertion slot 21, so as to achieve a stable connection between the partition 3 and the evaporator 2 and ensure a stable separation between the first air duct 111 and the second air duct 112.

[0041] like Figures 1 to 5 As shown, the portion of the isolation body 31 near the insertion part 32 is set at a first predetermined angle B with the insertion part 32, where the first predetermined angle B is an obtuse angle; wherein, the distance between the isolation body 31 and the insertion part 32 gradually increases from top to bottom; and / or the insertion part 32 is a wedge-shaped protrusion, and the insertion groove 21 is a wedge-shaped groove that engages with the wedge-shaped protrusion; and / or the first fan 4 is a cross-flow fan, and the side of the isolation body 31 near the first fan 4 includes a first arc-shaped isolation surface 311 corresponding to the outer contour of the first fan 4; and / or the second fan 5 is a cross-flow fan, and the side of the isolation body 31 near the second fan 5 includes a second arc-shaped isolation surface 312 corresponding to the outer contour of the second fan 5.

[0042] The partition 3 of this utility model optimizes the airflow path in the wall-mounted air conditioner by setting a first predetermined angle B between the isolation body 31 and the plug-in part 32, thereby improving the airflow efficiency in the wall-mounted air conditioner, making the heat exchange effect of the wall-mounted air conditioner better, and improving the operating efficiency and safety of the air conditioner.

[0043] The wedge-shaped fit structure between the insertion part 32 of the partition 3 and the insertion groove 21 of the evaporator 2 further ensures the stable connection between the partition 3 and the evaporator 2, and can divide the evaporator 2 into upper and lower parts. The airflow entering one of the first air duct 111 and the second air duct 112 will flow through the two parts of the evaporator 2 in sequence, and then enter the other of the first air duct 111 and the second air duct 112, and finally be discharged to the outside of the wall-mounted air conditioner, so that the heat exchange effect of the evaporator 2 is more complete and the outlet air temperature of the wall-mounted air conditioner is better.

[0044] The first arc-shaped isolation surface 311 and the second arc-shaped isolation surface 312 on the isolation body 31 of the partition 3 of this utility model guide the airflow in the first air duct 111 and the second air duct 112, further optimize the airflow path in the wall-mounted air conditioner, improve the air circulation efficiency in the wall-mounted air conditioner, and enhance the heat exchange effect of the wall-mounted air conditioner.

[0045] like Figure 2 As shown, the insertion part 32 and the evaporator 2 are arranged at a second predetermined angle C, which is an obtuse angle; wherein, the distance between the insertion part 32 and the evaporator 2 gradually decreases from top to bottom.

[0046] The partition 3 of this utility model optimizes the flow path of condensate by adjusting the angle between the plug part 32 and the evaporator 2, so that the condensate can flow along the evaporator 2 into the water receiving tank 6 below it, avoiding the condensate from flowing into the first air duct 111 or the second air duct 112 and causing water leakage, thereby improving the operating efficiency and safety of the air conditioner.

[0047] like Figures 1 to 5 As shown, the second predetermined included angle C ranges from 106° to 150°.

[0048] The partition 3 of this utility model, by setting a specific range of the angle between the plug-in part 32 and the evaporator 2, effectively avoids condensate from flowing into the first air duct 111 or the second air duct 112 and causing water leakage, thereby improving the operating efficiency and safety of the air conditioner.

[0049] like Figure 1 As shown, the distance L between the evaporator 2 and the back shell plate 13 is greater than or equal to 35 mm.

[0050] This invention ensures good air circulation within the wall-mounted air conditioner by adjusting the distance between the evaporator 2 and the back cover plate 13, further optimizing the airflow path and improving the air circulation efficiency, resulting in better heat exchange performance.

[0051] like Figure 1 as well as Figures 3 to 5As shown, the first air duct 111 includes a first air outlet 113 and a second air outlet. The first air outlet 113 is disposed on the housing 1 and located on the front side of the housing 1, and the second air outlet is connected to the evaporator mounting cavity 12; and / or the second air duct 112 includes a third air outlet and a fourth air outlet 114. The third air outlet is connected to the evaporator mounting cavity 12, and the fourth air outlet 114 is disposed on the housing 1 and located on the lower side of the housing 1.

[0052] Specifically, the front side of housing 1 refers to the side of housing 1 away from the mounting wall of the wall-mounted air conditioner, and the lower side of housing 1 refers to the side of housing 1 close to the indoor floor.

[0053] The wall-mounted air conditioner of this utility model includes two air supply modes: bottom air intake and front air outlet, and front air intake and bottom air outlet. When the wall-mounted air conditioner is in the bottom air intake and front air outlet mode, the outside air of the wall-mounted air conditioner is first drawn into the second air duct 112 by the second fan 5 through the fourth air outlet 114, and then passes through the third air outlet, the lower and upper parts of the evaporator 2, and the second air outlet before reaching the first air duct 111. Finally, it is sent out to the outside of the wall-mounted air conditioner by the first fan 4 through the first air outlet 113. When the wall-mounted air conditioner is in the front air intake and bottom air outlet mode, the outside air of the wall-mounted air conditioner is first drawn into the first air duct 111 by the first fan 4 through the first air outlet 113, and then passes through the second air outlet, the upper and lower parts of the evaporator 2, and the third air outlet before reaching the second air duct 112. Finally, it is sent out to the outside of the wall-mounted air conditioner by the second fan 5 through the fourth air outlet 114.

[0054] This invention, by setting the first air outlet 113 of the first air duct 111 on the housing 1 and located on the front side of the housing 1, and setting the fourth air outlet 114 of the second air duct 112 on the housing 1 and located on the lower side of the housing 1, avoids the cold airflow blowing directly onto the ceiling 102 when the air is discharged through the first air outlet 113. It eliminates the need to reserve airflow space at the top of the wall-mounted air conditioner, making the required installation height of the wall-mounted air conditioner smaller, and allowing the wall-mounted air conditioner to be installed close to the ceiling 102. Especially in the cooling mode with bottom air intake and front air outlet, the blowing height of the cold airflow from the first air outlet 113 can avoid people and will not blow directly onto the ceiling 102, effectively reaching the lower part of the room to achieve rapid cooling of the room, improve the comfort of use, and provide users with a more energy-saving, efficient and beautiful home appliance solution.

[0055] This invention sets the fourth air outlet 114 of the second air duct 112 on the housing 1 and on the lower side of the housing 1, so that when the air is blown out from the fourth air outlet 114 in the heating mode, the hot airflow can settle smoothly and land vertically, and the heat can be evenly distributed, thereby greatly improving the coverage and absorption effect of the hot air.

[0056] like Figure 5 As shown, the wall-mounted air conditioner of this utility model is installed on the wall 101 and is set close to the ceiling 102. The wall surface on which the wall-mounted air conditioner is installed is the surface of the wall 101.

[0057] like Figure 1 as well as Figures 3 to 5 As shown, a first air guide drive unit 81, a first support shaft 82, and a first air guide plate 83 are arranged in the first air duct 111 and located at the first air outlet 113. The first air guide drive unit 81, the first support shaft 82, and the first air guide plate 83 are sequentially connected in a direction away from the evaporator mounting cavity 12. The first air guide drive unit 81 drives the first air guide plate 83 to move at the first air outlet 113 through the first support shaft 82. And / or a second air guide drive unit 91, a second support shaft 92, and a second air guide plate 93 are arranged in the second air duct 112 and located at the fourth air outlet 114. The second air guide drive unit 91, the second support shaft 92, and the second air guide plate 93 are sequentially connected in a direction away from the evaporator mounting cavity 12. The second air guide drive unit 91 drives the second air guide plate 93 to move at the fourth air outlet 114 through the second support shaft 92.

[0058] The wall-mounted air conditioner of this utility model achieves precise control over the opening degree of the first air outlet 113 and the fourth air outlet 114 by setting a first air guide drive unit 81, a first bracket shaft 82 and a first air guide plate 83, as well as a second air guide drive unit 91, a second bracket shaft 92 and a second air guide plate 93, thereby meeting the different needs of users for air supply size and air supply direction, and improving the comfort and flexibility of the air conditioner.

[0059] like Figure 1 as well as Figures 3 to 5 As shown, the wall-mounted air conditioner also includes a water collection tank 6, which is located inside the housing 1 and below the evaporator 2. The lower part of the evaporator 2 is inserted into the water collection tank 6.

[0060] The wall-mounted air conditioner of this utility model has a water collection tank 6, which catches the condensate flowing down from the evaporator 2, effectively collecting the condensate and preventing it from dripping directly onto other parts of the wall-mounted air conditioner, thus improving the safety of using the wall-mounted air conditioner.

[0061] like Figure 1 as well as Figures 3 to 5 As shown, the height H of the portion of the evaporator 2 inserted into the water receiving tank 6 is greater than or equal to 10 mm; and / or the opening of the water receiving tank 6 is funnel-shaped; and / or the wall-mounted air conditioner also includes a layer of insulation material 7 covering the outside of the water receiving tank 6.

[0062] The wall-mounted air conditioner of this invention has the lower end of the evaporator 2 inserted into the water collection tank 6 at a depth of at least 10mm, which enhances the collection efficiency of the water collection tank 6 for condensate. This ensures that the condensate generated during the operation of the wall-mounted air conditioner can be quickly and completely collected into the water collection tank 6, effectively preventing condensate from overflowing or dripping to the outside of the water collection tank 6. This maintains the cleanliness and dryness of other parts of the wall-mounted air conditioner and the indoor environment, and improves the user experience.

[0063] The wall-mounted air conditioner of this utility model has an insulation material layer 7 outside the water receiving tank 6, which further improves the collection efficiency of condensate and prevents the generation of condensate outside the water receiving tank 6, thereby improving the safety of the wall-mounted air conditioner.

[0064] Optionally, the insulation layer 7 can be foam or sponge. Firstly, foam and sponge possess excellent thermal insulation properties, effectively reducing energy loss and maintaining a stable ambient temperature around the water collection tank 6, preventing condensation and thus protecting the internal components of the wall-mounted air conditioner from humidity, extending its lifespan. Secondly, these two materials are lightweight and easy to install, reducing the overall burden on the wall-mounted air conditioner and simplifying the manufacturing process, thus lowering production costs. Thirdly, foam or sponge has good flexibility and compression resilience, allowing it to closely conform to surfaces of various shapes, maintaining good sealing even under vibration or external forces, ensuring effective collection of condensate without leakage, improving the safety and user experience of the wall-mounted air conditioner. Finally, the porous structure of foam and sponge helps to reduce noise, creating a quieter and more comfortable environment, especially important at night when resting, providing users with a more tranquil living space.

[0065] like Figure 6 As shown, the control method of the wall-mounted air conditioner of this utility model includes:

[0066] Step S1: Turn on the wall-mounted air conditioner and turn on the heating mode;

[0067] Step S2: Control the first air guide plate 83 and the second air guide plate 93 to move to their respective predetermined positions according to their respective motion trajectories, so as to open the first air vent 113 and the fourth air vent 114 respectively;

[0068] Step S3: When the second air guide plate 93 moves past half of the predetermined trajectory, control the first fan 4 to rotate clockwise at the first speed N1 (where N1 = 500 rpm to 650 rpm), and control the second fan 5 to rotate clockwise at the second speed N1-200 rpm, so that the wall-mounted air conditioner operates in the manner of bottom air intake and front air exhaust.

[0069] Step S4: Control the wall-mounted air conditioner to run in a bottom air intake and front air outlet mode for two minutes to avoid the initial unheated cold air blowing directly on the user;

[0070] Step S5: Control the second fan 5 to rotate counterclockwise at the third speed N2 (where N2≥1100rpm), control the first fan 4 to rotate counterclockwise at the fourth speed N2-700rpm, and control the second air guide plate 93 to reciprocate within the preset angle range so that the wall-mounted air conditioner operates in the manner of front airflow and bottom airflow.

[0071] Step S6: Control the wall-mounted air conditioner to continue operating in a forward-flowing, downward-flowing mode so that the hot airflow blows directly to the ground.

[0072] Specifically, when a wall-mounted air conditioner is first turned on in winter and the heating mode is activated, the air outlet temperature has not yet risen. If it is operated directly in the forward-in, downward-out mode, the initially unheated cold air will blow directly onto the user, which may cause discomfort. Therefore, the wall-mounted air conditioner needs to operate in the downward-in, forward-out mode first to avoid the cold air blowing directly onto the user. After the wall-mounted air conditioner has been running for two minutes, the air outlet temperature has risen. At this time, the wall-mounted air conditioner operates in the forward-in, downward-out mode so that the hot air blows directly to the ground, warming the user's entire body. In addition, the reciprocating motion of the second air guide plate 93 within the preset angle range can make the delivered hot air evenly cover the entire room, allowing the user to feel all-round warmth and comfort, rather than localized heating in one direction.

[0073] In this way, the wall-mounted air conditioner of this utility model not only solves the discomfort problem that may be caused by the wall-mounted air conditioner in the early stage of winter operation, but also improves the overall air supply efficiency and user experience, ensuring that the ideal heating effect can be achieved quickly in any environment, so that warmth can be found everywhere.

[0074] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0075] The wall-mounted air conditioner of this utility model includes: a housing 1, on which a connected air duct cavity 11 and an evaporator mounting cavity 12 are provided, the air duct cavity 11 being located on the side of the evaporator mounting cavity 12 away from the mounting wall surface of the wall-mounted air conditioner; an evaporator 2, which is disposed in the evaporator mounting cavity 12 and spaced apart from the back shell plate 13 of the housing 1; a partition 3, which is disposed in the air duct cavity 11, with its front and rear ends respectively contacting the housing 1 and the evaporator 2 to divide the air duct cavity 11 into a first air duct 111 and a second air duct 112, and connecting the first air duct 111 and the second air duct 112 through the evaporator mounting cavity 12; a first fan 4 and a second fan 5, which are respectively disposed in the first air duct 111 and the second air duct 112, and both the first fan 4 and the second fan 5 can be rotatably arranged in both directions. In this way, the wall-mounted air conditioner of this utility model, by setting up the air duct cavity 11, the evaporator mounting cavity 12, and the partition 3, divides the air duct cavity 11 into the first air duct 111 and the second air duct 112, so as to install the first fan 4 and the second fan 5 respectively. The overall structure is compact, which solves the problem of the large size of the shell in the height direction of the wall-mounted air conditioner with top and bottom air outlet in the prior art. It saves the installation size in the height direction, and makes the airflow entering the air duct cavity 11 need to pass through the evaporator mounting cavity 12 to exchange heat with the evaporator 2 twice before flowing out of the wall-mounted air conditioner. This increases the heat exchange area between the airflow and the evaporator 2, and solves the problem of poor outlet air temperature caused by the airflow in the air conditioner only exchanging heat with the evaporator once in the prior art. As a result, the outlet air temperature of the wall-mounted air conditioner is lower when cooling and higher when heating, which effectively improves the operation of the air conditioner, improves the heat exchange efficiency of the wall-mounted air conditioner, and improves user comfort. It is especially suitable for occasions with high requirements for air conditioning cooling and heating effects. In addition, the wall-mounted air conditioner of this utility model can achieve bidirectional reversible air intake and exhaust by controlling the rotation direction of the first fan 4 and the second fan 5, making the air supply mode more flexible. It can adjust the air supply direction according to user needs and environmental changes, meet the different needs of users for cooling and heating, and improve the comfort and applicability of the wall-mounted air conditioner.
