[0046] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0047] The following refers to Figures 1 - 15 a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention, which can be used for cooling and heating indoor air.

[0048] As Figures 1 - 8 、 Figure 15 shown, the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention includes: a housing 10, a front air deflector 20, an indoor heat exchanger 50, a main indoor fan 60, and a side indoor fan 40.

[0049] As Figure 1 、 Figure 3 、 Figure 5 and Figure 7As shown, the cabinet 10 may include a front frame 110 and a panel 120. The panel 120 is movably provided on the front frame 110 in the up-down direction. A main air flow channel 130 and two side air flow channels 140 may be provided inside the front frame 110. A front air outlet 110A communicating with the main air flow channel 130 may be provided at the front of the front frame 110. Side ventilation holes communicating with the corresponding side air flow channels 140 may be respectively provided on the left and right sides of the front frame 110. The panel 120 moves upward to expose the front air outlet 110A.

[0050] Specifically, when the wall-mounted air conditioner indoor unit 100 operates, the panel 120 can be controlled to move upward to open the front air outlet 110A. The air flow in the main air flow channel 130 can be discharged through the front air outlet 110A, and the air flows in the two side air flow channels 140 can be discharged through the corresponding side ventilation holes. When the wall-mounted air conditioner indoor unit 100 stops operating, the panel 120 can be controlled to move downward to close the front air outlet 110A. Thereby, the overall structure of the wall-mounted air conditioner indoor unit 100 can be made more coordinated, and dirt in the indoor air can be prevented from entering the cabinet 10 through the front air outlet 110A, which can play a role in protecting the wall-mounted air conditioner indoor unit 100. Optionally, a sliding groove (not shown in the figure) can be provided on the front frame 110. The panel 120 can cooperate with the sliding groove and can slide relative to the sliding groove. Thereby, the matching structure of the front frame 110 and the panel 120 can be made simpler and more convenient to operate.

[0051] As Figure 2 、 Figure 4 and Figure 6 shown, a plurality of first ventilation holes 120A may be provided on the panel 120. In the windless feeling mode, the panel 120 blocks at least a part of the front air outlet 110A and the plurality of first ventilation holes 120A are located on the front side of the front air outlet 110A. Specifically, the wall-mounted air conditioner indoor unit 100 has a normal air outlet mode and a first windless feeling mode. When the wall-mounted air conditioner indoor unit 100 is in the normal air outlet mode, the front frame 110 moves upward to partially or fully open the front air outlet 110A, and the air flow can blow to the front and the left and right sides of the wall-mounted air conditioner indoor unit 100 through the front air outlet 110A and the side ventilation holes on the left and right sides. It can be understood that the front air outlet 110A of the wall-mounted air conditioner indoor unit 100 can extend in the width direction of the cabinet 10, and the air outlet area of the front air outlet 110A is relatively large. Therefore, the air supply speed of the wall-mounted air conditioner indoor unit 100 in the normal air outlet mode is the fastest, and the cooling and heating efficiency is the highest.

[0052] When the wall-mounted air conditioner indoor unit 100 is in the first windless feeling mode, the panel 120 moves downward to completely or partially close the front air outlet 110A. At this time, a plurality of first ventilation holes 120A are located in front of the front air outlet 110A, and the air flow can enter the indoor space through the plurality of first ventilation holes 120A. Since the plurality of first ventilation holes 120A can be arranged at intervals, and the diameters of the plurality of first ventilation holes 120A are small, when the air flow passes through the plurality of first ventilation holes 120A, the plurality of first ventilation holes 120A can play a role in reducing the air flow velocity. When the air flow flows out from the plurality of first ventilation holes 120A, the air flow velocity is significantly reduced, thereby achieving the windless feeling effect and improving the user's comfort level.

[0053] For example, when the wall-mounted air conditioner indoor unit 100 is performing refrigeration work, since the cold air has a relatively large density and a relatively fast flow velocity, the wall-mounted air conditioner indoor unit 100 can be adjusted to the windless feeling mode. The air flow passing through the plurality of first ventilation holes 120A can slowly flow in the indoor space from top to bottom by relying on its own gravity, thereby making the indoor temperature distribution more uniform and achieving a better refrigeration effect. When the wall-mounted air conditioner indoor unit 100 is performing heating work, since the hot air has a relatively small density and a relatively slow flow velocity, the wall-mounted air conditioner indoor unit 100 can be adjusted to the normal air outlet mode, and the panel 120 moves upward to partially open or completely open the front air outlet 110A. Thus, the air supply speed of the wall-mounted air conditioner indoor unit 100 can be ensured, and its heating efficiency can be improved.

[0054] As Figures 4 - 5 shown, the front air deflector 20 is rotatably provided at the front air outlet 110A. Specifically, the rotation angle of the front air deflector 20 is adjustable, and the rotation angle of the front air deflector 20 can be selected according to the use requirements, and then the air supply area of the front air outlet 110A can be controlled. For example, when the wall-mounted air conditioner indoor unit 100 is performing refrigeration work, in order to prevent the cold air from directly blowing on the indoor users, after the panel 120 moves upward, the front air deflector 20 can be adjusted to rotate to completely close the front air outlet 110A. Thus, the cold air can be discharged through the side ventilation holes on the left and right sides and can slowly flow in the indoor space from top to bottom by relying on its own gravity, thereby not only making the indoor temperature distribution more uniform, but also improving the user's comfort level. Optionally, the front air deflector 20 can be a metal part, thereby improving the structural strength of the front air deflector 20.

[0055] As Figure 3 and Figure 15As shown, the indoor heat exchanger 50 is provided in the front frame 110, and the indoor heat exchanger 50 can exchange heat with the air flow entering the casing 10. The main indoor fan 60 can be provided in the main air flow path 130, and the two side indoor fans 40 can be respectively provided in the two side air flow paths 140. The rotation directions of the two side indoor fans 40 are variable so that the side ventilation holes can be switched between the side air inlets 110C and the side air outlets 110B. When the side ventilation holes are the side air inlets 110C, the air flow flowing into the side air flow paths 140 collides with the air flow in the main air flow path 130 at a position adjacent to the front air outlet 110A. Specifically, the main indoor fan 60 can guide the air flow to circulate in the main air flow path 130, and the two side indoor fans 40 can guide the air flow to circulate in the corresponding side air flow paths 140, and the rotation directions of the two side indoor fans 40 can be changed. For example, when the two side indoor fans 40 rotate forward, the air flow in the casing 10 can be blown out from the side ventilation holes, and at this time, the side ventilation holes are the side air outlets 110B. When the two side indoor fans 40 rotate reversely, the indoor air can be guided into the casing 10 through the side ventilation holes, and at this time, the side ventilation holes are the side air inlets 110C.

[0056] The wall-mounted air conditioner indoor unit 100 further has a second draft-free mode. When the wall-mounted air conditioner indoor unit 100 is in the second draft-free mode, the two side indoor fans 40 rotate reversely, the side ventilation holes are the side air inlets 110C, and the front air deflector 20 is opened. At this time, the main indoor fan 60 can guide the heat-exchanged air flow to flow to the front air outlet 110A, and the two side indoor fans 40 can guide the indoor air flow to enter the side air flow paths 140 from the side air inlets 110C on the left and right sides at the same time. The two air flows collide at a position adjacent to the front air outlet 110A in the main air flow path 130. Thus, the two air flows entering from the side air inlets 110C can be mixed with the heat-exchanged air flow, which can make the temperature of the heat-exchanged air flow more suitable and prevent the air flow from being too cold / too hot to make the user feel uncomfortable. In addition, the two air flows entering from the side air inlets 110C can change the flow direction of the heat-exchanged air flow through collision, which can make the heat-exchanged air flow flow in multiple directions in the indoor space. Thus, it can prevent the cold air / hot air from directly blowing on the indoor users, and can achieve a better draft-free effect and improve the user's comfort.

[0057] It should be noted that the first windless mode and the second windless mode of the wall-mounted air conditioner indoor unit 100 can be selected separately or simultaneously, and can be set according to actual usage requirements. For example, when the cooling temperature of the wall-mounted air conditioner indoor unit 100 is relatively low, in order to prevent cold air from directly blowing on the user, the first windless mode and the second windless mode can be selected simultaneously. After the two airflows entering from the side air inlet 110C collide and mix with the airflows that have completed heat exchange, they then pass through a plurality of first ventilation holes 120A and enter the indoor space. Thereby, the temperature comfort of the airflows can be made higher, and the cold air can slowly diffuse in the indoor space, improving the user's comfort.

[0058] According to the wall-mounted air conditioner indoor unit 100 of the embodiment of the present invention, by providing a plurality of first ventilation holes 120A on the panel 120, the air supply speed of the wall-mounted air conditioner indoor unit 100 can be made more gentle, and a better windless effect can be achieved, thereby improving the user's comfort. By setting the rotation direction of the side indoor fan 40 to be variable, not only can the temperature of the airflows be made more suitable, but also the flow direction of the airflows can be changed, thereby making the temperature distribution in the room more uniform and improving the user's comfort.

[0059] As Figure 4 and Figure 6 shown, according to some embodiments of the present invention, a plurality of second ventilation holes 210 are provided on the front air deflector 20. In the windless mode, the front air deflector 20 and the panel 120 cooperate to block the front air outlet 110A, thereby achieving a better windless effect. In a specific example of the present invention, when the wall-mounted air conditioner indoor unit 100 is in the windless mode, the front air deflector 20 and the panel 120 can simultaneously block the front air outlet 110A. The airflows that have completed heat exchange need to pass through a plurality of first ventilation holes 120A and a plurality of second ventilation holes 210 simultaneously to enter the indoor space. The plurality of first ventilation holes 120A and the plurality of second ventilation holes 210 decelerate the airflows for a second time, thereby making the flow speed of the airflows more gentle and achieving a better windless effect. Optionally, in order to ensure the air supply efficiency of the wall-mounted air conditioner indoor unit 100, the front air deflector 20 or the panel 120 can be controlled to partially block the front air outlet 110A, thereby increasing the air outlet speed of the front air outlet 110A.

[0060] In another specific example of the present invention, when the wall-mounted air conditioner indoor unit 100 is in the no-wind-sensation mode, the front air deflector 20 can block the lower part of the front air outlet 110A, and the panel 120 can block the upper part of the front air outlet 110A. A part of the air flow that has completed heat exchange can pass through the plurality of first ventilation holes 120A and enter the indoor space, and a part of the air flow that has completed heat exchange can pass through the plurality of second ventilation holes 210 and enter the indoor space. Thus, a better no-wind-sensation effect can be achieved.

[0061] As Figures 4 - 7 shown, according to some embodiments of the present invention, the front air deflector 20 may include a first air deflector 20A and a second air deflector 20B. A plurality of second ventilation holes 210 may be provided on both the first air deflector 20A and the second air deflector 20B. The first air deflector 20A is located above the second air deflector 20B. The second air deflector 20B is rotatably provided on the bottom wall of the front frame 110. In the no-wind-sensation mode, the lower end of the first air deflector 20A cooperates with the upper end of the second air deflector 20B. Thus, the structure of the front air deflector 20 can be made simpler, and it is convenient to adjust the air outlet direction and air volume of the front air outlet 110A.

[0062] Specifically, the first air deflector 20A and the second air deflector 20B can rotate relative to the housing 10 respectively, whereby the air volume and air outlet direction of the front air outlet 110A can be adjusted. As Figure 5 shown, when the wall-mounted air conditioner indoor unit 100 is in the normal air outlet mode, the first air deflector 20A and the second air deflector 20B rotate to an angle parallel to the air flow direction in the main air flow channel 130 respectively. At this time, the air outlet area of the front air outlet 110A is the largest, and the air flow can directly blow into the indoor space through the front air outlet 110A. As Figure 7 shown, when the wall-mounted air conditioner indoor unit 100 is in the no-wind-sensation mode, the second air deflector 20B rotates so that its upper end cooperates with the lower end of the first air deflector 20A, whereby the front air outlet 110A can be completely closed, and the air flow can pass through the plurality of second ventilation holes 210 on the first air deflector 20A and the second air deflector 20B and enter the indoor space.

[0063] It can be understood that the air outlet direction of the front air outlet 110A can be adjusted by controlling the first air deflector 20A and the second air deflector 20B to rotate to different angles respectively. For example, when the wall-mounted air conditioner indoor unit 100 is performing refrigeration work, in order to prevent cold air from directly blowing on indoor users, the first air deflector 20A and the second air deflector 20B can be adjusted so that the front air outlet 110A blows obliquely upward. Thus, the low-temperature air flow can slowly circulate from top to bottom in the indoor space by relying on its own gravity, which can not only improve the no-wind-sensation effect, but also make the indoor temperature distribution more uniform.

[0064] As shown Figures 8 - 10 In some embodiments of the present invention, a plurality of side air guiding plates 30 may be provided at each side ventilation hole. Thus, the plurality of side air guiding plates 30 can disperse the air flow at the side air outlet 110B, avoiding the air flow flowing out from the side air outlet 110B from directly blowing towards the user, thereby improving the physical comfort of the air flow at the side air outlet 110B. Optionally, each side air guiding plate 30 may be a metal part, thereby improving the structural strength of the side air guiding plate 30.

[0065] In some embodiments of the present invention, the plurality of side air guiding plates 30 may be spaced apart in the up-down direction, thereby facilitating the control of the air outlet angle of the air flow. Of course, it can be understood that the distribution manner of the plurality of side air guiding plates 30 is not limited to this. For example, as shown Figures 8 - 10 In the figure, the plurality of side air guiding plates 30 may also be evenly spaced in the front-back direction.

[0066] In some embodiments of the present invention, the side air guiding plate 30 is rotatably provided at the side ventilation hole, thereby facilitating the adjustment of the air outlet direction and air volume of the side air outlet 110B. For example, as shown Figure 10 In the figure, the plurality of side air guiding plates 30 are evenly spaced in the front-back direction, and each side air guiding plate 30 can rotate relative to the side ventilation hole. The plurality of side air guiding plates 30 can change the air outlet direction and air volume of the side air outlet 110B by changing their own rotation angles. Among them, when the plurality of side air guiding plates 30 rotate to an angle perpendicular to the air flow direction in the side air flow channel 140, the side ventilation hole is completely closed, and when the plurality of side air guiding plates 30 rotate to an angle parallel to the air flow direction in the side air flow channel 140, the side ventilation hole is completely opened. It can be understood that, as shown Figure 9 In the figure, the side air guiding plate 30 can also be set to be fixed relative to the side ventilation hole, thereby enabling the side air outlet 110B to blow in one direction, which can meet the specific use requirements of the user. Optionally, the opening and closing and opening angles of each side air guiding plate 30 can be controlled separately, thereby improving the user's flexibility in use and enabling the wall-mounted air conditioner indoor unit 100 to meet a variety of use requirements.

[0067] As shown Figure 1As shown, according to some embodiments of the present invention, a microporous air guiding plate can be provided at each side ventilation hole, and a plurality of side micropores 310 can be provided on the microporous air guiding plate, thereby improving the draft-free effect of the wall-mounted air conditioner indoor unit 100. Specifically, when the wall-mounted air conditioner indoor unit 100 is in the draft-free mode, the microporous air guiding plate partially or completely closes the side ventilation holes. When the air flow flows out from the side air flow channel 140, the side micropores 310 on the microporous air guiding plate can reduce the flow rate of the air flow. When the air flow flows out from the side micropores 310, its flow rate is significantly reduced, thereby achieving the draft-free effect and improving the user's comfort.

[0068] As Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, each second ventilation hole 210 can be formed as a circular hole, thereby making the structure of the front air guiding plate 20 simpler and more aesthetic. Optionally, the diameters of each second ventilation hole 210 can be the same or different, and can be selected and set according to design requirements. It can be understood that the shape of the second ventilation hole 210 is not limited to this, and the second ventilation hole 210 can also be set as a rectangular hole, a polygonal hole, etc.

[0069] As Figures 11 - 14 As shown, according to some embodiments of the present invention, a plurality of mounting through holes 220 can be provided on the front air guiding plate 20, and a plurality of air guiding blades 220A can be provided in each mounting through hole 220. The inner ends of the plurality of air guiding blades 220A are connected to each other, and the space between adjacent air guiding blades 220A defines the second ventilation hole 210, thereby improving the draft-free effect of the wall-mounted air conditioner indoor unit 100. Specifically, a connecting column 240 can be provided in each mounting through hole 220, and the inner ends of the plurality of air guiding blades 220A are simultaneously connected to the connecting column 240, thereby improving the structural firmness of the front air guiding plate 20. Each air guiding blade 220A can be formed as an arc shape, and the plurality of air guiding blades 220A are arranged around the connecting column 240. Thus, the plurality of air guiding blades 220A can form a circular air outlet space. Since the extension angles of the arc surfaces of each air guiding blade 220A are different, when the air flow passes through the mounting through hole 220, the plurality of air guiding blades 220A can not only slow down the flow rate of the air flow, but also change the flow direction of the air flow. The air flow can slowly flow in multiple directions of the indoor space, thereby achieving a better draft-free effect. Optionally, the plurality of mounting through holes 220 can be evenly spaced in the left-right direction, thereby making the air supply at the front air outlet 110A more uniform. Optionally, as Figure 14 shown, the diameters of each mounting through hole 220 can also be different and can be selected and set according to usage requirements.

[0070] As Figures 12 - 14As shown, in some embodiments of the present invention, the plurality of second ventilation holes 210 may further include a plurality of ventilation micropores 230 distributed outside the mounting through-hole 220, thereby improving the air supply efficiency of the wall-mounted air conditioner indoor unit 100. Specifically, the plurality of ventilation micropores 230 can increase the air outlet area of the front air outlet 110A. When the wall-mounted air conditioner indoor unit 100 is operating, the air flow can simultaneously flow out through the plurality of ventilation micropores 230 and the space between two adjacent air guide vanes 220A. Thus, not only can the windless feeling effect be achieved, but also the air outlet area of the front air outlet 110A can be increased, the air supply speed can be increased, and the operating load of the wall-mounted air conditioner indoor unit 100 can be reduced.

[0071] As Figure 1 shown, according to some embodiments of the present invention, the panel 120 is moved upward to expose the side ventilation holes, thereby making the operation of the wall-mounted air conditioner indoor unit 100 more convenient. Specifically, when the panel 120 is moved upward, the front air outlet 110A and the side ventilation holes can be exposed simultaneously. When the panel 120 is moved downward, the front air outlet 110A and the side ventilation holes can be blocked simultaneously, thereby saving operation time. It can be understood that the opening and closing of the front air outlet 110A and the side ventilation holes can also be controlled separately. For example, the panel 120 may include a first panel and a second panel. The first panel can be moved up and down to open and close the front air outlet 110A, and the second panel can be moved up and down to open and close the side ventilation holes. The first panel and the second panel can be controlled separately, and the user can choose to control the movement of the first panel and the second panel according to actual needs to select to open the front air outlet 110A and / or the side ventilation holes.

[0072] The air conditioner according to an embodiment of the present invention includes the wall-mounted air conditioner indoor unit 100 according to the above embodiments of the present invention.

[0073] The air conditioner according to an embodiment of the present invention, by providing the above-mentioned wall-mounted air conditioner indoor unit 100, and the wall-mounted air conditioner indoor unit 100 is provided with a plurality of first ventilation holes 120A on the panel 120, can make the air supply speed of the wall-mounted air conditioner indoor unit 100 more gentle, can achieve a better windless feeling effect, and thus can improve the user's comfort. The rotation direction of the side indoor fan 40 in the wall-mounted air conditioner indoor unit 100 is variable, which can not only make the temperature of the air flow more suitable, but also change the flow direction of the air flow, thereby making the indoor temperature distribution more uniform and improving the user's comfort.

[0074] Next, refer to Figures 1 - 15 to describe in detail the wall-mounted air conditioner indoor unit 100 according to a specific embodiment of the present invention. The wall-mounted air conditioner indoor unit 100 can be used for refrigeration and heating of indoor air. It should be understood that the following description is only exemplary and not a specific limitation of the present invention.

[0075] As shown in Figures 1 - 8 、 Figure 15 shown, the wall-mounted air conditioner indoor unit 100 includes: a housing 10, a front air deflector 20, side air deflectors 30, an indoor heat exchanger 50, a main indoor fan 60, and side indoor fans 40. Among them, the housing 10 includes a front frame 110 and a panel 120. A plurality of first ventilation holes 120A are provided on the panel 120. The panel 120 is movably provided on the front frame 110 in the up and down direction. A main air flow path 130 and two side air flow paths 140 are provided inside the front frame 110. A front air outlet 110A communicating with the main air flow path 130 is provided at the front of the front frame 110. Side ventilation holes communicating with the corresponding side air flow paths 140 are respectively provided on the left and right sides of the front frame 110. The panel 120 moves upward to expose the front air outlet 110A.

[0076] As shown in Figures 4 - 7 shown, the front air deflector 20 includes a first air deflector 20A and a second air deflector 20B. The first air deflector 20A is located above the second air deflector 20B. Both the first air deflector 20A and the second air deflector 20B can rotate relative to the housing 10. As shown in Figures 11 - 15 shown, a plurality of mounting through holes 220 and a plurality of ventilation micro holes 230 distributed outside the mounting through holes 220 are provided on both the first air deflector 20A and the second air deflector 20B. A connecting column 240 and a plurality of air deflector blades 220A are provided in each mounting through hole 220. Each air deflector blade 220A is formed as an arc. The inner ends of the plurality of air deflector blades 220A are connected to the connecting column 240 and arranged around the connecting column 240. Thus, the plurality of air deflector blades 220A form a circular air outlet space.

[0077] As shown in Figures 8 - 10 shown, a plurality of side air deflectors 30 are provided at each side ventilation hole. The plurality of side air deflectors 30 are evenly spaced in the front and rear directions. Each side air deflector 30 can rotate relative to the side ventilation hole. The plurality of side air deflectors 30 can change the air outlet direction and air volume of the side air outlet 110B by changing their own rotation angles.

[0078] As shown in Figure 3 and Figure 15As shown, the indoor heat exchanger 50 is provided in the front frame 110, the main indoor fan 60 is provided in the main air flow path 130, and the two side indoor fans 40 are respectively provided in the two side air flow paths 140. The main indoor fan 60 is disposed opposite to the front air outlet 110A, and the two side indoor fans 40 are disposed opposite to the corresponding side ventilation holes. The rotation directions of the two side indoor fans 40 are variable so that the side ventilation holes can be switched between the side air inlets 110C and the side air outlets 110B. When the side ventilation holes are the side air inlets 110C, the air flow flowing into the side air flow path 140 collides with the air flow in the main air flow path 130 at a position adjacent to the front air outlet 110A.

[0079] Specifically, when the wall-mounted air conditioner indoor unit 100 performs a cooling operation, in order to prevent cold air from directly blowing on indoor users, the wall-mounted air conditioner indoor unit 100 is adjusted to the first draft-free mode and the second draft-free mode at the same time. The panel 120 moves downward so that a plurality of first ventilation holes 120A are located in front of the front air outlet 110A. The first air deflector 20A and the second air deflector 20B rotate simultaneously and the upper end of the second air deflector 20B cooperates with the lower end of the first air deflector 20A, and the first air deflector 20A and the second air deflector 20B completely block the front air outlet 110A. The two side indoor fans 40 rotate reversely, and the side ventilation holes are the side air inlets 110C. Thus, the two air flows entering from the side air inlets 110C collide and mix with the air flow that has completed heat exchange at a position adjacent to the front air outlet 110A in the main air flow path 130, and then pass through the plurality of first ventilation holes 120A and the plurality of second ventilation holes 210 to enter the indoor space. The cold air can be slowly blown in multiple directions in the indoor space and then slowly circulate in the indoor space in a top-down manner, so that a good draft-free effect can be achieved and the user's comfort can be improved.

[0080] When the wall-mounted air conditioner indoor unit 100 performs a heating operation, since the density of the hot air is small and the flow rate is relatively slow, the wall-mounted air conditioner indoor unit 100 is adjusted to the normal air outlet mode. The panel 120 moves upward to fully open the front air outlet 110A, and the first air deflector 20A and the second air deflector 20B rotate simultaneously to an angle parallel to the air flow direction in the main air flow path 130, and the front air outlet 110A is fully opened. The two side indoor fans 40 rotate forward, and the side ventilation holes are the side air outlets 110B. Thus, the hot air can enter the indoor space through the front air outlet 110A of the wall-mounted air conditioner indoor unit 100 and the side air outlets 110B on the left and right sides at the same time, thereby increasing the air supply efficiency of the wall-mounted air conditioner indoor unit 100 and shortening the adjustment time of the indoor temperature.
