For example, any one point of the curved segment 3226 is equidistant from the projected outer contour 41 of the wind wheel 40. The distance between any point of the arc segment 3226 and the projected outer contour 41 of the wind wheel 40 means: a minimum distance between any point of arcuate segment 3226 and any point of outer contour 41.

Optionally, the distance H2 between the arc segment 3226 and the projected outer contour 41 of the wind wheel 40 is greater than or equal to 4 mm and less than or equal to 9 mm.

As shown in fig. 1 and 2, in a vertical plane perpendicular to the length direction of the air duct 30, a sixth included angle θ 6 between the center line L1 of the air outlet duct 322 and the center line L2 of the air inlet duct 321 is greater than or equal to 10 degrees and less than or equal to 85 degrees. It is possible to prevent the flow direction of the air in the air duct 30 from being largely changed so as to reduce the flow resistance of the air and to make the air smoothly flow in the air duct 30, so as to further improve the cooling and heating effects of the wall-mounted air conditioner 1.

Optionally, the sixth included angle θ 6 is greater than or equal to 20 degrees and less than or equal to 80 degrees. Alternatively, the sixth angle θ 6 is 40 degrees or more and 75 degrees or less. Alternatively, the sixth angle θ 6 is equal to or greater than 60 degrees and equal to or less than 75 degrees. Alternatively, the sixth angle θ 6 is 70 degrees or more and 75 degrees or less. The air can flow more smoothly in the air duct 30, and the cooling and heating effects of the wall-mounted air conditioner 1 can be further improved.

Alternatively, sixth included angle θ 6 may be, for example, but not limited to, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 71 degrees, 72 degrees, 73 degrees, 74 degrees, 75 degrees, 76 degrees, 77 degrees, 78 degrees, 79 degrees, 80 degrees, or 85 degrees.

The inventor has also found that in the related art, as shown in fig. 4, the air inlet of the wall-mounted air conditioner 1 ' is provided at the top thereof, and the top of the wall-mounted air conditioner 1 ' must be spaced apart from the indoor ceiling by a large distance to form an air inlet space, so that the wall-mounted air conditioner 1 ' cannot be closely attached to the indoor ceiling. The heat exchanger 10 ' of the wall-mounted air conditioner 1 ' is disposed around the cross flow wind wheel 20 '. Specifically, a first part 11 'of the heat exchanger 10' in a general inverted V shape is located above the cross-flow wind wheel 20 ', and a second part 12' of the heat exchanger 10 'is located in front of the cross-flow wind wheel 20'.

A drip tray 30 ' is provided below the rear lower end 111 ' of the first portion 11 '. The drain pan 30 ' is vertically opposite to the rear lower end 111 ' of the first section 11 ', and the drain pan 30 ' is located between the rear lower end 111 ' of the first section 11 ' and the cross-flow fan 20 '. The inventor has recognized that the rear lower end 111 ' of the first portion 11 ' is shielded by the drip tray 30 ', and thus the rear lower end 111 ' of the first portion 11 ' does not substantially exchange heat with air, resulting in waste and reduced heat exchange efficiency.

The second portion 12 'defines an air inlet passage 50' with a front panel 40 'of the wall-mounted air conditioner 1'. However, the inventor has recognized that since most of the space of the wall-mounted air conditioner 1 ' in the front-rear direction is occupied by the heat exchanger 10 ', the cross-flow wind wheel 20 ' and the scroll casing 60 ', the air intake passage 50 ' is made narrower, that is, the flow rate of air flowing through the air intake passage 50 ' is made smaller, thereby making the heat exchange efficiency of the second section 12 ' low.

As shown in fig. 1 and 2, at least a portion of the air inlet 311 in this embodiment is located on the front surface 11 of the casing 10. The front face 11 of the casing 10 is a surface of the casing 10 that can be seen by a horizontal rearward line of sight, i.e., the surface of the casing 10 that can be seen by a horizontal rearward line of sight is the front face 11 of the casing 10. For example, when the eyes of the observer and the casing 10 are located at substantially the same level and the observer is located in front of the casing 10, the surface of the casing 10 that the observer can see is the front face 11 of the casing 10.

For example, the wall-mounted air conditioner 1 may be installed on a wall surface 2. The direction of keeping away from wall 2 along the horizontal direction is just before, and the direction of keeping away from wall 2 along the horizontal direction is just after.

At least a portion of the air inlet 311 of the wall-mounted air conditioner 1 according to the present invention is located at the front of the cabinet 10, so that ambient air (intake air) can enter the air duct 30 from the substantially front of the cabinet 10. For example, the air (intake air) in the environment may enter the air duct 30 from the front of the cabinet 10, may enter the air duct 30 from the front upper side of the cabinet 10, and may enter the air duct 30 from the front lower side of the cabinet 10. Further, air in the environment may enter the air duct 30 from at least two directions of the front, the front upper direction, and the front lower direction of the cabinet 10.

That is, air in the environment may not necessarily enter the air duct 30 from directly above the cabinet 10. This can greatly reduce or eliminate the distance between the wall-mounted air conditioner 1 and the indoor ceiling wall 3, and can improve the indoor space utilization, and particularly, for an indoor (room) with a low height, can effectively reduce or eliminate the sense of oppression of the indoor space.

Therefore, the wall-mounted air conditioner 1 according to the embodiment of the present invention has very low requirements for the installation space, and the installation space only needs to accommodate the lower wall-mounted air conditioner 1, so that it is not necessary to leave an air intake space above the wall-mounted air conditioner 1, and the application range of the wall-mounted air conditioner 1 can be expanded.

In some alternative embodiments, the portion of the air inlet 311 located on the front face is inclined obliquely upward toward the wall surface 2 (which may be understood as a mounting surface) with respect to the vertical plane. In this way, when the user stands on the indoor floor, the user cannot see the inside of the cabinet 10 (wall-mounted air conditioner 1) through the air inlet 311, and the internal structure of the cabinet 10 (wall-mounted air conditioner 1) is not exposed to the user, which can improve the visual comfort of the user. Moreover, in the top air intake scene, the top space is often limited and narrow, so that the air intake is limited due to the narrow top space. In the technical solution of the present application, at least a portion of the air inlet 311 is located on the front surface of the housing, so that the air entering the air duct 30 through the air inlet 311 can directly flow through the heat exchanger 20, so as to sufficiently exchange heat with the heat exchanger 20. That is, the air intake of the wall-mounted air conditioner 1 is not limited by the narrow space at the top, and the air is introduced from the front of the cabinet 10, so that the air intake can be effectively increased, the flow rate of the air flowing through the heat exchanger 20 can be remarkably increased, and the heat exchange efficiency of the heat exchanger 20 can be greatly improved.

In the present application, at least a portion of the air inlet 311 is located on the front surface of the casing 10, and there is no need to provide a heat exchanger in a substantially inverted V shape below the air inlet 311, that is, there is no need to provide a water pan having a width greater than or equal to that of the heat exchanger in a substantially inverted V shape at a lower end of the heat exchanger in a substantially inverted V shape, so as to avoid that a portion of the heat exchanger does not exchange heat with air substantially due to shielding of the water pan. At least a part of the air inlet 311 is located on the front side of the casing 10, so that the water pan 15 may not prevent the air flow from flowing to the heat exchanger, for example, the water pan 15 may not flow to the flow path of the heat exchanger 20, which may greatly improve the heat exchange efficiency of the heat exchanger 20. Optionally, a drip tray 15 is provided below the heat exchanger 20.
