Example 1:

as shown in fig. 3, the upper surface of the case 100 is formed as a shielding surface 121.

More specifically, as shown in fig. 6 and 7, the housing 100 has a top wall 120 without an air inlet, and an outer surface of the top wall 120 is formed as a shielding surface 121. Therefore, the outer surface of the top wall 120 can be directly used as the shielding surface 121 for shielding dust, and the dust shielding device has the advantages of simple structure and convenience in cleaning.

The surface of the protruding portion 112 protrudes relative to the surface of the recessed portion 111, so that the protruding portion 112 can be abutted against the wall body on the back side of the product or other objects to ensure that the air inlet 101 at the position of the recessed portion 111 is effectively evacuated, thereby ensuring that the space is effectively kept between the air inlet 101 and the wall body on the back side of the product or other objects, avoiding the shielding of the air inlet 101, and ensuring the air inlet efficiency and uniformity of the air inlet 101.

For example, as shown in fig. 8, the housing 100 includes a face frame 100B and a chassis 100A, a back surface 110 of the chassis 100A (the back surface 110 of the chassis 100A may be understood as a rear-facing surface of the chassis 100A) is formed as the back surface 110 of the housing 100, or the back surface 110 of the chassis 100A and the back surface 110 of the housing 100 are the same feature. A groove is formed in a part of the back surface 110 of the chassis 100A, and the groove is used as the recess 111, wherein the groove has an opening, a bottom wall opposite to the opening, and a side wall extending from an edge of the bottom wall toward the opening (rearward). As shown in fig. 2, the air inlet 101 is formed in the bottom wall of the recess. Of course, in other embodiments, it is also contemplated that a portion of the intake vent 101 may be formed on the bottom wall of the recess and another portion may be formed on the side wall of the recess.

Example 4:

as shown in fig. 8, in addition to the features of embodiment 3 described above, there are further defined: the opposite sides of the recess 111 are respectively provided with a protrusion 112. Therefore, the back surface 110 of the wall-mounted air conditioner forms a triangular structure with a concave middle part and convex two sides, and when the air inlet 101 is effectively kept away to prevent the air inlet 101 from being shielded, the wall-mounted air conditioner enables the wall-mounted air conditioner to be more stable in installation or close to the wall and not easy to incline.

For example, as shown in fig. 2 and 8, the protruding portions 112 are respectively disposed on the left and right sides of the recessed portion 111, so that when the housing 100 is connected to a wall, the protruding portions 112 on the two sides of the recessed portion 111 can respectively form a space-avoiding supporting function, thereby not only ensuring a space-avoiding effect on the air inlet 101 at the recessed portion 111, but also ensuring the assembly stability of the wall-mounted air conditioner, and preventing the wall-mounted air conditioner from being inclined or swaying.
