[0040] Among them, the hanging rack 1 is used for fixing on the mounting surface 100 to be installed, and the orientation of the mounting surface 100 is forward, the hanging rack 1 is provided with a support part 11 protruding forward, the support part 11 and the hanging rack 1 are an integral piece. In the embodiment, the hanging rack 1 is a left and right extending vertical plate, and the two support parts 11 arranged in one left and one right are a group, there are two groups, and the two groups are arranged on the hanging rack 1 in the left and right directions. At the same time, the upper end surface of each support part 11 is a plane extending forward relative to the hanging rack 1. The upper end surfaces of the support parts 11 are at the same height.

[0041] The appliance main body 2 is located on the front side of the mounting surface 100, and has a rear side wall 21 facing the mounting surface 100, the rear side wall 21 is provided with a mounting hole 210 penetrating the wall thickness thereof, the mounting hole 210 has two, one left and one right, and each mounting hole 210 is used for allowing the two support parts of the corresponding group to pass forward to hang the appliance main body 2 on the support part 11.

[0042] The rotating arm 3 has two, the first end of each rotating arm 3 is rotationally connected between the two support parts of the corresponding group through the left and right extending rotating shaft 32, and the first end of each rotating arm 3 is folded to extend rearward to form a limiting flange 33, the extension length of the limiting flange 33 is less than the length of the rotating arm 3. The junction of the rotating arm 3 and the limiting flange 33 is provided with a reinforcing rib 34. The second end of each rotating arm 3 is a free end 31, and the rotating arm 3 has the following two states:

[0043] The free end 31 of the rotating arm 3 extends forward to the extended state, at this time, the rotating arm 3 passes through the mounting hole 210 on the appliance main body 2 together with the support part 11; the limiting flange 33 extends downward and is supported on the front side of the hanging rack 1; for details, see Figure 6 ;

[0044] The free end 31 of the rotating arm 3 is adjacent to or abuts the rear side wall 21 of the appliance main body 2 in the folded state, at this time, the limiting flange 33 extends forward, the free end 31 of the rotating arm 3 extends upward and is located above the rear side wall 21 of the appliance main body 2.
