The indoor part includes an air inlet hole at a bottom wall of the indoor part. The air inlet hole penetrates the chassis in a thickness direction of the indoor part.

Abstract: A mounting bracket includes a support frame extending in an inside-outside direction and including an outdoor part configured to be arranged outdoors, and a support leg configured to be arranged outdoors. An upper end of the support leg is connected to the outdoor part of the support frame and a lower end of the support leg is configured to directly or indirectly abut against an outer wall surface of a wall body. The outdoor part of the support frame includes a first limiting structure. The support leg includes a second limiting structure provided at the upper end of the support leg. The second limiting structure is in a limiting fit with the first limiting structure to limit a maximum included angle between the support leg and the support frame facing towards an indoor side so as to prevent a rotation angle of the support leg relative to the support frame in a direction facing away from the wall body from exceeding the maximum included angle.
