The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The rear cabinet 100 of the air conditioner 200 and the air conditioner 200 according to the embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 2, an air conditioner 200 according to an embodiment of the present invention includes a rear cabinet 100 of the air conditioner 200 according to an embodiment of the present invention. As shown in fig. 3 to 12, the rear cabinet 100 of the air conditioner 200 according to the embodiment of the present invention includes a cabinet case 10, a connecting portion group 20, and a reinforcing portion 30.

Specifically, as shown in fig. 3-6, the cabinet 10 extends in the longitudinal direction, and the connecting portion group 20 includes a plurality of connecting portions 21, and the plurality of connecting portions 21 are spaced apart in the longitudinal direction. As shown in fig. 7 and 8, the cabinet 10 is provided with a connecting portion group 20 on at least one side in the lateral direction, and the connecting portion 21 protrudes from the inner side of the cabinet 10. The reinforcement 30 extends in the longitudinal direction, and the reinforcement 30 is connected at least with the connection portion group 20.

For example, in the example shown in fig. 7 and 8, the cabinet 10 is provided with the two connecting portion groups 20 on both sides in the lateral direction, the two reinforcing portions 30 are provided, and the two reinforcing portions 30 are connected to the two connecting portion groups 20, respectively. Thus, the two reinforcing parts 30 can be reinforced by both lateral sides of the cabinet 10, and the structural stability of the rear cabinet 100 is more excellent.

It should be noted that the present invention is not limited to the connection manner between the reinforcement portion 30 and the connection portion 21, and as shown in fig. 4 to 6, the reinforcement portion 30 may be connected to the connection portion 21 in a snap-fit manner, or the reinforcement portion 30 may be connected to the connection portion 21 by a fastening member. Moreover, each connecting portion 21 and the reinforcing portion 30 can be connected in one or more connection modes, and the connection modes of the connecting portions 21 and the reinforcing portion 30 can be the same or different, so that the requirement of reliable connection between the connecting portions 21 and the reinforcing portion 30 can be met.

The utility model discloses an in the embodiment, be connected with rib 30 along horizontal at least one side at case shell 10 through connecting portion group 20 to rib 30 is connected with a plurality of connecting portion 21, and every connecting portion 21 is littleer along fore-and-aft extension dimension, is favorable to reducing machining error, improves the cooperation effect of a plurality of connecting portions 21 and rib 30, and then makes rib 30 can improve the structural stability of case shell 10 as far as possible.

In addition, since the structures of the plurality of connection parts 21 are independent of each other, the structure of each connection part 21 can be designed more flexibly.
