The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", etc. are used in an orientation or positional relationship based on that shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The first embodiment is as follows:

fig. 1 is an exploded view of a first perspective of the air conditioner rear case assembly of this embodiment, and fig. 2 is an exploded view of a second perspective of the air conditioner rear case assembly of this embodiment, as shown in fig. 1 and fig. 2, the rear case assembly includes a rear case body 1, the rear case body 1 is provided with a grill area 10 and a non-grill area, and the grill area 10 includes a plurality of grill holes.

Fig. 1 shows an inner side surface of the rear case body 1, and fig. 2 shows an outer side surface of the rear case body 1.

In the present example, the grill area 10 extends in a first horizontal direction of the rear case body 1, which in the present embodiment refers to a longitudinal direction (left-right direction in fig. 1) of the rear case body 1. The rear case body 1 is not limited to extend along a straight line or extend along a curved line, and in the present embodiment, the rear case body 1 extends along a curved line, thereby providing the grill area 10 with a curved surface structure. The curved structure of the grill area 10 has a large open angle range, and can absorb more air.

Further, the grid holes are not limited to rectangular, square, circular, and in the present embodiment, the grid holes include rectangular holes of various sizes.

The rear shell body 1 is provided with the grid area 10, the grid area 10 is provided with the grid holes, so that the grid holes are directly formed in the rear shell body 1, disassembly and assembly are not needed, and assembly gaps do not exist.

This backshell subassembly still includes filter screen 2, and filter screen 2 sets up in the inboard of grid region 10, and filter screen 2 can fix the inboard at grid region 10 with bolted connection's direction, and external space filters through filter screen 2 behind the grid hole.

It should be noted that the filter screen 2 may be configured as a whole mesh structure, or may be configured as a partitioned mesh structure corresponding to the grid holes. For example, the grille area 10 is provided with rectangular holes of different sizes, and after the filter screen 2 is installed in the grille area 10, the filter area of the filter screen 2 faces each rectangular hole in the thickness direction, that is, the filter screen 2 further includes a non-filter area (e.g., a bracket) which is not directly facing the grille hole. Thereby saving the manufacturing cost of the filter screen 2 and avoiding waste.

Example two:
