As shown in fig. 1 to 8, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a cabinet 10, and the cabinet 10 includes a frame (not shown), a casing 100, and a panel 200.

The frame, the casing 100 and the panel 200 are constituent parts of the casing 10 of the indoor unit. The framework and the housing 100 form a structural main body of the casing 10, the housing 100 is mounted on the front side of the framework and fixed by adopting screws, and can be matched with a clamping structure for clamping, so that the framework and the housing 100 define an accommodating space of the casing 10 to accommodate components such as a fan, an indoor heat exchanger and the like. The enclosure 100 and the framework also define an air duct having an air inlet 11 and an air outlet 12. The panel 200 is covered on the front side of the casing 100 to constitute the front appearance of the wall-mounted air conditioner indoor unit, as shown in fig. 1. The panel 200 and the cover 100 may be connected by a plurality of engagement structures.

As shown in fig. 2, the top of the housing 100 is a grid plate portion 101, in other words, the grid plate portion 101 constitutes the top wall of the housing 100. The grill plate portion 101 has a plurality of air intake grilles 1101, and the plurality of air intake grilles 1101 constitute the air intake 11 of the cabinet 10. The housing 100 is an integrally formed unitary piece and the grid plate portion 101 is a portion of the housing 100. The housing 100 may be integrally injection molded.

As shown in fig. 5 and 6, the grid plate portion 101 has a rear edge strip 110 constituting a rear edge thereof. The rear bead 110 is elongated extending in the lateral direction (x-direction) of the housing 100, and the rear of the rear bead 110 no longer has a solid structure of the grid plate portion 101. In the embodiment of the present utility model, the front edge of the rear edge strip 110 constituting the rear edge of the grid plate portion 101 is bent downward to form the first flange 111 to enhance the strength of the rear edge strip 110.

The inventors found that the rear edge strips 110 of the grid plate portion 101 are heavy in load, and the stress concentration is the site where the risk of cracking is greatest. Therefore, in the embodiment of the utility model, the front edge of the rear edge strip 110 is bent downwards to form the first flanging 111, so that the strength of the rear edge strip 110 is enhanced, and the deformation resistance and the fracture resistance of the rear edge strip are improved. In the transportation process of the indoor unit of the wall-mounted air conditioner, the indoor unit of the wall-mounted air conditioner cannot crack.

Further, as shown in fig. 5, the grid plate portion 101 further includes a plurality of transverse grid bars 120 and a plurality of longitudinal grid bars 130. A plurality of transverse grid bars 120 are positioned in front of the rear edge bars 110 and are arranged front to back. The rear edge strip 110 may be considered a special, rearmost transverse grating strip 120. Each of the transverse grid bars 120 is an elongated bar extending in the transverse direction (x-direction) of the housing 100. A plurality of longitudinal grid bars 130 are arranged in the lateral direction of the housing, each longitudinal grid bar 130 extending in the front-rear direction. The plurality of transverse grid bars 120 and the plurality of longitudinal grid bars 130 are arranged crosswise to define a plurality of square shaped air inlet grids 1101. Since the rear side bar 110 serves as a carrying body, the width of the rear side bar 110 is preferably made wider than each of the lateral grille bars 120.

In some embodiments, referring to fig. 6 and 8, the first flange 111 may extend obliquely from top to bottom forward. The lower edge of the first flange 111 may be bent back to form a second flange 112, and the second flange 112 further reinforces the strength of the rear edge strip 110. The thickness of the second flange 112 is smaller than the thickness of the first flange 111.

Specifically, the ratio of the thickness of the first flange 111 to the thickness of the second flange 112 may be made to be between 3 and 4, inclusive. The length of the second turn-up 112 may be smaller than the length of the first turn-up 111. The embodiment of the utility model further enhances the strength by carrying out the special design on the details of the structural dimensional relationship, the extending direction and the like of the first flanging 111 and the second flanging 112.

In some embodiments, referring to fig. 3 and 4, a plurality of ribs 116 may be formed between the first flange 111 and the lower surface of the rear edge strip 110, and the plurality of ribs 116 may be arranged at intervals along the length direction (x direction) of the rear edge strip 110. Each reinforcing rib 116 is connected between the first flange 111 and the lower surface of the rear edge strip 110 so that a stable structure is formed therebetween. Of course, for the embodiment in which the second flange 112 is provided, each reinforcing rib 116 is connected between the first flange 111, the second flange 112, and the lower surface of the rear edge strip 110.

In some embodiments, referring to fig. 6 and 8, the upper surface of the rear edge strip 110 may include a concave curved surface 1102 with a central portion recessed downwardly from the front and rear edges. For example, the concave curved surface 1102 is a curved surface whose axis is parallel to the length direction (x direction) of the rear edge strip 110. This structural design further enhances the strength of the rear edge strip 110 so that it does not crack.

In some embodiments, the wall-mounted air conditioning indoor unit utilizes a vapor compression refrigeration cycle system for cooling/heating. An indoor heat exchanger and a fan (not shown) are provided in the casing 10. The indoor side heat exchanger and the throttling device are connected with a compressor, an outdoor side heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the interior of the machine shell 10 through an air inlet 11 at the top of the machine shell 10, and after forced convection heat exchange with an indoor side heat exchanger is completed, heat exchange air is formed and enters an air duct, and then the air is blown to the indoor environment through an air outlet 12 so as to regulate the indoor environment air.
