Referring to FIG. 1 and FIG. 2, the rear case 100 includes a disk-shaped back frame 1 and a side plate 2 disposed at the edge of the back frame 1 in the embodiment. The side panel 2 is annularly disposed around the back frame 1, and the back frame 1 includes a boss 11 disposed at a middle portion, and two back plates 12 respectively connected to opposite sides of the boss 11;

The side plate 2 and the back plate 12 are disposed at an obtuse angle or a right angle, and the side plate 2 is located on a side of the back plate 12 facing away from the boss 11; the back plate 12 and the side plate 2 are respectively provided with an entrance grill 121.

In this embodiment, the boss 11 of the back frame 1 is mainly used for fixing with a support such as a wall, and the boss 11 may be disposed in a hollow or solid shape, but it is necessary to ensure a sufficient distance between the top back plates 12 thereof, thereby Wind in the environment can pass through the inlet grill 121 on the backing plate 12 along the air inlet passage between the backing plate 12 and the support.

It can be understood that since the outer frame 1 has a disk shape, the side of the back plate 12 away from the boss 11 is a convex arc edge. The side panels 2 are annularly disposed around the back frame 1, it being understood that the side panels 2 may be circular or polygonal. The side panel 2 may be enclosed with the back frame 1 to form an accommodation space of the rear case 100 or to be connected to the rear case 100 of the air conditioner indoor unit.

Specifically, the rear case 100 further includes an annular shroud 3 connected to the side of the side panel 2 facing away from the back panel 12, and the shroud 3 surrounds a space for accommodating the heat exchanger 200.

The air conditioner indoor unit rear case 100 of the present invention is provided with a boss 11 so that after the boss 11 and the wall and the like are fixed, an air inlet passage can be formed between the back plate 12 and the support, and at the same time on the back plate 12 and the side The inlet grill 121 is disposed on the panel 2, thereby expanding the air inlet area of the rear casing 100, and improving the air intake amount and heat exchange efficiency of the indoor unit.

Further, the boss 11 is hollow, including a wall panel 111 protruding from the back panel 12, and two inclined plates 112 respectively connected to opposite sides of the wall panel 111;

The wall panel 111 is provided with a wall-hanging hole, and the swash plate 112 is provided with an entrance grill 121, and the side of the swash plate 112 facing away from the wall panel 111 is connected to the back panel 12.

In the present embodiment, the boss 11 is hollow, which not only reduces the weight of the rear case 100, but also enlarges the heat exchange cavity in the rear case 100, thereby facilitating the opening of the style grid 121 on the swash plate 112. Thus, further The air inlet area of the rear case 100 is enlarged.

Further, the two back plates 12 are parallel to each other, and the wall plate 111 is parallel to the back plate 12, and as shown by d in FIG. 2, the vertical distance between the wall plate 111 and the back plate 12 is 10 to 100 mm. In this embodiment, the two back plates 12 may be located on the same plane or at a certain distance in the vertical direction, and the distance between the wall panel 111 and any of the backboards 12 is controlled within the above range, which may be better. Both the wind resistance and the outer dimensions of the rear case 100 in the front-rear direction are reduced, and the competitiveness of the air-conditioning indoor unit of the present embodiment is enhanced.

Further, the two back plates 12 are located on the same plane, so that the manufacturing cost of the rear case 100 can be reduced while ensuring a low level of wind resistance outside the back plate 12.

Further, the back plate 12 is perpendicular to the horizontal plane, and the air inlet of the inlet grill 121 on the backboard 12 is elongated, and the longitudinal direction of the air inlet extends along a first direction that is coplanar with the plane of the backboard 12 . In this way, the support strength of the backboard 12 is ensured, and the first direction is parallel to the plumb direction when installed.

Further, and as indicated by φ in FIG. 2, the angle between the swash plate 112 and the backing plate 12 ranges from 90 to 160 degrees. In this embodiment, it can be understood that, in the case where the distance between the back plate 12 and the wall panel 111 is determined, the larger the angle between the swash plate 112 and the back plate 12, the more the area of the back plate 12 is. Small, so that it will squeeze the area of the back panel 12 into the style grid 121; at the same time, the area of the swash plate 112 will increase accordingly. By setting the angle between the swash plate 112 and the back plate 12 to the above range, a large effective air intake area on the back frame 1 can be ensured.

Further, the opposite side edges of the wall panel 111 and the two slanting plates 112 are parallel to each other, so that the area of the wall panel 111 can be minimized, and the area of the swash plate 112 can be increased, so that the slanting plate 112 can be enlarged. The area of the area of the gate 121 also facilitates control of the corresponding dimensions of the swash plate 112.

Further, the opposite sides of the wall panel 111 connected to the two slanting plates 112 are perpendicular to the first direction, and the air inlet of the entrance grill 121 on the swash plate 112 extends along the oblique direction of the swash plate 112, similarly. Thus, the tensile strength of the rear case 100 at the portion of the swash plate 112 can be enhanced.

Further, the entrance grill 121 on the side panel 2 includes two first grid regions 21 in the vertical direction, and a second grid region 22 between the two first grid regions 21, the first grid The total flow area of the air inlet of the grid area 21 is greater than the total flow area of the air inlet of the second grid area 22, in other words, the effective air inlet area of all the air inlets in the first grid area 21 is larger than the second grid area 22 Effective air intake area for all air inlets.

In the present embodiment, the heat exchanger 200 is generally arranged in a block shape due to a general air-conditioning indoor unit, and is disposed at an angle with the back plate 12 or the slanting plate 112, and at the same time, enters the air from the inlet grill 121. The closer the angle between the direction and the heat exchanger 200 is to 90 degrees, the higher the heat exchange efficiency can be obtained. Therefore, the first grid area having a large total flow area is set in the first direction, that is, upper and lower. In the direction, it is advantageous to comprehensively improve the heat exchange efficiency of the wind entering from the side panel 2.

The present invention also provides a wall-mounted air conditioner indoor unit. Referring to FIG. 3 and FIG. 4, in an embodiment, the wall-mounted air conditioner indoor unit includes a heat exchanger 200 and an air conditioner indoor unit rear case 100, and the air conditioner indoor unit The specific structure of the rear case 100 is referred to the above embodiment. Since the wall-mounted air conditioner indoor unit adopts all the technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are no longer used. One by one.

The above description is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention, and the equivalent structural transformation made by the specification and the drawings of the present invention under the inventive concept of the present invention, or Direct/indirect use in other related technical fields is included in the scope of patent protection of the present invention.
