The mounting bracket 31 is able to be moved into or out of the inner cavity 113 through the opening of the inner cavity 113 along an up-down direction. Thus, the mounting bracket 31 may be pulled out from the opening of the inner cavity 113 when the air duct assembly 30 needs to be maintained, replaced, or cleaned, thereby providing convenience for maintenance, replacement, or cleaning of the air duct assembly 30 (including impeller, volute assembly 33, water receiving tray 35, etc.) and reducing after-sales maintenance costs. At the same time, the maintained, replaced, or cleaned air duct assembly 30 may be pushed upwards into the inner cavity 113 along the chassis 20 from the opening, and be connected with the face frame 11, thereby improving the installation stability of the air duct assembly 30. Therefore, the wall-mounted air conditioner indoor unit 100 of the present disclosure is easy to disassemble, assemble, and clean, and has high installation reliability, which greatly improves user experience comfort.

(28) Referring to FIGS. 6 to 12, in some embodiments, in order to facilitate the dismounting and mounting of the mounting bracket 31, the mounting bracket 31 includes an insertion member 311, the chassis 20 includes a sliding slot 221, and the insertion member 311 is movable in the sliding slot 221.

(29) Specifically, referring to FIGS. 11 and 12, the chassis 20 includes a base plate 21 and two side plates 22 extending forwards from two ends of the base plate 21, respectively, where the sliding slot 221 is one of two sliding slots 221, and each sliding slot 221 is formed at a corresponding side plate 22. The sliding slot 221 may be formed in various manners, for example, the sliding slot 221 may be depressed from the side plate 22; for another example, the one side plate 22 extends toward the other side plate 22 to form a limit portion, and the limit portion, the side plate 22, and the base plate 21 enclose to form the sliding slot 221. Each end of the mounting bracket 31 may be provided with an insertion member 311 corresponding to a sliding slot 221 (as shown in FIGS. 6 and 7). In this way, the insertion member 311 of the mounting bracket 31 may be slidably mounted in the sliding slot 221, so that on the one hand the dismounting and mounting of the mounting bracket 31 may be more convenient, and on the other hand it may be ensured that the mounting bracket 31 may move along the preset trajectory, which ensures that the mounting bracket 31 is mounted in position, thereby improving the installation reliability of the mounting bracket 31.

(30) In order to prevent the mounting bracket 31 from falling, the mounting bracket 31 may be locked and fixed with the chassis 20. For example, referring to FIGS. 9 to 12, each of the two ends of the base plate 21 includes a limit slot 223 adjacent to the corresponding sliding slot 221, and a locking latch 224 is disposed in each limit slot 223; the insertion member 311 includes a locking slot 312 corresponding to a locking latch 224 (as shown in FIG. 6). In this way, when the mounting bracket 31 is mounted, an upper end of each insertion member 311 is locked in a limit slot 223, and each locking latch 224 is locked in a locking slot 312 (as shown in the FIG. 10), so that the mounting bracket 31 may be locked and fixed with the chassis 20. When the mounting bracket 31 needs to be dismounted, the mounting bracket 31 may be detached from the chassis 20 by applying a downward pulling force to the mounting bracket 31.

(32) In some embodiments of the present disclosure, the sliding slot 221 defines a sliding trajectory of the insertion member 311, namely, defines a dismount trajectory of the mounting bracket 31. In order to avoid the occurrence of scratching of an input/output pipe assembly 51 of the heat exchanger 50 during the dismounting of the mounting bracket 31, the sliding trajectory may be inclined from a rear upper side toward a front lower side. Specifically, referring to FIG. 12, the sliding slot 221 includes a front slot wall 222 (namely the limit portion mentioned above) inclined forwards from top to bottom, and an angle α between the front slot wall 222 and a vertical direction (e.g., an extension direction of the sliding slot 221) is at least 0° and at most 89°.

(33) Referring to FIG. 9, the heat exchanger 50 includes the input/output pipe assembly 51 that includes a first pipe 52 and a second pipe 53. The first pipe 52 extends along a length direction of the heat exchanger 50 (left-right direction), and the second pipe 53 extends along an up-down direction. In order to avoid the occurrence of scratching of the input/output pipe assembly 51 during the dismounting and mounting of the air duct assembly 30, a limit plate 34 extending rearwards is disposed at a front end of the volute 331, and the limit plate 34 and an outer wall of the volute 331 enclose to form a first pipe slot 341 (as shown in FIG. 7), where the first pipe slot 341 is configured to accommodate the first pipe 52. In addition, the chassis 20 includes a second pipe slot 225 extending along an up-down direction (as shown in FIG. 11), and second pipe slot 225 is configured to accommodate the second pipe 53.

(34) Further, referring to FIG. 13, in some embodiment, the wall-mounted air conditioner indoor unit 100 further includes a wall-mount plate 40 disposed at the chassis 20 and detachably connected with the limit plate 34.

A plurality of the third screw holes 1111 may be provided, and spaced apart along a length direction of the face frame cross beam 111; a number of the fourth screw holes 314 corresponds to a number of the third screw holes 111. Here, the length direction of the face frame 11 can be a left-right direction shown in the figures.

(36) Referring to FIG. 14, on the basis of the above embodiments, the housing 10 includes an air outlet panel 12, and the air outlet panel 12 includes the air outlet. The air outlet panel 12 covers the opening, where the air outlet panel 12 is detachably connected with the mounting bracket 31, or the air outlet panel is detachably connected with the face frame 11, or the air outlet panel 12 is detachably connected with the mounting bracket 31 and the face frame 11.

(37) In some embodiments, the air outlet panel 12 may be detachably connected with the face frame 11. Thus, when the mounting bracket 31 needs to be dismounted, the air outlet panel 12 is first detached from the face frame 11, and then the mounting bracket 31 is pulled downwards from the opening.

(38) There are various ways of detachable connection between the air outlet panel 12 and the face frame 11, for example, the air outlet panel 12 may be snap-fitted with the face frame 11. Referring to FIG. 2 and FIG. 3, the face frame 11 includes two face frame side panels 112 disposed at two end of the chassis 20 along a length direction respectively, each face frame side panel 112 includes a flange 114 at a lower edge thereof and extending toward the other face frame side panel 112, and each end of the air outlet panel 12 is snap-fitted with a flange 114. Specifically, a first snapping buckle 121 is disposed at each end of the air outlet panel 12, each flange 114 includes a first snapping slot 115, and the first snapping buckle 121 is inserted in the corresponding first snapping slot 115. For another example, the air outlet panel 12 may be screwed with the face frame 11. Specifically, the air outlet panel 12 and the face frame 11 include corresponding holes, and the air outlet panel 12 and the face frame 11 are fixedly connected by screws inserted in the corresponding holes.

(39) In some embodiment, the air outlet panel 12 may be detachably connected with the mounting bracket 31. In this way, when the mounting bracket 31 needs to be dismounted, the air outlet panel 12 and the mounting bracket 31 may be first pulled out as a whole from the opening, and then the mounting bracket 31 may be further detached from the air outlet panel 12. Specifically, the air outlet panel 12 may be snap-fitted with the mounting bracket 31. Optionally, referring to FIG. 4, FIG. 5, and FIG. 14, a second snapping buckle 122 is disposed at the air outlet panel 12, the mounting bracket 31 includes a second snapping slot 315, and the second snapping buckle 122 is inserted in the second snapping slot 315. In order to increase the assembly reliability between the air outlet panel 12 and the mounting bracket 31, a plurality of the second snapping buckles 122 may be provided, and spaced apart along a length direction of the air outlet panel 12 (left-right direction).

(40) It should be understood that, in another embodiment, the air outlet panel 12 may be detachably connected with the mounting bracket 31, and the air outlet panel 12 may be detachably connected with the face frame 11. Thus, when the mounting bracket 31 needs to be dismounted, the air outlet panel 12 may be first detached from the face frame 11, and then the mounting bracket 31 may be pulled downwards from the opening. For brevity, the ways of detachable connection between the air outlet panel 12 and the mounting bracket 31, and the ways of detachable connection between the air outlet panel 12 and the face frame 11 are not repeated here.

(41) Further, referring to FIGS. 15 and 16, the wall-mounted air conditioner indoor unit 100 includes a front panel 60 movably connected with the face frame 11.
