In an alternative embodiment, two assembly guides 23 are used, each having a guide land 231; in a manner that the guide table surfaces 231 are opposite, the two assembly guide structures 23 are respectively fixedly arranged on the inner side walls of the two ends of the housing 20 (specifically, on the inner side walls of the vertical two ends of the wall-mounted chassis 21); the guide lands 231 are engaged with the outwardly facing end surfaces of the fixing members at both longitudinal ends of the support member 11. Namely, the air duct assembly supporting structure 10 is inserted between the guiding table surfaces 231 of the two assembly guiding structures 23, and the assembly guiding structures 23 have the function of guiding installation and can also play a role of limiting support. Wherein the end surfaces of the fixing plates facing outward are defined opposite to the end surfaces of the connecting supports 11, and after the supporting structure 10 is vertically assembled into the housing 20, the two fixing plates are respectively located at both ends of the housing 20.

Specifically, as shown in fig. 5 to 7, the assembly guide structure 23 employs a guide bar with an "L" shaped cross section, one side of the L-shaped guide bar is fixed on the inner side wall of the housing along the shape, and the other side is used as a guide table 231. The fixing plates (the first fixing plate 12 and the second fixing plate 13) have an outer contour conforming to the shape of the inner side wall of the housing. One of the L-shaped guide bars (the lower guide bar 2301 and the upper guide bar 2302) is fixed to each of upper and lower ends of the housing 20, and edges of the outward facing end surfaces of the fixing plates (the first fixing plate 12 and the second fixing plate 13) are fitted into the housing 20 along the guide surfaces of the L-shaped guide bars (the lower guide bar 2301 and the upper guide bar 2302) in a guide manner. The L-shaped guide strip may be continuously fixed to the inner side wall of the housing, or may be fixed to the inner side wall of the housing in a segmented manner, as shown in fig. 6, and the L-shaped guide strip 23 (the lower guide strip 2301 and the upper guide strip 2302) is divided into two segments and is oppositely disposed on the inner side wall of one end of the housing.

In the vertical wall-mounted air conditioning indoor unit, the condensed water on the heat exchanger 31 will drop to the fixing plate (the first fixing plate 12 shown in fig. 2 and 3) at the lower end under the action of gravity, and the fixing plate is cooperatively arranged on the assembly guide structure 23 at the lower end, so in an alternative embodiment, the guide table 231 is provided with the water chute 232, and the outflow port of the water chute 232 is located above the water pan; the dropping condensed water is finally guided to the water receiving tray by the water guide groove 232. In particular, the length of the guide table 231 is generally greater than the length of the fixing plate in the corresponding direction for better guiding and supporting. Therefore, the water chute 232 is generally formed on the guide land 231 of the edge portion of the fixing plate.

In an alternative embodiment, water pan mounting positions are provided on the outer side surfaces of the fixing plates at both longitudinal ends of the support member 11, for mounting the water pan 40. The water pan installation positions are preset on the two fixing plates, so that when the vertical wall-mounted air conditioner indoor unit is assembled, the proper installation direction can be selected according to the actual installation environment, the limitation of the installation direction is avoided, and the adaptability of the vertical wall-mounted air conditioner indoor unit is improved. As shown in fig. 5, only the structure in which the drain pan 40 is attached to the lower end portion of the cylindrical casing 20 is shown, but the actual structure is not limited to this, and the drain pan 40 may be attached to the upper end portion of the cylindrical casing 20, so that the number of steps for attaching and detaching the drain pan when changing the attachment direction is reduced, and the attachment process is further simplified.

In an alternative embodiment, the display device (not shown) is capable of being switched between a first fixed position and a second fixed position; the first fixed position is switched to the second fixed position by rotating 180 °. The direction requirement of the display device is met when the vertical wall-mounted air conditioner indoor unit can be installed in a bidirectional selection mode according to the installation environment. Specifically, the display device is detachably mounted on the housing in the display direction in a conventional mounting manner (e.g., a mounting manner in which the electrical box is located at the lower end portion of the housing), and when the display device is actually mounted, the display device is detached and then assembled to the housing after being rotated by 180 ° if the conventional mounting manner needs to be changed. Or, the display device adopts a screen technology capable of automatically adjusting the display direction, and is similar to the automatic screen turning function of a mobile phone screen, so that the display device does not need to be disassembled and assembled.

In an alternative embodiment, one or more outlet ports 203 are formed on two ends and/or end caps of the cylindrical housing 20 to facilitate connection with external pipelines.

In an alternative embodiment, as shown in fig. 5, an electrical box 27 is further mounted at one end of the cylindrical housing 20. And the corresponding position of the cylindrical shell 20 for assembling the electrical box 27 is provided with an access window 271, which is convenient for the inspection of the electrical box. And a cover plate 272 is added on the access window 271 to protect the electrical box 27. Specifically, the opening position of the access window 271 may be opened according to the specific structure of the cylindrical housing 20. When the cylindrical casing 20 includes the support frame 26 as shown in fig. 5, the support frame 26 to which the end portion of the electrical equipment box 27 is attached may be provided with an access window 271. When the wall-mounted chassis 21 and the cylindrical case 20 of the support frame 26 are used as shown in fig. 8, the reinforcing plate 214 at the end of the wall-mounted chassis 21 to which the electrical box 27 is attached may be provided with an access window 271.
