In one embodiment, for the electrical control box 4, the mounting plate 42 is inserted downward to be clamped on the first jaw 140 of the supporting plate 14 for pre-positioning, and then the first extension plate 421 is fixed on the supporting plate 14 by screws.

In one embodiment, for the installation of other auxiliary devices, the installation space is mainly formed between the second mounting frame 133 and the side plate 12 on the adjacent side, and the sensor (such as a water level detector) and the drain pump 7 are installed in the installation space according to the requirement, and the water level detector and the drain pump are located in the installation space.

Specifically, in the assembly process, taking the sensor as a water level detector as an example, the water level detector may be inserted into the second mounting bracket 133 through the fixing bracket 61, and the fixing bracket 61 may be clamped at a lower position of the second mounting bracket 133 in a clamping manner.

And, for the drain pump, it is installed into the installation space through one of the installation openings 123 of the side plate 12. In order to conveniently and fixedly support the drain pump, the drain pump may be mounted on the corresponding baffle 124 through a pump mount.

In one embodiment, after the fan 3, the heat exchanger 2 and other related components are assembled, the water pan 5 is fastened to the heat exchanger 2, and finally, the bottom plate 13 is installed to complete the whole assembly operation.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
