[0021] Specifically, in the splicing and combination water receiving tray structure described in this embodiment, before installing the water tank 2 and the tray, the length of the heat exchanger is first used to determine whether to connect the fixed tray 1 and the extension tray, so that the length of the overall tray can match the length of the heat exchanger. Then, when installing the overall tray and the water tank 2, the fixing block 12 and the fixing groove 32 are first misaligned in the length direction.

In addition, the rotary cover 42 can protect the water immersion switch 41 from water in the fixed tray 1 and can also repair the switch without disassembling the fixed tray 1, thereby reducing the maintenance cost.

[0030] Specifically, when the heat exchanger with a shorter length is matched, the first extension tray 91 and the fixed tray 1 are separated at the cutting line 93, and then the fixed tray 1 is installed on the water tank 2, so that the length space occupation of the whole can be reduced.

[0034] The water level switch 54 is provided on the top of the water inlet groove 22.

[0035] Specifically, since the water level switch 54 needs to be placed on the top of the water inlet groove 22 to accurately measure the water level of the water tank 2, the installation and fixing position of the water level switch 54 needs to be adaptively changed.

[0036] When matching a heat exchanger with a shorter length, the first extension tray 91 and the fixed tray 1 are separated at the cutting line 93, and then the fixed tray 1 and the water tank 2 are installed, at this time the water level switch 54 is placed in the first placing groove 51, and the water level switch 54 is arranged on the top of the water inlet groove 22.
