The first connecting pipe 24 communicates with the containing groove 221, and the condensate water formed by the air conditioning unit 11 is collected into the containing groove 221 through the first connecting pipe 24. It should be noted that the air conditioning unit 11 includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an indoor fan which are sequentially connected to form a refrigerant circuit. The indoor heat exchanger generates condensate water when in use. The condensate water is recycled into the water collecting barrel 22 through the first connecting pipe 24 to reduce the waste of water resources.

The pull rod 263 is reciprocally dragged along the vertical direction to drive the descaling ring 261 to move up and down, so that the brushes 264 on the outer peripheral wall of the descaling ring 261 repeatedly scratch the groove wall of the containing groove 221, thereby effectively cleaning the scale formed by the condensed water on the groove wall of the containing groove 221. The descaling assembly 26 has simple structure and is convenient to use. In addition, the filter 25 is arranged on the first connecting pipe 24, which can reduce impurities in the condensed water, thereby reducing the descaling frequency of the descaling assembly 26.

In the case that the pull rod 263 is provided with the handle 266, the diameter of the communication port can only allow the pull rod 263 to pass through, and the size of the handle 266 is larger than the diameter of the communication port and cannot pass through the communication port. Therefore, the detachable connection of the connecting rod 262 and the connecting portion 2621 facilitates the installation of the pull rod 263 and the descaling ring 261, and facilitates the disassembly of the pull rod 263 from the containing groove 221 and the separation of the pull rod 263 from the cover 23.

[0038] Further, the descaling assembly 26 further comprises a guide rod 265, the guide rod 265 is arranged on the groove bottom of the accommodating groove 221, and the length of the guide rod 265 extends in the vertical direction, a guide hole 2622 is arranged on the connecting rod 262 in the vertical direction, and the guide rod 265 is in sliding connection with the guide hole 2622.

[0040] Further, the collecting module 2 further comprises an overflow pipe 4, the overflow pipe 4 is connected to the outer peripheral wall of the water collecting barrel 22, and the overflow pipe 4 is adjacent to the slot of the accommodating groove 221.
