The first pipe section 205 corresponds to the first heat exchange section 101 , Is used to clean the first heat exchange section 101, and the second pipe section 206 corresponds to the second heat exchange section 102, and is used to clean the second heat exchange section 102. In other words, the shape of the outdoor heat exchanger 10 is adapted to the shape of the second sub-cleaning pipe 203, so that the second sub-cleaning pipe 203 can clean the outdoor heat exchanger 10 comprehensively.

Optionally, as shown in FIG. 3, the outdoor unit further includes a fan, the fan is arranged on one side of the outdoor heat exchanger 10, and the cleaning pipe 20 is arranged on the side of the outdoor heat exchanger 10 facing the fan.

Taking the outdoor heat exchanger 10 on the rear side of the outdoor unit and the fan on the front side of the outdoor heat exchanger 10 as an example, under the action of the fan, the wind passes through the outdoor heat exchanger 10 in a direction from back to front. Sundries such as dust, dust, etc. also pass through the outdoor heat exchanger 10 in a backward-to-front direction. The sundries are more likely to be blocked on the rear side of the outdoor heat exchanger 10. The cleaning pipe 20 is arranged on the fan side of the outdoor heat exchanger 10 Side, that is, the cleaning pipe 20 is arranged on the front side of the outdoor heat exchanger 10, so that the water sprayed from the water spray hole 201 of the cleaning pipe 20 flows through the gap between the radiating fins 106 in a front-to-back direction, which makes it easier to remove impurities Rinse away.
