The cleaning device of heat exchanger of air conditioner outdoor unit of the present invention stores spare water for cleaning by the way that the second water tank 2 is arranged, if
It sets reversing control valve 3 and switches the first water tank 1 or the output of the second water tank 2, recycle controller 5 according to refrigeration or heating condition, it is right
It controls reversing control valve 3 with answering, so that outdoor machine of air-conditioner heat exchanger is either in cooling condition or heating condition, can obtain
Effectively automatic cleaning, to correspondingly ensure that the efficiency of air conditioner.
Further, controller 5 includes the first wash phase when entering refrigeration cleaning model or heating cleaning model
And second wash phase, wherein
In the first wash phase, controller 5 is to control the compressor of air conditioner and the wind wheel of air-conditioner outdoor unit 100 with low
It is run in the revolving speed of nominal situation；
In the second wash phase, controller 5 restores to the wind wheel of the compressor and air-conditioner outdoor unit 100 that control air conditioner
Revolving speed to nominal situation is run.
In the present embodiment, the cleaning of the heat exchanger of air-conditioner outdoor unit 100 is at least divided into two stages: the first wash phase
And second wash phase, in the first wash phase, frequency-changeable compressor can reduce revolving speed, and invariable frequency compressor can stop transporting
Row.The wind wheel of air-conditioner outdoor unit 100 reduces revolving speed, so that the water of spray head (43a, 43b) sprinkling is able to front and washes away outside air conditioning chamber
Bulky grain dust on the outside of the heat exchanger of machine 100, meanwhile, the water of spray head (43a, 43b) sprinkling can be infiltrated to air-conditioner outdoor unit 100
Heat exchanger fin root.In the second wash phase, the heat exchanger of compressor and air-conditioner outdoor unit 100 restores to normal work
Condition, at this point, clearing up in combination with the wind-force of wind wheel smaller particle dust on the heat exchanger of air-conditioner outdoor unit 100.
It further, further include the first flow detection device 6 and second flow detection device being electrically connected with controller 5
7, wherein
Output of the first flow detection device 6 to detect the first water tank 1 when entering and freezing cleaning model in controller 5
Flow V1；
