Control method and control device for dust removal of condenser, storage medium and air conditioner
Technical Field
The invention relates to the technical field of air conditioners, in particular to a control method and a control device for dust removal of a condenser, a storage medium and an air conditioner.
Background
The outdoor unit in the air conditioner is in a severe working environment, wherein the back condenser is exposed in the air for a long time and is easy to accumulate dust and small impurities, and if the back condenser is not cleaned for a long time, the back condenser is easy to accumulate a lot of dust and small impurities, so that the condenser is blocked, the heat exchange of a refrigerant is influenced, and the refrigerating effect of the air conditioner is reduced.
In addition, when the outer fan works normally, the air flows from back to front, and the outer fan condenser is positioned on the back of the outer fan, so that dust carried in the air flow flows forwards through the condenser, and more dust is accumulated on the condenser.
In order to solve the above technical problems, those skilled in the art generally control the outer fan to reverse, but whether the rotation speed of the outer fan is controlled to be high speed wind or low speed wind, most of the outer fan has a constant speed, and some of the outer fan has a rotation speed which is gradually reduced. The condenser is cleaned by adopting the mode, and the cleaning effect is not ideal at present.
