Method for controlling washing apparatus of air conditioner

Abstract

The invention relates to a control method for a washing apparatus of an air conditioner, which controls the flowing direction of the condensed water and determines the failure of the washing apparatus of the air conditioner according to the operation mode of the air conditioner. Therefore, the invention confirms the operation mode of the air conditioner; if the operation mode is a washing mode, then the condensed water generated by the air conditioner flows to the washing apparatus to generate the washing water and the generated washing water is transferred to the air conditioner again for washing a heat exchanger; if the operation mode is a normal mode, the condensed water generated by the air conditioner is exhausted to an external draining apparatus, thus changing the flowing direction of the condensed water according to the operation mode of the air conditioner so as to actively adjust the water supply for washing the air conditioner; furthermore, the invention measures the water level of water in a storage portion of the washing apparatus of the air conditioner or measures current flowing through a pump or the washing water generating portion of the washing apparatus of the air conditioner, thus determining whether correlated parts of the washing apparatus of the air conditioner are abnormal for answering the misoperation of the washing apparatus.

Description

technical field [0001] The invention relates to a control method of an external air conditioner cleaning device capable of sterilizing and cleaning an indoor heat exchanger. Background technique [0002] In general, an air conditioner is a device that cools, heats, or purifies sucked air and then discharges it by utilizing heat transfer generated during evaporation and condensation of a refrigerant to condition the air in a specific space. The air conditioner includes: a compressor that compresses the refrigerant as a working fluid to make the refrigerant into a high-temperature and high-pressure state; turns the high-temperature and high-pressure refrigerant compressed by the compressor into a liquid refrigerant and discharges internal latent heat to the outside a condenser; an expansion device that lowers the pressure by adjusting the flow rate of the refrigerant that becomes liquid in the condenser; an evaporator that absorbs external heat while evaporating the liquid ref...

AI Technical Summary

Problems solved by technology

When this air conditioner is not used for a long time, dust, bacteria, scale, etc. will be generated on the surface of the heat exchanger such as the condenser or evaporator. The efficiency of heat exchange decreases, and this dust, bacteria, scale can be the cause of an unpleasant smell when the heat exchanger is in operation

[0003] Therefore, it is necessary to carry out cleaning work to remove dust, bacteria, scale, etc. from the heat exchanger of the air conditioner. At this time, the user needs to disassemble and separate the heat exchanger and clean it all manually, or replace the heat exchanger itself. Incurring labor and exchange costs

Moreover, the heat exchanger of the air conditioner is limited by the installation place and installation method, so not only is it not easy to clean the heat exchanger by separating it, but it is also difficult to replace the heat exchanger in a limited space.
