Self-cleaning device of automotive air-conditioning system and cleaning method thereof

Abstract

The invention provides a self-cleaning device of an automotive air-conditioning system and a cleaning method of the self-cleaning device and belongs to the technical field of automotive air conditioning. The self-cleaning device comprises an ultraviolet lamp, a cleanser spraying device, an ozone generator / negative ion generator, an air blower and a control module, wherein the ultraviolet lamp, the cleanser spraying device and the ozone generator / negative ion generator are fixed to an air conditioning cabinet assembly of the automotive air-conditioning system in an integrated mode, the air blower is arranged in the air conditioning cabinet assembly and is used for introducing airflow into the air conditioning cabinet assembly, and the control module is used for controlling the ultraviolet lamp, the cleanser spraying device and the ozone generator / negative ion generator. According to the automotive air-conditioning system integrated with the self-cleaning device, the self-cleaning function can be achieved conveniently and efficiently at low cost.

Description

technical field [0001] The invention belongs to the technical field of automobile air-conditioning, and relates to a self-cleaning device and a cleaning method of the automobile air-conditioning system. Background technique [0002] The automotive air-conditioning system is the main device for adjusting the environment in the driving compartment of the car. Its main function is to realize the preparation of cold air and hot air, and use different air outlet modes to realize blowing on the surface, blowing on the surface and feet, blowing on the feet, blowing on the feet to defrost, and defrosting. Cream and other functions. The air quality discharged by the automobile air-conditioning system directly affects the environment in the cockpit, and the cleanliness of the interior of the automobile air-conditioning system easily directly determines the air quality discharged by the automobile air-conditioning system. [0003] However, generally, the interior of the air-conditioni...

AI Technical Summary

Problems solved by technology

[0003] However, usually, the interior of the air-conditioning box of the automobile air-conditioning system is easily polluted by various factors, thus becoming a source of air pollution.

For example, when the air conditioning system is in the cooling mode, the air inside or outside the car passes through the blower of the air conditioning box, and the refrigerant flowing through the surface of the evaporator core and the refrigerant inside the evaporator absorbs heat and evaporates, while the air outside the evaporator is due to The heat absorbed by the refrigerant will be cooled, and when the surface temperature of the evaporator is lower than the air dew point temperature, the water vapor in the air will condense into water on the surface of the evaporator. Therefore, the inner surface of the air conditioning box and the surface of the evaporator , evaporator sealing sponge, etc. will be in a damp state, and when the air conditioner box is in this internal environment for a long time, it is easy to breed bacteria, mildew, odor, and breed mites. Various chemical substances that can cause odors brought into the air outside the car; such mildew and odors not only seriously reduce the comfort of the occupants in the car, but also easily cause dizziness, nausea, etc. after a long time, and even threaten the driving experience. Personnel are in good health, causing respiratory and other diseases

[0004] At present, the automotive air-conditioning systems that have been used have not been specially designed to solve the above problems. Therefore, after the after-sales problems such as peculiar smell have occurred, the smart car can be repaired or maintained to solve the problem, not only cannot completely solve the cleaning problem of the automotive air-conditioning system , and the cost is high, the implementation is very inconvenient, and the cleaning efficiency is low
