Automatic cleaning device for automobile air conditioner and corresponding vehicle

Abstract

The invention relates to an automatic cleaning device for an automobile air conditioner, which is set based on the HVAC assembly of the vehicle air conditioning system, and includes a hot gas reverse circulation channel, which connects the shell channel at the blower motor in the HVAC assembly and the heater The air outlet is located on the housing channel at the downwind direction of the evaporator when the air conditioner is clean; the switch mechanism for controlling the airflow path of the blower motor is located in the housing channel of the HVAC assembly ; The supply system used to provide cleaning agent, its outlet is set on the shell channel at the upwind direction of the evaporator when the air conditioner is cleaning; the control mechanism, its control signal output terminal is connected to the blower motor, the switch mechanism and the supply system. The invention has a simple structure, can automatically clean the evaporator when the vehicle air conditioner needs to be cleaned, prevents condensation water and dust from adhering to the evaporator, prevents bacteria from growing, and provides a good riding environment for people in the vehicle. The invention is applicable to air conditioning systems of various vehicles.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a vehicle air conditioner, in particular to an automatic cleaning device for an automobile air conditioner; the invention also relates to a vehicle with the above-mentioned automatic cleaning device for an air conditioner. Background technique [0002] With the continuous increase of vehicles, consumers have put forward higher requirements for the performance of vehicles. As an important part of the vehicle, the performance of the air conditioning system is getting more and more attention. Existing vehicle air-conditioning systems mainly include compressors, condensers, evaporators, and expansion valves or throttle tubes with switching functions. These four components are as follows: figure 1 As shown, metal or rubber refrigeration pipes are connected to form a closed space, and then the refrigerant can circulate in this closed space to cool or heat the environment in the ...
