Description

Air purifier for vehicle air conditioner

The present invention relates to an air purifier for a vehicle air conditioner, and to an air purifier for a vehicle air conditioner capable of sterilizing by irradiating ultraviolet rays to an evaporator of the vehicle air conditioner.

In general, an air conditioner for a vehicle compresses a refrigerant by a compressor driven by receiving power from an engine, sends it to a condenser, condenses the refrigerant by forced blowing of a cooling fan in the condenser, and then converts the refrigerant to a receiver dryer, In the process of returning to the compressor by passing through the expansion valve and the evaporator in turn, the air blown by the blower unit installed at the inlet end of the air conditioning case exchanges heat with the refrigerant passing through the evaporator, and blows into a cold state a cooling device for cooling the interior of the vehicle by discharging air into the interior of the vehicle; In the process of returning the engine coolant to the engine through the heater core, the air blown by the blower fan of the blower unit exchanges heat with the coolant passing through the heater core, and the blown air that has become warm is discharged into the interior of the vehicle. By doing so, it includes a heating device for heating the interior of the vehicle.

At this time, if the vehicle air conditioner is continuously operated, when the blowing air flowing in from the outside of the vehicle passes through the evaporator, the odor or bacteria generated from the evaporator flows into the interior of the vehicle as it is, and when the air conditioner is stopped after operating , since the temperature of the surface of the evaporator rises sharply, bacteria and mold are relatively very active and multiply due to the condensate remaining in the evaporator, which leads to a problem in that the air quality inside the vehicle deteriorates.
