AIR-CLEANING DEVICE FOR EVAPORATOR OF VEHICLE AND AIR-CLEANING DEVICE CONTROL METHOD FOR EVAPORATOR OF VEHICLE

摘要

The present invention relates to a sterilization apparatus for an evaporator of a vehicle air conditioning system and a control method thereof; The purpose is to intermittently sterilize the evaporator of the vehicle air conditioning system where mold and bacteria can inhabit through the sterilization lamp even when the vehicle is turned off, and at the same time, by intermittently forcibly circulating the vehicle indoor air, the purified air is always purified. It is to be able to supply it to the interior of the vehicle. To this end, according to the evaporator sterilization device 100 of the vehicle air conditioning system according to the present invention; A sterilization lamp 130 disposed around the evaporator 50 of the vehicle air conditioning system for circulating the vehicle indoor air by driving the blower unit 20 through the evaporator 50; A start detection unit 160 configured to detect vehicle start on/off by sensing vehicle power provided from the vehicle battery 80; A charging battery 300 capable of providing auxiliary power by charging vehicle power provided from the vehicle battery 80; A power supply unit 200 for supplying auxiliary power of the rechargeable battery 300 as operation power when the vehicle is turned off according to a detection result of the start detection unit 160; A relay 190 for intermittently supplying and controlling auxiliary power of the rechargeable battery 300 to the blower unit 20 when the vehicle is turned off; When the vehicle is turned off, auxiliary power is provided to the rechargeable battery 300 through the power supply unit 200 to continuously drive the sterilization lamp 130 for a predetermined time and then turn it off. A control unit 110 that drives the sterilization lamp 130 at a period of time and controls the drive of the blower unit 20 through the relay 190 to circulate the indoor air of the vehicle; It characterized in that it is provided.
