The present invention relates to a vehicle air conditioning system plasma cleaning device, and more specifically, to a vehicle air conditioning system plasma cleaning device that prevents contamination of the evaporator of a vehicle air conditioner with plasma.

In general, a vehicle's air conditioning system adjusts the vehicle's interior environment to a comfortable environment for the driver and passengers, such as cooling or heating the vehicle interior or removing frost from the windshield.

This air conditioning system is equipped with both a cooling unit and a heating unit, and after selectively introducing outside or inside air, the air is cooled or heated and blown into the vehicle interior.

Here, the cooling unit of the vehicle air conditioning system is equipped with an evaporator to generate cold air, and when the air conditioning system operates, water droplets are generated in the evaporator due to the temperature difference with the air being heat exchanged, causing water droplets to form on the surface of the evaporator. is absorbed.

Therefore, when the vehicle's cooling unit is running, foreign substances in the air coming in from the outside may attach to water droplets, causing mold and bacteria to grow in the evaporator.

Accordingly, various devices are being developed to prevent the occurrence of mold and bacteria in evaporators.

For example, there was a vehicle air conditioning device equipped with a plasma reactor as disclosed in Korean Patent Publication No. 10-0534804.

However, vehicle air conditioning systems equipped with plasma reactors operate regardless of whether the vehicle is running, so if the ozone catalyst is not managed, there is a disadvantage in being exposed to ozone generated during operation of the plasma reactor.

For the above reasons, attempts are being made in the field to develop various devices to prevent the occurrence of mold and bacteria in evaporators, but satisfactory results have not been obtained to date.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in Figure 1, the vehicle air conditioning system plasma cleaning device 1 according to the present invention includes an air conditioning system 100; Plasma module 200; Controller 300; Includes.

The air conditioning system 100 of the present invention can blow air received from the interior/exterior air flap 110, which can introduce outside air or indoor air, into the interior of the vehicle 10 using a blower fan 120.

At this time, the outside air may be introduced into the vehicle 10.

Here, the bet may introduce indoor air of the vehicle 10.

At this time, an evaporator 130 that can cool the air delivered from the blower fan 120 may be provided.

Here, the front end of the evaporator 130 may be provided with a heater core 140 capable of heating the air delivered from the blower fan 120.

At this time, a plurality of air conditioning flaps 150 that can introduce or block cooled or heated air into the interior are provided to control the interior temperature of the vehicle 10.

The plasma module 200 of the present invention may be provided in the evaporator 130.

At this time, the plasma module 200 can sterilize the evaporator 130 by generating plasma.

Here, the plasma module 200 may have any conventional structure and method as long as it can be sterilized by plasma, and detailed description of the plasma module 200 will be omitted.

At this time, when the evaporator 130 is sterilized using the plasma module 200, oxygen in the air reacts with the plasma to generate a small amount of ozone, which may be harmful to the human body.

Thus, a controller 300 that controls the plasma module 200 may be provided.

At this time, the controller 300 includes a driving detection means 310, and the plasma module 200 can be operated when the vehicle is stopped according to the detection result of the driving sensing means 310.

Here, the driving detection means 310 can generally know whether the vehicle 10 is started through an ECU (Electronic Control Unit) provided to control the vehicle 10.

At this time, by detecting the driver or passenger through the passenger detection sensor 410, the device can be prevented from operating when the driver or passenger is inside the vehicle 10 with the engine turned off.

Here, as an example, when the plasma module 200 is operated, as shown in Figure 2, outside air is introduced, the blower fan 120 rotates at maximum speed, and the air conditioning flap 150 is opened to allow the vehicle ( 10) It can be blown indoors.

At this time, the controller 300 may partially open the window 500 of the vehicle 10 to discharge ozone or harmful air that may be generated when sterilizing the evaporator 130 to the outside.

Here, when the controller 300 completes sterilization of the evaporator 130 and stops the operation of the plasma module 200, the blower fan 120 operates for a certain period of time and the window 500 is partially opened. By maintaining and ventilating, it is possible to prevent ozone remaining indoors in the vehicle 10, which is harmful to the human body.

The vehicle air conditioning system plasma cleaning device (1) according to the present invention will be described in detail as follows.

In the present invention, the air conditioning system 100 is provided in the vehicle 10 and blows air received from the interior and exterior air flap 110, which can introduce outside air or inside air, into the interior of the vehicle 10 with a blower fan 120, An evaporator 130 capable of cooling the air delivered from the blower fan 120 may be provided.

Here, the front end of the evaporator 130 may be provided with a heater core 140 capable of heating the air delivered from the blower fan 120.

At this time, a plurality of air conditioning flaps 150 that can introduce or block cooled or heated air into the interior are provided to control the interior temperature of the vehicle 10.

Here, the plasma module 200 may be provided in the evaporator 130.

At this time, when the evaporator 130 is sterilized using the plasma module 200, oxygen in the air reacts with the plasma to generate a small amount of ozone, which may be harmful to passengers.

Here, a controller 200 is provided to control the plasma module 200 as shown in FIG. 3.

At this time, the controller 200 includes the operation detection means 310, so that the plasma module 200 can be operated when the vehicle is stopped according to the detection result of the operation detection means 310.

Here, the driving detection means 310 can generally know whether the vehicle 10 is started through an ECU (Electronic Control Unit) provided to control the vehicle 10.

In this case, if the plasma module 200 is operated solely on whether or not the vehicle 10 is started, the driver or passengers may be exposed to ozone when they are inside the vehicle 10 with the engine turned off.

Here, the passenger detection sensor 410 can prevent the device from operating when the driver or passenger is inside the vehicle 10 with the engine turned off.

At this time, when the vehicle 10 is stopped and there are no drivers or passengers, the controller 300 operates the plasma module 200, the internal and external air flaps 110 introduce external air, and the blower fan 120 operates at maximum speed. At the same time as it rotates, the air conditioning flap 150 is opened and air can be blown into the interior of the vehicle 10.

Additionally, in another embodiment, when the plasma module 200 is operated, the controller 300 operates the heater core 140 to further increase the sterilization effect.

Here, in addition to ozone generated by the operation of the plasma module 200 in the interior of the vehicle 10, harmful air may be generated when the evaporator 130 is sterilized and may be introduced into the interior of the vehicle 10.

At this time, the window 500 may be partially opened to discharge harmful air that may be generated when sterilizing the evaporator 130 to the outside.

Here, when the blower fan 120 is stopped immediately after sterilizing the evaporator 130 and the window 500 is immediately closed, harmful air may remain in the interior of the vehicle 10.

Therefore, when the operation of the plasma module 200 is stopped, the blower fan 120 is operated for a certain period of time and the window 500 is kept partially open for ventilation, thereby removing ozone or harmful air from the vehicle 10 that is harmful to the human body. It can be prevented from remaining in the interior of the vehicle 10.
