Automobile air conditioner system peculiar smell removing device

Abstract

An ordor erasing device of an automobile air-condition system pertains to automobile electric system field, and comprises an evaporator, a heating device, an auto-control module, a fan, an air channel inlet, an air channel outlet, and an air channel; the heating device is arranged around the evaporator, the evaporator is arranged in the air channel. The auto-control module takes charge of receiving low-voltage input signal while the automobile air-condition stops operating, and an auto timer counts time, and the control signal is output to the heating device and the fan, and the input terminal of the auto-control module receives signal of the stopping operation of the air-condition. One output terminal of the auto-control module outputs an instruction to control the heating device, the other output terminal of the auto-control module outputs an instruction to control the fan. The fan is arranged between the air channel inlet in the air channel and the evaporator, and a terminal on the one side of the air channel that is arranged on the air channel is provided with the air channel outlet. The invention has the advantage of simple structure, reliable working, low cost, and can erase condensation water on the evaporator surface to prevent the breeding of bacteria, which can be used as standard equipment of the automobile.

Description

technical field [0001] The invention relates to a device in the field of automobile electrical systems, in particular to a deodorizing device for an automobile air-conditioning system. Background technique [0002] The air-conditioning system is the place where bacteria and mold accumulate in the car. The most important thing is that the mold will blow directly into the car with the air from the air conditioner to pollute the air in the car and produce peculiar smell, and at the same time pollute the human respiratory tract. The odor mainly comes from the evaporator of the air conditioning system. When the air conditioning system is in use, the water vapor in the air will condense into water droplets when passing through the fins of the evaporator; when the air conditioning system is turned off, the water droplets on the evaporator will not disappear immediately. , so as to form a humid, dark and closed environment conducive to the growth of bacteria and mold on the evaporat...

Problems solved by technology

At present, there are activated carbon air-conditioning filter products similar to the above-mentioned patents on the market. The price is about 200 yuan, and it needs to be replaced every six months, which is a relatively large expense for car owners.

Moreover, the above-mentioned patents all consider how to absorb or decompose the peculiar smell to achieve the purpose of removing the peculiar smell after the peculiar smell is generated, but they cannot fundamentally remove the peculiar smell. When the activated carbon fails, the peculiar smell will enter the car again.
