A disinfectant composion for the airconditioner of vehicle

The present invention relates to a sedimentation sterilizing composition of an automobile air conditioner, and more particularly, to sterilize by spraying a sterilizing solution directly on an evaporator which easily forms mold and bacteria in the path of an automotive air conditioner and generates most of the air conditioner odor. It relates to a disinfectant composition for an air conditioner of a vehicle to remove the.

In general, automobiles are equipped with heating and cooling devices for comfortably creating indoor air. In particular, the air conditioner is a representative example of an air conditioner that controls the temperature, wind speed, humidity to create a comfortable interior of the vehicle.

The air conditioner is mainly composed of three types of units, respectively called a blower, an evaporator, or a heater unit.

First, the blower unit functions to blow indoor air or external air into the room by the power of a motor, and the speed is adjustable in three stages and four stages.

Secondly, the evaporator unit undergoes the process of compressing and expanding the refrigerant through the compressor by the force of the belt driven by the engine, circulating the cold refrigerant through the above process, and blowing the air by the blower force. It refers to a structure that blows air through an evaporator to blow the converted cold air into the room.

Third, the heater unit is connected with the coolant line of the engine so that when the engine is hot, the water temperature of the coolant is increased and the coolant is always circulated by the pump, so it is always warmed while the engine is running to warm according to the operation of the air flow path. Allow air to blow into the interior of the vehicle.

In the above-described conventional unit structure, an automobile having an air conditioner is operated when an air conditioner is operated, and inflow of odor is due to the structural characteristic of all air blown by the blower passing through the evaporator, and the evaporator is operated due to condensation water by cooling. Among the conditions that are always wet and provide a suitable place for the growth of mold and bacteria. In addition, when the air passing through the evaporator contaminated with mold and bacteria is blown into the car, respiratory disease or severe discomfort is caused to passengers in the car.

Conventionally, aerosol type disinfectant using compressed gas is used to solve this problem, but it must be injected through blower by injecting through the external inlet of the car, so it is not adsorbed to the blower and passage and reaches the evaporator, and the effect is not expected. It is true. In addition, masking by fragrance temporarily hides the odor, but does not fundamentally eliminate the cause of the odor, the effect does not last long. Generally, aerosol-type sterilizing deodorant is composed of ethyl alcohol, organic disinfectant, fragrance, and deodorant. It is used by filling compressed gas into pressure tube, and it is impossible to deeply penetrate the evaporator and to prevent dust. It is not easy to keep mold or bacteria inhabited.

In addition, as a prior art, the provisions of a device for forcibly evacuating air stagnant at the beginning of operation of an air conditioner, such as Patent 1998-0028343, and a method for preventing an initial odor from entering the interior of an automobile. Patents for exhausting air after spraying by installing a sterilizing liquid injector such as 0041157 and 1999-0041158 are applicable to new cars because they are a structural improvement of air conditioners. have. In particular, there is no mention of the sterilizing liquid and there is a problem that can not be a method of removing the odor of an effective air conditioner for a vehicle already sold and running.

In order to cope with this problem, some high-end vehicles recently marketed are equipped with an antibacterial deodorizing filter between the blower and the evaporator, so that replacement is possible. It is not a complete solution because there is a problem of getting into the radar and multiplying and causing odor.

The present invention is to solve the above-mentioned problems, to provide a bactericidal solution composition that prevents the generation of bad smell by removing the fungi and bacteria that inhabit by directly spraying the sterilizing solution to the evaporator of the car air conditioner Should be.

In order to achieve the above object, the present invention, the disinfectant composition of the present invention, the disinfectant composition directly injected into the evaporator polyhexamethyleneguanidine phosphate (PHMG) and alkyl dimethyl benzyl ammonium chloride (Alkyl dimethyl benzyl) ammonium chloride, or quaternary ammonium salt), characterized in that it contains at least one.

Hereinafter, the present invention will be described in detail.

Automotive air conditioners are divided into three main units: blowers, evaporators, and heaters. In addition, there are additional air flow dampers. The part which is easy to be contaminated by the dust and microorganism of the outside is a blower and an evaporator, and since the air filtered by the evaporator flows into the heater unit, the air condition is relatively good.

In particular, the evaporator is very advantageous in the growth of mold and bacteria by the condensed water by cooling when the air conditioner is operating. In fact, as a result of investigating the bacterial strain of the evaporator by prior investigation of the present invention, a large number of bacteria and fungi were found.

Among the representative strains that can cause diseases in the human body are bacteria (bacteria), the genus Staphylococcus, Pseudomonas, Corynebacterium (Corynebacterium), Flavobacterium (Flavobacterium) ), Bacillus genus, Micrococcus genus 6 species exist, and as a fungus (Fungi), Aspergillus genus, Cladosporum genus, Penicillium (Penicillium) genus three species were found to be present.

The above-listed strains are very important ones that can cause infections, respiratory diseases, allergies, etc., and these microorganisms cause malodor through metabolic processes. Therefore, the odor generated during the operation of the air conditioner can be easily removed by sterilizing the above-mentioned bacteria and fungi.

Sterilizing solution of the present invention can be easily processed by spraying in the following manner. The injection device is sprayed directly on the evaporator using a pressure of up to 6kgf / cm ² with a sterilizing solution in the spray gun for the compressor and the supplied medicine container which are owned by the general automobile maintenance shop.

Although there is a difference depending on the vehicle, in general, the blower is removed and sprayed using the space, and a vehicle with an antibacterial filter can secure a space by removing the filter.

Since the air conditioner of the vehicle varies in structure and the width of the passageway according to the type of vehicle, the spraying device of the spray gun can be easily bent in accordance with the bellows shape so that the angle can be easily adjusted.

The fungicide composition for removing the fungus and bacteria may be used by mixing at least one of polyhexamethyleneguanidine phosphate (hereinafter referred to as PHMG) and alkyl dimethyl benzyl ammonium chloride (hereinafter, quaternary ammonium spirit). .

The quaternary ammonium salt is C14, 50% of the composition by carbon number of the alkyl group; C12, 40%; C16, 10%, the average molecular weight is 342, 0.1-10% by weight of an aqueous solution having an effective concentration of 80% can be used.
