Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cleaning liquid for a vehicle evaporator using carbon powder and a cleaning device for a vaporizer using the same.

The present invention relates to a cleaning liquid for a vehicle evaporator using carbon powder and a cleaning apparatus for a vehicle evaporator using the same.

BACKGROUND ART [0002] Generally, an air conditioning system (HVAC) of a vehicle is a system in which air in a room is ventilated with fresh air from outside or air is circulated in the room to remove pollutants using a filter, It is a system that controls the heating, ventilation and supply control of the indoor air as a result by operating the indoor circulation mode of the air and the outdoor air introduction mode in accordance with the mode set by the user.

An evaporator is provided in the air conditioner of the vehicle to cool the temperature of the outside air by depriving the heat of the outside air by evaporating the refrigerant, and blowing the cooled air into the room using a blower to cool the room .

As the driving of the vehicle continues, various dusts and contaminants accumulate on the outer side of the evaporator. As a result, various bacteria and fungi are propagated due to such contaminants, so that the air discharged into the room contains bacteria. And the unpleasant smell of the passengers makes them feel a strong dislike.

Therefore, in recent years, a cleaning liquid or the like sold in the form of a spray is used to clean the discharge port of the room or install a fragrance to the discharge port, but the cause of the odor is not fundamentally solved.

In order to solve such a problem, a technique of cleaning an evaporator of a vehicle using a separate cleaning device has been developed. As an example of such prior art, there is disclosed a cleaning and sterilizing device for a multipurpose automotive air conditioner evaporator of Patent Publication No. 2008-0089922 .

The cleaning and sterilizing apparatus disclosed in the patent document is configured to clean and sterilize the surface of the evaporator by high-pressure spraying of the cleaning liquid or the sterilizing agent using a high-pressure pump.

However, contaminants adhered to the surface of the evaporator for a long period of time are not easily removed even when water is sprayed at a high pressure. Even if sterilized by a sterilizing agent or the like, contaminants such as fungi or bacteria easily reproduce again.

Therefore, it is required to develop a cleaning liquid and a cleaning device capable of easily removing pollutants fixed on the surface of the evaporator and suppressing the propagation of bacteria such as fungi.

Hereinafter, the cleaning liquid and water used in the above-described cleaning apparatus will be described.

The washing liquid is a mixed liquid containing wood vinegar, water, carbon powder and additives.

Wood vinegar refers to a liquid substance that is obtained by liquefying the smoke generated during the charring process of trees and then removing toxic and harmful substances by aging the smoke. Such wood vinegar has a pale red color and a strong smell. It has acidity around pH 3, and the main component contains 80 to 90% of water, 3% of acetic acid, and a small amount of organic matter of 200 kinds such as formic acid, fatty acid and methanol.

These vinegar solutions are widely used as deodorants, raw materials for pesticides, additives for livestock feed, raw materials for medicines such as prescription drugs and orthopedic drugs, and additives for treating athlete's foot and atopic dermatitis.

When carbon char is carbonized at a high temperature, the impurities present in the raw material are carbonized and removed to obtain a carbonized material of 90% or more. The carbon powder is produced by pulverizing the carbonized material to a powder having a predetermined diameter (nm unit) .

In the present invention, the carbon powder is produced by carbonizing char, at a temperature in the range of 2,000 to 2,500 DEG C, and then cooling and pulverizing the powder into a fine powder. By this process, the impurities present in the raw materials such as charcoal are carbonized and removed, whereby the raw material becomes a carbon material having a carbon content of 95% or more. These carbons have numerous pores consisting of macroporous particles of 50 nm or more in diameter, mesoporous particles of 2 to 50 nm in size, and microporous particles of 0.8 to 2 nm in size inside the cell walls do. Due to the existence of these pores, the carbides have a very large surface area ranging from 660 to 1,320 m 2 per 1 g. Particularly, micropores are formed when hydrogen, carbon, or molecules are volatilized during carbonization, and are suitable for microorganisms such as bacteria and radionuclides to be inhabited. In addition, they have excellent adsorption ability due to large surface area, And the ability to adsorb or remove odors.

Such carbon powder adsorbs and removes pollutants adhered to (or adhered to) the surface of an evaporator and various bacteria, and suppresses the propagation of various bacteria such as fungi. The carbon powder also prevents oxidation of the structure or device and prevents aging of the structure or device.

The additive includes a surfactant. The surfactant is also referred to as a surface active agent and is widely used as an additive for various detergents, soaps, shampoos and cosmetics to separate and clean the surface oil.

The washing solution is prepared by mixing 70 to 80 parts by weight of wood vinegar, 10 to 15 parts by weight of water, 3 to 7 parts by weight of carbon powder and 3 to 10 parts by weight of additives, based on 100 parts by weight of a mixed solution containing wood vinegar, water, carbon powder and additives. Mixed.

Since the wood vinegar is a liquid having a viscosity higher than that of water, if it is mixed in excess of 80, liquidity is inhibited and mixing is not easy. Also, when mixed with water to the surface of the evaporator, the function of adsorbing to the surface of the evaporator is lowered and the removal performance of the contaminants is lowered.

In addition, when the carbon powder is mixed more than 7, there is a disadvantage that the carbon powder is easily aggregated in the washing liquid. On the other hand, mixing less than 3 deteriorates the ability to suppress the adsorption of fungi and various bacteria, and to suppress the growth of bacteria such as fungi.

Also, the oil separation performance of the additives varies depending on the amount of the surfactant mixed.

The water is mixed with the washing water at a certain ratio and injected to ensure proper fluidity, and at the time of the second washing, the washing liquid adhered to the surface of the evaporator is removed.

It is more preferable that such water is used for mineral water. Mineral water has a range of 4.2 ~ 5.2 pH and it contains Ca, Si, Mg, K, and Na. It has a high content of manganese (Mg) instead of iron (Fe)

In addition, the carbonic acid (CO ₂ ) contained in the mineral water has an effect of self-sterilizing and sterilizing the object to be cleaned. When the mineral water (water) is mixed with the washing water, the contaminants adhered to the carbonic acid in the mineral water are peeled off, so that the adsorption performance by the carbon powder is further enhanced and the sterilizing action by the carbonic acid can be expected.

INDUSTRIAL APPLICABILITY As described above, the present invention effectively adsorbs and sterilizes contaminated pollutants and various bacteria using carbon of wood vinegar, carbon powder and mineral water. In addition, a small amount of carbon powder sprayed on the surface of the evaporator prevents the growth of bacteria such as molds continuously, and also prevents the deterioration of the evaporator as an antioxidant.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
