Description

Automotive air filter {Automobile air filter}

The present invention relates to a filter frame and an air filter for a vehicle in which a filter filter paper made of a non-woven fabric is formed therein. More specifically, step by step of breeding and odor of foreign substances such as dust, dust, and mold or microorganisms introduced into the vehicle. A filter member using a photocatalyst and a circuit board and an electrode needle that generate negative ions by corona discharge due to a negative potential difference are sequentially provided in the filter frame so that the charcoal can be finally removed. The present invention relates to an air filter for a vehicle in which a filter member contained therein is used to purify the air flowing into a vehicle interior to create a comfortable indoor environment.

In general, the air in the air flowing into the car contains dust, pollen, dust, fine bacteria, and odors that cause allergies.In this way, the air flows into a closed vehicle without purifying the polluted air. If you do so, it can be unpleasant to the driver and passengers, and it can be fatal to your health such as shortness of breath. Therefore, dust, dust and bacterial harmful substances contained in the air outside the car should be removed from the inside of the car. It must be possible to flow in.

To this end, as shown in FIG. 12, an air filter 1 is installed and used in a vehicle air conditioner, and the air filter 1 used in this case repeats the filter filter paper 3 made of a nonwoven fabric with a triangular waveform many times. It is formed to be bent, and the filter filter paper (3) to form a filter frame (2) consisting of a rectangular box so as to be fixed therein and used to be mounted on the air inlet of the vehicle stably.

The filter filter paper 3 is a woven paper or non-woven fabric having a fine web, and serves to filter out dust or dust, and in particular, the filter filter paper 3 is a continuous triangle to increase the contact area with air per unit area. It has a shape bent into a waveform. In addition, the filter frame (2) is obtained by inserting the filter paper into the injection machine, spraying the PP resin or ABS resin raw material at a high pressure in the outer frame portion, and cooling, the filter paper (3) in the cooling process 2) Attached and fixed.

The fixed filter filter paper (3) has a simple structure that is fixed to the filter frame (2) in a state where the nonwoven fabric or the synthetic fiber is composed of one or two layers simply, so that the dust of relatively large particles may be filtered out. Fatal fine dust or dust had a problem that can not pass through as it is not filtered.

In addition, if the air filter is not frequently replaced, microorganisms such as mold or bacteria have been raised, which has been raised as a problem.

Recently, in order to secure such a problem, a technique of releasing anions and installing antibacterial and deodorizing charcoal at the air inlet has been introduced, but in this case, it is inconvenient to replace the installed charcoal because the coal is put into the air inlet as a lump. There was a point.

On the other hand, in order to secure the above problems, the technology used to fix the filter filter paper 3, which is used to apply activated carbon or charcoal to the non-woven fabric to the filter frame 2 has been applied for, the air filter 1 is activated carbon In the method of coating the charcoal, there is a problem that the air flow is not smooth because the web of the nonwoven fabric is blocked due to the minute difference between the content of the charcoal and the content ratio of the adhesive for attaching the charcoal to the nonwoven fabric.

In addition, the filter filter paper (3), which is simply coated with charcoal on a single nonwoven fabric, has a problem in that the antibacterial function due to the generation of negative ions is remarkably inferior in its working effect.

As described above, in order to maximize the function of the negative ions, air cleaners are widely used to purify the indoor air using an anion generator. However, when the air cleaner is installed and used in a car interior, foreign substances and molds directly introduced through the air conditioner and There was a problem that can not remove the microorganisms.

In the case of negative ions generated in air cleaners, the negative ions are generated by (-) and (+) currents, and ozone (O3) is generated as a by-product. It is pointed out that a very serious problem occurs when people who breathe indoors after prolonged exposure feel nauseous and even severe vomiting.

Especially for pregnant women, the elderly and children, it can be fatal to the health and cause headaches in the driver.

Recently, many air cleaners using photocatalysts have been developed, but are not directly applied to air filters.

Looking at the operation principle of the air cleaner using a photocatalyst, first, when the light energy emitted from the ultraviolet lamp is irradiated to the photocatalyst such as titanium oxide, electrons are transferred to the conduction band to generate electrons and holes, and the electrons and holes have strong oxidation and reducing power Since it reacts with water and oxygen in the air, it generates free radicals. In addition, the active oxygen has a strong binding force with other components, so as to destroy the binding of the odorous substance is not only deodorizing effect is made, but also OH radicals in the active oxygen has a strong oxidizing power to sterilize microorganisms, so that the active oxygen.

Accordingly, photocatalyst filters coated with titanium oxide are widely used in air cleaners, and the conventional photocatalyst filters are coated with titanium oxide on the surface of the filter, so that the titanium oxide film may be detached or the reflectance is degraded when used for a long time. .

In addition, the air cleaner as described above has a problem in that the structure is complicated and takes a lot of production cost and cannot be installed in a small volume such as a car air filter.

The present invention has been made in view of the above-mentioned conventional problems, and its object is to include a filtration member using a photocatalyst inside the filter frame, and a plurality of circuit boards and electrode needles that generate negative ions by corona discharge due to a negative potential difference.

It is to provide an air filter for a vehicle that can be formed.

Another object of the present invention is to impregnate the liquid titanium dioxide in the non-woven fabric, and the surface area of air contact is wide and the light of the ultraviolet lamp is irradiated to the filtering member as a whole, so that the photocatalyst is made smooth, so that the action of antibacterial, deodorization, antifouling, atmospheric purification, etc. To provide a car air filter that can maintain a comfortable indoor environment.

Another object of the present invention is to attach a plurality of pieces of titanium dioxide impregnated non-woven fabric at regular intervals on one side of the plate-shaped charcoal filter having a plurality of vents therein to reduce the thickness of the filtration member and at the same time improve productivity. It is to provide an air filter for automobiles.

Another object of the present invention is to generate a voltage difference of -10Kv on the first circuit board and -4Kv on the second circuit board to generate a potential difference by twice the voltage difference, and the ozone is generated when the discharge starts. The present invention provides an air filter for automobiles in which ozone is formed in a smaller amount than ozone generated when different polarities ((-) and (+)) are used, and a large amount of anions can be generated.

Another object of the present invention is to insert injection molding the filter member inside the filter frame, and to improve productivity by shortening the work process to easily combine the first and second circuit boards, the first and second electrode needles and the filtration member. Thus, to provide a car air filter that can be replaced to reduce the cost of the product.
