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. It is equipped with a plurality of filter members and charcoal filtration member inside the filter frame to remove, purifying the air flowing into the car interior by filtration and sterilization action, antibacterial action and purification effect using anion and ozone (O3). It is to provide an air filter for automobiles to create an 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. 9, an air filter 1 is installed and used in an automobile air conditioner, and the air filter 1 used in this case repeats a 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.

Since the filter filter paper 3 is integrally fixed to the filter frame 2, when the filter filter paper 3 has reached the end of its life, only the filter filter paper 3 can be separated and replaced. There was a problem to use and exchange as a whole.

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.

In order to maximize the function of the negative ions as described above, air cleaners are widely used to purify the indoor air using an anion generator, but such air cleaners can be directly introduced through the air conditioner and the foreign substances and mold and There was a problem that can not remove the microorganisms.

In the case of negative ions generated in air cleaners, ozone (O3) is generated as a by-product when negative ions are generated. The higher the concentration of ozone is, the worse the health. A very serious problem that causes nausea and even severe vomiting has been pointed out.

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

The present invention has been made in view of the above-mentioned conventional problems, and its object is to provide a plurality of filter members, charge wires, and filtering members inside the filter frame, such as foreign substances, molds, microorganisms, such as dust, dust, and the like, which are introduced into a vehicle interior. Automotive air that filters and sterilizes breeding and odors step by step and generates a large amount of negative ions in a short time due to electrical contact between the charge wire and the filter member to create a pleasant interior environment by antibacterial and purifying action. In providing a filter.

Another object of the present invention is to provide a vehicle air filter that is easy to use and can be used by recycling only the filter member formed in the front and rear after a long time use.

Another object of the present invention is that when a negative current and a positive current are applied to the charge wire formed in the vertical direction, the current is amplified in the circumferential direction so as to make electrical contact with the filtration member formed of a charcoal rod to surround the outer edge of the charge wire. By generating more negative ions in the natural state at the same time to minimize the concentration of ozone (O3) by the antibacterial action of the filter member to eliminate the breeding and odor of mold and microorganisms by antibacterial and purifying action to maintain a pleasant indoor environment An automobile air filter is provided.

Another object of the present invention is to form a separate support frame to be easily combined and detached inside the filter frame to shorten the work process of the air filter and improve the productivity to reduce the cost of the product can be replaced car To provide an air filter for.

As shown in FIG. 1, the present invention enables easy coupling and separation of existing filter frames (2) and (10), while reducing the cost of the product, while excellent in filtration, sterilization, antibacterial, and purification functions. It is provided with an air filter (1) so that it can be maintained.

In the hollow part 11 formed at one side of the filter frame 10, fixing members 12 are formed at upper and lower portions, respectively, and the fixing member 12 has a semi-circular shape so that the filtration member 50 to be described later can be inserted and fixed. A receiving space portion 13 is formed, and insertion grooves 14 are formed on both front sides of the fixing member 12 so that one side of the first and second electrode plates 20 and 21 to be described later is inserted and fixed. To be able.

The fixing member 12 has a semicircular fixing member 12 formed around the center of the hollow part 11, and connection holes 15 are formed in upper and lower sides of the hollow part 11 to be described later. The first and second electrode plates 20 and 21 and the power supply device 80 may be electrically connected to each other.

The first and second electrode plates 20 and 21 are made of a plate body, one end of which is bent downward to have a bent surface 22, and is positioned horizontally above and below the hollow part 11 of the filter frame 10. As the side surface is inserted into the plurality of fixing members 12, the insertion groove 14 maintains the bent surface 23 in close contact with the front of the fixing member 12.

Meanwhile, one side of the first and second electrode plates 20 and 21 penetrates through the connection hole 15 of the filter frame 10 to protrude a predetermined length to the outside to be electrically connected to the power supply device 80 to be described later. Thus, (-) and (+) currents are supplied to the first and second electrode plates 20 and 21 so that (-) current and (+) current flow through the charge wire 30 to be described later.

The charge wire 30 is installed in the vertical direction to the first and second electrode plates 20 and 21, wherein the charge wire 30 is disposed in the receiving space portion 13 of the fixing member 12. One end is fixed to the second electrode plate 20 and 21 and the other end is not fixed, so that a negative current flows through the upper first electrode plate 20 so that the charge wire fixed to the first electrode plate 20 is fixed. The negative current flows in the zigzag direction so that negative current flows in the charge wire 30 in which negative current flows and is fixed to the second electrode plate 21 and the other end is not fixed. Let them intersect.
