The present invention relates to a water filter air purifier, and more particularly, to form a "U" shape so as to fill the wash tube at the return point with the return point at the bottom of the open tube on both sides, and the axis of rotation vertically vertically to the left tube of the return point Install a blade for blowing air in order to suck contaminated air, a grinding blade for crushing washing water and contaminants, and a blade for cleaning contaminants with a whirlwind; The first air captures only contaminants by colliding the air and the sprayed water sprayed through the mist through the sprayed nozzles, and using the grinding blade, randomly grinds the contaminated air, and finely grinds it to provide centrifugal force. By forming a flow path between the side walls, the contaminants passing through the secondary The cleaning blades are used to swirl the contaminants through the wash water, and they are enclosed in bubbles and collected again by swirling the contaminants that are bypassed. The final contaminants are drained with the wash water, and the purified air It only relates to a water filter air purifier that discharges.

In general, an air purifier is a mechanism that discharges clean air after removing contaminants through a purification medium for air containing fine dust, various harmful gases, various germs, molds, viruses, and the like. The air purifier as described above is equipped with a variety of functions, such as air odor removal, removal of life odor, mites, pollen, small particles such as pet hair, disease caused by air infection.

The above air cleaner is divided into two types, dry and wet, and the dry is classified into two types: electrostatic precipitating and filter filtration.

The electrostatic precipitating has the advantage that there is no need to replace the filter because there is no filter, but when dust accumulates on the electrostatic precipitating plate, there is a disadvantage in that the purification ability is low and the ability to remove dust is weak.

In addition, the filter filtration type is excellent in purifying ability because it filters various particulates from the filter as air flows between the filters, but has a disadvantage in that a filter replacement cost for maintenance is required because the filter needs to be periodically replaced. In particular, particulate contaminants larger than the filter holes are effectively removed, but it is difficult to remove less fine dust and harmful gases, bacteria and molds than the filter holes, and the filter is often clogged and the filter has to be replaced frequently. There is a problem.

Compared to the dry type, the wet air cleaner does not need to replace the filter in such a manner that the suspended air is contacted with water to precipitate suspended substances in the water, and thus, it has the advantage of low noise and a humidifier function. In addition, the wet air purifier as described above is used to finely spray the water from the nozzle to collect bacteria, dust, etc. This is useful for filtering fine dust or removing microorganisms in the air compared to a dry air cleaner.

However, conventional wet air air cleaners usually have a limitation in that the device is complicated, large in size, and inefficient in terms of cost. Recently, a small wet air cleaner has been introduced, but there is still a problem in the removal of coarse dust or fine dust.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to use a wet air purifier, water filter air purifier easy to collect regardless of the size of the contaminated particles To provide.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of a water filter air cleaner according to the present invention having the configuration as described above will be described in detail.

As shown in FIG. 1, the water filter air cleaner 100 of the present invention is open to both sides, and contaminated air passes therethrough, and a lower portion of the tube 110 filled with washing water at a predetermined level. Spray 120 for spraying the washing water to the air, and the fan 130 to induce the flow of air, such as to suck the polluted air and discharge the purified air and the tube 110, the fan 130 therein And other air purifying facilities, including a case (not shown) that protects the facility from external impacts.

The tube 110, one side is provided with an inlet 112 through which contaminated air is introduced, and the other side is provided with an outlet 114 through which the purified air is discharged, so that the contaminated air can be purified while passing. It is formed as long as possible, and has a "U" shaped pipe shape with a return point at the bottom to fill the washing water that divides the air into contaminated and purified parts in the middle.

On the other hand, the lower portion of the tube 110, through which the purified air is discharged, is provided with a separate drainer 116 through which the washing water containing contaminants is discharged. The drainer 116 determines the level of the wash water, and is formed at a height such that the return point of the tube 110 can always be locked by the wash water. If the lower portion of the tube 110 is not locked because contaminants can be discharged to the drainer 116 without filtration. The drainer 116 may further include a drain pipe (not shown) for guiding the contaminated washing water to the outside of the case (not shown). As such, the reason why the water is always drained through the drainer 116 is that when the water stays for a long time without flowing the wash water, the original purifying process cannot be realized.

On the other hand, if contaminants accumulate repeatedly in flowing water, it is necessary to artificially remove the contaminants. In this embodiment, a stopper 119 is detachably attached to the lower part of the tube 110 to provide a regular tube ( The inner side of 110) should be cleaned. At this time, when the air purifier 100 is operated in a state in which the stopper 119 is removed, the remaining contaminants may be neatly removed and cleaned without a separate cleaning.

The spray 120 is connected to the wash water storage tank (not shown) through the pipe 122 or connected to a water source (not shown) can be directly supplied to the wash water from the water source, the washing water for treatment in addition to water You can add scents or mix medicines to prevent various diseases, or you can add scents to remove odors. The spray 120 is preferably installed at the side of the inlet 112 into which contaminated air is introduced, and a nozzle 124 for spraying the washing water is installed at the front side, and a separate agent for injecting the above-described medicine or perfume is provided. Input facilities may be further provided.

The washing water sprayed through the nozzle 124 of the spray 120 is filled in the lower portion of the tube 110 and flows with the flow of air and is discharged to the drainer 116. The spray 120 performs a function of collecting the pollutants primarily while the washing water is mixed with the contaminated air in the form of a water fog.

The fan 130 is installed on the rotary shaft 132 rotated by a motor (not shown), and the upper end of the rotary shaft 132, a plurality of blades are installed around the inside of the tube contaminated air Blowing blade 140 for guiding the flow to the rotary shaft, and installed in the middle of the rotating shaft 132, while hitting the contaminated air contaminates the contaminated air, finely ground, contact between the wash water and the contaminants A circulating blade 150 for collecting contaminants using centrifugal force and a lower surface of the rotary shaft 132 and rotating the washing water accumulated in the tube 110 by centrifugal force are expanded to generate a tornado. It consists of a blade for washing 160.

The blowing blade 140 sucks the contaminated air into the tube 110 and increases the pressure in the lower portion of the tube 110 so that the contaminated air can pass through the washing water filled in the lower portion by the pressure. Above all, the air flow must be strongly formed, and for this purpose, the blade is large so as to form airflow in the direction of the rotational axis like a conventional fan fan, and the blade itself is inclined to generate pressure in the forward direction. . Therefore, in the exemplary embodiment of the present invention, two blowing blades 140 are installed only at the upper end of the rotating shaft 132.

The grinding blade 150 is shaped like a fin, and unlike the blower blade 140, the blade itself does not need to be inclined, and the contaminated air and the washing water do not unilaterally escape but collide with each other. It is preferable that two or three are installed around the rotating shaft to descend, and the blades repeatedly installed above or below are alternately installed to have a zigzag shape when viewed from the side, and as shown in FIG. You can expect the effect of six blades installed.

The washing blade 160 is intended to remove contaminants from the air by providing a centrifugal force to the washing water to form a vortex so that the contaminated air and the washing water collide in earnest. Passing contaminated air leaving the wash water sufficiently dissolved in the wash water is most advantageous to remove the contaminants, but in some cases the contaminated air can be passed through as it is wrapped in a bubble without being purified. The bubble is broken to provide rotational force to the wash water to separate contaminants from the air.

The blade is not installed at a height corresponding to the surface of the washing water between the grinding blade 150 and the washing blade 160. The reason for forming the no blade zone on the rotating shaft in this way, the air flow descending by the blowing blade 140 at the top forms a mainstream, and under the water surface wash water by the washing blade 160 However, the pollutants are not sufficiently filtered by this method, and since the pollutants pass through the wash water, the pollutants are discharged to the outlet 114 as it is. By forming a temporarily rising air flow, the rising air and the falling air is collided with each other, and the concentrated air and washing water are concentrated in the collision area to remove contaminants and dilute the air by the increased pressure. Thirdly, pollutants are collected.

On the other hand, contaminated air does not pass through the inner wall of the tube 110 corresponding to the grinding blade 150 without being passed through as it is finely pulverized by the grinding blade 150, to secure a flow path of contaminants mixed with the washing water To form a plurality of concave-convex (118). Accordingly, the unevenness 118 is formed by the number corresponding to the number of the grinding blades 150, and the end of the grinding blade 150 extends to the extent that it does not collide with the side wall inside the unevenness 118, preferably Maintains a gap of between 1 mm and 2 mm and more specifically about 1.5 mm between the end of the blade 150 and the side wall. The contaminant proceeds downward while being pressurized to the inner wall of the tube 110 by the rotational force of the grinding blade 150, and the washing water particles and dust pressurized to the inner wall of the tube 110 are applied to the grinding blade 150. It is finely split by the secondary dust and is collected secondarily while only passing between the end of the blade and the side wall of the concave-convex 118 shape.

As shown in FIG. 6, the water filter air cleaner 200 according to another embodiment of the present invention includes a water collecting part 202 filled with washing water to a predetermined height, and an upper side of the water filter air cleaner 200, and contaminated air therein. The lower side is a tube 210 which is immersed in the washing water of the water collecting part 202 to a predetermined depth, a spray 220 for spraying the washing water to the contaminated air, and the inhaled air and discharged the purified air. As described above, the fan 230 which induces the flow of air or pulverizes the air and the washing water particles, and the collecting part 202, the tube 210, the fan 230, and other air purifying facilities are installed inside And a case 270 for protecting the facility.

The water collecting part 202 has a predetermined height to accommodate the washing water, and the upper part is open, and the washing water is always filled to a predetermined height, and the washing water is discharged while the washing water overflows. At this time, the upper part of the case 270 is formed with a discharge port 272 through which the purified air is discharged, and the lower part of the case 270 is discharged to discharge the contaminated washing water overflowed from the water collecting unit 202 to the outside (not shown). Not formed) is formed.

The tube 210 is sufficient to be formed vertically up and down only in the region where the fan 230 is installed, and the inlet 212 for introducing contaminated air from the outside may be formed on the side or the upper surface, but according to the present invention. In an embodiment, the tube 210 is shaped into a “T” shape, the left side is opened to form the inlet 212, and the right side is closed to install the spray 220.

The spray 120 is installed on the side of the inlet 212 through which the polluted air is introduced or on the opposite side thereof. The fan 230 is identical to the configuration and function of the fan 130 of the embodiment, the rotary shaft 232, and the blowing blades 240 to be installed at the top of the contaminated air sucked into the tube and , Installed in the middle of the rotating shaft 232 and colliding with the contaminated air to finely crush the contaminated air to enlarge the contact area between the washing water sprayed from the spray 220 and the contaminant, and using a centrifugal force It is composed of a crushing blade 250 for collecting dust and a washing blade 260 which is installed at the lower end of the rotary shaft 232, to rotate the washing water accumulated in the tube 210 by centrifugal force to generate a whirlwind. In addition, a plurality of irregularities 218 are formed inside the tube 210.

In particular, according to another embodiment of the present invention, the centrifugal force is formed in the lower portion of the tube by the washing blade 260 and form a vortex to remove contaminants from the air while the contaminated air and the washing water collide with each other. The contaminated air is very likely to leave the collecting part 202 as it is due to buoyancy beyond the lower end of the sieve tube 210 surrounded by bubbles, so that the air purification function is not sufficiently realized. Therefore, as shown in FIG. 7, the friction part 204 is further formed on the inner surface side of the water collecting part 202. The friction part 204 may be integrally formed on the inner surface side of the collecting part 202 or may be installed by separately processing the friction part 204, and the shape of the friction part 204 is not limited, but is only inside the collecting part. It is sufficient to increase the binding of contaminants and contaminants in contaminated air by destroying the bubbles surrounding the contaminated air by colliding with the swirling wash water by the rotational force.

Therefore, in another embodiment of the present invention, the contaminated air exiting the washing water is most advantageous to remove the contaminants passing through in a sufficiently dissolved state in the washing water, even if the uncontaminated sieve contaminated air is wrapped in a bubble In order to prevent the passage, the bubble is first broken by the cleaning blade 260 to separate contaminants from the air, and secondly, a friction part 204 is further formed on the inner surface side of the collecting part 202. As a result, the bubbles are completely crushed by friction, and are collected using the friction force.

Hereinafter, the operation of the air cleaner of the water filter according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

3 and 8, when power is applied to the motor, the rotating shafts 132 and 232 are driven, and the blowing blades 140 and 240 rotate so that the polluted air in the room is discharged to the inlets 112 and 212. Suction into the tube (110, 210) through. The washing water is supplied into the tubes 110 and 210 through the nozzles 124 and 224 of the spray 120 and 220 together with the operation of the rotary shafts 132 and 232, and the washing water is sprayed in the form of mist. At this time, the sprayed washing water and the contaminated air are coupled while colliding with each other, and contaminants in the air are first collected by the washing water.

As shown in FIGS. 4 and 9, the contaminated air passing through the tubes 110 and 210 is randomly crushed by the grinding blades 150 and 250 to be finely crushed, and the crushed contaminants and washing water are crushed. The particles are enlarged and the bonding area is more easily combined and collected again. Meanwhile, the inner walls of the tubes 110 and 210 corresponding to the grinding blades 150 and 250 are formed with a plurality of irregularities 118 and 218 extending outwardly, and the ends of the grinding blades 150 and 250 are irregular. (118, 218) Since it extends to maintain a gap of about 1.5mm with the inner wall, the contaminated air passing through the tubes (110, 210) while the flow path is formed by the gap is guided to the flow path, the blade 150, 250) It is more finely ground by the end, and secondary dust is collected on the side wall by centrifugal force.

As shown in FIGS. 5 and 10, the return point or the collecting part 202 of the tubes 110 and 210 is filled with the washing water, and the pressure is increased on the surface of the washing water by the blowing blades 140 and 240. Eventually, the air contaminated by the air pressure passes through the washing water, which is usually surrounded by bubbles and passes through the return point as it is, but whirlwinds are generated at the turning radius by the washing blades 160 and 260, and the rotating shafts 132 and 232 above the water surface. Since the blade is not provided at the blade), a vortex that locally swings up and down occurs, the bubbles are shattered, and the pollutants in the air are separated by the washing water and drained together with the washing water, thereby collecting the pollutants in the tertiary manner.

In this way, the polluted air is collected by using the washing water, and the purified air is discharged through the outlets 114 and 272, so that the polluted air introduced into the inlets 112 and 212 is purified by clean air and supplied to the room.

As described above, the present invention can be seen that the technical concept of the configuration of a wet air cleaner using a water filter. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.

As described above, according to the configuration of the present invention, the following effects can be expected.

First, the effect of first collecting only pollutants through the washing water sprayed in the form of mist from the spray nozzle using the blower blade is expected.

Second, using the grinding blade to randomly grind the contaminated air and water particles, and finely grind, and provide a centrifugal force to form a flow path between the blade and the side wall to secondary capture the contaminants passing through the side wall to the side wall The effect is expected.

Third, swirling the washing water through the pollutant using the blade for cleaning, crushing the pollutant bypassed by the whirlpool back to the whirlwind, draining the pollutant separated from the air into the wash water and purified air The effect of tertiary collection by discharge is expected.
