Description

Humidification air purifier {Wet type air purifier}

The present invention relates to a humidifying air purifier, and more specifically, a method for allowing pollutants to be adsorbed to the pleated filter by passing contaminated air through a pleated filter in the form of a fine net, and washing the adsorbed contaminants with water to purify the air. It is about humidifying air purifier.

In general, an air purifier for purifying air can be largely divided into a dry air purifier and a wet air purifier.

The dry air purifier includes a filtration filter type that filters through a HEPA filter and an activated carbon filter, an electrostatic precipitation type, a photocatalytic method using ultraviolet rays, a method using plasma, and the like.

Filtration The filter type has high filter replacement cost and limitations in removing ultrafine dust, the electrostatic precipitation type generates low dust collection efficiency and ozone, and the photocatalytic method using ultraviolet light and plasma method have potential harm to the human body. .

In particular, dry air purifiers are heated/dried and scatter to the upper part of the air purifier, so the window must be closed indoors and not suitable for outdoor use as it is weak against moisture.

In addition, the spring, which is mainly used for dry air purifiers, is dry, and the humidifier must be operated separately.

Wet air purifiers can be broadly divided into pleated filter type in which polluted air is brought into contact with the water film, and spray type, which is in contact with sprayed water droplets.

The wet filter type passes polluted air through the wet filter, so that pollutants are filtered and adsorbed/dissolved in the water film, so the purification efficiency is high. There is a disadvantage in that the wastewater that is being used has to be recovered and treated.

The spraying method has disadvantages such as high cost for spraying, low contact efficiency between spray droplets and polluted air, and difficulty in removing spray droplets, resulting in low equipment efficiency.

In particular, in the wet air purifier, the purified air is cooled by the evaporative cooling effect, becomes heavy and sinks to the ground, so that the economical efficiency of the purified air is higher than that of the dry air purifier.

Technology to solve these air purifier problems is being researched and developed.

As a related prior art, in Patent No. 10-1978028, "Water filter plasma air purifier", the plasma discharged polluted air is combined with the moisture of the water filter through contact with a water filter made of a hydrophilic fiber material attached to the wall. A technology that can remove fine dust and organic gas and sterilize various pathogens is being introduced.

As another prior art, in Patent No. 10-1931444 "Wet type air purifier", water particles injected into the air purifier collide with the introduced external air, and fine dust from the outside air is adsorbed to the water particles due to friction and friction. A technology to purify the air is being introduced.

And in Patent No. 10-1758984, "Air purifier with humidification control function", a technology that can purify air by primary filtering with a HEPA filter and secondary filtering by contact of water particles with a cyclone swirling flow has been introduced. .

However, in the prior art, the efficiency of removing harmful gas and fine dust may be low when the water filter attached to the wall and the polluted air come into contact, and the collision between the sprayed water particles and the air causes high noise, and a HEPA filter is used first. Filtering and contact between the cyclone swirling flow and water particles can increase the fine dust removal efficiency, but there are problems such as large and heavy equipment, and high noise problems.

In addition, the case 131 has a space inside the body and is formed with a predetermined length and width, and is provided with a plurality of connecting ribs 131a and 131b on the inside of the case 131, and the connecting ribs 131a and 131b. ) is a multi-layer structure facing up and down, and may be formed such that the upper/lower facing connecting spokes 131a and 131b are displaced from each other.

Here, the pleated filter 133 is installed in a repeating form in which the upper connecting flesh 131a of the case 131 is connected to the lower connecting flesh 131b, and the pleated filter is easily installed by the mutually misaligned structure. can do.

In addition, a filter fitting groove 131c formed in the form of an inner groove on the left and right sides of the case 131 to insert both ends of the pleated filter 133 to temporarily fix the filter fitting groove 131c may be further formed.

In addition, the case 131 is formed along the periphery of the edge where the connecting spokes 131a and 131b are formed, so that the presser 137 can be positioned in a stepped shape slightly lower than the height of the connecting piece. A large position groove 131d may be formed.

Here, the pleated filter 133 is repeatedly hung up and down by the connecting spokes 131a and 131b of the upper and lower multi-layered structure of the case 131 to be installed over mountains and valleys.

The pleated filter 133 is a fabric having a net structure in the form of a flat plate. The pleated filter has a shape of a long rectangle or a long ellipse in 2D, but has a relatively square or cylindrical shape in 3D when the pleated filter is manufactured.

The pleated filter 130 has a long rectangular or long oval shape, so that the filtration area is large and the filtration pressure loss can be reduced.

The edge of the pleated filter 133 is sewn after matching two or more layers of fabric or sewn thicker than the previously set thickness to form a water passage in some edge areas to delay the evaporation of water or the presser position groove (131d) allow it to settle on

When it is necessary to supply water to the middle portion of the pleated filter 133, sew two or more layers of fabric in the middle portion of the pleated filter or sew thicker than a previously set thickness to form a water passage.

It is preferable to move the water in the short axis direction because the moving distance is long to move the water in the long axis direction.

In addition, a wick filter 135 of a fabric may be connected to one end of the pleated filter 133 .

Preferably, the pleated filter 133 and the wick filter 135 are made of one of synthetic silk, acetate, cotton, hemp, polyester, nylon, PET, and polypropylene, and the pleated filter 200 has high moisture absorption. The material or shape is preferred.

Here, the pleated filter 133 is repeatedly hung up and down along the connecting spokes 131a and 131b of the upper and lower multi-layer structure of the case 131 to be installed in the form of mountains 133a and valleys 133b. However, in the shape of the peaks 133a and the valleys 133b of the pleated filter 133, the distance between the valleys and the peaks is preferably 5 mm or more.

In addition, the wick filter 135 connects the water supply tank 120 installed under the pleated filter 133 and the pleated filter 133 to supply water to the pleated filter by capillary action. In addition, although one wick filter is shown in one pleated filter, a plurality of wick filters may be further provided according to the area of the pleated filter.

Here, the supply of water from the water supply tank in which the wick filter is installed under the pleated filter prevents the formation of a water film in the pores of the pleated filter, and prevents oversupply and undersupply of water so that only the filter of the mesh can be coated with water. It can play an important role in preventing

In addition, the pollutants of the pleated filter can be sterilized by irradiation with ultraviolet or visible light, and dried to have an effect of intensively collecting pollutants and a sterilizing effect.

The presser 137 is closely attached along the edge of the pleated filter 133 that spans the connecting spokes 131a and 131b of the case 131 to fix the pleated filter 133 on the case 131 in close contact. can be formed so that

Here, the pressure bar 137 is preferably made of light and strong plastic capable of maintaining the shape of the pleated filter 133, but may be made of metal with good elasticity.

The blower 140 may be configured as a driving fan 142 driven by a motor inside the outer case 141 .

In addition, the blower may be an axial flow blower suitable for a product in which a humidification function is more important than an air cleaning function. In addition, the axial flow blower blows air in the axial direction, so the wind speed is fast, and the volume of the blower is small, so it is suitable for small products. On the other hand, in recent years, lightweight and small-sized, portable hand-held products are rapidly spreading. An axial flow blower would be suitable for such a handy type humidifying air purifier. In particular, the axial flow blower has a slow wind speed because the motor and the rotating shaft of the blower are located in the center of the shaft. If a cylindrical battery is placed in the center of this shaft, it will be possible to miniaturize it into a handy type without reducing the wind speed.

On the other hand, FIG. 6 is an exemplary view showing another embodiment of a filter case and a press bar according to the filter of the humidifying air purifier according to the present invention, wherein the press bar 137 is formed, but the wrinkle in contact with the case 130 While pressing the filter 133, it is brought into contact with the inner surface of the case 130, and the lower end of the presser 137 and the inner surface of the case 130 corresponding thereto are wedge-shaped V-shaped pressing protrusions ( 130a) and 137a may be respectively formed. At this time, the pleated filter can be more firmly positioned on the case by the V-shaped pressing protrusion.

On the other hand, FIG. 7 is an exemplary view showing a plan view and a side view of a case according to the filter of the humidifying air purifier according to the present invention as another exemplary embodiment.

A plurality of side holes 131e are provided on the side surface of the case 130, and further comprising a collection pad 150 inserted into the side holes 131e to contact the pleated filter 133 to collect contaminants. It can also be configured.

In addition, one side of the collecting pad 150 is formed in contact with the pleated filter 133 through the side hole 131e, and the other side is located on the side of the case 130 opposite to the pleated filter 133, and includes ultraviolet or visible light. It may be configured to receive light LED (not shown) irradiation.

In addition, the collection pad may be composed of a single material or a composite material among human silk, acetate, cotton, hemp, polyester, nylon, PET, and polypropylene.

In addition, since the size of the collection pad is located on the side of the case 130, it is very small compared to the pleated filter, and thus the concentration of the collected contaminants may be high. The collection pad with a high concentration of contaminants can be easily separated from the side hole 131e and disposed of.

In addition, since the collection pad is small in size, it is possible to maximize the effects of microbial sterilization, decomposition of pollutants and drying of the collection pad even if the output of the light source is low because the irradiation distance of ultraviolet or visible light is short.

253.7 nm irradiation is effective for sterilization of microorganisms, and there is an effect to prevent deterioration of the quality of purified air by microorganisms.

For the decomposition of the pollutants, irradiation at 250 to 450 nm is effective, and the decomposition of the pollutants has the effect of extending the period of use of the collection pad.

In the drying of the collection pad, the light source is the main cause, and the pleated filter becomes the driving force to move water to the collection pad, and contaminants contained in the water moving to the collection pad are collected by the collection pad.

In addition, drying of the collection pad is a phenomenon that occurs when the evaporation rate of water is greater than the supply rate of water even when the light source is not present. In the pleated filter, the higher the distance from the wick filter and the higher the position, the lower the water supply speed, so that the filter is dried first. Therefore, it will be effective to determine the location of the collection pad according to the position of the wick filter, the installation angle of the pleated filter, and the thickness of the pleated filter.

The selection of ultraviolet or visible light irradiating the collection pad may be selected depending on which effect is emphasized.

The selection of the LED and the lamp capable of irradiating the ultraviolet or visible light can be selected according to each feature, but the LED has advantages in volume, convenience, service life, power consumption, and the like.

On the other hand, FIG. 8 is another exemplary view of a case according to the pollution purification filter of the humidifying air purifier according to the present invention, wherein the case is provided with an inner case 130A and an outer case 130B that are vertically disassembled and assembled. , The inner case (130A) and the outer case (130B) have a space inside the body and are formed to have a predetermined length and width to have a plurality of connecting ribs (130A-1) and (130B-1) inside each, and the inside When the case 130A and the outer case 130B are coupled, the interconnecting ribs have a multi-layer structure facing up and down, and may be configured such that the connecting ribs facing up and down are displaced from each other.

The outer case 130B can be assembled to the inner case after the pleat filter is applied to the inner case connecting flesh 130A-1 to form troughs and mountains arbitrarily.

The inner case 130A and the outer case 130B improve the pleated filter, which is difficult to manufacture, into a structure that is easy to disassemble and assemble, so that the pleated filter can be easily manufactured and washed and reused.

Hereinafter, the operation and effect of the humidifying air purifier according to the present invention will be described. The following description is in accordance with the above structure description.

Briefly explain the purification process of polluted air using pleated filter. When the blower is operated and polluted air is introduced, the polluted air passes through the mesh of the pleated filter 133 wet with water, and the pollutants are adsorbed to the water of the mesh.

At this time, the important thing is that the finer the pores of the filter are, the better the filter's pores are to increase the removal efficiency of pollutants, but the air volume is sharply reduced.

In order to solve this problem, a pleated filter capable of increasing the filtration area was attempted.

In addition, it is important that water is coated only on the filter of the mesh while preventing the formation of a water film in the pores of the mesh. If water is supplied to the net in excess, the pores are clogged due to the formation of a water film on the pores.

That is, when a water film is formed in the pores, water droplets are scattered, the filtration efficiency is extremely reduced, and a high wind pressure/high noise blower is required. Therefore, in the present invention, it is focused on a technology that prevents the formation of a water film on the pores and allows water to be coated only on the filter of the mesh.

In addition, in the present invention, pollutants are collected from the pleated filter to keep the pleated filter as clean as possible, and the pleated filter can be easily replaced or washed before use.

The water movement path of the present invention has a definite difference compared to other inventions, and the flow of water will be briefly described. The water in the water supply tank moves to the pleated filter due to the capillary action of the wick filter, and after purifying the polluted air while moving from the pleated filter by capillary action or gravity, the water containing contaminants reaches the drying start point. Water containing contaminants that have reached the drying start point evaporates, and the pollutants that have been moved into the water remain at the drying start point and are fixed.

The drying start point is the point where the water supply rate and the water evaporation rate are the same, and it changes over time. As time passes and the water level in the water tank decreases, the drying start point moves toward the wick filter, and contaminants are concentrated to form a contaminant fixation zone.

What is unusual is that when the water in the water tank is replenished or the wind speed of the fan is lowered, the contaminant fixing zone moves to the opposite side of the wick filter.

That is, if the water level change in the water supply tank and the wind speed change of the fan continue, the contaminant fixing zone is continuously pushed up to the opposite side of the wick filter, so that the contaminant is continuously concentrated and fixed to the collection pad 150 .

Evaporation of water at the starting point of drying provides direct power to move pollutants from the pleated filter to the starting point of drying, and is an important factor affecting the service life and filtration quality of the pleated filter. In addition, since water evaporates at the starting point of drying, it is not necessary to provide a drainage tank, there is an advantage that water leakage does not occur, and there is an advantage that wastewater discharged outside the body does not occur.

As described above, the present invention does not discharge water to the outside of the main body, increases the efficiency of removing fine dust adsorbed on the pleated filter, minimizes water leakage when the device is overturned or portable, and places the water supply tank in the lower part to reduce the weight of the device. It is to provide a humidifying air purifier with a lower center of gravity, rapid removal of moisture and sterilization inside the device to suppress the growth of microorganisms, and portable and easy-to-large size.

Although the present invention has been illustrated and described with reference to preferred embodiments as described above, it is not limited to the above-described embodiments, and those of ordinary skill in the art to which the present invention pertains within the scope not departing from the spirit of the present invention Of course, various modifications and variations are possible within the technical spirit of the present invention and the equivalent scope of the claims to be described below.
