Description

humidification air purifier

The present invention relates to a humidifying air purifier, and more particularly, to pass contaminated air through a fine net-shaped pleated filter so that contaminants are adsorbed to the pleated filter, and the adsorbed contaminants are washed with water to purify the air. It is about a humidifying air purifier.

In general, air purifiers for purifying air can be largely classified into dry type air purifiers and wet type air purifiers.

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

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

In particular, the dry air purifier is heated/dried and scatters the purified air upwards, so it must be used indoors with the windows closed, and is not suitable for outdoor use because it is weak against moisture.

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

Wet air purifiers can be roughly divided into a pleated filter type that contacts polluted air with a water film and a spray type that contacts sprayed water droplets.

The wet filter type passes contaminated air through the wet filter, and the contaminants are filtered and adsorbed/dissolved in the water film, so the purification efficiency is high, but a water film is formed in the pores of the wet filter, so a high wind pressure / high noise fan is required and contains pollutants There is a downside to collecting and disposing of wastewater.

The spray type has disadvantages such as high cost for spraying, low contact efficiency between spray droplets and contaminated air, and low equipment efficiency due to difficulty in removing spray droplets.

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

Research and development are being conducted on technologies to solve these air purifier problems.

As a related prior art, Patent No. 10-1978028 "Water filter plasma air purifier" combines plasma discharged polluted air with moisture in the water filter through contact with a water filter made of hydrophilic fibrous 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", the water particles injected into the air purifier and the inflowed external air collide and rub, causing the water particles to adsorb fine dust from the external air. A technology to purify the air has been introduced.

In addition, Patent No. 10-1758984 "Air purifier with a function of adjusting the amount of humidification" introduced a technology that can purify air by primary filtering with a HEPA filter and secondary filtering by contact between swirling cyclones and water particles. .

However, the prior art may have low efficiency in removing harmful gases and fine dust due to contact between the water filter attached to the wall and the contaminated air, and the collision between the sprayed water particles and the air causes high-pitched noise, and the HEPA filter first Filtering and contact of cyclone swirl flow and water particles can increase the efficiency of fine dust removal, but there are problems such as large and heavy equipment and high noise.

At this time, the filter connection hole 115 may serve as a water supply pipe serving as a passage for supplying water in the water supply tank 120 to the filter 130 on the upper side.

In addition, the main body 110 protrudes from the upper surface of the partition plate 111 and has a connector 116 having an elastic spring 116a embedded therein to elastically support the filter 130, and It is possible to form a plurality of filter holders 117 installed at the top to stably support the filter.

The water supply tank 120 has a structure with an open upper surface and is filled with water, and the partition plate 111 of the main body 110 can be configured to serve as a cover for the water supply tank 120. there is.

Preferably, the water supply tank 120 may seal the water supply tank by forming a female screw shape on an outer wall and forming a male screw on the inner wall of the main body to be fastened. In addition, a water supply pipe (not shown) capable of supplying water to the water supply tank may be inserted into the partition plate 111 as needed. In addition, the water supply tank may further include a transparent window (not shown) through which the amount of water supplied therein can be checked.

The filter 130 includes a case 131 formed in an open structure with a plurality of connecting teeth; a pleated filter 133 installed across the open front portion of the case 131 to absorb water and filter contaminants; a wick filter 135 connected to the pleated filter 133 and installed to transport water from the water supply tank 120; It is installed along the periphery of the pleat filter 133 and includes a presser 137 for pressing the pleat filter.

In addition, the case 131 has a space inside the body and is formed with a certain length and width, and is provided with a plurality of connecting

teeth

131a and 131b inside the case 131, but the connecting

teeth

131a and 131b ) is a multi-layer structure facing up and down, and the upper and lower

facing connection teeth

131a and 131b can be formed so that they are mutually offset.

Here, the pleat filter 133 is installed in a repetitive form that spans the upper connecting teeth 131a of the case 131 and connects to the lower connecting teeth 131b, and the pleat filter is easy to install due to the structure in which the connecting teeth are misaligned. can do.

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

In addition, the case 131 is formed along the circumference at the edges where the connecting

teeth

131a and 131b are formed, so that the pressing bar 137 is positioned in a stepped shape that is slightly lower than the height of the connecting teeth. A large location groove 131d may be formed.

Here, the pleat filter 133 is repeatedly hung up/down by the connecting

teeth

131a and 131b of the upper and lower multi-layer structure of the case 131, and is installed across the valleys.

The pleated filter 133 is a fabric having a net structure in the form of a flat plate. The wrinkle filter has a long rectangular or long elliptical shape in two dimensions, but forms a relatively square or cylindrical shape in three dimensions made of the pleat filter.

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 edges of the pleated filter 133 are sewn after matching two or more layers of fabric or sewn thicker than the previously set thickness to form a water movement passage in some edge areas to delay evaporation of water or press bar location groove 131d. allow it to settle into

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

Since it takes a long distance for water to move in the long axis direction, it is preferable to move the water in the short axis direction.

In addition, a wicking filter 135 of 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 artificial silk, acetate, cotton, hemp, polyester, nylon, PET, and polypropylene, and the pleated filter 200 has a high moisture absorption capacity. The material or shape is preferred.

Here, the pleated filter 133 is repeatedly hung up and down along the

connection teeth

131a and 131b of the upper and lower multi-layer structure of the case 131, which can be installed over the form of peaks 133a and valleys 133b. However, in the shape of the peaks 133a and valleys 133b of the pleated filter 133, it is preferable that the distance between the valleys and mountains is 5 mm or more.

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

Here, supplying water from the water supply tank in which the wick filter is installed below 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, contaminants of the pleat filter may be sterilized by irradiation with ultraviolet rays or visible rays and dried to have an effect of intensively collecting contaminants and a sterilization effect.

The presser 137 adheres closely along the edge of the pleat filter 133 spanning the

connection teeth

131a and 131b of the case 131 to tightly fix the pleat filter 133 on the case 131. can be formed so that

Here, the pressure bar 137 is preferably made of light and durable plastic capable of maintaining the shape of the pleated filter 133, but may also 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 humidifying function is more important than an air cleaning function. In addition, the axial flow blower blows 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, easy-to-carry, hand-held products are rapidly gaining popularity. An axial flow blower would be suitable for such a handy type humidifying air purifier. In particular, the axial flow blower has a motor and a rotating shaft of the blower at the center of the shaft, so the wind speed is slow. If a cylindrical battery is placed at the center of this axis, it will be possible to miniaturize the battery into a handheld type without reducing the wind speed.

On the other hand, FIG. 6 is an exemplary view showing another embodiment of a filter case and press bar according to a filter of a humidifying air purifier according to the present invention, forming the press bar 137, but wrinkles in contact with the case 130 While pressing the filter 133, bring it 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, respectively. At this time, the pleated filter can be more firmly positioned on the case by the V-shaped pressing protrusion.

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

A plurality of side holes 131e are provided on the side of the case 130, and a collection pad 150 inserted into the side holes 131e and contacting the pleat filter 133 to collect contaminants is further included. can also be configured.

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

In addition, the collection pad may be made of a single material or a composite material among artificial 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 pleat filter, so the concentration of collected contaminants can be high. The collection pad having a high concentration of contaminants can be easily separated from the side hole 131e and discarded.

In addition, since the collection pad is small in size and the irradiation distance of ultraviolet or visible light is short, the effect of sterilizing microorganisms, decomposing contaminants, and drying the collection pad can be maximized even when the output of the light source is low.

253.7nm irradiation is effective for sterilizing microorganisms, and has an effect of preventing quality deterioration of purified air caused by microorganisms.

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

The light source is the main cause of the drying of the collection pad, which serves as a driving force for moving water from the pleat filter to the collection pad, and has the effect of collecting contaminants contained in the water moving to the collection pad.

In addition, the 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 water supply rate decreases as the distance from the wick filter increases and the position increases, so that the filter is dried first. Therefore, it would be efficient to determine the location of the collection pad according to the location of the wick filter, the installation angle of the pleated filter, and the thickness of the pleated filter.

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

The selection of LEDs and lamps capable of irradiating ultraviolet rays or visible rays may be selected according to each feature, but LEDs have advantages in volume, simplicity, service life, power consumption, and the like.

On the other hand, Figure 8 is another embodiment of a case according to the pollution purification filter of the humidifying air purifier according to the present invention, the case is provided with an inner case 130A and an outer case 130B that are disassembled and assembled up and down , The inner case (130A) and the outer case (130B) have a space inside the body and are formed to have a certain length and width, and are formed to have a plurality of connecting teeth (130A-1) (130B-1) each inside, the inner case When the case 130A and the outer case 130B are coupled, the interconnection ribs have a multi-layer structure facing up and down, and the interconnection ribs facing each other may be misaligned.

The outer case 130B may be assembled to the inner case after arbitrarily forming valleys and hills by crossing the pleat filter over the inner case connection ribs 130A-1.

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 cleaned and reused.

Hereinafter, the actions and effects of the humidifying air purifier according to the present invention will be described. The following description follows the above structural description.

Briefly explain the purification process of polluted air using a pleated filter. When the blower is operated and polluted air is introduced, the polluted air passes through the water-soaked mesh of the pleated filter 133, and the contaminants are adsorbed to the water of the mesh.

At this time, the important thing is that in order to increase the removal efficiency of pollutants, the finer the pores of the filter, the better, but the air volume is rapidly reduced.

In order to solve this problem, we tried to solve it with a pleated filter that can increase the filtration area.

In addition, what is important is that only the filter of the mesh is coated with water while preventing the formation of a water film in the pores of the mesh. If an excessive amount of water is supplied to the net, the pores are clogged due to the formation of a water film in the pores, and if a small amount is supplied, the filter dries out and the adsorption efficiency of contaminants drops sharply.

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

In addition, in the present invention, contaminants 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 and used.

The water movement path of the present invention has a clear difference compared to other inventions, so the flow of water will be briefly described. The water in the water supply tank moves to the pleated filter by the capillarity of the wick filter, and after purifying the polluted air while moving in the pleat filter by capillary action or gravity, the water containing contaminants reaches the drying start point. The water containing contaminants that has reached the drying start point evaporates, and the contaminants contained in the water and transported remain at the drying start point and are fixed.

The drying start point is the point at which the supply rate of water and the rate of evaporation of water are the same, and it changes over time. As time passes and the water level in the water supply tank decreases, the drying start point moves toward the wick filter, contaminants are concentrated, and contaminant fixation zones are formed.

What is unusual is that when the water in the water supply tank is replenished or the wind speed of the fan is lowered, the contaminant fixation zone has the variability of moving to the opposite side of the wick filter.

That is, when the change in the water level of the water supply tank and the change in wind speed 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 adhered to the collection pad 150.

Evaporation of water at the drying start point provides direct power to move contaminants from the pleat filter to the drying start point, and is an important factor affecting the lifespan and filtration quality of the pleat filter. In addition, since water evaporates at the drying start point, there is an advantage in that a drainage tank is not required, no leakage occurs, and no wastewater discharged outside the main body.

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 to the pleat filter, minimizes water leakage when carrying or carrying the device, and places the water supply tank at the bottom so that the weight of the device is reduced. An object of the present invention is to provide a humidifying air purifier that has a lowered center of gravity, suppresses the proliferation of microorganisms through rapid water removal and sterilization inside the device, is portable due to its compact size, and is easy to enlarge.

Although the present invention has been shown and described with preferred embodiments as described above, it is not limited to the above embodiments, and to those skilled in the art within the scope of 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.
