Description

Humidifying air purifier {Wet type air purifier}

The present invention relates to a humidifying air purifier, and more specifically, by passing contaminated air through a wet filter in the form of a fine net to adsorb contaminants to the wet filter, washing the adsorbed contaminants with water, and purifying air through a photocatalytic reaction It is about a humidifying air purifier that purifies.

In general, air purifiers for purifying air can be divided into dry air purifiers and wet air purifiers.

The dry air purifier includes a filtration filter type that filters through a HEPA filter/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 rays and the method using plasma have potentially harmful problems to the human body.

In particular, dry air purifiers are heated/dried and dispersed to the upper part, so they must be used indoors with a window closed, and are not suitable for outdoor use because they are weak against moisture.

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

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

The wet filter type passes polluted air through the wet filter, and pollutants are filtered and adsorbed/dissolved in the water film, so the purification efficiency is high. There is a disadvantage in that the wastewater contained therein 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 difficult removal of 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 economic efficiency of purified air is higher than that of the dry air purifier.

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

As a related prior art, in Patent No. 10-2184694 (air cleaning filter using visible light excitation type photocatalyst and manufacturing method thereof), harmful gas decomposition and harmful bacteria are sterilized using a visible light photocatalyst, which can be free from the danger of ultraviolet rays Technology that can do this and remove fine dust is being introduced.

As another prior art, in Patent No. 10-1931444 (wet type air purifier), fine dust from the outside air is adsorbed to the water particles due to collision and friction between the water particles sprayed inside the air purifier and the introduced outside air. 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 vortex was introduced. have.

However, in the prior art, the efficiency of decomposition of harmful gas and removal of fine dust by the visible light photocatalyst alone may be low, the collision of sprayed water particles with air causes high noise, and primary filtering with a HEPA filter and cyclonic swirl flow Contact with water particles can increase the fine dust removal efficiency, but the equipment is large and heavy, and high noise problems may occur.

It is provided above the water surface of the 300 to evaporate and vaporize the water. According to the described structure, there is an effect that the management is very easy by preventing the water from being discharged to the outside of the main body.

In addition, the drain filter 500 includes a pipe-shaped drain filter pipe 520 connected to the wet filter 200 so that the water wetted with the wet filter 200 can move; and the drain filter pipe 520 . and a drain filter fabric 510 extending from the end.

In addition, an axial flow blower 700 for blowing air in the axial direction; and a battery 800 provided in the axial direction of the axial flow blower 700 may be provided in the space.

In addition, the water supply tank 300 has a structure with an open upper surface, and includes a body part filled with water; and a cover part 310 closing the upper surface of the body part; and the cover part 310 ) is a water supply hole into which the water supply filter 400 is fitted; has a structure in which the water supply filter 400 is formed, and the water supply filter 400 includes a first area part 420 provided in the water supply tank 300; and, the first area and a second region portion 410 that is formed to extend from and is exposed to the outside of the water supply tank 300 through the water supply hole of the cover portion 310 and is provided in the space portion, and the end of the second region portion 410 . The addition is connected to the wet filter (200).

According to a preferred embodiment of the present invention shown in Figure 1, the water supply tank is sealed by forming a female screw on the outer wall, and forming and fastening the male screw on the inner wall of the body.

Furthermore, a water supply pipe (not shown) capable of supplying water to the water supply tank may be inserted into the cover part 310 if necessary. In addition, the water supply tank 300 may further include a transparent window (not shown) for checking the amount of water supplied therein.

The wet filter 200 is a key component of the present invention, and the purification process of polluted air using the wet filter 200 will be briefly described. When polluted air is passed through the mesh of a wet filter wet with water, the pollutants are adsorbed and dissolved in the water of the mesh and discharged to the drain filter like water. At this time, it is important that the pores of the net are blocked by the strong surface tension of water to prevent the formation of a water film, and it is preferable that only the filter wire of the net be coated with water. When a water film is formed in the pores, water droplets are scattered, the filtration efficiency is extremely reduced, and a high wind pressure/noise blower is required. Therefore, the present invention is focused on the technology to prevent the formation of a water film on the pores and to allow water to be coated only on the filter wire of the mesh.

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 wet filter by capillary action of the water supply filter, and after purifying the polluted air while moving in the wet filter by capillary action or gravity, the water containing contaminants reaches the drain filter. Water containing contaminants reaching the beginning of the drain filter moves to the end of the drain filter due to gravity and capillary action. At the beginning of the drain filter, the large particle contaminants are filtered first and remain at the beginning of the drain filter, and the water containing the contaminants of small particles passing through is evaporated at the end of the drain filter, and the small particles contained in the water and moved Contaminants remain and adhere to the end of the drain filter.

Evaporation of water at the end of the drain filter provides direct power to move pollutants from the wet filter to the drain filter, and is an important factor affecting the service life and filtration quality of the wet filter. That is, since water is vaporized in the drain filter, there is no need to provide a drain tank, there is an advantage that no leakage occurs, and there is an advantage that there is no wastewater discharged out of the body.

In addition, according to another embodiment of the present invention, one or more partition wall members 910 partitioning the space in the vertical direction; may further include.

The air discharge unit 600 is a blower fan that guides the purified air flowing by the axial flow blower 700 in a preset direction and discharges it to the outside; and an angle control unit that is; and a leak prevention plate 610 that prevents leakage of the purified air.

In addition, preferably, the rim portion of the water supply hole has a structure protruding toward the upper direction.

In addition, the cover part 310 is formed so that the edge is inclined downward toward the edge of the upper surface of the water supply tank (300).

According to another embodiment of the present invention, the water supply tank 300 has a structure that can be opened and closed, and is screwed to the cover portion to prevent decompression generated in the water supply tank by screwing an air hole pipe 330; and , a fixing jaw 320 protruding from the center of the inner bottom surface of the body and fixing the position of the end of the water filter 400 . In the above embodiment, the air hole pipe 330 includes an air hole 331 through which air is introduced, a blocking ball 332 that blocks air inflow when the body is overturned, and the circumference of the air hole tube 330 . A plurality of protrusions are formed along the direction, and a ball passage 333 through which the blocking ball can move; includes.

The air hole 331 prevents the pressure from being applied in the water supply tank, so that water can be smoothly transferred to the wet filter by the water supply filter. Preferably, the diameter is preferably 0.5 mm or less so that the water in the water supply tank does not leak through the air hole 331 when the body is overturned. The blocking ball 332 requires a function to open the air hole 331 during normal operation, and to close the air hole when the body is overturned or overturned. In the air hole closed state, when water is moved from the water supply tank to the water supply filter, the water supply tank is in a decompressed state, so the water supply filter cannot transfer water out of the water supply tank. That is, leakage is prevented.

In addition, the air hole tube 330, a screw groove 334 is formed on the outer peripheral surface so as to be coupled to the cover portion.

When the water supply tank is installed at the bottom of the wet filter, the water supply filter 400 pushes up water to the upper wet filter by capillary action and supplies it, so that there is no problem of excess or shortage of water in the wet filter, preventing the formation of a water film in the pores of the wet filter and can always have moisture in the filter wire. In addition, it is possible to lower the center of gravity of the main body, it is possible to increase the stability of the main body.

3 is a view showing that the wet filter is manufactured in two layers in the humidifying air purifier of the present invention.

Referring to FIG. 3 , the wet filter 200 is sewn in a state in which two layers are spaced apart from each other by a predetermined interval so that evaporation of water is delayed so that water can move to the end of the wet filter, or more than a preset thickness. By sewing thickly to form a water passage in some areas, evaporation of water is delayed.

In addition, according to the embodiment, in a state in which the wet filter frame 220 is positioned at the edge so that the wet filter 200 can be maintained in a flat shape, the wet filter is wound around the wet filter frame and sewn.

In addition, the wet filter 200 and/or the water supply filter 400 and/or the drain filter 500 may be made of one of silk, acetate, cotton, hemp, polyester, nylon, PET, and polypropylene. The wet filter 200 is characterized in that it is made of a material or shape having high moisture absorption.

In addition, the wet filter 200 is characterized in that it is a fabric coated with a photocatalytic material by selecting any one material from among silk, acetate, cotton, hemp, polyester, nylon, PET, and polypropylene.

The photocatalytic material may be selected from any one of titanium oxide (TiO2), zinc oxide (ZnO), zirconium oxide (ZrO2), and tin oxide (SnO2), or a mixture thereof may be used.

The wet filter frame 220 is preferably made of plastic which is light and strong and can maintain the shape of the wet filter 200, but may be made of metal with good elasticity.

Stable water supply to the wet filter 200 maintains a water coating of a certain thickness on the filter wire, thereby preventing the formation of a water film in the pores, securing a water passage, and increasing the effective filtration area of the wet filter.

Stable water supply to the wet filter 200 is important for the inclination of the wet filter.

The slope of the wet filter may be selected according to the maximum height of the water rise of the wet filter from the water level of the water supply tank and the time required to rise. If it is composed of a wet filter made of cotton and raised to 90 degrees, that is, when it is hung and submerged in water, the water rise height/required time is approximately 5cm/1min, 10cm/5min, 12cm/10min, 16cm/30min, 20cm /1 hour, 30 cm/10 hours.

According to the above test results, in the case of a small humidifying air purifier, it is possible to supply water stably to the wet filter even when the rising slope of the wet filter is high, but in the case of a large humidifying air purifier, the rising slope of the wet filter should be low. Considering the moving speed of water and the drying speed of water in a product situation in which the air from the blower passes through the wet filter at a high speed, the lower the slope of the wet filter, the more advantageous it will be for stable water supply.

Accordingly, the other end of the wet filter 200 to which the drain filter 500 is connected is provided to be inclined by 60 degrees upward to 60 degrees downward with respect to the horizontal plane of the wet filter 200 .

4 is a perspective view showing a wet filter press in the humidifying air purifier of the present invention.

In addition, although one water supply filter is shown for one wet filter, a plurality of water supply filters may be provided according to the area of the wet filter.

Supplying water from the water supply tank 300 in which the water supply filter 400 is installed below the wet filter prevents the formation of a water film in the pores of the wet filter 200, and only the filter wire of the mesh can be coated with water. It plays an important role in preventing oversupply and undersupply of water.

In the existing technology of supplying water to the wet filter at the bottom of the water supply tank or to the upper part of the wet filter by a pump from the water supply tank at the bottom, wet Stable water supply to the filter will not be easy.

It further includes a spring 430; According to the structure described above, the second region 410 and the first region 420 are maintained separated from the first region 420 by the force of the spring 430 in normal times, so that even if the body 100 is overturned or overturned, the first region There is an effect that water leakage does not occur from the unit 420 . To explain this in more detail, the end of the first area part 420 in contact with the bottom surface of the water supply tank 300 is not in contact with water or the sealed water supply tank prevents the flow of water to the first area portion even though it is in contact with water. Therefore, there is an effect that leakage does not occur.

In addition, although one drain filter is shown for one wet filter, a plurality of drain filters may be provided depending on the area of the wet filter. The drain filter 500 provides a driving force for continuously supplying fresh water to the wet filter by sucking and evaporating water containing contaminants from the wet filter through capillary action.

In the above 45 degrees, all the ball passages 333 are directed toward the bottom of the water supply tank in the normal operation state, so that the blocking ball opens the air hole, and even if the body falls in any direction, at least one ball passage is the blocking ball 332 . It falls to close the air hole 331 .

The wet filter and the drain filter are made of a material with high water absorption and exhibit a capillary phenomenon, so that water leakage will not occur unless water is separately supplied from the outside. If the water supply tank and the water supply stopper are closely connected, leakage will be prevented. The water supply filter 400 is the same as the situation in which the water supply tank is located at the top during the fall, but if the water supply filter end does not come into contact with water, that is, if the amount of the water supply tank is maintained at 50% or less, leakage will be prevented. In this situation, outside air cannot enter the water supply tank through the water supply filter, so there will be no leakage through the air hole. Also in this situation, the blocking ball will fall and close the air hole. That is, in the humidifying air purifier of the present invention, leakage will be prevented if the tip of the water filter does not come into contact with the water in the water supply tank or if the amount of the water supply tank is maintained at 50% or less. To this end, the water supply tank 300 is characterized in that it is provided with a fixing jaw 320 so that the end of the water supply filter can be located in the center of the bottom of the water supply tank.

9 is an enlarged view showing the operation structure of the binding groove and the binding rod of the discharge part in the humidifying air purifier of the present invention.

9, the angle adjustment unit includes a binding rod 630 into which the blowing fan is rotatably fitted; and a binding groove 620 for fixing the rotation angle of the blowing fan fitted to the binding rod 630, and the and a protrusion 640 for stopping excessive rotation of the blowing fan. The binding rod 630 is easily detachable from the binding groove 620 by the binding rod spring 631 provided in the body. In general, an axial blower is suitable for a place where the wind pressure is relatively small and the flow rate is large, so it is used for a fan.

To explain this in more detail, the blower shown in FIG. 1 shows an axial flow blower 700 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 the slowest wind speed because the motor and rotation shaft of the blower are located in the center of the shaft. If the battery 800 is disposed at the center of the shaft, it will be possible to miniaturize the battery without reducing the wind speed. It will be convenient to use the operation unit 810 of the handy product to be located near the battery 800 .

In contrast, the blower shown in FIG. 2 represents a centrifugal blower 710 suitable for products in which the air purifier function is more important than the humidification function. In addition, the centrifugal blower blows air in the centrifugal direction of the rotating shaft of the blade, so the wind speed is slow and the wind pressure is high, but the volume of the blower is large, so it is mainly used for large products.

2 shows one method of extending the basic module of the humidifying air purifier to upper and lower multi-layers. In this way, the air purification capacity can be greatly increased by extending the upper and lower duplexes to the left and right.

Although the present invention has been described in detail through specific examples, this is intended to describe the present invention in detail, and the present invention is not limited thereto, and by those of ordinary skill in the art within the technical spirit of the present invention. It is clear that the modification or improvement is possible.

All simple modifications and variations of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be clarified by the appended claims.
