Each of these general air purifying or sterilizing methods includes an air purifier using a filter, an air purifier using water, an air purifier using plasma (discharge), an air purifier using a catalyst, an air purifier using ultraviolet rays, and ozone. Used air purifiers;

As an example, Korean Utility Model Registration No. 20-0376054 discloses, in an air purifier having a dust collecting filter 40, a cylindrical body 10 having air inlet and outlet ports 16a and 16b, and the body ( 10) and the rotary blade 20 is installed inside the forcing the flow of air. A driving device connected to the shaft 22 end of the rotary blade 20 to rotate the rotary blade 20, and a plurality of UV lamps that are installed inside the body 10 and external to the rotary blade 20. 30 and a current supply device for supplying current to the driving device and the UV lamp 30, by coating a photocatalytic material (t) on the inner wall surface of the passage and the surface of the rotary blade 20 Proposed air purifier.

However, the air purification method using the filter provided in most air purifiers, including the patent literature, has the advantage of excellent filtering ability of dust, bacteria, organic matters, etc. In addition to the inconvenience of frequent replacement, there is a problem in that the maintenance cost according to the filter purchase.

Moreover, if the filter is continuously used beyond the processing capacity, there is a fatal disadvantage that the filter is contaminated with various bacteria and contaminated air is discharged while passing through the filter.

Accordingly, the patent document further includes a photocatalyst device in addition to sterilization by an ultraviolet lamp in addition to the dust collecting filter, and has a rotary blade for extending the contact time between the ultraviolet lamp and the air.

However, in the case of using the dust collecting filter, the air flow is suppressed along with the problems described above, and a considerable time is required to purify the entire air in the room, while the bacteria that are filtered out of the dust collecting filter remain as it is, which may worsen the air in the room. There is.

In addition, although the patent document sterilizes using an ultraviolet lamp, the bacteria are completely sterilized after being treated for several minutes to several tens of minutes, although the patent document actually increases the residence time of air by rotating blades. The air residence time in the space is only a few seconds to several tens of seconds, so the sterilization ability by the ultraviolet lamp is inevitable with this structure.

An object of the present invention for solving the problems of the prior art, it is possible to effectively collect the dust, bacteria, organic matters, etc. in the indoor air without restraining the flow of air, furthermore can completely sterilize the collected bacteria Of course, it is possible to purify a large amount of air in a short time to provide an air sterilization purifier that maximizes the purification capacity and purification efficiency.

The present invention for achieving the above object, the water 220 is stored and the water tank 200 is equipped with a mist pump 210 therein; A space is formed therein, a water movement through hole 101 is formed at a lower end thereof, and an air inlet 102 is formed at a bottom thereof so that the lower part is submerged in the water tank 200; An element mounted in the inner space of the case includes a plurality of ultraviolet lamps 110 installed on the suction port 102, a photocatalyst layer 130 provided on the ultraviolet lamps, and a blower 140 installed on the case. And, between the ultraviolet lamp 110 and the tank is characterized in that the open.

According to the present invention, it is a structure that filters dust, bacteria, and organic matters in the air by fog without applying a filter, so that the air flows smoothly, so that a large amount of air can be purified in a short time, and the air resistance is minimized. Reduces power consumption and generates little noise.

In addition, since the UV lamp and the water tank are open, various harmful bacteria collected by the fog are collected in the water stored in the water tank and exposed to UV light for a long time, and also the treatment by the fog, the treatment by the UV and ozone, the photocatalyst treatment, etc. It is excellent in sterilization and organic decomposition ability with multiple sterilization and decomposition treatment.

In addition, the vortex plate installed between the ultraviolet lamps generate vortices in the flow of air without a separate electric drive, the electricity consumption is reduced, as well as the air is exposed to ultraviolet light for a long time has the advantage of double the sterilization capacity.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

1 is a block diagram showing the internal structure of the air purifier according to the present invention, as shown in Figure 1, the air sterilization purifier of the present invention is provided with a water tank 200 in which water 220 is stored, the water tank A mist pump 210 for generating a fine mist 221 using the water 220 is formed inside the 200, and a water level sensor 230 for detecting whether the water is at an appropriate level.

The water level sensor 230 detects when the water is lower than the appropriate level, and stops the operation of the fog pump 210 to prevent overheating of the fog pump and unnecessary power consumption.

Although not shown, the appropriate level indicator means (for example, a display line or a ball) may be formed in the water tank 200 so as not to exceed the proper level when the water 220 is replaced or refilled. Appropriate height is preferably installed at 100mm or less from the bottom surface of the water tank 200, which is enough to the bottom surface of the water tank 200 through the water 220 is ultraviolet light irradiated from the ultraviolet lamp 110 as described below This is to allow the incident.

The case 100 installed in the water tank 200 is provided with a through hole 101 for allowing the water 220 to flow into a lower end thereof, and an inlet 102 for sucking air is installed at a bottom thereof. The inlet 102 may be installed at a position higher than the water level of the water 220.

In addition, a plurality of ultraviolet lamps 110 connected to the stabilizer 111 are stacked in the case 100, and a vortex is formed while air flows between the plurality of ultraviolet lamps 110 to delay the flow rate. The vortex plate 120 may be installed, and the photocatalyst layer 130 coated with titanium dioxide is provided on the ultraviolet lamp 110.

In addition, a blower 140 is installed at the top of the case 100 to discharge the air introduced through the inlet 102 to the outside.

2 is a plan view of the vortex plate according to the present invention, Figure 3 is a partial enlarged view showing a cross-sectional view of the vortex plate according to the present invention, the vortex plate 120 has a fine vertical hole 121 is formed inside the plan view In this case, in order for the vortex to occur while the air passes through the vertical hole 121, the wall surface of the vertical hole 121 and the upper surface 122 of the vortex plate 120 are formed at right angles to each other as shown in FIG. Is preferred.

This is because the friction occurs while contacting the wall surface while passing through the narrow vertical hole 121, which is a limited space of air, and the flow rate is slowed down, due to the rapid speed and pressure difference as the friction force is removed. Vortex occurs while swirling, because if the vertical hole 121 wall surface and the top surface 122 has a gentle slope, sufficient vortex does not occur.

4 is a plan view of a photocatalyst plate according to the present invention, wherein the photocatalyst layer 130 has a plurality of photocatalyst plates 131 formed in a plurality of layers, and the photocatalyst plate 131 has a net-shaped frame therein. 132 is formed.

Referring to FIG. 4, the frame 132 has a horizontal and vertical lattice shape, and a diagonal sloping frame 132 which is inclined in the horizontal and vertical directions may be sufficiently in contact with the air without disturbing the flow of the air. It is formed in the form, the titanium dioxide film is formed on the outer surface to act as a photocatalyst by receiving light emitted from the ultraviolet lamp 110.

Hereinafter, the operation of the air sterilizing purifier of the present invention will be described with reference to FIG. 1, and the configuration of the present invention will be clearer through this.

As shown in FIG. 1, when power is applied while the water 220 is stored in the water tank 200, the ultraviolet lamp 110 inside the case 100 is turned on and the blower 140 is driven at the same time. As the fog pump 210 in the water tank 200 operates to generate the fog 221, the fog 221 is formed around the inlet 102, that is, the space below the inner side of the case 100 as shown in the drawing.

At this time, the air in the room is introduced into the casing 100 through the inlet 102 by driving the blower 140, and the introduced air is mixed with the mist 221 while the dust, bacteria, organic matter in the air is mist The particles are collected by the particles and fall into the water 220 stored in the water tank 200.

As such, the present invention does not interfere with the flow of air by filtering organic matter, dust, and bacteria in the air by using fog without using a filter, and the collected dust, bacteria, and the like are not included in the water 220 of the tank 200. It is contained inside and can be stored for a long time.

As such, the primary purified air moves upward by the suction force of the blower 140 and passes through the region in which the ultraviolet lamp 110 is installed.

Ultraviolet rays irradiated from the ultraviolet lamp 110 and ozone generated by the ultraviolet rays are continuously incident to the water 220 in the tank and irradiated to the bacteria collected in the water 220, and the ultraviolet exposure time is at least several tens of minutes to several minutes. Full sterilization is possible because of time exposure. At this time, the water 220 in the water tank 200 in consideration of the UV transmittance of water is preferably maintained at 100mm or less from the bottom, if the water level is 100mm or less, ultraviolet light can be sufficiently incident to the bottom of the water tank 200.

On the other hand, the air rising through the region in which the mist 221 is formed passes through the region of the ultraviolet lamp 110, and in this process, residual bacteria and organic matter in the air that are not collected by the mist 221 are formed in the plurality of ultraviolet lamps 110. Sterilization is carried out by ultraviolet rays irradiated at) and ozone generated by ultraviolet rays.

In this process, the vortex plate 120 interposed between the UV lamps 110 is sterilized more effectively by delaying the flow of air in the UV lamp 110 region, and the vertical hole 121 formed in the vortex plate 120. The size of the air does not impede the flow of air, while the vortex plate 120 is made of a metal material that can reflect the light emitted from the ultraviolet lamp 110 by smoothing the surface, such as stainless steel, air It is desirable to allow more exposure to ultraviolet light.

On the other hand, ozone generated by ultraviolet rays sterilizes bacteria in the air and effectively decomposes organic matters, but removes ozone in the air remaining in the case 100 because it damages the human body when discharged into the room as it is through the blower 140. Needs to be.

To this end, if the photocatalyst layer 130 is installed below the blower 140, ozone in the air passing through the photocatalytic layer 130 is decomposed and converted into beneficial oxygen and discharged into the room, which is not only more beneficial to the human body, but also the ultraviolet ray. In the lamp 110 region, untreated bacteria and organics are sterilized and decomposed by a photocatalytic effect of ultraviolet rays.

In addition, the photocatalyst layer 130 is converted into oxygen beneficial to the human body by the photocatalytic action, even if the fine water particles of the mist generated in the mist pump 210 by the blower 140, discharged from the blower 140 The air that is released releases a large amount of oxygen to make the indoor air comfortable.
