2 is a cross-sectional view of the air sterilizer with an air purifying function of the present invention, FIG. 3 is a perspective view of a state in which the reaction tube is inserted into the through hole, FIG. 4 is a lighting state diagram of the concave reflector, and FIG.

As shown, the present invention 'air sterilizer with air purifying function' (hereinafter referred to as 'air sterilizer') has a reaction plate 400, an ultraviolet lamp 410, a concave reflector 411, a convex reflector 412, and a penetrating plate. It includes a ball 420 , a reaction tube 500 , and an activated carbon filter 600 .

The reaction plate 400 is provided in a shape that blocks a predetermined section inside the body 100 .

The through hole 420 is provided in the shape of a through hole passing through the reaction plate 400 in the transverse direction, and the sucked air passes through the through hole 420 .

The reaction tube 500 has a photocatalytic material coated on the outer surface, is inserted into the through hole 420, and has a function to widen the contact area with the passing air, and the reaction tube 500 is damaged or applied. When the function of the photocatalytic material is deteriorated and it is necessary to replace it, it is separated from the through hole 420 and a new reaction tube 500 can be inserted into the through hole 420, so that the function and effect of easy repair and maintenance are provided. have together

The reaction tube 500 includes a body 520 , an inner contact piece 511 , and an outer contact piece 512 .

The body 520 has the shape of a cylindrical tube having a central through hole 510 formed therein.

The inner contact piece 511 has a shape of a straight plate dividing the central through hole 510 on the inner surface of the body 520, so that the introduced air forms a laminar flow while expanding the contact area with the introduced air. .

The external contact piece 512 is provided in the shape of a plate having a curved line on the outer surface of the body 520, and serves to expand the contact area with the introduced air, and discharge the introduced air in a vortex shape.

Since the air passing through the reaction tube 500 as above is in contact with the inner contact piece 511 and the outer contact piece 512, the contact area is maximized. That is, since the contact area between the photocatalyst material applied to the reaction tube and the introduced air is widened, the sterilization effect can be significantly increased.

In addition to this, the air passing through while in contact with the inner contact piece 511 forms a laminar flow, and the air passing through while in contact with the outer contact piece 512 forms a vortex, so that the air passing through the reaction tube 500 forms a vortex. From the last point of the ball, a vortex that rotates regularly and a laminar flow with a constant flow collide, resulting in an irregular mixture of air.

Accordingly, since ozone is prevented from being concentrated in a certain section of air, ozone generated from the low-temperature plasma of the plasma treatment cell 230 can be uniformly distributed in the discharged air.

Therefore, it is possible to maximize the ozone removal effect in the activated carbon filter 600 through which air next passes.

Looking at the operation relationship of the ultraviolet lamp 410 and the concave reflector 411 and the convex reflector 412 as described above,

In this embodiment, when light irradiated from the UV lamp to the reaction tube 500 is irradiated in a state having only a certain path, there is a shaded portion in the reaction tube to solve the problem that the photocatalytic reaction is lowered, Since regular straight light and diffusely reflected light are mixed and irradiated to the reaction tube, the shaded area is minimized, thereby maximizing the function of the photocatalyst.

The activated carbon filter 600 is provided in a shape that blocks the inside of the main body 100 on one side of the ultraviolet lamp 410 in the direction in which air passes through the reaction tube 500, and it can remove ozone by adsorbing ozone. It has a structure in which fibers are woven in the form of fabric fibers to improve the adsorption performance of non-woven fabrics or activated carbon containing activated carbon.

As shown, the filter unit 200 includes a filter case 210 , a filtering net 211 , a coupling hole 730 , a cartridge 740 , a 'first filter 220 , a plasma treatment cell 230 , and a second Filter 240 ' (hereinafter referred to as 'filter'), includes a detachable means (700).

The filter case 210 has a rectangular box shape, and a coupling hole 730 is formed on one side thereof, so that the filter of the cartridge 740 to be described later is fitted and coupled.

The filtering net 211 is provided in the front and rear through holes of the filter case 210, and functions to filter large particles of dust.

The cartridge 740 is provided in a shape in which the filter protrudes from one side, so that the filter can be attached to and detached from the coupling hole 730 formed in the filter case 210 .

The hinge shaft 760 is provided in a state coupled to one side of the bracket protruding from the upper and lower surfaces of the cartridge 740 and the hook 710, and enables the hook to perform seesaw motion.

Looking at the operating relationship of the attachment/detachment means of the air filter having the above structure,

When the filter is coupled to the filter case 210 of the air sterilizer, when the user presses the hook 710, the hook 710 overcomes the elastic force of the elastic body 750 due to the pressing pressure and maintains a horizontal state. In this state, the user inserts the filter of the cartridge 740 into the coupling hole 730 of the housing 210 , and releases the pressure of the hook 710 .

When the pressing of the hook is released, the hook rotates like a seesaw motion with the hinge shaft 760 as a point by the elastic force of the elastic body 750, and the rotated hook is caught on the engaging jaw 721 of the fastening hole, The cartridge can be easily attached to the filter case.

The cartridge can be easily separated from the filter case by performing the above coupling sequence in the opposite direction.

Hereinafter, an embodiment capable of attenuating vibration and noise that may occur in the detachable means will be described.

The cartridge 740 fastened by the detachable means 700 may generate noise by vibration generated during the operation of the air sterilizer, and this embodiment will describe a configuration that can minimize the noise.

Since the noise of the detachable means is generated most at the contact portion between the hook 710 and the locking jaw 721, in this embodiment, the locking jaw 721 is coated with a rubber composition for damping vibration.

The rubber composition is based on 100 parts by weight of the acrylic rubber, 10 to 20 parts by weight of carbon black having a particle size of 20 to 45 (nm), 5 to 7 parts by weight of an accelerator, 4 to 5 parts by weight of an activator, 1 to 4 parts by weight of an antioxidant , 4 to 5 parts by weight of a vulcanization aid, 3 to 7 parts by weight of a peroxide crosslinking agent, and 3 to 6 parts by weight of paraffin oil.

The rubber composition as described above has excellent mechanical properties such as tensile strength and permanent compression set in addition to high heat resistance, minimizes natural frequency change at high temperature, improves durability, and has excellent vibration damping performance.

Hereinafter, a low-temperature plasma applied to a plasma processing cell will be described.

The sterilization technology using plasma can effectively sterilize the object without high-temperature heat treatment unlike the existing sterilization method, but it requires a high-voltage power supply, and the high-voltage power supply requires high cost and a large space over a certain size. High safety is required because high voltage is used.

Therefore, since it is difficult to provide a high-voltage plasma generating device in a general household, the present embodiment intends to provide a configuration capable of sterilizing air using low-temperature plasma.

As shown, the plasma processing cell 230 includes a first dielectric barrier discharge electrode 231 made of a conductive metal thin film, a dielectric barrier layer 232 stacked on the first dielectric barrier discharge electrode 231, and a predetermined interval. and a second dielectric barrier discharge electrode 233 made of a perforated conductive metal thin film.

The second dielectric barrier discharge electrode 233 of the conductive metal thin film is stacked on the dielectric barrier layer 232, and a portion of the surface of the dielectric barrier layer 232 is perforated with a predetermined size and spacing so as to be exposed to the atmosphere. .

And when the perforated second dielectric barrier discharge electrode 233 is used as a ground electrode, and power is applied to the first dielectric barrier discharge electrode 231 through the coaxial cable 234, each of the holes exposed to the air Atmospheric pressure plasma is generated at the dielectric barrier surface.

The generation of such plasma is accompanied by emission of ultraviolet rays, and since various active species ions can be generated and diffused, pasteurization and disinfection of the incoming air is performed by ultraviolet rays and active species ions.

The dielectric barrier layer 232 may be made of a single layer selected from various dielectric materials such as glass, quartz, ceramic, enamel, mica, plastic, silicone rubber, PET, Teflon, and PDMS.

Alternatively, the dielectric barrier layer 232 may be manufactured in the form of a composite material in which various metal oxide catalysts (TiO2, ZnO, MgO, etc.) powder and activated carbon powder are coated on a dielectric material layer.

When the metal oxide catalyst is distributed on the surface of the dielectric barrier layer, the generation of the same reactive oxygen species can be promoted when plasma is generated, and the sterilization and detoxification effects of the air introduced by the active oxygen species are further increased.

Hereinafter, an embodiment of a vibration-proof structure capable of attenuating vibration generated by a blower fan of an air sterilizer will be described.

When the injection of air is completed, of course, the stopper is closed.

If we look at the operation relationship of the anti-vibration part fastened as above,

The vibration generated by the blower fan 320 is transmitted to the bottom plate, and the vibration of the bottom plate is transmitted to the rubber film 820 .

The vibration transmitted to the rubber film 820 is further attenuated by the elastic restoring force of the air pressure inside the rubber film and the elastic restoring force of the springs provided on the upper, lower, and side surfaces of the rubber film inner partition.

The elastic piece 941 is installed with one side fixed to the upper surface of the step 943, and by the elastic piece opening or closing the opening 942, the air of the vacuum unit 910 is discharged or sucked to the outside. function.

The wire 945 is fixed to the upper surface of the elastic piece 941 and is installed in a state drawn out of the opening.

The handle 944 is provided at the end of the wire 945, and the user grips and pulls it, and bends the elastic piece, thereby communicating the opening with the outside air and has a function of opening.

Looking at the operation relationship of the adsorption fixing unit 900 as described above,

When the user places the stationary air sterilizer at the place where the user wants to fix it, that is, at the suction or discharge port of the air conditioner and presses the stationary air sterilizer, the body 930 of the elastic material adsorption fixing part 900 is compressed while the vacuum part 910 is pressed. As the air is discharged to the outside by placing the elastic piece 941 through the opening 942, a negative pressure is formed in the vacuum unit.

When a negative pressure is formed in the vacuum unit in this way, the elastic piece 941 closes the opening 942 due to the pressure of the external air, and since the negative pressure is maintained in the vacuum unit, the stationary air sterilizer is fixed to the air conditioner by the external air pressure. can do it

When the user wants to separate the stationary air sterilizer from a fixed place, when the user grabs the handle 944 and pulls it, the elastic piece 941 is bent upward by the wire 945 connected to the handle, and the opening 942 opens to outside air. In communication with the, external air is sucked into the vacuum unit (910).

Therefore, since the vacuum unit loses the negative pressure and the adsorption force is eliminated, the stationary air sterilizer can be separated from the air conditioner.
