Description

FIELD OF THE INVENTION [0001] The present invention relates to an air sterilizing apparatus for generating and discharging hydroxyl radicals usable in an indoor environment,

The present invention relates to an air sterilizing apparatus, and more particularly, to an air sterilizer for generating and discharging hydroxyl radicals in an indoor environment of a home or a vehicle.

Hydroxyl radicals are widely used as air disinfectants in indoor environments such as hospitals or homes. The germicidal properties of hydroxyl radicals were known in the early 1960s by Porton Down in the UK and TNO in the Netherlands. Airborne sterilization using hydroxyl radicals or the like is naturally occurring in the external environment, but the natural sterilization effect is extremely reduced in the indoor environment where it is difficult to ventilate with the outside.

As an example for providing the sterilization function of hydroxyl radicals indoors, an apparatus for generating hydroxyl radicals as an air-based sterilizing agent has been developed in International Patent Publication No. WO2005 / 026044. Here, by supplying ozone together with an olefin such as terpene or the like, a reactant gas is reacted with ozone to generate a hydroxyl radical.

The above-mentioned hydroxyl radical generating apparatus is based on the use of ozone. Ozone forms an ozone layer that absorbs ultraviolet light from outside the atmosphere, but forms smog harmful to the human body by photochemical reactions on the surface. Therefore, when the hydroxyl radical discharging apparatus is used, the unreacted ozone that has not participated in the reaction is liable to cause environmental pollution if it is discharged into the indoor environment.

In addition, it is necessary to miniaturize the device so that it can be easily carried by a general user in an indoor environment of a home or a vehicle. In order to perform safe sterilization of air in a tightly sealed space, it is necessary to maximize the rate of production of ozone from the introduced air, and at the same time, the reaction between the ozone and the reactant gas is uniformly performed, .

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and similarities. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

The basic chemical reactions that generate hydroxyl radicals are already known, and theoretically, the content ratio of ozone and reactant gases that meet the optimal hydroxyl radical production conditions can be obtained. In addition, the ozone generation rate can be controlled to some extent by controlling the voltage supplied to the ozone generator. However, it is practically impossible to precisely control and supply the content of ozone and reactant gas to meet the theoretical optimum conditions. Therefore, in designing and manufacturing a small-sized apparatus for use in a home or a vehicle, it is difficult to originally block the discharge of residual ozone not participating in the reaction.

Rather, the inventors of the present invention have found that, owing to various experiments, the major cause of the discharge of residual ozone not participating in the reaction is that the ozone and the reactant gas can not be uniformly mixed in the mixing chamber. Thus, the inventors of the present invention have found that while the air sterilizing apparatus for generating and discharging hydroxyl radicals can be made compact so as to be easy to carry by the user, the ozone and reactant gas can be uniformly reacted, The air sterilizing device capable of effectively preventing the remaining amount of ozone from being discharged into the room has been designed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an air sterilizer according to the present invention. FIG. 2 is a sectional view of the inside of the air sterilizer according to the present invention, And FIG. 3 is a schematic cross-sectional view schematically showing an arrangement state of major components. 1 to 3, an internal structure of the air sterilizing apparatus according to the present invention will be described as follows.

The air sterilizing apparatus according to the present invention includes a case 100 having a hollow formed therein, an inlet 110 through which air is introduced into a side surface, and an outlet 120 through which hydroxyl radicals are discharged. Here, the case 100 may include an upper case 101, a center case 103, and a lower case 102, wherein the cases 101 to 103 are formed separately from each other, Can be engaged by fitting. Particularly, a plurality of through holes are formed along the outer edge of the center case 103, and the through holes serve as an inlet 110 into which the outside air A1 flows into a hollow space formed inside the case assembly. Further, an opening is provided at the upper end of the upper case 101, and this opening functions as an outlet 120 through which the hydroxyl radical generated in the air sterilizing apparatus according to the present invention is discharged. In this embodiment, an example in which the case is formed of three parts is exemplified, but it may be constituted by one or two cases for convenience of assembly or disassembly.

Ozone chamber housings 201 and 202 constituting an ozone chamber are disposed inside the case. The ozone chamber housings 201 and 202 are preferably disposed under the case. The upper housing 201 and the lower housing 202 can be formed to be fastened and detachable to each other. A plurality of through holes 210 are formed in the upper surface of the upper housing 201. A concave space (hereinafter referred to as " concave ") is formed by fastening the upper and lower housings 201 and 202. The air introduced from the through- It is preferable that the side and bottom portions are formed as close as possible so that they can remain. The upper and lower housings 201 and 202 may be formed of a material that shields an arc discharge generated in the ozone generator 220. For example, the ozone chamber housings 201 and 202 may be formed of an insulating synthetic resin material.

The ozone chamber 200 has a structure in which air is introduced through the through hole 210 formed in the upper part and the ozone generated by the ozone generator 220 is discharged through the through hole 210. That is, since only one side of the ozone chamber 200 is opened by the through-hole 210, the air introduced into the through-hole 210 remains in the concave portion for a sufficient time, The efficiency of ozone generation through the arc discharge can be maximized. Here, as the ozone generator 220, for example, an electric drive ozone generator such as a corona discharge ozone generator may be used, and preferably an ozone generator for ionizing air. In addition, the ozone generator can function as an ionizer capable of generating negative ions.

The cartridge 300 is disposed on the upper part of the ozone chamber 200. The cartridge 300 is internally provided with a reactant that reacts with ozone to supply a reactant gas that produces hydroxyl radicals. Here, the reactant is vaporized by natural evaporation or the like, discharged to the outside of the cartridge 300, and then reacted with ozone to generate a hydroxyl radical, for example, hydrogen peroxide water (H ₂ O ₂ ) or an olefin Olefin) may be used. Suitable olefins include Terpentine, Alpha-Terpinene, Gamma-Terpinene, Delta-Limonene, Myrcene, Pentene, Cyclohexene, butene, and the like.

It is preferable that the cartridge 300 is installed so that the user can exchange it. The cartridge 300 is preferably disposed inside the central bracket 400 disposed on the ozone chamber 200. Particularly, in the central bracket 400, the air A1 introduced from the inlet 110 is guided to the ozone chamber 200, and the ozone formed in the ozone chamber 200 passes through the side wall of the cartridge 300, It is preferable that a guide for inducing the flow to the edge of the surface portion 501 is formed. That is, a first guide piece 401 may be formed at the edge of the center bracket 400 to allow the introduced air to flow into the ozone chamber 200 disposed at the lower portion. A second guide piece 402 may be formed to extend downward from the inner wall of the case 100 with a predetermined gap therebetween. In particular, the second guide piece 402 is preferably formed to be spaced apart from the side wall of the cartridge 300 disposed inside the center bracket 400. The passage formed by the second guide piece 402 and the side wall of the cartridge 300 functions as a channel through which the ozone generated in the ozone chamber 200 flows into the mixing chamber 500.

Meanwhile, the mixing chamber 500 is provided through a mixing chamber housing 510 disposed on the central bracket 400. Here, the mixing chamber 500 functions as a space in which the ozone introduced from the ozone chamber 200 and the reactant gas evaporated from the cartridge 300 are mixed with each other to cause a reaction. More specifically, the mixing chamber 500 includes an inlet surface portion 501 through which ozone and reactant gas flow, an outlet surface portion 502 for discharging the ozone and the hydroxyl radical generated by the reaction of the reactant gas into the outlet 120 And a reaction space 503 in which a side surface excluding the inflow surface portion 501 and the discharge surface portion 502 is sealed. That is, the mixing chamber 500 can be formed in a tubular shape having both ends thereof opened. An opening surface connected to the center bracket 400 side is defined as an inflow surface portion 501, And an outlet face portion 502 connected to the outlet 120 side.

Particularly, the reaction space portion 503 is preferably formed symmetrically with respect to at least one virtual plane including an axis C connecting the center of the inlet surface portion 501 and the center of the outlet surface portion 502 . That is, the virtual plane may be a plane including the axis C shown in Fig. 3, and may be a plane perpendicular to the plane of Fig. 3 including the axis C, for example. At this time, the upper surface of the cartridge 300 is disposed at the center of the inlet surface portion 501, and the reactant gas B flows into the reaction space portion 503. The ozone generated in the ozone chamber 200 flows into the reaction space portion 503 through the edge of the inflow surface portion 501 through the side wall of the cartridge 300. The mixing chamber housing 510 is provided with a mounting hole 511 which can be fastened to the upper portion of the cartridge 300 at the center of the inlet surface portion 501 and a plurality of air- (512).

Meanwhile, as another embodiment, the space formed by the reaction space portion 503 may be divided by at least one diaphragm formed with a plurality of openings. For example, as shown in FIG. 6, the reaction space portion 503 may be divided into a plurality of spaces by the first diaphragm 520 and the second diaphragm 530. By dividing the reaction space 503 into a plurality of spaces, mixing of ozone and reactant gas can be induced more smoothly. In particular, the first diaphragm 520 and the second diaphragm 530 are preferably formed perpendicular to the axis C, respectively. The first diaphragm 520 is formed to cover the inlet surface portion 501. Ozone flowing through the reactant gas and the vent hole 512 flowing from the outlet 330 of the cutridge 300 flows into the first diaphragm 520, and then discharged through the first opening 521. In this case, In addition, the second diaphragm 530 is formed to cover the first opening 521. The ozone and the reactant gas which are not reacted with each other in the space formed by the first diaphragm 520 can be mixed in the space formed by the second diaphragm 530 so that the remaining amount of unreacted ozone and reactant gas can be minimized have.

Particularly, the first diaphragm 520 and the second diaphragm 530 are preferably formed perpendicular to the axis C, and furthermore, the first opening 521 and the second opening 531 are formed to have an axis C And is formed symmetrically with respect to at least one virtual plane including the virtual plane. Furthermore, it is more preferable that the first opening 521 and the second opening 531 are arranged so as not to overlap with each other on a vertical line with respect to the axis C as a reference. This arrangement causes a vortex to form in each of the space formed by the first diaphragm 520 and the space formed by the second diaphragm 530 with the pressure sucked by the fan. Therefore, the ozone and the reactant gas can be mixed more smoothly to maximize the hydroxyl radical generation rate, and at the same time, the unreacted ozone residual amount can be minimized.

The cartridge 300 is provided with a discharge port 330 on the upper surface thereof and a membrane 320 for allowing the reactant gas B discharged from the reactant 310 to pass therethrough and discharged to the outside do. Here, the membrane 320 may be a synthetic resin such as PET (polyethylene terephthalate), PE (polyethylene), porous Teflon, or the like, which is an air permeable film capable of selectively passing only gas without passing through liquid.

Next, a circuit for driving the air sterilizing apparatus according to the present invention will be described with reference to FIGS. 2 and 4. FIG.

First, a power supply circuit portion 610 for supplying a power source inputted through the power supply terminal 611 to each circuit member is disposed under the ozone chamber 200. The high voltage circuit portion 620 is disposed so as to be spaced apart from the power supply circuit portion 610 by a predetermined distance. Here, the power supply circuit portion 610 and the high voltage circuit portion 620 may be provided as separate PCBs. The PCBs constituting the power supply circuit unit 610 and the PCBs constituting the high voltage circuit unit 620 are preferably spaced apart from each other at predetermined intervals in order to avoid electrical interference due to the generation of high voltage. In addition, the high voltage circuit unit 620 supplies a high voltage to the ozone generator 220 disposed in the ozone chamber 200. As described above, the ozone chamber 200 is formed in a closed structure on the side and the bottom to shield the arc discharge generated in the ozone generator 220, and the high voltage circuit unit 620 disposed below the ozone chamber 200, The supply circuit portion 610 can be prevented from being damaged by the arc discharge.

On the other hand, a cartridge mounting sensor 630 can be disposed adjacent to the cartridge 300, thereby identifying whether or not the cartridge 300 is mounted. When the cartridge 300 is not mounted, reaction of the reactant gas and ozone does not occur, so that the ozone generated in the ozone generator 220 can be directly discharged to the outside. In this case, environmental pollution by ozone may be caused. The cartridge mounting sensor 630 prevents electric power supplied to the high voltage circuit unit 620 from being automatically cut off when the cartridge 300 is not mounted so that unreacted ozone is prevented from being discharged to the outside as it is .

A control circuit unit 640 connected to a switch 642 for allowing the user to control the apparatus is disposed above the case 100. The control circuit unit 640 drives the power supply circuit unit 610, the fan module 650, and the LED display unit 641 when the user turns on the apparatus. The LED display unit 641 notifies the user that the device is in use state, and improves the aesthetics of the device appearance. In addition, the fan module 650 is disposed on the upper side of the case 100, and disposed on the discharge surface portion 503 side of the mixing chamber 500. It is preferable that the fan module 650 is installed at the edge of the case 100 via a buffering member (not shown) that absorbs vibration.

The structures and the circuit members constituting the air sterilizing apparatus according to the present invention are designed such that the volume of the air sterilizing apparatus can be minimized while at the same time maximizing the production efficiency of hydroxyl radicals. Particularly, in order to maximize the reaction efficiency of the ozone and the reactant gas, the ozone and the reactant gas introduced into the mixing chamber 500 must be uniformly distributed to one side. When the flow rate of the air containing ozone flowing into the reaction space portion 503 of the mixing chamber 500 is not uniform or the region where the ozone and the reactant gas are mixed is biased to one side in the reaction space portion 503, The ozone that has not participated in the reaction is discharged to the outside, which can cause environmental pollution.

The air sterilization apparatus according to the present invention formed with the above-described structure can uniformly mix ozone and reactant gas introduced into the mixing chamber 500, thereby minimizing the amount of ozone generated in the ozone generator 200, And a constant amount of hydroxyl radicals is always generated and discharged. That is, the reactant gas B flows in the central portion of the inlet surface portion 501 of the mixing chamber 500 through the outlet of the upper portion of the cartridge 300, and the air A2 containing ozone at the edge of the inlet surface portion 501 So that the reactant gas and ozone can always be uniformly mixed. The ozone generated in the ozone chamber 200 flows into the reaction space portion 503 through a channel composed of the center bracket 400 and the side wall of the cartridge 300. The ozone chamber 503 has a center The ozone introduced into the reaction space 503 can be uniformly mixed with the reactant gas.

The center of the ozone chamber 200 and the center of the cartridge 300 are substantially coincident with the axis C so that the ozone inlet path and the reactant gas inlet path of the mixing chamber 500 are symmetrical with each other. . Also, it is preferable that the ozone chamber 200 and the cartridge 300 are arranged symmetrically with respect to at least one virtual plane including the axis C. 5, the through hole 210 formed in the ozone chamber 200 is preferably formed to be symmetrical with respect to at least one imaginary plane including the axis C, as shown in FIG. It is also preferable that the discharge port 330 formed in the cartridge 300 is arranged to substantially coincide with the axis C. [ In addition, it is preferable that the center of the fan 650 disposed on the side of the discharge surface portion 502 is arranged to substantially coincide with the axis C.

If the flow rate of the air flowing into the ozone chamber 200 is too fast, the rate of generation of ozone by the ozone generator 220 is reduced. The ozone chamber 200 according to the present invention is formed such that the air introduced by the concave portions provided by the upper and lower housings 201 and 202 remains for a predetermined time. That is, as shown in FIG. 5, since the through hole 210 is formed on one side of the upper surface of the ozone chamber 200, the flow of air inside the concave portion is not fast. This structure can maximize the rate of ozone generation. The through hole 210 is formed in the shape of a sleeve 211 protruding outward so that the user can change the position of the needle electrode 220 of the ozone generator 220 disposed inside the ozone chamber 200, (221) is prevented from being damaged.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. It is therefore to be understood that the embodiments of the invention described herein are to be considered in all respects as illustrative and not restrictive, and the scope of the invention is indicated by the appended claims rather than by the foregoing description, Should be interpreted as being included in.
