Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components are omitted. And, it should be understood that the present invention may be embodied in many different forms and is not limited to the described embodiments.

The present invention relates to an air sterilization and purification device, and as shown in FIGS. 3 to 8, the configuration is a case 100 and a sterilization and purification unit formed on the inner upper portion of the case 100 to sterilize and purify incoming air ( 200) and the discharge unit 300 formed on the inner lower part of the case 100 to discharge the air purified by the sterilization and purification unit 200 to the outside and the sterilization and purification unit installed on the case 100 ( 200) and a control unit 400 that controls the operation of the discharge unit 300.

Here, a motion detection sensor 440 may be further installed in the lower part of the control unit 400 to be exposed to the outside. When a person's motion is detected through the information, the sterilization and purification unit 200 and the discharge unit 300 are operated.

Therefore, it is possible to reduce energy waste by normally being in a standby state and operating only when a human motion is detected in an adjacent distance.

At this time, the air sterilization and purification device of the present invention may be installed indoors and used, but may also be installed and used outdoors by using a separate clamp (not shown) on a crosswalk, parasol, parago, playground, etc.

Of course, the air sterilization and purification device of the present invention can be installed as a built-in on the cover of large machine tools or industrial facilities, as well as the above-mentioned use, and can be attached to the inside of the cover with a fixing bracket to prevent friction and molding of metals caused by the operation of the machine. It can also be used to reduce air pollutants that may be generated by the process.

In addition, the sterilization and purification unit 200 and the discharge unit 300 are formed as separate spaces, and the sterilization and purification unit 200 includes a filter unit 210 that filters foreign substances included in the inflowing air and the filter unit A purifying space 230 installed at the rear of the purifying space 230 to purify harmful substances contained in the air and a sterilization space 240 installed at the rear of the purifying space 230 to sterilize bacteria and viruses contained in the air. It can be done.

Here, the filter unit 210 includes a first filter 212 that primarily filters foreign substances included in the air introduced through the inlet 112 of the front cover 110 and a rear portion of the first filter 212. It may be made of a second filter 214 that is installed on and filters finer foreign substances.

Foreign matter can be removed more completely.

Meanwhile, a photocatalyst filter 232 may be installed in the center of the purification space 230, and UVA LEDs 234 for irradiating UVA light to the photocatalyst filter 232 are installed on both sides of the photocatalyst filter 232. However, the photocatalytic filter 232 may be installed to be replaceable inside a guide 233 provided in the center of the purification space 230 .

Here, when the ultraviolet light irradiated from the UVA LED 234 reacts with the photocatalytic filter 232, active oxygen is generated, and this active oxygen decomposes organic compounds such as various formaldehyde and VOCs included in fine dust. As a result, fine dust is significantly reduced.

At this time, a UVC LED 242 for irradiating UVC light may be installed on one side or both sides of the sterilization space 240 located at the rear of the purification space 230. Ultraviolet rays sterilize bacteria and viruses contained in the air.

Therefore, by first physically removing foreign substances through the filter unit 210, chemically decomposing foreign substances through the purification space 230, and sterilizing bacteria and viruses through the sterilization space 240, It becomes possible to sterilize and purify the air more completely.

In addition, a first blocking wall 252 may be installed between the sterilization space 240 and the purification space 230, and the sterilization space 240 and the purification space 230 ) is divided into separate spaces.

Here, a first through hole 254 may be formed in the lower part of the first blocking wall 252, and the air purified through the purification space 230 by the first through hole 254 passes through the sterilization space ( 240).

On the other hand, a second blocking wall 256 having a second through hole 258 formed therein may be formed at the rear of the first blocking wall 252, and the sterilization space is passed through the first through hole 254. The introduced air moves upward through the second blocking wall 256, then moves to the rear through the second through hole 258, and then moves to the discharge unit 300 located at the bottom.

In this way, in the process of moving air through the first and second blocking walls 252 and 256, the sterilizing space 240 is contained in the air by the sterilizing space 240 formed between the first and second blocking walls 252 and 256. It stably sterilizes bacteria and viruses.

At this time, a moving path 270 connecting the sterilization and purification unit 200 and the discharge unit 300 is formed at the rear of the second blocking wall 256, so that the air sterilized and purified by the sterilization and purification unit 200 It moves to the discharge unit 300.

And, as another embodiment of the present invention, as shown in FIG. 9, the moving path 270 and the lower part of the second blocking wall 256 dividing the sterilization space 240 with the moving path 270 A circulation passage 262 may be further formed to communicate with the sterilization space 240 .

Here, a circulation fan 260 may be installed in the circulation passage 262 to move the air moving along the passage 270 to the sterilization space 240. Air in the passage 270 and the sterilization space 240 can continuously circulate with each other.

On the other hand, the control unit 400 may further include a sensor module 420. The sensor module 420 can measure the content of carbon dioxide, fine dust, and formaldehyde contained in the air. of temperature and humidity can be measured.

Here, the control device 410 of the controller 400 operates the circulation fan 260 when the content of carbon dioxide, fine dust, and formaldehyde measured by the sensor module 420 is higher than the set value to move the path ( 270) and the air in the sterilization space 240 are continuously circulated for a set time.

At this time, the control device 410 prevents the discharge unit 300 from operating so that the air circulating between the moving path 270 and the sterilization space 240 is not discharged to the outside, thereby maintaining the sterilization space for a set time. Through the UVC light of (240), bacteria and viruses contained in the air are more completely sterilized.

In addition, as described above, although the discharge unit 300 may not be operated, the speed of discharge through the discharge unit 300 is reduced and sterilization is performed in the moving path 270 through the circulation fan 260. By increasing the amount of air moving into the space 240, harmful substances contained in the air may be sterilized more completely.

In addition, the circulation fan 260 can be set to operate or stop at all times. As described above, the discharge amount of the discharge unit 300 and the amount of air to be circulated through the circulation fan 260 are determined according to the air quality. It is controlled to circulate an appropriate amount of air so that it can be sterilized in an optimal state.

In addition, a first air pattern panel 220 may be further installed at the rear of the filter unit 210, that is, at the rear of the second filter 214, and the first air pattern panel 220 penetrates the front and rear. Grid-shaped holes (not shown) may be formed as much as possible, and the shape is not limited thereto and may be formed in various types of hole shapes including circular holes and square holes, protruding circular ball shapes, square shapes, etc. can be formed as

Here, the size of the hole forming the first air pattern panel 220 may be formed to decrease from top to bottom. Since the size of the hole located at the bottom of the first air pattern panel 220 decreases, the lower The air entering the top is more than the air entering the bottom.

At this time, since the first through hole 254 is formed in the lower part of the purification space 230 formed at the rear of the filter part 210, the movement of air to the lower part of the filter part 210 increases, but the 1 The amount of air introduced into the lower part by the air pattern panel 220 is reduced and the amount of air introduced into the upper part is increased so that the amount of air introduced into each part of the filter unit 210 per unit time is uniformly formed as a whole. do.

Therefore, the first and second filters 212 and 214 constituting the filter unit 210 uniformly filter out foreign substances contained in the air as a whole, thereby increasing the filtering efficiency.

In addition, as shown in FIG. 12, the first and second air pattern panels 220' and 330' are formed in a sealed state without through holes and may be formed to protrude in a circular or polygonal shape at regular intervals.

On the other hand, the discharge part 300 formed in the lower part of the case 100 includes a third filter 320 for filtering foreign substances included in the air that has passed through the sterilization and purification part 200 and the third filter 320 It may be made of a discharge fan 310 installed on the front of the sterilized and purified air for discharging the air to the outside.

Thus, by filtering the air discharged to the outside once more through the third filter 320, the air can be more completely purified.

At this time, a second air pattern panel 330 may be further provided at the rear of the third filter 320, and ventilation holes 332 are formed at regular intervals in the second air pattern panel 330. The shape of the ventilation hole 332 may be formed in various shapes such as a lattice-shaped hole, a circular hole, a protruding circular ball shape, and a rectangular shape, and the ventilation hole 332 has a diameter increasing from top to bottom. is formed

Therefore, the air moved from the sterilization and purification unit 200 is uniformly filtered through the entire portion of the third filter 320 .

That is, since the moving path 270 is formed at the rear upper end of the discharge part 300, more air moves through the upper part of the third filter 320, but by the second air pattern panel 330 The amount of air moving to the upper part of the third filter 320 is reduced, and the amount of air moving through the ventilation hole 332 increases as it goes to the lower part.

So, like the filter unit 210 described above, the amount of air moving per unit time is evened out in the entire portion of the third filter 320 to increase the filtering efficiency of the third filter 320 .

In addition, an electronic display board 120 made of LEDs may be further provided on one side of the case 100, and carbon dioxide, fine dust, and form contained in the air measured by the sensor module 420 may be further provided on the electronic display board 120.
