본 고안은 자외선의 강력한 살균력을 이용하여 공기중의 세균포자나 곰팡이의 부유균등을 살균시켜줌과 동시에 탈취용 광촉매를 사용하여 냄새를 분해, 제거시켜 주도록 한 냉장고의 살균 및 탈취장치에 대한 것이다.The present invention relates to a sterilizer and a deodorizer for a refrigerator which sterilizes bacterial spores and fungi floating fungi in the air by using a strong sterilizing power of ultraviolet rays and decomposes and removes odors using a photocatalyst for deodorization.
종래에는 냉장고내에 오존발생기를 설치하여 오존을 이용 악취성분의 냄새를 분해하는 산화환원방식을 이용한 탈취장치가 있었는데, 이러한 장치는 고전압발생기 및 방전전극에 의해 무성방전으로 공기중의 산소를 전리시켜 오존을 발생케 함으로써, 악취 냄새와의 반응에 의해서 냄새를 분해하고, 반응하지 않는 오존은 다시 오존분해촉매를 거치면서 산소로 환원시켜 줌으로써 고내 공기중의 냄새를 탈취시켜 주도록 한 것이다.Conventionally, there has been a deodorization device using a redox method in which a ozone generator is installed in a refrigerator to decompose odors of odorous components using ozone. This device ionizes oxygen in the air by silent discharge by a high voltage generator and a discharge electrode. By decomposing odor, the odor is decomposed by the reaction with the odor odor, and the unreacted ozone is reduced to oxygen while passing through the ozone decomposition catalyst to deodorize the odor in the air.
그러나, 이 장치는 산화환원방식에 의해 탈취는 가능하지만 공기중의 세균포자나 곰팡이 부유균등의 살균작용은 아주 미약하여 세균번식에 의해 음식물의 변질이나 부패를 효과적으로 방지하여 주지 못하는 결점이 있으며, 또 발생된 오존이 장치의 구조적 결함등에 의해 분해되지 않은 오존은 고내에 잔존하여 오존특유의 비릿한 냄새등을 유발하게 되는 결점도 있었다.However, this device is capable of deodorization by redox method, but it is very weak in sterilizing action such as bacterial spores and fungi floating bacteria in air, which does not effectively prevent food deterioration or decay by bacterial propagation. Ozone, which has not been decomposed by the structural defects of the generated ozone, remains in the chamber and causes an ozone-specific odor.
또한, 장기간 사용시 방전전극 표면에 미립의 먼지가 부착되거나, 도어개폐시 습기가 부착되면 오존발생량이 줄어들게 되고 이에 따라 탈취효과가 저하되는 등의 문제점들도 있었다.In addition, when long-term use, particulate dust adheres to the surface of the discharge electrode, or moisture is attached to the door opening and closing, there is a problem that the amount of ozone is reduced and thus the deodorizing effect is reduced.
본 고안은 이러한 점들을 해결하기 위해 고안한 것으로서, 고내의 후면벽 적정위치에 자외등과 광촉매를 내부에 설치한 살균 및 탈취장치를 설치하여 고내의 공기를 순환팬으로 강제흡입시켜 탈취장치내의 자외등과 광촉매를 차례로 거치도록 하면서 자외등에서 발생되는 자외선의 강력한 살균력에 의해서는 공기중의 균들이 살균되게 하고, 또 광촉매를 거치면서는 자외등의 광에너지에 의해 여기(勵起)되어 광촉매의 표면에 발생되는 수산기(OH Redical)의 산화작용으로 냄새성분이 산화분해되어 제거되도록 함으로써 효과적으로 살균 및 냄새제거가 되도록 한 것이다.The present invention has been devised to solve these problems. The sterilization and deodorization device with ultraviolet light and photocatalyst installed inside the rear wall of the interior is installed in the deodorization system by forcibly sucking the air in the interior with a circulation fan. While passing through the light and photocatalyst in turn, the germs in the air are sterilized by the strong germicidal power of ultraviolet light generated from the ultraviolet light.The photocatalyst is excited by light energy such as ultraviolet light and is applied to the surface of the photocatalyst. By oxidizing the hydroxyl group (OH Redical) generated by the odor component is oxidized decomposition is removed to be effectively sterilization and odor removal.

흡입구(21)와 토출구(22)는 냉장실(11)내에 위치하게 하고, 자외선 조사구(23)는 냉장실(11)의 상부에 별도로 부설하는 살균실(12)의 후면 일측에 뚫어 설치한 자외선유통구(12a)와 일치하도록 한다.The suction port 21 and the discharge port 22 are positioned in the refrigerating chamber 11, and the ultraviolet irradiation hole 23 is drilled on one side of the rear side of the sterilization chamber 12 separately installed at the upper part of the refrigerating chamber 11, and the UV distribution is installed. To match the sphere (12a).
제2도에는 본 고안 장치가 구체적으로 도시되어 있다.2 shows the device of the present invention in detail.
케이스(2)내에는 흡입구(21)로부터 토출구(22)를 연결하는 공기순환통로(24)가 형성되어 있고 이 통로의 흡입구(21)측에는 자외등(3)을, 중간위치에는 광촉매(4)를 각각 고정 착설한다.An air circulation passage 24 is formed in the case 2 to connect the outlet 22 from the inlet 21. The ultraviolet light 3 is provided on the inlet 21 side of the passage, and the photocatalyst 4 is located in the intermediate position. Each stationary installation.
토출구(22)측에는 순환팬(5)을 팬모우터(51)에 의해 회전되게 설치하여 이 순환팬을 동작시키면 냉장실(11)내의 공기가 흡입구(21)를 통해 케이스(2)내로 흡입되어 공기순환통로(24)를 따라 이동하면서 자외등(3)과 광촉매(4)를 차례로 거친 다음 토출구(22)를 통해 다시 냉장실(1)내로 토출하도록 하였다.When the circulation fan 5 is rotated by the fan motor 51 at the discharge port 22 side and the circulation fan is operated, the air in the refrigerating chamber 11 is sucked into the case 2 through the suction port 21 and the air is While moving along the circulation passage 24, the ultraviolet light 3 and the photocatalyst 4 were sequentially passed through the discharge passage 22 and then discharged back into the refrigerating chamber 1 through the discharge port 22.
따라서, 자외등(3)에서 발생되는 자외선에 의해서는 공기중의 균들이 살균되고, 또 광촉매(4)를 거치면서는 냄새가 제거되도록 한다.Therefore, by the ultraviolet rays generated in the ultraviolet light (3), bacteria in the air are sterilized, and the odor is removed while passing through the photocatalyst (4).
광촉매(4)는, 활성탄(活性炭)으로 하니컴형상이되게 성형한 흡착제를 베이스(Base)로 하여 그 표면에 금속산화물로 이루어진 반도체 미립자, 예를 들면 이산화티탄(Tio2)을 담지 소성하여 코팅시켜 구성한다.The photocatalyst 4 is formed by adsorbing an activated adsorbent formed into a honeycomb shape with activated carbon as a base, and baking and coating a semiconductor fine particle, for example, titanium dioxide (Tio 2 ), on the surface thereof. Configure.
반도체 미립자는, 가전자대(Valence band)와 배드 갭(Band gap) 및 전도대(Conduction band)로 구성된다.The semiconductor fine particles are composed of a valence band, a bad gap, and a conduction band.
또한, 살균실(12)의 전면에 축착하는 도어(12b)의 상단부 일측에는 마그네트(12c)를 착설하고, 상면판(13)에는 감지스위치(5)를 마그네트(12c)에 의해 동작되게 설치하여 도어(12b)를 닫으면 감지스위치(5)가 "온"되어 자외등(3)이 점등되며, 도어(12b)를 열면 감지스위치(12d)가 "오프"되어 소등되게 함으로서 자외선의 누설이 방지되게 하였다.In addition, a magnet 12c is installed on one side of an upper end portion of the door 12b that is condensed on the front surface of the sterilization chamber 12, and a sensing switch 5 is installed on the upper plate 13 so as to be operated by the magnet 12c. When the door 12b is closed, the detection switch 5 is turned on to turn on the ultraviolet light 3, and when the door 12b is opened, the detection switch 12d is turned off to be turned off to prevent the leakage of ultraviolet rays. It was.
제4-5도는 종래의 오존발생기에 의한 냄새제거 장치를 보인 것이다.4-5 shows an odor removing apparatus using a conventional ozone generator.
이 종래의 장치는, 케이스(20)내의 공기순환통로(20')에 고압발생기(30)와 오존분해촉매(40)를 설치하여 순환팬(50)을 동작시켜 고내의 공기를 강제 흡입하여 순환통로(20')를 통과시키면서 고압발생기(30)의 방전전극(30')으로부터 방전되는 전극이 공기층의 산소를 전리시켜 발생하는 오존에 의해 냄새가 제거되도록 하고, 전류 오존은 분해촉매에 의해 산소로 환원되도록 구성한 것인데, 이 장치의 결합은 탈취는 가능하지만 세균의 살균작용은 마주 미약하며, 도 구조적인 결함, 예를 들어 순환팬(50)이 정지되는 경우 오존이 흘러나와 오히려 고내에서 오존에 의한 냄새가 발생되는 등 탈취와 살균작용이 불량한 결점이 있다.In this conventional apparatus, the high pressure generator 30 and the ozone decomposition catalyst 40 are installed in the air circulation passage 20 'in the case 20, and the circulation fan 50 is operated to forcibly suck air in the air and circulate it. The electrode discharged from the discharge electrode 30 'of the high-pressure generator 30 while passing through the passage 20' causes the odor to be removed by ozone generated by ionizing oxygen in the air layer, and the current ozone is oxygen by a decomposition catalyst. It is configured to be reduced to, but the combination of the device is possible to deodorize, but the bactericidal action is very weak, and structural defects, for example, when the circulation fan 50 is stopped ozone flows to the ozone in the interior rather than Deodorization and sterilization effect is poor, such as odor is generated.
그러나, 본 고안 장치는, 순환팬(5)에 의해 공기가 흡입구(21)를 통해 순환통로(24)내로 흡입되면 제3도에서 보는 바와 같이 자외등(3)을 통과할 때 강력한 살균작용을 하는 자외선에 의해 공기중의 균들이 살균된다.However, the device of the present invention, when the air is sucked into the circulation passage 24 through the suction port 21 by the circulation fan 5, as shown in FIG. 3 shows a strong sterilization action when passing through the ultraviolet light (3) Ultraviolet germs are sterilized in the air.
이후 공기는 광촉매(4)를 통과하는 과정에서 이 광촉매에 흡착됨과 동시에 산화분해 되어 제거된다.The air is then adsorbed to the photocatalyst in the course of passing through the photocatalyst 4 and is oxidized and removed.
이러한 작용은, 이 광촉매에 자외등(3)의 광에너지가 조사되면 그 표면에 코팅되어 있는 반도체 미립자의 가전자대에 있는 전자가 광에너지를 얻어 밴드갭을 지나 전도대로 튀어 나오게 되고, 전자가 튀어나간 정공(正孔)은 가전자대에 있게 되는 상태, 즉 광촉매(4)의 여기 상태가 되는데, 이렇게 되면 광촉매의 표면으로부터 강력한 산화력을 가즌 수산기(OH-)가 발생되고, 이 수산기에 의해 냄새성분이 산화 분해되어 제거되는 것이며, 이렇게 되어 냄새가 제거된 공기는, 토출구(22)를 거쳐 다시 냉장실(11)내로 토출되는 것으로 이러한 순환과정이 계속됨으로써 냉장실(11)내의 공기는 살균 및 냄새제거가 되는 것이다.This effect is that when the light energy of the ultraviolet light 3 is irradiated to the photocatalyst, electrons in the valence band of the semiconductor fine particles coated on the surface of the photocatalyst obtain light energy and protrude through the conduction band through the band gap, and the electrons pop out. The outgoing hole is in the valence band, that is, the excited state of the photocatalyst 4, which generates a strong oxidizing force (OH-) from the surface of the photocatalyst, and the odor component is caused by the hydroxyl group. The oxidative decomposition is removed, and thus the air from which the odor is removed is discharged back into the refrigerating chamber 11 through the discharge port 22. As a result of this circulation process, the air in the refrigerating chamber 11 is sterilized and deodorized. Will be.
또한, 자외등(3)에서 발생되는 자외선의 일부는 케이스(2) 전면상부의 자외선조사구(23)와 살균실(12) 후면 일측에 뚫어 설치한 자외선유통구(12a)를 통과하여 살균실(12)내로 조사되어 이 살균실내의 균들을 살균시켜 주도록 하였기 때문에 냉장고(1)내에 별도의 살균공간을 확보하게 되는 것이다.In addition, a part of the ultraviolet rays generated from the ultraviolet light 3 passes through the ultraviolet irradiation port 23 on the front of the case 2 and the ultraviolet distribution port 12a installed at one side of the rear side of the sterilization chamber 12 to sterilize the chamber. Since it was irradiated into (12) to sterilize the germs in the sterilization chamber, a separate sterilization space is secured in the refrigerator 1.
이와 같이 본 고안은, 공기중의 균들의 살균과 냄새의 제거로 냉장고를 위생적으로 안심하고 사용할 수 있게 하여 주는 매우 유용한 고안이다.In this way, the present invention is a very useful design that makes it possible to use the refrigerator hygienically and safely by sterilizing and removing odors of bacteria in the air.
