The present invention relates to an electromagnetic wave sterilizer for a refrigerator that can sterilize circulating air through microwaves by installing a magnetron that generates microwaves in the circulating air.
일반적으로 냉장고는 각종 음식물을 냉동, 냉장 상태로 저장하여 장시간 신선도를 유지시키는 데 사용되는 것으로, 그러한 냉장고는 냉동 사이클의 증발기를 음식물 저장공간에 설치하여 직접 열교환을 이루도록 하는 직접 냉각방식과, 증발기를 식품 저장공간으로부터 격리된 통로상에 설치하고 증발기를 통해 열교환된 냉기를 순환팬의 송풍력을 통해 강제로 순환시켜 저장된 음식물을 냉각시키는 간접 냉각방식이 사용되고 있다.In general, refrigerators are used to store various foods in a frozen and refrigerated state to maintain freshness for a long time. Such refrigerators include a direct cooling method for direct heat exchange by installing an evaporator in a refrigeration cycle in a food storage space, and an evaporator. Indirect cooling is used to cool down the stored food by forcibly circulating the cold air exchanged through the evaporator through the blowing force of the circulation fan.
도 1에 도시되는 바와 같이, 간접 냉각식 냉장고(101)는 냉동실(120)과 냉장실(125)을 구분하는 tkwjf판(124)을 사이에 두고 냉동실(120)로부터 냉기가 유입되는 냉동실 흡기덕트(123) 및 냉장실(125)로부터 냉기가 유입되는 냉장실 흡기덕트(127)가 각각 형성되어 있고, 그 냉동실 흡기덕트(123)와 냉장실 흡기덕트(127)가 접속되는 지점에 냉동 사이클의 증발기(130)가 설치되어 있으며, 그 증발기(130)의 하류에 증발기(130)를 통과한 냉기가 냉동실(120)로 토출되도록 하는 냉동실 토출덕트(128) 및 냉장실(125)로 토출되도록 하는 냉장실 토출덕트(129)가 각각 설치되어 있다.As shown in FIG. 1, the indirect cooling refrigerator 101 includes a freezer compartment intake duct through which a cold air flows from the freezer compartment 120 with a tkwjf plate 124 separating the freezer compartment 120 and the refrigerating compartment 125 between them. 123 and the refrigerator compartment intake duct 127 into which cold air flows from the refrigerator compartment 125 are formed, respectively, and the evaporator 130 of the refrigeration cycle is connected to the point where the freezer compartment intake duct 123 and the refrigerator compartment intake duct 127 are connected. Is installed, and the refrigerator compartment discharge duct 129 for discharging the cold air passing through the evaporator 130 to the freezer compartment 120 and the refrigerator compartment 125 to be discharged to the freezer compartment 120 downstream of the evaporator 130. ) Are installed respectively.
또한, 증발기(130)의 하류에는 냉동실 흡기덕트(123) 및 냉장실 흡기덕트(127)를 통해 고내의 냉기를 흡입하고 그 증발기(130)를 통과한 냉기를 냉동실 토출덕트(128) 및 냉장실 토출덕트(129)를 통해 다시 고내로 토출시키는 각각의 순환팬(121)이 설치되어 있다.Further, downstream of the evaporator 130, the cold air in the inside of the refrigerator is sucked through the freezer compartment intake duct 123 and the refrigerator compartment intake duct 127, and the cold air having passed through the evaporator 130 is stored in the freezer compartment discharge duct 128 and the refrigerator compartment discharge duct. Each circulation fan 121 for discharging back into the chamber through 129 is provided.
따라서, 냉동 사이클의 증발기(130)는 냉매가 급격하게 기화됨에 따라 주위의 열을 흡수하게 되고, 이때 순환팬(121)은 냉동실 흡기덕트(123) 및 냉장실 흡기덕트(127)를 통해 냉장실(125) 및 냉동실(120)내의 냉기를 흡입하고 증발기(130)를 통해 열교환시키면서 냉동실 토출덕트(128) 및 냉장실 토출덕트(129)를 통해 다시 냉동실(120) 및 냉장실(125)내로 토출시킴으로써, 고내의 음식물을 냉동, 냉장 저장할 수 있도록 한다.Therefore, the evaporator 130 of the refrigerating cycle absorbs the surrounding heat as the refrigerant is rapidly vaporized, and the circulation fan 121 is the refrigerating chamber 125 through the freezer compartment intake duct 123 and the refrigerating compartment intake duct 127. ) And the cold air in the freezer compartment 120 are discharged back into the freezer compartment 120 and the refrigerating compartment 125 through the freezer compartment discharge duct 128 and the refrigerator compartment discharge duct 129 while heat exchanged through the evaporator 130. Allow food to be frozen and refrigerated.
그런데, 상술한 바와 같은 간접 냉각식 냉장고(101)에서, 특히 냉장실(125)은 밀폐된 상태로 냉장식품을 저장하게 되므로 오래 사용할 경우 유해균이 서식하게 되어 냉장식품이 비위생적이 된다.By the way, in the indirect cooling refrigerator 101 as described above, in particular, the refrigerator compartment 125 stores the refrigerated food in a sealed state, so that when used for a long time, harmful bacteria are inhabited and the refrigerated food becomes unsanitary.
이에 따라, 최근 냉장고내에는 유해균을 살균하기 위한 살균장치가 구비되고 있은 바, 이러한 냉장고의 살균장치로서는 국내 공개특허 제96-41965호에 기재된 냉장고의 살균액 분무방식 살균장치 및 국내 공개실용 제97-44676호에 기재된 냉장고의 자외선 살균장치가 알려져 있다.Accordingly, recently, a sterilizer for sterilizing harmful bacteria is provided in a refrigerator.

To be sterilized while colliding with the burst, which has the problem of having to replenish the disinfectant consumed in the sterilization container, etc. from time to time.
한편, 상술한 냉장고의 자외선 살균장치는 냉장실에 설치된 자외선살균실에 자외선램프를 구비함으로써 살균대상물건을 자외선살균실에 넣어 자외선 살균할 수 있게 되는 것이나, 이는 한정된 공간 즉 자외선램프가 설치된 자외선산균실에서만 살균력을 갖게 되므로 냉장실 전반에 걸쳐 살균할 수는 없게 되는 문제점이 있다.On the other hand, the above-described ultraviolet sterilizer of the refrigerator is provided with an ultraviolet lamp in the ultraviolet sterilization chamber installed in the refrigerating room to be able to sterilize the ultraviolet rays put the object to be sterilized in the ultraviolet sterilization chamber, which is a UV sterilization chamber equipped with a limited space, the ultraviolet lamp Only because it has a sterilizing power there is a problem that can not be sterilized throughout the refrigerator compartment.
따라서, 본 발명은 상술한 바와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 냉장실로부터 순환공기가 흡입되는 냉장실 흡기덕트내에 마이크로웨이브를 발생시켜 순환공기를 살균함으로써 고내 곳곳을 확실하게 살균할 수 있도록 함은 물론 소모부품 없이 반영구적으로 사용할 수 있도록 하는 냉장고의 살균장치를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above-mentioned problems, so that the microwaves are generated in the refrigerating chamber intake duct in which the circulating air is sucked from the refrigerating chamber to sterilize the circulating air so as to reliably sterilize various places in the refrigerator. The purpose of the present invention is to provide a sterilizer of a refrigerator that can be used semi-permanently without consumable parts.

이하, 본 발명의 실시예를 첨부도면에 의거하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
도 2는 본 발명의 실시예에 따른 전자파 살균장치(50)가 적용되는 간접 냉각식 냉장고(1)를 보인 것으로서, 이 냉장고(1)는 착상판(24)을 사이에 두고 냉동실(20)로부터 냉기가 유입되는 냉동실 흡기덕트(23) 및 냉장실(25)로부터 냉기가 유입되는 냉장실 흡기덕트(27)가 각각 형성되고, 그 냉동실 흡기덕트(23)와 냉장실 흡기덕트(27)가 접속되는 지점에 냉동 사이클의 증발기(30)가 설치되며, 그 증발기(30)의 하류에 증발기(30)를 통과한 냉기가 냉동실(20)로 토출되도록 하는 냉동실 토출덕트(28) 및 냉장실(25)로 토출되도록 하는 냉장실 토출덕트(29)가 각각 설치된다.FIG. 2 shows an indirect cooling refrigerator 1 to which an electromagnetic wave sterilizer 50 according to an embodiment of the present invention is applied. The refrigerator 1 is provided from a freezing chamber 20 with an implantation plate 24 interposed therebetween. The refrigerator compartment intake duct 23 into which cold air flows is formed, respectively, from the freezer compartment intake duct 23 into which cold air flows, and the freezer compartment intake duct 23 and the refrigerator compartment intake duct 27 connected to each other. An evaporator 30 of the refrigerating cycle is installed and discharged to the freezer compartment discharge duct 28 and the refrigerating chamber 25 to allow the cold air passing through the evaporator 30 to be discharged to the freezer compartment 20 downstream of the evaporator 30. Refrigerating chamber discharge ducts 29 are respectively provided.
또한, 증발기(30)의 하류에는 냉동실 흡기덕트(23) 및 냉장실 흡기덕트(27)를 통해 고내의 냉기를 흡입하고 그 증발기(30)를 통과한 냉기를 냉동실 토출덕트(28) 및 냉장실 토출덕트(29)를 통해 다시 고내로 토출시키는 각각의 순환팬(21)이 설치된다.Further, downstream of the evaporator 30, cold air in the inside of the refrigerator is sucked through the freezer compartment intake duct 23 and the refrigerator compartment intake duct 27, and the cold air passing through the evaporator 30 is freezer compartment discharge duct 28 and the refrigerator compartment discharge duct. Each circulation fan 21 for discharging back into the chamber through 29 is provided.
그리고, 냉장실 흡기덕트(27)내에는 마이크로웨이브를 통해 냉장실 순환공기를 살균 처리하는 전자파 살균장치(50)가 장착된다.In the refrigerating chamber intake duct 27, an electromagnetic sterilization apparatus 50 for sterilizing the refrigerating chamber circulating air through a microwave is mounted.
여기서, 본 발명의 실시예에 따른 냉장고의 전자파 살균장치(50)는 도 3에 도시되는 바와 같이, 냉장실 흡기덕트(27)내에 살균관(51)이 장착되고, 그 살균관(51)의 일측에는 마이크로웨이브를 발생시키는 마그네트론(53)이 설치된다.Here, as shown in Figure 3, the microwave sterilization apparatus 50 of the refrigerator according to the embodiment of the present invention, the sterilization tube 51 is mounted in the refrigerating chamber intake duct 27, one side of the sterilization tube 51 The magnetron 53 for generating a microwave is installed.
살균관(51)은 원통형으로 이루어져 냉장실 흡기덕트(27)를 통과하는 모든 순환공기가 원활하게 내부를 통과할 수 있도록 원주상에 미세한 관통홀(52)이 다수개 배열 형성된다. 이 관통홀(52)은 마이크로웨이브의 누설을 막아 안정된 살균이 이루어지도록 약 1~6mm의 직경으로, 바람직하게는 약 2mm의 직경으로 관통 형성된다.The sterilization tube 51 has a cylindrical shape, and a plurality of fine through-holes 52 are formed on the circumference so that all the circulation air passing through the refrigerating chamber intake duct 27 can pass smoothly therein. The through holes 52 are formed to have a diameter of about 1 to 6 mm, preferably about 2 mm, to prevent the leakage of microwaves to achieve stable sterilization.
그리고, 마그네트론(53)은 자계를 가하여 전자류를 제어하는 특수한 진공관으로서 마이크로웨이브를 강력하게 발생시키게 되는 바, 이렇게 발생되는 마이크로웨이브는 살균관(51)의 관통홀(52)을 통과하는 냉장실 순환공기중으로 방사된다. 마그네트론(53)의 동작은 냉장고를 전반적으로 제어하는 마이콤에 의해 제어된다.In addition, the magnetron 53 is a special vacuum tube to control the electromagnetic flow by applying a magnetic field to generate a microwave strongly, the microwave generated in this way is a refrigerating chamber circulation passing through the through hole 52 of the sterilization tube 51 Radiated into the air. The operation of the magnetron 53 is controlled by the microcomputer that controls the refrigerator as a whole.
이와 같이 구성되는 본 발명의 실시예에 따른 전자파 살균장치(50)의 작용을 설명하면 다음과 같다.Referring to the operation of the electromagnetic sterilization device 50 according to an embodiment of the present invention configured as described above are as follows.
우선, 전자파 살균장치(50)의 동작에 앞서, 냉동 사이클의 증발기(30)는 냉매가 급격하게 기화됨에 따라 주위의 열을 흡수하게 된다. 이때 순환팬(21)은 냉동실 흡기덕트(23) 및 냉장실 흡기덕트(27)를 통해 냉장실(25) 및 냉동실(20)내의 냉기를 흡입하고 증발기(30)를 통해 열교환시키면서 냉동실 토출덕트(28) 및 냉장실 토출덕트(29)를 통해 다시 냉동실(20) 및 냉장실(25)내로 토출시킴으로써, 고내의 음식물을 냉동, 냉장 저장할 수 있도록 한다. 이때, 냉장실(25)로부터 흡입되는 냉장실 흡기덕트(27)의 순환공기는 다수의 미세 관통홀(52)을 통해 전자파 살균장치(50)의 살균관(51)을 통과하게 된다.First, prior to the operation of the electromagnetic sterilizer 50, the evaporator 30 of the refrigerating cycle absorbs the heat of the surroundings as the refrigerant rapidly evaporates. At this time, the circulation fan 21 sucks cold air in the refrigerating compartment 25 and the freezing compartment 20 through the freezer compartment intake duct 23 and the refrigerating compartment intake duct 27, and exchanges heat through the evaporator 30. And by discharging back into the freezer compartment 20 and the refrigerating compartment 25 through the refrigerator compartment discharge duct 29, the food in the refrigerator can be frozen, refrigerated and stored. At this time, the circulation air of the refrigerating chamber intake duct 27 suctioned from the refrigerating chamber 25 passes through the sterilization tube 51 of the electromagnetic sterilization apparatus 50 through the plurality of fine through holes 52.
이러한 과정에서, 냉장실 흡기덕트(27)내에 장치된 전자파 살균장치(50)의 마그네트론(53)은 순환팬(21)에 의한 냉기 순환 사이클에 따라 동작되는 바, 일단 마이콤에 의해 동작되면 살균관(51)에 마이크로웨이브를 발생시키게 되고, 이렇게 발생된 마이크로웨이브는 살균관(51)의 관통홀(52)을 통과하는 냉장실 순환공기에 가해져 공기중에 서식/포함된 유해균을 살균 처리하게 된다.In this process, the magnetron 53 of the electromagnetic sterilization device 50 installed in the refrigerating chamber intake duct 27 is operated according to the cold air circulation cycle by the circulation fan 21. Once operated by the microcomputer, the sterilization tube ( The microwave is generated in 51), and the generated microwave is applied to refrigerating chamber circulating air passing through the through hole 52 of the sterilization tube 51 to sterilize harmful bacteria inhabited / embedded in the air.
이때, 순환팬(21)에 의해 고내 순환되는 공기는 약 5 ~ 10초 정도의 짧은 시간내에 순환되므로, 마이크로웨이브가 가해진다 하여도 거의 가열되지 않는다. 또한, 냉장실(25)로부터 흡입되는 순환공기중에는 많은 수분을 함유하고 있으므로, 마이크로웨이브와 쉽게 반응하여 살균작용을 촉진시킬 수 있게 된다.At this time, the air circulated in the air by the circulation fan 21 is circulated within a short time of about 5 to 10 seconds, so that even if microwave is applied, it is hardly heated. In addition, since the circulating air sucked from the refrigerating chamber 25 contains a lot of water, it is possible to easily react with the microwave to promote sterilization.
따라서, 마이크로웨이브에 의해 살균 처리된 순환공기는 냉장실 토출덕트 (29)및 냉동실 토출덕트(28)를 통해 고내 곳곳을 순환하게 되므로 균일하고도 확실한 고내 살균을 이룰 수 있게 된다.Therefore, the circulated air sterilized by the microwaves circulates in the refrigerator through the refrigerating chamber discharge duct 29 and the freezing chamber discharge duct 28, thereby achieving uniform and reliable internal sterilization.
이상에서 살펴본 바와 같이, 본 발명은 냉장실로부터 순환공기가 흡입되는 냉장실 흡기덕트내에 마이크로웨이브를 발생시켜 순환공기를 살균함으로써 기존 자외선 램프를 이용하는 살균장치에 비해 고내 곳곳을 확실하게 살균 처리할 수 있게 되고, 또한 살균 처리시 소모부품 없이 반영구적으로 사용할 수 있게 되므로 사용이 편리함은 물론 소모부품 교환에 따른 소요비용을 없앨 수 있는 효과가 있다.As described above, the present invention, by generating microwaves in the refrigerating chamber intake duct in which the circulating air is sucked from the refrigerating chamber to sterilize the circulating air, it is possible to reliably sterilize various parts of the inside of the refrigerator compared to the sterilization apparatus using the conventional ultraviolet lamp. In addition, since it can be used semi-permanently without consumable parts during sterilization treatment, it is convenient to use and can eliminate the cost of replacing consumable parts.
본 발명은 특정의 실시예와 관련하여 도시 및 설명하였지만, 첨부 특허청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 당업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described with respect to particular embodiments, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the appended claims. Anyone can easily know.
