본 발명은 냉장고에 보관되는 식품의 신선도 유지를 위한 기술로서, 특히 냉기가 순환되어 귀환되는 냉기귀환로에 선도유지장치를 설치하고, 흡착 및 탈착이 효과적으로 이루어지도록 한 냉장고의 선도유지장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for maintaining freshness of food stored in a refrigerator, and more particularly, to installing a freshness retaining device in a cold air return path in which cold air is circulated and returned, and to effectively maintain adsorption and desorption. .
일반적인 냉장고는 제1도에 도시한 바와 같이, 본체(1)가 냉동실(2)과 냉장실(3)로 구분되고, 냉동실(2)의 후면벽체에는 순환팬(4)과 증발기(5)가 설치되어 있으며, 냉장실(3)의 하부에는 야채박스(6)가 구비되어 있는 구성이다.In a typical refrigerator, as shown in FIG. 1, the main body 1 is divided into a freezing compartment 2 and a refrigerating compartment 3, and a circulation fan 4 and an evaporator 5 are installed on the rear wall of the freezing compartment 2. The lower part of the refrigerating compartment (3) is provided with a vegetable box (6).
이러한 구성을 갖는 냉장고에서 열교환기를 통과한 냉기는 순환팬(4)에 의해 냉동실(2) 내부를 순환한 뒤, 냉동실(2)의 하면에 형성되어 있는 냉동실 냉기 유입구(2a)를 통해 냉기순환로(1a)로 순환되어 이 냉기가 냉장실(3)의 후면벽체의 냉기순환로(1b)를 따라 이동되어 냉장실(3)의 후면벽체에 형성된 냉기유출구(1c)를 통해 냉장실(3)의 내부로 유입되며, 냉장실을 순환한 냉기는 다시 냉장실 냉기 유입구(3a)를 통해 증발기로 순환된다.The cold air having passed through the heat exchanger in the refrigerator having such a configuration circulates inside the freezing compartment 2 by the circulation fan 4, and then passes through the freezing compartment cold air inlet 2a formed at the lower surface of the freezing compartment 2. Circulated to 1a), the cold air is moved along the cold air circulation path 1b of the rear wall of the refrigerating chamber 3 and introduced into the refrigerating chamber 3 through the cold air outlet 1c formed in the rear wall of the refrigerating chamber 3. The cold air circulated in the refrigerating compartment is circulated to the evaporator through the refrigerating compartment cold air inlet 3a.
이와 같이 냉기가 순환되는 종래 냉장고에서는 냉장실(3)의 상측 후면부에 제2도에 도시한 바와 같은, 선도유지장치(7)가 설치되어 있어 냉장실의 냄새성분을 제거함으로써 보관되는 냉장식품의 신선도를 유지하도록 하고 있다.In the conventional refrigerator in which cold air circulates as described above, the freshness holding device 7 shown in FIG. 2 is installed at the upper rear side of the refrigerating compartment 3 to remove freshness of the refrigerated food stored by removing the odor component of the refrigerating compartment. I'm keeping it.
상기 선도유지장치(7)는 도시한 바에서 보는 것처럼, 케이스(11)의 양측으로 공기가 흡, 토출되는 공기흡입구(12)와 공기토출구(13)가 형성되어 있고, 케이스(11)의 내측으로 공기를 유입 및 토출시키는 순환팬(14)과, 유입된 공기를 탈취시키는 활성탄 재질의 허니컴(Honeycomp)형(300~400cell/im2)의 탈취필터(15)와, 상기 탈취필터(15)를 통과한 공기의 에칠렌(C2H2)성분을 제거시키는 에칠렌필터(16)가 설치되어 있다.As shown in the drawing, the lead holding device 7 is provided with air inlets 12 and air outlets 13 through which air is sucked and discharged on both sides of the case 11, and the inside of the case 11. A circulation fan 14 for introducing and discharging air into the air, a honeycomb (300-400 cell / im2) deodorizing filter 15 made of activated carbon, and a deodorizing filter 15 for deodorizing the introduced air. The ethylene filter 16 which removes the ethylene (C2H2) component of the air which passed through is provided.
통상적으로 상기 에칠렌은 일반 과일의 유통과정에서 수확한 미숙성된 과일을 출하전에 속성으로 숙성시키기 위해 사용되는 가스인만큼 이러한 에칠렌이 많이 발생되는 사과와 같은 과일을 다른 과일과 함께 보관하게 되면 다른 과일의 신선도를 유지하는데 어려움이 있게 된다.Typically, the ethylene is a gas used to ripen unmature fruits harvested in the distribution process of ordinary fruits with properties before shipment, so when the fruits such as apples that generate a lot of ethylene are stored together with other fruits, other fruits Difficulties in maintaining freshness.
그런데, 상기한 바와 같은 종래 선도유지장치가 구비되어 있는 냉장고에서는 냉장실(3)의 상부에 선도유지장치(7)가 설치되어 있기 때문에 실제적으로 과일이나 야채는 냉장실(3) 하부에 설치되어 있는 야채박스(7)에 격리되어 보관되어 있음으로 해서 탈취필터에 의한 냉장실 내부의 냄새성분을 제거시키는 효과가 다소 발생하지만 에칠렌성분를 제거시키는 효과는 그다지 크지 못한 형편이다.By the way, in the refrigerator provided with the conventional lead holding device as described above, since the lead holding device 7 is installed in the upper part of the refrigerating chamber 3, the fruits and vegetables are actually vegetables that are installed in the lower part of the refrigerating chamber 3. Since it is stored in the box 7 to remove the odor component inside the refrigerating chamber by the deodorizing filter, the effect of removing the ethylene component is not so great.
또한, 상기 탈취필터 및 에칠렌필터는 주로 활성탄 재질을 소재로 하여 제조되므로 제거하려는 성분의 흡착에 의해서만이 탈취가 이루어지기 때문에 냄새성분의 제거도 완벽하게 이루어지기가 어려우며, 일정기간 냄새가 흡착되면, 냄새성분이 필터에 포화상태가 되어 필터의 수명이 다하게 되어 필터의 재생 또는 교환을 요하게 되는 문제가 있다.In addition, since the deodorizing filter and the ethylene filter are mainly made of activated carbon material, since the deodorization is performed only by adsorption of the component to be removed, it is difficult to completely remove the odor component. There is a problem in that the odor component becomes saturated in the filter and the filter reaches its end of life, requiring regeneration or replacement of the filter.
이와 같은 문제점을 감안하여 안출한 본 발명의 목적은 냉기귀환로에 선도유지장치를 설치하여 고내 공기의 탈취 및 살균을 보다 효과적으로 수행하려는 것이다.The object of the present invention devised in view of such a problem is to install the leading holding device in the cold air return path to more effectively perform the deodorization and sterilization of the air in the air.
본 발명의 다른 목적은 선도유지장치에 고흡작/광촉매기능을 수행하는 물질을 사용하여 흡착, 광촉매산화분해 및 달착의 사이클이 영구적으로 이루어져 선도유지장치의 교환이 필요없어 사용자의 편의를 도모하려는 것이다.Another object of the present invention is to use a material that performs a high adsorption / photocatalytic function in the lead holding device is to permanently cycle the adsorption, photocatalytic oxidation decomposition and desorption, so as to facilitate the user's convenience without the need to replace the lead holding device .
이러한 본 발명의 목적을 달성하기 위하여, 냉동실과 냉장실을 순환한 냉기가 증발기로 귀환되는 냉기의 귀환로에 선도유지장치를 설치한 냉장고가 있어서, 상기 선도유지장치는 냉기가 귀환되는 방향으로 냉기유입그릴이 형성된 판넬과, 상기 판넬을 복개하며 내벽면에는 고흡착/광촉매 박막이 코팅된 램프 커버와, 상기 램프 커버의 일측부에 설치되어 발광되는 자외선 램프로 구성된 것을 특징으로 하는 냉장고의 선도유지장치가 제공된다.In order to achieve the object of the present invention, there is a refrigerator provided with a lead holding device in the return path of the cold air to the cold air circulated in the freezer compartment and the refrigerating chamber, the lead holding device is a cold air inlet in the direction that the cold air is returned A refrigerator-maintaining device of a refrigerator, comprising a panel having a grill, a lamp cover coated with a high adsorption / photocatalyst thin film on an inner wall of the panel, and an ultraviolet lamp installed at one side of the lamp cover to emit light Is provided.
이하, 상기한 바와 같은 본 발명을 첨부도면에 도시한 일실시례에 의거하여 보다 상세하게 설명한다.Hereinafter, the present invention as described above will be described in more detail based on one embodiment shown in the accompanying drawings.
첨부도면 제3도는 본 발명에 의한 선도유지장치가 설치된 냉장고의 종단면도이고, 제4도는 본 발명 선도유지장치의 구성을 보인 사시도로서, 이에 도시한 바와 같이, 본 발명 냉장고는 본체(21)가 냉동실(22)과 냉장실(23)로 구분되고, 냉장실(23)의 후면벽체에는 순환팬(24)과 증발기(25)가 설치되어 있으며, 냉장실(23)의 하부에는 야채박스(26)가 구비되어 있고, 냉동실(22)의 하면에는 냉동실 냉기 유입구(22a)가 형성되어 있으며, 냉동실(22)의 하면벽체와, 냉장실(23)의 후면벽체에는 냉기순환로(21a)(21b)와, 냉장실의 내부로 냉기가 유입되는 냉기유출구(21c)가 형성되어 있고, 냉장실(23)의 전방측 상단부에는 냉장실 냉기 유입구(23a)가 형성되어 있는 구성은 종래와 동일하다.3 is a longitudinal cross-sectional view of a refrigerator provided with a freshness holding device according to the present invention, and FIG. 4 is a perspective view showing the structure of the freshness holding device according to the present invention. It is divided into a freezer compartment 22 and a refrigerating compartment 23. The rear wall of the refrigerating compartment 23 is provided with a circulation fan 24 and an evaporator 25, and a vegetable box 26 is provided below the refrigerating compartment 23. The freezer compartment cold air inlet 22a is formed on the lower surface of the freezer compartment 22, and the cold air circulation passages 21a and 21b are provided on the bottom wall of the freezer compartment 22 and the rear wall of the refrigerator compartment 23. The cold air outlet 21c into which cold air flows in is formed, and the refrigerator compartment cold air inlet 23a is formed in the upper end part of the front side of the refrigerator compartment 23, and is the same as the conventional structure.
상기한 바와 같은 구성에서 본 발명에 의한 냉장고는 냉장실(23)을 순환 냉기가 증발기(25)측으로 귀환하는 냉장실 냉기 유입구(23a)에 선도유지장치(27)를 설치한 것을 특징으로 한다.In the above-described configuration, the refrigerator according to the present invention is characterized in that the lead holding device 27 is installed in the refrigerating chamber cold air inlet 23a through which the circulating cold air returns to the evaporator 25 side.
이러한 선도유지장치(27)는 냉기가 유입되는 방향으로 형성된 냉기유입그릴(31a)이 형성된 냉기유입그릴판넬(31)에 상부를 램프 커버(32)가 복개되어 있고, 이 램프 커버(32)에 일측에 자외선 램프(33)가 설치되어 있으며, 램프(33)는 램프접속부(34)에 의해 램프의 일측부에 설치되어 있다.The lead holding device 27 has a lamp cover 32 covered with an upper portion of a cold air inflow grill panel 31 having a cold air inflow grill 31a formed in a direction in which cold air flows. An ultraviolet lamp 33 is provided at one side, and the lamp 33 is provided at one side of the lamp by the lamp connection part 34.
상기 램프 커버(32)의 내벽면에는 활성탄 및 TiO2광촉매로서 고흡착/광촉매박막이 코팅되어 있는데, 이 코팅막은 일반 야자 활성탄을 파쇄해서 미립자상(10㎛)으로 형성한 분말(35)과, 광촉매 활성을 띠는 산화티타늄을 미립자화한 분말(36)을 물, 바인더(Binder;TEG등)등과 잘 혼합해서 슬러리(slurry)상의 혼합수용액을 제조한다. 이 때, 사용되는 TiO2분말(36)은 Anatase결정상의 TiO2를 사용하며, 활성탄 대비 10~30wt%가 되도록 칭량해서 혼합한다.The inner wall of the lamp cover 32 is coated with a high adsorption / photocatalyst thin film as activated carbon and TiO 2 photocatalyst, which is a powder 35 formed by crushing ordinary palm activated carbon into fine particles (10 μm), The powder 36 obtained by atomizing titanium oxide having a photocatalytic activity is mixed well with water, a binder (TEG, etc.) to prepare a slurry-like mixed aqueous solution. At this time, the TiO 2 powder 36 to be used uses TiO 2 in the anatase crystal phase and is weighed and mixed so as to be 10-30 wt% with respect to activated carbon.
이와 같이 제조된 슬러리상의 혼합수용액을 램프 커버(32)의 내벽면에 분사시켜 5~10㎛정도의 코팅층을 형성한 후, 70~80℃의 열로 1~2시간동안 건조하면, 제5도에서 도시한 바와 같은 고비표면적 활성탄에 광촉매인 TiO2가 균일하게 분산된 고흡착/광촉매 산화분해기능을 갖는 코팅층이 형성되는 것으로, 이러한 TiO2광촉매의 제조과정을 제6도에 도시하였다.After spraying the slurry-like aqueous solution prepared on the inner wall surface of the lamp cover 32 to form a coating layer of about 5 ~ 10㎛, and dried for 1 to 2 hours with heat of 70 ~ 80 ℃, in Figure 5 A coating layer having a high adsorption / photocatalyst oxidative decomposition function in which TiO 2 as a photocatalyst is uniformly dispersed in a high specific surface area activated carbon as shown is formed, and the manufacturing process of the TiO 2 photocatalyst is shown in FIG.
한편, 상기 램프 커버(32)는 하부가 좁고, 상부로 갈수록 폭이 넓어지는 갓형상으로 형성하는 것이 바람직한 바, 이는 오염공기의 유입이 용이하게 이루어지고, 또한 자외선 램프(33)에서 발생되는 광이 램프 커버(32)의 내벽면에 형성되어 있는 고흡착/광촉매박막 전체에 균일하게 닿을 수 있도록 하려는 데 있다.On the other hand, the lamp cover 32 is preferably formed in the shape of a lampshade, the lower portion is narrower, the width becomes wider toward the upper side, which is easy to introduce contaminated air, and also the light generated from the ultraviolet lamp 33 This is to make it possible to uniformly contact the entire high adsorption / photocatalyst thin film formed on the inner wall surface of the lamp cover 32.
이와 같이 선도유지장치가 냉기의 귀환로인 냉장실 냉기 유입구에 설치되는 구성을 갖는 본 발명 냉장고는 냉동실과 냉장실을 순환한 후의 냉기가 다시 증발기로 귀환되어지는 위치에 설치되어 있기 때문에 냉장실 내의 오염공기가 통과되면서 탈취 및 살균이 이루어지게 됨으로써 고내에서 항시 신선한 공기가 순환되도록 하는 것이다.Thus, the refrigerator of the present invention having a configuration in which the lead holding device is installed in the refrigerating chamber cold air inlet which is the return path of the cold air is installed at the position where the cold air after circulating between the freezer compartment and the refrigerating compartment is returned to the evaporator. By passing through the deodorization and sterilization is to ensure that fresh air is circulated at all times.
이 때, 상기 선도유지장치에 유입되는 오염된 공기의 탈취 및 살균작용을 설명하면 다음과 같다.At this time, the deodorization and sterilization of the polluted air flowing into the lead holding device will be described.
선도유지장치의 하면에 형성되어 있는 냉기유입그릴(31a)로 오염된 공기가 유입되면, 램프 커버(32)의 내벽면에 코팅되어 있는 고흡착/광촉매 박막의 활성탄입자는 공기가 함유하고 있는 냄새 및 균을 흡착하게 되며, 이와 같이 활성탄 입자에 흡착된 냄새 및 균은 TiO2에 의해 광촉매 기능으로 산화분해되어 탈취 및 살균이 행해지게 된다.When the air contaminated by the cold air inlet grill 31a formed on the lower surface of the lead holding device is introduced, the activated carbon particles of the high adsorption / photocatalyst thin film coated on the inner wall surface of the lamp cover 32 are odors containing air. And the bacteria are adsorbed, and the odor and bacteria adsorbed on the activated carbon particles are oxidatively decomposed to the photocatalytic function by TiO 2 to be deodorized and sterilized.
상기 활성탄입자는 본래 활성탄 재질이 고비표면적의 특성을 갖음으로 해서 저온에서도 대부분의 냄새 및 균에 대해서 강력한 흡착특성을 갖는 효과가 있는 것이며, 상기 TiO2는 반도체이기 때문에 전기적 에너지 특히 광에너지가 가해지면 광을 흡수하여 여기됨으로써 전자와 정공이 생성되어 이와같이 생성된 전자와 정공이 표면으로 이동해서 표면이 전하분리상태가 되어 표면활성종을 생성하게 되고, 이렇게 생성된 표면활성종이 촉매기능을 수행함으로써 광촉매기능을 수행하게 된다.The activated carbon particles have an effect of having a high specific surface area of the activated carbon material, which has a strong adsorption characteristic against most odors and bacteria even at low temperatures, and since TiO 2 is a semiconductor, electrical energy, especially light energy, is applied. By absorbing and exciting light, electrons and holes are generated. The generated electrons and holes move to the surface, and the surface becomes charge-separated to generate surface-active species. The surface-active species thus produced perform a catalytic function. It will perform the function.
여기서, 상기 TiO2에서의 광흡수작용은 램프 커버(32)에 일측에 설치된 자외선 램프(33)로부터 발산되는 광에 의해 수행되는 것으로, 이 때의 자외선 램프(33)는 380nm이하의 광량을 갖는 백라이트 램프를 사용한다. 이러한 백라이트 램프를 사용하는 이유는 인체의 안전성 및 광촉매기능의 발휘측면을 고려한 것이다.Here, the light absorption in the TiO 2 is performed by the light emitted from the ultraviolet lamp 33 installed on one side of the lamp cover 32, the ultraviolet lamp 33 at this time has a light amount of less than 380nm Use a backlight lamp. The reason for using such a backlight lamp is to consider the aspects of the human safety and the photocatalytic function.
상기한 바와 같이 작용되는 본 발명 냉장고에서의 선도유지장치는 활성탄(35)과 TiO2박막(36)에 의해 주로 냄새와 균이 탈취 및 살균되며, 이러한 활성탄층의 강력한 흡착력과, TiO2층에서의 우수한 광촉매 기능으로 인해 흡착→광촉매산화분해→탈착의 순환사이클이 영구적으로 이루어져 선도유지장치를 교환해 줄 필요가 없는 장점이 있는 것이다.The freshness holding device in the refrigerator of the present invention which acts as described above is mainly deodorized and sterilized by activated carbon 35 and TiO 2 thin film 36, and the strong adsorption power of the activated carbon layer and the TiO 2 layer Due to its excellent photocatalytic function, the circulation cycle of adsorption → photocatalytic oxidation decomposition → desorption is permanent and there is no need to replace the leading maintenance device.
한편, 본 발명 냉장고의 탈취효과를 종래 냉장고와 비교하여 실험하였는 바, 제7도는 야채류의 부패취인 CH3SH에 대해 실험한 결과치이고, 제8도는 축육/생선류의 부패취인(CH3)3N에 대해 실험한 것으로, CH3SH에서는 약 5분정도 빨리 냄새 성분을 제거하였고, (CH3)3N인 경우에는 냄새의 50%를 제거하는데는 2배 빠른 시간에, 완전히 제거하는데는 종래 냉장고가 40%이상의 냄새가 잔존되고 있는 시간이 15분 내에 완전히 0냄새를 제거하는 정도의 효과를 보이고 있다.On the other hand, the deodorizing effect of the refrigerator of the present invention was compared with the conventional refrigerator, Figure 7 is a result of the experiment for the decayed CH 3 SH of vegetables, Figure 8 is a decayed odor of meat / fish (CH 3 ) 3 N In experiments, the odor component was removed about 5 minutes in CH 3 SH, and in the case of (CH 3 ) 3 N, twice as fast as 50% of the odor was removed, and the conventional refrigerator was completely removed. The time when more than 40% of odors remain is effective to remove odor completely within 15 minutes.
또한, 본 발명 냉장고의 살균효과에 대한 실험결과는 제9도와 제10도에 나타낸 바와 같은데, 제9도는 대장균에 대한 살균특성을, 제10도에서는 황색포도상구균에 대한 살균력을 보인 것으로, 종래 냉장고와 비교할 때 월등한 살균특성을 갖는 것임을 알 수 있다.In addition, the experimental results for the sterilization effect of the refrigerator of the present invention is shown in Figure 9 and 10, Figure 9 shows the bactericidal properties for E. coli, Figure 10 shows the bactericidal power against Staphylococcus aureus, conventional refrigerator It can be seen that it has superior sterilization characteristics when compared with.
이상에서 상세히 설명한 바와 같이 본 발명에 의한 냉장고는 냉기의 순환되어 다시 증발기로 귀환되는 경로에 선도유지장치를 설치함으로써 순환된 냉기속에 함유되어 있는 냄새성분을 탈취하고, 균들을 살균시키는 작용이 효과적으로 이루어지는 장점이 있고, 탈취 및 살균효과가 종래의 냉장고에 비해 현저하게 향상되도록 한 것이다.As described in detail above, the refrigerator according to the present invention deodorizes the odor component contained in the circulated cold air by effectively installing the lead holding device on the path of circulating the cold air and returning back to the evaporator, thereby effectively sterilizing the bacteria. There is an advantage, the deodorizing and sterilizing effect is to be significantly improved compared to the conventional refrigerator.
또한, 탈취 및 살균 후에 우수한 광촉매기능에 의해 계속적으로 산화분해되어 탈착되기 때문에 수명이 영구적으로 되어 장치를 교환해주지 않아도 되므로 소비자의 신뢰도를 향상시킨 것으로, 본 발명에 이용되는 선도유지장치는 냉장고 뿐 아니라 살균 및 탈취를 요하는 공조기기(에어콘, 공기청정기 등)에 응용이 가능하고, 조리기기에서의 탈취 및 탈연의 용도로도 사용가능하며, 특히 야채류, 어류, 축육류 등의 신선도를 요하는 보관식품의 저장고에 사용될 수 있다.In addition, since the oxidative decomposition and desorption by the excellent photocatalyst function after the deodorization and sterilization, the lifetime is permanent, so there is no need to replace the device to improve the reliability of the consumer, the leading maintenance device used in the present invention is not only a refrigerator It can be applied to air conditioning equipment (air conditioner, air purifier, etc.) that requires sterilization and deodorization, and can also be used for deodorization and deodorization in cooking equipment.In particular, it requires storage of freshness such as vegetables, fish, meat etc. It can be used in food storage.
