본 고안은 냉장고에 관한 것으로, 더욱 상세하게는 보관되는 음식물의 특성과 양에 따라서 저장실이 적정온도를 유지하도록 냉기량을 조절하여 저장실의 기능을 냉동실, 싱싱고, 냉장실, 야채실 등 선택적으로 절환할 수 있도록 하는 냉장고의 냉기공급조절장치에 관한 것이다.The present invention relates to a refrigerator, and more particularly, it is possible to selectively change the function of the storage compartment by freezing, sinking, refrigerating, and vegetable compartment by adjusting the amount of cold air to maintain the proper temperature according to the characteristics and quantity of food stored. It relates to a cold air supply control device of the refrigerator.

일반적으로 냉장고는 각종 식품을 냉동 및 냉장상태로 저장하여 장기간 신선도를 유지하는데 사용되는 것이다. 이러한 기능을 하는 통상적인 냉장고는 통상 상, 하 구획되어 상측에 각종 음식물을 냉동시키거나 선택적으로 기능을 절환하여 냉장상태로 보관할 수 있는 냉동실이 구비되고, 하측에 다단으로 구획된 냉장실이 구비되어 있으며, 냉동실과 냉장실은 각각의 도어에 의해 밀폐된다.In general, a refrigerator is used to store various foods in a frozen and refrigerated state to maintain freshness for a long time. A conventional refrigerator having such a function is usually provided with a freezer compartment which is divided into upper and lower parts to freeze various foods on the upper side or to selectively store functions in a refrigerated state, and has a refrigerator compartment partitioned into multiple stages at the lower side. The freezer compartment and the refrigerating compartment are sealed by respective doors.

제1도는 일반적인 냉장고의 냉장실 도어를 생략하여 냉장실을 보인 정면구성도이다. 냉장고는 이에 도시한 바와 같이, 냉장실(100)의 내부 후방에 냉기공급카바(200)가 설치되며, 냉기공급카바(200)의 적소에는 다수의 냉기토출구(210)가 구비되어 냉장실(100) 내부로 냉기가 공급된다.1 is a front configuration diagram showing a refrigerator compartment by omitting the refrigerator compartment door of a typical refrigerator. As illustrated in the refrigerator, a cold air supply cover 200 is installed at an inner rear of the refrigerating compartment 100, and a plurality of cold air discharge ports 210 are provided at a proper location of the cold air supply cover 200. Cold air is supplied to the furnace.

그러나 일반적인 냉장고에서 냉기가 공급되는 다수개의 냉기토출구(210)는 항상 일정한 크기를 갖고 개방된 상태이므로 냉장실(100)에 보관된 음식물의 양 또는 특성에 따라 변하는 적정온도를 유지할 수 없어 보관된 음식물의 신선도가 저하되는 문제점이 발생된다.However, since a plurality of cold air outlet 210 supplied with cold air in a general refrigerator is always in a constant size and is open, it is not possible to maintain an appropriate temperature that varies depending on the amount or characteristics of the food stored in the refrigerating chamber 100 of the stored food. There is a problem that the freshness is reduced.

좀 더 구체적으로는 냉장실(100)에 보관된 음식물이 밀가루, 과자, 야채, 생선 등 각각 다른 온도와 습도를 요하는 음식물이 보관된 상태에서는 보관된 음식물의 특성에 알맞는 적정온도를 유지해야 하는데, 냉기토출구(210)를 통하여 냉장실(100) 내로 공급되는 냉기는 항상 균일하고 지속적으로 공급되므로 보관된 음식물의 특성에 따른 적정온도를 유지할 수 없어 오히려 음식물의 맛을 저하시키는 문제점이 있다.More specifically, the food stored in the refrigerating chamber 100 must maintain a proper temperature suitable for the characteristics of the stored food in a state in which foods requiring different temperatures and humidity, such as flour, sweets, vegetables, and fish, are stored. , Since the cold air supplied into the refrigerating chamber 100 through the cold air outlet 210 is always uniformly and continuously supplied, it is not possible to maintain a proper temperature according to the characteristics of the stored food, but rather reduces the taste of the food.

본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 보관되는 음식물의 특성과 양에 따라 저장실로 유입되는 냉기량을 선택적으로 조절하여 저장실을 냉동실, 싱싱고, 냉장실, 야채실 등 선택적으로 기능을 절환함으로써, 적정온도를 유지시키면서 사용할 수 있는 냉장고의 냉기공급조절장치를 제공하는 것이다.The present invention is to solve this problem, the purpose of the present invention is to selectively control the amount of cold air flowing into the storage room according to the characteristics and the amount of food to be stored selectively functioning the storage room, such as a freezer, a sink, a refrigerator, a vegetable room, etc. By switching the, to provide a cold air supply control device of the refrigerator that can be used while maintaining the proper temperature.

이러한 목적을 달성하기 위한 본 고안은, 저장실로 냉기가 공급되도록 냉기토출구가 형성된 냉기공급카바를 갖춘 냉장고에 있어서, 냉기토출구를 선택적으로 개폐하여 저장실 내로 유입되는 냉기량을 조절하는 밀폐수단, 냉기토출구의 상, 하측에 대향 설치되어 밀폐수단의 개폐이동을 안내하는 안내수단을 구비하는 것을 특징으로 한다.The present invention for achieving the above object, in the refrigerator having a cold air supply cover formed with a cold air discharge port to supply cold air to the storage compartment, the sealing means for selectively opening and closing the cold air outlet to control the amount of cold air flowing into the storage compartment, cold air outlet It is characterized in that it is provided on the upper and lower sides of the guide means for guiding the opening and closing movement of the sealing means.

이하에서는 본 고안에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다. 제2도와 제3도는 본 고안에 따른 냉기공급 조절장치의 구조와 작동상태를 보인 것이다. (본 고안에 따른 냉기공급 조절장치는 통상적인 냉장고에 적용되기 때문에 냉장고의 일반적인 구조에 대해서는 제1도를 참조한다)Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 2 and 3 show the structure and operating state of the cold air supply control device according to the present invention. (Refer to Figure 1 for the general structure of the refrigerator because the cold air supply control device according to the present invention is applied to a conventional refrigerator)

냉장고는 일반적으로 식품을 보관하는 저장실이 중간격벽에 의해 냉동실과 냉장실로 구획되어 있으며, 냉장식품을 저장하는 저장실은 가로방향으로 설치되어 음식물이 수납되는 선반에 의해 칸칸으로 구분되어 있다.In the refrigerator, a storage compartment for storing food is generally divided into a freezer compartment and a refrigerating compartment by an intermediate partition, and a storage compartment for storing refrigerated food is divided into compartments by shelves in which food is stored in a horizontal direction.

그리고 이러한 냉장식품을 저장하는 저장실의 후측 벽면에는 냉기공급카바가 마련되며, 여기에는 칸칸으로 냉기가 토출되는 다수개의 냉기토출구가 형성되어 있다. 또한 냉기토출구에는 본 고안의 특징적인 요소로 냉장실에 보관되는 음식물의 특성에 따른 냉기량을 조절하는 냉기공급 조절장치가 설치되어 있다.And a cold air supply cover is provided on the rear wall of the storage compartment for storing the refrigerated food, there are formed a plurality of cold air discharge outlets for discharging the cold air into the compartment. In addition, the cold air discharge outlet is installed as a characteristic element of the present invention is a cold air supply control device for adjusting the amount of cold air according to the characteristics of the food stored in the refrigerator compartment.

본 고안에 따른 냉기공급 조절장치는 제2도와 제3도에 도시한 바와 같이, 냉기토출구(210A) 상부와 하부에 각각 구성된 안내수단(1,1',1'',1'''), 안내수단(1,1',1'',1''')을 따라 슬라이딩 이동되어 냉기토출구(210A)를 개폐하는 밀폐수단(2,2',2'',2''')으로 이루어져 있다.The cold air supply control device according to the present invention, as shown in Figure 2 and 3, the guide means (1,1 ', 1' ', 1' '') respectively configured on the upper and lower portions of the cold air outlet 210A, Sliding movement along the guide means (1,1 ', 1' ', 1' '') is made of a closed means (2,2 ', 2' ', 2' '') for opening and closing the cold air outlet 210A. .

안내수단(1)은 동일한 수평선상을 유지하는 냉기토출구(210A)의 상측전장에 걸쳐서 일체로 설치되며 선단부가 하향 절곡된 상부안내레일(10)과 냉기토출구(210A)의 하측전장에 걸쳐서 일체로 마련되며 상부안내레일(10)과 대향되도록 선단부가 상향 절곡된 하부안내레일(11)로 구성되어 있다. 한편, 이 안내수단(1)은 칸칸마다 형성된 냉기토출구(210A)에 모두 동일한 형상으로 마련되어 있기 때문에, 다른 안내수단(1,1',1'',1''')에 대한 별도의 설명은 생략한다.The guide means 1 is integrally installed over the upper electric field of the cold air discharge port 210A maintaining the same horizontal line, and integrally over the lower electric field of the upper guide rail 10 and the cold air discharge port 210A whose tip portions are bent downward. It is provided and consists of a lower guide rail 11, the tip portion is bent upward to face the upper guide rail (10). On the other hand, since the guide means 1 are all provided in the same shape in the cold air outlet 210A formed for each compartment, a separate description for the other guide means (1,1 ', 1' ', 1' '') Omit.

그리고 밀폐수단(2)은 안내수단(1)의 상부안내레일(10)과 하부안내레일(11) 사이에 좌, 우로 슬라이딩 가능하게 끼워져 결합되어 냉기토출구(210A)의 개방정도를 조절함으로써 냉기 유입량을 제어하는데, 이의 구조는 다음과 같다.The sealing means 2 is slidably inserted between the upper guide rail 10 and the lower guide rail 11 of the guide means 1 to the left and right to adjust the degree of opening of the cold air outlet 210A by adjusting the opening degree of the cold air inlet. Its structure is as follows.

밀폐수단(2)은 상하측 단부가 상부안내레일(10)과 하부안내레일(11)에 끼워져 결합되는 사각판체형상의 개폐판(20)으로 구성되어 있으며, 이의 양측부에는 냉기토출구(210A)와 상응하게 개구되어 서로 연통되는 개구부(21''')가 천공되어 있다.Sealing means (2) is composed of a rectangular plate-shaped opening and closing plate 20 is coupled to the upper and lower end is fitted to the upper guide rail (10) and the lower guide rail (11), both sides of the cold air outlet 210A Openings 21 ′ ″ corresponding to and in communication with each other are perforated.

결국, 개폐판(20)으로 이루어진 밀폐수단(2)은 냉기토출구(210A)에 대해 수평선상에 설치된 안내수단(1)에 슬라이딩 가능하게 설치됨으로써, 개폐판(20)의 이동에 따라 냉기토출구(210A)의 연통 정도가 가변된다.As a result, the sealing means (2) consisting of the opening and closing plate 20 is slidably installed in the guide means (1) provided on the horizontal line with respect to the cold air outlet 210A, the cold air outlet ( The degree of communication of 210A) is variable.

한편, 다른 밀폐수단(2,2',2'',2''')의 구조는 앞에서 설명한 밀폐수단(2)과 동일하기 때문에 이에 대한 별도의 설명은 생략한다.On the other hand, since the structure of the other sealing means (2, 2 ', 2' ', 2' '') is the same as the sealing means (2) described above, a separate description thereof will be omitted.

다음에는 이와 같이 구성된 냉기공급 조절장치의 작용 및 효과를 첨부도면을 참조하여 설명하는데, 설명의 편의를 위해 종래와 동일한 부분, 부재에 대해서는 A를 부가한 동일부재번호를 사용한다.Next, the operation and effect of the cold air supply control device configured as described above will be described with reference to the accompanying drawings. For convenience of description, the same part number and the same member number with A are used for the same parts and members.

제3a, 3b, 3c, 3d도는 각각 본 고안의 사용상태를 보인 구성도인데, 제3a도의 상태에서는 냉기토출구(210A)와 이의 개구정도를 선택적으로 조절하는 개폐판(20)의 개구부(21''')가 완전히 일치 개방되어 저장실로 유입되는 냉기량이 극대화됨으로써, 저장실 전체가 냉동식품을 보관하는 냉동실 상태로 기능절환된 상태라 할 수 있다.3a, 3b, 3c, 3d is a configuration diagram showing the use state of the present invention, respectively, in the state of Figure 3a the opening 21 'of the opening and closing plate 20 to selectively control the cold air outlet 210A and its opening degree '') Is completely coincidentally open, maximizing the amount of cold air flowing into the storage compartment, and thus the entire storage compartment may be functionally switched to a freezer compartment for storing frozen food.

제3b도는 개폐판(20)을 우측으로 d1의 길이만큼 이동시킨 것을 도시한 것으로, 개구부(21''')와 냉기토출구(210A)가 약간 어긋나고 냉기토출구(210A)의 개구정도가 약간 줄어들게 됨으로써, 저장실로 유입되는 냉기량이 조금 감소된다. 이에 따라 저장실은 싱싱고 상태로 유지된다. 이 때, d1, d2, d3는 개폐판(20)의 이동거리를 표시한 것으로, d3의 길이가 가장 길며, 그 다음 d2, d1 순이다.3b shows that the opening and closing plate 20 is moved to the right by the length of d1, and the opening 21 '' 'and the cold air outlet 210A are slightly displaced, and the opening degree of the cold air outlet 210A is slightly reduced. As a result, the amount of cold air flowing into the storage compartment is slightly reduced. As a result, the storage compartment is kept in a fresh state. At this time, d1, d2 and d3 indicate the moving distance of the opening and closing plate 20, the length of d3 is the longest, and then d2, d1 in order.

그리고 제3c도의 상태는 제3b도의 상태보다 개폐판(20)을 d2의 길이만큼 우측으로 이동시킨 것을 보인 것으로, 이러한 경우에는 냉기토출구(210A)가 개폐판(20)에 의해 조금 더 폐쇄되어 앞에서 설명한 싱싱고 상태보다 냉기의 유입량이 줄어들게 됨으로써, 냉장실 상태로 유지된다.The state of FIG. 3c shows that the opening and closing plate 20 is moved to the right by the length of d2 than the state of FIG. 3b. In this case, the cold air outlet 210A is closed by the opening and closing plate 20 a little longer. Since the inflow rate of cold air is reduced rather than the described singego state, it is maintained in the refrigerator compartment state.

제3d도의 상태는 제3c도의 상태보다 개폐판(20)을 d3의 길이만큼, 즉 d2의 길이보다 더욱 우측으로 이동하여 개구부(21''')일측의 개폐판(20)이 냉기토출구(210A)를 더욱 폐쇄한 것을 나타낸 것으로, 냉장실 상태보다 냉기의 유입량이 더욱 감소되어 야채실 상태로 유지된다.In the state of FIG. 3d, the opening and closing plate 20 is moved to the right by more than the length of d3, that is, the length of d2, than the state of FIG. 3c, so that the opening and closing plate 20 on one side of the opening 21 ′ ″ is cold air outlet 210A. ) Is further closed, and the inflow rate of cold air is further reduced than in the refrigerator compartment, and is maintained in the vegetable compartment.

한편, 다수개의 안내수단(1,1',1'',1''')과 이에 설치되는 밀폐수단(2,2',2'',2''')이 모두 동일하게 구성되어 있기 때문에, 4개로 구성된 개폐판(20,20',20'',20''')이 전부 동일한 거리만큼 이동하여 동일한 상태를 유지해야만 저장실 전체의 기능을 냉동실, 싱싱고, 냉장실, 야채실 상태로 기능이 절환된다.On the other hand, since the plurality of guide means (1,1 ', 1' ', 1' '') and the sealing means (2,2 ', 2' ', 2' '') installed therein are all configured identically. The function of the entire storage compartment is changed to the freezer, sinking, refrigeration room, and vegetable room only when the four open / close boards 20, 20 ', 20' 'and 20' '' are kept in the same state by moving the same distance. It is switched.

즉 저장실 전체를 냉동실로 절환 사용할 때에는 4개의 개폐판(20,20',20'',20''') 모두를 제3a도의 상태로 유지하여 사용하고, 싱싱고로 절환사용하는 경우에는 4개의 개폐판(20,20',20'',20''')을 d1의 거리만큼 우측으로 이동 제3b도의 상태로 유지 사용한다. 그리고 냉장실 및 야채실로 절환 사용할 때에는 4개의 개폐판(20,20',20'',20''')을 d2 또는 d3만큼 이동시켜 제3c, 3d도의 상태로 유지 사용한다.In other words, when the entire storage compartment is used as a freezer compartment, all four open / close boards 20, 20 ', 20' ', 20' '' are kept in the state of FIG. The plates 20, 20 ', 20 ", 20' " are moved to the right by a distance of d1. When switching to the refrigerator compartment and the vegetable compartment, the four open / close boards 20, 20 ', 20 ", 20' " are moved by d2 or d3 to be maintained in the state of 3c and 3d.

또한 저장실이 냉장실, 싱싱고, 특선실, 야채실로 구획된 냉장고의 경우, 예를 들어 싱싱고 측으로만 냉기가 유입되는 냉기토출구(210A)의 개방량을 조절하면 싱싱고를 앞에서 설명한 바와 같이 냉동실 또는 야채실 등으로 기능을 절환할 수 있다.In addition, in the case where the storage compartment is divided into a refrigerating compartment, a sinking room, a specialty room, and a vegetable room, for example, by adjusting the opening amount of the cold air outlet 210A through which cold air flows only to the side of the sinking, the freezing room or the vegetable room is described. Function can be switched.

이와 같이 본 고안에 따른 냉기공급 조절장치는 냉기의 유입량을 선택적으로 조절하며 저장실의 기능을 절환하여 사용하는데, 냉기가 공급되는 다수개의 냉기토출구(210A)가 일정한 크기를 갖고 개방되어 저장실에는 냉기가 항상 균일하게 공급된다. 이에 따라 저장실에 보관된 음식물의 특성에 따라 적정온도를 유지할 수 있기 때문에 음식물의 맛과 신선도가 저하되는 것이 방지된다.As described above, the cold air supply control device according to the present invention selectively controls the inflow of cold air and uses the storage room to switch the function. The plurality of cold air discharge ports 210A to which the cold air is supplied have a predetermined size, and thus the cold air is stored in the storage room. It is always supplied evenly. Accordingly, since the proper temperature can be maintained according to the characteristics of the food stored in the storage compartment, the taste and freshness of the food are prevented from being lowered.

이상에서 상세히 설명한 바와 같이, 본 고안에 따른 냉장고의 냉기공급 조절장치는 냉기토출구의 개방정도를 제어하는 개폐판을 설치하여 저장실에 보관되는 음식물의 특성과 양에 따라서 유입되는 냉기량을 조절하였다. 따라서 저장실의 기능을 냉동실, 싱싱고, 냉장실, 야채실 등 기능 절환사용함으로써, 음식물의 신선도를 장기간 유지하며, 제품의 신뢰성이 향상되는 이점이 있다.As described above in detail, the cold air supply control device of the refrigerator according to the present invention was installed by the opening and closing plate to control the opening degree of the cold air outlet to adjust the amount of cold air introduced in accordance with the characteristics and the amount of food stored in the storage compartment. Therefore, by switching the function of the storage compartment, such as the freezer compartment, crispy, refrigerator compartment, vegetable compartment, there is an advantage to maintain the freshness of the food for a long time, and improve the reliability of the product.
