본 발명은 냉장고의 냉기토출구 위치가변장치에 관한 것으로, 특히 냉장고의 냉기토출구의 위치를 이동시키는 냉장고의 냉기토출구 위치가변장치에 관한 것이다.The present invention relates to a cold air discharge position variable device of the refrigerator, and more particularly to a cold air discharge position variable device of the refrigerator for moving the location of the cold air discharge port of the refrigerator.

일반적으로, 냉장고는 냉동사이클의 증발기에서 열교환된 냉기를 냉기공급덕트(101)를 통해 냉동실이나 냉장실로 공급함으로써 냉동실이나 냉장실을 냉각시키게 된다.In general, the refrigerator cools the freezing compartment or the refrigerating compartment by supplying cold air heat exchanged in the evaporator of the refrigerating cycle to the freezing compartment or the refrigerating compartment through the cold air supply duct 101.

냉동사이클은 압축기로 저온저압의 기체를 고온고압의 기체로 압축시키고, 상기 압축기를 통과한 고온고압의 기체를 응축기를 통해 상온의 고압액체로 응축시키며, 상기 응축기를 통과한 냉매를 팽창변을 통해 저온저압액체로 변화시킨 후 증발기를 통해 상기 팽창변으로부터 냉매를 공급받아 기화시킴으로써 냉기를 생성시키게 된다.The refrigeration cycle compresses low-temperature, low-pressure gas into high-temperature, high-pressure gas through a compressor, condenses the high-temperature, high-pressure gas passed through the compressor into a high-pressure liquid at room temperature through a condenser, and cools the refrigerant passing through the condenser through an expansion valve. After changing to a low-pressure liquid, the refrigerant is vaporized by receiving a refrigerant from the expansion valve through an evaporator to generate cold air.

냉장고의 냉동실이나 냉장실 일측벽에는 냉기공급덕트(101)로부터 냉동실이나 냉장실로 냉기를 토출시키는 다수개의 냉기토출구(110)가 상하방향으로 소정간격을 두고 구비되어 있고, 물건을 거취하는 다수개의 선반(102)이 상하방향으로 소정간격을 두고 위치이동가능하게 구비되어 있다.One side wall of the freezer compartment or the refrigerating compartment of the refrigerator has a plurality of cold air discharge outlets 110 for discharging cold air from the cold air supply duct 101 to the freezer compartment or the refrigerating compartment at predetermined intervals in the vertical direction, and a plurality of shelves for taking the article ( 102 is provided to be movable in the vertical direction at a predetermined interval.

통상적으로 냉기토출구(110)는 선반(102)의 저면에 인접하게 구비되어 선반(102)에 거취되는 물건의 상부로 냉기를 공급하게 되고, 위치가 고정되어 형성됨으로써 사용자가 보관물건의 크기에 따라 선반(102)의 위치를 서로 변경시키게 되면 경우에 따라 선반(102)이나 물건이 냉기토출구(110)를 가로막아 냉기가 토출되지 못하게 하는 문제점이 있었다.Typically, the cold air outlet 110 is provided adjacent to the bottom surface of the shelf 102 to supply cold air to the upper portion of the object taken on the shelf 102, the position is fixed is formed by the user according to the size of the storage When the positions of the shelf 102 are changed from each other, there is a problem that the shelf 102 or the object intercepts the cold air discharge port 110 to prevent cold air from being discharged.

즉, 선반(102)은 물건의 크기에 따라 다양하게 수용할 수 있도록 상하 선반(102)들의 사이 간격을 변경할 수 있으며 선반(102)의 형상도 달라 선반(102)의 위치를 임의로 변경할 경우 냉기토출구(110)를 차폐할 수 있다.That is, the shelf 102 may change the distance between the upper and lower shelves 102 so as to accommodate variously according to the size of the object, and the shape of the shelf 102 is different, so if the position of the shelf 102 is changed arbitrarily, the cold air discharge port 110 may be shielded.

이와 같이 일측 냉기토출구(110)가 막힐 경우 다른 냉기토출구(110)로 냉기가 집중되어 특정 음식물이 과냉될 수 있으며, 냉동실이나 냉장실 내의 온도가 균일하게 분포되지 않아 냉각효율을 저하시키게 되고, 그에 따라 보관중인 음식물이 부패될 수 있는 문제점이 있었다.As such, when one side of the cold air outlet 110 is blocked, the cold air is concentrated in the other cold air outlet 110 so that certain foods may be supercooled, and thus the cooling efficiency is not uniformly distributed in the freezing compartment or the refrigerating compartment, thereby decreasing the cooling efficiency. There was a problem that the food in storage can be corrupted.

또한, 도 1에 도시된 바와 같이 상측선반(SU)을 SU"로 하향이동하고, 하측선반(SL)을 SL'로 상향이동하는 경우, 중간의 공간(b)으로는 냉기가 토출되지 못하게 되므로 음식물이 정상적으로 냉각되지 못하는 문제점이 있었다.In addition, as shown in FIG. 1, when the upper shelf SU is moved downward to SU ″ and the lower shelf SL is upwardly moved to SL ′, cold air is not discharged to the intermediate space b. There was a problem that the food is not cooled normally.

이에 본 발명은 상기한 바의 제반 문제점들을 해소하기 위해 안출된 것으로, 냉동실이나 냉장실내의 냉기토출구의 위치를 가변시킴으로써 선반이나 보관물건에 의해 토출구가 막히는 것을 방지하여 냉동실이나 냉장실내의 온도분포를 균일하게 유지하고 냉각효율을 높일 수 있는 냉장고의 냉기토출구 위치가변장치를 제공함에 그 목적이 있다.
Accordingly, the present invention has been made to solve the above problems, by changing the position of the cold air outlet in the freezer compartment or the refrigerating compartment to prevent the discharge port is blocked by the shelf or storage items to prevent the temperature distribution in the freezer compartment or the refrigerating compartment. It is an object of the present invention to provide a variable location of the cold air outlet of the refrigerator that can be maintained uniformly and increase the cooling efficiency.

상기한 바의 목적을 달성하기 위한 본 발명은, 냉장고의 증발기로부터 냉기공급덕트를 통해 냉동실이나 냉장실 내부로 냉기를 공급하는 냉기토출구의 일측에 위치이동가능하게 구비되고 상기 냉기토출구의 일부를 개폐하는 개폐기구와, 상기 개폐기구를 강제로 작동시키는 개폐기구 구동수단을 포함하고 있다.The present invention for achieving the above object is provided to be movable on one side of the cold air discharge port for supplying cold air into the freezer compartment or the refrigerating compartment through the cold air supply duct from the evaporator of the refrigerator and to open and close a part of the cold air outlet. And a switchgear driving means for forcibly operating the switchgear.

상기 냉기토출구는 다수개의 선반이 배열되는 수평 방향을 가로지르는 방향을 따라 장형으로 형성되거나, 다수개의 개구부가 전체적으로 방사형으로 구분되어 형성될 수 있다.The cold air discharge port may be formed in a long shape along a direction crossing a horizontal direction in which a plurality of shelves are arranged, or a plurality of openings may be formed in a radial manner.

상기 개폐기구는 다수개의 선반이 배열되는 수평 방향을 가로지르는 방향으로 슬라이드가능하게 구비될 수 있고, 상기 냉기토출구의 일측에 축회전가능하게 구비될 수 있다.The opening and closing mechanism may be slidably provided in a direction crossing a horizontal direction in which a plurality of shelves are arranged, and may be rotatably provided on one side of the cold air discharge port.

상기 개폐기구 구동수단은 래크와 피니언 및, 상기 피니언을 구동시키는 구동모터로 구성되는 것이 바람직하다.The opening and closing mechanism driving means is preferably composed of a rack and pinion, and a drive motor for driving the pinion.
