이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 따른 냉장실 냉기공급장치의 구조도이다.2 is a structural diagram of a refrigerator compartment cold air supply device according to the present invention.

상기한 도면에서 나타낸 바와 같이 주냉기덕트(16)의 하부에 냉장실의 각 위치로 분기된 냉기덕트(22)의 분기 위치에 냉장실 송풍기(26)를 설치한다.As shown in the above figure, the refrigerator compartment blower 26 is installed in the branch position of the cold air duct 22 branched to each position of the refrigerator compartment in the lower part of the main cold air duct 16. As shown in FIG.

도면 제3도에서 도시한 바와 같이 상기 냉장실 송풍기(26)의 전방은 관통되어 육명실(20)로 냉기를 공급하는 육명실 냉기토출구(20a)가 형성되고, 냉장실 송풍기(26)의 후측에는 냉장실의 후측 중앙부에 세로로 형성된 냉기덕트(22)의 입구부(22a)가 위치하며, 냉장실 양측에는 양 사이드덕트(23)(24)의 입구부(23a)(24b)가 위치한다.As shown in FIG. 3, the front side of the refrigerating chamber blower 26 is formed therein, and a cooling chamber air discharge outlet 20a for supplying cold air to the six chambers 20 is formed, and a refrigerating chamber at the rear side of the refrigerating chamber blower 26. The inlet portion 22a of the cold air duct 22 formed vertically in the rear center portion of the rear portion is located, and the inlet portions 23a and 24b of both side ducts 23 and 24 are positioned on both sides of the refrigerating chamber.

그리고 상기 각 입구부(22a)(23a)(24a)에는 냉장실 송풍기(26)에 의해 토출되는 냉기를 유도하기 위한 냉기 가이드편(22b)(23b)(24b)이 각각 형성되어 있다.In each of the inlets 22a, 23a, 24a, cold air guide pieces 22b, 23b, 24b for inducing cold air discharged by the refrigerating chamber blower 26 are formed, respectively.

또한 도면 제2도, 제3도에서와 같이 상기 냉장실 송풍기(26)는 축방향으로 형성된 날개(26a)가 회전축(26b)의 외부에 다수개 형성되어 축방향에서 냉기를 흡입하여 외측방으로 냉기를 토출시키는 원심송풍기가 적용된다.2 and 3, the refrigerating chamber blower 26 has a plurality of wings 26a formed in the axial direction formed outside the rotating shaft 26b to suck cold air in the axial direction and to cool the outside air. A centrifugal blower for discharging is applied.

또한 도면 제4도에서 나타낸 바와 같이 주냉기덕트(16)의 입구부(16a)를 증발기(12)의 중간부에서 인출시켜 증발기(12)의 중간부를 통과한 냉기를 냉동실로 공급할 수도 있다.In addition, as shown in FIG. 4, the inlet portion 16a of the main cold air duct 16 may be taken out from the middle of the evaporator 12 to supply the cold air passing through the middle of the evaporator 12 to the freezing chamber.

상기와 같은 구조에 의한 작동관계를 살펴보면 다음과 같다.Looking at the operation relationship by the above structure as follows.

먼저 냉동실 송풍기(14a)와 냉장실 송풍기(26)가 작동하여 냉동실 및 냉장실내부의 온기를 순환시키면 온기는 각 귀환덕트(10a)(10b)를 통해 증발기(12)를 통과하게 되며 통과된 온기는 온도를 빼앗겨 냉기로 변환된다.First, when the freezer compartment blower 14a and the refrigerating compartment blower 26 operate to circulate the warmth in the freezer compartment and the refrigerating compartment, the warmer passes through the evaporator 12 through the respective return ducts 10a and 10b, and the warmed temperature is passed through. It is taken away and converted to cold.

이와 같이 형성된 냉기는 일부는 냉동실 송풍기(14a)에 의해 냉동실로 공급되고, 다른 일부는 주냉기덕트(16)의 하부에 위치한 냉장실 송풍기(26)의 작동에 의해 주냉기덕트(16)를 통해 냉장실 송풍기(26)로 관류하게 되며, 뒤이어 냉기덕트(22)와 사이드덕트(23)(24)로 분할공급되어 냉장실로 토출된다.The cold air formed as described above is partially supplied to the freezing chamber by the freezer compartment blower 14a, and the other part is operated by the refrigerating compartment blower 26 located below the main cold air duct 16 through the main cold air duct 16. It flows through the blower 26, and is dividedly supplied to the cold air duct 22 and the side ducts 23, 24 and discharged to the refrigerating chamber.

이때 주냉기덕트(16)에서 냉장실 송풍기(26)로 흡입된 냉기는 도면 제3도에서와 같이 냉장실 송풍기(26)의 중심부로 흡입되어 외부 사방으로 토출되는데, 토출되는 냉기는 냉기덕트(22)와 사이드덕트(23)(24)의 입구부(22a)(23a)(24a)에 형성된 가이드(22b)(23b)(24b)에 유도되어 유입되어 냉장실로 공급되며, 일부는 육명실 냉기토출구(20a)를 통해 냉장실의 상부에 위치한 육명실 냉기토출구(20a)로 토출된다.At this time, the cold air sucked into the refrigerating chamber blower 26 from the main cold air duct 16 is sucked into the center of the refrigerating chamber blower 26 and discharged to the outside in all directions as shown in FIG. 3, and the discharged cold air is the cold air duct 22. And guides 22b, 23b, and 24b formed at the inlets 22a, 23a, and 24a of the side ducts 23 and 24, are introduced into the refrigerator compartment, and some of them are supplied to the cold room air outlet ( Through the 20a) is discharged to the cooling chamber air outlet 20a located in the upper portion of the refrigerating chamber.

한편 도면 제4도는 본 발명의 다른 실시예를 나타낸 냉장실 냉기공급장치 구조도로써, 주냉기덕트(16)의 입구부(16a)를 증발기(12)의 중간부에 위치시키게 되면 주냉기덕트(16)의 길이가 짧아지게 되어 재료가 절감됨과 동시에 이를 통과하는 냉기의 저항도 줄일 수 있어 효과적이며, 증발기(12)를 완전 통과한 냉기의 온도가 증발기(12)의 중간부분을 통과한 냉기와의 온도차는 미소하므로 중간부에서 냉기를 흡입하더라도 냉장실의 냉각작용을 충분히 이행할 수 있다.4 is a structure diagram of a refrigerator compartment cold air supply device showing another embodiment of the present invention. When the inlet portion 16a of the main cold air duct 16 is positioned in the middle of the evaporator 12, the main cold air duct 16 is shown. It is effective to shorten the length of the material and to reduce the resistance of the cold air passing through it, which is effective, and the temperature difference between the cold air passing through the evaporator 12 and the cold part passing through the middle part of the evaporator 12 Because of the small amount, even if cold air is sucked in the middle portion, the cooling operation of the refrigerating compartment can be sufficiently performed.

아울러 상기 냉장실 송풍기(26)의 위치도 냉동실과 냉장실의 중간에 위치되어 냉기덕트(22) 및 사이드덕트(23)(24)를 통해 냉장실로 공급시키는 냉기의 압송거리가 짧아지고, 냉장실 송풍기(26)를 송풍력이 좋은 원심송풍기를 사용함에 따라 냉장실에 냉기의 유입이 더욱더 효과적으로 이루어진다.In addition, the location of the refrigerating chamber blower 26 is also located in the middle of the freezer compartment and the refrigerating compartment to shorten the feeding distance of the cold air to be supplied to the refrigerating chamber through the cold air duct 22 and the side ducts 23 and 24, and the cold room blower 26 By using centrifugal blower with good blowing power, the inflow of cold air into the refrigerating chamber becomes more effective.

이상에서 살펴본 바와 같이 본 발명은 냉장실 송풍팬을 냉동실과 냉장실의 중간부에 위치시켜 냉기의 유입과 이를 냉장실로 압송하는 압송거리를 줄이고, 주냉기덕트의 입구를 증발기의 중간부에서 인출시킴에 따라 주냉기덕트의 길이를 짧게함과 동시에 냉장실 송풍팬을 송풍력이 좋은 원심송풍팬을 적용시키므로 냉장실에 냉기의 공급이 효율적으로 이루어지게 하고, 재료의 절감에 의한 원가를 낮출수 있는 특출한 발명이다.As described above, the present invention reduces the inflow of cold air and the feeding distance for transporting the cold air into the refrigerating chamber by placing the refrigerating chamber blowing fan in the middle of the freezer compartment and the refrigerating compartment, and drawing the inlet of the main cold air duct from the middle of the evaporator. It is a special invention that shortens the length of the main cold duct and at the same time applies a centrifugal blower with a high blowing power to the refrigerating compartment blowing fan, thereby efficiently supplying the cold air to the refrigerating compartment and lowering the cost of material savings. .
