Description

냉장고의 냉기 공급구조Cold air supply structure of the refrigerator

본 발명은 냉장고의 냉기공급구조에 관한 것으로, 더욱 상세하게는 냉장실로 공급되는 냉기의 일부를 냉장실 하부의 야채실을 통하여 도어로 유도하여, 도어에서 후방으로 냉기를 공급할 수 있도록 구성되는 냉기공급구조에 관한 것이다.The present invention relates to a cold air supply structure of a refrigerator, and more particularly, to a cold air supply structure configured to guide a part of the cold air supplied to the refrigerating compartment through a vegetable compartment under the refrigerating compartment to supply cold air from the door to the rear. It is about.

먼저 제1도 참조하면서 종래의 냉장고의 구조 및 냉기공급을 위한 구조에 대하여 살펴보기로 한다.First, referring to FIG. 1, a structure of a conventional refrigerator and a structure for supplying cold air will be described.

도시된 바와 같이, 냉장고의 내부는, 단열재가 충진된 베리어(5)에 의하여 냉동실(2)과 냉장실(4)로 나누어져 있다. 그리고 상기 냉동실(2) 및 냉장실(4)은 각각 도어에 의하여 개폐될 수 있도록 되어 있고, 냉동실(2) 도어(14)의 내측에는 음식물을 보관하기 위한 도어바스켓(14a)이 다단으로 설치되어 있다.As shown, the inside of the refrigerator is divided into a freezer compartment 2 and a refrigerating compartment 4 by a barrier 5 filled with insulation. The freezer compartment 2 and the refrigerating compartment 4 are each opened and closed by a door, and a door basket 14a for storing food is provided in multiple stages inside the door 14 of the freezer compartment 2. .

냉기의 공급구조를 살펴보면, 저온 저압의 냉매가 내부를 통과하는 증발기(6)에서 열교환된 냉기의 일부는, 송풍팬(8)에 의하여 냉동실(2)로 공급되고, 나머지 일부는 자유 낙하하여 냉동실(4)로 공급된다. 냉장실(4)로의 냉기의 공급은, 냉장실 후방에 길이 방향으로 설치되어 있는 냉장실덕트(10)를 통하여 자유낙하하면서, 상기 냉장실덕트(10)의 전면에 형성되어 있는 다수개의 냉기토출구(10a)를 통하여 냉장고의 후방에서 전방을 향하여 냉기가 토출되도록 구성되어 있다.Looking at the supply structure of the cold air, part of the cold air heat-exchanged in the evaporator 6 through which the low-temperature low-pressure refrigerant passes inside is supplied to the freezer compartment 2 by the blower fan 8, and the other part is free-falled to freezer compartment. It is supplied to (4). The supply of the cold air to the refrigerating chamber 4 freely falls through the refrigerating chamber duct 10 provided in the longitudinal direction at the rear of the refrigerating chamber, while opening the plurality of cold air discharge ports 10a formed on the front surface of the refrigerating chamber duct 10. Through the cold air is discharged from the rear of the refrigerator toward the front.

이와 같은 과정을 통하여 냉동실(2) 및 냉장실(4)로 공급된 냉기는 내부에 보관중인 식품과의 열교환 과정을 거쳐 상대적으로 고온으로 되고, 고온으로 된 공기는 베리어(5)의 내부에 성형된 냉동실귀환덕트(도시 생략) 및 냉장실귀환덕트(4a)를 통하여 다시 증발기(6) 부근으로 이동하게 된다.The cold air supplied to the freezer compartment 2 and the refrigerating compartment 4 through this process becomes relatively high temperature through heat exchange with the food stored therein, and the air having a high temperature is formed inside the barrier 5. The freezing chamber return duct (not shown) and the refrigerating chamber return duct 4a move to the vicinity of the evaporator 6 again.

이와 같은 냉기공급구조에 있어서, 냉동실은 통상 그 체적이 작기 때문에 심각한 문제로 대두되지 않지만, 내부 체적인 큰 냉장실(4)은 냉기의 전체적인 순환이 문제가 된다. 즉 상술한 바와 같이, 냉기가 후방에서 전방으로의 일방향으로만 공급되고 있기 때문에 전체적으로 균일한 냉장효과를 달성하기 못하는 문제점이 지적되는 것이다.In such a cold air supply structure, the freezer compartment is not a serious problem because of its small volume, but the large circulation compartment 4 of the internal volume is a problem of the overall circulation of the cold air. That is, as described above, since the cold air is supplied only in one direction from the rear to the front, it is pointed out that the overall refrigeration effect cannot be achieved.

따라서 냉기의 공급원과 가장 이격된 위치인 도어측에는 충분하게 냉기가 공급되지 못하기 때문에, 냉기토출공(10a)와 인접하게 놓인 음식물은 과냉되고, 도어측에 위치한 음식물은 충분한 냉장효과를 달성하지 못하고 있다. 이러한 문제점은 냉장실 내부의 냉기공급이 후방에서 전방을 향하는 일방향으로 공급되고 있다는 점에 기인하고 있다.Therefore, since the cold air is not sufficiently supplied to the door side, which is the position most separated from the source of cold air, the food placed adjacent to the cold air discharge hole 10a is supercooled, and the food located on the door side does not achieve a sufficient refrigeration effect. have. This problem is due to the fact that the cold air supply inside the refrigerating chamber is supplied in one direction from the rear to the front.

또한 도어바스켓(14a)이 설치되어 있는 도어부근에는, 도어의 빈번한 개폐에 따른 외부 공기의 유입으로 인하여 냉장실의 내측에 비하여 현저하게 높은 온도를 유지하는 경향이 많다. 따라서 냉장고 도어의 바스켓(14a)에 보관하는 식품은 특히 신선도 유지가 어렵게 되는 단점이 있는 것이다.Further, near the door in which the door basket 14a is installed, there is a tendency to maintain a significantly higher temperature than the inside of the refrigerating chamber due to the inflow of external air due to frequent opening and closing of the door. Therefore, food stored in the basket 14a of the refrigerator door has a disadvantage in that it is particularly difficult to maintain freshness.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 냉장실 전체적으로 균일한 냉장효과를 달성할 수 있는 냉기공급구조를 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, and an object of the present invention is to provide a cold air supply structure that can achieve a uniform refrigeration effect as a whole.

본 발명의 다른 목적은 외부의 공기가 쉽게 유입되는 냉장고의 도어측의 냉각을 효과적으로 달성할 수 있는 냉기공급구조를 제공하는 것이다.Another object of the present invention is to provide a cold air supply structure that can effectively achieve the cooling of the door side of the refrigerator into which outside air is easily introduced.

Therefore, the refrigerating chamber duct 22 substantially used in the present specification means a conventional refrigerating chamber duct for supplying cold air to the refrigerating chamber 40, and is limited to one installed in the horizontal direction in the middle of the rear surface of the refrigerating chamber as shown. It is not intended to be used as a meaning including, for example, being installed at one side (rear or side) of the refrigerating compartment to supply cold air to the refrigerating compartment. That is, the present invention is to provide a technical gist to supply the cold air to the door duct 32 while passing through the lower surface of the refrigerating chamber, that is, the lower part of the vegetable box in the refrigerating chamber duct for supplying cold air to the refrigerating chamber.

이상과 같이 구성되는 본 발명에 의하던 다음과 같은 잇점이 기대된다.The following advantages by the present invention configured as described above are expected.

먼저, 본 발명에 의하면, 냉장실로의 냉기의 공급이 냉장고 후방 및 전방에서 동시에 이루어지기 때문에 냉장실 전체가 균일한 냉장효과를 얻을 수 있는 장점이 있다.First, according to the present invention, since the supply of cold air to the refrigerating compartment is simultaneously performed at the rear and front of the refrigerator, there is an advantage that the entire refrigerating compartment can obtain a uniform refrigeration effect.

그리고 냉장실의 도어측에서 후방을 향하여 냉기를 공급하는 구조를 가지는 것에 의하여, 냉장실의 전방 부분에 대한 냉장효과가 특히 우수하다. 이러한 점에 의하여 도어의 개폐시 외부 공기와 쉽게 접촉하는 냉장고의 전방 부분에 대한 냉기의 공급이 충분하여 잦은 도어의 개폐에도 불구하고 냉장실의 전방부분에 보관하는 식품을 항상 신선하게 유지하는 것이 가능해진다. 특히 도어덕트의 냉기토출공을 통하여 공급되는 냉기가 도어내측의 도어바스켓에 보관중인 식품을 경유할 수 있도록 위치를 조정하여 두면, 도어바스켓에 보관중인 식품에 직접 냉기를 공급하는 것이 가능하게된다. 이러한 점에 의하여 도어의 개폐시 가장 외기의 더운 공기와 접하는 도어바스켓 부분의 냉각효과를 충분하게 달성하는 것이 가능해 진다.And by having a structure which supplies cold air toward the back from the door side of a refrigerator compartment, the refrigeration effect with respect to the front part of a refrigerator compartment is especially excellent. Due to this, the supply of cold air to the front part of the refrigerator which is easily in contact with the outside air during opening and closing of the door is sufficient, so that food stored in the front part of the refrigerator compartment can be kept fresh at all times despite frequent opening and closing of the door. . In particular, if the position is adjusted so that the cold air supplied through the cold air discharge hole of the door duct can pass through the food stored in the door basket inside the door, it is possible to directly supply the cold air to the food stored in the door basket. This makes it possible to sufficiently achieve the cooling effect of the door basket portion in contact with the hot air of the outside air when the door is opened and closed.

또한 도어의 개폐로 인하여 냉장실 전방 부분의 온도가 쉽게 올라가나, 이러한 전방부분으로 도어덕트에서 냉기가 집중적으로 공급되기 때문에, 신속하게 원하는 온도로 낮추는 것이 가능하게 되는 효과가 기대된다.In addition, the temperature of the front portion of the refrigerating compartment easily rises due to the opening and closing of the door, but since cold air is intensively supplied from the door duct to the front portion, it is expected that the temperature can be quickly lowered to a desired temperature.
