Abstract
Description
본 발명은 냉장고에 관한 것으로서, 보다 상세하게는 필요에 따라 도어 측에서의 냉기 배출을 선택적으로 제한함으로써 냉장실 도어에 수납된 음식물의 과냉각을 방지하고, 보다 효율적인 냉각작용을 수행할 수 있는 입체 냉각방식 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a three-dimensional cooling type refrigerator that can prevent overcooling of food stored in the refrigerating compartment door by selectively limiting the discharge of cold air from the door side as needed, and perform a more efficient cooling operation. It is about.
냉장고는 음식물 등을 냉동시키거나, 냉장보관하기 위해 사용되는 것으로서, 그 내부에 냉동실과 냉장실로 분리된 수납공간을 형성하는 케이스 및 상기 케이스의 일측에 장착되어 냉동실과 냉장실을 개폐하는 냉동실 및 냉장실 도어와, 압축기, 응축기 및 증발기 등과 같이 냉동사이클을 이루어 냉동실과 냉장실의 온도를 낮추기 위한 기기들을 포함하여 구성되어 있다.The refrigerator is used to freeze or refrigerate food and the like, and includes a case forming a storage space separated into a freezer compartment and a refrigerating compartment, and a freezer compartment and a refrigerator compartment door installed at one side of the case to open and close the freezer compartment and the refrigerating compartment. And, by forming a refrigeration cycle, such as a compressor, condenser and evaporator is configured to include a device for lowering the temperature of the freezer compartment and the refrigerating compartment.
그리고, 이와 같은 냉장고의 냉각방식은 케이스 내에 구성된 냉기유로의 형태에 따라 단일 냉각방식과 입체 냉각방식으로 구분되는데, 단일 냉각방식은 냉기덕트가 케이스의 후면에만 구성됨으로써 냉기가 일측에서 집중 토출되는 방식이며, 입체 냉각방식은 냉기덕트가 케이스의 삼면에 고루 배치될 뿐만 아니라, 냉장실 도어에도 배치되어 냉기유로가 입체적으로 냉장실의 냉각공간을 둘러쌈으로써 냉기의 토출이 여러 방향에서 이루어지는 방식이다.In addition, the cooling method of such a refrigerator is divided into a single cooling method and a three-dimensional cooling method according to the shape of the cold air flow path configured in the case. In the single cooling method, the cold air duct is formed only at the rear of the case, where the cold air is concentrated at one side. In the three-dimensional cooling method, the cold air duct is not only evenly disposed on three sides of the case, but is also disposed in the refrigerating chamber door so that the cold air flow passage surrounds the cooling space of the refrigerating compartment three-dimensionally, thereby discharging the cold air in various directions.
상기 입체 냉각방식에 의하면 냉기의 토출이 여러 방향에서 이루어짐으로써 냉각공간내의 온도가 고르게 유지되기 때문에 단일 냉각방식에 비해 고내에 저장된 식품이 비교적 고르게 냉각된다.According to the three-dimensional cooling method, since the temperature of the cooling space is maintained evenly by discharging the cold air in various directions, the food stored in the refrigerator is relatively evenly cooled compared to the single cooling method.
한편, 이러한 입체 냉각방식의 냉장고에서 냉장실 도어 측으로 구성된 냉기유로는 도 1에 나타난 것과 같이 케이스(10) 측면에 구성된 냉장실 덕트(12)와 연계되도록 냉장실 도어(20)에 구비된 도어덕트(22)로 이루어져 있는데, 상기 도어덕트(22)는 냉장실 도어(20)가 닫힌 상태에서 냉장실 덕트(12) 선단의 냉기연결구(12a)와 접하는 냉기유입구(22a)가 그 선단에 형성되며, 중간에 냉기의 토출을 위한 냉기배출구(22b)가 형성된 구조로 이루어져 있다. 여기서, 상기 도어덕트(22)는 대략 냉장실 도어(20)의 대략 상부에 위치되어 있으며, 냉기배출구(22b)는 냉기의 배출방향이 아래를 향하도록 형성되어 있다.On the other hand, in the three-dimensional cooling method of the refrigerator air passage configured as the refrigerator compartment door side as shown in Figure 1 door duct 22 provided in the refrigerator compartment door 20 to be associated with the refrigerator compartment duct 12 configured on the side of the case 10 The door duct 22 has a cold air inlet 22a contacting the cold air connector 12a at the tip of the refrigerator compartment duct 12 in a state in which the refrigerator compartment door 20 is closed, and the cold air inlet 22a is formed at the front end thereof. It consists of a structure in which the cold air discharge port 22b for discharge is formed. Here, the door duct 22 is located approximately at the top of the refrigerating compartment door 20, the cold air outlet 22b is formed so that the discharge direction of the cold air is directed downward.
이와 같은 입체 냉각방식의 냉장고에 의하면 냉장실 도어(20)가 닫힌 상태에서 도어덕트(22)의 냉기유입구(22a)가 냉장실 덕트의 냉기연결구(12a)와 밀착됨으로써 증발기(E)에서 송풍되는 냉기(도면상 화살표시)가 냉장실 덕트(12)로부터 도어덕트(22)에 까지 이송되며, 이와 같이 이송된 냉기가 냉기배출구(22b)를 통해 도어덕트(22)의 하방에 위치된 도어 바스켓(24) 측으로 집중 배출됨으로써 냉장실에 대한 입체냉각 효과와 함께 상기 도어 바스켓(24)에 수납된 식품을 빠르게 냉각시키는 효과를 얻게 된다.According to the three-dimensional cooling method of the refrigerator, the cold air inlet 22a of the door duct 22 is in close contact with the cold air connector 12a of the refrigerating chamber duct while the refrigerating compartment door 20 is closed. Arrow in the drawing) is conveyed from the refrigerating chamber duct 12 to the door duct 22, the cold air thus conveyed through the cold air outlet 22b, the door basket 24 located below the door duct 22 By intensively discharging to the side, a three-dimensional cooling effect on the refrigerating chamber is obtained, and an effect of rapidly cooling the food stored in the door basket 24 is obtained.
그러나, 상술한 바와 같은 종래기술에 의하면 도어덕트(22)를 통해 배출되는 냉기가 일측으로 편중되므로, 상기 도어덕트와 근접한 도어 바스켓에 수납된 식품이 과냉각될 뿐만 아니라, 도어 바스켓에 보관된 식품이 없어 냉기의 분산이 필요치 않은 경우에도 냉장고의 작동 시에는 도어덕트를 통해 항상 냉기가 배출되기 때문에 냉기의 적절한 배분을 통한 효율적인 냉각작용을 이룰 수 없다는 문제점이 있다.However, according to the prior art as described above, since the cold air discharged through the door duct 22 is biased to one side, not only the food stored in the door basket close to the door duct is supercooled, but also the food stored in the door basket. Since there is no need to disperse the cold air, there is a problem in that the cooling air is always discharged through the door duct during the operation of the refrigerator, so that efficient cooling can not be achieved through proper distribution of the cold air.
본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 냉장실 도어 측에서 고르게 냉기가 배출되도록 할 뿐만 아니라, 필요에 따라 냉기의 배출을 제한함으로써 냉장실 도어에 수납된 음식물의 과냉각을 방지하고, 보다 효율적인 냉각작용을 수행할 수 있는 입체 냉각방식 냉장고의 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, not only to ensure that the cold air is evenly discharged from the refrigerating compartment door side, but also to prevent the overcooling of food stored in the refrigerating compartment door by limiting the discharge of cold air, if necessary, more efficient An object of the present invention is to provide a three-dimensional cooling type refrigerator capable of performing a cooling operation.

이하, 본 발명의 실시예를 첨부된 도 2부터 도 4b까지 참조로 하여 상세하게 설명하며, 본 발명의 내용 중 종래구성과 동일한 부분에 대해서는 동일한 부호를 부여하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 4B, and the same reference numerals will be given to the same parts as in the prior art.
본 발명의 실시예에 따른 입체 냉각방식 냉장고는 냉장실을 구성하는 케이스 내에 배치되어 증발기로부터 송풍된 냉기의 유로를 형성하는 냉장실 덕트와, 상기 냉장실 덕트와 연결되어 냉장실 도어에서 냉기토출이 가능토록 하며, 필요에 따라 냉기의 토출을 제한할 수 있도록 하는 덕트수단을 포함하여 이루어진다.The three-dimensional cooling method refrigerator according to an embodiment of the present invention is disposed in a case constituting the refrigerating compartment, the refrigerator compartment duct to form a flow path of cold air blown from the evaporator, and connected to the refrigerating compartment duct to allow the discharge of cold air from the refrigerator compartment door, If necessary, it comprises a duct means for limiting the discharge of cold air.
상기 덕트수단은 도 2에 나타난 것과 같이 그 일측에 다수개의 냉기배출구(30a)가 형성되며, 냉장실 도어(20)가 닫힌 상태에서 상기 냉장실 덕트(12)와 연결되는 도어덕트(30)와, 상기 도어덕트(30)의 내부에 슬라이드 이동 가능하게 장착되어 그 위치에 따라 냉기배출구(30a)를 개방/폐쇄하는 한 쌍의 냉기 조절셔터(40)(40')로 이루어진다.As shown in FIG. 2, the duct means includes a plurality of cold air outlets 30a formed at one side thereof, the door duct 30 connected to the refrigerating chamber duct 12 in a closed state of the refrigerating compartment door 20, and the It is comprised of a pair of cold air control shutters 40 and 40 'which are mounted to be slidably movable in the door duct 30 and open / close the cold air outlet 30a according to its position.
상기 도어덕트(30)는 그 일측 선단에 냉장실 덕트(12)의 냉기연결구(12a)와 접속되는 냉기유입구(30b)가 구비되고, 상기 냉기배출구(30a)가 길이방향으로 일렬 배치되며, 그 중간에 한 쌍의 손잡이 돌출구(30c)가 형성된 구조로 이루어진다. 그리고, 상기 각 냉기 조절셔터(40)(40')는 동일한 구조로서 도 3에 나타난 것과 같이 다수개의 냉기통과홀(42a)이 형성된 슬라이드 플레이트(42)와, 상기 슬라이드 플레이트(42)의 일측에 구비되어 손잡이 돌출구(30c)를 통해 도어덕트(30)의 외부로 돌출되는 조절손잡이(44)로 구성된다.The door duct 30 has a cold air inlet 30b connected to the cold air connector 12a of the refrigerating chamber duct 12 at one end thereof, and the cold air outlet 30a is arranged in a line in the longitudinal direction, and the middle A pair of handle protrusions 30c are formed in the structure. Each of the cold air control shutters 40 and 40 'has the same structure as shown in FIG. 3 and includes a slide plate 42 having a plurality of cold air passage holes 42a formed thereon, It is provided with a control knob 44 is provided to protrude to the outside of the door duct 30 through the handle protrusion (30c).
상술한 바와 같이 구성된 본 실시예에 따른 입체 냉각방식 냉장고에 의하면 상기 냉기 조절셔터(40)(40')를 조작하여 냉장실 도어(20) 측에서의 냉기배출을 제한하거나, 냉기의 배출량을 조절할 수 있는데, 이에 대해 보다 자세히 설명하면 다음과 같다.According to the three-dimensional cooling type refrigerator according to the present embodiment configured as described above, by operating the cold air control shutters (40, 40 ') to limit the discharge of cold air in the refrigerating chamber door 20 side, it is possible to adjust the discharge of cold air, This will be described in more detail as follows.
우선, 도 4a에 나타난 것과 같이 냉기 조절셔터(40)의 슬라이드 플레이트(42)에 형성된 냉기통과홀(42a)이 도어덕트(30)의 냉기배출구(30a)와 일치된 상태에서는 상기 냉기배출구(30a)가 개방되므로 도어덕트(30)로 유입된 냉기가 상기 냉기배출구(30a)를 통해 배출됨으로써 평상시와 같은 입체 냉각작용을 이루게 된다.First, as shown in FIG. 4A, in the state where the cold air passage 42a formed in the slide plate 42 of the cold air control shutter 40 coincides with the cold air outlet 30a of the door duct 30, the cold air outlet 30a is provided. Since) is opened, the cold air introduced into the door duct 30 is discharged through the cold air discharge port 30a, thereby achieving a three-dimensional cooling function as usual.
그리고, 도 4b에 나타난 것과 같이 슬라이드 플레이트(42)를 타측으로 움직여 냉기통과홀(42a)이 냉기배출구(30a)와 엇갈리도록 하면 상기 냉기배출구(30a)가 폐쇄된 상태가 되므로 도어덕트(30)를 통한 냉기의 배출이 차단된다. 이와 같이 도어덕트(30)를 통한 냉기의 배출이 차단된 상태에서는 냉각작용에 필요한 냉기가 냉장실 덕트(12)를 통해 냉장실 안쪽으로 집중되므로 식품이 냉장실 안쪽에만 보관된 경우에 효율적인 냉각작용을 이루게 된다.And, as shown in Figure 4b by moving the slide plate 42 to the other side so that the cold air passage 42a and the cold air outlet (30a) is the cold air outlet (30a) is closed because the door duct 30 The discharge of cold air through is blocked. As such, in the state in which the discharge of the cold air through the door duct 30 is blocked, since the cold air required for the cooling action is concentrated inside the refrigerating compartment through the refrigerating compartment duct 12, efficient cooling is achieved when food is stored only in the refrigerating compartment. .
이어서, 조절손잡이(44)를 통해 슬라이드 플레이트(42)의 위치를 적절히 조절함으로써 냉기통과홀(42a)이 냉기배출구(30a)와 부분적으로 일치되도록 하면, 상기 냉기배출구(30a)가 부분적으로만 개방되므로, 냉기의 배출량을 변화시킬 수 있는데, 이에 따르면 도어바스켓(24)에 보관된 식품의 양이 적은 경우에 냉기의 배출량을 적절히 저감시킴으로써 보다 유용한 냉각작용을 이룰 수 있다.Subsequently, when the position of the slide plate 42 is properly adjusted through the adjusting knob 44 so that the cold air passage hole 42a partially coincides with the cold air outlet 30a, the cold air outlet 30a is only partially opened. Therefore, it is possible to change the discharge of cold air, whereby when the amount of food stored in the door basket 24 is reduced by appropriately reducing the discharge of cold air can achieve a more useful cooling action.
뿐만 아니라, 경우에 따라 일측 냉기 조절셔터(40)를 조작하여 일부 냉기배출구(30a)를 폐쇄하고, 타측 냉기 조절셔터(40')를 조작하여 나머지 냉기배출구(30a)를 개방함으로써 상기 도어덕트(30)를 통해 배출되는 냉기가 일측으로 집중되도록 할 수 있다.(도 2 참조)In addition, in some cases, one side of the cold air outlet 30a is operated by operating one side cold air control shutter 40 and the other side is controlled by opening the remaining air air outlet 30a by operating the cold air outlet 40a. The cold air discharged through 30 may be concentrated to one side (see FIG. 2).
본 발명에 따른 입체 냉각방식의 냉장고에 의하면 도어덕트를 통한 냉기의 배출을 선택적으로 제한함과 동시에 배출되는 냉기의 양을 조절함으로써 냉장실 도어에 수납된 음식물의 과냉각을 방지할 수 있는 등, 보다 효율적인 냉각작용이 가능해진다는 이점이 있다.According to the refrigerator of the three-dimensional cooling method according to the present invention, by selectively limiting the discharge of cold air through the door duct and controlling the amount of cold air discharged, it is possible to prevent overcooling of food stored in the refrigerator compartment door. There is an advantage that the cooling action is possible.
