Abstract

본 고안은 냉장고용 사절판에 관한 것으로서, 더 자세하게는 냉장실도어의 개폐시에 발생하는 공기압에 의한 냉동실도어의 열림을 방지하기 위하여 고안한 냉장고용 사절판의 온기흡입장치에 관한 것이다.The present invention relates to a trimming plate for a refrigerator, and more particularly, to a warmth suction device of a trimming plate for a refrigerator designed to prevent the freezing chamber door from being opened by air pressure generated during opening and closing of the refrigerator compartment door.

일반적으로 냉장실도어의 개폐시에는 외부와 냉장고내의 압력차에 의하여 상당한 세기의 공기압이 순간적으로 발생하게 되는데, 종래의 냉장고는 사절판하면에 형성된 온기흡입구에 상술한 공기압의 세기를 적절히 감소시킬 수 있는 수단이 형성되어 있지 않아서, 상술한 공기압이 사절판에 형성된 냉기순환로에 그대로 유입되게 된다.In general, during opening and closing of the refrigerating chamber door, a considerable intensity of air pressure is generated instantaneously due to a pressure difference between the outside and the refrigerator. In the conventional refrigerator, the above-described strength of the air pressure can be appropriately reduced at the warm air intake formed on the bottom of the trimmer. Since no means is formed, the aforementioned air pressure is introduced into the cold air circulation path formed in the trimming plate as it is.

그리하여, 사절판에 형성된 냉동실과 냉장실의 냉기순환로는 상호연결되어 있으므로, 상술한 공기압은 냉기순환로를 따라 냉동실로 유입되어, 그 압력에 의하여 냉동실도어가 열리게 되고, 이에 따라 냉장고의 냉기손실과 전력소모가 발생하는 문제점이 있었다.Thus, since the cold air circulation paths of the freezer compartment and the refrigerating compartment formed in the trimming plate are interconnected, the above-mentioned air pressure flows into the freezer compartment along the cold air circulation path, and the freezer compartment door is opened by the pressure, thereby reducing the cold air loss and power consumption of the refrigerator. There was a problem that occurred.

따라서, 본 고안은 이러한 종래의 문제점을 감안하여 안출한 것으로서, 상술한 냉장실도어의 개폐시에 발생하는 공기압이 온기흡입구를 통하여 냉기순환로로 일시에 유입됨을 방지하여, 냉동실도어가 열리지 않도록 하는 온기흡입구커버를 제공하는 것을 목적으로 한다.Therefore, the present invention has been devised in view of the above-mentioned conventional problems, and prevents the air pressure generated during the opening and closing of the refrigerating chamber door to be temporarily introduced into the cold air circulation path through the warm air suction opening, thereby preventing the freezing chamber door from opening. It is an object to provide a cover.

이와 같은 목적을 달성하기 위하여 본 고안은, 냉장실(20)에서 순환된 냉기를 흡입하여 냉각기실로 공급하는 냉기순환로(130)가 설치된 냉장고에 있어서, 상기 냉기순환로(130)의 입구측에 삽입고정되도록 하면 일측부분이 사각형상으로 함몰형성됨과 아울러 그 바닥면에 일정간격을 두고 다수의 냉기유입공(131c)과 내측벽에 다수의 결합공(131b)이 형성된 온기흡입구(131)를 갖는 사절부(30)와, 상기 온기흡입구(131)에 형성된 냉기유입공(131c)과 엇갈리도록 다수의 냉기유입공(132a)이 일정간격을 두고 형성됨과 아울러 상기 온기흡입구(131)의 결합공(131b)에 삽입고정될 수 있도록 결합부(132b)가 형성된 온기흡입구커버(132)로 구성된다.In order to achieve the above object, the present invention, in the refrigerator equipped with a cold air circulation path 130 to suck the cold air circulated in the refrigerating compartment 20 to the cooler chamber, to be inserted and fixed to the inlet side of the cold air circulation path (130).

본 고안은 냉장고용 사절판에 관한 것으로서, 더 자세하게는 냉장실도어의 개폐시에 발생하는 공기압에 의한 냉동실도어의 열림을 방지할 수 있도록한 냉장고용 사절판의 온기흡입장치에 관한 것이다.The present invention relates to a trimming plate for a refrigerator, and more particularly, to a warmth suction device of a trimming plate for a refrigerator to prevent opening of the freezing chamber door due to air pressure generated during opening and closing of the refrigerator compartment door.

일반적인 냉장고에서는 첨부도면 제1도에 도시한 것과 같이, 냉장고(1)의 상부와 하부에는 각각 냉동실(10)과 냉장실(20)이 위치하며, 냉동실(10)의 후방에는 주냉기덕트(100)를 형성하여 그 내부에 냉각기(110) 및 냉기순환팬(120)을 설치하고, 냉장실(20)의 소정위치에는 온기흡입구(131)와 냉기토출구(141)를 각각 형성하며, 상술한 온기흡입구(131)와 냉기토출구(141)는 냉장고(1)내에 형성된 냉기순환로(130)와 냉기덕트(140)를 통하여 주냉기덕트(100)에 연결되므로써, 냉장고(1)내에 냉기가 순환하게 된다.In a typical refrigerator, as illustrated in FIG. 1 of the accompanying drawings, a freezing compartment 10 and a refrigerating compartment 20 are positioned at upper and lower portions of the refrigerator 1, respectively, and a main cold air duct 100 is located at the rear of the freezing compartment 10. And a cooler 110 and a cold air circulation fan 120 therein, and a warm air inlet 131 and a cold air outlet 141 are formed at predetermined positions of the refrigerating chamber 20, respectively. 131 and the cold air discharge port 141 are connected to the main cold air duct 100 through the cold air circulation path 130 and the cold air duct 140 formed in the refrigerator 1, thereby circulating cold air in the refrigerator 1.

한편, 냉장실도어(21)의 개폐시에는 외부와 냉장고(1)내의 압력차에 의하여 상당한 세기의 공기압이 순간적으로 발생하게 되는데, 종래의 냉장고(1)는 사절판(30) 하면에 형성된 온기흡입구(131)에 상술한 공기압의 세기를 적절히 감소시켜 줄 수 있는 수단이 형성되어 있지 않아서, 상술한 공기압이 사절판(30)에 형성된 냉기순환로(130)에 그대로 유입되게 된다.On the other hand, when opening and closing the refrigerating chamber door 21, the air pressure of a considerable intensity is instantaneously generated by the pressure difference between the outside and the refrigerator 1, the conventional refrigerator 1 is a warm air intake formed on the lower surface of the trimming plate (30) Means for appropriately reducing the strength of the above-described air pressure are not formed at 131, so that the above-described air pressure flows directly into the cold air circulation path 130 formed in the trimming plate 30.

그리하여, 사절판(30)에 형성된 냉동실(10)과 냉장실(20)의 냉기순환로(130)는 상호연결되어 있으므로, 상술한 공기압은 냉기순환로(130)를 따라 냉동실(10)로 유입되어, 그 압력에 의하여 냉동실도어(11)가 열리게 되고, 이에 따라 냉장고(1)의 냉기손실과 전력소모가 발생하는 문제점이 있었다.Thus, since the freezing chamber 10 and the cold air circulation path 130 of the refrigerating chamber 20 formed in the trimming plate 30 are interconnected, the above-described air pressure flows into the freezing chamber 10 along the cold air circulation path 130, and The freezing chamber door 11 is opened by the pressure, and thus there is a problem in that cold air loss and power consumption of the refrigerator 1 occur.

따라서, 본 고안은 이러한 종래의 문제점을 감안하여 안출한 것으로서, 상술한 냉장실도어의 개폐시에 발생하는 공기압이 온기흡입구를 통하여 냉기순환로로 일시에 유입됨을 방지하여 냉동실도어가 열리지 않도록 하는 냉장고용 사절판의 온기흡입장치를 제공하는 것을 목적으로 한다.Therefore, the present invention has been made in view of such a conventional problem, the refrigerator for preventing the air pressure generated during opening and closing of the refrigerating chamber door described above to temporarily enter the cold air circulation path through the warm air suction port so that the freezer compartment door does not open. It is an object of the present invention to provide a warm-up suction device for printing.

이와 같은 목적을 달성하기 위하여 본 고안은 냉장실(20)에서 순환된 냉기를 흡입하여 냉각기실로 공급하는 냉기순환로(130)가 설치된 냉장고에 있어서, 상기 냉기순환로(130)의 입구측에 삽입고정되도록 하면 일측부분이 사각형상으로 함몰형성됨과 아울러 그 바닥면에 일정간격을 두고 다수의 냉기유입공(131c)과 내측벽에 다수의 결합공(131b)이 형성된 온기흡입구(131)를 갖는 사절부(30)와, 상기 온기흡입구(131)에 형성된 냉기유입공(131c)과 엇갈리도록 다수의 냉기유입공(132a)이 일정간격을 두고 형성됨과 아울러 상기 온기흡입구(131)의 결합공(131b)에 삽입고정될 수 있도록 결합부(132b)가 형성된 온기흡입구커버(132)로 구성됨을 특징으로 한다.In order to achieve the above object, the present invention is a refrigerator having a cold air circulation path 130 that sucks cold air circulated in the refrigerating chamber 20 and supplies it to a cooler room, and is inserted and fixed at an inlet side of the cold air circulation path 130. One side portion is formed in a rectangular shape, and the cutout portion 30 having a warm air suction hole 131 formed with a plurality of cold air inlet holes (131c) and a plurality of coupling holes (131b) in the inner wall at regular intervals. ) And a plurality of cold air inlet holes 132a are formed at a predetermined interval so as to intersect with the cold air inlet holes 131c formed in the warm air intake hole 131 and are inserted into the coupling holes 131b of the warm air intake hole 131.

제2도 및 제3도를 참조하면, 온기흡입구(131)는 냉장실(20)에서 순환된 냉기를 흡입하여 냉각기실로 공급하는 냉기순환로(130)의 입구측에 삽입됨과 아울러, 사절판(30)의 하면이 내측으로 함몰된 사각 형상으로 형성되고, 함몰되어진 온기흡입구내측면(131a)은 등간격을 두고 형성된 다수개의 냉기유입공(131c)을 갖도록 하며, 온기흡입구내측벽부(131b)에는 후술할 온기흡입구커버(132)를 끼우기 위한 결합공(131d)이 형성된다.Referring to FIGS. 2 and 3, the warm air inlet 131 is inserted into the inlet side of the cold air circulation path 130 that sucks the cold air circulated in the refrigerating compartment 20 and supplies it to the cooler chamber, and the trimming plate 30. The lower surface of the inlet is formed in a rectangular shape recessed inward, and the recessed warmth inlet side surface 131a has a plurality of cold air inlet holes 131c formed at equal intervals, and the warmth inlet inner wall portion 131b will be described later. A coupling hole 131d for fitting the warmth air intake cover 132 is formed.

그리고, 사각 형상으로 함몰되어진 부분에 삽입고정되는 온기흡입구커버(132)에는 상기 온기흡입구(131)의 냉기유입공(131c)과 엇갈리도록 등간격으로 다수개의 냉기유입공(132a)이 형성되, 상기 온기흡입구커버(132)의 양측부에는 상술한 온기흡입구내측벽부(131b)에 형성한 결합공(131b)에 온기흡입구커버(132)를 끼울 수 있도록 결합부(132b)가 형성된다.In addition, a plurality of cold air inlet holes 132a are formed at equal intervals so as to alternate with cold air inlet holes 131c of the warm air intake hole 131 to the warm air inlet cover 132 inserted and fixed to the recessed portion in a square shape. Coupling portions 132b are formed at both sides of the warm air intake cover 132 so as to fit the warm air intake cover 132 into the coupling hole 131b formed in the above-described warm air intake inner wall 131b.

따라서, 온기흡입구커버(132)는 온기흡입구(131)와 적정간격으로 사절판(30) 하면과 수평이 되게 설치된다.Therefore, the warm air intake cover 132 is installed to be horizontal to the bottom surface of the trimming plate 30 at an appropriate interval with the warm air intake 131.

이와 같이 구성된 본 고안의 작용 및 효과를 상세히 설명한다.The operation and effects of the present invention configured as described above will be described in detail.

제2도와 제3도에 도시한 것과 같이, 온기흡입구(131)의 냉기유입공(131c)과 온기흡입구커버(132)의 냉기유입공(132a)은 상호 엇갈리도록 형성되어 있으므로, 냉장실도어(21)의 개폐시에 발생하는 공기압은 온기흡입구커버(132)의 냉기유입공(132a)을 통과한 후에는 온기흡입구내측면(131a)에 부딪치게 되어, 일단은 온기흡입구커버(132)와 온기흡입구(131) 사이에서 머무르게 된다.As shown in FIG. 2 and FIG. 3, since the cold air inlet hole 131c of the warm air inlet 131 and the cold air inlet hole 132a of the warm air inlet cover 132 are formed to cross each other, the refrigerating chamber door 21 The air pressure generated at the time of opening and closing of the air) hits the warm air inlet opening side surface 131a after passing through the cold air inlet hole 132a of the warm air inlet cover 132, and once the warm air inlet cover 132 and the warm air inlet ( 131).

따라서, 상술한 공기압이 냉기순환로(130)로 일시에 유입되지 않게 되어, 냉기순환로(130)를 따라 냉동실(10)로 유입되는 공기압의 세기가 감소되므로, 냉장실도어(21)의 개폐시에 발생하는 공기압에 의한 냉동실도어(11)의 열림을 방지할 수 있다.Therefore, the above-described air pressure does not flow into the cold air circulation path 130 at a time, and thus the intensity of the air pressure flowing into the freezing chamber 10 along the cold air circulation path 130 is reduced, so that it occurs when the refrigerating chamber door 21 opens and closes. It is possible to prevent the freezing chamber door 11 from being opened due to air pressure.

상술한 구성에 의하면 본 고안에 의한 냉장고(1)용 사절판(30)의 냉기흡입구커버(132)는 냉장실도어(21)의 개폐시에 냉동실도어(11)가 열리는 것을 방지하여 냉기손실과 그에 따른 전력소모를 막을 수 있어 소비자의 제품에 대한 불만을 해소하게 된다.According to the above configuration, the cold air inlet cover 132 of the trimming plate 30 for the refrigerator 1 according to the present invention prevents the freezer door 11 from being opened when the refrigerating chamber door 21 is opened and closed, and thus It can prevent the power consumption according to the customer's dissatisfaction with the product.

또한, 본 고안에 따른 냉장고(1)는 온기흡입구커버(132)가 사절판(30)하면에 내설되므로서, 사절판(30)하면이 수평을 이루게 되어 온기흡입구커버(132)가 냉장실(20)내의 실용공간을 차지하지 않게 되고 미적인 면에서도 우수하게 되는 장점이 있다.In addition, in the refrigerator 1 according to the present invention, since the warmth inlet cover 132 is installed on the bottom of the trimming plate 30, the bottom of the trimming plate 30 is horizontal to form the warmth inlet cover 132 in the refrigerating chamber 20. It does not occupy any practical space in) and has the advantage of being superior in aesthetics.
