Description

냉장고의 도어냉각장치{DOOR COOLING APPARATUS FOR REFRIGERATOR WITH DOUBLE ACTION DOOR}DOOR COOLING APPARATUS FOR REFRIGERATOR WITH DOUBLE ACTION DOOR}

본 발명은, 냉장고의 도어냉각장치에 관한 것으로서, 보다 상세하게는, 도어가 본체의 좌측 및 우측방향중 적어도 어느 일 방향으로 개방가능하게 설치될 경우에도 본체로부터의 냉기가 도어에 원활하게 공급될 수 있도록 유로절환이 가능한 냉장고의 도어냉각장치에 관한 것이다.The present invention relates to a door cooling apparatus of a refrigerator, and more particularly, even when the door is installed to be openable in at least one of left and right directions of the main body, cool air from the main body can be smoothly supplied to the door. It relates to a door cooling device of the refrigerator capable of switching the flow path.

도 1은 종래의 냉장고의 도어냉각장치의 구조를 개략적으로 도시한 도면이고, 도 2는 도 1의 냉장고의 도어의 닫힌 상태에서의 냉기유동방향에 따른 평단면도이다. 이들 도면에 도시된 바와 같이, 냉장고는 상하방향을 따라 냉동실 및 냉장실(113)이 각각 형성되어 있는 본체(110)와, 냉동실 및 냉장실(113)의 전면개구를 각각 회동개폐하도록 본체(110)의 일측에 힌지결합되는 냉동실도어(115) 및 냉장실도어(117)를 가진다.1 is a view schematically illustrating a structure of a door cooling apparatus of a conventional refrigerator, and FIG. 2 is a cross-sectional plan view of a refrigerator air flow direction in a closed state of a door of the refrigerator of FIG. 1. As shown in these drawings, the refrigerator includes a main body 110 in which a freezer compartment and a refrigerating compartment 113 are formed in the up and down directions, respectively, and the front openings of the freezer compartment and the refrigerating compartment 113 are rotated. It has a freezing chamber door 115 and the refrigerating chamber door 117 hinged to one side.

냉장실(113)의 내부에는 상하방향을 따라 선반(119)이 배치되어 있으며, 본체(110)의 전후방향을 따라 냉장실(113)의 후방영역에는 냉기를 토출할 수 있도록 냉장실냉기덕트(121)가 상하방향을 따라 배치되어 있다. 냉장실(113)의 후방벽 및 우측벽의 내부에는 냉장실도어(117)에 냉기를 공급할 수 있도록 측벽냉기덕트(123)가 매입형성되어 있으며, 전면개구영역에는 후술할 도어냉기덕트와 상호 연통되게 접속될 수 있도록 접속단부(124)가 형성되어 있다.The shelf 119 is disposed in the refrigerating chamber 113 in the up and down direction, and the refrigerating chamber cold air duct 121 is disposed in the rear region of the refrigerating chamber 113 along the front and rear directions of the main body 110 to discharge the cool air. It is arrange | positioned along the up-down direction. In the rear wall and the right side wall of the refrigerating chamber 113, a side wall cold air duct 123 is buried to supply cold air to the refrigerating chamber door 117, and the front opening area is connected to communicate with the door cold air duct to be described later. The connecting end 124 is formed to be.

한편, 냉장실도어(117)의 냉장실측 판면에는 상하방향을 따라 복수의 도어포켓(118)이 상하방향을 따라 이격배치되어 있으며, 중앙영역에는 측벽냉기덕트(123)와 상호 연통가능하도록 형성되어 하측에 배치된 도어포켓(118)내에 저장된 주류 또는 음료 등의 병류식품에 냉기를 공급하는 도어냉기덕트(125)가 형성되어 있다. 도어냉기덕트(125)에는 길이방향을 따라 상호 이격배치되어 냉기가 토출되는 복수의 냉기토출구(126)가 형성되어 있으며, 길이방향을 따라 힌지결합부측영역에는 측벽냉기덕트(123)로부터의 냉기가 유입될 수 있게 측벽냉기덕트(123)의 접속단부(124)에 상호 연통되게 접속되는 접속부(128)가 형성되어 있다.On the other hand, a plurality of door pockets 118 are spaced apart along the up and down direction in the refrigerating chamber side plate surface of the refrigerating chamber door 117, the central region is formed so as to communicate with the side wall cold air duct 123, the lower side The door cold air duct 125 is formed to supply cold air to the bottled food such as alcoholic beverage or beverage stored in the door pocket 118 disposed in the door pocket 118. The door cold air duct 125 is formed with a plurality of cold air discharge ports 126 spaced apart from each other along the longitudinal direction to discharge cold air, and cold air from the side wall cold air duct 123 is formed in the hinge coupling part side region along the longitudinal direction. The connection part 128 which is connected in mutual communication with the connection end part 124 of the side wall cold air duct 123 is formed so that it may flow in.

그런데, 이러한 종래의 냉장고의 도어냉각장치에 있어서는, 냉장실도어(117)에 냉기를 공급하기 위한 측벽냉기덕트(123)는 냉장실(113)의 후방벽 및 우측벽속에 매입되어 본체(110)의 형성시 일체로 형성되도록 되어 있어, 제작후에는 냉기의 유로변경이 불가능하기 때문에 본체(110)의 좌측으로 냉장실도어(117)가 개방되는 소위 “왼손잡이형”냉장고 및 좌우방향을 따라 선택적으로 개방이 가능한 소위 “양측 개방형”도어를 구비한 냉장고의 형태에 있어서는, 냉장실도어(117)가 측벽냉기덕트(123)와 도어냉기덕트(125)의 접속영역의 대향측 연부를 중심으로 회동할 경우, 측벽냉기덕트(117)와 도어냉기덕트(125)의 접속부가 상호 정확하게 일치되기 어려워 냉기의 누설이 발생되는 등 본체(110)으로부터의 냉기가 냉장실도어(117)로 원활하게 공급되지 못하게 되는 문제점이 있다.By the way, in the conventional door cooling apparatus of the refrigerator, the side wall cooling air duct 123 for supplying cold air to the refrigerating chamber door 117 is embedded in the rear wall and the right wall of the refrigerating chamber 113 to form the main body 110. Since it is impossible to change the flow path of cold air after manufacture, it is possible to selectively open along the left and right direction and the so-called "left-handed type" refrigerator in which the refrigerating chamber door 117 is opened to the left side of the main body 110. In the form of a refrigerator having a so-called "both sides open" door, when the refrigerating chamber door 117 rotates about the opposite edge of the connection area between the side wall cold air duct 123 and the door cold air duct 125, the side wall cold air It is difficult for the connecting portion of the duct 117 and the door cold air duct 125 to coincide with each other precisely so that cold air from the main body 110 cannot be smoothly supplied to the refrigerating chamber door 117. Has a problem.

따라서, 본 발명의 목적은, 도어가 본체의 좌측 및 우측방향중 적어도 어느 일 방향으로 개방가능하게 설치될 경우에도 본체로부터의 냉기가 도어에 원활하게공급될 수 있도록 유로절환이 가능한 냉장고의 도어냉각장치를 제공하는 것이다.Therefore, an object of the present invention, even if the door is installed to be open to at least one of the left and right direction of the main body door cooling of the refrigerator capable of switching the flow path so that the cool air from the main body can be smoothly supplied to the door To provide a device.
