Abstract

A refrigerator is provided to increase the effective capacity of the freezer and the cold room by appropriately rearranging the location of evaporators. The refrigerator is composed of a freezer(110) storing and freezing foods, a cold room(120) keeping foods cold, and a partition(130) separating the freezer and the cold room. An evaporator(440) for the freezer and an evaporator(460) for the cold room are installed in the partition. The effective capacity is increased by controlling the controlling the location of evaporators.

본 발명은 냉장고의 증발기 배치구조에 관한 것이다.The present invention relates to an evaporator arrangement of the refrigerator.

일반적으로 냉장고는 압축기, 응축기, 팽창변, 증발기로 이루어진 냉동사이클을 구비하고 증발기에서 발생되는 냉기를 냉동실 또는 냉장실의 고내로 공급하여 식품을 신선하게 저장하는 것이다.In general, a refrigerator includes a refrigeration cycle consisting of a compressor, a condenser, an expansion valve, and an evaporator, and supplies cold air generated in the evaporator into a freezer compartment or a refrigerator compartment to store food freshly.

최근 들어 냉장고가 격벽을 사이에 두고 좌우로 나뉘어 한쪽은 냉동실로, 다른 한쪽은 냉장실로 구분되는 양문형 등으로 대형화되면서 냉동실과 냉장실에 각각 증발기가 따로 배치되는 기술이 알려지고 있다. 복수의 증발기가 적용되는 기술에서는 양쪽 증발기가 한 개의 냉동사이클에서 서로 직렬 연결되도록 할 수도 있고 전혀 다른 복수의 냉동사이클에 설치되도록 할 수도 있고 압축기를 공유하면서 복수의 냉동사이클에 설치되도록 할 수도 있다.Recently, a refrigerator is divided into left and right sides with a partition wall and is enlarged into a double door type, such as a freezer compartment and a freezer compartment. In a technology in which a plurality of evaporators are applied, both evaporators may be connected in series in one refrigeration cycle, may be installed in a plurality of completely different refrigeration cycles, or may be installed in a plurality of refrigeration cycles while sharing a compressor.

그러나, 상기와 같은 종래 복수의 증발기가 구비되는 냉장고에서는, 양쪽 증 발기가 통상 냉동실의 후벽면과 냉동실의 후벽면에 각각 설치됨에 따라 냉동실과 냉장실의 전체 유효내용적이 좁아질 뿐만 아니라 특히 깊이가 얕아져 식품을 수납하는데 한계가 있었다.However, in the refrigerator equipped with a plurality of conventional evaporators as described above, since both evaporators are usually installed on the rear wall surface of the freezer compartment and the rear wall surface of the freezer compartment, the overall effective contents of the freezer compartment and the refrigerating compartment are not only narrow, but also particularly shallow. There was a limit to storing food.

본 발명은 상기와 같은 종래 냉장고가 가지는 문제점을 해결한 것으로, 상기 증발기의 위치를 적절하게 재배치하여 냉동실과 냉장실의 유효내용적을 넓힐 수 있는 냉장고를 제공하려는데 본 발명의 목적이 있다.The present invention solves the problems of the conventional refrigerator as described above, it is an object of the present invention to provide a refrigerator that can reposition the location of the evaporator to properly expand the effective contents of the freezer compartment and the refrigerating compartment.

본 발명의 목적을 달성하기 위하여, 식품을 냉동보관하는 냉동실과 냉장보관하는 냉장실이 격벽에 의해 분리되는 냉장고에 있어서, 상기 격벽에 냉동실용 증발기와 냉장실용 증발기가 설치되는 냉장고가 제공된다.In order to achieve the object of the present invention, there is provided a refrigerator in which a freezer compartment for freezing food and a refrigerating compartment for storing food are separated by a partition wall, wherein a freezer compartment evaporator and a refrigerator compartment evaporator are provided on the partition wall.

Freshly freezes food or beverages, which are directly supplied to the door baskets 220 and 320 of the freezing chamber door 200 and the refrigerating chamber door 300 through 311a, and stored in the door baskets 220 and 320. Or refrigerated.

여기서, 상기 냉동실(110)과 냉장실(120)은 가능한 한 유효내용적이 넓어야 많은 식품을 수납할 수 있을 뿐만 아니라 냉기의 흐름이 원활하게 되어 식품을 더욱 신선하게 보관할 수 있다. 하지만, 냉동실(110)과 냉장실(120)의 후벽면쪽에 각각 제1 증발기와 제2 증발기가 설치되는 경우 냉동실과 냉장실의 유효내용적이 그만큼 줄어들게 된다. 이를 감안하여 본 발명에서와 같이 상기 제1 증발기(440)와 제2 증발기(460)를 냉동실(110)과 냉장실(120)을 구분하는 격벽(130)의 안쪽에 설치하는 경우에는 상기 냉동실(110)과 냉장실(120)의 후벽면쪽에 상기 제1 증발기(440)와 제2 증발기(460)를 설치하기 위한 별도의 공간을 구비하지 않게 되므로 그만큼 냉동실(110)과 냉장실(120)의 깊이를 깊게 할 수 있고 이를 통해 상기 냉동실(110)과 냉장실(120)의 유효내용적을 크게 넓힐 수 있다. 또, 상기 냉동실도어(200)와 냉장실도어(300)에 냉기유로(211)9311)가 형성되어 상기 제1 증발기(440)와 제2 증발기(460)에서 만들어진 냉기를 각 도어(200)(300)의 도어바스켓(220)(320)에 직접 공급하는 경우에는 상기 고내(110)(120)와 도어브스켓(220)(320) 사이의 온도편차를 없애 상기 도어바스켓(220)(320)에 수납되는 식품이나 음료를 더욱 신선하게 보관할 수 있다.Here, the freezing chamber 110 and the refrigerating chamber 120 may not only accommodate a large amount of food when the effective content is as wide as possible, but also keep the food fresher as the flow of cold air is smooth. However, when the first evaporator and the second evaporator are respectively installed on the rear wall surfaces of the freezing compartment 110 and the refrigerating compartment 120, the effective contents of the freezing compartment and the refrigerating compartment are reduced by that amount. In consideration of this, when the first evaporator 440 and the second evaporator 460 are installed inside the partition 130 separating the freezer compartment 110 and the refrigerating compartment 120, as in the present invention, the freezer compartment 110 is provided. ) And the rear wall of the refrigerating chamber 120 does not have a separate space for installing the first evaporator 440 and the second evaporator 460, so that the depth of the freezing chamber 110 and the refrigerating chamber 120 is deepened. Through this, the effective contents of the freezing compartment 110 and the refrigerating compartment 120 may be greatly widened. In addition, cold air passages 211 and 9311 are formed in the freezing chamber door 200 and the refrigerating chamber door 300 so that the cold air generated in the first evaporator 440 and the second evaporator 460 is formed in each door 200 or 300.
