Description

하부에 냉동실을 구비한 냉장고{refrigerator having freezer in lower part}Refrigerator with freezer at the bottom {refrigerator having freezer in lower part}

본 발명은 하부에 냉동실을 구비한 냉장고에 관한 것으로써, 보다 상세하게는 상부측에 위치한 냉장실에 얼음 공급을 위한 보조냉동실을 구비한 냉장고에 관한 것이다.The present invention relates to a refrigerator having a freezer compartment at the bottom, and more particularly, to a refrigerator having an auxiliary freezer compartment for supplying ice to a refrigerator compartment located at an upper side.

일반적으로, 냉장고는 냉매(작동유체)가 압축 - 응축 - 팽창 - 증발하는 냉동사이클을 반복함에 따라 고내를 저온화시켜 음식물을 일정기간 동안 신선하게 유지시켜 주는 장치로서 생활에 있어서 필수품중 하나이다.In general, the refrigerator is one of the necessities of life as a device that keeps food fresh for a certain period of time by lowering the inside of the refrigerator as the refrigerant (working fluid) repeats the refrigeration cycle of compression, condensation, expansion and evaporation.

이와 같은 냉장고는 저온/저압의 가스 냉매를 고온/고압의 가스 냉매로 승온/승압하는 압축기와, 상기 압축기로부터 유입된 냉매를 외기에 의해 응축시키는 응축기와, 다른 부분의 직경에 비해 협소한 직경으로 이루어져 상기 응축기로부터 유입된 냉매를 감압시키는 팽창밸브와, 상기 팽창밸브를 통과한 냉매가 저압상태에서 증발됨에 따라 고내의 열을 흡수하는 증발기를 기본 부품으로 하여 냉동사이클을 구성한다.Such a refrigerator includes a compressor for raising / heating a low temperature / low pressure gas refrigerant to a high temperature / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. It consists of an expansion valve for reducing the refrigerant introduced from the condenser, and the evaporator which absorbs the heat in the refrigerator as the refrigerant passing through the expansion valve in a low pressure state as a basic component constitutes a refrigeration cycle.

대부분의 냉장고는 통상 하부에 냉장실이 형성되고, 상부에 냉동실이 형성되는 구조로 이루어지는데 최근에는 냉장고가 대형화되면서 냉장고에서 직접 냉수를 취수할 수 있도록 하기 위하여 상측에 냉장실을 구비하고, 하측에 냉동실을 구비한 냉장고가 출시되고 있다.Most refrigerators have a structure in which a refrigerating chamber is formed at a lower portion of the refrigerator and a freezing chamber is formed at the upper portion of the refrigerator. In recent years, as the refrigerator becomes larger, a refrigerator is provided at the upper side and a freezing chamber at the lower side so that the cold water can be taken directly from the refrigerator. Refrigerators equipped with these are being released.

The ice maker 3 is provided. The automatic ice maker is a device that freezes water in an ice-making room (not shown) of a certain form and freezes and stores it in an ice bank (not shown) so that the user can immediately obtain ice when desired.

이와 같은 자동제빙기는 통상 냉동실(1)에 위치함으로써 사용자가 원할때 디스펜서(도시생략)를 통해 얼음을 취음할 수 있도록 구성되어 있으나, 상기 냉동실(1)이 하부에 구비된 냉장고에서는 디스펜서가 설치되어 있다하더라도 사용자가 허리를 굽혀 얼음을 얻을 수 밖에 없으므로 불편을 초래하게 된다.Such automatic ice makers are generally located in the freezer compartment 1 so that the user can pick up ice through a dispenser (not shown) when desired. However, a dispenser is installed in the refrigerator provided with the freezer compartment 1 underneath. Even if the user bends the waist to get the ice will cause inconvenience.
