본 고안은 냉장고에 있어서, 증발기 설치구조의 개선에 관한 것으로서, 특히 냉기를 발생하는 증발기에 고내를 순환하는 냉기중에 포함된 수분이 착상되어 냉각효율을 저하시키는 것을 방지하기 위하여 증발기를 냉각전용의 증발기와 착상전용의 증발기로 분리시켜 설치하도록 한 냉장고의 증발기 설치구조에 관한 것이다.The present invention relates to an improvement in the evaporator mounting structure of the refrigerator, and in particular, to prevent the moisture contained in the cold air circulating inside the evaporator that generates cold air from being deformed, thereby lowering the cooling efficiency. And relates to an evaporator installation structure of the refrigerator to be installed separately from the evaporator dedicated to implantation.

일반적으로 간냉식 냉장고는 덕트내의 적소에 하나의 증발기를 설치하여 이로부터의 냉기를 송풍팬에 의하여 냉동실 및 냉장실로 순환시키도록 되어 있다.In general, the intercooled refrigerator is provided with one evaporator in place in the duct to circulate the cold air therefrom to the freezing compartment and the refrigerating compartment by a blower fan.

이러한 냉장고에 있어서 냉동실 및 냉장실을 순환하여온 냉기에는 수분이 포함되어 있게 되고 동 냉기가 증발기를 다시 거칠 때 그에 포함되어 있는 수분의 증발기에 성에로 착상되어 증발기의 냉각효율을 떨어뜨리게 된다.In such a refrigerator, the cold air that circulates in the freezer compartment and the refrigerating compartment contains water, and when the cold air passes through the evaporator again, it is frosted on the evaporator of the moisture contained therein to reduce the cooling efficiency of the evaporator.

따라서, 이러한 냉장고는 대부분 그 증발기에 착상되는 성에를 주기적으로 제거시켜 주기 위한 히터를 증발기와 인접한 곳에 설치구비하게 된다.Therefore, most of these refrigerators are provided with a heater adjacent to the evaporator to periodically remove the frost formed on the evaporator.

And a blower fan 14 to install the cold air generated by the evaporator 12 into the inside of each of the refrigerators 2 and 3 so that the heater 13 is operated at regular intervals during the operation of the refrigerator. To remove the frost formed on the evaporator 12, but after the heater 13 is operated once, the frost formed on the evaporator 12 is not removed until the next operation, and the cooling efficiency of the evaporator 12 is reduced. Is dropped, and if the heater 13 is operated too often to solve this problem, Excessive consumption of power, as well as the problem that the overall performance of the refrigerator is accompanied.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 냉동실 및 냉장실을 순환하고 덕트내로 들어온 더운 냉기가 증발기로 들어가는 입구 적소에 착상전용 증발기를 별도로 설치하여 착상을 전담하게 함으로써 냉각전용 증발기의 냉각효율을 향상시킬 뿐만 아니라, 제상주기의 시간을 연장시켜 전력소비를 절감할 수 있는 더욱 개선된 냉장고의 증발기 설치구조를 제공할 목적으로 안출된 것이다.The present invention circulates the freezer compartment and the refrigerating compartment in order to solve the conventional problems as described above, and installs an evaporator exclusively for implantation at the inlet location where the hot cold air entering the duct enters the evaporator, thereby deciding the cooling efficiency of the evaporator dedicated to cooling. Not only to improve, but also to provide a more improved refrigerator evaporator installation structure that can reduce the power consumption by extending the defrost cycle time.

상기의 목적을 달성하기 위한 본 고안은 냉장고의 후벽 및 격벽에 냉기순환덕트가 구성되고 이 덕트의 각 적소에 냉각전용증발기와 착상전용 증발기를 분리하여 설치한 특징이 있다.The present invention for achieving the above object is characterized in that the cold air circulation duct is configured on the rear wall and the partition wall of the refrigerator and separately installed for the cooling evaporator and the implantation evaporator in each location of the duct.
