본 고안은 냉장고에 관한 것으로, 더 상세하게는 냉동실 냉기복귀덕트와 냉장실 냉기복귀덕트를 별도로 설치하여 냉동실 냉기와 냉장실 냉기의 혼합을 방지하여 냉장실의 습기와 저장식품의 냄새가 냉동실로 옮겨가는 것을 방지하는 냉장고에 관한 것이다.The present invention relates to a refrigerator, and more particularly, by installing a freezer cold return duct and a freezer cold return duct separately to prevent mixing of the freezer cold and the cold compartment cold air to prevent the moisture of the refrigerator compartment and the smell of stored food from being transferred to the freezer. It is about the refrigerator.

종래의 냉장고는 제1도에 도시된 바와 같이, 그 내부가 중간벽(4)에 의하여 상하 구획되어 냉동실(1a)과 냉장실(1b)이 형성된 본체(1)가 마련되어 있다. 냉장실(1b)의 내부 하측에는 과일 등의 야채를 보관하기 위한 야채실(3a)이 마련되며, 야채실(3a)의 상부에는 다단의 선반(3b)이 설치되고, 본체(1)의 일측에는 냉동실(1a)과 냉장실(1b)을 개폐하기 위한 도아(2a)(2b)가 설치되어 있는 것이다. 냉동실(1a)의 후방에는 냉기를 생성하는 증발기(5)가 설치되고, 증발기(5)의 상측에는 생성된 냉기를 냉동실(1a)과 냉장실(1b)로 강제 송풍하기 위한 팬(8a)과 팬모터(8b)가 설치되어 있으며, 팬(8a)에 의하여 강제송풍되는 냉기를 냉동실(1a) 또는 냉장실(1b)로 적절히 안내하는 덕트(6a)(6b)가 냉장실(1b)과 냉동실(1a)의 후방 본체(1)에 마련되어 있는 것이다. 이때 냉장실(1b)에 대응되는 덕트(6a)에는 냉기토출구(6c)가 상하로 다수개 형성되고, 냉동실(1a) 덕트(6b)에도 다수개의 냉기토출구(6d)가 형성되며, 중간벽(4)에는 냉동실(1a)과 냉장실(1b)에서 냉각작용을 끝낸 냉기를 재냉각시키기 위하여 증발기(5)로 안내하는 복귀덕트(7a)(7b)가 마련되어 있는 것이다.In the conventional refrigerator, as shown in FIG. 1, a main body 1 is formed in which a freezer compartment 1a and a refrigerating compartment 1b are formed, the inside of which is divided up and down by an intermediate wall 4. In the lower side of the refrigerating compartment 1b, a vegetable compartment 3a for storing vegetables such as fruits is provided. A multi-stage shelf 3b is provided at an upper portion of the vegetable compartment 3a. Doors 2a and 2b for opening and closing 1a and the refrigerating chamber 1b are provided. An evaporator 5 for generating cold air is provided at the rear of the freezer compartment 1a, and a fan 8a and a fan for forcibly blowing the generated cold air into the freezer compartment 1a and the refrigerating compartment 1b above the evaporator 5. A motor 8b is provided, and ducts 6a and 6b for guiding the cool air forcedly blown by the fan 8a to the freezing chamber 1a or the refrigerating chamber 1b are the refrigerating chamber 1b and the freezing chamber 1a. It is provided in the rear main body 1. In this case, a plurality of cold air discharge ports 6c are formed in the duct 6a corresponding to the refrigerating chamber 1b, and a plurality of cold air discharge ports 6d are formed in the freezer compartment 1a duct 6b. ) Is provided with return ducts (7a) (7b) for guiding the evaporator (5) in order to recool the cold air after the cooling operation in the freezing chamber (1a) and the refrigerating chamber (1b).

이와 같이 구성된 종래의 냉장고의 냉기 순환과정을 설명하면 다음과 같다.Referring to the cold air circulation process of the conventional refrigerator configured as described above are as follows.

냉동싸이클에 의하여 증발기(5)에서 냉기가 생성되면 팬(8a)에 의하여 강제송풍되어 덕트(6a)(6b)를 따라 냉장실(1b) 또는 냉동실(1a)로 이동되어 열교환을 수행하여 냉동실(1a)과 냉장실(1b)을 빙온과 저온으로 유지시켜 냉동 또는 냉장식품을 저장보관토록 하는 것이다. 냉동실(1a)과 냉장실(1b)에서 열교환을 수행하여 온도가 상승된 냉기는 복귀덕트(7b)(7b)를 통하여 증발기(5)로 복귀되어 재냉각된 후 강제송풍되어 열교환을 반복 수행하는 것이다.When cold air is generated in the evaporator 5 by the freezing cycle, it is forcedly blown by the fan 8a and moved to the refrigerating chamber 1b or the freezing chamber 1a along the ducts 6a and 6b to perform heat exchange, thereby freezing the chamber 1a. ) And the refrigerating chamber (1b) is to keep the frozen or refrigerated food stored at ice temperature and low temperature. The cold air whose temperature is increased by performing heat exchange in the freezer compartment 1a and the refrigerating compartment 1b is returned to the evaporator 5 through the return ducts 7b and 7b, recooled, and forcedly blown to perform heat exchange. .

There was a problem of losing the intrinsic smell and vice versa that the smell of the freezer is delivered to the refrigerator. In addition, there is a problem that the cold air of the freezer compartment, which is relatively dry compared to the refrigerator compartment, deprives the moisture of the refrigerator compartment, thereby reducing the moisture of the refrigerated food, reducing the freshness of the food and shortening the storage period.

따라서 본 고안은 상기한 문제를 해결하기 위한 것으로, 본 고안의 목적은 냉동실과 냉장실의 냄새의 혼합을 방지하여 식품고유의 냄새를 유지시키며, 냉장실 수분의 상실을 방지하여 저장식품의 신선도를 향상시키고 저장기간을 연장하는 냉장고를 제공함에 있는 것이다.Therefore, the present invention is to solve the above problems, the purpose of the present invention is to prevent the mixing of the smell of the freezer compartment and the refrigerating compartment to maintain the odor of the food unique, to prevent the loss of moisture in the refrigerator compartment to improve the freshness of the stored food It is to provide a refrigerator to extend the storage period.
