상기 냉장실(5)의 바닥부에는 야채나 채소류 등의 음식물을 수납시키도록 야채통(50)이 배설되어 있고, 상기 야채통(50)의 바닥측에 는 음식물 수납시에 에어커튼을 형성하는 냉기의 유동이 차단되는 것을 방지하도록 요홈부(50a)가 형성되어 있다.At the bottom of the refrigerating chamber 5, a vegetable container 50 is disposed to accommodate foods such as vegetables and vegetables, and a cold air is formed at the bottom of the vegetable container 50 when air is stored. The recess 50a is formed to prevent the flow of the gas.
다음은 이와 같이 구성된 본 발명에 의한 냉장고의 냉기순환장치의 작용 및 효과에 대해서 설명한다.Next, the operation and effects of the cold air circulation system of the refrigerator according to the present invention configured as described above will be described.
먼저, 냉장실(5)의 도어를 개방하면 전환밸브(20)가 작동되어 송풍팬(15)의 회전에 의해 냉기가 토출덕트(19)를 통해 토출되고, 상기 냉기는 냉장실(5)의 전면부 상측으로부터 하측으로 흐르게 되어 에어커튼을 형성하고, 상기 에어커튼을 형성한 냉기는 냉장실(5)의 바닥부에 형성된 리턴덕트(21)를 통해 유입되어 냉장실(5)의 내측으로 재순환됨으로써, 에어커튼이 지속적으로 형성되어, 도어 개방에 따라 냉장실(5)내부의 냉기가 외부로 누출되는 것이 방지된다.First, when the door of the refrigerating chamber 5 is opened, the switching valve 20 is operated so that cool air is discharged through the discharge duct 19 by the rotation of the blower fan 15, and the cold air is the front part of the refrigerating chamber 5. The air curtain flows from the upper side to the lower side to form an air curtain, and the cold air having the air curtain formed therein flows through the return duct 21 formed at the bottom of the refrigerating compartment 5 and is recycled to the inside of the refrigerating compartment 5. This is continuously formed to prevent the cool air inside the refrigerating chamber 5 from leaking out as the door is opened.
한편, 야채나 채소류 등의 음식물을 수납할 때는 냉장실(5)의 바닥부에 배설된 야채통(50)을 냉장실(5)의 전면측으로 잡아당겨 음식물을 수납시킨다.On the other hand, when storing food, such as vegetables and vegetables, by pulling the vegetable container 50 disposed in the bottom of the refrigerator compartment 5 to the front side of the refrigerator compartment 5 to accommodate the food.
이때, 당겨진 야채통(50)은 하측에 형성된 요홈부(50a)에 의해 냉기가 순환되는 통로가 형성됨에 따라 냉장실(5)의 전면측에서 형성된 에어커튼이 원활하게 리턴덕트(21)로 통하게 되어 에어커튼을 계속적으로 형성한다.At this time, the pulled vegetable container 50 is a passage through which cold air is circulated by the recess 50a formed at the lower side, so that the air curtain formed at the front side of the refrigerating chamber 5 smoothly passes through the return duct 21. Continue to form air curtains.
따라서, 수용부재(31)에 야채나 채소류 등의 음식물을 수납시킬 때에도 에어커튼을 형성하는 냉기가 원활하게 순환되어 냉기가 누출되는 것을 방지함으로써, 음식물의 신선도가 저하되는 것을 효과적으로 방지한다.Therefore, even when storing foods, such as vegetables and vegetables, in the accommodating member 31, the cold air which forms an air curtain circulates smoothly and prevents cold air from leaking, and effectively prevents the freshness of food from falling.
상술한 바와 같이 본 발명에 의한 냉장고의 냉기순환장치에 의하면, 야채 또는 채소류 등을 수납하는 야채통의 일측에 요홈부를 형성하여 음식물을 수납하기 위하여 상기 야채통을 잡아당겼을 때에도 상기 요홈부를 통해 냉기가 원활하게 리턴덕트를 통과하게 됨에 따라 계속적으로 에어커튼이 형성되어 냉기가 누출되는 것을 방지할 수 있다는 매우 효과적인 발명이다.As described above, according to the cold air circulation device of the refrigerator according to the present invention, cold grooves are formed through the grooves even when the vegetables are pulled to accommodate food by forming grooves on one side of the container for storing vegetables or vegetables. As the air passes smoothly through the return duct, the air curtain is continuously formed, which prevents the leakage of cold air.
