Description
본 고안은 냉장고의 냉기순환 덕트에 관한 것으로, 보다 상세하게는 냉장실의 야채실 내부의 식품빙결을 방지할 수 있도록 기존의 냉기순환용 덕트에 추가로 설치되는 냉장고의 냉장실 내부덕트에 관한 것이다.The present invention relates to a cold air circulation duct of a refrigerator, and more particularly to a refrigerator compartment internal duct of the refrigerator additionally installed in the existing cold air circulation duct to prevent food freezing inside the vegetable compartment of the refrigerator compartment.
일반적으로 냉장실의 냉기공급은 제1도에 도시된 바와 같이, 냉장고의 냉각시스템의 작동여부와 관계없이 냉동실 내부의 온도가 일정온도이상으로 상승하면 냉동실(20) 배면의 냉각기(15)일측에 설치된 냉장실팬(6)이 작동하여 냉각기(15)측의 냉기가 메인덕트 및 사이드덕트로 안내되어 냉장실(10)의 냉기토출구를 통해 육명실, 상선반, 중선반 및 하선반과 야채실 후면으로 냉기가 토출됨으로써 이루어지게 된다.In general, the cold air supply of the refrigerating compartment is installed at one side of the cooler 15 on the rear side of the freezer compartment 20 when the temperature inside the freezer compartment rises above a predetermined temperature regardless of whether the refrigerator's cooling system is operated as shown in FIG. 1. The refrigerating chamber fan 6 is operated so that the cool air on the side of the cooler 15 is guided to the main duct and the side duct, and the cold air is discharged through the cold air outlet of the refrigerating chamber 10 to the rear of the meat chamber, the upper shelf, the middle shelf, the lower shelf and the vegetable compartment. It is made by discharging.
냉장실의 냉기공급을 위한 냉기공급통로를 보면, 그 상단부에 냉동실(20)배면의 냉각기(15)측에 연통된 메인덕트가 냉장실(10) 배면상부 위치 중앙까지 하향연장되고 그 부분에서 양측으로 분기되어 사이드덕트로 안내되면서 냉동실(20)후방측벽에 상하로 형성된 냉기토출구를 통해 냉기가 토출되는 한편, 냉장실(10)배면은 메인덕트로부터 유입된 냉기가 수직하강하면서 육명실, 상선반, 중산반, 하선반을 거쳐 야채실까지 공급되도록 한 것이다.In the cold air supply passage for supplying the cold air to the refrigerating compartment, the main duct connected to the cooler 15 side of the rear side of the freezing compartment 20 at the upper end thereof is extended downward to the center of the upper portion of the rear side of the refrigerating compartment 10 and branched to both sides from the portion. The cold air is discharged through the cold air outlet formed on the rear side wall of the freezing chamber 20 while being guided to the side duct, and the rear side of the refrigerating chamber 10 has the cold air flowing from the main duct descending vertically. In other words, it is supplied to the vegetable room through the unloading shelf.
한편, 야채실에는 수분함유가 높아 빙결되기 쉬운 야채나 과일등이 수납되므로 냉기가 직접 닿지 않도록 야채실은 뚜껑이 있는 용기로 되어 있고, 토출된 냉기가 직접 접촉하게 되는 부분인 야채실의 후측벽은 2중벽으로 하는 것이 통상적이다.On the other hand, vegetables and fruits are easily stored in the vegetable room because they contain moisture, so the vegetable room is a container with a lid so that cold air does not touch directly. It is usual to make it.
그러나, 종래의 냉장고 냉기 순환구조는 냉장고의 냉장실(10) 내부의 온도가 상승되어 냉장실팬(16)이 작동하게 됨으로써 냉기 공급통로로 유입된 냉기가 냉장실 내부로 토출될 경우, 약 -11℃∼-14℃의 냉기가 일정시간 지속적으로 토출되므로 냉기가 직접 닿지않더라도 매우 낮은 온도의 냉기에 의해 야채실의 야채, 과일등의 식품이 빙결되어 신선도가 떨어지게 되거나 손상되는 문제점이 종종 발생된다.However, in the conventional refrigerator cold air circulation structure, when the temperature inside the refrigerator compartment 10 of the refrigerator is raised to operate the refrigerator compartment fan 16, the cold air introduced into the cold air supply passage is discharged into the refrigerator compartment. Since cold air of -14 ℃ is continuously discharged for a certain time, there is often a problem that freshness of the vegetables, fruits and the like in the vegetable room are frozen due to cold of very low temperature even if the cold air does not directly reach.
본 고안은 냉기공급덕트에서 공급되는 냉기가 야채실로 직접 공급되지 않고 각선반을 거쳐 열교환된 후 야채실로 공급되게 함으로써 야채실내의 식품의 빙결을 방지할 수 있게 개선한 냉장고의 냉장실 냉기공급덕트를 제공하기 위하여 안출된 것이다.The present invention provides a refrigerator cold air supply duct of the refrigerator which is improved to prevent freezing of food in the vegetable compartment by allowing the cold air supplied from the cold air supply duct to be heat-exchanged through the shelves and then to the vegetable compartment. It was designed to do so.

이와 같은 과제를 해결하기 위하여, 본 고안의 냉장고의 냉장실 내부덕트는 기존의 냉기공급덕트의 야채실 냉기공급통로를 폐쇄하고 냉장실 성산반 배면에서부터 야채실 배면까지 내부덕트를 별도 설치하고 냉장실 배면의 상선반 위치의 냉기흡입구에는 흡입용 측류송풍기를 설치하고 야채실 배면에는 다수의 냉기 토출구를 형성하여서 된 것이다.In order to solve such a problem, the refrigerator's internal duct of the refrigerator of the present invention closes the vegetable room cold air supply passage of the existing cold air supply duct, and installs an internal duct separately from the rear side of the refrigeration room to the rear of the vegetable room and positions the shelf on the rear side of the refrigerator compartment. The cold air inlet of the suction side flow blower is installed, and the rear of the vegetable chamber is formed by forming a plurality of cold air outlet.
또한, 상기 흡입용 측류송풍기는 냉동실 배면의 냉각기측에 설치된 냉장실팬과 연동되도록하여 냉장실에 냉기가 공급되는 동안에만 선택적으로 작동되도록 한 것이다.In addition, the suction side flow blower is to be selectively operated only while the cold air is supplied to the refrigerating compartment by interlocking with the refrigerating compartment fan installed on the cooler side of the freezer compartment rear.
이하, 본 고안의 실시예를 첨부한 도면을 참조하여 보다 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in more detail.
제2도는 본 고안 냉장고의 냉장실(10) 내부덕트의 설치상태도이다.2 is an installation state diagram of the internal duct of the refrigerator compartment 10 of the present invention refrigerator.
도시된 바와 같이, 냉장실(10) 배면 상선반위치에서부터 야채실 배면위치에까지 수직연장된 내부덕트(1)가 설치되어 있다.As shown in the drawing, the inner duct 1 vertically extended from the upper shelf position to the rear surface of the vegetable compartment 10 is installed.
냉장실(10) 상선반 배면위치에 형성된 내부덕트(1)의 냉기흡입구에는 냉장실(10) 내부의 냉기흡입용 측류송풍기(2)가 설치되며 내부덕트(1)의 하부는 양측으로 연장되면서 다수, 예를 들면 양측으로 각각 5개씩의 냉기토출구(3)가 야채실 배면을 향하도록 형성되어 있다.The cold air suction port of the internal duct 1 formed at the rear surface of the refrigerating chamber 10 is installed with a cold air suction side flow blower 2 inside the refrigerator compartment 10, and the lower portion of the internal duct 1 extends to both sides, For example, five cold air outlets 3 on each side are formed to face the rear of the vegetable chamber.
이하에서, 제3도를 참조하여 본 발명에 따른 냉장고의 냉장실 냉기공급 및 냉기순환에 대하여 설명한다.Hereinafter, with reference to Figure 3 will be described in the refrigerator compartment cold air supply and cold air circulation of the refrigerator according to the present invention.
냉장실(10) 내부가 일정온도 이상으로 상승하면, 냉장실(20) 배면의 냉각기(15)측에 설치된 냉장실팬(16)이 작동하여 냉각기측의 냉기가 기존의 냉기 공급덕트를 통하여 냉장실(10) 내부로 공급되는데, 야채실측의 기존의 냉기토출구는 폐쇄하였으므로 육명실 및 각선반측으로만 냉기가 공급된다.When the inside of the refrigerating compartment 10 rises above a certain temperature, the refrigerating compartment fan 16 installed on the cooler 15 side of the refrigerating compartment 20 is operated so that the cold side of the refrigerating machine side passes through the existing cold air supply duct. Since the existing cold air outlet on the vegetable compartment side is closed, the cold air is supplied only to the meat chamber and the shelf side.
그리고, 토출된 냉기는 육명실 및 각 선반을 거쳐 열교환된 후, 더워진 냉기는 상승하여 냉장실(10) 전면측 상부의 냉기흡입구(4)로 유입되어 리턴덕트(5)를 통하여 냉각기(15)측으로 복귀하게 된다.After the discharged cold air is heat-exchanged through the six-room and each shelf, the hot air rises and enters the cold air intake 4 at the upper side of the front side of the refrigerating chamber 10, and the cooler 15 is returned through the return duct 5. Return to the side.
그러나, 본 고안에서는 냉장실(10) 내부에 상술한 내부덕트(1) 및 측류송풍기(2)를 설치하였으므로, 냉각기(15) 일측에 설치된 냉장실팬(16)의 작동과 동시에, 냉장실(10) 상선반 위치의 배면측에 설치된 내부덕트(1)의 측류송풍기(2)가 작동하게 된다.However, in the present invention, since the above-described internal duct 1 and the side blower 2 are installed in the refrigerating chamber 10, the refrigerator compartment fan 16 installed on one side of the cooler 15 is operated at the same time. The side flow blower 2 of the inner duct 1 installed on the rear side of the shelf position is operated.
따라서, 기존의 냉기공급덕트를 통하여 냉장실(10) 내부로 공급되어 열고환후 리턴덕트(5)의 냉기흡입구(4)측으로 상승되는 냉기중 일부가 흡입용 측류송풍기(2)에 의해 내부덕트(1)로 유입되게 된다.Therefore, a part of the cold air that is supplied to the inside of the refrigerating chamber 10 through the existing cold air supply duct and opened up and then lifted up to the cold air intake port 4 side of the return duct 5 is internal duct 1 by the side flow blower 2 for intake. ) Will flow into.
이어서, 흡입된 냉기는 냉장실(1) 내부덕트(1)를 통해 하강하여 야채실 배면에 횡으로 연설된 냉기토출구(3)를 통하여 야채실 배면측으로 재토출되게 된다.Subsequently, the sucked cold air descends through the internal duct 1 of the refrigerating chamber 1 and is re-discharged to the vegetable chamber rear side through the cold air discharge port 3 transversely oriented to the rear of the vegetable chamber.
그리하여, 야채실에는 기존의 냉기공급통로로부터의 냉기가 직접 공급되지 않고 냉장실에서 열교환된 냉기가 공급되는 것이고, 이렇게 공급되는 냉기의 온도는 냉장실(10) 각선반에서 열교환이 이루어진 냉기이므로 야채실의 신선도를 최적으로 유지시킬 수 있는 약 2℃정도이다.Thus, the cold air from the existing cold air supply passage is not directly supplied to the vegetable compartment, but the cold air heat-exchanged in the refrigerating compartment is supplied to the vegetable compartment. It is about 2 ℃ that can be optimally maintained.
그리고, 냉장실(10)의 내부덕트(1)를 통하여 야채실로 공급된 냉기는 열교환된 후 냉장실(10) 내부 전면측을 따라 상승하면서, 기존의 냉기 공급덕트에서 토출되어 열교환된 후 내부덕트(1)의 측류송풍기(2)에 흡입되지 않은 냉기와 합류하여 냉장실(10) 전면측 상부의 냉기흡입구(4)로 유입되어 리턴덕트(5)를 거쳐 냉각기(15)측으로 복귀한다.The cold air supplied to the vegetable compartment through the internal duct 1 of the refrigerating compartment 10 is heat-exchanged and then rises along the front side of the inside of the refrigerating compartment 10, and is discharged from the existing cold air supply duct and heat-exchanged. The cold air flows into the cold air intake port 4 on the front side of the refrigerating chamber 10 and returns to the cooler 15 side through the return duct 5 after joining the cold air that is not sucked into the side flow blower 2).
상술한 냉장실의 냉기순환에 있어서, 내부덕트(1)를 통하여 야채실측으로 토출되고 열교환된 냉기는 야채실 전면 즉, 도어측으로 배출되는데, 냉각기(15)측으로부터 기존의 냉기공급덕트를 통하여 냉장실(10) 배면 및 후방측면에 토출되는 냉기에 의해 야채실측에서 재차 열교환되어 상승되는 냉기가 냉장실(10) 안쪽으로 유입도지 못하고 냉장실(10) 내부전면측을 따라 상승되므로, 내부덕트(1)의 측류송풍기(2)에는 거의 흡입되지 않게 된다.In the above-described cold air circulation of the refrigerating compartment, the cold air discharged to the vegetable compartment side through the internal duct 1 and heat exchanged is discharged to the front of the vegetable compartment, that is, the door side, from the cooler 15 side through the existing cold air supply duct. The cold air discharged by heat exchange from the vegetable compartment side again by the cold air discharged on the rear and rear sides does not flow into the refrigerating compartment 10 but rises along the inside front side of the refrigerating compartment 10, so that the side blower of the inner duct 1 In (2), it is hardly inhaled.
따라서, 야채실에는 기존의 냉기공급덕트에서 토출되어 열교환이 이루어진 약 2℃ 정도의 냉기중 일부만이 유입되게 되어 야채실 내부의 식품 신선도가 보장되게 된다.Therefore, only part of the cold air of about 2 ° C., which is discharged from the existing cold air supply duct and heat exchanged, is introduced into the vegetable compartment, thereby ensuring food freshness inside the vegetable compartment.
아울러, 냉장실(10) 내부의 냉기는 측류송풍기(1)에 의해 유입되어 야채실로 토출되고 리턴덕트(5)로 복귀하는 과정에서 냉기의 냉장실(10) 내부교반이 활성화되어 전체적으로 정온유지효과도 기대할 수 있는 것이다.In addition, in the process of returning the cold air inside the refrigerating chamber 10 by the side flow blower 1 to the vegetable chamber and returning to the return duct 5, the internal stirring of the cold room 10 is activated, and thus the overall temperature maintaining effect is also expected. It can be.
이상에서 설명한 바와 같이, 본 고안은 기존의 냉기공급덕트의 야채실측냉기토출구를 폐쇄하는 대신에 냉장실 배면 상선반위치에서부터 야채실 배면에까지 내부덕트를 설치하고 그 상부의 냉기흡입구에 흡입용 측류송풍기를 설치하고 하부에는 양측으로 연장되며 양측에 각각 다수의 냉기 토출구를 형성하여 야채실에 냉기가 공급되도록 함으로써, 야채실의 식품빙결이 방지되어 신선도를 유지할 수 있음은 물론 냉장실 냉기교반작용으로 정온유지효과가 있는 유용한 고안이다.As described above, the present invention, instead of closing the vegetable compartment cold air outlet of the existing cold air supply duct, the inner duct is installed from the upper shelf position of the refrigerating compartment to the rear of the vegetable compartment, and the suction side flow blower is installed at the cold air inlet of the upper portion. And it extends to both sides at the bottom and forms a plurality of cold air outlets on each side so that the cold air is supplied to the vegetable compartment, the freezing of the vegetable compartment can be prevented to maintain the freshness, as well as the cold room stirring effect is useful It is devised.
본 고안은 냉장고의 냉장실 내부로 공급되는 냉기가 야채실로 직접 공급되지 않고 각선반을 거친 후 야채실로 공급되게 함으로써 야채실내의 식품빙결을 방지할 수 있는 냉장고의 냉장실 내부덕트의 제공을 그 목적으로 한다.The object of the present invention is to provide an internal duct of the refrigerator compartment that can prevent food freezing in the vegetable compartment by allowing the cold air supplied into the refrigerator compartment of the refrigerator not to be directly supplied to the vegetable compartment but to the vegetable compartment after passing through each shelf. .
