About 2 heat exchanges are performed at each shelf by installing cold air outlets on the lower side of the inner duct. To cool the vegetable compartment with cold.
Description
본 고안은 냉장실에 야채실이 구비되어 있는 냉장고의 냉장실 냉기공급장치에 관한 것으로, 보다 상세하게는 냉장고의 냉장실 내부로 공급되는 냉기가 야채실로 직접 공급되지 않고 각선반을 거친 후 야채실로 공급되게 하여 냉장실의 야채실 내부의 식품빙결을 방지할 수 있도록 하는 냉장고의 냉장실 냉기공급장치에 관한 것이다.The present invention relates to a refrigerator compartment cold air supply device of a refrigerator having a vegetable compartment in a refrigerator compartment, and more specifically, to ensure that the cold air supplied into the refrigerator compartment of the refrigerator is not directly supplied to the vegetable compartment, but is supplied to the vegetable compartment after passing through each shelf. It relates to a cold room cold air supply of the refrigerator to prevent food freezing inside the vegetable compartment of the.
일반적으로, 냉장실의 냉기공급은 제1도에 도시된 바와 같이, 냉장고의 냉각시스템의 작동여부와 관계없이 냉동실 내부의 온도가 일정온도이상으로 상승하면 냉동실(20) 배면의 냉각기(15)일측에 설치된 송풍팬(16)이 작동하여 냉각기(15)측의 냉기가 메인덕트 및 사이드덕트로 안내되어 냉장실(10)의 냉기토출구를 통해 육명실, 상선반, 중선반 및 하선반과 야채실 후면으로 냉기가 토출되도록 이루어져 있다.In general, the cold air supply of the refrigerating compartment, as shown in FIG. 1, is applied to one side of the cooler 15 on the rear side of the freezing compartment 20 when the temperature inside the freezer compartment rises above a certain temperature regardless of whether the refrigerator's cooling system is operated. The installed blower fan 16 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 to the rear of the meat chamber, the upper shelf, the middle shelf, the lower shelf and the vegetable compartment through the cold air outlet of the refrigerating compartment 10. Is discharged.
냉장실의 냉기공급을 위한 냉기공급통로를 보면, 그 상단부가 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, 중선반, 하선반을 거쳐 야채실까지 공급되도록 한 것이다.In the cold air supply passage for supplying the cold air to the refrigerating compartment, the main duct whose upper end communicates with the cooler 15 side of the rear side of the freezing compartment 20 is extended downward to the center of the upper part of the rear side of the refrigerating compartment 10 and diverged from both sides thereof. 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, while the rear side of the refrigerating chamber 10 vertically cools the cold air introduced from the main duct. In other words, it is supplied to the vegetable room through the unloading shelf.
한편, 야채실에는 수분함유가 높아 빙결되기 쉬운 야채나 과일 등이 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 stored in the vegetable room, which tends to freeze due to high water content, so that the vegetable room is a container with a lid so that cold air does not come in direct contact. It is usual to make it.
그러나, 종래의 냉장고 냉기 순환구조는 냉장고의 냉장실(10) 내부의 온도가 상승되어 송풍팬(16)이 작동하게 됨으로써 냉기 공급통로로 유입된 냉기가 냉장실 내부로 토출될 경우, 약 -11~-14의 냉기가 일정시간 지속적으로 토출되므로 냉기가 직접 닿지 않더라도 매우 낮은 온도의 냉기에 의해 야채실의 야채, 과일 등의 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 blower fan 16, the cold air introduced into the cold air supply passage is discharged into the refrigerator compartment. ~ -14 Because the cold air is continuously discharged for a certain time, even if the cold air does not directly reach, there is often a problem that foods such as vegetables and fruits in the vegetable compartment are frozen by the cold air at a very low temperature, resulting in a loss of freshness or damage.
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 냉기공급장치를 제공하기 위하여 안출된 것이다.The present invention provides a refrigerating compartment cold air supply device of a refrigerator which is improved in order to prevent freezing of food in the vegetable compartment by allowing the cold air supplied from the cold air supply duct not to be directly supplied to the vegetable compartment but to be heat-exchanged through each shelf 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 폐쇄하는 한편 냉장실 상선반 배면에서부터 야채실 배면까지 내부덕트를 별도 설치하고 냉장실 배면의 상선반 위치의 냉기흡입구에는 흡입팬을 설치하며 야채실 배면에는 다수의 냉기 토출구를 형성하여서 된 것이다.In order to solve this 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 separately installs an internal duct from the rear side of the refrigerator compartment to the rear of the vegetable compartment. The cold air inlet of the position is provided with a suction fan and a plurality of cold air outlets are formed on the rear of the vegetable chamber.
또한, 상기 흡입팬은 냉동실 배면의 냉각기 측에 설치된 냉장실팬과 연동되도록하여 냉장실에 냉기가 공급되는 동안에만 선택적으로 작동되도록 한 것이다.In addition, the suction fan is to be interlocked with the refrigerating chamber fan installed on the cooler side of the freezer compartment to selectively operate only while cold air is supplied to the refrigerating chamber.
이는 냉장고 전체의 각 구성요소를 제어하는 도시되지 않은 제어부의 작용에 이루어지며, 상기와 같은 송풍팬과 흡입팬을 동시에 작동시키기 위하여 상기 제어부는 상기 송풍팬과 흡입팬에 작동제어신호를 동시에 출력하게 되는 바, 이에 관한 구체적인 설명은 통상적인 것이므로 여기서는 생략한다.This is done by the operation of a control unit (not shown) that controls each component of the entire refrigerator, and in order to operate the blower fan and the suction fan at the same time, the control unit simultaneously outputs operation control signals to the blower fan and the suction fan. Detailed description thereof will be omitted herein because it is conventional.
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 고안에 따른 냉장고의 냉장실 내부덕트의 설치상태도이다.2 is a state diagram of the installation of the internal duct of the refrigerator compartment of the refrigerator according to the present invention.
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.
또한 냉장실(10) 상선반 배면위치에 형성된 내부덕트(1)의 냉기흡입구에는 냉장실(10) 내부의 냉기를 흡입하기 위한 흡입팬(2)이 설치되며 내부덕트(1)의 하단부는 양측으로 연장되면서 다수, 예를 들면 양측으로 각각 5개씩 냉기토출구(3)가 야채실 배면을 향하도록 형성되어 있다.In addition, a suction fan 2 for sucking cold air in the refrigerating chamber 10 is installed at the cold air suction port of the inner duct 1 formed at the rear side of the upper shelf of the refrigerating chamber 10, and the lower end of the inner duct 1 extends to both sides. While being large, for example, each of the five cold air outlets 3 on both sides is 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 송풍팬(16)이 작동하여 냉각기 측의 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 blower fan 16 installed on the cooler 15 side of the rear side of the refrigerating compartment 20 is operated, so that the cold air on the cooler 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 각선반을 거쳐 열교환된 후, 더워진 냉기는 상승하여 냉장실(10) 전면측 상부의 냉기흡입구(4)로 유입되어 리턴덕트(5)를 통하여 냉각기(15)측으로 복귀하게 된다.Then, the discharged cold air is heat-exchanged through the chamber and the shelf, the hot air rises and flows into the cold air inlet 4 of the upper side of the front side of the refrigerating chamber 10, the cooler 15 through the return duct (5) Return to the side.
그러나, 본 고안에서는 냉장실(10)내부에 상술한 내부덕트(1) 및 흡입팬(2)을 설치하였고, 상기한 바와 같이 도시되지 않은 제어부에서 송풍팬(16)과 흡입팬(2)에 동시에 작동신호를 송출하게 되면 냉각기(15) 일측에 설치된 송풍팬(16)의 작동과 동시에, 냉장실(10) 상선반 위치의 배면 측에 설치된 내부덕트(1)의 흡입팬(2)이 작동하게 된다.However, in the present invention, the above-described internal duct 1 and the suction fan 2 are installed in the refrigerating chamber 10, and the blower fan 16 and the suction fan 2 are simultaneously provided in the control unit (not shown). When the operation signal is sent, the suction fan 2 of the inner duct 1 installed at the rear side of the upper shelf position of the refrigerating chamber 10 is operated at the same time as the blower fan 16 installed at one side of the cooler 15 is operated. .
따라서, 기존의 냉기공급덕트를 통하여 냉장실(10) 내부로 공급되어 열교환후 리턴덕트(5)의 냉기흡입구(4)측으로 상승하는 냉기중 일부가 흡입팬(2)에 의해 내부덕트(1)로 유입되게 된다.Therefore, a part of the cold air supplied into the refrigerating chamber 10 through the existing cold air supply duct and rising to the cold air inlet 4 side of the return duct 5 after heat exchange is transferred to the internal duct 1 by the suction fan 2. It will flow in.
이어서, 흡입된 냉기는 냉장실(10) 내부덕트(1)를 통해 하강하여 야채실 배면에 횡으로 연설된 냉기토출구(3)를 통하여 야채실 배면 측으로 재토출하게 된다.Subsequently, the sucked cold air descends through the internal duct 1 of the refrigerating chamber 10 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 2정도이다.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. About 2 that can be optimally maintained It is enough.
그리고, 냉장실(10)의 배면에 설치된 내부덕트(1)를 통하여 야채실로 공급된 냉기는 열교환된 후 냉장실(10) 내부 전면측을 따라 상승하면서, 기존의 냉기 공급덕트에서 토출되어 열교환된 후 내부덕트(1)의 흡입팬(2)에 의해 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 installed on the rear side of the refrigerating compartment 10 is heat-exchanged and then rises along the front side of the refrigerating compartment 10, and is discharged from the existing cold air supply duct to be heat-exchanged. It joins the cold air which is not sucked by the suction fan 2 of the duct 1, flows into the cold air suction opening 4 of the upper side of the front side of the refrigerating chamber 10, and returns to the cooler 15 side via the return duct 5.
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 유입되지 못하고 냉장실(10) 내부전면측을 따라 상승되므로, 내부덕트(1)의 흡입팬(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 from the vegetable compartment side again by the cold air discharged on the back 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 suction fan of the inner duct 1 In (2), it is hardly inhaled.
따라서, 야채실에는 기존의 냉기공급덕트에서 토출되어 열교환이 이루어진 약 2정도의 냉기중 일부만이 유입되게 되어 야채실 내부의 식품 신선도가 보장되게 된다.Therefore, the vegetable chamber is discharged from the existing cold air supply duct to heat exchange about 2 Only part of the cold air is introduced to ensure the freshness of the food inside the vegetable compartment.
아울러, 냉장실(10) 내부의 냉기는 흡입팬(2)에 의해 유입되어 야채실로 토출되고 리턴덕트(5)로 복귀하는 과정에서 내부교반이 활성화되어 전체적으로 정온유지효과도 기대할 수 있는 것이다.In addition, the cold air inside the refrigerating chamber 10 is introduced by the suction fan (2) is discharged into the vegetable chamber and the internal stirrer is activated in the process of returning to the return duct (5) can also expect the effect of maintaining the overall temperature.
이상에서 설명한 바와 같이, 본 고안은 기존의 냉기공급덕트의 야채실측 냉기토출구를 폐쇄하는 대신에 냉장실 배면 상선반위치에서부터 야채실 배면에까지 내부덕트를 설치하고 그 상부의 냉기흡입구에 흡입팬을 설치하고 하단부에는 양측으로 연장되며 양측에 각각 다수의 냉기 토출구를 형성하여 야채실에 냉기가 공급되도록 함으로써, 야채실의 식품빙결이 방지되어 신선도를 유지할 수 있음은 물론 냉장실 냉기교반작용으로 정온유지효과가 있다.As described above, in the present invention, instead of closing the cold air outlet of the vegetable compartment side 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 a suction fan is installed at the cold air inlet of the upper portion, By extending to both sides and forming a plurality of cold air outlets on each side to supply the cold air to the vegetable compartment, the freezing of the vegetable compartment can be prevented to maintain freshness as well as to maintain the coolness of the cold room stirring action.
