Description

냉장고의 냉장실 냉기보상장치Cold Storage Compensator

본 발명은 냉장고의 냉장실 냉기보상장치에 관한 것으로, 보다 상세하게는 냉동실 도어의 개폐에 따라 냉동실의 냉기가 사절부을 통하여 냉장실로 공급되면서 냉장실 전면에 에어커튼을 형성하도록 한 것에 관한 것이다.The present invention relates to a refrigerating compartment cold air compensation device of a refrigerator, and more particularly, to forming an air curtain on the front side of a refrigerating compartment as cold air of the freezing compartment is supplied to the refrigerating compartment through a trimmer according to opening and closing of the freezer compartment door.

주지된 바와 같이, 냉각기실에서 생성된 냉기 공급 및 귀환의 순환구조는 도 1 에 도시되어 있다.As is well known, the circulation structure of the cold air supply and return generated in the cooler chamber is shown in FIG.

즉, 냉각기실(10)에 설치된 증발기(12)에서 냉동싸이클을 따라 순환하던 냉매의 열교환을 통하여 냉기가 생성되고, 이렇게 생성된 냉기는 냉각기실(10) 후벽 단열재속에 냉장실(R)로 연통되도록 관통형성된 메인덕트(20)를 타고 고내 분포온도에 따라 조절되는 온도조절기인 댐퍼(30)를 거쳐 멀티덕트(40)를 통하여 냉장실(R) 고내로 공급된다.That is, cold air is generated through heat exchange of the refrigerant circulating along the freezing cycle in the evaporator 12 installed in the cooler chamber 10, and the generated cold air communicates with the refrigerating chamber R in the rear wall insulating material of the cooler chamber 10. The through-formed main duct 20 is supplied into the refrigerating chamber R through the multi duct 40 via a damper 30 which is a temperature controller controlled according to the distribution temperature in the refrigerator.

그런 후에, 고내에 보관중인 음식물들과의 열교환을 통하여 온도상승되면서 온기로 변하게 되고, 이러한 온기는 사절부(50)에 형성된 리턴덕트(54a)를 타고 다시 냉각기실(10)로 귀환되는 순환을 반복하도록 되어 있다.Thereafter, the temperature rises through heat exchange with foods stored in the room, and the temperature is changed to warmth, and the warmth is returned to the cooler chamber 10 by the return duct 54a formed in the trimming section 50. It is meant to be repeated.

한편, 송풍팬(14)에 의하여 직접 냉동실(F)로 공급된 냉기는 고내를 순환한 후에 사절부(50)에 형성된 리턴덕트(54b)를 타고 냉각기실(10)로 귀환되는 순환을 마찬가지로 반복하고 있다.On the other hand, the cold air supplied directly to the freezer compartment (F) by the blowing fan (14) repeats the circulation to return to the cooler chamber (10) through the return duct (54b) formed in the trimming section 50 after circulating the interior Doing.

그런데, 상술한 바와 같은 기존 냉장고의 냉기 공급 및 귀환덕트 구조는 특히 빈번하게 개폐되는 냉장실 도어에 의해 냉장실(R)로 유입되는 외부온기에 대해 즉각적인 냉기보상을 하여주는 장치가 없어 냉장실 냉각성능이 저하되는 문제가 있었으며, 또한 도어 폐쇄후에도 고내를 정온화시키는데에 시간이 너무 많이 걸리기 때문에 온도변화에 민감한 음식물은 쉽게 손상되는 문제가 있어 왔다.By the way, the cold air supply and return duct structure of the existing refrigerator as described above is particularly low in the refrigerating room cooling performance because there is no device that provides immediate cold compensation for the external warm water introduced into the refrigerating room (R) by the frequently opened and closed doors There was a problem that, too, it takes too much time to cool the interior even after the door is closed, the food sensitive to temperature changes has been a problem that is easily damaged.

본 발명은 상술한 바와 같은 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 냉동실 도어가 개방되는 순간 냉동실의 냉기가 냉장실 내부로 강제유도되면서 냉장실 전면 상부에서 하방향으로 소정시간동안 토출되어 에어커튼을 형성함으로서 외기의 유입을 최대한 차단케 하도록 한 수단이 구비된 냉장고의 제공을 그 기술적 과제로 하는 것이다.The present invention was created in view of the above-described problems, and the air curtain is discharged for a predetermined time from the upper side of the front side of the refrigerating chamber while the freezer compartment is forced to the inside of the refrigerating chamber at the moment the freezing chamber door is opened. The technical problem is to provide a refrigerator equipped with means for blocking the inflow of outside air as possible by forming.

Means for forcibly inducing cold air to discharge cold air from the upper trimming section at the lower side of the refrigerating chamber.

이하에서는, 본 발명에 따라 선호된 일 실시예를 첨부도면을 참조하여 보다 상세하게 설명한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따라 냉동실(F)의 냉기를 냉장실(R)로 강제유도시켜 외기의 유입을 부분적으로 차단토록 하면서 냉장실에 냉기를 집중 보상할 수 있는 냉기보상장치가 사절부(50)에 구비된 상태를 도시한 냉장고의 측단면도이고, 도 3은 본 발명의 요부를 확대하여 도시한 부분 사시도이다.2 is a cold air compensator for compensating for the cold air in the refrigerator compartment by forcibly inducing cold air in the freezer compartment F to the refrigerating compartment R according to the present invention in the refrigeration unit 50. It is a side sectional view of the refrigerator showing the equipped state, and FIG. 3 is a partial perspective view showing the main part of the present invention enlarged.

본 발명은 도 2 내지 도 3 에서와 같이, 냉장고의 사절부(50)에는 냉동실(F)에서 열교환된 냉기가 냉각기실(10)로 귀환되는 통로인 냉동실 리턴덕트(80a)와, 냉장실(R)측 냉기가 귀환되는 통로인 냉장실 리턴덕트(80b)가 형성되는 바, 종래와는 달리 상기 냉장실 리턴덕트(80b)는 사절부(50)의 후측 하단 즉, 냉장실 상부 후방쪽 사절부(50)에 냉각기실(10)과 연통되도록 형성된다.2 to 3, the freezing chamber return duct 80a and the refrigerating chamber R are passages in the trimming section 50 of the refrigerator to return the cold air heat exchanged from the freezer compartment F to the cooler chamber 10. The refrigerator compartment return duct 80b, which is a passage through which cold air is returned, is formed. Unlike the related art, the refrigerator compartment return duct 80b has a rear lower end of the trimmer 50, that is, a refrigerator compartment upper rear trimmer 50. Is formed to communicate with the cooler chamber (10).

한편, 냉동실 리턴덕트(80a)는 종래의 위치보다 약간 고내 안쪽에 형성되며 그 인접선단부에는 냉동실(F)과 냉장실(R)이 연통되도록 다수의 통기공(98)이 사절부(50)를 상하로 관통형성된다.On the other hand, the freezer compartment return duct (80a) is formed slightly in the interior than the conventional position, and a plurality of vent holes (98) up and down the trimming section 50 so that the freezing chamber (F) and the refrigerating chamber (R) communicate with the adjacent front end portion thereof. Penetrating through

그리고, 상기 사절부(50)의 일측에 형성된 고정축(93)에 회동가능하게 메인기어(92)가 고정되며, 이 메인기어(92) 상측에는 메인기어(92)에 고정된 다소 작은 형태의 보조기어(94)가 상하 한쌍으로 구성되어 설치된다.In addition, the main gear 92 is rotatably fixed to the fixed shaft 93 formed on one side of the trimmer 50, and the upper side of the main gear 92 has a rather small shape fixed to the main gear 92. Auxiliary gear 94 is installed consists of a pair of upper and lower.

그리하여, 그 선단에는 돌기(97)가 돌출형성되고 후단에는 인장스프링(99a)이 고정된 작동레버(95)가 상기 보조기어(94)에 치합되게 된다.Thus, at the front end, a projection 97 protrudes, and at the rear end, an operating lever 95 having a fixed spring 99a fixed thereto is engaged with the auxiliary gear 94.

또한, 상기 통기공(98)을 개폐토록 유동가능하게 고정되며 그 일측단에는 인장스프링(99b)이 고정된 개폐레버(96)가 상기 메인기어(92)에 치합되게 된다.In addition, the vent hole 98 is fixed to be flowable to open and close, and an opening and closing lever 96 having a tension spring 99b fixed to one end thereof is engaged with the main gear 92.

아울러, 상기 작동레버(95)와 개폐레버(96)를 가이드하는 수단은 도면에 도시하지 않았으나 상기 레버(95)(96)가 직선 왕복운동이 가능토록 하여주는 가이더가 구비되어 상기 레버(95)(96)가 메인기어(92) 및 보조기어(94)에 상호 치합되어 수직방향으로 유동되도록 유도작용토록 된다.In addition, the means for guiding the actuating lever 95 and the opening / closing lever 96 are not shown in the drawing, but the levers 95 and 96 are provided with guiders for allowing linear reciprocating motions. The 96 is engaged with the main gear 92 and the auxiliary gear 94 so as to cause the guide action to flow in the vertical direction.

또한, 상기 작동레버(95)의 선단에 돌출된 돌기(97)는 냉장고의 사절부(50) 전방으로 돌출되어 있으며 냉동실도어(60)의 개폐에 따라 상기 돌기(97)가 진퇴되면서 상기 돌기(97)와 일체로 형성된 작동레버(95)를 움직이게 된다.In addition, the protrusion 97 protruding from the front end of the operating lever 95 protrudes in front of the trimming section 50 of the refrigerator, and as the protrusion 97 retreats according to the opening and closing of the freezer door 60, the protrusion ( 97 and move the operation lever 95 formed integrally with.

한편, 상기 통기공(98)의 인접상부에는 횡으로 크로스플로우팬(83)이 설치되는 바, 사절부(50) 상부로 돌출 형성된 양측의 고정구(81)에 의해 상기 팬(83)의 양단이 회동가능하게 고정되며, 이 팬(83)의 일단은 상기 일측 고정구(81) 내측에 설치된 구동모터(85)와 연결되어 있다.On the other hand, the cross-flow fan 83 is installed in the adjacent upper portion of the vent hole 98, bar both ends of the fan 83 by the fasteners 81 on both sides protruding to the upper portion of the trimming section (50). It is rotatably fixed, and one end of the fan 83 is connected to a drive motor 85 installed inside the one side fixture 81.

또한, 냉동실도어스위치(도시생략)를 제어부에 연결하고, 상기 도어스위치의 스위칭동작에 의해 상기 크로스플로우팬(83)이 연동되도록 설치된다.In addition, a freezer door switch (not shown) is connected to the control unit, and the crossflow fan 83 is installed to interlock by a switching operation of the door switch.

이러한 구성으로 이루어진 본 발명은, 냉장실 도어와는 무관하게 냉동실 도어(60)가 폐쇄되어 있는 상태일 때에는 냉동실 도어(60)가 항상 돌기(97)를 내측으로 밀고 있기 때문에 작동레버(95)가 인장스프링(99a)의 인장력을 극복하고 밀려 있으므로 메인기어(92)에 치합되어 있는 개폐레버(96)는 통기공(98)을 항상 폐쇄하고 있는 상태가 된다.According to the present invention having such a configuration, the operating lever 95 is tensioned because the freezer compartment door 60 always pushes the protrusion 97 in the freezer door 60 when the freezer compartment door 60 is closed. Since the tension force of the spring 99a is overcome and pushed, the opening / closing lever 96 engaged with the main gear 92 is in a state of always closing the vent hole 98.

따라서, 냉각모드시 냉각기실(10)의 증발기(12)에서 생성된 냉기는 냉동실로 공급된 후에 사절부(50)에 형성된 냉동실 리턴덕트(80a)를 타고 냉각기실(10)로 귀환되는 순환이 이루어지며, 한편 메인덕트(20) 및 댐퍼(30), 멀티덕트(40)를 거쳐 냉장실(R)로 공급된 냉기는 고내에 수납되어 있는 저장식품과 열교환 된 후에 온도상승되어 사절부(50) 후방에 형성된 냉장실 리턴덕트(80b)를 타고 냉각기실(10)로 귀환되는 순환을 이루게 된다.Therefore, in the cooling mode, the cool air generated in the evaporator 12 of the cooler chamber 10 is fed back into the freezer compartment 10 after being supplied to the freezer compartment by the freezer return duct 80a formed in the trimming section 50. On the other hand, the cold air supplied to the refrigerating chamber (R) through the main duct (20), the damper (30), the multi duct (40) is heat-exchanged after the heat exchanged with the stored food stored in the inside of the trimming section (50) The cooling chamber return duct 80b formed at the rear is configured to return to the cooler chamber 10.

반면에, 냉동실 도어(60)가 오픈되게 되면, 작동레버(95) 후단에 고정된 인장스프링(99b)의 인장력에 의해 상기 작동레버(95)가 사절부(50) 전방으로 이동되면서 돌기(97)가 돌출되며, 이때 작동레버(95)에 치합되어 있는 보조기어(94)가 회동되면서 그 하단에 고정된 메인기어(92)도 회동되게 된다.On the other hand, when the freezing chamber door 60 is opened, the operating lever 95 is moved forward of the trimming section 50 by the tension force of the tension spring 99b fixed to the rear end of the operating lever 95. ) Is protruded, and the main gear 92 fixed to the lower end is also rotated while the auxiliary gear 94 is engaged to the operating lever (95).

따라서, 개폐레버(96)가 그 일단에 고정된 인장스프링(99b)의 인장력이 메인기어(92)의 회동을 더욱 촉진하면서 폐쇄하고 있던 통기공(98)을 개방하게 된다.Accordingly, the tensioning force of the tension spring 99b fixed to the one end of the opening and closing lever 96 further facilitates the rotation of the main gear 92, thereby opening the vent hole 98 closed.

이와 동시에, 냉동실 도어스위치와 연동되도록 제어부에 연결된 크로스플로우팬(83)이 회동되면서 냉동실의 냉기를 강제유도하여 상기 통기공(98)을 통해 냉장실(R) 상부에서 직하방으로 강제 토출되도록 함으로서 냉장실 전면에 에어커튼을 형성하여 외기의 냉장실 내부로의 유입을 차단하게 된다.At the same time, the crossflow fan 83 connected to the control unit to be interlocked with the freezer door switch is rotated to induce cold air in the freezer compartment to be forced out of the refrigerating chamber R through the vent hole 98 directly downward. An air curtain is formed on the front surface to block the inflow of outside air into the refrigerating chamber.

그러므로, 냉장실 도어 개폐에 따라 외기가 유입되어 열손실된 냉장실에 상기 통기공을 통해 에어커튼을 형성하면서 공급된 냉동실 냉기가 온도상승된 고내온도를 보상하여 냉각시키게 됨으로서 단시간에 고내 정온화가 이루어져 냉장실 내부의 냉각균형이 유지되게 된다.Therefore, the freezer cold air supplied while forming the air curtain through the air vent in the cold room where heat is lost due to the opening and closing of the refrigerating compartment door is compensated for and cooled by the temperature rise in the high temperature, so that the inside of the refrigerating compartment is shortened. Cooling balance of is maintained.

이상에서 살펴 본 바와 같이, 본 발명에 따른 냉장고의 냉장실 냉기보상장치는, 그 선단부에 다수의 부품에 의해 냉동실의 냉기가 냉장실로 연통 공급되도록 하는 냉기공급수단이 부설되어 있어 냉장실 도어를 개방하게 되면 냉장실 도어스위치와 연동되는 크로스플로우팬이 회동되면서 냉동실의 냉기가 강제유도되어 사절부에 형성된 통기공을 통하여 냉장실 전면 상측에서 직하방으로 토출되면서 냉장실 전면에 에어커튼을 형성하게 됨으로서 고내 온기유입을 차단하면서 손실된 냉장실의 냉기를 보상토록 함으로서 이에 따라 고내 식품보관의 신선도를 향상시키는 효과가 있는 것이다.As described above, in the refrigerator compartment cold air compensator of the refrigerator according to the present invention, a cold air supply means for supplying the cold air of the freezer compartment to the refrigerator compartment by a plurality of parts at the front end thereof is provided so that the refrigerator compartment door is opened. As the crossflow fan interlocked with the refrigerating chamber door switch rotates, the cold air of the freezer compartment is forced to be discharged and discharged directly from the upper side of the refrigerating chamber front through the vent hole formed in the trimming section to form an air curtain on the front side of the refrigerating compartment to block the inflow of warm air. By compensating for the cold air lost in the refrigerating chamber, thereby improving the freshness of the food storage.
