Description

양문형 냉장고의 냉장실 과냉방지장치{Excessive Cooling prevention apparatus of refrigeration room in the side-by-side type refrigerator}Excessive Cooling prevention apparatus of refrigeration room in the side-by-side type refrigerator}

본 발명은 양문형 냉장고의 냉장실 과냉방지장치에 관한 것으로서, 더욱 상세하게는 양문형냉장고에서 냉각기의 냉기가 냉장실로 과도하게 흘러들어가 냉장실이 과냉되는 것을 방지하는 과냉장지장치에 대한 것이다.The present invention relates to an apparatus for preventing overcooling of a refrigerating compartment of a double-door refrigerator, and more particularly, to an overcooling apparatus for preventing a refrigerating compartment from being overcooled by excessive flow of cold air from a refrigerating refrigerator into a refrigerating compartment.

일반적으로, 양문형 냉장고는 비교적 큰 용량을 가지고 여러가지 기능이 복합적으로 구비된 것으로서, 냉동실과 냉장실이 각각 종방향으로 수직되게 냉장고의 좌우측에 설치되고 냉동실의 배면에는 증발기가 장착되는 냉각기실이 구비되어 냉동실과 냉장실의 고내 공기를 하부측으로 흡입함과 동시에 상부측으로 토출되게 하여 각 고내로 순환시킴으로써 냉장기능과 냉동기능을 각각 수행하도록 구성된 것이다. 이러한 양문형 냉장고의 냉기공급구조를 보여주는 도면이 도 1에 도시되어있다. In general, a two-door refrigerator has a relatively large capacity and is a combination of various functions, and the freezer compartment is provided on the left and right sides of the refrigerator such that the freezer compartment and the refrigerating compartment are vertically perpendicular to each other in the vertical direction, and a freezer compartment having an evaporator mounted on the rear side of the freezer compartment. It is configured to perform the refrigerating function and the freezing function, respectively, by inhaling the air in the refrigerator compartment to the lower side and simultaneously discharging it to the upper side. 1 is a view illustrating a cold air supply structure of the double door refrigerator.

도 1에 도시된 바와 같이, 종래의 양문형 냉장고의 냉기공급구조는 각각 수직으로 평행하게 형성되고 사절부(6)에 의해 분리구획되는 냉동실(F) 및 냉장실(R)과, 냉동실(F)의 후방에 냉동실(F)과 별개의 공간을 형성하도록 분리구획되고 증발기(2) 및 송풍팬(3)이 설치되는 냉각기실(1)과, 냉각기실(1)에서 생성된 냉기를 냉장실(R)로 공급하도록 사절부(6)의 상부측에 형성되는 공급덕트(4)와, 냉장실(R)에서 온도상승된 냉기가 냉각기실(1)로 귀환되는 통로로서 사절부(6)의 하부측에 형성되는 흡입덕트(5)와, 공급덕트(4)의 냉장실측에 설치되어 공급되는 냉기량을 조절하는 댐퍼(8)를 포함하여 구성된다. As shown in FIG. 1, the cold air supply structure of the conventional double door refrigerator has a freezing compartment F and a refrigerating compartment R, which are each formed in parallel and vertically and separated by a trimming section 6, and a freezing compartment F. The cooler chamber 1 which is separated and formed so as to form a space separate from the freezing chamber F at the rear, and the evaporator 2 and the blower fan 3 are installed, and the cold air generated in the cooler chamber 1 is the refrigerating chamber R. The supply duct 4 formed at the upper side of the trimming section 6 so as to be supplied to the cooling section and a passage through which the cold air whose temperature has risen in the refrigerating chamber R is returned to the cooler chamber 1 at the lower side of the trimming section 6. And a damper (8) for adjusting the amount of cold air provided and supplied to the refrigerating chamber side of the supply duct (4).

증발기(2)에서 생성된 냉기는 송풍팬(3)에 의해 냉동실(F) 및 냉장실(R)로 공급되고, 각 고내에 수납중인 저장식품 등과 열교환에 의해 온도상승된 냉기는 다시 증발기(2)측으로 귀환되는 순환을 반복하면서 냉장고내를 냉각시킨다.The cold air generated by the evaporator 2 is supplied to the freezing chamber F and the refrigerating chamber R by the blower fan 3, and the cold air that has risen in temperature by heat exchange with the stored foods stored in each chamber is evaporated again. The inside of the refrigerator is cooled while repeating the circulation returned to the side.

또한, 냉장실 내부에는 저장식품 등을 올려 보관하기 위한 복수개의 선반 (미도시)이 구비되어 있으며, 그 하부에는 야채를 보관하기 위한 별도의 야채저장상자 (13)가 설치되는 것이 일반적이다.In addition, the inside of the refrigerating chamber is provided with a plurality of shelves (not shown) for storing stored foods, etc., a lower vegetable storage box 13 for storing vegetables is generally installed below.

양문형 냉장고의 경우 냉장실에서 온도상승된 냉기는 냉장실의 측면 임의의 위치에 형성된 냉기 흡입구(5)를 통해 귀환되어 일반적인 냉장고에 비해 냉기 토출구 및 흡입구의 위치를 자유롭게 구성할 수 있다는 장점이 있다.In the case of a double-door refrigerator, the cold air that has risen in temperature in the refrigerating compartment is returned through the cold air intake port 5 formed at an arbitrary position of the side of the refrigerating compartment, so that the positions of the cold air discharge port and the intake port can be freely configured in comparison with the general refrigerator.

그러나 이러한 장점에도 불구하고 냉장실이 적정돈도가 되어 냉장실팬이 정지된 경우에도 냉기 흡입구(5)를 통하여 냉동실(F)의 냉기가 냉장실로 유입됨으로써 냉장실에 과냉이 발생하는 경우가 발생하게 되었다.However, in spite of these advantages, even when the refrigerating compartment is at an appropriate level and the refrigerating compartment fan is stopped, the cold air of the freezing compartment F flows into the refrigerating compartment through the cold air inlet 5, thereby causing subcooling in the refrigerating compartment.

본 발명은 상기에 기술된 종래기술의 단점을 극복하고자 착안된 것으로써, 양문형 냉장고에 있어서 냉동실의 냉기가 냉장실로 흘러들어가 냉장실이 과냉되지 않도록 하는 냉장실 과냉방지장치를 제공함에 그 목적을 두고 있다.The present invention has been made in view of the above-mentioned disadvantages of the prior art, and aims to provide a refrigerating compartment subcooling preventing device in the cold door of the freezer compartment flows into the refrigerating compartment in the double door refrigerator to prevent the refrigerating compartment is not overcooled.

본 발명은 상기 언급된 목적을 달성하기 위하여 냉동실 냉기가 냉장실의 냉장실팬이 구동될때만 체크밸브가 작동하여 상승한 냉기를 냉동실로 순환시키는 과냉장지장치를 제공한다.The present invention provides a supercooling apparatus for circulating the raised cold air to the freezing chamber by operating a check valve only when the freezing compartment cold air is driven in the refrigerating compartment fan of the refrigerating compartment to achieve the above-mentioned object.

이를 위하여 냉동실팬과 냉장실팬이 구비된 양문형 냉장고에 있어서, 양문형 냉장고의 냉장실 과냉방지장치에는, 냉동실과 냉장실을 분할하는 사절부의 하단에 형성되는 온기통로부와, 상기 온기통로부에 설치되어 냉장실의 냉기를 냉동실로 유입시키며 냉장실팬과 연동하여 작동하는 구동수단을 구비한 체크밸브 등이 포함된다. To this end, in a double-door refrigerator equipped with a freezer compartment fan and a refrigerating compartment fan, in the refrigerator compartment subcooling prevention device of the double-door refrigerator, a warmer passage portion formed at the lower end of the trimming section for dividing the freezer compartment and the refrigerating compartment, and installed in the warmer passage portion It includes a check valve having a drive means for operating in conjunction with the refrigerating chamber fan and the cold air into the freezer compartment.

이하 첨부된 발명을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the attached invention.

도 2는 본 발명에 따른 냉기공급구조를 도시한 종단면도로써, 냉각기(21)에서 발생한 냉기가 순환되는 구조를 보여준다. 2 is a longitudinal sectional view showing a cold air supply structure according to the present invention, showing a structure in which cold air generated in the cooler 21 is circulated.

상기 냉기 순환구조에 따른 순환과정을 설명하면 냉각기(21)에서 발생한 냉기는 냉동실팬(22)과 냉장실팬(23)에 의하여 각각 냉동실과 냉장실을 순환하게 된다. 이러한 순환에 의하여 냉동실과 냉장실이 냉각된다. 물론 본체(20)에는 냉매를 고온압축하는 콤프레셔(미도시), 냉매를 분배순환시키는 솔레노이드밸브(미도시) 등이 구성되게 되나, 이러한 구성들은 주지의 기술이므로 더 상세한 설명은 필요하지 않다. 따라서 여기에서는 더 이상의 설명을 생략하기로 한다.Referring to the circulation process according to the cold air circulation structure, the cold air generated in the cooler 21 is circulated through the freezer compartment and the refrigerating compartment by the freezing compartment fan 22 and the refrigerating compartment fan 23, respectively. By this circulation, the freezing compartment and the refrigerating compartment are cooled. Of course, the main body 20 includes a compressor (not shown) for compressing the refrigerant at high temperature, a solenoid valve (not shown) for distributing and circulating the refrigerant, and the like. However, since these configurations are well-known techniques, a detailed description is not necessary. Therefore, further description will be omitted here.

상기 냉동실과 냉장실에서 순환된 냉기는 온도가 상승하게 되므로 이를 냉각기에 보내서 다시 냉각시킬 필요가 있게 되는데, 이를 위해 냉장실과 냉동실사이에 온기통로부(24)가 본체(20)의 하단에 형성되게 된다. 즉 냉동실과 냉장실을 분할하는 벽의 하단에 위치하게 된다.Since the cold air circulated in the freezer compartment and the refrigerating compartment increases in temperature, it is necessary to cool it again by sending it to a cooler. For this purpose, a warm passage part 24 is formed between the refrigerating compartment and the freezer compartment at the bottom of the main body 20. . That is, it is located at the bottom of the wall that divides the freezer compartment and the refrigerating compartment.

이러한 온기통로부(24)에 의하여 냉장실에서 온도상승된 냉기가 냉동실의 냉각기(21)로 유입되게 되어 재냉각이 이루어지게 된다. 그런데 보통 내동실의 냉각기로부터 자연대류에 의하여 냉각기의 냉기가 상기 통로부(24)를 통하여 냉장실로 흘러들어가게 되므로 냉장실의 과냉원인이 되기도 한다.The cold air that has risen in the temperature of the refrigerating compartment by the warm passage part 24 is introduced into the cooler 21 of the freezing compartment, thereby re-cooling. However, since the cool air of the cooler flows into the refrigerating chamber through the passage part 24 by natural convection from the cooler of the inner cavity, it is also a cause of overcooling of the refrigerating chamber.

이를 방지하기 위해 상기 온기통로부(24)에 체크밸브를 구성되게 되는데 이를 보여주는 도면이 도 3에 도시되어 있다. In order to prevent this, the check valve is configured in the warm passage part 24, which is illustrated in FIG. 3.

즉 도 3에는 제1체크밸브(30)와 제2체크밸브(31)가 냉동실과 냉장실을 분할하는 사절부(32)의 온기통로부(24)에 설치됨을 보여주고 있는 것이다.That is, FIG. 3 shows that the first check valve 30 and the second check valve 31 are installed in the warm passage part 24 of the trimmer 32 which divides the freezing compartment and the refrigerating compartment.

물론 상기 체크밸브(30, 31)가 작동되도록 하기 위해서 냉장실팬(23)과 연결시켜 냉장실팬(23)이 작동할 때는 체크밸브(30, 31)가 열어지도록 하고, 냉장실팬(23)이 정지될 경우에는 체크밸브(30, 31)가 닫히도록 하는 것이다.Of course, the check valves 30 and 31 are connected to the refrigerating chamber fan 23 so that the check valves 30 and 31 are opened when the refrigerating chamber fan 23 is operated, and the refrigerating chamber fan 23 is stopped. If so, the check valve (30, 31) is to be closed.

상기 예에서는 2개의 체크밸브가 구성되는 것을 보였으나 1개의 체크밸브로 구성되는 것도 가능하다. 물론 체크밸브에는 모터 등을 이용한 구동수단이 구비되게 된다. In the above example, it has been shown that two check valves are configured, but it is also possible to configure one check valve. Of course, the check valve is provided with a driving means using a motor or the like.

도 4는 본 발명에 따른 다른 실시예로서 플랩으로 구성된 과냉방지장치의 단면도를 보여주는 도면으로써, 상기 도 3에 기술된 구동수단이 구비된 체크밸브와 달리 공기의 순환에 의해서만 작동되도록 하는 특징이 있다.4 is a cross-sectional view of a supercooling preventing device composed of a flap as another embodiment according to the present invention, unlike the check valve provided with the driving means described in FIG. .

즉 플랩형식으로 개폐구를 구성함으로써 냉장실팬(23)이 정지중일때는 플랩(40)이 온기통로부(24)를 닫고 있는 것이다. 플랩(40)에는 자중이 있기 때문에 냉장실팬(23)이 미작동중일 때는 공기순환이 없게되므로 중력에 의해 플랩(40)이 아래로 향하게 되어 자동적으로 온기통로부(24)를 닫게 된다. 이와달리 냉장실에 공기순환이 있게되면 바람의 영향에 의하여 플랩(40)이 위로 올라가기 때문에 온기통로부(24)가 열리게 되어 냉장실의 냉기가 냉각기(21)로 유입될 수 있게된다.That is, the flap 40 closes the warm passage part 24 when the refrigerating compartment fan 23 is stopped by forming the opening / closing opening in a flap form. Since the flap 40 has its own weight, there is no air circulation when the refrigerating chamber fan 23 is not operating, so the flap 40 faces downward by gravity, thereby automatically closing the warm passage part 24. On the other hand, when there is an air circulation in the refrigerating compartment, the flap 40 is raised by the influence of the wind, so that the warm passage part 24 is opened so that the cool air in the refrigerating compartment may be introduced into the cooler 21.

이상, 본 발명에 대하여 첨부된 실시예와 도면을 가지고 상세히 기술하였으나, 본 발명은 특정 실시예에 한정되지는 않으며, 이 기술분야에 종사하고 있거나 통상의 지식을 습득하고 있는 자라면 본 발명의 내용을 벗어나지 않으면서도 수많은 변형과 수정이 가능함을 이해해야 할 것이다. 따라서, 본 발명의 보호범위는 첨부된 청구범위에 의거하여 정해짐이 바람직 할 것이다. As mentioned above, the present invention has been described in detail with reference to the accompanying embodiments and drawings, but the present invention is not limited to the specific embodiments, and those skilled in the art or acquiring general knowledge are provided with the contents of the present invention. It should be understood that numerous variations and modifications can be made without departing from the scope of the invention.
