Description

냉장고의 냉기토출 제어장치Cold air discharge controller

본 발명은 냉장고에 설치되어 사용되는 냉기토출 제어장치에 관한 것으로, 더욱 상세하게는, 고내로 토출되는 냉기를 분산하여 토출시키는 한편, 고내의 어느 한 부분이 과냉되는 것을 방지토록 한 냉장고의 냉기토출 제어장치에 관한 것이다.The present invention relates to a cold air discharge control device installed and used in the refrigerator, and more particularly, to the cold air discharge of the refrigerator to disperse and discharge the cold air discharged into the refrigerator, and to prevent any part of the inside of the refrigerator from being overcooled. It relates to a control device.

일반적으로 냉장고 고내(냉장실 및 냉동실)에는 증발기와 팬(fan)이 설치된다. 증발기는 압축기가 작동되어 증발기의 내부에 있는 액상의 냉매가 증발할 때 냉매의 열교환으로 주변 공기를 냉각시키고, 팬은 증발기 주위에서 냉각된 공기를 고내로 강제순환시키기 위한 것이다. 따라서 고내 온도는 그 압축기와 팬을 그 온도 변화에 따라 적절히 작동시키므로써 유지된다.In general, an evaporator and a fan are installed in a refrigerator refrigerator (freezer compartment and freezer compartment). The evaporator cools the surrounding air by heat exchange of the refrigerant when the liquid refrigerant inside the evaporator evaporates while the compressor is operated, and the fan is forcibly circulating the cooled air around the evaporator. Thus, the internal temperature is maintained by operating the compressor and fan properly according to the temperature change.

이와 같은 냉장고의 구조와 고내의 냉기 순환계통을 도 1을 참조하여 설명하면, 냉장고 본체(1)는 중간의 격벽(4)에 의해 냉동실(2)과 냉장실(3)로 구분되어 있고, 그 각각에는 도어(3)(6)가 개폐가능하게 설치된다. 냉장실(5)은 식품을 올려놓기 위해 설치되는 복수개의 선반(9)들에 의해 다층으로 구분되는데, 그 최하측에는 야채실(10)이 구획되어 있다.The structure of the refrigerator and the cold air circulation system in the refrigerator will be described with reference to FIG. 1. The refrigerator body 1 is divided into a freezer compartment 2 and a refrigerator compartment 3 by an intermediate partition 4, respectively. The doors 3 and 6 are installed to be openable and openable. The refrigerating chamber 5 is divided into multiple layers by a plurality of shelves 9 provided for placing food, and the vegetable chamber 10 is partitioned at the lowermost side.

그리고, 냉동실(2)의 후면벽 내에는 냉매관(도시는 생략함)을 통해 유입된 액체 냉매를 낮은 온도에서 증발시키면서 냉장고 내부의 열을 흡수하여 냉각시키는 증발기(7)가 설치되어 있다. 또 상기 증발기(7)의 상부에는, 그 냉각된 공기를 냉동실(2) 및 냉장실(5)로 강제로 송풍시켜 냉기를 순환시키기 위한 냉각팬(8)이 설치되어 있다.In the rear wall of the freezer compartment 2, an evaporator 7 is provided to absorb and cool the heat inside the refrigerator while evaporating the liquid refrigerant introduced through the refrigerant pipe (not shown) at a low temperature. In addition, a cooling fan 8 is provided above the evaporator 7 to forcibly blow the cooled air into the freezing chamber 2 and the refrigerating chamber 5 to circulate cold air.

또한, 냉장실(5)의 후벽에는 냉기의 통로인 냉기덕트(11)가 마련되어 있고, 그 냉기덕트(11)의 전방에는 냉기덕트(11)내로 유입된 냉기를 냉장실(5) 내부로 분산하여 토출시키기 위한 그릴형의 냉기 토출공(12)이 마련되어 있다.In the rear wall of the refrigerating chamber 5, a cold air duct 11, which is a passage for cold air, is provided, and in front of the cold air duct 11, cold air introduced into the cold air duct 11 is dispersed into the refrigerating chamber 5 and discharged. The grill-type cold air discharge hole 12 is provided.

그리고, 상기 냉기덕트(11)에는, 냉기덕트(11)와 대략 동일한 높이로 되어, 냉기를 고내에 분배시키기 위해 회전되는 회전날개(13)가 설치됨에 따라, 냉장고의 작동시 회전날개(13)가 회전되므로써, 도면에 표시된 화살표와 같이 각층에서 여러방향으로 냉기를 토출시키게 된다.In addition, the cold air duct 11 has the same height as the cold air duct 11 and is provided with a rotary vane 13 that is rotated to distribute cold air in the refrigerator. By rotating, cold air is discharged in various directions in each layer as shown by the arrow shown in the drawing.

또한, 상기 냉장고 본체(1)하단 일측의 기계실(14)에는, 저온, 저압의 가스상태의 냉매를 압축시켜 고온, 고압의 가스 상태로 만들어 주는 압축기(15)가 설치된다.In addition, a compressor 15 for compressing a low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas state is installed in the machine room 14 on the lower side of the refrigerator main body 1.

상기와 같이 설치되어, 이들이 냉매관에 의해 상호 연결되므로써 하나의 냉동 사이클을 수행하게 되며, 이를 통해 원하는 냉동 및 냉장효과를 얻게 된다.Installed as described above, they are interconnected by the refrigerant pipe to perform a single refrigeration cycle, thereby obtaining the desired refrigeration and refrigeration effect.

상기와 같이 구성되는 냉장고의 작동을 살펴보면 다음과 같다. 냉장고 도어(3)(6)의 잦은 개폐와 기타 이유로 인해 고내 온도가 상승되게 되면, 증발기(7)에서 주위와의 열교환으로 발생된 냉기는 냉각팬(8)의 작동에 의해 고내로 공급되거나, 하향하여 냉기덕트(11)내로 흐르게 된다. 상기와 같은 작동으로, 냉기가 냉기덕트(11)내로 유입되면, 냉기덕트(11)내부에 형성되는 회전날개(13)가 회전하게 되고, 냉기는 그 회전날개(13) 전방의 냉기덕트(11)에 형성된 냉기 토출공(12)을 통해 고내로 토출되게 되며, 그중 일부는 계속 하향하여 최하측에 구획 형성된 야채실(10)에 공급되게 된다.Looking at the operation of the refrigerator configured as described above are as follows. When the internal temperature of the refrigerator is increased due to frequent opening and closing of the refrigerator doors 3 and 6 and other reasons, the cold air generated by heat exchange with the surroundings in the evaporator 7 is supplied into the interior by the operation of the cooling fan 8, It flows downward into the cold air duct (11). By the operation as described above, when cold air flows into the cold air duct 11, the rotary blade 13 formed in the cold air duct 11 is rotated, the cold air duct 11 in front of the rotary wing (13). The air is discharged into the refrigerator through the cold air discharge hole 12 formed in the), and some of them are continued downward and supplied to the vegetable chamber 10 partitioned at the lowermost side.

또, 상기와 같이 고내에 냉기가 토출되어 고내온도가 적정온도에 이르게 되면, 고내의 온도 조절을 위해 고내로 토출되는 냉기 토출공(12)을 폐쇄하게 된다.In addition, when the cold air is discharged into the refrigerator as described above and the temperature inside the refrigerator reaches an appropriate temperature, the cold air discharge hole 12 discharged into the refrigerator is closed to control the temperature in the refrigerator.

그러나, 종래의 냉장고에 의하면, 고내의 온도 조절을 위해 고내로 토출되는 냉기 토출공(12)을 폐쇄하였을 때, 야채실(10)로 전달되는 냉기흐름을 제어할만한 별다른 수단이 마련되어있지 않으므로써, 야채실(10)로 전달되는 냉기흐름을 제어할 수가 없었다. 이와 같이, 야채실(10)로 공급되는 냉기의 량을 제어할 수 없게 되므로써, 야채실(10)에는 항상 냉기가 공급되고, 이로 인해 과냉 현상이 발생하였다. 이런 이유로, 그 야채실(10)에 보관되는 식품의 손상이 종종 발생되게 되는등의 제품의 신뢰성을 저하시키게 되는 문제점이 발생하였다.However, according to the conventional refrigerator, when the cold air discharge hole 12 discharged into the refrigerator is closed for temperature control in the refrigerator, there is no other means for controlling the flow of cold air delivered to the vegetable chamber 10. Could not control the cold air flow to (10). In this way, since the amount of cold air supplied to the vegetable chamber 10 cannot be controlled, cold air is always supplied to the vegetable chamber 10, which causes a supercooling phenomenon. For this reason, there arises a problem that the reliability of the product is lowered such that food damage often stored in the vegetable chamber 10 occurs.

본 발명은 상기한 문제점을 해결하기 위한 것으로, 고내 냉기토출이 차단되었을 때, 야채실로 전달되는 냉기흐름을 제어할 수 있도록 하므로써, 야채실이 과냉되는 것을 방지하기 위한 냉장고의 냉기토출 제어장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, and when the cold air discharge in the refrigerator is blocked, it is possible to control the cold air flow delivered to the vegetable room, to provide a cold air discharge control apparatus for preventing the vegetable room from being overcooled. The purpose is.

For reference, the drawings referred to below will be described with the same reference numerals for the same parts as in the prior art for convenience of description.

본 발명에 따른 냉장고의 냉기토출 제어장치는 도 2에 도시한 바와 같이, 냉장실(5)후벽의 냉기덕트(11)상에 설치되어 고내에 냉기를 토출시키기 위한 복수개의 토출그릴(21)을 갖는 냉기토출 제어부(20)와, 상기 냉기토출 제어부(20)의 토출그릴(21) 일단과 결합되어, 그 토출그릴(21)을 폐쇄 및 개방시키기 위한 안내부재(22)와, 상기 안내부재(22)와 결합되어 그 안내부재(22)를 승강시키기 위해 구동되는 구동수단으로 이루어진다.As shown in FIG. 2, the cold air discharge control apparatus of the refrigerator according to the present invention is provided on the cold air duct 11 on the rear wall of the refrigerating chamber 5 and has a plurality of discharge grills 21 for discharging cold air in the refrigerator. It is coupled to the cold air discharge control unit 20, one end of the discharge grill 21 of the cold air discharge control unit 20, a guide member 22 for closing and opening the discharge grill 21, and the guide member 22 It is composed of a driving means that is coupled to and driven to lift the guide member 22.

상기 안내부재(22)는, 고내로 토출되는 냉기를 제어하기 위한 종방향 안내부재(22a)와, 야채실(10)로 유입되는 냉기를 제어하기 위한 횡방향 안내부재(22b)로 구분된다. 또, 상기 종방향 안내부재(22a)의 하측과, 횡방향 안내부재(22b)의 일측에는 각각 래칫(23a)(23b)이 형성되어 상기 구동수단과 결합된다. 또한, 각각의 안내부재(22a)(22b)는 상기 냉기토출 제어부(20)의 토출그릴(21)과 결합되어 냉기의 흐름을 제어하게 된다.The guide member 22 is divided into a longitudinal guide member 22a for controlling cold air discharged into the refrigerator and a lateral guide member 22b for controlling cold air introduced into the vegetable chamber 10. In addition, ratchetes 23a and 23b are formed on the lower side of the longitudinal guide member 22a and the one side of the transverse guide member 22b, respectively, and are coupled to the driving means. In addition, each of the guide members 22a and 22b is combined with the discharge grill 21 of the cold air discharge control unit 20 to control the flow of cold air.

상기 구동수단은, 상기 안내부재(22a)(22b)의 래칫(23a)(23b)과 결합되는 피니언(24)과, 그 피니언(24)을 구동시키기 위한 모터(25)로 구성된다.The drive means comprises a pinion 24 engaged with the ratchet 23a and 23b of the guide members 22a and 22b and a motor 25 for driving the pinion 24.

상기와 같이 구성된 본 발명에 따른 냉장고의 냉기토출 제어장치에 의하면, 증발기(7)에서 주위와의 열교환으로 발생된 냉기는 냉각팬(8)의 작동에 의해 고내로 공급되거나, 하향하여 냉기덕트(11)내로 유입되게 된다. 상기와 같은 작동으로, 냉기가 냉기덕트(11)내로 유입되면, 유입된 냉기는 냉기 토출공(12)을 통해 고내로 토출되게 되며, 그중 일부는 계속 하향하여 최하측에 구획 형성된 야채실(10)에 공급되게 된다. 상기와 같은 작동에 의해 고내온도가 하강하여 적정온도에 이르게 되면, 냉기 토출공(12)을 폐쇄하여 고내온도를 적정상태로 유지하게 된다. 이때, 도 3에 도시한 바와 같이, 상기 모터(25)가 일방향으로 작동하게 되고, 이에 따라, 그 모터(25)에 결합된 피니언(24)또한 회전하게 된다. 상기 모터(25)의 구동에 의해 상기 피니언(24)이 회전하게 되면, 그 피니언(24)에 치합된 종방향 안내부재(22a) 및 횡방향 안내부재(22b)의 래칫(23a)(23b)에도 모터(25)의 회전력이 전달되게 된다. 이와 같이, 종방향 안내부재(22a) 및 횡방향 안내부재(22b)에 형성되는 래칫(23a)(23b)에 모터(25)의 회전력이 전달되게 되면, 종방향 안내부재(22a)가 하강하게 되고, 이와 동시에 횡방향 안내부재(22b) 또한 타측으로 이동되게 된다.According to the cold air discharge control apparatus of the refrigerator according to the present invention configured as described above, the cold air generated by the heat exchange with the surroundings in the evaporator (7) is supplied to the interior by the operation of the cooling fan (8), or downward cold air duct ( 11) It will flow into. By the operation as described above, when the cold air is introduced into the cold air duct 11, the introduced cold air is discharged into the high through the cold air discharge hole 12, some of them continue to be downward downward partitioned vegetable chamber 10 To be supplied. When the internal temperature of the refrigerator is lowered by the operation as described above to reach the proper temperature, the cold air discharge hole 12 is closed to maintain the internal temperature at a proper state. At this time, as shown in FIG. 3, the motor 25 operates in one direction, and thus, the pinion 24 coupled to the motor 25 also rotates. When the pinion 24 is rotated by driving the motor 25, the ratchet 23a and 23b of the longitudinal guide member 22a and the lateral guide member 22b engaged with the pinion 24 are rotated. The rotational force of the motor 25 is also transmitted. Thus, when the rotational force of the motor 25 is transmitted to the ratchet 23a, 23b formed in the longitudinal guide member 22a and the transverse guide member 22b, the longitudinal guide member 22a is lowered. At the same time, the transverse guide member 22b is also moved to the other side.

상기와 같이, 종방향 안내부재(22a)가 하강하게 되면, 그 안내부재(22a)에 결합된 토출그릴(21)에 의해 냉기 토출공(12)이 폐쇄되고, 이를 통해 고내로 토출되는 냉기의 량을 조절할 수 있다. 이와 동시에 횡방향 안내부재(22b)가 타측으로 이동하게 되면, 그 안내부재(22b)에 결합된 토출그릴(21)이 야채실(10)로 유입되는 냉기 흐름을 차단하게 된다. 이와 같이 되어, 고내 냉기토출이 차단되었을 때, 야채실(10)로 유입되는 냉기 흐름도 제어할 수 있어서, 야채실(10)에 저장되는 식품이 과냉되는 것을 방지할 수 있는 것이다.As described above, when the longitudinal guide member 22a is lowered, the cold air discharge hole 12 is closed by the discharge grill 21 coupled to the guide member 22a, and thus the cold air discharged into the refrigerator is discharged. The amount can be adjusted. At the same time, when the lateral guide member 22b moves to the other side, the discharge grill 21 coupled to the guide member 22b blocks the flow of cold air flowing into the vegetable chamber 10. In this way, when the cold air discharge in the refrigerator is blocked, the flow chart of the cold air flowing into the vegetable chamber 10 can be controlled to prevent the food stored in the vegetable chamber 10 from being overcooled.
