본 발명은 냉장고의 냉기조절장치에 관한 것으로서, 더욱 상세하게는 냉장고에 냉장실의 온도변화에 따라 일정한 상태로 냉기량을 조절할 있도록 한 것이다.The present invention relates to a cold air conditioner of a refrigerator, and more particularly, to adjust the amount of cold air in a constant state in accordance with the temperature change of the refrigerating compartment in the refrigerator.
일반적으로 냉장고는 음식물을 냉동보관하는 냉동실(1)과 냉장보관하는 냉장실(2)로 크게 구성되어 있는데, 상기 냉장실에는 냉장실(2)의 온도에 따라 냉기공급이 선택적으로 행해지도록 하는 냉기조절장치를 갖추고 있다.In general, the refrigerator is largely composed of a freezer compartment (1) for freezing and storing food and a refrigerating compartment (2) for storing the food. The refrigerator has a cold air control device for selectively supplying cold air according to the temperature of the refrigerating compartment (2). Equipped.
종래에는 첨부도면 제1도 내지 제2도에 나타낸 바와 같이, 냉장실(2)내의 냉기공급관(3a)과 연결된 콘트롤박스(8a)의 조절놉(10a)으로 일정온도를 셋팅시켜 놓으면 상기 냉장실(2)내의 온도가 셋팅시켜 놓은 조건에 맞게 일정상태를 유지하는데, 이와 같은 상태에서 냉장실(2) 내부의 온도가 상승하게 되면 상기 콘트롤박스(8a)의 후방에 연결된 온도조절기(24)가 온도변화를 일으키므로 상기 온도조절기(24)내에 압력이 가해지게 된다.Conventionally, as shown in FIGS. 1 to 2, when a predetermined temperature is set by the adjusting knob 10a of the control box 8a connected to the cold air supply pipe 3a in the refrigerating compartment 2, the refrigerating compartment 2 In this state, when the temperature inside the refrigerator compartment 2 rises, the temperature controller 24 connected to the rear of the control box 8a can change the temperature. As a result, pressure is applied to the temperature controller 24.
이 압력은 온도조절기(24) 및 냉동실(1)과 연통되어 있는 냉기공급관(3a) 끝단의 댐퍼판(6a) 사이에 연결된 판스프링(7a)을 밀어내는 힘으로 작용하여 판스프링(7a)이 이동하게 되므로 상기 댐퍼판(6a)에 의해 냉기공급관(3a)이 차단된 상태에서 그 사이에 틈새가 벌어져 이 틈새로 냉기가 유입되고 이 유입된 냉기는 계속해서 콘트롤박스(8a) 하단의 출구공(25)을 통해 토출되어 냉장실(2)로 공급된다.This pressure acts as a force to push the leaf spring 7a connected between the temperature controller 24 and the damper plate 6a at the end of the cold air supply pipe 3a in communication with the freezing chamber 1 so that the leaf spring 7a Since the cold air supply pipe 3a is blocked by the damper plate 6a, a gap is formed therebetween so that cold air flows into this gap, and the cold air continues to flow out of the bottom of the control box 8a. Discharged through 25 is supplied to the refrigerating chamber 2.
그 후, 어느 정도의 냉기가 냉장실(2)에 공급되어 상기 냉장실(2)의 온도가 내려가게 되면 콘트롤박스(8a) 후방에 연결된 가스관(26)내의 기체부피가 줄어들어서 압력이 감소되므로 인해 온도조절기(24)와 댐퍼판(6a) 사이에 연결된 판스프링(7a)이 원위치하게 되고 이에 따라 상기 댐퍼판(6a)이 냉기공급관(3a)의 통로를 막아주므로 더이상 냉장실(2)내로 냉기가 공급되지 않는다.Afterwards, when a certain amount of cold air is supplied to the refrigerating compartment 2 and the temperature of the refrigerating compartment 2 is lowered, the volume of gas in the gas pipe 26 connected to the rear of the control box 8a is reduced and the pressure is reduced. The leaf spring 7a connected between the regulator 24 and the damper plate 6a is returned to its original position, and thus the damper plate 6a blocks the passage of the cold air supply pipe 3a, so that cold air is no longer supplied into the refrigerating chamber 2. It doesn't work.
그러나, 이와 같은 종래 냉장고의 콘트롤박스(8a) 후방에 연결된 가스관(26)내에는 가스가 충진되어 있으므로 압력에 의해 벨로우즈(도시는 생략함)가 반복운동을 수행함에 따라 기기를 장기간 사용하다보면 상기 벨로우즈가 노후 및 피로강도에 의해 파손되므로써 가스가 누출되어 제기능을 효율적으로 수행하지 못하게 되는 등의 문제점이 있었다.However, since the gas is filled in the gas pipe 26 connected to the rear of the control box 8a of the conventional refrigerator, the bellows (not shown) is repeatedly operated by the pressure. As the bellows is damaged by aging and fatigue strength, there is a problem such that the gas leaks, and thus the bellows cannot be efficiently performed.
본 발명은 냉장고에 냉장실의 온도를 사용자가 일정온도로 셋팅시킨 상태에서 상기 냉장실에 온도변화가 일어나게 되면 즉각 대응하여 자동으로 냉장실 내의 냉기량을 조절할 수 있도록 함에 따라 보다 성능이 우수한 냉장고를 제공하고자 하는데 그 목적이 있다.The present invention is to provide a refrigerator having a better performance by allowing the user to automatically adjust the amount of cold air in the refrigerator compartment when the temperature change occurs in the refrigerator compartment while the user sets the temperature of the refrigerator compartment to a certain temperature.

이와 같이 구성된 본 발명은 제3도 및 제4도에 나타낸 바와 같이, 냉장고의 냉장고의 냉장실(2)내에 냉기를 공급하는 냉기공급관(3)과 연결된 콘트롤박스(8)의 조절놉(10)으로 표준, 약, 강, 중의 모드중 어느 한 모드를 선택하여 조절놉(10)을 회전시킴에 따라 회전축(9)에 고정된 조절부재(11)가 콘트롤박스(8)내에서 회전하는데, 이때 조절부재(11)에 고정된 제어봉(12)의 끝단이 구동축(15)에 일단이 고정된 상태로 감겨져 있는 태엽스프링(17)의 타단과 접촉되어 있으므로 상기 태엽스프링(17)은 어느 한 방향으로 감겨져 일정상태로 되고 이에 따라 냉장실(2)내의 온도가 설정된 일정온도로 유지되는 제4도의 (나)와 같은 상태가 된다.The present invention configured as described above has a control knob 10 of the control box 8 connected to the cold air supply pipe 3 for supplying cold air into the refrigerating chamber 2 of the refrigerator as shown in FIGS. 3 and 4. As the control knob 10 is rotated by selecting any one of the standard, weak, strong, and among the modes, the adjusting member 11 fixed to the rotating shaft 9 rotates in the control box 8, wherein the adjusting Since the end of the control rod 12 fixed to the member 11 is in contact with the other end of the spring spring 17, one end of which is wound around the drive shaft 15, the spring spring 17 is wound in one direction. It becomes a fixed state and, as a result, it becomes a state like (b) of FIG. 4 in which the temperature in the refrigerating chamber 2 is maintained at a predetermined fixed temperature.
이와 같은 상태에서 냉장실(2) 내부의 온도가 상승하게 되면, 온도변화에 따라 변형되는 형상기억합금으로 된 태엽스프링(17)에 변형이 발생하게 되는데, 상기 태엽스프링(17)은 그 일단이 구동축(15)에 고정되어 있으므로 태엽스프링(17)의 변형에 따라 구동축(15)이 회전을 하게 되고, 이때 상기 구동축에 고정된 제1기어(16)가 함께 회전하므로 제2기어(20)는 제1기어의 회전력을 받아 종동축(19)을 중심으로 회전하게 된다.In this state, when the temperature inside the refrigerating chamber 2 rises, deformation occurs in the spring of the shape memory alloy 17 which is deformed according to the temperature change. The spring of the spring 17 has one end thereof. Since the driving shaft 15 is rotated in accordance with the deformation of the spring spring 17, the first gear 16 fixed to the driving shaft rotates together. It is rotated about the driven shaft 19 by the rotational force of one gear.
이와 같이 하여 제2기어(20)가 회전하면 캠(21)전방의 지지부재(5)에 왕복 직선이동을 할 수 있도록 설치된 작동봉(22)의 일단이 상기 캠(21)에 형성된 경사면(S)과 접속되어 있으므로 작동봉(22)은 캠(21)의 경사면(S) 각도만큼 전진하여 지지부재(5)에 고정된 판스프링(7)을 밀어주게 되고, 이에 따라 상기 지지부재(5)의 냉기공(4)을 폐쇄하고 있던 댐퍼판(6)이 제4도의 (가)와 같이 개방되므로 냉장실(2)내로 냉기가 유입된다.As such, when the second gear 20 rotates, one end of the operating rod 22 installed to the reciprocating linear movement to the support member 5 in front of the cam 21 is formed on the inclined surface S of the cam 21. Since the operating rod 22 is advanced by the inclined surface (S) angle of the cam 21 to push the leaf spring (7) fixed to the support member (5), thereby supporting the support member (5) Since the damper plate 6 which has closed the cold air hole 4 of Fig. 4 is opened as shown in FIG. 4A, cold air flows into the refrigerating chamber 2.
한편 냉장실(2)내로 냉기가 유입되어 냉장실(2)의 내부온도가 최초 조절놉(10)으로 셋팅시킨 설정온도까지 하강하게 되면, 태엽스프링(17)이 형상기억합금의 특성으로 인해 최초 셋팅된 상태로 복원되고, 전술한 바와 같은 작동의 역순에 의해 댐퍼판(6)이 제4도의 (가)와 같은 상태에서 제4도의 (나)와 같은 상태로 닫히면서 냉기공(4)이 폐쇄되므로 냉장실(2)의 온도변화에 즉각대응하여 신속하게 냉장실(2)의 냉기를 자동으로 조절할 수 있게 된다.On the other hand, when cold air flows into the refrigerating compartment 2 and the internal temperature of the refrigerating compartment 2 drops to the set temperature set by the initial adjustment knob 10, the spring spring 17 is initially set due to the shape memory alloy. Is restored to the state, and the cold air hole 4 is closed while the damper plate 6 is closed in the same state as in (a) of FIG. It is possible to automatically adjust the cold air of the refrigerating compartment 2 quickly in response to the temperature change of the refrigerating compartment 2.
또한, 조절부재(11)의 후방에는 콘트롤박스(8)에 형성된 복수개의 걸림홈(13)에 삽입되도록 고정돌기(14)가 형성되어 있어 조절놉(10)을 회전시켜 표준, 강, 중, 약 모드 중 어느 한 모드로 냉기를 조절할 때 상기 조절부재(11)가 조절된 상태에서 유동됨이 없게 된다.In addition, the fixing member 14 is formed at the rear of the adjusting member 11 so as to be inserted into the plurality of locking grooves 13 formed in the control box 8 so that the adjustment knob 10 is rotated so that the standard, steel, medium, When the cold air is adjusted to any one of the weak modes, the adjusting member 11 is not flowed in the adjusted state.
이상에서 설명된 바와 같이 본 발명은 냉장고에 냉장실(2)의 온도를 사용자가 조절놉(10)을 회전시켜 일정온도로 셋팅시킨 상태에서 냉장실(2)내의 온도가 변화하면 즉각 대응하여 자동으로 냉장실(2)내의 냉기량을 조절하여 주므로 제품의 효율성 및 신뢰성이 향상되는 효과가 있어 매우 유용한 발명이다.As described above, in the present invention, when the temperature of the refrigerating compartment 2 changes in a state in which the temperature of the refrigerating compartment 2 is set to a predetermined temperature by rotating the control knob 10 in the refrigerator, the refrigerating compartment is automatically responded immediately. (2) It is a very useful invention because it controls the amount of cold air in the product, which improves the efficiency and reliability of the product.
