본 고안은 냉장고에서 냉장실의 냉기 통로를 개폐시키는 냉장고의 냉장실용 온도 조절기에 관한 것이다.The present invention relates to a temperature controller for a refrigerator compartment for opening and closing the cold passage of the refrigerator compartment in the refrigerator.

종래의 냉장고용 온도 조절기는 절환캠에 팽창 영역과 폐쇄 영역을 연속으로 형성하고 캠축과 벨로우즈 사이에 설치되는 인장 스프링의 스프링정수가 벨로우즈의 팽창력보다 더크게 유지 되도록 하여 냉장 온도 영역내에서 벨로우즈의 팽창으로 온도 조절 효과를 얻게 하면서 냉장실의 폐쇄시에는 절환캠에 큰 단차를 주어 스프링의 인장력을 높임으로써 냉기 통로를 밀폐 시켜 왔으나 냉장실의 온도가 +10이상으로 올라가면 감열관의 가스압이 상승하여 스프링의 정수 보다 점차 커져 벨로우즈가 개폐판을 밀어 냉기 통로가 열리므로 냉기가 냉장실로 유입되어 온도 조절기의 기능을 다하기 못하였을 뿐아니라 냉장실을 냉동실로 사용하기 위하여 냉기통로가 완전 개방 상태를 유지 되게 하고자 하여도 인장 스프링의 인장력이 이완되어 완전 개방상태를 유지 시키지 못하는 결점이 있었다.Conventional refrigerator thermostats form an expansion zone and a closed zone in the switching cam continuously, and the spring constant of the tension spring installed between the camshaft and the bellows is kept larger than the expansion force of the bellows so that the expansion of the bellows in the refrigerating temperature zone When the refrigerating chamber is closed, it has closed the cold air passage by increasing the tension of the spring by increasing the tension of the spring when the refrigerating chamber is closed.However, when the temperature of the refrigerating chamber rises above +10, the gas pressure of the heat pipe rises, As the bellows becomes larger and larger, the cold air passage is opened by pushing the opening and closing plate, so the cold air flows into the fridge and not to function as a temperature controller, and to keep the cold passage fully open for use as the fridge. The tension of the tension spring is relaxed so that the fully open phase There was not a drawback not maintained.

본 고안은 종래의 이와같은 결점을 해결하기 위하여 개폐판으로 냉기통로를 개폐시켜 냉장실의 온도를 조절토록된 온도 조절기에 있어서 온도 조절기의 갑체 내부에 삽입홉과 지지부가 형성된 작동판을 설치하고 캠축상태에 결속홈이 형성된 고정구를 삽입 설치 시켜 냉기 통고의 완전개방 상태나 완전 밀폐 상태가 강제적으로 유지 되도록 하기 위한 목적으로 안출된 것이다.The present invention is to solve the drawbacks of the prior art in the temperature controller to open and close the cold air passage to the opening and closing plate to adjust the temperature of the refrigerating chamber in the body of the thermostat installed the operating plate formed with the insertion hop and the support portion in the cam shaft state By inserting a fastener formed with a binding groove in the cold air notification is to be devised for the purpose of maintaining a completely open state or a completely closed state.

이를 첨부 도면에 따라 상세히 설명하면 다음과 같다. 단일판으로 형성된 갑체(1)에 통공(5)(5')을 천공하고 삽착홈(3')을 갖는 캠축(3)의 회전에 따라 동시에 회전되는 절환캠(2)을 갑체(1)에 유설하며 캠축(3)에 결속홈(6)과 삽입공(6')을 갖는 고정구(4)를 삽입 시키고 삽착홈(3')에 핀(7)을 삽입 고정시키며 조절 나사(14')가 설치된 이동편(11)의 단부를 ""자형 지지부(10)를 갖는 작동판(8)에 형성된 통공(5″)에 삽입시켜 절환캠(2)의 상부에 연접지지 시키되 개폐판(13)에 연결된 연결대(12)의 하단부와 조절나사(14')사이에 스프링(14)을 고정설치하고 작동판(8)의 지지부(10) 형성된 홈부(9)로 스프링(14)의 하부를 삽입시켜 지지부(10)가 스프링(14)의 하부와 연결대(12)하부 사이에 삽입 지지시키며 캡(1')의 중앙부에 설치된 벨로우즈(15)를 감열관(16)과 연통 설치 하여서된 구조이다. 미설명 부호 17은 갑체(1)에 지지되는 연결대(12)의 괘지부 이고, 17')는 갑체에 지지되는 이동편(11)의 괘지부이며 18은 냉장고 기판에 형성된 냉기 통로이다.This will be described in detail with reference to the accompanying drawings. The switching cam 2 which is simultaneously rotated in accordance with the rotation of the cam shaft 3 having the insertion grooves 3 'is drilled through the through holes 5 and 5' in the body 1 formed of a single plate. Inserting the fastener 4 having the binding groove 6 and the insertion hole 6 'into the camshaft 3 and inserting and fixing the pin 7 into the insertion groove 3', the adjusting screw 14 ' The end of the installed moving piece 11 " Inserted into a through hole (5 ″) formed in the operating plate (8) having a shaped support 10 to be connected to the upper portion of the switching cam (2), but the lower end and the adjustment screw of the connecting table 12 connected to the opening and closing plate (13) The spring 14 is fixed between the 14 'and the lower portion of the spring 14 is inserted into the groove portion 9 formed in the supporting portion 10 of the operating plate 8 so that the supporting portion 10 is lower than the spring 14. And the bellows 15 installed at the center of the cap 1 'in communication with the thermal tube 16. The reference numeral 17 is used to support the body 1. The hook portion of the connecting table 12, 17 'is the hook portion of the movable piece 11 supported by the body and 18 is a cold air passage formed on the refrigerator substrate.

이상과 같이 구성된 본 고안은 갑체(1)의 양측에 괘지부(17')로 괘지된 이동편(11)의 단부가 절환캠(2)에 연접 지지되어 있어 절환캠(2)에 고정된 캠축(3)의 회전으로 스프링(14)에 탄지되어 있는 이동편(11)이 상, 하이동되고 이동편(11)의 상, 하 이동으로 스프링(14)에 연결된 개폐판(13)이 전, 후로 이동 되어 냉기통로(18)를 개폐시키므로 냉기의 유입 정도를 조절하여 냉장실의 온도를 조절하고 조절나사(14')로 연결대(12)와 이동편(11)사이로 설치된 스프링(14)의 정수를 조절토록함은 공지의 기능과 같으나 캠축(3)상에 결속홈(6)을 갖는 고정구(4)를 설치하고 갑체(1)내부에 홈부(9)와 지지부(10)가 형성된 작동판(8)을 유설하되 삽입공(5″)에 이동편(11)의 단부가 삽입 괘지 되어 절환캠(2)의 회전에 따라 이동편(11)과 함께 작동판(8)이 상, 하 이동되며 지지부(10)가 스프링(14)와 연결대(12) 하부 사이에 삽입 지지되어 있어 냉장실의 완전 밀폐시에 캠축(3)을 돌리면 고정구(4)는 공회전 되고 절환캠(2)의 회전으로 이동편(11)이 상승되고 따라서 작동판(8)이 상승되면서 스프링(14)의 하부를 들어 올리고 있으므로 연결대(12)로 연결 되어 냉기 통로(18)를 막고 있는 개폐판(13)의 밀폐 상태가 견고하게 유지 되도록한 것이며 냉기 통로(18)를 완전 개방 시켜 냉장실을 냉동실로 사용하기 위해서 캠축(3)을 돌리면 절환캠(2)이 회전되어 이동편(11)이 하향되고 따라서, 작동판(8)이 하향되어 연결대(12)의 하부를 누르므로 연결대(12)에 연결되어 냉기 통로(18)를 개방 시킴과 동시에 캠축(3)의 회전으로 이동편(11)이 하향되고 고정구(4)가 회전되어 이동편(11)의 단부를 결속홈(6)으로 삽입 시켜 제3도화같이 이동편(11)이 이동되지 못하게 상, 하로 고정 시킴으로 완전 개방 상태가 견고하게 유지 되도록한 것이다.According to the present invention configured as described above, an end portion of the moving piece 11 which is suspended by the hanging portion 17 'is supported by the switching cam 2 in contact with both sides of the body 1 and is fixed to the switching cam 2. The moving plate 11 supported by the spring 14 by the rotation of (3) is moved up and down, and the opening and closing plate 13 connected to the spring 14 by the up and down movement of the moving piece 11 is moved forward, Since it moves forward to open and close the cold air passage 18, the temperature of the refrigerating chamber is adjusted by adjusting the degree of inflow of cold air, and the constant of the spring 14 installed between the connecting rod 12 and the moving piece 11 by the adjustment screw 14 'is adjusted. The adjustment plate is the same as a known function, but the operation plate 8 is provided with a fastener 4 having a binding groove 6 on the camshaft 3 and a groove 9 and a support 10 formed inside the body 1. ) And the end of the moving piece 11 is inserted into the insertion hole 5 ″, and the operating plate 8 moves up and down together with the moving piece 11 according to the rotation of the switching cam 2, and the supporting portion 10 gas It is inserted and supported between the ring 14 and the lower part of the connecting rod 12. When the camshaft 3 is turned during the full close of the refrigerating chamber, the fixture 4 is idle and the moving piece 11 is raised by the rotation of the switching cam 2. Therefore, as the operating plate 8 is lifted, the lower portion of the spring 14 is lifted up, so that the sealing state of the opening and closing plate 13 which is connected to the connecting rod 12 and blocking the cold air passage 18 is maintained firmly. When the camshaft 3 is rotated to completely open the cold air passage 18 and use the refrigerating chamber as the freezing chamber, the switching cam 2 is rotated to move the moving piece 11 downward, and thus the operating plate 8 is downwardly connected to the connecting table ( 12, the lower part of the presser 12 is connected to the connecting table 12 to open the cold air passage 18, and at the same time the moving piece 11 is lowered by the rotation of the camshaft 3, and the fastener 4 is rotated to move the moving piece 11 Insert the end of the coupling into the binding groove (6) to prevent the moving piece (11) from moving as shown in FIG. Is one to be fixed sikimeuro fully opened state is firmly maintained at a.

이와같이 결속홈(6)을 갖는 고정구(4)를 캠룩(3)에 설치하여 이동편(11)을 결속 시키므로 스프링(14)에 관계없이 완전 개방 상태를 유지 시키며 홈부(9)와 지지부(10)를 갖는 작동판(8)을 갑체(1)내부에 설치하여 스프링(14)과 연결대(12)를 들어 올리므로 냉기 통로(18)의 완전 밀폐 상태를 견고하게 유지시켜 냉기가 유출됨이 없이 냉장고의 작동을 원활하게한 효과가 있는 것이다.In this way, the fastener 4 having the binding groove 6 is installed in the cam look 3 to bind the movable piece 11 to maintain the fully open state irrespective of the spring 14 and the groove 9 and the support 10. By installing the operating plate 8 having the inside of the upper body 1 to lift the spring 14 and the connecting rod 12, it is possible to maintain a tightly closed state of the cold air passage (18) so that the cold air does not leak out The effect is to smooth the operation.
