When controlling the temperature inside the room, sometimes the temperature control is not made precisely due to the deterioration of the control function, that is, the amount of cold air from the freezer is excessively inflowed to or below the required temperature, which is suitable for the stored food stored in the freezer. Because it can not maintain the drop in freshness to stored foods or even had a problem of causing a change in stored foods.

따라서 본 고안의 목적은 온도조절장치의 조절기능 저하시 냉장실의 온도 상태에 관계없이 냉동실로 부터 유입되는 냉기를 강제 차단시킬수 있도록 함으로써 상기 조절기능 저하시 발생되는 제반 문제점을 해소시킬수 있는 온도조절장치를 제공하는데 있으며, 상기의 목적을 실현하기 위하여 본 고안은 몸체의 내부 관통설치되는 캠에 의하여 설정된 온도상태에서 고내 온도를 감지하는 감온관과 이 감온관의 온도 감지상태에 따라 수축팽창하는 밸로우즈와 이 밸로우즈의 동작에 따라 냉기로릍 개폐시키는 댐퍼로 구성된 것에 있어서 상기 밸로우즈에 의하여 상하 구동하면서 상기 댐퍼를 개폐시키는 하부에 작동봉을 구비한 동작판과 상기 캠 회동시 연동하면서 상기 작동판을 상하 구동시키는 조절 작동판과 상기 동작판과 조절작동판을 연동시 구동을 정지시키는 강제 멈춤판으로 구성됨을 특징으로 한다.Accordingly, an object of the present invention is to provide a temperature control device capable of eliminating all problems caused by the decrease in the control function by forcibly blocking the cold air flowing from the freezer compartment regardless of the temperature of the refrigerating compartment when the control function of the temperature control device is lowered. In order to achieve the above object, the present invention provides a thermosensitive tube for detecting a temperature inside a high temperature in a temperature state set by a cam installed through an inner body of a body, and a bellows which contracts and expands according to a temperature sensing state of the thermosensitive tube; According to the operation of the bellows is configured as a damper to open and close the cold air by operating the operation plate provided with a working rod on the lower portion for opening and closing the damper by the bellows opening and closing the operating plate while interlocking the cam when rotating When interlocking the operation panel and the operation panel and the operation panel for driving up and down It is characterized by consisting of a forced stop plate for stopping the copper.

도면중 미설명 부호 11은 덮개(A)이고, 12는 덮개(B)이며, 16은 댐퍼스프링, 21은 프레온가스, C는 캠(8-2)이고 돌출부, 22는 냉장실의 냉기로이다.In the figure, reference numeral 11 is a cover A, 12 is a cover B, 16 is a damping spring, 21 is a freon gas, C is a cam 8-2, a protrusion, and 22 is a cold air in a refrigerating chamber.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

먼저 상기 몸체(1)에 상기 동작판(2), 조절작동판(3), 강제멈춤판(4), 캠부(8), 밸로우즈 보호판(18)을 각각 결합시키고 냉장실의 냉기로(22) 부위에 댐퍼스프링(16)으로 댐퍼(15)를 제1도 및 제2도에 도시한 바와같이 결합시킨 상태에서, 상기 캠부(8)의 다이알로그(14)를 어느 일방향으로 회전시키면 캠(8-2)은 상기 캠축(8-1)를 중심으로 회전되면서 상기 캠(8-2)상에 돌출된 돌출부(C)가 조절작동판(3)의 부위(a)와 접촉을 이루게되어 상기 조절작동판(3)은 상기 돌출부(C)에 의하여 상방으로 이동하게 되는 동시에 상기 조절작동판(3)과 강제멈춤판(4)으로 연동되는 동작판(2)도 함께 상방으로 강제 이동하게 되므로 동작판(2)의 하부에 형성된 작동부(9) 역시 상기 동작판(2)의 상방으로 이동된 만큼 들리게 되어 누루고 있던 댐퍼(15)를 풀어주게 된다.First, the operating plate (2), the adjusting operation plate (3), the forced stop plate (4), the cam portion (8), the bellows protection plate (18) are respectively coupled to the body (1), and the cold air in the refrigerating chamber (22) When the damper 15 is coupled to the site by the damper spring 16 as shown in Figs. 1 and 2, the cam 14 is rotated in any one direction so that the cam 8 -2) is rotated about the cam shaft (8-1) and the projection (C) protruding on the cam (8-2) is in contact with the portion (a) of the adjustment operating plate (3) the adjustment The operation plate 3 is moved upward by the protrusion C, and the operation plate 2 interlocked with the adjustment operation plate 3 and the forced stop plate 4 is also forced to move upward together. The operating part 9 formed at the lower part of the plate 2 is also lifted as far as the upper part of the operating plate 2 is released, thereby releasing the damper 15 that was pressed.

따라서 댐퍼(15)는 댐퍼스프링(16)의 인장력에 의하여 제2도의 점선으로 도시된 바와같이 냉기로(22)를 강제로 막아주게 되므로 상기 감온관(19)에서 감지된 온도가 상승하여 가스가 모세관(20)을 통해서 밸로우즈(17)를 팽창시켜도 동작판(2)이 상기 캠(8-2)의 돌출부(C)에 의하여 강제로 상방으로 밀고 있으므로, 동작판(2)은 하방으로 복귀가 되지 않게 된다.Therefore, the damper 15 is forcibly blocked by the cold air 22 as shown by the dotted line in FIG. 2 by the tensile force of the damper spring 16, so that the temperature detected by the temperature reduction tube 19 rises, Even when the bellows 17 is expanded through the capillary tube 20, the operation plate 2 is pushed upward by the protrusion C of the cam 8-2, so that the operation plate 2 returns downward. Will not be

그러므로 상기 댐퍼(15)는 냉기로(22)를 막고 있는 상태를 계속 유지하고 있기 때문에 냉기로(22)의 냉기를 강제적으로 차단하는 상태가 된다.Therefore, the damper 15 is in a state of forcibly blocking the cold air of the cold air 22 because the damper 15 is kept in the state of blocking the cold air 22.

한편 상기 캠부(8)의 다이알로그(14)를 원상태로 복귀시키면 상방으로 올라가 있던 조절작동판(3)이 이 하방으로 원위치 되면서 이와 강제멈춤판(4)으로 연동되는 동작판(2) 역시 하방으로 내려오게 되므로 상기 동작판(2)의 하부에 형성된 작동봉(9) 역시 하방으로 내려오면서 댐퍼(15)를 눌러주게 되므로 제2도에 도시한 바와같이 댐퍼스프링(16)의 인장력으로 냉기로(22)를 막고 있던 댐퍼(15)는 댐퍼스프링(16)의 인장력을 극복하게 되어 냉기로(22)는 열리게 된다.On the other hand, when the dialog 14 of the cam part 8 is returned to its original state, the operating plate 2 which is interlocked with the forced stop plate 4 also moves downward while the adjustment operation plate 3 that has been raised upward is moved downward. Since the operating rod (9) formed in the lower portion of the operating plate (2) is also pushed down and presses the damper (15) downward, as shown in FIG. 2, the tension of the damper spring (16) is reduced to cold. The damper 15 blocking the 22 overcomes the tensile force of the damper spring 16 so that the cold air 22 is opened.

그러므로 상기 감온관(19)에서 감지된 온도 상태에 따라 상기 밸로우즈(17)는 수축 또는 팽창하면서 댐퍼(15)로 냉기로(22) 개폐하게 된다.Therefore, the bellows 17 is opened or closed by the cooler 22 with the damper 15 while contracting or expanding according to the temperature state sensed by the temperature sensing tube 19.

이상에서 설명한 바와같이 본 고안은 냉장실의 고내 온도를 조절함에 있어 냉기를 강제 차단시킬수 있도록 함으로써 간혹 자동온도조절장치가 기능 저하로 인하여 온도조절이 정확히 이루어지지 않을 때 발생되는 제반문제점을 해소할 수 있는 이점을 제공하게 되는 것이다.As described above, the present invention allows the cold air to be forcibly shut off in the control of the internal temperature of the refrigerating compartment, which can sometimes solve the problems caused when the thermostat is not precisely controlled due to a decrease in function. This will provide an advantage.
