본 고안은 온도의 변화에 따른 가스(Gss)의 체적팽창을 이용하여 샷터를 개폐시켜 냉기 유입을 제어하는 강제 순환식 냉동 냉장고의 냉장실 온도 조절기에 있어서 냉장실의 폐쇄에 있어, 온도 조절 절환 놉의 간단한 셋팅에 의해 어떠한 온도에서도 샷터가 개방되지 않는 기능을 갖도록 함으로서 냉기 유입을 차단시킬 수 있는 온도 조절기에 관한 것이다.The present invention is to close the refrigerating compartment in the refrigerating compartment temperature controller of the forced circulation refrigerator which controls the flow of cold air by opening and closing the shoter by using the volume expansion of the gas (Gss) according to the change of temperature, the simple adjustment of the temperature control knob The present invention relates to a temperature controller capable of blocking the inflow of cold air by having a function that the shoter does not open at any temperature by setting.
종래의 냉장실 내에 설치되는 온도 조절기의 뎀퍼는 온도 조절 놉의 조절에 따라 냉장 온도 범위내에서만 최고 및 최저로의 온도조정이 되어 사용중 냉장실의 온도가 10℃-30℃ 정도로 상승되면 온도 감지부에 의해 벨로우즈가 팽창되며 샷터레버를 밀어 샷터레버에 연결된 샷터가 증발기로부터 냉장실로 유입되는 유통로를 완전히 개방시키어 냉기가 유통되게 하였던 것이며, 냉장실을 폐쇄기키기 위하여 조절놉을 폐쇄측으로 회전시키면 조절놉에 설치된 폐쇄캠에 의해 샷터레버를 강제로 밀게하여 샷터가 냉기의 유통로를 차단시키게 하고 있으나 조절놉을 회전시킴에 있어 조절놉의 폐쇄캠과 샷터레버의 간격이 맞지 않거나 샷터레버를 지지하여 주는 인장스프링이 이완되었을 때에는 폐쇄캠에 의해 샷터 레버의 눌름동작에 무리한 힘이 전달될 염려가 있었던것으로 조절놉으로 샷터에 정확한 전달동작을 기대하기 어려웠던 것이다.The damper of the temperature controller installed in the conventional refrigerator compartment is adjusted to the maximum and minimum temperature only within the refrigerator temperature range according to the adjustment of the temperature control knob. The bellows were expanded and the shot lever connected to the shot lever was pushed to open the flow path from the evaporator to the refrigerating chamber so that the cold air flowed. The shot lever is pushed by the cam forcibly to block the flow path of the cold air, but when rotating the adjusting knob, the gap between the closing cam of the adjusting knob and the shot lever is not matched or the tension spring supporting the shot lever is supported. When it is relaxed, excessive force is transmitted to the pressing action of the shot lever by the closing cam. It was difficult to expect accurate delivery to the shoter with the adjustment knob.
본 고안은 상기의 재결점을 해결하기 위하여 가스의 체적팽창을 이용하여 샷터를 개폐시키는 공지한 온도조절기의 절환 놉에 설치되는 절환 캠에 통상의 팽창 영역 이외에 냉장영역의 반경을 보다 반경이 큰 폐쇄영역을 연속하여 형성하고, 캠 레버와 샷터레버 사이에 인장 스프링을 설치하는 것과 병행하여 캠레버와 샷터 레버사이에 강제로 냉기 유입을 차단시킬 수 있는 강선을 설치하여서 인장스프링을 보호하며 냉기 유입을 강제로 차단시킬 수 있게 한 것이다.The present invention is to close the radius of the refrigerating area having a larger radius in addition to the normal expansion area in the switching cam installed in the switching knob of the known temperature controller to open and close the shot using the volume expansion of the gas to solve the above-mentioned defects. The area is formed continuously, and a steel wire can be installed between the cam lever and the shot lever in order to forcibly block the inflow of cold air by installing a tension spring between the cam lever and the shot lever. Forced to shut off.
이를 첨부도면에 의하여 설명하면 다음과 같다.This will be described with reference to the accompanying drawings.
걸림턱(1)(1')에서 캠둘레 1/2정도로 강영역과 약영역 곡면(2)(2')이 형성된 절환캠(3)에 있어 약영역곡면(2')와 걸림턱(1') 사이에 약영역곡면(2')의 반경보다 변화폭이 큰 폐쇄 영역 곡면(4)이 형성된 절환캠(3)을 형성하여 냉장실에 설치되는 템퍼장치의 절환노브(5) 축에 설치하면서 일측이 유동되게 설치된 캠레버(6)에 접하여 동작되게 하였다.The weak zone curved surface 2 'and the locking jaw (1) in the switching cam (3) having a strong zone and a weak zone curved surface (2) (2') formed at about 1/2 of the cam circumference from the catching jaw (1) (1 '). One side is formed between the switching knobs 5 of the tempering device installed in the refrigerating chamber by forming a switching cam 3 having a closed area curved surface 4 having a larger width of change than the radius of the weak region curved surface 2 'between'). This was in contact with the cam lever 6 provided to flow.
그리고 제1도 (a)(b)와 같이 온도감지부(7)에 연결된 벨로우즈(8)와 접동부(9)로 접하여 동작되고 힌지측(10)에 걸림유동 되는 샷터레버(11)와 상기 캠레버(6)를 인장스프링(12)으로 탄성력 있게 연결시키면서 인장 스프링(12)의 인장을 억제할 수 있는 강선(13)을 연결하여 인장 스프링(12)이 임의의 간격 이상 인장되는 것을 방지할 수 있게 하면서 절환노브(5)의 폐쇄회전에 의해 구동되는 절환캠(3)이 샷터레버(11)와는 인장 스프링(12)과 강선(13)으로 연결된 캠레버(6)를 작동시킴에 따라 샷터레버(11)를 힌지축(10)을 중심으로 이동시켜 샷터레버(11)에 연결된 샷터(14)가 냉장실의 냉기 유통로(15)를 정확하게 폐쇄시킬수 있게 설치한 것이다.And as shown in Fig. 1 (a) (b) and the bellows 8 and the sliding portion (9) connected to the temperature sensing unit (7) is operated in contact with the shot lever (11) and the fluid flow on the hinge side (10) By connecting the cam lever 6 to the tension spring 12 elastically and connecting the steel wire 13 that can suppress the tension of the tension spring 12 to prevent the tension spring 12 from being tensioned more than a certain interval. And the switching cam 3 driven by the closed rotation of the switching knob 5 operates the cam lever 6 connected to the shot lever lever 11 by the tension spring 12 and the steel wire 13. The lever 11 is moved around the hinge shaft 10 so that the shotter 14 connected to the shot lever 11 can close the cold air flow passage 15 of the refrigerating compartment accurately.
그리고 실예로 도면 제2도 (b)와 같이 캠레버(6)와 샷터레버(11) 사이에 턱걸림(16)(16')이 형성되는 정지편(17)(17')을 형성하여 평상시의 냉장으로 사용시에는 턱걸림(16)(16')이 간격 10을 유지할 수 있게 설치하였고, 그리고 도면 제2도 (c)와 같이 상기 턱걸림(16)(16') 사이에 완충 스프링(18)을 삽입시켜 완충효과를 주면서 캠레버(6)와 샷터레버(11)를 연결하는 인장 스프링(12)이 임의의 간격이상 인장되는 것을 방지하게 하였다.As an example, as shown in FIG. 2 (b), the stationary pieces 17 and 17 'are formed between the cam lever 6 and the shot lever 11 to form the jaw 16 and 16'. in the cold storage when used, the jaw engaging (16, 16 ') buffer spring between these was installed to maintain the gap 10, and the drawing FIG. 2 (c) and, as the jaw engaging (16) (16') ( 18) was inserted to prevent the tension spring 12 connecting the cam lever 6 and the shot lever 11 from being stretched at an arbitrary interval while providing a buffering effect.
그리고 도면 제2도 (d)와 같은 실시예에서는 샷터레버(11) 상측으로 일단을 스프링(19)에 탄성력 있게 설치시켜 축핀(20)으로 유동되게 설치시킨 작동편(21)의 타단 이 캠레버(6)에 접촉되게 하여 인장스프링(12)의 인장을 방지하며 샷터(7)를 고정시키게 구성한 것이다.And in the embodiment as shown in FIG. 2 (d), the other end of the operating piece 21 installed elastically installed on one end to the spring 19 to the upper side of the shot lever 11 to flow to the shaft pin 20 is cam lever By contacting the (6) to prevent the tension of the tension spring 12 is configured to fix the shot (7).
이와같이 된 본 고안의 작용효과를 상술하면 가스의 체적팽창을 이용하여 냉장실로 통하는 냉기 유통로(15)를 샷터(14)로 개폐시키는 냉장용 온도 조절기는 공지된 바 같이 제4도와 같이 형성된 것으로 온도감지부(7)의 온도가 상승하면 밀봉된 가스가 팽창함에 따라 벨로우즈(8)가 팽창하면서 샷터레버(11)를 ＂→＂ 방향으로 밀어 샷터레버(11)는 힌지축(10)을 중심으로 샷터(14)를 냉기 유통로(15)로부터 개방시켜 냉장실 내로 냉기를 유입시키게 되는 것이며, 냉장실 내의 온도가 하강함에 따라 온도 감지부(7)의 온도가 하강하면 밀봉된 가스의 체적이 감소하면서 벨로우즈(2)는 수축되고 캠레버(6)와 인장 스프링(12)으로 연결된 샷터레버(11)는 스프링의 복원력에 의해 ＂←＂ 방향으로 움직에서 샷터(14)는 냉기 유입구(15)를 막게되어 냉장실의 조절된 적정온도를 유지케 되는 것이다.As described in detail the effect of the present invention as described above, the temperature controller for refrigeration to open and close the cold air flow passage 15 through the shoter 14 through the volume expansion of the gas is formed as shown in FIG. When the temperature of the sensing unit 7 rises, as the sealed gas expands, the bellows 8 expands and the shot lever 11 is pushed in the direction of ＂→＂ so that the shot lever 11 moves about the hinge axis 10. Opens the shoter 14 from the cold air flow passage 15 to inject cold air into the refrigerating chamber. As the temperature in the refrigerating chamber decreases, the temperature of the temperature sensing unit 7 decreases, thereby reducing the volume of the sealed gas and bellows. (2) is contracted and the shot lever lever 11 connected to the cam lever 6 and the tension spring 12 is moved in the direction ＂← 의해 by the restoring force of the spring, the shoter 14 is blocked the cold air inlet 15 Regulated titration in the fridge The cake will be maintained.
만약 냉장실의 온도를 더 낮추고 싶어서 절환노브(5)를 ＂강＂쪽으로 회전시키면 제3도 (b)에서 반경이 작은 강영역 곡면(2)이 캠레버(6)와 접촉하므로 캠레버(6)는 하강되어 인장스프링(12)의 힘은 약화됨에따라 샷터 레버(11)가 벨로우즈(8)의 팽창을 방해하는 ＂←＂ 방향으로 작용하던 힘이 약화되어 동일 온도에서의 벨로우즈(8)의 팽창량은 절환노브(5)에서 ＂약＂ 쪽으로 회전시켰을때 보다도 ＂강＂ 쪽으로 회전 시켰을때가 더 많아서 샷터레버(11)를 더 크게 밀어 줄수 있어 냉기 유입량을 증대시켜 온도를 낮게 유지할 수 있는 것이다.If you want to lower the temperature of the refrigerating chamber further and rotate the switching knob (5) toward the steel cavity, the cam lever (6) because the steel zone curved surface (2) of small radius in contact with the cam lever (6) in FIG. As the force of the tension spring 12 decreases, the force acting in the direction of ＂←＂ of the shoter lever 11 that hinders the expansion of the bellows 8 is weakened, thereby expanding the bellows 8 at the same temperature. The amount is more than when rotated to the 노 ＂에서 direction in the switching knob (5) to push the shot lever (11) larger to increase the cold air inflow can be maintained to keep the temperature low.
상기와 같은 온도 조절기에 있어서 본 고안은 절환노브(5)를 ＂강∼약＂ 사이에서 조절하면 도면 제1도 (b) 상태에서와 같이 절환캠(3)은 강영역 및 약영역 곡면(2)(2')에 캠레버(6)와 접촉되어 이 경우에는 캠레버(6)와 샷터레버(11)를 연결한 강선(13)을 느슨한 상태로 있기 때문에 작동되지 않고 인장스프링(12)만 정상상태로 작동되어 전술한 바와같은 원리로 냉장실은 냉장온도를 유지하게 되는 것이다.The present invention in the temperature controller as described above, if the switching knob (5) is adjusted between ＂strong ~ weak＂ as shown in Figure 1 (b) of the switching cam (3) is a strong zone and weak zone curved surface (2) (2 ') is in contact with the cam lever 6 and in this case, since the steel wire 13 connecting the cam lever 6 and the shot lever 11 is in a loose state, only the tension spring 12 is not operated. The refrigerator operates in a normal state and maintains the refrigerating temperature on the principle as described above.
그러나 절환노브(5)를 ＂폐쇄”로 셋팅하면 제3도 (b)에서 절환캠(3)의 폐쇄영역 곡면(4)이 캠레버(6)와 도면 제1도 (a)와 같이 접촉됨에 따라 이 경우에는 강선이 샷터레버(13)를 ＂”방향으로 강제로 당기게 되기 때문에 샷터레버(11)는 벨로우즈 (8)를 ＂←” 방향으로 강제로 압축하면서 샷터(14)를 강제로 닫게하여 냉장실은 어떠한 온도에서도 냉기가 유입될 수 없는 것이고 온도 감지부(7)의 온도가 상승될 경우 밀봉된 가스의 압력만 상승할뿐 벨로우즈(8)는 팽창할 수 없어서 어떠한 온도에서도 샷터(14)는 개방되지 않아 ＂폐쇄”상태가 되는 것이다.However, when the switching knob 5 is set to "closed closing", the closed area curved surface 4 of the switching cam 3 is in contact with the cam lever 6 as shown in FIG. 1 (a) in FIG. Therefore, in this case, the steel wire breaks the shot lever (13). The shot lever (11) is forced to close the shot (14) while forcibly compressing the bellows (8) in the direction of "＂ ← "because it is forcibly pulled in the direction of the When the temperature of the sensing unit 7 rises, only the pressure of the sealed gas rises, but the bellows 8 cannot expand, and the shot 14 is not opened at any temperature, and thus the state is closed.
이때 강선(11)은 인장스프링(12)의 스프링 정수가 급격히(거의 무한대까지) 상승될 수 있도록하며 인장스프링(12)이 임의의 간격 이상으로 인장되는 것을 방지할 수 있는 효과가 있는 것이다.At this time, the steel wire 11 is to enable the spring constant of the tension spring 12 to rise sharply (to almost infinity) and to prevent the tension spring 12 from stretching beyond a certain interval.
본 고안의 다른 실시예로 제2도 (a)는 강선(11)을 인장스프링(12) 내부에 설치하여 같은 효과를 얻을 수 있는 것이며, 제2도 (b)와같이 캠레버(6)와 샷터레버(11)의정지편(17)(17')이 턱걸림(16)(16')으로 10＞0 상태에 있다가 냉장실이 폐쇄할때 턱걸림(16)(16')이 맞붙어 걸려서로 마치 강선이 작용하는 것과 같이 샷터레버 (11)를 강제로 이동시켜 샷터(14)가 냉기 유통로(15)를 닫히게 할수 있는 것이며, 제2도 (c)와 턱걸림(16) (16') 사이의 완충스프링(18)을 삽입시켰을 때에는 완충스프링 (18)이 냉장실에 최고로 상승하는 온도때의 팽창력보다 완충력을 크게 설계하여야 하는 것이다. 그리고 제3도 (d)와같이 캠레버(6)가 실선과 같이 절환캠(3)의 냉장 영역에 접촉될 때에는 샷터레버(11)에 아무런 작용을 하지 않으나 절환캠(3)의 폐쇄 영역인 가상선과 같이 캠레버(6)와 접촉될 때에는 캠레버(6)가 작동편(21)을 샷터레버 (11)측으로 강제로 밀어서 샷터(14)를 닫게 하게 하는 것이다.In another embodiment of the present invention 2 (a) is a steel wire 11 can be obtained by the same effect by installing the inside of the tension spring 12, as shown in FIG. 2 (b) and the cam lever 6 and When the stop pieces 17 and 17 'of the shot lever 11 are in a state of 1 0 > 0 with the jaws 16 and 16', the jaws 16 and 16 'are engaged when the refrigerator closes. As a steel wire is applied, the shot lever 12 can be forcibly moved so that the shot machine 14 can be closed by the cold flow path 15. FIG. 2 (c) and the jaw 16 (16) When the shock absorbing spring 18 is inserted, the shock absorbing force 18 should be designed to be larger than the expansion force at the temperature at which the shock absorbing spring 18 rises to the refrigerating chamber. When the cam lever 6 contacts the refrigerating area of the switching cam 3 like a solid line as shown in FIG. 3 (d), the cam lever 6 does not act on the shot lever 11 but is closed in the switching cam 3. When the cam lever 6 comes into contact with the cam lever 6 like an imaginary line, the cam lever 6 pushes the operation piece 21 toward the shot lever 11 to close the shot 14.
이와같이 본 고안은 냉장실 온도조절의 절환노브(5)를 ＂강-약＂ 사이에 셋팅해 놓으면 종전과 같은 냉장실 온도조절기로 작동되나 ＂폐쇄＂ 위치에 셋팅해 놓으면 온도 조절기내의 인장스프링(12)의 임의의 간격이상으로 인장되는 것을 방지하며 온도 조절기로서의 기능을 상실한채 냉기 유통로(15)로 냉기의 유입을 강제로 차단 시킬수 있는 것이다.As such, the present invention operates the refrigerating chamber temperature controller when the switching knob 5 of the refrigerating chamber temperature control is set between ＂strong and weak, but when it is set to the＂ closed position, the tension spring 12 of the temperature controller is It is possible to forcibly block the inflow of cold air into the cold air flow passage 15 while preventing the tension beyond a predetermined interval and losing its function as a temperature controller.
