본고안은 본인의 선출원 실용신안 제94-31471호인 외측 밸브기능으로 된 압력솥의 증기배출장치에 압력표시핀을 부설한 것으로서, 특히 이들 양기능이 제기능을 다할 수 있도록 한 것이다.This proposal is to install the pressure indicator pin on the steam discharge device of the pressure cooker with the outer valve function of my prior application model No. 94-31471, in particular, so that both of these functions to function.
종래에도 압력표시핀이 일체로 구성된 압력솥의 안전밸브장치가 있었으나 이들 대부분이 제3도에 도시된 바와 같이 압력표시핀(100)의 내부에 안전밸브장치(102)를 구성토록 하므로서 압력표시핀(100)의 무게가 무거워 저압에서는 감지가 불가능하고, 또한 안전밸브장치(102)도 압력표시핀(100)의 좁은 관체내에 설치되어 있어 배출로(104)가 매우 좁게 형성될 수밖에 없고 배출기능도 밀폐구(106)가 배출로(104)에 탄력 설치된 스프링(108)의 내측으로부터 밀폐시켜 주도록 한 내측 밸브기능으로 되어 있어 과압력 발생시 증기와 함께 배출되는 조리물의 찌꺼기가 좁은 배출로(106)를 통과하면서 스프링(108)에 걸려 적체되거나 배출구(110)(112)를 차단시켜 결국 안전사고를 유발시키게 되므로 안전밸브로서의 기능도 저하되는 문제점이 있는 것이다.In the related art, there has been a safety valve device of a pressure cooker in which a pressure display pin is integrally formed. However, most of them have a safety valve device 102 formed inside the pressure display pin 100 as shown in FIG. Due to the heavy weight of 100), it is impossible to detect at low pressure, and the safety valve device 102 is also installed in a narrow tube of the pressure display pin 100 so that the discharge passage 104 is formed to be very narrow, and also has a discharge function. The sealing opening 106 has an inner valve function for sealing from the inside of the spring 108 resiliently installed in the discharge passage 104, so that the residue of the food discharged with steam in the event of an overpressure is formed in the narrow discharge passage 106. While passing through the spring 108 is stuck or blocked outlet 110, 112 will eventually cause a safety accident, so there is a problem that the function as a safety valve is also reduced.
그리고 안전밸브기능을 강화시켜 주기 위하여 압력표시핀의 관체 직경을 크게 하여 배출로를 넓혀 줄 경우에는 관체의 직경이 커진만큼 안전표시핀도 그만큼 더 커지게 되므로 설치공간을 많이 차지하고 재료비가 더 소요되며, 또한 투박하여 외관이 미려하지 못하게 됨은 물론 특히 압력표시핀의 무게가 가중되므로 안전밸브기능을 강화시켜 주는 만큼 압력표시핀의 기능은 저하되는 등의 많은 문제점들이 있는 것이었다.In addition, in order to increase the safety valve function, if the diameter of the pressure indicator pin is enlarged to widen the discharge path, the larger the diameter of the tube, the larger the safety indicator pin will be. In addition, there were many problems such as the appearance of the sluggish appearance, as well as the weight of the pressure display pin, in particular, the weight of the pressure display pin is increased, thereby enhancing the safety valve function.
본고안은 이와 같은 종래에 문제점들을 해결하기 위하여 외측 밸브기능으로 된 안전밸브장치내에 압력표시핀을 설치하여 안전밸브로서의 기능을 충분히 발취할 수 있도록 하면서도 압력표시핀이 외부의 간섭없이 자체 무게에 의해서만 승강작동될 수 있도록 하여 미압까지도 감지할 수 있도록 함을 목적으로 한 것이다.In order to solve such problems in the related art, the present invention installs a pressure indicator pin in a safety valve device having an outer valve function to sufficiently extract the function as a safety valve, but the pressure indicator pin is driven by its own weight without external interference. It aims to be able to detect lifting even by lifting and lowering operation.
상기한 목적을 달성하기 위하여 본고안은 안전밸브장치의 승강대를 상하로 분리 구성하되 그 내부에는 크기가 다른 작동공을 상하로 관통되게 형성하여 중앙에 걸림테가 형성된 압력표시핀을 작동공에 끼워지게 하여 상하 승강봉을 나사 결합해 주므로서 압력표시핀이 상부 승강봉의 걸림턱과 하부 승강봉의 상단부 사이에서 승강작동되도록 한 것으로서 본고안의 일실시예를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.In order to achieve the above object, the subject of the present invention is to separate the lifting platform of the safety valve device up and down, and to form a working hole having a different size up and down through the inside thereof so that a pressure indicator pin having a hook frame in the center is inserted into the working hole. By screwing the upper and lower elevating rods so that the pressure display pin is raised and lowered between the engaging jaw of the upper elevating rod and the upper end of the lower elevating rod, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
압력솥(도시않됨)의 뚜껑(2)에 너트(4)로 체결 고정된 고정구(6)의 내측 배출공(8)에 승강대(10)를 다소 헐겁게 끼워 승강대(10)의 상부밀폐링(12)이 배출공(8) 상부로부터 밀폐시켜 주도록 하고 배출공(8)의 측면 유입구(14)(15)(16) 내측 아래에 형성된 걸림테(18)와 승강대(10)의 하부 걸림턱(20) 사이에는 스프링(21)을 탄력 설치하여 외측 밸브기능을 갖도록 한 압력솥의 안전밸브장치에 있어서, 승강대(10)를 상하 승강봉(22)(24)으로 분리 구성하여 상부 승강봉(22) 내측에는 직경이 큰 작동공(26)을 형성하되 그 상부에는 걸림테(28)와 안내공(30)을 형성하고 하부 승강봉(24)에는 직경이 작은 작동공(32)을 유입공(34)과 관통되게 형성한 뒤 상부 승강봉(22)의 작동공(26)하부와 하부 승강봉(24)의 상부 외면에 나선(34)(36)을 형성하여 서로 나사 결합되도록 한다.The upper sealing ring 12 of the lifting platform 10 by loosely fitting the lifting platform 10 to the inner discharge hole 8 of the fixture 6 fastened and fixed to the lid 2 of the pressure cooker (not shown) by the nut 4. It is to be sealed from the upper side of the discharge hole (8) and the lower engaging jaw (20) of the hook frame 18 and the lifting platform 10 formed on the inner side of the outlet inlet 14, 15, 16 inside the discharge hole (8) In the safety valve device of the pressure cooker elastically installed between the spring 21 to have an outer valve function, the lifting table 10 is separated into the upper and lower lifting bars 22 and 24 to be inside the upper lifting bar 22. A large diameter operating hole 26 is formed, and a hook frame 28 and a guide hole 30 are formed at an upper portion thereof, and a lower diameter operating hole 32 is formed at an inlet hole 34 at a lower lifting rod 24. After being formed to penetrate, the spiral holes 34 and 36 are formed on the lower outer surface of the operation hole 26 of the upper elevating rod 22 and the upper elevating rod 24 to be screwed together.
상하에 굵기가 다른 안내봉(38)(40)이 일체로 형성된 경금속재 압력표시핀(42)의 중앙에는 걸림테(44)를 형성하고 걸림테(44)의 상부에는 연질의 밀폐링(46)을 끼운뒤 압력표시핀(42)을 상부 승강봉(22)의 작동공(26) 저부로부터 삽입하여 상부 안내봉(38)은 걸림테(28)의 내측 안내공(30)에 끼워지게 하고 하부 안내봉(40)은 하부 승강봉(24)의 작동공(32)에 끼워지게 한 상태로 상하 승강봉(22)(24)을 나사 결합하여 승강대(10)를 구성토록 하여서 된 것이다.Upper and lower guide bars 38 and 40 having different thicknesses are formed in the center of the light metal pressure display pin 42 integrally formed with a hook frame 44 and a soft sealing ring 46 at the top of the hook frame 44.

이와 같이 구성된 본고안은 압력솥(도시않됨)에 열을 가하기 전에는 압력표시핀(42)이 하강하여 걸림테(44)가 하부 승강봉(24)의 상단부와 접한 제1도의(a) 상태가 되며, 이 상태에서 압력솥에 열을 가하여 내부에서 미압이라도 발생되면 이 압력이 보호캡(48)의 유입공(50)(52)(54)을 통하여 하부 승강봉(24)의 작동공(32) 저부로부터 유입되어 경금속재로 된 압력표시핀(42)을 밀어 올리게 되므로 압력표시핀(42)이 제1도(b)에 도시된 바와 같이 상승하여 걸림테(44) 상부의 밀폐링(46)이 상부 승강봉(22)의 걸림턱(28)과 접하여 외부와는 밀폐되도록 하고 상부 안내봉(38)은 승강대(10)의 외측 상부로 돌출되어 압력표시핀(42)으로서의 역할을 하게 된다.In this configuration configured as described above, before the heat is applied to the pressure cooker (not shown), the pressure indicating pin 42 is lowered, and the hook frame 44 is in the state of FIG. 1 (a) in contact with the upper end of the lower lifting bar 24. In this state, if pressure is generated inside the pressure cooker even if the pressure is generated inside, the pressure is lowered through the inlet hole 50, 52, 54 of the protective cap 48. Since the pressure indicator pin 42 made of light metal is pushed up, the pressure indicator pin 42 rises as shown in FIG. In contact with the locking projection 28 of the upper elevating rod 22 to be sealed to the outside and the upper guide rod 38 is protruded to the outer upper portion of the lifting table 10 to serve as a pressure display pin 42.
그리고 조리시 과압력이 발생되면 고정구(6)의 유입구(14)(15)(16)로 유입된 과압력이 고정구(6)와 승강대(10) 사이에 다소 넓게 형성된 배출공(8)을 통하여 스프링(21)으로 탄력 설치된 승강대(10)를 밀어 올려 승강대(10)의 밀폐링(12)으로 차단하고 있던 배출공(8)을 개방시키게 되므로 증기에 포함된 조리물의 찌꺼기까지도 넓은 배출공(8)을 통하여 용이하게 배출이 되며, 과압력 발생이 중지되면 승강대(20)는 스프링(21)의 반발력으로 하강하여 밀폐링(12)이 고정구(6)의 배출공(8) 상부를 다시 차단시켜 주게 된다.And when the overpressure occurs during cooking, the overpressure introduced into the inlet 14, 15, 16 of the fixture 6 through the discharge hole 8 is formed somewhat wider between the fixture 6 and the platform 10 Pushing the platform (10) elastically installed by the spring (21) to open the discharge hole (8) blocked by the sealing ring 12 of the platform (10), so that even the dregs of food contained in the steam (8) Easily discharged through the), when the overpressure stops, the platform 20 is lowered by the repulsive force of the spring 21, the sealing ring 12 to block the upper part of the discharge hole 8 of the fixture 6 again Given.
조리후 불을 끈 상태에서도 압력솥 내부에 약간의 미압이라도 잔존해 있게 되면 압력표시핀(42)은 승강대(10)의 외측 상부로 돌출된 상태로 유지되며 압력솥 내부의 압력이 거의 소멸되면 압력표시핀(42)은 자중에 의해 하강하여 제1도의(a) 상태가 되므로 이를 확인한 조리자는 뚜껑(2)을 개방시켜 주면 되는 것이다.Even after the fire is turned off after cooking, even if a slight pressure remains inside the pressure cooker, the pressure display pin 42 is maintained to protrude to the outside of the platform 10 and the pressure display pin when the pressure in the pressure cooker almost disappears. 42 is lowered due to its own weight, so that it becomes a state of FIG. 1 (a), so that the cooker who checks this can open the lid 2.
이상 설명한 바와 같이 본고안은 스프링(21)에 탄력 설치된 승강대(10)의 밀폐링(12)이 고정구(6)의 배출공(8) 상부로부터 차단시켜 주도록 한 외측 밸브기능의 안전밸브장치 내측에 압력표시핀(42)을 부설해 주므로서 안전밸브기능과 압력표시핀(42)의 기능을 충분히 발휘할 수 있는 보다 안전하고 실용적인 압력솥을 제공할 수 있게 되는 것이다.As described above, the present proposal has a safety valve device having an outer valve function which allows the sealing ring 12 of the platform 10 elastically installed on the spring 21 to be blocked from the upper portion of the discharge hole 8 of the fixture 6. By providing the pressure display pin 42, it is possible to provide a more safe and practical pressure cooker capable of fully exhibiting the function of the safety valve function and the pressure display pin 42.
