본 발명은 압력솥의 안전밸브에 관한 것으로서, 상세하게는 오랜 사용에 의한 밀폐링의 마모시에도 기능상실 우려가 없고 또 이물질의 적체로 인한 오작동우려가 없으며 소제가 용이하게 이루어질 수 있도록 한 것이다.The present invention relates to a safety valve of a pressure cooker, and in particular, there is no fear of loss of function even when the sealing ring is worn due to long use, and there is no fear of malfunction due to accumulation of foreign matters, so that cleaning can be easily performed.

압력솥의 안전밸브에 대하여는 이미 여러건이 제공된바 있으나 이들 모두는 도 4에서와 같이 뚜껑(50)에 대하여 안내관(52)이 갖는 머리부와 상기 안내관 저부로부터 나사결합되는 너트(54)에 의해 고정되고, 단면 "O"형의 밀폐링(56)이 끼워지는 돌출부와 걸림부로 구성되며, 내부에 미압표시봉(57)이 설치되는 주압슬리브(58)는 안내관(52)의 작동공 상하로부터 나사결합되고, 스프링(60)은 주압슬리브(58)의 결합전 걸림부에 끼워져 안내관(52)의 작동공 하부에 갖는 걸림테와 걸림부가 갖는 걸림테 사이에 탄력설치되어 밀폐링(56)이 안내관(52) 상부에 갖는 접촉면과의 긴밀한 접촉으로 밀폐가 이루어지도록 구성된다.Several have already been provided for the safety valve of the pressure cooker but all of them are provided by the head of the guide tube 52 with respect to the lid 50 and the nut 54 screwed from the bottom of the guide tube as shown in FIG. The main pressure sleeve 58, which is fixed and includes a protrusion and a locking portion into which the sealing ring 56 of the cross section “O” type is fitted, is installed with a micro pressure display rod 57 therein. Screwed from the spring, the spring 60 is fitted to the engaging portion before the coupling of the main pressure sleeve (58) is elastically installed between the engaging frame having a lower portion of the operating hole of the guide tube 52 and the engaging frame having a locking ring (56) ) Is configured to be closed by intimate contact with the contact surface having the upper portion of the guide tube 52.

그러나 이러한 구조의 안전밸브는 주압슬리브(58)가 갖는 단면"O"형의 밀폐링(56)이 안내관(52)의 접촉면과 단순접촉으로 밀폐되므로 밀폐능력이 떨어져 조리가 제대로 이루어질 수가 없고 또 오랜 사용에 의한 마모시에는 곧바로 기능상실로 이어져 제품에 대한 불신을 가져올 뿐 아니라 잦은 A/S로 비용부담이 가중된다.However, the safety valve of such a structure is closed because the sealing ring 56 of the end face "O" type of the main pressure sleeve 58 is simply contacted with the contact surface of the guide tube 52, so the sealing ability is poor, and cooking cannot be performed properly. In case of abrasion by long use, it leads to malfunction and not only distrust on the product, but also costly with frequent A / S.

또한 안내관(52) 하부의 작은 스프링실 내에 설치되는 스프링(60)은 길이가 짧은만큼 요구되는 강한 반발력을 얻기 위하여 코일 간격이 좁게 형성되므로 조리중 발생되는 이물질들이 스프링실 내에 끼어 오작동에 의한 안전사고를 가져올 우려가 있고 또 주압슬리브를 완전분해해 주어야만 스프링과 스프링실이 노출되므로 소제가 용이하지 못한 등의 많은 문제점들이 지적되고 있는 것이다.In addition, the spring 60 installed in the small spring chamber under the guide tube 52 has a narrow coil spacing in order to obtain the strong repulsion force required by the short length, so that foreign matters generated during cooking are caught in the spring chamber to prevent safety from malfunction. There is a risk of accidents, and since the main pressure sleeve is completely disassembled, the spring and the spring chamber are exposed, so many problems are pointed out.

본 발명은 상술한 종래기술이 갖는 문제점들을 감안하여 주압슬리브를 밀폐하는 밀폐링의 성능이 우수하고 오랜 사용에 의한 마모시에는 기능상실우려가 없어 제품에 대한 불신감을 해소하고 또 A/S비용을 줄일 수가 있으며, 이물질의 적체로 인한 오작동방지로 안전사고를 예방해 줄 수 있을뿐 아니라 소제가 용이하게 이루어질 수가 있는 압력솥의 안전밸브를 제공하고자 한다.The present invention is excellent in the performance of the sealing ring for sealing the main pressure sleeve in consideration of the problems of the prior art described above, there is no fear of functional loss when worn by long use to solve the distrust of the product and A / S cost It is possible to reduce and prevent the malfunction due to the accumulation of foreign matters to prevent safety accidents as well as to provide a safety valve of the pressure cooker that can be easily cleaned.
