Abstract

스텐레스 진공보온병의 단열주벽 진공밀폐방법 및 그 밀폐구조를 제공함에 의해 달성되게 되는데, 이 진공보온병의 단열부주벽은 내 · 외주벽이 적당한 간격을 가지고 이중적으로 중첩 설치되어 구비되는 진공실을 갖고있고, 이의 단열주벽 바닥면 적당한 장소에 구비되는 배기공의 주위를 적당한 너비로 프레스가공하여 그 단열주벽 표면으로부터 다소 내려앉은 블랭크를 구성하고 있다. 그리고 이의 블랭크내에 그 블랭크의 체적보다는 다소적게 소결시킨 알루미나 규소계의 세라믹밀폐 부재를 넣고 최종단계의 진공노에서 약 900℃이하 온도에서 소성가공처리 하여 블랭크 소지(素地)에 소부되어 배기공을 밀폐시키게 하고 있다. 따라서 소비전력을 절감하고 진공도를 높이어 보온성을 향상시키게 된다.Insulating circumferential wall of stainless steel vacuum thermos is achieved by providing a vacuum sealing method and a sealed structure thereof, the circumferential wall of the thermal insulation portion of the vacuum thermos has a vacuum chamber in which the inner and outer circumferential wall is overlapped and installed in a double overlap, The insulation circumferential wall bottom surface is press-processed to the appropriate width around the exhaust hole provided in a suitable place, and the blank part which fell slightly from the surface of the insulation circumference wall is comprised. In the blank, alumina-silicon-based ceramic sealed member sintered a little less than the volume of the blank is put in a plastic furnace at a temperature of about 900 ° C. or lower in a vacuum furnace at the final stage to be baked into the blank body to seal the exhaust hole. Is letting go. Therefore, the power consumption is reduced and the degree of vacuum is increased to improve the insulation.
