An energy-saving steam sterilization pot includes a pot body and a pure water vapor generating tube. The inside of the pot body forms a sterilization chamber. The wall of the pot is tied inside to form a sandwich and has at least one steam inlet connected to the outside by the sandwich. The steam inlet can introduce general water vapor into the interlayer, and the pure water vapor generating pipe is coiled in the interlayer, which can be used for introducing pure water and then heating the high-temperature general water vapor in the interlayer to form pure water vapor. Into the sterilization chamber； this can avoid contamination of the items to be sterilized and save consumables and energy costs.一種節能蒸氣滅菌鍋，包括一鍋體及一純水蒸氣產生管，該鍋體的內部形成一滅菌室，鍋壁係於內部形成一夾層及具有由該夾層連通到外部之至少一蒸氣入口，該蒸氣入口可將一般水蒸氣導入到該夾層之中，該純水蒸氣產生管係盤繞於該夾層之中，可供導入純水然後經由該夾層中之高溫一般水蒸氣加熱形成純水蒸氣後送入該滅菌室之中；藉此係可避免欲滅菌物品受污染以及可節省耗材與能源成本。
