PROBLEM TO BE SOLVED: To provide a cooking device having a function for performing cooking at an appropriate specified low temperature of 100°C or less, simple and fast cooking and enabling full simmering cooking to be carried out as well as non-heated penetration and enabling the cooked foods to be re-heated at an appropriate temperature of 100°C or less as a compact and easy-to-use cooking device.SOLUTION: This invention relates to a cooking unit comprising two containers of nested structure, a vacuum pump 3, a vacuum piping of which changing-over control can be carried out, a heat source 15 and a thermostat. Heating during cooking is performed with saturated-steam under vacuum so as to perform a vacuum-penetration cooking, a low temperature steam bath cooking carried out at a vacuum steam chamber 7 and a low temperature steam discharge cooking that is carried out at a sealed cooking container kept in a vacuum steam chamber. Further, a top plate 5 is covered by a top lid 6.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】100℃未満の低い適正な一定の温度での調理を行い、簡潔で速やかな調理を行い、煮詰める調理も可能であり、更に非加熱浸透が出来る機能を備え、更に調理したものを100℃未満の適正な温度で再加熱できる調理器を、コンパクトで使い易い調理器として提供する事。【解決手段】入れ子構造にした2つの容器と、真空ポンプ3と、切替え制御操作の可能な真空配管と、熱源15と、サーモスタットとで構成する事で、調理に於いての加熱を真空下の飽和蒸気で行い、真空浸透の調理と、真空にした蒸気室7で行う低温スチームバスの調理と、真空にした蒸気室の中の密封調理容器で行う低温スチームディスチャージの調理とを行う調理器とし、さらに、天盤5を天蓋6で覆う。【選択図】図1
