the heat preservation pan of this embodiment is used for steam heating, is equipped with the inlet channel 110 that supplies steam to let in on pot cover 100, and pot cover 100 lid closes inner bag body 220 courage mouth and seals when the pot body 200, forms the culinary art space. During cooking, steam is generated by an external steam generating device and is introduced into the cooking space or the inside of the food through the air inlet passage 110. Among the prior art, adopt the cooking utensil of dish heating or electromagnetic wire coil induction heating that generates heat, heat the inner bag earlier during the culinary art, heat food by the inner bag again, compare under, the heating efficiency of steam heating is higher, and heating uniformity is better, and more different is, among the steam heating process, the steam heat is by the transmission of culinary art space to inner bag body 220 for the inner bag body 220 inside and outside space produces the bigger difference in temperature, and the comdenstion water that condenses is changeed to inner bag body 220 inner wall.

In order to solve the problem of condensed water, the key point is to balance the temperature difference between the inner space and the outer space of the inner container 220, in this embodiment, a heat-locking layer 240 and a heat-insulating layer 230 are arranged in the cavity of the pot body 200, the heat-locking layer 240 is separated between the inner container 220 and the heat-insulating layer 230, and the heat-locking layer 240 is an air layer. The heat-locking layer 240 weakens the heat conduction of the inner container 220 to the heat-insulating layer 230 between the inner container 220 and the heat-insulating layer 230, the heat-insulating layer 230 is between the outer container 210 and the heat-locking layer 240, and weakens the heat conduction of the heat-locking layer 240 to the inner container 210, and the heat-locking layer 240 is an air layer, so that most of the heat dissipated by the inner container 220 can be maintained in the heat-locking layer 240, therefore, in the cooking process, the temperature of the heat-locking layer 240 can approach the internal temperature of the inner container 220 in a short time, namely, the function of balancing the internal and external temperature differences of the inner container 220 is achieved, the condensation effect on the inner side of the inner container 220 is weakened, the condensation amount of the condensed water on the inner wall of the inner container 220 is reduced, and the problem of a large amount of condensed water on the inner wall of the inner container 220 caused by the excessive.

It should be noted that, the liner body 220 described in this embodiment is generally a metal liner body, for example, a food-grade stainless steel liner body, the wall thickness of the metal liner body is very small, the heat conduction effect is good, and in the cooking process, because the rapid heat conduction of the liner body 220 makes the outer wall temperature of the liner body 220 and the temperature of the cooking space substantially equal, correspondingly, the temperature of the heat locking layer 240 can be closer to the temperature of the cooking space.

In this embodiment, the heat insulation layer 230 is an independently installed heat insulation member, the heat insulation member is made of heat insulation material, such as glass fiber, asbestos, rock wool, etc., and the heat insulation member is not limited to a single-layer structure, and according to actual needs, the heat insulation member may also be a mixed structure or a multi-layer structure formed by compounding multiple heat insulation materials.
