Vacuum energy-saving thermal insulation pressure cooker

Abstract

The invention provides a vacuum energy-saving thermal insulation pressure cooker which comprises a pot body, a pot bottom and a pot cover. The pot body is of a two-layer vacuum structure, and comprises a pot body inner layer and a pot body outer layer. The pot body inner layer comprises a side wall and a bottom wall. The pot body inner layer is embedded in the pot body outer layer. The pot body outer layer is closely connected to the side wall of the pot body inner layer through laser welding. A first vacuum cavity is formed between the pot body inner layer and the pot body outer layer. The pot bottom comprises an aluminum layer and a stainless iron layer. The bottom wall of the pot body inner layer, the aluminum layer and the stainless iron layer are welded under pressure and closely connected together. The pot cover is of a two-layer vacuum structure, and comprises a pot cover inner layer and a pot cover outer layer. The pot cover inner layer is embedded in the pot cover outer layerthrough laser welding. A second vacuum cavity is formed between the pot cover inner layer and the pot cover outer layer. By means of the vacuum two-layer pot body and the vacuum two-layer pot cover, thermal insulation performance is improved; the pot bottom is a multi-layer compound bottom, is firm, durable and rapid in heat conduction and can be uniformly heated, and therefore energy conservation, time conservation, high efficiency and scald prevention are realized.

Description

technical field [0001] The invention relates to a heating container, in particular to a vacuum energy-saving heat preservation pressure cooker. Background technique [0002] The pressure cooker utilizes that the boiling point of water will increase under higher pressure to speed up the efficiency of stewing food, so that the boiling point of water can be increased to above 100°C, thereby realizing the characteristics of energy saving, time saving and high efficiency. However, the pressure cookers sold on the market today have reached the maximum in terms of energy saving, time saving, and high efficiency. Whether we can find a suitable method to further improve the performance of the pressure cooker is a technical problem that we need to consider next. It is quite difficult. [0003] The working pressure of the pressure cooker on the existing market is generally 80kPa, and someone thinks of increasing the working pressure range of the pressure cooker to realize further impr...
