Pressure vessel capable of rapidly reducing pressure

Abstract

The invention discloses a pressure vessel capable of rapidly reducing pressure. The pressure vessel comprises an inner container and a thermoelectric refrigeration galvanic couple; the thermoelectricrefrigeration galvanic couple comprises a cold end face and a hot end face; the cold end face of the thermoelectric refrigeration galvanic couple is attached to the outer side wall face of the inner container, and after the thermoelectric refrigeration galvanic couple is powered on, the cold end face can rapidly absorb heat from the inner container and release the heat to the surrounding environment through the hot end face; according to the technical scheme, the thermoelectric refrigeration galvanic couple is arranged on the outer wall of the inner container, rapid cooling and pressure reduction can be achieved, and rapid uncovering after heating is completed is facilitated; according to the technical scheme, exhaust is not needed in the cooling and depressurizing process, and the situation that liquid or fluid in the container is sprayed out along with the exhaust process to pollute appliances or the environment is avoided; the thermoelectric refrigeration galvanic couple is arrangedon the outer wall of the inner container, the overall sealing performance is not damaged, and the risk of air leakage and liquid leakage is avoided; the pressure vessel capable of rapidly reducing the pressure is high in cooling and pressure reducing speed, can start constant-power refrigeration after being powered on, and is simple and convenient to operate.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a pressure vessel with rapid decompression. Background technique [0002] At present, pressure containers such as household electric pressure cookers have a pain point, that is, the lid cannot be opened immediately after the heating is completed, because there is residual pressure inside the container at this time, and the user needs to wait for the container to cool down, and the pressure is gradually reduced to the same as the atmospheric pressure before opening the lid. , This process generally takes 10-20 minutes. In addition, there is another structure, that is, a pressure release valve is provided on the container cover. After the heating is completed, the pressure release valve is triggered manually or automatically by a program. The pressure release time is about 3-5 minutes. Although this structure speeds up the exhaust, it brings Another pain point is that the liquid or fluid in th...
