Pressure cooker and pressure relief method thereof

Abstract

The invention relates to a pressure cooker and a pressure relief method thereof, wherein the pressure cooker includes a cover body, a pot body provided with an inner tank, and a pressure-relief chamber which is independent from the inner tank. The pressure relief valve is provided with a pressure relief switch between the pressure relief chamber and the inner tank, so that the pressurized gas in the inner tank can be discharged into the pressure relief chamber through the pressure relief switch, and then discharged through the pressure relief valve. The pressure relief method includes: when the food in the pressure cooker is cooked, turn on the pressure relief switch, so that the pressurized gas in the inner tank is discharged into the slow pressure chamber through the pressure relief switch, and then discharged through the pressure relief valve. By setting a pressure-relief chamber in the pressure cooker independent of the inner container, the pressure-relief chamber can effectively buffer the impact caused by the rapid release of the pressurized gas in the inner container of the pressure cooker, so that the pressurized gas can be quickly discharged from the inner container into the pressure-relief chamber, The air pressure in the inner tank of the pressure cooker can reach the safe pressure in advance, reducing the waiting time for opening.

Description

technical field [0001] The invention relates to the field of living kitchen utensils, in particular to a pressure cooker and a pressure relief method thereof. Background technique [0002] Pressure cooker is also called pressure cooker, has been widely used in people's life at present, the structure of existing pressure cooker is as follows figure 1 As shown, it includes a pot body a1, a cover body a2 and a pressure relief valve a3 arranged on the top of the cover body a2. Enjoy delicious wait times and save energy. However, after the food is cooked, it is necessary to open the pressure relief valve a3 for a period of time to release the pressure. The pressure relief should not be too high, otherwise it will cause an impact on the external environment and cause danger. This process still needs to wait for a period of time before consumers can enjoy Delicious, that is to say, although the existing pressure cooker reduces the cooking time due to pressurization, it increases ...

AI Technical Summary

Problems solved by technology

However, after the food is cooked, it is necessary to open the pressure relief valve a3 for a period of time to release the pressure. The pressure relief should not be too high, otherwise it will cause an impact on the external environment and cause danger. This process still needs to wait for a period of time before consumers can enjoy Delicious, that is to say, although the existing pressure cooker reduces the cooking time due to pressurization, it increases the waiting time for pressure release, which virtually weakens the practical value of the pressure cooker. Therefore, the common pressure release method of the existing pressure cooker has a leak Slow and unsafe defects, need further improvement
