Low-pressure quick-cooking pot with air overflow chamber and control method thereof

Abstract

The invention relates to a low-pressure quick-cooking pot with an air overflowing chamber, which comprises an outer pot and an inner pot, wherein the outer pot is divided into an upper part and a lower part; the caliber of the upper peripheral wall of the outer pot is larger than that of the lower peripheral wall of the outer pot; an annular space of the inner side of the upper peripheral wall ofthe outer pot and the outer side of the peripheral wall of the inner pot is the air overflowing chamber; the air overflowing chamber is provided with a temperature-sensing drain tap device which is anormal opened drain tap; and when the steam temperature reaches a preset actuating temperature, the drain tap is closed. A method for controlling the full automatic low-pressure quick-cooking pot with the air overflowing chamber comprises: controlling an electric heater according to signals of a temperature sensor in the air overflowing chamber; switching off the electric heater when the vapor temperature reaches a preset upper limit cooking temperature; switching on the electric heater to heat when the vapor temperature reduces to a lower limit cooking temperature; controlling the vapor temperature in a cooking temperature range; making a timing device start to time when the vapor temperature reaches a preset temperature; and stopping the cooking procedure and starting the heat-preserving procedure when the timing device finishes timing.

Description

Low-pressure instant cooker with air overflow chamber and control method thereof technical field The invention relates to the technical field of pressure cookers, and relates to a low-pressure instant cooker with an air overflow chamber. By utilizing the characteristic that the density of air is greater than that of water vapor, the air in the pot is released from the exhaust valve device in the air overflow chamber at the initial stage of cooking. Prioritize the discharge of the pot body to ensure that the instant pot can achieve the high-temperature cooking effect of the instant pot at a low pressure state. A temperature sensor is also installed in the air overflow chamber to control the cooking program according to the steam temperature, and automatically adjust the cooking temperature during the cooking process. It is limited within a certain temperature range and automatically enters a safe heat preservation state after the cooking process is completed. Background techn...

Problems solved by technology

But these technical schemes that improve the safety of pressure cooker still adopt the method that general pressure cooker utilizes pressure valve to control the cooking temperature basically, therefore all can not exempt the problem that needs personnel to intervene, a kind of full-automatic pressure cooker that does not need personnel to intervene will help It can be expected that it will be popular for improving the convenience and safety of the pressure cooker.

Although there are many automated cooking equipment on the market, such as automated rice cookers, automated microwave ovens, automated kettles, automated ovens, and automated bread machines, the pressure cooker that utilizes a pressure valve to control the cooking temperature is not easy to automate. failed to achieve
