Control method for preventing outburst in quick open of electric pressure cooking saucepan

Abstract

The invention relates to a control method for preventing outburst in quick open of an electric pressure cooking saucepan. In the electric pressure cooking saucepan, a control program which prevents porridge from overflowing or spurting in a quick opening process is arranged in a memory unit, and controls the electric pressure cooking saucepan to enter a heat phase, a boiling keeping phase, a first pressure maintaining phase and a second pressure maintaining phase according to a temperature signal acquired by a temperature measurement device and a time signal acquired by a timing unit. In the method, pressure maintaining is divided into two working processes, wherein the first pressure maintaining phase is to lead food in the saucepan to absorb enough heat to achieve the effect of reasonably cooking; and the second pressure maintaining phase is to lead the pressure in the saucepan to be cooled naturally, so that a proper pressure point is reached, and an exhaust device can be opened to realize normal exhaust. Therefore, safety of a user is guaranteed, the effect of quickly opening is achieved, and the problems of environmental pollution and body injury caused by porridge overflowing or spurting in the forcible opening process of a traditional pressure saucepan can be solved.

Description

technical field [0001] The invention belongs to the technical field of electric pressure cooker control, and in particular relates to a control method for preventing overflow of the electric pressure cooker during the rapid opening process. Background technique [0002] Now the pressure cooker is accepted by consumers for its fast cooking, and it will have a very good development momentum in the future. However, there is another shortcoming with it that the lid cannot be opened for a long time, especially when cooking porridge, and sometimes the time of opening the lid is longer than the cooking time. In order to allow it to open the cover quickly, the electromagnet is commonly used to push the iron ball and the manual push rod to push the exhaust valve to exhaust the air so that it can be quickly opened. When cooking porridge or soup, if the air is exhausted directly, the porridge or soup will be sprayed, which is easy to burn the user, and the sprayed liquid will splash ...

AI Technical Summary

Problems solved by technology

When cooking porridge or soup, if the exhaust is exhausted directly, the porridge or soup will be sprayed, which is easy to burn the user, and the sprayed liquid will splash on the pot cover or table.

[0003] figure 1 Among them, the natural pressure-reducing cooking process of existing electric pressure cooker products includes a heating stage, a boiling stage, a pressure-holding stage and a natural cooling stage after cooking. The natural cooling time is very long, and the cover cannot be opened for a long time.
