Cooking utensil and steam exhaust and pressure reduction control method for same

Abstract

The invention provides a cooking utensil and a steam exhaust and pressure reduction control method for the same. The steam exhaust and pressure reduction control method for the cooking utensil includes judging whether the cooking utensil enters a steam exhaust stage or not; controlling internal currents of a coil or the magnitude and / or directions of voltages at two ends of the coil if the cooking utensil enters the steam exhaust stage, adjusting the intensity of a magnetic field generated by the coil and magnetic field force on a steam exhaust valve, controlling cooking utensil steam channel opening degree of the steam exhaust valve and further controlling the steam exhaust speed of the cooking utensil. The cooking utensil and the steam exhaust and pressure reduction control method for the cooking utensil have the advantages that power-on conditions of the coil can be changed, so that the magnitude and the direction of acting force which is exerted by the coil on the steam exhaust valve can be changed, the opening degree of the steam exhaust valve can be controlled, and the steam exhaust speed can be controlled; steam exhaust and pressure reduction speeds can be increased on the premise that pot spilling is assuredly prevented, and accordingly the steam exhaust and pressure reduction time can be shortened.

Description

technical field [0001] The invention relates to the field of kitchen utensils, and more specifically, to a method for controlling exhaust steam and pressure reduction of a cooking utensil and a cooking utensil. Background technique [0002] At present, the electric pressure cooker industry has adopted a variety of schemes in order to quickly reduce the pressure of the product. [0003] Solution 1: During the cooking process, the solenoid valve is used to intermittently push the exhaust valve to quickly reduce the pressure in the pot. Because the push rod of the solenoid valve has a single stroke, the exhaust valve can only be switched directly between the open and closed states. This kind scheme is when the pressure in the pot is bigger, because the pressure difference between the pressure in the pot and the atmospheric pressure is bigger, when cooking operations such as cooking porridge, it is easy to cause sticky food to be ejected with the high-pressure gas.

Problems solved by technology

This solution has the same problems as the first solution, and the high temperature gas is likely to cause burns to the user

[0005] Therefore, in order to prevent the pot from overflowing, it is usually necessary to cool the electric pressure cooker first (natural cooling, air cooling, water cooling). Steam time is too long
