Problems solved by technology

However, due to the hysteresis of the temperature sensor and the plateau effect in the plateau area, the boiling point of the cooked food rises, making the temperature inaccurate, which causes the heater in the pot to continue heating for a period of time after the pressure reaches the set value. time, causing the electric pressure cooker to overflow during cooking

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a pot cover, an electric pressure cooker and an anti-overflow control method. The pot cover comprises a cover body, an exhaust valve core mounted in the cover body, an exhaustvalve body sleeving the upper end of the exhaust valve core, and a hot gas sensing device; a cavity communicating with the outside is disposed in the cover body; ; an exhaust passage extending in an axial direction of the exhaust valve core is disposed in the exhaust valve core; an exhaust hole is formed in the upper end of the exhaust valve core, and an intake hole is formed in the lower end of the exhaust valve core; the hot gas sensing device is disposed in the cavity, is used for sensing hot gas discharged from the exhaust hole, and outputting an overvoltage signal to a control circuit board when the hot gas is sensed so as to adjust a heating program. A trace amount of hot gas discharged from the exhaust hole is sensed timely by the hot gas sensing device, the overvoltage signal is output to the control circuit board, the control circuit can timely adjust the heating program to reduce the pressure of the cooker, and the anti-overflow effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a pot cover, an electric pressure cooker and an anti-overflow control method. Background technique [0002] Exhaust valves are installed on some electric pressure cookers at present, and are used for when the gas pressure in the pot reaches a certain value, the hot gas in the pot is discharged through the exhaust valve. There is a temperature sensor on the pot cover to detect the temperature in the pot. However, due to the hysteresis of the temperature sensor and the plateau effect in the plateau area, the boiling point of the cooked food rises, making the temperature inaccurate, which causes the heater in the pot to continue heating for a period of time after the pressure reaches the set value. time, causing the electric pressure cooker to overflow during cooking. Contents of the invention [0003] The main purpose of the present invention is to provide a pot cover,...
