Problems solved by technology

This method has the disadvantage of inaccurate detection, especially since water has different boiling points in areas with different altitudes, so the electric heating cooking utensils suitable for a certain area are often used in another area with a different altitude. It is difficult to obtain the ideal cooking effect due to the inability to accurately judge the boiling state of the items in the pot, or the electric heating cooking utensils must be adjusted according to the boiling point of the water in the area before use to obtain the ideal cooking effect. The applicability of the appliance is poor and it is inconvenient to use

Embodiment 1

[0019] The detection method for the boiling of the articles in the pot includes the following steps: (1) the microprocessor resets the value of the comparison times storage; (2) the temperature sensor detects the temperature of the pot body, and transmits the detected temperature value to the microprocessor. Processor; (3) The microprocessor calculates the temperature change rate according to the detected temperature value, and compares the temperature change rate with the preset value; (4) When the temperature change rate is less than the preset value, the microprocessor Add one to the value of the comparison times storage; when the temperature change rate is greater than the preset value, the microprocessor will clear the value of the comparison times storage; (5) If the value of the comparison times storage is less than the comparison times preset value , then go to step (2); if the value of the comparison times storage is equal to the comparison times preset value, then the...

Abstract

The disclosed detection method for boiling in an electric boiler comprises: (1) obtaining boiler temperature and variation rate; (2) comparing the rate with pre-set value; (3) if the variation less than pre-set value for a space, deciding it is boiling. Wherein, the detection device comprises: a thermistor as temperature sensor, a MPU, a capacitor and its charge / discharge circuit and level detection circuit all connected to the MPU. This invention is free to height above sea level, and benefit to obtain ideal cook effect.

Description

technical field [0001] The invention relates to an electric heating cooking appliance, in particular to a detection method for the boiling of items in a pot in the electric heating cooking appliance, and a detection device using the detection method. Background technique [0002] When the existing electric heating cooking utensils (including electric heating pot, induction cooker, electric kettle, etc.) When it is detected that the temperature of the pot body reaches a certain set value (usually the value is the boiling point), it is judged that the contents in the pot are in a boiling state. This method has the disadvantage of inaccurate detection, especially since water has different boiling points in areas with different altitudes, so when an electric cooking appliance suitable for a certain area is used in another area with a different altitude, it will often fail. It is difficult to obtain the ideal cooking effect due to the inability to accurately judge the boiling st...
