Dry burning prevention controlling method for cooker and cooker applying same

Abstract

The invention discloses a dry burning prevention controlling method for a cooker. The method comprises the following steps that: a temperature sensing device in the cooker senses the temperature of the cooker, and transmits temperature signals to a controller in the cooker, and the controller judges whether the cooker is in a dry burning state according to the temperature rise difference in unit time and sends signals indicating that whether dry burning exists. According to the dry burning prevention controlling method and the corresponding cooker, the controller judges the value of temperature change in the unit time according to the temperature of the cooker sensed by the temperature sensing device; and if the temperature sharply rises in the unit time, the cooker is in the dry burning state, then the controller sends the dry burning signals to prompt a user of carrying out proper operation through voice or sends the signals to a heat source, and a controller of the heat source controls the heat source to stop working, so that potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the field of intelligent control of cooking utensils, in particular, to a method for controlling dry burning of cooking utensils and cooking utensils using the method. Background technique [0002] General cooking utensils in the market do not have anti-dry function. Some cooking utensils have the function of temperature display, which generally senses the temperature of the pot body by setting a temperature probe on the bottom or wall of the pot, and then transmits the temperature signal to the circuit board in the handle of the cooker, converts it into a digital signal, and passes the handle The display screen on the top will display the temperature signal, so as to prompt the current temperature, which is convenient for the user to perform corresponding operations. For example, a kind of frying pan with temperature display function disclosed in Chinese Patent Publication CN2817672Y. This kind of cooking utensil requires th...

This kind of cooking utensil requires the user to pay attention to the temperature at all times, and judge whether the inside of the cooking utensil is in a dry state according to the experience of use, but cannot be intelligently controlled. Therefore, the accuracy of this judgment is low, which brings inconvenience to the use, and once the user Leaving the cooking utensils, continuous dry burning is likely to cause a fire, and the consequences are disastrous
