Example Embodiment

[0012] The anti-dry burning control method of the cooker of the present invention will be further described below.

[0013] The invention is a further improvement on the basis of the existing cooker with temperature detection and display. First, the temperature sensing device of the cooker senses the temperature of the cooker when it is working, and sends the temperature value to the controller of the cooker. When the temperature reaches the set initial temperature value (such as 90°C or 100°C), the process starts judge. At this time, the controller of the cooker compares the difference between the last temperature value detected by the temperature sensor and the temperature value detected this time at regular intervals (such as 20 seconds or 30 seconds or another set time), Through the analysis of the chip in the controller, if the difference exceeds the preset difference (such as 20°C or other values), it can be judged that the cooker is in a dry state; if the difference is...

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...
