Anti-dry stove and its control method

Abstract

The invention provides anti-dry-cooking cooking utensils and a control method thereof. The control method comprises the steps that the heating time required that the temperature value of a cooker andobjects being contained in the cooker rises to a threshold temperature is calculated and determined according to the weight of the cooker and the objects being contained in the cooker and the consumption speed; and when the continuous use time of the cooker is greater than the heating time, a fuel gas switch of the cooker is turned off, and the cooker is stopped heating. The control method uses the specific heat capacity formula to calculate the time point at which the temperature value of the cooker and the objects being contained in the cooker reaches the threshold temperature, the gas switch is automatically cut off at this time point to prevent the temperature of the cooker and the objects being contained in the cooker from exceeding the threshold temperature, so that the inner portionof the cooker is effectively prevented from dry cooking, and the use safety of the cooker is improved. The control method avoids to use a temperature sensor to directly detect the surface temperatureof the cooker, overcomes the technical defects of the inaccurate temperature detection of the cooker in the prior art, thereby more accurately determining the time point of occurrence of dry cookingand improving the accuracy of the intelligent control of the anti-dry-cooking cooking utensils.

Description

technical field [0001] The invention relates to kitchen utensils, in particular to an anti-dry cooking stove and a control method thereof. Background technique [0002] A gas stove is a commonly used stove in modern families, which generates an open flame by burning gas to heat or cook food. Such a gas stove is generally provided with a knob on its panel to control the size of the fire and a fire switch, and the user turns on / off the gas stove through the knob. However, in some cases, the user may forget to turn off the gas stove during cooking, and the material in the cooker is heated for a long time, and its liquid boils dry, resulting in a dry burn phenomenon. If the burning continues, it will not only burn the food and cause waste, but in severe cases, it will also cause the temperature of the cooker to be too high, causing a fire. Therefore, in the field of gas stoves, how to intelligently turn off the gas switch to prevent dry burning has become an important research...

AI Technical Summary

Problems solved by technology

However, during the cooking process of the current anti-dry cooker, the temperature sensor is easily affected by the high temperature of the cooker, resulting in inaccurate measurement

Therefore, this will inevitably lead to inaccurate judgment of the time point when dry burning occurs, resulting in errors and affecting the intelligent control of the cooker
