Anti-dry cooker

Abstract

The invention provides a dry burning resistant stove. The stove comprises a weighing device and a control device, wherein the weighing device is arranged below a deck plate for detecting total weightof a stove and materials inside the stove above a stovetop burner and / or vibrating accelerated speed of the stove; and the control device is in circuit connection with a detecting part and is configured to close or open a fuel gas switch of the stovetop burner according to total weight changes of the stove and the materials inside the stove as well as vibrating accelerated speed size of the stove.Specifically, when accelerated speed of the stove and the materials is smaller than an accelerated speed threshold value and weight reduction speed of the stove and the materials is greater than a weight reduction speed threshold value, dry burning is determined. According to the dry burning resistant stove provided by the invention, weight and vibrating accelerated speed are used to comprehensively judge whether dry burning occurs or not, so that judging results are more accurate, and a time point of closing the fuel gas switch can be precisely determined, and therefore, the condition that the fuel gas switch is automatically closed while dry burning occurs or food is not cooked thoroughly is avoided.

Description

technical field [0001] The invention relates to kitchen utensils, in particular to an anti-dry cooking stove. 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 topic. [0003] In order to...

AI Technical Summary

Problems solved by technology

However, due to the different cooking methods of users each time, the temperature thresholds for dry burning in different situations are not the same, and cannot be generalized

However, the above-mentioned gas stove generally only sets a temperature threshold point, which will result in inaccurate judgment of the time point when the gas stove is dry-burned.

For example, when the user is frying food, the temperature of the cooker is higher than that of other cooking modes. In this case, the gas stove may automatically cut off the gas switch before it actually burns dry, resulting in the food not being cooked; Or when the user is cooking food, the temperature of the cooker is lower than that of other cooking modes. In this case, dry burning may have occurred, and the gas stove cannot cut off the gas switch in time, causing safety hazards
