Method, processing unit and device for detecting dry burning of cooking utensil and storage medium

Abstract

The invention relates to the field of kitchen utensils, and discloses a method and device for detecting dry burning of a cooking utensil. The method comprises the steps that after the cooking utensilis switched on, the temperature of a pot is detected; a first temperature variation rate is determined according to the detected temperature; whether or not the first temperature enters a preset rangeis determined; whether or not the cooking utensil is at a stable heating state is determined under the condition that it is determined that the first temperature variation rate enters the preset range; after it is detected that the cooking utensil is at the stable heating state, the temperature is continually detected, and a second temperature variation rate is determined according to the detected temperature; whether or not the second temperature is greater than a preset value is judged, wherein the preset value is equal to or greater than the upper limit value of the preset range; whether or not the cooking utensil is at a dry burning state is determined under the condition that the second temperature variation rate is greater than the preset value. By means of the method, the damage ofthe pot due to the fact that dry burning is not timely judged, and therefore user experience is improved.

Description

technical field [0001] The present invention relates to the field of kitchen utensils, in particular to a method, processor, device and storage medium for detecting dry cooking of cooking utensils. Background technique [0002] At present, in the case of more and more emphasis on safety, more and more cooking utensils use anti-dry technology. In the related art, for a gas stove, it is common to install a temperature sensor in the center of the burner of the gas stove, and the temperature sensor can touch the bottom of the heated pot. When the pot is dry-burned, the temperature will rise. When it is detected that the temperature rises to the predetermined dry-burning temperature, a signal will be sent to the control center of the gas stove, and the control center will cut off the gas source to end the dry-burning. However, the above-mentioned dry-boiling prevention solution in the related art has the problem of not being timely enough to judge dry-boiling when it is aimed at...

Problems solved by technology

However, the above-mentioned anti-dry-burning solution in the related art has the problem of not judging that the dry-burning is not timely enough when targeting special pots and utensils.

For example, in application scenarios such as steaming and soup making with cooking utensils, the pot is often dry-burned because the user leaves or forgets halfway. When the heated pot is a casserole, due to the thickness of the casserole itself and the The reason is that after the occurrence of dry burning, the temperature of the metal pan does not heat up as quickly, so the control center may judge the occurrence of dry burning and cut off the fire after a long time after the casserole is dry, which is easy to burn the casserole
