Problems solved by technology

[0002] Range hoods in the related art usually use the method of temperature limit to judge whether the cooking equipment is off. If the time is too long, the range hood cannot be turned off in time, which wastes energy; when the temperature limit is large, the range hood cannot recognize that the cooking equipment is off or on low heat

Abstract

The invention discloses a range hood and a control method and system thereof as well as a fire shutdown detection method and device. The control method comprises: acquiring an actual cooking temperature of cooking equipment in real time; acquiring a relative temperature between the current actual cooking temperature of the cooking equipment and a reference temperature, and generating a relative temperature change curve according to the relative temperature, wherein the relative temperature change curve is continuously divided into a plurality of curve segments; acquiring a temperature change tendency curve corresponding to each curve segment; and judging whether the fire on the cooking equipment is shut down according to a slope of the temperature change tendency curve corresponding to each curve segment. Therefore, the fire shutdown of the cooking equipment can be accurately identified, the judging efficiency of the fire shutdown of the cooking equipment can be improved, misjudgment caused by covering a pan can be avoided, energy resources can be effectively saved, and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of electrical appliances, in particular to a method for detecting fire off of cooking equipment, a non-transitory computer-readable storage medium, a method for controlling range hoods, a device for detecting fire off of cooking equipment, a A control system for a range hood, a range hood, another range hood and yet another range hood. Background technique [0002] Range hoods in the related art usually use the method of temperature limit to judge whether the cooking equipment is off. If the time is too long, the range hood cannot be turned off in time, which wastes energy; when the temperature limit is large, the range hood cannot recognize that the cooking equipment is off or on low heat. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the first object of the present invention is to ...
