Problems solved by technology

However, when the cooking pot is covered or the cooking pot is turned from high heat to low heat, the range hood is likely to misjudge that the cooking equipment is turned off, so that the range hood is likely to be turned off by mistake.

Abstract

The invention discloses a fire turn-off detection method and device, a range hood and a storage medium. The fire turn-off detection method comprises the following steps of acquiring a temperature change curve of cooking equipment; obtaining the slope of a temperature trend line corresponding to the temperature change curve according to the temperature change curve; acquiring a characteristic ratioof the temperature trend line according to the slope of the temperature trend line; judging whether the characteristic ratio of the temperature trend line is smaller than a preset characteristic ratio or not within a preset duration, and accumulating the judgment times; enabling the characteristic ratio of the accumulated temperature trend line to be smaller than the detection frequency of the preset characteristic ratio; and under the condition that the judgment frequency is greater than the first preset frequency and the detection frequency is greater than the second preset frequency, determining that the cooking equipment is turned off. According to the fire turn-off detection method, the distinguishing performance of the cooking equipment in the soft fire state and the fire turn-off state can be improved, and the fire turn-off detection time of the cooking equipment is shortened, so that whether the cooking equipment is in the soft fire state or the fire turn-off state is accurately judged, misoperation is reduced, and misoperation of the cooking equipment in the soft fire state is prevented.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, and more specifically, to a fire-off detection method and device for cooking equipment, a range hood and a storage medium. Background technique [0002] In related technologies, with the development of sensing technology and communication technology, the development of intelligent technology for kitchen appliances is becoming more and more mature. Among them, the intelligent range hood can detect the working status of the cooking equipment under the range hood, and automatically control the opening, adjusting the wind speed, closing and other operations. In the prior art, the method of temperature limit or temperature change rate is generally used to judge whether the cooking equipment is turned off. However, when the cooking pot is covered or the cooking pot is turned from high heat to low heat, the range hood is likely to misjudge that the cooking equipment is t...
