Kitchen ventilator, control method and system thereof, and fire lighting detection method and apparatus

Abstract

The invention discloses a kitchen ventilator, control method and system thereof, and fire lighting detection method and apparatus. The control method includes the following steps: acquiring actual cooking temperature of a cooking device in real time; acquiring relative temperature between the present actual cooking temperature and a basic temperature of the cooking device and generating a relativetemperature change curve according to the relative temperature; dividing the relative temperature change curve continuously into a plurality of curve sections, and acquiring a temperature change tendency curve of each curve section; according to the slope of the temperature change tendency curve of each curve section, determining whether the cooking device lights fire or not, thereby accurately recognizing the fire lighting status of the cooking device according to the slopes of the temperature change tendency curves. The method can effectively avoid mis-determination due to human body temperature and increases efficiency of determination of the fire status of the cooking device, thereby improving user experience.

Description

technical field [0001] The present invention relates to the technical field of electrical appliances, in particular to a fire detection method for cooking equipment, a non-transitory computer-readable storage medium, a control method for range hoods, a fire detection device for cooking equipment, and an oil suction device. A control system for a hood, a range hood, another range hood and yet another range hood. Background technique [0002] Range hoods in the related art usually use the temperature limit method to determine whether the cooking equipment is on fire. However, the problem in the related technology is that when the temperature limit value is set small, the temperature of the human body is likely to cause misoperation of the range hood. When it is larger, the range hood will be triggered after the cooking equipment is turned on for a long time, especially when cooking on a low fire, the range hood will take longer to start, which will affect the user experience. ...

Problems solved by technology

[0002] Range hoods in the related art usually use the temperature limit method to judge whether the cooking equipment is on fire. However, the problem in the related technology is that when the temperature limit value is set small, the temperature of the human body may easily cause the range hood to misoperate. When it is larger, the range hood will be triggered after the cooking equipment is turned on for a long time, especially when cooking on a low fire, the range hood will take longer to start, which will affect the user experience
