Range hood, its control method and system, and fire detection method and device

Abstract

The invention discloses a range hood, a control method and system thereof, and an ignition detection method and device. The real-time cooking temperature of cooking equipment is obtained in real time;the relative temperature between the current actual temperature of the cooking equipment and the reference temperature is obtained, and a relative temperature curve is generated according to the relative temperature and is continuously divided into a plurality of curve sections; the temperature change rate of each curve section is obtained; according to the temperature change rate of each curve section, whether the cooking equipment is ignited is judged, thus ignition of the cooking equipment can be accurately recognized through the temperature change rates, error judgment influenced by bodytemperature is avoided effectively, ignition judgment efficiency of the cooking equipment is improved, and the experience of a user is improved.

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 of a range hood and a 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. Contents of the invention [0003] T...
