Intelligent range hood and control method for same

Abstract

The invention discloses an intelligent range hood which comprises an enclosure, a fan device and an intelligent control system, and the intelligent range hood is characterized in that the intelligent control system comprises a sound acquisition unit, a sound identification unit, a starting control unit, a cooking sound output control unit and a power control unit. Compared with the prior art, the intelligent range hood disclosed by the invention has the advantages that various environment sounds in a kitchen are detected by analyzing the sounds in the kitchen, so that the range hood can judge whether the sounds are made in a cooking process and determine the level of the lampblack quantity corresponding to the cooking sounds; start or stop of the range hood is set and the rotating speed of a fan is adjusted according to the level of the lampblack quantity, so that the aim of intelligently controlling the range hood is fulfilled; control on the range hood is realized by a sound identification technology, so that the execution cost is relatively low; the phenomenon that detection equipment fails in working or the sensitivity of the detection equipment is reduced because of the influence and the pollution of smoke is unlikely to occur; reliable work of the range hood can be guaranteed, and the service life of the range hood is prolonged.

Description

technical field [0001] The invention relates to an intelligent range hood and a control method for the range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment and has become an indispensable kitchen equipment for modern families. At present, after more than 20 years of development in China, range hoods have developed greatly in terms of installation methods and appearance structures. The operation and control methods have also changed from traditional mechanical switches and touch switches to smoke stove linkage. intelligent control. [0003] However, the cooker hood in the range hood linkage mode can only control the corresponding speed of the range hood according to the firepower of the cooker, but not according to the cooking process such as putting in vegetables after the oil temperature rises, stir frying, covering the pot, and picking up the lid. Intelligent adjustments can be made by waiting for changes i...
