Abstract

The invention discloses an energy-saving control based on hybrid multiple circuits for a range hood. The energy-saving control system is characterized by being mainly composed of a central processing unit, a power supply, an A / D (analogue / digital) converter, a motor and an alarm which are all connected with the central processing unit, a smoke sensor connected with the A / D converter, a logic gate protection circuit serially connected between the central processing unit and the alarm, a three-terminal voltage-stabilizing and filtering circuit serially connected between the power supply and the central processing unit, and a trilinear buffer and drive circuit serially connected between the central processing unit and the motor. The control system for the intelligent domestic range hood, which is disclosed by the invention, is capable of accurately acquiring a concentration value of lampblack, and accurately controlling the range hood to be automatically turned on or off, thus providing a good living environment for people.

Description

technical field [0001] The invention relates to a range hood control system, in particular to a hybrid multi-circuit energy-saving range hood control system. Background technique [0002] At present, the range hoods produced and sold in China all have key switches for operating the range hoods, but the key switches of such range hoods are prone to problems such as failure and reduced sensitivity during use. Moreover, people often forget to turn off the range hood after use, thus causing a large amount of waste of energy. [0003] Therefore, people are in urgent need of a range hood control system that can control the range hood to automatically open or close according to the concentration of the range hood, so as to meet the requirements of convenience, environmental protection and energy saving. Contents of the invention [0004] The purpose of the present invention is to overcome the defect that the range hood in the prior art cannot be automatically turned on or off ac...
