Abstract

The invention discloses a multifunctional automatic range hood control system, which is characterized by being mainly formed by a center processor, a power supply, an A/D analog-digital converter, a motor, an alarm, a smoke sensor, a three-terminal voltage stabilizing filter circuit, a lowpass filtering amplifying circuit and a trilinear buffering driving circuit, wherein the A/D analog-digital converter, the motor and the alarm are all connected with the center processor; the smoke sensor is connected with the A/D analog-digital converter; the three-terminal voltage stabilizing filter circuit is connected in series between the power supply and the center processor; the lowpass filtering amplifying circuit is connected in series between the smoke sensor and the A/D analog-digital converter; and the buffering circuit is connected with the driving circuit. The multifunctional automatic range hood control system can accurately collect the concentration value of oil smoke, and accurately control the range hood to automatically turn on or off, thus providing a good living environment for people.

Description

technical field [0001] The invention relates to a control system for a range hood, in particular to a multifunctional automatic 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 accor...
