Abstract

The invention discloses an energy-saving smoke exhaust ventilator based on hybrid multi-circuit treatment. The energy-saving smoke exhaust ventilator based on hybrid multi-circuit treatment is characterized by mainly comprising a central processing unit, an analog/digital (A/D) converter, a motor, an alarm, a display, a power supply, a smoke sensor, an active rectifying, filtering and voltage stabilizing circuit, a signal anti-interference processing circuit and a constant-current source driving circuit, wherein the A/D converter, the motor, the alarm, the display and the power supply are connected with the central processing unit; the smoke sensor is connected with the A/D converter; the active rectifying, filtering and voltage stabilizing circuit is serially connected between the power supply and the central processing unit; the signal anti-interference processing circuit is serially connected between the smoke sensor and the A/D converter; and the constant-current source driving circuit is serially connected between the central processing unit and the motor. A control system of the intelligent domestic smoke exhaust ventilator can accurately acquire a smoke concentration value, accurately controls the smoke exhaust ventilator to be switched on or switched off automatically, and provides a good living environment for people.

Description

Technical field [0001] The invention relates to an energy-saving range hood based on hybrid multi-circuit processing. Background technique [0002] At present, the range hoods produced and sold in China all have key switches to operate the range hoods. However, the key switches of such range hoods are prone to failure and sensitivity reduction during use. Moreover, people often forget to turn off the range hood after use, resulting in a lot of waste of energy. [0003] Therefore, people now urgently need a range hood control system that can control the range hood to automatically turn on or off according to the concentration of the range hood, so as to realize the requirements of convenience, environmental protection and energy saving. Summary of the invention [0004] The purpose of the present invention is to overcome the defect that the range hood in the prior art cannot control the range hood to automatically turn on or off according to the concentration of the lampblack. The p...
