基于ATmega 16L的变频节能抽油烟机设计

The Energy Conservation Designs of Kitchen Fan with Atmega16L and Frequency Inverter

本文分析了以往传统的固定频率手动式抽油烟机的不足,提出了一种由气敏传感器电路与ATmega 16L单片机控制和传统吸油烟机相配合的变频式吸油烟机装置设计。本装置通过由传感器将油烟量转变为电压(或电流)电信号送单片机处理。处理后由单片机控制电机转速,实现变频调速的目的。可广泛应用于家庭厨室,解放人力并能最大限度节省能源。

This article has analyzed the former traditional fixed frequency manual-like kitchen fan＇s insufficiency and presents mainly about a kind of machine with sensor that can absorb the smoke while you are cooking. It is controlled by a gas sense circuit and a singlechip,cooperaling with a traditional range hood that we often use. This device changes gas into electric signal through the sense circuit. Then the signal is sent to the single--chip. After that, the single--chip can control the rotary speed realizing frequency inversion. This de vice can be widely used in kitchens. It is very convenient and can save the energy to a maximum degree.
