碩士 === 國立虎尾科技大學 === 電機工程研究所 === 101 === Rang hood is complete idle during the non-cook time, it is a pity. If it is able to use the similar structure of exhaust fan, to add a temperature sensing device with the function of ventilation, which will keep the room at a comfortable temperature and make the machine become a dual-purpose machine. The paper has developed an intelligent DC inverter range hood with the function of ventilation. The temperature sensing element of the range hood will adjust the speed of revolution automatically in accordance with the room temperature changes. It could effectively accomplish the ventilation by the temperature changes and it also has the same multi-segment speed regulation function as the common range hood. In this paper, MCU with the type of dsPIC30F4011 is adopted. The dsPIC30F4011 can perform frequency conversion by motor driving, and coordinated with circuit design to enable this driver to effectively brushless DC motor.
