Range hood

The utility model provides an improved range hood. One embodiment of the utility model relates to a range hood which comprises an airflow channel and an electrostatic oil smoke filtering device (8) arranged in the airflow channel, and further comprises an active noise reduction device. The active noise reduction device comprises a microphone (11), a loudspeaker (12) and a control module. The microphone (11) and the loudspeaker (12) are both electrically connected to the control module; and the microphone (11) is positioned at the downstream of the electrostatic oil smoke filtering device (8) along the flowing direction of oil smoke airflow in the airflow channel. Therefore, grease attachment on the microphone can be reduced. 本申请提出一种改进的抽油烟机。本申请一个实施例关于抽油烟机，包括气流通道和设置于所述气流通道内的静电式油烟过滤装置(8)，还包括主动降噪装置；所述主动降噪装置，包括麦克风(11)、扬声器(12)和控制模块；所述麦克风(11)和扬声器(12)，均电连接于所述控制模块；沿所述气流通道内油烟气流的流动方向，所述麦克风(11)位于所述静电式油烟过滤装置(8)的下游。由此，有助于减少麦克风上的油脂附着。
