Title: RANGE HOOD
Abstract:
The purpose of the present invention is to reduce the possibility that noise is generated in a range hood in which a filter is caused to rotate. Provided is a range hood (1) comprising: a fan (4) for generating air flow; a filter (10) that is on the flow path of the air flow and exists on the upstream side of the fan, and has holes for allowing the air flow to pass therethrough; an electric motor (20) for rotating the filter; a control unit (30) that executes control by which the electric motor is caused to rotate at at least two speeds, specifically a first rotation speed and a second rotation speed faster than the first rotation speed; and a cooking state monitoring unit (40) for monitoring the cooking state of a cooking device. According to the cooking state monitored by the cooking state monitoring unit, the control unit controls the rotation speed of the electric motor, using the first rotation speed and the second rotation speed.
