See full text

An option device for an electrical appliance of the invention is provided with a filter for purifying exhaust air from the electrical appliance, and an electric fan, wherein the air flow resistance in an external air inlet port formed independently of a suction port for sucking exhaust air from the electrical appliance is adjustable. According to this configuration, it is easy to secure balance between the exhaust air flow rate of the electrical appliance and the suction force by the electric fan without variably controlling the rotational speed of the electric fan.
