Abstract
An exhaust fan, an exhaust duct through which a discharged gas flows and a filter which is provided in the exhaust duct are included. A curved portion is provided in the exhaust duct, and the filter is provided on a downstream side in a direction of flow of the gas with respect to the curved portion. On an inside wall of the curved portion of the exhaust duct on an outer side in a radial direction, a first flow control member that uniformizes the amount of the gas flowing through the filter is provided so as to be perpendicular to the shaft of the curved portion, and a space is formed between the first flow control member and an inside wall of the curved portion on an inner side in the radial direction.
