PROBLEM TO BE SOLVED: To facilitate mounting and cleaning of a filter by a method wherein a feed box connected to a feed duct communicated to the outside of a house is placed on the top plate of a hood body, and the discharge port of the feed box is connected to the inflow port of the gollow front plate of the hood body, and a suction filter is removable mounted on the inflow port. SOLUTION: A feed box 8 is placed in the upper surface of a top plate 1a of a good body 1 and a multublade fan 8b is contained in a casing 8a. A suction port 8c of the casing 8a is connected to an air feed duct 9 communicated with the outdoors, and a delivery port 8d is joined with an inflow port 14 of a hollow front plate 3 attached to the front opening part of the hood body 1. The hollow front plate 3 is formed such that a front plate 3a joined with the front opening part of the hood body 1 and frieze board part 3b vertically arranged between the top plate 1a and a ceiling are integrally formed. At an internal part, a partition plate 15 is mounted in a state to be positioned on the line of the lower hole edge of the inflow port 14, and a feed filter 16 is removably supported from an insertion port 17 opened to the partition plate 15 to a spot situated downstream from the inflow port 14. |
