PROBLEM TO BE SOLVED: To provide a simultaneous supply-exhaust type range hood capable of being connected to a duct in a dimensional range of the range hood even if using an electric sealing shutter having a totally-long joint for connecting it to the duct. SOLUTION: A connection member 32 is used for connecting the duct C1 to an air supply box 3 when mounting the joint. Even if using the totally-long electric sealing shutter B, a portion having an approximately half of the total length of the joint is stored in the air supply box 3. COPYRIGHT: (C)2007,JPO&INPIT
