Abstract:
An exhaust fan for use in bathrooms or similar areas has a generally rectangular fan housing formed from two independent structural members to reduce manufacturing waste and decrease production cost. The fan housing includes a receptacle panel that can be installed and removed from within the housing without additional tools. The fan housing includes two series of spaced view holes formed in its back wall such that during installation of the exhaust fan, the installer can view the ceiling joist to correctly position the fan housing relative to the bottom surface of the joist. The back wall of the fan housing also includes a pair of bend down tabs that can be placed in contact with the bottom surface of the joist to correctly position the bottom edge of the fan housing the required distance from the joist to accommodate the most common drywall thickness. The fan wheel contained within the fan housing includes a mounting hub having an expanded diameter insertion portion formed on its central bore to receive drive shaft of driving motor of the exhaust fan.

Abstract:
A ventilator for a cooking unit located in a counter has a housing suitable for mounting beneath the counter. A vent member moves in a generally vertical direction with respect to the housing between a retracted position in which said vent member is flush with the counter and an extended position in which the vent extends above the counter adjacent to the cooking unit. The vent member is in fluid communication with said housing. A blower is coupled to said housing for drawing cooking effluents produced at the cooking unit into said vent member, downwardly through said vent member into said housing, and discharging same from said ventilator. A motor is mounted on the housing for moving a roller in an arcuate path. The roller engages a follower surface mounted on the vent such that travel of the roller along the follower surface drives the vent to the extended position. The vent moves to the retracted position by its own weight, with such movement being restrained by the engagement between the roller and the drive surface.
