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.

Abstract: A range hood (2) mounted above a kitchen range (4) includes one or more storage shelves (6, 8) in the hood. An adjustable tilt-out front panel (22) is adaptable to include openable doors (24) for accessing the shelves, and is operated by a user between a position flush with adjacent cabinetry (20) or the like, and an extended position increasing the vapor collection area above the range. A gravity operated baffle (30) maintains integrity of the collection area liner by covering the additional collection area when the front panel is in the tilted-out position or any position inbetween. The housing (14) for the hood has an upper portion (16) and a lower depending portion (18) adjustably mounted to the upper portion to provide an adjustable overall vertical height. A hood mounting system provides built-in three dimensional adjustment and allows an installer to restrict adjustments to a single plane at a time for final fine tuning adjustment.

Abstract: A ventilation fan structure has a fan blade-motor portion and a shroud portion independently affixable to the ceiling to reduce noise levels, improve aerodynamic efficiency, and facilitate installation. A mounting member is affixable to ceiling joists, one of which spans an opening in the ceiling for the fan structure. The drive motor and associated fan blades are mounted on the mounting member. The shroud surrounds the ceiling opening and embraces the fan blades. The mounting member extends through the shroud in its attachment to the joists.

Abstract: A mounting device for securing a range hood beneath a soffit having a framing member fastened to a wall. The device has an elongated mounting plate suitable for being secured along and to the framing member. A pair of hangers depend from the mounting plate and are connected thereto at spaced locations along the mounting plate. The hangers secure the range hood to the mounting device.
