Abstract
The invention relates to a ventilator assembly and method for removing kitchen exhaust flumes entrained in a moving air stream from an, area surrounding a cooking unit. A roof-top blower moves the air stream from the cooking area through an air duct to the atmosphere. An overhanging hood defines a ventilation opening located above the cooking unit. One or more air vents are formed in a top wall of the hood and communicate with the air duct. The hood back panel has upper and lower longitudinal flanges, the lower flanges of which nests in a wall-mounted underlying first bracket securely earlier mounted on the kitchen side wall, while the hood upper flange is overlapped and retained by a second bracket holding the hood in an upright functional position.
Claims9
A ventilator assembly adapted for mounting on a vertical support wall for removing kitchen exhaust fumes and entrained in a moving airstream from an area surrounding a cooking unit, including a rooftop blower for moving the airstream through an air duct to the atmosphere, said ventilator assembly comprising:
- (a) an overhanging venting hood defining a ventilation opening located above said cooking unit, said hood including a hood back panel, spaced-apart, two side panels, and a connecting front panel
- (b) at least one planar panel secured vertically to a kitchen bearing wall and adapted to serve as a fixed support upon which the hood back panel of the ventilator assembly is to be fixedly mounted for regular usage;
- (c) one or more air vents formed in the top panel of said hood which are in communication with the air duct;
- (d) the back panel being provided with a lower and an upper substantially linear edges which abut the bearing wall;
- (e) an underlying elongate first channel member, having an open channel configuration, when seen in vertical cross section, and being fixedly mounted on the planar panel, while supporting a lower first flange of the hood back panel;
- (f) an overlying second top channel member having a wall offset configuration, when seen in vertical cross section, comprising first and second longitudinal segments, with the depending longitudinal segment thereof adapted to engage and retain an upper second flange of the hood back panel in abutment to the planar panel, and
- (g) a third underlying channel member having an open channel configuration, and directly mounted on the bearing sidewall, while supporting the lower edge of the abutting one planar panel;
- (h) a fourth overlying channel member having an inverted U-shaped open channel configuration, directly, mounted on the bearing sidewall, while supporting the upper edge of the planar panel on the bearing sidewall;
- and
- (i) a fumes filter element positioned transversely within the venting hood and adapted for removing fumes from the moving air stream during the course of venting hood utilization;
A method of removing kitchen exhaust fumes entrained in moving air stream from an area surrounding a cooking unit, comprising the steps of:
- (a) mounting a blower means outside of the cooking area and in communication with the atmosphere for moving air from the cooking area to the atmosphere;
- (b) mounting an elongate first linear bracket on the sidewall selected to support an overhanging hood located to just above the cooking area, said first channel being provided with an open channel adapted to receive an elongate lower flange which is integral with the overlying hood;
- (c) mounting the hood adjacent the sidewall along its lower flange which lower flange engages an open channel, first bracket as the initial hood position;
- (d) rotating the linearly supported hood into its normal upright second position adjacent the support wall while retaining same by manual means in that second position;
- (e) mounting an elongate second linear bracket on the sidewall so as to overlap an upper flange which is integral with the upright hood;
- (f) securing the second bracket to the sidewall with conventional fastening means;
- and,
- (g) then removing the manual means initially used to retain the hood upright.
