Inventors: Kuechler, Irvin R.;
Assignee: Vent-Cair, Inc. (San Bernardino, CA)
Primary Examiner: Byers, Jr.; Nile C.
Assistant Examiner:
Attorney, Agent or Firm:
A grease hood and plenum apparatus is mounted at the ceiling of a restaurant kitchen, and incorporates grease filters and also means to direct make-up air toward such filters. The make-up air passes through a capture chamber the bottom of which is open for reception of fumes from a cooking appliance disposed in the kitchen. An extended exhaust plenum chamber projects upwardly from the hood to draw air and fumes through the filters, and a supply means extends upwardly from the hood to supply make-up air thereto. Blower means deliver make-up air to the supply means and also draw air and fumes from the extended exhaust plenum. The kitchen ceiling has an opening or hole sized and shaped to receive downwardly the grease hood in premanufactured condition, and means are provided to support the greaee hood at the opening and at least partially below the level of the ceiling so that fumes may pass upwardly into the capture chamber. In accordance with the method, the unitary smoke-hood and plenum construction is substantially completed at the factory and then is easily and unitarily installed at the job site by dropping it into the hole or opening in the kitchen ceiling or roof. The hood is supported in spaced relationship above a cooking appliance in the kitchen, and the hole is closed to prevent ingress of water. |
