  • Patent number: 4700688
    Abstract: In a ventilating hood generally for use in conjunction with a heating apparatus, such as a cooker, a housing incorporates both a diverter and a rear support, the two of which join to segregate the incoming air through a supply conduit from the outgoing air traversing through a support arranged filter and into an exhaust outlet. The front wall of the housing, which is spaced from the lower end of the diverter, incorporates a slightly upwardly inclined deflector, which directs substantially all of the air incoming to the hood upwardly and rearwardly directly towards for movement through the filter, and out of the exhaust outlet, and since the air is generally unencumbered by any structure in the path of its flow, it moves in a rather parallel course with the arranged diverter, and rapidly exits carrying the entrained fumes therewith significantly reducing the BTU requirements for operation of this hood.
    Type: Grant
    Filed: October 10, 1986
    Date of Patent: October 20, 1987
    Assignee: Cambridge Engineering, Inc.
