Abstract:
A kitchen ventilator, comprising:a hood structure having upper, lower, front and back sides at least partially defining an interior of the ventilator, and an air inlet slot; and a multi-position damper baffle movably positioned adjacent the air inlet slot for movement between: (i) an exhaust cycle position in which the damper baffle angles inward and downward from the air inlet slot such that exhaust air flows into the air inlet slot, downward and around a free end of the damper baffle, and upward to an exhaust outlet; (ii) a wash cycle position in which the free end of the damper baffle is rotated in a first direction toward the air inlet slot for preventing air from entering through the slot and for preventing fluid from escaping through the slot; and (iii) a fire cycle position in which the free end of the damper baffle is rotated in a second direction away from the air inlet slot and adjacent an interior portion of the ventilator to divide the ventilator into an upper section and a lower section, wherein the damper baffle prevents air flow into the upper section and also forms a barrier permitting liquid to be retained within the upper section.
