ABSTRACT:
A ventilator for cooking units particularly of the kind having a forwardly disposed cooking area and a rearwardly disposed, upstanding flue, as for exhausting of combustion products. The ventilator comprises a free-standing floor-supported hood of rectangular box shape and opens forward and downward to receive the cooking unit removably therein. The hood is formed by boxlike inner and outer shells opening forwardly and downwardly with their top, back and opposite side panels spaced to define a single continuous air flow space therebetween. The air flow space is closed except for an inlet adjacent the rear of the hood and an outlet comprising an inverted U-shaped slot disposed near and extending along the front edges of the top and side panels of the inner shell to face into the cooking area and having a pair of flow directing louvers extending therealong. A U-shaped perforated baffle between the shells separates the front and rear parts of the air space. An exhaust stack communicates with the upper rear portion of the inner shell. A substantially J-shape member extending the width of the inner shell below the exhaust stack on the one hand supports filters facing down and forward toward the cooking area for removing cooking fumes therefrom, and on the other hand, is spaced by a downwardly flaring bypass or slot from the rear panel of the inner shell to deflect exhaust flow from the cooking unit flue, positioned immediately therebeneath, to the exhaust stack without going through the filter.
