ABSTRACT:
An air ventilation and washing system for extracting noxious or other impure air, such as is present above the cooking surface of a stove having automatically activated electrical and mechanical fire control apparatus selectively responsive to changes in temperature is disclosed. The air ventilation system has a hood structure providing a make-up air distribution plenum through which air is distributed and pressurized for equal distribution of make-up air along the length of the hood structure. A vortex baffle is provided in the hood between a make-up air cavity and an exhaust cavity to cause efficient mixing of room air and make-up air from the exterior, while protecting personnel from exposure to the exterior make-up air, and a vortex chamber causes the mixing of the make-up air and room air with contaminated air from the stove.
