Abstract

A device and method for cleaning fans in range or stove hoods by spraying steam onto the fan impeller area on which soot and cooking fumes condense to clean the impeller and wash the accumulated condensates down a drain. By using steam above atmospheric pressure as the cleaning fluid, the device uses significantly less water that other devices that spray water or an aqueous solution to clean the fan blades.

RELATED APPLICATIONS

[0001] This application is based on U.S. patent application Ser. No. 11 / 600,469, filed 16 Nov. 2006, which application is based on provisional application 60 / 772,182, filed Feb. 10, 2006, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] This invention relates to a system for continuously cleaning fans operating in a ventilation hood for a stove or other cooking device.

[0003] Kitchen vent or exhaust systems are commonly used to remove steam, odors, and other airborne vapors resulting from cooking on stoves. The exhaust systems often include grease filters to capture grease carried by the airborne vapors. For homes and smaller establishments, the most common is an up draft system utilizing a hood covering a portion or all of the stove burners to capture the rising air. The hood is attached to the wall, or in the case of a kitchen island, is suspended from the ceiling. Conventional vent hoods typically are cone shape...
