Range exhaust cleaning system and method
First Claim
1. A cleaning system for a cooking range exhaust including a range hood having a backsplash and optionally an exhaust flue, the cleaning system comprising:
- a fluid delivery system constructed for at least partial placement within the cooking range exhaust, the fluid delivery system including,a non-rotating hood spray conduit constructed for placement within the range hood and longitudinally traversing a portion of the backsplash, the hood spray conduit comprising a plurality of spray openings for directing a degreasing composition to an interior surface of the backsplash;
a non-rotating flue spray conduit constructed for placement within or outside the flue, the flue spray conduit comprising or couplable to a plurality of spray openings for directing the degreasing composition to an interior surface of the flue; and
a fan subsystem conduit constructed for placement within a fan subsystem located vertically above a top end portion of the flue spray conduit, the fan subsystem conduit comprising a plurality of spray openings for directing the degreasing composition to an interior surface of the fan subsystem, wherein the fan subsystem conduit includes a plurality of bends or couplings, each bend or coupling forming an angle greater than 90 degrees; and
a pump system constructed for conveying the degreasing composition from a degreasing composition source and through the fluid delivery system.

Abstract
A cleaning system for a cooking range exhaust having a range hood, a backsplash, and an exhaust flue for exhausting cooking effluent is disclosed. The cleaning system can include a fluid delivery system constructed for partial placement within the cooking range exhaust. The fluid delivery system can include a hood spray conduit constructed for placement within the hood and comprising spray openings for directing a degreasing composition to the backsplash. The fluid delivery system can also include a flue spray conduit constructed for placement within or outside the exhaust flue and comprising at least one spray opening for directing the degreasing composition to an interior surface of the flue. The cleaning system can include a pump system constructed for conveying the degreasing composition from a degreasing composition source and through the fluid delivery system. A method of cleaning a cooking range exhaust and a self-cleaning exhaust system are also disclosed.
