Abstract
A cleaning head is disclosed for use in a traversing shower system. The cleaning head includes a plurality of directional fluid nozzles for discharging a fluid, each of which is provided along a different direction toward a work surface such that no two directions cross one another between the cleaning head and a working surface.
Claims26
A cleaning head for use in a traversing shower system, said cleaning head comprising a plurality of directional liquid nozzles for discharging a liquid onto a working surface, each directional liquid nozzle being provided along a different direction toward the working surface such that no two directions cross one another between the cleaning head and the working surface,
- wherein the plurality of directional liquid nozzles includes a first directional liquid nozzle in a machine direction of the working surface, a second directional liquid nozzle opposite the machine direction of the working surface, a third directional liquid nozzle in a first cross-machine direction of the working surface, a fourth directional liquid nozzle in a second cross-machine direction opposite the first cross-machine direction of the working surface, and a fifth directional liquid nozzle normal to the working surface.
A cleaning head for use in a traversing shower system, said cleaning head comprising:
- a central unit including a central aperture through which vacuum is provided to draw liquid and debris from a working surface;
- at least one forced air nozzle for providing forced air onto the working surface proximate the central aperture;
- and
- a liquid applicator assembly that extends into the central aperture, said liquid applicator assembly including a plurality of directional liquid nozzles for discharging liquid onto the working surface from at least five different directions,
- wherein the plurality of directional liquid nozzles includes a first directional liquid nozzle in a machine direction of the working surface, a second directional liquid nozzle opposite the machine direction of the working surface, a third directional liquid nozzle in a first cross-machine direction of the working surface, a fourth directional liquid nozzle in a second cross-machine direction opposite the first cross-machine direction of the working surface, and a fifth directional liquid nozzle normal to the working surface.
A cleaning head for use in a traversing shower system, said cleaning head comprising:
- a central unit through which forced air and forced liquid are provided to a working surface, and through which a vacuum is provided to draw liquid and debris from the working surface;
- and
- an extension arm extending from the central unit and including an external air knife unit that includes a plurality of air nozzles in a Y-shaped pattern,
- wherein the plurality of air nozzles includes a first plurality of air nozzles that form a stem of the Y-shaped pattern and a second plurality of air nozzles that form a fan of the Y-shaped pattern.
A cleaning head for use in a traversing shower system, said cleaning head comprising:
- a central unit through which forced air and forced liquid are provided to a working surface, and through which a vacuum is provided from the working surface to draw liquid and debris from the working surface;
- and
- an extension arm extending from the central unit and including an external air knife unit that includes a plurality of air nozzles in a pattern that widens in a machine direction of the working surface;
- and
- a liquid applicator assembly that extends into a central aperture of the cleaning head, said liquid applicator assembly including a plurality of directional liquid nozzles for discharging liquid onto the working surface, wherein the plurality of directional liquid nozzles includes at least five directional liquid nozzles, wherein the at least five directional liquid nozzles includes a directional liquid nozzle that is directed normal to the working surface.
