Steam cleaning apparatus
View Patent ↗A surface cleaning apparatus, and in particular a steam mop, comprises a steam delivery system for generating and distributing steam onto a surface to be cleaned. The steam mop further comprises a handle assembly mounted to a foot assembly that has a manifold configured to supply steam from a steam generator to the surface to be cleaned.
1. A surface cleaning apparatus comprising:
a foot assembly for movement along a surface to be cleaned;
a handle assembly mounted to the foot assembly;
a steam generator;
an opening in the foot assembly in fluid communication with the steam generator;
a forward steam distributor positioned at a forward portion of the foot assembly and configured to supply steam to the surface to be cleaned;
a rearward steam distributor positioned at a rearward portion of the foot assembly and configured to supply steam to the surface to be cleaned; and
a manifold fluidly connecting the opening to the forward and rearward steam distributors;
wherein the manifold comprises an X shaped conduit comprising two forward channels which radiate forwardly from the opening to the forward steam distributor and two rearward channels which radiate rearwardly from the opening to the rearward steam distributor.
2. The surface cleaning apparatus according to claim 1 wherein the handle assembly is swivelably mounted to the foot assembly.
3. The surface cleaning apparatus according to claim 1 and further comprising a fluid supply tank fluidly connected to the steam generator for supplying cleaning fluid to the steam generator.
4. The surface cleaning apparatus according to claim 1 wherein at least one of the forward and rearward steam distributors extend across at least a substantial lateral portion of the foot assembly.
5. The surface cleaning apparatus according to claim 4 wherein the forward and rearward steam distributors comprise one of a narrow slit-opening, a plurality of small apertures or slits, and a cat-eye opening.
6. A surface cleaning apparatus comprising:
a foot assembly for movement along a surface to be cleaned;
a handle assembly mounted to the foot assembly;
a steam generator;
an opening in the foot assembly in fluid communication with the steam generator;
a forward steam distributor positioned at a forward portion of the foot assembly and configured to supply steam to the surface to be cleaned;
a rearward steam distributor positioned at a rearward portion of the foot assembly and configured to supply steam to the surface to be cleaned;
a manifold fluidly connecting the opening to the forward and rearward steam distributors; and
a shuttle plate mounted to the foot assembly for reciprocal movement between a forward position and a rearward position;
wherein the shuttle plate is configured to close off the forward steam distributor in the forward position and to close off the rearward steam distributor in the rearward position; and
wherein the rearward steam distributor is open when the shuttle plate is in the forward position and the forward steam distributor is open when the shuttle plate is in the rearward position.
7. The surface cleaning apparatus according to claim 1 and further comprising a cleaning implement removably mounted to the foot assembly.
8. The surface cleaning apparatus according to claim 7 wherein the cleaning implement is one of a mop cloth, scrubbing pad, scrub brush, and cleaning sheet.
9. The surface cleaning apparatus according to claim 8 wherein the foot assembly comprises a one of elastic straps, adhesive strips, resilient cloth engagement and retention members having radiating slits, and a hook or loop fasteners for removably attaching the cleaning implement to the foot assembly.
10. The surface cleaning apparatus according to claim 1 and further comprising a vacuum source mounted to at least one of the foot assembly and the handle assembly wherein the foot assembly includes at least one suction nozzle connected to the vacuum source and adapted to contact the surface to be cleaned and to draw moisture and debris from the surface.
11. a surface cleaning apparatus comprising:
a foot assembly for movement along a surface to be cleaned;
a handle assembly mounted to the foot assembly;
a steam generator;
an opening in the foot assembly in fluid communication with the steam generator;
a forward steam distributor positioned at a forward portion of the foot assembly and configured to supply steam to the surface to be cleaned;
a rearward steam distributor positioned at a rearward portion of the foot assembly and configured to supply steam to the surface to be cleaned;
a manifold fluidly connecting the opening to the forward and rearward steam distributors; and
a vacuum source mounted to at least one of the foot assembly and the handle assembly, wherein the foot assembly includes at least one suction nozzle connected to the vacuum source and adapted to contact the surface to be cleaned and to draw moisture and debris from the surface;
wherein the at least one suction nozzle includes a forward suction nozzle positioned at a forward portion of the foot assembly and a rearward suction nozzle positioned at a rearward portion of the foot assembly.
12. The surface cleaning apparatus according to claim 11 wherein the forward suction nozzle is adjacent the forward steam distributor and the rearward suction nozzle is adjacent the rearward steam distributor.
13. The surface cleaning apparatus according to claim 1 and further comprising a spray nozzle fluidly coupled with the steam generator and aligned with the opening.
14. The surface cleaning apparatus according to claim 1 wherein each channel comprises a U-shaped member having a bottom wall and opposed side walls extending upwardly from the bottom wall.
15. The surface cleaning apparatus according to claim 14 wherein the X-shaped conduit is mounted on the underside of the foot assembly to close the U-shaped members.
