초록 ▼

A floor cleaning machine is provided that includes a chassis that supports at least one cleaning element and a fluid collection assembly for pooling and retaining cleaning fluids proximate to the at least one cleaning element. A floor cleaning machine is provided that includes a cleaning fluid dispersion apparatus and a cleaning fluid collection assembly for efficiently dispensing fluid on a surface for cleaning the surface, and collecting the dispensed fluid to maximize the cleaning capacity of the fluid and extend the time of a cleaning cycle.

1. A floor cleaning machine, comprising: a chassis that is supported by a plurality of wheels;at least one vessel for holding unused cleaning fluids and at least one vessel for holding spent cleaning fluids;at least one dispensing apparatus for dispensing unused cleaning fluid;at least one vacuum apparatus for retrieving spent cleaning fluids; anda floor cleaning apparatus comprising: a substantially circular brush rotatable about a substantially vertical axis wherein the machine is devoid of any other brush;a first squeegee spaced about 0.2 to 1.0 inches from said substantially circular brush and having a generally arcuate shape which substantially conforms to an outer contour of said brush along approximately 180° of the circumference of said brush, said first squeegee comprising a plurality of apertures on a bottom edge of said first squeegee;a second squeegee having a generally arcuate shape and positioned on the opposite side of said first squeegee as said brush;wherein said first squeegee is positioned substantially flush to a floor surface to permit a pooling area of cleaning fluid thereon, said cleaning fluid at least partially overlapping the area of the floor surface in contact with said brush, so that at least a portion of said brush may continually pass through said pooling area, wherein said plurality of apertures in said first squeegee are positioned a distance away from each other to permit fluid to exit said pooling area by passing through said plurality of apertures;wherein at least two apertures are in fluid communication with said at least one vacuum apparatus and are spaced a distance apart from a mid-point of the first squeegee such that said mid-point of said first squeegee is devoid of apertures such that said pooling area of cleaning fluid is provided at least partially between said at least two apertures, and said pooling area maintains said brush in a substantially lubricated state wherein a fluid flow rate through said first squeegee is less than approximately 0.50 gallons per minute. 2. The floor cleaning machine according to claim 1 wherein said plurality of apertures are comprised of two apertures spaced about 12.58 inches linearly from each other, and each of said two apertures is equidistant from a midpoint of said first squeegee. 3. The floor cleaning machine according to claim 1 wherein said first and second squeegees are rotatable about said brush as the floor cleaning machine changes direction and maintains said pooling area against said first squeegee when the floor cleaning machine changes direction. 4. The floor cleaning machine according to claim 1 wherein said second squeegee is spaced a greater distance from said brush than said first squeegee and is devoid of apertures. 5. The floor cleaning machine according to claim 1 wherein said first squeegee is spaced about 0.25 inches from said outer contour of said brush. 6. The floor cleaning machine according to claim 1 wherein each of said plurality of apertures comprise a height extending from said bottom edge of said first squeegee by about 7/16 inches and are about ¼ inches wide. 7. A floor cleaning machine, comprising: a chassis connected to a plurality of wheels that supports at least one vessel for holding unused cleaning fluids and at least one vessel for holding spent cleaning fluids;a substantially circular brush rotatable about a vertical axis, and wherein the machine is devoid of any other brush;a leading squeegee proximate to said brush and having a generally arcuate shape which substantially conforms to an outer contour of said brush along approximately 180° of the circumference of said brush, said leading squeegee having two apertures, each positioned a distance away from a radial midpoint of said leading squeegee to permit fluid to pass therethrough and said leading squeegee spaced about 0.2 to 1.0 inches from said outer contour of said brush; anda trailing squeegee positioned adjacent said leading squeegee and on the opposite side of said leading squeegee as said brush;wherein the leading squeegee and the trailing squeegee are allowed to pivot about a central axis and thereby prevent pooled cleaning fluid from being carried away from said squeegees;wherein, when said leading squeegee is positioned substantially flush to a floor surface and cleaning fluid is dispensed by the floor cleaning machine, an area of cleaning fluid becomes retained against said leading squeegee between said two apertures to effect a pooling of cleaning fluid on a floor surface at least partially overlapping an area in contact with the brush so that the brush may continually pass through the pooling area and clean the floor surface, said retained cleaning fluid at least partially overlapping said brush so that at least a portion of said brush passes through said retained cleaning fluid during rotation of said brush; andwherein a first aperture and a second aperture are spaced a linear distance apart from a mid-point of the leading squeegee by at least about 6 inches from the mid-point such that the mid-point is devoid of apertures and such that a continuous central portion of the leading squeegee is provided, wherein said pooling area of cleaning fluid is provided at least partially between the apertures and said pooling area maintains said brush in a substantially lubricated state; andwherein a fluid flow rate through said leading squeegee is less than approximately 0.50 gallons per minute. 8. The floor cleaning machine according to claim 7 wherein said two apertures are spaced linearly about 12.58 inches from each other, each of said two apertures being equidistant from said radial midpoint of said leading squeegee. 9. The floor cleaning machine according to claim 8 wherein said two apertures are in fluid communication with at least one vacuum apparatus for removing cleaning fluid passing through said two apertures and for confining said retained cleaning fluid pooled against said leading squeegee between said two apertures. 10. The floor cleaning machine according to claim 9 wherein said trailing squeegee is spaced a greater distance from said brush than said leading squeegee and is substantially devoid of apertures to collect spent cleaning fluid to be retrieved by said vacuum apparatus. 11. The floor cleaning machine according to claim 10 wherein said at least one vacuum apparatus provides vacuum pressure via a hose or tube. 12. The floor cleaning machine according to claim 7 wherein said leading squeegee is spaced about 0.25 inches from said outer contour of said brush. 13. The floor cleaning machine according to claim 7 wherein said two apertures comprise a height extending from a bottom edge of said leading squeegee by about 7/16 inches and are about ¼ inches wide. 14. The floor cleaning machine according to claim 7 wherein said leading and trailing squeegees are rotatable about said brush as the floor cleaning machine changes direction and maintains the cleaning fluid against said leading squeegee when the floor cleaning machine changes direction.
