Abstract
Apparatus for cleaning a surface, comprising brush means including a body (16) which carries bristles (17) engageable with the surface; means for effecting movement of the bristles relative to the surface, to provide an agitating cleaning action thereon; said bristle-carrying body further being provided with steam delivery means (20, 21) for applying steam to said surface in a region thereof engaged by said bristles. The apparatus may be for cleaning a conveyor belt (10), with the brush in the form of a drum (16) rotatable about an axis (18) parallel to the conveyor belt with the steam passing through the drum and emerging through peripheral apertures (21), the brush being disposed within a hood (15) with an extraction system for loosened dirt and water.
Claims16
An apparatus for cleaning a surface comprising:
- a brush having a hollow body with bristles carried on an external surface of a peripheral wall thereof, said brush being disposed within and covered by a hood which is arranged to approach the surface which is to be cleaned;
- a motor for effecting movement of the bristles relative to the surface, to provide an agitating cleaning action thereon;
- and
- a conduit in fluid communication with an interior of said hollow body to provide steam to said interior;
- wherein said hollow body includes a plurality of apertures formed in said peripheral wall for applying steam to said surface in a region thereof engaged by said bristles.
An apparatus for cleaning a surface, comprising:
- a brush having a hollow body with an external peripheral wall and a plurality of bristles extending outwardly from said peripheral wall, said peripheral wall including a plurality of apertures permitting steam to emerge from the interior of the hollow body in the vicinity of said bristles;
- a motor for effecting movement of the brush so that said bristles brush the surface to be cleaned;
- a conduit iii fluid communication with an interior of said hollow body to provide steam to said interior;
- a hood within which said brush is disposed, said hood having boundaries which extend to approach the surface to be cleaned;
- and
- an extractor for matter from the surface to be cleaned, said extractor having at least one intake at at least one of said boundaries of the hood.
An apparatus for cleaning a surface, comprising:
- a brush having a hollow body in the form of a cylinder having a longitudinal axis and an external peripheral wall extending about said longitudinal axis, and a plurality of bristles extending outwardly from said peripheral wall, said peripheral wall including a plurality of apertures permitting steam to emerge from the interior of the hollow body in the vicinity of said bristles,
- a motor for effecting rotation of the brush about said longitudinal axis so that said bristles brush a surface to be cleaned extending substantially parallel to said longitudinal axis;
- a conduit in fluid communication with an interior of said hollow body to provide steam to said interior;
- a hood within which said brush is disposed, said hood having boundaries which extend to approach the surface to be cleaned;
- and
- an extractor for matter from the surface to be cleaned, said extractor having at least one intake at at least one of said boundaries of the hood.
