Abstract
A method and apparatus for washing the surface of an object in which a rotating brush is provided. The bristles of the brush are supplied with a washing liquid through a hollow shaft for a limited angular rotation so that the washing liquid effectively is transmitted to the ends of the bristles substantially only during the time they make contact with the surface.
Claims17
A method for washing a surface with a washing device having cleaning bristles which rotate about a hollow shaft comprising the steps of moving the washing device in a first direction relative to the surface to be washed, contacting said surface with the bristles, rotating the washing device relative to said surface in a direction counter to said first direction at the area of contact with said surface, providing a washing liquid, and supplying the washing liquid from said hollow shaft to the rotating washing device only during a limited angle of rotation of each revolution of the device said angle ending just prior to the contact area between the bristles and the surface so that substantially all the washing liquid ejected from the device moves toward said surface.
Apparatus for washing a surface comprising:
- washing means having rotatable cleaning bristles to contact the surface;
- means for rotating said washing means comprising a hollow shaft;
- means for supplying a washing liquid to said washing means through said hollow shaft during a limited angle of each revolution of its rotation such that said washing liquid is ejected toward the surface only on one side of and throughout the contact area between the bristles and the surface;
- an elongated flushing spray line;
- means for mounting said flushing spray line generally parallel to said hollow shaft;
- and
- means for supplying flushing liquid through the hollow shaft to the flushing spray line to impinge on the surface on the other side of said contact area.
Apparatus for washing a surface comprising:
- washing means having rotatable cleaning bristles to contact the surface, said washing means comprising at least one generally cylindrical unit;
- means for rotating said washing means comprising a hollow shaft;
- means for mounting said at least one unit generally parallel to the axis of said hollow shaft;
- and
- means for supplying a washing liquid to said washing means through said hollow shaft during a limited angle of each revolution of its rotation, said angle ending just prior to the contact area between the bristles and the surface such that substantially all the liquid ejected from the washing means impinges upon the surface only on one side of and throughout said contact area.
An apparatus for washing a surface comprising:
- washing means having cleaning bristles which rotate about a hollow shaft to contact the surface, means for moving the washing means in a first direction relative to the surface to be washed, means for rotating the washing means in a direction counter to said first direction at the area of contact between the bristles and the surface, means for providing a washing liquid, and means for supplying the washing liquid from said hollow shaft to the rotating washing means only during a limited angle of rotation of each revolution of the washing means, said angle ending just prior to the contact area between the bristles and the surface such that said liquid impinges upon the surface only ahead of and throughout said contact area.
Apparatus for washing a surface comprising:
- a washing device having a rotatable brush to contact the surface;
- means for moving the brush in a first direction relative to the surface to be washed;
- means for rotating the device relative to said surface in a direction counter to said first direction at the area of contact between the brush and the surface;
- means for introducing separate washing and flushing fluids substantially concentrically within the rotary brush, said washing fluid being supplied to the rotating device only during a limited angle of rotation of each revolution of the device and on one side of and throughout the contact area between the brush and the surface, said flushing fluid being substantially continuously sprayed on the surface on the other side of the contact area between the brush and the surface.
