Problems solved by technology

If such a device is left switched on when placed upon a bench for example, it can spin haplessly and run away across the bench.
Also, the cleaning action provided by such known devices is limited by the unidirectional rotation of the bristles or other cleaning surface-interactive element.

Embodiment Construction

[0036] In FIG. 1 of the accompanying drawings there is depicted schematically an electric body scrubber for use in the shower or bath comprising a housing provided by a cover 7 and a base 3. The cover 7 houses a plate 8 on which there is mounted an electric switch 6 activatable upon depression of a sealed pushing pad 71 on the cover.

[0037] There is an electric motor 501 attached to a frame 9 that is in turn secured to a base 3. A rechargeable battery pack 4 is fitted upon the base 3 and provides power to the electric motor 501 when the switch 6 is depressed. The housing is sealed against the ingress of water from the outside.

[0038] A worm gear 503 is secured to the output shaft of the electric motor 501. The frame 9 supports the worm gear 503 as well as an intermediate gear 502 with which the worm gear 503 meshes The depending shaft from the intermediate gear 502 passes through the base 3. At the bottom side of the base, a pinion 504 is secured to the intermediate gear shaft so as...

Abstract

An electric scrubber includes a housing, an electric motor mounted within a housing, a pair of scrubbing blocks mounted to the housing for rotation about a common axis, and a torque transmission transmitting torque from the electric motor to the scrubbing blocks in such manner that the scrubbing blocks rotate simultaneously in mutually opposite directions about the common axis.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to electric motor-driven scrubbers. More particularly, although not exclusively, the invention relates to motor-driven scrubbers having a pair of scrubbing blocks that are driven to counter-rotate about a common axis. Such scrubbing blocks might support a plurality of tufts, polishing pads, scouring pads, sandpaper, cleaning sponges or other surfaces for cleaning, scrubbing, polishing or the like. [0002] It is known to provide handheld motor-driven rotary brushing devices provided with a single flat tuft block from which parallel bristles extend. The tuft block in such devices rotates in one direction only. If such a device is left switched on when placed upon a bench for example, it can spin haplessly and run away across the bench. Also, the cleaning action provided by such known devices is limited by the unidirectional rotation of the bristles or other cleaning surface-interactive element. OBJECT OF THE INVENTION [00...
