Abstract
The disclosed mat washer includes a stand with a slot in the top for admission of a floor mat held by an operator who applies a spray of cleaning fluid to the mat from nozzles inside the unit controlled by a foot pedal. The clean mat can be pulled off the top, or permitted to pass through for deposit on a strainer tray. Various arrangements are provided for support of the mat against a rotating brush as the mat is fed down into the slot for scrubbing by the brush.
Claims10
A mat washer comprising:
- a housing;
- scrubbing roll means and support roll means enclosed in said housing and having substantially horizontal, parallel, and horizontally spaced rotational axes;
- said housing having a slot at the top to admit a mat into a work area in said housing between said roll means;
- motor drive means coupled to said scrubbing roll means for rotational drive thereof;
- cleaning fluid dispenser means enclosed in said housing above said scrubbing roll means for applying cleaning fluid to one face of a mat admitted into said work area;
- said scrubbing roll means having work contacting means thereon moving proximate a support surface of said support roll means for contacting said one face and thereby urging a mat disposed between said scrubbing roll means and said support roll means against said support surface to implement scrubbing of the mat by said work contacting means;
- said dispenser means include a distribution pipe extending parallel to said axes and having a plurality of spray nozzles spaced along it above said scrubbing hole means and directed toward said support roll means for spraying cleaning liquid onto the scrubbing roll facing face of a mat passing vertically between said roll means;
- said housing being constructed to drain continuously from said work area all fluid dispensed and thereby avoid accumulation of fluid around said roll means;
- leg means supporting said housing;
- and
- dispenser control means including a valve in a liquid conduit between a cleaning liquid source and said dispenser means, and a valve control pedal for operating said valve;
- said valve including a flexible walled tube and a pair of cooperating tube-pinching members, one of said members being fixed to said leg means, and the other of said members being fixed to said pedal.
