  • Patent number: 4835993
    Abstract: A commercial/industrial washing machine is provided with a body section which is pivotable between a loading and washing position in which the body section is horizontal, and an unloading position in which the body is forwardly inclined at an angle of approximately 7.5.degree.. The body section carries a washing drum which is rearwardly and downwardly inclined at an angle of approximately 2.5.degree. relative to the body section and is provided with internal breaker ribs inclined at an angle of approximately 15.degree. relative to the drum axis. A loading chute is pivotally connected to the upper end of the body section and is movable between a raised position in which the chute is spaced apart from the drum opening, and a lowered position in which the chute outlet communicates with the interior of the drum, the chute being provided with a counterweight system to counterbalance the weight of the chute.

  • Patent number: 4777682
    Abstract: An industrial laundry washer/extractor unit is provided with an integral water and heat reclaim system which includes a pair of water reclaim tanks supported in an elevated position on the unit's body section above the washing drum. A single pipe water transfer system is connected between the elevated tanks and the drum and has a pump operatively installed therein at or somewhat below the water operating level of the drum. The transfer system is controlled by a microprocessor to transfer used rinse water at different temperatures from the drum to the tanks and then re-transfer tank water to the drum for re-use as wash water in subsequent wash cycles of the unit. The temperatures of the reclaimed rinse water in the tanks closely match the wash temperatures in subsequent wash cycles so that a significant water heating cost savings is achieved together with reduced water and cleaning agent usage.
