ADDITIVE DISPENSING SYSTEM FOR WASHING MACHINE

摘要

A clothes washing machine including a cabinet having therein a spin tub rotatably disposed within a stationary drain tub, and an additive liquid dispensing system comprised of a multi-load reservoir of additive liquid connected hydraulically through a pump to a liquid ejector nozzle. The pump preferably comprises a constant displacement pump coupled to an electrical drive motor for drawing additive liquid from the reservoir and expelling it from the nozzle at a uniform rate of flow. The motor is connected electrically through a control unit to a source of alternating current, such as a conventional source used for operating the washing machine, for example. The control unit includes an adjustable element disposed for preselecting the quantity of additive liquid to be injected into the wash load, and an electrical timer element for energizing the motor a length of time corresponding to the quantity of additive liquid selected. The nozzle preferably is disposed adjacent an opening in the spin tub for directing therein the additive liquid expelled from the nozzle.
