    • 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 rechargeable battery which is connected electrically to the output of a trickle charge transformer unit. 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 energized from the battery for activating 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.
    • 一种洗衣机,包括其中具有可旋转地设置在固定排水桶内的旋转桶的柜,以及由液压地连接到液体喷射器喷嘴的添加液体的多负载容器组成的添加剂液体分配系统。 泵优选地包括耦合到电驱动马达的恒定容积泵,用于从储存器抽吸添加剂液体并以均匀的流速将其从喷嘴排出。 电动机通过控制单元电连接到电连接到涓流充电变压器单元的输出端的可再充电电池。 控制单元包括可调节元件,其设置用于预先选择要注入洗涤负载的添加剂液体的量;以及电动定时器元件,其从电池通电,以激活与所选择的添加剂液体量相对应的时间长度。 喷嘴优选地设置在旋转桶中的开口附近,用于在其中引导从喷嘴排出的添加剂液体。
