Abstract
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 reservoir comprises a liquid-tight housing which is vertically elongated and has a triangular cross-sectional shape for fitting into an elongated corner portion of the cabinet adjacent a front defining wall thereof. A side of the housing adjacent the front defining wall has a vertically elongated transparent portion disposed coextensively in alignment with a vertically elongated window in the front defining wall of the cabinet. The transparent portion of the housing may comprise a vertically extending tubular member disposed in communication with additive liquid in the housing such that the level of liquid in the tubular member is an indication of the level of liquid in the housing. A light radiating means may be disposed adjacent the tubular member which may have wall portions coated with light reflective material for illuminating the liquid in the tubular member. Also, a wall portion of the tubular member may be provided with graduations for measuring the amount of liquid in the housing.
