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.

Claims

1. A clothes washing machine comprising:

a cabinet having a front defining wall provided with a vertically elongated window;

a drain tub disposed in said cabinet and adapted for holding wash water;

a spin tub rotatably disposed within said drain tub, for processing a wash load in said cabinet; and

an additive liquid dispensing system disposed in said cabinet for dispensing additive liquid to said wash water, said dispensing system comprising a reservoir including housing means having a hollow interior portion for holding a multi-load quantity of the additive liquid and supplying respective smaller quantities of the additive liquid to successive wash loads in said drain tub, said dispensing system further comprising additive liquid viewing means comprising a transparent portion of said reservoir aligned with said window for determining the level reached by the quantity of additive liquid in said housing means.

2. A clothes washing machine as set forth in claim 1 wherein said transparent portion of said reservoir comprises an elongated transparent portion of said housing means extended coextensively with said window.

3. A clothes washing machine as set forth in claim 2 wherein said liquid level viewing means includes a light radiating means disposed adjacent said transparent portion of said housing means for illuminating said additive liquid therein.

4. A clothes washing machine as set forth in claim 3 wherein said elongated transparent portion of said housing includes wall means coated with light reflective material for enhancing illumination of said additive liquid in said transparent portion.

5. A clothes washing machine as set forth in claim 3 wherein said liquid level viewing means includes a liquid level measuring means provided in said transparent portion of said housing means for indicating the level of liquid in said housing means.

6. A clothes washing machine as set forth in claim 2 wherein said transparent portion of said housing means comprises a hollow tubular member extended coextensively with said interior portion of said housing means and communicating hydraulically therewith.
