LIQUID LEVEL INDICATING DEVICE FOR MOVABLY MOUNTED DISPENSER TANKS

A liquid level indicator device for providing a visual indication of the level of liquid within a movably mounted tank, disclosed as a dishwasher door mounted rinse-aid liquid dispenser tank, in which the dispenser tank is alternately positioned in either the vertical or horizontal position by the opening and closing of the door. The liquid level indicator includes a tank wall mounted indicator housing defining a viewing chamber into which is passed a small quantity of liquid when the tank is in the vertical or door closed position if the level is above a predetermined level and a portion of which liquid is retained within the viewing chamber as the tank moves to the door open position to enable viewing of the liquid through a sight window provided. The capture and retention of liquid within the viewing chamber is carried out by means of a catch cup mounted beneath the sight window, with clearance spaces allowing entrance of liquid when the dispenser tank is in the vertical position, but the orientation of the catch cup preventing escape of the liquid as the dispenser tank is moved to the horizontal position and the liquid retreats from the tank wall to which the indicator housing is mounted. The vividness of the visual impression created by the presence of the liquid in the viewing chamber is enhanced by the use of high contrast treatment of the bottom surface of the catch cup within which the liquid is retained.
