Abstract
A dishwashing apparatus having a dispenser operable at a preselected time in the dishwashing cycle for dispensing a treating liquid such as a rinse additive. The dispenser is arranged so as to measure in a measuring cup a preselected quantity of additives as an incident of moving the dishwasher door between opened and closed positions and to dispense the preselected quantity at the proper time in the wash cycle. The measuring cup for the additive is pivotally mounted within the dispenser and is pivoted from a position submerged in the liquid additive when the dishwasher door is opened in the horizontal plane, and above the liquid additive level when the dishwasher door is closed in the vertical plane, to a position so as to discharge the liquid by gravity into a discharge conduit. The discharge conduit additive receiving opening is located above the level of the liquid additive at all door positions and conveys the liquid additive by gravity into the washing chamber. The pivoting of the measuring cup is effected at the desired preselected time in the dishwashing cycle.
