ABSTRACT:
Dishwasher dispensing structure consisting of a reservoir for storing a supply of additive and having an outlet opening to the wash chamber, a cover movably mounted relative to the reservoir between a) a closed position wherein the cover prevents escape of additive from the reservoir outlet into the wash chamber and b) an open position permitting the reservoir outlet to be in communication with the wash chamber, a trigger mounted movably to the dishwasher between a cover block position and a cover release position, with structure on the trigger for maintaining the cover in the closed position with the trigger in its blocked position and releasing the cover to its open position with the trigger in its cover release position, a cover release member, structure driven by the timer mechanism for moving the cover release member through a first prescribed path in response to operation of the timer mechanism as the dishwasing apparatus is cycled and moving the cover release member in a first direction through a portion of the path during one portion of the operating cycle and moving the cover release member to retrace the path portion in a second direction opposite to the first direction during another portion of the cycle, trigger moving structure on the cover release member mounted for movement in a third path as the cover release member moves through the one portion of the operating cycle and in a fourth path that substantially retraces the third path as the cover release member moves in the another portion of the operating cycle.
