Mechanically actuated additive dispenser for dishwasher

Abstract

Dishwasher dispensing structure consisting of a reservoir for storing a supply of additive and having an outlet, a cover mounted for movement relative to the reservoir between (a) a closed position and (b) an open position, a trigger mounted movably between a cover block position and a cover release position for selectively maintaining the cover in its closed position and releasing the cover to its open position, a cover release member movable by the timer mechanism through a first prescribed path in response to operation of the timer mechanism in a first direction through a portion of the path during one portion of the operating cycle and to retrace the path portion in a second, opposite direction during another portion of the cycle, trigger moving structure movable in a third path as the cover release member moves through the one portion of the cycle and in a fourth path that substantially retraces the third path as the cover release member moves in the another portion of the cycle, and cooperating structure on the trigger moving structure and trigger for (a) moving the trigger from its cover block position to its cover release position as the trigger moving structure moves in the fourth path and (b) allowing the trigger moving structure to move relative to the trigger in its blocked position without moving the trigger from its blocked position as the trigger moving structure moves in the third path.
