Dishwasher front panel

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.

Mechanically actuated additive dispenser for dishwasher

A dishwashing apparatus having a wash chamber, a timer, an additive reservoir and a dispenser for selectively closing and opening the reservoir. The improvement is a follower for moving in a prescribed path as the timer mechanism is cycled an actuating member consisting of first and second relatively movable parts connected to the follower and dispenser and causing the dispenser to move from its closed to its open state as the timer operates during one portion of a cycle and movement of the actuating member in a first path portion in a first direction and for causing the dispenser to move in a second path portion that substantially retraces the first path portion in a direction opposite to the first direction during another portion of an operating cycle, structure for biasably holding the actuating member parts together in operative position and for permitting one actuating member part to be moved relative to the other against a force imparted by the holding structure to a separated position as the one actuating member part is moved in one of the first and second path portions, structure for blocking movement of the one actuating member part in the one path portion, and cooperating structure on the one actuating member part and follower to permit adjustable fixing of the relative positions of the follower and one actuating member part as the one actuating member part is blocked moving in the second path portion and the follower is moved during a cycle.

Two part actuating member for an additive dispenser on a dishwasher

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.
