Dishwasher additive dispensing apparatus
First Claim
1. Apparatus for dispensing additive into a wash chamber of an automatic washing machine having a programmer-timer control unit comprising:
- container means formed in the inner door wall of said washing machine, said container means disposed so as to be filled when said door is open and to dispense additive when said door is closed;
closure means mounted adjacent said container means, said closure means being rotatably movable in a plane between a first position in which said container means is uncovered and a second position in which said closure means covers said container, said closure means being axially movable in a direction transverse to said plane of rotation between said second position and a third position in which said closure means seals said container means, said closure means having handle means for rotating said closure means in said plane between said first and second positions, and for translating said closure means axially between said second and third positions;
means for biasing said cover toward said first position;
detent means fixedly mounted for rotation with said handle means;
first cam means responsive to said timer control unit, and cam follower means interconnecting said first cam means and said detent means, said follower cooperative with said detent means to hold said closure means in said third position, and to release said closure means at the appropriate time in the washing cycle as determined by said timer control unit.

Abstract
A dishwashing apparatus having a dispenser operable at a preselected time in the dishwashing cycle for dispensing a treating additive such as detergent. The dispenser is arranged so that in response to a timer controlled cam a spring biased shaft to which the dispenser cover is mounted is released and the cover swings away from the dispenser container opening. The shaft is integral with a handle used to close the dispenser cover, and the handle and cover are interconnected by a camming device so that the cover is drawn into sealing engagement with the perimeter of the detergent container by the operator. The camming device further serves to break the seal by moving the cover in an axial direction away from the detergent cup in response to the timer controlled cam. The detergent cup cover utilizes a highly effective rubber seal to compensate various tolerance conditions.
