ABSTRACT:
A dishwashing apparatus having two dispensers operable at preselected times in a dishwashing cycle for dispensing treating additives such as detergent and a rinse aid additive. The dispensers are arranged so that in response to a programmer-timer controlled cam an interlock device to which the detergent dispenser cover is mounted is released and the cover swings away from the dispenser container opening. The interlock includes a shaft integral with a handle used to close the dispenser cover, the other end of the shaft having a unitary detent member secured for rotation with said shaft, said detent including a plurality of latching extensions for operative engagment with the timer controlled cam. Mounted adjacent the detergent dispensing mechanism is the rinse aid dispenser which is also activated by the interlock device. One of the latching members holds the shaft from rotation until the detergent is required, and another of the latching members holds the shaft from rotation until the rinse aid is required. After a complete wash and rinse operation the rinse aid device is held in an inoperative position until the detergent cup cover is closed by the operator.
