ABSTRACT:
A dispensing apparatus for automatically dispensing detergent into a laundry machine. The electrical current drawn by the laundry machine is monitored by a detecting device to detect when the electrical current exceeds a predetermined threshold current. When the electrical current exceeds the threshold current, the detecting device transmits a signal indicating that detergent should be conveyed from the detergent supply to the washtub of the laundry machine by a conveying device. The signal is delayed for a predetermined period of time by a delay timer. After the delay, the conveying device is controlled to convey the detergent. If the washing process is interrupted for less than a predetermined period of time, a dwell timer prevents multiple conveyance of detergent into the washtub.
