ABSTRACT:
An automatic flushing system for a tank-type toilet. The automatic flushing system includes one or more infrared transmitters that transmit an infrared signal to a sensing area directly in front of a toilet bowl of the toilet. The presence of a user in the sensing area is detected by the system from a reflection of the transmitted infrared beam off of the user. Detection of the user in the sensing area for a predetermined minimal period of time causes an automatic courtesy flush. Once the user has left the sensing area, the automatic flushing system will provide a main flush. The automatic flushing system includes a lift arm operated by a flush motor positioned within the toilet tank. Activation of the motor causes the lift arm to push against a flush arm in the toilet tank to flush the toilet. The lift arm is positioned beneath the flush arm to allow for manual flushing.
