Auto flush for tank toilet

A system for automatically flushing a toilet of the tank-type, said system comprising:

• at least one infrared radiation beam transmitter, said at least one infrared radiation beam transmitter emitting a radiation beam to a target area in front of the toilet;
• an infrared radiation beam detector, said infrared radiation beam detector being responsive to a reflected radiation beam emitted from the radiation beam transmitter and reflected off of a user in the target area;
• a controller being responsive to an electrical signal from the radiation beam detector indicative of the intensity of the reflected beam;
• a digital read-out being responsive to signals from the controller, said digital read-out providing a visual indication of the operation of the system, wherein the at least one radiation beam transmitter, the radiation beam detector, the controller and the digital read-out are configured on a common circuit board positioned within a housing adapted to be attached to a tank of the toilet;
• a flush motor responsive to a signal from the controller, said flush motor being positioned within a portion of the housing;
• and
• a lift arm actuatable by activation of the flush motor in response to the signal from the controller, said lift arm extending from the housing within the tank and engaging a flush arm within the toilet tank so as to cause the flush arm to flush the toilet, said lift arm engaging below the flush arm so as to allow the flush arm to flush the toilet in response to manual activation of a flush handle on the outside of the tank;
• and,
• a lift arm adjustment switch configured on the circuit board, said lift arm adjustment switch operable to set the travel of the lift arm so as to calibrate to the flush arm.

• an automatic toilet seat device, said automatic toilet seat device automatically raising or lowering a toilet seat of the toilet in response to a flush from the system;
• and,
• a float switch adapted to be positioned within the toilet tank of the toilet for providing a flush signal in response to a flush of the toilet, said controller being responsive to said flush signal from the float switch for actuating said toilet seat device.
