Touchless flushing systems and methods

A toilet, comprising:

• a touchless sensor;
• a motor assembly;
• a processing circuit configured to receive a signal from the touchless sensor and to activate the motor assembly based on the signal;
• a wheel assembly coupled to the motor assembly and configured to rotate when the motor assembly is activated, the wheel assembly comprising a magnet and a link;
• a switch configured to detect presence of the magnet and to transmit a deactivation signal to the processing circuit in response to detecting presence of the magnet;
• a closed reservoir configured to contain flush water and a flush valve and defined by a plurality of walls;
• and
• a housing within which the touchless sensor, the motor assembly, the switch, and the processing circuit are contained, the housing coupled to at least one of the plurality of walls of the closed reservoir such that the touchless sensor is located within the closed reservoir;
• wherein the touchless sensor is configured to transmit the signal to the processing circuit in response to detecting an object external to the closed reservoir;
• wherein activation of the motor assembly facilitates flushing of the toilet;
• and
• wherein the processing circuit is configured to deactivate the motor assembly based on the deactivation signal;
• and
• wherein the link is configured to be coupled to the flush valve.

A method for flushing a toilet comprising:

• projecting, by a touchless sensor of a touchless actuation system, an electromagnetic field through a closed reservoir of the toilet, thereby defining a detection region external to the closed reservoir, the closed reservoir comprising a bottom and at least one wall extending upward therefrom;
• transmitting, by the touchless sensor, a signal to a processing circuit of the touchless actuation system when an object enters the detection region;
• activating, by the processing circuit, actuation of a motor assembly of the touchless actuation system in response to receiving the signal;
• and
• rotating, by the motor assembly, a wheel assembly at least one full rotation in response to being actuated;
• wherein rotation of the wheel assembly facilitates flushing of the toilet;
• wherein the touchless sensor, the motor assembly, and the processing circuit are contained in a housing that is coupled to the at least one wall of the closed reservoir such that the touchless sensor is located within the closed reservoir;
• and
• wherein the wheel assembly is external to the housing.
