Touchless toilet assembly

A touchless siphon valve assembly for a toilet assembly having a toilet tank, the touchless siphon valve assembly comprising

• a control assembly;
• and
• a siphon valve assembly,
• wherein
• the control assembly comprises a capacitive sensor, a controller, and a power source, and
• the siphon valve assembly comprises a tubular core, a head coupled to and surrounding an upper end of the tubular core, a spray initiator positioned in the head and extending into the tubular core, and a solenoid valve fluidly coupled to the spray initiator,
• the power source is electrically connected to the capacitive sensor, the controller, and the solenoid valve,
• the capacitive sensor is configured to detect a first gesture, and to indicate detection of the first gesture to the controller to initiate a flush cycle,
• the controller, upon receiving indication of the first gesture from the capacitive sensor, is configured to instruct the solenoid valve to open,
• the siphon valve head comprises an opening having a gate slideably positioned therein, the gate configured to be vertically lifted and lowered between an open and a closed position relative to the opening, respectively,
• the gate open position is configured to provide for a low volume flush cycle, and the gate closed position is configured to provide for a high volume flush cycle,
• the controller is electrically coupled to a lift mechanism comprising a multi-arm linkage configured to lift and lower the gate, and
• the spray initiator, upon opening of the solenoid valve, is configured to spray pressurized water on an entire perimeter of a tubular core inner surface to form a water seal, thereby creating negative pressure in the tubular core and initiating a siphon flow of surrounding water in a toilet tank.
