Patent ID: 7255327

Claim:
A hands free water system, comprising: a sealed chamber body adapted for containing a mixing ball valve and having chamber ports further serving as internal passages to channels adapted to said sealed chamber body for connection to water line tubing, said sealed chamber body and associated output channels featuring standard plumbing connections that enable interface to pre-existing plumbing fixtures; a mixing ball valve substantially retained within said sealed chamber body and having delivery and exit ports through which water can enter and exit the mixing ball valve, wherein said mixing is adapted for rotation in relation to the fixed chamber body for selective alignment with said chamber ports and wherein said mixing ball further comprises a keyed slot limiting rotation of said mixing ball valve by a corresponding fixed orientation pin included within an inner cavity of the sealed chamber body; a foot controllable actuator in operational connection with said mixing ball valve, wherein a faucet system user can cause rotation of said mixing ball valve with said foot controllable actuator to control water flow rate and temperature; and a control state module adapted to guide said foot controllable actuator into at least one operation state at a time, said operation state including: “BYPASS”, “OFF”, “ON”, “HOT”, or “COLD”, wherein the user can engage the “hands free” device by foot-switching the system to or from the “BYPASS” state to or from any of the “OFF”, “ON”, “HOT”, or “COLD” states using said foot controllable actuator; wherein the “BYPASS” state causes placement of the mixing ball valve's orientation in the maximum flow rate of hot water; and wherein output from the sealed chamber body and mixing ball valve is in an in-line supply or series arrangement with corresponding conventional faucet “hot water” control valving, wherein assertion of the “hands free” device in the “BYPASS” state provides a single source of supply of hot water to the conventional faucet.
