Abstract
Fluid supply assemblies for fluid systems are provided, including faucet assemblies (e.g., electrically or mechanically actuated faucet assemblies) having an integrated anti-scald device and having an integrated temperature mixing valve. An exemplary faucet assembly includes an integrated temperature mixing valve, and/or an integrated anti-scald device configured to stop the inlet flow of hot water in the event the mixed outlet water temperature exceeds a user-selected set point. The faucet assemblies can prevent scalding as defined by ASSE 1070.
Claims18
A fluid supply assembly comprising:
- a mixing valve housed in a mixing cavity;
- and
- an anti-scald device housed in an anti-scald cavity, the anti-scald device comprising:
- a thermal actuator and a plunger, wherein the thermal actuator is configured to move the plunger to close a hot fluid inlet when a temperature of a mixed fluid flow, formed from hot fluid and cold fluid mixed in the mixing cavity, reaches a set-point temperature;
- and
- an adjustable cap member mounted to a first end of the anti-scald cavity and a stopper mounted to the first end of the anti-scald cavity;
- wherein the stopper is configured for stopping a motion of the cap member away from a second end of the anti-scald cavity, and the cap member is adjustable to move from the stopper toward the second end of the anti-scald cavity;
- wherein after the cap member is moved toward the second end of the anti-scald cavity, a set point temperature of a sensing region decreases;
- and
- wherein after the cap member is moved away from the second end of the anti-scald cavity, the set-point temperature of the sensing region increases.
