Abstract
An anti-scald device, fluid supply system including an anti-scald device and methods are provided. The anti-scald device can be configured to provide scald protection as well as configured to allow hot water disinfection.
Claims26
An anti-scald device for a fluid supply system comprising:
- a housing having a first cavity, the first cavity including a hot fluid inlet, a cold fluid inlet and a first cavity outlet;
- an anti-scald assembly positioned, at least in part, within the first cavity, the anti-scald assembly having a thermostatic element coupled to a shuttle, the anti-scald assembly transitionable between a first configuration and a second configuration;
- in the first configuration, the thermostatic element moves the shuttle relative to the hot fluid inlet between a hot fluid low flow position and a hot fluid high flow position in response to a temperature of fluid within the first cavity to maintain the temperature of the fluid exiting the first cavity through the first cavity outlet at or below a set point temperature;
- and
- in the second configuration, the thermostatic element is prevented from moving the shuttle relative to the hot fluid inlet to maintain the temperature of the fluid exiting the first cavity below the set point temperature.

An anti-scald device for a fluid supply system comprising:
- a housing having:
- a first cavity including a hot fluid inlet, a cold fluid inlet and a first cavity outlet through which fluid exits the first cavity;
- a second cavity including a tempered fluid inlet, a cold fluid inlet and a second cavity outlet through which fluid exits the second cavity, the tempered fluid inlet being in fluid communication with the first cavity outlet such that fluid exiting the first cavity through the first cavity outlet flows into the second cavity through the tempered fluid inlet;
- an anti-scald assembly positioned, at least in part, within the first cavity, the anti-scald assembly having a thermostatic element coupled to a shuttle, the thermostatic element moves the shuttle relative to the hot fluid inlet between a hot fluid low flow position and a hot fluid high flow position in response to a temperature of fluid within the first cavity to maintain the temperature of the fluid exiting the first cavity through the first cavity outlet at or below a set point temperature;
- a valve member adjustably positioned within the second cavity for adjusting a flow of a least one of the flow of fluid into the second cavity through the tempered fluid inlet and through the cold fluid inlet to control an outlet temperature of the fluid exiting the anti-scald device.
