Abstract
A washing appliance such as a dishwasher or laundry washing machine comprises an ion-exchange water softening section and a brine generator to supply brine to the water softening section to regenerate ion-exchange resins therein, and a valve (such as a float valve) in a water supply conduit to the brine generator. The valve permits water to flow into the brine generator but blocks back-flow of liquid from the brine generator to the water supply conduit.
Claims20
A washing appliance comprising:
- a water softener containing ion-exchange resin,
- a brine generator to supply brine to the water softener for regenerating the ion-exchange resin therein, the brine generator having a brine container with a filling orifice to allow solid salt to he added to the brine container,
- a water supply path for providing water, via an entrance port, to the brine container, and
- a valve that opens the entrance port when the liquid in the brine container is at a relatively low level and closes the entrance port when liquid in the brine container is at a relatively high level, the valve preventing backflow of liquid from the brine container to or through the water supply path when the liquid is above the level of the entrance port so that brine displaced by solid salt added to the brine container is able to flow out of the brine container via the filling orifice in preference to the water supply path.
