A device for use in the regeneration of ion exchanger in a dishwater comprises a reservoir 1, which is supplied with water via inlet nozzle 6, channel 9, and orifice 10, an air-break 4 being provided in the supply line. Liquid may be discharged from the reservoir via orifice 11, channel 12, and outlet nozzle 7 to an ion exchange unit. Nozzle 8 may be connected to a salt container. Walls 14, 15 are provided in the reservoir at least partly defining outlet channels 16, 17, 18 leading to rotary valve 19 located adjacent grille 2 communicating with vent 3. In use, water is normally supplied via the reservoir to the ion exchange unit. To regenerate the ion exchanger, water in channel 18 is passed into the salt container, the resulting saline solution being supplied to the ion exchange unit. If more water is required for this purpose, the rotary valve is turned to discharge water first via channel 17, and then channel 16 into channel 13 for delivery to the salt container. <IMAGE> |
