  • Patent number: 12084361
    Abstract: An apparatus for controlling a water softener according to an exemplary embodiment of the present invention includes: a concentration detector detecting a concentration of total dissolved solids in water introduced into a channel; a voltage controller controlling a voltage applied to an electrode so that the detected concentration of the total dissolved solids reaches a target concentration; a flow rate detector detecting a flow rate of the water introduced into the channel; and a water softening time controller controlling, based on the detected flow rate, a water softening time for the water so that the detected concentration of the total dissolved solids reaches the target concentration.

  • Patent number: 11852601
    Abstract: According to the present invention, an electrode terminal assembly for a liquid quality meter apparatus for measuring liquid quality on the basis of the electrical resistance of a liquid to be measured comprises: a pair of electrode terminals comprising a body, which contacts the liquid being measured when liquid quality is measured and has an overall rod shape, and a protruding step formed at a predetermined portion between the opposite ends of the body; and a fixing body comprising a pair of electrode through-holes through which the pair of electrode terminals pass. In the electrode terminal assembly having the above-described structure, each of the pair of electrode terminals is arranged such that, when the electrode terminals are inserted into the electrode through-holes of the fixing body by a predetermined length, the protruding step is caught by the fixing body so that the electrode terminals are no longer inserted.

  • Publication number: 20230128055
    Abstract: A water-softening system includes a filter device including filter units that are provided in at least some of a plurality of supply channels arranged in parallel to supply raw water to a consumption site and that remove at least part of ionic matter contained in supplied raw water by electro-deionization and discharge soft water containing less ionic matter than the raw water, a plurality of supply valves provided in the plurality of supply channels to open or close the supply channels, and a processor connected to the filter device and the plurality of supply valves. The processor determines whether water is supplied to the consumption site and controls at least one of the plurality of supply valves to remain open to maintain a state in which water is allowed to be supplied to the consumption site, when it is determined that no water is supplied to the consumption site.
