Abstract:
An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system and a recirculation loop to the dilution reservoir for enhanced mixing of the dilute concentrate. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.
Abstract:
A washing machine appliance and a method for regulating ozone within the same are provided. The method includes activating an ozone generation system of the washing machine appliance in order to initiate a flow of ozonized water into a tub of the washing machine appliance and measuring an amount of ozone within an exhaust conduit of the washing machine appliance with an ozone sensor. Based at least in part on the amount of ozone within the exhaust conduit, various steps can be taken to regulate the amount of ozone within a wash chamber of the washing machine appliance.
Abstract:
An electrolysis device is disclosed for producing alkaline water from water including an electrolysis vessel, a positive electrode, a negative electrode, a bipolar membrane element, and at least one cation exchangeable membrane within the electrolysis vessel. The bipolar membrane element has a cation exchangeable side and an anion exchangeable side, the cation exchangeable side being closer to the negative electrode than the anion exchangeable side. The at least one cation exchangeable membrane is arranged between the anion exchangeable side of the bipolar membrane element and the positive electrode, so as to define an alkali chamber between the bipolar membrane element and the cation exchangeable membrane. An ionic exchange resin is associated with the vessel, whereby flow of the water though the vessel and the ionic exchange resin produces alkaline water in the alkali chamber. Various options and modifications are possible. A related washing machine such as a dishwasher is also disclosed.
Abstract:
In an ion elution unit, a drive circuit applies a voltage between electrodes to elute metal ions from the electrodes. Polarities of the electrodes are reversed cyclically with a voltage application halt period placed in-between. A current detection circuit detects the current flowing between the electrodes. A check of operation of the current detection circuit is carried out before the application of a voltage to the electrodes is started. The operation of the current detection circuit is started when a predetermined period of time passes after the application of a voltage to the electrodes is started.
Abstract:
Prior to adding detergent or chelant, the conductivity of water in a washing chamber is measured. The maximum concentration of hard water ions that could correspond to the measured conductivity is determined, i.e., it is assumed that all of the conductivity is from calcium and/or magnesium ions in the water even though other ions may in fact be contributing to the measured conductivity. Enough chelating agent is added to the chamber to sequester this maximum concentration of hard water ions and the conductivity is measured again. Using the two conductivity measurements, the actual concentration of hard water ions is determined. A chelant factor based on the actual concentration of hard water ions is then used to determine the amount of chelant to be added for subsequent wash cycles to sequester all of the hard water ions.
Abstract:
A washing machine includes a colloidal silver maker and a detergent feeder which are integrated with each other, thus enhancing assembility and reliability of the washing machine. The colloidal silver maker includes a silver ion casing, a lid, and a pair of silver plates. An outlet pipe and a connecting part are provided on predetermined portions of the silver ion casing. The outlet pipe is integrated with an inlet of the detergent feeder, and the connecting part integrally connects the colloidal silver maker to the detergent feeder. Thus, the colloidal silver maker is integrated with the detergent feeder while the silver ion casing of the colloidal silver maker communicating with the detergent feeder. The silver plates are placed in the silver ion casing while being supported by the lid. Further, at least one spacing projection is upwardly projected from a bottom of the silver ion casing to be provided between the silver plates.
Abstract:
The present disclosure generally provides systems and methods of controlling an ion concentration in water, for example, a silver ion concentration. The method of depositing ions in the water includes determining a conductivity level of the water using a reference probe. A power level based on the determined conductivity level is also determined. Power is applied to a deposition probe corresponding to the determined power level using a first electrical circuit, and a concentration of ions are deposited in the water.

Abstract:
An ion elution unit generates metal ions by applying a voltage between electrodes. Terminals are formed integrally to the electrodes. An interval between the electrodes becomes narrower from an upstream side to a downstream side with respect to a water current flowing through an inside of a casing of the ion elution unit. Terminals that are so laid as to run from the electrodes out of a casing of the ion elution unit are disposed on an upstream side with respect to a water current flowing through an inside of the casing.

A water treatment unit mounted in a washing machine, comprising a cartridge type case. An inflow port and an outflow port connected to a water supply port and a water receiving port formed in the washing machine are formed in the case. An electrode eluting metal ions in water by energization is disposed in the case and a connector part for supplying power to the electrode is disposed on the outer surface of the case. The case is formed slender and the inflow port and the outflow port are formed in the case, concentrically to each other, at positions near one end thereof and the connector part is disposed at a position near the other end.
