Benefits of technology

[0009]One aspect of the present invention is to provide an electrolytic mist generating device including an electrolytic cell, electrode parts where a pair of positive pole and negative pole are arranged in parallel and opposed to one another in the electrolytic cell, a piezoelectric element that generates mist of electrolytic water generated inside the electrolytic cell, a water supply device that supplies water into the electrolytic cell, a discharging device that discharges the mist from the electrolytic cell, and a control circuit that controls operation steps of the electrolytic cell, wherein in an electrolysis step, a voltage that does not permit the mist to be generated is applied to the piezoelectric element to generate a water column. Since in the electrolysis step, by applying to the piezoelectric element the voltage that does not permit the mist to be generated to generate the water column, the electrolysis in the electrode parts is performed by a batch method, desired high-concentration metal ion water can be stably and continuously obtained in accordance with an electrolytic current value and an electrolysis time. By applying to the piezoelectric element the voltage that does not permit the mist to be generated to generate the water column, aqueous solution during the electrolysis step can be efficiently circulated, so that a harmful effect such as nonuniformity of the solution accompanying the batch method and the like can be prevented. The piezoelectric element can have both the mist generation function and the water circulating function in the electrolytic cell.

Problems solved by technology

Most of the metal ion thus goes to waste.
Therefore, a great amount of electrolytic water is needed for obtaining the Ag ion that brings about the antibacterial effect to the washed clothing.
In this case, since a piezoelectric element cannot generate so much mist per unit time, processing time becomes very long.

embodiment 1

[0050]FIG. 1 is a schematic configuration view of an electrolytic mist generating device according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view of FIG. 1, and FIG. 3 is a top view of electrode parts and a piezoelectric element.

[0051]Two sheets of electrode parts 2 are arranged in parallel with respect to a bottom surface of electrolytic cell 1. Electrode parts 2 are specifically Ag plates of 2 cm×5 cm having a thickness of 1.2 mm, and spaced from each other at a distance of 8 mm. Terminal part 2a for applying a voltage through rubber packing 3 from each of electrode parts 2 is drawn outside electrolytic cell 1. Each of electrode parts 2 is fixed to the bottom surface of electrolytic cell 1 by rubber packing 3.

[0052]Piezoelectric element 4 is arranged adjacent to a position where a generated water column is formed by a water flow passing between two sheets of electrode parts 2. In a bottom portion, there is provided recessed part 5 having a predetermined...

embodiment 2

[0077]In the present embodiment, an electrolytic mist generating device resembles that of the first embodiment, and thus, a detailed description of the entire device is omitted. FIG. 7 is a schematic configuration view of the electrolytic mist generating device in a second embodiment of the present invention.

[0078]In discharging device 70, a blowing fan is not provided, but intake port 42 is provided. A configuration is adapted such that the inside of electrolytic cell 1 is put into a negative pressure state to take in air from intake port 42 and that the generated mist is discharged outside of electrolytic cell 1. When a description is given to the washing machine shown in FIG. 4, by operating blower 19, a negative pressure force acts on the mist outlet 8 side of electrolytic mist generating device 40 so that the mist generated inside electrolytic cell 1 is directed to the inner tub 14 side.

embodiment 3

[0079]Also, in the present embodiment, an electrolytic mist generating device resembles that of the first embodiment, and thus, a detailed description of the entire device is omitted. As a different point from the first embodiment, operation of the electrolytic mist generating device is described. FIG. 8 is a system flowchart showing the operation of the electrolytic mist generating device.

[0080]Here, after the drainage step, a cleaning step is added. Specifically, after the drainage step, service water is supplied from water supply and drain port 9 up to a predetermined water level. Once the predetermined water level is sensed by the water level sensor, the switching valve is turned to a drainage direction to discharge the stored water at a time. This allows electrode part 2 surfaces used in the electrolysis, an electrolytic cell 1 inner surface or a piezoelectric element 4 surface to be cleaned in each use. Accordingly, even when a use interval of the electrolytic mist generating ...

Description

TECHNICAL FIELD[0001]The present invention relates to an electrolytic mist generating device for disinfecting and antibacterial effects, and a washing machine using the same.BACKGROUND ART[0002]In recent years, technology for subjecting laundry to antibacterial treatment during washing has been proposed. For example, Patent Literature 1 discloses an electric washing machine with an ion generator that generates a metal ion having bacteriocidal capacity. Patent Literature 2 discloses a washing machine with an Ag ion adding unit that adds an Ag ion to cleaning water. Patent Document 3 discloses a washing machine that water with an Ag ion eluted is sprayed onto clothing in a shower-like manner. Patent Literature 4 discloses a drier that squirts, on laundry, mist of water with an Ag ion eluted.[0003]Typically, the elution of a metal ion is performed by electrolysis. Applying a voltage between electrodes for electrolysis allows the metal ion to be eluted from the anodic electrode in accor...
