Membrane-electrode assembly, electrolytic unit using the same, electrolytic water ejecting apparatus, and method of sterilization
View Patent ↗The present invention provides: a membrane-electrode assembly having a first electrode having a shape of a rod-form or a cylindrical-form, a strip-form diaphragm covering the periphery of the first electrode, and a second electrode disposed on a surface of the strip-form diaphragm; an electrolytic unit containing the membrane-electrode assembly; an electrolytic water ejecting apparatus containing the electrolytic unit; and a method of sterilization using the membrane-electrode assembly.
1. A membrane-electrode assembly comprising:
a first electrode having a shape of a rod-form or a cylindrical-form;
a strip-form diaphragm covering the periphery of the first electrode; and
a second electrode disposed on a surface of the strip-form diaphragm,
wherein the strip-form diaphragm spirally covers the periphery of the first electrode.
2. The membrane-electrode assembly of claim 1 ,
wherein the strip-form diaphragm covers the periphery of the first electrode so as to form a space between parts of the diaphragm.
3. The membrane-electrode assembly of claim 1 , wherein the strip-form diaphragm includes recesses and protrusions.
4. The membrane-electrode assembly of claim 1 , wherein at least one of the first electrode and the second electrode includes openings formed therethrough.
5. The membrane-electrode assembly of claim 1 , wherein the strip-form diaphragm comprises an ion-exchange membrane.
6. The membrane-electrode of claim 1 , wherein the second electrode spirally covers a periphery of the strip-form diaphragm.
7. An electrolytic unit comprising:
a membrane-electrode assembly comprising:
a first electrode having a shape of a rod-form or a cylindrical-form;
a strip-form diaphragm covering the periphery of the first electrode; and
a second electrode disposed on a surface of the strip-form diaphragm,
wherein the strip-form diaphragm spirally covers the periphery of the first electrode;
a tube, the membrane-electrode assembly being fixed in the tube; and
an electric supply terminal connected to at least one of the first electrode and the second electrode in the tube.
8. An electrolytic water ejecting apparatus comprising:
a vessel containing a raw water;
the electrolytic unit according to claim 7 ;
a head to eject an electrolytic water prepared by electrolyzing the raw water with the electrolytic unit.
9. A method of sterilization with an electrolytic water, the method comprising:
electrolyzing a raw water with a membrane-electrode assembly comprising:
a first electrode having a shape of a rod-form or a cylindrical-form;
a strip-form diaphragm covering the periphery of the first electrode; and
a second electrode disposed on a surface of the strip-form diaphragm to produce a electrolytic water; and
ejecting the electrolytic water to a substance to be sterilized.
