Document Type and Number:
WIPO Patent Application WO/2015/114889
Kind Code:
A1
Abstract:
An installation surface for installation of a device for cleaning and bacteria elimination and the device itself are maintained hygienically.
A cleaning device is provided with a cleaning unit (6), a disinfecting unit (1), a rinsing unit (2), and an installation surface (4) on which the cleaning unit (6), the disinfecting unit (1), and the rinsing unit (2) are installed. The installation surface (4) is constituted of a photocatalytic material fabricated by: (1) a step for forming titanium nitride on the surface of titanium material by heat treatment in an ammonia atmosphere or a nitrogen gas atmosphere wherein the heating temperature is 750°C or greater; (2) a step for carrying out anodic oxidation on the titanium material obtained in step (1), whereon titanium nitride has been formed on the surface, by applying a voltage of 10 V or greater in an electrolyte not having an etching action for titanium and forming an oxide coating of titanium; and (3) a step for carrying out heat treatment of the titanium material obtained in step (2), whereon the oxide coating of titanium has been formed on the surface, in an atmosphere selected from an air atmosphere, an atmosphere wherein oxygen gas and nitrogen gas are mixed, or an oxygen gas atmosphere at a temperature of 400°C or greater.
