Abstract

A sanitation apparatus of this invention is arranged such that a far-infrared ray emitting member (5) made of ceramics, metal oxide or the like is provided to emit far-infrared rays to prevent proliferation of bacteria or to sterilize objects (1, 11, 12, 15, 19) to be kept in a sanitized condition, wherein the far-infrared ray emitting member is heated to emit far-infrared rays which irradiate the object so that proliferation of bacteria is prevented or bacteria is sterilized, and in which a temperature of the far-infrared ray emitting member is kept in a range of about 30° C. to 60° C. so as to prevent a temperature of the object from being increased too much. Thus, the apparatus can be made compact in size and inexpensive, and heating energy can be saved. Also, the application field of the apparatus can be extended, and a bad influence of temperature exerted upon the objects such as when the objects are burned can be prevented, and a risk that the user will be burned by the objects heated too much can be avoided.

Claims

1. Apparatus for sanitizing objects comprising a far-infrared ray emitter made of material selected from ceramic, metal oxide and mixtures thereof, means for locating said far-infrared ray emitter in close proximity to the object to be sanitized and heating means for maintaining the far-infrared emitter at a temperature between 30 degrees and 49 degrees centigrade so as to avoid overheating said object and preventing growth of bacteria thereon.

2. The apparatus according to claim 1, wherein said objects are contained in a surrounding enclosure made of material not pervious to infrared radiation and the far-infrared emitter is located on at least one wall.

3. A method for sanitizing objects comprising the steps of providing a far-infrared emitter made of material selected from ceramic, metal oxide and mixtures thereof, locating said emitter in close proximity to the object to be sanitized and maintaining the emitter at a temperature of between 30 degrees and 49 degrees centigrade while irradiating the object.
