Abstract

A method and apparatus for sterilizing and disinfecting bedclothes. The method includes preparing a sterilizing room defined by a cover; placing bedclothes into the sterilizing room; and exposing the bedclothes to ultraviolet rays and ozone generated by a generator in communication with the sterilizing room. The apparatus includes a generator for generating ultraviolet rays and ozone and a cover for defining a sterilizing room to accommodate the bedclothes.

Claims

1. A method comprising the steps of:

preparing a sterilizing and disinfecting room using a sterilizing and disinfecting apparatus comprising a foldable cover attached to a compartment, the foldable cover being supportable by a stay for maintaining an interior space within the foldable cover;

placing bedclothes in the sterilizing and disinfecting room; and

exposing the bedclothes to ultraviolet rays and ozone.

2. The method as claimed in claim 1, wherein the sterilizing and disinfecting apparatus comprises an ultraviolet ray and ozone generator, the ultraviolet ray and ozone generator being used in the step of exposing the bedclothes to ultraviolet rays and ozone.

3. The method of claim 1, wherein the step of preparing a sterilizing and disinfecting room comprises developing the foldable cover from a folded condition into a developed condition in which the foldable cover defines the sterilizing and disinfecting room.

4. An apparatus comprising:

a cover defining a sterilizing and disinfecting room, said cover including an open area for accessing the sterilizing and disinfecting room and means for opening and closing said open area, the open area being sized and configured for introducing bedclothes into the sterilizing and disinfecting room; and

a generator for generating ultraviolet rays and ozone, and directing the ultraviolet rays and ozone into the sterilizing and disinfecting room, the generator having a compartment formed therein and a lid for closing the compartment, the cover being attached to the compartment and foldable for accommodation in the compartment.

5. The apparatus as claimed in claim 4, wherein said means for opening and closing said open area comprises a zipper adapted to close the open area to prevent outflow of ozone.

6. The apparatus as claimed in claims 4, wherein said cover is made of a plastic film which is sealed hermetically to prevent outflow of the ozone.

7. The apparatus as claimed in claim 4, wherein said cover is made of a foldable coated fabric sheet which is sealed hermetically to prevent outflow of the ozone.

8. The apparatus of claim 7, wherein the cover includes a coating which prevents outflow of the ozone.

9. The apparatus as claimed in claim 4, wherein said generator for generating ultraviolet rays and ozone includes a stay for maintaining the space on the inside of said sterilizing and disinfecting room.

10. The apparatus as claimed in claim 4, further comprising a support for bedclothes placed in said sterilizing and disinfecting room, said support allowing multidirectional ozone access to said bedclothes.

11. The apparatus as claimed in claim 10, further comprising a reflection mirror which irradiates the ultraviolet rays to said bedclothes when said bedclothes are placed on said support.

12. The apparatus as claimed in claim 4, wherein said generator for generating ultraviolet rays and ozone includes a fan for circulating the ozone in said sterilizing and disinfecting room.

13. The apparatus as claimed in claim 4, wherein said means for opening and closing said open area comprises a fastening string adapted to close the open area to prevent outflow of ozone.

14. The apparatus of claim 4, wherein bedclothes are isolated in the sterilizing and disinfecting room.
