A method of operating a facility having beds involves removing bedding (such as pillows, bedspreads, and blankets) from a bed of a facility after departure of a user and irradiating bedding with narrow spectrum radiation to obtain sanitary bedding. The bed is then made up with the sanitized bedding.

A method of operating a facility having beds involves removing bedding (such as pillows, bedspreads, and blankets) from a bed of a facility after departure of a user and irradiating bedding with narrow spectrum radiation to obtain sanitary bedding. The bed is then made up with the sanitized bedding. A sanitizer to effect the method comprises an irradiation chamber and at least one narrow spectrum light for emitting into the chamber. A bedding support is mounted for reciprocation within said chamber between a first terminal position proximate a base of the chamber and a second terminal position part way between the base of the chamber and a top of the chamber. With this arrangement and the top of the chamber acting as a backstop, the sanitizer is particularly suited for sanitizing pillows which may be placed on the bedding support and repeatedly compressed as the bedding support reciprocates.

What is claimed is: 1. A method of operating a facility having beds, comprising: after departure of a user of a bed of said facility, removing used bedding from said bed; utilizing at least one source of narrow spectrum radiation, irradiating bedding with narrow spectrum radiation while moving said bedding relative to said at least one source of narrow spectrum radiation to obtain sanitized bedding; and making up said bed with said sanitized bedding. 2. The method of claim 1 wherein said sanitized bedding comprises at least one of a blanket, a pillow, and a bedspread. 3. The method of claim 2 wherein said bedspread is a duvet. 4. The method of claim 2 wherein said facility is a hotel. 5. The method of claim 2 wherein said facility is a hospital. 6. The method of claim 2 wherein said facility is an airplane and said bed is a reclinable seat on said airplane. 7. The method of claim 2 wherein said irradiating with narrow spectrum radiation comprises exposing said bedding to ultraviolet radiation. 8. The method of claim 7 further comprising circulating air about said bedding while exposing said bedding to ultraviolet radiation. 9. The method of claim 1 wherein said removing and making-up occurs every time a new user of said bed departs. 10. A method of operating a facility having beds, comprising: after departure of a user of a bed of said facility, removing used bedding from said bed; irradiating bedding with narrow spectrum radiation to obtain sanitized bedding; and making up said bed with said sanitized bedding, wherein said bedding comprises compressible bedding and further comprising repetitively compressing and relaxing said compressible bedding while exposing said compressible bedding to said narrow spectrum radiation. 11. The method of claim 10 wherein said compressible bedding comprises a pillow. 12. The method of claim 11 wherein said compressing compresses said pillow to about one-half a height of said pillow, when uncompressed. 13. The method of claim 10 wherein said irradiating with narrow spectrum radiation comprises exposing said bedding to ultraviolet radiation. 14. The method of claim 13 further comprising circulating air about said bedding while exposing said bedding to ultraviolet radiation. 15. A method of operating a facility having beds, comprising: after departure of a user of a bed of said facility, removing used bedding from said bed; irradiating bedding with narrow spectrum radiation to obtain sanitized bedding; and making up said bed with said sanitized bedding, wherein said bedding comprises a blanket or a bedspread and wherein said exposing said bedding to ultraviolet radiation comprises moving an ultraviolet light along opposite sides of said blanket or bedspread at a stand-off from said blanket or bedspread. 16. The method of claim 15 further comprising draping said blanket or bedspread over a support prior to exposing said bedding to ultraviolet radiation and wherein said exposing said bedding to ultraviolet radiation includes moving an ultraviolet light under said support. 17. The method of claim 15 wherein said irradiating with narrow spectrum radiation comprises exposing said bedding to ultraviolet radiation. 18. The method of claim 17 further comprising circulating air about said bedding while exposing said bedding to ultraviolet radiation. 19. A sanitizer for bedding, comprising: an irradiation chamber; at least one narrow spectrum light for emitting into said chamber; a bedding support mounted for reciprocation within said chamber between a first terminal position proximate a base of said chamber and a second terminal position part way between said base of said chamber and a top of said chamber. 20. The sanitizer of claim 19 wherein said top of said chamber comprises a backstop to impede any bedding on said bedding support from moving above said top of said chamber while said bedding support reciprocates, such that said any bedding is compressed between said reciprocating bedding support and said backstop when said bedding support moves toward said backstop. 21. The sanitizer of claim 18 further comprising a fan for circulating air within said irradiation chamber. 22. The sanitizer of claim 21 wherein walls of said chamber are embossed to impart turbulence to air circulated in said chamber. 23. The sanitizer of claim 22 wherein said bedding support is mounted proximate its periphery on screws that are threaded along a portion of their length in order to define said first terminal position and said second terminal position. 24. The sanitizer of claim 23 wherein each of said screws is threaded with a first spiral thread and a second spiral thread, said first spiral thread meeting said second spiral thread at an inner end of said screw which is part way between said base of said chamber and said top of said chamber, said first spiral thread and second spiral thread arranged such that a direction of tracing that traces said first spiral thread toward said inner end of said screw traces said second spiral thread away from said inner end of said screw. 25. The sanitizer of claim 24 further comprising at least one motor for driving said screws in said direction. 26. The sanitizer of claim 25 wherein said bedding support comprises a lifting assembly surrounding each of said screws, each lifting assembly supported by a thread of said screw so that rotation of said screws in said direction causes said lifting assemblies to trace one of said first spiral thread and said second spiral thread.
