Abstract

The invention provides an apparatus for laundering and treating garments or fabrics with an oxidizing agent. The apparatus includes a housing having a chamber containing a barrel mounted for rotation. A door is provided for placing the garments or fabrics into the chamber. Associated with the housing is a venturi mixer for introducing an oxidizing gas and a liquid into the chamber and a value for removing liquid from the chamber. Controls are is provided to selectively permit a washing, extracting and abrading cycle.

Claims

1. An apparatus for laundering and selectively treating a garment or fabric with an oxidizing gas in combination with a liquid or steam which comprises:

a housing having a chamber, said chamber having a barrel mounted for rotation therein,

means associated with said barrel for rotating said barrel in said chamber,

door means on said housing for placing said garment or fabric into said chamber,

means associated with said housing for selectively introducing either a controlled amount of oxidizing gas and steam into said chamber or a controlled amount of oxidizing gas and an aqueous liquid into said chamber, said means having a venturi which mixes said oxidizing gas and said liquid, and

pipe means associated with said chamber for recirculating an oxidizing gas through and into said chamber,

means for removing liquid from said chamber, and

control means for selectively causing a cycle of a laundering operation to be performed.

2. The apparatus of claim 1 wherein said barrel is apertured.

3. The apparatus of claim 1 wherein said barrel is provided on its interior with means for abrading said garment or fabric.

4. The apparatus of claim 1 wherein said means for rotating said barrel comprises a variable motor.

5. The apparatus of claim 1 wherein said venturi is associated with an ozone generator.

6. The apparatus of claim 1 wherein said means for removing liquid from said chamber is associated with said venturi whereby liquid removed from the chamber is recirculated to said chamber through said venturi.

7. The apparatus of claim 1 wherein said means for introducing steam liquid into said chamber comprises a steam jet.

8. The apparatus of claim 1 wherein said means for introducing an aqueous liquid into said chamber comprises a water valve.

9. The apparatus of claim 1 including means for monitoring the amount of oxidizing gas in said chamber.

10. The apparatus of claim 1 including means for controlling the liquid level in said chamber.

11. The apparatus of claim 1 including means for heating said chamber.

12. An apparatus for laundering and selectively treating a garment or fabric with ozone in an aqueous liquid or steam environment which comprises:

a housing having a chamber, said chamber having an apertured barrel mounted for rotation therein;

motor means associated with said barrel for rotating said barrel in said chamber;

door means on said housing for placing said garment or fabric into said chamber;

means associated with said housing for selectively introducing either a controlled amount of liquid and ozone or selectively introducing steam and ozone into said chamber, said means having a venturi which mixes said ozone with said liquid;

pipe means associated with said chamber for circulating ozone into and through said chamber;

means for removing liquid from said chamber;

means for monitoring the amount of ozone within said chamber;

means mounted for heating said chamber, and

control means for selectively causing a laundering operation to be performed.

13. The apparatus of claim 12 wherein said barrel is provided with abrading means.

14. The apparatus of claim 12 including means for recirculating the liquid removed from said chamber back into said chamber.

15. The apparatus of claim 12 wherein said motor means comprises a variable speed motor.

16. The apparatus of claim 12 including means for controlling the temperature control with said chamber.
