Abstract

An invention is provided for a hand drying apparatus for drying and sanitizing hands is disclosed. The hand drying apparatus includes a housing having an air intake opening and a heating element situated within the housing capable of heating air drawn into the hand drying apparatus through the air intake opening. Also located within the housing is an air conduit that is in communication with the air intake opening. Further included is a blower that is capable of drawing an air stream into the air conduit through the air intake opening. An ozone gas generator is in communication with the air conduit that is capable of injecting ozone into the air stream to create an ozonated air stream. In this manner, the blower ejects a heated ozonated air stream out of the hand drying apparatus through the air conduit, whereby a user'"'"'s hands are dried and sanitized.

Claims

1. A hand drying apparatus for drying and sanitizing hands, comprising:

a housing having an air intake opening;

a heating element situated within the housing, the heating element capable of heating air drawn into the hand drying apparatus through the air intake opening;

an air conduit located within the housing, the air conduit in communication with the air intake opening;

a blower capable of drawing an air stream into the air conduit through the air intake opening; and

an ozone gas generator in communication with the air conduit, the ozone gas generator capable of injecting ozone into the air stream to create an ozonated air stream, wherein the blower ejects a heated ozonated air stream out of the hand drying apparatus through the air conduit, whereby a user'"'"'s hands are dried and sanitized.

2. A hand drying apparatus as recited in claim 1, wherein the air conduit forms a portion of a dual air conduit system, each air conduit of the dual air conduit system in communication with the air intake opening.

3. A hand drying apparatus as recited in claim 2, further comprising an additional blower in communication with the dual air conduit system, wherein each air conduit of the dual air conduit system includes a separate blower.

4. A hand drying apparatus as recited in claim 1, wherein the ozone gas generator is a corona discharge device having a cylindrical electrode structure.

5. A hand drying apparatus as recited in claim 1, further comprising a proximity sensor located on the housing, the proximity sensor capable of sensing when a user'"'"'s hands are near the proximity sensor.

6. A hand drying apparatus as recited in claim 5, wherein the proximity sensor actuates a switch that allows power to be provided to the ozone gas generator, and the heating element.

7. A hand drying apparatus as recited in claim 1, further comprising a motor situated within the housing and in mechanical communication with blower, the motor capable of driving the blower.

8. A hand drying apparatus for drying and sanitizing hands, comprising:

a housing having an air intake opening;

a heating element situated within the housing, the heating element capable of heating air drawn into the hand drying apparatus through the air intake opening;

a dual air conduit system having two air conduits, each air conduit in communication with the air intake opening;

two blowers located within the dual air conduit system, wherein each air conduit of the dual air conduit system includes a separate blower, each blower capable of drawing an air stream into the air conduit having the blower through the air intake opening;

a double shafted motor situated within the housing and in mechanical communication with each blower, the double shafted motor capable of driving each blower; and

an ozone gas generator situated within the dual air conduit system, the ozone gas generator capable of injecting ozone into the air stream to create an ozonated air stream, wherein the blowers eject heated ozonated air streams out of the hand drying apparatus through each air conduit of the dual air conduit system, whereby a user'"'"'s hands are dried and sanitized.

9. A hand drying apparatus as recited in claim 8, wherein the ozone gas generator is a corona discharge device having a cylindrical electrode structure.

10. A hand drying apparatus as recited in claim 8, further comprising a switch in electrical communication with the heating element, the double shafted motor, and the gas generator.

11. A hand drying apparatus as recited in claim 10, further comprising a proximity sensor located on the housing and in electrical communication with the switch, the proximity sensor capable of sensing when a user'"'"'s hands are near the proximity sensor.

12. A hand drying apparatus as recited in claim 11, wherein the proximity sensor actuates the switch upon sensing a user'"'"'s hands, wherein the actuated switch allows power to be provided to the heating element, the double shafted motor, and the ozone gas generator.

13. A hand drying apparatus as recited in claim 12, wherein the proximity sensor deactivates the switch upon no longer sensing the user'"'"'s hands near the proximity sensor.

14. A hand drying apparatus as recited in claim 14, wherein the deactivated switch shuts off the heating element, the double shafted motor, and the ozone gas generator.

15. A method for drying and sanitizing hands, comprising the operations of:

activating a heating element, an ozone gas generator, and a blower, wherein the blower creates a heated air stream by drawing air past the heating element;

directing the heated air stream past the ozone gas generator, wherein the ozone gas generator injects ozone into the heated air stream creating a heated ozonated air stream;

ejecting the heated ozonated air stream into a drying space, whereby wet hands situated within the drying space are dried and sanitized.

16. A method as recited in claim 15, further comprising the operation of detecting a user'"'"'s hands located in the drying space utilizing a proximity sensor.

17. A method as recited in claim 16, wherein the proximity sensor actuates a switch that activates the heating element, the ozone gas generator, and the blower upon detecting the user'"'"'s hands in the drying space.

18. A method as recited in claim 17, wherein the proximity sensor deactivates the switch upon no longer sensing the user'"'"'s hands in the drying space.

19. A method as recited in claim 18, wherein the deactivated switch shuts off the heating element, the ozone gas generator, and the blower.
