Abstract

A system and process for drying a shoe, for example a leather shoe comprising a fan operable to produce an air flow, a heating element and at least one duct having at least one outlet, which is adapted to direct a portion of the air flow into a shoe. Additionally, the shoe drying system provides a drying effectiveness of at least 70 g/hr within the first hour of drying.

Claims

1. A system for drying a shoe, comprising:

a fan operable to produce an air flow;

a heating element;

at least one duct having at least one outlet configured to be positioned within the shoe and adapted to direct at least a portion of the air flow into the shoe, and said duct further comprising at least one tube extending from the duct and configured to be positioned within the shoe;

wherein said system provides a drying effectiveness of at least 70 g/hr within the first hour of drying.

2. The system of claim 1, wherein said drying effectiveness is between 70 g/hr and about 120 g/hr.

3. The system of claim 1, wherein the temperature of the airflow at said outlet is less than about 55°

C.

4. The system of claim 1, wherein the airflow is between about 500 fpm and about 4000 fpm.

5. The system of claim 1, further comprising a vented bag for receiving a shoe and said duct.

6. The system of claim 1, further comprising a second duct for directing at least a portion of the air flow into a second shoe, said other duct having an outlet.

7. The system of claim 1, further comprising a turbulence generating device at least partially within said duct.

8. The system of claim 7, wherein said turbulence generating device comprises a blade.

9. The system of claim 7, further comprising a plurality of tubes extending from said duct.

10. The system of claim 1, wherein the tube is configured to inflate upon airflow entering the tube.

11. The system of claim 1, wherein said tube is configured to absorb retained water from the interior surface of the shoe.

12. The system of claim 1, further comprising a shield configured to at least partially surround the duct and each of the tubes and configured to be movable along the longitudinal axis of the duct.

13. The system of claim 1, wherein the tube further comprises an outlet for directing at least a portion of the airflow into the shoe.

14. The system of claim 13, wherein the outlet of the tube is directed toward the toe end of the shoe.

15. A system for drying a shoe resting in an upright position, comprising:

a fan operable to produce an air flow;

a heating element;

at least one duct adapted to direct at least a portion of the airflow into a shoe, said duct having at least one outlet therein; and

a vented bag having an inflated state upon operation of said fan, said vented bag having a proximal end for receiving said duct, a distal end opposite said proximal end, and a plurality of apertures formed adjacent said distal end of said bag, said apertures being positioned above the toe of a shoe to be dried when the vented bag is in said inflated state.

16. The system of claim 15, wherein said apertures are of sufficient size to maintain said vented bag in an inflated state upon operation of said fan.

17. The system of claim 15, further comprising a at least one tube extending from the duct and configured to contact an interior surface of the shoe.

18. A system for drying a shoe comprising;

a fan operable to produce an airflow;

a heating element;

a duct for directing the air flow into a shoe, said duct having at least one outlet therein; and

a fixed-bladed device positioned within a portion of said duct for generating turbulent airflow along substantially the interior length of a shoe.

19. The system of claim 18, wherein the fixed-bladed device comprises a planar portion and plurality of outwardly flanges extending from the planar portion and forming an obtuse angle therewith.

20. A process for drying a shoe, comprising the steps of:

providing a shoe;

providing a drying system comprising a fan operable to produce an air flow, a heating element, a duct having an outlet, and a tube extending from said duct and configured to be positioned within the shoe, wherein said drying system has a drying effectiveness of at least about 70 g/hr;

inserting said duct and tube into said shoe; and

directing an air flow to the interior of said shoe.

21. The process of claim 20, wherein said step of supplying an airflow continues for less than one hour.

22. The process of claim 20, wherein said drying system further comprises a turbulence generating device.

23. The process of claim 22, wherein said turbulence generating device comprises a blade.

24. The process of claim 20, further comprising a vented bag for receiving said shoe and said duct having an airflow exiting said bag.

25. The process of claim 24, wherein said airflow exiting said bag has a relative humidity of about 20%.

26. The process of claim 20, further comprising the step of immersion washing said shoe prior to said supplying step.

27. A process for drying a shoe, comprising the steps of:

providing a shoe;

immersion washing said shoe;

providing a drying system comprising a fan operable to produce an air flow, a heating element, a duct having an outlet and a fixed-bladed device positioned within a portion of said duct for generating turbulent airflow;

inserting said duct into said shoe;

directing said airflow to the interior of said shoe; and

maintaining said airflow to provide a drying effectiveness of at least 70 g/hr within the first hour of drying.
