Abstract

A deodorizing and sterilizing dryer can readily provide deodorization, sterilization, and mold prevention for various goods, such as shoes, by supplying a deodorizing and sterilizing air stream. The deodorizing and sterilizing dryer includes, at one end, an outlet and, internally, a heater and a fan. Air that is heated by the heater is forced along an air stream path, which lies between the heater and the outlet, and contacts a columnar ceramic body that is impregnated with an acid solution and a columnar ceramic body that is impregnated with an alkaline chlorine dioxide solution. Both ceramic bodies have a plurality of lengthwise through holes, so as to supply deodorizing and sterilizing air that contains chlorine dioxide gas.

Claims

1. A deodorizing and sterilizing dryer comprising:

a housing having an outlet;

a heater and a fan arranged within said housing so that air heated by said heater is forced, by said fan, along an air stream path which lies between said heater and said outlet;

a first ceramic body impregnated with an acid solution; and

a second ceramic body impregnated with an alkaline chlorine dioxide solution,

said first and second ceramic bodies being positioned along said air stream path downstream of said heater and fan for receiving the heated air forced along the air stream path and for supplying warm air that contains chlorine dioxide gas to said outlet, said ceramic bodies being positioned such that said first ceramic body is adjacent said heater and said second ceramic body is adjacent said outlet.

2. A deodorizing and sterilizing dryer according to claim 1, wherein said first and second ceramic bodies are detachably mounted in said housing.

3. A deodorizing and sterilizing dryer according to claim 1, further comprising an acid solution supply device coupled to said first ceramic body for supplying the acid solution thereto.

4. A deodorizing and sterilizing dryer according to claim 3, wherein said acid solution supply device is detachably mounted on said housing.

5. A deodorizing and sterilizing dryer according to claim 1, further comprising an alkaline chlorine dioxide solution supply device coupled to said second ceramic body for supplying the alkaline chlorine dioxide solution thereto.

6. A deodorizing and sterilizing dryer according to claim 5, wherein said alkaline chlorine dioxide solution supply device is detachably mounted on said housing.

7. A deodorizing and sterilizing dryer according to claim 1, wherein at least one of said ceramic bodies is made of an alkaline ceramic material.

8. A deodorizing and sterilizing dryer according to claim 7, wherein said alkaline ceramic material contains at least one material selected from a group consisting of animal bone powder, shell powder, limestone powder, and coral powder.

9. A deodorizing and sterilizing dryer according to claim 7, wherein said alkaline ceramic material contains animal bone powder.

10. A deodorizing and sterilizing dryer according to claim 7, wherein said alkaline ceramic material contains at least one ceramic selected from a group consisting of silica gel, alumina, and zeolite.

11. A deodorizing and sterilizing dryer according to claim 1, wherein said acid solution contains citric acid.

12. A deodorizing and sterilizing dryer according to claim 1, wherein said acid solution is a citric acid solution and said citric acid solution is at a pH between 2 and 5.

13. A deodorizing and sterilizing dryer according to claim 1, wherein the chlorine dioxide concentration of said chlorine dioxide solution that is used to impregnate said second ceramic body is 500 ppm to 3000 ppm.

14. A deodorizing and sterilizing dryer according to claim 1, wherein at least one of said first and second ceramic bodies is columnar in shape, said columnar shaped ceramic body having a longitudinal dimension, and wherein said dryer further includes a hollow pipe having a perforated pipe wall inserted into said at least one of said ceramic bodies parallel to said longitudinal dimension.

15. A deodorizing and sterilizing dryer according to claim 14, wherein a first frame member, on which is installed a plurality of said columnar shaped ceramic bodies impregnated with said acid solution to form first ceramic bodies, is positioned adjacent to the heater, and a second frame member and a third frame member, on each of which is installed a plurality of said columnar shaped ceramic bodies impregnated with said alkaline chlorine dioxide solution to form second ceramic bodies, are positioned adjacent to the outlet, so that said first, second, and third frame members and said ceramic bodies intersect an air stream of said air stream path.

16. A deodorizing and sterilizing dryer according to claim 1, wherein the shape of at least one of said first and second ceramic bodies is columnar, said at least one of said ceramic bodies having a pair of ends, and wherein hollow pipes are inserted into the ends of said at least one of said ceramic bodies and are connected by a through hole provided in said ceramic body.

17. A deodorizing and sterilizing dryer according to claim 1, further defined as a deodorizing and sterilizing air towel dryer.

18. A deodorizing and sterilizing dryer according to claim 1, wherein at least one of said first and second ceramic bodies has a columnar shape, said columnar shaped ceramic body having a longitudinal dimension and wherein said columnar shaped ceramic body has a plurality of longitudinal through holes.

19. A deodorizing and sterilizing dryer according to claim 18, wherein a plurality of identically shaped, longitudinal through holes are arranged in said at least one of said ceramic bodies.

20. A deodorizing and sterilizing dryer according to claim 18, wherein said plurality of longitudinal through holes includes a central longitudinal through hole that has a given diameter and which is positioned in the center of said columnar shaped ceramic body, and a plurality of longitudinal through holes that have a diameter smaller than said central through hole, which are positioned around said central through hole.

21. A deodorizing and sterilizing dryer according to claim 1, wherein at least one of said first and second ceramic bodies has a columnar shape.

22. A deodorizing and sterilizing dryer according to claim 1, wherein at least one of said ceramic bodies is columnar, and a supply groove for said acid solution or said chlorine dioxide solution, respectively, is formed around the circumference of said columnar ceramic body.

23. A deodorizing and sterilizing dryer according to claim 1, wherein said first ceramic body that is impregnated with said acid solution is securely coupled to said second ceramic body that is impregnated with said alkaline chlorine dioxide solution.

24. A deodorizing and sterilizing dryer according to claim 23, wherein paper and/or non woven fabric is wrapped around said first and second ceramic bodies to securely couple said first ceramic body to said second ceramic body.

25. A deodorizing and sterilizing dryer according to claim 1, further defined as a dryer for deodorizing or sterilizing a product, or preventing mold on a product.

26. A deodorizing and sterilizing dryer according to claim 1, further comprising a plurality of hollow shoe insertion members, each of which has a plurality of small holes, said shoe insertion members communicating with said outlet of said housing.
