The water droplets removed from the hands by the drying process contain a considerable amount of dirt and dirt components such as organic substances and fats of the hands, but the water repellency is also present on the inner surface of the drain pipe 9 and the inner surface of the water receiving portion 10. Since it is provided, such dirt components are prevented from adhering and accumulating. In addition, water repellency is also applied to a portion near the hand insertion port 1 of the front panel 5 where water droplets, splashes and the like are likely to adhere.
Since the droplets 4 are provided, the water droplets and splashes are not repelled and adhere to the water droplets. Therefore, it is possible to prevent the water droplets from capturing and accumulating dust in the air. Therefore, it is possible to prevent the contamination components from adhering and accumulating on the water receiving portion 4 and the front surface, and it is possible to provide a hand-drying device that is easy to clean and requires less cleaning, and has good maintainability.

Thereby, the base material B and the water-repellent material A
And a water repellent 14 having a long lasting water repellent effect, which does not cause peeling or the like, can be provided, and can withstand long-term use. PBT resin as base material B,
A resin such as a PET resin or a PPS resin or a sheet metal can be used. As the water-repellent material A, a fluorine resin or a silicone resin can be used.

Specific Example 2 As shown in FIG. 3, when the surface of the portion requiring the water repellent 14 is solidified, a process of immersing in a liquid repellent material of a water repellent, impregnating the liquid, and fixing the material is performed. By dipping and impregnating the substrate B in the liquid repellent material A which exhibits water repellency, a uniform water repellent film thickness can be generated,
Further, since the water-repellent material A can be fixed even at the portion 22 that has entered the base material B, substantially uniform water-repellency 14 can be imparted to the entire part of the part requiring the water-repellent material 14. As the base material B and the water-repellent material A, basically the same materials as those in the first embodiment can be adopted, but as the base material B, a PP resin, an ABS resin, or the like can also be adopted.

Specific Example 3 As shown in FIG. 4, this is a method in which the entire part constituting the portion requiring the water repellency 14 is formed of the water repellent material A having the water repellency.

As described above, the adhesion of the dirt component can be easily removed by reducing the contact angle θ to 50 degrees or less as shown in FIG. That is, instead of the water repellent 14, the hydrophilic 2
3 is the hand drying device according to the second embodiment. By imparting the hydrophilicity 23, water permeates between the portion where the dirt and the water droplets hit, and the effect of raising the dirt is obtained. Even if dirt and dirt components such as organic matter and hand fat contained in the water droplets removed from the hands by the drying process once adhere to the water receiving portions 4 and 10, they are lifted up by the water, so that they are washed away with water. Can be easily removed. Therefore, the cleaning property is good and the cleaning frequency is small, and the maintenance property is improved.

Next, some specific examples for imparting the hydrophilicity 23 will be described. Specific example 1. As shown in FIG. 8, a process of applying and fixing a hydrophilic material C having hydrophilicity to the surface of a portion requiring the hydrophilicity 23 is performed. By adopting this method, the hydrophilicity 23 can be easily and inexpensively provided, and an effect of floating dirt can be obtained. As the hydrophilic material C having hydrophilicity, a material based on a titanium oxide photocatalyst or a polyurethane resin is used. By using titanium oxide having a disinfecting effect as the titanium oxide photocatalyst, not only the removal of dirt but also the disinfecting effect can be obtained. Further, the polyurethane resin has a high self-purifying property and can remove stains with a small amount of water.

Specific Example 2 As shown in FIG. 9, a process of baking and fixing a hydrophilic material C having hydrophilicity to the surface of a portion requiring hydrophilicity 23 is performed. That is, the hydrophilic material C is sprayed or adhered to the surface of the base material B where the hydrophilicity 23 is required.

Specific Example 3 As shown in FIG.
Is performed by dipping in a liquid hydrophilic material C that shows hydrophilicity when solidified on the surface of the portion that needs to be impregnated and fixed.
By dipping and impregnating the base material B in a liquid hydrophilic material C showing hydrophilicity, it is possible to form a uniform hydrophilic film thickness. Can be fixed, so that substantially uniform hydrophilicity 23 can be imparted to the entire part of the part requiring the hydrophilicity 23. Substrate B
As for the above, a PP resin, an ABS resin or the like can be widely used.

Specific Example 4 As shown in FIG.
This is a method of forming the entire part constituting the portion requiring the above with a hydrophilic material C having hydrophilicity. By adopting this method, not only the surface but also the whole part has the hydrophilicity 23. Even if the surface has a large scratch due to cleaning or the like, the hydrophilicity 23 is present inside the part. It has no significant effect on sexual effects.

Specific Example 5 As shown in FIG.
In the process of forming the parts constituting the parts requiring
In this method, a composite material in which a hydrophilic material C is mixed with a material to be used is formed, and the component is formed using the composite material.
