In the hand drying apparatus according to the present embodiment, after performing the hand disinfection process after the hand drying process, when the hand is completely removed from the hand insertion unit 3, the hand detection sensor (not shown). The ejection device 15 is operated for a predetermined time that can be adjusted by the processing of the control circuit 20 and performs a self-cleaning function after a predetermined time that can be adjusted is detected. That is, the cleaning discharge device 15 sends out a certain amount of the cleaning liquid in the tank 21 to the upper and lower cleaning nozzles 16 in the hand insertion section 3. The nozzle 16 is provided so that the cleaning liquid spreads over the entirety of the hand insertion portion 3, and can wash away dirt on the entire inner surface of the hand insertion portion 3.

The cleaning liquid after the cleaning passes from the drain port 4 to the drain pipe 22, passes through the antibacterial activated carbon filter 25, is purified, collected again in the tank 21, and reused. Water separated from the hands during the drying process of the hands also passes through the drainage pipe 4 of the hand insertion section 3, passes through the drainage pipe 22, passes through the antibacterial activated carbon filter 25, is filtered to remove dirt components, is purified, is collected in the tank 21, and is washed in the tank 21. Used as The amount of water stored in the tank 21 is controlled to be within a certain range,
When the water storage volume exceeds a certain level, the drain pipe 29
Is led to the evaporating dish 27 and is subjected to an evaporating process. Also, as shown in FIG. 4, a removable drain tank 30 is provided,
The drain pipe 29 may be connected to the drain tank 30.
The water may be drained directly from 9 to the outside.

For maintenance, it is only necessary to add sodium chloride. If the capacity of the storage tank 31 is increased, the maintenance-free period can be further lengthened. At the time of disposal, it can be neutralized by mixing with alkaline water or harmless by simply mixing with a large amount of water, and there is almost no concern about environmental pollution. Acidic water has a broad bactericidal spectrum and has a bactericidal effect on various bacteria.

After the hand washing, the hand insertion unit 3 after the hand drying process and the disinfecting process are also washed. After a lapse of time, the discharge device 15 for cleaning operates,
The electromagnetic switching valve 37 is initially on the side of the tank 33 containing the alkaline water, and the alkaline water in the tank 33 is discharged from the nozzle 16 into the hand insertion section 3. Then, after a certain time that can be adjusted, the electromagnetic switching valve 37 is switched to the side of the tank 34 containing the acidic water, and the acidic water is discharged from the cleaning nozzle 16 into the hand insertion section 3, and the hand insertion section 3 is discharged. Are washed by a washing action of alkaline water and a sterilizing action of acidic water. Alkaline water and acidic water used for hand washing and washing are mixed in the drain pipe 5 from the drain port 4 of the hand insertion portion 3 and neutralized, so that there is no problem even if drained to the outside.

The alkaline and acidic electrolyzed water generated by the electrolyzed water generating means are mixed in the electrolytic bath 32 and outside the electrolytic bath 32, and the neutralized aqueous solution is used as hand washing water and cleaning solution. You can also. That is, Cl
An electrolyte containing O- ions or HClO- can be obtained from a strong acid to neutral depending on the mixing ratio, and an electrolyte can be made according to the intended use. Other functions are the same as those of the first embodiment.
