【Example】

(Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the configuration of the hand drying apparatus of the present embodiment, and FIG. 2 is a sectional view of the same. Reference numeral 4 denotes an electric blower, and the airflow blown by the electric blower 4 passes through a passage 6,
It is guided to the drying room 9. That is, the passage 6 is provided with a plurality of rows of ejection holes 8 for blowing high-speed air from the upper surface of the drying chamber 9 at the end. The lower surface of the drying chamber 9 is connected to the passage 6 '. That is, a plurality of rows of ejection holes 7 are provided also on the lower surface side of the drying chamber. That is, the ejection hole 7 and the ejection hole 8 are formed so as to face each other with the inserted hand 13 interposed therebetween, and are connected to the passage 6 and the passage 6 ′. Reference numeral 11 denotes a suction hole provided in the back of the hand drying chamber 9 and communicates with a return passage 12 connected to the electric blower 4.

The operation of the embodiment will be described below. The airflow generated by the electric blower 4 passes through the passage 6 and the passage 6 ′.
And is guided to the ejection holes 7 and 8. The airflow passing through the ejection holes 7 and 8 becomes a high-speed jet and is blown from the insertion port 10 onto the surface of the wet hand 13 inserted into the drying chamber 9. After the water is blown off from the surface of the wet hand 13 in this manner, the high-speed jet is sucked into the return passage 12 from the suction hole 11 provided at the back of the drying chamber 9. The airflow sucked into the return passage 12 returns to the electric blower 4 and is blown again from the electric blower 4 to the passages 6 and 6 ′. That is, the airflow generated by the electric blower 4 is
The air flows between the drying chamber 9 and the electric blower 4 through the ejection holes 7 and 8. At this time, the flow of the air current is such that the drying chamber 9 is a substantially closed space in which only the front surface is an opening which is the insertion port 10 into which the wet hand 13 is inserted, and a substantially closed space. This is substantially determined by the injection holes 8 and the injection holes 7 provided on the upper surface and the lower surface of the drying chamber 9.

Therefore, there is a low possibility that the germs enter the airflow blown by the electric blower 4, and no germs are sprayed on the hands during drying. Also,
The situation in which the moisture on the surface of the wet hand 12 scatters around due to the drying, and the inefficient situation in which the moisture once separated from the wet hand 13 re-adheres to the surface of the hand do not occur. In other words, the moisture on the surface of the wet hand 13 blown off inside the drying chamber 9 in the substantially closed space travels toward the suction hole 11 in accordance with the above-mentioned substantially determined airflow path.

Further, according to this embodiment, the air flow is generated by the ejection holes 7.
When passing through the ejection hole 8, the ejection hole 7 and the ejection hole 8 are narrow passages, which compress the airflow, and have compression heat. Moreover, since the compression is repeated many times in a short time by the reflux structure, the temperature of the airflow blown into the drying chamber 9 instantaneously rises.

As described above, according to the present embodiment, a hand drying device that has a high drying speed, does not spray germs on the hands, and does not stain the surroundings is realized by the action of the high-speed injection, the reflux structure, the high-temperature jet, and the like. Is what you do.

(Embodiment 2) Next, a second embodiment of the present invention will be described. As shown in FIG. 3, in the present embodiment, a sterilizing means 16 is provided in the drying chamber 9. In this embodiment, a germicidal lamp is used as the germicidal means 16. Also, in order to further enhance the effectiveness of the sterilizing means 16,
The inside surface of the drying chamber 9 is covered with a reflecting member 15.

With the above configuration, the hand surface can be sterilized during drying, and a hand drying device capable of cleaning the hand surface can be realized. That is, when the electric blower 4 is dried by the airflow, the sterilizing means 16 is turned on to generate ultraviolet rays. The ultraviolet light is reflected by the reflecting member 15 covering the inner surface of the drying chamber 9.
It can be distributed on the front of the drying chamber 9. Therefore, at the stage where drying is completed, the surface of the hand can be sterilized as described above, and the surface of the hand can be cleaned.

Although a germicidal lamp is used as the germicidal means 16 in this embodiment, for example, a high-temperature heater or an ultrasonic transmitter can be used.

(Embodiment 3) Next, a third embodiment of the present invention will be described. In the present embodiment, as shown in FIG. 4, sterilizing means 17 is provided inside the return passage 12 for returning the suction airflow from the suction hole 11 of the drying chamber 9 to the electric blower 4.
A germicidal lamp is installed. The sterilizing means 17 is turned on at the same time as the drying operation.

With the above configuration, wet hands are dried by clean air. That is, the airflow that has entered the return passage 12 due to the reflux is sterilized by the ultraviolet light generated by the sterilization unit 17. Therefore, when the blown airflow of the electric blower 4 is blown out from the blowout holes 7 and 8, the blower is in a clean state.

At this time, if the lighting of the sterilizing means 17 is continued from during the drying operation until a certain time has elapsed after the end of the drying, it is possible to sterilize various bacteria remaining in the apparatus after the end of the drying. . Therefore, in the case of this configuration, it is possible to prevent a situation in which the germs blown away from the wet hands together with the moisture propagate inside when not in use and generate an odor.

In other words, with this configuration, it is possible to realize a hand-drying device that can dry at high speed with air full of refreshing feeling.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described. In this embodiment, as shown in FIG. 5, a disinfectant case 19 containing a disinfectant, an injection pump 20 for injecting the disinfectant from the disinfectant case 19 into the drying chamber 9, and an injection pump 20 are provided. And a switch 23 to be driven. The disinfectant case 19 is detachable from the main body by opening the lid 18.
When the injection pump 20 operates, the disinfectant contained in the disinfectant case 19 is injected into the drying chamber 9 from the injection hole 22 at the end of the hose 21. The switch 23 is provided near the insertion slot 10 of the main body.

The operation of the embodiment will be described below. The disinfectant case 19 is detachable from the main body by opening the lid 18 as described above. Therefore,
An arbitrary disinfectant can be stored in the disinfectant case 19 and set on the main body. If the amount of the stored disinfectant decreases, it can be added freely. The operation of the switch 23 is left to the user, and the user can freely determine whether or not to use the disinfectant. When the switch 23 is pressed, the injection pump 20 is operated, and the disinfectant in the disinfectant case 19 is injected from the hose 21 into the drying chamber 9. Accordingly, the inside of the drying chamber 9 is filled with the disinfectant, and the inserted wet hand 13
Can be quickly dried, and the surface of the surface can be killed by a disinfectant to cleanse.

At this time, according to the present embodiment, any disinfectant can be used, and in some cases, a cosmetic product such as a hand roughening preventive can be used.

As described above, according to the present embodiment, it is possible to realize a hand drying device which can select whether or not to use a disinfectant and select the type of disinfectant according to the user's preference.
