【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described. FIG. 1 is a transparent perspective view of the inside of a hand dryer showing the configuration of the present embodiment. FIG. 2 is a sectional view of the same. The main body 1 includes a hand drying chamber 2 for inserting wet hands, an electric blower 3 for generating high-pressure air, and an ejection hole 4 for blowing out blast air of the electric blower 3 provided near an inlet of the hand drying chamber 2. An intake port 5 provided at the back of the hand drying chamber 2 for collecting the high-speed airflow ejected from the ejection holes 4 and returning the collected air stream to the electric blower 3, and the intake port 5 and the electric blower 3.
An air intake passage 7 communicating with the suction port 6 of the air blower; a ventilation passage 8 communicating with the electric blower 3 and the outlet 4;
b. The sensor 9a is, for example, a light emitting element, and the sensor 9b is a light receiving element that receives infrared rays or the like generated by the light emitting element. The sensors 9a and 9b are provided so as to be embedded in the wall surface of the hand drying chamber 2. The electric blower 3 is constituted by a centrifugal fan, and discharges air taken in from the suction port 6 as high-pressure air. The air inlet 5 is provided in the back of the hand drying chamber 2 on the side opposite to the side on which the electric blower 3 is arranged. The reason for this is that the intake passage 7 serving as a propagation path of the rotation sound of the electric blower 3
Is as long as possible to reduce the rotational noise of the electric blower 3 propagating from the hand drying chamber 2 to the front surface during use. Note that the position of the intake port 5 does not necessarily need to be the extreme end of the main body 1. In this embodiment, a germicidal lamp 10 is provided in the intake passage 7. In this embodiment, an ultraviolet lamp that generates ultraviolet light is used as the germicidal lamp 10. The germicidal lamp 10 is provided in a direction close to the electric blower 2 so as not to be seen from the intake port 5. In other words, the germicidal lamp 10 is placed at a position where it cannot be recognized directly from the hand drying chamber 2 but can be recognized when the germicidal lamp 10 is turned on.

The operation of the embodiment will be described below. When a wet hand is inserted into the hand drying chamber 2, the sensors 9a and 9b provided in the hand drying chamber 2 detect the insertion of the hand, and the electric blower 3 starts operating. The high-pressure air blown by the electric blower 3 is blown into the hand drying chamber 2 as a high-speed airflow from the blowing holes 4 through the blowing passage 8. This high-speed airflow blows away moisture adhering to the hand, and the hand dries in a short time.

At this time, in this embodiment, the sensors 9a and 9
b, the germicidal lamp 10 is turned on at the same time that the electric blower 3 starts rotating. Therefore, the hands during drying are irradiated with ultraviolet rays from the germicidal lamp 10. The lighting of the germicidal lamp 10 is continued until the sensors 9a and 9b no longer detect the presence of the hand. Therefore, at the time when the drying is completed and the user pulls out the hand in the hand drying chamber 2, the bacteria adhering to the hand are sterilized.

As described above, according to this embodiment, the hands can be dried in a short time, and the ultraviolet light from the germicidal lamp 10 can be irradiated to the drying hands, so that the bacteria adhering to the hands can be dried. It can also sterilize the species.

At this time, in the present embodiment, the germicidal lamp 10 is disposed in the intake passage 7 so as not to be directly recognized from the hand drying chamber 2 and to be able to recognize the light when the germicidal lamp 10 is turned on. It is. Therefore, the electric blower 3 is
The ultraviolet light generated by the germicidal lamp 10 is applied to the air blown into the hand drying chamber 2 through the, and various bacteria in the air are sterilized. In addition, naturally, the inside of the apparatus including the inside of the intake passage 7 is also sterilized, so that the entire apparatus can be kept clean. Further, the ultraviolet light emitted by the germicidal lamp 10
Since it does not reach the user's eyes directly, there is no effect on the user's eyes, and the user can recognize indirect light, so that the user can have a sense of cleanliness.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 3 is an operation explanatory diagram for explaining the operation of this embodiment. When the sensors 9a and 9b detect a wet hand inserted into the hand drying chamber 2 at the time point A, the electric blower 3 immediately starts operating at a high speed. At the same time, this signal is transmitted to the germicidal lamp 10, and the germicidal lamp 10 is also turned on. When the user feels the end of drying and pulls his hands out of the hand drying chamber 2, the sensors 9a and 9b detect this at the time point B and switch the operation of the electric blower 3 to low speed. This low-speed operation is continued from time B to time C at which a predetermined time has elapsed. At this time, the germicidal lamp 10 is continuously turned on until the time point C,
It is then turned off. In other words, the germicidal lamp 10 starts detecting the sensor 9 when the electric blower 3 starts high-speed operation.
The air blower 3 is lit continuously until the end of drying is detected by a · 9b and the electric blower 3 ends the low-speed operation for a predetermined time.

Therefore, according to the present embodiment, it is possible to sterilize the bacteria attached to the hand as in the first embodiment, and to surely sterilize the inside of the apparatus after each use. In addition, the sterilization in this device can be performed in a state where the operation sound of the electric blower 3 is set to a low speed, so that the operation sound is low.

At this time, in this embodiment, the stop of the electric blower 3 and the turning off of the germicidal lamp 10 are performed simultaneously at the time point C, but it is not always necessary to set them simultaneously.
