In the hand dryer having this structure, the wet hand is inserted into the hand insertion portion 7, and the hand is inserted into the back and forth upper and lower sensors 34, 35.
When the position is reached, a hand detection signal is sent to the control circuit 30, the DC brushless motor 17 of the high pressure air generator 16 is started, and the turbo fan 18 is rotated. Then, the air sucked from the intake port 15 passes through the second duct 28, passes through the intake side 29, and becomes high pressure in the high-pressure air generation unit 16, and this high-pressure air is discharged from the exhaust side 20 of the high-pressure air generation unit 16 into the first duct.

Upper and lower sensor 32 for transmitting the
33 and inner and upper and lower sensors 34, 35.

Therefore, just by putting a wet hand into the hand insertion portion 7, the air circulates at high speed and the hand is dried in an extremely short time. Further, after drying, the operation of the high pressure air generation unit 16 is automatically stopped by removing the hand from the hand insertion unit 7.
As a result, a quick drying process can be performed easily and easily without any trouble.

In particular, in the hand dryer of this embodiment, since the hand insertion part 7 has a deep part of the space larger than the inlet part, the high-speed air blown out from the blowing nozzle 13 is directed toward the back part of the hand insertion part 7. Flow smoothly. That is, since the pressure of the air blown from the blow nozzle 13 is reduced in the space behind the hand insertion portion 7, the wind speed blown from the blow nozzle 13 is increased. As a result, the drying time of the hands can be shortened. In addition, the high-speed air discharged from the blow-out nozzle 13 has a long distance until it hits the upper surface or the lower surface of the hand insertion portion 7, and the wind speed is reduced accordingly, so that the noise generated at that time is also reduced. Moreover, since the inner part of the hand insertion portion 7 is wide, it is easy to insert the hand, and there is no cramp when inserting.

In the hand dryer of this embodiment, the box 6
The insertion angle of the opening portion of the hand insertion portion 7 that is provided so as to be inserted by opening the front surface 8 and the side surface 9 has an inclination of 0 to 90 degrees with respect to the horizontal axis. Therefore, since the wet hand can be inserted into the hand insertion portion 7 with a natural feeling without a sense of discomfort, the hand can be easily inserted. Moreover, as the inclination angle of the hand insertion portion 7 is increased, the thickness of the front and rear of the hand drying device main body 5 can be reduced, so that the product can be made thinner.

Here, the shape of the hand insertion portion 7 of this embodiment will be further described with reference to the drawings. FIG. 4 is a perspective view showing a frame body of a manual insertion part of a hand dryer according to a first embodiment of the present invention, and FIG. 5 is a cross-sectional view showing a cross section taken along the alternate long and short dash line of the manual insertion part of FIG.

In the figure, reference numeral 44 denotes a frame body of the hand insertion portion 7, which is integrally formed in consideration of cleanability, waterproofness and appearance. The peripheral portion of the manual insertion surface of the frame body 44 is all R-shaped. Reference numeral 44a is a convex portion formed on both side surfaces of the frame body 44 and is higher than the central portion. The frame 44 is also wider at the back than at the entrance.

As described above, in the hand dryer of this embodiment,
A box-shaped body 6 has convex portions 44a at the inner portions of both side surfaces of a hand insertion portion 7 which is opened so that the front surface 8 and the side surface 9 are opened. Therefore, the wind blown out from the blowout nozzle 13 can be prevented from leaking to the outside from both side surfaces of the hand insertion portion 7, and is reliably guided to the intake port 15. As a result, efficient wind circulation can be realized, and the drying time of hands can be shortened. It is also possible to prevent the splashed water droplets from leaking from both side surfaces to the outside.

In the hand dryer of this embodiment, the box 6
A drain reservoir 12 for storing water droplets scattered in the hand insertion portion 7 is located below the hand insertion portion 7 that is provided so that the front surface 8 and the side surface 9 are opened and can be inserted therethrough. Therefore, the water droplets in the hand insertion portion 7 descend due to its own weight and collect in the drain reservoir 12 and do not scatter to the outside of the hand dryer main body 5, so that the water droplets in the hand insertion portion 7 can be easily treated.

Further, in the hand dryer according to the present embodiment, the high pressure air generating portion for sending high pressure air to the blowout nozzle 13 of the hand insertion portion 7 which is provided by opening the front surface 8 and the side surface 9 of the box body 6 is inserted. The intake side 29 of 16 and the intake port 15 formed in the center of the hand insertion portion 7 in the left-right direction are connected by a second duct. That is, as shown in FIG. 2, the intake port 15 is formed substantially at the center of the hand insertion portion 7. Therefore, the intake port 1
Compared with the case where 5 is arranged unevenly, the left-right balance of the air flow flowing in the manual insertion part 7 is good, and the air is less likely to leak from the left and right side surfaces of the manual insertion part 7 to the outside. As a result, efficient ventilation can be realized, and the drying time of hands can be shortened.

In addition to this, in the hand dryer of the present embodiment, the high pressure air is generated by sending the high pressure air to the blowing nozzle 13 of the hand insertion portion 7 which is opened by opening the front face 8 and the side face 9 of the box body 6. The portion 16 is located below the hand insertion portion 7. Therefore, the hand insertion section 7 and the high-pressure air generation section 16 can be efficiently incorporated in the hand drying device main body 5 vertically.
The miniaturization of the hand dryer main body 5 can be promoted. Further, the intake port 15 of the high-pressure air generation unit 16 is provided in the upper rear portion of the hand insertion unit 7, and the intake port 15 and the high-pressure air generation unit 16 are provided.
Since the length of the second duct 28, which is a conduit for the and, can be easily lengthened, the noise generated in the high-pressure air generator 16 can be sufficiently absorbed in the second duct 28 and leaks to the outside from the intake port 15. Noise can be suppressed.

Here, the germicidal lamp 41 arranged in the hand insertion portion 7 of the hand dryer will be described. In the present embodiment, as shown in FIG. 1, the sterilization lamp 41 is provided on the upper surface of the hand insertion portion 7 which is provided so that the front surface 8 and the side surface 9 of the box body 6 are opened.

Therefore, the sterilization light is not directly radiated to the user's eyes, but only the inside of the hand insertion portion 7 is radiated, so that the sterilization light 41 is simply provided, and the safety is higher than that in the case where the sterilization light 41 is provided. You can apply enough UV light. Therefore, the sterilization can be efficiently performed, and the sterilization effect is enhanced. If the sterilizing lamp 41 is disposed deeper than the blowing nozzle 13 in the hand insertion portion 7 as in the present embodiment, the blowing nozzle 13 blocks the user's line of sight and the ultraviolet rays from the sterilizing lamp 41 are Since it does not enter the eyes of the user, it is not absolutely necessary to provide the reflector 42.

Then, ultraviolet rays (sterilizing light) are applied to the inside of the hand insertion portion 7 via the reflection plate 42 located on the front side. As a result, the sterilization light is not emitted to the eyes of the user, and only the inside of the hand insertion portion 7 is emitted, so that the safety is high and the sterilization can be performed efficiently. In this way, if the reflection plate 42 is arranged on the front side,
The disposition position of the sterilization lamp 41 may be appropriately changed. By disposing the sterilizing lamp 41 on the front side of the blowout nozzle 13 as in the present embodiment, the vicinity of the inlet of the hand insertion portion 7 is slightly narrowed, but since the sterilizing lamp 41 can be easily attached and detached, Good workability for maintenance.
