Next, the first air passage 6 and the second air passage 7 shown in FIG. 4 will be described. The air supplied from the first blower 11 and the second blower 12 to the air mixing chamber 10 passes through the first air passage 6 and the second air passage 7, respectively, to the first air blowing nozzles ( 8) Blowing into the drying chamber 2 by the 2nd air blowing nozzle 9 is carried out.

In this embodiment, in FIG. 4, the 1st air passage 6 and the 2nd air passage 7 are arrange | positioned in the front and back of the outer side of the drying chamber 2, and are opposed. Lower ends of the first air passage 6 and the second air passage 7 extend to the lower side of the air mixing chamber 10. The first air passage 6 and the second air passage 7 and the air mixing chamber 10 are connected above the lower ends of the first air passage 6 and the second air passage 7.

Above the 1st air passage 6 and the 2nd air passage 7, the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 are connected, respectively. Therefore, since water may infiltrate from the upper part of the 1st air passage 6 and the 2nd air passage 7, water may invade the 1st air passage 6 and the 2nd air passage 7 by any chance. Water is stored in the lower portion of the first air passage 6 and the second air passage 7. As a result, the water submerged in the first air passage 6 and the second air passage 7 may reach the first blower 11 and the second blower 12 via the air mixing chamber 10. none.

As mentioned above, in this embodiment, the 1st air blowing nozzle 8 and the 2nd air blowing nozzle which were arrange | positioned in the drying chamber 2 which has the hand insertion opening 5 opened toward the exterior, and the opposing surface in the drying chamber 2 ( 9), the 1st blower 11 and the 2nd blower 12 which blow to the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 are provided. The first blower outlet 17 of the first blower 11 and the second blower outlet 18 of the second blower 12 are connected to the air mixing chamber 10. The air mixing chamber 10, the 1st air blowing nozzle 8, and the 2nd air blowing nozzle 9 are connected through the 1st air passage 6 and the 2nd air passage 7, respectively.

Therefore, in this embodiment, when a wet hand is inserted into the drying chamber 2 from the hand insertion port 5, the 1st air blowing nozzle 8 and the 2nd air blowing nozzle which were arrange | positioned on the opposing surface in the drying chamber 2 ( Air is blown out from 9). As a result, the front and back surfaces of the wet hand are curled at the same time, which greatly increases convenience.

In addition, in this embodiment, the air blown out from the 1st blower 11 and the 2nd blower 12 is once mixed in the air mixing chamber 10, and after that, the 1st air path 6 and the 1st It blows into the drying chamber 2 from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 via the 2 air path 7.

For this reason, even if there exists a characteristic deviation in the 1st blower 11 and the 2nd blower 12, for example, the intensity | strength of the blowing air from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 differs. Rarely occurs. As a result, the drying deviation in the front and back of a hand hardly occurs.

In addition, in this embodiment, the 1st blower 11 and the 2nd blower 12 are equipped with the blower which is two, and the 1st blowout port 17 and the 2nd blower 12 of the 1st blower 11 are carried out. It was set as the structure which connects the 2nd blowout outlet 18 of this to the air mixing chamber 10. However, this invention is not limited to the structure provided with two blowers. That is, in addition to the first blower 11 and the second blower 12, an additional blower is further provided, and the above-described effects can be obtained even when the outlets of the plurality of blowers are connected to the air mixing chamber 10. Can be.

Hereinafter, the other characteristic point of the hand drying apparatus of this embodiment is demonstrated.

A plurality of first air blowing nozzles 8 and second air blowing nozzles 9 are respectively arranged on both sides of the drying chamber 2 with the hand insertion port 5 interposed therebetween. This is for reducing the noise by the collision of the air blown out from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 finely.

It is a schematic diagram of blowoff air when air blows off from the air blowing nozzle of the hand drying apparatus of embodiment of this invention. When the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 are arrange | positioned opposingly, the air blown out from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 is shown in FIG. As shown in FIG. That is, since the collision area is limited and the collision area is small, generation of noise due to air collision is reduced.

On the other hand, when the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 are in a non-opposite state, the air blown out from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 is a wide part. Will collide in the air, making the noise louder.

It is a schematic diagram of the blowing air at the time of rocking the air blowing nozzle of the hand drying apparatus of embodiment of this invention to a horizontal direction. When oscillating the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 horizontally, respectively, the oscillation range of the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 is the same. It is also necessary to synchronize the swinging motion.

Next, in this embodiment, as shown in FIG. 1, four optical sensors 14a are respectively provided in the upper part of the 1st air blowing nozzle 8 of the hand insertion hole 5, and the 2nd air blowing nozzle 9, respectively. , 14b, 14c, 14d) are arranged in this order. Hand insertion into the hand insertion port 5 part is detected by some optical sensors 14b and 14c, and hand ejection from the hand insertion port 5 part is the whole optical sensor 14a, 14b, 14c, 14d. ) To the configuration to be detected.

It is a schematic diagram explaining the operation | movement of the hand drying apparatus of embodiment of this invention. As for the optical sensors 14a, 14b, 14c, and 14d, if the 1st air ejection nozzle 8 side is a light emission element, the 2nd air ejection nozzle 9 side will be a light receiving element. Since the hand insertion is detected, usually only the optical sensors 14b and 14c are driven.

When the hand 15 blocks the light of the optical sensors 14b and 14c as shown in FIG. 8 by driving the optical sensors 14b and 14c, the first blower 11 and the second blower 12 are turned off. To drive. At this time, the blowing of the air from the 1st air blowing nozzle 8 and the 2nd air blowing nozzle 9 is started, and drying of the front and back of the hand 15 is started by this.

And when the drive of the 1st blower 11 and the 2nd blower 12 is started in this way, operation | movement of all the optical sensors 14a, 14b, 14c, 14d is started. Then, withdrawal of hand 15 is detected by all optical sensors 14a, 14b, 14c, 14d after that. That is, since the detection of the insertion of the hand 15 is not known when it is performed, the detection of the insertion of the hand 15 is performed more than the optical sensors 14b and 14c only, thereby suppressing the use of electric power.

In addition, the extraction of the hand 15 needs to carry out detection in a wide area. When the hand 15 is moved from side to side, when light is not blocked between the fingers when the hand 15 is pulled out, there is a case where the hand 15 does not exist, which may cause a misjudgement. Therefore, the extraction of the hand 15 is detected by all the optical sensors 14a, 14b, 14c, and 14d.

As described above, the optical sensors 14a, 14b, 14c, and 14d are arranged above the first air blowing nozzle 8 and the second air blowing nozzle 9. When the hand 15 is pulled out of the area | region where blown air collides, the extraction of the hand 15 can be reliably detected by all the optical sensors 14a, 14b, 14c, and 14d. As a result, since the drying operation of the hand drying apparatus can be reliably stopped, useless operation is eliminated and power consumption can be reduced.

The present invention is expected to be widely used as a hand drying apparatus such as a washroom and a toilet.
