Further, the opening edges of the hand insertion portion 4 are all formed into a smooth R shape to improve the touch, and the inner surface of the hand insertion portion 4 is subjected to a water repellent treatment by applying a water repellent paint to prevent the attachment of water droplets. The attachment of dirt is prevented.

The air blowing nozzle 9 on the upper side is downwardly directed to the upper part of the inlet of the hand inserting portion 4, and the air blowing nozzle 9 on the lower side is upwardly directed to the lower part of the inlet of the hand inserting portion 4 so as to form a pressure gradient from the inlet to the back. It is mounted laterally with an inclination to form. Each of the air blowing nozzles 9 is formed with a plurality of nozzle holes in a row in the lateral direction, and the high-pressure air flow sent from the high-pressure air flow generator 2 is supplied from 50 m / s to 15 m / s.
It can be converted into a working air flow with a wind speed of 0 m / s and blown out. An air supply duct 11 is connected to each of the air blowing nozzles 9 in the processing box 1. The other ends of these air supply ducts 11 form a connection port 12 as an air supply port on the back surface or side surface of the processing box 1 and project therefrom.

In addition, as shown in FIG.
As shown in, a sensor 13 for detecting the entry / exit of the hand into / from the hand insertion portion 4 is attached at an interval of about 10 cm to 15 cm. In this embodiment, the sensor 13 is composed of a plurality of infrared light emitting elements such as photo LEDs arranged side by side and a plurality of infrared light receiving elements such as photo transistors arranged side by side, and the light emitting side is on the lower side wall surface. The light-receiving side is attached to the upper side wall surface that is less affected by external light.

As shown in FIG. 3, the high-pressure airflow generator 2 includes a DC brushless motor 14 (which may be an ordinary commutator motor), an electronic circuit 15 for driving the same, and a DC.
Turbofan 1 rotated by brushless motor 14
In this embodiment, two sets are attached in parallel to a frame provided in the main body casing 17. The suction side of the high-pressure air generator 2 is connected to an intake port that opens to the outside.

Each DC on the exhaust side of the high pressure air flow generator 2
Air ducts 18 are provided on the brushless motor 14 side, respectively.
Each end of is connected. The other end of each air duct 18 is connected to the outside of the main body casing 17 as a connection port 1 as an air supply port.

The connection port 19 of the high-pressure air flow generator 2 and the connection port 12 of the processing box 1 are connected to each other by an air pipe 3 that constitutes an external air passage. Further, the sensor 13 of the processing box 1 is connected to the electronic circuit 15 of the high-pressure airflow generator 2, and when the infrared rays of the infrared ray emitting elements on the inlet side and the back side are both blocked and the infrared ray receiving elements are blocked from receiving light, The circuit 15 operates the high-pressure airflow generator 2. Then, when both the infrared rays of the infrared ray emitting elements on the inlet side and the far side are received by the light receiving element, a signal for hand absent detection is formed and the high-pressure airflow generator 2 is stopped.

In the hand dryer as described above, when a wet hand is put into the hand insertion part 4 of the processing box 1, the moisture of the hand is moved by the high-speed working air flow formed in the hand insertion part 4. 4 can be blown away to the back side, and the drying process can be quickly carried out in a visible state where the hand does not feel uneasy. That is, when a wet hand is inserted into the hand insertion portion 4 and the infrared rays of the infrared light emitting elements on the entrance side and the back side are both blocked, and the light reception by the infrared light receiving element is blocked, the electronic circuit 15 causes the high-pressure airflow generator 2 to operate. Each DC brushless motor 14 starts and each turbo fan 16 rotates. Due to the rotation of each turbo fan 16, a high-pressure air flow is sent from each air duct 18 to each air blowing nozzle 9 of the processing box 1 through the air pipe 3, and the air blowing nozzle 9 of the hand insertion portion 4 is inclined at a predetermined angle to the back of the hand. A high-speed working air stream is blown out to both the side and the palm side at the same time.

Further, the processing box 1 is attached to the wall surface 5 of the room, and the high pressure air flow generator 2 is attached to the ceiling 20 as shown in FIG.
It can also be made to function by connecting the two with the air pipe 3 installed along the wall surface 5 along the wall surface 5. As described above, since the processing box 1 and the high-pressure airflow generator 2 can be installed separately from each other, the processing part is simplified, the restrictions on the installation location are reduced, and the usability and usability are increased.

Further, as shown in FIGS. 7 and 8, the processing box 1 is mounted on the upper part of the cabinet 21 which constitutes a sink or a cooking table as one of the kitchen equipment by mounting or embedding, and the inside of the door 22 of the cabinet 21. It is also possible to incorporate the high-pressure airflow generator 2 inside and connect both by an air pipe 3 in the cabinet 21 to form a cabinet type. Even with such a configuration, since the door 22 is closed and used, the driving noise is reduced. The drainage generated in the manual insertion section 4 is convenient because drainage facilities such as a sink can be used. Further, the wash basin other than the kitchen equipment can be similarly configured.
