The operation of this embodiment will be described below.
When a wet hand is inserted into the drying chamber 4, the electric blower 1 automatically starts its operation and blows the air inside the chamber. This blast airflow is ejected at high speed from the ejection holes 5 provided in the drying chamber 4 through the path 3. At this time, a large number of ejection holes 5 are arranged around the drying chamber 4, and the airflow ejected from the ejection holes 5 is blown on the hand from all directions. In other words, not only the palm and the back of the hand where the air flow is relatively easy to hit, but also various parts of the hand such as the side surface of the hand, the fingertips, the space between the fingers, and the base of the finger are evenly blown to the airflow. Moreover, since this air flow is inclined in the circumferential direction of the drying chamber 4, a rotating flow is generated inside the drying chamber 4. Therefore, a high-speed airflow is evenly blown to each part of the hand, and as the hand is pulled out from the drying chamber 4, the airflow hits the wrist and fingertips and blows off the adhering water droplets. is there. This water droplet is discharged out of the machine through the drain port 6.

In this embodiment, the ejection holes 5 are circumferentially provided in one row, but it is not particularly limited to one row and may be several rows. Also, the circumferential arrangement may be a spiral arrangement, or may be an irregular arrangement according to the shape of the hand instead of the row arrangement. Further, the total number and the diameter of the ejection holes 5 can be changed as long as the velocity and the total flow rate of the ejected air flow can be maintained. The hole shape is described as a circular shape that is common and easy to process.

Further, in the case of the present embodiment, the inclination angle of the air flow ejected from the ejection holes 5 is relatively small, less than about 30 °, but it is more effective for drying for a short time to hit the hand at an angle close to vertical. . In addition, a rotating flow is easily generated even with a small inclination angle.

Further, although two drying chambers 4 are used for the right hand and the left hand in the present embodiment, there is no problem even if one large room capable of holding both hands is used. Is. Further, although the cross-sectional shape of the drying chamber 4 is circular in this embodiment, it may be rectangular. However, in the case of the rectangular shape, it is difficult to obtain a stable rotating flow, and as a result, the loss of jet energy is large.

Further, at this time, as shown in FIG. 4, the direction of the air flow ejected from the ejection holes 5 is inclined at an angle α both in the circumferential direction of the drying chamber 4 and in the cylindrical axis direction of the drying chamber 4. In this case, the airflow can be given a three-dimensional rotation. That is, the airflow is a vortex that rotates in the circumferential direction and also in the axial direction. Therefore, the water adhering to the surface of the hand flows extremely smoothly from the wrist to the fingertip, and is peeled off from the surface of the hand. Further, the scattered water droplets are sucked in by the flow of the arrow A and are smoothly sent to the drain port 6, and are not scattered to the user side.
