DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
The embodiment shown in FIGS. 1 to 5 relates to a hand-drying device that dries hands by jetting high-speed airflow. In this hand dryer, as shown in FIG. 1, a high-pressure air flow by a high-pressure air flow generator 2 incorporated in a main body box 1 forming an outer shell having a hand insertion port is sent to the vicinity of the inlet / outlet port 5, A high-speed air flow is formed as a working air flow related to hand drying that blows away moisture into the hand insertion portion 4 constituting the processing chamber 3 that follows the inlet / outlet 5.
[0013]
The hand insertion part 4 can be inserted into and removed from the upper part (see FIG. 1) or the front (see FIG. 3) of the main body box 1 in the vertical direction or the diagonally vertical direction with both hands aligned. It has a deep open container structure with no open drainage channel. The bottom portion of the manual insertion portion 4 is formed in a U shape, and a water container 6 is accommodated therein. The water container 6 is configured as an open container body at the top, and can be inserted and removed from the open side of the hand insertion section 4 or from above.
[0014]
The high-pressure airflow generator 2 includes a DC brushless motor (which may be a normal commutator motor or an induction motor), a drive circuit that drives the DC brushless motor, and a turbo fan or a centrifugal fan that is rotated by the DC brushless motor. In this embodiment, it is attached below or above the manual insertion portion 4 of the main body box 1 and is automatically operated by the control circuit. The intake side of the high-pressure airflow generator 2 faces the intake passage 7 provided in the main body box 1 so that air outside the device can be sucked from the suction port at the end of the intake passage 7. .
[0015]
The outlet of the high-pressure airflow generator 2 is connected to a duct bifurcated into the front side and the rear side of the manual insertion portion 4 in the middle, and is sent from the high-pressure airflow generator 2 to each end of the branched duct. An air nozzle 8 that converts a high-pressure air flow into a high-speed air flow and blows out from the front and the rear in a horizontal line shape is connected to the manual insertion portion 4.
[0016]
The two air nozzles 8 are attached to the front and the rear of the hand insertion portion 4 in the vicinity of the front and rear of the hand insertion portion 4 so as to face each other with the jet port slightly downward, and are placed in the hand insertion portion 4. A high-speed air flow is sprayed onto the hand, and water droplets attached to the hand are peeled off from the surface of the hand without being rubbed together and blown into the hand insertion portion 4.
[0017]
In this hand drying device, when both hands are put into the hand insertion part 4 from the access port 5 to the vicinity of the wrist, the hand is detected by the hand detection sensor for detecting the hand, and the high pressure air flow is processed by the control circuit. The generator 2 is activated, and a line jet, which is a high-speed air stream having high kinetic energy, is blown out from the air nozzle 8 into the hand insertion portion 4 and the moisture adhering to the hand is manually inserted into the front and back of the inserted hand. Blow away to the back of part 4. Further, by inserting and removing the hand in the hand insertion portion 4, all the water adhering to the entire hand is removed, and the hand is dried. When the hand is completely removed from the hand insertion portion 4 after the hand drying process is completed, it is detected that the hand has been removed by the hand detection sensor that detects the hand, and the high-pressure airflow generator 2 stops.
[0018]
The water blown from the hand in the hand insertion part 4 is received in the water container 6 arranged at the bottom. Since the amount of water accumulated in the water container 6 can be visually checked, if water accumulates to some extent, it can be maintained in a sanitary state by removing the water container 6 from the manual insertion portion 4 and mounting it. In many cases, the drainage hose is used to treat the water generated by the drying process of the hand, but the drainage hose is likely to accumulate dirt and easily propagate germs. In addition, the structure such as the drain hose is difficult to clean and is often left in an unsanitary state that emits a foul odor because the dirt cannot be seen. A hygienic state can be maintained only by cleaning the container 6. And the water container 6 is a simple shape, and unlike the drainage hose etc., the cleaning can be performed very simply.
[0019]
As for the way of not using a drain hose or the like for the drainage treatment, a structure corresponding to the water container 6 may be integrally formed at the bottom of the manual insertion portion 4, but the treatment of the accumulated water is removable water. It becomes difficult compared with the case where the container 6 is arranged.
[0020]
The water container 6 may be provided with a funnel-shaped lid 10 having a water passage hole 9 as shown in FIG. By providing the lid 10 on the water container 6, the user can not see the water accumulated in the water container 6, and the usability can be improved.
[0021]
When the high-pressure airflow generator 2 is disposed under the manual insertion portion 4, it is necessary to take measures against water leakage in the manual insertion portion 4 having a drainage channel, but by using the manual insertion portion 4 having no drainage channel. Therefore, it is not necessary to take measures against water leakage, and simplification of the configuration can be promoted. In this way, since measures against water leakage are unnecessary, a degree of freedom is obtained in the arrangement of the manual insertion portion 4 and the high-pressure airflow generator 2, and the manual insertion portion 4 generates sideways and high-pressure airflow as shown in FIG. It is also possible to arrange the device 2. If it is arranged side by side, the height of the device can be reduced, and if it is arranged side by side, the depth of the device can be reduced.
[0022]
Shown to form status by Reference Example 6 and 7, which has taken devised a drainage structure that does not impair the cleaning of the hand insertion portion of the hand dryer shown in the first embodiment is provided to enhance the appearance The configuration other than that is the same as that of the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.
[0023]
In the hand drying device of this reference example , a drain port 11 is provided at the bottom of the hand insertion portion 4. A water container 6 that directly receives the water from the drainage port 11 is disposed below the drainage port 11 in the main body box 1. The high-pressure airflow generator 2 is disposed below, behind or next to the water container 6. The drain port 11 can be easily cleaned with a simple cylindrical structure, and the water is directly introduced into the water container 6 without connecting a drain hose or the like. By adopting this configuration, it becomes a hand-drying device that is hygienic and has good appearance with no visible sewage. Other functions are the same as those of the first embodiment.
