Abstract

PROBLEM TO BE SOLVED: To prevent water drops spattered from hands from being splashed outside by making circulating constitution of spraying an air stream blown by motor driven blower to a drying chamber at high speed and returning it to the blower from the drying chamber. SOLUTION: At the time of inserting wet hands 12 into the drying chamber, a sensor operates to make the motor driven blower 5 start blowing. The air stream blown by the blower 5 is blown out at high speed from an jetting nozzle 8 through a blowing route and this fast jet collides with the surface of the wet hands 12 to tear off water drops to dry the hands 12 in a short time. Then the fast jet tearing off the water drops from the hands 12 is circulated to the blower 5 from a returning passage through the exit of the drying chamber 9. The water drops blown off from the hand 12 is not plashed to the front surface of the chamber 6 as the air stream flows toward the exit 9 provided in the depth of the chamber 6 but the water drops evaporated in a short time by a heating panel provided at a position opposed to the exit 9 of the passage 10.

【Example】

(Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially transparent perspective view showing the configuration of the hand drying device of the present embodiment. The housing 13 is provided with the electric blower 5 and the drying chamber 6 into which the wet hand 12 having the front surface as the opening 7 is inserted. In the vicinity of the opening 7 of the drying chamber 6, there is provided a jet nozzle 8 for blowing the airflow blown by the electric blower 5 into the drying chamber 6 at a high speed. That is, a blowing path is provided between the electric blower 5 and the ejection nozzle 8. At the back of the drying chamber 6, there is provided a drying chamber outlet 9 that functions as an outlet for the airflow jetted from the jet nozzle 8. The drying chamber outlet 9 is provided at a position farthest from the electric blower 5. The drying chamber outlet 9 is connected to a return passage 10 that guides the airflow from the drying chamber 9 to the electric blower 5. The return passage 10 has the longest setting because the position of the drying chamber outlet 9 is located at a position farthest from the electric blower 5. The drying chamber 6 has a substantially closed space in which only the front surface is an opening 8 into which the wet hand 12 is inserted.

The operation of this embodiment will be described below. When the wet hand 12 is inserted into the drying chamber 6, a sensor (not shown) operates and the electric blower 5 starts blowing air. The airflow blown by the electric blower 5 is blown at a high speed from the ejection nozzle 8 through a blowing path. Therefore, the high-speed jet collides with the surface of the wet hand 12 inserted from the opening 7 on the front surface of the drying chamber 6. The water droplets of the wet hand 12 are peeled off by the high-speed jet, and the wet hand 12 dries in a short time. The high-speed jet that has peeled off the water droplets from the wet hand 12 passes through the drying chamber outlet 9 and returns to the electric blower 5 from the return passage 10. That is, the electric blower 5 recirculates the air sucked from the opening 7. When the user pulls out the hand 12 from the drying chamber 6, the sensor detects this and the electric blower 5 stops blowing.

At this time, the water droplets blown off from the wet hand 12 are supplied to the drying chamber 6 in which the drying chamber 6 has a substantially closed space, and the air flow jetted from the jet nozzle 8 is provided at the back of the drying chamber 6. Since it goes to the exit 9, it does not fly to the front of the drying chamber 6.

The water droplets adhere to the inner wall of the drying chamber 6 and adhere to the inside of the return passage 10. Water droplets adhering to the inner wall of the drying chamber 6 evaporate in a short time by the high-speed jet from the jet nozzle 8. Further, the water droplets adhering to the inside of the return passage 10 evaporate similarly because the contact of the airflow returning to the electric blower 5 and the heat generated by the electric blower 5 act as a processing means for evaporating the water droplets.

As described above, according to the present embodiment, the drying chamber 6
Is a substantially closed space, and the blower flow of the electric blower 5 is configured to recirculate between the drying chamber 6 and the electric blower 5, thereby realizing a hand drying device that does not scatter the water droplets separated from the hand to the outside. .

Second Embodiment Next, a second embodiment of the present invention will be described. FIG. 2 is a sectional view showing the configuration of the present embodiment. In this embodiment, the heating plate 1 is provided in the return passage 10.
3 is provided. The heating plate 13 has a configuration in which a heater is provided on a substrate, and is provided at a position facing the drying chamber outlet 9.

The operation of this embodiment will be described below. As described in the first embodiment, the water droplet peeled off from the hand 12 adheres to the inside of the drying chamber 6 or accumulates in the return passage 10 due to the high-speed airflow ejected from the ejection nozzle 8. The water droplets adhering to the inside of the drying chamber 6 are frequently exposed to a high-speed airflow, and evaporate in a very short time. In the present embodiment, the heating plate 13 is provided at a position facing the drying chamber outlet 9 of the return passage 10. Therefore, when the heating plate 13 is energized, water droplets accumulated in the return passage 10 evaporate in a short time. Of course, most of the water droplets accumulated in the return passage 10 are located at a position facing the drying chamber outlet 9, that is, a position where the heating plate 13 is disposed.

As described above, according to the present embodiment, the water droplets are collected by a simple configuration in which the water droplets do not scatter outside and the heating plate 13 is provided at a position facing the drying chamber outlet 9 of the return passage 10. Thus, it is possible to realize a miniaturized hand drying device which does not require a configuration for performing the treatment.

(Embodiment 3) Next, a third embodiment of the present invention will be described. FIG. 3 is a sectional view showing the configuration of the present embodiment. In this embodiment, the heating plate described in the second embodiment is
As shown in the figure, the cooling fan is provided on the entire surface from the drying chamber outlet 9 of the return passage 10 to the air inlet 11 of the electric blower.

With the above configuration, the treatment of water droplets in the return passage 10 can be performed more reliably.

[0018]

According to the first aspect of the present invention, there is provided a drying chamber having a substantially closed space having an opening for inserting a hand, an ejection nozzle for ejecting a jet provided near the opening, and an airflow for the ejection nozzle. As a configuration including an electric blower that blows air, a drying chamber outlet provided on the rear surface of the drying chamber that discharges the airflow flowing through the drying chamber, and a return passage that connects the drying chamber outlet and the electric blower, the air blower was separated from the hand. The present invention realizes a hand drying device that can treat water droplets in a drying room and does not scatter it around.

According to the second aspect of the present invention, the return passage has a heat generating plate, and water droplets accumulated in the return passage can be evaporated by heating by the heat generating plate, so that a special device for collecting and processing the water droplet is not required. In addition, the present invention realizes a hand-drying device that does not sprinkle water droplets around.

According to a third aspect of the present invention, since the heat generating plate is provided on the entire surface of the return passage, it is possible to reliably process water droplets in the return passage and to eliminate the need for a special device for collecting and processing water droplets. The present invention realizes a hand-drying device that does not disperse water droplets around.
