Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air towel device, and more particularly to an air recirculation device for a circulating air towel in which blown air circulates.

[0002]

2. Description of the Related Art As a known recirculating air towel device, there is, for example, one shown in FIG. This known recirculating air towel device 1 generally includes a fan 2 for sending out hot air and a fan 2 that faces downward.
The air outlet 3 is attached to the tip of the air outlet and blows out the warm air sent from the fan 2, and the water when hand-washed by the warm air blown from the air outlet 3 below the air outlet 3 is attached. A drying unit 5 for blowing moisture away from the wet hand 4 to insert the wet hand and an air blown from the fan 2 at a position vertically below the air outlet 3 Air recovery port 6 for recovering moisture blown from wet hands together
A water receiving portion 7 for containing only moisture from the air collected from the air collecting port 6, and an air collected by the fan 2 through the back of the drying section 5 for collecting the air collected from the air collecting port 6. And an air passage 9 for supplying the air to the suction port 8.

As described above, in the known air towel device 1, an air recovery port 6 is provided vertically below the air outlet 3, and the air recovery port 6 blows out the air sent from the fan 2 and wet hands. The collected water is collected together, and thereafter, the collected air flow separates the water and the air, the water is stored in the water receiver 7, and the air is supplied to the air of the fan 2 through the air passage 9. The structure was such that it was fed to the inlet 8.

[0004]

Due to such a configuration, in the conventional apparatus 1, a large amount of water is contained in the air recovered through the air recovery port 6. When the fan 2 is continuously operated, the separation of the air and the moisture from the air collected from the air collecting port 6 cannot catch up, and therefore, the air containing a large amount of the moisture passes through the air passage 9. The air was supplied to the air inlet 8 of the fan 2. As a result, there is a problem that the fan 2 is easily damaged.

In use, the wet hand 4 is used for the air outlet 3
And the air recovery port 6. For this reason,
The air sent from the air outlet 3 hits the wet hand 4, and as a result, the air containing a large amount of water is removed from the air collection port 6.
There is a problem in that it cannot be collected smoothly, and scatters to the back and side surfaces of the drying unit 5 and further to the front part of the device 1 to contaminate the periphery.

Further, since the air to be circulated is once recovered to the water receiving portion 7 having a large volume through the air recovery port 6, it is not possible to improve the wind speed of the blown air by the recirculation. 2 generates a loud noise and consumes a large amount of power.

[0007]

Means for Solving the Problems A fan 12 for sending out circulating air, an air outlet 14 attached to the tip of the fan 2, and a hand 16 which blows off moisture from a wet hand 16 below the air outlet 14 To dry the wet hands 16
Drying section 18 for inserting the air outlet 14
An air recovery port 20 provided on the back of the drying unit 18 for recovering the air sent from the air outlet, and the air recovery port 20 is separately blown away from a wet hand at a vertically lower position of the air outlet 14. A water receiving portion 22 for collecting only the collected water, and an air passage 26 for supplying the air collected from the air collecting port 20 to the air suction port 24 of the fan 12 through the rear of the drying section 18. This is an air recirculation device for a circulating air towel comprising:

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The circulation air towel recirculation device 10 shown in FIG. 1 is preferably provided with a heater or the like (not shown) for sending out hot air, and a fan 12 attached to the tip of the downwardly directed fan 12 and sent out from the fan 12. An air outlet 14 for blowing out hot air,
The wet hand 16 is inserted under the air outlet 14 to blow off moisture from the wet hand 16 and to dry the hand by the warm air blown out from the air outlet 14 and to which the water is applied when hand-washed. A drying section 18 for collecting the air sent from the air outlet 14, an air recovery port 20 provided at the back of the drying section 18, A water receiving portion 22 for recovering only water that is at a vertically lower position and that has been blown away from hands wet by air sent from the fan 12.
And the air collected from the air collection port 20 is dried by the drying unit 18.
And an air passage 26 for supplying the air to the air suction port 24 of the fan 12 through the rear of the fan 12. The fan 12 is activated only when the hand 16 is inserted into the drying unit 18 by a sensing device (not shown) which is known per se. Further, the fan 12 can supply air at normal temperature without a heater or the like.

In the present invention, an air recovery port 20 for recovering the air sent from the air outlet 14 is provided on the back (rear side) of the drying section 18.
Is directly connected to the fan 12 from the air suction port 24 via the air passage 26. Therefore, during operation, the fan 1
The high-speed air sent straight downward from the air outlet 2 through the air outlet 14 first hits directly on the palm or back of the hand 16 wet with water. Therefore, the moisture blown off from the hand 16 wet by the high-speed air is sent to the lower water receiving portion 22 as it is. On the other hand, the high-speed airflow hitting the palm or the back of the hand changes the flow direction from the downward direction to the back (rear side) of the drying unit 18, that is, the rear (the direction indicated by the arrow 28 in FIG. 1). . Therefore, the high-speed air flow is quickly introduced into the air recovery port 20. The air collection port 20
The high-speed air introduced into the fan 12 is directly sent into the fan 12 through the air suction port 24 through the air passage 26. Therefore, the further accelerated high-speed air is blown out from the fan 12 through the air outlet 14. The high-speed air leaked from the palm or the back of the hand is sent to the water receiving portion 22 as it is without changing its direction, where the flow is changed and sent to the air recovery port 20.

As described above, in the present apparatus, the moisture blown off by the high-speed air flow and the high-speed air flow to be recovered are separated in the drying section 18 in advance. Therefore, the air collected into the air collection port 20 hardly contains moisture. Therefore, it has been found that the accident that the fan 12 is broken down by the circulating air sucked from the air suction port 24 hardly occurs.

Further, the water blown off from the wet hand 16 is smoothly stored in the water receiving portion 22 as it is, so that the water is scattered to the peripheral portion of the drying portion 18 and further to the front portion of the device 10, and It won't get dirty.

FIG. 2 discloses another embodiment of the present apparatus. This embodiment is different from the embodiment shown in FIG. 1 in that a filter 30 is attached to the air collecting port 20a in the previous embodiment. The filter 30 prevents moisture from entering the air passage 26a and prevents invasion of various bacteria into the air passage 26a. It is. Other configurations are the same as those of the embodiment shown in FIG.

[0013]

In the present apparatus, the moisture blown off by the high-speed air flow and the high-speed air flow to be recovered are completely separated in advance in the drying sections 18, 18a. Further, the air collection ports 20, 2
0a and the water receiving portions 22, 22a are separately provided. Therefore, the air collected into the air collection ports 20 and 20a hardly contains moisture. Therefore, the circulating air sucked from the air suction port 24 causes the fan 12
It was found that there was almost no accident that 12a caused a failure.

Further, in use, the hand 16 wet with water is located below the air outlets 14 and 14a and slightly inclined downward as shown in the figure. Therefore, the air blown out from the air outlets 14 and 14a is forcibly deflected in the direction indicated by the arrow 28. On the other hand, the water falls directly into the lower water receiving portions 22 and 22a. Therefore, the water does not scatter to the periphery of the drying unit 18 and contaminate the periphery.

Further, the air to be circulated is supplied to the air recovery port 20,
20a and passages 26, 26a, and further, an air inlet 24,
Since the air is quickly collected by the fans 12 and 12a via the air 24a, it is possible to improve the wind speed of the blown air due to the recirculation. Therefore, during operation, the fans 12, 12a operate extremely quietly and do not generate loud noise.
Therefore, power consumption is small.
