BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to an air dryer for washing hands and then removing air by blowing air, that is, air attached to hands without using a towel or the like. .

[0002]

2. Description of the Related Art Conventionally, when water is adhered to a hand after washing the hand, air, that is, air is blown to the hand without using a towel or the like, and the water attached to the hand is removed by blowing off the water. In other words, an air-type dryer, which is generally called an air towel or the like, is widely used.

[0003] The air dryer has a configuration as shown in FIGS. 16 and 17. That is, as shown in the figure, the air dryer 100 is provided with a rear drain case 110 and a front drain case 120 above the main body 101 and has an opening 102 for inserting a hand between the two drain cases 110 and 120. The formed gap, that is, the insertion / removal gap 103 into which the hand to be dried is inserted is formed.

A nozzle having a plurality of ejection ports 112a arranged in a line for ejecting air, that is, air, is provided on inner wall surfaces 111 and 121 of the rear draining case 110 and the front draining case 120 on opposite sides. 11
2 and a nozzle 122 having an ejection port 122a, and an air supply device including a blower (not shown) is provided in the main body 100. Air supplied from this air supply device is supplied to the nozzles 112a of the nozzles 112 and 122. , 122a.

[0005] To remove water adhering to the hands when the hands are washed, that is, to dry the hands, the hand with the water adhered is inserted into the insertion gap 103, and the air supplied from the air supply device is supplied. Is ejected from the ejection ports 112a and 122a of the nozzles 112 and 122, and the water attached to the hand is removed by blowing off the water as described above.

The above-described conventional air dryer 100 has the rear draining case 110 and the front draining case 120 fixed to each other, so that the rear draining case 110 and the front draining case 120 are opposed to each other. The size of the opening 102 is always constant, and the opening 102 is preferably not too large from the viewpoint of increasing the water removal efficiency in the insertion gap 103, and is not so large. , This opening 10
When inserting a hand into the insertion gap 103 from 2, it is difficult to reach the hand, and the hand touches the opening edge of the opening 102, which is not always preferable in terms of hygiene.

Further, as described above, the double draining case 110
And 120 are fixed, the opening 102 is always open, and the front draining case 120
Is always protruding toward the front side, that is, the user side, and is an obstacle when not in use.

The drain cases 110 and 120
Nozzles 112 and 122 are fixed to both drainage cases 110 and 120, so that the ejection directions of the ejection ports 112a and 122a are always in a fixed direction, and the position where air is ejected is in a fixed area. Limited to Therefore, when the hands are dried, that is, to remove the adhered water, a troublesome operation of reciprocating the hands in the insertion / removal gap 103 in the insertion / removal direction is required, which is not preferable in terms of usability.

Further, the hand inserted into the opening 102 and the insertion gap 103 is carefully positioned at the opening edge of the opening 102 and substantially at the intermediate position between the nozzles 112 and 122 during use, and this state is maintained. Also, in the state where it is deviated to one side from the intermediate position, the jetting power of the air to the side distant from the nozzle, that is, the wind speed becomes weak, and the water cannot be efficiently removed as a whole. . On the other hand, if it is excessively biased to one side, the hand touches the opening edge of the opening 102 and becomes unsanitary.

[0010]

As described above, in the conventional air dryer, firstly, the rear draining case and the front draining case are fixedly provided. Since the insertion gap formed at the distal end of both drainage cases from the surface is not large, it is difficult to insert a hand when inserting the hand into this insertion gap. There is a problem that it is not always preferable from a hygiene point of view because the hand touches the hand.

Second, since the two drainage cases are fixed as described above, the opening formed at the upper end of the two drainage cases is always open, and the front drainage case is also provided. Is configured to protrude forward ,
There is a problem that it is disturbing when not in use .

Thirdly, since the ejection direction of the nozzle outlet is constant, when removing water, there is a troublesome operation that the user must reciprocate in the direction of putting his hand in and out of the insertion gap. This is necessary and is not preferable in terms of usability.

Fourthly, the hand inserted into the insertion gap formed by the double draining case is carefully positioned at the opening and substantially in the middle of both nozzles during use, and this state is maintained. It is not preferable in terms of usability, and water is not efficiently removed in a state where it is biased to one side from the intermediate position, and if it is too biased to one side, the hand touches the opening edge of the opening It becomes unsanitary.

[0014]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the first problem described above. A draining case on one side and a draining case on the other side, each having a nozzle on the facing surface, are provided so as to face each other, and an insertion gap is provided between these two cases.

This is an air dryer in which the direction of the air outlet is changed by rotating the nozzle to change the direction of the air outlet.

Thus, when an object to be dried is inserted into the drying space, the two draining cases are moved toward and away from each other to change the direction in which air is blown out.
The water that adheres can be removed while keeping the hand to be dried still.

Another object of the present invention is to solve the fourth problem, and one side of the main body is provided so as to oppose each other and has nozzles on opposing surfaces. A draining case and a draining case on the other side are provided, an insertion gap is provided between the two cases, and a cover inserted into the insertion gap by air sent from an air supply device provided in the main body and jetted from the nozzle. In an air dryer for drying a dried product, the one-side draining case and the other-side draining case are rotatably provided while being pivotally supported, and a driving means for rotating the one-side draining case and the other-side draining case is provided. Separation distance detecting means for detecting the separation distance between the one-side drainage case and the object to be dried, which is provided on the opposite surface of the one-side drainage case and the other-side drainage case, and the separation distance Control means for controlling the driving means so that the separation distance between the nozzles and the object to be dried is set to a predetermined distance based on a detection signal of the detection means, and the control means detects the separation distance detection means An air dryer in which the driving unit is controlled based on the result to maintain a separation distance between the object to be dried inserted in the insertion gap and each of the nozzles at a predetermined separation distance. .

In this manner, the distance between the object to be dried and the two nozzles is automatically maintained at a predetermined distance. It is not necessary to hold the nozzle approximately at the middle position, and since the distance between the object to be dried and the two nozzles is maintained at a predetermined distance, water can be efficiently removed. It has an effect of preventing a hand as an object from touching.

As shown in FIG. 6, air jetted from the nozzle 65 provided on the nozzles collides with a plane connecting the axis of the rotating shafts 51a and 51b and the intermediate point between the opposed nozzles 60 and 65. . This effectively removes water adhering to the hand. This is because when the hand is inserted into the insertion gap G described later, since the hand is positioned substantially on the plane, the air ejected from the two nozzles is blown on both sides of the hand with substantially the same strength. This is because water adhering to both surfaces is removed almost simultaneously.

The surface of the rear draining case 26 facing the front draining case 50, that is, the inclined wall 24 of the rear draining case 26 and the bottom wall 52 of the front draining case 50 are disposed opposite to each other.

Then, after washing the hands, the hand with the water remaining attached is inserted into the insertion gap G from the opening H, and the attached water is blown away by the air ejected from the nozzles 60 and 65. And the like, and the attached water is removed without using a towel or the like, that is, it is dried.

The inclined wall 2 of the rear draining case 26
In the vicinity of the opening H, a light emitting element 70a composed of a phototransistor is provided.
The light receiving element 70b, which is a phototransistor that receives light emitted from the light emitting element 70a, is provided near the opening H on the bottom wall 52 of the zero. The light emitting element 70a and the light receiving element 70b constitute detection means for detecting that a hand has been inserted into the insertion gap G through the opening H, that is, whether or not a hand has been inserted into the insertion gap G. It is. When the hand is inserted into the opening H, the light from the light emitting element 70a is blocked by the hand and the light receiving element 70b does not receive light. The signal from the light receiving element at this time is inserted into the insertion gap G by the hand. Control means 3 via a signal line (not shown)
3, when the hand is not inserted, the light from the light emitting element 70a is received by the light receiving element 70b,
At this time, the signal from the light receiving element 70b is sent to the control means 33 via a signal line (not shown) as a signal in which the hand is not inserted into the insertion gap G.

A display panel S is provided on the upper surface of the main body case 20, and the display panel S is provided with display lights 35a to 35f each composed of a plurality of LEDs for displaying each operation state of the dryer.

When water adhering to the hand in the insertion gap G is removed by air, the removed water is collected in the water storage case 2 by water collecting means (not shown) and stored in the water storage case 2. Can be A germicidal lamp L composed of an ultraviolet lamp is provided below the inclined wall 24 of the rear draining case 26 below the nozzle 60.

Next, the operation and control of the dryer 1 configured as described above will be described with reference to a control block diagram shown in FIG. First, when a hand is not inserted into the insertion gap G through the opening H, the light receiving element 70b receives light emitted from the light emitting element 70a, and a signal based on the received light, that is, a hand A signal indicating that it has not been inserted into the insertion gap G is sent to the control means 33.
Based on this signal, the control means 33 controls the drive of the stepping motor 40 so as to rotate the front draining case 50 in a direction away from the rear draining case 26, and a separation distance between the two draining cases 26 and 50, When the insertion gap G is opened to a predetermined size, that is, a predetermined size, the driving is stopped. Therefore, the insertion gap G
When the hand is not inserted in the dryer 1, that is, when the dryer 1 is not used, the front draining case 50 is largely separated from the rear draining case 26, and the opening H and the insertion gap G are large. (The state shown in FIG. 5A). Therefore, when starting to use, the opening H and the insertion gap G are largely open, so that the hand can be easily inserted and the hand does not touch the opening edge of the opening H, so that it is not unsanitary. is there. Control means 3
No. 3 controls the electric blower 46 to a stopped state, so that no air is ejected from the nozzles 60 and 65.

Next, when the hand is inserted into the insertion gap G through the opening H, the light receiving element 70b stops receiving the light emitted from the light emitting element 70a.
Is sent to the control means 33 as a signal indicating that the hand has been inserted into the insertion gap G. The control means 33 controls the drive of the stepping motor 40 based on this signal so that the front draining case 50 approaches the rear draining case 26 and rotates the insertion gap G in a direction to reduce the insertion gap G. Control is performed so as to stop when it becomes smaller and reaches a predetermined size (the state shown in FIG. 5B). The time when the insertion gap G reaches a predetermined size is a size at which water adhering to a hand can be removed most efficiently by air jetted from the nozzles 60 and 65. The gap from which water adhering to the hand can be removed most efficiently varies depending on the size or shape of the dryer and is determined by experiments or the like.

The control means 33 controls the electric blower 46.
Is driven from the nozzles 60 and 65, the water attached to the hand is removed by the air as described above, and the removed water is stored in the water storage case 2. Then, the user removes the hand from the insertion gap G when the water of the hand is removed, that is, puts the hand out. However, when the user removes the hand from the insertion gap G, the light receiving element 70 is removed.
b again receives the light from the light emitting element 70a and sends a signal to the control means 33 that the hand is not in the insertion gap G. Based on this signal, the control means 33 controls the drive of the stepping motor 40 again, rotates the front draining case 50 in a direction away from the rear draining case 26, and when the predetermined separation distance is reached, When the insertion gap G reaches a predetermined size, control is performed to stop driving. In order to prepare for the next use, the hand is inserted into the insertion gap G so as to be easily inserted. The control means 33
Is controlled to stop the electric blower 46 and the nozzle 60
And the ejection of air from 65 stops.

As described above, in the non-use state, the insertion gap G is made large so that the hand to be dried can be easily inserted, and when the insertion of the hand into the insertion gap G is detected. Since the insertion gap G is reduced to a predetermined size, it is easy to insert a hand in use, and it is sanitary without touching the opening edge of the opening H with the hand. When the hand is inserted, the insertion gap G is small, that is, a predetermined size, so that water attached to the hand can be efficiently removed.

In the above embodiment, only the front draining case 50 is rotated to change the size of the insertion gap G of the draining case.
The front draining case 50 and the rear draining case 26 are provided separately from the main body case 20 so as to be rotatable similarly to the front draining case 50, and the front draining case 50 and the rear draining case 26 are rotated by the stepping motor 40 in conjunction with each other. Good thing.

In the above embodiment, the light emitting element 70a
The detecting means is constituted by the light receiving element 70b and the light receiving element 70b. However, the present invention is not limited to this. Any sensor element may be used as long as it can detect that the hand is inserted. .

Next, a second embodiment of the present invention will be described with reference to FIGS. This second embodiment is an embodiment of the invention described in claim 2.

The second embodiment differs from the first embodiment in that the dryer of the first embodiment is provided with a user detecting means and a time measuring means, and the operation of the dryer is not limited. This is a control point, and the other configuration is the same as that of the first embodiment. The same components are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 7, on the front surface 27 of the upper part of the main body case 20, a user detecting means 72 composed of, for example, an infrared sensor or the like is provided. This user sensing means 72
When a user stands in front of the dryer 1, that is, at a use position, the user is sensed and the sensed signal is sent to the control means 33 via a signal line (not shown). Further, the circuit board 31 is provided with a time measuring means including a timer (not shown) as one of the circuit components. When the control means 33 receives the sensing signal from the user sensing means 72, it controls the stepping motor 40 and the electric blower 46 based on the sensing signal, and inserts the light from the light receiving element 70b of the sensing means. The timing of the timing means is started based on a signal indicating that a hand has been inserted into the gap G.

Next, the operation and control of the air dryer 1 according to the second embodiment will be described with reference to the block diagram shown in FIG.

First, when the dryer 1 is not in use, the control means 33 controls the driving of the stepping motor 40, and connects the front draining case 50 to the rear draining case 26.
The drive is stopped when the front end of the front draining case 50 approaches the rear draining case 26 until the front end of the front draining case 50 substantially contacts the rear draining case 26. In this state , the front draining case 50
Is held in a substantially vertical state (the state shown in FIG. 9A), so that it cannot project forward of the main body case 20.
So it doesn't get in the way .

Next, when the user stands in front of the dryer 1, that is, at the use position, the user sensing means 72 senses the user and sends a sensing signal to the control means 33. Control means 33
Drives and controls the stepping motor 40 based on the sensing signal, and connects the front draining case 50 to the rear draining case 2.
6, the opening H and the insertion gap G are enlarged, and the stepping motor 40 is opened when it is opened to a predetermined size, that is, the maximum size as shown in FIG. 9B. Stop. Since the opening H and the insertion gap G are largely opened in this way, the user can easily insert the hand, and can prevent the hand from touching the opening edge of the opening H during insertion.

Next, when the user inserts his hand into the insertion gap G through the opening H, the light receiving element 70b
Light emitted from Oa is no longer received, and at this time, a signal from the light receiving element 70b is sent to the control means 33 as a signal indicating that a hand has been inserted into the insertion gap G. Control means 3
3 controls the drive of the stepping motor 40 based on this signal so as to bring the front draining case 50 closer to the rear draining case 26 and rotate it in a direction to reduce the insertion gap, and as shown in FIG. 9C. In this way, the control is performed so that the insertion gap G is reduced to a predetermined size, that is, when the insertion gap G reaches a size in a use state, and then stopped. The predetermined size of the insertion gap G in the use state is a size capable of removing water adhering to the hand most efficiently by air jetted from the nozzles 60 and 65 as in the case of the first embodiment. This is determined by experiments or the like depending on the size and shape of the individual dryers.

The control means 33 drives and controls the electric blower 46 based on a signal indicating that a hand has been inserted into the insertion gap G from the light receiving element 70b.
Air is blown out from 0 and 65, and water adhering to the hand is removed by the air as described above.

At the same time as driving the electric blower 46, that is, based on a signal indicating that a hand has been inserted into the insertion gap G from the light receiving element 70b, the control means 33 controls the time measuring means to measure the time. When the timer is started, and the timer measures a predetermined time, that is, a time sufficient to remove the water adhering to the hand, the control means 33 controls the stepping motor 4.
0 to drive the front draining case 50 to the rear draining case 26
The opening H and the insertion gap G are again rotated to the maximum size (FIG. 9).
(D). When the timer measures the predetermined time, the electric blower 46 stops under the control of the control unit 33, and the ejection of air from the nozzles 60 and 65 stops.

[0050] Thereafter the user the light receiving element 70b and excluding hand from the insertion gap G receives light from the light emitting element 70 again sends a signal that is not within the insertion gap G hand to the control means 33 . Based on this signal, the control means 33 controls the driving of the stepping motor 40 again to rotate the front draining case 50 in a direction approaching the rear draining case 26, and the front end of the front draining case 50 is rear drained. It is rotated until it returns to the state where it is substantially in contact with the case 26, that is, the first unused position , that is, the state shown in FIG.
Then , control is performed to stop the stepping motor 40. In this state, that is, in the non-use state, as described above, the front end of the front draining case 50 is substantially in contact with the rear draining case 26, so that the front draining case 5
0 does not protrude forward of the main body case 20 so that it does not get in the way when not in use, and can prevent dust or the like from entering inside.

When the user is sensed by the user sensing means 72, the opening H and the insertion gap G are enlarged, so that the hand can be easily inserted, and the hand touches the opening edge of the opening H. Can be prevented.

In this embodiment, the insertion gap G is increased in order to remove the hand from the use state (the state shown in FIG. 9C). Is not always necessary and can be omitted when the value is large to some extent. In this case, the time counting means can be omitted.

As described above, when not in use, the front end of the front draining case 50 is brought close to contact with the rear draining case 26 so as to be substantially in contact with the rear draining case 26. When the user is in the use position, the front draining case 50 is separated from the rear draining case 26 so that the opening H and the insertion gap G of the draining case are maximized.
0 in the direction to approach the rear draining case 26,
The insertion gap G is maintained at a predetermined size, and the electric blower 46 is driven to eject air from the nozzles 60 and 65. Then, when the hand is removed from the insertion gap G, the front draining case 50
The rotated to the extent that its tip contacts the rear draining case 26 substantially in which the state is controlled to be maintained. Therefore, when not in use, the front draining case 50 does not protrude from the main body case 20 and does not interfere, and dust can be prevented from entering the insertion gap G. When a hand is inserted, the opening H and the insertion Since the gap G is wide open, it is easy to insert a hand, it is possible to prevent the hand from touching the edge of the opening H, and it is sanitary. The size is such that water adhering to the hand can be removed, so that water adhering to the hand can be efficiently removed.

In this embodiment, only the front draining case 50 is rotatable. However, the rear draining case 26 is provided separately from the main body case 20 so as to be rotatable in the main body case 20. , 26 may be rotated in conjunction with each other.

Next, a third embodiment of the present invention will be described with reference to FIGS. The first embodiment is different from the first embodiment in that a rear draining case is rotatably provided in a main body case, and a stepping motor as a driving means is moved toward and away from the front draining case in conjunction with the front draining case. And operation and its control are different
Since other configurations are the same as those of the first embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 10, a storage space having a front opening is provided on the upper front side of the main body case 20, and a rear drain case 226 as the other side is provided in this storage space. 227a and 227b (only 227a is shown in the figure)
a and 25b. The rotating shaft 227a has a rotating shaft 51 of the front draining case 50.
A gear 44a that meshes with the gear 44 attached to the gear a and has the same shape as the gear 44 is attached.
By this, when the gear 44 rotates clockwise, the gear 44a rotates counterclockwise, and when the gear 44 rotates counterclockwise, the gear 44a rotates clockwise. Rear drainer case 22
Numerals 6 are linked to each other and rotate in the direction approaching or moving away at the same speed.

By operating the front draining case 50 and the rear draining case 226 so as to approach or separate from each other, the nozzle 65 and the nozzle 60 attached to the two draining cases 50 and 226, that is, the ejection ports 65a and The direction in which the air is ejected from the ejection port 60a changes.

Next, the operation of the dryer 1 of this embodiment will be described with reference to the control block diagram of FIG.

First, when no hand is inserted through the opening H into the insertion gap G, as in the case of the first embodiment, if no hand is inserted into the insertion gap G from the light receiving element 70b. The transmitted signal is sent to the control means 33.
Based on this signal, the control means 33 controls the drive of the stepping motor 40 so that the stepping motor 40 is rotated in a direction away from the front draining case 50 and the rear draining case 226, and the insertion gap G is adjusted to a predetermined size. Control to stop driving when opened. As a result, in a state where no hand is inserted into the insertion gap G, that is, in a state where the dryer 1 is not used, the draining case, that is, the rear draining case 226 and the front draining case 50 are largely separated from each other, and the opening H,
The insertion gap G is large, so that the hand can be easily inserted at the start of use and the hand does not touch the opening edge of the opening H. Further, since the control means 33 controls the electric blower to be in a stopped state, no air is blown from the nozzles 60 and 65.

Next, the hand insertion gap G is inserted through the opening H, a signal indicating that the hand is inserted into the insertion gap G from the light receiving element 70b is sent to the control unit 33. The control means 33 controls the stepping motor 40 based on this signal so as to drive the stepping motor 40 so as to repeat clockwise rotation and counterclockwise rotation repeatedly, and to control the electric blower 4.
6 is driven. Then, the front draining case 50 and the rear draining case 226 operate so as to approach / separate from each other by the repeated clockwise rotation and counterclockwise rotation of the stepping motor 40 repeatedly,
Along with this approaching / separating operation, the jetting direction of the air jetted from the nozzles 65 and 60 attached to the draining cases 50 and 226 sequentially changes from the palm of the hand to the fingertip. Continued repeatedly.
With this change, the air blown to the hand changes from the palm to the fingertip. This allows
Even when the hand inserted into the insertion gap G is stationary, the air ejected from the nozzle 65 and the nozzle 60 is blown while changing sequentially from the palm of the hand to the fingertip, and water adhering to the hand is removed. Removed. Note that the time during which the stepping motor 40 is repeatedly rotated clockwise and counterclockwise is controlled by the control unit 33 using a timer unit, and the insertion gap G is manipulated from the light receiving element 70b. The timing may be started based on a signal indicating that the timing has been measured, and terminated when a predetermined time has been measured.

Then, the hand from which the attached water has been removed is inserted.
When removed from the gap G, the light receiving element 70b receives the light from the light emitting element 70a and sends a signal to the control means 33 that the hand is not in the insertion gap G. Control means 33 based on this signal drives and controls the stepping motor 40, a front draining casing 50 and the rear draining case 226 is rotated in a direction away from each other, largely opened the opening H and insertion gap G Control is performed so that the drive is stopped when the device is in a state, that is, when it is greatly opened as in the case of non-use, so that the hand is easily inserted at the next use. Control means 3
3 controls the electric blower 46 to stop, and controls the nozzle 6
The jetting of air from 0 and 65 is stopped.

It is to be noted that the time is determined not when the hand is removed from the insertion gap G but when the repetition continuation operation of the two drainage cases 50 and 226 is completed, that is, when the time for the repetition continuation of the time counting means is measured. Stepping motor 4
0, the drainage cases 50 and 226 may be separated from each other to enlarge the opening H and the insertion gap G. In such a case, the insertion gap G
There is an advantage that the hand can be easily put out of the opening H and the hand can be prevented from touching the opening edge of the opening H.

As described above, when not in use, that is, when the hand is not inserted into the insertion gap G, the drainage cases 50 and 226 are separated from each other so that the opening H and the insertion gap G are enlarged , and the insertion gap G When the hand is inserted into the case, the operation of moving the two draining cases 50 and 226 toward and away from each other is repeated and continued, so that the hand can be easily inserted into the insertion gap G. H is sanitary because the hand does not touch the opening edge of the nozzle H. Further, even if the hand inserted into the insertion gap G is kept stationary, the nozzle 65
Since the attached hand water is reliably removed by changing the direction of the air blown from the first and the second 60, the troublesome operation of moving the hand in the insertion gap G unlike the conventional one is not required.

In this embodiment, the user detecting means 72 is not used, but the user detecting means 72 is used to close the opening H when not in use as in the second embodiment. Then, when the user is detected, the two drainage cases 50 and 226 may be operated so as to greatly open the opening H and the insertion gap G. In such a case, the second embodiment is performed. In the same manner as in the above embodiment, the installation space when not in use can be reduced, there is no obstruction, and the intrusion of dust from the opening H can be prevented when not in use.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. Also in this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 13, a storage space having an open front side is provided on the upper front side of the main body case 20, and a rear drainage case 32 as the other side drainage case is provided in this storage space.

(Only 327a is shown in the figure)
Are supported by bearings (not shown) provided on both side walls 25a and 25b. And, this rotating shaft 327a
The gear 344 is attached to. Further, a stepping motor 340 different from the stepping motor 40 is mounted on the upper portion of the mounting frame 23, and a small-diameter gear 341 is mounted on a rotation shaft 340a of the stepping motor 340. The gears 342, 343, and 344 are sequentially meshed with each other, and the gear 344 is attached to the rotating shaft 327a. The gears 341 to 344 constitute a speed reduction mechanism, and the speed reduction mechanism and the stepping motor 340 form a drive mechanism. The stepping motor 340 is controlled and driven by the control means 33.

Therefore, the rear draining case 326 is controlled by the stepping motor 340 controlled by the control means 33.
The front draining case 50 is rotated by the stepping motor 40.

An ultrasonic sensor 75a as a separation distance detecting means is attached to the front wall 60b of the casing of the nozzle 60 attached to the rear draining case 326. An ultrasonic sensor 75b as a separation distance detecting means is similarly attached to a front wall 65b of the housing of the provided nozzle 65.
Based on the electric signals from the ultrasonic sensors 75a and 75b, the control means 33 determines the insertion gap G with the ejection port 60a of the nozzle 60 and the ejection port 65a of the nozzle 65.
Is calculated, that is, the distance between the hand inserted into the nozzle, that is, the distance between the nozzles 60 and 65 and the hand, and whether or not the calculated distance is a predetermined distance is determined. If it is not the distance, the distance is adjusted to a predetermined distance. In other words, either the rear draining case 326 or the front draining case 50 is inserted into the insertion gap G with a bias toward one side, or is shifted toward one of the sides while inserted into the insertion gap G, and the nozzles are biased. 60, 6
5 is different from the preset distance, the rear drain case 326 is used.
And the front draining case 50 is rotated so that both nozzles 60
, 65 and the hand are kept at a predetermined distance.

That is, the ultrasonic sensor 75a transmits an ultrasonic wave, receives a reflection of the ultrasonic wave hitting the palm of the hand inserted into the insertion gap G, and measures the time until the transmitted and received ultrasonic wave. The measured time is converted into an electric signal and sent to the control means 33. The control means 33 calculates a separation distance based on the electric signal,
This calculated value, that is, the separation distance is compared with a set value, which is set in advance in the memory means, that is, a predetermined separation distance, and when different from this set value, that is, when the measured separation distance is not within the range of the predetermined separation distance, By driving the stepping motors 40 and 340, the rear draining case 32
6 and the front draining case 50 are rotated to adjust the separation distance to a predetermined separation distance.

Next, the operation of the dryer of this embodiment will be described with reference to the control block diagram of FIG.

First, after the user has washed his / her hand, when this hand is inserted into the insertion gap G through the opening H, the light receiving element 70
b, a signal indicating that the hand has been inserted is sent to the control means 33, and based on this signal, the control means 33
Drive. Then, the air from the electric blower 46 is ejected from the nozzles 60 and 65 to remove water adhering to the hand. When the hand inserted into the insertion gap G is inserted into one of the rear draining case 326 and the front draining case 50 so as to be more than a predetermined range, or within the insertion gap G after being inserted. If it is deviated more than a predetermined range to either side, the hand and both nozzles 60 and 65
Distance between one nozzle or distance is the greater than the predetermined distance, also the distance between the other nozzle is smaller than the predetermined distance. And
The time required for receiving the ultrasonic wave transmitted from the ultrasonic sensors 75a and 75b and reflected on the palm of the hand is measured and sent to the control means 33. Based on the measured value, the control means 33 The separation distance between the nozzles 60 and 65 and the hand is calculated, and this calculated value is compared with the set value set in the memory means. In this case, since the hand is biased to one side beyond a predetermined range , the control means
33 drives the stepping motors 40 and 340 so that the rear drain case 326 and the front drain case 5
0 is rotated so that the distance between the nozzles 60 and 65 and the hand is within the range of a predetermined distance . Also, during this rotation, the separation distance between the hand and the nozzles 60 and 65 is measured by the ultrasonic sensors 75a and 75b, and with the rotation of the rear draining case 326 and the front draining case 50, the nozzle 60 When the distance between the hand and the hand 65 and 65 is within the range of the predetermined distance, the control means 33 controls the stepping motors 40 and 340.
To stop. When the hand moves during use and exceeds a predetermined range, as described above, the ultrasonic sensors 75a and 75
b is the above-described operation, those that will be adjusted to a predetermined distance by the control means 33. Therefore, both nozzles 6
The separation distance between 0 and 65 and the hand is maintained at a predetermined separation distance.

As described above, the ultrasonic sensors 75a, 75
The distance between the nozzles 60 and 65 and the hand is kept at a predetermined distance by the control of the control means 33 based on the electric signal from b. It is not necessary to hold the two nozzles at substantially the intermediate position, and the distance between the hand to be dried and the two nozzles is a predetermined distance, that is, there is no deviation from the intermediate position to one side. It can be removed. In addition, maintaining the separation distance between the hands of the nozzles 60 and 65 and the hand at a predetermined separation distance is equivalent to the case of the double draining case 3.
Since 26 and 50 are located at a predetermined gap from the hand, it is possible to prevent the hand from touching the opening edge of the opening H.

In the above embodiment, the user detecting means is not provided. However, the user detecting means is provided as in the second embodiment, and the user detecting means is provided as in the second embodiment. May be operated.

In the above embodiment, the rear draining case 326 and the front draining case 50 are separately rotated by using the two stepping motors 40 and 340. If formed large,
The insertion gap G may be moved in the same direction as the rear draining case 326 and the front draining case 50 while maintaining this gap. Because the fact that the inserted hand is biased to one side means that it is separated from the other side, if the hand position is at that position, the rear draining case 326 is attached to the biased side. Front draining case 5
This is because the hand can be positioned at an intermediate position of the insertion gap G by rotating 0. In this case, as means for rotating the rear drain case 326 and the front drain case 50 in synchronization in the same direction, for example, the gear 34 provided on the rotation shaft 327a of the rear drain case 326 may be used.
4 and a gear 4 provided on the rotating shaft 51a of the front draining case 50
4 may be configured to mesh with the gear at the last stage of the reduction mechanism. In this case, one ultrasonic sensor can be used.

In each of the above embodiments, the speed reduction mechanism is constituted by a plurality of gears, but this may be constituted by a pulley and a belt.

In the above embodiment, the case where the hand is used as a dried product is shown. However, any other dried product that can be inserted into the insertion gap G can be used for drying the dried product. It is.
