Description

  The present invention relates to a cleaning / drying apparatus and a cleaning / drying method for performing at least one of a cleaning process and a drying process on an object to be processed contained in a basket.

Conventionally, a cleaning device that uses a vibrator such as a vibration motor (vibration motor) to vibrate a basket for storing an object to be cleaned (processed object), thereby promoting a cleaning action or a draining action of cleaning liquid. It has been known.
For example, the cleaning device disclosed in Patent Document 1 includes a vibration mechanism that applies vibrations in all directions to a diaphragm by arranging two vibration motors so that their rotation axes are orthogonal to each other.

Japanese Patent No. 2835494

  However, in a vibration mechanism that applies omnidirectional vibration as in the cleaning device of Patent Document 1, when a large number of objects to be cleaned are accommodated in the basket and the objects to be cleaned overlap each other, the object to be cleaned that is above the upper part It is difficult for the object to move upside down and the object to be cleaned located in the lower part moves upside down, so that there is room for further promotion of the cleaning action and the draining action.

  The present invention has been made paying attention to the above-mentioned problems, and facilitates the upside down action of the object to be treated for at least one of the washing process and the drying process, and the washing action (including draining action) and the drying action. It is an object of the present invention to provide a cleaning / drying apparatus and a cleaning / drying method capable of further promoting the above.

For this reason, the cleaning / drying apparatus according to the present invention moves the workpiece in the basket in a constant circumferential direction around the central axis of the basket while jumping the object to be processed in the basket during at least one of the cleaning process and the drying process. A vibration mechanism for applying a circular movement vibration to the basket is provided.
In such a configuration, when the basket is vibrated by the vibration mechanism during at least one of the cleaning process and the drying process, the object to be processed in the basket circulates around the central axis of the basket while jumping. The part where the processed objects overlap is loosened.

Here, the vibration mechanism can include a pair of vibrators arranged opposite to each other with the central axis of the basket interposed therebetween, and each of the pair of vibrators can apply the circular movement vibration to the basket.
In such a configuration, the circular movement vibration is applied to the basket on both sides of the central axis of the basket, and the continuous circular movement of the workpiece can be performed.

Further, the vibrator is a vibration motor that generates centrifugal vibration, and the rotation shafts of a pair of vibration motors arranged opposite to each other with the central axis of the basket interposed therebetween are parallel to the plane passing through the vertical axis and are horizontal. In addition to inclining with respect to the direction axis, the rotation shaft of one vibration motor can be inclined in the opposite direction to the rotation shaft of the other vibration motor.
In such a configuration, each of the pair of vibration motors can generate vibrations that move the object to be processed in the same circumferential direction.

A vibration mechanism having a fixed shaft with the axial direction fixed as a vertical direction; and a vibrating body supported by the fixed shaft so as to vibrate in an axial direction and a rotation direction of the fixed shaft and having a basket suspended at a lower end. , And the pair of vibrators can be fixed to both side surfaces of the vibrating body sandwiching the fixed shaft.
In such a configuration, since the vibrating body is supported so as to be able to vibrate in the axial direction and the rotational direction of the fixed shaft with respect to the fixed shaft, the vibrating body vibrates so as to rotate around the fixed axis while moving in the vertical direction. By applying such vibration to the basket, it is possible to move the object to be processed in the basket in a certain rounding direction around the central axis of the basket while jumping.

Here, the vibration mechanism has a first elastic body that is elastically deformed in response to vibration in the axial direction of the fixed shaft of the vibration body, and a second elasticity that is elastically deformed in response to vibration in the rotational direction of the fixed shaft of the vibration body. And a body.
In such a configuration, the vibration in the axial direction of the fixed shaft is buffered by the first elastic body, and the vibration in the rotation direction of the fixed shaft is buffered by the second elastic body.

In addition, the vibration mechanism may include a structure that makes an attachment angle of the vibrator with respect to the vibrating body variable.
In such a configuration, by changing the attachment angle of the vibrator with respect to the vibrating body, the vibration direction applied to the basket is changed, thereby moving the workpiece to be vibrated up and down, and the workpiece to be moved in the circumferential direction. Power changes relatively.

On the other hand, in the cleaning / drying method according to the present invention, during at least one of the cleaning process and the drying process, a vibration that moves the object in the basket in a constant rotation direction around the central axis of the basket while jumping off the object to be processed in the basket. I gave it to the basket.
In such a configuration, during the at least one of the cleaning process and the drying process, the object to be processed is washed or dried in a state of moving around the central axis of the basket while jumping due to vibration. Processing is performed.
The cleaning process includes a process of immersing an object to be processed (object to be cleaned) in a processing liquid such as a cleaning liquid or a rinsing liquid (in a narrow sense, a cleaning process and a rinsing process). The state drawn from the cleaning liquid or the rinse liquid is also included during the execution of the cleaning process, and vibration can be applied in a state where the object to be processed is drawn from the processing liquid.

According to the cleaning / drying apparatus and the cleaning / drying method according to the present invention, the object to be processed in the basket is moved up and down in a fixed direction around the central axis of the basket while jumping up and down. Is likely to occur.
As a result, the cleaning action (including draining action) and the drying action are promoted, so that the cleaning time and drying time can be shortened to reduce the energy cost, and the draining action of the treatment liquid is promoted. The amount of processing liquid such as rinsing liquid brought into the next process can be reduced.For example, in a cleaning / drying apparatus that performs a series of cleaning, rinsing, and drying processes, the consumption of the cleaning liquid and contamination of the rinsing liquid are suppressed. The rinsing liquid can be used economically, and the drying time can be shortened to reduce the energy cost.

A flange 301 is integrally formed at one end of the fixed shaft 300, and a plurality of through holes (not shown) through which the fixing bolts are inserted are formed on the flange 301 on the same circumference. On the other hand, a through hole (not shown) corresponding to the arrangement and diameter of the through hole of the flange 301 is formed in the approximate center of the upper plate 200.
Then, by fastening the nut to the bolt inserted through the through hole of the flange 301 and the through hole of the upper plate 200, the fixed shaft 300 can be suspended from the lower surface of the upper plate 200 with the axial direction as a substantially vertical direction. Fixed.

Further, a male screw 303 for fixing the mounting base 400 is erected on the lower end surface of the fixed shaft 300, and the male screw 303 inserted through a through hole (not shown) provided in the approximate center of the mounting base 400. By tightening the nut 304, the mounting base 400 is fixed to the lower end of the fixed shaft 300. That is, the upper plate 200, the fixed shaft 300, and the mounting base 400 are assembled together.
On the other hand, the vibrating body 500 includes a box-shaped main body 510, a bearing portion 530 for allowing the fixed shaft 300 to pass therethrough, and a vibration plate 550 that fixes the vibrator 600 and holds the basket 700 in a detachable manner.

The bearing portion 530 penetrates the fixed shaft 300 along an axis passing through the center of the upper surface 511 and the center of the lower surface 512 of the main body 510, and includes a pair of upper and lower bearing portions 531 and 532 to which the fixed shaft 300 is closely fitted. Is done.
Each of the bearing portions 531 and 532 is a cylindrical member having a flange at one end, and the upper bearing portion 531 is configured such that the cylindrical portion is inserted into a mounting hole formed in the upper surface 511 of the main body 510 and the flange portion at the end portion. Is fixed to the upper surface 511 of the main body 510 by screws. Similarly, the lower bearing portion 532 is fixed by inserting a cylindrical portion into an attachment hole formed in the lower surface 512 of the main body 510 and screwing an end flange to the lower surface 512 of the main body 510. The bearing portions 531 and 532 are arranged on the same axis, that is, on an axis passing through the center of the upper surface 511 and the center of the lower surface 512 of the main body 510.

Then, the lower end of the fixed shaft 300 is inserted from the upper bearing portion 531, the fixed shaft 300 penetrates the main body 510, and the mounting base 400 is attached to the lower end of the fixed shaft 300 protruding outside from the lower bearing portion 532. To fix.
In a state where the fixed shaft 300 is inserted through the pair of upper and lower bearing portions 531 and 532, the vibrating body 500 can move up and down (vertical direction) along the axial direction of the fixed shaft 300, and the fixed shaft 300. It is possible to rotate around.

The diaphragm 550 includes a pair of diaphragms 550 a and 550 b fixed to the left and right side surfaces of the main body 510, and the diaphragms 550 a and 550 b face each other in parallel with being attached to the main body 510.
Vibrator 600a is fixed above the end surface of diaphragm 550a, and vibrator 600b is fixed above the end surface of diaphragm 550b. That is, vibrators 600a and 600b are fixed to both sides of the vibrating body 500 sandwiching the fixed shaft 300, and the basket 700 is vibrated using the pair of vibrators 600a and 600b as vibration sources.

A pair of hooks 551 for locking the basket 700 are provided at the lower ends of the diaphragms 550a and 550b, spaced apart in the width direction of the diaphragms 550a and 550b. The basket 700 is suspended below the vibrating body 500 by the four hooks 551.
The hook 551 is extended downward along the end surface of the diaphragm 550, then bent and extended in a direction away from the main body 510, and further bent upward to be substantially J-shaped. The handle portion 701 of the basket 700 is hooked and supported on the tip portion 551a that is formed and extends upward.

The front end portion 551a of the hook 551 is formed in a plate shape substantially parallel to the end face of the diaphragm 550, and a V-shaped cut for positioning the handle portion 701 of the basket 700 in the front-rear direction at the center of the front end edge. A notch 551b is formed (see FIG. 5).
Further, the handle 701 of the basket 700 hooked on the hook 551 is prevented from being separated from the hook 551 due to vibration, and the fixing mechanism 552 for vibrating the basket 700 integrally with the vibration plates 550a and 550b is vibrated. It is attached to the plates 550a and 550b.

The fixing mechanism 552 is a mechanism that fixes the handle portion 701 of the basket 700 in a vertical direction between the hook 551 and is supported so as to be movable in the vertical direction above the hook 551, and the handle portion 701 is hooked to the hook 551. And a actuator 552b such as an air cylinder that generates a force for pressing the pressing portion 552a toward the hook 551, in other words, a force for pressing the pressing portion 552a downward.
In the non-operating state of the actuator 552b, the pressing portion 552a is retracted to the initial position (position shown in FIG. 1) at the upper end of the moving range by the biasing means such as a spring, and the basket 700 can be removed (replaced).

  On the other hand, in the operating state of the actuator 552b, a force that pushes down the pressing portion 552a against the biasing force of the spring is generated, the pressing portion 552a is lowered toward the hook 551, and the pressing portion 552a is the handle portion 701 of the basket 700. The pressing portion 552a presses the handle portion 701 toward the hook 551, and the handle portion 701 is sandwiched between the hook 551 and the pressing portion 552a, whereby the vibrating body 500 (diaphragms 550a and 550b) and the basket 700 are pressed. And the vibration of the vibrator 600 is transmitted to the basket 700 through the vibrating body 500.

The handle portion 701 of the basket 700 is formed by bending a plate-like member into a mountain shape, and is attached so that the ridge line direction of the mountain shape is the front-rear direction of the vibrating body 500. A groove 552c having a cross-sectional cross section is formed on the lower surface of the pressing portion 552a in accordance with the upper shape of the handle portion 701. When the pressing portion 552a presses the handle portion 701, the handle portion 701 presses the pressing portion. The pressing is performed in a state of being fitted in the groove 552c of 552a.
Further, a positioning plate member 701a is attached to the center of the lower surface of the handle portion 701 in the width direction so as to cross the mountain-shaped recess.

When the handle portion 701 of the basket 700 is hooked on the hook 551, the tip of the plate-like member 701a abuts against the inclined surface of the notch 551b of the hook 551, so that the plate-like member 701a is positioned at the valley portion of the notch 551b. The position of the basket 700 in the front-rear direction is corrected.
Further, when the handle portion 701 of the basket 700 is hooked on the hook 551, the tip portion 551 a of the hook 551 hits the inclined surface on the lower side of the handle portion 701, so that the tip portion 551 a of the hook 551 is below the handle portion 701. The position of the basket 700 in the left-right direction is corrected.

On the other hand, as the vibrators 600a and 600b, vibration motors (vibration motors) are used in the present embodiment. The vibration motor is a rotary vibrator that generates centrifugal vibration by attaching an eccentric weight to a rotation shaft (output shaft) of the motor.
Instead of a vibration motor (vibration motor), an air drive that generates centrifugal force vibration by rotating the ball with the force of compressed air or rotating the turbine with an eccentric weight with the force of compressed air These rotary vibrators can be used.

Here, the rotation shafts (rotation center axes) of vibrators (vibration motors) 600a and 600b are provided parallel to a plane passing through the vertical axis and inclined with respect to the horizontal axis. The vibration plates 550a and 550b, in other words, are fixed to both side surfaces sandwiching the fixed shaft 300 of the vibrating body 500 so that the rotation shaft of one vibrator 600a is inclined in the opposite direction to the rotation shaft of the other vibrator 600b. The
More specifically, vibrator (vibration motor) 600a fixed to the left side surface of vibrating body 500 has a rotation axis (rotation central axis) substantially parallel to diaphragm 550a and vibration. The body 500 is fixed so as to have an inclination angle descending toward the back side (rear side) of the body 500. On the other hand, vibrator (vibration motor) 600b fixed to the right side surface of vibrating body 500 has a rotation axis (center axis of rotation) that is substantially parallel to diaphragm 550b and in front of vibrating body 500. It is fixed so as to have an inclination angle that descends toward the side (front side).

  That is, as shown in FIG. 6, the rotation axis AR1 (rotation center axis) of the vibrator (vibration motor) 600a and the rotation axis AR2 (rotation center axis) of the vibrator (vibration motor) 600b are projected in the vertical direction. Are parallel to each other, and on the projection surface in the left-right direction of the vibrating body 500, the rotation axis AR1 (rotation center axis) of the vibrator (vibration motor) 600a and the rotation axis AR2 (rotation) of the vibrator (vibration motor) 600b The rotation directions of the rotation axes AR1 and AR2 are set so that the X axis intersects with the central axis of the rotation axis AR1 and AR2.

In other words, the rotational axes of the vibrator (vibration motor) 600a and the vibrator (vibration motor) 600b are horizontally lowered so as to fall (or rise) in the same circumferential direction around the central axis of the vibrator 500 (basket 700). Inclined from the axis.
Specifically, in the vibration mechanism 100 of the embodiment, the rotation of the vibrator (vibration motor) 600a and the vibrator (vibration motor) 600b in the counterclockwise rotation direction when the vibrating body 500 (basket 700) is viewed from above. The shafts are both inclined upward, and in the clockwise direction, the vibrators (vibration motors) 600a and 600b are vibrated so that the rotation axes of the vibrator (vibration motor) 600a and the vibrator (vibration motor) 600b are both inclined downward. The inclination direction of the rotation axis is set.
In addition, the inclination angle from the horizontal axis | shaft of the rotating shaft of each vibrator (vibration motor) 600a, 600b is set substantially equal, Specifically, it is set to the inclination angle of about 15deg-45deg, FIG. As shown in A), on the projection surface in the left-right direction of the vibrating body 500, the rotation axis AR1 (center axis of rotation) of the vibrator (vibration motor) 600a and the rotation axis AR2 (center of rotation) of the vibrator (vibration motor) 600b. The angle formed by the axis) is set to about 30 deg to 90 deg.

The vibrating body 500 is supported on the mounting base 400 via four coil springs (first elastic bodies) 401.
At the four corners of the main body 510 of the vibrating body 500, a bottomed cylindrical spring receiving portion 515 is formed with the vertical direction as an axis and the lower end side being an open end, while being aligned with the spring receiving portion 515. Then, one end of the four coil springs 401 is supported on the mounting base 400. Then, by assembling the vibrating body 500 and the mounting base 400 so that the tips of the four coil springs 401 are inserted into the spring receiving portions 515, the vibrating body 500 has four coils on the mounting base 400. It is supported via a spring 401.

Accordingly, the vibrating body 500 is supported by the mounting base 400 as a fixed end so as to be displaceable in the axial direction (vertical direction) of the fixed shaft 300 while elastically deforming the coil spring 401.
In addition, a pair of fixing plates 402a and 402b facing each other along the tangential direction of the fixed shaft 300 are erected on the front side and the rear side of the top surface of the mounting base 400, respectively, and between the pair of fixing plates 402a and 402b. In this, two coil springs (second elastic bodies) 404a and 404b are interposed in a compressed state with a pressure receiving plate 403 interposed therebetween.

At the upper end of the pressure receiving plate 403, a mounting plate 405 for fixing the pressure receiving plate 403 to the lower surface of the main body 510 of the vibrating body 500 is integrally provided. By fixing the mounting plate 405 to the lower surface of the main body 510, When the vibrating body 500 vibrates in the rotational direction around the fixed shaft 300, the position of the pressure receiving plate 403 between the fixed plates 402a and 402b changes, so that one of the two coil springs 404a and 404b extends. The other is configured to shrink.
The basket 700 has a frame member 702 formed by combining pipe-shaped members in a lattice shape, and is finer than the frame member 702, and allows the cleaning liquid and the rinse liquid to enter and exit without dropping an object to be cleaned. The cleaning container 703 is formed of a latticed wire mesh or the like and stores an object to be cleaned.

The frame member 702 is formed with a handle portion 701 that is hooked on the hook 551 of the vibrating body 500 to suspend the basket 700 below the vibrating body 500.
The handle portion 701 is formed by a stay portion 701b extending upward from the left and right end surfaces of the frame member 702, and a plate-like member bent in a mountain shape, and is located at the tip of the stay 701 on the inner side of the stay 701. The handle main body 701c is attached to the handle main body 701c, and the above-described positioning plate member 701a is provided on the handle main body 701c.

When the basket 700 is suspended below the vibrating body 500, the basket 700 is placed so that the handle body 701 c is positioned at the height of the gap between the pressing portion 552 a of the fixing mechanism 552 and the tip portion 551 a of the hook 551. The handle body 701c is positioned between each pressing portion 552a and the tip portion 551a by lifting the basket 700 rearward while lifting in the space on the front side of the vibrating body 500 and maintaining the height thereof. To.
Thereafter, the basket 700 is lowered so that the lower side of the handle main body 701c is supported by the tip portion 551a of the hook 551, and the pressing portion 552a is further lowered to hold the handle between the pressing portion 552a and the tip portion 551a. The main body 701c is sandwiched and fixed. The removal of the basket 700 from the vibrating body 500 is performed in the reverse procedure to the above.

When the basket 700 containing the object to be cleaned is suspended below the vibrating body 500, the fixed shaft 300, the mounting base 400, the vibrating body 500, and the vibrator 600 are integrated together with the upper plate (lifting base) 200 by the lifting motor. The basket 700 is lowered to the cleaning tank or the rinsing tank, so that the basket 700 is immersed in the cleaning liquid or the rinsing liquid. At this time, the basket 700 is pulled by the vibrator 600 and is stored in the basket 700. The cleaning object is vibrated, and the cleaning process and the rinsing process are performed in the vibration state.
Further, when the basket is lifted from the washing tank or the rinse tank and transferred to the next process, when the basket 700 is vibrated by the vibrator 600 and further, hot air is blown to the object to be cleaned in the drying chamber to dry it. In addition, the basket 700 is vibrated by the vibrator 600.

Below, the effect | action and effect of the said vibration mechanism are demonstrated.
Vibrators (vibration motors) 600a and 600b generate centrifugal force vibrations, and since each rotation shaft is inclined and fixed from the horizontal as described above, the vibrator (vibration motor) is on a vertical plane including the rotation shaft. 600 a includes a vibration component that is obliquely pushed upward toward the rear side of the vibrating body 500, and the vibrator (vibration motor) 600 b includes a vibration component that is obliquely thrust toward the upper front side of the vibration body 500.

On the other hand, since the vibrating body 500 is supported so as to be displaceable in the vertical direction and the rotational direction with respect to the fixed shaft 300, the vibration component that pushes up obliquely upward of each vibrator (vibration motor) 600a, 600b is seen from above. Sometimes, it acts as a push-up vibration that raises the vibrating body 500 while twisting it clockwise around the fixed shaft 300.
Since the left and right ends of the basket 700 sandwiching the fixed shaft 300 are suspended from the left and right ends of the vibrating body 500 sandwiching the fixed shaft 300, the basket 700 has the fixed shaft 300 around the same as the vibrating body 500. Pushing vibration that rises while twisting is given.

Here, by applying a torsional vibration around the fixed shaft 300, one of the two coil springs 404a and 404b is extended and the other is contracted, whereby an elastic return force that attempts to return from the torsional state acts. Vibration can be amplified.
Then, the object to be cleaned contained in the basket 700 is subjected to the above-described push-up vibration by the vibrators (vibration motors) 600a and 600b arranged to face each other with the central axis of the basket 700 interposed therebetween. It moves continuously while jumping in the clockwise direction (constant turning direction) around the central axis 700 (fixed shaft 300).

  In addition, if the inclination direction of the rotation shafts of the vibrators (vibration motors) 600a and 600b is reversed from the direction of the embodiment, the object to be cleaned contained in the basket 700 is the central axis (fixed) of the basket 700 as viewed from above. It moves while jumping counterclockwise around the axis 300).

  As described above, if a circular movement vibration is applied such that the object to be cleaned jumps in the basket 700 and moves in the clockwise direction (or counterclockwise direction), a plurality of objects to be cleaned are accommodated in the basket 700 so as to overlap each other. When the object to be cleaned moves to the lower part and the object to be cleaned moves to the upper part, the object to be cleaned maintains a substantially constant position in the basket 700. As compared with the case of applying vibration (for example, omnidirectional vibration), the cleaning (degreasing) action and the rinsing action can be further promoted, and the cleaning time and the rinsing time can be shortened.

  Further, when the basket 700 is pulled up from a state where the object to be cleaned is immersed in the cleaning liquid or the rinsing liquid, the above-described circular movement vibration is applied, and the object to be cleaned jumps in the basket 700 in the clockwise direction (or counterclockwise). ), The draining action is promoted. As a result, the amount of cleaning liquid brought into the rinsing tank is reduced, the consumption of the cleaning liquid can be suppressed, and the rinsing liquid can be prevented from being contaminated with the cleaning liquid, so that the cleaning liquid and the rinsing liquid can be used economically. Energy costs can be reduced by shortening the drying time in the drying chamber.

In addition, a pair of vibrators may be disposed on the front and back of the vibrating body 500, and the vibrators may be disposed on the left and right and front and rear. Here, when the object to be cleaned is moved around in the same direction as in the above embodiment, the rotational axis of the vibrator (vibration motor) 600 disposed on the rear side of the vibrating body 500 is inclined upward to the left, and the front side of the vibrating body 500 The rotation shaft of the vibrator (vibration motor) 600 disposed on the right side may be inclined upward to the right.
Further, the vibrator is not limited to a rotary vibrator that generates centrifugal vibration such as a vibration motor, and a reciprocating vibrator that reciprocates a piston can be used. In the case of using a reciprocating vibrator, the reciprocating direction may be inclined from the vertical toward the direction in which the object to be cleaned circulates in the basket 700.

In addition, a cylindrical basket having a round shape as a portion on which an object to be cleaned is placed can be used as the basket 700. In this case, the vibrating body 500 is also formed in a cylindrical shape, and a fixed shaft is attached to the peripheral wall of the cylindrical vibrating body. A pair of vibrators can be arranged with 300 interposed therebetween, or vibrators can be installed at three locations at equal intervals of 120 deg, for example.
As described above, when the cylindrical vibrator 500 is used, the vibrator 600 is attached so that the rotation axis of the vibrator 600 (the reciprocating direction of the reciprocating vibrator) is parallel to the tangential direction of the vibrator 500. .
In addition, the inclination of the rotary shaft of the rotary vibrator and the inclination of the reciprocating vibrator in the reciprocating direction change the force that moves the object to be cleaned in the circumferential direction and the force that jumps upward. If the rotational axis of the rotary vibrator is made to be horizontal and the reciprocating direction of the reciprocating vibrator is made to be vertical, the jumping height on the object to be cleaned will increase while the jumping distance in the circumferential direction will increase. The object to be cleaned will circulate at a relatively slow speed while jumping high in the basket 700.

On the other hand, when the rotational axis of the rotary vibrator is made vertical and the reciprocating direction of the reciprocating vibrator is made horizontal, the jumping height on the object to be cleaned is reduced while the jumping distance in the circumferential direction is reduced. As the number of objects to be cleaned increases and jumps low in the basket 700, the objects to be cleaned circulate at a relatively high speed.
Note that the jump height and rotation speed vary depending on the weight of the object to be cleaned, and the optimum jump height and rotation speed for the ease of upside down action depends on the type of object to be cleaned (weight, shape, etc.). ), The inclination of the rotating shaft of the rotary vibrator (inclination in the reciprocating direction of the reciprocating vibrator), in other words, the attachment angle of the vibrator 600 can be changed continuously or stepwise. It is preferable to have a structure that can be used.

As a structure in which the inclination (attachment angle) of the vibrator 600 is variable, the inclination angles when the vibrator 600 is fixed as bolt through holes provided in the diaphragms 550a and 550b for fixing the vibrator 600 are different from each other. A structure in which a plurality of sets of through-holes are provided in advance and the shaft inclination (attachment angle) of vibrator 600 is switched to a plurality of stages by selecting a through-hole to be used for bolt fixing can be appropriately employed.
In addition, the cleaning / drying apparatus to which the vibration mechanism according to the present invention is applied is not limited to the cleaning / drying apparatus that performs a series of cleaning, rinsing, and drying. The present invention can also be applied to a cleaning apparatus, a cleaning apparatus that performs a cleaning process including a cleaning process and a rinse process, and a drying apparatus that performs only drying. In addition to a cleaning / drying device that performs cleaning and rinsing treatment by immersing in the cleaning solution in the cleaning tank and the rinsing liquid in the rinsing tank, cleaning / drying that vibrates the object to be cleaned in the shower of cleaning liquid and rinsing liquid It can also be applied to devices.

In the above embodiment, the basket 700 is suspended from the lower part of the vibrating body 500. However, the basket 700 can be held on the upper part of the vibrating body.
Furthermore, in order to further promote the upside down action of the object to be cleaned accommodated in the basket 700, the surface of the basket 700 on which the object to be cleaned is placed, the inner peripheral wall, etc. can be provided with unevenness, inclined surfaces, baffles and the like.
