Embodiment 1 FIG.
FIG. 1 is a side view showing a cleaning apparatus according to this embodiment, and FIG. 2 is a plan view showing a main part of the cleaning apparatus of FIG.
The cleaning apparatus according to this embodiment includes a cleaning unit 3 in which a cleaning path 2 in which a coin 1 as an object to be cleaned descends due to its own weight, and an upper part of the cleaning unit 3. A water supply pipe 4 which is a cleaning liquid supply means for supplying water and a vibrator 5 attached to the cleaning unit 3 below the water supply pipe 4 are provided.
The water supplied from the water supply pipe 4 flows down the washing path 2.
The object to be cleaned is not limited to the coin 1 and may be a pachinko ball, for example.
The cleaning liquid supply means is not limited to the water supply pipe 4, and any means may be used as long as a water supply path is formed and water can be supplied to the cleaning path 2.
The cleaning liquid is not limited to water and may be any liquid that can clean the coin 1.

Above the cleaning path 2, a hopper 6, which is an object storage body for storing a plurality of coins 1, is disposed. The hopper 6 is supported by the dehydrating unit housing 7 and is structurally separated from the cleaning unit 3.
The hopper 6 is not limited to the dehydrating unit housing 7 and may be supported by other members such as a housing (not shown) of the cleaning device, but is housed in the hopper 6 and the hopper 6. It is desirable to support the hopper 6 so that the weight of the coin 1 is not a factor that impedes the vibration of the cleaning unit 3.
The coin 1 accommodated in the hopper 6 is supplied to the cleaning path 2 through the supply port 2a which is the upper end portion of the cleaning path 2.

A dewatering unit housing 7 that covers the lower end of the cleaning unit 3 is attached to the lower part of the cleaning unit 3. Under the dewatering unit housing 7, the washed coin 1 is located outside the cleaning device. And a drain pipe 9 for discharging water flowing out from the cleaning path 2 and water separated from the coin 1 to the outside of the cleaning device.
In addition, what discharges | emits the coin 1 after washing | cleaning outside the washing | cleaning apparatus is not restricted to the discharge pipe 8, Other things may be used.
Moreover, what discharges the water which flowed out from the washing path 2 to the exterior of the washing | cleaning apparatus is not restricted to the drainage pipe 9, Other things may be used.

The cleaning unit 3 includes a bottom plate 10 that is inclined with respect to a horizontal plane, a top plate 11 that is disposed above the bottom plate 10 and faces the bottom plate 10, and extends from both side ends of the bottom plate 10 to the top plate 11. A pair of side plates 12 facing each other is formed, and a cleaning path 2 that is a rectangular path having a square cross section is formed from the bottom plate 10, the top plate 11, and the side plates 12.
The cleaning unit 3 is not limited to the cleaning unit 3 having the bottom plate 10, the top plate 11, and the pair of side plates 12.
The water supply pipe 4 is connected to the top plate 11.

The vibrator 5 is a Langevin type ultrasonic vibrator in which a piezoelectric element is sandwiched between metal bodies. The vibrator 5 is in surface contact with the lower surface of the bottom plate 10 of the cleaning unit 3 and is made of a bolt or a heat-resistant epoxy resin. It is fixed using an adhesive or a filler.
In addition, if there is a gap between the vibrator 5 and the bottom plate 10, the transmission efficiency of vibration from the vibrator 5 to the bottom plate 10 is reduced, and the attenuation of the transmitted vibration is increased, and the bottom plate 10 facing the gap. Or the heat generation from the vibrator 5 increases.
The surface on the upper surface side of the bottom plate 10 is a vibration surface 13 that vibrates when the vibrator 5 vibrates.
The vibrator 5 is connected to a high frequency power source (not shown), vibrates by a high frequency current supplied from the high frequency power source, vibrates the bottom plate 10 of the cleaning unit 3, and the vibration surface 13 vibrates.

Between the hopper 6 and the cleaning unit 3 and on the top plate 11 side, a cylindrical supply roller 14 is rotatably disposed adjacent to the supply port 2a. 6 is supported.
The supply roller 14 is not limited to the hopper 6 and may be supported by other members.
Further, the supply roller 14 is not limited to the top plate 11 side, and may be attached to the bottom plate 10 side or the side plate 12 side.
The distance between the outer peripheral surface of the supply roller 14 and the upper surface of the bottom plate 10 is larger than the thickness of one coin 1 and smaller than the thickness of two stacked coins 1.
In the supply port 2 a, the distance between the upper surface of the bottom plate 10 and the lower surface of the top plate 11, which is the short dimension, is larger than the thickness of one coin 1 and more than the thickness of two stacked coins 1. It is formed small.
The supply roller 14 is connected to a supply roller motor 16 via a supply roller rotating shaft 15, and by driving the supply roller motor 16, the supply roller 14 raises the coin 1 in contact with the supply roller 14. That is, it rotates in the direction of arrow A in FIG.

On the upper surface side of the bottom plate 10, two wire-shaped guide rails 17 having an upper end adjacent to the hopper 6 and extending in the longitudinal direction of the bottom plate 10 are provided.
Each guide rail 17 is supported by a support member (not shown) extending from the bottom plate 10 or the top plate 11.
Further, the respective guide rails 17 are arranged in the short direction of the bottom plate 10 so that the coins 1 descend on the bottom plate 10 in three rows.
Note that the coin 1 is not limited to three rows, but may be any other number of rows. For example, when the coin 1 is in one row, the guide rail 17 is not necessary.

The top plate 11 is cut off at the lower end of the cleaning unit 3 so that the upper surface of the bottom plate 10 is exposed.
The area of the bottom plate 10 (the area where the top plate 11 is not present and the upper surface is exposed) at the lower end of the cleaning section 3 is a drainage section 10a formed in a net shape, and the water flowing down the cleaning path 2 is drained. It falls from the part 10a.
As a result, the coin 1 descending the cleaning path 2 is supported by the drainage unit 10 a, and the water flowing down the cleaning path 2 falls from the drainage unit 10 a toward the bottom surface of the dehydrating unit housing 7.
The water dropped toward the bottom surface of the dehydrating unit housing 7 passes through the drain pipe 9 and is discharged to the outside of the cleaning device.

A drainage port (not shown) is formed in the cleaning channel 2 near the supply port 2a, and water from the drainage port finally joins the drainage pipe 9 through a drainage channel (not shown).
The amount of water supplied from the water supply pipe 4 to the cleaning path 2 is the sum of the amount of water discharged from the lower end of the cleaning path 2 and the amount of water discharged from the drain outlet.
Therefore, even when the amount of water flowing down the cleaning path 2 varies with the change in the number of coins 1 descending the cleaning path 2, the amount of water discharged from the drainage port is increased or decreased. Even if the amount of water supplied from the water supply pipe 4 is constant, the water surface 18 of the cleaning path 2 is maintained.
The amount of water supplied from the water supply pipe 4 is adjusted by adjusting the opening degree of the valve (including opening / closing adjustment), or by directly controlling the rotational speed of the pump, which will be described later. May be more reliably maintained.
Thereby, the water surface 18 of the cleaning path 2 is constant, and the area of the cleaning path 2 from the vicinity of the supply port 2a to the lower end of the top plate 11 is always filled with water.
Therefore, in the region of the cleaning path 2 from the vicinity of the supply port 2a to the lower end of the top plate 11, the coin 1 is immersed in water and the vibration surface 13 is also immersed in water.

The drain pipe 9 and the water supply pipe 4 are connected by a connection pipe (not shown), and a pump (not shown) for sending water from the drain pipe 9 toward the water supply pipe 4 is connected to the connection pipe, A filter (not shown) for removing foreign substances contained in the water passing through the connection pipe is attached.
Thereby, the water discharged by the drain pipe 9 is circulated and supplied to the water supply pipe 4.
Note that new water may always be supplied to the water supply pipe 4 without circulating the water discharged from the drain pipe 9.
In this case, although the amount of water used increases, the power required to circulate the water can be reduced, and the reattachment of foreign matter to the coin 1 caused by circulating and reusing the water can be reduced. Therefore, the cleaning effect of the coin 1 can be improved.

The distance between the bottom plate 10 and the top plate 11 is slightly thicker than the thickness of the coin 1 and is about several millimeters. When the vibration frequency of the vibrator 5 is 20 kHz, the wave passing through water has a wavelength of about Since it is 7.5 cm (when the sound speed in water is 1500 m / s), no vibration standing wave is formed in the water between the bottom plate 10 and the top plate 11.
The inventor of the present application has found that the coin 1 can be effectively washed by making the vibration standing wave impossible.
As a result, the impact of the cavitation that occurs near the vibration surface 13 (the phenomenon that bubbles containing water vapor or vacuum in water due to decompression) burst, and the acoustic that the cavitation bubbles generate in the direction perpendicular to the vibration surface. Carrying by the straight flow is a main factor, and the surface of the coin 1 descending the cleaning path 2 can be effectively cleaned.
Further, in the cleaning path 2, vibration is transmitted from the vibration surface 13 to the coin 1 through water, and the coin 1 itself also vibrates. Therefore, not only the surface facing the vibration surface 13 of the coin 1 but also the top of the coin 1. The surface facing the plate 11 is also cleaned.

A holding plate 19, which is a holding means for holding the coin 1 descending the cleaning path 2, is attached to the lower end of the drainage section 10 a that is downstream of the cleaning path 2.
The lower end of the guide rail 17 extends to the vicinity of the holding plate 19. Note that the lower end of the guide rail 17 and the holding plate 19 may be connected.
When coins 1 are continuously lowered onto the cleaning path 2, the lowermost coin 1 is held by the holding plate 19, so that the plurality of coins 1 are arranged in contact with each other in the cleaning path 2.
Thereby, the coins 1 are also arranged in the region of the cleaning path 2 filled with water from the vicinity of the supply port 2 a to the vicinity of the lower end of the top plate 11.

On the lower surface side of the drainage part 10 a, a discharging means for discharging the lowermost coin 1 held by the holding plate 19 from the holding plate 19 is provided.
The discharging means includes a striking portion 20 that can be advanced and retracted toward the lowermost coin 1 held by the holding plate 19, and a column that is fixed to the dewatering portion housing 7 and supports the striking portion 20 via a striking spring 21. And an impact spring fixing portion 22 having a shape.
A through hole (not shown) through which the striking portion 20 can pass is formed in the drainage portion 10a.
The striking portion 20 is formed in a cup shape, and is arranged so that the bottom portion faces the bottom plate 10 side.
The striking spring 21 and the striking spring fixing portion 22 are inserted into the striking portion 20.
The striking portion 20 has a reaction spring 23 at the end on the bottom plate 10 side. When the striking portion 20 strikes the lowest coin 1 held by the holding plate 19, the reaction spring 23 is Then, the lowermost coin 1 held by the holding plate 19 is contacted.

On the outside of the striking portion 20, a rotatable striking drive gear 24 is provided so as to be able to contact the striking portion 20.
The striking drive gear 24 is formed in a cylindrical shape, and a flat surface portion 24a cut along the axial direction is formed at the peripheral portion.
The striking drive gear 24 is connected to a striking drive motor 26 via a striking drive shaft 25, and the striking drive gear 24 is held by the striking portion 20 that is in contact with the striking drive gear 24 by the driving of the striking drive motor 26. It rotates in the direction away from the plate 19, that is, in the direction of arrow B in FIG.
The striking drive gear 24, the striking drive shaft 25, and the striking drive motor 26 are supported by the dewatering unit casing 7 via support means (not shown).
The striking drive gear 24, the striking drive shaft 25, and the striking drive motor 26 are not limited to the dewatering unit housing 7, and may be supported by other members.
A striking portion gear 27 that can mesh with the striking drive gear 24 is attached to the surface of the striking portion 20 on the striking drive gear 24 side.
When the striking drive gear 24 is engaged with the striking portion gear 27, the striking drive gear 24 rotates so that the striking portion 20 is held by the holding plate 19 against the elastic force of the striking spring 21. Move in a direction away from the lowest coin 1.
On the other hand, when the flat surface portion 24 a of the hitting drive gear 24 faces the hitting portion gear 27, the hitting drive gear 24 and the hitting portion gear 27 do not mesh with each other, and the hitting portion 20 is held at the lowermost stage held by the holding plate 19. Is moved by the elastic force of the striking spring 21 in the direction of contact with the coin 1.
As a result, the striking drive gear 24 rotates with the striking drive gear 24 engaged with the striking portion gear 27, and the striking portion 20 is held by the holding plate 19 against the elastic force of the striking spring 21. After being separated from the lowermost coin 1, the striking drive gear 24 is further rotated and the flat portion 24 a of the striking drive gear 24 faces the striking portion gear 27, so that the striking portion 20 is elastic of the striking spring 21. The lowermost coin 1 held on the holding plate 19 is struck by force, and the coin 1 is pushed off the holding plate 19.
After the hitting unit 20 hits the lowermost coin 1 held by the holding plate 19, the hitting drive gear 24 rotates again, and when the hitting drive gear 24 meshes with the hitting unit gear 27, the hitting unit 20 again separates from the lowermost coin 1 held by the holding plate 19 against the elastic force of the striking spring 21.
In this way, the hitting unit 20 hits the coin 1 held on the holding plate 19 at every predetermined time, and the coin 1 is pushed off the holding plate 19.
The timing at which the coin 1 is ejected from the holding plate 19 can be adjusted by adjusting the rotation speed of the batting drive gear 24.
Since the coins 1 are arranged in three rows in the cleaning path 2, three hitting portions 20 that can advance and retreat toward the lowest coin 1 held by the holding plate 19 are arranged.
Each striking portion 20 advances and retreats toward the lowermost coin 1 held by the holding plate 19 by the rotation of one striking drive gear 24, but the position of the flat portion 24a of the striking drive gear 24 is adjusted. The phase of movement of each hitting unit 20 is shifted by 120 degrees.
Thereby, the fluctuation | variation of the rotational torque of the striking drive shaft 25 can be reduced, and the life of the striking drive motor 26 can be extended.
Note that the position of the flat surface portion 24 a of the impact driving gear 24 may not be adjusted for each impact portion 20.
Further, an opening through which the striking portion 20 passes is formed in the dewatering portion casing 7, and the striking spring 21, the striking spring fixing portion 22, the striking drive gear 24, the striking drive shaft 25, the striking drive motor 26, etc. You may provide in the outer side of the housing | casing 7. FIG. In this case, the occurrence of corrosion of each member due to water can be suppressed.

The dewatering unit housing 7 is provided with a collision plate 7a on which the coin 1 hit by the hitting unit 20 collides.
The hitting unit 20 hits the eccentric position of the coin 1 held by the holding plate 19, and the coin 1 hit by the hitting unit 20 flies toward the collision plate 7a while rotating.
A net-shaped midsole 28 is attached to the inside of the dehydrating unit housing 7 and below the collision plate 7a, and the coin 1 that has collided with the collision plate 7a and dropped is transferred to the midsole 28. It falls and further dehydrated, and moves to the discharge pipe 8.
Since the collision plate 7a is consumed by the collision of the coin 1, it can be detached from the dehydrating unit housing 7 and can be replaced with a new collision plate 7a.

A drying device (not shown) for drying the coin 1 by applying warm air to the coin 1 is attached to the discharge pipe 8.
The drying device is not limited to drying the coin 1 by applying warm air to the coin 1, and for example, the coin 1 may be dried by electromagnetic induction heating of the coin 1. Electromagnetic induction heating is more energy efficient than using warm air, and the coin 1 can be dried in a short time.

Next, the operation of the cleaning apparatus according to this embodiment will be described.
First, water is supplied from the water supply pipe 4 to the cleaning path 2, and the cleaning path 2 from the vicinity of the supply port 2 a to the vicinity of the lower end of the top plate 11 is always filled with water.
Next, the vibrating surface 13 of the bottom plate 10 is vibrated by the vibrator 5.
In this state, the coin 1 is supplied from the hopper 6 to the cleaning path 2 through the supply port 2a.
The coin 1 supplied to the cleaning path 2 descends the cleaning path 2 by its own weight, and the cavitation bubbles generated in the water near the vibration surface 13 by the vibration of the vibrator 5 are carried by the straight acoustic flow. The coin 1 is washed by colliding with the coin 1.
Further, the coin 1 is also washed by an impact generated when a cavitation bubble bursts due to water flow or sound pressure caused by a straight acoustic flow.
The coin 1 descending the cleaning path 2 is held by the holding plate 19 at the lower end of the cleaning path 2.
The coin 1 held on the holding plate 19 is thrown away and dehydrated by hitting by the hitting unit 20, and further dehydrated by the rotation of the coin 1 generated by hitting an eccentric position by the hitting unit 20.
Further, the hit coin 1 is further dehydrated by the collision by the collision plate 7a.
The water separated from the coin 1 adheres to the inner wall or the like of the dewatering unit housing 7 and flows to the drainage pipe 9 through the drainage groove 7b formed on the inner wall of the dewatering unit housing 7.
The dewatered coin 1 passes through the discharge pipe 8, is dried by the drying device, and is then discharged to the outside of the cleaning device.

As described above, according to the cleaning device of this embodiment, water is supplied from the water supply pipe 4 to the cleaning path 2 so that the coin 1 descending the cleaning path 2 is immersed, and the vibrator 5 is cleaned. By vibrating the vibration surface 13 of the path 2, the water in the cleaning path 2 vibrates, so that the coin 1 is immersed in the water without the transport means for transporting the coin 1, and the water is vibrated to oscillate the coin 1. Cleaning can be achieved, and the size and weight of the cleaning device can be reduced.
Moreover, since it is not necessary to provide a washing tank, the washing apparatus can be further reduced in size and weight.
Further, since water flows down the cleaning path 2, foreign matter separated from the coin 1 can be prevented from adhering to the cleaning path 2, and the coin 1 descending the cleaning path 2 due to the foreign matter can be prevented from clogging. Moreover, the reattachment of the foreign matter to the coin 1 can be suppressed.
In addition, since the vibration surface 13 of the cleaning path 2 vibrates, it is possible to further suppress the foreign matter separated from the coin 1 from adhering to the cleaning path 2 and to prevent the coin 1 itself from sticking to the vibration surface 13. can do.
Further, since the coins 1 descending the cleaning path 2 are prevented from being clogged, a plurality of coins 1 can be successively cleaned.

Further, since the holding plate 19 holds the coin 1 descending the cleaning path 2 and the hitting unit 20 discharges the coin 1 held by the holding plate 19 from the holding plate 19 every predetermined time, the cleaning path The residence time of the coin 1 in 2 can be adjusted.
Thereby, the washing | cleaning time of the coin 1 can be lengthened, without enlarging a washing | cleaning apparatus.
Further, since the coin 1 at the lowermost stage of the cleaning path 2 is held by the holding plate 19, the coins 1 are cleaned by connecting a plurality of coins 1 to increase the storage density of the coins 1 in the cleaning path 2. The coin 1 can be cleaned without enlarging the cleaning device.

  Further, since the hitting unit 20 hits the coin 1 held on the holding plate 19 and pushes the coin 1 off the holding plate 19, the coin 1 can be discharged from the cleaning unit 3 and the coin 1 can be dehydrated. .

  Further, the supply port 2a of the cleaning path 2 is formed so that the dimension in the short direction is larger than the thickness of one coin 1 and smaller than the thickness of the two coins 1 stacked. Instead, it can be reliably supplied to the cleaning path 2, and the coin 1 can be cleaned and lowered in the cleaning path 2 more reliably.

  In addition, a supply roller 14 is disposed between the hopper 6 and the cleaning unit 3, and the supply roller 14 rotates in a direction to raise the coin 1 that has come into contact. Therefore, coins in the hopper 6 and in the vicinity of the supply port 2 a are disposed. 1 can be suppressed, and the coin 1 can be reliably supplied to the cleaning path 2.

In this embodiment, the cleaning unit 3 is inclined, but may be erected vertically.
In this case, since it becomes difficult for the weight of the coin 1 to be directly applied to the vibration surface 13, the vibration surface 13 is more likely to vibrate, and the vibration surface 13 can be vibrated with less power.

In this embodiment, the cleaning unit 3 in which the linear cleaning path 2 is formed has been described. However, the cleaning unit 3 in which the curved cleaning path 2 is formed may be used.
For example, it may be a cleaning unit 3 in which a cleaning path 2 in which the upstream side is vertical and the downstream side is horizontal is formed. In this case, since the coin 1 has the same descending distance, the speed of the coin 1 on the downstream side can be reduced as compared with the cleaning unit 3 in which the inclined linear cleaning path 2 is formed. Even immediately after the coin 1 starts to be supplied to the cleaning path 2, the holding plate 19 can reliably hold the coin 1.

In this embodiment, the holding plate 19 has been described as an example of the holding means. However, the holding plate 19 is not limited to this, and any holding means may be used as long as it can temporarily prevent the coin 1 from being discharged.
For example, it may be two bars that stand on the bottom plate 10 with an interval shorter than the diameter of the disk of the coin 1.
In this case, since the foreign material smaller than the distance between the two bars is not held by the two bars, the coin 1 can be held and the foreign object and the coin 1 can be selected.

  Further, in this embodiment, the striking unit 20 that strikes the lowermost coin 1 that is separated from the bottom plate 10 by the driving of the striking drive gear 24 and is held by the holding plate 19 by the elastic force of the striking spring 21 has been described. Of course, the present invention is not limited to this, and any other type can be used as long as it can strike and discharge the lowest coin 1 held by the holding plate 19.

In this embodiment, the hitting unit 20 that hits the eccentric position of the lowermost coin 1 held by the holding plate 19 has been described. However, the center position of the lowermost coin 1 held by the holding plate 19 is determined. The hit | damage part 20 which hits may be sufficient.
In this case, since the rotation of the coin 1 is reduced and the dehydration effect due to the rotation of the coin 1 is reduced, dehydration spots due to the portion of the coin 1 are larger than in the case where the coin 1 is rotated, but it cannot be dehydrated. Absent.
In addition, the coin 1 can be rotated by the collision of the coin 1 with the collision plate 7a, and it is not always necessary to hit the eccentric position of the coin 1.

In this embodiment, the hitting unit 20 that hits either the front surface or the back surface of the coin 1 has been described. However, the hitting unit 20 that hits the outer peripheral surface of the coin 1 may be used.
For example, for each row of coins 1, the drainage portion 10 a is twisted so that the coin 1 stands at a position where the holding plate 19 is held.
Since the hitting unit 20 hits the outer peripheral surface of the coin 1, it becomes easy to dehydrate from the front surface and the back surface of the coin 1.

In this embodiment, only one vibrator 5 attached to the bottom plate 10 has been described. Of course, the vibrator 5 is not limited to this. For example, a plurality of vibrators 5 attached to the bottom plate 10 may be used. Alternatively, the vibrator 5 attached to the top plate 11 may be used. Further, the vibrator 5 attached to both the bottom plate 10 and the top plate 11 may be used.
When the vibrator 5 is attached to both the bottom plate 10 and the top plate 11, both front and back surfaces of the coin 1 are easily cleaned. In this case, for example, the vibrator 5 is attached to the top plate 11 on the upstream side of the cleaning unit 3, and the bottom plate 10 is shifted downstream from the region facing the vibrator 5 attached to the top plate 11. The vibrator 5 may be attached to the cleaning unit 3. Thereby, vibration interference can be reduced, and the vibrator 5 can be vibrated efficiently.
Further, the vibrator 5 is not limited to a circular cross section, and may be a ring shape or a rectangular shape, for example.
The vibrator 5 is not limited to the Langevin type, but may be a bending type that vibrates in a direction parallel to the vibration surface 13.
In this case, it is easy to increase the vibration surface of the vibrator 5, and a wide vibration surface 13 can be vibrated with a single vibrator 5. Moreover, since it is not clamped with a metal body, the height of the vibrator 5 can be reduced, and the cleaning device can be reduced in size and weight.

Moreover, in this embodiment, although the water supply pipe 4 attached to the top plate 11 was demonstrated, the water supply pipe 4 attached to the bottom plate 10 or the side plate 12 may be sufficient. Moreover, the water supply pipe 4 attached to multiple places may be sufficient. Furthermore, the water supply pipe 4 attached to the hopper 6 may be sufficient.
For example, the water supply pipe 4 may be attached to each row of coins 1 separated by the guide rails 17. In this case, since water is supplied for each row of coins 1, the coins 1 can be sufficiently immersed.

  Further, in this embodiment, the wire-shaped guide rail 17 has been described, but a plate-shaped guide rail 17 may be used. However, in the case of the plate-shaped guide rail 17, if there is no water supply pipe 4 for each row of coins 1, it is necessary to form an opening through which water passes so that all the rows of coins 1 can flow. is there. Further, it is desirable not to fix the guide rail 17 to the vibration surface 13 so as not to hinder the vibration of the vibration surface 13. For example, it is better to support the guide rail 17 with the top plate 11 or the hopper 6.

Moreover, although the washing | cleaning part 3 which has the baseplate 10, the top plate 11, and the side plate 12 and in which the rectangular washing path 2 was formed was demonstrated, the washing | cleaning part 3 which does not have the top plate 11 may be sufficient.
