Description

For example, the present invention can remove dust and powder adhering to various objects to be cleaned such as parts having a relatively complicated shape to which toner used in an electrophotographic image forming apparatus such as a copying machine and a laser printer is attached. related to dry cleaning equipment for removing by using a solid cleaning medium without using a solvent, in particular, those related to the dry cleaning equipment, which can improve the workability was treated successively introducing the cleaning object is there. Further, a method dry cleaning apparatus and dry cleaning of the present invention, or dry cleaning of electronic substrates such as adherent dust, Ru can also be used for cleaning the powder processing apparatus and the like.

  In office equipment manufacturers such as copiers, facsimiles, and printers, in order to realize a resource-recycling society, used products or units are collected from users, disassembled, cleaned, reassembled, reused as parts, or used as resin materials. We are actively engaged in recycling activities. In order to reuse the parts used in these products or units, it is necessary to remove and clean the toner that is fine particle powder adhering to these units and parts. Reducing cost and environmental burden is a big issue.

In the case of a wet cleaning method using water or a solvent to remove dirt such as toner adhering to these parts and units, the energy consumption and environmental load of waste liquid processing including toner and drying processing after cleaning are reduced. The problem is that it is large and expensive.
Also, in the case of dry cleaning methods using air blow, cleaning capability is not sufficient for toner with strong adhesion, and post-processing such as wiping with a manual cloth is necessary, so cleaning is a bottleneck process in product reuse and recycling It is one of. Furthermore, the blast cleaning using dry ice has a problem that the running cost is high and the environmental load is large because dry ice is consumed in large quantities.

In order to solve these problems, the dry cleaning apparatus disclosed in Patent Document 1 and Patent Document 2 removes charge while stirring in a rotating cylinder together with an elastically deformable contact member together with an elastically deformable contact member. We try to remove it by weakening the adhesion of dust attached to things.
In addition, as disclosed in Patent Document 3, steel, aluminum, stainless steel spheres or finely cut pieces of wire rods are sprayed onto the object to be processed to separate the deposits from the object to be cleaned. As disclosed in Document 4, a shot blasting method is also used in which a granular solid is mixed in a high-speed air stream and collides with the surface of the resin container to remove dirt from the resin container.

Further, in the dry cleaning method disclosed in Patent Document 5, a particulate cleaning medium that adsorbs fine particles is introduced into a container to be cleaned, a cleaning nozzle is inserted into an opening of the container to be cleaned, and a high-speed air flow is introduced into the cleaning container. Blow out the cleaning nozzle, blow up the cleaning medium in the cleaning container, remove the fine particles adhering to the inner surface of the cleaning container with the blown particulate cleaning medium, and make the cleaning medium collide with the mesh at the tip of the cleaning nozzle Then, the fine particles adsorbed on the cleaning medium are separated and filtered to regenerate the cleaning medium, and the regenerated cleaning medium is blown again with an air flow and repeatedly cleaned.
Further, in Patent Document 6, in addition to the apparatus disclosed in Patent Document 5, a configuration is also proposed in which the regeneration of the cleaning medium is performed simultaneously with the flight of the cleaning medium and the suction of the cleaning medium.
Patent Documents 5 to 11 also propose a blast cleaning method that uses a flexible cleaning medium to make it difficult to damage the object to be cleaned or to prevent deformation of the object to be cleaned.
Further, Patent Document 12 proposes a cleaning method using a flaky cleaning medium in order to improve cleaning efficiency.

Japanese Patent No. 3288462 Japanese Patent No. 4014132 JP 2005-193958 A Japanese Patent No. 2889547 Japanese Patent No. 3468995 JP 2005-329292 A JP 2004-106100 A JP 60-188123 A Japanese Patent Laid-Open No. 04-059087 Utility Model Registration No. 2515833 Japanese Unexamined Patent Publication No. 07-088446 JP 2007-29945 A

The dry cleaning apparatus disclosed in Patent Document 1 and Patent Document 2 described above has a problem that the contact force between the contact member and the object to be cleaned by stirring is not sufficient, and it is difficult to remove dust with strong adhesion. is there.
In the dry cleaning apparatus disclosed in Patent Document 3, it is necessary to increase the cleanliness of the cleaning medium in order to improve the cleaning quality. However, the centrifugal separation action by the swirling airflow (cyclone method) has insufficient separation performance. It was. Further, in order to further improve the cleaning quality, it is necessary to replace the cleaning medium on which the toner is adsorbed many times, and there is a problem that the cleaning efficiency is poor and a large amount of cleaning medium is required.

  The dry cleaning apparatus disclosed in Patent Document 4 and Patent Document 5 uses small pieces of metal spheres and finely cut wires or granular solids as a cleaning medium, and thus not only removes dirt on the object to be cleaned. It was not applicable when the surface of the object to be cleaned was scraped and roughened into a satin-like shape, and scratches on the object due to cleaning were not allowed.

The dry cleaning apparatus disclosed in Patent Document 6 performs regeneration by flying the cleaning medium and sucking the cleaning medium at the same time, and is an effective means for a small volume such as cleaning in a container. Because the energy of flying the cleaning medium is dispersed, the stagnation of the cleaning medium does not fly and stays in the cleaning tank with a large volume where the object to be cleaned is introduced and moved. It is difficult to fly and regenerate, and the cleaning ability may be reduced.
The dry cleaning apparatuses disclosed in Patent Documents 7 to 11 have a problem that the time required for cleaning is long and sufficient cleaning cannot be performed on the adhered particles having strong adhesion.

Since the dry cleaning apparatus disclosed in Patent Document 12 causes the cleaning medium to fly into the open space in the cleaning process, as shown in FIG. 8, the cleaning medium flies while spreading on the air current, and the cleaning medium accelerates. The cleaning medium away from the center position of the nozzle of the means decelerates, resulting in a problem that the amount of the cleaning medium reaching the speed contributing to the cleaning is reduced and the cleaning efficiency is lowered.
Further, as shown in FIGS. 9A to 9C, the cleaning medium exhibits an excellent cleaning ability because the collision energy concentrates on the edge portion due to the collision of the edge in the cleaning process, whereas FIG. As shown in (a) to (c), there is a phenomenon that the collision energy is dispersed in the collision on the surface other than the edge, and thus the cleaning ability is reduced. In the method shown in Patent Document 12, the cleaning medium flies. The collision direction is not constant, and there are cases where the cleaning time and the removal ability are insufficient for the object to be cleaned with strong adhesion.
Further, as shown in FIG. 11, when cleaning an object to be cleaned having a narrow groove, since the approach angle of the cleaning medium is limited, the cleaning medium whose collision direction is not constant cannot enter the groove, In some cases, the cleaning time and removal capacity were insufficient.

The present invention has been made in view of the above circumstances, and by improving the movement speed and cleanliness by controlling the flight direction and posture of the dry cleaning medium, the cleaning quality and cleaning efficiency are improved and the width is improved. in which an object to provide a dry cleaning equipment using dry cleanable cleaning medium without or generate leaving cleaning or damage even complex shaped parts small grooves are formed in the Oh Ru.

In order to achieve the above object, the present invention employs the following solutions.
According to the first aspect of the present invention, a cleaning tank containing a resin film and a flaky resin film flying in the cleaning tank collide with the object to be cleaned by a high-speed air current, and dust adhered to the object to be cleaned. Cleaning medium accelerating means for removing deposits of powder and powder, cleaning medium regeneration means for regenerating the resin film by sucking and removing the deposits adhering to the resin film colliding with the object to be cleaned, And a circulation means for conveying the resin film accommodated in the washing tank to the cleaning medium acceleration means, and rectifies the resin film conveyed by the high-speed airflow from the cleaning medium acceleration means. And a cleaning medium rectifying means for preventing disturbance from other than the cleaning medium accelerating means, the cleaning medium rectifying means having an uneven shape less than or equal to the resin film size along the flow direction of the high-speed airflow. When the high-speed airflow of the cleaning medium accelerating means passes through the cleaning medium rectifying means and collides with the object to be cleaned, the uneven shape reduces the contact resistance with the resin film. It is characterized by that.

According to a second aspect of the present invention, in the dry cleaning apparatus according to the first aspect of the present invention, the cleaning medium rectifying unit is provided with a movable unit that moves within a predetermined range.

In the first aspect of the present invention, the cleaning medium accelerating unit includes the cleaning medium rectifying unit that rectifies the resin film conveyed by the high-speed airflow from the cleaning medium accelerating unit and prevents disturbance from other than the cleaning medium accelerating unit. The high-speed airflow from is not weakened by the disturbance airflow, and a large amount of the cleaning medium can be intensively transported to the object to be cleaned in order to limit the ejection range. As a result, the cleaning efficiency increases, and as a result, the environmental load in the cleaning process can be reduced.
Further, by causing the high-speed airflow of the cleaning medium accelerating means to pass through the cleaning medium rectifying means and collide with the object to be cleaned, almost all of the cleaning medium is concentrated in a limited range near the wall surface of the cleaning medium rectifying means. Therefore, very high cleaning quality can be obtained. In addition, since the cleaning medium rectifying unit can fly the cleaning medium at an angle where it is difficult for the single cleaning medium accelerating unit to collide with the cleaning medium rectifying unit, even a cleaning object having a complicated shape can eliminate cleaning unevenness and obtain high cleaning quality. .
The cleaning medium rectifying means has an irregular shape that is not larger than the size of the cleaning medium along the flow direction of the high-speed airflow, thereby forming a space between the wall surface of the cleaning medium rectifying means and the cleaning medium, and The contact resistance can be reduced, and the cleaning medium can be efficiently transported and a large amount of cleaning medium can be transported by the airflow flowing in the groove. In addition, the airflow rectification effect is added by the plurality of grooves, so that turbulence is less likely to occur and the force of the airflow is less likely to be attenuated, so that the cleaning medium can be efficiently transported and allowed to fly. Further, the contact area between the wall surface and the cleaning medium is reduced by the groove, and the cleaning medium is difficult to stick to the wall surface, and the cleaning medium can be efficiently transported and flying.

In the invention described in claim 2, by having a movable means for moving the washing medium rectifying means in a predetermined range, it is possible to increase the cleaning area, a large amount of cleaning medium with various parts of the object to be cleaned Ru can be transported to concentrate.

Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing the mechanism of a dry cleaning apparatus according to an embodiment of the present invention. FIG. 1A is a perspective view of the dry cleaning apparatus, and FIG.
This dry cleaning apparatus 1 removes various dusts such as toner adhering to an object to be cleaned 9 by a cleaning medium 8 that flows by a high-speed air stream, and is cleaned by a cleaning tank 2, a circulation means 3, a cleaning medium acceleration means 4, and a cleaning medium. It has a medium regeneration means 5, a cleaning medium rectification means 6, and a dust collector (dust collector) 7.
The cleaning medium 8 used in the dry cleaning apparatus 1 is formed from a solid such as metal, ceramics, synthetic resin, sponge, cloth, or the like, solid, rod-shaped, cylindrical, fibrous, or flaky solid, What is necessary is just to select according to the characteristics, such as a material, and the particle size and adhesion strength of the dust adhering to the cleaning object 9. As the flaky cleaning medium 8, an object having an area of 1 mm ^{2 to} 1000 mm ² and a thickness of about 1 μm to 500 μm may be used. For example, a resin film piece, a cloth piece, a paper piece, or the like is used to remove toner powder from a synthetic resin or metal component having an average particle diameter of 5 μm to 10 μm used in an electrophotographic image forming apparatus. It is desirable to use a lamellar cleaning medium 8 such as a metal flake.

  When a flaky cleaning medium is used as the cleaning medium 8, the contact force concentrates on the edge of the cleaning medium when it collides with the object to be cleaned from the end of the cleaning medium as shown in FIG. Despite the small mass, the force required to remove dust can be obtained. Also, since the contact force against the object to be cleaned increases and the force is deflected, the force is not applied to the object to be cleaned, unlike a general blast shot material or an abrasive for barrel processing. The object to be cleaned is not damaged. In addition, when the flaky cleaning medium collides with the object to be cleaned, the viscous resistance received from the air acts greatly, resulting in inelastic collision, which is unlikely to bounce. It moves while contacting a large area of the object to be cleaned, and a force parallel to the contact surface is applied to the dust such as toner particles adhering to the object to be cleaned by scraping action or rubbing action due to this contact, and small The dust can be separated from the object to be cleaned by force to increase the cleaning efficiency.

  The first embodiment of the present invention will be described below.

[Device configuration]
[Washing tank]
1 (a) and 1 (b), the cleaning tank 2 is formed of a cylindrical hollow body when viewed from the side, has a cleaning object input port for supplying the cleaning object 9 on the side surface, and the like. An openable / closable lid is provided at the object insertion port. An opening is formed in a part of the inner wall surface in the circumferential direction of the cleaning tank 2, and the cleaning medium regeneration means 5, the cleaning medium acceleration means 4, and the circulation means 3 are provided in the opening. When the cleaning tank 2 has an ideal cylindrical shape as shown in FIGS. 1A and 1B, a circulation path is formed by the inner wall surface in the circumferential direction. Since the return airflow to the cleaning medium regeneration means 5 also serves as a circulation means, it is not necessary to prepare a circulation means separately. Further, the shape of the cleaning tank 2 is preferably a sealed type such as a cylindrical shape in consideration of leakage outside the cleaning tank, but the size of the cleaning object 9 is overwhelmingly large and the cleaning surface of the cleaning object 9 is limited. If it is within the specified range and can be sealed using the object 9 to be cleaned, an open type such as a semi-cylindrical shape may be used.

[Circulation means]
The circulation means 3 has an air blow nozzle for conveying the cleaning medium 8 to the cleaning medium acceleration means 4, and the cleaning medium is supplied by compressed air supplied from a compressed air source (not shown) such as a compressor, a blower or a pressure tank. It ejects toward the acceleration means 4.

[Cleaning medium acceleration means]
The cleaning medium accelerating means 4 has an accelerating nozzle, and performs cleaning by ejecting compressed air supplied from a compressed air source (not shown) such as a compressor, a blower, or a pressure tank from the accelerating nozzle toward the object 9 to be cleaned. The medium 8 is made to collide with the object 9 to be cleaned.

[Cleaning medium regeneration means]
As shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b), the cleaning medium regeneration means 5 is a separation member disposed on a part of the circumferential inner wall surface of the cleaning tank 2. A closed space is formed by the hood, and the formed closed space is connected to a dust collector (dust collector) 7 having a negative pressure generation source by a suction pipe 52 such as a hose, and the inside of the hood is made negative pressure. The separation member has a large number of small holes and slits through which gas and powder can pass but the cleaning medium 8 cannot pass through. The separation member is formed of a porous member 51 such as a wire mesh, a plastic mesh, a mesh, a punch metal plate, and a slit plate. Then, the dust separated from the object 9 to be cleaned, the cleaning medium 8 that has collided with the object 9 to be worn and has been worn or chipped, and the cleaning medium 8 whose elasticity has deteriorated due to long-term use are discharged.

[Cleaning medium rectification means]
As shown in FIGS. 1A and 1B, the cleaning medium rectifying unit 6 is disposed on the path where the cleaning medium 8 accelerated by the cleaning medium accelerating unit 4 reaches the cleaning target 9 via the cleaning tank 2. Control is performed so that the flow direction of the cleaning medium 8 is aligned so that the installed and accelerated cleaning medium 8 does not fly out of the range of the object 9 to be cleaned. However, a gap is provided between the cleaning medium accelerating unit 4 and the cleaning medium rectifying unit 6 to such an extent that the cleaning medium 8 conveyed from the circulation unit 3 does not hinder the entry. Since the cleaning medium rectifying unit 6 covers the path from the cleaning medium accelerating unit 4 to the object 9 to be cleaned, the cleaning medium rectifying unit 6 is not obstructed by the turbulent airflow generated by the circulation unit 3 and the cleaning medium regenerating unit 5. Moreover, when using the workpiece holder etc. which hold | maintain the washing | cleaning target object 9, you may install the washing | cleaning medium rectification | straightening means 6 in a workpiece holder etc. Note that the rectification of the cleaning medium 8 by the cleaning medium rectifying means 6 means that the flow direction of the cleaning medium 8 is made uniform.

  As the configuration of the cleaning medium rectifying unit 6, for example, as shown in FIG. 3, the wall surface of the cleaning medium rectifying unit 6 may be formed in a concave curved surface along the flow direction. By forming in this way, the high-speed airflow from the cleaning medium accelerating means 4 is prevented from diffusing, the cleaning medium 8 is prevented from escaping from the cleaning medium rectifying means 6, and a large amount of the cleaning medium 8 is efficiently conveyed. Thus, the cleaning efficiency can be increased.

  Moreover, as shown in FIG. 4, you may provide the groove | channel formed in the wall surface of the washing | cleaning medium rectification | straightening means 6 by the some square shape or curved surface along the flow direction. The width of the groove is made smaller than the surface size of the cleaning medium 8 so that the cleaning medium 8 does not fall into the groove. By providing the groove in this way, a space can be formed between the wall surface of the cleaning medium rectifying means 6 and the cleaning medium 8 to reduce the contact resistance between the wall surface and the cleaning medium 8, and the airflow is generated in the groove. By flowing, the cleaning medium 8 can be efficiently conveyed and a large amount of the cleaning medium 8 can be conveyed. In addition, the air flow rectification effect is added by the plurality of grooves, the turbulent flow is less likely to occur, the force of the air flow is less likely to be attenuated, and the cleaning medium 8 can be efficiently transported and flying, thereby further improving the cleaning efficiency. Can do. Further, the contact area between the wall surface and the cleaning medium 8 is reduced by the groove, and the cleaning medium 8 is difficult to stick to the wall surface, and the cleaning medium 8 can be efficiently transported and flying, thereby further improving the cleaning efficiency. be able to. The height of the groove only needs to allow airflow to pass. For example, if the height is about 0.1 mm to 1 mm, the groove can be easily processed.

  Further, as shown in FIG. 5, the cleaning medium rectifying means 6 may be provided with a static eliminating means 61. The neutralization means 61 is for removing the electric charge charged in the cleaning medium 8, and an ionizer using corona discharge by the discharge needle 62 and a neutralization brush on the wall surface of the cleaning medium rectification means 6 to form self-discharge and ground leakage. Is used. By neutralizing the cleaning medium 8 in this manner, the cleaning medium 8 is prevented from being electrostatically adsorbed to the wall surface of the cleaning medium rectifying means 6, and the cleaning medium 8 is difficult to stick to the wall surface. Can be transported and allowed to fly, and the cleaning efficiency can be further improved.

[Device operation]
Next, the dry cleaning operation by the dry cleaning apparatus will be described.
(1). In FIG. 1, with the flaky cleaning medium 8 charged in the cleaning tank 2, the cleaning object 9 held by the work holding means is input from the cleaning object input port of the cleaning tank 2 and initially. The cleaning object charging port is closed with the cleaning object charging lid and the cleaning tank 2 is sealed.
(2) When the circulation means 3 is operated, the cleaning medium 8 scattered in the cleaning tank 2 in the initial state is carried to the cleaning medium acceleration means 4 along the cleaning tank wall surface as a circulation path.
(3) When the compressed air is supplied to the cleaning medium accelerating means 4, the cleaning medium 8 is accelerated toward the object to be cleaned and flies to the object 9 to be cleaned at a high speed.
(4) The flow direction of the cleaning medium 8 is controlled by the cleaning medium rectifying means 6 so that the cleaning medium 8 accelerated when the cleaning medium 8 flies does not fly out of the range of the object 9 to be cleaned. 8 collides with the object 9 to be cleaned.
(5) When the cleaning medium 8 contacts or collides with the cleaning object 9 at a high speed, the adhering material adhering to the cleaning object 9 is knocked down. The struck dust and the cleaning medium 8 are carried again to the cleaning tank wall surface by the return air flow generated from the cleaning medium acceleration means 4, the circulation means 3 and the cleaning medium regeneration means 5, and then to the cleaning medium regeneration means 5. .
(6) The cleaning medium 8 to which the dust passing through the cleaning medium regenerating means 5 and the adhering matter such as dust adheres is carried by the porous member of the cleaning medium regenerating means 5 on the flow of the air flow toward the dust collector (dust collector) 7. 51 is attracted (FIG. 2). Here, the dust passes through the porous member 51 and is discharged from the cleaning tank 2, and the deposits attached to the cleaning medium 8 are also separated from the cleaning medium 8 and discharged from the cleaning tank 2.
(7) The cleaning medium 8 that has passed through the cleaning medium regeneration means 5 is conveyed again to the cleaning medium acceleration means 4 by the circulation means 3.

By repeating the operations (1) to (7), the deposits can be effectively removed from the object 9 to be cleaned while circulating the cleaning medium 8 in the cleaning tank. Further, according to this configuration, even if the dust is relatively strong and difficult to remove by air blow alone, the cleaning medium 8 flying at high speed can be separated from the object to be cleaned 9 by contact and collision. it can. In particular, when the lamellar cleaning medium 8 is used, a higher cleaning quality and cleaning efficiency can be obtained, and an excellent effect of not damaging the cleaning target 9 is exhibited. Further, the dust adhering to the cleaning medium 8 is effectively removed by the cleaning medium regenerating means 5, and the cleanliness of the cleaning medium 8 is always maintained. High cleaning quality is obtained without re-adhering to 9.
Further, by giving the workpiece holding means (not shown) a posture movement function having a plurality of movement axes, by repeatedly performing the operations (1) to (7) while changing the posture of the object 9 to be cleaned, High cleaning quality can be obtained without uneven cleaning.

  Next, a second embodiment of the present invention will be described.

[Cleaning medium acceleration means]
In the second embodiment of the present invention, in order to make the cleaning medium 8 always collide with the object 9 to be cleaned through the cleaning medium rectifying means 6, as shown in FIG. 6, the compressed air of the cleaning medium accelerating means 4 is used. Are ejected from the acceleration nozzle along the cleaning medium rectifying means 6.

[Cleaning medium rectification means]
The cleaning medium rectifying unit 6 causes the cleaning medium 8 to collide with the object to be cleaned 9 without decelerating after all the cleaning media 8 accelerated by the cleaning medium accelerating unit 4 collide with the wall surface of the cleaning medium rectifying unit 6. Guided. In this configuration, since almost all of the cleaning medium 8 is concentrated in a limited range near the wall surface of the cleaning medium rectifying means 6, the cleaning surface of the cleaning object 9 is also limited to this range, but the cleaning is very high. Quality is obtained.
Therefore, as shown in FIG. 6, it is preferable to have a movable means 10 having several moving shafts that can change the orientation of the wall surface of the cleaning medium rectifying means 6. By doing so, cleaning unevenness is eliminated and high cleaning quality is obtained.
Further, since the cleaning medium rectifying means 6 can fly the cleaning medium 8 at an angle where it is difficult for the single cleaning medium accelerating means 4 to collide with the cleaning medium rectifying means 4, the cleaning target 9 having a complicated shape is free from uneven cleaning. Cleaning quality is obtained.
Other apparatus configurations and operations are the same as those in the first embodiment.

  Next, a third embodiment of the present invention will be described.

[Cleaning medium rectification means]
In the third embodiment of the present invention, the cleaning medium attitude control means for correcting the attitude of the cleaning medium 8 when the cleaning medium 8 passes through the cleaning medium rectifying means 6 is adopted. As an example, in the dry cleaning apparatus 1 having the configuration shown in FIG. 1 or FIG. 6, the cleaning medium posture control means 11 is located near the wall surface of the cleaning medium rectifying means 6 as shown in FIGS. It consists of an obstacle in the form of a wire or taper (wedge shape) that is installed, and this wire-like or taper (wedge shape) cleaning medium rectifier 6 forcibly rotates the cleaning medium 8 flying in a plane. To change the posture.
As a result, the posture of the cleaning medium 8 that collides with the object 9 to be cleaned can collide with the edge instead of the plane of the cleaning medium 8. Therefore, the collision energy of all the cleaning media 8 can be concentrated on the edge, and the removal capability is improved and high cleaning quality is obtained. Further, even if the groove is smaller than the cleaning medium size existing in the cleaning object 9, the edge of the cleaning medium 8 can be aligned toward the groove, so that the groove can be easily penetrated and attached to the groove. Deposits can be removed.
Other apparatus configurations and operations are the same as those in the first or second embodiment.

  In office equipment such as copiers, facsimiles, and printers, used products or units (process cartridges, development units, cleaning units, various other units, etc.) are collected from the user, disassembled, cleaned, reassembled, and reassembled as parts. It can be used or used as a resin material, but in order to reuse the parts used in these products or units, the fine particles (toner, paper powder, A process for removing and cleaning dust, dust, etc. is necessary.

  Therefore, the present invention is shown in Examples 1 to 3 in order to remove and clean the fine particle powder (toner, paper powder, dust, dust, etc.) adhering to the cleaning object such as the above-mentioned units and parts. Cleaning is performed by a cleaning method using the dry cleaning apparatus 1. As a result, the washed items such as the above-described units and parts can be reliably washed and reused stably.
