Abstract

PROBLEM TO BE SOLVED: To sufficiently generate a brushing effect by a magnetic washing medium even against a local part becoming a blind alley by controlling a motion of the magnetic washing medium corresponding to a contaminated part in a tonner cartridge and a process cartridge and to enhance a washing effect by the magnetic washing medium while preventing a scattering of the tonner to a working environment. SOLUTION: In the washing method, a magnetic material is used as a washing medium and an inner wall surface of an object to be washed is washed by a magnetic field caused by a leak magnetic flux. The washing is carried out while a rotation and a non-rotation of a rotary leak magnetic flux generator for generating the leak magnetic flux are switched to each other. The magnetic washing medium is rotated in the state that it is pressed to the inside of the object to be washed by an alternating variation caused by a rotation of the magnetic field accompanying with a rotation of the rotary leak magnetic flux generator. The rotation or stopping of the rotation is repeated. Thereby, contaminants in the object to be washed are adsorbed/retained to the magnetic washing medium. Corners of the object to be washed are collectively washed by colliding or rubbing the magnetic washing medium on an inner surface of the object to be washed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal cleaning technique for the purpose of recycling (reusing) a container (eg, toner cartridge) of an engine section of a copying machine or a laser printer. The remaining residue can be cleaned up to every corner very efficiently and efficiently. It is possible to clean the inside of general plastic molded products or use ordinary cleaning tools such as brushes and sponges such as return bottles. It can be effectively used for cleaning a container having a shape in which it is difficult to clean all corners.

[0002]

2. Description of the Related Art In order to make it possible to efficiently and effectively clean various parts of an engine section of a copying machine or a laser printer for reuse, devise a structural design such as a disassembly structure, or The current situation is to devise a cleaning method such as suctioning and cleaning with air vacuum. Since this cleaning method by suctioning is not a method of cleaning while rubbing the inner surface and the outer surface of the container, it is difficult to completely clean the toner electrostatically adsorbed on the inner surface and the outer surface. In addition, the cleaning actually performed by the toner refilling company is ultrasonic cleaning or vacuum cleaning, but this cleaning method can also be used to efficiently and efficiently remove and clean the toner adhering to the inner surface of the container. I can't. Besides, although not known, as prior art,
An internal cleaning method for cleaning and removing the toner adhering to the container using a magnetic material is described in the specification of Japanese Patent Application No. 2000-083638, and a method for cleaning a toner cartridge using a toner carrier is also specified. Wish 2001-06
6637.

By the way, in recent years, awareness of global environment protection has increased, and used electronic equipment products, household electric appliances, and office equipment are not discarded as in the past, but are sorted by resource type and reused for each resource, Parts that have been used once are being reused. Various equipment products are disassembled into parts, and it is recommended that the disassembled parts be washed and reused.
Being promoted. In an image forming apparatus using an electrophotographic technique, toner is used as a developing material for forming an image. In many cases, this toner agglomerates in the storage container due to aging, adheres to the toner case, and is not removed by simple cleaning. For this reason, after disassembling the developing unit, the case is cleaned by rubbing the sticky toner with a brush, and the parts that are out of reach are cleaned manually by a method such as high-pressure jet water flow or steam. Is the reality. However, when the toner case has a perfect dead end shape, it is very difficult to clean the inside of the toner case. In addition, since many types of products collected on the market are mixed and their shapes are different, it is common to wash each one by hand, and it takes a lot of time for the washing process. It takes labor and cost. Further, since this cleaning work is a work environment in which toner dust is generated, there is a problem that the work environment maintenance cost such as attaching a toner exhaust device to prevent the worker from inhaling the toner increases the work environment. Since the cleaning work is performed manually, the cleaning accuracy varies. In order to solve these problems, it is desired to completely automate the cleaning work.

As an internal cleaning method using a magnetic material, there is a cleaning method of Japanese Patent Application No. 2000-083638. But,
Since the cleaning by this method is only the sweeping effect by the lateral movement of the magnetic material, the sweeping effect of the toner adhering to the inner surface of the object to be cleaned can be expected, but it is concentrated on the inner surface locally. There is a problem that the effect of scraping off the existing toner (contaminant) is weak, and therefore there is a high possibility that cleaning failure will occur with respect to the contaminant that is locally and intensively adhered. Also, in the cleaning method of Japanese Patent Application No. 2001-066637, it is necessary in principle to apply sufficient friction to the toner carrier to charge it, but in the conventional method, since the stirring ability is weak, it is necessary to sufficiently charge the toner carrier. There is a problem that it takes a long time.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention controls the movement of a magnetic cleaning medium corresponding to a dirty portion inside a toner cartridge or a process cartridge to form a dead end. In view of the above, the first problem is to sufficiently generate the brush effect by the magnetic cleaning medium and improve the cleaning effect by the magnetic cleaning medium while preventing the toner from scattering into the working environment. In addition, regarding the problem of variation in cleaning accuracy that is inherent in the prior art, it is possible to stabilize cleaning quality by automation and to deal with a wide variety of collected products by using a three-dimensional database.
Is the subject of. In addition, Coulomb force, van der Waals force, or other adsorption force can be used to clean objects other than powder such as toner and paper powder, and improve the cleaning speed for contaminants adhering to the inner surface. Is the third issue.

[0006]

[Measures taken to solve the problem]

SOLUTION 1 (corresponding to claim 1) A solution means 1 for solving the above-mentioned problems is to use a magnetic material as a cleaning medium in a cleaning method for cleaning an inner wall surface of an object to be cleaned by a magnetic field caused by a leakage magnetic flux. Cleaning is performed by switching between rotation and non-rotation of the rotary leakage flux generator that generates leakage flux.

[Function] The magnetic cleaning medium is rotated while the magnetic cleaning medium is pressed against the inside of the object to be cleaned by the alternating change due to the rotation of the magnetic field accompanying the rotation of the rotary leakage magnetic flux generator, or the rotation is stopped to repeat the cleaning. The contaminants in the body are adsorbed and held by the magnetic cleaning medium, and the magnetic cleaning medium collides against or rubs against the inner surface of the object to be cleaned, whereby the cleaning target is thoroughly cleaned in every corner.

[0007]

SOLUTION 2 (corresponding to claim 2) The solution means 2 is to move a rotary leakage flux generator for generating leakage flux in the solution means 1 in the lateral direction to wash it.

The magnetic cleaning medium repeatedly collides with and scatters on the inner surface of the object to be cleaned due to the alternating change due to the rotation of the magnetic field by the rotary leakage magnetic flux generator and the lateral movement of the entire magnetic field, and also the inner surface of the object to be cleaned. Since it is dragged while being strongly pressed against, the contaminants adhering to the inner surface of the object to be cleaned can be effectively cleaned by the magnetic cleaning medium.

[0008]

SOLUTION: The solving means 3 (corresponding to claim 3) sets a moving path of a rotary leakage flux generator for generating leakage flux based on three-dimensional data of an object to be cleaned. Is.

[Operation] The motion of the rotary leakage magnetic field generation mechanism is controlled by the object to be cleaned 3
Since it is performed based on the dimension data, it is possible to move the rotary leakage magnetic field generation mechanism along the outer shape of the object to be cleaned, and by doing so, by registering the database for various objects to be cleaned, Objects to be cleaned can be automatically cleaned by moving them along the most effective path of the rotary leakage magnetic field generation mechanism.

[0009]

SOLUTION 4 (corresponding to claim 4) In a solution means 4, in the solution means 1 to the solution means 3, the magnet arrangement of the rotary leakage magnetic flux generator has a singular point due to a rotation center due to revolution and rotation. It is something that has been lost. The “singular point” means a region where the magnetic cleaning medium hardly moves due to the rotation of the rotary leakage magnetic flux generator.

Since the rotary leakage magnetic flux generator revolves around its own axis, the singularity of the rotary leakage magnetic flux generator when it rotates only is eliminated by the revolution. Therefore, there is no portion inside the article to be cleaned where the cleaning action of the magnetic cleaning medium does not reach, and therefore the inner surface of the article to be cleaned is evenly cleaned.

[0010]

SOLUTION 5 (corresponding to claim 5) Solution means 5 controls the motion state of a magnetic material, which is a cleaning medium, by controlling the rotation speed of a rotary leakage magnetic flux generator in solution means 1 to 4. That is, the adsorption and sweep operations are used separately.

[Operation] By controlling the motion state of the magnetic material as the cleaning medium by controlling the rotation speed of the rotary leakage magnetic flux generator, the motion pattern can be selectively used for diffusion and aggregation according to the cleaning condition, and cleaning and sweeping by adsorption. Each effect of cleaning by can be utilized.

[0011]

SOLUTION 6 (corresponding to claim 6) Solution means 6 is provided with two or more rotary leakage flux generators in solution means 1 to 5, and independent rotation speed control is performed based on a cleaning sequence. Is made possible.

The magnetic field can be applied to the entire outer wall of the object to be cleaned by each of the two rotating leakage magnetic field generating mechanisms, and a plurality of magnetic field forming magnetic circuits are formed. And
Since the two rotary leakage magnetic field generation mechanisms can independently control the movement and rotation, by changing each of the above movement and rotation depending on the cleaning site, the movement and rotation can effectively play the role of aggregation and diffusion. It can be shared efficiently.

[0012]

SOLUTION MEANS (Corresponding to Claim 7) The solution means 7 is to make the posture of the object to be cleaned programmable in the solution means 6.

The magnetic field can be applied to the entire outer wall of the object to be cleaned by each of the two rotating leakage magnetic field generating mechanisms. By confirming the respective rotation speeds of the two rotating leakage magnetic field generation mechanisms that change the motion mode in advance, and switching their cleaning characteristics (coagulation is a sweeping effect, diffusion is an adsorption effect), a cleaning program is created. By executing this, the inside of the object to be cleaned can be efficiently and stably cleaned.

[0013]

SOLUTION 8 (Corresponding to Claim 8) Solution 8 is that, in Solution 1 to Solution 7, a magnetic material has its surface coated with a physical adsorption layer other than magnetic force.

[Function] Since the magnetic cleaning material used is a physical adsorption layer other than magnetic force that has been surface-treated, contaminants floating in the body to be cleaned are adsorbed and captured by the physical adsorption layer of the magnetic cleaning material. The cleaning of the object to be cleaned is effectively and efficiently performed.

[0014]

SOLUTION 9 (corresponding to claim 9) As a solution, the solution 9 is a solution in which water, a surfactant or the like (diluted or undiluted) is mixed with a magnetic material. It is to be.

The magnetic body is agitated in association with the rotation of the rotary leakage magnetic field generation mechanism. This stirring action produces a water flow in the direction of rotation. Further, the magnetic body is interlocked in the same direction by linearly moving the rotary leakage magnetic field generation mechanism to scan the outer wall of the object to be cleaned. Due to the movement of these magnetic bodies, contaminants adhering to the inner surface of the object to be cleaned are scraped off and the scraped contaminants diffuse into the cleaning liquid, so that the inner wall of the object to be cleaned is cleaned.

[0015]

Solving means 10 (corresponding to claim 10) Solving means 10
In the solution means 1 to 9, the magnetic material has a soft magnetic property.

Since the magnetic cleaning medium injected into the object to be cleaned has soft magnetic properties, even if the magnetic circuit of the rotary leakage magnetic field generation mechanism rotates and an alternating magnetic field is apparently applied. The force F for pressing the magnetic cleaning medium against the wall surface of the object to be cleaned hardly changes, and the wall surface is scratched with a strong force only by the flow of the magnetic cleaning medium due to the accompanying movement due to the rotation of the rotary leakage magnetic field generating mechanism. It can be dropped and washed with this scraping effect.

[0016]

Solving means 11 (corresponding to claim 11) Solving means 11
In the solution means 1 to 10, the magnetic characteristics of the magnetic material are hard magnetic characteristics.

Since the magnetic cleaning medium is a hard magnetic material, when the magnetic circuit of the rotary leakage magnetic field generating mechanism is rotated and an apparent alternating magnetic field is applied to the magnetic cleaning medium, the magnetic cleaning medium becomes a hard magnetic material. Due to the characteristics (itself is a magnet and has polarity), repulsion and attraction are alternately repeated on an alternating magnetic field in which the N pole and S pole are reversed, causing collision and scattering of the object to be cleaned with the wall surface. Repeat and exercise very hard. Due to this vigorous movement, the magnetic cleaning media cause friction with each other and are triboelectrically charged, so that suspended contaminants can be adsorbed by Coulomb force. Therefore, every part of the magnetic cleaning medium is uniformly cleaned by vigorous motion of the magnetic cleaning medium in the object to be cleaned.

[0017]

Solving means 12 (corresponding to claim 12) solving means 12
In the solution means 9, an abrasive is mixed in the cleaning liquid.

When the magnetic substance is agitated by the rotary leakage magnetic field generating mechanism, a water flow is generated inside the magnetic substance. By this water flow, the polishing agent repeatedly collides with the wall surface of the object to be cleaned, and the contaminants attached to the wall surface can be cleaned. Further, the rotary leakage magnetic field generating mechanism is caused to scan along the outer wall of the object to be cleaned, and the magnetic cleaning material is interlocked in the same direction to scrape off contaminants adhering to the object to be cleaned. As a result, the inner wall of the object to be cleaned is thoroughly cleaned, and the contaminants diffuse into the cleaning liquid.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments will be described with reference to the drawings. [Specific Example of Solving Means 1] FIG. 1 schematically shows an outline of a configuration corresponding to the solving means 1. The article to be cleaned 1 is a container with a bottom and a small mouth, such as a toner cartridge of a copying machine or a laser printer, or a returnable bottle. Since the object to be cleaned 1 has a small mouth, even if a cleaning instrument is inserted through this mouth, the entire surface of the inner wall cannot be rubbed with the cleaning instrument. It is not possible to wash and remove the contaminants. In this embodiment, a powdery or granular magnetic cleaning medium 2 is injected into the object to be cleaned 1. Since the object to be cleaned 1 is placed on the rotary stray magnetic field generating mechanism 3 including the contact plate 5, the magnetic circuit 6, and the motor 4, the magnetic cleaning medium 2 is generated from the rotary stray magnetic field generating mechanism 3. It is constrained by the magnetic field and is pressed against the inner wall surface of the object to be cleaned 1 by the magnetic attraction force F on the lower inner surface of the object to be cleaned 1. This pressing force F and the rotational kinetic energy of the leakage magnetic field generated by the rotation of the magnetic circuit 6 of the rotary leakage magnetic field generation mechanism 3 cause the magnetic cleaning medium 2 to rotate in conjunction with each other. The swirling motion of the magnetic cleaning medium 2 along the inner surface of the object to be cleaned 1 rubs the powder (contaminant) adhering to the inner wall surface of the object to be cleaned 1 to separate it. Further, when the rotation speed of the magnetic circuit 6 of the rotary leakage magnetic field generation mechanism 3 reaches a certain value, the centrifugal force due to the rotation overcomes the pressing force F, so that the magnetic washing medium 2 is scattered by the centrifugal force and The magnetic cleaning medium 2 adsorbs the powder suspended in the magnetic powder and can clean it.

[Specific Example of Solving Means 2] FIG. 2 schematically shows the principle of the sweeping action in the case of cleaning by moving (rotating type) leakage magnetic flux generator for generating a leakage magnetic flux (Solution 2). . For simplicity, FIG. 2 shows a magnet 3a that does not rotate as a leakage magnetic flux generator, but the principle of operation is the same even if the rotary leakage magnetic field generating mechanism 3 is linearly moved. As shown in FIG. 2, the contaminants 15 diffused and accumulated on the wall surface can be moved laterally like sweeping with a broom. Of course, even in such a state, the magnetic cleaning medium 2 moves the inner wall of the object to be cleaned 1 by moving the rotary leakage magnetic field generating mechanism 3 back and forth and left and right.
It also has a function of scraping contaminants stuck to the inner wall by rubbing it while being pressed by the force F. Also, as is
However, if you move it laterally (left and right), you can clean the entire inner wall.

[Specific Example of Solving Means 3] The three-dimensional shape data of the article to be cleaned 1 shown in FIG. 3 is preliminarily made into a library as a database in the computer 8 or is taken in from another database by the LAN 9. Has become. The computer 8 containing the main routine program of the robot takes in the data of the database and automatically generates the program, or loads the pre-libraryized program,
The rotary leakage magnetic field generation mechanism 3 is moved in the arrow direction along the outer shape of the object to be cleaned 1. Thus, by registering the databases of various items to be cleaned 1, it is possible to automatically clean the items to be cleaned 1 of various kinds.

[Specific Example of Solving Means 4] The rotary leakage magnetic flux generating mechanism shown in FIG. 4 has a magnetic circuit 6 and a rotation motor 4.
a, the revolution plate 4c, and the revolution motor 4b. If the rotation motor 4a is rotated and the magnetic circuit 6 is rotated by this, a rotational leakage magnetic field is formed on the rotation locus 11. However, in this case, no matter what shape the magnetic circuit 6 has, the center of rotation is a region (singular point) in which the magnetic cleaning medium 2 does not flow, and the rubbing effect does not occur only in that region, so this region is Not washed. Therefore, by rotating the revolution motor 4b and moving the singular point along the revolution locus 10, the singular point is eliminated and uniform cleaning is possible.

[Specific Example of Solving Means 5] In the one shown in FIG. 5, two rotary leakage magnetic field generating mechanisms 3A and 3B are arranged on the left and right of the object to be cleaned 1 and the rotational speed of the magnetic circuit 6 is made variable. It is a constituent. This is because the motion characteristics of the magnetic cleaning medium 2 differ depending on the rotation speed. The rotary leakage magnetic field generation mechanism 3A rotates at a rotation speed of about 500 rpm or more. At this time, the rotary leakage magnetic field generation mechanism 3
The magnetic cleaning medium 2 interlocked with the rotation of A is repelled by the centrifugal force over its adsorption force F, and diffuses inside the object to be cleaned 1. As the magnetic cleaning medium 2 diffuses, the magnetic cleaning medium 2 is evenly charged by friction, and evenly contacts and adsorbs the contaminants attached to the inner wall surface of the object to be cleaned 1. The rotating leakage magnetic field generating mechanism 3B in FIG. 5 rotates at a lower speed than the rotating leakage magnetic field generating mechanism 3B. Therefore, the magnetic cleaning medium 2 attracted to the rotary leakage magnetic field generation mechanism 3B does not diffuse, and the magnetic cleaning medium 2 is attracted to the rotary leakage magnetic field generation mechanism 3B and aggregates. In this state, when the rotary leakage magnetic field generating mechanism 3B moves in the vertical direction shown by the arrow, the sweeping effect by the magnetic cleaning medium 2 is obtained. By doing so, there is a difference in the cleaning mode depending on the motion characteristics of the magnetic cleaning medium 2 by the left and right rotary leakage magnetic field generation mechanisms 3A and 3B. Therefore, the left and right rotary leakage magnetic field generation mechanisms 3A and 3B are controlled while controlling the rotation speed. By moving, it is possible to utilize the sweeping effect and the adsorption effect, and it is possible to obtain a higher quality cleaning result. The rotation speed in each motion mode depends on the leakage magnetic flux density, the surface roughness of the object to be cleaned 1, the radius of the magnetic circuit 6, the magnetic characteristics of the magnetic cleaning medium 2 and the like, and therefore is not unconditionally specified. However, since the cleaning modes differ due to the difference in the motion mode and the correlation can be grasped, it is easy to find the rotation speed suitable for ensuring the predetermined cleaning effect. In this example, the outer diameter of the magnetic circuit 6 is 50 mm,
The magnetic force is 2k Gauss, but in this case, the rotation speed is 500.
˜800 rpm and revolution speed 5˜30 rpm.

[Specific Examples of Solving Means 6 and 7] FIG.
In the example shown in (2), two rotary leakage magnetic field generation mechanisms 3 whose rotation speeds can be controlled are arranged on the left and right of the article to be cleaned 1, and the slide mechanisms 18 support the two so as to be vertically slidable. . The item to be cleaned 1 is a yaw motor 1.
It is rotatably supported by a rotary drive mechanism driven by 6. This rotation drive mechanism can rotate the object to be cleaned 1 in the yaw direction (arrow direction) by a maximum of 360 ° by the yaw motor 16. Further, another motor (not shown) can rotate the entire pitch in the direction of the arrow indicated by reference numeral 17. The pitch rotation range can be 360 °. In the above system, the rotating leakage magnetic field generating mechanisms 3 and 3 can apply a magnetic field over the entire outer wall of the article to be cleaned 1. A cleaning program is created by confirming the rotation speeds of the rotating leakage magnetic field generating mechanisms 3 and 3 whose motion modes change in this system in advance and switching their cleaning characteristics (sweep effect for coagulation, adsorption effect for diffusion). Then, by executing this, the inside of the object to be cleaned 1 can be efficiently and stably cleaned. For example, the magnetic cleaning medium 2 diffused by first adsorbing contaminants to the magnetic cleaning medium 2 and then diffusing.
If the particles are aggregated and then collected from the discharge port 19 by the sweeping effect, the cleaning work can be performed efficiently.

[Specific Example of Solving Means 8] The magnetic cleaning medium 2 shown in FIG. 7 has a particle diameter of about 0.1 mm or less, and the magnetic body 12 inside is covered with a surface layer 13.
In FIG. 7A, the surface layer 13 is a dielectric layer having a large charge capacity, such as silicon, and the surface layer 13 shown in FIG.
The one shown in Figure 1 has whiskers on its outer surface. The surface layer 13 may be coated with a gel-like adhesive substance such as an acrylic adhesive or a rubber adhesive. Since the inside of the magnetic cleaning medium 2 is the magnetic substance 12, it can be operated (or driven) by its magnetic force by the magnetic field generator, and the dielectric layer of the surface layer 13 electrostatically adsorbs contaminants by Coulomb force. To do. The whisker-shaped whiskers shown in FIG. 7B adsorb and hold contaminants due to van der Waals force due to the large surface area and entanglement of the whiskers.

[Specific Example of Solving Means 9] The cleaning liquid 14 injected into the object to be cleaned 1 shown in FIG. 8 is used for general cleaning such as water or a surfactant. A magnetic material 12 similar to the magnetic material 12 in FIG.
Is mixed in. The magnetic body 12 is agitated in association with the rotation of the rotary leakage magnetic field generation mechanism 3. This stirring action produces a water flow in the direction of rotation. Further, the magnetic substance 12 is interlocked in the same direction by scanning the outer wall of the object to be cleaned 1 by rotating the rotary leakage magnetic field generating mechanism 3 in the direction of the linear arrow shown in the figure. By the movement of these magnetic bodies 12, the object to be cleaned 1
The contaminants adhering to the inner surface are scraped off, and the scraped contaminants diffuse into the cleaning liquid 14, so that the inner wall of the object to be cleaned 1 is cleaned. Thereafter, the cleaning liquid 14 is discharged, rinsed, and dried to complete the cleaning of the inside.

[Specific Example of Solving Means 10] The magnetic cleaning medium 2 injected into the object to be cleaned 1 shown in FIG. 9 is, for example, a soft iron material having a soft magnetic property. Therefore, even if the magnetic circuit 6 of the rotary leakage magnetic field generation mechanism 3 rotates and an apparent alternating magnetic field is applied, the force F for pressing the magnetic cleaning medium 2 against the wall surface of the object to be cleaned 1 hardly changes, and moreover, The wall surface can be scraped off with a strong force only by the flow of the magnetic cleaning medium 2 due to the accompanying movement due to the rotation of the rotary leakage magnetic field generating mechanism 3, and the effect can be cleaned. This method is more effective when there is much dirt adhering to the wall surface.

[Specific Example of Solving Means 11] The magnetic cleaning medium 2 shown in FIG. 10 is, for example, an austenitic SU.
It is a hard magnetic material such as S material. The magnetic circuit 6 of the rotary leakage magnetic field generating mechanism 3 rotates and applies an apparent alternating magnetic field to this material. Then, the magnetic cleaning medium 2 has a characteristic as a hard magnetic material, that is, a characteristic that it is a magnet itself and has a polarity. Therefore, repulsion and attraction are alternately repeated on an alternating magnetic field in which the N pole and the S pole are reversed. Then, it collides with the wall surface of the object to be cleaned 1 and repeatedly flies, and moves extremely violently. Due to this vigorous exercise, the magnetic cleaning medium 2
Rub against each other and are triboelectrically charged, so suspended contaminants can be adsorbed by Coulomb force. therefore,
Due to the violent movement of the magnetic cleaning medium 2 in the object to be cleaned 1, all the corners thereof are cleaned evenly. The medium is rotated and attracted for a certain period of time, and then the rotation is stopped and the medium is moved without reversing the polarity, and the medium is ejected by the sweeping effect. This method is suitable for cleaning even if the pollutant (powder etc.) does not adhere so much and the contaminated area is wide.

[Specific Example of Solving Means 12] The cleaning liquid 14 shown in FIG. 11 is used for general cleaning such as water or a surfactant. The magnetic substance 12 and the abrasive 15 are mixed in the cleaning liquid 14. When the magnetic substance 12 is agitated by the rotary leakage magnetic field generation mechanism 3, a water flow is generated inside the magnetic substance 12. The abrasive 15 repeatedly collides with the wall surface of the object to be cleaned 1 by this water flow, and cleans the contaminants adhering to the wall surface.
Further, as shown in the drawing, the rotary leakage magnetic field generating mechanism 3 is scanned along the outer wall of the object to be cleaned 1 and the magnetic substance 12 is interlocked in the same direction to scrape off the contaminants attached to the object to be cleaned 1. . As a result, the inner wall of the object to be cleaned 1 is thoroughly cleaned, and the contaminants diffuse into the cleaning liquid 14. Thereafter, the cleaning liquid 14 is discharged, rinsed, and dried to complete the cleaning of the inside.
