It is a front view of the cleaning tool by 1st Embodiment of this invention. It is the figure seen from the II-II line shown in FIG. It is the figure seen from the III-III line shown in FIG. It is a figure which shows the internal structure of the cleaning tool shown in FIG. 1, Comprising: It corresponds to FIG. It is an expanded sectional view of the VV line shown in FIG. It is a schematic sectional drawing which shows the 1st process of attaching a grinding | polishing body to the drive shaft in the cleaning tool shown in FIG. It is a schematic sectional drawing which shows the 2nd process of attaching a grinding | polishing body to the drive shaft in the cleaning tool shown in FIG. It is a schematic sectional drawing which shows the 3rd process of attaching a grinding | polishing body to the drive shaft in the cleaning tool shown in FIG. It is a schematic sectional drawing of the cleaning tool of the state pressed against the top plate of the electromagnetic cooking device, Comprising: It is the figure which compared embodiment of this application and a prior art example. It is a perspective view which shows the conventional cleaning tool.

  FIG. 1 is a front view of a cleaning tool according to a first embodiment of the present invention, FIG. 2 is a view taken along line II-II shown in FIG. 1, and FIG. FIG. 4 is a view as seen from line III, and FIG. 4 is a view showing the internal structure of the cleaning tool shown in FIG. 1 and corresponds to FIG.

  With reference to these drawings, the cleaning tool 1 includes a grip body 10 made of an ABS resin mainly containing acrylonitrile, butadiene, and styrene, and a front surface of the grip body 10. It is mainly composed of a spherical crown-shaped polishing body 20 detachably attached to the side (left side in FIG. 2). The effect of the shape of the polishing body 20 will be described later.

  The gripping body 10 includes a body portion 11, a front surface portion 12 that is detachably attached to a front side end portion of the body portion 11, and a bottom portion 13 that is detachably attached to a lower end of the body portion 11. . Further, a part of the front side of the body part 11 and a part of the back side (right side in FIG. 2) are covered with elastic bodies 14a and 14b made of elastomer or the like, and the elastic body 14b on the back side is covered. Is formed with a protrusion 15. Thus, since a part of the holding body 10 is covered with the elastic bodies 14a and 14b, the feeling of use when the holding body 10 is held in the hand is improved.

  As shown in FIG. 4, the gripping body 10 stores a motor 31 that is a driving mechanism and a speed reducer 32 connected to the motor 31. And the drive shaft 36 of the reduction gear 32 is formed so that it may protrude outward via the front surface part 12 of the holding body 10.

  In addition, it is preferable to set the rotation speed of the drive shaft 36 output from the motor 31 via the reduction gear 32 to 100 to 300 rpm when there is no load. When the rotational speed of the drive shaft 36 is less than 100 rpm, the effect of removing dirt decreases. Further, if the rotational speed of the drive shaft is larger than 300 rpm, for example, when the user's hair is entangled, the hair may continue to be wound, which is problematic from the viewpoint of safety. Furthermore, it is more preferable to set the speed to 150 to 250 rpm when no load is applied because the effect of removing dirt increases.

  The torque of the drive shaft 36 output from the motor 31 via the speed reducer 32 is preferably set to 2.0 to 5.0 kg · cm. When the torque of the drive shaft 36 is set to less than 2.0 kg · cm, the effect of removing dirt decreases. If the torque of the drive shaft 36 is set to be larger than 5.0 kg · cm, it is dangerous because the rotation of the drive shaft 36 cannot be stopped in an unexpected situation.

  Further, a plurality of batteries 33 are stored below the gripping body 10. The battery 33 is connected to the motor 31 by wiring or the like (not shown) so that electric power can be supplied to the motor 31. And since the bottom part 13 of the holding body 10 is attached to the trunk | drum 11 so that attachment or detachment is possible, each battery 33 is easily taken out by removing the bottom part 13 from the trunk | drum 11, as shown by the dashed-two dotted line of a figure. I can do it.

  Further, a switch 34 is housed on the inner side of the protrusion 15 of the elastic body 14b of the gripping body 10. And it is comprised so that the operation | movement of rotation and stop of the motor 31 can be controlled by pressing the switch 34 from the outer side of the projection part 15. FIG.

  The polishing body 20 includes a spherical crown-shaped base 21 attached to the drive shaft 36 of the speed reducer 32, and a disc having a plurality of radial notches 44 formed on the outer edge side thereof. And a polishing pad 40 having a shape. The base 21 of the polishing body 20 is attached to a drive shaft 36 so as to rotate around its central axis. The connecting portion between the base 21 and the drive shaft 36, the detailed structure of the base 21, and the detailed structure of the polishing pad 40 will be described later.

  In such a cleaning tool 1, the polishing body 20 can be operated by operating the motor 31 with the switch 34 while holding the gripping body 10, and the battery 33 is stored in the gripping body 10. A power cord or the like becomes unnecessary. Therefore, the usability of the cleaning tool 1 is improved.

  Here, the connecting portion between the base 21 and the drive shaft 36 of the polishing body 20, the detailed structure of the base 21, and the detailed structure of the polishing pad 40 will be described.

  FIG. 5 is an enlarged cross-sectional view of the VV line shown in FIG.

  Referring to the figure, a base 21 has a disc-shaped bottom plate 22 having an opening 28 formed at the center thereof, a spherical crown-shaped base member 23 attached to the bottom plate 22, and a base member 23 installed on the outer surface of the base member 23. The hook-and-loop fastener 24 and the ring body 25 disposed on the outer surface side of the hook-and-loop fastener 24 are formed so that the inner surface thereof is slightly larger than the outer surface of the end portion of the base member 23.

  A protrusion 29 is formed at the apex portion of the substrate 23. Furthermore, openings 46 and 47 are formed in portions of the hook-and-loop fastener 24 and the polishing pad 40 located on the protrusion 29 in the attached state. Therefore, by disposing the surface fastener 24 and the openings 46 and 47 of the polishing pad 40 on the protrusion 29 of the base material 23, these are placed in a positioning state, so that attachment becomes easy.

  And since the hook_and_loop | surface fastener 24 is comprised so that it may have a stretching property and is attached by the ring body 25 along the outer surface of the base material 23, the hook_and_loop | surface fastener 24 also has a spherical crown shape. A method for attaching the hook-and-loop fastener 24 to the base material 23 by the ring body 25 will be described later.

  The polishing cloth 40 includes a nonwoven fabric 42 disposed on the base 21 side and a polishing layer 41 formed on one surface of the nonwoven fabric 42. The polishing cloth 40 has the same structure as that disclosed in JP-A-2005-66324, and the Mohs hardness of the polishing layer 41 is preferably 1 or more and 4 or less. Such a polishing cloth 40 exhibits a higher removal effect against dirt adhered to the top plate of the electromagnetic cooking device, as compared with a brush or sponge. In a state where the nonwoven fabric 42 of the polishing pad 40 is attached to the base 21, the polishing layer 41 of the polishing pad 40 also has a spherical crown shape. That is, the surface in contact with the dirt in the polishing body 20 has a spherical crown shape.

  Thus, since the nonwoven fabric 42 of the polishing cloth 40 and the surface fastener 24 of the base 21 can be detachably engaged, the polishing layer 41 of the polishing cloth 40 can be easily attached to and detached from the base 21. Furthermore, since the polishing cloth 40 can be easily replaced with the decrease in the polishing layer 41 during continuous use, the cleaning tool 1 can be used efficiently.

  A cylindrical engagement body 37 corresponding to the opening 28 of the bottom plate 22 of the base 21 is connected to the tip of the drive shaft 36 of the speed reducer 32. The bottom plate 22 of the base 21 is detachably connected to the engagement body 37 through the opening 28. At this time, each member is formed so that the center axis of the base material 23 of the base 21 and the drive shaft 36 are aligned.

  Next, a method for attaching the polishing body 20 to the drive shaft 36 will be described.

  6 is a schematic cross-sectional view showing a first step of attaching the abrasive body to the drive shaft in the cleaning tool shown in FIG. 1, and FIG. 7 is a second step of attaching the abrasive body to the drive shaft of the cleaning tool shown in FIG. FIG. 8 is a schematic cross-sectional view showing a third step of attaching a polishing body to the drive shaft in the cleaning tool shown in FIG.

  First, referring to FIG. 6 (1), an engagement body 37 attached to the tip of the drive shaft 36 is inserted into the opening 28 of the bottom plate 22 to which the spherical crown-shaped base material 23 is attached, and these are engaged. Then, the bottom plate 22 is attached to the engagement body 37 of the drive shaft 36. As described above, since each member is configured such that the central axis of the base material 23 and the central axis of the drive shaft 36 are in a straight line, the base material 23 is rotated around the central axis by the drive shaft 36. I can do it.

  Next, referring to (2) of FIG. 6, while extending the flat hook-and-loop fastener 24 on the outer surface of the base material 23 attached to the drive shaft 36 via the bottom plate 22 along the outer surface. Install. At this time, the surface fastener 24 can be easily positioned with respect to the base material 23 by positioning the opening 46 of the surface fastener 24 on the protrusion 29 of the base material 23.

  Next, referring to (1) of FIG. 7, the ring body 25 is placed on the outer side of the hook-and-loop fastener 24 (see FIG. 7) so as to cover the end of the hook-and-loop fastener 24 laid on the outer surface of the base material 23. Attached to the base material 23 from the left side). As described above, since the inner surface of the ring body 25 is formed so as to be slightly larger than the outer surface of the end portion of the base material 23, the ring body 25 smoothly surrounds the base material 23 via the surface fastener 24. It is attached to.

  Next, referring to (2) of FIG. 7, when the ring body 25 is mounted so as to surround the base material 23, the surface fastener is formed by the inner surface of the ring body 25 and the outer surface of the end portion of the base material 23. The end of 24 is sandwiched. That is, the laying state of the hook-and-loop fastener 24 is maintained by these, and is integrated with the base material 23.

  Thereafter, on the outer surface of the hook-and-loop fastener 24, the disc-shaped polishing cloth 40 is aligned with the openings 47 of the polishing pad 40 and the openings 46 of the hook-and-loop fastener 24 so that the nonwoven fabric 42 is in contact with the hook-and-loop fastener 24. Deploy.

  Next, referring to (1) of FIG. 8, as indicated by the arrows in the figure along the outer surface of the hook-and-loop fastener 24 from the state where the hook-and-loop fastener 24 and the central portion of the nonwoven fabric 42 of the polishing pad 40 are engaged. Then, the outer edge portion of the nonwoven fabric 42 of the polishing cloth 40 is engaged with the surface fastener 24. At this time, since the notch 44 as shown in FIG. 1 is formed in the outer edge portion of the polishing pad 40 as described above, the polishing pad 40 can be smoothly attached to the spherical crown-shaped base material 23.

  Next, referring to (2) of FIG. 8, the polishing layer 41 of the polishing pad 40, which is a surface in contact with dirt, is attached along the outer surface of the base material 23, that is, at least the previous portion of the polishing layer 41. When the polishing pad 40 is attached to the hook-and-loop fastener 24 so that the shape becomes a spherical crown, the attachment of the polishing body 20 to the drive shaft 36 is completed.

  Next, the effect of the shape of the polishing body 20 will be described.

  FIG. 9 is a schematic cross-sectional view of the cleaning tool pressed against the top plate of the electromagnetic cooker, wherein (1) shows the cleaning tool shown in FIG. 1, and (2) is a conventional cleaning tool. Is shown.

  First, referring to (1), as described above, the outer surface (surface in contact with dirt) of the polishing cloth 40 disposed on the outer side of the polishing body 20 of the cleaning tool 1 is formed to have a spherical crown shape. ing. When the polishing pad 40 is pressed against the top plate 51 of the electromagnetic cooker, only a part of the outer surface of the polishing pad 40 contacts the top plate 51. That is, since the contact area between the polishing cloth 40 and the top plate 51 is small, the force F for pressing the polishing body 20 against the top plate 51 is concentrated on the contact portion between the polishing cloth 40 and the top plate 51 as shown by the arrows in the figure. To do. Therefore, since the polishing cloth 40 can be intensively pressed against the dirt on the top plate 51, the dirt fixed on the top plate 51 can be easily removed.

  Moreover, in the cleaning tool 1, as above-mentioned, the grinding | polishing body 20 is comprised centering on the central axis with a drive mechanism. Therefore, the polishing body 20 comes into contact with the dirt on the top plate 51 while the surface in contact with the dirt always rotates in a constant state. Therefore, it is not necessary for the user to move the polishing body 20 back and forth, right and left, and the dirt on the top plate 51 is removed simply by pressing, so that the cleaning tool 1 is easy to use.

  Further, since the polishing body 20 is formed in a spherical crown shape, for example, even if the polishing cloth 40 is pressed against the flat plate 51 with the cleaning tool 1 slightly tilted, the polishing cloth 40 with respect to the flat plate 51 on the surface to which the dirt has adhered is applied. The contact angle is always constant. Accordingly, the contact area between the polishing cloth 40 and the top plate 51 is always small, so that the dirt on the flat plate 51 can be removed stably.

  Next, referring to (2), in the conventional cleaning tool 60, for example, the polishing body 61 is formed in a cylindrical shape with a flat end. And when such a grinding | polishing body 61 is pressed on the top plate 51 of an electromagnetic cooker, the polishing cloth 62 will contact the top plate 51 over a wide range. Therefore, as shown by the arrows in the figure, the force F pressing the polishing body 61 against the top plate 51 is dispersed at the contact portion between the polishing cloth 62 and the top plate 51. Therefore, in order to remove the dirt on the top plate 51, it is necessary to press the polishing body 61 with a greater force than the cleaning tool 1 shown in (1). It becomes difficult.

  In the above-described embodiment, the polishing body is formed in a spherical crown shape, but the surface in contact with dirt, such as a cross-sectional radiation shape, an elliptical spherical shape, or a polyhedron shape, is a convex surface shape toward the outside. If it is formed, it may be formed in other shapes. In that case, it is preferable to form the polishing body in a rotationally symmetric shape so that the rotating polishing body stably contacts the dirt.

  Further, in the above embodiment, the polishing body is configured to rotate by the drive mechanism and the battery, but the drive mechanism and the like may be omitted, and the polishing body is fixed by moving the polishing body forward, backward, left and right. It may be configured to remove dirt.

  Furthermore, in the above-described embodiment, the abrasive body includes a base and an abrasive cloth that is detachably attached to the surface fastener of the base. However, the abrasive body is constituted by other members as long as it has a spherical crown shape. May be. Further, the polishing cloth may be attached to the base by another detaching method, for example, attached to the base with an adhesive.

  Further, in the above embodiment, the polishing body is connected to the motor via the speed reducer. However, if the polishing body can be rotated around its central axis, for example, the polishing body is directly connected to the motor. It may be configured as follows. In that case, it is necessary to increase the size of the motor in order to generate a specified torque, etc., and it is necessary to note that the usability may deteriorate.

  Furthermore, in the above-described embodiment, the base having a specific structure is provided. However, any structure having a spherical crown shape may be used.

  Furthermore, in the above embodiment, the polishing cloth having a specific structure is provided. However, other structures can be used as long as they can remove dirt and can be detachably attached to the base. May be.

  Furthermore, in the above-described embodiment, the grip body that houses the drive mechanism is provided, but the drive mechanism may not be housed in the grip body. Alternatively, the grip body may be omitted.

  Further, in the above-described embodiment, the battery is stored in the grasping body. However, the battery may be configured to supply power to the drive mechanism via, for example, a fixed rechargeable battery or a power cord.

  Here, it experimented about the removal effect of the stain | pollution | contamination fixed on the glass top plate of an electromagnetic cooker by the various dimension in the cleaning tool of 1st Embodiment.

  First, the configurations and experimental methods of Examples 1 to 4 and Comparative Examples 1 to 3 will be described.

  In Example 1, the shape of the base material was a spherical crown shape, and the radius A of the spherical crown shape portion of the base material shown in FIG.

  In Example 2, the shape of the base material was a spherical crown shape, and the radius A of the spherical crown shape portion of the base material shown in FIG.

  In Example 3, the shape of the base material was a spherical crown shape, and the radius A of the spherical crown shape portion of the base material shown in (1) of FIG. 9 was 20 mm.

  In Example 4, the shape of the base material was a spherical crown shape, and the radius A of the spherical crown shape portion of the base material shown in (1) of FIG. 9 was 25 mm.

  In Comparative Example 1, the shape of the base material was a cylindrical shape, and the radius B of the cylindrical portion of the base material shown in FIG.

  In Comparative Example 2, the shape of the base material was a cylindrical shape, and the radius B of the cylindrical portion of the base material shown in FIG.

  In Comparative Example 3, the base material had a cylindrical shape, and the radius B of the cylindrical portion of the base material shown in FIG.

  In all of the above Examples 1 to 4 and Comparative Examples 1 to 3, anhydrous gypsum (Mohs hardness 3.5) is used for the polishing layer of the polishing cloth, and the rotational torque of the polishing body is 2.0 kg · cm, and the number of revolutions when the abrasive was not loaded was 200 rpm.

  And using each said sample, the stain | pollution | contamination (Mohs hardness 1-2) fixed on the glass top plate of an electromagnetic cooker was performed, and the removal condition of the stain | contamination was confirmed visually. In addition, about the contact area of the polishing cloth in Examples 1 to 4, the polishing cloth in each sample was pressed against the aluminum foil spread on the top plate with a force for actually working, and the traces remaining on the aluminum foil at that time were measured. The area was calculated. Moreover, about the contact area of the polishing cloth in Comparative Examples 1-3, it computed from the area of the circle | round | yen for every radius of each sample.

上記の表を参照して、実施例１〜３においては汚れの取れ具合が良好であり、汚れを落としやすいことが確認出来た。更に、実施例１〜３においては、研磨布を押し付けてもモーターの回転（研磨布の回転）に変化が無かった。しかしながら、実施例１においては実施例２、３に比べて研磨布の接触面積が極めて小さいため、広範囲の汚れを除去するのに時間がかかってしまう。

With reference to said table | surface, in Examples 1-3, it was able to confirm that the removal condition of dirt was favorable and it was easy to remove dirt. Further, in Examples 1 to 3, even when the polishing cloth was pressed, the rotation of the motor (rotation of the polishing cloth) did not change. However, in Example 1, since the contact area of the polishing cloth is extremely small compared to Examples 2 and 3, it takes time to remove a wide range of dirt.

  In Example 4, although the dirt removal effect was a little inferior to Examples 1-3, it was confirmed that the dirt was removed. Regarding the rotation of the motor, the rotation speed was slightly reduced by pressing the polishing cloth.

  In Comparative Examples 1 to 3, it was confirmed that it was difficult to remove dirt. Furthermore, in Comparative Examples 2 and 3, since the rotation of the motor was stopped by pressing the polishing cloth, the effect of removing dirt could not be exhibited.

  From the above results, it was possible to confirm the dirt removal effect for Examples 1 to 4 according to the present invention, but it was not possible to confirm the dirt removal effect for conventional Comparative Examples 1 to 3. That is, it can be said that the effect of the cleaning tool according to the present invention has been verified.

Furthermore, when each of Examples 1-4 was compared, the cleaning tool by Examples 1-3 was a thing with a high removal effect of especially dirt. Therefore, when the torque of the polishing body is 2.0 kg · cm and the rotation speed is 200 rpm, the size of the spherical crown-shaped substrate is particularly effective when the SR is 20 mm or less (the contact area of the polishing cloth is 2.8 cm ² or less). I was able to confirm.
