A46B2200/3066—Brush specifically designed for use with street cleaning machinery
The present invention relates to a cleaning tool for simultaneously cleaning a floor surface or the like with a rotating brush and a wiping material.
As a cleaning tool for cleaning the carpet, push (or pull) a handle that has a wheel and a rotating brush that rotates around the horizontal rotation axis in conjunction with the wheel. There are some which run while rolling the wheel on the carpet, sweep up the dust on the carpet with a rotating brush that rotates in conjunction with the wheel, and store it in the dust container in the cleaning tool.
However, when this type of cleaning equipment is used for cleaning relatively flat surfaces such as floors, board materials, plastic materials, etc. and floor surfaces such as tatami surfaces, it is difficult to sufficiently sweep up the dust. In many cases, dusts, particularly fine dusts, remained on the surface.
On the other hand, in the cleaning of various floor surfaces, one that attaches a wiping material such as a nonwoven fabric to the lower surface of the mop head to clean the floor surface is often used. However, in the case of a mop using such a wiping material, there is a lack of ability to wipe off relatively large dust on the floor surface.
Japanese Patent Application Laid-Open No. 61-32127 discloses that “a rotating brush having driving wheels with slightly small diameters at both ends in a main body case having an open bottom surface, and a lower portion of the driving wheel projecting from below the main body case. A dust room for receiving dust in the vicinity of the rotating brush in the main body case, and in close proximity to the rear of the rotating brush and in contact with the floor surface, and the rotating brush. "A floor cleaner" characterized in that a mop having a shape substantially along the outer periphery of the floor is disposed.
In this floor cleaner, the rotation of the rotating brush sweeps the dust off the floor along the mop that has a shape that substantially follows the outer periphery of the rotating brush, and stores it in the dust room. wipe. The dust that has not been swept up is collected and stopped at the tip of the mop by the movement of the mop, and is therefore swept up by the continuous sweeping action by the rotation of the rotating brush and stored in the dust room.
However, since the mop of this floor cleaner needs to have a shape that substantially follows the outer periphery of the rotating brush, it is not possible to use a sheet-like wiping material such as a nonwoven fabric or a normal wiping material such as a dust cloth, Moreover, the mop was damaged by the continuous rotation of the rotating brush in contact with the mop, and the lifetime of the wiping material was shortened.
The present invention has been made in view of the above-described problems existing in the prior art, and the object of the present invention is to use various types of floor surfaces, tatami surfaces, etc., without damaging durability. An object of the present invention is to provide a cleaning tool that can perform cleaning efficiently and reliably.
The cleaning tool of the present invention that achieves the above-described object provides:
A rotating brush supported so as to be rotatable about a horizontal rotation axis, a driving device that rotationally drives the rotating brush, a dust container that accommodates dust that has been swept up by the rotation of the rotating brush,SheetThe wiping material support bottom that supports the wiping material so that it can be pressed against the surface to be cleaned, and the wiping material support bottomSheetIn the state that supported the wiping materialSheetIt is a cleaning tool provided with a wiping material fixing part for detachably fixing the wiping material,
The wiping material support bottom is provided on a side of the rotating brush,
The rotating brush is disposed on the wiping material support bottom.SheetIn a state where the wiping material is supported and brought into contact with the surface to be cleaned, at least the lower end portion of the rotating brush is supported so as to contact the surface to be cleaned,
The drive device rotates the rotating brush by rolling of a rolling member that can roll on the surface to be cleaned,
The wiping material fixing portion is a sheet-like wiping supported by the wiping material support bottom portion between the rotating brush and the wiping material support bottom portion or above the wiping material support bottom portion at a position close to the rotation brush in the wiping material support bottom portion. The edge of the rotating brush side of the material can be detachably fixed,
Supported by the wiping material support bottomSheetIt has the isolation | separation part which isolate | separates a wiping material and the said rotary brush.
A relatively large dust such as the floor surface to be cleaned is swept up by the rotation of the rotating brush and accommodated in the dust accommodating part, and supported at the same time as the wiping material support bottom.SheetThe floor surface or the like can be wiped while pressing the wiping material against the floor surface or the like. As a result, the portion where relatively large dust that can wipe down relatively fine dust on the floor surface or the like that has been swept away can be removed.SheetSince it will wipe with a wiping material, various floor surfaces, tatami surfaces, etc. can be cleaned efficiently and reliably.SheetSince the wiping material is detachably fixed to the wiping material fixing portion while being supported on the wiping material support bottom, it can be used at any time,SheetSince the wiping material is separated by the separation part,SheetDamage to the wiping material and deterioration of durability are prevented.
The cleaning tool of the present invention may be provided with a rotating brush, a driving device, a dust container, a wiping material support bottom, a wiping material fixing part, a separating part, a handle or a handle, etc. on a base. For example, the base body may have a substantially box shape or a frame shape.
One or more rotating brushes can be provided. For example, two or more rotating brushes can be provided in parallel, and two or more rotating brushes can be provided in series in the rotation axis direction. The rotating brush may be covered with the base of the cleaning tool, a rolling member described later, or other members, except for a portion communicating with the dust container and a portion facing the surface to be cleaned.
For example, the driving device is provided with a rolling member such as a wheel or a roller on the cleaning tool, and the rolling member and the rotating brush are fixed on the same rotation shaft, or the rolling member and the rotating brush are endlessly transmitted such as an endless belt. When the cleaning tool is run on the surface to be cleaned while rotating the rolling member on the surface to be cleaned, the rotary brush is driven to rotate by interlocking via a transmission mechanism using means or gears. Can be. When interlocking via a transmission mechanism, the rotational speed (angular velocity) of the rotating brush can be made higher than the rotational speed of the rolling member, or the rotational direction of the rotating brush can be reversed from the rotational direction of the rolling member. CanThe
When the rotary brush is driven by rolling of the rolling member, the rotation direction of the rotary brush is such that the cleaning tool is cleaned so that the bottom of the wiping material support follows the rotary brush in the direction perpendicular to the rotation axis of the rotary brush. It is preferable that the lower part of the rotary brush rotate backward when it travels on the surface. In this case, the direction of rolling of the rolling member and the direction of rotation of the rotating brush coincide. However, the direction of rotation of the rotating brush can be reversed.The In additionFor example, the rotary brush can be provided before and after the wiping material support bottom, or the wiping material support bottom can be provided before and after the rotation brush.
The cleaning tool of the present invention is formed with an inclined surface that forms a sweeping inclined surface (curved surface or flat surface) that is substantially along the outer periphery of the rotating brush and whose lower end edge faces the surface to be cleaned, on the side where the lower portion of the rotating brush advances by rotation. It is preferable to have a portion (usually extending parallel to the rotation axis of the rotating brush). This is because the dust on the surface to be cleaned can be swept up with high certainty along the inclined surface for sweeping by the rotation of the rotating brush. If the direction of rotation of the rotating brush can be reversed due to the rolling direction of the rolling member, etc., the main rotation [when the rotating brush is driven by the rolling of the rolling member, is orthogonal to the rotation axis of the rotating brush. The main rotation is preferably the rotation when the cleaning implement is run on the surface to be cleaned so that the wiping material support bottom follows the rotating brush in the direction. ], The inclined surface forming portion may be provided only on the side where the lower portion of the rotating brush advances, but it can also be provided on both sides.
Such an inclined surface forming portion is preferably supported so as to be movable up and down so that it can be moved upward by being pushed up by the convex portion of the surface to be cleaned and can be returned to its original position by releasing the push-up. In this case, when the inclined surface forming portion moves up and down with respect to the cleaning implement, the state where the lower end edge of the sweeping inclined surface faces the surface to be cleaned is maintained as much as possible. While cleaning up the dust with high certainty along the inclined surface for sweeping, when the inclined surface forming part does not move up and down and is fixed to the cleaning tool, the cleaning tool is moved together with the inclined surface forming part by the convex portion of the surface to be cleaned. Pushed up and supported by rotating brush or wipe support bottomSheetIt is possible to prevent the wiping material from being lifted from the surface to be cleaned and to reduce the cleaning effect. Specifically, for example, at least a pair of upper and lower protrusions or vertical protrusions are provided at both ends of the inclined surface forming part, and the upper and lower protrusions or the vertical protrusions are fitted to the base of the cleaning tool. By providing a guide groove in a substantially vertical direction and making the vertical length of the guide groove longer than the distance between the upper and lower ends of the protrusion or protrusion, the protrusion or protrusion is guided and the inclined surface forming part moves up and down. Can be. Further, the protrusions or ridges can be provided on the base body, and the substantially vertical groove can be provided on the inclined surface forming part.
The dust that has been swept up by the rotation of the rotating brush is caused by centrifugal force due to the rotation, or when the comb-shaped part is provided so as to whisper the rotating brush (for separating the dust entangled with the rotating brush), etc. , Separated from the rotating brush and housed in the dust container.
The wiping material support bottom is provided on the side of the rotating brush (that is, one or both in the direction perpendicular to the rotation axis of the rotating brush),SheetThe wiping material is supported so as to be pressed against the surface to be cleaned.As the wiping material, a sheet-like wiping material, more preferablyThe sheet-like wiping material made of nonwoven fabric can be used by dry wiping or in a wet state using water or other liquid. The bottom surface side of the wiping material support bottom is preferably made of a cushioning material such as foamed plastic or sponge rubber. The rotating brush is attached to the bottom of the wiping material support.SheetIn a state where the wiping material is supported and brought into contact with the surface to be cleaned, it is rotatably supported so that at least the lower end portion of the rotating brush contacts the surface to be cleaned.
The wiping material fixing part is on the wiping material support bottom.SheetIn the state that supported the wiping materialSheetThe wiping material is detachably fixed, and can be provided at one place or a plurality of places. When a sheet-like wiping material is used, the wiping material support bottom can support the sheet-like wiping material so that it can be pressed against the surface to be cleaned, and the wiping material fixing part is placed on the wiping material support bottom. It is necessary that the sheet-like wiping material can be detachably fixed in a state where the material is supported.
The wiping material fixing part is, for example,SheetA clip part that can hold the wiping material in a detachable manner,SheetA surface fastener that can hold the wiping material, a plurality of elastic tongues that can bend elastically in the thickness direction, or between an elastic tongue and a rigid portion that can bend elastically in the thickness direction A holding portion that can hold and hold between a concave portion and a convex portion fitted to the concave portion or a convex portion of the holding portion, preferably a holding portion that can be hooked and held on a plurality of rigid pointed portions (for example, a saw blade shape portion), Adhesive part with adhesive, etc.,Sheet1 type or 2 types or more, such as the part which the adhesion part provided in the wiping material can adhere | attach so that attachment or detachment is possible, can be provided in dot shape, linear form, or planar form.
Sheet-like wipes such as non-woven sheet-like wipesFor example, sheetOne end edge of the wiping material is fixed to a wiping material fixing part provided between the wiping material support bottom and the rotating brush or at a position near the rotating brush among the wiping material supporting bottom, and the other end edge is fixed to the wiping material supporting bottom. The position far from the rotating brush or the position away from the wiping material support bottom as viewed from the lower end of the rotating brush (for example, the upper surface farther than the wiping material supporting bottom or the upper surface positioned above the wiping material supporting bottom To the wiping material fixing part provided in the part).
When using sheet-like wipes such as non-woven sheet-like wipesThe wiping material support bottom is supported between the rotating brush and the wiping material support bottom or above the wiping material support bottom at a position near the rotating brush in the wiping material support bottom.SheetIt is preferable to have the wiping material fixing | fixed part which can fix the edge part by the side of the rotating brush of a wiping material so that attachment or detachment is possible. By doing in this way, when the cleaning implement is run on the surface to be cleaned such that the wiping material support bottom continues behind the rotary brush in the direction orthogonal to the rotation axis of the rotary brush,Sheet-like wipesIt can be avoided that the front end edge portion becomes unusable due to friction with the surface to be cleaned.
In this case, there is a wiping material retaining groove parallel to the rotation axis that opens downward between the rotating brush and the wiping material supporting bottom or at a position near the rotating brush in the wiping material supporting bottom, and in the wiping material retaining groove. It may have a wiping material fixing part. Any of the above examples can be used as the wiping material fixing portion in this case. In particular, by using a wiping material retaining ridge that fits detachably in this wiping material retaining groove,Sheet-like wipesThe edge of the one end can be held under pressure, and in this case, the wiping material retaining groove itself constitutes the wiping material fixing portion.
Also, when running in the opposite direction to the above (when running the cleaning tool on the surface to be cleaned so that the rotating brush continues behind the wiping material support bottom in the direction perpendicular to the rotation axis of the rotating brush),Sheet-like wipesAn upper position where the other end edge is separated from the bottom of the wiping material when viewed from the lower end of the rotating brush in order to prevent the other end edge from being used due to friction with the surface to be cleaned. It is preferable to have a wiping material fixing part.
Moreover, the cleaning tool of the present invention has a support bottom constituent member that constitutes at least a part of the wiping material support bottom, and the support bottom constituent member has a rotation axis (preferably a rotation axis) parallel to the rotation axis of the rotary brush. State that can be opened and closed by rotation about its rotation axis, and has a wiping material fixing part on the upper side, and the supporting bottom component member is closed In the wiping material support bottomSheetThe wiping material can be supported so that it can be pressed against the surface to be cleaned. For example, the upper surface of the supporting bottom component member can be supported by the bottom plate portion of the dust container. Any of the above examples can be used as the wiping material fixing portion. In particular, by providing a wiping material retaining projection or a wiping material retaining projection plate detachably fitted in the wiping material retaining groove as described above at the end of the supporting bottom component member, Between the twoSheet-like wipesThe edge portion at one end can be held under pressure, and in this case, the ridge portion for wiping material constitutes the wiping material fixing portion. In such a case, a wiping material fixing part such as an adhesive or an elastic tongue piece can be further provided on the bottom surface part of the supporting bottom part constituting member constituting at least a part of the wiping material supporting bottom part.
The separation part was supported by the wiping material support bottomSheetIt is for separating the wiping material and the rotating brush, and preferably has such an inclined surface forming portion as at least a part of the separating portion. More preferably, the inclined surface forming portion is supported so as to be movable up and down so that it can be moved upward by being pushed up by the convex portion of the cleaning surface, and can be returned to the original position by releasing the push-up. However, a wall-like part other than such an inclined surface forming part, a partition part, a projecting ridge part protruding downward, and the like can be used as the separating part.

FIG. 1 is an explanatory sectional view of the cleaning tool at the time of cleaning use, FIG. 2 is an enlarged view of a main part of FIG. 1, and FIG. 4 is a rear sectional perspective view of the cleaning tool when the wiping material is attached, FIG. 5 is an explanatory sectional view of the cleaning tool when the wiping material is attached to the rear edge, and FIG. FIG. 7 is an explanatory cross-sectional view of the cleaning tool when removing the wiping material and discharging the dust, and FIG. 7 is a rear upper perspective view of the cleaning tool when discharging the dust.
This cleaning device is a substantially box-shaped base body provided with a dust container 10a, an elastic tongue holder mounting plate 10b, a brush cover 10c, a front upper part 10d, an inclined surface forming part 10e, and a wiping material retaining groove 10f. 10, a rotating brush 12, a driving wheel 14, an opening / closing lid 16, a support bottom component member 20, an elastic tongue holding member 22, and a handle support 23 are provided.
Below the brush cover portion 10c located at the front portion (left end portion in FIG. 1) of the base body 10, the drive wheels 14 are coaxially arranged at both ends of the rotating shaft 12a in the horizontal lateral direction (direction perpendicular to the plane of FIG. 1). A rotating brush 12 fixed to the rotating shaft 12 is rotatably supported at both ends of the rotating shaft 12a. The outer envelope surface of the rotating brush 12 protrudes slightly from the outer periphery of the drive wheel 14.
The inclined surface forming portion 10e constitutes a sweeping inclined surface 10e1 whose front surface substantially extends along the outer periphery of the lower rear portion over the entire length of the rotary brush 12, and the lower end edge of the sweeping inclined surface 10e1 is the surface 26 to be cleaned. Come on. The inclined surface forming portion 10e has a plate shape extending in parallel with the rotation shaft 12a of the rotating brush 12, and is curved in a side view.
The dust container 10a is a box-shaped part located behind the rotary brush 12 in the base 10, and communicates with the rear upper part of the rotary brush 12 in an upper part of the front standing upper part 10d. The upper portion of the dust container 10a is opened and closed by an opening / closing lid 16 having a horizontal rotation shaft at the front end, and rotates in a state where the opening / closing lid 16 is closed at the front lower portion of the opening / closing lid 16 as shown in FIG. A comb-like portion 18 is provided at a position where the brush 12 is combed.
Between the inclined surface forming portion 10e and the upright upper portion 10d, a wiping material holding groove portion 10f that opens downward and is parallel to the rotating shaft 12a of the rotating brush 12 is formed.
A vertical plate-like elastic tongue holding body mounting plate portion 10b is formed at the rear end portion of the base body 10 with a space portion 10h between the rear portion of the dust storage portion 10a. The elastic tongue piece holders 22 are fitted and fixed in the fitting holes provided in the left and right portions of the elastic tongue piece holder mounting plate portion 10b. The elastic tongue holding member 22 has a fan shape in which an elliptical plate parallel to the elastic tongue holding member mounting plate 10b is divided into six at the center, the base is fixed to the outer peripheral portion, and the tip end side is elastic in the thickness direction. It consists of elastic tongue piece 22a which can bend flexibly.
The supporting bottom portion constituting member 20 has a flat plate shape extending over almost the entire width of the base body 10 and has a cushion portion 20a over the entire lower surface side, and a rotation shaft portion 20c parallel to the rotation axis of the rotary brush 12 at the rear end portion. In this case, the base 10 is connected to the lower portion of the rear end, and can be opened and closed by turning around the turning shaft portion 20c. At the front end of the support bottom component member 20, a wiping material retaining projection 20 b projects upward. In the state where the support bottom component member 20 is closed, the cushion portion 20a constitutes the wiping material support bottom. The operation portion 20d provided on the left and right side portions of the support bottom component member 20 prevents the operator's finger from slipping and facilitates the opening / closing operation of the support bottom component member 20.
The front edge of the non-woven sheet-like wiping material 24 having a square shape (not limited to this) with the support bottom component member 20 opened is covered over the front side and the rear side of the wiping material retaining projection 20b. Then, as shown by the arrows in FIG. 3, the sheet-like wiping material 24 is rotated by rotating the support bottom component member 20 and fitting and fixing the wiping material retaining protrusion 20b to the wiping material retaining groove 10f from below. Is held between the wiping material holding projection plate 20b and the wiping material holding groove 10f. Thereafter, as shown in FIG. 5, the left and right portions of the rear edge of the sheet-like wiping material 24 are pushed into the respective elastic tongue piece holders 22 from the rear, so that the sheet-like wiping is made between the pointed ends of the elastic tongue pieces 22 a. The trailing edge of the material 24 is retained. In this way, as shown in FIG. 1, the upper surface of the flat bottom portion of the support bottom component member 20 is supported by the bottom surface of the dust container 10a, and below the cushion portion 20a of the support bottom component member 20. In a state where the sheet-like wiping material 24 is supported so as to be pressed against the surface 26 to be cleaned, the sheet-like wiping material 24 is fixedly held by the cleaning tool. For example, by providing the elastic tongue piece holder 22 on the upper surface portion of the base body 10, the rear edge portion of the sheet-like wiping material 24 can be fixedly held on the rear upper surface of the cleaning tool. Further, the wiping material retaining projection 20b in FIGS. 3 and 4 shows a mode in which a projection is provided on the front side, and this projection is the rear side surface of the inclined surface forming portion 10e (the right side in FIG. 3). By fitting in a recess (not shown) provided on the surface), the fitting and fixing of the wiping material retaining projection 20b to the wiping material retaining groove 10f is reliably used.
The handle support 23 is rotatably attached to the base body 10 at both ends having a bifurcated shape, and includes a handle connecting portion 23a capable of fitting and fixing the handle at the center.
When the cleaning implement to which the sheet-like wiping material 24 is attached is placed on the surface to be cleaned 26, the sheet-like wiping material 24 comes into contact with the surface to be cleaned 26, and the lower end portion of the rotary brush 12 is in contact with the surface to be cleaned 26. In this state, when the vehicle is moved forward as indicated by arrows in FIGS. 1 and 2, the rotating brush 12 rotates counterclockwise in FIGS. 1 and 2 as the drive wheel 14 rolls on the surface 26 to be cleaned. As the brush 12 rotates, the dust 28 on the surface 26 to be cleaned is swept up while being guided by the sweeping inclined surface 10e1 of the inclined surface forming portion 10e, and rotated by the centrifugal force generated by the rotation of the rotating brush 12 and the comb-shaped portion 18. The dust 28 is separated from the rotating brush 12 due to the brush 12 being sown, and is accommodated in the dust accommodating portion 10 a that leads to the upper rear of the rotating brush 12. At substantially the same time, the cleaning target surface 26 can be wiped while pressing the sheet-like wiping material 24 supported by the cushion portion 20a of the support bottom component member 20 against the cleaning target surface 26. As a result, the sheet-like wiping material 24 wipes the portion where the relatively large dust 28 that can reduce the efficiency of wiping off the relatively fine dust 28 on the surface 26 to be cleaned is wiped off. 26 can be cleaned efficiently and reliably. Since the sheet-like wiping material 24 is detachably fixed in a state of being supported by the cushion portion 20a, it can be used at any time, and the rotary brush 12 and the sheet-like wiping material 24 are separated by the inclined surface forming portion 10e. Damage to the sheet-like wiping material 24 due to rotation of the rotating brush 12 and deterioration of durability are prevented.
After fully using the sheet-like wiping material 24, as shown by the arrow in FIG. 6, the supporting bottom portion constituting member 20 is rotated to remove the wiping material holding projecting plate portion 20b from the wiping material holding groove portion 10f. The sheet-like wiping material 24 can be removed from the cleaning tool by releasing the fixing and holding of the front edge portion of the wiping material 24 and removing the rear edge of the sheet-like wiping material 24 from each elastic tongue piece holder 22. it can. Moreover, the dust 28 accommodated in the dust accommodating part 10a can be discharged | emitted by opening the opening-and-closing lid 16 as shown in FIG.
8 and 9 relate to another example of the cleaning tool of the present invention. FIG. 8 is an enlarged sectional view of a main part of the cleaning tool when used for cleaning, and FIG. 9 is an enlarged explanatory view of the main part. It is.
The inclined surface forming part 40 in this example has a pair of upper and lower protrusions 40a projecting laterally at both ends, and is fitted in the base 10 of the cleaning tool in a substantially vertical direction that fits with the pair of upper and lower protrusions 40a. By providing the guide groove 10g and making the vertical length of the guide groove 10g longer than the distance between the upper and lower ends of both protrusions 40a, the protrusion 40a is guided by the guide groove 10g and the inclined surface forming part 40 can move up and down. It is. The inclined surface forming portion 40 forms a sweeping inclined surface 40b whose front surface substantially extends along the outer periphery of the lower portion of the rear side over almost the entire length of the rotary brush 12, and the lower end edge of the sweeping inclined surface 40b is the surface 26 to be cleaned. Come on. The inclined surface forming portion 40 has a plate shape extending in parallel with the rotation shaft 12a of the rotating brush 12, and is curved in a side view.
The inclined surface forming portion 40 can be moved upward by being pushed up by the convex portion 26a of the surface 26 to be cleaned, and can be returned to the original position by releasing the pushing. In this case, when the inclined surface forming portion 40 moves up and down with respect to the cleaning tool, the state where the lower end edge of the sweeping inclined surface 40b faces the surface to be cleaned 26 is maintained as much as possible, and cleaning is performed by the rotation of the rotary brush 12. While the dust 28 on the target surface 26 is swept up with certainty along the sweeping inclined surface 40b, the convex portion 26a of the cleaning target surface 26 is fixed when the inclined surface forming portion does not move up and down and is fixed to the cleaning tool. As a result, the cleaning tool is pushed up together with the inclined surface forming portion 40 and the sheet-like wiping material 24 supported by the cushion portion 20a of the rotating brush 12 or the supporting bottom portion constituting member 20 is prevented from floating from the surface 26 to be cleaned, thereby reducing the cleaning effect. Can be prevented.
FIG. 10 is an explanatory view showing another driving mode of the rotating brush in the cleaning tool of the present invention. In this case, the rotating shaft 14a of the driving wheel 14 and the rotating shaft 12a of the rotating brush 12 are separately rotatably supported, and the diameter of the rotating shaft 14a of the driving wheel 14 is made larger than the diameter of the rotating shaft 12a of the rotating brush 12. At the same time, the endless belt 30 is stretched between the rotating shaft 14a and the rotating shaft 12a so that the rotation speed (angular velocity) of the rotating brush 12 is higher than the rotating speed of the driving wheel 14 in conjunction with each other to increase the sweeping efficiency. To do. In FIG. 10, the drive wheel 14 and the rotary brush 12 are separated from each other in the front-rear direction, but it is of course possible to position the rotary shaft 12 a of the rotary brush 12 within the radius of the drive wheel 14.
FIG. 11 is an explanatory view showing still another driving mode of the rotating brush in the cleaning tool of the present invention. In this case, the tooth part 14b is provided on the inner peripheral part of the outer ring part of the drive wheel 14, and the tooth part meshing with the tooth part 14b is provided on the outer periphery of the rotary shaft 12a of the rotary brush 12, and the rotary brush is operated by linking them together. The rotational speed (angular velocity) of 12 is higher than the rotational speed of the drive wheel 14 to increase the sweeping efficiency.
Note that the vertical positional relationship in the description of the above embodiments is merely for convenience of explanation based on the drawings, and does not limit the actual use state or the like.
The explanation including the example and the numerical range described in the section of the means for solving the problem including the numerical range applies in principle to the description of the above embodiment.
According to the cleaning tool of the present invention, a relatively large dust such as a floor surface is swept away with a rotating brush almost simultaneously.SheetBy wiping the floor surface with a wiping material, remove the relatively large dust that has been swept away, which can reduce the efficiency of wiping off relatively fine dust on the floor surface, etc.SheetSince it will wipe with a wiping material, various floor surfaces, tatami surfaces, etc. can be cleaned efficiently and reliably.SheetSince the wiping material is detachably fixed to the wiping material fixing portion while being supported on the wiping material support bottom, it can be used at any time,SheetSince the wiping material is separated by the separation part,SheetDamage to the wiping material and deterioration of durability are prevented.
