Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor suction device for a vacuum cleaner, and more particularly to a floor suction device that can efficiently clean not only dust by suction but also by wiping the floor.
[0002]
[Prior art]
Conventionally, a floor suction device of a vacuum cleaner is provided with a rotating brush provided with a bristle brush or a rubber blade, and the rotating brush is driven to rotate when the vacuum cleaner is running to scrape off dust on the floor surface. In addition, the cleaner can be efficiently cleaned by sucking the scraped dust.
[0003]
The method of sucking and cleaning the dust after scraping the dust with such a rotating brush is effective particularly for tatami mats, carpets and the like, since the cleaning effect is good and the dust and the like are efficiently removed.
[0004]
However, for example, dust and dirt adhering to flooring floors cannot be sufficiently removed by such suction cleaning, and such dust can be more thoroughly cleaned by wiping with a rag. Is superior. In particular, in recent years, the number of rooms on the floor (flooring) has increased between tatami mats and carpets, and from this point of view, cleaning by wiping is also useful.
[0005]
Therefore, as a floor suction device of a conventional vacuum cleaner, a cloth member such as a pile-shaped member to which dust easily adheres to the rotating brush is provided in order to have a function of simultaneously performing suction and wiping of wooden floors and tatami mats. A spirally affixed one (for example, Patent Literature 1) or a configuration in which a similar cloth member is provided at the tip of a blade portion of a rotating brush (for example, Patent Literature 2) are proposed, and cleaning is performed by such a method. Techniques for doing so are known.

[Problems to be solved by the invention]
However, in the structure disclosed in Patent Document 1, the cloth member is attached to the rotating brush, so that in order to remove the cloth member from the rotating brush at the time of garbage disposal, the cloth member must be peeled off, and the removal work is troublesome. there were. Also, when replacing the suction device, it is necessary to turn the suction tool over and wrap the cloth member around the rotating brush in the narrow case space, and do not stick an adhesive cloth member to the suction tool body case other than the rotating brush. There was a difficulty that it had to be carefully attached with care.
[0008]
Further, in the device disclosed in Patent Document 2, since a cloth blade portion is separately formed in front of the blade portion of the rotating brush, the rotating brush has a complicated structure, and the cloth blade is consumed. When replacing the rotary brush, it is difficult to say that the entire rotary brush needs to be replaced, and that the rotary brush itself is not enough in terms of practicality such as troublesome reattachment.
[0009]
The present invention has been made in view of the above points, and a dust-adhesive sheet is automatically wound around a rotating brush by the rotation of the rotating brush, and can be mounted. Wiping cleaning and polishing exerted by the rotation of the mounted sheet can be performed. According to the present invention, it is possible to provide a floor suction tool and a dust suction sheet to be attached to a rotating brush, which can further improve the cleaning property and can be very easily performed by rewinding the sheet. Things.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention relates to a floor suction device having a structure in which a rotating brush is housed inside a main body case of a suction device having an elongated lower surface opening in a lateral direction and facing the lower surface opening. The rotary brush has a structure in which a dust suction sheet can be automatically wound.
[0011]
In addition, the rotating brush is provided with a plurality of brush bodies having different bristle lengths and hardnesses in a spiral shape in the axial direction on the peripheral surface.
[0012]
One of the brush bodies is composed of a pair of long and soft bristle brushes disposed outside and a short and hard bristle brush disposed inside.
[0013]
In addition, the rotating brush includes a plurality of arranged brush bodies attached to a spiral groove provided in an axial direction on a peripheral surface of the core body, and so as to fill a space between the brush body and the brush body. A plurality of ribs are formed so as to protrude from the outer periphery of the core so as to be close to the root of the brush.
[0014]
Further, the front wall of the main body case is constituted by a cover which can be opened and closed in a vertical direction, and communicates with the lower surface opening at the front portion of the suction port so that the suction sheet can be easily taken out when the cover is opened. The configuration is such that an opening that appears.
[0015]
A roller is provided at the front end of the cover to act as a bumper at the time of contact between the suction tool and the wall surface. The suction sheet is inserted from above through a gap between the roller and the upper surface of the cover, and is fed by the roller. It is constituted so that it can be performed.
[0016]
Further, on the outer peripheral surface of the roller, there is provided a resistance member such as a raised cloth for increasing a contact resistance with the suction sheet.
[0017]
Further, the cover may be formed of a transparent material or provided with a viewing window so that the state of winding of the suction sheet can be checked.
[0018]
Further, the dust suction sheet is provided in a floor suction device having a structure in which a rotating brush is housed inside the main body case of the suction device having an elongated lower surface opening in the lateral direction, facing the lower surface opening. A locking means is formed at the front end of the rotary brush so that it can be wound around the rotating brush.
[0019]
The suction sheet has a shape obtained by diagonally cutting the rear shape.
[0020]
The suction sheet has a V-shaped cut in the rear shape.
[0021]
The suction sheet is provided with a string which is hooked on a rotating brush at a front end thereof.
[0022]
Further, the sheet has a hardened edge formed by sewing a wire or the like at a front end thereof.
[0023]
Further, a string is provided on both sides of a front end portion of the seat, and a hook portion of the string is provided on the rotating brush.
[0024]
In addition, the brush body is disposed on the peripheral surface of the core of the rotating brush so as to be V-shaped when the core is viewed horizontally.
[0025]
In addition, a V-shaped guide rib that is open in the axial direction that applies a force that slides on the suction sheet and extends in the axial direction of the rotating brush when the suction sheet is wound around the rotating brush is provided on the upper inner surface of the main body case. It was formed.
[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
The floor suction tool 1 shown in FIGS. 1 to 10 includes a horizontally long suction tool body case 2 including an upper case 2a and a lower case 2b, and having a suction port 6 formed in a wide range from the lower surface to the front surface. A rotary brush 3 rotatably supported at both ends in the longitudinal direction of the suction device main body case 2 through bearings, and communicates with the suction port 6 on the rear surface side of the suction device main case 2 and is rotatable vertically and horizontally. And a cover 5 which constitutes a front wall of the suction tool main body case 2 and opens and closes a front portion 6b of the suction port 6. The bend 4 is connected to an extension pipe or a hose (not shown). To be connected to the vacuum cleaner body.
[0027]
As shown in FIGS. 5 and 6, the rotating brush 3 has a brush body (or blade body) 8 on the outer peripheral surface of a core body 7 at an equal angle, for example, 90 ° or 60 ° in the longitudinal direction. A plurality of them are formed in a spiral shape. A specific method of providing the brush body 8 can be attached by fitting the root portion 8b into a spiral groove formed on the outer peripheral surface of the core body 7. Although not shown, the brush body 8 is configured so that its driving force is transmitted via a conductive belt or the like by an electric motor built in the suction tool main body case 2 and is driven to rotate. As the brush body 8 rotates, dust on the floor surface is scraped off, effectively sucked from the suction port 6, and efficiently cleaned.
[0028]
The cover 5, which is located close to the brush body 8 so as to cover the front part thereof, has arms (not shown) integrally formed at both ends in the longitudinal direction, and is formed inside the both ends of the main body case by the arms. It is rotatably supported. When the front end of the suction tool hits the wall surface when cleaning the wall or the like, the cover 5 rotates to rotate the cover 5 upward to open the front portion of the suction port 5. The roller 9 is rotatably mounted at both ends by bearings 9a, 9a. Here, the positional relationship between the rotating shaft of the cover 5 and the roller 9 is such that when the roller 9 at the forefront of the cover 5 is pressed against a wall surface or the like, the roller 5 rotates counterclockwise while the cover 5 rotates. The roller 9 is set so as to rotate upward so as to be positioned above a rotation axis that is the center of rotation of the cover 5, thereby opening the cover 5.
[0029]
Although not shown, the cover 5 has a configuration in which a torsion spring (not shown) is attached to a rotation shaft thereof as urging means for urging the cover 5 in a direction of turning the cover 5 downward. Therefore, during normal floor cleaning in which the front end of the suction tool does not hit a wall surface such as a wall, the cover 5 closes the front portion of the suction port 6 and opens only the lower portion. When the cover 5 is opened, as shown in FIG. 9, the cover 5 is formed in the upper case 2a so as to be stowed from the rear end so as to be housed inside the suction tool main body case 2. A hollow storage recess 10 is provided.
[0030]
The roller 9 also serves as a bumper for absorbing shock when the front side of the suction tool main body case 2 hits an obstacle during vacuuming. Therefore, as shown in FIG. It is preferable that the outer peripheral surface of the cylindrical body 11A having the outer surface 11 is covered with a raised cloth 11d which is a fibrous member as a soft and slippery contact member. The attachment can be reliably prevented, and the cover 5 can be rotated extremely smoothly. In addition, this is useful in that the left and right movements when cleaning in the horizontal direction while the roller 9 is in contact with the wall surface by the raised cloth 11d are also smooth.
[0031]
Now, as shown in FIG. 7, the rotating brush 3 of the suction tool 1 adsorbs dust such as cloth or paper, for example, kitchen paper, so as to enable a cleaning method similar to wiping with a rag. The obtained suction sheet 12 (hereinafter, abbreviated as a sheet) has a structure that can be automatically wound and mounted.
[0032]
Next, a specific configuration for mounting the seat 12 will be described with reference to FIGS. First, as shown in FIG. 7, FIG. 14, etc., the rectangular sheet 12 is placed in front of the suction tool 1 and the rotating brush 3 is evenly placed on the end of the sheet 12 as shown in FIGS. In this state, when the operation switch of the vacuum cleaner is turned on and the rotating brush 3 is rotated, the seat 12 is automatically entangled with the rotating brush 3 by the rotating brush 3 and mounted. When the sheet is mounted, the rotating brush 3 is controlled to rotate at a lower speed than that of a normal vacuum cleaner, so that the sheet 12 is prevented from being violently wound and damaged.
[0033]
Here, the rotating brush 3 has a structure in which the sheet 12 is easily wound. In a conventional rotary brush 14 having a general structure in which brush bodies 13b of the same length are simply provided at regular intervals (in this case, 90 °) on the outer periphery of a core body 7 as shown in FIG. There was a step D between a certain part and a non-part, and the sheet 12 was difficult to wind uniformly. Also, as shown in FIG. 23, when the sheet 12 is wound, the brush body 13b falls down from the root portion 13d due to the winding of the sheet 12, and remains deformed even after the sheet 12 is removed, so that the dust removing effect of the brush body 13b is poor. There was a problem of becoming.
[0034]
Therefore, in the present invention, a rotary brush having a structure that is easy to wind is realized by taking into account the length, quality (hard and soft) and arrangement of the brush body, and by taking measures to eliminate a step. The rotary brush 3A shown in FIGS. 24 to 26 has a first brush body 15 in which two long and soft bristle brushes 15a are arranged on the outside, and two short and hard bristle brushes 15b are arranged on the inside, and the longest is the longest. A rotating brush 3A comprising three types of brush bodies, a second brush body 16 having a bristle brush 16a planted therein and a third brush body 17 having a second length bristle brush 17a planted therein, and the first brush body thereof. Numerals 15 are spirally arranged on the outer peripheral surface of the core body 7 at 120 ° intervals along the three-row axial direction, and the second brush body 16 and the third brush body 17 are interposed therebetween so as to sandwich the first brush body 15. Are arranged.
[0035]
FIG. 26 shows a state in which the sheet 12 is wound around by the rotating brush 3A. When the leading end (front end) of the sheet 12 comes into contact with the rotating brush 3A, the brush 12 is retracted as the brush 3A rotates. Tangles around 17. When the sheet 12 is entangled, each of the three types of brush bodies 15 to 17 deforms (bends) according to the hardness (softness) of the bristles as shown in FIG. The inner surface is brought into contact with the inner surface without difficulty, and the sheet 12 maintains a round shape that does not distort. Thereby, the sheet 12 is wound in a state of being stretched round. Further, in the first brush body 15, the outer long bristle brush 15 a is kept in an upright state, and the bristle tip comes into contact with the inner surface of the sheet 12 at right angles. In this case, the three first brush bodies 115 are arranged at intervals of 120 degrees, so that the three brush bodies 15 uniformly support the inside of the sheet 12 at three points as a whole. It is useful to keep the sheet 12 tight and wind it evenly. Further, since the short brush body 15b of the first brush body 15 is not involved in the entanglement with the sheet 12, there is no problem that the root like the conventional brush body 3b is bent.
[0036]
Also, when the second and third brush bodies 16 and 17 are bent, any one of the first to third types of brush bodies is not provided with a large space on both sides of each other (to fill the space). Since the brush bodies 15 to 17 are present, the brush bodies 15 to 17 disperse the stress from the sheet 12 and bend appropriately, so that the brush body 13 b does not undergo extreme deformation such that the root of the conventional brush body 13 b is extremely bent. It is also possible to prevent the polishing effect from being lost due to the extreme bending of the fifteen to seventeen. In addition, three types of brush bodies 15 to 17 are uniformly arranged in a large number around the core body 7 in a total of seven, and the rotary brush 3A in which a step D between the brush bodies is eliminated, It is also possible to wind the sheet 12 while keeping the tension.
[0037]
The rotating brush 3B shown in FIG. 27 is another embodiment that enables sheet winding. In this case, the ribs 18 are provided on the core 7 of the rotating brush 3B. The ribs 18 have a bifurcated shape that is opened in an outward C-shape, and are integrally formed on the outer periphery of the core body 7 so as to be present between the brush bodies 19. . The ribs 18 are formed concentrically with the core body 7 and have a length shorter than that of the brush body 19. In the case of the rotary brush 3B having the ribs 18 so as to fill the space 20 between the brush bodies 19, the ribs 18 are similar to the conventional rotary brush 14, and the brush bodies which hinder the winding of the sheet 12 are provided. Since a step created between a portion having no and a portion having no is eliminated, the sheet 12 can be uniformly wound.
[0038]
By the way, as a method of attaching the sheet 12 to the rotating brush 3, it is also possible to adopt a configuration as shown in FIG.
[0039]
That is, in this configuration, the sheet 12 is inserted from the gap 22 between the front surface of the case 1 of the suction tool 1 and the roller 9 provided in the case 1, and the inserted sheet 12 is wound up by the rotating brush 3. Things. In this case, the entire front edge of the sheet 12 is pressed down by the rollers 9 which are long enough in the lateral direction so as to be more than the width of the sheet 12, and the left and right sides of the sheet 12 are guided by the rollers 9. As the sheet 9 is rotated, the sheet 12 is fed in a state where the entire surface of the sheet 12 is stretched uniformly, so that the rotating brush 3 can be wound uniformly. For this reason, when the sheet 12 described above is inserted into the rotary brush 3 in the suction port 6 from below the suction tool 1, the position shift that sometimes occurs when the sheet 12 and the rotary brush 3 are set may occur. As a result, the sheet 12 is attached diagonally, and a sufficient wiping effect cannot be obtained, and the front edge of the sheet 12 is crumpled and starts to be wound, It is advantageous in that the roller 12 can eliminate problems such as uneven mounting, and a problem that the end of winding of the sheet 12 hangs down on the floor surface to cause noise, for example. .
[0040]
When the sheet 12 is guided and fed using the roller 9, a brushed cloth 23 may be attached to the roller 9 as shown in FIG. 8. This is because if the roller 9 is a roller having a low resistance such as a resin, the roller 9 slides when guiding the sheet 12, and it may be difficult to obtain a desired uniform winding effect. A brushing cloth 23 is attached to the surface or the hair is implanted. If the outer peripheral portion of the roller 9 is formed of a material having resistance such as the brushed cloth 23, the contact resistance between the roller 9 and the sheet 12 is increased, and the entire surface of the sheet is stretched uniformly and more reliably and smoothly. This configuration is effective as a means for winding the sheet in that the sheet 12 can be wound around the rotating brush 3 in the air inlet 6 on average.
[0041]
As shown in FIG. 7 and the like, the sheet 12 is wound around the rotating brush 3 having the above-described structure and then rotated, so that dirt and dust on the floor surface are reliably wiped off by the sheet 12. In addition, the polishing effect is added, and the floor surface can be cleaned neatly.
[0042]
On the other hand, when wiping is completed and the dirty sheet 12 is discarded, or when a new sheet 12 is replaced and mounted, it is necessary to remove the sheet 12. When removing the sheet 12, as shown in FIG. 9, the free end 12d on the winding end side of the sheet 12 wound around the rotating brush 3 in the suction port 6 is gripped with a finger, pulled toward the user, and removed by hand. Can be. Alternatively, by rotating the rotating brush 3, as shown in FIG. 13, the leading end portion of the sheet comes into contact with the leading end 5 d of the cover 5 and is peeled off, and the sheet 12 can be removed from the rotating brush 3 by being unwound.
[0043]
Here, when removing the seat 12, as described above, the cover 5 is opened and closed up and down to form the front wall of the suction tool main body case 2, so that the seat 12 can be easily taken out. That is, the cover 5 is normally closed by a spring or the like, but as shown in FIG. 9, when the cover 5 is manually moved upward so as to be housed inside the main body case and opened like a shutter, the suction port 6 is closed. It changes from a small opening where it is difficult to take out the bottom only before the opening operation to a large opening that also opens the front. For this reason, it becomes easy to touch the sheet 12 with the opening 6b of the front part, and the sheet 12 can be picked up and easily taken out.
[0044]
When the sheet 12 is wound around the rotating brush 3, it is convenient if the wound state can be easily confirmed. FIGS. 11 and 12 show an appropriate structure for confirming the winding state. In the case of FIG. 11, the front portion of the suction device main body case 2 is formed of a transparent member so as to be a transparent portion 12A, and in FIG. A hole 24, in this case, a pair of viewing holes 24, 24 is provided on the left and right. Here, the peephole 24 may be a transparent window covered with a transparent member so that dust does not enter. With these configurations, it is possible to determine whether the sheet 12 has been wound properly. If the winding is not good, it is possible to immediately take measures to obtain the desired wiping effect by re-winding and mounting normally.
[0045]
FIG. 15 and FIG. 16 show a sheet which is shaped so that the end of the sheet 12 wrapped around the rotating brush 12 is exposed and the noise generated on the floor surface is suppressed. In FIG. 15, the rear end of the sheet 12 is cut obliquely to form a triangular shape, and in FIG. 16, the rear end of the sheet 12 is cut into an M shape.
[0046]
When a general rectangular sheet is wound and operated, the rear part (end of the end of the sheet) of the sheet is exposed, and the sheet end is sucked into the suction port, thereby generating abnormal noise. On the other hand, when the tip is triangular or M-shaped like the sheet 12, the sheet end pieces 12b, 12c, and 12c are the front portions having a small contact area with the floor or the case (suction device main body case). Since the phenomenon of hitting the floor surface at the end as in the case of the conventional rectangular sheet is eliminated, the occurrence of abnormal sound is suppressed. In addition, it is possible to prevent the sheet edge from fluttering.
[0047]
FIGS. 17 to 19 show a configuration according to another embodiment that enables the sheet 12 to be further securely wound around the rotating brush 3 and mounted. When the tip of the sheet 12 is simply hooked on the rotating brush 3 and wound, the front edge of the sheet may be crimped and pulled in, and the winding may not be uniform.
[0048]
In order to cope with this, in FIG. 17, a string 25 is provided at the front end (winding start end) of the sheet 12 by sewing or bonding. In this case, as shown in FIG. 18, the string 25 is entangled with an arbitrary brush body 8 of the rotating brush 3, whereby the sheet 12 can be reliably wound in order from the front end.
[0049]
In the case of FIG. 19, a hard material such as a wire 26 is sewn to the sheet 12, and the tip (the winding start end) is formed in a hard structure, that is, the hardened edge 27. With this configuration, when the sheet is mounted, the front end of the seat is not crumpled by the wire 26 or the like being taut by the wire 26 or the like, so that the rotary brush 3 can be mounted uniformly. Thereby, stable winding can be performed.
[0050]
Further, in the case of FIG. 20, the loop of the string 28 is provided on both sides of the front end of the seat 12. On the other hand, a hook 29 on which the loop of the string 28 is hooked is formed on the core 7 toward the rotating brush 12. With this configuration, as shown in FIG. 21, the loop of the string 28 is hooked on the hook 29, so that the hook 29 can be mounted uniformly from the front end. Thereby, similarly, stable winding can be performed. In addition, the end of the sheet 12 can be fixed to the core of the rotating brush 3 using a removable tape.
[0051]
With the configuration in which the locking means is provided at the tip of the sheet 12, the front edge of the sheet 12 can be wound around the rotating brush 3 in a uniform and stable state without crumpling.
[0052]
As described above, the shape of the sheet 12 is changed, or the sheet 12 is easily wound by providing a means for attaching to the rotating brush 3, but the brush body (blade) 8 of the rotating brush 3 is shown in FIGS. In the case of a one-way spiral shape as shown in FIG. 20, as the sheet 12 is wound or the operation is continued after winding, the sheet 12 may be biased to one side and the wiping effect and the floor polishing effect may be reduced. .
[0053]
In order to deal with this point, when providing the brush body (blade) 8 on the peripheral surface of the core body 7, as shown in FIG. 28, when the core body 7 is viewed horizontally, the brush body (blade) 8 becomes V-shaped. It is good to arrange it in a shape like a circle. That is, the brush body (blade) 8 may be formed so as to be wound around the core body 7 in one direction obliquely toward the center in the longitudinal direction of the shaft, and to be folded back from the center part and wound around the core body 7 in the opposite direction. .
[0054]
With this configuration, the sheet 12 wound around the surface of the brush body 8 receives a contact resistance from the V-shaped arrangement of the brush body 8 due to the rotation of the rotary brush 3, but the sheet 12 is mutually separated as a resistance component. The force in the stretching direction is generated on the left and right. This prevents a problem that the sheet 12 shifts to one side and starts to bias. Therefore, even during rotation, the sheet 12 is wound and maintained at the proper position, and the wiping and cleaning effects can be sufficiently obtained.
[0055]
FIG. 29 shows a configuration in which a guide rib 30 that exerts a similar sheet stretching action is provided on the main body case 2 side. In this case, a guide rib 30 is formed on the inner wall surface 2D of the main body case 2 (upper case 2a) so as to surround the upper part of the brush and follow the rotation locus thereof. The guide ribs 30 are arranged and formed in a V-shape such that the guide ribs 30 open in both sides from the center in the longitudinal direction of the rotating brush 3. The guide rib 30 is formed to have a length such that its tip projects so as to come into contact with the sheet 12 wound around the rotating brush 3. The sheet 12 is guided by the guide ribs 30 provided in such a form, and a contact force generated when the sheet 12 comes into contact with the sheet 12 generates a component force acting in the direction of stretching the sheet 12. As a result, not only when the rotating sheet 12 is wound, but also after the winding, the sheet 12 is maintained in a pinned state, and at the same time, the sheet 12 does not shift sideways on the core body 7 and is wound to a regular position. Will be retained. For this reason, the same wiping cleaning and polishing effects as when the brush body 8 is arranged in a V-shape can be obtained.
[0056]
The floor suction device 1 of the present embodiment having the above-described configuration is used for cleaning a tatami mat, a carpet, or the like, using a vacuum cleaner without the sheet 12 attached, scraping dust with the rotating brush 3, and sucking the dust from the suction port. To clean. On the other hand, when cleaning the floor surface such as flooring, the sheet 12 is wound around the rotating brush 3, and the floor surface is wiped and cleaned by the sheet 12 which rotates integrally with the brush, so that the floor polishing effect is also achieved, so that the cleaning is effectively performed. it can.
[0057]
【The invention's effect】
As described above, according to the present invention, the rotating brush that is housed inside the suction tool so as to face the suction port on the lower surface and is driven to rotate can automatically wind the suction sheet having the dust adhesion property with the rotation. Because of this structure, the seat can be easily attached, and the floor can be immediately wiped and cleaned.
[0058]
Also, the wrapping of the sheet is such that bristle brushes with different bristle lengths and hardness and mixed bristle brushes are arranged evenly around the core of the rotating brush, and these are configured to bend according to the sheet, so the sheet Can be attached in a state of being stretched round and non-distorted, and can sufficiently exert a wiping effect and a polishing effect. In addition, since the bristle brush is arranged evenly around the brush, the root of the brush that bends along the sheet does not bend extremely to the root like a brush with a sparse arrangement, so the brush's original dust removal performance Can be maintained.
[0059]
In particular, the brush is a combination of a long, soft brush on the outside and a short, hard brush on the inside, which is provided as one of the brush bodies. In this state, it can be wound and held around the rotating brush.
[0060]
In addition, a rib is interposed between the brush bodies arranged on the rotating brush so as to extend to the root of the brush body so as to fill the space between the brush bodies. Deformation can be prevented.
[0061]
Further, the front wall of the main body case is formed of a cover which can be opened and closed in a vertical direction, and the suction port can be opened in front, so that the seat can be easily removed.
[0062]
Further, since the sheet can be inserted and mounted using the gap between the roller and the cover surface provided at the front end of the cover and configured to buffer the contact with the wall surface at the time of cleaning, the sheet is provided with a roller. Guides smoothly, and is securely wound. Also, the work of mounting the seat becomes easy.
[0063]
Further, since a resistance member such as a raised cloth is provided on the outer peripheral surface of the roller, the contact resistance with the sheet increases, and the sheet can be fed more reliably without slipping.
[0064]
Further, since the cover is formed of a transparent material or provided with a viewing window, the winding state of the sheet can be checked, and if the winding method is not normal, it is possible to immediately respond to a correction operation such as re-winding.
[0065]
In addition, by using a sheet having a triangular or M-shaped rear shape as a sheet, the rear end of the sheet, which is exposed after winding, can have a small contact portion with the floor surface, thereby reducing noise. Generation can be suppressed.
[0066]
At the front end of the seat, a locking member for engaging with the rotating brush is provided. For example, by attaching a string or sewing a wire or the like at the front end and forming it on a hard edge, the sheet can be easily attached to the rotating brush, and the sheet is wound around without crumpling the tip of the sheet It is economical because sheets are not wasted.
[0067]
Similarly, even with a configuration in which the string provided on both sides of the front end of the sheet and the hook portion on which the loop of the string provided on the rotating brush is hooked, the tip of the sheet is not crumpled, Can be wound.
[0068]
Also, unlike the conventional spiral shape, the rotating brush is arranged in a V-shape when the core is viewed horizontally, so that the sheet wound by this arrangement is accompanied by the contact rotation of the brush. The force in the sheet stretching direction acts, and the problem that the sheet wound around the conventional spirally arranged brush body is not biased is eliminated. Therefore, the sheet can be maintained in a uniform wound state even during rotation, and the desired wiping effect and polishing effect can be obtained.
[0069]
Further, a guide rib having a shape along the rotation locus of the rotating brush is provided inside the main body case, and the guide rib is arranged in a V-shape which is opened in the axial direction on the core body. Since a force is generated in the direction in which the sheet is stretched, it is possible to obtain a uniform seat mounting and the desired wiping and polishing effects as in the case of the V-shaped brush body.
