The present invention relates to a cleaning tool.
DESCRIPTION OF RELATED ART Conventionally, there exists a thing of patent documents 1, 2 as a cleaning tool which collects fiber refuse, such as hair and cotton dust which exist in the fiber which comprises a carpet.
The cleaning tool described in Patent Document 1 has a shaft portion that is fine but rigid on the surface of a sheet or roller that is slid or rotated on a carpet, and a lump-shaped tip portion that is thicker than the shaft portion, or a curved or curved surface. A protrusion having a refracted tip is densely protruded at a small interval, and has a cleaning member in which an adhesive layer is embedded between the protrusions. Adhesive material layer in which protrusions bite into the fibers of the carpet, fiber dust present in the fibers is captured at the tip of the protrusions, and is extracted from the carpet, and the garbage extracted from the carpet is embedded between the protrusions. It is surely collected and held by.
The cleaning tool described in Patent Document 2 is composed of a brush-like member composed of a bristle portion having flexibility and elasticity, and a nonwoven fabric, and the nonwoven fabric is embedded in the member having the brush-like shape. Configured. By moving the brush-like member back and forth on the carpet, the fiber dust present in the carpet fibers is captured by the brush-like member and the carpet fiber dirt is adsorbed by the nonwoven fabric. .
As another conventional cleaning tool, there is one that adsorbs garbage and dirt on the carpet by an adhesive sheet on the surface of an adhesive roll that rolls on the carpet.
In the cleaning tool having the cleaning member described in Patent Document 1, the tip of the protrusion that has digged into the fibers of the carpet collects only the fiber dust extracted from the fibers of the carpet in the adhesive layer. Only. It is only possible to capture the fiber dust that happens to be in the part of the carpet fiber where the protrusion has bite, and the protrusion can be removed from the carpet. Moreover, it is necessary to hold the fiber dust captured by the protrusions with the pressure-sensitive adhesive layer. When the adhesive force is lost, it cannot be collected. Therefore, the collection performance of fiber waste is poor.
And in the cleaning tool of patent document 1, when a protrusion is provided on the surface of the roller, the roller only rolls on the carpet, and does not operate such that the protrusion moves relative to the carpet and combs. . At this time, the protrusion sticks into the carpet hair and comes out of the stuck portion, but the fiber waste lies on the carpet surface and entangles with the carpet hair over its length, and further the carpet hair. Since it sticks to the surface with static electricity, it cannot be picked up by picking up fiber dust at the tip of the projection which is curved. Therefore, the collection performance of fiber waste on the carpet is low.
Moreover, in the cleaning tool described in Patent Document 1, an adhesive layer is embedded between protrusions to improve the collection performance of fiber dust. However, the pressure-sensitive adhesive layer tends to lose its adhesive force unexpectedly quickly because dirt dust or fine fibers of the carpet adhere to the surface, and it is difficult to improve the collection performance.
Moreover, in the cleaning tool of patent document 1, although the hook part of refraction etc. is provided so that the front-end | tip part of a protrusion may catch fiber waste easily, this is a double-edged sword and makes it easy to catch fiber waste. On the other hand, the resistance when pulling out the tip of the protrusion from the carpet increases, and the operating force increases. When the projection provided on the surface of the sheet is slid on the carpet for cleaning, the curved tip of the projection enters the hair of the carpet and is dragged while being caught, so the operating force becomes very heavy. . Further, when cleaning a loop carpet having a carpet hair end rounded into a loop shape, a curved tip end of the protrusion is caught on the carpet loop end hair, which damages the carpet hair.
Moreover, in the cleaning tool of patent document 1, about the removal of the collected garbage, if the above-mentioned adhesive layer is comprised with water solubility, it is supposed that the collected garbage can be easily removed by water washing. However, textile waste, which is the main waste of carpet, is entangled with protrusions and is firmly wound around the roller body, and it is not easy to remove it.
In the cleaning tool having the brush-like member described in Patent Document 2, the fiber dust existing in the carpet fibers is merely captured by the brush-like member that is moved back and forth on the carpet. The collection performance of fiber waste is poor.
Moreover, in the cleaning tool described in Patent Document 2, since the entire cleaning surface of the main body provided at the tip of the handle of the cleaning tool has a brush portion and receives resistance on a wide surface, the operation force becomes very heavy. Moreover, when the base position of the handle in the cleaning tool is used as a reference, a large resistance is applied to the brush portion positioned on the front side in the cleaning progress direction. For this reason, when the handle and the main body are connected by a universal joint, the main body takes a posture to be picked up and cannot be operated. Therefore, the handle and the main body must be fixed at a certain angle like a deck brush, and there is a drawback that it is difficult to handle.
In a cleaning tool having an adhesive roll that rolls on the carpet, the adhesive sheet on the surface of the adhesive roll can adsorb only dust on the surface of the carpet, and cannot capture fiber dust present in the fibers of the carpet. There is also a possibility that carpet fibers may be peeled off due to the adhesive force of the adhesive roll. Also, if dirt dust or the like adheres to the adhesive roll or fiber dust is adsorbed and loses its adhesive strength, the collection life will be lost, and several adhesive sheets on the surface of the adhesive roll are usually updated to clean one room. This is uneconomical and time consuming.
An object of the present invention is to efficiently collect fiber dust and wipe off dirt and the like with a simple cleaning tool.
The invention according to claim 1 is a cleaning tool having a cleaning roll that can freely rotate in one direction on the cleaning head and that has a braking force in the reverse direction . A raised pile provided with raised hairs is provided, and the short fibers of the nonwoven fabric are entangled around the raised hairs of the raised pile .
ADVANTAGE OF THE INVENTION According to this invention, while collecting fiber waste efficiently with a simple cleaning tool , dirt dust etc. can be wiped off .
The cleaning tool 10 shown in FIGS. 1 to 4 has a carpet, a floor of flooring, etc. as a surface to be cleaned, fiber waste (hair, cotton dust, etc.), grain dust (rice, confectionery waste, soil dust) on the surface to be cleaned. , Sand, etc.), and dirt such as dirt is wiped off. The cleaning tool 10 has a dust container 40 in a cleaning head 30 provided at the tip of the handle 20, front and rear side openings 41 (41 F, 41 R) provided in front and rear of the dust container 40, and those It has cleaning rolls 50 (50F, 50R) before and after closing the side opening 41.
In the cleaning tool 10 of the present embodiment, the cleaning roll 50 is rolled on the surface to be cleaned by the operating force applied to the handle 20, and the direction in which the cleaning head 30 advances by the pressing operation force applied to the handle 20 is forward (see FIG. 2), and the direction in which the cleaning head 30 advances by the pulling operation force applied to the handle 20 is the rear direction (R direction in FIG. 3).

The pin 27 is inserted between the pins 32 and 32 and is fixed to the pin 27 fixed to the support portion 32. The pin 27 extends in the left-right direction of the cleaning head 30, and the bush 26 is disposed orthogonally to the pin 27. Thus, the user can swing the handle 20 left and right around the bush 26 and swing the handle 20 back and forth around the pin 27.
As shown in FIGS. 2 and 3, the handle 20 is loaded with the coil spring 28 in a state of being contracted from the free state in the center hole 21 </ b> A of the rod-like body 21 at the tip, and the repulsive force of the coil spring 28 is expected to extend. The slider 28A loaded in the center hole 21A is pressed against an arc surface 24A (an arc surface centered on the bush 26) provided on the connecting plate 24 of the joint 23, so that the handle 20 freely swings around the bush 26. Braking to move. Further, a central hole 34A provided in a boss 34 (described later) of the upper frame 31U of the cleaning head 30 and opened to the upper surface is loaded in a state where the coil spring 29 is contracted from the free state, and the central hole pressed by the coil spring 29 is also used. The slider 29A loaded in 34A is pressed against an arc surface 23A (an arc surface centered on the pin 27) provided in the joint 23 to brake the handle 20 from freely swinging around the pin 27. ing. As a result, the user grasps the handle 20 and lifts the entire cleaning tool 10 from the surface to be cleaned, and moves the entire cleaning tool 10 in its original posture without changing the relative angular posture of the handle 20 and the cleaning head 30. Can be posted.
As shown in FIGS. 2 and 3, the cleaning head 30 includes a combined body of an upper frame 31U and a lower frame 31L.
The upper frame 31U extends across the entire area of the cleaning head 30 in the front-rear and left-right directions, and arc-shaped cover portions provided at both ends in the front-rear direction cover substantially the upper half circumference of the front and rear cleaning rolls 50. The upper frame 31U is provided with a central rib 33 that is suspended at the center in the front-rear direction on the lower surface of the upper frame 31U so as to extend across the entire region in the left-right direction intersecting the left and right side walls of the upper frame 31U. A boss 34 having a central hole in which the above-described coil spring 29 is loaded is protruded downward at a central portion in the left-right direction of the central rib 33 on the lower surface of the upper frame 31U.
The lower frame 31L has a frame shape that is fitted between the left and right side walls of the upper frame 31U. As shown in FIG. 5, the lower surface of the rectangular outer peripheral frame 35 is a horizontal plane that can be in sliding contact with the surface to be cleaned. The lower surface of the frame 35 is provided with a step surface 36 having a step depth equivalent to the thickness of the slide-type bottom plate 43, and both front and rear edges 43A of the bottom plate 43 are fitted from the left and right sides to the front and rear side walls sandwiching the step surface 36. It has the groove part 36A to obtain. The lower surface of the bottom plate 43 fitted in the groove portion 36A of the lower frame 31L is flush with the lower surface of the outer peripheral frame 35 and can come into sliding contact with the surface to be cleaned.
The lower frame 31L includes a central rib 37 in the plane of the step surface 36 provided in the outer peripheral frame 35. The central rib 37 is erected at the central portion in the front-rear direction in the outer peripheral frame 35 and extends across the entire region in the left-right direction along the front and rear groove portions 36 </ b> A of the outer peripheral frame 35. The lower surface of the central rib 37 is flush with the step surface 36. Note that a guide groove portion 36B into which the central convex guide 43B of the bottom plate 43 can be fitted is also provided on the lower surface of the central rib 37 of the outer peripheral frame 35.
The lower frame 31L includes a plurality of parallel bars 38 between the front and rear side walls sandwiching the step surface 36 of the outer peripheral frame 35 and the central rib 37. The lower surface of the crosspiece 38 is flush with the stepped surface 36 and the lower surface of the central rib 37. The upper surface of the crosspiece 38 forms a downwardly inclined curved inclined surface 38 </ b> A extending from the upper portion of the central rib 37 toward the upper portion of the outer peripheral frame 35. Note that the cross section of the crosspiece 38 has a substantially triangular cross section with a narrow upper surface, so that the cleaning roll 50 can easily drop the dust thrown down as described later.
The lower frame 31L has screws 39 inserted from a plurality of positions on the lower surface of the central rib 37 in a state where the upper end concave portion 37A of the central rib 37 is fitted to the lower end convex portion 33A of the central rib 33 of the upper frame 31U. By being screwed to the lower surface mounting portion, the upper frame 31U is coupled.
Thus, the cleaning head 30 is connected to the upper frame 31U in a state where the upper frame 31U and the lower frame 31L are coupled, and the bottom plate 43 is fitted in the groove portions 36A and 36B provided in the step surface 36 on the lower surface of the lower frame 31L. A dust container 40 is formed between the lower frames 31L. The dust container 40 is divided in the front-rear direction by the center rib 33 of the upper frame 31U and the center rib 37 of the lower frame 31L at the center in the front-rear direction of the cleaning head 30. The cleaning head 30 has front and rear dust storage portions 40F, 40R, the front dust storage portion 40F includes a side opening 41F that opens to the front, and the rear dust storage portion 40R opens to the rear. An opening 41R is provided.
The cleaning tool 10 is a dust invitation surface portion that guides dust from the surface to be cleaned to the side surface opening 41 along the lower end of the side surface opening 41 (41F, 41R) provided in the dust container 40 (40F, 40R) of the cleaning head 30. 42 is provided. The outer surfaces of the front and rear outer peripheral frames 35 of the lower frame 31L of the cleaning tool 30 are in sliding contact with the outer periphery of the cleaning roll 50 over the entire length of the cleaning roll 50, or a small gap is provided on the outer periphery of the cleaning roll 50. The front and rear dust invitation surface portions 42F and 42R are arcuate. The lower edge 42A of the dust invitation surface portion 42 (42F, 42R) intersecting at an acute angle with the lower surface of the outer peripheral frame 35 comes into close contact with the surface to be cleaned and moves in contact with the surface to be cleaned. Scoop up the garbage onto the garbage invitation surface 42. The upper end edge 42B of the dust invitation surface portion 42 also forms an acute angle, and when the cleaning roll 50 rotates toward the upper end edge 42B (for example, when the cleaning tool 10 moves forward (direction F in FIG. 2), the cleaning tool 10 around the cleaning roll 50R in FIG. 3 positioned behind (the R direction in FIG. 3), the dust in the dust container 40 (40R) is less likely to enter the pressing roll 50 (50R) from the upper edge 42B. Yes.
As shown in FIGS. 1 and 4, the cleaning tool 10 supports both ends of the front and rear cleaning rolls 50 (50F, 50R) on the front and rear sides of the left and right side walls of the cleaning head 30 (upper frame 31U). To do. Thereby, the cleaning tool 10 arranges the two front and rear cleaning rolls 50 (50F, 50R) in parallel with each other and arranges them on the cleaning head 30 so that their lower surfaces can be rotated inward. The dust container 40 (40F, 40R) is disposed at a position between the two.
At this time, the cleaning roll 50 is supported in a state where the cleaning head 30 can freely rotate in one direction and is locked in rotation (or rotates slowly) by applying a braking force in the opposite direction. That is, the cleaning roll 50 is inserted into a support shaft 61 that is screwed and fixed to one of the left and right side walls of the upper frame 31U of the cleaning head 30 via a collar 62 that is fixed by press-fitting or the like to one end side of the core 51 described later. The support shaft 63 is pivotally supported and freely screwed to the other side wall of the upper frame 31U. The support shaft 63 is loaded on the other end of the core 51 in one direction via a one-way rotating tool 70. Is freely rotatable, and is supported in a state where it is rotationally locked (or rotated slowly) by a braking force acting in the opposite direction.
Here, the structure in which the cleaning roll 50 can freely rotate in one direction and is rotationally locked in the opposite direction depends on the structure of the one-way rotating tool 70 described later.
The structure in which the cleaning roll 50 can freely rotate in one direction and rotates slowly in the opposite direction is, for example, the left and right support shafts 61 and 63 of the cleaning roll 50 on the left and right side walls of the upper frame 31U of the cleaning head 30. On the other hand, it is supported via back and forth play (or a long hole). When the cleaning head 30 moves forward (F direction in FIG. 2), the cleaning roller 50R on the rear side is the upper frame among the cleaning rollers 50F and 50R that move forward and backward with respect to the upper frame 31U. It is braked against a rough surface (or a brake member that generates frictional resistance such as rubber material) provided at the rear of 31U, and slowly rotates while rubbing the surface of the cleaning roll 50 against the surface to be cleaned. Conversely, when the cleaning head 30 advances in the rearward direction (R direction in FIG. 3), the front side cleaning roll 50F is the upper one of the front and rear cleaning rolls 50F, 50R that move forward by the amount of play relative to the upper frame 31U. It is braked against a rough jagged surface (or brake member) provided at the front of the frame 31U, and rotates slowly.
As shown in FIGS. 6 and 7, the unidirectional rotating tool 70 includes a fixed shaft 71, a rotating cover 72, a coil spring 73, and a piece 74. The fixed shaft 71 includes a flange portion 71B at one end of the shaft portion 71A, and includes a hole 71C inserted into the support shaft 63 protruding inside the left and right side walls of the upper frame 31U. A non-rotating convex portion 71D that is engaged with a recess provided on the side wall of the frame 31U and prevents the fixed shaft 71 from rotating with respect to the upper frame 31U is provided on the outer end surface of the flange portion 71B. The rotary cover 72 includes a flange portion 72B at one end of the hollow shaft portion 72A attached to the shaft portion 71A of the fixed shaft 71, and the hollow shaft portion 72A is attached to the shaft portion 71A of the fixed shaft 71. In the assembled state with the fixed shaft 71 with the flange portion 72B abutted against the flange portion 71B of the hollow shaft portion 71A, the hollow shaft portion 72A is locked in an annular groove provided in the shaft portion 71A of the fixed shaft 71 protruding from the opening 72E at the bottom of the other end. The C-shaped clip 75 is retained from the shaft portion 71A of the fixed shaft 71. The one-way rotator 70 press-fits the hollow shaft portion 72A of the rotary cover 72 in an assembled state with the fixed shaft 71 to the other end side of the above-described core 51 of the cleaning roll 50, and the outer periphery of the hollow shaft portion 72A. The rotation-preventing convex portion 72 </ b> C provided on the center core 51 is engaged with the recess provided in the core 51, and the rotation cover 72 is prevented from rotating with respect to the core 51. In the assembled state of the fixed shaft 71 and the rotary cover 72, the one-way rotating tool 70 is loaded with a coil spring 73 and a piece 74 around the shaft portion 71A of the fixed shaft 71 from the opposite side of the flange portion 71B. The slide groove 74A of the piece 74 is engaged with the provided slide convex portion 71E so as to be slidable in the axial direction. Accordingly, the claw 74B on the front end surface of the piece 74 that is prevented from rotating by the shaft portion 71A of the fixed shaft 71 and is axially pushed by the coil spring 73 and slides to the claw 72D on the inner bottom surface of the other end of the rotary cover 72. Engage.
By being configured as described above, in the one-way rotator 70, the rotary cover 72 that is press-fitted and fixed to the core 51 of the cleaning roll 50 is fixed in the N1 direction (forward direction) in FIG. As it rotates, the piece 74 is pushed by the spring 73 along the upward slope of the claw 72D of the rotary cover 72, and gradually moves from the original position in the axial direction to the one side. When the highest point of the upward slope is exceeded, it snaps back and returns to the original position in the axial direction. When the rotation cover 72 and the claws 72D and 74B of the piece 74 are provided at intervals of 180 degrees in the circumferential direction, the above-described operation is repeated every rotation of the rotation cover 72 by 180 degrees and the rotation cover 72 rotates in the N1 direction. In the unidirectional rotating tool 70, the fixed shaft 71 is actually fixed to the upper frame 31U, and the rotary cover 72 rotates. However, FIG. 8 rotates the pattern of relative rotation between the fixed shaft 71 and the rotary cover 72 in a display relationship. The cover 72 is shown stationary. On the other hand, when the rotary cover 72 tries to rotate in the N2 direction (reverse direction) in FIG. 7, the claw 72D of the rotary cover 72 is hooked on the claw 74B of the piece 74 and locked.
Therefore, in the cleaning tool 10 having the two front and rear cleaning rolls 50 (50F, 50R), when the cleaning head 30 advances in the front direction (the F direction in FIG. 2), the front side cleaning roll 50F rotates. The rear cleaning roll 50R is rotationally locked. Conversely, when the cleaning head 30 advances in the backward direction (R direction in FIG. 3), the front cleaning roll 50F is rotationally locked, and the rear cleaning roll 50R rotates.
When viewed from the lower surface of the cleaning head 30, the cleaning head 30 enables the front and rear cleaning rolls 50 </ b> F and 50 </ b> R to rotate only in the inward direction (the dust invitation surface portion 42 and the dust storage portion 40 side). That is, the front dust invitation surface portion 42F and the dust storage portion 40F are arranged downstream of the rotation direction of the front cleaning roll 50F with respect to the surface to be cleaned, and downstream of the rotation direction of the rear cleaning roll 50R with respect to the surface to be cleaned. A rear dust invitation surface portion 42R and a dust storage portion 40R are arranged on the side. The cleaning roll 50 (50F, 50R), which rotates as the cleaning head 30 moves forward or backward, holds the dust between the surface to be cleaned and removes the dust from the dust invitation surface portion 42 (42F, 42R). It is taken into the garbage container 40 (40F, 40R).
As shown in FIG. 9, the cleaning roll 50 has a center core 51 as a roll shaft made of a metal pipe such as a paper tube, a hard plastic pipe, and aluminum, and the sponge roll 52 is formed on the entire periphery and the entire length of the outer periphery of the center core 51. A cylindrical raised pile 53 is detachably provided on the outer periphery of the sponge roll 52, and a large number of fine raised portions 54 of the raised pile 53 are provided as protrusions on the outer peripheral surface of the sponge roll 52. At this time, the cleaning roll 50 is inclined or curved so that the tip (hair tip) of the raised hair 54 faces the rotation direction of the cleaning roll 50. Here, the sponge roll 52 may be made of other soft materials such as rubber, thermoplastic elastomer, and urethane gel.
As shown in FIG. 10, the raised pile 53 is formed by raising raised portions 54 made of a part of the mesh fabric 53A at various points of the lattice-like mesh fabric 53A forming a large number of meshes. Such a raised pile 53 is produced by cutting each middle thread of a pile made up of, for example, a mesh fabric on the front and back knitted by a double raschel knitting machine and a plurality of medium yarns connecting the mesh fabric on the front and back into half. It is comprised by the raising | fluff 54 which consists of the mesh fabric 53A of the front side or back side which is, and the half part of the middle thread connected to those mesh fabrics 53A.
As shown in FIG. 9, the raised pile 53 is formed in a cylindrical shape having an inner diameter smaller than the free roll diameter of the sponge roll 52 constituting the cleaning roll 50. Such a cylindrical raised pile 53 reduces the roll diameter of the sponge roll 52 from the free state and receives the elastic restoring force of the reduced-diameter sponge roll 52 on the outer circumference of the sponge roll 52. It is closely attached. The material of the raised pile 53 (the mesh fabric 53A and the raised 54) is made of, for example, polyester fiber, and has a hair thickness of 30D and a raised hair length of 2 mm. As a result of comparing the lengths of raised brushes of 0.5 to 2 mm, it was confirmed that a length of 2 mm was suitable because the cleaning operation resistance was large and the amount of collected dust was small. The material, thickness, and length of the raised hair 54 can be used for cleaning on the same principle even if there are some effects other than those described here. It is also possible to select an appropriate one according to the type of carpet to be cleaned and the type of garbage.
As shown in FIG. 9, the cleaning roll 50 includes a large number of raised brushes 54 protruding from the surface layer made of the wiping cloth 55. In the present embodiment, a nonwoven fabric 56 is provided in advance around the raised portions 54 of the cylindrical raised pile 53 described above, and this nonwoven fabric 56 is used as a wiping cloth 55.
Therefore, according to the cleaning tool 10, a cleaning operation is performed as follows. In addition, the surface to be cleaned can be cleaned up to the wall side by providing the cleaning roll 50 and the dust invitation surface portion 42 over the entire possible width of the upper and lower frames 31U and 31L of the cleaning head 30.
(a) When the cleaning head 30 of the cleaning tool 10 moves in one direction and advances the cleaning head 30 in a direction in which one cleaning roll 50 is rotationally locked, a large number of raised brushes 54 on the lower surface side of the non-rotating cleaning roll 50 are carpeted. In the state of being stabbed in the fiber of the fiber, it is moved by dragging, scraping the fiber litter 1 such as hair and cotton dust present in the fiber of the carpet, and hooking it. Next, when the cleaning head 30 moves in the opposite direction and proceeds in the direction in which the one cleaning roll 50 rotates, the fiber litter 1 that has been collected by being caught by the numerous raised portions 54 on the lower surface side of the cleaning roll 50 is removed. It is pulled around the surface layer of the roll 50 and wound up and collected while being entangled with the numerous raised portions 54. Thus, by collecting only one of the cleaning rolls 50 and rotating and locking the other, the collection performance of the fiber dust 1 is significantly improved.
The cleaning roll 50 can be applied not only to the carpet but also to the flooring, and the fiber dust 1 on the flooring can be collected in the same manner as described above by the raising 54 of the cleaning roll 50.
In a state where a large number of raised portions 54 of the cleaning roll 50 are stuck in the fiber of the carpet, the fiber dust 1 in the fiber is entangled and wound around the surface layer of the cleaning roll 50 and collected. Therefore, the adhesive force is not used, and the fibers constituting the carpet are not peeled off.
Moreover, the raising 54 of the cleaning roll 50 can wind up the fiber dust 1 so as to pull it around the surface layer of the cleaning roll 50, and the fiber dust 1 can be stacked in many layers to collect a large amount. As long as there is a protruding portion of the raised bristles 54 protruding from the surface of the cleaning roll 50, the fiber litter 1 can be collected, and the collection performance is not lost even if the space between the six tatami mats where the pet is present is cleaned for one week.
In the cleaning tool 10, when a large amount of fiber dust 1 is wound around the surface of the cleaning roll 50 and collected, the raised pile 53 and the nonwoven fabric 56 are removed from the outer periphery of the sponge roll 52 of the cleaning roll 50. Thereby, the collected fiber waste 1 can be easily removed together with the raised pile 53 and the nonwoven fabric 56.
(b) Since the cleaning roll 50 has the raised end 54 pointed in the rotation direction of the cleaning roll 50, the above-described (a) scraping and catching effect of the raised dust 54 of the cleaning roll 50 is locked. Can be improved.
(c) The cleaning head 30 arranges the dust invitation surface portion 42 and the dust container 40 on the downstream side of the rotation direction with respect to the cleaning surface of the cleaning roll 50, so that the rotating cleaning roll 50 is cleaned on the carpet or flooring surface to be cleaned. Grain dust 2 and the like sandwiched between the two can be taken into the dust container 40 from the dust invitation surface 42 and collected.
(d) When the cleaning roll 50 is formed with a surface layer having the raised portions 54 on the outer periphery of the sponge roll 52, the cleaning roll 50 is adapted to bite the particle dust 2 or the like on the surface to be cleaned of the carpet or the flooring. 52 is deformed and moved on the surface to be cleaned while the dust particles 2 and the like that have been caught are pressed onto the surface to be cleaned, and the particle dust 2 and the like are scraped up to the downstream side of the rotation of the sponge roll 52 so as to attract dust. Can be collected in the garbage container 40.
The dust particles 2 and the like that have sunk into the sponge roll 52 are drawn into the dust invitation surface portion 42, and are further squeezed and slid up on the dust invitation surface portion 42. It is thrown into the waste container 40 from the section 41.
(e) The cleaning roll 50 has a large number of raised hairs 54 protruding from the surface layer made of the wiping cloth 55 (nonwoven fabric 56). The surface wiping cloth 55 and the raised bristles 54 of the cleaning roll 50 that has been rotationally moved are dragged and moved on the surface to be cleaned of the carpet or flooring to wipe off dirt such as dirt on the surface to be cleaned. When cleaning flooring, if dirt remains, the cleaning effect is felt thin, which is important.
(f) The cleaning head 30 arranges the two front and rear cleaning rolls 50F and 50R in parallel with each other, the bottom surfaces of the cleaning heads 50F and 50R can be rotated inward, and the dust container 40 ( 40F, 40R). When the cleaning head 30 is advanced in one direction, one of the cleaning rolls 50R is rotationally locked, and the fiber dust 1 is hooked on the raised bristles 54, and the dirt of dirt and dirt is wiped off by the surface wiping cloth 55 of the cleaning roll 50R. The other cleaning roll 50F is rotated and the fiber dust 1 that has already been caught by the raised bristles 54 is wound around the surface layer of the cleaning roll 50F and collected, and the granular dust 2 and the like are scraped up and collected in the dust container 40F. Can be collected.
Further, among the front and rear cleaning rolls 50F and 50R with respect to the joint 23 of the handle 20 and the cleaning head 30, for example, when moving forward, only the rear cleaning roll 50R is stopped and the front cleaning roll 50F is freely rotated. Therefore, the moment balance around the joint 23 acting on the cleaning head 30 is improved. That is, in FIG. 2, the rear cleaning roll 50 </ b> R receives a backward force from the cleaning surface, and exerts a counterclockwise moment around the joint 23 to the cleaning head 30. On the other hand, since the front cleaning roll 50F rotates freely, it receives only a vertical force from the cleaning surface and exerts a clockwise moment around the joint 23 to the cleaning head 30. Since these two moments are balanced, even if a horizontal force is applied from the handle 20 to the joint 23, the cleaning head 30 does not pick up.
Next, by moving the cleaning head 30 in the other direction, one cleaning roll 50R is rotated, and the fiber dust 1 already caught on the raising 54 is wound around the surface layer of the cleaning roll 50R and collected. In addition, the dust particles 2 and the like are scraped up and collected in the dust container 40R, the other cleaning roll 50F is rotationally locked, the fiber dust 1 is hooked on the raised hair 54 and dragged, and the surface cloth of the cleaning roll 50F is wiped By 55, dirt such as soil dust is wiped off.
Accordingly, in both of the movements of the cleaning head 30 in both directions, the collection of the fiber dust 1, the collection of the grain dust 2, etc., and the wiping of dirt such as soil dust are performed.
Hereinafter, the manufacturing method of the cylindrical raising pile 53 with the above-mentioned nonwoven fabric 56 is demonstrated. This is because the nonwoven fabric 56 is formed around the raised fiber 54 around the raised pile 54 of the mesh fabric 53A to form the nonwoven fabric 56 around the raised hair 54, and the raised pile 53 obtained by synthesizing the nonwoven fabric 56 is formed into a cylindrical shape. To do. Specifically, it is as follows.
(1) As shown in FIG. 11, a suspension of short fibers for non-woven fabric (a solution in which fibers are dispersed in water) is supplied onto a mesh fabric of a long raised pile unwound from a wide long reel 101. The suspension supplied from 102 is made up to form a fleece, the fleece is passed through a heating drum 103 and dried, and the adhesive sprayed from the emulsion adhesive spray device 104 is attached to the fleece, This is heated and dried by a hot air heater 105 to bond the intersections of the fibers to obtain a wound reel 106 of a raised pile with a wide and long nonwoven fabric in which short fibers for the nonwoven fabric are entangled around the raised hair of the long raised pile.
(2) As shown in FIG. 12, the raised pile unwound from the winding reel 106 of the raised pile with a wide and long non-woven fabric is slit into a plurality of strips by a round blade cutter 107, and the raised pile with a narrow and long non-woven fabric (original An anti-sheet winding reel 108 is obtained.
(3) As shown in FIG. 13, a raised pile wound from a winding reel 108 of a raised pile (raw sheet) with a narrow and long nonwoven fabric is wound around a mandrel 109, and the raised piles facing each other on the outer periphery of the mandrel 109 The both side edges are heat-sealed by the heater disk 110 to form the raised pile into a cylindrical shape. While the cylindrical raised pile with a narrow and long nonwoven fabric formed into a cylindrical shape is fed by the continuous pulling roller 111 and the tact feed roller 112, it is cut into a fixed length by the cutter 113 to obtain the tubular raised pile 53 with the nonwoven fabric.
