[Problems to be solved by the invention]
However, in the rotary cleaning body described above, the brush base is formed by spirally twisting aluminum material or the like in advance, and therefore, the elongated rectangular brush member or scraping member of the spirally twisted engagement recess is formed. It is not easy to attach by sliding the base end side, and there is a problem that productivity is not good.
[0005]
In this regard, for example, a brush base is formed in a linear shape with a flexible member, and after the base end portion of the brush member or the scraping member is locked in the linear engagement recess, the brush base is moved to the brush member. Alternatively, it is conceivable to use a configuration in which a spiral member is twisted in the circumferential direction together with the scraping member.
[0006]
However, in this configuration, there is a risk that a twisting load, that is, stress, is applied to the brush base due to a restoring force that tries to return to the brush base after being twisted in a spiral shape.
[0007]
The present invention has been made in view of the above points, and provides a rotary cleaning body capable of improving manufacturability and reducing a torsional load, a suction port body of a vacuum cleaner provided with the same, and a method of manufacturing the rotary cleaning body. The purpose is to do.
[0008]
[Means for Solving the Problems]
The present invention is flexible, and a mounting member having an outer peripheral surface along a mounting recess formed in advance spirally toward the circumferential direction in the axial direction, and the cleaning member softer than the mounting member The cleaning member protrudes in the radial direction of the mounting member in a state where the mounting member is twisted by applying an external force so that the mounting recess is linear along the axial direction of the mounting member. It is attached to the outer peripheral surface of the mounting member by locking the base end side to the mounting recess, and by releasing the external force twisting the mounting member and returning the mounting member to its original state, the mounting member is directed in the circumferential direction. Thus, it is formed in a spirally twisted state . The flexibility to form a mounting member in a pre-twisted state with the base end side of the cleaning member mounting recess while returning to a straight line along the axial direction of the mounting member locking to the mounting recess As a result, the productivity is improved and the cleaning member softer than the mounting member releases the external force twisting the mounting member and returns the mounting member to its original state, thereby spiraling in the circumferential direction with respect to the mounting member. Therefore, since the restoring force in the circumferential direction is not applied to the mounting member in the assembled state, the torsional load is reduced.

On the inner peripheral surface of the belt body 64, a gear groove (not shown) having an interval and a size capable of engaging with each of the gear groove of the gear 63 and the gear groove 46 of the gear portion 47 is formed. Therefore, when the motor 61 is driven, the gear 63 is rotated by the rotation of the rotating shaft 62 of the motor 61, and the belt body 64 is rotated by the rotation of the gear 63, so that one receiving plate 41 of the rotating brush 13 is rotated. The rotating brush 13 is driven to rotate in the circumferential direction.
[0031]
Next, a method for assembling the floor brush according to the embodiment will be described.
[0032]
First, as shown in FIG. 2, a flexible brush base 14 is twisted and extruded so that the engagement recesses 15 are formed in a spiral shape on the outer peripheral surface in the circumferential direction.
[0033]
Next, an external force is applied to one end of the brush base 14 in the axial direction, and one end of the brush base 14 in the axial direction is twisted, for example, about 180 ° in the circumferential direction with respect to the other end, as shown in FIG. Each engaging recess 15 is linear along the axial direction of the brush base 14.
[0034]
In this state, the brush mounting portion 23 of the brush member 21 and the blade mounting portion 28 of the scraping member 22 are moved so that the brush member 21 and the scraping member 22 protrude in the radial direction of the brush base 14. These are slid into the respective engagement recesses 15 from one end in the axial direction to the other end to be locked. At this time, the brush member 21 and the scraping member 22 are attached so as to alternate along the circumferential direction of the brush base 14.
[0035]
Thereafter, when the external force that twists the brush base 14 is released, the restoring force of the member that forms the brush base 14 causes the brush base 14 to move in the circumferential direction together with the brush member 21 and the scraping member 22 as shown in FIG. It returns to the original state twisted in a spiral.
[0036]
Then, as shown in FIG. 1, the shaft 32 is inserted into the shaft insertion hole 31 of the brush base 14 having the brush member 21 and the scraping member 22 attached to the outer peripheral surface, and as shown in FIG. As shown in FIG. 5, the ribs 43 of the receiving plate 41 are fitted into the engaging recesses 15 from both ends of the brush base 14, respectively.
[0037]
In this state, the pin insertion holes 53 of each receiving plate 41 are aligned and communicated with the pin insertion holes 33 and 33 of the shaft 32, and the pins 54 and 54 are inserted to connect the receiving plates 41 to the shaft 32, respectively. Let
[0038]
Thereafter, bearings 48 are rotatably fitted and attached to both end portions of the shaft 32 protruding outward from the insertion holes 42 of the receiving plates 41 to form the rotary brush 13.
[0039]
Then, each of the bearings 48 of the rotary brush 13 is fitted into the shaft support recess 51 of the case body 11, and the rotary brush 13 is rotatably supported in the suction port 12 of the case body 11. The floor brush 9 is completed.
[0040]
Next, the operation of the above embodiment will be described.
[0041]
First, when cleaning, the floor brush 9 is connected to the cleaner body 1 through the hose body 4 and the extension pipe 8. Then, the gripper 7 of the hose body 4 is held and pushed to run the floor brush 9 back and forth on the floor surface.
[0042]
At this time, dust on the floor surface is sucked together with air from the suction port 12 of the floor brush 9 by the suction force generated by driving the electric blower 2 in the cleaner body 1.
[0043]
Further, when the predetermined setting button 6 of the hand operation part 5 of the hose body 4 is turned on and the rotary brush 13 of the floor brush 9 is driven to rotate, the rotation of the brush member 21 of the rotary brush 13 The floor surface is brushed by the brush bristles 24 of the brush member 21. That is, when the floor surface is between boards, dust stuck to the floor surface is swept away from the floor surface, polished, and sucked into the suction port 12 of the floor brush 9.
[0044]
At the same time, the dust on the floor surface is swept away by the rotation of the scraping member 22 of the rotary brush 13. That is, when the floor surface is a carpet or the like, the dust that has entered the carpet is removed by the scraping portion 26 of the blade 27 of the scraping member 22 to the outside. It is sucked into the inlet 12.
[0045]
Thereafter, the air sucked together with dust from the suction port 12 of the floor brush 9 was sucked from the floor brush 9 into the main body suction port 3 of the cleaner body 1 through the extension pipe 8 and the hose body 4 in order. Thereafter, the dust sucked into the dust collecting pack accommodated in the cleaner body 1 and sucked together with the air is captured.
[0046]
As described above, in the above-described embodiment, on the outer peripheral surface of the brush base 14 having flexibility, the engagement concave portions 15 that are spirally formed in advance in the circumferential direction are provided along the axial direction. The proximal end sides of the brush member 21 and the scraping member 22 that are softer than the brush base 14 are locked to the respective engagement recesses 15, and the brush member 21 and the scraping member 22 are attached to protrude from the outer peripheral surface of the brush base 14. The configuration.
[0047]
As a result, when the rotating brush 13 is assembled, the brush member 21 and the brush member 21 are twisted in the circumferential direction so that each engaging recess 15 is linear along the axial direction of the brush base 14. The brush member 21 and the scraping member 22 are easily engaged with the brush base 14 by sliding the base end side of the scraping member 22 from one end side in the axial direction of each engagement recess 15 toward the other end side. Since it can stop, productivity can be improved.
[0048]
Further, since the brush base 14 is preliminarily molded in the circumferential direction, the brushes are formed on the respective engagement recesses 15 of the brush base 14 that are linear along the axial direction of the brush base 14. When the base ends of the member 21 and the scraping member 22 are locked, the brush base 14 itself is spirally twisted in the circumferential direction by the restoring force of the brush base 14 itself.
[0049]
For this reason, in the state where the rotating brush 13 is assembled, the restoring force in the circumferential direction is not applied to the brush base 14, and the torsional load in the circumferential direction of the brush base 14 when the rotating brush 13 is assembled, that is, stress Can be reduced.
[0050]
Furthermore, since it is difficult for stress in the circumferential direction to be applied to the brush base 14 in a state where the rotating brush 13 is assembled, stress in the circumferential direction is applied to the rib 43 of the receiving plate 41 that fits into the locking recess 29 of the brush base 14. It is difficult to add, and damage such as bending of the rib 43 can be prevented more reliably.
[0051]
Then, by making the restoring force of the brush base 14 greater than the restoring force of the brush member 21 and the scraping member 22, after attaching the proximal end side of the brush member 21 and the scraping member 22 to the brush base 14, the brush Since the brush base 14 is reliably restored in a spiral shape together with the brush member 21 and the scraping member 22 without separately applying an external force for twisting the base 14 in the circumferential direction, an external force is separately applied to twist the brush base 14. Compared with the conventional case of adding, it can manufacture more easily and can improve manufacturability more.
[0052]
In the above embodiment, a plurality of rotating brushes 13 may be disposed on the floor brush 9. In addition, although the rotary brush 13 is driven to rotate by the motor 61, a configuration in which the rotary brush 13 is driven to rotate by intake air from the electric blower 2 can also be adopted.
[0053]
In addition, although four engagement recesses 15 are provided in the brush table 14, at least one or more may be provided in accordance with the number of cleaning members attached to the brush table 14. In addition, the cleaning member is not limited to the brush member 21 and the scraping member 22, and may be a floor polishing member having a cloth blade, for example. Further, the brush members 21 and the scraping members 22 are alternately attached to the engaging recesses 15 of the brush base 14, but are not limited to each other, and one type of scraping member 22 is provided in each of the engaging recesses 15 of the brush base 14. May be attached, or multiple types may be attached.
[0054]
Further, when the rotating brush 13 is assembled, the brush member 21 or the scraping member 22 becomes a load that prevents the brush base 14 from being restored to the original twisted state, and the engagement recess 15 of the brush base 14 is made linear. If the brush base 14 does not completely return to its original twisted state simply by releasing the external force, an auxiliary external force may be applied to the brush base 14 to restore the brush base 14 to the original twisted state. Is possible.
[0055]
Further, the present invention is not limited to the canister type electric vacuum cleaner, but is an upright type in which the floor brush 9 is directly formed on the lower surface of the vacuum cleaner body 1, and the self-propelled type in which the vacuum cleaner body 1 and the floor brush 9 are integrated. Even a vacuum cleaner or a handy type can be used correspondingly.
[0056]
【The invention's effect】
According to the present invention, the flexible attachment member is formed in a twisted state, and the attachment recess is returned to the linear shape along the axial direction of the attachment member. in that locking, it is possible to improve the manufacturability, the circumferential direction relative to the mounting member than the mounting member cleaning member of the soft is opened the external force twisting the mounting member by returning the mounting member to the original state Therefore, since the restoring force in the circumferential direction is not applied to the mounting member in the assembled state, the torsional load can be reduced.
