Reference numeral 35 denotes a bearing for rotatably holding both ends of the rotary rotor 1 on the floor nozzle 30 for the cleaner.

  The groove 4 provided in the rotor 2 is formed in a spiral shape with a twist angle of 360 degrees over the entire width of the rotor 2. In this embodiment, the twist angle is set to 360 degrees, but the angle is not limited as long as the angle exceeds 540 degrees, 720 degrees, and 360 degrees.

  The cross-sectional shape of the groove portion 4 is a constant substantially ridge shape over the entire length of the rotor 2 and is formed so that the outer peripheral opening is narrower than the inside.

The cleaning body 3 is configured by combining two or more of the cleaning body A3a, the cleaning body B3b, the cleaning body C3c, and the cleaning body D3d.
Next, details of the cleaning body A3a, the cleaning body B3b, the cleaning body C3c, and the cleaning body D3d will be described with reference to FIG.

  The cleaning body A3a mainly has a function of sweeping up dust on the wooden floor and tiles. As shown in FIG. 3A, the entire cleaning body A3a is in the form of a strip and is bent with a core wire 3e in between. The brush piece 3f is composed of a belt-like body 3g, and the base portion of the brush piece 3f is covered with the core wire 3e and inserted into the groove 4 of the rotor 2. The core wire 3e is necessary for assembling the cleaning body A3a, and may be removed after the cleaning body A3a is completed.

  If the cleaning body A3a is assembled without using the core wire 3e, the core wire 3e is of course unnecessary. Moreover, you may use the brushed fabric brush processed by weaving the pile in the base fabric conventionally implemented.

  The cleaning body B3b mainly has a function of scraping dust on the carpet pile. As shown in FIG. 3 (b), the cleaning body B3b has a blade shape and a blade piece 3h formed of a soft material such as silicon rubber. And a base portion 3j that is integrally formed at the base portion and is inserted into the groove portion 4 of the rotor 2.

And a base portion 3n formed integrally with the root portion and inserted into the groove portion 4 of the rotor 2.

  The cleaning body D3d has a function of scraping dust mainly on the pile on the carpet. As shown in FIG. 3D, the cleaning body D3d is a brush made of a large number of fibers that are belt-shaped and bent with a core wire 3p in between. The strip 3r and the base portion of the brush strip 3r are covered with the core wire 3p, and the strip 3r is inserted into the groove 4 of the rotor 2. The brush piece 3r is set so that the fiber is stronger than the brush piece 3f of the cleaning body A3a.

  For example, the fiber diameter of the brush piece 3r of the cleaning body D3d is made larger than the fiber diameter of the brush piece 3f of the cleaning body A3a, or the material of the brush piece 3r of the cleaning body D3d is changed to that of the brush piece 3f of the cleaning body A3a. The fibers of the brush piece 3r may be made stronger than the brush piece 3f by using fibers that are more rigid than the material.

  The core wire 3p is necessary for assembling the cleaning body D3d, and may be removed after the cleaning body D3d is completed. Moreover, if the cleaning body D3d is assembled without using the core wire 3p, the core wire 3p is of course unnecessary.

  The cross-sectional shapes of the belt-like bodies 3g, 3s and the base portions 3j, 3n are substantially the same as the cross-sectional shape of the groove portion 4 of the rotor 2, and are not removed from the opening of the groove portion 4 after being inserted into the groove portion 4. The cross-sectional shapes of the strips 3g, 3s, the base portions 3j, 3n are not limited to the shapes in the present embodiment, and if the shape has a width larger than the opening width of the groove portion 4, Any shape is acceptable.

  The rotating rotor 1 is assembled by inserting the strips (3g or 3s) or the base (3j or 3n) of the cleaning body A3a, the cleaning body B3b, the cleaning body C3c, and the cleaning body D3d from one end of each groove portion 4. The rotor 2 is completed by press-fitting a holder 33 with a pulley on one end and a bearing holder 34 on the other end. The belt 32 is stretched over the completed rotary rotor 1 and is inserted into a predetermined portion of the vacuum cleaner floor nozzle 30 while both ends are held by the bearings 35, and the assembly to the vacuum cleaner floor nozzle 30 is completed.

  Next, a combination example of the cleaning body A3a, the cleaning body B3b, the cleaning body C3c, and the cleaning body D3d and the operation thereof will be described with reference to FIG.

  The example shown in FIG. 4A is a combination example particularly suitable for carpet cleaning, in which the cleaning body A3a and the cleaning body B3b having a smaller projection margin than the cleaning body A3a are alternately mounted in the groove portion 4, When the rotary rotor 2 is rotated counterclockwise, the cleaning body A3a having a large protrusion allows the carpet pile to be pushed down, and then the cleaning body B3b having the smallest protrusion allows the pile to be spread and scrapes dust adhering to the pile. The cleaning body A3a that is taken up and scrapes up the dust in the back of the pile can effectively clean the carpet. Further, even if a long hair wraps around the cleaning body A3a during carpet cleaning, it does not wrap inward from the tip of the cleaning body B3b, so that the hair can be easily removed by cutting with scissors or the like.

  The example shown in FIG. 4B is a combination example particularly suitable for carpet cleaning and wood floor cleaning. In the counterclockwise direction, the cleaning body A3a having the largest protruding margin and the cleaning body B3b having the smallest protruding margin are provided. And a cleaning body A3a and a cleaning body C3c having a protrusion margin shorter than the cleaning body A3a and longer than the cleaning body B3b are sequentially mounted in the groove portion 4, and when the rotary rotor 2 is rotated counterclockwise on the wooden floor, The tip of the brush piece 3f of the cleaning body A3a having a large protrusion enters the groove of the wooden floor and scrapes out the dust inside. Next, the cleaning body C3c polishes the surface of the wooden floor, and the next cleaning body A3a scrapes off the dust. increase. During this time, the cleaning body B3b having a short allowance only idles and does not contact the surface of the wooden floor.

  Moreover, when it operates on a carpet with the same combination, the dust adhering to the pile of the carpet is effectively scraped off by the cleaning body A3a and the cleaning body B3b. Moreover, the same effect is acquired also in cleaning on a tatami mat.

  The example shown in FIG. 4 (c) is a combination example mainly suitable for cleaning a wooden floor. In the clockwise direction, the cleaning body A3a, the cleaning body C3c having a protruding margin larger than the cleaning body A3a, and the cleaning body A3a The cleaning body B3b, which has a shorter protrusion than the cleaning body A3a, is mounted in order. When the rotary rotor 2 is rotated counterclockwise on the wooden floor, the cleaning body C3c having a polishing function or a wiping function is always Since the surface is traced, the polishing effect is extremely large. Moreover, the same effect is acquired also in cleaning on a tatami mat.

  The example shown in FIG. 4 (d) is another combination example particularly suitable for carpet cleaning, in which the cleaning body A3a and the cleaning body D3d having a smaller projection margin than the cleaning body A3a are alternately mounted in the groove portions 4. When the rotary rotor 1 is rotated counterclockwise, the cleaning body A3a having a large protrusion allows the carpet pile to fall down, and then the cleaning body D3d having a small protrusion and the brush piece 3r is stronger than the cleaning body A3a is applied to the pile. At the same time as spreading, the dust adhering to the pile is scraped off at the tip of the brush piece 3r. The next cleaning body A3a scrapes up the dust in the back of the pile, and the carpet can be effectively cleaned.

  Further, since all of the cleaning body A3a and the cleaning body D3d are brush pieces 3f and 3r made of a large number of fibers, even if high-speed rotation is performed, a buzzing sound generated when the air is hit like the blade piece 3h of the cleaning body B3b There is no siren sound and noise can be reduced.

  As described above, according to the present embodiment, the rotary rotor 1 suitable for the type of the surface to be cleaned is attached to the plurality of grooves 4 by combining different cleaning bodies 3 in various combinations while using the same rotor 2. It can be freely manufactured.

  Furthermore, if the rotary rotor 1 of the floor nozzle for a vacuum cleaner in this embodiment is used, one cleaning body 3 mounted in one groove is twisted 360 degrees, so that the tip of the cleaning body 3 is maximized. The two places can be brought into contact with the floor.

  Moreover, since the rotary rotor of the floor nozzle for a vacuum cleaner in this embodiment has four cleaning bodies 3 attached, the cleaning body 3 can be brought into contact with the floor surface at a maximum of five locations. The total area in contact with is increased, and the dust sweeping effect is improved. Further, since the pressure applied to the rotor 2 from the floor surface can be uniformly distributed over the entire length of the rotor 2 by bringing a large number of cleaning bodies 3 into contact with the floor surface, the core blurring of the rotor 2 during rotation is minimized. be able to.

  Further, the cleaning body 3 in contact with the floor surface has a larger inclination angle with respect to the longitudinal direction of the rotor 2 than that formed in a spiral shape with a twist angle of 180 degrees. The contact state of the tip of the floor with the floor surface can be made to approach point contact from side contact, thereby reducing the contact area between the floor surface and the cleaning body 3 and sliding between the cleaning body 3 and the floor surface. Resistance can be reduced. As a result, the load applied to the motor 31 that is a drive source for driving the rotary rotor 1 is reduced, and the motor 31 can be downsized accordingly.

In addition, the same code | symbol is attached | subjected about the same part as the rotary rotor of the floor nozzle for vacuum cleaners in the said 1st Embodiment, and the description is abbreviate | omitted.

  When the twist angle of the spiral groove 4 provided in the rotor 2 is increased, the difference between the developed dimension at the tip of the cleaning body 3 attached to the groove 4, for example, the cleaning body B 3 b, and the developed dimension of the groove 4. Therefore, when using a belt-like cleaning body B3b having the same length on both sides as shown in FIG. 3B, the tip of the cleaning body B3b falls down even though it is formed of a soft material. There arises a problem that the dust scooping performance is deteriorated.

  Therefore, in the present invention, as shown in FIG. 5, the cleaning body B3b is formed in an annular shape when placed on a flat surface, and the outer circumferential length Lout and the inner circumferential length Lin are respectively set to the cleaning body B3b as the rotor. The developed dimension of the tip of the cleaning body B3b when attached to the second groove part 4 is equal to the developed dimension of the groove part 4, so that the cleaning body B3b can be easily mounted in the groove part 4.

  Moreover, when attached to the groove 4 of the rotor 2, the tip of the cleaning body B3b does not fall down, and the dust scavenging performance is improved. Furthermore, since it has a ring-like shape on a plane, the structure of the molding die is simplified, and the number of molding steps is reduced as well as the cost of the die, so that it can be formed at a low cost.

  Moreover, when changing the length of the rotor 2 having the same cross-sectional shape and developing the parts of the rotary rotor 1, it is possible to cope by simply cutting the cleaning body B3b formed in an annular shape according to the length of the rotor 2. There is no need to prepare a plurality of molds for the cleaning body B3b, and inventory management is facilitated.
