[0004]
If the floor surface (flooring) is cleaned by rotating the rotary rotor of the conventional floor nozzle for a vacuum cleaner constructed in this way, the raised surface on one side of the base fabric rubs the floor surface, and the raised surface is on the floor surface. It is effective in wiping off dust and polishing the floor surface.
[0005]
[Problems to be solved by the invention]
According to the rotary rotor of the floor nozzle for a vacuum cleaner configured as described above, the end face of the base fabric is always in contact with the floor surface during rotation of the rotary rotor, and thus has a disadvantage that it is easily frayed by friction. . Moreover, since the waist of the base fabric itself was weak, a sufficient wiping effect or polishing effect could not be obtained. Furthermore, since the raised surface exists only on one side, the part that actually rubs the floor surface is called the back fabric if the forward path is the raised surface in the reciprocating travel of the floor nozzle, and the return path is the raised surface if the forward path is the base fabric. As described above, there is a drawback that the brushed surface cannot always be cleaned in both the reciprocating directions or the forward and reverse of the rotation of the rotary rotor.
[0006]
An object of the present invention is to provide a rotary rotor for a floor nozzle for a vacuum cleaner that has a high cleaning effect when the floor surface is flooring and is excellent in durability, and that can be efficiently cleaned even when it is a carpet or a tatami mat.
[0007]
[Means for Solving the Problems]
The rotary rotor of the floor nozzle for a vacuum cleaner according to the present invention employs the following means in order to achieve the above object. That is, the cleaning body is inserted and fixed in a plurality of spiral support grooves formed on the outer periphery of the rotor, and the cleaning body is inserted and fixed in the support groove in a rotary rotor of a vacuum cleaner floor nozzle that is rotated by an internal motor. A base material made of a flexible material such as a plastic material, and a cleaning sheet having one end fixed to the base material, and the cleaning sheet is a brushed cloth in which single fibers are densely planted on one side of a base cloth made of woven fabric or non-woven fabric The free end at the other end is folded back so that the raised surface becomes the outer surface to form a space portion, and a weight body is attached to the space portion.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1
1 to 6 show the first embodiment. In the figure, reference numeral 20 denotes a floor nozzle, which will be described below. Reference numeral 21 denotes a main body case formed of a lower case 23 having a horizontally long opening 22 on the bottom surface and an upper case 24 covering the lower case 23, with one end communicating with the opening 22 at the center and the other end being a main body case. 21 has a central passage 25 extending to the rear end.
[0010]
26 is an intake pipe whose one end is located in the central passage 25 and the other end is connected to a vacuum cleaner (not shown), 27 is a rotor 28 formed in a cylindrical shape from aluminum or plastic material, and the rotor 28 A reduction body 32 comprising a cleaning body 30 inserted and fixed in a plurality of spirally formed support grooves 29 on the outer periphery, a shaft bar 31 provided at both ends of the rotor 28, and a gear provided in the vicinity of the shaft bar 31. The shaft rod 31 is rotatably supported by bearings 33 fixed to both ends of the opening 22 in the longitudinal direction, and the free end 34 of the cleaning body 30 protrudes from the opening 22 during the rotation. .
[0011]
The cleaning body 30 includes a base 35 made of a flexible material such as a plastic material or a soft metal, which is inserted and fixed in a support groove 29 provided in a plurality of rotors 28, and one end fixed to the base 35 and the other end free. The end 34 is folded, and the end A is constituted by a cleaning sheet 36 made of woven fabric or non-woven fabric, which is fixed by welding, adhesive or sewing. Reference numeral 37 denotes an electric motor that rotates the rotary rotor 27, and a speed reduction body 32 </ b> A made of a speed reduction gear is fixed to the shaft 38. Reference numeral 39 denotes a transmission belt wound around the speed reduction body 32 and the speed reduction body 32A.
[0012]
In the floor nozzle 20 configured as described above, outside air passes through the central passage 25 through the opening 22 and is sucked into the cleaner body through the intake pipe 26 as the cleaner body (not shown) is operated.
At this time, the electric motor 37 also rotates, and the rotation is transmitted to the rotary rotor 27 by the speed reducer 32 and the belt 39. Of course, the cleaning body 30 of the rotary rotor 27 also rotates, its free end 34 protrudes from the opening 22 and the raised surface 41 collides with the floor surface to be cleaned while rotating, and dust attached to the floor surface, scattered dust, etc. Dust is placed on the external airflow that is directly lifted up or sucked into the opening 22. At this time, the free end 34 of the cleaning body 30 is folded back and formed double by welding, sewing, or adhesion, so that fraying and wear of the end portion A due to collision with the floor surface to be cleaned can be prevented.
[0013]
Further, since the free end 34 is doubled by folding, the weight is large and the centrifugal force accompanying the rotation is strong, so that the floor surface is struck, especially in the case of a carpet, it has the inside of the hair foot of the carpet. The effect of raising dust is increased, and the cleaning effect is improved. In addition, since only the free end 34 that directly contacts the floor surface is formed double, the cleaning sheet 36 is easier to bend during rotation, and the cleaning sheet 36 is lighter than the entire cleaning sheet 36 formed double. It also saves money. In addition, although the motor 37 demonstrated the drive device for rotating the rotation rotor 27, you may use the fan etc. by the attraction | suction force of an electric blower (not shown).
[0014]
Embodiment 2
FIG. 6 shows the second embodiment. 36A is a cleaning sheet made of a raised cloth 41 in which single fibers are densely planted on one side of a base cloth 40 made of woven or non-woven fabric, one end is fixed to the base 35, and the other end of the free end 34 is the raised face 41 and the outer surface. It is turned up so that the end A is fixed. For this reason, when the floor surface is cleaned with the floor nozzle 20, the floor nozzle 20 moves forward or backward on the floor surface, but the raised end 41 is always in contact with the free end 34 that contacts the floor surface. When the floor nozzle 20 is reciprocated, the cleaning and polishing effect is improved.
[0015]
Embodiment 3
A third embodiment is shown in FIGS. In FIG. 7, 42 is a space formed in the free end 34, and 43 is a weight body housed in the space 42. The weight body 43 is intended to increase the centrifugal force during rotation of the rotary rotor 27 and to improve the tapping effect on the cleaning floor surface. The weight body 43 has an appropriate specific gravity from rubber, plastic or metal regardless of the material. You only have to select one. Further, the weight body 43 may be an integral rod-shaped member as shown in FIG. 8, or may be divided into a plurality of pieces as shown in FIG. In any case, particularly on the floor surface formed with the carpet, the dust can be lifted and sucked by strongly hitting the dust accumulated in the hair feet, so that the cleaning effect is improved.
[0016]
Although all the rotary rotors 27 in the first to third embodiments described above are provided with the cleaning body 30, they are made of a flexible material such as rubber or plastic as shown in FIG. By using the soft blade body 44 to be used together with the cleaning sheets 36 and 36A, the floor surface cleaning effect is further improved.
[0017]
【The invention's effect】
A rotary rotor of a floor nozzle for a vacuum cleaner according to the present invention comprises a base made of a flexible material such as a plastic material for inserting and fixing a cleaning body into a support groove of the rotor, and a cleaning sheet having one end fixed to the base. The cleaning sheet is made of a raised cloth in which single fibers are densely planted on one side of a base fabric made of woven or non-woven fabric, and the free end at the other end is folded so that the raised surface becomes the outer surface to form a space portion. Since the weight is attached to the section, fraying due to friction between the edge of the cleaning sheet and the floor surface can be prevented, and the rotating surface of the rotating rotor can be cleaned on the raised surface in both the forward and reverse directions, and cleaning with flooring Increases efficiency. Also, not only the waist of the free end becomes strong, but also the centrifugal force when rotating the rotating rotor is large, the force to hit the floor surface is large, and in the case of carpets and tatami mats, dust is sufficiently raised, More efficient cleaning.
