【Example】
(Example 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0024]
In FIG. 1, the vacuum cleaner 1 has a suction body 13 for sucking dust and a suction tool 3 detachable from the suction body 13, and an extension pipe 2 having the suction tool 3 detachably mounted at a tip thereof includes: The hose 6 connected to the handle 4 and connected to the handle 4 is connected to a cleaner body 7 by a hose joint 5. In addition, the suction body 13 and the suction tool 3 can be covered even when the suction tool 3 is attached to the suction body 13 or the suction tool 3 alone with the suction tool 3 removed from the suction body 13. The dust on the cleaning surface can be sucked, and the dust can be transferred to a dust collecting portion (not shown) of the cleaner body 7.
[0025]
As shown in FIG. 2, the suction tool 3 includes a rotor 8a wound with a cut fiber-like raised cloth made of a fine fiber spun cloth, and a gap between the rotor 8a and the suction chamber wall 14b is formed in the suction chamber wall. It is narrower than the gap with 14a, and is provided facing the suction chamber 11 having an opening for dust suction. As shown in FIG. 3, the fibers of the brushed cloth wound around the outer periphery of the rotor 8a are laid down in one direction substantially perpendicular to the rotating shaft 8c (the direction opposite to the rotating direction), and are spirally wound. It is wound in a shape. When the rotor 8a is rotating, it is arranged at a position where the fibers of the brushed cloth and the surface to be cleaned are pressed against each other by 0.5 mm.
[0026]
In the present embodiment, one rotor is provided. However, even if two or more rotors are provided, the wiping and sweeping effects described below can be sufficiently exerted.
[0027]
The operation in the above configuration is as follows.
[0028]
When the cleaner main body 7 is operated, an electric blower (not shown) built in the cleaner main body 7 is operated, whereby suction air a is sucked through the space between the rotor 8a and the suction chamber wall 14a. The suction air “a” flows toward the chamber 11. Thereafter, the suction air a collides with the raised cloth of the rotor 8a, thereby rotating the rotor 8a by wind pressure. In this embodiment, the rotor 8a is rotated by the suction air a flowing into the suction chamber 11 through a gap between the surface to be cleaned and the lower surface of the suction tool 3. An opening (not shown) is provided on a side surface of the suction chamber, and suction air a flows into the suction chamber 11 from the opening, and the rotor 8a is rotated by the suction air flowing into the suction chamber 11. Is also good.
[0029]
The fibers of the raised cloth wound around the outer periphery of the rotor 8a are laid down in a direction substantially perpendicular to the rotation axis 8c (in a direction opposite to the rotation direction), and the suction air a is generated by the laid down air. Since the front side of the blanket collides with the rotor 8a, the lying fibers become wind receivers, and a strong rotational force is obtained. The suction air a collides with the rotor 8a from the tip side of the fallen raised cloth, but if the suction air a does not flow from the root side of the fibers of the raised cloth, a rotational force can be obtained. It is preferable that the suction air a flows into the left and right directions in the range of approximately 45 ° with respect to the tip of the raised cloth.
[0030]
As described above, in the present embodiment, a large amount of air flows into the rotor 8a by increasing the gap between the rotor 8a and the suction chamber wall 14a, and the gap between the rotor 8a and the other outer wall 14b decreases. To provide a suction device that is small in size, light in weight, inexpensive, and has high wiping, sweeping, and polishing performance. Can be.
[0031]
Further, since the surface of the rotor 8a is made of a brushed cloth, it is possible to provide a suction tool having high wiping, sweeping, and polishing performance on the surface to be cleaned.
[0032]
Further, by arranging the longitudinal direction of the rotor 8a in a direction substantially perpendicular to the cleaning direction, it is possible to make the suction tool horizontally long in the cleaning direction, and to provide a suction tool capable of cleaning a wide range at a time. be able to.
[0033]
In addition, since the air is directly applied to the fibers of the raising cloth to rotate it, no other mechanical parts are used and only the raising cloth is used, so that it is possible to provide a suction device with a simple structure, high reliability and low cost. it can.
[0034]
In addition, by making the fibers of the raised cloth fall down in a direction substantially perpendicular to the rotation axis 8c (in a direction opposite to the rotation direction), it is possible to receive wind pressure. It is possible to provide a suction tool having high wiping, sweeping and polishing performance.
[0035]
Next, the fibers of the raising cloth are laid down in one direction (substantially perpendicular to the rotation axis (the direction opposite to the rotation direction)), so that the fibers are generated only when the air hits, and the wind is generated like a windmill. This makes it possible to provide a suction tool that is easily affected by the squeezing force, has a higher rotational force, and has high wiping, sweeping and polishing performance.
[0036]
Also, by winding the raised cloth spirally around the outer periphery of the rotor 8a, the airflow collides against the joints of the raised cloth, which makes it easier to receive the wind, so that a larger rotational force can be obtained, and wiping, sweeping, A suction tool having high polishing performance can be provided.
[0037]
Furthermore, when the rotor 8a is rotating, if the contact allowance (pressure contact allowance) between the fibers of the brushed cloth and the surface to be cleaned is less than 0.2 mm, the contact area with the surface to be cleaned is too small, so that wiping is performed. Low sweeping and polishing performance. When the contact is made 1 mm or more, the number of revolutions is rapidly reduced, and the wiping, sweeping and polishing performance is low. Therefore, by making contact (pressure contact) in the range of 0.2 mm to 1 mm, the surface to be cleaned can be sufficiently cleaned with the brush cloth while minimizing the decrease in the number of rotations.
[0038]
Further, when the suction tool 3 is mounted on the suction body 13, the surface to be cleaned can be cleaned widely, and when the suction tool 3 is detached from the suction body 13 and used alone, the suction body 13 cannot be used. It can clean very narrow places.

It is sucked into the cleaner body 7 through the extension pipe 2, the handle at hand 4, the hose 6, and the hose joint 5.
[0043]
Further, the air volume control valve 9 is opened by being pressed by the suction air flowing into the suction chamber 11, and stops at a position where the pressing is balanced with the urging force of the spring 10. Accordingly, when the air volume is large, the interior of the suction chamber 11 is made closer to open, and by reducing the rotation speed of the rotors 8a and 8b, noise is prevented. , 8b, the wiping, sweeping and polishing performance can be improved.
[0044]
As described above, in the present embodiment, since a large amount of air flows between the rotors 8a and 8b by increasing the gap between the two rotors 8a and 8b, the two rotors 8a and 8b It rotates so as to be drawn into the gap between the two rotors, and can clean the surface to be cleaned without sweeping the dust out of the suction chamber.

[0048]
The operation in the above configuration is as follows.
[0049]
When the cleaner main body 7 is operated, an electric blower (not shown) built in the cleaner main body 7 is operated, and the suction air “a” flows toward the suction chamber 11. Thereafter, the suction air a collides with the raised cloth of the rotors 8a and 8b, thereby rotating the rotors 8a and 8b by wind pressure, and wiping, sweeping and polishing dust on the surface to be cleaned. And dust is sucked into the cleaner body 7 through the extension pipe 2, the hand handle 4, the hose 6, and the hose joint 5.
