However, in the construction of the floor suction tool of the conventional electric vacuum cleaner as described above, the rotary brush rotates only the carpet, and when cleaning the tatami mat or the wooden floor surface. Used to remove dust with the suction force of the vacuum cleaner itself, but also to remove dust between the orchids on the tatami mat,
The effect of ejecting fine dust on the floor was insufficient. Further, even if powder or the like is accidentally spilled on the wooden floor, there is a problem that the suction force alone cannot sufficiently remove the powder. The present invention solves this problem, and aims to improve the dust collection performance and the brushing effect by ejecting fine dust on the floor surface or tatami mat.

[0004]

The first means of the present invention for achieving the above object is that the agitator is made of a flexible material in the longitudinal direction of the peripheral surface of the rotor, and has a large number of protrusions on the rotational direction side. The ridge strip formed by forming a main portion of a soft material and a groove on the opposite surface having the protrusion and made of a compression material such as synthetic fiber or natural fiber. In a configuration in which the member for use is arranged in the concave groove and integrated, when the main body of the suction tool is placed on the floor surface, the ridge strip is spaced from the floor surface, and the member for polishing is in contact with the member. .

A second means of the present invention is to shift the polishing member integrated with the protruding strip toward the rotation direction side with respect to the center of the groove formed in the rotor in the longitudinal direction of the circumferential surface. It is configured to be inserted and held.

[0006]

In the first means of the present invention described above, the protrusion strip of the agitator has a large number of protrusions formed on the rotational direction side, and the main body is made of a flexible material, and a groove is formed on the opposite surface of the protrusion. The scissors are made of compressed materials such as synthetic fibers and natural fibers, and the scrubbing members are sandwiched and integrated, and when the suction tool body is placed on the floor surface, the ridge strips are opened from the floor surface for polishing. Since the members are configured to come into contact with each other, when cleaning the wooden floor, the brushing member protruding from the tip of the ridge strip contacts. Since the brushing member is a soft cloth, it has a wide contact area with the surface to be cleaned, and the dust on the surface of the tatami mats that is familiar to the surface is removed. Compared with the formed cut pile spun cloth, it is possible to prevent entanglement of hair and thread waste.

In the second means, the brush member integrated with the protrusion strip is displaced in the direction of rotation with respect to the center of the groove formed in the rotor in the longitudinal direction of the circumferential surface. When cleaning, the ridges tend to bend due to the nature of the flexible material, and sparse for collapse is generated between the rotor and the ridges, so that it fits well on the surface and efficiently removes dust by squeezing. You can scrape. In addition, the load on the motor can be reduced when it comes into contact with the carpet, and the durability can be improved.
