The core wire 27a is necessary for assembling the cleaning body 27, and may be removed after the cleaning body 27 is completed. Moreover, if the cleaning body 27 is assembled without using the core wire 27a, of course, the core wire 27a is unnecessary.

Next, the detail of the cleaning body A28 is demonstrated using FIG.
FIG. 5A shows a state before the cleaning body A28 is mounted in the groove 25 of the rotor 26. The entire cleaning body A28 is formed substantially flat, and the base pillar portion A28b and the base pillar are formed at both ends. A portion B28c is arranged, and a plurality of scooping whip portions 28a that connect the base pillar portion A28b and the base pillar portion B28c are integrally and obliquely formed.

  The base pillar portion A28b has a widening convex portion 28d as an engaging portion, and, on the other side, a concave portion 28e serving as an engaged portion with which the convex portion 28d engages at a position facing the convex portion 28d. Are provided in plural.

  In the present embodiment, the concave portion 28e corresponding to one convex portion 28d is shown and described at one location, but the concave portion 28e corresponding to one convex portion 28d can be selected. A plurality of places may be provided.

  Further, as shown in FIG. 5 (d), the cross-sectional shape of each scraping whip 28a is such that the tip 36 is tapered from the center of the cross-section with respect to the rotation direction of the rotary rotor, and the tips of both ends are tapered. A scooping portion 37 is formed on a line on the inner side of the rotary rotor that connects the portions 36.

  The operation and action of the vacuum cleaner floor nozzle 20 in the present embodiment having the above-described configuration are as follows.

  When the electric vacuum cleaner main body 10 is operated, the handle pipe 14a is operated, and the vacuum cleaner floor nozzle 20 is operated on a wooden floor or a carpet, the rotary rotor 22 incorporated in the vacuum cleaner floor nozzle 20 rotates, The dust on the cleaning surface is swept up or scraped up by the cleaning body 27 and the cleaning body A28, and the dust together with the air passes through the extension pipe 15 and the hose 14 from the opening of the lower case 21 by the suction force of the electric blower 12. The dust flows into the dust collecting chamber 11 where dust is collected.

  Here, in particular, the operation of the scooping whip part 28a during carpet cleaning will be described. When the rotary rotor 22 rotates, as shown in FIG. 5E, the scraping whip 28a enters the carpet pile 34. At this time, the tip 36 on the rotational direction side of the rotary rotor 22 is piled up. Since the dust 35 is picked up on the scooping portion 37 while abutting the pile 34, the dust 35 attached to the carpet pile 34 is scooped up with the same action as scooping up the golf ball on the rough with the iron. Compared with the conventional method of scraping dust with a peripheral blade, dust 35 is efficiently and reliably removed from the pile 34 and sucked into the main body 10 of the vacuum cleaner, so that the cleaning performance is dramatically improved. To improve.

  Further, since the scooping whip portions 28a overlap each other, for example, as shown in FIG. 6 (a), the cleaning body A of the rotary rotor 22 is used as a surface to be cleaned. When the next scooping whip part 28a on the back side of the scooping whip part 28a overlaps with the surface to be cleaned, the scooping whip part 28a on the rotational direction side is positioned behind Since it is backed up by the next scooping whip part 28a, it is not necessary to increase the flexural strength of each scooping whip part 28a. Therefore, the dust scooping performance can be improved.

  Further, as shown in FIG. 6B, when the method of overlapping the scraping lashes 28a constituting the cleaning body A of the rotary rotor 22 is overlapped so as to be opposite to that in FIG. The tip of the scooping whip 28a that is bent in contact with the cleaning surface moves away from the surface to be cleaned and hits the next scooping whip 28a when trying to return to the original state. In addition, the flapping operation by the scooping whip 28a propagates to the object to be cleaned such as the carpet pile 34 and the dust is knocked out, so that the dust removing performance is greatly improved.

  As described above, according to the present embodiment, the dust attached to the carpet pile or the like is scraped off so as to be scooped up by the scooping whip 28a. In comparison, the dust removal performance from the surface to be cleaned is dramatically improved.

  In addition, since each of the scooping whip portions 28a overlaps each other, depending on how they are stacked, the flexibility of the scooping whip portion 28a is improved, and the dust scooping performance is further improved. The dust removal performance can be greatly improved by the striking effect of the whip part 28a.

  Further, the cross-sectional shape of the scooping whip portion 28a has a shape in which the tip end portion 36 is tapered with respect to the rotational direction of the rotary rotor 22, so that the dust scooping action is more effectively performed. As a result, dust removal performance is improved.

  Further, after forming the cleaning body A28 in an unfolded state, both ends of the cleaning body A28 are overlapped in the longitudinal direction to form a plurality of scooping whip portions 28a in a loop shape and incorporated into the rotor 26. Since the mold structure is simplified and the molding cycle is shortened, it can be formed at a low cost.

  Further, the convex portion 28d and the concave portion 28e provided on the cleaning body A28 serve as an alignment means for aligning the base column portion A28b and the base column portion B28c, thereby aligning the base column portion A28b and the base column portion B28c. Since it can be performed accurately and reliably, the shape of the scooping whip 28a is stable, and high dust scooping performance is also maintained.

  Further, by engaging the convex portion 28d formed in a widened shape with the concave portion 28e, the base pillar portion A28b and the base pillar portion B28c of the cleaning body A28 are temporarily fixed, and the cleaning body A28 is connected to the groove portion 25 of the rotor 26. It is very easy to mount, and furthermore, the position of the base column part A28b and the base column part B28c is not shifted due to vibration generated when the rotary rotor 22 is rotated during operation. The shape of the portion 28a is always stable, and high dust scooping performance is maintained.

  In addition, since the length of the whip-up whip 28a is constant, the distance between the roots when they are overlapped is changed, that is, a plurality of concave portions 28e corresponding to one convex portion 28d are provided and selected. Therefore, it is possible to change the height of the loop-like scooping whip part, and by changing the height of one rotary rotor 22, various types of cleaning can be performed. It can correspond to a surface. In addition, a single component can be expanded to multiple models, the components can be shared, and costs can be reduced.

  Further, by connecting the vacuum cleaner floor nozzle 20 described in the above embodiment to the main body 10 of the vacuum cleaner through the hose 14 and the extension pipe 15, it is possible to provide a vacuum cleaner having excellent dust collection performance. .

In the above-described embodiment, the rotary rotor 22 is driven to rotate by the motor 24. However, the rotary rotor 22 receives a suction air (not shown. The brush rotor is formed in the present embodiment). The cleaning body 27 may be provided), and when the electric vacuum cleaner main body 10 is operated, the rotating rotor 22 may be rotated by applying suction air flowing from the opening provided on the bottom surface of the vacuum cleaner floor nozzle 20 to the blade. In this case, since the motor 24 is not necessary, the floor nozzle 20 for the vacuum cleaner is lightened, thereby improving the operability of the floor nozzle 20 for the vacuum cleaner.
Further, in the above embodiment, a plurality of scooping whip portions 28a are provided, but only one may be provided.

  As described above, the floor nozzle for a vacuum cleaner according to the present invention can be reliably used without pressing dust against a surface to be cleaned such as a pile of a carpet by the loop-shaped scraping whip part of the cleaning body A attached to the rotary rotor. It is extremely excellent in scooping up and removing dust, and is applicable not only to a vacuum cleaner but also to various devices that collect or collect dust and other objects using a rotating member.
