In the brush bristle material of such a general rotary brush, there is a problem that the cleaning effect is biased to one of the floor and the carpet and the cleaning efficiency is lowered in the specification of one rotary brush for the surface cleaning of the wood floor and the sweeping cleaning of the carpet.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a rotary brush for an electric vacuum cleaner, which exhibits high cleaning performance with respect to surfaces to be cleaned of different materials, and an electric vacuum cleaner provided with the rotary brush.
Means for solving the problems
Further, according to the present invention, there is provided a rotary brush of an electric vacuum cleaner rotatably mounted on a suction port body of the electric vacuum cleaner,
the rotary brush has a cylindrical body having a plurality of groove portions on a surface thereof, and a plurality of brush members attached to the respective groove portions,
the brush member has a strip-shaped base portion fitted into the groove portion of the tubular body, and hard and soft bristle portions implanted in two rows in a longitudinal direction on one surface of the base portion and protruding outward from the groove portion,
in at least two of the brush members, the arrangement order of the hard bristle portions and the soft bristle portions in the circumferential direction around the axis of the rotating shaft of one of the brush members is opposite to the arrangement order of the hard bristle portions and the soft bristle portions in the circumferential direction of the other brush member.
Further, according to the present invention, there is provided an electric vacuum cleaner including a suction port body to which the rotating brush is rotatably attached and a cleaner main body connected to the suction port body.
Advantageous effects
The rotating brush of the electric dust collector is configured in such a manner that, in at least two brush members, the arrangement order of the hard and soft bristle portions in the circumferential direction of one brush member is opposite to the arrangement order of the hard and soft bristle portions in the circumferential direction of the other brush member.
That is, when at least two brush members having the same configuration are arranged adjacent to each other, the brush structure can be configured such that the hard bristle portions sandwich the soft bristle portions of the respective brush members on both sides in the rotation direction.
According to this configuration, since the hard bristle portion can be disposed at the end portion on the side of the soft bristle portion in the rotation direction, dust in the carpet fibers can be efficiently swept out and cleaned by the bristle field.
In addition, since the soft fur portions are sandwiched between the hard fur portions on both sides in the rotation direction, the soft fur region having a high density can be formed in a wide area, and therefore, the cleaning efficiency of the wood floor surface can be improved.
Thus, the rotary brush according to the present invention can effectively clean a surface to be cleaned, which is different from a carpet, a wood floor, or the like.
Further, since the space other than the brush member in the rotary brush can be configured at a wide pitch, it is possible to efficiently convey large dust (e.g., dust cake, candy pieces, etc.) to the suction port direction from the wide space.

(4) The cylindrical body has a plurality of pairs of adjacent grooves,
the plurality of brush members may be attached to the plurality of pairs of grooves to form a plurality of pairs of brush members, and the hard bristle portions and the soft bristle portions may be arranged in the circumferential direction of one of the brush members in each of the pairs of brush members in an order opposite to the order in which the hard bristle portions and the soft bristle portions are arranged in the circumferential direction of the other of the brush members.
According to this configuration, since the brush member can be provided with a plurality of pairs of brushes in which the hard bristles sandwich the soft bristles of the pair of brush members in the rotation direction, the cleaning efficiency of both the surfaces of the carpet and the wood floor can be further improved.
(5) The brush member may further include a single brush portion having a soft bristle portion attached to the groove portion of the pair of brush members.
According to this configuration, since the area of the soft fur portion sandwiched by the hard fur portions on both sides in the rotation direction can be further enlarged, the surface cleaning of the wood floor can be enhanced while maintaining the effective cleaning ability for the carpet.
(6) The two brush members made of the same material are inserted into the two adjacent groove portions in diametrically opposite directions.
According to this configuration, two brush members arranged adjacent to each other can be made common, and the number of types of members can be reduced.
Furthermore, the disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is indicated not by the above description but by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the claims.
