る電気掃除機の床用吸込具である。Means for Solving the Problem and Its Action The floor suction device for an electric vacuum cleaner of the present invention has the following two forms. A first form thereof is a suction tool body having an opening on a bottom surface, a rotary brush which is housed in the suction tool body facing the opening, and a drive source which is built in the suction tool body and drives the rotary brush. The rotating brush comprises: a rotating body having a plurality of grooves formed in the longitudinal direction; brush members respectively disposed in the grooves; and blades made of an elastic material. A floor suction tool for an electric vacuum cleaner, wherein a bulging portion bulging toward the outer peripheral direction of the brush member is formed at the opening edge of the groove.

れらの表面を磨く。The turning radius of the blade is smaller than the turning radius of the brush member. Therefore, when cleaning the carpet, part of the suction tool body or the moving wheels sinks into the carpet, and the rotating blade scrapes dust from the carpet. On the other hand, when cleaning the tatami mat or flooring floor, the suction tool body or moving wheels do not sink, so do not touch the tatami mat or flooring floor with the rotating blades.
Only the rotating brush member touches. Then, the brush member scrapes out the dust on the tatami mat and the flooring and polishes the surface of the dust.

The edge of 41a efficiently scrapes hair and lint from the cleaning surface. Also, when cleaning the tatami mats and floors,
The thin fibers in the pile member 42 of the rotating brush 44 are
Enter the seams of tatami mats and floors to scrape off dust. Further, in this floor suction tool M 3 , since the blade 41, which is heavier than the pile member 42, is provided with the eight cutout portions 41a ... 41a, the weight difference between the two is reduced as compared with the conventional case. Therefore, the rotating brush 4
It is possible to prevent the possibility of generation of large vibrations and noises during rotation of 4.

Moreover, since the brush member of the rotating body has a strong waist due to the bulging portion, the effect of scraping out dust and polishing the surface is great when cleaning the tatami mat or the flooring. Further, since the rotating body is provided with the bulging portion as described above, the weight balance of the rotating brush is adjusted. Moreover, since the floor suction tool of the electric vacuum cleaner according to claim 2 of the present invention is configured as described above, it can be applied to any cleaning surface of a carpet, tatami mat, and flooring floor. In other words, when cleaning the carpet, dust can be efficiently scraped off with the blade, and when cleaning the tatami mat and the floor.
Since the blade does not contact the cleaning surface, there is no risk of damaging the tatami mat and the floor.
