Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction tool used by being connected to a cleaner body.

[0002]

2. Description of the Related Art Conventionally, as a suction tool for this kind of bed, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Publication No. 7-67814 (A47L 9/04), it is generally known that a suction port is formed in front of a lower surface of a suction tool body, and a rotary brush faces the suction port.

However, in the conventional floor suction tool, since the suction port is only formed at the front side, especially when cleaning the velvet and the like, if the same place is not cleaned many times, the velvet is not cleaned. It was not possible to reliably remove the lint and the like entangled in the hairs, which was one factor that made the user feel that cleaning was troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a floor suction tool capable of improving cleaning efficiency.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a suction body, which is composed of an upper case and a lower case, and has a first suction port 2 formed in the front of the lower surface and a second suction port 3 formed in the rear of the lower surface. Reference numeral 4 denotes a connecting pipe pivotably supported between the first suction port 2 and the second suction port 3 of the suction tool body 1 and extending toward the rear side of the suction tool body 1.
It is adapted to be connected to the cleaner body via an extension pipe and a flexible hose (not shown). 5 is the suction tool body 1
The first suction port 2 and the second suction port 3 are communicated with the connecting pipe 4 by an air passage formed inside.

Reference numeral 6 denotes a first rotating brush which faces the first suction port 1 and is rotatably supported by the suction tool body 1, and has a plurality of blades 7 made of rubber. The blade 7 is
The front end of the blade 7 is formed to have a length above the imaginary line connecting the lowermost positions of the front wheel 18, the rear wheel 19, and the auxiliary wheel 20, which will be described later.

Reference numeral 8 is a second rotating brush which is rotatably supported by the suction tool body 1 so as to face the second suction port 3 and which is composed of a plurality of rubber blades 9 and is softer than the blades 9 and dust collecting. It has a wiping blade 10 which is an auxiliary blade made of a cloth or non-woven fabric having a collecting property. The blade 9 is formed to have a length such that the tip of the blade 9 is located above a virtual line connecting the lowermost positions of a front wheel 18, a rear wheel 19 and an auxiliary wheel 20, which will be described later. Take blade 10

Reference numeral 11 denotes an electric motor built in the suction tool body 1 for rotating the first rotating brush 6 via the belt 12 and rotating the second rotating brush 8 via the gears 13, 14 and the belt 15. The first rotary brush 6 and the second rotary brush 8 are in opposite directions to each other. In the present embodiment, the first rotary brush 6 and the second rotary brush 8 are connected to the suction tool body 1
Of the first rotating brush 6 and the second rotating brush 8 in the clockwise direction as shown by the arrow in FIG. 1, so that the first rotating brush 6 and the second rotating brush 8 are scratched. The dust and the like that have been raised are scattered toward the ventilation path 5.

Reference numeral 16 denotes a control board for controlling the electric motor 11, 17
Is a safety switch that stops the electric motor 11 when the suction tool body 1 is lifted from the surface to be cleaned.

Reference numeral 18 is a front wheel rotatably supported on both front sides of the lower surface of the suction tool body 1, 19 is a rear wheel rotatably supported on both rear surfaces of the lower surface of the suction tool body 1, and 20 is the suction tool. An auxiliary wheel rotatably supported between the first suction port 2 and the second suction port 3 at the center of the lower surface of the main body 1, and the amount of protrusion of each wheel 18, 19, 20 from the bottom surface of the suction tool main body 1 is approximately Formed the same.

When cleaning a surface to be cleaned such as a flooring, dust or the like is sucked from the first suction port 2 and the second suction port 3 as shown in FIG. Since the blade 7 of the first rotating brush 6 and the blade 9 of the second rotating brush 8 are formed to have a length that does not contact the surface to be cleaned, the blades 7 and 9 rub the surface to be cleaned and scratch the surface to be cleaned. There is no. On the other hand, the scraping blade 10 of the second rotating brush 8 is formed to have a length in contact with the surface to be cleaned, and the rotation of the second rotating brush 8 wipes off dust and oil stains attached to the surface to be cleaned. Scratch out dust, sand, etc. that have entered gaps such as flooring.

When cleaning a surface to be cleaned such as a carpet,
As shown in, each wheel 18, 19, 20 is buried in the vine, the blade 7 of the first rotary brush 6 and the blade 9 of the second rotary brush 8 contact the surface to be cleaned, and the first rotary brush 6 and the second rotary brush 6 rotate. The rotation of the brush 8 scrapes up thread waste and the like entwined with the velvet and the like. Since the first rotary brush 6 and the second rotary brush 8 simultaneously scrape up lint and the like, the scraping effect is increased as compared with the conventional case, and it is not necessary to clean the same place many times, and the cleaning efficiency is improved.

It is known that the rotating brush increases the scraping effect by rotating in the direction in which the suction tool body 1 is prevented from advancing, but in the present embodiment, the first rotating brush 6 and the second rotating brush 6 are used. Since the rotating brushes 8 are rotated in the opposite directions, the scraping effect of one of the rotating brushes is increased and the cleaning efficiency can be improved regardless of whether the suction tool body 1 is moving forward or backward. . Further, since the first rotating brush 6 and the second rotating brush 8 are rotated in the direction of scattering the scraped dust and the like toward the ventilation passage 5, the dust does not leak to the outside of the suction tool body 1. , Can be reliably collected.
