Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a floor suction tool connected to a vacuum cleaner.

[0002]

2. Description of the Related Art Heretofore, as this type of floor suction device, there has been known a floor suction device in which a rotary brush is rotatably supported on a suction device main body and the rotary brush is rotationally driven by an electric motor or a turbine.

[0003] The rotating brush driven by an electric motor has the drawbacks that the electric motor is heavy, the handling is poor, the structure is complicated, the number of parts is increased, and the assembling workability is poor.

[0004] When the rotary brush is driven to rotate by a turbine, the turbine is disposed in a turbine chamber formed in a suction passage from a suction port to a cleaner body, and is rotated by air sucked together with dust. Due to the configuration, there is a problem that dust or the like is entangled in the turbine over a long period of use and the turbine does not rotate properly.

Therefore, in order to solve the above-mentioned drawbacks, turbines are arranged at both ends of a rotating brush in Japanese Patent Application Laid-Open No. 9-28630 (A47L 9/04) or the like, and external clean air is supplied to the turbines. In this case, a turbine is rotated, and the air is sucked into a vacuum cleaner together with the air sucked from a suction port.

However, in this configuration, it is necessary to dispose turbines at both ends of the rotating brush, which increases the number of parts and a large amount of gas is drawn to rotate the turbine. It is necessary to rotate the turbine with a small amount of outside air so as not to lower it, and there is a problem that a sufficient rotational force cannot be obtained when cleaning a surface to be cleaned such as a carpet having a low rotational force.
In addition, a suction port cannot be formed on the lower surface of the turbine storage chamber, and the suction port becomes small with respect to the lateral width of the suction tool main body.

It comprises a pipe 5 and a joint pipe 6 rotatably supported by the rotary pipe 5. Reference numeral 7 denotes a suction port formed on the lower surface of the suction tool main body 1, reference numeral 8 denotes a rotary brush storage chamber formed inside the suction tool main body 1, and a rotary brush 13 described later is rotatably stored therein. The chamber 8 is formed in an arc shape along the rotation locus of the rotating brush 13.

Reference numeral 9 denotes an end plate for closing both ends of the suction tool main body 1, which is formed with a shaft support 11 for rotatably supporting the front wheel 10. The front wheel 10 allows the suction port 7 and the surface to be cleaned. A predetermined interval is formed between them. Reference numeral 12 denotes a support plate fixed to the end plate 9.

Reference numeral 13 denotes a support plate facing the suction port 7.
The rotary brush 12 is rotatably supported by the rotary brush 12 and is disposed in the rotary brush storage chamber 8. The rotary brush 12 has a core 14 and a spiral groove 15 formed in the core 14. And a pair of blades 18 to which the base 20 is inserted and mounted in the spiral groove 15 of the core 14.

The blade 18 includes a cloth 19 and a cloth 19.
Base 20 made of synthetic resin molded at the end of
And a brush-like body 21 sewn to the end of the cloth-like body 19, and by forming the base 20 on the cloth-like body 19, the end of the cloth-like body 19 is deformed so as to undulate, Further brush-like body
By sewing the cloth 21, the cloth 19 is bent as if pulled. The blade 18 is mounted on the core body 14 so as to be curved backward with respect to the rotation direction of the rotating brush 13.

When the rotation of the rotary brush 13 is stopped, the blade 18 is curved rearward in the rotation direction of the rotary brush 13 as shown in FIG.
As shown in FIG. 4, when the rotating member 13 rotates, the centrifugal force of the rotating member 13 causes the brush member 17 to be in an upright state. The diameter of the rotating path in the upright state is larger than that of the brush body 17. ing. Further, when the rotary brush 13 is stopped, the brush
The blade 17 and the blade 18 do not contact the floor.

Reference numeral 22 denotes a guide opening formed in the upper case 2 of the suction tool main body 1 in the longitudinal direction, and 23 denotes a guide rib formed by hanging from the upper case 2. The guide is designed to collide with the surface to be cleaned in front of 13. Reference numeral 24 denotes an air inlet formed in the cover body 4.

Reference numeral 25 denotes a suction keeper disposed before and after the suction port of the suction tool main body 1, which is made of a flexible material such as soft rubber.
This improves the deep suction force. Reference numeral 26 denotes a rear wheel rotatably supported by a rear portion of the suction tool main body 1.

When the joint pipe 6 is connected to the cleaner body via the flexible hose and the extension pipe, and the electric blower of the cleaner body is driven, air is sucked from the suction port 7. When the suction tool main body 1 is lifted from the surface to be cleaned, most of the air is sucked from the suction port 7 because the suction resistance from the suction port 7 is small. In this state, since the suction port 7 is largely open, the flow velocity of the air sucked from the suction port 7 is relatively low, and therefore, the rotating brush 13 hardly rotates.

When cleaning a floor surface such as a flooring or a tatami mat, the space between the surface to be cleaned and the suction port 7 is relatively large.
The suction resistance from the suction port 7 is small, so that most of the air is sucked from the suction port 7 and hardly sucked from the guide port 22. In this state, the air sucked from the space between the suction port 7 and the surface to be cleaned has a high flow velocity.
The air sucked from the air collides with the brush body 17 and the blade 18 of the rotating brush 13, and rotates the rotating brush 13 counterclockwise in FIG.

The blade 18 is curved rearward in the rotation direction of the rotary brush 13 as shown in FIG.
Easy to receive air sucked from the suction port 7
Rotate 13 efficiently.

When the rotating brush 13 rotates at a high speed, the blade
18 is erected by the centrifugal force as shown in FIG. In the upright state of the blade 18, the blade 18 comes into contact with the floor surface or the tatami mat and performs polishing and cleaning. Since the blade 18 uses the easily deformable cloth-like body 19, even if it touches the floor surface or the tatami mat, it does not damage the floor surface or the tatami mat.

When cleaning the surface to be cleaned such as a carpet or the like, the suction port 7 is covered with the surface to be cleaned, the intake resistance from the suction port 7 increases, and the amount of air sucked from the guide port 22 increases. .
Since the guide port 22 has a small opening area, the air sucked from the guide port 22 collides with the surface to be cleaned at a high flow rate, and jumps up dust and the like on the surface to be cleaned, and enters the cleaner body together with the dust. It is sucked. The outside air sucked from the guide port 22 is guided to the surface to be cleaned by the guide ribs 23, collides with the surface to be cleaned at a high flow rate, and efficiently jumps up dust and the like on the surface to be cleaned, thereby improving the dust removal efficiency. The air that collides with the surface to be cleaned further collides with the brush body 17 and the blade 18 and collides with the rotating brush 13.
Is rotated counterclockwise in FIG. In addition, by sucking air from the guide port 22, the suction tool main body 1 can be prevented from sticking to the surface to be cleaned, and the mobility of the suction tool main body 1 can be improved.

When cleaning a carpet or the like, the surface to be cleaned becomes a resistance and the number of rotations of the rotating brush 13 decreases. However, when the rotation of the rotating brush 13 decreases, the blade 18 reduces the centrifugal force. Accompanying this, it gradually curves backward with respect to the rotation direction so as to gradually restore the shape at the time of stop, the contact resistance with the surface to be cleaned is reduced, and the rotation speed of the rotating brush 13 is increased. By repeating this operation, the rotation speed of the rotating brush 13 is maintained substantially constant.

Since the blade 18 is formed by sewing the brush-like body 21 to the cloth-like body 19, the blade 18 can be easily bent, and the blade 18 can be bent by centrifugal force using the brush-like body 21 as a weight. The blade 18 can be easily erected, the blade 18 can be erected and curved even by a slight change in the rotation speed of the rotating brush 13, and the rotation speed of the rotating brush 13 can be maintained substantially constant.

In the above embodiment, the blade 18
Was composed of a cloth body 19, a base 20, and a brush body 21,
It may be formed integrally with a soft material such as soft rubber.

In the above embodiment, the guide port
Although 22 is formed by a horizontally long slit, the lowering of the strength prevents the blade 18 from contacting the upper case 2 due to the deformation of the upper case 2 due to a decrease in the pressure of the rotating brush storage chamber 8 when cleaning a carpet or the like. Therefore, it is preferable that the guide port 22 is divided into a plurality of sections.

Referring to FIG. 8, a rotary brush according to another embodiment of the present invention will be described in detail. The rotary brush 27 is mounted by inserting a base 30 into a core 28 and a spiral groove 29 of the core 28. And a pair of blades 18 similar to those in the above-described embodiment, which are mounted by inserting the base 20 into the spiral groove 29 of the core 28.

The brush body 31 is a relatively hard cloth-like base.
The core 30 is folded by sandwiching the core 32, fixed with an adhesive or the like, and the fixed part is inserted into the groove 29 of the core 28 and mounted, and is implanted on the free end side of the base 30. The brush body 31 is inclined rearward with respect to the rotation direction of the rotating brush 27.

The blade 18 is formed by the same method as in the above embodiment, but is corrected so as not to bend.

In the present embodiment, the brush body 31 rises and tilts in accordance with the rotation fluctuation similarly to the blade 18 of the above-described embodiment, and the rotation speed of the rotary brush 27 can be maintained substantially constant. .

Further, the brush body may be formed in a curved shape as in the above embodiment, and the blade may be attached to the core body at an angle. Further, both the brush body and the blade may be mounted in a curved or inclined manner.
