Abstract

PROBLEM TO BE SOLVED: To efficiently drive a rotary brush with a simple structure and to improve cleaning workability by forming a guide port sucking the outside air into a rotary brush storage chamber on a suction tool main body, and forming a guide guiding the outside air sucked from the guide port to the blade of the rotary brush. SOLUTION: When the electric blower of a cleaner main body is driven, air suction force is applied to a suction port 7 via a suction hose. When the floor surface is cleaned, the interval between the cleaned surface and the suction port 7 is wide, suction resistance is small, most of the air is sucked from the suction port 7, and a small amount of air is sucked from a guide port 20 formed at the upper section of a suction tool main body. A rotary brush 11 is rotated by the air stream sucked from the suction port 7. When a carpet is cleaned, the suction resistance from the suction port 7 is increased, and the air quantity sucked from the guide port 20 is increased, thereby the rotary brush 11 is efficiently rotated by a fast air stream sucked from a discharge port 23 having a small opening area.

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 used in connection with a vacuum cleaner.

[0002]

2. Description of the Related Art Heretofore, there has been known a floor suction tool of this type in which a rotary brush is rotatably supported on a suction tool body and the rotary brush is driven to rotate by an electric motor or a turbine. When the rotating brush is driven to rotate by an electric motor, the electric motor is heavy, the handling property during cleaning operation is poor, the number of parts is increased, and the assembling workability is poor.
There were drawbacks such as becoming expensive.

[0003] 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 is clogged in the turbine due to long-term use, and the turbine does not rotate properly.

Therefore, in order to solve the above-mentioned drawback, turbines are arranged at both ends of a rotating brush as disclosed in Japanese Patent Application Laid-Open No. 9-28630 (A47L 9/04), 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, since the turbines are provided on both sides of the rotating brush, the number of parts increases, and it is necessary to efficiently rotate the turbine with a small amount of outside air in order to suppress a reduction in dust suction characteristics. There is a problem that the turbine shape is complicated. Also, an intake port cannot be formed on the lower surface of the turbine storage chamber,
There is a drawback that the suction port becomes smaller than the width of the suction tool main body, so that dust and the like are left unsucked.

FIG. 1 shows a first embodiment of the present invention.
7 will be described in detail below.

Reference numeral 1 denotes a suction tool main body, an upper case 2, a lower case 3, a lid 4 removably engaged with the upper case 2 and the lower case 3, and a vertically movable member between the upper and lower cases 2, 3. It is composed of a rotating pipe 5 supported and a joint pipe 6 rotatably supported by the rotating pipe 5.

Reference numeral 7 denotes a suction port formed in the bottom surface of the suction tool main body 1, and reference numeral 8 denotes a rotary brush storage chamber formed in the suction tool main body 1.

Numerals 9 are shaft supports formed on both sides of the suction tool main body 1, and rotatably support wheels 27 described later. Ten
Is a rib defined from the upper and lower cases 2 and 3 of the suction tool main body 1 to partition the shaft support 10 and the rotary brush storage chamber 8, and the outside air is supplied to the rotary brush storage chamber 8 via the shaft support 10. Prevents suction.

A rotary brush 11 is rotatably stored in the rotary brush storage chamber 8 in a state facing the suction port 7.
The rotating brush 11 includes a core body 12, a pair of brush bodies 15 which are mounted by inserting a base 14 into a spiral groove 13 formed in the core body 12, and a spiral groove of the core body 12. It is composed of a pair of blades 16 inserted into the base 13 and mounted.

The blade 16 comprises a cloth 17 and the cloth
Base made of synthetic resin molded at the end of 17
And a brush-like body 19 sewn to the end of the cloth-like body 17
By forming the base 18 on the cloth-like body 17, the end of the cloth-like body 17 is deformed so as to undulate, and further, the brush-like body 19 is sewn to the end of the cloth-like body 17. As a result, the cloth 17 is bent as if pulled. The blade 16 is mounted on the core 12 so as to be curved rearward with respect to the rotation direction of the rotating brush 11.

The blade 16 is curved rearward in the rotation direction of the rotating brush 11 as shown in FIG. 4 when the rotating brush 11 is in the rotation stopped state and the low-speed rotating state. In the high-speed rotation state, a centrifugal force accompanying the rotation causes the robot to be in an upright state as shown in FIG.
The diameter of the rotation locus of the brush body 15 is larger than that of the brush body 15. When the rotary brush 11 is stopped, the suction tool main body 1
The brush body 15 and the blade 16 are formed so as not to come into contact with the floor surface even if the brush member is placed on the floor surface.

Reference numeral 20 denotes a guide port formed on the upper surface of the lid 4 and is formed over substantially the entire width of the brush body 15 and the blade 16 of the rotary brush 11. Reference numeral 21 denotes a first rib formed on the front side of the guide port 20, and constitutes a guide for guiding outside air sucked from the guide port 20 to the brush body 15 and the blade 16 of the rotating brush 11. The first rib 21 is formed so as to hang down from the rear surface of the lid 4 at a position closer to the rotation center of the rotary brush 11 than the foremost position of the rotation locus of the blade 16 and is located within the projection range of the rotation locus. It extends below the highest position of the 15 rotation trajectories.

Reference numeral 22 denotes a second rib formed on the rear side of the guide port 20.
And a guide leading to the brush body 15 and the blade 16. The second rib 22 extends forward from the center of rotation of the rotary brush 11, and a discharge port 23 is formed between the tip of the first rib 21 and the second rib 22.

Reference numeral 24 denotes a cover attached to the lid 4 by a locking claw 25, which covers the upper portion of the discharge port 23 so that the discharge port 23 is not directly visible from outside. The first rib 21,
An intake path 26 is formed between the second rib 22 and the cover 24, and the intake path 26 is configured so that the width gradually decreases from the guide port 20 to the discharge port 23.

Numeral 27 denotes a front wheel mounted on the shaft support 9.
The suction tool main body 1 is formed to have substantially the same diameter as the outer diameter. 28 is a rear wheel pivotally supported by the rear part of the suction tool main body 1, 29 is a suction keeper disposed before and after the suction port 7, and is formed of a flexible material such as soft rubber. The suction keeper 29 improves the deep suction force.

When the joint pipe 6 is connected to the cleaner main body via the flexible hose and the extension pipe, and the electric blower of the cleaner main body is driven, air is sucked from the suction port 7. When the suction tool body 1 is lifted from the surface to be cleaned, the suction port 7
Most of the air is sucked in from the suction port 7 because the suction resistance from the suction port 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 11 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 7. 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 15 and the blade 16 of the rotating brush 11, and rotates the rotating brush 11 counterclockwise in FIG.

The blade 16 is curved rearward with respect to the rotation direction of the rotating brush 11 as shown in FIG. The rotating brush 11 is efficiently rotated, and the rotating brush 11 rotates efficiently.

When the rotating brush 11 rotates at high speed, the blade
16 is erected by the centrifugal force as shown in FIG. In the upright state of the blade 16, the blade 16 comes into contact with the floor surface or the tatami mat and performs polishing and cleaning. Since the blade 16 uses the easily deformable cloth-like body 17, even if it touches the floor surface or the tatami mat, the floor surface or the tatami mat is not damaged.

When cleaning the surface to be cleaned, such as a carpet, 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 outside air sucked from the guide port 20 increases. .
Since the discharge port 23 has an opening area much smaller than that of the suction port 7, the air sucked from the discharge port 23 collides with the brush body 15 and the blade 16 of the rotating brush 11 at a high flow rate, and Rotate 11 counterclockwise in FIG.

The first rib 21 is formed so as to hang down from the foremost position of the rotation locus of the blade 16 on the rotation center side of the rotating brush 11 and extend below the highest position of the rotation locus of the brush body 15. Thus, it is possible to prevent the outside air sucked from the discharge port 23 from sneaking into the front of the rotating brush 11 without colliding with the brush body 15 or the blade 16 and to reliably guide the outside air to the brush body 15 and the blade 16, 11 can be driven to rotate efficiently.

Since the second ribs 22 extend forward from the rotation center of the rotating brush 11 toward the brush body 15 and the blade 16, the outside air sucked from the discharge port 23 can remove the outside air. In addition, it is possible to prevent the rotary brush 11 from being directly sucked into the rotary tube 5 by passing over the rotary brush 11 without contacting the blade 16 and to reliably guide the rotary brush 11 to the brush body 15 and the blade 16. It can be driven to rotate efficiently.

Since the intake path 26 for guiding the outside air from the guide port 20 to the discharge port 23 is configured so as to be gradually narrowed toward the discharge port 23, generation of noise due to a change in the area of the ventilation path is reduced. And the brush body 15 and the blade from the discharge port 23.
The rotation efficiency of the rotating brush 11 can be improved by increasing the flow velocity of the outside air that collides with the 16.

Further, by sucking the air from the guide port 20, 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 rotation speed of the rotating brush 11 decreases, but as the rotation speed of the rotating brush 11 decreases, the blade 16 reduces the centrifugal force. As a result, it gradually curves backward with respect to the rotation direction so as to restore the shape at the time of stop, and the contact resistance with the surface to be cleaned is reduced and the rotation speed is increased. By repeating this operation, the rotation speed of the rotating brush 11 is maintained substantially constant.

Since the blade 16 is formed by sewing the brush-like body 19 to the cloth-like body 17, the blade 16 can be easily bent, and the blade 16 can be bent by centrifugal force using the brush-like body 19 as a weight. The blade 16 can be easily erected, the blade 16 can be erected and curved even by a slight change in the rotation speed of the rotating brush 11, and the rotation speed of the rotating brush 11 can be maintained substantially constant.

In the above embodiment, the blade 16
Was composed of a cloth-like body 17, a base 18, and a brush-like body 19,
It may be formed integrally with a flexible material such as soft rubber.

In the above embodiment, the intake passage
26 is formed by a horizontally elongated slit, but the strength of the lid 4 is reduced, and the lid 4 is deformed toward the rotary brush storage chamber 8 due to a decrease in the pressure of the rotary brush storage chamber 8 when cleaning a carpet or the like. In order to prevent the brush body 15 and the blade 16 from coming into contact with the first rib 21 and the second rib 22, it is preferable that the intake path 26 be formed in a plurality of parts.

Next, another embodiment of the present invention will be described in detail with reference to FIG. Note that the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

Reference numeral 31 denotes a guide port formed over substantially the entire width of the brush body 15 and the blade 16 of the rotary brush 11, and is configured to suck outside air into the rotary brush storage chamber 8. Reference numeral 32 denotes a first rib formed on the front side of the guide port 31.
A guide for guiding the outside air sucked from 31 to the brush body 15 and the blade 16 of the rotating brush 11 is configured. The first rib
32 is formed within the projection range of the rotation trajectory from the back surface of the lid 4 to the rotation center side of the rotating brush 11 from the foremost position of the rotation trajectory of the blade 16, and is located within the projection range of the rotation trajectory. Extends below the highest position.

Reference numeral 33 denotes a second rib formed on the rear side of the guide opening 31.
And a guide leading to the brush body 15 and the blade 16. The second rib 33 extends in the tangential direction of the rotation trajectory of the brush body 15 and the blade 16, and has a tip located forward of the rotation center of the rotating brush 11. A discharge port 34 is formed between the two ribs 33 and the tip.

In this embodiment, the first rib 32 is
The brush 16 is formed so as to hang down from the foremost position of the rotation trajectory of the blade 16 at a position closer to the rotation center of the rotating brush 11 and extend below the highest position of the rotation trajectory of the brush body 15, so that the outside air from the discharge port 34 The rotating brush 11 can be prevented from sneaking in front of the rotating brush 11 without colliding with the body 15 and the blade 16, and can be reliably guided to the brush body 15 and the blade 16, so that the rotating brush 11 can be driven to rotate efficiently.

The second rib 33 extends forward from the center of rotation of the rotating brush 11 toward the brush body 15 and the blade 16, so that the outside air from the discharge port 34 can be removed from the brush body 15 and the blade 16. 16 can be prevented from being directly sucked into the rotating tube 5 by passing over the rotating brush 11 without contacting the rotating brush 11, and can be reliably guided to the brush body 15 and the blade 16, so that the rotating brush 11 can be efficiently used. It can be driven to rotate. Further, the second rib 33 is provided with the brush body 15 and the blade 16.
Since it is formed to be inclined in the tangential direction of the rotation trajectory, the outside air can be more efficiently guided to the brush body 15 and the blade 16, and the rotation efficiency of the rotating brush 11 can be improved.

The interval between the first rib 32 and the second rib 33 is configured so as to gradually narrow toward the discharge port 34, so that the generation of noise due to a change in the area of the ventilation path is reduced, and The rotation efficiency of the rotating brush 11 can be improved by increasing the flow velocity of the outside air that collides with the brush body 15 and the blade 16 from the discharge port 34.
