[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 the turbine on both sides of the rotating brush, and the number of parts increases, and a large amount of outside air is sucked to rotate the turbine, so that the dust suction characteristics deteriorate. It is necessary to efficiently rotate the turbine with a small amount of outside air so as not to cause the problem, and there is a problem that the turbine shape is complicated. 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.

FIG. 1 shows a first embodiment of the present invention.
This will be described in detail below with reference to FIG.

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.

Reference numeral 11 denotes a rotary brush 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 with respect to the rotating 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 at a central portion in the width direction of the suction tool main body 1. 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.

A cover 24 is attached to the lid 4 by a plurality of locking claws 25. The cover 24 covers the upper part of the discharge port 23,
23 is not directly visible from outside. An intake path 26 is formed between the first rib 21, the second rib 22, and the cover body 24, and the intake path 26 is configured so that the width gradually decreases from the guide port 20 toward the discharge port 23.

Reference 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 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 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 floor surfaces such as flooring, tatami mats, etc., since 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 at a position closer to the rotation center 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.

The second rib 22 extends forward from the rotation center of the rotating brush 11 toward the brush body 15 and the blade 16, so that the outside air sucked from the discharge port 23 can be removed from the brush body 15. 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 gradually narrows 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.

The outside air from the guide opening 20 has the fastest flow velocity in the central portion near the rotating pipe 5, and the rotating brush 11 can be efficiently rotated by the outside air particularly from the central portion of the guide opening 20.

Further, by sucking 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. However, 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 configured to 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, a second embodiment of the present invention will be described in detail below with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

Reference numeral 30 denotes a guide port formed at the lower front portion of the suction tool body 1 by positioning the bottom surface in front of the suction port 7 of the suction tool body 1 above the other bottom portion. , And communicates with the suction port 7.

A bumper 31 is sandwiched and fixed between the upper case 2 and the lid 4 and the lower case 3, and is made of a flexible material such as soft rubber. 32 is the bumper 31
The guide port 30 is closed by a closing body formed integrally with the guide port 30.

According to the second embodiment of the present invention, 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 7 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 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 wide, so that suction resistance from the suction port 7 is small, and The pressure does not become large negative pressure. Therefore, the guideway
The closing body 32 closing the 30 does not deform and open the guide port 30. In this state, since the air sucked from between the suction port 7 and the surface to be cleaned has a high flow velocity, the air sucked from the suction port 7 is applied to the brush body 15 of the rotating brush 11 and the blade 16.
And drives the rotary brush 11 to rotate counterclockwise in FIG.

When cleaning the surface to be cleaned such as a carpet, the suction port 7 is covered with the surface to be cleaned, the suction resistance from the suction port 7 increases, and the pressure in the rotary brush storage chamber 8 decreases. As shown in FIG. 7, the closing body 32 deforms toward the suction port 7 side to open the guide port 30, and the outside air sucked through the guide port 30 collides with the brush body 15 and the blade 16 to rotate. Brush 11
Is driven to rotate. Since the outside air sucked from the guide port 30 collides with the brush body 15 and the blade 16 in the process of being sucked toward the rotating pipe 5, the collision force against the brush body 15 and the blade 16 is strong, and the rotating brush 11 Rotate efficiently.

The outside air from the guide port 30 has the fastest flow velocity in the central portion near the rotary pipe 5, and the rotary brush 11 can be efficiently rotated by the outside air particularly from the central portion of the guide port 30.

Further, by sucking the outside air through the guide port 30, 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.

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

Reference numeral 33 denotes a guide port formed in the lid 4 of the suction tool main body 1, and is formed at the center in the width direction of the suction tool main body 1. Numeral 34 denotes a guide rib which is formed to hang down from the lid 4 and guides the outside air sucked from the guide port 33 so as to collide with the surface to be cleaned in front of the rotary brush 11. Reference numeral 35 denotes a cover that covers a portion of the lid 4 where the guide opening 33 is formed with a space between the cover 4 and the ventilation hole 36 that communicates with the guide opening 33 through the space. .

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 7 is lifted from the surface to be cleaned, the suction port 7
Is large, 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, a tatami mat, or the like, since 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 33. 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.
8 collides with the brush body 15 and the blade 16 of the rotating brush 11, and rotates the rotating brush 11 counterclockwise in FIG.

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 33 increases. .
Since the guide opening 33 is formed with a small opening area, the air sucked from the guide opening 33 collides with the surface to be cleaned at a high flow velocity, 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 33 is guided to the surface to be cleaned by the guide ribs 34, 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 colliding with the surface to be cleaned further collides with the brush body 15 and the blade 16 and
Is rotated counterclockwise in FIG. In addition, by sucking air from the guide port 33, 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.

The body 40 is mounted so as to be inclined rearward with respect to the rotation direction of the rotating brush 36.

The blade 16 is formed in the same manner as in the first embodiment, but is corrected so as not to bend.

In this embodiment, the brush body 40 rises and tilts in accordance with the same rotation fluctuation as the blade 16 of the above-described first embodiment, and maintains the rotation speed of the rotary brush 36 substantially constant. be able to.
