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, and the number of parts increases, and a large amount of outside air is sucked to rotate the turbine, thereby deteriorating dust suction characteristics. It is necessary to rotate the turbine with a small amount of outside air so as not to perform the cleaning operation. Therefore, there is a problem that the rotating force is weak and a good rotating force cannot be obtained when cleaning a surface to be cleaned having a large resistance such as a carpet.
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 formed in a substantially cylindrical shape.
A suction port 2 is formed on the lower surface, and a rotation brush storage chamber 3 in which a rotation brush 8 described later is stored is formed. The rotation brush storage chamber 3 is formed in an arc shape along the rotation locus of the rotation brush 8. ing. Reference numeral 4 denotes an end plate for closing both end openings of the suction tool main body 1, which is provided with a shaft support 6 for rotatably supporting a wheel 5, and which is provided between the suction port 2 and the surface to be cleaned by the wheel 5. Are formed. Reference numeral 7 denotes a support plate fixed to the end plate 4.

Reference numeral 8 denotes a rotary brush which is rotatably supported by the support plate 7 in a state facing the suction port 2 and is disposed in the rotary brush storage chamber 3. And a pair of brush bodies 12 to be mounted by inserting the base 11 into the spiral groove 10 formed in the core 9, and to be mounted by inserting the base 15 into the spiral groove 10 of the core 9. It comprises a pair of blades 13.

The blade 13 includes a cloth 14 and a cloth 14
Base 15 composed of synthetic resin molded at the end of
And a brush-like body 16 sewn to the other end of the cloth-like body 14, and the blade 13 is attached to the cloth-like body 14 by the brush-like body 16.
By sewing, the cloth-like body 14 is pulled and curved. The blade 13 is mounted on the core body 9 so as to be curved backward with respect to the rotation direction of the rotating brush 8.

When the rotation of the rotary brush 8 is stopped, the blade 13 is curved rearward in the rotation direction of the rotary brush 8 as shown in FIG.
When the is rotated, the centrifugal force accompanying the rotation causes it to be in an upright state, as shown in FIG. 4. I have. Further, when the rotary brush 8 is stopped, the brush body 12 and the blade 13 are formed so as not to contact the floor surface even when the suction tool main body 1 is placed on the floor surface.

Reference numeral 17 denotes a guide port formed in the suction tool main body 1 in a longitudinal direction, and guides outside air toward the brush body 12 and the blade 13.

Reference numeral 18 denotes a joint pipe rotatably connected to the suction tool main body 1, which is detachably connected to a cleaner body (not shown) via a flexible hose and an extension pipe.

When the joint pipe 18 is connected to the cleaner body via a flexible hose and an extension pipe, and the cleaner body is driven, air is sucked from the suction port 2. When the suction tool main body 1 is raised from the surface to be cleaned, most of the air is sucked from the suction port 2 because the suction resistance from the suction port 2 is small. In this state, since the suction port 2 is largely open, the flow velocity of the air sucked from the suction port 2 is relatively low,
Therefore, the rotating brush 8 hardly rotates.

When cleaning a floor surface such as a flooring or a tatami mat, the distance between the surface to be cleaned and the suction port 2 is relatively wide, so that the suction resistance from the suction port 2 is small, and almost all Air is sucked in, and almost no air is sucked in from the guide port 17. In this state, the suction port 2
Since the air sucked from the space between the cleaning brush and the surface to be cleaned has a high flow velocity, the air sucked from the suction port 2 and the air sucked from the guide port 17 are removed by the brush body 12 and the blade 13 of the rotating brush 8.
To rotate the rotating brush 8 counterclockwise in FIG.

When the rotating brush 8 is stopped and is rotating at a low speed, as shown in FIG. Thus, the rotating brush 8 is easily rotated.

When the rotating brush 8 rotates at a high speed, the blade
13 is erected by the centrifugal force as shown in FIG. When the suction tool main body 1 is placed on the floor or the tatami in the standing state of the blade 13, the blade 13 comes into contact with the floor or the tatami, and the floor and the tatami are cleaned. Since the blade 13 uses the flexible cloth-like body 14, even if it comes into contact with the floor surface or the tatami mat, the floor surface or the tatami mat is not damaged.

When cleaning a carpet or the like, the suction port 2 is covered with the carpet, the suction resistance from the suction port 2 increases, and the amount of air sucked from the guide port 17 increases. The air sucked from the guide port 17 collides with the brush body 12 and the blade 13,
While rotating the rotating brush 8 counterclockwise in FIG.
By sucking air from the guide port 17, the suction tool main body 1 can be prevented from sticking to a carpet or the like, and the mobility of the suction tool main body 1 can be improved.

At the time of cleaning a carpet or the like, the surface to be cleaned becomes a resistance, and the rotation of the rotary brush 8 is reduced. However, when the rotation of the rotary brush 8 is reduced, the blade 13 is moved with a decrease in centrifugal force. It gradually bends in the rotation direction so as to gradually restore the shape at the time of stop, the contact resistance with the surface to be cleaned decreases, and the rotation speed of the rotating brush 8 increases. By repeating this operation, the rotation speed of the rotating brush 8 is maintained substantially constant.

The blade 13 is formed by sewing a brush-like body 15 on a cloth-like body 14, so that the blade 13 can be configured to be easily bent, and the blade 13 can be bent by centrifugal force using the brush-like body 15 as a weight. The blade 13 can be easily erected, and the blade 13 can be erected and curved even by a slight change in the number of rotations of the rotating brush 8.
Can be maintained substantially constant.

Next, a second embodiment of the present invention will be described in detail with reference to FIGS. 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 21 denotes a suction tool main body, an upper case 22, a lower case.
23, a cover body 24 covering a part of the upper surface of the upper case 22, a rotating tube 25 supported vertically between the upper and lower cases 22, 23, and rotatably supported by the rotating tube 25. It is composed of a joint pipe 26. Reference numeral 27 denotes a suction port formed on the lower surface of the suction tool main body 21, and reference numeral 28 denotes a rotating brush storage chamber formed inside the suction tool main body 21, and a rotary brush 8 similar to that of the first embodiment is used when rotating. Is stored in.

29 is a guide opening formed in the width direction of the upper case 22, 30 is an intake opening formed in the cover 24, 31 is a closing body for closing the intake opening 30, and is used to clean a carpet or the like. When cleaning the surface, for example, when the suction port 27 is closed by the surface to be cleaned, the pressure in the rotary brush storage chamber 28 decreases and the rotary brush storage chamber 28 deforms toward the rotary brush storage chamber 28 side. The brushed body of the rotating brush 8 passes the sucked outside air through the guide port 29.
The outside air collides with the blade 12 and the blade 13.

Reference numeral 32 denotes a suction keeper disposed before and after the suction port 27 of the suction tool main body 21. The suction keeper is formed of a flexible material such as soft rubber.
32 improves the deep suction force. Reference numeral 33 denotes a rear wheel rotatably supported by a rear portion of the suction tool main body 21.

According to the second embodiment of the present invention, on a surface to be cleaned such as a flooring or a tatami mat, the suction resistance from the suction port 27 is small, and the amount of suction from the suction port 27 is large. The pressure in the storage room 28 does not become a large negative pressure. Therefore, the closing body 31 disposed in the intake port 30 does not deform and open the intake port 30. In this state, air sucked from the suction port 27 is applied to the brush body 12 of the rotating brush 8.
The rotating brush 8 is driven to rotate by colliding with the blade 13.

When the surface to be cleaned, such as a carpet, is to be cleaned, the surface to be cleaned closes the suction port 27, so that the pressure in the rotating brush storage chamber 28 decreases, and the closing body 31 Outside air deformed toward the chamber 28 side and taken in through the intake port 30 and the guide port 29 collides with the brush body 12 and the blade 13 to drive the rotary brush 8 to rotate.

In the present embodiment, the closing body 31 is provided at the intake port 30. However, the closing body 31 may be provided at the intake port 29.
In this case, the cover 24 may be omitted.

Next, a third embodiment of the present invention will be described with reference to FIG.
This will be described in detail below. The same parts as those in the second embodiment are denoted by the same reference numerals, and description thereof will be omitted.

Reference numeral 34 denotes a guide opening formed in the upper case 22 of the suction tool main body 1 in the longitudinal direction, and reference numeral 35 denotes a guide rib formed by hanging from the upper case 22. It is formed so as to be guided so as to collide with a front surface to be cleaned.

According to the third embodiment of the present invention, when the joint pipe 26 is connected to the cleaner body via the flexible hose and the extension pipe, and the electric blower of the cleaner body is driven, the suction port 27 is opened.
Air is sucked from. When the suction tool main body 1 is raised from the surface to be cleaned, the suction resistance from the suction port 27 is small.
Most of the air is sucked from the suction port 27. In this state, since the suction port 27 is largely open, the flow rate of the air sucked from the suction port 27 is relatively low, and therefore, the rotating brush 8 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 27 is relatively large.
The suction resistance from the suction port 27 is small, so that most of the air is sucked from the suction port 27 and hardly sucked from the guide port 34. In this state, the air sucked from between the suction port 27 and the surface to be cleaned has a high flow velocity, so that
13 collides with the brush body 12 and the blade 13 of the rotating brush 8, and rotates the rotating brush 8 counterclockwise in FIG.

When cleaning the surface to be cleaned such as a carpet or the like, the suction port 27 is covered with the surface to be cleaned, the intake resistance from the suction port 27 increases, and the amount of air sucked from the guide port 34 increases. .
Since the guide port 34 is formed with a small opening area, the air sucked from the guide port 34 collides with the surface to be cleaned at a high flow rate, 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 34 is guided to the surface to be cleaned by the guide ribs 35, and 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 has collided with the surface to be cleaned further collides with the brush body 12 and the blade 13 and
Is rotated counterclockwise in FIG. In addition, by sucking air from the guide port 34, 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.

In each of the above embodiments, the guide port is formed to be horizontally long in the width direction of the suction tool main body. However, in this configuration, the strength of the suction tool main body is reduced, and in particular, cleaning of a carpet or the like is performed. At this time, the guide opening may be divided into a plurality of guide openings because the peripheral edge of the guide opening may be deformed toward the rotating brush storage chamber and come into contact with the brush body or the blade of the rotating brush to cause a decrease in the rotating force of the rotating brush. Is preferred.

In each of the above embodiments, the blade is formed of a cloth, a base, and a brush, but may be integrally formed of a soft material such as soft rubber.

Next, a rotary brush 36 according to another embodiment of the present invention will be described in detail with reference to FIG.
Is a core body 37, a pair of brush bodies 40 which are mounted by inserting a base 39 into a spiral groove 38 of the core body 37, and a spiral groove of the core body 37.
It comprises a pair of blades 13 similar to those in the above-described embodiment, which are mounted by inserting the base 15 into 38. The blade 13 corrects the cloth body 14 so as not to bend.

The brush body 40 is a relatively hard cloth-like base.
The core 39 is folded by sandwiching the core 41, fixed with an adhesive or the like, and the fixed part is inserted into the groove 38 of the core body 37 and mounted, and is implanted on the free end side of the base 39. The brush body 40 is inclined rearward with respect to the rotation direction of the rotating brush 36.

In the rotating brush 36 of the present embodiment,
The brush body 40 rises and tilts in accordance with the rotation fluctuation similarly to the blade 13 of the above-described embodiment, so that the rotation speed of the rotating brush 36 can be maintained substantially constant.

Further, the brush body may be formed in a curved manner as in the above embodiment, or the blade may be mounted with an inclination. Further, both the brush body and the blade may be mounted in a curved or inclined manner.
