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, as a floor suction tool of this type, there has been known a suction tool which rotatably supports a rotary brush on a suction tool body and drives the rotary brush 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 and the handling is not easy during the cleaning operation, the number of parts is increased, and the assembling workability is poor and expensive.

[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, dust may be clogged in the turbine and the turbine may not rotate properly due to long-term use.

Further, Japanese Patent Application Laid-Open No. 9-28630 (A
47L 9/04) The turbines are arranged at both ends of the rotating brush at the both ends of the rotating brush, the external clean air is supplied to the turbine to rotate the turbine, and the air is sucked into the vacuum cleaner together with the air sucked from the suction port. Some suggestions have been made.

[0006]

The functions of the above-mentioned rotary brush include a function of punching out dust such as lint on a carpet and a function of scraping the dust. However, it is difficult to absorb the lint and the like buried in the carpet with deep hairs at a time by one operation of the floor suction tool. First, the lint and the litter buried in the carpet in the first operation are difficult. Is hit and floated on the surface side of the carpet, and dust such as lint and the like floating on the surface side is scraped off and sucked in the second operation. Therefore, to clean dust such as lint on the carpet is much more troublesome than cleaning the floor such as flooring.

Further, the floor suction tool is moved forward and backward for cleaning. On a carpet, when the rotating direction of the rotating brush is opposite to the advancing direction of the floor suction tool, the moving direction of the tip portion of the rotating brush is changed. Since the relative traveling direction of the surface to be cleaned is reversed,
The efficiency of collecting dust such as lint is improved. On the other hand, when the rotating direction of the rotating brush is the same as the moving direction of the floor suction tool, the moving direction of the tip portion of the rotating brush and the relative moving direction of the surface to be cleaned are the same, so that dust such as lint is removed. Collection efficiency does not increase much. Therefore, even if the floor suction tool is moved back and forth,
There was a problem that the collection efficiency did not increase so much in one direction.

Accordingly, the present invention has been made to solve such a problem, and it is intended to strike out dust such as lint or the like buried in a deeply cleaned surface of a carpet or the like by a single operation. It is an object of the present invention to provide a floor suction tool that can be scraped off.

It is another object of the present invention to provide a floor suction tool which can be cleaned with a high collection efficiency in any of the front and rear directions.

It is another object of the present invention to realize the floor suction tool as described above with a configuration as simple as possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS.

As shown in FIG. 1 and the like, the suction tool main body 1 of the present embodiment comprises an upper case 2, a lower case 3, a lid 4 detachably mounted on the upper case 2 and the lower case 3, It comprises a rotating tube 5 rotatably supported in the vertical direction between the cases 2 and 3, and a joint tube 6 rotatably supported in the circumferential direction of the rotating tube 5.

A suction port 7 is formed on the bottom surface of the suction tool main body 1 over substantially the entire width in the longitudinal direction, and two rotary brushes 11a and 11b described later are rotatably housed in the suction tool main body 1. Rotating brush storage room 8 with a substantially oval cross section
Are formed.

As shown in FIG. 2, on both sides in the longitudinal direction of the suction tool main body 1, there is formed a cylindrical shaft support 9 for rotatably supporting a front wheel 28 described later. A partition rib 10 erected from the lower case 3 and hung from the lid 4 is located inside these two shaft supports 9.
And the rotary brush storage chamber 8, and the outside air is prevented from being sucked into the rotary brush storage chamber 8 through the cylindrical shaft support 9.

The first rotating brush 11a on the front side and the second rotating brush 1 on the rear side
1b are rotatably housed so as to face the suction port 7, respectively. These first and second rotating brushes 11
a and 11b have the same configuration, and as shown in FIG. 1, a core body 12 and a pair of brush bodies which are mounted by inserting a base 14 into a spiral groove 13 formed in the core body 12, respectively. 1
5 and a pair of blades 16 which are also mounted by inserting the base 18 into the spiral groove 13 of the core 12.

Each of the cores 12 is formed by extruding aluminum and has four grooves 13 arranged at equal intervals.
Are formed in a helical shape such that they are shifted from each other by about 90 degrees. Therefore, the brush body 15 and the blade 16 inserted into these grooves 13 also have a similar spiral shape. Further, the pair of brush bodies 15 and the blades 16 are arranged so that the same kind of brush bodies and the blades are symmetrically located at 180 ° apart from each other, so that the balance at the time of rotation is improved and the rotation is smooth. .

The brush body 15 is formed of nylon or polyethylene resin, and the length up to the tip is such that the tip reaches the tip of the carpet to be sucked when cleaning a carpet with long hair. , Are formed shorter than the blade 16 described below.

On the other hand, the blade 16 includes a cloth 17 having a fine texture that is hard to pass air, a base 18 formed by molding a synthetic resin at one end of the cloth 17, and the cloth 17. Brush-like body 1 sewn to the other end (tip) of the brush
9. The cloth-like body 1 is formed by forming a base 18 molded with a synthetic resin on the cloth-like body 17.
7 is deformed so as to undulate, and further, a brush-like body 19 is sewn to the tip of the cloth-like body 17 so that the cloth-like body 1
7 is bent to one side 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 each of the rotating brushes 11a and 11b (both clockwise in the drawing).

The blade 16 is provided with each rotating brush 11
In the rotation stopped state and the low-speed rotation state of the rotating brushes 11a and 11b, the rotating brushes 11a and 11b are curved backward with respect to the rotating direction (clockwise in the drawing), but the rotating brushes 11a and 11b rotate at a high speed. When the brush body 15 is in the state, the centrifugal force accompanying the rotation causes the brush body 15 to be in an upright state as shown in FIG.
Is formed so as to have a diameter larger than the diameter of the rotation trajectory and to contact a floor surface such as a flooring. When the rotary brushes 11a and 11b are stopped, the brush body 15 and the blade 16 are formed so as not to contact the floor surface even when the suction tool main body 1 is placed on the floor surface.

On the other hand, a brush body 15 of the second rotary brush 11b and a blade 1
6 is formed with a guide port 20 extending over substantially the entire width in the longitudinal direction. External air sucked from the guide port 20 is supplied to the brush body 15 of the second rotating brush 11b in front of the guide port 20.
And a first rib 21 constituting a guide leading to the blade 16
a is formed. The first rib 21a is formed so as to hang from the back surface side of the lid 4 slightly toward the rotation center from the forefront position of the rotation path of the brush body 15 and the blade 16 of the second rotating brush 11b, and the maximum rotation path of the blade 16 It is extended to a position where it does not contact with.

Also, a second rib 21b is formed on the rear side of the guide opening 20. The second rib 21b serves as a guide for guiding outside air sucked from the guide opening 20 to the brush body 15 and the blade 16 of the second rotary brush 11b. ing. This second rib 21b
Is extended from the center of rotation of the second rotating brush 11b to the front side, and the tip is bent downward.
The discharge port 22 is formed between the tip of the rib 21a and the second rib 21b. The upper portion of the discharge port 22 is covered with the lid 4 so that the discharge port 22 is not directly visible from outside.

The above-described guide port 20, first rib 21a and second rib 21b form an intake path 23, and the intake path 23 is configured so as to become narrower from the guide port 20 toward the discharge port 22. I have.

As shown in FIG. 4, the lid 4 on which the guide opening 20 and the like are formed can be removed by operating the knobs 4a provided on both sides of the rear portion outward. When the body 4 is removed, as shown in FIG. 2, the rotating brushes 11a and 11b can be maintained.

On the other hand, on the front side of the lower case 3, the first
Of the rotating brush 11a, a slit-shaped intake port 24 is formed over substantially the entire width of the brush body 15 and the blade 16 in the longitudinal direction. On the upper side of the intake port 24, the outside air sucked from the intake port 24 passes below the rotation center of the first rotating brush 11a, and the brush body 15 and the blade 1
A guide rib 25 is formed to form a guide that guides the guide 6. The guide rib 25 is bent obliquely downward so as to prevent the outside air sucked from the intake port 24 from slightly going above the rotation center of the first rotating brush 11a.

A suction keeper 30, which will be described later, is attached to the lower side of the suction port 24. The inside of the suction keeper 30 is lowered by one step to form a front edge 7a of the suction port 7, and this front edge 7a extends horizontally. The outside air, which is secured for a fixed width and is sucked from the intake port 24, is supplied to the first rotating brush 11a.
Of the brush body 15 and the blade 16. The horizontal upper surface of the suction port front end edge 7a is located slightly above the lowermost position of the rotation trajectory of the brush body 15 and the blade 16 of the first and second rotating brushes 11a and 11b. A discharge port 26 is formed between the guide rib 25 and the tip. Therefore, the horizontal upper surface of the suction port front end edge 7a directs the intake air obliquely directed downward by the upper guide ribs 25 toward the suction port of the rotary pipe 5 in the horizontal direction. The second rotating brush 11b is brought into contact with the brush body 15 and the blade 16 of the brush 11a, and is further brought into contact with the brush body 15 and the blade 16 of the second rotating brush 11b, which is rotationally driven by the outside air sucked from the guide port 20. It is configured to further increase the rotation speed of the motor 11b.

An intake passage 27 is formed by the intake port 24, the guide rib 25 and the front edge 7a of the intake port 7, and the intake path 27 is configured so as to become narrower from the intake port 24 toward the discharge port 26. Have been.

On the other hand, the front wheel 2 mounted on the shaft support 9
Numeral 8 is formed to have substantially the same diameter as the outer shape of the front side of the suction tool main body 1 having a substantially semicircular cross section. On the other hand, a small-diameter rear wheel 29 is rotatably supported at the rear of the suction tool main body 1. Further, a suction keeper 30 made of soft rubber or the like is provided before and after the suction port 7, and the suction keeper 30 improves a deep suction force. Further, a bumper 31 made of soft rubber or the like is provided on the forefront of the suction tool main body 1, and even if the bumper 31 hits a wall or furniture during cleaning, the wall, furniture, and the suction tool main body 1 itself are provided. Can be prevented from being damaged.

When the above-described joint pipe 6 of the suction tool main body 1 is connected to a cleaner main body (not shown) via a flexible hose and an extension pipe, and the electric blower of the cleaner main body is driven, the suction port 7 is opened. Air is sucked. 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,
Therefore, each of the rotating brushes 11a and 11b hardly rotates.

When cleaning a floor surface such as a flooring or a tatami mat, the clearance between the surface to be cleaned and the suction port 7 is relatively wide, so that the suction resistance from the suction port 7 is relatively small.
And almost no air is sucked from the upper surface guide port 20 or the front air inlet port 24.
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 hits the brush body 15 and the blade 16 of each of the rotating brushes 11a and 11b, and Rotating brushes 11a and 11b are shown in FIG.
Rotate clockwise.

In this case, the brush body 15 is easy to allow air to pass through. However, since the brush body 15 is formed so as not to be in contact with the floor surface such as a flooring, the rotating brushes 11 are not a little.
It functions to rotate a and 11b. Meanwhile, blade 1
6 indicates that the rotating brushes 11a and 11b are in a rotation stopped state or a low-speed rotating state as described above.
Since it is curved rearward with respect to the rotation direction of a and 11b, it is easy to receive the air sucked from the suction port 7, and it is difficult to pass the air by using the cloth 17 having a fine texture. The rotating brushes 11a and 11b rotate efficiently.

When the rotating brushes 11a and 11b rotate at a high speed, the blade 16 rises as shown in FIG. 1 by centrifugal force. In the upright state of the blade 16, the brush-like body 19 sewn to the tip of the cloth-like body 17 comes into contact with the floor surface or the tatami mat surface, and the two rotary brushes 11a and 11b perform wiping and polishing. Can be done quickly. Blade 1
6 uses the easily deformable cloth-like body 17, so that even if it touches the floor surface or the tatami surface, it does not damage the floor surface or the tatami surface.

On the other hand, 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 upper surface guide port 20 and the front intake port 24 are cleaned.
The amount of outside air sucked from the air increases. Their respective outlets 2
Since the openings 2 and 26 have an extremely small opening area as compared with the intake port 7, the air sucked from each of the discharge ports 22 and 26 can be supplied to the corresponding rotary brush at a higher flow rate than the above-described intake port 7. The rotating brushes 11a and 11b collide with the brush bodies 15 and the blades 16 of the rotating brushes 11a and 11b, respectively, and are rotated as shown in FIG.
Rotate clockwise.

Here, the first rib 21a located on the front side of the discharge port 22 corresponding to the second rotating brush 11b is provided with the rotation locus of the brush body 15 and the blade 16 of the second rotating brush 11b as described above. Since it is formed so as to hang slightly near the center of rotation from the forefront position, it is possible to prevent outside air sucked from the discharge port 22 from sneaking forward of the second rotating brush 11b without colliding with the brush body 15 or the blade 16. Thus, the second rotating brush 11b can be efficiently rotated and driven.

Similarly, the second port located behind the discharge port 22
The ribs 21b also extend from the rotation center of the second rotating brush 11b to the front side and are bent downward, so that the external air sucked from the discharge port 22 can remove the brush body 15 and the blade 1
6 can be prevented from being directly sucked into the rotating tube 5 by passing over the second rotating brush 11b without colliding with the second rotating brush 11b, and can be reliably guided to the brush body 15 and the blade 16.
The second rotating brush 11b can be driven to rotate efficiently.

The outside air from the guide port 20 is discharged to the discharge port 22.
The intake passage 23 leading to the discharge port 22 is configured to be narrower toward the discharge port 22.
The rotation efficiency of the second rotating brush 11b can be improved by increasing the flow velocity of the outside air colliding with the blade 5 and the blade 16.

Further, since the suction passage 23 has the guide port 20 on the upper surface of the lid 4, even when cleaning the side of the wall, the suction is not blocked by the wall or the like. The rotating force can always be applied to the body 15 and the blade 16 at a good flow rate.

On the other hand, since the guide rib 25 located above the discharge port 26 corresponding to the first rotary brush 11a is bent obliquely downward as described above, the outside air sucked from the discharge port 26 Of the first rotating brush 11a from rotating above the rotation center of the first rotating brush 11a.
Of the rotating brush 11a in the reverse direction (counterclockwise in the drawing) can be prevented from acting as a brake.

The horizontal upper surface of the suction port front edge 7a located below the discharge port 26 is located at the lowermost position of the rotation locus of the brush body 15 and the blade 16 of the first and second rotary brushes 11a and 11b. Because it is located slightly above, it is possible to prevent the outside air sucked from the discharge port 26 from passing directly below without being colliding with the brush body 15 or the blade 16 and being directly sucked into the rotating pipe 5 to ensure the reliability. Can be guided to the brush body 15 and the blade 16 of the first and second rotating brushes 11a and 11b. Therefore, the first rotating brush 11a can be efficiently rotated and driven, and the second rotating brush 11b rotating by the intake air from the discharge port 22 is accelerated to increase its rotation speed (rotational force). Can be increased, and the efficiency of collecting dust such as lint by the second rotating brush 11b can be further increased.

Also, since the intake path 27 for guiding the outside air from the intake port 24 to the discharge port 26 is configured to be narrower toward the discharge port 26, the brush body 15 and the blade The rotation efficiency of the first and second rotating brushes 11b can be improved by increasing the flow velocity of the outside air that collides with the rotating brush 16.

Further, the outside air sucked from the intake passage 27 collides from the front with the brush body 15 and the blade 16 at a position where the brush body 15 and the blade 16 are in contact with the surface to be cleaned such as a carpet or the like, so that the air is pushed out in the rotational direction at the time of contact. Therefore, it is possible to efficiently suppress a decrease in the rotation speed due to the contact.

Even if the intake port 24 is formed on the front surface as described above, the intake is blocked by the wall surface or the like when the wall or the like is cleaned because the bumper 31 protrudes in front of the intake port 24. Therefore, the rotational force can always be applied to the brush bodies 15 and the blades 16 of the first and second rotary brushes 11a and 11b at a favorable flow velocity.

As a secondary effect, the intake paths 23 and 2
By sucking the outside air from 7, the suction tool main body 1 can be prevented from being excessively sucked on 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 as described above,
The surface to be cleaned having a long bristle becomes a resistance so that each rotating brush 11
Although the rotation speeds of a and 11b may decrease, as described above, the outside air sucked from the intake passage 27 is moved from the front to the brush body 15 and the blade 16 at positions where they come into contact with the surface to be cleaned such as a carpet. Since it collides and acts so as to be pushed in the rotation direction at the time of contact, it is possible to suppress a decrease in the number of rotations due to the contact. Still, rotating brushes 11a, 11b
When the number of rotations of the blades decreases, the blades 16 are curved rearward in the rotation direction so as to gradually restore the shape at the time of stop with a decrease in centrifugal force, and the contact resistance with the surface to be cleaned is reduced. The rotation speed decreases and increases. By repeating this operation, the rotation speeds of the rotating brushes 11a and 11b are maintained substantially constant.

That is, 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 brush-like body 19 is used as a weight by centrifugal force. The blade 16 can be easily raised, and each of the rotating brushes 11a, 11
The blade 16 stands up even by a slight change in the number of rotations of b.
Each rotating brush 11a, 1
1b can be kept substantially constant.

As described above, the first and second rotating brushes 11a and 11b rotate in the same direction (both clockwise in FIG. 1), and the respective brush bodies 15 and blades 1 are rotated.
6 allows dust such as lint on the carpet to be beaten out or scraped off and sucked. Here, since the front floor suction tool is provided with the two front and rear rotating brushes 11a and 11b, even dust such as lint buried in a carpet having a thick bristle can be disposed on the front side in the traveling direction of the floor suction tool. It is beaten out with a rotating brush 11a (rotating brush 11b at the time of a pulling operation in the case of a pushing operation) and floated on the surface side of the carpet. Since it can be scraped off, dust such as lint on the carpet can be cleanly cleaned by a single operation.

Further, without using an electric motor or a turbine,
Since the rotating brushes 11a and 11b can be driven to rotate,
A configuration having two rotating brushes can be realized at a light weight, a small size, and a low cost without forming a complicated structure only by forming the intake path and the guide as described above. Furthermore, this is also true when using an electric motor or a turbine.
Since the rotating brushes 11a and 11b are driven to rotate in the same direction, the configuration (in this case, the intake path and the guide) is relatively simple.

In the above embodiment, the intake path 27 is formed by providing the slit-shaped intake port 24 on the front surface of the lower case 3. The gap between the front bottom surface of 3 and the surface to be cleaned may be wider than the others, and the gap may be used as an intake path.
In this case, when a guide is formed at the front edge 7a of the suction port 7 to guide the outside air sucked from the gap to the brush body 15 and the blade 16 below the rotation center of each of the rotating brushes 11a and 11b. The brushes 11a and 11b can be driven to rotate efficiently.

An intake passage 23 having a guide opening 20 formed at the rear of the upper surface of the lid 4 is provided as an intake passage corresponding to the second rotating brush 11b.
The intake path 27 in which the first and second rotating brushes 11 and 11 are driven in the same direction by only the first rotating brush 11a and the second rotating brush 11b. It is possible to do.

FIGS. 6 to 10 show another embodiment, and each figure corresponds to FIGS. 1 to 5 of the above embodiment.
The same reference numerals indicate the same or corresponding parts.

In the above embodiment, the first rotating brush 11
The first and second rotating brushes 11a, 11b are formed on the front side of the lower case 3 with an intake path for mainly driving the rotation of the first rotating brush 11a.
Are rotated in the same direction. In the present embodiment, the second rotating brush 11b is not changed, but the intake passage for mainly rotating the first rotating brush 11a is covered with the lid 4. The first and second rotating brushes 11a and 11b are rotationally driven in opposite directions to each other.

That is, as shown in FIG. 6 and the like, a guide port 40 is formed on the front side of the upper surface of the lid 4 over substantially the entire width in the longitudinal direction of the brush body 15 and the blade 16 of the first rotary brush 11a. ing. On the front side of the guide port 40, a first rib 41a is formed which guides outside air sucked from the guide port 40 to the brush body 15 and the blade 16 of the first rotating brush 11a. The first rib 41a is extended almost up to the center of rotation of the first rotating brush 11a, and its tip is bent obliquely downward. The extending direction is the brush body 15 of the first rotating brush 11a, It is formed so as to be inside the rotation path of the blade 16 and to be tangential to the rotation path of the brush body 15 and the blade 16 of the second rotating brush 11b.

Also, a second rib 41b is formed on the rear side of the guide port 40 to form a guide for guiding outside air sucked from the guide port 40 to the brush body 15 and the blade 16 of the first rotary brush 11a. ing. This second rib 41b
Extends from the back surface side of the lid 4 to a position not in contact with the rotation trajectory of the brush body 15 and the blade 16 of the first rotating brush 11a toward the tangential direction of the brush body 15 and the blade 16, and the extension direction is the second direction. Brush body 15 of the rotating brush 11b
It is formed so as to be located inside the rotation locus of the blade 16. A discharge port 42 is formed between the distal ends of the first rib 41a and the second rib 41b.

The above-described guide port 40, the first rib 41a and the second rib 41b form an intake path 43, and the intake path 43 is configured so as to become narrower from the guide port 40 toward the discharge port 42. I have.
