Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bedding suction tool that is used by being connected to the tip of a vacuum cleaner.

BACKGROUND ART Conventionally, this type of suction device used for bedding such as futons and blankets has been constructed as shown in FIG.

That is, the connecting pipe 2 is rotatably attached to the suction tool main body 1, and the rotary cylinder 3 is rotatably held on the floor side of the suction tool main body 1 approximately at the center in the front-rear direction to its full width. Ta.

However, in such a suction tool, the rotary cylinder 3
The protrusions formed around the bedding cover became entangled with the net portion of the bedding cover, making it extremely difficult to use.

As a solution to this problem,
There was a suction tool shown in Publication No. 5606.

In this suction tool, a rotating body was provided on the bottom surface of the suction tool body, and the rotating body was driven to rotate by an electric motor. The rotating body was configured by having a plurality of eccentric cylindrical rollers arranged in series in the longitudinal direction with a phase shift in the circumferential direction.

Problems to be Solved by the Invention In the suction device shown in the above-mentioned conventional example, the cylindrical roller constitutes a large number of unevenness when viewed in the longitudinal direction of the rotating body, and it certainly has the effect of deforming the surface of the bedding into an uneven shape. has. However, this is completely different from the so-called futon beating action.

In other words, the height change of the eccentric cylindrical roller relative to the bedding surface takes the form of a continuous connection as part of a circle, and accordingly, the bedding surface also deforms continuously while being in contact with this circle. As a result, there was almost no effect of hitting the surface of the bedding.

Therefore, even when this suction device is used for bedding, although it sucks up the dust on the surface, it cannot be expected to have much of an effect in sucking out the dust inside.

Additionally, in general, if a rotating body is forcibly rotated by an electric motor or the like, there is a risk that a bedding cover or the like may get wrapped around the rotating body and be torn, so a rotating type in which the rotating body freely rolls is more suitable for bedding. but,
When a rotating body that combines the above-mentioned cylindrical rollers is used as an autorotating rotating body, it has a circular shape, so
The friction against the surface of the bedding was small, so it slipped and could not be rotated properly.

The present invention solves the above conventional problems,
Even if it is a rotating body, it rolls well on the bedding,
It is an object of the present invention to provide a suction tool for bedding which is excellent in usability and functionality and can satisfactorily tap the surface of bedding.

Means for Solving the Problems The technical means of the present invention to achieve the above object is to have a connecting pipe connected to the vacuum cleaner body on one side, and a suction port communicating with the connecting pipe on the bottom surface. The suction device has a formed suction tool main body, and a plurality of rotors that are arranged at the bottom of the suction tool main body and rotate in contact with the surface of the bedding, and the rotors have a predetermined width in the longitudinal direction and have a width on three sides. The apexes of the extending protrusions are arranged in a substantially equilateral triangular shape, and a plurality of strikers are arranged in a row with the circumferential phase shifted in the longitudinal direction, and the peripheral wall between these protrusions is located inside the line connecting the apexes. It is composed of

Function In the above configuration, since the rotor striker has the apexes of protrusions extending in three directions arranged in a substantially equilateral triangular shape, the vertical displacement stroke of the protrusions relative to the bedding surface is large, and the vertical displacement between adjacent protrusions is large. Since the displacement stroke is also large, the surface of the bedding is beaten in a complicated manner in a so-called checkerboard pattern.

Furthermore, even if the striking element itself is triangular in shape, when looking at the protrusions of adjacent striking elements as a whole, it takes on a hexagonal shape. Rotate to.

Embodiment Hereinafter, the embodiment will be described based on the drawings.
In FIGS. 1 to 5, the suction tool main body 11 includes an upper suction tool 13 rotatably holding a connecting pipe 12 for connecting to an extension pipe of a vacuum cleaner, and an upper suction tool 13 that is attached to the upper suction tool 13 from below. The lower suction tool 14 is attached to the lower suction tool 14 and is located approximately at the center in the front-rear direction, and has a suction port 15 formed over the entire width of the left and right sides.

The suction port 1 in the lower suction tool 14
A pair of self-rotating rotors 16 located at the front and back of the
is located.

The suction port 15 is approximately 10 mm from the lower end of the rotor 16.
mm, and its front and rear width is approximately 6 mm.
It is set to be mm.

The rotor 16 has a hollow shape, has a predetermined width in the longitudinal direction, and has a striking element 17 in which the apexes of protrusions extending in three directions are arranged in a substantially equilateral triangular shape. It is made up of multiple installations arranged 180 degrees apart. Specifically, the width of the striking element 17 is set to about 20 mm. Further, one side of each striker 17 is formed in a planar shape, and the other two sides are formed in a concave shape, and furthermore, the lowest end of the circular locus drawn by the apex of the projection protrudes from the lower end of the suction port 15 by about 5 mm. Both ends of the rotor 16 are supported by a rotating shaft 18 that is integrally formed with the lower suction tool 14 .

The effects of the above configuration will be described.

When the suction tool 11 is connected to a vacuum cleaner and moved in the front-rear direction over bedding, etc., the rotor 16 rotates on its own axis while the protrusion of the striker 17, which has a substantially equilateral triangular cross section, contacts the surface of the bedding. The surface of the bedding is then rhythmically tapped to knock out the dust and sucked into the vacuum cleaner through the suction port 15.

Furthermore, the operation of the rotor 16 will be explained in detail.

Since the striker 17 of the rotor 16 has the apexes of protrusions extending in three directions arranged in a substantially equilateral triangular shape, the vertical displacement stroke H of the protrusions relative to the bedding surface is large as shown in FIG. Since the vertical displacement stroke between the protrusions is also large, the surface of the bedding is beaten in a complicated manner in a so-called checkerboard pattern.

Further, even though the striking elements 17 themselves have a triangular shape, when the protrusions of the adjacent striking elements 17 are viewed as a whole, they have a hexagonal shape. It also rotates well.

In general, in a stepped polygonal rotor, the smaller the number of angles, the greater the beating effect, and conversely, the larger the number of angles, the smoother the rotation. In other words, those on a flat plate with a rod-shaped cross section and beaters at both ends are superior in terms of the futon-beating effect;
The rotatability is extremely poor; conversely, those with square or more angles have excellent rotatability but are inferior in the futon-beating effect.

In this embodiment, by alternately arranging the striking elements 17 each having a substantially equilateral triangular cross section with a phase shift in the circumferential direction, it is possible to achieve both a futon beating effect and good rotational performance.

Furthermore, since the blower 17 is intermittently in contact with the surface of the bedding, the air flowing into the suction port 15 also repeats the strength and weakness of some parts. Therefore,
The dust thrown out onto the bedding surface is reliably sucked through the suction port 15.

The rotor 16 can be molded using two-part molds A and B as shown in FIG.

In the above embodiment, the shape of the striker 17 is approximately an equilateral triangle, and two of the three sides are concave to emphasize the protrusions. As long as it is located inside the connecting line, it is not limited to the configuration of the above embodiment, and can be selected as appropriate.

Effects of the Invention As described above, the present invention provides a suction tool body that has a connecting pipe connected to the vacuum cleaner main body on one side and a suction port that communicates with the connecting pipe on the bottom surface, and the suction tool main body. It is equipped with a plurality of rotors arranged at the bottom of the bed and rotates in contact with the bedding surface,
The rotor is a striker having a predetermined width in the longitudinal direction and having the apexes of protrusions extending in three directions arranged in a substantially equilateral triangle shape, and the peripheral wall between these protrusions being located inside a line connecting the apexes. A plurality of suction devices are arranged in series with their circumferential phases shifted in the longitudinal direction of the same rotor, and the suction device for bedding has excellent effects as described below.

Since the rotor's striker has the apexes of protrusions extending in three directions arranged in a substantially equilateral triangular shape, the vertical displacement stroke of the protrusions relative to the bedding surface is large, and the vertical displacement stroke between adjacent protrusions is also large. As a result, the surface of the bedding is beaten evenly in the front, back, left and right, in a complicated and reliable manner in a so-called checkerboard pattern.

Therefore, dust is reliably knocked out and bedding can be cleaned well.

Even though the striker itself is triangular,
When viewed as a whole, the protrusions of adjacent striking elements have a hexagonal shape, which allows for good rotation even on the surface of bedding made of slippery fabric.

Therefore, smooth rotation can be obtained, and the dust removal characteristics can be further improved. Also, since it rotates smoothly, it does not cause damage to bedding, etc.

Since the blower of the rotor is intermittently in contact with the surface of the bedding, the air flowing into the suction port also repeats the strength and weakness of some parts.

Therefore, the dust thrown out onto the surface of the bedding is reliably sucked through the suction port, and as a result, the dust suction characteristics can be significantly improved.
