Abstract

PROBLEM TO BE SOLVED: To surely eliminate static electricity generated in the floor surface to be cleaned or in the vicinity of a suction opening to facilitate removal of dust, and prevent dust from adhering to a sucker by replaceably installing an antistatic material in a bottom wall positioned in front and in rear of the suction opening in the base of the sucker body. SOLUTION: A suction opening 3 is opened in a bottom wall 1a of a sucker body 1, similarly a connecting port 4 is opened in the central part of the side wall 1b, and an inverted U-shaped pipe 5 is connected to the connecting port 4. An antistatic material 2 is installed in the bottom wall 1a positioned in front and in rear of the suction opening 3, whereby in using the sucker body 1, the antistatic material 2 is brought into contact with the floor surface of a carpet, a straw mat, or the like to eliminate static electricity. At this time, the antistatic material 2 may be directly planted in the bottom wall 1a, or a long body 6 planted with the antistatic material 2 may be removably installed in a fitting groove 7 formed in the bottom wall 1a. Thus, static electricity can be surely eliminated so as to facilitate removal of dust.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for a vacuum cleaner having a function of removing static electricity generated when the vacuum cleaner is used.

[0002]

2. Description of the Related Art When a vacuum cleaner is used, dirt and dust are sucked into the cleaner body together with air via a suction tool, an extension pipe, and a flexible pipe. However, at this time, the sucked dirt and dust collide with the inner wall surface of the inverted pipe communicating with the suction port of the suction tool, and generate noise due to the flow of air.

[0003] Therefore, in the conventional suction device for a vacuum cleaner, electrostatic flocking is applied to the inner wall surface of the inverted pipe, or an extension provided between the suction device and the main body of the vacuum cleaner. Electrostatic flocking on the inner wall surface of the pipe, and absorbing the energy that dust and dust collide with the inner wall surface of the inverted pipe and the wind noise caused by the flow of air,
The generation of noise was prevented.

[0004]

However, when a vacuum cleaner is used, static electricity is generated due to friction between the floor of a carpet or a tatami mat and the bottom surface of the suction tool, and this static electricity is applied to a carpet or a tatami mat. Electricity is charged on the floor and near the suction port of the suction tool, making it difficult to remove the dirt and dust accumulated on the floor, and fine dust and dust adhere to the entire outer wall of the suction tool, and the suction The tool itself becomes dirty, and during cleaning, the dirt on this suction tool comes into contact with clothes and other objects and adheres.
These also had the problem of becoming dirty. However, such a problem could not be dealt with by the above-mentioned conventional suction tool at all, and an urgent solution was awaited.

Accordingly, the present invention solves the above-mentioned conventional problems, and eliminates static electricity generated on the floor surface of a carpet or a tatami mat or the vicinity of a suction port of a suction tool, and removes dust and dirt accumulated on these floor surfaces. It is an object of the present invention to provide a suction device for a vacuum cleaner that facilitates removal of dust and the like and prevents fine dust and dust from adhering to an outer wall of the suction device.

[0006]

Therefore, the suction device for a vacuum cleaner according to the present invention has an antistatic member 2 attached to the bottom of a suction device body 1.

In the suction device for a vacuum cleaner according to the present invention, the antistatic material 2 can be attached to the bottom wall 1a at a position before and after the suction port 3.

Further, in the suction tool for a vacuum cleaner according to the present invention, the antistatic material 2 can be replaced freely.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a suction tool for a vacuum cleaner according to the present invention will be described in detail with reference to the drawings.

In the suction device for a vacuum cleaner according to the present invention, the suction device main body 1 is formed in a flat box shape as shown in FIGS. 1 to 7, and a pipe type as shown in FIGS. In any case, the antistatic member 2 is attached to the bottom of each of them.

In the embodiment shown in FIGS.
The suction port 3 is provided on the bottom wall 1a of the first embodiment, and a connection port 4 is provided substantially at the center of the side wall 1b. The antistatic material 2 is attached to the bottom wall 1a at the front and rear positions of the suction port 3. When the antistatic material 2 is mounted in this manner, the antistatic material 2 comes into contact with the floor surface of a carpet, a tatami mat, or the like when the suction tool is used, so that static electricity is eliminated by the antistatic material 2.

1 and 2, the antistatic material 2 is directly implanted on the bottom wall 1a of the suction tool main body 1, and in FIG. The long body 6 is implanted in a long body 6 made of a synthetic resin or the like, and the long body 6 is detachably fitted in a fitting groove 7 formed in a bottom wall 1a of the suction tool body 1. In the example shown in FIG.
The antistatic material 2 is attached to the bottom wall 1a of the suction tool body 1 so as to be replaceable by the adhesive layer 8. Further, in the apparatus shown in FIG.
In FIG. 6, the antistatic material 2 is directly planted on one screw blade 9 disposed inside the suction tool main body 1. I have. Further, in the one shown in FIG. 7, the antistatic material 2 is directly implanted on two rolls 10 arranged in parallel inside the suction tool main body 1. In addition, in what is shown in FIGS.
Although the screw blade 9 and the roll 10 are planted on the whole, they may be planted partially.

8 and 9, the antistatic material 2 is directly implanted in the bottom of the suction tool main body 1 at a position facing the elongated slanted opening 11 or around the round opening 12. As shown in FIG. And
10 and 11, the antistatic material 2 is provided with an adhesive layer 8, and the adhesive layer 8 allows the antistatic material 2 to be removably attached to the opposite portion of the inclined opening 11 or around the round opening 12. I have. If the antistatic material 2 is made replaceable in this way, it can be replaced with a new one if the antistatic effect of the antistatic material 2 is reduced.

As shown in FIG. 12, the antistatic material 2 is made of a conductive metal fiber (for example, copper, nickel, stainless steel or the like) or a metal-deposited fiber formed by vapor-depositing a metal such as copper, or a monovalent fiber. The fiber bundle 13 is made of a fiber or a carbon composite fiber formed by reducing and precipitating metallic copper in a chemical fiber in which copper ions are adsorbed. It has a belt shape. Further, although not shown, the antistatic material 2 made of the carbon composite fiber or the like can be configured as a knit, a woven fabric, a nonwoven fabric, or the like, in addition to the above-mentioned band shape, a string shape, a twisted yarn shape, or the like. .

The suction device for a vacuum cleaner according to the present invention having the above-described structure is used in the same manner as a suction device for a normal vacuum cleaner, and the antistatic material 2 is placed near or on a floor such as a carpet or a tatami mat. If the antistatic material 2 is brought into contact, corona discharge is effectively generated between the antistatic material 2 and a floor surface of a carpet, a tatami mat or the like, so that charging can be neutralized smoothly. In the vicinity, the state where static electricity is eliminated can be maintained.

[0016]

Since the suction device for a vacuum cleaner according to the present invention is constructed as described above, static electricity generated on the floor surface of a carpet or a tatami mat or near the suction port of the suction device is eliminated. It is easy to remove dust and dirt accumulated on these floors, and fine dust and dirt do not adhere to the outer wall of the suction tool, so that the suction tool itself does not become dirty and during cleaning. Dirt on the suction device does not adhere to clothes or other objects and becomes dirty.
