Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an electric vacuum cleaner,
In particular, the present invention relates to an electric vacuum cleaner capable of surely cleaning furniture and the like, where dust is easily noticeable.

[0002]

2. Description of the Related Art In recent years, with the spread of audio-video products, audio products, and the like, furniture with a black surface is increasing in the residential environment. When dust adheres to furniture having such a black surface, particularly furniture having a black and glossy surface, it is very noticeable.

In order to clean the surfaces of these furniture without damaging them, the electric vacuum cleaner main body is provided with, for example, an actual flat panel 1-104947.
As disclosed in Japanese Patent Publication (International Patent Classification A47L 9/02), a suction tool in which a brush is installed is connected via a hose.

[0004]

However, there are many users who feel that dust must be cleaned more reliably for these furnitures, which are particularly conspicuous with dust,
In addition, there are many users who are reluctant to clean their favorite high-end furniture, audio products, etc. with brushes that have been used to clean shoji screens, long presses, rails, crosspieces, etc.

Therefore, in order to clean these furnitures, a chemical rag, mop or the like having an electrostatic adsorption function is often used rather than an electric vacuum cleaner.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an electric vacuum cleaner capable of reliably cleaning furniture or the like where dust is easily noticeable.

[0007]

To achieve the above object, the present invention provides an electric vacuum cleaner having a vacuum cleaner main body and a suction tool connected to the vacuum cleaner main body via a hose or the like. The suction tool is a tubular connection part connected to the electric vacuum cleaner body via a hose, a suction part communicated with the connection part, and a brush implanted at the tip of the peripheral part of the suction part. , A cover body that covers the outer periphery of the suction part and is slidably fitted on the suction part, and a tip supported by the cover body, and the tip of the cover body is moved forward and backward so that its tip is ahead of the tip of the brush. And a dust collecting member that is moved in and out of
The dust collecting member is formed of a member having a dust collecting effect by electrostatic attraction.

[0008]

In the present invention, the dust collecting member having the dust collecting effect by electrostatic attraction can be moved forward and backward with respect to the tip of the brush of the suction portion by moving the cover body forward and backward. Therefore, by retracting the dust collecting member from the tip of the brush of the suction portion, the cleaning object can be cleaned with the brush of the suction portion in the same manner as in the conventional case, while the dust collecting member is removed from the tip of the brush of the suction portion. By advancing, the dust collecting member can surely attract and clean the dust on the body to be cleaned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings.

As shown in the perspective view of FIG. 1, an electric vacuum cleaner according to an embodiment of the present invention has a cleaner body 1, a bellows hose 2 connected to the cleaner body 1, and a bellows hose 2. The suction tool 3 is provided.

As shown in the sectional view of FIG. 2 and the side view of FIG. 3, the suction tool 3 has a cylindrical connecting portion 4 which is inserted into the bellows hose 2 and a suction portion 5 which is connected to and connected to the connecting portion 4. When,
The brush 6 is provided at the tip of the peripheral portion of the suction portion 5.

The suction tool 3 covers the outer periphery of the suction section 5 and is fitted onto the suction section 5 so as to be spirally slidable. The cover body 7 is supported by the cover body 7. A brush-shaped dust collecting member, that is, a brush outer member 8, is provided, the tip of which moves forward and backward with respect to the tip of the brush 6 when the brush 7 is moved back and forth.

The brush outer 8 is formed of a member such as polypropylene fiber having a dust collecting effect by electrostatic attraction.

Further, the suction part 5 is rotatably fitted to the connection part 4 about an axis intersecting with the axis of the connection part 4, and rotates the suction part 5 with respect to the connection part 4. As a result, for example, as shown in FIG. 1, the connection portion 4 is brought into a state of communicating with the suction portion 5 in a straight tubular shape, or, for example, as shown in FIG.
The direction of the suction portion 5 with respect to the axial center of the connection portion 4 can be changed so that the connection portion 4 communicates with the suction portion 5 in a bent tubular shape.

That is, the tip end surface 4a of the connecting portion 4 is tilted with respect to its axis, and a circular hole 4b is formed in the tip end surface 4a so that the base end surface 5a of the suction portion 5 becomes the tip end surface 4a of the connecting portion 4. The claw 5b is provided so as to be inclined corresponding to the above and is engaged with the edge of the circular hole 4b.

In this vacuum cleaner, for example, FIG.
As shown in (a), when the cover body 7 is advanced beyond the suction part 5 and the tip of the brush outer 8 is advanced beyond the tip of the brush 6, the brush outer 8 having a dust collecting function by electrostatic attraction. The cleaning can be performed by, for example, it is possible to surely adsorb and clean the dust from the surface of furniture such as audio / video products, obdio products, and high-end furniture where the surface of the furniture is easily noticeable.

Further, for example, as shown in FIG. 2B, when the cover body 7 is retracted to the base end side of the suction portion 5 and the tip of the brush outer 8 is retracted from the tip of the brush 6, the same as in the conventional case. The brush 6 can be used for cleaning, and for example, shoji, long press, railing, crosspieces, etc. can be cleaned.

That is, the brush 6 and the brush outer 8 having a dust collecting function by electrostatic attraction can be selectively used according to the degree of dust conspicuousness, and the brush outer having a dust collecting function by electrostatic attraction is used. 8
By using, it is possible to extend the cleaning target products to high-quality furniture, audio products, etc. where dust is particularly noticeable.

Further, in this embodiment, since the suction portion 5 is rotatably fitted to the connection portion 4 about an axis intersecting the axis of the connection portion 4, the direction of the suction portion 5 is changed. By changing the shape, the shape of the suction tool 3 can be changed to a shape suitable for long pressing and cleaning of the top of a shelf, etc., and usability can be improved.

[0020]

As described above, according to the present invention,
A brush similar to the conventional one and a dust collecting member having a dust collecting function by electrostatic attraction can be selectively used according to the degree of dust conspicuousness, and dust is particularly conspicuous by cleaning using the dust collecting member. Items to be cleaned can be expanded to high-end furniture and audio products.

In the present invention, especially when the suction part is rotatably connected to the connection part about an axis intersecting with the axis of the connection part, the direction of the suction part with respect to the connection part is changed. Since the shape of the suction tool can be changed to a shape suitable for cleaning on a shelf or on a long press, usability can be improved.
