CONSTITUTION:This suction implement for the vacuum cleaner is constituted so that its operation can be executed lightly and softly even on a wooden floor and on Tatami mat (rush mat for Japanese style room), and also, on a carpet by providing a raising cloth 18 provided in front of a suction port 14 on the lower face of a suction implement main body 10 and a rotary raising cloth roller 30 provided in the rear of the suction port 14, and dust in the carpet can also be eliminated beautifully by dust eliminating brushes 22, 23 provided before and behind the suction port 14.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner suction tool.

[0002]

2. Description of the Related Art A conventional suction device of this type is disclosed in, for example, Japanese Patent Laid-Open No.
As shown in Japanese Patent No. 114714, the structure is as shown in FIG. 4, and a bank-shaped mounting seat 3 is formed on the outer periphery of a lower suction tool 2 having a suction port 1 for sucking dust and the like, The seat 3 has a raised cloth 4 made of a cut pile spun cloth.
Was provided.

[0003]

However, with such a structure, when cleaning the wooden floor and the tatami mat, the cleaning surface and the lower suction tool are brought into contact with each other by the cleaning surface coming into contact with the raised cloth 4. Although it is possible to prevent scratches due to friction with 2, and to obtain a soft feeling during cleaning work, when cleaning the carpet, the rug and the raised cloth 4 rub strongly, resulting in heavy operability. Moreover, there is a problem that the raised cloth 4 cannot be removed by rubbing dust on the carpet.

An object of the present invention is to solve this problem and to provide an excellent suction tool which can be lightly operated even when cleaning the carpet, and which can well remove dust and the like.

[0005]

[Means for Solving the Problems] A first means of the present invention in order to solve such a conventional problem is a suction tool body having a suction port, and a cut pile spinning provided in front of the suction port. It is composed of a napped cloth made of cloth, a dust removing brush provided before and after the suction port, and a rotary napped roller provided behind the suction port.

[0006]

In the above-mentioned means of the present invention, a raised cloth is provided in front of the suction port, and a rotary raised cloth roller is provided behind the suction port where the force is most applied when pushing the suction tool. Since the rotating brushed cloth roller rotates, scratches due to friction between the cleaning surface and the suction tool can be prevented, a soft feeling during cleaning work can be obtained, and cleaning work can be performed with a light operating force. By providing the dust removing brushes before and after the suction port, dust and the like adhering to the cleaning surface can be reliably removed by rubbing against the dust removing brush when cleaning the carpet.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment will be described below with reference to the accompanying drawings. 1 to 3, reference numeral 10 denotes a suction tool body, which is obtained by connecting an upper suction tool 12 and a lower suction tool 13 via a bumper 11, and has a lower opening inside the front and a suction opening 14. A suction chamber 15 is formed. The center of the suction chamber 15 is at the rear of the suction tool body 10 and the upper suction tool 1 is provided.
2. Communication pipe 16 sandwiched between lower suction tool 13 so that it can be lifted up and down
An extension pipe, which is connected to the suction side of the electric vacuum cleaner via a hose, is detachably connected to the connection pipe 17 rotatably connected to the communication pipe 16. Reference numeral 18 denotes a raised cloth made of a cut pile spun cloth, which is fixed to the mounting seat 19 by adhesion. This mounting seat 19 is the lower suction tool 13
It is removably fixed by the concave groove 20 and the locking claw 21 provided in the. Numerals 22 and 23 are dust removing brushes, which are adhered and fixed to mounting seats 24 and 25, respectively. It is detachably fixed by. The dust removing brush 22 is attached in a direction to remove dust on the cleaning surface when the suction tool body 10 is moved forward, and the dust removing brush 23 is
The suction tool body 10 is mounted so as to remove dust on the cleaning surface when the suction tool body 10 is moved rearward. Reference numeral 30 denotes a rotary raised cloth roller, which is composed of a substantially cylindrical rotor 31 and a raised cloth 32 made of a cut pile spun cloth adhered and fixed to the outer peripheral surface of the rotor 31. Is press-fitted and fixed, and the shaft 34 is press-fitted and fixed to the shaft support 33. A bearing 35 is supported on the shaft 34 so as to be movable in the thrust direction.
A spring 36 is arranged between the shaft support 33 and the bearing 35.
The bearing 35 and the bearing 35 are always urged away from each other. The shaft support 33 is provided with a retaining claw 37 for the bearing 35 to prevent the bearing 35 from coming off the shaft 34. By inserting the bearing 35 into the mounting hole 38 provided in the lower suction tool 13, the rotary raised cloth roller 30 can freely rotate with respect to the suction tool body 10, and the bearing 3
By moving 5 in the thrust direction, the mounting hole 38
Further, the rotary raised cloth roller 30 can be detached from the suction tool main body 10.

The operation and action of this embodiment will be described below. When cleaning the wooden floor and the tatami mat with the suction tool body 10, the cleaning surface and the raised cloth 32 on the rotating raising cloth roller 30 are in contact with each other, so that the cleaning surface and the lower suction tool 13 are It is possible to prevent scratches due to friction and to obtain a soft feeling during cleaning work. Further, when cleaning the carpet with the suction tool body 10, the rotary raised fabric roller 30 supports the load applied when pushing the suction tool body 10 to assist the movement of the suction tool body 10 by rotating. Therefore, the cleaning work can be performed with a light operation force. When cleaning the rug, the dust on the rug adheres to the dust removing brush 22 when the main body 10 of the suction tool is pushed, and the dust on the dust removing brush 23 is separated due to friction with the rug. When the suction tool body 10 is pulled further, dust on the carpet adheres to the dust removing brush 23, and the dust on the dust removing brush 22 is separated by friction with the carpet and is sucked from the suction port 14. By repeating the above steps, cleaning work can be performed neatly on the carpet.

[0009]

As is apparent from the above embodiments, according to the present invention, when cleaning a wooden floor or tatami mat,
Due to the effect of the nap cloth, it is possible to prevent scratches and give a soft feeling in operation.When cleaning the carpet, the effect of the nap cloth roller allows a light operation force, and the effect of the dust removal brush. Since dust on the rug can be reliably removed and the above operation can be used without switching the cleaning surface, it is possible to provide a suction tool for an electric vacuum cleaner that has good operability, durability, and usability.
