It was as shown in FIG. 4 and FIG. That is, the suction tool main body 1 is formed by the upper case 2 and the lower case 3,
A suction port 4 is formed in the lower case 3, and small front rollers 5 and rear rollers 6 are provided at the front and rear, respectively, for running the suction tool body 1. Further, the gap A between the lower surface 7 around the suction port 4 of the lower case 3 and the floor surface increases the adsorbing force on the floor surface and increases the flow velocity of the airflow flowing through the gap A portion to strongly remove dust. In order to inhale, the gap cannot be made large, conversely if it is too small, there is a problem that hard dust etc. gets caught in this gap and damages the floor surface,
The size was set to be about 0.5 to 2 mm. For this reason, in order to further increase the suction force, a lip-shaped band 8 made of a soft material is provided immediately behind the suction port 4 so as to be closer to the width of the suction tool main body 1.

[0003]

However, in such a construction, the front roller 5 and the rear roller 6 are buried in the carpet by the suction force, especially on a carpet on which a suction force is applied to the suction tool main body 1. As a result, the lower surface portion 7 of the lower case 3 is pressed against the carpet. At the same time, the lip-shaped band 8 is similarly pressed onto the carpet. As a result, the frictional resistance between the entire lower surface 7 of the lower case 3 and the carpet is increased, and the operational resistance of the suction tool main body 1 is extremely heavy, resulting in a state of inconvenience.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a vacuum cleaner which is excellent in usability without increasing frictional resistance even when used on a carpet. .

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to 2 and 3. The suction tool main body 11 includes an upper case 12 and a lower case 13, and forms a suction port 15 in a lower surface 14 of the lower case 13, and a pair of left and right front portions of the lower case 13 for traveling. A roller 16 is provided, and a rotating roller body 17 is provided at the rear.

The rotary roller body 17 has a configuration as shown in FIG. That is, a raised cloth 19 formed of a cut pile-shaped spun cloth formed of fine fibers is spirally wound around the outside of the pipe 18.
The fine fibers 9 are inclined and wound in the radial direction with respect to the pipe 18. Holders 20 are fixed to both end surfaces of the pipe 18. A bearing 23 is rotatably fitted to a shaft fixed to the holder 20. A coil spring is mounted between the holder 20 and the bearing 23 in a compressed state. The bearing 23 can move toward the holder 20 in the direction of further compressing the coil spring,
It is also arranged so that it can be returned to the original position by the elastic force of the coil spring. The bearing 23 is fitted in a bearing hole 26 formed in the lower case 13, and when the bearing 23 is moved in the thrust direction by holding the raised cloth 19 of the rotating roller body 17, one of the directions is a direction in which the coil spring is compressed. The bearing 23 is removed from the bearing hole 26 by the movement of the other, and the rotating roller body 17 can be removed from the lower case 13. Further, when the bearing 23 is inserted, it can be easily inserted by pressing the bearing 23 to the thrust side to contract it.

According to the present invention, the suction device main body 11 having the above structure is provided.
When a suction force is applied to the carpet, the wide rotating roller body 17 is provided at the rear portion of the lower case 13, so that the pressure receiving area is large, and the rotating roller body 17 is hardly buried in the carpet due to the suction force. Therefore, the lower surface portion 14 of the lower case 13 is not pressed against the carpet. In addition, the rotating roller body 1 receiving pressure
7 rotates with the movement of the suction tool body 11, the frictional resistance between the entire lower surface 14 of the lower case 13 and the carpet does not increase, and the operation resistance of the suction tool body 11 changes little even when suction force is applied. Nothing to do. The rotating roller body 17 is formed by winding a raised cloth 19 formed of a cut pile-shaped spun cloth formed of fine fibers around a pipe 18, and the fine fibers of the raised cloth 19 are applied to the pipe 18. Since it is inclined and wound in the radial direction, that is, in the direction in which the suction tool main body is operated, even when cleaning the carpet, the frictional resistance received from the carpet weave can be reduced, so that smooth running can be obtained. Further, one holder 21 of the rotating roller body 17 and the bearing 2
By fixing 3 to the thrust direction, even if it receives frictional resistance from the carpet, it can be prevented from moving to one side, so that a smooth running property can be obtained.

In addition, even if hair is entangled with the surface of the cut pile spun cloth formed of fine fibers, the rotating roller body 17 is detachably provided on the lower surface 14 of the lower case 13 so that it can be removed. And easy to care for. Also,
The raised cloth 19 has a configuration as shown in FIG. Arrow A2 in which fine fibers are inclined in the radial direction after the sheet 27 cut to the processing size is wound around the pipe 18.
After inclining in eight directions, by cutting at an angle A29 with respect to this incline, the napping cloth 19 is wound around the pipe 18. Can be done

[0011]

According to the present invention, with the above construction, a wide rotating roller body is provided on the carpet, so that the pressure receiving area is large, and the rotating roller body is hard to be buried in the carpet due to the attraction force. Since the rotating roller body rotates as the suction tool body travels, the frictional resistance between the entire lower surface of the lower case and the carpet does not increase, and the operation resistance of the suction tool body changes little even if suction force is applied Nothing to do.

Also, since the fibers of the raising cloth are inclined and wound in the radial direction of the rotating roller body, that is, in the direction of operating the suction tool main body, the direction of the weave of the carpet is also required when cleaning the carpet. As a result, the frictional resistance can be reduced, so that a smooth running performance can be obtained.
