Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction body of an electric vacuum cleaner having a rotary brush which is a rotary body for scraping dust, and more particularly to a rotary brush having a function of wiping a wooden floor or the like.

[0002]

2. Description of the Related Art The suction body of the conventional vacuum cleaner is
-11246, as described in the rotating force of the rotating brush,
The suction force from the main body of the cleaner sucks dust.

[0003]

However, due to recent changes in housing conditions, the number of wooden floors is increasing, and along with this, there is an increasing demand for a wooden floor wiping function.

An object of the present invention is to provide a suction body of an electric vacuum cleaner capable of cleaning and wiping a wooden floor, which was not possible in the conventional example.

[0005]

The above object is to provide a rotating body having bearings at both ends and rotating in the forward and reverse directions, and drive means for driving the rotating body, wherein the rotating body has a carpet or the like on its outer periphery. This can be achieved by a suction part in which a rotating brush has a blade portion that knocks out the dust and a brush portion that is upright on the surface of the blade portion and is bristled for wiping.

[0006]

The present invention is a mouthpiece having a rotating brush composed of a blade portion for knocking out dust such as a carpet and the like on the outer periphery and a brush portion for upsetting the bristles upright on the surface of the blade portion as a rotating brush. In the case of cleaning such as the above, if the blade portion is rotated so as to come into contact with the cleaning surface, dust hidden in the back of the carpet is knocked out by the blade portion. When cleaning a wooden floor, etc., if you rotate the brush part so that it contacts the floor surface, the brush will be wiped while standing upright on the floor surface, so you will be able to clean efficiently without leaving unpolished parts. Is.

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

The suction body 1 has an outer casing formed by the upper case 2, the lower case 3 and the suction port cover 4, and a bumper for preventing damage to furniture and the like between the lower case 3 and the upper case 2 and the suction port cover 4. 5, a casing 6 which is rotatable up and down is provided at the rear end portion, and a rotatable suction joint 7 is connected to the tip thereof. A horizontally long suction port 8 is located below the front side of the lower case 3.
A pressure control plate 9 that has flexibility and is provided in front of and behind the suction port 8 and holds the suction pressure in the suction port 8 in the lateral direction. In addition, the lower case 3 has the roller 10 on the lower front side.
A wheel 11 is provided on the lower rear side, and the roller 10 and the wheel 11 cause a constant gap between the lower surface of the lower case 3 and the floor surface. Inside the suction body 1, there are a rotary brush chamber 13 that houses the rotary brush 12, and a motor 14 that serves as a driving means for the rotary brush 12. Rotating brush 1
2 is provided with a plurality of groove portions 16 continuous in the longitudinal direction of the rotary core portion 15, and the rotary brush 12 having a blade portion 17 and a brush portion 18 is fitted at two target portions in the cross section of the groove portion 16, Rotational imbalance is not generated in the cross section. In the rotary brush 12, a brush portion 18 in which a brush 19 made of pile fibers is planted on a base cloth 20 is erected on either surface of a plate-like blade portion 17 made of an elastic material such as rubber. Since they are fixed and configured to have a substantially T-shaped cross-section including the base portion 21 and are fitted into the groove portions 16, respectively, they do not fall off due to the rotational force of the rotary brush 12. On the other hand, for rotation of the motor 14, the drive shaft 23 is arranged at a position facing the driven shaft 22, and the belt 2 is rotated.
4 is transmitted to the rotating brush 12. Here, in FIG. 8, a hose 25 and an extension tube 2 are attached to a cleaner body (not shown).
6, the state where the mouthpiece 1 is connected is shown, and the hose 25
Is provided with a bent joint 27 at the extension pipe side connection portion.
The bending joint 27 is provided with a switch button 28 for performing forward / reverse rotation of the motor 14.

In the suction body 1 constructed as described above, the motor 14 rotates in accordance with the switch button 28, and the rotary brush 12 rotates in the same direction as the motor 14. Since the brush portion 18 of the rotating brush 12 is fixed to only one surface of the blade portion 17, the rotating direction of the rotating brush 12 is adjusted by the switch button 28 so that the blade portion 17 or the brush portion 18 contacts various cleaning surfaces. If is changed, the effects of dust slamming and wiping can be enhanced.

According to the present embodiment, the suction body 1 having a rotating brush in which the brush portion 18 made of pile fibers is vertically fixed to the surface of the plate-shaped blade portion 17 made of an elastic material such as rubber. Therefore, in the case of cleaning the carpet with one switch button 28, if the blade part is rotated so as to contact the cleaning surface, the dust hidden inside the carpet is knocked out, and the wooden floor or the folding surface is folded. When cleaning such as, if you rotate the brush so that it touches the floor surface or the surface of the fold,
Since the brush stands upright on the cleaning surface and then wipes, there is no leftover polishing, etc., and efficient cleaning is possible.

[0011]

According to the present invention, in the case of cleaning a carpet or the like, if the blade portion is rotated so as to come into contact with the cleaning surface, dust hidden in the back of the carpet is knocked out by the blade portion. , When cleaning a wooden floor or fold, if you rotate the brush so that it contacts the floor or the surface of the fold, you can wipe the brush while standing upright on the cleaning surface.
It is possible to provide a suction body of an electric vacuum cleaner that can be efficiently cleaned without leaving unpolished parts.

As described above, there is an effect that a carpet, a fold, and a wooden floor can be efficiently cleaned with one rotating brush.
