Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for floors, wall surfaces, glass surfaces and the like (including those having a polishing function and a polishing function).

[0002]

2. Description of the Related Art Conventionally, in a rotary brush device of this type of washing machine, a brush mounting base is made of a plywood, hard plastic or other non-foldable hard material. When this hard brush mount hits a wall or furniture, it often causes scratches on the wall or furniture, which causes cleaning scratches on corners and narrow areas. Is more difficult to work because it requires more nerve, and for example, if there is a convex portion on the floor or wall that exceeds the cushioning (flexibility) of the brush body, There is a fear that it will build up, so it is difficult to use because it can not be jumped over, and the cushioning property (flexibility) is not always sufficient, and in the degree of familiarity with the cleaning surface such as the floor surface, especially in a place where the cleaning surface is curved. There is a defect that the center part of the brush body floats from the same curved surface, and in the place where the curved surface is convex, the peripheral part floats from the convex curved surface and the cleaning action only half functions. It was.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a novel washing machine which is devised to eliminate the above-mentioned defects of the rotary brush device in the washing machine in which the brush mount is made of a hard material such as plywood. An object is to provide a rotating brush device.

[0004]

In order to achieve the above object, a rotary brush device in a washing machine according to the present invention has a brush main body on the lower surface of a brush mounting base 3 having a mounting portion 2 for a rotary drive shaft 1 at the center. In the rotary brush device in the washing machine of the type in which 4 is provided, the brush mounting base 3 is made of an elastic material such as elastic soft synthetic resin, metal or rubber and has a conical shape.

[0005]

In the embodiment shown in FIGS. 1 and 2, a boss member 7 having a bayonet receiving portion 6 on its outer peripheral edge is fixed to a rotary drive shaft 1 in a detachable and non-rotatable manner by screwing. A detachable member 10 having a bayonet insertion portion 8 at the upper edge of the inner circumference and a flange 9 at the lower edge of the outer circumference is separately configured, and separately from these, a soft synthetic material having elasticity (stretchability). A conical brush mounting base 3 is made of resin, a mounting hole 11 is formed at the apex of the brush mounting base 3, and the attaching / detaching member 10 is fitted into the mounting hole 11 from below to form the central hole. The cutting edge is placed on the flange 9, and the cutting edge is clamped between the large diameter nut 12 and the flange 9 by tightening the large diameter nut 12, and the entire lower surface of the brush mounting base 3 is fixed. On the male side of the velvet fastener 13 is non-detachably attached, and the felt brush 14 is lightly pressed against the male member 13 to hold the felt brush 14 on the brush mount 3 in a replaceable manner, and the detachable member 10 to the boss member 7. It is fitted and attached to the rotary drive shaft 1.

The present invention uses a circular pad made of pile cloth made of, for example, thick thread, a sponge brush, or a brush in which abrasive particles are sprinkled with abrasive particles other than the felt brush 14 as the brush body 4. To do this, directly implant long bristles made of synthetic resin monofilament on the lower surface of the brush mount 3, and use a cone-shaped elastic member with a cut 18 as the brush mount 3 as shown in FIGS. 3 and 4. A material or an elastic member may be inserted to obtain an elastic force.

[0007]

In the present invention, the brush mounting base 3 made of an elastic soft synthetic resin is adapted to obtain a surface pressure (pressing force) against a cleaning surface such as a floor surface due to its own elasticity. 2 and a curve 16 shown in FIG. 2 (such as the ceiling of a train) or a curve 16 in FIG.
When the brush mounting base 3 and the brush main body 4 are bent along a curved surface, the brush mounting base 3 and the brush main body 4 have elasticity and centrifugal force which the brush mounting base 3 itself has. With the force of trying to become horizontal, the curved surface is strongly pressed in a contact state with the entire surface (wide area surface).

[0008]

The rotary brush device in the cleaning machine according to the present invention is a rotary brush in a cleaning machine of the type in which the brush main body 4 is provided on the lower surface of the brush mount 3 having the mounting portion 2 for the rotary drive shaft 1 in the center. In the apparatus, since the brush mount 3 is made of a soft synthetic resin having elasticity and has a conical shape, even if the brush mount 3 hits a wall or a furniture during use. As long as it does not hit extremely strongly, it will not scratch the walls or furniture, and when cleaning corners and narrow areas, you can easily and speedily work without the need for nerves. ,
In addition, the elasticity of the brush mount 3 itself and the cushioning property (flexibility / flexibility) of the brush body greatly exceed the limit of the cushioning property of the brush body in the conventional example described above.
The possibility of creating scratches is almost eliminated, and even a slightly high convex part can be used by easily jumping over without scratching, and in such usage, a relatively large recess on the cleaning surface such as the floor surface. However, since the tip of the brush body enters deeply for cleaning, and the cushioning property is extremely high as described above, it is not only suitable for cleaning glass windows that are easily damaged, but also as described in the above operation. In addition, the brush main body 4 strongly presses against the curved surface when cleaning a curved surface such as a ceiling of a train, and strongly presses against the curved surface when cleaning a convex curved surface in a state of full contact. Therefore, it has excellent effects such as being extremely preferable in cleaning work.
