Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction nozzle for a vacuum cleaner, which has a rotary rotor driven and rotated by a driving device as an attachment of the vacuum cleaner.

[0002]

2. Description of the Related Art A conventional rotary rotor of a suction nozzle (hereinafter referred to as a nozzle) for a vacuum cleaner is formed by spirally twisting a rotor constituting the rotary nozzle, and a brush is spirally planted or a blade is attached to the rotor. It was attached in a spiral shape. For example,
Japanese Patent Publication No. 2-125767 (hereinafter referred to as Example 1), Japanese Patent Publication No. 63-35246 (hereinafter referred to as Example 2) and Japanese Patent Laid-Open No. 61-154607 (hereinafter referred to as Example 3). .

[0003]

The conventional rotary rotor is
A rod-shaped body may be provided on the outer peripheral surface of the rotor, which has multiple projections and grooves spirally provided, and brushes may be provided on the rotor between the projections by spirally bristling along it. ,
A blade formed separately by fitting in the groove is attached in a spiral shape, and the nozzle is assembled.

Therefore, although the rotor is manufactured by the method as shown in Example 1, it is difficult to constantly maintain the dimensional accuracy by twisting and molding the rotor in order to spirally form the protrusions and grooves. However, in particular, providing a groove
It's very difficult. In order to fit the blade in the spiral groove, it is necessary to make the blade with flexible rubber or plastics, so the blade fitted in the groove is easily removed by centrifugal force when the rotating rotor rotates. , Easy to pull out when pulling the blade by hand. To prevent this, the groove structure is complicated, the opening of the groove provided on the outer circumference of the rotor is narrowed, or the size of the groove is increased, but this makes molding difficult and maintains dimensional accuracy. Making it difficult.

To manufacture the rotor, it was usual to extrude foamed thermoplastics by the method as shown in Example 1. The rotor thus created is
There were various problems because the strength was weak, but apart from this, the one that brushed the brush as in Example 1 had a problem that when the rotating rotor rotated and the brush was rubbed on the floor, If there is lint or hair on the brush, it will wind around the brush or rotor and reduce the dust removal effect of the brush, or lose the rotational balance of the rotor, causing vibration and noise when using a nozzle with a built-in rotating rotor. did.

Example 2 is proposed to solve the above problem, and Example 3 is proposed as a structure for attaching the blade to the rotor.
A blade formed by combining the structures shown in Examples 2 and 3 was attached to the rotor as shown in FIG. While this is effective in preventing lint and hair from becoming entangled, it is less effective than a brush in the effect of jumping up and inhaling dust on the floor.

According to the present invention, the degree of freedom in selection of the structure, material, manufacturing method, etc. of the rotor is widened to facilitate manufacturing, and cleaning performance can be improved by preventing lint and hair from wrapping around the rotating rotor. A rotating rotor, which is installed and rotated to improve the cleaning performance of the nozzle that jumps up and inhales dust on the floor, and also prevents the rotating rotor from generating vibration and noise, providing a user-friendly nozzle The purpose is to do.

[0008]

According to the present invention, a brush and a blade are used together in a rotor which constitutes a rotating rotor that rotates in a nozzle according to the present invention, so that the blade prevents the lint and hair from being entangled in the rotating rotor. It scrubs on the floor to improve the dust removal effect.

The rotor is a straight rod-shaped body and has a structure that does not require twisting. The rotor is provided with a plurality of straight grooves having openings on the outer circumference thereof in the longitudinal direction of the rotor.

On each of the outer circumferences of the rotor divided between the grooves of the rotor, a substantially equal number of brushes are dispersed and planted in the longitudinal direction of the rotor. As an example of the arrangement of the brushes, a plurality of spirally brushed brush rows are provided on the outer circumference of the rotor around the rotation axis of the rotor, and the brush rows to be helically planted face each other around the rotation axis of the rotor. In addition, two rows of brushes, which are shifted by a half of the flocking pitch for flocking the brushes, are provided. The larger the number of brushes, the better, but it is usually the minimum number that satisfies the performance.Therefore, when the rotating rotor rotates, do not arrange multiple brushes on the same circumference of the rotor so that they overlap. Make the dust removal effect effective.

A blade is fitted in the groove of the rotor in which the brush is implanted, and an elastic strip-shaped blade is attached to the rotor so as to project from the opening of the groove in a fin shape toward the outside of the rotor. The open end, which is the tip of the part protruding outward of the blade,
As the rotating rotor rotates, it will approach the brush that follows.

The rotor and the brush and the blade are attached to the above-mentioned rotor, and the end portions to which the brush and the blade are not attached are provided at both ends of the rotor, and the brackets which are integrated with the rotary shaft of the rotary rotor are fitted to the end portions. Attach it to make a rotating rotor. The bracket is provided with a protrusion that fits into a plurality of grooves formed in the rotor, and serves as a detent when they are fitted together.

[0013]

It is easy to manufacture a rotor having a straight rod body and a plurality of grooves opening on the outer periphery of the straight rod body are provided straight in the longitudinal direction of the rotor, and it is possible to maintain high dimensional accuracy. it can. If such a rotor is used as a rotary rotor, the rotational balance is good, and vibration and noise are reduced, so that it is easy to use and the life of the rotary rotor is extended.

The method of manufacturing the rotor can be selected from many methods such as extrusion molding and injection molding of plastics and metals, and the material is the same. Therefore, with a material that can increase strength,
A wide range of structure choices can be made such as making the rotor thinner.

By equipping each of the outer peripheral surfaces divided by the plurality of grooves on the outer periphery of the rotor with a substantially equal number of brushes dispersed and flocked, the rotary rotor can be well balanced in rotation. . When the brush is planted on the rotor, the brush can be planted without attaching a blade to the rotor, which facilitates the planting of the brush.

After the brush is applied to the rotor, the blade is attached to the groove of the rotor. The blade protrudes outward in a fin shape from the opening of the groove of the rotor, and when the rotating rotor rotates, the open end, which is the outer tip of this protrusion, is brought close to the brush that rotates following the blade. Tilting and bending prevents lint and hair on the floor from wrapping around the brush or rotor.
The blade is configured like a back vane in the fan of the blower with respect to the rotation direction of the rotating rotor, so it has a structure that reduces air resistance when the rotating rotor rotates and prevents dust on the floor. Work like blowing up,
Make dust soak up and make it easy to inhale.

The rotary rotor is assembled by assembling the brackets, which are integrated with the rotary shaft of the rotary rotor, to the ends of the rotor where the brushes and blades are not provided. Providing a projection that fits in the groove of the rotor in the hole of the bracket that fits with the end of the rotor serves as a detent for the rotor and the bracket.

When the rotating rotor rotates, the blade may be provided only in the vicinity of the brush in the preceding blade and the brush which subsequently rotates. The blade sufficiently serves to prevent the lint and hair from being wrapped around the brush.

Both the brush and the blade are projected to the outside of the rotor. When the rotation amount of the brush is increased to rotate the rotary rotor, the brush rubs the floor to effectively remove dust. It jumps up and inhales with the nozzle, and the blade acts to prevent lint and hair from wrapping around the brush or rotor, improving the cleaning effect and maintaining the rotation balance of the rotating rotor. This prevents the generation of vibrations and noise and prolongs the life of the rotating rotor.

[0030]

The nozzle according to the present invention incorporates the rotary rotor as described above and rotates and uses it, so that the following effects are obtained.

By forming the rotor into a straight rod shape and providing a plurality of grooves open to the outer periphery thereof straight in the longitudinal direction of the rotor, it is not necessary to twist when manufacturing the rotor. It can be selected, it is easy to manufacture, and dimensional accuracy can be secured and maintained accurately. Further, depending on the manufacturing method and the material, the strength can be made larger than that in the conventional example, so that the thickness of the rotor can be made thin. As a result of the above, in combination with the weight reduction of the rotor, the rotation balance of the rotor is improved, the vibration and noise generated in the nozzle that rotates the built-in rotary rotor is reduced, and the feeling of use is good. Etc. will also have a longer life.

Brushes are brushed over the entire circumference on the outer circumference of the rotor divided by a plurality of grooves provided on the outer circumference of the rotor, and blades are attached to the grooves. When moving the rotating nozzle on the floor, rub the floor with a brush to jump up the dust and make it easier to absorb.

Since the blade has a size that protrudes outward of the rotor lower than that of the brush, it is the brush that rubs the floor when the rotating rotor rotates, and long brushed hair like a carpet or With piles, there is some contact. The blade serves to prevent the lint and hair on the floor from wrapping around the brush or rotor. This prevents the brush of the rotating rotor from jumping up dust on the floor and does not impair the rotational balance of the rotating rotor, thus maintaining the cleaning effect of the rotating rotor and vibrating when using the nozzle. And noise will not occur.

When the rotary rotor rotates, the blade preceding the brush is bent at the portion protruding from the rotor toward the subsequently rotating brush so that the tip of the blade approaches the brush. The blate more effectively prevents the lint and hair from wrapping around. Further, the blade becomes like a back vane structure in the blower with respect to the rotation direction when the rotating rotor rotates, reduces air resistance of the blade when the rotating rotor rotates, and also has a carpet with long fluff and piles. The contact resistance is reduced because it is inclined so as not to oppose the rotation direction even when it comes into contact with. As a result, the degree of increase in power consumption of the drive unit can be small, so that the drive unit can have a small output. Therefore, the nozzle incorporating this is small and lightweight, easy to use and economical. Can be something.

By providing a blade that rotates in advance of the brush provided on the outer periphery of the rotor only at the brush portion and its vicinity, it is possible to prevent lint and hair from being wrapped around the brush that continues after the rotation. In addition, the air resistance when the blade rotates is further reduced.

On each of the outer circumferences of the rotor divided by the grooves, a substantially equal number of brushes are provided dispersed in the longitudinal direction of the rotor, and a plurality of brushes are not provided on the same circumference of rotation of the rotor. As a result, when the rotating brush rotates and the brush rubs against the floor, the brush always contacts almost evenly over the entire length of the rotor, so there is no load fluctuation or bias, there is little vibration during rotation, and no noise is generated. . Therefore, the nozzle used while rotating the rotary rotor is easy to use, and the life of the rotary rotor, the bearing, the belt, etc. is prolonged. When the rotating rotor rotates and the brush that is bristling rubs against the floor, multiple brushes are not provided on the same rotation circumference, but each brush overlaps on the same line on the floor. Since it does not rub, the dust removal efficiency is good, and the dust removal effect is excellent even with a small number of brushes.

As an example of the above-mentioned arrangement of the brushes, a rotor is provided in which the brushes are provided spirally around the rotation axis of the rotor around the entire circumference of the rotor, and the brushes are provided so as to be wound around the rotor a plurality of times. FIG. 3A in which the outer circumference of the rotor is developed on a plane is shown, and in order to compare with this, FIG. 3B in which the outer circumference of the rotor is developed on a plane is shown in FIG. The arrangement is shown, and the effects of the rotor in which the brushes are spirally wound in the overlapping windings will be described by comparing these. Both have the same number of brushes, and the arrangement of the brushes on the rotor is approximately even on the outer circumferences G, C, L, N, L and O of the rotor, and they are distributed in the longitudinal direction of the rotor. On the other hand, the brush in the conventional example is divided into the outer circumferences of the rotor corresponding to the outer circumferences G, C, L, N, L and O of the rotor shown in FIG. You can see that they are densely arranged. The effect of the arrangement of the brushes shown in FIG. 3-a is as described above, but in the conventional example, when the rotating rotor rotates and the brush rubs against the floor, the situation in which the brush comes into contact with the floor is , One by one along the rotation axis of the rotation rotor, and thus the rotation rotor generates vibration in the direction of the rotation axis. This also causes noise, so when using the nozzle by rotating the rotary rotor, the nozzle vibrates and generates noise, which is unpleasant to use.
This will adversely affect the life of the rotating rotor, bearings, belts, etc.

End portions without brushes or blades are provided at both ends of the rotor, and brackets which are integrated with a rotating shaft for rotating the rotating rotor are fitted to the terminal portions for assembly. The bracket is provided with a hole to be fitted to the end of the rotor, and one or more projections projecting inward are provided on the inner diameter of the hole, and the projection is fitted to the groove provided on the outer circumference of the rotor. To fix. Although the protrusion and the groove are fitted to each other to form a rotation-stopping structure, the groove is straight, so that a tight fit can be achieved so that engagement with the protrusion can be ensured. Since it can be manufactured with high accuracy, it is possible to fit the bracket and the end portion to reduce the deviation between the rotating shaft and the rotor, and to obtain a rotating rotor with good rotation balance.

As described above, the nozzle according to the present invention has a good rotational balance and is configured so that the load does not fluctuate or move when the brush rubs the floor, and prevents the lint and hair from being entangled in the brush. Since it has a built-in rotary rotor provided with a blade adapted to do so, the nozzle is free from vibration and noise and is convenient to use. Further, because of this, the life of the rotary rotor, bearings, belts, etc. can be extended, and the drive device for the rotary rotor does not need to be particularly large, so the nozzle can be made compact and lightweight, and it is easy to use and economical. It can be manufactured to.
