Abstract

PURPOSE:To achieve higher dust collection efficiency by arranging rotary brushes, the one with a larger diameter and the other with a small diameter, as driven with one motor in front and rear while furthermore providing a partition between paths from floor surface suction ports therefor and forming guide paths. CONSTITUTION:First and second rotary brushes 4 and 5 are rotated in a floor nozzle body 1 with one motor 2 through a pulley and a belt 3. The first rotary brush 4 is made with a small diameter to form a first floor surface suction port 8. The second rotary brush 5 is made with a larger diameter than that of the brush 4 to form a second floor surface suction port 9. A partition 7 is provided between the first and second floor surface suction ports 8 and 9 to form a guide path 11 so that air sucked converges at a common suction port 10. A floor nozzle body 1 advances or retracts along a floor surface. Thus, the dust which the first or second rotary brush 4 or 5 fails to collect is collected with the second or first rotary brush 5 or 4 thereby achieving higher dust collection efficiency with a smaller size.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric floor nozzle which improves the dust collecting performance of a vacuum cleaner and the cleaning work.

[0002]

2. Description of the Related Art A floor nozzle of a conventional vacuum cleaner generally uses one rotating brush.

[0003]

Such a floor nozzle having a single rotating brush has a low suction force and a rechargeable self-propelled cleaning having a limited cleaning time, especially for a carpet surface. When cleaning is performed, performance is insufficient and efficient cleaning cannot be performed. That is, in a vacuum cleaner having a low suction force, a large amount of scraped dust is caught in the rotation direction without being sucked from the suction port and returns to the cleaning surface again.
Therefore, the user needs to reciprocate the floor nozzle several times. In addition, since the current self-propelled vacuum cleaner does not have a function of determining whether or not dust has been sucked, it is required to reliably suck dust with one movement. Therefore, it is necessary to increase the suction force, but on the other hand, there is a problem that the cleaning time and the cleaning area are limited.

SUMMARY OF THE INVENTION The present invention is intended to solve the problems of the conventional structure, and a first object thereof is to provide an electric floor nozzle having high dust collection efficiency. A second object is to provide an electric floor nozzle that can reliably collect lint and the like. A third object is to provide an electric floor nozzle that is more compact and has high dust collection efficiency.

[0005]

The first means of the present invention for achieving the first object is to provide a first floor between the first and second rotary brushes driven by an electric motor and the rotary brushes. A partition wall provided so as to form the surface suction port and the second floor suction port, and to form a guide passage communicating with the suction port of the first rotary brush provided on the second rotary brush. The electric floor nozzle has the diameter of the first rotary brush smaller than that of the second rotary brush.

A second means of the present invention for achieving the second object is, in addition to the constitution of the first means of the present invention,
The first rotating brush is an electric floor nozzle provided with a blade brush continuous in the axial direction, and the second rotating brush is provided with a brush constituted by flocking.

A third means of the present invention for achieving the third object is to provide first and second rotary brushes driven by an electric motor or the like, a partition wall provided between the rotary brushes, and a second partition. And a guide passage leading to the suction port of the first rotating brush provided in the rotating brush, the diameter of the first rotating brush is set larger than the second rotating brush, and the second rotating brush is the floor. The surface is not grounded, the lower half is located so that it is the upper half of the first rotating brush, and the outer wall that covers the lower part of the second rotating brush is integrated with the partition wall, and it is located at the position where both rotating brushes overlap The partition wall is an electric floor nozzle having an opening.

[0008]

The first means of the present invention acts to enhance the dust collection performance. That is, the dust not sucked by the first rotating brush is sucked by the second rotating brush.

The second means of the present invention is such that the first rotary brush sucks in thread dust and the like, and thereafter the second rotary brush sucks up the remaining dust.

Further, the third means of the present invention is that the dust that is scraped up by the first rotary brush and caught on the opposite side without being sucked by the suction port is splashed upward by the second rotary brush to make the first rotation. The suction path provided on the brush acts so as to suck the brush.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first means of the present invention will be described below with reference to FIG. The floor nozzle body 1 includes an electric motor 2
It has a first rotary brush 4 and a second rotary brush 5 that are driven by a belt 3 that transmits the rotation, and a connecting pipe 6 that is connected to a cleaner body (not shown).
The first rotary brush 4 has a smaller diameter than the second rotary brush 5. The partition wall 7 separates the first rotary brush 4 and the second rotary brush 5 and constitutes a first floor surface suction port 8 and a second floor surface suction port 9. Further, a guide passage 11 communicating with the suction port 10 of the first rotary brush 4 is formed on the second rotary brush 5. In addition, in order to configure the first floor suction port 8 and the second floor suction port 9, the first rotating brush 4 has a smaller diameter than the second rotating brush 5 in this embodiment. As a whole, we are trying to reduce the size.

The operation of this embodiment will be described below. The dust scraped up by the first rotating brush 4 is guided from the first floor suction port 8 to the suction port 10 connected to the connection pipe 6. Further, the dust sucked through the second floor suction port 9 is introduced into the suction port 1 through the guide passage 11 formed in the second rotary brush by the partition wall 7.
Lead to zero. Thus, the dust is sucked into the cleaner body through the connection pipe 6. That is, according to the configuration of the present embodiment, the dust that the first rotary brush 4 could not collect is scraped up and collected by the second rotary brush 5. On the contrary, the dust that the second rotating brush 5 cannot collect is scraped up by the first rotating brush 4. That is, it is possible to surely collect dust by a single operation of the user, and to realize an electric floor nozzle having extremely high dust collection performance. Therefore, the electric floor nozzle of this embodiment is suitable for a self-propelled cleaner.

Next, an embodiment of the second means of the present invention will be described with reference to FIG. In this embodiment, the first rotating brush 4 has a blade brush 12 that is continuous in the axial direction. The second rotating brush 5 has a brush 13 formed by flocking. In this case, in the present embodiment, the first rotary brush 4 is configured to have a smaller diameter than the second rotary brush 5, and the overall size is reduced.

The operation of this embodiment will be described below. Since the first rotary brush 4 has the blade brush 12 and has a small diameter, it can collect dust such as yarn dust. In this case, since the diameter of the first rotating brush 4 is small, the inclusion of dust is unlikely to occur. In this way, after the dust such as thread dust is collected by the first rotating brush 4, the remaining dust is collected by the second rotating brush 5.

According to this embodiment, dust is collected by the first rotary brush 4 having the blade brush 12 having a small amount of thread dust and the like, and then a flocking brush having a high scraping effect is provided. Since the second rotating brush 5 that is installed collects dust, the first and second rotating brushes 4
The diameters of both 5 and 5 can be reduced, and the floor nozzle can be downsized as a whole.

Next, an embodiment of the third means of the present invention will be described with reference to FIG. In the present embodiment, the diameter of the second rotary brush 5 is equal to or smaller than the diameter of the first rotary brush 4, and is configured to float above the floor surface. That is, the lower half of the second rotary brush 5 is arranged to be the upper half of the first rotary brush 4, and the partition wall 7 is provided between the first and second rotary brushes 4 and 5. The partition wall 7 forms a guide passage 11 on the first rotary brush 4 that communicates with the second rotary brush 5. Further, the partition wall 7 has an opening 14 at a position where the first rotary brush 4 and the second rotary brush 5 overlap each other.

The operation of this embodiment will be described below. According to the present embodiment, the first rotating brush 4 that has been caught in the rotating direction without being sucked from the suction port 10 among the dust that has been splashed up from the first rotating brush 4 is not absorbed by the second rotating brush 5 from the opening 14.
It is repelled by and is collected through the guide passage 11 from the suction port 10 to the cleaner body side. in this case,
Since the second rotary brush 5 is not grounded on the floor surface and merely repels dust, the brush diameter can be reduced. For this reason, the floor nozzle can be downsized as a whole, and accordingly, the input of the electric motor 2 as a drive source can be low. That is, the electric floor nozzle of this embodiment is suitable for a vacuum cleaner that requires a low input and a rechargeable vacuum cleaner that has a limited cleaning time.
