Description

[Detailed description of the invention] Industrial applications The present invention relates to a floor nozzle for a vacuum cleaner.

2. Description of the Related Art As a conventional floor nozzle for a vacuum cleaner, one constructed as shown in FIG. 5, for example, is known.

To explain based on FIG. 5, a rotating brush 3 whose both ends are supported by bearings 2 is provided inside the front end of the floor nozzle body 1, and this rotating brush 3 has brush bristles 4 diagonally implanted. There is. Reference numeral 5 denotes a bumper provided to secure the front wall outer surface and the left and right side wall outer surfaces at the front end of the floor nozzle main body 1. In addition, as another conventional example, a rotating brush with diagonally flocked brush bristles is supported by a bearing inside the floor nozzle body at a position slightly closer to the center than both ends of the rotating brush, and Although there are some configurations in which a rotating brush is present at different positions, in both of these conventional examples, both ends of the rotating brush are covered by both left and right walls of the floor nozzle body.

Problems to be Solved by the Invention In such a conventional floor nozzle of a vacuum cleaner, even if the brush bristles 4 are flocked diagonally, the cleaning range at both ends of the rotating brush 3 is the left and right sides of the floor nozzle body 1. There is a problem in that when cleaning the wall edges up to the inner surfaces of both side walls, it is impossible to clean the abrasions on the left and right side walls of the floor nozzle body 1 and the thickness of the bumper 5 provided on the outside thereof.

The present invention solves these problems, and aims to provide a floor nozzle for a vacuum cleaner with good dust collection performance, which can reliably push out the parts that contact the outer surfaces of the left and right walls of the floor nozzle. This is the purpose.

Means for Solving the Problem In order to solve this problem, the present invention provides a rotating brush inside the floor nozzle body at a position facing the suction port formed in the floor nozzle body, and also includes a rotating brush at both ends of the floor nozzle body. Located in openings formed on both left and right sides of the floor nozzle body, brush bristles are provided on the outer periphery of both ends of the rotating brush, and in a part of the floor nozzle body immediately before the bristles touch the ground with respect to the rotational direction of the rotating brush, A guide portion is provided that contacts the brush bristles and tilts the brush bristles outward.

Effect With this configuration, the brush bristles are forcibly tilted outward by the guide section provided on a part of the floor nozzle body just before they touch the ground, and because they touch the ground in a straight line, the restoring force of the bristles causes the floor nozzle body to Dust can be sucked into the floor nozzle body by drawing the dust into the floor nozzle body from the outside.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

In FIGS. 1 to 4, 11 is a vacuum cleaner body, which has a motor chamber 13 with a built-in motor 12 at its lower end, a dust collection chamber 14 above this motor chamber 13, and a dust collection chamber 14 at its upper end. A handle 15 is provided that protrudes from the motor chamber 13. A motor exhaust port 1 is provided at the upper front end of the motor chamber 13.
6 is formed, and this motor exhaust port 16 and the dust collection chamber 1
4 is covered by M17 from the front. Further, this lid 17 is provided with a partition wall 18 that projects inward, and this partition wall 18 partitions the motor exhaust port 16 and the dust collection chamber 14. Reference numeral 19 denotes a beneficial exhaust port formed at the lower end of 117 so as to communicate with the motor exhaust port 16, and an exhaust filter 20 is removably attached to the inside thereof. Reference numeral 21 denotes a floor nozzle body which is rotatably attached to the lower end of the vacuum cleaner body 11. A suction port 22 is formed on the lower surface of the front end, and a rotating brush 23 is built in at a position facing the suction port 22. , this rotating brush 23 is configured to be driven by the motor 12 via a belt 24.

Reference numeral 25 indicates a hose whose one end passes backward into the suction port 22 and whose other end communicates with a dust collection bag 26 provided inside the dust collection chamber 14. Reference numeral 27 indicates a front wall outer surface and left and right side wall outer surfaces at the front end of the floor nozzle main body 21. It is a bumper installed to cover the

By the way, the rotating brush 23 is supported by a bearing 28 located inwardly from both left and right sides of the floor nozzle body 21, and its end face is located outside the bearing 28 on the outer surface of both left and right walls of the floor nozzle body 21, and this rotation On the outer periphery of both ends of the brush 23, brush bristles 29 that project obliquely outward are implanted in a circular shape when viewed from the side. Incidentally, inside the bearing 28, the rotating brush 23 has divided bristles 30 similar to the conventional brush bristles and is implanted therein. Openings 31 having approximately the same diameter as the brush bristles 29 at both ends are formed in the left and right side walls of the floor nozzle body 21 and the bumper 27, which roughly face both ends of the rotating brush 23. A guide portion 32 is formed in a part of the floor nozzle body 21 immediately before the brush bristles 29 touch the ground with respect to the direction (arrow direction in FIG. 4), which contacts the brush bristles 29 and tilts the brush bristles 29 further outward. . Although not shown in the drawings, a passage is formed in the bearing 28 so that the outside and the inside of the bearing 28 communicate with each other.

To explain the operation in the above configuration, the motor 12
The rotating brush 2 is rotated through the belt 24 by driving the
3 rotates, and at the same time, the dust-containing air sucked in by the rotation of the motor 12 passes through the hose 25 from the suction port 22 and enters the dust collection chamber 1.
The dust is collected in the dust collection bag 26 inside the dust collection chamber 1.
4 enters the motor chamber 13 from the lower end of the motor exhaust port 1
6, is filtered by an electric filter 20 at a lid exhaust port 19, and is discharged to the outside as clean air.

On the other hand, due to the rotation of the rotating brush 23, the bristles 2
9 rotates close to the opening 31, but the plush bristles 2
The guide portion 32 formed just before the brush 9 touches the ground causes the brush bristles 29 to further incline outward.

When the brush bristles 29 come off the guide part 32 and come into contact with the floor surface, the restoring force of the brush bristles 29 draws dust from the outside toward the inside of the floor nozzle body 21. This dust is collected through a passage formed in the bearing 28 and into a dust collecting bag 26 via a hose 25. This makes it possible to clean the entire width of the floor nozzle, and also to reliably clean the portions that come into contact with both left and right sides of the floor nozzle (wall edges, etc.).

By the way, in the embodiment described above, the brush bristles 29 are planted on the outer periphery of both ends of the rotating brush 23, but in addition to the bristles, a separate member may be used to provide the brush bristles.

Effects of the Invention As described above, according to the present invention, both ends of the rotating brush are located at the left and right openings of the floor nozzle body, and bristles are provided at both ends of the rotating brush, so that the entire width of the floor nozzle is covered. The brush bristles are tilted outward by a guide provided on the floor nozzle body just before they touch the ground, and then touch the ground immediately after that.
Due to the restoring force of the brush bristles, dust can be drawn into the floor nozzle body from the outside of the floor nozzle body, making it possible to reliably clean walls, for example.
