Abstract

PURPOSE: To surely suck small dirt such as sand or pebbles without scattering the same and to enhance dust collecting efficiency by providing an edge brush having a rotary shaft core inclined with respect to the lateral direction of a floor nozzle main body and driven by a motor in the opening part formed to the side part of the floor nozzle main body and protruding brush bristles outward from the opening part on one end side in the front and rear direction thereof. CONSTITUTION: The rotation of a motor 6 is transmitted to a rotary brush 9 through a belt 13 and the rotary brush 9 and an edge brush 18 are rotated at the same time to scrape up dirt on a surface to be cleaned and this dirt is gathered to a cleaner main body through a suction chamber 4, a joint 7 and a joint pipe 8. When the edge of a wall or the corner part of furniture is cleaned, the brush bristles 20 of the edge brush protruded from an opening part 19 are applied to the edge of the wall or the corner part of furniture to clean the same. Since the edge brush 18 is obliquely provided at this time, dirt such as sand or pebbles near the wall or at the corner part of the furniture is collected into the opening part 19 to be sucked toward the cleaner main body.

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 Conventional floor nozzles for vacuum cleaners of this type are known, for example, as shown in FIGS. 4 to 6.

Inside the main body l, a suction chamber 4 is formed in the front part, and a motor chamber 5 is formed in the rear side of this suction chamber 4. 6 is a motor provided inside this motor chamber 5. 7
A joint is rotatably provided on the floor nozzle main body 1 and communicates with the suction chamber 4, and a joint vibrator 8 is attached thereto to be connected to an extension pipe (not shown) of a vacuum cleaner. 9 is a rotating brush rotatably provided inside the suction chamber 4;
Brush bristles 10 are spirally flocked 1 on the outer periphery.

An edge brush 11 is integrally formed at one end of the rotating brush 9, and the edge brush 11 is disposed in an opening 12 formed on one side of the floor nozzle body 1 and communicating with the suction chamber 4. There is. Reference numeral 13 denotes a belt that serves as a power transmission means and is stretched between the rotating shaft 14 of the motor 6 and the rotating shaft 15 at one end of the rotating brush 9. Note that the end face of the edge brush 11 is configured to protrude from one side 1G of the floor nozzle body 1. Reference numeral 17 is a cord connecting the motor 6 and the power supply section of the main body of the vacuum cleaner.

Problems to be Solved by the Invention In such a conventional vacuum cleaner floor nozzle, the edge brush 11 of the rotating brush 9 is attached to one side 16 of the floor nozzle body l.
Because it protrudes further outward, small dust such as sand and pebbles is blown away by the rotational force of the edge brush 11 during cleaning, and is not sucked into the suction chamber 4 from the island opening 12, but instead is sent to the rear of the floor nozzle body 1. There was a problem with it being spread out.

The present invention solves these problems, and aims to provide a floor nozzle for a vacuum cleaner that ensures that small dust such as sand and pebbles is sucked in without being scattered, and has high dust collection efficiency. It is something to do.

Means for Solving the Problem In order to solve this problem, the present invention forms a suction chamber and a motor chamber in the floor nozzle body, provides a rotating brush in the suction chamber, and provides a mechanism for driving the rotating brush in the motor chamber. An edge brush whose rotation axis is inclined with respect to the width direction of the floor nozzle body and is driven by the motor is provided in an opening formed on the side of the floor nozzle body, and a front and rear bristles of the edge brush are provided. One end in the direction protrudes outward from the opening.

Operation With this configuration, dust such as sand and pebbles on the surface to be cleaned can be reliably collected in the opening without being scattered by the rotation of the edge brush, and a floor nozzle with high dust collection efficiency can be provided.

EXAMPLE Below, an example of the present invention will be explained using the drawings (Figs. 1 to 3).
The explanation will be based on Figure). In the drawings, the same reference numerals as in the conventional example indicate the same members, and detailed explanation thereof will be omitted.

In the figure, a motor 6 is provided in a motor chamber 5 on the rear side of the suction chamber 4 of the floor nozzle body 1 at a position offset to one side 16 of the floor nozzle body 1, and this motor 6 has a rotating shaft 14 that is - It is attached so that it faces the side surface 16 and is tilted so that the rotating shaft 14 faces rearward with respect to the width direction of the floor nozzle body 1. In the conventional example, an edge brush 11 is provided at one end of the rotating brush 9, whereas in this embodiment, an edge brush 18 is provided at the tip of the rotating shaft 14 of the motor 6. This edge brush 18 is disposed in an opening 19 formed at the rear end of one side of the floor nozzle body 1 and communicating with the suction chamber 4 .

This edge brush 18 is also tilted together with the rotating shaft 14, and the bristles 20 on the front end side of the edge brush 18 slightly protrude outward from the opening 19, and the bristles 20 on the rear end side
0 is located within the opening 19. Reference numeral 21 denotes a roller for straightening the belt 13 stretched between the rotating shaft 14 of the motor 6 and one end of the rotating brush 9, and straightens the belt 13 so that it hangs approximately at right angles to the rotating shaft 14 and the rotating brush 9. are doing. The motor 6 is configured to rotate clockwise when viewed from the negative side surface 16. The other configurations are the same as the conventional example.

To explain the operation in the above configuration, the motor 6 rotates when the power of the vacuum cleaner body is turned on. The rotation of the motor 6 is transmitted to the rotating brush 9 via the belt 13, and the rotating brush 9 and the edge brush 18 rotate simultaneously to scrape up dust from the surface to be cleaned.
It passes through the joint 7 and the joint vibe 8 and is collected into the vacuum cleaner body. Therefore, when cleaning the edges of a wall or a corner of furniture, the bristles 20 of the edge brush 18 protruding from the opening 19 are applied to the edge of the wall or a corner of the furniture. Since the opening 19 is provided at an angle, dust such as sand and pebbles from walls and corners of furniture is collected inside the opening 19 and sucked into the cleaner body.

Effects of the Invention As described above, according to the present invention, the edge brush is provided in the opening formed in the side part of the floor nozzle body so that the axis of rotation thereof is inclined with respect to the width direction of the floor nozzle body,
One end side of the brush bristles of this edge brush in the front and back direction protrudes outward from the above-mentioned space, so that dust such as sand and pebbles on the surface to be cleaned is not scattered by the rotation of the edge brush, and can be inserted into the opening. It is possible to provide a floor nozzle that can reliably collect dust and has high dust collection efficiency.
