Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical vacuum cleaner used in general households.

[0002]

2. Description of the Related Art Conventionally, a vertical vacuum cleaner of this type has a structure as shown in Japanese Utility Model Laid-Open No. 52-112168.

That is, in FIG. 4, a handle 5 is attached via a pipe 4 to the rear of a cleaner main body 3 containing a dust collecting chamber 1 and a motor 2. A floor nozzle main body 6 is disposed below the cleaner main body 3, and the floor nozzle main body 6 is provided.
Was rotatably provided on the cleaner main body 3. In addition,
Reference numeral 7 designates a roller for left-right symmetry, which is provided on the floor nozzle body 6.

[0004]

However, in such a conventional structure, since the roller 7 is not rotatably provided, the operation of moving the floor nozzle main body 6 back and forth can be facilitated. However, it was difficult to move the floor nozzle body 6 diagonally or laterally. When there is dust laterally or diagonally near the floor nozzle body 6, first move the floor nozzle body 6 to a position facing the dust, and then move the floor nozzle body 6 in the front-back direction. Therefore, there is a problem that cleaning operation becomes long and usability is poor.

Therefore, the present invention is intended to solve the above problems, and an object of the present invention is to provide a vertical vacuum cleaner having a floor nozzle main body that is movable in an oblique direction and is very convenient. is there.

[0006]

In order to achieve the above-mentioned object, the technical means according to claim 1 comprises a cleaner main body provided with a fan motor and a suction side of a lower part of the cleaner main body. A flexible floor nozzle main body is connected, a handle is arranged on the upper part of the cleaner main body, and a rotatable caster roller for traveling is arranged on the lower part of the cleaner main body.

In the technical means according to the second aspect of the present invention, a pair of left and right caster rollers are arranged on both sides of the lower portion of the floor nozzle body.

According to a third aspect of the present invention, the small wheel of the caster roller arranged in the lower part of the cleaner main body is arranged at a position behind the center of gravity of the cleaner main body.

According to a fourth aspect of the present invention, in the tilting range in which the cleaner main body moves from the substantially upright state to the ground contact with the floor surface, the tilting locus of the small wheel of the caster roller is the rear of the floor nozzle body. It is arranged inside of the body.

[0010]

With the above construction, the rotatable caster roller for traveling is arranged in the lower part of the cleaner, so that the handle can be advanced when the floor nozzle body needs to be changed in direction while cleaning the floor. If pushed in the direction, the rotatable caster roller follows the desired direction, and the cleaning operation range on the floor surface becomes larger. Further, by arranging the caster roller also under the floor nozzle main body, lateral movement becomes very easy, usability is improved, and efficient cleaning is obtained.

Further, the small wheel of the caster roller is located at a portion rearward of the center of gravity of the cleaner, and the tilting locus is located inside the body behind the floor nozzle body, so that the fulcrum of the cleaner is a fulcrum. The area can be made large and the stability becomes good. Further, even if the main body of the vacuum cleaner is moved from the almost upright state to the ground contact with the floor surface, the small wheel of the caster roller does not damage the body behind the floor nozzle body.

[0012]

An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1 to FIG. 3, 11 is a dust collecting chamber 1
Paper bag 13 attached to 2 and fan motor 1
4. It is mainly a vacuum cleaner having a cord winding device 15 built in vertically. The paper bag 13 can be replaced by attaching and detaching the lid 16. On the suction side of the cleaner body 11,
The floor nozzle main body 17 is connected, the rotary brush 18 is built in, and is rotated by a drive motor (not shown) via a belt 19.

Bumpers 20 are provided on the front and side surfaces of the floor nozzle body 17. Reference numeral 21 is a suction port for sucking dust on the floor.

A pipe 22 is provided at the rear of the cleaner main body 11, and a handle 23 is provided above the pipe 22. A floor nozzle main body 17 and a cleaner main body 11 are rotatably provided around a rotary shaft 24 below the cleaner main body 11.

A rotatable caster roller 25 for traveling is attached to the lower part of the cleaner main body 11, and the caster roller 25 comprises a caster cover 26 and a small wheel 27.

When the caster roller 25 is rotated forward, the end face of the small wheel 27 is located at a position behind the center of gravity 28 of the cleaner main body 11. Also,
In the tilting range in which the cleaner main body 11 moves in the direction A in FIG. 2 from the substantially upright state to the ground contact with the floor about the rotating shaft 24, the tilting locus 29 of the small wheel 27 of the caster roller 25 moving at the same time. Is the floor nozzle body 17
It is arranged inside the rear body 30.

Therefore, since the fulcrum area for supporting the cleaner main body 11 can be made large, the stability can be improved. Furthermore, even if the cleaner body 11 is moved in the A direction,
The small wheel 27 of the caster roller 25 is the floor nozzle body 17
Since the body 30 at the rear is not touched, there is no need to worry about scratching.

Next, a pair of left and right recesses 31 are provided on both sides of the lower surface of the floor nozzle body 17, and rotatable caster rollers 25 are attached to the recesses 31.

The above is the configuration of the present invention, and the operation will be described below. When the floor nozzle main body 17 is moved back and forth in the front-back direction when cleaning the floor surface, the handle 23 in FIG. 3 may be pushed in the B direction. Next, when dust is present laterally or obliquely near the side of the floor nozzle body 17, the handle 23 is pushed in the C direction to lower the bottom surface of the cleaner main body 11 and the bottom surface of the floor nozzle body 17. The rotatable caster roller 25 provided at the position follows the pushing direction, and the floor nozzle body 17 can move in the lateral and diagonal directions. As described above, the vertical vacuum cleaner, which has been very difficult to change the direction in the related art, can be easily moved diagonally and laterally, so that the cleaning operation range is widened and the usability is significantly improved.

[0021]

As described above, according to the present invention, rotatable caster rollers are arranged on both sides of the lower surface of the cleaner main body and the lower surface of the floor nozzle main body so that the caster rollers can be moved diagonally and laterally. Can be easily performed, and it is not necessary to move the floor nozzle main body to a position facing the dust, and the cleaning operation range is widened, and the usability is greatly improved. Also, the small wheels of the caster rollers are arranged at a position behind the center of gravity of the cleaner, and the tilting locus of the small wheels of the caster rollers is arranged inside the body behind the floor nozzle body. Therefore, the fulcrum area supporting the main body of the vacuum cleaner can be made large, and the stability becomes good. further,
The small wheels of the caster rollers do not touch the body behind the floor nozzle body, and there is no risk of scratches.
