Abstract

(57) [Abstract] [Purpose] To provide a cleaner having a wheel structure that does not stain or damage the floor surface or damage the wheel outer peripheral surface. [Structure] A wheel 12 has a hollow portion 13 inside, a large number of holes 15 in an outer peripheral surface 14, and is supported by an axle 10. The axle 10 has a hollow portion 11 inside and is arranged so as to communicate with the hollow portion 13 and the branch pipe line 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vacuum cleaner, and more particularly to a dust suction structure for a vacuum cleaner.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, the negative pressure air 20 from the suction motor is supplied only to the suction portion 21 and not even to the wheel structure 22. Therefore, the dust 25 from the floor surface 24 adhered to the outer peripheral surface 23 of the wheel structure 22.

[0003]

[Problems to be solved by the device]

 In the conventional vacuum cleaner, dust 25 adheres to the outer peripheral surface of the wheel of the wheel structure 22, so that the floor surface 24 is soiled, damaged, or scratched on the outer peripheral surface of the wheel, resulting in unstable running performance. There was a possibility. Therefore, an object of the present invention is to provide a cleaner in which dust does not easily adhere to the wheel outer peripheral surface in order to prevent the floor surface from being soiled or damaged, or the wheel outer peripheral surface from being damaged.

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, in order to achieve the above-mentioned object, a wheel of a wheel structure is formed in a hollow shape having a plurality of holes on an outer peripheral surface thereof, and the hollow portion is provided between a suction portion for sucking dust and a dust pack. In addition, an axle having a pipe-shaped space of the wheel structure is arranged between the hollow part of the wheel and the pipeline so that they can communicate with each other.

[0005]

[Action]

 According to this invention, the dust on the floor contacting the wheels is supplied from the suction motor through the many holes on the outer peripheral surface of the wheel through the pipe line between the suction part and the dust pack and the pipe-shaped space of the axle. It is sucked in by negative pressure air and prevents dust from adhering to the outer peripheral surface of the wheel.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. In the figure, the vacuum cleaner 1 includes a suction motor 2, a suction unit 3, a dust pack 4, an exterior structure 5 surrounding them, and a wheel structure 7 for moving the above-mentioned components along a floor surface 6 for traveling. I have it. A branch pipe 9 is drawn out from a pipe 8 connecting the dust pack 4 and the suction unit 3, and the other end of the branch pipe 9 is pipe-connected to a hollow hollow portion 11 of an axle 10 of a wheel structure 7. There is. Wheels 12 are rotatably engaged with both ends of the axle 10 in an airtight manner. The wheel 12 is provided with a hollow portion 13 which is pipe-connected to the pipe-shaped space 11, the side surface 16 of the wheel 12 is sealed so that air does not flow, and the outer peripheral surface 14 of the wheel 12 is The outer peripheral surface 14 of the wheel 12 excluding the outer peripheral surface 14 near the floor surface 6 is located close to the outer peripheral surface 14 in order to prevent the circulation of air in the outside and a large number of holes 15 other than the portion contacting the floor surface 6. A cover 17 is provided. The dust 18 on the floor 6 is sucked through the holes 15 in the outer peripheral surface 14 of the wheel 12 by supplying the negative pressure air 19 from the suction motor 2 to the outer peripheral surface 14 of the wheel 12, and the hollow portion 13 of the wheel 12 and the axle 10. The dust is accumulated in the dust pack 4 through the pipe-shaped hollow portion 11, the branch pipe line 9 and the pipe line 8. Therefore, according to the present invention, the dust 18 on the floor 6 is sucked into the wheel 12 without adhering to the outer peripheral surface 14 of the wheel 12.

[0007]

[Effect of the device]

 As described above, according to the present invention, the structure in which the negative pressure air is supplied from the suction motor to the wheel portion of the vacuum cleaner makes it possible to prevent dust from adhering to the outer peripheral surface of the wheel, and thus the floor. The possibility of soiling or scratching the surface or damaging the wheel outer peripheral surface is reduced.
