JPH05293066A - Suction hole for vacuum cleaner - Google Patents

Abstract

PURPOSE:To eliminate occurrence of trouble caused by entanglement of waste threads and to improve durability by preventing the waste threads from entering between a rotating body and a brush cover in a vaccum cleaner provided with a sucking hole having a rotating brush. CONSTITUTION:By providing a guide wall 29 provided by cutting and rising on a part of a brush cover 26 preventing a hand from being brought into contact with a rotating body 22 wherein a brush is piled on the periphery in such a way that it is set in the rotating direction of the rotating body 22 and this side in the rotating direction is faded to the rotating body 22 side and the front side in the rotating direction is faced to the outside of a floor nozzle 6 and it is inclined, it is possible that waste 28 entangled on the brush 23 such as waste threads is discharged outside from a slit part along the slope of the guide wall 29 by the rotating force of the rotating body 22 and clogging at the rotating part is removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner having a suction port having a rotating brush.

[0002]

2. Description of the Related Art A conventional vacuum cleaner suction port will be described below.

As shown in FIGS. 4 to 8, reference numeral 1 is a handle portion having a handle 2. 3 is a power cord, 4 is an upper cover, and 5 is a dust collector cover. 6 is a floor nozzle,
Reference numeral 7 is a rotating brush, and 8 is a dust collector main body. Reference numeral 9 is an electric blower, and 10 is a hose. Reference numeral 11 is an air intake portion, 12 is a paper bag, and 13 is a belt for transmitting the rotation of the electric blower 9 to the rotating brush 7 of the floor nozzle 6. Reference numeral 14 is a back cover attached to the floor nozzle 6, and 15 is a cutout portion provided in the floor nozzle 6. Reference numeral 16 is a brush provided on the rotary brush 7, and the rotary shaft 17 is press-fitted into a bearing 19 of a bearing 18 and rotatably attached to the floor nozzle 6. The end support 20 of the rotary brush 7 is attached to the rotary shaft 17 by a pin 21. A resin-made rotating body 22 having brushes 23 planted on its outer periphery is fixed to an end of the rotating brush 7 by a screw 24 on a rotating shaft 17. Reference numeral 25 denotes a rib formed on the floor nozzle 6, and a bearing 18 having a rotating shaft 17 attached thereto is attached to the back lid 14 with the rib. Reference numeral 26 is a brush cover made of sheet metal which prevents the rotating body 22 from being touched by the hand, and is attached by the ribs 27 of the floor nozzle 6. 28 is hair and lint.

With the above configuration, the brush 23 can remove dust in the corners that cannot be removed by the rotating brush 7.

[0005]

However, in the above-mentioned conventional structure, hair and lint are entangled in the brush and enter between the side surface of the rotating body and the brush cover to stop the rotating body due to resistance due to rotation, and further There was a problem that the side surface became hot and melted. The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a suction port for an electric vacuum cleaner which prevents a failure due to entanglement of lint and the like and has good durability.

[0006]

In order to solve this problem, the suction port for an electric vacuum cleaner according to the present invention has a part of which the front side in the rotating direction of the rotating body is directed to the rotating body side and the rotating body rotates. The brush cover is provided with a guide wall having a slit formed by inclining the front side toward the outside of the floor nozzle.

[0007]

With this structure, hair and lint that are entangled in the brush are discharged from the slit portion to the outside of the floor nozzle along the inclination of the guide wall by the rotational force of the rotating body.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 showing an embodiment of the present invention, the same parts as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 1 to 3, a guide wall 29 provided by cutting and raising a part of the brush cover 26 is aligned with the rotating direction of the rotating body 22, and the front side in the rotating direction of the rotating body 22. It is formed by inclining the front side in the rotation direction toward the outside toward the outside of the floor nozzle 6.
The slit portion 30 is created by cutting and raising a part of the brush cover 26.

As described above, according to this embodiment, by providing the brush cover provided with the guide wall having the slit portion in a part thereof, the hair and the lint that are entangled in the brush due to the rotating force of the rotating body are provided on the guide wall. It can be discharged to the outside of the floor nozzle from the slit part along the inclination. Therefore, it is possible to prevent clogging of the rotating portion with dust, and prevent a failure such as the rotating body stopping or the rotating body melting due to frictional heat.

[0011]

As is apparent from the above description of the embodiments, the present invention has a part in which the front side in the rotating direction of the rotating body is directed toward the rotating body and the front side in the rotating direction of the rotating body is the floor nozzle. With a configuration that includes a brush cover that has a guide wall that has a slit portion that is formed to incline toward the outside of the, an excellent vacuum cleaner suction port that can prevent failure and improve durability can be provided. It can be realized.
