Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner equipped with eleven brushes for removing dust adhering to a surface to be cleaned, and is particularly characterized by a stop configuration of the rotating brush. It is.

Conventional configuration and its problems Conventionally, dust attached to the surface to be cleaned has been removed by 1% from the surface to be cleaned.
2. Description of the Related Art Vacuum cleaners equipped with rotating brushes that rotate are known.

The configuration will be explained based on FIGS. 1 and 2.

In the figure, 1 is a vacuum cleaner main body, and an electric blower 2 is housed inside the cleaning main body 1. Reference numeral 3 designates a floor nozzle, inside which a rotary brush 4 is rotatably supported by a bearing 6, and the rotary brush 4 is rotated by a rotary brush type 'fUtlfie and a belt 7. The dust separated from the pupil plane by the rotating brush 4 passes from the suction port 8 through the suction passage 9, and is sucked into a collection chamber 11'v formed below the filter 10.

Reference numeral 12 denotes a clutch lever that stops the rotation of the rotating brush 4 when the surface to be cleaned does not require the rotating brush 4, such as a floor or a tatami mat.

However, in the above configuration, since there are two electric motors, an electric blower and a rotating brush type UJ machine, the weight becomes heavy and the cost increases. Also, mold m for rotation plan
) Because the machine was stored away, the floor nozzle had the disadvantage of making noise.

Furthermore, when the rotating brush is left spinning due to forgetting to shift the clutch lever or switch, there is a problem in that it damages the carpet on the floor.

Purpose of the Invention In order to solve the above-mentioned drawbacks, the present invention drives the blower and rotation plan with one electric I#1 machine, reduces weight and cost, downsizes the floor nozzle, and stands the vacuum cleaner body upright. In this case, the clutch is disengaged to stop the rotating brush from rotating to prevent the rotating brush from damaging the floor surface.

Structure of the Invention In order to achieve this object, the vacuum cleaner of the present invention includes a vacuum cleaner body with a built-in electric blower, a floor nozzle with a built-in rotating brush that is rotatably attached to the vacuum cleaner body, and a floor nozzle with a built-in rotating brush. It consists of a power transmission shaft and a clutch mechanism that transmits the rotational force of an electric blower to a rotating brush 1.

With this configuration, the power of the electric blower can be transmitted to the rotating brush through the power transmission shaft while the electric blower is housed inside the vacuum cleaner body. This eliminates the need for a rotary brush type fiIJ machine, reducing weight and cost. can be made smaller. Furthermore, the clutch mechanism is disengaged as a groove ffl when the cleaning body is erected, resulting in a structure that does not damage the floor surface.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 3 to 6, 13 is a vacuum cleaner body, and 14 is a floor nozzle. An electric blower 16 is vertically provided on the inside upper part of the cleaner body 13, and a first shaft 17 is supported by a first bearing 18 in parallel with the electric blower shaft 16.

A driving pulley 19 is housed in the first shaft 17, and the electric blower shaft 16 and the driving pulley are housed therein. It is connected to an intermediate shaft 23 via a clutch mechanism 22 provided inside.

A rotating plan 24 is rotatably mounted parallel to the intermediate shaft 23, and a rotating brush belt 26 is stretched between the intermediate shaft 23 and the rotating brush boob IJ-25.

The cleaner body 13 and the floor nozzle 14 are rotatably connected through a connecting pipe 27. A first cylindrical cam 28 is provided on the clutch 22 side of this connecting pipe 27, and is engaged with a second cylindrical cam 29 provided on the clutch 22, so that the vacuum cleaner main body 1
3 is placed upright, the first cylindrical cam 28 acts on the second cylindrical cam 29 to separate one clutch of the clutch mechanism 22 from the other, so that the clutch mechanism 22 is disengaged.

is an operation knob for turning on and off the clutch mechanism 22, which can be operated manually.

Regarding the electricity (11 removal machine) constructed as above, the %J operation thereof will be explained below.

The output of the electric blower 15 installed inside the vacuum remover body 13 is

transmitted to. The rotational force transmitted to the power transmission shaft 21 is
Via the clutch mechanism 22 inside the floor nozzle 14, the intermediate shaft 23 is transmitted to the rotating brush 24 via the rotating plan belt 26 and the rotating brush pulley 25, and is rotated.

The dust separated from the surface to be cleaned by the rotating brush 24 is
Dust collection chamber 32 below filter 33 through connecting pipe 27
It accumulates.

When cleaning a surface that does not require the rotating brush 24, such as a trench, the clutch mechanism 22 is disengaged using the operating knob 33.

In addition, when the rotating brush 24 is required, the vacuum cleaner main body 1
3 is placed upright, the first cylindrical cam 28 provided on the connecting pipe 27 engages with the second cylindrical cam 29 provided on the clutch mechanism 22, turning off the clutch device η22 and turning the rotary brake/
24 stops rotating.

As described above, according to this embodiment, by transmitting the power from the electric blower 15 to the rotating brush 24 using the power transmission shaft 21, the electric blower 15 is used as a magnet to make the vacuum cleaner body 13 thinner. By shortening the path from the suction port to the dust collection chamber 32 and reducing pressure loss in the suction path, the electric blower 15 can drive the fan 724 mentioned above. Therefore, an electric motor for driving the per-plate brush is not required, and m/Q and cost can be reduced, and the floor nozzle 14 can be made smaller. In addition, even if the switch on the vacuum cleaner body 13 or the switch is turned off and the rotary brush 24 is left spinning, the rotation of the rotary brush is automatically turned off, so there will be no scratches on the floor. No attachment occurs.

Effects of the Invention As described above, the vacuum cleaner of the present invention uses a power transmission shaft to transmit power from the electric blower inside the vacuum cleaner body to the rotating plane in the floor nozzle, and is composed of one electric w'J machine. Since it is possible to reduce the m- and cost, it is also possible to downsize the floor nozzle. In addition, if you stand the vacuum cleaner upright, even if you leave it with the rotating brush spinning, the clutch will disengage, so there will be no damage to the floor.
