Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner equipped with a rotating brush for removing dust attached to a surface to be cleaned.

2. Description of the Related Art Structures of Conventional Examples and Problems There have been conventionally known electric cleaners equipped with a rotating brush that separates dust attached to a surface to be cleaned from the surface to be cleaned.

Its 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 installed inside this J'1u remover body 1. 3 is the floor nozzle,
Inside thereof, a rotary bluff 4 is rotatably supported by a bearing 5, and the rotary bluff/4 is rotated by an electric rock 6 for a rotary mold and a belt 7. The dust separated from the surface to be cleaned by the rotary blower 4 passes through the suction passage 9 from the suction port 8 to the dust collection chamber 11 configured below the filter 10. It gets sucked in.

12 is a rotating brush 4 when the surface to be cleaned is like a floor or a tatami mat.
This is a clutch lever that stops the rotation plan from 40 rotations when it is not required.

However, in the above configuration, since there are two electric motors, an electric blower and a rotary brush electric motor, the weight is heavy and the cost is also high.

Furthermore, you can use the rotating brush 4 while using the vacuum cleaner! [: There was the inconvenience of having to bend down and reach for the floor nozzle in order to switch.

Purpose of the Invention In order to solve the above-mentioned drawbacks, the present invention uses a single electric motor to drive the blower and rotating brush, thereby reducing weight and cost, and changing the use of the rotation plan by operating a plan changeover switch provided on the handle. This can be done via a solenoid.

Structure of the Invention To achieve this object, the vacuum cleaner of the present invention includes a vacuum cleaner body with a built-in electric blower, a power transmission shaft for transmitting power from the electric blower to a rotating brush, and a clutch mechanism. , the clutch mechanism is changed over via a solenoid by operating a brush changeover switch provided on the handle.

! With this configuration, the electric blower can transmit power to the rotating brush on the power transmission shaft while being installed inside the vacuum cleaner body, eliminating the need for an electric motor for the rotation plan, reducing weight and cost. The rotating brush can be switched while the vacuum cleaner is in the same position as when in use, improving operability.

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

In FIGS. 3 to 5, 13 is a vacuum cleaner body, and 14 is a floor nozzle. An electric blower 15 is vertically provided on the inside upper part of the cleaner body 13, and a first shaft 1 is supported in parallel with an electric blower shaft 16 by a first bearing 1o. A driving pulley 19 and an idle pulley 20 are attached to the first shaft 17.

These constitute a clutch mechanism, which is supported by a holding plate 21 and fixed to the electric blower 15 with screws 22. In addition, this entire structure includes the front vibration isolator 23 and the rear vibration isolator 2.
Vacuum cleaner body 13K via 4! Supported.

A motor belt 25 is selectively applied to the electric blower shaft 16, drive pulley 19, and idle pulley 20 by a solenoid 26, a switching shaft 2γa, and a switching lever 27b.

One end of the first shaft 17 is connected to a power transmission shaft 28,
This power transmission shaft 28 passes through the inside of the cleaner body 13,
It is connected to an intermediate shaft 29 inside the floor nozzle 14 .

A rotating bluff 30 is rotatably mounted parallel to the intermediate shaft 29, and a rotating brush belt 32 is stretched between the intermediate shaft 29 and the rotating brush pulley 31.

The cleaner body 13 and the floor nozzle 14 are rotatably connected through a connecting pipe 33.

In addition, a filter 34 is provided inside the lower part of the vacuum cleaner body 13.
A dust collection chamber 35 is configured.

36 is a handle attached above the vacuum cleaner body 13;
A brush changeover switch 37 connected to the solenoid 26 is attached to the tip of the handle 36.

The operation of the vacuum cleaner configured as described above will be described below. The output of the electric blower 16 installed inside the hu rock removal main body 13 is output from the electric blower shaft 16. Motor belt 25. The first shaft 17 via the driving pulley 20
The power is transmitted from the power transmission shaft 28 to the power transmission shaft 28. The rotational force transmitted to the power transmission shaft 28 is transmitted from the intermediate shaft 29 inside the floor nozzle 14 to the rotating brush belt 32 and the rotating brush pulley 31.
is transmitted to the rotating brush 30 and rotated.

The dust separated from the surface to be cleaned by the rotating plan 30 is
Dust collection chamber 35 below filter 34 through connecting pipe 33
It accumulates.

In addition, in the case of JW blood removal that does not require the rotation plan 30, a plan changeover switch 37 provided on the handle 36 can be used.
′! i'', the solenoid 26 operates, this operation is magnified by the switching lever 27b, and the motor belt 25 is activated by the switching lever 27a.
The rotation of the rotating brush 30 is stopped by being replaced by the idling goo IJ20.

As described above, according to this embodiment, by transmitting power from the electric blower 15 to the rotary brush/30 using the power transmission shaft 28, the electric blower 15 is placed vertically and the vacuum cleaner main body 13 (!- The rotating brush 30 can be driven by the electric blower 15 with a configuration in which the passage from the suction port to the dust collection chamber 35 is made narrower and the pressure loss in the suction passage is reduced.

Therefore, there is no need for an electric motor to drive the rotation plan.
SF, +Cost can be reduced. Further, the use of the rotation plan 3° can be easily switched through the solenoid 26 by operating a brush changeover switch 37 provided on the handle 36.

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 return machine body to the rotating plan in the floor nozzle, so that it can be configured with a single electric motor. Therefore, weight and cost can be reduced, and by providing a brush changeover switch on the handle, switching between rotation and stop of the rotating brush can be performed in the posture during use, improving operability.
