Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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 Vacuum cleaners are known that are equipped with a rotating brush that separates dust attached to a surface to be cleaned from a surface to be cleaned.

The structure will be explained based on FIG. 1. In the figure, 1 is a vacuum cleaner main body, and an electric blower 2
03 is a floor nozzle in which a rotary brush 4 is rotatably supported by a bearing 6. The rotary brush 4 is rotated by a rotary brush electric motor 6 and a belt 7. The dust separated from the surface to be cleaned by the rotating brush 4 passes through the suction passage 9 from the suction port 8 to the filter 1.
The dust is sucked into the dust collection chamber 11 configured below the angle.

However, in the above configuration, since there are two electric motors, an electric blower and a rotating brush motor, the weight becomes heavy and the cost increases. Another drawback is that the floor nozzle becomes large because it accommodates the electric motor for the rotating brush.

There are also existing vacuum cleaners that have an electric blower installed at the bottom of the vacuum cleaner body and drive a rotating brush with the electric blower, but the suction port is connected to the dust collection chamber with a hose, and the distance is long and there is a loss. However, since the electric blower is placed horizontally, the width of the main body is large.

Purpose of the Invention In view of the above drawbacks, the present invention reduces weight and cost by driving the blower and rotating brush with one electric motor, shortens the suction distance to reduce loss, and makes the floor nozzle part detachable. To provide a vacuum cleaner that can be replaced with a floor nozzle suitable for the surface to be cleaned. Structure of the Invention To achieve this object, the vacuum cleaner of the present invention uses an electric blower or a rotating brush. A coupling is provided at the connection part of the power transmission shaft that transmits power between the vacuum cleaner body and the floor nozzle,
The vacuum cleaner body and floor nozzle are detachable.

With this configuration, power can be transmitted from the electric blower to the rotating brush while the electric blower is installed vertically in the upper part of the vacuum cleaner body, eliminating the need for an electric motor for the rotating brush, reducing weight and cost, and reducing overall vacuum cleaner efficiency. 〇 Also, since the power transmission shaft is equipped with a coupling, it can be replaced with a floor nozzle suitable for the surface to be cleaned □ Description of the Embodiment Please refer to the drawings below for an embodiment of the present invention. 〇 Figure 2 shows a vacuum cleaner according to an embodiment of the present invention, Figure 3 shows the connection part on the main body side, and Figure 4 shows the connection part on the floor nozzle side. . In FIGS. 2 to 4, 12 is a vacuum cleaner body, and 13 is a floor nozzle.

An electric blower 14 is installed vertically in the upper part of the vacuum cleaner body 12, and a first shaft 16 is connected to the first bearing 1 in parallel with the electric blower shaft 15.
It is pivoted by 7. A first belt 20 is attached to the electric blower pulley 18 attached to the electric blower shaft 15 and the first shaft boolean IJ+19 attached to the first shaft 16.
is being passed around.

A power transmission shaft 21 such as a flexible wire on the main body side is attached to one end of the first shaft 16, and this power transmission shaft 21 is attached to the bottom of the vacuum cleaner main body 12, and the main body is pivotally supported by a coupling bearing 22 on the main body side. It is connected to the side coupling 23.

A rotating brush 24 is provided inside the floor nozzle 13,
A second shaft 25 is supported by a second bearing 26 in parallel with this. A second belt 29 is passed around a rotating brush pulley 27 attached to the rotating brush 24 and a second shaft pulley 28 attached to the second shaft 26 .

A power transmission shaft 30 such as a flexible wire on the floor nozzle side is attached to the other end of the second shaft 25, and this power transmission shaft 30 is connected to the cleaner body 12 by a coupling bearing 31 on the floor nozzle side. It is connected to the pivoted cup 1 hook 32 on the floor nozzle side, and the coupling 32 on the floor nozzle side and the coupling 23 on the main body side connect the vacuum cleaner main body connection pipe 33 and the floor nozzle connection pipe 34. When connected.

A filter 35 is still provided inside the cleaner body 12, and a dust collection chamber 36 is configured below it.

The operation of the vacuum cleaner configured as described above will be described below.

The output of the electric blower 14 installed inside the vacuum cleaner body 12 is
Power is transmitted from the electric blower shaft 15 via the electric blower pulley 18, the first belt 20, and the first shaft pulley 19, and from the first shaft 16 to the power transmission shaft 21 on the main body side. Further, the power transmitted to the power transmission shaft 21 is transmitted to the power transmission shaft 3o on the floor nozzle side via the coupling 23 on the first main body side and the coupling 32 on the floor nozzle side, and the power is transmitted to the power transmission shaft 3o on the floor nozzle side.
The rotating brush 24 is rotationally driven through the second shaft pulley 28, the second belt 29, and the rotating brush pulley 27.

The dust separated from the surface to be cleaned by the rotating brush 24 is transferred to the floor nozzle connection pipe 34 and the vacuum cleaner main body connection pipe 33.
A dust collection chamber 36 configured below the filter 35 through the
Nita-1 varnish □ As described above, according to this embodiment, power transmission 11Qb21
．． By providing 30 and coupling 23.32,
Power can be transmitted to the rotating brush from the electric blower installed vertically in the upper part of the vacuum cleaner body, eliminating the need for an electric motor to drive the rotating brush, shortening the distance from the suction port to the dust collection chamber, and reducing weight and loss. In addition to being able to reduce costs, the vacuum cleaner main body and the floor nozzle can be attached and detached by the couplings 23 and 32, and when cleaning gaps, the gap nozzle can be replaced, or the floor nozzle can be replaced with a floor nozzle suitable for the surface to be cleaned.

Effects of the Invention As described above, the vacuum cleaner of the present invention transmits power from the electric blower to the rotating brush using a power transmission shaft, and a cup is attached to the connection part of the power transmission shaft between the vacuum cleaner body and the floor nozzle. By providing a ring, the electric blower can be placed vertically, making the vacuum cleaner body thinner, shortening the distance from the suction port to the dust collection chamber, and driving the rotating brush with the electric blower. This eliminates the need for an electric motor to drive the rotating brush, reducing weight and cost.
Since the floor nozzle and the cleaner body are removable, the floor nozzle can be replaced with a floor nozzle suitable for the surface to be cleaned.
