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. Use this to communicate the following:

2. Description of the Related Art Conventional Structures and Problems There have been conventionally known vacuum 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 the vacuum cleaner main body 1. Reference numeral 3 designates a floor nozzle, inside which a rotary brush 4 is rotatably mounted by a bearing 6, and a rotary brush 4 is rotated by a rotary bluff electric motor 6 and a belt 7. Dust separated from the surface to be cleaned by the rotating brush 4 passes through the suction passage 9 from the suction port 8 and is sucked into the dust collection chamber 11 configured below the filter 10.

Reference numeral 12 denotes a clutch lever that stops the rotation of the rotary brush 4 when the surface to be cleaned does not require the rotary 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 rotary brush electric motor, the weight is heavy and the cost is also high. In addition, since the electric motor for the rotating brush is housed, the floor nozzle has the disadvantage of becoming harsh.

Purpose of the Invention In order to solve the above-mentioned drawbacks, the present invention aims to reduce the weight and cost by driving the blower and the rotation plan with two motors, and to reduce the size of the nozzle. Vibration of the power transmission shaft that transmits power to the rotating brush,
The purpose is to prevent noise.

Groove Bottom of the Invention The present invention transmits the rotational force of an electric blower to a rotating brush via a power transmission shaft, and the power transmission shaft is attached to the vacuum cleaner body via vibration isolating rubber, reducing weight and cost. In addition to reducing the size of the floor nozzle, the vibration of the power transmission shaft has also been reduced.

This is to prevent noise.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying 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 at the inner lower part of the cleaner body 13 , and a first shaft 18 provided parallel to the electric blower shaft 16 is supported by a first bearing 17 .

The first shaft 17 includes a drive pulley 19 and an idle boob IJ-
20 is attached.

These clutch and chi mechanism parts are supported by a mounting plate 21 and fixed to the electric blower PA1s with screws 22.

Further, this entire body is supported by the cleaner main body 13 via a front vibration isolator 23 and a rear vibration isolator 24.

Electric blower shaft 16, drive pulley 19, and idle boob IJ
-20, a motor belt 25 is selectively applied by a switching lever 26 and a switching shaft 27.

One end of the first shaft 17 is connected to a power transmission shaft 28 made of a flexible wire or the like, and this power transmission shaft 28 passes through the inside of the cleaner body 13 and is connected to an intermediate shaft 29 inside the floor nozzle 14. There is.

Anti-vibration rubber 30 is wrapped around the outer periphery of the power transmission shaft 28.
, m-kake. 28°. It is installed in such a way that no signal is transmitted to the main body 13 of the aircraft.

A rotating brush 31 is rotatably mounted parallel to the intermediate shaft 29, and a rotating brush belt 33 is stretched between the intermediate shaft 29 and the rotating brush pulley 32.

The cleaner body 13 and the floor nozzle 14 are rotatably connected through a connecting pipe 34.

In addition, a filter 35 is provided inside the lower part of the vacuum cleaner body 13.
A dust collection chamber 36 with a dust collection chamber 36 installed therein is provided with a groove bottom.

The operation of the vacuum cleaner with the groove bottomed as described above will be explained below.

The output of the electric blower 15 installed inside the vacuum cleaner body 1 is transmitted from the first shaft 17 via the electric blower shaft 16, motor belt 25, and drive pulley 19 to power transmission 4! [1128
transmitted to. The rotational force transmitted to the power transmission shaft 28 is
It is transmitted from the intermediate shaft 29 inside the floor nozzle 14 to the rotating brush 31 via the rotating brush belt 33 and the rotating brush pulley 32, and is rotated.

The dust separated from the surface to be cleaned by the rotating brush 31 is
The dust passes through the floor nozzle connection pipe 34 and accumulates in the dust collection chamber 36 below the filter 35.

When the surface to be cleaned does not require a rotating brush 31, the switching shaft 26 pushes down the motor belt 25 and replaces it with the idling pulley 20 by switching the switching lever 27 on the top of the cleaner body 1.

As described above, according to this embodiment, the power transmission shaft 28f is used to transmit power from the electric blower 15 to the rotary brush/31, and the electric blower shaft is placed vertically to make the vacuum cleaner main body 13 thinner. However, by shortening the path from the suction port to the dust collection chamber 36 housing, the rotary blower 31 can be driven by the electric blower 15 at the bottom of the groove where the pressure loss of the suction path is reduced. Therefore, an electric motor for driving the rotary plan is unnecessary, and the weight: 1'
L and cost can be reduced, and the floor nozzle can be made smaller.

In addition, the power transmission shaft 28 is vibration-proofed by the vibration-isolating rubber 3o and is mounted so that vibrations are not transmitted to the cleaner body 13, so that a vacuum cleaner with less noise and vibration can be provided.

Effects of the Invention As described above, the vacuum cleaner of the present invention has a
Power transmission from % & to the rotating bra in the floor nozzle/1. Since this is carried out using the B force transmission shaft, only one electric motor is required, reducing weight and cost, and making the floor nozzle more compact. 1. The power transmission shaft is anti-vibration with anti-vibration rubber, so we can provide a vacuum cleaner with less rustling and vibration.
