The present invention relates to a vacuum cleaner, and more particularly, to a motorized cleaning device configured to drive a cleaning tool such as a rotary brush as an electric motor.

In general, the electric sweeper is composed of a disk-shaped cleaning tool (B) rotated about an axis in the vertical direction with respect to the floor as shown in Figure 1a, b and a drive motor (Ma) for driving it, the disk-shaped The sweeping tool (B) is mainly in the form of a brush, and one or more are provided according to the type.

As shown in (a), in the case of a single type electric sweeper having only one cleaning tool (B), a torque that the body itself rotates in one direction by friction force induced between the cleaning tool (B) and the bottom surface, that is, In addition, there is a disadvantage that is very difficult to work because it has a rotational deflection force, in particular, if the cleaning machine is in close contact with the floor surface and its rotation axis is not perpendicular to the floor surface, it becomes more unstable due to the imbalance of the force, the body of the cleaner body is one-way There is a problem that is pushed sharply.

Therefore, it is a very heavy burden for the operator to control this, and even in this simple cleaning machine, skill is required.

Some of the sweepers developed to solve these problems have a pair of the above-described disk-shaped sweepers (B) and (B), as shown in FIG. 1B, which is used to offset the deflection force to one side. (B) is configured to rotate in opposite directions to each other. Such a sweeper has a more stable surface than the above-described sweeper, but this also causes a problem that a rotational bias force to be biased to one side is still generated unless the two sweepers B are positioned to have a uniform grounding force. In addition, even if the deflection force is not generated to one side, the driving force in one direction is obtained by the rotation of the two cleaning tools in the opposite direction. In this case, there is a hassle for the worker to hold the cleaner.

The present invention is devised to improve the above problems, the stability of the operation is improved, the workability is greatly improved, and the purpose of providing a high-quality electric cleaning machine with a greatly improved cleaning efficiency.

In order to achieve the above object, the present invention is provided with two disk-type sweepers which rotate about a rotation axis in the vertical direction with respect to the floor to be cleaned, and a drive motor which is a driving body thereof, which is parallel to the floor. The roller-type cleaning tool rotated about a horizontal axis is installed in parallel with the arrangement direction of the said disk-shaped cleaning tool.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

This embodiment is well illustrated in FIG. 2, which includes a drive motor Mb and a water tank T located at the top of the cover CV, and a roller-type cleaning tool B2 located at the bottom of the cover CV. ) And disc shaped tools (B1), (B1), and connected to a tubular nozzle (N) installed in a skirt (SK) provided in front of the cover (CV), which nozzle (N) is a skirt (SK). It is installed in the longitudinal direction so that water can be supplied to the bottom roller-type cleaning tool B2.

And the above-mentioned cleaning tool (B1), (B2) can have the form of a strong brush of the most common form, and in some cases can be formed of a soft face material, it can also be used to combine and merge them in combination, Although idiomatic, it should be possible to remove it from the individual power elements.

Meanwhile, referring to the power transmission system of the present invention, as shown in FIG. 2 and FIG. 3, the roller-type cleaning tool B2 and the two disk-shaped cleaning tools B1 arranged in parallel with each other are one driving motor ( It is connected by means of a gear group so as to be rotated by Mb).

That is, the drive gear G1 of the drive motor Hb is directly connected to the driven gear G3 of the disc-shaped cleaning tool B1 on the left side of the drawing, and is driven from the driven gear G3 of the disc-shaped cleaning tool B1 on the right side. Indirect connection through planetary gear (G2).

The planetary gear G2 is coaxially connected to the lower driving side bevel gear G5, and the driving shaft bevel gear G5 is connected to the driven fleece P2 of the roller-type cleaning tool B2 by a belt. It is meshed with the driving pulley P1 and the coaxial driven bevel gear G5. In the figure, reference numeral BP denotes a base plate, and PH denotes a poly housing.

The present invention of the configuration as described above is to drive the two disk-shaped cleaning tool (B1), (B1) and one roller-type cleaning device (B2) at the same time by one drive motor (Hb), wherein the roller Stabilization effect by the mold material B2 can be expected.

That is, it has a stable three-point support structure through the two disk-shaped tools (B1), (B1) and one roller-type cleaning tool (B2), in particular the roller-type cleaning tool (B2) Since the ground is long in the arrangement direction of the spheres B1 and B1, the inclination to the disc-shaped cleaning sphere B1 on one side is prevented.

Furthermore, the disc-shaped cleaning tools (B1), (B1) are positioned on the bottom surface and have a one-way traveling force even if they do not have a rotational deflection force in one direction. As shown in FIG. 5, the roller-type cleaning tool B2 is rotated to cancel each other. As a result, the entire cleaning machine is located in a stable position in a fixed position, and the cleaning efficiency is excellent for the worker, and of course, it is very convenient for use. In addition, it is possible to supply water through the roller-type cleaning tool (B2) to the bottom surface when cleaning, thereby maximizing the cleaning efficiency of the bottom surface.

As described above, the present invention is configured to operate very stably with high cleaning efficiency during cleaning work, so that the cleaning work can be performed very easily and the large area cleaning within a short time through the disk cleaning roller and roller cleaning equipment Is made possible.
