Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vacuum cleaner for wiping, for example, the floor of a passageway in a building.

[Conventional technology]

Conventionally, when wiping a floor surface, etc., it was done manually using a mop, or using a rotating brush (so-called polyrusha) that is rotationally driven by an electric motor or the like.

[Problem to be solved by the invention]

Conventional means not only have the disadvantage of requiring a large amount of labor for wiping, but also have the risk of uneven finished product due to differences in the skill level of the workers. Further, when a rotating brush is used, not only a large driving force is required, but also there is a disadvantage that noise becomes large.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable accurate wiping while reducing the labor involved in wiping.

[Means to solve the problem]

The vacuum cleaner according to the present invention is characterized in that a cleaning roller whose outer peripheral portion has water absorbency is provided so as to rotate while keeping its outer peripheral surface in contact with a running surface, and is provided with running wheels for running. The roller is rotated so that the circumferential speed of the running wheel and the circumferential speed of the roller are different and rotated in the same direction, or the rotational direction of the running wheel and the rotational direction of the roller are different. The point is that a driving means for rotationally driving the is provided.

[For production]

If the circumferential speed of the running wheel and the roller are made different and rotated in the same direction, or if they are made to rotate in different directions, the outer circumferential surface of the roller will change to the running surface as the vacuum cleaner moves. The robot rotates while sliding against the surface of the vehicle, wiping the running surface.

〔Effect of the invention〕

Therefore, wiping can be performed accurately simply by running the vacuum cleaner along the running surface, and the labor required for wiping can be reduced while preventing unevenness in the finish.

In addition, the driving force is small because the circumferential speed of the roller and the running wheel are simply driven in the same direction with different circumferential speeds, or the roller and the running wheel are driven in different directions of rotation. Moreover, the noise caused by the rotational drive is also small.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, a cleaning roller (1) is provided, the outer circumferential surface of which is wound with a sponge-like material having water absorption properties such as PVA (polyvinyl alcohol). A pair of left and right free-rotating running wheels (2) are provided on the rear side of the vacuum cleaner 1), thereby forming a hand-held vacuum cleaner.

The roller (1) is configured to be rotationally driven by the rotational force of the running wheel (2) transmitted by a chain (3). However, the diameter of the roller (1) is smaller than the diameter of the running wheel (2),
As the vehicle travels, the rollers (1) and the traveling wheels (2) are driven to rotate at different peripheral speeds in the same direction, but at different peripheral speeds.

In other words, the running wheels (2) and the churn (3) correspond to a driving means (100) that rotationally drives the roller (1).

Further, a portion on the front side and upper side of the roller (1) is in pressure contact with the roller (1), and the roller (
1) a squeezing roller (4) that squeezes out the sewage sucked in;
A sewage receiver (5) that receives and stops the sewage squeezed out by the squeezing roller (4) and collects the sewage in the sewage receiver (5) to a sewage recovery tank (6) provided on the main body side. An electric pump (7) is provided. In addition, (8) in the figure is a handle.

However, before wiping, the floor surface is moistened with cleaning water or the like in advance, but it is also possible to run the vehicle while spraying cleaning water on the front side of the vehicle.

[Another example]

In the above embodiment, in order to drive the roller (1) and the running wheel (2) in the same direction with different circumferential speeds, the roller (1) and the running wheel (2) have different diameters. Although the example is shown, the diameter may be the same and the reduction ratio by the chain (3) may be changed. Further, the circumferential speed of the roller (1) may be larger or smaller than the circumferential speed of the running wheel (2), as long as the circumferential speed of the roller (1) and the running wheel (2) are different. .

Further, in the above embodiment, the roller (1) and the running wheel (2) are configured to have different circumferential speeds and are driven in the same direction, but they may be driven in opposite directions.

However, when driving in the opposite direction, the same speed may be used.

Further, in the above embodiment, the roller (1) is connected to the running wheel (2).
), but the rotation may be driven by, for example, an electric motor, etc. In short, as the vacuum cleaner runs, the roller (1) is It suffices that the peripheral surface be able to move while causing slippage on the running surface, and the roller (1
) can be modified in various ways.

Further, in the above embodiment, the running wheel (2) is formed as an idle wheel, but it is driven by an electric motor or the like,
The vacuum cleaner may be configured to be self-propelled, and the specific configuration of each part can be changed in various ways.

Further, in the above embodiment, the case where - number of rollers (1) are provided is illustrated, but a plurality of rollers (1) may be provided.

For example, as shown in FIG. 3, a pair of left and right running wheels (2) is provided in the center of the vehicle body (V), and a pair of running wheels (2) on both the front and rear sides of the running wheels (2) is provided with a structure similar to that of the above embodiment. A pair of front and rear rollers (la) and (lb) are provided, and the front roller (1a) is connected to an electric motor (9) and a transmission bell (1).
0), the roller (1b) on the rear side is supported in an idle rotation state, and cleaning water is applied in front of the roller (1a) on the front side of the travel. While sprinkling water, the front roller (1a) may be used for wiping, and the rear roller (1b) may be used to absorb dirty water.

In other words, the electric motor (9) and the transmission bell) (10)
corresponds to a driving means (100) for rotationally driving the roller (1a) in a direction opposite to the traveling wheel (2).

In the figure, (4a) and (4b) are the rollers (la).
