[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor cleaning machine for cleaning a floor on which carpets and tiles are stuck with a cleaning liquid.

[0002]

2. Description of the Related Art FIG. 6 is an external perspective view showing the structure of a conventional floor washer. In FIG. 1, reference numeral 1 denotes a floor washer body in which a cleaning liquid tank 2 containing a cleaning liquid therein and a sewage recovery tank 3 for storing collected sewage are arranged side by side. The plate 5 has a handle for manual movement operation attached to the rear surface of the floor washer body 1 in the traveling direction, and the numeral 6 is located on the bottom surface of the body 1.
Rotating brushes 71 and 72 are rotatable, and the rotating brushes 71 and 72
The cleaning liquid is supplied to each of the cleaning means, and is itself capable of rotating about the pipe 8 itself. Reference numeral 9 denotes a driving wheel serving as a guide when the main body moves, and reference numeral 10 denotes a traveling direction of the bottom surface of the main body. Squeeze as a wastewater recovery means provided at the rear
Reference numeral 11 denotes a pipe for carrying the wastewater recovered from the squeegee 10 to the recovery tank 3, and reference numeral 12 denotes a rotatably provided at both ends of the squeegee 10 so that the squeegee 10 comes into contact with a wall surface or an obstacle. It is an auxiliary wheel for alleviating the shock at the time of making and facilitating the movement of the main body 1 after the contact.

In the above arrangement, the cleaning means 6 and the squeegee
The relationship with 10 is that, in the same way as the relationship between the front and rear wheels of an FF (Front Engine / Front Drive) type vehicle, there is a portion on the curve track where it is impossible to collect sewage generated when washing due to the difference between the inner wheels. There was a problem.

Further, the squeegee 10 has a higher suction force at the center than at both ends, so that the sewage can be collected well at the center of the movement locus of the main body 1 but remains at the end without being collected. There were also problems.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a floor washer capable of efficiently collecting wastewater after washing. It is.

[0006]

SUMMARY OF THE INVENTION A floor washer of the present invention includes a driving wheel for moving on a floor, a cleaning means for cleaning a floor, a cleaning liquid supply means for supplying a cleaning liquid to the cleaning means, and a cleaning liquid. A collecting means for collecting the wastewater afterward, wherein the collecting means expands in the traveling direction of the floor washer, the width of the wide portion is larger than the width of the cleaning means, and the spatula; And a suction unit for sucking up sewage collected in the narrow part of the part.

[0007] Preferably, the collecting means is disposed between the cleaning means and the driving wheel.

[0008]

The floor is washed by the washing means, and the generated sewage is gathered at the center of the collecting means by the spatula of the collecting means, and is sucked up at once from the suction part.

If there is a collecting means near the cleaning means, the difference between the trajectory of the cleaning means and the trajectory of the collecting means is small,
The parts that cannot be collected are reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a floor washer according to the present invention. Since the appearance and the basic configuration are the same as those of the related art, the description is omitted, and the same components as those of the related art are denoted by the same reference numerals.

FIG. 1 is a bottom view of a main part of the floor washer of the present invention, 1 is a floor washer body, 71 and 72 are rotating brushes for washing,
Reference numerals 9 and 9 denote driving wheels, and 91 and 92 denote motors for driving the driving wheels 9 and 9.
Numeral 10 denotes a squeegee as sewage recovery means located immediately behind the rotary brushes 71, 72 in the direction of movement of the floor washer (indicated by arrow A).

The squeegee 10 has a suction portion 101 orthogonal to the moving direction A, and rubber spatula portions 102 and 103 expanded from the suction portion 101 toward the moving direction A.
Further, as shown in the perspective view of the main part of the squeegee 10 in FIG.

Further, a cover 13 is provided at the front end of the main body 1 in the moving direction A to prevent the washing liquid from scattering due to the rotation of the brushes 71 and 72.

FIG. 3 is a sectional view of the squeegee 10, FIG. 4 is a plan view of the squeegee 10, and FIG.
Will be described with reference to a plan view showing the moving state of the floor washer body 1 of FIG.

As shown in FIG. 3, the suction portion 101 of the squeegee 10 has a gap 14 on the front side in the moving direction A, and the rear side is in close contact with the floor, so that the front sewage is easily taken in. It has a structure that is difficult to escape. Therefore, as shown in FIG.
It moves to the central part of 1 and is sucked in the vicinity of the decompression port 104 having the strongest suction force, so that the collecting ability is improved.

In FIG. 5, it is assumed that the floor washer body 1 at the position a is rotated around the rotation center O and moves to the position B. In this case, the trajectories drawn by the brushes 71 and 72 are arcs shown by solid lines c and d in the figure, and in the case of the squeegee 10 located at the rear end of the main body 1 as in the prior art, as shown by broken lines e and f in the figure. Since an arc outside the trajectories c and d is drawn, sewage in an area indicated by oblique lines in the figure is not collected. On the other hand, in the case of the present embodiment in which the squeegee 10 is located immediately behind the brushes 71 and 72, the trajectory drawn by the squeegee 10 is almost the same as the trajectories c and d drawn by the brushes 71 and 72, and the area Part of the wastewater can also be collected efficiently.

In FIG. 5, reference numeral 14 denotes a universal caster provided to facilitate rotation of the main body 1.

[0018]

As described above, according to the present invention, by making the width of the wide portion of the spatula larger than the width of the washing means, it is possible to minimize the leakage of sewage collected around the washing means. Further, by collecting the sewage in the narrow portion of the spatula, the sewage can be sucked up in the vicinity of the decompression port having a strong suction power, so that the absorption efficiency is improved.

Further, by providing the recovery means between the cleaning means and the driving wheel, the movement trajectory of the cleaning means and the movement trajectory of the recovery means can be made substantially the same trajectory, and the recovery of the sewage generated by the difference between the inner rings remains. Part can be kept small, and since the wastewater is always collected by the collecting means on the floor where the driving wheel moves, slippage can be suppressed,
Position control of the washing machine can be reliably performed.
