Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention is a floor cleaning machine that cleans floors with carpets and tiles using a cleaning solution. Concerned.

[0002]

[Prior art]

  FIG. 6 is an external perspective view showing the structure of a conventional floor cleaning machine. In the figure, 1 is internal A cleaning liquid tank 2 containing a cleaning liquid and a waste water recovery tank 3 for collecting the recovered waste water The floor cleaning machine main body 4 in which the above are housed side by side is a ceiling cover for opening and closing the upper opening of the main body. A plate 5 is a manual attached to the rear surface with respect to the traveling direction of the floor cleaning machine body 1. 6 is a handle for moving the lever, 6 is located on the bottom surface of the main body 1 and has two rotating brushes 71, 72 The rotating brush which is rotatably provided and which is provided from the cleaning liquid tank 2 through a pipe 8. The cleaning liquid is supplied to each of 71 and 72, and it is possible to freely rotate around the pipe 8 itself. The cleaning means 9 is a moving wheel that serves as a guide when the main body is moved, and 10 is a bottom surface of the main body. A squeegee, 11 provided as a sewage recovery means provided at the rear of the traveling direction is the squeegee. A pipe for carrying the wastewater collected from the squeegee 10 to the recovery tank 3, and 12 is the squeeze When the squeegee 10 is rotatably provided at both ends of the gage 10, and the squeegee 10 contacts a wall surface or an obstacle. Wheel for alleviating the shock of the body and facilitating movement of the body 1 after contact Is.

[0003]   In the above structure, the relationship between the cleaning means 6 and the squeegee 10 is FF (front engine). The front and rear wheels of a car are similar to the relationship between the front and rear wheels in the curve track. Due to the difference in the inner ring, there is a part where the sewage produced during cleaning cannot be collected. There was a problem.

[0004]   Further, the squeegee 10 has a higher suction force at the central portion than at both ends, and the movement locus of the main body 1 Sewage is collected well in the central part of the sewage, but sewage cannot be collected and remains at the ends. There was also a problem.

[0005]

[Problems to be solved by the device]

  The present invention has been made in view of the above-mentioned problems of the prior art. It is an object of the present invention to provide a floor washing machine that can efficiently collect the floor.

[0006]

[Means for Solving the Problems]

  The present invention provides a moving wheel for moving on a floor, a cleaning means for cleaning the floor, and Cleaning liquid supply means for supplying the cleaning liquid to the cleaning means, and a collecting hand for collecting the dirty water after cleaning In a floor cleaning machine having a step, the collecting means faces in the traveling direction of the floor cleaning machine. And a gathering portion gathered in a narrow portion of the swinging portion which spreads wider than the width of the cleaning means. It is composed of a suction unit that sucks up the collected dirty water.

[0007]   And it is desirable that the recovery means is arranged between the cleaning means and the driving wheel. Good

[0008]

[Action]

  The floor is washed by the washing means, and the generated wastewater is collected by the sewage unit of the collecting means. They are collected in the central part of the means and sucked up at once from the suction part.

[0009]   If there is a recovery means near the cleaning means, the trajectory of the cleaning means and the trajectory of the recovery means. The difference from the trace is small, and the part that cannot be recovered is reduced.

[0010]

【Example】

  Hereinafter, the floor cleaning machine of the present invention will be described in detail with reference to the drawings. The appearance and basic Since the configuration is the same as the conventional one, the description is omitted and the same components as those of the conventional one are omitted. One code is given and shown.

[0011]   FIG. 1 is a bottom view of the essential part of the floor cleaning machine of the present invention, where 1 is the floor cleaning machine main body and 71 and 72 are cleaning. Rotary brush, 9, 9 are driving wheels, 91, 92 are motors for driving the driving wheels 9, 10 are Immediately behind the rotary brushes 71, 72 with respect to the moving direction of the floor cleaner (indicated by arrow A). It is a squeegee as a sewage recovery means located.

[0012]   The squeegee 10 includes a suction portion 101 which is orthogonal to the moving direction A, and the suction portion 1 It has rubber shafts 102 and 103 expanded from 01 in the moving direction A. Also As shown in the perspective view of the main part of the squeegee 10 in FIG. Has become.

[0013]   Further, at the front end of the main body 1 in the moving direction A, the cleaning liquid is rotated by the rotation of the brushes 71, 72. A cover 13 is provided to prevent scattering.

[0014]   The operation of the above structure is shown in the sectional view of the squeegee 10 in FIG. 3 and the squeegee in FIG. 10 will be described with reference to a plan view and a plan view showing a moving state of the floor cleaning machine main body 1 in FIG. .

[0015]   As shown in FIG. 3, the suction portion 101 of the squeegee 10 has a gap 1 on the front side in the moving direction A. The rear side is closely attached to the floor so that sewage in the front is easily taken in and escaped. It is a structure that is difficult to do. Therefore, as shown in FIG. The collected sewage moves to the center of the suction unit 101, and near the decompression port 104 with the strongest suction force. Since it is sucked by the side, the collection capacity is improved.

[0016]   In FIG. 5, the floor cleaning machine main body 1 at the position a is rotated about the rotation center O and Assume the case of moving to the position. In this case, the loci drawn by the brushes 71 and 72 are solid in the figure. A squeegee located at the rear end of the main body 1 becomes a circular arc shown by the lines C and D as in the conventional case. In the case of 10, draw an arc outside the loci C and D as shown by broken lines E and F in the figure. Therefore, the sewage in the area shown by the shaded area in the figure is not collected. On the other hand, In the present embodiment in which the jig 10 is immediately behind the brushes 71 and 72, the gauge drawn by the squeegee 10 is used. The traces are almost the same as the traces c and d drawn by the brushes 71 and 72, and the dirty water in the area It can be collected efficiently.

[0017]   In FIG. 5, reference numeral 14 is a universal caster provided to facilitate rotation of the main body 1. Is.

[0018]

[Effect of device]

  The present invention provides a moving wheel for moving on a floor, a cleaning means for cleaning the floor, and Cleaning liquid supply means for supplying the cleaning liquid to the cleaning means, and a collecting hand for collecting the dirty water after cleaning In a floor cleaning machine having a step, the collecting means faces in the traveling direction of the floor cleaning machine. And a gathering portion gathered in a narrow portion of the swinging portion which spreads wider than the width of the cleaning means. Since it consists of a suction unit that sucks up the collected sewage, it has a strong suction force. It is possible to suck up and improve suction efficiency.

[0019]   Further, by installing the recovery means between the cleaning means and the moving wheel, the cleaning means can be moved. The movement locus and the movement locus of the collection means can be made to be almost the same, and the wastewater can be collected and left uncollected. It is possible to keep the number of creases small and always collect on the floor where moving wheels move. Since the sewage is collected by the means, slippage can be suppressed and the position of the washing machine The effect that control etc. can be surely produced.
