Abstract

(57) [Summary] [Purpose] In a floor cleaning machine, it corresponds to the locally persistent dirt on the floor. A floor cleaning machine comprising a spraying means of a cleaning machine, a horizontally rotating brushing means, and a wastewater waste liquid storing means, wherein the floor cleaning machine is equipped with a vibration means for swinging the brushing means to the left and right. This is a structure for locally and persistently scrubbing dirt on the floor surface in a short time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a floor cleaning machine that sprays a cleaning liquid on the floor, removes dirt on the floor by a brushing action, and stores the dirty water.

[0002]

[Prior art]

 A large number of self-propelled washing machines are known in which a cleaning liquid is sprayed on the floor surface to clean the floor surface and the waste liquid waste is sucked up by a squeegee and stored in a tank. For example, there is Japanese Patent Publication No. 43-10668.

[0003]

[Problems to be solved by the device]

 In the conventional self-propelled horizontally rotating brushing means, the floor surface becomes unstable, the spots where the dirt is dirty are stationary, or forward and backward movements are repeated to remove the dirt, resulting in poor efficiency.

[0004]

[Means for Solving the Problems]

 The present invention is configured as follows in order to solve the above problems. A floor cleaning machine comprising a cleaning liquid spraying means, a horizontally rotating brushing means, and a wastewater waste liquid storage means, comprising a vibrating means for swinging the brushing means to the left and right. It was provided.

[Action]

 Bring the floor washer of the present invention to the floor of a supermarket or the like to start the washing operation, and perform normal horizontal rotation of brushing. Then, the dirt that is locally relieved on the floor surface is vibrated to the left and right, and the vibrating means is actuated to horizontally rotate the brushing simultaneously and secondarily vibrate horizontally to drop the dirty water at a stretch and move forward.

[0006]

【Example】

 The configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 is a side view showing the present invention with a part omitted, FIG. 2 is a perspective view showing a main part, and FIG. 3 is a plan view showing an operation of the main part.

Reference numeral 2 denotes a machine frame, which has an L shape, and on which a cleaning liquid tank 9, a battery 10, a dirty water tank, a suction blower, and the like are placed in front, and which is covered with a cover body 1. 20 is a brushing means and is installed in the lower front part of the machine casing 2. Reference numeral 8 is a free wheel, and 6 is a drive wheel, which has self-propelled drive means (not shown). Reference numeral 5 is a squeegee which sucks in the waste water generated by the brushing means 20 and stores it in a waste water tank (not shown). Reference numeral 3 is an operation unit, and 4 is a handle.

Next, the brushing means 20 will be described in detail with reference to FIGS. 1 and 2. A main motor 11 drives the brush body 7 via the rotary shaft 23. A plate frame 14 is fixed around the main motor 11, and a guide frame 16 is fixed in front of and behind the machine frame 12 in parallel to the left and right direction. A sliding bar 17 is slidably provided on the guide frame 16, and support members 18, 18 'are fixed to the left and right ends of the sliding bar 17. The sub motor 12 having the cam body 13 is provided on one support member 18. The cam body 13 is arranged so as to be adhered to the side surface of the machine frame 2 described above. Reference numeral 22 denotes a coil spring mounted on the sliding frame 17 on the opposite side of the sub motor 12, and always supports the main motor 11. The cam body 13 is elastically attached to the side surface of the plate frame 14.

Reference numeral 19 is a part of the frame frame 19 forming the machine frame 2, and supports the support member 18 described above on a supporting page (3). Reference numeral 15 denotes a liquid supply hose, the tip of which is located inside the brush body 7 and is connected to the cleaning liquid tank 9 described above.

Reference numeral 21 denotes an elevating bar, which depresses an end pedal projecting downward of the operation portion 3 to switch the brushing portion between a working state and an upper position during movement.

FIG. 3 is a plan view showing the action of the brushing portion. When the sub motor 12 rotates with the traveling direction downward, the cam body 13 rotates to press and rotate the side surface of the plate frame 14. At this time, the guide frame 16 of the plate frame 14 supporting the main motor 11 with respect to the supporting member 18 to which the sub motor 12 is fixed is vibrated in the left-right direction (f) with respect to the sliding rod 17.

[0012]

【effect】

 With the above-mentioned configuration, in addition to the conventional normal cleaning work, for locally persistent stains, horizontal rotation brushing can be applied to add secondary vibration to the left and right to clean immediately. As a result, the number of repetitive forward / backward movements has decreased and work efficiency has improved significantly.
