Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device for cleaning surfaces to be cleaned, such as floors and walls, by scraping or polishing them using a cleaning disk.

[Prior Art] As a conventional device for cleaning a floor surface, for example, a sander device is known. This sander device is held in the hands of a worker, and a disk sandpaper is rotated by a drive unit and pressed against a surface such as a floor to scrape off mackerel and the like floating on the surface.

[Problems to be Solved by the Invention] However, with such conventional sanders, a worker can only operate one sander device, which limits the improvement of work efficiency and reduces work efficiency. Since the worker had to hold the sander device directly in his/her hand during the work, the working position was uncomfortable and resulted in heavy labor.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned conventional problems, and includes a rotary body on which a cleaning disk for cleaning a surface to be cleaned such as a floor surface is removably attached. The cleaning device is characterized in that a cleaning device main body having a driving section for driving the rotating body is movably supported on a base member via an elastic body, and an operating section is provided on the base member.

Further, the base member may have a box shape with the cleaning surface side open, the cleaning machine body may be disposed within the base member, and an exhaust pipe for sucking dust into a suction device may be connected to the base member. can.

Furthermore, it is also possible to arrange a suction port body around the rotating body and connect the suction port body to a suction device via an exhaust pipe.

[Function] According to this means, since the cleaning machine main body is supported by the base member via the elastic body, when cleaning the cleaning surface by holding the operation part of the base member, there will be no unevenness on this surface. Even if there is a problem, the rotating body can follow the uneven shape and change its direction, making it possible to perform a good cleaning job.

Therefore, there is no need for the worker to directly hold the keren machine body as in the past, and multiple keren machine bodies can be installed on the base member, improving work efficiency. be able to. In addition, since there is no need to hold the machine body directly, the operating section can be extended and remote control can be performed from a standing position. It can also be used as an attachment, making it easy to clean walls.

Moreover, if the base member is shaped like a box and an exhaust pipe is connected, the dust generated during cleaning work will be less likely to leak outside the base member, and the dust can be sucked into the suction device via the exhaust pipe, making the work hygienic. It can be done. In addition, by covering the rotating body with the base member,
Safety will also be ensured.

Furthermore, by disposing a suction port body around the rotating body and connecting the suction port body to a suction device via an exhaust pipe, dust can be efficiently sucked with a small suction force [Example] Hereinafter, this invention will be explained based on each example.
