BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool, and more particularly to a floor deposit remover for easily removing deposits such as gums and tapes attached to the floor such as sidewalks and station yard.

[0002]

2. Description of the Related Art In cleaning work, there is a work for removing gums, tapes, etc. adhering to the floor surface, and there is a work for separating the adhering material from the floor surface and accommodating the separated adhering material. As a cleaning tool that removes adhered substances from the floor surface, it is actually used as a cleaning tool 59-7066.
The flat thin plate-shaped blade disclosed in No. 4 has been used in the old state, but the work of bending down is a work that puts a strain on the waist and makes the work crying, and it is also aesthetically unsatisfactory recently. , An electric gum removing machine (EGS10 shown in FIG.
0) has been commercialized by Oppama Industrial Co., Ltd. and is being tried in JR West Japan. This gum removing machine (EGS100) has a main body 51 with a built-in rechargeable battery (nickel cadmium battery) and a DC magnet motor, and is replaceably attached to the front end of the main body 51 and vibrates finely (stroke width 0.7 mm every The blade 52 vibrates 3800 times) and the rod body 53 with a handle attached to the rear end of the main body 51. The main handle 53a is placed on the rod body 53 at a position suitable for performing gum removal work while standing.
And a sub handle 53b are attached, and the start switch 5 is attached to the main handle 53b so that the main switch 54 and the cutting edge 52 are reversed and used.
5 are provided above and below. In JR West Japan, which wipes this gum removing machine, it can be taken quickly and is lightweight (about 2.5 kg).
It is said that it started to be used at 94 stations in Kinki because it is well received by workers because it can turn around quickly.

[0003]

The gum removing operation using the above gum removing machine is certainly easier than the operation using the conventional metal spatula, but the adhered gum is forcibly scraped off by mechanical vibration. However, the work posture seemed to be using a rock drill, and it was seriously unsuitable for female workers. Therefore, it is desired to provide a smart gum removing machine that can be easily used by a female worker, and the present invention is to solve this problem.

The floor adhered matter removing machine provided with a container for
According to a fifth aspect of the invention, in the first or second aspect of the invention, a floor surface adhered matter removing machine is provided in which the outer surface of the scraper is subjected to a non-adhesive treatment.

[0005]

According to the first aspect of the present invention, a refrigerant is sprayed onto the adhered substance clinging to the floor surface to cure the adhered substance, reduce the adhesive force of the adhered substance to the floor surface, and then remove the adhered substance with a scraper. As a result, it becomes a floor deposit removing machine that can be easily used by female workers. Even if the scraper is a manual type, it is easy to remove the deposits quickly. or,
According to the second aspect of the present invention, the scraper that removes adhered substances clinging to the floor surface is driven forward and backward reciprocally with an electric force at a gentle inclination (generally parallel) with respect to the floor surface in the standard working state.
The scraper becomes wedge-shaped between the deposit and the floor surface, and the deposit can be taken easily and quickly. According to the third aspect of the present invention, by adding a wheel that holds the removing machine in the standard working state with the scraper and movably configures the removing machine, it is not necessary for the worker to hold the removing machine in the standard working state. Work posture is very easy. Workers can use the wheels to move the remover so that the scraper is in front of the deposits, put their hands on the handle of the remover, operate various switches, and remove the deposits using the wheels. it can. According to the fourth aspect of the present invention, by providing the rotating brush that is rotationally driven by rotation to scrape up the aesthetics on the floor surface, and by providing the container for storing the aesthetics scraped by the rotating brush behind the rotary brush. The detached adhered matter can be cleaned by moving the remover forward and backward, and a single removing machine can perform a consistent operation from the detachment of the adhered matter to the cleaning. According to the fifth aspect of the present invention, by applying a non-adhesive treatment to the outer surface of the scraper, it is possible to prevent the adhered matter from adhering to the scraper and reduce the maintenance frequency of the scraper.
