In addition, terms such as "...unit" and "module" described in the specification mean a unit that processes at least one function or operation. In addition, in the drawings, the size of the components may be exaggerated or reduced for convenience of description. For example, since the size and thickness of each component shown in the drawings are arbitrarily indicated for convenience of description, the present invention is not necessarily limited to the illustrated bar.

1 is a perspective view of a window paint stain removal device according to the present invention, FIG. 2 is a bottom perspective view of the window paint stain removal device of FIG. 1, and FIG. 3 is both ends of the bottom surface of the closed curved scraper and honeycomb scraper of FIGS. 1 and 2 It is a view for explaining the right-angled corners and the noise blocking protrusion formed along the.

As shown, the window paint stain removal device according to the present invention includes a plate body 10 having a flat bottom; an edge scraper 20 having a flat bottom surface as formed to protrude downward along the bottom edge of the plate body 10; A plurality of honeycomb scrapers 30 that are formed to protrude downward from the bottom of the plate body 10 inside the edge scraper 20 and have a flat bottom surface; It characterized in that it includes; a handle 40 formed on the upper end of the plate body (10).

The edge scraper 20 and the plurality of honeycomb scrapers 30 form a closed curved surface and are extrusion-molded together with the plate body 10 . The edge scraper 20 and the honeycomb scraper 30 have a thickness of 0.5 to 2.5 mm, preferably a thickness of 1 to 2 mm.

The edge scraper 20 forms a rectangular shape, so that the edge corners 21 are formed at right angles to the four corners. By adopting the edge corner 21, the edge scraper 20 can remove the paint contaminants P contaminating the corner side of the glass window (G).

The honeycomb scraper 30 is formed inside the edge scraper 20, and is formed in the form of a circle, a hexagon, an octagon, etc. which are arranged independently of each other.

The bottom surfaces of the edge scraper 20 and the plurality of honeycomb scrapers 30 are positioned on the same plane so as to be in close contact with the surface of the glass window G at the same time, and on both sides of the bottom surface are at right angles as shown in FIG. 3 . Corners 20a and 30a are formed.

The edge scraper 20 and the plurality of honeycomb scrapers 30 are made of a soft PP material with a lower hardness than glass so as not to leave scratches or scratches on the window G in the process of removing the paint contamination applied to the window G. becomes

As described above, the condition 1 in which the edge scraper 20 and the plurality of honeycomb scrapers 30 form a closed curved surface, and the bottom surfaces of the edge scraper 20 and the plurality of honeycomb scrapers 30 are located on the same plane. By condition 2 in which right-angled corners 20a and 30a are formed on both sides of the bottom surface, and condition 3 in which the edge scraper 20 and a plurality of honeycomb scrapers 30 are made of PP material, the The paint contaminants (P) are easily removed, and at the same time, scratches or scratches are not left on the glass window (G).

The noise blocking protrusions 22 and 32 maintain a state in which the bottom surfaces of the edge scraper 20 and the plurality of honeycomb scrapers 30 pressed toward the glass window G are slightly spaced apart from the surface of the glass window G. This prevents high-frequency noise from being generated.

In general, when there are many parts that make line contact with the glass window, frictional resistance increases and friction noise is generated. In the present invention, the noise blocking protrusions 22 and 32 are the edge scrapers 20 and the bottom surfaces of a plurality of honeycomb scrapers 30 . A fine spaced space is formed between the and the glass window (G). Accordingly, it is possible to minimize the frictional resistance by preventing the edge scraper 20 and the honeycomb scraper 30 from being in direct contact with the glass window G, thereby preventing the generation of high-frequency noise.

On the other hand, on the bottom surface of the edge scraper 20 and the plurality of honeycomb scrapers 30, as shown in FIG. 3, a plurality of noise blocking protrusions 22 having a height of 0.02 to 0.1 mm, preferably 0.05 mm ( 32) is formed as one body.

Here, when the height of the noise blocking protrusions 22 and 32 is less than 0.02 mm, the noise is blocked when the edge scraper 20 and the honeycomb scraper 30 are pressed toward the glass window (G) to remove the paint contaminants (P). The protrusions 22 and 32 are finely pressed, and accordingly, the bottom surfaces of the edge scraper 20 and the honeycomb scraper 30 are not separated from the glass window G, thereby generating high-frequency noise. And when the height of the noise blocking protrusions 22 and 32 is greater than 0.1 mm, the edge scraper 20 and the honeycomb scraper 30 are pressed toward the glass window G to remove the paint contaminants (P). ) and the bottom surface of the honeycomb scraper 30 maintains a state spaced apart from the glass window G, so that the paint contaminants P cannot be properly removed.

FIG. 4 is a view for explaining the formation of a water film on a glass window contaminated with paint contaminants, FIG. 5 is a view for explaining a process of removing paint contaminants by attaching a contaminant device to the window of FIG. 4 , FIG. 5 is a diagram for explaining how the edge scraper and the honeycomb scraper scrape and remove the paint contamination device from the glass window, and FIG. 7 is a diagram for explaining the process of squeezing the paint contamination separated in FIG. 6 .

4 and 6 are diagrams for explaining a method of removing paint contaminants from a glass window using the removal device of FIGS. 1 and 2 .

First, as shown in FIG. 4, a step (S1) of forming a water film (W) on the surface of the glass window (G) by spraying water on the glass window (G) contaminated with the paint contaminant (P) is performed (S1). . The water sprayed in step S1 forms a water film W on the surface of the glass window G, and at the same time, some of it is absorbed by the paint contaminant P, thereby weakening the van der Waals force between the particles constituting the paint contaminant P. make it

Next, as shown in FIG. 5, in a state in which the bottom surfaces of the edge scraper 20 and the plurality of honeycomb scrapers 30 of the contaminant removal device 100 are in close contact with the glass window G, draw a circle or A step (S2) of separating the paint contaminants (P) from the surface of the glass window (G) is performed while moving in the direction. By step S2, as shown in FIG. 6 , the bottom surfaces of the edge scraper 20 and the honeycomb scraper 30 scrape and remove the paint contaminants P while sliding on the water film of the glass window G. .

Incidentally, the paint contaminants that contaminate the glass window (G) in the process of building construction or repainting have different properties from the paint normally painted on the wall.

Looking closely at the paint contaminants P that contaminate the window G, the particles of the paint contaminants form a small independent structure, so the contact area with the window G is small and the adhesion is small. possible. Therefore, it can be removed without a conventional chemical cleaning method or a metal scraper blade.

The present invention forms a water film by spraying water on the glass window (G) and at the same time makes the paint contaminants (P) absorb water to further weaken the adhesion with the surface of the glass window (G), and then the edge scraper 20 and a plurality of As the honeycomb scraper 30 smoothly slides along the water film, it scrapes and removes the paint contaminants (P).

In addition, noise blocking projections 22 and 32 are formed on the bottom of the edge scraper 20 and the plurality of honeycomb scrapers 30, so that the bottom surface of the edge scraper 20 and the plurality of honeycomb scrapers 30 and the glass window G ), and by preventing the bottom surface of the edge scraper 20 and the plurality of honeycomb scrapers 30 and the glass window G from being in direct contact with each other, high-frequency noise is not generated. Even if the bottom surfaces of the edge scraper 20 and the plurality of honeycomb scrapers 30 are partially in close contact with the glass window G, the edge scraper 20 and the plurality of honeycomb scrapers 30 are made of a soft PP material. The generation of high-frequency noise can be further prevented.

Next, as shown in Figure 7, using a known squeeze (Q) having a soft blade (Q1) to remove the paint contaminants (P) separated from the surface of the glass window (G) (S3) is performed . In step S3, a clean finish is obtained by pushing and removing the paint contaminants P separated from the surface of the glass window G with a squeeze Q.

By using water, not soapy water, the present invention can cleanly finish the window (G) using only the squeeze (Q).

When the water film is formed by using soapy water instead of water in step S1, the paint contaminants (P) separated from the surface of the glass window (G) are removed with a squeeze (Q) and then rinsed with clean water. If the rinsing operation is not performed, soap bubbles (bubbles) are generated in the process of proceeding to step S3 to adsorb surrounding dust, and also to form a fine film of different refractive index on the glass window (G) to form a fine film when sunlight passes through it. will leave a residue

As described above, the contaminant removal device 100 of the present invention is formed to protrude downward along the bottom edge of the plate body 10, and has an edge scraper 20 having a flat bottom surface and a plurality of honeycomb scrapers 30. As a result, it is possible to quickly separate and remove the paint contaminants (P) applied to the glass window, and in this process, no scratches or scratches are generated, so that the damage compensation application can be fundamentally removed. In particular, since the rim scraper 20 as well as the plurality of honeycomb scrapers 30 scrape and remove the paint contaminants P applied to the glass window G, workability can be improved.

In addition, since high-frequency noise is not generated in the process of removing the paint contaminants (P), it is possible to prevent the operator or surrounding people from feeling unpleasant by the noise.

Although the present invention has been described with reference to one embodiment shown in the drawings, which is only exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
