Japanese Patent No. 4757048 JP 2007-37982 A

  Conventionally, when such a cleaning mop is used to clean a floor or the like, a cleaning member such as paper or cloth almost covers and touches the floor surface, so that it adheres to the bottom surface of the cleaning member and is collected. The percentage of dust that accumulates on the front side of the duster mop head is overwhelmingly higher than that of dust. Also, when dust is trapped on the bottom surface of the cleaning member, if there is hard dust such as earth and sand, the soft wax film on the floor will be rubbed with the hard earth and sand every time the duster mop head is moved. Is damaged, and dirt enters the wound, which increases the darkening of the floor. Further, if the duster mop head is moved in a state where dust is collected at the front part, there is a problem that dust is likely to be scattered. In addition, the conventional cleaning mop requires replacement and cleaning whenever the cleaning member such as paper or cloth gets dirty, especially in the case of cloth, which requires washing, disinfection and drying after use. There is a lot of time and cost.

  Therefore, the present invention has been made to solve such a problem, and compared with a conventional cleaning mop, the possibility of damaging the floor surface is low, dust scattering is small, and cleaning members can be replaced or cleaned. An object is to provide an unnecessary cleaning tool.

  In a first aspect, the present invention includes a dust collection head that covers a floor surface from above and is open on the floor surface side, and a handle attached to the dust collection head, and the dust collection head includes at least the floor surface. The contact portion is made of a flexible material, and has an opening having one side on the floor surface provided on the front surface, an internal space, and a vent hole provided in a part of the side surface or the rear surface, The upper end of the inner space is fixed, the lower end is in contact with the floor surface, the side surfaces are separated from each other, and at least a contact portion with the floor surface is provided with a plurality of flexible structures, There is provided a cleaning tool characterized in that dust entering from the opening of a head is captured in the internal space.

  In the cleaning tool of the invention of this aspect, the dust on the floor surface moves into the internal space through the opening on the front surface of the dust collection head by moving the dust collection head forward on the floor surface using the handle. At this time, since there are a plurality of structures in contact with the floor surface in the internal space, the dust that has entered through the openings mainly adheres to the front and side surfaces of these structures. Dust also adheres to the front and side surfaces of conventional duster mop heads, but the cleaning tool of the present invention has a plurality of structures separated from each other, and the total length of the front and side surfaces is It is larger than the total length of the front and side surfaces of a conventional duster mop head. Therefore, the amount of dust that can be attached to the cleaning tool of the present invention is much larger than that of the conventional duster mop head. In addition, since there are ventilation holes on the side or rear, air flow including dust is generated from the front side to the rear side, and the dust that has entered and adhered to the structure is pushed from the front side to the rear side, Dust gradually accumulates on the rear side in the space. In this case, the installation location and shape of the vent hole are selected so that the captured dust is not easily discharged from the dust collection head. Further, the vent hole may be provided with a filter that blocks dust and allows only air to pass through. The shape, number, and arrangement of the structures are set in consideration of the air flow from the front side to the rear side, the adhesion of dust to the side surfaces of the structure, and the like. In this case, it is also possible to configure and arrange the structure asymmetrically so as to generate an air current that collects dust while rotating.

  As described above, in the cleaning tool of the present invention, dust is trapped in the internal space, so that dust accumulated on the front surface does not scatter like a conventional duster mop head. In addition, the entire head does not contact the floor as in the conventional duster mop head cleaning member, but only the contact portion of the structure and the enclosure of the dust collecting head contact the floor, so the contact area with the floor Is small. Further, since there is a flow of air containing dust in the internal space, the dust is often attached to the side surface of the structure or trapped in the internal space rather than being sandwiched between the lower surfaces of the contact portions. As a result, compared to conventional duster mop heads, the possibility of damaging the floor surface with dust sandwiched between the contact portions is low. Moreover, since the dust accumulated in the internal space has only to be appropriately discarded, it is not necessary to replace the cleaning member.

  Here, the material having the flexibility of the contact portion with the floor surface of the dust collecting head and the contact portion with the floor surface of the structure is the same material as the cleaning member of the conventional duster mop head, that is, cloth, paper, It may be a sponge, rubber, or even a brush. In addition, the entire structure may be made of the above-described flexible material, while the enclosure portion of the dust collecting head is made of a hard material such as a plastic plate or a metal plate except for the contact portion with the floor surface. It may be configured. In addition, the planar shape seen from the upper surface of the dust collecting head and the cross-sectional shape perpendicular to the floor surface can be not only a rectangle but also a circle, a part of an ellipse, or any other shape.

  In a second aspect, the present invention is the cleaning tool according to the first aspect, wherein the width of the opening is approximately the same as the width of the dust collecting head. With such a configuration, since the opening is formed to the full width of the dust collecting head, the corner portion of the room can be easily cleaned.

  In a third aspect, the present invention provides the cleaning tool according to the first or second aspect, wherein the cross-sectional shape parallel to the floor surface of the structure has a shape that becomes narrower toward the front end on the front side. It is characterized by being. In the invention of this aspect, a plurality of cross-sectional shapes having a width that narrows toward the tip on the front side, such as a triangle with one apex facing forward or a rhombus with an acute apex facing forward, Arrange the structure in the internal space. As a result, the space excluding the structure in the vicinity of the opening of the internal space becomes narrower toward the inside, and the air flow from the opening hits the side surface of the structure, so that the dust structure entering from the opening Adhesion to the side surface is likely to occur.

  In a fourth aspect, the present invention provides the cleaning tool according to any one of the first to third aspects, wherein the dust collection head has a substantially rectangular parallelepiped shape with a front surface as one surface, and a part of the rear surface of the dust collection head. It has the vent hole. As in the invention of this aspect, when the dust collection head has a rectangular parallelepiped shape, that is, a box shape, manufacturing is facilitated, and the cost of the dust collection head can be reduced. In this case, the flow of air around the structure becomes smoother if the vent hole is provided on the rear surface than on the side surface.

  In a fifth aspect, the present invention provides the cleaning tool according to the fourth aspect, wherein the opening has a rectangular shape having one side on the floor surface, and the vent hole is provided at a constant height from the floor surface, It has a rectangular shape having one side parallel to the floor surface. With such a configuration, it becomes easy to produce an opening and a vent hole.

  In a sixth aspect, the present invention provides the cleaning tool according to any one of the first to fifth aspects, wherein the size of the space excluding the structure in the internal space of the dust collection head is the space on the rear surface side. In comparison, the space on the front side is narrower. In the invention of this aspect, the means for making the space on the rear side excluding the structure wider than the space on the front side is not only a method of adjusting the shape and the number of installations, but also the height of the internal space. This can also be realized by making the rear side higher than the front side. Thus, by enlarging the space on the back side of the internal space, it is possible to reduce obstacles to clogging of trapped dust and air flow to the rear surface side.

  In a seventh aspect, the present invention provides the cleaning mop according to any one of the first to sixth aspects, wherein at least part of the upper surface of the dust collection head can visually recognize the dust trapped in the internal space from above. It is made of a transparent material. In the invention of this aspect, the upper surface of the dust collecting head is made of a transparent material, so that the amount of dust trapped in the internal space can be confirmed from above while the dust collecting head is placed on the floor surface. Whether or not dust should be discarded can be easily determined at any time. Furthermore, by moving the dust collecting head on the floor surface and observing the amount of dust inside and its change, it is possible to determine the state of the dust amount on the floor surface and the necessity of cleaning.

  As described above, according to the present invention, it is possible to obtain a cleaning tool that is less likely to damage the floor surface, has less dust scattering, and does not require replacement or cleaning of the cleaning member, as compared to a conventional cleaning mop.

FIG. 10 is a perspective view showing a cleaning tool according to a sixth embodiment.

  Hereinafter, the cleaning tool of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description thereof is omitted.

  1A and 1B are diagrams for explaining the cleaning tool according to the first embodiment. FIG. 1A is a perspective view of the cleaning tool, FIG. 1B is a bottom view of the dust collecting head, and FIG. ) Is a front view of the dust collecting head, and FIG. 1D is a rear view of the dust collecting head. In FIG. 1A, the cleaning tool 10 of the present embodiment includes a dust collection head 11 that covers the floor surface 2 from above and is open on the floor surface side, and a handle 1 attached to the dust collection head 11. ing. The dust collection head 11 has a rectangular parallelepiped shape, and includes an upper surface plate 12 to which the handle 1 is attached, side plates 13 on both sides, and a rear surface plate 14. The front surface is opened to become an opening 15. An internal space 16 is provided inside the side plate 13, the rear plate 14 and the floor 2.

  The contact part 17 which is a part which contacts the floor surface 2 of the side plate 13 and the rear plate 14 is made of a flexible material such as cloth, sponge, or rubber. In addition, as shown in FIG. 1D, the rear plate 14 is provided with six circular vent holes 18. As shown in FIGS. 1B and 1C, the inner space 16 has four elliptical columnar shapes in which the upper end is fixed to the upper surface plate 12, the lower end is in contact with the floor surface 2, and the side surfaces are separated from each other. The structure 19 is installed. These structures 19 are made of a flexible material such as cloth, sponge, or rubber. Here, the structure 19 is comprised only from the material which has a softness | flexibility only in a contact part with the floor surface 2, and another part may be comprised with the other material. Examples of the constituent material other than the constituent parts made of a flexible material include plastic, wood, metal, and the like. As a specific example of the size of the dust collecting head 11, the width can be 10 to 120 cm, the depth is 10 to 30 cm, and the height is about 0.3 to 20 cm.

  In the cleaning tool 10 of the present embodiment, the dust collection head 11 is moved forward on the floor surface 2 by the handle 1 so that the dust on the floor surface 2 enters the internal space 16 through the opening 15 of the dust collection head 11. Most of the dust that has entered through the opening 15 adheres around the structure 19. In this case, since the total perimeter of the structure 19 is larger than the perimeter of the conventional duster mop head, the amount of dust that can be attached increases. Further, since the rear plate 14 has the ventilation holes 18, the air flow including dust is generated in the direction from the opening 15 to the back side, and the dust that has entered and the dust attached to the structure 19 are moved from the opening 15 to the back. It is pushed and gradually accumulates in the inner space 16. The vent hole 18 is installed above the rear plate 14 so that the trapped dust is not easily discharged from the dust collection head 11, and the size of the vent hole 18 is set so that the dust is not discharged.

  As described above, in the cleaning tool 10 of the present embodiment, the dust is captured in the internal space 16, and therefore the dust is not scattered. Further, since the contact area between the dust collecting head 11 and the floor surface 2 is small, and there is a flow of air containing dust in the internal space 16, the dust that has entered the contact portion and the floor surface 2 is separated. In many cases, it adheres to the side surface of the structure or is captured in the internal space 16 rather than being sandwiched between them. As a result, the possibility that the dust sandwiched between the contact portions damages the floor surface is reduced.

  2A and 2B are diagrams illustrating a dust collection head of a cleaning tool according to a second embodiment. FIG. 1A is a bottom view, FIG. 1C is a front view, and FIG. 1D is a rear view. The external shape and handle of the dust collection head of the cleaning tool of this example are the same as those of Example 1.

  The portions of the side plate 23 and the rear plate 24 that are in contact with the floor surface 2 are made of a flexible material as in the first embodiment. As shown in FIG. 2C, a rectangular vent hole 28 having one side parallel to the floor surface 2 is provided at the upper end of the rear plate 24. As shown in FIGS. 2 (a) and 2 (b), in the internal space 26, seven square pillars having an upper end fixed to the upper surface plate 22, a lower end in contact with the floor surface 2, and the side surfaces separated from each other. The structure 29 is installed. In the present embodiment, four structures on the front side and three structures on the rear side are arranged in two stages, and are arranged alternately in the front-rear direction so that the air flow is smooth. Although the outer shape of these structures is different from that of the structure 19 of the first embodiment, the material and the internal structure are the same as those of the structure 19.

  Also in the cleaning tool of the present embodiment, by moving the dust collection head 21 forward on the floor surface 2, the dust on the floor surface 2 enters the internal space 26 through the opening 25 of the dust collection head 21. Most of the dust that has entered through the opening 25 adheres around the structure 29. In this case, since the total perimeter of the structure 29 is larger than that of the structure 19 of the first embodiment, the amount of dust that can be attached is further increased. Further, since the rear plate 24 has the ventilation holes 28 and the structures 29 are alternately arranged in the front and rear, the flow of dust-containing air flows from the opening 25 toward the back side along the periphery of the structure 29. Dust is generated in the direction, and dust is pushed from the opening 25 to the back, and gradually accumulates in the back of the internal space 26. The vent hole 28 is installed above the rear plate 24 so that the captured dust is not easily discharged from the dust collecting head 21, and the size thereof is set so that the dust is not discharged.
