Description

  The present invention relates to a bathroom floor.

  As a floor panel used in a bathroom washroom, a plurality of convex portions are provided on the surface, and drainage grooves (water conduits) that make it possible to temporarily capture water flowing between these convex portions without interrupting the drainage concave portions. There has been disclosed one in which residual water is not generated on the floor panel by continuously forming the drainage recess (for example, Patent Document 1). This prevents water droplets from remaining on the washroom the next day.

  However, an edge formed in a planar shape may be formed around the drain recess for design purposes, and in this case, the water continuously connected in the drain groove is the edge. There is a concern that the water will be interrupted and residual water will be generated around the drain recess.

Therefore, in Patent Documents 2 and 3, a groove is also formed at the edge around the drainage recess so that the downstream ends of all drainage grooves extending toward the drainage recess are continuous to the standing surface of the drainage recess. ing.
Japanese Patent No. 3508761 Japanese Patent No. 4060638 Japanese Patent No. 3585911

  However, in Patent Documents 2 and 3, since all of the drainage grooves extending toward the drainage recess are formed with their downstream ends continuous to the standing surface of the drainage recess, the drainage performance of the drainage groove downstream portion is good. It is too much, and the water breaks off early at that part, making it difficult to temporarily capture the water flowing into the drainage groove without interrupting the drainage recess, and there is a risk that residual water may be generated around the drainage recess. is there.

  ADVANTAGE OF THE INVENTION According to this invention, the washroom floor which can prevent that residual water generate | occur | produces on the surface of a washroom floor, especially around a drainage recessed part is provided, without water being interrupted early in the downstream of a drainage groove.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a plan view of a bathroom floor 1 according to an embodiment of the present invention.

  The washroom floor 1 is waterproof so that hot water does not leak outside the bathroom, and is not sufficiently bent or damaged even when subjected to static loads such as bathroom wall panels, ceiling panels, bath chairs, and washbasins, and dynamic loads of users. For example, it is made of a thermosetting resin such as FRP (Fiber Reinforced Plastic). Alternatively, the washing floor 1 may be formed from a reinforced thermoplastic resin such as polypropylene or polyethylene.

  The washing floor 1 is formed in a shallow bread shape as a whole. The washroom floor 1 includes a drainage recess 6 formed in a concave shape, a surface 2 that is inclined downward toward the upper end of the drainage recess 6, and a water return wall 9 that is formed upward at the outermost edge portion. Is provided.

  The washing floor 1 is provided with a drainage gradient so that the drainage recess 6 is lowest, and water (including hot water) on the surface 2 flows along the drainage gradient and is collected in the drainage recess 6. Specifically, the surface 2 is formed with a plurality of gradient surfaces (for example, three gradient surfaces 3, 4, 5) having different drainage directions. Each of the gradient surfaces 3, 4, 5 is inclined downward toward the drain recess 6. Further, the gradient surface 3 and the gradient surface 4 are also inclined downward toward the ridge line 7 formed as a valley between them. Similarly, the gradient surface 3 and the gradient surface 5 are inclined downward toward the ridgeline 8 formed as a valley between them.

  Accordingly, the water on each of the gradient surfaces 3 to 5 flows toward the drain recess 6 and the ridges 7 and 8 as indicated by the dotted arrows in FIG. The ridge lines 7 and 8 themselves are also inclined downward toward the drain recess 6, and the water that has flowed into the ridge lines 7 and 8 flows to the drain recess 6 along the ridge lines 7 and 8.

  As shown in FIG. 2, a plurality of convex portions 11 and a plurality of drain grooves 12 are formed on the surface 2. Although only a part of the surface 2 is shown in FIG. 2, the convex portion 11 and the drainage groove 12 are formed over the entire surface 2 of the washing floor 1.

  The convex portion 11 has a function of preventing slipping. For example, in the example shown in FIG. 2, the surface of the convex portion 11 is formed in a corrugated shape, thereby further enhancing the antiskid effect.

  A plurality of drain grooves 12 are formed, for example, in a lattice shape so as to surround the periphery of the convex portion 11, and each drain groove 12 is continuous without interruption. Through these drainage grooves 12, it is possible to slowly drain the water flowing between the convex portions 11 to the drainage concave portion 6 without interruption.

  The planar layout of the drain grooves 12 is not limited to a lattice shape, and any layout that can slowly drain the water flowing between the convex portions 11 to the drain concave portions 6 without interruption.

  Next, FIG. 3 is an enlarged perspective view of the drain recess 6 and its peripheral part in the washing floor 1, and FIG. 4 is an enlarged plan view of the part.

  The drainage recess 6 includes a bottom surface portion 31 in which a through hole connected to a drain trap (not shown) is formed, and a standing surface portion 32 that rises upward from the periphery of the bottom surface portion 31 and is formed as a cylindrical side wall.

  Of the plurality of drain grooves 12 formed toward the drain recess 6, only a part of the downstream end is formed to extend to a height below the upper end 32 a of the standing surface 32 of the drain recess 6. That is, the downstream portion of the drainage groove 12 has a water guide groove portion 21a continuously formed to a height equal to or lower than the upper end 32a of the standing surface portion 32 in order to guide water downstream of the drainage groove 12 from the upper end 32a of the standing surface portion 32. In order to delay the flow rate of water downstream of the drainage groove 12, the downstream end is positioned on the surface 2 around the drainage recess 6, so as to be interrupted in the middle without being continued to the upper end 32 a of the standing surface portion 32. And a flow velocity suppression unit 22 that performs

  Each of the water guide groove portions 21 a to 21 f is continuous with any one of the drain grooves 12 positioned between the convex portions 11, and the downstream end of each of the water guide groove portions 21 a to 21 f extends below the upper end 32 a of the standing surface portion 32 of the drain recess portion 6. It is formed to extend.

  In this embodiment, for example, the water guide groove portions 21a to 21f are formed at six locations. The water guiding groove portions 21a and 21b are formed in the vicinity of the downstream end portions of the ridgelines 7 and 8 of the gradient surfaces 3 to 5 described above. The water guide groove portions 21d and 21e are formed in the vicinity of the downstream end portion of the gradient surface 3 and between the water guide groove portion 21a and the water guide groove portion 21b. The water guide groove 21 c is formed in the vicinity of the downstream end portion of the gradient surface 5, and the water guide groove 21 f is formed in the vicinity of the downstream end portion of the gradient surface 4.

  A planar edge 33 is formed around the upper opening end of the drain recess 6. The surface of this edge part 33 is the same height as the bottom of the drainage groove 12 located between the convex parts 11, and each water guide groove part 21a-21f is formed in the edge part 33 at slit shape. Therefore, the bottoms of the water guide groove portions 21 a to 21 f formed in the edge portion 33 are at a position lower than the bottom of the drainage groove 12 between the convex portions 11.

  On the downstream side of the drainage groove 12, the downstream end thereof is not continuously formed up to the edge portion 33, and what is interrupted before the edge portion 33 functions as the flow rate suppressing portion 22.

  As shown in FIG. 4, the downstream portion of the drainage groove 12 is connected, for example, in a lattice pattern upstream from the edge portion 33, and the water guide groove portions 21 a to 21 f and the flow velocity suppressing portion 22 are connected through this portion.

The water on the washing floor surface 2 flows into the drainage grooves 12 between the convex portions 11 and is in a temporarily trapped state continuously in the drainage grooves 12, while maintaining that state, the drainage gradient described above causes the water to flow downstream. Through the flow and the water guide groove portions 21a to 21f, the water is guided from the upper end 32a of the standing surface portion 32 of the drain recess 6 to the lower side. Further, the flow rate suppression unit 22 that interrupts the drainage groove 12 on the upstream side of the upper end 32 a of the standing surface part 32 of the drainage recessed part 6 suppresses the drainage speed (drainage) at that part, and on the downstream side of the drainage groove 12. It can suppress that the water which flows in the groove | channel 12 interrupts at an early stage.
As a result, it is possible to maintain the continuous water trapping state of the continuous water in the drainage groove 12 for a long time, and slowly and gradually the water in the drainage groove 12 through the water guiding grooves 21a to 21f to the drainage recess 6. Can flow down.
Here, if the flow rate of the drainage downstream of the drainage groove 12 is faster than that of the upstream side, the drainage in the groove on the downstream side disappears early, the continuous flowing water network leading to the drainage recess 6 is interrupted, and the washing floor 1 In addition, there is a risk of producing an amount of residual water that is difficult to air dry by the next day.
Therefore, if the flow rate of the drainage on the downstream side of the drainage groove 12 is about the same as or slower than that on the upstream side, the continuous flowing water network is not interrupted to the standing surface portion 32 of the drainage recess 6. That is, it is important that the downstream side of the drainage groove 12 can drain more slowly.
Therefore, in the embodiment of the present invention, in order to suppress the drainage flow velocity on the downstream side, the downstream ends of all the drainage grooves 12 extending toward the drainage recess 6 are not continued to the standing surface portion 32 of the drainage recess 6. However, only a part is continued to the standing surface portion 32 of the drainage recess 6 through the water guide groove portions 21a to 21f.

  Therefore, in this embodiment, by suppressing the water guiding groove portions 21a to 21f connected to the drain recess 6 without interruption, the improvement in drainage more than necessary on the downstream side is suppressed, and the floor 2 on the washing place is suppressed. The temporary water catching state in which the drainage is continuously connected to the drain recess 6 can be reliably maintained, and the generation of residual water left on the washing floor surface 2 and around the drain recess 6 can be suppressed.

  The water on the washing floor surface 2 is likely to gather on the ridgelines 7 and 8 of the gradient surfaces 3 to 5 described above, and most of the water flows on the ridgelines 7 and 8 or in the vicinity thereof to the drain recess 6. 3 and 4 show an example in which the water guide groove portions 21c to 21f are formed in four places other than the downstream end portions of the ridge lines 7 and 8, the water guide groove portion 21a is formed only in the downstream end portions of the ridge lines 7 and 8. , 21b and only the drain groove 12 is made continuous with the standing surface portion 32 of the drain recess 6 only at that portion, is sufficient to prevent water pooling around the drain recess 6.

  As described above with reference to FIG. 4, the water guiding groove portions 21 a to 21 f and the flow velocity suppressing portion 22 are continuous through the drain grooves 12 on the upstream side from the respective downstream ends. Therefore, the water in the flow velocity suppression unit 22 formed near the water guide groove portions 21a to 21f can flow into the water guide groove portions 21a to 21f. As a result, the amount of water remaining in the flow rate suppression unit 22 can be made extremely small. If the amount of the remaining water is small, it is naturally dried and dried sufficiently by the next day.

  The washing floor 1 described above is integrally molded by hot molding SMC (Sheet Molding Compounds: sheet-shaped molding material in which unsaturated polyester resin, glass fiber, filler, etc. are mixed). At this time, for example, when a DAP (diallyl phthalate) resin sheet is inserted between the mold and the SMC to form a concavo-convex pattern for a surface design, in this embodiment, in the vicinity of the drain recess 6 Since the planar edge 33 is formed on the surface, the DAP resin sheet can be closely adhered to the planar edge 33 without any gap, and the SMC flows to the inner surface 2 side from the edge 33. It can be prevented from flowing in.

  On the other hand, in Patent Documents 2 and 3, since all the drainage grooves are formed to extend to the opening edge of the drainage recess, a large number of irregularities are formed on the opening edge of the drainage recess. For this reason, even if the DAP resin sheet is overlapped on the edge, many gaps are formed between the edge and the DAP resin sheet, and SMC flows from these gaps to the wash floor surface side inside the edge, There is a concern that defects may occur in the pattern transfer formation by the resin sheet.

  In the present embodiment, as described above, not all of the plurality of drainage grooves 12 are formed to extend to the edge portion 33, but only a part thereof is formed on the edge portion 33 as water guide groove portions 21a to 21f. Most of the edge portion 33 is a flat surface, and when the DAP resin sheet and the edge portion 33 are overlapped, the gap between them can be reduced as much as possible, and the flow of SMC to the surface 2 side can be suppressed.

  Further, in the present embodiment, a satin (fine unevenness) pattern is formed on the surface of the edge portion 33, and this also contributes to the improvement of drainage because the surface of the edge portion 33 tends to be hydrophilic. .

  For example, the groove width t of the drainage groove 12 positioned between the convex portions 11 is 0.5 <t <2.0 mm, the depth is 0.5 mm or more, and the groove width t of each of the water guide groove portions 21a to 21f is 0.00. 5 <t <2.0 mm and the depth is 0.5 mm or more.

  When the washing floor 1 is manufactured by molding the above-mentioned SMC using a mold, the groove is transferred and formed when the drain width 12 or the groove width t of the water guide grooves 21a to 21f is 0.5 mm or less. Therefore, there is a concern about insufficient strength because the convex portion of the mold for the purpose becomes thin. Further, if the groove width t is 2 mm or more, there is a concern that gravity becomes larger than the water flow resistance (surface tension) and water cannot be trapped in the groove. Therefore, it is desirable that the groove width t of the drainage groove 12 and the water guide groove portions 21a to 21f be in the range of 0.5 mm <t <2.0 mm.

  Next, FIG. 5 shows a schematic enlarged cross-sectional view of the water guide groove 21. In FIG. 5, each of the water guide grooves 21 a to 21 f described above is represented by reference numeral 21.

  The water guide groove portion 21 has an upstream inclined portion 41, an intermediate portion 42, and a downstream inclined portion 43. The upstream inclined portion 41 is connected to the drainage groove 12 between the convex portions 11, and the downstream end of the downstream inclined portion 43 is located below the upper end of the standing surface portion 32 of the drainage recessed portion 6. The intermediate part 42 is formed between the upstream inclined part 41 and the downstream inclined part 43.

  The upstream inclined portion 41 is formed at a position lower than the bottom portion 12a of the drainage groove 12 between the convex portions 11, and is formed to be steeper than the gradient (for example, 1/50) of the wash floor surface 2 (drainage groove 12). ing. The intermediate part 42 is formed to have a gentle inclination similar to the gradient (for example, 1/50) of the washing floor surface 2 (drainage groove 12). The downstream inclined portion 43 is formed in a steep inclination extending downward from the upper end of the standing surface portion 32 of the drain recess 6.

  In this way, the entire water guide groove portion 21 is not steeply inclined from the upstream side to the downstream side, but there is an intermediate portion 42 having a gentle inclination similar to the gradient (for example, 1/50) of the washing floor surface 2 in the middle. Thus, the drainage speed at that portion can be suppressed, and the water break in the water guide groove 21 can be suppressed. That is, in the water guide groove 21 and the drainage groove 12 connected thereto, water can be temporarily trapped in a surely continuous state.

  The washing floor according to the above-described embodiment has a structure in which the drain recess 6 and the surface 2 are integrally formed of the same material. However, the present invention is not limited thereto, and they may be separately formed and combined.

  FIG. 6 is an enlarged perspective view of a drainage recess and its peripheral portion in a washing floor according to another embodiment of the present invention.

  In the present embodiment, the surface material 50 is bonded to a base material 57 made of, for example, FRP, in which the drain recess 6 is integrally formed. For example, by using a material softer than the base material 57 as the surface material 50, it is possible to realize a washroom floor with a soft surface.

  The gap between the edge of the surface material 50 on the drain recess 6 side and the surface of the base material 57 is filled with the caulking material 55, and water enters between the surface material 50 and the surface of the base material 57 from the gap. It prevents that.

  A plurality of convex portions 51 and a plurality of drain grooves 52 are formed on the surface of the surface material 50. The convex portion 51 has a function of preventing slipping. A plurality of drain grooves 52 are formed so as to surround the periphery of the convex portion 51, and each drain groove 52 is continuous without interruption. Through these drainage grooves 52, it is possible to slowly drain the water flowing between the convex portions 51 to the drain concave portion 6 without interruption.

  Also in the present embodiment, among the plurality of drain grooves 52 formed toward the drain recess 6, only a part of the downstream end extends to a height below the upper end of the standing surface portion of the drain recess 6. In addition, the upper end of the standing surface portion of the drain recess 6 in this embodiment refers to the upper end 55a of the caulking material 55 filled in the gap between the surface of the base material 57 and the edge of the surface material 50.

  The downstream portion of the drainage groove 52 has a water guide groove portion 62 continuously formed up to a height below the upper end 55a in order to guide water downstream of the drainage groove 52 below the upper end 55a of the standing surface portion, and downstream of the drainage groove 52. In order to delay the flow rate of the water on the side, the flow rate suppressing unit 63 is formed so as to be interrupted in the middle without being continued to the upper end 55a, and the downstream end is positioned on the surface material 50.

  Also in this embodiment, the water guide groove 62 is formed at least in the vicinity of the downstream end of the ridge line of the inclined surface. Further, the water guiding groove 62 and the flow velocity suppressing part 63 are continuous through the drainage grooves 52 upstream from the respective downstream ends.

  Also in the present embodiment, by suppressing the water guiding groove 62 connected to the drain recess 6 without interruption, the drainage recess is suppressed from the surface of the surface material 50 by suppressing the improvement of drainage more than necessary on the downstream side. Thus, it is possible to reliably maintain a temporary water catching state in which drainage is continuously connected to 6, and to suppress generation of residual water left on the surface of the surface material 50 and around the drainage recess 6.

  In the present embodiment, the water guide groove 62 may be formed to extend to the standing surface 57 a of the base material 57 below the caulking material 55.

  Moreover, in each embodiment mentioned above, the amount of the water which remains on a convex part, without contacting the water in a drain groove is 2 cc or less, Preferably it is 0.2 cc or less.
