It is a typical fragmentary perspective view which shows the position where the position of the recessed part and a notch part has corresponded (it connects in the top view) in the floor.

  As shown in FIGS. 1-5, the bathroom 100 which concerns on embodiment of this invention is the bathtub 1 which a bather can take a bath by storing hot water, the washing-room floor 3 which a bather can walk, and a bather A room entrance door (not shown), a bathroom wall (not shown) provided so as to surround four sides of the bathroom space, and a bathroom ceiling (not shown) connected to the top of the bathroom wall It is equipped with.

  The wash floor 3 includes a wash floor main body 2 and a drain pit 14. The washing floor main body 2 includes a base 4, a plurality of convex portions 6 formed above the base portion 4, and a concave portion (groove portion) 8 formed continuously between the plurality of convex portions 6. The recesses 8 are continuously connected to each other. The surface of the convex part 6 and the concave part 8 is subjected to a hydrophilic treatment. The surfaces of the convex portion 6 and the concave portion 8 are coated with a hydrophilic paint. By coating the surfaces of the convex portions 6 and the concave portions 8 with a hydrophilic paint, polka-dot residual water is hardly generated on the surfaces of the convex portions 6 and the concave portions 8. Specific examples of the hydrophilic paint include hydrophilic properties such as —OH, —O—, —NHCO—, —CONH 2, —COOH, —SO 3 H, —OPO (OH) 2, —NH 2, —NH—, —NR 2, and the like. Examples thereof include a hydrophilic paint composed of a polymer having a functional group and a solvent. The washing floor 3 is preferably formed so that the contact angle of water droplets adhering to the surfaces of the convex portions 6 and the concave portions 8 is, for example, 40 degrees or less, more preferably 25 degrees or less.

  The drainage pit 14 is connected to the drainage edge 10 formed on the washing ground floor body 2 from below. That is, the washing floor main body 2 is a separate body (separate member) from the drain pit 14. The drain pit 14 is made of, for example, polypropylene. The surface of the drain pit 14 is not coated with a hydrophilic paint, and the hydrophilic performance is lower than the surface of the washing floor main body 2. In other words, the surface of the drainage pit 14 has higher water repellency than the surface of the washing floor main body 2. The contact angle of water droplets adhering to the surface of the drain pit 14 is, for example, 90 degrees or more.

  As shown in FIGS. 3 to 5, the drain pit 14 includes a standing wall surface portion 16, a water guide path portion 18, and a notch portion (notch groove) 20. The standing wall surface portion 16 is a wall surface formed substantially vertically (for example, at an inclination angle of 80 to 100 degrees) so as to surround the periphery of the drain port 12. The water guide path portion 18 is formed at the upper end of the drainage pit 14 in contact with the standing wall surface portion 16 and the drainage edge portion 10. The notch 20 is a groove formed inward from the standing wall 16 so as to be connected to the water guide path 18.

  In the vicinity of the opening 22 connected to the recess 8 provided in the drain edge 10, the end of the recess 8 connected to the drain edge 10 has a shape that spreads in a V shape when viewed from above.

  The surface of the washing floor main body 2, for example, the surface of the convex portion 6 and the concave portion 8 is inclined toward the drain pit 14. This inclination angle is, for example, about 0.5 to 5 degrees. As a result, the water accumulated on the surface of the recess 8 gradually flows without interruption in the direction of the drain pit 14, that is, toward the drain edge 10. At this time, as described above, since the surfaces of the convex portions 6 and the concave portions 8 are subjected to a hydrophilic treatment, water adhering to the surface of the convex portions 6 easily spreads, and the spread water is combined with the water accumulated in the concave portions 8. By doing so, the water adhering to the surface of the convex part 6 also becomes easy to flow toward the drain edge 10 without interruption.

  The water guide path portion 18 includes drainage connection means that suppresses the water accumulated in the recessed portion 8 from being interrupted with respect to the water accumulated on the water guide path portion 18. This drain connection means will be described in detail later.

  The notch 20 has surface tension increasing means for making the surface tension generated in the water entering the notch 20 larger than the surface tension generated in the water accumulated in the recess 8. This surface tension increasing means will be described in detail later.

  FIG. 6 is a schematic partial cross-sectional view showing the washing ground floor of FIG.

As shown in FIG. 6, the distance X1 from the upper end of the standing wall surface portion 16 to the drainage edge portion 10 (distance X1 from the upper end of the standing wall surface portion 16 to the base portion 4) in the water guide passage portion 18 is the lower end of the washing ground floor body 2 Is greater than the distance Y from the lower end of the recess 8 to the lower end of the recess 8. In other words, the width direction length X1 of the water guide path portion 18 is larger than the thickness Y of the base portion 4. With such a configuration, the height of the water that can be accumulated in the water guide path portion 18 is easily made higher than the lower end of the recessed portion 8.
If the distance from the upper end of the standing wall surface to the drainage edge in the water guide channel is smaller than the distance from the lower end to the bottom of the recess in the washing floor main body, the height of the water accumulated in the water guide channel is Before it grows higher than the lower end, it flows down from the standing wall. If it is such a washing place floor, the water accumulated in the concave portion and the water accumulated on the water guide path portion 18 are not connected, and the water accumulated in the concave portion is stagnated without properly flowing to the drain outlet.
On the other hand, in the washing place floor 3 according to the embodiment of the present invention, the distance X1 from the upper end of the standing wall surface portion 16 to the drainage edge portion 10 in the water guide passage portion 18 is from the lower end of the washing place floor main body 2 to the lower end of the recess 8. Since it is larger than the distance Y, the water accumulated in the recess 8 can be appropriately connected to the water accumulated on the water guide path 18 so as not to be interrupted.
Therefore, the distance X1 from the upper end of the standing wall surface portion 16 to the drainage edge portion 10 in the water guide path portion 18 is made larger than the distance Y from the lower end to the lower end of the recess 8 in the washing ground floor main body 2. One.
In addition, it is possible to make the distance X2 from the position where the upper end R of the standing wall portion 16 in the water guide path portion 18 starts to the drainage edge portion 10 larger than the distance Y from the lower end of the washing floor main body 2 to the lower end of the recess 8. Is more preferable.

  FIG. 7 is a schematic partial cross-sectional view showing a bathroom floor in a modified example according to the embodiment of the present invention.

As shown in FIG. 7, for example, in the water guide path portion 18, the upper end of the standing wall surface portion 16 may be formed at a position higher than the position in contact with the drainage edge portion 10. As a result, the water accumulated in the water guide path portion 18 naturally gathers from the upper end of the standing wall surface portion 16 to the drainage edge portion 10. As a result, the height of the water accumulated in the vicinity of the drainage edge portion 10 of the water guide passage portion 18 is easily made higher than the lower end of the concave portion 8. Therefore, the water accumulated in the concave portion 8 can be appropriately connected to the water accumulated on the water guide path portion 18 so as not to be interrupted.
Therefore, forming the upper end of the standing wall surface portion 16 at a position higher than the position in contact with the drainage edge portion 10 in the water guide path portion 18 is also one of the drainage connection means.

  More preferably, an inclined surface that is inclined from the upper end of the standing wall surface portion 16 toward the position in contact with the drainage edge portion 10 may be formed in the water guide path portion 18. As a result, the water accumulated in the water guide path portion 18 gathers from the upper end of the standing wall portion 16 to the drainage edge portion 10.

The depth of the notch 20 is greater than the depth of the recess 8. Thereby, the surface tension generated in the water in the notch 20 becomes larger than the surface tension of the water in the recess 8, and the water accumulated in the recess 8 is not interrupted with respect to the water accumulated on the water guide path 18. In the connected state, water can be discharged by the notch portion 20 formed in the standing wall surface portion 16 so as to be connected to the water guide path portion 18. The depth of the notch 20 is preferably 1.0 mm or more.
Accordingly, one of the means for increasing the surface tension is to make the depth of the notch 20 larger than the depth of the recess 8.

The width of the notch 20 is smaller than the width of the recess 8. Thereby, the surface tension generated in the water in the notch 20 becomes larger than the surface tension of the water in the recess 8, and the water accumulated in the recess 8 is not interrupted with respect to the water accumulated on the water guide path 18. In the connected state, water can be discharged by the notch portion 20 formed in the standing wall surface portion 16 so as to be connected to the water guide path portion 18. The width of the notch 20 is preferably 3.5 mm or less.
Therefore, making the width of the notch 20 narrower than the width of the recess 8 is one of the surface tension increasing means.

The surface roughness of the notch 20 is greater than the surface roughness of the recess 8. Thereby, the surface tension generated in the water in the notch 20 becomes larger than the surface tension of the water in the recess 8, and the water accumulated in the recess 8 is not interrupted with respect to the water accumulated on the water guide path 18. In the connected state, water can be discharged by the notch portion 20 formed in the standing wall surface portion 16 so as to be connected to the water guide path portion 18.
Therefore, making the surface roughness of the notch 20 larger than the surface roughness of the recess 8 is one of the surface tension increasing means.

8 and 9 are schematic partial perspective views showing the flow of drainage on the washing ground floor in FIG.
FIG. 10 is a schematic partial cross-sectional view showing a notch portion of a drainage pit on the washing ground floor of FIG.
FIG. 8 is a schematic partial perspective view showing a flow of drainage on the washing ground floor in FIG. 2 in an initial state where residual water is discharged from the washing floor in particular, and FIG. It is a typical fragmentary perspective view which shows the flow of the waste_water | drain in the washroom floor of FIG. 2 in the final state in which residual water discharge is performed. In FIG. 8 and FIG. 9, what is indicated by an arrow is a virtual flow of water.

  As described above, the surfaces of the convex portion 6 and the concave portion 8 are subjected to a hydrophilic treatment, and the water adhering to the surface of the convex portion 6 spreads and the spread water is combined with the water accumulated in the concave portion 8. The water accumulated on the surface of the recess 8 gradually flows to the drainage edge 10 along the drainage gradient provided toward the drainage pit 14. Since the drainage gradient (inclination angle) is very gentle as described above, the water accumulated on the surface of the recess 8 slowly flows to the drainage edge 10.

The water in the concave portion 8 that has reached the vicinity of the drainage edge portion 10 is combined with the water accumulated on the surface of the water guide path portion 18 by the drainage connection means described above. Since the water accumulated on the surface of the water guide path 18 is connected to the water flowing down from the notch 20, the water flowing down from the notch 20 is gradually drawn into the notch 20 and discharged to the drain port 12. Is done.
By these series of flows, the water accumulated on the surface of the washing ground floor main body 2, the water accumulated on the surface of the water guide path portion 18, and the water in the notch portion 20 are discharged to the drain outlet while being connected to each other. It will be.

  Further, the surface tension acting on the water in the notch 20 becomes larger than the surface tension acting on the water collected on the surface of the washing ground floor body 2 by the surface tension increasing means described above. Even when pulling between the water in the notch 20 and the water in the notch 20 via the water accumulated on the surface of the water guide path 18 occurs, The water collected on the surface of the main body 2 and the water collected on the surface of the water guide path portion 18 can be securely drawn into the cutout portion 20.

At this time, since the surface tension increasing means can discharge water strongly, if the number of the cutout portions 20 is large, the amount of water flowing down from the cutout portions 20 is excessively increased, and the water guide path. There is a possibility that water accumulated on the surface of the portion 18 is discharged at once and the water is interrupted.
On the other hand, in the washing place floor 3 according to the embodiment of the present invention, as shown in FIGS. 2 and 5, the number of the notches 20 is less than the number of the recesses 8 connected to the water guide path 18. In other words, the number of notches 20 is less than the number of openings 22 connected to the recesses 8 provided in the drainage edge 10. Thereby, even when water is strongly discharged by the surface tension increasing means, it is possible to suppress the water accumulated on the surface of the water guide path portion 18 from being discharged at once and the water being interrupted.

  As shown in FIG. 9, particularly when the remaining water on the washing floor 3 is reduced, it is not from the position near the standing wall surface 16 in the notch 20 but on the washing floor main body 2 side in the notch 20. It is easy to flow from the position. As shown in FIGS. 9 and 10, the curvature of the position where the upper end 23 on the water guide path 18 side of the notch 20 is connected to the water guide path 18 is the same as that on the washing floor main body 2 side of the notch 20. This is because it is smaller than the curvature of the curved surface 24 which is the upper end. That is, the upper end 23 of the notch 20 on the side of the water conveyance path 18 is formed to be sharper than the upper end of the notch 20 on the side of the washing floor main body 2. As a result, when the amount of water collected in the water guide path 18 is reduced, the water collected in the water guide path 18 falls from the upper end 23 of the notch 20 on the side of the water guide path 18 to the notch 20. On the other hand, the water flowing relatively slowly along the curved surface 24 with a gentle curvature from the upper end of the notch 20 on the washing body floor main body 2 side to the notch 20, and the water guide path of the notch 20 It becomes easy to couple | bond with the water of the water conveyance path | route part 18 which accumulated on the upper end 23 by the side of the part 18. FIG. Therefore, especially when the remaining water on the washing floor 3 is reduced, it is easy to flow from the position on the washing floor main body 2 side in the notch 20 instead of from the position near the standing wall surface 16 in the notch 20. . From this, particularly when the remaining water on the washing floor 3 is reduced, the water accumulated in the water guide path 18 can be collected and flowed down from the notch 20.

  As shown in FIG. 10, a gap that is a semi-hiding space is provided between the lower end surface of the washing floor main body 2 (the lower end surface of the base 4) and the curved surface 24 that is the upper end of the notch 20 on the washing floor main body 2 side. Is formed. Thereby, the magnitude | size of the surface tension which acts on the water which entered the clearance gap of the upper end by the side of the washing-room floor main body 2 of the notch part 20 can be increased locally, and it is close to the standing wall surface part 16 in the notch part 20 It becomes easier to flow not from the position but from the position on the wash floor main body 2 side in the notch 20. For this reason, particularly when the remaining water on the washing floor 3 is reduced, the water accumulated in the water guide path 18 can be collected and flowed down from the notch 20.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions.
