Since the water conveyance path portion has a notch portion formed in the water and has a drainage connecting means for suppressing the water accumulated in the groove portion from being interrupted with respect to the water accumulated on the water conveyance path portion, the drainage is drained. The water collected in the groove is connected to the water accumulated on the water conveyance path without interruption by the connecting means, and the water is discharged by the notch formed in the vertical wall so as to be connected to the water conveyance path. be able to. Therefore, it is not necessary to form a notch on the vertical wall surface of the drainage pit according to the position of the groove portion, and the water accumulated in the groove portion can be efficiently discharged to the drainage port, and the parts of the drainage pit can be standardized. ..

According to the second invention, in the first invention, the drainage connecting means sets the distance from the upper end of the vertical wall surface portion in the water conveyance path portion to the drainage edge portion, and from the lower end portion of the washroom floor body to the lower end portion of the groove portion. It is the washroom floor of the bathroom, which is larger than the distance to.

According to the washroom floor of this bathroom, the distance from the upper end of the standing wall surface to the drainage edge in the water conveyance path portion is made larger than the distance from the lower end to the lower end of the groove portion in the washroom floor body, so that the water conveyance path portion is formed. It is easy to make the height of the water that can be collected higher than the lower end of the groove. Therefore, the water accumulated in the groove portion can be connected to the water accumulated on the water conveyance path portion without interruption.

According to a third aspect of the invention, in the first invention, the drainage connecting means forms the upper end of the vertical wall surface portion at a position higher than the position in contact with the drainage edge portion in the water conveyance path portion. It is the washroom floor of the bathroom.

According to the washroom floor of this bathroom, the upper end of the vertical wall surface is formed at a position higher than the position where it is in contact with the drainage edge in the water conveyance path portion, so that the water accumulated in the water conveyance path portion is naturally generated. And it will gather from the upper end of the standing wall to the drainage edge. As a result, the height of the water collected in the vicinity of the drainage edge portion of the headrace passage portion can be easily set to be higher than the lower end of the groove portion. Therefore, the water accumulated in the groove portion can be connected to the water accumulated on the water conveyance path portion without interruption.

A fourth aspect of the present invention is the bathroom washroom floor, wherein in the first aspect, the drainage connection means has a surface of the water conveyance path portion having a higher water repellency than the surface of the washroom floor main body. ..

According to the washroom floor of this bathroom, the surface of the water conveyance path portion has a higher water repellency than the surface of the washroom floor body, so that the contact angle of the water collected in the water conveyance path portion becomes large, and the water guide path portion becomes It becomes easier to make the height of the accumulated water higher than the lower end of the groove. Therefore, the water accumulated in the groove portion can be connected to the water accumulated on the water conveyance path portion without interruption.

In the fifth aspect of the invention, in any one of the first to fourth aspects, the curvature of the position where the upper end of the notch portion on the water guide path side side and the water guide path portion are connected is the curvature of the washing place of the notch portion. It is a bathroom washroom floor characterized by being larger than the curvature of the upper end on the floor body side.

According to the washing floor of this bathroom, the water collected in the water conveyance path easily flows from the position of the notch on the washing floor main body side, not from the position near the standing wall surface in the notch, so that the water conducting path The water accumulated in the part can be collected and flowed down from the notch.

As shown in FIGS. 1 to 5, the bathroom 100 according to the embodiment of the present invention includes a bathtub 1 that allows bathers to take a bath by storing hot water, a washing floor 3 that allows bathers to walk, and a bather. An entrance door (not shown) that allows you to enter the room, a bathroom wall (not shown) that surrounds all four sides of the bathroom space, and a bathroom ceiling (not shown) that is connected to the top of the bathroom wall. , Is equipped.

The washing place floor 3 includes a washing place floor main body 2 and a drainage pit 14. The washing floor main body 2 has a base portion 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 surfaces of the convex portion 6 and the concave portion 8 are hydrophilized. 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 portion 6 and the concave portion 8 with the hydrophilic paint, polka dot-like residual water is less likely to be generated on the surface of the surface of the convex portion 6 and the concave portion 8. Specific examples of the hydrophilic coating material include hydrophilicity such as -OH, -O-, -NHCO-, -CONH2, -COOH, -SO3H, -OPO (OH) 2, -NH2, -NH-, and -NR2. Examples thereof include hydrophilic paints composed of a polymer having a sex group and a solvent. The washing floor 3 may be formed so that the contact angle of the water droplets adhering to the surfaces of the convex portion 6 and the concave portion 8 is, for example, 40 degrees or less, more preferably 25 degrees or less.

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

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

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

The surface of the washing place floor body 2, for example, the surfaces of the convex portion 6 and the concave portion 8 is inclined toward the drainage 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 toward the drainage pit 14, that is, toward the drainage edge portion 10 without interruption. At this time, as described above, since the surfaces of the convex portion 6 and the concave portion 8 are hydrophilized, the water adhering to the surface of the convex portion 6 easily spreads, and the spread water is combined with the water accumulated in the concave portion 8. By doing so, the water adhering to the surface of the convex portion 6 can easily flow toward the drainage edge portion 10 without interruption.

The water guide path portion 18 has a drainage connection means for suppressing the water accumulated in the recess 8 from being interrupted with respect to the water collected on the water guide path portion 18. This drainage connection means will be described in detail later.

The cutout portion 20 has a surface tension increasing means for increasing the surface tension generated in the water that has entered the cutout portion 20 to be larger than the surface tension generated in the water accumulated in the recess 8. The surface tension increasing means will be described in detail later.

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

As shown in FIG. 6, the distance X1 from the upper end of the vertical wall portion 16 to the drainage edge portion 10 (distance X1 from the upper end of the vertical wall portion 16 to the base 4) in the water conveyance path portion 18 is the lower end of the washing place floor main body 2. It is larger than the distance Y from the to the lower end of the recess 8. In other words, the length X1 in the width direction of the water conveyance 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 collected in the water conveyance path portion 18 can be easily made higher than the lower end of the recess 8.
If the distance from the upper end of the vertical wall surface to the drainage edge in the water conveyance path is smaller than the distance from the lower end to the lower end of the recess in the floor body of the washing place, the height of the water collected in the water conveyance path is the height of the recess. Before it grows higher than the lower end, it runs down from the vertical wall. In such a washing place floor, the water accumulated in the concave portion and the water accumulated on the water conveyance path portion 18 are not connected, and the water accumulated in the concave portion does not properly flow to the drain port and stagnates.
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 vertical wall surface portion 16 in the water conveyance path portion 18 to the drainage edge portion 10 is from the lower end of the washing place floor main body 2 to the lower end of the recess 8. Since the distance is larger than Y, the water accumulated in the recess 8 can be appropriately connected to the water accumulated on the water conveyance path portion 18 so as not to be interrupted.
Therefore, the distance X1 from the upper end of the vertical wall surface portion 16 to the drainage edge portion 10 in the water conveyance 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 place floor main body 2. There is one.
The distance X2 from the position where R of the upper end of the vertical wall portion 16 of the water conveyance path portion 18 starts to the drainage edge portion 10 may be made larger than the distance Y from the lower end of the washing place floor body 2 to the lower end of the recess 8. , More preferred.

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

As shown in FIG. 7, for example, in the water conveyance path portion 18, the upper end of the vertical wall surface portion 16 may be formed at a position higher than the position where it is in contact with the drainage edge portion 10. As a result, the water collected in the headrace passage portion 18 naturally collects from the upper end of the vertical wall surface portion 16 to the drainage edge portion 10. This makes it easier for the height of the water collected in the vicinity of the drainage edge portion 10 of the water conveyance path portion 18 to be higher than the lower end of the recess 8. Therefore, the water accumulated in the recess 8 can be appropriately connected to the water accumulated on the water conveyance path portion 18 so as not to be interrupted.
Therefore, in the water conveyance path portion 18, forming the upper end of the vertical wall surface portion 16 at a position higher than the position where it is in contact with the drainage edge portion 10 is also one of the drainage connection means.

More preferably, the water conveyance path portion 18 may form an inclined surface that inclines from the upper end of the vertical wall surface portion 16 toward the position in contact with the drainage edge portion 10. As a result, the water collected in the headrace passage portion 18 is collected from the upper end of the vertical wall surface portion 16 to the drainage edge portion 10.

The depth of the notch 20 is larger than the depth of the recess 8. As a result, 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 in the water conveyance path portion 18. Water can be discharged by the notch portion 20 formed in the vertical wall portion 16 so as to be connected to the water conveyance path portion 18 in the connected state. The depth of the cutout portion 20 is preferably 1.0 mm or more.
Therefore, making the depth of the notch 20 larger than the depth of the recess 8 is one of the means for increasing the surface tension.

The width of the notch 20 is smaller than the width of the recess 8. As a result, 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 in the water conveyance path portion 18. Water can be discharged by the notch portion 20 formed in the vertical wall portion 16 so as to be connected to the water conveyance path portion 18 in the connected state. The width of the cutout portion 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 also one of the means for increasing the surface tension.

The surface roughness of the notch 20 is larger than the surface roughness of the recess 8. As a result, 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 in the water conveyance path portion 18. Water can be discharged by the notch portion 20 formed in the vertical wall portion 16 so as to be connected to the water conveyance path portion 18 in the connected state.
Therefore, making the surface roughness of the notch portion 20 larger than the surface roughness of the recess 8 is also one of the means for increasing the surface tension.

8 and 9 are schematic partial perspective views showing the flow of drainage in the washing floor of FIG. 2.
FIG. 10 is a schematic partial cross-sectional view showing a notched portion of the drainage pit in the washing floor of FIG. 2.
It should be noted that FIG. 8 is a schematic partial perspective view showing the flow of drainage in the washing floor of FIG. 2 in the initial state in which the residual water of the washing floor is discharged, and FIG. 9 is a schematic partial perspective view showing the flow of drainage in the washing floor. It is a schematic partial perspective view which shows the flow of the drainage in the washing place floor of FIG. 2 in the final state where the residual water is discharged. In FIGS. 8 and 9, the arrows represent virtual water flows.

As described above, the surfaces of the convex portion 6 and the concave portion 8 are hydrophilized, 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 collected 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 this drainage gradient (inclination angle) is very gentle as described above, the water collected on the surface of the recess 8 slowly flows to the drainage edge portion 10.

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

Further, by the above-mentioned surface tension increasing means, the surface tension acting on the water in the notch 20 becomes larger than the surface tension acting on the water accumulated on the surface of the washing place floor body 2, so that the surface tension is accumulated on the surface of the washing place floor body 2. Even when tension occurs between the water and the water in the notch 20 via the water accumulated on the surface of the headrace path 18, the flow of water in the notch 20 causes the washroom floor. The water accumulated on the surface of the main body 2 and the water accumulated on the surface of the headrace passage portion 18 can be firmly drawn into the notch portion 20.

At this time, since water can be strongly discharged by the surface tension increasing means, if the number of the cutouts 20 is large, the amount of water flowing down from the cutouts 20 becomes too large, and the water conveyance path. There is a possibility that the 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 floor 3 according to the embodiment of the present invention, as shown in FIGS. 2 and 5, the number of notches 20 is smaller than the number of recesses 8 connected to the water conveyance path portion 18. In other words, the number of cutouts 20 is smaller than the number of openings 22 connected to the recesses 8 provided in the drainage edge 10. As a result, even when water is strongly discharged by the surface tension increasing means, it is possible to prevent the water accumulated on the surface of the water conveyance path portion 18 from being discharged at once and the water being interrupted.

As shown in FIG. 9, especially when the residual water on the washing floor 3 is low, the notch 20 is not from a position close to the vertical wall surface 16, but is on the washing floor main body 2 side of 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 of the notch 20 on the water guide path 18 side and the water guide 18 are connected is the curvature of the notch 20 on the washroom floor body 2 side. This is because it is larger than the curvature of the curved surface 24 which is the upper end. That is, the upper end 23 of the notch portion 20 on the water conveyance path portion 18 side is formed sharper than the upper end of the notch portion 20 on the washroom floor main body 2 side. As a result, when the amount of water accumulated in the water conveyance path portion 18 is reduced, the water accumulated in the water conveyance path portion 18 falls from the upper end 23 of the notch portion 20 on the water conveyance path portion 18 side to the notch portion 20. On the other hand, the water flowing down from the upper end of the notch 20 on the floor body 2 side to the notch 20 relatively slowly along the curved surface 24 having a small curvature, and the water conduction path of the notch 20 It becomes easy to combine with the water of the water conveyance path portion 18 accumulated in the upper end 23 on the 18 side. Therefore, especially when the residual water on the washing floor 3 is low, it becomes easier to flow from the position of the notch 20 near the standing wall surface 16 but from the position of the notch 20 on the washing floor body 2 side. .. From this, especially when the residual water on the washing place floor 3 becomes small, the water accumulated in the water conveyance path portion 18 can be collectively flowed down from the notch portion 20.

As shown in FIG. 10, there is a semi-concealed space between the lower end surface of the washroom floor body 2 (lower end surface of the base 4) and the curved surface 24 which is the upper end of the notch 20 on the washroom floor body 2 side. Is formed. As a result, the magnitude of the surface tension acting on the water that has entered the gap at the upper end of the washing place floor body 2 side of the notch portion 20 can be locally increased, and is close to the standing wall surface portion 16 of the notch portion 20. It becomes easier to flow from the position on the washing place floor main body 2 side in the notch 20 rather than from the position. From this, especially when the residual water on the washing place floor 3 becomes small, the water accumulated in the water conveyance path portion 18 can be collected and flowed down from the cutout portion 20.
