Description

  The present invention relates to a bathroom floor.

  Conventionally, what was disclosed by patent document 1 as this kind of bathroom floor is known. In Patent Document 1, the bathroom floor includes a plurality of grooves and a raised body formed at a position surrounded by the grooves on the surface. The bottom surface of the groove has a center line surface roughness Ra of 10 to 100 μm, while the surface of the raised body has a center line surface roughness Ra of more than 0 and 5 μm or less. If comprised in this way, it is supposed that the attraction force by the capillary phenomenon of a groove | channel can be strengthened and the drainage property of the whole floor surface can be improved.

JP 2004-291443 A

  However, in the bathroom floor of this patent document 1, the drainage of the whole floor surface is not necessarily sufficient, and the present condition is that the improvement of the further performance is calculated | required.

  This invention is made | formed in view of the said conventional situation, Comprising: It aims at providing the bathroom floor with a favorable flow of waste_water | drain.

The bathroom floor of the present invention is a bathroom floor divided into a plurality of areas by grooves,
The area is an uneven decorative surface,
When the highest part of the decorative surface is used as a reference, the deepest depth of the concave portion of the decorative surface and the depth of the groove are substantially the same.

  In the bathroom floor according to the present invention, when the highest part of the decorative surface is used as a reference, the deepest depth of the concave portion of the decorative surface and the depth of the groove are substantially the same, and therefore, the following effects are obtained. In a general bathroom floor, the depth of the groove is deeper than the recess of the decorative surface. Therefore, in such a bathroom floor, the drainage easily collects in the groove and flows along the groove. On the other hand, in the bathroom floor of the present invention, since the depth of the groove is substantially the same as the deepest depth of the concave portion of the decorative surface, the drainage does not necessarily collect in the groove, but also flows on the decorative surface. Become. Accordingly, in the case of the present invention, the drainage efficiency is high because the portion contributing to drainage becomes the groove and the decorative surface.

It is a perspective view which shows the bathroom in which the bathroom floor of Example 1 was installed. It is a top view which shows the bathroom in which the bathroom floor of Example 1 was installed. 3 is a plan view showing a bathroom floor of Example 1. FIG. 1 is a perspective sectional view showing a bathroom floor of Example 1. FIG. 3 is a cross-sectional view showing a bathroom floor of Example 1. FIG. It is sectional drawing which shows the bathroom floor of a prior art example.

  A preferred embodiment of the present invention will be described.

  In the bathroom floor of the present invention, the cross-sectional shape of the groove is preferably a shape that widens toward the front side. In a general bathroom floor, the cross-sectional shape of the groove is substantially rectangular. In such a groove, dirt tends to accumulate at both corners of the bottom surface of the groove. Moreover, even when cleaning, cleaning tools such as brushes are difficult to reach at both corners, and cleaning is difficult. On the other hand, in the bathroom floor of the present invention, when the cross-sectional shape of the groove is widened toward the front side, dirt is less likely to accumulate than a general bathroom floor. Furthermore, when cleaning, a cleaning tool such as a brush is easy to enter and easy to clean.

  Next, Example 1 which actualized the bathroom floor 1 of this invention is demonstrated, referring drawings.

<Example 1>
As shown in FIG. 1, the bathroom floor 1 of the first embodiment is integrally formed of FRP (fiber reinforced plastic) or the like, and forms a washing area adjacent to the bathtub 3. The bathtub 3 includes a bathtub main body 5 and an apron 7. The bathtub main body 5 has a box-shaped hot water storage portion 9 whose upper surface is opened in a substantially rectangular shape over the entire region, and is substantially horizontally outward from the opening edge of the upper surface (upper end) of the hot water storage portion 9 over the entire circumference. The flange portion 11 is formed integrally with the flange portion 11 projecting from the top. The hot water storage section 9 includes a bottom wall section 13 having a substantially rectangular shape that is long in the front-rear direction. A drainage groove 15 is formed at a position near the bathroom floor 1 of the bottom wall portion 13, and the bottom wall portion 13 is gently inclined toward the drainage groove 15 so that water flows toward the drainage groove 15. Have.

  The hot water storage portion 9 includes a pair of side wall portions 17 that rise obliquely upward and outward from both side edge portions of the bottom wall portion 13, a front wall portion 19 that rises obliquely upward and forward from the front edge portion of the bottom wall portion 13, and a bottom wall portion 13 and a rear wall portion 21 rising obliquely upward and rearward from the rear edge portion. All of the portions where these wall portions 17, 19, and 21 are connected are formed with smooth curved surfaces. A plurality of anti-slip protrusions 23 are formed on the bottom wall 13. The protrusions 23 are arranged in a staggered arrangement. Each protrusion 23 has a substantially rectangular shape in plan view. This shape is a shape belonging to the same category as the shape of the area 49 described later. The shape classification includes a substantially rectangular shape, a substantially triangular shape, a substantially round shape, and the like. In the present embodiment, the shape of the protrusion 23 and the shape of the area 49 are both substantially rectangular. The upper surface of each projection 23 is a flat surface.

  The apron 7 is provided so as to cover the side surface of the bathtub body 5 on the bathroom floor 1 side. The apron 7 is a wall member that draws a gently curved surface so that the approximate center is slightly recessed toward the bathtub body 5 side, and is configured separately from the bathtub body 5. Near the rear end of the apron 7 and at a position near the lower end of the apron 7, a substantially rectangular shelf 27 protruding to the near side is formed. A container such as shampoo or rinse can be placed on the shelf 27. The shelf 27 has a rounded corner on the protruding side. In the portion where the shelf 27 is formed, a substantially rectangular door 29 that can be opened and closed is provided, and the door 29 can be opened to perform operations such as inspection.

  The bathroom floor 1 is formed in a shallow bread shape as a whole. As shown in FIGS. 1 to 3, the bathroom floor 1 has a substantially rectangular shape in plan view, and has a curved shape such that only one side of the apron 7 swells. The bathroom floor 1 includes a drain port 31 and a surface that is inclined downward toward the drain port 31. The drain port 31 is formed at a position close to the bathtub 3, and the drain port 31 is covered with a rectangular cover member 35 while securing a water channel. The cover member 35 prevents a large object from dropping into the drain port 31 and ensures drainage. The outermost edge portion of the bathroom floor 1 is a water return wall portion 37 formed upward.

The bathroom floor 1 has a drainage gradient so that the drainage port 31 is lowest. The water flows along the drainage gradient and is collected at the drainage port 31. As shown in FIG. 2, three slope surfaces 39, 41, and 43 having different drainage directions are formed on the surface. Each of the slope surfaces 39, 41, 43 is inclined downward toward the drain port 31. Between the slope surface 39 and the slope surface 41, a ridge line 45 formed as a valley is formed. A ridge line 47 formed as a valley is formed between the gradient surface 41 and the gradient surface 43. However, these ridge lines 45 and 47 are made inconspicuous so as not to impair the design of the bathroom floor 1. Accordingly, the ridges 45 and 47 are not formed with protrusions or grooves 25.
The water on the bathroom floor 1 flows toward the drain port 31 on each of the slope surfaces 39, 41, 43.

  As shown in FIG. 1, the bathroom floor 1 is divided into a plurality of areas 49 by grooves 25. Specifically, as shown in FIGS. 1 to 3, the entire area of the washing area where the bathroom floor 1 is arranged is, for example, a substantially rectangular area 49 that is half-shifted from the lower area 49 (horse loading). Has been.

  The design composed of a plurality of areas 49 of the bathroom floor 1 is considered as follows. That is, first, for example, a horse stack in which areas 49 having substantially the same shape are stacked is imagined. Then, a part of the image is cut out from the image according to the frame of the size of the washing area. Therefore, in this case, each area 49 corresponding to the outer peripheral portion of the bathroom floor 1 is in a form in which a shape such as a substantially rectangular shape is partially missing, as shown in FIG. Specifically, as shown in FIG. 3, in each area 49 </ b> A located in the portion adjacent to the bathtub 3 of the bathroom floor 1, a substantially rectangular shape is missing along the arc shape of the apron 7. ing. That is, each of the three areas 49A in FIG. 3 has a shape in which one side of a substantially rectangular shape facing the apron 7 is rounded in an arc shape. Further, the area of each area 49A is smaller than the area of the non-missing area 49B.

  In general, even if the area 49 is located in a portion adjacent to the bathtub 3 of the bathroom floor 1, the bathroom floor 1 is separated from the bathtub 3 in a mode in which the substantially rectangular shape of the area 49 is not lost at all. It feels like On the other hand, in this embodiment, as shown in FIG. 3, each area 49 </ b> A located in the portion adjacent to the bathtub 3 of the bathroom floor 1 has a substantially rectangular shape lacking. If it does in this way, unity of bathroom floor 1 and bathtub 3 will be born. Therefore, it is possible to make the user feel the bathroom floor 1 as if it is under the bathtub 3 and to create a space. As described above, the present embodiment is devised so that a large space can be felt in terms of design.

  In this embodiment, an area 49C lacking a substantially rectangular shape is present at a location not adjacent to the bathtub 3 on the bathroom floor 1. That is, the area 49 </ b> C in FIG. 3 has a shape lacking so that the long side of the substantially rectangular shape is shortened. The area of each of these areas 49C is made smaller than the area of the non-missing area 49B.

  In an aspect in which the substantially rectangular shape of the area 49 corresponding to the outer peripheral portion of the bathroom floor 1 and not adjacent to the bathtub 3 of the bathroom floor 1 is not missing at all, the bathroom floor 1 extends outside the actual region. I can't feel it. On the other hand, in this embodiment, as shown in FIG. 3, the area 49C lacks a substantially rectangular shape. If it does in this way, it can make a user feel as if the washing place is completely beyond the actual bathroom floor 1, and can produce the expansion of space. As described above, the present embodiment is devised so that a large space can be felt in terms of design.

As shown in FIG. 4, the area 49 divided by the grooves 25 is a decorative surface 51 having an uneven upper surface. The unevenness of the decorative surface 51 is designed in consideration of design and slipperiness, and a pattern having regularity, a random pattern, a combination thereof, and the like can be arbitrarily selected. In this embodiment, as shown in FIG. 5, when relative to the highest part 51A of the decorative surface 51, a deepest depth D ₁ of the recess 53 of the decorative surface 51, the depth D ₂ of the groove 25 Are substantially identical. This relationship is schematically shown in FIG. As shown in FIG. 5, from the highest portion 51A of the decorative surface 51, a deepest depth of the concave portion 53 of the decorative surface 51 and _{D 1,} represents the depth of the grooves 25 and _{D 2.} In this embodiment, D ₁ and D ₂ are substantially the same. That is, D ₁ ≈D ₂ . Preferably, _{D 2} is a 100 to 110% of _{D 1.} For example, specifically, both D ₁ and D ₂ are 0.5 to 0.9 mm, preferably 0.6 to 0.8 mm, and more preferably 0.7 mm. Thus, when D ₁ and D ₂ are set, the drainage does not necessarily collect in the groove 25 but also flows on the decorative surface 51. Therefore, since the part which contributes to drainage becomes the groove | channel 25 and the decorative surface 51, drainage efficiency becomes high. This technical idea is fundamentally different from the conventional technical idea of draining around the groove 25.

Here, this example will be described in more detail in comparison with the conventional bathroom floor 1. FIG. 6 shows a cross-sectional view of a conventional bathroom floor 1. As shown in FIG. 6, the depth of the recess 53 from the highest portion 51A of the decorative surface 51 and D _1. On the other hand, the depth of the groove 25, and _{D 2.} In the conventional example, D ₂ > D ₁ is satisfied. Therefore, in this thing, water was made easy to flow into the portion of the lower groove 25. Therefore, the portion contributing to drainage is mainly the portion of the groove 25. That is, it has not been considered much that water flows on the decorative surface 51. Further, the conventional, well depth of the grooves 25 are wider than the opening width W ₁ of the opening width W ₂ also recesses 53 (see FIG. 6). Thus, in the conventional device, the cross-sectional area of the groove 25 is designed to be larger than the cross-sectional area of each recess 53 of the decorative surface 51. The conventional technical idea drains around the groove 25, and is fundamentally different from the technical idea of the present embodiment.

The groove 25 will be described in more detail. In the present embodiment, as shown in FIG. 5, the cross-sectional shape of the groove 25 is a shape that widens toward the front side, and as a whole, has a substantially U-shape in which the opening is widened. The bottom of the groove 25 has a curved surface, has no corners, and has a shape in which dirt does not accumulate easily. Concerning the shape, the concave portion 53 of the decorative surface 51 and the groove 25 are compared. The opening width W ₁ of the recess 53 of the decorative surface 51, while being larger than the opening width W ₂ of the groove 25, the depth is substantially the same as described above. Accordingly, the groove 25 has a sharper shape toward the lower side. As a result, the groove 25 can be seen more clearly than the pattern formed by the unevenness of the decorative surface 51, and the section of the area 49 by the groove 25 can be visually recognized by the user.

  The cross-sectional shape of the groove 25 of the conventional example is substantially rectangular as shown in FIG. Specifically, it has a flat bottom surface portion 25A and a side wall portion 25B that rises from the bottom surface portion 25A, and the bottom surface portion 25A has two corner portions 25C that are substantially perpendicular to each other in sectional view. . For this reason, in the groove 25 of the conventional example, there is a tendency that dirt is likely to be accumulated in the corner portion 25 </ b> C having a substantially right angle. The corner 25C is a place where a cleaning tool such as a brush is difficult to reach even when cleaning.

In the present embodiment, the opening width W ₁ of the concave portion 53 in the unevenness of the decorative surface 51 varies depending on the formation place and is random. On the other hand, the opening width W ₂ of the groove 25, regardless of the formation location and is substantially the same. The opening width W ₂ of the groove 25 is set to be narrower than the opening width W ₁ of the recess 53 of the decorative surface 51. Thus, by setting the opening width W ₁ of the concave portion 53 of the decorative surface 51 and the opening width W ₂ of the groove 25, the groove 25 becomes more conspicuous than the unevenness of the decorative surface 51, and the groove 25 is pseudo. It plays a role of joint and is advantageous in terms of design.

  The bathroom floor 1 according to the embodiment can be manufactured using a mold obtained by etching a metal plate. Here, as the etching treatment liquid, a chemical polishing liquid for steel and an iron perchloride liquid can be used alone or in combination. These can also be used by blending water, nitric acid, hydrochloric acid or the like. The bathroom floor 1 of the present embodiment can be manufactured by a molding die manufactured using only an etching process.

<Effect of Example>
Bathroom floor 1 according to the present embodiment, when relative to the highest part 51A of the decorative surface 51, a deepest depth D ₁ of the recess 53 of the decorative surface 51, the depth D ₂ of the groove 25, Since it is substantially the same, the following effects are exhibited. In the conventional bathroom floor 1, the depth of the groove 25 is deeper than the recess 53 of the decorative surface 51. Therefore, in such a bathroom floor 1, the drainage easily collects in the groove 25 and flows along the groove 25. On the other hand, in the bathroom floor 1 of the present embodiment, the depth D ₂ of the groove 25, because it is substantially the same as the deepest depth D ₁ of the recess 53 of the decorative surface 51, waste water is not necessarily collect in the groove 25 , It will also flow on the decorative surface 51. Therefore, in the case of the present embodiment, the drainage efficiency is increased because the portion contributing to drainage is the groove 25 and the decorative surface 51.

  In the bathroom floor 1 of the present embodiment, as shown in FIG. 5, the cross-sectional shape of the groove 25 is a shape that widens toward the front side, and as a whole has a substantially U-shape with an open portion. In the conventional bathroom floor 1, the cross-sectional shape of the groove 25 is substantially rectangular as shown in FIG. Specifically, it has a flat bottom surface portion 25A and a side wall portion 25B that rises from the bottom surface portion 25A, and the bottom surface portion 25A has 25C2 corner portions that are substantially perpendicular to each other when viewed in cross section. . Such a conventional groove 25 tends to accumulate dirt at both corners 25C on the bottom surface. Further, even when cleaning is performed, it is difficult for cleaning tools such as brushes to reach both corners 25C, and cleaning is difficult. On the other hand, in the bathroom floor 1 of the present embodiment, since the cross-sectional shape of the groove 25 widens toward the front side, dirt is less likely to accumulate than the general bathroom floor 1. Furthermore, when cleaning, a cleaning tool such as a brush is easy to enter and easy to clean.

The opening width W ₁ of the recess 53 in the unevenness of the decorative surface 51 of this embodiment differs by the formation location is random. On the other hand, the opening width W ₂ of the groove 25, regardless of the formation location and is substantially the same. Therefore, the groove 25 has regularity, is easily perceived by the user's vision, and serves as a pseudo joint.
The opening width W ₂ of the groove 25 is set to be narrower than the opening width W ₁ of each recess 53 of the decorative surface 51. Thus, by setting the opening width W ₁ of the concave portion 53 of the decorative surface 51 and the opening width W ₂ of the groove 25, the groove 25 is strongly shaded and becomes more conspicuous than the unevenness of the decorative surface 51. 25 serves as a pseudo joint and is advantageous in terms of design. In the present embodiment, the depth D ₂ of the groove 25 is substantially the same as the deepest depth D ₁ of the recess 53 of the decorative surface 51. In this case, if the opening width W ₁ of the recess 53 of the decorative surface 51, when the opening width W ₂ of the groove 25 is substantially the same, the groove 25 is less conspicuous to both with the same shade. In the present embodiment, the opening width W ₂ of the groove 25 is set to be narrower than the opening width W ₁ of the concave portion 53 of the decorative surface 51, and therefore the slope of the downward slope forming the groove 25 is the concave portion of the decorative surface 51. It becomes larger than the slope of 53 descending slopes. Therefore, the groove 25 is more likely to be shaded by light and more conspicuous than the concave portion 53 of the decorative surface 51. Therefore, the groove 25 in the present embodiment can sufficiently perform the function of a pseudo joint in terms of design.

  In the present embodiment, the planar shape of the bathtub 3 and the shape of the area 49 partitioned by the groove 25 belong to the same category. Here, the shapes belonging to the same category include a substantially rectangular shape, a substantially triangular shape, a substantially round shape, and the like as the classification of the shape. In this embodiment, the area 49 defined by the planar shape of the bathtub 3 and the groove 25 is used. Are both substantially rectangular. If the planar shape of the bathtub 3 and the partitioned area 49 are shapes belonging to the same category, the following effects can be expected. That is, humans are likely to receive a sense of security when they are in a space where a plurality of shapes belonging to the same category are arranged. A plurality of shapes belonging to substantially the same category are arranged on the bathroom floor 1 of the present embodiment, and it is easy to obtain a sense of security. In particular, it is in a relaxed state during bathing, and the tension is easy to ease. Therefore, if the shape of the bathtub 3 and the area 49 belong to the same category, a synergistic effect with bathing is expected to provide a high sense of security. it can.

  In the present embodiment, the anti-slip protrusion 23 and the shape of the area 49 defined by the groove 25 belong to the same category. In this embodiment, the area 49 defined by the anti-slip projection 23 and the groove 25 is substantially rectangular. The following effects can be expected when the planar shape of the projection part 23 for preventing slip and the partitioned area 49 are shapes belonging to the same category. That is, humans are likely to receive a sense of security when they are in a space where a plurality of shapes belonging to the same category are arranged. In the bathroom floor 1 of the present embodiment, shapes belonging to substantially the same category are also arranged in the bathtub 3 and it is easy to obtain a sense of security. In particular, it is in a relaxed state during bathing, and the tension is easily relieved. Therefore, if the shape of the anti-slip projection 23 and the area 49 belong to the same category, the synergistic effect with bathing provides a high level of security. Expected effects.
