Description

  The present invention relates to bathroom floors.

  BACKGROUND ART Conventionally, as a bathroom floor of this type, one disclosed in Patent Document 1 is known. In Patent Literature 1, the bathroom floor has 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 greater than 0 and 5 μm or less. It is described that with such a configuration, the attraction force due to the capillary phenomenon of the groove can be enhanced to improve drainage of the entire floor surface.

JP-A-2004-291443

  However, in the bathroom floor of Patent Literature 1, the drainage of the entire floor surface is not always sufficient, and a further improvement in performance is required at present.

  The present invention has been made in view of the above-mentioned conventional circumstances, and has as its object to provide a bathroom floor with a good drainage flow.

The bathroom floor of the present invention is a bathroom floor divided into a plurality of areas by a groove,
The area is a decorative surface with irregularities,
With reference to the highest portion of the decorative surface, 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, the deepest depth of the concave portion of the decorative surface and the depth of the groove are substantially the same with respect to the highest portion of the decorative surface, so that the following effects are obtained. In a typical bathroom floor, the depth of the groove is made deeper than the concave portion on the decorative surface. Therefore, in such a bathroom floor, drainage tends to collect in the ditch, and flows along the ditch. On the other hand, in the bathroom floor of the present invention, the depth of the groove is substantially the same as the deepest depth of the concave portion of the decorative surface, so that the drainage does not necessarily collect in the groove, but also flows on the decorative surface. Become. Therefore, in the case of the present invention, the portion that contributes to drainage is a groove and a decorative surface, so that drainage efficiency is high.

It is a perspective view showing the bathroom where 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. It is a top view which shows the bathroom floor of Example 1. It is a perspective sectional view showing the bathroom floor of Example 1. It is sectional drawing which shows the bathroom floor of Example 1. It is sectional drawing which shows the bathroom floor of the 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 spreads toward the front side. On a general bathroom floor, the cross-sectional shape of the groove is substantially rectangular. In such a groove, dirt easily accumulates at both corners of the bottom surface of the groove. In addition, even when cleaning, it is difficult for cleaning tools such as brushes to reach both corners, and it is difficult to clean. 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. Further, even in the case of cleaning, a cleaning tool such as a brush is easy to enter and cleaning is easy.

  Next, Embodiment 1 in which the bathroom floor 1 of the present invention is embodied will be described with reference to the 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 section 9 whose upper surface is opened in a substantially square shape over the entire area, and is substantially horizontal outward from the opening edge of the upper surface (upper end) of the hot water storage section 9 over the entire circumference. And a flange portion 11 which is formed in a single piece. Hot water storage section 9 includes a bottom wall 13 that is substantially rectangular and long in the front-rear direction. A drain groove 15 is formed at a position near the bathroom floor 1 on the bottom wall portion 13, and the bottom wall portion 13 has a gentle slope toward the drain groove 15 so that water flows toward the drain groove 15. Have.

  Hot water storage section 9 includes a pair of side wall sections 17 rising diagonally upward and outward from both side edges of bottom wall section 13, a front wall section 19 rising diagonally upward and forward from the front edge of bottom wall section 13, and a bottom wall section. 13 and a rear wall portion 21 rising obliquely upward and rearward from the rear edge portion. Each of the portions where the wall portions 17, 19, and 21 are connected has a smooth curved surface. A plurality of anti-slip projections 23 are formed on the bottom wall 13. The protrusions 23 are arranged in a staggered arrangement. The shape of each projection 23 is substantially rectangular in plan view. This shape belongs to the same class as the shape of the area 49 described later. The shape is classified into a substantially rectangular shape, a substantially triangular shape, a substantially round shape, and the like. In the present embodiment, the shape of the projection 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 gentle curved surface such that the approximate center is slightly recessed toward the bathtub body 5, and is configured separately from the bathtub body 5. Near the rear end of the apron 7 and near the lower end of the apron 7, a substantially rectangular shelf 27 projecting toward the near side is formed. A container such as a shampoo or a rinse can be placed on the shelf 27. The shelf 27 has a rounded corner on the protruding side. A substantially rectangular openable and closable door 29 is provided in a portion where the shelf 27 is formed, and the door 29 can be opened to perform work such as inspection.

  The bathroom floor 1 is formed in a shallow pan shape as a whole. As shown in FIGS. 1 to 3, the bathroom floor 1 is substantially rectangular in plan view, and has a curved shape such that only one side of the apron 7 is expanded. The bathroom floor 1 has 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 falling into the drain port 31 and ensures drainage. The outermost edge of the bathroom floor 1 is a water return wall 37 that rises upward and is formed.

The bathroom floor 1 is provided with a drainage gradient so that the drainage port 31 is the lowest. The water flows along the drain gradient and is collected at the drain 31. On the surface, as shown in FIG. 2, three slope surfaces 39, 41, and 43, each having a different drainage direction, are formed. Each of the slopes 39, 41, 43 is inclined downward toward the drain 31. A ridgeline 45 formed as a valley is formed between the slope surface 39 and the slope surface 41. A ridge line 47 formed as a valley is formed between the slope surface 41 and the slope surface 43. However, these ridgelines 45 and 47 are made inconspicuous so as not to impair the design of the bathroom floor 1. Therefore, the ridges 45 and 47 have no ridges or grooves 25.
The water in the bathroom floor 1 flows on the slopes 39, 41, 43 toward the drain 31.

  The bathroom floor 1 is divided into a plurality of areas 49 by grooves 25, as shown in FIG. Specifically, as shown in FIGS. 1 to 3, for example, as shown in FIGS. Has been.

  The design consisting of the plurality of areas 49 of the bathroom floor 1 is considered as follows. In other words, 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 in accordance with the frame of the size of the washing area. Accordingly, in this case, each area 49 corresponding to the outer peripheral portion of the bathroom floor 1 has 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 a portion of the bathroom floor 1 adjacent to the bathtub 3, a substantially rectangular shape is missing along the arc shape of the apron 7. ing. In other words, 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. Also, the area of each of these areas 49A is smaller than the area of the area 49B that is not missing.

  In general, even in an area 49 located in a portion of the bathroom floor 1 adjacent to the bathtub 3, in a mode in which the substantially rectangular shape of the area 49 is not missing at all, the bathroom floor 1 is separated from the bathtub 3. I feel like I'm doing it. On the other hand, in the present embodiment, as shown in FIG. 3, each of the areas 49 </ b> A located in the portion of the bathroom floor 1 adjacent to the bathtub 3 has a shape lacking a substantially rectangular shape. By doing so, the unity of the bathroom floor 1 and the bathtub 3 is created. Therefore, even under the bathtub 3, the user can feel as if the bathroom floor 1 is as if he were, and the space can be expanded. As described above, in this embodiment, the space is designed so that the space can be felt large.

  Further, in this embodiment, an area 49 </ b> C having a substantially rectangular shape is present in a place not adjacent to the bathtub 3 on the bathroom floor 1. That is, the area 49C in FIG. 3 has a shape in which the longer side of the substantially rectangle is chipped so as to be shorter. The area of each of these areas 49C is smaller than the area of the area 49B which is not missing.

  In a mode in which the substantially rectangular shape of the area 49 that is the outer peripheral portion of the bathroom floor 1 and is not adjacent to the bathtub 3 of the bathroom floor 1 is completely missing, the bathroom floor 1 extends outside the actual area. I don't feel like it is. On the other hand, in the present embodiment, as shown in FIG. 3, the area 49C lacks a substantially rectangular shape. In this way, the user can be made to feel as if the washing place is as if the washing room is over the actual bathroom floor 1, and the space can be expanded. As described above, in this embodiment, the space is designed so that the space can be felt large.

As shown in FIG. 4, the area 49 divided by the groove 25 is a decorative surface 51 having an uneven top surface. The unevenness of the decorative surface 51 is designed in consideration of designability and slipperiness, and a regular pattern, 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 the same. 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, _{D 1} and _{D 2} together, 0.5～0.9Mm, preferably, 0.6 to 0.8 mm, more preferably from 0.7 mm. Thus, setting the D ₁ and D _2, and the waste water is not necessarily collect in the groove 25, so that will be flowing over the decorative surface 51. Therefore, the portion that contributes to the drainage is the groove 25 and the decorative surface 51, and the drainage efficiency is increased. This technical idea is fundamentally different from the conventional technical idea of draining mainly around the groove 25.

Here, this embodiment will be described in more detail in comparison with the conventional bathroom floor 1. FIG. 6 shows a 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, it is assumed that D ₂ > D ₁ . Therefore, in this structure, water was easily flowed into the lower groove 25. Therefore, the portion contributing to the drainage is mainly the groove 25 portion. That is, flowing water on the decorative surface 51 has not been considered much. 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 one, the cross-sectional area of the groove 25 is designed to be larger than the cross-sectional area of each concave portion 53 of the decorative surface 51. The conventional technical idea is to drain the water around the groove 25, which 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 expands toward the front side, and has a substantially U-shape with an enlarged opening as a whole. The bottom of the groove 25 has a curved surface, has no corners, and has a shape in which dirt hardly accumulates. Regarding 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. Therefore, the groove 25 has a sharper shape directed downward. Thereby, the groove 25 is more clearly seen than the pattern due to the unevenness of the decorative surface 51, and the division of the area 49 by the groove 25 is made visible to the user.

  The cross-sectional shape of the groove 25 of the conventional example is substantially rectangular as shown in FIG. In detail, it has a flat bottom portion 25A and a side wall portion 25B rising from the bottom portion 25A, and the bottom portion 25A has a form in which there are two corner portions 25C that are substantially right angles in cross section. . For this reason, in the groove 25 of the conventional example, there is a tendency that dirt easily accumulates at a substantially right-angled corner 25C. The corner 25C is a place where it is difficult for cleaning tools such as brushes to reach even when cleaning.

In this embodiment, the opening width W ₁ of the recess 53 in the unevenness of the decorative surface 51 is different 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. Then, the opening width _{W 2} of the groove 25 is set smaller than the opening width _{W 1} of the recess 53 of the decorative surface 51. The opening width W ₁ of the recess 53 in this way the decorative surface 51, by setting the opening width W ₂ of the groove 25, the groove 25 becomes more noticeable than the unevenness of the decorative surface 51, the groove 25 is a pseudo Plays the role of joint and is advantageous in 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 solution, a chemical polishing solution for steel and an iron perchlorate solution can be used alone or in combination. Water, nitric acid, hydrochloric acid and the like can be blended with these and used. The bathroom floor 1 of this embodiment can also be manufactured by a mold manufactured using only the etching process.

<Effects of the embodiment>
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 they are substantially the same, the following operation and effect can be obtained. In the conventional bathroom floor 1, the depth of the groove 25 is made deeper than the concave portion 53 of the decorative surface 51. Therefore, in such a bathroom floor 1, drainage tends to collect 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 , Also flows on the decorative surface 51. Accordingly, in the case of the present embodiment, the drainage efficiency is increased because the portion that contributes to the 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 expands toward the front side, and has a substantially U-shape with a wide opening. In the conventional bathroom floor 1, the cross-sectional shape of the groove 25 is substantially rectangular as shown in FIG. In detail, it has a flat bottom portion 25A and a side wall portion 25B rising from the bottom portion 25A, and the bottom portion 25A has a form having two substantially right-angled corner portions 25C when viewed in cross section. . In such a conventional groove 25, dirt easily accumulates at both corners 25C of the bottom surface. Also, in the case of cleaning, it is difficult for cleaning tools such as brushes to reach both corners 25C, and it is difficult to clean. On the other hand, in the bathroom floor 1 of the present embodiment, since the cross-sectional shape of the groove 25 is widened toward the front side, dirt is less likely to accumulate than the general bathroom floor 1. Further, even in the case of cleaning, a cleaning tool such as a brush is easy to enter and cleaning is easy.

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 visible to the user, and plays a role of a pseudo joint.
Also, the opening width W ₂ of the groove 25 is set smaller than the opening width W ₁ of each recess 53 of the decorative surface 51. The opening width W ₁ of the recess 53 in this way the decorative surface 51, by setting the opening width W ₂ of the groove 25, with strong shading in the groove 25 becomes more noticeable than the unevenness of the decorative surface 51, a groove 25 serves as a pseudo joint and is advantageous in design. In this 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 this embodiment, the opening width W ₂ of the groove 25, from being set narrower than the opening width W ₁ of the recess 53 of the decorative surface 51, the gradient of the downslope to form the groove 25, the recess of the decorative surface 51 It becomes larger than the slope of the descending slope of 53. 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 this embodiment can sufficiently fulfill 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 defined by the groove 25 belong to the same class. Here, the shapes belonging to the same category include, as a shape classification, a substantially rectangular shape, a substantially triangular shape, a substantially round shape, and the like. In this embodiment, the planar shape of the bathtub 3 and the area 49 defined by the groove 25 are used. Are both substantially rectangular. The following effects can be expected when the planar shape of the bathtub 3 and the divided area 49 are formed to belong to the same category. That is, humans are more likely to receive a sense of security if 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 a sense of security is easily obtained. In particular, since the bath is in a relaxed state and the tension is easily relieved, if the shape of the bath tub 3 and the area 49 belong to the same category, a synergistic effect with the bathing is expected to provide a high level of security. it can.

  Further, in the present embodiment, the shape of the non-slip protrusion 23 and the shape of the area 49 defined by the groove 25 belong to the same class. In the present embodiment, the area 49 defined by the anti-slip protrusion 23 and the groove 25 is both substantially rectangular. The following effects can be expected when the planar shape of the anti-slip protruding portion 23 and the divided area 49 have a shape belonging to the same class. That is, humans are more likely to receive a sense of security if they are in a space where a plurality of shapes belonging to the same category are arranged. In the bathroom floor 1 according to the present embodiment, shapes belonging to substantially the same category are also arranged in the bathtub 3, so that a sense of security can be easily obtained. In particular, since the person is in a relaxed state during bathing and the tension is easily relieved, if the shape of the anti-slip protruding part 23 and the area 49 is a shape belonging to the same class, a high sense of security is obtained due to a synergistic effect with bathing. The expected effect can be expected.
