Description

  The present invention relates to a bathroom floor provided with a plurality of convex portions in a washing area.

Conventionally, it has been proposed to form a large number of anti-slip protrusions on a floor surface having a water gradient in order to prevent a fall due to slipping in a bathroom wash area (see, for example, Patent Document 1).
Japanese Patent No. 3508761

  However, as long as the shape and size of the anti-slip convex portions are the same, the upper end surface (walking surface) formed by connecting the upper ends of such convex portions is similarly inclined according to the inclination of the floor surface. To do. Therefore, if the floor surface is steep, there is a sense of incongruity when sitting or standing on the floor, which may make walking difficult. In particular, when the inclination angle is large, there is a possibility that the foot slips when the balance is lost, for example, when soapy water adheres to the upper end of the convex portion.

  Thus, in the bathroom floor provided with the conventional anti-slip projection, the floor surface cannot be steep to improve drainage (drainage), and safety can be ensured. It was customary to use a bathroom floor that was gently inclined at an inclination angle of about 5 degrees.

  In this way, in the conventional one, the floor surface is only slightly inclined, so that a lot of water that is not drained remains on the floor surface after using the bathroom. For this reason, it is hardly possible to evaporate the remaining water on the floor surface by the next morning only by natural drying, and such residual water has been a factor in generating mold and dirt. In particular, when water droplets (polka dots) condensed due to surface tension remain on the floor surface, such water droplets have a small surface area relative to the amount of water, and thus are difficult to evaporate and may remain for a long time without natural drying. It was.

  The present invention has been proposed in view of such circumstances, and its purpose is to provide a bathroom floor that does not feel uncomfortable when sitting or standing on the floor, has a good walking sensation, and can ensure sufficient drainage. It is to provide.

  In order to achieve the above object, the bathroom floor according to claim 1 has a configuration in which a washing area is adjacent to a drainage area including a drain outlet, and a plurality of convex parts and these convex parts are formed on the upper surface of the washing area. A recess is formed in the middle, which separates the projections, and the recess has a downward slope to the drainage area and is continuous to allow water to pass, while the plurality of projections have the same upper surface. It has a height position that becomes a horizontal plane.

  The bathroom floor according to claim 2 is characterized in that the peripheral edge of the upper surface of the convex portion has an R shape.

  The bathroom floor according to claim 3 is characterized in that a hydrophilic treatment is applied to the recess.

  According to the bathroom floor according to claim 1, while the recesses between the convex portions are inclined downward to the drainage side to allow water to pass therethrough, the plurality of convex portions have height positions where the upper surfaces thereof are on the same horizontal plane. Therefore, when sitting on the floor or standing, there is no sense of incongruity, the walking sensation is good, and the elderly can fall over. Moreover, according to this structure, since a walk surface can be made horizontal, the inclination of the recessed part between convex parts can also be made steep, and it can be set as a bathroom floor with good drainage.

  According to the bathroom floor of Claim 2, since the upper surface peripheral part of a convex part is formed in R shape, it is hard to collect water at the upper end of a convex part, and it is easy to flow down, and the standing corner part of a convex part is formed. By making it round, it is possible to make it easy to drain the water that has fallen off without staying in the corner.

  According to the bathroom floor according to claim 3, since the inside of the recess is subjected to hydrophilic treatment, combined with the downward slope structure of the recess, it is possible to effectively drain and reduce residual water on the floor surface, The remaining water can be dried in a short time.

  Hereinafter, a plurality of embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is an explanatory view of a first embodiment of a bathroom floor according to the present invention, in which (a) is a plan view of the bathroom floor and (b) is an enlarged longitudinal sectional view taken along line AA of (a).

  The bathroom includes a bathtub 2, a drainage area 3 adjacent to the bathtub 2, and a washing place 1 adjacent to the drainage area 3. A drainage area 3 is formed along the apron 2a of the bathtub 2 on the end side of the bathtub side of the washing place 1, and a drainage pan 23 is attached to the opening of the drainage groove 20 arranged in the drainage area 3. ing. A drainage port 21 is provided in the approximate center of the drainage groove 20 in the longitudinal direction, and drainage channels 22 having drainage gradients are formed on both sides of the drainage port 21 so that the drainage port 21 is smoothly drained.

  On the other hand, the bathroom floor 10 of the washroom 1 has a downward slope toward the drain groove 20, and the water that has flowed down to the floor surface 11 flows in the direction of arrow F from the upstream side F1 to the downstream side F2, and drains. It is configured to drain into the groove 20.

  In addition, a number of anti-slip convex portions 12 are formed on the inclined floor surface 11. Each of the anti-slip protrusions 12 is formed by a cylindrical isolated protrusion 12A having the same diameter and separated from each other, and a recess 13 for separating the protrusions 12A is formed between the protrusions 12A. They are regularly scattered. The recess 13 forms an inclined flowing water channel 13 that is not interrupted toward the drainage groove 20 and is capable of passing water.

  As shown in FIG. 1 (b), the non-slip convex portion 12A is such that the height from the inclined floor surface 11 of each convex portion 12A increases as it goes downstream F2, and the upper end of these convex portions is increased. The upper end surface (walking surface) 14 formed by connecting 121 is formed to be the same horizontal plane.

  In this way, since the walking surface 14 is substantially horizontal, there is no sense of incongruity when sitting or standing on the bathroom floor 10, and the walking feeling is good, preventing the elderly from falling out of balance and falling down in the washing place 1. be able to. Further, according to this bathroom floor 10, since the walking surface 14 is horizontal, the slope of the floor surface 11 on which the anti-slip convex portion 12A is erected can be made steep, and such steep running water The drainage can be improved by the road. For example, in the case of a bathroom floor having a conventional structure, the water gradient is about 1 degree, but according to the bathroom floor of the present invention, it is possible to make a steep slope of about 2 to 10 degrees, and water adhering to the floor surface Even water droplets with a small surface area relative to the amount can be dropped by gravity.

  Further, in this embodiment, each of the anti-slip convex portions 12A has a cylindrical shape with a rounded upper end 121. For example, as shown in FIG. 1, the hemisphere is placed on the upper end of the cylindrical shape. it can. Further, the corner 15 between the standing base 122 of the anti-slip convex portion 12A and the flowing water channel 13 has a smoothly rounded shape. That is, the convex portion 12A has an R-shaped upper peripheral portion.

  As described above, since the anti-slip convex portion 12A has an R shape, water does not easily collect at the upper end 121 of the convex portion 12A and smoothly flows down, and the water that has flowed down from the convex portion 12A stays in the corner portion 15. It is possible to flow to the flowing water channel 13 without causing it. Also, because of the roundness, it is easy to clean and easily remove dirt.

  The bathroom floor 10 is desirably integrally formed with the anti-slip convex portion 12 and is formed of a material having high hardness so that the high cylindrical convex portion 12A disposed on the downstream side F2 is not deformed. desirable.

  Further, the inclined floor surface 11 including the inside of the recess 13 of the bathroom floor 10 is subjected to a hydrophilic treatment. In addition, not only the inclined floor surface 11 but also the non-slip convex portion 12A may be subjected to hydrophilic treatment, but it is desirable that the inside of the recess 13 is more hydrophilic than the upper surface of the convex portion 12A. Hydrophilic treatment methods include a method of forming the recess 13 with a hydrophilic material, a method of forming a hydrophilic film on the surface, a method of artificially hydrophilizing by providing fine irregularities on the surface, chemical However, any method may be used as long as it is more hydrophilic than the floor material.

  As a method of forming a hydrophilic film, a method of coating a surface with a hydrophilic coating agent such as a hydrophilic paint or a hydrophilic substance is common. In addition, as a method of pseudo-hydrophilization, the surface is mechanically roughened by a known method such as honing, sandblasting, sanding treatment, etc., and the surface tension of water droplets can be destroyed by the unevenness. Alternatively, a hydrophilic method can be used. As a method for chemically hydrophilizing, there can be used a method in which hydrophilic substituents are chemically arranged on the surface using ultraviolet irradiation treatment, ultraviolet laser treatment, plasma treatment, corona discharge treatment, flame treatment or the like.

  Since the inclined floor surface 11 is hydrophilic in this way, the water that has flowed down into the recess (flow channel) 13 does not become water droplets or is immediately broken even if water droplets are formed on the scale. The water gradient of the floor surface 11 can be suitably drained so that water does not remain on the inclined floor surface 11, and even if it remains, the remaining water has wettability by the hydrophilically treated floor and has an air contact area. Since it is large, moisture removal by drying can be performed in a short time.

  2A and 2B are explanatory views of a second embodiment of the bathroom floor of the present invention, in which FIG. 2A is a plan view of the bathroom floor, and FIG. 2B is an enlarged longitudinal sectional view taken along line BB in FIG. In addition, since the positional relationship between the washing place 1 and the bathtub 2 and the structure and arrangement position of the drain groove 20 and the drain port 21 in the drain region 3 are the same as those in the first embodiment, the same configuration is the same. The description thereof will be omitted.

  In this embodiment, each of a large number of anti-slip convex portions 12 formed on the inclined floor surface 11 is formed by a hemispherical isolated protruding portion 12B separated from each other, and the gap between the large number of convex portions 12 is a flow channel. 13 and an upper end surface (walking surface) 14 formed by connecting the upper ends 121 of the convex portions is substantially horizontal. That is, in this embodiment, in order to increase the height from the inclined floor surface 11 of each convex portion 12B as it goes downstream, as shown in FIG. ing.

  As described above, since the walking surface 14 of the bathroom floor 10 of the present embodiment is also horizontal, there is no sense of incongruity when the user sits or stands on the bathroom floor 10 as in the first embodiment, and the walking feeling is also good. In the washing place 1, it is possible to prevent the elderly from falling out of balance and falling.

  Further, in the case of the arrangement as shown in the figure, since the anti-slip convex portion 12B is formed of a hemisphere, the width of the recess (flow channel) 13 is narrowed by gradually increasing the diameter of the hemisphere. Taking such points into consideration, the arrangement shown in the figure cannot make an extremely steep slope, but the anti-slip convex portions 12B are sparsely arranged on the downstream side F2 and densely arranged on the upstream side F1. Thus, the width of the flowing water channel 13 may be secured.

  Further, since the non-slip convex portion 12B is formed in a hemispherical shape and increases in diameter toward the downstream F2, the convex portion 12B has a height from the inclined floor 11 in the downstream F2, Because it is large, it has a sense of stability and is difficult to deform.

  Moreover, as shown in FIG.2 (b), since the standing base 122 of the convex part 12B for slip prevention and the corner part 15 between the flowing water channels 13 become a rounded shape, it is a convex part. The water that has flowed down from 12B can flow into the flowing water channel 13 without staying in the corner 15. Also, because of the roundness, it is easy to clean and easily remove dirt.

  In addition, since the hydrophilic treatment of the inclined floor surface 11 is the same as that of the first embodiment, description of the treatment method and the effect thereof is omitted.

  Further, in the first and second embodiments described above, since the anti-slip convex portion 12 is composed of the isolated protrusions 12A and 12B separated from each other, the contact feeling of the sole is good, and the foot acupuncture massage As an effect can be expected.

  Next, a third embodiment will be described.

  FIG. 3 is an explanatory view of a third embodiment of the bathroom floor according to the present invention, in which (a) is a plan view of the bathroom floor, (b), (c) and (d) are C1-C1 of (a), respectively. , C2-C2, C3-C3 is an enlarged longitudinal sectional view of each line. In addition, since the positional relationship between the washing place 1 and the bathtub 2 of the same embodiment and the structure and arrangement position of the drainage groove 20 and the drainage port 21 of the drainage region 3 are the same as those of the first embodiment, The same reference numerals are given and description thereof is omitted.

  In this embodiment, each of a large number of anti-slip convex portions 12 formed on the inclined floor surface 11 is constituted by a ridge portion 12C in which a ridge line 12Ca is continuous from the upstream side F1 to the downstream side F2 of the bathroom floor 10, The recesses formed in parallel and formed between the convex portions form a straight water channel 13. The recess 13 is subjected to hydrophilic treatment so as to be more hydrophilic than the upper surface of the convex portion.

  As shown in FIG. 3 (b), the ridge 12C is formed so that the ridge line 12Ca is a horizontal straight line, and the upper end surface formed by these many ridge lines 12Ca, that is, the walking surface 14 is a horizontal plane. A feeling is good and can prevent the fall in the washing place 1. Moreover, according to this structure, since the water flow path 13 formed between the convex parts is comprised by the linear concave groove which is not interrupted on the way, water does not remain easily and smooth drainage is realizable. .

  Further, as shown in FIGS. 3 (c) and 3 (d), the protrusion 12 </ b> C has a rounded upper surface peripheral portion, and thus has a synergistic effect with the hydrophilicity in the recess 13. Can further improve drainage. Further, since the ridge portion 12C has a linear shape and the corner portion 15 is rounded, the flowing water channel 13 is easily cleaned, and the corner portion 15 hardly accumulates dirt.

  FIG. 4 is a plan view of a bathroom floor having an inclined floor surface having an inclined shape different from that of FIGS.

  In the bathroom floor 10 shown in this figure, the inclined floor surface 11 is divided into three areas, and the floor surface of each area is inclined downward in the directions of a, b, and c, and the water that has flowed down into the respective areas. However, it flows toward the drainage area 3 composed of the drainage port 21 formed at the approximate center of the apron side end of the bathroom floor 10.

  The walking surface 14 may be horizontal by forming the anti-slip convex portion 12 shown in the first to third embodiments on the inclined floor surface 11 divided into a plurality of areas. In that case, the above-mentioned three types may be combined as the anti-slip convex portion 12, and it is only necessary to form a flow channel 13 through which water flows at least along the directions a, b, and c.

  Note that the three types of anti-slip convex portions 12 may be combined and formed on the inclined floor that is not divided into a plurality of areas, as exemplified in the first to third embodiments.

  Moreover, although the example which provided the drain outlet 21 in the edge of the apron side (longitudinal direction in a figure example) of the washing place 1 was shown above, the edge of the side (short side direction in a figure example) orthogonal to an apron surface was shown. Needless to say, the bathroom floor of the present invention can also be applied to those provided in the above.
