Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bathroom with a floor panel in which drying of water is hastened.
[0002]
[Prior art]
Since the bathroom is used by infants and the elderly, it is required to have a safe structure in which the floor does not slip. Also, in order to keep the bathroom clean, it is desirable to dry the interior surface of the bathroom as soon as possible. Regarding the floor panel surface of a bathroom, Patent Literature 1 discloses that a large number of protrusions having irregularities for preventing slippage at the tip end surface project close to each other, and the upper surface of the floor panel body between the protrusions is a smooth surface. A water flow section is formed between the adjacent protrusions, and the front end face of the protrusion has a shape that is longer in the gradient direction of the upper surface of the floor panel main body and both ends in the longitudinal direction are narrower than the middle part. A bathroom floor pan is disclosed, wherein both side edges of the protrusion are curved and side edges of adjacent protrusions are curves of different shapes from each other. It is described that an effect of not slipping even when stepping on is exerted.
[0003]
On the other hand, in Patent Literature 2, convexities for preventing slippage are formed on the surface, and a flow path that is continuous with the drain port or the sink groove is formed between the convexities, and at least the surface tension of the polka dots is broken on the flow path. There is disclosed a bathroom floor panel in which uneven portions are formed so as to overlap with each other. According to the bathroom floor panel disclosed in Patent Literature 2, even if water remains on the surface due to use the previous night, the effect of being surely dried on the next day is obtained.

JP-A-2002-54295
[Problems to be solved by the invention]
However, according to the structure of the bathroom floor panel disclosed in Patent Literature 1, although the effect of not sliding in any direction can be obtained, it is not so great in removing moisture remaining on the floor panel surface. No effect has been observed. Further, according to the structure of the bathroom floor panel disclosed in Patent Document 2, by destroying the polka dots formed on the floor panel surface, the moisture is surely dried the next day, but the floor panel surface has It has a structure in which a certain amount of water remains, and since this remaining water is removed from the floor surface only by evaporation, there is a problem that it is necessary to wait a predetermined time to evaporate all the remaining water. .
[0005]
Therefore, an object of the present invention is to provide a bathroom provided with a floor panel that can easily remove moisture remaining on the surface while maintaining an anti-slip effect.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the inventors of the present application note that in the above-described conventional technology, it takes a long time to evaporate moisture on the floor panel, and the amount of residual water on the floor panel upper surface to be evaporated is determined. The idea was obtained that the drying time as a whole can be greatly reduced by minimizing the amount of drying. For this reason, the structure of the flow path is devised so that the water on the upper surface of the floor panel can be guided to the drain as much as possible, and the structure of this flow path can be produced by an easy process during press molding. And
[0007]
Hereinafter, the present invention will be described specifically. In addition, in order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are added in parentheses, but the present invention is not limited to the illustrated embodiment.
[0008]
The bathroom (1) of the present invention has a panel connected to the floor panel (5) of the washing room (2) at least on the side of the bathtub washing room side elevation (23) or the lower part of the front side elevation of the counter (6). And a concave portion corresponding to the convex portion by providing a large number of planar convex portions (40, 40a, 40b, 40c) close to the upper surface of the floor panel of the washing room. Are formed as upper surface channels (41, 42, 43, 44), and one end of the drainage channel on the washing side elevation (24) communicates with the upper surface channel, and the other end of the drainage channel on the washing channel side elevation. An upright channel (50) reaching the lower half (24L) is provided, and the shape of the upright channel is formed so that an undercut portion does not occur during panel molding. It is. Here, "undercut" refers to a concave / convex portion of a mold or a molded article that hinders removal of the molded article from the mold.
[0009]
ADVANTAGE OF THE INVENTION According to the bathroom which concerns on this invention, since many planar convex parts are provided closely on the floor panel upper surface of a washroom, it is difficult for a bathroom user to slip in any way, and it is a safe bathroom. Can be configured.
[0010]
In addition, since the upper channel and the vertical channel communicate with each other, and the vertical channel is provided so as to reach the lower half of the drainage groove, water remaining on the upper surface of the floor panel is removed by the upper channel. From the drain through the vertical channel. Therefore, no water remains near the boundary between the upper surface of the floor panel and the drain, and most of the water on the upper surface of the floor panel is quickly removed, and the amount of water remaining on the floor panel is small. It becomes possible to dry the entire upper surface of the floor panel inside.
[0011]
Also, there is no undercut portion in the shape of the upper channel. The shape without the undercut portion can be achieved, for example, by forming the vertical flow path in a direction substantially perpendicular to the length direction of the drain groove. As described above, since the shape of the upper surface flow path of the bathroom according to the present invention does not have an undercut portion, the same mold can be made at the same cost as a conventional floor panel in which a groove is formed only in a flat portion. The floor panel is press-molded by a method such as SMC or BMC molding. “SMC molding” refers to a method of molding a sheet-like molding material using a compression molding machine and a mold. It is mainly used to produce large molded products by reinforced fiber plastic (FRP). In addition, “BMC molding (bulk molding compound molding)” means using a reinforcing fiber base material mainly composed of chopped strands and a bulk molding material BMC in which a matrix is previously kneaded, charging a heated mold and closing the mold. It refers to the method of molding.
[0012]
As described above, by adopting a configuration that does not generate an undercut portion as the shape of the vertical flow path, it is possible to use an inexpensive mold having a simple shape, thereby improving productivity and contributing to cost reduction. It becomes easier. In addition, there is an advantage that the use of such a mold reduces the occurrence of failure during molding.
[0013]
Such actions and advantages of the present invention will be apparent from embodiments described below.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the drawings.
[0015]
FIG. 1 is a plan view showing the entire bathroom. FIG. 2 is a diagram schematically showing a cross section taken along line II-II in FIG. Hereinafter, a bathroom 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Bathroom 1 is formed as a so-called unit bath. FIG. 2 shows the lower part of two cross sections 21 and 22 of the four walls standing upright among the six surfaces constituting the substantially rectangular parallelepiped unit bath. On the other hand, the upper portions of the cross sections 21 and 22 and the ceiling are not shown. According to the plan view shown in FIG. 1, the bathroom 1 is divided into a washing place 2 and a bathtub area 3. The washing place 2 is partially open at the side surface 21 and is provided with a bathroom doorway 4.
[0016]
A person using the bathroom 1 can push the door 4a provided at the bathroom entrance 4 toward the inside of the bathroom to open the washing room 2 inside the bathroom. The washing room 2 has a bottom surface configured as a floor panel 5. A counter 6 is provided on one end side in the longitudinal direction of the washing place 2, and the counter 6 is provided with a mirror, a soap storage place, and the like as necessary, for the convenience of the user.
[0017]
Bathtub 11 is provided in bathtub area 3. A drain port 12 is provided at the bottom of the bathtub 11, and when used, a bath plug 12 a is fitted therein, and hot water is stored in the bathtub 11. A faucet 14 a and a faucet 14 b are provided on the side of the bathtub 11 in the bathtub area 3, and by operating them, hot water at a desired temperature can be poured into the bathtub 11 from the faucet 13. Although the hot water is supplied by a hot water heater (not shown), its description is omitted because it has no direct relation to the present invention.
[0018]
A drain 7 is provided between the bathtub area 3 and the washing place 2. In addition, a drain groove 7a is also provided at an end of the side of the washing place 2 where the counter 6 is provided (in a plan view of FIG. 1, the drain groove 7a is located at a hidden position below the counter 6). Therefore, it is indicated by a two-dot chain line.) Further, a drain trap 8 is provided at one end of the drain grooves 7 and 7a, and the upper part thereof is covered with a trap cover.
[0019]
The hot water overflowed from the bathtub 11 is discharged from a drain trap 8 to a drain system (not shown) through a drain groove 7. On the other hand, the floor panel 5 of the washing room 2 is slightly inclined from the bathroom entrance 4 to the drain trap 8. That is, in the vertical direction in FIG. 1, the slope is provided from the side opposite to the side where the counter 6 is provided of the washing place 2 toward the side where the counter 6 is provided so that the upper side is higher and the lower side is lower. I have. In the left-right direction, an inclination is provided from the side opposite to the side adjacent to the bathtub area 3 of the washing room 2 to the side adjacent to the bathtub area 3 so that the left side is higher and the right side is lower. (In the left-right direction, the slope gradually becomes lower from A to B between AB in FIG. 2). Therefore, in the washing place 2, the hot water washed by the user is inclined to the floor panel 5. The water flows along the drains 7 and 7a along the drain, and is discharged from the drain trap 8 to the drain system.
[0020]
In the present embodiment, the preferred gradient is 1/30 to 1/60, more preferably 1/40 to 1/50. If the slope is steeper, the comfort of the bathroom is lost. If the gradient is gentler, the drainage performance will be insufficient.
[0021]
The drain grooves 7, 7a are formed in a substantially "U" -shaped cross section. Since the bathroom 1 is formed as a unit bath, the floor panel 5, the drains 7, 7a, and the bathtub 11 are integrally formed continuously. Therefore, the upper end of the washroom-side standing surface 24 of the drainage groove 7 is provided continuously to the end of the floor panel 5. On the other hand, the lower part of the bathtub-washing-stand-side standing surface 23 is a bathtub-side standing surface of the drainage groove 7.
[0022]
FIG. 3 is an enlarged view of an upper surface portion of the floor panel 5 indicated by III surrounded by a broken line in FIG. 1, and FIG. 4 is an enlarged view of the upper surface of the floor panel 5 indicated by IV surrounded by a broken line in FIG. It is a figure which expands and shows a part further. FIG. 5 is a perspective view of the panel of the bathroom 1 in which a portion from the washing place 2 to the lower part of the washing-stand-side standing surface 23 of the bathtub 11 via the drainage groove 7 is cut out. (A) is a perspective view from a viewpoint at a diagonal upper left vicinity of 45 °, and (b) is a perspective view from the front slightly above. FIG. 6 is a diagram schematically showing a cross section taken along line VI-VI in FIG. Hereinafter, the drainage structure of the floor panel 5 and the drainage groove 7 will be described with reference to FIGS.
[0023]
On the upper surface of the floor panel 5, a large number of vertical upper channels 41, 41, 41,... And horizontal upper channels 42, 42, 42,. A large number of rectangular projections 40, 40, 40,... Are formed so as to be surrounded by the upper and lower flow paths formed in the vertical and horizontal directions. Further, in each of the planar convex portions 40, oblique flow channels 43 and 44 are provided so as to divide the convex portions 40 in an oblique direction in plan view. The planar convex portion 40 is divided into three areas 40a, 40b, and 40c by the oblique flow channels 43 and 44. Both ends of the oblique flow paths 43 and 44 communicate with any of the vertical upper flow paths 41, 41, 41,..., The horizontal upper flow paths 42, 42, 42,. I have. The direction in which the planar convex portions 40 are divided by the oblique flow channels 43 and 44 is not fixed but is randomly arranged.
[0024]
With reference to FIG. 5A, the vertical upper surface flow paths 41, 41, 41,... Are formed only on a plane portion formed by the floor panel 5 among the surfaces from the floor panel 5 to the drainage grooves 7. I have.
[0025]
On the other hand, the horizontal upper surface flow paths 42, 42, 42, ... are continuously formed from the floor panel 5 to the curved surface from the drain groove 7, and constitute the vertical flow paths 50, 50, 50, ... in the drain groove 7. ing. , Which are provided continuously from the lateral upper surface channels 42, 42, 42,... Up to the lower half 24L. Here, the lower half portion of the washing side standing surface 24 of the drainage groove 7 is defined as the height H of the upper surface (flat portion) of the floor panel 5 and the height of the bottom surface of the drainage groove 7 (the height of the lowest portion when there is no flat surface). S) It means the washing-ground-side elevation of the drain gutter 7 located below the average height M with L (see FIG. 6).
[0026]
In the present embodiment, the shape of the planar convex portion 40 including the three areas 40a, 40b, and 40c partitioned by the oblique flow channels 43 and 44 does not necessarily need to be a square, and may be a rhombus or a rectangular square. For example, it may be a triangle, a pentagon or more polygon.
[0027]
From the viewpoint of quickly leading residual water to the drainage ditch without generating polka dots on the floor panel 5, and when the length of one side of the planar convex portion 40 is 5 mm to 15 mm, more preferably, 8 mm to 12 mm Good. In addition, from a similar viewpoint, the shape of the three areas 40a, 40b, and 40c is a polygon such as a triangle, a quadrangle, and a pentagon, and the length of one side is preferably 3 mm to 10 mm.
[0028]
Also, with respect to the flow paths 41, 42, 43, and 44, the width is 0.6 mm to 2.0 mm at the bottom from the viewpoint that the polka dots are not generated on the floor panel 5 and the residual water is quickly guided to the drainage ditch. And more preferably 0.8 mm to 1.0 mm. Similarly, the depth of the flow path is desirably 0.6 mm to 1.2 mm, more preferably 0.7 mm to 0.9 mm. Further, it is preferable that the depth and the width of the flow path are formed substantially constant in order to quickly guide the residual water to the drain groove 7.
[0029]
The bathroom 1 in which the flow channels 41, 42, 43, 44 and 50 of the floor panel 5 and the drainage groove 7 are formed as described above has the following features. That is, a large number of planar convex portions 40 are formed on the upper surface of the floor panel 5, and each of the planar convex portions is divided by a flow path in a direction different from the four sides of the planar convex portion 40, and Since the direction of the division is randomly arranged in each planar convex portion, the floor surface has a structure in which it is hard to slide in any direction and a polka dot is hardly formed. In addition, the channels 41, 42, 43, and 44 formed in the vertical and horizontal directions and the oblique directions on the upper surface of the floor panel 5 correspond to the rising flow extending to the lower half 24 </ b> L of the washing-side standing surface 24 of the drainage groove 7. Because of the passage 50, the water on the floor panel 5 is quickly drained by these channels 41, 42, 43, 44, 50, in combination with the moderate inclination of the floor panel 5. And the residual water on the floor panel 5 is extremely small. Therefore, it is easy to shorten the time required for residual water to evaporate, and quick drying of the floor panel 5 can be realized.
[0030]
FIG. 7 is a schematic cross-sectional view showing a die-cutting step when press-molding a section of the cross section shown in FIG. 6 (hereinafter referred to as “panel 80”). In the press molding of the panel 80, a predetermined material such as FRP is filled between the upper mold 60 and the lower mold 70, and after compression, the upper mold 60 and the lower mold 70 are separated vertically to form a product. The panel 80 can be obtained. When the upper die 60 and the lower die 70 are pulled apart in the vertical direction, if the shape of the panel 80 has a so-called undercut portion, the product and the mold cannot be separated properly. In this method, it is necessary to form the mold of this part as a separate body (slide core) and move the slide core each time the mold is opened and closed before taking out the product. Therefore, if there is an undercut portion, a complicated and expensive mold and a complicated process are required, and failures often occur during molding.
[0031]
However, in the bathroom 1 according to the present embodiment, the vertical flow paths 50, 50, 50,... Since no flow path was provided in the lower part, it was possible to form a flow path to the lower half 24L of the upright surface on the drainage ditch washing side without producing an undercut. Therefore, when a panel is press-molded with a material such as SMC or MBC, an inexpensive mold having a simple shape can be used, which facilitates improvement in productivity and cost reduction. In addition, there is an advantage that the use of such a mold reduces the occurrence of failure during molding.
[0032]
When manufacturing the bathroom 1 of the present embodiment, it is desirable that the draft angle (the angle of the product upright portion with respect to the die-cutting direction) be 3 ° or more. If the draft angle is less than this, a large friction occurs between the mold and the product at the time of removing the mold, which may undesirably damage the product surface.
[0033]
【Example】
<1> Test method A panel was fixed to a device capable of changing the gradient, and a predetermined amount of water was poured slightly above the center of the panel (on the side opposite to the drain). The flow of water at this time was visually observed. The time until the panel surface was completely dried was measured.
[0034]
<2> The test condition gradient was set to 1/60. The amount of water poured was 100 cc. The ambient temperature during drying was 30 ° C. and the humidity was 60%.
[0035]
<3> Panel A to be evaluated Panel A: according to the embodiment of the present invention.
Panel B: Panel A in which an upright channel is not formed.
[0036]
<4> In the evaluation result panel A, polka dots were not formed due to the planar projections, and water flowed into the vertical and horizontal flow paths and the skewed flow path, and all water was discharged in a state where no water remained in the planar projections. Was drained without interruption into the drain. In addition, a small amount of water remaining in a wet state on the panel was completely evaporated in one hour, and the upper surface of the panel was in a dry state.
[0037]
On the other hand, in the panel B, although no polka dots were formed on the upper surface, clear water residue was recognized at the drainage ditch of the panel. All of this water residue did not evaporate even after 1 hour, and a part remained. In panel B, since no vertical channel is formed, the water on the floor panel is guided to the end of the curved floor panel where the floor panel and the drain channel vertical surface are continuous due to the inclination and the flat channel of the floor panel. Where water droplets of a certain size are formed due to the surface tension of the water. If the water droplet exceeds a predetermined size, the surface tension cannot withstand the inclination of the curved surface, and the water droplet falls into the drain. Therefore, when the water content on the floor panel decreases, the water droplets formed at the edge of the floor panel can no longer be large enough to fall along the slope of the curved surface toward the drainage ditch, and the water droplets are not half-sized. Water drops remain at the end of the floor panel as they are. It is recognized that the water residue after 1 hour was observed because the remaining water remained without evaporating.
[0038]
Although the present invention has been described in connection with the most practical and preferred embodiments at this time, the present invention is not limited to the embodiments disclosed herein. Rather, it can be modified as appropriate without departing from the spirit or spirit of the invention which can be read from the claims and the entire specification, and a bathroom with such a change is also understood as being included in the technical scope of the present invention. It must be.
[0039]
For example, the following modifications should be interpreted as belonging to the technical scope of the present invention.
[0040]
<Modification> In the above embodiment, the example in which the bathroom is configured as a unit bath has been described. However, in the present invention, it is sufficient that the floor panel and the drainage groove are integrally formed, and the bathtub, side wall, doorway, The ceiling and the like may be formed separately.
[0041]
In addition, as the material for forming the floor panel and the drainage channel, SMC and BMC have been described as examples, but the present invention is not limited to this. For example, the material can be made of a metal material such as stainless steel. .
[0042]
Furthermore, although the example in which the drainage grooves are provided on both the bathtub side and the counter side is shown, the drainage grooves may be provided on only one of them.
[0043]
【The invention's effect】
As described above, according to the bathroom of the present invention, since a large number of planar protrusions are provided close to the upper surface of the floor panel of the washing room, the bathroom user slides in any direction. It is possible to compose a safe bathroom in which it is difficult to occur.
[0044]
In addition, since the upper channel and the vertical channel communicate with each other, and the vertical channel is provided so as to reach the lower half of the drainage groove, water remaining on the upper surface of the floor panel is removed by the upper channel. From the drain through the vertical channel. Therefore, no water remains near the boundary between the upper surface of the floor panel and the drain, and most of the water on the upper surface of the floor panel is quickly removed, and the amount of water remaining on the floor panel is small. The inside of the floor panel can be dried.
[0045]
In addition, since there is no undercut in the shape of the upper channel, it is possible to use an inexpensive mold having a simple shape when press-molding the floor panel with a material such as SMC and BMC, thereby improving productivity. Also, it is easy to contribute to cost reduction. Further, by using such a mold, the same mold can be produced at the same cost as the conventional mold in which the groove is formed only in the flat portion, and there is an advantage that occurrence of failure during molding is small.
