Description

  The present invention relates to a bathroom.

  Conventionally, a waterproof floor pan made of a material such as FRP (fiber reinforced plastic) having a waterproof property has been used as a bathroom floor, and a rock texture pattern or a stone pattern is formed on the surface to improve the design. However, if the drainage is poor, there is a problem that water remains in an island shape on the surface of the waterproof floor pan and does not dry naturally even after a long time. In view of this, a bathroom floor in which a linear hydrophilic portion and a linear water-repellent portion are arranged in parallel with each other and the hydrophilic portion is continuous with a drain port (see, for example, Patent Document 1) has been proposed. This bathroom floor can naturally dry the remaining water on the floor surface in a shorter time by forming a thin water film in the hydrophilic part. There is also known a ventilation / heating type bathroom (for example, see Patent Document 2) that supplies air heated to dryness to a floor member.

By the way, residual water on the floor surface may contain contaminants such as soap stains, sebum, and scales. In this case, even if the residual water on the floor surface is dried as in Patent Document 1 or Patent Document 2, contaminants cannot be removed from the floor surface, and dirt is attached to the floor surface. There are problems such as bad odor. In order to solve this problem, a bathroom floor that is inclined toward a drain outlet and has a water repellent function on the surface is known. This bathroom floor uses the gradient to automatically drain the residual water on the floor surface to the drain, but the small volume of water droplets does not flow only on the floor gradient but stays on the floor surface, resulting in sufficient contamination. It cannot be removed.

  This invention is made | formed in view of the situation as mentioned above, and makes it the subject to provide the bathroom which can remove the residual water of the bathroom floor surface easily and improved antifouling property.

  In order to solve the above problems, the bathroom of the present invention is characterized by the following.

  1stly, the bathroom floor which has a water-repellent function on the surface, The air injection means which injects air toward the drain outlet of a bathroom along the said bathroom floor surface, and pushes out the residual water on the bathroom floor surface toward a drain outlet It is characterized by having.

  Second, in the first invention, the air jetting means is provided in a lower part of a bathroom wall surrounding the bathroom floor.

  Third, in the first or second invention, the bathroom floor has a water-repellent function on the surface having a water contact angle of 70 ° or more and a Φ10 water drop falling angle of 20 ° or less. Features.

  According to the first invention, since the bathroom floor surface has a water repellent function, water droplets are easily formed on the bathroom floor surface, and residual water on the bathroom floor surface easily moves on the bathroom floor surface. Therefore, the remaining water on the bathroom floor surface is easily pushed out and drained toward the drain outlet by injecting air toward the drain outlet of the bathroom along the bathroom floor surface. become. Even water droplets having a small volume are pushed out by air, so that water droplets having a small volume do not stay on the bathroom floor surface as in the prior art. Therefore, contaminants such as soap stains, sebum, and scales contained in the residual water are effectively removed, and the antifouling property is improved.

  According to the second aspect of the invention, the effect of the first aspect of the invention can be substantially improved by specifying the installation location of the air injection means.

  According to the third invention, the bathroom floor has a water repellent function with a water contact angle of 70 ° or more and a Φ10 water drop falling angle of 20 ° or less on the surface. Water droplets are easily formed, and the residual water on the bathroom floor surface further moves on the bathroom floor surface.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a bathroom according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing an installation structure of air injection means in the bathroom.

  As shown in FIGS. 1 and 2, the bathroom according to the present embodiment is composed of a bathroom floor 1, a bathtub 3, side walls 4 a and 4 b, an outer wall 5, an entrance wall 6 having a door 61, a ceiling 7, and the like. Has been. The bathroom floor 1 is provided with a drain port 8 at a substantially central position on the bathtub 3 side, and contaminated water and the like during washing is drained from the drain port 8 to the outside. Further, the bathroom floor 1 has a gradient such that the drainage port 8 is lowest, and the water on the bathroom floor 1 flows along this gradient and is easily collected toward the drainage port 8.

  The bathroom floor 1 is formed from a resin material such as FRP, and has a water repellent function on the surface. The water repellent function is desired to have, for example, the characteristics that the water contact angle is 70 ° or more and the Φ10 water droplet falling angle is 20 ° or less. More preferably, the water contact angle is 80 ° or more, and the Φ10 water droplet falling angle is 20 ° or less. As a result, water droplets are easily formed on the surface of the bathroom floor 1, and residual water on the surface of the bathroom floor 1 easily moves on the surface of the bathroom floor 1. Such a water-repellent function is realized by applying a water-repellent paint such as a fluorine-based paint or a silicon-based paint to the surface of the bathroom floor 1 by various methods such as spray coating, lip coating, and brush coating.

  Furthermore, the bathroom of the present invention has air injection means. The air injection means is not particularly limited as long as it can inject air in the direction of the bathroom outlet along the bathroom floor surface and push out the remaining water on the bathroom floor surface in the direction of the outlet. The air injection means 2 according to the present embodiment is provided with pipes 22 made of hard vinyl chloride resin for supplying air into the side walls 4a and 4b surrounding the bathroom floor 1 and the lower wall of the entrance / exit wall 6, and the pipes. A plurality of air nozzles 21 are attached obliquely downward with a predetermined interval, that is, toward the bathroom floor 1, and air is ejected from the front end portion 211 of the air nozzle 21 to a wide angle. The tip 211 of each air nozzle 21 is directed in the direction of the drain 8, and the air jetted from the tip 211 of the air nozzle 21 flows in the direction of the drain 8 along the surface of the bathroom floor 1. The height of the pipe 22, the number of air nozzles 21 attached to the pipe 22, the spacing between the air nozzles 21, the angle of attachment of the air nozzle 21 to the pipe 22, etc. 1 is adjusted and set appropriately so as to spread throughout.

  Further, an air supply unit 23 such as a compressor or an air tank is connected to the pipe 22, and the compressed air generated by the air supply unit 23 is supplied to the pipe 22 through the on-off valve 24 and is injected from the tip end portion 211 of the air nozzle 21. The The control unit 25 controls the opening / closing of the opening / closing valve 24 and the air pressure of the injected air. Therefore, when the residual water on the surface of the bathroom floor 1 is drained, the controller 25 sets the air pressure to a predetermined value, opens the on-off valve 24, and injects air from the tip 211 of the air nozzle 21.

  In the bathroom of the present invention, the surface of the bathroom floor has a water-repellent function. As described above, the residual water on the surface of the bathroom floor has a predetermined water contact angle and is easy to move on the surface of the bathroom floor. . In addition, water droplets are easily formed on the bathroom floor surface. Therefore, for example, as shown in FIG. 2, when air is ejected from the tip 211 of the air nozzle 21 along the surface of the bathroom floor 1 in the direction of the drainage port 8, the drainage port 8 is caused by the air sprayed with the water droplets A on the bathroom floor 1. It is easily pushed out and drained. Therefore, contaminants such as soap stains, sebum, and scales contained in the water droplet A are effectively removed, and the antifouling property is improved.

  In the said embodiment, although the air nozzle is installed in the lower part of the both-sides wall and the entrance-and-exit wall which enclose a bathroom floor, air is injected from three directions, It is not limited to this in particular. For example, when the drain outlet is disposed on one side wall side, an air nozzle is installed at the lower part of the other side wall facing the side wall and the lower part of the entrance / exit wall so as to inject air from two directions. Alternatively, it may be installed only at the lower part of the opposite side wall so as to inject air from one direction. As for the shape of the tip of the air nozzle, various shapes such as a circular shape and a wide shape can be used. Moreover, in the said embodiment, although air is injected at a wide angle from the front-end | tip part of an air nozzle, it is made to inject a strip | belt-shaped air film along a bathroom floor surface using the slit nozzle which produces | generates a strip | belt-shaped air film | membrane. There is no particular limitation.

<Examples 1-3, comparative example>
A coating (thickness 3 μm) was applied with a water repellent paint on the surface of “Floor White Gray” (specific gravity 1.8, thickness 3 mm) manufactured by Matsushita Electric Works, Ltd. (Examples 1 to 3). As a result, a bathroom floor having the water-repellent function on the surface having the water-repellent characteristics (Φ10 water drop falling angle, water contact angle) shown in Table 1 was obtained. Also, a bathroom floor not subjected to water repellent treatment was prepared, and this was used as a comparative example.

Water drops having a predetermined water droplet diameter (Φ5, Φ10, Φ20) shown in Table 1 are prepared on each bathroom floor, and both side walls and entrance walls surrounding the bathroom floor as shown in FIGS. 1 and 2 Air was jetted along the bathroom floor surface in the direction of the drain outlet at the air pressure (0.25, 0.5, 1, ² [kgf / m ² ]) shown in Table 1 from the air nozzle disposed in the lower part of the wall. The state of each water droplet on the bathroom floor was observed, and in the case of a water droplet diameter of Φ5, the evaluation was also made when the water droplet was supplied to the groove portion of the bathroom floor.

  `` ◎ '' when water drops are pushed out by air and moved well, `` ○ '' when pushed by air and moved slowly, moved slowly by being pushed out by air, but stopped at the side joint on the bathroom floor Was evaluated as “△”, when it was pushed out by air and slowly moved, but stopped at the flat part, “×”, and when the water droplet did not move by air, “XX”. Note that “*” indicates that the water droplets were not drained from the drain port because the shape of the water droplets collapsed or was blown away by air.

  Table 1 shows the results.

表１の結果より、表面に撥水機能を有する浴室床（実施例１〜３）に対してエアを噴射することで、その浴室床上の水滴をエアで押し出すことができることを確認した。これにより、浴室床上の水滴を排水できることがわかった。一方で、表面に撥水機能を有していない浴室床（比較例）に対してエアを噴射しても、その浴室床上の水滴を押し出すことができないか、あるいは水滴が吹き飛ばされて排水口より排水されずに残ってしまうことが確認できた。

From the results in Table 1, it was confirmed that water droplets on the bathroom floor can be pushed out by air by spraying air onto the bathroom floor (Examples 1 to 3) having a water repellent function on the surface. Thereby, it turned out that the water droplet on a bathroom floor can be drained. On the other hand, even if air is sprayed onto a bathroom floor (comparative example) that does not have a water-repellent function on the surface, water droplets on the bathroom floor cannot be pushed out, or water droplets are blown off and discharged from the drain outlet It was confirmed that it remained without draining.

It is a schematic block diagram of the bathroom which concerns on one Embodiment of this invention. It is sectional drawing which shows the installation structure of the air injection means of the bathroom of FIG.
