A concave drainage basin 106 is formed in the vicinity of the boundary between the bathtub 104 and the washing place 102 on the floor 102A.

  A drainage port 108 is formed at the center of the bottom of the drainage basin 106, and the drainage that has flowed into the drainage basin 106 from the floor 102A flows into the sewage through a drainage pipe (not shown). In addition, a hair catcher 110 that collects hair and the like is supported on the step portion 108A formed in the drain port 108 (see FIG. 2).

  A drainage lid 10 is installed at the bottom of the drainage basin 106 so as to cover the opening surface of the drainage basin 106. At this time, the plurality of leg portions 12 and auxiliary leg portions 22 formed on the back surface of the lid body 14 of the drainage lid 10 are placed on the bottom of the drainage trough 106.

  Further, a finger hook portion 112 that is recessed in a substantially semi-cylindrical shape from the upper surface of the floor 102A is formed on the upper portion of the side wall of the drain rod 106 on the bathtub 104 side. The drainage lid 10 installed in is removed.

  As shown in FIG. 2, the bottom of the drainage basin 106 is gently inclined downward toward the drainage port 108. A step 108 </ b> A is formed around the drain port 108. A flange portion 110A formed on the outer peripheral portion of the hair catcher 110 is placed on the step portion 108A, and the upper surface of the hair catcher 110 and the opening edge portion of the drain port 108 are at the same height. The hair catcher 110 is formed with a number of water holes 116 through which drainage flows.

  Further, the outer peripheral portion of the upper surface of the lid body 14 and the floor 102A have the same height, and the central portion of the upper surface of the lid body 14 is formed higher than the floor 102A, and the direction of the arrow from the central portion toward the outer peripheral portion. A downward inclined surface is formed on the surface. In addition, the outer shape of the lid body 14 is set to a size that creates a gap between the lid body 14 and the opening edge portion 106 </ b> A of the drainage basin 106.

  Further, the lid body 14 will be described in more detail. As shown in FIG. 3, the lid body 14 is a rectangular flat plate member and is made of a synthetic resin such as an ABS resin. A rhombus region 14A is formed at the center of the upper surface of the lid 14 by four grooves 18A from the four corners toward the center, and the center line CL on the short side of the lid 14 of the region 14A The ridgeline 15 is formed in the. The region 14A is a downwardly inclined surface with the ridge line 15 as the top. Here, the center line CL refers to a straight line that connects points that bisect the short side of the lid 14 and a straight line that connects points that bisect the long side. The same applies to the following description.

  On the short side of the upper surface of the lid body 14, a triangular region 14 </ b> B is formed by the above-described groove 18 </ b> A and the short side of the lid body 14. Further, on the long side of the upper surface of the lid body 14, the trapezoidal region 14 </ b> C is formed on each long side by the groove 18 </ b> A and the groove 18 </ b> B formed from the center of the long side toward the region 14 </ b> A. Two are formed. The regions 14 </ b> B and 14 </ b> C are inclined downward toward the outer periphery of the lid body 14.

  As shown in FIG. 4, the back surface 14 </ b> D of the lid body 14 is inclined downward from the outer peripheral portion of the lid body 14 toward the center portion (see FIG. 2). A ridge line 26 is formed on the diagonal line of the back surface 14D. The respective inclined surfaces are inclined downward toward the outer peripheral portion of the lid body 14 with the ridge line 26 as a boundary.

  At the corner of the back surface 14D of the lid body 14, columnar leg portions 12 are formed protruding downward. Further, leg reinforcing ribs 12 </ b> A connected to the lid body 14 are formed on the outer peripheral portions of the respective leg portions 12.

  Further, a cross-shaped lid reinforcing rib 24 extending from the center of the lid 14 to the center of each side of the lid 14 is formed on the back surface 14D of the lid 14. The lid reinforcing rib 24 is inclined downward from the center of the lid 14 toward the center of each side, and the cross-sectional shape of the lid reinforcing rib 24 is substantially semicircular, which makes it easy to clean. Yes.

  A cylindrical auxiliary leg portion 22 is formed at the end of the lid reinforcing rib 24. The auxiliary leg portion 22 has the same height as the leg portion 12, and an auxiliary leg portion reinforcing rib 22 </ b> A connected to the lid body 14 is formed on the outer peripheral portion of the auxiliary leg portion 22.

  As shown in FIGS. 3 and 4, the outer periphery of the lid body 14 is rounded and rounded, and a recess 20 as a water inlet is formed on the four sides by recessing the outer periphery of the lid body 14 inward. Is formed.

  The recess 20 is formed only on the right side of the center line CL of the lid body 14 and has a length slightly shorter than half of each side. Further, as shown in FIG. 5, when the drain lid 10 is placed on the drainage basin 106, the amount of dent of the recess 20 does not allow a finger to enter between the lid 14 and the opening edge 106 </ b> A of the drainage basin 106. Is set to about.

  In addition, as long as the recessed part 20 is formed in the right side from the center line CL of the cover body 14, it does not need to be continuously recessed from the center line CL to the edge part of a side, and the some recessed part 20 is intermittently formed. It may be formed. Further, even if the recess 20 is formed beyond the center line CL, a swirling flow is generated if the center of the main flow of drainage flowing into the recess 20 flows to the right of the center of the drainage basin 106.

  In the present embodiment, the lid body 14 has a rectangular shape, but may have other shapes. For example, when the lid body 14 is a triangle, the concave portion 20 is formed by indenting the right side from the central portion of each side of the lid body 14, and the center of the main flow of drainage flowing into the concave portion 20 is the central portion of the drainage tub 106. A swirling flow is generated by making it flow on the right side.

  Next, the operation of the drain lid 10 according to the present embodiment will be described.

  As shown in FIG. 5, a gap 28 is formed between the recess 20 formed by recessing the four sides of the lid body 14 and the opening edge 106 </ b> A of the drainage basin 106. Further, the outer shape of the lid body 14 excluding the concave portion 20 is formed in such a size that a gap 30 as an auxiliary water inlet is formed between the outer peripheral portion of the lid body 14 and the opening edge portion 106 </ b> A of the drainage basin 106. In addition, the amount of recesses 20 is set so that the inflow area where the drainage flows from the gap 28 is larger than the inflow area where the drainage flows from the gap 30.

  Here, when drainage flows from the bathtub 104 (see FIG. 1) or a shower (not shown) to the washing place 102, the drainage flows through the floor 102A and reaches the opening edge 106A of the drainage basin 106, and from the gap 28 and the gap 30. It flows into the drain 106.

  At this time, the center of the main flow of the drainage flowing into the drainage basin 106 from the gap 28 is guided to the right side with respect to the center line of the lid body 14 and flows in the direction of arrow A. Turn left around.

  Similarly, when the center of the main flow of the drainage flowing into the drainage basin 106 from the gap 28 on the four sides flows in the direction of arrow A, a swirl flow C that turns left around the central portion of the drainage basin 106 is generated. The swirl flow C is drained to the drain outlet 108 through the water passage hole 116 while swiveling left on the hair catcher 110.

  In addition, the wastewater introduced from the gap 30 into the drainage basin 106 flows in the direction of arrow B, but since the amount of drainage is less than the wastewater that flows in from the gap 28, it merges with the main stream flowing in the direction of arrow A and swirls C It becomes. Here, the hair or the like mixed in the drainage is not entangled in the water passage hole 116 but is collected on the hair catcher 110 while turning left around the central portion of the drainage basin 106 by the swirling flow C.

  In this embodiment, the recesses 20 are formed on the four sides of the lid body 14. However, for example, the recesses 20 may be formed only on two opposing sides, or the recesses 20 may be formed only on one side. Good. In this case, the swirling flow can be generated by denting the recess 20 so that the inflow area of the wastewater flowing from the gap 28 is larger than the inflow area of the wastewater flowing from the gap 30.

  In order to further increase the amount of drainage, the gap 30 may be widened by denting the left side of the center line CL on the four sides of the lid body 14. In this case, as described above, the inflow area of the waste water flowing from the gap 28 is made larger so that the swirling flow C is not affected.

  Further, in the present embodiment, the recess 20 is formed on the right side of the center line CL of the side of the lid body 14. However, the recess 20 may be formed on the left side of the center line CL by reversing the direction in which the recess 20 is formed. . In this case, the main flow of the drainage flowing into the drainage basin 106 from the gap 28 is led to the left side from the central portion of the drainage basin 106, and a swirling flow that turns right around the central portion of the drainage basin 106 is generated. Here, in the northern hemisphere, it is easy to turn left by the Coriolis force, but since the Coriolis force acting on the drainage is small, it does not affect the turning flow turning right. Moreover, the corner | angular part of the cover body 14 is not recessed, and it is trying for the intensity | strength of the cover body 14 not to fall more than necessary.

  Next, a drain lid 50 according to a second embodiment of the present invention will be described. In addition, the thing of the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits suitably and demonstrates.

  As shown in FIG. 6, the drainage lid 50 according to the present embodiment is a rectangular resin member, and the side wall 54 extending downward from the outer peripheral portion of the lid body 52 is positioned on the right side of the center line CL of the side wall 54. A first opening 56 having a height of about two-thirds of the side wall 54 and a length of about half of the side wall 54 is formed.

  Further, on the left side of the center line CL of the side wall 54, a second opening 58 is formed by cutting out the side wall 54 continuously with the first opening 56. The length of the second opening is the same as that of the first opening 56, and the height is about one third of the side wall 54.

  The first opening 56 and the second opening 58 are formed on the four side surfaces of the drain lid 50. Note that the configuration of the upper surface 52 is the same as that of the first embodiment, and a description thereof will be omitted.

  When the drainage lid 50 is placed on the drainage basin 106 of FIG. 5 and drainage flows, the drainage lid 50 flows into the drainage basin 106 from the first opening 56 and the second opening 58.

  Since the opening area of the first opening portion 56 is larger than that of the second opening portion 58, the wastewater introduced from the first opening portion 56 to the right side of the center line CL of the drainage lid 50 becomes the mainstream of the drainage trough 106. A counterclockwise swirling flow is generated by turning counterclockwise around the center.

  Further, since the amount of drainage flowing into the drainage basin 106 from the second opening 58 is smaller than the amount of drainage flowing from the first opening 56, the drainage merges into the counterclockwise swirling flow. Therefore, hair or the like mixed in the drainage is collected to the center of the bottom of the drainage basin 106 while turning counterclockwise by the swirling flow and collected together on the hair catcher 110 (see FIG. 5).

  In the present embodiment, the first opening 56 and the second opening 58 are continuously formed. However, the first opening 56 and the second opening 58 may be separated by the side wall 54 or only the first opening 56 may be formed. good. Alternatively, the side wall 54 may be cut out to form a slit-like through-hole to form the first opening 56 and the second opening 58.

  Next, a drain lid 70 according to a third embodiment of the present invention will be described. In addition, the thing of the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits suitably and demonstrates.

  As shown in FIG. 7, the drain lid 70 according to this embodiment includes a flat lid 72, and columnar legs 74 are formed on the back surface of the drain lid 70 from the corners of the lid 72. It is formed to protrude downward.

  A slit hole 76 that penetrates the lid 72 is formed in the outer periphery of the lid 72. The slit hole 76 includes a first slit 76 </ b> A formed on the right side of the center line CL of the lid body 72 and a second slit 76 </ b> B formed on the left side of the center line CL of the lid body 72.

  The first slit 76A is formed about twice as wide as the second slit 76B. Here, when the drainage lid 70 is placed on the drainage basin 106 of FIG. 5 and the drainage is allowed to flow, the inflow area flowing into the drainage basin 106 from the first slit 76A is from the second slit 76B into the drainage basin 106. It becomes larger than the inflow area. For this reason, the drainage flowing into the drainage basin 106 from the first slit 76A becomes the mainstream, and is led to the right side from the center line CL of the lid 72, and a counterclockwise swirling flow is generated around the center of the drainage basin 106. Occur.

  Since the drainage flows into the drainage basin 106 from the slit 76, it is not necessary to form a gap between the outer periphery of the lid 72 and the opening edge 106A of the drainage basin 106.

  The first to third embodiments of the present invention have been described above. However, the present invention is not limited to such embodiments, and the first to third embodiments may be used in combination. Of course, various embodiments can be implemented without departing from the scope of the invention. For example, the dent amounts of the recesses 20 formed on the four sides of the lid body 14 may be different dent amounts. In this case, the amount of recessed portion 20 formed on the bathtub side where the amount of drainage is relatively small is increased, and the amount of recessed portion 20 formed on the side of the washing place where the amount of discharged water is relatively small is reduced to flow into drainage basin 106. The amount of waste water to be discharged can be made uniform, and a smooth swirling flow C can be generated.
