Summary of the Invention

Problems to be Solved by the Invention

[0004] In the drain outlet mesh member as shown in Patent Document 1 above, drainage containing foreign matter often flows through. When such snagging of foreign matter or accumulation of dirt occurs, the mesh becomes clogged and the drainage performance deteriorates. Therefore, in the drain outlet mesh member, in addition to suppressing the overflow of drainage, it is also required to have a specification that makes it easy to detect the snagging of foreign matter and the accumulation of dirt.

[0005] In view of the above facts, an object of the present disclosure is to provide a drain outlet mesh member that makes it easy to detect the snagging of foreign matter and the accumulation of dirt.

Means for Solving the Problems

[0006] The drain outlet mesh member of the first aspect includes a cylindrical main body portion that can be attached to a cylindrical lateral extension portion provided at the bottom of the drain outlet member, a drain guide portion formed at an end of the main body portion, which is inclined with respect to the vertical direction in a state where the main body portion is attached to the lateral extension portion, and is made visible when the drain outlet member is viewed from the upper side in the vertical direction, and a plurality of through holes formed in the drain guide portion.

[0007] When the drain outlet mesh member of the first aspect is used, the drain that has flowed into the drain outlet member flows out to the lateral extension portion through the plurality of through holes formed in the drain guide portion and the main body portion. This drain guide portion is made visible when viewed from the upper side in the vertical direction. Therefore, even if foreign matter gets caught or dirt accumulates in the through holes, these are easy to discover. Thereby, clogging of the drain outlet mesh member can be suppressed.

[0008] In the drain outlet mesh member of the second aspect, when viewed from a direction along the axial direction of the lateral extension portion, the drain guide portion is formed within a range that overlaps with the inside of the lateral extension portion.

[0009] In the drain outlet mesh member of the second aspect, the drain guide portion is formed within a range that overlaps with the cross-section of the lateral extension portion. Therefore, the drain is guided into the lateral extension portion through the through holes formed inside the lateral extension portion when viewed from the axial direction of the lateral extension portion. Thereby, it is difficult for the drain to stagnate within the lateral extension portion.

[0010] On the other hand, when the drain is guided from the outside of the lateral extension portion into the lateral extension portion, a water flow is likely to occur toward the inner side in the radial direction of the lateral extension portion, and stagnation is likely to occur near the inner wall of the lateral extension portion.

[0011] In the drain outlet mesh member of the third aspect, the through holes penetrate the drain guide portion along the axial direction of the main body portion.

[0012] In the drain outlet mesh member of the third aspect, the through holes are formed along the axial direction of the main body portion. Thereby, the drain is likely to be rectified along the axial direction of the main body portion within the through holes. Thereby, the drain is likely to flow through the main body portion.

[0013] In the drain outlet mesh member of the fourth aspect, the through hole has a polygonal shape composed of a plurality of sides, and the angle formed by one side and the other side is set to an obtuse angle.

[0014] In the drain outlet mesh member of the fourth aspect, the through hole has a polygonal shape composed of a plurality of sides, and the angle formed by one side and the other side is an obtuse angle, in other words, an angle exceeding 90 degrees. Therefore, compared with the case where the corner of the through hole is an acute angle of 90 degrees or less, foreign matter in the drainage is less likely to be caught on the corner.

[0015] In the drain outlet mesh member of the fifth aspect, a through hole is further formed on the side surface of the main body portion.

[0016] In the drain outlet mesh member of the fifth aspect, a through hole is further formed on the side surface of the main body portion. As a result, the drainage volume can be increased.

Advantages of the Invention

[0017] According to the present invention, it is easy to detect the catching of foreign matter and the accumulation of dirt.

Mode for Carrying Out the Invention

[0019] Hereinafter, the drain outlet mesh member 50 according to an embodiment of the present disclosure will be described with reference to the drawings. Components denoted by the same reference numerals in the respective drawings mean the same components. However, unless otherwise specified in the specification, each component is not limited to one, and a plurality of them may exist.

[0020] In addition, descriptions of overlapping configurations and reference numerals in the respective drawings may be omitted. Note that the present disclosure is not limited to the following embodiments, and appropriate modifications can be made, such as omitting configurations, replacing with different configurations, or combining one embodiment and various modification examples within the scope of the object of the present disclosure.

[0021] <Siphon Drainage System> Prior to the description of the drain outlet mesh member 50 according to an embodiment of the present disclosure, an example of the siphon drainage system 10 to which the drain outlet mesh member 50 is applied will be described.

[0022] The siphon drainage system 10 is a drainage system that efficiently discharges drainage from plumbing fixtures by utilizing the siphon force. In the present embodiment, an example in which the siphon drainage system is used in an apartment building composed of multiple floors will be described. Note that the siphon drainage system is preferably used in an apartment building, but can also be used in a detached house or a factory other than an apartment building.

[0023] As shown in FIG. 1, the siphon drainage system 10 according to the present embodiment includes a drain riser 12 that drains water downward. This drain riser 12 extends in the vertical direction (up and down direction) of the apartment building and penetrates the floor slabs 14 of each floor of the apartment building.

[0024] In each household on each floor of the apartment building, there is provided a plumbing fixture 16 for draining water. The plumbing fixture 16 is constituted by, for example, a kitchen sink. Note that the plumbing fixture 16 is not limited to a kitchen sink and may be constituted by any one of a washbasin, a washing machine, a unit bathroom, a toilet, etc.

[0025] A drain port member 18 is attached to a drain port 17 formed at the bottom of the plumbing fixture 16, and on the downstream side in the drainage direction of the drain port member 18, it is connected to a pipe 20, an S-trap 22 for preventing backflow of foul odors and gases, etc., a pipe 24, and a siphon drain pipe 26.

[0026] The siphon drain pipe 26 has a horizontal pipe 28 that is installed horizontally without a gradient on the floor slab 14 and extends horizontally, and a vertical pipe 30 that communicates with this horizontal pipe 28 and extends downward along the drain riser 12.

[0027] Note that the horizontal pipe 28 may have a slight gradient or reverse gradient, and may be configured to be inclined and arranged horizontally. The vertical pipe 30 is connected to a junction joint 32 arranged in the drain riser 12 and communicates with the drain riser 12 via the junction joint 32.

[0028] The horizontal pipe 28 flows the drainage from the pipe 24 horizontally, and the vertical pipe 30 generates a siphon force by allowing the drainage from the horizontal pipe 28 to flow down. A siphon force directed in the drainage direction acts on the drainage in the horizontal pipe 28 due to the energy of the siphon head Hs generated in the vertical pipe 30.

[0029] Also, if the horizontal pipe 28 and the vertical pipe 30 are made thinner, the drainage will be in a full water state and a siphon force will be easily generated, while the drainage treatment capacity will decrease. Therefore, the inner diameters of the horizontal pipe 28 and the vertical pipe 30 are set in consideration of the ease of generating a siphon force and the required drainage treatment capacity.

[0030] <Drain port member> The drain outlet member 18 is a bowl-shaped water receiving member fixed to a drain outlet 17 formed at the bottom of the plumbing fixture 16. At the upper end of the drain outlet member 18, a flange 38 that projects radially outward is formed. This flange 38 is locked to the edge of the drain outlet 17, and the drain outlet member 18 is fixed to the drain outlet 17. Also, a packing 42 is provided between the flange 38 and the edge of the drain outlet 17 to prevent water leakage.

[0031] As shown in FIG. 2, the drain outlet member 18 includes a cylindrical portion 18A, a bottom portion 18B that forms the bottom surface of the cylindrical portion 18A, and a lateral extension portion 18C connected to the lowermost portion of the cylindrical portion 18A.

[0032] The cylindrical portion 18A is a cylindrical part whose axial direction is along the vertical direction when the drain outlet member 18 is mounted to the drain outlet 17, and the above-described flange 38 is formed at the upper end portion. The bottom portion 18B is formed at the lower end portion of the cylindrical portion 18A, and is a portion that receives the drain water flowing into the drain outlet member 18 and guides it to the lateral extension portion 18C.

[0033] The lateral extension portion 18C is a cylindrical part whose axial direction is along the horizontal direction (or the direction along the water gradient) when the drain outlet member 18 is mounted to the drain outlet 17. One end thereof is connected to the cylindrical portion 18A, and the other end is connected to the pipe 20 shown in FIG. 1. In FIG. 2, the drain outlet 17 and the pipe 20 are not shown, and only the drain outlet member 18 and the drain outlet mesh member 50 are shown.

[0034] At the end of the lateral extension portion 18C on the side of the cylindrical portion 18A, a locking groove 19 for locking the locking pieces H1 and H2 of the drain outlet mesh member 50 is formed.

[0035] <Drain outlet mesh member> As shown in FIG. 3, the drain outlet mesh member 50 includes a main body portion 52 and a drain guiding portion 54.

[0036] (Main body portion) The main body portion 52 is a cylindrical portion that can be attached to the lateral pulling portion 18C (see FIG. 2) of the drain outlet member 18. The main body portion 52 is the portion surrounded by the dashed-dotted line in FIG. 3, and a drain guiding portion 54 is formed at one end thereof.

[0037] The main body portion 52 includes an upper wall 52A, a side wall 52B, and a lower wall 52C. The outer peripheral surfaces of the upper wall 52A, the side wall 52B, and the lower wall 52C are each shaped to be in contact with the inner peripheral surface of the lateral pulling portion 18C (see FIG. 2) of the drain outlet member 18. Also, the axial direction of the main body portion 52 coincides with the axial direction of the lateral pulling portion 18C.

[0038] The upper wall 52A is a portion that forms the upper end portion (the upper surface of the main body portion 52) of the cylindrical main body portion 52, and is formed in a convex shape upward. On the upper wall 52A, a locking piece H1 that protrudes upward along the circumferential direction is formed.

[0039] The side wall 52B is a portion that forms the central portion in the vertical direction (the side surface of the main body portion 52) of the cylindrical main body portion 52, and is formed in a flat plate shape along the vertical direction. On the side wall 52B, a locking piece H2 that protrudes laterally (outward) along the vertical direction is formed.

[0040] A through hole 62 is formed in the side wall 52B. The through hole 62 has a polygonal shape composed of a plurality of sides, and the angle formed by one side and the other side is set to an obtuse angle. Specifically, the through hole 62 has a hexagonal shape, and the angle formed by one side and the other side is set to 120°. Also, the through hole 62 penetrates the side wall 52B along a direction orthogonal to the axial direction of the main body portion 52.

[0041] The lower wall 52C is a portion that forms the lower end portion (the lower surface of the main body portion 52) of the cylindrical main body portion 52, and is formed in a convex shape downward.

[0042] Slits S1 are formed between the upper wall 52A and the side wall 52B, and between the side wall 52B and the lower wall 52C. The slit S1 is a gap that extends in the axial direction of the main body portion 52, and is open at the end of the main body portion 52 on the side opposite to the drain guiding portion 54.

[0043] By providing the slit S1, the upper wall 52A is made elastically deformable in the vertical direction, and the side wall 52B is made elastically deformable in the horizontal direction. Thereby, the locking pieces H1 and H2 can be locked to the locking groove 19 of the drain port member 18 shown in FIG. 2.

[0044] (Drain guiding part) The drain guiding part 54 is an inclined part formed at the end of the main body part 52. As shown in FIG. 4B, the drain guiding part 54 is inclined with respect to the vertical direction in a state where the main body part 52 is attached to the lateral pulling part 18C.

[0045] As shown in FIG. 2, the drain guiding part 54 is visible when the drain port member 18 is viewed from the upper side in the vertical direction (arrow P1). As shown in FIG. 4B, a plurality of through holes 64 are formed in the drain guiding part 54. "Visible" means that the surface of the drain guiding part 54 where the through holes 64 are formed and the through holes 64 are visible.

[0046] As shown in FIG. 3, the through hole 64 is in a polygonal shape composed of a plurality of sides, and the angle formed by one side and the other side is set to an obtuse angle. Specifically, the through hole 64 is in a hexagonal shape, and the angle formed by one side and the other side is set to 120°. Also, as shown in FIG. 4B, the through hole 64 penetrates the drain guiding part 54 along the axial direction of the main body part 52.

[0047] Note that "the angle formed by one side and the other side is 120°" is the angle viewed from the direction along the axial direction (the direction indicated by the dashed-dotted line CL) of the main body part 52 and the lateral pulling part 18C. That is, as shown in FIG. 4A, when the drain guiding part 54 is viewed from the direction along the axial direction of the main body part 52 and the lateral pulling part 18C, the through hole 64 is visually recognized as a regular hexagon.

[0048] Note that chamfers R are formed at the open ends of the through holes 64, which are the open ends outside the drain port mesh member 50. Similarly, as shown in FIG. 3, chamfers R are formed at the open ends of the through holes 62, which are the open ends outside the drain port mesh member 50.

[0049] As shown in FIG. 5, when viewed from the direction along the axial direction of the lateral drawing portion 18C (arrow P2), the drain guiding portion 54 is formed within a range overlapping the inside of the lateral drawing portion 18C. That is, the drain guiding portion 54 is disposed within the region ER between the inner peripheral walls of the lateral drawing portion 18C. Further, the through hole 64 is also formed within a range overlapping the inside of the lateral drawing portion 18C.

[0050] <Function and Effect> When the drain port mesh member 50 according to the embodiment of the present disclosure is used, the drain that has flowed into the drain port member 18 flows out to the lateral drawing portion 18C through the plurality of through holes 64 and the main body portion 52 formed in the drain guiding portion 54.

[0051] This drain guiding portion 54 is visible when viewed from the upper side in the vertical direction as indicated by the arrow P1 in FIG. 2. For this reason, even if foreign matter gets caught or dirt accumulates in the through hole 64, these are easy to discover. Thereby, clogging of the drain port mesh member 50 can be suppressed.

[0052] Further, in this drain port mesh member 50, as shown in FIG. 5, the drain guiding portion 54 is formed within a range overlapping the cross section of the lateral drawing portion 18C (within the region ER). For this reason, the drain is guided into the lateral drawing portion 18C through the through hole 64 formed inside the lateral drawing portion 18C when viewed from the axial direction of the lateral drawing portion 18C as indicated by the arrow W1. Thereby, it is difficult for the drain to stay within the lateral drawing portion 18C.

[0053] On the other hand, for example, when the drain guiding portion 55 is also formed outside the range overlapping the cross section of the lateral drawing portion 18C as in the drain port mesh member 51 shown in FIG. 6, the drain is guided into the lateral drawing portion 18C from the outside of the lateral drawing portion 18C as indicated by the arrow W2, and a water flow is likely to occur toward the radially inner side of the lateral drawing portion 18C, and stagnation is likely to occur near the inner wall of the lateral drawing portion 18C.

[0054] In addition, the drain port mesh member in the present disclosure may include such a drain port mesh member 51. That is, the drain port mesh member in the present disclosure may be formed outside the range overlapping the cross-section of the lateral drawing portion 18C. Further, the through-hole 64 may be formed outside the range overlapping the cross-section of the lateral drawing portion 18C. Since the drain guide portion 55 of the drain port mesh member 51 is also visible when viewed from the upper side in the vertical direction, clogging of the drain port mesh member 51 can be suppressed.

[0055] Further, in the drain port mesh member 50 in the present disclosure, as shown in FIG. 4B, the through-hole 64 of the drain guide portion 54 is formed along the axial direction of the main body portion 52 (and the axial direction of the lateral drawing portion 18C shown in FIG. 2). Thereby, drainage is likely to be rectified along the axial direction of the main body portion 52 (and the lateral drawing portion 18C) within the through-hole 64. Thereby, drainage easily flows within the main body portion 52 and the lateral drawing portion 18C.

[0056] Further, in the drain port mesh member 50 in the present disclosure, as shown in FIG. 3, the through-hole 64 has a polygonal shape formed of a plurality of sides, and the angle formed by one side and the other side is set to an obtuse angle, in other words, an angle exceeding 90 degrees. For this reason, foreign matter in the drainage is less likely to be caught at the corners compared to the case where the corners of the through-hole 64 are acute angles of 90 degrees or less.

[0057] Further, in the drain port mesh member 50 in the present disclosure, a through-hole 62 is further formed in the side wall 52B formed on the side surface of the main body portion 52. Thereby, clogging is less likely to occur in the drain port mesh member 50 compared to the case where the through-hole 62 is not formed in the side wall 52B.

[0058] <Other Embodiments> In the above embodiment, it is assumed that the through-hole 64 penetrates the drain guide portion 54 along the axial direction of the main body portion 52, but the embodiment of the present disclosure is not limited to this. For example, the through-hole of the present disclosure may penetrate the drain guide portion 54 in a direction intersecting the axial direction of the main body portion 52.

[0059] Further, in the above embodiment, the through hole 64 is formed in a polygonal shape composed of a plurality of sides, and the angle formed by one side and the other side is set to an obtuse angle. However, the embodiment of the present disclosure is not limited thereto.

[0060] For example, the through hole of the present disclosure may be circular, or may have a shape including an acute angle such as a triangle or a quadrilateral shape. Further, even when the through hole has a shape that does not include an acute angle, in addition to a hexagon, it may have a pentagonal shape or a polygonal shape with seven or more sides.

[0061] Further, in the above embodiment, the through hole 62 is also formed in the side wall 52B. However, the embodiment of the present disclosure is not limited thereto. This through hole 62 may be omitted. Thus, the present disclosure can be implemented in various modes.
