Description

  The present invention relates to a drain outlet structure provided with a collecting member, and more specifically, to a collecting member provided with a guide structure that guides and forms a flow of drainage to a collecting portion for the purpose of improving cleaning properties and the like. In order to stabilize the flow of drainage that is guided and formed by the guide structure, a trapping structure that closes the gap between the collection member and the drain port is provided to prevent the occurrence of turbulence, The present invention relates to a drain outlet structure provided with a member.

Conventionally, in order to treat the drainage generated on the floor of the bathroom, and inside the tank body such as a sink, a wash basin, and a bathtub, a drain outlet is provided on the floor surface and the bottom surface of the tank body. A method of discharging waste water to the sewage side through a drain pipe constituted by a pipe body or the like is widely known. Drainage from this tank is contaminated with dust, such as hair and wrinkles, and if it flows directly from the drain outlet to the drainage pipe, the hair, dust, etc. accumulates inside the drainage pipe, or on the inner surface of the drainage pipe. There arises a problem that the tube clogs due to adhesion. For this reason, there is a drain outlet collection structure in which a collecting member that collects dust etc. is arranged at the drain outlet, and after removing the dust etc. from the drainage, the drainage flows into the drainage pipe on the downstream side. Conventionally adopted.
Particularly in recent years, the collection member is provided with a guide structure made up of a non-water-permeable wall surface or standing wall so that hair, dust, etc. concentrate and accumulate on the collection portion provided in the collection member, The collection structure of drain outlets designed to improve cleanability is increasing.
Below, the prior art example of the drain outlet structure provided with the collection member is demonstrated.

The drain outlet structure provided with the collection member described in the first conventional example described in Patent Literature 1 is disposed on the floor surface of the bathroom described below, the drain port provided on the floor surface, and the drain port. It is comprised from members, such as a collecting member.
The bathroom floor is a so-called washroom floor where the user of the bathroom is washing the body, and is provided with a slight gradient, which forms a depression at the lowest position on the floor. A drainage trap, which will be described later, is attached to the recessed portion.
The drain trap is a member that is attached and fixed to a recessed portion on the floor surface of the bathroom. A drain port that is a circular opening is provided above the drain trap, and drainage that flows from the drain port is routed through a pipe in the floor space. It is configured to discharge to the sewage side. In addition, a sealing part is formed on the flow path inside the drain trap so as to form a sealed water that is a reservoir of drainage. By this sealing part, a part of the drain flow path in the drain trap is always full. In this state, odors and pests are prevented from flowing back from the sewage side to the indoor side.
A collection member is a member which collects dust, such as hair in drainage, and is arranged at a drain outlet.
The collection member will be described in detail. A frame portion having an arc shape, a concave portion formed in the frame portion, a collection portion having a plurality of drainage holes for drainage in its entirety, and an outward direction from the frame portion And a handle portion formed to be extended.

In a state where a drain trap is attached to the hollow portion of the bathroom and a collecting member is disposed at the drain port, waste water generated on the floor surface of the bathroom is discharged to the sewage side as follows.
When drainage is generated on the floor of the bathroom, such as when the user of the bathroom is washing the body, the drainage passes on the floor of the bathroom and flows from the recessed portion to the drain outlet side.
The wastewater that has flowed onto the collection member flows into the collection unit beyond the frame, passes through the drainage hole from the drainage hole of the collection unit, and is discharged to the sewage side through the drainage trap and the underfloor piping. .
The collection member is provided with a handle, and when cleaning it is necessary to hold the handle and take out the collection member from the drain and discard the dust in the collection unit. This makes it very easy to take out the dust.

Next, a conventional example described in Patent Document 2 will be described. The drain port structure provided with the collecting member of the second conventional example described in Patent Document 2 is disposed on the floor surface of the bathroom described below, the drain port provided on the floor surface, and the drain port. It consists of members, such as a collection member.
The bathroom floor is a so-called washroom floor where the user of the bathroom is washing the body, and is provided with a slight gradient, which forms a depression at the lowest position on the floor. A drainage trap, which will be described later, is attached to the recessed portion.
The drain trap is a member that is attached and fixed to a recessed portion on the floor surface of the bathroom. A drain port that is a circular opening is provided above the drain trap, and drainage that flows from the drain port is routed through a pipe in the floor space. It is configured to discharge to the sewage side. In addition, a sealing part is formed on the flow path inside the drain trap so as to form a sealed water that is a reservoir of drainage. By this sealing part, a part of the drain flow path in the drain trap is always full. In this state, odors and pests are prevented from flowing back from the sewage side to the indoor side.
A collection member is a member which collects dust, such as hair in drainage, and is arranged at a drain outlet.
The collecting member will be described in detail. A collecting portion having a concave shape and having a plurality of drainage holes for drainage on the bottom surface, and a rod that continuously protrudes from the upper edge of the collecting portion along the peripheral edge in a substantially horizontal direction. And a standing wall portion suspended from the upper surface of the collar portion.
The eaves portion includes a drainage introduction portion configured by a wall surface portion having no opening from the outer edge toward the collection portion, and an outflow portion including a drainage hole group for discharging wastewater that has overflowed the collection portion, The standing wall portion guides and forms the flow of the waste water so that the waste water flowing from the outside of the collecting member to the collecting portion flows along the drain introduction portion and hardly passes through the outflow portion.
That is, a drainage introduction part consisting of a wall surface without an opening that forms a drainage flow path from the outer edge of the buttock toward the collection part, and a flow in a direction along the drainage introduction part by restricting the flow direction of the drainage. A guide structure is formed with the standing wall portion to be formed.
Further, the drainage introduction part is formed so as to join the collection part from the outer edge part of the collar part toward the tangential direction of the planar view collection part. For this reason, the waste water flowing along the guide structure flows into the collecting portion from the tangential direction of the collecting portion.

In a state where a drain trap is attached to the hollow portion of the bathroom and a collecting member is disposed at the drain port, waste water generated on the floor surface of the bathroom is discharged to the sewage side as follows.
When drainage is generated on the floor of the bathroom, such as when the user of the bathroom is washing the body, the drainage passes on the floor of the bathroom and flows from the recessed portion to the drain outlet side.
The drainage that has flowed onto the collecting member is formed by the guide structure consisting of the drainage introduction part and the standing wall part, so that the flow passes from the outer edge of the buttock only through the drainage introduction part toward the collection part. It passes through the drainage hole from the drainage hole of the collecting part, and is discharged to the sewage side through the drainage trap and underfloor piping.
Since the drainage flows along the guide structure, the drainage flows in from the tangential direction of the collection unit, and thus the drainage flow is formed so that a vortex is wound in the collection unit. As a result, the dust in the waste water is collected inside the collecting part, particularly in the central part of the vortex, and the dust can be easily taken out during cleaning.
In addition, when the amount of drainage is large and the wastewater that has flowed into the collection section overflows the collection section, the drainage is discharged from the outflow section on the buttock into the drainage outlet, and can be quickly discharged during large-scale drainage. It is configured as follows.

JP 2000-34760 A JP 2009-167783 A

The drain port structure having the conventional collecting member configured as described above has the following problems.
In the above-described conventional example, when the collecting member is arranged at the drain port, the collecting member is taken out from the drain port for cleaning. It is formed by providing a slight gap as play between the outer peripheral surface of the member.
If there is a configuration that does not particularly manage the flow of drainage of the collecting member as in the first conventional example, there is no particular problem even if such a gap portion exists.
However, as in the case of the second conventional example, in the case of the drainage port collecting structure provided with a guide structure and managing the drainage flow, if the gap portion is provided in this way, the drainage flow is affected. There is a case.
More specifically, the way of drainage constituted by the guide structure is to pass from the bottom surface of the depression part, beyond the outer edge of the collar, through the drainage introduction part, and flow into the collection part from the tangential direction. This creates a vortex and improves cleanability.
However, when drainage flows along the gap portion described above, the gap is narrow, so the flow rate of drainage water passing through becomes extremely high (for example, the cross-sectional area of the drainage channel at the gap portion and the portion above it). If the ratio is 1: 3, the drainage speed is three times higher in the gap portion than in the upper portion).
When a part of the drainage that passes through the gap part flows into the drainage introduction part from the bottom of the hollow part beyond the outer edge of the collar part, the drainage flow is disturbed by interfering with the drainage flow.
Of course, this turbulence does not significantly change the way the drainage flows, for example, a backflow that causes the dust in the collection part to flow into the depression, but it is provided to improve the cleaning properties as described above. Further, there is a problem in that the suitable flow of the guide structure is disturbed, the formation of vortices in the collecting part is hindered, and it is impossible to collect dust in the collecting part.
The present invention was invented in view of the above problems, and in the drain outlet structure provided with the collecting member, when the collecting member is provided with a guide structure for guiding and forming the flow of drainage, the guide structure By preventing the flow of the waste water from being disturbed by the waste water passing through the gap portion between the drain port and the collecting member, the cleaning property of the collecting member is improved.

The notch portion 4 a is a notch groove provided so as to reach from the outer edge of the cover portion 4 to the gap portion S between the collecting member 2 and the drain port 1 when the collecting member 2 is attached to the drain port 1. When the construction is completed, the gap portion S between the collecting member 2 and the drain port 1 is opened only in the cutout portion 4a. For this reason, when the water level of the remaining water on the bottom surface or the floor surface of the drainage tub is lower than the upper surface of the cover portion 4, the gap portion between the collection member 2 and the drain port 1 from the cutout portion 4 a. It passes through S and is discharged into the drain port 1.

The drain trap and the collecting member 2 configured as described above are constructed in the bathroom as follows. Although not specifically described in detail, water-tight connection by bonding or packing is performed for a portion requiring particularly water-tight connection such as a connection portion of a pipe.
First, the flange member 13 is inserted into the mounting hole B2 of the bathroom, and the lower surface of the flange portion 13a is disposed so as to contact the upper surface of the mounting hole B2.
Next, after connecting the discharge port 12a of the trap body 12 to the underfloor pipe, the female screw of the trap body 12 and the male screw of the flange member 13 are screwed together, and the mounting hole is formed between the lower surface of the flange portion 13a and the upper surface of the trap body 12 Fix so that the periphery of B2 is pinched.
Next, the deodorizing cylinder 14 is inserted into the drain port 1, and the upper end portion of the deodorizing cylinder 14 is connected to the drain port 1 in a watertight manner.
Next, the collecting member 2 is connected and fixed to the drain port 1 of the drain trap.
In this case, the convex portion 13b of the drain port 1 is matched with the open portion below the fitting groove portion 6, the collecting member 2 is lowered, and the lower surface of the cover portion 4 is brought into contact with the periphery of the drain port 1 to be fitted. The collection member 2 is rotated along the groove 6. The collection member 2 is fitted and fixed to the drain port 1 by the protrusion 13 b getting over the protrusion 6 a on the fitting groove 6. That is, by combining with the fitting groove portion 6 of the collecting member 2 and the convex portion 13 b of the drain port 1, it functions as a lock mechanism for fixing the collecting member 2 to the drain port 1. When the collection member 2 is rotated, the work for rotating is extremely easy by holding the anti-slip portion 9 and performing the work.
As described above, the drain trap and the collection member 2 are installed and installed in the bathroom.

  In the bathroom constructed as described above, when drainage is generated on the bathroom floor B by washing the body or head of the bathroom, the drainage passes over the bathroom floor B, It flows from the hollow B1 to the drain port 1 side. The flow is detailed as follows.

  If a large amount of drainage has reached the depression B1 and is accumulated on the depression B1 far above the upper edge of the standing wall 8, the drainage flow is simply all drain holes 11a on the collecting member 2. Specifically, the drainage is performed through all of the drainage hole 11a on the collection part 3, the drainage small hole 11c on the drainage guidance part 7, the overflow drainage hole 11b on the upper surface of the standing wall part 8, and the cutout part 4a. In this state, turbulent flow is generated in the depression, and the drainage simply flows into the drain outlet 1 from each hole, and the function of rectification based on the guide structure hardly functions. Even if dust or hair is temporarily collected on the drainage holes 11a, etc., it is not swollen by the turbulent flow and only rises.

Although the amount of drainage that has reached the recess B1 is relatively small or large, drainage is performed through the opening of the drainage hole 11a and the like of the collecting member 2, and the water level of the drainage on the recess B1 is the upper end of the standing wall 8 In the case of the water level from the vicinity to the level slightly below the upper end of the standing wall portion 8 or below, a groove portion formed on the drainage guiding portion 7 and between the standing wall portions 8 from the periphery of the collecting member 2 The flow of the wastewater that passes through and flows toward the collection part 3 is induced and formed.
The main drainage flow at this time is as follows.
Of the flow from the recessed portion B1 toward the drain port 1, the flow from the outer wall surface portion 8a of the standing wall portion 8 of the collecting member 2 to the drain port 1 is a standing wall. The flow is changed by the outer wall surface portion 8 a of the portion 8, and the flow is directed to one of the two drainage guiding portions 7 along the outer wall surface portion 8 a of the standing wall portion 8.
Of the flow from the hollow portion B1 toward the drain port 1, the flow from the drainage guiding portion 7 of the collecting member 2 toward the drainage port 1, or the flow from the drainage guiding portion 7 after flowing along the outer wall surface portion 8 a of the standing wall portion 8. The flow toward the drainage port 1 passes from the outer edge of the drainage guidance unit 7 over the drainage guidance unit 7 and reaches the collection unit 3. In addition, since the both sides | surfaces of the drainage guidance part 7 are provided with the introduction wall part 8c or the vortex formation wall part 8b of the standing wall part 8, and drainage does not exceed this wall surface, drainage is the shape of the drainage guidance part 7. Flowing along. The drainage that has flowed into the collection unit 3 flows into the collection unit 3 having a circular shape in plan view and a concave shape in side view, and the drainage of the drainage introduction unit flows from the circular tangential direction in plan view. The drainage swirls within 3, and the dust, such as hair, in the drainage collects along the flow of the drainage. A part of the drainage is discharged from the drainage small hole 11 c on the drainage guiding unit 7, but most of the drainage is discharged from the drainage hole 11 a on the collecting unit 3. Finally, when the drainage is completed, the dust such as the hair in the drainage is collected in a lump on the ribs 10 provided on the collection unit 3 and collected. Draining at 2 is completed.
In the case where the rib 10 is not provided, the dust is collected by sticking to the upper surface of the collecting member 2, and thus it is difficult to take out, but in this embodiment, as described above, Since it stays on the line of the protruding rib 10 and is not collected so as to stick to the surface, it is very easy to take out.
As described above, in the present embodiment, the drainage guiding unit 7 and the standing wall unit 8 guide the flow of drainage to the collecting unit 3 to flow in the tangential direction of the collecting unit 3 in a plan view. That is, in the present embodiment, the drainage guiding portion 7 and the standing wall portion 8 function as a guide structure that guides the flow of drainage to the collecting portion 3.

  In addition to the above-described drainage flow that passes through the drainage hole 11a, drainage small hole 11c, or overflow drainage hole 11b provided on the upper surface of the collecting member 2, and flows into the drainage port 1, the notch 4a There is also a flow of waste water that passes through the drain port 1. Since this drainage flow is not large in the opening area of the notch 4a, the amount of the drainage is never large, and the drainage flow is hardly affected. On the other hand, when the drainage on the recessed portion B1 is almost completed and the water level becomes lower than the thickness in the vertical direction of the cover portion 4, the remaining water on the recessed portion B1 is discharged, and water drops on the recessed portion B1. To prevent residual water from forming.

  As described in the paragraphs 0019 to 0021, the waste water that has flowed into the drain port 1 passes through the inside of the deodorizing cylinder 14 and accumulates in the sealed water bottle portion 12b inside the trap body 12, and then the sealed water bottle. Exceeding the upper edge of the portion 12b, the water is discharged from the discharge port 12a to the sewage side through the underfloor piping. At this time, since the drainage flow path from the inside of the deodorizing cylinder 14 to the upper edge of the sealed water bottle portion 12b is filled with water, odors and pests cannot pass through. Such a backflow is prevented.

When dust such as hair accumulates in the collecting part 3 of the collecting member 2 due to use of the bathroom, the fixing by the rotation lock between the drain port 1 and the collecting member 2 is released and collected from the drain port 1 The member 2 is removed. That is, by rotating the collecting member 2 in the opposite direction to the fitting state, the fitting for fixing the collecting member 2 to the drain port 1 can be released, and the collecting member 2 can be taken out from the drain port 1. Become. When the collection member 2 is rotated, the work for rotating is extremely easy by holding the anti-slip portion 9 and performing the work.
Then, when the collection member 2 taken out from the drain port 1 is inverted upside down, the dust on the collection unit 3 falls easily and can be easily cleaned.
This is because the dust is collected on the protrusion rib 10, and the dust and the collecting member 2 are in line contact, there is no sticking due to surface contact, and the dust can be easily taken out from the collecting member 2. Because it can.
Furthermore, if necessary, the deodorizing cylinder 14 can be removed from the trap body 12 and the interior and members of the drain trap can be removed for easy cleaning.
Each removed member can be attached in the same manner as at the time of construction.

  Furthermore, in the drain port structure having the closing structure configured as described above, the gap space S between the drain port 1 and the collecting member 2 other than the notch 4a is blocked by the cover portion 4 including the cover portion 4. Being done. For this reason, as in the second conventional example, the drainage flowing through the gap portion S between the drainage port 1 and the collecting member 2 causes the flow of drainage by the guide structure, that is, drainage that flows into the drainage guiding portion 7 from the depression B1. As a result, the improvement of the cleaning performance in the collecting portion 3 of the collecting member 2 described above is surely performed.

The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
