At least a portion of the drain pipe 3 is inserted into the drain pipe connection hole 111, so that the drain pipe 3 can be detachably connected to the drain pipe connection hole 111. That is, at least a portion of the drain pipe 3 is inserted into the drain pipe connection hole 111, and the drain pipe 3 is connected to the drain pipe connection hole 111, whereby the drain pipe 3 is connected to the drain pipe connection body 110. can be connected to

Additionally, the drain pipe 3 may be connected to the drain pipe connection portion 100. As the drain pipe 3 is pulled out from the drain pipe connection hole 111, the drain pipe 3 is separated from the drain pipe connection hole 111, and thereby the drain pipe 3 can be separated from the drain pipe connection body 110. Additionally, the drain pipe 3 may be separated from the drain pipe connection portion 100. With this configuration, the drain pipe 3 can be easily connected to the drain pipe connection portion 100 or the drain pipe 3 can be easily separated from the drain pipe connection portion 100. For example, the drain pipe connection hole 111 may be formed perpendicular to the drain pipe connection body 110 so that the top is open. In this case, at least a portion of the drain pipe 3 connected to the lower side of the water use device 2, etc. and extending downward from the water use device 2, etc. is connected to the drain pipe through the open upper part of the drain pipe connection hole 111. By being inserted into the hole 111, it can be easily connected to the drain pipe connection hole 111. In addition, at least a part of the drain pipe 3 inserted and connected to the drain pipe connection hole 111 is pulled out from the drain pipe connection hole 111 through the open upper part of the drain pipe connection hole 111. Can be easily separated. However, the direction in which the drain pipe connection hole 111 is formed in the drain pipe connection body 110 and the portion where the drain pipe connection hole 111 is opened are not particularly limited.

Meanwhile, a flow guide space 112 may be formed in the drain pipe connection body 110. The flow guide space 112 may be connected to the drain pipe connection hole 111 and the flow connection hole 201 formed in the support portion 200 to be described later. In addition, the flow connection hole 201 of the support part 200 may be connected to the flow space 311 formed in the sewer pipe connection body 310, which will be described later, included in the sewer pipe connection part 300. With this configuration, water discharged from the drain pipe 3 connected to the drain pipe connection hole 111 can flow into the flow guide space 112. Additionally, water flowing into the flow guide space 112 may pass through the flow connection hole 201 of the support part 200 and flow into the flow space 311 of the sewer pipe connection part 300.

Referring to Figures 2 and 6, the drain pipe connection portion 100 may further include a drain pipe support member 120. The drain pipe support member 120 may be placed in the drain pipe connection hole 111 to support the drain pipe 3 inserted into the drain pipe connection hole 111 of the drain pipe connection body 110. In addition, a support protrusion 111-1 having a step shape is formed on the inner peripheral surface of the drain pipe connection body 110 to support the drain pipe support member 120. In this case, a communication hole 121 is formed in the drain pipe support member 120 to allow water discharged from the drain pipe 3 connected to the drain pipe connection hole 111 to flow into the drain pipe connection body 110. For example, water discharged from the drain pipe 3 may pass through the communication hole 121 of the drain pipe support member 120 and flow into the flow guide space 112. Meanwhile, the drain pipe connection part 100 may further include a filter member 130. The filter member 130 may be placed in the drain pipe connection hole 111 so as to contact the drain pipe support member 120. With this configuration, the filter member 130 can be positioned between the drain pipe 3 and the drain pipe support member 120, thereby preventing foreign substances such as insects from entering the drain pipe 3.

The support portion 200 may support the drain pipe connection portion 100. For example, the support part 200 may have a plate shape. Additionally, a flat connection surface (not shown) may be formed on the drain pipe connection body 110 of the drain pipe connection portion 100. In addition, the connection surface of the drain pipe connection body 110 of the drain pipe connection portion 100 is connected to one surface of the plate-shaped support portion 200 in close contact, so that the support portion 200 can support the drain pipe connection portion 100. In this case, the drain pipe connection portion 100 and the plate-shaped support portion 200 are formed integrally, and the connection surface of the drain pipe connection body 110 of the drain pipe connection portion 100 can be connected to one surface of the support portion 200 in close contact. . However, the configuration of the support portion 200 supporting the drain pipe connection portion 100 is not particularly limited.

Referring to FIGS. 2 to 6 , a flow connection hole 201 may be formed in the support portion 200. The flow connection hole 201 may communicate with the flow space 311 of the sewer pipe connection part 300 and the drain pipe connection part 100. For example, the flow connection hole 201 may be connected to one side of the flow space 311 of the sewer pipe connection part 300 and the flow guide space 112 of the drain pipe connection part 100. With this configuration, water flowing in the flow guide space 112 of the drain pipe connection part 100 can pass through the flow connection hole 201 and flow into the flow space 311 of the sewer pipe connection part 300. For example, the flow connection hole 201 may have a semicircular shape convex downward. However, the shape of the flow connection hole 201 is not particularly limited.

Meanwhile, when the support part 200 has a plate shape, the drain pipe connection part 100 may be connected to one side of the plate-shaped support part 200 and the sewer pipe connection part 300 may be connected to the other side. Additionally, when the sewer pipe connection portion 300 is connected to the sewer pipe 6 embedded in the wall 4, at least a portion of the other surface of the support portion 200 may be in close contact with the wall 4. Accordingly, as shown in FIG. 1, the sewer pipe 6 and the sewer pipe connection portion 300 are not visible from the outside by the support portion 200, and only the drain pipe connection portion 100 and the support portion 200 to which the drain pipe 3 is connected are visible from the outside. Since it is visible from the front, it can be aesthetically pleasing.

One side of the sewer pipe connection part 300 may be supported on the support part 200. For example, the support part 200 is plate-shaped, and the drain pipe connection part 100 may be connected to one surface of the plate-shaped support part 200. Additionally, one side of the sewer pipe connection portion 300 may be connected to and supported on the other side of the plate-shaped support portion 200. In this case, the plate-shaped support part 200 and the sewer pipe connection part 300 are formed as one body, and the sewer pipe connection part 300 can be connected to and supported on the other surface of the support part 200. However, the configuration in which one side of the sewer pipe connection part 300 is supported by the support part 200 is not particularly limited.

The other side of the sewer pipe connection part 300 may be detachably connected to the sewer pipe 6. In this case, the sewer pipe (6) can be buried in the wall (4). More specifically, the sewer pipe 6 is formed in the wall 4 and can be placed in the sewer pipe arrangement hole 5 with one side open and embedded in the wall 4. Additionally, the other side of the sewer pipe connection unit 300 may be detachably connected to the sewer pipe 6 through the open side of the sewer pipe arrangement hole 5. With the other side of the sewer pipe connection 300 connected to the sewer pipe 6 embedded in the wall 4, the drain pipe 3 connected to the water use device 2, such as a washbasin or sink, is connected to the drain pipe of the drain pipe connection 100. By inserting into the hole 111, the drain pipe 3 can be connected to the sewer pipe 6 embedded in the wall 4. Therefore, the drain pipe connecting device (1) according to an embodiment of the present invention can be easily installed, and the drain pipe (3) connected to a water use device (2) such as a washbasin or sink can be connected to a sewer pipe embedded in the wall (4). It can be easily and quickly connected to (6).

The sewer pipe connection part 300 may communicate with the drain pipe connection part 100 so that water flowing into the drain pipe connection part 100 from the drain pipe 3 flows into the sewer pipe 6. This sewer pipe connection part 300 may include a sewer pipe connection body 310 and a water blocking member 320.

A flow space 311 for water to flow may be formed inside the sewer pipe connection body 310. One side of the flow space 311 may be connected to the drain pipe connection hole 111 of the drain pipe connection portion 100. Accordingly, water discharged from the drain pipe 3 connected to the drain pipe connection hole 111 of the drain pipe connection portion 100 may flow into the flow space 311. For example, the drain pipe connection hole 111 of the drain pipe connection portion 100 may be connected to the flow guide space 112 of the drain pipe connection portion 100. Additionally, the flow guide space 112 of the drain pipe connection part 100 may be connected to the flow connection hole 201 of the support part 200. Additionally, one side of the flow space 311 may be connected to the flow connection hole 201 of the support part 200. To this end, the sewer pipe connection body 310 may be connected to the support portion 200 so as to surround the flow connection hole 201. By this configuration, one side of the flow space 311 can be connected to the drain pipe connection hole 111 of the pipe connection part 100. The other side of the flow space 311 may be connected to the sewer pipe 6. When the sewer pipe connection part 300 is connected to the sewer pipe 6 through the open side of the sewer pipe arrangement hole 5 formed in the wall 4, etc., the flow space 311 can be connected to the sewer pipe 6. Additionally, water flowing in the flow space 311 may flow into the sewer pipe 6 embedded in the wall 4 or the like and flow through the sewer pipe 6.

Referring to Figures 1 to 3, a plurality of cut parts 312 are formed on the other side of the sewer pipe connection body 310 to be spaced a predetermined distance apart from each other, and the cut parts 312 extend to the other end of the sewer pipe connection body 310. It may be extended. With this configuration, the other side of the sewer pipe connection body 310 can be split into a predetermined number of parts. For example, on the other side of the sewer pipe connection body 310, four cut portions 312 are formed at a predetermined distance apart from each other and extend to the other end of the sewer pipe connection body 310, so that the other side of the sewer pipe connection body 310 is 4. It can split into four parts. With this configuration, the other side of the sewer pipe connection body 310 can be easily deformed, so the other side of the sewer pipe connection body 310 can be easily connected to the sewer pipe 6. In this case, the width W of the cut portion 312 may increase from one side of the sewer pipe connection body 310 to the other side. With this configuration, deformation of the other side of the sewer pipe connection body 310 can be made easier. Meanwhile, the other side of the sewer pipe connection body 310, which is divided into a predetermined number of parts by the cut portion 312, may be formed of a leaf spring. Due to this configuration, an elastic force can be applied to the other side of the sewer pipe connection body 310, so that the other side of the sewer pipe connection body 310, which has been deformed to be connected to the sewer pipe 6, remains before deformation after being connected to the sewer pipe 6. You can go back.

A diameter reduction portion 313 may be formed on the other side of the sewer pipe connection body 310. The outer diameter of the diameter reducing portion 313 may become smaller toward the other end of the sewer pipe connection body 310. Additionally, the inner diameter of the diameter reducing portion 313 may become smaller toward the other end of the sewer pipe connection body 310. Additionally, the diameter reduction portion 313 may extend to the other end of the sewer pipe connection body 310. With this configuration, the other side of the sewer pipe connection body 310 can be easily inserted into the sewer pipe 6 embedded in the wall 4, etc., so that the other side of the sewer pipe connection body 310 can be easily inserted into the sewer pipe 6 embedded in the wall 4, etc. It can be easily connected to (6). The diameter reduction part 313 may be connected to the fitting jaw part 314, which will be described later.

An insertion portion 314 may be formed on the other side of the sewer pipe connection body 310. The fitting ledge 314 may protrude from the outer periphery of the sewer pipe connection body 310 to form a convex curved surface. Additionally, the outer diameter of the fitting ledge 314 may increase and then decrease as it moves toward the other end of the sewer pipe connection body 310. This insertion portion 314 can be inserted into the sewer pipe 6 when the other side of the sewer pipe connecting body 310 is connected to the sewer pipe 6 embedded in the wall 4 or the like. Therefore, when the other side of the sewer pipe connection body 310 is connected to the sewer pipe 6 embedded in the wall 4, etc., the sewer pipe connection body 310 is not easily separated from the sewer pipe 6 by the insertion protrusion 314. It may not be possible. In this case, the slope of at least a part of the curved surface of the part of the fitting ledge 314 whose outer diameter increases may be greater than the slope of the curved surface of at least a part of the part of the fitting ledge 314 whose outer diameter decreases. As a result, even if the fitting portion 314 is formed on the other side of the sewer pipe connection body 310, the other side of the sewer pipe connection body 310 can be easily connected to the sewer pipe 6 embedded in the wall 4, etc., and the sewer pipe ( The other side of the sewer pipe connection body 310 connected to 6) may not be easily separated from the sewer pipe 6.

The fitting ledge 314 may be formed on the other side of the sewer pipe connection body 310 before the diameter reduction portion 313 in the direction of the other end of the sewer pipe connection body 310. That is, the insertion portion 314 may be connected to the diameter reduction portion 313. However, the portion of the other side of the sewer pipe connection body 310 where the fitting ledge 314 is formed is not particularly limited. For example, the sewer pipe connection body 310 may have a pipe shape. Additionally, the sewer pipe connection body 310 may be arranged horizontally. However, the shape or arrangement direction of the sewer pipe connection body 310 is not particularly limited.

Referring to FIGS. 3, 4, and 6, the water blocking member 320 may extend from the inner peripheral surface of the sewer pipe connection body 310 to block at least a portion of the flow space 311. In this case, the water blocking member 320 may be extended so that its upper end is placed lower than the upper end of the sewer pipe connection body 310 and above the upper end of the flow connection hole 201 of the support part 200. With this configuration, when the water discharged from the drain pipe 3 connected to the drain pipe connection part 100 flows to the sewer pipe 6 connected to the sewer pipe connection part 300, the flow guide space 112 of the drain pipe connection part 100 and The flow space 311 of the sewer pipe connection part 300 may be filled with water at a level equal to the height of the top of the water blocking member 320. In this state, if water continues to be discharged from the drain pipe 3, water may continue to be supplied to the flow guide space 112 of the drain pipe connection portion 100.

In addition, the water in the flow guide space 112 of the drain pipe connection part 100 flows into the flow space 311 through the flow connection hole 201 of the support part 200 and flows through the water blocking member 320 to the sewer pipe 6. It can be fluid. In this case, water may flow from the flow guide space 112 of the drain pipe connection part 100 to the flow space 311 through the flow connection hole 201 of the support part 200. However, the flow connection hole 201 of the support part 200 may be blocked by water filled in the flow guide space 112 and the flow space 311 of the drain pipe connection part 100. Therefore, it is possible to prevent odors such as odors flowing into the flow space 311 from the sewer pipe 6 from flowing into the drain pipe 3 connected to the drain pipe connection 100 through the flow connection hole 201 of the support portion 200. You can.

In addition, most foreign substances such as bugs that have entered the flow space 311 from the sewer pipe 6 may be in the water filled in the flow guide space 112 and the flow space 311 of the drain pipe connection 100. It is possible to prevent foreign substances such as insects from entering the drain pipe (3) connected to the drain pipe connection portion (100). Foreign matter such as bugs in the water filled in the flow guide space 112 and flow space 311 of the drain pipe connection part 100 is separated from the sewer pipe connection part 300 from the sewer pipe 6 and flows into the flow guide space 112. The water filled in the space 311 can be removed from the flow guide space 112 and the flow space 311 by discarding it to the outside through the sewer pipe connection part 300.

Meanwhile, the water blocking member 320 may extend upward at a predetermined angle in the direction in which the sewer pipe connection body 310 extends. With this configuration, even if the water blocking member 320 blocks at least a portion of the flow space 311 of the sewer pipe connection body 310, water will flow smoothly from the flow space 311 to the sewer pipe 6. You can. For example, the water blocking member 320 may extend upward at an angle of 30 degrees in the direction in which the sewer pipe connection body 310 extends. However, the angle at which the water blocking member 320 extends obliquely upward in the direction in which the sewer pipe connection body 310 extends is not particularly limited. Additionally, the water blocking member 320 may be a curved plate at least partially convex in the direction of water flow. Even with this configuration, even if the water blocking member 320 blocks at least a portion of the flow space 311 of the sewer pipe connection body 310, water will not flow smoothly from the flow space 311 to the sewer pipe 6. You can.

In this state, if water continues to be discharged from the drain pipe 3, the water in the flow guide space 112 of the drain pipe connection part 100 flows into the flow space 311 through the flow connection hole 201 of the support part 200. It flows and can flow beyond the water blocking member 320 and into the sewer pipe (6). In this case, water may flow from the flow guide space 112 of the drain pipe connection part 100 to the flow space 311 of the sewer pipe connection part 300 through the flow connection hole 201 of the support part 200. However, the flow connection hole 201 of the support part 200 may be blocked by water filled in the flow guide space 112 of the drain pipe connection part 100 and the flow space 311 of the sewer pipe connection part 300. Therefore, odors such as bad odors flowing into the flow space 311 of the sewer pipe connection part 300 from the sewer pipe 6 are transmitted to the drain pipe 3 connected to the drain pipe connection part 100 through the flow connection hole 201 of the support part 200. It can be prevented from entering.

In addition, foreign substances such as insects that have flowed into the flow space 311 of the sewer pipe connection part 300 from the sewer pipe 6 are almost always in the flow guide space 112 of the drain pipe connection part 100 and the flow space of the sewer pipe connection part 300. Since it may be in the water filled in (311), foreign substances such as bugs can be prevented from flowing into the drain pipe (3) connected to the drain pipe connection portion (100). Foreign substances such as bugs in the water filled in the flow guide space 112 of the drain pipe connection 100 and the flow space 311 of the sewer pipe connection 300 are separated from the sewer pipe connection 300 and the flow guide. The water filled in the flow space 311 of the space 112 and the sewer pipe connection part 300 can be removed from the flow guide space 112 and the flow space 311 by discarding it to the outside through the sewer pipe connection part 300.

Meanwhile, in a state in which the drain pipe 3 connected to the water-using device 2, such as a washbasin or sink, is separated from the drain pipe connection hole 111 of the drain pipe connection portion 100, the sewer pipe connection portion 300 is connected to the wall 4, etc. By separating it from the buried sewer pipe 6, the drain pipe connecting device 1 according to an embodiment of the present invention can be easily separated.
