The present invention relates to a drain trap, and more particularly, a connection socket for connecting a wastewater discharge pipe of a sewage generating device (eg, a wash basin, a washing machine, etc.) to a floor drainage pipe as a drainage trap for preventing odors from flowing back from the floor drainage pipe. The present invention relates to a drainage trap for connecting socket, which can realize the function of.

In general, the bottom of the bathroom is a drainage piping system for draining the sewage of the floor to the floor drain pipe without the backflow of odor and drainage of sewage, such as wash basin to the floor drain pipe.

5 is a schematic diagram of a conventional conventional bathroom drainage pipe.

As shown, the conventional bathroom drain pipe installation is installed on the bathroom floor, as a pipe part connected to the floor drain pipe 101, T-shaped socket 110 for connecting the drain trap 102 to the floor drain pipe 101 , The elbow 120 is connected to the T-shaped socket 110 is connected to the sewage discharge pipe 104 of the sink 103 is a sewage generating mechanism, and the connector 130 connecting the T-shaped socket 110 and the elbow 120 ) Is used.

As such, the conventional bathroom drainage piping facility in which the drain trap and the sink are installed requires a large number of parts, such as a T-shaped socket 110, an elbow 120, and a connecting pipe 130, and thus requires a lot of material costs. Of course, there is a problem that construction is also cumbersome.

In addition, in the conventional bathroom drainage pipe facility, when connecting the sewage discharge pipe 104 of the wash basin 103 is coated with a silicone or the like on the connection portion, but the use of the gap (104a) occurs when the odor is generated In many cases, there is a problem in that a trap 104b, such as an S trap or a P trap, must be separately formed in the sewage discharge pipe 104 of the sink 103 despite the existence of the drain trap 102.

In addition, in the case of the veranda where the washing machine is installed as a sewage generating mechanism, the water of the floor is drained through the drain trap so that the odor is not flowed back, but the water discharged from the washing machine may be drained directly through the bottom drain pipe without trap. Odor flows back from the bottom drain pipe, and in some cases, pests such as mosquitoes are introduced into the room.

An object of the present invention is to solve the problems related to the drain pipe of the floor as described above, connecting the sewage discharge pipe such as wash basin or washing machine with the floor drain pipe with the function of the drain trap to prevent the backflow of odor from the floor drain pipe By providing a drainage trap for the connecting socket that also functions as a connecting socket, it is intended to improve the convenience of construction and reduce the construction cost by simplifying the attachment of the floor drainage piping facility.

Another object of the present invention is that the drain trap acts not only as a trap for bottom sewage but also as a trap for sewage from the sewage discharge pipe of the sewage generating device, thereby eliminating the need to install a separate trap in the sewage generating device. The purpose of the present invention is to provide a drainage trap for connecting sockets, which can more effectively block backflow of odor and influx of pests.

According to the present invention there is provided a connecting socket combined drain trap.

The connecting socket combined drain trap according to the present invention includes a trap part, a discharge pipe connector, and a drain pipe connector.

The trap part may include a first chamber having an inlet through which bottom sewage flows, a second chamber having an outlet of sewage at a predetermined height, and a height of the outlet at a boundary between the first chamber and the second chamber. A odor blocking wall extending downward from the top so that a water passage is formed at a lower side of the lower position, and filthy water introduced into the first chamber in the state where the odor blocking wall is occupied to the height of the outlet so that the odor blocking wall is immersed in the sewage Is drained to the outlet of the second chamber, but odor is prevented from flowing back from the second chamber to the first chamber by the odor blocking wall.

The discharge pipe connector is formed on one side of the first chamber and is connected to the discharge pipe connecting socket for connecting the wastewater discharge pipe of the sewage generating mechanism, and the wastewater of the sewage discharge pipe is introduced into the first chamber.

The drain pipe connector is formed at the outlet of the second chamber and is connected to the drain pipe connecting socket for connecting the bottom drain pipe, and the waste water from the outlet is drained to the bottom drain pipe.

Preferably, the opening and closing wing is formed with a reservoir for providing buoyancy.

Preferably, the apparatus further includes a removable filter plate for removing foreign matter from the sewage introduced into the first chamber through the discharge pipe connector.

The connecting socket combined drain trap according to the present invention also functions as a connecting socket connecting the sewage discharge pipe such as a wash basin or a washing machine to the floor drain pipe together with the function of the drain trap preventing odors from flowing backward from the floor drain pipe. By simplifying the parts of the facility, the convenience of construction is improved and the cost of construction is reduced.

In addition, since the drain trap according to the present invention acts not only as a trap for sewage at the bottom but also as a trap for sewage from the sewage discharge pipe of the sewage generating device, a separate trap is provided to the sewage discharge pipe of the sewage generating device such as a sink or a washing machine. It can effectively prevent the introduction of odors or pests from the bottom drain pipe without forming a.

Hereinafter, with reference to the accompanying drawings will be described in more detail the combined drain trap according to the invention. The following embodiments are merely illustrative of the drain trap according to the invention, it is not intended to limit the scope of the invention.

As shown, the connection socket combined drain trap 1 according to the present invention is a bathroom or porch in which various sewage generating mechanisms 4 are used, such as a sink 4a, a washing machine (not shown), and a bathtub (not shown). It is installed on the bottom (2) of the back, drains the sewage (3) flowing through the bottom (2) to the bottom drain pipe (7) without the backflow of odor and at the same time the sewage (3) of the sewage generating mechanism (4) to the bottom drain pipe ( It is a drain trap for draining to 7).

As shown, the drain trap 1 of the present invention, the trap portion 10, the discharge pipe connector 20 and the drain pipe connector (30).

Here, the 'discharge pipe' means a sewage discharge pipe 5 for discharging sewage from various sewage generating mechanisms 4, such as a sink 4a or a washing machine (not shown), and the 'drain pipe' refers to the drain trap 1 of the present invention. Means the bottom drain pipe (7) for draining the drain through the drain pipe.

First, the trap part 10 includes the first chamber 11, the second chamber 12, and the odor blocking wall 13.

The first chamber 11 has an inlet 11a through which the sewage 3 flows in at the height of the bottom 2 so that the upper part of the first chamber 11 in which the sewage 3 flowing through the floor 2 of the bathroom or the veranda is opened. to be.

The second chamber 12 is positioned side by side with the first chamber 11 in the horizontal direction, and an outlet 12a through which the sewage 3 is discharged is formed above the predetermined height, and has the same water level as the first chamber 11. The sewage (3) is introduced into the chamber.

The odor blocking wall 13 is a wall forming a boundary between the first chamber 11 and the second chamber 12, and does not completely isolate the first chamber 11 and the second chamber 12, but the exit ( A water passage 13a is formed to extend from the top to the position lower than the height of 12a so that the sewage 3 flows from the first chamber 11 to the second chamber 12.

Thus, the sewage (3) flowing into the inlet (11a) of the trap portion 10 from the bottom (2) is temporarily stored in the first chamber 11 and the second chamber 12, wherein the water level of the sewage (3) While maintaining the same water level as the height of the outlet 12a, the lower end of the odor blocking wall 13 is immersed in the sewage 3, whereby the odor of the bottom drain pipe 7 is discharged from the second chamber 12 to the first chamber ( 11) to prevent backflow, and as a result, the odor of the floor drain pipe 7 is blocked from entering the room such as a bathroom or a veranda.

That is, when the sewage (3) of the bottom (2) flows into the trap unit 10, the sewage to the height of the outlet (12a) in the first chamber 11 and the second chamber 12 connected to the water passage (13a) (3) remains cold, and in this state, the odor blocking wall 13 is locked to the sewage (3), so that the sewage (3) of the bottom (2) when the sewage (3) continuously flows in Although discharged through the outlet 12a via the first chamber 11, the water passage 13a, and the second chamber 12, the odor is blocked by the odor blocking wall 13 and is removed from the second chamber 12. It will not be able to flow back into the chamber 11.

Preferably, a jaw 14 is formed around the upper end of the first chamber 11 of the trap part 10 to filter foreign matter such as hair included in the sewage 3 and / or the grill 15. Can be installed over 16).

The discharge pipe connector 20 is formed in the first chamber 11 of the trap unit 10, and is a structure for connecting the sewage discharge pipe 5 of the sewage generating mechanism 4, such as a washbasin or a washing machine.

It is also possible to connect the sewage discharge pipe 5 directly to the discharge pipe connector 20, but the sewage generating mechanism 4 has a wide variety of specifications of the sewage discharge pipe 5 depending on the type thereof, so that the sewage discharge pipe 5 is actually discharged. Connecting directly to the connector 20 is very poor workability, in the present invention, without connecting the sewage discharge pipe 5 directly to the discharge pipe connector 20, first connect the discharge pipe connecting socket (6) to the discharge pipe connector (20) And it is based on connecting the wastewater discharge pipe (5) to the discharge pipe connection socket (6). At this time, it is also possible to connect the sewage discharge pipes 5 of two sewage generating mechanisms 4 (eg, a sink and a bath tub) together using a T-shaped socket as the discharge pipe connection socket 6.

In marketing the drain trap according to the present invention, it is preferable to provide the discharge pipe connection socket 6 and the drain pipe connection socket 8 to be described later together with the trap part 10 as a set.

The drain pipe connector 30 is formed at the outlet 12a of the second chamber 12 and connects the bottom drain pipe 7 to allow the wastewater from the outlet 12a to be drained to the bottom drain pipe 7. .

It is possible to directly connect the bottom drain pipe 7 to the drain pipe connector 30, but since the pipe shape and position of the bottom drain pipe 7 are very diverse, the floor drain pipe 7 is directly connected to the drain pipe connector 30 in reality. Since the workability is lowered, without connecting the bottom drain pipe (7) directly to the drain pipe connector (30) to connect the drain pipe connection socket (8) to the drain pipe connector (30) and the bottom drain pipe (7) to the drain pipe connection socket (8) It is based on connecting.

In the illustrated embodiment, in partitioning the second chamber 12 in which the sewage 3 is accommodated, a part of the wall 8a of the drain pipe connecting socket 8 is a wall partitioning a part of the second chamber 12. An example is shown that is intended to be used, but is not limited to such.

According to the drain trap 1 according to the present invention described above, the sewage of the bottom flows from the first chamber 11 to the second chamber 12 through the inlet (11a) while trapping like a conventional floor drain trap It works.

Then, for example, when the sewage discharge pipe 5 of the wash basin 4a is connected to the discharge pipe connector 20 via the discharge pipe connecting socket 6, the sewage from the wash basin 4a passes through the trap part 10. Through the drain pipe connection socket (8) flows out to the bottom drain pipe (7), at this time, the odor from the bottom drain pipe (7) by the action of the trap portion 10 of course does not flow into the room through the inlet (11a) It does not flow into the wash basin 4a.

Further, in the waste trap 1 of the present invention, since the trap portion 10 also acts as a trap of the wash basin 4a in discharging the waste water of the wash basin 4a, the waste water discharge pipe of the wash basin 4a as in the prior art. It is possible to prevent the backflow of odor without forming an S trap or P trap separately in (5). Therefore, a straight pipe without a trap may be used as the wastewater discharge pipe 5 of the wash basin 4a, thereby contributing to cost reduction. .

In addition, even if a gap occurs in the connection portion between the discharge pipe connecting socket 6 and the sewage discharge pipe 5, unlike the prior art, since the odor from the bottom drain pipe 7 is blocked by the trap part 10, the gap is formed. Odor does not leak even if it occurs.

In addition, when the drain trap of the present invention is installed on the porch using a washing machine (not shown), when the sewage discharge pipe 5 of the washing machine is connected to the discharge pipe connector 20 through the discharge pipe connecting socket 6, from the washing machine Of sewage flows into the bottom drain pipe 7 through the drain pipe connecting socket 8 via the trap part 10, and at this time, the odor does not flow back from the bottom drain pipe 7 by the action of the trap part 10. do.

Therefore, in the case of the conventional veranda drain piping facility, the wastewater of the washing machine is discharged to the drain pipe as it is without a trap, but in some cases, it is impossible to prevent odors from flowing back from the drain pipe and prevent pests from entering the room. When used in connection with the sewage discharge pipe (5), it is possible to completely block backflow of odor and influx of pests.

Since the drain trap 1 of the present invention has a structure for accommodating not only the sewage of the bottom but also the sewage of other sewage generating mechanisms 4 such as a wash basin or a washing machine, If the amount of the sewage (3) introduced into the first chamber 11 is excessive, the phenomenon that the sewage is not discharged to the outlet (12a) may flow back to the inlet (11a).

Preferably, the drain trap 1 of the present invention may further include a removable backflow blocker 40 to prevent backflow of sewage.

The reverse flow blocking device 40 applied to the present invention is not particularly limited as long as it can block the flow of wastewater from the discharge pipe connector 20 to the inlet 11a without flowing to the outlet 12a. It may be configured to include a partition 41, the water passage 42 and the opening and closing wing 43 and the air cylinder 44.

The partition wall 41 is a wall that isolates a path through which the sewage (3) flowing from the discharge pipe connector (20) flows into the inlet (11a), and the water channel (42) is selectively used to allow the sewage (3) to pass through. 41) is a hole formed through.

Opening and closing wing 43 is rotatably installed in the water inlet port 42 is rotated to the upper side by the sewage (3) introduced from the discharge pipe connector 20 to close the water outlet (42), self-weight or inlet (11a) It rotates downward by the sewage (3) which flowed in from and opens the water flow port 42.

The opening and closing wing 43 is preferably formed so that the upper rotation is easily received by buoyancy when the opening and closing wing 43 is rotated to the upper side by the sewage introduced from the discharge pipe connector (20).

Demounting the backflow cutoff device 40 is for cleaning the trap part 10 and the like. As the detachable structure, the support 45 is formed at the corner of the partition wall 41 and the slit 17 is disposed at the trap part 10. It is possible to adopt a structure or the like to form the support 45 to be detachably coupled by fitting the support 45 to the slit 17.

According to such a reverse flow cutoff device 40, when excessive wastewater flows in from the wastewater discharge pipe 5 and the wastewater 3 tries to flow back toward the inlet 11a, the opening / closing wing 43 is moved upward by the wastewater 3. When the water flow port 42 is blocked while rotating, the sewage flows from the first chamber 11 to the second chamber 12 without backflow, and when the sewage at the bottom flows into the inlet 11a, the opening and closing wing 43 Since the opening and closing wing 43 is opened by the weight of the sewage and the load of the sewage, the water passage 42 is opened so that the sewage 3 naturally flows from the first chamber 11 to the second chamber 12.

In the drain trap 1 of the present invention, foreign matter such as hair contained in the sewage at the bottom may be filtered out through the above-described strainer 15 and / or the grill 16, but the sewage generating mechanism 4 such as a sink or a washing machine. It is not possible to filter foreign matter from the sewage flowing through the discharge pipe connector 20 from.

In order to remedy this, the drain trap 1 of the present invention preferably has a removable filter plate 50 for removing foreign matter from the sewage 3 flowing into the first chamber 11 from at least the discharge pipe connector 20. It includes more. Removing the filter plate 50 is to be able to clean the filtered foreign matter.

In the illustrated embodiment, the filter plate 50 is installed at the boundary between the first chamber 11 and the second chamber 12 adjacent to the backflow blocking device 40 and on the inner contour of the trap part 10. A mesh 52 is formed on the fitting edge 51 and a handle 53 is formed on the upper portion thereof so that the slits 18 formed on the trap part 10 can be detachably inserted.

In the illustrated embodiment, the application of the filter plate 50 may not only filter foreign matter from the sewage flowing through the discharge pipe connector 20, but also remove the foreign matter from the sewage introduced into the inlet 11a. Will be.
