In the above configuration, the top of the water collecting tank 100 is opened as shown in FIGS. 3 to 4B. The reason for opening the top is to combine a lid (not shown), so that the lid is It is preferable to be installed so as to be detachably coupled from the open top, and such a lid may use a porous lid that exhausts odors or a closed lid that does not exhaust odors.

In addition, a certain amount of wastewater is collected in the collection space 110 inside the collection tank 100, and at least one wastewater inlet pipe 200 is installed on the side of the collection tank 100. The inlet pipe joint 120 is formed to receive sewage and wastewater discharged from a plurality of places in the home or various buildings and collect a certain amount.

In addition, on the other side of the water collection tank 100, a waste water discharge pipe coupling 130 is formed in which a waste water drainage pipe 300 is installed, so that the waste water collected in the water collection tank 100 is disposed of in the waste water discharge pipe coupling ( 130) through the sewage and wastewater drainage pipe 300.

However, the wastewater discharge pipe coupler 130 where the wastewater drain pipe 300 is installed is at a position lower than the position of the wastewater inlet pipe coupler 120 where the wastewater inlet pipe 200 is installed. It is formed so that the waste water collected in the water collection tank 100 is drained through the waste water drain pipe 300 without flowing back into the waste water inlet pipe 200.

In addition, in the wastewater inlet pipe 200 of the present invention, a joint part A is formed located outside the water collecting tank 100 and the angle is adjusted. The reason for forming the angle-adjusted joint part A is that home or When a straight line cannot be maintained between the direction of the wastewater inlet pipe 200 and the direction of the wastewater pipe 400 that transports the wastewater discharged from the building, the angle is adjusted with the joint part A so that the wastewater inlet pipe ( 200) and the waste water pipe 400 can be easily connected and installed.

Conventionally, when the water collection tank 100 is buried in a target place and connected to the wastewater pipe 400 for transporting wastewater generated in homes or buildings, the wastewater pipe 400 and the wastewater inlet pipe ( 200) is not maintained in a straight line, the buried water collection tank 100 is excavated from the landfill site, and the dug water collection channel 100 is re-buried to maintain a straight line with the wastewater inlet pipe 200, or The wastewater pipe 400 must be bent, or a bent pipe must be installed to connect the wastewater pipe 400 to the wastewater pipe 400 and the wastewater inlet pipe 200. There was a problem that the work time was delayed.

In addition, when replacing the previously installed wastewater inlet with the wastewater inlet of the present invention, the water collection tank 100 is buried so that the wastewater pipe 400 and the wastewater inlet pipe 200 maintain a straight line. I had a hard time doing it.

Therefore, the present invention is to form a joint portion (A) in the waste water inlet pipe 200 to solve the above conventional problems, and the joint portion (A) is formed to be located outside the water collecting tank (100), so that the waste water pipe ( 400) and the waste water inlet pipe 200 can be easily connected and installed without maintaining a straight line.

In addition, the waste water outlet 242 formed in the waste water inlet pipe 200 discharges the waste water to the collecting tank 100, and the waste water outlet 242 discharges the waste water. A damper 260 whose degree of opening and closing is determined according to the amount is installed so that the degree of opening and closing of the damper 260 varies according to the discharge amount of sewage and wastewater, that is, the water pressure.

As described above, a tray 244 is formed at the lower end of the waste water outlet 242 to which the damper 260 is installed. The reason for forming the tray 244 is,

First, the lower portion of the damper 260 is submerged in the wastewater accommodated in the tray 244 to block the space between the wastewater discharge port 242 and the tray 244, thereby reducing odors generated in the water collection tank 100. Prevent backflow into the wastewater outlet (242),

Second, the precipitate present in the waste water is deposited on the floor and the waste water overflowing the tray 244 is collected in the water collecting tank 100, thereby minimizing the deposition of the sediment in the water collecting tank 100 and at the same time. This is to prevent the sediment from being deposited on the wastewater drain pipe 300 to prevent clogging of the wastewater drain pipe 300 and to ensure smooth drainage of the wastewater.

The sewage and wastewater inlet of the present invention described above will be described in more detail with an example as follows.

- under -

As shown in FIG. 5, in the wastewater inlet pipe 200 of the present invention, a first sphere 211 for forming the joint portion A is formed at the front and the wastewater is disposed at the rear of the first sphere. The outer inlet pipe 210 having a coupling portion 212 coupled to the pipe 400 is formed, and a second sphere 221 at the rear so as to be rotatably coupled with the first sphere to form the joint portion A An inner inlet pipe 220 formed with a connection part 222 formed in front of the second sphere and a sphere on either side of the first and second spheres to prevent leakage of wastewater to the joint portion A. The installed sealing member 230 and the fastening part 241 installed to be detachably coupled with the connection part 222 are formed at the rear end, and a waste water outlet 242 through which waste water is discharged is formed in front of the fastening part. It is composed of a waste water discharge pipe 240 formed by forming a tray 244 at the bottom of the waste water discharge port.

In the above configuration, the outer inlet pipe 210 and the inner inlet pipe 220 are formed separately, because the first and second spheres 211 and 221 are coupled to each other and then rotated and the angle is adjusted (A). ) to form

In addition, a sealing member 230 is installed on one of the spheres on either side of the first and second spheres 211 and 221. The reason for installing the sealing member 230 is that sewage and wastewater leaks at the joint portion A. to prevent becoming

In the installation of the sealing member 230, the sealing member seating groove 232 is formed on one of the first and second spheres 211 and 221, and the sealing member 230 is formed in the sealing member seating groove 232. ) At least one O-ring 231 is installed to prevent leakage of wastewater between the first and second spheres 211 and 221.

The O-rings 231 are rubber, silicone, or resin O-rings having elasticity, and are preferably installed in two lines along the circumferential direction of the sphere.

In addition, the reason why the damper 260 is installed in the waste water outlet 242 and the tray 244 is formed in the configuration of the waste water discharge pipe 240 is that the tray 244 A part of the lower part of the damper 260 is submerged in the wastewater received in the wastewater outlet 242 and the tray 244 to block the space between the wastewater outlet 242 and the tray 244 so that the odor generated in the collecting tank 100 is directed to the wastewater outlet 242. By preventing backflow, and by allowing the sediment present in the wastewater to settle on the bottom and the wastewater overflowing the tray 244 to be collected in the water collecting tank 100, the deposition of sediment in the water collecting tank 100 is minimized. In addition, it is to prevent the clogging of the wastewater drainage pipe 300 by preventing sediment from being deposited on the wastewater drainage pipe 300, as well as to ensure smooth drainage of the wastewater.

In addition, a female screw 222a is formed in the connection part 222, and a male screw 241a screwed with the female screw 222a is formed at the rear of the wastewater discharge pipe 240, so that the inner inlet pipe 220 and the When a lot of sediment is deposited on the tray 244 by separating and combining the wastewater discharge pipe 240 as necessary, the wastewater discharge pipe 240 is separated from the inner inlet pipe 220 to remove the sediment, and then back into the inner inlet pipe. (220) and screwed together, and if the wastewater discharge pipe 240 is old, damaged or damaged, it can be replaced with a new wastewater discharge pipe 240.

In addition, it is preferable to maintain airtightness by interposing an O-ring between the connecting portion 222 and the fastening portion 241 to which the female screw 222a and the male screw 241a are screwed together.

The sewage and wastewater discharge pipe 240 can be separated and coupled to the rear part where the fastening part 241 is formed and the front part where the tray 244 where the damper 260 is installed is formed. keep this

The damper 260 of the present invention is preferably formed of any one of resin, silicone, and rubber having soft elasticity, because the wastewater discharged from the wastewater discharge port 242 This is to make the opening and closing degree vary according to the amount, that is, the water pressure, and at the same time, when the wastewater is not discharged from the wastewater outlet 242, the damper 260 tightly blocks the wastewater outlet 242.

The wastewater outlet 242 is formed obliquely from the top to the bottom because the wastewater easily flows down to the tray 244 and at the same time in the predetermined inner diameter of the wastewater discharge pipe 240 This is to secure the maximum size of the wastewater outlet 242 and to maintain airtightness between the damper 260 and the wastewater outlet 242 by the load of the damper 260.

As described above, in order to maintain airtightness between the damper 260 and the wastewater outlet 242, the outer edge of the back surface of the damper 260 is supported inside the wastewater outlet 242 where the damper 260 is installed. By forming a step 242a that supports the damper 260, the outer edge of the back side of the damper 260 is in close contact with the step 242a, so that airtightness is maintained between the damper 260 and the wastewater discharge port 242, and at the same time The step 242a stably supports and supports the damper 260 .

In addition, the damper 260 is formed to have a length whose lower end is positioned below the upper end of the tray 244 so that a lower part of the damper 260 is submerged in the waste water accommodated in the tray 244, so that the By blocking and sealing the wastewater outlet between the wastewater outlet 242 and the tray 244, odors or harmful gases generated in the water collecting tank 100 are prevented from entering the room through the wastewater pipe 400. .

Therefore, the length of the damper 260 is formed such that the lower end has a length located below the upper end of the tray 244, so that a part of the lower part of the damper 260 is submerged in the wastewater received in the tray 244. Preferably, do.

In addition, the lower part of the damper 260 is formed with an operating member fixture 262 in which an end of an operating member 263 capable of lifting or lowering the damper is installed. The operating member fixture 262 and the operating member The reason for forming 263 is that when the wastewater outlet 242 is blocked by foreign substances or the wastewater discharge is not easily performed, the damper 260 is lifted through the operating member 263 to This is to enable the remodeling of the sewage and wastewater outlet 242.

In addition, on the bottom surface of the collecting tank 100 of the present invention, a support 140 supporting and supporting the lower portion of the tray 244 is formed to protrude from the bottom surface of the collecting tank 100, and the support 140 The reason for this formation is that when the wastewater is accommodated in the tray 244 and the weight of the tray 244 becomes heavy, the wastewater discharge pipe 240 is deformed or damaged, so the wastewater discharge pipe 240 This is to prevent deformation or damage.

In addition, a key 254 is formed to protrude from the waste water discharge pipe 240 in which the waste water outlet 242 is formed, and one side of the sewage and waste water inlet fitting 120 formed in the water collecting tank 100 has the above The keyway 150 to which the key 254 is coupled is formed. The reason for forming the key 254 and the keyway 150 is to separate or combine the inner inlet pipe 220 and the wastewater discharge pipe 240. In order to mutually couple the female screw 222a formed on the connection part 222 of the inner inlet pipe 220 and the male screw 241a formed on the fastening part 241 of the wastewater discharge pipe 240, the inner inlet pipe 220 This is to prevent the sewage and wastewater discharge pipe 240 from interlocking, that is, rotating together.

Also, the key 254 is preferably formed on the fixing member 250 described above.

In addition, when the outer inlet pipe 210 is rotated to connect and install the waste water pipe 400 to the coupling part 212 of the outer inlet pipe 210, the inner inlet pipe 220 and the waste water discharge pipe 240 ) is rotated together, the position of the tray 244 is changed, so even if the outer inlet pipe 210 is rotated to connect and install the wastewater pipe 400, the key 254 coupled to the keyway 150 As a result, the wastewater discharge pipe 240 is not rotated so that the tray 244 is stably positioned at a desired position.

In addition, in the present invention, a porous basket (not shown) in which foreign substances are filtered is installed in the tray 244 to be detachable from the tray 244, so that when foreign substances are present in the basket, the basket is separated from the tray 244 and foreign substances If foreign substances are removed by combining the basket with the tray 244 again after removing the foreign substances, it is possible to prevent the wastewater drain pipe 300 from being clogged because no foreign substances exist in the water collecting tank 100.

In addition, the damper 260 is installed to be detachably coupled from the wastewater inlet pipe 200, and the odor of the collecting tank 100 is removed from the wastewater discharge pipe 240 and the wastewater inlet pipe 200 Through this, backflow into the room can be prevented, and when sediment is deposited on the tray 244, when the tray 244 is deformed or damaged, or when the damper 260 is worn out, it can be replaced.

In the damper 260 as described above, the coupler 261 is formed to protrude from the upper central tip, and the coupler 261 is seated in the upper central wastewater discharge pipe 240 of the sewage and wastewater outlet 242 A coupler seating groove 243 to be coupled is formed so that the coupler 261 is seated and coupled to the coupler seating groove 243.

As described above, when the coupler 261 is seated and coupled to the coupler seating groove 243, the coupled coupler 261 is fixed via the fixing member 250 so that it does not escape from the coupler seating groove 243. , The fixing member 250 is installed to be coupled and separated from the wastewater discharge pipe 240.

The fixing member 250 installed to be coupled separately from the wastewater discharge pipe 240 is installed outside the wastewater discharge pipe 240 at the portion where the coupler 261 is seated and coupled, and its shape is coupled It is preferable that the ball seating groove 243 is formed to match the external shape of the waste water discharge pipe 240 formed thereon.

The fixing member 250 as described above is formed in a semicircular shape when the wastewater discharge pipe 240 is in the form of a cylindrical pipe, and when the wastewater discharge pipe 240 is a polygonal shape, a polygonal shape corresponding to an upper portion of the polygonal shape. It is preferable to form The reason is to stably fix the coupler 261.

In addition, a coupling groove 251 is formed along the longitudinal direction of the fixing member 250 in the sewage and wastewater discharge pipe 240 to which the fixing member 250 is coupled, and in the longitudinal direction of the inner circumferential surface of the fixing member 250. A fitting 253 fitted into the coupling groove 251 is formed and the fitting 253 is closely fitted into the coupling groove 251, so that the coupler 261 is fitted into the coupling groove 243 It is firmly bonded and fixed to.

Meanwhile, when the damper 260 is to be separated, the fixing member 250 may be separated from the wastewater discharge pipe 240 and the coupler 261 may be separated from the coupler seating groove 243.

And, after the fixing member 250 is installed on the wastewater discharge pipe 240, no chin is generated between the fixing member 250 and the wastewater discharge pipe 240, and the same surface as the wastewater discharge pipe 240 is formed.
