The small manhole is connected to the kitchen, wash basin and bathroom as well as the drainage of the bathroom. If the drainage function does not have its own drainage function, the odor generated from the drainage of the toilet and the public sewer flows back to the kitchen, wash basin, and bathroom. Will cause.

In view of this point, drain traps for the purpose of discharging various waste water, such as kitchens, wash basins, bathrooms, etc., have various kinds of deodorization facilities installed at the inside or the top to prevent backflow of odor generated from the waste water. The blocking of odor is called bongsu so that water always accumulates in the drain trap so that odorous substances are blocked by bongsu and cannot enter the drip tray upstream.

Conventional small manhole is installed with the purpose as described above is to install a connection pipe between the height adjustment tube is installed the main body and the lid of the small manhole as shown in the accompanying drawings.

Since the size of the height control tube is typically made of Ø200mm ~ Ø500mm, there is a problem that only one connector can be used exclusively because the size of the connection tube is made identical according to the size of the height control tube.

For example, when the size of the pipe is larger or smaller than the connection of the small manhole when installing a small manhole using the diameter of the height adjusting pipe having a diameter of Ø300 mm, the diameter of the connector is Ø300 mm. It shall be used, or the diameter of the connection part of the body should be the same as that of the connector.

Therefore, when the size of the connector of the small manhole is different, there was a problem that one of the two can not be used, and furthermore, it may cause the impediment to the speed of work. As molds should be provided by size, it was also a cause of product cost increase.

On the other hand, if the diameter of the pipe connected to the inlet / outlet side is small or the center of the pipe connected to the center line of the inlet / outlet is difficult to connect, and furthermore, if the pipe connected is located above the center line of the outlet There was a problem that drainage is impossible.

In addition, the inlet is installed to prevent the backflow means, which is usually installed using a hinge to the plate-shaped stopper was rotated by water pressure or flow rate of the waste water was mainly used to the structure to fall by its own weight. However, the countercurrent prevention means has a problem that the foreign matter is accumulated at the tip of the opening of the countercurrent prevention means or when the foreign matter is located between the outlet and the stopper constituting the countercurrent prevention means loses its function.

The present invention has been made to solve the above problem is that the purpose of this is to change the structure of the connector of the small manhole can be used in a variety of sizes of the connection pipe in one small manhole can also be used in a variety of height adjustment pipe connected to it The present invention provides a compact manhole that provides a backflow prevention means for preventing odors while filtering foreign matter regardless of the flow rate and flow rate, and also easily connects pipes connected to the outlet and the inlet.

The object of the present invention is a small manhole is formed between the manhole body and the height adjustment pipe is installed in the lid while forming a connection groove to be fitted to the main body and the upper connection is made of a support tube is coupled to the height adjustment pipe is formed Absence; The holder is formed in the body is inserted into the inlet side of the small manhole is formed in the body and integrally formed with the body, the upper part of the connection fitting portion into which the pipe into which waste water is introduced into the holder is formed with a projection to be fitted into the coupling groove formed in the body of the manhole Absence; A switching part for changing the flow direction of incoming wastewater, wherein the switching part is integrally formed with a connection part inserted into the connection fitting part of the holder member; Odor prevention means consisting of a basket member formed in the upper end of the two sides of the switching unit is inserted into the upper groove and the upper portion is open and the inner space is formed in the inner side but the stepped portion is formed in the front end lower than the side wall height It is achieved by a multifunctional small manhole characterized in that the installation is made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The connecting member 300 is formed between the height control tube 200 is formed between the support groove 320 is formed in the connecting groove 310 is fitted to the main body and the height adjustment tube 200 is coupled to the upper portion is formed. And a coupling groove 412 formed in the body 411 inserted into the inlet side of the small manhole, and integrally formed with the body 411 to the upper portion of the connection fitting portion 413 into which a pipe into which waste water is introduced is inserted. The holder member 410 has a holder member 410 having a protrusion 414 fitted into the coupling groove 110 formed in the manhole body 100, and a switching part 422 for changing the flow direction of incoming wastewater. Fitting while being fitted to the connection fitting portion 413 A coupling groove into which the connection connecting member 420 having the protrusion 423 inserted into the upper portion 412 is integrally formed, and the protrusion 423 of the side surface of the switching unit 422 is fitted thereto. 431 is formed on the upper end of both sides and the top is open and the space portion 432 is formed on the inner side, but the stepped portion 433 is formed on the upper end of the odor prevention consisting of a basket member 430 formed to have a lower height than the side wall The means 400 is provided.

Meanwhile, as shown in FIGS. 5 to 6, one surface of the switch connecting member 420 constituting the basket member 430 is formed to be inclined, and the center line of the connection fitting portion 413 is the center of the body 411. It is preferable that it is formed to be located above.

In addition, the protrusion 512 is formed on the outside of the body 510 inserted into the inlet and the outlet of the manhole body, and is formed to penetrate the connection hole 513 through which the pipe is inserted. It is also possible to install and use the eccentric bushing 500 is formed to move and form the inclined surface 514 to the end of the connection hole (513).

The present invention having the structure as described above is the height adjustment tube by separating the connection member 300 when the size of the height adjustment tube 200 is installed on the upper portion of the main body as shown in Figure 9 attached to the upper or smaller ( After selecting the support tube 320 to be inserted 200, the connection groove 310 is inserted into the manhole body 100 to install the connection member 300, and if the height adjustment pipe 200 is small, the support tube 320 Use a connection member with a small diameter.

On the other hand, the pipe connected to the inlet side is fitted into the connecting fitting portion 413 of the holder member 410 flows through the switching unit 422 and the switching unit 422 is bent to form a flow direction of waste water Switched, and the inner ring 415 is formed on the inner side of the connection fitting portion 413 so that the fitting portion 413 of the holder member 410 is fitted to a certain depth when the pipe and the connecting portion 421 is fitted. And the flow through the connecting portion 421 and the switching unit 422 is bent is formed so that the flow direction of the waste water is switched.

In this case, when the front surface of the switching unit 422 is formed at right angles, the front surface of the switching unit 422 is inclined to form an inclined surface because it obstructs the wastewater introduced by the flow rate and flow rate, thereby changing the flow direction. Make it easy.

On the other hand, even if the hydraulic pressure of the waste water introduced by the protrusion 423 inserted into the coupling groove 412 hits the inclined surface of the switching unit 422, the hydraulic pressure acts, the connection fitting portion 413 of the holder member 410. In the switching connection member 420 is prevented from being separated.

The waste water dropped downward due to a change in the flow direction of the waste water is accommodated in the space portion 432 of the basket member 430 and is overflowed from the basket member 430 by the waste water continuously coming in. At this time, the step 433 is formed at the upper end of the front portion of the basket member 430, and the height of the front side is lower than that of the side wall, so that the waste water easily overflows from the basket member 430.

On the other hand, the basket member 430 can additionally obtain the effect of sedimenting foreign substances while reducing the flow rate and flow rate of the incoming wastewater, for example, when a lot of foreign matter accumulated in the basket member 430, the connection connecting member 420 When the separation is removed from the foreign matter contained in the space 432 and combined again, the projection 423 is fitted into the coupling groove 431 formed on the sidewall of the basket member 430 is easily combined.

As described above, the effect of filtering the foreign matter can be obtained, but the backflow of odor is prevented because the waste water remains in the basket member 430. Specifically, the discharge port of the switch connecting member 420 descends to the middle portion of the space portion 432 of the basket member 430, so that the discharge port of the switch connecting member 420 remains in the basket member 430 (waste water). Is blocked by).

Meanwhile, as shown in FIG. 9, the inlet / outlet forms a protruding protrusion 512 on the outside of the body 510 inserted into the main body 100 of the manhole, and connects a pipe 513 into which the pipe is fitted. The eccentric bushing 500 is formed to penetrate through the center 510 in one direction from the center of the body 510, and forms an inclined surface 514 toward the end of the connection hole 513.

The eccentric bushing 500 is an inclined surface when the inclined surface 514 is inserted to the lower side if the position of the pipe connected to the inlet is located above the center of the inlet of the manhole body 100, as shown in FIG. 8. 514 can be easily guided and drained into the manhole without falling, and if the position of the pipe connected to the inlet is located below the center of the inlet of the manhole body, the inclined surface 514 is inserted to the upper portion of the bushing and The manhole bottom is coincident to facilitate the inflow of wastewater.

When the eccentric bushing 500 is installed at the outlet, the inclined surface is installed at the upper portion and the inclined surface is inserted at the upper portion so that the bushing and the manhole bottom surface are coincided with each other so that the wastewater can be easily drained.

The reason why the protrusion 512 protruding from the outside of the body 510 is inserted into the coupling groove 110 provided in the manhole body 100 is to match the lowest point of the waste water with the lowest point of the bushing during inflow or discharge of the waste water. This is because there is an advantage to obtain convenience for.
