1 to 5, the drain trap according to the present invention is a drain trap for discharging sewage to the sewer 40 through a cover 10 in which a plurality of drain holes 12 are drilled, buried in the bottom, The cover 10 is combined to pass the sewage, to form a water collecting space (25) where the collected waste water is collected first, and the water sealing trap 20 through which the sewage over the water collecting space 25 is discharged, and the water sealing trap Obtained in the upper portion of the 20, is installed between the water collecting space 25, the vortex-shaped spiral structure 32 is formed in a plurality of intervals at intervals in the height direction on any one of the inner surface or the outer surface Cap 30.

As shown, the drain trap according to the invention is buried in the bottom of a sewer, preferably a bathroom or a utility room, and connected to the sewer 40.

Drainage trap is largely composed of a water seal trap 20 and a water seal cap 30, the water seal trap 20 is covered by a cover (10).

The cover 10 is perforated with a plurality of drain holes 12, where sewage is drained through.

Sealing trap 20 is a structure that is sealed by the cover 10, the upper end of the control end 34 is projected, the lower portion is provided with a collecting space 25 made of a constant width and height .

The catchment space 25 is a place where the sewage passing through the cover 10 is accumulated, and the sewage is always accumulated by a certain amount, and the catchment space 25 is surrounded by the catchment part 22 and the drain part 24. It is an excitation structure, and in particular, the drainage part 24 is located inside the water collecting part 22 in the role of a drainage pipe, and the front end and the end thereof are connected after extending in the height direction.

The tip height of the drainage part 24 serves to limit the height of the catchment space 25, and forms the height and width of the catchment space 25 together with the outer wall of the catchment part 22.

For example, the sewage that has passed through the cover 10 is first accumulated in the collecting space 25 or discharged to the sewer 40 through the drainage part 24, and in such a structure, the sewage is discharged by the water hammer phenomenon. Does not play a role in preventing backflow of noise or odor.

Therefore, the above problem is solved by blocking the upper portion of the drain 24 and at the same time leaving a predetermined space to allow the sewage to pass through and preventing the odor from being discharged to the outside.

Sealing cap 30 for this to form a predetermined space while blocking the top, that is the tip of the drain 24 to allow the sewage to pass through.

In order to provide such a space, the sealing cap 30 is installed between the collecting spaces 25, and the spiral structure 32 is formed on the surface of the whirlpool and the outer circumferential surface thereof so as to protrude and form at intervals in the height direction. have.

At this time, the protruding spiral structure 32 is a structure fixed to one surface of the collecting portion 22 to the draining portion 24 forming the collecting space 25, due to this fixed structure back pressure and sewage of the drain 40 Can withstand pressure

On the other hand, the spiral structure 32 of the sealing cap 30 serves to induce vortices in the spiral, that is, whirlwind phenomenon when the sewage flows, the sewage passing through the spiral structure 32 is the drain hole 24 When drained through), the sewage is sucked up by the pressure difference based on the orifice principle, which increases the discharge rate.

In addition, since there is always a constant sewage in the collecting space 25, the odor flowing back through the sewer 40 does not pass.

6 is an exploded perspective view showing an exploded view of the drain trap according to another embodiment of the present invention, and FIG.

As shown in FIGS. 6 to 7, the collecting part 22 forming part of the collecting space 25 may further include a seating part 26.

Here, the seating portion 26 is buried in the bottom, and the separated water collecting portion 22 and the drainage portion 24 are seated on the seating portion 26 and inserted into the sewer 40.

That is, the seating portion 26 embedded in the bottom is a structure extending along the outer circumferential surfaces of the water collecting portion 22 and the draining portion 24 to guide the same, and the water collecting portion 22 and the draining portion 24 are seating portions ( It can be seen that the structure that can be inserted or taken out along 26).

In particular, a coupling key 22a protrudes from the outer circumferential surface of the collecting portion 22, and a coupling groove 26a is formed on the inner circumferential surface of the seating portion 26 that fixes the collecting portion 22, so that the collecting portion 22 is formed. ) And the mounting portion 26 can be firmly fixed, and the coupling key 22a and the coupling groove 26a may be selectively formed in the water collecting portion 22 and the mounting portion 26.

Therefore, due to the structure that can be easily separated as described above it is possible to take out the solid dirt and the like accumulated in the collecting space 25 to the outside.

Next, the wastewater discharge process of the drain trap and its effects will be described in detail.

First, the sewage is guided through the seating part 26 or the catching part 22 and flows into the water collecting space 25, and since the sewage or the dirt is accumulated in the water collecting space 25 in advance, It is pushed and overflowed to the drain part 24, and it drains.

At this time, since the spiral cap 32 is formed in the seal cap 30, the sewage is guided along the spiral structure 32 to form a vortex and quickly drained to the drain 24.

In addition, the vortex overflowing to the drainage part 24 generates an orifice phenomenon due to the pressure difference with the water collecting space 25, and thus, the drainage part 24 generates a powerful suction force, causing vortices and quickly sucking the drained sewage. To drain the sewage.

On the other hand, after drainage, a certain amount of wastewater remains at all times in the collecting space 25, and thus, the wastewater blocks the outside, ie, the atmosphere and the drain 40, so that the odor flowing back through the drain 40 is blocked.

In other words, as will be clear from the above description, the present invention allows the sewage to be discharged while causing vortices, and upon drainage, a strong drainage force can be induced by the orifice principle to achieve rapid drainage.

This invention can be implemented in other various forms, without deviating from the mind or main characteristics. For this reason, the above-described embodiments are merely examples in all respects and should not be interpreted limitedly. The scope of the present invention is shown by the scope of the claims, and is not limited by the specification text. Again, all variations and modifications belonging to the equivalent scope of the claims are within the scope of the present invention.

In the present invention, it goes without saying that various other modifications are possible. For example, it is not deviating from this invention that the cover 10-the mounting part 26 can also be deformed circularly as needed. Accordingly, all modifications existing within the spirit and scope of the present invention are included in the claims.

As described above in detail, according to the drain trap according to the present invention, the sewage drained by the spiral seal cap is guided in the shape of the vortex to discharge at a high flow rate, and the sewage trap of the integrated or separate type in which the waste water is discharged to the sewer. Combined with, the discharged sewage is sucked out by the orifice phenomenon is more rapid drainage, there is an effect to prevent the backflow of odor by blocking the atmosphere and the sewer by forming a constant collecting space.
