In addition, since the second part 114b connected to the first part 114a is connected to a portion of the main guide part 110 located approximately in the center of the flow space of the body 10, the overall flow of sewage flows through the body 10. When viewed in the radial direction, sewage can be concentrated approximately toward the center, allowing sewage to be discharged to the sewer more quickly.

In particular, the first portion 114a may include a recessed portion 114a1.

The recessed portion 114a may be configured to be recessed in the vertical direction at the bottom of the first part 114a.

According to this implementation configuration, the sewage to which the rotational force is applied to the sewage through the first part 114a can be discharged to the sewer side with reduced resistance when passing through the indentation portion 114a1, so that it can be discharged to the sewer side more quickly. of sewage discharge may occur.

Referring to FIGS. 1 and 3 to 5 , the body 10 may further include a first rotation guide unit 120 .

At this time, the main guide unit 110 may be located between different first rotation guide units 120 when viewed in the circumferential direction of the body 10. In addition, the curved portion 114 of the main guide portion 110 may also be located between different first rotation guide portions 120 when viewed in the circumferential direction of the body 10.

In this way, a greater rotational force can be applied to the sewage flowing within the flow space of the body 10 through the plurality of first rotation guide parts 120 formed along the inner peripheral surface (inner surface) of the body 10. Accordingly, sewage can be discharged more quickly to the sewer side.

In addition, since the main guide part 110, which can concentrate the overall flow of sewage toward the center, is formed between the first rotation guide parts 120 formed along the inner peripheral surface (inner surface) of the body 10, it is more convenient for sewage. It has the advantage of being able to provide rotational force in more diverse ways.

In particular, the first rotation guide unit 120 may be configured to be inclined in one direction when viewed from the circumferential direction of the body 10.

According to this implementation configuration, a rotational force can be applied in a certain direction to the sewage flowing within the flow space of the body 10, so there is an advantage in that sewage can be discharged more quickly and stably.

Referring to FIGS. 1, 3, and 6, the upper mounting portion 20 may further include a second rotation guide portion 220.

The second rotation guide unit 220 may be configured to guide the flow of sewage so that the sewage flows into the body 10. Additionally, at least one second rotation guide unit 220 may be provided along the upper mounting unit 20 . As an example, at least one second rotation guide part 220 may be provided along the upper surface of the upper mounting part 20.

As described above, the upper end of the body 10 may be seated on the stepped portion 210 formed on the radial center side of the upper mounting portion 20. At this time, the second rotation guide portion 220 may be formed on the upper surface of the upper mounting portion 20, extending in the radial direction from the step portion 210 to the outer end of the upper mounting portion 20.

In addition, the sewage flowing into the upper mounting portion 20 is guided by the second rotation guide portion 220 and flows into the flow space of the body 10 disposed on the radial center side of the upper mounting portion 20. may be introduced.

According to this implementation configuration, a rotational force can be applied to the sewage in advance before the sewage flows into the flow space of the body 10, so that the body 10 A stronger additional rotational force may be provided by the first rotation guide unit 120 within the frame. Accordingly, sewage can be discharged more quickly to the sewer side.

Meanwhile, the second rotation guide part 220 may include a bent part 222 and a vertical part 224.

The bent portion 222 may protrude from the upper mounting portion 20 and be bent. This bent portion 222 may be bent to protrude from the upper surface of the upper mounting portion 20 while forming a curved surface of a predetermined curvature.

According to this implementation configuration, a rotational force can be applied in a certain direction to the sewage that will flow into the flow space of the body 10, so there is an advantage in that sewage can be discharged more quickly and stably.

In addition, the sewage, which is primarily given a rotational force through the bent portion 222 on the upper surface of the upper mounting portion 20, can receive a secondary strong rotational force when it hits the vertical portion 224 configured to be tilted in one direction. Therefore, there is an advantage in that more diverse types of rotational force can be applied to the sewage flowing into the flow space of the body 10.

Referring to FIGS. 1, 3, and 7, the bottom sealing part 30 may further include a third rotation guide part 320.

The third rotation guide unit 320 may be configured to guide the flow of sewage flowing in from the body 10. In addition, at least one third rotation guide part 320 may be provided along the bottom sealing part 30. As an example, at least one bottom sealing part 30 may be provided along the upper surface of the bottom sealing part 30.

In particular, the third rotation guide part 320 may be configured to be inclined in one direction when viewed from the circumferential direction of the lower sealing part 30. In addition, the third rotation guide part 320 may be configured to have a greater curvature toward the upper side of the lower end sealing part 30.

According to this implementation configuration, a rotational force can be applied in a certain direction to the sewage to be discharged into the sewer through the flow space of the body 10, so there is an advantage in that sewage can be discharged more quickly and stably.

In addition, since the curvature of the third rotation guide part 320 is made larger at the upper side of the lower sealed part 30, which has a relatively smaller diameter than the lower side, the lower sealed part After generating a strong rotational force from the upper side of (30), the sewage can be induced to flow along the slope of the lower sealing part (30), thereby causing the sewage to be discharged toward the sewer with a greater rotational force generated.

Meanwhile, the tilting directions of the above-described first rotation guide unit 120, second rotation guide unit 220, and third rotation guide unit 320 may be the same.

According to this implementation configuration, in the process of discharging sewage toward the sewer through the upper mounting portion 20, the body 10, and the lower sealing portion 30, a rotational force can be applied to the sewage in a more constant direction.

Additionally, referring to FIGS. 3 and 4 , the second rotation guide unit 220 and the third rotation guide unit 320 may be provided in plural pieces.

At this time, as shown in FIGS. 3 and 4, the gap between the different second rotation guide parts 220 in the circumferential direction of the upper mounting portion 20 is different from the second rotation guide part 220 in the circumferential direction of the body 10. It may be configured to be larger than the spacing between the 1 rotation guide parts 120.

And, the distance between different first rotation guide parts 120 in the circumferential direction of the body 10 is the distance between different third rotation guide parts 320 in the circumferential direction of the lower sealing part 30. It can be configured to be larger.

That is, when viewed from the direction in which sewage is discharged toward the sewer through the upper mounting portion 20, the body 10, and the lower sealing portion 30, the sewage is discharged toward the sewer from the upper mounting portion 20 into which sewage flows. As it moves toward the lower sealing part 30, the gap between each rotation guide part 220, 120, and 320 may be configured to become smaller.

According to this implementation configuration, an increasingly larger rotational force can be applied to the sewage toward the sewer, which has the advantage of enabling more rapid and stable discharge of sewage.

That is, in the case where the load of sewage is applied to the lower sealing part 30 as shown in (a) of FIG. of As the pressing force according to the load becomes greater, the lower sealing part 30 can move downward along the main guide part 110 to open the lower end of the body 10. In this case, sewage can be quickly discharged into the sewer.

On the other hand, when the load of sewage applied to the lower sealing part 30 is released as shown in (b) of FIG. 9, the repulsive force acting between the first magnetic part 40 and the second magnetic part 50 As a result, the lower end sealing part 30 can be moved upward along the main guide part 110 to seal the lower end of the body 10. In this case, bad odors rising from the sewer can be blocked by sealing the bottom of the body 10.

According to this implementation configuration, when a load of sewage is applied without a separate complicated device or control configuration, the bottom seal 30 is moved to open the bottom of the body 10 so that the sewage can be quickly discharged into the sewer. However, when the load of sewage applied to the lower sealing part 30 is released, the lower sealing part 30 seals the lower part of the body 10 using magnetic force, thereby effectively blocking bad odors rising from the sewer.

Meanwhile, in the above-described embodiment, a configuration in which the bottom sealing portion 30 is moved by the repulsive force acting between the first magnetic portion 40 and the second magnetic portion 50 has been disclosed, but the configuration is not limited to this, and the first magnetic portion 40 and the second magnetic portion 50 are not limited thereto. Instead of the magnetic portion 40 and the second magnetic portion 50, an elastic member (e.g., spring, etc.) surrounding the outer peripheral surface of the main guide portion 110 is provided inside the lower sealing portion 30 to secure the lower sealing portion 30. ) When the load applied to the body is released, it is possible to configure the lower sealing part 30 to seal the lower end of the body 10 by the elastic restoring force of the elastic member.

The filter unit 70 may be disposed at the top of the upper holder 20. In addition, the filter unit 70 is formed with a plurality of holes H to filter foreign substances (eg, hair, etc.) contained in sewage.

Additionally, the filter unit 70 may be configured to guide sewage to flow into the upper mounting unit 20.

Specifically, the filter unit 70 may be configured to cover the entire upper surface of the upper mounting part 20. As an example, the cross-sectional shape of the filter unit 70 on the horizontal plane (XY plane) may be approximately square, but is not limited thereto.

At this time, the plurality of holes H of the filter unit 70 may each be formed to have the same predetermined size on the filter unit 70 and may be arranged to be spaced apart from each other at regular intervals. Additionally, the plurality of holes (H) may be configured to face the upper surface of the upper mounting portion 20 on which the second rotation guide portion 220 is formed in the vertical direction.

Accordingly, when sewage flows into the upper mounting part 20 through the filter unit 70, the sewage flowing rapidly from the outside flows into a plurality of holes (H) of the filter unit 70 having uniform sizes and uniform intervals. ) may flow uniformly into the upper mounting portion 20 while passing through.

According to the sewer trap 2 of this embodiment, the sewage that has passed through the filter unit 70 can be uniformly introduced into the upper holder 20, so that the second rotation guide part 220 of the upper holder 20 ), it is possible to guide sewage to flow into the flow space of the body 10 by more stably applying rotational force to the sewage.

Figure 11 is a diagram showing a sewer trap 3 according to another embodiment of the present invention.

Since the sewer trap 3 according to the present embodiment is similar to the sewer trap 1 according to the previous embodiment, redundant description of components that are substantially the same or similar to the previous embodiment will be omitted, and hereinafter, the previous embodiment will be described. Let's focus on the differences from the example.

Referring to FIG. 11, the sewer trap 3 may include a sealing portion 80.

This sealing portion 80 may be seated on the stepped portion 210 formed on the radial center side of the upper mounting portion 20. As an example, the sealing portion 80 may include a material such as silicon.

And, the sealing portion 80 may be configured to surround the outer periphery of the upper end of the body 10 seated on the step portion 210. At this time, the sealing portion 80 may be in close contact with the wall surface of the stepped portion 210 as shown in FIG. 11 .

According to this implementation configuration, the body 10 can be more closely coupled to the upper mounting portion 20, so that sewage can be more stably discharged through the upper mounting portion 20 and the body 10. there is.

In addition, according to this embodiment, the gap between the stepped portion 210 and the body 10 can be sealed through the sealing portion 80, so that sewage does not leak through the gap between the stepped portion 210 and the body 10. It is possible to prevent outflow and easily allow sewage flowing into the upper mounting portion 20 into the flow space within the body 10.

As described above, although the present invention has been described with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be understood by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalence of the patent claims to be described.

Meanwhile, in the present invention, terms indicating directions such as up, down, left, right, front, and back are used, but these terms are only for convenience of explanation and may vary depending on the location of the target object or the location of the observer. It is obvious to those skilled in the art that this can be done.
