Description

Repulsive force open and close sewage trap {REPULSIVE FORCE OPEN AND CLOSE DRAIN TRAP}

The present invention relates to a repulsive open and close sewage trap, and more particularly, to a repulsive open and close sewage trap that is installed in a drainage device such as a sewage pipe and a drain pipe to drain water and prevent odor from flowing backward.

In general, the sewer of the sink and bathroom discharges domestic wastewater, but most of the domestic wastewater is water that is thrown away after washing or washing things and is contaminated with a lot of organic matter. As it flows into the room along the drain pipe, the room is contaminated with odor.

Conventionally, various methods have been attempted to prevent odors flowing into the room as described above.

Among them, a rubber cover has been used to close the drain in order to prevent the backflow of odors in the drains of household sinks.

However, because the cover is used for completely sealing the drain hole, the user must open the cover again in order to use the sink.There is a problem that odors flow back through the sink drain when the cover is opened. There is an inconvenience of having to open the door every time and cover it again after draining.

Another way to prevent odor was to form a part of the drain pipe into a drain trap (U-shaped, P-shaped, S-shaped, etc.) to allow water to accumulate at the bottom of the curved drain pipe to prevent odor from coming up along the drain pipe. In this case, if household wastewater or food waste is continuously accumulated in the bent portion of the drain pipe, the drain pipe becomes clogged, so it must be disassembled and cleaned from time to time, and it can be used where the drain pipe is exposed, such as sinks and washbasins. It is impossible to even use it where it becomes available.

Another way to prevent odor is by constructing a tube made of a thin material such as vinyl at the bottom of the drain pipe, so that when water flows in, the tube opens and drains, and after the drain is completed, the tube is in close contact to prevent the reverse flow of odor. However, this has the disadvantage of having to replace it at any time because the life of the tube is short and smooth adhesion for a long time cannot be expected.

Another way to prevent odor is to install a backflow prevention plate made of elastic material such as rubber in the drain pipe or the drain trap itself so that when water flows in, the backflow prevention plate bends and opens the passage of the drain pipe or the drain trap so that drainage can be done. Also, after drainage and completion, the backflow prevention plate returns to its original position by its own elasticity and closes the passage, thereby preventing the backflow of odor.

However, since the backflow prevention plate bends repeatedly every time water is drained, a crack is generated at the connection point between the non-bending portion and the bent portion of the backflow prevention plate fixed to the drain pipe or drain trap, causing the backflow prevention plate to return. A phenomenon of slowing down occurs, and in severe cases, there is a problem that the connection point is cut.

The present invention is installed in a drainage device 70 capable of draining water and is a self-opening type repulsive force-opening sewage trap 1 that can prevent backflow of odors, and the drainage body part 10, the drainage body part 10 A first magnet part 30 and a second magnet part controlling the backflow prevention part 20 to open and close the discharge port 122a of the backflow prevention part 20 to close the discharge port 122a of the drainage body part 10 It may contain (40).

In this case, the drainage device 70 may be a drainage hole installed in a bathroom, toilet, or a sink in the sink. Hereinafter, an example in which the drainage device 70 is applied to the sink in the sink will be described.

As illustrated in FIG. 1, the drain body portion 10 may include a spanning portion 11 and a body portion 12.

The straddling part 11 may be formed in a substantially disk shape, and may simultaneously span the inlet side positioned at the upper end of the drainage device 70 and the bottom surface of the washing container.

The hanging portion 11 has a central portion penetrating in the upper and lower directions, so that water that is discharged from the faucet when washing dishes or fruits and flows down the bottom of the sink can flow to the body portion 12. .

The body portion 12 is formed to have a smaller diameter than the spanning portion 11, and is integrally formed in the central portion of the spanning portion 11.

The body part 12 is inserted into the inside of the drainage device 70 and is formed in a cylindrical shape, and a passage 12a through which the water that has passed through the overhanging part 11 can flow toward the drain is formed therein. And, an outlet 122a is formed at the lower end of the passage 12a.

At this time, the backflow prevention part 20 to be described later opens and closes the outlet 122a of the body part 12 while rotating, and the operation is partially controlled by the repulsive force of the first magnet part 30 and the second magnet part 40. Bar, it is preferable that the body part 12 is formed in a form in which the operation of the backflow prevention part 20 can be performed ideally.

As an example, as shown in FIG. 1, the body part 12 may be formed in a form in which the length of the body part 12 gradually increases from one side to which the backflow prevention part 20 is coupled to the other side.

Accordingly, the outlet 122a is formed in an inclined shape to correspond to the shape of the body portion 12, and the backflow prevention portion 20 closes the outlet 122a in an inclined shape.

Additionally, the body portion 12 has a short portion 12c and a long portion 12d because it is formed in the above-described shape.

In addition, the short portion 12c is formed with a fixing means 12e on which a second magnetic portion 40, which will be described later, is installed.

The fixing means 12e is formed as a groove having an open bottom surface, and the second magnetic portion 40 may be inserted and fixed.

In addition, the short portion (12c) is formed with an extension portion 13 extending toward the passage (12a) and located above the fixing means (12e), and the backflow prevention portion (20) is rotated in the extension portion (13) An additional fixing means (13a) is formed to enable it.

The additional fixing means 13a may be a groove having an open bottom surface.

The connection relationship between the additional fixing means 13a and the backflow prevention unit 20 will be described in detail below.

The drainage body portion 10 described above is applied with a passage portion 14 capable of catching foreign substances such as food and passing water.

The passage portion 14 is seated on the upper inlet 121a side of the body portion 12, and a plurality of passage holes 14a for passing water through the passage 12a of the body portion 12 are fixed. Formed at intervals.

In this case, the passage part 14 may be configured to be simply seated on the upper surface of the body part 12 or be detachably coupled.

On the other hand, the backflow prevention part 20 is disposed on the discharge port 122a to block reverse flow of odors and sewage, and is formed in the same shape as the discharge port 122a, and the entire discharge port 122a can be closed. It is formed to have a size.

2, a buried groove 20a in which the first magnetic portion 30 is buried is formed on a surface facing the short portion 12c of the upper side of the backflow preventing portion 20. As shown in FIG.

In addition, as shown in FIG. 3, rotation shafts 21 are formed on both upper sides of the backflow prevention part 20 so as to rotate on the body part 12. As shown in FIG.

Specifically, a hinge bracket 15 is inserted and fixed on both sides of the additional fixing means 13a to support the backflow preventing portion 20 so as to be rotatably supported.

At this time, the hinge bracket 15 is inserted and fixed from the lower side of the additional fixing means 13a, and the upper side of the hinge bracket 15 is fixed by being inserted from the lower side of the additional fixing means 13a, as shown in FIG. 2, and the lower side may protrude to the lower part of the additional fixing means 13a. .

In addition, a through hole is formed in the hinge bracket 15 so that the rotation shaft 21 is inserted therethrough.

Accordingly, the backflow prevention part 20 can be rotated in the up and down directions on the hinge bracket 15 with respect to the rotation shaft 21.

At this time, when the discharge port 122a is closed, the backflow prevention part 20 maintains an inclined state by being supported at the lower end of the long part 12d of the body part 12, and when the discharge port 122a is opened, The upper side is supported by the short portion 12c.

The first magnet part 30 and the second magnet part 40 perform a function of returning to their original position when the backflow prevention part 20 rotates in the direction in which the discharge port 122a is opened by water. .

To this end, the first magnet part 30 and the second magnet part 40 are formed to have the same polarity so that repulsive force is generated with each other.

In addition, the first magnet part 30 may be rotated together with the backflow prevention part 20 to be rotated in a direction away from or close to the second magnet part 40.

In addition, the first magnet part 30 and the second magnet part 40 are disposed at positions that can face each other when the backflow prevention part 20 is rotated in the direction of opening the discharge port 122a.

Next, a description will be given of the operation and unique effects of the repulsive force opening and closing sewage trap 1 according to the present invention.

First, as shown in FIG. 2, when water does not pass through the passage 12a of the sea part, the second magnet part 40 is in a state in which the first magnet part 30 is being pushed by repulsive force, so the backflow prevention part (20) is in close contact with the bottom surface of the body portion 12 in an inclined form and maintains the state in which the discharge port 122a is closed.

And, when the drainage water is introduced into the passage (12a), as the backflow prevention unit (20) is rotated in a vertical form under the load of water and the discharge port (122a) is opened, the water is drained to the outside through the drainage device (70) It will be.

Then, when water is drained from the passage 12a, the second magnetic portion 40 pushes the first magnetic portion 30 with a repulsive force so that the backflow prevention portion 20 rotates back to the position where the outlet 122a is closed. .

For this reason, the backflow prevention part 20 closes the discharge port 122a again to prevent odors and wastewater from flowing backward.

That is, as described above, the repulsive force opening and closing sewage trap 1 according to the present invention is immediately drained from the passage 12a through the repulsive force generated between the first magnet part 30 and the second magnet part 40. It is possible to provide an advantage of increasing the efficiency of odor backflow blocking by quickly returning the backflow prevention unit 20 to its original position to close the outlet 122a.

Furthermore, the backflow prevention part 20 applied to the conventional sewage trap is made of a material having elasticity such as rubber, and is rotated downward by drainage while only one edge is fixed to the sewage trap body, and drainage is completed. Afterwards, it is rotated upwards by its own elastic force to prevent the backflow of odors and sewage as it is in its original position.Because it is repeatedly rotated up and down each time the drainage is drained, the fixed part of the backflow prevention unit 20 There was a problem that a crack was generated at the connection point of the rotating part and was cut. However, the repulsive force opening and closing sewage trap 1 according to the present invention flows backward through the repulsive force of the first magnet part 30 and the second magnet part 40. It is possible to close the outlet 122a by quickly returning the prevention part 20 to its original position, and it is possible to make the backflow prevention part 20 made of synthetic resin or plastic material that does not easily crack or separate, so it can be used semi-permanently. It can also provide advantages that can be used.

Next, another embodiment of the repulsive force opening/closing sewage trap according to the present invention will be described with reference to FIGS. 5 and 6.

5 is a perspective view showing an example in which a third magnet part and a gap maintaining part are applied to the repulsive force opening and closing sewage trap according to the present invention, and FIG. 6 is an example in which a third magnet part and a gap adjusting part are applied to the repulsive force opening and closing sewage trap according to the present invention. Is a cross-sectional view showing.

In this embodiment, a third magnet part 50 and a second magnet part 40 for limiting the open range of the backflow preventing part 20 while increasing the closing speed of the backflow preventing part 20 with respect to the discharge port 122a. It may further include a distance adjustment unit 60 for adjusting the distance between the and the third magnetic unit 50.

Specifically, a plurality of receiving grooves 12b are formed in the short portion 12c to be spaced apart from each other in the horizontal direction and facing the first magnet part 30.

And, the third magnet part 50 is accommodated in the receiving groove (12b).

At this time, the third magnet part 50 is formed to have the same polarity as the first magnet part 30, so that the first magnet part 30 may be pushed out by repulsive force.

In addition, the receiving groove 12b and the third magnetic portion 50 are formed in a dot shape. That is, the third magnet parts 50 are 1/3 to 1/10 of the first magnet part 30 or the second magnet part 40 so as not to push the first magnet part 30 with an excessive repulsive force. Can be formed in size.

Therefore, 3 to 10 receiving grooves 12b may be formed. And, the size of the receiving groove (12b) may be different depending on the number of applications.

In addition, the third magnet part 50 may be applied to all the receiving grooves 12b or may be applied in a smaller number than the receiving grooves 12b.

In other words, the strength of the repulsive force is different depending on the number of applications of the third magnet part 50, so that the closing speed and the open range of the backflow prevention part 20 are also different, so that the third magnet part 50 is accommodated in the receiving groove 12b. ) By selectively applying to any one or more of these, the closing speed and the open range of the backflow prevention unit 20 can be adjusted.

More specifically, when it is assumed that two receiving grooves 12b are applied, the third magnet part 50 is accommodated in only one receiving groove 12b, or the third magnet part is provided in both receiving grooves 12b. By accommodating 50, the closing speed and open range of the backflow prevention unit 20 may be adjusted.

In this way, when the third magnet part 50 is more selectively applied to generate a repulsive force in the first magnet part 30, the backflow prevention part 20 is rotated only at a certain water pressure or higher to open the discharge port 122a. .

Therefore, it is possible to prevent the backflow prevention unit 20 from being rotated in the direction of opening the discharge port 122a by relatively small and light foreign substances such as food scraps, so that the foreign material is discharged through the discharge port 122a to be drained ( 70) can be prevented from occurring.

Furthermore, when the backflow prevention part 20 is rotated in the direction of opening the discharge port 122a, the repulsive force generated between the first magnet part 30 and the third magnet part 50 and the first magnet part 30 As the repulsive force generated between the second magnet parts 40 pushes the first magnet part 30 more strongly to distal the backflow prevention part 20, it is possible to effectively block the odor and wastewater from flowing backward. I can.

Additionally, a handle 51 in the shape of a protrusion having a diameter smaller than that of the third magnetic portion 50 is formed in the center of the third magnetic portion 50.

Accordingly, the user can hold the handle 51 and receive or withdraw the third magnetic portion 50 in the receiving groove 12b.

In addition, the handle 51 is formed to have the same polarity as the third magnetic portion 50 so as to generate an attractive force on the first magnetic portion 30.

On the other hand, the spacing adjustment part 60 is formed in a ring shape and mounted on the outer surface of the third magnetic part 50, and a thread 61 is formed on the outer periphery thereof.

In addition, a thread 121b is formed on the inner periphery of the receiving groove 12b, which is engaged with the thread 61 of the gap adjusting part 60.

Further, although not shown in the drawings, a straight groove or a cross groove may be formed in the handle 51 of the third magnet part 50.

Therefore, by rotating the handle 51 in the forward or reverse direction with a flat screwdriver or a cross screwdriver to adjust the distance between the at least one third magnet part 50 and the first magnet part 30, the first magnet part 30 The intensity of the repulsive force of the third magnetic unit 50 transmitted to the third magnet unit 50 may be varied.

For example, when the handle 51 is rotated in the forward direction, the third magnetic portion 50 is drawn more into the receiving groove 12b to be further away from the first magnetic portion 30. In this case, since the repulsive force of the third magnet part 50 transmitted to the first magnet part 30 is weakened, the backflow prevention part 20 is rotated relatively easily by the drain water to open the discharge port 122a. It will be ordered.

In addition, when the third magnet part 50 is rotated in the reverse direction, the third magnet part 50 is moved in a direction in which the third magnet part 50 is pulled out from the receiving groove 12b to become closer to the first magnet part 30. In this case, since the repulsive force of the third magnetic portion 50 transmitted to the first magnetic portion 30 is increased, the backflow preventing portion 20 may not be rotated under a predetermined pressure.

Accordingly, the opening force and the return force of the reverse flow prevention unit 20 may be selectively adjusted and used by adjusting the distance between the first magnet unit 30 and the third magnet unit 50 in the above-described manner.

Those of ordinary skill in the art to which the present invention belongs will be able to understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. Therefore, it should be understood that the embodiments described above are illustrative and non-limiting in all respects. The scope of the present invention is indicated by the scope of the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the scope of the claims and their equivalent concepts are included in the scope of the present invention.
