Description

Drain Trap

The present invention relates to a drainage trap, and more particularly, to a drainage trap capable of stably maintaining sealing water and capable of more completely blocking the odor coming from the drainage port.

The drainage trap is installed to prevent the foreign substances contained in the sewage from flowing into the drain pipe while discharging the sewage by connecting it to the drain pipe at the position where water is drained so that the sewage used in the toilet, veranda, and sink is drained. The smell that flows backward from the water pipe by keeping a certain amount of water in a state of being accommodated is blocked so that insects and the like are prevented from flowing into the room.

A conventional drain trap is used in various types according to the size of a drain hole. Such a conventional drain trap has a complicated structure, which is expensive to manufacture, troublesome installation, and can not properly block the smell coming from the drain hole.

Patent Document 1 has been proposed in order to solve the above-mentioned problems, and it discloses a drain trap for blocking the odor that can come from the drain hole (1) by using the seal water (2) A molding sleeve 110 having a drain hole 111 communicating with the drain hole 1 on a surface thereof; And the upper end of which is provided with an upper drain hole 211 so that the lower end thereof is inserted into the drain hole 111 and communicated with the drain hole 1 and water is allowed to flow over the upper end thereof, An insert 210; A watertight packing (410) fitted between the drain hole (111) and the bead insert (210) in a ring shape surrounding the bead insert (210) and disconnecting it from the drain hole (1); And the upper part is closed and the lower part is opened to cover the upper part of the sewing insert 210. The length of the lower part is shorter than the length of the sewing insert 210 exposed to the inner space of the forming sleeve 110, And a seal cap 310 having a fixing pin 311 for inserting an upper end of the seal inserting 210 into an upper surface of the seal cap 310; The sewing cap 310 has a fixed pinch 311 which is biased to one side so that when the pinch cap 310 is fitted to the upper end of the pinch inserter 210, As shown in Fig.

However, in Patent Document 1, there is a problem that the configuration for assembling the bead insert 210 and the bead cap 310 is not simple and assembly is troublesome.

Particularly, a large amount of hair, such as a hair, is discharged to the drain hole. Such foreign matter is not easily discharged, but is spread over the bead insert 210. The hair drains the bead by the capillary phenomenon, There is a problem that it is impossible to shut off odors or insects coming from a drain pipe.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is possible to reduce the manufacturing cost by simplifying the structure, and the cap having the buoyancy is lifted according to the height of the stick to always shut the drain hole and the room, And it is an object of the present invention to provide a drain trap which does not cause the problem that the seals are completely discharged by the hair or the like.

In order to solve the above-described problems, the present invention has a housing having an upper surface opened and connected to a drain pipe at a lower side, and a coupling hole formed at a center of a lower surface thereof; An induction pipe fixedly coupled to the engaging hole and having an upper end positioned in an inner middle of the housing, a rib formed on an outer periphery thereof, and a protrusion having a top surface horizontal and a bottom surface inclined; And a cap which is floated from the upper side of the induction pipe and has a height at least longer than a height of the induction pipe protruded upward from the inside of the housing; And the buoyancy acts on the cap by the sticking water inside the housing to keep the lower end of the cap away from the bottom surface of the housing so that the water is drained to the space between the cap and the induction pipe have.

Preferably, the cap is made of a foamable resin so as to have buoyancy. Alternatively, a space for buoyancy may be formed inside the cap.

The foreign matter such as hair is prevented from sticking to the inner wall of the induction pipe even if the foreign matter such as hair spans the upper end portion of the induction pipe by the protrusion formed on the inner periphery of the upper end of the induction pipe.

The present invention is simple in construction and easy to manufacture and handle, and is lifted and lowered according to the height of the seams by the cap having buoyancy, so that it is possible to more reliably block the smell from the drain port and back flow of the insect, , It is possible to prevent the sticky water from being discharged due to the capillary phenomenon even if a long foreign matter such as hair is caught.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.

In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

In the drawings, the same reference numerals are applied to the same names.

FIG. 1 is a perspective view of a drain trap according to the present invention, FIG. 2 is a partial cross-sectional perspective view of a drain trap according to the present invention, FIG. 3 is an assembled sectional view of a drain trap according to the present invention, Sectional view showing the operation state of the drain trap according to the present invention.

1 to 4, the present invention provides a concrete slab 1, which includes a housing 10, a guide pipe 20 vertically installed in the middle of the housing 10, And a cap 30 which covers the upper side of the cap 30.

The upper end peripheral portion of the housing 10 is embedded in the concrete slab 1 and the lower peripheral portion of the housing 10 is coupled to the drain pipe 2. A coupling hole 11 is formed in the middle of the bottom surface, The induction pipe 20 is installed and fixed.

The induction pipe 20 is installed so as to penetrate the coupling hole 11 of the housing 10 so that no leakage occurs between the coupling hole 11 and the upper end of the induction pipe 20, And the lower end of the induction pipe 20 protrudes to the lower side of the housing 10.

The induction pipe 20 and the coupling hole 11 may be further provided with a separate packing to prevent leakage, and a screw type coupling may be possible.

A plurality of ribs 21 are radially formed on the outer circumference of the induction pipe 20 protruded above the bottom surface of the housing 10 so that the plurality of ribs 21 are firmly engaged with the housing 10 And maintains a constant distance from the cap 30.

The cap 30 is formed in a cylindrical shape having an opened bottom face and is made of a foamed resin and has buoyancy.

The cap 30 is covered on the upper side of the induction pipe 20 and has an inner diameter slightly larger than the rib 21 formed on the outer periphery of the induction pipe 20, Is formed at least longer than the height protruded upward from the inside of the housing 10.

Therefore, the cap 30 is floated in the water by the stick water which becomes high in the inside of the housing 10, and the cap 30 is moved up and down from the outside of the induction pipe 20 according to the water level.

A mesh or a cover may be further provided on the upper side of the housing 10, which is a general matter, and thus a detailed description thereof will be omitted.

The drain trap installed in this way causes the drainage water to flow into the interior of the housing 10, which forms the seal 4 which is held by the induction pipe 20 rising in the middle of the housing 10 The cap 30 is lifted up by the stick 4 so that a gap is formed between the upper end of the induction pipe 20 and the upper end of the inner side of the cap 30, And water of a water level exceeding the upper end of the induction pipe 20 is drained to the drain pipe 2 through the induction pipe 20.

The sewing water 4 is always kept between the bottom surface of the housing 10 and the upper end of the induction pipe 20 so that the water pipe 2 and the room are spatially blocked by the sewing water 4, The smell of insects and insects.

The cap 30 having buoyancy stably induces the drainage of water while maintaining a constant height by the seal 4.

On the other hand, when the water is not drained for a long period of time, the seal 4 is dried. If the seal 4 is not present at all, the lower end of the cap 30 comes into close contact with the bottom surface of the housing 10.

Therefore, in this case, the cap 30 does not block the drain port 3 by sealing, but blocks the room and the drain port itself, thereby preventing the smell and the insects from entering the drain port.

As a result, the drainage trap of the present invention is capable of shutting off the drainage port when there is a seal or no seal.

FIG. 5 shows another embodiment of the present invention. Referring to FIG. 5, a protrusion 22 is formed on the inner circumference of the upper end of the induction pipe 20 according to the present invention.

The protruding portion 22 is formed by a capillary phenomenon in the case where a long foreign object such as a hair hangs over the induction pipe 20 along with the water and hangs over the upper end of the induction pipe 20, The hair is not brought into close contact with the inner surface of the induction pipe 20 by the projecting portion 22 even if the hair extends over the upper end of the induction pipe 20 So that the sewage is prevented from being discharged.
For this purpose, it is preferable that the protruding portion 22 is formed such that the top surface is further protruded in a planar shape as shown in FIG. 5, and the bottom surface is formed as an inclined surface so that its tip end forms a sharp cross section.

FIG. 6 is a sectional view showing still another embodiment of the present invention. As described above, the cap 30 according to the present invention can have a sufficient buoyancy by forming the space portion 31 therein.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. For example, the housing 10, the induction pipe 20, and the cap 30 according to the present invention are passivated in a polygonal shape rather than a cylindrical shape. The shape of the housing 10 is the same as that of the surrounding concrete slab 1 and the drain pipe 2 ) And the like.
