Description

DRAINAGE TRAP

BACKGROUND OF THE INVENTION

Technical Field

The present invention relates to a drainage trap, and in particular to a

drainage trap which is capable of preventing a choked state of a drainage path

and effectively cleaning a drainage trap.

Background Art

A drainage trap is designed to prevent a reverse flow of a bad smell

from a drainage pipe by making a waste water stay in a drainage path. As

shown in Figure 1 , the conventional drainage trap includes a body 2 engaged to

a drainage pipe 7, and a cap 6 engaged to an upper portion of the body 2.

The body 2 of the drainage trap 1 includes a step shoulder 2a on a

surrounding portion of the upper side for mounting a cap 6 thereon. An upper

plate 3 having an upper bent portion 4a is provided in an inner lower portion. A

drainage path 5 is formed between the upper bent portion 3a and the lower bent

portion 4a.

When a waste is flown into the drainage trap 1 , the waste flows onto an

upper portion of the lower plate 4 in the interior of the body 2 and is flown into

the drainage pipe 7 through the drainage path 5 between the lower bent portion 4a and the upper bent portion 3a and is drained to the outside.

In the above conventional drainage trap 1 , when it is used for a long

time, hairs or other solid wastes may be caught by the drainage path 5, so that

the drainage trap 1 may be choked. In the above conventional drainage trap 1 ,

the lower plate 4 and the upper plate 3 are integrally formed with the body 2,

and the body 2 is fixed to the drainage pipe 7, it is impossible to clean the

choked drainage path 5.

Disclosure of Invention

Accordingly, it is an object of the present invention to provide a drainage

trap which overcomes the problems encountered in a conventional art. It is

another object of the present invention to provide a drainage trap which is

capable of effectively cleaning the interior of the drainage trap for thereby

preventing a choking phenomenon of the drainage trap.

To achieve the above objects, there is provided a drainage trap which

includes a body which has a step shoulder formed in a surrounding portion of

an upper side, and a lower side opened cylindrical protrusion provided in a

center portion of the interior of the body, a cap which is mounted on the step

shoulder of the body, and a cover which is designed to have an inner diameter

larger than an outer diameter of the cylindrical protrusion and a height larger than a height of the cylindrical protrusion and which is covered on a surrounding

portion of the cylindrical protrusion in such a manner that a certain gap is

formed between the surrounding portion of the cylindrical protrusion and an

upper side of the same and has a plurality of drainage holes in a surrounding

portion of the same.

In the present invention, the important elements of the drainage trap

through which a waste flows are exposed to the outside by opening the cap and

lifting up the cover, so that it is possible to clean the surrounding portions of the

drainage holes of the cover and the cylindrical protrusion of the body which may

be easily choked by hairs or foreign substances. It is possible to prevent a

choking phenomenon of the drainage trap for thereby enhancing a reliability of

the product.

Brief Description of Drawings

The present invention will become better understood with reference to

the accompanying drawings which are given only by way of illustration and thus

are not limitative of the present invention, wherein;

Figures 1 and 2 are a disassembled perspective view and a cross

sectional view illustrating a conventional drainage trap; and

Figures 3 and 4 are a disassembled perspective view and a cross sectional view illustrating a drainage trap according to the present invention.

Best Mode for Carrying Out the Invention

The features and advantages of the present invention will be described

with reference to the accompanying drawings.

Figure 3 is a disassembled perspective view illustrating a drainage trap

11 according to the present invention, and Figure 4 is a cross sectional view

illustrating an assembled state of Figure 3. There are provided a body 12, a cap

16 and a cover 18.

The body 12 has a flange 12b in an outer portion of an upper side of the

same. A drainage pipe 17 is mounted thereon. A step shoulder 12a is formed in

an inner surrounding portion of the upper side of the body 12. A corresponding

surrounding portion of the cap 16 is mounted and supported thereon.

A cylindrical protrusion 13 having an opened lower side is protruded

from an inner center portion of the body 12. The waste flown into the body 12

through the holes of the cap 16 is drained to the connection pipe 15 through the

cylindrical portion 13.

The cover 18 which is a feature of the present invention is covered on

the surrounding portion of the cylindrical protrusion 13 of the body 12. The inner

diameter of the cover 18 is larger than the outer diameter of the cylindrical protrusion 13, and the height of the same is larger than the height of the

cylindrical protrusion 13. The cover 18 is converted onto the surrounding portion

of the cylindrical protrusion 13 in such a manner that a certain gap is formed

between the surrounding portion of the cylindrical protrusion 13 and the upper

end of the same.

In addition, a plurality of drainage holes 19 are formed in the

surrounding portion of the cover 18, so that the waste flown into the interior of

the body 12 through the cap 16 is flown to an upper side of the cylindrical

protrusion 13 through the drainage holes 19 and is drained to the connection

pipe 15.

In the above drainage trap 11 according to the present invention, when

a waste is flown into the interior of the body 12 through the holes of the

drainage trap 11 , the waste is flown into the space between the cover 18 and

the cylindrical protrusion 13 through the drainage holes 19 of the cover 18 and

is flown into the connection pipe 15 through the drainage port 14 over the

cylindrical protrusion 13 and is drained to the outside.

When the drainage of the waste is completed, since the water is always

stored in the interior of the body 12 by the level corresponding to the height of

the cylindrical protrusion 13, it is possible to prevent a reverse flow of the bad

smell from the connection pipe 15 or the drainage pipe 17. Here, when the drainage trap 11 of the present invention is used for a

long time, hairs or other foreign substances may be choked for thereby

preventing a smooth flow of the waste.

In the present invention, it is possible to simply overcome the problems

that the choked phenomenon occurs in the drainage trap 11 compared to the

conventional art.

Namely, the cap 16 which is simply placed on the step shoulder 12a of

the body 12 is lifted upwardly, so that the cover 18 is exposed to the outside.

Since the cover 18 is not fixed to the body 12 but is simply covered on the

upper side of the cylindrical protrusion 13, it is possible to easily lift without

using a certain tool or using an additional work.

When the cover 18 is simply lifted up, since the cover 18, the drainage

holes 19 and the cylindrical protrusion 13 which are the key elements of the

present invention are exposed to the outside. In this state, the hairs or foreign

substances caught in the surrounding portions are easily removed, so that it is

possible to overcome the choked problems of the drainage trap.

The drainage trap is simply cleaned in the above manner, and then the

cover 18 is placed on the cylindrical protrusion 13, and the cap 16 is placed on

the step shoulder 12a of the body 12.

Therefore, in the drainage trap according to the present invention, since the interior of the same is easily disassembled, it is possible to easily and

simply overcome the choked phenomenon of the drainage trap.

In the present invention, it is possible to simply and quickly overcome

the choked phenomenon of the drainage trap without a special skill or took for

thereby implementing an easier use.

As described above, in the drainage trap according to the present

invention, the important portions of the drainage trap 11 are exposed to the

outside by simply opening the cap 16 and lifting up the cover 18. It is possible to

conveniently and easily clean the surrounding portions of the drainage holes 19

of the cover 18 and the cylindrical protrusion 13 of the body 12 which are easily

choked by hairs or other foreign substances. It is possible to prevent a choking

phenomenon of the drainage trap for thereby enhancing a reliability of the

product.

As described above, the above description is one embodiment for

implementing a hair cutting scissors according to the present invention. The

present invention is not limited to the above embodiment. As the present

invention may be embodied in several forms without departing from the spirit or

essential characteristics thereof, it should also be understood that the above-
