Description

A DRAINING TRAP

The present invention relates to a drainage trap installed on the floor of a bathroom or a veranda to prevent water from escaping from the drainage pipe while preventing backflow of odor. More particularly, the present invention relates to a " drain trap " that can prevent a deformation of a filter cover exposed at an upper portion even if the user steps on the filter.

Generally, a water collecting tank is installed to collect various kinds of sewage discharged from not only common houses such as multi-family houses and apartments but also households. The bottom of each family bathroom or veranda and the collecting tank are connected through a water pipe (drain pipe) have. In such a drain pipe, a large amount of water and dirt, such as toilet and bathtubs around the living room, together with the odor (odor) can flow backward. In order to prevent backflow of odor (odor) The drain trap is installed.

1, the conventional drain trap is provided with a drain trap main body 1 which is installed directly above a drain pipe (not shown) and in which a through hole 2 is drilled at the center, (3) which is detachably installed on the bottom of the drain trap body (2) while remaining in the bottom of the drain trap body (2) and filled with water of a predetermined height at the bottom thereof, A drainage inducing tube 4 installed to be detachable while being extended and accommodated in the inner space of the drainage residual tube 3 at a lower end portion thereof and a drainage hole 4a provided to cover the upper part of the drainage trap body 1, Is provided with a perforated filter cover (5). The water is collected in the central portion of the drain trap main body 1 through the drain holes 5a of the filter cover 5 and passes through the drain guide tube 4 and is then discharged to the drain pan (3a) to the drain pipe. In the drainage process, dirt such as hair is firstly filtered by the filter cover 5 and is also filtered inside the drainage induction tube 4 and the drainage residual tube 3. Since the bottom of the drain tank 4 is filled with water of a predetermined height and the lower end of the drain tank 4 is always kept in a locked state, the backflow of the odor (odor) from the drain pipe is prevented.

However, in such a conventional drain trap, there is a disadvantage that it is often deformed by an external load after the rectangular cover type sewing cover 5 manufactured by pressing a metal plate is installed. That is, if a drain trap is provided on the floor of a toilet, a veranda, or the like, only the filter cover 5 having the drain hole 5a opened is exposed to the outside, and this condition becomes easy to press. In particular, when the adult touches the central portion of the dirt cover 5 having no separate supporting structure, the dirt can be reduced downward (in the direction of arrow A in Fig. 1).

The present invention addresses this problem. The purpose of the present invention is to provide a "drain trap" capable of effectively preventing the deformation or breakage of the filter cover by separately providing a support structure for holding the filter cover drilled in the drain hole from the bottom to the bottom of the drain trap body .

Another object of the present invention is to provide a " drainage trap " capable of facilitating the disassembly of a drainage inducing cylinder mounted in a threaded manner in cleaning the inside of a drainage trap.

The present invention for achieving this object is as follows. 1. A drainage trap for preventing backflow of odor while being installed on a floor of a bathroom or a veranda equipped with a drain pipe and guiding drainage;

The drain trap; A drain trap main body having an upper surface inclined downward from an edge toward a central portion and having a through hole extending downward at a center thereof; And a water drain hole is formed in the wall of the water hole so as to be filled with a water of a predetermined height, An upper end portion is assembled to the inner wall of the upper end of the tubular coupling member in a threaded manner and a lower end portion thereof is accommodated in the inner space of the drainage remaining tub; A drain cover provided so as to cover an upper surface of the drain trap main body and having a drain hole punctured throughout the drain hole; A support member disposed on an upper surface of the drain trap main body and having a cross shape and having an end seated on an upper edge side of the drain trap main body to support the filter cover; .

In addition, A support leg protruding downward from the upper end of the support member so that the central portion of the support member is spaced apart from the upper surface of the drain trap main body; The supporting protrusions are protruded upward at regular intervals on the inner wall surface of the water guiding tube so as to be inserted into the fitting holes formed at the bottom of the center of the supporting member.

According to the drain trap according to the present invention, Since the support member in the shape of a cross is supported on the upper portion of the drain trap body at the central portion of the filter cover in which the drain hole is perforated, there is an effect that the deformation or breakage of the filter cover is effectively prevented even if the center portion of the filter cover is stepped on.

Further, according to the drain trap according to the present invention, When the inside of the drainage trap is to be cleaned after lifting the filter cover, the drainage guiding cylinder assembled by the screw coupling method can be easily disassembled and disassembled through the support member of the cross shape.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to FIGS. 2 to 5 attached hereto.

As shown in Fig. 2, drainage traps for preventing backflow of odor are installed in the bottom of a bathroom (toilet) or a veranda where a drain pipe is installed, while guiding drainage.

As shown in FIGS. 2 and 3, the drain trap according to the present invention includes a drain trap main body 10 having a generally rectangular shape and having a tube insertion hole 11 extending downward at the center thereof, (20) which is detachably coupled to the tubular coupling (11) of the tub (10), a tubular body A drain cover 40 covering the top surface of the drain trap main body 10 and a support member 40 disposed on the top surface of the drain trap main body 10 to support the filter cover 40 50, the detailed structure of each component is as follows.

First, referring to FIGS. 3 to 5, The drain trap main body 10 is constructed to be embedded in the bottom of a bathroom (toilet) or a veranda equipped with a drain pipe and connected to a drain pipe (not shown). The drain trap main body 10 is made of a synthetic resin material, Is covered with an excellent stainless steel cover material 13 (see Fig. 5). The upper surface of the drain trap body 10 is inclined downward from the edge to the center so as to facilitate drainage. A drain port 11 is formed at the center of the drain trap body 10 so as to extend downward. The reference numeral 12 is a stepped step formed along the upper surface edge of the drain trap main body 10, and the filter cover 40 can be securely seated on the inside thereof without shaking.

As shown in FIGS. 3 and 5, the drainage retainer 20 is formed in a cup shape having an open top and a wall surface 21 and a bottom surface 22, 11 as shown in Fig. A plurality of drainage windows 23 are formed in the wall surface 21 of the drainage remaining trough 20 at a predetermined height from the bottom surface 22 so that the drainage tanks 23 are always filled with water of a predetermined height while drainage is performed. This structure is intended to prevent odor reflux through residual water if drainage is no longer achieved.

As shown in FIGS. 3 and 5, the drainage induction tube 30 is assembled by screwing an upper end portion 31 into the inner wall of the upper end of the tubular coupling hole 11, and a lower end portion thereof is inserted into the inner space of the drainage retainer 20 . The lower end of the drainage inducing cylinder 30 is extended to be positioned below the drainage window 23 of the drainage retainer 20 so that the water flows into the drainage window 23 in a U- So that contaminants such as hair can be filtered. As described above, it is possible to fundamentally block the backflow of odor by the water remaining in the bottom of the drainage retainer 20. When it is desired to remove the dirt trapped in the bottom of the drainage induction cylinder 30, the drainage induction cylinder 30 can be turned and pulled out in the unwinding direction.

As shown in FIGS. 3 and 5, the filter cover 40 covers the upper surface of the drain trap body 10, and drain holes 41 are formed in the whole area. Accordingly, the water drained to the bottom of the bathroom or veranda flows into the drain pipe (not shown) through the drain holes 41 of the filter cover 40, and dirt such as hair is primarily filtered during the inflow. The filter cover 40 is formed by pressing a stainless steel plate having excellent corrosion resistance and is disposed inside the stepped shoulder 12 on the upper surface of the drain trap body 10.

4 and 5, the support member 50 is disposed on the upper surface of the drain trap main body 10 and supports the filter cover 40. The support member 50 is injection-molded through a synthetic resin in a cross- (12) of the upper surface of the drain trap body (10). A support leg 51 is integrally formed at an end of the support member 50 so as to protrude downward from the upper surface of the drain trap main body 10 so that the central portion of the support member 50 is spaced apart. In this way, the support member 50 is formed in a cross shape so as to firmly support the manure cover 40, which is made of stainless steel plate, without being interfered with drainage. The inner wall surface of the drainage induction tube 30 is protruded upward from the inner wall surface of the drainage induction tube 30 at regular intervals so as to be fitted into the fitting holes 52 formed at the center of the support member 50 . In the embodiment of the present invention, four support tines 32 are arranged at intervals of 90 degrees and the central portion of the support member 50 is also supported by the support tines 32 to more firmly support the operation cover 40 can do.

Accordingly, even if the drain hole 41 is stepped on the perforated filter cover 40, it is held firmly through the support member 50, so that deformation or breakage of the filter cover 40 does not occur.

Further, even when the inside of the drainage trap is to be cleaned after lifting the filter cover 40, the drainage induction tube 30 assembled in a screw coupling manner can be more easily disassembled through the support member 50 in the form of a cross shape . Since the end of the support member 50 is in contact with the upper surface of the drain trap main body 10 through the support legs 51 so that the hair that has passed through the drain hole 41 of the filter cover 40, Can be easily caught by the support leg 51 of the support member 50.
