Description

Drain traps

The present invention relates to a drainage trap, in detail, to have a double closed structure by a float so as to effectively block the inflow of odors or insects from the sewer pipe into the room.

In general, the drain trap induces a smooth drainage flow at the entrance to the sewer pipe in the bathroom floor, and filters foreign substances such as hair and various debris mixed in the sewage to prevent clogging of the sewer. It is used to block entry into the room.

Meanwhile, in the conventional drain trap, a means for preventing the introduction of odors or pests from the sewer pipe has been devised. As a related art, a drain trap such as Patent Documents 1 to 4 has been proposed.

'Drainage trap for preventing backflow of odor' of Patent Document 1 has a structure in which a blocking plate is installed in the sleeve pipe of the drain trap, which is closed by a spring and opened by water pressure.

In the'drainage trap opened and closed by buoyancy' of Patent Document 2, a buoyancy ball with a steel ball inserted inside blocks the drain hole, and when water is discharged, it is pressed and the drain hole is opened. It consists of a closed structure.

The'indoor drainage trap with odor blocking function' of Patent Document 3 is constructed so that a guide support is installed vertically inside the drainage trap, and a cylindrical buoyancy body is raised and lowered by buoyancy and its own weight to open and close the drain hole at the bottom. Has been.

The'drainage trap using buoyancy force' of Patent Document 4 is configured to open the drain hole when the deodorizing cap rises due to buoyancy and descend to close the drain hole when the buoyancy disappears.

On the other hand, in the above-described conventional drainage trap, when the water inside the trap is dried due to various factors such as air flow inside the sewer pipe (wind blowing inside the sewer pipe, etc.) or drying inside the toilet, it is used to block odors and pests. As the water layer disappears, there was a problem that the odor inside the sewage pipe flows into the room, and in the case of blocking odors or pests by the water film, the odor from the water itself flows into the room and pests are trapped in drainage. There was a drawback of not being able to block the flow of the inside through the cold water curtain.

Korean Patent Registration No. 10-1757620 (registered on July 7, 2017) Korean Patent Publication No. 10-2017-0022309 (published on Mar. 2, 2017) Korean Patent Publication No. 10-2017-0064307 (published on June 9, 2017) Korean Open Room No. 20-2011-0005896 (published on June 15, 2011)

The present invention was conceived to solve the above problems, and an object of the present invention is to effectively prevent the inflow of odors and pests from inside the sewer pipe, and to prevent the water inside the drain trap from drying out. It is to provide a drain trap with a structured structure.

In order to achieve the above object, the present invention includes an outer housing having an inclined surface to collect water in an inner center and a drain hole formed in the center; A trap body detachably coupled to the drain hole of the outer housing and having a overflow protrusion formed on the outside at a predetermined height; It is detachably coupled to the drain hole of the outer housing and is installed on the inner bottom of the trap body and the funnel with the lower end formed lower than the overflow jaw of the trap body so as to discharge the water flowing into the drain hole to the trap body. A float that is in close contact with the lower end of the funnel or descends by a load of water; A float ring installed on the upper inner side of the trap body to close the overflow jaw and open the overflow jaw by rising by buoyancy; It provides a drainage trap comprising; a perforated plate detachably placed on the upper portion of the outer housing.

According to the present invention, when drainage is not performed, the two floats close the wall tucks and the funnel, and since a water film is formed inside the trap body, it effectively prevents odors or pests inside the sewage pipe from entering the interior through the drain trap. When draining, the two floats are pushed downwards by the load of water to open the bottom of the funnel and the overflow jaw, so that sewage can be discharged smoothly, and the conventional drainage trap consisting of only the existing simple water layer structure. Compared to that, there is an effect that can improve the performance of blocking odors and pests.

Hereinafter, preferred embodiments that do not limit the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 illustrate a drain trap according to an embodiment of the present invention, and FIGS. 4 and 5 show states when drained and when not drained.

As shown, the drain trap 1 according to the present embodiment has an inclined surface 12 to collect water in an inner center, and an outer housing 10 having a drain hole 14 formed at the center;

A trap body 20 detachably coupled to the drain hole 14 of the outer housing 10 and having a wall flow protrusion 22 formed on the outside at a predetermined height;

It is detachably coupled to the drain hole 14 of the outer housing body 10 and has a lower end portion of the trap body 20 to discharge water flowing into the drain hole 14 to the trap body 20. A funnel 30 formed lower than );

A float 40 installed on the inner floor of the trap body 20 to rise by buoyancy and come into close contact with the lower end of the funnel 30 or descend by a load of water;

A float ring 50 installed on the inside of the trap body 20 to close the overflow jaw 22 and open the overflow jaw 22 by rising by buoyancy;

Consists of including; a perforated plate 60 that is detachably placed on the upper portion of the outer housing 10.

Since the outer housing 10 and the perforated plate 60 have the same structure as the conventional drain trap, a detailed description thereof will be omitted.

In this embodiment, the trap body 20 is the same as the trap body of a conventional drain trap in that the overflow jaw 22 is formed at a predetermined height on the side, but the overflow jaw 22 is a float ring 50 accommodated in the inside. The support rib 24 extends upward radially on the outer periphery of the overflow jaw 22 so that it can be closed by.

In addition, a spring anchoring rib 26 is formed in the center of the inner bottom of the trap body 20 in which a compression coil spring 70 for floating the float 40 with buoyancy is placed.

The funnel 30 has a male screw portion 32 formed at the outer periphery to serve as a kind of fixing nut for fixing the trap body 20 to the drain hole 14 of the outer housing 10, and the funnel body 34 ) Extends downward to form a depth lower than the overflow jaw 22 of the trap body 20 when assembling, and to support the perforated plate 60 at the top of the center and at the same time separate the funnel 30 The handle 36 is protruding for engagement with.

In the drawings, reference numeral 38 denotes a drain hole formed on the side of the handle 36.

The float 40 is inserted into the trap body 20 and rises by the buoyancy of water flowing into the trap body 20 and the restoring force of the compression coil spring 70, and the funnel body 34 Close contact with the bottom of the funnel 30 to block the inflow of odors or pests from the sewer pipe into the indoor toilet, and when draining, the funnel body 34 descends by the load of water located at the top. The lower part is opened so that water (sewage) introduced from the upper part can come down to the trap body 20.

On the other hand, the float 40 is preferably made of foam resin, etc., which has a lighter specific gravity than water, and a flow groove 42 is formed on the side to allow water to flow up and down, and the upper center extends upwardly The handle 44 is formed so that it is easy to hold by hand when disassembling for cleaning.

In addition, the float ring 50 has a through hole 52 formed on the inside so as to be fitted to the outside of the funnel body 34, and is formed to incline upward from the through hole 52 toward the outside, and the float ring ( The outer edge of the trap body 20 is covered with the overflow jaw 22 of the trap body 20 so that the overflow jaw 22 is closed so that the trap is double-closed with the inner float 40 and the trap body 20 ) The trap body 20 and the funnel 30 are blocked by the float ring 50 and the float 40 by allowing odors and pests from the sewer pipe to be kept closed by the water film formed by the water filled inside. You will not be able to pass.

The float ring 50 is also preferably made of the same foam resin as the float 40.

The drainage trap of the present embodiment configured as described above is the main body of the funnel 30 as the float 40 is pressed downward by the weight of water flowing into the funnel 30 from the top as shown in FIG. 4 when draining sewage. (34) The lower end is opened to fill the inner space of the trap body 20, and the float ring 50, which was blocking the overflow jaw 22 of the trap body 20, rises and sews water through the overflow jaw 22. Is discharged to the sewage pipe, not shown.

On the other hand, when the inflow of sewage is cut off from the top after draining, the float 40 rises by the buoyancy and compression coil spring 70 as the weight of water becomes lighter as shown in FIG. As it touches the bottom, it is closed, and the float ring 50 also no longer receives buoyancy. As it descends, it touches the overflow jaw 22 and closes the overflow jaw 22, thereby allowing odors or pests from the sewer pipe to pass through the drain trap. It can be prevented from entering the room.

In addition, in the drainage trap according to the present embodiment, the float 40 and the float ring 50 block the water inside the trap body 20 from contacting the air, so that the interior becomes dry or evaporated by the wind inside the sewer pipe. Since it is also prevented, the closure method by the float and the float ring and the closure method by the water film are combined to more effectively block the reverse inflow of odors and pests, thus further improving the cleanliness of the toilet.
