Generally, a drain is formed on the floor of a sink, toilet, bathroom, or utility room to discharge waste water. This drain is connected to a drain pipe buried in the floor, and the drain pipe is connected to a sewer pipe connected to the lower floor to discharge domestic sewage. .

Therefore, problems may arise where foul odors from sewer pipes enter the drain or pests enter through these drain pipes.

Additionally, in the case of buildings located in low-lying areas, sewage may backflow into drains due to heavy rain during the summer rainy season.

Therefore, recently, in order to prevent backflow and the inflow of bad smells, a drain trap is installed in a housing made of a pipe body in which a pivoting cover folded by a hinge part automatically opens and closes by its own weight. The drainage structure of this drain trap prevents water from entering. When draining, the rotating cover is automatically lifted and opened by the pressure of the water flowing, and when the water is discharged, it is automatically closed again by its own weight, preventing bad odors and the inflow of pests from the sewer pipe as well as the backflow of sewage. It was made so that it could be done.

For example, in Republic of Korea Patent Publication No. 10-2016-0020902, as shown in Figure 1, the opening and closing structure of the pivoting cover formed on the drain trap uses a wire to improve resilience and prevent malfunction from getting caught due to water stains. A drain trap that prevents this is disclosed.

A shielding plate 130 is provided inside the housing 110 as shown in FIG. 4 . The shielding plate 130 is a component that divides the internal space of the housing 110 into upper and lower sections, and is configured to guide sewage flowing in through the inlet hole 122 to flow in the right direction and then fall downward.

For this purpose, the shielding plate 130 is configured to be stepped in the embodiment of the present invention, and the right side is designed to have a lower phase than the left side.

In addition, the shielding plate 130 is integrally coupled with the housing 110 to prevent sewage or bad odors from flowing back upward.

An inspection port stopper 140 is provided on the left side of the shielding plate 130. The inspection hole stopper 140 is configured to selectively block the inspection hole (see reference numeral 142 in FIG. 5) through which a perforation is formed in the shielding plate 130 so that the lower space of the shielding plate 130 can be seen. The coupling structure and operation of the inspection port stopper 140 will be described in detail below.

A second grating 150 is installed on the right side of the shielding plate 130. The second grating 150, like the first grating 120, is a component that performs the function of filtering foreign substances contained in sewage, and the sewage flowing into the housing 110 through the inlet hole 122 is discharged into the housing. It once again performs the function of filtering out foreign substances before they flow to the inner lower side of (110).

Accordingly, a plurality of water drop holes 152 are formed in the second grating 150 as well.

Hereinafter, the detailed configuration of the odor blocking device 100 will be described in detail with reference to the attached FIGS. 5 and 6.

Figure 5 shows a perspective view showing the inspection hole stopper 140 and the second grating 150, which are components of the drain odor blocking device 100 according to the present invention, separated, and Figure 6 shows the drain according to the present invention. An internal perspective view with a portion of the housing 110 removed is shown to show the operation of the draw-out member 170, which is a component of the odor blocking device 100.

As shown in the drawing, the inspection hole 142 formed on the left side of the shielding plate 130 can look into the inner space of the housing 110 by removing the inspection hole stopper 140, and at this time, the drain hole can be seen through the inspection hole 142. It becomes possible.

And the internal space of the housing 110 is divided into a drainage space 112 and a water collection space 114 as shown in FIG. 6. The water collection space 114 is a space where sewage that passes through the first grating 120 and falls to the upper side of the shielding plate 130 is collected, and the drainage space 112 is a space where sewage collected in the water collection space 114 flows into the drain. It is a space that passes through before being drained.

And the bottom surface of the water collection space 114 is formed to be round as shown in FIG. 6. This is to solve the problem of foreign substances gathering at the edges and clumping together, and the entire bottom surface of the water collection space 114 is configured to have a curved surface in the front and rear directions.

A partition 116 is provided between the drainage space 112 and the water collection space 114. The partition 116 is erected upward from the center of the inner bottom surface of the housing 110 to partition the water collection space 114 and the drainage space 112.

And the odor blocking plate 160, which is the main component of the present invention, is rotatably installed in the partition 116. The odor blocking plate 160 shields the drain hole 118 drilled in the partition 116, and is configured to selectively rotate by the water pressure of the sewage collected in the water collection space 114 to drain the sewage.

That is, the odor blocking plate 160 shields the drain hole 118 in an inclined state due to its own weight, and when the water collection space 114 is filled with sewage and water pressure is generated, it rotates clockwise with respect to the upper end. By opening the drain hole 118, the sewage inside the water collection space 114 can be discharged into the drain space 112.

For this purpose, the area in contact with the odor blocking plate 160 on the outer surface of the partition 116 is formed to be inclined, and a rotation support part ( 119) has been formed.

A pull-out member 170 is connected to the front center of the odor blocking plate 160. The draw-out member 170 is configured to be flexible, and both ends are coupled to the draw-out member 170 and the inspection port stopper 140, respectively, so that the odor blocking plate 160 can be easily accessed from the outside of the housing 110 without touching it. It acts to separate it to the outside.

That is, the draw-out member 170 has an end coupled to the lower surface of the inspection hatch plug 140, and the other end is connected to the center of the left side of the odor blocking plate 160.

Therefore, when the user opens the inspection port stopper 140 and lifts it upward, a tensile force is applied to the pull-out member 170, and this tensile force is transmitted to the odor blocking plate 160 to lift it. This force causes the upper end of the odor blocking plate 160 to separate from the rotation support 119, and as shown in FIG. 5, the odor blocking plate 160 can be pulled out of the housing 110 through the inspection hole 142. .

The odor blocking plate 160, together with the drawing member 170, can remove foreign substances stuck when being drawn out to the outside, and the user can visually check the condition of the drain hole 118 through the inspection hole 142. It becomes possible.

For this purpose, the odor blocking plate 160 is preferably configured to have a smaller external size than the inspection port stopper 140.

The upper end of the odor blocking plate 160 can be applied in various forms as long as it is within a range that allows the odor blocking plate 160 to rotate when inserted into the rotation support 119. In an embodiment of the present invention, the odor blocking plate ( The upper part of 160) is restrained on both sides by the rotation support 119, and the central part is configured in a "T" shape so that the odor blocking plate 160 can rotate without interference.

" 형태로 더 함몰되어 있다.More specifically, the rotation support portion 119 has a central portion of the upper end of the partition 116 depressed downward to a certain depth, and the edge of the depressed portion is viewed from the side as “

"It is more depressed in shape.

Therefore, even if the odor blocking plate 160 is operated by water pressure, it is caught on the front ledge and is prevented from leaving, and rotation is possible. At this time, the odor blocking plate 160 can be prevented from being separated by the rotation support 119 of the same shape as above.

Of course, when the inspection port stopper 140 is separated from the inspection port 142 and pulled upward, the odor blocking plate 160 is separated from the rotation support member 119 only by the tensile force transmitted through the pull-out member 170.

Hereinafter, the operation of the odor blocking device 100 configured as above will be described with reference to the attached FIGS. 7 to 9.

Figure 7 shows a longitudinal cross-sectional view showing the drain odor blocking device 100 according to the present invention installed, and Figure 8 shows the action of the odor blocking plate 160 in the drain odor blocking device 100 according to the present invention. A vertical cross-sectional view is shown, and Figure 9 shows a vertical cross-sectional view showing the operation of the draw-out member 170 in the drain odor blocking device 100 according to the present invention.

In this state, when sewage collects on the upper side of the first grating 120, the sewage flows out through the inlet hole 122 and is first caught by foreign substances, and the sewage that escapes through the inlet hole 122 are gathered on the upper side of the inspection port stopper (140) and the upper side of the second grating (150).

At this time, since the inspection port stopper 140 is blocking the inspection port 142, water is collected in the water collection space 114 through the falling water hole 152 while moving to the upper side of the second grating 150. And when it falls into the falling water hole 152, foreign substances contained in the sewage are caught secondarily.

When sewage collects to a certain level in the collection space 114 and water pressure is generated, the odor blocking plate 160 rotates clockwise with respect to the rotation support 119 as shown in FIG. 8 to open the drain hole 118. By opening, the sewage inside the collection space 114 is moved to the drainage space 112, and the sewage flowing into the drainage space 112 is immediately drained through the drain.

And when the water pressure inside the water collection space 114 is lowered, the odor blocking plate 160 rotates counterclockwise with respect to the rotation support 119 to shield the drain hole 118, thereby blocking the odor. There will be.

Also, as shown in Figure 8, a weight 166 may be provided on the left side of the odor blocking plate 160 to control the frequent opening of the odor blocking plate 160, and a weight 166 may be provided on the left side of the partition 116. A sealing member 180 made of an elastic member may be provided to block the flow of sewage when the odor blocking plate 160 and the partition 116 come into contact.

The sealing member 180 is installed in the partition 116 in the embodiment of the present invention, but if necessary, it may be configured at the right side edge of the odor blocking plate 160. In this case, the sealing member 180 ) allows cleaning and replacement of the odor blocking plate 160 when it is pulled out to the outside due to the tensile force applied to the drawing member 170.

Due to long-term use, foreign substances such as hair may attach around the odor blocking plate 160. In this case, the user separates the first grating 120 and turns the inspection port stopper 140 to open the inspection port 142.

At this time, when the inspection port stopper 140 is lifted upward as shown in FIG. 9, tension is applied to the draw-out member 170, and the tension is transferred to the odor blocking plate 160 and lifted, causing the odor blocking plate 160 to be lifted. The upper end of (160) leaves the rotation support unit 119 and can come out.

Through this process, the odor blocking plate 160 can be cleaned, and if the odor blocking plate 160 is provided with a sealing member 180, it can also be exchanged.

And since the drain hole 118 is open to the outside, the user can clean it and visually check the condition of the drain hole.

The odor blocking plate 160 is inserted into the inspection hole 142 in the state shown in FIG. 9, and the upper end of the odor blocking plate 160 is held by inserting a finger into the inspection hole 142 and rotating the support 119. Installation is completed by seating it.
