The present invention relates to a malodor countercurrent prevention plate that is opened and closed automatically by the weight of the weight of the opening and closing plate when water is introduced, and more particularly to adjust the opening limit of the opening and closing plate by varying the position of the weight In addition, when foreign matter is introduced in a certain amount, it is opened and water flows out, and the foreign matter introduced by the outflowing water is also washed down together to keep it completely closed and keep the backflow of odor always in good condition. It relates to a malodor backflow prevention device that can be maintained for a long time.

In general, the odor counter flow prevention device is installed in the drain port to block the gas or odor flowing back from the sewer pipe while draining the water.

Odor reflux prevention device can be classified into two types, spring type and weight type, depending on the operation principle of the switchboard to block odor.

In the spring type, a spring is installed at a hinge portion that enables the opening and closing plate to rotate so that the opening and closing plate opened for drainage by the elastic force of the spring is automatically returned to its original position to maintain the closed state.

In addition, the weight method is to attach the weight to the rear end of the pivotally hinged opening and closing plate so that the opening and closing plate opened for drainage by its weight returns to its original position and remains closed.

In the former type, if the function gradually decreases due to corrosion or loss of elastic force of the spring, the opening and closing plate may have a problem in that the odor flows backward due to a phenomenon in which the closing state gradually becomes poor.

The latter type can maintain a good closed state even if the weight of the weight is maintained even if the corrosion progresses after a long time. However, when the weight is fixed and there is an error in the weight of the weight, the odor blocking function is prevented due to the closing of the closing plate. There is a disadvantage that can not be performed.

In particular, the above two types of malodor backflow prevention device has a disadvantage in that when a foreign material, such as fallen leaves or vinyl, which is introduced with water is caught on the upper surface of the opening and closing plate, a gap is generated as much as the volume of the foreign matter and the odor flows back through the gap.

The present invention has been made to solve the conventional problems as described above, the object is,

The position of the weight can be changed so that the opening limit of the open / close board can be adjusted so that it can always have a good closed state by selecting the weight mounting position according to the site conditions at the time of installation.

Another object of the present invention is to keep a certain amount of water flowing in when it is heavier than the weight of the weight is opened and the water flows out and at the same time the foreign matter accumulated on the top of the switchboard is also swept away along with the water is always in a perfect closed state By maintaining the function to prevent the backflow of odor is always maintained in a good state for a long time.

In another aspect, the present invention, characterized in that the reservoir having a volume for storing the water of the weight or more in the upper portion of the opening and closing plate at the same time the water outlet is provided in the lower front.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side cross-sectional view showing the structure of the malodor backflow prevention apparatus according to the present invention, Figure 2 is a bottom view of the backflow blocking plate of the malodor backflow prevention apparatus according to the present invention.

As shown, the present malodor backflow prevention device includes a main body, an opening / closing plate 30 pivoted on a lower portion thereof, and a weight W for applying a weight to automatically close the opening / closing plate 30.

The main body has a cylindrical shape such as a square or a circle, and has a flange 22 around the upper end thereof, and is mounted on the catching jaw 12 of the inner wall surface of the sump container 10. Here, the upper end of the body is a place where water is introduced, so named 'inlet 24', the lower end is named 'outlet'.

In addition, the opening and closing plate 30 is hinged to one side of the outlet of the main body is rotated. Particularly, the tail portion W is provided with a weight W. As shown in FIG. 2, the long hole 34 is formed to move the position back and forth.

And the weight (W) overlaps one body or several plates to form a block, a bolt hole is formed in the bottom surface by the tightening bolt (B) through the long hole 34 of the rear end of the opening and closing plate (30) Fastening and coupling. Position adjustment of the weight (W) by releasing the tightening bolt (B) to free the weight (W) from the opening and closing plate 30 and then moved to the front and rear opening and closing plate 30 to optimize the weight ratio with the opening and closing plate 30 After adjusting the position, tighten the tightening bolts (B) again and then firmly fix the opening and closing plate (30).

In addition, the weight W has a plate-shaped stopper S having a height. That is, when the opening and closing plate 30 is rotated, the front is lowered by the rotation angle and the rear part, that is, the weight (W) is lifted, and the stopper (S) has a height, so the weight (W) by the rotation angle The upper end of the) is caught by the outer wall surface of the main body 20 so that the open rotation is stopped. In other words, the range of the rotation angle is determined by the height of the stopper (S).

In addition, the upper portion of the main body 20 is guide plate (G) is formed to be inclined toward the rear portion of the opening and closing plate 30 to guide the introduced water toward the rear portion of the opening and closing plate 30, the opening and closing plate from the top 30 will be hidden from view.

That is, when the water flowing into the sump (10) is directly falling into the front end of the opening and closing plate 30, the opening and closing plate 30 is unnecessarily frequently opened due to the falling water shock, the odor is reversed. In order to prevent this to guide the introduced water to the rear portion of the opening and closing plate 30 to minimize the impact of the fall.

3 is a cross-sectional view of the foreign matter blocking plate (P) is installed in the malodor backflow prevention device of the present invention.

As shown, the water guided by the guide plate (G) in the upper body of the opening and closing plate 30 and the lower position of the guide plate (G) to the front end of the opening and closing plate 30 again Plate is installed. This plate is a foreign matter blocking plate (P) to block foreign substances such as fallen leaves and vinyl that flows in with water. Inflow of foreign matter is stuck to the top of the opening and closing plate 30 of the plane is not falling off well, when these foreign matters are accumulated between the outlet 24 and the opening and closing plate 30 causes the closing of the opening and closing plate 30. Done. That is, a gap is generated by the thickness of the foreign matter sandwiched between the outlet 24 and the opening and closing plate 30 so that the odor flows back into the gap.

To prevent this, by installing a foreign matter blocking plate (P) to prevent foreign matter from accumulating on the opening and closing plate (30). In addition, even if the foreign matter accumulated in the opening and closing plate 30 to minimize the discharge distance is accumulated in the front end is to be quickly discharged when opening or closing the opening and closing plate 30 or by the drainage force of water.

Figure 4 is a cross-sectional view of the open water reservoir is installed in the malodor backflow prevention device of the present invention.

As shown, the reservoir 40 is installed on the opening and closing plate 30. The reservoir 40 has a volume capable of storing water equal to or greater than the weight W. And the water outlet 42 is provided in the lower front.

The reservoir 40 is to be stored in the reservoir 40 when water is introduced into the sump (10). When the stored water is filled to a certain level and the weight becomes heavier than the weight W, the opening and closing plate 30 is inclined to open. When the opening and closing plate 30 is inclined, water begins to be discharged toward the front end of the opening and closing plate 30 through the water outlet 42 formed at the lower front side thereof. As the water is discharged, the weight of the reservoir 40 becomes light, but is closed slowly by the inertia force of the water. On the other hand, as the water flows into the water outlet 42 of the reservoir 40, the foreign substances accumulated in the tip are swept away and discharged together, so that the foreign matter does not accumulate in the opening and closing plate 30 as well as between the opening and closing plate 30 and the outlet 24. The phenomenon that the closing defect of the opening and closing plate 30 is caused by the foreign matter is effectively prevented.

Figure 5 is a cross-sectional view of the foreign matter blocking plate is installed on the top of the open water reservoir reservoir of the odor counter flow prevention device of the present invention, the foreign matter blocking plate (P) is introduced into the upper portion of the water reservoir (40) reservoir (40) It is supposed to block the flow into. If foreign matter is introduced into the reservoir 40, because the water outlet 42 formed in the lower front of the front can be blocked and the drainage function can be paralyzed.

On the other hand, the fire-resistant watertight packing 44 is attached to the upper surface of the blocking plate. This is to improve the sealing force with the outlet 24 to increase the backflow prevention effect of the odor.

As described above, in the present invention, since the weight installed at the rear end of the opening and closing plate can change its position back and forth at the rear end of the blocking plate, the opening limit of the opening and closing plate can be adjusted to meet the site conditions at the time of installation. There is an advantage that can be selected the mounting position and thereby reduce the defect by the manufacturing, there is always an advantage that can have a good closed state of the opening and closing plate.

The guide plate which guides the water flowing into the upper part of the opening and closing plate to the rear part of the opening and closing plate has the advantage that the opening and closing plate is opened due to the fall of the impact, thereby minimizing the odor flow back.

In addition, the foreign matter blocking plate is installed to filter out foreign substances introduced with the water, there is an advantage that can maintain a good closed state at all times by blocking the cause of the closing foreign matter caught between the opening and closing plate and the outlet.

It also has a volume to hold more water than the weight of the switchboard, and a water tank with a water outlet is installed at the lower part of the front panel to store a certain amount of incoming water, so that the switchboard is tilted when it is heavier than the weight of the weight. When opened, it is possible to minimize the backflow of odor due to frequent openings by spilling water into the water outlets, and of course, when water flows out through the water outlets, foreign matters accumulated on the top of the opening and closing plate are swept away together and are always perfectly closed. The state can be maintained, and therefore, there is an advantage that it can always maintain the countercurrent blocking function of odor for a long time in a good state.
