Description

{Drain trap for preventing smell backflow}

The present invention relates to a drain trap for odor blocking, and more particularly to a drain trap for preventing odor from flowing back while smoothening drainage.

The drainage trap transfers the sewage generated in the living space to the sewage pipe or the water generated from the road to the desired position such as the sewage pipe. However, there is a possibility that a malodor may occur in a sewer pipe, and this odor may be conveyed backward through a drain trap. To prevent this, the drain trap adopts a structure for preventing backflow of odor.

For example, if a water reservoir is provided in the drain trap and the water stored in the low water reservoir reaches a certain level, the water is passed to the sewer pipe to prevent the odor from flowing back by the water. However, there was a problem that the odor from the water stored in the low water groove can not be prevented from flowing into the living space.

Since the low water reservoir is always in the state of water, contaminants and debris are trapped in the low water reservoir. Generally, drainage traps are embedded in concrete, making it very difficult to clean or replace drainage traps. Accordingly, there is also a problem that odor is generated and transmitted to the living space.

Further, since the drain trap is embedded in concrete or fixed, there is a problem that it is very difficult to perform maintenance if some parts are broken or contaminants and debris are caught. Particularly, there are many cases where hair or the like is interposed between the trap body and the drain pan so that the drain pan does not operate properly.

As shown in the drawings, the drainage trap of the present invention forms the appearance and skeleton of the trap body 10. In the illustrated embodiment, the trap body 10 is formed by coupling the first body 11 and the second body 11 'to each other. However, the first body 11 and the second body 11 'may be integrally formed. When the trap body 10 is composed of the first body 11 and the second body 11 ', the trap body 10 is made completely symmetrical. Accordingly, the first body 11 and the second body 11 'can be formed of one metal mold.

A drainage passage (12) is provided in the trap body (10) to provide a path through which water passes. The structure of the trap body 10 may vary depending on the shape of the drain pan 40, which will be described below, which is installed in the drainage passage 12.

The trap body (10) has an inlet (14). As shown in FIG. 6 and the like, the inlet portion 14 is formed to have a substantially tetragonal flow cross-section on the upper portion of the trap body 10. [ The inlet portion 14 is formed so as to gradually narrow the flow cross-section while going inward.

The trap body 10 has a backflow blocking portion 15 at a position past the inlet portion 14. A drain pan (40), which will be described below, is located inside the backflow barrier (15). A drain pan 40 is located in the backflow blocking portion 15 so that the sewage is sent to the lower portion of the trap body 10 through the drainage passage 12 so that the malodor is not transmitted to the inlet portion 14. For this, the backflow barrier (15) is formed to have a circular section when viewed from one side. The portion of the trap body 10 that has passed through the backflow blocking portion 15 is an outlet portion 16 and is a portion where sewage is discharged through the trap body 10.

A hooking flange 17 is formed along the edges of the inlet portion 14 of the trap body 10 by a predetermined width. The hooking flange 17 is seated on a bottom end of a predetermined space or a seating end formed by an entrance edge of an installation space made on the floor of the road. The hooking flange 17 is hooked on the seat end so that the trap body 10 is positioned in the installation space. For reference, the installation space communicates with the sewer pipe to allow the sewage to be delivered to the sewer pipe.

A hook end 18 is formed along one side of the inlet portion 14 of the trap body 10 and the other side opposite thereto. The hooking end 18 is provided with a guide hole 30 to be described below. The hooking end 18 is made slightly lower than other portions of the upper surface of the trap body 10. [ A hooking jaw 19 is formed along the other side except the portion where the hooking end 18 is formed in the inlet portion 14. [ In the present embodiment, a plurality of the hooking jaws 19 are formed at predetermined intervals.

The shaft insertion channel 20 is formed on the inner surface of the drainage passage 12 of the trap body 10 from the inlet portion 14 to the backflow blocking portion 15. [ The shaft insertion channel 20 has a relatively wide width on the inlet side and an axial hooking portion 22 on the lowermost side to be a portion where the rotation shaft 44 of the drain pan 40 is hooked .

When the first body 11 and the second body 11 'are separated from each other, the hook piece 26 having the hooking jaw 24 is engaged with the first body 11 and the second body 11' Is formed along the tip of the body 11 '. A hooking slot 28 having a hooking jaw 27 is formed at a corresponding position so that the hooking piece 26 having the hooking jaw 24 is hooked therethrough. In this embodiment, the hooking piece 26 and the hooking slot 28 are formed along the surface where the first body 11 and the second body 11 'are coupled to each other. The hooking piece 26 passes through the hooking slot 28 and is engaged with the hooking jaw 24 of the hooking piece 26 by the hooking jaw 27. However, as described above, the first body 11 and the second body 11 'may be integrally formed.

A guide hole 30 is provided at the entrance portion 14 of the trap body 10 so that the edge is hooked to the hook end 18 and the hooking jaw 19 at the entrance portion 14 of the trap body 10 . The guide hole body (32) forms a skeleton of the guide hole (30). The guide body 32 is formed into a hopper shape. A rim 33 is formed along the entrance edge of the guide hole body 32 and an edge of the rim 33 is hooked to the hook end 18 and the hooking jaw 19. The inside of the rim 33 becomes an opening 33 '. The opening 33 'is a path through which wastewater passes.

A guide slope 34, 35, 36, 37 having a predetermined inclination starting from the inside of the rim 33 forms the opening 33 '. In the illustrated embodiment, the tips of the first to fourth guide slopes 34, 35, 36, 37 form the opening 33 '. However, the guide slopes may be formed in a conical funnel shape without the first to fourth guide slopes 34, 35, 36, 37 as shown in the illustrated embodiment. In any case, the tips of the first to fourth guide slopes 34, 35, 36, 37 are made to be in positions corresponding to the inside of the receiving space 47 of the drain pan 40 to be described below. The first guiding slant surface 34 protrudes from the central portion of the entrance part 14 of the trap body 10 more than the other guiding slant surfaces 35, 36 and 37. This is related to the direction of rotation of the drain pan 40 which will be described below wherein the first guide slope 34 with the rotary vane 42 of the drain pan 40 in the direction of gravity is connected to the inlet 14, As shown in Fig. This is to allow the sewage to fall into the recess 43 of the rotary vane 42, which will be described below, into the receiving space 47.

The drain pan 40 is rotatably installed in the trap body 10 so that the water delivered to the inside of the drain canal 12 is transferred to the outlet portion 16 from the outlet portion 16 to the inlet portion 14, And the like.

The drain pan (40) is rotated about the rotation center shaft (44) by a plurality of rotary vanes (42). Both ends of the rotation center shaft 44 are rotatably supported by the trap body 10. The rotation center shaft 44 is seated on the shaft retaining portion 22 of the shaft insertion channel 20 and rotated.

And a plurality of rotary blades 42 are installed around the rotation center shaft 44. [ There are six rotary blades 42 in the illustrated embodiment. The drain pan (40) including the rotary vane (42) may be integrally formed as a whole.

4 and 6, when viewed in the direction of one end of the rotation center shaft 44, the rotation wing 42 starts from the base portion connected to the rotation center shaft 44 to the free end portion And becomes a curve having a predetermined radius of curvature. A reinforcing rib 42 'may be formed on the rotary vane 42. The reinforcing ribs 42 'serve to prevent the shape of the rotary vane 42 from changing and can be used for demolding the drain pan 40 in the mold.

The rotary vane 42 has a concave portion 43 on one side and a convex portion 43 'on the other side by having a predetermined curvature radius from the base to the free end.

The front end of the rotary vane 42 is substantially in close contact with the inner surface of the backflow blocking portion 15 of the trap body 10. When the tip end of one rotary vane 42 is in close contact with the inner surface of the reverse flow blocking portion 15, the tip end of the rotary vane 42 on the opposite side with respect to the rotation center shaft 44, . When the distal end of the rotary vane 42 is displaced from the inner surface of the reverse flow blocking portion 15 in such a state that the rotary vane 42 is rotated and the distal end of the adjacent another rotary vane 42 is in contact with the reverse flow blocking portion 15, As shown in FIG. In this way, the tips of the rotary blades 42 on the opposite sides with respect to the rotation center shaft 44 are always in close contact with the inner surface of the backflow blocking portion 15.

In addition, there is a side plate 46 for connecting both sides of the rotary vanes 42 in the width direction. The side plate 46 is well shown in FIG. The side plate 46 connects the adjacent rotary blades 42 to form a receiving space 47. That is, the receiving space 47 is formed by the adjacent two rotary blades 42 and the side plate 46 connecting them. The sewage filled in the accommodation space 47 is discharged when the rotary vane 42 rotates and the inlet of the accommodation space 47 is located toward the outlet 16.

The side plate (46) has an arched indentation (48). The arc-shaped indentation 48 relatively reduces the size of the entire drain pan 40 including the rotary vane 42 when viewed from one end of the rotation center shaft 44. Since the arc-shaped indentation portion 48 is located in the space between the rotary blades 42, the drain pan 40 can be inserted into and separated from the backflow blocking portion 15 of the trap body 10 do.

Hereinafter, the operation of the drain trap for blocking offensive odor according to the present invention having the above-described structure will be described in detail.

In the present invention, the trap body (10) has a hooking flange (17), so that the trap body (10) can be seated on the seating end of the installation space entrance. Although not shown in the drawings, a shield drain pan (not shown) is provided to cover the entire upper surface of the drain trap including the hook flange 17. The shielding drain plate may be configured to shield only the opening 33 'of the guide 20. Through the shielding drain plate, sewage can be transferred to the opening 33 '.

Most of the sewage flows along the floor or the floor of the periphery where the drain trap is installed so that the first sewage is drained from the first drain port 33 ' Guided along the fourth guide slopes 34, 35, 36 and 37 to the opening 33 '.

As shown in FIGS. 5, 6 and 7, the opening 33 'can send sewage directly to the accommodation space 47 at a position corresponding to the accommodation space 47. Therefore, the sewage is transferred to the receiving space 47 by the guide of the guide hole 30 to rotate the drain pan 40. The sewage transferred to the accommodation space 47 is mainly located in the recess 43 of the rotary vane 42 to cause the rotation of the drain pan 40.

The drainage pan 40 is rotated and the sewage filled in the accommodation space 47 is poured toward the outlet portion 16 of the trap body 10. Particularly, when sewage is seated in the receiving space 47, it is poured only toward the outlet portion 16 without being transmitted to the periphery by the rotary vane 42 and the side plate 46. Therefore, the sewage transferred to the accommodation space 47 is not substantially transferred to the upper portion of the inner surface of the reverse flow blocking portion 15, but flows to the outlet portion 16 via the lower portion.

Therefore, even if foreign matter is mixed in the sewage, it is not present on the inner surface of the trap body 10, and is located on the inner surface adjacent to the lower portion of the backflow blocking portion 15. However, the foreign matter in this position can be easily discharged to the outlet portion 16 by the sewage, so that the rotation of the drain pan 40 is not interrupted.

In the present invention, the hooking flange 17 is hooked on the edge of the installation space where the drain trap is installed. When the opening 33 'of the guide hole 30 is shielded by the shielding drain plate, the installation is completed. Therefore, separation for installation and maintenance of drainage traps can be made very easy.

When the trap body 10 is fixed to the installation space, the guide hole 30 or the shielding drain plate and the guide hole 30 are separated from the trap body 10 and the drain pan 40 And then separated from the shaft retaining portion 22 through the shaft insertion channel 20. In other words, since the drain pan 40 can be separated from the trap body 10, the maintenance work can be very simple.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.

In the illustrated embodiment, the rotary vane 32 is curved with a predetermined radius of curvature from the base to the free end, and is turned by a predetermined angle with respect to the extending direction of the rotary center shaft 31, But it may not necessarily be the case.
