Description

Drain Trap Using Buoyancy

(Technology)

The present invention relates to a drain trap, and more specifically, to discharge the drainage by using the opening and closing port that moves up and down in accordance with the change in the balance of the buoyancy received from the drainage of the lower and the load applied by the drainage of the upper portion and the odor backflow from the drainage pipe A buoyant drain trap for blocking.

(Background)

Floors and facilities where water is used, such as bathrooms, toilets, verandas, sinks, and bathtubs, are provided with drain traps to discharge drainage into the drain pipe and to prevent odors from flowing back from the drain pipe.

One of the representative ones of the conventional drain traps that are widely used is a seal type drain trap that prevents backflow of odors by filling sealing water in the drain pipe passage, such as a P trap or an S trap. This seal type drain trap has the advantage that its structure is simple, but when the seal water is evaporated and disappeared, it is taken by the capillary phenomenon. This is a problem that can not block the backflow of odor due to the case that the water is discharged and disappears, and the water is not sucked out by the siphon action when a rapid drainage is made in another adjacent drain. have.

Another conventional drain trap includes a mechanical drain trap that has a resilient backflow cut-off piece in the drain pipe passage to block the drain pipe to prevent odor backflow and to open the backflow cut-off piece by the load of the drainage only when there is drainage. This mechanical drain trap has a problem in that when the backflow cutoff piece is soiled, the backflow cutoff effect is remarkably lowered and the backflow cutoff is impossible when the backflow cutoff piece loses its elasticity.

Another conventional drain trap is 'sewage backflow and odor blocking device' registered as Utility Model Registration No. 20-163755 on October 4, 1999. This drain trap connects the actuator and the valve body with a number of gears (rack and pinion) so that when the load is applied by the inflow of the drainage, the valve body opens to discharge the drainage. It is configured to block. However, the present gear drain trap has a problem in that its structure is very complicated and the gears are not operated when the gear is caught in the foreign body so that the backflow of odor cannot be blocked.

An object of the present invention is to solve the problems of the conventional drain traps as described above, easy to assemble and disassemble, there is no fear of failure, and there is a fear of failing to block backflow of odor due to evaporation or dirt jam of the water Is to provide a drainage trap of a new structure using little buoyancy.

According to the present invention, there is provided a buoyancy drain trap comprising a drain receiving part, an opening and closing hole and a drain plate.

The drain receiving portion may hold a certain amount of drainage and the upper portion is open so that the drainage exceeding the receiving capacity flows into the drainage pipe. The opening and closing port moves up and down in accordance with the change in the balance of the buoyancy due to the drainage received in the drainage receiving portion and the load of the drainage flowed from above, and in cooperation with the drainage plate to discharge the drainage into the drain pipe while blocking the backflow of odor . The drain plate is formed with a drain opening is closed and open in accordance with the vertical movement of the opening and closing port.

Preferably, the circumference of the waste accommodating portion may be provided with a grill portion for filtering foreign matter from the drain flowing out of the drain pipe. In addition, by forming a guide groove in the opening and closing portion and the guide rod is formed in the drain receiving portion, it can be installed so as to move the opening and closing portion up and down while the guide groove is inserted into the guide rod.

The opening and closing portion is formed so as to bias the main portion to form a buoyancy downward so that the main portion to form the buoyancy is submerged in the drainage of the drain receiving portion, it is possible to minimize the buoyancy change due to the vertical movement of the opening and closing portion Do. In addition, it is preferable to form a water retaining groove in the opening and closing portion in which drainage is temporarily delayed.

Hereinafter, with reference to the accompanying drawings will be described in detail the buoyancy drain trap according to the present invention. The following embodiments are merely illustrative of the buoyancy drain trap according to the present invention, and are not intended to limit the scope of the present invention.

Figure 1 is an exploded perspective view of an exemplary drain trap according to the present invention, Figure 2 is a construction cross-sectional view of Figure 1, Figure 3 is an exploded perspective view of another exemplary drain trap according to the present invention, Figure 4 is a construction cross-sectional view of Figure 3, Figure 5 is a schematic operation of the drain trap according to the present invention.

As shown, the buoyancy drain trap 1 according to the present invention is basically configured to include a drain receiving portion 10, opening and closing portion 20 and drain plate 30.

Drainage receiving portion 10 can accommodate a certain amount of drainage (W) flowed from the floor of the bathroom, such as the drain trap 1 is installed, and drainage (W) exceeding the storage capacity overflows to the drain pipe (2) It has a container shape with an upper portion open to exit, for example, a normal container.

The drainage receiving portion 10 is inserted into and installed in a drain pipe (a sleeve, which is the same below) when the drain trap is installed through a drain trap installation sleeve without directly installing the drain trap. The drainage capacity of the drainage receiving part 10 is determined according to the size of the drainage pipe 2 in which the drainage trap 1 is installed and the capacity of the drained water, and the diameter of the drainage receiving part 10 is sufficient. It is formed to a diameter sufficiently smaller than the diameter of the drain pipe 2 so that it can be inserted into the drain pipe 2 with a margin. The structure for mounting the drainage accommodating part 10 to the drainage pipe 2 is not particularly limited, and for example, an extension part 11 that is expanded around the drainage accommodating part 10 is formed and the extension part 11 is formed. Can be mounted over the drain pipe (2).

Preferably, the extension part 11 may be formed of one grill part 11. The grill part 11 forms a passage through which the drainage water W flowing from the drainage receiving part 10 or flowing directly from the bottom of the bathroom is discharged to the drainage pipe 2, and the hair or fluff included in the drainage water W is formed. Filter foreign matters such as to support the drainage receiving portion 10 to the drain pipe (2). Accordingly, the grill part 11 is formed with drainage holes 12 for drainage, and the outermost circumference of the grill part 11 is provided with a drain pipe so as to mount the drain accommodating part 10 to the drain pipe 2. It has a diameter corresponding to the diameter of 2).

The grill portion 11 is preferably a funnel shape of the upper and lower straits widening toward the upper side for smooth drainage, the upper end of the grill portion 11 is formed with a step (13) to the drain receiving portion 10 to the drain pipe (2) ) Can be mounted over.

The illustrated embodiment shows an example in which the drain trap 1 of the present invention is mounted using a separate adapter 40 instead of directly mounted to a drain pipe 2 or a sleeve, and the drain receiving part 10 is The stepped portion 13 of the grill portion 11 is separably mounted to the drain pipe 2 by hanging on the locking step 41 of the adapter 40.

The opening and closing portion 20 is a member that receives buoyancy from the drainage (W) accommodated in the drainage receiving portion 10, while receiving a load from the drainage (W) flowing through the drainage plate 30 from the bottom of the bathroom, etc., It moves freely up and down in accordance with the balance change of the buoyancy and load.

The shape of the opening / closing opening 20 moves up and down in accordance with the change of the buoyancy and load while cooperating with the drainage plate 30 to discharge the drainage W into the drainage pipe 2 as described later. It is not particularly limited as long as it can block the malodorous backflow of the product. The opening / closing opening 20 has a hollow 21 which can receive a predetermined buoyancy therein while the upper surface 22 has a shape that can be in close contact with the drain opening 31 of the drain board 30 described later. It is preferable.

1 and 2 illustrate the spherical opening and closing hole 20A, and FIGS. 3 and 4 illustrate the cylindrical opening and closing hole 20B.

The spherical opening and closing hole 20A is formed so as to receive a predetermined buoyancy by having a hollow 21 therein, but formed in a complete spherical shape so that the drain opening 31 of the drain opening plate 30 can be formed on any outer surface of the opening and closing hole 20A. It is to block the gap tightly.

The cylindrical opening and closing portion (20B) is to form a hollow 21 in the inside and the overall shape to a cylindrical shape, in the lower center of the opening and closing portion (20B) to form a long guide groove 23 disconnected from the hollow 21 On the other hand it is to form a guide rod 14 upright in the bottom center of the drain receiving portion (10). The opening-and-closing opening 20B is inserted into the guide bar 14 by inserting the guide groove 14 and guided by the guide bar 14 to move up and down. Of course, the upper surface 22 of the cylindrical opening and closing hole (20B) also has a gentle round shape, for example, so as to close the drain hole 31 like the spherical opening and closing hole (20A). According to the configuration of the guide groove 23 and the guide rod 14 as described above, the cylindrical opening / closing opening 20B can move freely up and down, but cannot flow left and right, so that the drain hole 31 of the drain plate 30 to be described later. ) Can be closed more completely.

It is preferable to form a ventilation hole 24 on the upper side of the guide groove 23. The vent hole 24 communicates the inside and the outside of the guide groove 23 so that when the opening / closing opening 20B moves up and down, a higher pressure or a lower pressure than the outside is formed in the guide groove 23 to open and close the opening opening 20B. This is to prevent the damage to Shanghai East.

In addition, the cylindrical opening and closing port (20B) is formed by lowering the weight on the lower side than the upper side or by placing the balance weight 25 in the hollow 21, the tubular opening and closing port (20B) is the waste water (W) used to the drain receiving portion (10) It is desirable to have the same uprightness in the step.

In addition, the main portion for forming buoyancy in the cylindrical opening and closing portion 20B, that is, the main portion for forming buoyancy by forming most of the hollow 21 downwardly in the drainage portion W of the drain receiving portion 10. It is preferable to completely lock, in that the buoyancy change due to the vertical movement of the opening and closing part 20 can be minimized. Accordingly, since the buoyancy increase received by the opening and closing mouth opening 20B is insignificant even when the opening and closing mouth opening 20B descends downward, the downward movement of the opening and closing mouth opening 20B is smooth.

The upper surface 22 of the cylindrical opening and closing port (20B) is preferably formed with a water reservoir groove 26 through which the drain hole 27 is formed. The retaining groove 26 is intended to receive the load of the drainage W for a sufficient time by the opening / closing opening 20B by causing the drainage W flowing down thereon to be delayed for a while.

That is, the drainage W reaching the upper surface 22 of the opening / closing opening 20B lowers the opening / closing opening 20B by applying a load to the opening / closing opening 20, but at the end of the drainage, the drainage W reaching the upper surface 22. Since the amount is very small and the load is insignificant, the opening and closing port 20B may close the drain port 31. However, according to the action of the water retaining groove 26 in which the drain hole 27 is formed, the upper surface 22 for a considerable time until the drainage W accumulated in the water retaining groove 26 exits through the drain hole 27. Since the opening and closing port 20B closes the drain port 31 after all of the waste water is discharged to a slight drain W at the end of the drain, smooth drainage is achieved.

The drain port plate 30 is mounted on the opening / closing opening 20. The drainage plate 30 cooperates with the opening / closing opening 20 to discharge the drainage W introduced from the bottom of the bathroom to the drainage receiving portion 10 and the drainage pipe 2 below, and from the drainage pipe 2. Prevents odor backflow.

A drainage port 31 narrower than the top surface 22 of the opening and closing hole 20 is formed in the center of the drainage plate 30, and the drainage hole 31 is closed or closed according to the vertical movement of the opening and closing hole 20. Open. That is, the balance of the buoyancy due to the drainage (W) of the drain receiving portion 10 applied from the lower side of the opening and closing port 20 and the drainage load flowing through the drain opening plate 30 and applied to the upper side of the opening and closing port 20. According to the change, if the buoyancy of the drainage (W) is relatively large, the opening and closing mouth opening 20 is moved upwards and the upper surface 22 closes the drainage opening 31, and if the load of the drainage is relatively large, the opening and closing mouth opening (20) ) Moves downward so that the upper surface 22 opens the drain hole 31.

The drain plate 30 has a weight enough to overcome the buoyancy of the opening and closing portion 20 so as not to be pushed up by the buoyancy opening and closing portion 20, drainage (W) flowing over the drain plate 30 ) Can be naturally induced into the drain 31, it is preferable that the drain plate 30 is formed in a disk shape of the ordinary light substrait having a gradient lower toward the drain 31.

The lid 50 covering the upper portion of the drain plate 30 in Figure 2, fresh water to block the flow of water when installing the drain trap 1 of the present invention where it is necessary to collect water, such as a sink or bathtub It is a lid.

The buoyancy drain trap 1 of the present invention described above, the adapter 40 is mounted on the top of the drain pipe (sleeve when the drain trap is installed through the sleeve for installing the drain trap), and the adapter ( The drainage receiving part 10 is attached to the 40, the opening and closing hole 20 is mounted on the drainage receiving part 10, and the construction is easily performed by a simple method of mounting the drainage plate 30 on the opening and closing part 20. can do.

Hereinafter, with reference to Figure 5 will be described the operation of preventing the backflow of odor by the action of the drain receiving portion 10, the opening and closing port 20 and the drain plate 30.

In the state where the drain trap 1 of the present invention is installed and the first drainage is not made yet and the drainage receiving portion 10 is not filled with the drainage water W at all, the opening and closing hole 20 is not buoyant. The opening / closing opening 20 is lowered to the lowest position by its own weight, and in this case, the drain opening 31 of the drain board 30 is opened (see FIG. 5A). Then, when the drainage (W) is introduced from the bottom, it flows down through the drainage 31 along the gradient of the drainage plate 30, a part of the drainage (W) is discharged into the drainage pipe 2 as it is, but a part for drainage It is introduced into and received in the portion 10.

As drainage (W) is gradually filled in the drainage receiving portion (10), the opening / closing opening (20) gradually begins to receive buoyancy and moves upwards, but in a state where the drainage (W) continues to flow into the drainage opening (31) (W) applies a load on the upper surface 22 of the opening and closing port 20 to limit the rise, so that the drain 31 remains open and drainage is continued (see FIG. 5B).

A part of the drainage passing through the drainage port 31 and the drainage overflowing from the drainage receiving part 10 are discharged to the drainage pipe 2 through the drainage hole 12 of the grill part 11. The grille 11 is caught. These dirt can be easily cleaned by disassembling the drain plate 30, opening and closing port 20 and the drain receiving portion 10 sequentially.

When the inflow of the drainage water W from the bottom at the end of the drainage becomes insignificant, the load of the drainage water W applied to the upper surface 22 of the opening / closing opening 20 becomes very small, but the load of the drainage water in the water reservoir groove 26 In addition, the opening / closing opening 20 discharges the wastewater flowing in while maintaining a slightly open state without completely closing the drain hole 31 (see FIG. 5C).

Finally, the inflow of drainage W from the bottom is completely intermediate and the drainage of the water retaining groove 26 is also completely discharged through the drainage hole 27 and applied to the upper surface 22 of the opening / closing opening 20. When the load is eliminated, the opening and closing hole 20 is raised by buoyancy and the upper surface 22 of the opening and closing hole 20 to close the drain port 31 (see FIG. 5D).

Subsequently, when the inflow of the drainage water W begins again and the load of the drainage water W is applied to the upper surface 22 of the opening and closing mouth opening 20, the buoyancy is overcome and the opening and closing mouth opening 20 descends to drain again. ) Is drained out (see FIG. 5B).

As described above, the drain trap 1 according to the present invention, when there is an inflow of the drainage (W) from the bottom, the opening and closing port 20 to open the drainage 31 to discharge the drainage, opening and closing when the inflow of the drainage is stopped Buoy 20 is to close the drain 31 to block backflow of odor.

Drainage (W) accommodated in the drain receiving portion 10 in the drain trap (1) of the present invention does not directly block the drain pipe, unlike the water in the conventional seal type drain trap, but provides buoyancy to the opening and closing port 20 By acting to block the drain pipe, as in the conventional Bongsu, when the drainage (W) of the drainage receiving portion 10 evaporates and disappears, the opening / closing opening 20 remains open so that the backflow blocking action of the odor cannot be performed. do. However, in the conventional water-sealed drain trap, the water is directly in contact with outside air having a relatively low vapor pressure (low humidity) and evaporates well, whereas in the present invention, the drainage W of the water receiving portion 10 is opened and closed. Since the surrounding environment of the drainage receiving portion 10 which is completely blocked from the outside air by the buckle 20 and the drainage plate 30 and thus blocked from the outside is relatively high in vapor pressure (high humidity), the drainage receiving portion is substantially The amount of evaporation of the drainage water (10) of (10) is insignificant, so that the failure of the countercurrent blocking of odor due to evaporation hardly occurs.

In addition, since the drain trap 1 of the present invention has a grill portion 11 to which dirt is placed below the drain hole 31, even if dirt is caught on the grill portion 11, the trap is trapped in the drain plate 30. It is not caught between 31 and the upper surface 22 of the opening / closing opening 20. Therefore, the trapped dirt rarely reduces the countercurrent blocking effect or exhausts the drainage water W of the drain receiving portion 10 due to capillary action of these dirt.

In addition, even if a siphon action occurs due to rapid drainage in another adjacent drain, the drainage W of the drain receiving portion 10 is not sucked.

The buoyancy drain trap 1 of the present invention described above is easy to assemble and disassemble, which is convenient for construction and dirt cleaning, and its structure is not complicated, so there is almost no trouble of failure, and the drainage receiving portion 10 Due to the evaporation of the drainage W, the capillary phenomenon of the dirt, and the jam, there is an effect that there is little fear of failing to block backflow of odor.
