Description

[Detailed description of the invention] The present invention is a cesspit that has an invert installed in the middle of a flow path for discharging wastewater from the kitchen or cooking area to the sewer, and has a pocket inside to have a trap function. Concerning improvements to prevent odors from sewers from flowing back into kitchens and cooking areas.

Traditionally, this type of sewage basin has been constructed using a bottomed container with a pocket directly fixed to the inner wall of the sewage basin using an appropriate adhesive or fastener, or the pocket is integrally installed inside the sewage basin made of synthetic resin. The shaped ones are known.

However, in the former case, the installation work of the pocket is extremely troublesome and there are problems in terms of installation strength, while in the latter case, the position of the pocket is fixed, so the method of piping the inflow pipe to the pocket is difficult. It is disadvantageous in terms of manufacturing cost because it is naturally limited and the shape of the mold for molding becomes expensive.

The present invention was developed in view of the above-mentioned circumstances, and attempts to solve the above problems by providing an annular outer frame in the pocket and configuring the outer frame to be attached to the surrounding wall on the side of the sewage basin. .

Hereinafter, the present invention will be explained in detail based on examples.

FIG. 1 is a cutaway front view showing one embodiment of the sewage basin of the present invention, and this sewage basin consists of a fallen tree body 1a, an auxiliary member 1b for adjusting the height above it, and an internal pocket 2. It is made of synthetic resin.

The fallen tree body 1a has a semicircular straight cylindrical invert 10a formed at its bottom, and a pair of sockets 12a communicating with the invert 10a protrude outward from the fallen tree body side peripheral wall 11a. An annular auxiliary phase ring is provided around the upper opening peripheral portion 13a.

The auxiliary material 1b has a lower opening peripheral edge 14b that is similar to the fallen tree body 1a.
The manhole cover 16 or other auxiliary material is fitted into the auxiliary material receiving groove and placed and joined, and the upper end opening periphery 13b has an annular receiving groove for fitting and placing the manhole cover 16 or other auxiliary material. It is surrounded.

Furthermore, a plurality of protrusions 15 are arranged horizontally and radially at appropriate intervals on the inner surface of the side circumferential wall 11b of the auxiliary basin 1b.

The internal pocket 2 consists of a cylindrical body with a bottom as shown in FIG. An annular outer frame 21, which is more dominant than the provided ring body, is integrally formed concentrically with the pocket 2 so as not to be inscribed therein, and so that its upper end is flush with the pocket 2.

The outer diameter of this annular outer frame 21 is set to be slightly smaller than the inner diameter of the auxiliary material 1b.
The pocket 2 provided with the auxiliary frame 1b is attached by inserting the outer frame 21 through the upper opening of the auxiliary frame 1b and locking the outer frame 21 to the protrusion 15 on the inner wall of the auxiliary frame 1b, as shown in FIG.

The pocket 2 may be attached in the same way by providing the protrusion 15 on the side wall 11a of the fallen tree body 1a and locking it in the same way. It may be fixed to the side circumferential wall 11a or 11b) by means of a protrusion 15 or the like.

The sewage basin with the structure as described above is buried underground and constructed by a fallen tree 1a.
At the same time, a small hole 17 is provided in the side wall 11b above the protrusion 15 of the auxiliary member 1b, and the small hole 17 is used for the kitchen or cooking. It is used by inserting an inflow pipe 3 from the field and connecting an L-shaped pipe 31 to the tip of the inflow pipe 3 so that its lower end is located below the upper edge of the pocket 2. Part of the sewage flowing from 3 is stored in the pocket 2, and only the supernatant liquid overflows from the upper edge of the pocket 2, leaving solids such as vegetable scraps in the sewage at the bottom of the pocket 2.

Therefore, the lower end of the slit-shaped pipe 31 of the inflow pipe 3 is always in the sewage collected inside the pocket 2, so that the odor from the sewage pipe 4 will not flow back through the inflow pipe 3 into the kitchen or cooking area. Figure 3 is a cutaway front view showing another typical embodiment of the sewage basin of the present invention, in which the fallen tree body 1a is the same as the embodiment shown in Figure 1, and the auxiliary basin 1b is also , its side peripheral wall 11
b This is the same as the embodiment shown in FIG. 1, except that no protrusions are provided on the inner surface.

The internal pocket 2 is slightly different from that of the embodiment shown in FIG. 1, and has a bottomed elliptical cylindrical body as shown in FIG. It is integrally formed so as to be inscribed in the .

In this case, the pocket 2 may be formed into a donut shape so that its entire circumference is inscribed in the annular outer frame 21, and its inner peripheral wall may be used as an overflow wall.

This annular outer frame 21 is a ring body having the same diameter as the sewage basin, and a receiving groove 211 is provided around the thick upper edge thereof.

Thus, the pocket 2 provided with such an annular outer frame 21 has a third
As shown in the figure, the annular outer frame 21 is fitted and placed on the upper opening periphery 13a of the fallen tree body 1a, and the auxiliary material 1b is fitted and placed in the fitting groove 211 on the upper edge of the annular outer frame 21. By doing so, a pocket 2 is created at the joint between the fallen tree body 1a and the auxiliary material 1b.
It is attached to the sewage basin side peripheral wall with the annular outer frame 21 interposed therebetween.

In the case of a sewage basin in which a plurality of auxiliary materials are stacked on top of a fallen tree body 1a, the annular outer frame 21 of the pocket 2 may be similarly attached to the joint between the auxiliary materials.

In addition, when two or more inflow pipes 3 are inserted into the wastewater basin, two or more pockets 2 are inserted into the tip of the inflow pipe 3, respectively, as shown in FIG. The annular outer frame 21 of each pocket 2 may be stacked so as to be located below the frame 31, and the annular outer frame 21 of each pocket 2 may be attached to the joint between the cage body 1a and the auxiliary material 1b, or the joint between the auxiliary members 1b.

In this case, the diameter of the pocket 2 is set small and the inflow pipe 3
It is desirable to widen the possible range of the mutual piping angle θ to improve piping workability.

In addition, a part of the non-inscribed part of the upper edge of the pocket 2 is cut out to form an overflow groove (not shown), and the overflow is positioned to prevent overflow from occurring over the entire circumference of the upper edge of the pocket 2. It is also desirable to do so.

In the annular outer frame 21 of the pocket shown in FIGS. 2, 4, and 5, the upper and lower middle d are set much smaller than the depth D of the pocket. depth D
It may be larger.

When increasing the size, for example, a plurality of cut grooves or the like are formed on the outer circumferential surface of the annular outer frame 21 at appropriate intervals vertically to facilitate cutting, and the cut grooves are cut at appropriate locations during installation. It is desirable that the height of the pocket 2 can be adjusted.

In addition, although the annular outer frame 21 in the illustrated example is configured to be flush with the pocket 2, it does not necessarily have to be flush with the pocket 2.

For example, it may be flush with the bottom surface of the pocket 2, and can be designed as appropriate within the depth of the pocket.

Furthermore, although the annular outer frame 21 in the illustrated examples is made of synthetic resin or the like and is integrally formed with the pocket 2, it is also possible to attach or detach it from the pocket 2 by making it separately from other materials, for example. Of course, it is also possible to attach it freely.

As can be understood from the above explanation, the sewage basin of the present invention is provided with an annular outer frame 21 in the pocket 2, and this outer frame 21 is connected to the sewage tank using a locking means as shown in FIG. 1 or an intervening means as shown in FIG. Since the pocket 2 is configured to be attached to the basin side peripheral wall 11, it is possible to attach the pocket 2 to the inside of the sewage basin extremely easily and stably. By making it separate from the fallen tree body, you can simply use a conventional sewage basin without pockets and attach Pocket 2 to it. There is no need to separately create a new mold for the entire sewage basin like a basin, and the total mold cost is therefore low, which is advantageous in terms of manufacturing costs.Furthermore, the pocket 2 is provided so as to be inscribed in the annular outer frame 21. In this case, the inlet pipe 3
No matter which direction it is inserted, it can be rotated so that the pocket 2 is positioned below the tip-shaped pipe 31 of the inflow pipe 3. This eliminates restrictions on piping work, and If it is necessary to insert more than one inflow pipe 3,
As shown in FIG.
It is extremely convenient because the annular outer frames 21 can be stacked and attached so that each pocket 2 is located below the annular outer frame 21.

As described above, the sewage basin of the present invention is effective in terms of pocket attachment, manufacturing cost, ease of piping work, etc., and is extremely useful.
