The lid member 52 is connected to the first pipe section 53 (upstream connection pipe section) connected to the microorganism container 15 (decomposition vessel) side and the second pipe section connected to the discharge pipe 9 (sewage pipe 26) side. The two pipes 54 (downstream connection pipes) are integrally formed. The first pipe portion 53 includes a fitting portion 55
It is formed so as to bulge upward from the bottom 55a, and communicates with the opening 59 formed in the bottom 55a. The water channel extends horizontally (in the horizontal direction in FIG. 2) and then bends downward. Have been.

One end of a rubber hose 70 formed of a rubber material such as butyl rubber is fitted into the first pipe portion 53, and is fastened by a band 72 as an attachment member. The other end of the rubber hose 70 is connected to the microorganism container 15 as shown in FIG. Although not shown, a cylindrically projecting pipe portion is integrally formed with the microorganism container 15, and a rubber hose 70 is attached to the pipe portion.
Is fitted at the other end.

The second pipe portion 54 communicates with an opening 60 formed in the bottom 55a of the fitting portion 55, and is formed so that the water channel extends upward and then bends horizontally (in the horizontal direction in FIG. 2). Have been. One end of a rubber hose 71 formed of a rubber material such as butyl rubber is fitted into the second pipe portion 54, and is attached by being tightened by a rubber band 73 as an attachment member. The other end of the rubber hose 71 is connected to the discharge pipe 9 as shown in FIG. Specifically, the discharge pipe portion 9 has a T-shaped portion 9a (see FIG. 1) in which the flow path is formed of ABS resin in a T-shape (trifurcation), and the other end of the rubber hose 71 has a T-shape. The band 9a is attached to one of the openings of the portion 9a.

As shown in FIG. 2, the fitting portion 55 of the lid member 52 is fitted into the opening 51a of the storage portion 51, and is sealed by an O-ring 57 in a watertight manner. Then, when the lid member 52 is fitted into the storage portion 51, the upper surface of the filter member 80 is pressed against the inner wall surface of the bottom portion 55a. As a result, the filter member 80 is
1 is held and fixed.

The lid member 52 is pressed down from above by a pressing portion 81 serving as an attachment member, and
It is held so that it does not come off. Specifically, as shown in FIG. 3, the pressing portion 81 is made of an elastic resin material (A
(BS resin) so as to extend in a substantially U-shape. At a middle portion corresponding to the bottom of the U-shaped pressing portion 81, a concave portion 81b which is substantially V-shaped is formed.
The holding portion 81 has hook-shaped claw portions 81a formed at both ends of the U-shape. On the other hand, a pair of engaging portions 51c with which the claw portions 81a are engaged and fitted are formed on the outer peripheral wall of the storage portion 51.

become that way. That is, the opening 59 on the downstream side of the first pipe portion 53 just overlaps with the opening 80a of the filter member 80 having a cup shape. Further, the opening 60 on the downstream side of the second pipe portion 54 is open to the outside of the filter member 80 in the storage portion 51.

For this reason, the decomposed water flowing through the drain trap section 10 flows as shown by the arrow B in FIG. That is, the decomposed water flows in from the first pipe portion 53, flows horizontally, and then falls downward, and the filter member 80 in the storage portion 51.
Flows into. Then, the flowing decomposed water passes through most of the outer peripheral wall 80b of the filter member 80 as shown by an arrow C in FIG. Thereby, microbial carriers and undegraded garbage in the decomposed water are collected by the filter material 80,
The quality of decomposed water can be improved. Further, in this example, since the filter member 80 is formed of activated carbon, it is possible to remove the odor of the microorganism carrier and the decomposed water.

Then, the decomposed water that has passed through the filter member 80 flows upward as shown by the arrow B in FIG.
After flowing into the pipe part 54 and flowing in the second pipe part 54 in the horizontal direction, it flows into the discharge pipe part 9 and flows into the sewer pipe 26. Thus, in the drain trap section 10,
After the flow path extends downward as shown by arrow B in FIG.
It is formed so as to extend upward in a U-turn, and functions as a trap.

Here, when the filter member 80 is used for a long time, it causes clogging, which causes a reduction in foreign matter removing ability and an increase in water flow resistance. Therefore, maintenance such as replacement of the filter member 80 is required. Further, in the present invention, the filter member 80 may be installed upstream or downstream of the drain trap unit 10 without being installed in the drain trap unit 10. But if you do this,
It is necessary to further subdivide the flow path of the decomposed water, and the structure becomes complicated. Further, the installation space for the filter member 80 increases, which is not preferable.

Therefore, in the present embodiment, the filter member 80 is installed in the drain trap section 10 so as to achieve a simple structure and a reduced installation space. That is, as described above, the drain trap section 10 is mainly configured by assembling the storage section 51 and the lid member 52, and the filter member 80 is detachable by disassembling the drain trap section 10.

Thus, in this embodiment, the filter member 80
When replacing the cover member 5, remove the holding portion 81 and
By removing 2 from storage section 51, filter member 80 can be easily taken out. At this time, the rubber hoses 70, 71 may be removed from the lid member 52, or the rubber hoses 70, 71 may be deformed while the rubber hoses 70, 71 are attached to the lid member 52, and the lid member 52 may be stored in the storage section. 51 may be removed.

In this way, the filter member 8
0 can be simplified, and the installation space can be reduced. Further, since the flow path of the drain trap section 10 is bent as described above, in the conventional apparatus, the microbial carrier or the slimming component contained in the decomposed water easily adheres and accumulates easily. For this reason, the drain trap section 10
Inside, maintenance such as cleaning is required.

Therefore, in this embodiment, since the above-mentioned slime component adheres to the cup-shaped filter member 80, the slime component adhered to the drain trap portion 10 can be reliably removed when the filter member 80 is replaced. Further, since the above-mentioned slimming component adheres to the inside of the cup-shaped filter member 80, the slimming component and the like hardly adhere to the outer surface of the filter member 80. For this reason, the operator grasps the outer surface and
By replacing the filter member 80, it is possible to make it difficult for the operator's hands to get dirty, and it is possible to reduce the discomfort given to the operator.

(Other Embodiments) In the above embodiment, the garbage disposal apparatus 1 is applied to a so-called built-in type installed under the sink 1 in a kitchen cabinet, but the present invention is not limited to this. It can be applied to any garbage disposal device. Further, in each of the above embodiments, the microorganism carrier and the garbage are agitated by the agitating blades 18, but the present invention can be applied even without the agitating blades 18.
