A crushed material discharge port 8 communicating with the crushed material discharge pipe 7 is provided. Thus, the pulverized material discharge port 8 is connected to the lower portion 1b of the processing tank 1.
Since it is provided in the processing tank 1, the carrying capacity of the processing tank 1 can be maximized. The overflow drain pipe 5 and the crushed material discharge pipe 7 may be provided integrally with the processing tank 1,
Alternatively, it may be attached separately. The crushed material discharge port 8 is provided with a valve 9 for opening and closing the crushed material discharge port 8. This valve 9 opens the pulverized material discharge port 8 when the processing tank 1 is operated by operating the operation switch (not shown), and the pulverized material is discharged during normal drainage (when the processing tank 1 is stopped). It has a role of closing the discharge port 8 to keep a certain amount of water in the treatment tank 1, and the timing of opening the valve 9 may be at the time of crushing raw garbage or after crushing it. Well, it can be appropriately selected as needed.

However, when the water is normally used (when the processing tank 1 is at rest), the valve 9 is closed, so that a certain amount of water is stored in the processing tank 1. Therefore, by inputting the food waste 4 from the opening 2 of the processing tank 1, the food waste 4 can be stored in a place where water is stored. Therefore,
There is an advantage that bad odors are reduced and effective odor elimination can be performed.

When a certain amount of food waste 4 is stored in water, the processing tank 1 is operated to crush and discharge the food waste 4. At this time, if the valve 9 is opened during crushing, the crushed product can be discharged from the crushed product discharge port 8 at the same time while crushing. On the other hand, if the valve 9 is opened after the crushing, the crushed product is produced in a constant amount of water. The dust 4 is crushed and, after crushing, can be discharged from the crushed material discharge port 8. Since the pulverized product discharged from the pulverized product discharge port 8 contains water, the pulverized product is separated from the water by using, for example, a squeezing machine, and only the pulverized product is collected in the dust receiving portion. In this way, since a fixed amount of the garbage 4 can be collected and then collectively processed, there is an advantage that the number of times of operation of the processing tank 1 can be reduced and a water saving effect and a power saving effect can be obtained.

In this embodiment, since the height of the overflow drainage port 6 and the height of the uppermost end of the rising portion 10 are set to a height difference H of at least 10 mm or more, at the time of crushing food waste (when operating the treatment tank 1). While the crushed material can be discharged from the crushed material discharge port 8 to the crushed material discharge pipe 7 side, when water is normally used (when the processing tank 1 is stopped), the rising portion higher than the overflow drainage port 6 is used. Since the water stored in the treatment tank 1 can be prevented from flowing out to the crushed material discharge pipe 7 side by the 10,
Without using the valve 9 in the embodiment of FIG.
The inside can be kept in a state of storing water. Therefore, as in the embodiment shown in FIG. 1, since the food waste 4 can be stored in the place where water is stored, the generation of a bad odor can be effectively suppressed, the odor can be eliminated, and the number of operating times of the treatment tank 1 can be reduced. ,
