The curved portion 146a reduces the flow resistance of the sewage fluid W composed of the food waste and water and induces the vibration caused by the sweeping water W composed of the food waste and the water hitting the annular backflow preventing projecting member And the downward rectilinear portion 146b returns the sewage fluid W composed of the food waste and water induced by the curved portion 146a to the downward direction in the crushing chamber.

The slit portion 146c is formed by being cut in a radially outer direction by a predetermined length from the inner free end of the annular backflow preventing projecting member.

By providing the slit portion 146c in this way, part of the wastewater fluid W composed of the food waste and water that strikes the annular backflow preventing projecting member can be guided through the slit portion 146c to the inside of the pulverizing chamber And the guided sewage fluid W falls down to the lower part of the pulverizing chamber 111 by gravity and the remaining part of the wastewater fluid W is cooled in the crushing chamber 111 along the annular counterflow protruding member, As shown in FIG. That is, the wastewater fluid W can be divided into two flows and returned to the inside of the pulverizing chamber 111, so that the vibration and noise that may be caused by the stagnant fluid W colliding with the annular backflow protruding member can be minimized have.

Preferably, the slit 146c may be formed only in the portion of the downward rectilinear portion 146b out of the curved portion 146a and the downward rectilinear portion 146b. This is because the slit portion 146c must be formed in the downward rectilinear portion 146b so that the sewage fluid W can be guided inward of the crushing chamber 111 not in the upward direction. Namely, the flow path of the wastewater W is limited to the lower side of the horizontal plane of the crushing chamber 111.

In this embodiment, The inner side surface 141a of the crushing chamber 141 is inclined inwardly so that the inner diameter of the crushing chamber 111 becomes narrower from the lower part to the upper part.

12, by configuring the inner surface 141a of the pulverizing chamber 111 as described above, the influence of gravity on the wastewater fluid W can be more strongly exerted. At the same time, as the inner diameter becomes narrower, The wastewater W can be less influenced by the centrifugal force, and the driving force of the wastewater fluid W to rise can be reduced, and the wastewater W can be prevented from flowing backward.

The inside surface structure of the above-described crushing chamber 111 is the same as that of the above-described annular backflow preventing projecting member according to the first embodiment of Fig. 3, the annular backflow preventing projecting member according to the second embodiment of Fig. 6, It is of course possible to apply the present invention to all of the annular backflow preventing projecting members according to the examples.
