And a plate-shaped bottom plate 11 for finely crushing the processed material in cooperation with the crushing blade 8.

The fixed blade 10 is fixed by sandwiching the protective tube 9 with the bracket.

The bracket 13 has a discharge groove 12 through which crushed crushed material flows from the crushing section together with water to the outside of the disposer, and is shaped so as to include and support the motor 14.

Here, the characteristic structure of the first embodiment will be described. The cylindrical connecting member 4 made of rubber has a lower portion extended, and the bracket 13 has a rising peripheral wall on the outer periphery. The crushing chamber 16 is covered with the peripheral wall of the bracket 13 and the tubular portion of the connecting member 4. Then, the peripheral wall of the bracket 13 and the tubular portion of the connecting member 4 are connected to each other at a portion having the maximum diameter of the crushing chamber 16. That is, the diameter of the cylindrical portion of the connecting member 4 and the portion of the peripheral wall of the bracket 13 facing the crushing chamber 16 increases toward the maximum diameter of the crushing chamber 16.

Due to this structure, the bracket 13
Further, when the connecting member 4 is molded, there is no undercut portion, it can be easily molded, and no post-processing is required for the portion facing the crushing chamber 16. Therefore, it is not necessary to use an expensive member such as a hopper that surrounds the crushing chamber 16 as in the conventional case, and the disposer component cost can be reduced. Further, the connecting member 4 made of rubber extends from the cullan of the sink flange 3 to the upper half of the crushing chamber 16.

Then, the roller chain 6 and the crushing blade 8 are rotated. Then, the roller chain 6 and the crushing blade 8 are opposed to the wall surface of the crushing chamber 16 by the centrifugal force. The thrown-in garbage is first agitated by the agitator 5 and dropped into the lower part of the crushing chamber. After that, the kitchen waste is struck by the roller chain 6 and the crushing blade 8 and the fixed blade 10 are caused by centrifugal force.
Be skipped to. Here, the kitchen waste is roughly crushed by being cut between the fixed blade 10, the roller chain 6 rotating at high speed, and the crushing blade 8. Further, finely crushed between the crushing blade 8 and the notch provided in the peripheral edge of the bottom plate 11 which are close to each other,
The finely ground kitchen waste and water flow down into the discharge groove 12 of the bracket 13. During the crushing, the garbage that is a processed product is pressed against the inner wall surface of the crushing portion and is crushed by the notches of the crushing blade 8, the fixed blade 10 and the bottom plate 11, so that the inner wall surface of the crushing portion is worn. In order to prevent this, the protection tube 9 protects the inner wall surface near the crushing section. The protective tube 9 shown in FIG. 2 has an inward flange, so that the kitchen waste that is hit by the crushing blade 8 is blown upward along the inner peripheral wall of the protective tube 9, but the flange portion of the protective tube 9 Squeezed by crushing blade 8 again
Get hit by. Therefore, the crushing can be performed efficiently and the crushing time can be shortened. Not only in the case where the protection tube 9 has a flange as shown in FIG. 2, a step protruding inward or a shape that narrows as it goes upward may be used. Since the crushing blade 8 rotating at high speed during crushing repeatedly collides with the garbage, the roller chain 6 and the crushing blade 8 are repelled inward in the radial direction, or are directed radially outward and rearward by the centrifugal force. The kitchen waste is crushed while repeating these steps. The movement of the roller chain 6 and the crushing blade 8 vibrates the disposer body. The vibration of the disposer main body is sufficiently absorbed by the connecting member 4 made of rubber which is formed into a bellows shape and covers the upper half of the crushing chamber 16. Therefore, when the vibration of the disposer body is transmitted to the sink 1, the vibration is absorbed by the connecting member 4 and the sink 1 is absorbed.
The vibration transmitted to is extremely small, and the noise and vibration of the kitchen can be considerably reduced.
