In this way, when food waste (especially long-fiber food waste) moves between the fitting portion 41 and the cutting groove 131, the fitting portion 41 and the cutting groove 131 can cut the food waste with high efficiency. Therefore, the grinding efficiency of the garbage disposer 100 on the food garbage is improved, the time required for grinding the food garbage is reduced, and water and energy conservation are realized.

Thus, in the process of rotating the grinding disc 2 relative to the grinding ring 4, when food waste falls into the gap between the outer peripheral wall of the grinding disc 2 and the inner peripheral wall of the grinding ring 4, the cutting teeth 21 can cut the food waste to crush the food waste, and the crushed food waste is separated downward from the accommodating chamber. Thus, food waste can be prevented from clogging in the gap between the outer peripheral wall of the grinding pan 2 and the inner peripheral wall of the grinding ring 4, which is advantageous in improving the reliability of the waste disposer 100.

In some embodiments of the present utility model, the inner peripheral wall of the grinding ring 4 is provided with a plurality of grinding grooves 44 arranged in the circumferential direction, and the grinding grooves 44 are disposed opposite to the cutting teeth 21.

Thus, in the process of rotating the grinding disc 2 relative to the grinding ring 4, when the food waste falls into the gap between the outer peripheral wall of the grinding disc 2 and the inner peripheral wall of the grinding ring 4, the cutting teeth 21 and the grinding grooves 44 can grind the food waste together, so that the grinding effect of the garbage disposer 100 on the food waste is improved, and the food waste can be separated from the accommodating chamber downwards after being crushed. Thus, food waste can be prevented from clogging in the gap between the outer peripheral wall of the grinding pan 2 and the inner peripheral wall of the grinding ring 4, which is advantageous in improving the reliability of the waste disposer 100.

Further, the grinding groove 44 may be configured to penetrate the grinding ring 4 in the thickness direction, and an upper end of the grinding groove 44 is provided to extend above the grinding pan 2 so that the accommodating chamber may communicate with the outside through the grinding groove 44, so that the grinding groove 44 may grind the food-trash to crush the food-trash and the food crushed to minute particles may escape from the accommodating chamber from directly passing through the grinding groove 44 in a process in which the food-trash rotates along the inner surface of the grinding ring 4. This contributes to an improvement in the crushing efficiency of the garbage disposer 100.
