At this time, the coupling method of the connector 20 and the male part 91 may be applied in various ways in addition to the above-described method, it is not limited to any particular method.

Here, the sink 90 refers to a general kitchen utensil installed in the kitchen to trim, wash or cook the material to be cooked. In addition, the water receptacle 91 means a portion provided at the upper portion of the sink 90 to receive or shed water and to wash and wipe dishes or food.

Through this, food waste may be introduced into the housing 10 through the connector 20.

In addition, the inside of the housing 10 is preferably provided with a fixed grinding sphere 30 and the rotary grinding sphere 40 in order to finely crush the introduced food waste.

First, the fixed grinding sphere 30 is preferably configured to include a guide portion 31 and the enlarged portion (34).

Here, the guide portion 31 is preferably formed in a shape corresponding to the connector 20, through which the food waste introduced into the connector 20 can be guided to the lower side.

In addition, the enlarged portion 34 is preferably extended below the guide portion 31. At this time, the enlarged portion 34 is preferably enlarged to be inclined at a predetermined inclination.

Accordingly, the enlarged portion 34 has a hatshade shape, and the fixed crushing tool 30 has a shape of a funnel as a whole.

In addition, a first grinding protrusion 35 may be formed on the bottom of the enlarged portion 34.

Here, the first grinding protrusion 35 may include a hill 36 protruding in a radial direction, and a valley 37 formed by the hill 36.

Therefore, the food waste having a size larger than the distance D between the fixed grinding hole 30 and the rotary grinding hole 40 in a state that is elastically supported and fixed downward by the elastic member 52 is the fixed grinding. When the inflow between the sphere 30 and the rotary grinding sphere 40, the food waste is contracted by the elastic member 52 by the force pushing up the enlarged portion 34 and the fixed grinding sphere 30 Will move upward.

Then, when the food waste is crushed and the size is reduced so that the force to push up the enlarged portion 34 is no longer, by the elastic force of the elastic member 52 the fixed crushing sphere 30 to move downward again As the fixing block 53 comes into contact with the housing 10, the movement is stopped.

In this way, the fixed grinding sphere 30 is moved in the vertical direction corresponding to the size of the food waste moving between the fixed grinding sphere 30 and the rotary grinding sphere 40 by the variable portion (50) Therefore, it becomes possible to grind without restricting the size of food waste.
