In addition, the Korean Utility Model Patent Publication No. 20-2015-0000356 by the present applicant discloses that a sewage induction plate can be formed at the lower part of the pulverizer to shorten the time for pulverizing and discharging the pulverized food garbage, The sewage guide plate is constructed so that the food waste can be drained smoothly without clogging in the drain pipe. When the sewage and the crushed food garbage are dropped downward, the rotating force and the centrifugal force are further improved, The food waste is pushed by the crushing ring due to the rotation force of the driving motor and is crushed while being crushed by the crushing ring by the rotating force of the driving motor. In this way, the crushing ring can be smoothly drained without clogging the drain pipe, As the ring blade is contacted, the food waste is cut and at the same time, The pulverization efficiency can be maximized and the grinding time can be shortened. Further, since the rotational force and the centrifugal force can be improved according to the surface of the grinding ring, Which is disposed in the vicinity of the upper surface of the food waste.

However, the conventional disposer grinding apparatus has a structure in which the pulverizing rotary plate installed to rotate at a high speed in the inner grinding chamber of the main body is inserted into the lower end of the pulverizing ring inserted into the inner circumferential surface of the pulverizing chamber, A hard material such as seeds is caught in the chopsticks or food wastes between the outer circumferential surfaces of the crushing rotary plate and the crushing rotary plate interferes with the operation or the driving motor is overloaded thereby leading to the failure of the disposer.

In addition, a structure in which a plurality of drainage holes are formed in the crushing rotary plate itself such that the crushed product is immediately discharged to the lower side of the crushing rotary plate at the same time as the food is crushed, is not crushed When discharged directly through the drainage port, the length of the fiber is caught by the drainage port, so that the crushed water is not drained due to the closure of the drainage port and is loaded around the drainage port to cause the offensive odor. When the crushed material around the drainage port is hardened There is a problem in that the maintenance and management of the disposing are not easy and in the worse case, the fiber is blocked in the drain pipe or the sewer pipe, so that a separate facility construction is required.

In addition, the structure in which the grinding ring is constrained to the inner circumferential surface of the grinding chamber of the main body causes the disruption of the inner surface of the grinding chamber and the grinding ring fitting structure when the disposer is used for a long time, There was a problem to be done.

In the conventional disposer, since the driving unit and the control unit (or the printed circuit board (PCB)) are usually disposed on the lower side of the crushing chamber (refer to Patent Registration No. 10-1709764), in the process of discharging the wastewater from the upper side crushing chamber There is a problem that moisture which is leaked to the driving unit and the control unit side or generated by the wastewater leaks into the control unit to cause malfunction or failure.
