2. Description of the Related Art A disposer is attached to a drain port of a sink, receives kitchen garbage introduced into the crushing chamber together with water from the drain port by a rotary blade plate at the bottom of the crushing chamber, and rotates the rotary blade plate by rotating the rotary blade plate. It is crushed by the upper impact blade and bounced off, or by centrifugal force, crushed by the rotating blade on the outer periphery of the rotating blade plate and the fixed blade surrounding this rotating blade and discharged under the rotating blade plate, but mixed with kitchen waste Spoons and forks,
When hard foreign materials such as crowns or other metal or ceramic pieces are thrown in, these hard foreign materials are blown off by the rotating blade plate and damage the inner wall of the crushing chamber, or are caught between the fixed blade and the rotating blade, causing the blade to bite. In addition to damaging the motor, the rotating blade plate is locked, causing an overload on the motor, and possibly burning the motor.

Therefore, if it is detected that foreign matter has been thrown in due to an abnormal sound or the like hitting the inner wall of the crushing chamber, it is necessary to immediately stop the operation of the disposer and remove the foreign matter. For this reason, Japanese Patent Application Laid-Open No. 55-167
