Motor control circuit of garbage processor and operation control method

Abstract

The invention discloses a motor control circuit of a garbage processor and an operation control method. The method comprises the steps as follows: a motor of the garbage processor is started and begins to run in a forward rotation direction; a forward and reverse rotation control module and a starting module receive a signal that the motor is in an idle state again, the starting module controls the motor to be started, and meanwhile, the forward and reverse rotation control module controls the motor to change an original rotation direction; the forward and reverse rotation control module and the starting module receive the signal that the motor is in the idle state again, the starting module controls the motor to be started, and meanwhile, the forward and reverse rotation control module controls the motor to change the rotation direction again; and a current monitoring module monitors current of the motor in real time and compares the current with a current threshold as follows: if the real-time current is greater than the current threshold, an activation signal is sent out to an unblocking module and the unblocking module is activated to unblock the motor, so that the motor normally works. By the method disclosed by the invention, the rotation direction can be changed when the motor is blocked, automatic unblocking can be carried out and the motor is prevented from being easily burnt out.

Description

technical field [0001] The invention relates to the technical field of garbage disposers, in particular to a motor control circuit and an operation control method of a garbage disposer. Background technique [0002] Household waste, as the main domestic waste, mainly comes from the daily diet, and some fruit peels, melon shells, leftovers, etc. will inevitably be produced in the process. The kitchen waste disposer can effectively dispose of these household wastes that are extremely perishable and breed bacteria. [0003] Currently used garbage processors generally discharge the broken garbage from the sewer pipe, which avoids the collection, shipment and processing of garbage. During the operation of the motor of the garbage disposer, if it is stuck by a hard object, it will be blocked or stuck in place and cannot move. After a long time, the motor is easy to burn out and needs to be repaired. It is inconvenient to use and has a short life. . Contents of the invention ...
