Abstract

The invention relates to a control module for a household kitchen garbage crusher. The control module for the household kitchen garbage crusher is used for controlling a direct current motor in the household kitchen garbage crusher, and is characterized by comprising an microprogrammed control unit (MCU) controller, an electro magnetic compatibility (EMC) circuit, a power sampling circuit, a power conversion circuit, a rectification circuit, a forward and reverse rotation conversion circuit, a first optical coupling isolation circuit, a second optical coupling isolation circuit, a relay driving circuit, a pulse-width modulation (PWM) half-bridge driving circuit and an metal oxide semiconductor (MOS) transistor (Q1). Compared with the prior art, the control module for the household kitchen garbage crusher provided by the invention has the advantages that: the MCU controller outputs a PWM signal, and the PWM signal passes through the second optical coupling isolation circuit and the PWM half-bridge driving circuit to control the MOS transistor, so that the voltage of power supply circuits at the two ends of a motor is adjusted, and a speed regulation function is achieved; and the MCU controller controls the forward and reverse rotation conversion circuit through the relay driving circuit to select the positive and negative polarities of the two ends of the direct current motor, so that the forward rotation or reverse rotation function is achieved.

Description

technical field [0001] The invention relates to a control module for a household kitchen waste shredder. Background technique [0002] Kitchen waste is a kind of organic waste, including leftovers, leftovers, vegetable leaves, fruit peels, eggshells, tea dregs, bones and shells, etc. It generally refers to the source raw materials and finished products (cooked food) or Residues, these kitchen wastes will be corrupted and deteriorated if they are stored for a long time in a humid environment, causing the accumulation of bacteria, leading to environmental pollution in the kitchen, and affecting personal health. Therefore, household kitchen waste shredders have appeared on the market, which can directly cut and pulverize kitchen waste, and then directly discharge it through the sewer. [0003] However, the existing DC motor, which is used as a load in household kitchen waste shredders, mostly has a constant rotational speed, cannot adjust the speed according to actual needs, a...
