Zusammenfassung: | The utility model discloses a control module for a washing machine. The control module comprises a power supply plate, a control board and a radiating fin, wherein a rectification bridge and six IGBT (Insulated Gate Bipolar Translator) modules are arranged on the control board, and the control board is tightly locked on the radiating fin through a screw; the rectification bridge and the six IGBT modules are connected with the radiating fin through heat-conducting silicone grease, and each pin of the rectification bridge is connected with the power supply plate through a short circuit jumper; the control board is further provided with an IGBT driving block and a control chip which is connected with the IGBT driving block, and the IGBT driving block is connected with the IGBT modules. According to the control module, a rectification bridge element and all control circuit IGBT elements share the same radiating fin, so that the cost is reduced, the size of the circuit board is reduced, the structure is simple and |
