Use of motor power control circuit losses in a clothes washing machine

摘要: In a direct drive clothes washing or cleaning machine, motor power control circuit losses in the form of heat, particularly from switching semiconductors, are advantageously employed for additional heating wash water, thus simplifying necessary heat sinking semiconductor elements as well utilizing otherwise wasted heat. one embodiment, metallic plate like element, example aluminum, has side contact with water. Heat-producing components mounted to other preferably employing bonding techniques wherein conductors bonded non-metallic layer high thermal conductivity and electrical resistivity, alumina (Al 2 O 3 ) beryllia (B e O). Semiconductor bodies conductors, is element.
