Apparatus for Supplying Power to Interior of Drum Body of Drum Washing Machine, and Washing Machine

An apparatus for supplying power to interior of a drum body of a drum washing machine, comprising:

• an inner drum, configured to accommodate clothes;
• an outer tub, mounted at an outer side of the inner drum;
• a tripod, fixedly connected with a bottom of the inner drum to transmit a rotation driving force to the inner drum, wherein an end portion of the tripod extends along an axial direction of the inner drum and penetrates through the outer tub to form a rotating shaft;
• a conductive ring, fixed to an end portion of the rotating shaft and electrically conducted with a functional assembly inside the drum body of the washing machine;
• a bearing, wherein an inner ring is fitted and fixed to an outer wall of the conductive ring, and the bearing is configured to achieve synchronous rotation of the conductive ring with the inner ring of the bearing;
• and
• at least one circuit board assembly, electrically connected with a main control board of the washing machine and mounted on an outer ring of the bearing, wherein electrical connecting ends are formed on the circuit board assembly and configured to be connected with the conductive ring,
• wherein in a process that the conductive ring rotates relative to the circuit board assembly, the electrical connecting ends are configured to be always in contact with the conductive ring to achieve power supply to the functional assembly inside the drum body of the washing machine.
