Washing machine heat dissipation mode and device

The invention provides a washing machine heat dissipation mode and device. A washing machine comprises a washing water tub and a motor. Water in the washing water tub is used for cooling the motor. The washing machine heat dissipation device comprises a heat conductor. One end of the heat conductor is fixed to the motor, and the other end of the heat conductor is arranged in the washing water tub to make contact with the water in the washing water tub. According to the washing machine heat dissipation mode and device, the water in the washing water tub is used for cooling the motor, due to the fact that the water volume in the washing water tub is large, the heat absorption amount of the water is large, more heat of the motor can be absorbed accordingly, the heat dissipation efficiency of the motor is improved, the heat conductor is used for heat conduction, one end of the heat conductor is fixed to the motor, the other end of the heat conductor is arranged in the washing water tub to make contact with the wa
