摘要： The present disclosure discloses a remote control method for a washing machine, a washing machine and a mobile terminal in wireless connection with the washing machine are used, and the remote control method includes the following steps: a status feedback channel that is between the washing machine and the mobile terminal and that is configured to transmit a working status of the washing machine is established; a control request sent by the mobile terminal is received by the washing machine; and after an activation key disposed on the washing machine is activated, a control channel that is between the washing machine and the mobile terminal and that is configured to transmit a control instruction is established. The remote control method for a washing machine disclosed in the present disclosure, solves the safety problem of the remote control of the washing machine. The control channel that is between the washing machine and the mobile terminal and that is configured to transmit a control instruction can be established only when a person who controls the washing machine in advance pre-ensures that the washing machine is in a safe state or another person ensures that the washing machine is in a safe state, and further triggers the activation key, thereby implementing remote control of the washing machine. The remote control method of the present disclosure improves the running safety of the washing machine.

摘要： Provided are an apparatus for and a driving method of driving a washing machine in which a washing tub is rotated by an inertial force in a freewheeling condition or at a low power driving mode, and a pulsator is reversely rotated, in a state where the pulsator and the washing tub are rotated in one direction. When driving the pulsator and the washing tub in the opposite directions, the inner rotor and the outer rotor are driven in a first direction where the washing tub is rotated, to then set the inner rotor to any one of a free-wheeling mode, an intermittent driving mode, and a low power driving mode, to thus rotate the washing tub, and the outer rotor is driven in one direction opposing the first direction to thus reversely rotate the pulsator.

摘要： A washing machine includes a first washing compartment to hold a first set of articles to be washed and a second washing compartment to holds a second set of articles to be washed, the second washing compartment having an inserted position and a removed position. A liquid flow valve is configured to connect to an external liquid source to selectively control flow of liquid from the external liquid source and into one or more of the first washing compartment and the second washing compartment. An electric motor is configured to rotate the first washing compartment, and the second washing compartment, when the second washing compartment is in the inserted position. A controller, in communication with the electric motor, determines a mass of the second set of articles and then determines, as a function of the determined mass, a volume of water to be added to the second washing compartment.
