  • Patent number: 11753761
    Abstract: A washing machine and a control method therefor are provided. The washing machine includes a water tank, a washing tub, a pulsator, a drive motor, a coupling flange connected to the drive motor, a drive shaft that rotates the pulsator, a dewatering shaft that rotates the washing tub, a coupler configured to move up and down along the dewatering shaft and to be placed in a first position where the coupler engages the coupling flange and in a second position where the coupler is placed above the coupling flange, a solenoid module that moves the coupler, a coupler guide configured to be rotated by the coupler and fix the coupler in the second position, and a controller configured to control the solenoid module to move the coupler.

  • Patent number: 11408110
    Abstract: A washing machine includes a water tank, a washing tub, a pulsator, a drive motor, a drive shaft, a dewatering shaft that rotates about the same axis of the drive shaft and spins the washing tub, a coupler that is mounted to move up and down along the dewatering shaft and transmits the torque of the drive motor to the dewatering shaft, a solenoid module that moves the coupler upward in a lengthwise direction of the dewatering shaft so as to cut off torque from the drive motor to the dewatering shaft or transmit the torque to the dewatering shaft, when a magnetic field is generated by applying an electric current to a coil, and a coupler guide that rotates itself or fixes the position of the coupler, by coming into contact with the coupler when the coupler moves upward in the lengthwise direction of the dewatering shaft.

  • Patent number: 11293129
    Abstract: A washing machine of the present disclosure includes a drive shaft rotating a pulsator, a dehydration shaft connected to a washing tub, a magnetic core surround a periphery of a solenoid, an armature lifted by an attraction force between the armature and the magnetic corea lever having a support point of which a position is fixed with respect to the dehydration shaft and an operation end located at a point spaced by a predetermined distance from the support point, a clutching coupler shaft-coupling the drive shaft and the dehydration shaft to each other at a lowered position, and shaft-decoupling the drive shaft and the dehydration shaft from each other at a lifted position, an elastic member pressing the clutching coupler downward, a guide groove guiding a relative movement of the operating end with respect to the clutching coupler, and a lowering restriction section disposed in the guide groove.

  • Patent number: 10360452
    Abstract: This disclosure provides a wearable device providing a user with information required for diagnosis and repair of a vehicle using an augmented reality image and receiving a control instruction of the user by a gesture, eye gaze, or speech and a vehicle diagnosis apparatus including the same. The vehicle diagnosis apparatus includes a wearable device configured to acquire a forward image of a user; a controller configured to recognize at least one selected from the group consisting of a gesture and an eye gaze of the user from the forward image and determine a part of a vehicle corresponding to a position of the recognized gesture or the recognized eye gaze; and a communication device configured to transmit a diagnostic trouble code (DTC) request message about the determined part to the vehicle and receive a DTC about the determined part from the vehicle.
