A top-loading-type washing machine including a drum, a drive module for rotating the drum via a drive shaft, inner and outer pulsators placed in the drum so as to be rotated in opposite directions, and a gearbox connected to the drive shaft for rotating both the pulsators. The gearbox includes a sun gear rotatably connected to the drive shaft, planetary gears rotatably engaged with the sun gear, a ring gear rotatably engaged with the planetary gears, a carrier for connecting the planetary gears so as to be rotated along with the planetary gears, a gear housing to which the ring gear is fixed, the gear housing being coupled to the outer pulsator, and a carrier shaft coupled to the inner pulsator. The top-loading-type washing machine further includes a long-axis bolt fastened to the drive shaft and rotatably inserted into a carrier shaft bore of the carrier shaft.

Top-loading type washing machine

A top-loading-type washing machine including a drum, a drive module for rotating the drum via a drive shaft, inner and outer pulsators placed in the drum to be rotated in opposite directions, and a gearbox connected to the drive shaft for rotating both the pulsators. The gearbox includes a sun gear rotatably connected to the drive shaft, planetary gears rotatably engaged with the sun gear, a ring gear rotatably engaged with the planetary gears, and a carrier for connecting the planetary gears so as to be rotated along with the planetary gears. The washing machine achieves excellent washing performance via rotation of the pulsators in opposite directions and variable speeds of the pulsators relative to the drum depending on the size of the laundry load.

Top-loading-type washing machine

A washing machine of the present invention includes: an inner tub receiving laundry; a pulsator rotatably disposed in the inner tub; and guides disposed on the pulsator and guiding washing water, which is turned circumferentially in the inner tub, to the rotational center axis of the inner tub by hitting against the washing water.

Washing machine

Disclosed is a washing machine including an inner tub in which fabrics are accommodated, a fixing hub installed to the inner tub, a rotating shaft configured to penetrate the inner tub and the fixing hub, a sun gear installed to the rotating shaft and having a lower gear portion and an upper pulsator coupling portion, an inner pulsator coupled to the pulsator coupling portion, a plurality of planetary gears engaged with the gear portion and rotatably arranged on the fixing hub, a ring gear having an inner circumferential surface engaged with the planetary gears, a gear box coupled to the ring gear, and an outer pulsator coupled to the gear box, the outer pulsator being larger than the inner pulsator. As the inner pulsator and outer pulsator are rotated at different rates of rotation, complex 3D water stream may be created in the inner tub, resulting in enhanced washing ability.

Washing machine with pulsator and planetary gear device

Provided is a washing machine. The washing machine includes a tub, a drum, a pulsator, a water stream generation unit, a filter cap, and a check valve. The tub contains washing water. The drum is rotatably disposed in the tub and receiving laundry. The pulsator is rotatably disposed inside the drum and has a spouting outlet. The water stream generation unit is disposed under the pulsator and forms a water stream spouted through the spouting outlet by circulating washing water contained between the tub and the drum. The filter cap collects foreign substances floating in washing water spouted through the spouting outlet. The check valve opens the spouting outlet by the water stream formed by the water stream generation unit.

A washing machine includes a cabinet for forming the appearance, a tub provided in the cabinet, a drum rotatably provided in the tub, a pulsator rotatably provided in the drum, a driving motor mounted outside the tub, and rotating the drum and the pulsator, and a water flow forming means provided below the pulsator, and forming a water flow ejected into the drum as an upstream flow.

A washing machine capable of preventing damages of a clutch, a motor, etc., by sensing whether the clutch is normally operated. The clutch transmits a rotational force of the rotor to a dehydration shaft. The washing machine includes a washing shaft configured to rotate a pulsator, a dehydration shaft configured to rotate a drum disposed in a reservoir, a rotor coupled with the washing shaft and configured to transmit a rotational force to the washing shaft, a clutch configured to selectively transmit a rotational force of the rotor to the dehydration shaft a shielding member mounted to the clutch, a magnet provided at the rotor, and a magnetic sensor disposed to face the magnet. The magnetic sensor senses a position of the clutch as the shielding member shields a space between the magnet and the magnetic sensor by a motion of the clutch.
