Abstract: Provided is a washing machine motor capable of efficiently generating torque by improving a winding factor of coils with a relatively simple configuration. The washing machine motor (12) has an outer rotor (20), an inner rotor (30), and a stator (60). The outer rotor (20) and the inner rotor (30) share coils (63) of the stator (60), and a composite current is supplied to the coils (63) such that the outer rotor (20) and the inner rotor (30) are independently driven. The outer rotor (20) has forty eight outer magnets (24) arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The inner rotor (30) has forty-two inner magnets (34) arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The stator (60) has thirty-six I-shaped cores (61) and the coils (63).

Abstract: A washing machine may include: a hardness component remover including a resin charging chamber between a downstream buffer space and an upstream buffer space and containing an ion-exchange resin; a saturated regeneration water generation vessel in which saturated regeneration water is to be generated; a regeneration water passage connecting the saturated regeneration water generation vessel to the downstream buffer space; a drain passage connecting the upstream buffer space to a drain; a first on-off valve to open and close the regeneration water passage; a second on-off valve to open and close the drain passage; at least one processor; and memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform a regeneration process to regenerate the ion-exchange resin.

Abstract: A drum type washing machine capable of realizing weight reduction and improvement in washing performance at low cost is provided. A drum type washing machine is disclosed. A pulsator is installed rotatably at a bottom of the drum rotatably accommodated in a tub. A motor configured to rotate forward and backward rotationally drives the drum and the pulsator. A control device executes a washing mode in which the motor is driven at a low rotation and a spinning mode in which the motor is driven at a high rotation. The pulsator and the drum have different velocity ratios. A second drive transmission element of the pulsator includes a clutch. Based on executing the washing mode, the drum is rotationally driven while the pulsator is rotationally driven or is allowed to idle. Based on executing the spinning mode, the drum is rotationally driven while the pulsator is allowed to idle.

Abstract: Disclosed herein is a drum type washing machine capable of obtaining a high-water saving effect. The drum type washing machine comprises at least one processor configured to control a drive device configured to rotate a drum, a water supplier configured to supply water to a tub, and a sprinkler configured to spray water stored in the tub toward laundry accommodated in the drum. The drum comprises a lifter and a plurality of rear through-holes. The at least one processor is configured to perform a water spray process while rotating the drum in a state in which an amount of wash water absorbable by the laundry is maintained in the tub, in a washing cycle. In the water spray process, a waiting process, in which driving a circulation pump 91 is stopped, is intermittently and repeatedly performed.
