  • Publication number: 20140318190
    Abstract: The washing machine includes a tub containing wash water, a drum, a lifter, and a partition. The drum rotates inside the tub and has at least one inlet to introduce wash water contained in the tub. The lifter forms a chamber holding wash water introduced through the inlet together with the drum and discharges wash water into the drum through a plurality of discharge holes arranged from a front side to a rear side inside the chamber during the rotation of the drum. The partition divides the chamber into a front chamber and a rear chamber along a longitudinal direction of the drum and forms an angle inclined with respect to a circumference of the drum.

  • Publication number: 20140250951
    Abstract: The present invention provides a laundry processing apparatus (100), which includes: a laundry processing drum (22), used for holding laundry for processing; a driving system (30), used for driving the laundry processing drum (22) to process the held laundry; and a power control system (10), at least used for providing power of a grid for the driving system (30), where the power control system (10) includes an electrical storage device (11). Through the setting, when external grid power outage occur or the fluctuation of the voltage is excessively large, the power control system may switch a power storage device to supply power to the laundry processing apparatus, thereby eliminating the influence on the apparatus caused by unstable voltage of power transmitted by the grid or grid power outage, and avoiding the trouble brought to a user.

  • Patent number: 8820124
    Abstract: A drum type washing machine including a balancer capable of rapidly reducing vibration of a spin tub. The drum type washing machine includes a spin tub which is rotated by receiving rotational force from a driving motor through a rotating shaft, a rear balancer having an annular shape and being coupled to the spin tub, and a shaft flange provided at a center portion thereof with the rotating shaft and coupled to the spin tub so as to uniformly transfer the rotational force to the spin tub. The rear balancer is supported on a rear surface of a rear cover by the shaft flange. Thus, the balls accommodated in the balancer are prevented from moving out of the balancer, even if the balancer is broken due to long-period use.
