  • Patent number: 10876243
    Abstract: A drum-type washing machine includes an outer tub disposed inside a machine housing a drum disposed in the outer tub and capable of rotating about an axis inclined with respect to a horizontal direction as a center; a rotating body disposed in the drum and having a protruding portion on the surface; a driving portion including a driving motor and is configured to transmit a torque of the driving motor to the drum and the rotor so as to rotate the drum and the rotating body at different rotation speeds; and a controlling portion for controlling an operation of the driving portion. The controlling portion is configured to perform a reduction control for reducing a load when a magnitude of the load applied to the rotating body exceeds a predetermined magnitude in a washing process and/or a rinsing process.

  • Publication number: 20180291546
    Abstract: Disclosed is a purification device, including a case part having an internal space for accommodating an article; and a purification unit disposed in the internal space. The purification unit includes: a flow path provided with a flow inlet and a flow outlet which are in communication with the internal space; a fan enabling air to circulate between the flow path and the internal space; an ozone generating device generating ozone from air; a cover covering the ozone generating device; a supply line taking air from the internal space through an intake port and supplying the air to the ozone generating device; and a guide-in line guiding the ozone generated by the ozone generating device into the flow path. The intake port is exposed outside of the cover to the internal space.

  • Patent number: 9994991
    Abstract: A full-automatic washing machine includes: a first control part, a receiving part, a body display part arranged on an upper panel, and a remote controller separated from the body display part. The remote controller includes: setting keys for setting operating information of a washing operation, a second control part, an information display part and a transmitting part. The second control part displays operating information set by the setting keys through the information display part, and transmits the operating information by the transmitting part to the receiving part through wireless communication. A mode display part of the body display part is illuminated in a color such as blue corresponding to the reception of the operating information until the washing operation starts when the first control part receives the operating information.
