  • Patent number: 7530244
    Abstract: A drum type washing machine includes a housing; a water tub unit accommodated in the housing; a vibration damper, a lower portion thereof being fixed at a base portion of the housing; and a displacement detecting unit for detecting displacement of the water tub unit, the displacement detecting unit being disposed between the water tub unit and the base portion of the housing. The vibration damper supports the water tub unit at a position closer to a front side of the housing than the center of gravity of the water tub unit, and the displacement detecting unit is positioned closer to a rear side of the housing than the vibration damper.

  • Patent number: 7430885
    Abstract: A drum type washing machine includes a housing, a rotary drum, a water tub accommodating the rotary drum therein, a door for opening and closing a housing opening for allowing laundry to be loaded into or unloaded from the rotary drum therethrough, a water tub opening communicating with the housing opening, a rotary drum opening communicating with the housing opening and the water tub opening; and an elastic connection member for connecting the housing opening and water tub opening, and having a portion that makes a pressurized contact with the door when the door is closed. A center of the housing opening is displaced upward with respect to a center of the rotary drum opening, and an angle of inclination of the housing opening with respect to a vertical plane is set to be greater than that of the rotary drum opening with respect to the vertical plane.

  • Publication number: 20060101871
    Abstract: A drum type washing and drying machine includes a cylindrical rotary drum provided with drum perforations and having a rotating shaft in a horizontal or a slanted direction; a water tub, supported in a main body of the drum type washing and drying machine, for accommodating therein the rotary drum; a dehumidification unit for dehumidifying air exhausted from the rotary drum via the water tub; and a blower-heater path communicating with the dehumidification unit and incorporating therein a blower and a heater. The washing and drying machine is also provided with a circulation path for allowing the blower-heater path and the rotary drum to communicate with each other via the water tub. An opening sealing member is installed at a connection opening between the blower-heater path and circulation path such that the opening sealing member is disposed to be rotable in conjunction with an operation of the blower.

  • Patent number: 6966203
    Abstract: A washing-drying machine includes an inner tub having a rotating shaft and sustained rotatably in an outer tub suspended elastically in a cabinet, where an agitator disposed rotatably on an inner bottom of the inner tub. The washing-drying machine also includes a motor for driving the inner tub or the agitator and a warm-air-circulating pass having a heat exchanger cooled by a cooling section. The washing-drying machine further includes a controller for controlling processes including washing, rinsing, dehydrating and drying. The cooling section is formed of a water-cooling-section for cooling warm-air in the heat exchanger by supplying water, and an air-cooling-section for cooling an outer wall of the heat exchanger by blowing air. As a result, high dehumidification rate by improving heat-exchange efficiency of the heat can be obtained, and clothes are hardly damaged and electric power and the amount of water consumption can be saved.
