  • Patent number: 8365548
    Abstract: An ice making apparatus for a refrigerator, in which an ice bank stores ice and has an opening that discharges ice on its one side. An ejector opens and closes the opening and is rotatably provided at the opening to also eject ice from the ice bank. After completion of an ice discharging operation, a sensor senses a relative position of the ejector against the ice bank and the ejector is controlled to close the opening to the extent necessary.

  • Patent number: 8341972
    Abstract: An apparatus and method for controlling driving of a plurality of fan motors for a refrigerator are provided. When operated, the plurality of fan motors provided in the refrigerator is sequentially operated at certain delay times, to thus improve operation efficiency of the plurality of fan motors. The apparatus for controlling driving of a plurality of fan motors includes blowing devices that supply cool air, a driving device that generates drive signals to drive the blowing devices, a controller that controls operation of the driving device, a power device that provides operation power of the driving device and the controller, and a cutoff device positioned between the driving device and the power device that cuts off noise and a surge voltage introduced from the power device to the driving device.

  • Patent number: 8333306
    Abstract: An ice-making device includes a duct through which ice is dispensed and a duct-covering part opening and closing the duct. When an operation load applied to the duct-covering part while the duct-covering part closes the duct is greater than a preset normal load, the duct-covering part operates to open the duct.

  • Patent number: 8333081
    Abstract: An ice-making device includes a duct through which ice is dispensed and a duct-covering part opening and closing the duct. A sensor part senses whether the duct-covering part closes the duct and a control part controls the duct-covering part to open the duct when the sensor part senses that the duct-covering part fails to close the duct and the duct-covering part has been attempting to close the duct for at least a preset period of time.

  • Patent number: 8240156
    Abstract: An ice-making device that includes a duct through which ice is dispensed and a duct-covering part for opening and closing the duct. An ice conveying part conveys the ice dispensed through the duct. A driving speed of the ice conveying part increases for a previously set initial driving time when the dispensing of the ice starts, and the ice conveying part is driven at a previously set target speed when the initial driving time elapses.

  • Patent number: 7932688
    Abstract: A cleaner that can be operated at motive force of sufficient strength by using a battery voltage as well as by using a AC voltage. The cleaner uses a low-resistance-mode motor to rotate a collecting fan. The low-resistance-mode motor is driven by a motor driver. The motor driver drops a DC voltage converted from the AC voltage, depending on whether the AC voltage is received. Depending on whether the AC voltage is received, the motor driver drives the low-resistance-mode motor using one of the battery voltage and the dropped voltage.
