    Abstract: A control system for a laundry washing machine with a horizontal wash drum detects load imbalance in the drum and selects a proper rotation speed for the drum in a water extraction operation. A drive controller for the motor turning the drum detects a phase angle variation in the drive voltage and drive current applied to the motor as an indication of the load imbalance in the drum, and determines whether the detected load imbalance falls in one of a plurality of pre-defined load-imbalance zones. The drive controller then provides a signal indicating the detected imbalance zone to a machine controller of the washing machine. The machine controller selects a proper rotation speed for the extraction operation based on the detected imbalance zone, or alternatively initiates a load-redistribution operation to reduce the load imbalance.

  • Patent number: 7293436
    Abstract: An improved water supply assembly for a washing machine is provided which prevents breakage of a water supply hose due to freezing. The water supply assembly includes a detergent box assembly provided in a cabinet so as to communicate with a tub of the washing machine, and a water supply valve assembly connected to the detergent box assembly by a hose so as to control a flow of water into the washing machine. By positioning the water supply valve assembly higher than the detergent box, the hose extending therebetween is oriented at a downward slant, thus causing any excess water remaining in the hose after the flow of water into the washing machine has been cut off to naturally drain into the detergent box assembly.

  • Patent number: 7272960
    Abstract: A washing machine is provided which has a structurally reinforced apparatus for accurately sensing a water level. The washing machine includes a housing, a tub installed in the housing, a drum rotatably installed in the tub, and a water level sensing apparatus for sensing a water level in the tub/drum so as to provide an appropriate water level for each washing step. The water level sensing apparatus includes an air chamber installed in communication with the tub. The air chamber stores a predetermined amount such that the water present in the system develops a pressure on the stored air. The water level sensing apparatus also includes a sensor installed at an end of a tube connected to the air chamber which determines a water level by sensing an air pressure in the tube, and a protecting member which prevents disassembly and breakage of the air chamber and the tube during operation of the washing machine.

  • Patent number: 6983628
    Abstract: A washing machine and a method are provided for changing system data which allow a user to identify problems with the product itself, installation, problems due to regional characteristics, changes in use, and the like, and to change system operation data accordingly. A user may change/replace a pre-stored wash program to address specific problems encountered based on user preferences and wash history. An interface section for sending/receiving wash-related data to/from an external device, and a memory for enabling data read/write and for storing data received from the external device are provided to allow for transmission of wash history and receipt and downloading of additional wash programs. Thus convenience, washing performance, and operational efficiency can be maximized, while problem diagnosis and repair performed by the user or service man can be facilitated.

  • Patent number: 6862482
    Abstract: An appliance controller includes a plurality of LEDs that are configured annularly about a control knob of the appliance controller. The LEDs are operated so as to indicate status of the operation of the appliance when the appliance is in a run mode. In one form, the appliance controller illuminates one of the LEDs to indicate at what point the appliance is in its cycle of operation. When the appliance is in a stop mode, the LEDs are operated to indicate where the control knob is positioned when a user is selecting a particular operation with the appliance controller. In one form, as a user rotates the control knob, the appliance controller determines the rotational or angular location of the knob, particularly via a selection indicator of the knob, and illuminates a corresponding LED.
