  • Patent number: 8621893
    Abstract: A washing machine having balancers and a method of controlling the same is provided. The number of rotations of a motor is maintained at a designated number before excessive vibration of a tub occurs for a designated time in order to prevent excessive vibration of the tub before balls reach a balancing position. The method includes sensing the number of rotations of a motor; determining whether or not the sensed number of rotations of the motor reaches a designated number of rotations by comparing the sensed number of rotations of the motor with the designated number of rotations; and controlling the motor such that the number of rotations of the motor is maintained at the designated number of rotations when it is determined that the sensed number of rotations of the motor reaches the designated number of rotations.

  • Patent number: 8505139
    Abstract: A washer fill system and method supply a suitable minimum amount of water necessary to wash a particular load of laundry based on readings taken from a pressure sensor that measures liquid pressure in the wash tub. Pressure sensor readings are taken intermittently during the fill process to determine when a sufficient amount of free water for washing the load of clothes has accumulated in the tub. This includes pressure readings taken while pulsing the washer motor to spin the wash basket. Other pressure readings may be taken during a pause in filling to measure the water run-off from the wetted clothes above the free water line, and the release of air bubbles from a load portion below the water line. Determining the sufficiency of the amount of wash liquid in the wash tub involves implementation of an algorithm with coefficients determined through regression analyzes, and may include other factors.

    Abstract: An apparatus and techniques for detecting unbalanced load in a washing machine are provided. A clothes basket containing a load of clothing and rotatable about an axis is accelerated. As the clothes basket passes a first predetermined rotational speed, one of power and torque applied to the clothes basket is limited. It is determined whether the clothes basket accelerates from the first predetermined to a second predetermined rotational speed within a predetermined time. Failure to reach the second predetermined rotational speed within the predetermined time signifies an out-of-balance condition as to the load of clothing. No resonance of the machine lies between the first and second predetermined rotational speeds. In another aspect, a similar technique can be employed, with or without limiting power or torque, wherein a resonance does lie between the first and second predetermined rotational speeds.

  • Patent number: 8370981
    Abstract: A method of washing fabric articles in a tunnel washer includes moving the fabric articles from the intake of the washer to the discharge of the washer through first and second sectors that are a pre-wash zone. In the pre-wash zone, liquid is counter flowed in the wash interior along a flow path that is generally opposite the direction of travel of the fabric articles. The fabric articles are transferred to a main wash zone, and a washing chemical is added to the main wash zone. At about the same time, counter flow is reduced or stopped. The main wash zone can be heated as an option. After a period of time (for example, between about 20 and 120 seconds) counter flow is increased. The increased counter flow after chemical treatment amounts to either an intermediate rinse or a pre-rinse depending upon which module or zone the goods occupy.

  • Patent number: 8365334
    Abstract: A washing machine and a method of controlling the washing machine are provided. According to the washing machine and method of controlling the washing machine, the drum is operated at a first speed so that part of laundry within the drum tumbles and another part of the laundry adheres to the drum. When an unbalance amount of the drum operating at the first speed is a first specific value or less, the speed of the drum is increased to a second speed so that all of the laundry adheres to the drum. When an unbalance amount of the drum detected during the increasing to the second speed is a second specific value or more, the rotation of the drum is decelerated. Accordingly, at a time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Patent number: 8365435
    Abstract: A method and apparatus for pressing fluid from laundry articles employs a receiving vessel that holds a batch of articles that are wetted with fluid. Fabric articles are compressed with a press to discharge fluid from the articles. The press includes a diaphragm that can be pressured with fluid. The diaphragm flexibly conforms to an upper surface portion of the batch of fabric articles. After the fabric articles are pressed of fluid, the diaphragm elevates with the press and is rotated. A specially configured linkage rotates the diaphragm and the press as the diaphragm moves from a lower position to an upper position.

  • Patent number: 8353114
    Abstract: An apparatus includes a mechanical refrigeration cycle arrangement in turn including an evaporator, a condenser, a compressor, and an expansion device, cooperatively interconnected. A drum is provided to receive clothes to be dried. An auxiliary heater is included, as is a duct and fan arrangement configured to pass air over the condenser and the heater, and through the drum. A sensor is located to sense high side temperature and/or high side pressure of the mechanical refrigeration cycle arrangement. A controller is coupled to the sensor and the auxiliary heater, and is operative to: activate the auxiliary heater during a startup transient of the mechanical refrigeration cycle arrangement; monitor the high side temperature and/or high side pressure, during the startup transient; and de-activate the auxiliary heater in response to the high side temperature and/or high side pressure reaching a first predetermined value.
