  • Publication number: 20100037401
    Abstract: A washing machine and a method of controlling the washing machine may be provided. The washing machine may include a drum in which laundry are provided and rotated. A laundry amount may be sensed. The drum may operate at a first speed so that a part of the laundry tumbles within the drum and another part of the laundry adheres to the drum or the drum operates at a second speed so that the laundry adheres to the drum according to the sensed laundry amount. Accordingly, at a time of a dehydration cycle, stability of the washing machine and a laundry balancing can be ensured.

  • Patent number: 7644513
    Abstract: Method for controlling a drying course of a laundry dryer including the steps of (a) starting a drying course by using high temperature drying air, and sensing dryness of a drying object periodically, (b) determining a dryness saturation time point at which the dryness sensed thus exceeds a preset reference value Q, (c) determining a load of the drying object according to the drying saturation time point T_sat, and (d) varying a drying algorithm depending on the load of the drying object determined thus, whereby preventing a small amount of laundry from sticking to a drum in a drying course by varying a control algorithm of the drying motor in a case an amount of the drying object is determined to be small accurately with reference to a saturation time point of an electrode sensor.

  • Publication number: 20090307851
    Abstract: A washing machine and a method of controlling a washing machine are provided. The washing machine may include a drum in which laundry is provided and is rotated. The drum may operate at a first speed such that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum. An unbalance amount or a first speed operation time of the drum, which is detected when the drum operates at the first speed, may be determined. When an abnormality occurs, rotation of the drum may stop or decelerate. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Publication number: 20090300853
    Abstract: The present invention relates to a washing machine and a method of controlling the washing machine. According to a washing machine and a method of controlling the washing machine in accordance with the present invention, a drum operates at a first speed so that part of the laundry tumbles within the drum and another part of the laundry adheres within the drum. The drum operates at a second speed lower than the first speed so that an amount of the tumbling laundry is more increased than at the first speed. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Publication number: 20090300852
    Abstract: The present invention relates to a washing machine and a method of controlling a washing machine. According to the washing machine and the method of controlling the washing machine in accordance with the present invention, the drum is operated at a first speed so that laundry tumbles within the drum. A laundry amount within the drum during the first speed operation is sensed. The drum is driven at a second speed so that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum. Operation commands for driving the drum subsequent to the first speed operation are changed based on the sensed laundry amount. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

    Abstract: The present invention relates to a washing machine and a method of controlling the washing machine. According to the washing machine and the method of controlling the washing machine in accordance with the present invention, the drum is operated at a first speed so that part of laundry tumbles within the drum and another part of the laundry adheres to the drum. When a unbalance amount of the drum operating at the first speed is a first specific value or less, increasing the speed of the drum to a second speed so that the laundry adheres to the drum. When a unbalance amount of the drum detected during increasing to the second speed is a second specific value or more, decelerating the rotation of the drum. Accordingly, at the time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.

  • Patent number: 7526879
    Abstract: A drum washing machine and a clothes dryer equipped with a thermoelectric module are disclosed. The thermoelectric module includes a heat absorption side and a heat dissipation side which absorbs and dissipates heat at a junction between two dissimilar metals depending on direction of current flow through the junction. The heat absorption side is disposed at a hot air flowing passage. Accordingly, the drying apparatus can increase energy efficiency with minor structural modification and becomes environmentally friendly unlike a conventional drying apparatus using a heat pump.
