Abstract: Disclosed herein is a washing machine with drying function. A heater is mounted in a tub for heating wash water or air in the tub. A circulating channel is connected to the tub for guiding air heated by the heater to the outside of the tub and then supplying the air into a drum such that the laundry in the drum is dried. Consequently, the structure of the washing machine with drying function is simplified, the manufacturing costs of the washing machine with drying function are reduced, and noise generated from the washing machine with drying function is minimized.

Abstract: A spin-dry control method in a washing machine includes sensing a first clothes amount contained in a washing tub, sensing an unbalance of the clothes and a second clothes, after execution of the sensing the first clothes amount, determining a final clothes amount, based on the first clothes amount and the second clothes amount, and executing a main spin-dry process, based on the final clothes amount.

Abstract: A supporting apparatus for a washing machine including a plurality of supporting legs mounted on a base fixed to a lower portion of a washing machine main body to move in the vertical direction, a foot mounted on the lower end of the supporting leg to contact the support surface, and a spring provided between the base and the foot, for applying an elastic force to the foot. The supporting apparatus for the washing machine automatically controls the level of the washing machine by the elastic force of the spring, and reduces noises and vibrations during the operation of the washing machine.

Abstract: In W—Cu alloy having a homogeneous micro-structure and a fabrication method thereof, the method includes forming mixed powders by mixing tungsten powders with W—Cu composite powders; forming a compact by pressurizing-forming the mixed powders; forming a skeleton by sintering the compact; and contacting copper to the skeleton and performing infiltration. W—Cu alloy having a homogeneous structure fabricated by the present invention shows better performance by being used as a material for high voltage electric contact of a contact braker, a material for heat sink of an IC semiconductor and a shaped charge liner.

Abstract: A drying method is performed by a washing machine capable of precisely drying laundry and reducing power consumption, and an apparatus thereof. The method comprises: detecting a decrement of a heating value of a heat generating unit of a washing machine during a drying mode; and cutting off power supplied to the heat generating unit when the detected decrement reaches a preset reference decrement.

Abstract: A method for controlling dewatering of a washing machine includes detecting an initial reference eccentric position of a drum and an initial amount of eccentricity while a drum of a washing machine is rotated at a low speed, detecting a current eccentric position and a current amount of eccentricity of a drum while the drum is rotated at a low speed again after being rotated at a high speed, and controlling dewatering operation based on the detected initial reference eccentric position, the initial amount of eccentricity, the current eccentric position and the current amount of eccentricity.
