Disclosed is a method for controlling a drum-type washing machine including the steps of (a) switching on a water supply valve and switching on a circulation pump and a heater, (b) switching off the water supply valve after the switching-on of the water supply valve, and (c) switching off the circulation pump and the heater after the switching-off of the water supply valve. The method allows laundry to be effectively cleaned using a small quantity of the wash water and minimizes a power consumption rate required to operate the heater through several repetitions of the steps (a) to (c).

Disclosed is a method for precisely sensing an amount of laundry of a washing machine without influence of static friction. The method includes the steps of (a) operating a motor, and then carrying out regenerative braking of the motor, (b) re-operating the motor after the step (a), and then carrying out rheostatic braking of the motor, and (c) determining the amount of laundry by means of the principle of the conservation of energy in the regenerative braking of the motor in the step (a) and the principle of the conservation of energy in the rheostatic braking of the motor in the step (b).

A clothes amount sensing method in a washing machine which is capable of reducing clothes amount sensing errors caused by frictional forces, thereby achieving an enhancement in accuracy and reliability. The method includes an acceleration step for accelerating, to a predetermined RPM, a motor adapted to rotate the wash tub, a constant-speed step for maintaining the motor at the predetermined RPM when an RPM of the motor reaches the predetermined RPM in accordance with the acceleration step, a deceleration step for turning off the motor to decelerate the motor, following the constant-speed step, and a clothes amount determination step for determining the amount of the clothes by use of equations of motion respectively established in the acceleration, constant-speed, and deceleration steps.

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.

Disclosed herein is a clutch device for washing machines. The clutch device comprises a washing shaft for transmitting a rotating force to a pulsator, a dewatering shaft disposed along the outer circumference of the washing shaft in a coaxial fashion for transmitting the rotating force to a washing tub, and a spiral spring, having one end fixedly connected to the washing shaft and the other end fixedly connected to the dewatering shaft, for transmitting the rotating force from the washing shaft to the dewatering shaft when the spiral spring comes into tight contact with the washing shaft or the dewatering shaft as the washing shaft is rotated. Consequently, the present invention has the effect of simplifying the overall structure of the clutch device. The clutch device further comprises a friction member attached to the washing shaft or the dewatering shaft for generating a frictional force when the spiral spring is extended or compressed. Consequently, the present invention has the effect of decreasing wear of the washing shaft and dewatering shaft, with which the spiral spring is in tight contact, and of improving efficiency of rotating force transmission.
摘要:
A washing machine having a drying function and a method for controlling the same. The washing machine includes a tub for containing wash water; a drum rotatably placed in the tub for containing laundry, and provided with through holes for circulating the wash water or air therethrough; a drying device provided with a circulation fan and a heater for drying the laundry in the drum; and a pumping device for pumping the wash water in the tub so that the wash water in the tub is circulated into the drum or heated by the air passing through the drying device, and is then circulated into the drum. The washing machine performs washing of laundry without any additional heater for heating the wash water, thereby having low production costs and a simple structure of the tub.
