Abstract:
PURPOSE:To extract water always in a constant condition regardless of the conditions of the laudry and drainage. CONSTITUTION:A water tank including a washing and hydro-extracting tank wherein a pulsator is rotatably disposed at the center of bottom wall is supported by a suspension rod with a vibro-isolating device. In a washing step, transmission factor of washing water in said tank is detected to determine the kind of detergent to be used. In a hydro-extracting step, a motor is turned on and, after a number of revolution V1 which is lower than the resonance frequency of the tank is attained, the motor is turned off for a specified period (ti) and then turned on again. This operation is repeated (m) times. Next, the motor is turned on and its number of revolution is made higher than the resonance frequency and, after a number of revolution V2 is attained, the motor is turned off for a specified period (tj) and it is turned on again. This operation is repeated (n) times and, thereafter, the motor is turned on continuously to perform hydro-extracting operation. The number of repetitions is changed according to the kind of detergent so that water can be extracted in a constant condition regardless of the detergent.
