Abstract

PURPOSE: To discharge water without useless time at the time of washing and rinsing by providing a water level detection means inside a washing tub and a control means for inputting the output of the storage means of a plurality of water levels and completing water discharge by prescribed water discharge delay time after a water level discrimination means discriminates a lowest water level in the middle of the water discharge. CONSTITUTION: The water level discrimination means 2 inputs the output of the water level detection means 1 for converting the water level inside the washing tub to an electric signal and the output of the storage means 3 storing high, middle and low water levels and discriminates the water level inside the washing tub as high, middle or low. The control means 5 controls the driving means 6 of a water supply valve and the driving means 7 of a water discharge valve based on the output of a water level setting means 4 for setting the water level inside the washing tub, the water level discrimination means 2 and the storage means 3, transmits the rotation force of a motor by a motor driving means 9 to a pulsator by the changeover of a changeover driving means 8 at the time of a washing process and transmits it to the washing tub at the time of dehydration. At the time of discriminating the low water level at the time of discharging the water after washing, a microcomputer 10 completes the water discharge after the prescribed delay time and shifts to a rinsing process. Rinsing is executed at the high water level after supplying the water in the rinsing process, and at the time of discriminating the low water level, the water discharge is completed after the prescribed delay time.
