KR960014492A - Washing machine according to the amount of washing machine, foam detection device and quantity, quality - Google Patents

Abstract

The present invention relates to a washing amount according to the amount of the washing machine, the foam detection device and the amount, and the quality of the washing machine to prevent damage to the laundry and increase the washing power to perform the optimal washing, according to the present invention The washing blade is rotated forward and backward according to the reverse rotation driving signal. The forward rotation motor driving unit provides the forward rotation driving signal to the motor according to the forward rotation control signal.

The reverse rotation motor driving unit provides the reverse rotation driving signal to the motor according to the input reverse rotation control signal.

The peak current detector detects the peak current level from the motor as data corresponding to the quality of the motor when the motor is rotated for a certain time and in reverse rotation under the condition that only the laundry is supplied to the washing tank without supplying the washing water. When the motor is driven for a predetermined time under the condition that the wash water is supplied, the hall sensor outputs a predetermined number of pulses according to the load amount.

The microcomputer provides forward and reverse rotation control signals under the above-described conditions, determines the quality of the foam based on the maximum current value, and determines the quantity of the fuel according to the number of pulses.
