Document Type and Number:
Japanese Patent JP5129949
Kind Code:
B2
Abstract:
To provide an inexpensive and secure detection means for detecting abnormal occurrence of bubbles during washing caused by the excessive charge of a detergent.
The washing machine includes: a pair of electrodes (C1, C2); a transformer (T) connected with the electrodes; bubble detection means (R3, C, OP1) electrically insulated by the transformer (T) for converting the resistance change between electrodes to oscillation frequency change and outputting it; and a control means for controlling a series of washing operations. When detecting the bubbles, the control means controls water supply and water discharge.
