摘要： PROBLEM TO BE SOLVED: To efficiently move washing water between two washing tanks while evading cost increase in a double tank type washing machine. SOLUTION: In this double tank type washing machine, a water passing mechanism capable of passing water between a main washing device 20 and a sub washing device 40 is provided. In the water passing mechanism, a connection water path connected to both washing devices, a valve V2 and a pump P are arranged. The pump P is driven by a motor 44 for diriving the mixing blade 42 of the sub washing device 40 and efficiently moves the washing water. At the time of moving the washing water, after the closed state of a cover 14 covering the upper part of the sub washing device 40 is detected, the motor 44 is driven. Thus, even when the mixing blade 42 is simultaneously rotated, water splashes are prevented. Also, at the time of washing, the valve V2 is closed and the washing water is not moved. The stipulated water level of the washing tank 41 is detected by a water level switch.
