This threshold value is used to judge whether that the excessive washing agent that surpasses the amount corresponding with the weight of clothing puts in the water receiving tank 2; The CPU of control circuit 59 is under the situation that in water receiving tank 2, has produced the detergent foam that surpasses tolerance before subtraction result value of reaching the limitation of the value of timer T1, and the testing result that is judged as the foam volume signal rises to threshold value above (step S65).That is the amount that, surpasses the tolerance of detergent foam is the too much foam volume that surpasses the suitable foam volume corresponding with the weight of clothing.

The CPU of control circuit 59 rises to threshold value when above (step S65) in the testing result of judging the foam volume signal, makes draining valve 16 switch to open state (step S66) from closed state, begins to discharge the running water in the water receiving tank 2.

Afterwards,, make Rolling motor 3 (step S67) out of service, and set 2 (step S68) in the value of warm water process mark through sending the operation halt instruction to frequency conversion control circuit 62.

The CPU of control circuit 59 does not judge that at step S65 the testing result of foam volume signal is more than the threshold value; And when step S63 is judged as subtraction result value of reaching the limitation (step S63 " being ") of timer T1 value; Make warm water heater 30 switch to starting state (step S69) from closed condition; Thereby begin to heat the running water in the water receiving tank 2, in the value of timer T1, set and be recorded in advance the limit time (7 minutes) (step S70) among the ROM.

This limit time is set to the value that deducts foam Looking Out Time (8 minutes) the longest each foam Looking Out Time table 1～foam Looking Out Time table 4 from wash time (15 minutes); Be set at the CPU of control circuit 59 under the situation of value of timer T1 (step S70), the value of warm water process mark is set 4 (step S71).

Figure 13 is used to explain that the warm water process of the step S47 shown in the flow chart of timer Interrupt Process of control circuit of Figure 11 handles 2.This warm water process is handled 2 values at warm water process mark and is set to and carries out under 2 the situation, is set in the value of warm water process mark under 2 the situation, in water receiving tank 2, discharges running water.

Handle 2 in this warm water process, the value of timer T1 and the value of timer T2 are not carried out subtraction respectively, but under Rolling motor 3 closed conditions, the instrumentation that interrupts wash time is handled.

The CPU of control circuit 59 detects the water level signal (step S81) from level sensor 26, and the testing result of water level signal and the draining end value that is recorded among the ROM are in advance compared (step S82).

This draining end value is the threshold value that is used to judge whether in water receiving tank 2, to have discharged all running water; The CPU of control circuit 59 reaches in the testing result that is judged as water level signal under the situation of draining end value (step S82 " being "), makes draining valve 16 switch to closed state (step S83) from open state.

Afterwards, switch to the water filling state from closed state, begin once more to inject running water (step S84), the value of warm water process mark is set at 3 (step S85) to water receiving tank 2 through making feed water valve 8.

Figure 14 handles 3 in the warm water process of the step S49 shown in the flow chart of the timer Interrupt Process of the control circuit that is used to explain Figure 11.It is that value at warm water process mark is set under 3 the situation and carries out that this warm water process handles 3, is set under 3 the situation injection running water to water receiving tank 2 in the value of warm water process mark.

In this warm water process processing 3, the value of timer T1 and the value of timer T2 are not carried out subtraction, but under Rolling motor 3 closed conditions, interrupt the instrumentation processing of wash time.

The CPU of control circuit 59 detects the water level signal (step S91) from level sensor 26, and the setting result of the water level of the testing result of water level signal and step S10 is compared (step S92).At this; Reach in the testing result that is judged as water level signal under setting result's the situation of water level (step S92 " being "); Through making feed water valve 8 switch to closed state from the water filling state; Thereby stop in water receiving tank 2 injecting running water (step S93), and the operation sign on (step S94) of sending Rolling motors 3 to frequency conversion control circuit 62.

Afterwards, in the value of timer T1, reset the greatest length (step S95) of the selection result of the foam Looking Out Time among the step S31, the value of warm water process mark is set at 1 (step S96).

This frequency conversion control circuit 62 is through receiving the operation sign on of Rolling motor 3, restarts the operation under the washing speed of Rolling motor 3.
