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

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 ("Yes" of step S63) 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 the pre-recorded limit time (7 minutes) (step S70) in 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 handles 2 for the warm water process of the step S47 shown in the flow chart of the timer interruption processing of the control circuit of explanation Figure 11.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, discharges running water in water receiving tank 2.

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 pre-recorded draining end value in ROM are compared (step S82).

This draining end value is be used to the threshold value that judges whether to have discharged all running water in water receiving tank 2, 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 ("Yes" of step S82), makes draining valve 16 switch to closed state (step S83) from open state.

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

Figure 14 handles 3 in the warm water process of the step S49 shown in the flow chart of the timer interruption processing of the control circuit that is used for explanation 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 in the value of warm water process mark under 3 the situation, injects running water in water receiving tank 2.

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 ("Yes" of step S92), by 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 send the operation sign on (step S94) of Rolling motor 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 by receiving the operation sign on of Rolling motor 3, restarts the operation under the washing speed of Rolling motor 3.

The CPU of control circuit 59 is when having set 1 (step S96) in the value of warm water process mark, handle 1 in each warm water process of carrying out Figure 12 when timer interrupts handling that starts, warm water process at Figure 12 handles 1, be that a reference value is carried out subtraction to the value of timer T1 with the setting result again of foam Looking Out Time, and be that a reference value is carried out subtraction to the value of timer T2 with the value in the moment of the operation of having interrupted Rolling motor 3.

Handle 1 in this warm water process, under the testing result of foam volume signal before the subtraction result value of reaching the limitation that is judged as in the value of timer T1 rises to situation more than the threshold value, in water receiving tank 2, discharge running water again, stop the operation of Rolling motor 3, the value of warm water process mark is set at 2.

Handling 1 testing result that is not judged as the foam volume signal in this warm water process rises to more than the threshold value, but be judged as under the situation of the subtraction result value of reaching the limitation of value of timer T1, making warm water heater 30 switch to starting state from closed condition begins the heating of the running water in the water receiving tank 2, and in the value of timer T1, set the limit time, the value of warm water process mark is set at 4.

Figure 15 handles 4 in the warm water process of the step S51 shown in the flow chart of the timer interruption processing of the control circuit that is used for explanation Figure 11.This warm water process is handled 4 values at warm water process mark and is set under 4 the situation and carries out, in water receiving tank 2, do not produce excessive foam and passed through under the situation of greatest length of selection result of foam Looking Out Time, in the value of warm water process mark, set 4.

The CPU of control circuit 59 deducts certain value (1sec) (step S101) from the value of timer T1, and, deduct certain value (1sec) (step S102) from the value of timer T2, detect the water temperature signal (step S103) from cooling-water temperature sensor 14.

The testing result of this water temperature signal is that the CPU of control circuit 59 is detecting under the situation of water temperature signal with the running water temperature after 30 heating of warm water heater, judges subtraction result value of reaching the limitation 0 (step S104) whether of the value of timer T1.At this, under the situation of subtraction result value of reaching the limitation 0 of the value that is judged as timer T1 ("Yes" of step S104), close warm water heater 32 (step S106).

The CPU of control circuit 59 is in the subtraction result of the value that is judged as timer T1 not ("No" of step S104) during the value of reaching the limitation, and testing result and the limit temperature that is predetermined in ROM of water temperature signal compared (step S105).

At this, under the testing result that is judged as water temperature signal reaches the limitation the situation of temperature ("Yes" of step S105), close warm water heater 30 (step S106), transfer to step S107.

Namely, after carrying out washing treatment intermediate roll motor 3 brings into operation, also do not generate under the situation of excessive foam even passed through the greatest length of the selection result of foam Looking Out Time, warm water heater 30 is that benchmark is activated with the greatest length of the selection result of process foam Looking Out Time.

Under the situation that warm water heater 30 is activated, be that benchmark has passed through under the situation of limit time in the startup with warm water heater 30, or reach the limitation under the situation of temperature from the water temperature signal of cooling-water temperature sensor 14 that warm water heater 30 is closed.

According to above-described embodiment 1, has following effect.

Be set at the warm water washing mode under the situation of starting state, under the closed condition of warm water heater 30, begin carrying out washing treatment, do not surpass the detergent foam of holding sales volume and be judged as through under the situation of foam Looking Out Time being judged as in water receiving tank 2, to have produced, make warm water heater 30 switch to starting state from closed condition, and begin the running water that contain washing agent in the water receiving tank 2 are heated.

Be judged as through before the foam Looking Out Time, be judged as under the situation that in water receiving tank 2, has produced the detergent foam that surpasses tolerance, discharging the running water before the heating that contains washing agent in the water receiving tank 2.

That is, determining that in the water receiving tank 2 discharge contains under the situation of running water of washing agent, making warm water heater 30 switch to starting state from closed condition.

Do not determine in water receiving tank 2, not discharge under the situation of the running water that contains washing agent having, do not make warm water heater 32 switch to starting state from closed condition, so can avoid in the energy waste that will the running water warm waterization in the water receiving tank 2 be discharged from afterwards.

Owing to select a foam Looking Out Time corresponding with the testing result of cloth amount from foam Looking Out Time table 1, even so surpass the time required till the tolerance according to what and change of the cloth amount cylinder 4 in from water receiving tank 2, beginning to generate foam to the foam growing amount, also can be enough set the foam Looking Out Time with the how much value of corresponding weak point of the interior cloth amount of cylinder 4.

In addition, owing to select a foam Looking Out Time corresponding with the testing result of cloth matter from foam Looking Out Time table 2, even so surpass the time required till the tolerance according to what and change of the composite rate of the chemical fibre of the clothing cylinder 4 in from water receiving tank 2, beginning to generate foam to the foam growing amount, also can be enough set the foam Looking Out Time with the how much value of corresponding weak point of the composite rate of chemical fibre.

And, owing to select a foam Looking Out Time corresponding with the setting result of working procedure from foam Looking Out Time table 3, even so surpass the time required till the tolerance according to the power of the mixing power of 4 pairs of water of cylinder and change from water receiving tank 2, beginning to generate foam to the foam growing amount, also can be enough set the foam Looking Out Time with the value of the strong and weak corresponding weak point of mixing power.

In addition, owing to select a foam Looking Out Time corresponding with the testing result of water temperature from foam Looking Out Time table 4, even so surpass the height of the water temperature of time required till the tolerance before according to heating and change from water receiving tank 2, beginning to generate foam to the foam growing amount, also can set the foam Looking Out Time with the value of the weak point of the height correspondence of water temperature.

Left front teat 33 and right front teat 34 are set in the heater container 31 of warm air heating device 25.

Therefore, when ptc heater 32 in heater container 31 from after forward the biasing situation under, the left front baffle plate 51 of ptc heater 32 is contacted with the left front teat 33 of heater container 31, in addition, the right front baffle plate 51 of ptc heater 32 is contacted with the right front teat 34 of heater container 31, ptc heater 32 in heater container 31, keep from after forward the biasing state.

Keep under the state of ptc heater 32 at these left front teats 33 and right front teat 34, the rear surface of the header board of the front end face of left heating element heater 39 and heater container 31 forms the gap each other.

Therefore, even having the place to go, the detergent foam that is full of in water receiving tank 2 in carrying out washing treatment is not attached to by fan drum 20 and water back 21 under the situation of rear surface of header board of heater container 31 from the entrance of dehumidifying pipeline 18, the mutual leaky of left battery lead plate 41 and common electrode plate 42 also be difficult to take place, the mutual leaky of left battery lead plate 41 and right battery lead plate 44 be difficult to take place, and is difficult to take place the mutual leaky of common electrode plate 42 and right battery lead plate 44.

[embodiment 2]

Then, with reference to Figure 16～Figure 18, embodiment 2 is described.CPU by control circuit 59 carries out the carrying out washing treatment of Figure 16 to replace the carrying out washing treatment of the Figure 10 among the embodiment 1.

The CPU of control circuit 59 is being judged as under the situation that warm water washing flag settings is starting state ("Yes" of step S21), EEPROM according to control circuit 59 detects foam Looking Out Time (step S38), and sets the testing result (step S32) of foam Looking Out Time in the value of timer T1.

This EEPROM is used for pre-recorded foam Looking Out Time, and pre-recorded in EEPROM have 5 minutes, as the initial value of foam Looking Out Time.

The CPU of control circuit 59 is when being set at starting state with Rolling motor 3 (step S35), and whether the value of judging timer T2 value of reaching the limitation 0 (step S36).

At this, in the value that is judged as timer T2 not ("No" of step S36) under the situation of the value of reaching the limitation, transfer to the change of foam Looking Out Time and handle (step S160).

The CPU of control circuit 59 carries out the warm water process processing 1 of Figure 17 and handles 1 with the warm water process of Figure 12 of replacement embodiment 1.

The CPU of control circuit 59 is under the situation of subtraction result value of reaching the limitation 0 of the value that is judged as timer T1 ("Yes" of step S63), pass through step S69～S71 respectively, the foam Looking Out Time of RAM is set at starting state (step S72) through mark (Flag).

This foam Looking Out Time represents whether passed through the foam Looking Out Time, S1 is initially set closed condition in step through mark, and under the situation that carrying out washing treatment finishes, the Rolling motor 3 of Figure 16 is set to closed condition being closed (step S37) afterwards.

Figure 18 is that the foam Looking Out Time upgrades processing (step S160), and the CPU of control circuit 59 judges that the foam Looking Out Time is through marking whether to be set to starting state (step S161).

For example, in the carrying out washing treatment after foam Looking Out Time process, being judged as the foam Looking Out Time is starting state ("Yes" of step S161) through flag settings, and judges whether the foam Looking Out Time update mark of RAM is set to closed condition (step S162).

This foam Looking Out Time update mark represents whether the foam Looking Out Time of EEPROM is updated, S1 is initially set closed condition in step, under the situation that carrying out washing treatment finishes, be closed (step S37) afterwards at the Rolling motor 3 of Figure 16, be set to closed condition.

The CPU of control circuit 59 is being judged as the update mark of foam Looking Out Time when being set to closed condition ("Yes" of step S162), detection is from the foam volume signal (step S163) of foam volume sensor 28, and testing result and the threshold value of foam volume signal compared (step S164).

This threshold value is identical with the threshold value of using in the step S65 of Figure 17, the CPU of control circuit 59 rises to threshold value when above ("Yes" of step S164) in the testing result that is judged as the foam volume signal, foam Looking Out Time at EEPROM adds pre-recorded certain value (2 minutes) (step S165) in ROM, and the update mark of foam Looking Out Time is set at starting state (step S166).

That is, when time carrying out washing treatment in not have to generate under the situation of the foam Looking Out Time that has passed through EEPROM above the detergent foam of tolerance, warm water heater 25 switches to starting state from closed condition.

Generated under the situation of the detergent foam that surpasses tolerance at the starting state of this warm water heater 25, the foam Looking Out Time of EEPROM is prolonged certain value (2 minutes), in the carrying out washing treatment of next time, detect new foam Looking Out Time after prolonging from EEPROM.

According to above-described embodiment 2, has following effect.

Be judged as through in water receiving tank 2, having produced after the foam Looking Out Time under the situation of the detergent foam that surpasses tolerance, foam Looking Out Time at EEPROM adds that certain value (2 minutes) prolongs the foam Looking Out Time of EEPROM afterwards, even so the difference of the kind of hardness of water and washing agent etc. from the beginning and make the generation speed difference of detergent foam, the foam Looking Out Time also is set to the suitable value corresponding with the speed that generates foam in the carrying out washing treatment of reality.

That is, the foam Looking Out Time of EEPROM is initially set the shortest value, prolongs by the generation state according to the foam of reality, can change to the suitable value corresponding with the generation state of the foam of reality.

[embodiment 3]

The carrying out washing treatment of Figure 19 is the processing that the CPU of control circuit 59 replaces the carrying out washing treatment of Figure 10 to carry out, the CPU of control circuit 59 sets wash time (15 minutes) (step S121) in the value of timer T2, to frequency conversion control circuit 62 the operation sign on takes place and make Rolling motor 3 beginnings with washing speed operation (step S122).

Afterwards, start warm water heater 30 (step S123), value and the limit value 0 of timer T2 compared (step S124).The value of this timer T2 is carried out subtraction in the timer of Figure 20 interrupts handling.

The CPU of control circuit 59 is ("Yes" of step S124) under the situation that is judged as the value value of reaching the limitation 0 that reaches timer T2, marks whether to be set to closed condition (step S125) during the cylinder of judgement RAM stops.

Mark was illustrated in carrying out washing treatment intermediate roll motor 3 and whether has stopped operation during this cylinder stopped, and S1 is initially set closed condition in step.

The CPU of control circuit 59 be judged as cylinder stop in mark be set under the situation of closed condition ("Yes" of step S125), to frequency conversion control circuit 62 the operation halt instructions taking place, and makes Rolling motor 3 (step S126) out of service.

Be judged as cylinder stop in mark be set under the situation of starting state ("No" of step S125), cylinder is stopped middle mark be set at closed condition (step S127), judge all that under any circumstance the warm water washing marks whether to be set to starting state (step S128).

At this, be set under the situation of starting state ("Yes" of step S128) being judged as warm water washing mark, close warm water heater 30 (step S129), it is closed condition (step S130) that warm water is washed flag settings.

The timer interruption processing of Figure 20 is that the CPU of control circuit 59 replaces the timer of Figure 11 to interrupt handling the processing of carrying out, and the CPU of control circuit 59 judges that whether the value of timer T2 is greater than limit value 0 (step S141).

At this, under the situation of the value that is judged as timer T2 greater than limit value 0 ("Yes" of step S141), deduct certain value (1sec) (step S142) from the value of timer T2.

Then, the CPU of control circuit 59 judges that the warm water washing marks whether to be set to starting state (step S143).At this, be set under the situation of starting state ("Yes" of step S143) being judged as warm water washing mark, judge that cylinder marks whether to be set to closed condition (step S144) in stopping.

At this, be judged as cylinder stop in mark be set under the situation of closed condition ("Yes" of step S144), detection is from the foam volume signal (step S145) of foam volume sensor 28, and testing result and the threshold value of foam volume signal compared (step S146).

When the testing result that is judged as the foam volume signal as the CPU of control circuit 59 does not reach threshold value ("No" of step S146), detection is from the water temperature signal (step S147) of cooling-water temperature sensor 14, and testing result and the limit temperature of water temperature signal compared (step S148).

At this, under the testing result that is judged as water temperature signal reaches the limitation the situation that temperature judges ("Yes" of step S148), close warm water heater 30 (step S149), it is closed condition (step S150) that warm water is washed flag settings, and mark was set at closed condition (step S151) during cylinder was stopped.

Namely, warm water heater 30 brings into operation with Rolling motor 3 in carrying out washing treatment and is activated as benchmark, in carrying out washing treatment, do not have generate to surpass tolerance amount foam and running water in the water receiving tank 2 is warmed up under the situation of limit temperature, warm water heater 30 is closed.

Under these warm water heater 30 pent situations, under the starting state of the closed condition of warm water heater 30 and Rolling motor 3, carrying out washing treatment lasts till through till the wash time.

When the CPU of control circuit 59 reaches threshold value in the testing result that is judged as the foam volume signal ("Yes" of step S146), send the operation halt instruction to frequency conversion control circuit 62 and make Rolling motor 3 (step S152) out of service, mark was set at starting state (step S153) during cylinder was stopped.

In this cylinder stops under the starting state of mark, transfer to step S147 from the step S144 that illustrates previously, detection is from the water temperature signal (step S147) of cooling-water temperature sensor 14, and testing result and the limit temperature of water temperature signal compared (step S148).

This limit temperature is equivalent to heat stop condition, the CPU of control circuit 59 is under the testing result that is judged as water temperature signal reaches the limitation the situation that temperature judges ("Yes" of step S148), close warm water heater 30 (step S149), it is closed condition (step S150) that warm water is washed flag settings, and with cylinder stop in mark be set at closed condition (step S151).

That is, the running water in carrying out washing treatment in the water receiving tank 2 is warmed up under the situation that has produced the foam that surpasses tolerance before the limit temperature, and Rolling motor 3 is closed, and continues carrying out washing treatment under the starting state of the closed condition of Rolling motor 3 and warm water heater 30.

Running water in water receiving tank 2 is warmed up under the situation of limit temperature, this warm water heater 30 is closed, under warm water heater 30 pent situations, under Rolling motor 3 and warm water heater 30 difference closing state, up to continuing carrying out washing treatment through till the wash time.

According to above-described embodiment 3, has following effect.

Be set at the warm water washing mode under the situation of starting state, under the starting state of warm water heater 30, begin carrying out washing treatment, before the testing result that is judged as water temperature signal reaches the limitation temperature, be judged as under the situation that in water receiving tank 2, has produced the detergent foam that surpasses tolerance, Rolling motor 3 is switched to closed condition from starting state.

Therefore, when can the detergent foam in suppressing water receiving tank 2 growing up under the mixing power of cylinder 4, the continuation carrying out washing treatment is so avoid the energy waste that causes of discharging after the water in the water receiving tank 2 carry out warm waterization.
