Control device 150 controls circulating pump 90 during water supply in SP.SP includes first period SP1, second during water supply SP3 during period SP2 and third (referring to Fig. 8).First period SP1 is during circulating pump 90 drives.The second phase, SP2 was After first period SP1 circulating pump 90 stop or after first period SP1 circulating pump 90 than in first period SP1 During the weak drive force of driving force.In addition, second phase SP2 includes the water level arrival water level WL in inside groove 30 Time point.

In first period SP1, with the driving of circulating pump 90, it is formed in outer groove 20, inside groove 30 and circulating path 70 The flowing of the water of middle circulation generates foam in outer groove 20 and inside groove 30.The case where second phase SP2 internal circulation pump 90 stops Under, water is without circulation in the path including circulating path 70, therefore foam is generated in outer groove 20 and inside groove 30 Power dies down.In the case where second phase SP2 internal circulation pump 90 is with weak drive force, the flowing of the water recycled it is strong Degree dies down, therefore the foam not easily generated in outer groove 20 and inside groove 30.In this way, in the outer groove 20 compared with first period SP1 and interior The state of foam not easily generated is formed in the second phase SP2 that water level in slot 30 is got higher, therefore can reduce foam from outer groove 20 risks overflowed.In addition, circulating pump 90, which is in, to be stopped at the highest water level WL of water level in outer groove 20 and inside groove 30 Or circulating pump 90 is with weak drive force, therefore can further decrease the risk that foam is overflowed from outer groove 20.In an example In, second phase SP2 is during circulating pump 90 after first period SP1 stops.

The problem of overflowing foam from outer groove occurs mainly in the washing machine including circulating path.

The washing machine (hereinafter referred to as " the first washing machine ") of first case does not include outer capping and dry path.In the first laundry Think in the case where machine: foam is deposited in the water surface in outer groove and inside groove in the case where generating a large amount of foam in inside groove On, and foam is overflowed via the second opening of outer groove.

The washing machine (hereinafter referred to as " the second washing machine ") of second case includes outer capping without including dry path.Second washes The outer capping of clothing machine is not used to the clothing in inside groove be shut up and made using drying machine the purposes of the cloth drying, therefore Need to discharge the vapor generated from clothing, therefore using outer capping that the second opening of outer groove is suitably not close in most cases Close or be formed in outer capping slit.It is therefore contemplated that in the case where generating a large amount of foam in inside groove, foam accumulation On the water surface in outer groove and inside groove, foam overflows via the slit in gap or outer capping between the shell and outer capping of outer groove Out.

The washing machine (hereinafter referred to as " third washing machine ") of third example includes outer capping and dry path.Third washing machine An example is the washing machine of drum-type.Think in the case where third washing machine: the case where generating a large amount of foam in inside groove Under, foam is deposited on the water surface in outer groove and inside groove, which further overflows from outer groove and enter in dry path.At this In the case of, it is possible to be attached to drying machine into the foam in dry path.

4th washing machine is washing machine 1 shown in FIG. 1.Washing machine 1 is possible to generate same as third washing machine Problem.In addition, in washing machine 1, in the case where generating a large amount of foam in inside groove 30, foam is deposited in outer groove 20 and interior On the water surface in slot 30, foam is further also deposited in detergent box 40.In this case, it is believed that the bubble overflowed from outer groove 20 Foam is overflowed from the gap being formed between detergent box 40 and the lid of the detergent box 40.

SP3 is the stopping of circulating pump 90 or the circulating pump before first period SP1 before first period SP1 during third During 90 with the drive force weaker than the driving force in first period SP1.It is low with the water level in inside groove 30 in outer groove 20 Under state, the amount of outer groove 20 and the water in inside groove 30 is few, therefore is not easy to efficiently generate foam.In washing machine 1, in outer groove 20 In the state of low with the water level in inside groove 30, circulating pump 90 stops, or even if it drives in the case where circulating pump 90 drives Power is also weak, therefore can be improved the service efficiency of the energy in washing machine 1.

SP3 includes starting from watering supplies water into outer groove 20 until being filled with water in circulating pump 90 during third During.In one example, control device 150 controls circulating pump 90 during third in SP3, so that circulating pump 90 stops.Therefore, It can reduce the risk that the operating of pump 90 is started the cycle in the state that circulating pump 90 includes air.

150 control loop of control device pump 90, so that second phase SP2 is than SP3 long during third.Due in first period The second phase SP2 of foam not easily generated or few second phase SP2 generating its production quantity of foam become after SP1 It is long, therefore the risk that foam is overflowed from outer groove 20 can be further decreased.Such as it is fitted according to the laundry amounts accommodated in inside groove 30 The length of SP3 during change first period SP1, second phase SP2 and third.

150 control loop of control device pump 90, so that making circulating pump 90 that driving be repeated and stop in first period SP1 Circulating pump 90 only or in first period SP1 is set to be in the weak state of driving force strong state and driving force repeatedly.In order to Generate foam and with strongly constantly stir water in the case where, the volume of foam is possible to sharp increase.In washing machine 1, In order to generate foam in first period SP1 that circulating pump 90 is driven, the driving for intermittently forming circulating pump 90 stops The weak state of the driving force of state or circulating pump 90 only, therefore can reduce the risk that foam is overflowed from outer groove 20.In an example In, in the case that the amount of the clothing accommodated in inside groove 30 is more than specified amount, 150 control loop of control device pump 90, so that Make circulating pump 90 that driving and stopping be repeated in first period SP1.Based on make impeller 110 rotate when act on washer motor Whether 121 amount for loading to determine the clothing of the interior receiving of inside groove 30 is more than specified amount.

Control device 150 during water supply drives in SP driving portion 120, thus controls the movement of impeller 110.Pass through confession The driving of circulating pump 90 during water in SP in outer groove 20 and inside groove 30 generates foam, by impeller 110 rotated come Stir the water in inside groove 30.Therefore, being unevenly distributed for foam generated in outer groove 20 and inside groove 30 becomes smaller, each in inside groove 30 The removal of the dirt of clothing is not likely to produce unevenly.

Control device 150 drives driving portion 120 in the state of driving circulating pump 90 in SP during water supply.Due to It ordinatedly forms the state for recycling water using circulating pump 90 and stirs the state of water by the rotation of impeller 110, because This is able to efficiently generate foam.Control device 150 starts the cycle over pump 90 and drives after putting at the beginning of SP during water supply The driving in dynamic portion 120.In one example, control device 150 maintains the state for stopping driving portion 120 during third in SP3, Start the driving of driving portion 120 in first period SP1.Circulating pump 90 and driving portion in the state that water level in inside groove 30 is low 120 do not drive, therefore can reduce following risk: clothing contacted with the impeller 110 that the driving by driving portion 120 rotates and Damage.

Control device 150 makes circulating pump 90 and driving portion 120 stop driving during water supply in the way of SP.In one example, Control device 150 makes driving portion 120 stop driving in second phase SP2.Stop in the driving of circulating pump 90 and driving portion 120 In the case where, water does not recycle, therefore the foam not easily generated in outer groove 20 and inside groove 30.Therefore, it can reduce foam from outer groove 20 risks overflowed.

Control device 150 controls driving portion 120, so that from making driving portion 120 stop driving in the way of SP during water supply Time light until supply water during SP end time point until during length ratio make driving portion in SP during water supply Length during 120 drivings is long.In one example, control device 150 controls driving portion 120, so that the second phase, SP2 was than first It is long during driving driving portion 120 in period SP1.Therefore, the risk that foam is overflowed from outer groove 20 can be further decreased.

Control device 150 controls driving portion 120, so that the output of the driving portion 120 during supplying water in SP was compared in delivery period Between driving portion 120 in the case that driving portion 120 is driven after SP output it is small.In one example, the control of control device 150 is driven Dynamic portion 120, so that the output of the driving portion 120 during supplying water in SP is smaller than the output of the driving portion 120 during washing in WP.? During the low water supply of water level during the washing compared with WP in inside groove 30 in SP, the output of driving portion 120 is small, therefore is able to suppress Clothing is contacted with impeller 110 and is damaged.

Control device 150 controls driving portion 120, so that the maximum (top) speed ratio of the driving portion 120 during supplying water in SP is supplying The maximum (top) speed of driving portion 120 in the case that driving portion 120 is driven after SP during water is low.In one example, control dress 150 control driving portions 120 are set, so that the maximum (top) speed of the driving portion 120 during supplying water in SP is than the driving during washing in WP The maximum (top) speed in portion 120 is low.The revolving speed of driving portion 120 and the revolving speed of impeller 110 have correlation.Therefore, even if with driving The driving in portion 120 makes impeller 110 and contact with clothing, also due to the revolving speed of impeller 110 is low and is less prone to damaging laundry.Control dress 150 control driving portions 120 are set, so that driving portion 120 continuously drives in WP for example during washing.

It is illustrated referring to an example of Fig. 7 to the movement of the circulating pump 90 in WP during the washings of various washing procedures.Fig. 7 Bracket shown in numerical value indicate circulating pump 90 drive time or stopping time.The unit of time is the second.

The control loop pump 90 in various washing procedures of control device 150, so that including making to recycle in WP during washing The state of 90 driving of pump and the state for stopping circulating pump 90.In the case that WP internal circulation pump 90 drives during washing, formed The flowing of the water recycled in outer groove 20, inside groove 30 and circulating path 70 generates foam in outer groove 20 and inside groove 30.It is washing In the case where washing the stopping of period WP internal circulation pump 90, do not recycled in the path Zhong Shui including circulating path 70, therefore outside The power that foam is generated in slot 20 and inside groove 30 dies down.In this way, the state of foam not easily generated is formed in WP during washing, therefore It can reduce the risk that foam is overflowed from outer groove 20.

Control device 150 controls circulating pump 90 during the washing of various washing procedures in WP, so that circulating pump 90 drives During than circulating pump 90 stop during it is long.Therefore, the foam of the amount suitable for washing is easily generated in WP during washing.Control Device 150 processed makes circulating pump 90 during the second half section of the end time point of WP during including washing in various washing procedures Stop.During substantially washing off the washing of dirt of clothing during the second half section of WP, the production quantity of foam is complete to the washing of clothing It is small at influence caused by situation.Therefore, it by stopping circulating pump 90 during the second half section of WP during washing, is able to suppress pair The washing performance of clothing impacts, and can reduce the risk that foam is overflowed from outer groove 20.

WP2 during the washing of WP1 and second during WP includes the first washing during washing (referring to Fig. 8).During first washing WP1 be driving portion 120 output phase to height during.WP2 is the output phase of driving portion 120 to the low phase during second washing Between.150 control loop of control device pump 90 so that during the first washing include in WP1 circulating pump 90 drive state, the The state stopped in WP2 including circulating pump 90 during two washings.During the first high washing of the output of driving portion 120 in WP1 Circulating pump 90 is driven, and thus the production quantity of foam becomes more.Therefore, the power for washing off the dirt of clothing becomes strong.It is driving WP2 internal circulation pump 90 stops during the second low washing of the output in portion 120, and thus the production quantity of foam becomes less.Therefore, energy Enough reduce the risk that foam is overflowed from outer groove 20.

Control device 150 controls driving portion 120, so that the maximum (top) speed ratio of the driving portion 120 during the second washing in WP2 The maximum (top) speed of driving portion 120 during first washing in WP1 is low.Therefore, the production quantity of the foam during the second washing in WP2 It is further reduced, the risk that foam is overflowed from outer groove 20 can be further decreased.Control device 150 controls driving portion 120, so that The end time point of WP during including washing in WP2 during the second washing.Therefore, in the end time including WP during washing Driving portion 120 is driven in WP2 with low output during second washing of point, and thus, it is possible to inhibit the washing to clothing to complete Situation impacts, and can reduce the risk that foam is overflowed from outer groove 20.In one example, control device 150 is washed second It washs and controls driving portion 120 in period WP2, so that the multiple clothings separation accommodated in inside groove 30.

150 control loop of control device pump 90, so that the state driven in WP1 including circulating pump 90 during the first washing With the state of stopping.In one example, the end time dot cycle pump 90 of WP1 stops during the first washing.With circulating pump 90 The time continuously driven is elongated, and the volume of the foam on the water surface in inside groove 30 becomes more, the possibility that foam is overflowed from outer groove 20 Property is got higher.The case where WP1 internal circulation pump 90 drives continuously for a long time during the first high washing of the output of driving portion 120 Under, which further gets higher.In washing machine 1, include in WP1 during the first high washing of the output of driving portion 120 State circulating pump 90 driving and stopped, therefore can be avoided the case where circulating pump 90 drives continuously for a long time, to reduce The risk that foam is overflowed from outer groove 20.

Multiple washing procedures include long-time program and short time program.WP is relatively long during long-time program is washing Washing procedure.Long-time program is for example including the first washing procedure, the second washing procedure and third washing procedure.Long-time journey WP is successively elongated by the sequence of the first washing procedure, the second washing procedure and third washing procedure during the washing of sequence.In short-term Between program be washing during the relatively short washing procedure of WP.Short time program is for example including the 4th washing procedure, the 5th washing journey Sequence, the 6th washing procedure, the 7th washing procedure and the 8th washing procedure.WP is by the 4th washing during the washing of short time program Program, the 5th washing procedure, the 6th washing procedure, the sequence of the 7th washing procedure and the 8th washing procedure are successively elongated.? WP internal circulation pump 90 does not drive during the washing of 8th washing procedure.
