In some embodiments of the invention, control method realizes by step S106 to step S114.
Step S106: judge whether to receive the user operation instruction starting described filter assemblies cleaning procedure.Step S108 is performed when judged result is "No".
Step S108: after continuing to judge to send alerting signal first, whether the number of times performing water purification program for washing reaches pre-determined number.Step S110 is performed when judged result is "Yes".
Step S110: forbid again performing water purification program for washing.After step silo, can return in step S106, continue to judge whether to receive the user operation instruction starting described filter assemblies cleaning procedure.
If the judged result of step S108 is "No", namely after sending alerting signal first, the number of times performing water purification program for washing does not reach pre-determined number, then perform step S114: the accumulative number of times performing water purification program for washing after sending vision and/or audible signal first.Then return in step S106, continue to judge whether to receive the user operation instruction starting described filter assemblies cleaning procedure.
If the judged result of step S106 is "Yes", namely receive the user operation instruction starting described filter assemblies cleaning procedure, then perform step S112, described filter assemblies is cleaned, and the enable water purification of execution again program for washing.Then, return in step S102, again judge whether to need to clean described filter assemblies according to pre-set programs.
In other alternate embodiment, also can perform step S106 and step S108 simultaneously, namely after judging to send alerting signal first, whether the number of times performing water purification program for washing reaches pre-determined number simultaneously, and judges whether to receive the user operation instruction starting filter assemblies cleaning procedure.If judged result be " do not receive the user operation instruction starting filter assemblies cleaning procedure; and the number of times performing water purification program for washing reaches pre-determined number ", then perform step S110, forbid again performing water purification program for washing, return step S106, until receive clear instruction, perform step S112, the enable water purification of execution again program for washing.Then, return in step S102, again judge whether to need to clean described filter assemblies according to pre-set programs.
If performing the judged result of step S106 and step S108 be " the user operation instruction (whether the number of times no matter performing water purification program for washing reaches the judged result of pre-determined number) receiving startup filter assemblies cleaning procedure " simultaneously, then perform step S112, enable execution water purification program for washing.Then, return in step S102, again judge whether to need to clean described filter assemblies according to pre-set programs.
In certain embodiments, the product discharge that aforementioned pre-set programs can comprise according to measuring filter assemblies judges that described filter assemblies is the need of cleaning.Particularly, as shown in Figure 2, described pre-set programs can comprise step S212 further to step S216.
Step S202: perform water purification program for washing.By put into washing machine until washing clothes cylindric washer after, after washing machine receives the instruction of water purification laundry operations, perform water purification program for washing.In step S112, when operating circulating water filtration stage, the water in cylindric washer is pumped into filter assemblies by washing machine, and after being filtered in filter assemblies, recirculation flow returns in cylindric washer.
Step S204: the product discharge measuring described filter assemblies after recirculated water filtration stage runs.
Producing discharge comparatively accurately to obtain, after recirculated water filtration stage runs a Preset Time, preferably measuring the product discharge of described filter assemblies.In a further embodiment, Preset Time can be set to 10 seconds to 2 minutes; Be more preferably 20 seconds to 1 minute.
Step S206: judge whether the product discharge measured is less than default flow threshold.If perform step S210; If not, step S208 is performed.
Here flow threshold can be set to 25-50 l/h; Be more preferably 30 ls/h.The traffic requirement of the water circulation after filtering in washing machine can be met like this when the product discharge of filter assemblies is more than or equal to flow threshold.
Step S208: flow transfinite cumulative number reset and again add up.
Step S210: the cumulative number that transfinited by the flow of washing machine adds 1.
In embodiments of the present invention, when the product discharge of filter assemblies is less than default flow threshold, show that the pollution of filter assemblies is comparatively serious.Therefore, when can be less than default flow threshold in the product discharge measured, judge to need to clean filter assemblies.
In a further embodiment, the washing machine of the embodiment of the present invention can comprise the air pump for carrying out air purge to filter assemblies, described water purification program for washing also can comprise filter assemblies air purge and water rinses after recirculated water filtration stage, for carrying out one or many air purge and water washing operations to filter assemblies.Wherein air purge and water washing operations comprise and utilize air-flow to carry out air purge and utilize current to wash filter assemblies to filter assemblies successively.For the washing machine of these embodiments, when the product discharge of the filter assemblies that recirculated water filtration stage is measured is less than flow threshold, can not judge that its needs clean immediately.This is one or many air purge because the washing machine of these embodiments can carry out after using filter assemblies each time and water washing operations, the partial impurities on the filter membrane of filter assemblies or film silk surface can be disposed, this increases making the product discharge of filter assemblies, and the product discharge recorded when filter assemblies sometimes can be made to use in upper once water purification program for washing is more than or equal to flow threshold.Therefore, in the further embodiment of the present invention, can first not judge to need to clean filter assemblies when judging that in step S206 product discharge is less than flow threshold.
Present inventor finds, if the product discharge measured when using filter assemblies to filter the water in cylindric washer several times continuously is all less than flow threshold, so show it can not have been made to produce discharge increase by carrying out air purge operation and water washing operations to filter assemblies.And now, then need to clean filter assemblies.Therefore, after step S210 performs, step S212 can be performed: judge whether the flow cumulative number that transfinites equals default flow and to transfinite accumulative threshold value.In one embodiment, the flow accumulative threshold value that transfinites can be 3-5 time.If the judged result of step S212 is "Yes", then perform step S214: judge to need to clean described filter assemblies.
The flow of the washing machine of the embodiment of the present invention cumulative number that transfinites can be set to 0 when dispatching from the factory.When the recirculated water filtration stage of each execution water purification program for washing, if the product discharge measured is less than flow threshold, then the cumulative number that transfinited by flow adds 1; If the product discharge measured is greater than flow threshold, then the cumulative number that transfinited by flow resets and again adds up.Upper once perform water purification program for washing time, if the product discharge again measured still is less than flow threshold, then the cumulative number that again transfinited by flow adds 1; If the product discharge again measured is not less than flow threshold, then the cumulative number that transfinited by flow resets and again adds up.By that analogy, until flow transfinites cumulative number reach default flow transfinite accumulative threshold value time judge need to clean filter assemblies.
When judging to need to clean filter assemblies, then send vision and/or audible signal reminding user and start filter assemblies cleaning procedure to clean described filter assemblies.In embodiments of the present invention, after sending described vision and/or audible signal first, after this water purification program for washing of described washing machine terminates, when described washing machine is again opened or again performs described water purification program for washing, again send vision and/or audible signal reminding user, until stop when receiving the user operation instruction starting described filter assemblies cleaning procedure sending vision and/or audible signal.That is, after sending described vision and/or audible signal first, and when each start received before the user operation instruction starting described filter assemblies cleaning procedure or each execution water purification program for washing, all send vision and/or audible signal reminding user.
