对于上述步骤2的具体实现，本实施例提供了一种优选实施方式，即上述步骤2可以包括：步骤21，比较第一脱水转速值与预设转速值的大小；步骤22，如果第一脱水转速值＜预设转速值，则按照第一脱水转速值执行第一脱水操作；步骤23，如果第一脱水转速值≥预设转速值，则按照预设转速值执行第二脱水操作，该流程结束。基于此，无论洗衣机中衣服的偏心值多高，都可以启动脱水操作，且可以按照相应的转速值进行脱水操作。
在上述步骤3中，具体地，是在执行第一脱水操作之后，检测当前偏心值作为第二偏心值。从而为进一步执行脱水操作提供基础。
对于上述步骤2的具体实现，本实施例提供了一种优选实施方式，即上述步骤4可以包括：步骤41，比较第二脱水转速值与预设转速值的大小；步骤42，如果第二脱水转速值＜预设转速值，则按照第二脱水转速值执行第三脱水操作，并将上述第二偏心值的值赋值给上述第一偏心值；步骤43，如果第二脱水转速值≥预设转速值，则按照预设转速值执行第四脱水操作。其中，在步骤42之后，将第二偏心值赋给第一偏心值，然后执行步骤3。基于此，在前一次脱水操作的脱水效果 没有达到最佳时，又执行了一次脱水操作，从而逐步降低偏心值，提升脱水效果。
在上述步骤5中，当摆平操作的执行次数超过预设阈值后，不再执行摆平操作。从而防止洗衣机无限循环摆平操作。
实施例二
图2是根据本发明实施例的洗衣机脱水流程图，如图2所示，该方法包括以下步骤(步骤S201-步骤S222)：
步骤S201，选择脱水模式A,预设脱水转速值V。
步骤S202，进行初次偏心检测，并将检测值赋值为初次偏心值OOB1。
步骤S203，确定初次偏心值OOB1的范围Xi≤OOB1＜Xi+1。
步骤S204，确定与OOB1对应的脱水转速值Va＝Vi。
步骤S205，判断Va＜V是否成立；如果是，则执行步骤S209，如果否，则执行步骤S206。
步骤S206，Va≥V，将Va赋值为V，即Va＝V。
步骤S207，以赋值后的转速Va脱水。
步骤S208，脱水流程结束。
步骤S209，Va＜V，以Va转速脱水。
步骤S210，再进行偏心检测，此次检测值为OOB2。
步骤S211，判断OOB2＜OOB1是否成立；如果是，则执行步骤S216，如果否，则执行步骤S212。
步骤S212，将摆平操作次数n加1。
步骤S213，判断n＜N(摆平预设最高次数，可设置N＜10)是否成立；如果是，则执行步骤S215，如果否，则执行步骤S214。
步骤S214，该流程结束。
步骤S215，执行摆平操作。
步骤S216，确定与OOB1对应的脱水转速值Vb。
步骤S217，判断Vb＜V是否成立；如果是，则执行步骤S218，如果否，则执行步骤S220。
步骤S218，以Vb转速脱水。
步骤S219，将OOB2的值赋给OOB1，即OOB1＝OOB2。
步骤S220，将Vb赋值为V，即Vb＝V。
步骤S221，以赋值后的转速Vb脱水。
步骤S222，脱水流程结束。
现有洗衣机在洗完衣服后会进入脱水运行。脱水分为两次：预脱和终脱。脱水前会进行偏心检测，根据检测的偏心值大小，决定脱水速度的大小。表1所示的是偏心值与脱水转速的对应关系表。偏心值小，则脱水转速大，偏心值大，则脱水转速小。以此保证在振动较小的情况下，进行脱水运行。
表1
偏心值OOB1/OOB2 (0,X1) [X1,X2) .... [Xi,Xi+1) ...... [Xn,Xn+1)
脱水转速值Va/Vb V0 V1 .... Vi ...... Vn
本实施例提出一种循环偏心检测及脱水的方法，针对特殊负载选定脱水模式A。脱水前设定脱水转速V。经过初次偏心检测得到偏心值OOB1，据此选定一个初始的脱水速度Va。当Va≥设定脱水转速V，Va赋值为V，然后以赋值之后的转速Va脱水，脱水结束(这种情况一般不会发生)。当Va＜设定脱水转速V，进入转速Va脱水，然后又进入偏心检测，针对再次检测偏心值OOB2大小分两种情况处理：再次偏心值OOB2比初次偏心值OOB1小时，进入更高转速Vb脱水，此时分两种情况：Vb≥V时，Vb赋值为V，以转速Vb脱水并结束脱水流程；如果Vb＜V，则以转速Vb脱水，并将OOB1赋值为OOB2后又进行偏心检测，如此循环，直至脱水转速达到设定脱水转速为止；如果再次偏心值OOB2比初次偏心值OOB1大时，则进行有限次数N的摆平动作，每次摆平后检测偏心值，根据偏心值和初次偏心值比较的结果决定进入脱水还是进入摆平，如此次循环，直至摆平次数达到设定次数而偏心值OOB2仍旧高于初次偏心值时，即使上次脱水转速Vb＜设定转速V，仍结束脱水。如此，最大限度地保证洗涤负载量少且吸水性好的衣服负载能脱水且能最大程度的脱水。
实施例三
对应于图1介绍的洗衣机脱水方法，本实施例提供了一种洗衣机 脱水装置，如图3所示的洗衣机脱水装置的结构框图，该装置包括：

第二脱水模块40，连接至第二检测模块30，用于在第二偏心值＜第一偏心值的情况下，根据第二脱水转速值与预设转速值的比较结果，执行相应的脱水操作，并将第二偏心值的值赋值给第一偏心值；
摆平模块50，连接至第二检测模块30，在第二偏心值≥第一偏心值的情况下，执行摆平操作。
通过本实施例，洗衣机在洗涤负载量少且吸水性好的衣服时，可以进入脱水，且能最大程度的脱水，提高了洗衣机的脱水效果，提升用户体验。
对于上述第一脱水模块20的具体实现，本实施例提供了一种优选实施方式，即上述第一脱水模块20可以包括：第一比较单元，用于比较第一脱水转速值与预设转速值的大小；第一处理单元，用于在第一脱水转速值＜预设转速值的情况下，按照第一脱水转速值执行第一脱水操作；在第一脱水转速值≥预设转速值的情况下，按照预设转速值执行第二脱水操作。基于此，无论洗衣机中衣服的偏心值多高，都可以启动脱水操作，且可以按照相应的转速值进行脱水操作。
需要说明的是，上述第二检测模块30具体用于在执行第一脱水操作之后，检测当前偏心值作为第二偏心值。在第一处理单元执行完第二脱水操作后，该脱水流程结束。
对于上述第二脱水模块40的具体实现，本实施例提供了一种优选实施方式，即上述第二脱水模块40可以包括：第二比较单元，用于比较第二脱水转速值与预设转速值的大小；第二处理单元，用于在第二脱水转速值＜预设转速值的情况下，按照第二脱水转速值执行第三脱水操作，并将上述第二偏心值的值赋值给上述第一偏心值；在第二脱 水转速值≥预设转速值的情况下，按照预设转速值执行第四脱水操作。基于此，在前一次脱水操作的脱水效果没有达到最佳时，又执行了一次脱水操作，从而逐步降低偏心值，提升脱水效果。
上述摆平模块50，具体用于在摆平操作的执行次数超过预设阈值后，不再执行摆平操作。从而防止洗衣机无限循环摆平操作。
本实施例还提供了一种洗衣机，如图4所示的洗衣机的结构框图，该洗衣机包括上述介绍的洗衣机脱水装置，实现针对负载量少且吸水性的衣服的顺利脱水。
从以上的描述中可知，本发明主要实现了以下几点：1)在对负载少且吸水性好的衣服进行脱水时，通过多次循环脱水，脱水转速逐步提高，使衣服能脱水且能脱干；2)脱水前检测的偏心值很高，为控制振动，让洗衣机进入低速脱水；3)随着脱水后偏心值的降低，更高脱水转速的振动得到控制，可使脱水转速进一步提高，直至达到尽可能高的转速或设定转速，使衣服尽可能脱干。
当然，以上是本发明的优选实施方式。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明基本原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
