洗衣机是常见的家用衣物洗涤设备，根据洗涤方式进行分类，洗衣机可大致分为波轮洗衣机和滚筒洗衣机。以滚筒洗衣机为例，通常，在滚筒洗衣机对衣物进行洗涤之前，需要向洗涤水中添加相应量的洗涤剂。但是，当滚筒洗衣机投放的洗涤剂过量时，由于搅拌、水流冲击洗涤剂等原因，使得空气与洗涤剂发生连续接触，容易产生过量泡沫，若不及时清除，大量的泡沫充盈在洗涤筒内，会堵塞通气管，导致筒内压力过高从而抑制滚筒洗衣机的进水；而且内外筒充盈的泡沫还会产生阻力导致电机过载发热，出现漂洗不彻底、泡沫残留等问题，引发用户抱怨。
为了解决上述问题，现有技术中，当大量的泡沫充盈在洗涤筒内时，控制洗涤筒停止转动，静待泡沫消失。但是，上述消泡方法的效率较低，措施处置比较滞后，不能有效地消除泡沫，降低了用户的使用体验。

具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。例如，尽管本发明是结合滚筒洗衣机来描述的，但是，本发明的技术方案并不局限于此，该消泡方法显然也可以应用于波轮洗衣机、洗干一体机等其他洗涤设备，这种改变并不偏离本发明的原理和范围。
需要说明的是，在本发明的描述中，术语“第一”、“第二”、“第三”和“第四”仅用于描述目的，而不能理解为指示或暗示相对重要性。
基于背景技术中提出的技术问题，本发明提供了一种用于滚筒洗衣机的消泡方法，旨在将泡沫高度分别与第一预设警戒高度和第二预设警戒高度进行比较，能够提前预判是否需要对洗涤筒内的泡沫进行 消泡处理，避免了由于大量的泡沫充盈在洗涤筒内而堵塞通气管，从而避免了由于洗涤筒内压力过高而阻碍滚筒洗衣机的进水，避免了导致电机过载发热，确保了滚筒洗衣机的正常运行。当洗涤筒内的泡沫高度大于第一预设警戒高度但小于第二预设警戒高度时，即需要进行消泡处理时，根据滚筒洗衣机的进程阶段，执行不同的消泡操作，能够有针对性地进行消泡处理，能够快速、有效地将洗涤筒内的泡沫消除，降低了泡沫在衣物上的残留量，能够将衣物漂洗干净，进而提高了用户体验。
首先参见图1和图2，对本发明的消泡方法进行描述。其中，图1是本发明的消泡方法的主流程图；图2是本发明的消泡方法的完整流程图。
如图1所示，本发明的滚筒洗衣机包括洗涤筒，洗涤筒包括外筒以及可转动地设置在外筒内的内筒；本发明的消泡方法包括以下步骤：
S100、在滚筒洗衣机运行的过程中，获取洗涤筒内的泡沫高度；
S200、将泡沫高度分别与第一预设警戒高度和第二预设警戒高度进行比较；
S300、如果泡沫高度大于第一预设警戒高度但小于第二预设警戒高度，则获取滚筒洗衣机当前所处的进程阶段；
S400、根据进程阶段，执行不同的消泡操作。
其中，第一预设警戒高度小于第二预设警戒高度，且第二预设警戒高度小于泡沫充盈在洗涤筒内堵塞通气管时的最低高度，或者第二预设警戒高度是本领域技术人员根据实验或经验设定的泡沫不会堵塞通气管的高度，无论如何调整和设置第一预设警戒高度和第二预设警戒高度，只要能够提前预判是否需要对洗涤筒内的泡沫进行消泡处理，避免大量的泡沫充盈在洗涤筒内而堵塞通气管即可。
其中，泡沫高度是指洗涤筒内的泡沫达到的最高位置所对应的高度。
优选地，洗涤筒上设有泡沫检测口，泡沫检测口处设置有用于检测洗涤筒内的泡沫高度的泡沫检测构件，其中，泡沫检测构件可以为红外传感器、电极传感器或浮子传感器等其他检测构件，无论采取何种检测构件，对应的具体检测方法均不应对本发明构成任何的限制。
步骤S100中，可以通过泡沫检测构件实时检测泡沫高度，也可以通过泡沫检测构件按照时间间隔检测泡沫高度。其中，时间间隔可以是5s、10s或15s等，上述第一时间间隔只是示例性地，不是限制性地，本领域技术人员在实际应用中可以灵活地调整和设置第一时间间隔，无 论如何调整和设置第一时间间隔，只要能够及时地、准确地检测泡沫高度即可。
步骤S300中，如果洗涤筒内的泡沫高度大于第一预设警戒高度但小于第二预设警戒高度，例如，第一预设警戒高度为200mm，第二预设警戒高度为400mm，检测到的泡沫高度为210mm，大于第一预设警戒高度，但小于第二预设警戒高度，说明本次检测到的泡沫高度较高，已经超过了第一预设警戒高度，如果洗涤筒内的泡沫继续增多、升高，将有可能会达到第二预设警戒高度，进而有可能会堵塞通气管，影响滚筒洗衣机的正常运行，为了避免上述情况发生，需要进行消泡处理，但是，由于滚筒洗衣机在不同进程阶段的执行的操作有差异，为了能够更好地消除泡沫，则获取滚筒洗衣机的进程阶段，并根据滚筒洗衣机的进程阶段，执行不同的消泡操作。
其中，进程阶段可以包括注水阶段、洗涤阶段、排水阶段、脱水阶段、漂洗阶段等其他阶段；或者滚筒洗衣机具有烘干功能，进程阶段还可以包括烘干阶段。当然，进程阶段不限于上述列举的阶段，还可以是待机阶段等其他阶段。下文中将以洗涤阶段和漂洗阶段为例，进一步描述本发明的消泡方法。
进一步地，如图2所示，本发明的消泡方法还包括：
S500、如果泡沫高度小于第一预设警戒高度，则不执行消泡操作，继续执行设定的程序；
S600、如果泡沫高度大于第二预设警戒高度，则控制洗涤筒停止转动。
步骤S500中，如果泡沫高度小于第一预设警戒高度，例如，第一预设警戒高度为200mm，检测到的泡沫高度为180mm，小于第一预设警戒高度，说明本次检测到的泡沫高度较低，尚未达到第一预设警戒高度，不会影响滚筒洗衣机的正常运行，无需执行消泡操作，继续执行设定的程序即可。
步骤S600中，如果泡沫高度大于第二预设警戒高度，例如，第二预设警戒高度为400mm，检测到的泡沫高度为405mm，大于第二预设警戒高度，说明本次检测到的泡沫高度非常高，已经超过了第二预设警戒高度，如果洗涤筒内的泡沫继续增多、升高，将有可能会堵塞通气管，影响滚筒洗衣机的正常运行，为了避免上述情况发生，控制洗涤筒停止转动，使得洗涤筒内的洗涤水趋于静止，采用静置的方式消除泡沫，能够完全抑制泡沫的产生，并持续检测泡沫高度，当再次检测到的泡沫高度小于第一预设警戒高度时，继续执行剩余的设定程序。
需要说明的是，上述列举的第一预设警戒高度和第二预设警戒高度只是示例性地，不是限制性地，本领域技术人员在实际应用中可以根据滚筒洗衣机的型号、通气管的设置位置等信息灵活地调整和设置第一预设警戒高度和第二预设警戒高度，例如第一预设警戒高度为260mm，第二预设警戒高度为480mm等，无论如何调整和设置第一预设警戒高度和第二预设警戒高度，只要能够判断是否需要执行消泡操作即可。
需要进一步说明的是，上述过程中，步骤S300、步骤S500和步骤S600没有先后顺序，是并列的，仅仅和泡沫高度分别与第一预设警戒高度和第二预设警戒高度的比较结果相关，根据不同的比较结果执行对应的步骤即可。
下面参照图3至图5，对本发明的滚筒洗衣机处于洗涤阶段的消泡方法进行描述。其中，图3是本发明的滚筒洗衣机处于洗涤阶段的消泡方法的第一流程图；图4是本发明的滚筒洗衣机处于洗涤阶段的消泡方法的第二流程图；图5是本发明的滚筒洗衣机处于洗涤阶段的消泡方法的第三流程图。
如图3所示，步骤S400中，“根据进程阶段，执行不同的消泡操作”的步骤具体包括：
S411、如果滚筒洗衣机处于洗涤阶段，则将洗涤筒的转停比降低至第一转停比、取消激荡操作；
S412、在第一预设时间之后，再次获取洗涤筒内的泡沫高度；
S413、将再次获取到的泡沫高度分别与第一预设警戒高度和第一预设高度进行比较；
S414、根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作。
其中，第一预设高度大于第一预设警戒高度但小于第二预设警戒高度，且第一预设高度大于或等于上一次获取到的泡沫高度。
其中，上一次获取到的泡沫高度是指步骤S100中获取到的泡沫高度，且该泡沫高度满足判定执行步骤S300的条件，即该泡沫高度满足大于第一预设警戒高度但小于第二预设警戒高度的条件，例如，步骤S300中列举的检测到的泡沫高度210mm。
步骤S411中，在滚筒洗衣机处于洗涤阶段的情形下，通常情况下，为了提高洗涤效果，设置激荡操作并将洗涤筒的转停比设置的较高，以提高水流强度，因此，可以通过降低转停比、取消激荡操作等方式来降低水流强度，从而有效抑制泡沫的产生，达到了消泡的目的。
例如，洗涤筒的当前转停比为30/20，减小内筒的转动时间，将转停比降低至20/20(即第一转停比)；或者增加内筒的停止时间，将转停比降低至30/30；或者既减小内筒的转动时间，又增加内筒的停止时间，将转停比降低至25/25，通过上述方式来降低洗涤筒的转停比，从而降低滚筒洗衣机的洗涤水流强度，能够有效消除泡沫。
当然，步骤S411的消泡方法不限于上述列举的方法，也可以只将洗涤筒的转停比降低至第一转停比，也可以只取消激荡操作，本领域技术人员可以根据实际的消泡需求和消泡效果等灵活地调整和设置步骤S411的消泡方法的组合方式。
步骤S412中，在第一预设时间(例如5min)之后，才通过泡沫检测构件再次检测洗涤筒内的泡沫高度，确保在滚筒洗衣机执行降低转停比、取消激荡操作等消泡操作之后，滚筒洗衣机能够有足够的时间将洗涤筒内的泡沫消除，并根据再次获取到的泡沫高度分别与第一预设警戒高度和第一预设高度的比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作，避免了在消泡效果未达到预设效果的情况下执行剩余的设定程序，从而避免了洗涤筒内的泡沫继续升高至第二预设警戒高度，实现了为滚筒洗衣机提供最合理的消泡方法的目的，进一步提高了用户体验。
需要说明的是，上述列举的当前转停比、第一转停比以及第一预设时间只是示例性地，不是限制性地，本领域技术人员可以在实际应用中根据泡沫高度、消泡需求以及消泡效果等灵活地调整和设置当前转停比、第一转停比以及第一预设时间。
如图4所示，步骤S414中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤具体包括：
S421、如果再次获取到的泡沫高度大于或等于第一预设警戒高度但小于或等于第一预设高度，则控制洗涤筒按照第一转停比继续运行；
S422、将后续滚筒洗衣机在洗涤结束之后执行排水操作时的排空水位降低至第一预设排空水位，并在滚筒洗衣机执行排水操作时控制滚筒洗衣机执行转动排水操作；
S423、将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第一预设加速度，将洗涤筒的最高脱水速度降低至第一预设速度。
其中，排空水位是在排水阶段达到启动滚筒洗衣机的排水泵的水位，只要排水泵的水位达到排空水位，排水泵就启动排水。
其中，脱水加速度是在脱水阶段内筒的脱水速度升至设定的最高脱水速度的加速度；优选地，脱水速度是阶梯上升的。
步骤S421中，如果再次获取到的泡沫高度大于或等于第一预设警戒高度但小于或等于第一预设高度，例如，第一预设警戒高度为200mm，第一预设高度为220mm，再次检测到的泡沫高度为205mm，虽然再次检测到的泡沫高度仍然大于第一预设警戒高度，但是已经小于第一预设高度，且小于上一次检测到的泡沫高度(例如210mm)，说明泡沫在逐渐消除，泡沫高度在逐渐降低，取得了一定的消泡效果，步骤S411中采取的消泡方法有效，则继续执行该消泡操作，即控制洗涤筒按照第一转停比继续运行。
或者，第一预设警戒高度为200mm，第一预设高度为220mm，再次检测到的泡沫高度为215mm，再次检测到的泡沫高度仍然大于第一预设警戒高度，且大于上一次检测到的泡沫高度(例如210mm)，但是再次检测到的泡沫高度小于第一预设高度，说明泡沫尚未被很好地消除，泡沫高度有略微升高，但是泡沫升高的幅度不大，在可控的范围内，有可能是检测误差导致的，也有可能是消泡时间较短导致的，并不能说明步骤S411中采取的消泡方法没有效果，因此，可以继续执行步骤S411中采取的消泡方法，即控制洗涤筒按照第一转停比继续运行。
步骤S422中，将后续滚筒洗衣机在洗涤结束之后执行排水操作时的排水泵的排空水位降低至第一预设排空水位，例如，排水泵的当前排空水位为14mm，将排空水位降低至12mm(即第一预设排空水位)，当排水泵的水位达到12mm时，排水泵就启动排水，缩短了排水泵相邻两次启动的时间间隔，提高了排水泵的排水频率，能够及时地将洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
进一步地，在滚筒洗衣机执行排水操作时控制滚筒洗衣机执行转动排水操作，在内筒转动的过程中，能够带动内筒内的衣物转动，从而将充盈在其内的泡沫赶走或消除，在降低排空水位以及转动排水的共同作用下，能够更好地消除泡沫，进一步提高了消泡效果。
步骤S423中，将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第一预设加速度，例如，内筒的当前脱水加速度是25r/s，将脱水加速度降低至20r/s(即第一预设加速度)，降低了脱水加速度，从而延长了内筒的脱水速度升至最高脱水速度的时间，延长了脱水过程中产生的离心力快速升高至最大离心力的时间，避免了脱水过程中产生的离心力快速升高至最大离心力，缩短了衣物受到最大离心力挤压的作用时间，从而降低了衣物在最大离心力的作用下产生的泡沫的数量，进一步提高了消泡效果。
而且，由于延长了脱水过程中产生的离心力快速升高至最大离心力的时间，使得在衣物在相同时间点受到的离心力减小，从而减小了脱出的洗涤水量，又由于步骤S422中将排空水位降低至第一预设排空水位，即使降低了脱出的洗涤水量，也能够及时将脱出的洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
进一步地，将洗涤筒的最高脱水速度降低至第一预设速度，例如，内筒的当前最高脱水速度是1400r/min，将最高脱水速度降低至1200r/min(即第一预设速度)，降低了最高脱水速度，从而降低了脱水过程中产生的最大离心力，从而降低了衣物在最大离心力挤压的作用下产生的泡沫的数量，进一步提高了消泡效果。
当然，步骤S423的消泡方法不限于上述列举的方法，也可以只将洗涤筒的脱水加速度降低至第一预设加速度，也可以只将洗涤筒的最高脱水速度降低至第一预设速度，本领域技术人员可以根据实际的消泡需求和消泡效果等灵活地调整和设置步骤S423的消泡方法的组合方式。
在步骤S423之后，控制滚筒洗衣机执行剩余的设定程序，例如控制滚筒洗衣机执行漂洗程序等。
需要说明的是，上述列举的第一预设警戒高度、第一预设高度、当前排空水位、第一预设排空水位、当前脱水加速度、第一预设加速度、当前最高脱水速度以及第一预设速度只是示例性地，不是限制性地，本领域技术人员可以在实际应用中根据泡沫高度、消泡需求以及消泡效果等灵活地调整和设置第一预设警戒高度、第一预设高度、当前排空水位、第一预设排空水位、当前脱水加速度、第一预设加速度、当前最高脱水速度以及第一预设速度。
如图5所示，步骤S414中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤还包括：
S431、如果再次获取到的泡沫高度大于第一预设高度，则将滚筒洗衣机的转停比降低至第二转停比，其中，第二转停比小于第一转停比；
S432、将后续滚筒洗衣机在洗涤结束之后执行排水操作时的排空水位降低至第二预设排空水位，并在滚筒洗衣机执行排水操作时控制滚筒洗衣机执行转动排水操作；
S433、将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第二预设加速度，将洗涤筒的最高脱水速度降低至第二预设速度；
S434、在滚筒洗衣机脱水结束之后，获取滚筒洗衣机的设定漂洗次数；
S435、判断设定漂洗次数是否小于第一预设次数；
S436、如果设定漂洗次数小于第一预设次数，则增加漂洗次数；
S437、如果设定漂洗次数大于或等于第一预设次数，则不调整漂洗次数。
步骤S431中，如果再次获取到的泡沫高度大于第一预设高度，例如，第一预设高度为220mm，再次检测到的泡沫高度为225mm，大于第一预设高度，由于第一预设高度大于上一次检测到的泡沫高度(例如210mm)，说明泡沫没有被很好地消除，反而明显地升高，说明步骤S411中采取的消泡方法无法有效地将泡沫消除，继续执行步骤S411中采取的消泡方法，也无法将泡沫消除，为了将泡沫消除，则进一步降低洗涤筒的转停比，进一步降低滚筒洗衣机的洗涤水流强度，从而有效抑制泡沫的产生，达到了消泡的目的。
例如，洗涤筒的第一转停比为20/20，减小内筒的转动时间，将转停比降低至10/20(即第二转停比)；或者增加内筒的停止时间，将转停比降低至20/30；或者既减小内筒的转动时间，又增加内筒的停止时间，将转停比降低至15/25，通过上述方式来进一步降低洗涤筒的转停比，从而进一步降低滚筒洗衣机的洗涤水流强度，能够有效消除泡沫。
步骤S432中，将后续滚筒洗衣机在洗涤结束之后执行排水操作时的排空水位降低至第二预设排空水位，例如，排水泵的当前排空水位为14mm，将排空水位降低至10mm(即第二预设排空水位)，当排水泵的水位达到10mm时，排水泵就启动排水，缩短了排水泵相邻两次启动的时间间隔，提高了排水泵的排水频率，能够及时地将洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
进一步地，在滚筒洗衣机执行排水操作时控制滚筒洗衣机执行转动排水操作，在内筒转动的过程中，能够带动内筒内的衣物转动，从而将充盈在其内的泡沫赶走或消除，在降低排空水位以及转动排水的共同作用下，能够更好地消除泡沫，进一步提高了消泡效果。
步骤S433中，将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第二预设加速度，例如，内筒的当前脱水加速度是25r/s，将脱水加速度降低至10r/s(即第二预设加速度)，降低了脱水加速度，从而延长了内筒的脱水速度升至最高脱水速度的时间，延长了脱水过程中产生的离心力快速升高至最大离心力的时间，避免了脱水过程中产生的离心力快速升高至最大离心力，缩短了衣物受到最大 离心力挤压的作用时间，从而降低了衣物在最大离心力的作用下产生的泡沫的数量，进一步提高了消泡效果。
而且，由于延长了脱水过程中产生的离心力快速升高至最大离心力的时间，使得在衣物在相同时间点受到的离心力减小，从而减小了脱出的洗涤水量，又由于步骤S432中将排空水位降低至第二预设排空水位，即使降低了脱出的洗涤水量，也能够及时将脱出的洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
进一步地，将洗涤筒的最高脱水速度降低至第二预设速度，例如，内筒的当前最高脱水速度是1400r/min，将最高脱水速度降低至1000r/min(即第二预设速度)，降低了最高脱水速度，从而降低了脱水过程中产生的最大离心力，从而降低了衣物在最大离心力挤压的作用下产生的泡沫的数量，进一步提高了消泡效果。
当然，步骤S433的消泡方法不限于上述列举的方法，也可以只将洗涤筒的脱水加速度降低至第二预设加速度，也可以只将洗涤筒的最高脱水速度降低至第二预设速度，本领域技术人员可以根据实际的消泡需求和消泡效果等灵活地调整和设置步骤S433的消泡方法的组合方式。
步骤S434中，由于步骤S431中的再次获取到的泡沫高度大于第一预设高度，说明洗涤筒内的泡沫较多，即便进行了消泡处理，也有可能会出现漂洗不彻底、泡沫残留等问题，为了避免上述情况发生，可能需要较多次的漂洗才能够将衣物票次干净，但是用户可能已经知道洗涤剂投放过量，设置了比正常漂洗次数多的漂洗次数，为了避免资源的浪费，则获取滚筒洗衣机的设定漂洗次数，并根据已经设定的漂洗次数来判断是否增加漂洗次数。
步骤S436中，如果设定漂洗次数小于第一预设次数，例如，第一预设次数是5次，设定漂洗次数是3次，小于第一预设次数，说明设定的漂洗次数较少，难以将衣物漂洗干净，为了避免泡沫残留在衣物上，则增加漂洗次数，例如增加1次或2次，且增加后的漂洗次数不得大于第一预设次数。
步骤S437中，如果设定漂洗次数大于或等于第一预设次数，例如，第一预设次数是5次，设定漂洗次数是6次，大于第一预设次数，说明设定的漂洗次数非常多，能够将衣物漂洗干净，无需调整漂洗次数。
需要说明的是，上述列举的第一预设高度、第一转停比、第二转停比、当前排空水位、第二预设排空水位、当前脱水加速度、第二预设加速度、当前最高脱水速度、第二预设速度以及第一预设次数只是示例性地，不是限制性地，本领域技术人员可以在实际应用中根据泡沫 高度、消泡需求以及消泡效果等灵活地调整和设置第一预设高度、第一转停比、第二转停比、当前排空水位、第二预设排空水位、当前脱水加速度、第二预设加速度、当前最高脱水速度、第二预设速度以及第一预设次数。
需要进一步说明的是，上述过程中，步骤S436和步骤S437没有先后顺序，是并列的，仅仅和设定漂洗次数是否小于第一预设次数的判断结果相关，根据不同的判断结果执行对应的步骤即可。
尽管图中未示出，步骤S414中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤还包括：
S441、如果再次获取到的泡沫高度小于第一预设警戒高度，则控制滚筒洗衣机执行剩余的设定程序。
步骤S441中，如果再次获取到的泡沫高度小于第一预设警戒高度，例如，第一预设警戒高度为200mm，再次检测到的泡沫高度为190mm，小于第一预设警戒高度，说明此时的泡沫高度已经降低至第一预设警戒高度以下，警戒消除，能够正常运行，则控制滚筒洗衣机执行剩余的设定程序。
需要说明的是，上述过程中，步骤S421、步骤S431和步骤S441没有先后顺序，是并列的，仅仅和再次获取到的泡沫高度分别与第一预设警戒高度和第一预设高度的比较结果相关，根据不同的比较结果执行对应的步骤即可。
下面参照图6至图8，对本发明的滚筒洗衣机处于漂洗阶段的消泡方法进行描述。其中，图6是本发明的滚筒洗衣机处于漂洗阶段的消泡方法的第一流程图；图7是本发明的滚筒洗衣机处于漂洗阶段的消泡方法的第二流程图；图8是本发明的滚筒洗衣机处于漂洗阶段的消泡方法的第三流程图。
如图6所示，步骤S400中，“根据进程阶段，执行不同的消泡操作”的步骤还包括：
S451、如果滚筒洗衣机处于漂洗阶段，则将洗涤筒的转动频率降低至预设转动频率；
S452、在第二预设之间之后，再次获取洗涤筒内的泡沫高度；
S453、将再次获取到的泡沫高度分别与第一预设警戒高度和第二预设高度进行比较；
S454、根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作；
其中，第二预设高度大于第一预设警戒高度但小于第二预设警戒高度，且第二预设高度大于或等于上一次获取到的泡沫高度。
其中，上一次获取到的泡沫高度是指步骤S100中获取到的泡沫高度，且该泡沫高度满足判定执行步骤S300的条件，即该泡沫高度满足大于第一预设警戒高度但小于第二预设警戒高度的条件，例如，步骤S300中列举的检测到的泡沫高度210mm。
步骤S451中，在滚筒洗衣机处于漂洗阶段的情形下，通常情况下，为了提高漂洗效果，将洗涤筒的转动频率设置的较高，以提高水流强度，因此，可以通过降低转动频率等方式来降低水流强度，从而有效抑制泡沫的产生，达到了消泡的目的。
例如，洗涤筒的当前转动频率为每30s转动10s，将转动频率降低至每30s转动5s(即预设转动频率)，或者将转动频率降低至每40s转动10s，或者将转动频率降低至每28s转动8s，通过上述方式来降低洗涤筒的转动频率，从而降低滚筒洗衣机的洗漂洗水流强度，能够有效消除泡沫。
步骤S452中，在第二预设时间(例如5min)之后，才通过泡沫检测构件再次检测洗涤筒内的泡沫高度，确保在滚筒洗衣机执行降低转动频率等消泡操作之后，滚筒洗衣机能够有足够的时间将洗涤筒内的泡沫消除，并根据再次获取到的泡沫高度分别与第一预设警戒高度和第二预设高度的比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作，避免了在消泡效果未达到预设效果的情况下执行剩余的设定程序，从而避免了洗涤筒内的泡沫继续升高至第二预设警戒高度，实现了为滚筒洗衣机提供最合理的消泡方法的目的，进一步提高了用户体验。
虽然，上述列举的第二预设时间与第一预设时间相同，但这只是示例性地，不是限制性地，在实际应用中，本领域技术人员也可以将第二预设时间设置为与第一预设时间不相同，例如，第一预设时间为4min，第二预设时间为6min，本发明对此不作任何的限制。
需要说明的是，上述列举的当前转动频率、预设转动频率以及第二预设时间只是示例性地，不是限制性地，本领域技术人员可以在实际应用中根据泡沫高度、消泡需求以及消泡效果等灵活地调整和设置当前转动频率、预设转动频率以及第二预设时间。
如图7所示，步骤S454中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤具体包括：
S461、如果再次获取到的泡沫高度大于或等于第一预设警戒高度但小于或等于第二预设高度，则控制洗涤筒按照预设转动频率继续运行；
S462、将后续滚筒洗衣机在漂洗结束之后执行排水操作时的排空水位降低至第三预设排空水位；
S463、在滚筒洗衣机排水结束之后，控制滚筒洗衣机执行喷淋漂洗操作，并控制滚筒洗衣机执行转动排水操作；
S464、将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第三预设加速度，将洗涤筒的最高脱水速度降低至第三预设速度；
S465、在滚筒洗衣机脱水结束之后，控制滚筒洗衣机再次执行喷淋漂洗操作；
S466、在滚筒洗衣机再次喷淋漂洗结束之后，获取滚筒洗衣机的剩余漂洗次数；
S467、判断剩余漂洗次数是否大于或等于第二预设次数；
若是，则执行步骤S468；
若否，则执行捕捉S469；
S468、控制滚筒洗衣机继续执行漂洗操作；
S469、控制滚筒洗衣机结束运行。
其中，排空水位是在排水阶段达到启动滚筒洗衣机的排水泵的水位，只要排水泵的水位达到排空水位，排水泵就启动排水。
其中，脱水加速度是在脱水阶段内筒的脱水速度升至设定的最高脱水速度的加速度；优选地，脱水速度是阶梯上升的。
步骤S461中，如果再次获取到的泡沫高度大于或等于第一预设警戒高度但小于或等于第二预设高度，例如，第一预设警戒高度为200mm，第二预设高度为225mm，再次检测到的泡沫高度为205mm，虽然再次检测到的泡沫高度仍然大于第一预设警戒高度，但是已经小于第二预设高度，且小于上一次检测到的泡沫高度(例如210mm)，说明泡沫在逐渐消除，泡沫高度在逐渐降低，取得了一定的消泡效果，步骤S451中采取的消泡方法有效，则继续执行该消泡操作，即控制洗涤筒按照预设转动频率继续运行。
或者，第一预设警戒高度为200mm，第二预设高度为225mm，再次检测到的泡沫高度为215mm，再次检测到的泡沫高度仍然大于第一预设警戒高度，且大于上一次检测到的泡沫高度(例如210mm)，但是再次检测到的泡沫高度小于第二预设高度，说明泡沫尚未被很好地消除，泡沫高度有略微升高，但是泡沫升高的幅度不大，在可控的范围内，有 可能是检测误差导致的，也有可能是消泡时间较短导致的，并不能说明步骤S451中采取的消泡方法没有效果，因此，可以继续执行步骤S451中采取的消泡方法，即控制洗涤筒按照预设转动频率继续运行。
虽然，上述列举的第二预设高度与第一预设高度不相同，但这只是示例性地，不是限制性地，在实际应用中，本领域技术人员也可以将第二预设高度设置为等于第一预设高度，例如，第一预设高度为222mm，第二预设高度也为222mm，本发明对此不作任何的限制。
步骤S462中，将后续滚筒洗衣机在漂洗结束之后执行排水操作时的排水泵的排空水位降低至第三预设排空水位，例如，排水泵的当前排空水位为14mm，将排空水位降低至8mm(即第三预设排空水位)，当排水泵的水位达到8mm时，排水泵就启动排水，缩短了排水泵相邻两次启动的时间间隔，提高了排水泵的排水频率，能够及时地将洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
步骤S463中，在滚筒洗衣机排水结束之后，控制滚筒洗衣机执行喷淋漂洗操作，例如喷淋漂洗20s；并控制滚筒洗衣机执行转动排水操作，将内筒内的衣物转动至内筒的前部(即靠近窗垫的位置)，使得喷淋的洗涤水能够全部喷淋至衣物上，能够有效地消除泡沫，进一步提高了消泡效果。
步骤S464中，将后续滚筒洗衣机排水结束之后执行脱水操作时的洗涤筒的脱水加速度降低至第三预设加速度，例如，内筒的当前脱水加速度是25r/s，将脱水加速度降低至5r/s(即第三预设加速度)，降低了脱水加速度，从而延长了内筒的脱水速度升至最高脱水速度的时间，延长了脱水过程中产生的离心力快速升高至最大离心力的时间，避免了脱水过程中产生的离心力快速升高至最大离心力，缩短了衣物受到最大离心力挤压的作用时间，从而降低了衣物在最大离心力的作用下产生的泡沫的数量，进一步提高了消泡效果。
而且，由于延长了脱水过程中产生的离心力快速升高至最大离心力的时间，使得在衣物在相同时间点受到的离心力减小，从而减小了脱出的洗涤水量，又由于步骤S462中将排空水位降低至第三预设排空水位，即使降低了脱出的洗涤水量，也能够及时将脱出的洗涤水排出，避免了内筒在转动的过程中产生击打作用，从而避免了产生泡沫。
进一步地，将洗涤筒的最高脱水速度降低至第三预设速度，例如，内筒的当前最高脱水速度是1400r/min，将最高脱水速度降低至800r/min(即第三预设速度)，降低了最高脱水速度，从而降低了脱水过程中产生的最大离心力，从而降低了衣物在最大离心力挤压的作用下产生的泡沫的数量，进一步提高了消泡效果。
当然，步骤S464的消泡方法不限于上述列举的方法，也可以只将洗涤筒的脱水加速度降低至第三预设加速度，也可以只将洗涤筒的最高脱水速度降低至第三预设速度，本领域技术人员可以根据实际的消泡需求和消泡效果等灵活地调整和设置步骤S464的消泡方法的组合方式。
S465、在滚筒洗衣机脱水结束之后，控制滚筒洗衣机再次执行喷淋漂洗操作，例如喷淋漂洗25s，进一步消除泡沫，降低衣物上泡沫的残留量。
步骤S466中，由于不确定当前的漂洗阶段(即步骤S451中确定的漂洗阶段)是否是滚筒洗衣机的最后一次漂洗，当步骤S465消泡完成以后，则获取滚筒洗衣机的剩余漂洗次数，并根据剩余的漂洗次数来判断是否结束运行或继续执行漂洗操作。
步骤S468中，如果剩余漂洗次数大于或等于第二预设次数，例如，第二预设次数是1次，剩余漂洗次数是2次，大于第二预设次数，说明当前的漂洗阶段不是滚筒洗衣机的最后一次漂洗，还有2次漂洗尚未执行，则控制滚筒洗衣机继续执行漂洗操作。
步骤S469中，如果剩余漂洗次数小于第二预设次数，例如，第二预设次数是1次，剩余漂洗次数是0次，小于第二预设次数，说明当前的漂洗阶段是滚筒洗衣机的最后一次漂洗，则在滚筒洗衣机脱水完成之后，控制滚筒洗衣机结束运行。
需要说明的是，上述列举的第一预设警戒高度、第二预设高度、当前排空水位、第三预设排空水位、喷淋漂洗时间、当前脱水加速度、第三预设加速度、当前最高脱水速度、第三预设速度以及第二预设次数只是示例性地，不是限制性地，本领域技术人员可以在实际应用中根据泡沫高度、消泡需求以及消泡效果等灵活地调整和设置第一预设警戒高度、第二预设高度、当前排空水位、第三预设排空水位、喷淋漂洗时间、当前脱水加速度、第三预设加速度、当前最高脱水速度、第三预设速度以及第二预设次数。
需要进一步说明的是，上述过程中，步骤S468和步骤S469没有先后顺序，是并列的，仅仅和剩余漂洗次数是否大于或等于第二预设次数的判断结果相关，根据不同的判断结果执行对应的步骤即可。
如图8所示，步骤S454中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤还包括：
S471、如果再次获取到的泡沫高度大于第二预设高度，则控制洗涤筒停止转动，并使滚筒洗衣机执行排水操作；
S472、在滚筒洗衣机排水结束之后，控制滚筒洗衣机执行脱水操作；
S473、在滚筒洗衣机脱水结束之后，获取滚筒洗衣机的剩余漂洗次数；
S474、判断剩余漂洗次数是否小于第三预设次数；
若否，则执行步骤S475；
若是，则执行步骤S476；
S475、控制滚筒洗衣机继续执行漂洗操作；
S476、获取滚筒洗衣机的设定漂洗次数；
S477、判断设定漂洗次数是否小于第四预设次数；
若是，则执行步骤S478；
若否，则执行步骤S479；
S478、增加漂洗次数；
S479、控制滚筒洗衣机结束运行。
步骤S471中，如果再次获取到的泡沫高度大于第二预设高度，例如，第二预设高度为225mm，再次检测到的泡沫高度为230mm，大于第二预设高度，由于第二预设高度大于上一次检测到的泡沫高度(例如210mm)，说明泡沫没有被很好地消除，反而明显地升高，说明步骤S451中采取的消泡方法无法有效地将泡沫消除，继续执行步骤S451中采取的消泡方法，也无法将泡沫消除，则控制洗涤筒停止转动，并使滚筒洗衣机执行排水操作，以降低水位，防止泡沫堵塞通气管。
步骤S473中，由于不确定当前的漂洗阶段(即步骤S451中确定的漂洗阶段)是否是滚筒洗衣机的最后一次漂洗，当步骤S472脱水完成以后，则获取滚筒洗衣机的剩余漂洗次数，并根据剩余的漂洗次数来判断是否结束运行或继续执行漂洗操作。
步骤S475中，如果剩余漂洗次数大于或等于第三预设次数，例如，第三预设次数是1次，剩余漂洗次数是3次，等于第三预设次数，说明当前的漂洗阶段不是滚筒洗衣机的最后一次漂洗，还有3次漂洗尚未执行，则控制滚筒洗衣机继续执行漂洗操作。
步骤S476中，如果剩余漂洗次数小于第三预设次数，例如，第三预设次数是1次，剩余漂洗次数是0次，小于第三预设次数，说明当前的漂洗阶段是滚筒洗衣机的最后一次漂洗，但是步骤S471中再次获取到的泡沫高度大于第二预设高度，洗涤筒内的泡沫仍然较多，尚未将衣物漂洗干净，还需要更多次的漂洗才能够将衣物漂洗干净，为了判断是否增加漂洗次数，则获取滚筒洗衣机的设定漂洗次数，并根据设定漂洗次数来判断是否增加漂洗次数。
步骤S478中，如果设定漂洗次数小于第四预设次数，例如，第四预设次数是5次，设定漂洗次数是3次，小于第四预设次数，说明设定的漂洗次数较少，为了将衣物漂洗干净，则可以增加漂洗次数，例如增加1次或2次，且增加后的漂洗次数不得大于第四预设次数。
步骤S479中，如果设定漂洗次数大于或等于第四预设次数，例如，第四预设次数是5次，设定漂洗次数是6次，大于第四预设次数，说明设定的漂洗次数非常多，且在最后一次漂洗过程中，检测到的泡沫高度仍然高于第一预设警戒高度，经消泡处理后再次检测到的泡沫高度大于第二预设高度，仍然无法将泡沫消除，有可能是检测构件故障导致，也有可能是洗涤剂投放太多导致，无论是何种原因都不适宜继续执行漂洗操作，则控制滚筒洗衣机结束运行。
需要说明的是，上述过程中，步骤S475和步骤S476没有先后顺序，是并列的，仅仅和剩余漂洗次数是否小于第三预设次数的判断结果相关，根据不同的判断结果执行对应的步骤即可。步骤S478和步骤S479没有先后顺序，是并列的，仅仅和设定漂洗次数是否小于第四预设次数的判断结果相关，根据不同的判断结果执行对应的步骤即可。
尽管图中未示出，步骤S454中，“根据比较结果，选择性地控制滚筒洗衣机执行剩余的设定程序或者继续执行消泡操作”的步骤还包括：
S481、如果再次获取到的泡沫高度小于第一预设警戒高度，则控制滚筒洗衣机执行剩余的设定程序。
步骤S481中，如果再次获取到的泡沫高度小于第一预设警戒高度，例如，第一预设警戒高度为200mm，再次检测到的泡沫高度为185mm，小于第一预设警戒高度，说明此时的泡沫高度已经降低至第一预设警戒高度以下，警戒消除，能够正常运行，则控制滚筒洗衣机执行剩余的设定程序。
需要说明的是，上述过程中，步骤S461、步骤S471和步骤S481没有先后顺序，是并列的，仅仅和再次获取到的泡沫高度分别与第一预设警戒高度和第一预设高度的比较结果相关，根据不同的比较结果执行对应的步骤即可。
此外，还需要说明的是，虽然，上述列举的第一预设排空水位、第二预设排空水位以及第三预设排空水位互不相同，第一预设加速度、第二预设加速度以及第三预设加速度互不相同，第二预设速度、第一预设速度以及第三预设速度互不相同，但这只是示例性地，不是限制性地，在实际应用中，本领域技术人员也可以将第一预设排空水位、第二预设排空水位以及第三预设排空水位中的任意两个或全部设置为相 同；也可以将第一预设加速度、第二预设加速度以及第三预设加速度中的任意两个或全部设置为相同；也可以将第二预设速度、第一预设速度以及第三预设速度中的任意两个或全部设置为相同，本发明对此不作任何的限制。
