进一步地，所述方法包括如下步骤：
S1、脱水进程，滚筒以第一设定速度转动；
S2、检测洗衣机滚筒内的水位压力的信息，判断水位压力的信息是否达到预设值，如果是，则控制滚筒以第二设定速度转动并启动喷淋阀和排水泵，然后执行步骤S1；如果否，则执行步骤S3；
S3、控制滚筒以第三设定速度转动。
进一步地，所述步骤S1之前还包括步骤S0、执行排水进程，并启动排水泵；
优选的，所述排水进程中排水泵以第一排水时序进行排水；
更优选的，步骤S2启动排水泵后，所述排水泵以第二排水时序进行排水。
进一步地，步骤2中所述水位压力的信息与第二设定速度相对应，其对应关系储存在洗衣机内。
进一步地，所述第二设定速度的范围是50rpm-200rpm；
优选的，所述第二设定速度的范围是90rpm-100rpm。
进一步地，步骤S2与步骤S3之间还包括判断滚筒的转速是否达到第四设定速度，如果否，则执行步骤S1；如果是，则执行下一步。
进一步地，步骤S3之后还包括步骤S4：控制滚筒脱水运行设定的时间。
进一步地，步骤S3之后还包括步骤A)：判断设定时间内滚筒是否达到预设转速，如果否，则控制滚筒以第二设定速度转动并启动喷淋阀和排水泵，然后执行步骤S3；如果是，则执行步骤S4。
具体的，本实施例中还通过检测设定时间内滚筒是否达到预设转速，判断是否滚筒内是否残留泡沫，然后再通过清除泡沫程序进行清除，避免压力检测传感器、或者水位传感器检测水位水压信息不准确，造成无法彻底清除泡沫的问题。同时，避免由于残留泡沫在滚筒高速转动过程中，加大了电机的负荷，缩短了电机的使用寿命的问题，还能够通过检测设定时间内滚筒是否达到预设转速，检测电机是否在正常的工作状态，如果不在正常的工作状态，则降低电机的转速和负荷，确保了电机使用的安全，如果在正常状态，则控制电机高速运转设定时间进行高速脱水，进而实现电机的正常运行，保证电机的使用寿命。
同时，本实施例中对设定时间内滚筒是否达到预设转速重复的检测，一方面实现了对残留泡沫的重复检测和重复清除，提高洗衣机的洗涤效果。另一方面，能够确保电机在正常工作的状态下才执行高速转动脱水的程序，提高电机的使用寿命。
进一步地，步骤A)启动排水泵后，所述排水泵以第三排水时序进行排水；
优选的，所述第三排水时序与设定时间内滚筒达到的转速相关，其对应关系储存在洗衣机内。
所述排水泵的第三排水时序为排放第四设定时间，停止第五设定时间，优选的，所述第三设定时间为25S-35S，第四设定时间为1S-9S。步骤A)启动排水泵后，通过残留泡沫的情况确定第三排水时序，通过第三排水时序中间隔的转停，使排水泵的排水腔室内积累更多的泡沫，然后通过排水泵排出，提高泡沫清除的效率，并实现洗衣机充分清除滚筒内残余泡沫的功能。
进一步地，步骤S4之后还包括步骤S5：控制滚筒脱水运行设定的时间。
步骤S2中当水位压力的信息达到预设值后，和/或步骤S4当设定时间内滚筒未达到预设转速后，所述喷淋阀开启喷淋设定的时间；
优选的，所述设定时间的范围值为20S-40S。
进一步地，所述第一设定速度、第三设定速度和第四设定速度均大于所述第二设定速度。
最后，执行完步骤S4，滚筒停止转动，关闭排水泵。并结束洗衣机相应的程序。
综上所述，本实施例中所述洗衣机的泡沫检测及消除方法具有以下优点：
1、本实施例中所述洗衣机的泡沫检测及消除方法通过多次，多参数的检测，保证滚筒内残留泡沫全部清除干净，提高了所述洗衣机泡沫检测的准确性，并且本实施例还能够实现对电机设定时间内的运转情况进行检测，保证电机的运行正常，提高了电机的使用寿命。
实施例三
本实施例与上述实施例的区别在于，本实施例步骤S2替换为步骤S2’、检测洗衣机滚筒内的水位压力的信息，获取衣物的重量信息，根据水位压力的信息和重量信息判断滚筒内是否残留泡沫，如果是，则控制滚筒以第二设定速度转动并启动喷淋阀和排水泵，然后执行步骤S1；如果否，则执行步骤S3。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明 的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案做出的各种变化和改进，均属于本发明的保护范围。
