一种排水泵控制方法、装置、设备及存储介质
本申请要求于2020年10月30日提交中国国家知识产权局、申请号为202011196586.5、发明名称为“一种排水泵控制方法、装置、设备及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于电器设备技术领域，具体涉及一种排水泵控制方法、装置、设备及存储介质。
背景技术
洗衣机、空调、洗碗机等家电设备中都设置有排水泵及其对应的电机，电机包括的电机轴与排水泵的叶轮连接，通过电机驱动叶轮旋转进行排水。电机的转动方向与排水泵的叶轮的转动方向一致，通过改变电机U、V、W三相的控制参数可以控制电机改变转动方向，从而带动排水泵的叶轮改变转动方向。不管排水泵的叶轮正转还是反转，其形成的吸力都能使家电设备内的水排出。
目前相关技术中，在家电设备运行排水程序时通过主控板控制排水泵的电机以恒定的转速运转进行排水，排水完成后控制电机停机。但在排水泵堵塞的情况下，仍控制电机以较高的恒定转速运行，会导致电机升温，排水泵会产生很大噪音，且排水效率很低，造成资源浪费。

需要注意的是，除非另有说明，本申请使用的技术术语或者科学术语应当为 本申请所属领域技术人员所理解的通常意义。
下面结合附图来描述根据本申请实施例提出的一种排水泵控制方法、装置、设备及存储介质。
本申请实施例提供了一种排水泵控制方法，该方法在控制排水泵排水的过程中，控制排水泵的电机交替地进行正转和反转，电机带动排水泵的叶轮进行正转反转，如此头发或线头等杂物沿着叶轮转动的一个方向缠绕在排水泵的叶轮上后，电机转动方向改变，有助于缠绕在叶轮上的杂物反向缠绕从叶轮上解除下来，从而能够有效减少排水泵堵塞的情况。而且该方法在电机运行过程中实时依据电机运行参数来确定排水泵在当前方向上是否发生了堵塞，并在确定发生堵塞时控制电机切换为反方向运转，避免排水泵在某个方向上堵塞时仍按照该方向继续运转，在排水泵单向堵塞的情况下，既能确保较高的排水效率，又不会使电机升温，而且避免排水泵产生很大噪音，减少了排水泵单向堵塞情况下的资源浪费。
参见图1，该方法具体包括以下步骤：
步骤101：每隔第一预设时长控制排水泵的电机改变转动方向。
本申请实施例的执行主体为设置有排水泵的家电设备或设置于该家电设备内的主控芯片。家电设备可以包括洗衣机、洗碗机、空调等。
在家电设备控制排水泵排水的过程中，周期性地控制排水泵的电机改变转动方向。具体地，在开启排水泵进行排水时，先控制排水泵电机按照第一方向运转，第一方向可以为顺时针方向或逆时针方向。从电机启动运转时开始计时，将计时的时长与第一预设时长进行比较，若计时的时长小于第一预设时长，则继续控制电机按照第一方向运转。若计时的时长大于或等于第一预设时长，则控制电机的运转方向切换为第二方向，第二方向与第一方向相反。控制电机按照第二方向运转第一预设时长后，再控制电机的运转方向切换为第一方向。如此循环控制电机运转方向的切换。
上述第一预设时长可以为1min、1.5min或2min等。本申请实施例并不具体限制第一预设时长的具体取值，实际应用中可根据需求进行设定。
由于家电设备需要排出的水溶液中可能存在一些头发或线头等杂物，这些杂物随水流经过排水泵的叶轮时，容易缠绕在叶轮上，阻碍叶轮的正常转动，造成排水泵堵塞。本步骤周期性地改变电机的运转方向，有助于缠绕在叶轮上的杂物 反向缠绕从叶轮上解除下来，能够有效减少排水泵堵塞的情况。
步骤102：实时采集电机转动过程中的电机运行参数。
在本申请实施例中，电机运行参数可以为电机的相电流、运行功率、转速或转矩等。
若电机运行参数采用电机的相电流，则在电机运行过程中通过电流检测电路对电机的U、V、W任一相的电流进行采样，得到电机的相电流。
若电机运行参数采用电机的运行功率，则在电机运行过程中通过上述方式采样得到电机的相电流。通过电压检测电路对施加到电机上的电压进行检测。计算采样得到的相电流与检测的电压之间的乘积，得到电机的运行功率。
若电机运行参数采用电机的转速，则可以在电机上设置用于检测转速的传感器，通过设置的传感器来检测电机的转速。或者，通过上述电流检测电路和电压检测电路分别检测出电机的相电流和电压。根据检测的相电流和电压，通过无位置传感器控制算法来确定电机的转速。
若电机运行参数采用电机的转矩，则通过上述电流检测电路和电压检测电路分别检测出电机的相电流和电压。根据相电流和电压，计算出电机的运行功率。以及通过上述任一方式检测出电机的转速。计算电机的运行功率与转速的比值，该比值即为电机的转矩。
通过本步骤的方式采集到电机转动过程中的电机运行参数后，通过如下步骤103的操作来判断排水泵在当前转动方向上是否堵塞。
步骤103：根据当前的电机运行参数，确定排水泵在第一方向上是否堵塞，第一方向为当前转动方向。
在本申请的一些实施例中，电机运行参数包括电机的相电流，且家电设备中预先设置了U、V、W各相对应的预设电流阈值，预设电流阈值可以为1A或1.5A等。通过步骤102的方式检测到电机的相电流之后，从U、V、W各相对应的预设电流阈值中获取与检测的相电流属于同一相的预设电流阈值。比较电机运行参数包括的相电流与该预设电流阈值，确定电机运行参数包括的相电流是否大于该预设电流阈值。如果电机运行参数包括的相电流大于该预设电流阈值，则确定排水泵在第一方向上堵塞。如果电机运行参数包括的相电流小于或等于该预设电流阈值，则确定排水泵在第一方向上未堵塞。
在本申请的另一些实施例中，电机运行参数包括电机的运行功率，家电设备中预先设置了预设功率阈值，预设功率阈值可以为15w或18w等。通过步骤102的方式检测到电机的运行功率之后，比较电机运行参数包括的运行功率与该预设功率阈值，确定电机运行参数包括的运行功率是否大于预设功率阈值；如果电机运行参数包括的运行功率大于预设功率阈值，则确定排水泵在第一方向上堵塞。如果电机运行参数包括的运行功率小于或等于该预设功率阈值，则确定排水泵在第一方向上未堵塞。
在本申请的另一些实施例中，电机运行参数包括电机的转速，家电设备中预先设置了预设转速阈值，预设转速阈值可以为500r/min或800r/min等。通过步骤102的方式检测到电机的转速之后，比较电机运行参数包括的转速与该预设转速阈值，确定电机运行参数包括的转速是否小于预设转速阈值。如果电机运行参数包括的转速小于预设转速阈值，则确定排水泵在第一方向上堵塞。如果电机运行参数包括的转速大于或等于该预设转速阈值，则确定排水泵在第一方向上未堵塞。
在本申请的一些实施例中，电机运行参数包括电机的转矩，家电设备中预先设置了预设转矩阈值，预设转矩阈值可以为0.5N·m或0.8N·m等。通过步骤102的方式检测到电机的转矩之后，比较电机运行参数包括的转矩与该预设转矩阈值，确定电机运行参数包括的转矩是否大于预设转矩阈值。如果电机运行参数包括的转矩大于预设转矩阈值，则确定排水泵在第一方向上堵塞。如果电机运行参数包括的转矩小于或等于该预设转矩阈值，则确定排水泵在第一方向上未堵塞。
在本申请的一些实施例中，可以仅采用相电流、运行功率、转速、转矩等电机运行参数中的一种来检测排水泵在第一方向上是否堵塞。在本申请的另一些实施例中，也可以采用两种或两种以上的电机运行参数来检测，只有在通过所采用的每种电机运行参数均检测出堵塞，才确定排水泵在第一方向上堵塞，以提高检测的准确性。
若本步骤确定出排水泵在第一方向上未堵塞，且第一预设时长到达，则再控制电机按照与第一方向相反的第二方向转动，并通过步骤102和103的方式确定排水泵在第二方向上是否堵塞。若本步骤确定出排水泵在第一方向上堵塞，则执行如下步骤104的操作。
步骤104：根据排水泵在第一方向上堵塞，控制电机按照第二方向转动，第二 方向与第一方向相反。
若通过上述任一实施例的方式检测出排水泵在第一方向上堵塞，则控制电机将转动方向切换为与第一方向相反的第二方向，避免排水泵在第一方向上堵塞时仍按照第一方向继续运转，在第一方向堵塞的情况下切换为按照第二方向运转，既能确保较高的排水效率，又不会使电机升温，而且避免排水泵产生很大噪音，减少了排水泵单向堵塞情况下的资源浪费。
在本申请的一些实施例中，在排水泵在第一方向上堵塞时电机切换为按照第二方向运转，可以一直按照第二方向运转直至排水结束。
由于一直按照第二方向运转，头发或线头等杂物容易沿着第二方向缠绕在排水泵的叶轮上，阻碍叶轮沿第二方向运转，甚至导致排水泵的叶轮在第二方向上堵塞。而排水泵在第一方向上堵塞，经过电机按照第二方向转动一定时长之后，沿第一方向缠绕在排水泵的叶轮上的杂物，可能会沿第二方向缠绕从叶轮上解除下来。
因此在本申请的另一些实施例中，还可以在排水泵在第一方向上堵塞并将电机的运转方向切换至第二方向时开始计时，将计时的时长与第二预设时长进行比较，若确定出计时的时长小于第二预设时长，则控制电机继续按照第二方向运转。若确定电机按照第二方向转动的时长大于或等于第二预设时长，则再次控制电机改变转动方向，即控制电机按照第一方向转动。在控制电机按照第一方向转动的过程中，通过步骤102和103的操作确定当前排水泵在第一方向上是否仍然堵塞。若确定当前排水泵在第一方向上仍堵塞，则再次控制电机按照第二方向转动。若确定当前排水泵在第一方向上不再堵塞，则再按照步骤101的方式每隔第一预设时长控制排水泵的电机改变转动方向。
由于排水泵在第一方向上堵塞，是因为电机按照第一方向转动第一预设时长造成的，也就是说杂物是经过小于或等于第一预设时长的时间沿第一方向缠绕在排水泵的叶轮上的。若想使得杂物沿与第一方向相反的第二方向缠绕以从叶轮上解除下来，则在叶轮转速相同的前提下至少需要第一预设时长的时间才能达到杂物反向缠绕解除下来的目的。因此本申请实施例设置上述第二预设时长大于或等于第一预设时长，以使杂物能反向缠绕解除下来，提高疏通排水泵在第一方向上堵塞的概率。第二预设时长可以为1min、3min或5min等。本申请实施例并不限 制第二预设时长的具体取值，实际应用中可根据需求进行设定。
在上述控制电机按照第二方向运转的过程中，同样按照步骤102和103的操作来判断排水泵在第二方向上是否堵塞。若确定出排水泵在第二方向上未堵塞，则继续控制电机按照第二方向运转直至排水结束。或者在确定出排水泵在第二方向上未堵塞时，在确定电机按照第二方向运转的时长达到第二预设时长时，再控制电机按照第一方向运转。若确定出排水泵在第二方向上也堵塞了，则再次控制电机按照第一方向转动，并通过步骤102和103的操作来判断排水泵在第一方向上是否仍堵塞。若排水泵在第一方向上不再堵塞，则控制电机按照第一方向一直运转直至结束，或者，控制电机按照第一方向运转第二预设时长后再次控制电机按照第二方向运转。
若确定出排水泵在第一方向上仍堵塞，则表明排水泵在第一方向和第二方向上均堵塞了，可以控制电机停机，并发出用于指示排水泵堵塞的指示信息。或者，可以在确定排水泵在第一方向上堵塞与确定排水泵在第二方向上堵塞的间隔时间小于第三预设时长时，将排水泵在第一方向和第二方向上均堵塞的连续次数加一。将当前的连续次数与预设次数进行比较，若确定当前的连续次数小于预设次数，则继续按照上述方式控制电机运转。若确定当前的连续次数大于或等于预设次数，则控制电机停机，并发出用于指示排水泵堵塞的指示信息。
上述第三预设时长可以为10s、20s、30s等。预设次数可以为3或5等。本申请实施例并不限制第三预设时长及预设次数的具体取值，实际应用中可根据需求设定。
家电设备可以通过点亮预设的指示灯来指示排水泵堵塞。或者，家电设备可以通过播放用于提示排水泵堵塞的语音信息。或者，家电设备可以通过显示屏显示用于指示排水泵堵塞的文本信息。
为了便于理解本申请实施例提供的控制方法，下面结合附图进行说明。如图2所示，S1：控制排水泵的电机按照第一方向转动进行排水。S2：根据当前的电机运行参数，确定排水泵在第一方向上是否堵塞，如果是，则执行步骤S3，如果否，则执行步骤S9。S3：控制电机按照第二方向转动，第二方向与第一方向相反。S4：根据当前的电机运行参数，确定排水泵在第二方向上是否堵塞，如果是，则执行步骤S5，如果否，则执行步骤S8。S5：将排水泵在第一方向和第二方向上均堵塞 的连续次数加一。S6：判断加一操作后的连续次数是否等于预设次数，如果是，则执行步骤S7，如果否，则执行步骤S1。S7：控制电机停机，发出用于提示排水泵堵塞的提示信息。S8：确定电机在第二方向上运转的时长是否达到第二预设时长，如果是，则执行步骤S1，如果否，则执行步骤S3。S9：确定电机在第一方向上运转的时长是否达到第一预设时长，如果是，则执行步骤S3，如果否，则执行步骤S1。
在本申请实施例中，排水过程中控制排水泵的电机交替地进行正转和反转，这样杂物沿着排水泵的叶轮转动的一个方向缠绕在叶轮上后，电机转动方向改变，能够使缠绕在叶轮上的杂物反向缠绕从叶轮上解除下来，能够有效减少排水泵堵塞的情况。而且在电机运行过程中实时依据电机运行参数来确定排水泵在当前方向上是否发生了堵塞，并在确定发生堵塞时控制电机切换为反方向运转，避免排水泵在某个方向上堵塞时仍按照该方向继续运转，在排水泵单向堵塞的情况下，既能确保较高的排水效率，又不会使电机升温，而且避免排水泵产生很大噪音，减少了排水泵单向堵塞情况下的资源浪费。而且在排水泵单向堵塞的情况下，控制电机反方向运转，能够解除缠绕在排水泵的叶轮上的杂物，有助于疏通排水泵单向堵塞的情况。

  6. 根据权利要求1-3任一项所述的方法，其特征在于，所述根据当前的电机运行参数，确定所述排水泵在第一方向上是否堵塞，包括：
    根据当前的电机运行参数包括的相电流大于预设电流阈值，确定所述排水泵在第一方向上堵塞；或者，
    根据当前的电机运行参数包括的运行功率大于预设功率阈值，确定所述排水泵在第一方向上堵塞；或者，
    根据当前的电机运行参数包括的转速小于预设转速阈值，确定所述排水泵在第一方向上堵塞；或者，
    根据当前的电机运行参数包括的转矩大于预设转矩阈值，确定所述排水泵在第一方向上堵塞。
  7. 一种排水泵控制装置，其特征在于，包括：
    转动方向控制模块，用于每隔第一预设时长控制排水泵的电机改变转动方向；
    参数采集模块，用于实时采集电机转动过程中的电机运行参数；
    堵塞确定模块，用于根据当前的电机运行参数，确定所述排水泵在第一方向上是否堵塞，所述第一方向为当前转动方向；根据所述排水泵在所述第一方向上堵塞，控制所述电机按照第二方向转动，所述第二方向与所述第一方向相反。
  8. 根据权利要求7所述的装置，其特征在于，
    所述转动方向控制模块，还用于确定所述电机按照第二方向转动的时长达到第二预设时长，所述第二预设时长大于或等于所述第一预设时长；控制所述电机按照所述第一方向转动；
    所述堵塞确定模块，还用于确定所述排水泵在所述第一方向上不再堵塞，通过所述转动方向控制模块每隔第一预设时长控制排水泵的电机改变转动方向；确定所述排水泵在所述第一方向上仍堵塞，则所述控制所述电机按照第二方向转动。
  9. 一种家电设备，包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，其特征在于，所述处理器运行所述计算机程序以实现如权利要求1-6任一项所述的方法。
