具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图1-4描述本公开实施例的洗涤设备及其进水控制方法和滚筒洗衣机。
图1是根据本公开一个实施例的洗涤设备的进水控制方法的流程图。如图1所示，该洗涤设备的进水控制方法包括以下步骤：
S1，控制洗涤设备进水。
在该实施例中，用户在设置好洗衣模式(包含洗涤过程和/或漂洗过程)，并运行该洗衣模式对应的洗衣程序时，洗涤设备自动进入供水步骤，洗涤设备的进水阀打开，以向洗涤设备供水。
作为一个示例，在向洗涤设备供水前，可控制洗涤设备的显示屏或者洗涤设备的控制终端的显示屏显示是否进行虹吸检测的提示，如弹出滑动箭头，若需要进行虹吸检测，则可从左向右滑动箭头以确定进行虹吸检测，若不需要监测，则可按压“取消”按键。若在提示显示后的预设时间如5-10s内未检测到确认指令或取消指令，则可默认进行虹吸检测，并控制进水阀打开以供水。
S2，每隔第一预设时间获取洗涤设备的第一水位变化值。
作为一个示例，当进水阀打开后，可通过压力式水位传感器检测水位上升数据，该水 位上升数据可为频率数值，水位上升数据为正说明水位上升，水位上升数据为负说明水位下降，进而可每隔第一预设时间(如1min)获取洗涤设备的第一水位变化值即水位上升数据。可选地，第一预设时间可在显示屏设置栏里进行设置，其设置范围可为30s-90s，如还可以设置第一预设时间为30s。
S3，根据第一水位变化值控制洗涤设备的进水过程。
在本公开的一个实施例中，根据第一水位变化值控制洗涤设备的进水过程，包括：基于第一水位变化值确定水位上升量大于第一预设值，控制洗涤设备保持正常进水；基于第一水位变化值确定水位下降量大于第二预设值，执行虹吸处理。
其中，第一预设值、第二预设值可根据洗涤设备的进水流量、第一预设时间进行设置。
举例而言，如图2所示，假定第一预设时间为1min，若在第一个检测周期即第一个第一预设时间1min内，基于每个第一水位变化值均确定水位上升量大于第一预设值，如频率数值均大于30Hz，说明水位一直在上升，则控制进水阀在第二个检测周期持续打开，以控制洗涤设备保持正常进水，并进行下一个检测周期的判断，同时还可控制显示屏显示“供水正常”信息。若在第一个检测周期即第一个第一预设时间1min内，基于每个第一水位变化值确定水位下降量大于第二预设值至少一次，如频率数值小于-2Hz一次，此时可认为洗涤设备内产生虹吸现象或漏水故障，则执行虹吸处理。
在本公开的一个实施例中，根据第一水位变化值控制洗涤设备的进水过程，还包括：基于水位变化值确定水位下降量小于等于第二预设值或水位上升量小于等于第一预设值且累计达到N1次，控制洗涤设备停止进水并保持第二预设时间，获取第二水位变化值，其中N1是大于等于1的自然数，如N1为3；基于第二水位变化值确定水位下降量大于或等于第三预设值，执行虹吸处理。
举例而言，如图2所示，假定第一预设时间为1min。若在第一个检测周期内，累积基于第一水位变化值确定水位上升量小于等于第一预设值或水位下降量小于等于第二预设值达3次，如频率数值大于等于-2Hz且小于等于30Hz达3次，则可控制进水阀关闭2min。若在第二预设时间即2min内基于第二水位变化值确定水位下降量大于等于第三预设值，如频率数值下降累积达到5Hz，此时可认为洗涤设备内产生虹吸现象或漏水故障，则执行虹吸处理。
需要说明的是，如果水位上升量小于或等于第一预设值或水位下降量小于等于第二预设值的情况连续出现2次后，第三次水位上升量大于第一预设值，则可将计数值清0，重新计数。
在本公开的一个实施例中，执行虹吸处理包括：控制洗涤设备停止进水并保持第三预设时间，获取第三水位变化值；基于第三水位变化值确定水位下降量大于或等于第四预设 值且累计达到N2次，控制洗涤设备发出第一警示信息，其中N2是大于等于1的自然数。
举例而言，假定第三预设时间为3min。当洗涤设备内产生虹吸现象或漏水故障时，可控制洗涤设备进水阀关闭3min，并在第一预设时间(如1min)内，基于第三水位变化值确定水位下降量大于第四预设值，则计当前检测次数加1。如果连续N2(如3)次检测到第三水位变化值大于第四预设值，则控制洗涤设备内的蜂鸣器发出虹吸报警信息，并可在显示屏上显示“存在虹吸”信息，以进行虹吸提示。
在本公开的一个实施例中，基于第二水位变化值确定水位下降量小于第三预设值，控制洗涤设备恢复进水，并保持第四预设时间，获取第四水位变化值；基于第四水位变化值确定水位上升量大于第一预设值，控制洗涤设备保持正常进水；基于第四水位变化值确定水位下降量大于第二预设值，控制洗涤设备发出第一警示信息；基于第四水位变化值确定水位下降量大于等于第一预设值或上升量小于等于第二预设值，控制洗涤设备发出第二警示信息。
在该实施例中，若在第二预设时间(如2min)内，基于第二水位变化值确定水位下降量小于第三预设值，可认为没有发生虹吸现象，则控制进水阀打开第四预设时间(如4min)，并进行下一个检测周期的水位检测，即每隔第一预设时间(如1min)检测洗涤设备的第四水位变化值。若在第一个检测周期内，检测到第四水位变化值为正值且大于第一预设值，则控制进水阀在第二个检测周期持续打开，并进行下一个检测周期的判断，同时还可控制显示屏显示“供水正常”信息。若在第一个检测周期内，检测到第四水位变化值为负值且其数值大于第二预设值，可认为洗涤设备内产生虹吸现象，则控制进水阀关闭，并控制洗涤设备发出第一提示信息如显示屏显示“存在虹吸”，以进行虹吸提示。若在第一个检测周期内，累积检测到第四水位变化值为负值且其数值小于第二预设值或检测到第四水位变化值为正值且小于第一预设值达3次，则可控制进水阀关闭，控制洗涤设备的排水阀打开，并控制洗涤设备发出第二提示信息如在显示屏显示故障码E10，以进行故障提示。
作为一个示例，也可根据检测的频率数值确定水位的变化情况，如上升、下降，进而根据上升次数与检测到的总频率数值数的比值对进水阀进行控制，比例为100％说明水位持续上升。例如，每隔一定时间获取上述比值，若比值大于第一预设比值，则控制进水阀持续打开；若比值大于或等于第二预设比值且小于或等于第一预设比值，则控制进水阀关闭一定时间，并获取该时间内的水位变化情况，根据该水位变化情况对进水阀进行进一步控制；若比值小于第二预设比值，说明发生虹吸或漏水故障，控制进水阀关闭一定时间，并获取该时间内的水位变化情况，根据该水位变化情况对进水阀进行进一步控制。
根据本公开实施例的洗涤设备的进水控制方法，可对洗涤设备在进水过程中出现的故障情况和虹吸现象进行精准检测，便于提高售后维修工作的便利性。
图3是根据本公开一个实施例的洗涤设备的结构框图。如图3所示，该洗涤设备10包括控制模块100和获取模块200。
其中，控制模块100，用于控制洗涤设备进水。
获取模块200，用于每隔第一预设时间获取洗涤设备的第一水位变化值。
控制模块100，还用于根据第一水位变化控制洗涤设备的进水过程。
在本公开的一个实施例中，控制模块100具体用于：基于第一水位变化值确定水位上升量大于第一预设值，控制洗涤设备保持正常进水；基于第一水位变化值确定水位下降量大于第二预设值，执行虹吸处理。
作为一个示例，如图2所示，若在第一个检测周期即第一个第一预设时间1min内，检测到第一水位变化值为正值且大于第一预设值，控制模块100则控制进水阀在第二个检测周期持续打开，以控制洗涤设备保持正常进水，并进行下一个检测周期的判断，同时还可控制显示屏显示“供水正常”信息。若在第一个检测周期即第一个第一预设时间1min内，检测到第一水位变化值为负值且其数值大于第二预设值，此时可认为洗涤设备内产生虹吸现象或漏水故障，则通过控制模块100执行虹吸处理。
在本公开的一个实施例中，控制模块100具体还用于：基于水位变化值确定水位下降量小于等于第二预设值或水位上升量小于等于第一预设值且累计达到N1次，控制洗涤设备停止进水并保持第二预设时间，获取第二水位变化值，其中N1是大于等于1的自然数；基于第二水位变化值确定水位下降量大于或等于第三预设值，执行虹吸处理。
具体地，如图2所示，若在第一个检测周期内，累积检测到第一水位变化值为负值且其数值小于第二预设值或检测到第一水位变化值为正值且小于第一预设值达3次，则控制模块100可控制进水阀关闭第二预设时间(如2min)，并检测到第二预设时间即2min内的第二水位变化值为负值且其数值大于或等于第三预设值，此时可认为洗涤设备内产生虹吸现象或漏水故障，并通过控制模块100执行虹吸处理。
在本公开的一个实施例中，控制模块100具体还用于：控制洗涤设备停止进水并保持第三预设时间，获取第三水位变化值；基于第三水位变化值确定水位下降量大于或等于第四预设值且累计达到N2次，控制洗涤设备发出第一警示信息，其中N2是大于等于1的自然数。
