Description

用于洗涤设备的杀菌控制方法 技术领域
本发明属于洗涤设备技术领域，具体提供一种用于洗涤设备的杀菌控制方法。
背景技术
随着科技的不断进步以及人们生活水平的不断提高，洗涤设备成为了每个家庭必不可少的家用电器。洗涤设备主要包括洗衣机、洗鞋机和洗碗机等。
以洗衣机为例，洗衣机使用一段时间后，洗衣机内会有污垢残存，从而会滋生螨虫、霉菌、细菌等。为了保证洗衣机的洗涤卫生，避免滋生螨虫、霉菌、细菌等对洗涤的衣物产生污染，需要定期对洗衣机进行除菌处理。目前，大多的数洗衣机都还不具备自动除菌功能，大多数用户都是根据经验或者使用习惯来决定何时对洗衣机进行杀菌，比较盲目，因为用户很难准确地判断洗衣机的当前状况是否需要杀菌，如果当前洗衣机需要杀菌而没能及时地对洗衣机进行杀菌，则会造成衣物感染，反之，如果当前洗衣机不需要杀菌而对洗衣机进行杀菌了，则又会造成能源浪费。
公开号为CN109423814A的专利申请文件公开了一种洗衣机的除菌控制方法，除菌控制方法包括以下步骤：在洗衣机开机后，获取洗衣机的洗涤周期的计数情况，其中，洗衣机每执行一次洗涤程序，洗涤周期的计数加一；根据洗涤周期的计数情况判断是否满足除菌条件；如果满足除菌条件，则控制洗衣机调用除菌程序，并锁定洗衣机的洗涤程序，以及在接收到用户的除菌指令后控制洗衣机执行除菌程序。也就是说，根据洗衣机的洗涤次数来判断是否满足除菌条件。然而，这种控制方法的判断条件比较单一，判断结果不够准确。
因此，本领域需要一种用于洗涤设备的杀菌控制方法来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有洗涤设备采用根据洗涤次数来判断是否进行杀菌的方法，判断结果不够准确的问题，本发明提供了一种用于洗涤设备的杀菌控制方法，获取待洗涤物的脏污程度；判断所述待洗涤物的脏污程度是否大于预设脏污值；如果所述待洗涤物的脏污程度大于所述预设脏污值，则使脏污次数加1；将所述脏污次数与预设值进行比较；根据比较结果，选择性地使所述洗涤设备执行杀菌操作。
在上述杀菌控制方法的优选技术方案中，“根据比较结果，选择性地使所述洗涤设备执行杀菌操作”的步骤具体包括：如果所述脏污次数达到所述预设值，则使所述洗涤设备执行杀菌操作。
在上述杀菌控制方法的优选技术方案中，“根据比较结果，选择性地使所述洗涤设备执行杀菌操作”的步骤还包括：如果所述脏污次数未达到所述预设值，则不使所述洗涤设备执行杀菌操作。
在上述杀菌控制方法的优选技术方案中，所述预设值包括第一预设值和第二预设值，其中，第一预设值小于第二预设值，所述杀菌控制方法还包括：获取环境温度；将所述环境温度与预设温度进行比较；当所述环境温度高于所述预设温度时，“将所述脏污次数与预设值进行比较”的步骤具体包括：将所述脏污次数与所述第一预设值进行比较；当所述环境温度低于或者等于所述预设温度时，将所述脏污次数与预设值进行比较”的步骤具体包括：将所述脏污次数与所述第二预设值进行比较。
在上述杀菌控制方法的优选技术方案中，所述洗涤设备包括杀菌装置，“使所述洗涤设备执行杀菌操作”的步骤具体包括：使所述杀菌装置运行。
在另一方面，本发明还提供了另一种用于洗涤设备的杀菌控制方法，所述杀菌控制方法包括：获取待洗涤物的脏污程度；判断所述待洗涤物的脏污程度是否大于预设脏污值；如果所述待洗涤物的脏污程度大于所述预设脏污值，则使脏污次数加1；获取洗涤次数；根据所述脏污次数和所述洗涤次数，选择性地使所述洗涤设备执行杀菌操作。
在上述杀菌控制方法的优选技术方案中，“根据所述脏污次数和所述洗涤次数，选择性地使所述洗涤设备执行杀菌操作”的步骤具体包括：如果所述脏污次数达到第一预设值，并且，所述洗涤次数达到第二预设值，则使所述洗涤设备执行杀菌操作，其中，所述第一预设值小于所述第二预设值。
在上述杀菌控制方法的优选技术方案中，“根据所述脏污次数和所述洗涤次数，选择性地使所述洗涤设备执行杀菌操作”的步骤还包括：如果所述脏污次数达到第三预设值，则使所述洗涤设备执行杀菌操作，其中，所述第三预设值大于所述第一预设值且小于所述第二预设值。
在上述杀菌控制方法的优选技术方案中，“根据所述脏污次数和所述洗涤次数，选择性地使所述洗涤设备执行杀菌操作”的步骤还包括：如果所述洗涤次数达到第四预设值，则使所述洗涤设备执行杀菌操作，其中，所述第四预设值大于所述第二预设值。
在上述杀菌控制方法的优选技术方案中，所述第一预设值包括第一主预设值和第一辅预设值，所述第一主预设值大于所述第一辅预设值，所述第二预设值包括第二主预设值和第二辅预设值，所述第二主预设值大于所述第二辅预设值，所述杀菌控制方法还包括：获取环境温度；将所述环境温度与预设温度进行比较；当所述环境温度低于所述预设温度时，采用所述第一主预设值和所述第二主预设值为判断基础；当所述环境温度高于或者等于所述预设温度时，采用所述第一辅预设值和所述第二辅预设值为判断基础。
本领域技术人员能够理解的是，在本发明的优选技术方案中，本发明的洗涤设备在每次洗涤待洗涤物时，都要获取待洗涤物的脏污程度，然后判断待洗涤物的脏污程度是否大于预设脏污值，当待洗涤物的脏污程度大于预设脏污值时，使脏污次数加1，然后将脏污次数与预设值进行比较来判断洗涤设备是否满足杀菌条件，进而选择是否使洗涤设备执行杀菌操作。与公开号为CN109423814A的专利申请文件中根据洗涤次数来判断是否满足除菌条件的方法相比，本发明根据每次洗涤的待洗涤物的脏污程度来确定脏污次数，然后通过脏污次数来判断洗涤设备是否满足杀菌条件的方法更加准确。具体而言，每次被洗涤的待洗涤物的脏污程度对洗涤设备内的脏污情况的影响是不同的，洗涤设备内的脏污程 度越严重越容易滋生细菌，以待洗涤物是衣物，洗涤次数是20次为例，第一种情形，这20次洗涤的衣物都是比较干净的，像夏天的时候，因为经常出汗，可能衣物每天都要洗一次，但其实这时候的衣物是比较干净的，对洗衣机内的脏污情况影响比较小，可以忽略不计；第二种情形，这20次洗涤的衣物都是比较脏的，像冬天的时候，衣物穿好几天后才会洗一次，这时候的衣物是比较脏的，对洗衣机内的脏污情况影响也比较大；针对上述的这两种情形，只有在第二种情形下才需要对洗衣机进行杀菌，因此，只是根据洗涤次数来判断是否满足杀菌条件，显然判断结果是不够准确的，根据脏污次数(每次洗涤的待洗涤物的脏污程度和洗涤次数的综合数据)来判断洗涤设备是否满足杀菌条件的方法更加准确。
进一步地，预设值包括第一预设值和第二预设值，第一预设值小于第二预设值，杀菌控制方法还包括：获取环境温度，将环境温度与预设温度进行比较，当环境温度高于预设温度时，“将脏污次数与预设值进行比较”的步骤具体包括：将脏污次数与第一预设值进行比较；当环境温度低于或者等于预设温度时，将脏污次数与预设值进行比较”的步骤具体包括：将脏污次数与第二预设值进行比较。通过设置两个大小不同的预设值，当环境温度高时，采用较小的预设值，以提高杀菌频率，能够进一步提高判断的准确性，及时地对洗涤设备进行杀菌。
更一步地，“使杀菌装置运行”的步骤具体包括：在洗涤设备完成洗涤作业之后，再使杀菌装置运行。当用户将待洗涤物从洗涤设备内取出后才表示洗涤设备执行完洗涤作业，通过这样的设置，既能够保证洗涤程序顺利地进行，也能够避免对待洗涤物造成损害。
此外，本发明还提供了另一种优选的技术方案，在该优选技术方案中，洗涤设备在每次洗涤待洗涤物时，都要获取待洗涤物的脏污程度，然后判断待洗涤物的脏污程度是否大于预设脏污值，当待洗涤物的脏污程度大于预设脏污值时，使脏污次数加1；此外，还要获取洗涤设备的洗涤次数，洗涤设备每执行一次洗涤程序，洗涤次数加1；然后根据脏污次数和洗涤次数来综合判断洗涤设备是否满足杀菌条件，进而选择是否使洗涤设备执行杀菌操作。与公开号为CN109423814A的专利申请文件中仅仅根据洗涤次数来判断是否满足除菌条件的方法相比，本发明通过脏污次数和洗涤次数来综合判断洗涤设备是否满足杀菌条件的方法更 加准确。具体原因与前一种杀菌控制方法相似，因此不再赘述。
进一步地，“根据脏污次数和洗涤次数，选择性地使洗涤设备执行杀菌操作”的步骤具体包括：(条件一)如果脏污次数达到第一预设值且洗涤次数达到第二预设值，则使洗涤设备执行杀菌操作；(条件二)如果脏污次数达到第三预设值，则使洗涤设备执行杀菌操作，其中，第三预设值大于第一预设值且小于第二预设值。通过设置两个判断条件，能够保证洗涤设备能够及时地进行杀菌。具体而言，示例性地，洗涤设备是洗衣机，待洗涤物是衣物，第一预设值是10次，第二预设值是20次，第三预设值是15次，一般情况下，有时洗涤的衣物是比较干净的，有的时洗涤的衣物是比较脏的，当脏污次数达到10次且洗涤次数达到20次时，满足条件一，可以对洗衣机进行杀菌，但是，如果大部分时候洗涤的衣物都是比较脏的，脏污次数已经达到15次，但是洗涤次数还没有达到20次，在这种情形下，其实洗衣机内的脏污情况已经比较严重了，就需要对洗衣机进行杀菌了，但是由于洗涤次数还没有达到20次，不满足条件一，如果只设置了条件一的话，就无法使洗衣机执行杀菌操作，因此，通过设置条件二，虽然洗涤次数还没有达到20次，但只要脏污次数达到15次，就使洗衣机执行杀菌操作，从而能够保证洗衣机能够及时地进行杀菌。
进一步地，“根据脏污次数和洗涤次数，选择性地使洗涤设备执行杀菌操作”的步骤具体包括：(条件一)如果脏污次数达到第一预设值且洗涤次数达到第二预设值，则使洗涤设备执行杀菌操作；(条件二)如果洗涤次数达到第四预设值，则使洗涤设备执行杀菌操作，其中，第二预设值大于第一预设值且小于第四预设值。通过设置两个判断条件，能够保证洗涤设备能够及时地进行杀菌。具体而言，示例性地，洗涤设备是洗衣机，待洗涤物是衣物，第一预设值是10次，第二预设值是20次，第四预设值是25次，一般情况下，有时洗涤的衣物是比较干净的，有的时洗涤的衣物是比较脏的，当脏污次数达到10次且洗涤次数达到20次时，满足条件一，可以对洗衣机进行杀菌，但是，如果大部分的时候洗涤的衣物都是比较干净的，导致脏污次数一直没有达到10次，但是洗涤次数已经达到了25次，在这种情形下，其实洗衣机内的脏污情况已经比较严重了，就需要对洗衣机进行杀菌了，但是由于脏污次数还没有达 到10次，不满足条件一，如果只有条件一的话，就无法使洗衣机执行杀菌操作，因此，通过设置条件二，虽然脏污次数还没有达到10次，但只要洗涤次数达到25次，就使洗衣机执行杀菌操作，从而能够保证洗衣机能够及时地进行杀菌。
再进一步地，第一预设值包括第一主预设值和第一辅预设值，第一主预设值大于第一辅预设值，第二预设值包括第二主预设值和第二辅预设值，第二主预设值大于第二辅预设值，杀菌控制方法还包括：获取环境温度；将环境温度与预设温度进行比较；当环境温度低于预设温度时，采用第一主预设值和第二主预设值为判断基础；当环境温度高于或者等于预设温度时，采用第一辅预设值和第二辅预设值为判断基础。通过将第一预设值和第二预设值分别设置两个大小不同的主预设值和辅预设值，当环境温度高于或者等于预设温度时，采用较小的辅预设值，以提高杀菌频率，能够进一步提高判断的准确性，及时地对洗涤设备进行杀菌。

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，下面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，虽然下面这些实施方式是结合洗衣机来进行说明的，但是，本发明依然适用于其他的洗涤设备，例如， 洗干一体机、洗鞋机等，这种应用对象的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
基于背景技术指出的现有洗衣机采用根据洗涤次数来判断是否进行杀菌的方法，判断结果不够准确的问题。本发明提供了一种用于洗衣机的杀菌控制方法，旨在提高洗衣机的判断准确性。
本发明提供了两种用于洗衣机的杀菌控制方法，下面参照图1和图2来详细地介绍第一种用于洗衣机的杀菌控制方法，图1是本发明的第一种用于洗衣机的杀菌控制方法的流程图；图2是本发明的第一种用于洗衣机的杀菌控制方法的实施例的流程图。
如图1所示，本发明的第一种用于洗衣机的杀菌控制方法包括以下步骤：
S1：获取待洗涤物的脏污程度；
S2：判断待洗涤物的脏污程度是否大于预设脏污值；
S3：如果待洗涤物的脏污程度大于预设脏污值，则使脏污次数加1；
S4：将脏污次数与预设值进行比较；
S5：根据比较结果，选择性地使洗衣机执行杀菌操作。
以待洗涤物是衣物为例，本发明的洗衣机在每次洗涤衣物时，都要获取衣物的脏污程度，然后判断衣物的脏污程度是否大于预设脏污值，当衣物的脏污程度大于预设脏污值时，说明衣物的脏污程度比较严重，对洗衣机内的脏污程度影响较大，在这种情形下，使脏污次数加1，洗衣机的控制器内一般都设置有计数器，使计数器加1即可，然后将脏污次数与预设值进行比较来判断洗衣机是否满足杀菌条件，进而选择是否使洗衣机执行杀菌操作。
与公开号为CN109423814A的专利申请文件中根据洗涤次数来判断是否满足除菌条件的方法相比，本发明通过脏污次数来判断洗衣机是否满足杀菌条件的方法更加准确，其中，脏污次数相当于洗衣机每次洗涤的衣物的脏污程度和洗涤次数的综合数据，也就是说，本发明是通过洗衣机每次洗涤的衣物的脏污程度和洗涤次数来综合判断洗衣机是否满足杀菌条件的，能够提高判断结果的准确性。
具体而言，每次被洗涤的衣物的脏污程度对洗衣机内的脏污情 况的影响是不同的，洗衣机内的脏污程度越严重越容易滋生细菌，以洗涤次数是20次为例，第一种情形，这20次洗涤的衣物都是比较干净的，像夏天的时候，因为经常出汗，可能衣物每天都要洗一次，但其实这时候的衣物是比较干净的，对洗衣机内的脏污情况影响比较小，可以忽略不计；第二种情形，这20次洗涤的衣物都是比较脏的，像冬天的时候，衣物穿好几天后才会洗一次，这时候的衣物是比较脏的，对洗衣机内的脏污情况影响也比较大；针对上述的这两种情形，只有在第二种情形下才需要对洗衣机进行杀菌，因此，只是根据洗涤次数来判断是否满足杀菌条件，显然判断结果是不够准确的。
需要说明的是，在实际应用中，可以通过采集洗涤水的浊度来确定待洗涤物的脏污程度，例如，待洗涤物是衣物，可以在洗衣机的洗涤桶内安装浊度传感器，浊度传感器能够与洗衣机的控制器进行通信，在洗涤衣物时，可以通过浊度传感器采集洗涤水的浊度信息，并将采集到的浊度信息传输给控制器，控制器洗涤水的浊度信息来判断衣物的脏污程度，或者，还可以通过采集待洗涤物的图像信息来确定待洗涤物的脏污程度，例如，待洗涤物是鞋子，洗涤设备是洗鞋机，当然，有的洗衣机也具备洗鞋功能，可以在洗鞋机的箱体内设置图像采集装置(例如摄像头等)，图像采集装置能够与洗鞋机的控制器进行通信，在洗涤鞋子时，可以通过图像采集装置采集鞋子的图像信息，并将采集到的图像信息传输给控制器，控制器通过对鞋子的图像信息进行分析来判断鞋子的脏污程度，等等，这种对获取待洗涤物的脏污程度的具体确定方法的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
此外，还需要说明的是，可以在洗衣机的控制器内预设一个浊度值与脏污值对照表，采集到洗涤水的浊度后通过浊度值与脏污值对照表来确定待洗涤物的脏污程度。
此外，还需要说明的是，在采集到洗涤水的浊度后，可以不将浊度值换算成脏污值，可以直接将采集到的洗涤水的浊度直接与预设浊度值进行比较，即，用洗涤水的浊度代替待洗涤物的脏污程度，用预设浊度值代替预设脏污值，如果洗涤水的浊度大于预设浊度值，说明待洗涤物的脏污程度大于预设脏污值，使脏污次数加1，这种灵活 地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
下面以根据洗涤水的浊度来确定待洗涤物的脏污程度为例，并结合一个具体的实施例来详细地介绍本发明的第一种用于洗衣机的杀菌控制方法。
如图2所示，本实施例的杀菌控制方法包括以下步骤：
S100：获取洗涤水的浊度；
S200：根据洗涤水的浊度确定待洗涤物的脏污程度；
S300：判断待洗涤物的脏污程度是否大于预设脏污值；
S400：如果待洗涤物的脏污程度大于预设脏污值，则使脏污次数加1；
S500：将脏污次数与预设值进行比较；
S601：如果脏污次数达到预设值，则使洗衣机执行杀菌操作；
S602：如果脏污次数未达到预设值，则不使洗衣机执行杀菌操作。
以待洗涤物是衣物，预设值是15次为例。
在洗衣机对衣物进行洗涤时，通过浊度传感器采集洗涤水的浊度，然后根据洗涤水的浊度确定衣物的脏污程度，将衣物的脏污程度与预设脏污值进行比较，当衣物的脏污程度大于预设脏污值时，说明衣物比较脏，对洗衣机内的脏污情况影响较大，因此，使脏污次数加1，反之，当衣物的脏污程度小于或者等于预设脏污值时，说明衣物比较干净，对洗衣机内的脏污情况影响较小，可以忽略不计，因此，使脏污次数保持不变；将脏污次数与预设值(15次)进行比较，当脏污次数达到15次时，说明洗衣机满足杀菌条件，此时，使洗衣机执行杀菌操作；当脏污次数未达到15次时，说明洗衣机不满足杀菌条件，则不使洗衣机执行杀菌操作。
需要说明的是，“使洗衣机执行杀菌操作”可以是使洗衣机自动启动杀菌模式以对洗衣机进行杀菌，示例性地，洗衣机包括杀菌装置，当满足杀菌条件时，洗衣机可以自动使杀菌装置运行，以对洗衣机进行杀菌；或者，“使洗衣机执行杀菌操作”也可以是使洗衣机发出提示，以告知用户洗衣机需要进行杀菌，示例性地，洗衣机包括 语音播放器，当满足杀菌条件时，使语音播放器播放语音，以告知用户需要对洗衣机进行杀菌了，或者也可以使洗衣机的控制面板显示文字，再或者使洗衣机上的指示灯显示报警颜色等等，如果洗衣机有杀菌装置，用户可以直接启动杀菌装置对洗衣机进行杀菌，如果洗衣机没有杀菌装置，用户需要手动添加杀菌剂等对洗衣机进行杀菌。
优选地，预设值包括第一预设值和第二预设值，第一预设值小于第二预设值，本实施例的杀菌控制方法还包括：当环境温度高于预设温度时，“将脏污次数与预设值进行比较”的步骤具体包括：将脏污次数与第一预设值进行比较；当环境温度不高于预设温度时，将脏污次数与预设值进行比较”的步骤具体包括：将脏污次数与第二预设值进行比较。
即，预设值包括两个大小不同的值，根据环境温度来选择其中一个预设值与脏污次数进行比较。示例性地，预设温度为25度，第一预设值为10次，第二预设值为15次，当环形温度大于25度时，说明环境温度比较高，洗衣机内易滋生细菌，在这种情形下，采用第一预设值，即，当脏污次数达到10次时，就使洗衣机进行杀菌；当环形温度小于或者等于25度时，说明环境温度比较低，洗衣机内不易滋生细菌，在这种情形下，采用第二预设值，即，当脏污次数达到15次时，再使洗衣机进行杀菌。
优选地，本发明的洗衣机包括杀菌装置，“使洗衣机执行杀菌操作”的步骤具体包括：使杀菌装置运行。当洗衣机满足杀菌条件时，洗衣机可以自动使杀菌装置运行以对洗衣机进行杀菌。其中，杀菌装置是电解水杀菌装置，通过电解水杀菌装置能够有效地将洗衣机内的污垢清除，以对洗衣机进行杀菌。当然，也可以将杀菌装置设置为其他类型的杀菌装置，例如杀菌剂或者杀菌液投放装置、紫外线杀菌装置、臭氧杀菌装置等，这种对杀菌装置的具体类型的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
需要说明的是，当杀菌装置运行后，脏污次数清零重新开始计数。
优选地，“使杀菌装置运行”的步骤具体包括：在洗衣机完成洗涤作业之后，再使杀菌装置运行。也就是说，当洗衣机满足杀菌 条件时，先暂时不使杀菌装置启动，等到洗衣机执行完洗涤作业之后再使杀菌装置运行。需要指出的是，当用户将衣物从洗衣机内取出后才表示洗衣机执行完洗涤作业，通过这样的设置，既能够保证洗涤程序顺利地进行，也能够避免对洗涤的衣物造成损害。在实际应用中，可以通过图像采集装置(例如摄像头)采集洗涤桶内的图像信息来判断洗涤桶内的衣物是否被取出，或者，也可以通过在洗涤桶上设置重量传感器采集重量信息来判断洗涤桶内的衣物是否被取出，等等。
优选地，“获取洗涤水的浊度”的步骤具体包括：以分段方式获取洗涤水的多个浊度值；计算多个浊度值的平均值；将平均值作为洗涤水的浊度。通过获取洗涤水的多个浊度值，以多个浊度值的平均值作为洗涤水的浊度，能够提高判断的准确性。示例性地，在洗衣机洗涤衣物时，每隔5秒钟获取一次洗涤水的浊度值，检测时间为10分钟，即共获取120个浊度值，将这120个浊度值的平均值作为洗涤水的浊度。当然，获取的浊度值的数量不限于上述情形中的120个，还可以是100个或者200个等，这种对获取的浊度值的具体数量的调整并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
下面参照图3和图4来详细地介绍第二种用于洗衣机的杀菌控制方法，图3是本发明的第二种用于洗衣机的杀菌控制方法的流程图；图4是本发明的第二种用于洗衣机的杀菌控制方法的实施例的流程图。
如图3所示，本发明的第二种用于洗衣机的杀菌控制方法包括以下步骤：
S1：获取待洗涤物的脏污程度；
S2：判断待洗涤物的脏污程度是否大于预设脏污值；
S3：如果待洗涤物的脏污程度大于预设脏污值，则使脏污次数加1；
S4：获取洗涤次数；
S5：根据脏污次数和洗涤次数，选择性地使洗衣机执行杀菌操作。
以待洗涤物是衣物为例，本发明的洗衣机在每次洗涤衣物时，都要获取衣物的脏污程度，然后判断衣物的脏污程度是否大于预设脏污值，当衣物的脏污程度大于预设脏污值时，说明衣物的脏污程 度比较严重，对洗衣机内的脏污程度影响较大，在这种情形下，使脏污次数加1，洗衣机的控制器内一般都设置有计数器，使计数器加1即可；此外，还要获取洗衣机的洗涤次数，洗衣机每执行一次洗涤程序，使计数器加1，脏污次数和洗涤次数可以采用两个计数器来分别计数，然后根据脏污次数和洗涤次数来综合判断洗衣机是否满足杀菌条件，进而选择是否使洗衣机执行杀菌操作。
与公开号为CN109423814A的专利申请文件中仅仅根据洗涤次数来判断是否满足除菌条件的方法相比，本发明通过脏污次数和洗涤次数来综合判断洗衣机是否满足杀菌条件的方法更加准确。
具体而言，洗衣机每次洗涤的衣物的脏污程度对洗衣机内的脏污情况的影响是不同的，洗衣机内的脏污程度越严重越容易滋生细菌，以洗涤次数是20次为例，第一种情形，这20次洗涤的衣物都是比较干净的，像夏天的时候，因为经常出汗，可能衣物每天都要洗一次，但其实这时候的衣物是比较干净的，对洗衣机内的脏污情况影响比较小；第二种情形，这20次洗涤的衣物都是比较脏的，像冬天的时候，衣物穿好几天后才会洗一次，这时候的衣物是比较脏的，对洗衣机内的脏污情况影响也比较大；针对上述的这两种情形，第二种情形下的洗衣机内的脏污情况肯定比第一种情形下的洗衣机内的脏污情况严重很多，如果都根据洗涤20次来判断是否满足杀菌条件，显然判断结果是不够准确的。
因此，本发明不仅获取了洗涤次数，还获取了衣物的脏污程度，根据脏污次数和洗涤次数来综合判断洗衣机是否满足杀菌条件的方法显然比仅仅根据洗涤次数来判断是否满足杀菌条件的方法更加准确。
需要说明的是，与第一种用于洗衣机的杀菌控制方法类似地，在实际应用中，可以通过采集洗涤水的浊度来确定待洗涤物的脏污程度，例如，待洗涤物是衣物，可以在洗衣机的洗涤桶内安装浊度传感器，浊度传感器能够与洗衣机的控制器进行通信，在洗涤衣物时，可以通过浊度传感器采集洗涤水的浊度信息，并将采集到的浊度信息传输给控制器，控制器洗涤水的浊度信息来判断衣物的脏污程度，或者，还可以通过采集待洗涤物的图像信息来确定待洗涤物的脏污程度，例如，待洗涤物是鞋子，洗涤设备是洗鞋机，当然，有的洗衣机也具 备洗鞋功能，可以在洗鞋机的箱体内设置图像采集装置(例如摄像头等)，图像采集装置能够与洗鞋机的控制器进行通信，在洗涤鞋子时，可以通过图像采集装置采集鞋子的图像信息，并将采集到的图像信息传输给控制器，控制器通过对鞋子的图像信息进行分析来判断鞋子的脏污程度，等等，这种对获取待洗涤物的脏污程度的具体确定方法的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
此外，还需要说明的是，可以在洗衣机的控制器内预设一个浊度值与脏污值对照表，采集到洗涤水的浊度后通过浊度值与脏污值对照表来确定待洗涤物的脏污程度。
此外，还需要说明的是，在采集到洗涤水的浊度后，可以不将浊度值换算成脏污值，可以直接将采集到的洗涤水的浊度直接与预设浊度值进行比较，即，用洗涤水的浊度代替待洗涤物的脏污程度，用预设浊度值代替预设脏污值，如果洗涤水的浊度大于预设浊度值，说明待洗涤物的脏污程度大于预设脏污值，使脏污次数加1，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
此外，还需要说明的是，步骤S4与步骤S1、S2、S3可以同步执行，也可以按照任意顺序先后执行，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
下面以根据洗涤水的浊度来确定待洗涤物的脏污程度为例，并结合一个具体的实施例来详细地介绍本发明的第二种用于洗衣机的杀菌控制方法。
如图2所示，本实施例的杀菌控制方法包括以下步骤：
S100：获取洗涤水的浊度；
S200：根据洗涤水的浊度确定待洗涤物的脏污程度；
S300：判断待洗涤物的脏污程度是否大于预设脏污值；
S400：如果待洗涤物的脏污程度大于预设脏污值，则使脏污次数加1；
S500：获取洗涤次数；
S600：判断脏污次数是否达到第一预设值或者第三预设值；
S700：判断洗涤次数是否达到第二预设值或者第四预设值；
S800：如果脏污次数达到第一预设值且洗涤次数达到第二预设值，或者，脏污次数达到第三预设值，或者，洗涤次数达到第四预设值，则使洗衣机执行杀菌操作；
其中，从小到大依次是第一预设值、第三预设值、第二预设值和第四预设值。
以待洗涤物是衣物，第一预设值是10次、第三预设值是15次、第二预设值是20次，第四预设值是25次为例。
在洗衣机对衣物进行洗涤时，通过浊度传感器采集洗涤水的浊度，然后根据洗涤水的浊度确定衣物的脏污程度，将衣物的脏污程度与预设脏污值进行比较，当衣物的脏污程度大于预设脏污值时，说明衣物比较脏，对洗衣机内的脏污情况影响较大，因此，使脏污次数X加1，反之，当衣物的脏污程度小于或者等于预设脏污值时，说明衣物比较干净，对洗衣机内的脏污情况影响较小，因此，使脏污次数X保持不变；获取洗涤次数Y；分别将脏污次数X与第一预设值(10次)和第三预设值(15次)进行比较，分别将洗涤次数Y与第二预设值(20次)和第四预设值(25次)进行比较，判断脏污次数X和洗涤次数Y是否满足以下条件：
条件一：X≥10且Y≥20；
条件二：X≥15；
条件三：Y≥25；
当满足上述三个条件中的任意一个条件时，说明洗衣机满足杀菌条件，此时，使洗衣机执行杀菌操作；当上述三个条件一个也不满足时，说明洗衣机不满足杀菌条件，则不使洗衣机执行杀菌操作。
需要说明的是，与第一种用于洗衣机的杀菌控制方法类似地，“使洗衣机执行杀菌操作”可以是使洗衣机自动启动杀菌模式以对洗衣机进行杀菌，示例性地，洗衣机包括杀菌装置，当满足杀菌条件时，洗衣机可以自动使杀菌装置运行，以对洗衣机进行杀菌；或者，“使洗衣机执行杀菌操作”也可以是使洗衣机发出提示，以告知用户洗衣机需要进行杀菌，示例性地，洗衣机包括语音播放器，当满足杀菌条件时，使语音播放器播放语音，以告知用户需要对洗衣机进行杀 菌了，或者也可以使洗衣机的控制面板显示文字，再或者使洗衣机上的指示灯显示报警颜色等等，如果洗衣机有杀菌装置，用户可以直接启动杀菌装置对洗衣机进行杀菌，如果洗衣机没有杀菌装置，用户需要手动添加杀菌剂等对洗衣机进行杀菌。
此外，还需要说明的是，步骤S500与步骤S100、S200、S300、S400可以同步执行，也可以按照任意顺序先后执行，同样地，步骤S600和步骤S700可以同步执行，也可以按照任意顺序先后执行，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
此外，还需要说明的是，上述介绍的具体实施方式是本实施例中最优选的实施方式，当然还有一些次优选的实施方式，这些次优选的实施方式也在本发明的保护范围之内，例如：
第一次优选实施方式：只设置判断条件一，在这种情形下，步骤S600改成判断脏污次数是否达到第一预设值，步骤S700改成判断洗涤次数是否达到第二预设值；当脏污次数达到第一预设值且洗涤次数达到第二预设值时，使杀菌装置运行；
第二次优选实施方式：只设置判断条件一和条件二，在这种情形下，步骤S600不变，步骤S700改成判断洗涤次数是否达到第二预设值；当满足这两个条件中的任意一个条件时，说明洗衣机满足杀菌条件，也就是说，当脏污次数达到第一预设值且洗涤次数达到第二预设值时，或者，当脏污次数达到第三预设值时，使杀菌装置运行；
第三次优选实施方式：只设置判断条件一和条件三，步骤S600改成判断脏污次数是否达到第一预设值，步骤S700不变；当满足这两个条件中的任意一个条件时，说明洗衣机满足杀菌条件，也就是说，当脏污次数达到第一预设值且洗涤次数达到第二预设值时，或者，当洗涤次数达到第四预设值时，使杀菌装置运行。
这些次优选的实施方式虽然没有达到最优的技术效果，但与现有技术相比，也能够提高判断的准确性。
优选地，第一预设值包括第一主预设值和第一辅预设值，第一主预设值大于第一辅预设值，第二预设值包括第二主预设值和第二辅预设值，第二主预设值大于第二辅预设值，本实施例的杀菌控制 方法还包括：获取环境温度；将环境温度与预设温度进行比较；当环境温度低于预设温度时，采用第一主预设值和第二主预设值为判断基础；当环境温度高于或者等于预设温度时，采用第一辅预设值和第二辅预设值为判断基础。
即，第一预设值包括两个大小不同的主预设值和辅预设值，第二预设值也包括两个大小不同的主预设值和辅预设值，根据环境温度来选择主预设值和辅预设值中一个作为判断基础。
示例性地，预设温度为25度，第一主预设值为10次，第一辅预设值为8次，第二主预设值为15次，第二辅预设值为12次，当环境温度低于25度时，说明环境温度比较低，洗衣机内不易滋生细菌，在这种情形下，采用第一主预设值(10次)和第二主预设值(15次)为判断基础，当脏污次数达到10次且洗涤次数达到15次时，洗衣机满足杀菌条件；当环形温度高于或者等于25度时，说明环境温度比较高，洗衣机内易滋生细菌，在这种情形下，采用第一辅预设值(8次)和第二辅预设值(12次)为判断基础，即，当脏污次数达到8次且洗涤次数达到12次时，就使洗衣机进行杀菌，以提高洗衣机的杀菌频率。
优选地，本发明的洗衣机包括杀菌装置，“使洗衣机执行杀菌操作”的步骤具体包括：使杀菌装置运行。当洗衣机满足杀菌条件时，洗衣机可以自动使杀菌装置运行以对洗衣机进行杀菌。其中，杀菌装置是电解水杀菌装置，通过电解水杀菌装置能够有效地将洗衣机内的污垢清除，以对洗衣机进行杀菌。当然，也可以将杀菌装置设置为其他类型的杀菌装置，例如杀菌剂或者杀菌液投放装置、紫外线杀菌装置、臭氧杀菌装置等，这种对杀菌装置的具体类型的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
需要说明的是，当杀菌装置运行后，脏污次数和洗涤次数全部清零重新开始计数。
优选地，“使杀菌装置运行”的步骤具体包括：在洗衣机完成洗涤作业之后，再使杀菌装置运行。也就是说，当洗衣机满足杀菌条件时，先暂时不使杀菌装置启动，等到洗衣机执行完洗涤作业之后再使杀菌装置运行。需要指出的是，当用户将衣物从洗衣机内取出后才 表示洗衣机执行完洗涤作业，通过这样的设置，既能够保证洗涤程序顺利地进行，也能够避免对洗涤的衣物造成损害。可以通过图像采集装置采集洗涤桶内的图像信息来判断洗涤桶内的衣物是否被取出，或者，也可以通过在洗涤桶上设置重量传感器采集重量信息来判断洗涤桶内的衣物是否被取出，等等。
优选地，“获取洗涤水的浊度”的步骤具体包括：以分段方式获取洗涤水的多个浊度值；计算多个浊度值的平均值；将平均值作为洗涤水的浊度。通过获取洗涤水的多个浊度值，以多个浊度值的平均值作为洗涤水的浊度，能够提高判断的准确性。示例性地，在洗衣机洗涤衣物时，每隔5秒钟获取一次洗涤水的浊度值，检测时间为10分钟，即共获取120个浊度值，将这120个浊度值的平均值作为洗涤水的浊度。当然，获取的浊度值的数量不限于上述情形中的120个，还可以是100个或者200个等，这种对获取的浊度值的具体数量的调整并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
