密封门6上设置用于与内筒17扣合的关闭结构，被检测端子38设置在关闭结构上。
本实施例中还包括套设在内筒17外部与内筒17同轴设置的外筒18，所述位置传感器33设置在外筒18上，与被检测端子38的位置相对应；可选地：所述位置传感器33设置在外筒18的外壁上且与被检测端子38的位置相对应，位置传感器33固定不动，而被检测端子38在密封门6的开启/关闭过程中，随密封门6转动，两者之间的位置随密封门6的转动发生变化，产生的信号值发生变化，洗衣机依据接收到的信号值判断密封门6是否关闭到位。
本实施例中还包括壳体19，所述的内筒17设置在壳体19内，所述的位置传感器33设置在壳体19上，与被检测端子38的位置相对应。
所述位置检测装置为电磁式位置传感器，包括永磁体转子和电磁传感器，永磁体转子为被检测端子38，电磁传感器为位置传感器33；或者光电式位置传感器，包括遮光板和光电传感器，遮光板为被检测端子38，光电传感器为位置传感器33；或者差动电压式传感器，包括衔铁和差动电压传感器，所述衔铁为被检测端子38，所述差动电压传感器为位置传感器33；或者电涡流式传感器，包括金属板和电涡流传感器，所述金属板为被检测端子38，所述电涡流传感器为位置传感器33；或者电容式传感器，包括动极、定极和电容传感器，所述动极为被检测端子38，所述定极和电容传感器为位置传感器33；或者干簧管式传感器，包括磁铁和干簧管传感器，所述磁铁为被检测端子38，所述干簧管传感器为位置传感器33；或者霍尔式传感器，包括永磁铁和霍尔传感器，所述永磁铁为被检测端子38，所述霍尔传感器为位置传感器33。
本实施例中还包括主控制器4，所述主控制器4与位置传感器33之间电连接。
可选的，所述壳体19内设置有与位置传感器33连接的声音报警器，当位置传感器33检测到密封门6没有关闭到位时，及时报警提示用户出现故障或者关闭密封门6。
实施例十
如图23所示，一种洗衣机的控制方法，洗衣机包括:壳体19；洗涤衣物时盛 放洗涤水的内筒17；可开合的安装在内筒17的筒口上的密封门6，以及设置在壳体19内用于推合密封门6关闭的密封门推合装置46，所述控制方法包括：洗衣机控制密封门推合装置46启动推合密封门6关闭。
本实施例中，洗衣机的壳体19上对应内筒17的筒口处开设开口，开口上安装有可开合的门体5，洗衣机的控制系统判断门体5是否关闭，若判断为是，则控制密封门推合装置46启动，推合密封门6关闭；若判断为否，则控制密封门推合装置46保持关闭。
在一种方案中，可以在洗衣机的控制系统中设定可以控制密封门推合装置46启动的控制程序，用户可以根据需要通过控制程序随时启动密封门推合装置46，可以通过按钮\按键或者其他方式选择启动密封门推合装置46。
本实施例中，洗衣机的门体5上设置有电磁锁，用于检测洗衣机的门体5是否关闭，若检测为是，洗衣机的控制系统则控制密封门推合装置46启动，推合密封门6关闭；若检测为否，则控制密封门推合装置46保持关闭状态，不启动。
本实施例中，洗衣机的外筒18内设置有位置检测装置，用于检测密封门6是否关闭到位，所述位置检测装置包括被检测端子38和位置传感器33，所述洗衣机密封门6上设置有被检测端子38，外筒18的内侧壁设置有位置传感器33，本实施例中，洗衣机还包括主控制器4，所述主控制器4与位置传感器33之间电连接。
洗衣机的主控制器4根据位置检测装置检测的信号判断密封门6关闭是否到位，避免出现未关闭的情况，造成洗涤或者漂洗及脱水情况下漏水，或者防止出现由于用户疏忽，导致密封门6未关闭到位高速旋转造成破坏等问题。
当洗衣机检测到门体5关闭锁定后，所述位置检测装置检测洗衣机的密封门6是否关闭，若检测为是，则控制密封门推合装置46保持关闭状态；若检测为否，洗衣机的控制系统则控制密封门推合装置46启动，推合密封门6关闭。
洗衣机检测到门体5关闭锁定后，当位置检测装置检测到密封门6未关闭时，控制密封门推合装置46动作，推合密封门6关闭，密封门推合装置46每次动作后，位置检测装置检测到密封门6仍未关闭到位，则控制密封门推合装置46再次动作，循环执行N次，当N大于N0(N0为设定值)时，则洗衣机暂停并报警；
可选地，所述的N0＝3。
位置检测装置检测的检测方法可以为，将密封门6关闭到位时被检测端子38与位置传感器33之间产生的信号值输入洗衣机的主控制器4中，作为判断密封门6体关闭是否到位的参考信号值。
当洗衣机的主控制器4接收到的被检测端子38与位置传感器33之间产生的信号值等于参考信号值时，洗衣机的主控制器4判定密封门6关闭到位，控制洗衣机进行洗涤；当洗衣机的主控制器4接收到的被检测端子38与位置传感器33之间产生的信号值与参考信号值存在差异时，洗衣机的主控制器4判定密封门6远离关闭到位的位置，控制洗衣机发出报警信号，提醒用户关好密封门6，避免出现未关闭的情况，造成洗涤或者漂洗及脱水情况下漏水，或者防止出现由于用户疏忽，导致门体未关闭到位高速旋转造成破坏等问题。
采用上述技术方案后，本申请与相关技术相比具有以下优点。
1、本申请公开的洗衣机，通过设置的推合装置，实现自动推合密封门关闭,防止由于用户疏忽，导致密封门未关闭的问题，避免了高速旋转密封门脱落的风险，自动化更高。
2、本申请公开的洗衣机，通过在外筒上设置的位置传感器，来监测密封门是否关闭到位，如果没有关闭到位能够报警，及时提示用户关闭密封门。
