实施例九
本实施例主要解决无孔内筒洗衣机的内筒门实际未锁定，内筒门却仍闭合在内筒口或者打开的角度特别小，致使位置检测装置误判内筒门已锁定到位的问题，具体方案如下:
如图22和图23所示，本实施例提供的滚筒洗衣机，包括：内筒17，具有内筒口；
内筒门6，所述内筒门6可开启/闭合地安装在内筒口，所述内筒门6可通过连接件连接在内筒口上，或者扣合在内筒口上，在启动洗衣机前需要通过锁定机构将内筒门6锁定好，以防止内筒17高速旋转造成安全事故发生；位置检测装置，检测内筒门6是否锁定到位，避免由于用户疏忽内筒门6未锁定或者人为主观判断出现错误；关门阻碍装置55，对内筒门6施加阻碍关闭的力，通过设置的关门阻碍装置55，在内筒门6未锁定时，阻碍内筒门6关闭，将内筒门6打开一定的角度A，使得内筒门6上的被检测端子38不在位置传感器33的感应区54内，使得位置检测装置能够更准确地判断内筒门6是否锁定。避免了现有技术中内筒门6未锁定，而内筒门6却仍闭合在内筒口上或者打开的角度特别小，致使位置检测装置误判内筒门6已锁定好，在洗衣机启动后，内筒17高速旋转造成破坏或者安全事故发生。
本实施例中，所述关门阻碍装置55可以设置在内筒门6上；或者，也可以设置在内筒17上；或者，设置在内筒门6和内筒17之间。本实施例中，所述关门阻碍装置55为设置在内筒门6上或者内筒17上或者内筒17和内筒门6之间的弹性件，所述弹性件具有一定的弹性，所述弹性件的两弹性端止抵在内筒的内壁和内筒门的内壁之间，所述弹性件的一端连接在内筒17或者内筒门6上，另一端抵接在内筒17和内筒门6上，或者两端均抵接在内筒17和内筒门6上，所述弹性件在关闭内筒门6时产生一定的阻力，若内筒门6没有锁定，会将内筒门6弹开一定的角度。

更优选地，所述扭簧的前直线段部的外延端弯曲设置而形成用于连接内筒门6的第一连接部，所述扭簧的后直线段部的外延端弯曲设置而形成用于连接内筒17的第二连接部，所述第一连接部和第二连接部为弯钩结构，钩挂连接在内筒门6和内筒17上，或者为螺旋形结构，套设连接在内筒门6和内筒17上对应设置的连接结构上，将扭簧的两个脚部延伸形成的前直线段部和后直线段部分别钩挂或穿套连接在内筒门6和内筒17上，使该扭簧的两个脚部能够与内筒门6和内筒17稳定连接，在使用过程中不会存在扭簧脚部与内筒门6和内筒17因连接不稳定而脱开的问题。
本实施例中，所述关门阻碍装置55可以为一端连接在内筒17内壁另一端抵接在内筒门6内壁的液压伸缩杆/气压伸缩杆/压缩弹簧，或者为一端连接在内筒门6内壁另一端抵接在内筒17内壁的液压伸缩杆/气压伸缩杆/压缩弹簧，或者为连接在内筒门6和内筒17之间的液压伸缩杆/气压伸缩杆/压缩弹簧，所述关门阻碍装置55也可以为其他可伸缩、折叠并且能够对内筒门6关闭产生一定阻力的机构。
本实施例中所述位置检测装置，包括被检测端子38，所述被检测端子38设置在内筒门6上；位置传感器33，所述位置传感器33对应被检测端子38设置，具有能够感应到被检测端子38的感应区54。本实施例所述的滚筒洗衣机还包括：套设在内筒17外部与内筒17同轴的外筒18，所述位置传感器33对应设置在外筒18上，与被检测端子38的位置相对应。或者还包括：设置在内筒17外的壳体19，所述位置传感器33对应设置在壳体19上，与被检测端子38的位置相对应。

较为优选地，所述位置检测装置干簧管式传感器，所述位置传感器33为干簧管传感器，所述被检测端子38为永磁体，所述被检测端子38设置在内筒门6上靠近锁定件52的位置，所述位置传感器33设置在外筒18内壁靠近内筒17筒口的位置。
当内筒门6上的锁舌锁入在内筒的锁槽内时，内筒门6被锁定，进而扭簧无法实现将内筒门6打开一定角度，位于内筒门6上的永磁体位于干簧管传感器的感应区54内，所述干簧管传感器形成通路，所述洗衣机的控制单元判定内筒门6已锁定；当锁舌没有锁定在锁槽内时，内筒门6未锁定，所述扭簧产生的力强制将内筒门6打开如图23中所示的夹角A，使得永磁体位于干簧管传感器的感应区54外，此时干簧管传感器为断路，所述洗衣机的控制单元判定内筒门未锁定，进而报警，提醒用户锁定内筒门。
实施例十
本实施例与上述实施例九解决的技术问题相同，是在实施例九的方案的基础上进一步优化的技术方案，具体方案如下:
如图24-26所示，本实施例提供的滚筒洗衣机，包括：内筒17，具有内筒口；内筒门6，可开启/闭合地安装在内筒口；位置检测装置，检测内筒门6是否锁定到位；磁性元件，吸合/排斥内筒门6，对内筒门6施加阻碍关闭的力。本实施例中采用非接触式的磁性元件来阻碍内筒门的关闭，相比于上述实施例九中的关门阻碍装置，不仅减少了其与内筒门和内筒之间的摩擦损耗，损坏率低，而且结构简单、灵敏度更高，可控性强。
本实施例所述的磁性元件可以单独设置，也可以与实施例九中的关门阻碍装置一同设置在洗衣机上，起到双重保险的作用，进一步降低位置检测装置误判的概率，以防止单独设置时关门阻碍装置或者磁性元件二者当中的某个出现故障，不能起到阻碍门体关闭的作用。
在一种实施方式中，如图24所示，所述磁性元件包括设置在内筒门6内壁上的第一磁性元件61和对应第一磁性元件61设置在内筒17筒口位置的第二磁性元件62，所述第一磁性元件61和第二磁性元件62相互排斥，在关闭内筒门6时产生阻碍内筒门6的关闭的力，若内筒门6没有被锁定，第一磁性元件61和第二磁性元件62产生的排斥力会使得内筒门6保持打开一定的角度。
所述第一磁性元件61和第二磁性元件62的同性磁极相对，更优选地，所述第一磁性元件61和第二磁性元件62为两个永磁体，采用永磁体其磁性不会减弱或者消失，避免了频繁充磁带来的麻烦，所述内筒门6和内筒17上设置有用于安装第一磁性元件61和第二磁性元件62的安装位，可通过卡 接或者粘接等方式固定，结构简单，安装方便。
在另一种实施方式中，还包括设置在内筒17外的壳体19，所述磁性元件包括设置在内筒门6的外壁的第一磁性元件61和对应第一磁性元件61设置在壳体19内壁上的第二磁性元件62，所述第一磁性元件61和第二磁性元件62相互吸合，在关闭内筒门6时设置在壳体19上的第二磁性元件62对位于内筒门6上的第一磁性元件61产生磁性吸引力进而吸合内筒门6，阻碍内筒门6的关闭，若内筒门6没有被锁定，产生的吸引力会使得内筒门6保持打开一定的角度。
或者，所述壳体19上对应内筒门6的位置设置有一机门5，所述机门5通过机门轴57连接在壳体19上，所述磁性元件包括设置在内筒门6的外壁的第一磁性元件61和对应第一磁性元件61设置在机门5内壁上的第二磁性元件62，所述第一磁性元件61和第二磁性元件62相互吸合，在关闭内筒门6时设置在机门5上的第二磁性元件62对位于内筒门6上的第一磁性元件61产生磁性吸引力，进而吸合内筒门6，阻碍内筒门6的关闭，若内筒门6没有被锁定，产生的吸引力会使得内筒门6保持打开一定的角度。
在上述实施方式中，有以下两种具体的方案：
第一种方案，如图25所示，所述第一磁性元件61为设置在内筒门6上的感磁件或者永磁体，所述感磁件可以为铁、镍、钴等其他金属磁性材料，所述第二磁性元件62为对应第一磁性元件61设置在壳体19或者机门5上的电磁模块，所述电磁模块为一通电线圈或者电磁铁。采用的电磁模块其磁性有无可以通过电流的通断来控制，磁性的强弱可通过电流的大小或者线圈的匝数多少来控制，可控性更高，其对内筒门的吸引的磁性强弱也可以通过控制电流的大小来调控，避免了磁性过弱不能起到吸合内筒门的作用，或者磁性过强，对内筒门造成一定的损伤或者造成关闭内筒门困难等现象发生。在位置检测装置检测到内筒门已经锁定到位后，洗衣机的控制单元则可控制电磁模块断电，节约资源的同时，避免了内筒门锁定后，磁性元件一直产生阻碍门体关闭的力，影响到内筒门的密封效果。
第二种方案，如图26所示，所述第一磁性元件61和第二磁性元件62的异性磁极相对，优选地，所述第一磁性元件61和第二磁性元件62均为永磁体。作为上述方案的替代方案中，所述第一磁性元件61为感磁件，如铁、镍、钴等其他金属磁性材料，所述第二磁性元件62为永磁体；或者，所述第一磁性元件61为永磁体，所述第二磁性元件62为感磁件。采用永磁体和感磁件、永磁体和永磁体配合的方式产生阻碍内筒门6的关闭的阻力，将内筒门6打开一定的角度，其结构简单，成本低，适用推广性强。
如图24至26所示，本实施例中所述位置检测装置，包括被检测端子38，所述被检测端子38设置在内筒门6上；位置传感器33，所述位置传感器33对应被检测端子38设置，具有能够感应到被检测端子的感应区54，优选地，所述位置传感器33为干簧管式传感器，本实施例所述的位置传感器的具体结构、设置的位置及方式与实施例七至九中相同，在此就不再赘述。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
