背景技术
洗衣机作为人们日常生活中使用最为广泛的一种家用电器，帮助人们摆脱了洗衣的烦恼，给人们带来了极大的便利。但是现有洗衣机一般都包括内筒和外筒，内筒的筒壁上分布多个脱水孔，而在洗涤过程中，内筒与外筒之间的洗涤水不会被利用，造成该部分洗涤水的浪费，且洗涤过程中产生的脏污会随着水流进入内筒与外筒之间而被积累，随着长时间的使用，脏污的累积会影响洗涤效果，降低用户使用体验。
为了解决上述问题，现在也提出了一些专利，例如申请号为201410215346.3，名称为一种滚筒洗衣机的中国发明专利，该发明涉及一种滚筒洗衣机，包括箱体，箱体内设有内筒和外筒，外筒与箱体之间设有门封，内筒与驱动装置相连，所述的内筒为无孔内筒，且所述的内筒为筒底处直径小、筒口处直径大的锥形筒，内筒的筒口处向内呈弧形收拢，所述的门封上设有进水导管，进水导管的一端与洗涤水快速加热装置相连，进水导管的另一端穿过门封伸入内筒内，所述的外筒上设有排水口及水压检测装置。由上述技术方案可知，该发明的内筒为无孔内筒，通过设置在门封上的进水导管实现内筒进水，并通过内筒自身的形状在脱水过程中实现排水，这样可以避免在内、外筒之间存水，大幅节约了洗涤用水量。

具体实施方式
下面结合附图对本发明的一种洗衣机的控制方法进行详细描述：
实施例一
如图1至图3所示，本实施例的一种洗衣机，包括：
机壳1；
内筒5，设置在机壳1内，具有独立盛放洗涤水的洗涤腔室；
以及水位检测装置，水位检测装置包括检测部件7和感应部件8，所述的检测部件7设置在内筒5上，检测部件7的位置可随着水位的升高/降低而升高/降低，所述的感应部件8对应检测检测部件7的位置变化；所述感应部件8通过检测检测部7件的位置得出内筒5内的水位高度。
本实施例提供一种洗衣机，无需在内筒与外筒之间填充洗涤/漂洗水，不仅避免了内筒与外筒之间污垢附着的可能，避免内筒、外筒脏污，提高了用户健康及用户体验；而且减少了洗衣机的洗涤用水量，节约了耗水量。
本实施例的水位检测装置针对无孔内筒的洗衣机的结构特点，所述的检测部件7设置在内筒5内的位置可随着水位变化而变化，所述的感应部件8设置在内筒5的外部对应检测检测部件7的位置变化，所述感应部件8通过检测检测部7件的位置得出内筒5内的水位高度，实现内筒内的水位检测。
本实施例的检测部件7利用水的物理特性，随着水位变化位置变化，且检测部件7可以不通电，解决了无孔内筒内的结构部件不能供电的问题，感应部件8通过检测检测部件7即可间接检测出内筒内的水位高度，感应部件8设置在内筒的外部，可以设置在固定部件上，可设置在外筒上也可设置在机壳内，这样不影响对感应部件8的供电以及感应部件8与洗衣机的主控制器3之间的数据及控制信号交换。
本实施例的内筒5为筒壁封闭的无孔内筒，内筒的筒口上设置内筒门14，形成独立的密封舱结构15，避免内筒5的衣物出来的可能，及衣物受压及摔打导致由内筒流出或者飞溅出水，避免了内、外筒之间污垢附着的可能，真正实现了内筒与外筒之间无水。
由于滚筒脱水转速会达到1600转/分钟，内筒上的内筒门如果未能锁定好，将会发生安全事故，本实施例的洗衣机具有内筒门锁锁定到位的门锁检测装置，确保内筒门锁定到位，确保锁定判定准确率100％，极大的提高了机器的安全性，提升了用户体验。
作为本实施例的一种实施方式，本实施例所述的检测部件7为设置在内筒5内具有磁性的磁力浮子，所述的感应部件8为磁场感应装置，所述的磁场感应装置通过检测磁力浮子高度变化得出内筒内的水位高度。
本实施例采用磁场感应装置感应磁力浮子的方式解决了无孔内筒洗衣机的水位检测的问题，结构简单，检测精度高。
进一步地，为了解决磁力浮子的安装，本实施例所述的内筒5内设置浮子壳体22，浮子壳体22与内筒5的筒壁之间形成与内筒内部连通的浮子腔室，所述的磁力浮子设置在浮子腔室内且可随着水位变化上下浮动。
具体地，本实施例所述的浮子壳体22安装在内筒5的底壁24上，浮子壳体22与底壁24之间形成沿内筒5的底壁24径向延伸的浮子腔室，所述浮子壳体22靠近内筒5的周侧壁21的一端设置与内筒内部连通的连通口25。
本实施例将浮子壳体22设置在内筒5的底壁24上，不占据内筒5的中部空间，对衣物洗涤过程无影响。浮子壳体22与底壁24之间形成沿内筒5的底壁24径向延伸的浮子腔室，这样可以通过定位内筒5的方式实现浮子腔室沿竖直方向设置进行水位高度 测量。
为了更好的引导磁力浮子上下滑动，提升检测准确性，同时确保磁力浮子在磁场检测装置的检测范围内，本实施例所述浮子壳体内设置用于引导磁力浮子上下浮动的导向结构。
优选地，所述的导向结构为设置在浮子壳体内部的导向杆23，所述的磁力浮子内部具有贯通通道，所述的导向杆23穿过磁力浮子的贯通通道，磁力浮子可沿导向杆上下浮动。
作为本实施例的一种实施方式，本实施例的洗衣机包括主控制器3，所述的磁场感应装置为霍尔传感器，霍尔传感器与主控制器3电连接；所述霍尔传感器的感应电流随着磁力浮子高度变化而变化，主控制器3根据霍尔传感器的感应电流变化得出内筒内的水位高度。
作为本实施例的另一种实施方式，本实施例的洗衣机包括主控制器3，所述的磁场感应装置为干簧管，所述的干簧管包括多个，干簧管设置在内筒外部的路径与磁力浮子在内筒内部上下浮动路径相对应，多个干簧管分别与主控制器3电连接：随着磁力浮子高度变化，与磁力浮子高度位置相对应的干簧管闭合，主控制器3根据各个位置的干簧管闭合信号得出内筒内的水位高度。
优选地，各个所述的干簧管分别对应洗衣机的各个可被设定的水位高度设置，洗衣机进水过程中，当设定水位对应的干簧管闭合，则主控制板判定为进水到设定水位。
进一步地，本实施例的洗衣机，包括外筒4，所述的磁场感应装置设置在外筒4上；优选地，所述的磁场感应装置设置在外筒4的底壁上。
由于内筒在洗衣过程中会转动，但是在检测内筒内的水位时，需要电磁浮子所在的浮子腔室竖直设置，因此，在进行水位检测时需将内筒定位至确定的位置。为了实现这一发明目的，本实施例所述的外筒4上设置定位装置，所述的定位装置具有可伸缩的定位柱，所述的内筒5上具有用于与定位柱配合的定位孔；所述定位装置的定位柱伸出与定位孔相配合将内筒锁定时，所述的磁场感应装置与磁力浮子处于相对位置，且浮子腔室处于竖直位置。
另外，也可通过洗衣机的驱动电机将内筒5锁定在确定的位置。
本实施还给出另一种可实现无孔内筒的水位检测方案，本实施例所述内筒5内设置发光装置，内筒5的筒壁上具有用于发光装置发出光线通过的透光部射出，所述的检测 部件7为设置在内筒5内沿透光部上下浮动的浮子，所述的感应部件为光感应装置：
随着内筒内的水位变化，浮子沿透光部浮动以改变由透光部射出的光线，所述的磁场感应装置通过检测光线变化得出内筒内的水位高度。
上述方式中的发光装置可采用电池供电同时进行密封。
本实施例的洗衣机采用无孔内筒的结构，为了实现无孔内筒的排水，本实施例的内筒侧壁上开设排水孔，排水孔上安装离心排水机构11，离心排水机构11保持排水孔的常闭状态以形成无孔内筒，独立盛放洗涤水，当需要排水时，控制内筒高速转动，离心排水机构11在高速转动的离心作用下降排水孔打开，洗涤水由排水孔排出。优选地，内筒5的筒壁上设置多个提升筋6，所述的离心排水机构11设置在至少一个提升筋6的内部腔室内。
为了提升内筒5的排水效率，本实施例离心排水机构11设置在内筒的周侧壁的中部，内筒的周侧壁由内筒口向离心排水机构11处呈内径逐渐增大的锥形结构10，由内筒的底壁向离心排水机构11处呈内径逐渐增大的锥形结构，从而形成两端小中间大的内筒结构，这样在高速离心排水过程中，可更好的将内筒内的水经锥形结构引导至中间的离心排水机构11出被排出。
本实施例的外筒4的底部连接排水装置13，用于将水引出机壳1。
本实施例的洗衣机具有机壳1，机壳1包括：上台面板17，前面板，后背板和底板。底板上安装固定了底脚9，用于支撑整个洗衣机，前面板安装机门2。机壳1内部具有外筒4，外筒4内同轴设置了内筒5。外筒4用于收集内筒5的排水及内筒5高速离心脱水的排水。内筒5旋转，内筒中设置的提升筋6，不断的提升跌落摔打衣物，以便洗净衣物。内筒5是无孔结构的，外筒4具有中心安装孔，安装固定了轴承。与内筒5紧固连接的内筒轴19穿过所示轴承并连接驱动电机20。
为了实现向本实施例无孔内筒内进水，本实施例的洗衣机的驱动电机20通过内筒轴19与内筒5固定连接带动内筒5转动，所述的内筒轴19内具有连通内筒5内部的中空通道18，洗衣机的进水管路与内筒轴19的中空通道18相连通。进水管路的进水端延伸出洗衣机的机壳1连接水龙头，进水管路依次连通进水阀12、洗涤剂投放装置16及内桶轴19的中空通道18。
本实施例的内筒5上设置用于连通内筒5与外界环境以平衡内筒内部气压的气压平衡机构。
进水时，内筒的密封舱内的气体受压可以通过该均平衡机构溢出，保证气压平衡。
突然断水时，外部大气可以迅速进入内筒的密封舱，并破坏倒吸，保证气压平衡，避免洗涤水被吸入自来水管网。
其他例如脱水时，该气压平衡机构也可以保证内筒气压平衡。
作为本实施例的一种实施方式，所述的气压平衡机构包括开设在内筒轴19上连通内筒5内部与外界环境的均压孔道26，所述内筒5内的最高水位低于内筒轴。这样可以防止内筒5内的水由均压孔道26流出。
本实施例所述均压孔道26包括第一孔道段和第二孔道段，第一孔道段与中空通道相平行设置，其一端连通内筒内部，第二孔道段的一端与第一孔道段相连通，另一端延伸至内筒轴的外周壁上与外筒的内部相通。优选地，所述的第二孔道段与第一孔道段相垂直设置形成L型的均压孔道。
