Description

一种定位装置及洗衣机 技术领域
本发明属于洗衣处理设备技术领域，具体涉及一种对洗衣机内筒进行定位装置止的定位装置；尤其涉及一种具有在执行洗涤程序时脱水孔封闭的无孔内筒的、装有对无孔内筒进行锁止的定位装置的洗衣机。
背景技术
洗衣机大体上可分为波轮式、搅拌式及滚筒式洗衣机。一般来说，洗衣机是通过水和洗涤剂的作用去除洗涤物的污渍。
波轮式洗衣机通过将洗涤槽的中央的波轮左右旋转，从而进行洗涤操作。搅拌式洗衣机通过将洗涤槽中央的旋转翼片左右方向旋转，从而利用水流和洗涤物之间的摩擦力进行洗涤操作。滚筒式洗衣机通过旋转内筒，对衣物进行摔打，从而进行洗涤操作。
在滚筒式洗衣机中，一般具有壳体，内部安装有用于容纳洗涤水的外筒，在外筒的内侧设置有用于容纳洗涤物的内筒，在外筒的背面设置有用于旋转上述内筒的电机和轴。
此外，还有对洗衣进程控制的控制部，一般是控制面板，以及进水和排水机构等等。滚筒式洗衣机利用水槽中储存的洗涤水和内筒中的洗涤物的摩擦力，以及洗涤水中含有的洗涤剂的化学作用去除洗涤物中含有的污渍。
而现在无论波轮式、搅拌式、还是滚筒式洗衣机的内外筒之间普遍留存有大量污垢，为了避免对洗涤水的污染，将内外筒合二为一，使洗涤水仅在内筒中流动、以克服内外筒之间留存污垢的洗衣机就成为了研发热点。
但是在洗衣机执行洗涤过程中，为了便于门体打开取放衣物、向内筒中进排水等功能，普遍需要将内筒进行定位、使其停转至固定位置，以保证后续动作的顺利执行。因此，如何设置一种对洗衣机内筒进行可靠锁止的定位装置，就成了急需解决的技术问题。
有鉴于此，特提出本申请。

如图1至图5所示，本发明实施例中介绍了一种洗衣机，所述洗衣机包括安装于壳体1内的内筒，内筒的至少一端密封设置，内筒的密封端中心连接有同轴设置、向外凸出的转轴7，转轴7的另一端与电机转子3相连接，以使内筒在转轴7的传动作用下随电机转子3共同旋转。
本发明实施例中的洗衣机，可以为现有的任一一种具备内筒的洗衣机，内筒外部可以设置外筒2、也可以不设外筒2，内筒可以为具有脱水孔的正常内筒结构、也可以为在洗衣机执行洗涤程序时形成盛水容器的无孔内筒。
本发明实施例中，洗衣机上设置有对转子3锁止、使内筒停转至固定位置的定位装置4，以达到洗衣机内筒停转至固定位置，实现对洗衣机的内筒进行锁止定位、并保持至固定位置静止不动的使用目的。
本发明实施例中，定位装置4相对内筒固定设置，定位装置4包括一可伸缩移动的锁舌43，电机转子3上设有锁止槽42，伸出的锁舌43可相应插入锁止槽42中、以对转子3进行制动定位。本发明实施例中，定位装置4可以安装于内筒外部套装的外筒2上、也可以直接安装于壳体1上、还可以安装于与壳体1相连的独立支撑件上，但均需保证锁舌43不随内筒共同旋转。
如图1至图5所示，本发明实施例中，以内筒外部设置外筒2、内筒为在洗衣机执行洗涤程序时形成盛水容器的无孔内筒的洗衣机为例进行展开论述：
本发明实施例中，电机装于外筒2上、并处于外筒底背向内筒一侧，且电机转子3同轴安装于外筒底、并与穿过外筒底的转轴7相连接设置。定位装置包括：电机转子3上设有径向凹陷的锁止槽42，定位装置4安装于外筒2上，定位装置4的锁舌43可沿转子3径向伸缩移动，锁舌43与锁止槽42处于同一转子3的转动截面中，伸出的锁舌43可相应插入锁止槽42中、以对转子3进行制动定位，使转子3停转后内筒保持于固定位置。
如图2至图5所示，本发明实施例中，定位装置4包括与外筒2固定连接的外壳41，安装于外壳41内的锁止电机44，锁止电机44的输出端可产生伸缩位移，锁止电机44的输出端直接、或经传动结构与旋转体8相连，旋转体8上设有共同转动、以拨动锁舌43产生伸缩位移的驱动部40。
本发明实施例中，旋转体8的轴线与锁舌43的伸缩方向相垂直，旋转体8的一侧设有沿轴线平行方向凸出的驱动部40，锁舌43上设有径向凸出的、与至少部分驱动部40共面设置的干涉部433，用于旋转体8转动过程中驱动部40与干涉部433相接触、推动锁舌43伸缩移动。
本发明实施例中，为了保证锁舌43伸缩移动的顺畅进行如下设置：锁舌43为一沿转子3径向延伸的杆状结构，外壳41上设有与杆状锁舌43相对应重合设置的开口，杆状锁舌43靠近电机转子3的一端为插入锁止槽42的插接端431、相对另一端与锁止电机44的输出端与旋转体8上所设驱动部40相限位接触、或分离，以受驱动部40作用而产生沿轴向的伸缩移动。同时，本发明实施例中，为了提升锁舌43拉出锁止槽42、复位动作的可靠度，进行如下设置：在外壳41与锁舌43之间设置弹性装置，例如：弹簧45、压力杆等；利用弹性装置的弹力变形而对锁舌43提供推入锁止槽42的弹性推力。本发明实施例中，以弹性装置由弹簧45构成为例进行说明：锁舌43远离插接端431的另一端与外壳41之间连接有弹簧45；弹簧45沿锁舌43伸缩方向延伸，以利用弹簧45自身弹性而对锁舌43提供推入锁止槽42的驱动力。
本发明实施例中，干涉部433的凸出端处于旋转体8轴线一侧，干涉部433的凸出端与旋转体8轴线之间距离小于驱动部40与旋转体8轴线之间距离。
本发明实施例中，干涉部433的凸出端为沿锁舌43伸出方向、逐渐远离旋转体8中心的斜面，旋转体8的转动方向为自斜面远离旋转体8侧向靠近旋转体8侧旋转；或者，干涉部433的凸出端呈与旋转体8的旋转路径相配合的圆弧面，圆弧面同样设置为沿锁舌43伸出方向、逐渐远离旋转体8中心，且旋转体8的转动方向依然为自圆弧面远离旋转体8侧向靠近 旋转体8侧旋转。
本发明实施例中，旋转体8为旋转齿轮47，旋转齿轮47的轴线与锁舌43的伸缩方向相垂直；驱动部40为旋转齿轮47一侧凸出的凸起，凸起与旋转齿轮47不同轴设置、且二者轴线相平行设置；锁止电机44的输出端与旋转齿轮47的轴线、锁舌43的伸缩方向均相垂直，旋转齿轮47直接或经减速齿轮48与螺杆、或蜗杆47相啮合，锁止电机44的输出端与螺杆、或蜗杆47相连，以利用蜗轮蜗杆、或螺杆结构将锁止电机44的旋转作用力传递至旋转齿轮47、用于驱动旋转齿轮47转动。
本发明实施例中，如图3所示，旋转齿轮47转动至驱动部40与锁舌43的干涉部433刚刚相脱离，锁舌43失去驱动部40的支撑作用，弹簧49对锁舌43施加向外的推力，使锁舌43的插接端431与转子3外周相接触，而随着转子3的旋转而使插接端431对应插入转子3的锁止槽42中(如图2所示)；而在定位装置4解锁过程中，旋转齿轮47转动至驱动部40与锁舌43的干涉部433相接触，随着旋转齿轮47的转动使锁舌43受驱动部40的支撑作用、克服弹簧49的弹力而向远离转子3中心方向移动，使锁舌43的插接端431与转子3上的锁止槽42相脱离(如图4所示)。
优选的，为了保证锁紧可靠性，锁舌43需由不可产生弹性变形的材质构成，例如：金属等。
本发明实施例中，锁止槽42的敞口设置于转子3的外周侧，锁舌43对应安装于外筒2上、并可产生沿转子3径向向中心方向凸出的伸缩移动；或者，锁止槽42的敞口设置于转子3的内周侧，锁舌43对应安装于外筒2上、并可产生沿转子3径向向外周方向凸出的伸缩移动。优选的，为了避免锁舌43与电机内部的其他组件，例如：定子等产生干涉，将锁止槽42朝向转子3的外周敞口设置、并将定位装置4装于转子3外周的外筒2上，利用锁舌42产生沿转子径向向中心方向凸出的伸缩移动对转子3进行制动锁止。当然，为了便于加工，还可以将锁止槽42设置为贯穿转子3的镂空部，依然可实现对锁舌42对应插接固定的目的。
如图1所示，本发明实施例中，电机转子3包括一圆盘状的板材结构，圆盘状的板材结构外周向外筒底一侧弯折形成筒形折边，锁止槽42设于转子3的筒形折边上。
本发明实施例中，洗衣机上设有对内筒、和/或转子3转动过程中的相对位置进行检测的位置检测装置9；所述的位置检测装置9可以采用现有技术中的任一形式的、对转动物体进行相对位置检测的结构。例如：所述的位置检测装置包括设于转子3外周任一位置处的永磁铁，设于外筒2上、对永磁铁进行检测的霍尔传感器。通过对永磁铁与锁止槽在转子上设置 位置、及霍尔传感器和定位装置4在外筒上设置位置进行合理调整，使永磁铁与锁止槽42之间的偏移角度和霍尔传感器与定位装置4之间的偏移角度等大设置，以在永磁铁转动至霍尔传感器可检测到的相对位置时，控制锁止电机44工作、推动锁舌43伸出、对应插入电机转子3上的锁止槽42内、实现内筒转至固定位置并锁止的效果。
如图1至5所示，本发明实施例中，洗衣机上设有对定位装置4是否锁止转子3进行判定的检测装置；所述的检测装置可以采用现有技术中的任一形式的、对定位装置4的锁舌相对位置进行判定的检测结构。例如，采用如附图中所示的利用接触碰撞而产生触发信号的微动开关对锁舌43相对位置进行精确检测。所述的检测装置包括设于随锁舌43共同移动的触碰部432，设于外筒2上的、与触碰部432对应相接触的微动开关，以在锁舌43处于对应插入锁止槽42的位置时触碰部432与微动开关相接触而发出电机转子3锁止信号。
本发明实施例中，锁舌43上设有径向凸出的触碰部432，定位装置4的外壳41中设有沿锁舌43伸缩方向间隔排布的第一微动开关5和第二微动开关6，触碰部432处于第一微动开关5和第二微动开关6之间。第一微动开关5和第二微动开关6相沿与锁舌伸缩方向向垂直的方向延伸，且第一微动开关5和第二微动开关6的至少部分与触碰部432处于同一竖直面中；第一微动开关5和第二微动开关6之间的间隔距离等于锁舌42伸缩移动距离，以使得在锁舌43对应插入锁止槽42位置时、触碰部432与第一微动开关5相接触、发出电机转子3锁止信号；在锁舌43复位至与锁止槽42相脱离位置时、触碰部432与第二微动开关6相接触、发出电机转子3解锁信号。从而，使得洗衣机接收到锁止信号后控制洗衣机电机停止工作、接收到解锁信号后控制洗衣机电机开始工作、驱动内筒转动，避免电机开闭工作节点不同步、造成锁舌43和/或电机转子3损坏情况的发生。(未在附图中注明)
本发明实施例中，为了避免检测与驱动之间的相互干涉，将触碰部432与干涉部433设于杆状锁舌43的相对两侧，以提升装置的运行稳定性；同时，为了进一步减小定位装置4的体积，将锁止电机44与锁舌43在锁舌43伸缩方向上交错排布，以提升空间利用率、减小定位装置的整体尺寸。
本发明实施例中，锁舌43对应插入锁止槽42的插接端431具有外径逐渐收窄的外周面，以使锁舌43可利用收窄的外周面引导插入锁止槽42内。优选的，锁舌插接端431的外周面具有至少一处径向增大的凸出部，以利用凸出部与锁止槽42内壁相限位接触，实现对锁舌43相对位置的固定，进而提升插接牢靠度。
本发明实施例中的定位装置4设置于内筒为在洗衣机执行洗涤程序时形成盛水容器的无 孔内筒的洗衣机上，以在内筒制动减速过程中利用定位装置4对内筒进行辅助减速，尤其是可实现内筒保持静止时处于固定位置，以保证后续的进水、排水、脱水、开门等动作顺利执行。
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。
