Description

一种洗衣机减振部件 技术领域
本发明涉及减振部件，尤其是一种洗衣机减振部件，属于洗衣机装置领域。
背景技术
传统的洗衣机减振部件只是在洗衣机脱水时对洗衣机起到减振作用，没有其他的拓展功能。洗衣机在使用过程中，为了根据衣物重量确定进水量，同时，为了对洗衣机脱水启动时外桶的振动进行检测控制，需要一种具有可以称重传感功能的减振部件。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗衣机减振部件，能够实现洗衣机外桶的减振。
为解决上述技术问题，本发明采用技术方案的基本构思是：

进一步的，在吊杆下端固定设置有底托，底托承载弹簧及磁体。
进一步的，还包括滑动皮碗，滑动皮碗位于底托与磁体之间，滑动皮碗为环形，套设在吊杆上，且滑动皮碗直径与套管的内径相配合。
进一步的，磁体为具有下底的桶状，其下底具有中心通孔，磁体下底承载弹簧。
进一步的，磁体底部为具有中心通孔的凸台形，磁体通过中心通孔套在吊杆上，磁体的台阶面承载弹簧。
进一步的，弹簧的下端与磁体内底面相抵并受其支撑。
进一步的，弹簧的下端套在磁体中间部分上，且两者紧密配合。
进一步的，底托中心部穿过滑动皮碗和磁体中心部。
进一步的，弹簧为梭形，弹簧两端的内径小，中间部分内径大，避免在压缩时与磁体摩擦。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。

下面结合附图对本发明的具体实施方式作进一步详细的描述。

图3是本发明一种洗衣机减振部件结构示意图。
1、吊杆座 2、吊杆 3、套管 4、弹簧 5、磁体 6、电磁线圈 7、导线 8、滑动皮碗 9、底托。
具体实施方式
实施例一
一种洗衣机减振部件，包括吊杆、弹簧、套管及电磁传感装置，电磁传感装置包括电磁线圈、磁体，吊杆上端与洗衣机机壳连接，在本实施例中为了使吊杆与洗衣机机壳更好地连接，吊杆上端设置有吊杆座，吊杆座与洗衣机的机壳内壁的卡环连接，卡环托载吊杆座，从而使吊杆与洗衣机机壳连接。吊杆下部套装套管，吊杆套装套管的一端与外桶上的悬挂座连接，套管位于悬挂座下方托载悬挂座，利用四个本发明所述的洗衣机 减振部件将洗衣机外桶悬吊在机壳内。
磁体设置在套管内，并相对固定在吊杆上，套管可滑动地套设在吊杆上，电磁线圈固定套设在套管外侧。弹簧位于磁体与套管之间，利用弹簧的弹力，弹簧下端将磁体压制，使其与吊杆相对静止，套管是可滑动地套设在吊杆上。套管受力在吊杆上滑动时，电磁线圈的电感量发生变化，洗衣机的电脑程控器控制程序测定电感量的变化，来确定衣物重量。
在本实施例中，磁体与吊杆固定设置，如图3所示，电磁线圈固定套设在套管外侧，在其他实施例中，可以为电磁线圈与吊杆固定设定，磁体与套管固定设置。
套管可滑动地套在吊杆上，弹簧为压缩弹簧，弹簧套在吊杆上且位于套管内腔，吊杆下端与弹簧下端接触并承载弹簧，弹簧上端与套管内腔壁顶部接触使弹簧上端始终位于套管内腔。
如图1所示，在本实施例中，磁体位于套管中，弹簧设置在磁体与套管之间。
为了更好地承载弹簧及磁体，在吊杆下端固定设置有底托，底托承载弹簧及磁体。
在吊杆下端设置有滑动皮碗，在本实施例中，滑动皮碗位于底托上部、弹簧及磁体下部，滑动皮碗为环形，套设在吊杆上，且滑动皮碗外径与套管的内径相配合。在吊杆与套管相对滑动时，滑动皮碗随吊杆一起动作，起到一定的阻尼作用，可防止吊杆偏移导致吊杆下端及底托、磁体与套管发生碰撞。
如图1所示，磁体为具有下底的桶状，其下底具有中心通孔，磁体套在吊杆上，弹簧套在吊杆上且弹簧的下端位于磁体的桶状内腔中，磁体下底承载弹簧，磁体下底的上表面中心具有环形凸台，弹簧下端位于环形凸台外周。滑动皮碗夹在磁体与底托之间。
电磁线圈通过导线与信号接收器连接，信号接收器与电脑程控器连接。
洗衣机开始工作前，利用减震部件先进行预称重，用户投入衣物以后再进行称重。通过两次称重确定衣物重量，进而根据衣物的重量判断需要进水的量。在洗衣机内桶进水时，洗衣机内桶中进水而使内桶重量增加时，外桶向下压套管，套管受弹簧作用沿吊杆缓慢向下滑动，吊杆上的磁体与套管上的电磁线圈产生相对运动，电磁线圈的电感量发生变化，电磁线圈的电感量变化输出到信号接收器进行滤波整流及信号放大再输出到电脑程控器，电脑程控器根据同一时间内的波形数量来判断磁体的位移量，从而检测并控制进水量。
在洗衣机脱水启动时，外桶会发生振动，通过弹簧的形变来吸收振动能量从而实现减振，并且通过对电磁线圈进行电感量的变化检测进而得知洗衣机外桶振动大小，通过 洗衣机的电脑程控器控制程序进行负载纠偏，提高洗衣机的脱水运行稳定性，满足用户的使用需求，提升使用体验。
可以理解的是，电磁线圈和磁体的相对运动关系与电磁线圈电感量的变化之间的关系已通过实验得知，而电磁线圈和磁体的相对运动关系与套管所受外力之间的关系也已通过实验得知。
本发明一种洗衣机减振部件，吊杆设置吊杆座的一端与洗衣机的机壳连接，套装套管的一端与洗衣机外桶连接，将洗衣机外桶悬吊在机壳内。洗衣机开始工作前，洗衣机减振部件先进行预称重，用户投入衣物以后再进行称重。由于洗衣机内桶和外桶连在一起，外桶施力于套管上，套管相对吊杆滑动进而使电磁线圈与磁体相对运动，从而使电磁线圈中的磁通量发生变化，电磁线圈内的电感量发生变化，电脑程控器根据电感量变化判断衣物重量并确定进水的量。在洗衣机内桶进水时，由于内桶和外桶连在一起，外桶对套管的压力变大进而压缩弹簧，套管相对吊杆滑动，进而使分别固定在吊杆与套管上的磁体和电磁线圈发生相对位移，使得通过电磁线圈的磁通量发生变化，电磁线圈内的电感量发生变化，电脑程控器根据电感量变化判断并控制进水量。在洗衣机脱水启动时，外桶会发生振动，通过弹簧的形变来吸收振动能量从而实现减振，并且通过对电磁线圈中进行电感量的变化检测进而得知洗衣机外桶振动大小，通过洗衣机的电脑程控器控制程序进行负载纠偏，调整电机转速，提高洗衣机的脱水运行稳定性。
实施例二
如图2所示，本实施例与实施例一的不同在于：磁体位于弹簧形成的柱状空间内并与吊杆相对固定设置。
磁体底部为具有中心通孔的凸台形，磁体的台阶面承载弹簧，滑动皮碗夹在磁体与底托之间。
磁体沿其轴向分为外径不同的三部分，三部分从上到下外径依次增大。磁体最上面部分的外径最小，最下面部分的外径最大。
弹簧的下端与磁体内底面相抵并受其支撑。弹簧的下端套在磁体中间部分，且两者紧密配合。弹簧下端压制磁体使得磁体与吊杆相对静止。
由于磁体分为三个部分，且弹簧的下端套在磁体中间部分即磁体的第二部分，且两者紧密配合，这样弹簧下端卡在磁体的第二部分外围，使得弹簧不会径向晃动。而磁体最上面的部分由于其外径小于磁体中间部分的外径，因此，磁体最上面部分与弹簧之间具有空隙，在弹簧压缩伸展时，磁体最上面部分与弹簧不会发生摩擦，从而避免了磁体受到磨损。
弹簧为梭形，弹簧两端的内径小，中间部分内径大。弹簧的此种结构设计使得其能更好地避免与磁体的摩擦。
底托中心部穿过滑动皮碗支承在磁体中心底部。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
