下面结合附图具体描述根据本发明实施例的滚筒洗衣机100。
如图1和图2所示，根据本发明实施例的滚筒洗衣机100包括箱体20、筒体30、霍尔传感器40和控制器50。
具体而言，箱体20内设有横梁22，筒体30安装在箱体20内，霍尔传感器40设在筒体30和横梁22之间，霍尔传感器40感测筒体30与横梁22的相对位移并将其转化成电信号。控制器50与霍尔传感器40相连，控制器50接收电信号并根据电信号判断筒体30的重量和/或位移。
其中需要说明的是，箱体20上通常设有用于控制滚筒洗衣机100工作的工作台21，控制器50可以设在工作台21上。筒体30可以通过吊装件60和支撑件61安装在箱体20内，吊装件60的两端分别与箱体20的顶板和筒体30的上部相连以吊住筒体30，支撑件61设在筒体30的下部与所述箱体20的底板之间以支撑筒体30
吊装件60和支撑件61可以分别设有两组，即吊装件60设有两个，支撑件61设有两个，两个吊装件60和支撑件61在左右方向上间隔开设置，且分别位于滚筒洗衣机100的左右两侧以保证筒体30在箱体20内的装配稳定性。吊装件60和支撑件61可以分别具有一定的伸缩性，以进一步保证筒体30在箱体20内的装配稳定性。
筒体30内设有滚筒(未示出)，滚筒可滚动地设在筒体30内以进行洗衣和脱水，用户在使用根据本发明实施例的滚筒洗衣机100时，当衣物被放入滚筒中，滚筒和筒体30的整体重量随着衣物的投入而增加，与筒体30相连的吊装件60和支撑件61受力发生形变，吊装件60被向下拉伸，支撑件61被向下压缩，同时，筒体30整体向下发生位移而达到平衡状态。
筒体30发生位移时，筒体30与箱体20的相对位置发生改变，筒体30与横梁22的相对位置也发生改变，两者之间产生相对位移，设在两者之间的霍尔传感器40感测两者的位移变化，并将位移变化的量转化成电信号。该电信号与筒体30上下位移变化以及筒体30中衣物重量成对应关系，电信号包括但是不局限于电压、电流、频率、PWM等，该电信号可以准确反应筒体30的重量，从而可以准确反应滚筒洗衣机100中投入衣物的重量。
控制器50接收经过霍尔传感器40转化后的电信号，通过特定的程序可以实现对电信号的解析，准确判断滚筒洗衣机100中投入衣物的重量以及不平衡感知等功能，控制器50 可以根据当前状态下的称重值，自行调节洗涤程序。
由此，根据本发明实施例的滚筒洗衣机100，通过在筒体30和箱体20的横梁22之间设置霍尔传感器40，筒体30在放置衣物时，由于重力作用会向下运动，与箱体20的横梁22产生相对位移，霍尔传感器40可以感测到该位移，并且将位移转化成电信号传递给控制器50，控制器50接收电信号，并根据电信号精确判断筒体40内衣物的重量，从而自行调节洗涤程序，控制洗涤水量、洗涤时间、洗涤剂投放量等，不仅能够增加衣物的洗涤效果，而且更加省水省电，更加环保，达到智能洗涤的效果。
根据本发明实施例的滚筒洗衣机100，通过精准感知被洗衣物的重量，结合滚筒洗衣机100的电脑板，准确选择相应的洗衣水位，保证洗净衣物的同时，杜绝了水资源浪费，也同样解决了洗涤剂残留严重的问题，提高了滚筒洗衣机100的智能化水平。
横梁22在箱体20内的位置可以根据滚筒洗衣机100的结构进行合理调节，可选地，根据本发明的一个实施例，横梁2设在箱体20的下部，筒体30安装在横梁22上方，霍尔传感器40设在横梁22的上表面和筒体30的下部之间。
如图1所示，在本发明的另一些具体实施方式中，横梁22设在箱体20的上部，筒体30安装在横梁22下方，霍尔传感器40设在横梁22的下表面和筒体30的上部之间。具体地，霍尔传感器40可以设在筒体30的上部和横梁22的下表面之间，横梁22的下表面形成为平面，当向滚筒洗衣机100内投放衣物时，筒体30整体向下发生位移，筒体30的底面与横梁22的下表面之间的距离变化明显，容易测量。由此，将霍尔传感器40设在筒体30的上部和箱体20的横梁22之间，不仅装配方便，而且可以更加准确地感测筒体30与横梁22的相对位移。
如图2所示，根据本发明的一个实施例，霍尔传感器40包括固定端41和移动端42。具体地，固定端41设在筒体30和横梁22的一个上，移动端42设在筒体30和横梁22的另一个上，固定端41和移动端42之间相对运动产生电信号。固定端41和移动端42通过导线与控制器50相连以实现电信号传递。
也就是说，霍尔传感器40包括两个互相配合的元件，霍尔传感器40通过两个元件之间的配合，例如相对位置发生变化，产生电信号。其中，固定端41和移动端42中的一个设在筒体30上，另一个设在横梁22上，设在筒体30上的元件随着筒体30的移动而在上下方向上产生位移，设在横梁22上的元件则相对静止。
固定端41和移动端42的一个相对静止，另一个发生相对运动，无论是固定端41发生运动还是移动端42发生运动，固定端41与移动端42之间会产生相对运动，使得固定端41与移动端42相对位移并切割移动端42的磁场，进而产生电信号。其中，固定端41的具体结构以及固定端41切割移动端42的磁场产生电信号的原理对于本领域技术人员来说 是可以理解并且容易实现的，因此不再详细描述。
霍尔传感器40在横梁22和筒体30之间的装配位置可以根据需要进行合理调节，可选地，在本发明的一些具体实施方式中，固定端41设在横梁22上，移动端42设在筒体30的上部。也就是说，移动端42设在筒体30上，并随着筒体30在上下方向上的移动发生位移，固定端41在横梁22上相对静止。固定端41相对于移动端42发生位移，固定端41发生位移过程中切割移动端42的磁场，从而产生电信号。
根据本发明的一个实施例，固定端41上设有棱柱411，棱柱411上绕设有磁感线圈，移动端42上设有两个磁性件421，两个磁性件421在左右方向上间隔开平行分布，棱柱411设在两个磁性件421之间。由此，两个磁性件421之间可以产生磁场，棱柱411上设有磁感线圈，棱柱411在两个磁性件421之间可移动以切割磁场，该结构的固定端41和移动端42在横梁22和筒体30上装配方便，并且容易配合产生电信号。
磁性件421的选择没有特殊限制，只要满足能够与棱柱411上的磁感线圈配合产生电信号的要求即可，可选地，根据本发明的一个实施例，磁性件422为磁铁，两个磁铁分别沿上下方向延伸且两个磁铁的N极和S极的位置相反。
换言之，移动端42包括两个在左右方向上间隔开且平行设置的磁铁，并且两个磁铁的N极和S极位置相反，即一个磁铁的N极朝上，S极朝下，另一个磁铁的N极朝下，S极朝上。棱柱411设在两个平行设置的磁铁之间且分别与两个磁铁间隔开设置，棱柱411相对于磁性件421在方向上可移动，从而可以切割两个磁性件421之间产生的磁场，产生电信号。
由此，该固定端41和移动端42结构简单，不仅便于在滚筒洗衣机100上进行装配，而且也便于产生磁场，进而方便固定端41和移动端42配合产生电信号。另外，磁铁来源广泛，成本低廉，有利于降低滚筒洗衣机100的整体制备成本。
根据本发明实施例的滚筒洗衣机100的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
