具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描 述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的滚筒洗衣机1。
如图1所示，根据本发明实施例的滚筒洗衣机1包括箱体100、筒体200、吊簧300、光电传感单元400和控制器(图中未示出)。
箱体100的前表面设有衣物取放口(图中未示出)和用于打开和关闭所述衣物取放口的门体(图中未示出，其中前后方向为垂直于图1纸面的方向，朝向读者的为前，背离读者的为后)。筒体200通过吊簧300设在箱体100内。光电传感单元400邻近吊簧300设置以检测吊簧300的伸缩量。所述控制器与光电传感单元400相连，所述控制器根据光电传感单元400的伸缩量检测值判断筒体200的重量和/或位移。需要注意的是，这里的“光电传感单元”为纯光电传感元件，例如包括发射接收区、反射区；或包括发射件、接收件和反射区；也就是说，在本发明之实施例中，“光电传感单元”不自带弹簧体或类似弹簧体的部件。
下面描述根据本发明实施例的滚筒洗衣机1的称重过程。开启滚筒洗衣机1后，把需要洗涤的衣物放入筒体200中，此时由于被洗衣物的重力对筒体200起作用，筒体200会下沉，吊簧300的伸缩量发生变化，光电传感单元400对吊簧300的伸缩量进行检测并将检测结果输送至所述控制器，所述控制器根据吊簧300的伸缩量判断投放衣物的重量，使洗涤的水量、洗涤时间、洗涤剂投放量与被洗衣物对应。
根据本发明实施例的滚筒洗衣机1，通过邻近吊簧300设置光电传感单元400，利用光电传感单元400检测吊簧300的伸缩量，可以根据吊簧300的伸缩量，可以根据吊簧的伸缩量得出筒体的重量和/或位移，一方面可进一步准确计算筒体内投放衣物的重量，进而可以根据投放衣物的重量自行调节洗衣过程中的洗涤水量、洗涤时间、洗涤剂投放量等；另一方面通过获得筒体的重量和/或位移等基础数据进一步程序控制调整洗衣机振动偏移量，可使洗衣机更稳定、平稳运行。由此不仅可以提高洗涤效果，而且可以避免水电资源的浪费，更加环保。因此，根据本发明实施例的滚筒洗衣机1能够准确称重衣物的投放量，具有洗涤效果好、节省资源、环保等优点。
下面参考附图描述根据本发明具体实施例的滚筒洗衣机1。
在本发明的一些具体实施例中，如图1所示，根据本发明实施例的滚筒洗衣机1包括箱体100、筒体200、吊簧300、光电传感单元400和控制器。光电传感单元400为若干个且邻近吊簧300设置，下面以一个光电传感单元400为例进行描述。需要注意的是，这里的“光电传感单元400”为纯光电传感元件，例如包括发射接收区、反射区；或包括发射件、接收件和反射区；也就是说，在本发明之实施例中，“光电传感单元”不自带弹簧体或类似弹簧体的部件。实质上，本发明中的“光电传感单元400”与吊簧300一起组成光电 传感器。
光电传感单元400包括发射接收区410和反射区420。发射接收区410邻近吊簧300的一端设置且相对吊簧300的一端相对静止。反射区420邻近吊簧300的另一端设置且相对吊簧300的另一端静止。
发射接收区410发射光谱信号，反射区420将发射接收区410发射的光谱信号反射回发射接收区410，发射接收区410接收被反射的光谱信号并转化为电信号传输至所述控制器，所述控制器根据发射接收区410转化的电信号判断筒体200内衣物的重量。
当吊簧300的伸缩量发生变化时，由于发射接收区410相对吊簧300的一端静止且反射区420相对吊簧300的另一端静止，发射接收区410和反射区420的相对距离会发生变化，根据发射接收区410和反射区420相对距离的变化可以检测出吊簧300的伸缩量。由此可以实现光电传感单元400对吊簧300伸缩量的准确检测。
具体而言，如图1所示，发射接收区410包括发射件411和接收件412，发射件411发射光谱信号，反射区420将发射件411发射的光谱信号反射到接收件412，接收件412接收被反射的光谱信号并转化为电信号传输至所述控制器，实现发射接收区410发射和接收光谱信号以及对光谱信号的转化功能。
可选地，发射件411和接收件412邻近吊簧300的上端设置且相对吊簧300的上端相对静止，反射区420邻近吊簧300的下端设置且相对吊簧300的下端相对静止(上下方向如图1中的箭头A所示)。
在本发明的一些具体示例中，发射件411和接收件412设在箱体100的内顶面上且邻近吊簧300的上端。反射区420设在筒体200的外顶面上且邻近吊簧300的下端。由此可以使发射件411和接收件412相对吊簧300的上端相对静止，且反射区420相对吊簧300的下端相对静止。
可选地，发射件411和接收件412在箱体100的内顶面上间隔开设置。由此可以便于反射区420将发射件411发射的光谱信号反射到接收件412。
在本发明的另一些具体示例中，如图1所示，箱体100或筒体200上设有安装板600，发射件411和接收件412设在安装板600上且邻近吊簧300的上端，反射区420设在筒体200的外顶面上且邻近吊簧300的下端。由此同样可以使发射件411和接收件412相对吊簧300的上端相对静止，且反射区420相对吊簧300的下端相对静止。
可选地，发射件411和接收件412在安装板600上间隔开设置。由此可以便于反射区420将发射件411发射的光谱信号反射到接收件412。
在本发明的一些具体实施例中，如图1所示，滚筒洗衣机1还包括减震阻尼器700，减震阻尼器700的下端安装在箱体100的内底面上且上端安装在筒体200的外底面上。由此 可以利用减震阻尼器700和吊簧300共同支撑筒体200，提高对筒体200的缓冲减震效果，以提高筒体200的稳定性。
如图1所示，吊簧300为多个，多个吊簧300的下端分别连接在筒体200的外顶面的左部和右部(左右向如图1中的箭头B所示)。减震阻尼器700为多个，多个减震阻尼器700的上端分别安装在筒体200的外底面的左部和右部。吊簧300和减震阻尼器700的假想延长线均经过筒体200的横截面的圆心。换言之，多个吊簧600和多个减震阻尼器300可以从筒体200的横截面的圆心为出发点，沿筒体200的横截面的径向呈放射状排列。例如，减震阻尼器300为两个，吊簧600可以为两个。这样可以进一步提高筒体200的稳定性。
在本发明的一些具体实施例中，所述控制器为设在箱体100上的电脑板。由此可以将所述控制器集成在电脑板上，使滚筒洗衣机1的结构更加简单、控制更加方便。
根据本发明实施例的滚筒洗衣机1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。

此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特 征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
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必须针对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。此外，本领域的技术人员可以将本说明书中描述的不同实施例或示例进行接合和组合。
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。
