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。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
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。
下面参考图1-图3描述根据本发明实施例的洗衣机1000，该洗衣机1000可以为波轮洗衣机或滚筒洗衣机，在本发明的下面描述中均以洗衣机1000为波轮洗衣机为例进行说明，值得理解的是，当洗衣机1000为滚筒洗衣机时，光电传感器4的设置位置和作用原理等与洗衣机1000为波轮洗衣机时相同，这里就不详细描述。
如图1所示，根据本发明实施例的洗衣机1000包括：机体1、光电传感器4和控制装置(图未示出)。机体1的底壁的每个拐角处均设有用于支撑机体1的底脚60。具体地，如图1所示，机体1包括箱体10、盛水桶20和脱水桶30，盛水桶20与箱体10通过四根悬挂吊杆50相连，脱水桶30可转动地设在盛水桶20内，设有脱水桶30的盛水桶20可以在箱体10内摆动，盛水桶20和脱水桶30构成机体1的洗涤桶。当脱水桶30内水和衣物的重量发生变化时，机体1的重量会发生变化。需要进行说明的是，机体1还包括驱动电机等其他结构，洗衣机1000的洗衣原理等均为本领域的技术人员所熟知，这里就不详细描述。
光电传感器4设在至少一个底脚60内，光电传感器4被构造成在机体1的重量发生变化时输出电信号。在本发明的优选示例中，每个底脚60内均设有光电传感器4，从而可以提高洗衣机1000运行的可靠性。控制装置与光电传感器4相连以接收光电传感器4传出的电信号。具体地，电信号可以是电压、电流、频率、PWM(脉冲宽度)等。在发明的一些示例中，光电传感器4还包括与控制装置相连的光电传感器导线(图未示出)。从而便于光电传感器4与控制装置相连。这里需要注意的是，光电传感器4包括弹性件，也就是说，光电传感器4自带有弹性件。
具体而言，机体1的重力可以直接传递到底脚60内，当机体1的重量发生变化时，由于光电传感器4设在底脚60内，因此机体1的重量变化可直接传递到光电传感器4上，即光电传感器4可以实时根据机体1的重量变化输出电信号，电信号可以准确地反应机体1的重量变化，控制装置接收光电传感器4传出的电信号判断机体1的重量是否发生变化。例如具体地，控制装置可以根据接收的电信号在洗衣机1000上实现衣物的精准称重等功能。
再例如控制装置可以根据光电传感器4输出的电信号进行如下判断：洗涤完成之后，排水阀打开时，随着洗涤桶内水排出，机体1重量减轻，由于排水阀排水流速变化不大，光电传感器4输出的值也为向下的线性曲线；当洗涤桶内水排完之后，机体1重量不再变化，光电传感器4输出为接近水平的直线。当控制器采集到的数据值不再发生变化或变化 很小时，即判断洗衣机排水完成，即可立即开始进行脱水动作。用这种判断方法比现有的水位光电传感器判断方法更准确，洗涤桶内水排完立刻就能感知到，即刻就能开始脱水，可以减少洗涤时间。当然值得理解的是，控制装置还可以根据采集到的机体1的重量变化判断机体1的其他运行，这里就不详细描述。
根据本发明实施例的洗衣机1000，通过将光电传感器4设在底脚60内，光电传感器4被构造成在机体1的重量发生变化时输出电信号，控制装置可以根据电信号判断机体1的重量变化，从而可以更精确地实时监测机体1的重量变化，以控制洗衣机1000更平稳地运行。
下面参考图1-图3描述根据本发明具体实施例的洗衣机1000。
如图1所示，洗衣机1000包括机体1、光电传感器4和控制装置。光电传感器4设在底脚60内。控制装置与光电传感器4相连以接收光电传感器4传出的电信号。
机体1包括箱体10、盛水桶20和脱水桶30。箱体10包括本体101、上盖102和底座103，本体101为中空且上下两端均敞开的壳体，上盖102设在本体101的上端，上盖102上设有用于盛放和拿取衣物的盛放口(图未示出)，底座103设在本体101的下端，上盖102、本体101和底座103之间限定出用于盛放盛水桶20和脱水桶30的空间。底脚60设在底座103的底壁的拐角处。
盛水桶20通过四个悬挂吊杆50与箱体10的内壁相连，每个悬挂吊杆50与箱体10以及盛水桶20之间分别通过球面铰接的方式连接。每个悬挂吊杆50内部的缓冲弹簧501及空气阻尼套502对盛水桶20的能量有一定的缓冲吸收作用，能够保证盛水桶20和脱水桶30的平稳。
光电传感器4包括：上壳体46、下壳体45、光发射端41、光接收端42和光反射面44，其中，上壳体46的底端敞开，下壳体45的顶端敞开，上壳体46外罩在下壳体45上。
上壳体46和下壳体45之间通过弹簧43相连以使得上壳体46和下壳体45之间可相对上下移动，也就是说，上壳体46可相对下壳体45上下移动，下壳体45可相对上壳体46上下移动。上壳体46的顶壁与机体1的底壁相连，下壳体45的底部穿出底脚60以适于支撑在支撑面上。当机体1的重量发生变化时，在机体1的重力作用下，上壳体46可相对下壳体45上下移动。其中需要说明的是，上述的支撑面指的是洗衣机1000的放置面例如地面。
弹簧43为具有弹性系数的线性弹簧。弹簧43的两端分别止抵在上壳体46的下表面和光反射面44的上表面上。其中值得理解的是，上壳体46和下壳体45之间还可以是通过其他弹性件相连，弹性件也可以通过其他方式与上壳体46和下壳体45相连，上壳体46和下壳体45的形状、上壳体46和下壳体45之间的配合关系不限于此，只要使得上壳体46和 下壳体45之间可相对移动即可。
光发射端41和光接收端42设在上壳体46上。光反射面44设在下壳体45上以将从光发射端41发出的光线反射回光接收端42。当然值得理解的是，光发射端41和光接收端42还可以设在下壳体45上，光反射面44设在上壳体46上以反射光线，也就是说，光发射端41和光接收端42设在上壳体46和下壳体45的其中一个上，光反射面44设在上壳体46和下壳体45的另一个上以将从光发射端41发出的光线反射回光接收端42。值得理解的是，光电传感器4内还设有与光接收端42相连的控制面板等控制元件，控制元件可将从光接收端42接收的光信号转化为电信号，该电信号与光反射面44和光发射端41(光接收端42)之间的距离d成对应关系，优选为线性对应关系。
具体而言，光发射端41发出的光线被光反射面44反射回光接收端42内，当洗衣机1000内衣服和水的重量改变时，机体1的重量发生变化，弹簧43的形变量同时发生变化，上壳体46相对下壳体45移动，光反射面44与光发射端41和光接收端42之间的距离d发生变化，即被光反射面44反射到光接收端42的光信号发生变化，从而使得从光电传感器4传输出的电信号发生变化，使得电信号可以准确地反应洗衣机1000整机重量变化。
根据本发明实施例的洗衣机1000具有以下几个优点：
1.通过设置光电传感器4，控制装置可以即时感测机体1的重量，即时判断洗衣机1000工作状态是否正常；
2.可以直接感知排水完成，立即开始排水，节省整个洗涤过程的时间；
3.可以更精准感知脱水不平衡(例如每个底脚60内的光电传感器4发出的电信号不同)，控制装置可根据感测的数值进行调整；
4.可以感测衣物的重量，实现不同衣量进不同水量；
5.可以感知衣物脱水含水率，实现衣物含水率达到要求即停止脱水，比现有的固定时间脱水更智能，更可以保证脱水完成之后衣物含水率达到用户要求。
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“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，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”可以是第一特征在第二特征正下方或斜下方，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 在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，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以及不同实施例或示例的特征进行结合和组合。
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。
