洗衣机耗水量监测方法、洗衣机及洗衣机系统 技术领域
本发明涉及洗衣机耗水耗电检测技术领域，具体地，涉及洗衣机耗水量监测方法、洗衣机及洗衣机系统。
背景技术
现有的滚筒洗衣机和全自动洗衣机均不具备洗衣耗水量的检测，用户使用某一洗衣程序洗涤结束后，也无法获知本次洗衣的耗水量，用户对于洗衣机的了解仍然停留在原有的洗涤时间、洗涤程序、洗涤水温、洗涤水位等状态上，为了帮助用户更加深入了解洗衣机，培养用户节水习惯，洗衣机增加洗衣耗水量检测是很有必要的。
洗衣机耗水量的检测，现有的方法主要是通过流量计等检测装置进行洗衣机的耗水量的检测，该种方式虽然可以更为精确的将洗衣机用水量检测出来，但本身需要洗衣机额外增加相应的硬件设备及相关电路才能满足相应需求，给洗衣机本身带来了较大成本的增加，从用户体验和洗衣机成本增加方面考虑，其性价比较低。
另外，现有的洗衣机即使能够获取洗衣过程中的耗水量，但是通常只是简单的显示在洗衣机的显示面板上，用户一般不会主动去获取该耗水量，即使用户单次获取该耗水量，也只能仅仅获取这一次的耗水量，并不能对洗衣机的长期耗水情况以及洗衣机的使用情况进行掌握，因此，并不具有实际的使用价值。
有鉴于此，特提出本发明。

附图说明
图1本发明实施例洗衣机耗水量监测方法的流程图；
图2本发明实施例一的洗衣机耗水量监测方法的流程图；
图3本发明实施例的洗衣机的耗水量监测流程图。
具体实施方式
下面结合附图对本发明的洗衣机耗水量监测方法、洗衣机及洗衣机系统进行详细描述：
本实施例的洗衣机耗水量监测方法，包括：
洗衣机执行洗衣程序，接收水位设定指令；
洗衣机执行洗衣程序，获取从开始到结束进水阀的开启时间t；
洗衣机计算进水阀的进水流量Q＝Q0+ΔQ，并计算耗水量为：W＝Qt；
其中，在正常水压、空载情况下，洗衣机进水至该水位的理论流量值为Q0、理论进水时间t0，ΔQ为流量修正值，ΔQ由时间差(t-t0)、修正系数k计算得到，修正系数k为预设的固定值。
首先，按照正常水压P0，记录进水达到设定水位L0的时间t0，设定水位对应的水量V0，该水量V0是在洗衣机空载情况下试验测得，则对应的进水流量Q0＝V0/t0；当洗衣机放有衣物时，由于不同水压会对进水流量产生影响，需要根据水压大小对进水流量进行修正补充。
本实施例的洗衣机耗水量监测方法通过检测进水阀开启的时间t，由公式W＝Qt计算出洗衣机的耗水量，而进水阀的流量Q以在正常水压、空载情况下，洗衣机进水至该水位的理论流量值Q0为基础，考虑到进水的水压以及进水阀的结构特点得到进水流量修正值ΔQ，最终计算得到进水阀进水的实际进水流量Q＝Q0+ΔQ。因此，本发明的洗衣机耗水量监测方法更符合进水阀的实际工况，计算得到的进水流量Q更为准确，与流量计测得值相差不大，使得本发明的洗衣机耗水量监测方法计算得到的耗水量在误差范围内，计算结果可靠，具有一定的参考价值。
由于洗衣机一般包括多个进水水位，每一个进水水位，对应一组理论流量值为Q0和理论进水时间t0，因此，本发明具有多组理论流量值为Q0和理论进水时间t0，当选定某一设定水位时，相应的一组理论流量值为Q0和理论进水时间t0也即被选定。
进一步地，本实施例所述的流量修正值ΔQ满足：
Figure PCTCN2017072139-appb-000004
当t＞t0时，ΔQ取正，当t＝t0时，ΔQ＝0，当t＜t0时，ΔQ取负；
其中，修正系数k是固定常数，取决于进水压强，以及进水口面积。
具体地，本实施例所述的修正系数k＝k1*k2：
所述的
Figure PCTCN2017072139-appb-000005
其中，μ为流量系数，与阀门或管子的形状有关，A为进水口的截面面积，ρ为流体的密度；
所述的k2可在设定水位的空载状态下，由不同的水压对应的进水时间t试验计算得到。
如果设定水位确定，不同水压对应的进水流量、进水时间也不相同，进水阀的流量、流速、截面积、水压之间的关系式为：
Figure PCTCN2017072139-appb-000006
其中μ为流量系数，与阀门或管子的形状有关，一般取值0.6～0.65；A为水管截面面积，单位m2；P为通过阀门 前后的压力差，单位Pa，P＝P1-P2，P1为水压，P2为标准大气压；ρ为流体的密度，单位Kg/m3；v为流速。由上述关系式可知，进水水压与流量存在正比例关系，即Q2＝k1*P，k1可以根据水龙头相关参数计算得出。
当洗衣机空载情况下水位设定为确定值时，进水水压与进水时间存在反比例对应关系，即P＝k2/t，由于空载状态下试验测得，不同的水压对应不同的时间，k2可以通过实验数据测试获得，所以Q2＝k/t，k＝k1*k2，
Figure PCTCN2017072139-appb-000007
当t＞t0时，ΔQ取正，当t＝t0时，ΔQ＝0，当t＜t0时，ΔQ取负。
因此，本实施例的进水流量Q的计算充分考虑到影响进水的因素，在理论值上进一步修正，更加接近实际的进水流量，保证了耗水量计算的准确性。
本实施例所述洗衣机的进水包括多个设定水位x，每一设定水位对应多个进水阶段y，所述的洗衣机关机或洗衣结束后的耗水量为各个阶段的耗水量之和，根据公式
W＝Qx1*Tx1+Qx2*Tx2+Qx3*Tx3+…+Qxy*Txy(Qxy表示设定水位为x对应的进水阶段y的流量，Txy表示设定水位x下进水阶段y的所有进水阀开启时间)计算洗衣的耗水量。
本实施例的洗衣机一般包括洗涤进水阶段和漂洗进水阶段，还可以包括有喷淋进水、主进水、软化进水等过程的进水，因此，本实施例的洗衣机耗水量监测方法将进水根据实际的工况分为多个进水阶段，每个进水阶段进行计算，可最大的降低误差，另外，可根据洗衣机的类型或者洗衣机的程序选择，选择相应进水阶段的进水量计算，更有利于实际工作状态下耗水量的计算。
进一步地，本实施例所述的洗衣机根据计算公式得出相应修正后各个进水阶段的进水流量Q11、Q12、Q13、…..、Qxy，
所述的Qxy＝Qx0+ΔQxy，其中Qx0表示设定水位x时，在正常水压、空载情况下，洗衣机进水至该水位的理论流量值，ΔQxy表示设定水位x时y进水阶段的进水流量偏移量。
进一步地，所述的洗衣机包括多个进水阀，分别计算每个进水阀打开时间(txy1、txy2、txy3、···、txyz)，每个进水阶段的进水阀打开时间Txy＝＝txy1+txy2+txy3+…+txyz(txyz表示设定水位x下第y个阶段的第z个进水阀的进水时间)；
所述的
Figure PCTCN2017072139-appb-000008
Txy0表示设定水位x进水阶段y时，在正常水压、空载情况下，洗衣机进水至该水位的理论进水时间，当Txy＞Txy0时，ΔQxy取正，当Txy＝Txy0时，ΔQxy＝0，当Txy＜Txy0时，ΔQxy取负。
本实施例进一步考虑到进水阀设置的数量，针对其每个进水阀单独计算，避免增大误差，同时，可根据实际洗衣程序中工作的进水阀，对其计算，灵活性更高，适应性更强，计算结果更为精准。
本实施例的设定水位x∈[1，12]，进水阶段y与用户所选择的漂洗次数有关系，进水阶段y∈[1，10]，具体的，x、y值的范围与用户所选择的漂洗次数有关系。
