本发明属于电器制造技术领域，尤其涉及一种洗碗机的进水控制方法，以及一种洗碗机的进水控制***及具有该***的洗碗机。
背景技术
洗碗机是一种可以洗涤餐具上的污物，通过进水加热后进行洗涤漂洗来清洗污物的电器。洗碗机通过进水阀进水，采用流量计来测量进水量。
通过地，流量计可以包括旋转体和固定的磁铁，以及检测旋转数的流量检测部和检测磁铁随旋转体旋转时反复的开关量的电子开关。电子开关将流量计输出的信号作为输入信号，计数达到设定的开关量的值则控制进水阀停止进水，即言，流量计达到设定的计数值会控制进水阀停止进水。
图1为洗碗机进水控制的流程图。如图1所示，进水控制过程具体包括：
S010，进水阀打开，向洗碗机内进水。
S020，因为有水流，流量计的旋转体旋转。
S030，因为流量计的旋转体旋转，电子开关反复的开和闭，并产生输出信号。
S040，微处理器将流量计的输出信号作为输入信号并计算脉冲值。
S050，在脉冲计数达到设定值时，进水控制部控制进水阀关闭。
S060，停止向洗碗机内进水。
以上控制过程，根据流量计的计数信号控制进水量，会因为供水水压、进水阀的机械偏差或者流量计的机械偏差导致进水量不精确，进水水量超出设定值或者少于设定值，因而对清洗性能造成影响以及浪费能耗。

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。
针对进水流量控制不精确的问题，为了减少因为水压不稳定产生的进水偏差，进水阀的静压作用不足而产生的流量偏差，以及流量计的机械误差带来的流量偏差，本申请提出一种洗碗机的进水控制方法以及进水控制***和洗碗机，可以比较准确地供水，降低流量偏差对洗涤性能和噪音的影响，减少能量消耗。
下面参照附图描述根据本发明实施例提出的洗碗机的进水控制方法。
图2是根据本发明的一个实施例的洗碗机的进水控制方法的流程图，如图2所示，该进水控制方法包括以下步骤：
S1，控制洗碗机的进水阀开启，并控制流量计实时检测流量。
S2，获取流量计的检测值，并记录进水时间，即进水阀的开启时间。
S3，获得在流量计的检测值达到预进水阈值时的预进水时间。
具体而言，实时监测流量计的检测值，在流量计的检测值达到预进水阈值时，获得此时的进水时间即预进水时间。可以理解的是，通过预进水时间可以判断进水量的多少，而预进水时间受到进水水压、进水阀的流量偏差以及流量计的机械偏差的影响。其中，预进水阈值可以根据具体情况进行设定。
S4，根据预进水时间确定所需进水流量对应的流量计的进水终止阈值。
可以理解的是，由于预进水时间受到流量偏差的影响，对于不同的流量偏差获得的预进水时间也是不同的，根据预进水时间确定不同的进水终止阈值，换句话说，根据预进水时间确定对应当前流量偏差下的所需进水流量对应的流量计的进水终止阈值，进而在流量计的检 测值达到该进水终止阈值时，停止进水，可以达到补偿流量偏差的目的，降低流量偏差对进水流量的影响。其中，进水终止阈值可以理解为，对应当前流量偏差(可以通过预进水时间反应)、达到所需洗涤用水流量、需要流量计的检测值达到的下限值。
具体来说，可以根据预进水时间查询对应关系表格确定进水终止阈值，其中，对应关系表格为预进水时间与进水终止阈值的关系表，该关系表可以预先测定。
S5，当流量计的检测值达到进水终止阈值时，控制进水阀关闭，从而可以获得所需要的清洗用水，避免进水偏多或偏少而影响洗涤性能。
可以看出，本发明实施例的洗碗机的进水控制方法，先进行预进水，获得预进水时间，由于预进水时间与流量偏差有关，根据预进水时间确定对应所需进水流量对应的流量计的的进水终止阈值，并在流量计的检测值达到该进水终止阈值时停止进水，从而可以补偿流量偏差，进水流量控制更加精确，降低因流量偏差对洗涤性能影响，以及避免因进水量不合适而增大噪声，减少能耗。
在本发明的一些实施例中，流量计检测进水流量并输出脉冲信号，且脉冲信号作为检测值；预进水时间可以为流量计输出的脉冲信号达到预设的预进水脉冲数量时的进水时间，实时监测流量计输出的脉冲信号的计数，在流量计输出的脉冲信号的数量达到预进水脉冲数量时，获得当前的进水时间即得预进水时间。例如，流量计检测到开始供水之后开始计算脉冲值，先检测达到150个脉冲所花费的时间即预进水时间，预进水时间可以反映进水量的多少。进而，根据预进水时间确定所需进水流量对应的流量计的进水终止脉冲数量，并在流量计输出的脉冲数量达到终止脉冲数量时控制进水阀关闭，即言，根据预进水时间选择不同的最终的脉冲计数，从而可以达到补偿偏差流量的目的。
相较于相关技术，对于在供水压力、进水阀进水或流量计检测等各个环节产生的流量偏差不进行流量补偿，本发明实施例的进水控制方法，通过预进水来判断，也就是对于不同的流量偏差选择流量计的最终检测值，进而根据确定的最终检测值控制进水，从而可以补偿偏差流量。
进一步来说，为了保证进水达到所需用水量，在本发明的一些实施例中，上述进水控制方法还包括：判断是否为初次进水；如果是初次进水，则进水终止阈值增加补水阈值以作为最终的进水终止阈值；当流量计的检测值达到最后的进水终止阈值时，控制进水阀关闭。
图3是根据本发明的一个具体实施例的洗碗机的进水控制方法的流程图，如图3所示，具体包括：
S301，控制进水阀开启，向洗碗机内进水。
S302，流量计检测流量并输出脉冲信号。
S303，计算脉冲数量。
S304，判断脉冲数量是否达到预进水阈值例如150，如果达到，则进入步骤S305，否则返回步骤S303。
S305，获得脉冲计数达到150时的预进水时间，并根据预进水时间选择进水终止脉冲数量。
S306，判断是否为初次进水，如果是，则进入步骤S309，否则进入步骤S307。
S307，判断脉冲计数是否达到进水终止脉冲数量，如果是，则进入步骤S308，否则继续本步骤。
S308，控制进水阀关闭以停止进水。
S309，将进水终止脉冲数量增加补充阈值作为最终的进水终止阈值，即将选择的进水量再增加一定量，以满足洗涤需求。
S310，判断脉冲数量是否达到最终的进水终止阈值，如果是，则进入步骤S308，反之，继续本步骤。
通过初次进水的判断，可以在初次进水时进行用水补偿，满足用水需求。
另外，还可以进行故障判断，具体地，上述进水控制方法还包括：判断进水时间是否达到进水时间阈值；如果进水时间达到进水时间阈值，则进一步判断流量计的检测值是否达到预进水阈值；如果流量计的检测值未达到预进水阈值，则确定进水异常。
图4是根据本发明的另一个具体实施例的进水控制方法的流程图，如图4所示，具体包括：
S401，控制进水阀开启，向洗碗机内进水。
S402，流量计检测流量并输出脉冲信号，并记录进水时间。
S403，进行脉冲计数。
S404，判断脉冲数量是否达到预进水阈值例如150，如果达到，则进入步骤S405，否则返回步骤S403。
S405，获得脉冲计数达到150时的预进水时间，并根据预进水时间选择进水终止脉冲数量。
S406，判断流量计的脉冲数量是否达到进水终止脉冲数量，如果达到，则进入步骤S407，否则进入步骤S408。
S407，控制进水阀关闭，停止进水。
S408，判断进水时间是否达到进水时间阈值，如果达到，则进入步骤S409，否则，返回步骤S406。
S409，判断进水异常，进行报警。
总而言之，本发明实施例的洗碗机的进水控制方法，根据流量计的检测值达到设定的预 进水阈值例如150的进水时间来选择进水终止阈值，根据进水终止阈值控制进水量，其中，进水终止阈值例如进水终止脉冲数量的设置是根据进水压力、时间、流量的特性曲线预先设定的。例如分为4个水量档位，是根据获得的预进水时间不同，设置的进水终止脉冲数量不同，进而根据进水终止脉冲数量控制进水阀。
例如，以洗涤水量为4.0升为基准，流量计的输出脉冲计数达到150时的进水时间即预进水时间为t，预进水时间t会因为水压、进水阀进水、流量计的机械误差而不同，根据获得的预进水时间的不同，将进水终止脉冲数量的基准值分为1-4个档位，预进水时间与进水终止脉冲数量的对应关系如表1所示：
表1
预进水时间(秒) 进水终止脉冲数量(脉冲)
t≤19 442
19<t≤24 436
24<t≤38 426
38<t 411
其中，如果为初次进水时，进水终止脉冲数量需要增加补水阈值，即需要在选择的档位的基础上增加进水量，例如，进水量为设定水量L1+补水水量(0.21-0.31)升，例如，进水量＝4.0升+0.25升＝4.25升，从而可以满足用水需求。
参照图5所示，本发明实施例的洗碗机的进水控制方法具体包括：
S501，控制进水阀开启，向洗碗机内进水。
S502，流量计检测流量并输出脉冲信号。
S503，进行脉冲计数。
S504，判断脉冲计数是否达到预进水阈值例如150，如果是，则进入步骤S505，否则返回步骤S503。
S505，获得预进水时间，并根据预进水时间确定进水终止脉冲数量即脉冲基准值也就是进水档位。
S506，判断是否为初次进水，如果是，则进入步骤S511，否则进入步骤S507。
S507，判断脉冲计数是否达到进水终止脉冲数量，如果是，则进入步骤S508，否则进入步骤S509。
S508，控制进水阀关闭，停止进水。即水量达到选定的进水档之后控制进水阀关闭，进水完成之后，执行洗涤行程或漂洗行程。
S509，判断进水时间是否达到进水时间阈值例如240秒，如果是，则进入步骤S510，否则返回步骤S507。
S510，判断进水异常。
S511，判断脉冲计数是否达到进水终止脉冲数量与补水阈值的和值，如果是，则进入步骤S508，否则，进入步骤S509。
概括来说，洗碗机在洗涤或漂洗之前进行进水控制，由于进水压力、进水阀偏差或者流量计的误差往往造成进水流量存在偏差，本发明实施例的进水控制方法，先进行预进水，在预进水阶段获得流量计的检测值达到预进水阈值(例如整体脉冲值的1/3)时的预进水时间，根据该预进水时间来了解进水情况，进而，根据预进水时间选择对应的进水终止阈值例如达到所需用水时流量计需要输出的脉冲值(例如整体脉冲值的2/3)，并在达到该进水终止阈值时，控制进水阀关闭，完成进水，从而可以对流量偏差进行补偿，满足用水需求，保证洗碗机的洗涤性能，避免因进水偏差而增大噪音，降低能耗。
下面参照附图描述根据本发明另一方面实施例提出的洗碗机的进水控制***。
图6是根据本发明的一个实施例的洗碗机的进水控制***的框图，如图6所述，该进水控制***100包括进水阀10、流量计20、获取模块30、判断模块40和控制模块50。
其中，进水阀10用于进水的开启或关闭，流量计20用于检测进水流量；获取模块30用于获取流量计20的检测值并记录进水时间，以及获得在流量计20的检测值达到预进水阈值时的预进水时间，可以理解的是，通过预进水时间可以判断进水量的多少，而预进水时间受到进水水压、进水阀的流量偏差以及流量计的机械偏差的影响。其中，预进水阈值可以根据具体情况进行设定。
判断模块40用于根据预进水时间确定所需进水流量对应的流量计20的进水终止阈值；控制模块50用于控制进水阀10开启，并控制流量计20实时检测流量，以及在流量计20的检测值大于进水终止阈值时，控制进水阀10关闭。
由于预进水时间受到流量偏差的影响，对于不同的流量偏差获得的预进水时间也是不同的，根据预进水时间确定不同的进水终止阈值，换句话说，根据预进水时间确定对应当前流量偏差下的进水终止阈值，进而在流量计的检测值达到该进水终止阈值时，停止进水，可以达到补偿流量偏差的目的，降低流量偏差对进水流量的影响。其中，进水终止阈值可以理解为，对应当前流量偏差(可以通过预进水时间反应)、达到所需洗涤用水流量、需要流量计的检测值达到的下限值。
本发明实施例的洗碗机的进水控制***，先进行预进水，获得预进水时间，由于预进水时间与流量偏差有关，判断模块40根据预进水时间确定对应的进水终止阈值，控制模块50在流量计的检测值达到该进水终止阈值时控制进水阀10关闭以停止进水，可以补偿流量偏差，进水流量控制更加精确，可以降低因流量偏差对洗涤性能影响，以及避免因进水量不合适而增大噪声，减少能耗。
具体来说，判断模块40可以根据预进水时间查询对应关系表格确定进水终止阈值，其中，对应关系表格为预进水时间与进水终止阈值的关系表，该关系表可以预先测定，参照表1所示。
进一步地，流量计20包括旋转体、固定的磁体、检测元件和电子开关，检测元件用于检测旋转体的旋转转数并输出检测信号，电子开关根据检测信号生成脉冲信号。其中，脉冲信号作为流量计的检测值，预进水时间为流量计输出的脉冲信号达到预设的预进水脉冲数量时的进水时间，以及判断模块40根据预进水时间确定所需进水流量对应的流量计20的进水终止脉冲数量，控制模块50在流量计20输出的脉冲数量达到该终止脉冲数量时控制进水阀10关闭。
例如，流量计20检测到开始供水之后开始计算脉冲值，先检测达到150个脉冲所花费的时间即预进水时间，预进水时间可以反映进水量的多少。进而，判断模块40根据预进水时间确定进水终止脉冲数量，控制模块50在流量计20输出的脉冲数量达到终止脉冲数量时控制进水阀10关闭，即言，根据预进水时间选择不同的最终的脉冲计数，从而可以达到补偿偏差流量的目的。
为了保证进水达到所需用水量，在本发明的一些实施例中，判断模块40还用于，判断是否为初次进水，并在判断是初次进水时将进水终止阈值增加补水阈值以作为最终的进水终止阈值。并在流量计20的检测值达到最终的进水终止阈值时，控制进水阀10关闭。
另外，还可以进行故障判断，具体地，判断模块40还用于，在流量计20的检测值未达到进水终止阈值时，判断进水时间是否达到进水时间阈值，并在进水时间达到进水时间阈值时，确定进水异常。
相较于相关技术，对于在供水压力、进水阀进水或流量计检测等各个环节产生的流量偏差不进行流量补偿，本发明实施例的进水控制***100，通过预进水来判断进水情况，对于不同的流量偏差选择流量计的最终检测值，进而根据确定的最终检测值控制进水，从而可以补偿偏差流量。
