Description

具有称重功能的冲奶机及其控制方法 技术领域
本发明涉及一种冲奶机，特别是一种有称重功能的冲奶机及其控制方法。
背景技术
目前市场上配方奶粉的种类繁多，且各个种类中又含有不同的适用年龄阶段的配方奶粉，配方奶粉不同种类、不同阶段中，其冲泡的配方几乎都不相同，因此，使用现有自动冲奶机时，都需要根据所冲泡的奶粉的配方向自动冲奶机输入相应的冲泡参数，然后自动冲奶机根据相关参数自行调配水和奶粉的比例。而目前的自动冲奶机对奶粉的投放控制一般有两种，一种是根据送粉电机旋转的圈数来确定投放奶粉的体积，另一种是根据送粉电机旋转的时间来确定投放奶粉的体积，至于单位体积中奶粉的重量是多少，则根据配方奶粉的种类和阶段而定。因此，自动冲奶机的控制程序中需要将奶粉的冲泡数据录入，而生产厂家一般只对控制程序中录入一些常用品牌的奶粉冲泡数据，对于其它品牌的奶粉冲泡数据，作为有良心的厂家，一般在用户提出要求后，根据用户提供的奶粉品牌自行购买该奶粉后，通过实验测量其与该自动冲奶机相应的冲泡数据后，录入到手机APP控制程序中，用户即可通过手机控制自动冲奶机冲奶，或者，通过联网、刷程序等方式录入到自动冲奶机控制程序中，自动冲奶机即可通过相应的数据冲泡出符合配方要求的奶液。
另外，目前自动冲奶机的质量好坏主要体现在自动加水量的精准度、水加热温度的精准度、自动投奶粉量的精准度以及水粉混合充分度这几方面。由于婴儿奶粉冲泡时水温、水量、奶粉量的关系要求比较严格，否则容易导致婴儿肠胃不适、营养不良、营养过剩等。其中，按照目前的加工技术，水加热温度的精准度(具有温度传感检测)、自动加水量的精准度(通过流量计可以准确计算水的容积)和水粉混合充分度是比较容易保证的，而自动投奶粉量的控制则成为重点。
发明内容
本发明的目的在于提供一种结构简单、合理，可测量供水和奶粉实际输出量的有称重功能的冲奶机及其控制方法，以克服现有技术的不足。
本发明的目的是这样实现的：
一种具有称重功能的冲奶机，包括机体、控制电路板、供水机构和投粉机构，控制电路板、供水机构和投粉机构分别设置在机体上，供水机构和投粉机构分别与控制电路板电性连接，其特征在于：所述机体上还设置有用于测重的称重传感器，称重传感器与控制电路板电性连接。
本发明的目的还可以采用以下技术措施解决：
作为更具体的方案，所述称重传感器上设有容器承放板，容器承放板与机体隔开。
所述机体上还设有冲泡混合器，冲泡混合器内设有混合腔，混合腔底部设有出液口，称重传感器位于出液口下方；所述供水机构设有出水口，投粉机构设有投料口，出水口和投料口分别与混合腔连通。
所述供水机构中设有用于监测出水口水流出量的流量计，流量计与控制电路板电性连接。
所述供水机构包括储水箱、水泵、水加热器和所述流量计，水加热器设有入水口和所述出水口，入水口通过水泵、流量计与储水箱连通，水泵、流量计和水加热器分别与控制电路板电性连接。
所述投粉机构包括料杯、搅拌桨、刮粉桨、投粉桨、传动轴和投粉驱动电机，搅拌桨、刮粉桨和投粉桨从上至下依次设置在料杯内，刮粉桨与料杯固定连接，传动轴下端与投粉驱动电机传动连接，传动轴上端从料杯底部伸入料杯内与搅拌桨和投粉桨传动连接，投粉驱动电机与控制电路板电性连接；所述投料口设置在料杯底部，投粉桨对应投料口设有奶粉格，奶粉格行走至投料口上时，奶粉格中奶粉将会掉出投料口外。
所述机体对应储水箱设有水位检测装置。所述投粉机构还包括奶粉量检测装置。水位检测装置和奶粉量检测装置均为现有技术，本公司之前申请的专利中均有说明，再次不再详述。
所述供水机构还包括用于对储水箱内水进行杀菌的紫外光 杀菌灯和/或用于对储水箱内水进行过滤的过滤器，紫外光杀菌灯与控制电路板电性连接。通过加装对储水箱中水进行处理的紫外光杀菌灯和/或过滤器后，可以提升水的质量，其中，紫外光杀菌灯可以杀灭水中的一部分细菌，而过滤器可以过滤水中杂质，使得冲泡的奶液对婴儿更有利。
所述冲泡混合器为预制一次性漏斗，预制一次性漏斗承接在机体上，预制一次性漏斗内部形成所述混合腔，混合腔顶部敞开构成所述进料口和进水口，预制一次性漏斗下端出口为所述出液口。预制一次性漏斗可以是由纸、塑料膜、铝箔等轻质薄壁材料制成，当冲奶时放置在机体上，冲完奶后可以即时取出抛弃，达到不用清洗冲泡混合器的目的；当然，如果预料在短时间内将会再次冲奶，也可以暂时不抛弃预制一次性漏斗，等短期内用完再抛弃(即预制一次性漏斗所指的含义是制造成本及材料成本很低，可以是一次或者短时间内连续使用几次即可抛弃)。
一种具有称重功能的冲奶机的控制方法，其特征在于：具有称水模式，当执行称水模式时，控制电路板检测称重传感器上是否放置容器以及检测储水箱水位是否足够执行称水模式，若以上条件符合，控制电路板将称重传感器测得数据清零，并启动水泵向容器供水至流量计产生一定的脉冲数量N1，然后测出容器中水的重量T1，通过T1/N1得出每一脉冲对应的实际出水重量W1，并且将W1替代控制板预设的每一脉冲对应的预计出水重量W0作为以后供水参考值；以上称水模式可以定期执行，或者，只有上电后执行一次。
称水模式执行完毕后，提示冲奶模式或直接进入冲奶模式，或者称水模式执行完毕后用户根据需要选择冲奶模式；当执行冲奶模式时，控制电路板检测称重传感器上是否放置容器、检测储水箱水位是否足够执行冲奶模式以及奶粉量是否足够执行冲奶模式，若以上条件符合，控制电路板将称重传感器测得数据清零，并启动投粉驱动电机及水泵，分别向容器投放N2次奶粉和一定重量的水W2，W2是以W1作为参考计算出来，其中，投放N2次奶粉的预设重量为T2，然后通过测出奶水总重量M1后，控制电路板程序减去W2，即可计算出实际投奶粉重量为T3， 进一步通过计算即可得出要实际要投放次才能获得T2重量的奶粉，N3＝T2/(T3/N2)，同时将N3替代N2。
一种具有称重功能的冲奶机的控制方法，其特征在于：具有称奶模式，当执行称奶模式时，控制电路板检测称重传感器上是否放置容器以及检测料杯奶粉量是否足够执行称奶模式，并提示取走冲泡混合器，若以上条件符合，控制电路板将称重传感器测得数据清零，并启动投粉驱动电机，向容器投放N2次奶粉,其中,投放N2次奶粉的预设重量为T2，然后通过称出实际投奶粉重量为T3，进一步通过计算即可得出要实际要投放N3次才能获得T2重量的奶粉,N3＝T2/(T3/N2),同时将N3替代N2作为以后投奶粉参考；以上称奶模式可以定期执行，或者，只有上电后执行一次。
称奶模式执行完毕后，提示冲奶模式或直接进入冲奶模式，或者称水模式执行完毕后用户根据需要选择冲奶模式；当执行冲奶模式时，控制电路板检测称重传感器上是否放置容器、检测储水箱水位是否足够执行冲奶模式以及奶粉量是否足够执行冲奶模式，若以上条件符合，控制电路板将称重传感器测得数据清零，并启动水泵及投粉驱动电机，分别向容器供一定重量W3的水和投放一定重量T4的奶粉，T4是以N3作为参考计算出来，其中，供水重量W3是根据供水预设值计算出来的，供水预设值为流量计每一脉冲相应出水重量W0；最后，通过测出奶水总重量M1后，控制板程序减去T4，即可计算出实际供水重量为W4，进一步通过计算即可得出流量计每产生一脉冲实际获得W5重量的水，W5＝W4/(W3/W0)，同时将W5替代W0。W3/W0可得出产生的脉冲数。
本发明的有益效果如下：
(1)此款具有称重功能的冲奶机的称重传感器与控制电路板的结合，还可以具有其它的衍生功能，例如测量出水、出奶粉等实际参数，从而指导冲奶时能够准确供水及投奶粉。
(2)此款具有称重功能的冲奶机通过设计控制电路板的程序，可以实现通过称重传感器感知容器的存在，而取消传统的红外检测容器存在，以避免成本的增加。

具体实施方式
下面结合附图及实施例对本发明作进一步描述。
实施例一，参见图1-图3所示，一种具有称重功能的冲奶机，包括机体4、控制电路板、供水机构和投粉机构2，控制电路板、供水机构和投粉机构2分别设置在机体4上，供水机构和投粉机构2分别与控制电路板电性连接，所述机体4上还设置有用于测重的称重传感器8，称重传感器8与控制电路板电性连接。
所述称重传感器8上设有容器承放板5，容器承放板5与机体4隔开。所述称重传感器8可以是压力传感器、重力传感器等。
所述机体4上还设有冲泡混合器3，冲泡混合器3内设有混合腔33，混合腔33底部设有出液口32，称重传感器8位于出液口32下方；所述供水机构设有出水口，投粉机构2设有投料口29，出水口和投料口29分别与混合腔33连通。所述冲泡混合器3外设有托架31，冲泡混合器3通过托架31与机体4连接。
所述供水机构中设有用于监测出水口水流出量的流量计9，流量计9与控制电路板电性连接。
所述供水机构包括储水箱1、水泵6、水加热器7和所述流 量计9，水加热器7设有入水口和所述出水口，入水口通过水泵6、流量计9与储水箱1连通，水泵6、流量计9和水加热器7分别与控制电路板电性连接。
所述投粉机构2包括料杯22、搅拌桨25、刮粉桨26、投粉桨27、传动轴28和投粉驱动电机10，搅拌桨25、刮粉桨26和投粉桨27从上至下依次设置在料杯22内，刮粉桨26与料杯22固定连接，传动轴28下端与投粉驱动电机10传动连接，传动轴28上端从料杯22底部伸入料杯22内与搅拌桨25和投粉桨27传动连接，投粉驱动电机10与控制电路板电性连接；所述投料口29设置在料杯22底部，投粉桨27对应投料口29设有奶粉格，奶粉格行走至投料口29上时，奶粉格中奶粉将会掉出投料口29外。
所述搅拌桨25顶部固定连接有拆装臂21，拆装臂21延伸至料杯22的内上部。所述搅拌桨25通过其中心与传动轴28旋扣连接或螺纹连接，拆装臂21上下两端分别为一体连接的把手位211和座台212，座台212与搅拌桨25中心顶部固定连接。所述拆装臂21的把手位211呈扁平状，座台212与搅拌桨25超声波焊接固定或通过连接件固定。通过在搅拌桨25顶端固定设置拆装臂21后，由于拆装臂21延伸至料杯22的内上部(超过奶粉最高放置位置)而不被奶粉遮盖，当奶粉遮盖搅拌桨25时，也能便于用户通过捏住拆装臂21后旋转搅拌桨25实现搅拌桨25的拆卸。
所述机体4对应储水箱1设有水位检测装置。所述投粉机构2还包括奶粉量检测装置。
控制方法实施方式一，结合图4所示，一种具有称重功能的冲奶机的控制方法，上电提示称水模式，或者，上电后直接进入称水模式，或者，上电后用户根据需要选择称水模式。当执行称水模式时，控制电路板检测称重传感器8上是否放置容器以及检测储水箱1水位是否足够执行称水模式，若以上条件符合，控制电路板将称重传感器8测得数据清零，并启动水泵6向容器供水至流量计9产生一定的脉冲数量N1，然后测出容器中水的重量T1，通过T1/N1得出每一脉冲对应的实际出水重量W1，并且将W1替代控制板预设的每一脉冲对应的预计出水重量 W0作为以后供水参考值；以上称水模式可以定期执行，或者，只有上电后执行一次。当不执行称水模式时，根据用户输入命令工作，并且按照流量计每一脉冲对应的预计出水重量W0控制出水；当然，如果出厂时没有对流量计每一脉冲对应的预计出水重量进行设置时，则上电后必定需要执行称水模式。
控制方法实施方式二，与控制方法实施方式一的区别在于：结合图5所示，称水模式执行完毕后，提示冲奶模式或直接进入冲奶模式，或者称水模式执行完毕后用户根据需要选择冲奶模式；当执行冲奶模式时，控制电路板检测称重传感器8上是否放置容器、检测储水箱1水位是否足够执行冲奶模式以及奶粉量是否足够执行冲奶模式，若以上条件符合，控制电路板将称重传感器8测得数据清零，并启动投粉驱动电机10及水泵6，分别向容器投放N2次奶粉和一定重量的水W2，W2是以W1作为参考计算出来，其中，投放N2次奶粉的预设重量为T2，然后通过测出奶水总重量M1后，控制电路板程序减去W2，即可计算出实际投奶粉重量为T3，进一步通过计算即可得出要实际要投放次才能获得T2重量的奶粉，N3＝T2/(T3/N2)，同时将N3替代N2。
如果不执行冲奶模式，控制电路板根据用户输入命令工作，并且按照出奶粉预设定值(T2/N2)出奶粉。
控制方法实施方式三，结合图6所示，一种具有称重功能的冲奶机的控制方法，上电提示称奶模式，或者，上电后直接进入称奶模式，或者，上电后用户根据需要选择称奶模式。当执行称奶模式时，控制电路板检测称重传感器8上是否放置容器以及检测料杯22奶粉量是否足够执行称奶模式，并提示取走冲泡混合器3，若以上条件符合，控制电路板将称重传感器8测得数据清零，并启动投粉驱动电机10，向容器投放N2次奶粉,其中,投放N2次奶粉的预设重量为T2，然后通过称出实际投奶粉重量为T3，进一步通过计算即可得出要实际要投放N3次才能获得T2重量的奶粉,N3＝T2/(T3/N2),同时将N3替代N2作为以后投奶粉参考；以上称奶模式可以定期执行，或者，只有上电后执行一次。当不执行称奶模式时，控制电路板根据用户输入命令工作，并且按照出奶粉预设定值(T2/N2)出奶粉。当然， 如果出厂时没有设置奶粉预设定值，，则上电后必定需要执行称奶模式。
控制方法实施方式四，与控制方法实施方式三的区别在于：结合图7所示，称奶模式执行完毕后，提示冲奶模式或直接进入冲奶模式，或者称水模式执行完毕后用户根据需要选择冲奶模式；当执行冲奶模式时，控制电路板检测称重传感器8上是否放置容器、检测储水箱1水位是否足够执行冲奶模式以及奶粉量是否足够执行冲奶模式，若以上条件符合，控制电路板将称重传感器8测得数据清零，并启动水泵6及投粉驱动电机10，分别向容器供一定重量W3的水和投放一定重量T4的奶粉，T4是以N3作为参考计算出来，其中，供水重量W3是根据供水预设值计算出来的，供水预设值为流量计9每一脉冲相应出水重量W0；最后，通过测出奶水总重量M1后，控制板程序减去T4，即可计算出实际供水重量为W4，进一步通过计算即可得出流量计9每产生一脉冲实际获得W5重量的水，W5＝W4/(W3/W0)，同时将W5替代W0。
如果不执行冲奶模式，控制电路板根据用户输入命令工作，并且按照流量计每一脉冲对应的预计出水重量W0控制出水。
结合图13所示，为本实施例的具体控制方案，控制面板具有四个功能按键，分别为：“冲奶”按键、“冲水”按键、“设置”按键、“自清洗”按键。功能按键区的灯为LED散光白色灯珠(可选择贴片灯)，显示屏区WIFI指示灯双色灯。按键声音全为和弦音或多媒体声音，声音分：开机音、按键音、无效声、报警音。按键方式为触摸感应方式，以手指轻触为执行动作，手指接触到触摸键时声音响起(长按的手接触按键开始算时间，时间到声音响起)，手指离开触摸键时开始执行命令。
机器每一次上电后，进入待机状态，唤醒后需要操作一次“自清洗”功能后才可以进行其他功能操作。
首次上电后，“4个灯”灯50％长亮(根据实际待机功率定义亮度),其他灯灭，伴随开机音；此状态为待机状态。
待机状态下，在以下两种状况下会进入唤醒状态，只有唤醒状态才能进行下一步工作
1)、触按任意按键，进入唤醒状态；
2)、电子称有计重时，进入唤醒状态；
伴随按键音进入唤醒状态后，显示屏亮，机器自动记忆上一次手动操作时的显示界面，此时可显示分为以下四种状况：
断电前为冲奶操作，断电后再上电后的待机状态在唤醒后，“冲奶”“设置”“夜光灯”灯全亮，“自清洗”灯慢闪，“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲奶时对应的温度和水量，每隔2s自动切换。
断电前为冲水操作，断电后再上电后的待机状态在唤醒后，“冲水”“设置”“夜光灯”灯全亮，“自清洗”灯慢闪，“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲水时对应的温度和水量，每隔2s自动切换。
冲完奶后30秒无操作后进入的待机状态，经唤醒后，“冲奶”“设置”“夜光灯”灯全亮；“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲奶时对应的温度和水量，每隔2s自动切换。
冲完水后30秒无操作后进入的待机状态，经唤醒后，“冲水”“设置”“夜光灯”灯全亮；“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲水时对应的温度和水量，每隔2s自动切换。
断电然后上电唤醒后的两种状态均需要进行自清洗后才能操作，按“自清洗”键后，冲水灯快闪，正常水温冲水约120ml；自清洗过程不能停止，清洗完后对应显示上电前的显示界面，但“自清洗”灯灭。自清洗完成后的状态或不断电无操作进入地状态为正常状态。
每次断电后再上电后需强制执行一次完整过程的自清洗模式方可进入正常状态。
另：此模式下，主要为校正流量计每个脉冲下的出水值：
1)电子称有计重时电子称清0，自清洗开始后至电子称有计数时，水泵暂停0.5秒(根据实际情况定)不工作，称重计再清0；
2)电路程序内定一个定量脉冲数：先设定500(根据实际情况定)脉冲给到流量计开始出水，同时重力传感器计算出水重量。通过计算：
出水重量/脉冲数＝脉冲(g/500)；电路把计算的结果代入流量计的定值，之后每次根据自清洗后测试出的数值代替之前的数值。
“冲奶”灯亮为冲奶模式，有以下四种方式进入冲奶模式
1)断电前为冲奶操作，断电后再上电后的待机状态在唤醒后，进入冲奶模式。
2)冲完奶后30秒无操作后进入的待机状态，经唤醒后进入冲奶模式。
3)断电前为冲水操作，断电后再上电后完成自清洗后，按“冲奶”键进入冲奶模式。
4)冲完水后30秒无操作后进入的待机状态，经唤醒后按“冲奶”键进入冲奶模式。
以上方式进入冲奶模式后“冲奶”、“设置”、“夜光灯”灯全亮，“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲奶时对应的温度和水量，每隔2s自动切换；“温度℃”亮时或水量ML”亮时，“+”、“-”禁用，只有当按“设置”键后，依次“水量ML”灯(首次按设置键)、温度℃”灯、和“浓度g/60ML”灯切换，此时“+”“-”可使用调整数值；
第1)种方式经完成自清洗工作后，点击“冲奶”键冲奶灯闪烁，执行冲奶命令；第2)种方式点击“冲奶”键冲奶灯闪烁，执行冲奶命令；第3)4)种方式点击“冲奶”键后进入冲奶模式后，再点击“冲奶”键冲奶灯闪烁，执行冲奶命令；长按无效。工作过程中其他操作无效，但可按冲奶键停止冲奶工作。其中，冲奶机出厂时，浓度预设值为0，当消费者使用机器时，进入冲奶模式后，系统自动判断当前浓度值，如为0时，设置键快闪，按“设置”键可切换至浓度键(不按)，LED屏中“小数点”灯亮，”+””-”调节，可根据奶粉罐的建议值输入(60ml水建议使用的奶粉值)，精确至小数点1位。当系统自动判断当前浓度值不为0时，但是正预备更换奶粉，需按“设置”键切换至“浓度g/60ML”灯设置新的浓度值。
“冲水”灯亮为冲奶模式，有以下四种方式进入冲奶模式
1)断电前为冲水操作，断电后再上电后的待机状态在唤醒后，进入冲水模式。
2)冲完水后30秒无操作后进入的待机状态，经唤醒后进入冲水模式。
3)断电前为冲奶操作，断电后再上电后完成自清洗后，按“冲水”键进入冲水模式。
4)冲完奶后30秒无操作后进入的待机状态，经唤醒后按“冲水”键进入冲水模式。
以上方式进入冲水模式后“冲水”、“设置”、“夜光灯”灯全亮，“温度℃”灯和“水量ML”灯交替亮，LED对应显示上次冲水时对应的温度和水量，每隔2s自动切换；切换状态中“温度℃”灯或“水量ML”灯亮，“+”、“-”均禁用，只有当按“设置”键后，依次“水量ML”灯(首次按设置键)、温度℃”灯、和“浓度g/60ML”灯切换，此时“+”“-”可使用调整数值。
第1)种方式经完成自清洗工作后，点击“冲水”键冲水灯闪烁，执行冲水命令；第2)种方式点击“冲水”键冲奶灯闪烁，执行冲水命令；第3)4)种方式点击“冲水”键后进入冲水模式后，再点击“冲水”键冲水灯闪烁，执行冲水命令；长按无效。工作过程中其他操作无效，但可按冲水键停止冲水工作。
冲水模式下按“设置”键，可依次切换“水量ML”(第一次按时切换)灯，“温度℃”灯进行设置，LED同步记忆显示上次输入值，“+”“-”键可操作，冲奶模式按“设置”键，可依次切换切换“水量ML”，“温度℃”，“浓度g/60ML”进行设置，“+”“-”键可操作。
温度：可调40-70℃，按一下递增或递减1℃，长按不动则以5℃递增或递减(间隔0.2S递增或递减1次)，直至最大或最小值，不可以循环逆数。每次设置的温度值变化伴随按键音。
水量：可调30-240ml，按一下递增或递减5ml，长按不动则以15ml递增或递减(间隔0.2S递增或递减1次)，直至最大或最小值，可以循环逆数。每次设置的水量值变化伴随按键音。
浓度：可调0-19.9，按一下递增或递减0.1g，长按不动则以1g递增或递减(间隔0.2S？递增或递减1次)，直至最大或最小值，可以循环逆数。每次设置的浓度值变化伴随按键音。
长按“设置”键5S后进入WIFI配置模式，WIFI灯红光闪 烁搜索WIFI信号，白光快闪烁找到网络，白光慢闪烁进行与服务器连接。红光长亮30S代表配置失败；白光常亮代表连接成功并正常。网络闪断不超10S时应自动连接。失去网络后，红光长亮30S灯灭。
改产品还带有自计算粉量逻辑的功能，其操作的顺序如下：1、预设下粉为10格；2、预设浓度为10g/60ml；3、预设冲奶水量为60ml实际奶水共68g，耗时10s，每格1；4、实际下粉量＝6/10＝0.6g/格,流量6ml/s,1格/s；5、实际下粉量＝6/10＝0.6g/格,流量6ml/s；6、代入数值，下粉需10/0.6＝17格。系统自动根据每次每格奶粉的下粉量的实际值代入程序中更新自动校正下一次下粉的粉量。
报警状态：显示闪烁，模式灯闪烁，按模式键解除报警或满足解除报警条件后恢复正常状态。其他按键无效，不延续未动作完的工作。
