本申请首先提出一种用于冰箱制冰的控制方法，该冰箱内部设置有制冰机，该制冰机包括制冰格、进水装置和储冰盒等，在制冰格底部还设置有检测冰块温度的底部温度传感器。在一实施例中，如图1所示，基于上述的制冰机的制冰的控制方法包括：
步骤S100、控制制冰机工作第一时间；
步骤S200、获取制冰机的制冰格内的冰块温度；
步骤S300、判断冰块温度是否小于预设温度；以及
步骤S400、在判断出冰块温度小于预设温度的情况下，控制制 冰机继续工作第二时间以结束制冰过程。
在步骤S100中，制冰机在制冰运行时，首先控制制冰机工作第一时间进行制冰过程，这里的制冰过程具体是打开制冰机的冷气输送管路，冰箱的压缩机运行在冰箱的冷媒管路上产生冷量，通过风扇的转动在冷气输送管路形成冷气，并通过所述的冷气输送管路向制冰格输送冷气，以对制冰格中的水进行冷冻，使其逐渐转换成冰块。这里的第一时间是制冰机的基本工作时间，也即制冰机进行制冰时必须工作的基本时间，该时间由制冰机在前期研发实验过程中确定，具体根据制冰格内冰块的多少通过实验确定，如可确定为30至40分钟，以此保证制冰格能基本实现结冰。
在步骤S200至步骤S400中，在运行完成上述第一时间后，制冰机的控制器再通过设置在制冰格底部的底部温度传感器检测制冰格底部的温度，并实时判断该温度是否小于预设温度，如果小于预设温度，则认为制冰格的制冰温度满足结冰要求。
在判断输出上述冰块温度小于预设温度时，则控制制冰机再继续运行第二时间以结束制冰过程。
这里的预设温度是指判断为结冰完成的温度，根据实验确定一般为-9℃或者-10℃。
因为在底部温度传感器检测到的温度是制冰格底部安装传感器位置所在的区域的温度值，并不能完全代表整个制冰格底部的温度，制冰格中各个冰格所处的冰块温度实际是不均匀的，特别是制冰格周围的冰格冰块温度会比中间区域的高，这使得冰块温度满足了结冰要 求后，底部温度传感器所在区域的冰块结冰达到要求，但周围的冰块不一定满足要求，可能还存在结冰不完全的冰水状态，因而在冰块温度小于预设温度后，再控制制冰机运行第二时间，以使得整个制冰格的所有冰块都能完全结冰。以此完成制冰过程，停止向制冰格输送冷气。
这里的第二时间可以根据经验值来确定，具体根据制冰机制冰量的多少，如可以设置为20-50分钟的一个具体时间。
本申请实施例的用于冰箱制冰的控制方法，通过控制制冰机工作第一时间，并获取制冰机的制冰格内的冰块温度，并判断冰块温度是否小于预设温度，在判断出冰块温度小于预设温度的情况下，控制制冰机继续工作第二时间以结束制冰过程。通过在冰块温度满足小于预设温度的结冰条件情况下，再控制制冰机继续工作第二时间，以此能保证制冰机的制冰格的所有制冰格都能完全结冰，保证了制冰质量，以此满足了用户需求，提升了用户体验。
在本申请的控制方法的另一实施例中，如图2所示，该控制方法还包括：
步骤S401、获取制冰机在制冰过程之前冰箱的门被打开的持续时间；
步骤S402、根据持续时间确定第二时间。
在一实施方式中，可由制冰过程之前所述冰箱的冷冻室或冷藏室的门被打开的持续时间来确定第二时间。
以制冰机设置于冷冻室为例，由于冷冻室的门被打开的持续时间 决定了制冰机所处的温度的高低，当门被打开的持续时间长时，制冰需要的冷量也增多，对应该第二时间加长，因而在最后控制制冰机再继续运行该第二时间，就使得制冰机的制冰时长对应了制冰需要的冷量的大小，以此完全保证了制冰格的所有冰格的制冰满足要求。
这里的持续时间是指冷冻室门打开到关闭所经过的时间，因为制冰机安装在冰箱的冷冻室内，在制冰前当冷冻室门有开启过时，其周围环境的热量会传递到冷冻室内，以此升高冷冻室内的温度，因而会影响到制冰机的制冰速度。因而在制冰前需要检测冷冻室门的门被打开的持续时间，以此确定后续的制冰的第二时间。
具体的，在一实现方式中，在获取开门时间时，可获取最近一次的门被打开的持续时间，如最近一次门被打开的持续时间为30秒，以此作为门被打开的持续时间。
或者，在另一实现方式中，上述获取门被打开的持续时间包括以下步骤：
步骤S101、记录制冰机工作前的第三时间内，冰箱的门被打开的单次时间；
步骤S102、根据单次时间确定持续时间。
即在第三时间内如1小时内记录冰箱的门被打开的单次时间，如在1小时内记录到5次开门，门被打开的持续时间由最近到最迟分别是30秒、20秒、40秒、80秒和60秒，以此根据上述记录的5次单次时间来确定门被打开的持续时间，具体确定门被打开的持续时间时，可采用求平均值方式，或者采用与计算系数相结合的计算公式进行具 体是T＝T*K1+T2*K2+T3*K3+T4*K4+T5*K5，其中T1到T5依次为最近到最迟的5次门被打开的持续时间，K1到K5为对应的计算系数，且K1≥K2≥K3≥K4≥K5，例如K1到K5依次为0.45、0.25、0.15、0.1和0.05，其计算系数之和为1。采用不同计算系数的计算方法，考虑了最近开门时间最制冰机内的温度影响最大的原则，依次使得计算出的门被打开的持续时间合理。
进一步的，基于上述的实现方式，上述获取门被打开的持续时间还包括以下步骤：
步骤S103、记录冰箱的门被打开的单次时间之间的单次间隔时间；
步骤S104、根据单次间隔时间和单次时间确定持续时间。
在上述步骤中，在除了步骤S101中记录冰箱的门被打开的单次时间还记录单次时间之间的单次间隔时间，如最近到最迟的5次开门的单次时间之间的间隔时间依次是：20秒、40秒、30秒、69秒，其中最近是指距离制冰工作最近的间隔时间，根据上述的间隔时间的不同对计算系数大小进行调整，如上述对应的计算系数K1至K5可调整为0.5、0.25、0.15、0.075和0.025，因为间隔时间越长且离制冰的时间越长，则对冷冻室的温度影响越小，因而对持续时间影响越小，以此能最终得到更准确的持续时间。
进一步的，在另一实施例中，如图3所示，上述控制方法还包括：
步骤S403、获取冰箱周围的环境温度；
步骤S404、根据环境温度和门被打开的持续时间确定第二时间。
在该实施例中，在确定第二时间时，还加入冰箱周围环境温度参数，具体可通过设置与冰箱的环境温度传感器检测环境温度，当然也可以是基于设置于其他无需通讯装置如手机、空调器上的温度传感器检测到温度后无线的发送发送至冰箱，这在目前物联网的家电设备上容易实现。由于环境温度的高低也影响到了传递到冷冻室内的外部环境热量的对应大小，在冷冻门开启时，如果外部环境温度越高，在冷冻门开启期间，其传入的热量到冷冻室则越多。因而由环境温度和门被打开的持续时间共同确定第二时间更加准确。
在控制方法的再一实施例中，在结束制冰过程后，控制方法还包括：
控制制冰格翻转以进行冰块分离。
在该实施例中，执行在上述制冰结束后，则执行离冰动作，具体是通过控制离冰电机运行带动制冰格翻转，使得冰块从冰格中脱落至储冰盒中。
本申请还提出一种用于冰箱制冰的控制装置，该冰箱内部设置有制冰机，一般设置于冰箱的冷冻室中，该制冰机包括制冰格、进水装置和储冰盒等，在该控制装置的一实施例中，如图4所示，该控制装置包括：
底部温度传感器20，用于检测制冰机的制冰格的冰块温度，该底部温度传感器设置于制冰格的底部；
控制器10，被配置成：控制制冰机工作第一时间；获取制冰机的制冰格内的冰块温度；判断冰块温度是否小于预设温度；以及在判 断出冰块温度小于预设温度的情况下，控制制冰机继续工作第二时间以结束制冰过程。
上述控制装置进一步还可包括抽水电机40，用于对制冰机的制冰格中送水；还包括冷气输送电机50用于在制冰时通过其的运行产生流通气流，并通过冷气输送通道对制冰格输送冷气，具体通过冷气输送电机50带动风扇使得冷气流输送至制冰盒中。
制冰机在制冰运行时，首先控制制冰机工作第一时间进行制冰过程，这里的控制制冰机工作具体是打开制冰机的冷气输送管路，冰箱的压缩机运行在冰箱的冷媒管路上产生冷量，通过风扇的转动在冷气输送管路形成冷气，并通过所述的冷气输送管路向制冰格输送冷气，以对制冰格中的水进行冷冻，使其逐渐转换成冰块。这里的第一时间是制冰机的基本工作时间，也即制冰机进行制冰时必须工作的基本时间，该时间有制冰机在前期研发实验过程中确定，具体根据制冰格内冰块的多少通过实验确定，如可确定为30至40分钟，以此保证制冰格能基本实现结冰。
在运行完成上述第一时间后，制冰机的控制器10再通过设置在制冰格底部的底部温度传感器20检测制冰格底部的温度，并实时判断该温度是否小于预设温度，如果小于预设温度，则认为制冰格的制冰温度满足结冰要求。
在判断输出上述冰块温度小于预设温度时，则控制制冰机再继续运行第二时间以结束制冰过程。
这里的预设温度是指判断为结冰完成的温度，根据实验确定一般 为-9℃或者-10℃。
因为在底部温度传感器20检测到的温度时制冰格底部安装传感器位置所在的区域所处的温度值，并不能完全代表整个制冰格底部的温度，制冰格中各个冰格所处的冰块温度实际是不均匀的，特别是制冰格周围的冰格冰块温度会比中间区域的高，这使得冰块温度满足了结冰要求后，底部温度传感器20所在区域的冰块结冰达到要求，但周围的冰块不一定满足要求，可能还存在结冰不完全的冰水状态，因而在冰块温度小于预设温度后，再控制制冰机运行第二时间，以使得整个制冰格的所有冰块都能完全结冰。以此完成制冰过程，停止向制冰格输送冷气。
这里的第二时间可以根据经验值来确定，具体根据制冰机制冰量的多少，如可以设置为20-50分钟的一个具体时间。
本申请实施例的用于冰箱制冰的控制装置，通过控制制冰机工作第一时间，并通过底部温度传感器20获取制冰机的制冰格内的冰块温度，并判断冰块温度是否小于预设温度，在判断出冰块温度小于预设温度的情况下，控制制冰机继续工作第二时间以结束制冰过程。通过在冰块温度满足小于预设温度的结冰条件情况下，再控制制冰机继续工作第二时间，以此能保证制冰机的制冰格的所有冰格都能完全结冰，保证了制冰质量，以此满足了用户需求，提升了用户体验。
在本申请的控制装置的另一实施例中，控制器10还被配置成：获取冰箱周围的环境温度，获取制冰机在制冰过程之前冰箱的门被打开的持续时间，根据环境温度和/或持续时间确定第二时间。
在一实施方式中，可由制冰过程之前所述冰箱的冷冻室或冷藏室的门被打开的持续时间来确定第二时间。
以制冰机设置于冷冻室为例，由于冷冻室的门被打开的持续时间决定了制冰机所处的温度的高低，当门被打开的持续时间长时，制冰需要的冷量也增多，对应该第二时间加长，因而在最后控制制冰机再继续运行该第二时间，就使得制冰机的制冰时长对应了制冰需要的冷量的大小，以此完全保证了制冰格的所有冰格的制冰满足要求。
这里的持续时间是指冷冻室门打开到关闭所经过的时间，因为制冰机安装在冰箱的冷冻室内，在制冰前当冷冻室门有开启过时，其周围环境的热量会传递到冷冻室内，以此升高冷冻室内的温度，因而会影响到制冰机的制冰速度。因而在制冰前需要检测冷冻室门的门被打开的持续时间，以此确定后续的制冰的第二时间。
具体的，在一实现方式中，在获取开门时间时，可获取最近一次的门被打开的持续时间，如最近一次门被打开的持续时间为30秒，以此作为门被打开的持续时间。
或者在另一实现方式中，确定所述冰箱的门被打开的持续时间控制器10被配置成：记录制冰机工作前的第三时间内，冰箱的门被打开的单次时间，根据单次时间确定持续时间。
即在第三时间内如1小时内记录冰箱的门被打开的单次时间，如在1小时内记录到5次开门，门被打开的持续时间由最近到最迟分别是30秒、20秒、40秒、80秒和60秒，以此根据上述记录的5次单次时间来确定门被打开的持续时间，具体确定门被打开的持续时间时， 可采用求平均值方式，或者采用与计算系数相结合的计算公式进行具体是T＝T*K1+T2*K2+T3*K3+T4*K4+T5*K5，其中T1到T5依次为最近到最迟的5次门被打开的持续时间，K1到K5为对应的计算系数，且K1≥K2≥K3≥K4≥K5，例如K1到K5依次为0.45、0.25、0.15、0.1和0.05，其计算系数之和为1。采用不同计算系数的计算方法，考虑了最近开门时间最制冰机内的温度影响最大的原则，依次使得计算出的门被打开的持续时间合理。
进一步的，基于上述的实现方式，上述获取门被打开的持续时间控制器10还被配置成：记录冰箱的门被打开的单次时间之间的单次间隔时间，根据单次间隔时间和单次时间确定持续时间。除了记录冰箱的门被打开的单次时间还记录单次时间之间的单次间隔时间，如最近到最迟的5次开门的单次时间之间的间隔时间依次是：20秒、40秒、30秒、69秒，其中最近是指距离制冰工作最近的间隔时间，根据上述的间隔时间的不同对计算系数大小进行调整，如上述对应的计算系数K1至K5可调整为0.5、0.25、0.15、0.075和0.025，因为间隔时间越长且离制冰的时间越长，则对冷冻室的温度影响越小，因而对持续时间影响越小，以此能最终得到更准确的持续时间。
在控制装置的另一实施例中，控制装置还包括环境温度传感器30，用于检测冰箱周围环境温度，控制器10还被配置成：从环境温度传感器30读取冰箱周围的环境温度；根据环境温度和门被打开的持续时间确定第二时间。
在该实施例中，在确定第二时间时，还加入冰箱周围环境温度参 数，具体可通过设置与冰箱的环境温度传感器30检测环境温度，当然也可以是基于设置于其他无需通讯装置如手机、空调器上的温度传感器检测到温度后无线的发送发送至冰箱，这在目前物联网的家电设备上容易实现。由于环境温度的高低也影响到了传递到冷冻室内的外部环境热量的对应大小，在冷冻门开启时，如果外部环境温度越高，在冷冻门开启期间，其传入的热量到冷冻室则越多。因而由环境温度和门被打开的持续时间共同确定第二时间更加准确。
在控制装置的再一实施例中，在结束制冰过程后，控制器10还被配置成：控制制冰格翻转以进行冰块分离。
