具体实施方式
图1是根据本发明一个实施例的冰箱的示意性剖视图，其中示出了为储物区和解冻区制冷的冷气流流动路径。参见图1，冰箱100可包括箱体110、解冻室120、制冷系统、微风道转盘180以及控制模块。
箱体110可限定有储物间室，储物间室可包括一个或多个储物区112和一个解冻区111。解冻室120可设置在解冻区111内。在一些实施例中，储物间室可包括多个，在图示实施例中，箱体110限定有两个储物间室。储物间室均为向前开口。在另一些实施例中，储物间室也可为向上开口。
在箱体110限定有两个储物间室情况下，储物间室可包括冷藏间室和冷冻间室。本领域技术人员均熟知地，冷藏间室是指对食材的保藏温度为0～+8℃的储物间室；冷冻间室是指对食材的保藏温度为-24～-14℃的储物间室。解冻室120可设置于冷藏间室内，以降低解冻或维持软冷冻温度对储物间室内保藏食材的影响。
制冷系统可设置为产生冷气流。具体地，制冷系统可包括压缩机、冷凝器、节流元件和蒸发器。
微风道转盘180可设置为使冷气流有选择地进入储物区112和解冻室120。冷气流可与储物区112或解冻室120内的空气换热，以使储物区112或解冻室120的温度降低，从而满足储物间室和解冻室120的制冷需求。
进一步地，冰箱100还可包括隔热板130，设置在储物间室内，配置成将储物间室分隔出储物区112和解冻区111。解冻室120设置于解冻区111。在图示实施例中，隔热板130均设置为水平方向延伸。本发明实施例通过设置隔热板130，可将解冻室120所在的储物间室分隔出一个解冻区111和至少一个储物区112，进而将解冻室120设置于解冻区111，可有效隔绝解冻室120与储物区112的热交换，减少解冻室120受储物区112制冷影响。解 冻区111可设置于储物区112的下方。
在另一些实施例中，冰箱100还可设置有竖直方向延伸的隔热板，水平方向延伸的隔热板和竖直方向延伸的隔热板可首尾相接围设于解冻室120外侧。由此，可进一步隔绝解冻室120与储物区112的热交换，从而保证解冻室120的保温性能。
控制模块可包括存储器以及处理器。存储器内可存储有控制程序，控制程序被处理器执行时用于实现根据本发明任一个实施例的冰箱温度控制方法。控制模块可设置在冰箱的电控板上，以便于控制模块的安装与维修。
在一些实施例中，冰箱100可包括第一温度传感器和第二温度传感器。第一温度传感器可设置在储物区112内，用于检测该储物区112的温度。第二温度传感器可设置在解冻室120内，用于检测解冻室120的温度。通过第一温度传感器和第二温度传感器可分别检测储物区和解冻室的温度，方便控制储物区112和解冻室120的温度。
在一些实施例中，冰箱100还可包括加热单元。加热单元可设置为对解冻室120进行解冻。具体地，加热单元可包括至少一部分设置于解冻室120或通达至解冻室120内的电磁波发生系统。电磁波发生系统可用于产生电磁波来解冻待处理物。电磁波发生系统可至少部分设置于箱体110的外侧，以避免产生的热量造成间室温度波动。这里的箱体110的外侧是指箱体110暴露于环境空气的一侧，箱体110的内侧即为储物间室。
电磁波发生系统可包括：电磁波发生模块，用于产生电磁波信号；供电模块，与电磁波发生模块电连接，用于为电磁波发生模块提供电能，使得电磁波发生模块产生电磁波信号；辐射天线，与电磁波发生模块电连接，用于根据电磁波信号辐射相应频率的电磁波，对解冻室120内的待处理物进行解冻；信号处理及测控电路，用于对电磁波的特征参数进行检测。
电磁波发生模块和供电模块可设置于箱体110的外侧。信号处理及测控电路可设置于解冻室120的底部。信号处理及测控电路可集成于一块电路板，以便于信号处理及测控电路的安装及维修。
在一些实施例中，冰箱100可为风冷冰箱。每个储物间室内可分别设置有一个风道盖板140，以在每个储物间室内分隔出制冷风道150。每个制冷风道150可分别设置有一个蒸发器160和一个制冷风扇170，以使制冷系统可单独为其中一个储物间室制冷。当然，在箱体限定有多个储物间室的情况 下，还可仅在其中一个制冷风道150内设置一个蒸发器160和一个制冷风扇170，并且蒸发器160所在的制冷风道150可选择地与其它制冷风道150连通。在该实施例中，通过蒸发器160所在的制冷风道150可选择地与其它制冷风道150连通，可使制冷系统可仅为蒸发器160所在的储物间室制冷或同时为多个储物间室制冷。
其中，风道盖板140可开设有至少一个送风口141和一个回风口142，以循环储物间室内的空气进行制冷。送风口141的数量可为多个。解冻室120可开设一个送风口141和一个回风口142，以循环解冻室120内的空气进行制冷。回风口142可设置于多个送风口141的下方，以使制冷更加充分。
在另一些实施例中，冰箱100还可为直冷冰箱，即每个储物间室可均设置有一个蒸发器160，并通过自然对流进行传冷。
图2是根据本发明一个实施例的风道盖板140的示意性剖视图。参见图2，在一些实施例中，风道盖板140可与储物间室的后壁夹置形成制冷风道150的回风部，蒸发器160可设置于回风部。风道盖板140本身可形成有间室风道的至少一个送风部，每个送风部均可开设有至少一个送风口141和一个进风口143。
微风道转盘180可设置成可容置制冷风扇170的蜗壳。蜗壳设置为可旋转并将其出风口与一个送风部的进风口143对接，以将由蒸发器160制冷后的冷气流输送至一个送风部并由该送风部的送风口141吹出。
图3是根据本发明一个实施例的冰箱温度控制方法示意图。参见图3，在该实施例中，冰箱温度控制方法可以包括步骤S302至步骤S308。
步骤S302，在储物区的温度大于等于预设储物开机温度阈值时，控制制冷系统启动；其中，制冷系统启动后可产生冷气流；
步骤S304，获取解冻室的温度，并且将解冻室的温度与预设解冻关机温度阈值进行对比；
步骤S306，若解冻室的温度大于等于预设解冻关机温度阈值，则控制微风道转盘将冷气流同时导向储物区和解冻室；
步骤S308，若解冻室的温度低于预设解冻关机温度阈值，则控制微风道转盘将冷气流全部导向储物区，以单独对储物区进行制冷。
本发明实施例通过在储物区的温度大于等于储物开机温度阈值时启动制冷系统来产生冷气流，通过解冻室的温度和预设解冻关机温度阈值的对比 来确定冷气流导向方向，并通过微风道转盘来完成冷气流的定向导向，从而满足储物区和解冻室的不同制冷需求，并且在对间室温度控制过程中，无需频繁切换电磁阀，有效延长了电磁阀的使用寿命。
考虑到对储物区112或解冻室120制冷时，储物区的温度或解冻室120的温度会下降。对于步骤S306，在一些实施例中，在控制微风道转盘180将冷气流同时导向储物区112和解冻室120之后，还可以在储物区112的温度下降至预设储物关机温度阈值，并且解冻室120的温度仍高于预设解冻关机温度阈值时，控制微风道转盘180将冷气流全部导向解冻室120，以单独对解冻室120制冷，这时解冻室120的温度会迅速下降，使得置于解冻室120的食材快速穿过冰晶带，便于食材保鲜。
在一些进一步地实施例中，在控制微风道转盘180将冷气流全部导向解冻室120之后，还可以在解冻室120的温度下降至预设解冻关机温度阈值时，停止对解冻室120进行制冷。由于储物区112的温度先下降至预设储物关机温度阈值，因而首先会停止对储物区112制冷，之后，在解冻室120的温度下降至预设解冻关机温度阈值时，停止对解冻室120制冷，以使储物区112和解冻室120均能满足各自的制冷需求，进而保证了储物区和解冻室120都能维持正常的温度控制。
对于步骤S306，在另一些实施例中，在控制微风道转盘180将冷气流同时导向储物区112和解冻室120之后，还可以在解冻室120的温度下降至预设解冻关机温度阈值，并且储物区112的温度仍高于预设储物关机温度阈值时，控制微风道转盘180将冷气流全部导向储物区112，以单独对储物区112制冷。
在一些进一步地实施例中，在控制微风道转盘180将冷气流全部导向储物区112之后，还可以在储物区112的温度下降至预设储物区关机温度阈值时，停止对储物区112制冷。由于解冻室120的温度先下降至预设解冻关机温度阈值，因而会首先停止对解冻室120制冷，之后，在储物区112的温度下降至预设储物关机温度阈值时，停止对储物区112制冷，以使储物区和解冻室120均能满足各自的制冷需求，进而保证了储物区112和解冻室120都能维持正常的温度控制。
为了方便对冷冻食材的解冻，在一些实施例中，冰箱100还可以包括加热单元。加热单元可设置为对解冻室120进行解冻。图4是根据本发明另一 个实施例的冰箱温度控制方法流程图。参见图4，在该实施例中，冰箱温度控制方法还可以包括步骤S402至步骤S408。
步骤S402，在停止对解冻室120制冷时，检测解冻室120的待处理物放入事件。待处理物一般指需要放入冰箱进行冷冻、解冻、或冷藏的食材/食物。
步骤S404，当检测到解冻室120放入了待处理物时，获取待处理物的属性信息。属性信息可包括待处理物种类、待处理物外形尺寸、和/或待处理物温度。待处理物温度包括待处理物的表面温度和/或中心温度。
步骤S406，根据属性信息确定加热单元的运行参数。运行参数包括但不限于加热单元的开启时间、关闭时间、功率。
步骤S408，按照运行参数控制加热单元运行。
在该实施例中，当解冻室120放入了待处理物时，可以获取待处理物的属性信息，进而根据属性信息可以确定出加热单元的运行参数，并以此运行参数控制加热单元运行，由此能够获得较佳的解冻效果，减少因解冻导致食物品质下降的问题。
在一些实施例中，在属性信息包括待处理物温度时，步骤S406可以包括：计算待处理物温度与解冻室关机温度阈值的温度差；根据温度差确定出加热单元的开启时间。该实施例通过待处理物温度与解冻室关机温度阈值的温度差确定加热单元的开启时间，使得解冻时间更加合理，减少了过度解冻导致食物品质下降的问题。
第一预设温度阈值、第二预设温度阈值可根据对解冻室120进行解冻的实验确定，第二预设温度阈值可设置为0℃，以使解冻室120在解冻时处于负温解冻状态。当然，第一预设温度阈值、第二预设温度阈值还可分别设置为一定的阈值范围。
图5是根据本发明一个实施例的冰箱温度控制方法流程图。参见图5，在该实施例中，冰箱温度控制方法可包括步骤S502至步骤S524。

步骤S506，开启冰箱的制冷系统，以产生冷气流；
步骤S508，获取解冻室的温度；
步骤S510，判断解冻室的温度是否≥预设解冻关机温度阈值；若是，则执行步骤S512；若否，则执行步骤S522；
步骤S512，控制微风道转盘将冷气流同时导向冷藏间室和解冻室；
步骤S514，判断储物区的温度是否下降至预设储物关机温度阈值；若是，则执行步骤S516；若否，则执行步骤S520；
步骤S516，判断解冻室的温度是否下降至预设解冻关机温度阈值；若是，执行步骤S518；若否，则执行步骤S520；
步骤S518，关闭冰箱的制冷系统；
步骤S520，控制微风道转盘将冷气流全部导向解冻室；
步骤S522，控制微风道转盘将冷气流全部导向储物区。
图6是根据本发明另一个实施例的冰箱温度控制方法流程图。参见图6，在该实施例中，冰箱温度控制方法可包括步骤S602至步骤S626。
步骤S602，获取储物区的温度。
步骤S604，判断储物区的温度是否≥预设储物开机温度阈值；若是，则执行步骤S606；若否，则继续执行步骤S602。
步骤S606，开启冰箱的制冷系统，以产生冷气流。
步骤S608，获取解冻室的温度。
步骤S610，判断解冻室的温度是否≥预设解冻关机温度阈值；若是，则执行步骤S612；若否，则执行步骤S626。
步骤S612，控制微风道转盘将冷气流同时导向储物区和解冻室。
步骤S614，获取储物区的温度。

步骤S720，关闭冰箱的制冷系统。
本实施例中，由于解冻室120的温度先下降至预设解冻关机温度阈值，因而会首先停止对解冻室120制冷，将冷气流全部导向储物区112，之后，在储物区112的温度下降至预设储物关机温度阈值时，关闭制冷系统从而停止对储物区112制冷，以使储物区112和解冻室120均能满足各自的制冷需求，进而保证了储物区112和解冻室120都能维持正常的温度控制。需要说明的是，本发明的实施例的一或多个示例在附图中示出。每个示例是通过解释本发明的方式提供的，并不是对本发明的限制。实际上，对于本领域技术人员来说显而易见的是，在不脱离本发明的范围或精神的情况下，可以对本发明进行各种修改和变型。例如，作为一个实施例的一部分示出或描述的特征可以与另一个实施例一起使用，以产生又一个实施例。
本发明实施例提供了一种冰箱温度控制方法及冰箱，在发明提供的冰箱 温度控制方法中，通过在储物区的温度大于等于预设储物开机温度阈值时启动制冷系统来产生冷气流，并通过解冻室120的温度和预设解冻关机温度阈值的对比来确定冷气流导向方向，并通过利用微风道转盘来完成冷气流的定向导向，从而满足储物区112和解冻室120的不同制冷需求，在制冷过程中不仅可以减少电磁阀的使用，而且能够有效减少电磁阀的切换次数，延长电磁阀的使用寿命。
进一步地，本发明实施例还可以通过待处理物温度与预设解冻关机温度阈值的温度差确定加热单元的开启时间，进而合理控制解冻时间，避免过度解冻导致食物品质下降。
进一步地，本发明实施例的冰箱中还设置隔热板130，可将解冻室120所在的储物间室分隔出解冻区111和储物区112，进而将解冻室120设置于解冻区，可有效隔绝解冻室120与储物区112的热交换，从而减少了解冻室120受储物区112制冷影响。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
