根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
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冷冻保鲜区制冷的冷气流流动路径；

图4是根据本发明一个实施例的冰箱保鲜控制方法流程图。
具体实施方式
图1是根据本发明一个实施例的冰箱100的示意性剖视图，其中示出了为储物区和冷冻保鲜区制冷的冷气流流动路径。参见图1，冰箱100可包括箱体110、冷冻保鲜室120、以及控制模块。
箱体110可限定有至少一个储物间室。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。
冷冻保鲜室120可设置在至少一个储物间室内。在箱体110限定有两个储物间室情况下，至少一个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。冷冻保鲜室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。
进一步地，冰箱100还可包括至少一个隔热板130，与冷冻保鲜室120共同设置在一个储物间室内，并将该储物间室分隔出冷冻保鲜区111。冷冻保鲜室120设置于冷冻保鲜区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，可将冷冻保鲜室120所在的储物间室分隔出一个冷冻保鲜区111和至少一个储物区112，进而将冷冻保鲜室120设置于冷冻保鲜区111，可有效隔绝冷冻保鲜室120与储物间室内其他储物区112的热交换，减少冷冻保鲜室120受其它储物区112制冷影响。冷冻保鲜区111可设置于至少一个储物区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冷冻保鲜室120外侧。由此，可进一步隔绝冷冻保鲜室120与储物间室内其他储物区112的热交换，从而保证冷冻保鲜室的保温性能。
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保鲜控制方法。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可包括温度传感器。温度传感器可设置于冷冻保鲜室120的内壁，用于感测冷冻保鲜室120内是否放置有待处理物，并在感测到待处理物时，检测待处理物温度。通过将温度传感器设置于冷冻保鲜室120的内壁，有助于提高待处理物温度检测精确性。
在一些实施例中，冰箱100还可包括制热单元和制冷单元。制冷单元可设置为对冷冻保鲜室120进行制冷，以使置于冷冻保鲜室120的待处理物冷冻。具体地，制冷单元可包括压缩机、冷凝器、节流元件和蒸发器。制热单元可设置为对冷冻保鲜室120进行制热，以使冷冻的待处理物解冻。具体地，制热单元可包括至少一部分设置于冷冻保鲜室120或通达至冷冻保鲜室120内的电磁波发生系统，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，对冷冻保鲜室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冷冻保鲜室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，以使制冷单元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，可使制冷单元可仅为蒸发器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。冷冻保鲜室120可开设一个送风口141和一个回风口142，以循环冷冻保鲜室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。
风道盖板140还可设置有容置制冷风扇170的蜗壳180。蜗壳180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保鲜控制方法示意图。参见图3本 实施例提供的冰箱保鲜控制方法可包括步骤S302至步骤S308。其中，冰箱100可包括箱体110、冷冻保鲜室120、以及控制模块。箱体110可限定有至少一个储物间室。冷冻保鲜室120可设置于至少一个储物间室内。控制模块可包括存储器以及处理器，存储器内存储有控制程序，控制程序被处理器执行时用于实现本发明中任一实施例的冰箱保鲜控制方法。
步骤S302，检测冷冻保鲜室内是否放置有待处理物；待处理物指放置于冰箱中需要保鲜的食材。
步骤S304，若是，获取待处理物温度。待处理物温度可以为待处理物的表面温度。
步骤S306，获取预设的待处理物温度与冰箱的运行模式的对应关系；
步骤S308，控制冰箱100按照获取到的待处理物温度对应的运行模式运行。
本发明实施例通过检测置于冷冻保鲜室内的待处理物温度，进而根据待处理物温度的不同，控制冰箱100按照不同的运行模式运行，从而实现冰箱100中食材的即食保鲜。
在一些实施例中，冰箱100还可以包括设置于冷冻保鲜室120的内壁的温度传感器。该实施例中，步骤S302可包括通过温度传感器感测冷冻保鲜室内是否放置有待处理物，并在感测到待处理物时，检测待处理物温度。
运行模式可包括快速冷冻模式、快速解冻模式。快速冷冻模式可配置成对冷冻保鲜室120制冷，以使待处理物温度降低。快速解冻模式可配置成对冷冻保鲜室120解冻，以使待处理物温度上升。运行模式还可包括保鲜模式。保鲜模式可配置成使冷冻保鲜室120的温度维持在预设保鲜温度阈值。
冰箱100运行快速冷冻模式时，可通过旋转蜗壳使制冷单元单独对冷冻保鲜室120进行制冷，此时，进入冷冻保鲜室120内的风量增加，可使置于冷冻保鲜室120内的食材内部迅速穿过冰晶带，有助于提升保鲜效果。
冰箱100运行快速解冻模式时，可通过制热单元对冷冻保鲜室120进行制热，以使冷冻保鲜室120温度上升，从而可使置于冷冻保鲜室120内的食材温度上升，实现冷冻食材的解冻。
在执行步骤S306之前，在一些实施例中，可预先建立待处理物温度与运行模式的对应关系，并可存储于控制模块，进而在控制模块获取到当前待处理物温度后，可根据预先建立的待处理物温度与运行模式的对应关系确定 出当前待处理物温度对应的运行模式并控制冰箱100按照该确定出的运行模式运行。该实施例的冰箱100能够根据待处理物温度不同，自动进入不同的运行模式，使得食材的保鲜控制方法更加灵活，保鲜效果更好。
在一些实施例中，步骤S308可包括：在待处理物温度大于第一预设温度阈值时，控制冰箱100按照快速冷冻模式运行；在待处理物温度小于第二预设温度阈值时，控制冰箱100按照快速解冻模式运行。第一预设温度阈值可设置为大于第二预设温度阈值。
在另一些实施例中，运行模式还可包括保鲜模式。其中保鲜模式配置成使冷冻保鲜室的温度维持在预设保鲜温度阈值。预设保鲜温度阈值可设置为在第一预设温度阈值与第二预设温度阈值之间。此时，控制冰箱100按照待处理物温度对应的运行模式运行的步骤还可包括：在待处理物温度大于等于第二预设温度阈值并且小于等于第一预设温度阈值时，控制冰箱100按照保鲜模式运行。
需要说明的是，第一预设温度阈值、第二预设温度阈值、以及预设保鲜温度阈值可通过食材在不同温度下的保鲜效果进行实验确定。
示意性的，第一预设温度阈值可以设置为0℃，第二预设温度阈值可设置为-5℃，则预设保鲜温度阈值设置为-4℃。需要说明的是，尽管示意性实施例中设定的第一预设温度阈值、第二预设温度阈值、预设保鲜温度阈值为点值，但本发明中的第一预设温度阈值、第二预设温度阈值、预设保鲜温度阈值均不局限于点值，在一些实施例中，第一预设温度阈值、第二预设温度阈值、预设保鲜温度阈值也可分别设定为不同阈值范围。
考虑到食材的冷冻都是由间室的冷风与食材外表面换热，然后从外到内慢慢导热冷冻，对于种类不同的食材，或外形尺寸差异比较大的食材，在相同时间范围内实现食材内外全部冷冻时所需的冷冻温度不同，为避免过度冷冻，可设置一个安全温度，从而保证食材内外都已经快速穿过冰晶带，确保保鲜效果。针对这一情况，在一些实施例中，在冰箱100按照快速冷冻模式运行过程中，若待处理物温度降低至预设安全温度阈值，则可控制冰箱100按照快速解冻模式运行，以使冷冻保鲜室120快速升温，进而对待处理物进行快速解冻。此时，若待处理物温度上升至预设保鲜温度阈值时，则控制冰箱100按照保鲜模式运行。
预设安全温度阈值可设置为小于第二预设温度阈值。预设安全温度阈值 可通过食材在不同温度下的保鲜效果进行实验确定。在一些进一步实施例中，预设安全温度阈值可设置为小于-5℃并且大于等于-14℃。
示意性的，在第二预设温度阈值设置为-5℃的情况下，预设安全温度阈值可设置为-10℃。本发明通过设定预设安全温度阈值小于第二预设温度阈值，可最大程度保证食材内外均可快速穿过冰晶带，从而获得更好地保鲜效果。
考虑到当前放置到冷冻保鲜室120内的待处理温度有高有底，为了获得较佳的保鲜效果，可根据放置到冷冻保鲜室内的食材温度的不同来灵活调整控制方式。例如，在当前放置到冷冻保鲜室120的待处理温度偏低时，首先可将待处理温度和第二预设温度阈值进行对比，若待处理温度低于第二预设温度阈值，则可控制冰箱100按照快速解冻模式运行，若待处理温度大于等于第二预设温度阈值，则可进一步判断待处理温度是否也小于等于第一预设温度阈值，若是，则控制冰箱100按照保鲜模式运行，若否，则控制冰箱100按照快速冷冻模式运行。再例如，如果用户放置到冷冻保鲜室120内的食材温度本身已在软冷冻温度，则可控制冰箱100按照保鲜模式运行。
在一些实施例中，在冰箱100按照快速解冻模式运行过程中，若待处理物温度上升到预设保鲜温度阈值，则控制冰箱100按照保鲜模式运行，以使冷冻保鲜间室120内的温度保持在预设保鲜温度阈值，进而对待处理物进行软冷冻保存。
下面以第一预设温度阈值可以设置为0℃，第二预设温度阈值可设置为-5℃，预设保鲜温度阈值设置为-4℃，预设安全温度阈值可设置为-10℃为例进行说明。
在冷冻保鲜室120放置有待处理物时，可通过设置冷冻保鲜室120的内壁的温度传感器检测当前置于冷冻保鲜室120的待处理物温度，记作T，接下来可将T分别与0℃、-5℃、-4℃进行比较，可得到T＞0℃，-5℃≤T≤0℃，以及T＜-5℃的比较结果。
若T＞0℃，则控制冰箱100按照快速冷冻模式运行，以使T快速降低至-10℃，然后，控制冰箱100按照快速解冻模式运行，以使已经降低至-10℃的T再快速上升至-4℃，之后，控制冰箱100按照保鲜模式运行，以使上升至-4℃的T保持在-4℃。
若-5℃≤T≤0℃，则可控制冰箱按照保鲜模式运行，以使T保持在-4℃。
若T＜-5℃，则可控制冰箱按照快速解冻模式运行，以使T快速上升至-4℃，之后，控制冰箱100按照保鲜模式运行，以使上升至-4℃的T保持在-4℃。
图4是根据本发明另一个实施例的冰箱保鲜控制方法流程图。参见图4，该实施例提供的冰箱保鲜控制方法可包括步骤S402至步骤S416。

进一步地，本发明通过设定预设安全温度阈值小于第二预设温度阈值，可最大程度保证食材内外均可快速穿过冰晶带，从而获得更好地保鲜效果。
进一步地，本发明通过设置至少一个隔热板130，可将冷冻保鲜室所在的储物间室分隔出冷冻保鲜区111和至少一个储物区112，进而将冷冻保鲜室120设置于冷冻保鲜区111，可有效隔绝冷冻保鲜室120与储物间室内其他储物区112的热交换，减少冷冻保鲜室120受其它空间制冷影响。
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。
