Description

设置有磁场保鲜间室的冰箱及其控制方法
本申请要求了申请日为2022年06月02日，申请号为202210625229.9，发明名称为“设置有磁场保鲜间室的冰箱及其控制方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及冷藏冷冻设备，具体提供了一种设置有磁场保鲜间室的冰箱及其控制方法。
背景技术
研究发现，磁场能够抑制微生物和霉菌的生长，延长食材的储藏周期。因此，可以使用磁场来辅助冷冻食材，进而达到延长食材储藏周期的目的。使用磁场辅助冷冻食材时，磁场在一定程度上限制了水分子的自由程，具体表现为水分子蔟中的氢键断裂。使得水在相变过程中，晶核生长受到抑制，冰晶的生长速率高于水分子的迁移速率，产生的冰晶偏小，从而对细胞造成的损伤较小，降低了食材中汁液的流失率，使食材的营养和口感能够得到更好的保存。
现有技术有些冰箱，专门设有磁场保鲜间室，一方面通过调整温度保证食品在不结冰的情况下进行保存，另一方面磁场进一步抑制细菌等微生物的繁殖和营养物质流失，为食材特别是果蔬提供更好储藏环境。磁场保鲜间室的目标设计温度一般设置为为-1.0～-3.0℃范围内，如果间室温度低于-3.0℃，则容易出现食材冻结的现象。为了使得磁场保鲜间室外观，保鲜间室门体会设计成玻璃门或者透明塑料门，保温效果差，当出风温度降低时，门壁面也随之降低到-3.0℃以下。放入的食材贴到门壁面后，就容易发生冻结现象，影响保鲜存储质量。

本实施例提供了一种设置有磁场保鲜间室的冰箱10。下面参照附图来对本发明的冰箱进行详细说明。
图1是根据本发明一个实施例的设置有磁场保鲜间室的冰箱10的储物间室示意图；图2是根据本发明一个实施例的设置有磁场保鲜间室的冰箱10的内部侧剖图。冰箱10可以包括：箱体101、门体102。箱体101内可以限定有至少一个前侧敞开的储物间室，通常为多个，如冷藏间室12、冷冻间室13、磁场保鲜间室20等等。具体的储物间室的数量和功能可以根据预先的需求进行配置。具体的储物间室的数量和功能可以根据预先的需求进行配置，在一些实施例中，冷藏间室12的保藏温度可为2～9℃，或者可为4～7℃；冷冻间室13的保藏温度可为-22～-14℃，或者可为-20～16℃。磁场保鲜间室20的设定温度可设置为-1.0～-3.0℃，以储存合适的食物，在避免储藏物冻结的情况下，减少汁液流失率，降低微生物和细菌数量，延长高质量储藏的时间。
在上述附图中示出的储物间室的位置及位置仅为示例，本领域技术人员可以根据需要进行调整。
冰箱10使用风冷制冷的方式对储物间室进行制冷。也即在箱体101内设置有制冷风道123。制冷风道123从冷冻间室13延伸至磁场保鲜间室20，在通向磁场保鲜间室20的位置处设置有保鲜风门133。制冷风道123位于冷冻间室13的部分内部布置有蒸发器141以及风机142，风机142用于促使形成流经蒸发器141并供向冷冻间室13和/或磁场保鲜间室20的制冷气流。
在冰箱10进一步设置冷藏间室12的情况下，制冷风道123还配置成从冷冻间室13延伸至冷藏间室12，并且制冷风道123通向冷藏间室12的部分设置有冷藏风门134。
风机142为制冷风道123内气流流动提供动力，能够同时向冷藏间室12、冷冻间室13、磁场保鲜间室20供风。保鲜风门133用于调整磁场保鲜间室20的制冷气流的通断，冷藏风门134用于调整冷藏间室12的制冷气流的通断。风机142、保鲜风门133、冷藏风门134均可以受控地开闭，从而使得制冷气流符合冰箱10的制冷要求。风机142对多个间室送风，利用保鲜风门133、冷藏风门134进行气流切换，减少了风路部件，节省了制冷风道123占用的空间。
冷藏间室12、冷冻间室13、磁场保鲜间室20分别具有与制冷风道123连通的送风口和回风口，制冷气流从送风口22吹入对应间室后，对间室内进行制冷后，从回风口返回制冷风道123重新与蒸发器141换热，完成制冷气流循环。冷藏间室12具有冷藏送风口122，磁场保鲜间室20具有保鲜送风口22、保鲜回风口23。
磁场保鲜间室20可以开设有环绕内部空间的气流通路，该气流通路与磁场保鲜间室20的送风口22和回风口23连通，一方面实现对磁场保鲜间室20的制冷降温，使内部温度稳定在设定保鲜温度范围内；另一方面可以使得磁场保鲜间室20各区域的温度均匀。
图3是根据本发明一个实施例的设置有磁场保鲜间室的冰箱10中磁场保鲜间室20的示意图。
磁场保鲜间室20可以设置为抽屉，例如磁场保鲜间室20可以包括桶体25、抽屉24。桶体25的后部形成与制冷风道123相连通的送风口22和回风口23。抽屉24可抽拉地设置于桶体25内，其内限定出保鲜空间，也即抽屉24内的保鲜空间可以通过磁场以及温度控制，实现磁场保鲜功能。
磁场保鲜间室20被配置为形成从送风口22依次流经桶体25的顶壁、抽屉24的前挡板、抽屉24底板的下方空间返回回风口23的环绕风道。环绕风道从磁场保鲜间室20的顶部后端的保鲜送风口22进入磁场保鲜间室20的内部，通过桶体25的顶壁后，进入抽屉24的前挡板的顶端，流经抽屉24的前挡板后从底部进入抽屉24底板的下方空间，然后返回位于桶体25后壁的保鲜回风口23，完成气流循环。也即抽屉24的前挡板内设置有风道夹层，利用风道夹层在磁场保鲜间室20前端实现送风。上述环绕风道可以使得磁场保鲜间室20内部均匀制冷，同时带走磁场组件30的热量。
磁场保鲜间室20可以使用电磁组件作为磁场元件，也可以使用永磁体作为磁场元件。例如将电磁线圈与导磁板配合形成电磁板，或者将永磁体制成的磁性板。另外，磁场组件也可以组合使用电磁线圈、永磁体配合生成磁场。
在一些实施例中，磁性组件可以包括两个相对设置的磁性板，例如布置在磁场保鲜间室20的顶壁和底壁，磁性板的磁场方向可以设置为朝向相同，从而在磁场保鲜空间内形成均匀的具有满足保鲜要求强度的均匀的磁场。
在一些实施例中，磁场组件还可以包括导磁带。导磁带用于连接相对设置的磁性板，从而以形成抽屉24的环形导磁通路。环形导磁通路可以由具有低矫顽力和高磁导率的材料制成，其形成的导磁通路可以用于聚拢磁场，提高储物空间内磁场的均匀性，同时可以减少磁场向外部释放，减少对磁场保鲜间室20外侧的其他部件造成干扰(例如避免磁化其他部件等)。
图4是根据本发明一个实施例的设置有磁场保鲜间室的冰箱10的控制组件的系统框图。控制器17包括存储器172和处理器171，其中存储器172存储有机器可执行程序173，机器可执行程序173被处理器171执行时实现本实施例的设置有磁场保鲜间室的冰箱的控制方法。
控制器17与制冷系统、风机142、保鲜风门133、冷藏风门134信号连接，用于提供控制信号，控制信号用于控制风机142、保鲜风门133、冷藏风门134的开闭，从而调整制冷。控制器17可以集成于冰箱10的主控板上。
控制器17可以由各种具有一定数据处理能力的器件实现，在一个典型的配置中，控制器17 还可以包括输入/输出接口，从而获取储藏间室温度等外部检测信号，以作为控制依据。各储物间室内部分别布置有温度传感器等温度检测部件，从而获取储物间室的内部温度。控制器17与这些温度检测部件信号连接，从而获取所需的温度参数。
需要说明的是，在以下介绍本实施例的设置有磁场保鲜间室的冰箱的控制方法的流程图中表示或在此以其他方式描述的逻辑和/或步骤，例如，可以被认为是用于实现逻辑功能的可执行指令的定序列表，可以具体实现在任何计算机可读介质中，以供指令执行系统、装置或设备(如基于计算机的系统、包括处理器的系统或其他可以从指令执行系统、装置或设备取指令并执行指令的系统)使用，或结合这些指令执行系统、装置或设备而使用。
存储器172的更具体的示例包括以下：具有一个或多个布线的电连接部(电子装置)，便携式计算机盘盒(磁装置)，随机存取存储器(RAM)，只读存储器(ROM)，可擦除可编辑只读存储器(EPROM或闪速存储器)，光纤装置，以及便携式光盘只读存储器(CDROM)。
应当理解，本发明的各部分可以用硬件、软件、固件或它们的组合来实现。在上述实施方式中，多个步骤或方法可以用存储在存储器172中且由合适的指令执行系统执行的软件或固件来实现。
此外，需要指出的是，在本发明的装置和方法中，显然，各部件或各步骤是可以分解和/或重新组合的。这些分解和/或重新组合应视为本发明的等效方案。并且，执行上述系列处理的步骤可以自然地按照说明的顺序按时间顺序执行，但是并不需要一定按照时间顺序执行，某些步骤可以并行或彼此独立地执行。对本领域的普通技术人员而言，能够理解本发明的方法和装置的全部或者任何步骤或者部件，可以在任何计算装置(包括处理器、存储介质等)或者计算装置的网络中，以硬件、固件、软件或者它们的组合加以实现，这是本领域普通技术人员在阅读了本发明的说明的情况下运用他们的基本编程技能就能实现的。
本实施例还提供了一种设置有磁场保鲜间室的冰箱10的控制方法，图5是根据本发明一个实施例的设置有磁场保鲜间室的冰箱的控制方法的示意图。该设置有磁场保鲜间室的冰箱的控制方法一般性地可以包括：
步骤S502，在冰箱启动制冷之后，获取磁场保鲜间室的温度。
步骤S504，根据磁场保鲜间室的温度控制保鲜风门的开闭。
步骤S506，在保鲜风门处于打开状态下，获取蒸发器的温度。蒸发器的温度可以由设置于蒸发器处的温度检测装置测量得到。
步骤S508，根据蒸发器的温度控制风机的运行模式。该步骤可以包括判断蒸发器的温度是否大于等于预设的第一温度阈值；若是，控制风机持续开启；判断蒸发器的温度是否小于预设的第一温度阈值并且大于等于预设的第二温度阈值；若是，控制风机间隔开启。第一温度阈值以及第二温度阈值可以根据蒸发器正常工作的温度状态以及磁场保鲜装置的存储要求进行设置，并且第一温度阈值设置为大于第二温度阈值，例如第一温度阈值可以设置为-15摄氏度，第二温度阈值可以设置为-20摄氏度。
在风机间隔开启的情况下，风机的启停比随蒸发器的温度的下降而相应降低。可替代地，风机的启停比也可以设置为固定值，例如开启1分钟、关闭1分钟。
在蒸发器的温度小于第二温度阈值的情况下，关闭保鲜风门，并控制风机持续开启。
上述风机的工作原理为：如果蒸发器温度过低，此时送入磁场保鲜间室的制冷气流温度过低，有可能引起磁场保鲜间室内部的储藏物冻结，因此风机在蒸发器温度下降至一定温度区间的情况下，通过间隔启动来避免送入磁场保鲜间室的制冷气流温度过低。如果蒸发器的温度继续降低，则通过关闭保鲜风门的方式防止磁场保鲜间室内部出现冻结。上述风机的控制方式还可以尽量避免对冷藏间室、冷冻间室的制冷产生影响。
对于冷藏间室的控制，在冰箱启动制冷之后还可以获取冷藏间室的温度；根据冷藏间室的温度控制冷藏风门的开闭。
上述根据磁场保鲜间室的温度控制保鲜风门的开闭的步骤包括：在磁场保鲜间室的温度大于等于预设的保鲜制冷开机温度的情况下，控制保鲜风门打开；并且在磁场保鲜间室的温度小于等于预设的保鲜制冷关机温度的情况下，控制保鲜风门关闭。
上述根据冷藏间室的温度控制冷藏风门的开闭的步骤包括：在冷藏间室的温度大于等于预设的冷藏制冷开机温度的情况下，控制冷藏风门打开；并且在冷藏间室的温度小于等于预设的冷藏制冷关机温度的情况下，控制冷藏风门关闭。
通过上述控制方式，可以保证磁场保鲜间室以及冷藏间室的温度始终处于各自的规定范围内，满足了储物温度的要求。
进一步地，在保鲜风门以及冷藏风门均处于开启的状态下，获取磁场保鲜间室的降温速度以及冷藏间室的降温速度；在磁场保鲜间室的降温速度超过冷藏间室的降温速度的比例超过设定阈值时，控制保鲜风门间隔开启。保鲜风门的启停比随磁场保鲜间室的降温速度超过冷藏间室的降温速度的比例的增加而相应减小。
另一种可选的调整方案为：保鲜风门开度可调，并且在保鲜风门以及冷藏风门均处于开启的状态下，获取磁场保鲜间室的降温速度以及冷藏间室的降温速度；在磁场保鲜间室的降温速度超过冷藏间室的降温速度的比例超过设定阈值时，减小保鲜风门的开度，并且保鲜风门的开度随磁场保鲜间室的降温速度超过冷藏间室的降温速度的比例的增加而相应减小。
上述控制方式的工作原理为：尽量保证磁场保鲜间室和冷藏间室同时出风制冷，在冷藏间室进行制冷的情况下，蒸发器受冷藏回风影响，其温度相对较高，这也使得磁场保鲜间室的制冷气流温度相应提高，而冷藏风门关闭时，冷藏间室停止气流循环，蒸发器温度相应降低，此时磁场保鲜间室的温度也会相应降低。因此为了避免磁场保险间室内部储藏物被冻结，可以通过调整冷藏风门和保鲜风门来保证磁场保鲜间室和冷藏间室同时出风制冷。对于应用本实施例方案的冰箱进行测试在冷藏间室进行制冷的情况下，蒸发器大约为-15℃左右；而冷藏风门关闭时，冷藏间室停止气流循环，蒸发器温度可以从-15℃下降到-20℃以下，此时靠近磁场保鲜间室避免的储藏物极可能被冻结。
图6是根据本发明一个实施例的设置有磁场保鲜间室的冰箱的控制方法中调节保鲜风门和冷藏风门的流程流程图。调节上述风门的流程包括：
步骤S602，冰箱压缩机启动，风机启动；
步骤S604，获取磁场保鲜间室的温度T-c以及冷藏间室的温度T-r；
步骤S606，判断T-r是否大于等于冷藏制冷开机温度T-ron，也即T-r≥T-ron是否成立；
步骤S608，开启冷藏风门；
步骤S610，判断T-c是否大于等于保鲜制冷开机温度T-con，也即T-c≥T-con是否成立；
步骤S612，开启保鲜风门；
步骤S614，判断T-r是否小于冷藏制冷关机温度T-roff，也即T-r≤T-roff是否成立；
步骤S616，关闭冷藏风门；
步骤S618，判断T-c是否小于等于保鲜制冷关机温度T-coff，也即T-c≤T-coff是否成立；
步骤S620，关闭保鲜风门。
步骤S622，执行冷冻间室的制冷温度控制。
图7是根据本发明一个实施例的设置有磁场保鲜间室的冰箱的控制方法中调节风机的流程流程图。该调节风机的流程包括：
步骤S702，保鲜风门打开，磁场保鲜间室开启送风制冷；
步骤S704，获取蒸发器的温度T-def；
步骤S706，判断T-def是否大于等于第一温度阈值T-d1，也即T-def≥T-d1是否成立；
步骤S708，控制风机持续开启；
步骤S710，判断T-def是否小于第一温度阈值T-d1并且大于等于预设的第二温度阈值T-d2， 也即T-d1>T-def≥T-d2是否成立；
步骤S712，控制风机间隔开启；
步骤S714，判断T-def是否小于第二温度阈值T-d2，也即T-d2>T-def是否成立；
步骤S716，关闭保鲜风门，并切换至对冷藏间室和/或冷冻间室制冷。
第一温度阈值T-d1以及第二温度阈值T-d2可以根据蒸发器正常工作的温度状态以及磁场保鲜装置的存储要求进行设置，在一种具体实施例中，例如T-d1可以设置为-15摄氏度，T-d2可以设置为-20摄氏度。风机间隔开启可以设置为开启1分钟、关闭1分钟。
调节风机的流程可以有效防止磁场保鲜间室制冷气流送风温度过低，从而可以避免储藏物被冻结，从而提高了保鲜存储质量。
至此，已经结合前文的多个实施例描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围并不仅限于这些具体实施例。在不偏离本发明技术原理的前提下，本领域技术人员可以对上述各个实施例中的技术方案进行拆分和组合，也可以对相关技术特征作出等同的更改或替换，凡在本发明的技术构思和/或技术原理之内所做的任何更改、等同替换、改进等都将落入本发明的保护范围之内。
