导磁组件230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，减少磁场向外部释放，减少对储物组件210外侧的其他部件造成干扰(例如避免磁化其他部件等)。导磁组件230可以使用硅钢片或类似材料制成。
第一导磁件231以及第二导磁件232可以分别包括导磁板。也即第一导磁件231以及第二导磁件232可以分别为导磁板的板状结构。导磁板分别与永磁板对应设置，并且导磁连接件233从导磁板的边缘沿储物组件210的外侧延伸并连接至另一侧的导磁板。例如第一导磁件231的导磁板贴靠第一磁体部件221的永磁板，第二导磁件232的导磁板贴靠第二磁体部件222的永 磁板。导磁组件230可以一体件，也即第一导磁件231、第二导磁件232、以及导磁连接件233一体成形。在另一些实施例中第一导磁件231、第二导磁件232、以及导磁连接件233也可以通过焊接、粘接进行固定。

储物空间在导磁板所在平面上的投影位于导磁板的范围内，永磁板的尺寸小于或等于其相对的导磁板。也就是说导磁板可以等于或略大于储物组件210的相应侧面。在第一磁体部件221设置于储物组件210的顶壁，第二磁体部件222设置于储物组件210的底壁的实施例中，第一导磁件231的导磁板覆盖储物空间的顶面，而第二导磁件232的导磁板覆盖储物空间的底面。

导磁连接件233用于连接第一导磁件231的导磁板以及第二导磁件232的导磁板，导磁连接件233的尺寸大小可以根据对磁场的状态进行设置。导磁连接件233可以为长条状，分别连接至导磁板一侧的中部。
导磁连接件233可以包括：第一连接段235、第二连接段236。其中第一连接段235连接第一导磁件231的导磁板以及第二导磁件232的导磁板的一侧，而第二连接段236连接第一导磁件231的导磁板以及第二导磁件232的导磁板的另一侧。从截面上看，第一导磁件231、第二导磁件232、以及导磁连接件233形成位于储物组件210外周的环圈。
在第一磁体部件221和第二磁体部件222分别布置在储物组件210的顶壁、底壁的实施例中，第一连接段235从第一磁体部件221的横向一侧(例如右侧)的中部沿储物空间的一侧侧壁延伸至第二磁体部件222的对应一侧(例如右侧)的中部；第二连接段236从第一磁体部件221的横向另一侧(例如左侧)的中部沿储物空间的另一侧侧壁延伸至第二磁体部件222的另一侧(例如左侧)的中部。
导磁连接件233可以为条状，第一连接段235和第二连接段236沿前后纵深方向的宽度为导磁组件230沿前后纵深方向的长度的二分之一至十分之一。也即导磁连接件233设置在储物组件210前后方向的中部位置。
上述导磁组件230的构造，可以在满足磁场强度要求的情况下，减少导磁材料以及磁性部件的使用，节省磁场保鲜储物容器200的成本，并且可以减小磁场保鲜储物容器200以及冰箱10整机的重量。磁场的强度范围可以设置为1Gs-100Gs，在应用于冷冻环境的情况下，磁场强度范围可以优选采用5～60GS，例如可选择20Gs左右；在应用于冷藏环境的情况下，磁场强度范围可以采用20～160GS，优选地可以采用40～80Gs，例如60Gs左右。
图5是图2所示的磁场保鲜储物容器200的磁场方向示意图。第一磁体部件221与第二磁体部件222的磁场方向设置为相同，使得储物空间内形成均匀的磁场。也就是第一磁体部件221与第二磁体部件222的永磁板的N极朝向一个方向，而S极均朝向相反的方向。在第一磁体部件221和第二磁体部件222分别布置在储物组件210的顶壁、底壁的实施例中，储物空间内的磁场方向可以为从顶至底或者从底至顶。图5中示出的磁场方向为从底至顶，基于相同的技术思路，本领域技术人员易于通过调整磁极方向实现相反方向的磁场，也即实现从顶至底的磁场。
上述永磁板形成的永磁磁场为静态磁场，可以使得储物空间内始终具有一定强度的磁场。
基于上述对上下布置的第一磁体部件221与第二磁体部件222的说明，本领域技术人员易于在其他形状的储物组件210中实现第一磁体部件221和第二磁体部件222的左右布置，或者前后布置。
图6是根据另一实施例的磁场保鲜储物容器200的磁场方向示意图，而图7是6所述的磁场保鲜储物容器200中磁体组件220与导磁组件230的配合示意图。在该实施例中第一磁体部件221和第二磁体部件222的左右布置，第一磁体部件221(图6、7中被遮挡，未能示出)布置于储物组件210的右侧；第二磁体部件222布置于储物组件210的左侧。相应地，第一导磁件231的导磁板位于第一磁体部件221的右侧，第二导磁件232位于第二磁体部件222的左侧。导磁连接件233从储物组件210的顶部中央以及底部中央连接第一导磁件231和第二导磁件232。图6中示出的磁场方向为从右至左，基于相同的技术思路，本领域技术人员易于通过调整磁极方向实现相反方向的磁场，也即实现从左至右的磁场。
相类似地，本领域技术人员应易于实现第一磁体部件221和第二磁体部件222前后布置的实施例。
为了进一步提高磁场强度并使得磁场可调，本实施例还提供了一种能够生成电磁场与永磁场配合的磁场保鲜储物容器200。
图8是根据本发明又一实施例的磁场保鲜储物容器200的示意图；图9是图8所示的磁场保鲜储物容器200的部件爆炸图；图10是图8所示的磁场保鲜储物容器200中磁体组件220与导磁组件230的配合示意图。
在该实施例中，第一磁体部件221和第二磁体部件222在永磁板223的基础上，进一步增加了电磁环圈224。永磁板223仍然设置于储物组件210对应的侧面外侧，并且永磁板223的形状与其对应的侧面的形状相一致。
第一导磁件231以及第二导磁件232的导磁板分别相对永磁板223设置，并且导磁连接件233从导磁板的边缘沿储物组件210的外侧延伸并连接至另一侧的导磁板。
储物空间在导磁板所在平面上的投影位于导磁板的范围内，永磁板223的尺寸小于或等于其相对的导磁板。也就是说导磁板可以等于或略大于储物组件210的相应侧面。在第一磁体部件221设置于储物组件210的顶壁，第二磁体部件222设置于储物组件210的底壁的实施例中，第一导磁件231的导磁板覆盖储物空间的顶面，而第二导磁件232的导磁板覆盖储物空间的底面。
永磁板223的尺寸可以小于对应的导磁板，并且可以与导磁板的中心一致，也即永磁板223可以贴靠于导磁板的中央区域。导磁板可以将永磁板223的磁场进行聚拢，使其进一步均匀。
第一磁体部件221以及第二磁体部件222还分别设置有电磁环圈224。电磁环圈224设置于永磁板223和导磁板之间或者设置于永磁板223与储物组件对应的侧面之间。电磁环圈224内沿环形周向绕设有电磁线圈。电磁线圈被通电后用于产生与对应的永磁板223的永磁磁场相叠加的电磁场。
电磁环圈224的外周轮廓与永磁板223的轮廓可以大体一致或者略小于永磁板223，也就是说所述电磁环圈224的尺寸小于或等于其相对的永磁板223的尺寸。
永磁板223、导磁板、电磁环圈224三者的中心相对，也即导磁板可以覆盖导磁板、电磁环圈224，扩大储物空间内的磁场覆盖空间，并且可以使得储物空间内的磁场更加均匀。
电磁环圈224内电磁线圈的匝数可以根据所需的磁场强度进行设置。电 磁环圈224形成的电磁场的方向可以设置为与永磁板223的永磁磁场的方向一致。在该实施例，导磁板还可以聚拢电磁场，提高储物空间中磁场的均匀性。
通过对电磁线圈的控制，电磁场可以根据需要设置为磁场方向和/或磁场强度恒定的静态磁场、磁场方向和/或磁场强度交变的交变磁场、间隔启动的脉冲磁场。上述磁场调整可以通过调整通向电磁线圈的电流来实现。在一些实施例中，电磁场可以根据储物空间内的储物环境以及被储藏物的储藏状态进行调整。在电磁场不启动的情况下，利用永磁板223的永磁磁场维持基础的磁场强度。
以下以储物组件210为扁平形状的抽屉结构为例，对上下布置第一磁体部件221与第二磁体部件222的结构进行介绍。本领域技术人员易于在此基础上实现第一磁体部件221和第二磁体部件222的左右布置，或者前后布置的结构。
第一磁体部件221设置于储物组件210的顶壁，第二磁体部件222设置于储物组件210的底壁，并且可以具有大体相同的构造及尺寸。第一磁体部件221的永磁板223与储物组件210的顶壁形状相一致，第二磁体部件222的永磁板223可以与储物组件210的底壁形状相一致。且导磁板的尺寸可以与储物组件210的对应侧面的尺寸大体一致。
第一导磁件231的导磁板布置于第一磁体部件221的永磁板223的上方，而第二导磁件232的导磁板布置于第二磁体部件222的永磁板223的下方。导磁板的尺寸大于或等于永磁板223，并且贴靠设置于永磁板223的中央区域。
第一磁体部件221的电磁环圈224可以夹设在第一导磁件231的导磁板以及永磁板223之间或者永磁板223与储物组件210的顶壁之间，第二磁体部件222的电磁环圈224可以夹设在第二导磁件232的导磁板以及永磁板223之间或者永磁板223与储物组件210的底壁之间。第一导磁件231的导磁板可以分散均匀第一磁体部件221的电磁环圈224的磁场，第二导磁件232的导磁板可以分散均匀第二磁体部件222的电磁环圈224的磁场，从而在储物空间内部形成均匀的磁场。
第一连接段235从第一磁体部件221的横向一侧(例如右侧)的中部沿储物空间的一侧侧壁延伸至第二磁体部件222的对应一侧(例如右侧)的中 部；第二连接段236从第一磁体部件221的横向另一侧(例如左侧)的中部沿储物空间的另一侧侧壁延伸至第二磁体部件222的另一侧(例如左侧)的中部。
第一连接段235和第二连接段236可以从导磁板的侧端面的中央沿储物组件210外侧延伸。
导磁连接件233可以为条状，其尺寸能够满足形成导磁通路的要求即可，节省导磁材料的使用，在节省成本的同时，减轻重量。
电磁场的方向可以设置为永磁磁场的方向一致，从而实现磁场的相互叠加，提高磁场强度。图11是图8所示的磁场保鲜储物容器200的磁场方向示意图。第一磁体部件221与第二磁体部件222的电磁场以及永磁磁场的磁场方向均设置为相同，使得储物空间内形成均匀的磁场。储物空间内的磁场方向可以为从顶至底或者从底至顶。图11中示出的磁场方向为从底至顶，基于相同的技术思路，本领域技术人员易于实现相反方向的磁场，也即从顶至底的磁场。
导磁组件230一方面可以提高磁场的均匀程度，还可以对储物空间外侧的磁场进行引导，避免磁场对储物组件210以外的其他部件造成影响。
永磁板223、导磁板、电磁环圈224、导磁连接件233的配合结构经过优化改进，可以使得结构紧凑，节省了占用空间，便于装配至储物组件210，有利于在冰箱10内使用。
图12是根据另一实施例的磁场保鲜储物容器200的磁场方向示意图，而图13是12所述的磁场保鲜储物容器200中磁体组件220与导磁组件230的配合示意图。在该实施例中第一磁体部件221和第二磁体部件222的左右布置，第一磁体部件221和第二磁体部件222分别包括电磁环圈224以及永磁板223。第一磁体部件221(图12、13中被遮挡，未能示出)布置于储物组件210的右侧；第二磁体部件222布置于储物组件210的左侧。相应地，第一导磁件231的导磁板位于第一磁体部件221的右侧，第二导磁件232位于第二磁体部件222的左侧。导磁连接件233从储物组件210的顶部中央以及底部中央连接第一导磁件231和第二导磁件232。图12中示出的磁场方向为从右至左，基于相同的技术思路，本领域技术人员易于通过调整磁极方向实现相反方向的磁场，也即实现从左至右的磁场。
相类似地，本领域技术人员应易于实现第一磁体部件221和第二磁体部 件222前后布置的实施例。
图14是根据本发明一个实施例的具有磁场保鲜储物容器200的冰箱10的控制系统框图。本实施例的冰箱10还可以将磁场控制与制冷控制相结合，保证食物在磁场环境中冻结，实现保鲜冷冻的效果。
冰箱10还可以选择设置储物温度传感器330、开闭检测器340、制冷控制器310中的一项或多项。储物温度传感器330用于检测储物空间内的储物温度，开闭检测器340用于检测储物空间的开闭状态。
开闭检测器340检测到储物空间被打开后，通过储物温度传感器330可以检测是否放入新的食材，或者原有食材是否需要重新冷冻。在制冷过程中，电磁环圈224和制冷系统320配合，可以实现磁场辅助冷冻，提高食材的冷冻保鲜效果。
控制器310用于对电磁环圈224以及制冷系统320进行控制，从而实现相应的制冷以及磁场控制。而各种传感器(包括储物温度传感器330、开闭检测器340)，为上述控制提供了检测手段，从而可以满足控制方法的控制需求。
控制器310可以配置成根据储物空间的温度以及冰箱10的运行状态，控制电磁环圈224生成电磁场，例如磁场方向和/或磁场强度恒定的静态磁场、磁场方向和/或磁场强度交变的交变磁场、间隔启动的脉冲磁场。考虑到磁场在被储藏物的特定储藏阶段作用更大，控制器310可以在需要更强磁场时，启动电磁场；在正常储藏室，利用永磁场维持基本磁场强度。
例如利用磁场实现辅助冷冻储物时，控制器310可以配置成在储物空间放入新的被储藏物且储物温度在设定的温度阈值范围内时，启动电磁场。上述温度阈值范围可以根据对冻结过程中结晶时的温度进行设置，从而在完成结晶的过程中加大磁场强度。另外在正常储物过程中，永磁磁场保持一定的磁场强度，电磁场可以周期性地启动，对被储藏物进行加强磁场处理。上述控制方式可以使得被储藏物在强磁场环境中冻结，优先抑制冰晶晶核生长，减小对细胞造成的损伤，避免汁液流失，保证了食材更好的口感，提高了冷冻储物质量，满足了用户对珍贵食材的储藏质量要求。
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。
