Description

磁场保鲜储物容器和冰箱 技术领域
本发明涉及冷藏冷冻设备，特别是涉及一种磁场保鲜储物容器和冰箱。
背景技术
用户对冰箱储藏物的保鲜效果也越来越重视，对于肉类、鱼、虾这类食材，储藏过程中容易出现汁液流失导致口感变差、颜色变暗的问题。特别是某些高档食材，储藏一段时间后的品质会大为降低。
理论研究发现磁场对冷冻过程中冰晶的形成有较大的影响。目前冰箱领域也积极探索将磁场引入保鲜储物，然而在冰箱中实际应用时，磁性部件除了在储物空间内产生磁场，以提高被储藏物的保鲜储藏质量，还会扩散至储物空间以外。长期使用可能会导致周围部件被磁化，影响使用者的正常使用。

特别地，本发明提供了一种磁场保鲜储物容器，其包括：
储物盒，其内限定用于放置被储藏物的储物空间；
一个或多个导磁环带，分别套设于储物盒的外周；

每个磁性件包括电磁环圈以及永磁板，电磁环圈内部沿环形周向绕设有电磁线圈并在通电后形成电磁场，永磁板设置在电磁环圈的中央通孔处或者贴靠电磁环圈设置，并用于产生与电磁场的磁场方向一致的永磁磁场。
可选地，上述磁场保鲜储物容器还包括：
筒体，具有前向开口；

图1是根据本发明一个实施例的磁场保鲜储物容器200的冰箱10的示意性透视图。本实施例的冰箱10一般性地可以包括箱体120、门体110、制冷系统(图中未示出)。箱体120内可以限定有至少一个前侧敞开的储物间 室，通常为多个，如冷藏储物间室、冷冻储物间室、变温储物间室等等。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。
本实施例的冰箱10可以为风冷冰箱，在箱体120内设置有风路系统，利用风机将经过换热器(蒸发器)换热的制冷气流经送风口送向储物间室，然后经由回风口返回风道。实现制冷。由于此类冰箱的箱体120、门体110、制冷系统本身均是本领域技术人员习知且易于实现的，为了不掩盖和模糊本申请的发明点，后文对箱体120、门体110、制冷系统本身不做赘述。
冰箱10的一个或多个储物间室内部可以设置有磁场保鲜储物容器200。磁场保鲜储物容器200在放置于冷冻储物间室时，可以用于对冷冻食材进行冷冻保鲜，抑制冰晶晶核生长，使得冰晶生长速率高于水分子迁移速率，产生的冰晶偏小，从而减小对细胞造成的损伤，避免汁液流失，加速冷冻过程，缩短冻结时间。磁场保鲜储物容器200在放置于冷藏储物间室时，可以降低食材氧化还原反应的速度，减少营养、水分损失，阻止食材变色，抑制细菌滋生，延长食材保鲜期。
磁场保鲜储物容器200的数量以及布置的储物间室，可以根据用户需求进行配置。例如冰箱10内可以设置一个或多个磁场保鲜储物容器200。磁场保鲜储物容器200可以布置于冷藏储物间室、冷冻储物间室、变温储物间室当中，在上述储物间室内进行磁场辅助保鲜。磁场保鲜储物容器200也可以作为冰箱10的一个独立间室，由冰箱10对其独立控温。
图2是根据本发明一个实施例的磁场保鲜储物容器200作为冰箱抽屉的示意图。
磁场保鲜储物容器200一般性地可以包括：储物盒210、一个或多个导磁环带230、以及多个磁性件220。储物盒210内限定用于放置被储藏物的储物空间212，储物盒210可以为盒体状。一些实施例中储物盒210可以为整体扁平的长方体形状(即沿高度方向的距离明显小于沿纵深方向的距离以及沿横向左右方向的距离)。储物盒210可以为抽屉结构。
磁场保鲜储物容器200还可以包括筒体211。筒体211具有一前向开口。储物盒210为抽屉，可抽拉地设置在筒体211内。储物盒210的顶部具有用于取放物品的取放口，在被拉出筒体211后，取放口被显露。储物盒210被推入筒体211后，可以形成独立的储物空间212内。储物盒210具有前端盖214，前端盖214与筒体211前端的框体抵接，前端盖214与筒体211之间 可以设置密封结构，使得储物空间212相对密封。磁场保鲜储物容器200上还可以设置送风口以及回风口(图中未示出)，用于将外部制冷气流引入磁场保鲜储物容器200内，经过换热后重新送回储物盒210外部。送风口以及回风口的位置可以根据冰箱10的送风风道、回风风道以及储物间室的构造进行设置。由于冰箱内部的抽屉本身构造以及制冷方式本身为本领域技术人员所习知，本实施例后续描述不做赘述。
一个或多个导磁环带230分别套设于储物盒210的外周。导磁环带230可以沿储物盒210的上下左右侧进行环绕，也即沿储物盒210的纵向方向环绕。可替代地，导磁环带230也可以沿储物盒210的前后左右侧进行环绕，也即沿储物盒210的横向方向环绕。对于在储物盒210整体为扁平形状的结构，特别是储物盒210为抽屉形式的情况下，导磁环带230可以沿储物盒210的纵向方向环绕。在布置多个导磁环带230的情况下，多个导磁环带230可以间隔设置，从而形成多条导磁环路，并且使得磁场分布更加均匀。
导磁环带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，减少对储物盒210外侧的其他部件造成干扰(例如避免磁化其他部件等)。导磁环带230可以使用硅钢片或类似材料制成。导磁环带230的尺寸可以根据对磁场分布的测试确定，要求满足聚集磁场的条件。在一些实施例中，导磁环带230的宽度可以占储物盒210整体长度的二分之一至十分之一。例如导磁环带230沿储物盒210的纵向方向环绕的实施例中，导磁环带230沿前后纵深方向的宽度可为储物盒210沿前后纵深方向的长度的二分之一至十分之一；又例如导磁环带230沿储物盒210的纵向方向环绕的实施例中，导磁环带230沿上下高度方向的宽度可为储物盒210沿上下高度方向的长度的二分之一至十分之一。
导磁环带230沿储物盒210的纵向方向环绕的实施例中，多个导磁环带230可以沿储物盒210的前后纵深方向间隔布置。若导磁环带230为一个，则该导磁环带230可以设置于储物盒210的前后纵深方向的中部区域，并与两个磁性件220的前后纵深方向的中部相对。导磁环带230的数量以及具体的位置可以根据磁场的范围以及强度进行设置。对于储物空间212较小的储物盒210，可以在中部设置在一个导磁环带230；对于储物空间212较大的储物盒210，可以间隔设置多个导磁环带230。
相比于在磁场外围设置包围储物盒210外周的屏蔽装置，本实施例的磁 场保鲜储物容器200利用较小的导磁环带230实现导磁通路，可以在满足磁场强度要求的情况下，减少导磁材料的使用，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。
多个磁性件220分别设置于储物盒210与一个或多个导磁环带230之间，并用于在储物空间212中形成磁场，并利用一个或多个导磁环带230在储物空间212外部形成环形的导磁通路。磁性件220作为磁场的生成源。磁性件220可以为板状，相对于储物盒210的盒壁设置。导磁环带230围绕设置在磁性件220的外侧。
在一些实施例中，导磁环带230可以具有与磁性件220互相抵靠的部分，从而将远离于储物空间212的磁场进行聚集，完成磁场的闭合。
磁性件220可以为两个，分别设置于储物空间212一组相对侧面上，特别适宜于长方体状的储物空间212。两个磁性件220所在的相对侧面可以根据储物盒210的自身形状以及在冰箱10内的位置进行选择，例如可以选择放置在储物盒210的横向两侧、顶底两侧、或者前后两侧。在导磁环带230沿储物盒210的上下左右侧进行环绕的情况下，磁性件220分别布置在储物盒210的顶面和底面或者磁性件220分别布置在储物盒210的横向左侧面或者横向右侧面。
每个磁性件220的形状与其所在的侧面的形状大体一致，保证磁场可以均匀地覆盖储物空间212。在一些实施例中，储物空间212在磁性件220所在平面上的投影可以位于磁性件220的外周轮廓范围内。也就是说磁性件220可以等于或略大于储物组件210的相应侧面。在磁性件220设置于储物盒210的顶部和底部的情况下，顶部磁性件220可以分别覆盖储物空间212的顶面；与底部磁性件220分别覆盖储物空间212的底面。
磁性件220可以使用永磁部件也可以使用电磁部件。图3是根据本发明一个实施例的磁场保鲜储物容器200中磁性件220的示意图。在该实施例中，磁性件220包括电磁环圈221。电磁环圈221内部沿环形周向绕设有电磁线圈，电磁线圈被通电后使储物空间中形成电磁场。电磁环圈221可以成型为一个扁平环状，顶部和底部均为平面状，并且厚度明显小于外周尺寸。电磁环圈221的宽度与厚度的比值范围可以设置为1-10。上述结构的电磁环圈221可以更方便地与储物盒210以及导磁环带230配合，占用空间更小。电磁环圈221具有有相应的防水结构，例如利用浸漆、塑封、密封圈或密封外 壳包裹保护内部的电磁线圈，整体构造成扁平的环状。
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212内的储物环境以及被储藏物的储藏状态进行调整。
图4是根据本发明另一实施例的磁场保鲜储物容器200中磁性件220的示意图。磁性件220可以同时包括永磁部件222和电磁部件221(如电磁环圈)，利用永磁部件222提供基础的永磁磁场，而电磁部件221被通电后，可以形成与永磁磁场叠加的电磁磁场。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。永磁部件222可以为永磁板222。也就是说每个磁性件220包括电磁环圈221以及永磁板222，电磁环圈221内部沿环形周向绕设有电磁线圈并在通电后形成电磁场。永磁板222设置在电磁环圈221的中央通孔处或者贴靠电磁环圈221设置，并用于产生与电磁场磁场方向的一致的永磁磁场。
永磁板222除了提供永磁磁场之外，还可以使得电磁场更加均匀。电磁环圈221以及永磁板222同中心设置。永磁板222的尺寸可以大于电磁环圈221的外周轮廓，从而扩大电磁场的覆盖范围。上述永磁板222形成的永磁磁场为静态磁场，可以使得储物空间212内始终具有一定强度的磁场。
电磁环圈221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221形成的电磁场的方向可以设置为与永磁板222的永磁磁场的方向一致。在该实施例中，永磁板222还可以扩散电磁场的范围，提高储物空间中磁场的均匀性。
通过对电磁线圈的控制，电磁场也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222的永磁磁场维持基础的磁场强度。
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。在图2示出的磁性件220设置于储物空间顶部和底部的情况下，储物空间212内的磁场方向可以为从顶至底或者从底至顶。本领域技术人员易于通过改变磁极方向实现相反方向的磁场。
图2示出的结构中，磁性件220设置在储物盒210的顶部和底部，本领域技术人员易于通过上述说明实现将磁性件220设置在储物盒210的横向左右两侧的结构。
另外磁性件220以及导磁环带230可以设置在筒体211的外侧，考虑到电磁环圈221在通电产生磁场的过程中会发热，磁性件220与储物空间212内被储藏物的距离可以设置为不小于1mm。也即利用筒体211还可以在一定程度上避免电磁环圈221发热对被储藏物的影响，并且也便于对电磁环圈221散热。
可替代地，磁性件220以及导磁环带230也可以设置在筒体211的内部，例如导磁环带230也可以设置于筒体211的内部，并在内侧设置磁性件220。
图5是根据本发明一个实施例的磁场保鲜储物容器200的示意图。图6是图5所示的磁场保鲜储物容器200的部件爆炸图。该磁场保鲜储物容器200具有两个导磁环带230以及两个磁性件220。为了示出导磁环带230与磁性件220的配合关系，图5及图6中省略了储物盒210，仅仅示出了用于放置储物盒210的筒体211。。
两个磁性件220分别放置在磁场保鲜储物容器200的顶部以及底部。其中顶部的磁性件220覆盖储物空间的顶面，底部的磁性件220覆盖储物空间的底面，其产生的磁场方向在储物空间内从底至顶或者从顶至底，具体的磁场方向可以通过调整磁极的方向实现。
两个导磁环带230分别沿筒体211的上下左右环绕。其中一个导磁环带230靠前设置，另一个导磁环带230靠后设置。靠近储物盒210的前部的外侧磁场被靠前的导磁环带230所聚拢，使得储物盒210前部的磁场闭合。靠近储物盒210的后部的外侧磁场被靠后的导磁环带230所聚拢，使得储物盒210后部的磁场闭合。两个导磁环带230可以对磁场进行分散，使得储物空间内的磁场更加均匀，避免中央区域的磁场强度明显高于周围区域。
图7是根据本发明另一实施例的磁场保鲜储物容器的示意图；图8是图7所示的磁场保鲜储物容器的部件爆炸图。该磁场保鲜储物容器200具有一 个导磁环带230以及两个磁性件220。为了示出导磁环带230与磁性件220的配合关系，图7及图8中同样省略了储物盒210。
两个磁性件220分别放置在磁场保鲜储物容器200的顶部以及底部。其中顶部的磁性件220覆盖储物空间的顶面，底部的磁性件220覆盖储物空间的底面，其产生的磁场方向在储物空间内从底至顶或者从顶至底，具体的磁场方向可以通过调整磁极的方向实现。
导磁环带230沿筒体211的上下左右环绕并位于储物盒210靠近中央的位置，向储物空间外部延伸的磁场被导磁环带230所聚拢，减少了对外部其他部件的磁场影响。
上述导磁环带230的数量可以根据导磁环带230的数量以及具体的位置可以根据磁场的范围以及强度进行设置。对于储物空间212较小的储物盒210及筒体211，可以在中部设置在一个导磁环带230；对于储物空间212较大的储物盒210及筒体211，可以间隔设置两个或者更多个导磁环带230。
另外，上述附图中示出的磁性件220分别布置在筒体211的顶部或底部，在一些其他可替代实施例中，磁性件220也可以分别布置在筒体211的左右两侧。在另一些其他可替代实施例中，例如对于非抽屉型的储物盒，导磁环带230也可以沿储物盒210的前后左右方向环绕设置。
图9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，磁性件220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用于对磁性件220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，控制磁性件220中的电磁环圈221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，利用静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。
