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。
为了提高储物的质量，现有技术中出现了较多的改进方案，但是有些保鲜储藏效果不够理想，有些实现成本高，不便于在家用冰箱中应用。在上述改进方案中，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。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，储物空间内的磁场分布不均，而磁场强度对保鲜效果存在较大的影响，保鲜空间内磁场分布不均导致被储藏物的储藏质量难以保证。
发明内容
本发明的一个目的是要提供一种有效提高储物质量的磁场保鲜储物容器和冰箱。
本发明一个进一步的目的是要使得储物空间内的磁场更加均匀。
本发明另一进一步的目的是要降低部件成本。
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；
两块匀磁板，由导磁材料制成，并分别与储物盒相对设置的一组侧壁对应设置；
两组电磁组件，每组电磁组件与一块匀磁板对应设置，并在通电后形成电磁场，并利用匀磁板改变电磁场的磁场分布，使得电磁场在储物空间内分布更加均匀。
可选地，每块匀磁板朝向储物盒的一侧设置有一个或多个凸台；每组电磁组件包括一个或多个电磁环圈，每个电磁环圈套设于一凸台上，其内部沿环形向轴线绕设有电磁线圈。
可选地，匀磁板的形状与其所在的储物盒的侧壁形状相适配，并且储物 空间在匀磁板所在平面上的投影位于匀磁板的外周轮廓范围内。
可选地，每块匀磁板上设置一个凸台，并且凸台位于匀磁板的中央区域，并使得凸台上套设的电磁环圈的中心与匀磁板的中心大体相对。
可选地，每块匀磁板上设置间隔设置有多个凸台，每个凸台上套设一个电磁环圈。
可选地，每块匀磁板覆盖所在的储物盒的侧壁的部分区域，并且其中心与侧壁的中心相对，并其在朝向储物盒的一侧设置有凸出部；每组电磁组件包括一电磁环圈，电磁环圈的内周壁的部分区段与凸出部抵靠。
可选地，上述磁场保鲜储物容器还包括：导磁连接带，连接于两块匀磁板的两侧，并与两块匀磁板在储物空间外部形成环形的导磁通路。
可选地，上述磁场保鲜储物容器还包括：
筒体，具有前向开口；
储物盒为抽屉，可抽拉地设置在筒体内，并且两块匀磁板分别布置在储物盒的顶部以及底部。
可选地，匀磁板设置于筒体的外侧或者内侧，并且电磁组件与储物空间内被储藏物的放置区域的最小间隔设置大于1mm。
根据本发明的另一个方面，还提供了一种冰箱，其包括：
箱体，其内限定有储物间室；

本发明的磁场保鲜储物容器，两块匀磁板、两组电磁组件分别与储物盒相对设置的一组侧壁对应设置，匀磁板有导磁材料制成，可以改变电磁组件形成的电磁场的磁场分布，使得电磁场在储物空间内分布更加均匀。磁场有助于提高储物质量，可以缩短冻结时间，减少食物的汁液流失率以及营养流失，降低微生物和细菌数量，延长保鲜周期。由于磁场更加均匀，可以使得被储藏物具有统一储藏品质。同时匀磁板可以节省磁性材料的使用量，避免了使用过多或者过大的磁性件导致的成本上升以及重量增加。
进一步地，本发明的磁场保鲜储物容器，匀磁板朝向储物盒的一侧设置有凸台，利用凸台一方面可以对电磁组件进行限位，另一方面还可以便于磁场汇集进入匀磁板，提高了磁场利用效率。

更进一步地，本发明的冰箱，设置有上述磁场保鲜储物容器，使得食材在磁场环境中储藏，抑制冰晶晶核生长，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，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。
更进一步地，本发明的冰箱，通过磁场提高了储物质量，可以为智能冰箱提供新的保鲜功能，符合了使用者对智能冰箱日益提高的使用需求，进一步满足了使用者对智慧家庭、智能生活的品质要求。

附图说明

具体实施方式
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。
磁场保鲜储物容器200可以包括储物盒210。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)。本领域技术人员可以根据所需的储物空间配置储物盒210的构造和尺寸，利用配置为盒体状、箱体状、在一些实施例中可以用于实现抽屉结构。
图2是根据本发明一个实施例的抽屉结构的磁场保鲜储物容器200的示 意图。储物盒210可以为抽屉结构，也即磁场保鲜储物容器200还可以包括：筒体211。其中筒体211具有前向开口。储物盒210可抽拉地设置在筒体211内。储物盒210被拉出后可以显露出储物空间212，以便取放被储藏物。储物盒210被推入筒体211后，可以形成独立的密封空间内。用于冰箱的抽屉本身构造为本领域技术人员所习知，在此不做赘述。
磁场保鲜储物容器200的两块匀磁板221，由导磁材料制成，并分别与储物盒210相对设置的一组侧壁对应设置。匀磁板221可以由具有低矫顽力和高磁导率的材料制成，例如可以使用硅钢片或类似材料制成。匀磁板221所在的相对侧面可以根据储物盒210的自身形状以及储物空间212的构造进行选择，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。也就是说两块匀磁板221可以在储物盒210的横向左右两侧、顶面和底面两侧，或者前后两侧。
在储物盒210整体为扁平形状，特别是储物盒210为抽屉形式的情况下，两块匀磁板221可以优先布置为设置于储物盒210的顶底两侧。磁场保鲜储物容器200形成的磁场从顶至底或者从底至顶贯穿储物空间212。
磁场保鲜储物容器200具有两组电磁组件222。每组电磁组件222与一块匀磁板221对应设置，并在通电后形成电磁场，并利用匀磁板221改变电磁场的磁场分布，使得电磁场在储物空间212内分布更加均匀。在两块匀磁板221可以优先布置为设置于储物盒210的顶底两侧的情况下，两组电磁组件222相应地布置于储物盒210的顶底两侧。在匀磁板布置于储物盒其他相对侧壁的实施例，两组电磁组件222可以与匀磁板布置于相应的侧壁上。
满足保鲜要求的磁场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。也即匀磁板221以及电磁组件222能够在储物空间内形成全面覆盖的上述磁场强度范围的保鲜磁场。
图3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4是图3所示的磁场保鲜储物容器200的部件爆炸图。为了示出匀磁板221与电磁环圈223的配合关系，图5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。匀磁板221的形状与其所在的筒体211的侧壁形状相适配，并且储物空间在匀磁板平面上的投影可以位于匀磁板的外周轮廓范 围内。也即匀磁板221的尺寸可以等于或略大于储物盒210的相应侧面。在匀磁板221设置于筒体211的顶部和底部的情况下，顶部匀磁板221可以分别覆盖储物空间212的顶面；与底部匀磁板221分别覆盖储物空间212的底面。匀磁板221可以使得磁场在储物盒210内实现无死角的覆盖。
每块匀磁板221朝向储物盒210的一侧设置有一个或多个凸台224；每组电磁组件222包括一个或多个电磁环圈223，每个电磁环圈223套设于一凸台224上，其内部沿环形向轴线绕设有电磁线圈。如图3、4所示，顶部的匀磁板221具有朝下设置的凸台224，底部的匀磁板221具有朝上设置的凸台224。每块匀磁板221上设置一个凸台224，并且凸台224位于匀磁板221的中央区域。
电磁环圈223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212中形成电磁场。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。在另一些实施例中，电磁场也可以为磁场强度不变的恒定磁场。
电磁环圈223可以成型为一个扁平环状，两端面(顶面或底面)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223的宽度与厚度的比值范围可以设置为1-10。电磁环圈223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。上述结构的电磁环圈223可以更方便地与匀磁板221配合，占用空间更小。电磁环圈223套设于一凸台224上，其内部沿环形向轴线绕设有电磁线圈。凸台224的轮廓可以与电磁环圈223的内周通孔的形状相适配，使得电磁环圈223可以方便地安装在凸台224上。另外凸台224还可以使得电磁环圈223的磁场引导进入匀磁板221，利用匀磁板221改变电磁场的磁场分布。
电磁环圈223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223形成的电磁场垂直于储物盒210的侧壁，并且相对侧壁的电磁环圈223的磁极方向设置为一致，使得储物空间形成贯穿的磁场。也就是两个电磁环圈223的N极朝向同一方向，而S极均朝向相反的方向。例如磁场方 向可以为从顶至底或者从底至顶。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。
凸台224位于匀磁板221的中央区域，可以使得凸台224上套设的电磁环圈223的中心与匀磁板221的中心大体相对。凸台224一方面可以对电磁环圈223进行限位，另一方面还可以便于磁场汇集进入匀磁板221，提高了磁场利用效率。
凸台224的凸出高度可以与电磁环圈223的的厚度大体一致或者略小于电磁环圈223的厚度，以便匀磁板221和电磁环圈223与储物盒210(或筒体211)配合。
匀磁板221扩大了电磁环圈223的磁场范围，并得电磁场更加均匀。电磁环圈223以及匀磁板221同中心设置。匀磁板221的尺寸可以大于电磁环圈223的外周轮廓，从而扩大电磁场的覆盖范围。
图5是根据本发明另一实施例的磁场保鲜储物容器200的部件爆炸图。为了示出匀磁板221与电磁环圈223的配合关系，图5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。在该实施例的磁场保鲜储物容器200中，磁场保鲜储物容器200的两块匀磁板221也分别与储物盒210相对设置的一组侧壁对应设置，可以选择放置在筒体211的横向两侧、顶底两侧、或者前后两侧。匀磁板221的尺寸可以等于或略大于储物盒210的相应侧面。在匀磁板221设置于筒体211的顶部和底部的情况下，顶部匀磁板221可以分别覆盖储物空间212的顶面；与底部匀磁板221分别覆盖储物空间212的底面。匀磁板221可以使得磁场在储物空间212内实现无死角的覆盖。
每块匀磁板221上设置间隔设置有多个凸台224，每个凸台224上套设一个电磁环圈223。凸台224可以均匀分布于匀磁板221上。例如匀磁板221上可以布置两个或者四个相同的大小的凸台224，每个凸台224分别套设一个电磁环圈223。通过多个电磁环圈223可以分散磁场的分布，进一步提高磁场的均匀性。
上述凸台224以及电磁环圈223的数量可以根据储物空间212的尺寸进行配置，例如对于储物空间212较大的储物盒210，匀磁板221可以布置多个凸台224与多个电磁环圈223配合。对于储物空间212较小的储物盒210，匀磁板可以布置一个凸台224以一个电磁环圈223配合。
两侧的匀磁板221与电磁环圈223的组合可以具有大体相同的构造，从 而在储物空间212内形成贯穿的磁场。图5中示出的实施例，储物盒210顶部和底部的匀磁板221分布具有两个凸台224，并在储物盒210的顶部和底部分别设置两个电磁环圈223与之配合。在该结构的基础上，本领域技术人员易于实现更多个凸台224以及电磁环圈223进行配合。
图6是根据本发明另一实施例的磁场保鲜储物容器200的示意图；图7是图6所示的磁场保鲜储物容器200的部件爆炸图。为了示出匀磁板221与电磁环圈223的配合关系，图6与图7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。本实施例进一步减少了匀磁板221的尺寸，并减少了磁场保鲜储物容器200的重量。匀磁板221分别与储物盒210(或筒体211)相对设置的一组侧壁对应设置，每块匀磁板221覆盖所在的储物盒210(或筒体211)的侧壁的部分区域，并且其中心与侧壁的中心相对，并其在朝向储物盒210的一侧设置有凸出部225。每组电磁组件222包括一电磁环圈223，电磁环圈223的内周壁的部分区段与凸出部225抵靠。匀磁板221在对应储物盒210侧壁所在平面的投影可以位于储物盒210的中部区域。例如对于布置于筒体211顶部和底部的匀磁板221，匀磁板221的位置可以在筒体211上方前后方向的中部以及下方的前后方向的中部。
电磁环圈223的内周壁可以利用中部的区段与匀磁板221的凸出部225相配合，利用匀磁板221改变电磁场分布。
图8是根据本发明一个实施例的具有导磁连接带230的磁场保鲜储物容器200的示意图。磁场保鲜储物容器200还可以包括导磁连接带230，连接于两块匀磁板221的两侧，并与两块匀磁板221在储物空间212外部形成环形的导磁通路。导磁连接带230将匀磁板221在储物空间212外部连接成环形的导磁通路。导磁连接带230可以适用于匀磁板221同样材料制成，其形成的导磁通路可以用于聚拢磁场，提高储物空间212内磁场的均匀性，同时可以减少磁场向外部释放，减少对磁场保鲜储物容器200外部的其他部件造成干扰(例如避免磁化其他部件等)。
导磁连接带230与匀磁板221可以一体件，也即由相同的材料一体成形制成。在另一些实施例中，导磁连接带230与匀磁板221也可以通过拼接形成环形的导磁通路。
在匀磁板221与电磁环圈223分别布置在储物盒210(或筒体211)的顶部和底部的实施例中，导磁连接带230中的一段可以从顶部的匀磁板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底部的匀磁板221的对应一侧(例如右侧)的中部；另一段导磁连接带230从顶部的匀磁板221的横向另一侧(例如左侧)的中部沿储物空间212的另一侧侧壁延伸至底部的匀磁板221的另一侧(例如左侧)的中部。
导磁连接带230可以为条状，其沿前后纵深方向的宽度为匀磁板221沿前后纵深方向的长度的二分之一至十分之一。也即导磁连接带230可以设置在匀磁板221前后方向的中部位置，且明显窄于匀磁板221。上述导磁连接带230与匀磁板221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。
图9是根据本发明另一实施例的具有导磁连接带230的磁场保鲜储物容器200的示意图。匀磁板221覆盖所在的储物盒210的侧壁的中部区域，并且其中心与侧壁的中心相对。导磁连接带230从匀磁板221的端部沿筒体211的外侧连接至另一侧的匀磁板221，从而形成环形的导磁通路。导磁连接带230以及匀磁板221位于筒体211前后纵深方向的中央位置，从而在储物空间212的外侧形成导磁通路，避免磁场向外泄露。
在磁场保鲜储物容器200为抽屉结构的情况下，匀磁板221可以设置于筒体211的外侧，例如在筒体211顶面的上方以及筒体211底面的下方设置匀磁板221以及电磁组件222。考虑到电磁组件222在通电产生磁场的过程中会发热，电磁组件222与储物空间内被储藏物的距离可以设置为不小于1mm。匀磁板221和电电磁组件222可以设置于筒体211的外侧，可以减少电磁组件222对储物空间212内被储藏物的储藏温度的影响，有利于制冷气流对电磁组件222进行散热。
图10是根据本发明另一实施例的抽屉结构的磁场保鲜储物容器200的示意图。在该实施例中，磁场保鲜储物容器200为抽屉结构，匀磁板221以及电磁组件222设置于筒体211的内部，也即匀磁板221以及电磁环圈223设置于筒体211的顶面以及底面的内侧。筒体211的内表面上可以设置用于布置匀磁板221以及电磁组件222的结构。这种结构电磁组件222距离被储藏物的距离更近，有利于磁场对被储藏物施加磁场影响。考虑到电磁组件222在通电产生磁场的过程中会发热，电磁环圈223与储物空间212内被储藏物的距离可以设置为不小于1mm。也即电磁环圈223与被储藏物设置有不小 于1mm的间隙。
图11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212内的储物温度，开闭检测器340用于检测储物空间212的开闭状态。
开闭检测器340检测到储物空间212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223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223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；在正常储藏时，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212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。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。
