Description

在门体上设置密封抽屉的冰箱 技术领域
本发明涉及冰箱，特别是涉及一种在门体上设置密封抽屉的冰箱。
背景技术
现有冰箱一般利用箱体形成储物空间，并通过门体对该储物空间进行开闭。这种传统的空间结构，对空间的划分不够灵活，特别是大容量冰箱，会导致储物空间无法充分利用；另一方面用户开关门体进行物品取放操作，也容易造成冷量泄露。
为了充分利用冰箱空间，现有技术中出现门中门结构，也即在门体包括内层门(或称为主门体、第一门)和外层门(或称为外门体、第二门)。内层门用于封闭箱体空间，并且内层门自身也具有储物空间。外层门用于封闭内层门上的储物空间。在用户需要取放内层门上的物品时，只需要打开外层门，提高了储物空间的布局灵活性。
然而现有的门中门冰箱，内层门上的储物空间一般仍直接与箱体储物空间直接连通，在开启外层门后，箱体储物空间的冷量仍然容易泄露。而且内层门储物空间与箱体储物空间也容易串味，由于门体开启相比于箱体储物空间开启更加频繁，更容易导致储藏物品的品质下降。
发明内容
本发明的一个目的是要提供一种在门体上提供密封、独立的密封抽屉，以供保存特殊食材的冰箱。
本发明一个进一步的目的是要延长食材的保质期，改善保鲜效果。

图1是根据本发明一个实施例的在门体11上形成储物空间的冰箱10的示意性透视图。该在门体11上形成储物空间的冰箱10一般性地可包括：箱体12、门体11。
箱体12内至少限定有第一储物空间(被门体11遮挡，未在图中示出)，第一储物空间具有前向开口。一般来说，箱体12内限定有至少一个前侧敞开的储物空间，通常为多个，按照制冷温度以及功能可分为冷藏室、冷冻室、变温室等等。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。上述第一储物空间可以为箱体12限定出多个储物空间中的一个或多个。
门体11，设置于箱体12前侧，用于开闭储物间室。例如门体11可以通过铰接的方式设置箱体12前部的一侧，通过枢转的方式开闭箱体12。门体11可以根据箱体12的布局进行配置。箱体12的布局结构可以根据冰箱的功能和需求进行配置，例如设置为对开门、T型(十字对开)、法式(四门、多门)等多种形式。
门体11可以包括：第一门200(或称为主门体或者内层门)以及第二门110(或称前门体或外层门)。第一门200可枢转地设置于前向开口的前部，其内可以限定出第二储物空间210。第二门110可枢转地设置于第一门200 框远离箱体12的一侧，并用于开闭第二储物空间210的开口。在第二门110单独开启时，可以显露出第二储物空间210。另外第二门110还可随第一门200同时开启，从而可以显露出箱体12限定的第一储物空间。由于双层门的铰链和旋转结构本身为本领域技术人员所习知，在本实施例中不做过多赘述。
在本实施例的在门体11上形成储物空间的冰箱10中，箱体12限定出的第一储物空间具有前向开口，并且通过双层门(或称为门中门)来封闭该第一储物空间。图2是根据本发明一个实施例的在门体11上形成储物空间的冰箱10中门体11的一个角度的示意图。图3是根据本发明一个实施例的在门体11上形成储物空间中冰箱10的门体11的另一角度的示意图。图2和图3分别示出了在第二门110打开状态下门体11的前侧结构以及后侧结构。
在本实施例的冰箱10中，第二储物空间210与第一储物空间相对独立。在第二门110单独打开时，可以避免第一储物空间的冷量泄露。在正常储物过程中也可以避免第一储物空间与第二储物空间210之间串味。
第一门200朝向前向开口的一侧开设有送风口223，并利用送风口223将第一储物空间的低温气体引入第二储物空间210，以对第二储物空间210内部制冷。送风口223处还可以增设风机以及杀菌装置，满足第二储物空间210的制冷要求。
第二储物空间210可以分隔为多个储物区域。储物区域的个数以及结构可以根据储物需求进行设置。在一些实施例中，其中至少一个储物区域可以被构造成密封抽屉300，该密封抽屉300可以用于实现干区存储、保鲜存储等。密封抽屉300可以为一个或多个，具体数量可以根据储物需求进行配置。
在本实施例的冰箱10中，第二储物空间210以及后侧的第一储物空间可以均配置为冷藏储物空间。通过分区，满足不同物品的储藏需要。
密封抽屉300包括密封桶体310以及可抽拉地设置于密封桶体310内的抽拉盒320。其中密封桶体310设置在第一门200内，并在远离第一储物空间一侧形成开口，也即开口位于第一门200朝向第二门110的一侧。抽拉盒320通过开口可抽拉地设置于密封桶体310内。
图4是根据本发明一个实施例的冰箱10中密封抽屉300的示意图。图5是根据本发明一个实施例的冰箱10中密封抽屉300的另一角度的示意图。 图6是是根据本发明一个实施例的冰箱10中抽换气部件的示意框图。
冰箱10设置有一换气装置340，设置于密封桶体310内，并配置成开启时使得密封桶体310内部空间与第一储物空间连通，以实现密封桶体310内部空间与第一储物空间之间进行气体交换。
本实施例的冰箱10优选采用风冷方式制冷，在第一储物空间制冷时，其内部湿度会下降。因此通过换气装置340可以在密封桶体310内的空气湿度大于第一储物空间内的空气湿度开启，降低密封桶体310内的空气湿度。
本实施例中，可以利用湿度检测装置检测箱体12内以及第一门200内的湿度。其中第一湿度检测装置331设置于第一储物空间内，并用于检测第一储物空间内的空气湿度。第二湿度检测装置332设置于密封桶体310内，并用于检测密封桶体310内的空气湿度。换气装置340还配置成在密封桶体310内的空气湿度大于第一储物空间内的空气湿度时开启。从而在密封抽屉300湿度较大时，通过与第一储物空间换气降低密封抽屉300的湿度，延长食材的保质期，改善保鲜效果。
为了进一步满足密封抽屉300储藏茶叶或者其他干货珍品的要求，本实施例的冰箱10还可以设置抽气装置350。抽气装置350设置于密封桶体310内，并配置成在密封桶体310内的空气湿度小于第一储物空间内的空气湿度后开启，对密封桶体310进行抽真空操作。
为了提高密封桶体310的可用容积，本实施例的冰箱还对密封桶体310的构造进行了优化。密封桶体310在靠近第一储物空间一侧设置有容纳腔，容纳腔与抽拉盒320所在的区域利用分隔壁进行分隔；抽气装置350以及换气装置340分别布置于容纳腔内。为了示出容纳腔的内部构造，图5中特意隐去了容纳腔的后壁。容纳腔可为长条形，设置于密封桶体310的顶部或底部，其内部提供了安装抽气装置350以及换气装置340的空间。分隔壁312上可以开设有用于使抽气装置350以及换气装置340连接至密封桶体310内部的通孔。
抽气装置350可以包括：单向阀351、真空泵352。单向阀351设置于分隔壁312上，并配置成仅允许抽拉盒320所在的区域的空气向容纳腔的一侧流动，从而避免了外部空气通过分隔壁312进入密封桶体310。真空泵352横向设置于容纳腔内，通过抽气管(图中未示出)与单向阀351位于容纳腔的一侧相连。
换气装置340可以包括换气阀341，设置于容纳腔朝向第一储物空间的腔壁上；换气管(图中未示出)从换气阀341延伸至分隔壁312，与抽拉盒320所在的区域连通。
上述换气装置340和抽气装置350均配置成仅在第一门200和第二门110均处于关闭状态下才被允许启动，以避免开门后外部空气影响第一湿度检测装置331和第二湿度检测装置332的湿度检测结果。本实施例的冰箱还可以设置有开关门检测器333。开关门检测器333，配置成感应第一门200和第二门110的开闭状态，从而为换气装置340和抽气装置350提供第一门200和第二门110的开闭状态。开关门检测器333可以使用触点开关、霍尔器件、磁敏器件等手段来检测第一门200和第二门110的开合动作。
本实施例的冰箱保持密封桶体310湿度的工作原理为：确定第一门200和第二门110均处于关闭状态，获取第一湿度检测装置331检测得到的第一储物空间内的空气湿度以及第二湿度检测装置332检测得到的密封桶体310内的空气湿度；对比第一储物空间内的空气湿度和密封桶体310内的空气湿度；若第一储物空间内的空气湿度大于密封桶体310内的空气湿度，则关闭换气阀341，启动真空泵352对密封抽屉300进行抽气。当密封桶体310内的空气湿度高于冷藏室空气湿度时，打开换气阀341，启动真空泵352对抽屉300进行换气。抽气和/或换气时间均可按预设时长进行，也可以根据温度启停。
第一储物空间内的空气湿度与密封桶体310内的空气湿度的比对以及对换气装置340和抽气装置350的控制，均可以通过一控制器完成。
本实施例中利用湿度检测装置分别检测箱体12的第一储物空间内的湿度以及密封桶体310内的湿度，利用换气装置340和抽气装置350来降低密封抽屉300的湿度。也即抽拉盒320关闭时通过真空抽湿技术降低抽屉300内湿度，保持抽屉300内处于干燥状态，有利于珍品的储藏。
本实施例为了保证密封效果，还对密封抽屉300的密封结构进行了改进。图7是根据本发明一个实施例的冰箱10中抽拉盒320关闭状态下的示意图，图8是图7示出的状态下密封件324的形态。图9是根据本发明一个实施例的冰箱10中抽拉盒320被拉出状态下的示意图，图10是图9示出的状态下密封件324的形态。
从图7至10中可以看出，密封件324设置于抽拉盒320的面板与密封 桶体310相对的位置处，并且密封件324在抽拉盒320关闭时被抽拉盒320的面板以及密封桶体310挤压，以对抽拉盒320的面板与密封桶体310之间的缝隙进行密封。密封件324可以使用硅胶密封垫圈，嵌设在抽拉盒320前面板开设的沟槽内。在抽拉盒320关闭后，在抽拉盒320前面板和密封桶体310前表面的挤压下，密闭抽拉盒320与密封桶体310之间的缝隙。
为了便于用户操作，防止密封状态下抽拉盒320难以被打开，抽拉盒320还可以包括枢转把手321。该枢转把手321包括：两枢转臂322以及拉杆323。两枢转臂322一端分别与抽拉盒320的前面板的两侧在设定旋转角度内枢转连接；拉杆323连接于两枢转臂322的另一端，并在枢转臂322转动至设定角度后，供用户抓持以施加抽拉抽拉盒320的力。枢转把手321在正常状态下可以贴合于抽拉盒320的面板前侧，再被用户拉动反转后，可以基本与抽拉盒320的面板垂直，从而便于用户施力。枢转把手321的设定旋转角度可以由角度限位部件限定，例如限定为与抽拉盒320面板的夹角为0-90度。
图11是根据本发明一个实施例的冰箱10中抽拉盒320被拉出时锁紧件325的状态图，图12是根据本发明一个实施例的冰箱10中抽拉盒320被关闭时锁紧件325的状态图。
为了进一步提高密封性，上述冰箱还包括：锁紧件325，用于在抽屉300关闭时限定抽拉盒320的面板以及密封桶体310的位置。锁紧件325可以与枢转把手321联动设置，在枢转把手321被拉出时解除锁定；在枢转把手321被放回时锁定密封桶体310和抽拉盒320的位置。
锁紧件325可以采用限位柱326和限位槽327的配合结构。限位柱326，从设置于密封桶体310的两侧的前端向抽拉盒320的面板伸出；限位槽327开设于抽拉盒320的面板的两侧，与限位柱326配合锁定抽拉盒320的位置。限位槽327具有朝向密封桶体310的水平段，供限位柱326沿抽拉盒320的抽拉方向进入，限位槽327在末端具有沿高度方向的容纳槽，限位柱326到达水平段的末端后，沿高度方向进入容纳槽，实现锁定。在拉出抽拉盒320时，用户抬起枢转把手321，限位柱326脱出容纳槽，沿沿抽拉盒320的抽拉方向可脱出容纳槽。锁紧件325可以为多组，密封桶体310的两侧可以分别设置多组锁紧件325。
利用上述结构，密封抽屉300通过密封件(如硅胶密封垫圈)挤压实现密封，并且通过结构改进，利用枢转把手321即可方便的密封和解锁，便于 用户操作。
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。
