Description

冰箱 技术领域
本发明涉及冷藏冷冻技术领域，特别涉及一种冰箱。
背景技术
随着技术的进步和人们生活水平的提升，用户对于冰箱的要求越来越高。传统的仅设置冷藏室、冷冻室和变温室的冰箱已经不能满足用户对于存储空间多样化的需求。
近年来，冰箱领域出现了一种复合门体技术。众所周知，传统的冰箱门体用于开闭箱体的制冷间室，最多在冷藏门体的内衬处设置瓶座用于放置瓶装物。而复合门体的冰箱则对门体结构和功能进行改进，使门体包括主门和副门，主门用于开闭制冷间室。并且，主门限定出前侧敞开的门体间室，副门用于开闭门体间室。主门转动过程中，副门保持关闭状态。门体间室可供放置存储物，且取放时仅需打开副门，无打开主门。不仅使操作更加方便快捷，而且避免频繁打开主门引起冷量过多损耗。
但是，复合门冰箱也存在很多缺陷，例如门体间室空间太小，温度不易控制，存储条件与冷藏室雷同，甚至与冷藏室完全相通，成为冷藏室的一部分。这些问题都会对用户体验产生负面影响，阻碍了复合门技术的进一步发展。
发明内容
本发明的目的是要至少解决现有技术存在的上述缺陷之一，提供一种使门体的间室温度独立于箱体的间室温度的冰箱。
本发明的另一目的是要使门体的间室各处的温度分布更加均衡。
特别地，本发明提供了一种冰箱，包括：

门体，用于开闭第一间室且限定出第二间室，门体还限定有一围绕在第二间室外侧的方环状风道，风道包括分别位于第二间室上侧、横向两侧和下侧的进风段、两个送风段和出风段；且
进风段具有用于引入冷气的进风口，送风段具有用于向第二间室输送冷气的送风部，出风段具有用于排出风道内剩余冷气的出风口。
可选地，第二间室分隔为多个子间室，每个子间室均匹配至少一个送风部。
可选地，每个子间室匹配两个送风段上的送风部。
可选地，送风部包括电动风门，以便对从送风段进入第二间室的冷气的流量进行调节。
可选地，门体配置成在自身处于关闭状态时，使进风口和出风口均位于第一间室内，以允许风道引入第一间室内的冷气，向第一间室回风。
可选地，第二间室的底部具有回风口；在门体处于关闭状态时，回风口位于第一间室内，以允许第二间室向第一间室回风。
可选地，进风段内设置有进风风机，以将冷气从进风口吸入风道；且进风口和进风风机均位于进风段的横向中央位置，以使进风风机向进风段的横向两侧均匀吹风。
可选地，出风段的横向中央位置设置有排风风机，以便向出风口排气。
可选地，门体包括：内胆，其限定出第二间室和进风段；和围挡罩，在内胆周向外侧包围罩扣内胆，以与内胆外壁共同限定出两个送风段和出风段；围挡罩顶部设置有与进风口相对的进风格栅，底部开设有出风口。
可选地，门体包括主门和副门，主门限定有第二间室和风道，副门用于开闭第二间室。
本发明的冰箱中，门体的限定的第二间室并非简单直接与箱体限定的第一间室连通，以进行不受控地冷热交换，而是特别设计了风道为第二间室供冷。由此，冰箱可通过调节风道对第二间室的冷气供应量，来调整第二间室的制冷温度，使其真正成为独立于第一间室的独立存储空间，丰富用户的选择，提升了用户体验。
进一步地，本发明的冰箱中，风道为围绕在第二间室外侧的方环状，风道处于第二间室横向两侧的送风段用于对第二间室送风。由于送风段跨越第二间室的整个高度范围，设计者可选择在送风段多个高度位置设置多个送风部，以满足第二间室各个高度位置的冷风需求，使得第二间室各处温度分布更加均匀。而且，由于每个送风部的冷气均直接来源于风道，使得送风部的覆盖范围内都是受到风道冷气的直接冷却，制冷效率更高。
进一步地，本发明的冰箱中，第二间室设置多个子间室，每个子间室匹配独立的送风部，使得各个子间室得到独立的冷气供应，使各子间室的温度 能够独立调节，形成彼此不同的存储环境。用户可根据每个子间室内存储物对温度的特殊需求单独调节该子间室的温度，使其达到最佳存储状态。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是本发明一个实施例的冰箱的原理示意图；
图2是本发明一个实施例的冰箱的另一原理示意图；
图3是本发明一个实施例中的冰箱中门体的结构示意图；
图4是图3中的主门的N-N剖视示意图；
图5是图4的A处放大图；
图6是图3中的主门的分解示意图；
图7是图6的B处放大图。
具体实施方式
下面参照图1至图7来描述本发明实施例的冰箱。其中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”、“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
图1是本发明一个实施例的冰箱的原理示意图；图2是本发明一个实施例的冰箱的另一原理示意图；图3是本发明一个实施例中的冰箱中门体20的结构示意图；图4是图3中的主门100的N-N剖视示意图；图5是图4的A处放大图。
如图1至图5所示，本发明实施例的冰箱一般性地可包括箱体10和门体20。箱体10的前侧敞开以限定出第一间室11(本发明以门体20所在侧作为冰箱的前侧，前后方向已经在图中示出)。门体20用于开闭第一间室11，且门体20限定出第二间室110。第一间室11和第二间室110均用于存放存储物。
如图4所示，门体20还限定有一围绕在第二间室110外侧的方环状风道120。风道120包括分别位于第二间室110上侧、横向两侧和下侧的进风段121、两个送风段122、123和出风段124。进风段121、两个送风段122、123和出风段124仅仅是对一个放环形的风道120各个区段的命名，风道120在整体上是完全贯通的。
风道120的各区段中，进风段121具有用于引入冷气的进风口130，送风段122、123具有用于向第二间室110输送冷气的送风部126，出风段124具有用于排出风道120内剩余冷气的出风口140。在冰箱运行时，第二间室110外部冷气经进风口130进入风道120的进风段121，然后从进风段121分为两路分别向左右方向流动，以分别进入两个送风段122、123。送风段122、123上的送风部126可受控开启以将部分冷气引入第二间室110，以对第二间室110制冷，其余未进入送风部126的气流继续向下流动进入出风段124，最终从出风段124流出风道120。如此，风道120完成了对第二间室110的冷气供应，而且不断有新鲜冷气从进风口130进入风道120，并流向各送风段122、123，以备随时供应第二间室110，使得进入第二间室110的冷气更加新鲜、温度更低。
可使前述的送风部126包括电动风门1262，以便对从送风段122、123进入第二间室110的冷气的流量进行调节。如图7，送风段122、123开设有通向第二间室110的通风口1261，电动风门1262设置在通风口1261处，且受冰箱主控板的控制，以受控地调节通风口1261的通风量(包括关闭通风口1261)。
一些现有的结构中，直接在门体后壁上设置多个通风口，使门体限定的间室直接与箱体限定的间室连通，冷气自由流通，利用箱体的间室向门体的间室进行冷气供应。但是，这种方式使得门体的间室与箱体的间室的存储环境差异不大，使得门体间室的存在意义不大。
而本发明实施例中，门体20的限定的第二间室110并非简单直接与箱体10限定的第一间室11连通，而是特别设计了风道120为第二间室110供冷。由此，冰箱可通过调节风道120对第二间室110的冷气供应量，来调整第二间室110的制冷温度，使其真正成为独立于第一间室11的独立存储空间，丰富了用户的选择，提升了用户体验。
并且，由于风道120为围绕在第二间室110外侧的方环状，风道120处 于第二间室110横向两侧的送风段122、123用于对第二间室110送风。由于送风段122、123跨越第二间室110的整个高度范围，设计者可选择在送风段122、123多个高度位置设置多个送风部126，以满足第二间室110各个高度位置的冷风需求，使得第二间室110各处温度分布更加均匀。而且，由于每个送风部126的冷气均直接来源于风道120，使得送风部126的覆盖范围内都是受到风道120冷气的直接冷却，制冷效率更高。
例如图2和图3所示，可使第二间室110分隔为多个子间室111、112、113、114，每个子间室111、112、113、114均匹配至少一个送风部126。例如图3和图4所示，可设置4个子间室111、112、113、114，子间室111、112、113、114内可设置储物盒、抽屉、搁物架等储物模块。可使每个子间室匹配两个送风段122、123上的送风部126。也就是说，使每个子间室的横向两侧都有一个或多个进风点，以充分发挥风道120具有两个送风段122、123的优势，使子间室横向两侧的冷气供应更加均衡。
本发明实施例中，由于第二间室110设置多个子间室111、112、113、114，每个子间室匹配独立的送风部126，使得各个子间室得到独立的冷气供应，使各个子间室的温度能够独立调节，形成彼此不同的存储环境。用户可根据每个子间室内存储物对温度的特殊需求单独调节该子间室的温度，使其达到最佳存储状态。
在一些实施例中，门体20配置成在自身处于关闭状态时，使进风口130和出风口140均位于第一间室11内，以允许风道120引入第一间室11内的冷气，向第一间室11回风。在一些替代性实施例中，也可使风道120的进风口130从其他冷源引入冷气，例如连接箱体10的风路，直接从冰箱的蒸发器室引入冷气，这种替代方式在此不再赘述。
冰箱可通过蒸气压缩制冷循环系统、半导体制冷系统或其他方式进行制冷。根据制冷温度的不同，冰箱内部的各间室可划分为冷藏室、冷冻室和变温室。例如冷藏室内的温度一般控制在2℃至10℃之间，优先为4℃至7℃。冷冻室内的温度范围一般控制在-22℃至-14℃。变温室可在-18℃至8℃之间调节，以实现变温效果。不同种类的物品的最佳存储温度并不相同，适宜存放的储物间室也并不相同。例如果蔬类食物适宜存放于冷藏室，而肉类食物适宜存放于冷冻室。本发明实施例的第一间室11优选为冷藏室。
第二间室110的底部可设置回风口190。在门体20处于关闭状态时，回 风口190位于第一间室11内，以允许第二间室110向第一间室11回风。回风气流进入第一间室11后，因温度较高密度较小，从下向上流动，流动过程中逐渐被第一间室11的冷气再次冷却。
在一些实施例中，可使出风段124的横向中央位置设置有排风风机400，以便向出风口140排气，以促进了风道120内的气流流动，如图4。
此外，也可使进风段121内可设置有进风风机，以将将冷气从进风口130吸入风道120，促进风道120内的气流流动。进风口130和进风风机可均位于进风段121的横向中央位置，以使进风风机向进风段121的横向两侧均匀吹风。
图6是图3中的主门100的分解示意图。
在一些实施例中，如图6所示，门体20包括内胆101和围挡罩102。内胆101限定出第二间室110和进风段121。门体20还可包括外框103，内胆101安装于外框103内。围挡罩102在内胆101周向外侧包围罩扣内胆101，以与内胆101外壁共同限定出两个送风段122、123和出风段124。围挡罩102顶部设置有与进风口130相对的进风格栅160，底部开设有出风口140。本实施例利用围挡罩102在内胆101外侧罩扣出风道120，结构非常简单实用。
在一些实施例中，如图1至图3所示，冰箱为复合门冰箱，门体20包括主门100和副门200，主门100限定有第二间室110和风道120，副门200用于开闭第二间室110。可使主门100在箱体10前侧可转动地安装于箱体10，主门100前侧敞开以限定出前述的第二间室110，使副门200在主门100前侧可转动地安装于主门100。主门100打开时，用户从第一间室11存取物品。主门100关闭，副门200打开时，用户可从第二间室110内存取物品。
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。
