定义冰箱1使用时面向用户的一侧为前侧，与之相反的一侧为后侧。
在一些实施例中，参照图1和图2，冰箱1包括：箱体10，冷空气供应装置20以及门体30。箱体10包括储藏室，冷空气供应装置20被配置为冷却储藏室；门体30被配置为打开和关闭储藏室。
冷空气供应装置20通过与箱体10的外部进行热交换来冷却储藏室。如图2所示，冷空气供应装置20包括压缩机21、冷凝器22、膨胀装置23和蒸发器24，并使制冷剂以压缩机21、冷凝器22、膨胀装置23、蒸发器24、压缩机21的顺序循环来冷却储藏室。
例如，蒸发器24可以设置为与储藏室的外壁接触，以直接冷却储藏室。 在一些实施例中，冷空气供应装置20还可以包括循环风扇，以通过蒸发器24和所述循环风扇来循环储藏室中的空气。
箱体10包括沿高度方向设在箱体10中部位置处的横向分隔板11，横向分隔板11沿图1中的左右方向延伸。横向分隔板11的大致位置参照图1中的虚线框所示，高度方向参照图1中的上下方向。储藏室被横向分隔板11分隔成上部储藏室21和下部储藏室22。上部储藏室21用作以冷藏模式储藏食物的冷藏室，下部储藏室22用作以冷冻模式储藏食物的冷冻室。
门体30可枢转地与箱体10相连，以旋转打开或者关闭储藏室。例如，门体30可以被铰接在箱体10的前端。图1中示出了四个门体30。
此外，冰箱1还可以包括真空容器100，通过在真空容器100内形成部分真空，可以延长食物的贮藏期。真空容器100与储藏室可以采用可拆卸或者固定连接的方式相连。在一些实施例中，真空容器100安装在储藏室中，使得真空容器100可以从储藏室取出。在一些实施例中，真空容器100也可以固定地安装在储藏室中。
参照图3，真空容器100包括壳体110和抽屉120。壳体110限定真空容器100的外观，壳体110位于储藏室中。壳体110内限定有收纳空间，所述收纳空间被配置为储存待储存物品，且壳体110的朝向前的一端(例如朝向用户的一端)包括开口。抽屉120被从所述开口处插入或者抽出所述收纳空间，抽屉120完全插入所述收纳空间时对壳体110进行密封。
冰箱1还包括负压器130，负压器130被配置为在真空容器100中产生负压力(过真空)。例如，负压器130可以是真空泵等。在一些实施例中，负压器130可以安装在壳体110的外壁上，或者负压器130安装在储藏室的壁上。
在一些实施例中，负压器130通过抽气管190与真空容器100连通。壳体110包括与所述收纳空间连通的排气口111(参照图3)，抽气管190连接到排气口111处。例如，排气口111设于壳体110的外壁。当抽屉120插入所述收纳空间以使真空容器100处于密封状态时，负压器130可以将真空容器100中的空气抽出，以降低真空容器100内的压力。
由于不同类食材所要求的储藏环境不一样，真空容器100通常只能存放当前真空程度下的对应食材，而不能将不同类的食材放在同一个真空容器100中。为此，本公开一些实施例中的冰箱1包括N个(N为大于2的整数)真空容器100，例如，包括两个、三个、四个或更多个真空容器100。每个真空容器100被配置为储存一类食材，例如，N＝2时(即，冰箱1包括两个真空 容器时)，一个真空容器100可以用来储存果蔬类食材，另一个真空容器100可以用来储存肉类食材，这样，就解决了多种类型食材的真空存放问题。
为描述方便，以下以N＝2为例详细介绍本公开的一些实施例。
两个真空容器100在储藏室中的布置方式可以包括多种。参照图4和图5，两个真空容器100分别为第一真空容器101和第二真空容器102。在一些实施例中，第一真空容器101和第二真空容器102在储藏室内横向(即冰箱1的左右方向)并排放置。在一些实施例中，两个真空容器100还可以在储藏室内竖向(即冰箱1的上下方向)并列放置。
在一些实施例中，第一真空容器101和第二真空容器102均设置在冰箱1的上部储藏室21内。例如，图1中示出了第一真空容器101和第二真空容器102横向并排放置在上部储藏室21内。或者，第一真空容器101和第二真空容器102均设置在下部储藏室22。由此，通过将两个真空容器100设在同一个储藏室内，管路系统比较集中，可以减小管路的长度布设。
在一些实施例中，第一真空容器101和第二真空容器102中的一个设置在上部储藏室21，且第一真空容器101和第二真空容器102中的另一个设置在下部储藏室22。由此，通过将两个真空容器100分别设在上部储藏室21和下部储藏室22，可以方便用户将果蔬类食材放置在上部的真空容器100内储存，将肉类食材放置在下部的真空容器100内储存，与冰箱普通功能储存食物的分区保持一致，有利于用户对冰箱食材的分类储存。
冰箱1还可以包括电子气阀150，电子气阀150与负压器130连接，电子气阀150可以安装在壳体110的外壁上，或者安装在储藏室的壁上。在一些实施例中，电子气阀150还通过多个通气管分别与多个真空容器100连通。所述多个通气管包括第一通气管141和第二通气管142。
结合图4和图5，负压器130通过抽气管190与电子气阀150连通。第一真空容器101包括第一排气口112，第一通气管141通过第一排气口112将第一真空容器101和电子气阀150连接；第二真空容器102包括第二排气口113，第二通气管142通过第二排气口113将第二真空容器102和电子气阀150连接。第一排气口112、第一通气管141、第二排气口113、第二通气管142以及抽气管190形成真空容器100的气路系统。
在一些实施例中，第一真空容器101和第二真空容器102并联在气路系统中。由此，可以对两个真空容器100的气路通断进行联动控制，使得用户可以根据使用需要控制两个真空容器100的真空程度，从而在两个真空容器100之间任意更换储藏食材，提高了用户的使用体验。
负压器130停止工作时，气路系统使真空容器100形成密闭空间，防止气体进入真空容器100。当负压器130进行抽气工作时，根据电子气阀150的档位状态，对相应的真空容器100进行抽气并将气体排出真空容器100。
电子气阀150可以选择性使负压器130与第一真空容器101和第二真空容器102中的至少一个连通。例如，电子气阀150可以实现负压器130仅与第一真空容器101连通，负压器130仅与第二真空容器102连通，负压器130与第一真空容器101以及第二真空容器102均连通。
因此，冰箱1通过电子气阀150的档位状态可使两个真空容器100根据使用需要在真空与肉类、真空与果蔬、非真空与肉类、非真空与果蔬四种储藏工况中各自选择。通过电子气阀150进行联动，使得两个真空容器100可以在肉类储藏和果蔬储藏之间按照用户的使用需要切换，满足用户的不同储藏需求。
这样，本公开一些实施例的冰箱，通过一个电子气阀150可以实现负压器130与两个真空容器100之间的联动控制、四种工况的选择，具有管路系统结构简单、功能多样的优点。
在一些实施例中，参照图6至图8，电子气阀150包括：阀外壳151、封堵件160和161、以及驱动装置，所述驱动装置与所述封堵件160和161相连。
阀外壳151大致形成电子气阀150的主体外观，阀外壳151包括在阀外壳151内部连通的抽气通道154和支通道156和157。
参照图6并结合图5，支通道156和157具有位于阀外壳151内部的内端和延伸至阀外壳151外部的外端，所述内端参照图6中的下端，所述外端参照图6中的上端。支通道156和157的外端与对应的通气管141和142连接，通气管141和142与对应的真空容器101和102相连；抽气通道154通过抽气管190与负压器130相连，例如，抽气通道154的外端154B与抽气管190连接，抽气管190与负压器130相连。通过使电子气阀150内部的支通道156和157和抽气通道154的内端154A连通，实现了负压器130和真空容器101和102的连通，从而可以将真空容器101和102抽真空。
支通道包括第一支通道156和第二支通道157，第一通气管141连接至第一支通道156的外端156B，第二通气管142连接至第二支通道157的外端157B。
在一些实施例中，阀外壳151包括主干腔158，主干腔158位于阀壳体151的一端，抽气通道154和支通道156和157位于阀壳体151的另一端；抽气通道154通过主干腔158和支通道156和157连通。例如，在图6中主干 腔158位于阀壳体151的下端，抽气通道154和支通道156和157位于阀壳体151的上端，这样，抽气通道154和支通道156和157的布局比较集中，使得通气管141和142和抽气管190在电子气阀150上的连接位置比较集中，避免了管路分散连接占据空间的问题，有利于减小电子气阀150的体积，节省安装空间，简化管路的布设。
封堵件160和161设于主干腔158内，封堵件160和161均在第一位置和第二位置之间可转换。在所述第一位置封堵件160和161封堵对应的支通道156和157的内端，以使抽气通道154和支通道156和157断开，在所述第二位置封堵件160和161打开支通道156和157的内端，以使抽气通道154和支通道156和157连通。
在一些实施例中，封堵件160和161可滑动地在所述第一位置和所述第二位置之间转换。
参照图6至图8，封堵件包括第一封堵件160和第二封堵件161，第一封堵件160被配置为打开或封堵第一支通道156的内端156A，从而可以将第一支通道156打开或者封堵；第二封堵件161被配置为打开或封堵第二支通道157的内端157A，从而可以将第二支通道157打开或者封堵。
当第一封堵件160向靠近第一支通道156的内端156A的方向(参照图6中的M方向)滑动至所述第一位置时，第一封堵件160封堵第一支通道156的内端156A，从而将抽气通道154和第一支通道156断开(参照图7)。当第一封堵件160向远离第一支通道156的内端156A的方向(参照图6中的N方向)滑动至所述第二位置时，第一封堵件160打开第一支通道156的内端156A，从而使抽气通道154和第一支通道156连通(参照图6)。第二封堵件161对第二支通道157封堵和打开的原理与第一封堵件160类似，此处不再赘述。
在一些实施例中，参照图6，每个封堵件包括滑杆170和复位件180(例如复位弹簧等)，驱动装置驱动滑杆170滑动，复位件180维持滑杆170在不受外力的情况下复位。
主干腔158包括滑轨159，滑轨159固定设置，滑杆170相对滑轨159可滑动。在滑动方向上，滑杆170的长度大于滑轨159的长度，所述滑动方向参照图6中所示的MN方向。滑杆170包括第一挡部171和第二挡部172，第一挡部171和第二挡部172分别位于滑杆170沿长度方向的两端。第一挡部171靠近驱动装置，第一挡部171位于图6中左侧的滑杆170的N端，第二挡部172靠近支通道，第二挡部172位于图6中左侧的滑杆170的M端。
复位件180套设在滑杆170的外侧，且位于滑轨159的远离第二挡部172的一端和第一挡部171之间。例如，图6中左侧的复位件180位于滑轨159的N端与第一挡部171之间。
当驱动装置驱动滑杆170运动时，滑杆170压缩复位件180并朝向靠近支通道的方向(参照图6中的M方向)滑动，以通过第二挡部172将支通道堵住，此时封堵件处于所述第一位置。当驱动装置的驱动力减小甚至消失时，滑杆170在复位件180的作用下复位并打开支通道，此时封堵件处于所述第二位置。当第二挡部172的远离支通道的一侧与滑轨159的远离第一挡部171的一端相抵时，滑杆170停止滑动。例如，当图6中左侧的第二挡部172的N侧与滑轨159的M端相抵时，滑杆170停止滑动。
根据本公开的一些实施例，封堵件的滑动主要通过机械结构实现，相对于电控结构，故障率低，可靠性高。
在一些实施例中，第一挡部171和第二挡部172中的至少一个形成为半球形。参照图6至图8，第一挡部171大致呈半球形，第一挡部171的平面171B与滑杆170相连，第一挡部171的球面171A与驱动装置接触，这样可以减小第一挡部171和驱动装置的接触面积，减少长期使用过程中的接触磨损。
在所述第一位置，封堵件与支通道密封连接。在一些实施例中，第二挡部172大致呈半球形，第二挡部172的平面172B与滑杆170相连，第二挡部172的球面172B与支通道的内端相对，这样可以保证第二挡部172封堵支通道时的密封性。
在一些实施例中，支通道的内端和第二挡部172中的至少一个包括密封件，所述密封件为诸如橡胶件，这样可以进一步提高滑杆170在封堵支通道时的密封性。
驱动装置设于主干腔158内，驱动装置被配置为驱动封堵件在所述第一位置和所述第二位置之间滑动。参照图6至图8，驱动装置包括电机和凸轮191，电机被配置为输出动力，电机与凸轮191相连以驱动凸轮191旋转。
凸轮191的周部包括向外凸出的凸部192，当凸部192与滑杆170相抵时(参照图6和图7)，可以使滑杆170朝向靠近支通道的方向滑动，例如图7中左侧的滑杆170朝向M方向滑动；当凸部192与滑杆170相错时，滑杆170所受到的驱动力减小或消失，复位件180复位并带动滑杆170反方向滑动，例如图6中左侧的滑杆170朝向N方向滑动。
参照图6，当抽真空的目标为第一真空容器101，电机输入的档位为第一 支通道156时，凸部192在对应第二封堵件161的位置处停止并推动滑杆170对第二支通道157进行封堵，隔断第二支通道157的气体流通。此时，第一封堵件160与凸部192相错、未受凸轮191的作用，复位件180的复位弹力使滑杆170复位(例如将滑杆170固定在与第一支通道156分开的位置)。该状态下，第一支通道156与抽气通道154连通(如图6中虚线所示，箭头指向代表抽气方向)，负压器130通过第一支通道156和抽气通道154对第一真空容器101进行抽气形成负压。
参照图7，当抽真空的目标是第二真空容器102，电机输入档位为第二支通道157时，凸部192在对应第一封堵件160的位置处停止并推动滑杆170对第一支通道156进行封堵，隔断第一支通道156的气体流通。此时，第二封堵件161与凸部192相错、未受凸轮191的作用，复位件180的复位弹力使滑杆170复位(例如将滑杆170固定在与第二支通道157分开的位置)。该状态下，第二支通道157与抽气通道154连通(如图7中虚线所示)，负压器130通过第二支通道157和抽气通道154对第二真空容器102进行抽气形成负压。
参照图8，当抽真空的目标为第一真空容器101和第二真空容器102，电机190输入档位为全通时，凸部192均与第一封堵件160、第二封堵件161相错，两个滑杆170此时均未受到凸轮191的作用，复位件180的复位弹力将滑杆170固定在与第一支通道156、第二支通道157分开的位置。该状态下，第一支通道156和第二支通道157均与抽气通道154连通(如图8中虚线所示)，负压器130通过第一支通道156和抽气通道154对第一真空容器101进行抽气形成负压，负压器130通过第二支通道157和抽气通道154对第二真空容器102进行抽气形成负压。
根据本公开的一些实施例，通过控制电机的旋转角度可以改变凸轮191与封堵件的相对位置关系，从而控制目标支通道与抽气通道154的连通和关闭，具有结构简单的优点。
本领域技术人员可以理解，对于真空容器100的数量N＞2的实施例可以在真空容器100的数量N＝2的实施例的基础上进行类推：
冰箱1具有N个真空容器100，N个真空容器100各通过一条通气管与电子气阀150连通。电子气阀150包括N条支通道，以及对应N条支通道的N个封堵件；凸轮191包括N-1个凸部192。
当N-1个凸部192分别对应前N-1个封堵件时，第N个封堵件不受凸轮191的作用，第N个支通道为通路，负压器130可经第N个支通道和抽气通 道154对第N个真空容器进行抽气形成负压。当凸部192均与N个封堵件相错时，电子气阀150内N个支通道均为通路，负压器130可经电子气阀150分别对N个真空容器进行抽气形成负压。
在一些实施例中，电子气阀150包括N个驱动装置，以分别对应驱动相应的一个封堵件，对应每一个支通道单独由一个驱动装置控制，同样可以实现对相应真空容器100抽真空的目的。
根据本公开的一些实施例，通过设置多个真空容器100，从而可以实现多种不同类型食材的真空保鲜储存，避免了相关技术的冰箱内只有单个真空容器100无法分别真空储存不同类型食材的问题。通过电子气阀150将多个真空容器100并联在一个气路系统中，可以对多个真空容器100的气路通断进行联动控制，使得用户可以根据使用需要在真空容器100间任意更换储藏食材，提高了用户的使用体验。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
本领域技术人员应当理解，本公开中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与一些实施例公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
