在此，专利文献1所公开的冰箱具备：储藏室，其具备具有密闭结构的真空容器；冷却单元，其冷却储藏室或真空容器；压力变动装置，该压力变动装置具备减压单元，其使真空容器内的压力可变；大气压导入单元，其向真空容器内导入大气压；以及控制装置，该控制装置在将由收纳于真空容器内部的小片的集合体构成的食品冷却至规定的冻结温度的过程中的至少一部分过程中，通过所述压力变动单元使与食品接触的气体空间的压力变动。
此外，专利文献1的发明具备对真空容器进行开闭的第一开关阀和第二开关阀。更详细而言，伴随着真空泵的动作开始打开第一开关阀，对真空容器进行减压，在真空泵的动作停止后，打开第二开关阀，向真空容器导入大气(解除真空容器的气密状态)。根据该结构，能够在减压的状态下通过大气压导入单元将大气压导入或加压，对食品施加风压，对食品进行玫瑰状冻结。
然而，关于第一开关阀和第二开关阀的具体结构，专利文献1既未公开也没有启示。在此，基于避免冰箱的成本飙升等观点，要求一种具有简单结构且能够容易导入冰箱内的阀机构。但是，如前述那样，专利文献1所公开的第一开关阀和第二开关阀的结构并不具体，因此在专利文献1的发明中，不明确是否能够解决那样的 课题。
鉴于前述课题，本发明的目的在于，提供一种冰箱，其具备一种阀机构(对密闭容器进行减压时使用的阀和解除气密状态时使用的阀)，该阀机构具有简单的结构，同时能够适当地维持密闭容器的减压状态，且能够在期望的时刻解除密闭容器的气密状态。
为了解决所述课题，本发明的冰箱的特征在于，其具备：密闭容器，其包括食材，配置在冷蔵室内；真空泵，其对密闭容器内的压力进行减压；以及气密状态解除单元，其解除密闭容器的气密状态，密闭容器具备收纳食材的容器主体和堵塞容器主体的开口部的盖部，盖部具备：与容器主体内连通的第一贯通孔；能够堵塞第一贯通孔的第一阀；以及第一连通路，其具备面对第一贯通孔和第一阀的一端、以及连通盖部外并面对真空泵的另一端，伴随着真空泵的减压动作而堵塞第一贯通孔的第一阀被真空泵抽吸，从第一贯通孔离开，另一方面，伴随着真空泵的减压动作的停止，第一阀朝向第一贯通孔移动，封堵第一贯通孔。
此外，在本发明的冰箱中，其特征在于，盖部具备：与容器主体内连通的第二贯通孔；能够堵塞第二贯通孔的第二阀；以及第二连通路，其具备面对第二贯通孔和第二阀的一端、以及与盖部外连通的另一端，气密状态解除单元具备：作用部，其以能够推动第二阀的方式插入第二连通路；以及作用部进退机构，其使作用部进退，当解除密闭容器的气密状态时，堵塞第二贯通孔的第二阀因作用部的前进而被推动，打开第二贯通孔，因作用部的后退，第二阀返回到被作用部推动前的位置，从而封堵第二贯通孔。
而且，在本发明的冰箱中，其特征在于，密闭容器以能够拆装的方式设置于冷蔵室内的规定位置。
而且，本发明的冰箱的特征在于，还具备：管路，其与真空泵的进气口连接；壳体，其收纳真空泵和所述管路，并且与密闭容器对置；以及密封部，其配置在壳体与密闭容器之间，当被密闭容器按压时，密封部以朝向壳体侧凹陷的方式弹性变形，在与密闭容器对置的一侧的壳体壁面形成有壁面贯通孔，所述管路面对壁面贯通孔，密封部具备连通所述壳体的所述壁面贯通孔和所述密闭容器的所述第一连通路的密封部贯通孔。
而且，在本发明的冰箱中，其特征在于，在所述壳体壁面突出设置有收纳密封部的密封部收纳壁，密封部收纳壁沿突出方向的长度比密封部的厚度小。
根据本发明，能够在冷蔵室的冷蔵环境下对密闭容器内进行减压。其结果是能 够提高密闭容器中收纳的食材的保存性。此外，根据本发明，通过第一阀面对设置于盖部的第一连通路，且随真空泵的动作相应地动作，能够实现与容器主体内连通的第一贯通孔的开闭。即，根据本发明，根据这样简单的机构，对密闭容器进行减压，且能够适当地维持规定的阈值以下的减压状态。因此，不会导致产品的成本过度飙升。而且，根据本发明，由于具备气密状态解除单元，因此能够在期望的时刻解除密闭容器的气密状态。而且，根据本发明，能够在冷藏室内解除密闭容器的气密状态。因此，即使通过气密状态解除单元打开密闭容器，食材的气味不会泄露到冰箱外。
此外，根据本发明，利用第二阀随插入盖部的第二连通路的作用部的进退动作相应地动作，能够实现与容器主体内连通的第二贯通孔的开闭。即，根据本发明，利用这样简单的机构，能够解除减压到规定的阈值以下的密闭容器的气密状态。因此，不会导致产品的成本过度飙升。
而且，根据本发明，由于密闭容器以能够拆装的方式设置于冷蔵室内的规定位置，能够在冰箱外进行将食材收纳于密闭容器的操作。因此，能够简便地进行将食材收纳于密闭容器直到将其设置于冷蔵室内。
而且，根据本发明，在收纳真空泵的壳体与密闭容器之间配置密封部，当该密封部被密闭容器按压时，以朝向壳体侧凹陷的方式弹性变形，由此，能够可靠地防止空气从形成于密闭容器的盖部的第一连通路至与真空泵连接的管路的流路泄露。
而且，根据本发明，由于密封部收纳壁以包围密封部的方式安装，因此，从壳体的外侧侵入管路的冷气或冷凝水的路径被堵塞。其结果是，能够防止冷气或冷凝水被吸入真空泵内。此外，根据本发明，通过使密封部收纳壁沿突出方向的长度比弹性变形前的密封部的厚度小，即使以包围密封部的方式设置密封部收纳壁，也能够将密闭容器推到密封部上。其结果是，能够使密闭容器与密封部可靠地密切接触，以使得空气不泄露。

具体实施方式
以下，参照附图，详细地说明本发明的一个实施方式的冰箱1。另外，每当说明本实施方式的冰箱1，“上下”方向对应于冰箱1的高度方向，“左右”方向对应于冰箱1的宽度方向，“前后”方向对应于冰箱1的进深方向。
首先，关于本实施方式的冰箱1的整体结构，参照图1进行说明。在此，图1是冰箱1的侧视垂直截面图。如图1所示，本实施方式的冰箱1具备相当于冰箱主体的隔热箱体2。隔热箱体2具备钢板制的外壳2a、合成树脂制的内壳2b、以及填充在形成于外壳与内壳之间的间隙内的发泡聚氨酯(聚氨酯泡沫)制的隔热材料2c。
此外，隔热箱体2具备多个储藏室3、4、5。各储藏室由隔热分隔壁6a、6b分隔。本实施方式中多个储藏室从上到下依次对应于冷蔵室3、蔬菜室4、冷冻室5。但是，各储藏室的配置顺序不限于此(例如可以从上到下依次配置冷蔵室、冷冻室、蔬菜室)。
设置于隔热箱体2的各储藏室的前表面开口。以能够开闭地堵塞各开口的方式设置有隔热门。在此，例如，从冰箱的正面看，覆盖冷蔵室3的开口的隔热门的右端的上下端部能够转动地支承于隔热箱体2，以堵塞冷蔵室3的前表面开口。此外，覆盖蔬菜室4的开口的隔热门相对于隔热箱体2配置成能够沿前后方向拉出，覆盖蔬菜室4的前表面开口。同样地，覆盖冷冻室5的开口的隔热门相对于隔热箱体2配置成能够沿前后方向拉出，覆盖冷冻室5的前表面开口。
接着，参照图2至图6来说明收纳于冷蔵室3的密闭容器10和真空泵20。在此，图2是收纳密闭容器10和真空泵20的冷蔵室3的局部立体图。此外，图3是冷蔵室3中收纳的密闭容器10和真空泵20的俯视截面图(将图1所示的冷蔵室3沿A-A’线剖切而成的图)。而且，图4是图3所示的密闭容器10和真空泵20的B-B’截面图。而且，图5是图3所示的密闭容器10和真空泵20的C-C’截面图。而且，图6是收纳真空泵20的壳体21的立体图。
如图2和图3所示，本实施方式中的密闭容器10和真空泵20设置于冷蔵室3的底壁31侧。此外，在冷蔵室3的前侧配置有密闭容器10。虽没有特别限定，密闭容器10以能够拆装的状态载置于导肋32，该导肋32从冷蔵室3的底壁31朝向上方突出设置。
通过导肋32，密闭容器10被引导至规定的设置位置。因此，能够可靠地设置密 闭容器10，能够简便地连接密闭容器10与真空泵20，以使得从密闭容器10排出的空气没有泄露。
即，密闭容器10以能够从冷蔵室3出入(能够拆装)的状态收纳。通过将密闭容器10设为从冷蔵室3可进可出，预先在冰箱1的外侧将食材收纳于密闭容器10后，能够将该密闭容器10收纳于冷蔵室3。由此，能够将食材简便地收纳于密闭容器10。
本实施方式中的食材优选为在浸渍于调味料的状态下收纳于密闭容器10。但是，食材也可以以其他方式收纳于密闭容器10。食材的例子举出牛肉、猪肉、鸡肉等畜肉类、海鲜类、蔬菜类等。此外，调味料的例子举出含有盐、糖、酸化剂、香辛料、淀粉类原料、鲜味原料等的液状调味料、味增等糊状调味料等。但是，不限于此。
相对于此，在密闭容器10的后方侧配置有真空泵20。本实施方式中的真空泵20收纳于壳体21。本实施方式的情况下，壳体21与密闭容器10对置。即，密闭容器10与壳体21沿着前后方向并列设置。但是，真空泵20的位置只要能在密闭容器10内进行减压，则不限于此。此外，真空泵20也可以设置于冰箱1中的冷蔵室3以外的位置。
此外，在被密闭容器10与真空泵20夹着的区域设置有密闭容器检测传感器33，该密闭容器检测传感器33检测密闭容器10收纳到冷蔵室3内的规定位置。密闭容器检测传感器33的形态只要能够检测密闭容器10收纳到规定位置，则没有特别限定。作为密闭容器检测传感器33的示例，除了根据与密闭容器10的接触而输出检测信号的微动开关之外，还可举出磁传感器、光传感器等。
接着，如图4(a)所示，本实施方式中的密闭容器10具备：收纳食材的中空的容器主体11；覆盖容器主体11上部的开口部的中盖12；以及载置于中盖12的上盖13(存在将中盖12与上盖13合称为“盖部”的情况)。但是，盖部的形态不限于中盖12与上盖13为分体部件的盖部，它们也可以为一体。此外，也可以是除此以外的形态。
在容器主体11内收纳有浸渍于调味料的食材。此外，在中盖12形成有与容器主体11内连通的第一贯通孔121。而且，中盖12具备能够堵塞中盖12的第一贯通孔121的第一阀122。本实施方式中的第一阀122是平板状的部件(例如橡胶制的止回阀)，但只要能够堵塞第一贯通孔121则不限于此。
此外，上盖13具备包括面对第一贯通孔121和第一阀122的一端1311的第一连通路131。而且，第一连通路131包括与上盖13外(盖部外)连通且面对真空泵 20(壳体21内)的另一端1312。
另外，没有特别限定，第一连通路131的另一端1312与真空泵20的进气口22也可以经由管路24连接。本实施方式中的管路24是能够弯曲的树脂制管。但是，不限定于此。此外，如图4(b)所示，在与密闭容器10对置的一侧的壳体21的壁面(本实施方式的情况下为壳体21的前壁)211形成有壁面贯通孔241。管路24面对壁面贯通孔241(管路24的前端可以插入壁面贯通孔241，也可以不插入，而彼此对接地连接)。
在开始真空泵20中的减压动作(进气)前，第一阀122堵塞第一贯通孔121(图4(b))。相对于此，若真空泵20中的减压动作(进气)开始，则从真空泵20的进气口22吸入周围的空气。伴随于此，与壳体21连通的第一连通路131内减压，第一阀122分离(图4(c))。其结果是，第一贯通孔121打开，容器主体11内与第一连通路131连通。接着，通过真空泵20动作，容器主体11(密闭容器10)内减压。
此外，如图4及图6所示，在壳体21的壁面211与密闭容器10的盖部之间配置有接受密闭容器10的盖部的前端14的密封部25。在此，密封部25具备沿前后方向贯通的密封部贯通孔251。如图4(b)所示，通过密封部贯通孔251，管路24与密闭容器10的盖部的第一连通路131连通。通过这样的结构的密封部25，防止空气自形成于密闭容器10的盖部的第一连通路131至管路24的流路泄露。
而且，密封部25优选为若被盖部的前端14推压，则以向壳体21侧凹陷的方式弹性变形。通过设为这样的方式，能够可靠地防止空气自第一连通路131至管路24的流路泄露。本实施方式中的密封部25是发泡聚乙烯板，但不限于此。
而且，如图4及图6所示，在壳体21的壁面211突出设置有收纳密封部25的密封部收纳壁26。密封部收纳壁26是朝向密闭容器10突出的肋状的部件，并包围密封部25。
但是，若驱动真空泵20，则其工作热量使壳体21变暖。相对于此，壳体21的外侧因冷蔵室3的冷气而变冷。因此，因冷蔵室3的冷气，而在变暖的壳体21的外侧生成冷凝水。然而，在本实施方式的情况下，由于密封部收纳壁26以包围密封部25的方式安装，因此，从壳体21的外侧侵入管路24的冷气或冷凝水的路径被堵塞。其结果是，能够防止冷气或冷凝水被吸入真空泵20内。
而且，如图6所示，密封部收纳壁26沿其突出方向的长度(从与壁面211边界到密封部收纳壁26的前端)优选为比弹性变形前的密封部25的厚度(前后方向的尺寸)小。通过设置这样的结构，即使以包围密封部25的方式设置密封部收纳壁26， 也能够将密闭容器10的盖部的前端14推到密封部25上。其结果是，能够使盖部的前端14与密封部25可靠地密切接触，以使得空气不泄露。
此外，本实施方式优选为具备压力传感器。若通过压力传感器检测到容器主体11(密闭容器10)内的压力成为规定的阈值以下(约0.5气压以下)，则真空泵20的减压动作停止。其结果是，第一阀122朝向第一贯通孔121移动(因容器内外的压差，落下到第一贯通孔121)，第一贯通孔121被堵塞。
由此，容器主体11内维持减压后的压力。另外，压力传感器的形态没有特别限定，但作为例子，举出测量真空泵20的马达驱动电流的电流传感器。更详细而言，电流传感器所检测到的电流值的信号被发送到控制单元(例如，具备运算部的通用的计算机)，在控制单元中，将接收到的电流值换算成减压后的压力值。
接着，如图5(a)所示，在中盖12的与第一贯通孔121不同的位置设置有第二贯通孔123。此外，中盖12具备能够堵塞第二贯通孔123的第二阀124。在密闭容器10内被减压的情况下，对嵌入第二贯通孔123的第二阀124施加向密闭容器10的内侧拉入的力。由此，第二阀124在嵌入第二贯通孔123的状态下固定。另外，本实施方式中的第二阀124是球状的部件，但只要能够堵塞第二贯通孔123，则不限于此。
此外，上盖13具备包括面对第二贯通孔123和第二阀124的一端1321的第二连通路132。而且，第二连通路132包括与上盖13外(盖部外)连通的另一端1322。本实施方式的情况下，另一端1322与真空泵20的壳体21内连通。
而且，在壳体21内配置有齿轮齿条机构(齿条51和小齿轮52)。此外，在齿条51的前端安装有能够推动第二阀124的长针状的作用部53。作用部53插入第二连通路132，通过齿轮齿条机构而能够进退。
更详细而言，伴随着小齿轮52的旋转，齿条51向前侧滑动移动。据此，位于图5(b)的位置的作用部53前进(进入图的右侧)。由此，第二阀124由作用部53推动(图5(c))。其结果是，第二阀124与从第二贯通孔123脱落的方式移动，从而打开第二贯通孔123。
另一方面，在使作用部53后退的情况下(向图的左侧退的情况下)，使小齿轮52逆旋转。其结果是，齿条51向后侧滑动移动，作用部53后退。由此，第二阀124返回到被作用部53推动前的位置，从而堵塞第二贯通孔123。另外，只要能够使作用部53进退地动作，也可以具备齿轮齿条机构以外的机构。以下存在将使作用部53进退的机构称为“作用部进退机构”的情况。
通过该一连串动作，容器主体11(密闭容器10)的气密状态被解除。以下，存在将具备作用部进退机构(齿条51、小齿轮52)、作用部53的机构称为气密状态解除单元50的情况。另外，作为小齿轮52的驱动源的例子，举出马达(例如步进马达)、螺线管等电动致动器。但是，不限于此。
利用气密状态解除单元50解除密闭容器10的气密状态的动作在冷蔵室3的内部进行。因此，能够不将密闭容器10内的食材或调味料的气味向冰箱1的外侧泄露地解除密闭容器10的气密状态。
在本实施方式中，在减压动作时作用的机构(第一贯通孔121、第一阀122、第一连通路131)与在气密状态的解除动作时作用的机构(第二贯通孔123、第二阀124、第二连通路132)一起设置于密闭容器10的盖部。因此，能够简化密闭容器10的结构。此外，能够并排设置从真空泵20延伸的管路24和作用部53，能够实现节省空间化。
以上详细说明了本发明的实施方式。但是，前述的说明用于容易理解本发明，并非按限定本发明的主旨记载。本发明中可以包括不脱离其主旨地进行变更、改良的内容。此外，本发明中包括其等效物。
