如图1-图19所示，一种冰箱，其包括隔热的箱体；箱体限定多个用以储藏食物等物品的低温储藏间室。本实施例中，低温储藏间室分别是冷藏室、冷冻室；其中冷藏室位于上部，冷冻室位于底部。各低温储藏间室分别设有各自的箱门10。冰箱具有形成闭环的蒸发式制冷系统。鉴于这样的制冷系统在相关技术中为公知技术，在此不再赘述。
在一些实施方式中，冰箱包括设于箱门10上的真空封装装置，真空封装装置可设置于冷藏室所对应的箱门10上，亦可设于冷冻室所对应的箱门10上。本实施例中，真空封装装置设于冷藏室所对应的箱门10上。
在一些实施方式中，如图1-图5所示，箱门10包括前面板11及内壳12，且前面板11与内壳12配合限定出容置腔13；其中，箱门10的前面板11上形成有开孔110，内壳12上形成有安装口120。其中，内壳12的安装口120处设有装配座14，装配座14包括固定于内壳12上的装配板141及环绕安装口120的密封件142。
容置腔13内设有固定座2，如图6-图9所示，固定座2包括固定于前面板11上的固定板21，固定板21与前面板11上的开孔110相对应；固定板21上形成有向箱门10的内壳12一侧凹陷的收容腔22；固定板21靠下方的区域设有安装通道23，安装通道23一端与收容腔22相连通，另一端与内壳12上的安装口120相连通。其中，安装通道23与收容腔22通过连通口24相连通；且收容腔22内沿连通口24的下边沿设有支撑板25。
真空封装装置安装于固定座2上，且真空封装装置包括上支座33和下支座4，上支座33与下支座4其中之一固定连接在箱门10上；上支座33与下支座4其中之一在驱动装置15驱动下上下移动；上支座33与下支座4移动至两者对接后两者之间的空腔形成抽真空区。本公开中设置固定座于前面板11与内壳12所限定出的容置腔13内，将真空封装装置安装于固定座2上， 以将真空封装装置安装于箱门10上，以上设置方便各部件加工，且装配紧凑，连接稳固。
上支座33设于固定座2的收容腔22内，且上支座33的下端形成有第一开口腔31；下支座4通过安装通道23安装于收容腔22内的支撑板25上；下支座4的上端形成有第二开口腔41；当下支座4安装到位时(下支座4通过安装通道23安装于收容腔22内的支撑板25上)，第一开口腔31与第二开口腔41相对应，且在上支座33与下支座4移动至两者对接时，第一开口腔31与第二开口腔41共同限定出抽真空区，能够实现有效的抽真空。本实施例中，驱动装置15驱动上支座33上下移动，以与下支座4分离或对接。本实施例中，驱动装置15包括驱动电机及齿条，驱动电机的输出轴上连接有驱动齿轮，齿条与驱动齿轮相啮合，且齿条远离驱动电机的一端与上支座33固定连接，以将驱动电机的旋转运动转化为齿条的直线运动，最终驱动上支座33上下移动。
在抽真空区的靠近前面板11的一侧，设有用于在抽真空结束后对储物袋进行塑封处理的封装区，封装区内设有相对设置的隔热垫42与加热装置32；具体地，加热装置32安装于上支座33的下表面；隔热垫42则安装于下支座4的上表面。其中，储物袋为塑料材质，在加热作用下完成储物袋的真空封装。
如图10-图13所示，下支座4包括第一壳体43；其中，第一壳体43内形成有具有开口的第一容纳腔431，且其开口端位于第一壳体43靠近内壳12的一端；第一壳体43的开口端形成有连接板44，连接板44上安装有第二壳体45，第二壳体45内形成有具有开口的第二容纳腔451，且第二壳体45的开口端与连接板44相配合。其中，第一壳体43的第一容纳腔431及第二壳体45的第二容纳腔451内设有保温件，第二壳体45、保温件及下支座4上连接板44配合形成保温门7。当下支座4通过安装通道23伸入收容腔22内后，第二壳体45安装于支撑板25上，保温门7与安装口120处的密封件142相配合，以有效封堵内壳12上的安装口120。另外，第二壳体45下端设有可旋转的把手8，以方便操作者通过把手8将下支座4由箱门10上拆卸。
如图14-图15所示，上支座33的顶部设有安装座16，安装座16上安装有与抽真空区相连通的抽气装置5；抽气装置5包括抽气管51、与抽真空区通过抽气管51相连通的真空泵52。上支座33上设有连通孔33，抽气装置5的抽气管51通过上支座33上的连通孔33与第一开口腔31相连通，从而在上支座33与下支座4移动至两者对接时，使真空泵52与抽真空区相连通。
在一些实施方式中，抽气装置5的真空泵52安装于安装座16上，用于驱动上支座33上下移动的驱动装置15亦安装于安装座16。本实施例中，设置两组驱动电机、驱动齿轮及齿条，以对上支座33的相对两端同步驱动，以增加上支座33上下移动的稳定性和可靠性。真空泵52及驱动装置15均设于安装座16下部，且真空泵52的相对两侧均设有驱动装置。
另外，抽气管51上设有压力检测单元和泄压单元，压力检测单元和泄压单元均安装于安装座16上。其中，压力检测单元具体为压力传感器，用于检测抽真空区的压力；泄压单元为电动泄压阀，用于对抽真空区进行泄压。使用前，根据抽真空区的真空度设置压力传感器的设定值，需要对储物袋进行抽真空时，开启真空泵52，当压力检测单元检测到抽真空区的压力达到设定负压值时，控制真空泵52停止，真空泵52根据压力传感器的检测值开启或停止，保证了抽真空效果，在抽真空以及封装操作完成后，通过开启电动泄压阀自动控制抽真空区进行泄压，方便用户取出储物袋。
另外，安装座16靠近前面板11的一侧安装有显控单元17，前面板11的开孔110处设有操作面板18。显控单元17用于显示真空封装装置工作状态并用于控制真空封装装置启动或停止。用户根据显控单元17显示的真空封装装置的工作状态确定是否能够抽出储物袋。
操作面板18上形成有与封装区相连通的插接口19。当用户在进行真空封装时，直接从插接口19将储物袋开孔110插入并延伸至上支座33与下支座4之间。当上支座33移动至与下支座4形成密封的抽真空区后，则将储物袋的开口置于抽真空区内，且封装区内的隔热垫42抵靠在加热装置32上，以将储物袋固定于封装区内。抽真空完成后，通过封装区的加热装置32将储 物袋快速塑封，根据设定的控制，加热装置32工作满足预设的结束条件后，控制驱动装置15带动上支座33上移，用户可抽出储物袋完成储物袋的塑封。本实施例中，加热装置32包括加热丝，通过对加热丝通电升温以实现对储物袋进行封装。
以上固定座2上设置有无自锁开关6；无自锁开关6包括触发部60，其初始状态为无自锁开关6常闭；在触发部60受到外部作用时，无自锁开关6处于打开状态；在撤去外部作用时，无自锁开关6的触发部60被释放，触发部60自动恢复初始状态；即撤去外部作用时，无自锁开关6处于关闭状态。
在下支座4通过安装通道23安装到位时，触发无自锁开关6的触发部60，无自锁开关6打开，并向显控单元17传递信号，以表明下支座4安装到位；显控单元17根据接收的信号控制真空封装模块根据系统设置正常工作；
而在下支座4安装不到位时，无自锁开关6的触发部60处于初始状态，无自锁开关6关闭；以上无自锁开关6处于关闭状态表明下支座4安装不到位，此时，显控单元17控制真空封装装置无法启动抽真空工作，或同时反馈故障或报警信号以提醒用户下支座4安装不到位无法启动真空封装装置。需要说明的是，在下支座4安装不到位表现为以下两种情况，一种下支座4安装不到位表现为下支座4由箱门10上拆除，另一种下支座4安装不到位表现为下支座4安装于收容腔22内，但其未安装至第一开口腔31与第二开口腔41位置相对应的位置。
以上设置使下支座4安装到位状态与无自锁开关6打开存在一一对应关系，下支座4安装不到位状态与无自锁开关6关闭存在一一对应关系，本公开根据无自锁开关6的打开与关闭状态来判断下支座4是否安装到位。需要说明的是，无自锁开关6设置为微动开关、柱形开关、扇形开关等机械式地无自锁功能的开关。
如图6-图9所示，作为一种可实施的方式，下支座4的下端部设有触碰部46，且触碰部46设于下支座4的前端部；支撑板25前端设有缺口26，无自锁开关6设于收容腔22的前端，且无自锁开关6的触发部60穿过缺口26 向上伸出至收容腔22内。本实施例中，触碰部46设置为凸筋。
在下支座4安装于到位时，下支座4前端部的触碰部46触碰无自锁开关6，从而触动触发部60，无自锁开关6打开，向显控单元17发出信号，以表明下支座4安装到位；显控单元17控制真空封装模块根据系统设置正常工作；
在下支座4安装不到位时，下支座4与无自锁开关6相分离，触发部60处于初始状态，无自锁开关6为关闭状态，显控单元17控制真空封装装置无法启动抽真空工作，或同时反馈故障或报警信号以提醒用户下支座4安装不到位无法启动真空封装装置。本实施例中，设置于固定座2前端的无自锁开关6设置为微动开关；应当理解的是，其无自锁开关6不局限于微动开关。
如图16-图18所示，将无自锁开关6设于固定座2靠近内壳12的一端，且无自锁开关6的触发部60向远离前面板11的一侧凸出于固定座2；本实施例中，无自锁开关6设于安装通道23的上端，且无自锁开关6的触发部60凸出于安装通道23靠近内壳12一端的端口。
在下支座4安装到位时，下支座4的连接板44(即保温门7)触碰无自锁开关6，从而触动触发部60，无自锁开关6打开，向显控单元17发出信号，以表明下支座4安装到位；显控单元17控制真空封装模块根据系统设置正常工作；
在下支座4安装不到位时，下支座4(即保温门7)与无自锁开关6相分离，触发部60处于初始状态，无自锁开关6为关闭状态，显控单元17控制真空封装装置无法启动抽真空工作，或同时反馈故障或报警信号以提醒用户下支座4安装不到位无法启动真空封装装置。本实施例中，设置于固定座2靠近内壳12一端的无自锁开关6设置为柱形开关；应当理解的是，其无自锁开关6不局限于柱形开关。
在另一些实施方式中，下支座4上设有接近感应体9；在接近感应体9移动到无自锁开关6的动作距离内时，接近感应体9对无自锁开关6产生作用，无自锁开关6动作并发送接近感应体9移动至的信号。本实施例中，无自锁开关6的初始状态为关闭状态，当接近感应体9移动到无自锁开关6的 动作距离内时，无自锁开关6打开并发送接近感应体9移动到位的信号。
接近感应体9设于下支座4上，在下支座4通过安装通道23安装到位时，接近感应体9移动到无自锁开关6的动作距离内，无自锁开关6打开并向显控单元17传递信号，以表明下支座4安装到位；显控单元17根据接收的信号控制真空封装模块根据系统设置正常工作；
而在下支座4安装不到位时，接近感应体9在无自锁开关6的动作距离之外；无自锁开关6不受接近感应体9的作用，无自锁开关6处于关闭状态，表明下支座4安装不到位，此时，显控单元17控制真空封装装置无法启动抽真空工作，或同时反馈故障或报警信号以提醒用户下支座4安装不到位无法启动真空封装装置。需要说明的是，在下支座4安装不到位表现为以下两种情况，一种下支座4安装不到位表现为下支座4由箱门10上拆除，另一种下支座4安装不到位表现为下支座4安装于收容腔22内，但其未安装至第一开口腔31与第二开口腔41位置相对应的位置。
以上设置使下支座4安装到位状态与无自锁开关6打开存在一一对应关系，下支座4安装不到位状态与无自锁开关6关闭存在一一对应关系，本公开根据无自锁开关6是否打开来判断下支座4是否安装到位。需要说明的是，无自锁开关6为磁性无自锁开关或霍尔式无自锁开关或光电式无自锁开关。
如图8-图10所示，在一些实施方式中，将无自锁开关6设于固定座2靠近内壳12的一端；本实施例中，无自锁开关6设于安装通道23的上端。接近感应体9设于下支座的保温门7内，具体的，接近感应体9设于连接板44上。
在下支座4安装到位时，与下支座4固定连接的保温门7内的接近感应体9移动到无自锁开关6的动作距离内，并对无自锁开关6产生作用，无自锁开关6打开并向显控单元17发出信号，以表明下支座4安装到位；显控单元17控制真空封装模块根据系统设置正常工作；
在下支座4安装不到位时，与下支座4固定连接的保温门7内的接近感应体9在无自锁开关6的动作距离之外，接近感应体9不对无自锁开关6产 生作用，无自锁开关6处于关闭状态，显控单元17控制真空封装装置无法启动抽真空工作，或同时反馈故障或报警信号以提醒用户下支座4安装不到位无法启动真空封装装置。本实施例中，设置于固定座2靠近内壳12一端的无自锁开关6为磁性无自锁开关，下支座4上的接近感应体9为磁铁。另外，接近感应体9也为为反射板，对应的，无自锁开关6为光电式无自锁开关。
在另一些实施方式中，接近感应体9设于下支座4的下端部，且位于下支座4的前端部；支撑板25前端设有无自锁开关6。其原理同上，在此不再赘述。应当理解的是，接近感应体9不局限于设置于下支座4的端部，亦可设置于其它位置，相应的，在下支座4安装到位时，无自锁开关6在箱体上的位置与下支座4上的接近感应体9相对应即可。
如图19所示，一种真空封装方法，其具体包括以下步骤：
启动真空封装装置，判断下支座4是否安装到位；
在下支座4安装到位时，抽气装置5运行，进行真空封装；
在下支座4安装不到位时，抽气装置5不工作，并发出提示信号(反馈故障或报警信号)。
本公开设置可与箱门连接或分离的下支座，并在箱门上设置无自锁开关；下支座安装到位时触发无自锁开关打开；下支座安装不到位时，无自锁开关关闭；本公开的设置一方面能够拆卸下支座以及时清理下支座内的留滞物，以保持下支座的干净整洁，确保真空封装健康卫生；另一方面，能够获知下支座安装到位与否的情况，以在下支座安装到位的前提下启动真空封装功能，以避免下支座安装不到位所导致的真空封装功能无效。
以上所述，仅是本公开的较佳实施例而已，并非是对本公开作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例应用于其它领域，但是凡是未脱离本公开相关技术内容，依据本公开的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本公开相关技术的保护范围。
