如图4-图17为本公开一些实施例提供的真空封装装置300的一种实施方式，图4所示，所述真空封装装置300包括：下支座310，所述下支座310设有第一开口腔311；上支座320，所述上支座320设有第二开口腔321，所述上支座320在驱动装置340驱动下可向接近或远离所述下支座310的方向移动，所述上支座320向接近所述下支座310的方向移动到位后，所述第一开口腔311与所述第二开口腔321对接并密封形成抽真空区301。上述真空封装装置300通过控制驱动装置340的自动升降实现下支座310与上支座320的锁紧与解锁，实现了自动真空封装，提高了冰箱的智能化程度。
在一些实施方式中，为了提高所述抽真空区301的密封性，如图4所示，下支座310与上支座320相对表面上设置用于密封所述抽真空区301的密封部。具体地，所述下支座310在所述第一开口腔311的外周设有第一密封槽313，所述上支座320在所述第二开口腔321的外周设有第二密封槽323，所述第一密封槽313与所述第二密封槽323的位置相对且内部设有密封圈350。设置在第一密封槽313和第二密封槽323内的两个密封圈350将所述抽真空区301密封在内侧，实现了抽真空区301的可靠密封。
在一些实施例中，如图5所示，所述第一开口腔311或所述第二开口腔321内设有限位部，用于限制插接于所述抽真空区301内的储物袋的插入位置，避免储物袋的开口位置伸出所述抽真空区301；具体地，所述限位部为设置于所述第一开口腔311或所述第二开口腔321内的限位筋322，所述限位筋322的高度大于所述第一开口腔311或第二开口腔321的深度；所述限位筋322的长度略低于所述第一开口腔311或第二开口腔321的长度。用户将储物袋插入所述抽真空区301时，所述限位筋322可阻挡所述储物袋继续向内插入；其他实施方式中，该抽真空区301还可以设置到位检测装置，具体地，可以采用微波传感器或红外传感器，用于检测向所述抽真空区301插入的储物袋的有无，进而向所述控制器发出所述储物袋是否到位信号，控制器可以根据到位信号控制所述真空泵开启。通过设置到位检测装置可以自动检测所述储物袋是否到位，控制器进而自动控制所述真空泵的通断。
在一些实施例中，所述真空封装装置300还包括抽真空组件330，如图6、图7所示，所述抽真空组件330包括与所述抽真空区301通过管路335连通的真空泵331；所述管路335上还设有压力检测装置332和泄压装置333，其中，压力检测装置332具体为压力传感器，用于在检测到抽真空区301压力；所述泄压装置333具体为电动泄压阀，所述电动泄压阀打开时，对所述抽真空区301进行泄压。用户进行抽真空封装时，开启真空泵331对所述抽真空区301进行抽真空处理，当所述压力检测装置332检测到抽真空区301的压力达到设定负压值时，控制器控制所述真空泵331停止。通过设置压力传感器可以控制所述抽真空区301的真空度，真空泵331可以根据压力传感器的检测值通断，保证了抽真空效果。在抽真空以及封装操作完成后，通过开启上述电动泄压阀可以自动控制该抽真空区301进行泄压，方便用户取出储物袋。为了避免抽真空区301的异物经过所述管路335进入所述真空泵331，所述管路335上还包括过滤保护装置，其中一种实施方式中，如图8所示，所述过滤保护装置具体为串联在管路335上的过滤容器334，所述过滤容器334的上端设置入口和出口，所述入口与所述抽真空区301通过管路335连通，所述出口与所述真空泵331通过管路335连通；抽真空区301的异物通过管路335进入所述过滤容器334留存于所述过滤容器334底部，避免异物进入所述真空泵331。为了方便清理所述过滤容器334，更具体地，所述过滤容器334包括具有开口的罐体和可拆卸连接于所述罐体的上盖，所述上盖上设置所述入口和出口，清理时将所述罐体拆下进行清洁即可，避免频繁拆装管路335导致管路335密封性变差的问题。
另一种实施方式中，如图9所示，所述过滤保护装置为设置所述管路335上的过滤网336，具体地，为了方便拆装，所述过滤网336设置在所述上支座320与所述管路335连接位置的通气孔324位置，用户将上支座320移动至最高位置处后，即可从下侧对过滤网336进行拆 装或清洁操作。
所述抽真空区301与所述管路335的连接孔可以是一个，当然，为了避免单一连接孔时所述抽真空区301内异物堵塞所述连接孔导致抽真空故障，还可以通过设置两个或两个以上的连接孔分别与所述管路335连接的方式，所述管路335之间并联设置，通过三通或多通连接器后与总管连接；其中压力传感器、电子泄压阀设置在总管上。
如图4所示，所述真空封装装置300还包括位于所述抽真空区301的外侧的封装区302，所述封装区302用于在抽真空结束后对储物袋进行塑封处理，所述封装区302内设有相对设置的隔热垫360与加热装置370；具体地，所述加热装置370安装于所述上支座320下表面的凹槽内；所述隔热垫360则安装于所述上支座320下支座310上表面的凹槽内；当上支座320移动至与所述下支座310形成密封的抽真空区301后，封装区302内的隔热垫360抵靠在加热装置370上。抽真空完成后，通过封装区302的加热装置370可以将储物袋快速塑封，根据加热装置370工作设定时长后，控制驱动装置340带动上支座320上移，用户可抽出储物袋完成储物袋的塑封。
更具体地，如图10、图11所示，所述加热装置370包括加热丝371，所述加热丝371下侧设有导热板373，用于扩散所述加热丝371的加热面积使所述储物袋塑封面积增大，塑封牢固。所述加热丝371沿所述上支座320的长度方向延伸并在所述上支座320两侧向上折弯，所述加热丝371延伸至所述上支座320上侧的自由端通过一个绝缘板372固定于所述上支座320上，具体地，所述绝缘板372为绝缘材料制成，且成型为折弯板，包覆于所述加热丝371的外侧，避免加热丝371裸露在外侧。更进一步地，所述加热丝371的两个自由端分别通过弹簧375与通过接线端子374引出的两个导线连接；通过设置弹簧375可以使所述加热丝371始终处于拉紧状态，使加热丝371平整度较高，位于所述加热丝371下侧的导热板373与储物袋接触紧密；避免加热丝371不平整导致个别位置接触不实塑封不上的问题。
上述抽真空塑封装置中，所述驱动装置340可以为电动驱动装置也可以为气压驱动装置；气压驱动装置占用空间较大，因此本实施方式中，所述驱动装置340采用电动驱动装置。具体地，如图7、图12及图13所示，所述驱动装置340包括电机341以及传动机构，所述传动机构用于将所述电机的旋转运动转换为直线运动，所述传动机构的输出端与所述上支座连接。所述传动机构包括固定连接于所述电机输出轴上的第一齿轮342；与所述第一齿轮342啮合的第二齿轮343；与所述第二齿轮343固定连接的第三齿轮344，以及与所述第三齿轮344啮合的输出齿条345，其中，所述输出齿条345下侧设有销孔，所述上支座320与所述输出齿条345通过插接于所述销孔的销轴346连接。经过上述传动机构，所述电机341的转动转 换成所述上支座320的上下移动。
在一些实施方式中，如图7所示，所述上支座320与所述驱动装置340之间设有连接板347，所述连接板347与所述上支座320螺纹连接，且所述连接板347上成型有导向槽3471，所述输出齿条345的下端插接于所述导向槽3471内，所述导向槽3471与所述输出齿条345的下端分别设有长条形的销孔，所述销轴346穿设于所述导向槽3471与所述输出齿条345的所述销孔内，当所述销轴346在所述销孔的最下端时，所述输出齿条345的下端面与所述导向槽3471的槽底具有间隙，所述间隙内设有弹性体348。
如图12所示，初始位置时，所述上支座320位于最高位置；在压合阶段，如图13所示，驱动装置340带动上支座320向下运动，为了保证下支座310与上支座320紧密配合，通常以所述电机341的设定转动行程作为到位判断信号，因此，在所述输出齿条345与所述导向槽3471之间设置弹性体348可以使上支座320下移至与下支座310接触后，所述输出齿条345能够继续向下运动一段距离，使弹性体348被压缩，防止电机341堵转，对电机341起到保护作用，并能使压合力保持稳定。
在抽真空阶段，下支座310与上支座320之间形成的密闭的抽真空区301，由于气压变低，在大气压的作用下，上支座320向下运动，此时，由于长条形销孔的存在可以使所述上支座320下移时，所述输出齿条345保持位置不动，对整个驱动装置340起到保护作用。
为了精确控制所述上支座320的移动位移进而判断所述上支座320是否移动到位使所述抽真空区301形成密封空间；其中实施方式中，所述电机341为步进电机341，通过检测所述步进电机341的转动行程判断所述上支座320是否移动到位。另一种实施方式中，在所述下支座310或所述上支座320上设有微动开关；所述上支座320移动到位后通过触发所述微动开关，所述控制器根据所述微动开关的反馈信号控制所述驱动装置340停止并锁定于当前位置。所述驱动装置340可以设置为一个，所述输出齿轮位于所述上支座320的中部区域，这种情况容易导致上支座320的边缘区域与下支座310切合不够紧密导致抽真空区301漏气；因此，为了提供抽真空区301的密封性，所述驱动装置340对称地设置在所述上支座320的两侧。相应地，所述连接板347设置一个，所述连接板347设有两个所述导向槽3471；两个输出齿条345分别伸入所述导向槽3471内。
具体地，如图6、图7所示，所述驱动装置340以及所述抽真空组件330均安装于位于所述上支座320上侧的安装座305上。所述上支座320上开设有通气孔324，用于与所述抽真空组件330连通。其中，所述安装座305的一侧设有三个腔室，其包括位于中间位置的真空泵安装腔3051，以及位于左右两侧的驱动装置安装腔3052。为了保持冰箱门体200外表面 的整体美观性以及应用真空封装装置300的便利性，如图3所示，所述门体外壳210设有向内凹陷的安装腔211，所述驱动装置340与所述上支座320连接后通过螺钉连接于所述安装座305上，所述抽真空组件330与所述上支座320上的通气孔324连接后安装于所述安装座305上，形成一个组件后，整体通过穿设于所述安装座305两侧支耳上的螺钉安装于所述安装腔211内，各个零部件实现了模块化装配，各个零件不裸露在外表面，装置的整体性较好。
用户应用该真空封装装置300对食品袋进行塑封时，特别是具有粉末状的食品例如面粉等或液体等进行塑封时，在进行抽真空时粉末或液体有可能进入到抽真空区301内，最终积存于下支座310的第一开口腔311内；因此，为了方便用户清理该下支座310内的食物残渣，该下支座310相对所述门体200可拆卸安装。
其中，所述下支座310安装于所述门体200的方式不唯一，本实施例中，如图14A-图14C所示，所述下支座310可从所述门体200的内侧(即具有内胆的一侧)可拆卸地安装于所述门体200上。由于冰箱的门体200必须保证绝热性，因此，所述下支座310朝向所述储藏室100的内侧部分设置保温小门250。其中，如图14C所示，所述门体200上开设连通内外的安装孔201，所述下支座310与保温小门250从所述门体200的内侧插接于所述安装孔201上，同时实现了下支座310的拆卸清洗以及门体200的保温性能。
其中一种实施方式中，如图15所示，所述下支座310与保温小门250一体成型；如图16、图17所示，所述下支座310与保温小门250由具有开口腔结构的第一壳体251和第二壳体252以及设置在第一壳体251和第二壳体252之间绝热件形成。其中，第一壳体251与第二壳体252卡扣连接，所述第一壳体251在远离所述第二壳体252的方向设有延伸臂2511，所述下支座310形成于所述延伸臂2511上，所述第一开口腔311为形成于所述延伸臂2511上侧的开口槽，在所述开口槽的外周设有第一密封槽313。
为了进一步保证该门体200的绝热性，避免通过该安装孔201与所述保温小门250之间的缝隙漏冷，如图16、图17所示，在该保温小门250与所述门体内胆220之间设有小门门封253。具体地，所述第一壳体251在与所述门体内胆220配合的位置处设有支臂2512，所述支臂2512的尺寸大于所述安装孔201的尺寸。所述支臂2512上设有环绕所述安装孔201的安装槽，所述小门门封253安装于所述安装槽内。
具体地，为了保证该保温小门250可靠地固定于所述门体200上，在所述保温小门250与所述门体内胆220之间设有锁定装置400，所述锁定装置400用于将所述保温小门250锁定或解锁于所述门体200上。
如图14A-图14C、图16、图17所示，所述锁定装置400包括：设置在所述保温小门250 上的锁钩组件，以及设置在所述门体内胆220上的锁定槽221，所述锁钩组件包括穿设于所述保温小门250上的锁钩，所述锁钩可在第一位置和第二位置转换，所述锁钩在第一位置时可与所述锁定槽221配合实现所述保温小门250的锁定，所述锁钩在第二位置时与所述锁定槽221脱离，实现所述保温小门250的解锁。
具体地，为了提高所述锁定装置400的可靠性，所述锁定槽221与所述锁钩分别设置两个，其中，所述锁定槽221位于所述安装孔201的上下两侧。如图15-图20所示，所述锁钩组件包括上锁钩420和下锁钩410以及复位弹簧430。如图19所示，所述下锁钩410包括与下侧的所述锁定槽221配合钩挂部414，可转动地连接于所述保温小门250上的铰接部412，位于所述保温小门250下侧的拉手部411，其中，所述拉手部411与所述钩挂部414分别位于所述铰接部412的两侧。所述下锁钩410还包括与所述上锁钩420连接的下连接部413，其中所述下连接部413沿所述拉手部411上方延伸。具体地，所述下连接部413的端部成型为T形凸起4131。如图20所示，所述上锁钩420包括与上侧的所述锁定槽221配合钩挂部421，与所述下锁钩410连接的上连接部423。具体地，所述上连接部423的下端部成型为开口槽结构4231，所述T形凸起4131插入所述开口槽4231内实现所述上锁钩420与所述下锁钩410的连接。所述上锁钩420与所述保温小门250的上端面之间设置所述复位弹簧430。更具体地，所述上锁钩420上成型有连接轴422，所述复位弹簧430套设于所述连接轴422上。

初始状态，在所述复位弹簧430的弹力作用下，所述上锁钩420和下锁钩410位于所述第一位置实现所述保温小门250与所述门体内胆220的锁定；当用户用手扳动所述下锁钩410时，所述下锁钩410绕所述铰接部412转动，所述钩挂部414向下移动脱离下侧的所述锁定槽221，同时所述连接部向上推动所述上锁钩420向上移动，所述上锁钩420脱离上侧的所述锁定槽221，所述上锁钩420和下锁钩410位于所述第二位置实现所述保温小门250与所述门体内胆220的解锁。
为了保证冰箱门体200外观美观性，参照图1、图2所示，所述冰箱门体200上在所述真空封装装置300所在区域处设有吧台门260，所述吧台门260的下端与所述门体200铰接，且其可以翻转至与所述门体外壳210表面垂直的位置处；所述吧台门260的上端通过第一推 弹开关212与所述门体外壳210连接。采用吧台门260结构可以在打开吧台门260的状态下，将装有食物的储物袋放置在吧台门260上后进行真空封装处理，方便用户操作。关闭吧台门260时，保证门体200的外观美观性。
所述吧台门260内侧还包括盖设于所述安装腔外侧的操作面板270，所述操作面板270上成型有插接口271，所述插接口271的下表面与所述第一开口腔311的上表面平齐。这样，真空封装装置300则可以整体隐藏于所述操作面板270后侧。当用户在进行真空塑封时，可以直接从操作面板270的插接口271内将储物袋开口插入，并且直接延伸至所述第一开口腔311的上表面，当上支座320下移时，则可以将储物袋的开口置于所述抽真空区301内。具体地，所述操作面板270可拆卸连接于所述门体外壳210上。所述操作面板270上还设有显控装置272，所述显控装置272包括用于显示所述真空封装装置300工作状态的指示装置；以及用于控制所述真空封装装置300启动或停止的控制按钮。用户可以根据显控装置272显示的真空封装装置300工作状态确定是否可以抽出储物袋。显控装置272可以包括“抽真空塑封”按钮、“封口”按钮、“手动抽真空”按钮、“停止”按钮；其中，点击“抽真空塑封”按钮可一键实现抽真空过程及塑封过程；点击“封口”按钮可以实现单独的储物袋封口操作、点击“手动抽真空”按钮可以实现手动抽真空处理。比如，“手动抽真空”按钮可以设置为按一次自动抽几秒，然后再按一次，一直到用户认为抽真空完成为止。或者用户可以一直按压该“手动抽真空”按钮，一直按压时，会一直抽真空，当用户停止按压该“手动抽真空”按键时，会停止抽真空，从而实现用户手动抽真空操作。点击“停止”按键时，执行泄气和上支座上升的流程，当抽真空流程进行过程中用户认为此时抽真空封装装置确定出现抽真空异常的情况下，用户通过点击该“停止”按键来实现提前结束抽真空的流程。
上述真空封装装置的抽真空封装工作流程如下，该工作流程可以包括上支座下降流程、抽真空塑封流程、泄气流程和上支座上升流程。
其中，上支座320下降具体流程如图21所示，包括：
步骤101，上支座320以第一速度进行第一阶段下降。
步骤102，确定上支座320是否下降至第一预设距离，若是，转至步骤103；若否，转入步骤101。
上支座320以第一速度下降至第一预设距离至所述上支座320的密封圈与所述下支座310的密封圈接触；上支座以较高的第一速度快速向下支座310下降，使真空塑封过程用时较短。
步骤103，上支座320以第二速度进行第二阶段下降。
步骤104，上支座320是否下降到第二预设距离，若是，则转入步骤105，否则转入步骤103。其中，所述第二速度小于所述第一速度。
上支座320下降至第二预设距离时，上支座320上的密封圈与所述下支座310的密封圈的变形达到预设值，该设定变形量足以使抽真空区密封；上支座320在驱动装置的驱动下以第二速度向下支座310运动，这是缓慢下降阶段，驱动装置的速度下降，作用力增大以保证上支座320与下支座310的密封性。
当确定上支座320下降至第一预设距离时，开启抽真空塑封流程；具体流程可以如图22所示，包括：
步骤201，开启真空泵；
步骤202，确定抽真空区301的压力值是否达到第一压力值，若是，则转入步骤207，否则转入步骤203。
压力检测装置可以确定抽真空区301的压力值是否达到第一压力值，在确定达到第一压力值后，真空泵331可以停止抽真空。
步骤203，确定抽真空时间是否达到预设抽真空时间，若是，则转入步骤207，否则转入步骤204。
确定抽真空时间是否达到预设抽真空时间，当达到预设抽真空时间，真空泵331也可以停止抽真空。
步骤204，确定抽真空区301内的压力值是否达到第二压力值，其中，所述第二压力值小于所述第一压力值；若是，则转入步骤205，否则转入步骤202。
步骤205，确定预设时间后抽真空区301内压力值变化小于第三压力值，所述第三压力值小于第二压力值；若是，则转入步骤206，否则转入步骤202。
通过压力检测装置检测抽真空区331内的压力值达到第二压力值且预设时间后压力值变化小于第三压力值时，确定抽真空过程出现异常，例如压条密封不好，或进异物，封口褶皱，袋子破裂等问题，需要提前结束抽真空。
步骤206，停止抽真空，对抽真空区进行泄压，打开抽真空区301。
确定抽真空出现异常后，真空泵331就可以停止抽真空，通过泄压装置对抽真空区301进行泄压。
步骤207，停止抽真空，进行封口加热。
抽真空步骤完成后，控制真空泵停止，并控制加热丝工作，对储物袋进行热熔塑封。
步骤208，封口加热运行达到加热时间后，延时第一时间进入泄气阶段。
封口加热装置对储物袋进行加热塑封达到加热时间后，就可以在延时第一时间后，进入泄气阶段。该加热时间和第一时间可以依据经验设置。
上述泄气和上支座上升的具体流程可以如图23所示，包括：
步骤301，泄气装置进行泄气操作。通过打开泄气阀进行管路泄气。
步骤302，泄气装置确定泄气是否超过泄气时间，若是，则转入步骤303，否则转入步骤301。该泄气时间可以依据经验设置。
步骤303，驱动装置控制所述上支座320上升。
驱动装置可以驱动上上支座320以第三速度向上运动，与下支座320分开，从而打开抽真空区301。
步骤304，上支座310上升是否达到设定步数，若是，则结束，否则转入步骤301。
上支座310上升至设定步数之后，可以准备下一次抽真空封装操作。该设定步数可以为达到上抽真空区301的起始位置。
需要说明的是，上述第一速度大于第二速度，第三速度大于第二速度，第一预设距离、第二预设距离、第一速度、第二速度和第三速度可以依据经验设置，该第一预设距离和第二预设距离可以通过控制电动马达的预设行进步数实现。
