相关申请的交叉引用
本公开要求在2020年7月1日提交中国专利局、申请号为202010627815.8、公开名称为“冰箱”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域

背景技术
冰箱是保持低温的一种器具，通过使食物或其他物品保持恒定低温冷态以避免其腐败。随着人们生活水平的日益提高，人们对食材的保鲜需求也越来越高。
针对食材保鲜存储的问题，真空保鲜技术已经应用于冰箱领域。目前，冰箱通过在箱体内设置真空抽屉，来形成一定的真空区域，则冰箱对该真空区域内的食材进行真空保鲜。但是对于上述真空保鲜方式，由于真空抽屉的空间限制，通常用户需要将所有需要真空保存的食材全部放入真空抽屉后，进行抽真空操作，使真空抽屉内处于相对真空状态。之后，当需要使用真空抽屉内某一食材的时候，需要打开真空抽屉，则破坏原真空抽屉的真空状态。如需要继续进行真空保鲜的话，则需要重复、再次对真空抽屉进行抽真空操作，造成了资源的浪费。因此，传统冰箱在使用真空抽屉进行真空保鲜的时候，真空保存效率较低，不利于真空保鲜技术的推广应用。

对于多个功能空间的排布方式，通常，冷藏室位于箱体2的上方，冷冻室位于箱体2的下方。可以理解，对于其他类型的冰箱，对于各个空间于箱体2上的分布方式，还可以为其他方式，此处对此并不做限定。
各个功能空间之间可以分别设置相互独立的门体22，以密封该功能空间。或者，多个功能空间也可以共用一个门体22，以同时密封该多个功能空间。此处对门体22与功能空间的对应情况也不做限定。

并且，门体22上的安装槽的开口处设有封板4。封板4用于封盖安装槽。封板开设有用于插入包装袋的插入口222。插入口222设于门体22上，便于用户使用，操作方便。
在一些实施方式中，封板4可以为显控板。真空封装结构3与显控板电连接。一方面，显控板4可以显示真空封装结构3的工作状态。另一方面， 通过触控或按压显控板4，也可以对真空封装结构3的工作过程进行控制。
真空封装结构3包括第一支座31、第二支座32、安装座33、抽真空组件35及封装组件38。
第一支座31与第二支座32为真空封装结构3的主要框架结构。第一支座31与第二支座32可以相向或相背运动，以完成夹持和分离包装袋80。
参阅图3，具体地，第一支座31与第二支座32相向运动，以夹持包装袋80。当真空封装结构3对包装袋80抽真空、密封封装完成之后，则第一支座31与第二支座32可以相互分离，使包装袋80可以从真空封装结构3上取下，完成真空密封封装。
对于第一支座31与第二支座32之间的运动关系，可以为：第一支座31朝向或背向第二支座32运动；或者，第二支座32朝向或背向第一支座31运动；又或者是，第一支座31与第二支座32均发生相向或相背运动。此处对第一支座31与第二支座32两者之间的运动方式不做限定，只要能够使第一支座31与第二支座32之间能够相互靠近及能够相互分离运动即可。

对于第一支座31与第二支座32的设置位置，可以根据用户的使用习惯、根据冰箱1的门体22的空间划分等确定。第一支座31与第二支座32可以为上、下相对设置于门体22上；或者，第一支座31与第二支座32还可以为左、右相对设置于门体22上；甚至，第一支座31与第二支座32均可以倾斜设置于门体22上。其中，此处对“上、下、左、右”的描述，即为冰箱1正立、竖直放置情况下，正对冰箱时的上、下、左、右等方位。
再次参阅图3，在一些实施方式中，第一支座31设于第二支座32的上方。并且，第一支座31相对于第二支座32向下运动，使第一支座31与第二支座32相互对接。第一支座31与第二支座32的上、下相对设置的方式可以更符合用户的使用习惯，第一支座31向下压持第二支座32上的包装袋80，方便用户把持包装袋80的左右两端，可以避免包装袋80内食材倾倒等。
在一些实施方式中，第一支座31与第二支座32可相对运动形成抽真空腔36。第一支座31设有第一空腔311，第二支座32设有第二空腔322。第一支座31与第二支座32的形状相适配。当第一支座31与第二支座32相向运动，相互对接的时候，第一空腔311与第二空腔322围成密封的抽真空腔36。
插入口222与抽真空腔36相连通，包装袋80可从插入口222进入抽真空腔36内。则包装袋80可以从门体22的外侧直接进入到抽真空腔36。则包装袋80的开口位于抽真空腔36内，包装袋80的内部空间通过开口与抽真空腔36连通，并形成一完整的密闭腔。
第一空腔311或第二空腔321内设有止挡部314，用于对插接于抽真空腔36内的包装袋80进行止挡，避免包装袋80的开口位置伸出抽真空腔36。具体地，止挡部314为设置于第一空腔311内，止挡部314的高度大于第一空腔311的深度。用户将包装袋插入抽真空腔36时，止挡部314可阻挡包装袋继续向内插入。并且，止挡部314与第二空腔322的底部之间存在间隙，以保持通畅过气。
在一些实施方式中，该抽真空腔36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，用于检测向抽真空腔36内是否插入的包装袋，发出包装袋是否到位信号，控制抽真空操作。
抽真空组件35与抽真空腔36相连通。抽真空组件35用于对抽真空腔进行抽真空或泄压。
参阅图4，安装座33用于承载抽真空组件35。抽真空组件35通过安装座33固定安装于门体22的安装槽221内。具体在本实施方式中，安装座33的边缘位置设有连接耳330，安装座33通过该连接耳330实现与门体22的连 接。连接耳330可以为卡扣、卡槽、螺孔等形式。
安装座33安装于第一支座31上方。在其他实施方式中，根据门体22的空间布局，安装座33还可以安装于第一支座的下方。安装座33安装于门体22上，其形状适配于门体22的形状。安装座33为板状结构，且该安装座33的安装方向与门体22的方向平行。则安装座33平行于门体22的一侧面用于安装抽真空组件。
安装座33上设有多条限位筋。安装座33可以为一体注塑成型的板状结构。则限位筋也为一体注塑成型。该安装座33的结构简单，无需额外增加固定件即可完成抽真空组件的装配，操作方便。
限位筋于安装座33上围成多个安装腔，抽真空组件35限位安装于安装腔内。安装腔可以根据具体要装配的装置设计成相应的形状结构，安装腔可以满足多种不同的待装配设备的安装需求。安装腔可以为方形、弧形等。此处对安装腔的具体形状不做限定。

在本公开一些实施方式中，真空泵351的外侧还可以包覆有缓冲套354。缓冲套354可吸收真空泵351的振动势能。缓冲套354为软质材料制作。该缓冲套354可以为橡胶套筒或硅橡胶套筒等。
真空泵351的外侧还设有外盖355。外盖从缓冲套354的外侧对真空泵351进行限位固定。该外盖355为刚性元件。缓冲套354随真空泵351振动，并限位于外盖355的内部，外盖355可以起到减振的作用。
外盖355的形状与缓冲套354的形状相适配，以完成包覆缓冲套354的外侧面。图7为图5所示的缓冲套的立体图；图8为图4所示的真空封装结构的剖视图。参阅图7及图8，具体地，缓冲套354包括用于收容于真空泵351的筒体3541。筒体3541的两侧设有用于固定连接的连接臂3542。外盖355及连接臂3542的对应位置处开设有安装孔。螺钉通过安装孔与凸柱3311上的螺孔，使外盖355、缓冲套354及真空泵351固定安装于第一安装腔331内。
并且，连接臂3542上设有弹性凸点3543。则外盖355与连接臂3542的连接位置处通过弹性凸点进行接触，该弹性凸点3543可以减小外盖355与缓冲套354之间的接触面积，可以缓冲真空泵351的振动，降低振动传递。
筒体3541的左右两侧是有支撑筋3544。支撑筋3544可以支撑外盖355。并且，支撑筋3544在筒体3541的两侧形成限位，对位于筒体3541内的真空泵351起到限位作用，保证真空泵351能够稳定收容于筒体3541内。
再次参阅图5及图6，压力检测装置352与抽真空腔36连通，压力检测装置352用于检测抽真空腔36内的压力。压力检测装置352可以为压力传感器。在对抽真空腔36进行抽真空操作之前，可以对抽真空腔36内的真空度设置压力传感器的阈值。开启真空泵351，抽真空泵351内的压力减低，当压力值达到该阈值的时候，则真空泵351停止工作，保证抽真空效果。
安装座33上设有第二限位筋332。第二限位筋332围成用于安装压力检测装置352的第二安装腔3320，第二安装腔3320与压力检测装置352相适配。
具体地，第二安装腔3320的两侧设有与压力检测装置352相卡合的卡勾3321。第二安装腔3320通过卡勾3321与压力检测装置352实现卡合固定连接，保证压力检测装置352能够稳定收容于第二安装腔3320内。
泄压装置353与抽真空腔36连通，泄压装置353用于对抽真空腔36进行泄压。泄压装置353可以为电动泄压阀。在抽真空及封装操作完成之后，通过泄压装置353可以对抽真空腔36进行泄压，方便用户取出包装袋。
安装座33上设有第三限位筋333。第三限位筋333围成用于安装泄压装 置353的第三安装腔3330，第三安装腔3330与泄压装置353相适配。具体地，第三安装腔3330内设有凸筋3331，凸筋3331用于与泄压装置353的外侧面相抵持，以使泄压装置353夹紧限位。凸筋3331的设置位置与泄压装置353的外侧面的凹陷结构相适配，使凸筋3331与凹陷相配合实现夹紧限位。
抽真空组件35还包括气路系统。该气路系统可以由气管、气阀等相互连通形成。其中，气路可以通过导管、气流通道或者一体成型于安装座33上的管路等实现。具体在本实施方式中，气路以导气管为例进行说明，其他不再赘述。
气路系统包括主气路356。主气路356与抽真空腔36连通。主气路356从第一支座31的抽真空腔36引出。
参阅图6，安装座33上设有第四限位筋334。第四限位筋334围成用于收容主气路356的第四安装腔3340。第四安装腔3340设有弧形的弯折部3341，主气路356沿弯折部3341弯折。在对主气路356进行安装的时候，只需要将主气路356内嵌于第四安装腔3340内即可实现安装，操作方便。并且，第四安装腔3340的弯折部3341可以对主气路356的延伸起到引导作用，避免主气路356过度弯折产生死弯，影响主气路356的导通效果。
具体地，第四限位筋334包括上限位筋3342及下限位筋3343。上限位筋3342与下限位筋3343形成第四安装腔3340。主气路356于第四安装腔3340，第四安装腔3340相对于主气路356存在一定的活动空间。当第一支座31进行上下往复运动的时候，会带动主气路356发生一定移动。第一支座31向下运动，则主气路356受下限位筋3343的限位作用；第一支座31向上运动，则主气路356受上限位筋3343的限位作用。因此，上述主气路356的固定方式可以使主气路356在一定范围内保持活动，并保证其导通效果。
图9为图5所示的五通阀的立体图；图10为图9所示的五通阀的剖视图。参阅图9及图10，在本公开一些实施方式中，抽真空组件35还包括连接阀。该连接阀可以为五通阀37。五通阀37包括五个接口，即第一接口371、第二接口372、第三接口373、第四接口374及第五接口375。第一接口371、 第二接口372、第三接口373、第四接口374及第五接口375之间均实现导通。并且，每个接口的外表面设有导向面376。该导向面376有助于接口与导气管实现密封连接。
其中，主气路356与五通阀37的第一接口371接通。则抽真空组件的其他气路通过五通阀37实现与主气路356的连通。五通阀37实现了多个气路的连通，简化了抽真空组件的气路系统。各个气路与五通阀37之间组装方便，便于操作。
在其他实施方式中，五通阀37还可以为其他多个三通、四通等连接阀或连接阀的组合，此处对连接阀的具体形式不做限定。
参阅图6，在一些实施方式中，安装座33上设有多条定位筋336。定位筋336围成用于安装五通阀37的定位腔3360。定位筋336上开设有卡槽3361。五通阀37可以通过卡槽3361固定于定位腔3360内。并且，与五通阀37的接口连通的气路可以通过卡槽3361进行固定卡持，该卡槽3361可以对气路进行定位。因此，该定位筋336即可以防止五通阀37脱落，又可以对气路进行定位。
可以理解，当有气路需要经过限位筋的时候，该限位筋上也可以开设有卡槽3361。卡槽3361可以对进过的气路进行固定定位，可以保证整个气路系统的位置的稳定。
参阅图5，气路系统包括抽真空气路3562。抽真空气路3562通过五通阀37的第二接口372与主气路356连通。真空泵351的进气口通过抽真空气路3562与主气路356连通。抽真空气路3562用于连通真空泵351。
图11为图5所示的真空泵的气路示意图。同时参阅图11，抽真空组件35还设有单向阀357。真空泵351与抽真空腔36连通。单向阀357的一端与真空泵351的入气口连通，另一端与抽真空腔36连通。在真空泵351抽真空的时候，单向阀357打开，可以将抽真空腔36的空气抽出，使抽真空腔36处于负压状态。
当完成抽真空操作时，真空泵351停止工作。封装组件38对包装袋80 进行封装。在对包装袋进行封装的过程中，抽真空腔36需要保持负压状态。则单向阀357可以避免从真空泵351进入的漏气，进入到抽真空腔36内，破坏抽真空腔36的负压状态。因此，上述冰箱通过单向阀357可以减少了气路系统的漏气点，使抽真空腔36保持负压状态，保证包装袋80的真空封装效果。
抽真空组件35还包括消音装置358。气路系统还包括消音气路3563。消音气路3581与真空泵351的出气口连通。消音装置358与消音气路3563连通。消音装置358为中空结构。消音装置358包括两个接口3581。其中，一个接口3581与真空泵351的出口接通。消音装置358的中空结构3582可以使整个消音装置358的内部的横截面大小发生变化，使声波能量相位发生抵消，从而实现降低噪音的效果。
参阅图5，气路系统还包括压力检测气路3564。压力检测气路3564通过五通阀37的第三接口373与主气路356连通。压力检测装置352与压力检测气路3564连通。压力检测装置352实时检测气路系统的压力大小。当压力大小达到阈值的时候，则真空泵351停止对抽真空腔36进行抽真空操作。
气路系统还包括泄压气路3565。泄压气路3565通过五通阀37的第四接口374与主气路356连通。泄压装置353与泄压气路3565连通。泄压装置353通过泄压气路3565与主气路356连通。当按成真空封装工作后，泄压气路3565用于对抽真空腔36进行泄压。
抽真空组件35还包括抽罐气路3566及设于抽罐气路3566上的抽罐接头359。抽罐接头359用于与包装罐(图未示)连接连通。抽罐气路3566通过五通阀37的第五接口375与主气路356连通，抽罐气路3566用于对包装罐进行抽真空。
抽罐接头359为常闭状态，当接入包装罐的时候，包装罐的接头与抽罐接头359对接，从而开启抽罐接头359。则抽罐接头359与包装罐连通，通过抽罐气路3566，可实现对罐类形式的包装进行真空封装。抽罐接头359可以为单向阀。当仅对包装袋进行抽真空封装的时候，则该抽罐接头359没有连 接包装罐，则该抽罐接头359处于关闭状态，对包装袋的真空封装不产生影响。
因此，上述真空封装结构不限于对包装袋形式的包装进行真空封装，还可以对包装罐式的包装进行真空封装。
在本公开一些实施方式中，驱动装置34用于驱动第一支座31朝向第二支座32运动。并且，驱动装置34为两个，两个驱动装置34分别设于第一支座31的两端，则两个驱动装置34分别于第一支座31的两端驱动连接。在第一支座31的运动过程中，两个驱动装置34可以保住第一支座31保持受力平衡的朝向第二支座32运动。并且，当驱动装置34停止运动的时候，驱动装置34对第一支座31施加均匀的压力，使第一支座31与第二支座32之间的抽真空腔36保持紧密密封。
驱动装置34也安装于安装座33上。安装座33上设有第五限位筋335。第五限位筋335围成用于安装驱动装置34的第五安装腔3350。第五安装腔3350也为两个，且两个第五安装腔3350分别设于安装座33的两侧。第五安装腔3350与驱动装置34相适配。驱动装置34包括电机。驱动装置34需要通过螺钉将其固定安装于第五安装腔3350向内，以保证驱动装置34能够稳定设置。
封装组件38用于在抽真空结束后对包装袋的封口进行封装。封装组件38安装于第一支座31内。封装组件38位于抽真空腔36的一侧。封装组件38对应包装袋的封口位置。当封装组件38完成对包装袋80的封装操作，则第一支座31与第二支座32相背运动相互分离，使包装袋80可以从真空封装设备3上取下。
本实施方式中的冰箱1通过真空封装结构3对包装袋80进行抽真空，并进行封装，从而实现对多种食材的独立、真空包装。因此，多种食材在进行真空保鲜的时候，不会产生相互影响，食材之间不会发生相互污染。并且，在取用食材的时候，可以分别取出装有相应食材的包装袋。对某一包装袋的真空状态的破坏，不会影响其他包装袋的真空状态。装有其他食材的包装袋 可以一直保持真空状态，不必发生多次抽真空的情况。因此，相对于传统的冰箱，本实施方式的冰箱的真空保鲜的空间范围不限于真空抽屉的空间大小，扩大了冰箱1的真空保鲜的范围，提高冰箱1的真空保鲜的效率。
并且，上述真空封装结构中，安装座33上设置有多个限位筋，并形成多个用于安装抽真空组件的安装腔。安装座33的结构简单，避免额外使用其他固定件对抽真空组件35进行固定。并且，在对抽真空组件35的安装操作过程中，只需要将对应的抽真空组件35安装于对应安装腔内，操作简单，便于实施。
虽然已参照几个典型实施方式描述了本公开，但应当理解，所用的术语是说明和示例性、而非限制性的术语。由于本公开能够以多种形式具体实施而不脱离公开的精神或实质，所以应当理解，上述实施方式不限于任何前述的细节，而应在随附权利要求所限定的精神和范围内广泛地解释，因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
