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，以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，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。

本公开提供一种冰箱。该冰箱可以为双开门、多开门、法式开门、十字开门等开门形式的冰箱。此处对冰箱的种类不做限定。
图1为根据本公开一些实施例的冰箱的立体图，如图1所示，冰箱1包括箱体2。箱体2大致呈长方体。箱体2包括门体22及用于存储食材的储藏室。储藏室的一侧开口。门体22设有储藏室的开口处，并可封闭储藏室。并且，储藏室的内部形成该冰箱1的存储空间。该箱体2的内部根据不同的使用功能可以划分为多个独立的功能空间，可以包括冷藏室、冷冻室、速冻室及解冻室等。
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。
图2为图1所示的冰箱的门体的爆炸图，图3为图2所示的门体的另一角度的爆炸图。如图2，图3所示，门体22包括外壳23、内胆24及设于外壳23与内胆24之间的绝热层。该绝热层可以为发泡材料填充而成。外壳23开设有第一安装腔221。内胆24开设有第二安装腔241，且第一安装腔221与第二安装腔241连通。
在本公开的一些实施方式中，本冰箱1还包括设于箱体2上的真空封装结构3。该真空封装结构3可以设于箱体2的门体22的内侧壁或外侧壁上、也可以设于储藏室的内侧壁或外侧壁上。为满足大多用户的使用习惯，真空封装结构3设置于箱体2的门体22的外侧壁上。
真空封装机构3通过螺钉9、膨胀螺钉等固定安装于第一安装腔221与第二安装腔241内。并且，该第一安装腔221开设于门体22的中上方，则该真 空封装结构3位于冰箱1的中部位置。用户可以直接面向该真空封装结构，对真空封装结构3的操作高度也符合人体工学设计要求。
门体22上的第一安装腔221的开口处设有封板4。封板4用于封盖第一安装腔221。封板4开设有用于插入包装袋的插入口222。插入口222与第一安装腔221连通。插入口222设于门体22上，便于用户使用，操作方便。
在本公开的一些实施方式中，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。
请参阅图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。
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。并且，第一支座31与第二支座32可以通过手动驱动，也可以通过电动或气动驱动。本实施方式的真空封装结构3包括驱动装置。该驱动装置可以控制第一支座31及\或第二支座32自动升降运动，实现自动真空封装，提高了冰箱1的自动化性能。
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。
图4为图2所示的门体的剖视图。如图4所示，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。
具体在本实施方式中，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。
第一空腔311或第二空腔321内设有止挡筋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，止挡筋314为设置于第一空腔311内，止挡筋314的高度大于第一空腔311的深度。用户将包装袋80插入抽真空腔36时，止挡筋314可阻挡包装袋继续向内插入。并且，止挡筋314与第二空腔322的底部之间存在间隙，以保持通畅过气。
在本公开的一些实施方式中，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。
具体地，第一支座31于第一空腔311的外周开设有第一密封槽，第一密封槽内设有第一密封圈312。第二支座32于第二空腔322的外周开设有第二密封槽。第二密封槽内也设有第二密封圈322。第一支座31与第二支座32之间通过第一密封圈312与第二密封圈322保持密封连接，提高抽真空腔36的密封性。
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。当用户包装袋80进行真空封装的时候，可以直接将包装袋插入到位于箱体2外侧的插入口222上，即可实施操作，操作便捷。
抽真空组件35与抽真空腔36连通，抽真空组件35用于对抽真空腔36抽真空或泄压。抽真空组件35通过安装座33固定安装于门体22的第一安装腔221内。具体的，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的固定连接。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。在本公开的一些实施方式中，根据门体22的空间布局，安装座33还可以安装于第一支座31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。
请参阅图2，安装座33用于承载抽真空组件35。抽真空组件35包括真空泵351、压力检测装置352及泄压装置353。真空泵351用于对抽真空腔36进行抽真空。压力检测装置352用于检测抽真空腔36内的压力大小。泄压装置353用于对抽真空腔36进行泄压。安装座33上分别设有用于安装真空泵351、压力检测装置352及泄压装置353的限位筋。
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。抽真空组件35通过限位筋安装于安装座33上。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。
在抽真空结束后，封装组件38用于对包装袋80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，并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，则驱动装置驱动第一支座31反向运动，使第一支座31远离第二支座32，从而使包装袋80可以从真空封装设备3上取下。
在对包装袋80进行抽真空、封装的过程中，难免会有粉尘、液体从包装袋80内被吸出或洒落，则洒落的粉尘、液体会积聚在第二支座32的第二空腔321内。图5为图4所示的门体的另一状态的剖视图，如图5所示，为方便对第二支座32进行清理，本公开实施方式的冰箱的第二支座32可拆卸设于箱体的内胆上。
第二支座32靠近内胆24一侧设有保温门34。保温门34可拆卸安装于第二安装腔241的开口处，第二支座32通过保温门34可从第二安装腔241内拆卸出。箱体2的内胆24具有保温、绝热的作用，以保证冰箱1的储藏空间保持较低的保鲜温度。由于，内胆24上开设有第二安装腔241。保温门34设有保温层340，则保温门34可以封盖住第二安装腔241的开口，以保证整个冰箱1的内胆24在第二安装腔241的位置处也能保持保温隔热。因此，保温门34可以保持内胆24的保温性能。
图6为图3所示的门体的保温门的分解图，图7为图6所示的第二支座 与保温门的爆炸图。如图6及图7所示，保温门34包括底板341及面板342。底板341与面板342相对拼接形成一盒体，该盒体内填充该保温层340，即形成保温门34。底板341与第二支座连接，面板342朝向箱体的内侧。并且，底板341与第二支座32可以为一体结构。
图8为图7所示的第二支座与保温门的另一角度的分解图，图9为图7所示的面板的另一角度的立体图。如图8及图9所示，底板341与面板342的四周边缘位置处对应设有卡扣343及卡槽344，卡扣343及卡槽344相互配合，使底板341与面板342卡合连接。在其他实施方式中，底板341与面板342也可以通过螺栓螺纹连接。

参阅图9，保温门34朝向第二安装腔241的侧面上设有多个加强筋349。加强筋349上开设有用于收容、固定该转轴346的避让槽347。该避让槽347可以保证转轴346稳定设置于保温门34上，避免转轴346发生变形或移动，降低拉手345转动的可靠性。同样，拉手345朝向第二安装腔241的侧面上设有多个加强筋3459，该加强筋3459可以增强拉手345的强度。
真空封装结构还包括锁定结构37。锁定结构37用于将保温门34锁定于内胆24上，拉手345转动以驱动锁定结构37解锁或锁定保温门34。

参阅图6，锁定结构37还包括固定座373。固定座373固定设于内胆24。且固定座373开设有拆卸口3730，拆卸口3730与第二安装腔241的开口相对，拆卸口3730与第二安装腔241相连通。固定座373为框架形状。固定座373对第二安装腔241于位于内胆24一侧的开口进行包覆，对该处的内胆24进行保护。
固定座373包括固定片3731及门封3732。固定片3731用于与内胆24固定连接。则拆卸口3730开设于固定片3731的中部。固定片3731通过螺钉与内胆24固定连接。第二卡合部372固定设于固定片3731的外侧面上，实现第二卡合部372的固定设置。
门封3732沿拆卸口3730的周缘包覆设置。门封3732可以保证保温门34与固定座373之间保持密封，避免热量从保温门34与拆卸口3730的边缘处流失。
在本实施一些方式中，第一卡合部371为卡勾。第二卡合部372为卡槽，拉手345转动带动卡勾可在第一位置和第二位置转换，卡勾在第一位置时可与卡槽配合实现保温门34的锁定定位，卡勾在第二位置时与卡槽脱离，实现保温门34的解锁、可拆卸。
在其他实施方式中，第一卡合部371也可以为卡槽，相应的，第二卡合部372为卡勾。或者，第一卡合部371还可以为卡扣、弹性锁扣等。则第二卡合部372还可以为凹槽等形式。此处对第一开合部371与第二卡合部372的具体结构并不做限定。
图15为图14所示的保温门与第二支座的组装过程图，如图15所示，卡勾设于第一卡持面3711上。卡槽设有第二卡持面3721。第一卡持面3711与第二卡持面3721相抵持，可以增大第一卡合部371与第二卡合部372的接触面积，保证第一卡合部371与第二卡合部372稳定卡持。
当第一卡持面3711与第二卡持面3721相抵持时，保温门34朝向低温储藏空间的外侧面与拉手345朝向低温储藏空间的外侧面保持齐平。当打开冰箱门体22的时候，则保温门34朝向低温储藏空间的外侧面与拉手345朝向低温储藏空间的外侧面为其外观面。因此，保温门34与拉手345的外观面保持齐平。则拉手345不会影响冰箱的内胆24的整体平面性，避免拉手345突出，影响冰箱内部的冷藏空间。
在其他实施方式中，固定座373可以省略，第二卡合部372直接固定设 于内胆24上。则第一卡合部371与第二卡合部372也可以实现卡合锁定。
图10为图8所示面板与拉手的连接状态时的剖视图，图11为图10所示面板与拉手的相对转动时的剖视图。如图10、图11所示，锁定结构37还包括弹性件374。弹性件374设于拉手345与保温门34之间，弹性件374限位于拉手345与内胆24之间。弹性件374具有一定的预压量。参阅图10，拉手345的初始位置为第一位置，则弹性件374对拉手345具有一定的压力。参阅图11，拉手345转动至第二位置，弹性件374发生弹性形变，第一卡合部371与第二卡合部372脱离，则解锁保温门34，保温门34可从内胆24上拆卸。当松开拉手345，弹性件374恢复弹性形变，拉手345复位至第一位置，锁定结构37重新锁定保温门34。
图12为图7所示的弹性件的立体图。如图12所示，弹性件374包括螺旋管3741、第一臂3742及第二臂3743。第一臂3742及第二臂3743分别位于螺旋管3741的首尾两端。转轴346从螺旋管3741穿过，与弹性件374可转动连接。第一臂3742安装于拉手345上，第二臂3743限位抵接于保温门34上，拉手345转动，第一臂3742与第二臂3743相对运动。具体地，弹性件374可以为扭簧。
图13为图7所示的拉手的另一角度的立体图。如图13所示，拉手345的两端分别设有凸耳3454，保温门34的两端对应开设有过孔348，凸耳3454穿过过孔348，使凸耳3454位于保温门34与内胆24之间。凸耳3454开设有用于安装第一臂3742的导向槽3456。参阅图10、图11，导向槽3456为狭长形，拉手345转动带动第一臂3472转动，且，第一臂3742沿导向槽3456移动。
具体地，第一臂3742设有弯折部3744，弯折部3744可滑动设于导向槽3456内。弯折部3744可以方便第一臂3472与导向槽3456连接。
参阅图14，当需要拆卸第二支座32的时候，拉动拉手345，拉手345沿转轴346转动，带动弹性件374的第一臂3742绕转轴346转动并沿导向槽3456移动，使弹性件374呈压缩状态。同时，拉手345上的第一卡合部371与第二卡合部372相分离，则锁定结构37解锁，此时，保温门34可以从门体22上拆卸下来，进而可以对第二支座32进行清洁。
图16为图14所示的保温门与第二支座的组装后的结构示意图。参阅图15、图16，当清洁完毕之后，将第二支座32及保温门34重新安装的时候，首先将第二支座32从固定座373的拆卸口3730装入到第一安装腔221内。然后压下拉手345，使拉手345的第一卡合部371转动并能够避让第二卡合部 372的阻挡，保温门34可以进入到第二安装腔241内。当第二支座32与保温门34到位之后，则松开拉手345，则锁定结构37内的弹性件374恢复弹性形变，第一臂3742绕转轴346反转并沿导向槽3456回移，使第一卡合部371与第二卡合部372恢复相对卡合抵持的锁定状态，此时，拉手345与保温门34的面板342的外观面保持齐平。
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，该真空封装结构中的第二支座32可以从门体22拆卸下来；可以方便用户清理在抽真空过程中洒落的食物残渣，用户体验好，提高了冰箱的智能化程度。
并且，第二支座32通过锁定结构37可以实现对保温门34及第二支座32的锁定及解锁。并且，第二支座32的锁定及解锁状态，通过拉手345转动来实现，操作方便，用户体验较高。
虽然已参照几个典型实施方式描述了本发明，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。由于本发明能够以多种形式具体实施而不脱离发明的精神或实质，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。
