Description

冰箱及其抽屉组件 技术领域
本发明涉及冷藏冷冻装置，特别是涉及一种冰箱及其抽屉组件。
背景技术
冰箱的抽屉一般可推拉地设置在储物间室内，储物间室内壁设置有滑轨装置，利于抽屉前后移动。但是，用户为了方便起见，常常用较大推力关闭抽屉，使得抽屉临近关闭时，使抽屉前端壁撞击到箱体，不仅会产生较大噪声，还会损害抽屉内的物品。抽屉长期受到撞击还容易出现故障，使其使用寿命缩短。
发明内容
本发明的一个目的旨在克服现有技术的至少一个缺陷，提供一种结构新颖简单的冰箱及其抽屉组件，在抽屉临近关闭时对其后移运动进行缓冲，使其平稳关闭。
本发明的另一目的是要实现抽屉的助力自动关闭。
本发明的又一目的是要在抽屉关闭过程中发出提示音，提示用户听到声音后可松手，使抽屉完成自动后续关闭过程。
一方面，本发明提供了一种用于冰箱的抽屉组件，其包括：
抽屉，可在一前极限位置和一后极限位置之间前后推拉地设置在冰箱的储物间室内；和
左右并排设置的两个支撑组件，每个支撑组件包括支架，支架固定于储物间室内壁，且其内侧形成有前后延伸的第一滑道，其内侧后部设置有弹性舌片；
抽屉的左侧壁和右侧壁分别可前后滑动地安装在一个支撑组件的支架的第一滑道上，抽屉组件配置成：在抽屉后移临近后极限位置时，其后端后推弹性舌片使其产生弹性变形，以使弹性舌片对抽屉施加向前的弹性缓冲力。
可选地，弹性舌片沿前后方向延伸，且其后部固定于支架，前部从后向前逐渐向上倾斜翘起；在抽屉后移临近后极限位置时，其后端与弹性舌片前部下表面接触以后推弹性舌片，使弹性舌片前部上弯，以对抽屉施加弹性缓冲力。
可选地，弹性舌片的后部沿水平面延伸，前部与水平面的夹角为5～10°。
可选地，抽屉的左侧壁和右侧壁后端分别安装有第一滑轮；在抽屉前后移动时，第一滑轮在第一滑道上表面上滚动；且在抽屉后移临近后极限位置时，第一滑轮与弹性舌片前部下表面接触以后推弹性舌片。
可选地，抽屉的左侧壁和右侧壁分别形成有前后延伸的第二滑道，支架内侧前端具有第二滑轮；在抽屉前后移动时，第二滑轮沿第二滑道下表面滚动以支撑第二滑道。
可选地，支架内侧后端固定有止挡块；抽屉后移至后极限位置时，第二滑道后端撞击止挡块，从而使抽屉无法继续后移。
可选地，抽屉的左侧壁和右侧壁各自具有上导条和位于上导条下方的下导条，上导条和下导条均具有从后向前逐渐向下倾斜的底边；支架具有上滑槽和下滑槽，上滑槽前 后延伸，下滑槽具有前竖直段、从前竖直段底端向后延伸的水平段和从水平段后端向下延伸的后竖直段；且支撑组件还包括：连接件，其前后两端分别具有轴线左右延伸的前导柱和后导柱，前导柱伸入下滑槽，后导柱伸入上滑槽；和弹性元件，其对连接件施加向后的弹性预紧力；抽屉组件配置成：在抽屉处于正常打开状态时，使前导柱卡在前竖直段内，上导条和下导条位于前导柱前方；在抽屉后移过程中，上导条后移同时其底边下压前导柱，使其脱离前竖直段进入水平段，并抵在下导条前边，以在弹性预紧力作用下推动抽屉加速后移；在抽屉前移打开过程中，使下导条前推前导柱，使其重新卡入前竖直段后，使抽屉继续前移；且在抽屉处于前导柱卡在水平段后端的异常打开状态时，后移抽屉，下导条后移同时其底边下压前导柱，使其进入后竖直段以允许下导条越过前导柱，使前导柱重新处于下导条前边。
可选地，抽屉组件还配置成：在抽屉后移过程中，在前导柱脱离前竖直段时，使下导条前端位于前导柱前方预设距离处，以使前导柱脱离前竖直段后，在弹性预紧力作用下后移撞击下导条，发出抽屉关闭的提示音。
可选地，支架具有前后延伸且相互平行的内层板和外层板，内层板和外层板上各自设置有上滑槽，内层板上设置有下滑槽；连接件处于内层板和外层板之间，其后端具有向左和向右延伸的两个后导柱，两个后导柱分别进入一个上滑槽，其前端具有一个朝抽屉延伸的前导柱。
另一方面，本发明提供了一种冰箱，其包括限定有储物间室的箱体和至少一个根据以上任一项所述的抽屉组件，其中所述支撑组件的支架固定于所述储物间室内壁；所述抽屉的左右两侧壁分别可前后平移地安装在一个所述支撑组件的支架的第一滑道上。
本发明的冰箱及其抽屉组件中，每个抽屉可前后平移地安装于两个支架。抽屉后移临近后极限位置时，将推动支架后部的弹性舌片，使弹性舌片发生弹性变形，以对抽屉施加向前的弹性缓冲力。如此一来，抽屉的后移运动受到缓冲，将平稳地关闭，而不会严重撞击冰箱其他部件，避免产生较大噪声，还延长了抽屉组件的使用寿命，也不会对其中的食品造成损害。
进一步地，本发明的冰箱及其抽屉组件利用两个支撑组件实现了抽屉的助力自动关闭，结构简单，不易发生故障。并且，在抽屉处于前导柱卡在水平段后端的异常打开状态时，用于只需后移抽屉，就能使前导柱重新回到下导条前边，使机构恢复正常，无需进行专业维修，使用非常方便快捷。
进一步地，本发明的冰箱及其抽屉组件中，在抽屉关闭时，前导柱在脱离前竖直段后，能够在弹性预紧力作用下前移撞击下导条，发出提示音。用户听到该提示音后即可松手，抽屉即可自动完成后续关闭过程，用户体验非常好。

具体实施方式
本发明实施例提供了一种冰箱及其抽屉组件。图1示意了冰箱的部分结构，仅示意出一个储物间室及其内部构造。
如图1至图4所示，冰箱包括箱体30。箱体30限定有前侧敞开的储物间室，以用于储物，前后方向已在图中标出。储物间室内设置有至少一个抽屉组件。每个抽屉组件包括一个可在一前极限位置(被向前拉出至无法继续前移的位置)和一后极限位置(被向后推入至无法继续后移的位置)之间前后推拉地设置在储物间室内的抽屉20，以及左右并排设置的两个支撑组件10。每个支撑组件10包括支架100，支架100固定于储物间室的内壁，且其内侧形成有前后延伸的第一滑道110，抽屉20的左侧壁21和右侧壁22分别可前后平移地安装在一个支撑组件10的支架100的第一滑道110上。
在一些实施例中个，抽屉组件的数量可为多个，例如图1至图4所示，抽屉组件的数量为两个，且两者左右并排设置，以利于物品的分类存储。例如可一个将抽屉内部空间营造成干燥存储区，将另一抽屉的内部空间营造成湿润存储区。
如图2、图9和图10所示，左侧的抽屉组件的左侧具有一个支撑组件10，右侧的抽屉组件右侧具有一个支撑组件10。而位于左侧的抽屉组件的右边支撑组件10的支架100与位于右侧的抽屉组件的左边支撑组件10的支架100形成于一个支架基座510上，以构成一个整体的中部支撑组件50。支架基座510固定安装于储物间室的底壁。
在一些实施例中，如图2、图4、图5所示，抽屉20具有底壁205和从底壁205的四边分别向上延伸的后侧壁203、左侧壁201、右侧壁202和前端壁204，以共同限定出具有上侧开口的容纳空间。前端壁204的顶边高出左侧壁201和右侧壁202(如图5)，以利于前端壁204密封储物间室的前侧开口。储物间室内还设置有上盖板40。上盖板40固定于储物间室内壁，用于在抽屉20处于后极限位置时封盖抽屉20的上侧开口，其上表面也可用于搁物。如图2所示，上盖板40的左右两侧各具有两个安装凸起41，储物间室左右侧壁各自具有两个安装凹陷302，每个安装凸起41嵌入一个安装凹陷302内，以实现上盖板40的固定。在抽屉20处于后极限位置时，密封组件用于密封抽屉20与上盖板40之间的间隙，使抽屉20内部形成独立密封的存储空间。
如图2、图20、图21所示，密封组件包括前密封条43和后密封条42。前密封条43沿左右方向延伸地安装于上盖板40的前边。在抽屉20处于后极限位置时，前密封条43密封抵靠前端壁204的后表面。
具体地，如图20，前密封条43可包括前密封条基体431和密封部432。前密封条基体431沿左右方向延伸，以用于与上盖板40连接(例如粘贴或卡接)。密封部432连接于前密封条基体431的前侧，且为中空管状，其内形成空腔4321。密封部432用于与前端壁204的后表面接触，且被前端壁204的后表面向后挤压，发生弹性变形而利于密封。
后密封条42安装于上盖板40的下表面，包括左右延伸的后密封段4201和从后密封段4201的左右两端向前弯折的左密封段4203和右密封段4202。在抽屉20处于后极限位置时，后密封段4201密封抵靠后侧壁203顶边，左密封段4203密封抵靠左侧壁201的顶边，右密封段4202密封抵靠右侧壁202的顶边。
具体地，如图20所示示意出的后密封条的截面图，后密封条42可包括后密封条基体421和密封片422。后密封条基体421用于与上盖板40连接(例如粘贴或卡接)。密封片422从后密封条基体421的下表面向下延伸而出，其在与抽屉20的后侧壁203、左侧壁201或右侧壁202的顶边接触时，发生弹性变形而利于密封。密封片422的厚度较薄(可低于5mm)，利于其变形。例如，对于左密封段4202而言，其密封片422受到左侧壁201顶边的挤压而向左或向右弯折，以紧贴在左侧壁201的顶边。
在一些结构中，如图5和图21所示，优选使左侧壁201和右侧壁201的顶边均从前向后逐渐向下倾斜预设角度α(参考图5)，与之对应的，后密封条42的左密封段4203和右密封段4202从前向后逐渐向下倾斜。抽屉20后移直至临近关闭时，左侧壁201和右侧壁202的顶边才会接触到左密封段4203和右密封段4202，避免产生较大摩擦，使抽屉后移过程更加省力。同时，这种设计也便于抽屉向后压紧后密封条，达到更好的密封效果。
一些现有的密封结构中，可能将上述前密封条和后密封条制作成一个整体的四边形结构。但是，使用这种结构的抽屉后移时，左/右密封段与前密封条受到抽屉向后的摩擦力，相互作用易产生移位和变形，影响密封性能，还会给抽屉带来较大的摩擦阻力。本实施例中，密封组件分为前密封条43和后密封条42两部分，前密封条43用于密封抵靠抽屉20的前端壁204，在抽屉20后移过程中不会给抽屉20带来摩擦阻力。后密封条42的左密封段4203和右密封段4202与前密封条43之间无固定连接关系，在抽屉20后移过程中，即便左密封段4203和右密封段4202被抽屉20的顶部后推，但两者不会对前密 封条43的左右两端施加任何作用力，如此可避免前密封条43的左右两端受力变形移位影响密封或给抽屉后移带来较大摩擦阻力。
如图2所示，储物间室内可设置两个抽屉组件。上盖板40用于封盖两个抽屉组件的抽屉20的上侧开口。并且，密封组件的数量也为两个，两个密封组件在上盖板40上左右并排设置，以分别与两个抽屉组件的抽屉相匹配。
在一些实施例中，如图6和图7所示，支架100的内侧后部设置有弹性舌片160。抽屉组件配置成：在抽屉20后移临近后极限位置时，其后端后推弹性舌片160使其产生弹性变形，以使弹性舌片160对抽屉20施加向前的弹性缓冲力。如此一来，抽屉20的后移运动受到缓冲，将平稳地关闭，而不会严重撞击冰箱其他部件，避免产生较大噪声，还延长了抽屉组件的使用寿命，也不会对其中的食品造成损害。
例如，可使弹性舌片160沿前后方向延伸，且其后部161固定于支架100，前部162从后向前逐渐向上倾斜翘起。弹性舌片160可由PS或聚苯乙烯等材料制成，可如图7所示，使弹性舌片160的后部161沿水平面延伸，前部162与水平面的夹角为β，β的取值范围优选为5～10°，以便将其弹力限定在5～7N，既能达到缓冲效果，又不至给抽屉20的关闭带来过大的阻力。在抽屉20后移临近后极限位置时，其后端与弹性舌片160前部下表面接触以后推弹性舌片160，使弹性舌片160前部上弯，以对抽屉20施加弹性缓冲力。在一些实施例中，可使抽屉20的左侧壁201和右侧壁202后端分别安装有第一滑轮600，在抽屉20前后移动时，第一滑轮600在第一滑道110上表面上滚动。在抽屉20后移临近后极限位置时，第一滑轮600与弹性舌片160的前部162下表面接触以后推弹性舌片160。具体而言，如图7，弹性舌片160对第一滑轮600施加通过其圆心且偏向前下方的作用力F，作用力F数直向下的分力被滑道110抵消，其向后的分力向后用于缓冲抽屉的后移。
抽屉20的左侧壁201和右侧壁202分别形成有前后延伸的第二滑道230，支架100的内侧前端具有第二滑轮700。在抽屉前后移动时，第二滑轮700沿第二滑道230下表面滚动以支撑第二滑道230。。进一步地，如图19所示，还可使第二滑道230的底面具有前后延伸的翻边231，第二滑轮700位于翻边231内侧，以使第二滑轮700不会因左右移动脱离第二滑道230。通过两个滑轮和两个滑道将抽屉20平稳支撑在两个支架100上，且前后推动非常省力。
在一些替代性实施例中，也可使抽屉20的滑道与支架100的滑道之间采用滑动摩擦连接以省略滑轮，或者将两个滑轮均设置在抽屉20上，或者将两个滑轮均设置在支架100上，具体结构在此不再赘述。
如图6所示，支撑组件的支架内侧(靠近抽屉的一侧)后端固定有止挡块170，其可由橡胶材料制成。抽屉20后移至后极限位置时，其后端端撞击止挡块170，从而使抽屉20无法继续后移，以限定出抽屉20的最大后移位置。
下面通过图4至图19介绍支撑组件的一种优选结构形式。如图4和图5所示，抽屉20的左侧壁201和右侧壁202上各自具有上导条210和下导条220，下导条220位于上导条210下方。上导条210和下导条220均具有从后向前逐渐向下倾斜的底边。
每个支撑组件10包括支架100、连接件300以及弹性元件。图6和图8示意的是位于抽屉20左侧的支撑组件10。图9、图10示意了中部支撑组件50。图11至图18中， 上导条210和下导条220均以虚线表示。
支架100具有上滑槽150和下滑槽140。上滑槽150沿前后方向延伸。下滑槽140为三段结构，其包括前竖直段141、从前竖直段141的底端向后延伸的水平段142以及从水平段142的后端向下延伸的后竖直段143。前竖直段141与水平段142之间优选为平滑过渡。
连接件300的前后两端分别具有轴线左右延伸的前导柱310和后导柱320。前导柱310伸入下滑槽140，并可沿下滑槽140的延伸方向滑动。后导柱320伸入上滑槽150，并可沿上滑槽150的延伸方向滑动。可以理解的是，因下滑槽140的形状不规则，在连接件300前后滑动时，还会产生以后导柱320的轴线为轴的转动。
弹性元件配置成对连接件300施加向后的弹性预紧力。弹性元件具体可为拉簧500，拉簧500的前端固定于连接件300的后部，后端固定于支架100。
下面介绍抽屉20的开关过程：
(1)抽屉20处于正常打开状态，如图11和图12所示。此时，连接件300受到向后的弹性预紧力，使前导柱310卡在前竖直段141内。上导条210和下导条220位于前导柱310前方。
(2)关闭抽屉20过程，即由图11、图12至图13、图14的过程。此过程中，用户先向后推动抽屉20，上导条210随之后移，其底边将接触到前导柱310。因上导条210的底边是倾斜延伸的，其在向后移动过程的同时，将向下压前导柱310，使前导柱310在前竖直段141内下移直至脱离前竖直段141，进入水平段142。前导柱310进入水平段142的同时，将在弹性预紧力的作用下后移，以恰好抵在下导条220的前边，然后在弹性预紧力作用下沿着水平段142推动下导条220加速后移，即推动抽屉20加速后移。直至抽屉20完全关闭，此时前导柱310恰好位于水平段142的后端。
优选地，在抽屉20后移关闭过程中，在前导柱310脱离前竖直段141时，使下导条220前端位于前导柱310前方预设距离(如1～3cm)处(而非恰好接触下导条220)，以使前导柱310脱离前竖直段141后，在弹性预紧力作用下加速后移撞击下导条220，发出提示音，提示用户抽屉关闭。用户听到该提示音后即可松手，使抽屉20自动关闭，使用户体验非常好。
(3)正常打开抽屉20的过程：即由图13、图14至图11、图12的过程。此过程中，用户向前拉动抽屉20，下导条220克服弹性预紧力推动前导柱310沿着水平段142前移，直至水平段142最前端时，前导柱310沿着水平段142与前竖直段141的交界处逐渐上移进入前竖直段141，以重新卡入前竖直段141。此时，前导柱310已脱离下导条220，使抽屉20得以继续前移，打开至用户需要的程度。
(4)在一些异常情况下，抽屉20处于异常打开状态。如图15、图16所示，抽屉20处于前导柱310在水平段142后端，而上导条210和下导条220位于前导柱310前方，此时机构已经失效。用户需向后移动抽屉20，使下导条220后移至与前导柱310接触的位置，在下导条220后移同时其底边下压前导柱310，使前导柱310进入后竖直段143，以允许下导条220越过前导柱310(如图17、图18所示的状态)，然后连接件300在弹性预紧力作用下转动，使前导柱310上移以重新处于下导条220前边，回到图13、图14所示的状态。使抽屉20重新处于正常关闭状态，以便用户之后完成正常打开过程。
在一些实施例中，如图8所示，支架100上具有前后延伸且相互平行的内层板120和外层板130，内层板120更加靠近抽屉20。内层板120上设置有前述的上滑槽150和下滑槽140。外层板130上设置有上滑槽150，内层板120的上滑槽150和外层板130的上滑槽150位置相对。连接件300处于内层板120和外层板130之间，其后端具有向左和向右延伸的两个后导柱320，两个后导柱320分别进入一个上滑槽150，其前端具有一个朝抽屉20延伸的前导柱310，前导柱310穿过下滑槽140，突出支架100表面，以便与上导条210和下导条220接触。
如前所述，对于设置有两个抽屉组件的实施例而言，其位于左侧的抽屉组件的右边支撑组件的支架与位于右侧的抽屉组件的左边支撑组件的支架形成于一个支架基座510上，以构成一个整体的中部支撑组件50。中部支撑组件50的支架底座510上的两个支架100的内层板120形成于支架底座510，且该两个支架100的外层板130为一体成型的整体件且可拆卸地位于两个内层板120之间。将两个外层板130与支架底座510分离设置是为了方便设计模具。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
