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。

冰箱的抽屉一般可推拉地设置在储物间室内。很多抽屉都采用了助力关闭机构，在抽屉被推入储物间室一定程度后用户可放手，抽屉在弹簧的作用下自动后移直至完全关闭。
但是，现有的助力关闭机构结构都比较复杂且可靠性不高，易产生故障。
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，使抽屉能够自动关闭且可靠性高，不易产生故障。
本发明的另一目的是要在抽屉关闭时发出提示音，提示用户听到声音后可松手，使抽屉完成自动关闭过程。
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，设置在冰箱的储物间室内，其左右两侧外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；
两个支撑组件，分别固定于储物间室的左右侧壁，每个支撑组件包括：
支架，其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；
连接件，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；
弹性元件，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；
在抽屉后移关闭过程中，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：在抽屉后移关闭过程中，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，预设距离为1～3cm。
可选地，前竖直段与水平段之间为平滑过渡。
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。
可选地，抽屉的左右侧壁分别具有前后延伸的第一滑道，以及第一滑轮；每个支架内侧形成有前后延伸的第二滑道，以及第二滑轮，并配置成：在抽屉前后移动时，使第一滑轮在第二滑道上表面上滚动，使第二滑轮沿第一滑道下表面滚动以支撑第一滑道。
可选地，第一滑道的底面具有前后延伸的翻边，第二滑轮位于翻边内侧，以使第二滑轮不会因左右移动脱离第一滑道。
可选地，第一滑轮位于第一滑道后方，第二滑轮位于第二滑道前方。
可选地，弹性元件为拉簧，其前端固定于连接件的后部，后端固定于支架。
另一方面，本发明还提供了一种冰箱，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，其中两个支撑组件分别安装于储物间室的左右侧壁；抽屉可前后推拉地设置在储物间室内。
本发明的冰箱及其抽屉组件中，两个支撑组件能够实现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，用于只许通过后移抽屉，就能使前导柱重新回到下导条前边，使机构恢复正常，非常方便快捷。
进一步地，本发明的冰箱及其抽屉组件，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，使抽屉自动关闭，使用户体验非常好。

具体实施方式
本发明实施例提供了一种用于冰箱的抽屉组件。如图1至图4所示，抽屉组件包括抽屉20和两个支撑组件10。抽屉20用于可前后推拉地设置在冰箱的储物间室内，其左侧外壁201和右侧外壁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。两个支撑组件10分别固定于储物间室的左侧壁和右侧壁，每个支撑组件10包括一个主体结构，即支架100，支架100与储物间室的左侧壁/右侧壁固定。
如图1至图4所示，可使抽屉20的左右侧壁分别具有前后延伸的第一滑道230以及第一滑轮600。每个支架100内侧(靠近抽屉20的一侧)形成有前后延伸的第二滑道110以及第二滑轮700。抽屉20前后移动时，第一滑轮600在第二滑道110上表面上滚动，第二滑轮700沿第一滑道230下表面滚动，以支撑第一滑道230。优选使第一滑轮600位于第一滑道230后方，第二滑轮700位于第二滑道110前方，以加大两个滑轮的距离，使其对抽屉20的支撑更加平稳。进一步地，如图12所示，还可使第一滑道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一滑道230。
本发明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3至图5所示，每个支撑组件10包括支架100、连接件300以及弹性元件。图3至图5示意的是位于抽屉20左侧的支撑组件10。图4至图11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。
在一些实施例中，如图3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。
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4和图5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4、图5至图6、图7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6、图7至图4、图5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8、图9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10、图11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6、图7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。
本发明实施例的另一方面提供了一种冰箱1。参见图13，冰箱包括限定有储物间室3的箱体2和至少一个根据以上任意一个实施例所述的抽屉组件。其中，两个支撑组件10分别安装于储物间室的左右侧壁，抽屉20可前后推拉地设置在储物间室内。
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。
