Description

冰箱 技术领域
本发明涉及冷藏冷冻装置，特别是涉及一种冰箱。
背景技术
大容量的冰箱通常采用左右对开门结构，其中一个门体上安装一个密封用的竖梁，以防止冷气从两个门体之间的间隙外泄，在该门体打开时，竖梁处于近似垂直于门体的状态，即折叠状态。该门体关闭过程中，竖梁将沿一竖直轴线转动至近似平行于门体的状态，即展开状态，以密封该门体与另一门体之间的间隙。一般地，储物间室顶壁设置有开口朝下的导向槽，在竖梁顶部和/或底部设置向上凸伸的导向件，在开门或关门过程中，导向件将沿导向槽的延伸轨迹运动，以引导竖梁正确转动。
但是，上述方案常常因为导向件与导向槽的摩擦等因素导致竖梁转动卡顿、晃动，导致竖梁转动不畅，使用户关门时的体验较差。而且，由于设置导向件和导向槽，使得竖梁顶部/底部与储物间室顶壁/底壁之间的密封性能也较差。此外，导向槽和导向件的设置也影响了冰箱的美观。
发明内容
本发明的目的旨在至少克服现有技术的上述缺陷之一，提供一种无需设置导向件和导向槽，也能使竖梁在开关门过程中能自动转动的冰箱。
本发明的目的是要提升竖梁转动顺畅度，避免竖梁转动卡顿，提升竖梁与储物间室内壁的密封性能。
特别地，本发明提供了一种冰箱，其包括前侧敞开的箱体、以对开方式可转动地设置在箱体前侧的第一门体和第二门体、可绕第一竖直轴线转动地安装于第一门体打开端的竖梁、以及至少一个驱动机构，驱动机构包括：
伸缩件，可沿第一门体的厚度方向伸缩地安装于第一门体，以处于使其后端凸伸出第一门体内侧表面的伸出位置，或处于由伸出位置朝第一门体内部缩进预设距离的缩进位置；
弹性件，配置成对伸缩件施加促使其朝伸出位置移动的弹力；
转动件，可绕第二竖直轴线转动地安装于第一门体，且可绕第三竖直轴线转动地安装于伸缩件，转动件上形成有滑道；和
滑柱，直接或间接固定于竖梁且可沿滑道滑动；冰箱配置成：
在第一门体处于打开状态时，使伸缩件处于伸出位置，使竖梁处于贴靠在第一门体内侧的折叠状态；且
在第一门体关闭过程中，使伸缩件被箱体阻挡而向缩进位置移动，带动转动件绕第二竖直轴线转动，使滑道推动滑柱以带动竖梁转动至展开状态，以便密封第一门体和第二门体之间的间隙。
可选地，驱动机构还包括连杆，连杆与竖梁固定连接且朝远离竖梁的方向延伸出，滑柱安装于连杆的远离竖梁的一端。
可选地，连杆临近竖梁的端部可转动地安装于第一门体，以便竖梁绕第一竖直轴线转动。
可选地，伸缩件、转动件以及连杆在竖直方向错位排列。
可选地，第二竖直轴线、第三竖直轴线和滑柱的中心轴线共面设置；第二竖直轴线位于第三竖直轴线和滑道之间。
可选地，冰箱配置成在竖梁处于折叠状态时，使滑柱抵靠于滑道在长度方向上远离第二竖直轴线的一端。
可选地，滑道在长度方向上远离第二竖直轴线的端部距第二竖直轴线的距离与第三竖直轴线距第二竖直轴线的距离之比大于5。
可选地，转动件包括一长圆形的环圈部，环圈部内侧构成滑道。
可选地，伸缩件具有两个沿第一门体宽度方向相互远离地延伸出的耳板；第一门体具有两个限位槽以分别容纳两个耳板；且弹性件的数量为两个且均为压簧，每个弹性件连接在一个耳板后表面与限位槽的后壁之间，在伸缩件处于伸出状态时，耳板在弹性件的弹力作用下抵靠于限位槽的前壁上。
可选地，驱动机构的数量为两个，两个驱动机构分别匹配竖梁的顶部和底部。
本发明的冰箱采用一种创新性的驱动机构实现竖梁的正确转动，舍弃了冰箱领域常用的利用导向件和导向槽引导竖梁转动的方案，从而避免因导向件和导向槽配合摩擦等因素而导致的竖梁转动卡顿、晃动，转动不畅的问题。当第一门体关闭过程中，伸缩件被箱体阻挡而向缩进位置移动，带动转动件绕第二竖直轴线转动，使滑道推动滑柱以带动竖梁转动至展开状态。第一门体打开过程中，伸缩件在弹性件弹力作用下朝伸出位置移动，以带动转动件转动，使滑道推动滑柱以带动竖梁转动至折叠状态。本发明通过简单的驱动 机构，使竖梁能随第一门体的开关动作而自动转动，结构非常巧妙。并且，由于无需设置导向件和导向槽，使得竖梁顶部/底部与储物间室顶壁/底壁之间可直接接触，使得密封性能更好，减少冷量流失。
进一步地，本发明的冰箱使第二竖直轴线、第三竖直轴线和滑柱的中心轴线共面设置，第二竖直轴线位于第三竖直轴线和滑道之间，并设定在竖梁处于折叠状态时，使滑柱抵靠于滑道在长度方向上远离第二竖直轴线的一端，以及使滑道在长度方向上远离第二竖直轴线的端部距第二竖直轴线的距离与第三竖直轴线距第二竖直轴线的距离之比大于5，都是为了使驱动机构运转阻力更小，使运转更加顺畅，使用户关门更加省力。同时也使伸缩件通过移动较小距离即可完成竖梁的一次转动，避免伸缩件长度超过第一门体厚度。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
下面参照图1至图6来描述本发明实施例的冰箱。其中，“前”、“后”、“上”、“下”、“顶”、“底”、“内”、“外”、“横向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
图1是根据本发明一个实施例的冰箱在第一门体10处于打开状态时的结构示意图；图2是图1中第一门体10、驱动机构60和竖梁50部分的示意性放大图；图3是图1所示冰箱在第一门体10处于关闭状态时的结构示意图；图4是图3中第一门体10、驱动机构60和竖梁50部分的示意性放大图。
如图1至图4所示，本发明实施例提供了一种冰箱。冰箱包括前侧敞开的箱体30、以对开方式可转动地设置在箱体30前侧的第一门体10和第二门体20、可绕第一竖直轴线X1转动地安装于第一门体10打开端的竖梁50、以及至少一个驱动机构60。
箱体30的前侧敞开即箱体30所限定的储物间室301是朝前敞开的(参考图5)。第一门体10和第二门体20以对开方式可转动设置在箱体30的前侧。例如图1，第一门体10和第二门体20沿横向方向并排设置，左侧的第一门体10的枢转轴线位于其左侧，右端为打开端。右侧的第二门体20的枢转轴线位于其右侧，左侧为打开端。
竖梁50可转动地安装在第一门体10的打开端。在第一门体10和第二门体20均处于关闭状态时，竖梁50将贴附在两个门体的内侧表面，以防止冷气泄漏至冰箱外部，如图3。在第一门体10打开过程中，竖梁50将朝后转动，以从大致平行于第一门体10的展开状态转动至与第一门体10呈预定角度(例如垂直于第一门体10)的折叠状态，以远离第二门体20，从而避免第一门体10打开过程中，使竖梁50被第二门体20阻挡，如图1。同理，在第一门体10关闭过程中，竖梁50将逐渐由折叠状态转动至展开状态，以封闭两个门体之间的间隙。
本领域技术人员应该理解的是，竖梁50也可安装于第二门体20而非第一门体10。但本发明实施例为描述方便，只介绍将竖梁50安装于第一门体10的方案。
如图2和图4所示，每个驱动机构60包括伸缩件61、弹性件62、转动件63和滑柱64。其中，伸缩件61可沿第一门体10的厚度方向(当第一门体10处于关闭状态时，其厚度方向平行于前后方向)伸缩地安装于第一门体10，以处于使其后端凸伸出第一门体10内侧表面的伸出位置(如图2)，或处于由伸出位置朝第一门体10内部缩进预设距离的缩进位置(如图4)。弹性件62配置成对伸缩件61施加促使其朝伸出位置移动的弹力。即，当伸缩件61处于缩进位置时，在弹性件62的弹力作用下，将具有朝伸出位置移 动的趋势。转动件63可绕第二竖直轴线X2转动地安装于第一门体10，且可绕第三竖直轴线X3转动地安装于伸缩件61，转动件63上形成有滑道631。滑柱64直接或间接固定于竖梁50且可沿滑道631滑动。
冰箱配置成在第一门体10处于打开状态时，使伸缩件61处于伸出位置，使竖梁50处于贴靠在第一门体10内侧的折叠状态，如图1和图2。在第一门体10关闭过程中，使伸缩件61被箱体30的阻挡而向缩进位置移动，带动转动件63绕第二竖直轴线X2转动，使滑道631推动滑柱64以带动竖梁50转动至展开状态，以便密封第一门体10和第二门体20之间的间隙，如图3和图4。在此过程中，驱动机构60利用伸缩件61的移动带动转动件63转动，通过转动件63的转动带动滑柱64移动，最终带动竖梁50转动。
可以理解的是，当第一门体10转动打开过程中，伸缩件61脱离箱体30的阻挡，在弹性件62弹力作用下逐渐伸出，从而带动转动件63绕第二竖直轴线X2转动，以使滑道631推动滑柱64带动竖梁50转动至折叠状态。
本发明实施例通过简单的驱动机构60，使竖梁50能随第一门体10的开关动作而自动转动，结构非常巧妙。并且，由于无需设置导向件和导向槽，使得竖梁50顶部/底部与储物间室顶壁/底壁之间可直接接触，使得密封性能更好，减少冷量流失。而且，由于无需设置导向件和导向槽，可避免因导向件和导向槽配合摩擦等因素而导致竖梁转动卡顿、晃动，转动不畅的问题。
在一些实施例中，如图2和图4所示，驱动机构60还可包括连杆65。连杆65与竖梁50固定连接且朝远离竖梁50的方向延伸出，滑柱64安装于连杆65的远离竖梁50的一端。如此，使得滑柱64远离竖梁50的第一竖直轴线X1，使得力臂(即滑柱64与第一竖直轴线X1的距离)更长，以便可对滑柱64施加更小的力即可使其带动竖梁50转动。
可使连杆65临近竖梁50的端部可转动地安装于第一门体10，以便竖梁50绕第一竖直轴线X1转动。即，竖梁50是通过连杆65安装于第一门体10的，以无需在竖梁50上另外设置转动连接结构。可使连杆65与竖梁50之间为不同部件，通过紧固结构固定连接。也可使连杆65与竖梁50的外壳为一体成型的整体件。
在一些实施例中，如图2和图4所示，可使第二竖直轴线X2、第三竖直轴线X3和滑柱64的中心轴线共面设置，并使第二竖直轴线X2位于第三竖直轴线X3和滑道631之间。冰箱配置成在竖梁50处于折叠状态时，使滑 柱64抵靠于滑道631在长度方向上远离第二竖直轴线X2的一端，如图2，以便在伸缩件61处于伸出位置时，使竖梁50较稳固地保持在折叠状态。可进一步使滑道631在长度方向上远离第二竖直轴线X2的端部(A端)距第二竖直轴线X2的距离(即A至X2距离)与第三竖直轴线X3距第二竖直轴线X2的距离(即X2至X3距离)之比大于5，优选大于7，以便使驱动机构60运转阻力更小，运转更加顺畅，使用户关门更加省力。同时也使伸缩件61通过移动较小距离即可完成竖梁50的一次转动，避免伸缩件61长度超过第一门体10厚度。
在一些实施例中，如图2和图4所示，可使转动件63包括一个长圆形的环圈部630，环圈部630内侧构成滑道631。滑柱64可为圆柱形，其外径稍小于滑道631宽度，以便沿滑道631长度方向移动。可使滑柱64可绕自身中心轴线转动地安装于连杆65，以便能沿滑道631内壁滚动，减少滑动摩擦。
在一些实施例中，如图2和图4所示，可使伸缩件61具有两个沿第一门体10宽度方向相互远离地延伸出的耳板612。第一门体10具有两个限位槽110以分别容纳两个耳板612。弹性件62的数量为两个且均为压簧，每个弹性件62连接在一个耳板612后表面与限位槽110的后壁112之间。在伸缩件61处于伸出状态时，耳板612在弹性件62的弹力作用下抵靠于限位槽110的前壁111上。第一门体10上可开设有滑槽11，伸缩件61可滑动地安装于滑槽11内，以实现其伸缩运动。两个限位槽110位于滑槽11的宽度方向的两侧。
图5是图1中箱体30、第一门体10、竖梁50和驱动机构60的分解示意图；图6是图5中驱动机构60和竖梁50部分的结构示意图。
如图5和图6所示，可使伸缩件61、转动件63以及连杆65在竖直方向错位排列，以避免出现干涉。
在一些实施例中，如图5和图6所示，可使驱动机构60的数量为两个，使两个驱动机构60分别匹配竖梁50的顶部和底部，以使竖梁50上下方向受力更加均匀，转动更加顺畅。上下两个驱动机构60可对称设置。
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。
