Description

冰箱
本申请要求了申请日为2013年06月07日，申请号为201310225558.5，发明名称为“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申请中。
【技术领域】
本发明涉及一种制冷技术领域，尤其涉及一种冰箱。
【背景技术】
目前市场上带立梁的对开门冰箱中，立梁与冷藏左箱门或者右箱门装配，门体打开时，利用冰箱上导向柱与立梁导向槽的作用，立梁随左箱门或者右箱门打开后呈翻转状态，也就是说，立梁旋转到与门面垂直，贴在门体侧面，方便用户存取物品；当门体关闭时，利用导向柱的作用，立梁旋转，与门面平行，门体顺畅关闭。但经常有用户将门体打开后，无意识的将立梁置于与门体平行位置，这样，门体关闭时，因为立梁与导向柱干涉，导致门体关闭不严，漏冷。
现有技术中，冰箱立梁导向槽采用单轨道闭合，单轨道打开的结构形式，正常关闭时，导向柱沿缺口进入导向槽，引导门体正常关闭。当立梁位置不当时，导向柱会直接撞向导向槽的侧面，不能沿导向槽滑入，导致门体不能很好的闭合，冰箱漏冷，如果用户频繁这样关门，严重的会导致立梁或导向柱损坏。
针对此状况，市场上出现了一种防撞结构：在立梁一端设置了可上下伸缩的导向柱，当门体非正常关闭时，导向柱撞向导向槽侧面，导向柱利用弹性，压缩后进入导向槽，引导门体正常关闭。而已有的防撞机构是将导向柱做成可伸缩的，导向柱结构增大，相应的导向槽结构和立梁尺寸也增大，占用空间大。
【发明内容】
本发明对现有技术进行了改进，提供了一种方案简单、门体关闭时立梁归位稳定、闭合制冷效果好的冰箱。
本发明是这样实现的：一种冰箱，包括箱体，门体枢轴连接至所述箱体的前侧；立梁，沿竖向延伸设置于门体，且可转动的安装在远离所述门体枢轴的一侧；导向柱；防撞机构，所述防撞机构设置有导向槽，所述导向柱可移动地配合在所述导向槽内，以便打开或关闭所述门体时通过导向柱在所述导向槽内移动使立梁翻转或者展开；所述防撞机构进一步包括相对导向槽左右移动设置的导引部，以及靠近导向柱设置且位于导向槽同一侧的第一开口及第二开口，所述第一开口引导所述导向柱进入或脱离所述导向槽，所述第二开口在导引部的作用下单向引导所述导向柱进入导向槽。
优选地，所述导向柱设置于所述立梁上端或下端中的至少一端，所述防撞机构设置于所述箱体的内壁。
优选地，所述导向柱设置于所述立梁的上端。
优选地，所述防撞机构设置于所述箱体的顶壁。
优选地，所述所述防撞机构进一步包括用于控制导引部位置的限位机构。
优选地，所述导引部包括滑块，以及连接于所述滑块的弹性件，所述滑块上开设有滑槽，所述滑槽包括滑槽开口以及弧形侧壁。所述弧形侧壁在弹性件的作用下抵挡所述第二开口，所述滑槽开口宽度大于所述第二开口
优选地，所述第一开口与第二开口位于同一平面。所述第一开口与第二开口之间设置有间距。
优选地，所述导向柱进入所述第二开口时推动所述弧形侧壁使所述滑块向左移动，导向柱沿所述滑槽开口进入到所述导向槽内部。
本发明在原来的运行轨道的基础上增加了一个导入口，即导向柱撞向导向槽侧面时，导向柱可直接从增加的导入口，通过滑槽进入立梁的导向槽。因为导向槽的限位结构，决定了导向柱只能从该处进入，不能从该处出，保证门体顺畅打开。导向柱通过双导入口，单导出口的防撞结构，可以保证不管立梁出于何种状态，门体都能够正常地关闭。解决了门体因关闭不严导致的漏冷或立梁位置不对导致立梁撞坏的问题，保证立梁在非正常状况下也能顺畅关闭。并且，本发明充分考虑目前冰箱行业中相关部件的结构及尺寸，分析了采用双导入口防撞结构时，开关门过程中导向柱与导向槽配合的受力及运行轨迹。本发明基于模块化的设计理念，防撞机构以总成方式供货，即简化了供货方式，也提高了组装现场的生产效率；结构设计也充分兼顾了部件通用性，在冰箱产品上，即可选用本发明部件，也可以选用原有结构，增加了产品的差异化。

【具体实施方式】
以下将结合附图所示的各实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
参照图1、图3所示，本发明实施方式的冰箱包括箱体10、门体20。门体20包括左箱门和右箱门，本实施方式中具体以左箱门为例进行说明。门体20通过铰链（图中未示出）枢轴地连接于箱体10的前侧，当然，也可以通过业界其它技术手段将门体20枢轴地设置于箱体10上。需要说明的是，这里所指的前侧是指冰箱面对使用者的一侧。立梁30可转动地安装在门体20上远离铰链轴的一侧上，本实施方式中，立梁30沿竖直方向设置于门体20上，且可转动的安装在远离门体20枢轴的一侧，也就是说，门体20相对箱体10在打开或闭合时，立梁30相对门体20可以在互成角度的翻转位置以及相互平行的平展位置间转动；为了使立梁30与门体20之间运动相对稳定、可靠，可以在立梁30与门体20之间可设置弹性件，例如扭簧（图中未示出）。本发明实施方式中将以门体20为例对其开启、关闭进行详细说明。当门体20与箱体10配合时，设置于箱体10与立梁30之间的闭合机构40能有效地将门体20与箱体10连接在一起，从而使冰箱门体20密闭箱体10而实现冰箱内不漏冷。
参照图2、图4所示，闭合机构40包括导向柱32、以及与导向柱32配合作用的防撞机构42。立梁30包括立梁本体31，立梁本体31的至少一端设置有导向柱32。本实施方式中，导向柱32设置于立梁本体31的上盖，即立梁本体31的顶端；防撞机构42设置于箱体10的内壁，防撞机构42通常设置于箱体10的顶壁或底壁的前侧且靠近导向柱32；本实施方式中防撞机构42设置于箱体10的顶壁。导向柱32与防撞机构42可选择地分离或配合，从而实现门体20与箱体10打开或闭合。防撞机构42设置有导向槽44，导向柱32可选择地进入或脱开导向槽44，当导向柱32进入导向槽44时，门体20关闭箱体10；打开门体20时，门体20带动立梁30旋转，导向柱32与导向槽44脱离。在通常状况下箱体10是由门体20所闭合的，立梁30与门体20基本处于平行的状态。当外向侧拉门体20打开箱体10时，立梁导向柱32在防撞机构42的作用下带动立梁30旋转至与门体20大致垂直的翻转位置，贴在门体20侧面，方便用户存取物品；由于立梁30相对门体20可翻转地设置，因此有的用户将门体打开后，可能无意识的将立梁30置于与门体20平行的平展位置；当关闭门体20时，利用闭合机构40的作用，立梁30最终旋转至与门体20平行的平展状态，门体顺畅关闭。
参照图5、图6所示，防撞机构42包括盖体46、以及与盖体46配接的主体48。盖体46上设置了限位结构45a和卡扣45b；主体48上设置有第一开口、第二开口以及导向槽44；第一开口与第二开口位于导向槽44的同一侧平面内，且第一开口与第二开口之间设置有一定的间距。下文中将第一开口称为进出口43a，将第二开口称为单向入口43b，进出口43a及单向入口43b分别与导向槽44连通，。盖体46与主体48之间进一步设置有导引部，导引部包括滑块49，滑块49大致于中间部位开设有滑槽，滑块49上靠近卡扣45b的端部设置连接端49b，一弹性件连接于盖体46的卡扣45b与连接端49b之间；滑槽具有滑槽开口49a以及弧形侧壁49c，该弧形侧壁49c在弹性件作用下，抵挡第二开口即单向入口43b，滑槽开口49a宽度大于单向入口43b。参照图8，通常状况下，滑块49在弹性件的拉力作用下向卡扣45b方向抵靠。本实施方式中弹性件采用的是拉簧47，当然拉簧47也可以用其它具有类似功能的弹性装置替换。组装后的防撞机构42以总成的方式供货和安装，即简化了零部件的供货，也提高了组装线的生产效率；结构设计也充分兼顾了部件通用性，模块化的设计从而增加了冰箱产品的可选性，增加了产品的差异化。
图6所示的位于立梁本体31顶端的导向柱32靠近防撞机构42的第一开口及第二开口设置，当关闭冰箱门体20时，根据立梁30所处的不同位置，导向柱44可选择地从单向入口43b或者进出口43a进入导向槽44；当打开冰箱门体20时，导向柱32仅能从进出口43a退出导向槽44。
参照图7、图8所示，当立梁30相对门体20处于平展位置，关闭冰箱门体20时，导向柱32在导引部的作用力从单向入口43b进入导向槽44。导向柱32及滑块49的运行轨迹如下：从导向柱32与导向槽44接触临界位置a开始，导向柱32沿单向入口43b进入导向槽44，导向柱32抵靠于滑块49的弧形侧壁49c并推动滑块49向左移动并嵌合于滑槽开口49a中。在关闭门体20的作用力下，导向柱32沿导向槽44内侧壁运行，沿箭头b指示的方向到达极限位置c，也就是门体20正常关闭的位置；导向柱32在导向槽44内运行的同时带动滑块49克服拉簧47作用力向左沿箭头d指示的方向由实线所示的初始位置移动至虚线所示的终端位置，而当导向柱32到达位置c时，导向柱32脱开滑块49，滑块49在拉簧47拉力作用下以及限位机构45a的限位作用下向右移动恢复至初始位置。
参照图9、图10所示，当立梁30相对门体20处于大致垂直的翻转位置，即立梁处于正常状况下，关闭冰箱门体20，导向柱32从进出口43a进入导向槽44。导向柱32相对导向槽44的运行轨迹如下：从导向柱32与导向槽44接触临界位置a’开始，导向柱32在门体20关闭的作用力下沿导向槽44内侧壁运行，沿箭头b’指示的方向到达极限位置c，立梁30枢转至与门体20平行，此时门体20自然关闭。
参照图11所示，门体20处于关闭状态时，立梁30与门体20处于平行状态；当门体20开启时，只需要在门体20的把手（图中未示出）上施于向外的拉力，使得导向柱32沿导向槽44运行并最终脱开导向槽44。导向柱32相对导向槽44的运行轨迹如下：导向柱32受门体20拉力作用下，从位置c抵靠在滑块49的弧形侧壁49c，此时滑块49受力，因为受盖体46限位结构45a的作用，滑块49并不能向卡扣45b方向运行，故导向柱32只能沿滑块49并在导向槽44内沿箭头b’’指示方向运行，直至到达临界位置a’’， 即导向柱32到达进出口43a与导向槽44相脱离，同时立梁30在扭簧(图中未示出)作用下，枢转至与门体20大致成垂直状态，此时门体20自然打开。
综上所述，从导向柱32在门体20打开的运行轨迹可以看出，由于受滑块49及导向槽44的作用，导向柱32是从导向槽44的进出口43a退出后与导向槽44相脱离。从导向柱32在门体20关闭的运行轨迹可以看出，单向入口43b 和进出口43a分别为导向柱32提供了立梁30处于不同位置或状态时进入导向槽44的入口，从而保证了冰箱在打开时无论立梁30处于平展位置或翻转位置，立梁30的导向柱32都能与防撞机构42很好的配合，从而顺畅的关闭箱门，获得较好的致冷效果。
本实施方式中的导引部相当于一个单向作用机构，也就是说，导引部不仅能引导导向柱32从单向入口34a进入导向槽44，同时能引导导向柱32从进出口43a退出。本发明的冰箱采用了上述结构，使得门体20在关闭时，能够防止立梁30或导向柱32被撞坏；实现了冰箱门体关闭时，立梁30与防撞机构42实现双轨道闭合，而在打开冰箱门体时，实现单轨道打开冰箱门结构方式，即使立梁30在非正常状况下也能顺畅关闭，结构简单且性能稳定，保证冰箱的较好的致冷效果。
本发明实施方式的防撞机构42设置在箱体上的，本领域技术人员比较容易设想，将防撞机构42这样的模块组件设置于立梁上，而导向柱32设置于箱体上。导向柱32与防撞机构42之间的配合作用同样能实现本发明要求保护的技术方案。
参照图12、图13所示，为本发明的第二种实施方式，为表述方便，相同的结构以同一编号表示并不作赘述。立梁沿竖直方向枢轴设置于门体上并远离枢轴（图中未示出），闭合机构40’包括设置于立梁30端部的防撞机构42’，以及设置于箱体的导向柱32。防撞机构42’包括单向入口43b’、进出口43a’以及分别连通进出口43a’及单向入口43b’的呈弧形的导向槽44’。单向入口43b’和进出口43a’分别位于导向槽44’的不同的部位；也就是说，单向入口43b’位于弧形导向槽44’的外侧端，而进出口43a’则设置于远离远离门体枢轴的导向槽44’的端侧；单向入口43b’所处的平面及进出口43a’所处的平面大致呈90度的角度设置。导引部49’ 相当于一个单向作用机构，其作用与第一实施方式相类似，通常状况下，导引部49’在弹性件的作用下闭合单向入口43b’，只有当立梁处于平展位置时关闭门体时，导向柱32从单向入口43b’处作用于导引部49’，导引部49’运动将导向柱32导入导向槽44’中，并在外部推力作用下门体自动关闭。当立梁处于翻转位置时关闭门体时，导向柱32从进出口43a’进入导向槽44’， 并在外部推力作用下门体自动关闭。当打开门体时，导向柱32在门体的外部拉力作用下由进出口43a’退出并与导向槽44’脱开。
本发明的冰箱采用了门体在关闭时，使导向柱与防撞机构实现双轨道闭合，而在打开冰箱箱门时实现单轨道打开冰箱门体结构方式，即使立梁在非正常状况下也能顺畅关闭，结构简单且性能稳定，保证冰箱的较好的致冷效果。
