Description

冰箱 技术领域
本发明涉及制冷装置领域，尤其涉及一种冰箱。
背景技术
随着厨电一体化需求日益增加，将冰箱嵌入橱柜内的需求也逐渐增加。将冰箱嵌入橱柜内需要避免门体在转动过程中干涉到冰箱的箱体以及橱柜，并且用户也更期望冰箱与橱柜的间隙更小，从而可以使得整体家居的美观度更高。
单轴铰链装置由于结构简单且成本较低被广泛应用于冰箱中，然而，将冰箱嵌入橱柜后，单轴铰链装置由于无法变轴心导致冰箱门体在打开至90°时会出现门体朝向箱体内移动的现象，这导致箱体内的抽屉被抽出时会被门体阻挡，从而需要设计更小的抽屉才可以避免门体在打开至90°时阻挡抽屉被抽出。
现有部分嵌入式冰箱，将所述单轴铰链装置中的轴孔设置为长轴孔，以通过铰链轴于所述长轴孔内平移以改变门体转动轴心的位置，实现所述门体的平移，但是，门体转动过程中，所述铰链轴于所述长轴孔内易产生晃动，从而产生不必要的平移，导致无法准确控制所述门体的运动轨迹。

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，请参照图1-图13所示，为本发明的较佳实施方式，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同 或类似功能的元件。但应当说明的是，这些实施方式并非对本发明的限制，本领域普通技术人员根据这些实施方式所作的功能、方法、或者结构上的等效变换或替代，均属于本发明的保护范围之内。
图1示出了根据本发明一具体实施方式中的冰箱的示意性立体图。图2示出了根据本发明一具体实施方式中去除铰链总成后的冰箱的示意性俯视图，其中仅示出一侧的橱柜4，实际安装中，冰箱是整个嵌入橱柜4中的。可以理解的是，冰箱不一定是嵌入橱柜4内，也可以是嵌入墙体内。如图1和图2所示，该冰箱一般性地包括箱体1、门体2和用于连接箱体1和门体2的铰链总成3。该门体2包括前壁22、铰链安装侧23和枢转侧21，该门体2的前壁22为冰箱在嵌入橱柜4时面向外部环境的一侧。该门体2的铰链安装侧23为门体2的顶侧和/或底侧，在以下实施例中，以铰链安装侧23为顶侧为例进行说明。该门体2的枢转侧21指所述门体2相对所述箱体1转动的一侧。在所述铰链总成3安装于所述门体2的左端时，所述枢转侧21即指所述门体的左侧，在所述铰链总成3安装于所述门体2的右端时，所述枢转侧21即指所述门体2的右侧。
如图3至图5所示，所述铰链总成3包括固定连接于所述箱体1上的铰链座31、设于所述铰链座31上的铰链轴32、设于所述门体2的铰链安装侧23上且与所述铰链轴32相配合的轴孔部232。该轴孔部232上限定形成有沿门体的厚度方向延伸的长轴孔2321，通过所述铰链轴32与所述长轴孔2321之间的配合将所述门体2转动连接至所述铰链座31上。
具体地，所述铰链座31包括用以与所述门体2相连接的第一连接端311、与所述箱体1相连接的第二连接端312。所述铰链轴32设置于所述第一连接端311上，以实现与所述门体2之间的连接。
所述长轴孔2321具有相对的第一端、第二端，且所述第一端相较于所述第二端更靠近所述门体2的前壁22。在所述铰链轴32沿所述长轴孔2321移动时，能够带动所述门体2平移。在所述门体2处于关闭状态时，所述铰链轴32位于所述第一端。
进一步地，所述铰链总成3还包括设于所述铰链座31与所述铰链安装侧23中的一个上的凸轮结构、设于另一个上与所述凸轮结构相配合的引导件33。在所述门体2旋转打开的过程中，所述引导件33沿所述凸轮结构的轮廓曲线移动，带动所述铰链轴32沿所述长轴孔2321移动，从而，使所述门体2平移。能够使所述冰箱适用于多个场景，如嵌入式场景，且结构简单。
可知的是，所述凸轮结构以及所述引导件33的具体设置位置可根据具体需求进行调整。下面，以所述凸轮结构设置于所述铰链安装侧23上，而所述引导件33设置于所述铰链座31上为例进行具体阐述。当然，并不以此为限。
于一具体实施方式中，所述引导件33包括转轴、套设于所述转轴上的滚轮，通过所述滚轮与所述凸轮结构相配合，能够减少摩擦，降低噪音。
进一步地，所述门体2上与所述凸轮结构的轮廓曲线相对应的位置处凹设有让位槽231，所述让位槽231的形状与所述凸轮结构的轮廓曲线相同，所述引导件33延伸至所述让位槽231内，能够保证在对门体2进行上下调节时不会出现所述引导件33与所述凸轮结构的轮廓曲面脱开接触的情况，从而避免所述引导件33与所述凸轮结构组成的机构的失效。
可以理解的是，所述凸轮结构并不限于具体的凸轮，也可以是呈凸轮状，如呈凸轮状的导槽。
进一步地，所述铰链总成3还包括设于所述铰链座31上的止挡筋34以及设置于所述铰链安装侧23上的定位槽233。所述定位槽233用以限制所述止挡筋34的移动，以使所述铰 链轴32保持于所述第一端，或者自所述第二端移动至所述第一端。通过使用所述止挡筋34以及与之配合的定位槽233的配合结构，代替现有的弹性机构能够避免出现因为弹性机构失效导致的机构失效，进一步提高门体2的可靠性以及稳定性。
具体地，所述止挡筋34呈与所述铰链轴32同心设置的圆弧状。且所述止挡筋34与所述铰链轴32、引导件33之间均间隔布置。
可以理解的是，所述止挡筋34与所述铰链轴32之间的距离不变，通过限制所述止挡筋34的位置可限制所述铰链轴32的位置。且所述止挡筋34呈圆弧状，从而，在所述止挡筋34位于与其形状相匹配的滑槽部内时，所述止挡筋34不会晃动，从而限制所述铰链轴32晃动，增强所述门体2运动的稳定性。
具体地，所述定位槽233具有第一滑槽部2331和第二滑槽部2332，在所述铰链轴32位于第一端时，所述止挡筋34位于所述第一滑槽部2331，在所述铰链轴32位于所述第二端时，所述止挡筋34位于所述第二滑槽部2332。所述止挡筋34与所述铰链轴32之间的距离一定，故，该第一滑槽部2331与第一端之间的距离等于第二滑槽部2332与第二端之间的距离，且第一滑槽部2331相比于第二滑槽部2332更靠近所述第一端。
所述门体2打开至第一预设角度时，所述引导件33沿所述凸轮结构移动至距离所述第一端最远的位置处，止挡筋34移动至第二滑槽部2332，同时铰链轴32自第一端移动至第二端，第一预设角度为范围在80°-100°中任一值，例如可以为80°、85°、90°、95°或100°。这里，由于止挡筋34是具有一定长度的，因此，止挡筋34移动至第二滑槽部2332中，并不是指止挡筋34部分移动至第二滑槽部2332，而是指止挡筋34全部移动至第二滑槽部2332。可以理解的是，在门体2转动过程中，铰链座31是不动的，设置于所述铰链座31上的铰链轴32、引导件33和止挡筋34一起保持不动。因此，该铰链轴32的轴心从第一端移动至第二端均是相对移动，实际运动中，是该门体2转动导致门体2上的轴孔部232、让位槽231和定位槽233跟随转动，从而使得铰链轴32相对于该长轴孔2321运动，使得该引导件33相对于该让位槽231移动，且使得止挡筋34相对于定位槽233移动。
根据本发明的方案，通过引导件33与让位槽231配合，且止挡筋34与定位槽233配合，由此可以实现在不使用弹性机构的前提下，实现驱动铰链轴32的轴心变动，从而避免出现由于弹性机构失效导致的前述配合的机构的失效，增强所述门体2运动的稳定性。
进一步地，所述定位槽233还包括过渡滑槽部，所述过渡滑槽部平滑连接于所述第一滑槽部2331和所述第二滑槽部2332之间。所述凸轮结构的轮廓曲线包括平滑连接的第一段2311、第二段2312，所述第二段2312相较于所述第一段2311更靠近所述枢转侧21。
具体地，所述第一段2311为以所述第一端为圆心的圆弧状，在所述门体2自关闭状态转动打开至第二预设角度时，所述引导件33沿所述第一段2311移动至所述第一端2311与所述第二段2312之间的第一交界线处，所述铰链轴32保持在所述第一端，所述门体2原地转动。此时，所述止挡筋34自所述第一滑槽部2331移动至与所述第一滑槽部2331与所述过渡滑槽部之间的第一交界部处。
第二预设角度小于第一预设角度。可以理解的是，该止挡筋34从第一滑槽部2331移动至第一滑槽部2331与过渡滑槽部之间的第一交界部处，是指该止挡筋34全部移动至第一交界部处，并不是部分移动至第一交界部处。该第二预设角度为50°-60°中任一值，例如可以为50°、55°或60°。其中，该止挡筋34移动第一交界部处是指，该止挡筋34的靠近所述第一滑槽部2331的一端已经移动至该第一交界部处，此时，该止挡筋34的另一端可能已经移动至第二滑槽部2332。
在所述门体2自第二预设角度继续转动至打开第一预设角度时，引导件33沿所述第一交界线移动至第二段2312远离所述第一段2311的一端，即所述轮廓曲线距离所述第一端最远的位置处。所述止挡筋34从第一交界部经过过渡滑槽部移动至第二滑槽部2332内，同时铰链轴32自第一端移动至第二端，带动所述门体2沿第一方向移动，以防止门体2影响所述箱体1内的抽屉等的抽出。
具体地，上述第一方向是指处于关闭状态下的门体2自其中心指向所述枢转侧21的方向。
进一步地，该定位槽233还包括位于所述第二滑槽部2332远离所述第一滑槽部2331的一端的第三滑槽部2333，第三滑槽部2333为以所述第一端为圆心的圆弧。在所述止挡筋34自所述第二滑槽部2332移动至所述第三滑槽部2333内时，所述铰链轴32自第二端复位至第一端。
具体地，所述凸轮结构的轮廓曲线还包括位于所述第二段2312远离所述第一段2311的一端的第三段2313。沿远离所述第二段2312的方向，所述第三段2313逐渐靠近所述长轴孔2321。从而，在所述引导件33沿所述第三段2313移动时，能够带动所述铰链轴32自第二端向第一端移动。
所述过渡滑槽部同时平滑连接所述第二滑槽部2332与所述第三滑槽部2333，门体2自第一预设角度继续转动至打开第三预设角度时，引导件33于所述第三段2313内向远离所述第二段2312的方向移动，带动所述铰链轴32自第二端向第一端移动。所述止挡筋34自第二滑槽部2332经所述过渡滑槽部移动至第三滑槽部2333，第三预设角度大于第一预设角度。该第三预设角度为大于或等于120°，且小于或等于140°，例如该第三预设角度为120°、130°或140°。
进一步地，所述轴孔部232的外周缘为圆弧形，轴孔部232的外周缘作为所述定位槽233的内槽壁，使得该铰链总成3以及门体2的铰链安装侧23对应的结构设计的更为简单，且结构可靠。
进一步地，所述门体2转动过程中，所述门体2绕门体转动轴心转动，所述门体转动轴心位于目标区域内或者位于所述目标区域的边界上。
对于具有所述铰链轴32以及与所述铰链轴32相配合的所述长轴孔2321的实施方式中，在门体2转动过程中，所述门体2绕所述铰链轴32转动，即，所述铰链轴32即为门体转动轴心。对应的，所述长轴孔2321的位置即为所述门体转动中心的位置。
进一步地，所述第一端位于所述目标区域内或者位于所述目标区域的边界线上。
优选的，所述长轴孔2321位于目标区域内或者位于所述目标区域的边界上，以使铰链轴32一直处于所述目标区域内或者位于所述目标区域的边界上。通过限定目标区域，从而可以在确定的目标区域内进行调试长轴孔2321的位置，减少调试时间。当然，并不以此为限。
下面以所述长轴孔2321位于所述目标区域内或者位于所述目标区域的边界线上为例进行说明。
可以理解的是，限定所述长轴孔2321的位置即限定了所述门体转动轴心的位置。
进一步地，所述目标区域位于第一轨迹线远离所述箱体1的一侧，在所述长轴孔2321位于所述第一轨迹线上时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端与所述橱柜4相切。在所述长轴孔2321位于目标区域内时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端与橱柜4之间具有间隙。从而，在所述长轴孔2321位于 由所述第一轨迹线限定的目标区域内或者位于该目标区域的边界上时，所述门体2不会与所述橱柜4产生碰撞等其他干涉。
可以理解的是，在仅有所述第一轨迹线的实施方式中，上述的边界线即指所述第一轨迹线。
本发明中的门体2在转动的过程中，使门体转动轴心始终位于所述目标区域内或者位于所述目标区域的边界线上，从而，可以保证门体2转动过程中，门体2始终不会干涉橱柜4。与现有技术中人为地根据经验不断调试来确定合适的门体转动轴心的方式相比，本发明可以在确定的目标区域内进行调试，能够保证无论如何调试都不会干涉橱柜4，从而避免在调试过程中反复出现干涉橱柜4从而增加调试时间的现象。
具体地，所述第一轨迹线的拟合方法包括如下步骤：
如图6所示，以处于关闭状态下的所述门体2的前壁22与门体2的铰链安装侧23的第一交线为X轴，以处于关闭状态下的所述门体2的枢转侧21与门体2的铰链安装侧23的第二交线为Y轴，并以所述X轴和所述Y轴的交点作为原点O，构建XY坐标系；
按照公式x＝(y 2-A 2)/2A在所述XY坐标系内绘制出所述第一轨迹线E，其中，如图2中所示，A表示门体2处于关闭状态时所述门体2的枢转侧21与橱柜4之间的第一间隙。
可以理解的是，上述的原点为所述门体2的前壁22位于枢转侧21的一端。
在拟合出所述第一轨迹线后，所述第一轨迹线将处于关闭状态的所述门体2的铰链安装侧23分为两个区域，以位于所述第一轨迹线远离箱体1的一侧的区域为目标区域。
进一步地，公式x＝(y 2-A 2)/2A中y的范围为：0≤y≤T，其中，T表示所述门体2的厚度值。以使确定出的所述目标区域位于门体2的厚度值范围内。当然，并不以此为限，在所述门体转动轴心设置于门体22外部的实施方式中，也可以适应性扩大所述y的取值范围，如-T/2≤y≤T；或者所述y的范围也可以设置为使所述目标区域位于所述铰链安装侧23上，以便于长轴孔2321的设置。
优选地，公式x＝(y 2-A 2)/2A中，在A＝3时，0≤y≤T/4；在A＝4时，0≤y≤3T/10；在A＝6时，0≤y≤2T/5；在A＝10时，0≤y≤T/2；在A＝18时，0≤y≤3T/5。
其中，公式x＝(y 2-A 2)/2A的获得方法是：设定门体转动轴心在XY坐标系上的坐标为(x,y)，其中，x表示门体转动轴心的横坐标，y表示门体转动轴心的纵坐标。假设门体转动轴心到原点的距离为R 1，则门体2在转动过程中，原点在以轴心(x,y)为圆心同时半径为R 1的圆上运动，为了避免门体2与橱柜4干涉，则要保证原点不与橱柜4干涉，因此需要满足以下条件：R 1-x≤A且x 2+y 2＝R 1 2，取R1-x＝A，则经过换算可得：x 2+y 2＝(x+A) 2，分解公式可以得到上述公式x＝(y 2-A 2)/2A。
可以理解的是，在R 1-x＝A时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端与橱柜4相切。即，在所述门体转动轴心位于以公式x＝(y 2-A 2)/2A绘制出的第一轨迹线上时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端始终与橱柜4相切。
假设门体2的厚度值T和第一间隙A为固定值，那么根据公式x＝(y 2-A 2)/2A以及y的范围0≤y≤T可以绘制出图6所示的第一轨迹线E。若圆心为第一轨迹线E中各个点，则如图6所示，第一轨迹线E上的点到原点的距离作为半径，则通过原点的圆都会与橱柜4相切，即，在所述门体转动轴心/长轴孔2321位于所述第一轨迹线E上时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端与橱柜4相切。而若圆心处于第一轨迹线E远离所述箱体1的一侧的某一点，则如图7所示，通过原点的圆则会与橱柜4有间隙，即，在所述门体转动轴心/长轴孔2321位于所述第一轨迹线E远离所述箱体1的一侧时，门体2转动过 程中，所述门体2的前壁22位于枢转侧21的一端与橱柜4有间隙。因而，在所述门体转动轴心/长轴孔2321位于由所述第一轨迹线E限定的所述目标区域内或者位于该目标区域的边界线(第一轨迹线E)上时，门体2的前壁22位于枢转侧21的一端与橱柜4相切或有间隙，不会与所述橱柜4干涉。
进一步地，所述目标区域位于所述第二轨迹线靠近所述枢转侧21的一侧，在所述门体转动轴心位于所述第二轨迹线上时，门体2转动过程中，所述门体2的后壁位于枢转侧21的一端与所述箱体1相切。在所述门体转动轴心位于所述第二轨迹线靠近所述枢转侧21的一侧时，门体2转动过程中，所述门体2的后壁位于枢转侧21的一端与所述箱体1之间具有间隙，即，门体2转动过程中，所述门体2与所述箱体1之间不会产生干涉。
于一具体实施方式中，所述目标区域由第一轨迹线E以及第二轨迹线共同限定，所述边界线包括第一轨迹线E以及第二轨迹线。当然，并不以此为限，于其他实施方式中，所述目标区域也可以仅由所述第二轨迹线限定，此时，所述边界线即为所述第二轨迹线。
在所述门体转动轴心位于由所述第一轨迹线E以及第二轨迹线共同限定的目标区域内时，所述门体2的后壁位于枢转侧21的一端与所述箱体1之间具有间隙，同时，所述门体2的前壁22位于枢转侧21的一端与橱柜4之间具有间隙，即，门体2转动过程中，所述门体2与橱柜4以及与箱体1之间均不会产生干涉。
在所述门体转动轴心位于作为目标区域的边界线的第一轨迹线上时，所述门体2的前壁22位于枢转侧21的一端与橱柜4之间相切，所述门体2的后壁位于枢转侧21的一端与所述箱体1之间具有间隙。在所述门体转动轴心位于作为目标区域的边界线的第二轨迹线上时，所述门体2的前壁22位于枢转侧21的一端与橱柜4之间具有间隙，所述门体2的后壁位于枢转侧21的一端与所述箱体1之间相切。故，门体2转动过程中，只要确定所述门体转动轴心位于所述目标区域内或者该目标区域的边界线上，即可保证所述门体2与橱柜4以及与箱体1之间均不会产生干涉。与现有技术中人为地根据经验不断调试来确定合适的长轴孔2321的位置的方式相比，本发明可以在确定的目标区域内进行调试，能够保证无论如何调试都不会干涉橱柜4以及箱体1，从而避免在调试过程中反复出现干涉橱柜4和/或干涉箱体1从而增加调试时间的现象。
进一步地，所述第二轨迹线的拟合方法包括如下步骤：
以处于关闭状态下的所述门体2的前壁22与门体2的铰链安装侧23的第一交线为X轴，以处于关闭状态下的所述门体2的枢转侧21与门体2的铰链安装侧23的第二交线为Y轴，并以所述X轴和所述Y轴的交点作为原点O，构建XY坐标系；
按照公式y＝T-(x 2-B 2)/2B在所述XY坐标系内绘制出所述第二轨迹线，其中，B表示门体2处于关闭状态时所述门体2与所述箱体1之间的第二间隙，T表示所述门体2的厚度值。
进一步地，公式y＝T-(x 2-B 2)/2B中x的范围0≤x≤L，其中，L表示所述门体2的宽度值。以使确定出的所述目标区域位于门体2的宽度值范围内。当然，并不以此为限，在需要使所述目标区域位于铰链安装侧23上时，也可以适应性缩小所述x的取值范围。
在拟合出所述第二轨迹线后，所述第二轨迹线将处于关闭状态的所述门体2的铰链安装侧23分为两个区域，以位于所述第二轨迹线靠近枢转侧21的一侧的区域为目标区域。
具体地，如图2所示，所述铰链安装侧23包括包括四条边，分别为前边、后边、左边和右边，其中，前边为X轴所在边，右边为Y轴所在边，前边与右边的交点为原点，后边与右边的交点定义为N点。
可以理解的是，所述N点位于所述门体2的后壁与所述枢转侧21相对应的一端。
其中，公式y＝T-(x 2-B 2)/2B的获得方法是：设定门体转动轴心在XY坐标系上的坐标为(x,y)，其中，x表示门体转动轴心的横坐标，y表示门体转动轴心的纵坐标。假设门体2的门体转动轴心到N点的距离为R 2，且轴心到后边的距离为C，则门体2在转动过程中，N点在以轴心(x,y)为圆心半径为R 2的圆上运动，为了避免门体2与箱体1干涉，则要保证N点不与箱体1干涉，因此需要满足以下条件：R 2-C≤B，y＝T-C且x 2+C 2＝R 2 2，取R 2-C＝B，则经过换算可得：由此可得：x 2+C 2＝(C+B) 2，分解公式可得：C＝(x 2-B 2)/2B，将其代入y＝T-C可得公式y＝T-(x 2-B 2)/2B。
可以理解的是，在R 2-C＝B时，门体2转动过程中，门体2上的N点与箱体1相切。
假设门体2的厚度值T和第二间隙B为固定值，那么根据公式y＝T-(x 2-B 2)/2B可以绘制出图8所示的第二轨迹线F。若圆心为第二轨迹线F中各个点，以第二轨迹线F的点到N点的距离作为半径，则通过N点的圆都会与箱体1相切，即，在所述长轴孔2321位于所述第二轨迹线F上时，门体2转动过程中，所述门体2上的N点与箱体1相切。结合图9所示，而若圆心处于第二轨迹线F靠近所述枢转侧21的一侧的某一点时，通过N点的圆则会与箱体1之间有间隙，即，在所述长轴孔2321位于所述第二轨迹线F靠近所述枢转侧21的一侧时，门体2转动过程中，所述N点与所述箱体1之间有间隙。而若圆心处于第二轨迹线F远离所述枢转侧21的一侧的某一点时，通过N点的圆则会与箱体1之间有重叠，即，在所述门体转动轴心位于所述第二轨迹线F远离所述枢转侧21的一侧时，门体2转动过程中，所述N点与所述箱体1之间有干涉。因而，在所述门体转动轴心位于由所述第二轨迹线靠近枢转侧21的一侧限定的目标区域内时，门体2的N点与箱体1相切或有间隙，不会与所述箱体1干涉。故，确定所述目标区域进一步位于所述第二轨迹线靠近所述枢转侧21的一侧，以使门体2转动过程中，所述门体2与橱柜4以及箱体1之间均无干涉。
进一步地，所述目标区域位于第三轨迹线远离所述枢转侧21的一侧，在所述门体转动轴心位于所述第三轨迹线上时，所述门体2的实际最大开门角度等于所述预设最大开门角度。在所述门体转动轴心位于所述第三轨迹线远离所述枢转侧21的一侧时，所述门体2的实际最大开门角度大于所述预设最大开门角度；在所述门体转动轴心位于所述第三轨迹线靠近所述枢转侧21的一侧时，所述门体2的实际最大开门角度小于所述预设最大开门角度。从而，限定所述目标区域同时位于所述第三轨迹线远离所述枢转侧21的一侧，以使所述门体2的实际最大开门角度不小于所述预设最大开门角度。
可以理解的是，技术人员能够根据最终确定的门体转动轴心与第三轨迹线的位置关系，知晓最终的门体2的实际最大开门角度与预设最大开门角度的大小关系。对于本实施方式中的嵌入式冰箱而言，需求门体2的实际最大开门角度不小于最大开门角度，故，将目标区域限定为位于所述第三轨迹线远离所述枢转侧21的一侧。
进一步地，第三轨迹线的拟合方法包括如下步骤：
以处于关闭状态下的所述门体2的前壁22与门体2的铰链安装侧23的第一交线为X轴，以处于关闭状态下的所述门体2的枢转侧21与门体2的铰链安装侧23的第二交线为Y轴，并以所述X轴和所述Y轴的交点作为原点O，从而构建XY坐标系；
按照公式x＝y*tanV/2-A在所述XY坐标系内绘制所述第三轨迹线，其中，V表示所述预设最大开门角度，A表示门体2处于关闭状态时所述门体2的枢转侧21与橱柜4之间的第一间隙。
进一步地，公式x＝y*tanV/2-A中y的范围0≤y≤T，其中，T表示所述门体2的厚度值。以使确定出的所述目标区域位于门体2的厚度值范围内。当然，并不以此为限，在所述门体 转动轴心设置于门体2外部的实施方式中，也可以适应性扩大所述y的取值范围，如-T/2≤y≤T。
优选地，公式x＝y*tanV/2-A中，在A＝3时，0≤y≤T/4；在A＝4时，0≤y≤3T/10；在A＝6时，0≤y≤2T/5；在A＝10时，0≤y≤T/2；在A＝18时，0≤y≤3T/5。
在拟合出所述第三轨迹线后，所述第三轨迹线将处于关闭状态的所述门体2的铰链安装侧23分为两个区域，以位于所述第三轨迹线远离所述枢转侧21的一侧的区域为目标区域。
具体地，该公式x＝y*tanV/2-A的获取方法是：设定门体转动轴心在XY坐标系上的坐标为(x,y)，其中，x表示门体转动轴心的横坐标，y表示门体转动轴心的纵坐标。如图10所示，假设V为预设最大开门角度，橱柜4具有与原点在同一水平线上的D点，以门体转动轴心为圆点，门体转动轴心到D点的距离为半径画圆，该圆与门体2处于关闭状态时的铰链安装侧23的前边的交点为E点，则门体转动轴心与D点连线与门体转动轴心与E点连线之间的夹角即为门体2转过的角度V，另外由于处于关闭状态下的门体2的前壁22与橱柜4的前端相齐平，即D点与E点处于同一条水平线上，所以从圆心做一条垂直于门体2的前壁22线可以平分角度V，即V＝2W，且tanW＝(x+A)/y，分解公式可得x＝y*tanV/2-A。
假设门体2的厚度值T和第一间隙A为固定值，则根据上述求解的公式及y的范围0≤y≤T可以绘制出如图11所示的第三轨迹线G，可以得出其为一直线，在门体转动轴心位于第三轨迹线G上时，门体2的实际最大开门角度等于V，位于第三轨迹线G远离所述枢转侧21的一侧时门体2的实际最大开门角度大于V，位于第三轨迹线G靠近所述枢转侧21的一侧时门体2的实际最大开门角度小于V。
于一具体实施方式中，如图11所示，所述第三轨迹线G与第一轨迹线E、第二轨迹线F共同限定出所述目标区域。此时，所述目标区域的边界线包括第一轨迹E、第二轨迹线F以及第三轨迹线G。
在所述长轴孔2321设置于由所述第三轨迹线G与第一轨迹线E、第二轨迹线F共同限定出所述目标区域内或者该目标区域对应的边界线上时，门体2转动过程中，所述门体2与所述橱柜4、箱体1均不会产生干涉，且门体2的实际最大开门角度不小于预设最大开门角度。
当然，并不以此为限，于其他实施方式中，所述第三轨迹线也可单独或者与第一轨迹线或第二轨迹线共同限定出所述目标区域。
进一步地，所述目标区域位于第四轨迹线靠近所述枢转侧21的一侧，在所述门体转动轴心位于所述第四轨迹线上时，所述门体2转动至90°时所述门体2的前壁22与所述橱柜4之间的第三间隙等于门体2处于关闭状态时所述门体2的枢转侧21与橱柜4之间的第一间隙，即，门体2不会内移，从而不会影响用户取放物品；在所述门体转动轴心位于所述第四轨迹线靠近所述枢转侧21的一侧时，所述门体2转动至90°时所述第三间隙小于所述第一间隙，即，所述门体2转动至90°时会外移，有利于用户取放物品；在所述门体转动轴心位于所述第四轨迹线上远离所述枢转侧21的一侧时，所述门体2转动至90°时所述第三间隙大于所述第一间隙，即，所述门体2转动至90°时会内移，此时，所述门体2会遮蔽部分储物间室的储藏空间，影响用户取放物品。故，本发明中，将所述目标区域确定为位于所述第四轨迹线靠近所述枢转侧21的一侧，从而，门体2转动至90°后，不会遮蔽储物空间，不会影响用户取放物品。
具体地，所述第四轨迹线的拟合方法包括如下步骤：
以处于关闭状态下的所述门体2的前壁22与门体2的铰链安装侧23的第一交线为X 轴，以处于关闭状态下的所述门体2的枢转侧21与门体2的铰链安装侧23的第二交线为Y轴，并以所述X轴和所述Y轴的交点作为原点O，从而构建XY坐标系；
如图12所示，按照公式x＝y在所述XY坐标系内绘制第四轨迹线H。
进一步地，公式x＝y的获取方法是：设定门体转动轴心在XY坐标系上的坐标为(x,y)，其中，x表示门体转动轴心的横坐标，y表示门体转动轴心的纵坐标。假设x≠y。可以理解的是，如图2所示，在门体2处于关闭状态时，门体2与橱柜4之间的间隙为第一间隙A，如图13所示，在门体2转动90°时，门体2与橱柜4之间的间隙变成第三间隙A+a。若需要门体2转动后门体2与橱柜4之间的间隙不变，则需要a＝0，即x＝y。
于一具体实施方式中，按照x＝y的公式可以确定出门体转动轴心在处于关闭状态的门体2的铰链安装侧23上的第四轨迹线H，将门体转动轴心选择在该第四轨迹线H上或选择在该第四轨迹线H上移动，则可以保证门体2转动至90°时门体2与橱柜4之间的间隙不变，从而不会影响用户取物。
于图12所示的一具体实施方式中，所述第四轨迹线H与第一轨迹线E、第二轨迹线F、第三轨迹线G共同限定出目标区域，此时，请参图12所示，所述目标区域的边界线包括第三轨迹线G以及第四轨迹线H。
如图12所示，在所述门体转动轴心位于所述目标区域内或者目标区域对应的边界线上时，所述门体2转动过程中，所述门体2的前壁22位于所述枢转侧21的一端与所述橱柜4之间具有间隙，所述门体2的后壁位于所述枢转侧21的一端与所述箱体1之间具有间隙，所述门体2的实际最大开门角度不小于所述预设最大开门角度，所述门体2转动至90°时不会内移。
当然，并不以此为限，于其他实施方式中，所述第四轨迹线H也可以单独限定出所述目标区域；或者所述第四轨迹线H与所述第一轨迹线E、第二轨迹线F、第三轨迹线G中的至少一个组合限定出所述目标区域。
可以理解的是，本领域技术人员可以根据实际需要进对上述的第一轨迹线E、第二轨迹线F、第三轨迹线G、第四轨迹线H进行选择。从而，本领域技术人员在对长轴孔2321进行调节时可以知晓如何调节以及调节区域，给本领域技术人员提供了理论基础支持。
综上所述，本发明中的冰箱，通过设置止挡筋34以及与所述止挡筋34相配合的定位槽233的配合结构，用以将所述铰链轴32限制于所述第一端或者使所述铰链轴32自第二端移动至第一端。代替现有的弹性机构，能够避免出现因为弹性机构失效导致的机构失效，进一步提高门体2的可靠性以及稳定性。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
