现有的嵌入式冰箱中的门体在转动过程中门体转动轴心不合适时，只能通过技术人员根据自己的经验去调节，调节时由于需要不断地在各个位置去尝试导致调节时长较长，并且极大可能无法调节到最佳位置。
有鉴于此，有必要提供一种新的嵌入式冰箱的门体转动轴心的确定方法及嵌入式冰箱以解决上述问题。

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9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。
在本发明的描述中，术语“上”、“下”、“前”、“后”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而不是要求本发明必须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。例如，在下面的描述中，图2中的下侧为前，上侧为后。
图1示出了根据本发明一个实施例的嵌入式冰箱的部分示意性立体图。图2示出了根据本发明一个实施例的嵌入式冰箱的示意性俯视图(去除铰链)，其中仅示出一侧的橱柜4，实际安装中，嵌入式冰箱是整个嵌入橱柜4中的。可以理解的是，嵌入式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，该嵌入式冰箱与现有技术中的冰箱结构保持一致，一般性地包括箱体1和与箱体1通过铰链3转动连接的门体2。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为嵌入式冰箱在嵌入橱柜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的上侧，即铰链3的一端是安装在该铰链安装侧23的，铰链3的另一端安装在冰箱的箱体1的上侧。该门体2的枢转侧21为门体2绕箱体1转动的一侧。
本发明提供一种嵌入式冰箱的门体转动轴心的确定方法，包括如下步骤：
获取所述门体2的预设最大开门角度；
拟合出第一轨迹线，在所述门体转动轴心位于所述第一轨迹线上时，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；
确定目标区域位于所述第一轨迹线远离所述枢转侧21的一侧，在门体2转动过程中，确定门体转动轴心位于所述目标区域内或者位于所述目标区域的边界线上。
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。
具体地，所述门体转动轴心可以为实体轴心也可以为虚拟轴心。如，在所述铰链3为单轴铰链时，所述门体转动轴心即为所述单轴铰链中的转轴的轴心，即为实体轴心。在所述铰链3为多轴铰链时，所述门体转动轴心即为由所述多轴铰链中的多轴限定出的虚拟轴心。
在所述第一轨迹线上调试所述门体转动轴心的位置时，门体2的实际最大开门角度等于预设最大开门角度，在所述第一轨迹线远离所述枢转侧21的一侧调试所述门体转动轴心的位置时，所述门体2的实际最大开门角度大于预设最大开门角度。在所述第一轨迹线靠近所述枢转侧21的一侧调试所述门体转动轴心时，所述门体2的实际最大开门角度小于预设最大开门角度。
本发明中，所述门体开度的需求为使得门体2的实际最大开门角度大于或等于预设最大开门角度，故，确定目标区域位于所述第一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一轨迹线的位置关系，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。
需要说明的是，上述的门体转动轴心位于所述目标区域内或者位于所述目标区域的边界线上可以理解为门体2转动过程中，所述门体转动轴心始终位于所述目标区域内的一个点上或者始终位于所述目标区域的边界线的一个点上；也可以理解为门体2转动过程中，所述门体转动轴心在所述目标区域和/或所述目标区域的边界线上移动。
进一步地，“拟合出第一轨迹线”具体包括如下步骤：
请参图4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，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一轨迹线，其中，V表示所述预设最大开门角度，A表示门体处于关闭状态时所述门体的枢转侧与橱柜之间的第一间隙。
进一步地，公式x＝y*tanV/2-A中y的范围0≤y≤T，其中，T表示所述门体的厚度值。以使确定出的所述目标区域位于处于关闭状态时的门体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；或者所述y的范围也可以设置为使所述目标区域位于处于关闭状态时的门体2的铰链安装侧23上，以便于铰链轴的设置。
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。
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3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可以绘制出如图4所示的第一轨迹线G，可以得出其为一直线，在门体转动轴心位于第一轨迹线G上时，门体2的实际最大开门角度等于所述预设最大开门角度，在门体转动轴心位于第一轨迹线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所述预设最大开门角，在门体转动轴心位于第一轨迹线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所述预设最大开门角。
进一步地，所述确定方法还包括如下步骤：
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6所示，按照公式x＝y在所述XY坐标系内绘制第二轨迹线H；在所述门体转动轴心位于所述第二轨迹线上时，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
确定所述目标区域同时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H上时，所述门体转动至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二轨迹线H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，更有利于用户取放物品；在所述门体转动轴心位于所述第二轨迹线H上远离所述枢转侧21的一侧时，所述门体转动至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，将所述目标区域进一步确定为位于所述第二轨迹线H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。
可以理解的是，可以根据是否需要门体2转动至90°时门体2与橱柜4之间的间隙不变来确定调试的区域以及调试方向。
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5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。
因此，若需要使得所述门体2转动至90°时所述门体2的所述前壁22与所述橱柜4之 间的第三间隙等于所述第一间隙，则需要在该第二轨迹线上寻找门体转动轴心或者需要使得门体转动轴心在所述第二轨迹线H上移动。
根据本发明实施例的方案，按照x＝y的公式可以确定出轴心在铰链安装侧23上的第二轨迹线H，将轴心选择在该第二轨迹线H上或选择在该第二轨迹线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。
此时，所述目标区域由所述第一轨迹线G以及第二轨迹线H共同限定，所述目标区域的边界线包括第一轨迹线G以及第二轨迹线H。
在所述门体转动轴心位于所述目标区域内时，所述门体2转动过程中，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，且所述门体2转动至90°时外移。
在所述门体转动轴心位于作为边界线的第一轨迹线G上时，所述门体2转动过程中，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，所述门体2转动至90°时外移。
在所述门体转动轴心位于作为边界线的第二轨迹线H上时，所述门体2转动过程中，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，所述门体2转动至90°时与所述橱柜4之间的间隙不变。
进一步地，所述确定方法还包括如下步骤：
拟合出第三轨迹线，在所述门体转动轴心位于所述第三轨迹线上时，门体2转动过程中，所述门体2的前壁22位于枢转侧21的一端与橱柜4相切；
确定目标区域位于所述第三轨迹线远离所述箱体1的一侧。
在所述门体转动轴心位于所述第三轨迹线远离所述箱体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之间具有间隙，即，可以保证门体2在转动过程中不干涉橱柜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或者目标区域的边界线上进行调试，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。
进一步地，上述的“拟合出第三轨迹线”具体包括如下步骤：
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x＝(y 2-A 2)/2A在所述XY坐标系内绘制出所述第一轨迹线，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。
进一步地，公式x＝(y2-A2)/2A中y的范围为：0≤y≤T，其中，T表示所述门体的厚度值。以使确定出的所述目标区域位于处于关闭状态时的门体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处于关闭状态时的门体2的铰链安装侧23上，以便于铰链轴的设置。
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R1，则门体2在转动过程中，原点在围绕轴心(x,y)同时半径为R1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R 1-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R1-x＝A时，门体2转动过程中，所述门体的前壁22位于枢转侧21的一端与橱柜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7所示的第三轨迹线E。若圆心为第三轨迹线E中各个点，则第三轨迹线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位于所述第三轨迹线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。而若圆心处于第三轨迹线E远离所述箱体1的一侧的某一点，则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位于所述第三轨迹线E远离所述箱体1的一侧时，门体2转动过程中，所述门体的前壁22位于枢转侧21的一端与橱柜4有间隙。因而，进一步限定所述目标区域位于所述第三轨迹线E远离所述箱体1的一侧，以使门体2转动过程中，不会与所述橱柜4干涉。
于图7所示的具体实施方式中，所述第三轨迹线E与所述第一轨迹线G、第二轨迹线H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线G、第二轨迹线H。在所述门体转动轴心位于所述目标区域内或者所述目标区域的边界线上时，能够保证所述门体2转动过程中，所述门体2不会与所述橱柜4相干涉，同时，保证所述门体2的实际最大开门角度不小于所述预设最大开门角度，且所述门体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，所述第三轨迹线E也可以与所述第一轨迹线G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线G以及第三轨迹线E。在所述门体转动轴心位于所述目标区域内或者所述目标区域的边界线上时，能够保证所述门体2转动过程中，所述门体2不会与所述橱柜4相干涉，同时，保证所述门体2的实际最大开门角度不小于所述预设最大开门角度。
进一步地，所述确定方法还包括如下步骤：
拟合出第四轨迹线，在所述门体转动轴心位于所述第四轨迹线上时，门体转动过程中，所述门体的后壁位于枢转侧的一端与所述箱体相切；
所述目标区域位于所述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靠近所述枢转侧21的一侧时，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，从而，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的一侧或者位于所述第四轨迹线上时，在门体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之间不会干涉。
进一步地，上述“拟合出第四轨迹线”具体包括如下步骤：
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四轨迹线，其中，B表示门体处于关闭状态时所述门体与所述箱体之间的第二间隙，T表示所述门体的厚度值。
进一步地，公式y＝T-(x 2-B 2)/2B中x的范围0≤x≤L，其中，L表示所述门体的宽度值。以使确定出的所述目标区域位于处于关闭状态时的门体的宽度值范围内。当然，并不以此为限，在所述门体转动轴心设置于门体外部的实施方式中，也可以适应性扩大所述x的取值范围。
具体地，如图2所示，所述门体2的铰链安装侧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的后壁位于所述枢转侧21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。如图7所示，假设门体2的门体转动轴心到N点的距离为R2，且轴心到后边的距离为C，则门体2在转动过程中，N点在围绕轴心(x,y)半径为R2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以及x的范围0≤x≤L可以绘制出图7所示的第四轨迹线F。若圆心为第四轨迹线F中各个点，以第四轨迹线F到点N的距离作为半径，则通过点N的圆都会与箱体1相切，即，在所述门体转动轴心位于所述第四轨迹线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。而若圆心处于第四轨迹线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，在所述门体转动轴心位于所述第四轨迹线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。而若圆心处于第四轨迹线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四轨迹线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，将所述目标区域进一步限定为位于所述第四轨迹线靠近枢转侧21的一侧，以使门体2转动过程中，所述门体2与所述箱体1之间无干涉。
如图7所示，所述第一轨迹线G与所述第二轨迹线H限定的目标区域位于所述第四轨迹线F限定的目标区域内，同时所述第一轨迹线G与所述第二轨迹线H限定的目标区域位于所述第三轨迹线E限定的目标区域内，即，在所述门体转动轴心位于由所述第一轨迹线G与所述第二轨迹线H或者第一轨迹线G、第二轨迹线H、第三轨迹线E共同限定的所述目标区域内或者盖目标区域的边界线上时，所述门体2转动过程中，能够满足不会与箱体1以及橱柜4相干涉，同时所述门体2的实际最大打开角度不小于所述预设最大打开角度，所述门体2打开至90°时，不会内移。故，在已经限定有第一轨迹线G以及第二轨迹线H限定的目标区域后，无需考虑所述第四轨迹线F。
基于上，所述第四轨迹线F可单独与所述第一轨迹线G共同限定所述目标区域，此时，所述目标区域的边界线包括所述第一轨迹线G以及第四轨迹线F。在所述门体2位于该目标区域内或者位于该目标区域的边界线上时，所述门体2的实际最大打开角度不小于所述预设最大打开角度，同时，所述门体2转动过程中，不会与所述箱体1之间产生干涉。
或者，所述第四轨迹线F可与所述第一轨迹线G以及第三轨迹线E共同限定所述目标 区域，此时，所述目标区域的边界线包括第四轨迹线F、第一轨迹线G以及第三轨迹线E。在所述门体2位于该目标区域内或者位于该目标区域的边界线上时，所述门体2的实际最大打开角度不小于所述预设最大打开角度，同时，所述门体2转动过程中，不会与所述箱体1以及橱柜4之间产生干涉。
在所述门体2在转动过程中，门体转动轴心始终位于由所述第一轨迹线以及第二轨迹线限定的所述目标区域内，从而，可以保证门体转动轴心设置的位置能够使得门体2在转动过程中既不干涉橱柜4也不干涉箱体1。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，请参图1-图2所示，本发明还提供一种嵌入式冰箱，嵌入所述橱柜4内。所述嵌入式冰箱包括箱体1、与所述箱体1通过铰链3转动连接的门体2，在开关门体2过程中，所述门体2绕门体转动轴心转动。所述门体转动轴心设置于目标区域内或者位于所述目标区域的边界线上。所述目标区域的确定方法由上述的门体转动轴心的位置确定方法进行确定，于此，不再一一赘述。
具体地，所述门体转动轴心可以为实体轴心也可以为虚拟轴心。如，在所述铰链3为单轴铰链时，所述门体转动轴心即为所述单轴铰链中的转轴的轴心，即为实体轴心。在所述铰链3为多轴铰链时，所述门体转动轴心即为由所述多轴铰链中的多轴限定出的虚拟轴心。
下面，以所述门体转动轴心为实体轴心为例，对若干具体需求下的实施方式中的嵌入式冰箱的门体转动轴心的确定方法进行阐述。
第一实施方式：
如图7所示，定义第一轨迹线G与第二轨迹线H的交点P1与原点之间的线段为第一线段。综合考虑，最终确定门体转动轴心为所述第一线段上的某一定点，或者所述门体转动轴心在所述第一线段上移动。此时，所述门体2的实际最大打开角度不小于所述预设最大打开角度，同时，所述门体2转动过程中，不会与所述箱体1以及橱柜4之间产生干涉，且，门体2打开至90°后，不会内移。
于一具体实施方式中，A＝4，V＝120°，可以求得P1点的坐标为(-5.46,5.46)，考虑到铰链轴的直径强度要求，设定铰链轴直径大于或等于6mm，另考虑铰链轴在门体2上的安装，最终选定P1点为轴心点，门体2绕P1点转动过程中与橱柜4、箱体1均无干涉，且最大开门角度为120°，同时，门体2打开至90°时不会内移。
第二实施方式：
本实施方式与第一实施方式的区别在于：如图8所示，该门体铰链装置3包括上铰链装置33和下铰链装置34。上铰链装置33和下铰链装置34各自具有铰链座31和铰链轴32。以下以上铰链装置33为例进行说明，本领域技术人员可知，下铰链装置34可以按照上铰链装置33在门体2和箱体1上的安装形式进行设计。
所述门体2的前壁22高于所述铰链3，以达到隐藏设置所述铰链3的目的。有利于所述嵌入式冰箱的整体外观效果。
具体地，该门体2的顶侧(即铰链安装侧23)所在位置高于箱体1的顶侧所在位置，且门体2顶侧的铰链安装侧23具有一凹槽231。该上铰链装置33的铰链座31横跨在箱体1的顶侧和该门体2的凹槽231处，以将上门体铰链装置3隐藏于门体2的后侧。
参见图8，该凹槽231贯穿门体2的枢转侧21、上侧的铰链安装侧23和后侧，也就是 说，该凹槽231并没有贯穿门体2的前侧22，在门体2处于关闭状态时，从前方观察冰箱时，无法看见该凹槽231，从而无法看到上门体铰链装置3，进而将上门体铰链装置3隐藏在该凹槽231内，保证了门体2的美观度。
该上铰链装置33的铰链座31可以构造成长方形，该长方形结构的一条长边与箱体1的顶侧外边缘对齐，且在门体2处于关闭状态时也与门体2的顶侧外边缘对齐。可以理解的是，由于该门体2的凹槽231并未贯穿门体2的前侧22，因此，该铰链座31位于所述枢转侧23的一侧具有如图9所示的避让部311，该避让部311可以在门体2打开至较大角度时，避让门体2的前壁22，以顺利将该铰链座31安装在箱体1和门体2的顶侧。
并且，该实施例中，为了避免上铰链装置33与门体2产生装配干涉，相较于第一实施方式，需要使铰链轴32更靠近所述箱体1。将铰链轴32设置于第三轨迹线E与第二轨迹线H的交点与交点P1之间的连线上。
于一具体示例中，若要同时满足门体2的实际最大开门角度不小于所述预设最大开门角度，可以选取门体转动轴心的坐标为(-11.59,9)。
第三实施方式：
本发明中的第三实施方式与第一实施方式的区别为：所述门体2为玻璃门体。更耐划伤，且玻璃门体花色多样，可以与家具等随意搭配。
因玻璃门体的前壁22为具有一定厚度的玻璃面板，同时固定所述玻璃门体的门体塑料饰条也需要有一定的壁厚，所述门体塑料饰条与玻璃面板之间还需要设置胶带或者热熔胶的粘结间隙。故，对于玻璃门体而言，铰链轴需要距离所述门体2的前壁22距离较大。此时，可以在由第三轨迹线E远离所述箱体1的一侧、第四轨迹线F朝向所述枢转侧21的一侧、第一轨迹线G远离所述枢转侧21的一侧、第二轨迹线H远离所述枢转侧21的一侧的重叠区域内或者在所述重叠区域中的第一轨迹线G上确定门体转动轴心的位置，如，可以选取门体转动轴心的坐标为(-15,11)。
综上所述，根据本发明中的门体转动轴心的位置确定方法可以确定出门体转动轴心的目标区域，从而，可以在确定的目标区域内进行调试，能够保证门体的实际最大开门角度不小于预设最大开门角度。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，本发明可以根据需要来确定调试的区域以及调试方向，从而避免在调试过程中反复出现无法打开至预设最大开门角度从而增加调试时间的现象。
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。
