Description

冰箱 技术领域
本申请涉及制冷装置领域，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。

具体地，当所述冰箱的右侧设置所述铰链板2时，所述第一方向即为从左向右的方向，所述第二方向即为从右向左的方向。当所述冰箱的左侧设置所述铰链板2时，所述第一方向即为从右向左的方向，所述第二方向即为从左向右的方向。
所述铰链板2与所述门体3中的一个上设有凸轮结构35、另一个上设有与所述凸轮结构35的轮廓曲线相配合的引导件22；在所述门体3转动的过程中，所述引导件22沿所述轮廓曲线移动，带动所述铰链轴21沿所述长轴孔31移动使所述门体3平移。在门体3旋转打开的同时，可以根据需求通过调节所述长轴孔31的延伸方向控制门体3的平移方向以及平移距离，从而使所述冰箱能够适应多种场景需求，如嵌入式场景。
也就是说，所述铰链轴21、长轴孔31、凸轮结构35、引导件22的分布位置可以包含多种情况。在第一示例中，所述铰链轴21以及引导件22设置于所述铰链板2上，所述长轴孔31以及凸轮结构35设置于所述门体3上，此时，所述凸轮结构35固定于所述门体3的铰链安装侧33上，所述长轴孔31贯穿所述凸轮结构35，即，所述长轴孔31同时位于所述凸轮结构35以及所述门体3上；在第二示例中，所述铰链轴21以及引导件22设置于所述门体3上，所述长轴孔31以及凸轮结构35设置于所述铰链板2上，此时，长轴孔31同样贯穿所述凸轮结构35；在第三示例中，所述铰链轴21以及所述凸轮机构设于所述铰链板2上，所述长轴孔31以及所述引导件22设置于所述门体3上，此时，所述铰链轴21可固定于所述凸轮机构上；在第四示例中，所述铰链轴21以及所述凸轮机构设于所述门体3上，所述长轴孔31以及所述引导件22设置于所述铰链板2上，此时，所述铰链轴21可固定于所述凸轮机构上。
这里，以第一示例为例，即，所述铰链轴21以及引导件22设置于所述铰链板2上，所述长轴孔31以及凸轮结构35设置于所述门体3上。
于本申请第一实施方式中，所述引导件22为固定的引导柱，通过所述引导柱沿所述凸轮结构35的轮廓曲线移动，带动所述铰链轴21于所述长轴孔31内移动，以带动所述门体3在转动的同时平移。
于本申请第二实施方式中，所述引导件包括转轴、套设于所述转轴上的滚轮，所述滚轮与所述凸轮结构35相配合。以减少所述引导件沿所述凸轮结构35移动时所述引导件与所述凸轮结构35之间的摩擦，有利于所述引导件与所述凸轮结构35之间的配合，且能够降低噪音。
所述第二实施方式与第一实施方式除上述区别外，其他均相同，于此，不再赘述。
进一步地，基于所述第一示例，所述门体3上与所述凸轮结构35的轮廓曲线相对应的位置处凹设有让位槽4，所述让位槽4的形状与所述轮廓曲线相同。所述引导件22具有与所述让位槽4相配合的延伸段。一方面，在安装所述门体3时，需要调节所述门体3的高度，若门体高度调节过大，易导致所述引导件22与所述凸轮结构35相脱离，从而，设置所述延 伸段能够保证所述引导件22始终与所述凸轮结构35相配合，保证门体3上下调节时所述引导件22以及凸轮结构35的配合结构的可靠性；另一方面，所述延伸段与所述让位槽4配合也能够使所述引导件22始终保持于所述凸轮结构35的轮廓曲线上，增强所述门体3平移的稳定性。
具体地，所述延伸段设于所述引导件22靠近所述门体3的一端。
可以理解的是，在所述凸轮结构35设置于所述铰链板2的实施方式中，所述让位槽4设于所述铰链板2上。
进一步地，所述长轴孔31包括相对的第一端311、第二端312，在所述门体3处于关闭状态时，所述铰链轴21位于所述第一端311。
所述轮廓曲线具有起始位置、终端位置、位于所述起始位置与所述终端位置之间的第一段351，在所述门体3处于关闭状态时，所述引导件22位于所述起始位置。在门体3旋转打开的过程中，所述引导件22自所述起始位置沿所述轮廓曲线向终端位置移动。
结合图3-图4所示，所述第一段351设置为在所述门体3打开至第一预设角度时，所述引导件22沿所述第一段351朝向所述第一段351靠近所述终端位置的一端移动，使所述铰链轴21自所述第一端311向所述第二端312移动，直至所述门体3打开至第二预设角度，此时，所述铰链轴21移动至所述第二端312。
具体地，所述第一段351呈弧形，且沿所述起始位置向终端位置的方向，所述第一段351逐渐远离所述长轴孔31，从而，在所述引导件22沿所述第一段351向所述第一段351靠近所述终端位置的一端移动时能够带动所述铰链轴21向第二端312移动。
于一具体实施方式中，基于所述第一示例，所述长轴孔31的延伸方向与所述门体3所在的平面相垂直，且所述第二端312位于所述第一端311远离所述门体3的前壁32的一侧，即，所述第一端311位于所述第二端312的前侧。在门体3的打开角度位于0°ˉ90°之间时，所述长轴孔31的延伸方向与所述第一方向之间的夹角逐渐减小，从而，在所述门体3的打开角度介于0°ˉ90°之间时，所述门体3平移使所述铰链轴21自第一端311移动至第二端312时，所述门体3在朝向所述第一方向移动的同时朝远离所述箱体1的方向移动。一方面，使所述门体3沿第一方向远离所述箱体1，可使得所述门体3尽量朝第一方向远离箱体1，保证所述门体3的开度，避免门体3遮蔽箱体1内的储物间室或者箱体1内的抽屉等受门体3干涉而无法打开，便于用户取放物品；另一方面，所述门体3朝远离所述箱体1的方向移动，增大所述门体3与箱体1之间的距离，能够防止门体3打开过程中，所述门体3的后壁与箱体1之间干涉，同时，对于嵌入式冰箱而言，能够使所述门体3的前壁32位于所述枢转端34的一端向前突伸出所述橱柜6的前端，能够减少门体3转动过程中所述门体3与所述橱柜6之间的干涉。当然，并不以此为限，可以理解的是，可以根据具体需求调节所述长轴孔31的延伸方向以控制门体3的平移方向。
具体地，于一具体实施方式中，所述第二预设角度为90°。当然，并不以此为限。
进一步地，所述门体3的运动轨迹设置为：在所述门体3自关闭状态打开至第一预设角度时，所述门体3原地转动；在所述门体3打开至第一预设角度且继续旋转打开时，所述引导件22沿所述第一段351朝向所述第一段351靠近所述终端位置的一端移动，使所述铰链轴21自所述第一端311向所述第二端312移动，使所述门体3向第一方向同时向远离所述箱体1的方向移动；在所述门体3打开至所述第二预设角度并继续打开时，所述铰链轴21自所述第二端312向所述第一端311移动，使所述门体3向所述第二方向移动，以进一步增大所述门体3的开度至所述门体3打开至第三预设角度，便于用户取放物品。当然，并不以此为限。
可知的是，在门体3处于关闭状态时，门体3上的门封紧密吸附于箱体1上，从而，在门体3自关闭状态打开时，先使门体3原地转动第一预设角度，能够使所述门封先脱离所述箱体1，以防门封发生变形损坏，影响门体3后续的密封性能。对应的，在关门至最后阶段，门体3原地转动至关闭，同样能够减少门封的变形，有利于门体3的顺利关闭。
同时，对于具有翻转梁的冰箱，门体3自关闭状态打开时先原地转动，能够使翻转梁翻转并脱离箱体1上的导向结构，使后续门体3能够继续旋转打开。对应的，在关门至最后阶段，门体3原地转动至关闭的过程中，能够使翻转梁在箱体1上的导向结构的引导下翻转至遮蔽左右门体3之间的缝隙。
于一具体实施方式中，所述第一预设角度介于30°ˉ60°之间。当然，并不以此为限。
进一步地，所述冰箱还包括弹性机构5，所述弹性机构5的自由端连接于所述铰链轴21上，所述弹性机构5用于在所述门体3自关闭状态打开至所述第一预设角度时限制所述铰链轴21沿所述长轴孔31移动，即，使所述铰链轴21保持在所述第一端311，从而，使所述门体3原地转动。同时，所述弹性机构5用于在所述门体3自第二预设角度继续转动时，驱动所述铰链轴21自所述第二端312向所述第一端311移动，以使所述门体3转动的同时向所述第二方向平移。
具体地，在所述长轴孔31设置于所述门体3上时，所述弹性机构5固定于所述门体3上，以使所述弹性机构5能够作用于所述铰链轴21，且使所述弹性机构5对所述铰链轴21的限位作用不受开关门体3的影响。同理，在所述长轴孔31设置于所述铰链板2上时，所述弹性机构5固定于所述铰链板2上，以使所述弹性机构5能够作用于所述铰链轴21，且使所述弹性机构5对所述铰链轴21的限位作用不受开关门体3的影响。
于一具体实施方式中，所述弹性机构5包括与所述铰链轴21相连接的滑块51、与所述滑块51相连接的弹簧52。在所述门体3自关闭状态转动至所述第一预设角度的过程中，所述弹簧52使所述铰链轴21保持在所述第一端311。在所述门体3自第一预设角度旋转打开至第二预设角度的过程中，所述铰链轴21向第二端312移动，所述弹簧52处于压缩状态。在所述门体3自第二预设角度继续打开时，在所述弹簧52的弹性回复力的作用下，驱动所述铰链轴21自第二端312向所述第一端311移动。
进一步地，结合图2-图3所示，所述轮廓曲线还具有连通所述起始位置与所述第一段351的第二段352，所述第二段352为以所述第一端311为圆心的圆弧。在所述门体3由关闭状态打开至第一预设角度的过程中，所述引导件22以所述铰链轴21为圆心并沿所述第二段352移动，此时，在所述弹性机构5的协同作用下，所述铰链轴21保持在所述第一端311，从而使所述门体3能够原地转动预设角度。
可以理解的是，所述第二段352的长度可根据所述门体3需要原地转动的角度来确定。同时，通过设置与所述引导件22相配合的第二段，能够进一步限位所述铰链轴21，使所述门体3打开至所述第一预设角度的过程中，所述铰链轴21保持在所述第一端311。
进一步地，结合图4-图5所示，所述轮廓曲线还具有连通所述第一段351与所述终端位置的第三段353，沿所述起始位置向终端位置的方向，所述第三段353逐渐靠近所述长轴孔31。在所述门体3打开至所述第二预设角度并继续打开时，所述引导件22在所述第三段353内并朝向所述第三段353靠近所述终端位置的一端移动，在所述弹性机构5的协同作用下，带动所述铰链轴21自第二端312向第一端311移动，所述门体3朝向与所述第一方向相反的第二方向移动。
可以理解的是，通过设置所述第三段353，从而，在所述弹性机构5驱动所述铰链轴21自第二端312向第一端311移动时，能够使所述铰链轴21缓慢向第一端311移动，增强所述门体3平移的平稳性，且降低噪音，防止铰链轴21与长轴孔31的孔壁碰撞导致损坏。
综上所述，本申请中的冰箱，通过设置凸轮结构35以及与所述凸轮结构35的轮廓曲线相配合的引导件22，在门体3旋转打开过程中，所述引导件22与所述轮廓曲线相配合引导门体3同步平移，使所述冰箱能够适应于多个场景，增强所述冰箱的通用性，且结构简单。
