技术领域
本申请涉及低温存储技术领域，例如涉及一种冰箱。
背景技术
冰箱的门如果关闭不严实，会导致冷箱漏冷，不仅会造成额外的能量消耗，而且有可能造成存储于冰箱中的物品变质，给用户带来极大的不便。
为了提高冰箱的密封性，相关技术中公开了一种冰箱门体，通过在门体上固定主门磁铁，箱体上安装侧板，当冰箱门体距离箱体距离很小的情况下，通过主门磁铁和侧板的相互吸引原理，消除彼此之间的间隙，以解决冰箱门体关闭不严的问题。通过在冰箱门体上安装固定减震座，防止因主门磁铁与侧板相互吸引力较大而导致的门体震动，起到缓冲减震的作用。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
利用磁铁的吸引力可以提高冰箱门的密封效果，但是随着冰箱门体与箱体之间距离的减小，磁铁的吸引力会成倍增加，即使设置减震座关闭冰箱门时仍会产生较大的振动并发出较大的噪音，用户体验有待进一步提高。

结合图1-17所示，本公开实施例提供一种冰箱，包括减震装置200，设置于门框114和冰箱门其中的一个，冰箱门在关闭状态下减震装置200位于冰箱门与门框114之间；其中，减震装置200包括壳体210、活塞220、受力杆240和活塞弹簧250，其中，壳体210，构造有储液腔，储液腔的第一端开设有传动孔；活塞220，滑动设置于储液腔，活塞220将储液腔分隔为第一腔体223和第二腔体224，活塞220开设有导通孔221；受力杆240，第一端连接于活塞220，第二端穿过传动孔向外伸出，受力杆240与传动孔滑动密封连接，在冰箱门关闭的过程中，受力杆240在外力作用下驱动活塞220从第一位置移动至第二位置，第二腔体224中的液体通过导通孔221流向第一腔体223；活塞弹簧250，设置于储液腔的第二端与活塞220之间，受力杆240受到的外力消失后活塞弹簧250驱动活塞220从第二位置回到第一位置，第一腔体223中的液体通过导通孔221流向第二腔体224。
在本公开实施例中，冰箱门在关闭状态下贴合于门框114，减震装置200位于冰箱门与门框114之间。在冰箱门关闭的过程中，冰箱门的动能被减震装置200吸收，从而避免冰箱门与门框114接触时产生振动和噪音。
减震装置200的壳体210为密闭壳体210，内部构造有柱状储液腔。活塞220滑动设置于壳体210以将壳体210内部的空间分隔第一腔体223和第二腔体224。活塞220开设有导通孔221，以使第一腔体223和第二腔体224连通。壳体210的第一端开设有传动孔，受力杆240与传动孔滑动密封连接。滑动密封连接是指受力杆240可以在传动孔内滑动，在滑动的过程中与传动孔的内圈贴合，第二腔体224中充注的工质不会通过受力杆240与传动孔之间的间隙泄露。作为一种可选实施形式，减震装置200还包括密封圈，密封圈为弹性材料，密封圈的端面贴紧受力杆240的第一端向内的以外，内圈与传动轴同轴。受力杆240穿过密封圈且与密封圈过盈配合。
受力杆240用于将减震装置200受到的力传递至活塞220。当减震装置200安装于门框114时，在冰箱门关闭的过程中，冰箱门在与门框114接触之前首先与受力杆240接触。受力杆240受力后驱 动活塞220从第一位置移动至第二位置，移动方向为自储液腔的第一端向储液腔的第二端移动。第一腔体223位于活塞220与储液腔的第一端之间，第二腔体224位于活塞220与储液腔的第二端之间。在活塞220移动的过程中，第一腔体223容积增大压力减小，第二腔体224容积减小压力增大。储液腔中充注有液体，第二腔体224中的液体在压力差的作用下通过导通孔221流向第一腔体223。在液体通过导通孔221流动的过程中，冰箱门的动能被转化为液体流动的内能被耗散，从而使冰箱门可以缓慢地关闭，减小冰箱门与门框114接触时引起的振动和噪音。在活塞220移动的过程中，活塞弹簧250变形也会吸收一部分能量。
在打开冰箱门的过程中，受力杆240收到的外力消失，活塞弹簧250驱动活塞220从第二位置向第一位置移动，移动方向为自储液腔的第二端向储液腔的第一端。在这个过程中，第一腔体223容积减小压力增大，第二腔体224容积增大压力减小。第一腔体223中的液体在压力差的作用下通过导通孔221流向第二腔体224。活塞220回到第一位置时，受力杆240向外伸出，为下次关闭冰箱门时的减震做好准备。
使用本公开实施例提供的冰箱，在关闭冰箱门的过程中，活塞220的移动速度成倍地转化为导通孔221内液体的流动速度，然后转化为储液腔内液体的内能，可以有效降低冰箱门关闭时的振动和噪声；受力杆240受力的大小表现为导通孔221内液体的流速，而导通孔221的截面积远小于活塞220的截面积，在用户观察视角，冰箱门以不同的速度关闭时活塞220以及受力杆240的移动速度不会发生太大变化。该种形式的减震装置200可以自适应低提供合适的阻尼，使冰箱门可以缓慢关闭并贴紧门框114进行密封；
可选地，活塞220还开设有安装孔222，减震装置200还包括单向阀230，设置于安装孔222，单向阀230的导通方向为自第一腔体223至第二腔体224。
在冰箱门关闭的过程中，活塞220在受力杆240的驱动力从储液腔的第一端向储液腔的第二端移动。单向阀230处于截止状态，第二腔体224中的液体仅通过导通孔221流向第一腔体223。通过导通孔221的节流提高了流经导通孔221的液体的流速，从而使机械能转化为液体的动能，最终通过液体分子的无序流动成为液体的内能。
在打开冰箱门的过程中，活塞220在活塞弹簧250的驱动下从储液腔的第二端向储液腔的一端移动。单向阀230处于导通状态，第一腔体223中的液体通过单向阀230和导通孔221流向第二腔体224。与仅通过导通孔221流动的形式相比，液体流动的导通截面积增大，液体流动阻力减小，活塞220移动阻力减小，活塞220可以快速地从第二位置回到第一位置。采用这样的设置形式，在用户短暂打开冰箱门的过程中减震装置200可以快速复位，为关闭冰箱门时的减震吸能做好准备，方便了用户使用。
可选地，单向阀230包括铰链轴231、和翻板232，其中，铰链轴231，设置于安装孔222；翻板232，转动设置于铰链轴231、且位于活塞220的一侧，液体从第一腔体223向第二腔体224流动时，翻板232在液体压力作用下触压于活塞220从而封堵安装孔222，液体从第二腔体224向第一腔体223流动时翻板232在液体压力作用下翻转从而使安装孔222处于导通状态。
翻板232围绕铰链轴231转动，翻板232位于活塞220靠近储液腔的第一端的一面，液体从第一腔体223向第二腔体224流动时，翻板232在第一腔体223和第二腔体224的压力差的作用下更紧密地贴合于活塞220，从而实现截止功能。液体从第二腔体224向第一腔体223流动时，翻板232在第一腔体223和第二腔体224之间的压力差的作用下翻转，从而使安装孔222处于导通状态。采用这 样的设置形式，单向阀230的结构简单成本较低；将安装孔222作为单向阀230的导通孔221，以较小的体积提供较大的导通截面积。
可选地，储液腔横向设置，活塞220横向滑动，安装孔222位于竖向的平面内，在初始状态下，翻板232在自身重力作用下悬垂贴紧活塞220，以封堵安装孔222。
液体从第一腔体223向第二腔体224流动时，翻板232可以在液体压力的作用下翻转。液体从第二腔体224向第一腔体223流动时，活塞220对翻板232的翻转进行了限位，翻板232被液体压力压紧在活塞220的端面，从而封堵安装孔222，实现反向截止功能。采用这样的设置形式，单向阀230工作可靠且成本较低。
可选地，单向阀230还包括翻板弹簧，用于使翻板232在初始状态下封堵安装孔222。
设置有翻板弹簧可以使翻板232保持在初始位置，更好地实现反向截止功能。使用翻板弹簧可以使单向阀230的安装方向不受限制，使其可以应用于不同开门形式的冰箱。
可选地，受力杆240内部构造有第三腔体241，受力杆240的第一端开设有敞口以使第三腔体241连通导通孔221和安装孔222，第三腔体241的侧边开设有连通第一腔体223的连通孔242，第一腔体223与第二腔体224通过第三腔体241连通。
受力杆240为中空结构，内部构造有第三腔体241。受力杆240的第二端为顶端，可以向外伸出传动孔。受力杆240为柱状，顶端封闭，第一端敞口。第一端连接于活塞220，活塞220开设的导通孔221和安装孔222均与受力杆240第一端的敞口对应。第三腔体241中的液体可以通过导通孔221和连通孔242穿过活塞220进入第二腔体224中。第二腔体224中的液体通过导通孔221或安装孔222后也就穿过活塞220进入了第三腔体241中。
在一种可选实施情形中，受力杆240与活塞220一体成型，受力杆240底部的敞口即为活塞220开设有的孔，活塞220开设的孔设置有挡片，挡片遮挡受力杆240底部的敞口的一部分。导通孔221开设于挡片。受力杆240底部的敞口未被挡片遮挡的部分为安装孔222。翻板232封堵安装孔222时贴紧挡片。
第三腔体241的侧边开设有连通孔242，以使第三腔体241与第一腔体223连通。活塞220在第一位置和第二位置之间滑动时，连通孔242均不会超出传动孔。
活塞220从第一位置向第二位置移动时，第二腔体224中的液体通过导通孔221进入第三腔体241，第三腔体241中的液体通过连通孔242进入第一腔体223；活塞220从第二位置向第一位置移动时，第一腔体223中的液体通过连通孔242进入第三腔体241，第三腔体241中的液体通过导通孔221的单向阀230进入第二腔体224。
受力杆240内部为中空结构，可以增大减震装置200储存的液体的量，从而提高减震装置200的减震吸能能力。而由于受力杆240内部为中空结构，受力杆240可以连接于活塞220的中心位置，导通孔221和安装孔222也可以开设于活塞220的中心位置，活塞220移动时受力均衡，不容易与储液腔的内部发生摩擦，这样可以提高减震装置200的使用寿命。在关闭冰箱门的过程中，第二腔体224中的液体要流经导通孔221和连通孔242，这样可以提高液体流动时的混乱程度，更好地将减震装置200受到的冲击转化为液体的内能。
可选地，受力杆240开设有多个连通孔242。
多个连通孔242可以提高液体在第一腔体223和第三腔体241之间的交换速度，有利于液体在第一腔体223和第二腔体224之间流动。尤其是在活塞220从第二位置向第一位置移动时，受力杆240 开设有多个连通孔242可以提高受力杆240的回弹速度。
可选地，冰箱还包括缓冲垫，对应于减震装置200设置于门框114和冰箱门其中的另一个，关闭冰箱门时缓冲垫与受力杆240的第二端接触以驱动减震装置200的活塞220移动。
在减震装置200设置于门框114的情况下，缓冲垫设置于冰箱门。在关闭冰箱门的过程中，缓冲垫与受力杆240的第二端接触，从而驱动活塞220从第一位置向第二位置移动。冰箱还设置有缓冲垫，可以进一步降低关闭时的噪音，减小关门时的冲击振动。
可选地，冰箱还包括箱体100，箱体100构造有第一容置空间，箱体100的侧边构造有与第一容置空间连通的第一敞口；冰箱门包括主冰箱门110和副冰箱门120，其中，主冰箱门110，可开合地设置于第一敞口，主冰箱门110内部构造有第二容置空间和与第二容置空间连通的第二敞口，第二敞口与第一敞口位于箱体100的同一侧面，门框114设置于第二敞口；副冰箱门120，可开合地设置于第二敞口，副冰箱门120设置有副门磁铁组140，副冰箱门120在关闭状态下贴合于门框114，主门磁铁组130与副门磁铁组140吸合；其中，减震装置200设置于副冰箱门120或门框114。

可选地，副门磁铁组140包括六块副门磁铁143，每相邻的两个副门磁铁143之间的角度为60°。主门磁铁组130包括六块主门磁铁133，每相邻的两个主门磁铁133之间的角度为60°。
主门磁铁组130和副门磁铁组140的磁铁数量相同，有利于的主门磁铁组130和副门磁铁组140之间更好地产生吸引力或排斥力。打开副冰箱门120时，驱动装置150驱动副门磁铁组140转动的角度为60°，既不会因为转动角度过大而有太长的驱动行程，也不会因为转动角度较小而要求较大的力矩。通过把手152带动副门磁铁组140转动时，转动60°符合人体工程力学，方便用户使用。
可选地，主冰箱门110和副冰箱门120通过同一把手打开，打开主冰箱门110所需的力小于主门磁铁组130与副门磁铁组140之间的吸引力。
用户在打开主冰箱门110时，直接向外拉动把手152。由于主门磁铁组130和副门磁铁组140之间牢固地吸合，拉动把手152既能打开主冰箱门110。用户打开副冰箱门120时，转动把手152，主门磁铁座131和副门磁铁组座141之间的吸引力变为排斥力副冰箱门120被弹开，用户向外拉动把手152即开打开副冰箱门120。采用这样的设置形式，主冰箱门110和副冰箱门120的开门动作比较清晰，使用同一个把手152即可通过不同的操作打开主冰箱门110或副冰箱门120，开门操作区分度比较高，方便用户使用。
