Description

压缩机减震机构和冰箱 技术领域
本发明涉及一种压缩机减震机构，尤其涉及一种包括该压缩机减震机构的冰箱。
背景技术
压缩机是冰箱的动力源，也是冰箱最大的噪声源。压缩机噪声一部分透过壳体辐射出来，一部分通过管路震动传递，还有一部分通过减震脚垫作用至冰箱底板，通过底板震动辐射出来。现有冰箱压缩机隔震减震方案主要是搭载橡胶脚垫实现的，但橡胶脚垫无法完全将压缩机的震动与底板隔离，使得压缩机运行时，冰箱整体发出噪音以及伴随着抖动，当压缩机运转的震动超过了橡胶脚垫所能承受的一定范围时，震动沿着橡胶脚垫一直向下传递到底板上，抖动和噪音还将进一步增大。
以及，压缩机作为旋转机械，其震动不仅具有直线的震动，还有扭转的震动，橡胶脚垫对这些震动无法都具有很好的减震效果，冰箱持续发出的噪音及伴随着抖动，影响了用户的使用体验。
发明内容
为解决现有技术中的问题，本发明的目的在于提供一种减震效果好的压缩机减震机构、以及具备该减震机构的冰箱。
为实现上述发明目的，本发明一实施方式提供一种压缩机减震机构，所述减震机构包括减震脚垫，所述减震脚垫包括减震本体、以及形成与所述减震本体内部的减震腔，所述减震腔内填充液体，所述减震本体抵持于所述压缩机和压机仓的底板之间。
作为本发明的进一步改进，所述减震机构还包括固定于所述底板的导向柱，所述减震脚垫包括通孔，所述减震脚垫通过所述通孔套设于所述导向柱。
作为本发明的进一步改进，所述减震机构还包括止挡片，所述止挡片固定连接于所述导向柱，且设置于所述减震脚垫上方。
作为本发明的进一步改进，所述导向柱设置卡槽，所述止挡片卡设于所述卡槽内。
作为本发明的进一步改进，所述减震本体底部设置由下向上横截面逐渐增大的缓冲部，所述减震本体过盈配合于所述止挡片和所述底板之间。
作为本发明的进一步改进，所述通孔内设置限位凸起，所述限位凸起内部围出的孔的直径小于所述导向柱的直径。
作为本发明的进一步改进，所述减震腔环所述通孔周向设置。
作为本发明的进一步改进，所述减震本体包括工字型的槽体，所述压缩机包括压机本体和支撑所述压机本体的支撑板，所述支撑板上设置开孔，所述支撑板通过所述开孔插接于所述槽体内。
作为本发明的进一步改进，所述减震本体包括开口和用于封闭所述开口的熔融层，液体通过所述开口灌注于所述减震腔内，所述熔融层覆盖所述开口。
为实现上述发明目的之一，本发明一实施例提供了一种冰箱，所述冰箱包括上述的压缩机减震机构。
与现有技术相比，本发明具有以下有益效果：该减震机构的减震效果相对于现有的橡胶脚垫更好，来自压缩机的各方向不规则的震动传递到减震机构的减震脚垫上后，减震腔内的液体与减震本体获得的角动量弱于传统的橡胶脚垫，使其传递震动到底板上的能力减弱，在密闭的减震腔内填充的液体减弱了压缩机的震动，当压缩机的扭转震动传递到减震本体上后，内部的液体也影响减震机构进一步扭转震动，所以对压缩机的减震效果更好，且由于内部的液体不与外界其他器件接触，所以也不存在漏液的问题。

具体实施方式
以下将结合附图所示的具体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。
应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
本发明一实施例提供一种压缩机减震机构及应用该减震机构的冰箱，主要用于对冰箱内的压缩机产生的震动予以减震，进一步地减少了压缩机对外产生的噪音。
减震机构1设置在压机仓10内部，如图1和图2所示，为了清楚地表达本实施例中所描述的位置与方向，以设置在底部的压机仓10为例，即冰箱的压机仓10设置在冰箱的底部，本实施例中，定义底部即为冰箱的下方，减震机构1包括减震脚垫11，这样减震脚垫11的上方为压缩机3，下方为压机仓10的底板2，减震脚垫11承接来自其上方的震动，对压缩机3支撑的同时对其震动减震。
具体地，减震脚垫11包括减震本体111、以及形成与减震本体111内部的减震腔110，减震腔110为一密闭的空间，减震腔110内填充液体，减震本体111抵持于压缩机3和压机仓10的底板2之间，液体始终处于密封的减震腔110内部，也不与压缩机3等其他 部件接触，压缩机3和底板2仅与减震本体111接触。
本实施例的减震机构1相对于传统的橡胶脚垫具有更好的减震效果，在于内部的液体不会稳定地将震动传递到下方的底板2上，其原理类似于生鸡蛋在地上无法顺畅地旋转，而熟鸡蛋可以稳定旋转，由于生鸡蛋(减震本体111)内部是液体，对生鸡蛋(减震本体111)的运动形成了阻碍，生鸡蛋(减震本体111)不具有稳定的重心，力也无法在生鸡蛋(减震本体111)上沿着稳定的方向传递，而熟鸡蛋(橡胶脚垫)形成一个整体后，力的传递稳定。
或者说，在压缩机3将震动传递到减震机构1的位置时，其震动可以视为一个直线方向加一个旋转方向的叠加状态，在该方向上减震本体111虽然也会同步运动，但减震腔110内的液体不会，液体与减震本体111之间会产生速度的差异，而传统的橡胶脚垫相对于本实施例的减震机构1则同步转动，所以具有更大的角动量，震动传递得更为直接，底板2受到更大的震动，而本实施例的减震机构1减少了压缩机3的震动到底板2上的传递过程。
所以，基于上述论述，可以明确液体只需要完全灌装在减震腔110内即可，而无需与压缩机3的支撑脚接触，其作用的原理，不同于油缸内活塞的运动——即类似于闭门器那类靠挤压液压油实现减震，本实施例的液体在密闭的减震腔110内即可实现减震效果，同时还避免了液体的泄漏。
尤其是，本实施例的减震机构1应用于冰箱上的压缩机3，压缩机3作为旋转机械，其震动也包括了扭转震动，同上述生鸡蛋的例子，本实施例的减震本体111相当于鸡蛋的壳体，减震腔110内的液体相当于蛋液，相比于熟鸡蛋(现有技术的橡胶脚垫)，其对扭转震动的抵抗能力更强，扭转震动传递到减震脚垫11上使其获得的角动量更小，从而震动更小实现了更好的减震效果，该结构针对压缩机3的震动性质起到更有利的减震效果。
进一步地，如图3所示，减震机构1还包括固定于底板2的导向柱12，减震脚垫11包括通孔112，减震脚垫11通过通孔112套设于导向柱12。导向柱12起到导向作用，同时防止减震脚垫11因震动偏离设定位置，减震脚垫11从上向下套设在导向柱12上，压缩机3固定在减震脚垫11上，可以不与导向柱12发生接触。
更进一步地，减震机构1还包括止挡片13，止挡片13固定连接于导向柱12，且设置于减震脚垫11上方，具体的安装步骤，是先将减震脚垫11固定在压缩机3上，再通过其通孔112插入到底板2上的导向柱12上，再固定该止挡片13，防止压缩机3震动时带着减震脚垫11向上脱离导向柱12。
以及，导向柱12上设置卡槽121，止挡片13卡设于卡槽121内，如图3所示，当然也可以导向柱12上设置凸起，止挡片13卡接于该凸起。
如图3或图5所示，减震本体111底部设置由下向上横截面逐渐增大的缓冲部114，减震本体111过盈配合于止挡片13和底板2之间，该缓冲部114的剖视图可以理解为去除锥形部分的剩余锥形的空间，过盈配合时端部能有较大的挤压变形余量，在压缩机3进一 步向下压迫减震脚垫11时，能挤压变形的余量越来越小，从而装配得越来越紧，这样可以尽量减少缓冲部114以上的区域的变形，使上方的区域保持其设计的状态。
另外，通孔112内设置限位凸起115，限位凸起115内部围出的孔的直径小于导向柱12的直径，这样减震脚垫11牢固地插在导向柱12上，插入导向柱12时摩擦阻力减小，在静置状态时，减震脚垫11也在限位凸起115的位置上与导向柱12压迫更紧，其他位置较松，这样避免其震动时过多地传递到导向柱12上，同时又避免了与导向柱12之间产生松动。
以及，减震腔110环通孔112周向设置，减震腔110的横截面为圆环形，在各个方向均匀地减震。
进一步地，减震本体111包括工字型的槽体113，压缩机3包括压机本体和支撑所述压机本体的支撑板31，支撑板31上设置开孔，支撑板31通过开孔插接于槽体113内，槽体113下方的减震本体111的半径大于槽体113上方的减震本体111的半径，支撑板31插到槽体113内时，槽体113上方的减震本体111发生部分的变形，支撑板31通过开孔挤入到槽体113内，压缩机3通过支撑板31坐在槽体113上，槽体113下方即为填充了液体的减震腔110。
另外槽体113的上方还有部分的缺口，如图5所示，这样将压缩机3的支撑部31插入到槽体113时，缺口位置可以容纳部分的形变，使其易于插入，方便了装配。
减震腔110内的液体可以为油或水，优选地采用不易氧化的油。
进一步地，减震本体111包括开口和用于封闭开口的熔融层，液体通过开口灌注于减震腔110内，所述熔融层覆盖所述开口。生产时，先在减震腔110的缓冲部114位置设置开口，向减震腔110内灌注液体，灌注完成后，再以融入层封装该开口，使减震腔110内部形成密闭的空间，液体无法流出。
与现有技术相比，本实施例具有以下有益效果：
该减震机构1的减震效果相对于现有的橡胶脚垫更好，来自压缩机3的各方向不规则的震动传递到减震机构1的减震脚垫11上后，减震腔110内的液体与减震本体111获得的角动量弱于传统的橡胶脚垫，使其传递震动到底板2上的能力减弱，在密闭的减震腔110内填充的液体减弱了压缩机3的震动，当压缩机3的扭转震动传递到减震本体111上后，内部的液体也影响减震机构1进一步扭转震动，所以对压缩机3的减震效果更好，且由于内部的液体不与外界其他器件接触，所以也不存在漏液的问题。
另外，该减震脚垫11通过设置缓冲部114，形成一圈与底板2的接触面积逐渐增大的横截面，同时在压缩机3与底板2之间过盈配合，过盈配合时端部能有较大的挤压变形余量，在压缩机3进一步向下压迫减震脚垫11时，能挤压变形的余量越来越小，从而装配得越来越紧，这样可以尽量减少缓冲部114以上的区域的变形，使上方的区域保持其设计的状态。
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。
