Description

一种液压调平底座及洗衣机 技术领域
本发明涉及洗衣机技术领域，具体地，涉及一种液压调平底座及洗衣机。
背景技术
家用电器，一般在壳体的底部都设置调平装置，在放置家用电器时，通过调节调平装置可使其达到稳定放置状态，调平后放置后，调平装置可支撑家用电器使其保持稳定。
以洗衣机为例，现有洗衣机一般都是在壳体或者整机底部安装有螺栓底脚，螺栓底脚包括螺杆、螺母垫片和橡胶垫，螺母垫片可以在螺杆上下旋动，螺杆也可以在壳体底板的螺孔中上下旋动，通过螺栓底脚的螺杆旋入底板的螺纹孔的长度来实现洗衣机的高度调整，大部分洗衣机的底脚逆时针旋转为调高，顺时针旋转为降低高度，在调整该脚高度后，将防止松动的螺母垫片拧紧以保持稳固。
上述洗衣机的底脚，虽然实现了洗衣机的调平，但需要用户进行手动调节，若洗衣机自重较大或者设置空间狭小，用户操作即为不便。另外，洗衣机在长期的工作过程中的震动也对调平底脚产生作用，易导致其支撑失效，造成洗衣机放置的不平。
例如，现有8KG滚筒洗衣机一般80Kg左右，较为沉重，消费者调节极为不便，即便完成调节也不能保证洗衣机调整为最佳状态，洗衣机在洗涤尤其是由0r/min加速到1400r/min左右进行甩干脱水时，洗衣机一旦不水平或者虚腿问题存在，将导致极大振动，极大的影响了消费者的使用舒适性。
另外，洗衣机不平导致的震动可能会使底脚螺丝松动，使底脚托架垂直移动，这种不稳定性可能会改变洗衣机的水平状态，导致产生更强烈的震动。这种恶性循环使得洗衣机用的时间长了，噪音会变得越来越大，对洗衣机本身也造成一定的损伤，缩短了使用寿命。
因此，现有洗衣机的调平存在需要手工调节，费时费力且精度较差的问题。
有鉴于此，特提出本发明。

具体实施方式
下面结合附图对本发明的一种液压调平底座及洗衣机进行详细描述：
实施例一
如图5、图6、图7及图8所示，本实施例的一种液压调平底座，包括可进行组合连接或者独立使用的支架2101和设置在支架2101下部的调平底脚10，支架2101上部为用于承载的支撑面；所述的调平底脚10内部填充液压介质，液压介质可在调平底脚10内部和/或在调平底脚10之间流通实现自动调平。
本实施例的液压调平底座的支架2101下部设置有调平底脚10，液压介质可在调平底脚10内部和/或在调平底脚之间流通，这样，承受大压力下的调平底脚10压缩量大，承受小压力的调平底脚10在液压的作用下还能伸长，进而自动实现高度的调平。
本实施例液压调平底座的调平底脚10利用液压原理，能够根据实际的使用环境进行及时有效的调节，调整效果更好，适用性强。
本发明的液压调平底座可被应用到一些对放置稳定性要求较高的场合或者设备上，实现更好的调平效果。
本实施例的支架2101可单独使用，将其分别放置在需要进行支撑调平的设备下部即可，也可以进行组合连接使用，将其连接成为一体后再整体放置在需要进行支撑调平的设备下部，可根据具体的使用要求进行选择，使用灵活，应用范围广。
为了便于将所述的支架2101进行组合使用，本实施例的液压调平底座还包括连接两个支架2101的连接横梁2105；所述支架2101的内部具有中空结构2110，支架2101的端部开设与中空结构2110连通的插入口2106，所述连接横梁2105的两端分别插入两个支架2101的插入口2106并固定在中空结构2110内，将两个支架2101连接为一体结构。
本实施例通过连接横梁2105将两个支架2101连接为一体，不仅简单方便，而且确保了液压调平底座的稳定性。另外，本实施例的支架2101之间采用连接横梁2105进行组合连接的方式可拓展支架2101的连接个数，根据实际的使用将相应个数的支架2101进行组合连接构成一体的液压调平底座。
作为本实施例的一种优选实施方式，所述的支架2101包括四个，支架2101包括相互垂直设置的两条边，两条边的内部具有中空结构2110，两条边的端部分别开设插入口2106；所述的连接横梁2105包括四个，依次插入四个支架2101的插入口2106并固定其中，将四个支架2101连接为方形的一体框架。
本实施例的支架2101组合连接构成方形框架的液压调平底座，可更好的适用于洗衣机、干衣机等家电设备。
进一步地，本实施例支架2101的相互垂直设置的两条边上分别沿中空结构2110的设置方向设置第一连接固定孔2107，所述连接横梁2105上设置第二连接固定孔2109，所述的第一连接固定孔2107包括一个/至少两个，第二连接固定孔2109对应包括至少两个/一个；通过调节第二连接固定孔2109与第一连接固定孔2107相对应，连接件穿过第二连接固定孔2109和第一连接固定孔2107进行固定连接，以调节连接横梁2105插入支架2101内中空结构2110的长度。
本实施例的一个第一连接固定孔2107对应多个第二连接固定孔2109，通过调节横梁2105使得不同的第二连接固定孔2109对准第一连接固定孔；或者，多个第一连接固定孔2107对应一个第二连接固定孔2109，通过调节横梁2105使得第二连接固定孔2109对准不同的第一连接固定孔2107；再用连接件穿过第二连接固定孔2109和第一连接固定孔2107进行固定连接，实现对连接横梁2105的连接长度的调节，进一步调节两个支架2101之间的长度L，以适应多规格洗衣机。
进一步地，本实施例的支架2101的外边缘高于支撑面设置，即支架2101的外边缘形成凸起边缘2102，凸起边缘2102在放置洗衣机等设备时可对底部进行限位，确保放置的稳定性。
本实施例支架2101的支撑面上设置多个同心的波纹状加强筋2104和与其垂直设置的 径向加强筋2103，一方面可确保支架2101的支撑面强度，另一方面可增加洗衣机等设备与液压调平底座之间接触的摩擦力，确保放置的稳定性。
本实施例所述的波纹状加强筋2104优选为采用二次注塑在支撑面上的弹性体，优选为丁腈橡胶，增大洗衣机的螺栓底脚19和支架2101的支撑面间摩擦阻力，防止移位。为增强所述波纹状加强筋2104强度，一体注塑了径向加强筋2103。
另外，本实施例支架2101的背部设置有加强筋2108，以进一步增强支架2101的强度。
作为本实施例的一种优选实施方式，所述的调平底脚10包括固定部和活动部，固定部和活动部之间形成中空腔室，中空腔室内填充液压介质；所述相邻的两个调平底脚之间分别通过高压油管组连通中空腔室，或者所有所述的调平底脚通过高压油管组分别连接至连通装置实现所有调平底脚的中空腔室相互连通；在压力作用下，所述的液压介质可在相互连通的底脚的中空腔室之间流通，活动部随液压介质流通伸缩进行自动调平。
本实施例液压调平底座的调平底脚10之间进行连通，调平底脚10内的液压介质可在调平底脚10之间进行流通，调节效果更好，调节范围更大。
作为本实施例的一种优选实施方式，所述相邻的两个调平底脚10之间分别通过高压油管组13连通中空腔室相互连通；所述连接横梁2105的内部具有用于高压油管13组通过的中空通道。这样，连接横梁2105对高压油管13具有一定的保护作用，而且整体更加简洁美观。
由于本实施例的连接横梁2105的连接长度可以进行调节，与之相应的，设置在连接横梁2105内部的高压油管13也应该可调节或者具有多种可选择的长度规格。
具体地，高压油管13为可伸缩管结构，以实现长度的调节。或者，高压油管13为弹性管，具有较高的弹性形变量以适应连接横梁2105的长度调节。或者，高压油管13设计为多种长度规格，在实际的使用中，根据连接横梁2105的连接长度进行选择应用。
作为本实施例的一种优选实施方式，所有所述的调平底脚10通过高压油管组13分别连接至连通装置15实现所有调平底脚的中空腔室相互连通；所述液压调平底座还包括对角连接梁，对角连接梁的两端分别连接对角设置的两个支架2101；所述对角连接梁的内部具有用于放置高压油管组和连通装置的中空通道。
由于高压油管组13是交叉设置，对角连接梁也是对角设置，为了将高压油管组13设置在对角连接梁内的中空通道内，所述的对角连接梁包括两个十字状凹槽结构，将高压油管组13对应放置在其中一个十字状凹槽结构的凹槽内，再将另一个十字状凹槽结构对应扣合在上述十字状凹槽结构的凹槽开口上，以实现将高压油管组13设置在对角连接梁内的中 空通道内，不仅对高压油管组13具有一定的保护作用，而且整体更加简洁美观。
实施例二
如图1-图4所示，本实施例的一种洗衣机，具有实施例所述的液压调平底座21，包括壳体9和设置在壳体9内用于洗衣的筒体组件，所述壳体9底部的四个角分别放置在所述液压调平底座21的四个支架2101上。
本实施例的洗衣机放置在液压调平底座21上，实现自动调平，且所述液压调平底座在洗衣机的洗涤、脱水过程中还能对偏载自调平，因而实现更低振动和更小的噪音。
具体地，本实施例的壳体9包括底板901，底板901的四个角上安装有螺栓底脚19，所述的螺栓底脚19分别放置在所述液压调平底座21的四个支架2101上。这样，可不改变现有洗衣机的结构，用户可根据选择是否配备液压调平底座21，可选择性强。
另外，本实施例可取消洗衣机原有的螺栓底脚19，将壳体9的底板901的四个角直接放置在液压调平底座21上，在不改变洗衣机的结构情况下，直接组合，实现更好的自动调平效果。
本发明以滚筒洗衣机为例举例说明，滚筒洗衣机包括：
壳体9：包括上板902、前板903、侧板904和底板901，保持整个洗衣机的框架及外观；
洗涤盒20，用于放置洗衣粉、洗涤液或者柔顺剂等；
控制面板14，用于操作洗衣机；
门体17，用于打开取出或者放入衣物。
底板901，安装有调平底脚，实现洗衣机的自动高度调节；
盖板18，设置在前板903的下部。
本实施例以滚筒洗衣机为例，阐述了本发明实现滚筒洗衣机自动调平的原理和方法，可以很容易联想到的是本发明的液压调平底座可以应用到波轮洗衣机。
本实施例以洗衣机为例，阐述了本发明实现洗衣机自动调平的原理和方法，可以很容易联想到的是本发明的液压调平底座可以应用到冰箱、冰柜、洗碗机等家用电器上。
实施例三
如图9-图19所示，本实施例的调平底脚10包括底脚座、柔性容纳体6和调整脚4；所述的底脚座内具有中空腔室，底脚座上分别设置与中空腔室连通的节流孔7和阀孔8，节流孔7和阀孔8分别连接高压油管；所述的柔性容纳体6设置在中空腔室内，柔性容纳体6内部具有容纳腔室，容纳腔室内部填充液压介质，在压力作用下多个底脚内的液压介质可通过高压油管相互流通；所述调整脚4的一端可相对滑动的设置在中空腔室内，柔性容纳 体6与调整脚4相接触或者连接。
本实施例的调平底脚10根据液压原理，在底脚中填充液压介质，底脚对于不同的压力，由于液压介质的流动性使得底脚自动进行适应性的调整。
由于本实施例调平底脚10的节流孔7和阀孔8分别连接高压油管，通过高压油管可实现底脚之间的连通，调整范围更大，调整效果更好。
由于本实施例的调平底脚10将液压介质盛放在密封的柔性容纳体6内，且该柔性容纳体6被安置于调整脚4内部，有效解决液压介质泄露的问题，确保底脚工作的稳定性。
因此，本实施例的调平底脚10结构简单，成本较；使用方便，可靠性高；可显著降低振动，降低噪音，提高洗衣机的用户体验的舒适度。
进一步地，本实施例的底脚座包括相互连接的座体1和护套3，座体上设置凹槽，座体1和护套3之间设置压环11；所述的柔性容纳体6一端具有开口604，开口处具有密封结构603，密封结构603的一端设置在凹槽内，另一端在压环11的压合下保持柔性容纳体6与座体1之间的密封连接。
进一步地，本实施例的座体1内设置一个节流孔7和至少两个阀孔8，节流孔7和阀孔8分别与柔性容纳体6的开口604连通，节流孔7设置在阀孔8中间；在第一压力下，所述的节流孔7和阀孔8均保持导通，在第二压力下，柔性容纳体6压缩至堵塞住阀孔9，节流孔7保持导通。
本实施例的座体1上设置多个油嘴2，油嘴2分别与节流孔7和阀孔8相连通，油嘴2具有防脱凸台201，防脱凸台201的外径大于高压油管的内径，具体为0.1mm-1.5mm。
油嘴2的起始端设置引导结构202，具体地导引结构202为倒角结构，使得油嘴起始端容易插入油管。
具体地，如图所示，本实施例的调平底脚包括一个节流孔7和两个阀孔8，节流孔7设置在两个阀孔8之间，所述的节流孔7连接第二油嘴204，两个阀孔8分别连接第一油嘴203和第二油嘴205。
座体1上具有多个安装孔101，可以通过螺栓或者螺钉紧固在洗衣机的底板901上，由此可以联想到的是座体1中心位置具有一个螺纹柱，旋入洗衣机的底板901上。
本实施例的调平底脚，所述的柔性容纳体6的开口604与中空腔室之间具有细径结构602，细径结构602的内径均小于开口604和中空腔室的内径。
本实施例柔性容纳体6的细径结构602，中间有与开口604保持导通的油孔，细径结构602的特点就是油孔的有可以一直流入或者流出节流孔7、阀孔8的液压介质；一旦调整脚 4的压力太大细径结构602的周边橡胶会贴合在座体1上，密封阀孔8，实现更大的节流作用。
本实施例的柔性容纳体6具有波纹管段，波纹管段内部为中空腔室，波纹管段使得柔性容纳体6在压缩或者伸长时产生不必要的压褶，提高使用寿命。
本实施例的调平底脚10，所述的护套3内壁上设置竖向限位凹槽301，调整脚4的外壁上相应的设置有竖向限位凸起401，竖向限位凸起301与竖向限位凹槽401配合以限定调整脚竖直上下伸缩运动。这样设置具有以下优点：
(1)使得调整脚4竖直上下运动，不发生侧偏。
(2)防止调整脚4在护套3中的旋转运动，大大降低了洗衣机的振动。
(3)有效防止了调整脚4从护套3中脱落下来，避免柔性容纳体6爆裂，或者直接接触地面因锐物而造成爆裂。
如图17所示，本实施例的调平底脚包括第一底脚和第二底脚，第一底脚和第二底脚分别具有节流孔7和阀孔8，节流孔7和阀孔8分别与中空腔室连通；所述第一底脚的节流孔7与第二底脚的阀孔8通过高压油管连接，第一底脚的阀孔8与第二底脚的节流孔7连通过高压油管接。
具体地，本实施例的第一底脚和第二底脚分别具有一个节流孔7和第一阀孔、第二阀孔两个阀孔5，节流孔7、第一阀孔和第二阀孔分别与中空腔室连通；所述第一底脚的节流孔7与第二底脚的第一阀孔通过第二高压油管1302连接，第一底脚的第一阀孔与第二底脚的节流孔7连通过第一高压油管1301连接，第一底脚的第二阀孔与第二底脚的第二阀孔通过第三高压油管1303连接。所述的第一高压油管1301、第二高压油管1302和第三高压油管1303组成液压管组13。
如图18所示，在液压调平底座21的四个支架2101上设置相互连通的至少四个底脚10；每个底脚10内填充液压介质和气体，在第一压力范围内，每个底脚10内的液压介质与气体之间相互作用实现活动部伸缩，进行自动调平，在第二压力范围内，相互连通的底脚10内的液压介质与气体之间相互作用实现活动部伸缩，进行自动调平。这种方式，实现了所有底脚之间的连通，液体介质可在所有底脚之间进行流通，调整范围更大，调整效果更好。
具体地，所述的底脚10内部具有用于填充液压介质和气体的封闭腔室，所述的封闭腔室上连通高压油管组13，每个所述底脚10的高压油管组13分别连通至连通装置15以实现所有底脚10之间的相互连通。
本实施例的调平底脚以气体作为弹性介质，液体作为传力介质，不但具有良好的缓冲能力，还具有减振作用，同时还可根据承受压力的大小调节底脚自身的高度。
如图19所示，具体讲解调平原理，当洗衣机安装后，由于地面16不平，导致不同的底脚的水平高度不同，位于地面凹坑1601处的底脚位置低。由此可以知道的是，位置高处的底脚首先承受洗衣机的重量，并且承受的重力大，位置低的底脚由于虚腿或者承受的重力小。位置高处的底脚的调整脚在大的压力下将上移，整个底脚的高度变小使充满液压油的柔性容纳体6的中空腔室的容积压缩减小，迫使液压介质进入节流孔或者阀孔通过高压油管组进入位置低处底脚内，使位置低处底脚的柔性容纳体6的液压介质越来越多，使得柔性容纳体6膨胀推动调整脚伸长。
当位置高处底脚和位置低处底脚的液压相同，液压介质不再由高压油管组流动，调整脚与洗衣机底板的相对位置不再变化，完成调平底脚的自动调整。
在洗衣机洗涤或者甩干的过程中，由于液压介质还可以缓慢流动自调平，洗衣机的振动噪音大大降低。
需要对上述实施例进一步说明的是：
本发明实施例中的底脚两两联通，也可以是三个乃至更多，数量N≥2，优选两个，成本最低，且能够实现较好的效果。
本发明实施例中使用连通装置15的四个端口分别连接四个底脚，可以推理到的是使用一个具有三、五、六，N个端口的连通装置15，其所述端口分别连接三、五、六，N个底脚。上述实施例仅仅是能够实现所述功能情况下用最适合的4个，以实现成本的控制到最小。以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
