Description

轴承支撑座及滚筒洗衣机
本申请要求申请日为2017年11月13日、申请号为201711116165.5、名称为“一种轴承支撑座及滚筒洗衣机”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及洗衣机技术领域，例如涉及一种轴承支撑座及滚筒洗衣机。
背景技术
滚筒洗衣机的内筒轴由前、后两个轴承支撑旋转，两个轴承压装在金属的轴承支撑座中，前轴承的前端安装有油封，防止筒内的洗涤水等液体进入到轴承支撑座的轴承室中，引起轴承生锈。
相关技术中，轴承和筒内的洗涤水等液体之间虽然有油封进行密封，但由于油封安装时可能会造成油封偏斜导致密封效果降低，会有少量水渗入到轴承室中与轴承接触，引起轴承生锈；此外，由于滚筒洗衣机加热洗涤时，会有水蒸气产生，水蒸气也可能穿过油封，进入到轴承室中，并与轴承室中的轴承接触，引起轴承生锈。
发明内容
本公开提供了一种轴承支撑座及滚筒洗衣机，能够解决相关技术中由于油封安装精度不高，而导致少量水或水蒸汽进入轴承室内而引起轴承生锈的技术问题。
一实施例提供了一种轴承支撑座，包括轴承室，所述轴承支撑座开设有透孔，所述透孔设置为将所述轴承室中的液体或水蒸汽在接触轴承前排出所述轴承室。
一实施例还提供了一种滚筒洗衣机，包括洗衣机外筒及上述的轴承支撑座，所述轴承支撑座安装于所述洗衣机外筒上。

具体实施方式
本实施例提供了一种轴承支撑座10，如图1-图4所示，该轴承支撑座10安装于滚筒洗衣机外筒20上，该轴承支撑座10开设有多个透孔1，透孔1能够将轴承室30中的液体或水蒸汽在接触轴承前排出轴承室30。其中，透孔1包括透气孔11和透水孔12，所述透气孔11位于所述透水孔12上方。
本实施例通过在轴承支撑座10上设置透气孔11，使得进入轴承室30内的水蒸汽在未接触轴承之前就通过透气孔11排出轴承室30外，避免了水蒸汽对轴承的腐蚀作用；在滚筒洗衣机洗涤的过程中，有少量水渗入到轴承室30中，本实施例通过在轴承支撑座10上设置透水孔12，将进入轴承室30内的水未接触轴承之前就通过透水孔12排出，避免了进入轴承室30内的水对轴承的腐蚀作用，保证了轴承的使用寿命。此外，本实施例提供的轴承支撑座10结构简单，加工方便，降低了生产成本。
如图2和图3所示，上述轴承支撑座10上设置有与所述透气孔11和所述透水孔12连通的环形空腔3，环形空腔3与轴承支撑座10的外部连通，在轴承支撑座10上设置与透气孔11和透水孔12连通的环形空腔3，使得由透气孔11排出的水蒸汽以及由透水孔12排出的水可以通过环形空腔3及时地排至外部，避免了水蒸汽和水在轴承支撑座10内贮存而导致轴承支撑座10上的部件及周围部件腐蚀。
如图1所示，上述轴承支撑座10包括同轴设置的内圈5和外圈6，所述环形空腔3由所述内圈5和所述外圈6之间的间隙形成，所述透气孔11和所述透水孔12均贯穿设置于所述内圈5上，如图3所示，内圈5安装有前轴承51、后轴承52及油封53，所述油封53设置于所述前轴承51远离所述后轴承52的一端，且所述前轴承51与所述油封53之间设置有缝隙，所述透气孔11和所述透水孔12连通于所述缝隙。水蒸汽和水经过油封53进入前轴承51和油封53之间的缝隙，并通过透气孔 11和透水孔12进入环形空腔3内，然后排出，保证了水蒸汽和水在未接触前轴承51之前就通过透气孔11和透水孔12排出，有效地防止了轴承生锈，保证了轴承的使用寿命。在一实施例中，前轴承51位于轴承支撑座10靠近洗衣机内筒(未示出)的一端。
上述透气孔11设置于透水孔12的上方，在一实施例中，透气孔11位于内圈5的顶部，透水孔12位于内圈5的底部，其中，本实施例中，内圈5上设置有多个透气孔11和多个透水孔12，以方便及时将水蒸汽和水排出，本实施例对透气孔11和透水孔12的数量不作限定。在一实施例中，内圈5的最高点设置有透气孔11，以及最低点处均设置有透水孔12，由于水蒸汽为气态，容易流动至高处，将内圈5的最高点处设置透气孔11，方便了水蒸汽的排出，此外，水蒸汽也可以通过透水孔12排出；进入轴承室30内的水由于自身的重力作用，最终容易滑至内圈5的最低点，并从设置于内圈5最低点处的透水孔12排出，此外，当水蒸汽冷却为液态后，也可以从透水孔12排出。将最低点处均设置有透水孔12以及最高点设置有透气孔11，充分保证了轴承支撑座10方便将轴承室30内的水蒸汽和水排出。
上述环形空腔3内设置有板筋4，其中，板筋4周向均布于所述环形空腔3内且所述板筋4的两个相对侧分别连接于所述内圈5和所述外圈6。通过在环形空腔3内设置板筋4，增加了轴承支撑座10的强度，此外，通过设置板筋4，将环形空腔3分割为多个小腔室，透气孔11和透水孔12通过与小腔室连通，使水蒸汽和水排至小腔室内，小腔室对水蒸汽和水具有导流的作用，方便轴承支撑座10将水蒸汽和水排至轴承支撑座10外部。
本实施例中的轴承支撑座10为锥形结构，如图4所示，所述外圈6的内径自外圈6靠近所述油封53的第一端向外圈6远离所述油封53的第二端逐渐增大，所述外圈6的外径自外圈6靠近所述油封53的一端向外圈6远离所述油封53的第二端逐渐减小。所述内圈5的外径自内圈5靠近油封53的第一端向内圈5远离所述油封53的第二端逐渐减小，使内圈5呈锥形结构，方便水蒸汽和水从透气孔11和透水孔12排出后，顺着内圈的外壁排出轴承支撑座10外。
本实施例还提供了一种滚筒洗衣机，该滚筒洗衣机安装有上述轴承支撑座10。通过安装上述轴承支撑座10，使得进入轴承座内的水蒸汽和水在接触轴承前排出轴承室30外，有效地防止了轴承生锈，进而保证了轴承的寿命。
