具体实施方式
滚筒洗衣机在机身前部的门体上设置有观察窗，方便用户查看机筒内衣物的洗涤情况。观察窗包括从外到内依次设置的窗屏、外框、中框、玻璃盆和内框，其中，玻璃盆固定在中框与内框之间，内框上设有定位玻璃盆的环形定位筋。环形定位筋可以与玻璃盆同心设置，且玻璃盆的边缘与环形定位筋之间可以采用间隙配合方式进行固定。
在洗衣机的使用过程中，玻璃盆可能在内框的径向上产生移位，导致玻璃盆的中心与窗垫的中心不同心，降低玻璃盆装配的稳定性，造成玻璃盆与窗垫密封不良，以及滚筒洗衣机工作时漏水。
环形定位筋的结构强度低，固定不牢靠，不能对玻璃盆起到很好的支撑作用，容易使玻璃盆沿轴向产生晃动，影响洗衣机的正常运行。
本实施例提出一种定位结构，该定位结构包括用于安装待定位件的底板，其中，底板上固定设置有至少两组具有弹性的缓冲筋，缓冲筋的底部与底板的宽度的方向的夹角不为直角，以及缓冲筋上设有向底面倾斜的斜面。当将待定位件安装至底板时，所述待定位件的边缘抵住斜面，缓冲筋在待定位件的挤压下向一侧发生弹性变形，使待定位件沿斜面下滑至底板。底板的宽度是底板的两边缘之间距离最短的连线。
本实施例中的缓冲筋在自身弹力的作用下抵住待定位件，能够提高待定位件的安装对中性，防止待定位件在运行过程中发生移位，使得待定位件在底板上的不产生位移。该缓冲筋结构简单、安装使用方便，无需增加零件的加工精度，缩短了加工和装配时间，有利于产品的大批量生产。
本实施例中的定位结构可适用于定位具有环形边缘的零件，如盆状零件、 盘状零件或环形零件。
实施例一
如图1-图5所示，本实施例提供了一种定位结构，该定位结构可用于定位滚筒洗衣机的玻璃盆。该滚筒洗衣机的前部设有门组件，门组件包括内框2和安装在内框2上的玻璃盆1。内框2上设有定位结构，玻璃盆1由该定位结构进行定位。当门组件与滚筒洗衣机的主体闭合时，玻璃盆1与洗衣机的窗垫密封抵接，防止洗衣机门组件发生漏水。
该定位结构包括设于内框2上的底板23，底板23上设有环形的定位筋21，定位筋21的内侧设有与定位筋21同心的支撑筋22。定位筋21设置在远离底板23中心的底板边缘，支撑筋22设置在靠近底板23中心的底板边缘。
定位筋21与底板23之间的高度大于支撑筋22与底板23之间的高度，缓冲筋24固定设置在定位筋21与支撑筋22之间。
缓冲筋24包括成台阶状的缓冲部241和支撑部242，即，缓冲部241远离底板23的顶端与底板23之间的距离不等于支撑部242远离底板23的顶端与底板23之间的距离，缓冲部241与定位筋21相连。
缓冲部241与底板23之间的高度可以与定位筋21与底板23之间的高度相同，缓冲部241与玻璃盆1的外边缘过盈配合。支撑部242与支撑筋22相连，支撑部242与底板23之间的高度可以与支撑筋22与底板23之间的高度相同，支撑部242和支撑筋22一起支撑玻璃盆1外边缘的底部。
为便于玻璃盆1顺利安装至底板23，缓冲部241与支撑部242之间设有斜面243，该斜面243由缓冲部241向支撑部242方向倾斜设置，以便于支撑玻璃盆1的外边缘。
倾斜设置的缓冲筋24受到玻璃盆1挤压时，能够向一侧发生弹性变形，从而使玻璃盆1在重力作用下沿斜面243下滑至支撑部242。缓冲筋24在自身弹力的作用下，抵接在玻璃盆1的边缘，防止玻璃盆1发生移位。
可选的，该缓冲筋24的支撑部242设置为从支撑玻璃盆1的边缘，强化内框2的支撑强度，并从轴向限制了玻璃盆1的位移。该缓冲筋24的缓冲部241可以抵住玻璃盆1的外边缘，通过过盈配合的方式限制玻璃盆1沿径向的移动。
可选地，如图1和图2所示，本实施例的底板23的圆周方向布置有六组缓 冲筋24，多个相邻两个缓冲筋24之间的弧长均相同，以确保玻璃盆1受力均衡，从而在关闭门组件后，门组件与窗垫具有良好的同心度，防止洗衣机发生漏水。
可选地，上述每组缓冲筋24均包括一个独立缓冲条，且该独立缓冲条与定位筋21切线之间的夹角为锐角。由于缓冲筋24相对于定位筋21为倾斜设置，因而当缓冲筋24受到玻璃盆1的挤压时，具有一定的变形空间，能够在自身弹性力的作用下，抵住玻璃盆1的边缘。
该缓冲筋24在限制玻璃盆1移动，该缓冲筋24也能够缓冲一定的外力冲击。在装配过程中，由于缓冲筋24受到挤压有一定的回弹力，玻璃盆1在回弹力的作用下能够自动修正到合适位置，保证装配的准确性。
上述实施例中的缓冲筋24的横截面可以为矩形、梯形、半圆形或三角形，可选地，本实施例缓冲筋24的横截面为矩形，具有矩形横截面的缓冲筋24的制作过程简单，强度好，弹性佳，能实现缓冲的功能。上述实施例中缓冲筋24的缓冲部241和支撑部242的厚度可以相同，厚度可在1-10mm之间取值。
上述实施例中的缓冲筋24可以由具有弹性的热塑性塑料或橡胶制成，例如缓冲筋24可以由聚丙烯与碳酸钙混合物制成，其中碳酸钙所占质量分数为20％-30％。该聚丙烯与碳酸钙混合物形成的缓冲筋24的强度高，弹性适中，生产成本低，而且注塑后制品缩水量小，成品率高。
可选地，上述实施例中内框2由聚丙烯与碳酸钙混合物制成，并通过注塑工艺一体制作成型，即缓冲筋24与定位筋21、支撑筋22和底板23为一体式结构，该结构简化了制作工艺、节省了生产成本，增加了缓冲筋24和内框2的强度。
综上，上述实施例中的定位结构能够实现滚筒洗衣机玻璃盆1在内框2上的准确定位，防止在洗涤过程中玻璃盆1发生移位和晃动，避免了窗垫与玻璃盆1的不同心导致密封不好和漏水的问题。
实施例二
本实施例提出一种用于滚筒洗衣机的定位结构，在实施例一中的定位结构的基础上，本实施例中的定位结构与实施例中的定位结构的区别在于：缓冲筋24的设置。
如图6和图7所示，底板23的圆周方向布置有六组缓冲筋24，多个相邻两 个缓冲筋24之间的弧长均相同。其中每组缓冲筋24均包括两个相对于沿底板23的宽度方向对称、呈第一角度设置的组合缓冲条。所述第一角度大于0度。每个组合缓冲条可以与实施例一中的独立缓冲条结构相同，每个组合缓冲条与定位筋21切线之间的夹角为锐角。组合缓冲条的设置增加了缓冲筋24的承压能力和抗变形能力，能够保证玻璃盆1的定位准确性和使用稳定性。
可选的，每组缓冲筋24的两个组合缓冲条在靠近定位筋21的一端相互连接，在靠近支撑筋22的一端两个组合缓冲条不相交，且两个组合缓冲条之间的夹角大于或等于90度，以确保为玻璃盆1提供足够的支撑力和，以及抵抵住玻璃盆1。
上述缓冲筋24的组数也可设为奇数组或不等于6的偶数组，缓冲筋24沿定位筋21的圆周方向布置。可以采用独立缓冲条与组合缓冲条间隔设置的方式，增加玻璃盆1的定位准确度。每组缓冲筋24也可以包含三个或更多个组合缓冲条。
工业实用性
定位结构及具有该定位结构的滚筒洗衣机中，定位结构的结构简单，安装方便，通过待定位件边缘与缓冲筋的过盈配合，提高了待定位件的安装对中性，使得待定位件在底板上的位置不发生变化，提升了洗衣机门组件的密封性，避免了窗垫与玻璃盆不同心引起的漏水。
