Description

旋钮及设有该旋钮的洗衣机 技术领域
本公开涉及洗衣机及其零部件技术领域，例如涉及一种旋钮及设有该旋钮的洗衣机。
背景技术
滚筒洗衣机是借助滚筒上的提升筋将衣物升至一定高度，及衣物与滚筒间的摩擦对衣物进行洗涤的，类似于手工摔打搓洗的原理，滚筒洗衣机对衣物的磨损小且衣物间不缠绕，因此深受广大用户的喜爱。随着衣物种类的增加、衣物质量的提高以及人们对衣物呵护要求的提高，滚筒洗衣机的技术得到了极大地提升，人们对程序选择的体验要求也随之提高，其中，旋钮上程序的指示是程序选择体验中重要的一项。相关技术中，滚筒洗衣机的程序指示通过旋钮上的图标或指示灯来实现。由于指示灯需要借助导光柱或匀光膜等实现透光且需要在印制电路板(Printed Circuit Board，PCB)(电路控制板)上增加发光二极管(Light Emitting Diode，LED)等，不仅增大了产品成本，而且增加了能耗，因此，生产商越来越青睐于在旋钮上增加小的指示结构来实现程序选择指示，然而，由于指示结构小，定位和安装成为了旋钮设计的重点和难点。
相关技术中的旋钮有两种。如图1和图2所示，第一种旋钮包括旋钮体11’和编码器安装体12’两部分，编码器安装体12’外周边缘处设置有旋钮指示结构13’。借助编码器安装体12’上的卡扣和旋钮体11’上的弹片将编码器安装体12’和旋钮体11’安装至一起，且编码器安装体12’上的旋钮指示结构13’也安装至旋钮体11’上。该方式安装简单，但由于编码器安装体12’与旋钮体11’的配合、旋钮指示结构13’与旋钮体11’的配合以及编码器安装体12’与编码器(图中未示出)的配合效果均与编码器安装体12’的结构紧密相关，因此，对编码器安装体12’的安装精度要求高，增加了模具制造成本。难保证编码器安装体12’与旋钮体11’的之间的配合、旋钮指示结构13’与旋钮体11’之间的配合以及编码器安装体12’与编码器(图中未示出)之间的配合均配合到位，可能造成旋钮的安装不良。编码器安装体12’与编码器一旦出现不配合的现象可能造成产品性能故障。如图3和图4所示，第二种旋钮包括旋钮体21’、旋钮 盖22’和旋钮指示片23’三部分，旋钮体21’上开有安装孔24’，安装过程中，将旋钮指示片23’插进旋钮体21’中，通过粘结或熔敷等工艺将旋钮指示片23’固定至旋钮体21’中，将旋钮盖22’粘结或借助卡扣固定至旋钮体21’中，该方式组装工艺复杂、成本高，且易出现粘结不良现象。
综上所述，亟需一种滚筒洗衣机旋钮，以解决上述相关技术中存在的制造成本高、组装工艺复杂、产品不良率高等问题。

具体实施方式
下面结合附图并通过具体实施方式来说明以下实施例的技术方案。
可选实施例一
本可选实施例提供一种旋钮。如图5和图6所示，该旋钮包括旋钮指示片32和具有插接口314的旋钮体31，相比于相关技术中的包括三种零部件的旋钮，本实施例中的旋钮具有更少的零部件、结构简单，成本低。
本实施例中，旋钮体31为中空的柱状结构，旋钮体31具有顶面的一端可以为顶部，开口的一端可以为底部，旋钮体31的顶部中心处向中空的腔体方向形成有卡接柱318。借助于卡接柱318，旋钮和PCB(图中未示出)上的编码器可以组装在一起，由于PCB是通过卡扣或螺钉等方式固定于洗衣机本体上，因此，旋钮与编码器组装，即，旋钮安装到了洗衣机本体上。使用旋钮时，通过旋钮指示片32与编码器的配合，用户选择洗衣程序，例如，如果用户想选择“棉麻”功能，可以将旋钮指示片32旋转至“棉麻”字样处，PCB上的控制器可以获取编码器的位置信息，并依据编码器的位置信息运行“棉麻”程序。
相比于指示灯的指示方式，上述指示方式能节约成本、降低功耗，因此在洗衣机的功能指示上得到广泛应用，但上述指示方式中，旋钮中的指示结构小，给结构设计造成了一定的困难，本实施例中设计了旋钮体31和旋钮指示片32的结构，解决了上述难题。
图7中，在与插接口314相对的位置处，旋钮体31的内侧面向内凹陷形成方形槽316，方形槽316的底部具有开口，弹片311位于开口中，该弹片311具有弹性，能沿旋钮体31的径向向卡接柱318的方向弹起。如图7中所示，弹片311的下表面则为底面317。
在与插接口314相对的位置处，旋钮体31的内侧面形成有第一配合部315， 该第一配合部315至少包括第一轴向配合面312和第一周向配合面313。如图8所示，方形槽316靠近旋钮体31底部的一端的侧面作为第一轴向配合面312，第一轴向配合面312与旋钮体31的中心沿卡接柱318方向的轴线垂直，旋钮体31的内侧面向内延伸还形成有第一周向配合面313，第一周向配合面313包括位于插接口314两侧的两个周向侧面。
图9中，旋钮指示片32的主体为竖直的片状结构，在与弹片311相应的位置处，旋钮指示片32向外凸出形成有截面为梯形状的卡扣321。如图9中所示，卡扣321的上表面则为顶面325。
旋钮指示片32的一端向外延伸形成一个块状结构，即，第二配合部324，该块状结构的底面作为第二轴向配合面322，以旋钮指示片32的主体为中心的两侧的两个侧面作为第二周向配合面323。
安装旋钮时，如图10所示，旋钮指示片32通过插接口314插入至旋钮体31内，将旋钮指示片32自旋钮体31的底部推向旋钮体31的顶部，借助旋钮体31的弹片311弹性和旋钮指示片32的卡扣321结构，将旋钮体31和旋钮指示片32卡接至一起。
安装旋钮完成后，弹片311的底面317与卡扣321的顶面325相抵接，用于限制旋钮指示片32向旋钮体31的底部的滑动；第一轴向配合面312与第二轴向配合面322相抵接，用于限制旋钮指示片32向旋钮体31的顶部的滑动；第一周向配合面313和第二周向配合面323相抵接，用于限制旋钮指示片32相对旋钮体31的径向滑动。通过卡扣321和弹片321的配合、第一轴向配合面312与第二轴向配合面322的配合、第一周向配合面313和第二周向配合面323的配合，可将旋钮指示片32固定在旋钮体31上，组装工艺简单、产品不良率低、安装精度高、结构简单，省去了粘结、熔敷等繁琐的组装工艺。
本实施例中的旋钮相比于相关技术中结构复杂的旋钮，降低了材料成本。
可选实施例二
