此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
首先参阅图1，图1是本发明的控制面板组件的装配示意图，图2是本发明的控制面板组件的爆炸图。如图1和图2所示，洗涤设备包括壳体和控制面板组件，其中，控制面板组件包括控制面板1、旋钮组件2和限位组件。控制面板1与上述壳体相连接以共同形成能够容纳洗涤部件的箱体，旋钮组件2以转动方式安装至控制面板1上，限位组件3设置于控制面板1和旋钮组件2之间，以限制旋钮组件2径向和/或轴向移动。具体地，旋钮组件2包括旋钮盖21以及与旋钮盖21相连的主体22。旋钮盖21以转动方式安装至控制面板1的外侧。主体22包括电路板221和设置于电路板221上的编码器222，旋钮盖21与编码器222相连，用户通过扭转旋钮盖21带动编码器222转动以完成调节操作。在此情形下，旋钮组件2和控制面板1之间设置有限位组件3，限位组件3能够限制旋钮组件2——主要是旋钮盖21径向和/或轴向移动，以增加旋钮盖21和控制面板1之间的关联性，从而使得旋钮盖21安装得更加可靠，避免旋钮盖21在被长期扭动后出现偏斜或者易被拔出等现象。也就是说，限位组件3能够通过对旋钮盖21进行限位的方式增加旋钮盖21的安装可靠性，使得旋钮盖21能够承受用户施加的较大转动力矩而不偏离其安装位置，既对旋钮盖21和编码器222的连接具有保护作用，又避免了旋钮盖21与其周围的部件(如控制面板1发生摩擦，保证了旋钮盖21的操作手感。
在一种可能的实施方式中，控制面板1仅包括一层板体，旋钮组件2以和转动方式安装至控制面板1上，限位组件3设置于控制面板1和旋钮组件2之间。
在另一种可能的实施方式中，控制面板1包括主体板11和装饰板12，装饰板12连接至主体板11的外侧，旋钮组件2以转动方式安装至装饰板12上、通过装饰板12固定至主体板11。限位组件3设置于控制面板1和旋钮组件2之间。在此情形下，主体22还包括导光元件223，主体板11上设置有与导光元件223相对应的导光孔和旋钮安装孔。主体22设置于主体板11的内侧，并通过旋钮安装孔与旋钮盖21相连。旋钮盖21设置于装饰板12的外侧，装饰板12上围绕旋钮盖21周围设置有参数符号，导光元件223发出的光能够通过导光孔照亮符号。在旋钮盖21被限位组件3限位的情形下，上述控制面板1的分层设置更有利于限位组件3、旋钮盖21和控制面板1的装配，使得旋钮组件2能够通过分块组装(如装饰板12和旋钮盖21组装后与主体22和主体板11的装配模块组装在一起)的方式快速完成总体安装步骤。下面以上述控制面板1分层设置的方式为例对本发明的技术方案作进一步阐述。
优选地，限位组件3能够限制旋钮盖21的径向和轴向移动。通过限制旋钮盖21的径向转动，使得旋钮盖21能够始终处于编码器222的上方，避免旋钮盖21相对于编码器222的转动部分偏心，且通过径向限制减少了编码器222受到的偏心转矩，延长了旋钮组件2的使用周期。通过限制旋钮盖21的轴向移动，使得旋钮盖21无需装配现有的卡接衬套等轴向卡接构件也能够被轴向限位，在避免了旋钮盖21向内凹进变形或者被意外拔出的同时简化了旋钮组件2的结构。
进一步地，限位组件3限制旋钮组件2径向移动的方式为：限位组件3包括设置于旋钮盖21上的第一抵接构件31和设置于装饰板12上的第二抵接构件32，第一抵接构件31以转动方式抵接至第二抵接构件32，以限制旋钮盖21径向移动。也就是说，在旋钮盖21转动的情形下，旋钮盖21上的第一抵接构件31能够通过抵接至装饰板12上的第二抵接构件32的方式限制旋钮盖21径向移动。
当旋钮盖21受到偏离其转动轴的力矩时，该力矩会通过第一抵接构件31施加在第二抵接构件32上，而不会作用在编码器222上，从而对编码器222起到保护作用。例如，旋钮盖21的中心设置有筒状的转动柱211，转动柱211与编码器222插接配合，以连接旋钮盖 21和电器部分的主体22。在第一抵接构件31和第二抵接构件32抵接配合的情形下，即使旋钮盖21上被施加偏心力矩，该力矩也不会被旋钮盖21传递至编码器222上。此时，旋钮盖21和编码器222之间的连接主要起到力矩传递的作用，旋钮盖21无需通过编码器222进行径向限位，一方面，避免了编码器222的转动部分松动受损，另一方面，使得旋钮盖21的径向限位更加可靠，基本杜绝了旋钮盖21径向偏心错位的可能。
此外，旋钮盖21通过第一抵接构件31直接与装饰板12抵接配合，在装饰板12上设置有参数字符的情形下，无需考虑旋钮盖21与参数符号的对应问题，旋钮盖21在抵接装配至装饰板12的情形下即可与参数符号对准，安装便捷。例如，如图2所示，在装饰板12上设置有卡扣121、主体板11上设置有卡孔的情形下，在旋钮盖21通过第一抵接构件31和第二抵接构件32的抵接配合定位至其安装位置时，旋钮盖21即可与装饰板12上设置的字符对齐，此时，只需将装饰板12通过卡扣121扣合至主体板11上即可，省略了旋钮盖21和参数符号对齐的步骤，安装更加简便。也就是说，第一抵接构件31和第二抵接构件32之间可转动的抵接配合同时具备对旋钮盖21的径向限位作用和定位作用。
继续参阅图1，作为示例，第一抵接构件31为设置于旋钮盖21上的筒状结构，该筒状结构从旋钮盖21的内部向靠近装饰板12的方向延伸形成。第二抵接构件32为设置于装饰板12上的筒状结构，该筒状结构从装饰板12的外侧向靠近旋钮盖21的方向延伸形成。两个筒状结构的轴线均与旋钮盖21的轴线重合，并且两个筒口相对设置的筒状结构的筒径相适应，以使两个筒状结构能够以筒口插合的嵌套方式抵接在一起，从而使得上述两个抵接构件的抵接配合能够沿旋钮盖21的整周转动方向对旋钮盖21进行径向限位。
为了降低上述两个筒状结构的装配难度，进一步地，第一抵接构件31上设置有凸出结构311，第二抵接构件32与凸出结构311彼此抵接。一方面，减少了旋钮盖21和装饰板12之间的接触面积，保证了旋钮盖21转动时的顺畅度。另一方面，降低了第一抵接构件31和第二抵接构件32的装配难度以及加工难度，使得第一抵接构件31 和第二抵接构件32无需整体精加工即可轻松完成抵接装配。作为示例，凸出结构311包括设置于第一抵接构件31两端的环状凸起。当然。凸出结构311还可以设置在第二抵接构件32上，或者，第一抵接构件31和第二抵接构件32均设置有凸出结构311，上述凸出结构311的具体设置位置的改变并不影响两个抵接构件的抵接效果。
关于上述，需要说明的是，首先，第一抵接构件31和第二抵接构件32均不局限于筒状结构，例如，第一抵接构件31和第二抵接构件32中的任意一个还可以包括多个沿旋钮的转动方向布置的条状定位筋。也就是说，第一抵接构件31和第二抵接构件32的设置形状只要满足可转动的抵接配合即可。其次，凸出结构311并不局限于环状结构，例如，凸出结构311还可以包括沿筒状结构的侧壁轴向均匀布置的多个凸点，只要凸出结构311在满足抵接配合的同时不影响旋钮盖21的转动即可。上述结构形式的改变并未超出本发明的原理和保护范围。
另外，限位组件3限制旋钮组件2轴向移动的方式为：除上述(第一/第二)抵接结构外，限位组件3还包括设置于旋钮盖21上的卡接构件33，卡接构件33与装饰板12卡接配合以限制旋钮盖21轴向移动。通过上述设置，使得旋钮盖21沿轴向与装饰板12之间存在卡接配合，避免了旋钮盖21相对于装饰板12向外移动，以对旋钮盖21与编码器222之间连接产生保护效果。
作为示例，卡接构件33为设置于旋钮盖21上的卡勾。如图2所示，该卡勾设置于旋钮盖21的筒状结构的内部。在旋钮盖21的筒状结构嵌套至装饰板12的筒状结构时，卡勾卡接至装饰板12的内侧表面，以限制旋钮盖21沿轴向向外移动。上述设置方式使得装饰板12上无需设置贯通卡接结构(如卡孔)和凸出卡接结构(如卡槽)，使得装饰板12的表面既无可能漏水的结构又设置有凸出的筒状结构，从而使其具有良好的防水效果。并且装饰板12无需设置卡槽结构使得旋钮组件2的结构能够更加紧凑，避免增大旋钮组件2的整体尺寸。
当然，卡接构件33的设置位置和结构形式并不是限定的。例如，卡接构件33还可以是设置于旋钮盖21的筒状结构的端部的环形卡接结构，在组装好的情形下，上述筒状结构的侧壁与装饰板12的 筒状结构抵接配合，上述环形卡接结构卡接至装饰板12的内侧表面。或者，卡接构件33还可以是沿旋钮盖21的边缘设置的卡槽，装饰板12上设置于与该卡槽相匹配的卡接结构，以便卡槽与装饰板12卡接配合限制旋钮盖21轴向移动。
作为一种可替代的实施方式，限位组件3还可以仅限制旋钮组件2的径向移动。例如，限位组件3仅包括限制旋钮盖21径向移动的第一抵接构件31和第二抵接构件32。此时，控制面板组件可以包括其他的轴向限位件。例如，控制面板组件还包括筒状衬套。该筒状衬套的一端与旋钮组件2相连，另一端与主体板11的内侧相连，以限制旋钮盖21轴向移动。
作为另一种可替代的实施方式，限位组件3还可以仅限制旋钮组件2的轴向移动。例如，限位组件3仅包括限制旋钮盖21轴向移动的卡接构件33，此时，旋钮盖21的径向因其与编码器222的连接配合而受到约束。
综上所述，本发明的控制面板组件包括控制面板1、旋钮组件2和限位组件3，其中，限位组件3包括设置于旋钮组件2上的第一抵接构件31和卡接构件3以及设置于控制面板1上的第二抵接构件32。第一抵接构件31和第二抵接构件32抵接配合以限制旋钮组件2的径向移动。卡接构件32与控制面板1卡接配合以限制旋钮组件2的径向移动。通过上述设置，使得旋钮组件2能够通过限位组件3与控制面板1配合，避免旋钮组件2相对于控制面板1上的旋钮安装位置歪斜错位，以防止旋钮组件2转动时与控制面板1之间互相摩擦、影响操作手感，增加了旋钮组件2的安装可靠性。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
