旋钮组件和电器设备
本申请要求于2020年12月29日提交到中国国家知识产权局、申请号为“202011595610.2”、发明名称为“旋钮组件和电器设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电器设备技术领域,具体而言,涉及一种旋钮组件和电器设备。
背景技术
目前市面上大部分洗衣机等电器设备的控制面板上一般都有显示区域、按键、旋钮三块区域,由于洗衣机的功能越来越多,操作方法也越来越多样化,同时也越来越复杂。大部分旋钮为普通塑料旋钮,用于选择程序,功能及外观单一。随着人们对生活品质及审美要求的提升,旋钮需要提高功能性简化操作难度,并且需要有突破性的外观。
此外,旋钮一直受到进水或水蒸气凝结影响电路及显示的困扰,特别是对于洗衣机这类电器产品来说,经常出现旋钮内部进水损坏的情况,造成不必要的经济损失。
发明内容
本申请旨在至少解决现有技术中存在的技术问题之一。
为此,本申请第一方面提供了一种旋钮组件。
本申请第二方面提供了一种电器设备。
本申请第一方面提供了一种旋钮组件,包括:装配件,装配件包括安装槽和第一挡液部,第一挡液部位于安装槽的外周;控制模组,设置于安装槽;显示模组,与控制模组电连接;旋钮基座,与控制模组相连接;旋钮主体,设置于旋钮基座,位于控制模组的外周,旋钮主体与旋钮基座限定出排液腔;排液部,设置于旋钮基座,排液部连通于排液腔,并用于排出排液腔内的介质, 第一挡液部位于排液部和安装槽之间。
本申请提出的旋钮组件包括装配件、控制模组、显示模组、旋钮基座、旋钮主体和排液部。其中,装配件上设置有安装槽,控制模组设置在安装槽内,保证控制模组的稳定安装;显示模组和旋钮主体电连接于控制模组,旋钮主体可相对于显示模组转动。在旋钮组件使用时,可通过旋转旋钮主体来选择程序,并通过显示模组显示对应的程序参数或运行状态等信息。这样,使得本申请提出的旋钮组件集成控制和显示的功能于一体,旋使得旋钮组件的结构新颖、占用空间小、操作方便,并且可降低应用该旋钮组件的电器设备的成本。
进一步地,在旋钮主体安装到旋钮基座后,旋钮主体与旋钮基座共同限定出了排液腔,并且在旋钮基座上设置了与排液腔相连通的排液部。这样,在旋钮组件使用过程中,进入到旋钮组件内部的液体会首先进入到排液腔内,而排液腔内部的液体可直接通过排液部排出。这样,一方面避免了旋钮组件内部液体存留,可将进入到旋钮组件内部的液体及时排出,保证了旋钮组件内部干燥的环境,另一方面避免了进入到排液腔内部的液体流入到显示模组和控制模组,避免了旋钮组件因进水或进入水雾而损坏。
进一步地,装配件还包括第一挡液部,并且第一挡液部位于安装槽的外周。这样,当旋钮组件装配完毕后,第一挡液部位于旋钮主体和控制模组之间,并可在旋钮主体与控制模组之间挡液,避免外部的液体进入到安装槽的内部与控制模组相接触,进而保证了控制模组周围的环境,避免控制模组进液损坏。并且,本申请通过第一挡液部的设计,可取消相关技术中密封圈的设计,这样可保证旋钮主体与显示模组之间、以及旋钮主体与装配件之间并不直接接触,保证了旋钮本体转动顺畅。
具体地,旋钮组件的装配件和显示模组作为旋钮组件的固定结构使用,而旋钮主体作为旋钮组件的转动结构使用。因此,旋钮主体与显示模组之间、以及旋钮主体与装配件之间存在一定的间隙,以保证转动顺畅且无阻碍。而该旋钮组件可应用于洗衣机或干衣机等电器设备,洗衣机或干衣机等电器设备的使用环境一般为卫生间等湿气较重的空间,液体容易滴落到显示模组上,而在干衣过程中旋钮模组上也容易产生冷凝水,这就导致了旋钮组件存在内部进水的风险。
因此,本申请通过旋钮基座与旋钮主体共同限定出了排液腔,使得进入到旋钮组件内的液体首先会进入到排液腔内,避免了该部分液体在旋钮组件内部流淌漫延。本申请还在旋钮基座上设置有排液部,使得进入到排液腔内部的液体从排液部排出,避免液体长时间留存于排液腔内,保证了旋钮组件内部干燥的环境,同时保证了旋钮组件可及时将排液腔内部的液体排出,保证了旋钮组件的使用寿命。
并且当控制模组安装到安装槽后,第一挡液部可以处于旋钮主体与安装槽之间,这样使得第一挡液部可以为安装槽内的控制模组起到良好的挡液效果,一方面避免旋钮主体表面的液体进入到安装槽内,另一方面避免了旋钮主体与显示模组之间的液体进入到安装槽内,实现了对安装槽的有效挡液,保证了安装槽内部干燥的环境,保证了控制模组的使用寿命。
根据本申请上述技术方案的旋钮组件,还可以具有以下附加技术特征:
在上述技术方案中,装配件包括装配面,安装槽设置于装配面;第一挡液部衔接于安装槽的侧壁,并凸出于装配面。
在该技术方案中,装配件包括装配面。其中,安装槽和第一挡液部均设置在装配面上,控制模组装配到安装槽的内部,旋钮主体设置在装配面的表面,并且,旋钮主体与装配面之间存在一定的距离,以使得转动的旋钮主体与固定的装配面支架并无直接的接触,保证旋钮主体的顺畅转动。
此外,第一挡液部衔接于安装槽的侧壁,并且凸出于装配面设置,这样,第一挡液部可在安装槽的周侧有效挡液,避免外部的液体从装配面与旋钮主体之间流入安装槽内。并且,第一挡液部位于旋钮主体与安装槽之间,第一挡液部衔接于安装槽的侧壁,可有效减小旋钮主体到安装槽的距离,使得旋钮主体与显示模组和控制模组的结构紧凑,有利于实现旋钮组件的小型化设计。
在上述任一技术方案中,第二挡液部,设置于旋钮基座,位于第一挡液部和排液部之间。
在该技术方案中,旋钮组件还包括第二挡液部。其中,第二挡液部设置在旋钮基座上,并且位于都第一挡液部与旋钮主体之间。第一挡液部与第二挡液部的延伸方向不同,第一挡液部设置在装配件上,并朝向上方的旋钮基座延伸,第二挡液部设置在旋钮基座上,并朝向下方的装配件延伸。这样,使得旋钮主 体与安装槽之间存在延伸方向不同的第一挡液部和第二挡液部,第一挡液部与第二挡液部配合使用可形成两道防水,进而避免外部的液体进入到安装槽内,特别是可避免从旋钮主体滴落的液体进入到安装槽内,避免了该部分液体从旋钮主体和装配面之间进入到安装槽内。
在上述任一技术方案中,排液部为排液通道,排液通道形成于第二挡液部和旋钮主体之间。
在该技术方案中,排液部为排液通道,排液通道是由第二挡液部和旋钮主体共同限定出的。排液通道具有一定的排液方向和排液长度。因此,可通过对排液通道的排液方向设置,使得排液通道朝向远离显示模组和控制模组的方向排液,避免从排液通道排出的液体再次进入到旋钮组件的内部。
并且,第一挡液部与第二挡液部设置在排液部和安装槽之间,使得第一挡液部和第二挡液部可在排液部与安装槽之间挡液,进而使得从排液部排出的液体不会进入到安装槽的内部,保证了安装槽内控制模组的使用安全。
在上述任一技术方案中,第一挡液部为环形筋,第二挡液部为环形筋;控制模组位于第一挡液部围成的空间内;第一挡液部位于第二挡液部围成的空间内;旋钮主体位于第二挡液部的外周。
在该技术方案中,第一挡液部与第二挡液部均为环形筋;并且,控制模组位于第一挡液部围成的空间内,第一挡液部位于第二挡液部围成的空间内,旋钮主体位于第二挡液部的外周。这样,从旋钮主体到安装槽的方向上存在至少两道防水结构。并且,旋钮组件安装到电器设备后可能是横向设置的,将第一挡液部与第二挡液部设计为环形筋,可保证各个方向的防水效果,实现全方位防水。
具体地,当旋钮组件安装到电器设备使用时,旋钮组件可能是横向设置的。因此,通过第一挡液部和第二挡液部的设计,使得旋钮组件在横向设置的情况下,仍可良好的挡液,进而保证安装在安装槽内的控制模组的使用安全。
具体地,第一挡液部和第二挡液部用于:在排液部和安装槽之间挡液。第一挡液部与第二挡液部设置在排液部和安装槽之间,使得第一挡液部和第二挡液部可在排液部与安装槽之间挡液,进而使得从排液部排出的液体不会进入到安装槽的内部,保证了安装槽内控制模组的使用安全。在旋钮组件使用过程中, 进入到旋钮组件内部的液体会首先进入到排液腔内,而排液腔内部的液体可直接通过排液部排出。这样,一方面避免了旋钮组件内部液体存留,可将进入到旋钮组件内部的液体及时排出,保证了旋钮组件内部干燥的环境,另一方面避免了进入到排液腔内部的液体流入到显示模组和控制模组,避免了旋钮组件因进水或进入水雾而损坏。
在该技术方案中,进一步地,旋钮主体到装配面的距离,要小于第一挡液部凸出于装配面的高度。也即,在旋钮组件的高度方向上,第一挡液部与旋钮主体存在一部分重叠的部位。这样,从旋钮组件的侧方来看,第一挡液部和第二挡液部配合可完全遮挡旋钮组件内部空间,并且使得从旋钮主体滴落的液体会直接落到第一挡液部的外周,进而使得该部分液体在第一挡液部的阻挡下不会流入安装槽。
特别地,旋钮组件在使用过程中可以是横向放置的,这样由于本申请对第一挡液部凸出高度、以及旋钮主体到装配面的距离的设计,使得即使旋钮组件横向使用,第一挡液部与第二挡液部配合可完全遮挡旋钮组件内部结构,使得第一挡液部和第二挡液部在旋钮组件横向放置的情况下,仍可起到良好的挡液效果,进而避免外部的液体进入到安装槽内,保证了控制模组的使用环境和使用寿命。
在上述任一技术方案中,旋钮组件还包括:第三挡液部,设置于旋钮基座,位于显示模组和排液腔之间。
在该技术方案中,旋钮组件还包括第三挡液部。其中,第三挡液部设置在旋钮基座上,并且与第二挡液部的延伸方向不同,第二挡液部朝向旋钮基座的下方延伸,第三挡液部朝向旋钮基座的上方延伸,并且第三挡液部位于显示模组和旋钮主体之间。这样,第三挡液部可在旋钮主体与显示模组之间挡液。
具体地,第三挡液部作为旋钮组件的转动结构使用,显示模组作为旋钮组件的固定结构使用,因此两者之间存在一定的间隙,以保证旋钮主体顺畅转动。在旋钮主体使用过程中,该间隙内可能会进入液体。因此,在显示模组和旋钮主体之间设置第三挡液部,并通过第三挡液部阻挡该部分液体进入到显示模组所处的位置,以保证显示模组的环境,保证显示模组的使用寿命。
在上述任一技术方案中,旋钮组件还包括:盖板,盖设于显示模组,并覆 盖于第三挡液部;第四挡液部,设置于盖板,位于第三挡液部和排液腔之间。
在该技术方案中,旋钮组件还包括盖板和第四挡液部。其中,盖板盖设在显示模组上,可对显示模组起到一定的保护作用,一方面避免显示模组磕碰,另一方面避免显示模组进水。并且,可在盖板上设置有花纹或颜色等进行装饰,保证了从显示模组释放出的光线最终呈现的状态。
进一步地,第四挡液部设置在盖板的周侧边缘,位于第三挡液部和旋钮主体之间。特别地,第四挡液部与第三挡液部的延伸方向不同。第三挡液部设置在旋钮基座上,并朝向上方延伸;第四挡液部设置在盖板上,并朝向下方延伸。这样,通过第三挡液部和第四挡液部的配合,可在旋钮主体与显示模组之间形成两道防水结构,以进一步提升显示模组的防水效果,并且可实现全方面防水。
在上述任一技术方案中,第四挡液部设置于盖板的周侧边缘,并朝向排液腔的内侧延伸;其中,第四挡液部与旋钮主体之间形成缝隙,缝隙连通于排液腔。
在该技术方案中,第四挡液部设置于盖板的周侧边缘,第四挡液部与旋钮主体之间形成缝隙,该缝隙保证了旋钮主体与盖板之间不会直接接触,保证了转动旋钮主体时两者之间不存在摩擦。并且,缝隙连通于排液腔,这样在旋钮组件使用时,流入缝隙内液体可直接进入在排液腔内,保证了该部分液体不会四处流淌漫延,而该部分液体最终通过排液部排出,保证了显示模组以及其他控制模组的使用环境和私用寿命。
具体地,缝隙、排液腔和排液部构成流道,该流道形成于旋钮组件中固定结构与转动结构之间,并且与旋钮组件的显示模组和控制模组相隔绝,位于显示模组和控制模组的外周。这样,通过流道的设计,一方面保证了可顺畅转动旋钮主体,另一方面保证了旋钮组件的排液效果。并且,无需额外设置复杂结构即可实现上述效果,便于加工和制造,也有利于实现旋钮组件的结构最简化设计。
并且,第四挡液部朝向排液腔的内侧延伸,位于排液腔的内部。这样,进入到盖板与旋钮主体之间的缝隙的液体,会沿着第四挡液部漫延,并在第四挡液部的端部滴落到排液腔内部,避免了进入到盖板与旋钮主体之间的缝隙的液体漫延到显示模组所在的位置。
并且,缝隙形成于第四挡液部与旋钮主体之间,这样使得第三挡液部和第四挡液部位于排液腔与显示模组之间,并可在排液腔与显示模组之间挡液,进而阻挡进入到排液腔内部的液体流向显示模组,保证了显示模组的使用寿命。
在上述任一技术方案中,第三挡液部为环形筋,第四挡液部为环形筋;显示模组位于第三挡液部围成的空间内;第三挡液部位于第四挡液部围成的空间内旋钮主体位于第四挡液部的外周。
在该技术方案中,第三挡液部与第四挡液部均为环形筋;并且,显示模组位于第三挡液部围成的空间内,第三挡液部位于第四挡液部围成的空间内,旋钮主体位于第四挡液部的外周。这样,从旋钮主体到显示模组存在至少两道防水筋,进而存在至少两道防水结构。并且,旋钮组件安装到电器设备后可能是横向设置的,将第三挡液部与第四挡液部设计为环形筋,可保证各个方向的防水效果,实现全方位防水。
在该技术方案中,进一步地,第四挡液部到旋钮基座的距离,小于第三挡液部凸出于旋钮基座的高度。也即,在旋钮组件的高度方向上,第三挡液部与第四挡液部存在一部分重叠的部位。这样,从旋钮组件的侧方快看,显示模组被完全隔离开来,有效保证了对显示模组的防水效果。
特别地,旋钮组件在使用过程中可以是横向放置的,这样由于本申请对第三挡液部凸出高度、以及第四挡液部到旋钮基座的距离的设计,使得即使旋钮组件横向使用,第三挡液部与第四挡液部配合可完全遮挡显示模组,使得第三挡液部和第四挡液部在旋钮组件横向放置的情况下,仍可起到良好的挡液效果,进而避免外部的液体进入到显示模组所在的位置,保证了控制模组的使用环境和使用寿命。
在上述任一技术方案中,旋钮组件还包括:模组支架,连接于显示模组和控制模组;其中,第四挡液部上设置有第一卡扣,第四卡扣连接于模组支架。
在该技术方案中,旋钮组件还包括模组支架,模组支架设置在控制模组上,显示模组设置在模组支架上,以保证显示模组的稳定安装。此外,第四挡液部上设置有第一卡扣,以使得盖体可通过第一卡扣安装在模组支架上,保证了盖体的稳定连接。并且,通过第一卡扣的设置,使得第四挡液部兼具挡液和安装的功能,进而避免了单独设计引流结构、挡液结构和安装结构,有利于简化旋 钮组件的整体结构,并且有利于实现旋钮组件的小型化设计。
在上述任一技术方案中,模组支架上设置有翻边,翻边盖设于第三挡液部,第一卡扣连接于翻边。
在该技术方案中,模组支架上设置有翻边,翻边覆盖在第三挡液部的上方,并且至少位于第三挡液部与旋钮主体之间。这样,通过翻边结构和第三挡液部配合,可进一步提升旋钮组件的防水效果,特别是避免外部的液体越过第三挡液部流向显示模组。并且,第一卡扣连接到翻边上,使得翻边兼具安装盖板以及挡液的作用。
在上述任一技术方案中,第三挡液部上设置有第二卡扣,第二卡扣连接于旋钮基座。
在该技术方案中,第三挡液部上设置有第二卡扣,以使得旋钮主体通过第二卡扣安装在旋钮基座上,保证了旋钮主体的稳定安装,使得用户可通过旋钮主体与旋钮基座转动编码器的转动部,进而选择相应的程序。并且,这使得第三挡液部兼具挡液和安装旋钮主体的作用。
在上述任一技术方案中,旋钮基座为环形基座,并位于模组支架的外周;和/或排液腔为环形腔室,并位于模组支架的外周。
在该技术方案中,旋钮基座为环形基座,并且位于模组支架和显示模组的外周;相应地,排液腔为环形腔室,并且位于模组支架和显示模组的外周。这样,当该旋钮组件横向设置在电器设备上时,进入到旋钮组件一侧的液体可在重力作用下流向旋钮组件的另一侧,并最终从另一侧排出。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点,下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是,在不 冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请,但是,本申请还可以采用其他不同于在此描述的方式来实施,因此,本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图21来描述根据本申请一些实施例提供的旋钮组件和电器设备。其中,图3、图5、图8、图19和图20中箭头表示液体流动方向。
如图1、图2和图3所示,本申请实施例提出了一种旋钮组件,包括:装配件140、控制模组162、显示模组120、旋钮基座106、旋钮主体116和排液部126。其中,装配件140上设置有安装槽142,控制模组162设置在安装槽142内,保证控制模组162的稳定安装;显示模组120和旋钮主体116电连接于控制模组162,旋钮主体116可相对于显示模组120转动。在旋钮组件使用时,可通过旋转旋钮主体116来选择程序,并通过显示模组120显示对应的程序参数或运行状态等信息。这样,使得本申请实施例提出的旋钮组件集成控制和显示的功能于一体,旋使得旋钮组件的结构新颖、占用空间小、操作方便,并且可降低应用该旋钮组件的电器设备的成本。
进一步地,如图3所示,在旋钮主体116安装到旋钮基座106后,旋钮主体116与旋钮基座106共同限定出了排液腔122,并且在旋钮基座106上设置了与排液腔122相连通的排液部126。这样,在旋钮组件使用过程中,进入到旋钮组件内部的液体会首先进入到排液腔122内,而排液腔122内部的液体可直接通过排液部126排出。这样,一方面避免了旋钮组件内部液体存留,可将进入到旋钮组件内部的液体及时排出,保证了旋钮组件内部干燥的环境,另一方面避免了进入到排液腔122内部的液体流入到显示模组120和控制模组162,避免了旋钮组件因进水或进入水雾而损坏。
进一步地,如图3所示,装配件140还包括第一挡液部144,并且第一挡液部144位于安装槽142的外周。这样,当旋钮组件装配完毕后,第一挡液部144位于旋钮主体116和控制模组162之间,并可在旋钮主体116与控制模组162之间挡液,避免外部的液体进入到安装槽142的内部与控制模组162相接触,进而保证了控制模组162周围的环境,避免控制模组162进液损坏。并且, 本申请实施例通过第一挡液部144的设计,可取消相关技术中密封圈的设计,这样可保证旋钮主体116与显示模组120之间、以及旋钮主体116与装配件140之间并不直接接触,保证了旋钮本体转动顺畅。
具体地,如图3所示,旋钮组件的装配件140和显示模组120作为旋钮组件的固定结构使用,而旋钮主体116作为旋钮组件的转动结构使用。因此,旋钮主体116与显示模组120之间、以及旋钮主体116与装配件140之间存在一定的间隙,以保证转动顺畅且无阻碍。而该旋钮组件可应用于洗衣机或干衣机等电器设备,洗衣机或干衣机等电器设备的使用环境一般为卫生间等湿气较重的空间,液体容易滴落到显示模组120上,而在干衣过程中旋钮模组上也容易产生冷凝水,这就导致了旋钮组件存在内部进水的风险。
因此,本申请实施例通过旋钮基座106与旋钮主体116共同限定出了排液腔122,使得进入到旋钮组件内的液体首先会进入到排液腔122内,避免了该部分液体在旋钮组件内部流淌漫延。本申请实施例还在旋钮基座106上设置有排液部126,使得进入到排液腔122内部的液体从排液部126排出,避免液体长时间留存于排液腔122内,保证了旋钮组件内部干燥的环境,同时保证了旋钮组件可及时将排液腔122内部的液体排出,保证了旋钮组件的使用寿命。
并且,如图3所示,当控制模组162安装到安装槽142后,第一挡液部144可以处于旋钮主体116与安装槽142之间,这样使得第一挡液部144可以为安装槽142内的控制模组162起到良好的挡液效果,一方面避免旋钮主体116表面的液体进入到安装槽142内,另一方面避免了旋钮主体116与显示模组120之间的液体进入到安装槽142内,实现了对安装槽142的有效挡液,保证了安装槽142内部干燥的环境,保证了控制模组162的使用寿命。
在本申请实施例提出的旋钮组件中,进一步地,如图3所示,装配件140包括装配面160。其中,安装槽142和第一挡液部144均设置在装配面160上,控制模组162装配到安装槽142的内部,旋钮主体116设置在装配面160的表面,并且,旋钮主体116与装配面160之间存在一定的距离,以使得转动的旋钮主体116与固定的装配面160支架并无直接的接触,保证旋钮主体116的顺畅转动。
此外,如图3所示,第一挡液部144衔接于安装槽142的侧壁,并且凸 出于装配面160设置,这样,第一挡液部144可在安装槽142的周侧有效挡液,避免外部的液体从装配面160与旋钮主体116之间流入安装槽142内。并且,第一挡液部144位于旋钮主体116与安装槽142之间,第一挡液部144衔接于安装槽142的侧壁,可有效减小旋钮主体116到安装槽142的距离,使得旋钮主体116与显示模组120和控制模组162的结构紧凑,有利于实现旋钮组件的小型化设计。
在本申请实施例提出的旋钮组件中,进一步地,如图3所示,旋钮组件还包括第二挡液部128。其中,第二挡液部128设置在旋钮基座106上,并且位于都第一挡液部144与旋钮主体116之间。
如图3所示,第一挡液部144与第二挡液部128的延伸方向不同,第一挡液部144设置在装配件140上,并朝向上方的旋钮基座106延伸,第二挡液部128设置在旋钮基座106上,并朝向下方的装配件140延伸。这样,使得旋钮主体116与安装槽142之间存在延伸方向不同的第一挡液部144和第二挡液部128,第一挡液部144与第二挡液部128配合使用可形成两道防水,进而避免外部的液体进入到安装槽142内,特别是可避免从旋钮主体116滴落的液体进入到安装槽142内,避免了该部分液体从旋钮主体116和装配面160之间进入到安装槽142内。
在本申请实施例提出的旋钮组件中,进一步地,如图4、图5、图6、图7和图8所示,排液部126为排液通道,排液通道是由第二挡液部128和旋钮主体116共同限定出的。排液通道具有一定的排液方向和排液长度。因此,可通过对排液通道的排液方向设置,使得排液通道朝向远离显示模组120和控制模组162的方向排液,避免从排液通道排出的液体再次进入到旋钮组件的内部。
并且,如图3所示,第一挡液部144与第二挡液部128设置在排液部126和安装槽142之间,使得第一挡液部144和第二挡液部128可在排液部126与安装槽142之间挡液,进而使得从排液部126排出的液体不会进入到安装槽142的内部,保证了安装槽142内控制模组162的使用安全。
此外,排液部126也可直接采用排液口,并且排液口贯穿于旋钮基座106设置。
具体地,如图12、图13和图14所示,排液部126为第二挡液部128外周开设的导水槽,并在第二挡液部128的周向间隔设置,第二挡液部128的外壁与旋钮主体116的内壁是紧贴着的,仅导水槽的位置有开口,这样外部的液体不容易进入到排液腔122的内部,而排液腔122内的液体又可以通过排液部126流出,很好的兼具了挡液和排液的作用。
在本申请实施例提出的旋钮组件中,进一步地,如图3、图12、图13和图14所示,第一挡液部144与第二挡液部128均为环形筋;并且,控制模组162位于第一挡液部144围成的空间内,第一挡液部144位于第二挡液部128围成的空间内,旋钮主体116位于第二挡液部128的外周。这样,从旋钮主体116到安装槽142的方向上存在至少两道防水。并且,旋钮组件安装到电器设备后可能是横向设置的,将第一挡液部144与第二挡液部128设计为环形筋,可保证各个方向的防水效果,实现全方位防水。
具体地,当旋钮组件安装到电器设备使用时,旋钮组件可能是横向设置的。因此,通过第一挡液部144和第二挡液部128的设计,使得旋钮组件在横向设置的情况下,仍可良好的挡液,进而保证安装在安装槽142内的控制模组162的使用安全。
在本申请实施例提出的旋钮组件中,进一步地,如图3所示,第一挡液部144和第二挡液部128用于:在排液部126和安装槽142之间挡液。第一挡液部144与第二挡液部128设置在排液部126和安装槽142之间,使得第一挡液部144和第二挡液部128可在排液部126与安装槽142之间挡液,进而使得从排液部126排出的液体不会进入到安装槽142的内部,保证了安装槽142内控制模组162的使用安全。
如图3和图8所示,在旋钮组件使用过程中,进入到旋钮组件内部的液体会首先被进入到排液腔122内,而排液腔122内部的液体可直接通过排液部126排出。这样,一方面避免了旋钮组件内部液体存留,可将进入到旋钮组件内部的液体及时排出,保证了旋钮组件内部干燥的环境,另一方面避免了进入到排液腔122内部的液体流入到显示模组120和控制模组162,避免了旋钮组件因进水或进入水雾而损坏。
在本申请实施例提出的旋钮组件中,进一步地,如图3所示,旋钮主 体116到装配面160的距离,要小于第一挡液部144凸出于装配面160的高度。也即,在旋钮组件的高度方向上,第一挡液部144与旋钮主体116存在一部分重叠的部位。这样,从旋钮组件的侧方来看,第一挡液部144和第二挡液部128配合可完全遮挡旋钮组件内部空间,并且使得从旋钮主体116滴落的液体会直接落到第一挡液部144的外周,进而使得该部分液体在第一挡液部144的阻挡下不会流入安装槽142。
特别地,如图1和图2所示,旋钮组件在使用过程中可以是横向放置的,这样由于本申请对第一挡液部144凸出高度、以及旋钮主体116到装配面160的距离的设计,使得即使旋钮组件横向使用,第一挡液部144与第二挡液部128配合可完全遮挡旋钮组件内部结构,使得第一挡液部144和第二挡液部128在旋钮组件横向放置的情况下,仍可起到良好的挡液效果,进而避免外部的液体进入到安装槽142内,保证了控制模组162的使用环境和使用寿命。
在本申请实施例提出的旋钮组件中,进一步地,如图12、图13和图14所示,旋钮组件还包括第三挡液部130。其中,第三挡液部130设置在旋钮基座106上;并且,如图3、图5和图8所示,第三挡液部130与第二挡液部128的延伸方向不同,第二挡液部128朝向旋钮基座106的下方延伸,第三挡液部130朝向旋钮基座106的上方延伸,并且第三挡液部130位于显示模组120和旋钮主体116之间。这样,第三挡液部130可在旋钮主体116与显示模组120之间挡液。
具体地,如图6、图7和图8所示,旋钮主体116作为旋钮组件的转动结构使用,显示模组120作为旋钮组件的固定结构使用,因此两者之间存在一定的间隙,以保证旋钮主体116顺畅转动。在旋钮主体116使用过程中,该间隙内可能会进入液体。因此,在显示模组120和旋钮主体116之间设置第三挡液部130,并通过第三挡液部130阻挡该部分液体进入到显示模组120所处的位置,以保证显示模组120的环境,保证显示模组120的使用寿命。
在本申请实施例提出的旋钮组件中,进一步地,如图4和图5所示,旋钮组件还包括盖板118和第四挡液部132。其中,盖板118盖设在显示模组120上,可对显示模组120起到一定的保护作用,一方面避免显示模组120磕碰,另一方面避免显示模组120进水。并且,可在盖板118上设置有花纹或颜 色等进行装饰,保证了从显示模组120释放出的光线最终呈现的状态。
进一步地,第四挡液部132设置在盖板118的周侧边缘,位于第三挡液部130和旋钮主体116之间。特别地,第四挡液部132与第三挡液部130的延伸方向不同。第三挡液部130设置在旋钮基座106上,并朝向上方延伸;第四挡液部132设置在盖板118上,并朝向下方延伸。这样,通过第三挡液部130和第四挡液部132的配合,可在旋钮主体116与显示模组120之间形成两道防水结构,以进一步提升显示模组120的防水效果,并且可实现全方面防水。
在本申请实施例提出的旋钮组件中,进一步地,第四挡液部132设置于盖板118的周侧边缘,第四挡液部132与旋钮主体116之间形成缝隙124,该缝隙124保证了旋钮主体116与盖板118之间不会直接接触,保证了转动旋钮主体116时两者之间不存在摩擦。并且,缝隙124连通于排液腔122,这样在旋钮组件使用时,流入缝隙124内液体可直接被进入在排液腔122内,保证了该部分液体不会四处流淌漫延,而该部分液体最终通过排液部126排出,保证了显示模组120以及其他控制模组162的使用环境和私用寿命。
具体地,旋钮组件的装配件140和显示模组120作为旋钮组件的固定结构使用,旋钮主体116作为旋钮组件的转动结构使用,缝隙124、排液腔122和排液部126构成流道,该流道形成于旋钮组件中固定结构与转动结构之间,并且与旋钮组件的显示模组120和控制模组162相隔绝,位于显示模组120和控制模组162的外周。这样,通过流道的设计,一方面保证了可顺畅转动旋钮主体116,另一方面保证了旋钮组件的排液效果。并且,无需额外设置复杂结构即可实现上述效果,便于加工和制造,也有利于实现旋钮组件的结构最简化设计。
并且,第四挡液部132朝向排液腔122的内侧延伸,位于排液腔122的内部。这样,进入到盖板118与旋钮主体116之间的缝隙124的液体,会沿着第四挡液部132漫延,并在第四挡液部132的端部滴落到排液腔122内部,避免了进入到盖板118与旋钮主体116之间的缝隙124的液体漫延到显示模组120所在的位置。
并且,缝隙124形成于第四挡液部132与旋钮主体116之间,这样使得第三挡液部130和第四挡液部132位于排液腔122与显示模组120之间,并可在 排液腔122与显示模组120之间挡液,进而阻挡进入到排液腔122内部的液体流向显示模组120,保证了显示模组120的使用寿命。
在本申请实施例提出的旋钮组件中,进一步地,如图3和图5所示,第三挡液部130与第四挡液部132均为环形筋;并且,显示模组120位于第三挡液部130围成的空间内,第三挡液部130位于第四挡液部132围成的空间内,旋钮主体116位于第四挡液部132的外周。这样,从旋钮主体116到显示模组120存在至少两道防水筋,进而存在至少两道防水结构。并且,旋钮组件安装到电器设备后可能是横向设置的,将第三挡液部130与第四挡液部132设计为环形筋,可保证各个方向的防水效果,实现全方位防水。
在本申请实施例提出的旋钮组件中,进一步地,如图3和图5所示,第四挡液部132到旋钮基座106的距离,小于第三挡液部130凸出于旋钮基座106的高度。也即,在旋钮组件的高度方向上,第三挡液部130与第四挡液部132存在一部分重叠的部位。这样,从旋钮组件的侧方快看,显示模组120被完全隔离开来,有效保证了对显示模组120的防水效果。
特别地,如图1和图2所示,旋钮组件在使用过程中可以是横向放置的,这样由于本申请实施例对第三挡液部130凸出高度、以及第四挡液部132到旋钮基座106的距离的设计,使得即使旋钮组件横向使用,第三挡液部130与第四挡液部132配合可完全遮挡显示模组120,使得第三挡液部130和第四挡液部132在旋钮组件横向放置的情况下,仍可起到良好的挡液效果,进而避免外部的液体进入到显示模组120所在的位置,保证了控制模组162的使用环境和使用寿命。

在本申请实施例提出的旋钮组件中,进一步地,如图9、图10和图11所示,模组支架108上设置有翻边146,翻边146覆盖在第三挡液部130的上方,并且至少位于第三挡液部130与旋钮主体116之间。这样,通如图8所示,过翻边146和第三挡液部130配合,可进一步提升旋钮组件的防水效果,特别是避免外部的液体越过第三挡液部130流向显示模组120。并且,第一卡扣148连接到翻边146上,使得翻边146兼具安装盖板118以及挡液的作用。
在本申请实施例提出的旋钮组件中,进一步地,如图15和图16所示,第三挡液部130上设置有第二卡扣150,以使得旋钮主体116通过第二卡扣150安装在旋钮基座106上,保证了旋钮主体116的稳定安装,使得用户可通过旋钮主体116与旋钮基座106转动编码器104的转动部134,进而选择相应的程序。并且,这使得第三挡液部130兼具挡液和安装旋钮主体116的作用。

在该实施例中,进一步地,如图3、图5和图8所示,旋钮基座106上设置有第三挡液部130,第三挡液部130朝向旋钮基座106的上方延伸,并且位于显示模组120和旋钮主体116之间。这样,第三挡液部130可在旋钮主体116与显示模组120之间挡液,特别是可以阻挡排液腔122内部的液体进入到显示模组120所在的位置,以保证显示模组120的环境,保证显示模组120的使用寿命。
此外,如图3、图5和图8所示,盖板118的周侧边缘设置有第四挡液部132,第四挡液部132与旋钮主体116之间形成了缝隙124,第四挡液部132位于第三挡液部130和缝隙124之间。这样,通过第三挡液部130和第四挡液部132的配合,可在缝隙124与显示模组120之间形成双重防水,以进一步提升显示模组120的防水效果,并且可实现全方面防水,保证了显示模组120的使用寿命。

具体地,目前市面上大部分洗衣机的控制面板上一般都有显示区域、按键、旋钮三块区域,由于洗衣机的功能越来越多,操作方法也越来越多样化,同时也越来越复杂。大部分旋钮为普通塑料旋钮,用于选择程序,功能及外观单一。 随着人们对生活品质及审美要求的提升,旋钮需要提高功能性简化操作难度,并且需要有突破性的外观。
为达到简化操作方式及操作界面,增加旋钮实用性及美观性的需求,本申请实施例设计了一款集显示功能和程序选择功能于一体的旋钮组件,该旋钮外观新颖,操作简单。
如图17所示,旋钮组件包括编码开关和盖板118;编码开关包括可旋转部分(旋钮基座106、旋钮主体116、旋钮饰件156)、编码器104及其主控板102、固定显示部分(显示模组120、模组支架108、盖板118)。显示模组120包含显示显示板110、显示支架112、显示膜114;编码器104作为中介,关联旋转部分和固定显示部分。
具体地,如图18所示,编码器104安装在主控板102上,通过针脚点焊在一起,编码器104的转动,主控板102上的程序相应被触发。如图8和图14所示,旋钮基座106通过周向分布的第五卡扣158固定在编码器104的转动部134。如图20所示,旋钮主体116通过内侧的第二卡扣150固定在旋钮基座106上。如图15、图16和图19所示,旋钮饰件156起到指示程序功能,其通过第三卡扣152固定在旋钮主体116上。如图19示,模组支架108通过周向分布的第四卡扣154固定在编码器104的固定部136。整个部分是固定不动的,这样在旋转旋钮主体116时,显示部分就不会动。如图21所示,显示模组120放置在模组支架108中,显示板110安装在显示支架112的背面,通过封胶固定;显示膜114粘贴在显示支架112正面,显示膜114上印刷有需要显示的字符及图案,当进行程序选择时,显示板110上的发光二级管被点亮,透过显示支架112及显示膜114显示出来。盖板118盖在显示模组120上,通过第一卡扣148安装在模组支架108上;具体地,第一卡扣148设置在第四挡液部132上,进而使得第四挡液部132兼具引流、挡液和安装固定的作用。盖板118一般有花纹或颜色进行装饰。保证了从显示模组120释放出的光线最终呈现在旋钮组件上的状态。
特别的,此类外观件一直受到进水或水蒸气凝结影响电路及显示的困扰,因此,本申请实施例对旋钮组件的排水和挡水进行了改进。
其中,如图3、图5和图8所示,水流可能旋钮组件正面盖板118与旋钮 主体116之间的缝隙124进入内部,也可通过与装配件140与旋钮主体116之间的缝隙124进入。本申请实施例首先在盖板118的边缘设置第四挡液部132,在旋钮基座106上的配合使用第三挡液部130,从而减少了水流从旋钮组件正面进入内部的可能性。另外,旋钮基座106的四周也分布了许多排液部126,引导水流从排液部126流出。其次,旋钮基座106的第二挡液部128装配件140上的第一挡液部144,也阻断了外部侧面水流进入旋钮组件内部。
本申请实施例中,旋钮组件实现了程序选择功能及显示功能于一体的效果,使得应用该旋钮组件的电器设备显示区域减小,使原有显示区域有了更多的设计空间;通过对旋钮组件内部结构改进(第一挡液部144、第二挡液部128、第三挡液部130、第四挡液部132和排液部126),有效的保证了旋钮组件的防水性和排水性。
