Description

电饭煲及其内盖组件 技术领域
本发明涉及电饭煲领域，具体地涉及一种内盖组件。此外，本发明还涉及具有所述内盖组件的电饭煲。
背景技术
为方便清洗，电饭煲的内盖通常设置为可拆卸连接于外盖上。
其中，一种常见的可拆卸连接方式为通过硅胶把手卡入显示板盖的向下延伸的卡接支柱上。具体而言，硅胶把手的外周缘卡接至内盖本体的中心孔中，朝向外盖推动内盖本体，即可使得硅胶把手套接在卡接支柱上，并通过卡接支柱底端的凸起台阶卡止；在拆卸时，朝向远离外盖的方向拉拔硅胶把手，使其与卡接支柱分离。
在该拆装过程中，硅胶把手越过卡接支柱的的凸起台阶完成卡接时完全依赖操作者手感，不能准确确定是否安装到位。并且，在使用过后进行拆卸时，硅胶把手受热变软，在拉力作用下发生变形，与卡接支柱的凸起台阶非正常接合，使得难以顺利拔出。此外，硅胶把手可以从内盖本体拆下，在使用过程中容易装反，设计不够人性化。
另一种常见的可拆卸连接方式为螺纹连接。典型地，外盖内侧中心形成有螺柱，内盖本体自身形成有螺孔或利用连接至螺柱的螺母固定。在拆装过程中，要求操作者双手作业，一手按着内盖(防止掉落)，另一手拧动螺母，费时费力，操作困难。
发明内容
本发明的目的是为了克服现有技术存在的拆装不便问题，提供一种内 盖组件，该内盖组件能够方便地连接至外盖组件上并从该外盖组件拆下。
为了实现上述目的，本发明一方面提供一种内盖组件，包括内盖本体和用于卡接至外盖组件上的卡扣，该卡扣滑动安装于所述内盖本体上，并连接有用于沿滑动方向将所述卡扣偏压至卡接位置的复位弹簧，所述卡扣的两侧对应形成有导入面和导出面，该导入面和导出面沿朝向所述卡接位置的滑动方向彼此靠近地相对于所述卡扣的滑动平面倾斜延伸，以能够通过轴向拉压所述内盖本体而将所述内盖组件卡接至所述外盖组件或从该外盖组件拆下。
优选地，所述内盖本体上安装有环绕所述内盖本体上的通孔均匀布置并能够彼此靠近地滑动至所述卡接位置的多个所述卡扣。
优选地，多个所述卡扣环绕所述内盖本体的板面中心布置。
优选地，所述内盖本体上固定设置有把手。
优选地，所述把手为通过铆钉铆接至所述内盖本体上的塑料件，并且/或者，所述把手与所述卡扣形成并布置为具有共同的中心轴线。
优选地，所述卡扣通过所述把手安装于所述内盖本体上，且所述把手形成有容纳所述卡扣和所述复位弹簧的容纳空间。
优选地，所述卡扣形成有位于所述导入面和导出面之间以能够在所述卡接位置贴合至所述外盖组件上的触碰面，并且/或者，所述卡扣形成有用于限定极限滑动位置的限位面，该限位面朝向所述导入面和导出面所在的一侧。
优选地，所述卡扣形成有弹簧套杆，所述复位弹簧套设于该弹簧套杆上并朝向所述卡接位置偏压所述卡扣。
本发明第二方面提供一种具有上述内盖组件的电饭煲。
本发明第三方面提供一种电饭煲，包括外锅、内锅、加热组件、外盖组件以及内盖组件，所述外盖组件上设置有具有凸起台阶的卡接支柱，所述内盖组件包括内盖本体和用于卡接至所述卡接支柱上的卡扣，该卡扣滑 动安装于所述内盖本体上，并连接有用于沿滑动方向将所述卡扣偏压至卡接位置的复位弹簧，所述凸起台阶和所述卡扣中的至少一者上形成有导入面和导出面，该导入面和导出面设置为相对于所述卡扣的滑动平面倾斜延伸，以能够通过轴向拉压所述内盖本体而使得所述卡扣滑动为与所述卡接支柱卡接或分离。
通过上述技术方案，利用卡扣两侧的导入面和导出面，在拉压内盖本体时可以将轴向作用力转化为反作用于卡扣上的沿其滑动方向的作用力，由此驱动卡扣克服复位弹簧的偏压作用力而从卡接位置滑动至允许与其卡接的外盖组件上的如凸起台阶通过的拆装位置，从而方便地实施拆装。在安装过程中，通过卡扣碰撞如卡接支柱的外周面发出“咔嗒”声，能够提示操作者内盖组件已安装到位。
附图说明
附图是用来提供对本发明的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本发明，但并不构成对本发明的限制。在附图中：
图1是根据本发明一种优选实施方式的电饭煲的剖视结构示意图；
图2是图1中内盖组件的剖视结构示意图；
图3是图2中内盖组件上的卡扣的结构示意图；
图4是图1中显示板盖的半剖结构示意图。
具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
图1所示为根据本发明一种优选实施方式的电饭煲，包括外锅1、内锅 2、加热组件3、外盖组件4和内盖组件5等。内锅2设置于外锅1中，并可以由加热组件3加热其中的食物。内盖组件5连接至外盖组件4的内侧，并在图示关闭位置通过密封圈56(结合图2)与内锅2密封接触。
为便于理解本发明的技术方案，首先结合图1和图4对电饭煲中一种典型的外盖组件4进行说明。具体地，外盖组件4可以包括显示板41和将该显示板41与内盖组件5隔开的显示板盖42。为便于连接内盖组件5，显示板盖42设置有沿远离显示板41方向延伸的卡接支柱43，该卡接支柱43的端部径向凸起形成为凸起台阶44。由此，该台阶部44可以具有台阶导向面441和台阶配合面442。
应当理解的是，尽管随后将以该外盖组件4为连接对象详细说明本发明的内盖组件5，通过设置于显示板盖42上的卡接支柱43与内盖组件5上的卡扣52配合完成拆装，但与所述内盖组件5配合的卡接结构还可以设置于外盖组件4的其他部件上或形成为其他结构形式。
结合图2和图3所示，根据本发明一种优选实施方式的内盖组件5，可以方便卡接至图4所示卡接支柱43，以用于图1所示电饭煲中。具体地，该内盖组件5包括内盖本体51、卡扣52、复位弹簧53等。卡扣52滑动安装于内盖本体51上，并被复位弹簧53偏压为具有朝向其卡接位置(即图示靠近内盖本体51的中心轴线的位置)滑动的趋势。
该卡扣52的上侧形成有导入面52a，下侧形成有导出面52b。该导入面52a和导出面52b沿朝向其相邻的自由端方向相对于内盖本体51的板面方向倾斜地延伸(可以为弧面或倾斜平面)，由此二者朝向所述自由端彼此靠近。在此情形下，在安装内盖组件5时，可以朝向外盖组件4按压该内盖组件5，导入面52a对卡接支柱43的下端面和台阶导向面441(结合图4)施加垂直并远离该导入面52a的倾斜作用力，同时，卡接支柱43对导入面52a具有反向作用力，该反向作用力具有沿远离卡扣52的卡接位置方向的分力。由此，能够克服复位弹簧53的弹力，使得卡扣52从卡接位置滑动 至拆装位置，即允许卡接支柱43上的凸起台阶44越过卡扣52的位置。
之后，在复位弹簧53作用下，卡扣52的自由端(如碰撞面52c)碰撞卡接支柱43的位于凸起台阶44上方的外周面，快速复位至其卡接位置，发出“咔嗒”声，能够提示操作者内盖组件5已安装到位。此时，卡扣52的导出面52b与凸起台阶44上侧的台阶配合面442配合卡止，阻止内盖组件5从外盖组件4脱离。
使用完成后，沿远离外盖组件4的方向轴向拉动内盖本体51，卡扣52的导出面52b对卡接支柱43上的台阶配合面442施加垂直并远离该导出面52b的倾斜作用力，同时，台阶配合面442对导出面52b具有反向作用力，该反向作用力具有沿远离卡扣52的卡接位置方向的分力。由此，能够克服复位弹簧53的弹力，使得卡扣52从卡接位置滑动至拆装位置，允许卡接支柱43上的凸起台阶44越过卡扣52的位置，从而从外盖组件4拆下内盖组件5。
在上述过程中，利用卡扣52两侧的导入面52a和导出面52b，将轴向作用力转化为反作用于卡扣52上的沿其滑动方向的作用力，从而方便地实施拆装。在安装过程中，通过卡扣52碰撞如卡接支柱43的外周面发出“咔嗒”声，能够提示操作者内盖组件已安装到位。
在上述优选实施方式中，台阶配合面442的倾斜度优选为小于卡扣52的导出面52b的倾斜度，尽管在一定程度上减弱了内盖组件5与外盖组件4的卡接强度，但能够便于通过轴向拉动内盖组件5而实施拆卸，避免拆卸困难。至于卡接强度因倾斜角度关系减弱，可以适当提高复位弹簧53的劲度系数，避免内盖组件5不合理地从外盖组件4分离。
在本发明的另一种优选实施方式中，还可以将用于作用力方向转换的导入面52a和导出面52b形成在卡接支柱43的凸起台阶44上，使得该凸起台阶44形成为两头小、中间大的纺锤形形状。在此情形下，卡扣52的上、下两侧可以不具有倾斜面，同样可以通过轴向拉压内盖本体51而拆装 内盖组件5。
继续参照图2所示，在该优选实施方式中，内盖本体51形成有中心孔，环绕该中心孔设置有至少两个卡扣52，这些卡扣52能够同步朝向或远离中心孔的轴线滑动，以在卡接位置与卡接支柱的不同周向部位接合。在此情形下，外盖组件上仅需设置一个卡接支柱；对应地，内盖组件5具有一组沿圆周均匀布置的卡扣52。
可选地，这种沿圆周对应均匀布置的卡扣52可以在内盖本体51上设置有多组，即在内盖本体51的不同位置设置多个如图2中位于板面中心的结构，并分别与相应的卡接支柱卡接。
通过上述设置，卡接支柱可以对卡扣52产生均匀的反作用力，在驱动卡扣52卡接位置向拆装位置滑动时更稳定，避免轴向拉压内盖本体51时难以合理施力而导致掉落和碰撞。
其中，为便于施加轴向拉压力，内盖本体51上可以固定设置有把手54。例如，把手54可以通过铆钉55铆接至内盖本体51上。由此，在使用过程中不会将把手54从内盖本体51拆下，避免装反。所述把手54可以为塑料件，包括塑胶材质和电木材质等。其中，为提高施力效率，把手54与卡扣52可以形成、布置为具有共同的中心轴线。例如，在图示实施方式中，把手54为回转件，卡扣52具有用于贴合卡接支柱43的弧形触碰面52c，该触碰面52c的曲率中心位于把手54的回转轴线上，或者，圆周布置的多个卡扣52环绕的中心轴线与把手54的回转轴线重合。由此，能够以较小的拉力，将内盖组件5从外盖组件4拆下。
卡扣52可以以多种适宜方式滑动安装于内盖本体51上。在图示实施方式中，把手54的朝向内盖本体51的一侧形成有容纳空间，卡扣52和复位弹簧53容纳于该容纳空间中，并在上侧由内盖本体51限位。由此，避免设置卡扣52导致内盖本体51结构复杂，且便于内盖组件5的组装。
在本发明中，卡扣52可以形成为多种适当的结构，只要其能够卡接至 外盖组件4上，均属于本发明的构思范围。在一种优选实施方式中，如图3所示，其导入面52a和导出面52b之间形成有触碰面52c，由此可以通过与卡接支柱43碰撞而产生“咔嗒”声，提示操作者已安装到位。通过设置该触碰面52c，使之与卡接支柱43的外周面匹配，可以避免多次碰撞导致的损坏，可靠性较高。
卡扣52还可以形成有限位面52d，该限位面52d朝向导入面52a和导出面52b所在的一侧，用于通过与如内盖本体51上的对应结构配合而限定其朝向卡接位置的极限滑动位置，避免装配误差导致的不合理脱落。
图示卡扣52在两翼分别形成有限位面52d，两翼之间形成有弹簧套杆52e，复位弹簧53套设于该弹簧套设于该弹簧套杆52e上并朝向卡接位置偏压卡扣，由此，提高其偏压作用力的方向稳定性。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于此。在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本发明所公开的内容，均属于本发明的保护范围。
