请一并参阅图1～图7，本发明实施方式的旋钮10能够应用于本发明实施方式的家用电器100。家用电器100例如为微波炉、烤箱、电磁炉或者音响等。家用电器100包括本体20、壳件30、控制面板40和门体50。壳件30安装于本体20。控制面板40设置于壳件30，并由壳件30隐藏。具体地，控制面板40通过第一紧固件41固定于壳件30(见图7)，第一紧固件41例如为螺钉。旋钮10安装于壳件30并由壳件30露出，以供用户进行操作。
其中，本体20基本呈矩形体状。本体20开设有腔室(图未示出)。门体50可转动地安装于本体20以打开或关闭腔室。壳件30和门体50位于本体20的同一侧。其中门体50上可设置把手51以便于用户操作。
需要说明的是，旋钮10的数目可根据具体情况进行设置，并且旋钮10在壳件30上的安装方式可根据具体情况进行设置。请结合图11，壳件30开设有第一安装槽301。旋钮10部分地安装于第一安装槽301。同时把手51的安装方式也可以根据具体情况进行设置，门体50上也可不设置把手51(如图4所示)。
例如，在图1所示的例子中，旋钮10的数目为一个，并且旋钮10安装于壳件30的上端。把手51竖向安装于门体50。在图2所示的例子中，旋钮10的数目为两个，并且两个旋钮10间隔设置。把手51竖向安装于门体50。两个旋钮10位于门体50的同一侧。在图3所示的例子中，旋钮10的数目为两个，并且两个旋钮10间隔设置。把手51横向安装于门体50。在图4所示的例子中，旋钮10的数目为两个，并且两个旋钮10间隔设置。
请结合图5及图11及图14，旋钮10包括基座11、旋钮部12、显示组件13、第一电路板14和开关15。基座11安装于第一电路板14。旋钮部12转动地安装于基座11。显示组件13至少部分地设在旋钮部12内。基座11安装于第一电路板14。开关15安装于第一电路板14。旋钮部12能够相对于显示组件13转动。即，在旋钮部12转动时，显示组件13是静止的。其中，第一电路板14例如为印刷(PCB)电路板。
请结合图11，旋钮部12包括旋钮壳121、连接件122和感应部123。旋钮壳121由壳件30的外表面露出。旋钮部12被配置成在旋钮部12转动时感应部123输出旋钮部12转动的信号。其中，可以理解，感应部可以为触摸式感应部，例如感应部可包括多个感应部件(感应部件可为插针)，手指在旋钮侧面触碰，引起感应部件的电容值变化，以输出旋钮部转动的不同信号。可以理解，感应部可包括用于识别旋钮旋转动作的感应编码器，感应部通过感应编码器输出旋钮部转动的信号。下面对本实施方式的旋钮部12的结构作进一步说明。
请结合图11至图13，旋钮壳121开设有第一开口1210。感应部123设在第一电路板14并与第一电路板14电性连接。感应部123包括转动部1231和固定部1232。旋钮壳121连接转动部1231。固定部1232安装在基座11。旋钮壳121转动时带动转动部1231相对于固定部1232转动。连接件122连接旋钮壳121和转动部1231。其中，旋钮壳121的形状可根据具体情况进行设置，在图12所示的例子中，旋钮壳121基本呈圆柱体状。旋钮壳121罩设连接件122。另需要说明的是，本实施方式的旋钮部12可不设置连接件122。当然，连接件122的设置能够增加旋钮10的可设置空间。
请结合图16至图22，为了提高转动部1231连接连接件122的稳定性，转动部1231包括环形件1233。环形件1233的外侧壁开设有凹槽1234。连接件122呈环形。连接件122的内侧壁凸设有凸件1221。凸件1221卡设凹槽1234以使连接件122与环形件1233配合连接。当然，可以理解，环形件的外侧壁可凸设有凸件，而连接件的内侧壁开设有凹槽，凸件卡设凹槽以使连接件与环形件配合连接。这可根据具体情况进行设置。
可以理解，固定部1232可以为编码器(例如磁性编码器)，环形件1233可以构成编码器的转动的外圈。其中，编码器的类型可根据具体情况选择。这样编码器的外圈随着旋钮壳121实现相应的转动操作，以实现其相应设定的功能。
为了便于转动部1231连接连接件122，请结合图20及图21，连接件122形成有第一连接臂1222。第一连接臂1222的内侧面凸设有凸件1221。第一连接臂1222具有弹性。其中，第一连接臂1222可采用柔性材料制成。当然，可以理解，连接件122可采用塑料材料制成。另外，第一连接臂1222的数目可以为多个，并且多个第一连接臂1222可沿连接件122的周向间隔分布，并且每个第一连接臂1222均凸设有凸件1221。形成的凸件1221的数目与凹槽1234的数目对应，即多个凸起件1221分别卡设多个凹槽1234。需要说明的是，第一连接臂1222的数目可根据具体情况进行设置。
在图16所示的例子中，连接件122包括旋钮配合端1223和自旋钮配合端1223向下延伸的第一连接端1224。旋钮壳121与旋钮配合端1223配合连接。第一连接端1224的侧壁形成第一连接臂1222。其中，旋钮配合端1223呈环形，旋钮壳121套设旋钮配合端1223。第一连接端1224呈环形。旋钮配合端1223的尺寸可设置得大于第一连接端1224的尺寸。
为了使旋钮10整体结构更紧凑，旋钮部12开设有贯穿连接件122和旋钮壳121的容置腔120(见图13及图14)。显示组件13至少部分地位于容置腔120内。
请结合图11，显示组件13包括显示部131、安装部132和柔性电路板135。显示部131安装于安装部132。安装部132安装于基座11。安装部132连接显示部131和基座11。显示部131通过旋钮部12进行显示。具体地，显示部131通过旋钮部12的中部进 行显示。显示部131由第一开口1210露出。柔性电路板135与显示部131电性连接。柔性电路板135穿设旋钮部12的内部并延伸至旋钮部12的外部。柔性电路板135与旋钮部12隔开。在本实施方式中，柔性电路板135能够弯折。
为了提高旋钮10整体外观的美观度，并防止错误对准，本实施方式的显示部131的顶面与旋钮壳121的顶面平齐。
其中，旋钮壳121围绕显示部131。安装部132位于旋钮部12内。转动部1231围绕安装部132。在旋钮10应用于家用电器100时，用户可旋转旋钮部12来对家用电器100的参数进行调节，并且在旋转旋钮壳121时，显示部131能够相对旋钮部12静止，这样旋钮10可通过显示部131清晰地向用户显示相应的家用电器100的参数，以便用户更直观的操作，提高了用户体验。其中，可通过旋钮10实现对家用电器100的功能、时间或功率的调节，这可根据具体情况进行设置。例如，在家用电器100为微波炉时，旋钮10可用于微波炉的烹饪功能的调节。
另外，显示组件13不容易受旋钮部12的干扰，并且柔性电路板135的设置能够提高在旋钮10上安装显示组件13的可靠性，并能够充分利用旋钮10内部的设置空间，继而利于旋钮10的小型化设计。
下面以图8至图10为例对旋钮10的调节方式进行说明。用户可通过旋转旋钮壳121进行相应选择和调节(例如温度、湿度、时间或功率等)，并且用户可通过按压或点击显示部131进行确认。例如在图8至图9所示的例子中，A图标代表功能选项(例如加热、烘干、解冻或消毒等功能)，B图标代表时间选项，C图标代表功率选项，D图标代表启动选项。用户可先通过旋转旋钮壳121(例如如图8箭头所示顺时针旋转旋钮壳121)以切换显示在显示部131的A图标，并通过点击或按压显示部131(如图9所示)以选定对应的功能选项，这时旋钮10将自动跳转到下一个选项(B图标所对应的时间选项，图8所对应的30秒)。这时用户可继续旋转旋钮壳121(例如如图8箭头所示顺时针旋转旋钮壳121)，以将时间由图8所示的30秒增加至图9所示的35秒，并能够通过点击或按压显示部131(如图9所示)以选定对应的时间(35秒)，这时旋钮10将继续自动跳转到下一个选项(C图标所对应的功率选项，图10所显示的900w)。这时用户可继续旋转旋钮壳121(例如如图9箭头所示顺时针旋转旋钮壳121)，以增大功率或减小功率，并能够通过点击或按压显示部131(如图9所示)以选定对应的功率，这时旋钮10将继续自动跳转到下一个选项(D图标所对应的启动选项)。这时用户可通点击或按压显示部131以启动上述所选定的程序。当然，可以理解，用户通过旋钮10的调节方式并不限于上述方式，可根据具体情况进行相应设置。
下面对本实施方式的旋钮部12的结构作进一步说明。
请结合图11及图12，显示部131包括显示屏1311和透光的盖板1312。盖板1312盖设显示屏1311。显示屏1311至少部分地位于旋钮部12内。盖板1312的顶面与旋钮壳121的顶面平齐。在图12所示的例子中，显示屏1311的外表面形成有粘性层13110。粘性层13110用于粘结盖板1312。
其中，显示屏1311可采用发光二极管(LED)显示屏、有机发光二极管(OLED)显示屏、薄膜晶体管(TFT)显示屏或液晶(LCD)显示屏等。盖板1312可采用玻璃材料制成，玻璃材料例如为有机玻璃材料。
请结合图11及图27，安装部132开设有第二安装槽1320。显示部131至少部分地位于第二安装槽1320。安装部132开设有与第二安装槽1320间隔的过道1321(见图27)。柔性电路板135穿设过道1321。在图27所示的例子中，过道1321呈弯折状。过道1321的形状与柔性电路板135的形状相匹配。
请结合图12及图22至图24，安装部132形成有收容腔1322(见图12)。安装部132的底部具有与收容腔1322连通的第二开口1323。收容腔1322连通过道1321及第二开口1323。柔性电路板135依次穿设过道1321及收容腔1322及第二开口1323，并穿出安装部132。柔性电路板135的部分收容于收容腔1322。这样安装部132能够将柔性电路板135与旋钮部12充分隔开。
请结合图16及图19及图28，第一电路板14开设有通孔141。收容腔1322连通过道1321及通孔141。柔性电路板135从通孔141穿过并伸出第一电路板14。伸出第一电路板14的柔性电路板135与控制面板40电性连接。可以理解，通孔141的尺寸可根据具体情况进行设置。较佳地，请结合图19，通孔141的宽度D范围在0.1-10mm，过道1321的入口13211的长度L范围在1-40mm。例如宽度D可为0.1mm，而长度L可为1mm，或者宽度D可为1mm，而长度L可为10mm，或者宽度D可为10mm，而长度L可为40mm。

在图27所示的例子中，安装壳133包括相背的顶面1331及底面1332。顶面1331开设有第二安装槽1320。第二安装槽1320的侧壁开设有槽口13201。过道1321贯穿顶面1331及底面1332。槽口13201连通过道1321及第二安装槽1320。柔性电路板135能够由槽口13201弯折地伸入过道1321，并穿设过道1321。其中，槽口13201呈矩形状。过道1321的尺寸可根据具体情况进行设置。
请结合图11、图13及图14，安装壳133能够相对于定位件134上下移动。开关15包括抵接安装壳133的弹性触件151。开关15被配置为在安装壳133向下移动时，触发弹性触件151。即，安装壳133向下移动以按压弹性触件151。需要说明的是，在安装壳133未被按压时，安装壳体133可与弹性触件151不接触。较佳地，在安装壳133未被按压时，安装壳体133与弹性触件151接触。
在本实施方式中，请结合图14，在盖板1312受到按压时，显示部131受按压而随着安装壳133相对于定位件134向下移动以按压弹性触件151。在盖板1312不受按压时，压缩状的弹性触件15不受压后恢复并驱动安装壳133相对于定位件134向上移动，并使显示部131恢复至原来位置(如图13所示)。这样能够通过开关15对功能进行选定。其中，开关15例如为轻触开关。
为了提高弹性触件15抵接安装壳133的稳定性，安装壳133的中部形成有向下延伸的导向臂1333(见图13)。弹性触件15抵接导向臂1333。向下移动的安装壳133通过导向臂1333按压弹性触件15，压缩后的弹性触件15不受压后恢复并驱动导向臂1333向上移动。
请结合图13，安装壳133包括壳本体1334和自壳本体1334向下延伸的连接端1335。壳本体1334开设有第二安装槽1320。显示屏1311至少部分地设置在第二安装槽1320。连接端1335与定位件134连接。定位件134用于通过连接端1335导向安装壳133的移动。其中，连接端1335围绕导向臂1333。在本实施方式中，显示屏1311整体容置于第二安装槽1320。过道1321贯穿壳本体1334。
请结合图13，连接端1335包括向下延伸的安装臂1336。安装臂1336开设有第一导向件1337。定位件134呈环形。定位件134的内侧壁设有第二导向件1341。第一导向件1337与第四导向件1338配合连接以导向安装壳133的移动。在本实施方式中，第一导向件1337为槽结构。第二导向件1341至少部分地位于第一导向件1337内。第一导向件1337能够相对于第二导向件1341上下移动。即第二导向件1341的位置不动，作为导向槽的第一导向件1337能够上下移动。
请结合图13及图14，导向臂1333基本圆柱体状。导向臂1333的中心线与旋钮部12的中心轴线Y重叠。在显示部131不受按压时，显示部131的顶面与旋钮壳121的顶面平齐，第一导向件1337的底部抵持第二导向件1341(如图13所示)。在显示部131受按压时，显示部131整体相对于旋钮壳121向下移动，安装壳133一并向下移动并通过导向臂1333按压弹性触件15以触发开关15。
可以理解，为了提高第一导向件1337相对于第二导向件1341上下移动的稳定性，安装臂1336的数目为多个。多个安装臂1336沿连接端1335的周向间隔分布。多个安 装臂1336围绕导向臂1333。每个安装臂1336开设有第一导向件1337。第二导向件1341的数目与安装臂1336的数目对应，多个第二导向件1341沿定位件134的周向间隔分布。多个第二导向件1341分别至少部分地位于第一导向件1337内。第二导向件1341的数目可根据具体情况进行设置，例如，第二导向件1341可以为3个、4个、5个或者6个等。另外，第一导向件1337的长度G可根据具体情况进行设置，例如可将第一导向件1337的长度G设置在1-15mm范围。
可以理解，安装臂1336可以具有柔性，即安装臂1336可以采用柔性材料制成。这样在第一导向件1337相对于第二导向件1341上下移动时，安装臂1336能够抵持第二导向件1341而实现弯曲。
为了提高安装壳133相对于定位件134移动的稳定性，定位件134的内侧壁开设有第三导向件1342。连接端1335的外侧壁设有第四导向件1338。第四导向件1338与第三导向件1342配合连接以导向连接端1335安装至定位件134内。较佳地，第三导向件1342为槽结构，第四导向件1338与作为导向槽的第三导向件1342配合连接以使连接端1335至少部分地位于定位件134内。
可以理解，第三导向件1342的数目为多个。每个第三导向件1342向下延伸。多个第三导向件1342沿安装壳133的周向间隔分布。第四导向件1338的数目与第三导向件1342的数目对应。多个第四导向件1338沿定位件134的周向间隔分布。需要说明的是，第三导向件1342的数目可根据具体情况进行设置，例如第三导向件1342的数目可为3个、4个、5个或者6个等。
请结合图16及图18及图22，定位件134的外侧壁形成有第五导向件1343。基座11的内侧壁形成有导向槽111。第五导向件1343与导向槽111配合连接以将定位件134安装于基座11。本实施方式的定位件134位置是固定的。在图12所示的例子中，第二紧固件16穿设第一电路板14并固定于定位件134内。
为了进一步提高旋钮10的交互，在图5及图7所示的例子中，壳件30上设置有第一按钮31和第二按钮32。壳件30的背面设置有第二电路板33。第一按钮31和第二按钮32均与第二电路板33电性连接。第二电路板33与控制面板40电性连接。第一按钮31能够用于暂停显示部131或清除显示部131所显示的信息，第二按钮32能够用于启动或暂停用户操作旋钮10所选的对应功能。例如用户通过旋钮10选定了加热功能，并已经通过点击或按压显示部131启动了加热功能，这时用户可通过操作第二按钮32暂定加热。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它 们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
上文的公开提供了许多不同的实施方式或例子用来实现本发明的不同结构。为了简化本发明的公开，上文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本发明。此外，本发明可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本发明提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
在本说明书的描述中，参考术语“一个实施方式”、“一些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
