Description

定时组件及电烤箱
相关申请
本发明申请要求2016年05月10日申请的，申请号为201620421870.0，名称为“定时组件及电烤箱”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本实用新型涉及定时器应用技术领域，特别是涉及一种定时组件和应用该定时组件的电烤箱。
背景技术
一般设备上所用的定时器都是沿着第一方向(比如顺时针方向)旋转旋钮，对该定时器进行时间设置，设置完成后，设备开始工作，同时定时器的旋钮沿着第二方向(一般为逆时针方向)自动回转，当设备工作时间达到定时器所设定的时间以后，设备与定时器一同停止，旋钮也会自动回到关的位置。
但是有一些定时器因为能够接受的最大设定时间比较短，而设备需要工作的时间比较长，此时就需要定时器具有常通功能，在常通功能下设备一直保持工作状态，在常通状态下定时器也一直保持工作状态。在这种定时器结构中，当设定的工作时间超过了设备实际需要工作的时间，用户就需要手动让定时器归零关闭定时器，从而关闭设备，定时器从工作状态到归零状态的旋转方向为第二方向，同时选择常通状态的方向也为第二方向，那么用户就有可能将定时器旋到常通状态，这种情况下，有可能用户以为关掉设备了但是设备却一直在工作状态，会造成安全隐患。

具体实施方式
下面结合附图和实施例对本实用新型的具体实施方式作进一步描述，以下实施例仅用于更加清楚地说明本实用新型的技术方案，而不能以此来限制本实用新型的保护范围。
参考图1和图2，本实施例的定时组件100，包括安装面板120，旋钮组件110，旋钮组 件110包括旋钮部112和旋钮轴114，其中，旋钮部112位于安装面板120的一侧，且旋钮部112能够相对安装面板120旋转，此处旋钮部112不仅可以沿着第一方向(通常为顺时针方向)旋转，也可以沿着第二方向(通常为逆时针方向)旋转。旋钮轴114与旋钮部112连接，且能够随旋钮部112旋转，此处旋钮轴114不仅可以沿着第一方向(通常为顺时针方向)旋转，也可以沿着第二方向(通常为逆时针方向)旋转。该旋钮部112具有两个状态，分别为第一状态和第二状态。
还包括定时器130，该定时器130可以是一种机械定时结构，该定时器130包括本体132和第一连接轴134，其中本体132位于安装面板120的另一侧，且与安装面板120固定连接，此处本体132可以通过螺栓或者螺钉与安装面板120连接；第一连接轴134设置在该本体132上，且该第一连接轴134与旋钮部112固定连接。
还包括限位件140，该限位件140与安装面板120固定连接，且该限位件140与旋钮部112配合，此处配合可以是指至少部分旋钮部112与该限位件140配合，使得处于第一状态的旋钮部112不能够自由旋转，即当处于第一状态的旋钮部112旋转时，限位件140能够限制旋钮部112在预设范围内旋转，处于第二状态的旋钮部112旋转时，旋钮部112能够避让该限位件140，本实施例采用的限位件140可以为挡片，当然其他满足同样功能的限位件140也可以，此处需要说明的是，旋钮部112处于第一状态时，该定时组件100为选择定时模式，旋钮部112处于第二状态时，该定时组件100为选择常通模式，此处，定时模式是指该定时组件100处于预设时间模式，即该定时组件100能够获取用户预设的定时时间，该预设的定时时间与旋钮部112在预设范围内旋转相对应，常通模式是指该定时组件100一直处于工作状态。
在使用本实施例定时组件100时，在旋钮部112处于第一状态下，此时该定时组件100处于定时模式，此时通过沿着第一方向(通常为顺时针方向)旋转旋钮部112，预先设定该定时器130的定时时间，此时定时器130便开始工作，当达到预设时间以后，该定时器130便可以自动关闭；另外，当该定时器130出现非人为性故障时，比如到了预设时间以后该定时器130并未停止，该定时组件100上的挡片，能够阻止该定时器130跳转到常通模式，使得机器一直在工作，防止产生安全隐患；另外，用户可能对该定时器130预设的时间过长，超出了实际需要的时间，比如原本需要30分钟但是用户设置了45分钟或者以上的时间，此时用户可能需要主动对该定时器130进行归零操作，需要沿着第二方向(通常为逆时针方向)旋转该旋钮部112，由于定时器130从工作状态到关的方向和选择常通方向一致，因此有可 能会出现用户以为关掉了该定时器130，但是定时器130却一直处于工作状态的情况，造成安全隐患，此时设置的该挡片能够防止上述两种情况事件发生，安全性大大提高；当需要选择常通模式时，通过改变旋钮部112，使得旋钮部112处于第二状态，此时，处于第二状态的旋钮部112旋转时能够避让该挡片，方便用户选择常通模式的定时器130，本实施例结构简单，且能够防止产生安全隐患。
继续参考图2和图3，图2为图1中所示定时组件的旋钮组件结构示意图，图3为图2中所示定时组件的旋钮组件装配示意图。如图2和图3所示，上述旋钮组件110还可以包括弹性件116，此时，旋钮轴114可以通过该弹性件116与旋钮部112弹性连接，此处该弹性件116可以是弹簧，当然，其他具有同样功能的能够产生弹性的部件也可以，为了固定该弹簧，该旋钮组件110还可以包括紧固件118，该紧固件118与弹簧连接，使得该弹簧可以固定于旋钮部112上，上述紧固件118可以是螺钉，其他满足同样功能的紧固件118也可以，此处采用弹簧和螺钉可以使得该定时组件100结构更加简单紧凑。
旋钮轴114进一步的可以包括卡位部114a和第二连接轴114b，该第二连接轴114b与卡位部114a固定连接，卡位部114a通过弹簧与旋钮部112弹性连接。
旋钮部112进一步的可以包括连接柱112a和桶状部112b，该连接柱112a可以为圆柱状，固定设置在桶状部112b上，连接柱112a可以和桶状部112b一起旋转，相应卡位部114a与连接柱112a对应位置上开设有与连接柱112a适配的通孔，此时，弹簧贯穿卡位部上的通孔，与连接柱112a弹性连接，螺钉将该弹簧固定到连接柱112a上。
上述桶状部112b上进一步的开设有至少一个卡位件112c，本实施例优选的可以开设四个卡位件112c，沿着桶状部112b的周向均匀设置，当然其他数目的卡位件112c也可以，本实施例并不限制卡位件112c沿桶状部112b周向均匀设置，其只要满足卡位功能，以及确保处于第一状态的旋钮部112在预设范围内旋转即可，该卡位件112c与卡位部114a卡接，同时，该卡位件112c与挡片配合，当处于第一状态的旋钮部112旋转时，挡片可以限制该卡位件112c在预设范围内旋转，本实施例所指的预设范围即是指该定时组件100处于定时模式时，旋转旋钮部112以期获得对应机器所需要的定时时间，处于第二状态的旋钮部112旋转时，该卡位件112c能够避让挡片。
为了更好地与上述卡位件112c卡接，可以在卡位部114a上开设有至少一个卡位槽114c，该卡位槽114c与卡位件112c相适配，卡位件112c卡入卡位槽114c内，开设的卡位槽114c数目以及沿卡位部114a周向的距离设置与上述卡位件112c相对应，本实施例的卡位槽114c 数目并不仅仅限于此，其数目以及沿卡位部114a的设置只要与卡位件112c相对应即可，本实施例中通过卡位件112c与卡位槽114c卡接，可以周向固定该旋钮轴114，使得该旋钮轴114与旋钮部112处于一个整体，其只能够随旋钮部112一起旋转，结构简单。
本实施例中，旋钮部112处于第一状态时，此时弹簧处于非压缩状态；旋钮部112处于第二状态时，弹簧处于压缩状态，更为具体地，当用户需要改变旋钮部112的状态，期望该定时组件100处于常通模式时，由于旋钮部112与旋钮轴114之间通过弹簧弹性连接，另外第二连接轴114b与第一连接轴134连接，将该旋钮部112往上拉时，此时弹簧处于压缩状态，该旋钮部112往上运动，此时，设置在其中的卡位件112c可以避开挡片，旋钮部112可以正常旋转到常通模式，本实施例结构简单，且方便切换定时模式，避免安全隐患的发生。
在组装该旋钮组件110时，如图3所示，第一步：参考图中A所示，先行将旋钮轴114组装到旋钮部112上，此时卡位件112c与卡位槽114c卡接，周向定位该旋钮轴114，另外卡位部114a上开设的通孔与连接柱112a对应；第二步：参考图中B所示，将弹簧组装到卡位部114a上的通孔中；第三步：参考图中C所示，组装螺钉，将该螺钉组装到弹簧上，固定该弹簧到连接柱112a上。结构简单，装配方便。
继续参考图4，为图1中所示定时组件100的安装面板120的局部示意图，如图所示，安装面板120上设有限位件140，本实施例优选的限位件140包括挡片，该挡片设于安装面板120上，且凸出于安装面板120，当然也可以使用其他结构形式的能够满足同样功能的限位件140。
继续参考图5，为图1中所示一实施例中定时组件100处于第一状态时的剖视图，图5中，当定时组件100达到预设时间以后，挡片便会阻止卡位件114a通过该挡片，进一步阻止旋钮部112继续旋转，从而使得该定时器130能够立马停止计时，相应机器便会停止工作。
继续参考图6，为图1中一实施例中定时组件100处于第二状态时的剖视图，如图6所示，当需要使用第二状态的定时组件100时，只需要将旋钮部112往上拉，从而压缩弹簧，此时由于旋钮部112往上运动，设置在其中的卡位件114a便可以避开该挡片，进一步旋钮部112可以正常旋转。
继续参考图7，为图1中一实施例中定时组件100工作方式情景图，正如图7中所示，定时组件100有两种状态，定时模式，顺时针旋转，预设定时器130的定时时间，当实际工作时间比预设时间少时，此时需要用户手动归零，其旋转方向为逆时针方向，而选择常通模式的旋转方向与归零方向一样，都为逆时针方向，两者方向一致，容易产生安全隐患，本申 请文件设置的挡片以及旋钮部112，切换旋钮部112不同的状态，能够方便地选择这两种模式，同时也避免了产生上述的安全隐患。
下面将继续描述本实用新型的工作原理：
当用户在定时模式使用该定时组件100时，手动从工作状态关闭定时器130时，只要定时器130达到关的位置，挡片阻挡旋钮部112继续往常通模式方向转动，从而防止定时器130达到常通状态。当用户需要在常通模式使用该定时组件100时，用户需要将旋钮部112往上拉，从而压缩弹簧，卡位件114a避开挡片140，如图6所示，从而旋钮部112可以从定时模式正常旋转到常通模式，不影响用户使用常通模式的定时组件100。
另外本装置还可以防止定时器130在出现故障时跳到常通模式导致机器一直运作，避免因此带来的安全隐患。
继续参考图8，为一实施例中电烤箱的结构示意图，涉及本申请的第二方面，一种电烤箱，包括电烤箱本体200和上述任一项实施例的定时组件100，该定时组件100设于电烤箱本体200上。可以一并参考图2，当需要在定时模式使用该电烤箱时，只需要沿着顺时针方向旋转该定时组件100中的旋钮部112，该旋钮部112旋转到需要的刻度时，释放旋钮部112，则定时器130内的触点就会接通，此时电烤箱开始工作；当需要在常通模式使用该电烤箱时，可以改变定时组件100中的旋钮部112，使其处于第二状态，此时可以避让挡片。更为具体的定时组件100结构可以参考本申请第一方面所描述的定时组件100，在此不作赘述。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
