下面参考附图描述根据本发明实施例的用于烹饪器具的防溢检测装置10。
如图1-图8所示，根据本发明实施例的用于烹饪器具的防溢检测装置10包括防溢检测板100、防溢检测探头200和检测芯片。
防溢检测板100上设有气泡过孔110，防溢检测板100为导电材料件且下表面构成第一检测面。防溢检测探头200与防溢检测板100之间具有适于气泡填充的间隙，防溢检测探头200的下表面和/或侧表面构成第二检测面，防溢检测探头200的检测值随所述第一检测面和所述第二检测面接触介质的变化而变化。所述检测芯片与防溢检测探头200相连，所述检测芯片通过检测防溢检测探头200的检测值变化量以生成检测信号。
下面参考附图描述根据本发明实施例的用于烹饪器具的防溢检测装置10的工作过程。
烹饪器具停止加热时，防溢检测探头200和防溢检测板100处于断开状态。烹饪器具开始加热时，烹饪器具内逐渐产生气泡，气泡通过气泡过孔110穿过防溢检测板100，之后气泡填充在所述间隙内，防溢检测板100和防溢检测探头200通过气泡实现连接，防溢 检测探头200的检测值随防溢检测探头200本身接触介质的变化以及防溢检测板100的下表面接触介质的变化而变化，所述检测芯片通过检测防溢检测探头200的检测值变化量以生成检测信号，并控制烹饪器具1的工作状态，防止气泡溢出。
根据本发明实施例的用于烹饪器具的防溢检测装置10，通过使防溢检测探头200和防溢检测板100之间具有适于气泡填充的间隙，可以在气泡通过气泡过孔110后填充在所述间隙内，以利用气泡连接防溢检测探头200和防溢检测板100，利用防溢检测探头200和防溢检测板100共同对气泡进行检测。
这样在气泡未发生溢出时，防溢检测探头200仅通过自身的所述第二检测面进行检测，检测面积较小，可以防止由于环境影响而导致防溢检测探头200发生误判，从而可以提高防溢检测装置10检测的准确性和可靠性。
在气泡发生溢出时，防溢检测探头200和防溢检测板100通过气泡相连，防溢检测探头200通过所述第一检测面和所述第二检测面共同对气泡进行检测，从而增大用于检测气泡的整体面积，放大防溢检测探头200产生的检测值，使防溢检测装置10检测更加灵敏，避免气泡发生溢出却无法检测到的情况发生。
也就是说，防溢检测装置10相比相关技术中的检测装置，不仅可以保证检测及时准确，而且可以提高检测的准确性和可靠性，防止误判。
因此，根据本发明实施例的用于烹饪器具的防溢检测装置10具有检测及时、灵敏度高、准确性好等优点。
下面参考附图描述根据本发明具体实施例的用于烹饪器具的防溢检测装置10。
在本发明的一些具体实施例中，如图1-图4所示，根据本发明实施例的用于烹饪器具的防溢检测装置10包括防溢检测板100、防溢检测探头200和检测芯片。
防溢检测探头200与气泡过孔110在上下方向上相对，防溢检测探头200的下表面与防溢检测板100的上表面间隔开以构成所述间隙。这样可以使气泡通过气泡过孔110后能够直接接触防溢检测探头200，从而进一步提高用于烹饪器具的防溢检测装置10检测的及时性和灵敏度。
本领域的技术人员可以理解的是，防溢检测探头200也可以配合在气泡过孔110内，且防溢检测探头200的外周面和气泡过孔110的内周面间隔开以构成所述间隙。
在本发明的一些具体实施例中，与防溢检测探头200的下表面的面积相同的圆的直径以及与气泡过孔110的面积相同的圆的直径的差小于与防溢检测探头200的下表面的的面积相同的圆的直径以及与气泡过孔110的面积相同的圆的直径中较大的一个。
具体地，如图3和图4所示，防溢检测探头200的下表面为圆形，气泡过孔110为圆形，防溢检测探头200的下表面的直径a与气泡过孔110的直径c的差小于防溢检测探头200的下表面的直径与气泡过孔110的直径中较大的一个。这样可以在气泡能够顺利通过所述间隙的情况下便于气泡填充所述间隙，从而进一步提高检测的准确性。
有利地，与防溢检测探头200的下表面的面积相同的圆的直径大于防溢检测探头200的下表面与防溢检测板100的上表面之间的距离的三分之一。
更为具体地，如图3和图4所示，防溢检测探头200的下表面为圆形，防溢检测探头200的下表面的直径大于防溢检测探头200的下表面与防溢检测板100的上表面之间的距离的三分之一。这样可以保证防溢检测探头200的下表面具有足够的面积，保证气泡与防溢检测探头200的下表面的接触面积，从而进一步提高防溢检测装置10的检测效果。
具体而言，防溢检测探头200的半径小于气泡过孔110的半径，防溢检测探头200的外表面与防溢检测板100的上表面之间的最小距离不大于5毫米。
防溢检测探头200的半径小于气泡过孔110的半径，防溢检测探头200的下表面为圆形，气泡过孔110为圆形，防溢检测探头200的半径和气泡过孔110的半径的差不大于5毫米。这样可以使防溢检测探头200和气泡过孔110具有合适的尺寸。
本领域的技术人员可以理解的是，防溢检测探头200的下表面和气泡过孔110也可以不为圆形。
图1和图3示出了根据本发明一个具体实施例的用于烹饪器具的防溢检测装置10。如图1和图3所示，所述检测芯片为电压检测芯片，防溢检测探头200包括导电体210，导电体210的下表面和/或侧表面构成所述第二检测面，导电体210的电阻值随所述第一检测面和所述第二检测面接触介质的变化而变化，导电体210与所述电压检测芯片连通以使所述电压检测芯片根据所述导电体的电压值变化量检测所述导电体的电阻值变化量以生成检测信号。这样可以通过检测防溢检测探头200的电压反映防溢检测探头200的电阻变化情况以反映防溢检测探头200与气泡等介质接触的情况，从而实现气泡溢出的检测。
具体地，如图1和图3所示，导电体210包括底壁211和周壁212。周壁212沿底壁211的周向延伸，底壁211和周壁212中的至少一个的外表面构成所述第二检测面。这样可以便于防溢检测探头200的形成。
图2和图4示出了根据本发明另一个具体实施例的用于烹饪器具的防溢检测装置10。如图2和图4所示，防溢检测探头200包括导电体210和绝缘体220。导电体210与所述检测芯片相连。绝缘体220至少包覆导电体210的侧表面和/或下表面，绝缘体220的侧表 面和/或下表面构成所述第二检测面，导电体210的电容值随所述第一检测面和所述第二检测面接触介质的变化而变化，所述检测芯片为电容检测芯片且所述电容检测芯片通过检测导电体210的电容值变化量以生成检测信号。这样可以通过检测防溢检测探头200的电容反映防溢检测探头200与气泡等介质接触的情况，从而实现气泡溢出的检测。
在本发明的一些具体实施例中，与导电体210的下表面的面积相同的圆的直径以及与气泡过孔110的面积相同的圆的直径的差小于与导电体210的下表面的的面积相同的圆的直径以及与气泡过孔110的面积相同的圆的直径中较大的一个。
具体地，如图3和图4所示，导电体210的下表面为圆形，气泡过孔110为圆形，防导电体210的下表面的直径a与气泡过孔110的直径c的差小于导电体210的下表面的直径与气泡过孔110的直径中较大的一个。这样可以在气泡能够顺利通过所述间隙的情况下便于气泡填充所述间隙，从而进一步提高检测的准确性。
有利地，与导电体210的下表面的面积相同的圆的直径大于导电体210的下表面与防溢检测板100的上表面之间的距离的三分之一。
更为具体地，如图3和图4所示，导电体210的下表面为圆形，导电体210的下表面的直径大于导电体210的下表面与防溢检测板100的上表面之间的距离的三分之一。这样可以保证导电体210的下表面具有足够的面积，保证气泡与防溢检测探头200的下表面的接触面积，从而进一步提高防溢检测装置10的检测效果。
本领域的技术人员可以理解的是，导电体210的下表面和气泡过孔110也可以不为圆形。
可选地，绝缘体220可以包括底壁和沿所述底壁周向设置的周壁，所述底壁和所述周壁中的至少一个构成所述第二检测面。
图1-图4示出了根据本发明一些具体示例的用于烹饪器具的防溢检测装置10。如图1-图4所示，防溢检测探头200和防溢检测板100设在烹饪器具1的锅盖上，所述锅盖关闭烹饪器具1的锅身20时，防溢检测板100与锅身20密封连接。防溢检测板100的外周沿可以设有用于密封防溢检测板100和锅身20之间缝隙的密封圈。这样可以保证气泡均通过气泡过孔110，从而进一步提高防溢检测装置10的可靠性。
有利地，防溢检测板100可拆卸地设在烹饪器具1的锅盖上。这样可以便于防溢检测板100和所述锅盖的清理。
可选地，气泡过孔110为多个且防溢检测探头200与多个气泡过孔110中的一个在上下方向上相对。这样可以使气泡能够通过多个气泡过孔110穿过防溢检测板100。
下面参考附图描述根据本发明另一个具体实施例的用于烹饪器具的防溢检测装置10。
如图5-图8所示，根据本发明实施例的用于烹饪器具的防溢检测装置10包括防溢检测板100、防溢检测探头200和检测芯片。
防溢检测板100上设有气泡过孔110，防溢检测板100为导电材料件且下表面构成第一检测面。防溢检测探头200配合在气泡过孔110内且防溢检测探头200与防溢检测板100之间具有适于气泡填充的间隙，具体地，防溢检测探头200的外周面与气泡过孔110的内周面间隔开以构成所述间隙。防溢检测探头200的下表面和/或侧表面构成第二检测面，防溢检测探头200的检测值随所述第一检测面和所述第二检测面接触介质的变化而变化。所述检测芯片与防溢检测探头200相连，所述检测芯片通过检测防溢检测探头200的检测值变化量以生成检测信号。

可选地，防溢检测探头200的下表面的面积与所述第一检测面的面积之和为50-1250平方毫米。这样可以在保证检测面积足够的情况下降低成本。
具体地，如图7和图8所示，气泡过孔110的内周面与防溢检测探头200的外周面之间的距离d不低于2毫米且不高于20毫米。这样可以在保证气泡顺利穿过所述间隙的情况下便于气泡连接防溢检测探头200和防溢检测板100，从而提高防溢检测装置10检测的可靠性。
更为具体地，如图7和图8所示，防溢检测探头200的下表面低于防溢检测板100的下表面。换言之，防溢检测探头200的下表面与防溢检测板100的下表面之间的距离b大于0。这样可以使气泡先接触到防溢检测探头200再接触到防溢检测板100，从而进一步便于对气泡的检测。
