具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图38描述根据本发明实施例的锅盖组件40和烹饪器具1。这里的烹饪器具1可以是压力锅。
如图1-图38所示，根据本发明实施例的锅盖组件40包括：锅盖本体100和锅盖锁紧组件。
所述锅盖锁紧组件用于对关闭状态的锅盖本体100进行锁紧，所述锅盖锁紧组件安装在锅盖本体100上且包括导轨210、第一卡扣31和第二卡扣32。导轨210设在锅盖本体100上且导轨210的两端与锅盖本体100相连，导轨210至少中部与锅盖本体100之间具有避让间隙。第一卡扣31和第二卡扣32在锅盖本体100的周向上相对设置，第一卡扣31和第二卡扣32可彼此相互靠近或远离地设在导轨210上。
根据本发明实施例的锅盖组件40，通过设置安装在锅盖本体100上的所 述锅盖锁紧组件，可以对关闭状态的锅盖本体100进行锁紧，这样不仅可以在烹饪时保证烹饪器具1的烹饪效果，而且可以保证锅盖本体100关闭状态的可靠锁紧，使烹饪器具1能够可靠工作。
并且，由于导轨210的两端与锅盖本体100相连，导轨210至少中部与锅盖本体100之间具有避让间隙。这样可以利用所述避让间隙避让由于压力而变形的锅盖本体100，避免锅盖本体100变形后与导轨210接触，这样可以减少锅盖本体100的变形对所述锅盖锁紧组件的影响，避免锅盖本体100顶部受压变形后与导轨210产生干涉，影响锅盖本体100的打开和关闭性能。
此外，由于导轨210与锅盖本体100之间具有所述避让间隙，这样可以避免锅盖本体100变形导致导轨210变形，保证第一卡扣31和第二卡扣32在导轨210上顺畅滑动，提高所述锅盖锁紧组件的工作性能。
同时，导轨210与锅盖本体100之间具有所述避让间隙，保证所述锅盖锁紧组件的正常移动，使第一卡扣31和第二卡扣32滑动顺畅，保证第一卡扣31和第二卡扣32实现对锅盖组件40的锁紧或打开，避免锅盖组件40无法打开或关闭的发生，便于用户的使用，提高用户的使用舒适性。
进一步地，由于锅盖本体100的中部更易发生变形，导致锅盖本体100中部变形量较大，在导轨210的中部与锅盖本体100之间设置避让间隙，能够针对锅盖本体100中部变形较大的位置进行避让，为锅盖本体100的变形留出足够的余量，减小锅盖本体100变形所产生的影响，保证锅盖本体100受压变形后不会与所述锅盖锁紧组件产生干涉，即锅盖本体100在受压向上变形后，其不会向上不易与导轨210接触，从而不会不易将锅内压力传递至导轨210上，确保便于导轨210仍然保持其初始的直线延伸状态，不会不易发生弯曲，从而也就确保了拉杆能够顺延导轨210顺畅的滑动，。或者说，在锅盖本体100受 压变形后，即使锅盖本体100与导轨210接触，由于锅内压力必须首先使锅盖本体100变形，即使锅盖本体在形变后与导轨接触，其传递至导轨210上的压力也不足以能够使导轨210发生较大形变。
因此，根据本发明实施例的锅盖组件40具有可靠性高、使用舒适等优点。
下面参考附图描述根据本发明具体实施例的锅盖组件40。
可选地，导轨210与锅盖本体100之间的最大间隙大于2毫米。这样可以为锅盖本体100的变形留出足够的余量，进一步可以避免锅盖本体100受压变形后对导轨210产生干涉，从而影响锅盖本体100的打开和关闭性能。
具体地，在导轨210的长度方向上，所述避让间隙的宽度由中部至两端逐渐减小。锅盖本体100在受锅内压力时，其边缘通过卡扣与烹饪器具1的内锅或外锅紧固，导致锅盖本体100中部变形量与边缘变形量存在不同，即是说，在受锅内压力时，锅盖本体100中部位置由于形变产生的向上位移大于锅盖本体100边缘产生的向上位移，并且这种位移量的大小是渐变的，针对该问题，本实施方式中将上述间隙设置为相应的渐变构造，在确保能够有足够的空间来避让锅盖本体100形变的同时，降低了锅盖本体100整体的高度。
在本发明的一个具体实施例中，如图7-图10所示，锅盖本体100的上表面设有沉槽110，所述避让间隙由沉槽110的底壁和导轨210的下表面共同限定出。这样便于所述避让间隙的形成，便于降低锅盖本体100变形对导轨210的影响，而且可以便于控制锅盖组件40的整体厚度。
具体地，如图10所示，沉槽110的中部低于沉槽110的两端，导轨210的两端分别连接在沉槽110的两端。这样不仅可以便于所述避让间隙的形成，而且可以便于导轨210的安装。此外，由于锅盖本体100中部较边沿更容易发生变形，设置中部较低的沉槽110可以进一步避免锅盖本体100的变形影响导 轨210。
在本发明的另一个具体实施例中，导轨210的两端均连接在锅盖本体100的周壁上且与锅盖本体100的连接处在锅盖本体100的周向上相对设置。这样同样可以实现导轨210的安装。
可选地，如图9所示，导轨210的两端设有向外且向锅盖本体100倾斜延伸的折弯段211。这样可以增大导轨210与锅盖本体100的接触面积，便于导轨210与锅盖本体100的连接，而且可以便于所述避让间隙的形成，在避免导轨210两端过高的情况下便于增大所述避让间隙的尺寸，便于对锅盖本体100的变形进行缓冲，进一步防止导轨210发生变形。同时由于便于控制导轨210两端的高度，可以避免导轨210对卡扣产生干涉，便于卡扣与锅盖本体100相互扣合。
具体地，锅盖本体100的横截面具有彼此正交的长轴和短轴。具体而言，锅盖本体100大体为椭圆形。这样便于对大块状的长方形食材进行烹饪，便于提高用户的使用体验。
进一步地，导轨210沿所述短轴定向。这样便于提高所述锅盖锁紧组件的结构强度，便于提高所述锅盖锁紧组件的稳定性，而且由于锅盖本体100的短轴方向较长轴方向上更不容易发生变形，可以进一步避免锅盖本体100的变形影响所述卡扣的滑动。
图7-图10示出了根据本发明的锅盖组件40。如图2所示，第一卡扣31包括可滑动地设在导轨210上的第一拉杆221和连接在第一拉杆221上的第一卡扣本体222，第二卡扣32包括可滑动地设在导轨210上的第二拉杆231和连接在第二拉杆231上的第二卡扣本体232。这样可以通过第一拉杆221和第二拉杆231分别驱动第一卡扣本体222和第二卡扣本体232，实现利用第一卡 扣本体222和第二卡扣本体232对锅盖本体100进行锁紧。
具体而言，锅盖组件40还包括开盖把手，所述开盖把手分别与第一拉杆221和第二拉杆231传动连接。
具体地，锅盖本体100上至少设有第一加强筋310和第二加强筋320，第一加强筋310设在所述短轴的中部,且第一加强筋310的延伸方向与所述长轴的延伸方向一致，第二加强筋320邻近所述长轴的两端设置，且第二加强筋320的延伸方向与所述短轴的延伸方向一致。
相比单独设置位于长轴两端的加强筋或单独设置短轴中部的加强筋，这样可以同时加强锅盖本体100的所述短轴的中部和所述长轴两端的强度和刚性，避免锅盖本体100出现受压薄弱点，提高锅盖本体100的强度和刚性。这样在满足承压要求的情况下可以减小锅盖本体100的材料厚度，便于降低锅盖本体100的制造成本，从而减小烹饪器具1的整体成本。
同时，以减小锅盖本体100的材料厚度，便于控制烹饪器具1的高度尺寸，减小烹饪器具1占用的空间，便于使烹饪器具1的外观更美观，而且由于锅盖本体100不需要较大的厚度，可以便于减小锅盖本体100的重量，减小锅盖本体100在打开关闭时的惯性，从而使锅盖本体100连接及定位结构的寿命更长，提高烹饪器具1的可靠性。
此外，以减小锅盖本体100的材料厚度，这样可以减小锅盖本体100的重量，从而减小用户在操作锅盖本体100时的惯性，便于用户对烹饪器具1进行操作，便于提高用户的使用舒适性。
进一步地，由于相关技术中的烹饪器具在承受内部压力时，锅盖的短轴端容易向下折弯变形，锅盖的长轴两端容易上翘变形，导致烹饪器具密封不良、泄压、甚至锁扣脱扣。第一加强筋310设在所述短轴的中部，能够减小锅盖本 体100所述短轴端的变形，提高锅盖本体100的结构强度。同时锅盖本体100的所述长轴较所述短轴更易发生变形，将第二第三加强筋330邻近所述长轴的两端设置，可以减小锅盖本体100所述长轴两端的变形，进一步提高锅盖本体100的结构强度，提高锅盖本体100的稳定性，从而减小锅盖本体100的变形对锅盖组件200的其他零部件产生的影响。
更进一步地，可以便于锅盖本体100上导轨的设置。例如，锅盖本体100上设有长度方向沿长轴定向的导轨210，通过设置第一加强筋310和第二加强筋320，不仅可以使第一加强筋310沿导轨210的方向定向，以对锅盖本体100上导轨210所处的位置进行加强，可以减小锅盖本体100变形对导轨210所产生的影响，保证锅盖本体100不会与导轨210产生干涉，从而不易将锅内压力传递至导轨210上，便于导轨210仍然保持其初始的直线延伸状态，不易发生弯曲，而且可以使第二加强筋320分别邻近导轨210的两端，防止锅盖本体100上位于导轨210两端处产生上翘变形，进一步减小对锅盖本体100变形对导轨210的影响。
可选地，如图12-图15所示，第一加强筋310的长度方向沿所述长轴的方向定向，第二加强筋320的长度方向沿所述短轴的方向定向。这样第一加强筋310和第二加强筋320能够分别加强锅盖本体100所述短轴方向和所述长轴方向上的强度和刚性，使第一加强筋310和第二加强筋320能够在锅盖本体100上覆盖更大的面积，提高锅盖本体100的结构强度，提高锅盖本体100的稳定性，进一步提高锅盖本体100的抗变形能力。
具体地，第一加强筋310和第二加强筋320分别与锅盖本体100一体成型。这样便于简化锅盖本体100的装配工艺，提高烹饪器具1的生产效率。
具体而言，第一加强筋310和第二加强筋320与锅盖本体100上表面的连 接处圆弧过渡。这样不仅可以便于第一加强筋310和第二加强筋320的形成，而且可以便于锅盖本体100的清洗，避免产生清理死角。
可选地，第一加强筋310由形成在锅盖本体100上的沉台或凸台构成，第二加强筋320由形成在锅盖本体100上的沉台或凸台构成。这样可以提高锅盖本体100的强度和刚性，进一步提高锅盖本体100的结构稳定性，而且可以便于加强筋的设置，提高锅盖本体100的生产效率。
根据本发明的另一个实施例，如图12和图15所示，第二加强筋320为多个且沿所述长轴间隔设置。这样可以使第二加强筋320的受力更加均匀，进一步增强锅盖本体100的强度和刚性。
更为具体地，如图12和图15所示，多个第二加强筋320以所述短轴为轴轴对称设置。这样便于提高锅盖本体100整体结构的强度和刚性，避免锅盖本体100受力不均的发生。
根据本发明的另一个实施例，第一加强筋310为多个且沿所述短轴间隔设置。这样可以使第一加强筋310的受力更加均匀，进一步提高锅盖本体100的稳定性和可靠性。
更为具体地，多个第一加强筋310以所述长轴为轴轴对称设置。这样同样可以便于提高锅盖本体100整体结构的强度和刚性，提高锅盖本体100受力的均匀性。
根据本发明的另一个实施例，如图14所示，第一加强筋310和第二加强筋320相连。这样便于第一加强筋310和第二加强筋320的形成，便于简化第一加强筋310和第二加强筋320的成型加工，而且可以便于锅盖本体100的受力通过加强筋进行传递，避免出现应力集中而导致锅盖本体100局部变形过大，使锅盖本体100的受力更加均匀。
具体地，导轨210沿所述长轴定向。这样可以便于增大导轨210的长度，便于对第一卡扣31和第二卡扣32进行导向和定位，防止第一卡扣31和第二卡扣32打开后上下窜动。
可选地，锅盖本体100上设有至少一个第三加强筋330，第三加强筋330邻近所述长轴的两端设置，第三加强筋330的延伸方向与所述短轴的延伸方向一致。
这样可以加强锅盖本体100的所述长轴两端的强度和刚性，避免锅盖本体100出现受压薄弱点，提高锅盖本体100的强度和刚性。这样在满足承压要求的情况下可以减小锅盖本体100的材料厚度，便于降低锅盖本体100的制造成本，从而减小烹饪器具1的整体成本。
同时，以减小锅盖本体100的材料厚度，便于控制烹饪器具1的高度尺寸，减小烹饪器具1占用的空间，便于使烹饪器具1的外观更美观，而且由于锅盖本体100不需要较大的厚度，可以便于减小锅盖本体100的重量，减小锅盖本体100在打开关闭时的惯性，从而使锅盖本体100连接及定位结构的寿命更长，提高烹饪器具1的可靠性。
此外，以减小锅盖本体100的材料厚度，这样可以减小锅盖本体100的重量，从而减小用户在操作锅盖本体100时的惯性，便于用户对烹饪器具1进行操作，便于提高用户的使用舒适性。
进一步地，由于锅盖本体100的长轴上较短轴上更易发生变形，将第三加强筋330邻近长轴的两端设置，可以进一步提高锅盖本体100的结构强度，便于提高锅盖本体100的稳定性，可以进一步减小锅盖本体100的变形，从而减小锅盖本体100的变形对锅盖组件4000的其他零部件产生的影响。
具体地，锅盖本体100的横截面为椭圆形。由于相关技术中椭圆形的锅盖 整体刚性较弱，受锅内压力作用，锅盖的所述长轴两端容易出现上翘变形，锅盖变形后会与设置于锅盖顶部的锅盖锁紧组件产生干涉，影响锅盖锁紧组件的卡扣的正常滑动，同时由于卡扣卡合在所述短轴两端，锅盖本体100的受力更加倾向于向所述长轴两端作用。这样锅盖本体100邻近所述长轴的两端设置第三加强筋330，能够加强椭圆形锅盖本体100的所述长轴两端的强度和刚性，避免锅盖本体100的所述长轴两端出现上翘变形，避免锅盖本体100与设置于锅盖顶部的锅盖锁紧组件产生干涉，提高锅盖本体100的可靠性和稳定性。
可选地，第三加强筋330与锅盖本体100一体成型。这样便于简化锅盖本体100的装配工艺，提高烹饪器具1的生产效率。
具体而言，第三加强筋330与锅盖本体100上表面的连接处圆弧过渡。这样不仅可以便于第三加强筋330的形成，而且可以便于锅盖本体100的清洗，避免产生清理死角。
根据本发明的一个实施例，如图18所示，第三加强筋330由形成在锅盖本体100上的沉台331构成。这样不仅可以在不加大锅盖本体100上表面高度的情况下，增强锅盖本体100的强度和刚性，而且便于控制锅盖本体100的高度尺寸，减小锅盖本体100占用的空间。
根据本发明的另一个实施例，如图19所示，第三加强筋330由形成在锅盖本体100上的凸台332构成。这样同样可以提高锅盖本体100的强度和刚性。
根据本发明的另一个实施例，如图21所示，第三加强筋330为多个且沿所述长轴间隔设置。这样可以使第三加强筋330的受力更加均匀，进一步增强锅盖本体100的强度和刚性。
具体地，如图21所示，多个第三加强筋330以所述短轴为轴轴对称设置。这样便于提高锅盖本体100整体结构的强度和刚性，避免锅盖本体100受力不 均的发生。
可选地，锅盖本体100上设有至少一个第四加强筋340，第四加强筋340邻近所述长轴的中部设置，第四加强筋340的延伸方向与所述短轴的延伸方向一致。
这样可以加强锅盖本体100的所述长轴中部的强度和刚性，避免锅盖本体100出现受压薄弱点，提高锅盖本体100的强度和刚性。这样在满足承压要求的情况下可以减小锅盖本体100的材料厚度，便于降低锅盖本体100的制造成本，从而减小烹饪器具1的整体成本。
同时，以减小锅盖本体100的材料厚度，便于控制烹饪器具1的高度尺寸，减小烹饪器具1占用的空间，便于使烹饪器具1的外观更美观，而且由于锅盖本体100不需要较大的厚度，可以便于减小锅盖本体100的重量，减小锅盖本体100在打开关闭时的惯性，从而使锅盖本体100连接及定位结构的寿命更长，提高烹饪器具1的可靠性。
此外，以减小锅盖本体100的材料厚度，这样可以减小锅盖本体100的重量，从而减小用户在操作锅盖本体100时的惯性，便于用户对烹饪器具1进行操作，便于提高用户的使用舒适性。
进一步地，由于相关技术中的烹饪器具在承受内部压力时，锅盖的中部承受较大压力，锅盖易发生中部上拱、短轴两端下沉的变形，导致烹饪器具密封不良、泄压、甚至锁扣脱扣。通过将第四加强筋340邻近所述长轴的中部设置，可以针对锅盖本体100的中部进行加强，同时由于第四加强筋340的长度方向与所述短轴的延伸方向一致，可以沿所述短轴的延伸方向对锅盖本体100的所述长轴的中部进行加强，将所述长轴中部承受的压力通过第四加强筋340均匀分散至所述短轴上各处，从而可以减小锅盖本体100发生中部上拱、短轴两端 下沉的变形，进一步提高锅盖本体100的结构强度，保证锅盖本体100的形状稳定性，减小锅盖本体100的变形对锅盖组件4000的其他零部件产生的影响，提高锅盖本体100的工作可靠性。
更进一步地，通过设置第四加强筋340，可以便于锅盖本体100上导轨的设置。例如，锅盖本体100上设有长度方向沿短轴定向的导轨210，通过设置第四加强筋340，可以使第四加强筋340沿导轨210的方向定向，以对锅盖本体100上导轨210所处的位置进行加强，可以减小锅盖本体100变形对导轨210所产生的影响，保证锅盖本体100不会与导轨210产生干涉，从而不易将锅内压力传递至导轨210上，便于导轨210仍然保持其初始的直线延伸状态，不易发生弯曲。
可选地，第四加强筋340与锅盖本体100一体成型。这样便于简化锅盖本体100的装配工艺，提高烹饪器具1的生产效率。
具体而言，第四加强筋340与锅盖本体100上表面的连接处圆弧过渡。这样不仅可以便于第四加强筋340的形成，而且可以便于锅盖本体100的清洗，避免产生清理死角。
根据本发明的一个实施例，如图24所示，第四加强筋340由形成在锅盖本体100上的沉台331构成。这样不仅可以在不加大锅盖本体100上表面高度的情况下，增强锅盖本体100的强度和刚性，而且便于控制锅盖本体100的高度尺寸，减小锅盖本体100占用的空间。
根据本发明的另一个实施例，如图25所示，第四加强筋340由形成在锅盖本体100上的凸台332构成。这样同样可以提高锅盖本体100的强度和刚性。
根据本发明的另一个实施例，如图27所示，第四加强筋340为多个且沿所述长轴间隔设置。这样可以使第四加强筋340的受力更加均匀，进一步增强 锅盖本体100的强度和刚性。
具体地，如图27所示，多个第四加强筋340以所述短轴为轴轴对称设置。这样便于提高锅盖本体100整体结构的强度和刚性，避免锅盖本体100受力不均的发生。
可选地，所述锅盖锁紧组件用于对关闭状态的锅盖本体100进行锁紧，所述锅盖锁紧组件安装在锅盖本体100上且包括导轨210和两个卡扣。导轨210设在锅盖本体100上。两个卡扣在锅盖本体100的周向上相对设置，两个卡扣在夹持位置和释放位置之间可彼此相互靠近或远离地设在导轨210上，在所述夹持位置时，两个卡扣夹持锅盖本体100，在所述释放位置时，两个卡扣远离锅盖本体100。面盖500与锅盖本体100之间限定出容纳腔，导轨210设在所述容纳腔内，卡扣至少在所述夹持位置时配合在所述容纳腔内。
相比相关技术中锅盖顶部裸露的方式，面盖500能够对所述锅盖锁紧组件进行遮挡，这样能够实现用户与锅盖组件40的隔离，避免用户误触温度较高的锅盖组件40而发生危险，防止用户被高温的锅盖组件40烫伤，保证用户的使用安全性，提高锅盖组件40的工作可靠性，从而提高烹饪器具1可靠工作。
此外，相比将卡扣完全包覆的面盖，可以减少锅盖组件40使用的材料，简化锅盖组件40的设计和制造过程。这样便于控制锅盖组件40的生产加工，便于降低烹饪器具1设计和制造难度，便于降低烹饪器1具的成本，提高烹饪器具1的生产效率。
进一步地，不仅可以提高烹饪器具1的外观整体性，使1烹饪器具1外形更加整齐美观，而且便于保护锅盖组件40的内部结构，便于提高锅盖组件40的工作性能，从而提高烹饪器具1的稳定性和可靠性。
具体地，如图36所示，面盖500包括面盖盖板510和与面盖盖板510的 外周沿相连的面盖围板520，面盖围板520的下边沿设有卡扣避让槽521，卡扣避让槽521用于避让卡扣。这样可以避免卡扣在滑动的过程中和面盖500发生干涉，便于卡扣的顺畅、灵活滑动，相比相关技术中将卡扣完全包覆的面盖，能够避免预留卡扣在所述夹持位置和所述释放位置之间相互靠近或远离地滑动所需要的空间，便于控制烹饪器具1的尺寸，便于减小烹饪器具1占用的空间，便于使烹饪器具1的外观更美观，便于减小锅盖组件40的重量，减小锅盖组件40在打开关闭时的惯性，提高用户的使用舒适性。
更为具体地，如图37和图38所示，卡扣的下边沿与面盖围板520的下表面平齐。这样便于提高锅盖组件40的外观整体性，便于提高锅盖组件40的外观美观性。
可选地，如图37所示，卡扣位于所述夹持位置时，卡扣的外周面与面盖500的外周面平齐。这样使锅盖组件40的外观平滑，便于在实现防烫功能的前提下实现面盖500结构的最优化。
具体地，如图36所示，每个卡扣包括拉杆和卡扣本体。拉杆可移动地设在导轨210上，面盖围板520上设有用于避让拉杆的拉杆避让槽522，卡扣本体与拉杆的外端相连。这样便于拉杆的设置，便于避免拉杆在滑动的过程中和面盖围板520发生干涉，便于拉杆的可靠滑动。
更为具体地，如图36-图38所示，每个卡扣还包括挡板223，挡板223设在拉杆和卡扣本体的至少一个上且遮挡卡扣本体和拉杆的连接处。这样便于挡板223对卡扣本体和拉杆的连接处进行遮挡，避免用户误触所述高温的连接处而产生安全隐患。
进一步地，如图36所示，拉杆与卡扣本体的上表面相连，拉杆避让槽522形成在卡扣避让槽521的底壁上。这样不仅便于拉杆与卡扣本体能够同步移 动，而且便于拉杆避让槽522的形成。
可选地，如图37所示，卡扣位于所述夹持位置时，挡板223的外周面与面盖围板520的外周面平齐。这样进一步便于锅盖组件40的外观平滑。
可选地，如图36所示，锅盖组件40还包括把手600，面盖500上设有把手过孔530，把手600穿过把手过孔530分别与两个卡扣传动连接。这样便于把手600的设置，便于把手600带动两个卡扣在所述夹持位置和所述释放位置之间切换。
下面描述根据本发明实施例的烹饪器具1。根据本发明实施例的烹饪器具包括根据本发明上述实施例的锅盖组件40。
具体地，所述锅体组件包括外锅10和设在外锅10内的内锅20。外锅10的侧周壁横截面具有彼此正交的长轴m和短轴n。外锅10在长轴m方向上的相对侧壁分别向下内凹形成缺口12。锅盖组件40可拆卸地设在所述锅体组件上。
所述锅盖锁紧组件设在锅盖组件40上且可在所述夹持位置和所述释放位置之间移动。所述锅盖锁紧组件包括在短轴n方向间隔设置的第一卡扣31和第二卡扣32。在所述夹持位置，第一卡扣31和第二卡扣32夹持外锅10以使锅盖组件40扣紧锅体组件。在所述释放位置，第一卡扣31和第二卡扣32松开外锅10以使锅盖组件40脱离锅体组件。
其中，在所述夹持位置，第一卡扣31和第二卡扣32的一端外侧在短轴n方向上的距离为L1，缺口12在短轴n方向上的宽度为L，1≤L1/L≤2。
根据本发明实施例的烹饪器具1，通过在锅体组件上设置所述锅盖锁紧组件，并将所述锅盖锁紧组件与外锅10之间的配合满足上述关系，可以通过所述锅盖锁紧组件与外锅10的扣合，实现锅盖组件40与锅体组件的扣合，并且 可以减小因结构强度不均而造成承力状态出现不稳定的现象，保证所述锅盖锁紧组件与外锅10的扣合强度，从而提高锅体组件与锅盖组件40的连接可靠性。并且，所述锅盖锁紧组件与外锅10的扣合方式适用不规则形状的外锅10与锅盖组件40的扣合，使用范围广。
在一些可选的示例中，锅盖组件40扣合在锅体组件上时，第一卡扣31的一端外侧和第二卡扣32的一端外侧在短轴n方向上的距离L1等于外锅10的缺口12在短轴n方向上的宽度L，由此，所述锅盖锁紧组件可以与外锅10的除了缺口12的顶部外缘卡接，保证锅盖组件40与锅体组件扣合可靠。
在另一些可选的示例中，锅盖组件40扣合在锅体组件上时，第一卡扣31的一端外侧和第二卡扣32的一端外侧在短轴n方向上的距离L1等于外锅10的缺口12在短轴n方向上的宽度L的两倍。
如图3-图6所示，根据本发明一个实施例，外锅10包括：外锅本体11和位于外锅本体11顶部的锅沿。外锅本体11包括底壁和沿底壁的周向围设的侧周壁，侧周壁的横截面具有彼此正交的长轴m和短轴n，即外锅10的横截面形状为非圆形。其中，外锅本体11在长轴m方向上的相对侧壁向下内凹形成缺口12，且在缺口12处的侧壁朝向外锅本体11外一侧延伸。
由此，通过在外锅本体11的位于长轴m处的侧壁上设置向下凹陷的缺口12，可以用来避让内锅20把手21，这样内锅20放置到外锅10内时，把手21可放到缺口12内，不会影响内锅20的放置，保证烹饪器具1的正常使用，便于用户取放内锅20，还可以降低外锅10与内锅20组装后的整体高度。
根据本发明一个实施例，外锅本体11的横截面形状可以形成椭圆形，外锅本体11的侧壁上周缘设有两个沿外锅本体11的轴向向下内凹的缺口12，两个缺口12在椭圆的长轴m方向上相对设置。缺口12的宽度由下至上逐渐增 大，缺口12顶端处的宽度为L。
对应地，内锅20的横截面形状形成与外锅本体11的横截面形状对应的椭圆形，内锅20的外周壁设有两个相对布置的把手21，两个把手21分别与外锅10的两个缺口12位置一一对应。
如图4和图5所示，根据本发明一个实施例，缺口12在短轴n方向上的宽度L可以取40mm到120mm之间的任意值。进一步，缺口12在外锅本体11高度方向上的深度H可以取2mm到30mm之间的任意值。
在一个具体地示例中，外锅本体11上的两个缺口12的宽度L均为70mm，缺口12深度H为15mm。该缺口12的设置，在满足容纳内锅20的把手21的同时，有利于外锅10的成型，且不会削弱外锅10的强度。
当然，缺口12的宽度L的取值并不限于上述的40mm～120mm，深度H的取值也并不限于上述的2～30mm，具体可根据实际需要进行设定。
根据本发明的一个实施例，外锅10顶部开口处的边缘设置有向外延伸的翻边，该翻边在缺口12底边的位置处连续延伸。通过在外锅10上设置翻边，可以增加外锅10侧壁的强度，降低了缺口12对外锅本体强度的影响，避免发生承力状态不稳定现象，并可以更好地与内锅20配合。
如图3和图4所示，在一些示例中，第一卡扣31和第二卡扣32分别形成沿外锅10侧周壁的周向延伸的弧形，从而便于夹持外锅10位于长轴两侧的锅沿。进一步地，第一卡扣31和第二卡扣32关于长轴对称布置，有利于保证所述锅盖锁紧组件与锅体组件的稳定配合，避免发生承力状态不稳定的现象。
在一些具体示例中，第一卡扣31和第二卡扣32中的每一个包括：围板、上夹板和下夹板。
围板沿外锅10的轴向(如图3所示的上下方向)延伸，上夹板和下夹板 分别形成布置在水平面内的弧形板，上夹板连接至围板的上沿，下夹板连接至围板的下沿，上夹板、下夹板和围板共同限定出开口在外锅10的径向上朝向内侧的卡槽，用于容纳外锅10的锅沿。所述L1为所述锅盖锁紧组件锁紧在外锅10上时、第一卡扣31的围板的一端和第二卡扣32的围板的一端在短轴方向上的距离。
在一些示例中，外锅10的底部设有发热盘组件60，内锅20设在外锅10内时，加热盘组件60工作以对内锅20加热。
下面参考图1-图6描述根据本发明实施例的烹饪器具1的锅体组件。
如图1-图6所示，根据本发明实施例的锅体组件包括内锅20和外锅10，内锅20设在外锅10内。
内锅20的外侧壁上设有两个相对布置的把手21，内锅20的把手21的宽度小于外锅本体11的缺口12的宽度L，内锅20的把手21的高度小于外锅本体11的缺口12的高度H，使得两个把手21可以分别放置于外锅本体11对应的缺口12内。通过采用上述外锅10，便于取放内锅20，减少了烫伤事故的发生，使得烹饪器具1的使用更加安全，还可以降低锅体组件的整体高度。
在一些示例中，内锅20的横截面形状可以形成与外锅10的横截面形状对应的椭圆形。两个把手21分别设在内锅20的长轴m所在的方向上。
在一些示例中，锅体组件的内锅20的外侧壁与外锅本体11的内侧壁留有间隙，即内锅20的上端凸出外锅11的锅沿，内锅20的把手21放置在外锅本体11的凹形缺口12处，使得把手21的手握部低于锅盖的下端面，确保把手21的设置不会干涉锅盖与外锅10的盖合。
所述锅体组件设在底座50上。锅盖组件40包括外锅10和内锅20。外锅10的横截面形状为椭圆形，外锅10的侧周壁横截面具有彼此正交的长轴m和 短轴n。外锅10在长轴m方向上的相对侧壁分别向下内凹形成缺口12。外锅10在短轴n方向的侧壁的顶端向外延伸形成锅沿，从而方便第一卡扣31和第二卡扣32夹持外锅10。
内锅20的横截面形状同样为椭圆形，内锅20设在外锅10内。内锅20的侧周壁横截面也具有彼此正交的长轴m和短轴n。内锅20长轴m的外侧壁上设有两个相对布置的把手21，两个把手21可以分别放置于外锅本体11对应的缺口12内。
锅盖组件40可拆卸地设在所述锅体组件上，所述锅盖锁紧组件可移动地设置在锅盖组件40上，所述锅盖锁紧组件包括在短轴n方向间隔设置的第一卡扣31和第二卡扣32且第一卡扣31和第二卡扣32在短轴n方向上彼此靠近以夹持外锅10的锅沿，以及彼此远离以松开外锅10的锅沿。
具体地，如图3和图4所示，在第一卡扣31和第二卡扣32夹持外锅10锅沿以使锅盖组件40扣紧锅体组件时，作为所述夹持位置。此时，第一卡扣31和第二卡扣32的一端外侧在短轴n方向上的距离L1大于等于缺口12在短轴n方向上的宽度，且小于等于缺口12在短轴n方向上的宽度的两倍。由此保证所述锅盖锁紧组件与外锅10的扣合强度，进而保证锅盖组件40与锅体组件可以紧密扣合。
第一卡扣31形成沿外锅10侧周壁的周向延伸且与对应位置的侧周壁轮廓线形状对应的弧形，第二卡扣32形成沿外锅10侧周壁的周向延伸且与对应位置的侧周壁轮廓线形状对应的弧形。第一卡扣31和第二卡扣32分别沿外锅10的短轴n方向间隔设置，且在所述夹持位置时，第一卡扣31和第二卡扣32分别与外锅10短轴n方向上的侧壁顶部边缘对应，从而将椭圆形烹饪器具1锁紧，使得烹饪器具1的外锅10与锅盖组件40扣合稳定。
根据本发明实施例的烹饪器具1，通过将所述锅盖锁紧组件与外锅10之间的配合满足上述关系，可以提高所述锅盖锁紧组件与外锅10扣合强度，减小因结构强度不均，导致承力状态出现不稳定现象。
可选地，第一卡扣31和第二卡扣32上设有配合平台420和安装平台410，安装平台410突出于卡扣的上表面，这样可以便于在安装平台410上连接其他零部件(例如导向板470等)，配合平台420位于卡扣的侧壁，并且安装平台410与配合平台420之间彼此临靠，且安装平台410位于配合平台420的内侧，也就是说，配合平台420位于卡扣的侧壁上沿，且在安装平台410的外侧，同时与位于卡扣上表面的安装平台410之间彼此临靠。
这样便于将卡扣与导向板等部件连接，在卡扣上设置配合平台420，并且使得配合平台420与安装平台410彼此临靠且位于安装平台410的外侧，这样，在连接外观塑料件480时，可以将外观塑料件480定位在配合平台420上，从而在遮蔽安装平台410的同时，便于装配、固定，保持装配后整体的外观效果。
如图34所示，在本发明的一些实施例中，至少两个卡扣关于长轴对称布置，从而使得关于长轴对称布置的两个卡扣之间的间距较短，便于与其配合的导向板470与其他零部件之间的连接，并且，每个卡扣关于短轴对称，也就是说，卡扣布置在短轴的两端，这样，在锁紧时，可以减少卡扣以及外锅10与卡扣连接处的受力不均，从而降低由此导致的形变。
如图30所示，在一些示例中，配合平台420的宽度为C可以取0.2mm和5mm之间得任意值，例如，配合平台420的宽度C可以0.2mm，也可以为2mm、5mm或其他值，本领域技术人员可以根据实际设计例如塑料件480的尺寸等进行调整，以保证便于外观塑料件480的定位、连接。优选地，配合平台420的宽度C可以为0.2mm-2mm，这样在便于连接塑料件480的同时，也可以保持 外观效果。
如图29、图34所示，在一些示例中，安装平台410设在卡扣长度方向上且位于卡扣的中部，也就是说，安装平台410可以设在卡扣弧长长度方向中部，这样，在锁紧时，通过与安装平台410相连的导向板470对卡扣施加拉力时，可以使得两个卡扣受力后能够沿相对方向移动，而且可以减少卡扣上的受力不均。
如图30，在一些实施例中，卡扣包括围板430、上夹板441和下夹板442，上夹板441与围板430的上沿相连，配合平台420和安装平台410设于上夹板441，下夹板442连接至围板430的下沿，并且，上夹板441、围板430以及下夹板442共同限定出卡槽450，卡槽450大致形成为弧形且卡槽450的开口方向朝向外锅10的径向内侧，这样，在装配时，可以利用卡槽450将锅盖组件40与外锅10之间锁紧。
如图29和图30，在一些示例中，安装平台410与上夹板441的其余部分之间、配合平台420与上夹板441的其余部分，配合平台420与围板430之间均采用圆滑过渡，这样，既可以避免轮廓棱角可能产生的意外损伤，同时，也能够提高外观效果。
如图31-图33，在一些实施例中，安装平台410设有安装孔460，安装孔460沿安装平台410的厚度方向贯通，安装孔460可以包括两个或者两个以上，这样导向板470通过铆钉铆接在安装平台410上的安装孔460，从而使卡扣可以沿椭圆的短轴方向靠近，进而实现锅盖组件40与外锅10之间锁紧。
如图33，安装孔460的至少一部分形成截锥形孔段461，并且截锥形孔段461的横截面积从上向下逐渐增大。例如，在本示例中，安装孔460包括：截锥形孔段461和连接在截锥形孔段461上端的直孔段462。在铆接过程中，通 过直孔段462的轴向高度保持定位的强度，避免尖角磨损，在挤压铆钉时，截锥形孔段461用于填充变形料，使铆接强度提高，铆接面平整、美观。
