为此，部分滤网通过设置复杂的凹槽结构对烟气进行过滤，能够对液滴进行引导和收集，但为了保证过滤效果，需要设置多层的凹槽结构以增加气流的流路的复杂性，多层的凹槽结构加工工艺复杂，难度大且成本高。

下面参考附图描述根据本申请实施例的组合灶的滤网10。
如图1-图6所示，根据本申请实施例的组合灶的滤网10适于安装在组合灶1的灶台面20内且上表面为迎风侧(上下方向如图中的箭头所示)。
具体而言，如图5和图6所示，组合灶的滤网10可以邻近组合灶1的灶台面20的中心处设置，风机30可以设在滤网10的下方，组合灶1的加热区域可以位于滤网10的两侧，滤网10上方可以设有进风圈50，风机30可以连接有排风管40。
组合灶1通过将油烟吸入位置设置在灶台面20上，不同于设置在上方高处的烟机或组合灶，可以便于对烹饪食物时产生的水汽进行收集，适用于蒸煮等产生水汽较多的烹饪方式，提高组合灶1的针对性和适用性。
组合灶1运行时，气流从滤网10的上方流经滤网10过滤后向下进入风机30和排风管40。
组合灶的滤网10包括第一网体100和第二网体200。
第一网体100上设有多个网孔101，第一网体100为波纹状具有多个波峰110和多个波谷120，波峰110高于波谷120。第二网体200位于第一网体100下方，第二网体200 上设有多个间隔设置的导液槽210，多个导液槽210分别位于所述第一网体的所述波谷下方，相邻两个导液槽210之间形成有过风口201。
本领域的技术人员可以理解的是，对于第一网体100的面结构的波峰和波谷，并非仅指第一网体100上的某一点，而是指沿面结构延伸的线。
下面参考附图描述根据本申请实施例的组合灶的滤网10的工作过程。
烟气被吸入后，先经过第一网体100，与第一网体100碰撞和冷凝，使烟气中的水汽和油滴附着在第一网体100上，并逐渐汇聚至第一网体100的波谷120处，通过设置第二网体200，利用第二网体200的导液槽210对第一网体100拦截的水汽和油滴进行收集和引导，之后气流通过第二网体200的过风口201进入后续风道中。
根据本申请实施例的组合灶的滤网10，通过在迎风侧设置第一网体100，烟气先经过第一网体100，经过第一网体100的碰撞和冷凝，使烟气中的水汽和油滴附着在第一网体100上，并通过设置第二网体200，利用第二网体200的导液槽210对第一网体100拦截的水汽和油滴进行收集和引导，避免液滴直接滴入风道或被气流带入后续风道中，一方面相比相关技术中简单网状结构的滤网，气流先经过第一网体100再经过第二网体200，不仅可以使气流具有较为复杂的流路，以便于保证对油烟的拦截效果，而且可以利用第二网体200对液滴进行收集和引导，避免液滴进入后续风道，保证对油烟的过滤效果，另一方面相比相关技术中多层槽凹槽结构的滤网，只需要一层具有凹槽结构的第二网体200，其余可以使用加工难度较低的第一网体100，可以便于滤网10的加工和制造，降低滤网10的制造难度和成本。
并且，通过将第一网体100设置为波浪状，可以便于第一网体100上冷凝和碰撞的液滴汇聚在第一网体100的波谷120处，便于对液滴进行收集和引导，并通过在波谷120的下方设置导液槽210，可以使汇聚的液滴能够滴落至导液槽210内，以利用导液槽210对液滴进行收集和引导，而且由于导液槽210设置在波谷120的下方，可以避免气流直接将波谷120处汇聚的液滴带入后续的风道中，保证滤网10对液滴的拦截效果。
因此，根据本申请实施例的组合灶的滤网10具有过滤效果好、成本低等优点。
下面参考附图描述根据本申请具体实施例的组合灶的滤网10。
在本申请的一些具体实施例中，如图1-图6所示，组合灶的滤网10包括第一网体100和第二网体200。
具体地，如图1所示，多个导液槽210分别与多个波谷120在上下方向上一一对应。这样可以使每个波谷120下方均设有导液槽210，便于保证对第一网体100上液滴的收集效果，而且可以保证第二网体200的出风效果。
有利地，如图1-图4所示，多个导液槽210的长度方向平行，多个波峰110的长度方向平行，多个波谷120的长度方向平行，每个导液槽210的长度方向和与其对应的波谷120的长度方向平行。这样可以进一步保证导液槽210对第一网体100上液滴的收集 效果。
更为有利地，如图1所示，在水平方向上波谷120位于对应的导液槽210的中心处。这样可以便于保证液滴准确落入导液槽210内，进一步保证第二网体200对液滴的收集效果。
可选地，相邻两个波峰110之间的距离为80-160毫米。这样可以便于控制第一网体100的表面积，增大第一网体100与液滴的碰撞几率，提高对烟气的拦截过滤效果，提高油脂分离度。
进一步地，第一网体100为多个且沿上下方向排列。具体而言，第一网体100可以为1-5个。这样可以利用多层第一网体100对烟气进行拦截，进一步提高液滴的碰撞几率。
图1-图5示出了根据本申请一个具体示例的组合灶的滤网10。如图1-图3所示，第一网体100周围围绕有第一围板130，第二网体200周围围绕有第二围板220，第二围板220上设有排液口221。这样一方面可以便于第一网体100和第二网体200的定型和安装，一方面可以利用第二围板220对第二网体200的导液槽210收集的液滴进行引导，使液滴汇聚至第二围板220的排液口221处集中排出。
有利地，排液口221位于第二围板220长度方向的端部。这样可以便于液滴的汇聚和排出。
具体而言，第一围板130和第二围板220在长度方向的两端为向外凸出的弧形板。这样可以使滤网10的结构更加合理。
具体地，第一围板130的上边沿和下边沿以及第二围板220上的上边沿和下边沿具有向内延伸的内翻边。这样可以利用第一围板130和第二围板220包覆第一网体100和第二网体200。
第一围板130的上边沿的内翻边的内边沿设有向下延伸的下翻边。这样可以利用该下翻边进一步对第一网体100进行包覆。
具体而言，第一网体100由板材弯曲并开设圆形或多边形的网孔101形成，或由金属丝编制而成，第一围板130包覆第一网体100的外边沿。具体而言，网孔101为四边形孔且网孔101长度方向沿滤网10的宽度方向定向。第二网体200由多个压铸条间隔排列而成，第二围板220包覆多个压铸条的两端。
具体而言，多个网孔101沿滤网10的长度方向间隔排列成多行，每行包括沿滤网的宽度方向间隔排列的多个。这样可以使多个网孔101在第一网体100上形成阵列排布，保证通风的情况下提高对烟气的拦截效果。
更为有利地，如图5所示，滤网10与水平面倾斜预定角度a。具体而言，排液口221邻近滤网10的下端设置。这样可以利用重力将液滴汇聚至排液口221处，便于液滴的集中排出。
可选地，如图5所示，预定角度a为0-15度。具体而言，预定角度a为6-10度。这样可以在保证滤网10的迎风面积的情况下促使液滴汇聚至排液口221处。
更为具体地，第二网体200包括多个槽体，每个所述槽体上表面形成有导液槽210，多个所述槽体间隔设置且每相邻两个所述槽体之间形成有所述过风口201。这样可以便于导液槽210和过风口201的形成，便于第二网体200的形成。
进一步地，多个所述槽体沿滤网10的长度方向定向且沿滤网10的宽度方向间隔设置。具体而言，多个波峰110沿滤网10的长度方向定向且沿滤网10的宽度方向间隔排列，多个波谷120沿滤网10的长度方向定向且沿滤网10的宽度方向间隔排列。这样可以便于第二网体200的设置。
具体而言，所述槽体的底壁为U形或V形。这样可以便于导液槽210的形成，便于对液滴进行收集和引导。
第一网体100的波峰110和波谷120均圆弧过渡。这样可以便于液滴的汇聚，而且可以避免产生死角，便于第一网体100的清理。

本领域的技术人员可以理解的是，“波纹状”可以为弧形波纹也可以为折线形波纹。对于第一网体100的面结构的波峰和波谷，并非仅指第一网体100上的某一点，而是指沿面结构延伸的线。
下面参考附图描述根据本申请实施例的组合灶的滤网10的工作过程。
烟气被吸入后，先经过第一网体100，与第一网体100碰撞和冷凝，使烟气中的水汽和油滴附着在第一网体100上，并逐渐汇聚至第一网体100的波谷120处，通过设置第二网体200，利用第二网体200的导液槽210对第一网体100拦截的水汽和油滴进行收集和引导，之后气流通过第二网体200的过风口201进入后续风道中。
根据本申请实施例的组合灶的滤网10，通过在迎风侧设置第一网体100，烟气先经过第一网体100，经过第一网体100的碰撞和冷凝，使烟气中的水汽和油滴附着在第一网体100上，并通过设置第二网体200，利用第二网体200的导液槽210对第一网体100拦截的水汽和油滴进行收集和引导，避免液滴直接滴入风道或被气流带入后续风道中，一方面相比相关技术中简单网状结构的滤网，气流先经过第一网体100再经过第二网体200，不仅可以使气流具有较为复杂的流路，以便于保证对油烟的拦截效果，而且可以利用第二网体200对液滴进行收集和引导，避免液滴进入后续风道，保证对油烟的过滤效果，另一方面相比相关技术中多层槽凹槽结构的滤网，只需要一层具有凹槽结构的第二网体200，其余可以使用加工难度较低的第一网体100，可以便于滤网10的加工和制造，降低滤网10的制造难度和成本。
并且，通过将第一网体100设置为波浪状，可以便于第一网体100上冷凝和碰撞的液滴汇聚在第一网体100的波谷120处，便于对液滴进行收集和引导，并通过在波谷120的下方设置导液槽210，可以使汇聚的液滴能够滴落至导液槽210内，以利用导液槽210对液滴进行收集和引导，而且由于导液槽210设置在波谷120的下方，可以避免气流直接将波谷120处汇聚的液滴带入后续的风道中，保证滤网10对液滴的拦截效果。
此外，通过设置第一围板130和第二围板220，第二围板220套设在第一围板130外。这样一方面可以便于第一网体100和第二网体200的定型和安装，而且利用第一围板130和第二围板220的相互套设配合进行定位，可以便于第一网体100和第二网体200的相互连接，便于保证第一网体100和第二网体200的相对位置。
因此，根据本申请实施例的组合灶的滤网10具有过滤效果好、成本低等优点。
下面参考附图描述根据本申请具体实施例的组合灶的滤网10。
在本申请的一些具体实施例中，如图5-图10所示，组合灶的滤网10包括第一网体100和第二网体200。
具体地，第一围板130和第二围板220中位于外侧的一个上设有外凸耳222，外凸耳222上设有安装孔223，第一围板130和第二围板220中位于内侧的一个上设有装配孔131，第一网体100和第二网体200通过配合在安装孔223和装配孔131内的紧固件相连。这样可以便于第一网体100和第二网体200的固定，便于提高第一网体100和第二网体200的相对位置精度。
有利地，如图7和图8所示，第一围板130和第二围板220中位于内侧的一个上设 有把手300。这样用户在移动滤网10时可以通过操作把手300对滤网10进行移动，避免用户直接接触第一网体100和第二网体200，提高用户使用时的便利性和舒适性。
更为具体地，如图1-图4所示，第一围板130和第二围板220中位于内侧的一个上设有内凸耳132，内凸耳132上设有过孔133，把手300穿过过孔133。这样可以便于把手300的安装。
更为有利地，如图7-图10所示，内凸耳132为两个且外凸耳222为两个，把手300的两端分别穿过两个内凸耳132的过孔133，两个内凸耳132和两个外凸耳222位于同一直线上，两个外凸耳222分别止档把手300的两端以防止把手300脱离过孔133。这样可以利用外凸耳222止档把手300，避免把手300松脱，保证把手300安装后的可靠性。
具体而言，第二围板220位于第一围板130外。在安装时，先将把手300的一端穿过其中一个内凸耳132的过孔133，调整把手300在轴向上的位置，将把手300的另一端穿过另一个内凸耳132的过孔133，之后将第二围板220套设在第一围板130外，此时外凸耳222止档把手300，最后安装紧固件完成滤网10的装配。
本领域的技术人员可以理解的是，所述紧固件包括但不限于螺钉、螺栓或铆钉。
具体而言，把手300可以为直杆状或中部具有凸出两端的折弯段。
优选地，把手300包括两个平行段和连接两个所述平行段的折弯段，两个所述平行段的中心轴线重合，所述折弯段凸出两个所述平行段。两个所述平行段分别可转动且可沿轴向移动地配合在两个内凸耳132的过孔133内。两个外凸耳222分别止档两个所述平行段以限制把手300在所述平行段轴向上的移动。
图9示出了根据本申请一个具体示例的滤网10。如图3所示，第二网体200为一体件。这样可以便于第二网体200的制造，简化装配和制造工艺。
具体地，如图9所示，第二网体200由板材上开设多个条形的过风口201形成，每个过风口201设有围绕该过风口201且向上翻折的上翻边224，相邻两个上翻边224之间构成导液槽210。这样可以便于第二网体200的形成，而且在开设过风口201时，可以直接利用过风口201的翻边构成导液槽210，大大简化第二网体200的制造难度。
有利地，如图9所示，第二围板220与第二网体200一体形成。这样可以进一步减少滤网10的零件数量，便于滤网10的装配。
可选地，波谷120与导液槽210之间的最小距离大于等于3毫米。这样可以保证滤网10的过风风量。
进一步地，导液槽210的最小宽度大于等于3毫米。这样可以保证导液槽210能够可靠地收集第一网体100汇聚的液滴，提高滤网10对油烟的过滤收集效果。
更为有利地，第一围板130的上边沿高于第二围板220，第一围板130上与第二围板220重叠的部分以外的部分设有海绵。这样可以利用海绵密封滤网10与组合灶1的箱体之间的缝隙，进一步提高对油烟的过滤收集效果。
在本申请的另一个具体实施例中，第一围板130和第二围板220中的一个上设有定位凸起且另一个上设有弹性限位片，所述定位凸起与所述弹性限位片可脱离地配合相连。这样同样可以实现第一围板130和第二围板220的连接。
图7-图10示出了根据本申请一个具体示例的组合灶的滤网10。
具体地，如图7所示，多个导液槽210分别与多个波谷120在上下方向上一一对应。这样可以使每个波谷120下方均设有导液槽210，便于保证对第一网体100上液滴的收集效果，而且可以保证第二网体200的出风效果。
有利地，如图7-图10所示，多个导液槽210的长度方向平行，多个波峰110的长度方向平行，多个波谷120的长度方向平行，每个导液槽210的长度方向和与其对应的波谷120的长度方向平行。这样可以进一步保证导液槽210对第一网体100上液滴的收集效果。
更为有利地，如图7所示，在水平方向上波谷120位于对应的导液槽210的中心处。这样可以便于保证液滴准确落入导液槽210内，进一步保证第二网体200对液滴的收集效果。
可选地，相邻两个波峰110之间的距离为80-160毫米。这样可以便于控制第一网体100的表面积，增大第一网体100与液滴的碰撞几率，提高对烟气的拦截过滤效果，提高油脂分离度。
进一步地，第一网体100为多个且沿上下方向排列。具体而言，第一网体100可以为1-5个。这样可以利用多层第一网体100对烟气进行拦截，进一步提高液滴的碰撞几率。
本领域的技术人员可以理解的是，第一网体100上方也可以设置其他结构的滤网以构成多层滤网结构。
图6-图7示出了根据本申请一个具体示例的组合灶的滤网10。如图7-图9所示，第一网体100周围围绕有第一围板130，第二网体200周围围绕有第二围板220，第二围板220上设有排液口221。这样一方面可以便于第一网体100和第二网体200的定型和安装，一方面可以利用第二围板220对第二网体200的导液槽210收集的液滴进行引导，使液滴汇聚至第二围板220的排液口221处集中排出。
具体而言，第一围板130上设有避让排液口221的避让槽。
有利地，排液口221位于第二围板220长度方向的端部。这样可以便于液滴的汇聚和排出。
具体而言，第一围板130和第二围板220在长度方向的两端为向外凸出的弧形板。这样可以使滤网10的结构更加合理。
具体地，第一围板130的上边沿和下边沿具有向内延伸的内翻边。这样可以利用第一围板130包覆第一网体100。
在本申请的另一个具体实施例中，第二围板130的上边沿和下边沿具有向内延伸的内翻边。第一围板130的上边沿的内翻边的内边沿设有向下延伸的下翻边。这样可以利用该下翻边进一步对第一网体100进行包覆。
具体而言，第一网体100由板材弯曲并开设圆形或多边形的网孔形成，或由金属丝编制而成，第一围板130包覆第一网体100的外边沿。具体而言，网孔为四边形孔且网孔长度方向沿滤网10的宽度方向定向。第二网体200由多个压铸条间隔排列而成，第二围板220包覆多个压铸条的两端。
优选地，第一网体100可以为对称结构。第一网体100的波纹结构可以为弧形波纹或折线形波纹。
具体而言，多个网孔沿滤网10的长度方向间隔排列成多行，每行包括沿滤网的宽度方向间隔排列的多个。这样可以使多个网孔在第一网体100上形成阵列排布，保证通风的情况下提高对烟气的拦截效果。
更为有利地，如图5所示，滤网10与水平面倾斜预定角度a。具体而言，排液口221邻近滤网10的下端设置。这样可以利用重力将液滴汇聚至排液口221处，便于液滴的集中排出。
可选地，如图5所示，预定角度a为0-15度。具体而言，预定角度a为6-10度。这样可以在保证滤网10的迎风面积的情况下促使液滴汇聚至排液口221处。
在本申请的另一个实施例中，第二网体200包括多个槽体，每个所述槽体上表面形成有导液槽210，多个所述槽体间隔设置且每相邻两个所述槽体之间形成有所述过风口201。这样可以便于导液槽210和过风口201的形成，便于第二网体200的形成。
进一步地，多个所述槽体沿滤网10的长度方向定向且沿滤网10的宽度方向间隔设置。具体而言，多个波峰110沿滤网10的长度方向定向且沿滤网10的宽度方向间隔排列，多个波谷120沿滤网10的长度方向定向且沿滤网10的宽度方向间隔排列。这样可以便于第二网体200的设置。
具体而言，所述槽体的底壁为U形或V形。这样可以便于导液槽210的形成，便于对液滴进行收集和引导。
第一网体100的波峰110和波谷120均圆弧过渡。这样可以便于液滴的汇聚，而且可以避免产生死角，便于第一网体100的清理。
