下面参考附图介绍本申请第一方面实施例的过滤系统。
结合图1-图25所示，本申请第一方面实施例的过滤系统，主要包括：壳体1、粉碎组件3、过滤组件、第一抽吸件4和第二抽吸件(图中未示出)。其中，壳体1内并排设有第一腔室和第二腔室，第一腔室的顶部设有水渣混合物入口，便于水渣混合物进入；第一腔室的底部和第二腔室的底部经通道2相互连通，便于经粉碎组件3粉碎后的水渣混合物通过。本申请实施例通过将通道2设置于第一腔室和第二腔室的底部，当过滤系统处于过滤过程时，便于第一抽吸件4将粉碎后的水渣混合物经底部的通道2吸入第二腔室内的过滤组件过滤，当过滤系统处于排渣过程时，便于第二抽吸件将过滤后的残渣再次经底部的通道2吸出以进行排放。
粉碎组件3设置于第一腔室内，且粉碎组件3适于粉碎进入第一腔室的水渣混合物中的残渣，通过粉碎组件3可以自动对水渣混合物中的残渣粉碎至合适的排放尺寸，避免堵塞通道2和过滤组件，进而保证第一抽吸件4和第二抽吸件的正常工作。本申请实施例中粉碎组件3的具体类型不作特别限制，只要可以对残渣起到粉碎的作用即可。例如可以采用类似扇叶的旋转刀具，也可以采用滚刀结构。
过滤组件可旋转设置于第二腔室内，且过滤组件的开口向下朝向通道2，便于第一抽吸件4抽吸时，粉碎后的水渣混合物经底部的通道2吸入过滤组件内过滤。
第一抽吸件4设置于壳体1上并与第二腔室连通，以将粉碎后的水渣混合物经底部的通道2吸入第二腔室内的过滤组件进行过滤。本申请实施例第一抽吸件4的具体类型不作特别限制，只要可以对水渣混合物起到抽吸的作用即可，例如可以采用抽水泵。
第二抽吸件设置于壳体1上并与第一腔室连通，在第一抽吸件4停机的情况下，即过滤完成后，第二抽吸件适于将第一腔室和/或第二腔室内的残渣经通道2吸出进行排放。
本申请实施例第二抽吸件的具体类型不作特别限制，只要可以对残渣起到抽吸的作用即可，例如可以采用排渣泵。并且第二抽吸件和第一抽吸件4分别相对连接于通道2的两端，避免过滤过程和排渣过程造成干涉。
根据本申请实施例的过滤系统，残渣及待过滤水的水渣混合物进入第一腔室内，通过粉碎组件3自动对残渣粉碎至合适的排放尺寸，避免堵塞后续通道2和过滤组件，进而保证第一抽吸件4和第二抽吸件的正常工作；通过第一抽吸件4将粉碎后的残渣及待过滤水经底部的通道2吸入第二腔室内的过滤组件中进行过滤，在过滤过程中，通过过滤组件旋转可以产生离心力，在离心力的作用下，吸入过滤组件的残渣可以贴附于过滤组件不掉落，过滤后的水经第二腔室排出，过滤完成后，第一抽吸件4停机，残渣在重力和第二抽吸件的抽吸力下落至底部的通道2，进而被第二抽吸件吸出排放。因此，本申请过滤系统可以有效分离水渣混合物，实现残渣的自动化处理，无需人工对残渣进行处理，提高用户的使用体验；并且本申请过滤过程与排渣过程共用同一通道2，无需另设排渣通道结构，优化了整个过滤系统的内部结构。
根据本申请的一个实施例，过滤组件包括第一滤网5以及清洁装置6，第一滤网5可旋转设置于第二腔室内，用于对粉碎后的水渣混合物进行过滤分离，清洁装置6设置于第一滤网5内，清洁装置6适于与第一滤网5相对旋转以刮除第一滤网5上的部分残渣，以在第一滤网5上形成与第二腔室连通的出水区域，便于过滤出水。这里提及的清洁装置6与第一滤网5相对旋转是指，清洁装置6在第一驱动件(图中未示出)的带动下旋转且与第一滤网5具有转速差，或者只有第一滤网5在第一驱动件的带动下旋转，可根据实际工况进行设计。第一驱动件一般为电机、马达等装置。
应当理解的是，本申请实施例第一滤网5设有过滤腔，清洁装置6设置于过滤腔内，第一抽吸件4将粉碎后的水渣混合物经底部的通道2吸入第一滤网5的过滤腔内进行过滤，并且在过滤过程中，由于第一抽吸件4持续产生的吸力和第一滤网5旋转产生的离心力，使得水渣混合物中的残渣可以暂时收集于第一滤网5的过滤腔内，且部分残渣甚至会贴附于第一滤网5邻近第一抽吸件4的侧壁上，进而堵塞第一滤网5的过滤孔，导致出水效果不理想，此时，通过设置与第一滤网5相对旋转的清洁装置6，可以刮除第一滤网5上的部分残渣，在第一滤网5上形成与第二腔室连通的出水区域，过滤后的水可以经出水区域进入第二腔室，然后排出。因此，本申请通过设置清洁装置6，可以有效提升过滤出水效果。
根据本申请的一个实施例，第一驱动件设置于第二腔室的底部，第一驱动件分别与第一滤网5和清洁装置6连接，以驱动第一滤网5和清洁装置6具有不同的旋转速度，进而通过清洁装置6可以刮除第一滤网5上的部分残渣，使部分残渣与第一滤网5分离。第一驱动件可以实现同轴双输出，或者其他类型的电机，或者第一驱动件设有两个，分别与第一滤网5和清洁装置6对应连接。
如图18-图22所示，清洁装置6设置于第一滤网5内，清洁装置6主要包括安装架601和接触部602，安装架601可与第一驱动件的输出轴连接，并在第一驱动件的驱动下可旋转，从而带动整个清洁装置6可旋转；接触部602连接于安装架601上，并与第一滤网5的内壁相接触，当清洁装置6与第一滤网5具有转速差时，接触部602可以将第一滤网5上的部分残渣刮出以形成出水区域，便于过滤出水。
在一些实施例中，如图22所示，安装架601大体上可包括连接部分6011以及架体部分6012。其中，连接部分6011与第一驱动件的输出轴同轴设置，并在第一驱动件的驱动下可旋转。而架体部分6012的一侧与连接部分6011相连接，且接触部602可设置于该架体部分6012远离连接部分6011的一侧。其中，接触部602的数量与架体部分6012的数量相同或者为一一对应。
在一些实施例中，架体部分6012可以与连接部分6011一体成型。当然，在其他实施例中，该架体部分6012也可以与连接部分6011分体成型。 而且，架体部分6012的形状不限定于图中所示的具有中空部分的框体结构，在一些实施例中，架体部分6012也可以为实体结构。
在一些实施例中，清洁装置6可以包括至少一个架体部分6012，且每一架体部分6012的外侧均设有接触部602。当清洁装置6包括两个架体部分6012时，接触部602的数量同样为两个，两个架体部分6012可以关于连接部分6011的轴向对称设置。当然，在其他实施例中，还可以设置三个或三个以上的架体部分6012以及接触部602。例如，在图22所示的实施例中，该架体部分6012和接触部602的数量均为三个，且三个架体部分6012沿连接部分6011的周向等距离地均匀分布。本申请对架体部分6012及接触部602的数量、材料以及尺寸不做限制。
在一些实施例中，该接触部602可以为刮条，且该接触部602可采用例如硅胶、橡胶等材料制成。
根据本申请的一个实施例，如图18-图21所示，第一滤网5的形状为圆柱形，当然也可以为其他具有过滤腔的形状，例如圆锥体、方体等形状。第一滤网5的外壁与第二腔室的内壁间隔设置以形成回水腔7，第一抽吸件4通过出水管道8与回水腔7的出水口701相连，回水腔7适于通过第一滤网5的出水区域与第一滤网5的内部连通，便于过滤后的水流至回水腔7内。
需要说明的是，本申请通过设置回水腔7，可以使得过滤后的水持续进入回水腔7，进而持续充满整个出水管道8而不会掺杂空气，可以有效地解决第一抽吸件4在抽水过程中导致出水口701位置出现的抽空气问题，即出现空吸现象，进而提高过滤效率，且保护了第一抽吸件4。
根据本申请的一个实施例，如图4和图20所示，第二腔室的内壁上环布设有支撑部9，第一滤网5的底部支撑于支撑部9上，使得第一滤网5的外壁与第二腔室的内壁具有间隔，进而将整个第二腔室分为上部的回水腔7和下部通道2的部分，第一滤网5的底部入口与通道2相连通。这里提及的“支撑于”可以理解为，该支撑部9仅起到支撑作用，而不是固定作用。因此，第一滤网5可以相对该支撑部9旋转。
根据本申请的一个实施例，清洁装置6的接触部602可以与支撑部9的内壁固定连接，第一驱动件可与第一滤网5连接，以驱动第一滤网5旋 转，进而通过清洁装置6刮除第一滤网5上的部分残渣。并且，通过第一滤网5的旋转，可以产生离心力，使得水渣混合物的残渣可以保持在第一滤网5的过滤腔内，待过滤过程结束后，第一滤网5停止旋转，残渣在重力和第二抽吸件的吸力作用下落至底部的通道2内，进而被第二抽吸件经排渣管道27吸出排放。
如图21所示，第一滤网5主要包括滤网框架501、滤网主体502和连接支架503，滤网主体502设置于滤网框架501上，连接支架503的第一端与滤网框架501的底部内壁相连，连接支架503的第二端延伸至滤网框架501的中心轴位置，且连接支架503的第二端设有连接孔504，第一驱动件的输出轴与连接支架503的连接孔504同轴相连，从而驱动滤网框架501旋转，进而带动整个第一滤网5旋转。
在一些实施例中，第一滤网5可以包括三个连接支架503，且三个连接支架503的第二端相共设一个连接孔504，三个连接支架503围绕该连接孔504周向均匀分布，一方面，便于水渣混合物进入第一滤网5，另一方面提高第一滤网5的整体结构强度和旋转稳定性。
在实际粉碎工况中，由于残渣种类的不同，相关技术的粉碎组件粉碎尺寸较大的块状残渣或较硬的残渣时，无法将其完全粉碎，粉碎效果差，并且容易出现卡料现象，导致粉碎效率低，进而会影响过滤效率。
因此，为解决上述技术问题，本申请实施例提供一种粉碎组件3，结合图4-图12所示，粉碎组件3包括粉碎装置，粉碎装置主要包括滚刀10和隔片11。其中，两组滚刀10并排相对设置，且两组滚刀10可对向转动进行咬合以产生碾压力对残渣进行粉碎，每组滚刀10包括转轴1001及多个齿片1002，多个齿片1002沿轴向套设于转轴1001上，两组滚刀10的多个齿片1002交错布置以在两组滚刀10之间形成第一粉碎区域，当水渣混合物的残渣与齿片1002接触时，水渣混合物的残渣被带进两组滚刀10交错设置的齿片1002之间，实现对进入第一粉碎区域的水渣混合物进行一次粉碎。本申请实施例两组滚刀10齿片1002的交错设置，可以理解为：第一组滚刀10的齿片1002位于第二组滚刀10相邻齿片1002的间隔内，第二组滚刀10的齿片1002位于第一组滚刀10相邻齿片1002的间隔内；并且由于两组滚刀10交错设置，则第一组滚刀10的首个齿片1002和第 二组滚刀10的最后一个齿片1002不在间隔内。
需要说明的是，本申请实施例中，粉碎装置包括的滚刀10数量并不局限为两组，但是不管滚刀10的数量为多少，都至少包括相对设置的两组滚刀10。
隔片11与至少一组滚刀10对应，即隔片11可以设置一组与一组滚刀10对应，也可以设置两组分别与两组滚刀10对应。一般而言，隔片11与两组滚刀10对应时的粉碎效果比隔片11对应一组滚刀10时的粉碎效果更好，可根据实际粉碎工况作相应设计。例如：当粉碎装置用于粉碎尺寸较小的颗粒状残渣或硬度较软的残渣时，则该种粉碎装置可以采用隔片11与一组滚刀10对应的形式；当粉碎装置用于粉碎尺寸较大的块状残渣或硬物时，则该种粉碎装置可以采用隔片11与两组滚刀10对应的形式，以提高粉碎效果，将块状残渣或硬物充分粉碎至合适的排放尺寸。
隔片11与同组滚刀10的齿片1002交错设置以进行咬合，且隔片11由齿片1002的侧部向齿片1002的底部延伸并与齿片1002的底部之间形成第二粉碎区域，当水渣混合物经第一粉碎区域粉碎后进入底部的第二粉碎区域时，水渣混合物进一步被带进交错设置的隔片11与齿片1002之间，实现对进入第二粉碎区域的水渣混合物进行二次粉碎，有效提高粉碎效果，实现将水渣混合物的残渣粉碎至合适的排放尺寸。本申请实施例隔片11与同组滚刀10的齿片1002交错设置，可以理解为：隔片11位于滚刀10相邻齿片1002的间隔内，滚刀10齿片1002位于相邻隔片11的间隔内，并且由于隔片11与同组滚刀10的齿片1002交错设置，则首个齿片1002和最后一个隔片11不在间隔内。
本申请实施例的粉碎装置，通过两组滚刀10的齿片1002交错布置以在两组滚刀10之间形成第一粉碎区域，当水渣混合物进入第一粉碎区域时，可以对水渣混合物中的残渣进行一次粉碎；通过隔片11与滚刀10齿片1002交错设置并且隔片11的底部与齿片1002的底部之间形成第二粉碎区域，当水渣混合物经第一粉碎区域粉碎后进入底部的第二粉碎区域时，可以对水渣混合物中的残渣进行二次粉碎，进而提高粉碎效果，可以将水渣混合物中的块状残渣或硬物有效粉碎至合适的排放尺寸，例如小于3mm；此外，通过隔片11的侧部可以将滚刀10齿片1002上的残渣刮下，防止残 渣粘附于滚刀10的齿片1002上，进而防止出现卡料现象。因此，本申请实施例的粉碎装置具有使用方便、粉碎效果好及粉碎效率高等特点。
根据本申请的一个实施例，如图7和图8所示，隔片11包括支承部1101和限位部1102，沿粉碎装置的高度方向，支承部1101位于滚刀10齿片1002的底部并与滚刀10齿片1002咬合以形成第二粉碎区域；限位部1102与支承部1101相连，且限位部1102位于齿片1002的侧部并设有与滚刀10转轴1001相配合的限位槽1103。本申请实施例通过支承部1101，一方面可以对滚刀10进行支承，另一方面，可以与滚刀10齿片1002咬合以形成第二粉碎区域，实现对水渣混合物残渣的二次粉碎，有效提高粉碎效果；并且通过限位部1102，一方面，可以对滚刀10的转轴1001进行限位，便于滚刀10的安装。
另一方面，当水渣混合物进入底部的第二粉碎区域时，会被进一步粉碎，然后经粉碎装置的底部落至通道2内，但同时可能存在部分已粉碎的残渣粘附于滚刀10的齿片1002上，此时，通过限位部1102也可以将该部分残渣刮下，防止残渣粘附于齿片1002上，进而避免滚刀10出现卡料现象。
根据本申请的一个实施例，参照图8和图9所示，隔片11与两组滚刀10对应，即两组滚刀10分别对应设有隔片11，两组隔片11的支承部1101交错布置，支承部1101设有齿槽1104，第一组滚刀10齿片1002的刀齿1003与第二组隔片11支承部1101的齿槽1104咬合，且第二组滚刀10齿片1002的刀齿1003与第一组隔片11支承部1101的齿槽1104咬合，即两组滚刀10的齿片1002与各自相对的隔片11交叉咬合。本申请实施例通过交叉咬合设置，当水渣混合物被带至底部的第二粉碎区域时，可以对水渣混合物的残渣进行充分粉碎，进一步提高粉碎效果。
根据本申请的一个实施例，如图8所示，限位部1102的形状为弧形，且同一隔片11上的限位部1102的外侧面至滚刀10转轴1001的距离小于刀齿1003的齿尖至滚刀10转轴1001的距离，即通过将齿片1002的刀齿1003外露于限位部1102的外侧，可以便于通过水流对两侧齿片1002的刀齿1003进行冲洗，进一步防止卡料，进而提高粉碎效率。
根据本申请的一个实施例，如图8所示，隔片11还包括安装部1105， 安装部1105连接于限位部1102的上方，安装部1105设有第一安装孔1106，且多个隔片11的安装部1105的第一安装孔1106沿轴向相对齐，通过第一紧固螺栓贯穿所有第一安装孔1106后通过第一螺母实现紧固；并且支承部1101设有第二安装孔1107，多个隔片11的支承部1101的第二安装孔1107沿轴向相对齐，通过第二紧固螺栓贯穿所有第二安装孔1107后通过第二螺母实现紧固。
根据本申请的一个实施例，如图6-图8所示，每相邻两个隔片11的安装部1105之间设有隔板12，用于将相邻两个隔片11隔开；且隔板12设有第三安装孔1201，第三安装孔1201与第一安装孔1106相对齐，进而可以通过第一紧固螺栓贯穿所有第一安装孔1106和第三安装孔1201后通过第一螺母实现紧固。应当理解的是，本申请隔板12的安装位置应避免对滚刀10齿片1002的转动造成干涉。
根据本申请的一个实施例，如图10所示，滚刀10齿片1002的外周面沿周向间隔设有6-8个刀齿1003，换句话说，沿齿片1002的周向，在齿片1002的边缘间隔地设置有6-8个刀齿1003。
需要说明的是，如果单个齿片1002的刀齿1003小于6-8个，会使得滚刀10的咬合力增大，从而使得驱动滚刀旋转的第二驱动件的驱动力增大，进而会提高第二驱动件的能耗；如果单个齿片1002的刀齿1003大于6-8个，会使得齿片1002上的刀齿1003较为密集，水渣混合物中尺寸较大的块状残渣难以被咬合。具体的，因为刀齿数大于6-8个的话，使得块状残渣同时接触的刀齿1003增多，块状残渣难以被带入两组滚刀10刀齿1003之间的第一粉碎区域，从而导致无法有效粉碎残渣。因此，本申请实施例通过将齿片1002的刀齿1003设置为6-8个，可以在降低第二驱动件能耗的同时，保证水渣混合物中的残渣快速进入第一粉碎区域，以提高粉碎效果。
根据本申请的一个实施例，由于滚刀10同一转轴1001上相邻齿片1002的间距越小，与另一组齿片1002的摩擦力越大，从而使得驱动滚刀10旋转的第二驱动件的驱动力增大，进而会提高驱动件的能耗。因此，本申请将在滚刀10同一转轴1001上相邻齿片1002的间距设置为1.5mm-2.5mm，这样，既可以保证粉碎后残渣的颗粒大小达到排放要求，同时可以 减小运行过程中产生的额外摩擦力，进而降低第二驱动件的能耗。
根据本申请的一个实施例，如图10和图11所示，滚刀10同一转轴1001上多个齿片1002的刀齿1003沿轴向构成刀齿组，当齿片1002上设有多个刀齿1003，相应的，构成的刀齿组也为多组，在每组刀齿组中，多个刀齿1003相互错位以使每相邻两个齿片1002的刀齿1003之间均形成旋转位差，即相邻两个齿片1002相对于滚刀10转轴1001具有一定的偏转角度以使刀齿1003相互旋转错位，其中，齿片1002的偏转方向可以均为顺时针或均为逆时针，即沿同一旋转方向偏转，齿片1002的偏转方向也可以为部分顺时针，另一部分逆时针，即沿不同旋转方向偏转，可根据实际粉碎工况进行相应调节。本申请通过刀齿1003设置旋转位差，可以保证两组滚刀10的齿片1002充分咬合残渣，以提高粉碎效果。
在相关技术中，滚刀10转轴1001上多个齿片1002的刀齿1003沿轴向的正投影一般是重合设置，这样使得滚刀10受到的压力集中于轴向的刀齿，长时间粉碎块状残渣或硬物后，容易导致滚刀损坏。本申请通过刀齿1003设置旋转位差，可以使滚刀10受到的压力沿旋转位差进行相应分布，即压力沿滚刀10转轴1001的周面分散，进而可以分散滚刀10刀体的压力，避免压力过于集中，有利于保护滚刀10，进而延长粉碎装置的使用寿命。
根据本申请的一个实施例，相邻两个齿片1002刀齿1003的旋转位差的角度设置为4°-6°。
需要说明的是，本申请通过将旋转位差的角度设置为4°-6°，在满足咬合性能的前提下，同时满足滚刀10刀体的可制造性。另一方面，正因为这种刀体结构，可以实现在低速运转的情况下粉碎大尺寸的块状残渣或硬物，并且因为低转速运转，使得本申请实施例的粉碎装置可以实现低噪音工作。
根据本申请的一个实施例，如图10和图11所示，滚刀10同一转轴1001上多个齿片1002的刀齿1003沿轴向逐渐以一定的偏转角度相互错位以形成上述实施例的旋转位差。具体的，1号刀齿和2号刀齿为4°-6°(例如5°)的旋转位差，2号刀齿和3号刀齿也为4°-6°(例如5°)的旋转位差，以此类推，使沿同一偏转方向相邻刀齿1003之间形成一定角度的旋转位差，这样可以保证滚刀10充分咬合残渣，同时可以使滚刀10受到的压 力分散效果最大化。
根据本申请的一个实施例，滚刀10的转轴1001连接有第二驱动件，第二驱动件驱动转轴1001转动进而使滚刀10转动，第二驱动件可以驱动滚刀10处于47分呗以下的低噪音运行状态，防止产生噪音，提高粉碎装置的使用体验。具体的，通过调整第二驱动件的输入电压，将第二驱动件的转速降低，同时设定恒定电压，例如可以为100V-120V(满负荷是220V)，这样第二驱动件就可以输出恒定的低转速，例如可以为90RPM-120RPM，这样相比满负荷状态，低电压低转速情况下，噪音可以大幅度降低。此外，如果水渣混合物中具有难以粉碎且硬度较高的残渣时，可以实时提高第二驱动件的输入电压以满足瞬时的高扭力要求。当粉碎成功后，使第二驱动件的输入电压复原为低电压状态，这样，在整个过程中，使用者始终感觉是低噪音状态。
根据本申请的一个实施例，如图12所示，第二驱动件包括驱动电机13和变速箱14，驱动电机13通过变速箱14分别与两组滚刀10的转轴1001相连，从而驱动两组滚刀10旋转。具体的，变速箱14包括：箱体以及设置于箱体内的齿轮副，齿轮副包括第一传动轴141、第二传动轴142、第一齿轮143、第二齿轮144、第三齿轮145、第四齿轮146和第五齿轮147，第一传动轴141上设有第一齿轮143，第一齿轮143与驱动电机13输出轴上的齿槽啮合，第二传动轴142上设有第二齿轮144，第二齿轮144与第一传动轴141上的齿槽啮合，第一组滚刀10的转轴1001上设有第三齿轮145和第四齿轮146，第三齿轮145与第二传动轴142上的齿槽啮合，第二组滚刀10的转轴1001上设有第五齿轮147，第五齿轮147与第四齿轮146啮合。通过驱动电机13转动带动各个齿轮转动，进而带动两组滚刀10旋转。
根据本申请的一个实施例，结合图4和图5所示，粉碎装置还包括机壳15，机壳15的底部与通道2相连通，上述实施例的滚刀10及隔片11设置于机壳15内，机壳15上形成有进料口1501，进料口1501设置于机壳15的顶部且与壳体1的水渣混合物入口相对应，且进料口1501与滚刀10的第一粉碎区域相连通，机壳15的侧壁与滚刀10之间形成有适于过水的引流通道16，引流通道16与进料口1501相连通。其中，图5中箭头表 示水渣混合物流动方向，残渣和部分水流经进料口1501进入粉碎装置的第一粉碎区域进行一次粉碎后，然后落入底部的第二粉碎区域进行二次粉碎，充分粉碎后从进入底部通道2。
在实际粉碎工况中，由于可能存在部分粉碎后的粉末状残渣粘附于滚刀10的齿片1002上且未被隔片11刮下时，一方面会影响滚刀10的转动进而影响粉碎效果，严重时可能发生卡料现象，另一方面有可能滋生细菌，产生异味。因此，本申请通过设置引流通道16，使得另一部分水流经进料口1501流入两侧的引流通道16中，引流通道16将水流引流至滚刀10两侧的齿片1002刀齿1003上，对刀齿1003进行冲刷，这样在水流的冲刷清洗下，残留在刀齿1003上的物料很容易被冲走，实现对刀具的自清洁，避免出现卡料现象和产生异味。
根据本申请的一个实施例，在一种实现方式中，如图4和图5所示，粉碎装置机壳15的进料口1501与第一粉碎区域之间设有过滤装置，过滤装置包括滤斗17，滤斗17的侧壁设有与引流通道16连通的通孔1701。由于可能存在部分残渣会随水流进入引流通道16，影响刀具的自清洁效果和造成通道2堵塞，因此，本申请实施例通过设置滤斗17且滤斗17的侧壁设有通孔1701，可以对残渣进行过滤，使滤斗17内的水渣混合物的残渣可以集中进入滚刀10的第一粉碎区域，防止残渣不经过粉碎直接进入引流通道16内，可以进一步提高滚刀10的自清洁效果。
根据本申请的一个实施例，如图13-图16所示，沿着滤斗17的高度方向，在滤斗17上开设有过滤通道1702，水渣混合物中的残渣及部分待过滤的水经过过滤通道1702的入口流入过滤通道1702内，再经过滤通道1702底部的出料口1703流至粉碎装置的第一粉碎区域进行粉碎；滤斗17侧壁开设的通孔1701与过滤通道1702相连通，另一部分待过滤的水经通孔1701过滤后流入引流通道16，引流通道16将过滤后的水引流至滚刀10两侧的齿片1002刀齿1003上，对刀齿1003进行冲刷，实现对刀具的自清洁。通孔1701的具体数量不作特别限制，可根据实际工况进行调节。在本申请实施例中，通孔1701为多个，且多个通孔1701至少开设于滤斗17相对的两个侧壁，以使过滤后的水可以进入两侧的引流通道16对滚刀10两侧的刀齿1003进行冲刷，进一步提高自清洁效果。
在实际粉碎工况中，当粉碎的物料量较大时，会导致部分未被粉碎的水渣混合物聚集在滤斗17内且位于滚刀10第一粉碎区域的上方。当水渣混合物中混入质量相对较轻的异物，诸如牙签、牙线等细长物，会导致牙签、牙线等细长物漂浮在滤斗17的通孔1701附近，这就使得牙签、牙线等细长物不经过滚刀10粉碎而通过滤斗17的通孔1701进入引流通道16，进而落入底部的通道2内，造成堵塞，甚至会卡入第一抽吸件4和第二抽吸件，造成其损坏。
为解决上述技术问题，如图5和图17所示，本申请过滤装置还包括阻挡组件，阻挡组件设置于滤斗17的外侧，阻挡组件位于引流通道16内的上游且与滤斗17的通孔1701对应，这里提及的“对应”可以理解为，阻挡组件设置于通孔1701的出口处。阻挡组件与通孔1701的出口之间具有一定的间距，通过将阻挡组件间隔地设置于通孔1701的出口位置，可以在不妨碍水流通过的前提下，挡住牙签、牙线等细长物，防止牙签等细长物通过通孔1701进入引流通道16。
文中提及的“滤斗17高度方向”可以理解为从滤斗17入料口至出料口1703的方向，如图4、图5所示，滤斗17为竖直放置，则滤斗17的高度方向同样为竖直方向，在其他使用场景中，滤斗17也可以倾斜或水平放置，此时，滤斗17的高度方向同样倾斜或水平。
在本申请实施例中，阻挡组件包括第一阻挡件18和第二阻挡件19，第一阻挡件18和第二阻挡件19间隔设置，且在垂直于通孔1701的轴向的平面内，第一阻挡件18的正投影与第二阻挡件19的正投影部分重叠，滤斗17的外侧与第一阻挡件18之间形成有储水腔20，第一阻挡件18与第二阻挡件19之间形成有与储水腔20相连通的过流通道21，储水腔20经过流通道21与引流通道16相连通。
根据本申请的实施例，通过在滤斗17通孔1701的外侧且引流通道16的上游设置第一阻挡件18及第二阻挡件19，并将第一阻挡件18及第二阻挡件19间隔设置且使得二者在垂直于通孔1701的轴向的平面内的正投影部分重叠，其中，通孔1701的轴向即如图16中所示的虚线的方向。当牙签等细长物流入通孔1701时，牙签等细长物会被第一阻挡件18和第二阻挡件19中的至少一个阻挡，或者牙签等细长物也可以被卡在第一阻挡件 18与第二阻挡件19之间，这就使得牙签等细长物无法继续通过通孔1701。这样一来，本申请实施例通过上述设置的阻挡组件可以挡住牙签等细长物，防止其经通孔1701流至滤斗17外侧的引流通道16，避免后续通道2堵塞；并且经通孔1701过滤后的水至少部分流至储水腔20后再经过流通道21流入引流通道16中，另一部分水直接经过流通道21流入引流通道16中，这两部分经过过滤后的水经引流通道16可以一起流至滚刀10的两侧进行冲刷，冲刷后的水和粉碎后的残渣进入底部的通道2，进而被第一抽吸件4抽吸至第二腔室的第一滤网5内进一步过滤分离。
应当理解的是，本申请实施例中的过流通道21和储水腔20均与滤斗17的通孔1701相连通，以便于过滤后的水可以流入引流通道16中。
需要说明的是，由于通孔1701可能会流入一些细碎的颗粒残渣，因此，通过在滤斗17与第一阻挡件18之间设置储水腔20可以对这些颗粒残渣进行沉淀收集以实现二次过滤，当储水腔20中的水向上蔓延至过流通道21内即可流至引流通道16中，由此可有效提高过滤效果；此外，储水腔20的底部可以对牙签等细长物进行有效阻挡。因此，本申请实施例通过通孔1701及储水腔20实现了至少两级过滤，进一步地保证了该过滤装置的过滤效果，进而可以有效地将残渣聚集在粉碎装置的第一粉碎区域进行粉碎，并且提高了滚刀10的自清洁效果。
根据本申请的一个实施例，储水腔20的上部开口与滤斗17上的所有通孔1701相对应，以使储水腔20能够覆盖所有通孔1701，也即，所有通孔1701中流出的水均可以先经过储水腔20的沉淀过滤后，再流至引流通道16内，进一步提高过滤效果。
根据本申请的一个实施例，如图5和图17所示，第一阻挡件18设置于靠近滤斗17的一侧，且第一阻挡件18自滤斗17的底部朝向滤斗17的顶部延伸。在本申请实施例中，第一阻挡件18的底部设置于粉碎装置的机壳15顶部，以与滤斗17之间形成储水腔20，储水腔20一方面可以过滤水，另一方面储水腔20的底部可以阻挡牙签等细长物直接掉落至引流通道16中。
第二阻挡件19设置于第一阻挡件18背向滤斗17的一侧，第二阻挡件19的顶部与滤斗17的顶部相连，且第二阻挡件19朝向滤斗17的底部 延伸。
在另外一种实现方式中，粉碎组件3还包括过滤装置，过滤装置包括滤斗17，设置于第一腔室，滤斗17的侧壁设有与第一腔室连通的通孔1701。
可以理解的是，在这种实现方式中，滤斗17可以直接设置于第一腔室中，在滤斗17的侧壁设有与第一腔室连通的通孔1701，由于可能存在部分残渣会随水流进入第一腔室，影响刀具的自清洁效果和造成通道2堵塞，因此，本申请实施例通过设置滤斗17且滤斗17的侧壁设有通孔1701，可以对残渣进行过滤，防止残渣进入第一腔室中。
根据本申请的一个实施例，参见图17，过滤装置还包括阻挡组件，设置于滤斗17的外侧并与通孔1701对应，阻挡组件包括间隔设置的第一阻挡件18和第二阻挡件19，在垂直于通孔1701的轴向的平面内，第一阻挡件18的正投影与第二阻挡件19的正投影部分重叠，滤斗17的外侧与第一阻挡件18之间形成有储水腔20，第一阻挡件18与第二阻挡件19之间形成有与储水腔20相连通的过流通道21，过流通道21与第一腔室连通。
根据本申请的实施例，通过在滤斗17通孔1701的外侧设置第一阻挡件18及第二阻挡件19，并将第一阻挡件18及第二阻挡件19间隔设置且使得二者在垂直于通孔1701的轴向的平面内的正投影部分重叠，其中，通孔1701的轴向即如图16中所示的虚线的方向。当牙签等细长物流入通孔1701时，牙签等细长物会被第一阻挡件18和第二阻挡件19中的至少一个阻挡，或者牙签等细长物也可以被卡在第一阻挡件18与第二阻挡件19之间，这就使得牙签等细长物无法继续通过通孔1701。
这样一来，本申请实施例通过上述设置的阻挡组件可以挡住牙签等细长物，防止其经通孔1701流至滤斗17外侧的第一腔室中，避免后续通道2堵塞。
根据本申请的一个实施例，如图17所示，图中Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ表示牙签等细长物，图17示出了牙签等细长物的五种插入通孔1701的角度，无论从哪个角度插入通孔1701，均会被第一阻挡件18和第二阻挡件19阻挡，无法经通孔1701继续流出。其中，Ⅰ号牙签为竖直插入通孔1701，Ⅱ号、Ⅲ号、Ⅳ号和Ⅴ号牙签为倾斜插入通孔1701；当滤斗17的侧壁为竖直面时，Ⅰ号牙签无法插入通孔1701，只有倾斜方向的Ⅱ号、Ⅲ号、Ⅳ 号和Ⅴ号牙签可以插入通孔1701，但会被第一阻挡件18和第二阻挡件19阻挡，无法通过通孔1701；当滤斗17的侧壁为如图14和图15所示的倾斜面时，竖直方向的Ⅰ号牙签同样无法插入通孔1701，倾斜方向的Ⅱ号、Ⅲ号、Ⅳ号和Ⅴ号牙签可以插入通孔1701，但同样会被第一阻挡件18和第二阻挡件19阻挡，而无法通过通孔1701，阻挡组件的具体阻挡方式参见下述。
当牙签等细长物以如图17中Ⅱ号牙签所示的方向进入滤斗17下部的通孔1701时，牙签等细长物的端部会被第一阻挡件18挡住，即牙签等细长物被卡在通孔1701及第一阻挡件18之间，同时，由于第一阻挡件18与粉碎装置顶部的机壳15上形成有储水腔20，使得储水腔20的底部也会对牙签进行阻挡。因此，牙签等细长物无法继续通过滤斗17的通孔1701流至引流通道16中。
当牙签等细长物以如图17中Ⅲ号牙签和Ⅳ号牙签所示的方向进入滤斗17上部的通孔1701时，牙签等细长物的端部会被第二阻挡件19挡住，即牙签等细长物被卡在通孔1701及第二阻挡件19之间，无法通过滤斗17的通孔1701流至引流通道16中。
当牙签等细长物以如图17中Ⅴ号牙签所示的方向进入滤斗17上部的通孔1701时，牙签等细长物的端部会卡在第一阻挡件18及第二阻挡件19之间，无法通过滤斗17的通孔1701流至引流通道16中。因此，本申请实施例通过在滤斗17的外侧且引流通道16的上游设置上述阻挡组件，可以有效阻挡牙签等细长物从不同位置通过通孔1701。
根据本申请的一个实施例，餐具里面大部分是煮熟后的残渣，容易沉入水里积聚在粉碎装置中进行粉碎，由于牙签有浮力，会有部分牙签不容易积聚在粉碎装置前，会漂浮在残渣的上方，有可能从滤斗17的通孔1701流入引流通道16中，进而卡住第一抽吸件4和第二抽吸件，影响其工作。牙签由于受到水流的影响，一般是以Ⅱ号、Ⅲ号、Ⅳ号和Ⅴ号牙签的倾斜方式插入通孔1701，本申请实施例中，为了更好地实现上述的阻挡效果，使第二阻挡件19的高度H 2大于第一阻挡件18的高度H 1，具体的，第二阻挡件19的高度H 2与第一阻挡件18的高度H 1的比值的取值范围设置为2.6至3.2，例如，第一阻挡件18的高度H 1可以取20mm-23mm，第二阻 挡件19的高度H 2可以取60mm-63mm，这样可以最大限度的限制牙签等细长物流过通孔1701进入引流通道16，而且还可以使第一阻挡件18与滤斗17外侧形成的储水腔20与过流通道21及引流通道16相互连通，保证通过的水流量，进而保证自清洁效果。
根据本申请的一个实施例，如图17所示，第一阻挡件18与第二阻挡件19的间隔W 1的取值范围为15mm-16mm，这里主要考虑能通过的水量符合洗涤循环的水量要求，既可以防止牙签等细长物通过通孔1701，又能保证水的过流空间，进一步保证后续洗碗机的喷淋洗涤效率。
应当理解的是，在本申请实施例中，第一阻挡件18与通孔1701的间距以及第二阻挡件19与通孔1701的间距应小于牙签等细长物的长度，以便可以更好地对牙签等细长物进行阻挡。
根据本申请的一个实施例，如图14和图15所示，由滤斗17的顶部向滤斗17的底部，滤斗17的横截面积逐渐减小，进而使滤斗17的侧壁为倾斜面，便于将水渣混合物收集至粉碎装置的第一粉碎区域中，且可以使通孔1701流出的水更好地进入储水腔20中进行沉淀过滤，进一步提高过滤效果。
本申请滤斗17的具体形状不做特别限制，在一些实施例中，滤斗17的形状可以为圆台形或棱台形。
如图15和图16所示，滤斗17上部的通孔1701与下部的通孔1701之间设有台阶部22，通过设置台阶部22，也可以起到阻挡牙签等细长物的作用，如图17中竖直插入通孔1701的Ⅰ号牙签，直接插在台阶部22上，无法进入通孔1701。
根据本申请的一个实施例，如图13所示，滤斗17的底部出料口1703的长宽比的取值范围为1.1至1.3，例如，滤斗17的底部出料口1703的长度L为70mm-72mm，宽度W 2为59mm-62mm，通过设置滤斗17的底部出料口1703的大小，能有效保证水渣混合物落入粉碎装置的第一粉碎区域中。
根据本申请的一个实施例，如图13所示，滤斗17的通孔1701为多个并间隔分布，由滤斗17的顶部向底部的方向，相邻两个通孔1701之间的孔距F的取值范围为7mm-8mm，并且通孔1701的宽度与高度的比值的取 值范围为1.1至1.6，例如，通孔1701的宽度W 3为7mm-8mm，通孔1701的高度H 3为5mm-6mm。由于牙签被切削粉碎充分时，粉碎充分后尺寸是5mm以内，允许进入滤斗17的通孔1701，本申请通过对通孔1701的尺寸进行设置，可以有效防止未粉碎牙签进入，又可以适当允许粉碎充分后的牙签进入。
根据本申请的一个实施例，垂直于滤斗17高度方向的相邻两个通孔1701的中心孔间距为8mm-9mm，可以有效防止未粉碎牙签进入。
根据本申请的一个实施例，沿滤斗17高度方向，通孔1701至少设置一排。在本示例中，通孔1701设置为两排，以提高过滤效果。
根据本申请的一个实施例，多个通孔1701设置于滤斗17至少两个相对的侧壁，以提高回水和过滤效率。
根据本申请的一个实施例，如图16所示，第一阻挡件18和第二阻挡件19可以为挡板，沿滤斗17的高度方向遮挡所有通孔1701。
根据本申请的一个实施例，如图1和图23所示，本申请过滤系统还包括滤网支架23，安装于壳体1的顶部，滤网支架23设有与粉碎组件3对应的第一开口28，第一开口28与滤斗17的入口对应设置，便于水渣混合物流入，且滤网支架23设有与过滤组件对应的第二开口29，第二开口29处设有第二滤网24，此时，第一滤网5的上端也可以设置开口，水渣混合物中的部分待过滤水可以经第二滤网24过滤后直接进入回水腔7或者第一滤网5内，一方面可以提高回水腔7内的水量，进而防止第一抽吸件4出现空吸现象，保证正常工作；另一方面可以保证下述洗碗机的回水喷淋量，提高循环喷淋效率。
根据本申请的一个实施例，由滤网支架23的边缘向第一开口28的方向，滤网支架23朝向壳体1倾斜设置，即滤网支架23整体结构朝下凹陷，并以2°-5°的角度向第一开口28倾斜，这样水渣混合物就会顺着滤网支架23倾斜汇集到第一开口28进而进入粉碎组件3。本申请通过该设置，可以对水渣混合物进行引流，便于其快速进入粉碎组件3，提高了粉碎及过滤效率。
根据本申请的一个实施例，滤网支架23上设有喷臂接口25，喷臂接口25的上端连接有喷臂(图中未示出)，喷臂接口25的下端经回水管道 26与第一抽吸件4相连。第一抽吸件4将回水腔7内已过滤的水经出水管道8抽出并经回水管道26送至喷臂，可以将滤网支架23上的水渣混合物冲入第一开口28或者对下述洗碗机内的餐具进行循环喷淋，进而提高洗涤效率。
另一方面，本申请第二方面实施例的洗碗机，主要包括：内胆(图中未示出)、壳体1(也可以称为“水杯”)以及上述实施例的过滤系统，在内胆内的上部设有餐具支架，以放置餐具，在内胆内的底部设有过滤系统。
基于上述实施例，下面参考图24和图25描述本申请洗碗机过滤系统的工作原理，主要包括：洗涤过程和排渣过程。
洗涤过程：如图24中箭头所示，开启第一抽吸件4，残渣和待过滤的水经水杯的入料口流入第一腔室的滤斗17，然后进入滚刀10的第一粉碎区域并被粉碎，由于滚刀10的切割速度并没有那么快，因此，当待粉碎残渣过多时，会在滚刀10上方产生聚集，此时较轻的物体(主要是牙签等细长物)就会漂浮在滤斗17的通孔1701附近，进而流入滤斗17的通孔1701中然后被阻挡组件阻挡，并且部分水流也会往通孔1701流动；大体积的块状残渣无法进入通孔1701，而是在重力的作用下继续往滚刀10方向下沉，一部分细碎的颗粒残渣可能会流过通孔1701，然后进一步进入储水腔20沉淀过滤，经通孔1701过滤后的水经引流通道16对滚刀10进行冲刷后进入底部的通道2中，冲刷后的水及粉碎后的水渣混合物被第一抽吸件4吸入第二腔室内的第一滤网5进行再次过滤，同时开启清洁装置6对第一滤网5上的部分残渣进行刮除，便于过滤后的水经第一滤网5的出水区域进入回水腔7内，第一抽吸件4将回水腔7内的水经喷臂接口送至喷臂，实现对餐具的循环喷淋洗涤。因此，本申请过滤系统既能保证残渣的自动粉碎，同时又可以保证洗碗机中的水循环利用。
并且在洗涤过程中，部分待过滤的水还可以经第二滤网24流入回水腔7或第一滤网5内，保证回水量，进而保证洗碗机的喷淋效果。
排渣过程：如图25中箭头所示，洗涤完成后，关闭第一抽吸件4，开启第二抽吸件，将第一腔室和/或第二腔室内的残渣经底部的通道2吸出，最后排放至洗碗机外部。
因此，本申请实施例洗碗机的过滤系统可以有效分离水渣混合物，实 现残渣的自动化处理，无需人工对残渣进行处理，实现了洗碗机的免维护功能；并且过滤系统可以实现循环喷淋，保证回水量，节约用水，进而提高了用户的使用体验。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
