Description

一种洗衣机 技术领域
本发明属于洗衣机领域，具体地说，涉及一种洗涤水不在内外桶之间交叉流动的免清洗洗衣机，尤其是涉及一种可对无孔内桶中线屑进行过滤收集的洗衣机。
背景技术
现有技术中的洗衣机一般包括内桶和外桶，外桶内部安装内桶，外桶用于容纳洗涤水，内桶内放置衣物；内桶内部安装有波轮等洗涤结构，内桶和/或波轮在电机驱动下旋转，以产生洗涤水流对衣物进行洗涤。在洗涤过程中，内桶经其上所设的脱水孔与外桶相连接，令内桶和外桶内部都盛水，因此现有技术中的常规洗衣机存在如下三个问题：
第一，浪费水，在实际工作中只需要内桶中的水；
第二，细菌滋生，内桶和外桶连接处的水无法完全排出，也无法清洁，长期使用下去，会造成外桶细菌滋生，污染衣物；
第三，外桶的存在大大减少了洗衣机的容量，对于常规洗衣机而言，想要扩容只能增大洗衣机的整体结构，这样将会过多占据了用户的居住空间，对小户型用户极其不友好。
为了克服上述问题，申请人提出了一种无孔内桶的洗衣机，其将内桶设置为不具有脱水孔的密闭容器，使得洗涤水盛放在内桶中，令内桶同时具备了盛水和旋转洗涤的双重功能，避免了洗涤水在内外桶之间流动，对内外桶之间腔室造成无法清洁污染的问题。
但是，由于无孔内桶是密封的内桶，使得洗涤过程中衣物上脱落的线屑等会留存在洗涤水中，令洗衣机排水时线屑堆积在无孔内桶的排水口附近、造成排水口堵塞，进而影响洗衣机的正常排水。
另外，由于无孔内桶是密封的内桶，使得洗涤过程中洗涤水中裹夹的线屑很难排出；尤其是在最后的脱水阶段,由于排水水流较弱，离心后的水需要攀爬到内桶最顶部的排水口再流出,使得排水动力进一步削弱,导致大量线屑残留在内桶中，大大影响了洗衣机对衣物的洗涤效果。
同时，现有洗衣机的线屑过滤器不可能无限量的收集线屑,也不具备在洗衣机每次执行衣物处理时及时清洗的功能，容易产生洗衣机在线屑过滤器处于饱和状态下继续运行、线屑过滤器无法对桶内线屑进行及时和有效收集的问题。
有鉴于此特提出本发明。

如图1至5所示，本实施例中介绍了一种洗衣机，其包括：壳体2，壳体2内设有内桶1，内桶1轴线竖直设置；内桶1顶端开口设置构成内桶筒口101、底端密封设置构成内桶底103，内桶筒口101与内桶底103之间经内桶侧壁102相连；内桶1的至少中下部筒壁上不设通孔，以使得内桶1内部构成顶部开口设置的盛水容器。同时，洗衣机壳体2上端安装有可向外打开的门盖4，以在门盖4打开后自内桶筒口101向内桶1中投放衣物的目的。内桶1下部经内桶支撑件3安装于洗衣机壳体2内，所述的内桶支撑件3与内桶1同轴设置，内桶支撑件3经减震吊杆、或减震支脚与洗衣机壳体2相连接，以实现内桶支撑件3可震动得安装于洗衣机壳体2内的目的；同时，内桶底103中心与洗衣机驱动电机5的电机轴同轴设置，以驱动内桶1旋转，内桶1和驱动电机5均固定安装于内桶支撑件3上。优选的，内桶底103与驱动电机5分别设置与内桶支撑件3的上下两侧，驱动电机5与内桶支撑件3相固定连接，驱动电机5的电机轴经轴承穿过内桶支撑件3并与内桶底103同轴固定连接，且驱动电机5的电机轴可相对内桶支撑件3旋转，以实现内桶1和驱动电机5安装于内桶支撑件3上、并令内桶1可独自在驱动电机5作用下进行旋转对内部衣物进行洗涤的目的。
还有，内桶1中安装有可相对旋转的搅拌结构，搅拌结构可以为现有的任一装置，例如：波轮10、搅拌柱等等。从而，在驱动电机的作用下，驱动内桶1和/或搅拌结构旋转，使内桶中形成多样的水流、利用水流对内桶中衣物进行处理。同时，为了保证内桶旋转时的平稳性，在内桶1上设置有平衡环11，平衡环11优选的处于内桶筒口101处。
同时，通过将洗衣机进行洗涤时内桶形成盛水容器，使得洗涤过程中衣物只与盛水内桶中的洗涤水接触，避免了内外桶之间洗涤水交叉流动、内外桶之间洗涤水流入内桶中污染衣物情况的发生，大大提高了洗衣机的洗涤洁净度，避免了内外桶之间被洗涤水污染造成洗衣机清洗衣物不彻底情况的发生。
本发明实施例中为了将洗衣机内桶1中衣物脱离后水流进行外排，并实现洗衣机工作过程中内桶1密封盛水进行正常洗涤，进行如下设置：
本发明实施例中的洗衣机可以为现有技术中任一具备内桶1构成可转动盛水容器的洗衣机，内桶1为桶径自下向上逐渐增大的锥形，在内桶1顶部最大筒径的截面中设置至少一个排水口7，以在内桶1正常洗涤、漂洗过程中，洗涤水不会被甩动至排水口7处流出，令内 桶1直接构成供洗涤、漂洗水容纳的盛水桶，以利用内桶中盛放的洗涤、漂洗水对衣物进行洗涤、或漂洗；在内桶1执行脱水、排水过程中，内桶1转速高于设定值时，洗涤水受离心力驱动向上流动、而流向内桶1顶部设置的排水口7，顺利外排出内桶1，进而达到对无孔内桶洗衣机正常执行脱水程序的目的。本发明实施例中的洗衣机并不局限于附图中的结构，例如：还可以如图1所示，采用现有普通洗衣机，只需将洗衣机内桶1设置为至少中下部没有脱水孔、在洗衣机洗涤时形成盛水容器的洗衣机。
同时，为了保证内桶1中的密封性，可以在内桶1上设置可开闭内桶筒口101的内桶盖，以对应开闭内桶筒口101；此外，为了防止洗涤水自排水口7误排出，可以在内桶1上设置对应开闭排水口7的离心阀8，正常时离心阀8闭合排水口7；而在洗衣机执行脱水时，控制内桶转速达到设定值后，离心力驱动离心阀8的阀芯打开排水口7、实现顺畅排水的效果。
本发明实施例中，由于洗衣机的内桶1为盛水容器，在洗衣机洗涤过程中，衣物上被洗涤脱离的线屑会留存在洗涤水中，导致洗涤后衣物上回留存线屑的问题；为了解决上述问题，本发明中在洗衣机的可旋转盛水容器的内桶1上设有线屑过滤器6，内桶1中水流经线屑过滤器6过滤处理，线屑过滤器6对流经水中的线屑进行过滤，实现对洗衣机内桶中的线屑进行收集、可有效避免洗涤水中裹夹线屑导致洗涤后衣物上留存的问题。
本发明实施例中，线屑过滤器6可以为现有的任一可对洗涤水中线屑进行过滤收集的结构；本发明实施例中为了便于表述，将线屑过滤器6进行如下设置：如图3至图5所示，线屑过滤器6安装于内桶1内壁上，线屑过滤器6内部具有过滤腔60；线屑过滤器6上设有将过滤腔60与内桶1内部相连通的进水口71和出水口72，进水口71和出水口72处分别设有控制水流流向的单向阀；过滤腔60内、出水口72处、单向阀上的任一或组合处设有对流经水流中的线屑进行过滤的过滤结构73，用于将线屑截留至过滤腔60中。
本发明实施例中，如图1所示，内桶1上设有排污孔61，排污孔61连通线屑过滤器6的过滤腔60与内桶1外部的外桶31；优选的，外桶31的筒口处设有可开闭的外桶盖12，以防止水流外溅；
或者，如图2所示，内桶1上设有排污孔61，内桶1下方设有集水槽32，内桶侧壁102上设有向下竖直延伸的流道9，流道9的下端伸入集水槽32中，排污孔61连通线屑过滤器6的过滤腔60与流道9，用于将截留的线屑随洗衣机排水一起经排污孔61排至内桶1外的集水槽32。
本发明实施例中，线屑过滤器6内的过滤腔60中安装有控制排污孔61开闭的离心阀8； 在内桶转速达到设定值后，离心阀8的阀芯受离心力作用而打开排污孔61。
在洗衣机正常执行洗涤程序时，离心阀8闭合排污孔61，线屑过滤器6的过滤腔60仅与内桶1内部相连通，内桶1中洗涤水流经线屑过滤器6后、线屑被截留在过滤腔60内，使得线屑过滤器6实现了对内桶1中线屑进行收集的效果；在洗衣机执行脱水、排水程序时，内桶高速旋转，离心阀8受离心力驱动而打开排污孔61，线屑过滤器6的过滤腔60与内桶1内、外分别相连通，内桶1中洗涤水受离心力驱动而向上流动，流动过程中流经线屑过滤器6，部分洗涤水经过滤器6、排污孔61流出内桶，流出过程中对过滤腔60内收集的线屑一并冲洗、使线屑被冲出内桶1，达到对线屑过滤器6收集线屑冲出内桶1、对线屑过滤器6进行自动清理的效果。
本发明实施例中，通过在无孔内桶上设置线屑过滤器6，并在线屑过滤器6上设置与内桶1外部相连通的排污孔61、排污孔61处设置受内桶转速产生的离心力控制开闭的离心阀8结构，令线屑过滤器6收集的线屑，可在洗衣机执行脱水、或排水时，随排水水流一并冲出内桶、完成对线屑过滤器6进行自动清洗的效果。
如图1至图5所示，本发明实施例中，内桶1为轴线竖直设置、上端开口的桶状结构；线屑过滤器6设置于内桶侧壁102的中部，线屑过滤器6至少部分低于洗衣机内桶1的最高洗涤水位、至少部分高于洗衣机内桶1的最低洗涤水位，以保证洗涤水中的线屑可被线屑过滤器6进行有效收集、过滤。同时，本发明实施例中，内桶1的内桶侧壁102为上端径向尺寸大、下端径向尺寸小的锥形，以使得洗衣机脱水、排水时，内桶1中的洗涤水可受离心力驱动贴内桶侧壁102向上流动，流动时至少部分洗涤水流入线屑过滤器6的过滤腔60中，达到利用排水水流对线屑过滤器6进行自动清理的效果。
本发明实施例中，内桶侧壁102上排布有多个线屑过滤器6，各线屑过滤器6相对内桶1轴线对称间隔排布，进而提升洗衣机的过滤效果；同时，还能对内桶1中心进行调平处理，可有效防止内桶偏心旋转。
本发明实施例中，如图1所示，内桶1的顶端的内桶侧壁102上排布有多个排水口7，内桶1可旋转的套装于外桶31中，外桶31构成内桶支撑件3，各排水口7连通内桶1内部与内桶1外部的外桶31，使得自内桶1的排水口7流出的洗涤水可汇集至外桶31中，再经外桶31底部连通的排水管外排。优选的，为了防止洗涤水外溅，可以在外桶31上设置对应开闭外桶筒口的外桶盖12。
或者，如图2所示，内桶1的顶端排布有多个排水口7，内桶1下方设有集水槽32，内 桶侧壁102上设有向下竖直延伸的流道9，流道9上端与排水口7一一相对连通、流道9的下端均伸入集水槽32中，排水口7连通内桶1内部与内桶1外部的流道9，用于将受离心力带动而提升至内桶筒口101处的水经排水口7排至流道9、再经流道9导流后流入内桶1外部的集水槽32中。优选的，集水槽32与内桶1同轴设置，集水槽32的开口径向尺寸大于内桶1径向尺寸；进一步优选的，内桶1的至少下端部伸入集水槽32内，且内桶1外壁与集水槽32内壁之间相保留间隔，以保证内桶旋转、且可使得排水可全部流入集水槽32内。
如图3所示，本发明实施例中，离心阀8结构包括：排污孔61，设于内桶1上，贯通设置，以供水流穿过；离心阀8，安装于内桶1上、对应设于排污孔61处，离心阀8的阀芯对排污孔61进行封堵，并在内桶1转速达到设定值后离心阀8的阀芯受离心力作用而打开。优选的，离心阀8还包括一弹性件，弹性件夹持于阀芯与内桶1之间，以对阀芯提供复位作用力、而推动阀芯封堵排污孔61。上述的离心阀8可以为现有技术中任一可实现受离心力作用而打开孔的阀体结构。当然，本申请中的离心阀8还可以为现有的任意一种利用内桶旋转离心力驱动、而对应开闭排污孔61的结构；同时，本申请中，排污孔61处设置的阀并不局限于离心阀8，还可以为对排污孔61进行开闭操控的其他形式的阀，例如：电控阀、液压阀等等。
如图1至图3所示，本实施例中，所述离心阀8可以进行如下设置，内桶侧壁102上设有排污孔61，内桶侧壁102内侧安装有离心阀8。离心阀8包括安装于内桶1内侧的支架65，支架65上安装有相铰接的配重块62，排污孔61处设有可上下移动的阀塞柱64，阀塞柱64与配重块62相铰接，阀塞柱64与内桶侧壁102之间夹持有复位弹簧66，以在内桶1旋转离心力作用下带动配重块62向远离内桶1轴线方向移动，进而通过铰接处拉动阀塞柱64向内桶1轴线方向移动而打开排污孔61。
本发明实施例中，线屑过滤器6可以为现有技术中任意一种可对洗涤水中线屑进行收集的线屑过滤装置。
如图4和图5所示，本申请中的线屑过滤器6可以如下设置：线屑过滤器6包括外壳70，外壳70扣合安装于内桶侧壁102的内侧，外壳70与内桶1围成过滤腔60；线屑过滤器6的外壳70沿内桶1转动方向的相对两侧分别设置第一开口711和第二开口712，第一开口711和第二开口712处分别设置可绕轴旋转的阀片74，阀片74的转轴与内桶1轴线相平行，阀片74可受水流冲击向外壳70内部旋转打开开口、并受外壳70限位而无法转至外壳70外部，以实现内桶1绕轴旋转时水流冲击其中一个开口的阀片74向内旋转而打开对应、另一开口的 阀片74受外壳70限位而闭合对应开口，进而达到线屑过滤器6的两侧开口择一打开、择一闭合的效果；从而，使得第一开口711和/或第二开口712构成线屑过滤器6的可开闭的进水口71。外壳70朝向内桶1内部一侧和/或上侧、下侧设有出水口72，出水口72处设有对流出水流进行线屑过滤的过滤结构73，使得流经线屑过滤器6的过滤腔60的水流中的线屑被过滤结构73截留于过滤腔60中，以实现对内桶1中线屑的收集。
本发明实施例中，所述的过滤结构73并不局限于本发明附图中所示的过滤孔结构，还可以为过滤网、过滤栅格、过滤梳齿600等现有的任一或组合结构。同时，本发明实施例中，所述的过滤结构73是与外壳70一体设置的；但过滤结构73并不局限于此，还可以将过滤结构73设置为单独件，单独设置的过滤结构73安装于外壳70、或内桶1上，同样可实现对流经水流进行线屑过滤处理的效果。
衣物洗涤过程中，内桶1带动洗涤水沿顺时针方向或逆时针方向旋转，洗涤水冲开设置在侧壁的单向阀片74进入线屑过滤器6，经线屑过滤器6的前侧板、相对侧板上的过滤结构73过滤后从滤孔构成的出水口72排出，线屑存留在过滤腔60中从而完成内桶1中洗涤水的过滤。
阀片74可以仅仅设置在线屑过滤器6的一侧，即仅在线屑过滤器6的一侧设置进水口71。这种线屑过滤器只能在内桶1沿单向旋转时起到过滤线屑的作用。作为优选方案，如图4和图5所示，在线屑过滤器6的左右两侧均设置装有单向阀片74的进水口71能够起到双向的过滤效果，当内桶1沿顺时针方向或逆时针方向旋转时，洗涤水均能够进入线屑过滤器6，使过滤作用更全面。
实施例二
如图6至图12所示，本实施例中介绍了一种洗衣机，其包括：壳体2，壳体2内设有内桶1，内桶1轴线竖直设置；内桶1顶端开口设置构成内桶筒口101、底端密封设置构成内桶底103，内桶筒口101与内桶底103之间经内桶侧壁102相连；内桶1的至少中下部筒壁上不设通孔，以使得内桶1内部构成顶部开口设置的盛水容器。同时，洗衣机壳体2上端安装有可向外打开的门盖4，以在门盖4打开后自内桶筒口101向内桶1中投放衣物的目的。内桶1下部经内桶支撑件3安装于洗衣机壳体2内，所述的内桶支撑件3与内桶1同轴设置，内桶支撑件3经减震吊杆、或减震支脚与洗衣机壳体2相连接，以实现内桶支撑件3可震动得安装于洗衣机壳体2内的目的；同时，内桶底103中心与洗衣机驱动电机5的电机轴同轴设置，以驱动内桶1旋转，内桶1和驱动电机5均固定安装于内桶支撑件3上。优选的，内 桶底103与驱动电机5分别设置与内桶支撑件3的上下两侧，驱动电机5与内桶支撑件3相固定连接，驱动电机5的电机轴经轴承穿过内桶支撑件3并与内桶底103同轴固定连接，且驱动电机5的电机轴可相对内桶支撑件3旋转，以实现内桶1和驱动电机5安装于内桶支撑件3上、并令内桶1可独自在驱动电机5作用下进行旋转对内部衣物进行洗涤的目的。
还有，内桶1中安装有可相对旋转的搅拌结构，搅拌结构可以为现有的任一装置，例如：波轮10、搅拌柱等等。从而，在驱动电机5的作用下，驱动内桶1和/或搅拌结构旋转，使内桶中形成多样的水流、利用水流对内桶中衣物进行处理。同时，为了保证内桶旋转时的平稳性，在内桶1上设置有平衡环11，平衡环11优选的处于内桶筒口101处。
同时，通过将洗衣机进行洗涤时内桶形成盛水容器，使得洗涤过程中衣物只与盛水内桶中的洗涤水接触，避免了内外桶之间洗涤水交叉流动、内外桶之间洗涤水流入内桶中污染衣物情况的发生，大大提高了洗衣机的洗涤洁净度，避免了内外桶之间被洗涤水污染造成洗衣机清洗衣物不彻底情况的发生。
本发明实施例中为了将洗衣机内桶1中衣物脱离后水流进行外排，并实现洗衣机工作过程中内桶1密封盛水进行正常洗涤，进行如下设置：
本发明实施例中的洗衣机可以为现有技术中任一具备内桶1构成可转动盛水容器的洗衣机，内桶1为桶径自下向上逐渐增大的锥形，在内桶1顶部最大筒径的截面中设置至少一个排水口7，以在内桶1正常洗涤、漂洗过程中，洗涤水不会被甩动至排水口7处流出，令内桶1直接构成供洗涤、漂洗水容纳的盛水桶，以利用内桶中盛放的洗涤、漂洗水对衣物进行洗涤、或漂洗；在内桶1执行脱水、排水过程中，内桶1转速高于设定值时，洗涤水受离心力驱动向上流动、而流向内桶1顶部设置的排水口7，顺利外排出内桶1，进而达到对无孔内桶洗衣机正常执行脱水程序的目的。本发明实施例中的洗衣机并不局限于附图中的结构，例如：还可以如图6所示，采用现有普通洗衣机，只需将洗衣机内桶1设置为至少中下部没有脱水孔、在洗衣机洗涤时形成盛水容器的洗衣机。
同时，为了保证内桶1中的密封性，可以在内桶1上设置可开闭内桶筒口101的内桶盖，以对应开闭内桶筒口101；此外，为了防止洗涤水自排水口7误排出，可以在内桶1上设置对应开闭排水口7的离心阀8，正常时离心阀8闭合排水口7；而在洗衣机执行脱水时，控制内桶转速达到设定值后，离心力驱动离心阀8的阀芯打开排水口7、实现顺畅排水的效果(未在附图中注明)。
如图7至图12所示，本发明实施例中，由于洗衣机的内桶1为盛水容器，在洗衣机洗涤 过程中，衣物上被洗涤脱离的线屑会留存在洗涤水中，导致洗衣机排水时线屑会随排水一并流向排水口7、线屑在排水口7处堆积而导致堵塞的问题；为了解决上述问题，本发明中在洗衣机的可旋转盛水容器的内桶1上设有线屑过滤器6，内桶1流向排水口7的排水水流中裹夹的线屑经线屑过滤器6进行过滤拦截，实现对洗衣机内桶外排水中的线屑进行过滤拦截、有效避免洗涤水中裹夹线屑外排是堵塞无孔内桶的排水口7的问题。
本发明实施例中，线屑过滤器6可以为现有的任一可对洗涤水中线屑进行过滤收集的结构；例如：线屑过滤器6为覆盖排水口7的栅格结构、网孔结构、梳齿结构中的一种或组合，栅格结构的镂空删隔孔、网孔结构的镂空孔、梳齿结构的镂空部等等构成线屑过滤器6的镂空过滤间隙，镂空间隙供排水水流流过、排水水流中的线屑被过滤拦截于线屑过滤器6上。
本发明实施例中，线屑过滤器6可以与内桶1为一体件；或者，线屑过滤器6也可以为固定安装于内桶1上的独立件；优选的，内桶1的顶部内桶筒口101处安装有一圈环形的平衡环11，线屑过滤器6与平衡环11相固定连接、或一体成型，以实现线屑过滤器6与内桶1固定安装、一并旋转的效果。
如图6至图12所示，本发明实施例中，线屑过滤器6为设于内桶侧壁102内周的、覆盖排水口7的一圈环形结构，环形线屑过滤器6的上下两侧分别与内桶1内壁相接，线屑过滤器6与内桶1内壁共同围成一过水空间602，过水空间602经排水口7与内桶1外部相连通，过水空间602经线屑过滤器6上的过滤间隙与内桶1内部相连通。
当然，本发明实施例中，还可以将环形线屑过滤器6的上侧、和/或下侧经其他部件与内桶1内壁间接相接，以围成过水空间602；例如：在内桶筒口101处安装平衡环11，环形线屑过滤器6的下侧与内桶1内壁相接，环形线屑过滤器6的上侧与平衡环11下侧相接，以使得环形线屑过滤器6、平衡环11和内桶1内壁共同围成(未在附图中注明)。
通过将环形过滤装置的上下两侧分别与内桶内壁相连，以形成一环形过水空间602，令内桶的排水水流全部需经线屑过滤器6过滤后再流入过水空间602、经内桶上的排水口7外排，进而保证了对洗衣机排水水流全部进行线屑过滤处理、防止无孔内桶的排水口7被线屑堵塞的显著技术进步。
本发明实施例中，内桶1为轴线竖直设置、上端开口的桶状结构，内桶侧壁102为上端径向尺寸大、下端径向尺寸小的锥形；内桶侧壁102的顶部设有至少一个排水口7，环形线屑过滤器6设于内桶1顶部的内周侧，各排水口7分别与环形线屑过滤器6和内桶1内壁围成的过水空间602相连通，以使得受内桶旋转离心力作用而上升至顶部的排水水流，经线屑 过滤器6过滤后再经过水空间602、排水口7外排。
如图6至图12所示，本发明实施例中，线屑过滤器6包括沿内桶周向间隔排布的多个过滤梳齿600，相邻过滤梳齿600之间的梳齿间隙d构成的供水流通过的过滤间隙，梳齿间隙d小于排水口7的孔径D；优选的，过滤梳齿600为片状结构，片状过滤梳齿600与内桶1径向截面之间夹角为a，a大于等于0、小于90；上述的截面为片状过滤梳齿600的外周侧、与内桶相连处所处的内桶截面，夹角a为上述截面和片状过滤梳齿600所处截面之间的夹角。
本发明实施例中，环形线屑过滤器6为自下向上逐渐收窄的锥状，线屑过滤器6拦截下来的线屑受排水水流冲击作用而向上移动，令线屑过滤器6上挂设的线屑避让开锥形线屑过滤器6的下部、避免了线屑在锥形线屑过滤器6下部堆积的现象，令较小排水水流依然可穿过线屑过滤器6的过滤间隙，进而实现洗衣机的顺畅排水。
如图7至图9所示，本发明实施例中，环形线屑过滤器6可以分为筒状上部的收集部605和锥状下部的过滤部604，所述收集部605为与内桶1同轴的桶状。优选的，为了提升收集部605的线屑收集效率，在收集部605上设置向过水空间602侧凹陷的、朝向内桶径向侧敞口设置的收集槽606。
如图10至图12所示，本发明实施例中，环形线屑过滤器6可以分为锥度不同的上部收集部605和下部过滤部604，锥形收集部605的锥度a2大于锥形过滤部604的锥度a1。
通过将环形线屑过滤器6分为不同锥度的上下两部分，以在两部分连接处形成拐角，使得线屑在水流冲击及内桶旋转离心力作用下，可以越过锥角为a1的过滤部斜面，并在拐角处收集；同时，由于锥角为a2的收集部605具有一定延伸长度，令收集的线屑被截留于该处；还有，由于过滤的线屑被收集于拐角处，令线屑过滤器6的过滤部604处不留存、或极少留存线屑，令排水水流可顺畅进入线屑过滤器6和内桶围成的过水空间602中，不阻挡洗衣机的排水水流流动。
优选的，如图7至图12所示，本发明实施例中，为了进一步提升线屑过滤器6的过滤效率，在线屑过滤器6的过滤梳齿600上设置向过水空间602内部凹陷、朝向内桶内部敞口设置的收集槽606；所述的收集槽606设置于过滤梳齿600的收集部605上，以使得受排水水流冲击的线屑被挂设于收集槽606处、防止了线屑在过滤部604处的堆积。
本发明实施例中，各过滤梳齿600经至少一圈固定圈相连；优选的，各过滤梳齿600与固定圈一体设置；进一步优选的，如图7至图12所示，各过滤梳齿600的顶部经一圈挡水板 601相连，挡水板601构成固定圈，且挡水板601和各过滤梳齿600为一体件。从而，使得由多个过滤梳齿600构成的线屑过滤器6形成一个环状的整体结构，保证了线屑过滤器6的整体性、方便了其安装。
本发明实施例中，各过滤梳齿600的下端与内桶1内壁相连、上端经挡水板601与内桶1内壁相连，以使得由过滤梳齿600构成的线屑过滤器6的上下两端分别与内桶1相连，围成供排水水流流经的过水空间602，使得受离心力作用而贴合内桶1内壁向上流动的排水水流全部经线屑过滤器6过滤后、流经过水空间602后再经排水口7外排。同时，排水水流受挡水板601阻挡，避免了洗衣机排水水流自上部流出过水空间602、甚至溅出内桶筒口101情况的发生。
本发明实施例中，挡水板601为水平设置、沿内桶1径向延伸的环形，环形挡水板601的内周与各过滤梳齿600的顶端相连、外周与内桶1内周相连，以使得环形过水空间602的上方全部被挡水板601遮挡，有效防止了流入过水空间602中的排水水流自上部溢流出、甚至溅射出内桶情况的发生，进而有效保证了洗衣机排水水流的顺畅性。
本发明实施例中，如图6所示，内桶1的顶端的内桶侧壁102上排布有多个排水口7，内桶1可旋转的套装于外桶31中，外桶31构成内桶支撑件3，各排水口7连通内桶1内部与内桶1外部的外桶31，使得自内桶1的排水口7流出的洗涤水可汇集至外桶31中，再经外桶31底部连通的排水管外排。优选的，为了防止洗涤水外溅，可以在外桶31上设置对应开闭外桶筒口的外桶盖12。
或者，内桶1的顶端排布有多个排水口7，内桶1下方设有集水槽32，内桶侧壁102上设有向下竖直延伸的流道9，流道9上端与排水口7一一相对连通、流道9的下端均伸入集水槽32中，排水口7连通内桶1内部与内桶1外部的流道9，用于将受离心力带动而提升至内桶筒口101处的水经排水口7排至流道9、再经流道9导流后流入内桶1外部的集水槽32中。优选的，集水槽32与内桶1同轴设置，集水槽32的开口径向尺寸大于内桶1径向尺寸；进一步优选的，内桶1的至少下端部伸入集水槽32内，且内桶1外壁与集水槽32内壁之间相保留间隔，以保证内桶旋转、且可使得排水可全部流入集水槽32内(未在附图中注明)。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所 作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
