Description

一种洗衣机线屑过滤装置及洗衣机及线屑过滤方法 技术领域
本发明属于洗衣机技术领域,具体涉及一种洗衣机线屑过滤装置及一种装有上述线屑过滤装置的洗衣机,还涉及一种洗衣机线屑过滤方法。
背景技术
洗衣机洗涤衣物时产生线屑,为防止线屑粘到衣物上,一般来说都在洗衣机内桶壁上设置线屑过滤装置,收集线屑以达到清洁衣物的目的。这样,在洗完衣物后,需要拆下线屑过滤器进行清理,避免线屑过滤装置堵塞。
现有中国专利申请号为02268690.8的实用新型专利,该实用新型公开了一种洗衣机盒式线屑过滤器,由U型的过滤器前、过滤器后、过滤网、逆止阀组成,过滤网附在过滤器前上,逆止阀安装在过滤器前的底端。过滤器前U型腔内两侧有轨道,过滤器后的立侧壁能沿此轨道在过滤器前中推拉,从而扣合或打开盒式线屑过滤器。过滤器前、后侧壁上有相互对应的定位筋条,卡合后可防止两者因松动而脱开。起到收集线屑、洁净衣物的作用,并且抽拉式的结构拆装方便。
而现有的上述线屑过滤装置,一般设置于内桶内壁上,线屑过滤装置随内桶一起旋转,洗涤水流不断穿过线屑过滤装置,以实现对洗衣机洗涤水中裹夹的线屑进行过滤和收集的目的。
但是,上述结构的线屑过滤装置由于是安装于内桶壁上,因此在装配洗衣机时需将线屑过滤装置安装于内桶上,增加了生产过程中装配的繁琐度、降低了生产效率;同时,由于线屑过滤装置是凸出内桶壁表面设置,令内桶旋转过程中线屑过滤装置会对内桶中的洗涤衣物产生磨损;还有,由于上述结构的线屑过滤装置是将过滤后的线屑收集至收纳袋或收纳盒中,在洗衣机正常使用一定时间后,还需要用户对收集的线屑进行手动清理。
鉴于上述技术缺陷,特提出本申请。
发明内容
本发明的目的在于为了克服现有技术存在的上述缺陷,提供一种洗衣机线屑过滤装置,以实现对洗涤水中线屑进行自动收集、并对收集线屑进行自动清理的目的;同时,提供一种设于内桶底的线屑过滤装置,以实现将洗衣机内桶桶壁光滑设置、降低衣物磨损的目的。
为了解决所述的技术问题,达到所述的技术效果,本发明采用的技术方案的基本设计思路为:

进一步,洗衣机内桶侧壁光滑设置,由于将线屑过滤装置设置于内桶底,使得内桶侧壁上不再设置其他结构,令整个内桶侧壁由一光滑面构成,进而减少了洗衣机洗涤衣物与内桶壁之间的摩擦、降低了衣物的磨损。
本发明的还一目的在于提供一种洗衣机线屑过滤方法,洗衣机内桶中的洗涤水自内桶侧壁上所设脱水孔流至内外桶之间,再从内桶底部回流到内桶中,其特征在于,所述洗衣机在洗涤水自内桶底部回流至内桶时通过线屑过滤装置进行线屑过滤并收集;在洗衣机排水时,利用排水水流清除收集的线屑并将线屑随排水水流排出洗衣机。

如图1至图6所示,本发明实施例中介绍了一种洗衣机线屑过滤装置,线屑过滤装置5安装于内桶底部,该装置为洗衣机执行排水时利用水流清除线屑的自清洁过滤装置。
本发明实施例中还提供一种洗衣机的线屑过滤方法,洗衣机内桶2中的洗涤水自内桶侧壁20上所设脱水孔流至内外桶之间,再沿外桶侧壁11向下流动至内外桶底之间,后经内桶底部所设水路通道6回流入内桶2中,对自内桶底部的水路通道6回流至内桶2的洗涤水进行线屑过滤;在洗衣机排水时,利用排水水流清除收集的线屑并将线屑随排水水流排出洗衣机。
通过上述设置,使得洗涤水中裹夹的线屑被内桶底所设的线屑过滤装置进行过滤,并利用自内桶底水路通道流出的排水水流对收集的线屑冲洗清除随水流排至洗衣机外部,实现了对洗涤水中线屑进行自动收集和清理的目的。
实施例一
如图1至图6所示,本实施例中介绍了一种洗衣机线屑过滤装置5,线屑过滤装置5安装于内桶底21,该装置为洗衣机执行排水时利用水流清除线屑的自清洁过滤装置。
本实施例中,洗衣机的内桶底部设有水路通道6,水路通道6将内桶2内外两侧相连通;即,水路通道6将内桶2内部、和内外桶之间相连通,使得内外桶之间的洗涤水可经水路通道6流入内桶中、或使内桶中的洗涤水经水路通道6流入内外桶之间。水路通道6的具体结构依据不同洗衣机型号而定,水路通道6可以仅设置于内桶底21、也可仅设置于桶底法兰4、还可以依次穿过内桶底21和桶底法兰4。
本实施例中,所述的线屑过滤装置5包括安装于内桶底部上所设水路通道6处的滤网54,滤网54对自内桶底21与外桶底11之间的、经内桶底部所设水路通道6流入内桶2的洗涤水进行过滤,以使得流经滤网54的洗涤水中所裹夹的线屑被滤网54拦截,并将拦截的线屑留存在内桶底21与外桶底11之间,令流入回流入内桶2中的洗涤水中不含有、或少量含有线 屑,进而实现对洗涤水中线屑进行过滤去除、降低洗涤水中线屑与内桶中衣物接触的几率。
如图2和图3所示,本实施例中,线屑过滤装置5包括呈盘状的、水平设置的框架50,框架50的中心部与内桶底部固定连接;框架50的外周部铺设有滤网54,滤网54安装于内桶底部上所设的至少部分水路通道6。通过上述设置,使得滤网经框架安装于内桶底上;并将框架与内桶底同轴设置,以使得线屑过滤装置至少对自内桶底中部水路通道流入内桶的水流进行过滤;同时,由于内桶旋转过程中的搅动作用,使得内外桶之间的水流向内外桶底中心处,使得线屑过滤装置处流经的水流量较大,进而提高了线屑过滤效率。
本实施例中,还可以将滤网与框架设置为一体件、或不设框架仅设置滤网;线屑过滤装置5为盘状结构,盘状结构线屑过滤装置5的中部与内桶底部固定,盘状结构线屑过滤装置5与内桶底部之间设有一定间隙,沿盘状结构线屑过滤装置5的径向自中心向外周间隙逐渐增大,以使得线屑过滤装置5与内桶底部之间形成高度方向上逐渐变化的间隙,令内桶底部下部的洗涤水自线屑过滤装置5外周流入间隙、并经水路通道流入内桶中。
同时,如图7所示,在洗衣机排水时,内桶中洗涤水经过内桶底部所设水路通道6后,沿不同的第一排水水路和第二排水水路进入内外桶之间:
第一排水水路为自水路通道经过线屑过滤装置与内桶底部之间的间隙流至内外桶之间的水流,该水流对滤网上表面附着的以及间隙中存留的线屑进行冲洗,最后通过外桶所设排水口排出;
第二排水水路为自水路通道穿过过滤装置流至内外桶之间的水流,该水流对线屑过滤装置内部进行冲洗,将线屑过滤装置内部的线屑清除,最后通过外桶所设排水口排出。
还有,在排水时,内桶洗涤水中线屑随水流自内桶底所设水路通道流至内外桶底之间,并沿第一排水水路随洗涤水一起自排水口排出,实现了对内桶中残留线屑进行冲洗、并对线屑过滤装置进行自动清洁的目的。
本实施例中,内桶底部的水路通道6与线屑过滤装置5和内桶底部之间的间隙相连通,使流入间隙中的洗涤水自水路通道流入内桶中;进一步优选的,线屑过滤装置5中心处为与内桶底部与桶底连接的固定安装部,线屑过滤装置的外周处为自中心向外周逐渐向下倾斜的倾斜式滤网安装部,滤网安装部的上表面铺设有滤网、或滤网与滤网安装部一体设置,滤网与内桶底之间设有自内向外逐渐增大的间隙。
实施例二
如图1至图3所示,本实施例中介绍了一种洗衣机线屑过滤装置5,内桶底21的中心处设有桶底法兰4,所述线屑过滤装置5固定安装于桶底法兰4下部。
如图2和图3所示,本实施例中,所述线屑过滤装置5包括呈盘状的、水平设置的框架50,框架50的中心处为与桶底法兰4同轴固定的安装部51,框架50的外周为供滤网铺设的滤网安装部52。所述安装部51为套装于电机轴外部的圆环状,圆环状安装部51与桶底法兰4之间连接固定。圆环状安装部51的外周设有沿径向向外延伸的、多条支撑筋,各支撑筋的端部经连接筋相连接,以构成框架外周设置的滤网安装部52;优选的,各支撑筋的长度相等设置,以使得各连接筋围成的框架外周为圆形。所述滤网安装部52的上表面铺设有滤网54,以对流经水流中裹夹的线屑进行过滤。
本实施例中,线屑过滤装置5的框架50的外周处为自中心向外周逐渐向下倾斜的倾斜式滤网安装部52,滤网安装部52包括沿框架径向和/或周向间隔设置的多段支撑筋,各支撑筋构成栅格状结构,滤网安装部52的上表面铺设有滤网54,以使得内外桶底11之间的洗涤水自支撑筋之间的空隙穿过滤网54进行过滤后、再经内桶底21所设水路通道6流入内桶2,使得洗涤水中裹夹的线屑被滤网截留。
为了提高滤网的过滤效率,本实施例中,将桶底法兰4设置为中部向上凸出的、外周逐渐向下倾斜的槽状结构;所述线屑过滤装置5设置于槽状结构内,并将线屑过滤装置5上所设滤网54设置为自内向外逐渐向下倾斜的倾斜式,以便于滤网54过滤的线屑留存于滤网54内部,提高截留的线屑在内桶底21的集和度、便于排水水流的冲洗。
本实施例中,线屑过滤装置5的框架50夹持安装于桶底法兰4与外桶底11之间,框架50的安装部51分别与桶底法兰4和外桶底11上侧面相贴合接触,以使得线屑过滤装置5固定安装于洗衣机上;同时,框架50的滤网安装部52与外桶底11之间设置一定间距,以保证内外桶之间的水流可流入滤网内部,提高线屑过滤效率。
为了提高内桶底水路通道处的水流顺畅性、线屑过滤的效率,将滤网安装部52与桶底法兰4之间设置一定间隙设置,以使内外桶底11之间的洗涤水经间隙流入水路通道6,并使流经的洗涤水中裹夹的线屑被截留于滤网54上表面。优选的,所述滤网安装部52设置为自内向外逐渐向下倾斜的倾斜式结构,倾斜式滤网安装部52的顶部与桶底法兰4相对应贴合接触,倾斜式滤网安装部52自顶部至底部距桶底法兰4之间的间隙距离逐渐增大,以保证水流流入间隙内的顺畅性,并改变水流在间隙内的流速和流向,使得间隙处的线屑过滤效率得到显著提高。
为了减少滤网表面附着线屑、提高线屑被排水水流冲洗的效率,将滤网安装部52上铺设的滤网54设置为张紧状态、或将滤网54直接设置为由不会产生变形的刚性材质构成;优选的,将滤网54设为金属材质构成的、表面光滑的滤网54,使滤网54铺设于框架50的滤网安装部52上侧后,形成光滑的上侧面,以减少滤网表面线屑的存留。
本实施例中,桶底法兰4上设有连通内桶底部内外两侧的水路通道6,滤网54安装于桶底法兰4上所设水路通道6处。优选的,桶底法兰4的中部为与内桶轴7上端所设法兰盘8相固定的固定部,桶底法兰4的外周部设有多个水路通道6,水路通道的两端分别与内桶内部和内外桶之间相连通,各水路通道6相对桶底法兰4中心对称排布。所述线屑过滤装置5的框架50与桶底法兰4同轴设置,且滤网安装部52的内周径小于两个相对水路通道6之间的最小距离、滤网安装部52的外周经大于两个相对水路通道6之间的最大距离,使得各水路通道6的竖直下部均设有滤网54,以进一步提高线屑过滤效率。
上述方式适用于,内桶底部中心只设有桶底法兰4,因此只需在桶底法兰4上设置水路通道6,就可将内桶底部内外两侧相连通;还有,当内桶底部中心由桶底法兰4和内桶底21拼叠构成时,需要将水路通道6依次穿过桶底法兰4和内桶底21,使水路通道6的两端分别与内桶内部和内外桶之间相连通,同样可实现将内桶底部内外两侧相连通的目的。
如图2所示,本实施例中,框架50的安装部51上侧面设有向上凸出的多个卡爪53,各卡爪53分别与桶底法兰4相扣合固定连接,使框架50固定安装于桶底法兰4下侧,实现了线屑过滤装置5固定安装于内桶底21的目的。
实施例三
如图4所示,本实施例介绍了一种洗衣机线屑过滤装置5,与上述实施例二的区别在于:洗衣机的驱动电机经减速离合器与内桶轴7相连接,内桶轴7的上端伸入外桶1内部,内桶轴7与内桶2同轴设置,内桶轴7的伸入端设有与桶底法兰4下侧相连接的法兰盘8,线屑过滤装置5固定安装于法兰盘8上。
通过将线屑过滤装置5与内桶轴上端部相固定连接,使得线屑过滤装置5实现了与内桶之间的固定安装,令线屑过滤装置5可随内桶共同旋转,同样可实现对内外桶底11之间的洗涤水进行过滤的目的。
实施例四
如图5所示,本实施例介绍了一种洗衣机线屑过滤装置5,与上述实施例二的区别在于: 线屑过滤装置5安装于内桶底21上表面与波轮3之间,内外桶底11之间的洗涤水自内桶底部所设水路通道6流入内桶2后被线屑过滤装置5进行过滤,以实现对洗涤水中线屑过滤去除、并将线屑拦截于内外桶底11之间的目的。
实施例五
如图6所示,本实施例介绍了一种洗衣机线屑过滤装置5,与上述实施例二的区别在于:线屑过滤装置5安装于内桶底21下表面与桶底法兰4之间,内外桶底11之间的洗涤水流入内桶底部所设水路通道6之前被线屑过滤装置5进行过滤,以实现对洗涤水中线屑过滤去除、并将线屑拦截于内外桶底11之间的目的。
本实施例中,所述线屑过滤装置5的上、下两侧分别与内桶底21下表面与桶底法兰4相贴合接触,以使线屑过滤装置5被夹持安装于内桶底21上,实现了线屑过滤装置5在洗衣机上的固定安装。
本实施例中,可以将线屑过滤装置5设置为水平设置的圆环结构,以便于线屑过滤装置5被夹持于内桶底21与桶底法兰4之间,令线屑过滤装置的安装更为可靠;同时,降低了线屑过滤装置的高度。当然,还可以将线屑过滤装置5设置为倾斜式,以使得线屑过滤装置5与内桶底部之间相距一定间隙,以保证内桶底部所设水路通道的水流畅通性。
实施例六
本实施例中介绍了一种洗衣机,其包括外桶1,外桶1内部套装的内桶2,内桶2内部还可以安装有对衣物进行搅动的洗衣结构。所述洗衣结构可以为现有技术中的波轮3、搅拌柱等;为了便于表述,本实施例中以波轮3代替洗衣结构,但本实施例并不局限与采用波轮3做为洗衣机结构的技术方案。
本实施例中,洗衣机的内桶底21安装有上述实施例一至五任一所述线屑过滤装置5,以在洗涤过程中对洗涤水中裹夹的线屑进行过滤,并在洗衣机排水时,将截留在内外桶底之间的线屑随排水水流冲出;同时,在排水过程中,内桶2中水流自内桶底部所设水路通道6流出,并对线屑过滤装置5的滤网54进行冲洗,将滤网54上附着的线屑进行清理,进而实现对洗衣机内部线屑进行过滤收集、并对线屑过滤装置5进行自动清洁的目的。
实施例七
本实施例介绍了一种洗衣机的线屑过滤方法,洗衣机内桶中的洗涤水自内桶侧壁上所设脱水孔流至内外桶之间,在洗涤水经内桶底部回流到内桶过程中实现对洗涤水中的线屑过滤 并收集;在洗衣机排水时,利用排水水流清除收集的线屑并将线屑随排水水流排出洗衣机。
本实施例中,内外桶之间的洗涤水流从内桶底部回流入内桶时,洗涤水中的线屑被过滤。优选的,洗涤水中的线屑被内桶底下部所设倾斜式滤网截留,并将线屑留存在倾斜式滤网内部;同时,倾斜式滤网与内桶底之间设置一定间隙,令部分水流自间隙流过,并使流过水流中夹持的线屑被吸附于滤网上,实现对水流中线屑的过滤收集。
本实施例中,洗衣机排水时,内桶中的洗涤水自内桶底部所设水路通道流出、并自外桶底所设排水口外排;滤网上、或留存于滤网内部的线屑受经过滤装置流出的洗涤水水流冲洗而清除并随洗涤水一起自排水口排出。
本实施例中,为了提高内桶底部水路通道处的水流畅通性,可以将内桶底部所设滤网与内桶底部之间设有一定间隙,内外桶底之间洗涤水自间隙流入内桶底部水路通道,流经洗涤水中的线屑被截留至滤网上部、滤网与桶底法兰之间的间隙处。在洗衣机排水时,自内桶底部水路通道流出的排水水流冲向滤网,对滤网上表面附着的线屑进行冲刷,使得滤网与内桶底部之间间隙处留存的线屑被排水水流冲至洗衣机外部,同样可实现对间隙处留存线屑进行自动冲洗的目的。
本实施例中,洗衣机控制方法的具体步骤如下:
S1、洗衣机开始执行洗涤程序;
S2、随内桶旋转,内桶中洗涤水自内桶桶壁所设水路通道流出、并流入内外桶之间,随内桶旋转力,洗涤水流动至内外桶底之间的间隙中;
S3、洗涤水流经内桶底部所设线屑过滤装置,洗涤水中裹夹的线屑被线屑过滤装置上所设滤网过滤并拦截,拦截的线屑留存于内外桶底之间;
S4、去除线屑的洗涤水自内桶底所设水路通道回流入内桶中,以形成水流循环;
S5、洗涤程序结束后,执行排水程序;
S6、内桶中洗涤水自内桶底部所设水路通道流出,流出的水流流向内桶底部所述线屑过滤装置,对线屑过滤装置的滤网上所附着线屑进行冲洗;
S7、自线屑过滤装置的滤网上被冲洗下的线屑随排水水流通过外桶排水口排出洗衣机。
在上述步骤S5至S7中,洗衣机排水时,内桶中的洗涤水自内桶底所设水路通道流出、并自外桶底所设排水口外排,线屑过滤装置内部的线屑受经过滤装置流出的洗涤水水流冲洗 而清除并随洗涤水一起通过排水口排出;同时,在排水时,内桶洗涤水中线屑随水流自内桶底部所设水路通道流至内外桶底之间,并随洗涤水一起通过排水口排出
同时,如图7所示,在洗衣机排水时,
内桶中洗涤水经过内桶底部所设水路通道6后,沿不同的第一排水水路和第二排水水路进入内外桶之间:
第一排水水路为自水路通道经过线屑过滤装置与内桶底部之间的间隙流至内外桶之间的水流,该水流对滤网上表面附着的以及间隙中存留的线屑进行冲洗,最后通过外桶所设排水口排出;
第二排水水路为自水路通道穿过过滤装置流至内外桶之间的水流,该水流对线屑过滤装置内部进行冲洗,将线屑过滤装置内部的线屑清除,最后通过外桶所设排水口排出。
同时,在排水时,内桶洗涤水中线屑随水流自内桶底所设水路通道流至内外桶底之间,并沿第一排水水路随洗涤水一起自排水口排出,实现了对内桶中残留线屑进行冲洗、并对线屑过滤装置进行自动清洁的目的。
通过上述方法,使得洗衣机洗涤水中裹夹的线屑被内桶底所设线屑过滤装置进行过滤收集,同时利用排水水流对收集的线屑进行自动冲洗清除,实现了对线屑进行自动清理的目的;还有,内桶中的线屑和泥沙等污物,尤其是内桶底与波轮之间缝隙中的污物,会在洗衣机排水时,随水流自内桶底所设水路通道流至内外桶之间、并随排水水流自外桶排水口一同流出。
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。
