Description

一种过滤系统、过滤模块、洗涤设备及控制方法 技术领域
本发明属于洗涤设备技术领域,具体地说,涉及一种过滤系统、过滤模块、洗涤设备及控制方法。
背景技术
用于清洗衣物的洗涤设备,例如洗衣机,在对衣物进行洗涤的过程中,由于衣物与衣物之间,以及衣物与洗衣机本身存在摩擦,会造成衣物产生线屑脱落并混入洗涤水中。在洗衣机完成洗涤进行排水时,衣物上脱落的线屑会随排水水流一同排出。
然而,近些年提出的微塑料的概念在环保领域逐渐受到日益增加的重视,研究发现,微塑料的一种重要来源为家用洗衣机排出的废水。这是由于而随着化纤面料的普及,洗衣过程中脱落的衣物纤维随洗衣机排水水流排出即成为混入自然水环境的微塑料。微塑料随排水水流直接进入生态循环,会通过自然生物链最终在人体内累计,可能对人体健康造成影响。为此,在一些地区已对洗衣机排水中微塑料的含量制定了相关标准。
目前用于实现洗衣机排水过滤的方法一般是在排水通道上设置过滤器,例如在排水泵内部安装过滤器。但现有具备过滤功能的排水泵大多仅能够过滤较大尺寸的异物,防止异物堵塞排水通道,而水中的线屑,也即上述所述的微塑料并不能被排水泵中的过滤器有效拦截,仍会大量地混在排水水流中排出洗衣机。因此,如何针对洗涤设备排水水流中的线屑等过滤杂质进行有效过滤,是本领域亟待解决的问题。
进一步地,目前大多数洗衣机需要用户将过滤器取下手动清理,操作不便。现有技术中针对这一问题提出了具有自清理功能的过滤装置,可以自主排出附着的过滤杂质。但由于洗衣机内部空间较为紧凑,过滤装置向外排出污水的排污路径一般较长,且可能存在一定高度差,使得过滤装置内的污水在不借助驱动力的情况下很难充分排出,会导致洗衣结束后,过滤装置内存在污水残留的问题。在过滤装置长期使用后,仍然会存在细菌滋生等问题。
有鉴于此,特提出本发明。

实施例一
如图1至图5所示,本实施例提供一种洗涤设备的过滤系统,以及具有所述过滤系统的洗涤设备。其中,所述的洗涤设备可以是洗衣机、洗干一体机、护理机等具有衣物清洗功能的洗涤设备。
本实施例所述的过滤系统至少包括第一过滤水路和第二过滤水路。所述的第一过滤水路通过水泵400驱动,由洗涤设备的盛水筒100至少依次经过过滤器420和过滤装置600后向洗涤设备外部排水。所述的第二过滤水路由过滤装置600至少依次经过污水接收装置500和水泵400后向洗涤设备外部排水。
在上述方案中,所述的过滤系统至少具有两条可在过滤后向洗涤设备外部排水的过滤水路,洗涤设备向外排水时,分别位于两条过滤水路上的过滤器420、过滤装置600和污水接收装置500都可以对经过的排水水流进行过滤,拦截水中的过滤杂质,进而可以充分地除去水中的过滤杂质,减少洗涤设备排水水流中的过滤杂质含量。而第一过滤水路通过水泵400驱动,第二过滤水路也经过同一台水泵400,进而也可以依靠水泵400提供驱动力。在洗涤设备具有两条可向外排水的过滤水路时,不需要分别设置两台驱动装置,简化了洗涤设备进行过滤排水的动力结构。
作为本实施例的一种优选方案,所述第一过滤水路上,过滤器420用于过滤大于预设尺寸的过滤杂质,过滤装置600用于过滤小于等于预设尺寸的过滤杂质。
在上述方案中,沿第一过滤水路流动的水流依次经过过滤器420和过滤装置600,可实现对不同尺寸范围的过滤杂质进行逐级过滤,进而可以达到更好的过滤效果。同时,不同尺寸范围的过滤杂质分别被不同的过滤器拦截,能够有效避免过滤器上的过滤孔径与过滤杂质的尺寸差别较大时,容易造成过滤器堵塞的问题,有利于提高过滤效率。
具体地,过滤器420主要用于对盛水筒100中的水实现初步过滤效果,上述所述的大于预设尺寸的过滤杂质主要包括具有较大尺寸的杂物,例如随所洗衣物被带入盛水筒100中的硬币、发卡,或者从衣物上脱落的纽扣等异物。进而经过过滤器420之后的水流中不会包含上述的异物,可防止所述异物对第一过滤水路的后续管道,或过滤装置600造成堵塞,导致洗涤设备的过滤功能出现故障的问题。
在过滤器420完成初步过滤之后,再由过滤装置600进行进一步过滤,从而除去上述所述的小于等于预设尺寸的过滤杂质,如洗涤过程中从衣物表面脱落的线屑等。具体地,为保证洗涤设备的排水水流中尽可能不含有对生态环境存在危害的微塑料,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,所述的过滤杂质中可以包括微塑料。尤其是,过滤杂质中可以包括长度大于50μm,直径在10~1000μm的塑料纤维。优选地,所述的塑料纤维具有400~600μm的长度,在分布中最常见的长度在500μm±50μm。这些塑料纤维的直径优选为10~50μm,最常见的具有17μm±2μm的直径。
本实施例的进一步方案中,所述第二过滤水路至少在经过水泵400后并入所述第一过滤水路向外排水。也就是说,所述的第一过滤水路和第二过滤水路共用部分水路结构,更具体地,与洗涤设备外部空间直接连通,用于将排水水流导出洗涤设备的管路被上述两条过滤水路共用。这样的话,洗涤设备仅需设置一条 延伸至箱体10外部的排水管路250即可,更方便用户将洗涤设备排水导入家中的排水系统,例如地漏中。
进一步地,在所述第一过滤水路上,水泵400设置在盛水筒100与过滤装置600之间。所述第二过滤水路中,污水接收装置500与水泵400连通,使得第二过滤水路在水泵400处并入第一过滤水路中。
本实施例的具体方案中,过滤器420集成设置在水泵400内部,所述第一过滤水路至少包括:
盛水筒排水管260,用于由盛水筒100向水泵400导水;
中间管路220,用于由水泵400向过滤装置600导水;
排水管路250,用于向洗涤设备外部排水。
污水接收装置500与水泵400的内部腔室连通,经污水接收装置500过滤后的水进入水泵400中,并在水泵400的驱动作用下进一步沿第一过滤水路的中间管路220和排水管路250排出洗涤设备。
在上述方案中,水泵400内部设置所述过滤器420,沿第一过滤水路进入水泵400的水经过滤器420过滤除去大于预设尺寸的过滤杂质后,由水泵400的出水端被泵出,沿中间管路220被输送至过滤装置600,并最终沿排水管路250排出洗涤设备。沿第二过滤水路,污水接收装置500可将过滤后的水排入水泵400中,水泵400再将接收的水沿中间管路220和排水管路250泵出。
本实施例中,污水接收装置500具体包括壳体,以及设置在所述壳体内部的线屑收集组件560。线屑收集组件560对经过污水接收装置500的水流进行过滤,同时对水中携带的过滤杂质进行收集。
具体地,线屑收集组件560具有用于收集过滤杂质的收集腔。污水接收装置500接收过滤装置600沿所述第二过滤水路的排水,所接收的水流直接进入线屑收集组件560的收集腔中,再经线屑收集组件560过滤后流至线屑收集组件560外侧,可排入水泵400,过滤杂质则收集于所述收集腔中。
如图2和图6所示,在本实施例的进一步方案中,水泵400包括泵身410,污水接收装置500与泵身410接触设置,且设置在泵身410的上方。
具体地,泵身410具有与盛水筒100连通的进水端,以及连接至中间管路220的出水端。泵身410的顶部设置开口与污水接收装置500的壳体内部连通,用于接收污水接收装置500的排水。
优选地,泵身410与污水接收装置500的壳体一体设置,两者的内部空间相互连通。过滤装置600排水进入污水接收装置500后,经污水接收装置500内部的线屑收集组件560过滤,过滤后的水进一步在重力作用下排入水泵400的泵身410,进而可由水泵400泵送至排水管路250排出洗涤设备。
本实施例的进一步方案中,过滤装置600具有自清理功能,用户无需从洗涤设备中卸下过滤装置600进行手动清理,过滤装置600能够自主清理并随水流排出过滤过程中积累的过滤杂质。过滤装置600上设置排污口6103,可通过排污口6103排出自清理后携带过滤杂质的污水,防止过滤杂质在过滤装置600内部大量堆积,影响过滤效率。
而过滤器420和污水接收装置500需要用户定期清理,具体地,过滤器420可拆卸地安装在水泵400内部,线屑收集组件560可拆卸地安装在污水接收装置500的壳体内部。箱体10的前侧壁12上对应过滤器420和污水接收装置500的安装位置设置可开启的下边门18,用户开启下边门18,即可从水泵400中卸下过滤器420,或者从污水接收装置500中取出线屑收集组件560进行清理。
本实施例中,所述的第二过滤水路用于对过滤装置600进行自清理后所排出的污水进行过滤,再排出洗涤设备。具体地,过滤装置600由排污口6103携带过滤杂质的污水,所述污水进入污水接收装置500中实现过滤,过滤杂质被线屑收集组件560收集,而过滤后不含过滤杂质的污水才可以进入水泵400中,再被水泵400泵出排出洗涤设备。
通过上述方式,既可以实现过滤装置600无需用户干预即可排出过滤杂质的目的,又能够保证由过滤装置600排出的过滤杂质不会随洗涤设备的排水水流直接排出,避免了过滤杂质中的微塑料进入生态循环的问题。
在上述方案中,污水接收装置500用于实现过滤杂质的最终收集目的。如前所述,本实施例中的过滤装置600可以过滤出尺寸大于50μm的过滤杂质,其中包括微塑料,尤其是长度大于50μm,直径在10~1000μm的塑料纤维。为保证过滤装置600所排出污水中携带的以上尺寸的微塑料或塑料纤维可以被线屑收集组件560充分收集起来,线屑收集组件560对污水进行过滤时,能够过滤收集的过滤杂质尺寸至少要不小于过滤装置600所能过滤出的过滤杂质的尺寸。例如,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,那么线屑收集组件560对接收的污水进行过滤时,至少要保证尺寸大于50μm的过滤杂质不能通过,优选尺寸稍小于50μm的过滤杂质也不能通过,可确保污水中的微塑料尽可能多地收集在线屑收集组件560中。
本实施例的具体方案中,过滤装置600内部设置有用于实现过滤的过滤网,线屑收集组件560包括围成收集腔的滤网,过滤装置600排出的污水进入线屑收集组件560的收集腔中,通过所述滤网实现污水的 过滤以及过滤杂质的收集。
而为了实现对前述尺寸微塑料的过滤去除,过滤装置600内部的过滤网选择20目至500目。而为了保证污水接收装置500可以通过线屑收集组件560将污水中携带的微塑料尽可能充分地收集起来,不会出现过滤装置600过滤出的微塑料在污水接收装置500中可以穿过线屑收集组件560的问题,线屑收集组件560中滤网上孔径的尺寸至少不大于过滤装置600中过滤网的孔径,也即线屑收集组件560中的滤网的目数不小于过滤装置600中过滤网的目数20目至500目。
通过预先对不同种类衣物及不同洗涤程序进行大量的测试试验,发现将线屑收集组件560中的滤网的目数以及过滤装置600中过滤网的目数设置在本实施例所述的以上范围内,可以从洗涤水及洗涤设备排水中过滤出上述尺寸的塑料纤维,并最终可在污水接收装置500中收集到占水中总含量80%以上的微塑料颗粒,令最终洗涤设备的排水水流中微塑料含量大幅度下降,能够满足直接排放的标准。
本实施例的详细方案中,为实现过滤装置600的自清理功能,过滤装置600包括:
过滤腔体610,具有入水口6101、过滤水出口6102和排污口6103;
过滤机构620,可转动的设置在过滤腔体610内部,具有与过滤水出口6102的内壁可转动密封连接的出水接头621;
驱动机构660,与过滤机构620连接,用于驱动过滤机构620在过滤腔体610中转动。
过滤机构620包括过滤网支架,以及在过滤网支架表面覆盖的过滤网,将过滤腔体610内部分隔为外容腔与内容腔,其中入水口6101与所述外容腔连通。盛水筒100中待过滤的洗涤水经入水口6101进入外容腔中,通过过滤机构620进入内容腔实现过滤,水中携带的过滤杂质附着在过滤机构620的外壁上,滤除过滤杂质的清水经与内容腔连通的出水接头621流出,最终从过滤水出口6102流出过滤腔体610。
当需要清理过滤装置600内部的过滤杂质时,通过驱动机构660,如电机驱动过滤机构620转动,可搅动过滤腔体610内的水流,使过滤机构620外壁附着的过滤杂质在离心力及激荡水流的双重作用下剥离,融入过滤腔体610内水中,进而由过滤腔体610上的排污口6103随水流排出。
在上述方案中,通过设置可转动的过滤机构620,使得过滤装置600能够实现过滤杂质的自主清理,且过滤杂质的清除效率很高。正常使用情况下,用户无需将过滤装置600从洗涤设备中取出进行手动清理,洗涤设备的使用更加方便。
本实施例的进一步方案中,所述洗涤设备的过滤系统还包括排污控制装置,用于控制所述第二过滤水路的通断。当过滤装置600用于对水进行过滤时,通过所述排污控制装置切断第二过滤水路,可以保证进入过滤装置600的水都可以在过滤之后由过滤水出口6102流出,而不会出现待过滤的水进入过滤装置600之后,直接沿第二过滤水路流向污水接收装置500的情况。只有在过滤装置600进行自清理需要排出污水时,才控制所述排污控制装置导通第二过滤水路。
进一步地,所述第二过滤水路包括排污管路240,用于由过滤装置600向污水接收装置500导水。所述排污控制装置包括设置在排污管路240上的排污控制阀241。过滤装置600进行水的过滤时,排污控制阀241处于关闭状态,切断排污管路240,进而过滤装置600不会由排污口6103向外排水。过滤装置600需要排出污水时,排污控制阀241打开,从而排污管路240可导通过滤装置600与污水接收装置500,实现污水由过滤装置600排入污水接收装置500中。
本实施例的优选方案中,污水接收装置500设置在过滤装置600的下部,过滤装置600在重力作用下沿排污管路240向污水接收装置500排水。
更优地,过滤装置600设置在盛水筒100中心轴线所在高度的上方,污水接收装置500设置在盛水筒100中心轴线所在高度的下方。进一步地,由于本实施例中污水接收装置500与水泵400直接连通,且污水接收装置500的壳体与水泵400的泵身410一体设置,水泵400与污水接收装置500一同设置在盛水筒100中心轴线所在高度的下方。
进一步优选地,排污口6103设置在过滤装置600过滤腔体610的底部,确保了过滤腔体610内的污水可以由排污口6103充分排出,避免残留。
在上述方案中,过滤装置600中的污水可在重力作用下排入污水接收装置500中,而不需要再借助额外的驱动力。在第二过滤水路中,水泵400主要为污水接收装置500向外排水提供驱动力,而过滤装置600向污水接收装置500排水可以在不借助外部驱动力的情况下进行。尤其是在洗涤设备即将结束或已经结束本次洗涤程序的运行时,通过排污控制阀241保持打开状态并维持一定时长,过滤装置600中的残余水也可在重力作用下由排污口6103充分排出,有效防止了过滤装置600在洗涤设备工作结束后存在残余水的问题。
本实施例中,洗涤设备的箱体10包括相对设置的顶壁11和底壁17,以及环绕顶壁11及底壁17外周 的四个侧壁。盛水筒100设置在箱体10内部,盛水筒100的中心轴线沿箱体10的前后方向设置。
本实施例的优选方案中,箱体10的右侧壁14,顶壁11,以及盛水筒100的筒壁104共同构成第一安装空间M。同时,箱体10的右侧壁14,底壁17,以及盛水筒100的筒壁104共同构成第二安装空间N。过滤装置600设置在位于箱体10右侧上部区域的第一安装空间M内,水泵400和污水接收装置500一同设置在位于箱体10右侧下部区域的第二安装空间N内。
在上述方案中,盛水筒100与箱体10之间在箱体10内右侧上部区域形成了接近三棱柱状的第一安装空间M,同时还在箱体10内右侧下部区域形成了接近三棱柱状的第二安装空间N。过滤装置600和污水接收装置500分别设置在上述的第一安装空间M和第二安装空间N内部,既实现了污水接收装置500位于过滤装置600下部,可利用重力自动排出污水的目的,又可以充分利用箱体10内部空间,使洗涤设备的箱体10内部结构紧凑,有利于在减小洗涤设备整体体积的前提下,保证盛水筒100具有更大的容量。过滤装置600和污水接收装置500设置在盛水筒100的同一侧(图2至图4中为盛水筒100右侧),排污管路240可沿接近竖直方向延伸设置,结构简单,且污水依靠重力排出过滤装置600的效率高。
进一步优选地,洗涤设备还包括洗涤剂盒300,用于实现向盛水筒100中自动投放洗涤剂的功能。洗涤剂盒300设置在箱体10的左侧上部区域,具体安装于箱体10的顶壁11、左侧壁13和盛水筒100的筒壁104所构成的空间内。
本实施例的进一步方案中,所述洗涤设备的过滤系统还包括第三过滤水路,所述第三过滤水路通过水泵400驱动,由盛水筒100至少依次经过过滤器420和过滤装置600后回到所述盛水筒100。
进一步地,所述过滤系统还包括切换装置270,用于控制所述第一过滤水路和第三过滤水路择一导通。
在上述方案中,所述第一过滤水路用于实现洗涤设备的排水过滤功能,使排水水流经过滤去除过滤杂质后再向外排出。所述第三过滤水路用于实现洗涤设备的循环过滤功能,具体地,可在洗涤过程中使盛水筒100中的水不断循环经过过滤器420和过滤装置600,减少水中的线屑等过滤杂质,防止线屑附着在衣物上影响洗涤效果。通过切换装置270控制第一过滤水路和第三过滤水路择一导通,即可使洗涤设备的排水过滤功能和循环过滤功能择一运行。
第一过滤水路和第三过滤水路在由盛水筒100至过滤装置600的区间内共用管路结构,且两者都可以利用水泵400提供驱动力,也就是说,过滤系统的水泵400、过滤器420和过滤装置600都是即可用于排水过滤,又可用于循环过滤,可以简化洗涤设备的内部结构,省去需要设置过多的过滤装置或驱动装置,或者水路设计过于复杂的麻烦。
本实施例的进一步方案中,所述第三过滤水路包括回水管路230,用于向盛水筒100中回水。切换装置270分别连通过滤装置600、排水管路250和回水管路230,并控制排水管路250和回水管路230择一与过滤装置600导通。
本实施例中的水路结构具体如下。盛水筒100的底部连接盛水筒排水管260的一端,盛水筒排水管260的另一端连接至水泵400的进水端。水泵400的出水端连接中间管路220的一端,中间管路220的另一端与过滤装置600的入水口6101连接。过滤装置600的过滤水出口6102通过连通管路280与切换装置270的进水口连通,切换装置270的一个出水口连接回水管路230,另一个出水口连接排水管路250。切换装置270内部设置可活动的切换机构271,切换机构271动作令两个出水口择一与进水口导通,进而可控制回水管路230和排水管路250择一与过滤装置600的过滤水出口6102导通。
在上述方案中,当切换装置270导通回水管路230与过滤水出口6102时,水泵400运行可将盛水筒100中的水抽出,泵送至过滤装置600进行过滤,并在过滤后沿回水管路230重新回到盛水筒100中,从而可在洗涤设备的洗涤过程中对洗涤水进行循环管过滤,实现洗涤设备的循环过滤功能。当切换装置270导通排水管路250与过滤水出口6102时,水泵400运行将盛水筒100中的水泵送至过滤装置600,过滤后的水沿排水管路250排出,使得洗涤设备的排水水流经过滤之后再向外排出,实现了洗涤设备的排水过滤功能。
以下结合图2至图4对本实施例中洗涤设备的工作过程进行具体描述。
图2所示为洗涤设备在洗涤阶段和/或漂洗阶段对洗涤水进行循环过滤的循环过程。具体地,盛水筒100中盛水洗涤衣物,切换装置270处于导通连通管路280与回水管路230的状态,排污控制阀241关闭使排污管路240处于切断状态。水泵400开启,沿盛水筒排水管260抽出盛水筒100中的洗涤水,洗涤水经过水泵400内部的过滤器420实现初步过滤后,沿中间管路220泵送至过滤装置600实现进一步过滤。过滤后的洗涤水由过滤装置600的过滤水出口6102流出,沿连通管路280进入切换装置270,最终由回水管路230回到盛水筒100中。
图3所示为洗涤设备的排水过程。具体地,洗涤设备需要排水时,切换装置270切换至导通连通管路280与排水管路250的状态,排污控制阀241保持关闭状态。控制水泵400开启,沿盛水筒排水管260抽 出盛水筒100中的洗涤水,洗涤水经过水泵400内部的过滤器420实现初步过滤后,沿中间管路220泵送至过滤装置600实现进一步过滤。过滤后的洗涤水由过滤装置600的过滤水出口6102流出,沿连通管路280进入切换装置270,最终由排水管路250排出洗涤设备。
图4所示为洗涤设备中,过滤装置600进行自清理,并排出携带过滤杂质污水的排污过程。具体地,结合图5,开启驱动机构660带动过滤机构620在过滤腔体610转动,使过滤机构620外壁附着的过滤杂质在离心力及激荡水流的作用下被剥离,激荡水流同时还可以令过滤腔体610内壁可能附着的过滤杂质脱落,进而融入过滤腔体610内水中。打开排污控制阀241,过滤腔体610内携带过滤杂质的污水在重力作用下由排污口6103流出,并沿排污管路240排入污水接收装置500中。进入污水接收装置500的污水经线屑收集组件560过滤后,污水中的过滤杂质收集于线屑收集组件560内部,不含过滤杂质的污水排入水泵400中。控制切换装置270处于导通连通管路280与排水管路250的状态,通过开启水泵400可将除去过滤杂质的污水依次沿中间管路220、连通管路280和排水管路250排出洗涤设备。
本实施例中,洗涤设备的过滤系统共设置三条过滤水路。其中,第一过滤水路可对盛水筒100排出的洗涤水进行过滤,然后再排出洗涤设备。过滤装置600可沿第二过滤水路排出自清理后携带过滤杂质的污水,并且令污水经污水接收装置500过滤收集过滤杂质后再向外排出,如此实现了洗涤设备的排水水流中几乎不含有过滤杂质,避免了过滤杂质中携带的微塑料随洗涤设备排水直接排出的问题。
第三过滤水路用于实现洗涤设备的循环过滤功能,从而可减少洗涤水中的线屑含量,改善衣物洗涤效果。所述的过滤系统中,部分结构被以上的三条过滤水路中至少两条过滤水路共用,从而实现了尽可能简化过滤系统结构的目的。一方面可简化洗涤设备的内部结构,避免复杂结构占用过大安装空间,另一方面减少驱动装置、过滤装置的设置数量,还有利于降低洗涤设备的生产成本。
实施例二
如图1至图5所示,本实施例提供一种洗涤设备,包括盛水筒100和过滤装置600,过滤装置600用于接收盛水筒100中的水进行过滤。所述的洗涤设备可以是洗衣机、洗干一体机、护理机等具有衣物清洗功能的洗涤设备。
具体地,过滤装置600具有自清理功能,用户无需卸下过滤装置600进行手动清理,过滤装置600能够自主清理并随水流排出过滤过程中积累的过滤杂质。过滤装置600上设置排污口6103,可通过排污口6103排出自清理后携带过滤杂质的污水,防止过滤杂质在过滤装置600内部大量堆积,影响过滤效率。
本实施例的洗涤设备还包括污水接收装置500,其与过滤装置600的排污口6103连通,用于接收过滤装置600排出的污水。如此,避免了过滤装置600所排出的污水直接汇入洗涤设备的排水水流中向外排出的问题,从而可以防止过滤杂质中的微塑料随排水水流进入生态循环,对生态环境及人体健康造成危害,
本实施例中,污水接收装置500设置在低于过滤装置600的排污口6103所在高度的位置。这样的话,过滤装置600中携带过滤杂质的污水由排污口6103排出后,可在重力作用下排入污水接收装置500中,而不需要再借助额外的驱动力。洗涤设备内部无需为过滤装置600排出污水的排污过程单独设置驱动装置,就可以实现过滤装置600自动排出过滤杂质的功能。
进一步地,本实施例中排污口6103设置在过滤装置600的底部区域,朝下进行排水。当洗涤设备不再向过滤装置600输送盛水筒100中的洗涤水进行过滤时,例如在当前洗涤程序的最后一次排水结束之后,过滤装置600中残留的洗涤水可以在重力作用下由排污口6103排入污水接收装置500中,防止了过滤装置600中存在洗涤水残留的问题。
本实施例的进一步方案中,过滤装置600的设置位置高于盛水筒100的中心轴线所在高度,污水接收装置500的设置位置低于盛水筒100的中心轴线所在高度。过滤装置600与污水接收装置500之间设置排污管路240实现连通,过滤装置600中的污水在中重力作用下沿排污管路240排入污水接收装置500中。
优选地,排污管路240上设置排污控制阀241。当过滤装置600接收盛水筒100中的水进行过滤时,排污控制阀241关闭以切断排污管路240,确保进入过滤装置600的洗涤水可以在被过滤后输出,而不会在重力作用下直接由排污口6103排出并沿排污管路240排入污水接收装置500中。只有在过滤装置600需要排出其中积累的过滤杂质时,再打开排污控制阀241,令过滤装置600中的污水携带过滤杂质,沿排污管路240排入污水接收装置500中。
具体地,本实施例的过滤装置600包括:
过滤腔体610,具有入水口6101、过滤水出口6102和排污口6103;
过滤机构620,可转动的设置在过滤腔体610内部,具有与过滤水出口6102的内壁可转动密封连接的出水接头621;
驱动机构660,与过滤机构620连接,用于驱动过滤机构620在过滤腔体610中转动。
过滤机构620包括过滤网支架,以及在过滤网支架表面覆盖的过滤网,将过滤腔体610内部分隔为外容腔与内容腔,其中入水口6101与所述外容腔连通。盛水筒100中待过滤的洗涤水经入水口6101进入外容腔中,通过过滤机构620进入内容腔实现过滤,水中携带的过滤杂质附着在过滤机构620的外壁上,滤除过滤杂质的清水经与内容腔连通的出水接头621流出,最终从过滤水出口6102流出过滤腔体610。
当需要清理过滤装置600内部的过滤杂质时,通过驱动机构660,如电机驱动过滤机构620转动,可搅动过滤腔体610内的水流,使过滤机构620外壁附着的过滤杂质在离心力及激荡水流的双重作用下剥离,融入过滤腔体610内水中,进而由过滤腔体610上的排污口6103随水流排出。
在上述方案中,通过设置可转动的过滤机构620,使得过滤装置600能够实现过滤杂质的自主清理,且过滤杂质的清除效率很高。正常使用情况下,用户无需将过滤装置600从洗涤设备中取出进行手动清理,洗涤设备的使用更加方便。
本实施例的洗涤设备还包括箱体10,箱体10具体包括相对设置的顶壁11和底壁17,以及环绕顶壁11及底壁17外周的四个侧壁。盛水筒100设置在箱体10内部,盛水筒100的中心轴线沿箱体10的前后方向设置。
本实施例的优选方案中,箱体10的右侧壁14,顶壁11,以及盛水筒100的筒壁104共同构成第一安装空间M。同时,箱体10的右侧壁14,底壁17,以及盛水筒100的筒壁104共同构成第二安装空间N。过滤装置600设置在位于箱体10右侧上部区域的第一安装空间M内,污水接收装置500设置在位于箱体10右侧下部区域的第二安装空间N内。
在上述方案中,盛水筒100与箱体10之间在箱体10内右侧上部区域形成了接近三棱柱状的第一安装空间M,同时还在箱体10内右侧下部区域形成了接近三棱柱状的第二安装空间N。过滤装置600和污水接收装置500分别设置在上述的第一安装空间M和第二安装空间N内部,既实现了污水接收装置500低于过滤装置600排污口6103,可利用重力自动排出污水的目的,又可以充分利用箱体10内部空间,使洗涤设备的箱体10内部结构紧凑,有利于在减小洗涤设备整体体积的前提下,保证盛水筒100具有更大的容量。过滤装置600和污水接收装置500设置在盛水筒100的同一侧(图2至图4中为盛水筒100右侧),排污管路240可沿接近竖直方向延伸设置,结构简单,且污水依靠重力排出过滤装置600的效率高。
进一步优选地,洗涤设备还包括洗涤剂盒300,用于实现向盛水筒100中自动投放洗涤剂的功能。洗涤剂盒300设置在箱体10的左侧上部区域,具体安装于箱体10的顶壁11、左侧壁13和盛水筒100的筒壁104所构成的空间内。
本实施例的进一步方案中,污水接收装置500包括线屑收集组件560,污水接收装置500所接收的污水通过线屑收集组件560进行过滤,线屑收集组件560同时还可以对污水中携带的过滤杂质进行收集。
具体地,污水接收装置500包括壳体,线屑收集组件560设置在所述壳体内部,且具有用于收集过滤杂质的收集腔。过滤装置600排出的污水沿排污管路240排入污水接收装置500,进入线屑收集组件560的收集腔中,再经线屑收集组件560过滤后流至线屑收集组件560外侧,过滤杂质则收集于所述收集腔中。
详细地,线屑收集组件560包括围成所述收集腔的滤网,过滤装置600排出的污水进入线屑收集组件560的收集腔中,通过所述滤网实现污水的过滤以及过滤杂质的收集。
在上述方案中,污水进入污水接收装置500后经线屑收集组件560过滤,从而可将过滤杂质从污水中分离出来,方便用户直接对收集的过滤杂质进行处理,避免了过滤杂质混合在水中,无法对其进行有效处理的情况。
本实施例的优选方案中,线屑收集组件560可拆卸地安装在污水接收装置500内部,用户可从污水接收装置500中卸下线屑收集组件560,对其中收集的过滤杂质进行清理。清理完成后,再将线屑收集组件560重新安装至污水接收装置500上,污水接收装置500即可在洗涤设备下一次运行洗涤程序时继续接收过滤装置600排出的污水。
具体地,本实施例中在箱体10的前侧壁12上设置可开启的下边门18,下边门18的设置位置与污水接收装置500对应,使得污水接收装置500刚好位于下边门18内侧。当线屑收集组件560需要进行手动清理时,用户开启下边门18,即可从污水接收装置500中取出线屑收集组件560。
本实施例的进一步方案中,所述洗涤设备还包括与盛水筒100连通的排水装置,洗涤设备通过所述排水装置向外部排水。污水接收装置500与所述排水装置连通,其中过滤后的污水可经所述排水装置排出洗涤设备。
由于污水接收装置500内过滤后污水中不再含有过滤杂质,通过排水装置直接将其排出洗涤设备,不会造成微塑料进入生态循环的问题。同时,污水接收装置500可以定期或实时地将过滤后的污水排出,无需用户将污水接收装置500从洗涤设备中完整地取出以倒出其中的污水,更方便用户使用。另一方面,由于污水不会大量地存储在污水接收装置500中,进而对污水接收装置500容积的需求降低,可减小污水接 收装置500的体积。
进一步地,所述的排水装置包括水泵400和排水管路250。其中,水泵400的进水端与盛水筒100连通,可抽出盛水筒100中的水并由水泵400的出水端泵出。排水管路250通向洗涤设备外部,可接收水泵400泵出的水并排出洗涤设备。
本实施例中,污水接收装置500与水泵400连通,污水接收装置500中过滤后的污水可排入水泵400中,再由水泵400泵送至排水管路250排出。一方面,水泵400一般设置在盛水筒100下方,进而在本实施例中可以设置在与污水接收装置500较为接近的位置,便于污水接收装置500将过滤后的污水直接排入水泵400中。另一方面,水泵400为洗涤设备的排水提供驱动力,将污水接收装置500设置为与水泵400连通,可利用水泵400为污水接收装置500的排水提供辅助驱动力,确保污水接收装置500对接收的污水进行过滤后可充分排入水泵400中。
如图2和图6所示,在本实施例的进一步方案中,水泵400包括泵身410,污水接收装置500与泵身410接触设置,且设置在泵身410的上方。
具体地,泵身410具有与盛水筒100连通的进水端,以及将水泵出水泵400的出水端。泵身410的顶部设置开口与污水接收装置500的壳体内部连通,用于接收污水接收装置500的排水。
优选地,泵身410与污水接收装置500的壳体一体设置,两者的内部空间相互连通。过滤装置600排出的污水进入污水接收装置500后,经污水接收装置500内部的线屑收集组件560过滤,过滤后的污水进一步在重力作用下排入水泵400的泵身410,进而可由水泵400泵送至排水管路250排出洗涤设备。
进一步地,水泵400的出水端与过滤装置600的入水口6101连通,排水管路250与过滤装置600的过滤水出口6102连通,水泵400泵出的水经过滤装置600过滤后沿排水管路250排出洗涤设备。
在上述方案中,洗涤设备的排水水流先经过滤装置600过滤以除去过滤杂质之后,再沿排水管路250排放至洗涤设备外部。如此,确保了洗涤设备的排水水流中不存在过滤杂质,避免了过滤杂质中可能存在的微线屑随排水水流进入生态循环的问题。
本实施例的进一步方案中,所述洗涤设备还包括与盛水筒100连通的回水管路230,以及与过滤装置600的过滤水出口6102连通的切换装置270。切换装置270用于控制回水管路230和排水管路250择一与过滤装置600的过滤水出口6102导通。
详细地,盛水筒100的底部连接盛水筒排水管260的一端,盛水筒排水管260的另一端连接至水泵400的进水端。水泵400的出水端连接中间管路220的一端,中间管路220的另一端与过滤装置600的入水口6101连接。过滤装置600的过滤水出口6102通过连通管路280与切换装置270的进水口连通,切换装置270的一个出水口连接回水管路230,另一个出水口连接排水管路250。切换装置270内部设置可活动的切换机构271,切换机构271动作令两个出水口择一与进水口导通,进而可控制回水管路230和排水管路250择一与过滤装置600的过滤水出口6102导通。
在上述方案中,当切换装置270导通回水管路230与过滤水出口6102时,水泵400运行可将盛水筒100中的水抽出,泵送至过滤装置600进行过滤,并在过滤后沿回水管路230重新回到盛水筒100中,从而可在洗涤设备的洗涤过程中对洗涤水进行循环过滤,实现洗涤设备的循环过滤功能。当切换装置270导通排水管路250与过滤水出口6102时,水泵400运行将盛水筒100中的水泵送至过滤装置600,过滤后的水沿排水管路250排出,使得洗涤设备的排水水流经过滤之后再向外排出,实现了洗涤设备的排水过滤功能。
洗涤设备的循环过滤与排水过滤通过同一水泵400提供驱动力,利用同一过滤装置600实现过滤效果,同时还共用了部分管路结构,有利于简化洗涤设备内部的水路结构。一方面,水路结构的简化节省了安装空间,另一方面,由于不需要分别设置循环泵和排水泵,减少了驱动装置的设置数量,有利于降低洗涤设备的生产成本。
本实施例的进一步方案中,水泵400还包括过滤器420,过滤器420设置在水泵400的进水端与出水端之间,具体设置在泵身410内部。由所述进水端进入水泵400的水经过滤器420过滤后,再由出水端泵出,并沿中间管路220被泵送至过滤装置600实现过滤。
优选地,过滤器420能够过滤的杂物的尺寸大于过滤装置600能够过滤的过滤杂质的尺寸。过滤装置600能够过滤的过滤杂质的尺寸大于等于污水接收装置500中线屑收集组件560能够收集的过滤杂质的尺寸。
具体地,水泵400中的过滤器420主要用于对盛水筒100中的水实现初步过滤效果,除去一些较大尺寸的杂物,例如随所洗衣物被带入盛水筒100中的硬币、发卡,或者从衣物上脱落的纽扣等异物。上述异物随水流经过水泵400时,被过滤器420拦截而不会由水泵400的出水端被泵出,可防止所述异物对中间管路220或过滤装置600造成堵塞,导致洗涤设备的过滤功能出现故障的问题。
优选地,过滤器420可拆卸地安装在水泵400上,用户可卸下过滤器420进行清理。具体地,水泵400与污水接收装置500的壳体一体设置在箱体10内部右下区域的第二安装空间N内,且两者共同位于箱体10前侧壁12上设置的下边门18内侧。用户开启下边门18,可同时露出水泵400与污水接收装置500,进而可按需拆卸水泵400的过滤器420和/或污水接收装置500的线屑收集组件560进行清理。
进一步地,在水泵400的过滤器420对水进行初步过滤之后,由过滤装置600进行进一步过滤,从而除去尺寸小于上述异物尺寸的过滤杂质,如洗涤过程中从衣物表面脱落的线屑等。具体地,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,所述的过滤杂质中可以包括微塑料。尤其是,过滤杂质中可以包括长度大于50μm,直径在10~1000μm的塑料纤维。优选地,所述的塑料纤维具有400~600μm的长度,在分布中最常见的长度在500μm±50μm。这些塑料纤维的直径优选为10~50μm,最常见的具有17μm±2μm的直径。
过滤装置600对所过滤出的过滤杂质进行清理,可将携带上述过滤杂质的污水排入污水接收装置500,通过污水接收装置500实现过滤杂质的最终收集目的。为保证污水中所携带的以上尺寸的微塑料或塑料纤维可以被线屑收集组件560充分收集起来,线屑收集组件560对污水进行过滤时,能够过滤收集的过滤杂质尺寸至少要不小于过滤装置600所能过滤出的过滤杂质的尺寸。例如,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,那么线屑收集组件560对接收的污水进行过滤时,至少要保证尺寸大于50μm的过滤杂质不能通过,优选尺寸稍小于50μm的过滤杂质也不能通过,可确保污水中的微塑料尽可能多地收集在线屑收集组件560中。
为实现对上述尺寸微塑料的过滤去除,过滤装置600中过滤机构620的过滤网选择20目至500目。而为了保证污水接收装置500可以将污水中携带的微塑料尽可能充分地收集起来,不会出现过滤装置600过滤出的微塑料在污水接收装置500中可以穿过线屑收集组件560的问题,线屑收集组件560中滤网上孔径的尺寸至少不大于过滤装置600中过滤网的孔径,也即线屑收集组件560中的滤网的目数不小于过滤装置600中过滤网的目数20目至500目。
本实施例中通过预先对不同种类衣物及不同洗涤程序进行大量的测试试验,发现将线屑收集组件560中的滤网的目数以及过滤装置600中过滤网的目数设置在以上的范围内,可以从洗涤水及洗涤设备排水中过滤出以上尺寸的塑料纤维,并最终可在污水接收装置500中收集到占水中总含量80%以上的微塑料颗粒,令最终洗涤设备的排水水流中微塑料含量大幅度下降,能够满足直接排放的标准。
本实施例中,洗涤设备的工作过程与实施例一中相同,不再赘述。
本实施例所提供的洗涤设备中设置具有自清理功能的过滤装置600,该过滤装置600既可以实现对洗涤水的循环过滤功能,又可以对洗涤设备的排水水流进行过滤,同时还可以自主清理内部积累的过滤杂质,无需用户取下过滤装置600进行手动清理,方便用户使用。洗涤设备中还设置污水接收装置500,可接收过滤装置600进行自清理之后排出的污水,并收集污水中的过滤杂质,避免了过滤杂质中携带的微塑料随洗涤设备排水直接排出的问题。
将过滤装置600设置在洗涤设备箱体10内部的上部区域,污水接收装置500设置在箱体10内部的下部区域,使得污水接收装置500的设置高度低于过滤装置600,尤其是使污水接收装置500低于过滤装置600的排污口6103,过滤装置600内部的污水可以不借助额外的驱动力,仅在重力作用下排入污水接收装置500中。同时,在洗涤设备即将结束本次洗涤程序的运行,或本次洗涤程序结束运行之后,排污控制阀241保持打开状态并维持一定时长,过滤装置600中的残余水也可在重力作用下由排污口6103充分排出,避免了过滤装置600中出现洗涤水残留的问题,保证了过滤装置600内部可在完成洗涤后尽快达到较为干燥的环境,保证了过滤装置600内部的清洁卫生。
实施例三
如图4和图7所示,本实施例与上述实施例一或二的区别在于:污水接收装置500与水泵400水平排布。具体地,污水接收装置500与水泵400的泵身410接触,且设置在泵身410的一侧(即图7中泵身410的左侧)。
进一步地,在本实施例中,泵身410的左侧设置开口与污水接收装置500的壳体内部连通,污水接收装置500内部过滤后的污水可经由所述开口进入水泵400中,再由水泵400泵送至排水管路250排出洗涤设备。
优选地,与上述实施例一类似,本实施例中泵身410与污水接收装置500同样为一体设置,且内部空间相互连通。过滤装置600向污水接收装置500排入污水之后,开启水泵400,可将污水接收装置500中经线屑收集组件560过滤后的污水抽吸至泵身410内部,再沿中间管路220向上泵送,最终由排水管路250排出洗涤设备。
本实施例中,在实施例一、二的基础上,仅改变污水接收装置500与水泵400的排布方式,其他结构 均与实施例一或二中相同,过滤系统的整体结构不变,仍包括用于实现不同功能的三条过滤水路,也可以实现过滤装置600在重力作用下将污水排入污水接收装置500中,再通过水泵400将污水接收装置500内过滤后的污水排出洗涤设备的效果。
实施例四
如图4和图8所示,本实施例与上述实施例一或二的区别在于:污水接收装置500与水泵400的泵身410间隔设置,两者之间通过排出管590连通。
本实施例的优选方案中,污水接收装置500上用于连接排出管590的出口高于泵身410上用于连接排出管590的入口。过滤装置600中的污水沿排污管路240排入污水接收装置500之后,经污水接收装置500中的线屑收集组件560实现过滤,过滤后的污水可在重力作用下沿排出管590被输送至水泵400的泵身410内部,进而通过水泵400的泵送作用最终沿排水管路250排出。
具体地,污水接收装置500的壳体下部设置与排出管590一端连接的出口,泵身410的下部设置与排出管590另一端连接的入口,污水接收装置500的设置高度略高于水泵400的设置高度,使得所述出口的所在高度高于入口的所在高度。排出管590由污水接收装置500壳体上的出口延伸至泵身410上的入口,整体呈倾斜向下延伸的结构,进而污水接收装置500内过滤后的污水可以在重力作用下自动沿排出管590排入水泵400的泵身410内部,污水接收装置500内部不会存在污水残留。
本实施例中,洗涤设备的其他结构均与上述实施例一、二中相同,进而也能够实现通过三条过滤水路分别实现不同过滤功能的目的,同时过滤装置600可以仅依靠重量作用将污水排入污水接收装置500,防止过滤装置600内部存在洗涤水残留。污水接收装置500与水泵400分体间隔设置并通过排出管590连通,以实现污水接收装置500中过滤后的污水被输送至水泵400进而排出。如此,利用现有技术中用于洗涤设备的排水泵进行简单改造,在其上增加用于接收污水的入口,即可得到本实施例的水泵400,省去了需要重新设计泵身410结构的麻烦。污水接收装置500略高于水泵400设置,污水接收装置500中过滤后的污水在重力作用下即可充分排入水泵400中,可避免污水接收装置500中存在污水残留的问题。
实施例五
本实施例与上述实施例一的区别在于:所述第二过滤水路中,污水接收装置与第一过滤水路位于盛水筒和水泵之间的部分连通。
具体地,本实施例中,盛水筒与水泵之间通过盛水筒排水管连通,所述污水接收装置通过管路与盛水筒排水管连通。
本实施例中,所述污水接收装置的壳体上设置排出口,并连接有出水管路。所述盛水筒排水管上设置三通结构,所述出水管路的端部连接在所述三通结构上,从而与盛水筒排水管连通。
通过上述结构,盛水筒排水管可以直接由盛水筒向水泵导水,污水接收装置中过滤后的污水也可以沿出水管路流向所述三通结构,并通过所述三通结构进入盛水筒排水管中,进而沿盛水筒排水管被导入水泵中。
本实施例中,污水接收装置与盛水筒排水管连通,而不是直接过滤后的污水送入水泵中。与上述的实施例一、三和四相比,本实施例中的水泵可以直接采用现有技术中用于洗涤设备的排水泵,不需要对其结构进行改动。
实施例六
如图9至图13所示,本实施例提供一种过滤模块,以及具有所述过滤模块的洗涤设备,所述过滤模块应用于洗涤设备时用于实现对水的过滤功能。所述的洗涤设备可以是洗衣机、洗干一体机、护理机等具有衣物清洗功能的洗涤设备。
具体地,所述的洗涤设备包括盛水筒100,所述的过滤模块与盛水筒100连通,用于对盛水筒100中的水进行过滤。
本实施例中,所述过滤模块具体包括过滤装置600和污水接收装置500。其中,过滤装置600具有自清理功能,其上设置排污口6103,可通过排污口6103排出自清理后所产生的污水,所述污水中携带有过滤过程中积累的过滤杂质。污水接收装置500与过滤装置600的排污口6103连通,用于接收过滤装置600排出的污水。
在上述方案中,过滤模块的过滤装置600用于接收洗涤设备盛水筒100中的水进行过滤,且过滤装置600具有一定的自清理能力,可以将过滤过程累积的过滤杂质排入污水接收装置500中,避免过滤杂质大量累积影响过滤效率。污水接收装置500接收过滤装置600排出的污水,而不是将所述污水汇入洗涤设备的排水水流中直接排出,避免了过滤杂质中含有的微塑料直接随洗涤设备排水进入生态循环的问题。
过滤模块整体安装在洗涤设备内部,用户在使用洗涤设备时,无法直接观察到过滤模块的状态,尤其 是其中过滤杂质的积累情况。而一旦出现过滤杂质过多的情况,可能导致污水接收装置500被过滤杂质堵塞,过滤装置600内的污水无法继续排入污水接收装置500,进而使过滤模块无法继续实现过滤功能。
为此,本实施例的过滤模块还设置有检测装置900,用于检测污水接收装置500是否发生堵塞。具体地,所述过滤模块设置有排污管路240,用于连接污水接收装置500与过滤装置600的排污口6103,实现污水由过滤装置600向污水接收装置500的输送。排污管路240上连接有检测支路249,检测支路249在污水接收装置500发生堵塞时将污水导向检测装置900。
通过上述结构,当污水接收装置500出现堵塞故障时,由于过滤装置600排出的污水无法进入污水接收装置500,就会沿检测支路249被导向检测装置900。当检测装置900检测到流入的污水时,即可判断污水接收装置500发生堵塞。如此,过滤模块能够通过检测装置900及时地检测到污水接收装置500的堵塞故障,进而可向洗涤设备的控制系统反馈相应的信息,使得洗涤设备能够对污水接收装置500的堵塞故障及时做出响应,例如后续洗涤过程中控制过滤装置600不向污水接收装置500排放污水等,保证洗涤设备可以正常运行。
本实施例的进一步方案中,检测装置900具体包括内部具有接水腔911的外壳910,以及用于检测接水腔911内水位高度的检测组件。所述检测组件可在接水腔911内的水位高度达到预设高度时产生反馈信号,发送至洗涤设备的控制系统。洗涤设备的控制系统可以根据接收所述反馈信号的情况控制洗涤设备发出报警信号,进而及时提醒用户污水接收装置500的堵塞故障,以便用户能够在洗涤设备结束本次运行后对污水接收装置500进行清理,确保洗涤设备再次运行时污水接收装置500可以正常使用。
具体地,本实施例中的污水接收装置500可拆卸地安装在洗涤设备的箱体10上,用户可以定期对其进行清理,尤其是可清理其中接收污水后积累的过滤杂质。但当用户忘记及时清理污水接收装置500时,就可能发生污水接收装置500在洗涤设备运行过程中被过滤杂质堵塞的情况。检测装置900能够及时检测到污水接收装置500的堵塞故障,使得洗涤设备发出报警信号对用户进行提醒,进而用户可以及时获知污水接收装置500的堵塞故障并进行手动清理,排除故障。
本实施例中,检测装置900设置在排污管路240的上部,检测支路249优选由排污管路240的两端之间竖直向上延伸与检测装置900连通。当污水接收装置500可以正常接收过滤装置600所排出的污水时,污水在重力作用下一般不会沿检测支路249进入检测装置900。只有在污水接收装置500发生堵塞故障时,过滤装置600继续向外排出污水,所排出的污水才会沿检测支路249进入检测装置900中。
进一步地,本实施例所述的检测组件包括浮动件920和传感器930。其中,浮动件920设置在接水腔911内部,可随接水腔911内的水面高度变化上下运动。传感器930用于感应浮动件920的高度位置,在浮动件920随水面上升至预设高度时产生反馈信号。
本实施例的具体方案中,浮动件920具有磁性,传感器930为设置在外壳910顶部的干簧管940。浮动件920随水面运动至预设高度时,干簧管940在浮动件920的磁性作用下导通,从而产生反馈信号。
详细地,浮动件920可以包括一块永磁体,以及包裹于所述永磁体外部的包覆体。所述包覆体的密度小于水,例如可选用泡沫塑料材质,从而实现浮动件920可漂浮于水面上。或者,所述包覆体具有中空结构,从而使得浮动件920整体密度小于水,可漂浮于水面上。
干簧管940设置在外壳910的顶部外侧,以避免与进入接水腔911的污水接触。干簧管940连接有信号输出导线943,用于与洗涤设备的控制系统连接从而传输产生的反馈信号。参见图10和图11,当污水未进入接水腔911时,浮动件920静止于接水腔911底部,干簧管940内部的第一电极941和第二电极942在常态下不接触,即干簧管940处于断开状态。
当污水接收装置500发生堵塞时,过滤装置600排出的污水沿检测支路249进入接水腔911中。参见图12和图13,浮动件920随接水腔911内水面上涨而上升,达到一定高度时,干簧管940受到浮动件920的磁性作用,使得第一电极941和第二电极942接触,此时干簧管940处于导通状态,产生反馈信号,并通过信号输出导线943传输至洗涤设备的控制系统。
本实施例的进一步方案中,检测组件还包括导向部950,导向部950内部形成上下延伸的中空通道,浮动件920限位于所述中空通道中随水面上下运动。干簧管940设置在导向部950的上方。
具体地,导向部950具有竖直延伸的中空管状结构,从而在内部形成所述中空通道。导向部950的下端具有开口,用于连通所述中空通道与导向部950外部的空间,使得所述中空通道内的水面高度可随接水腔911内的水面高度同步变化。
进一步地,导向部950的上部区域设置若干透气孔(图中未示出),确保所述中空通道内的空气可以随水面的上升由所述透气孔排出,避免空气压力的存在导致中空通道内的水面与接水腔911内的水面存在高度差。
在上述方案中,浮动件920被限位于导向部950所形成的中空通道内,只能在所述中空通道内上下运 动,而不会在接水腔911内随意运动。也就是说,浮动件920始终在干簧管940正下方的区域内上下浮动,确保浮动件920随水面上升后,其向外周辐射的磁场可以作用在干簧管940上使干簧管940导通,避免了干簧管940无法被导通的问题。
本实施例中,污水接收装置500具体包括壳体510,以及安装在壳体510内部的收集组件570。收集组件570将壳体510内部分隔为上下分布的第一腔室531和第二腔室532。排污管路240的出水端与第一腔室531连通,携带过滤杂质的污水进入第一腔室531,经收集组件570过滤后进入第二腔室532,过滤杂质收集于第一腔室531中,也即收集于收集组件570的上侧表面。
污水接收装置500通过收集组件570可以将过滤杂质从其接收的污水中分离出来,当用户对污水接收装置500进行清理时,方便用户直接对收集的过滤杂质进行处理,避免了过滤杂质混合在水中,无法对其进行有效处理的情况。
详细地,收集组件570包括水平设置的框架及铺设在所述框架上的滤网,壳体510可插入/抽出的安装在洗涤设备的箱体10上,壳体510的上侧具有敞口,收集组件570可拆卸地安装在壳体510内部。需要对污水接收装置500,尤其是其中的收集组件570进行清理时,用户将壳体510从箱体10中抽出时,可通过壳体510上侧的敞口将收集组件570从壳体510内部卸下并取出进行清理,此时无需将污水接收装置500完全取下,操作更加方便。
优选地,污水接收装置500的壳体510上可以设置出水口(图中未示出)与第二腔室532连通,从而将第二腔室532内经过滤后不含过滤杂质的水向外排出,例如通过洗涤设备的排水系统直接排出洗涤设备,并不会产生排水水流中携带过滤杂质,导致存在微塑料排出风险的问题。这样的话,用户清理污水接收装置500时不需要手动倾倒出其中的污水,更加方便。同时,还避免了污水接收装置500在洗涤设备运行过程中被污水充满,造成污水接收装置500溢水的问题。
本实施例中,污水接收装置500发生堵塞故障可能是由于排污管路240与污水接收装置500的连接处被过滤杂质堵塞,导致污水无法进入污水接收装置500中。也可能是由于污水中过滤杂质的含量过高,造成收集组件570堵塞,污水无法被收集组件570过滤而进入第二腔室532中,进而造成第一腔室531被污水充满,过滤装置600继续排出污水无法进入污水接收装置500中而造成的堵塞。
本实施例中,过滤装置600的具体结构包括:
过滤腔体610,其上设置入水口6101、过滤水出口6102和排污口6103;
过滤机构620,可转动的设置在过滤腔体610内部,具有与过滤水出口6102可转动密封连接的出水接头621;
驱动机构660,与过滤机构620连接,用于驱动过滤机构620在过滤腔体610中转动。
过滤机构620将过滤腔体610内部分隔为外容腔与内容腔,其中入水口6101与所述外容腔连通,过滤水出口6102与内容腔连通。待过滤的水由入水口6101进入外容腔中,穿过过滤机构620进入内容腔实现过滤,水中携带的过滤杂质附着在过滤机构620的外壁上,滤除过滤杂质的水可经出水接头621由过滤水出口6102流出。
详细地,过滤机构620包括过滤网支架,以及覆盖在所述过滤网支架上的过滤网。所述过滤网支架的一端伸入过滤水出口6102形成出水接头621。
当需要清理过滤装置600内部的过滤杂质时,通过驱动机构660驱动过滤机构620转动,可搅动过滤腔体610内的水流,使过滤机构620外壁附着的过滤杂质在离心力及激荡水流的双重作用下剥离,融入过滤腔体610内水中。混合有过滤杂质的污水由过滤腔体610上的排污口6103随水流排出,通过排污管路240将污水输送至污水接收装置500中。
本实施例的进一步方案中,排污管路240上设置排污控制阀241,用于控制排污管路240的通断。检测支路249的上端与检测装置900连接,下端连接在排污管路240上且位于排污控制阀241与污水接收装置500之间。
当过滤装置600对接收的水进行过滤时,排污控制阀241处于关闭状态,切断排污管路240。由于检测支路249位于排污控制阀241的下游区域,排污口6103与检测支路249之间在排污控制阀241关闭时也不连通。此时,过滤装置600不会由排污口6103向外排水,进而可确保由入水口6101进入过滤装置600的水都可以在经过滤机构620过滤后由过滤水出口6102排出。
只有在过滤装置600需要排出污水时,才打开排污控制阀241,导通排污管路240。此时,过滤装置600可由排污口6103向污水接收装置500排放污水,检测支路249也可在污水接收装置500发生堵塞故障时向检测装置900导水,进而实现对污水接收装置500堵塞故障的检测。
本实施例中,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,所述的过滤杂质中可以包括微塑 料。尤其是,过滤杂质中可以包括长度大于50μm,直径在10~1000μm的塑料纤维。优选地,所述的塑料纤维具有400~600μm的长度,在分布中最常见的长度在500μm±50μm。这些塑料纤维的直径优选为10~50μm,最常见的具有17μm±2μm的直径。
过滤装置600对所过滤出的过滤杂质进行清理,可将携带上述过滤杂质的污水排入污水接收装置500,通过污水接收装置500实现过滤杂质的最终收集目的。为保证污水中所携带的以上尺寸的微塑料或塑料纤维可以被收集组件570充分收集起来,收集组件570对污水进行过滤时,能够过滤收集的过滤杂质尺寸至少要不小于过滤装置600所能过滤出的过滤杂质的尺寸。例如,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,那么收集组件570对接收的污水进行过滤时,至少要保证尺寸大于50μm的过滤杂质不能通过,优选尺寸稍小于50μm的过滤杂质也不能通过,可确保污水中的微塑料尽可能多地收集在收集组件570上侧。
为实现对上述尺寸微塑料的过滤去除,过滤装置600中过滤机构620的过滤网选择20目至500目。而为了保证污水接收装置500可以将污水中携带的微塑料尽可能充分地收集起来,不会出现过滤装置600过滤出的微塑料在污水接收装置500中可以穿过收集组件570的问题,收集组件570中滤网上孔径的尺寸至少不大于过滤装置600中过滤网的孔径,也即收集组件570中的滤网的目数不小于过滤装置600中过滤网的目数20目至500目。
本实施例中通过预先对不同种类衣物及不同洗涤程序进行大量的测试试验,发现将收集组件570中的滤网的目数以及过滤装置600中过滤网的目数设置在以上的范围内,可以从洗涤水中过滤出以上尺寸的塑料纤维,并最终可在污水接收装置500中收集到占水中总含量80%以上的微塑料颗粒,令最终洗涤设备的排水水流中微塑料含量大幅度下降,能够满足直接排放的标准。
以下结合图9和图10进一步说明安装有上述过滤模块的洗涤设备的具体结构。
所述的洗涤设备包括循环过滤管路,其进水端和出水端分别与盛水筒100连通。过滤装置600设置在所述循环过滤管路上,且所述循环过滤管路上还设置有水泵400。在洗涤设备洗涤衣物的过程中,开启水泵400,可驱动盛水筒100中的水沿循环过滤管路流动进入过滤装置600,并在过滤之后回到盛水筒100中。
详细地,盛水筒100底部连接盛水筒排水管260,盛水筒排水管260与水泵400的入口端连接,水泵400的出口端连接向上延伸设置的上排管路210,上排管路210的上端连通中间管路220,中间管路220再与过滤装置600的入水口6101连接。过滤装置600的过滤水出口6102通过回水管路230与盛水筒100连通。回水管路230的出水端具体连接在盛水筒100筒口处的窗垫110上,通过窗垫110向盛水筒100中回水。
优选地,回水管路230上设置回水控制阀231,用于控制回水管路230的通断。洗涤设备进行洗涤水的循环过滤时,回水控制阀231打开,向盛水筒100中回水。当过滤装置600需要排出清理污水时,关闭回水控制阀231以切断回水管路230,进而过滤装置600不能由过滤水出口6102向外出水,确保过滤装置600可以由排污口6103将污水充分排出。
本实施例的进一步方案中,上排管路210和中间管路220之间设置切换装置270,切换装置270的进水口连接上排管路210的上端。切换装置270具有第一出水口与第二出水口,所述第一出水口连接中间管路220,第二出水口连接向洗涤设备外部排水的外排管路250。切换装置270内部设置切换机构,用于控制第一出水口和第二出水口择一与所述进水口导通。
当洗涤设备进行洗涤水的循环过滤时,切换装置270的第一出水口与进水口导通,使得上排管路210与中间管路220连通,导通洗涤设备的循环过滤管路。当洗涤设备完成洗涤向外排水时,切换装置270的第二出水口与进水口导通,将上排管路210与外排管路250连通,开启水泵400,盛水筒100中的水即可沿上排管路210和外排管路250排出洗涤设备。
通过切换装置270的设置,洗涤设备通过同一台水泵400既可以实现洗涤过程中的循环过滤,还可以实现洗涤设备向外排水。同时,循环过滤与排水共用部分管路结构,简化了洗涤设备内部的水路。通过控制切换装置270的导通方向,即可实现循环过滤与排水的功能切换,控制逻辑简单。
本实施例还提供一种上述洗涤设备的控制方法,用于实现污水接收装置500发生堵塞故障时的自动报警。
具体地,若洗涤设备通过检测装置900判断污水接收装置500发生堵塞,则发出报警信号。由于检测装置900可以对污水接收装置500是否发生堵塞进行检测,当检测到污水接收装置500发生堵塞故障时,洗涤设备通过发出报警信号的方式提醒用户,便于用户及时了解污水接收装置500的工作情况,并尽快对污水接收装置500进行手动清理以排除堵塞故障。
本实施例中,检测装置900通过传感器930,也即干簧管940向洗涤设备的控制系统发出反馈信号的 方式,提示污水接收装置500存在堵塞故障。在本实施例的进一步方案中,洗涤设备持续接收到所述反馈信号超过预设时长,再发出报警信号。
详细地,当污水沿检测支路249进入检测装置900的外壳910,在接水腔911内具有一定的水位高度时,浮动件920随水面上升,使得干簧管940被导通,产生反馈信号并发送至洗涤设备的控制系统。
结合图14所示,洗涤设备的控制系统接收到所述反馈信号后开始计时,计算本次接收到所述反馈信号的持续时长T,并与预设时长T0进行比较。若当前的持续时长T大于预设时长T0,则控制洗涤设备发出报警信号。若T≤T0,则继续累计持续时长T,直至T>T0,或者由于干簧管940断开而不再接收到所述反馈信号。
本实施例中,虽然在污水接收装置500未发生堵塞故障时,污水一般不会进入检测装置900。但受限于检测支路249的延伸长度,若排污管路240中的水流量过大,可能会出现部分污水沿检测支路249冲入检测装置900的情况,此时有可能出现浮动件920随水面上浮的情况,进而触发干簧管940的第一电极941与第二电极942接通,产生反馈信号。
在上述方案中,洗涤设备只有在持续接收到反馈信号超过预设时长T0时,才会触发报警,避免了由于污水流量过大而导致干簧管940被短暂导通时,洗涤设备对污水接收装置500的堵塞故障产生误报警。
本实施例中,通过在过滤装置600与污水接收装置500之间的排污管路240上连接检测支路249并设置检测装置900,可实现对污水接收装置500堵塞故障的检测,保证洗涤设备的正常运行。洗涤设备可以在污水接收装置500出现堵塞故障时报警提示用户,以便用户及时对污水接收装置500进行清理,避免影响后续使用。洗涤设备只有在持续接收到检测装置900所发出的反馈信号时,才进行报警提示,减少了误报警的几率,对污水接收装置500堵塞故障的报警更加准确。
实施例七
本实施例与上述实施例六的区别在于:所述的干簧管设置在检测装置的外壳底部,当接水腔内没有水时,磁性浮动件位于接水腔底部,干簧管在浮动件的磁性作用下呈导通状态。当污水进入接水腔内,浮动件随水面上浮,与干黄管分离达到一定距离时,干簧管不再受到浮动件的磁性作用,其中的第一电极和第二电极断开,此时可产生向洗涤设备的控制系统发送的反馈信号。
本实施例中,仅改变了干簧管的设置位置,其他结构均与上述实施例六相同,同样具有可及时检测污水接收装置堵塞故障的效果。
实施例八
本实施例与上述实施例六的区别在于:所述的传感器为磁场强度传感器,可检测外周磁场强度的变化。
当接水腔内无水时,磁性浮动件静止于接水腔的底部,与所述磁场强度传感器之间的距离较大,进而所述磁场强度传感器所检测到的磁场强度偏低。而当污水接收装置堵塞而导致污水进入接水腔时,浮动件随水面上升逐渐接近磁场强度传感器,进而所检测到的磁场强度逐渐增大。
本实施例中,当检测的磁场强度达到设定阈值时,产生反馈信号发送至洗涤设备的控制系统。当洗涤设备的控制系统持续接收到所述反馈信号超过预设时长,也即检测的磁场强度在不低于设定阈值的范围内持续超过预设时长时,说明污水接收装置发生堵塞故障,洗涤设备发出报警信号。
本实施例的进一步方案中,所述的磁场强度传感器还可以与实施例六中的干簧管共同应用。也即,既通过干簧管的通断判断浮动件是否随水面上浮,同时还通过磁场强度传感器检测磁场强度变化以判断浮动件的位置。通过以上两种方式共同检测,进一步提高对污水接收装置堵塞故障的检测准确性。
本实施例中,过滤模块及洗涤设备的其他结果均与实施例六中相同,不再赘述。
实施例九
本实施例与上述实施例六的区别在于:所述的传感器为接触开关,设置在所述导向部的内壁上部区域,或者设置在导向部顶端对应的外壳内壁上。
本实施例中,所述的浮动件无需具有磁性,只要可漂浮于水面上,从而实现可随水面高度变化上下运动即可。当接水腔内无水时,浮动件静止于接水腔的底部,与所述的接触开关分离。而当污水接收装置堵塞而导致污水进入接水腔时,浮动件随水面逐渐上升。当接水腔内水位达到一定高度时,浮动件随水面上升与所述接触开关接触,可触发所述接触开关产生反馈信号。
进一步地,当浮动件持续触发所述接触开关超过预设时长,也即此时洗涤设备的控制系统持续接收到反馈信号超过预设时长,说明污水接收装置发生堵塞故障,洗涤设备发出报警信号。
与上述实施例三类似,本实施例也可以与上述实施例六和三的方案结合应用,也即检测装置同时设置由接触开关,以及干簧管和/或磁场强度传感器。洗涤设备的控制系统可同时接收接触开关,以及干簧管和/或磁场强度传感器发出的反馈信号,综合分析判断污水接收装置是否发生堵塞故障,进一步提高检测的准 确性。
实施例十
本实施例与上述实施例六的区别在于:所述的检测组件为水位传感器,可在接水腔内的水位高度达到预设高度时产生反馈信号。
作为本实施例的一种具体实施方式,所述的水位传感器为设置在接水腔内壁一定高度处的两个水位探针。当接水腔内的水位高度达到预设高度时,所述的两个水位探针与水接触,令检测电路导通,从而产生反馈信号。
作为本实施例的另一种具体实施方式,所述的水位传感器为设置在接水腔底壁或侧壁底部区域的压力传感器,通过所述压力传感器检测水压信息,进而确定接水腔内的水位高度。当水位高度达到预设高度时,产生反馈信号发送至洗涤设备的控制系统。
本实施例的进一步方案中,所述的检测组件还可以包括浮动件和传感器的组合。所述水位传感器直接检测接水腔内的水位高度,所述传感器检测浮动件随水面上升的高度。洗涤设备的控制系统同时接收所述水位传感器产生的反馈信号,以及和与浮动件配合的传感器所产生的反馈信号,只有在所接收的两个反馈信号的持续时间都超过预设时长时,才判断污水接收装置发生堵塞故障,进而控制洗涤设备发出报警信号。
在上述方案中,所述的浮动件和传感器的组合可以采用实施例六至九中任意一项实施例的方案。
本实施例中,水位传感器与浮动件和传感器的组合配合应用,可进一步提高对污水接收装置是否发生堵塞的检测准确性。尤其是,当浮动件卡在导向部中无法随水面下降时,避免了对应的传感器持续产生反馈信号,导致洗涤设备对污水接收装置堵塞的误判。
实施例十一
如图15至图20所示,本实施例提供一种过滤模块,以及具有所述过滤模块的洗涤设备,所述过滤模块应用于洗涤设备时用于实现对水的过滤功能。所述的洗涤设备可以是洗衣机、洗干一体机、护理机等具有衣物清洗功能的洗涤设备。
具体地,所述的洗涤设备包括盛水筒100,所述的过滤模块与盛水筒100连通,用于对盛水筒100中的水进行过滤。
本实施例中,所述过滤模块具体包括过滤装置600和污水接收装置500。其中,过滤装置600具有自清理功能,其上设置排污口6103,可通过排污口6103排出自清理后所产生的污水,所述污水中携带有过滤过程中积累的过滤杂质。污水接收装置500设置在过滤装置600的排污口6103下游,可接收过滤装置600排出的污水。
在上述方案中,过滤模块的过滤装置600用于接收洗涤设备盛水筒100中的水进行过滤,且过滤装置600具有一定的自清理能力,可以将过滤过程累积的过滤杂质排入污水接收装置500的收集组件570中,避免过滤杂质大量累积影响过滤效率。利用污水接收装置500接收过滤装置600排出的污水,而不是将所述污水汇入洗涤设备的排水水流中直接排出,避免了过滤杂质中含有的微塑料直接随洗涤设备排水进入生态循环的问题。
具体地,本实施例中,污水接收装置500的内部设置收集组件570,收集组件570具有用于收集污水中过滤杂质的收集腔571,收集腔571与过滤装置600的排污口6103连通。过滤装置600排出的污水直接进入收集腔571中,收集组件570可以对污水进行过滤,从而将污水中的线屑等过滤杂质收集于收集腔571中。
本实施例的收集组件570可拆卸地安装在污水接收装置500内部。当收集腔571中积累的过滤杂质达到一定量时,用户可将收集组件570从污水接收装置500中卸下进行清理,然后再将清理完成的收集组件570重新装回污水接收装置500,等待后续使用。
然而,收集组件570在污水接收装置500内部可拆卸,就很有可能出现收集组件570安装不到位,甚至用户忘记安装收集组件570的情况。此时如果洗涤设备运行并利用过滤模块实现过滤功能,就会造成过滤杂质无法被收集于收集腔571中的问题。
为了保证收集组件570可以实现对过滤杂质的有效收集,本实施例的过滤模块还设置有位置检测装置,用于检测收集组件570在污水接收装置500中是否安装到位。通过所述位置检测装置,可以反馈收集组件570的安装情况,进而洗涤设备可以在收集组件570未安装到位时及时提醒用户,避免洗涤设备在收集组件570未安装到位的情况下运行。如此,防止了过滤装置600在收集组件570未安装到位的情况下进行污水排出,导致污水中的过滤杂质无法被有效收集的问题。
本实施例的进一步方案中,污水接收装置500包括容纳壳体510,收集组件570安装在容纳壳体510内部。所述位置检测装置包括设置在容纳壳体510上的检测元件,以及设置在收集组件570上的被检测元 件。所述被检测元件位于检测元件的有效检测范围内时,可触发所述检测元件,进而实现对收集组件570是否安装到位的检测。
可以理解的是,所述检测元件和被检测元件的设置位置可以对调,也即,所述检测元件设置在收集组件上,所述被检测元件设置在所述容纳壳体上,同样可以实现对收集组件是否安装到位的检测。
进一步地,本实施例中,所述检测元件为设置在容纳壳体510上的干簧管820,所述被检测元件为设置在收集组件570上的磁性件810。所述位置检测装置还包括检测电路,干簧管820设置在所述检测电路上。收集组件570在污水接收装置500中安装到位时,磁性件810位于干簧管820的有效检测范围内,进而干簧管820在磁性件810的作用下导通所述检测电路。
详细地,干簧管820内部具有第一电极821和第二电极822,并通过信号输出导线823串联入所述检测电路中。第一电极821和第二电极822在常态下不接触,使得所述检测电路处于断开状态。当收集组件570安装到位时,磁性件810位于靠近干簧管820的位置,干簧管820受到磁性件810的磁性作用,使得第一电极821和第二电极822接触,进而导通所述检测电路。洗涤设备根据所述检测电路的通断状态,即可判断收集组件570是否安装到位。
图16和图17中所示为本实施例中污水接收装置500的俯视结构图,图18所示为图17中的污水接收装置500沿虚线形成的剖面图。
如图18所示,本实施例的优选方案中,干簧管820设置在容纳壳体510的外侧,且贴合容纳壳体510的外壁设置。一方面,便于干簧管820上信号输出导线823的引出,另一方面,也减少了干簧管820与排入污水接收装置500的污水接触造成损坏的风险。
收集组件570包括围成收集腔571的收集腔壁572,磁性件810嵌入设置在收集腔壁572内部。收集腔壁572内嵌与干簧管820配合的磁性件810,避免了收集组件570反复拆卸时,磁性件810可能脱落的问题,进而保证了对收集组件570安装情况的有效检测。
进一步地,本实施例的过滤模块还包括排污管路240,排污管路240的一端(即其进水端)与过滤装置600的排污口6103连接,另一端(即其出水端)穿过容纳壳体510的侧壁与收集组件570的收集腔571连通。
所述检测元件干簧管820设置在容纳壳体510上供排污管路240穿过的侧壁上,也即图18中容纳壳体510的左侧壁。所述被检测元件磁性件810位于收集组件570与排污管路240连通的一侧,也即磁性件810内嵌于图18中收集腔壁572的左侧壁内。
在上述方案中,由于收集组件570与排污管路240连接实现对污水的接收以及对过滤杂质的收集,将干簧管820和磁性件810分别设置在接近排污管路240出水端的位置,可以更加准确地检测出收集组件570的当前安装位置是否可以实现与排污管路240出水端的有效连接。如此,当检测到收集组件570在污水接收装置500中安装到位时,可以确保排污管路240的出水端已和收集组件570有效连接,进而能够有效地收集污水中的过滤杂质,防止过滤杂质中的微塑料没有被拦截而随洗涤设备排水水流排出的问题。
详细地,如图18所示,当收集组件570在容纳壳体510中安装到位时,磁性件810靠近容纳壳体510外侧的干簧管820,使得干簧管820的第一电极821和第二电极822在磁性件810的磁性作用下相互接触,进而导通检测电路。
而如图19所示,当收集组件570在容纳壳体510中安装不到位时,由于磁性件810与干簧管820之间具有一定距离,进而干簧管820受到的磁性作用极弱,第一电极821和第二电极822保持分离,令检测电路处于断开状态。类似地,如图20所示,当容纳壳体510中未安装收集组件570时,干簧管820完全不受到磁场作用,进而第一电极821和第二电极822保持分离,令检测电路处于断开状态。
本实施例的详细方案中,收集腔壁572上开设若干透水孔,收集组件570还包括滤网,所述滤网覆盖于所述透水孔上,用于实现对所接收污水的过滤,从而将过滤杂质收集在收集腔571中。过滤装置600排出的污水沿排污管路240进入收集腔571内,过滤杂质被滤网拦截,收集于收集腔571内部,滤除过滤杂质的污水通过所述透水孔上的滤网,流至容纳壳体510中。
本实施例中,容纳壳体510可推拉地设置在洗涤设备的箱体10上,用户,拉出容纳壳体510,进而可以卸下内部的收集组件570,对其中收集的过滤杂质进行清理。通过收集组件570对污水进行过滤,可以将过滤杂质从水中分离出来,避免过滤杂质混在水中用户难以处理的问题。
本实施例的优选方案中,容纳壳体510上可以设置一出水口(图中未示出),用于排出过滤后的水。所述出水口可以与洗涤设备的盛水筒100连通,将过滤之后不含过滤杂质的水通入盛水筒100中重新利用。或者,所述出水口还可以通向洗涤设备外部,将过滤后不含过滤杂质的水排出洗涤设备。
通过在容纳壳体510上设置可自主排水的出水口,避免了过滤装置600排出的污水在容纳壳体510内 的留存,进而可以减小容纳壳体510的内部容积,而不会出现洗涤设备运行过程中污水接收装置500溢水的问题。同时,用户拉出容纳壳体510进行清理时,只需要卸下收集组件570清理其内部的过滤杂质,而无需将容纳壳体510从箱体10上取下,从而手动倾倒出其中积存的污水,更加方便。
本实施例的进一步方案中,所述过滤模块的过滤装置600具体包括:
过滤腔体610,其上设置入水口6101、过滤水出口6102和排污口6103;
过滤机构620,可转动的设置在过滤腔体610内部,具有与过滤水出口6102可转动密封连接的出水接头621;
驱动机构660,与过滤机构620连接,用于驱动过滤机构620在过滤腔体610中转动。
过滤机构620将过滤腔体610内部分隔为外容腔与内容腔,其中入水口6101与所述外容腔连通,过滤水出口6102与内容腔连通。待过滤的水由入水口6101进入外容腔中,穿过过滤机构620进入内容腔实现过滤,水中携带的过滤杂质附着在过滤机构620的外壁上,滤除过滤杂质的水可经出水接头621由过滤水出口6102流出。
详细地,过滤机构620包括过滤网支架,以及覆盖在所述过滤网支架上的过滤网。所述过滤网支架的一端伸入过滤水出口6102形成出水接头621。
当需要清理过滤装置600内部的过滤杂质时,通过驱动机构660驱动过滤机构620转动,可搅动过滤腔体610内的水流,使过滤机构620外壁附着的过滤杂质在离心力及激荡水流的双重作用下剥离,融入过滤腔体610内水中。混合有过滤杂质的污水由过滤腔体610上的排污口6103随水流排出,通过排污管路240将污水输送至污水接收装置500中。
进一步优选地,过滤腔体610内壁与过滤机构620外壁之间还设置有清洗颗粒680,用于随水流摩擦碰撞清洗过滤腔体610内壁和过滤机构620外壁。在过滤过程中,清洗颗粒680随流动的水流不断摩擦过滤腔体610内壁和过滤机构620外壁,使附着的过滤杂质脱落,从而防止过滤杂质的沉积,避免过滤机构620过快被过滤杂质覆盖,影响过滤效率。另一方面,也避免了过滤完成后附着的过滤杂质厚度较大,在过滤腔体610内壁或过滤机构620外壁贴合过于牢固,导致后期清洁过滤装置600时,过滤杂质难以除去的问题。
而在驱动机构660驱动过滤机构620在过滤腔体610中转动实现自清理时,清洗颗粒680随激荡水流的作用在过滤腔体610中运动,与过滤腔体610内壁和过滤机构620外壁发生摩擦,从而提高过滤杂质的剥离效率,过滤装置600的自清洁效果更好。
过滤腔体610内还设置有挡板690,挡板690上设置过水孔691。清洗颗粒680设置在挡板690一侧(即图16中的左侧),过滤腔体610上的过滤水出口6102和排污口6103一同位于挡板690的另一侧(即图16中的右侧)。
通过挡板690的设置,在过滤过程中可防止清洗颗粒680向过滤水出口6102聚集,在过滤装置600进行自清理并排出污水时,污水携带过滤杂质可经过水孔691穿过挡板690由排污口6103排出,而清洗颗粒680被挡板690阻挡,不会由排污口6103随水流排出,避免了清洗颗粒680的损失。同时,还能够防止清洗颗粒680在排污口6103堆积,造成排污口6103堵塞,影响污水排出效率的情况。
本实施例的进一步方案中,在排污管路240上设置有排污控制阀241,用于控制排污管路240的通断。当过滤装置600对接收的水进行过滤时,排污控制阀241处于关闭状态,切断排污管路240。确保进入过滤装置600的水能够在过滤后由过滤水出口6102流出。在需要排出过滤装置600中的污水时,开启排污控制阀241以导通排污管路240,过滤装置600中的污水即可排入污水接收装置500中。
优选地,过滤装置600的过滤水出口6102连接回水管路230,用于输送过滤装置600过滤后的水。回水管路230上设置回水控制阀231,用于控制回水管路230的通断。过滤装置600进行过滤时,回水控制阀231为开启状态,而当控制过滤装置600排出污水时,将回水控制阀231关闭,令过滤装置600不能由过滤水出口6102出水,从而确保过滤装置600内的污水由排污口6103充分排出。
本实施例中,过滤装置600可以过滤出尺寸大于50μm的过滤杂质,所述的过滤杂质中可以包括微塑料。尤其是,过滤杂质中可以包括长度大于50μm,直径在10~1000μm的塑料纤维。优选地,所述的塑料纤维具有400~600μm的长度,在分布中最常见的长度在500μm±50μm。这些塑料纤维的直径优选为10~50μm,最常见的具有17μm±2μm的直径。
过滤装置600对所过滤出的过滤杂质进行清理,可将携带上述过滤杂质的污水排入污水接收装置500,通过污水接收装置500内部的收集组件570实现过滤杂质的最终收集目的。为保证污水中所携带的以上尺寸的微塑料或塑料纤维可以被收集组件570充分收集起来,收集组件570对污水进行过滤时,能够过滤收集的过滤杂质尺寸至少要不小于过滤装置600所能过滤出的过滤杂质的尺寸。例如,过滤装置600可以过 滤出尺寸大于50μm的过滤杂质,那么收集组件570对接收的污水进行过滤时,至少要保证尺寸大于50μm的过滤杂质不能通过,优选尺寸稍小于50μm的过滤杂质也不能通过,可确保污水中的微塑料尽可能多地收集在收集组件570的收集腔571中。
为实现对上述尺寸微塑料的过滤去除,过滤装置600中过滤机构620的过滤网选择20目至500目。而为了保证污水接收装置500内部的收集组件570可以将污水中携带的微塑料尽可能充分地收集起来,避免出现过滤装置600过滤出的微塑料在污水接收装置500中可以穿过收集组件570中滤网的情况,收集组件570的滤网上孔径的尺寸至少不大于过滤装置600中过滤网的孔径,也即收集组件570中的滤网的目数不小于过滤装置600中过滤网的目数20目至500目。
本实施例中通过预先对不同种类衣物及不同洗涤程序进行大量的测试试验,发现将收集组件570中的滤网的目数以及过滤装置600中过滤网的目数设置在以上的范围内,可以从洗涤水中过滤出以上尺寸的塑料纤维,并最终可在收集组件570内收集到占水中总含量80%以上的微塑料颗粒,令最终洗涤设备的排水水流中微塑料含量大幅度下降,能够满足直接排放的标准。
以下结合图15和图16进一步说明安装有本实施例所述过滤模块的洗涤设备的具体结构。
所述的洗涤设备包括循环过滤管路,其进水端和出水端分别与盛水筒100连通。所述过滤模块的过滤装置600设置在所述循环过滤管路上,且所述循环过滤管路上还设置有水泵400。在洗涤设备洗涤衣物的过程中,开启水泵400,可驱动盛水筒100中的水沿循环过滤管路流动进入过滤装置600,并在过滤之后回到盛水筒100中。
详细地,盛水筒100底部连接盛水筒排水管260,盛水筒排水管260与水泵400的入口端连接,水泵400的出口端连接绕至盛水筒100后方向上延伸设置的上排管路210,上排管路210的上端连通中间管路220,中间管路220再与过滤装置600的入水口6101连接。过滤装置600的过滤水出口6102通过回水管路230与盛水筒100连通。回水管路230的出水端具体连接在盛水筒100筒口处的窗垫110上,通过窗垫110向盛水筒100中回水。
本实施例的进一步方案中,上排管路210和中间管路220之间设置切换装置270,切换装置270的进水口连接上排管路210的上端。切换装置270具有第一出水口与第二出水口,所述第一出水口连接中间管路220,第二出水口连接向洗涤设备外部排水的外排管路250。切换装置270内部设置切换机构,用于控制第一出水口和第二出水口择一与所述进水口导通。
当洗涤设备进行洗涤水的循环过滤时,切换装置270的第一出水口与进水口导通,使得上排管路210与中间管路220连通,导通洗涤设备的循环过滤管路。当洗涤设备完成洗涤向外排水时,切换装置270的第二出水口与进水口导通,将上排管路210与外排管路250导通,开启水泵400,盛水筒100中的水即可沿上排管路210和外排管路250排出洗涤设备。
通过切换装置270的设置,洗涤设备通过同一台水泵400既可以实现洗涤过程中的循环过滤,还可以实现洗涤设备向外排水。同时,循环过滤与排水共用部分管路结构,简化了洗涤设备内部的水路。通过控制切换装置270的导通方向,即可实现循环过滤与排水的功能切换,控制逻辑简单。
本实施例中,洗涤设备设置有过滤模块,可在运行过程中对洗涤水进行循环过滤,防止线屑等附着在洗完的衣物上,改善衣物的洗涤效果。过滤模块中用于实现洗涤水过滤的过滤装置600具有自清理功能,可以自主排出过滤过程中积累的线屑等过滤杂质。所述过滤模块还具有污水接收装置500,可以利用内部的收集组件570接收过滤装置600排出的污水,进而实现对污水中过滤杂质的收集,能够防止所述污水直接排出会造成过滤杂质中的微塑料进入生态循环的问题。
收集组件570可拆卸地设置在污水接收装置500内部,以供用户将其取出进行手动清理。所述的过滤模块还设置有位置检测装置,可利用所述位置检测装置向洗涤设备反馈收集组件570的安装情况。在用户安装收集组件570不到位,或者在忘记安装收集组件570时,能够及时对用户进行提醒,避免洗涤设备直接运行洗涤程序,造成过滤杂质无法被收集组件570有效收集的情况。
实施例十二
本实施例提供一种上述实施例十一中所述洗涤设备的控制方法。如图15至图20所示,所述控制方法具体包括:
接收洗涤程序的启动指令;
若判断收集组件570已安装到位,则开始运行洗涤程序。
进一步地,若判断收集组件570未安装到位,则锁定洗涤设备,并发出报警信号。
需要说明的是,本实施例中所述的“收集组件570未安装到位”包括至少包括以下两种情况,即收集组件570已安装至容纳壳体510内部但安装不到位(如图19所示),以及容纳壳体510内部未安装收集组 件570(如图20所示)。
本实施例中,洗涤设备在接收到洗涤程序的启动指令之后,并不是直接开始运行,而是先对收集组件570的安装情况进行判断。只有在收集组件570已安装到位的情况下,才开始运行洗涤程序,确保洗涤过程中过滤装置600排出的污水可以准确地流入污水接收装置500的收集组件570处,并通过收集组件570实现污水中过滤杂质的收集。
而如果判断收集组件570的安装不到位,甚至并没有安装收集组件570时,洗涤设备可自动锁定,不运行洗涤程序,避免了无法有效收集过滤杂质的问题。洗涤设备还可以在判断收集组件570未安装到位时发出报警信号,从而及时提醒用户对收集组件570的安装腔情况进行手动检查,确保洗涤设备可以尽快开始运行。
本实施例中所述的报警信号可以是报警灯闪烁、蜂鸣音或语音提醒等多种形式,在此不做具体限定。
本实施例的具体方案中,所述过滤模块通过磁性件810与干簧管820的配合向洗涤设备反馈收集组件570的安装情况。干簧管820接入检测电路中,洗涤设备通过获取所述检测电路的通断状态,即可实现对收集组件570是否安装到位的判断。
具体地,洗涤设备接收洗涤程序的启动指令之后,获取所述检测电路的通断状态。若所述检测电路为导通状态,则判断收集组件570已安装到位;若所述检测电路为断开状态,则判断收集组件570未安装到位。
进一步地,本实施例的洗涤设备上设置有程序启动键,洗涤设备接收洗涤程序的启动指令具体是指:洗涤设备接收到所述程序启动键被触发的信号。
详细地,如图21所示,本实施例中所述洗涤设备的控制方法包括以下步骤:
S1、接收程序启动键被触发的信号;
S2、获取检测电路的通断状态,判断检测电路是否为导通状态;
S3、若检测电路为导通状态,则判断收集组件已安装到位,洗涤设备开始运行洗涤程序,否则,判断收集组件未安装到位,并执行步骤S4;
S4、锁定洗涤设备,发出报警提示信息。
本实施例的进一步方案中,洗涤设备判断收集组件570未安装到位后,若检测到容纳壳体510被拉出并再次推入箱体10中,则再次获取检测电路的通断状态,对收集组件570的安装情况进行判断。
具体地,如图22所示,在上述步骤S4之后还包括以下步骤:
S5、检测容纳壳体被拉出箱体,停止发出报警提示信息;
S6、检测容纳壳体被推入箱体,洗涤设备解除锁定,返回至步骤S2。
在上述方案中,当洗涤设备检测到容纳壳体510被拉出并再次推入箱体10中时,说明用户已重新对收集组件570的安装进行了调整,此时可再次检测收集组件570的安装情况,若已安装到位,就可以自动开始运行洗涤程序,无需用户再次手动启动洗涤程序,方便操作。
更进一步地,若洗涤设备连续N次获取所述检测电路均为断开状态,则保持洗涤设备持续处于锁定状态,并取消洗涤程序的运行,洗涤设备发出提示用户对污水接收装置500整体进行检测的报警信息。
在上述方案中,若用户多次调整收集组件570的安装位置后,洗涤设备获取检测电路仍处于断开状态,那么可能是干簧管820、收集组件570等结构本身出现了损坏,导致无法实现对收集组件570安装到位的检测。此时由于无法准确判断收集组件570是否能够实现对过滤杂质的收集功能,洗涤设备不运行洗涤程序,并提示用户进行检修。
本实施例中,洗涤设备开始运行洗涤程序之前,先通过位置检测装置获取收集组件570的安装状态,只有在收集组件570已安装到位时,才开始运行洗涤程序,否则锁定洗涤设备不运行洗涤程序,保证了收集组件570可以在洗涤设备运行过程中有效地收集过滤杂质,防止微塑料随过滤杂质排出洗涤设备。
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。
