Description

一种内筒及免清洗洗衣机 技术领域
本发明属于洗衣机技术领域，具体涉及一种仅设可旋转、可盛水内筒的洗衣机，还涉及一种应用于上述洗衣机的内筒。
背景技术
现有技术中，滚筒洗衣机一般包括相互套装的内筒和外筒，外筒密封用于盛水，内筒用于盛放衣物、经旋转内筒以对衣物进行摔打洗涤；同时，内筒上设置脱水孔，以使得外筒中的水经脱水孔流入内筒以对内筒中的衣物进行浸泡、内筒中的水经脱水孔流出至外筒、内筒中衣物上水分在内筒高速旋转时经脱水孔外排至外筒，以实现对衣物进行洗涤的目的。
但是，由于内筒与外筒相互套装，在洗衣机使用过程中内外筒之间容易积存污垢；同时，由于内外筒相互套装，用户无法对内筒外壁、外筒内壁进行清洁，使洗衣机内部细菌增多，降低了洗衣机的洗衣效率、衣物洗涤后的洁净度。
同时，上述现有洗衣机中，由于内筒外部套装有外筒，洗衣机的洗涤过程是通过内筒旋转对衣物进行摔打洗涤，使得洗衣机的洗涤容量是以内筒为基准，令洗衣机的内部空间使用率较低，无法在现有基础上对洗衣机洗涤容量进行扩展。
有鉴于此，如何设置一种洗衣机，以将内外筒合一、或者直接设置封闭内筒，令内筒设置为密封容器，既能盛水和衣物，又能旋转对衣物进行摔打进行洗涤，还避免了洗涤水流在内外筒之间流动还需对内外筒之间进行清洗的问题；同时，由于还可以在洗衣机上不设外筒、或外筒与洗衣机壳体一体设置，还能使洗衣机的内筒扩大、以扩展洗衣机的洗涤容量，就成为了研发热点。
但是，由于内筒不仅用于盛放洗涤水，还要旋转以对筒内衣物进行摔打清洗，因此如何设置一种适用于上述洗衣机的脱水结构和排水结构，就成为了急需解决的难题。
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，以实现内筒同时具备容纳洗涤水和搅动衣物的双重功能。本发明还涉及一种内筒，以达到引导内筒中洗涤水向内筒底所设导水流道汇聚流动、进而提升洗涤水排水效率的目的。
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：

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附 图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至图9所示，本发明实施例中介绍了一种洗衣机，洗衣机包括壳体，壳体内设有内筒1，内筒1轴线水平延伸或自前向后逐渐向下倾斜设置，内筒1前端为开口设置的内筒筒口、后端为密封设置的内筒底；内筒1筒壁上不设通孔，以使得内筒1内部构成仅前部开口设置的密封容器。同时，洗衣机壳体前端安装有可向外打开的门盖，以在门盖闭合后封闭内筒筒口、打开门盖后自内筒筒口向内筒1中投放衣物的目的。内筒1后端经内筒支撑件安装于洗衣机壳体内，所述的内筒支撑件与内筒1后端同轴设置，内筒支撑件的上下两端分别向内筒1前端筒口方向弯折，弯折部至少延伸至内筒1中部，上下弯折部分别经减震吊簧和减震支撑杆与洗衣机壳体相连接，以实现内筒支撑件可震动得安装于洗衣机壳体内的目的；同时，内筒底中心与洗衣机驱动电机的电机轴同轴设置，以驱动内筒旋转，内筒和驱动电机均固定安装于内筒支撑件上。优选的，内筒底与驱动电机分别设置与内筒支撑件的两侧，驱动电机与内筒支撑件相固定连接，驱动电机的电机轴经轴承穿过内筒支撑件并与内筒底同轴固定连接，且驱动电机轴可相对内筒支撑件旋转，以实现内筒1和驱动电机安装于内筒支撑件上、并令内筒1可独自在驱动电机作用下进行旋转对内部衣物进行洗涤的目的。
还有，本发明实施例中的洗衣机可以为现有技术中任一具备门盖闭合内筒筒口后内筒构成密封容器的洗衣机，以在洗衣机执行脱水程序时，控制内筒高速旋转，以将内筒中自衣物脱离的水流顺利外排出内筒，进而达到对无孔内筒洗衣机正常执行脱水程序的目的。因此，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，采用现有普通洗衣机，只需将洗衣机内筒1设置为没有脱水孔、门盖闭合内筒筒口后形成密封容器的洗衣机。当然，还可以在洗衣机内筒筒口处单独设置一内筒盖，不需利用门盖就可对内筒盖进行独立操作，并利用内筒盖对内筒筒口进行密封闭合。同时，本发明实施例中的洗衣机还可以适用于顶开式洗衣机，在内筒侧壁上设置衣物投放口，并在内筒侧壁上设置可向外翻转开闭的、对应密封衣物投放口的门体，以在内筒停止旋转后定位至对应位置，令用户可对应打开门体，自衣物投放口向洗衣机内筒内部投放、或取出衣物。
同时，通过将内筒设置为门盖扣合后进行洗涤的密封容器，使得洗涤过程中衣物只与密封内筒中的洗涤水接触，避免了内外筒之间洗涤水流入内筒中污染衣物情况的发生，大大提高了洗衣机的洗涤洁净度，避免了内外筒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。
本发明实施例中介绍了一种免清洗洗衣机，洗衣机内筒1为内筒筒口被门盖扣合后密闭的容器，内筒底排布有多条自外周延伸至中心的导水流道，内筒底中心设有与各导水流道端部分别相连通的中心接头，中心接头的后端设有穿出内筒底的出水接口，出水接口与导水套筒第一端相连通，导水套筒第二端穿过驱动电机后与固定安装于内筒支撑件上的流水腔室相连通，流出腔室上所设出水接口与洗衣机排水管相连通，以在内筒高速旋转时将内筒中的洗涤水引导至内筒底处、并自内筒底外周的导水流道端部流出内筒、再沿导水套筒排出。
同时，本发明实施例中，洗衣机排水管上设有抽吸泵，抽吸泵工作后经管路作用于导水 流道与内筒连通处，使导水流道连通端形成负压，以将内筒中的洗涤水沿导水流道、中心接头、导水套筒、排水管流出，达到对洗衣机排水水流提供流动动力的目的。
本发明实施例中，为了实现内筒中洗涤水在离心力作用时向内筒底方向汇聚流动，将内筒设置为自前向后逐渐扩大筒径的锥形筒，令内筒底处为内筒的大口端，以在内筒高速旋转时，内筒中洗涤水受离心力作用而贴合内筒壁流动并沿锥形筒壁向内筒底方向汇聚流动。
通过上述设置，实现了利用内筒高速旋转时离心力引导内筒中洗涤水向内筒底所设导水流道外排的目的，以利用内筒高速旋转时对洗涤水可控外排、在内筒正常旋转洗涤时内筒中蓄水洗涤的双重效果；进而达到洗衣机执行脱水和/或排水程序时，内筒高速旋转的离心力作用于洗涤水自动沿导水流道外排后，沿导水套筒排出洗衣机的目的。
