Description

一种洗衣机的排水结构及排水方法 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，特别涉及一种洗衣机的排水结构，还涉及一种洗衣机的排水方法。
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，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；同时，由于洗衣机不设外筒、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，提供一种洗衣机的排水结构。本发明所述的洗衣机排水结构，通过在内筒大口端设置自外周向中心流动的排水流道，使内筒中高速旋转时，内筒中水在离心力作用下向大口端汇聚流动并沿排水流道自内筒大口端中心排出，以解决内筒中盛放洗涤水排放的问题，进而实现了对可旋转内筒筒口进行密封、洗衣机正常工作过程时内筒中进水并不外泄、洗衣机排水时内筒中洗涤水经排水水路外排的目的； 同时，将滚筒洗衣机的内外筒合二为一，以实现洗衣机扩展洗涤容量的目的。
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：
一种洗衣机的排水结构，洗衣机壳体内安装有内筒，内筒为一端直径小、一端直径大的锥形筒，内筒大口端设有排水流道，排水流道的一端与内筒的大口端相连通、另一端经大口端中心穿出内筒并与洗衣机排水管相连通。
进一步，内筒为自开口向内筒底逐渐增大直径的锥形筒，内筒底中心经转轴安装于内筒支撑件上；排水流道设置于内筒底内侧面，排水流道的一端设于内筒底与内筒侧壁相交处、另一端自内筒底中心穿出并沿轴线穿过电机轴，排水流道的穿出端与洗衣机排水管相连通。
进一步，内筒底上设有多条排水流道，各排水流道的一端等间隔角度的均布于内筒底外周并与内筒内部相连通、另一端交汇于内筒底中心并自内筒底中心穿出与洗衣机排水管相连通。
进一步，至少一条排水流道的一端设于内筒底中部并与内筒内部相连通、另一端自内筒底中心穿出并与洗衣机排水管相连通；
优选的，相邻排水流道的端部交错设置于内筒底的中部或外周部。
进一步，各排水流道由凸出于内筒底内侧面的中空凸筋构成，在内筒旋转过程中中空凸筋对内筒中水流和衣物进行提升、摔打，以对衣物进行洗涤。
进一步，所述排水流道和/或排水管上设有排水泵，以对流至洗衣机内筒底处的水流施加压力沿排水流道、排水管外排至洗衣机外部。
本发明的另一重要目的在于，提供一种应用上述洗衣机的排水方法，以解决具有盛水、旋转双重功效内筒的洗衣机如何进行工作时密封、内筒中洗涤水外排的问题。
为了实现上述发明目的，其采用的具体技术方案如下：
一种应用于上述任一所述洗衣机的排水方法，内筒以一定转速旋转，使内筒中洗涤水在离心力作用下贴锥形内筒内壁向大口端流动，水流至内筒大口端时沿大口端设置的排水流道自内筒大口端中心流出，并沿排水管流出洗衣机，实现内筒中洗涤水外排。
进一步，具体排水步骤如下，
步骤1、洗衣机内筒以一定转速旋转，内筒中水流在离心力作用下流动至与内筒侧壁贴 合处；
步骤2、在锥形内筒的作用下，使得贴内筒侧壁的水流受内筒侧壁的引导、内筒旋转过程中离心力的作用，令内筒中的水流向直径较大的内筒底；
步骤3、流动至内筒底处的水流入内筒底上所设排水流道中，并沿排水流道自内筒中心处流出内筒，再沿排水管排出洗衣机。
进一步，在上述步骤3中，排水流道和/或排水管上的排水泵开始工作，以对流至内筒底处的水流施加压力，令水沿排水流道、排水管流动并排至洗衣机外部。
进一步，在洗衣机排水过程中，内筒以中高速转动，以使得内筒中水受离心力作用贴合内筒侧壁、并向内筒大口端流动。
本发明所述的洗衣机和现有技术的洗衣机相比具有下列有益效果：
通过上述设置及方法，使得在洗衣机正常洗涤状态下内筒中水流不受离心力作用、并不向内筒大口端汇聚流动，洗衣机排水状态下内筒高速旋转内筒中水流受离心力作用、向内筒大口端排水流道流动并外排，使得内筒正常旋转时内筒中盛水不会自排水口流出，进而实现了内筒旋转过程中内筒密封、排水时内筒中水流被离心力挤压入排水流道使内筒中盛水正常外排的效果,达到了内筒旋转和盛水双重功效的洗衣机正常排水的目的；同时，使得内筒外部可不需再套装外筒，增大了内筒的容积，提高了洗衣机的洗涤容量。
为了使本发明的技术方案的设计构思更加清楚，便于进一步理解其带来的有益效果，下面结合附图对本发明的部分具体实施方式作详细的描述。

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。

如图1所示，本发明实施例中介绍了一种洗衣机，洗衣机包括壳体2，壳体2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101、后端为密封设置的内筒底102；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2前端安装有可向外打开的门盖4，以在门盖4闭合后封闭内筒筒口101、打开门盖4后自内筒筒口101向内筒1中投放衣物的目的。内筒1后端经内筒支撑件3安装于洗衣机壳体2内，所述的内筒支撑件3与内筒1后端同轴设置，内筒支撑件3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6和减震支撑杆7与洗衣机壳体2相连接，以实现内筒支撑件3可震动得安装于洗衣机壳体2内的目的；同时，内筒底102中心与洗衣机驱动电机5的电机轴同轴设置，以驱动内筒1旋转，内筒1和驱动电机5均固定安装于内筒支撑件3上。优选的，内筒底102与驱动电机5分别设置与内筒支撑件3的两侧，驱动电机5于内筒支撑件3相固定连接，驱动电机5的电机轴经轴承穿过内筒支撑件3并与内筒底102同轴固定连接，且驱动电机5轴可相对内筒支撑件3旋转，以实现内筒1和驱动电机5安装于内筒支撑件3上、并令内筒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。
本发明实施例中为了将洗衣机内筒中进水外排，并实现洗衣机工作过程中内筒密封盛水进行正常洗涤，进行如下设置：
一种洗衣机的排水结构，洗衣机壳体2内安装有内筒1，内筒1为一端直径小、一端直 径大的锥形筒，内筒1大口端设有排水流道32，排水流道32的一端与内筒1的大口端相连通、另一端经大口端中心穿出内筒1并与洗衣机排水管31相连通。
本发明实施例中还介绍了一种洗衣机的排水方法，内筒以一定转速旋转，使内筒中洗涤水在离心力作用下贴锥形内筒内壁向大口端流动，水流至内筒大口端时沿大口端设置的排水流道自内筒大口端中心流出，并沿排水管流出洗衣机，实现内筒中洗涤水外排。
滚筒洗衣机在正常洗涤过程中，内筒1一般以低速进行旋转，内筒1中水并不会受到太多的离心力作用，使得内筒1中衣物和水流随着内筒低速旋转而产生摔打洗涤效果，令内筒1中水流并不会向大口端汇聚流动、也不会外排出洗衣机；而当滚筒洗衣机在排水过程中，内筒1以中高速旋转，内筒1中水受内筒旋转离心力作用，使得内筒1中水流贴内筒壁向内筒大口端汇聚流动，并流入内筒大口端所设排水流道32、经内筒大口端中心流出内筒1并自排水管31排出洗衣机。
通过上述设置，使得在洗衣机正常洗涤状态下内筒中水流不受离心力作用、并不向内筒大口端汇聚流动，洗衣机排水状态下内筒高速旋转内筒中水流受离心力作用、向内筒大口端排水流道流动并外排，使得内筒正常旋转时内筒中盛水不会自排水口流出，进而实现了内筒旋转过程中内筒密封、排水时排水阀打开内筒中盛水正常外排的效果,达到了内筒旋转和盛水双重功效的洗衣机正常排水的目的；同时，使得内筒外部可不需再套装外筒，增大了内筒的容积，提高了洗衣机的洗涤容量。

本实施例中，各排水流道32由凸出于内筒底102内侧面的中空凸筋构成，在内筒1旋转过程中中空凸筋对内筒1中水流和衣物进行提升、摔打，以对衣物进行洗涤，以使得向内凸出的排水流道32具备了对内筒1中衣物进行提升、摔打洗涤的辅助提升筋功能。
本实施例中，所述排水流道32和/或排水管31上设有排水泵33，以对流至洗衣机内筒底102处的水流施加压力沿排水流道32、排水管31外排至洗衣机外部，排水泵33在滚筒洗衣机处于正常洗涤状态时不工作、滚筒洗衣机执行排水程序时打开，以实现对洗衣机内筒中水流外排进行操控、并提供水流驱动力。
实施例二
本实施例中介绍了一种基于上述实施例一所述洗衣机的排水方法，内筒以一定转速旋转，使内筒中洗涤水在离心力作用下贴锥形内筒内壁向大口端流动，水流至内筒大口端时沿大口端设置的排水流道自内筒大口端中心流出，并沿排水管流出洗衣机，实现内筒中洗涤水外排。
通过上述方法，使得在洗衣机正常洗涤状态下内筒中水流不受离心力作用、并不向内筒大口端汇聚流动，洗衣机排水状态下内筒高速旋转内筒中水流受离心力作用、向内筒大口端排水流道流动并外排，使得内筒正常旋转时内筒中盛水不会自排水口流出，进而实现了内筒旋转过程中内筒密封、排水时排水阀打开内筒中盛水正常外排的效果,达到了内筒旋转和盛水双重功效的洗衣机正常排水的目的。
本实施例中，所述洗衣机排水方法的具体排步骤如下，
步骤1、洗衣机内筒以一定转速旋转，内筒中水流在离心力作用下流动至与内筒侧壁贴合处；

步骤3、流动至内筒底处的水流入内筒底上所设排水流道中，并沿排水流道自内筒中心 处流出内筒，再沿排水管排出洗衣机。
本实施例中，在上述步骤3中，排水流道和/或排水管上的排水泵开始工作，以对流至内筒底处的水流施加压力，令水沿排水流道、排水管流动并排至洗衣机外部。而在洗衣机执行其他程序时，排水流道和/或排水管上的排水泵并不工作，使得内筒中的水并不会被排水泵吸附外排，令内筒中水留存、对衣物进行正常洗涤。
本实施例中，在洗衣机排水过程中，内筒以中高速转动，以使得内筒中水受离心力作用贴合内筒侧壁、并向内筒大口端流动。
实施例三

通过上述设置，以实现内筒筒口处被弹力压紧的内筒盖密封，洗衣机洗涤过程中内筒盖与内筒筒口相密封接触并共同旋转、进而达到内筒旋转时筒口动密封的目的，使得内筒具备旋转和盛水的双重功能；同时，使得内筒外部可不需再套装外筒，增大了内筒的容积，提高了洗衣机的洗涤容量。
本实施例中，门盖4与内筒盖8同轴设置，门盖4与内筒盖8之间经弹力机构相连接，以令门盖4闭合后内筒盖8在处于压缩状态的弹力机构作用下压紧于内筒筒口101处。

优选的，本实施例中，为了在内筒盖8扣合后，增大内筒盖8与内筒筒口101之间的密封性，可将内筒盖8与内筒筒口101之间相弹性卡接，以在门盖4闭合后令内筒盖与内筒筒口101相固定卡接、在门盖4打开后令内筒盖随门盖4一起移动并与内筒筒口101相脱离，实现内筒盖8与内筒筒口101相密封接触处进行卡接固定、以增强内筒筒口101密封性的目的。
本实施例中，内筒盖8的中心处连接有沿内筒1轴线方向向内筒外部延伸的转轴12，内 筒盖8可绕转轴旋转。转轴12一端与内筒盖8可旋转的相连接，另一端经弹力机构与门盖4相连接，弹力机构对内筒盖8施加一弹力，驱动内筒盖8向内筒筒口101方向移动，以使内筒盖8密封扣合于内筒筒口101处，实现内筒筒口101的密封。

通过将内筒盖与门盖之间经加装有弹簧的转轴相连接，以使得门盖闭合后，内筒盖与内筒筒口相接触压缩弹簧，使弹簧对内筒盖提供一向内筒方向移动的弹力，令内桶盖与内筒筒口相密封贴合，进而实现了门盖闭合后限制内筒盖、内筒盖与内筒筒口相密封接触的目的；同时，由于内筒盖与转轴之间可相对旋转，使得内筒在洗衣机驱动电机带动下进行旋转时，内筒盖可在摩擦力作用力随内筒共同旋转，以实现内筒筒口处进行密封处理的目的；还有，由于内筒前端经内筒盖、转轴、弹簧与门盖相连接，使得内筒前端可震动得弹性安装与洗衣机壳体内，令内桶前端与洗衣机壳体相支撑安装，提高了内筒的支撑作用点，增强了内筒运转过程中的平稳性。

本实施例中，内筒盖8的外周处设有一圈向外倾斜的倾斜部15，所述倾斜部15为自内筒1外周向门盖4方向逐渐增大直径的锥形面；内筒筒口101处设有与倾斜部15相对应贴合接触的一圈固定部16；优选的，固定部16的外端设有向外弯曲的倒角，以引导内筒盖8滑入内筒筒口101中、使固定部16与倾斜部15相对应贴合实现密封。
进一步优选的，内筒盖8的外周设有两段不同曲率的、均向门盖4方向逐渐增大直径的锥形面，第一锥形面的两侧分别与门盖4外周和第二锥形面一侧相连接；第一锥形面与内筒筒口101的水平弯折面相对应，水平弯折面为自内筒筒口101处向内筒1外部水平弯折的圆筒面，水平弯折面的内径与第一锥形面的最大直径相等或稍小设置；水平弯折面的端部逐渐向外倾斜以构成锥形的固定部16，第二锥形面构成倾斜部15、与固定部16相对应贴合接触。
本实施例中，内筒盖8与门盖4之间还设有管状的、可沿径向伸缩的密封管14，密封管14的一端与门盖4的外周处相密封连接、另一端与门盖4相固定连接，以令弹力机构密封安装于密封管14内部、随着密封管14的伸缩使内筒盖8可相对门盖4产生相对移动；所述的密封管14为由弹性橡胶材质的波纹管构成。优选的，密封管14的端部与门盖4可绕内筒1轴线相对旋转的套接，以使门盖4随内筒1共同旋转时密封管14不会共同旋转。
实施例四
本实施例与上述实施例一和二的区别在于：洗衣机采用上述排水结构和排水方法控制洗衣机脱水，以将洗衣机内筒中的衣物脱离的水流经上述结构和方法外排部洗衣机，实现对无孔内筒衣物进行脱水处理的目的。
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。

  4. 根据权利要求3所述的一种洗衣机的排水结构，其特征在于，至少一条排水流道的一端设于内筒底中部并与内筒内部相连通、另一端自内筒底中心穿出并与洗衣机排水管相连通。
  5. 根据权利要求3所述的一种洗衣机的排水结构，其特征在于，各排水流道由凸出于内筒底内侧面的中空凸筋构成，在内筒旋转过程中中空凸筋对内筒中水流和衣物进行提升、摔打，以对衣物进行洗涤。
  6. 根据权利要求1至5任一所述的一种洗衣机的排水结构，其特征在于，所述排水流道和/或排水管上设有排水泵，以对流至洗衣机内筒底处的水流施加压力沿排水流道、排水管外排至洗衣机外部。
  7. 一种应用于上述权利要求1至6任一所述洗衣机的排水方法，其特征在于：内筒以一定转速旋转，使内筒中洗涤水在离心力作用下贴锥形内筒内壁向大口端流动，水流至内筒大口端时沿大口端设置的排水流道流出内筒，并沿排水管流出洗衣机，实现内筒中洗涤水外排。
  8. 根据权利要求7所述的一种洗衣机的排水方法，其特征在于，具体排水步骤如下，
    步骤1、洗衣机内筒以一定转速旋转，内筒中水流在离心力作用下流动至与内筒侧壁贴合处；
    步骤2、在锥形内筒的作用下，使得贴内筒侧壁的水流受内筒侧壁的引导、内筒旋转过程中离心力的作用，令内筒中的水流向直径较大的内筒底；
    步骤3、流动至内筒底处的水流入内筒底上所设排水流道中，并沿排水流道自内筒中心处流出内筒，再沿排水管排出洗衣机。
