Description

一种滚筒洗衣机 技术领域
本发明涉及衣物洗涤设备技术领域，具体地，涉及一种滚筒洗衣机。
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进水结构和/或排水结构，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。

本发明的滚筒洗衣机内筒为筒壁上不开设脱水孔的无孔内筒，洗涤时，内筒内盛放洗涤水，内筒转动进行衣物洗涤。本发明的滚筒洗衣机可以取消外筒，这样，在机体尺寸不变的情况下以增加内筒的容积，增大滚筒洗衣机的容量。另外，内筒内盛水，解决了现有洗衣机的洗涤水进入到内筒与外筒之间，随着时间的累积，内筒的外壁和外筒的内壁容易“藏污纳垢”的问题。
由于滚筒洗衣机是通过内筒转动提升/摔打衣物实现洗涤的，现有滚筒洗衣机外筒的作用主要是用于盛水，由于外筒固定不动，一般通过外筒与机体密封连接实现密封。本发明的滚筒洗衣机创造性的将内筒设计成无孔内筒，由于内筒是水平放置，本实施例内筒的投放口端与门体可相对转动的密封连接，保证了内筒的密封性，实现了内筒4的盛水功能，同时不影响内筒转动实现洗涤、脱水功能。
本发明的滚筒洗衣机的内筒同时作为盛水筒和洗涤筒，由于内筒进行转动，本发明的滚筒洗衣机为了实现内筒的进水，还包括进水装置，进水装置包括与外部水源连接的第一进水管、设置在门体上与第一进水管相对的集水槽及设置在门体内连通集水槽与内筒内部的第二进水管。
本发明的滚筒洗衣机根据门体与内筒密封连接的结构特点，由门体内部实现进水，另外，由于门体需要开关闭以取放衣物，本发明通过门体进水还需要不影响到门体的开闭，因此，本发明在门体上与第一进水管相对的集水槽，这样，进水由第一进水管进入到集水槽内，再由第二进水管进入到内筒内部。本发明通过在门体上设置集水槽，这样，可接住第一进水管的进水，实现了内筒的进水，同时不会影响到门体的正常开闭。

具体实施方式
下面结合附图对本发明的一种滚筒洗衣机进行详细描述：
如图1、图2、图3及图4所示，本实施例的一种滚筒洗衣机，包括机体7、门体和内筒4，所述的内筒4可转动的设置在机体7内，内筒4在洗涤过程盛水；所述内筒4的前部设置用于取放衣物的投放口，所述门体可开启/关闭的安装在机体7的前部且对应内筒4的投放口；所述内筒4的投放口端与门体可相对转动的密封连接。
本实施例的滚筒洗衣机内筒4为筒壁上不开设脱水孔的无孔内筒，洗涤时，内筒4内盛放洗涤水，内筒4转动进行衣物洗涤。本实施例的滚筒洗衣机可以取消外筒，这样，在机体尺寸不变的情况下以增加内筒4的容积，增大滚筒洗衣机的容量。另外，内筒4内盛水，解决了现有洗衣机的洗涤水进入到内筒与外筒之间，随着时间的累积，内筒的外壁和外筒的内壁容易“藏污纳垢”的问题。
由于滚筒洗衣机是通过内筒4转动提升/摔打衣物实现洗涤的，现有滚筒洗衣机外筒的作用主要是用于盛水，由于外筒固定不动，一般通过外筒与机体密封连接实现密封。本实施例的滚筒洗衣机创造性的将内筒4设计成无孔内筒，由于内筒4是水平放置，本实施例内筒4的投放口端与门体可相对转动的密封连接，保证了内筒4的密封性，实现了内筒4的盛水功能，同时不影响内筒4转动实现洗涤、脱水功能。
本实施例的滚筒洗衣机的内筒4同时作为盛水筒和洗涤筒，由于内筒4进行转动，本实施例的滚筒洗衣机为了实现内筒4的进水，还包括进水装置，进水装置包括与外部水源连接的第一进水管24、设置在门体上与第一进水管24相对的集水槽23及设置在门体内连通集水槽23与内筒4内部的第二进水管21。
本实施例的滚筒洗衣机根据门体与内筒4密封连接的结构特点，由门体内部实现进水，另外，由于门体需要开关闭以取放衣物，本实施例通过门体进水还需要不影响到门体的开闭，因此，本实施例在门体上与第一进水管24相对的集水槽23，这样，进水由第一进水管24进入到集水槽23内，再由第二进水管21进入到内筒内部。本实施例通过在门体上设置集水槽，这样，可接住第一进水管24的进水，实现了内筒4的进水，同时不会影响到门体的正常开闭。
作为本实施例的一种优选实施方式，本实施例所述的机体7上对应内筒的投放口开设开口，所述的门体包括外门18和内门19，内门19可转动的安装在外门18上，门体关闭时， 外门18可密封关闭机体上的开口，内门19与内筒4密封连接，这样，可实现本实施例滚筒洗衣机的内筒4相对门体的可转动密封连接。
进一步地，由于外门18固定不动，本实施例所述的集水槽23设置在外门18的顶部。
具体地，本实施例所述的外门18包括位于机体7外部覆盖在开口上的外门盖和伸入到机体的开口内的外门体，所述外门体的顶部侧壁局部向下凹陷形成集水槽23，所述的第一进水管24的出水端位于集水槽23的正上方。
由于滚筒洗衣机工作时，不可避免的会造成内筒4的震动，而本实施例的内筒4由于门体密封连接，因此，考虑到内筒4的震动问题，本实施例所述的外门18内侧通过减震装置连接一轴体17，所述的内门19通过轴承27可转动的安装在轴体17上。
具体地，本实施例所述的减震装置包括减震弹簧15和连接板20，多个减震弹簧15安装在外门18的内侧，减震弹簧15的另一端均连接至连接板20，连接板20与轴体17固定连接；所述的内门19的外侧中心固定一轴承座16，所述的轴承27安装在轴承座16内且与轴体17过盈配合。
与此同时，本实施例所述轴体17的内部中空，第二进水管21的一端与集水槽23连通，另一端通过轴体17通入到内筒4内部。
作为本实施例的一种优选实施方式，本实施例所述外门18的侧壁与内门19的侧壁之间通过弹性密封套26连接，弹性密封套26的一端与外门18的侧壁密封固定连接，弹性密封套26的另一端与内门19的侧壁保持密封接触；所述的外门18、弹性密封套26和内门19之间围合成一封闭空腔，所述的第二进水管21设置在该封闭空腔内。
本实施例的减震装置、轴体及轴承等部件均设置在密封空腔内，具有更好的密封性。
本实施例所述的进水装置还包括水盒1，所述的第一进水管24与水盒1之间通过第一连接软管25连通，第二进水管21与集水槽23之间通过第二连接软管22连通。
本实施例的水盒1连接第三进水管2，第三进水管2连接水龙头，以将自来水接入到水盒1内。
为了实现本实施例的滚筒洗衣机的排水，本实施例的滚筒洗衣机还包括外筒5，外筒5的前端固定在机体7的内壁上，所述的内筒4可转动的设置在外筒5内，内筒4的侧壁上设置离心阀11。
本实施例的离心阀11包括阀塞和弹簧，如图3及图4所示，离心阀的阀塞在未受到离心力时在弹簧的弹力作用下保持常闭状态，当内筒达到一定转速，离心阀塞受到离心力作用自动开启，从而实现排水。
本实施例利用离心阀11的工作原理，通过控制内筒4的转动从而控制其排水。
具体地，本实施例的滚筒洗衣机洗涤时，离心阀11关闭，内筒4内盛水，内筒4与外筒5之间无水，脱水时，离心阀11开启，洗涤水由离心阀11排放至内筒4与外筒5之间并由外筒5排出。当然，也可以在洗涤过程中通过控制内筒4高速转动打开离心阀11实现排水。
作为本实施例的一种优选实施方式，所述内筒4的投入口端的直径小于内筒底的直径，所述内筒4的侧壁由投入口端向内筒底倾斜向上设置；所述的离心阀11包括多个，沿着内筒靠近内筒底的侧壁一周均匀分布。内筒4的结构设计以及离心阀11的分布方式可以更好的有利于洗涤水在高速离心作用下排出。
本实施例的外筒5上对应离心阀位置开设外筒排水口，外筒排水口连接主排水管12，主排水管12连接排水阀13。
本实施例的外筒5的前端固定在机体7的内壁上，为了实现内筒4的减震，本实施例的滚筒洗衣机还包括中心转轴9、驱动装置10和支撑减震装置，所述的内筒4通过中心转轴9与驱动装置10传动连接；所述支撑减震装置包括支撑架6、减震挂簧3和减震器14，所述支撑架6的一端套设在中心转轴9上并通过轴承与中心转轴9支撑连接，另一端延伸至外筒5的外围用于安装挂簧3和减震器14。
本实施例的滚筒洗衣机还可通过以下实施方式解决排水的问题，具体方案如下：
本实施例滚筒洗衣机的中心转轴9内部中空以设置用于排水的水流流道，本实施方式可取消离心阀的使用。
本实施例将水流流道设置在中心转轴9内，这样，洗衣机的排水可以由此水流流道进出，内筒转动不会影响进排水。
作为本发明的一种优选实施方式，所述中心转轴9的一端伸出至驱动装置10外部，中心转轴9的伸出端通过轴承可转动的安装在连通件上，所述的连通件内具有连通通道，所述的连通通道连通水流流道与进水装置/排水装置。
本发明以通过中心转轴9内的水流流道实现排水为例进行详细阐述，本实施例的中心转轴9内的水流流道与排水装置连通，以实现排水功能。具体地，本实施例所述的排水装置包括排水管和自吸泵，自吸泵的进水口通过排水管与中心转轴内的水流流道连通。
由于中心转轴9位于内筒4的筒底中心位置，并非出于内筒的最低位置，因此，为了保证内筒4内的洗涤水更好的排出，所述内筒4的后筒底内壁设置用于在脱水和/或排水过程中集水的集水装置，集水装置与水流流道连通；在脱水和/或排水过程中，集水装置将内 筒内的水收集并在自吸泵的吸力作用下排出。
具体地，本实施例所述的集水装置具有集水腔室和集水流道，所述的集水腔室设置在内筒4的后筒底内壁中心且与中心转轴9内的水流流道相连通，所述的集水流道设置在内筒的后筒底内壁，集水流道的一端与集水腔室连通，另一端朝向内筒4的内壁延伸。
优选地，所述的集水流道包括多个，分别沿着内筒4后筒底的周向均匀分布。
为了配合集水装置进行集水，本实施例的内筒4上与后筒底相对的一端为前筒盖，所述前筒盖的直径小于后筒底的直径，所述内筒4的侧壁由前筒盖向后筒底倾斜向上设置。
为了实现集水装置的集水效果，还需要配合内筒4的转动，内筒4转动，洗涤水在离心作用下聚集在内筒4的侧壁表面，由由于侧壁的倾斜结构，使得洗涤水沿着内筒4的倾斜侧壁由前筒盖向后筒底汇聚并由设置在此的集水流道引入到集水腔室内。
因此，本实施例的滚筒洗衣机脱水过程中借助内筒4的高速转动实现集水排水，洗涤过程后的排水可以增加排水程序，通过提高内筒4高速转动实现排水。
作为本实施例的一种优选实施方式，本实施例所述的集水装置包括盖板，盖板安装在内筒的后筒底内壁上：所述的盖板内部具有封闭的中空腔室以形成集水腔室和集水流道，或者，所述的盖板内部具有开口的凹槽，盖板与内筒的后筒底内壁之间密封连接将凹槽封闭，形成集水腔室和集水流道。
作为本实施例的一种优选实施方式，所述集水装置的上表面构造有凸出于内筒内的底部的凸起结构，凸起结构可在洗涤时对洗涤物进行提升，从而提高洗衣效果。
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。
