Description

一种滚筒洗衣机 技术领域
本发明涉及洗衣设备技术领域，具体地，涉及一种滚筒洗衣机。
背景技术
洗衣机作为人们日常生活中使用最为广泛的一种家用电器，帮助人们摆脱了洗衣的烦恼，给人们带来了极大的便利。但是现有洗衣机一般都包括内筒和外筒，内筒的桶壁上分布多个脱水孔，而在洗涤过程中，内筒与外筒之间的洗涤水不会被利用，造成该部分洗涤水的浪费，且洗涤过程中产生的脏污会随着水流进入内筒与外筒之间而被积累，随着长时间的使用，脏污的累积会影响洗涤效果，降低用户使用体验。
为了解决洗衣机的节水问题，现在也提出了一些专利，比如专利号为201410215346.3，名称为一种滚筒洗衣机的中国发明专利，该发明涉及一种滚筒洗衣机，包括箱体，箱体内设有内筒和外筒，外筒与箱体之间设有门封，内筒与驱动装置相连，所述的内筒为无孔内筒，且所述的内筒为筒底处直径小、筒口处直径大的锥形筒，内筒的筒口处向内呈弧形收拢，所述的门封上设有进水导管，进水导管的一端与洗涤水快速加热装置相连，进水导管的另一端穿过门封伸入内筒内，所述的外筒上设有排水口及水压检测装置。由上述技术方案可知，该发明的内筒为无孔内筒，通过设置在门封上的进水导管实现内筒进水，并通过内筒自身的形状在脱水过程中实现排水，这样可以避免在内、外筒之间存水，大幅节约了洗涤用水量。
上述发明提供了一种具有无孔内筒的滚筒洗衣机，解决了内筒与外筒之间存水浪费和内筒与外筒之间积累脏污的问题，但是，仅仅是将现有滚筒洗衣机的内筒设计为无孔结构，现实意义很小，由于内筒既要旋转进行洗涤、脱水，又要盛水，如何实现具有无孔内筒的洗衣机排水便成为内筒无孔化所面临的首要难题。
有鉴于此，特提出本发明。

图2本发明实施例的滚筒洗衣机的剖视图(实施方式二)。
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所示，本实施例提供一种无孔内筒前开式结构的滚筒洗衣机，结构简单，能够无需在内筒与外筒之间填充洗涤/漂洗水而极大的减少了洗衣机的洗涤用水量。避免了内筒与外筒之间污垢附着的可能。极大的提高了用户健康及用户体验，极大的节约了水资源。
本实施例的滚筒洗衣机具有外壳1，外壳1包括：上台面板3，前面板，后背板和底板。底板上安装固定了底脚，用于支撑整个洗衣机。外壳1内部内筒8旋转，优选的是设置了提升筋11，不断的提升跌落摔打衣物，以便洗净衣物。内筒8是无孔结构的，与内筒8紧固连接的内筒轴20穿过所示轴承19并连接驱动电机23。内筒8前部筒口上安装可开启/闭合的内筒门9，进而实现内筒8为密封舱结构。
本实施例的外壳1上安装可开启/关闭的机门7。
进一步地，为了实现无孔内筒的排水，本实施例的一种滚筒洗衣机，包括：
内筒8，具有可独立盛放洗涤水的洗涤腔室；
内筒排水口16，设置在内筒8上；
排水密封装置，安装在内筒排水口16上控制其开闭；
集水装置6，具有收集内筒排水口16排出洗涤水的集水腔室。
本实施例的滚筒洗衣机针对无孔内筒的结构特点，内筒的筒壁上不再设置脱水孔，只设置固定的内筒排水口16，通过设置集水装置6针对内筒排水口16的排水进行收集即可，实现对内筒8内的洗涤水的排放收集，再由集水装置6将洗涤水排出，可取消现有内筒外设置的外筒，从根本上上杜绝了内筒与外筒之间藏污的可能，而且实现了节水。另外，针对同尺寸规格壳体的洗衣机，由于取消了外筒的设计，可以适当的增大内筒的容积，以洗涤更多的衣物，实现扩容的目的。
本实施例所述的排水密封装置包括：
离心件12，在离心力作用下产生离心运动；
密封柱塞15，用于封堵内筒排水口16；

优选地，所述的排水密封装置设置在提升筋11内，提升筋11上开设多个用于洗涤水进入的喷淋孔10，所述提升筋11上开设用于密封柱塞15穿出容纳腔室的柱塞过孔。
本实施例的密封柱塞15包括密封柱和密封塞，密封柱上套装用于为密封塞复位提供弹性力的弹性件13，所述的弹性件13为弹簧。
本实施例滚筒洗衣机的控制方法包括：洗衣机洗衣过程中，通过控制内筒转速达到或者超过设定转速N0，离心件12受到离心力产生离心运动带动密封柱塞15将内筒排水口16打开进行内筒排水。
作为本实施例的一种实施方式，洗衣机执行完洗涤程序或者漂洗程序后，控制内筒转速达到第一转速N1并维持一设定时间t1，所述的N1≥N0，N0大于洗涤程序或者漂洗程序中内筒的转速；当内筒保持转速N1转动时间达到t1时，控制内筒停止转动进入下一程序；
进一步地，洗衣机执行脱水程序，所述脱水程序中的最低脱水转速N2大于等于N0。
由内筒8的排水过程可知，内筒8需要高速转动实现离心排水，为了实现将内筒排水口16排出的水的收集，本实施例所述的集水装置6包括环形本体，环形本体位于内筒8的外周且与内筒8共轴线设置，所述的环形本体内部具有环形集水腔室28，所述的内筒排水口16与环形集水腔室28相连通。
本实施例的集水装置6具有环形集水腔室28，这样在内筒8不管转动到如何位置时，都能保证内筒排水口16排出的水被排放至环形集水腔室28内收集。
为了实现将内筒排水口16排出的水排入环形集水腔室28内，如图1所示，本实施例所述环形本体上开设连通环形集水腔室的环形开口27，所述内筒8的筒壁上设置排水水道14，所述排水水道14的一端连通内筒排水口16，另一端由环形开口27插入环形集水腔室28。优选地，所述的排水水道14设置在内筒8的内侧壁或者内筒8的外侧壁上。

优选地，所述内筒8的侧壁上位于筒口与环形本体之间的区域设置内筒排水口，所述的环形前端壁与内筒周壁间隔设置形成环形开口；所述环形后端壁与内筒的外周壁旋转密封连接。这样，可使得由排水水道14排入集水装置内的水由集水装置内甩出。
进一步地，作为本实施例的一种实施方式，所述的环形本体包括环形外侧壁，环形内侧壁，环形前端壁和环形后端壁，所述的环形外侧壁、环形内侧壁分别环绕内筒周壁一周设置，环形外侧壁位于环形内侧壁的外周，所述环形前端壁的一端连接环形外侧壁靠近内筒的筒口侧一端，另一端连接环形内侧壁靠近内筒的筒口侧一端，所述环形后端壁的一端连接环形外侧壁靠近内筒的筒底侧一端，另一端连接环形内侧壁靠近内筒的筒底侧一端；
所述内筒的侧壁上位于筒口与环形本体之间的区域和/或筒底与环形本体之间的区域设置内筒排水口，所述的环形开口开设在环形前端壁和/或环形后端壁上。
本实施例的集水装置内形成一个只具有环形开口27的环形密封腔室，杜绝了排水水道14排入集水装置内的水被甩出。
为了实现将内筒排水口16排出的水排入环形集水腔室28内，如图2所示，作为本实施例的另一种实施方式，所述内筒8的周壁上设置多个内筒排水口16，所有内筒排水口16处于或者大致处于同一圆周上；所述环形本体上靠近内筒8一侧开设连通环形集水腔室28的环形开口27，环形开口27包围所有内筒排水口设置。
具体地，本实施例所述的环形本体包括环形侧壁，环形前端壁和环形后端壁，所述的环形侧壁环绕内筒周壁一周设置，所述环形前端壁的一端连接环形侧壁靠近内筒的筒口侧一端，另一端沿着内筒的径向向内筒侧延伸，所述环形后端壁的一端连接环形侧壁靠近内筒的筒底侧一端，另一端沿着内筒的径向向内筒侧延伸；
所述环形前端壁靠近内筒一侧与环形后端壁靠近内筒一侧之间敞口设置形成环形开口27。
为了防止排进集水装置内的水溅出，本实施例所述的环形前端壁和环形后端壁分别与内筒的外周壁旋转密封连接。
为了实现将集水装置内收集的水排出，本实施例的集水装置的环形本体上开设排水口，所述的排水口连接排水管路17，所述排水管路17上设置控制其通断的排水控制装 置18，所述的排水控制装置为排水阀或者排水泵。
进一步地，本实施例所述的滚筒洗衣机还包括与内筒共中心轴线设置的安装盘26，所述的安装盘26设置在内筒8的筒底底部。
优选地，所述滚筒洗衣机还包括驱动电机23，驱动电机23安装在所述安装盘26上。
优选地，所述的集水装置6通过连接件固定在安装盘26上，或者，所述的集水装置6与安装盘26一体成型。
本实施例的滚筒洗衣机还包括进水管支架24，进水管支架24一端安装在安装盘26上，一端支撑进水管25。
为了实现向本实施例的无孔内筒内进水，本实施例的滚筒洗衣机包括驱动电机23和内筒轴20，所述的驱动电机23通过内筒轴20与内筒8传动连接带动内筒8转动，所述的内筒轴20内具有连通内筒8内部的中空通道21，洗衣机的进水管路与内筒轴20的中空通道21相连通。
具体地，所述的内筒轴8连接驱动电机23，驱动电机23包括定子和转子，转子与内筒轴20固定连接；所述转子的中心处设置通孔，所述的进水管路穿过转子的通孔与内筒轴20的中空通道21相连通。
进一步地，所述的进水管路与转子的通孔之间设置第一动密封结构22，转子的通孔与内筒轴20的中空通道21之间设置第二密封结构。
本实施例同时解决无孔内筒滚筒洗衣机如何精准确定进水量的问题，具体方案如下：
一种滚筒洗衣机，包括内筒8以及与内筒8相连通的进水管路25，所述的内筒8为无孔内筒，洗涤衣物时盛放洗涤水，所述的进水管路25上设置用于检测进水流量的流量传感器1。
本实施例通过在进水管路25上设置流量传感器来监测进水时的流量，当达到设定进水量，关闭进水阀2，完成进水。本实施例采用流量传感器解决了无孔内筒滚筒洗衣机根据设定水位的进水问题，确保了洗涤效果，结构简单，操控方便。
进一步地，本实施例的滚筒洗衣机，包括进水阀2、洗涤剂盒4，所述的进水管路包括第一进水管和第二进水管，进水阀2的出口端通过第一进水管连通洗涤剂盒4，洗涤剂盒4的出口端通过第二进水管连通内筒8，所述的流量传感器设置在第一进水管或 者第二进水管上。
作为本实施例的一种实施方式，所述的流量传感器为转子流量传感器，或者涡轮流量传感器，或者超声波流量传感器，或者电磁流量传感器，或者孔板流量传感器。
本实施例还解决无孔内筒滚筒洗衣机如何保证密封舱气压不平衡的问题，具体是，突然的电磁阀断水，尤其的是自来水管网断水，形成负压，将密封舱内的洗涤水回洗至管网；或者内部有气体，进水困难的问题。
本实施例的一种滚筒洗衣机，包括内筒8，内筒8为无孔内筒，洗涤衣物时盛放洗涤水，还包括用于连通内筒8与外界环境以平衡内筒内部气压的气压平衡机构。
进水时，内筒的密封舱内的气体受压可以通过该均平衡机构溢出，保证气压平衡。
突然断水时，外部大气可以迅速进入内筒的密封舱，并破坏倒吸，保证气压平衡，避免洗涤水被吸入自来水管网。
其他比如脱水时，该气压平衡机构也可以保证内筒气压平衡。
作为本实施例的一种实施方式，所述的气压平衡机构包括设置在内筒8上的均压孔道，所述均压孔道连通内筒8内部的一端设置在内筒8上靠近旋转中心轴位置处且始终高于内筒8内的最高水位位置。
具体地，所述的均压孔道开设在内筒轴20上连通内筒8内部与外界环境，所述内筒8内的最高水位低于内筒轴20。这样可以防止内筒内的水由均压孔道流出。
本实施例所述均压孔道包括第一孔道段和第二孔道段，第一孔道段与中空通道相平行设置，其一端连通内筒内部，第二孔道段的一端与第一孔道段相连通，另一端延伸至内筒轴的外周壁上与外筒的内部相通。优选地，所述的第二孔道段与第一孔道段相垂直设置形成L型的均压孔道。
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。
