Description

一种内外桶间无水的洗衣机及其控制方法 技术领域
本发明涉及洗衣装置技术领域，具体地，涉及一种内外桶间无水的洗衣机及其控制方法。
背景技术
如图1所示，现有的洗衣机包括壳体16以及设置在壳体16内的外桶15、內桶14A，內桶14A可转动的设置在外桶15内。为了实现衣物的脱水功能，內桶14A的桶壁上布满了脱水孔，这样在进行衣物洗涤时，洗涤水会由脱水孔流至內桶14A与外桶15之间，这部分洗涤水不能得到充分的利用而导致水资源的浪费。
另外，由于內桶14A与外桶15之间存水的问题，会导致在內桶14A的外壁、外桶15的内壁以及內桶14A与外桶15之间的区域滋生污垢，污染用户衣物，严重影响用户的洗衣体验。
为了解决上述问题，如图2所示，现有一种洗衣机，其主要的结构特点是內桶14B的桶壁上无孔，这样，在洗涤时，只在内桶14B中有水，內桶14B与外桶15之间无水，不仅节省了洗衣的用水量，而且杜绝了內桶14B与外桶15之间滋生污垢，避免衣物污染，提高洗涤效果，提升用户体验。
上述在洗涤时內桶与外桶间无水的洗衣机在使用一段时间以后，由于內桶14B上无孔，洗涤后的泥沙等杂物可能无法及时排出，这就导致内桶14B的底部会产生泥沙等杂物积聚，影响用户洗衣效果。
为了解决洗涤时內桶与外桶间无水的洗衣机的泥沙等杂物的排出问题，特提出本发明。

本发明的第一发明目的是提供一种内外桶间无水的洗衣机的控制方法，具体地，采用如下的技术方案：
一种如上述所述内外桶间无水的洗衣机的控制方法，洗衣机执行洗涤/漂洗程序，波轮以转速ω1转动搅拌水流进行衣物洗涤，水流在转速ω1时不能由排沙通道的排沙口流出；
洗衣机执行脱水程序，波轮和内桶同步以转速ω2转动进行衣物脱水，水流在转速ω2时冲刷泥沙等杂物由排沙通道的排沙口排出；
其中，转速ω1小于转速ω2。
本发明的第三发明目的是提供一种内外桶间无水的洗衣机的控制方法，具体地，采用如下的技术方案：
一种如上述所述内外桶间无水的洗衣机的控制方法，所述的洗衣机还包括排沙程序，排沙程序包括：
洗衣机接收启动排沙程序的指令；
洗衣机控制内桶以转速ω3转动，内桶内的泥沙等杂物在离心作用下经由排沙通道由排沙口排出；
其中，转速ω3大于转速ω1且小于转速ω2，转速ω1为洗衣机洗涤/漂洗时的转速，转速ω2为洗衣机脱水时的转速。
本发明的内外桶间无水的洗衣机，通过在內桶上设置排沙通道在脱水过程中可将衣物上的泥沙等杂物排出。
另外，为了保证洗衣机在洗涤时內桶与外桶之间无水，这就要求泥沙等杂物只在脱水时由排沙通道排出。而由针对洗衣机洗涤和脱水时的工作特点，脱水的转速大于洗涤的转速，脱水时的离心力大于洗涤/漂洗时的离心力。因此，在设置排沙通道时，排沙通道的进沙口、排沙口的设置位置应该满足：洗涤过程中的离心力不能使泥沙等杂物由排沙通道排出，脱水过程中的离心力使泥沙等杂物由排沙通道排出。
本发明利用洗衣机的工作特点设置排沙通道的进沙口、排沙口实现只在脱水时进行泥沙等杂物排放的方式，结构简单，成本较低，能有效解决泥沙残留在內桶内的问题。

具体实施方式
下面结合附图对本发明的一种内外桶间无水的洗衣机及其控制方法进行详细描述：
实施例一
本实施例的一种内外桶间无水的洗衣机，包括：外桶；
内桶，可转动的设置在外桶内；
以及波轮，可转动的设置在内桶的底部；
在洗涤/漂洗过程中，所述的内桶内盛水，内桶与外桶之间无水；
所述内桶的桶壁上设置用于泥沙等杂物排出的排沙通道：洗衣机在脱水过程中，水流冲刷泥沙等杂物由排沙通道排出。
本发明的内外桶间无水的洗衣机，通过在內桶上设置排沙通道在脱水过程中可将衣物上的泥沙等杂物排出。
进一步地，本发明的排沙通道的设置满足：洗衣机在洗涤/漂洗过程中，水流不能由排沙通道流出，在脱水过程中，水流冲刷泥沙等杂物由排沙通道排出。这样可以保证，在洗衣/漂洗过程中，內桶与外桶之间无水，泥沙等杂物只在脱水时由排沙通道排出。
为了保证洗衣机在洗涤时內桶与外桶之间无水，这就要求泥沙等杂物只在脱水时由排沙通道排出。为了实现这一技术目的，可采用以下基本构思：
一方面，可通过控制排沙通道的通断来控制排沙时机。排沙通道的通断可由电气元件的控制实现，也可根据物理结构来控制实现。
作为一种实现方式，可在排沙通道内设置控制其通断的电气阀门，通过控制阀门在洗涤/漂洗时关闭，在脱水时开启，进一步控制在脱水时进行排沙。
作为另一种实现方式，可在排沙通道内设置物理开关来控制其通断，物理开关利用脱水时的转速大于洗涤时的转速，因此，脱水时的离心力更大，在该离心力下，物理开关开启，排沙通道导通，进行排沙。
另一方面，可根据洗衣机洗衣过程中的特点设置排沙通道，主要是通过设置排沙通道的进沙口、排沙口的位置，以保证洗涤水在洗涤/漂洗时无法由排沙通道排出，在脱水时由于离心力更大洗涤水可由排沙通道排出。
针对洗衣机洗涤和脱水时的工作特点，脱水的转速大于洗涤的转速，因此在设置排沙通道时，只需要将排沙通道的进沙口、排沙口按照这一原则进行设置，就能实现这一发明目的。
具体地，本实施例的排沙通道的设置方式为：所述排沙通道的进沙口设置于内桶的底部且位于波轮的下方，排沙通道的排沙口靠近内桶上部的投放口设置且通向内桶与外桶之间；
所述排沙通道的进沙口、排沙口的设置满足：洗衣机在洗涤/漂洗过程中，水流不能由排沙口流出，在脱水过程中，水流冲刷泥沙等杂物由排沙口排出。
本实施例将排沙通道的进沙口设置于内桶的底部且位于波轮的下方，一方面有利于內桶内的泥沙沉积进入排沙通道，另一方面可将排沙通道的进沙口隐藏于波轮的下方，保持內桶观感上的无孔。
本实施例将排沙通道的排沙口靠近内桶上部的投放口设置且通向内桶与外桶之间，以保证在洗涤/漂洗时，洗涤水即使进入到排沙通道，由于排沙通道的排沙口设置的高度可限制其排出。
本实施例的排沙通道可由內桶本身构造形成，內桶的桶壁一体成型出上下贯通的排沙通道。
本实施例的排沙通道也可由盖体结构安装在內桶内壁上与其之间形成上下贯通的排沙通道。
实施例二
如图3及图4所示，本实施例的一种内外桶间无水的洗衣机，内桶的桶壁上安装排沙盖3，排沙盖3与内桶桶壁之间形成排沙通道；
所述排沙通道的进沙口设置于内桶的底部且位于波轮5的下方，排沙通道的排沙口2靠近内桶上部的投放口设置且高于洗衣机的最高水位。
本实施例通过在內桶的桶壁上安装排沙盖3，排沙盖3与內桶桶壁之间具有一定的间隙以形成排沙通道。这种方式，內桶的结构、制造方式不用发生改变，容易实现，成本较低，易于推广实现。
排沙通道的进沙口设置于内桶的底部且位于波轮5的下方，一方面有利于內桶内的泥 沙沉积进入排沙通道，另一方面可将排沙通道的进沙口隐藏于波轮5的下方，保持內桶观感上的无孔。
排沙通道的排沙口靠近内桶上部的投放口设置且高于洗衣机的最高水位，以保证在洗涤/漂洗时，洗涤水即使进入到排沙通道，由于排沙通道的排沙口设置的高度高于洗衣机的最高水位以避免洗涤/漂洗过程中漏水。
作为本实施例的一种优选实施方式，所述的排沙盖3包括顶壁和顶壁相对两侧的侧壁，所述的侧壁与内桶内壁紧密接触，顶壁与内桶内壁之间间隔设置形成排沙通道。
本实施例所述内桶包括内桶底6和沿内桶底围成一圈的桶体4，所述的波轮5可转动的安装在内桶底6，所述的桶体4的上端侧壁上开设排沙开口；所述排沙盖3的一端延伸至内桶底6且与内桶底形成排沙通道的进沙口，另一端与排沙开口配合形成排沙通道的排沙口2。
本实施例通过在桶体4的上端侧壁开设排沙开口，排沙盖3与该排沙开口配合以形成相对密封的排沙口，一方面可保证泥沙只能由此排出，另一方面由于排沙盖3的遮盖，可保持內桶观感上的无孔。
优选地，本实施例排沙通道的进沙口设置在内桶底6的最低位置处。
因此，本实施例通过对排沙通道的进沙口、排沙口安装位置的限定，以保证在洗涤/漂洗时，洗涤水不会由排沙通道排出，在脱水时，泥沙等杂物可由排沙通道排出。
进一步地，本实施例所述排沙盖3延伸至内桶底6的一端包括朝向内桶中心延伸的第一横壁9、与第一横壁9相连且朝向内桶底延伸的第一竖壁10以及与第一竖壁10相连且朝向内桶中心延伸的第二横壁11；所述的第一竖壁10与波轮5外缘相匹配，所述第二横壁11与内桶底6间隔设置形成排沙通道的进沙口。
本实施例的排沙盖3设置在內桶底6的一端根据內桶底6以及波轮5的机构特点进行设计，注意与波轮5的配合，不影响波轮5的正常转动。
另外，将第一竖壁10与波轮5外缘之间间隔设置，使得泥沙由此进入波轮5的下部，进而进入排沙通道的进沙口。
本实施例所述的内桶还包括法兰盘7，法兰盘7安装在内桶底6上，所述的法兰盘7、内桶底6和桶体4围成不漏水的内桶，所述桶体4的上部的投放口上安装平衡环1。桶体4与桶底6，法兰盘7共同构成一个不漏水的内桶，内部盛水用于洗涤衣物。
本实施例桶体上靠近平衡环1的一端设置一圈脱水孔8，所述的排沙开口位于脱水孔8之上。本实施例的平衡环1内侧部分伸入到桶体4内部，而脱水孔8设置正对着平衡环1，这样平衡环1可以遮挡这一圈脱水孔8，可保持內桶观感上的无孔。
本实施例的脱水孔8设置位置可保证在洗涤/漂洗时，洗涤水不会由脱水孔排出，而在脱水时，甩出的水会由脱水孔8排出到外桶，进一步被排出。
本实施例将排沙开口设置在脱水孔8上，肯定也能实现在洗涤/漂洗时，洗涤水不会由排沙通道排出，在脱水时，泥沙等杂物可由排沙通道排出。
作为本实施例的一种实施方式，所述的排沙盖3包括多个，分别沿着内桶内壁的圆周方向均匀分布。多个排沙盖3与內桶内壁之间形成多个排沙通道，更有利于泥沙的排出。
优选地，所述排沙盖包括1-6个；进一步优选地，所述的排沙盖包括4个。
为了实现排沙盖3的上下贯通安装，为了配合排沙盖3的安装，內桶底6的内壁上对应排沙盖3处设置安装口12，內桶底6的内壁其余部位设置一周搅拌凸起。
本实施例的内外桶间无水的洗衣机：
(1)桶体4与桶底6，法兰盘7共同构成一个不漏水的内桶，各部件的相互连接部位应可靠密封，不能漏水。
(2)排沙盖3和桶底6形成的底部开口，应当位于内桶底部，以利于泥沙沿开口进入排沙通道。
(3)桶体4上部和排沙盖3上部，应设有排沙开口以利于泥沙排出，开口应高于洗衣机最高洗涤水位对应的高度以免洗涤过程中漏水。
(4)排沙盖3和桶底6、桶体4形成的排沙通道，应当从内桶最底部一直延伸到最上端的投放口处，中间应当顺畅，以利于泥沙排出。
(5)允许多个排沙盖3做成连成一体的结构，以更加利于泥沙排出。
(6)排沙盖3和桶底6、桶体4优选可形成有效密封的配合，以利于泥沙排出。
本实施例的内外桶间无水的洗衣机：
洗涤/漂洗时，桶体4与桶底6，法兰盘7共同构成一个不漏水的内桶，内部盛水用于洗涤衣物。
洗涤/漂洗过程中，如果衣物上沾染有泥沙等异物，洗涤下来的泥沙由于重力的作用，会下沉到波轮5和桶底6、法兰7形成的间隙中。
脱水时，电机17驱动内桶做高速旋转，高速旋转的水流带动波轮5和桶底6、法兰7形成的间隙中的泥沙，沿着排沙盖3和桶底6、桶体4形成的排沙通道上升至排沙口2处，甩出洗衣机内桶，从而解决泥沙积聚的问题。
本实施例利用该方式形成的桶间无水洗衣机，结构简单，成本较低，且能有效解决底部泥沙积聚的问题。
实施例三
本实施例提供了一种如上述所述内外桶间无水的洗衣机的控制方法：
洗衣机执行洗涤/漂洗程序，波轮以转速ω1转动搅拌水流进行衣物洗涤，水流在转速ω1时不能由排沙通道的排沙口流出；
洗衣机执行脱水程序，波轮和内桶同步以转速ω2转动进行衣物脱水，水流在转速ω2时冲刷泥沙等杂物由排沙通道的排沙口排出；
其中，转速ω1小于转速ω2。
本实施例的控制方法通过对洗涤/漂洗时转速ω1和脱水时转速ω2的设置，以实现排沙要求，简单方便，易于实现。
实施例四
本实施例提供了一种如上述所述内外桶间无水的洗衣机的控制方法，所述的洗衣机还包括排沙程序，排沙程序包括：
洗衣机接收启动排沙程序的指令；
洗衣机控制内桶以转速ω3转动，内桶内的泥沙等杂物在离心作用下经由排沙通道由排沙口排出；
其中，转速ω3大于转速ω1且小于转速ω2，转速ω1为洗衣机洗涤/漂洗时的转速，转速ω2为洗衣机脱水时的转速。
本实施例通过设置排沙程序，在排沙程序中洗衣机执行转速ω3，转速ω3的设定满足了泥沙等杂物在洗涤/漂洗的转速下不能由排沙通道排出，而在达到转速ω3或者更大时将泥沙由排沙通道排出，实现排沙效果。
本实施例的控制方法不用改变洗衣机的洗衣程序，设置单独的排沙程序，排沙效果更好。
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。
