相关申请的交叉引用
本申请要求无锡小天鹅股份有限公司公司于2018年3月9日提交的、发明名称为“洗衣机”的、中国专利申请号“2018203316531”的优先权。
技术领域
本申请涉及电器制造技术领域，具体而言，涉及一种洗衣机。
背景技术
随着洗衣机技术的不断发展，洗衣机已经越来越趋向于大容量，而在洗衣机逐渐趋于大容量的同时，必然会导致洗衣机整体尺寸的增大，所以提供一种小体积大容量的洗衣机很有必要；于此同时，现有的洗衣机在洗涤时水分布在旋转桶和盛水桶内，即盛水桶和旋转桶也之间分布有水，用水量较大，造成水资源的浪费；现有的洗衣机污垢易留存在盛水桶和旋转桶之间，从而滋生细菌并且因为盛水桶和旋转桶之间分布有水，对于洗涤剂的用量也较多，造成洗涤剂的资源浪费，不利于节约成本。
为此，相关技术提出了省去盛水桶而仅保留旋转桶的洗衣机，如图1所示，旋转桶210’底部连接有桶排水通道250’，且桶排水通道250’内设有桶排水控制阀260’，接水盘400’底部连接有盘排水通道270’。洗衣机1’洗涤排水时，桶排水控制阀260’打开，旋转桶210’内的水由桶排水通道250’排出；洗衣机1’脱水时，旋转桶210’内的水在离心力的作用下通过导水腔240’进入接水盘400’，再通过盘排水通道270’排出。但由于接水盘400’的高度较低，在排水不畅时，例如桶排水控制阀260’堵塞、排水管700’太长或弯曲抬高，在旋转桶210’和接水盘400’的压力差作用下，旋转桶210’排出的水会经过盘排水通道270’进入接水盘并持续上升，最终从接水盘400’的上沿溢出，造成溢水风险。
实用新型内容
本申请旨在至少在一定程度上解决相关技术中的上述技术问题之一。为此，本申请提出一种洗衣机，该洗衣机采用单桶结构，不仅容量大、节水和免污、成本低，而且能够避免溢水风险。
根据本申请的实施例提出一种洗衣机，所述洗衣机包括：旋转桶；接水盘，所述接水盘的至少一部分位于所述旋转桶的下方；桶排水通道，所述桶排水通道与所述旋转桶连通，所述桶排水通道设有用于打开和关闭所述桶排水通道的桶排水控制阀；盘排水通道，所述盘排水通道与所述接水盘连通，所述盘排水通道设有用于打开和关闭所述盘排水通道的盘排水控制阀；排水管，所述排水管分别与所述桶排水通道和所述盘排水通道连通。
根据本申请实施例的洗衣机，采用单桶结构，即仅设置旋转桶而不设置盛水桶，简化了结构、提升了容量、减少了污垢和细菌滋生，且更加节水，同时能够提高脱水效果。并且，通过在盘排水通道内设置盘排水控制阀，能够避免旋转桶排出的水由盘排水通道进入接水盘，从而防止接水盘溢水。
根据本申请的一些具体实施例，所述盘排水控制阀为仅允许所述盘排水通道内的水单向流向所述排水管的单向阀。
进一步地，所述单向阀包括：阀门，所述阀门在打开所述盘排水通道的打开位置和关闭所述盘排水通道的关闭位置之间可转动地安装于所述盘排水通道内；止挡件，所述止挡件设于所述盘排水通道内，所述阀门处于所述关闭位置时，所述止挡件止挡在所述阀门的远离所述排水管的一侧。

在本申请的描述中，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，可以是两个元件内部的连通。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申请中的具体含义。
下面参考附图描述根据本申请实施例的洗衣机1。
如图2-图4所示，根据本申请实施例的洗衣机1包括旋转桶210、接水盘400、桶排水通道250、桶排水控制阀260、盘排水通道270、盘排水控制阀280和排水管700。
接水盘400的至少一部分位于旋转桶210的下方。桶排水通道250与旋转桶210连通，旋转桶210内的水可通过桶排水通道250直接排出，桶排水通道250设有用于打开和关闭桶排水通道250的桶排水控制阀260。盘排水通道270与接水盘400连通，接水盘400内的水可通过盘排水通道270直接排出，盘排水通道270设有用于打开和关闭盘排水通道270的盘排水控制阀280。排水管700分别与桶排水通道250和盘排水通道270连通。本领域的技术人员可以理解地是，桶排水通道250和盘排水通道270可以先连通汇总后再与排水管700相连，也可以使排水管700分岔以分别与桶排水通道250和盘排水通道270相连，附图中示出了桶排水通道250和盘排水通道270可以先连通汇总后再与排水管700相连的示例。
根据本申请实施例的洗衣机1，采用单桶结构，即仅设置旋转桶210而不设置盛水桶，这样洗涤时水在旋转桶210内，更加节水，且通过进一步设置接水盘400，可以使旋转桶210内的水先被引导至接水盘400，再从接水盘400排出。由此，在取消盛水桶以简化结构、提升容量、减少污垢和细菌滋生、节水的情况下，同时能够提高脱水效果。
并且，通过在盘排水通道270内设置盘排水控制阀280，可以利用盘排水控制阀280打开和关闭盘排水通道270。例如，可以在洗衣机1洗涤排水时，桶排水控制阀260打开桶 排水通道250，旋转桶210内的水经桶排水通道250排出，且通过盘排水控制阀280关闭盘排水通道270，这样即使旋转桶210内的水位较高或排水不畅，旋转桶210排出的水也不会经盘排水通道270进入接水盘400而溢出；而在洗衣机1脱水或旋转桶210内的水位异常过高时，通过盘排水控制阀280打开盘排水通道270，这样旋转桶210内的水在离心力的作用下先进入接水盘400，再经盘排水通道270和排水管700排出。
因此，根据本申请实施例的洗衣机采用单桶结构，不仅容量大、节水和免污、成本低，而且能够避免溢水风险。
下面参考附图描述根据本申请具体实施例的洗衣机1。
如图2-图4所示，根据本申请实施例的洗衣机1包括旋转桶210、导水罩220、接水盘400、桶排水通道250、桶排水控制阀260、盘排水通道270、盘排水控制阀280、排水管700、波轮300和驱动单元500。
其中，为了便于旋转桶210和接水盘400排水以及提高排净效果，桶排水通道250的上端与旋转桶210的底壁连通且邻近旋转桶210的底壁的中心处，盘排水通道270的上端与接水盘400的底壁连通。
在本申请的一些具体实施例中，如图2和图4所示，旋转桶210的周壁和/或底壁上设有出水口211，导水罩220设于旋转桶210的内周壁面，且导水罩220罩设出水口211，导水罩220设有进水口221，且导水罩220限定出与进水口221和出水口211连通的导水腔240。旋转桶210内因离心力作用而上升的液体通过进水口221进入至导水腔240内并通过出水口211被引导至接水盘400。
具体而言，洗衣机1在脱水时，旋转桶210旋转，即导水罩220随旋转桶210旋转，旋转桶210内的液体在离心力的作用下向上移动，并由进水口221进入导水腔240，进入导水腔240的液体被导水罩220引导至出水口211，并由出水口211排出至接水盘400。
由此，通过在旋转桶210的内周壁面上设置导水罩220，且在导水罩220上设置进水口221、在旋转桶210的周壁和/底壁设置出水口211，脱水时旋转桶210内的水在离心力的作用下上升，并由进水口221进入导水罩220内，在导水罩220的引导下流至出水口211，从而通过出水口211排出至接水盘400。由此，在取消盛水桶以简化结构、提升容量、减少污垢和细菌滋生、节水的情况下，同时能够提高脱水效果。
并且，出水口211可以设置在旋转桶210的周壁上，也可以设置在旋转桶210的底壁上，或者出水口211设置在周壁和底壁上。具体的，出水口211设置在旋转桶210的周壁上，这样导水罩220罩设出水口211，且导水罩220的下端仅与旋转桶210的周壁连接，利于导水罩220与旋转桶210的周壁的密封。当然，本申请中的出水口211也可以设置在旋转桶210的底壁上，导水罩220罩设出水口211，利于提高脱水时的脱水效率，脱水效 果好，并且可以有效的减少水从出水口211中的飞溅。出水口211设置在周壁和底壁上，既利于导水罩220与旋转桶210的周壁的密封，也利于提高脱水时的脱水效率，并且可以有效的防止水从出水口211中飞溅出来。
在本申请的一些具体实施例中，如图2和图4所示，波轮300可旋转地设在旋转桶210内。接水盘400用于支撑旋转桶210，这里可以是直接支撑，也可以是间接支撑。在本实施例中，驱动单元500安装在接水盘400上，例如安装在接水盘400的下表面，用于驱动旋转桶210和波轮300中的至少一个旋转。驱动单元500设有穿设接水盘400且与接水盘400连接配合的驱动轴组件501，接水盘400与旋转桶210之间设有与驱动轴组件501连接的支撑板502，支撑板502与旋转桶210固定连接。导水腔240将由旋转桶210甩出的液体通过出水口211引导至接水盘400。
由此，通过设置接水盘400，不仅可以盛接导水腔240内排出的液体，而且可以将驱动单元500安装在接水盘400上，实现承载驱动单元500的作用。
在本申请的一些具体实施例中，如图2和图4所示，进水口221设在导水罩220的上部，出水口211设置在旋转桶210的周壁的下部。这里可以理解地是，导水罩220的上部是指，导水罩220的在上下方向上的中心以上的部分，旋转桶210的下部是指，旋转桶210的在上下方向上的中心以下的部分。由此，脱水时，旋转桶210旋转，旋转桶210内的水在离心力的作用下上升，位于导水罩220上部的进水口221能够更好地收集上升的水，这部分水由进水口221进入导水罩220内，并在导水罩220的引导下流至旋转桶210下部的出水口211，从而进一步提高脱水效率和脱净效果。
进一步地，如图2和图4所示，进水口221设在导水罩220的上端，以进一步便于收集旋转桶210内在离心力作用下上升到旋转桶210上端的液体。出水口211设在旋转桶210的周壁且邻近旋转桶210的底壁设置，出水口211与旋转桶210的底壁间隔预定距离，由此，便于导水罩220与旋转桶210周壁的密封，且可以降低接水盘400的侧壁的高度，进而节约用料、降低成本。
进一步地，如图2和图4所示，为了提高洗衣机1的排水效果，出水口211为多个，多个出水口211沿旋转桶210的周向等间隔设置，导水罩220为多个，多个导水罩220沿旋转桶210的周向间隔设置，每个导水罩220罩设至少一个相对应的出水口211。
在本申请的一些具体实施例中，如图2和图3所示，盘排水控制阀280为仅允许盘排水通道270内的水单向流向排水管700的单向阀。换言之，盘排水控制阀280仅允许盘排水通道270内的水流向排水管700，而不允许盘排水通道270内的水流向接水盘400，从而实现自动防溢。
具体而言，如图2和图3所示，盘排水通道270具有沿水平方向延伸的水平段，单向 阀(即盘排水控制阀280)设于水平段且包括阀门281和止挡件282。
阀门281在打开盘排水通道270的打开位置和关闭盘排水通道270的关闭位置之间可转动地安装于盘排水通道270内。止挡件282设于盘排水通道270内，阀门281处于所述关闭位置时，止挡件282止挡在阀门281的远离排水管700的一侧。
更具体地，旋转桶210内的水位较高或排水不畅时，在水压作用下，阀门281处于关闭位置且止挡在止挡件282上，旋转桶210排出的水不会经盘排水通道270进入接水盘400溢出而造成风险。旋转桶210内的水位异常过高或脱水时，旋转桶210内的水会经依次经过进水口221、导水腔240和出水口211进入接水盘400，由于阀门281向打开位置转动时不受止挡件282止挡，阀门281在水流作用下转动至打开位置，从而使接水盘400内的水经盘排水通道270和排水管700排出。
可选地，止挡件282与盘排水通道270的内壁一体成型，由此可以提高两者的结合强度，从而提高止挡件282对阀门281的止挡效果，以提高单向阀的单向导通的可靠性。
在本申请的一些具体实施例中，如图4所示，盘排水控制阀280为电动阀，洗衣机1还包括与所述电动阀通讯且用于控制所述电动阀的控制器(图中未示出)。由此通过电动控制盘排水控制阀280以实现自动防溢。
举例而言，洗衣机1处于排水模式时，桶排水控制阀260打开桶排水通道250，所述控制器控制所述电动阀关闭盘排水通道270；洗衣机1处于脱水模式时，所述控制器控制所述电动阀打开盘排水通道270。
进一步地，洗衣机1还包括水位检测装置(图中未示出)，所述水位检测装置用于检测旋转桶210内的水位，所述水位检测装置与所述控制器通讯，当所述水位检测装置检测到旋转桶210内的水位达到预定异常超高值时，所述控制器控制所述电动阀打开盘排水通道270。
具体地，洗衣机1排水时，桶排水控制阀260打开桶排水通道250，旋转桶210内的水经桶排水通道250排出，且控制器控制电动阀处于关闭状态，即使旋转桶210内的水位较高或排水不畅，旋转桶210排出的水也不会经盘排水通道270进入接水盘400溢出而造成风险。洗衣机1脱水或旋转桶210内的水位异常过高时，控制器控制电动阀处于打开状态，旋转桶210内的水会经依次经过进水口221、导水腔240和出水口211进入接水盘400，接水盘400内的水经盘排水通道270和排水管700排出。
根据本申请实施例的洗衣机1的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结 构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
