Description

用于洗涤设备的进水装置及洗涤设备 技术领域
本发明属于洗涤设备技术领域，具体提供一种用于洗涤设备的进水装置及洗涤设备。
背景技术
洗涤设备包括洗衣机、洗鞋机以及洗碗机等，一般都是通过水洗方式，即在洗涤时都需要进水。
随着科技的不断进步与发展，洗涤设备的功能性朝着越来越多样性的方向发展，这些功能性有些也需要通过进水实现。例如，具有干衣功能的洗衣机，在进行烘干的时候，需要进水到冷凝器进行烘干风的冷凝。由于不同的功能对于进水流量的要求不同，为了实现与进水相关的功能性，现有技术一般通过增加进水管路来实现。然而，每增加一种功能都增加一个管路，这就造成整体结构的体积变大和成本的增加。
以洗衣机为例，为了满足用户使用需求的不断增加，现有的洗衣机一般都增加了烘干功能，然而，因为在向冷凝器进水时需要两种不同流量的供水，其中一种小流量的持续进水，提供冷凝供水，一种大流量供水提供冲洗烘干冷凝器线屑等作用，为此，洗衣机上又新增了两个独立的进水管路且每个进水管路上设置有独立的电磁阀以实现不同流量的进水，使得水路结构的体积更大，制造成本更高。
因此，本领域需要一种用于洗涤设备的进水装置及洗涤设备来解决上述问题。

具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。例如，虽然下述的实施方式是结合洗衣机来解释说明的，但是，这并不是限制性的，此外，本发明的技术方案同样适用于其他洗涤设备，例如洗鞋机、洗碗机或洗干一体机等，这种应用对象的改变并不偏离本发明的原理和范围。
需要说明的是，在本发明的描述中，术语“上”、“下”、“左”、“右”、“前”、“后”、“顶”、“底”、“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
此外，还需要说明的是，在本发明的描述中，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。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
基于背景技术指出的现有洗衣机的进水结构体积大、成本高的问题，本发明提供了一种用于洗衣机的进水装置及洗衣机，旨在减小进水装置的体积，降低进水装置的制造成本。
具体地，本发明的洗衣机包括箱体以及设置在箱体内的冷凝器、洗涤剂投放盒和进水装置。其中，进水装置包括本体以及设置在本体上的第一进水组件、第二进水组件、连通组件、第一限流构件和第二限流构件，第一限流构件和第二限流构件沿水的流动方向依次设置在第一进水组件上，并且，第一限流构件的流量小于第二限流构件的流量，第一进水组件与冷凝器连通，第二进水组件与洗涤剂投放盒连通，连通组件包括用于连通第一进水组件和第二进水组件的连通管路以及用于控制连通管路通断的导通控制阀，并且，第一进水组件与连通管路的连接处位于第一限流构件和第二限流构件之间。
当第一进水组件与外部供水源接通，第二进水组件与外部供水源断开且导通控制阀关闭时，水进入第一进水组件，在第一限流构件的限流作用下，第一进水组件以小流量向冷凝器供水。需要说明的是，因为第一限流构件的流量小于第二限流构件的流量，此时的第二限流构件不起限流作用。
当第一进水组件与外部供水源断开，第二进水组件与外部供水源接通且导通控制阀接通时，水进入第二进水组件，然后分成两股水流，其中一股水流经连通管路进入第一进水组件，因为第一进水组件与连通管路的连接处位于第一限流构件和第二限流构件之间，所以水流不再流经第一限流构件，而是直接流向第二限流构件，在第二限流构件的限流作用下，第一进水组件以大流量向冷凝器供水。
通过这样的设置，使得第一进水组件能够实现两种流量的进水，与现有技术相比，进水装置的体积更小，制造成本更低。
此外，通过设置在第一进水组件上的第一限流构件和第二限流构件，能够实现更精确的流量控制，并且，在实际应用中，可以根据不同的功能，更换不同型号的限流构件，方便灵活，适用范围更广。
下面结合三个具体的实施方式来详细地介绍本发明的技术方案。
实施例一
如图1、图2和图6所示，本发明的进水装置包括本体7以及设置在本体7上的第一进水组件1、第二进水组件2、连通组件3、第一限流构件4、第二限流构件5和第三限流构件6。本体7上形成有集中供水口71，集中供水口71与外部供水源连接，第一进水组件1和第二进水组件2均与集中供水口71连通。
需要说明的是，第一进水组件1和第二进水组件2也可以使用两个独立的供水口，或者，直接与外部供水源连接，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
如图1、图2和图6所示，第一进水组件1包括第一控制阀11和第一进水管路12。其中，第一控制阀11优选为电磁阀，记为第一电磁阀11，第一电磁阀11的进口(图中未示出)与集中供水口71连通，第一电磁阀11的出口111与第一进水管路12的进水口121连通，第一电磁阀11能够控制第一进水管路12与集中供水口71之间的通断，第一限流构件4设置在第一电磁阀11的出口111内(详见图6)，第二限流构件5设置在第一进水管路12内(详见图2)，即第一限流构件4和第二限流构件5沿水的流动方向依次设置，第一限流构件4的流量小于第二限流构件5的流量。
如图1、图2、图6和图7所示，第二进水组件2包括第二控制阀21和第二进水管路22，第二控制阀21的进口(图中未示出)与集中供水口71连通，第二控制阀21包括两个出口，记为第一出口211和第二出口212，第一出口211与连通组件3连通(详见图6)，第二出口212与第二进水管路22连通(详见图7)。在一种优选地情形中，第二控制阀21和第二进水管路22的数量均为两个，并且，第二控制阀21与第二进水管路22一一对应。其中，第二控制阀21也优选为电磁阀， 记为第二电磁阀21，第二电磁阀21能够控制第二进水管路22以及连通组件3与集中供水口71之间的通断。
如图1、图2、图6和图7所示，连通组件3包括用于连通第一进水组件1和第二进水组件2的连通管路31以及用于控制连通管路31通断的导通控制阀32，第一进水组件1与连通管路31的连接处位于第一限流构件4和第二限流构件5之间。其中，连通管路31的一端与第一进水管路12的进水口121(进水口121位于第一限流构件4和第二限流构件5之间)连通，连通管路31的另一端与两个第二控制阀21的第二出口212均连通；导通控制阀32优选为单向逆止阀32，单向逆止阀32的数量也为两个，分别设置在两个第二电磁阀21的第一出口211内(详见图6)，以防止水从第一出口211进入第二电磁阀21；第三限流构件6的数量也为两个，分别设置在两个第二进水管路22内(详见图2)。
如图1、图2、图7和图8所示，连通管路31包括环形板311和盖板312，环形板311的底部与进水装置的本体7密封连接，环形板311的顶部与盖板312密封连接，从而形成一个密封的连通管路31。在一种优选的情形中，环形板311与本体7一体成型制造，环形板311与盖板312固定连接，方便对第一限流构件4和单向逆止阀32进行检查和更换。
需要说明的是，连通管路31的具体结构并不限于上述的具体结构形式，例如，连通管路31可以设置为一个圆形管，圆形管的一端与第一进水管路12连接，圆形管的侧壁上开设两个口，分别与两个第二电磁阀21的第一出口211连通，等等，这种对连通管路31的具体结构形式的调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围直接。
下面介绍一下本发明的进水装置的工作原理。
当第一电磁阀11接通，第二电磁阀21断开时，水经第一电磁阀11进入第一进水管路12内，且在第一限流构件4的限流作用下，进入第一进水管路12的流量较小，使得第一进水管路12能够提供小流量供水。此外，在单向逆止阀32的作用下，水流不会进入第二电磁阀21，更不会进入第二进水管路22，即，在这种情形下，只有第一进水管路12以小流量供水。
当第一电磁阀11断开，两个第二电磁阀21中一个接通另一个断开时，水进入该接通的第二电磁阀21后，分成两股水流，其中一股水流经该第二电磁阀21的第一出口211进入连通管路31，由于连通管路31与第一进水管路12的进水口121(进水口121位于第一限流构件4和第二限流构件5之间)连接，所以该股水流不会经过第一限流构件4，而是沿着连通管路31直接进入第一进水管路12内，在第二限流构件5的限流作用下，使得第二进水管路22能够提供大流量供水；另一股水流经该第二电磁阀21的第二出口212进入第二进水管路22内。此外，在单向逆止阀32的作用下，进入连通管路31内的水流不会进入处于断开状态的第二电磁阀21，更不会进入到与该处于断开状态的第二电磁阀21连通的第二进水管路22。即，在这种情形下，第一进水管路12以大流量供水，两个第二进水管路22中的一个供水，并且，第二进水组件2的两个第二进水管路22可以独立供水，相互之间不受影响。
当第一电磁阀11断开，两个第二电磁阀21均接通时，水进入两个第二电磁阀21后，各自分成两股水流，以其中一路(第二电磁阀21+第二进水管路22)为例，两股水流中的一股水流经第二电磁阀21的第一出口211进入连通管路31，然后沿着连通管路31进入第一进水管路12内，在第二限流构件5的限流作用下，使得第二进水管路22能够提供大流量供水，并且，在第二限流构件5的限流作用下，无论是接通一个第二电磁阀21还是接通两个第二电磁阀21，第二进水管路22的供水量保持不变，从而实现流量的精确控制；另一股水流经第二电磁阀21的第二出口212进入第二进水管路22内，并且，由于两路(第二电磁阀21+第二进水管路22)的结构完全相同，此时的两个第二进水管路22的流量相同。即，在这种情形下，第一进水管路12以大流量供水，两个第二进水管路22同时供水且供水量相同。
通过这样的设置，本发明的进水装置至少具备以下优点：
第一，使得第一进水管路12能够实现两种不同流量的供水，从而减少了一个电磁阀(电磁阀的价格比较昂贵)和一个进水管路，进而能够减小进水装置的体积和制造成本；
第二，通过设置限流构件(第一限流构件4、第二限流构件5和第三限流构件6)，能够实现流量的准确控制，并且，在实际应用中， 可以根据不同的功能，更换不同型号的限流构件，方便灵活，适用范围更广；
第三，两个第二进水管路22既能够独立供水(互补影响)，又能够同时供水且供水量相同，当两个第二进水管路22同时供水时，能够实现对冲，改变水的流动方向，从而能够再减少一个电磁阀和一个进水管路；具体而言，在一种可能的情形中，如图14所示，洗涤剂投放盒8包括壳体，壳体的内部设置有三个功能区，分别为第一功能区81、第二功能区82和第三功能区83，可以用于存放不同的洗涤剂，还包括与第一功能区81、第二功能区82和第三功能区83连通的两个进水管84，两个进水管84的出口段841的出口相对且倾斜设置，两个进水管84分别与两个第二进水管路22连接，当仅左侧的进水管84进水时，水流入第三功能区83，当仅右侧的进水管84进水时，水流入第一功能区81，当两个进水管84同时进水时，两股水流对冲，水的流动方向改变从而流入第二功能区82。即，通过两个第二进水管路22即可实现对三个功能区的供水，从而减少了一个电磁阀和进水管路，进一步减小了进水装置的体积和制造成本。
下面结合图9和图10来详细地介绍一种单向逆止阀32的结构。
如图9和图10所示，单向逆止阀32包括阀座321、复位弹簧322和密封圈323，阀座321上设置有导向柱324，复位弹簧322套设在导向柱324上，密封圈323套设在阀座321上。
在安装好的情形下(单向逆止阀32安装到第二电磁阀21的第一出口211内)，如图3、图4和图5所示，复位弹簧322的底端抵靠在阀座321上，复位弹簧322的顶端抵靠在连通管路31的盖板312上，盖板312上设置有导向孔3121(详见图8)，导向柱324的顶部插入导向孔3121内，水进入第二电磁阀21后，顶着阀座321向上移动，以将第一出口211打开，水从第一出口211进入连通管路31，进水结束后，在复位弹簧322的作用下，阀座321向下移动，重新将第一出口211密封，在密封状态下，密封圈323位于第一出口211的内壁与阀座321之间。
需要说明的是，上述单向逆止阀32的结构并不构成对本发明的限制，采用其他结构的单向逆止阀32也在本发明的保护范围之内。
下面结合图11至13来详细地介绍一种限流构件的结构。
首选，需要说明的是，在本实施例中，第一限流构件4、第二限流构件5和第三限流构件6采用的同种类型的限流构件，以第二限流构件5为例，如图11至13所示，包括限流座51和限流板52，限流座51上设置有限流孔511、连接轴512、凸起513以及密封环514，限流板52套设在连接轴512上，限流板52的右侧抵靠在凸起513上以使限流板52与限流座51之间具有间隙，通过该间隙起到限流的作用，间隙的大小决定了流量的大小，该间隙与限流孔511是相通的，水从限流孔511流出，在安装好的情形下，密封环514抵靠在第一进水管路12的内壁上。
需要说明的是，第一限流构件4、第二限流构件5和第三限流构件6可以均采用上述类型的限流构件，也可以分别采用其他不同类型的限流构件，这种灵活地调整和改变并不偏离本发明的原理和范围，均应限定在本发明的保护范围之内。
此外，还需要说明的是，虽然本发明针对限流构件只提供了一种实施例，但是，本领域技术人员应该理解的是，本发明对现有技术的贡献主要体现在将第一限流构件4(小流量)和第二限流构件5(大流量)沿水的流动方向依次设置在第一进水组件1上，并且，第一进水组件1与连通组件3的连接处位于第一限流构件4和第二限流构件5之间，从而使得第一进水组件1能够实现两种流量的供水，并且能够实现更准确的流量控制，因此，使用其他结构的限流构件也在本发明的保护范围之内。
实施例二
在实施例一的其它设置条件不变的基础上，取消第三限流构件6。在第二进水组件2对应的功能对进水流量的要求不高时，可以去掉第三限流构件6。
实施例三
在实施一的其它设置条件不变的基础上，取消一个第二电磁阀21、单向逆止阀32、第二进水管路22和第三限流构件6。即，第二进水组件2只包括一个第二电磁阀21和第二进水管路22，单向逆止阀32 和第三限流构件6均为一个，单向逆止阀32设置在第二电磁阀21的第一出口211内，第三限流构件6设置在第二进水管路22内。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
