技术领域
本申请涉及生活电器技术领域,尤其是涉及一种分水阀组件、洗碗机和家用电器。
背景技术
通常地,洗碗机为了提高对餐具的清洗效果,通常会设置加热装置,通过对洗涤水进行加热,从而高温洗涤水将餐具上的污染物冲走的同时,并将热量带到餐具上,从而洗碗机系统能在较短的洗涤时间内获得较高的洗净率和干燥率。但是由于系统结构的限制,洗涤水在通过加热装置时,水侧通道流动阻力较大,会使得洗碗机喷淋臂喷射压力下降或者洗涤泵耗功增大等问题。而加热过程在洗碗机洗涤总时间内只占一部分的时间。将加热系统直接接入洗涤水循环流路内,在非加热时段内,水流经加热装置所产生的阻力损失会造成喷淋臂水流喷射压力降低和洗涤水流量下降的情况,从而导致餐具洗涤效果变差。

请结合图1和图8及9,本申请实施方式的分水阀组件10能够应用于本申请实施方式的家用电器200中。在一个例子中,家用电器200可为洗碗机或者其他需要使用液体(例如水)的家用清洗设备。
家用电器200包括分水阀组件10、腔体20、喷臂30和加热装置40。其中,腔体20内形成有腔室21。喷臂30至少部分地设置于腔室21内。喷臂30开设有多个喷淋孔(图未示出)。洗涤液能够经由多个喷淋孔喷射至腔室21内,以清洗位于腔室21内的物品(例如餐具)。在图1所示的例子中,喷臂30包括间隔设置的第一喷臂31、第二喷臂32和第三喷臂33。第一喷臂31、第二喷臂32和第三喷臂33可依次为上喷臂、中喷臂和下喷臂。第一喷臂31、第二喷臂32和第三喷臂33分别可用于清洗位于腔室21内不同位置的物品。加热装置40用于对洗涤水进行加热,加热后的洗涤水可经由喷臂30的喷淋孔喷出。
分水阀组件10包括壳体11和分水阀12。壳体11内形成有分水腔111。壳体11开设有进水口112、回水口113、第一出水口114和第二出水口115。其中,第一出水口114能够通过壳体11的外部管路连通回水口113。分水阀12设置于分水腔111内并能够将分水腔111分为隔开的第一分水腔1111和第二分水腔1112。第一分水腔1111连通进水口112。分水阀12能够在分水腔111内转动以使第一分水腔1111连通进水口112及第一出水口114和使第二分水腔1112连通第二出水口115及回水口113,及使进水口112及第一出水口114隔断和使第一分水腔1111连通进水口112及第二出水口115。
需要说明的是,在分水阀12在分水腔111内转动时,分水阀组件10能够实现下述的第一状态和第二状态。第一状态和第二状态为不同时的状态。具体地,在分水阀12转动至使第一分水腔1111连通进水口112及第一出水口114时,第二分水腔1112能够连通第二出水口115及回水口113,即实现分水阀组件10的第一状态,这时经进水口112的水能够经由第一分水腔1111从第一出水口114流出,而由第一出水口114流出的水能够经由回水口113流入第二分水腔1112,并经由第二分水腔1112从第二出水口115流出。在家用电器200需要使用加热装置40加热时,可使分水阀组件10处于上述的第一状态,这时可认为家用电器200处于加热模式。在分水阀12转动至使进水口112和第一出水口114隔断时,第一分水腔1111连通进水口112及第二出水口115,即实现分水阀组件10的第二状态,这时经进水口112的水能够经由第一分水腔1111从第二出水口115直接流出。在家用电器200不需要使用加热装置40加热时,可使分水阀组件10处于上述的第二状态,这时可认为家用电器200处于非加热模式。
在本实施方式中,家用电器200还包括集水槽50和洗涤泵60。喷淋到洗涤物品上的洗涤液可以集中被收集在腔室21底部的集水槽50内。集水槽50的底部设置有洗涤出口201。洗涤液从洗涤出口201流出。洗涤泵60的进口与洗涤出口201相连通,洗涤泵60的出口与进水口112连通,从通过洗涤泵60对洗涤液的循环提供动力。加热装置40通过管路连接第一出水口114和回水口113。
如此,在将分水阀组件10应用于家用电器200时,喷臂30能够通过管路连接第二出水口115,这样在需要对水加热时,可转动分水阀12以使第一分水腔1111连通进水口112及第一出水口114,这时经进水口112进入的水能够经由第一分水腔1111从第一出水口114流出并由加热装置40加热,而加热装置40加热后的水能够由回水口113流入第二分水腔1112,并能够由第二出水口115流动至喷臂30以进行喷洒,在不需要对水加热时,可转动分水阀12以使分水阀12隔断进水口112和第一出水口114,这时经进水口112进入的水能够经由第一分水腔1111直接从第二出水口115流动至喷臂30以进行喷洒,这样水不用流经加热装置40,可降低在非加热时段内水流系统内的阻力,减少洗涤泵60耗功增大和洗涤时间较长的问题,进而提升家用电器200的系统洗涤性能。
当然,可以理解,连接第一出水口114和回水口113的外部管路还可以设置其他设备(例如多个加热装置),这可根据具体情况进行设置。在图1所示的例子中,加热装置40采用热泵系统,其包括压缩机41、冷凝器42、节流装置43和蒸发器44,进一步地,压缩机41、冷凝器42、节流装置43、蒸发器44通过管路依次连接成一个密闭的循环系统,冷媒在密闭的循环系统中循环流动。
可以理解,在分水阀12隔断进水口112和第一出水口114时,分水阀12还可关闭回水口113以使第二出水口115与回水口113隔断。
需要说明的是,分水阀12在分水腔111内转动时,第一分水腔1111和第二分水腔1112所对应的空间均是变化的。其中,由进水口112进入第一分水腔1111的液体的压力要大于由回水口113进入第二分水腔1112的液体的压力(由于液体流动的压降损失)。因此,第一分水腔1111可视为高压腔,而第二分水腔1112可视为低压腔。
请结合图2及图7,在某些实施方式中,分水阀12具有第一挡片121。第一档片121能够在分水阀12转动时打开或关闭第一出水口114。例如,在图2所示的例子中,第一档片121随分水阀12转动而与第一出水口114错开以连通进水口112及第一出水口114。又如,在图7所示的例子中,第一档片121关闭第一出水口114,以防止液体由第一出水口114进入加热装置40。可以理解,第一挡片121的形状可根据具体情况进行设置,例如可呈圆形状或椭圆形状等。
请结合图10至图21,在某些实施方式中,第一挡片121开设有通水孔1211,在分水阀12转动时,第一挡片121能够通过通水孔1211连通第一出水口114及第一分水腔1111。这样在通水孔1211不连通第一出水口114时,第一挡片121隔断第一出水口114和第一分水腔1111。可以理解,通水孔1211的开设方式可根据具体情况进行设置。通水孔1211的数目可为多个。例如,在图18所示的例子中,第一挡片121的通水孔1211不连通第一出水口114以关闭第一出水口114。
在某些实施方式中,分水阀12具有分隔挡片122。分隔挡片122将分水腔111分隔为第一分水腔1111和第二分水腔1112。分隔挡片122能够在分水腔111内转动以连通进水口112及第一出水口114或隔断进水口112及第一出水口114。
具体地,分隔挡片122在分水腔111内转动连通进水口112及第一出水口114时,分水阀组件10处于上述的第一状态。分隔挡片122在分水腔111内转动隔断进水口112及第一出水口114时,分水阀组件10处于上述的第二状态。
可以理解,分隔挡片122的形状可根据具体情况进行设置。
在某些实施方式中,分隔挡片122包括挡片本体1221和连接在挡片本体1221的两侧的两个挡片连接片1222(见图14及图15)。两个挡片连接片1222分别贴设分水腔111的内壁1110。挡片连接片1222贴设分水腔111的内壁1110以密封挡片连接片1222和分水腔111的内壁1110之间的间隙,以保证分水阀组件10的分水效果。
可以理解,挡片本体1221与两个挡片连接片1222可采用一体结构,也可采用分体结构。
在某些实施方式中,挡片连接片1222与分水腔111的内壁1110弧形连接。这样密封效果较佳。具体地,挡片连接片1222形成的第一弧形面贴设分水腔111的内壁1110形成的第二弧形面。
在某些实施方式中,分水阀12具有第二挡片123。第二挡片123能够在分水阀12转动时打开或关闭第二出水口115。这样通过第二挡片123随分水阀12转动的位置变化实现第二出水口115的打开或关闭。
具体地,第二挡片123在分水阀12转动打开第二出水口115时,分水腔111内的液体能够由第二出水口115流出。第二挡片123在分水阀12转动关闭第二出水口115时,分水腔111内的液体不会由第二出水口115流出。
在某些实施方式中,第二出水口115的数目为多个,第二挡片123的数目为多个,第二挡片123的数目与第二出水口115的数目相同。如此,可通过转动多个第二挡片123的位置以实现不同的第二出水口115的打开或关闭。
在一些例子中(请结合图2、图4至图7及图9至图18),第二出水口115的数目为两个。第二挡片123的数目为两个。两个第二出水口115间隔设置。两个第二挡片123间隔设置。
在一些例子中,第二出水口的数目为三个。第二挡片的数目为三个。三个第二出水口间隔分布。三个第二挡片间隔分布。此时,分水阀组件10的第二出水口的数量与家用电器200的喷臂30一致。三个第二出水口能够分别与第一喷臂31、第二喷臂32和第三喷臂33对应连接,以实现不同的应用模式。
当然,可以理解,第二出水口的数目也可为4个或5个等,第二挡片的数目也可为4个或5个等,在此不作限制。
请结合图2至图7,在某些实施方式中,分水阀12具有第三挡片126。第三档片126能够在分水阀12转动时打开或关闭回水口113。
例如,在图2所示的例子中,第三档片126打开回水口113以连通回水口113与两个第二出水口115。又如,在图5所示的例子中,第三挡片126关闭回水口113以起到对回水口113更好的封闭效果。
请结合图2至图7,分水阀12具有一个第一挡片121、两个第二挡片123和一个第三挡片126。一个第一挡片121、两个第二挡片123和一个第三挡片126沿分水腔111的周向间隔分布。分隔挡片122将分水腔111分隔为第一分水腔1111和第二分水腔1112。
请结合图8至图22,分水阀12具有一个第一挡片121和两个第二挡片123。分水阀12的顶部形成第一挡片121。第一挡片121具有通水孔1211。两个第二挡片123可拆卸地安装于分水阀12的底部(即固定部124)。两个第二挡片123间隔设置。分隔挡片122连接第一挡片121及固定部124。分隔挡片122将分水腔111分隔为第一分水腔1111和第二分水腔1112。
在图2所示的例子中,在分水阀12转动至如图2所示的位置时,分水阀组件10处于第一模式。第一挡片121随分水阀12转动而打开第一出水口114。间隔设置的两个第二挡片123随分水阀12转动而与两个第二出水口(即第二出水口115a和第二出水口115b)错开,这样第二出水口115a和第二出水口115b为打开状态。进水口112和第一出水口114位于第一分水腔1111所在的一侧,而回水口113和两个第二出水口位于第二分水腔1112所在的一侧。第三挡片126随分水阀12转动而与回水口113错开以打开回水口113。
第一分水腔1111连通进水口112及第一出水口114,第一出水口114与加热装置40连通,并且第二分水腔1112同时连通两个第二出水口及回水口113。这时液体由进水口112进入后,经由第一分水腔1111后能够由第一出水口114流出,经由加热装置40加热后,然后又回水口113流回至第二分水腔1112,并能够由两个第二出水口流出,液体的流动方向如图2的箭头所示。这样分水阀组件10能够通过两个第二出水口同时供水。例如,在将分水阀组件10应用于家用电器200时,两个第二出水口中的一个第二出水口115a可连通第三喷臂33,而另一个第二出水口115b可连通第一喷臂31和第二喷臂32。这样在两个第二出水口同时打开时,可实现家用电器200的三个喷臂的同时喷洒加热后的水。
在图10及图11所示的例子中(请结合图21及图22),分水阀组件10处于上述的第一模式。第一分水腔1111通过第一挡片121上的通水孔1211连通进水口112及第一出水口114,第一出水口114能够与加热装置40连通。间隔设置的两个第二挡片123随分水阀12转动而分别打开间隔设置的两个第二出水口115。第二分水腔1112同时连通两个第二出水口115及回水口113。液体在分水阀组件10的流动如图10及图11的虚线箭头所示。
请结合图3,在图3所示的例子中,在分水阀12转动至如图3所示的位置时,分水阀组件10处于第二模式。第一挡片121随分水阀12转动而打开第一出水口114。第一分水腔1111连通进水口112及第一出水口114,第一出水口114与加热装置40连通。第三挡片126随分水阀12转动而与回水口113错开,并且阻挡两个第二出水口中的第二出水口115b。两个第二挡片123均与两个第二出水口中的第二出水口115a错开。第二出水口115a与回水口113连通,第二出水口115b与回水口113隔断。第二分水腔1112连通第二出水口115a及回水口113。进水口112和第一出水口114位于第一分水腔1111所在的一侧,而回水口113和两个第二出水口位于第二分水腔1112所在的一侧。
这时液体由进水口112进入后,经由第一分水腔1111后能够由第一出水口114流出,经由加热装置40加热后,然后又回水口113流回至第二分水腔1112,并能够由第二出水口115a流出,液体的流动方向如图3的箭头所示。这样分水阀组件10为通过一个第二出水口115a进行单独供水的模式。在将分水阀组件10应用于家用电器200时,第二出水口115a可连通第三喷臂33,而第二出水口115b可连通第一喷臂31和第二喷臂32。这样切换两个第二出水口的打开或关闭状态,可实现家用电器200的第一喷臂31和第二喷臂32与第三喷臂33的交替喷洒。
在图12至图13所示的例子中(请结合图21及图22),分水阀组件10处于上述的第二模式。第一分水腔1111通过第一挡片121上的通水孔1211连通进水口112及第一出水口114,第一出水口114能够与加热装置40连通。间隔设置的两个第二挡片中的第二挡片123a随分水阀12转动而打开第二出水口115a,间隔设置的两个第二挡片中的第二挡片123b随分水阀12转动而关闭第二出水口115b。第二出水口115b与回水口113隔断。第二分水腔1112连通第二 出水口115a及回水口113。液体在分水阀组件10的流动如图12至图13的虚线箭头所示。
在图4所示的例子中,在分水阀12转动至如图4所示的位置时,分水阀组件10处于第三模式。第一挡片121随分水阀12转动而打开第一出水口114。第一分水腔1111连通进水口112及第一出水口114,第一出水口114与加热装置40连通。第三挡片126转动而与回水口113错开,以打开回水口113。两个第二挡片中的第二挡片123b随分水阀12转动而阻挡两个第二出水口中的第二出水口115a。第二出水口115a与回水口113隔断。第二挡片123a和第二挡片123b均与第二出水口115b错开,以打开第二出水口115b。第二出水口115b与回水口113连通。第二分水腔1112连通第二出水口115b及回水口113。进水口112和第一出水口114位于第一分水腔1111所在的一侧,而回水口113和两个第二出水口位于第二分水腔1112所在的一侧。
这时液体由进水口112进入后,经由第一分水腔1111后能够由第一出水口114流出,经由加热装置40加热后,然后又回水口113流回至第二分水腔1112,并能够由第二出水口115b流出,液体的流动方向如图4的箭头所示。这样分水阀组件10为通过一个第二出水口115b进行单独供水的模式。
在图14至图15所示的例子中(请结合图21及图22),分水阀组件10处于上述的第三模式,第一分水腔1111通过第一挡片121上的通水孔1211连通进水口112及第一出水口114,第一出水口114能够与加热装置40连通。间隔设置的两个第二挡片中的第二挡片123a随分水阀12转动而关闭第二出水口115a,间隔设置的两个第二挡片中的第二挡片123b随分水阀12转动而打开第二出水口115b。第二出水口115a与回水口113隔断,第二出水口115b与回水口113连通。第二分水腔1112连通第二出水口115b及回水口113。液体在分水阀组件10的流动如图14至图15的虚线箭头所示。
在图5所示的例子中,在分水阀12转动至如图5所示的位置时,分水阀组件10处于第四模式。分水阀组件10转动至使,第三挡片126隔断回水口113,分隔挡片122隔断进水口112和第一出水口114,第一出水口114和回水口113均被分隔挡片122与进水口112隔断,从而实现进水口112与第一出水口114、加热装置40之间流路的阻断,,并且,两个第二挡片123均与两个第二出水口115错开,以使第一分水腔1111连通进水口112及两个第二出水口115。。进水口112和两个第二出水口115位于第一分水腔1111所在的一侧,而回水口113和第一出水口114位于第二分水腔1112所在的一侧。
这时液体由进水口112进入后,经由第一分水腔1111后能够直接由两个第二出水口115流出,不经由加热装置40加热,液体的流动方向如图5的箭头所示。这时分水阀组件10也能够通过两个第二出水口115同时供水。在将分水阀组件10应用于家用电器200时,两个第二出水口115中的一个第二出水口115可连通第三喷臂33,而另一个第二出水口115可连通第一喷臂31和第二喷臂32,并且加热装置40被旁通掉,由进水口112进入的水能够不经回水口113而直接由第二出水口115排出。这样在两个第二出水口115同时打开时,可实现家用电器200的三个喷臂的同时喷洒不经由加热装置40加热的水,可有效减少洗碗机非加热时段的流动阻力,进一步降低洗碗机能耗。
在图16至图17所示的例子中(请结合图21及图22),分水阀组件10处于上述的第四模式。分水阀12转动至使,第一挡片121上的通水孔1211不连通进水口112及第一出水口114,分隔挡片122隔断进水口112和第一出水口114,第一出水口114和回水口113均被分隔挡片122与进水口112隔断。间隔设置的两个第二挡片123均与两个第二出水口115错开,以使第一分水腔1111连通进水口112及两个第二出水口115。第一分水腔1111连通进水口112及两个第二出水口115。液体在分水阀组件10的流动如图16至图17的虚线箭头所示。
在分水阀12转动至如图6所示的位置时,分水阀组件10处于第五模式。分水阀组件10转动至使,第一挡片121关闭第一出水口114,分隔挡片122隔断进水口112和第一出水口114,从而实现进水口112与第一出水口114、加热装置40之间流路的阻断。并且,两个第二挡片中的第二挡片123b阻挡两个第二出水口中的第二出水口115b,第一挡片123a和第二挡片123b均与两个第二出水口中的第二出水口115a错开,以使第一分水腔1111连通进水口112及第二出水口115a。第二出水口115b由第二挡片123b阻挡而与进水口112隔断。由于分隔挡片122使第一出水口114和回水口113位于低压的第二分水腔1112一侧,并使进水口112和两个第二出水口位于高压的第一分水腔1111一侧,这样能够完全隔断进水口112与第一出水口114、加热装置40之间流路。
这时液体由进水口112进入后,经由第一分水腔1111后能够直接由第二出水口115b流出,不经由加热装置40加热,液体的流动方向如图6的箭头所示。这样分水阀组件10为通过一个第二出水口115a进行单独供水的模式。在将分水阀组件10应用于家用电器200时,第二出水口115a可连通第三喷臂33,而第二出水口115b可连通第一喷臂31和第二喷臂32,并且加热装置40被旁通掉,由进水口112进入的水能够不经回水口113而直接由第二出水口115a排出。这样切换两个第二出水口的打开或关闭状态,可实现家用电器200的第一喷臂31和第二喷臂32与第三喷臂33的交替喷洒不经由加热装置40加热的水,可有效减少洗碗机非加热时段的流动阻力,进一步降低洗碗机能耗。在图18至图19所示的例子中(请结合图21及图22),分水阀组件10处于上述的第五模式,分水阀12转动至使,第一挡片121上的通水孔1211不连通进水口112及第一出水口114,分隔挡片122隔断进水口112和第一出水口114,第一出水口114和回水口113均被分隔挡片122与进水口112隔断。间隔设置的两个第二挡片中的第二挡片123b关闭两个第二出水口中的第二出水口115b以隔断第二出水口115b和第一分水腔1111,两个第二挡片中的第二挡片123a打开两个第二出水口中的第二出水口115a以连通第二出水口115a和第一分水腔1111及进水口112。液体在分水阀组件10的流动如图18至图19的虚线箭头所示。
在分水阀12转动至如图7所示的位置时,分水阀组件10处于第六模式,分水阀组件10转动至使,第一挡片121关闭第一出水口114,分隔挡片122隔断进水口112和第一出水口114,从而实现进水口112与第一出水口114、加热装置40之间流路的阻断。并且,两个第二挡片中的第二挡片123a阻挡两个第二出水口中的第二出水口115a,第一挡片123a和第二挡片123b均与两个第二出水口中的第二出水口115b错开,以使第一分水腔1111连通进水口112及第二出水口115b。第二出水口115a由第二挡片123a阻挡而与进水口112隔断。由于第一挡片121阻挡第一出水口114,因此,即使回水口113处于高压的第一分水腔111一侧,进水口112流出的液体也不会流经加热装置40。
这时液体由进水口112进入后,经由第一分水腔1111后能够直接由第二出水口115a流出,不经由加热装置40加热,液体的流动方向如图7的箭头所示。这样分水阀组件10为通过一个第二出水口115a进行单独供水的模式。
可以理解,在第二出水口的数目为三个,并且第二挡片的数目为三个时。在家用电器200需要通过加热装置40进行加热时(即加热模式),分水阀组件10的三个第二出水口能够是仅一个第二出水口与家用电器200对应的一个喷臂实现连通,也能够是其中的两第二出水口与家用电器200对应的两个喷臂实现连通,也能够是三个第二出水口均与家用电器200对应的三个喷臂实现连通。即,在加热模式中,分水阀组件10能够实现7中不同模式的切换。
在家用电器200不需要通过加热装置40进行加热时(即非加热模式),分水阀组件10的三个第二出水口也能够是仅一个第二出水口与家用电器200对应的一个喷臂实现连通,也能够是其中的两第二出水口与家用电器200对应的两个喷臂实现连通,也能够是三个第二出水口均与家用电器200对应的三个喷臂实现连通。即,在非加热模式中,分水阀组件10也能够实现7中不同模式的切换。在某些实施方式中,分水阀12包括固定部124。第二挡片123可拆卸地安装于固定部124。这样便于第二挡片123的安装及拆卸。在本实施方式中,分隔挡片122固定连接固定部124。较佳地,分隔挡片122和固定部124为一体结构。分隔挡片122和第二挡片123分别位于固定部124的两侧。在分水阀12转动时,分隔挡片122和固定部124沿分水腔111的周向转动,第一分水腔1111和第二分水腔1112随着分隔挡片122的转动而变化。第二挡片123随着固定部124转动,以实现打开或关闭第二出水口115。在图12所示的例子中,在水压的作用下,第二挡片123能够受压而实现对第二出水口115的密封。当然,可以理解,在其他例子中,第二挡片能够在重力作用下而密封第二出水口,并能够受压而实现打开第二出水口。
在某些实施方式中,壳体11开设有通道13(见图11)。通道13连通第二出水口115。第二挡片123包括底板1231和自底板1231向上延伸的第一配合部1232(见图21)。固定部124形成有与第一配合部1232配合的第二配合部1241。第二挡片123能够在分水阀12转动时通过底板1231打开或关闭通道13的入口131以打开或关闭第二出水口115。
在图20所示的例子中,第一配合部1232为自底板1231向上延伸的凸片。第二配合部1241为形成在固定部124的侧部的通槽。凸片能够穿设通槽以使第一配合部1232可拆卸地安装于第二配合部1241。并且,凸片能够在通槽中上下活动。
在图20及图21所示的例子中,分水阀12整体基本呈圆柱体状。固定部124呈环状。第二挡片123的数目为两个。两个第二挡片123间隔安装于固定部124并能够随着固定部124沿分水腔111的周向运动。并且,底板1231基本呈扇形状。与第一配合部1232相背的底板1231的一侧形成有密封面1233。在水压的作用下,底板1231受压而能够通过密封面1233实现对通道13的入口131的密封以密封第二出水口115。
在某些实施方式中,分水阀组件10包括驱动机构14。驱动机构14连接分水阀12。驱动机构用于驱动分水阀12转动。
具体地,驱动机构14包括驱动部141和传动部15。传动部15连接驱动部141和分水阀12。驱动部141用于驱动传动部15转动以带动分水阀12转动。其中,传动部15可根据具体情况进行设置,例如可采用齿轮啮合的传动方式、或皮带的传动方式、或者联轴器的传动方式。
在某些实施方式中,分水阀组件10包括传感器16。传动部15包括传动件151,传感器16用于检测传动件151的位置。这样能够根据传感器16检测到的传动件151的位置确定分水阀12的转动状态,继而能够通过传动件151实现对分水阀12的转动控制,以通过控制分水阀12的转动来精确实现分水阀组件10的不同连通状态的切换。其中,传动件151例如可为传动齿轮。
在某些实施方式中,驱动部141包括电机142。分水阀12包括驱动杆125。驱动杆125由分水阀12的顶部向下延伸。分水阀12通过驱动杆125连接传动件151。
在本实施方式中,。驱动杆125由分隔挡片122向下延伸。固定部124围绕驱动杆125。分水阀12通过驱动杆125连接传动件151。其中驱动杆125可通过卡接的方式连接传动件151。电机142用于驱动传动件151转动以带动驱动杆125转动。
在本实施方式中,第一挡片121、驱动杆125、分隔挡片122和固定部124为一体结构,这样便于加工,并且分水阀12整体的稳定性更佳。
可以理解,为了驱动部141和传动部15运行的稳定性,可设置固定盖板19,并使电机142和传动件151分别设置于固定盖板19相背的两侧,电机142的转轴穿设固定盖板19而与传动件151连接。
在某些实施方式中,壳体11包括下壳17和上壳18。下壳17连接上壳18。其中,下壳17与上壳18的连接方式可根据具体情况进行设置。
在某些实施方式中,下壳17开设有进水口112、回水口113和第二出水口115。上壳18开设有第一出水口114。
在本实施方式中,下壳17内限定出分水腔111。分水腔111的上端敞开。下壳17上分别开设有进水口112、回水口113和第二出水口115。上壳18设置于下壳17的上端并封闭分水腔111。上壳18开设有第一出水口114。其中,上壳18可通过可拆卸的方式安装于下壳17的上端,而进水口112、回水口113和第二出水口115能够开设在下壳11的侧壁或者底壁或者顶壁上,这可根据具体情况进行设置。

下面参考图23-图28描述根据本申请实施例的洗碗机100。如图23-图28所示,根据本申请实施例的洗碗机100,包括:洗涤内胆1、喷淋臂、加热装置3和分水阀4。
洗涤内胆1上设有洗涤出口111,喷淋臂设在洗涤内胆1内,喷淋臂上设有喷淋入口,加热装置3具有加热水入口321和加热水出口322,加热装置3用于对洗涤水进行加热。分水阀4上设有进水口41、第二出水口、第一出水口43和回水口44,进水口41与洗涤出口111相连,第二出水口与喷淋入口相连,第一出水口43与加热水入口321相连,回水口44与加热水出口322相连。
具体而言,洗涤内胆1内限定出洗涤腔,洗涤腔内可以设置支架,用于支撑餐具,喷淋臂设在洗涤内胆1内,喷淋臂上设有喷淋入口,洗涤水通过喷淋入口进入到喷淋臂,再通过喷淋臂上设置的喷嘴喷向餐具,从而对餐具进行清洗。
可选地,喷淋到餐具上的洗涤水可以集中被收集在洗涤内胆1底部的集水槽11内,洗涤出 口111形成在集水槽11底部,洗涤水从该洗涤出口111流出。
洗涤水循环系统还包括洗涤泵5,洗涤泵5的进口与洗涤出口111相连通,洗涤泵5的出口与喷淋入口相连通,从通过洗涤泵5对洗涤水的循环提供动力。
在本申请的实施例中,洗碗机100包括至少两个工作模式,在第一模式时,分水阀4的进水口41与第二出水口相连通,在第二模式时,分水阀4的进水口41与第一出水口43相连通、且回水口44与第二出水口相连通。
换言之,当分水阀4的进水口41与第二出水口相连通时,在洗涤泵5的驱动下,洗涤水从洗涤出口111流出后,依次经进水口41和第二出水口流向喷淋入口,洗涤水从喷淋入口流入到喷淋臂内进行喷淋,由此在第一模式下,洗涤水不流经加热装置3,洗涤水不会被加热,第一模式可以被称为非加热模式。其中,在第一模式下,加热装置3可以关闭,这样可以节约能源;当然加热装置也可以根据需要开启,进而可以利用加热装置对其他设备、空间等进行加热,例如可以开启加热装置对洗涤内胆1的内部空间进行烘干。
此外,当分水阀4的进水口41与第一出水口43相连通,且回水口44与第二出水口相连通时,在洗涤泵5的驱动下,洗涤水从洗涤出口111留出后,依次经进水口41、第一出水口43流向加热装置3的加热水入口321,洗涤水从加热水入口321流向加热装置3内,并且被加热成为高温洗涤水,高温洗涤水再从加热水出口322流出,并依次经回水口44和第二出水口流向喷淋入口,高温洗涤水从喷淋入口流入到喷淋臂内进行喷淋,由此在第二模式下,洗涤水流经加热装置3,此时可以启动加热装置3对洗涤水进行加热升温,从而洗碗机100进行高温洗涤模式,这样可以提高清洗效果。其中,第二模式可以被成为加热模式。
根据本申请实施例的洗碗机100,通过设置分水阀4,从而可以实现在不同的洗涤模式下对洗涤水的切换,在非加热模式下,洗涤水不流经加热装置3,这样不仅可以在一定程度上降低非加热时段内水流系统内的水流阻力,提高水流流速,加快清洗速度和清洁度,提升系统洗涤性能,而且在非加热模式下,加热装置3启闭和洗涤水的流路可以分别进行单独控制,洗碗机100的使用更加方便。另外,将分水功能集中在一个分水阀4内,从而使得分水结构紧凑,回路管路有所缩短,控制方法简单。
在本申请的一些实施例中,加热装置3包括首尾依次相连以构成制冷剂循环的压缩机31、冷凝器32、节流装置33和蒸发器34。也就是说,根据本申请的一些实施例,洗碗机100为热泵加热式洗碗机,制冷剂在热泵系统内经历压缩、冷凝放热、节流膨胀、蒸发吸热的过程,将低品位的能量转换成高品位热能后,释放于洗涤水中,达到高效、低能耗制热的目的。与传统的电加热相比,热泵制热系统性能系数是一般电加热技术的3-4倍甚至更高。采用热泵制热技术的洗碗机100,节能效果显著,可大幅度降低洗碗机100的使用能耗,是降低洗碗机100使用能耗的有效手段。
进一步地,冷凝器32内限定出第一液体流道和第二液体流道,第一液体流道的两端分别设有加热水入口321和加热水出口322,第二液体流道的两端分别与压缩机31和节流装置33相连通。换言之,冷凝器32和是液-液热交换器,从而可以使冷凝水的加热效率得到提高。
此外,为了提高洗涤水和制冷剂的热交换效率,第一液体流道和第二液体流道可能会设计的比较复杂,从而可能增大第一液体流道的流动阻力,这样将冷凝器32直接接入到原有的洗涤系统流路中,会使得洗碗机100喷淋臂喷射压力下降或者洗涤泵5耗功增大等问题,尤其在非加热时段内。为此,通过利用根据本申请实施例的洗碗机100,通过设置分水阀4,从而可以解决非加热时段内洗涤水流经冷凝器32而造成的流阻大的问题。
这里需要说明的是,在加热模式时,上述的热泵系统开启,从洗涤内胆1内流出的洗涤水可以通过冷凝器进行加热,高温洗涤水进入到喷淋臂内以对洗涤内胆1内的餐具进行高温洗涤,由此提高洗涤效果。
在非加热模式时,上述的热泵系统可以关闭,这样可以节约能源;当然,上述的热泵系统也可以根据需要开启,进而可以利用热泵系统对其他设备、空间进行加热或者冷却,例如可以开启热泵系统,利用冷凝器32对洗涤内胆1的内部空间进行加热烘干,或者可以利用蒸发器34对洗涤内胆1的内部空间进行冷却除湿。
当然本申请并不限于此,根据本申请实施例的加热装置3还可以是电加热,例如可以采用电热丝加热或者厚膜加热技术来实现对循环水的加热。利用电加热对洗涤水进行加热,结构简单,控制简单。
下面将以加热装置3为热泵系统为例进行详细描述。
在本申请的一些实施例中,喷淋臂可以包括多个,第二出水口可以是一个,每个喷淋臂上的喷淋入口均与第二出水口相连通,从而可以使洗涤水从第二出水口流出后,分散到多个喷淋臂内进行喷淋,清洗效果更好。
在本申请的另一些实施例中,喷淋臂可以包括多个,第二出水口包括多个,每个第二出水口与至少一个喷淋臂上的喷淋入口相连通。由此,多个第二出水口与多个喷淋臂进行多种组合,可以满足不同需要的连接结构,进而实现喷淋臂的交替清洗。
具体地,喷淋臂包括多个,第二出水口包括多个,每个第二出水口至少与一个喷淋臂的喷淋入口相连,并且在第一模式时,进水口41选择性地与至少一个第二出水口相连通,这样在非加热模式下,洗涤水可以根据需要流入到一个或者多个喷淋臂内,从而可以完成交替清洗模式。
同理地,喷淋臂包括多个,第二出水口包括多个,每个第二出水口至少与一个喷淋臂的喷淋入口相连,并且在第二模式时,回水口44选择性地与至少一个第二出水口相连通,这样在加热模式下,洗涤水可以根据需要流入到一个或者多个喷淋臂内,从而可以完成交替清洗模式。
这里需要说明的是,喷淋臂的数量和第二出水口的数量可以相等也可以不相等,由此可以根据需要对喷淋臂和第二出水口的连接进行组合。由此在不同的模式下,洗涤水可以通过第二出水口进入到相应的喷淋臂内进行喷淋清洗,清洗模式多样化,洗碗机100的使用更加方便。下面将参考图23-图28对喷淋臂和第二出水口的连接方式,以及在相应的喷淋臂与第二出水口连接方式下,对于分水阀的控制进行说明。
具体而言,下面参考图23-图28描述根据本申请的一个实施例的洗碗机100:
喷淋臂包括:下喷淋臂23、上喷淋臂21和中喷淋臂22,下喷淋臂23在洗涤内胆1内侧的下部,上喷淋臂21设在洗涤内胆1内侧的上部,中喷淋臂22设在洗涤内胆1内侧的中部。由此通过在洗涤内胆1内的上部、中部和下部均设置喷淋臂,从而可以在洗涤内胆1的上部、中部或者下部均可以实现连通。这样在清洗的过程中,下喷淋臂23可以单独进水喷淋,上喷淋臂21和中喷淋臂22可以同时进水喷淋,或上喷淋臂21、中喷淋臂22和下喷淋臂23可以同时进水喷淋,从而实现交替喷淋的效果。
第二出水口包括两个,每个第二出水口与至少一个喷淋臂相连。例如其中一个第二出水口与下喷淋臂23相连,其中另一个第二出水口与上喷淋臂21、中喷淋臂22同时相连。
进一步地,在第一模式时,进水口41与其中一个第二出水口相连通,或者进水口41与其中另一个第二出水口相连通,或者进水口41同时与两个第二出水口相连通;从而,在第一模式时,当进水口41与其中一个第二出水口相连通时,洗涤水可以通过该第二出水口进入到相应的喷淋臂内,当进水口41与其中另一个第二出水口相连通时,洗涤水可以通过该另一个第二出水口进入到另外相应的喷淋臂内,当进水口41同时与两个第二出水口相连通时,洗涤水可以进入到所有的喷淋臂内。从而,根据不同需要,通过使进水口41与不同的第二出水口相连通,从而实现非加热模式下的交替清洗。
也就是说,在非加热模式下,洗涤水不流过加热装置3(冷凝器32),在分水阀4内解决交替洗时序,实现三种非加热模式:上喷淋臂21和中喷淋臂22工作,下喷淋臂23工作,上喷淋臂21、中喷淋臂22和下喷淋臂23同时工作。因此,在非加热模式时,循环洗涤过程并不会因为流经加热装置3(冷凝器32)而造成流动阻力损失,影响喷淋臂压力和洗涤效果。
在第二模式时,回水口44与其中一个第二出水口相连通,或者进水口41与其中另一个第二出水口相连通,或者进水口41同时与两个第二出水口相连通;从而,在第二模式时,当回水口44与其中一个第二出水口相连通时,高温洗涤水可以通过该第二出水口进入到相应的喷淋臂内,当回水口44与其中另一个第二出水口相连通时,高温洗涤水可以通过该另一个第二出水口进入到另外相应的喷淋臂内,当回水口44同时与两个第二出水口相连通时,高温洗涤水可以进入到所有的喷淋臂内。从而,根据不同需要,通过使回水口44与不同的第二出水口相连通,从而实现加热模式下的交替清洗。
也就是说,在加热模式下,洗涤水流经加热装置3(冷凝器32),在分水阀4中进行流路切换,洗涤循环水经过加热装置3(冷凝器32)加热后,流回分水阀4,并实现三种加热模式:上喷淋臂21和中喷淋臂22工作,下喷淋臂23工作,上喷淋臂21、中喷淋臂22和下喷淋臂23同时工作。因此,可以实现加热过程中的全时序内的交替洗涤。
下面将参考图23-图28的不同示例,对该实施例进行详细描述。
如图23-图28所示,根据本申请实施例的洗碗机100,包括:洗涤内胆1、洗涤泵5、上喷淋臂21、中喷淋臂22、下喷淋臂23、加热装置3和分水阀4。洗涤内胆1的底壁设有集水槽11。
加热装置3包括压缩机31、节流装置33、冷凝器32、蒸发器34,进一步地,压缩机31、冷凝器32、节流装置33、蒸发器34通过管路依次连接成一个密闭的循环系统,制冷剂在密闭的管路系统中循环流动。
分水阀4可以包括阀体外壳、阀片、电机及阀片传动机构。所述阀体外壳上设有进水口41、第二出水口、第一出水口43和回水口44,其中第二出水口包括两个,即在图23-图28中,位于图纸左侧的第二出水口42a和位于右侧的第二出水口42b。
进一步地,所述的洗涤泵5通过管路连接,洗涤泵5进口与集水槽11相连通,洗涤泵5出口与分水阀4的进水口41相连通。
进一步地,所述的上喷淋臂21和中喷淋臂22置于内胆内,而两个喷淋臂的喷淋入口合成一路,上喷淋臂21的喷淋入口211和中喷淋臂22的喷淋入口221通过管路连接后,与分水阀4的第二出水口(例如图23-图28中位于右侧的第二出水口42b)连通。
进一步地,所述的下喷淋臂23置于内胆内,下喷淋臂23的喷淋入口231通过管路连接与分水阀4的另外一个第二出水口(例如图23-图28中位于左侧的第二出水口42a)连通。
进一步地,所述加热装置3的冷凝器32的加热水入口321通过管路与分水阀4的第一出水口43相连通,加热水出口322通过管路与分水阀4的回水口44相连通。
在上述的流路连接下,由洗涤泵5可将集水槽11内的洗涤水不断循环输送到冷凝器32和各个喷淋臂,从而达到对餐具清洗的目的。而通过控制程序,控制分水阀4阀片的转动角度,可实现以下的六种模式:
如图23所示,当阀片将进水口41和位于左侧的第二出水口42a连通,将第一出水口43、回水口44、位于右侧的第二出水口42b阻断时,洗涤泵5输送的清水直接送至下喷淋臂23,从而洗碗机100实现非加热情况下的下喷淋臂23喷淋清洗模式;
如图24所示,当阀片将进水口41和位于右侧的第二出水口42b连通,将第一出水口43、回水口44、位于左侧的第二出水口42a阻断时,洗涤泵5输送的清水同时送至上喷淋臂21和中喷淋臂22,从而洗碗机100实现非加热情况下的上喷淋臂21和中喷淋臂22同时喷淋清洗模式;
如图25所示,当阀片将进水口41和左侧的第二出水口42a连通,并且将进水口41和位于右侧的第二出水口42b连通,第一出水口43、回水口44阻断时,洗涤泵5输送的清水同时送至上喷淋臂21、中喷淋臂22和下喷淋臂23,从而洗碗机100实现非加热情况下的上喷淋臂21、中喷淋臂22和下喷淋臂23同时喷淋清洗模式;
进一步地,当阀片将进水口41和回水口44连通,洗碗机100进入冷凝器32加热模式,此时进水口41、回水口44的连通通道与其他接口的连通通道相隔断。
如图26所示,在加热模式下,阀片将连通进水口41和第一出水口43连通,并且将回水口44和位于左侧的第二出水口42a连通,阻断位于右侧的第二出水口42b时,洗碗机100可实现加热情况下的下喷淋臂23喷淋清洗模式;
如图27所示,在加热模式下,阀片将进水口41和第一出水口43连通,并且将回水口44和位于右侧的第二出水口42b连通,阻断位于左侧的第二出水口42a,洗碗机100可实现加热情况下喷淋臂23、上喷淋臂21和中喷淋臂22的喷淋清洗模式;
如图28所示,在加热模式下,阀片将进水口41和第一出水口43连通,并且将回水口44与位于左侧的第二出水口42a连通,同时将回水口44与位于右侧的第二出水口42b连通,洗碗机100可实现加热情况下、上喷淋臂21、中喷淋臂22和下喷淋臂23同时喷淋清洗模式。
综上,本申请提出的洗碗机100,在非加热时段,水流不流经加热装置3(冷凝器32),可降低在非加热时段内水流系统内阻力压降,提升系统洗涤性能。而在加热时段,洗碗机100仍能采用不同喷臂的交替洗方式,可有效降低系统水耗。另外,系统内将分水功能完全集中在同一个分水阀4内解决,结构紧凑,回路管路有所缩短,控制方法简单。
下面描述根据本申请的第二个实施例:
根据本申请实施例的洗碗机100,包括上喷淋臂21、中喷淋臂22、下喷淋臂23。上喷淋臂21的喷淋入口211和中喷淋臂22的喷淋入口221不合并,第二出水口包括三个,三个第二出 水口分别与下喷淋臂23的喷淋入口231、上喷淋臂21的喷淋入口211和中喷淋臂22的喷淋入口221相连。从而分水阀4可以实现六通六路的方式,从而形成非加热模式时的七种交替洗模式:下喷淋臂23喷淋清洗模式,中喷淋臂22喷淋清洗模式,下喷淋臂23喷淋清洗模式,上喷淋臂21、中喷淋臂22同时喷淋清洗模式,上喷淋臂21、下喷淋臂23同时喷淋清洗模式,下喷淋臂23、中喷淋臂22同时喷淋清洗模式,上喷淋臂21、中喷淋臂22、下喷淋臂23同时喷淋清洗模式。同理地,在加热模式下,也可以实现上述七种交替洗模式,由此该实施例中,共具有十四种模式的交替洗。
在该实施例中的分水阀4的结构会更加复杂,但仍可以实现上述的技术效果,即在非加热时段,水流不流经加热装置3(冷凝器32),可降低在非加热时段内水流系统内阻力压降,提升系统洗涤性能。而在加热时段,洗碗机100仍能采用不同喷臂的交替洗方式,可有效降低系统水耗。另外,系统内将分水功能完全集中在同一个分水阀4内解决,结构紧凑,回路管路有所缩短,控制方法简单。
下面描述根据本申请的第三个实施例:
根据本申请实施例的洗碗机100,包括上喷淋臂21、中喷淋臂22、下喷淋臂23。分水阀4中的第二出水口为一个,上喷淋臂21的喷淋入口211、中喷淋臂22的喷淋入口221、下喷淋臂23的喷淋入口231合并接入分水阀4的第二出水口中,其中分水阀4采用五通五路的形式,从而可构成加热上喷淋臂21、中喷淋臂22、下喷淋臂23同时喷淋清洗模式,非加热上喷淋臂21、中喷淋臂22、下喷淋臂23同时喷淋清洗模式,此时分水阀4的设计会得到进一步简化,可实现降低非加热时段内水流系统内阻力压降的目的。
下面描述根据本申请的第四个实施例:
根据本申请实施例的洗碗机100,包括上喷淋臂21、中喷淋臂22、下喷淋臂23中的任意两个喷淋臂,第二出水口也是两个,两个第二出水口分别与两个喷淋臂相连,从而可以实现两个喷淋臂在加热、非加热模式下的交替洗模式。举例来讲:
洗碗机100的洗涤内胆1内可以采用只设置下喷淋臂23、中喷淋臂22,不设置上喷淋臂21的方案,其中第二出水口可以是两个,其中一个第二出水口与下喷淋臂23的喷淋入口231相连,另一个第二出水口与中喷淋臂22的喷淋入口221相连,可以实现非加热模式时的三种交替洗模式:上喷淋臂21喷淋清洗模式,中喷淋臂22喷淋清洗模式,上喷淋臂21、中喷淋臂22同时喷淋清洗模式。同理地,在加热模式下,也可以实现上述三种交替洗模式,由此,在本实施例中,共具有六种模式的交替洗。
下面描述根据本申请的第五个实施例:
根据本申请实施例的洗碗机100,包括上喷淋臂21、中喷淋臂22、下喷淋臂23中的任意两个喷淋臂,第二出水口是一个,两个喷淋臂均与该第二出水口相连,从而可以实现加热模式和非加热模式时的双喷淋臂喷淋清洗模式。由此,在本实施例中,共具有两种洗涤模式,即双喷淋臂的加热洗和非加热洗模式。
下面描述根据本申请的第六个实施例:
根据本申请实施例的洗碗机100的洗涤内胆1内可以采用只设置下喷淋臂23、中喷淋臂22或者上喷淋臂21中的一个,其中第二出水口可以是一个,第二出水口与下喷淋臂23、中喷淋臂22或者上喷淋臂21中的一个相连,可以实现加热模式和非加热模式时的单喷淋臂喷淋清洗模式。由此,在本实施例中,共具有两种洗涤模式,即相应喷淋臂的加热洗和非加热洗模式。
因此,根据本申请实施例的洗碗机100,通过设置分水阀4,从而可以实现在不同的洗涤模式下对洗涤水的切换,在非加热模式下,洗涤水不流经加热装置3,这样不仅可以在一定程度上降低非加热时段内水流系统内的水流阻力,提高水流流速,加快清洗速度和清洁度,提升系统洗涤性能,而且在非加热模式下,加热装置3启闭和洗涤水的流路可以分别进行单独控制,洗碗机100的使用更加方便。另外,将分水功能集中在一个分水阀4内,从而使得分水结构紧凑,回路管路有所缩短,控制方法简单。
在本申请中,除非另有明确的规定和限定,第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触,也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且,第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方,或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方,或仅仅表示第一特征水平高度小于第二 特征。
