相关技术中的洗干一体机,洗涤过程中,筒体组件内的洗涤剂容易产生大量泡沫,由于干衣循环风道和新风风道均与筒体组件连通,泡沫可能进入干衣循环风道和新风风道内。干衣循环风道基本不与外界连通,也就是说,干衣循环风道为封闭式通道,进入干衣循环风道内的泡沫基本上不会溢出至洗干一体机外;而新风风道与外界大气连通,也就是说,新风风道为开放式通道,进入新风风道的泡沫能够溢出至洗干一体机外,例如,通过新风风道外溢的泡沫可 能会堆积至洗干一体机的外表面,甚至掉落至地面等其他结构上,这样不仅带来安全风险,还会造成用户困扰,用户体验差,降低用户对产品的评价。一种处理方法是在新风风道内设置格栅,利用格栅消泡,虽然格栅可以在一定程度上抑制泡沫的外溢,但是,在泡沫量较大的情况下,仍然存在泡沫外溢的问题,除此之外,由于格栅会阻挡气流的流动,因此,格栅还会明显影响新风风道的进风量。
本申请实施例提供的洗干一体机,请参阅图1和图2,洗干一体机包括筒体组件200、本申请任一项实施例中的冷凝器组件、加热风道300、加热器和排风风道400,筒体组件200形成有衣物处理腔200a。衣物处理腔200a用于盛放衣物。
请参阅图3至图6,本申请实施例提供的冷凝器组件包括冷凝器110和防溢泡器120,冷凝器110形成有冷凝风道110a和新风风道110b,新风风道110b与冷凝风道110a连通,防溢泡器120具有进气口120a和弹性口120b,进气口120a的周围部位与新风风道110b密封连接,且进气口120a与外界连通,弹性口120b位于新风风道110b内,使得来自冷凝风道110a的泡沫能够驱使弹性口120b闭合,来自进气口120a的外界气流能够驱使弹性口120b扩张。
冷凝风道110a的进风口110a’与衣物处理腔200a连通,加热风道300连通冷凝风道110a的出风口110a”和衣物处理腔200a,加热器设置于加热风道300内。加热器用于加热流经加热风道300的气流。衣物处理腔200a、冷凝风道110a和加热风道300共同构成循环风道,循环气流能够在循环风道内循环流动,循环气流先流经冷凝风道110a,再流经加热风道300。示例性的,衣物处理腔200a内的干热气流与潮湿衣物接触后成为湿热气流,湿热气流通过冷凝风道110a的进风口110a’进入冷凝器110内,经过冷凝器110冷凝除湿后成为干冷气流,干冷气流通过冷凝风道110a的出风口110a”进入加热风道300内,经过加热器加热之后成为干热气流,干热气流再次进入衣物处理腔200a内,如此,通过循环风道内的循环气流烘干衣物。
请参阅图1和图2,排风风道400连通衣物处理腔200a和外界。由于外界 气流可以通过新风风道110b进入冷凝风道110a内,再通过加热风道300进入衣物处理腔200a中,衣物处理腔200a中多余的气量可以通过排风风道400排出至洗干一体机外。
本申请实施例提供的冷凝器组件,一方面,湿热气流进入冷凝风道110a内,通过冷凝器110冷凝除湿后形成干冷气流再回流至衣物处理腔200a内。新风风道110b设置于冷凝器110上,外界气流也可以通过冷凝风道110a送入衣物处理腔200a内,不仅可以节约管道,减少管件,节约洗干一体机内的安装空间,还能使得循环气流和外界气流更好地混合后再进入衣物处理腔200a内,从而提高烘干效率,改善烘干效果。另一方面,由于进气口120a的周围部位与新风风道110b密封连接,避免进气口120a的周围部位和新风风道110b之间的间隙流通外界气流和泡沫。在烘干过程中,外界气流通过进气口120a进入弹性口120b内,外界气流的作用力驱使弹性口120b扩张,即外界气流驱使弹性口120b的面积扩大,提高外界气流的进风量。在洗涤过程中,衣物处理腔200a的泡沫可能进入冷凝风道110a内,来自冷凝风道110a的泡沫进入新风风道110b内,随着泡沫逐渐填充新风风道110b,泡沫产生的作用力驱使弹性口120b闭合,从而抑制泡沫外溢。这样,通过泡沫控制弹性口120b闭合、外界气流控制弹性口120b扩张,实现新风单向流入新风风道110b内,结构简单、成本低且可靠性好,不仅可以减少电磁阀或其他电控件启闭新风风道110b,还能够提高外界气流的进风量,兼顾成本和烘干效率。
本申请实施例提供的洗干一体机,在洗涤过程中,衣物处理腔200a内存在的泡沫可能通过冷凝风道110a的进风口110a’进入冷凝风道110a内,由于衣物处理腔200a、加热风道300和冷凝风道110a大致构成密闭式的循环风道,进入循环风道的泡沫基本不会溢出至洗干一体机外;而新风风道110b连通外界,来自冷凝风道110a的泡沫堆积至新风风道110b内,泡沫挤压弹性口120b以驱使弹性口120b闭合,这样,泡沫基本不会溢出弹性口120b,也就不会溢出至洗干一体机外。在烘干过程中,外界气流驱使弹性口120b扩张,这样,弹性口120b不会干涉气流流动,在一定程度上避免影响新风的进风量。
新风风道110b和循环风道的具体工作方式不限,示例性的,一些实施例中,在烘干过程中,新风风道110b、排风风道400和加热风道300可以保持导通的状态,即在烘干过程的开始阶段和持续烘干阶段,新风风道110b持续进风,排风风道400持续排风,加热风道300持续通风。在整个烘干过程中,可以一边通入新风,同时流通循环气流。如此设计,在烘干过程的开始阶段,由于衣物含水量较高,与潮湿衣物接触后的湿热气流不仅含水量较高,还容易存在异味,这时,可以通过排风风道400排出含水量较高且可能存在异味的湿热气流,通过新风风道110b引入新风,保持较大的烘干气流的风量,较为快速地降低气流中的总含水量,提升干衣效率,提高烘干效果,解决气流中存在异味的问题;进入持续烘干阶段时,持续通入新风,同时循环风道提供循环气流烘干衣物,不仅能够降低能耗,提升烘干效率,还能够均衡排出洗干一体机的温度和含水量,不会显著影响室内环境的温度和湿度,降低对室内环境的影响,兼顾烘干效率和环境友好。
一实施例中,请参阅图5,泡沫挤压弹性口120b的外表面,以使得弹性口120b的内表面贴合实现闭合;请参阅图6,外界气流推动弹性口120b的内表面,以使得弹性口120b的过流断面的面积增大实现扩张。也就是说,泡沫和外界气流分别推动弹性口120b的周围部位发生弹性形变,以实现弹性口120b的闭合或扩张。
一实施例中,请参阅图8,在防溢泡器120处于自然状态下,进气口120a的面积大于弹性口120b的面积。这样,进气口120a的面积相对较大,以保证外界较大量的气流顺畅进入弹性口120b所在处。弹性口120b的面积相对较小,以便弹性口120b在泡沫的作用力较小时即可较为迅速地闭合。
需要说明的是,所述的防溢泡器120处于自然状态是指防溢泡器120未受到泡沫和外界气流的作用力的状态。这样,弹性口120b保持自然形态即未形变的形态。
一实施例中,请参阅图8,防溢泡器120形成有连通进气口120a和弹性口120b的气流通道120c,在防溢泡器120处于自然状态下,气流通道120c的过 流断面的面积从进气口120a向弹性口120b逐渐减小。气流通道120c的过流断面的面积从进气口120a向弹性口120b逐渐减小,不仅可以起到导流作用,还能够加快气流通道120c内的气流流速。
需要说明的是,过流断面是指与总流的所有流线正交的横断面,即垂直于流速簇的面。总流是指由无数元流组成的整个流体。以防溢泡器120为例,进气口120a的过流断面是指进气口120a的垂直于外界气流即流速簇的面。过流断面可以为平面也可以为曲面,例如,当流线簇彼此不平行时,过流断面为曲面;当流线簇为彼此平行直线时,过流断面为平面。
一实施例中,请参阅图7和图8,防溢泡器120包括柔性件121,弹性口120b形成于柔性件121上。柔性件121是指采用柔性材料制备的结构。柔性材料是指能够产生可弯曲、可折叠、可扭转、可压缩和/或可拉伸的弹性形变的材料。因此,利用柔性件121的自身特性实现弹性口120b的闭合或扩张,结构简单。
一些实施例中,柔性材料包括但不限于柔性塑料、柔性橡胶和/或柔性硅胶等等。
一些实施例中,柔性件121形成有多个孔眼,孔眼的目数大于或等于120目。这样,孔眼的尺寸较小,在保证泡沫难以通过孔眼进入柔性件121内的条件下,柔性件121的重量较轻,成本较低。
一实施例中,请参阅图8,在防溢泡器120处于自然状态下,弹性口120b可以呈缝隙状。也就是说,在弹性口120b处于自然状态下,即弹性口120b未受到来自泡沫和外界气流的作用力的情况下,弹性口120b呈缝隙状开口。换句话说,在防溢泡器120处于自然状态下,弹性口120b保持缝隙状开口,这样,在烘干过程中,在风轮处于较小转速,负压较小时,弹性口120b即可扩张,迅速加大弹性口120b的面积;在洗涤过程中,新风风道110b内的泡沫量较少时,弹性口120b即可闭合。如此设计,在弹性口120b受到泡沫或外界气流的作用力较小时,弹性口120b即可实现闭合或扩张,不仅响应速度快,可靠性好,还便于生产制造。
示例性的,一实施例中,柔性件121为一体注塑成型结构。弹性口120b呈缝隙状开口时,模具上用于制造柔性件121的型腔更易设计,且更易向型腔内注塑成型,工艺要求更低,制造成本低。
一实施例中,在防溢泡器120处于自然状态下,弹性口120b可以保持闭合。这样,在洗涤过程中,新风风道110b内的泡沫量进一步挤压弹性口120b,使得弹性口120b更紧密地闭合;在烘干过程中,在风轮达到较大转速时,弹性口120b扩张,进一步提高可靠性。
一实施例中,请参阅图8,柔性件121包括两个倾斜壁1211,两个倾斜壁1211间隔布置,且两个倾斜壁1211的一端相对倾斜,两个倾斜壁1211共同限定的尖端为弹性口120b。一方面,倾斜壁1211起到导流作用,以将进入柔性件121内的外界气流快速导向弹性口120b。另一方面,来自冷凝风道110a的泡沫挤压倾斜壁1211的外表面,以使两个倾斜壁1211的内表面紧密贴合,实现弹性口120b闭合;来自进气口120a的外界气流挤压倾斜壁1211的内表面,以驱使两个倾斜壁1211相互远离,实现弹性口120b扩张。
一实施例中,请参阅图7和图8,倾斜壁1211为平板状结构,即在柔性件121处于自然状态下,倾斜壁1211的外表面和内表面均为平面。这样,倾斜壁1211的结构简单,便于制造。
一实施例中,请参阅图7,柔性件121包括两个平行壁1212,两个平行壁1212分别封闭两个倾斜壁1211的垂直于气流流动方向上的两个间隙。如此,柔性件121的外观形状大致呈楔形结构,楔形结构的尖端为弹性口120b。
一实施例中,请参阅图7至图9,防溢泡器120包括支撑框122,进气口120a形成于支撑框122上,柔性件121与支撑框122密封套接。支撑框122的结构强度较好,不仅能够有效保持进气口120a的大小,还能够有效支撑柔性件121,以便来自进气口120a的外界气流顺畅进入柔性件121的内部空间,从而流动至弹性口120b处。
一实施例中,请参阅图7和图8,柔性件121为中空结构,柔性件121的内部空间为气流通道120c。这样,防溢泡器120结构简单,来自进气口120a 的气流能够通过柔性件121的内部空间迅速流动至弹性口120b,气路较短。
一实施例中,请参阅图7和图8,两个倾斜壁1211和两个平行壁1212共同围设形成中空的楔形结构,楔形结构的大头端密封地套设于支撑框122的进气口120a的外周围。这样,支撑框122能够有效支撑楔形结构的大头端,以便外界气流顺畅进入楔形结构内,再流动至弹性口120b处。
支撑框122的具体材质不限,支撑框122能够保持形态即可,一些实施例中,支撑框122包括但不限于硬质塑料。
一实施例中,支撑框122可以与新风风道110b通过粘接或焊接等方式实现密封连接。这样,支撑框122与新风风道110b之间的密封性好。另一些实施例中,支撑框122和新风风道110b也可以通过卡接或螺钉连接等可拆卸连接方式连接,可以在支撑框122和新风风道110b之间设置密封圈,以密封支撑框122和新风风道110b之间的间隙,避免漏风或溢泡。
一实施例中,柔性件121与支撑框122可以通过密封胶实现密封套接。这样,可以实现柔性件121与支撑框122之间的快速密封连接。
另一实施例中,柔性件121与支撑框122也可以通过双色注塑一体成型。也就是说,柔性件121与支撑框122可以采用不同的材质一体注塑成型。这样,柔性件121与支撑框122之间连接更牢固,密封性也更好。
一实施例中,请参阅图5、图8和图9,支撑框122包括环形部1221和套接部1222,环形部1221与新风风道110b的进入口的周围部位密封连接,环形部1221的中间开口为进气口120a,套接部1222从环形部1221向新风风道110b的内部延伸,柔性件121密封套设于套接部1222上且位于新风风道110b的内部。如此设计,支撑框122结构简单,环形部1221的结构强度好,便于环形部1221与新风风道110b的进入口密封连接。易变形的柔性件121密封套设于套接部1222上,套接部1222能够有效保持柔性件121呈一定程度的张开状态,以便来自进气口120a的外界气流顺畅进入柔性件121的内部空间。柔性件121设置于新风风道110b的内部,不仅能够避免其他结构或作业人员误触柔性件121,还能够便于新风风道110b内的泡沫挤压柔性件121,以驱使弹性口120b 闭合。
环形部1221的具体形状不限,示例性的,环形部1221的外观形状可以大致呈圆环形、椭圆环形或多边形等等。一实施例中,请参阅图8和图9,环形部1221的形状大致呈四方形,两个倾斜壁1211和两个平行壁1212均与套接部1222密封连接。这样,防溢泡器120结构简单,便于生产制造。
一实施例中,请参阅图5,冷凝风道110a的进风口110a’的高度低于新风风道110b的高度,冷凝风道110a的出风口110a”的高度高于新风风道110b的高度。也就是说,在冷凝器110的高度方向上,新风风道110b位于冷凝风道110a的进风口110a’和冷凝风道110a的出风口110a”之间。这样,便于外界气流和干冷气流更好地混合形成混合气流后,再通过冷凝风道110a出风口110a”流出。
需要说明的是,冷凝器110的高度方向与上下方向一致,冷凝风道110a的进风口110a’所在的一侧为下,冷凝风道110a的出风口110a”所在的一侧为上,这样,冷凝风道110a内的气流大致沿由下至上流动。
一实施例中,请参阅图4和图5,冷凝器110形成有与冷凝风道110a连通的冷媒流道110c,冷媒流道110c的高度低于新风风道110b的高度,且冷媒流道110c的高度高于冷凝风道110a的进风口110a’的高度。也就是说,在冷凝器110的高度方向上,冷媒流道110c位于新风风道110b和冷凝风道110a的进风口110a’之间。在烘干过程中,循环风道和新风风道110b均工作的情况下,湿热气流从进风口110a’进入冷凝风道110a内,由于冷媒流道110c的高度低于新风风道110b,来自冷媒流道110c的冷媒进入冷凝风道110a内,湿热气流先与冷媒接触换热除湿成为干冷气流,干冷气流再与来自新风风道110b的外界气流混合形成混合气流后,混合气流通过出风口110a”流出。这样,混合气流的含水量低且风量大,以便烘干衣物。
一实施例中,请参阅图4和图5,冷凝器110形成有冷媒入口110d和排出口,冷媒入口110d位于冷凝器110的上部位,排出口位于冷凝器110的下部位,冷媒入口110d与冷媒流道110c连通,以将冷媒输送进入冷媒流道110c内。排 出口与冷凝风道110a连通,以排出冷媒和冷凝水。
一实施例中,请参阅图5,冷媒流道110c大致沿冷凝器110的宽度方向延伸,冷媒流道110c的侧壁形成多个连通冷媒流道110c和冷凝风道110a的通孔110e,冷媒通过通孔110e进入冷凝风道110a内。这样,通过通孔110e可以较为均匀地喷洒冷媒,以便冷媒与湿热气流大面积充分接触,提高除湿效率。
需要说明的是,本申请实施例中,多个是指数量为两个以及两个以上。
冷媒的类型不限,示例性的,冷媒包括但不限于水液。用作冷媒的水液与湿热气流具有温度差即可实现换热冷凝,例如,冷媒可以为低温水液,湿热气流包括热空气和气态水,如此,湿热空气和低温水液直接接触,低温水液吸收湿热气流的热量,低温水液的温度升高但是并不足以汽化,湿热气流中的气态水在降温后冷凝为水珠随同水液(冷媒)一起从排出口流出。
需要说明的是,干冷气流是相对湿热气流而言,干冷气流的温度比湿热气流的温度低。本申请实施例中,低温水液的温度可以是室温以及室温以下的温度。
冷凝器110的具体结构不限,一实施例中,请参阅图3和图5,冷凝器110包括出风部111和换热部112,换热部112设置于出风部111的下方,冷凝风道110a从换热部112延伸至出风部111,冷凝风道110a的进风口110a’形成于换热部112上,冷凝风道110a的出风口110a”和新风风道110b均形成于出风部111上。如此,冷凝器110结构简单,湿热气流在换热部112内实现冷凝除湿形成干冷气流,干冷气流进入出风部111以与外界气流混合形成混合气流,混合气流通过出风口110a”流出冷凝器110。这样,风量大且含水量低的干冷气流流出冷凝器110,以提高烘干效率,改善烘干效果。
一实施例中,请参阅图4和图5,换热部112位于出风部111的靠近新风风道110b的一侧。示例性的,换热部112位于出风部111沿冷凝器110的长度方向的一侧。一方面,换热部112和出风部111大致呈L形结构,这样,可以适当延长气流在换热部112和出风部111内的流动路径,以便气流充分换热和混合,提高冷凝效率和气流混合效果。另一方面,换热部112和新风风道110b 位于出风部111的同一侧,换热除湿后的干冷气流能够与外界气流尽快混合。在保证换热效率和混合效果的条件下,冷凝器110的尺寸可以较小,以减少冷凝器110占据的安装空间。
一实施例中,请参阅图5,冷凝风道110a的进风口110a’形成于换热部112远离新风风道110b的侧壁上。示例性的,进风口110a’形成于换热部112沿冷凝器110的长度方向的一个侧壁上。如此可以增加湿热气流在换热部112内的流动路径,适当延长湿热气流与冷媒的接触时长,以便湿热气流能够与冷媒充分接触换热。
需要说明的是,冷凝器110的高度方向、宽度方向和长度方向相互垂直,共同构成三维垂直坐标系。
一实施例中,请参阅图5,冷媒流道110c位于换热部112的靠近新风风道110b的一侧。这样,冷媒与湿热气流相对流动,以增加冷媒与湿热气流的接触时长,提高换热效率。
一些实施例中,洗干一体机包括设置于加热风道300内的风轮。风轮用于驱动气流流动。一方面,风轮转动在加热风道300内形成负压,以驱动衣物处理腔200a内的气流和外界气流进入冷凝风道110a内。另一方面,将风轮设置于加热风道300内,避免风轮占据冷凝风道110a的空间,简化冷凝器110的结构,冷凝风道110a内的流场更加稳定,风阻小。
一些实施例中,风轮位于加热器的沿气流流动方向的上游。也就是说,冷凝除湿后的气流先流经风轮,再流经加热器。这样,避免加热后的干热气流接触风轮。
一些实施例中,洗涤过程中,风轮、加热器和冷凝器110均可以处于非工作状态,即风轮不转动,加热器不加热,冷凝器110不给冷凝风道110a内的气流除湿。衣物处理腔200a内水流与衣物运动,以洗涤衣物。
一些实施例中,烘干过程中,风轮、加热器和冷凝器110均可以处于工作状态,即风轮转动,加热器加热,冷凝器110除湿。
筒体组件200的具体结构不限,一些实施例中,筒体组件200可以包括可 转动地洗涤筒,衣物处理腔200a形成于洗涤筒内。如此,可以通过洗涤筒转动以带动衣物和水流运动,从而洗涤衣物,例如,可以通过洗涤筒的转动,实现衣物的清洁、漂洗和脱水等等。
一些实施例中,请参阅图1和图2,筒体组件200还可以包括套设于洗涤筒外的外桶210,外桶210保持固定。在洗涤和/或烘干过程中,洗涤筒可以转动,以提高洗涤和烘干效率,而外桶210保持固定不动,这样便于在外桶210上设置例如加热风道300、冷凝器110等结构,降低装配难度。
示例性的,一些实施例中,洗涤筒的周向面可以形成流通口,外桶210可以用于盛水,外桶210内的水液可以通过流通口进入或流出洗涤筒。
一些实施例中,请参阅图1和图2,筒体组件200的轴线可以沿水平方向。换句话说,洗干一体机可以为滚动式洗干一体机。示例性的,外桶210和洗涤筒的轴线均沿水平方向,洗涤筒和外桶210均朝前侧开口,这样,用户可以通过洗涤筒和外桶210的前侧开口将衣物投入或取出衣物处理腔200a。
需要说明的是,前是指朝向用户的一侧,后与前相对是指背离用户的一侧。上是指朝天花板的一侧,下与后相对是指背离天花板的一侧。顶与上方向一致,底与下方向一致。
一些实施例中,洗干一体机包括门体,门体能够打开外桶210的前侧开口或密封地关闭外桶210的前侧开口。这样,在需要使用洗干一体机或使用完成后,可以通过门体打开外桶210的前侧开口,以便取放衣物。在洗涤或烘干过程中,门体密封地关闭外桶210的前侧开口,防止水液或气体等从外桶210的前侧开口流出。
一些实施例中,请参阅图1和图2,筒体组件200的轴线沿水平方向,加热风道300设置于外桶210的上表面,加热风道300的下游端口与外桶210的前表面的顶部位连通,冷凝器110位于外桶210的后表面的上部位,冷凝风道110a的进风口110a’与外桶210的后部位连通。衣物处理腔200a内的湿热气流从后方的上侧进入冷凝风道110a内,干热气流从前方的顶侧进入衣物处理腔200a,加热风道300的下游端口和冷凝风道110a的进风口110a’的位置均较高, 在一定程度上避免水液和/或泡沫等进入加热风道300和冷凝风道110a内。在泡沫量较大的情况下,例如洗涤剂添加量过大等情况下,泡沫可能充满整个衣物处理腔200a,过多的泡沫不可避免地进入冷凝风道110a内,泡沫逐渐填充至新风风道110b内,防溢泡器120能有效防止泡沫外溢。
示例性的,一些实施例中,请参阅图1和图2,出风部111设置于外桶210的上方,换热部112贴合外桶210的后表面。这样,冷凝器110不仅能够更稳定地装配在外桶210上,还能够避免冷凝器110占据过多的安装空间。
一些实施例中,请参阅图1和图2,筒体组件200的轴线沿水平方向,排风风道400形成于外桶210的顶部。进一步地,排风风道400位于外桶210的顶部的后侧。一方面,排风风道400的位置较高,衣物处理腔200a内的水液和/或泡沫较难接触排风风道400。另一方面,排风风道400距离加热风道300的下游端口较远,在一定程度上避免干热气流从排风风道400排出。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不仅限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。
