具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本发明,而不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的微气泡发生器100。
根据本发明实施例的微气泡发生器100,如图1及图2所示,包括:溶气罐1和空化件4。溶气罐1内限定出溶气腔10,溶气罐1具有出入水流的入口14和出口15。空化件4设在溶气罐1外并与出口15相连,或者空化件4设在出口15处,空化件4通过空化效应将溶于水中的气体制成气泡。
在溶气罐1内部气压小于进水水压时,微气泡发生器100的入水流速大于出水流速,当溶气罐1内的气压逐渐上升至接近进水水压后,出水流速等于入水流速。水流由入口14注入溶气罐1,在往溶气罐1注入一段时间后溶气腔10内的水位逐渐上升。溶气罐1的入口14位于出口15的上方,因此溶气腔10的水位上升后会很快没过出口15,使出口15处形成水封。在出口15处形成水封后,出口15处仍经空化件4排水,入口14处仍源源不断地进水,因此溶气腔10内水位仍在不断上升,导致水面上方空气空间逐渐减小,从而溶气腔10逐渐升压形成高压腔,当溶气腔10上部空腔形成高压腔后,空气在高压状态下的溶解度大于低压状态下的溶解度,因此溶气腔10内空气于水中的溶解度会大大增加。流向空化件4的水中溶解有大量空气,空化件4能通过空化效应制出大量微气泡,可以用于洗涤等多方面用途。
本发明实施例的方案,是将空气作为一种溶质溶解于水中,即空气以离子形态分散于水分子中。溶解的状态分散空气离子,水分子中空气离子较均匀。此后经空化效应析出的气泡,在形成初期大部分只有纳米级、微米级大小。带有微气泡的水即使在流动到最终洗涤场所后,微气泡相互溶和,得到的大部分微气泡仍能保持在毫米级甚至更小。这种级别的微气泡,其爆破能量能有效传达到毫米级、微米级大小的纤维之间的污渍上,也能传达到洗涤剂微粒上,因此微气泡水用于洗涤时去污能力强,用于溶解洗涤剂时溶解速度快、洗涤剂残留少,而且溶解于水中的空气通常在空化件4中析出不充分,在使用过程中溶解于水中的空气还会慢慢补充微气泡。
溶气罐1上入口14位于出口15的上方,一方面有利于利用液面水封出口15,另一方面入口14进水时水从上方冲向水面,可使水面激荡,同时带入部分高压空气,能增加空气与水的动态接触面积。
本发明实施例的微气泡发生器100,利用溶气腔10出入水流存在流速差,及入口14与出口15的高低差,在出口15处形成水封,使溶气腔10逐渐升压形成高压腔,从而能提高溶气量,然后利用空化件4将高空气浓度水制成高含量微气泡水。微气泡发生器100结构简单,溶气效果好,且成本较低。
在一些实施例中,溶气罐1分体加工,然后装配为一体,这样容易成型,坏品率低。
具体地,如图1至图3所示,溶气罐1包括加液盒体11和第一盖体12,加液盒体11的一端设有开口,第一盖体12与加液盒体11连接配合以封闭开口。第一盖体12上具有出入水流的入口14和出口15,入口14位于出口15的上方。如此设置,微气泡发生器100上水管连接在溶气罐1的同一端,接管非常方便。
溶气罐1包括第二盖体13,加液盒体11的另一端也设有开口,第二盖体13与加液盒体11连接配合以封闭该开口。第二盖体13上设有补气口16,补气口16用于在溶气腔10内空间不足时补足空气。当溶气罐1需要补气时,可将空气泵连接到补气口16处,将高压空气通过补气口16泵入溶气腔10内。
溶气罐1的相对两端是敞开的,第一盖体12和第二盖体13配合在溶气罐1的相对两端,这样溶气罐1一端接管用于接排水,另一端接管用于接气,水气管路分开,方便做密封、绝缘处理。
在一些实施例中,如图2及图5所示,微气泡发生器100还包括密封圈6,密封圈6用于溶气罐1的密封连接。具体地,第一盖体12与加液盒体11之间、第二盖体13与加液盒体11之间均设有密封圈6。第一盖体12、第二盖体13上分别设有用于收容密封圈6的密封槽19,避免密封圈6变形导致与紧固件7发生干涉,便于密封圈6的定位、安装和密封。
第一盖体12与加液盒体11之间通过紧固件7相连,第二盖体13与加液盒体11之间也 通过紧固件7相连。可选地,紧固件7为螺钉等。在其他实施例中,第一盖体12、第二盖体13也可以通过焊接或者胶黏等方式连接在加液盒体11上,也能保证密封性。
如图5所示,第一盖体12上设有定位柱101,如图3所示,加液盒体11上设有定位孔102,定位柱101插接配合在定位孔102内,从而提高装配效率且精密度。如图6所示,第二盖体13上设有定位孔102,加液盒体11上设有与该定位孔102配合的定位柱(未图示)。
第一盖体12与加液盒体11在拼接处通过台阶面接触配合,第二盖体13与加液盒体11在拼接处通过台阶面接触配合,这样不仅连接处接触面积增大了,接触强度也能提高。另外,由于微气泡发生器100使用时内部压力大于外部,拼接处台阶面合理设置下的前提下,可使拼接处越压越紧,从而避免因内部高压导致拼接处裂开、漏气的问题。
在一些实施例中,如图2和图4所示,微气泡发生器100包括挡板3,挡板3位于溶气腔10内。挡板3的设置,使溶气腔10内水花在喷射时可以冲击到挡板3上,增加水气接触面积,而且挡板3能够延长水流在溶气腔10内的停留时间,提高溶气效果。此外,挡板3还可以作为加强结构,增强溶气罐1承压能力。
具体地,挡板3设在加液盒体11和第一盖体12中的至少一个上,也就是说,挡板3可以仅设置在加液盒体11上,挡板3可以仅设置在第一盖体12上,或者加液盒体11和第一盖体12上均设有挡板3。
如图4和图5所示,挡板3设在第一盖体12上,在水平方向上挡板3的至少部分位于入口14和出口15之间,这样挡板3的阻流作用最直接有效。这里提到的挡板3至少部分在水平方向上位于入口14和出口15之间,是指挡板3可以完全位于入口14和出口15之间,挡板3还可以仅部分位于入口14和出口15之间。例如,挡板3可以形成为弧形板或者球面板,此时挡板3仅部分位于入口14和出口15之间。
挡板3将溶气腔10的至少一部分分隔成与入口14连通的气泡溶解区及与出口15连通的水流排出区,气泡溶解区内的水流绕过挡板3进入水流排出区内。这样设置,气泡溶解区和水流排出区都具有一定空间大小,入水有足够空间激发水花,出水的水流阻力不致过大,而且两个空间的划分能尽可能拉长水流流动路径,从而有利于空气的溶解。
入口14位于溶气腔10的上部,出口15位于溶气腔10的下部。挡板3竖向设置,挡板3的底部抵接在溶气腔10的内壁上,避免水流从挡板3下方流向水流排出区。
在图4和图5所示的示例中,挡板3形成为板状,且垂直抵接在溶气腔10的底壁上。由此,不仅能较好阻拦水流激发产生的大气泡流出溶气罐1(避免大气泡内空气尚未溶解于水中就逸出溶气腔10),又能方便生产和制造。板状的挡板3无论是一体形成在溶气罐1上,还是通过插接或者焊接等方式固定到溶气罐1上,都要比曲面板要容易得多。在本发明的其他实施例中,挡板3还可形成为倾斜板、双层中空板,或者能形成为上述提到的弧形板、 球面板等等。
如图3所示,加液盒体11位于溶气腔10的底部设有嵌槽103,挡板3的底部插入配合在嵌槽103内。嵌槽103的设置一方面方便第一盖体12安装定位,另一方面可提高挡板3的强度,还有一方面可以尽量避免水流从挡板3底部绕过挡板3。
如图5所示,挡板3在朝向水流排出区处设有分流筋31,分流筋31一方面可以提高挡板3的强度,另一方面可用来疏导水流流动方向。
在一些实施例中,加液盒体11可以按照安装环境的限制设置形状。在图2和图3的示例中,加液盒体11为长条件,使得微气泡发生器100整体为长条形,容易安装在装置的边角处或者狭缝处等的狭长空间内。由于微气泡发生器100工作时,溶气腔10内侧水压最高可达1.2MPa,因此需要保证加液盒体11的密封性与耐疲劳。
具体地,入口14、出口15和挡板3均设在溶气罐1的长度方向的同一端上,补气口16位于溶气罐1的长度方向的另一端上。
如图2和图3所示,加液盒体11的外表面设有外加强筋17,这样能增加加液盒体11的强度,避免因内部高压而变形、漏气。可选地,外加强筋17可均匀间隔排布,外加强筋17也可横纵交错设置。可选地,外加强筋17的厚度为2-5mm,从而不易折断。
如图3所示,加液盒体11内设有内加强筋18,内加强筋18不仅能提高加液盒体11的强度,而且有利于疏导水流,延长水流流动路径。可选地,内加强筋18的厚度为2-10mm。
加液盒体11为塑料件,外加强筋17、内加强筋18一体形成在加液盒体11上。
加液盒体11的长度在100-350mm之间,加液盒体11的截面宽度尺寸、高度尺寸均在30-200mm。
在一些实施例中,如图1和图2所示,第一盖体12上设有入水管21和出水管22,入水管21与入口14相连,出水管22与出口15相连,入水管21和出水管22位于溶气腔10外部,二者的设置可方便接管。入水管21和出水管22平行设置,这样水管接头装接方向也是平行的,接管时二者之间不会相互干涉,而且任一管的拔除也不会误致其他管被拔掉。入水管21、出水管22、第一盖体12为一体注塑成型件。
如图4和图5所示,第一盖体12上设有内伸管23,内伸管23与入口14相连且位于溶气腔10内,内伸管23的自由端设有内喷口25。内伸管23的设置将内喷口25伸到溶气腔10的内部且远离第一盖体12的端部,使溶气腔10四周内壁均能够与内喷口25间隔一定距离,从而充分利用溶气腔10的内壁来使入水激出水花。
内伸管23的延伸方向与内喷口25的轴线相垂直。由此,水流经过内伸管23内的流道从内喷口25排出时,流动方向发生急转,在溶气腔10内溅起大量水花,利于空气的溶解。
更具体地,内伸管23水平设置,内喷口25的朝向使得水流的流向改为向下设置。当溶 气腔10内蓄积一定水量时,沿水平方向流入的入水急转向下喷射,入水水流刺入液面,不仅使水流与水面相撞激起的水花剧烈,而且可以将空气带入液下,从而加快了空气溶解速度。当然,在本发明的其他实施例中,内喷口25的喷射方向也可以是倾斜的,即水流的入射方向可以与竖直方向呈一定夹角,这样入射水流冲击面积非常大。
内伸管23与入水管21沿同一直线设置,工作时,水流通过入水管21进入内伸管23,然后从内喷口25喷入溶气腔10内。
如图1、2所示,第二盖体13上设有补气管24,补气管24与补气口16相连。具体地,补气管24沿加液盒体11的长度方向设置,可选地,补气管24与入水管21、出水管22均平行。
本发明实施例中,空化件4可以采用现有技术中已经公知的空化装置的结构,例如采用超声波发生器等。
在一些可选实施例中,如图5所示,空化件4内设有至少一个文丘里通道41。每个文丘里通道41在水流流动方向上,过流面积先逐渐减小然后逐渐增大。文丘里通道41的截面形状这里不作限定,文丘里通道41的截面可选圆形以便于加工,但是在其他实施例中文丘里通道41的截面也可以是椭圆等形状。
溶气腔10内大量空气溶质水流入空化件4后,不能通过文丘里通道41平缓流出,文丘里通道41两端形成极大压差,有助于完成空化作用。具体地,空化作用的相关原理为:
文丘里通道41进端处的平均速度、平均压力和截面积分别为V1、P1、S1,文丘里通道41截面最小处的平均速度、平均压力和截面积分别为V2,P2,S2,水的密度为ρ,在工作状态下,假设以自来水为工作介质,满足关系式:S1*V1=S2*V2。
利用伯努利定律和连续性方程可以得到关系式:V1 2/2+P1/ρ=V2 2/2+P2/ρ。
在此过程中通过控制S1与S2的变化,使得在文丘里通道41中,截面最小处流速增大,截面最小处压力变小,因此溶解在水中的空气以微气泡的形式释放出来。
在一些实施例中,空化件4通过螺纹连接在出口15处,可选地,空化件4上设有外螺纹,出水管22上设有内螺纹,空化件4可旋接连接在出水管22上。具体地,空化件4与溶气罐1之间设有密封垫61,从而保证空化件4与溶气罐1连接处的密封性。
具体地,入口14的最小内径为空化件4的最小内径的2-5倍。这样可以在微气泡发生器100工作过程中,大部分时间入水流速大于出水流速,使溶气腔10内空气空间挤压而压力逐渐上升。当入口14的截面为圆形时,入口14截面最小处直径为其最小内径。当入口14截面为非圆形时,入口14的截面面积最小处的有效圆直径,为其最小内径。
更具体地,当空化件4内仅一个文丘里通道41时,空化件4的最小内径指的是该文丘 里通道41的最小截面处直径。当空化件4内设有多个文丘里通道41时,其最小内径为截面面积最小处的有效圆直径。空化件4内截面面积最小处的有效圆,其面积等于所有文丘里通道41的最小截面面积之和。
在一些实施例中,如图1和图2所示,微气泡发生器100还包括设在补气口16处的单向阀5,这样使外部空气单向压入溶气腔10内,而且溶气腔10内空气和水都不能通过补气口16处排出。
具体地,单向阀5为双重阀芯结构,这样可达到双重密封防漏保障。而且由于双重阀芯的结构使空气吹入溶气腔10时,需要依次经过两重阀芯50,充入的空气在每打开一次阀芯50缓冲一次。而且腔内的水或者空气向阀芯50施压时,也有两重阀芯50分担压力,可保证腔内压力为1.2MPa情况下,腔体内的水不会压坏单向阀5,使单向阀5从补气口16往溶气罐1内进气通畅。
更具体地,如图7所示,单向阀5包括:第一阀体51、第二阀体52、第三阀体53、两个阀芯50和两个弹性件58,第一阀体51位于溶气腔10内且装设在第二盖体13上,第一阀体51对应补气口16设置。第二阀体52套装在第一阀体51上以与第二盖体13、第一阀体51之间限定出第一活动腔56,第二阀体52上设有中间口54,第三阀体53装设在第二阀体52上以与第二阀体52之间限定出第二活动腔57,第三阀体53上设有内口55,内口55连通溶气腔10。两个阀芯50分别套装在两个阀芯50上活动腔活动腔,两个弹性件58分别设在第一活动腔56和第二活动腔57内,第一活动腔56内的弹性件58用于将阀芯50朝向封堵补气口16的方向驱动,第二活动腔57内的弹性件58用于将阀芯50朝向封堵中间口54的方向驱动。这样的单向阀5装配非常容易,而且方便检修。
两个阀芯50沿补气口16的进气方向排布,从而使进气时对两重阀芯50的作用方向一致。
第一阀体51为圆管形,第一阀体51一体形成在第二盖体13上,从而便于密封加工。可选地,第二阀体52形成为具有中间隔板的管状,管状一端套接在第一阀体51上,管状另一端套接在第三阀体53上。
每个阀芯50均包括阀盖501和连接在阀盖501上的阀柱502,弹性件58为弹簧,弹性件58外套在阀柱502上且抵接在阀盖501上。采用阀盖501加阀柱502的结构,这样阀芯50用于封闭相应口的端面面积大,密封作用强,而阀芯50在非密封配合处截面小,方便套装定位。弹簧外套阀柱502,可以利用阀柱502起到导向作用,使弹性件58的收缩方向受限制,这样阀芯50及弹性件58均不易卡死。
具体地,在第一活动腔56内,阀盖501的端面及第二盖体13上与阀盖501的对应位置 处分别形成有在远离彼此的方向上设置的弧形面。在第二活动腔57内,阀盖501的端面及第二阀体52上与阀盖501的对应位置处分别形成有在远离彼此的方向上设置的弧形面。如此设置,在外部空气吹入单向阀5时,空气吹到阀盖501的端面上,阀盖501端面的弧形设置可使空气均匀导向阀盖501的四周,同样地,设置有补气口16和中间口54的表面均是弧形面,也能将空气均匀导向四周。这样可使吹入的空气均布在整个阀盖501端面上,从而使阀盖501打开时平稳,避免阀盖501受力不均歪斜导致卡死的现象,同时在结束吹气后,阀盖501回位时,弧形设置使阀盖501端面可起到一定的缓冲作用。
在图1-图7的具体示例中,水流从第一盖体12上的入水管21接入,入水管21内的水流从内伸管23流到内喷口25,然后从内喷口25处向下喷入溶气腔10内。喷入溶气腔10内的水在溶解了空气后,再从出水管22处连接的空化件4排出。设计时保证在腔内水压未达到阈值时,单位时间内的进水量高于出水量,因此在密封的溶气腔10内形成高压,空气在压力的作用下溶于水中,空化件4是利用文丘里效应制作的空化装置,当含有高浓度空气溶质的水进入空化件4后,经空化件4的空化效应制成带有微气泡的排出。
持续工作一段时间过后,溶气腔10内存的水较多,占用的空间较大,而且在排水的同时,溶气腔10内的微气泡也在破裂消失。此时,需要控制入水管21处的进水暂停,空气泵通过第二盖体13上的补气管24往溶气腔10内吹气,将溶气腔10内存储的这部分微气泡含量低的水排出,然后新的周期开始,水再次通过入水管21进入溶气腔10内。
根据本发明实施例的洗涤装置,包括根据本发明上述实施例的微气泡发生器100,微气泡发生器100的结构在此不再赘述。
根据本发明实施例的洗涤装置,通过微气泡发生器100的巧妙设计,利用溶气罐1出入水流形成流速差,溶气罐11内逐渐升压形成高压腔,从而能提高溶气量。空化件4能使高浓度空气溶液快速制成微气泡,结构简单,安装容易。本发明基于文丘里效应和空化效应提出一种微气泡发生器100,该装置结构简单,可在短时间内产生较多气泡,制泡效果好,安装方便。与洗衣机结合时,借助微小气泡的爆炸产生的冲击力,可加速衣物纤维间污渍的溶解,提高洗涤效率。将这样的微气泡水作为洗涤水可以减少洗衣粉或者洗涤剂的用量,节约水电资源,减少衣物上残留的洗衣粉或者洗涤剂。
根据本发明实施例的洗涤装置的其他构成例如电机和减速器、排水泵等结构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。

尽管已经示出和描述了本发明的实施例,本领域的普通技术人员可以理解:在不脱离本发明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,本发明的范围由权利要求及其等同物限定。
