在本发明中,所述喷淋臂包括本体及设于该本体上方的顶板,所述本体具有沿本体长度方向延伸的流道,所述顶板与本体顶壁共同围合出所述的集气腔,所述本体的顶壁上开有与流道相连通且位于集气腔中的第二喷孔,所述第一喷孔开设于顶板上且与第二喷孔相对应,所述第一喷孔与第二喷孔之间具有间隙。采用上述结构,根据文丘里效应,在水流经过第二喷孔、第一喷孔射出的过程中,可通过二者之间的间隙将集气腔中的空气吸入水柱中,从而使射流中夹带有气泡,该气泡在碗碟或果蔬表面破碎可提高污物剥离力,提高清洗效果;并且,通过自吸气的方式将气体加入射流中,无需设置气泵等,可大大降低生产成本。In the present invention, the spray arm includes a main body and a top plate disposed above the main body, the main body has a flow channel extending along the length of the main body, and the top plate and the top wall of the main body together enclose the gas collection The top wall of the main body is provided with a second nozzle hole that communicates with the flow channel and is located in the gas collection cavity, the first nozzle hole is opened on the top plate and corresponds to the second nozzle hole, and the first nozzle hole is opened on the top plate and corresponds to the second nozzle hole. There is a gap between the first spray hole and the second spray hole. With the above structure, according to the Venturi effect, in the process of the water flow passing through the second nozzle hole and the first nozzle hole, the air in the air collecting cavity can be sucked into the water column through the gap between the two, so that the entrainment in the jet flow can be achieved.

The above-mentioned first nozzle and second nozzle are beneficial to guide the water flow, so as to form a water column with a large spray force.
优选地,所述第一喷嘴下端与第二喷嘴上端之间的间隙宽度为2~5mm。此间隙决定了射流空化能力的强弱,即吸入空气量的多少,经验证,采用上述长度参数,可获得较高的射流空化效果。Preferably, the width of the gap between the lower end of the first nozzle and the upper end of the second nozzle is 2-5 mm. This gap determines the strength of the jet cavitation capability, that is, the amount of air inhaled.

优选地,所述第二喷嘴具有沿水流方向依次衔接的锥形段及第一直线段,所述锥形段的内径沿水流方向逐渐变小。所述第一喷嘴的内径在轴向上保持一致且大于第二喷嘴第一直线段的内径。上述锥形段有利于减少流体自流道进入第二喷嘴中的能量损失;根据文丘里效应,受限流体在通过缩小的过流断面时,流体会出现流速增大的现象,而由伯努利定律知流速的增大伴随流体压力的降低,从而在高速流动的流体附近会产生低压,进而产生吸附作用,本发明的第一直线段意在实现截面变小流速增大的作用,以使集气腔中的气体通过间隙被吸入水流中。Preferably, the second nozzle has a conical section and a first straight section connected in sequence along the water flow direction, and the inner diameter of the conical section gradually decreases along the water flow direction. The inner diameter of the first nozzle is consistent in the axial direction and is larger than the inner diameter of the first straight section of the second nozzle. The above-mentioned tapered section is beneficial to reduce the energy loss of the fluid entering the second nozzle from the flow channel; according to the Venturi effect, when the confined fluid passes through the reduced flow cross-section, the fluid will have an increase in the flow velocity, and the phenomenon is caused by Bernoulli. It is known by law that the increase of the flow velocity is accompanied by the decrease of the fluid pressure, so that a low pressure will be generated near the fluid flowing at a high speed, and then the adsorption effect will be generated. The gas in the air cavity is drawn into the water flow through the gap.
优选地,所述第一喷嘴的轴向长度为5~7mm。本发明的第一喷嘴主要用于进行气液混合,第一喷嘴的尺寸决定气液混合后状态的稳定性,第一喷嘴的长度过长会造成射流能量损失、过小会造成气液混合状态不稳定,经验证,采用上述长度参数,可获得高速且气液混合后状态稳定的流体。Preferably, the axial length of the first nozzle is 5-7 mm. The first nozzle of the present invention is mainly used for gas-liquid mixing. The size of the first nozzle determines the stability of the state after gas-liquid mixing. If the length of the first nozzle is too long, it will cause the loss of jet energy, and if the length of the first nozzle is too small, it will cause the gas-liquid mixing state. It is not stable. It has been verified that the above-mentioned length parameters can be used to obtain high-speed and stable fluids after gas-liquid mixing.

具体实施方式Detailed ways
以下结合附图实施例对本发明作进一步详细描述。The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.
如图1~8所示,本实施例的清洗机包括箱体1、喷淋臂2及泵水机构3,喷淋臂2设于箱体1中并靠近底部布置,泵水机构3设于箱体1底部且用于将箱体1底部的水泵至喷淋臂2中。As shown in Figures 1 to 8, the cleaning machine of this embodiment includes a box body 1, a
如图3所示,箱体1底部设置有下凹的沥水区域11,该沥水区域11的顶部覆盖有沥水板12,沥水区域11中设置有穿过沥水板11布置的导流座13,喷淋臂2能转动地支承在该导流座13的顶部,泵水机构3用于将沥水区域11的水经导流座13泵至沥水板12上方的喷淋臂2中。As shown in FIG. 3 , the bottom of the box body 1 is provided with a
如图5、6、8所示,喷淋臂2具有沿长度方向延伸的流道21,喷淋臂2的中央部位具有与流道21相连通的大致呈圆盘状的集水腔22,喷淋臂2的底壁上开有与集水腔22相连通的进水口23、顶壁上开有喷水孔。As shown in FIGS. 5 , 6 and 8 , the
泵水机构3包括电机31及叶轮32,叶轮32的上部能转动地设于集水腔22中,叶轮32的下部位于进水口23下方,叶轮32的上部为离心叶轮、用于将集水腔22中的水分散至流道21中,叶轮32的下部为轴流叶轮、用于将沥水区域11的水向上汲取。电机31设于箱体1的外底壁上,电机31的动力输出轴311穿过箱体1底壁向上再穿过进水口23伸入喷淋臂2中,叶轮32套置在动力输出轴311的外周并随之转动。The
如图1、3所示,本实施例设置了能使清洗机具备蒸汽预洗功能并在洗涤完毕后对碗碟进行高温消毒的蒸汽发生器4。动力输出轴311内部中空形成导气通道310,蒸汽发生器4的蒸汽输出端与导气通道310相连通。As shown in FIGS. 1 and 3 , in this embodiment, a steam generator 4 is provided that enables the washing machine to have a steam pre-wash function and to perform high-temperature sterilization on the dishes after washing. The inside of the
箱体1上部的侧壁上开有水流输入口14,箱体1底部的拐角处设置有与水源相连通的进水阀5,该进水阀5的第一输出口51通过管道与水流输入口14相连接,该进水阀5的第二输出口52通过管道与蒸汽发生器4的输入端相连接,蒸汽发生器4的蒸汽输出端通过导管41与动力输出轴311的下端口相连接。蒸汽发生器4中设置有能控制用于产生蒸汽的水流量大小的限流机构,以便于控制蒸汽量的大小。A water
箱体1侧壁上开设有透气口15,箱体1外侧设置有与该透气口15相连接并用于向箱体1中输入干燥气体和/或将箱体1中的湿气排出的换气机构6。换气机构6中可以设置有用于对空气进行输入箱体1中的空气进行加热的加热件。该结构便于在水洗完毕后配合蒸汽实现碗碟的消毒及烘干。A
在本实施例中,如图6所示,喷淋臂2的顶壁上开有第一喷孔24,沿流体流通方向,喷淋臂2具有位于第一喷孔24上游的用于向第一喷孔24方向输送气体的集气腔25,动力输出轴311的上端口与该集气腔25相连通。通过上述集气腔25不仅便于使蒸汽均匀分散至各喷孔处,而且上述集气腔25也便于向喷射水流中加气,从而将蒸汽输送与空化加气结构集成在一起,简化整机结构,降低成本。In this embodiment, as shown in FIG. 6 , the top wall of the
具体的,喷淋臂2包括本体2a及设于该本体2a上方的顶板2b,流道21位于本体2a中且沿本体2a长度方向延伸,顶板2b与本体2a顶壁共同围合出集气腔25。本体2a的顶壁上开有与流道21相连通且位于集气腔25中的第二喷孔26,第一喷孔24开设于顶板2b上且与第二喷孔26相对应,如图7所示,第一喷孔24与第二喷孔26之间具有间隙200。根据文丘里效应,在水流经过第二喷孔26、第一喷孔24射出的过程中,可通过二者之间的间隙200将集气腔25中的空气吸入水柱中,从而使射流中夹带有气泡,该气泡在碗碟或果蔬表面破碎可提高污物剥离力,提高清洗效果;并且,通过自吸气的方式将气体加入射流中,无需设置气泵等,可大大降低生产成本。Specifically, the
如图1、4所示,本实施例的动力输出轴311上还连接有仅允许外界空气进入导气通道310中的单向阀7。设置该单向阀7,在蒸汽发生器4向导气通道310中输入蒸汽时,可避免蒸汽外溢,在蒸汽发生器4停止向导气通道310输送蒸汽的水洗过程中,便于通过该单向阀7、导气通道310向喷射水流中加入空气,从而利用空化作用提高清洗效果。As shown in FIGS. 1 and 4 , the
在本实施例中,如图4所示,喷淋臂2上设置有能在动力输出轴311正转状态下使喷淋臂2与动力输出轴311相脱离、在动力输出轴311反转状态下使喷淋臂2随动力输出轴311转动的传动结构8。该结构可使喷淋臂2在蒸汽输送阶段、在不利用叶轮转动产生的水流粘滞力的情况下进行转动,从而对喷出的蒸汽进行搅动,提高蒸汽扩散效率及均匀性。In the present embodiment, as shown in FIG. 4 , the
喷淋臂2上开有供动力输出轴311穿过并伸入集气腔25中的安装孔27,该安装孔27开设于集水腔22的顶壁上,安装孔27的内壁与动力输出轴311的外壁之间设置有单向轴承,该单向轴承构成上述传动结构8。单向轴承结构简单、便于装配,装配后占用空间小、使用稳定性好,便于在蒸汽输送状态下允许喷淋臂转动而提高蒸汽扩散效率及均匀性、在水洗阶段避免其与喷淋臂之间的旋转产生干涉。The
如图4所示,本实施例的叶轮32顶部具有端盖321,该端盖321自边缘向中央部位逐渐向下凹陷形成凹陷区322,该凹陷区322对应安装孔27布置,集水腔25的顶壁上下沉式设置有围绕安装孔27布置且部分伸入凹陷区322中的安装仓28,单向轴承设于该安装仓28中。采用上述叶轮32结构,叶轮32旋转时在集水腔25中产生负压有利于提高水流汲取效果,但是,在清洗过程中,端盖321的凹陷区322与集水腔25顶壁之间容易集聚大的气泡,严重影响泵的实际扬程;使安装仓28下沉至凹陷区322,不仅为单向轴承提供了安装空间,而且可将此处集聚的气泡向边缘挤压并进一步通过流道21排出,有利于避免气泡在此处集聚、扩大,降低对泵水机构扬程的影响。As shown in FIG. 4 , the top of the
在本实施例中,如图7所示,顶板2b上设置有沿第一喷孔24轴向延伸的第一喷嘴241,相应的,本体2a顶壁上设置有自第二喷孔26边缘向上延伸的第二喷嘴261。上述第一喷嘴241、第二喷嘴261有利于对水流进行引导,从而形成喷射力较大的水柱。In this embodiment, as shown in FIG. 7 , the
具体的,第一喷嘴241下端与第二喷嘴261上端之间的间隙200宽度d2为2~5mm。此间隙200决定了射流空化能力的强弱,即吸入空气量的多少,经验证,采用上述长度参数,可获得较高的射流空化效果。Specifically, the width d2 of the
如图7所示,第二喷嘴261具有沿水流方向依次衔接的锥形段2611及第一直线段2612,锥形段2611的内径沿水流方向逐渐变小。第一喷嘴241的内径在轴向上保持一致且大于第二喷嘴261第一直线段2612的内径。上述锥形段2611有利于减少流体自流道21进入第二喷嘴261中的能量损失;根据文丘里效应,受限流体在通过缩小的过流断面时,流体会出现流速增大的现象,而由伯努利定律知流速的增大伴随流体压力的降低,从而在高速流动的流体附近会产生低压,进而产生吸附作用,本实施例的第一直线段2612意在实现截面变小流速增大的作用,以使集气腔25中的气体通过间隙200被吸入水流中。As shown in FIG. 7 , the
上述第一喷嘴241的轴向长度d1为5~7mm。本实施例的第一喷嘴241主要用于进行气液混合,第一喷嘴241的尺寸决定气液混合后状态的稳定性,第一喷嘴241的长度过长会造成射流能量损失、过小会造成气液混合状态不稳定,经验证,采用上述长度参数,可获得高速且气液混合后状态稳定的流体。The axial length d1 of the
