Description
本发明属于洗涤设备领域,具体地说,涉及一种洗涤设备自动投液装置及洗涤设备。
传统的洗衣机在洗涤过程中使用的洗涤剂与洗衣机是分开放置的,在洗衣机上没有设置洗涤剂的添加装置,洗涤剂不能自动添加,不能实现洗衣机的洗衣过程全自动。随着洗衣机自动化的提高,大多洗衣机设计成盛放洗涤剂或/和柔软剂的洗涤剂盒与进水管路相通,通过进水将洗涤剂盒内的洗涤剂或/和柔软剂冲入洗涤桶中,但是该结构必须每次洗衣前先将洗涤剂或/和柔软剂放入洗涤剂盒中,同样没有实现洗衣过程全自动。
目前已有关于洗涤剂自动投放装置的专利申请:

有鉴于此,特提出本发明。
发明内容
本发明的目的在于提供一种洗涤设备自动投液装置,以实现快速自动添加洗涤剂液体,减少投液装置的配置,简化投液装置的结构的目的。
本发明的另一目的在于提供一种洗涤设备,以实现控制洗涤剂的自动精确添加的目的。
为解决上述技术问题,本发明采用技术方案的基本构思是:
一种洗涤设备自动投液装置,包括驱动装置5和吸液装置6,吸液装置6包括容纳液体的吸液腔602,还包括:膜片1,膜片1构成吸液腔602的部分侧壁,膜片1具有弹力并且能够通过弹性变形改变吸液腔602内部与外部之间的气压差,使所述吸液装置6进液、排液;动子4,用于对膜片1施力使膜片1产生弹性变形,动子4与膜片1不连接。
该技术方案中,动子4与膜片1是分离的两个部件,驱动装置5提供驱动力使动子4运动起来。运动的动子4具有动能,撞击膜片1时能够使膜片1发生弹性变形。随着膜片1的变形量不断变大,动子4的动能不断减小直至为零,动子4速度为零时膜片1的变形量达到最大。其中膜片1是构成吸液腔602的一个侧壁,膜片1的弹性变形会改变吸液腔602内的气压,使吸液腔602内的气压与外界气压的大小关系发生变化,产生压力差。膜片1被动子4撞击后向吸液腔602的内部产生变形,使吸液腔602内的体积变小,腔内压力变大,向外部排出液体。膜片1具有弹性,变形后的膜片1会产生弹性回复力,在弹性回复力的作用下,膜片1的变形部位会向原始位置回归并超过原始位置继续向原变形方向的反方向运动,即向
吸液腔602的外部方向变形,从而不断地在原始位置两侧往复运动,也就是说膜片1会处于振动的状态。
在膜片1的变形部位向原始位置回归并向吸液腔602的外部方向变形的过程中,吸液腔602内的体积变大,腔内压力变小,吸液装置6吸入液体。
进一步地,所述动子4初始位置远离所述膜片1,受所述驱动装置5驱动向所述膜片1运动,撞击所述膜片1使其发生弹性变形,所述膜片1发生弹性变形后具有回弹力可将所述动子4弹回初始位置。
该方案中,动子4初始位置距离膜片1有一定距离,动子4在驱动力的牵引下逐渐加速,在该距离内可以积蓄一定量的动能,使膜片1被撞击后可以获得更大的变形量。变形后的膜片1会产生弹性回复力,在弹性回复力的作用下,动子4会被送回初始位置,等待进行下一次的撞击动作。
进一步地,还包括设置在动子4上远离膜片1侧的弹性元件3,所述动子4在初始位置时与所述膜片1接触,所述动子4被所述驱动装置5驱动远离所述膜片1并压缩弹性元件3,所述弹性元件3的弹性势能将所述动子4通过回弹力撞击所述膜片1。
进一步地,所述弹性元件3被压缩直至所述动子4速度降为零时,所述弹性元件3反弹,所述动子4受所述弹性元件3驱动加速向所述膜片1运动,并撞击所述膜片1使其发生弹性变形。
进一步地,所述的弹性元件3一端被固定在驱动装置5上,另一端与所述动子4连接。进一步地,所述动子在所述驱动装置5的驱动力、膜片1和/或弹性元件3的回弹力的作用下连续往复运动,使膜片1产生弹性变形。
进一步地,所述驱动装置5包括可产生磁场的线圈501,所述动子4的形心总是偏离线圈501的形心设置,所述线圈501的磁场对所述动子4产生磁力,磁力的方向朝着线圈501的形心并驱动所述动子4运动。
一个单向的磁力以一定的频率出现和消失,或者增强和减弱,在动子4受到单向磁力驱动时不断压缩弹性元件3,将其产生的动能转化为弹性元件3的弹性势能,在单向磁力消失时被压缩的弹性元件3挤压动子4,将弹性元件3的弹性势能释放到动子4上,转化为动子4的动能,完成撞击膜片1的动作。将动子的形心与线圈的形心偏离设置,可以保证自动投液装置启动后动子4总是能够受到单向的磁力作用,进而可以引起动子4在平衡位置的左右作往复运动,避免出现线圈501通电产生磁场后,由于动子4的形心与线圈501的形心重合,动子4不受磁力的作用,无法产生运动的情况。保证了动子4在受到单向的作用力时,能够不断地在受力平衡点的左右往复运动,不断地撞击膜片1。
进一步地,所述线圈501中通交流电,产生的磁场是变化的磁场,动子4所受磁力的大小跟随磁场强度变化。
该技术方案中,在线圈501中通入交流电,线圈501的绕制匝数固定不变,由于通入交流电的正负极不断交替并且电流强度不断变化,使线圈501产生的磁场强度随着电流强度的改变而相应变化。此时,磁场具有与交变电流相关的频率,动子4在该磁场中受到的磁力也具有一定的频率。磁力是激发动子4振动的激振力。动子4在激振力的作用下会不断反复运动,撞击膜片1。
磁力以一定的频率增强和减弱,在动子4受到较强磁力驱动时不断压缩弹性元件3,将其产生的动能转化为弹性元件3的弹性势能,在磁力减弱时被压缩的弹性元件3挤压动子4,将弹性元件3的弹性势能释放到动子4上,转化为动子4的动能,完成撞击膜片1的动作。
进一步地,所述驱动装置5包括壳体2和套筒202,所述驱动装置5设置在壳体2的内部,套筒202的轴向中心线与所述线圈501的轴向中心线重合设置,所述动子4的外形与套筒202空腔的形状相同且所述动子4可在套筒202中滑动。
该技术方案中,通过壳体2将驱动装置5和套筒202固定在一起,并使线圈501套在套筒202的外侧,动子4在套筒腔203中运动,有利于保持动子4反复运动时的位置和姿态,并且能够使动子4沿着线圈501产生的磁场方向运动,有利于增大动子4撞击膜片1的力量。同时,使线圈501的中心轴线与套筒腔203的中心轴线重合,有利于动子4在线圈501产生的磁场中受到的驱动力最大。将驱动装置5和套筒202通过壳体2固定,保证了动子4运动的稳定性,防止动子4的往复运动引起自动投液装置的振动,进而导致损坏,有利于使投液装置长期使用。
本发明还提供一种具有上述自动投液装置的洗涤设备。
采用上述技术方案后,本发明与现有技术相比具有以下有益效果。
1、该洗涤设备自动投液装置能够驱动动子以一定的频率反复地撞击膜片,使膜片产生振动并引起吸液腔内部和外部的气压大小关系不断变化,进而通过改变吸液腔内外的气压差达到投放液体的目的,当吸液腔内压力变小时,吸入液体,当吸液腔内压力变大时,排出液体,该投液装置仅包括动子和吸液腔,大大减少了投液装置的结构件,通过加快动子的撞击频率可以加快投液速度,能够调整添加洗涤剂液体的速度。
2、通过磁力驱动的自动投液装置可以保证动子总是能够受到单向的磁力作用,进而可以引起动子在平衡位置的左右作往复运动,避免出现线圈通电产生磁场后,由于动子的形心与线圈的形心重合,动子不受磁力的作用,无法产生运动的情况。
3、弹性元件和动子组成的一个系统,具有固定的振动频率,该振动频率与弹性元件的弹性系数和动子的质量相关,当激振力的频率与被激振系统的固有频率一致或者呈整倍数关系时,会发生共振,可以通过调节交流电的频率来使磁力的频率与动子和弹性元件组成的系统的固有频率呈整倍数关系,进而增大膜片被撞击时的形变幅度,增加膜片单次振动所能吸取的液体量和投放的液体量,增强投液效果。
本发明要解决的技术问题在于克服现有投液装置自动化程度较低和结构可靠性较差技术的不足,提供一种用于洗涤设备的自动投液装置。
为解决上述技术问题,本发明采用技术方案的基本构思是。提供一种用于洗涤设备的自动投液装置,包括壳体和吸液装置,所述壳体内设置有驱动装置和套筒,所述驱动装置包括线圈,线圈绕设于所述套筒的外侧,所述壳体的一端与所述吸液装置连接,还包括活动组件。
所述活动组件包括动子和膜片,所述膜片设置在所述吸液装置内并部分与吸液装置连接,所述动子的一个端部与所述膜片连接,所述驱动装置给予动子提供磁驱力,驱动所述动子在套筒内进行周期性的往复运动,致使所述膜片与动子以相同的频率振荡。采用上述方案,将用于洗涤设备的自动投液装置分成了壳体、吸液装置和活动组件三部分,限定了三部分的包含及连接位置关系,通过活动组件周期性的往复运动改变吸液装置的容积,完成吸液和排液进程,这种方案能使用于洗涤设备的自动投液装置的结构简单化,在保证其使用寿命的前提下,更加地便于加工制造。
进一步地,所述膜片的周边边缘与吸液装置的腔室壁固定连接;初始位置状态下,所述动子的形心偏离线圈的形心设置,所述膜片无形变;线圈通入交流电后,所述动子受到的磁驱力总是指向线圈的形心方向但磁驱力的大小周期性的变化;所述动子在磁驱力的作用下通过拉动和/或推动使所述膜片发生形变进行往复振荡,使洗涤液吸入和排出吸液装置。采用上述方案,膜片的周边边缘固定在吸液腔室的内壁上,悬空的膜片形成了膜片的可形变部位,动子拉动、推动膜片整体运动的同时,膜片自身由于受力也发生前后振荡,这种震荡能将洗涤液更多的排出吸液腔室,进而提升了用于洗涤设备的自动投液装置的投液效率。
进一步地,所述动子与所述膜片两者通过一体化成型、不可拆连接或可拆卸连接的方式连接一体形成活动组件,所述动子与膜片连接的一端部分外露于套筒。所述套筒远离膜片方向的一端设置有弹性元件。所述动子拉动和/或推动使膜片发生形变,膜片变形产生对动子作用的膜片复位力和/或弹性元件变形产生对动子作用的弹簧弹力。所述膜片复位力阻碍或协助
磁驱力使动子运动,或者,所述弹簧弹力阻碍或协助磁驱力使动子运动。采用上述方案,活动组件具有能适应多种不同条件状况下的形成方案,扩宽了用于洗涤设备的自动投液装置的可应用范围;同时动子与膜片连接的一端部分外露于套筒,即膜片距离套筒的开放端具有一定的距离,以此保证膜片套筒方向移动时具有足够的缓冲空间。
进一步地,所述的不可拆连接方式包括。所述动子的一端部与所述膜片的中心部位粘接连接,形成活动组件。采用上述方案,动子与膜片粘接固定,简单的连接能极大地降低制造的难度和生产制的成本,契合实际的市场需求。
进一步地,所述的一体化成型连接方式包括。所述动子朝向膜片方向的端部设置有伞状或蘑菇形状的嵌入块。所述膜片内设有与嵌入块配合的安装固定件;将动子与所述安装固定件配合连接形成的整体放置到模具中,在安装固定件的四周通过一体化注塑成型形成与动子连接的膜片。采用上述方案,以动子与安装固定件配合连接形成的整体作为膜片中心的支撑部件,模具内注塑形成与整体一体化的膜片结构,这种方案使动子与膜片的连接具有更高的可靠性,能使活动组件在长时间的使用后依然保持初始的位置关系,极大地提升了用于洗涤设备的自动投液装置的使用寿命,契合用户的实际使用需求。所述的可拆卸连接方式包括。所述动子朝向膜片方向的端部设置有伞状或蘑菇形状的嵌入块。所述膜片的中心部位具有一定的厚度;所述膜片内设置有与嵌入块卡接配合的嵌入部。所述嵌入块与嵌入部配合卡接,实现动子与膜片的连接。采用上述方案,动子端部的嵌入部与膜片内的嵌入部卡接连接,这种可拆卸连接使连接的结构更具有可靠性和实用性,在保证活动组件运动实现吸液和排液功能的前提下,极大地提升了用于洗涤设备的自动投液装置的使用寿命。
进一步地,所述动子还包括哑铃形状的传导部,所述传导部的一端连接运动部,另一端上设置有嵌入块,所述嵌入块与嵌入部配合卡接,实现动子与膜片的连接。采用上述方案,应用于前述的粘接连接、一体化注塑成型和嵌入配合卡接的结构形成了新的具体结构,传导部的设计,能通过减少运动部的体积来降低动子整体的体积及重量,降低生产的成本和降低驱动装置驱动的能量使用,而且传导部的应用能使活动组件收到的驱动力更加集中,能提升动子带动膜片的变形程度,使用于洗涤设备的自动投液装置的使用性能得到进一步地提升。
进一步地,从初始位置向朝向线圈形心位置移动时,磁驱力克服膜片复位力和/或弹簧弹力带动动子向朝向线圈形心位置方向先加速后减速移动,动子速度为零的位置为动子的第一极限位置。从第一极限位置向远离线圈形心位置移动时,膜片复位力和/或弹簧弹力克服磁驱力带动动子向远离线圈形心位置方向加速移动,移动过程中经过初始位置开始减速移动,此时磁驱力、膜片复位力和弹簧弹力均阻碍动子移动,动子速度为零的位置为动子的第二极限位置。从第二极限位置向初始位置移动时,膜片复位力方向朝向靠近线圈形心的方向,膜片复位力和/或弹簧弹力协助磁驱力带动动子向初始位置移动。采用上述方案,阶段性的状态分析,结合动子的受力对弹性元件和/或膜片的状态变化进行了描述,使得各阶段都能实现应有的功能,保证了功能的可靠性。
进一步地,所述第一极限位置与第二极限位置之间的距离,是动子的最大振幅。采用上述方案,谐振系统的整体具有的固定频率条件下,当交流电的转换频率使得谐振系统能以固定频率振动时,此时动子处于最佳状态,即此时动子以最大振幅来回振动。最大振幅的条件下,可以在单位时间内排出更多的洗涤液,提升了自动投液装置的工作效率。
进一步地,动子从初始状态位置向线圈形心位置移动时,所述膜片复位力和/或弹簧弹力阻碍磁驱力带动动子运动。动子从右极限位置向初始状态位置移动时,述膜片复位力和/或弹簧弹力协助磁驱力带动动子运动。采用上述方案,可以实现动子的快速制动和快速启动,使得动子的运动频率与交流电的转换频率之间在启动和运行一段时间后仍具有线性关系,保证了运动的统一和高效。
进一步地,所述膜片随动子的往复运动,动子从初始位置向第一极限位置和从初始位置向第二极限位置的过程中膜片变形的程度不同。采用上述方案,能在吸液时容积变化更大,
使更多的洗涤液吸入吸液腔,复位时还会相比原位多移动一段距离,保证了洗涤液的充分排出。
进一步地,所述膜片在动子从初始位置向第一极限位置过程中的变形程度大于在动子从初始位置向第二极限位置过程中的变形程度。采用上述方案,第二极限位置与初始位置的距离小于第一极限位置与初始位置的距离,保证弹性元件不会因为过度拉伸而导致功能失效,同时此方案还能使膜片周期性的处于变化的状态,防止膜片反复受到换向的作用力而导致的疲劳破坏,因此在一定程度上保证了自动投液装置的性能可靠性和使用寿命。
一种洗涤设备,采用上述的自动投液装置。
采用上述方案,自动投液装置提升了洗衣机的智能程度,节省了用户的洗衣投放洗涤液的不必要时间和精准的确定投放用量节省了洗涤剂不必要的浪费,更加契合用户的实际使用需求。

(3)本发明通过设置支撑弹簧、反弹弹簧,同时支撑弹簧套在反弹弹簧的外侧组成弹簧谐振系统,不仅可以给动子提供安装部位,保证其安装后水平处于套筒中,还由于反弹弹簧与述支撑弹簧的外径以及弹性系数不同,从而反弹弹簧与支撑弹簧之间可以配合组成的弹力范围更大,有效缩短单根弹簧需要提供一定恢复力的长度,可以更好的适应于动子移动后所需要提供的恢复力。

此外,本发明,动子的外周与套筒腔的内壁之间形成可供洗涤液通过的导流通道,一方面可使洗涤液沿套筒腔的周向移动,实现多次小剂量投放,投放更加精准;另一方面,导流通道使动子与套筒腔的内壁相隔离,避免动子动作时,与套筒腔的内壁发生摩擦,不会因为动子磨损影响进液、出液效果,有效提高了使用寿命,适于长时间使用。

为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对实施例中的技术方案进行清楚、完整地描述,以下实施例用于说明本发明,但不用来限制本发明的范围。
在本发明的描述中,需要说明的是,术语“左”、“右”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的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。

实施例一
如图1所示,本实施例中,自动投液装置包括动子4、驱动装置5和吸液装置6,动子4是独立的部件,与其他结构不连接。其中,吸液装置6包括容纳物体的吸液腔602,还包括膜片1,膜片1的边缘固定在吸液装置6上构成吸液腔602的部分侧壁。驱动装置5可以通过气动的方式驱动动子4,也可以通过电磁力的方式驱动动子4。例如,驱动装置5中设置有
气路,气路连通套筒202的底部,动子初始位置设在套筒202的底部,与膜片1间隔一段距离。向气路中通入压缩气体可以驱动动子4向膜片1运动,并撞击膜片1。
如图5所示,运动的动子4具有动能,撞击膜片1时能够使膜片1发生弹性变形。随着膜片1的变形量不断变大,动子4的动能不断减小直至为零,动子4速度为零时膜片1的变形量达到最大。其中膜片1是构成吸液腔602的一个侧壁,膜片1的弹性变形会改变吸液腔602内的气压,使吸液腔602内的气压与外界气压的大小关系发生变化,产生压力差。膜片1被动子4撞击后向吸液腔602的内部产生变形,使吸液腔602内的体积变小,腔内压力变大,向外部排出液体。膜片1具有弹性,变形后的膜片1会产生弹性回复力,在弹性回复力的作用下,膜片1的变形部位会向原始位置回归并超过原始位置继续向原变形方向的反方向运动,即向吸液腔602的外部方向变形,从而不断地在原始位置两侧往复运动,也就是说膜片1会处于振动的状态。在膜片1的变形部位向原始位置回归并向吸液腔602的外部方向变形的过程中,吸液腔602内的体积变大,腔内压力变小,吸液装置6吸入液体。
实施例二
作为本实施例的一种实施方式,如图1所示,本实施例中,驱动装置5包括套筒202,动子4的初始位置位于套筒202的左侧远离膜片1,受到驱动装置5驱动时,可向膜片1运动。动子4初始位置距离膜片1有一定距离,动子4在驱动力的牵引下逐渐加速,在该距离内可以积蓄一定量的动能,使膜片1被撞击后可以获得更大的变形量。动子4撞击膜片1后,膜片1会发生弹性变形并获得回弹力,膜片1可将动子4弹回初始位置。变形后的膜片1会产生弹性回复力,在弹性回复力的作用下,动子4会被弹回初始位置,然后在驱动装置5的驱动下再次进行撞击膜片1的动作。优选地,如图2所示,在套筒202的左侧和动子4上远离膜片1的一侧之间设置有弹性元件3,弹性元件3可将驱动装置5对动子4做的功转化为自身的弹性势能。
作为本实施例的另一种实施方式,动子4的初始位置位于套筒202的右侧,动子4与膜片1相接触。首先,动子4被驱动装置5驱动远离膜片1并压缩弹性元件3,弹性元件3被压缩后获得弹性势能和回弹力。然后,弹性元件3通过回弹力对动子4做功,使动子4向右加速运动并撞击膜片1。
本实施例中,通过改变动子4的初始位置与膜片1和距离,可以以膜片1的弹性回复力实现动子4的复位,利用驱动装置5的驱动力和膜片1的弹性,完成投液的动作。还可以利用弹性元件3的回弹力,对动子4进行驱动,进而使动子4撞击膜片1。
实施例三
作为本实施例的一种实施方式,如图2至4所示,本实施例中,在动子4的左侧设有弹性元件3,弹性元件3与套筒202的左侧底面连接或者与动子4的左侧端面连接。弹性元件3还可以自由搁置在套筒202的左侧底面与动子4的左侧端面之间。优选地,弹性元件3的左侧固定连接在套筒202上或者驱动装置5上,弹性元件3的右侧与动子4相连接。
如图3所示,弹性元件3包括支撑弹簧301,支撑弹簧301一端连接动子4、另一端连接套筒202,支撑弹簧301呈螺旋线状,在动子4接触膜片1时处于拉伸状态,提供脱离膜片1的拉力。支撑弹簧301始终连接动子4和套筒202,在动子4受到磁力作用冲向膜片1时,被逐渐拉伸变长,为动子4提供拉力,拉力在动子4撞击膜片1后,膜片1达到最大变形时弹簧的拉力最大。如此,支撑弹簧301为动子4提供一个返回的力,使动子4更快地离开膜片1。
作为本实施例的另一种实施方式,如图3所示,弹性元件3还包括反弹弹簧302,反弹弹簧302的一端连接动子4或套筒202,另一端悬空,反弹弹簧302呈螺旋线状,其长度小于套筒腔203与动子4长度的差值,动子4总是无法同时接触反弹弹簧302和膜片1,使动子4接触到膜片1时反弹弹簧302不处于压缩状态。反弹弹簧302有一端固定,该固定端可连接动子4的左侧或套筒202的底部,另一端悬空,反弹弹簧302在动子4运动过程中仅受压力,
可以快速地使动子4的速度降低,并使动子4反向加速冲向膜片1的方向。
实施例四
如图1-4所示,本实施例中,动子4由磁力驱动,自动投液装置包括驱动装置5和吸液装置6,驱动装置5包括可产生磁场的线圈501和套筒202。其中,线圈501为环状,由可导电的金属线环绕多圈制成;套筒202为狭长的柱形物体,套筒202沿轴线方向的长度大于线圈501沿轴线方向的长度,套筒202右端具有敞开口,左端不敞开,套筒202还包括套筒腔203,套筒腔203与套筒202的轴线共线,套筒腔203与套筒202右侧的敞开口贯通。套筒202设置在环状线圈501的中间,套筒202的中心轴线与线圈501的中心轴线平行或重合,线圈501靠近套筒202的右侧敞开口设置。吸液装置6包括容纳物体的吸液腔602和构成吸液腔602侧壁的膜片1。驱动装置5还包括动子4,动子4可活动地设置套筒202的套筒腔203中。动子4的初始位置靠近套筒的左侧,当线圈501中通入电流时,线圈501会产生磁场,对处于套筒202中的动子4形成磁力。
如图1至3所示,将动子4形心的初始位置设置在偏离线圈501形心的地方,例如,使动子4位于套筒202的左侧紧贴套筒202的底部,或者,使动子4位于套筒202的右侧紧贴膜片。这样可以使的动子4在系统启动后处于受力不平衡的状态,受到一个方向总是指向线圈501的形心的磁力,从而运动起来。线圈501的形心是线圈501通电后产生的磁场中磁通量最大的位置,在该磁场中任意位置的动子4受到的磁力的方向都指向该线圈501的形心。优选地,如图2和3所示,还可以在动子4与套筒202左侧的端部之间设置弹性元件3。
这样,动子4的形心向线圈501的形心接近的过程中会不断压缩弹性元件3,从而磁力对动子4做的功,会转化为弹性元件3的弹性势能。在磁力消失时,被压缩的弹性元件3挤压动子4,将弹性元件3的弹性势能释放到动子4上,动子4向右加速运动,弹性元件3的弹性势能转化为动子4的动能,进而动子4撞击膜片1。驱动装置5与吸液装置6连接在一起,使套筒202敞开口的右侧与构成吸液腔602侧壁的膜片1相贴合设置,保证了动子4运动撞击膜片1时,膜片1向吸液腔602内变形量更大。吸液装置6还包括吸液管603、排液管204和单向阀206,吸液管603和排液管204设置在吸液装置6最右侧的端面上,该端面与膜片相互平行。在吸液管603中设有单向阀206,仅允许液体从吸液腔602的外部进入吸液腔602的内部。在排液管204中设有单向阀206,仅允许液体从吸液腔602的内部流向吸液腔602的外部。动子4在套筒腔203中受磁力的驱动时,可以一定频率反复撞击膜片1,膜片1产生振动,进而使吸液腔602内气压与外界气压的大小关系不断变化,在吸液腔602内部压力小时吸入液体,压力大时排出液体。
实施例五
如图5所示,膜片1为平面状的薄片,膜片1包括固定端和变形端,固定端与吸液腔602的侧壁连接,变形端受到动子4撞击,吸收动子4的动能发生弹性变形。优选地,膜片1为圆形平面,圆形平面的边缘为固定端,固定端与吸液腔602的侧壁连接,圆形平面上的自由区域为变形端。线圈501的中心轴线垂直于膜片1的平面设置,动子4沿垂直于膜片1平面的方向往复运动。这样设置,动子4的运动方向垂直于所述膜片1的变形端。可以增加膜片1的形变幅度,进而增加每次膜片1振动时的吸液量。驱动装置5还包括壳体2,套筒202通过壳体2固定在线圈501的中心轴线位置,壳体2还包括翻边201,套筒202有开口的一端与翻边201连接在一起,套筒202的中心轴线与线圈501的中心轴线平行或者重合。套筒202是由薄壁形成的结构,其外部的形状为圆柱形,其内部还具有一个与外形同心的圆柱形空腔,即套筒腔203。动子4为实心的圆柱体,其截面圆的直径与套筒腔203的截面圆直径相等,动子4在套筒腔203中可自由地滑动,套筒202保证了动子4运动的稳定性。优选地,套筒202开口的中心正对膜片1的形心,此时,动子4撞击位置是膜片1变形端的形心。翻边201与膜片1的面相接触,翻边201与吸液装置6挤压膜片1的边缘,使膜片固定在套筒腔203和吸液腔602之间。优选地,翻边201与膜片1的面之间具有间隙,可供膜片振动时,向翻
边201方向发生变形。增大吸液腔602的体积,吸取更多的液体。同时,套筒腔203的轴向长度至少为动子4轴向长度的1.5倍,使得动子4在套筒腔203中运动时具有加速和减速的距离,可以积蓄动能,使撞击的动作力量更大。
实施例六
本实施例中,通过调整驱动力的频率与动子4往复运动的频率之间关系使得自动投液装置更高效率地投放洗涤液,驱动装置5通过磁力驱动动子4运动并撞击膜片1,使吸液装置6完成投放洗涤液的动作。
在该实施例中,可向线圈501中通入直流电,也可向线圈501中通入交流电,两种方式都可以驱动自动投液装置。
当线圈501中通直流电时,需要以一定频率控制电流的通断。
线圈501的绕制匝数和通入的电流强度固定不变的情况下,向线圈501中通入直流电,会产生强度和方向都不变的磁场。动子4在该磁场中受到的力一直保持不变,动子4逐渐压缩弹性元件3的过程中,受到的弹力不断变大直至与磁力平衡,动子4最终会静止在平衡位置。
通过控制磁力以一定的频率出现和消失,就能使动子4总是保持运动的状态,不断反复地撞击膜片1。
也就是说控制磁力在动子4的运动方向与磁力方向一致时出现,控制磁力在动子4的运动方向与磁力方向不一致时消失,保证磁力总是对动子4做正功。
当线圈中通交流电时,可以通过调节交流电的频率大小,改善自动投液装置的投液效果。
在向线圈501中通入交流电的情况下,由于交流电的正负极不断交替并且电流强度不断变化,线圈501产生的磁场方向也不断地交替,磁场强度随着电流强度的改变而相应变化。此时,磁场的强弱变化频率与交变电流的变化频率相同,动子4在该磁场中受到的磁力强弱变化也具有一定的频率,动子4总是处于运动状态。
通过控制直流电的通断频率和交流电的固有频率就可以控制自动投液装置投液进行投液,并改善投液的效率。而要改善和增强自动投液装置投液投液效果,可以通过调节交流电频率和直流电通断频率与动子振动频率之间的关系来实现。
其中,弹性元件3和动子4可以看成一个具有固定的振动频率的整体,即弹性振动系统。该整体的振动频率与弹性元件3的弹性系数和动子4的质量相关。通过调整动子4的质量和/或弹性元件3的弹性系数,改变该整体的固有振动频率。
磁力是激发动子4和弹性元件3组成的弹性系统振动的激振力。当激振力的频率与被激振系统的固有频率一致或者呈倍数关系时,会发生共振现象,从而增强自动投液装置的投液效果。
磁力可以通过调节电流而改变频率,比如调整直流电的通断频率,调整交流电的交变频率。因此,通过调节电流、调整动子4的质量、调整弹性元件3的弹性系数,可以改变驱动力的变化频率与动子4和弹性元件3组成的弹性振动系统频率之间的关系,使自动投液装置达到最佳的投液效果,通过调节交流电的频率来增大自动投液装置吸液腔602的体积变化量,增强投液效果。
实施例七
本实施例提供一种采用上述自动投液装置的洗涤设备。自动投液装置的吸液管603连接洗涤设备的洗涤剂储存盒,自动投液装置的排液管206连接洗涤设备的进水口,通入的水流与洗涤液混合后进入洗涤桶中。本实施例通过设置自动投液装置,实现了控制洗涤剂的自动精确添加,避免了洗涤剂过量添加损伤衣物,同时还简化了投液装置的结构。
实施例八
如图6至图14所示,本发明通过对用于洗涤设备的自动投液装置进行具体地结构设计,设置磁驱带动和弹性元件辅助移动的方式,提供了一种用于洗涤设备的自动投液装置及使用上述用于洗涤设备的自动投液装置的洗涤设备。
如图6至图8所示,本实施例提供的一种用于洗涤设备的自动投液装置,包括:壳体2和吸液装置6。壳体2内设置有驱动装置5和套筒202,壳体2的一端与吸液装置6连接。自动投液装置,还包括活动组件103,活动组件103包括动子4和膜片1。膜片1设置在吸液装置6内,动子4的一个端部与膜片1连接,驱动装置5驱动动子4在套筒202内进行周期性的往复运动,通过拉动和/或推动的方式使膜片1发生形变,膜片1的形变使洗涤液吸入和排出吸液装置6。具体地,膜片1与动子4以相同的频率振荡。所述的振荡指膜片1在动子4带动下进行左右方向的形变的同时膜片1自身有小范围内的谐振晃动。这种谐振晃动,使膜片1向吸液装置6的腔室和向套筒202方向具有不同的振幅,使部分洗涤液排出吸液装置6,一定程度上提升了用于洗涤设备的自动投液装置投放洗涤液的效率。具体地,动子4设置在套筒202内运动,动子4运动时与套筒202同轴。动子4限制于套筒202内运动且动子4运动时与套筒202同轴,既可以保证动子4运动时受到全部的驱动力尽可能多的有效化,提升了能量利用效率,也可以减少不必要的摩擦消耗,使用于洗涤设备的自动投液装置的工作效率更高。具体地,动子4为形状、体积相对固定不变化的金属结构件,本身不具有磁性且会在磁场的吸引下发生运动位移,但不会整体被磁化。具体地,动子4连接在膜片1的形心,膜片1的形心与其形变部位同心。
参见附图6,所述膜片1的周边边缘与吸液装置6的腔室壁固定连接。所述动子4通过拉动和/或推动使所述膜片1发生形变进行往复振荡,使洗涤液吸入和排出吸液装置6。
上述方案,膜片1的周边边缘固定在吸液腔室的内壁上,膜片的悬空部分形成了膜片的可形变部位,膜片1向吸液装置6的腔室的变形程度大于或等于向套筒202方向的变形程度。动子拉动、推动膜片整体运动的同时,膜片1自身由于受力也发生前后振荡,这种震荡能将洗涤液更多的排出吸液腔室,进而提升了用于洗涤设备的自动投液装置的投液效率。
在本实施例的另一个具体实施方案中,参见附图7至附图14,所述壳体2还包括与所述吸液装置6一端连接的翻边201,所述吸液装置6包括吸液腔602和与所述翻边201垂直连接的端盖601,所述端盖601上设有容纳所述膜片端部的凹槽,所述膜片1的端部固定于所述翻边201和所述端盖601凹槽之间,所述膜片1将所述套筒202一端覆盖密封并构成所述吸液腔602的一侧侧壁。
具体的,所述盖端601由吸液腔侧壁构成。进一步地,所述翻边201由套筒202具有角度的延伸一定长度形成,或者所述翻边201由壳体201的侧壁有角度的延伸一定长度形成。进一步地,膜片1的周边固定在翻边201和端盖601凹槽之间,膜片1将吸液装置6和壳体2连接起来。进一步地,膜片1的周边固定在翻边201和端盖601凹槽之间,膜片1在加持固定下,中间部位即是可形变区。
上述方案,膜片将吸液装置和壳体分割,膜片充当吸液装置内一侧壁的设计,能使用于洗涤设备的自动投液装置的结构构成简单化,便于加工制造。进一步地,动子4与膜片1两者通过一体化成型、不可拆连接或可拆卸连接的方式连接一体形成活动组件103,所述动子4与膜片1连接的一端部分外露于套筒202。
参见附图6至附图8,不可拆连接方式包括:动子4的一端部与膜片1的形心部位粘接连接,形成活动组件103。进一步地,动子4为金属材质结构件,膜片1是非磁化材质结构件或者金属件。当膜片1选用具有一定弹性的金属结构件时,动子4与膜片1选用焊接的固定连接方式。上述方案,动子与膜片粘接固定,简单的连接能极大地降低制造的难度和生产制的成本,契合实际的市场需求。
具体地,动子4包括运动部402,运动部402为金属材料的圆柱体结构件,运动部402朝向膜片1方向的端部设置有伞状或蘑菇形状的嵌入块401,膜片1内设有与嵌入块401配
合的安装固定件,将动子4与安装固定件配合连接形成的整体放置到模具中,在安装固定件的四周通过一体化注塑成型形成与动子4连接的膜片1。进一步地,膜片1的材质为塑料、橡胶、硅胶、动物皮等。进一步地,安装固定件具有耐高温的性能。进一步地,安装固定件选用金属材质的合金结构件。进一步地,一体化成型的动子4与膜片1连接的整体件,为固定连接不可拆卸。上述方案,以动子与安装固定件配合连接形成的整体作为膜片中心的支撑部件,模具内注塑形成与整体一体化的膜片结构,这种方案使动子与膜片的连接具有更高的可靠性,能使活动组件在长时间的使用后依然保持初始的位置关系,极大地提升了用于洗涤设备的自动投液装置的使用寿命,契合用户的实际使用需求。
参见附图9至附图14,可拆卸的连接方式包括:膜片1的中心部位具有一定的厚度,膜片1内设置有与嵌入块401卡接配合的嵌入部101,嵌入块401与嵌入部101配合卡接,实现动子4与膜片1的连接。卡接的连接方式更加可靠稳定,能极大的提升活动组件的结构强度,即在一定程度上提升了用于洗涤设备的自动投液装置的功能可靠性。进一步地,膜片1形状为盘状、碗状和囊状。
参见附图8至附图11,所述膜片随动子的往复运动,向吸液装置6的腔室和向套筒202方向具有不同的变形程度。优选地,所述膜片向吸液装置6的腔室的变形程度大于向套筒202方向的变形程度。因为套筒202侧的空间较小,对膜片的向左移动具有一定的阻碍,这样的方案,能防止出现磁场力过大致使膜片被拉坏的情况,保证了用于洗涤设备的自动投液装置的使用寿命。
在本实施例的另一种具体方案中,参见附图6,所述膜片向吸液装置的腔室的变形程度小于向套筒方向的变形程度,保证弹性元件不会因为过度拉伸而导致功能失效,同时此方案还能使膜片周期性的处于变化的状态,防止膜片反复受到换向的作用力而导致的疲劳破坏,因此在一定程度上保证了自动投液装置的性能可靠性和使用寿命。
参见附图11、附图13和附图14,动子4还包括哑铃形状的传导部403,传导部403的一端连接运动部402,另一端上设置有嵌入块401,嵌入块401与嵌入部101配合卡接,实现动子4与膜片1的连接。进一步地,上述的粘接、焊接、一体化成型、卡接和螺纹连接的动子4均可以设置便于连接的传导部403。进一步地,传导部403的材质按需可选用非金属材质或其他材质。
具体地,驱动装置5包括线圈501,线圈501绕设于套筒202的外侧,线圈501通电产生磁场,动子4受磁场的驱动在套筒202中往复运动,周期性的推动和/或拉动膜片1产生形变。上述方案,驱动装置5采用磁驱的方式,能减小用于洗涤设备的自动投液装置的体积和质量,磁驱线圈的成本较其他驱动方式低,以此可以降低生产的成本。进一步地,线圈501的中轴线与套筒202的中轴线重合。进一步地,膜片1由弹性材质制成,当动子4拉动或推动膜片1复位时,膜片因自身的弹性还会小幅度的前后波动,将集聚的能量释放彻底。这种方案可以使能量得到更大程度的利用,大大提升了能量利用效率和投放洗涤液的效率。进一步地,除磁驱方式外,驱动装置5也可以选择液压系统、气压系统带动的方式,使活动组件运动。需要说明的是,所述驱动装置5给予动子4提供的磁驱力,可以是方向始终固定不变的力,也可以是方向周期性变化的力。
参见附图6至附图8、附图10和附图12,套筒202远离膜片方向的一端设置有弹性元件3,弹性元件3与驱动装置5相互协助和/或制约动子4的运动,弹性元件3包括支撑弹簧301,支撑弹簧301与动子4同轴设置并有一端相连,当动子4发生移动时,支撑弹簧301对动子4产生与运动方向相同或相反的力,弹性元件3还包括反弹弹簧302,反弹弹簧302的长度不大于支撑弹簧301的长度,当动子4背离膜片1方向移动时,到某一位置动子4与反弹弹簧302接触,使动子4受到与运动方向相反的力,能使动子4速度降至零。进一步地,支撑弹簧301在自然状态下一端连接套筒202底部,另一端连接动子4的端部。进一步地,反弹弹簧302在自然状态下一端连接套筒202底部,另一端与动子4的端部有一定的距离。
参见附图13,膜片1的另一端设置有复位弹簧303,复位弹簧303一端连接膜片1的形心,使膜片1受拉或受推,始终向原位回复。上述方案,无论膜片是受拉或受推,设置于吸液腔602的复位弹簧始终给予活动组件一个与运动方向相反的复位力,这种方案能一定程度上避免出现膜片过度形变引起的疲劳破坏的情况,极大地提升了用于洗涤设备的自动投液装置的使用寿命。
需要说明的是,附图13可以理解为初始位置下的状态示意图,也可以理解为运动过程中的状态示意图,这里并未做出具体限制,因此附图反映的方案均成立。进一步地,复位弹簧303设置于吸液腔602中,复位弹簧303的一端连接膜片1的形变部位,另一端连接在吸液腔602内与膜片1对应的内壁上。进一步地,复位弹簧303可设置有多个,多个复位弹簧平行设置。
用于洗涤设备的自动投液装置的具体操作步骤:
洗涤设备内放入衣物,根据衣物确定所需的洗涤添加剂用量。自动投液装置根据所需的洗涤添加剂用量确定需要工作的通电时间,自动投液装置将洗涤添加剂投放到洗涤桶进水管中,并由进水带动较为均匀的添加到洗涤设备的洗涤外筒中。
需要说明的是,本实施例提供的自动投液装置可以将吸液腔中抽入部分洗涤剂后,再延时地将这部分洗涤液排出吸液腔投放到洗涤桶进水管中,也可以是将吸液腔中抽满洗涤液后,再整体地排出吸液腔投放到洗涤桶进水管中。这使得投放的洗涤剂剂量不会因投液装置吸液腔的大小而限定在某一范围,因此本实施例的投液装置具有极大的适用范围。
实施例九
本实施例与上述实施例八存在区别,所述的膜片与动子的可拆卸连接方式还包括:螺纹连接方式。膜片的中心部位具有一定的厚度,膜片内设置有内螺纹通道结构,动子的一端设置有凸出的螺纹杆,通过旋转将螺纹杆旋进内螺纹通道,实现动子与膜片的连接,或者,膜片外凸设置有螺纹杆,动子的一端内凹设置有内螺纹通道结构,通过旋转将螺纹杆旋进内螺纹通道,实现动子与膜片的连接。
实施例十
如图9至图11、图12和图14所示,本实施例为上述实施例八的进一步限定,所述的动子4与膜片1通过嵌入块401与嵌入部101实现卡接配合的具体方式如下:运动部402朝向膜片1方向的端部设置有伞状或蘑菇形状的嵌入块401,膜片1的中心部位具有一定的厚度,膜片1内设置有与嵌入块401卡接配合的嵌入部101,嵌入块401与嵌入部101配合卡接,实现动子4与膜片1的连接。进一步地,嵌入块401是具有刚性不可变形的伞状或蘑菇形状的结构件,膜片1的中心部位设置有开放的嵌入部101。装配时,动子4的中轴线平行于膜片1的中心线,动子4的嵌入块401平移卡入嵌入部101中,移动至动子4的中轴线重合于膜片1的中心线完成动子4与膜片1的卡接装配。或者,嵌入块401是具有弹性可变形的伞状或蘑菇形状的结构件,膜片1内设置有与嵌入块401卡接配合的嵌入部101。装配时,移动至动子4的中轴线重合于膜片1的中心线,将嵌入块401插入嵌入部101中,嵌入块401在嵌入部101中舒展开固定,完成动子4与膜片1的卡接装配。
实施例十一
如图6至8、图10和图12所示,本实施例为上述实施例八的进一步描述,所述的驱动装置驱动动子的具体原理如下:
初始时线圈未通电,动子无运动趋势,弹簧处于自然状态无压缩或拉伸,膜片无形变;
采用正弦交流电为例,将交流电的一个周期分为上半周期阶段和下半周期阶段,交流电的上半周期阶段和下半周期阶段电压图像(或电流图像)关于电压数值(或电流数值)为0的点中心对称;以上半周期和/或下半周期的电压峰值(或电流峰值)点为中点,将半周期分为电压强度升高(或电流升高)阶段和电压强度降低(或电流降低)阶段。
线圈通入交流电,动子不会被整体磁化,会被套筒左侧部分侧壁的敞口中外露的磁力线吸引向左移动。以动子为受力体分析,动子受磁场力F1和膜片的复位力F2以及弹簧的复位力F3作用而运动。
当交流电处于上半周期的电压强度升高阶段,处于初始位置的动子,受到向左的磁场力F1致使动子向左移动,向左移动的同时膜片的复位力F2和弹簧的复位力F3增大来阻止动子左移,此时膜片的复位力F2是对动子向右的拉力,弹簧的复位力F3是对动子向右的推力。随着电压的继续增大,动子受到向左的磁场力F1不断地增大,迫使膜片继续向左拉伸,膜片的复位力F2继续增大,弹簧继续压缩,弹簧的复位力F3继续增大。当到达电压峰值点,此时,动子受到向左的磁场力F1在数值上等于向右的膜片的复位力F2和弹簧的复位力F3的数值和,但是动子仍具有向左的动量,动子继续向左侧位移一定的距离,进一步地压缩了弹簧和拉伸了膜片,使向右的膜片的复位力F2和弹簧的复位力F3的数值和短时间内大于了动子受到向左的磁场力F1的数值,直至动子的速度减为零,此时动子受合力向右,动子有向右运动的趋势。
当交流电处于上半周期的电压强度降低阶段,处于左侧最远极限位置的动子,受到向右的膜片的复位力F2和弹簧的复位力F3的数值和大于动子受到向左的磁场力F1的数值,因此动子右移。动子向右移动的同时膜片的复位力F2和弹簧的复位力F3得到释放减小来致使动子右移,此时膜片的复位力F2是对动子向右的拉力,弹簧的复位力F3是对动子向右的推力。随着电压的继续降低,动子受到向左的磁场力F1不断地减小,膜片的复位力F2和弹簧的复位力F3得以继续释放减小致使动子右移。当到达上半周期与下半周期的转换点(即交流电电压数值为0、电压即将换向的转折点),此时,动子不在受磁场力(即磁场力F1为0),存储的膜片的复位力F2和弹簧的复位力F3也释放完全,此时动子不受外力,但是动子仍具有向右的动量,动子继续向右侧位移一定的距离。动子继续向右移动一定距离,这个过程中膜片被推动向右,此时膜片的复位力F2是对动子向左的推力,同时在这个过程中弹簧被动子带动拉伸,此时弹簧的复位力F3是对动子向左的拉力。直至动子的速度减为零,此时动子受到的合力向左,动子有向左运动的趋势。
此时如果将交流电停止,完成动子会在初始位置左右反复,直至将能量消耗殆尽。
此时如果保持交流电的接通,交流电进入下半周期的电压强度升高阶段,再进入下半周期的电压强度降低阶段,下一步进入上半周期的电压强度升高阶段,以此循环,即当交变电流频率50HZ,动子运动100个来回。
需要说明的是,交流电进入下半周期的电压强度升高阶段受到的力分析与交流电进入上半周期的电压强度升高阶段相同;交流电进入下半周期的电压强度降低阶段受到的力分析与交流电进入上半周期的电压强度降低阶段相同,这里不再做赘述。
实施例十二
如图6至8、图10和图12所示,本实施例与上述实施例十一存在区别,所述的驱动装置驱动动子的另一种具体原理如下:采用正弦交流电为例,当交流电处于上半周期阶段,线圈生成上N下S的磁极(当然根据电流方向的不同,也可能是上S下N),动子部分与敞口部位在高度方向上部分重合,线圈敞口部位的外漏磁力线将动子完全磁化形成上S下N的磁极。过程随着电压先高后低,线圈形成的磁极强度先强后弱直至消失,因此动子的磁性也表现为先高后低。动子上端受到的线圈N极的吸引力和S极的排斥力均指向上,动子下端受到的S极向上的吸引力远远大于收到N极向下的排斥力,因此动子向上运动,最终在一个相对稳定的位置速度减为零。动子向上运动的过程受到方向向上的加速度从零增至某值,后减为零。
当交流电处于周期中点时,动子现处于相对稳定状态,无磁极分布的磁场。当交流电处于下半周期阶段,线圈生成上S下N的磁极,线圈敞口部位的外漏磁力线将动子磁化形成上N下S的磁极。过程随着电压的大小先高后低,线圈形成的磁极强度先强后弱直至消失,因
此动子的磁极也表现为先高后低。在磁极吸引力的作用下(设置有复位弹簧,复位弹簧也发挥作用),弹簧向下的拉力加线圈S极对动子下端向下的排斥力大于线圈S极对动子上端的吸引力和线圈N极对动子上端向上的排斥力和线圈N极对动子下端向上的吸引力,因此动子向下运动,最终停留在一个相对稳定的位置复位。这种方案,能起到磁场抵消的作用。
根据所需的洗涤添加剂用量,确定通电时间,实现洗涤剂的精准投放。
实施例十三
如图6至8、图10和图12所示,本实施例与上述实施例十一存在区别,所述的驱动装置驱动动子的另一种具体原理如下:以直流电为例,当线圈的绕制匝数和通入的电流强度固定不变时,向线圈中通入直流电,就会瞬时产生强度和方向都不变的磁场。此时,动子在该磁场中受到的力一直保持不变,动子逐渐压缩弹簧的过程中,受到的弹力不断变大直至与磁力平衡,动子最终会静止在平衡位置。若要使动子往复不断地带动膜片同时防止线圈烧坏,需要使该磁力以一定的频率出现和消失,也就是说使磁力总是在动子的运动方向与磁力方向一致时出现,不一致时消失,即磁力总是对动子做正功。
实施例十四
如图6至8和图12所示,本实施例为上述实施例八的进一步描述,所述的弹性元件的具体调节过程如下:具体地,套筒202远离膜片方向的一端设置有弹性元件3,弹性元件3与驱动装置5相互协助和/或制约动子4的运动,弹性元件3包括支撑弹簧301,支撑弹簧301在自然状态下一端连接套筒202底部,另一端连接动子4的端部。弹性元件3还包括反弹弹簧302,反弹弹簧302的长度不大于支撑弹簧301的长度,反弹弹簧302在自然状态下一端连接套筒202底部,另一端与动子4的端部有一定的距离。进一步地,初始状态下支撑弹簧301和反弹弹簧302均不受拉伸力和压缩力,且反弹弹簧302不接触动子4。
当动子4向靠近膜片1方向移动时,动子4拉动支撑弹簧301,支撑弹簧301给予活动组件103一个与运动方向相反的拉力,随着运动的持续进行这个拉力越来越大;当动子4将膜片1推动变形至某一程度,动子4的速度降为零;动子4受到膜片1的复位推力和支撑弹簧301的拉力和驱动装置5的驱动,动子4向背离膜片1的方向移动。动子4向背离膜片1的方向移动至支撑弹簧301初始状态点时,动子4的速度仍不为零;当动子4背离膜片1方向移动至与反弹弹簧302接触,使动子4受到与运动方向相反的力瞬间的增大,某一位置点使动子4速度降至零;此时,动子4受到驱动装置5、支撑弹簧301和反弹弹簧302的作用力以及膜片1的复位拉力均指向靠近膜片1的方向,动子4向靠近膜片1的方向运动,以此循环往复。
实施例十五
本实施例为上述实施例八的进一步描述,所述的膜片还可以有如下具体结构:
参见附图12,碗状膜片1设置于壳体2和吸液装置6的连接处,连接结构与上述实施例相同的方案在这里不做赘述。
具体地,碗状膜片1与壳体2和吸液装置6的连接方式可以设置为粘合性连接。在用于洗涤设备的自动投液装置内壁形成一个胶粘区,在碗状膜片1外周设置粘合处,将碗状膜片1外周粘合处与用于洗涤设备的自动投液装置内壁的胶粘区贴合,碗状膜片1的凸面朝向套筒202方向设置,外周壁的端部与碗状膜片1的凸面高点平齐或突出。碗状膜片1自外周至端部形成逐渐收紧的球状曲面结构,碗状膜片1与用于洗涤设备的自动投液装置之间形成两个互相隔离的腔室。碗状膜片1外周围合的范围同时包括进液口与出液口的腔室为吸液腔602,另外一个腔室为隔离腔室。上述隔离腔室的设置,给予膜片1更大的运动范围,同时碗状的设计使得吸液装置6能容纳更多的洗涤液,提升用于洗涤设备的自动投液装置的工作效率。
参见附图14,囊状膜片1设置于壳体2和吸液装置6的连接处,连接结构与上述实施例相同的方案在这里不做赘述。所述囊状膜片1具有弯折结构件102,所述的弯折结构件102
为折叠波纹管形式。所述的弯折结构件102可以根据受力的方向不同,做出一定程度的拉伸或压缩。上述弯折结构件102的设计,能起到协助改变吸液腔602容积的作用,使得吸液腔602的容积变化程度更大,实现将更多的洗涤液吸入吸液装置6和排出吸液装置6,提升了用于洗涤设备的自动投液装置的工作效率。
实施例十六
如图15至图18所示,本发明所述的一种洗涤设备自动投液装置,包括套筒202、动子4以及驱动装置5。
所述套筒202的一端封闭,另一个端部具有吸液管603和排液管204,所述套筒202的另一端部上的吸液管603和排液管204交替打开。所述动子4可移动地设置于所述套筒202中。
所述驱动装置5设置于所述套筒202的外侧,用于驱动所述动子4在所述套筒202中移动。
所述动子4在所述套筒202内往复振荡,使所述套筒202内的液体产生波动,波动的液体沿着所述套筒202轴向流动并周期性的从所述排液管204流出。
本发明中,所述套筒202为中空结构,在其中一个端部上开设有吸液管603安装口和排液管204安装口,其中所述吸液管603和所述排液管204密封插设在对应的吸液管603安装口和排液管204安装口上。具体的,所述吸液管603和所述排液管204与各自安装口的固定方式也可以采用螺纹连接的方式。
所述套筒202中的吸液管603和排液管204可以在驱动装置5作用所述动子4来回振荡时,交替打开吸液管603和排液管204,从而形成单向的排液通道,实现将液体向洗衣机内部添加。
所述动子4为形状、体积相对固定不变化的柱状金属结构件,可以为铁质金属,且所述动子4内部可以是空心或者局部空心的设置。其中,所述动子4初始状态下自身不具有磁性,会在磁场的吸引下磁化并被吸引发生运动位移。所述动子4设置在所述套筒202中,并且可以在所述套筒202的内部中进行滑动。在所述套筒202的外侧设置有所述驱动装置5,在所述驱动装置5的作用下,使得所述动子4可以在套筒202中移动。
由于所述动子4在所述套筒202中高频振荡进行往复运动,从而使所述套筒202中的液体产生动能形成速度波。获能的液体以波的形式在所述套筒202中移动,液体流动到所述排液管204处并打开所述排液管204,通过所述排液管204向洗衣机内部进行注水。由于所述套筒202中排出部分液体,其内部形成负压,使得通过所述吸液管603向所述套筒202中补充液体。如此反复动作,可以实现向洗衣机中周期性连续进行注液作业,投液量精准、高效。
优选的,所述驱动装置5驱动所述动子4的方式可以是电动机械式、气动式或者电磁式中的其中一种,在驱动作用下,所述动子4在所述套筒202中连续往复振荡。
其中,采用电动机械式的驱动方式驱动所述动子4进行往复移动,其具体方式是:所述动子4内部设置有微型直线振动电机,通过微型直线振动电机的振动方向与所述动子4移动的方向一致,从而可以达到所述动子4在所述套筒202中连续地进行高频往复振荡,从而使得所述套筒202中的液体获能产生波动,实现进排液的动作。所述动子4振幅较小,频率较高,会使得所述动子4高频振荡起来,带动液体产生波动的频率较高。
另外,采用气动式的驱动方式驱动所述动子4进行往复移动,其具体方式可以是:所述动子4外侧套设有套管,所述动子4在所述套管中密封滑动设置,所述套管中设有用于输入和排放气体的开口。通过改变套管内部的气压,而改变所述动子4的移动位置,提高改变频率,从而可以达到所述动子4在所述套筒202中连续地进行高频往复振荡,从而使得所述套筒202中的液体获能产生波动,实现进排液的动作。气动式的驱动方式使得所述动子产生的往复移动的动作更加稳定,从而保证周期性投液过程中,单次投液量均匀。
优选的,采用电磁式的方式时,所述驱动装置5包括线圈501和弹性元件3。
所述线圈501绕设于所述套筒202的外侧。
所述弹性元件3轴向设置于所述套筒202内壁上,用于提供所述动子4向初始位置移动的恢复力。
优选的,初始状态下,所述动子4的中心偏离所述线圈501的中心设置。
所述驱动装置5包括线圈501,所述线圈501绕设于所述套筒202的外侧。初始状态下,所述动子4的中心偏离所述线圈501的中心设置。且所述动子4与所述线圈501两者中心的连线的水平距离大于所述动子4朝向所述线圈501的中心振荡的最大振幅。
另外,所述线圈501也可以单独在所述套筒202的外侧设置有线圈支架502,将所述线圈501绕设在所述线圈支架502上,实现所述线圈501与所述套筒202的可拆卸式设置。所述线圈支架502可以根据需求,对其位置进行适应性调整,设置更加灵活。
在所述套筒202的内壁上设置有弹性元件3,且所述弹性元件3呈轴向设置。即所述弹性元件3的伸缩方向可以沿着所述套筒202的轴向方向设置,但可以不完全垂直于所述套筒202的端部。
所述动子4在所述套筒202中受到所述驱动装置5的驱动下进行高频振荡后,在所述弹性元件3的作用下进行复位。则通过所述驱动装置5和所述弹性元件3的双重作用下,所述动子4形成连续的高频往复移动动作。
具体的,通过设置所述弹性元件3的弹性系数与所述动子4的质量的比值来实现所述动子4与所述弹性元件3组成的振荡系统的振动频率。具体的,所述弹性元件3的弹性系数远大于所述动子4的质量,从而可以提高整个振荡系统的振动频率。则所述动子4在所述驱动装置5的驱动下,在所述套筒202中实现高频的往复振荡动作。通过电磁式的驱动方式驱动所述动子4进行高频往复振荡,其中设置的结构简单紧凑,成本较低;且驱动所述动子4移动的驱动力所需的所述线圈501等部件不与其直接连接,仅仅需要所述弹性元件3进行复位,从而没有较大的挤压力和摩擦力,保证所述动子4的使用寿命。
优选的,所述动子4与所述吸液管603相靠近的端面与所述套筒202的内端面之间存在间隙,所述间隙大于等于所述动子4朝向所述吸液管603振荡的最大振幅。
所述动子4设置在所述套筒202中,其中在所述弹性元件3与所述套筒202的一端连接后,所述动子4的另一端与所述套筒202的另一端内部之间具有间隙。
所述动子4在所述套筒202中往复振荡过程中,当所述动子4向靠近所述吸液管603的一端移动时,所述动子4不与其端部的侧壁相接触或刚好接触。即所述动子4向靠近所述吸液管603的一侧移动的最大振幅小于等于该间隙。保证所述动子4在振荡过程中不会撞击在所述套筒202的端部的内壁上。
另外,在初始设置时,所述动子4的一端面与具有所述吸液管603的所述套筒202的内端面之间留有一定的间隙,可以使得间隙处填充有液体。一方面保证在向排液管204排液时,有一定量的液体可以进入洗衣机中;另一方面,留有一定的间隙,可以保证液体受所述动子4高频振荡而逐渐获能产生速度波,并形成单向液柱的流动趋势。
初始状态下,即未通电状态下,所述线圈501的中心与所述动子4中心相偏离。即所述线圈501轴向长度的中垂线与所述动子4轴向长度的中垂线不重合。所述线圈501绕设的整体长度对应的中垂线处于所述动子4轴向长度的中垂线的左侧或者右侧。
以所述动子4轴向长度的中垂线处于所述线圈501的右侧时,所述线圈501通入交流电时,由于交流电的特性,其电流的大小、方向呈周期性变化,具体的电流的波形呈正弦波形,由于电流大小的周期性变化,使得产生的磁场会产生周期性的变化,进而对处于所述套筒202中的吸引力同样存在周期性的变化。
在向所述线圈501中通入该正弦交流电。在正弦波形的一个周期过程中,所述动子4始
终受到所述线圈501提供的大小变化、磁力方向一致的电磁力。其中所述动子4所受的电磁力的方向始终指向所述线圈501的中心。
在开始状态下,电磁力驱动所述动子4向左侧运动,并开始挤压所述弹性元件3,则电磁力对所述动子4做功转化为所述弹性元件3的弹性势能,使得电磁力始终促进所述动子4运动,对所述动子4做正功。
到所述动子4运动到最左侧停下后,所述弹性元件3开始释放自身的弹性势能,转化为所述动子4的动能,使其开始向右侧运动,此时电磁力阻碍所述动子4运动,对所述动子4做负功,到所述动子4运动到最右侧停下。
在正弦交流电的连续周期下,所述动子4会在所述套筒202中高频往复进行振荡运动,从而使得所述套筒202中的液体获能波动。从而液体以波动的形式向朝向所述排液管204的一侧移动进行排液,排液后,所述套筒202内形成负压并从所述吸液管603进行吸液。
其中一个优选的实施例中:当所述线圈501通入正弦交流电时,以电流的整个正向波形为半个周期为例。所述线圈501电流导通,电流从0逐渐增强至最大值,磁场强度不断增强,使得所述动子4受到的电磁力不断增加并向所述套筒202的左侧移动,所述动子4压缩弹性元件3使得其恢复力不断增加,此阶段电磁力始终大于恢复力,则所述动子4在所述套筒202中做加速度不断减小的加速运动。
当电磁力等于恢复力时,加速度为0,此时所述动子4的速度最大;所述动子4继续向左运动,恢复力大于电磁力,则所述动子4开始做减速运动直至为0,此时所述弹性元件3的压缩量最大,所述动子4开始做反向加速运动,即所述动子4向所述套筒202的右侧移动,电流由最大值开始向0逐渐减弱,整个过程与上述所述动子4向所述套筒202左侧移动的运动状态一致,则所述动子4在半个周期中完成一次往复运动,其反向波形中的所述动子4的运动状态与上述一致。
参考图15,另外一个更优选的实施例:当所述线圈501通入正弦交流电时,以电流的整个正向波形为半个周期为例。所述线圈501电流导通,电流从0逐渐增强至最大值,磁场强度不断增强,使得所述动子4受到的电磁力不断增加并向所述套筒202的左侧移动,所述动子4压缩弹性元件3使得其恢复力不断增加,此阶段电磁力始终大于恢复力,则所述动子4在所述套筒202中做加速度不断减小的加速运动。
当电磁力等于恢复力时,加速度为0,此时所述动子4的速度最大;所述动子4继续向左运动,电流从最大值开始逐渐降为0,所述弹性元件3的恢复力大于电磁力,则所述动子4开始做减速运动直至为0,此时所述弹性元件3的压缩量最大,所述动子4开始做反向加速运动,即所述动子4向所述套筒202的右侧移动,其中所述动子4向左侧移动与向右侧移动所需的时间周期一致。在所述动子4向右侧移动的过程中,电磁力先逐渐减小后在逐渐增大,但整体电磁力对所述动子4做负功最少。
则所述动子4与所述弹性元件3的振荡周期与上述正弦电流的周期即电磁力的变化周期相同或者呈倍数关系时,会产生共振,使得所述动子4在电磁力的驱动下振荡的幅度最大,则有效保证吸排液的效果。由于持续的交变电流的作用,使得所述动子4可以在所述套筒202中高频振荡,进而使得整个吸排液的动作连续进行。
整体来说,通过控制交流电频率与所述动子4和所述弹性元件3形成的振荡系统的振动频率之间的关系,可以控制所述动子4在所述套筒202中的振荡幅度,进而保证吸排液的效果。所述动子4在高频的振荡中,会快速的往复振动并带动所述套筒202内部的液体产生速度波,从而向所述排液管204的一侧排液。在排液后,所述套筒202内部形成负压,从吸液管603处吸液进入所述套筒202中,保证整个投液动作连续进行,则实现向洗衣机中投放洗涤液的动作。
优选地,所述线圈501的轴线与所述动子4的轴线相平行,所述动子4的外径大小小于所述套筒202的内径大小。所述动子4与所述线圈501两者中心的连线的水平距离大于等于
所述动子4朝向所述线圈501的中心振荡的最大振幅。
所述动子4滑动设置于所述套筒202时,可以将其完全水平放置,从而所述动子4的轴线可以与所述线圈501的轴线相平行设置。从而可以在磁场作用下,所述动子4所受到的吸引力的合力最大,同时移动也更加稳定。
所述动子4和所述线圈501的空间上存在的两个中点,将两个中点的连线的水平分量对应的距离大于等于所述动子4朝向所述线圈501的中心一侧的振荡的最大振幅。在所述动子4朝所述线圈501的中心移动时,避免所述动子4的中心越过所述线圈501的中心,而导致磁力方向发生改变的情况,进而保证所述动子4振荡效果。
优选地,所述线圈501、所述动子4以及所述套筒202三者之间的轴线相重合设置。
本发明中,通过将所述线圈501、所述动子4以及所述套筒202三者同轴设置,可以保证所述动子4在套筒202中的移动不会受到所述套筒202内部的摩擦影响。同时,保证磁场作用在所述动子4上产生的吸引力在各个方位上是均匀的,进而使得所述动子4移动的动作更加稳定。
优选地,所述动子4沿着所述套筒202轴向方向上的投影将所述排液管204的管口全部遮挡。
所述动子4与所述排液管204的管口相对,沿着水平方向进行延伸时,所述动子4完全可以覆盖排液管204的管口,则可以在液体波动时,尽可能多的液体从所述排液管204中排出。
优选地,所述动子4的两端分别设置有凸台。
所述动子4的两端设置有凸台,其中凸台上设置有圆角,从而可以减小所述动子4高频往复振荡时的阻力。
优选地,所述弹性元件3包括支撑弹簧301,所述支撑弹簧301的一端与所述套筒202的内壁连接,另一端与所述动子4的外侧壁连接。所述支撑弹簧301的最大压缩量小于等于所述动子4振荡的最大振幅。
参照图15和3,所述支撑弹簧301采用压缩弹簧。作为其中优选的方案,所述支撑弹簧301设置于与所述排液管204相对的所述套筒202的内端面上。具体的,所述支撑弹簧301与所述动子4同轴设置,且由于所述动子4的端面上设置有凸台,所述支撑弹簧301的一端卡紧固定在凸台上。由于同轴设置,可以保证所述动子4在所述套筒202中,水平地处于其轴心上,既完成了所述动子4的安装固定,同时也给所述动子4在受磁场吸引移动后提供恢复力。
另外,由于所述支撑弹簧301的最大压缩量大于等于所述动子4振荡的最大振幅,在所述动子4振荡过程中,由于往所述线圈501的中心一侧移动会压缩所述支撑弹簧301,避免所述动子4还未移动到最大振幅时,所述支撑弹簧301就被压缩至最大压缩量处,影响整体振荡的效果。
进一步地,参照图16和4,所述动子4在远离所述支撑弹簧301的另一端面上设置有复位弹簧303,其中复位弹簧303与支撑弹簧301的安装位置以及固定方式完全相同。从而可以对所述动子4两端进行相应的安装固定,进一步保证其安装后的水平状态。
优选地,所述弹性元件3还包括反弹弹簧302,所述反弹弹簧302的一端与所述套筒202的内壁连接,所述支撑弹簧301套设在所述反弹弹簧302的外部。所述反弹弹簧302的弹性系数大于所述支撑弹簧301的弹性系数。所述反弹弹簧302的最大压缩量大于等于所述动子4振荡的最大振幅。
所述反弹弹簧302设置于所述支撑弹簧301的内部,与所述支撑弹簧301组成弹簧谐振系统,可以在所述动子4被磁场吸引后逐渐压缩支撑弹簧301,继续压缩后会与反弹弹簧302进行挤压。同样,所述动子4振荡的最大振幅小于所述反弹弹簧302的最大压缩量,避免所
述动子4未到达最大振幅处即被反弹,影响整体振荡的效果。
由于所述反弹弹簧302与所述支撑弹簧301的外径以及弹性系数不同,从而所述反弹弹簧302与所述支撑弹簧301之间可以配合组成的弹力范围更大,有效缩短单根弹簧需要提供一定恢复力的长度,可以更好的适应于所述动子4移动后所需要提供的恢复力。
优选地,所述吸液管603与所述排液管204位于所述套筒202的同侧。将所述吸液管603与所述排液管204设置在所述套筒202的同侧,可以使得液体吸入并排出的路程缩短,更加有效率的给所述洗衣机内部添加洗涤液等。
具体的,所述吸液管603和排液管204中设置导向装置,所述导向装置为单向阀206,位于所述吸液管603上的所述单向阀206的导通方向由所述吸液管603指向所述套筒202内部,位于所述排液管204上的所述单向阀206的导通方向由所述套筒202内部指向所述排液管204。从而可以有效控制液体从所述吸液管603流入所述套筒202中、并从所述排液管204中排出。
本发明中,在所述吸液管603和所述排液管204的内部设置有单向阀206,从而可以保证抽吸和排放液体的方向,可以完全保证液体从吸液管603被吸取并从所述排液管204中排出,避免吸入所述套筒202中的液体在排液时部分重新回流到所述吸液管603中,影响向所述洗衣机投液的效率。
进一步的,本发明中的所述线圈501同样可以通入直流电。
以直流电为例,当所述线圈501中通直流电时,并以一定频率控制电流的通断。
当所述线圈501的绕制匝数和通入的电流强度固定不变时,向所述线圈501中通入直流电,就会瞬时产生强度和方向都不变的磁场。此时,所述动子4在该磁场中受到的力一直保持不变,所述动子4逐渐压缩所述支撑弹簧301的过程中,受到的弹力不断变大直至与电磁力平衡,所述动子4最终会静止在平衡位置。
使所述动子4往复振荡运动,需要使该电磁力以一定的频率出现和消失,导通所述线圈501的电流时,所述动子4的运动方向与电磁力方向一致;断开所述线圈501的电流时,所述动子4在所述支撑弹簧301的作用下回弹。进而通过控制所述线圈501通断的频率,同样可以实现所述动子4在所述套筒202中振荡运动。
具体的,所述套筒202包括套筒本体和端盖601组成,其中套筒本体具有敞口,所述套筒本体的敞口处与所述端盖601对接,从而使得内部形成管径处处相等或者管径不全相等的套筒腔203。当管径一定时,所述动子4在高频往复振荡,带动液体获能波动,在套筒腔203中波动稳定,吸排液的量可以得到保证;而当形成的管径不全相等时,即所述端盖601部分的管径较大,能够在初始储存更多的液体。但是,液体获能波动时,到达所述端盖601处压强减小,导致打开排液管204中的单向阀206的能量较小,排液量减小,进而所述套筒202中形成的压力差较小,导致吸液量减小。优选的,所述套筒本体与端盖601形成的套筒腔203的管径处处相等。
其中端盖601与套筒本体2固定连接,固定方式可以是螺栓连接、粘接或者焊接。优选的,所述端盖601与套筒本体之间采用螺栓固定,便于拆卸。
进一步地,所述套筒本体和端盖601的外周壁上固定套设有翻边201,从而给所述套筒本体与端盖601通过螺栓固定时提供安装部位。且两个翻边201之间设置有密封圈,保证套筒本体和端盖601在连接处的密封性能。
本发明还提供一种具有上述任一所述的洗涤设备自动投液装置的洗涤设备。具体使用时,其中该自动投液装置应用于洗涤装置中,具体的可以是洗衣机、洗碗机或者洗烘一体机等等设备。以洗衣机为例,该自动投液装置的吸液管603与洗涤剂储液盒相连,所述排液管204可以直接与洗衣机的内筒连通,在排液管204投液过程中可以与进水管排入的水混合一同投入洗衣机的内筒中。
在洗衣过程中,通过上述的线圈501给所述动子4提供电磁力进行驱动,并通过弹性元件3进行复位。不断往复上述振荡动作,从而使得所述套筒202中的液体获能被振荡起来,则所述套筒202中的液体波动位移。从而在通过所述排液管204向洗衣机内部投液的同时,所述套筒202内部产生压强差使得吸液管603的单向阀206打开进行吸液,则可以保证连续不断向洗衣机内筒中投入所需的液体,操作简单、投液精准。
实施例十七
如图19至图25所示,本发明提出了一种洗涤设备自动投液装置,用于实现对洗涤液的进液、出液,对洗涤液进液是指,使洗衣机中的多种洗涤液进入到洗涤设备自动投液装置中,对洗涤液出液是指,将洗涤设备自动投液装置中的洗涤液投出至洗衣机。本发明的洗涤设备自动投液装置包括壳体2,壳体2内设有套筒202,套筒202具有套筒腔203,本发明对洗涤液的进液、出液包括,使洗涤液进入套筒腔203,实现对洗涤液的进液,使洗涤液由套筒腔203排出至洗衣机内桶,实现对洗涤液的出液,对洗涤液的进液、出液,同时进行。
套筒腔203呈长筒状,套筒腔203的外周设有线圈501,套筒腔203内设有设有动子4和弹性元件3,套筒腔203的两端分别连接有吸液管603和排液管204。吸液管603和排液管204分别位于动子4的两侧,吸液管603连接洗衣机的洗涤液存放盒/存放腔,排液管204连接洗衣机的洗涤筒。洗涤液存放盒/存放腔中的洗涤液,由吸液管603进入到套筒腔203中,由排液管204排出套筒腔203。
壳体2、套筒202分别具有敞口,且壳体2与套筒202的敞口同侧设置,壳体2的敞口处安装有用于封闭该敞口的端盖601,端盖601与壳体2固定连接,端盖601分别将壳体2和的套筒202的敞口封闭,使套筒202的内部形成套筒腔203,使壳体2的内部形成安装腔205。吸液管603和排液管204分别设置在端盖601上和壳体2上。
优选的,壳体2的敞口处设还有翻边201,端盖601与翻边201贴合,并固定安装在翻边201上。线圈501设置在安装腔205内,安装腔205内设有安装支架,线圈501固定在安装支架上。
本发明对洗涤液进液、出液的原理为:
通过动子4在套筒腔203中往复振动,带动套筒腔203中的洗涤液波动,洗涤液波动具有一定的振幅,可使得套筒腔203内的洗涤液,获得沿套筒腔203轴向的振幅,使洗涤液沿套筒腔203轴向移动,并通过排液管204排出套筒腔203,实现对洗涤液的出液;
如图19所示,排液管204和吸液管603内均设有单向导通结构,通过该单向导通结构,洗涤液通过吸液管603单向进入套筒腔203,套筒腔203中的洗涤液通过排液管204单向排出,单向导通结构包括单向阀206、具有单向导通功能的膜片、瓣膜等,结构简单,导通效果好。当然,为了实现吸液管603和排液管204的开通/断开还可以在液管内设置其他控制部件,例如:控制阀、其他单向阀等等的结构。
为了节约成本,还可以,如图22和图23所示,仅在吸液管603、或排液管204内设有单向导通结构,同样可以实现将洗涤液等自吸液管导流进套筒腔203、受动子4往复振动而驱动流向排液管204的使用目的。
由于洗涤液仅能由吸液管603单向进入套筒腔203,以及由排液管204单向排出套筒腔203,在动子4的不断振动下,波动的洗涤液不断由排液管204排出套筒腔203,由于洗涤液具有一定的黏性,由排液管204排出套筒腔203的洗涤液,会拉动套筒腔203中的洗涤液不断向排液管204方向移动,以及,洗涤液向排液管204方向移动的过程中,会拉动吸液管603中的洗涤液,不断进入到套筒腔203中,构成循环,使得套筒腔203中不断地有洗涤液进入,以及不断地有洗涤液排出套筒腔203,由此实现对洗涤液的进液、出液。
优选的,可使洗涤液依靠自身的重力通过吸液管603进入到套筒腔203中,使得进入套筒腔203中的洗涤液具有一定的压力,并且,控制该压力,使压力不足以打开排液管204内
的单向阀206,需依靠动子4振动,带动洗涤液波动,在洗涤液的波动和压力共同作用下,将排液管204内的单向阀206打开,实现对洗涤液的出液。
对于套筒腔203中的洗涤液的压力,还可以通过设置加压装置,控制套筒腔203中洗涤液,使其具有适当的压力,通过对套筒腔203中洗涤液施加压力,一方面可以降低通过洗涤液波动打开单向阀206所需压力,降低通过动子4振动打开单向阀206的难度,无需动子4以较大的振幅振动,以提升液体波动的压力,可以在较小振幅振动的情况下将单向阀206打开,节约电能,节约成本,另一方面,可使动子4高频振动,带动洗涤液波动,使洗涤液以较小的波动振幅打开单向阀206,洗涤液出液更加平稳,洗涤液以高频波动出液,每次少量出液,通过高频、少量出液一方面弥补了单次出液量小的问题,另一方面可以使洗涤液的投放更加精细,可控性更好,投放量更准确。
本发明动子4在套筒腔203中往复振动的原理为:
动子4至少部分由导磁物质构成,可设置为金属棒等,以使得动子4受线圈产生的磁场作用而产生磁驱力;当然,为了减小动子4的质量,可以将动子4设置为空心、局部镂空等结构。动子4在线圈501的磁驱力和弹性元件3的弹力作用下,沿套筒腔203的轴向往复振动。
本发明通过向线圈501通入直流电或交流电,并配合弹性元件3驱动动子4在套筒腔203内做往复振动,下面通过具体的实施例分别对线圈501通入直流电和交流电进行说明。
本发明实施例中,洗涤设备自动投液装置的一种实施方式如下:
向线圈501通入直流电,线圈501沿动子4的周向环绕动子4设置,线圈501构成闭合回路。线圈501通电后产生磁场,磁场对动子4产生吸引力,该吸引力作为线圈501对动子4的磁驱力。
磁驱力驱动动子4朝向弹性元件3移动,并挤压弹性元件3。通过控制电流的大小,可间接控制磁驱力的大小,可增加或减小线圈501的磁驱力,通过控制电流的通断,可使线圈501产生对动子4的磁驱力,或者使磁驱力消失。弹性元件3受到挤压后,发生形变,当弹性元件3受压到达极限位置时,反弹力最大,弹性元件3不可再被压缩,动子4停止移动,动子4受力平衡,此时,控制线圈501断电,或降低线圈501的磁驱力,打破动子4的受力平衡,使弹性元件3反弹动子4,使动子4沿背离弹性元件3反向移动,动子4发生反向移动后,控制线圈501通电,或增加线圈501的磁驱力,使动子4受到线圈501的磁驱力,正向移动,如此循环,使动子4不断受到磁驱力和反弹力,沿着套筒腔203的轴向往复振动。
本发明实施例中,洗涤设备自动投液装置的还一种实施方式如下:
向线圈501通入交流电,线圈501沿动子4的周向环绕动子4设置,线圈501构成闭合回路,由于交流电不断变化,导致线圈501的磁驱力不断变化,通过交流电对动子4驱动的原理为:
在交流电的一个周期内,具有两个电流/电压的峰值,处于电流/电压峰值时,线圈501对动子4的磁驱力最大。
在第一个四分之一周期内,电流由零逐渐达到峰值,磁驱力由零逐渐增大到最大值,在磁驱力不断增大的过程中,动子4对弹性元件3的压缩量逐渐增大,即磁驱力驱动动子4不断挤压弹性元件3,朝向弹性元件3移动,实现了对动子4的正向驱动;
在第二个四分之一周期内,电流由最大值逐渐降低到零,磁驱力不断减小,动子4在弹性元件3的反弹力作用下,背离弹性元件3移动,通过反弹力驱动动子4,实现了对动子4的反向驱动。
动子4同时受到磁驱力和反弹力,在第一个四分之一周期内,磁驱力与反弹力的合力驱动动子4正向移动,在第二个四分之一周期内,磁驱力与反弹力的合力驱动动子4反向移动。
以上所述是通过交流电对动子4驱动依据的原理,在实际情况中,由于动子4往复运动,
具有正向或反向的速度;
在第一个四分之一周期内,磁驱力不断增大,动子4不断正向移动,并具有正向的速度,当磁驱力达到峰值并即将减小时,即第一个四分之一周期结束的时刻,由于动子4具有正向的速度,动子4继续正向移动,由第一个四分之一周期结束时始,至动子4正向移动的速度为零时止,这段时间可称为“制动时间”制动时间,占用第二个四分之一周期的时间,即在第二个四分之一周期开始的一段时间,动子4并非沿反向移动,而是继续沿正向移动,直至速度降低为零;
而第二个四分之一周期的作用是,通过弹性元件3驱动动子4反向移动,为使动子4获得较好的往复振动效果,需要适当控制“制动时间”,至少要使“制动时间”小于一个四分之一的周期;避免整个周期内动子4持续正向移动,无法反向移动,导致动子只能单向移动,无法往复移动,无法通过往复振动进液、出液。
通过调整弹簧的弹性系数、磁驱力大小、动子4的质量、往复振动的位移长度,即可控制“制动时间”为合适的时长。
通过合适的“制动时间”,可以控制每一个四分之一周期内动子4沿正向移动的时间或沿反向移动的时间,即控制动子4在每一个二分之一周期内完成一次往复振动。
动子4在每一个二分之一周期内完成一次往复振动,在整个周期内完成两次往复振动。
优选的,通过线圈501的磁驱力和弹性元件3的反弹力,使动子4活动设置在套筒腔203的中部,使动子4在套筒腔203的中部区域内振动,使套筒腔203内动子4的两侧的洗涤液均受到动子4的振动作用,使动子4的振动效果最大化,利于洗涤液的进液、出液。
如图19至图25所示,本发明实施例中,动子4呈柱状,动子4的外径小于套筒腔203的内径,且动子4的长度小于套筒腔203的长度,动子4与套筒腔203同轴设置,动子4的外周与套筒腔203的内壁间隔设置,动子4的外周与套筒腔203的内壁之间形成可供洗涤液通过的导流通道2031。
动子4沿套筒腔203的轴向,将套筒腔203分隔成进液腔207和出液腔208,进液腔207和出液腔208分别位于动子4的两侧,导流通道2031连通进液腔207和出液腔208。进液腔207连接有吸液管603,出液腔208连接有排液管204,洗涤液由吸液管603进入进液腔207,由进液腔207通过导流通道2031进入出液腔208,通过排液管204排出出液腔208,在套筒腔203内,洗涤液沿套筒腔203的轴向,在动子4的振动作用下,由吸液管603单向流动至排液管204。
如图19所示,弹性元件,3包括支撑弹簧301和反弹弹簧302,支撑弹簧301设置在出液腔208和/或进液腔207中,支撑弹簧301的两端分别连接动子4和套筒腔203的内壁,支撑弹簧301对动子4起到限位、支撑的作用,通过支撑弹簧301,一方面,可以限定动子4在套筒腔203中的所在区域,使动子4处于套筒腔203的中部区域,另一方面,可对动子4提供一定的竖向支撑力,即向动子4提供沿套筒腔203径向的支撑力,使动子4悬浮在套筒腔203中,动子4的外周与套筒腔203的内壁不发生接触,使动子4的外周与套筒腔203的内壁相互间隔,使二者之间形成的导流通道2031呈围绕动子4外周的环状。
通过环状的导流通道2031,可以使进液腔207中的洗涤液,通过导流通道2031沿动子4的外周均匀进入出液腔208,洗涤液流动更加均匀,导致对洗涤液的进液、出液更加平稳,更加可控,出液效果好。
如图19所示,反弹弹簧302设置在出液腔208中,反弹弹簧302的一端与套筒腔203的内壁相连、另一端朝向动子4的对应端部悬空设置,使得动子4受磁驱力作用而移动时、与反弹弹簧302的悬空端接触,而被触发反弹作用;反弹弹簧302的劲度系数大于支撑弹簧301,用于对动子4施加反弹力,动子4靠近排液管204设置,即使动子4在靠近排液管204位置处振动,可以进一步提升排液管204的出液速度、出液量。
如图19和图20所示,为了提升动子4在套筒腔203内的平衡性,可以在出液腔208和进液腔207内分别设置支撑弹簧301,出液腔208和进液腔207内所设的支撑弹簧301分别将动子4的两端与出液腔208或进液腔207的内壁相连,以实现对动子4两端分别进行轴向限位支撑的效果,进而保证动子4在振动过程中不会产生偏移。
如图21所示,还有,为了节约成本,可以仅在出液腔208、或进液腔207内设置支撑弹簧301,依然可以保证动子4在套筒腔203内收磁驱力和弹力作用而振动的效果。
如图20所示,当然,为了节约成本,还可以将反弹弹簧302取消,而仅利用支撑弹簧301的弹性作用力为动子4提供复位弹力,同样可以实现驱动动子4在腔室内振动的效果。
如图24和图25所示,为进一步提升出液速度、出液量,提高出液效率,动子4上设有连通进液腔207和出液腔208的液体导流通道2031。
液体导流通道2031设置在动子4的内部、和/或动子4的外周面上,液体导流通道沿动子4轴向贯穿动子4,液体导流通道2031的形状包括直线状、弯曲状和螺旋状,液体导流通道2031设置一条或多条。
套筒腔203中的洗涤液,穿过液体导流通道2031,由进液腔207流动至出液腔208。优选的,液体导流通道2031的横截面积沿进液腔207至出液腔208的方向逐渐减小,或者,液体导流通道2031上设有单向导通结构,并且单向导通结构的导通方向为由进液腔207指向出液腔208。
通过液体导流通道2031,可以使洗涤液在动子4往复振动的过程中,不断地由进液腔207进入到出液腔208中,促进出液,通过液体导流通道2031上的单向导通结构,可以使液体导流通道2031中的洗涤液,由进液腔207至出液腔208单向流动,可增加出液腔208的液体压力,进而促进出液。通过改变液体导流通道2031的横截面积,可利于向洗涤液由进液腔207向出液腔208流动,增加出液腔208的液体,同样,具有促进排液的效果。
如图24所示,液体导流通道2031上所设的单向导通结构可以为单向阀206;也可以,如图25所示,液体导流通道2031上所设的单向导通结构为,液体导流通道2031为自与出液腔208相连通一端向与进液腔207相连通一端逐渐收窄孔径的锥形管;当然,还可以为其他的现有技术中的任一可实现单向导通的连通结构。
优选的,出液腔208的容积小于进液腔207的容积,由于动子4靠近排液管204设置,导致出液腔208的容积较小,通过缩小出液腔208的容积,可以使出液腔208内各处的洗涤液更加靠近动子4,可以使出液腔208内各处的洗涤液获得较大的振幅,利于出液。
本发明中,当动子4靠近进液腔207设置,动子4的端部突出于线圈501的端部设置时,动子4的中心向右侧偏离线圈501的中心偏心设置,出液腔208的容积大于进液腔207的容积,使动子4向左有更大的行程。
优选的,出液腔208具有变形部,该变形部靠近排液管204设置,并且,变形部沿指向排液管204的方向横截面积逐渐变小。通过变形部使出液腔208沿着指向排液管204的方向,横截面积逐渐减小,可进一步提升,出液腔208的出液压力,利于出液。
优选的,动子4具有与套筒腔203轴线垂直的前端面、后端面,前端面位于进液腔207中,并正对吸液管603,后端面位于出液腔208中,并正对排液管204。动子4的前端面上设有呈圆弧形的凸部,凸部朝向动子4的外部凸出,后端面上设置有呈圆弧形的凹部,凹部朝向动子4的内部凹陷。
动子4在振动过程中,动子4前端面上的凸部可起到导流的作用,进液腔207中的洗涤液沿着凸部表面流向出液腔208,动子4后端面上的凹部对洗涤液有一定的汇聚效果,通过该凹部可以对出液腔208内的洗涤液具有较好的挤压出液效果,促进出液。
本发明,通过线圈501、弹性元件3使动子4在套筒腔203中往复振动,通过动子4带动洗涤液波动,实现进液、出液。区别于现有技术中通过活塞、泵结构实现进液、出液,本
发明,动子4的外周与套筒腔203的内壁之间形成可供洗涤液通过的导流通道,一方面可使洗涤液沿套筒腔203的周向移动,实现进液、出液,另一方面,导流通道使动子4与套筒腔203的内壁相隔离,避免动子4动作时,与套筒腔203的内壁发生摩擦,避免动子4磨损,不会因为动子4磨损影响进液、出液效果,有效提高了使用寿命,适于长时间使用。
动子通过弹性元件3和线圈501实现往复振动,结构简单,无需设置活塞等气密性结构,有效降低了成本,经济性好。
