Description

一种射流器及投放装置及衣物处理设备 技术领域
本发明涉及衣物处理设备领域,尤其涉及一种应用于衣物处理设备供水水路上的射流器,还涉及一种具有向衣物处理设备进水功能的投放装置,特别涉及一种装有上述射流器的投放装置。
背景技术
随着经济水平的发展,越来越多的洗涤设备已经进入了用户的家庭;而随着生活水平的提高,洗涤设备不仅仅是单一的只具有洗涤功能,还集成具有了很多其他的功能,例如:烘干、熨烫等等。我们在此统称其为衣物处理设备。
但无论具有何种功能,一般衣物处理设备均需安装投放装置,以使得衣物处理设备利用投放装置上设置的不同供水水路,实现向衣物处理设备的不同用水部件进水的效果。同时,现有衣物处理设备的投放装置上设有供一种或多种添加剂进行投放的投放腔,使得投放腔内的添加剂可随投放装置上设置的不同供水水路进行相应投放,以实现衣物处理设备的不同衣物处理功能。
但是,现有的投放装置结构上存在如下问题:
衣物处理设备在进水过程中,如遇进水水龙头损坏、进水管脱落、用户家庭停水等等停水情况时,会在衣物处理设备的进水管处产生负压;尤其是,在用户小区停水时,用户所住楼层过高情况下,会使用户的自来水供水管路中产生负压,使得衣物处理设备的供水水路中混合有添加剂的水流反向倒流,进入自来水管,就会造成对用户家庭用水水源的污染。
而现有技术中,一般是在衣物处理设备的供水水路的进水口处加装单向止逆阀,以解决上述问题,但是单向止逆阀存在着失效的可能,令整个衣物处理设备的供水系统不可靠。
有鉴于此,为解决以上问题,特提出本发明。

具体实施方式
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,对实施例中的缺陷管理模式进行详细说明。
实施例一
如图1至图5所示,本实施例中介绍了一种射流器100,所述射流器100主要应用于洗衣机、干衣机等衣物处理设备进水使用,使得进水水流可经射流器进行加压、获取加大水压的进水水流,同时还能实现防止进水水流倒流、避免混合有添加剂的水流相互串水等情况的发生。
本实施例中,所述的衣物处理设备用的射流器100,由依次相连的前室部1、连接部2和后室部3构成供水流流经的通道。本实施例中,射流器的前室部1的两端分别为射流器的进水口4和射出孔8,进水口4用于与上游水道相连通、射出孔8与连接部2相连通;连接部2的两端分别与前室部1的射出孔8和后室部3的射入孔9相连通,同时连接部2上设有将射流器100构成的流道与外部大气相连通的间隙10,间隙10用于将自后室部3倒流的水流排出、以实现安装有射流器的水路防倒流的使用目的;后室部3的两端分别为射入孔9和射流器100的出水口5,射入孔9与连接部2相连通、并与射入孔9相对开设,使得射入孔9流入的连接部2中的水流可在自身水压的作用下跃迁过连接部2上所设间隙10、直接喷射至后室部3上的射出孔8中,以实现射流器100进水水流不受间隙干涉、顺畅进水的效果。
本实施例中,后室部3具有沿水流方向逐渐增大截面尺寸的变径流道,变径流道的小口端直接与射入孔9相连通,以使得后室部3的进水端由收窄的变径流道构成、进而减少后室部3中倒流水流的流量及压力,进而避免倒流水流跃迁过间隙10流入前室部1情况的发生;同时,由于将后室部3的射入孔9连通收窄的变径流道,使得后室部3与间隙10相连通处的孔径变小,令后室部3内的水流压力不会泄压、进而达到了对后室部3内水流进行保压的目的。
本实施例中,射流器100的射出孔8和射入孔9同轴设置,射出孔8喷射流出的水流经 连接部2构成的流道部分直接流至射入孔9内,以使得自射出孔8喷射出的水流可不受干涉的直接喷入射入孔9内,实现进水水流跃迁过间隙10、顺畅进水的使用效果。
本实施例中,射流器100的连接部为筒状结构,前室部1和后室部3分别处于筒状结构的连接部2的两端,前室部1的射出孔8和后室部3的射入孔9均与筒状结构的连接部2的轴线同轴、或平行设置;优选的,射入孔9和射出孔8靠近筒状连接部2的轴线处设置,以减小喷射的进水水流受筒状连接部2内壁干涉的影响。
本实施例中,为了保证水流跃迁效果、提升射流器100的保压功效,特进行如下设置:筒状连接部2的孔径大于射入孔9和射出孔8的孔径;优选的,筒状连接部2的孔径远大于射入孔9和射出孔8的孔径;进一步优选的,筒状连接部2的孔径大于射入孔9孔径的两倍、且同时大于射出孔8孔径的两倍,以实现后室部的进水端并非敞口开设、而使经敞口的变径流道与连接部相连通,进而达到对后室部内水流进行保压的效果。
如图1至图5所示,本实施例中,射流器100为壳体15构成的独立件,壳体15呈柱状,柱状壳体15内部中空构成轴线呈直线延伸的流道;流道内部设有间隔排布的两个分隔筋,分别为前端壁13和后端壁14,用于将壳体15内部的流道分为三部分;前端壁13和后端壁14之间的壳体15构成连接部2;壳体15两端的流道端部分别构成进水口4和出水口5,进水口4与前端壁13之间的流道部分构成前室部1,出水口5与后端壁14之间的流道部分构成后室部3;射出孔8设于前端壁13、射出孔8设于后端壁14,且射入孔9和射出孔8同轴并接近筒状壳体15的轴线方向设置;壳体15侧壁的中部开设有豁口,构成将连接部2与外部大气相连通的间隙10。
如图1至图5所示,本实施例中,后室部3上所设变径流道为沿射入孔9轴线方向延伸的第一锥形流道6,第一锥形流道6的小口端连接同轴等径设置的射入孔9、大口端连接处于后室部3远离连接部一侧的出水口5,出水口5用于连接射流器100下游的水路,第一锥形流道6与射入孔9同轴设置;优选的,第一锥形流道6的大口端的孔径大于射出孔8的孔径、小于等于筒状连接部2的孔径。
同时,本实施例中,虽然以变径流道设置为锥形为例进行展开描述,但本发明中的变径流道并不局限于锥形,还可以为仅一侧或多侧呈倾斜斜面的、截面面积沿进水水流方向增大的流道结构。
