Description

喷嘴、波轮洗衣机及其喷淋系统和外桶盖 技术领域
本发明属于喷淋设备领域，具体提供一种喷嘴、波轮洗衣机及其喷淋系统和外桶盖。
背景技术
波轮洗衣机主要包括箱体、外桶、内桶和波轮。其中，外桶固定地设置在箱体中，内桶可转动的设置在外桶中，波轮可转动的设置在外桶底部。在波轮洗衣机执行洗涤、漂洗作业时，波轮驱动外桶中的洗涤水和衣物转动，以达到清洗衣物的目的。在波轮洗衣机执行甩干作业时，内桶带动其内的衣物高速转动，使衣物上的水分在离心力的作用脱离衣物。
波轮洗衣机在使用的过程中经常会存在下列问题：其一，洗衣粉、洗衣液沉积在外桶的底部，不容易被洗涤水溶解；其二，洗涤的衣物较多时，容易出现部分衣物未被洗涤水浸润的情况；其三，羽绒等衣物在洗涤时经常漂在洗涤水液面以上，洗涤效果较差。
为了解决上述问题，现有的波轮洗衣机通常在外桶盖上设置喷淋装置。例如公告号为CN204282066U的专利文献中公开了一种波轮洗衣机，该波轮洗衣机的外桶盖上设置有多个喷嘴。在波轮洗衣机工作时，循环水泵能够将外桶中的洗涤水泵送给所述多个喷嘴，使多个喷嘴将洗涤水喷淋到内桶中的衣物上。但是该喷嘴上板状的挡水板打散洗涤水的效果较差，不能使洗涤水均匀地喷射到内桶中衣物上。
相应地，本领域需要一种新的喷嘴、波轮洗衣机及其喷淋系统和外桶盖来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有的波轮洗衣机对待洗衣物喷淋效果较差的问题。
本发明的技术方案1提供了一种喷嘴，所述喷嘴包括喷嘴本体和挡水结构，所述喷嘴本体内形成有喷射通道，所述挡水结构设置在所述喷嘴本体的一端并能够遮挡所述喷射通道，所述挡水结构面向所述喷嘴本体的一侧设置有凹部，所述凹部设置成使得从所述喷射通道喷出的液体能够被所述凹部打散并反射进目标对象中。
在上述喷嘴的优选技术方案中，所述凹部是具有弧形表面的凹部。
在上述喷嘴的优选技术方案中，所述挡水结构对应的两个侧边缘与所述喷嘴本体的所述一端之间的距离不同。
在上述喷嘴的优选技术方案中，所述挡水结构是勺形结构。
在另一方面，本发明的技术方案1还提供了一种波轮洗衣机的喷淋系统，所述波轮洗衣机包括箱体、固定地设置在所述箱体中的外桶和可转动的设置在所述外桶中的内桶，所述喷淋系统包括供水装置和多个上述优选技术方案任一项所述的喷嘴，所述目标对象是所述内桶；多个所述喷嘴分别设置在所述外桶的顶部，并且每一个所述喷嘴的喷射通道都与所述供水装置连通；工作时，所述供水装置将洗涤水提供给多个所述喷嘴，所述洗涤水冲击所述凹部之后被打散反射进所述内桶中。
在上述喷淋系统的优选技术方案中，所述波轮洗衣机还包括设置在所述外桶顶部的外桶盖，所述多个喷嘴与所述外桶盖固定连接或一体制成；并且/或者，所述喷嘴沿所述外桶的周向等间距设置。
在上述喷淋系统的优选技术方案中，所述喷淋系统还包括设置在所述外桶盖上的环形腔，所述环形腔与所述供水装置和所述多个喷嘴的喷射通道分别连通。
在上述喷淋系统的优选技术方案中，所述供水装置是循环泵，所述循环泵的进水泵口与所述外桶的内腔连通，所述循环泵的出水泵口与所述环形腔连通；或者，所述供水装置是进水阀，所述进水阀的进水阀口通向外界，所述进水阀的出水阀口与所述环形腔连通。

本领域技术人员能够理解的是，在本发明的优选技术方案中，挡水结构面向喷嘴本体的一侧设置有凹部，从喷射通道喷射出的洗涤水能够进入该凹部内。束状的洗涤水进入凹部后会沿着凹部的表面流动并延展开来，使洗涤水均匀地流出凹部，进而流出挡水结构，流进内桶中，对内桶中的衣物进行均匀地喷淋。因此，本发明的喷嘴能够提高波轮洗衣机对内桶中衣物的喷淋效果，进而优化波轮洗衣机对衣物的洗涤效果。
进一步，本发明的凹部为弧形的凹部。本领域技术人员能够理解的是，弧形的内凹面结构与平面结构相比，能够有效地避免洗涤水冲撞时的反射效果，防止洗涤水提早离开挡水结构，使洗涤水在挡水结构上延展的面积更大。因此，洗涤水经过弧形的凹部时能够被均匀地展开，进而能够均匀地落入波轮洗衣机的内桶中。
本发明的技术方案2提供了一种喷嘴，所述喷嘴包括喷嘴本体和与所述喷嘴本体固定连接或一体制成的挡水结构；所述喷嘴本体上沿轴向设置有喷射通道，所述喷射通道的一端通向水源，所述喷射通道的另一端被所述挡水结构封闭；所述喷嘴本体的侧壁上设置有与所述喷射通道连通的喷射口。

在上述喷淋系统的优选技术方案中，所述供水装置是循环泵，所述循环泵的进水泵口与所述外桶的内腔连通，所述循环泵的出水泵口与多个所述喷嘴的喷射通道分别连通；或者，所述供水装置是进水阀，所述进水阀的进水阀口通向水源，所述进水阀的出水阀口与多个所述喷嘴的喷射通道分别连通；并且/或者，所述喷嘴沿所述外桶的周向等间距设置。
除此之外，本发明的技术方案2还提供了一种波轮洗衣机的外桶盖，所述外桶盖包括盖体、设置在所述盖体上的环形腔和多个上述喷嘴优选实施方案中任一项所述的喷嘴，多个所述喷嘴的喷射通道的所述一端分别与所述环形腔连通，所述环形腔上设置有通向水源的进水口。
进一步，本发明的技术方案2还提供了一种波轮洗衣机，其特征在于，所述波轮洗衣机包括上述优选实施方案中任一项所述的喷淋系统。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过在喷嘴本体上设置喷射通道，通过挡水结构封闭喷射通道的一端，并在喷嘴本体的侧壁上设置与所述喷射通道连通的条形喷射口，使得本发明的喷嘴在被提供洗涤水时，能够使洗涤水沿着狭长的条形喷射口喷出，散射成瀑布状的水流。因此，当本发明的喷嘴应用到波轮洗衣机上时，喷嘴能够将循环泵供给的洗涤水完全地散射进内桶中，均匀地喷淋内桶中的衣物。
优选地，所述条形喷射口呈螺旋状的盘绕地形成在喷嘴本体的侧壁上，并且条形喷射口盘绕的圈数为半圈。喷嘴喷出的洗涤水也会因条形喷射口的形状而呈现出螺旋的瀑布状，螺旋的瀑布状的水流在落入内桶中时，能够对内桶中的衣物进行立体地、全方位地喷淋。因此，本发明的喷嘴能够提高波轮洗衣机对内桶中衣物的喷淋效果，进而优化波轮洗衣机对衣物的洗涤效果。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
技术方案1：
如图1和图2所示，本发明的波轮洗衣机主要包括箱体1、外桶2、内桶3、波轮4、驱动电机5、排水阀6和排水管7。其中，外桶2固定地设置在箱体1的内部，内桶3可转动的设置在外桶2中，波轮4可转动的设置在内桶3的底部。驱动电机5固定地安装到箱体1或外桶2上，驱动电机5通过转轴与内桶3和波轮4分别驱动连接。驱动电机5能够选择性地驱动内通3和波轮4转动。由于驱动电机5选择性地驱动内通3和波轮4的技术手段是本领域技术人员所熟知的技术手段，所以此处不再做过多说明。进一步，排水阀6的进水阀口通过水管与外桶2的内腔连通，排水阀6的出水阀口通过排水管7通向箱体1外。当外桶2内的洗涤水需要排出时，排水阀6被打开，洗涤水从排水管7排向外界。
优选地，外桶2上与排水阀6连通的排水口位于外桶2的底部，以便外桶2中的洗涤水能够通过该排水口拍净。进一步优选地，排水阀6被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将排水阀6安装到外桶2的外壁上。此外，本领域技术人员还可以根据 需要，省去排水阀6和外桶2之间的水管，使排水阀6直接安装到外桶2上，并与外桶2的内腔连通。
如图2所示，本发明的箱体1的顶部安装有盘座11，盘座11枢转地连接有门盖12。外桶2的顶部设置有外桶盖21，外桶盖21用于遮挡内桶3的上边缘，防止衣物进入外桶2和内桶3之间的夹层中。
如图3至图6所示，外桶盖21主要包括盖体211、环形腔212和进水口213，其中，环形腔212和进水口213都设置在盖体211上。本领域技术人员能够理解的是，盖体211既可以是一体制成的结构，也可以是由多个分体结构安装而成。示例性地，盖体211包括上盖体和下盖体，上盖体和下盖体中的至少一个上设置有环形槽。当上盖体和下盖体安装到一起时，上盖体和下盖体将环形槽封闭成所述环形腔212。
如图2、图5和图6所示，本发明的波轮洗衣机还包括喷淋系统，该喷淋系统包括循环泵8、循环水管9、环形腔212、进水口213和多个喷嘴10。
如图2所示，循环泵8的进水泵口通过水管与外桶2的内腔连通，循环泵8的出水泵口通过循环水管9与外桶盖21上的进水口213连通。优选地，外桶2上与循环泵8连通的出水口位于外桶2的底部。进一步优选地，循环泵8被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将循环泵8安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去循环泵8和外桶2之间的水管，使循环泵8直接安装到外桶2上，并与外桶2的内腔连通。
如图5和6所示，多个喷嘴10沿外桶盖21的周向等间距地固定地连接到或者一体成型到盖体211上，并且每一个喷嘴10都分别与环形腔212连通。进一步，每一个喷嘴10的喷射口都指向内桶3。此外，本领域技术人员也可以根据需要，使多个喷嘴10非等间距地设置在盖体211上。
继续参阅图5和图6，外桶盖21的盖体211的内侧还设置有环形的遮挡结构2111，该遮挡结构2111用于遮挡喷嘴10，防止喷嘴10被用户观察到，以便优选外桶盖21的外观。
虽然图中并未示出，但是在本发明另一个可行的实施例中，本领域技术人员可以根据需要，将多个喷嘴10直接地固定到外桶2的顶部，然后使循环水管9直接地或者借助其它水管与每一个喷嘴10连通。
如图2所示，循环泵8工作时能够将外桶2中的洗涤水吸出，并通过循环水管9泵送给外桶盖21上的环形腔212，进而使喷嘴10将洗涤水喷向内桶3中，对内桶3中的衣物进行喷淋。
此外，虽然图中并未示出，但是在本发明喷淋系统另一个可行的实施例中，本领域技术人员也可以根据需要，使外桶盖21上的进水口213通过水管与波轮洗衣机的进水阀连通。当进水阀的进水阀口与水龙头接通时，自来水能够沿着进水阀、水管和进水口213的路径提供给环形腔212，进而使喷嘴10将自来水喷射到内桶3中的衣物上，湿润衣物。
进一步，本领域技术人员也可以根据需要，使本发明的喷淋系统同时具有上述的循环泵8、循环水管9、进水阀以及连通进水阀和进水口213的水管，并且在进水阀和进水口213串联一个截止阀。此时，循环泵8和进水阀可以分别或共同作为供水设备。当需要自来水喷淋衣物时，进水阀和截止阀被打开。当需要外桶2中的洗涤水喷淋衣物时，循环泵8工作。
下面参照图7至图15来对本发明的喷嘴10进行详细说明。其中，图7至图12是本发明喷嘴10的第一实施例，图13至图15是本发明喷嘴10的第二实施例。
如图7至图10所示，在本发明的第一实施例中，喷嘴10包括喷嘴本体101和挡水结构102。其中，喷嘴本体101和挡水结构102可以采用任意可行的连接方式固定到一起，例如焊接、熔接、粘接等。或者，本领域技术人员也可以根据需要，使喷嘴本体101和挡水结构102一体制成。
如图8和图10所示，喷嘴本体101内设置有喷射通道1011。当喷嘴10安装到外桶盖21上时，图10中喷射通道1011的下端与环形腔212连通。环形腔212中的洗涤水流经喷射通道1011之后从图10中喷射通道1011的上端喷向挡水结构102，挡水结构102将洗涤水打散并反射进内桶3中。本领域技术人员能够理解的是，喷嘴本体101可以是 任意可行的形状，例如，圆形管柱结构、方形管柱结构、锥形管柱结构等。
如图7至图10所示，挡水结构102沿喷嘴本体101的轴向遮挡喷射通道1011。挡水结构102面向喷嘴本体101的一侧设置有凹部1021。优选地，该凹部1021是具有弧形表面的凹部，即凹部1021的表面是弧形面。进一步优选地，挡水结构102整体上为勺形结构。此外本领域技术人员也可以根据需要，将挡水结构102设置成其它任意可行的结构，例如，具有凹面的板状结构或具有凹面的块状结构。
如图10所示，洗涤水从喷射通道1011喷出之后会呈束状地喷向凹部1021内。落入凹部1021内的洗涤水会从着落点沿着凹部1021的弧面延展开来，最后从凹部1021的边缘流出形成扇形的瀑布状水流(如图11和图12所示)落入内桶3中。
本领域技术人员能够理解的是，通过改变凹部1021中弧形凹面的角度，能够调整洗涤水喷出的形状。如图11所示凹部1021的凹面是均匀的球面；如图12所示凹部1021的凹面是左右对称非均匀的弧面，并且该凹面向对称轴收紧，以便使洗涤水比较集中，喷的尽量远些。
本领域技术人员还能够理解的是，在能够将喷射通道1011喷出的洗涤水打散的前提下，凹部1021除了是弧形的外，还可以是任意可行的形状，例如U形凹部或扩口凹部。
参照图11和图12可知，本发明第一实施例中的喷嘴10所喷出的洗涤水是水平喷出的，即被喷嘴10喷出的瀑布状的洗涤水在绕喷嘴本体1011轴线的方向(与喷嘴本体1011的外圆周同心)向上的高度相同。
如图13至图15所示，在本发明的第二实施例中，与第一实施例不同的是，挡水结构102对应的两个侧边缘的高度不同，以便使洗涤水被挡水结构102反射之后能够在绕喷嘴本体1011轴线的方向上形成高度差(如图2和图15所示)。
如图13和图14所示，挡水结构102的第一边缘的中点到达喷嘴本体101下端的高度是H1，挡水结构102的第二边缘的中点到达喷嘴本体101下端的高度是H2。从图13和图14中不难看出H1小于H2。
本领域技术人员能够理解的是，本发明第二实施例中的喷嘴10不仅能够将洗涤水呈扇形的喷进内桶3中，还能够使喷出的洗涤水在圆周方向上形成高度差，对浮出洗涤水液面的衣物进行立体喷淋。
综上所述，在本发明的优选技术方案中，通过在挡水结构102面向喷嘴本体101的一侧设置凹部1021，使得喷射通道1011喷出的束状洗涤水能够被凹部1021均匀地打散开并流进内桶3中，对内桶中3的衣物进行均匀地喷淋。因此，本发明的喷嘴10能够提高波轮洗衣机对内桶3中衣物的喷淋效果，进而优化波轮洗衣机对衣物的洗涤效果。
此外，为了避免外桶盖21的盖体211发生损坏时，环形腔212漏水的情况发生，本发明还提供了外桶盖21的下述实施方案。
作为本发明上述外桶盖21的优选实施方案的替代方案，环形腔212还可以被管道替代。该管道与盖体211固定连接，两者之间可以采用任意可行的连接方式连接到一起，例如卡接、螺钉连接、粘接、绑接等。与环形腔212相同的是，管道也通过循环水管9与循环泵8连通并且/或者通过水管与进水阀的出水阀口连通，并且管道还与多个喷嘴10分别连通。本领域技术人员能够理解的是，管道与多个喷嘴10之间可以采用任意可行的连接方式连接到一起，例如螺纹连接、熔接、卡接、插接等。或者本领域及也可以根据需要，使管道与多个喷嘴10一体制成。本领域技术人员还能够理解的是，在能够与所有的喷嘴10都连通的情况下，本实施方案中的管道既可以是首尾相接并连通的环形管道，也可以是首尾不能相接的管道。进一步，本实施方案中的管道既可以是柔性的管道，也可以是刚性的管道。
本领域技术人员能够理解的是，构造简单的管道的防水性要优于复杂的盖体211的防水性，因此能够有效避免外桶盖21漏水，腐蚀箱体1和外桶2之间的电子元件。同时，当管道发生损坏时，管道的更换成本也要小于整个外桶盖21的更换成本，降低了波轮洗衣机的维修成本。
技术方案2：
如图16和图17所示，本发明的波轮洗衣机主要包括箱体1、外桶2、内桶3、波轮4、驱动电机5、排水阀6和排水管7。其中，外桶2固定地设置在箱体1的内部，内桶3可转动的设置在外桶2中，波轮4 可转动的设置在内桶3的底部。驱动电机5固定地安装到箱体1或外桶2上，驱动电机5通过转轴与内桶3和波轮4分别驱动连接。驱动电机5能够选择性地驱动内通3和波轮4转动。由于驱动电机5选择性地驱动内通3和波轮4的技术手段是本领域技术人员所熟知的技术手段，所以此处不再做过多说明。进一步，排水阀6的进水阀口通过水管与外桶2的内腔连通，排水阀6的出水阀口通过排水管7通向箱体1外。当外桶2内的洗涤水需要排出时，排水阀6被打开，洗涤水从排水管7排向外界。
优选地，外桶2上与排水阀6连通的排水口位于外桶2的底部，以便外桶2中的洗涤水能够通过该排水口拍净。进一步优选地，排水阀6被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将排水阀6安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去排水阀6和外桶2之间的水管，使排水阀6直接安装到外桶2上，并与外桶2的内腔连通。
如图17所示，本发明的箱体1的顶部安装有盘座11，盘座11枢转地连接有门盖12。外桶2的顶部设置有外桶盖21，外桶盖21用于遮挡内桶3的上边缘，防止衣物进入外桶2和内桶3之间的夹层中。
如图18和图19所示，外桶盖21主要包括盖体211、环形腔212和进水口213，其中，环形腔212和进水口213都设置在盖体211上。本领域技术人员能够理解的是，盖体211既可以是一体制成的结构，也可以是由多个分体结构安装而成。示例性地，盖体211包括上盖体和下盖体，上盖体和下盖体中的至少一个上设置有环形槽。当上盖体和下盖体安装到一起时，上盖体和下盖体将环形槽封闭成所述环形腔212。
如图17和图18所示，本发明的波轮洗衣机还包括喷淋系统，该喷淋系统包括循环泵8、循环水管9、环形腔212、进水口213和多个喷嘴10。
如图17所示，循环泵8的进水泵口通过水管与外桶2的内腔连通，循环泵8的出水泵口通过循环水管9与外桶盖21上的进水口213连通。优选地，外桶2上与循环泵8连通的出水口位于外桶2的底部。进一步优选地，循环泵8被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将循环泵8安装到外桶2的外壁上。此外，本领域 技术人员还可以根据需要，省去循环泵8和外桶2之间的水管，使循环泵8直接安装到外桶2上，并与外桶2的内腔连通。
如图18所示，多个喷嘴10沿外桶盖21的周向等间距地固定地连接到或者一体成型到盖体211上，并且每一个喷嘴10都分别与环形腔212连通。进一步，每一个喷嘴10的喷射口都指向内桶3。此外，本领域技术人员也可以根据需要，使多个喷嘴10非等间距地设置在盖体211上。
如图18和图20所示，外桶盖21的盖体211的内侧还设置有环形的遮挡结构2111，该遮挡结构2111用于遮挡喷嘴10，防止喷嘴10被用户观察到，以便优选外桶盖21的外观。
虽然图中并未示出，但是在本发明另一个可行的实施例中，本领域技术人员可以根据需要，将多个喷嘴10直接地固定到外桶2的顶部，然后使循环水管9直接地或者借助其它水管与每一个喷嘴10连通。
如图17所示，循环泵8工作时能够将外桶2中的洗涤水吸出，并通过循环水管9泵送给外桶盖21上的环形腔212，进而使喷嘴10将洗涤水喷向内桶3中，对内桶3中的衣物进行喷淋。
此外，虽然图中并未示出，但是在本发明喷淋系统另一个可行的实施例中，本领域技术人员也可以根据需要，使外桶盖21上的进水口213通过水管与波轮洗衣机的进水阀连通。当进水阀的进水阀口与水龙头接通时，自来水能够沿着进水阀、水管和进水口213的路径提供给环形腔212，进而使喷嘴10将自来水喷射到内桶3中的衣物上，湿润衣物。
进一步，本领域技术人员也可以根据需要，使本发明的喷淋系统同时具有上述的循环泵8、循环水管9、进水阀以及连通进水阀和进水口213的水管，并且在进水阀和进水口213串联一个截止阀。此时，循环泵8和进水阀可以分别或共同作为供水设备。当需要自来水喷淋衣物时，进水阀和截止阀被打开。当需要外桶2中的洗涤水喷淋衣物时，循环泵8工作。
下面参照图21至图26来对本发明的喷嘴10进行详细说明。
如图21和图22所示，本发明的喷嘴10包括喷嘴本体101和挡水结构102。其中，喷嘴本体101和挡水结构102可以采用任意可行 的连接方式固定到一起，例如焊接、熔接、粘接等。或者，本领域技术人员也可以根据需要，使喷嘴本体101和挡水结构102一体制成。
如图21、图22和图26所示，喷嘴本体101内沿轴向设置有喷射通道1011，喷嘴本体101的侧壁上设置有条形喷射口1012。挡水结构102设置在喷嘴本体101的一端(如图26所示喷嘴本体101的上端)，并且挡水结构102将喷射通道1011的一端封闭。当喷嘴10安装到外桶盖21上时，图26中喷射通道1011的下端与环形腔212连通。环形腔212中的洗涤水流经喷射通道1011之后从条形喷射口1012喷出并落入内桶3中。本领域技术人员能够理解的是，喷嘴本体101可以是任意可行的形状，例如，圆形管柱结构、方形管柱结构、锥形管柱结构等。
虽然图中并未示出，但是在本发明的优选实施中，条形喷射口1012开口的喷淋方向(即条形喷射口1012两个侧壁的向外侧的延伸方向)偏向挡水结构102的一侧。以便从条形喷射口1012喷出的洗涤水能够如图27所示的偏向挡水结构102的一侧，使大部分的洗涤水能够直接落到内桶3靠近轴心的位置，对内桶3中的衣物进行有效地喷淋。
此外，本领域技术人员也可以根据需要，使条形喷射口1012两个侧壁的向外侧的延伸方向垂直于喷嘴本体1011的径向。
如图21、图23至图25所示，条形喷射口1012呈螺旋状的盘绕形成在喷嘴本体101的侧壁上，并且条形喷射口1012盘绕的圈数为半圈。以便从条形喷射口1012喷出的洗涤水能够如图28所示的，呈半圆的扇形喷淋，增大了洗涤水的喷淋范围，优化了波轮洗衣机的喷淋效果。
结合图27和图28所示的喷嘴10的喷淋效果示意图，本领域技术人员能够理解的是，从条形喷射口1012喷出的洗涤水是螺旋状的瀑布形水流。
此外，本领域技术人员也可以根据需要，使条形喷射口1012的盘绕圈数少于半圈，使其喷出的洗涤水如图29所示的，呈小于半圆的扇形喷淋。
进一步，本领域技术人员还可以根据需要，在喷嘴本体101上设置多个条形喷射口1012。优选地，多个条形喷射口1012平行设置。
虽然图中并使出，但是在本发明另一个可行的技术方案中，本领域技术人员可以根据需要，使条形喷射口1012延伸至挡水结构102上，并可选地将挡水结构102设置成向远离喷嘴本体101的一侧凸起的结构，例如将挡水结构102设置成倒扣的碗状结构或锥形结构。
此外，在本发明其它可行的实施例中，本领域技术人员可根据需要，使条形喷射口1012非螺旋状的盘绕地形成在喷嘴本体101上，例如，将条形喷射口1012设置成V形、M形、N形、Y形等。或者，本领域技术人员也可以根据需要，将条形喷射口1012设置成I形，并使条形喷射口1012沿着喷嘴本体101的轴线方向设置。或者，本领域技术人员还可以根据需要，将条形喷射口1012设置成其它任意可行的喷射口。例如将喷射口设置成多个依次排列的孔结构。优选地该多个孔结构等间距设置。本领域技术人员能够理解的是，该孔结构是圆形孔、矩形孔、方形孔、梅花形孔等。
需要说明的是，在本发明的优选实施方案中，条形喷射口1012是一条狭长的缝隙，本领域技术人员可根据实际需要来对该缝隙的宽度进行调节。
基于本发明的上述描述，本领域技术人员能够理解的是，通过在喷嘴10的喷嘴本体101上设置螺旋状的条形喷射口1012，使得喷嘴10能够喷出螺旋状的瀑布形水流，该瀑布形水流能够在内桶3的圆周方向上和径向上形成高度差，进而能够对内桶3中的衣物进行立体地、全方位地喷淋，优选了洗衣机的洗涤效果。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
