具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本发明的技术方案主要应用在洗碗机等需要对大范围进行喷淋的设备中。以洗碗机为例，清洁水通过喷淋臂向各个方向进行喷淋。但是从固定的喷嘴中喷出的液体轨迹单一且固定，容易产生液体覆盖不到的死角。针对上述问题本申请对喷淋装置的结构进行了改进。
图1示出了根据本发明的喷淋装置的实施例一的局部结构示意图；图2示出了图1的喷淋装置的喷嘴的结构示意图。如图1、图2、图7和图8所示，实施例一的喷淋装置，包括本体1及设置在本体1上的喷嘴2，本体1上设置有安装孔，喷嘴2可转动地安装在安装孔中，喷嘴2上设置有出水孔20。喷嘴2被设置为当流体流经喷淋装置时，喷嘴2受到流体的作用而转动。
应用本实施例的技术方案，喷嘴上设置有出水孔，并且喷嘴可转动地安装在安装孔中。可转动的喷嘴能够增大喷淋覆盖面积，提高洗净性能。
具体地，喷嘴2上的出水孔20的轴线与喷嘴2的旋转基面之间的夹角大于0度并小于90度。上述结构使从喷嘴2中喷出的液体会随喷嘴的转动向四周喷淋，增大了洗涤范围。此处的旋转基面是指一个垂直于喷嘴旋转轴线的平面，喷嘴转动时喷嘴上各点至该旋转基面的距离不变，仅改变相位角。
进一步地，喷嘴2包括基体10和喷液管40。喷液管40设置在基体10的外表面上，出水孔20设置在基体10上，喷液管40与出水孔20相通，喷液管40的轴线与喷嘴2的旋转基面之间成预设角度。根据需要计算设计预设角度，进而改变喷嘴2的转速和喷淋范围，控制洗涤效果。
进一步地，图3示出了图2的喷嘴的仰视示意图。如图2和图3所示，在本实施例中， 喷嘴2上的出水孔20为一个。一个出水孔20使喷嘴2喷出的水压比较大、水流比较快。
如图2和图3所示，在本实施例中，出水孔20偏离基体10的中心线设置。上述结构使从喷嘴喷出的水流可以随喷嘴的旋转向四周喷射，也就是说，当喷嘴旋转时，从喷嘴喷出的水流的方向可以跟着改变，增大了喷嘴喷出的水流的覆盖范围。
另外，在本实施例中，如图1所示，喷嘴包括基体10及设置在基体10的外表面上的喷液管40，喷液管40设置在出水孔20处，喷液管40的轴线与基体10的外表面成预设角度。喷液管40增加了液体在喷出前的作用距离，并且对喷嘴喷出的液体进行导向。上述结构保证了喷出液体的压力和角度，进而保证了喷出液体的轨迹和覆盖范围。
同时，具有一定压力的液体在喷出喷液管40时，也会对喷嘴的基体10产生反作用力，使喷嘴旋转。
进一步地，如图2和图3所示，喷嘴还包括设置在基体10的内表面上的第一导流叶片51，第一导流叶片51位于出水孔20的周向外侧。第一导流叶片51在受到液体的冲击时，在作用力的作用下带动基体10旋转，进而带动流出出水孔20的液体旋转，保证了液体基本能够达到喷嘴覆盖范围内的所有位置。
为了进一步增强液体冲击第一导流叶片51的效果，保证喷嘴旋转流畅，在本实施例中，如图2和图3所示，喷嘴还包括设置在基体10的内表面上的第二导流叶片52，第二导流叶片52包括沿出水孔20的周向延伸的第一导流部，第二导流叶片52与第一导流叶片51的内端相连接，上述内端是指第二导流叶片52朝向出水孔20的一端。第一导流部沿出水孔20的周向延伸，阻挡一部分出水孔20的边缘，使液体更集中地流向第一导流叶片51或者出水孔20，提高喷嘴旋转的流畅度。
进一步地，在本实施例中，如图2和图3所示，第二导流叶片52还包括连接在第一导流部远离第一导流叶片51的第二导流部，第二导流部相对于第一导流部弯折或者弯曲设置。上述结构进一步地区分了喷嘴中流向第一导流叶片51和出水孔20的液体，避免在喷嘴旋转过程中，流向第一导流叶片51的液体和流向出水孔20的液体相互干扰，进而避免两股流体相互干扰削弱喷嘴旋转的流畅度和喷出液体的压力。
具体地，如图2和图3所示，在本实施例中，第二导流叶片52的中部与第一导流叶片51相连接。第一导流叶片51连接在第二导流叶片52的中部使喷嘴的结构对称，容易实现、易于生产，并且效果稳定。
上述的喷嘴利用液体的推力和液体喷出时的反作用力进行旋转，不需另外提供动力，节约能源。
如图2所示，喷嘴还包括安装部30，安装部30设置在基体10的内表面上，安装部30具有防脱结构，防脱结构用以防止喷嘴从安装孔中脱出。
基体上设置有出水孔，基体通过安装部固定在喷淋装置的安装孔中。安装部具有能够防止基体从安装孔脱出的防脱结构，进而有效地防止了喷嘴的脱落，保证了喷嘴的工作稳定性。
上文对本实施例的喷嘴的功能结构进行了详细的描述，下面对本实施例的喷嘴的装配结构进行说明。如图1和图2所示，在本实施例中，安装部30包括安装柱31，防脱结构为设置在安装柱31的自由端的钩体。在喷嘴安装在喷淋装置的安装孔上时，钩体通过安装孔勾住喷淋装置的内壁，可以有效地防止喷嘴脱落。上述结构简单，容易实现、易于生产并且效果明显。
安装部30限制了喷嘴安装后在安装孔中的轴向活动。在本实施例中，为防止喷嘴安装后在安装孔中的径向活动，如图1至3所示，安装部30还包括设置在内表面上的限位部32。限位部32在喷嘴装配完成时可以抵接在安装孔的内壁，或者与安装孔的内壁仅保留较小的装配间隙。上述限位部32用于防止基体10相对安装孔产生径向位移。
具体地，如图1至图3所示，本实施例的限位部32为限位柱。限位柱和安装柱31间形成间隙，保证液体可以顺利通过并流向出水孔20，减少液体在流动过程中的能量损失，保证了液体在流出喷液管40时的液体压力。
在其他实施例中，根据液体流向的不同以及喷淋装置结构的不同，限位部32也可以是限位环或者不完整的限位环。
图4示出了根据本发明的喷嘴的实施例二的结构示意图。如图4所示，实施例二的喷嘴改变了出水孔20的位置、去掉了第一导流叶片51和第二导流叶片52并用限位环取代了实施例一中的限位柱。
图5示出了图4的喷嘴的俯视示意图；图6示出了图4的喷嘴的仰视示意图。如图5和6所示，在实施例二中，出水孔20偏离喷嘴2的旋转轴线设置，且出水孔20的轴线在喷嘴2的旋转基面上的投影不经过旋转轴线。上述结构实现了当流体流经喷淋装置时，喷嘴2受到流体的反作用力而转动。具体地，出水孔20的位置相较于实施例一更靠近基体10的边缘，并且喷液管40的轴线更接近基体10的切线方向。上述结构使实施例二的喷嘴可以更好地利用液体喷出喷液管40时的反作用力进行旋转，也因此省去了第一导流叶片51和第二导流叶片52，进一步简化了喷嘴的结构。
限位环使喷嘴在安装孔中的受力更加均匀，同时，环状的限位部32可以使液体更集中地流向出水孔20，增加喷出喷液管40液体的压力。
上文对本申请的喷嘴的两种实施例进行了详细地描述，根据本申请的另一方面，还提供了一种喷淋装置。
图7示出了根据本发明的喷淋装置的实施例一的结构示意图，如图7所示，本实施例的喷淋装置包括可转动地本体1及喷嘴2，本体1上设置有安装孔，喷嘴2安装在安装孔中，喷嘴2可以为上文中描述两种喷嘴。上述本体1为喷淋臂。本实施例的喷淋装置的喷嘴2在随喷淋装置进行旋转的同时绕自身轴线进行自转，减少了喷淋盲区，并且具有结构简单并且安装牢固不容易脱落的优点。在本实施例中，同时采用了两种形式的喷嘴，采用了两个实施例二的喷嘴和一个实施例一的喷嘴，两个实施例二的喷嘴设置在本体的枢转轴的一侧。
进一步地，图8示出了图7的喷淋装置的内部结构示意图。如图8所示，本体1内部设 置有与安装孔连通的流道，本体1内部还设置导液板60，导液板60的第一端连接在流道的侧壁上，导液板60的第二端朝向喷嘴2的中心线延伸。导液板60使液体在从本体1中心流向本体1两端时，会更集中地流向喷嘴2，增加喷出液体的压力。对于实施例一的喷嘴而言，上述结构实现了液体对第一导流叶片51和第二导流叶片52的稳定冲击。对于实施例二的喷嘴而言，上述结构使液体更集中的流向出水孔20，提高了清洗效果。
进一步地，在本实施例中，安装孔为多个，多个安装孔中至少部分安装孔与本体1的枢转轴线的距离不相等。
另外，本申请还提供一种洗碗机(图中未示出)，包括喷淋装置，喷淋装置为上文描述的喷淋装置。具有结构稳定，使用寿命长的优点。并且喷淋装置的喷淋范围大、轨迹复杂，洗净性能强。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：
喷嘴上设置有出水孔，并且喷嘴可转动地安装在安装孔中。可转动的喷嘴能够增大喷淋覆盖面积，提高洗净性能。
