Description

滚筒洗衣机及其喷淋系统 技术领域
本发明属于家用电器领域，具体提供一种滚筒洗衣机及其喷淋系统。
背景技术
现有滚筒洗衣机发源于欧洲，其由外至内主要包括箱体、外筒和内筒。滚筒洗衣机的工作方式与棒锤击打衣物原理类似。工作时，内筒在驱动电机的带动下转动。随着内筒的转动，衣物在滚筒中不断地被提升摔下，再提升再摔下，做重复运动。在洗衣粉和水的共同作用下，衣物被洗涤干净。
为了提高水流冲洗和漂洗衣物的效果，有的滚筒洗衣机还设置有循环喷淋装置。如公开号为CN102482834B的专利文献中公开的滚筒式洗衣机，其内设置有循环路径，该循环路径的一端通向水槽(外筒)的底端，该循环路径的另一端通向设置在水槽开口边缘的多个喷出口。循环路径能够从水槽的底端将洗涤水供给所述多个喷出口，进而喷进滚筒(内筒)中，对衣物进行循环冲洗。
虽然公开号为CN102482834B的专利文献中公开的滚筒式洗衣机对衣物的清洁能力较强，但是其设置有多个喷出口的水槽结构复杂，生产成本较高。
相应地，本领域需要一种新的滚筒洗衣机来解决上述问题。

此外，在保证内筒3内的衣物能够被喷淋的前提下，本领域技术人员可以根据需要，将喷嘴12的出水端设置成其他任意可行的形状，例如，蜂窝状、圆孔状、三角形状。
需要说明的是，本发明的排水泵6和/或循环泵8可以是任意可行的泵，例如、齿轮泵、叶片泵、蠕动泵、离心泵等。

综上所述，本发明的喷淋系统在保证内筒3中的衣物得到有效喷淋的情况下，把喷嘴12都设置在了密封窗垫5上，不仅安装结构方便，而且还使外筒2保持了原有结构，降低了滚筒洗衣机的生产成本。进一步，本发明还通过设置在循环泵8和多个喷嘴12之间的均压器10，将循环泵8泵送的洗涤水等压地分配给每一个喷嘴12，进而使所有的喷嘴12能够形成环形的水幕喷淋效果，使内筒3中的衣物得到更好的喷淋，优化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。
