摘　　要：提升洗净性能是洗碗机的重要研究方向之一,扇形喷嘴因为其覆盖面大、喷射均匀等优点在清洗行业应用广泛,因此提出将扇形喷嘴应用于洗碗机场景。利用CFD建立扇形喷嘴射流模型,对数值模拟结果进行分析,得出扇形喷嘴的射流特性,对比分析了圆形喷嘴和扇形喷嘴射流特性的优缺点。利用高速摄影技术,拍摄两种喷嘴的射流实况,最后通过分析洗净对比测试数据得到:扇形喷嘴喷臂洗净指数可达1.2,高于圆形喷嘴1.11。进而验证了扇形喷嘴对于洗碗机洗净效率的提升作用,为洗碗机喷臂优化提供方向。Cleaning capability is an important research direction of dishwasher.Fan nozzles are widely used in cleaning industry because of its large coverage and uniform injection,so it is proposed to apply fan nozzles in dishwasher scenarios.The jet model of fan-shaped nozzle is established by computational fluid dynamics(CFD),the numerical simulation results are analyzed,and the jet characteristics of the fan-shaped nozzle are obtained.The advantages and disadvantages of the circular nozzle and the fan-shaped nozzle jet characteristics are compared and analyzed.High-speed photography technology was used to photograph the actual jetflow of two nozzles.Finally,by analyzing and comparing the cleaning test data,it was found that the cleaning index of the fan-shaped nozzle spray arm can reach 1.2,which is 1.11 higher than that of the circular nozzle.Further verify the improvement effect of the fan-shaped nozzle on the cleaning effciency of the dishwasher,and provide direction for the optimization of the dishwasher spray arm.
