现代家用电器的自动化程度越来越高,形形色色的传感器充当了自动化控制的媒介,给现代家用电器披上了神秘的面纱.本文以全自动洗衣机水位开关为切入点,介绍了其结构及水位自动控制原理,目的是想通过这一案例,引导学生认识自动控制的基础仍来源于我们所学知识,并非高深莫测.通过自制洗衣机模型,既能培养学生的动手动脑能力,又能较好地提升学生的科学素养.
Modern household appliances more and more high degree of automation, sensors of all kinds act as a medium of automatic control, to the mysterious veil of modern household appliances.In this paper, automatic washing machine water level switch as the starting point, introduced its structure and automatic water level Control principle, the purpose is to pass this case, to guide students to understand the basis of automatic control is still derived from the knowledge we have learned, not unpredictable.By making a model of the washing machine, not only to develop students’ hands-on brain ability, but also better Enhance students’ scientific literacy.
