从流体力学观点看节水型座便器的优化设计

Considerations of Optimum Design on Water-saving Toliets from the Hydromechanical Perspective

本文从流体力学的观点出发,阐述了座便器冲洗排污原理,分析了影响冲洗排污效果的主要决定因素:冲洗水作用水头。据此,进而分析了采用空气助压来充分利用自来水压能和利用人体自重对水箱冲洗水进行加压等节水措施,以及座便器的内防臭措施。

The text exactly proceeded from the hydromeehanical perspective, expounded the principles of toilet washing and blow- down , analyzed the main factors that influenced the effects of washing and blowdown： the water washing head. Accordingly, further analysised water--saving measures of using air pressure to help to make full use of water pressure and using the body weight to make pressure to the tanks of the washing water and other measures, and inner deodorant measures of the toilets.
