摘要

In Japan, washing machine has become a necessity of life, and almost every household is equipped with one.However, in apartment buildings built before the 1970s, washing machines had been installed in a dressing room next to a bathroom, and an extended hose used for drainage through the bathroom because of the absence of drainage pipes for a washing machine in the building.But a sprawling pipe in the dressing room could be cumbersome, sometimes causing leakage.And it is difficult to install a pipe exclusively for drainage from a washing machine.Sphonic drainage system may hold a key to solve this dilemma as its use of pipes with small diameters, no slope or straddling has the advantage over the conventional drainage system.In this study we conducted experiments and analyzed flow characteristics in view to applying siphonic drainage system to washing machine drainage.We also examined how flow characteristics would be affected by detergent discharge and a self-sealing trap connected to prevent self-destruction.Siphon effects were observed under all experimental conditions.It also became clear that the use of self-sealing trap or detergent discharge had little influence on flow characteristics.
