Drain hose for electrical appliance having water outlet

摘要

A continuous drain hose (100) for an electrical appliance (10) having a water outlet (30) is disclosed. The drain hose comprises a first cylindrical end portion being connectable to the water outlet (30), a second end portion being connectable to a drain pipe (40) and comprising a bellows (110,120,130) that is able to form a permanent bend when a temporary bending force is applied thereto, and a flexible corrugated portion (210,220) connected between the first cylindrical end portion and the second end portion. The bellows is also permanently expandable or retractable when a temporary pulling or pressing force is applied thereto. The drain hose (100) further comprises an elastic connection member, which is integrally molded to the first cylindrical end portion and is sealably connectable to the water outlet (30). The first cylindrical end portion comprises at least one annular ring externally formed thereon so as to prevent the molded elastic connection member from being disengaged from the first cylindrical end portion.
