PREPARATION METHOD OF INTEGRAL DRAIN PIPE FOR POP-UP TYPE OPENING/CLOSING DEVICE OF SINK

摘要

The present invention relates to a manufacturing method for an integrated drain pipe for a pop-up type opening and closing device of a sink, and an integrated drain pipe for a pop-up type opening and closing device of a sink, manufactured by the same. Specifically, the present invention relates to a technique of integrally manufacturing a drain pipe without separately manufacturing the drain pipe in two parts of an accommodation pipe and a connection pipe of a pop-up type opening and closing device. According to the present invention, the integrated drain pipe for a pop-up type opening and closing device of a sink can simplify a manufacturing process by being integrally manufactured as not requiring middle connection, wherein the drain pipe discharges water of the sink by being applied to a drain of the sink. Therefore, the integrated drain pipe for a pop-up type opening and closing device of a sink can remarkably reduce manufacturing costs and manufacturing time of the drain pipe and can be conveniently assembled when applied to the sink. Also the integrated drain pipe for a pop-up type opening and closing device of a sink is integrally manufactured and prevents a leakage.
