ABSTRACT:
A drain system is presented for conveying a liquid (e.g., water) exiting an end of a drain line. The drain line may be, for example, mechanically coupled to a drum of a washing machine, and may undergo limited movement during operation of the washing machine. The drain system includes a conduit and a splash plate, and provides mechanical isolation between the moveable drain line and the fixed conduit. The splash plate allows limited relative movement between the drain line and the conduit while providing a substantially splash proof connection between the drain line and the conduit. The drain system is suitable for use within a semiconductor fabrication clean room. The conduit has an axis substantially aligned with an axis of the drain line, and has an end with an opening larger than an outer dimension of the drain line. A lip surrounds the opening in the end of the conduit. The splash plate has a substantially planar bottom surface and a hole extending through splash plate and dimensioned to receive the drain line. The end of the drain line extends through the hole in the splash plate and into the conduit opening, and the bottom surface of the splash plate makes continuous contact with the conduit lip.
