发明名称 Drain standpipe
摘要 A washing machine standpipe that has a drainage outlet in Lifting on an inner tube inside the standpipe uncovers a lower opening on the standpipe, allowing trapped water to escape. When the lower opening is in a closed position by having the inner tube cover it, water exits into the standpipe from the top portion as is conventional. The inner tube can be automatically lifted and the lower opening uncovered upon the completion of a machine cycle.
