The present disclosure relates to a laundry dryer. The laundry treating apparatus includes a water supply connector for connecting an internal water supply pipe, a direct water pipe, and a water supply inlet pipe with each other. The water supply connector may include a connector main body and a connector backflow-preventing valve that is coupled into the connector main body to prevent water from flowing back toward an supply assembly, thereby preventing the water from flowing back to a water source and improving assembleability by mounting a check valve by only assembling a connector with a pipe.
