Washing machine with circulating water supply pipe and manufacturing method of circulating water supply pipe

A washing machine comprising:

• a casing that defines a laundry inlet at a front surface;
• a tub that is disposed in the casing and that defines a tub opening at a front surface of the tub;
• a drum rotatably disposed in the tub;
• a pump configured to pump water discharged from the tub;
• a gasket that defines a passage that connects the laundry inlet to the tub opening;
• a plurality of nozzles disposed on an inner peripheral surface of the gasket and configured to inject water pumped by the pump into the drum;
• and
• a circulating water supply pipe that is disposed on an outer peripheral surface of the gasket opposite to the inner peripheral surface, the circulating water supply pipe being configured to guide the water from the pump to the plurality of nozzles,
• wherein the circulating water supply pipe comprises:
• an inlet port configured to receive the water from the pump,
• a feeding conduit made of a first material and configured to guide the water received through the inlet port toward the plurality of nozzles, and
• a plurality of discharge ports that protrude from the feeding conduit toward the gasket and that are configured to supply the water guided along the feeding conduit to the plurality of nozzles, and
• wherein at least one of the feeding conduit or each of the plurality of discharge ports comprises:
• a discharge flow path surface that defines a discharge flow path that is in communication with one of the plurality of nozzles, and
• a parting line that is disposed on the discharge flow path surface and that is made of the first material.
