Washing machine with conduit for supplying water to nozzles at gasket and manufacturing method of the conduit

A washing machine, comprising:

• a casing that defines an introduction hole;
• a tub that is disposed in the casing and defines an entrance opening configured to communicate with the introduction hole;
• a drum rotatably disposed in the tub;
• a pump configured to pump water discharged from the tub;
• a gasket that has an annular shape and that connects between the introduction hole and the entrance opening;
• a plurality of circulation nozzles disposed at the gasket and configured to supply water into the drum;
• and
• a conduit fixed to the gasket and configured to guide water pumped by the pump to the plurality of circulation nozzles,
• wherein the conduit comprises:
• an inlet port configured to receive water pumped by the pump,
• a transport pipe that extends from the inlet port and is configured to guide water received through the inlet port to the plurality of circulation nozzles, and
• a plurality of nozzle water supply ports configured to supply water guided along the transport pipe to the plurality of circulation nozzles,
• wherein the transport pipe comprises:
• an inner diameter part that faces an outer circumferential surface of the gasket,
• a plurality of communication holes that are defined at the inner diameter part of the transport pipe and in fluid communication with the plurality of nozzle water supply ports, respectively, and
• a plurality of port connection grooves defined at positions corresponding to the plurality of communication holes, each of the plurality of port connection grooves being disposed at a circumference of one of the plurality of communication holes and receiving an entrance portion of one of the plurality of nozzle water supply ports,
• wherein the entrance portion of each of the plurality of nozzle water supply ports defines a port opening configured to receive water discharged from a corresponding communication hole among the plurality of communication holes,
• wherein the entrance portion of each of the plurality of nozzle water supply ports comprises a flange that extends outward in a radial direction of the port opening and is bonded to an inside of a corresponding port connection groove among the plurality of port connection grooves, and
• wherein an outer surface of the flange comprises:
• a first surface that extends outward in the radial direction of the port opening and is bonded to a floor of the corresponding port connection groove,
• a second surface spaced apart from the first surface to thereby define a thickness of the flange, the second surface being exposed to an outside of the corresponding port connection groove, and
• a conical slope that extends from the second surface and is inclined toward the first surface, the conical slope being bonded to the inside of the corresponding port connection groove.
