1. A washing machine comprising:
a casing that defines an opening at a front surface of the casing;
a tub disposed in the casing to contain fluid, the tub having an opening that communicates with the opening of the casing;
a drum rotatably disposed in the tub;
a pump configured to transmit water discharged from the tub;
a gasket that extends between the opening of the casing and the opening of the tub, the gasket having an inner circumferential portion that defines a passage connecting the opening of the casing to the opening of the tub, the gasket having a first area disposed at one side in a width direction of the casing with respect to a vertical plane passing through a center of the drum;
a plurality of nozzles disposed in the inner circumferential portion of the gasket and configured to spray water into the drum, the plurality of nozzles including a plurality of first nozzles disposed in the first area of the gasket;
a nozzle water supply pipe that is fixed to the gasket and has an opening into which the water sent by the pump is introduced; and
a circulation pipe that connects the nozzle water supply pipe to the pump,
wherein the nozzle water supply pipe includes:
a circulation pipe connection port that connects the circulation pipe to the opening of the nozzle water supply pipe,
a transfer conduit that extends upwardly from the circulation pipe connection port, that is disposed around an outer circumferential portion of the gasket, and that has a curved shape extending along the outer circumferential portion of the gasket, the transfer conduit including (i) a first conduit that extends from the circulation pipe connection port in a first direction and is disposed in the first area of the gasket, and (ii) a second conduit that extends from the circulation pipe connection port in a second direction opposite to the first direction, and
a plurality of nozzle water supply ports that protrude from the transfer conduit toward the gasket, that are inserted into the gasket, and that are connected to the plurality of nozzles, the plurality of nozzle water supply ports including a plurality of first nozzle water supply ports that protrude from an inner surface of the first conduit and are connected to the plurality of first nozzles, the inner surface of the first conduit facing and extending along the outer circumferential portion of the gasket,
wherein the gasket further comprises a plurality of port insertion pipes that protrude from the outer circumferential portion of the gasket and that communicate with the plurality of nozzles, respectively,
wherein the plurality of nozzle water supply ports are inserted into the plurality of port insertion pipes, respectively,
wherein the transfer conduit comprises a plurality of uplift portions that are convex in a direction away from the outer circumferential portion of the gasket and that are disposed at positions corresponding to the plurality of port insertion pipes, respectively, and
wherein the plurality of nozzle water supply ports protrude from the plurality of uplift portions, respectively.
