摘要： A washing machine includes a casing, a tub, a drum, a circulation pump, an annular gasket connecting between openings of the casing and the tub and including circulation nozzles configured to supply water into the drum, and a conduit fixed to the gasket and guiding water to the circulation nozzles. The conduit includes an inlet port configured to receive water from the pump, a transport pipe configured to guide water from the inlet port to the circulation nozzles, and a supply ports configured to supply water to the circulation nozzles. A method for manufacturing a conduit includes positioning supply ports in a cavity defined at a first mold, forming a parison having a hollow opening by extruding a raw material, positioning the parison in the cavity, combining the first mold and a second mold, and injecting gas into the hollow opening of the parison.

摘要： A method of controlling a washing machine. The washing machine includes a tub with an entry hole configured to receive laundry, a drum rotatably disposed in the tub, a ring-shaped gasket disposed along a circumference of the entry hole of the tub, a pump configured to circulate water that is discharged from the tub, and at least one circulation nozzle provided in the gasket and configured to spray the water that is circulated by the pump into the drum. The method includes: supplying water into the tub; rotating the drum; accelerating a pump speed of the pump while the drum rotates; and based on the pump speed of the pump reaching a threshold speed during the acceleration of the pump, opening a spray valve of the washing machine such that water supplied from an external water source is sprayed into the drum through a direct water nozzle.
