摘要： A dishwasher includes a housing having a washing chamber and a door for gaining access to the washing chamber. A washing nozzle is provided in the washing chamber for directing a fluid stream against dishes held in the washing chamber. A circulation pump circulates fluid under pressure through the washing nozzle. A supply line delivers fluid to the circulation pump while a drain line discharges fluid from the washing chamber. Additionally the dishwasher includes an acoustical insulation blanket of thermoplastic material. That blanket extends around the washing chamber and the circulation pump and is precisely cut to fit snugly around the fluid supply line and the drain line so as to eliminate gaps therebetween and the acoustical leaks associated therewith. A method is also disclosed for enclosing the noise-generating components of the dishwasher in an acoustical insulation blanket of thermoplastic material.
