Abstract
In the present invention, the disturbing noise of the operating pump created due to the periodic unstable rhythm of the discharge pump when the water level in the tub decreases during the evacuation of the washing machines, is eliminated by providing the cycling of the remaining small amount of water in the machine by means of a by-pass hose (1) placed between the discharge pump and the discharge hose (6).
Claims8
A washing machine comprising a tub, a discharge hose having an inner diameter, a discharge pump in communication with the tub and the discharge hose for pumping the water from the tub into the discharge hose, and a bypass hose having an inner diameter, said bypass hose lying in communication with one of the discharge pump and a water inlet hose from the tub connected to the pump and the discharge hose for cycling a small amount of water left inside the tub when the water level in the tub is low to suppress discharge pump noise, the ratio of the inner diameter of the bypass hose to the inner diameter of the discharge hose being greater than 0.25 and less than 0.70.
