The present invention relates to a washing machine, and more particularly, to a noise filter mounting structure of a washing machine.

In general, a washing machine is a device for removing contaminants from clothes by using a detergent and water, and mainly a washing machine, a rinse, and a dehydration process are performed using an electric motor as a main power source.

On the other hand, the washing machine is divided into a drum type (cylinder type), an agitator type (agitator type), a pulsator type according to the washing method.

In detail, the drum type washing machine has a plurality of protrusions formed on an inner surface of the drum, and the protrusions cause the laundry contained in the drum to rise and fall when the drum is rotated at a low speed on the horizontal axis. At this time, an impact is generated, and washing is performed by the impact.

In addition, the stirring washing machine rotates the wing-shaped stirrer which protrudes in the center of the washing tank left and right to perform washing.

In addition, the spiral winding washing machine is to perform the washing by the water generated by rotating the pulsator forming the disk shape.                         

1 is a perspective view showing a conventional washing machine.
