Thus, when the user drives the washing machine after storing the laundry in the drum 4, first, the washing water is supplied to the tub 2 and the drum 4 by the water supply device 7, wherein the washing water is supplied with water. The washing water and the detergent are mixed and flow into the tub 2 while passing through the detergent container 7a installed in the apparatus 7.

Subsequently, when the supply of the washing water is completed, this is detected by the controller, and power is applied to the driving device 6 by an electrical signal transmitted from the controller, so that the washing operation is performed while the drum 4 is rotated.

After the washing operation is completed, a rinsing operation is performed, and after the rinsing operation is completed, a drainage operation is performed in which the washing water is discharged to the outside of the cabinet. In this case, the drum is rotated at a certain speed so that the laundry remaining in the laundry is discharged to the outside. do.

Bubbles are generated inside the drum and tub by the configuration and operation as described above. Since the drum washing machine uses less water than the pulsator washing machine, more bubbles are generated, and the rotating shaft of the drum is disposed in the horizontal direction. Since the resistance caused by foam also causes an overload, there is a problem that can cause malfunction and breakage of the washing machine.

The present invention has been made in order to solve the above problems of the prior art, by installing a chamber in which the foam is collected on one side of the tub, the foam generated during the washing operation is collected in the chamber and discharged to the outside of the cabinet along the drain pipe It is an object of the present invention to provide a defoamer of the washing machine.
