Abstract

A drum washing machine having a detergent supply device supplying water containing detergent to a washing tub is disclosed. The detergent supply device has simple structure, so it is easy to manufacture the drum washing machine and the cost is reduced. The detergent supply device is integrally formed with a door without being installed in front surface of upper part of the main part, so it has simple structure. The detergent supply device is provided with a discharge unit discharging detergent dissolved in the water to the washing tub when the level of the water supplied to the detergent supply device reaches a designated value. The discharge unit delays the discharge of the washing water supplied to the detergent supply device by a siphon, thus improving the solubility of the detergent.
