  • Patent number: 8113019
    Abstract: Disclosed is a drum type washing machine. The drum type washing machine includes a sealing member for preventing water between a tub and a drum from penetrating into a bearing for supporting a rotation shaft and a water penetration preventing unit for preventing the water between the tub and the drum from penetrating into the sealing member. Accordingly, it is doubly prevented that the water between the tub and the drum penetrates into the bearing, thereby preventing corrosion of the bearing due to the water. As a result, it is capable of preventing vibration and noise caused by the corrosion of the bearing and of stably supporting the rotation shaft with maintaining the initial performance of the bearing, thereby preventing the drum type washing machine from being out of order.
