Claims14
A drum type washing machine, comprising;
- A cabinet;
- A tub provided in the cabinet;
- A drum rotatably provided in the tub;
- A motor to rotate the drum;
- An integral bearing housing assembly, including;
- A hub configured to receive a rotational shaft of the drum therethrough and bearings positioned at a central portion thereof;
- A supporting portion that extends radially outward from an outer circumference of the hub, wherein the motor is mounted on the supporting portion;
- and
- A coupling portion that extends radially outward from the supporting portion;
- A first bracket attached to the coupling portion of the bearing housing assembly and extending outward in a radial direction with respect to the rotational shaft;
- A second bracket coupled to the coupling portion of the bearing housing assembly and extending outward in a radial direction with respect to the rotational shaft, wherein the first and second brackets are symmetrically positioned with respect to the rotational shaft;
- and
- First and second dampers respectively coupled to the first and second brackets so as to reduce the vibration of the drum.
