hub 311 may have a center opening 311a with a front bearing 21 and arear bearing 22 placed in opposite sides thereof for rotatably supporting the rotating shaft (see 40 inFIG. 2 ). - The supporting
portion 312 surrounds the outside circumference of thehub 311 and is extended in a radial direction therefrom. It is preferable that the supportingportion 312 has a thickness of, for an example, 2 ∼ 3 mm, and has a shape repeatedly projected and recessed substantially with reference to a plane perpendicular to an axis of thehub 311 along a circumferential direction. The projected portion of the supportingportion 312 may have the fasteningboss 312a for fastening thestator 51 of the motor as described before. - In the meantime, the
fastening portion 313 is an extension from thehub 311 longer than the supportingportion 312. It is preferable that thefastening portion 313 is fabricated of a stiff material thicker than the supportingportion 312. This is because theconnective supporter 400 is fastened to thesecond fastening boss 313a of thefastening portion 313 for supporting weight of thedrum 10 and the bearinghousing 300. - In the embodiment, a plurality of the
fastening portions 313 are formed in a radial direction of the bearinghousing 300, for an example, two as shown in the drawing. Theconnective supporter 400 is fastened to each of thesecond fastening bosses 313a of the fasteningportions 313.

Preferable, a plurality of theconnective supporters 400 are provided, and more preferably, theconnective supporters 400 are provided symmetrically under the bearinghousing 300. - As a result, the
extension portion 410, extended in the radial direction of the bearinghousing 300 from a lower side thereof, uniformly distributes force to theconnective supporter 400. Theconnection portion 420 transmits the distributed force from theextension portion 410 to thevibration attenuating device 60. In detail, theconnection portion 420 is mounted parallel to the bottom of thecabinet 70 substantially, and may be connected to a firstvibration attenuating device 61 having a damper and a secondvibration attenuating device 63 having a spring at an underside of theconnection portion 420. - The
extension portion 410 may have reinforcingribs 411 for reinforcing strength of theconnective supporter 400 for sustaining the force to theextension portion 410. - In the meantime, the
second bearing housing 320 is connected to thefirst bearing housing 310 on a front side of thefirst bearing housing 310, i.e., on a front side of the supportingportion 312. - The
first bearing housing 310 is injection molded inserted in thesecond bearing housing 320, or fabricated separately and coupled with thesecond bearing housing 320. In a case thefirst bearing housing 310 is injection molded inserted in thesecond bearing housing 320, thefirst bearing housing 310 and thesecond bearing housing 320 will be fabricated as one unit. In the meantime, thesecond bearing housing 320 may be formed of plastic, and thefirst bearing housing 310 may be formed of metal, for an example, aluminum. - In the meantime, since the
front bearing 21 and therear bearing 22 are placed in the same component ofhub 311, there is no axis misalignment between thefront bearing 21 and therear bearing 22. - Moreover, since only a component with heavy weight, i.e., only the
fastening portion 313 fastened to theconnective supporter 400 is fabricated of the stiff material, while the supportingportion 312 fastened to thesecond bearing housing 320 is fabricated of thin material, total weight and size can be reduced. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims.
- The drum type washing machine of the present invention has the following advantages.
- First, the bearing housing, having the supporting portion for mounting the stator of the motor thereto and the fastening portion for mounting the connective supporter thereto fabricated as one unit, permits to reduce a number of components, and a time period, required for assembly of the bearing housing.
- Second, while the related art vibration attenuation device supports the tub directly, because the connective supporter of the present invention extended in the radial direction of the bearing housing distributes force to the bearing housing, vibration noise from an entire system can be reduced.
- Third, the direct fastening of the stator of the motor and the connective supporter to the strong first bearing housing improves system stiffness, and makes an entire system lighter.
