Drum type washing machine

Abstract

Drum type washing machine including a tub of plastic having a wall for holding washing water therein and mounting a driving part thereon, a drum rotatably arranged inside of the tub, a shaft passed through the tub and connected to the drum for transmission of a driving power from a motor to the drum, at least one bearing for supporting the shaft, a bearing housing having a sleeve form of bearing supporting part, and a stator fastening part extended in a radial direction from the bearing supporting part, wherein both of the bearing supporting part and the stator fastening part are inserted in a tub rear wall, while stator fastening holes in the stator fastening part are exposed, a rotor engaged to a rear end part of the shaft to form the motor together with the stator, and the stator mounted on the stator fastening part of the bearing housing with fastening members on an inner side of the rotor to form the motor together with the rotor, wherein the stator includes an annular helical type core having multiple layers formed by winding a steel plate having tooth portions and a base part in a helix starting from a bottom layer to a top layer, an insulator having the helical type core encapsulated therein, a coil wound on the tooth portions, and fastening parts formed as a unit with the insulator, having fastening holes projected toward an inside of the helical type core for fastening the stator to the bearing housing, thereby reducing a weight of required material, simplifying an assembly process, and assure stable mounting of the stator on the tub.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200310117288.2 and the application name "drum type washing machine" submitted on December 10, 2003. [0002] This application claims the benefit of Korean Application No. P2002-0078337 filed on December 10, 2002 and Korean Application No. P2003-0086841 filed on December 2, 2003, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a drum type washing machine, and more particularly to an improved structure of a driving part of a direct drive type drum type washing machine using an outer rotor type brushless DC motor. Background technique [0004] In general, a drum type washing machine washes clothes using the frictional force between a drum rotated by a driving force of a motor and clothes (detergent, washing water, and clothes have been put in the drum), exhibiting little damage to clothes and no ...

AI Technical Summary

Problems solved by technology

[0023] Meanwhile, as time goes by, the capacity of the drum type washing machine tends to become larger and larger, which has caused many problems. In the case of more than 1.5kg, even the barrel to which the stator is fastened is damaged

[0024] Therefore, in order to prevent such damage from occurring, in prior art constructions, the metal tub support is usually produced in a production line, if in addition to the assembly line, a process for fastening the tub support to the rear wall of the tub is required, then Reduced productivity
