Embodiment Construction

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] figure 2 A sectional view showing a structure of a washing machine according to an embodiment of the present invention having a rotor structure.

[0040] Such as figure 2 As shown, the water storage tank is arranged inside the main body of the washing machine, and a bearing housing 30 is fixed below the water storage tank. A bearing 32 is provided on the above-mentioned bearing housing 30, and the above-mentioned bearing 32 supports the dehydration shaft 70 which will be described below. The washing shaft 60 and the dehydration shaft 70 to be described below are provided concentrically through the bearing housing 30 .

[0041] The lower end of the bearing housing 30 is provided with a stator 40 constituting a driving force source for driving the washing machine. A stator coil 42 is wound around the outer periphery of the stator 40 . ...

Abstract

This invention relates to a rotor structure of a washing machine, in which, even if the height of the rotor is reduced, insulation can be carried out surely. In this invention, connectino to the rotor yoke formed by magnetic bodies and a drive part driven by a cleaning shaft is finished by rotor shaft sleeve formed by insulation materials which forms integrally on the driven part by a plug module, besides, since the drive part is formed by metal powder, the drive part can contact with the cleaning shaft directly to transfer the rotor power to the shaft.

Description

technical field [0001] The invention relates to a washing machine. More specifically, it relates to a rotor structure for generating driving force to start a washing machine. Background technique [0002] figure 1 A sectional view showing the internal structure of a prior art washing machine. Such as figure 1 As shown, the outer tank 3 is fixedly supported inside the outer box body 1 . The washing tank 5 is rotatably supported inside the outer tank 3, and the washing tank 5 is directly driven by a drive shaft 7, and the drive shaft 7 is rotated by a motor assembly 20 which will be described below. That is to say, the washing tub 5 is directly rotated by the rotation of the driving shaft 7, and the laundry in the washing tub 5 can be washed when the washing tub 5 is rotated in forward and reverse directions. [0003] In addition, the driving force for rotating the above-mentioned drive shaft 7 comes from the motor assembly 20 installed at the lower end of the above-menti...
