Embodiment Construction

[0037] Next, an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 5 .

[0038] 2 is a cross-sectional view showing a mounting structure of a double rotor type motor according to an embodiment of the present invention. 3 is an exploded perspective view showing a double-rotor type motor according to an embodiment of the present invention.

[0039]As shown in FIGS. 2 and 3 , the above-mentioned double-rotor motor is composed of an outer rotor 10 , an inner rotor 20 and a stator 30 . A stator 30 is inserted between the outer rotor 10 and the inner rotor 20, and an upper portion of the stator 30 is fixed to the rear of the tub of the washing machine.

[0040] In detail, the upper part of the stator 30 is fixed on one side of the bearing housing, and the bearing housing is installed behind the stator; the lower part of the stator is inserted between the outer rotor 10 and the inner rotor 20 . At this time, the outer peripheral surface and...

Abstract

This invention provides one washing machine in which one dual-rotor motors is installed effectively. It includes: barrels used for containing wash water has the rotary drum in the inner side; dual-rotor includes external rotor with magnet supported by the inner surface and the internal rotor, which is installed in the medial external rotor, with magnet by the outer surface; bearing shell includes one bushings department which is installed at the back of the barrel used to support the rotation axis connected with the above mentioned dual-rotor; cover department which is formed integrally with the barrel by injection molding cover the outside of the bearing shell; the components of stator are as follows: the core at which sides correspond with the magnets of the external and internal rotors; the coil winded in the outside of the core; Department of mold, which is exposed in the two sides of the core, is formed outside of the core and coil by the method of injection molding; the fixed department, which is fixed in the bushings department mentioned above, is formed from the extension of above mold department.

Description

technical field [0001] The present invention relates to a washing machine; more particularly, the present invention relates to a washing machine equipped with a double rotor type motor. Background technique [0002] Generally speaking, the working process of the washing machine is as follows: When detergent, washing water and laundry are put into the drum, the drum is rotated by the driving force of the motor, and the friction between the washing water and the laundry is used to clean the drum. washing. Here, the above-mentioned drum generally refers to a washing tank for storing washing water and laundry, and it is applicable regardless of the drum washing method or the agitating washing method. [0003] In addition, the driving methods of the above-mentioned washing machine can be divided into the following types: the indirect connection method in which the driving force of the motor is indirectly transmitted to the drum through the belt wound around the motor pulley and ...
