Problems solved by technology

[0026] However, the prior art motor used in the washing machine has a problem that since the rotor 34 has a complicated structure in which the rotor magnet 42 and the magnet holding portion 40d are passed through the adhesive In combination, the rotor sleeve 44 is to be fixed on the sleeve holding portion 40a by a plurality of fastening members 46 etc., and the production of the prior art motor is difficult.
[0030]Moreover, like the rotor magnets of BLDC motors, outer rotor type magnetic induction motors also have the problem of complex structure and difficult manufacture, such as fixing the rotor core to the rotor frame inside is difficult

Abstract

The present invention relates to an outer rotor type magnetic induction motor (60) installed under an outer drum (54) of a washing machine, in which a rotor core (124) and a rotor sleeve (126) are inserted into a rotor frame (122) and are integrally Injection molding is used to simplify the structure of the rotor for easy manufacture of the rotor (120).

Description

technical field [0001] The present invention relates to a motor for a washing machine, and in particular, to an outer rotor type magnetic induction motor for a washing machine, which has a simple structure that is easy to manufacture. Background technique [0002] In general, a washing machine removes dirt from laundry and bedding (hereinafter referred to as laundry) held in a washing tub by using the shock of a water cycle and the chemical action of detergent. [0003] FIG. 1 shows a sectional view of a prior art washing machine, and FIG. 2 shows an exploded perspective view of the motor of FIG. 1. Referring to FIG. [0004] Referring to FIG. 1 , a washing machine of the related art is provided with a cabinet 2 forming its exterior; an outer tub 4 with a supporting member 4a suspended inside the cabinet 2, which has a space for holding washing water; an inner tub 8 rotatably mounted in the outer tub 4 , a commutator 6 is installed at the bottom, and water holes are arrange...
