Problems solved by technology

[0005] However, in the motor described in Patent Document 2, since the coil is wound in a concentrated winding method, the radial force becomes large.
As a result, there is a problem of increased vibration and noise during driving
[0006] In this way, the front-loading washing machine equipped with the washing machine motor described in Patent Document 1 and Patent Document 2 has the problem that it is difficult to achieve large capacity, small size, and quietness at the same time.

Embodiment Construction

[0060] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a cross-sectional view of the front-loading-type washing machine according to the embodiment of the present invention.

[0061] Bottomed cylindrical tub 3 is disposed in washing machine casing 1 of the front-loading washing machine in a state inclined downward from the front side of main body 1 toward the back side. The tub 3 rotatably supports a bottomed cylindrical rotary drum 2 inside the tub 3 such that the drum rotating shaft 4 is inclined downward from the front side toward the back side of the washing machine casing 1 .

[0062] An opening 1a for taking out and putting in laundry is formed on the front side of the washing machine casing 1 . On the opening portion 1a, a cover 9 made of a material such as glass for opening and closing the opening portion 1a is provided.

[0063] On the outside of the bottom of tub 3 , motor shaft 61 of motor 5 is dir...

Abstract

Provided is a drum type direct-drive washing machine comprising a washing machine casing, a rotary drum having a drum rotating axis in a horizontal direction or an inclined direction, and a motor fordriving the rotary drum. The motor includes a stator having a coil wound in a toroidal winding form and a first mold resin, and a twin type rotor having an external rotor, an internal rotor and a second mold resin molding the rotors integrally.

Description

technical field [0001] The present invention relates to a direct drive type drum-type washing machine including a rotating drum having a rotation center axis in a horizontal direction or an oblique direction, and a motor driving the rotating drum. Background technique [0002] In recent years, direct-drive front-loading washing machines with a drying function added to fully automatic washing machines have become mainstream. Because the motor that drives the rotating drum of the washing machine does not directly drive the rotating drum through a transmission device, it is necessary to simultaneously realize low speed and high torque (10rpm to 100rpm, 10N·m or more) during washing and high speed and low torque during dehydration ( above 1000rpm). In addition, since the washing speed is very low, it is necessary to reduce the cogging torque of the motor that greatly affects the vibration and noise of the washing machine. [0003] Motors for washing machines described in Paten...
