Problems solved by technology

[0009] However, in the above-mentioned conventional structure, the method of driving by two motors requires a space for its arrangement, and the overall size of the equipment is particularly large in the height direction, and it is also a structure that is not conducive to cost reduction.
[0010] In addition, in the method of installing the motor on the back of the bucket, when expanding the model of the washing machine, when increasing the capacity of the rotating drum, at this time, when increasing the motor torque, if the thickness of the motor (stack thickness) Or increase the outer diameter to increase the torque, there is a proble

Example Embodiment

[0037] (Embodiment 1)

[0038] 1 is a schematic cross-sectional view of a front-loading washing machine according to a first embodiment of the present invention, and FIG. 2 is a main-part cross-sectional view of a motor of the front-loading washing machine.

[0039] In FIG. 1 , the same components as those shown in FIG. 5 or 6 of the conventional example will be described with the same reference numerals.

[0040] In Fig. 1, a drum type washing machine main body 1 has a built-in water tub 3 and a rotating drum 2 rotatably arranged in the water tub 3, and a rotating shaft 4 is provided at the center of rotation of the rotating drum 2 in a substantially inclined direction, so that the rotating drum The axial direction of 2 is inclined downward from the front side toward the back side, and the motor 21 is installed on the back side of the bucket 3, that is, the outer bottom surface 3b.

[0041] The stator 6 of the motor 21 is fixed on the bottom surface of the bucket 3 through t...

Example Embodiment

[0053] In the structure shown in FIG. 2 of this embodiment, the inner rotor frame 31 and the outer rotor frame 35 are integrally molded with the rotor resin molding 36 at the same time, but the inner rotor frame 31 and the outer rotor frame 35 are also molded together. Since it can be constructed separately, molding can be performed separately without the inner rotor frame 31 and without the outer rotor frame 35 , and this can be extended to Embodiment 2 described below.

[0054] The mounting sleeve 37 is fixed on the rotating shaft 4 in FIG. 1 and is used to rotate the rotating drum 2 .

[0055] According to the above structure, by arranging both the outer rotor and the inner rotor, the space usable as a motor can be utilized to the maximum. As a result, the torque generated per unit space increases, so that the motor torque can be increased or the motor can be reduced in size, thereby increasing the capacity and reducing the size of the front-loading washing machine.

Abstract

The invention provides a motor for washer and drum-type washing machine, in the rotaty motor of the drum-type washing machine, the motor is made large-torque and minitype, and through minimal production device and a great variety of torque specification required by switching corresponding device of production device, the cost is reduced. In motor of rotary roller (2) drived by connecting with the rotation axis(4) which can freely revolve and pivot, an outboard rotor (5a) and inboard rotor (5b) are respectively set on the outboard of the stator (6) and the inboard. Based on the required torque of the motor, any one or two of the outboard rotor (5a) and inboard rotor (5b) is used to correpond with multi device of different torque specification.

Description

technical field [0001] The invention relates to a drum-type washing machine that supports the rotating shaft horizontally or obliquely in a bucket, and uses a motor to drive the rotating drum to rotate to perform washing, rinsing, and dehydration processes, or to a drum-type washing machine that performs the various processes of washing, rinsing, dehydration, and drying. Washing and drying machines, and the motors used. Background technique [0002] Conventionally, in this type of drum type washing machine, as the structure of the motor for driving the rotation of the rotating drum, there are two motors, the first motor that can rotate forward and reverse during the washing process, and the second motor that performs the dehydration process. At the outer bottom of the bucket, a driving method in which the rotation is transmitted to the rotating drum through a V-shaped belt (for example, refer to Patent Document 1); , with reference to patent document 2); the motor installed...
