The magnetic core a corresponds to the surface of the stator magnetic phantom 5, and has a _ sub-magnetic (hereinafter referred to as magnet 3 〇), and the magnetic core 34 corresponds to the outer side of the stator core 25, and has an outer rotor magnet. 3 is referred to as "magnet 33". β_ is composed of a thermosetting resin or the like, and the mounting hub 37 is molded by a rotating center portion. When the rotor 5b is cut, the frame 31, the core 32, and the magnet 30 are included, and the frame 31, the core 32, and the magnet 30 are molded by the die 36 to form the inner rotor 5b. Further, the outer rotor 5 runs with the frame %, the magnetic core is magnetized, and the frame 35, the magnetic core 34, and the magnet 33 are formed by molding to form the outer rotor 5a. Further, the rotor 5 series magnet 30 in Fig. 2 is incorporated in the magnetic core 32, and the magnetic core 34 has an IPM (internal permanent magnet) structure incorporated in the magnet 33. However, the rotor 5 is not limited to the rotor 5 of the PM structure. For example, it is also possible to have a magnet in which the magnet is fixed to the outer periphery of the magnetic anger 32, and the magnet 33 is fixed to the inner circumference of the magnetic core 34 by the SPM (surface permanent magnet). The '2' and the 'rotor 5' do not necessarily have the frame 31 and the frame 35. For example, the rotor 5 may also have one of the frame 31 and the frame 35, or neither. At this time, the rotor 5 can be molded into a magnetic core 32 having a built-in magnet 30 and a magnetic core 34 having a built-in magnet 33 by means of a mold 36, or the rotor 5 can be processed into a magnet 30 and a magnetic core by means of domain plastic molding. 32. Magnet 33 and magnetic core 34. 11 200813283 Since the stator coil 26 passes through a three-phase alternating current, a rotating magnetic field is generated in the stator 6. Due to the (four) magnetic field generated in the stator 6, the magnetic core 32 and the magnetic core 34 generate a rotational force. Further, the structure of Fig. 2 is formed by integrally molding the frame 31 and the frame 35 by the mold 36. However, the frame and the frame % are respectively composed of different individuals, and therefore, the molding process of the mold 36 having no configuration of the frame 31 or a configuration without the frame 35 can be performed. • Further, the mounting hub 37 is fixed to the rotating shaft 4, and the rotational force generated in the rotor 5 can be transmitted to the rotating drum 2. Thereby, the rotary drum 2 is rotatable. According to the above configuration, the drum type washing machine 50 can be provided with both the outer rotor 5a and the inner rotor 5b. In this way, since the characteristics of the motor 21 can be exhibited, the space utilization efficiency is high, that is, the space utilized is utilized to the maximum extent. Therefore, the motor torque generated per unit space of the motor 21 is increased. Therefore, the motor torque of the motor 21 is improved as compared with the motor of the same volume, or 15 is smaller than the motor having the same motor torque. It is known from the above that the washing capacity of the drum type washing machine 5G can be increased or the drum type washing machine 50 can be miniaturized. Further, the mold 23 includes a stator mounting leg 28 and a mounting hole 27 which are formed in a part of the mold 23 in an integrated state. Therefore, it is not necessary to attach the motor 21 to the special mounting member of the back surface 3b of the water tank 3. Moreover, the mounting of the motor 21 is also simple and can be carried out reliably. Further, the stator 6 is molded by an insulating material, and the back surface of the water tank 3 is attached to the mounting surface 22 on the surface side of the water tank 3 of the mold 23. Therefore, the stator 6 and the mounting member constituted by the die 23 are formed into a body. According to 12 200813283, by fixing the stator 6 to the back surface 3b of the water tank 3, the stator 6 can be easily attached to the back surface 3b. As a result, the drum type washing machine 5 can be easily assembled. (Implementation of sadness 2) ^ Fig. 3 is a schematic view of a drum type washing machine 50a according to a second embodiment of the present invention. Fig. 4 is a schematic cross-sectional view showing a drum type washing machine 50b according to another aspect of the second embodiment of the present invention. Further, Fig. 5 is a cross-sectional view of an essential part of the motor 21a used in the drum type washing machine 50a of Fig. 3. Fig. 6 is a cross-sectional view of an essential part of a motor 21b used in the drum type washing machine 50b of Fig. 4 . Further, as shown in Figs. 3 and 4, the drum type washing machines 5A, 50b 10 of the second embodiment are denoted by the same reference numerals as those of the first embodiment, and the detailed description thereof will be omitted. Further, the drum type washing machine 5A shown in Fig. 3 has a motor 2ia outer rotor type motor, and the drum type washing machine 5b shown in Fig. 4 has a motor 21b which is an inner rotor type motor. As shown in Figs. 3 and 5, the motor 15 21a used in the drum type washing machine 5〇a constitutes the rotor Φ 5 only by the outer rotor 5a provided outside the outer rotor space 15a, that is, when the motor 21a is composed, As shown in Fig. 5, the components which do not form the inner rotor 5b are used for assembly. Therefore, the motor 2ia has no inner rotor 5b. Further, as shown in Figs. 4 and 6, the motor 21b used in the drum type washing machine 5〇b constitutes the rotor 5 only by the inner rotor 5b provided in the inner rotor space 丨5b, that is, the motor 21b is composed of At this time, as shown in Fig. 6, the components which do not form the outer rotor 5a are used for assembly. Therefore, the motor 21b does not have the outer rotor 5a. Further, To represents the torque generated by the motor 2ia shown in Figs. 3 and 5, and the torque generated by the motor 21b shown in Figs. 4 and 6 is indicated by Ti. When the stator 6 has a common specification, the inner diameter Do of the outer rotor 5a is larger than the inner diameter Di (Do > Di) of the inner rotor 5b. Therefore, the torque generated by the motor 21a is large — the torque Ti generated by the motor 21b, that is, To>Ti. Further, as shown in Fig. 1, the torque T generated by the motor 21 having the outer rotor 5a and the inner rotor 5b is the torque To generated by the outer rotor 5a and the torque generated by the inner rotor 5b. The sum (To+Ti). That is, the torque T generated by the motor 21, that is, T = To + Ti. • As described above, the torque relationship generated by the motors 21, 21a, and 21b is established. In other words, one of the outer rotor motor 5a and the inner rotor motor 5b can be attached to the motor 21b shown in Fig. 4 and the motor 21a shown in Fig. 3, respectively, by the structure of the motor 21 shown in Fig. 1. In other words, the stator 6 constitutes a common member, and the motors 21, 21a, and 21b that realize the three types of motor torque specifications can be easily obtained in accordance with the required motor torque specifications. 15 The motor torque specifications of the required motors 21, 21a, and 21b are different depending on the specifications of the drum type washing machine 50, 50a, and 50b depending on the difference in the capacity of the rotary drum 2 or the difference in the amount of water used. However, the motors 21, 2, 211, and the drum type washing machines 50, 50a, 50b of the present invention can easily realize three kinds of motor rotations by using the same stator 6 and the outer rotor 5a or the inner rotor 5b. Moment specifications. • The thickness of the outer rotor 5a and the inner rotor 5b are not necessarily the same. The inner diameter and thickness of the outer rotor and the outer diameter and the outer diameter of the inner rotor can be appropriately selected according to the required three types of motor torque specifications. thick. As described above, the motor 21, 21a, 21b of the present invention uses the stator 6 as a member for a total of 14 200813283. Therefore, the production equipment for manufacturing the components of the motors 21, 21a, 21b can be implemented by switching a single device. Therefore, the productivity of the motors 21, 21a, 21b is not lowered. Further, regarding the assembly procedure of the outer rotor 5a and the inner rotor % of the rotor 5, it is possible to determine the necessity of assembly, and to change a part of the group 5 step ' or omit it. As described above, when the production method and the production equipment are changed to a minimum, the motors 21, 21a, and 21b having a plurality of types of motor torque specifications can be realized. As a result, the burden of the cost of the production equipment can be reduced, and the product can be highly productive. Therefore, it is possible to provide a drum type washing machine 50, 50a, 50b which is low in cost. As described above, the rotor 5 of the drum type washing machines 50, 50a, 50b of the present invention can utilize the ineffective space which has not been contributed to the torque of the motor in the past. Therefore, the torque of the motors 21, 21a, 21b can be increased and miniaturized. Moreover, the production equipment of the motors 21, 21a, and 21b can be shared and the productivity can be improved, and the motors 21, 21a, 21b and the 15 barrel type washing machines 50, 5A, 50b having different specifications can be easily realized. Low cost, high capacity and miniaturization.
