Here, regarding the washing motor 9, FIGS.
The details will be explained with reference to the figures. In FIG. 1, 12 is a stator, and 13 and 14 are brackets attached to both upper and lower ends of the stator 12 in the figure. A rotor shaft 15 is rotatably supported by these brackets 13 and 14 via bearings (not shown). Here, the brackets 13 and 14 have a thickness of about 40 to 80 mm between two metal plates, e.g.
Vibration-damping steel plate 18 (trade name: “Pipeless”, manufactured by Nippon Steel Corporation), which is a plate material made by sandwiching μ viscoelastic resin 17
It is constructed by molding. A flange-shaped mounting plate portion 19 is integrally formed on the lower bracket 14.

Also, regarding the motor 10 for dewatering, the brackets 24 and 25 are made of vibration-damping steel plates 18, similar to the motor 9 for washing described above, and the mounting plate formed on the bracket 25 at the lower part in FIG. The plate portion 26 is connected to the motor support member 8

According to the above configuration, when the washing motor 9 is driven by executing the washing operation, vibrations generated by the motor 9 are transmitted from the stator 12 to the bracket 14. At this time, the bracket 14 is composed of a distributed steel plate 18, and this vibration damping steel plate 18 converts vibration energy into thermal energy by shear deformation A of the viscoelastic resin 17 accompanying bending vibration, as shown in FIG. This provides a vibration damping effect. Therefore, since the vibrations of the motor 9 are absorbed by the viscoelastic resin 17, transmission of the vibrations to the motor support member 8 can be prevented. Therefore, resonance 9 of the motor support member 8 can be prevented, and noise can be reduced. Moreover, in this case, since the brackets 13 and 14 are simply constructed from vibration-damping steel plates 18 instead of ordinary steel plates, complex vibration-proofing and sound-proofing structures can be easily constructed without the need to change the bracket mold. This can be realized with a configuration.

Furthermore, even in the case of dehydration operation, since the brackets 24 and 25 of the dehydration motor 10 are made of the split steel plate 18, noise can be reduced in the same manner as described above.

In the above embodiment, the present invention is applied to a two-tub type washing machine, but the present invention may also be applied to a dehydrating and dehydrating washing machine. In this case, the motor support member to which the motor for washing and dewatering is attached is the outer bottom of the water tank, and conventionally, vibrations generated by the motor are transmitted to the water tank and then further transmitted to the outer box via the hanging rod. There was a problem in that the outer box vibrated and generated a lot of noise. In contrast, in the present invention, the vibrations generated by the motor are absorbed by the bracket and are not transmitted to the water tank, so that noise can be reduced.

[Effects of the Invention] As is clear from the above description, the present invention relates to a washing or dehydrating motor attached to a motor support member,
Since the bracket of the motor is made of a plate material made by sandwiching a viscoelastic resin between two metal plates, it is possible to prevent vibrations generated by the motor from being transmitted to the motor support member, thereby reducing noise. Moreover, it has the excellent effect of being able to realize this with a simple configuration.
