産業上の利用分野
本発明は冷却用のファンを備えた電気洗濯機のモータに
関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a motor for an electric washing machine equipped with a cooling fan.
従来の技術
従来、電気洗濯機に使用するモールドモータは第４図、
第６図のような構造になっていた。Conventional technology Conventionally, the molded motor used in electric washing machines is as shown in Fig. 4.
The structure was as shown in Figure 6.

このシャフト６に冷却用のファン７を取り付けていた。That is, a coil is inserted into a slot provided in the core 1, placed in a mold, and covered with resin to form the motor body 2. At the time of this formation, the mounting hinge 3 for mounting the motor, which was made to protrude from the side surface of the motor body 2, was also integrally processed at the same time. 4 and 6 are bearing parts provided on the upper and lower sides of the motor body 1, with a shaft 6 protruding from the lower bearing part 5,
A cooling fan 7 was attached to this shaft 6.

有していた。Problems to be Solved by the Invention However, in such a structure, the motor main body 2 is fixed with the shaft 7 facing down below the tank 8 that stores water, and the fan 7 that blows air upward onto the shaft is installed. The configuration is such that the motor body 2 is cooled by attaching the hinge 3 to the side, but since the mounting hinge 3 protrudes to the side, the air from the fan 7 flows as shown by arrow a on the hinge side, and the air flows upward. Bearing 4
had the problem of not being effectively exposed to the wind. Therefore, if the temperature of the bearing is regulated by technical standards, such as in an electric washing machine, the temperature of the bearing does not meet the standard, so the temperature generated by the coil must be reduced to below the specified value, and the motor The problem was that the device itself was expensive.
本発明は上記課題に鑑み、モータの軸受の冷却効果を高
めることを目的とする。In view of the above problems, an object of the present invention is to improve the cooling effect of a motor bearing.

実施例
以下、本発明の一実施例の電気洗濯機のモールドモータ
について、第１図〜第３図を参照しながら説明する。Embodiment Hereinafter, a molded motor for an electric washing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

A letter-shaped rib 13 is provided. 14 and 15 are bearings,
16 is a shaft, and 17 is a cooling fan.

風を有効に軸受部１５に当てることができる。In general, molded motors cover the entire motor with highly conductive resin, so heat from the stator in the core section 6 is easily dissipated, but the rotor, which is located in the center of the stator, Therefore, the temperature of the bearing parts 14 and 15 tends to rise. However, regarding the 11 receiving part 14 on the shaft side, the shaft 1
There is a reed directly under the fan 17 attached to the fan 6 for effective cooling. By providing a guide rib 13 in the shape of a 7-shape with an acute angle on the shaft side for the bearing part 16 on the opposite side of the shaft, the air flow on the hinge 8 side also flows as shown by the arrow. It is possible to effectively send wind to 15. Furthermore, if the bottom surface shape of the tub 18 of the electric washing machine to which the motor body 11 is attached is configured to have an angle of around 46° with respect to the motor shaft so as to cover the opposite side of the motor body 11 from the shaft, the fan 17 can be The wind blown upward can be effectively applied to the bearing portion 15.
