The present invention relates to a fully automatic washing machine, and a fan member is formed at the bottom of the rotor frame formed of a metal material to allow external air to flow into the frame during rotation of the rotor frame, thereby cooling the stator assembly and its driving apparatus. It is about.

 In general, the automatic washing machine is a product that removes contaminants such as clothing and bedding by using friction and impact of the water flow caused by the emulsification of the detergent and the rotation of the washing blade 30. The sensor detects the amount and type of laundry, automatically sets the washing method, and supplies water to the appropriate level according to the amount and type of laundry.

As described above, in the conventional fully automatic washing machine, as shown in FIG. 1, a dehydration tank combined laundry tank 20 having a plurality of dehydration holes is rotatably installed in the outer tank 10 installed in the outer case 1. In the lower center of the washing tub 20, the washing blade 30 is rotatably installed. In addition, a driving device including a clutch 40 and a motor 3 for rotating the washing tub 20 and the washing blade 30 is installed below the outer tub 10.

That is, a motor 3 is installed at one lower side of the outer tub 10, and a clutch 40 for intermittent rotational power of the motor 3 is installed at the side of the motor 3. Pulleys 3a and 40a are coupled to the lower end of the shaft of the motor 3 and the clutch 40, and a belt 5 is connected therebetween.

As shown in FIG. 2, a clutch pulley 40a is provided below the clutch 40, and the lower washing shaft 51 and the upper washing shaft 35 are sequentially disposed above the clutch pulley 40a. Is connected. And the drum 56 is fixed to the lower end of the dehydration shaft 25 is coupled to the lower portion of the washing tank (20). A lower dehydration shaft 57 is coupled to a lower portion of the drum 56, and a planetary gear 52, which is a power reduction means, is installed inside the drum 56.

And the lower end of the lower washing shaft 51 is in contact with the lower end of the washing shaft 51, the clutch spring 44 and the spring block 45 and the clutch spring 44 surrounding the spring block 45 to be described later A spring boss 43 is installed to adjust the diameter of the spring. In addition, a brake lever 41 having an operating lever 46 and an operating cam 42 is installed at an outer circumference of the spring boss 43.

The drive device configured as described above is operated as follows during washing and dehydration. First, during washing, the spring boss 43 is engaged with the actuating cam 42 that operates by operating the brake lever 41 to twist the end of the clutch spring 44 in a direction in which the diameter increases.

Accordingly, the clutch spring 44 having an increased diameter maintains the spaced apart from the outer circumferential surface of the spring block 45. In this state, the rotational force of the motor 3 is transmitted to the clutch pulley 40a and the lower washing shaft 51 by the belt 5. The transmission force is transmitted from the upper washing shaft (35) to the washing blade (30), the washing tank in the direction opposite to the rotation of the washing blade (30) while being decelerated by the carrier (59) at the same time as the rotation of the washing blade (30). Rotate (20).

In addition, when the brake lever 41 is pulled during dehydration, the diameter of the clutch spring 44 is reduced as the actuating cam 42 is separated from the gear of the spring boss 43. By the restoring force of the reduced diameter as described above, the clutch spring 44 can be engaged with the lower dehydration shaft 57 and the spring block 45 at the same time.

On the other hand, when the lower washing shaft 51 receives the power of the motor 3 rotates, the lower washing shaft 51 and the fixed spring block 45 rotates like the lower washing shaft 51. At this time, the clutch spring 44 engaging the spring block 45 and the lower dehydration shaft 57 is subjected to rotational force in the winding direction. The rotational force connects the spring block 45 and the lower dehydration shaft 57 with more powerful force. In addition, the drum 56 and the planetary gear 52 may be integrally rotated by the strong connection force.

Thus, during the dehydration, the washing tub 20 as well as the washing blade 30 are rotated at high speed in the same direction to advance dehydration.

However, the driving device as described above transmits the rotational force of the motor to the power transmission shaft by the belt, thereby reducing the power. In addition, since the structure of the clutch and the deceleration means is very complicated, the production is difficult and the productivity is lowered, which is a cause of failure. In addition, the problem that the eccentricity of the washing tank occurs by attaching the motor to the side of the clutch has been raised.

In order to solve the problem of the eccentricity of the washing tank has been developed a technology for attaching the inner rotor type induction motor attached to the side of the clutch to the lower end of the clutch. The problem that the washing tank is eccentric by attaching the motor to the lower end of the clutch as described above has been solved.

However, while the inner rotor type induction motor is installed at the lower end of the clutch, the length of the inner rotor type induction motor is added to the length of the clutch, thereby causing a problem in that the washing machine is generally long. That is, the washing machine is made as high as the length of the inner rotor type induction motor as compared to the conventional washing machine, which does not correspond to the washing machine height determined by the height of the consumer.

The upper end of the upper dehydration shaft 120 is coupled to the lower connection of the washing tub 20 to transmit the rotational force of the motor to the washing tub 20. For example, the upper portion of the upper dehydration shaft 120 is formed in an octagonal shape, it is possible to efficiently transmit the rotational force to the washing tank. The upper dehydration shaft 120, the drum 160, the lower dehydration shaft 140 is coupled to each other by interference fit.

In order to support the rotation of the upper dehydration shaft 120, an oilless bearing 180 is installed between the upper dehydration shaft 120 and the upper washing shaft 210. In addition, an outer peripheral protrusion 211 is formed on the upper washing shaft 210 so that the upper washing shaft 210 is fixed at a constant height, and the outer peripheral protrusion 211 is formed at an upper end of the oilless bearing 180. Is supported by.

The oilless bearing 180 has a structure in which oil is supplied to the outside when heat is generated in a portion in contact with the oilless bearing 180. That is, when the upper washing shaft 210 rotates in the upper dehydration shaft 120, if the heat generated in the oilless bearing 180 by friction, the oil in the oilless bearing 180, the upper washing shaft 210 and the upper Exit between the dehydration shaft 120 to maintain a smooth rotation.

In addition, a clutch housing 300 including an upper clutch housing 300a and a lower clutch housing 300b is disposed below the upper dehydration shaft 120 and outside the upper portion of the drum 160 and the lower dehydration shaft 140. Screwed together. The clutch housing 300 serves to protect the drum 160 and is coupled to the upper and lower dehydration shafts 120 and 140 through upper and lower bearings 330 and 340 to support the upper and lower dehydration shafts 120 and 140.

And, the clutch housing 300 is coupled to the bracket fixed inside the washing machine serves to fix the components inside the clutch housing 300.

5 is a partial cutaway perspective view of the rotor assembly according to the present invention.

The rotor assembly 500 is installed on the outer periphery of the stator assembly 400 to generate a rotational force due to an electrode difference from the stator assembly 400. The rotor assembly 500 includes a rotor frame 510 forming an appearance and a magnet 520 attached to sidewalls of the rotor frame 510.

The rotor frame 510 of the rotor assembly 500 is formed by pressing a steel plate. In addition, a stepped portion 530 is formed on the sidewall of the rotor frame 510 to support the lower end of the magnet 520. In addition, a washing shaft coupling part 550 to which the lower washing shaft 240 is coupled is formed at the center of the rotor frame 510. The lower washing shaft 240 is engaged with the washing shaft coupling part 550 to transfer the rotational force of the rotor assembly 500 to the washing tank.

By configuring the rotor frame 510 of the rotor assembly 500 as described above, the heat generated when the motor is driven can be smoothly conducted to the rotor frame 510. In addition, the rotor frame 510 replaces the rotor frame 510 and the magnet 520 with a role of a back yoke to form a magnetic path, thereby reducing manufacturing processes and components.

And the upper end of the washing shaft coupling portion 550 is provided with a coupling member 550a formed separately from the rotor frame 510. The engagement member 550a may be formed by injection molding or die casting. In addition, the coupling member 550a may be selectively engaged with a sliding coupler 650 to be described later.

In addition, a plurality of fan members P is formed at the bottom of the rotor frame 510 to more smoothly perform heat dissipation of heat generated in the stator assembly 400. The fan member P bends the rotor frame 510 to face the upper side of the rotor assembly 500 by lancing. And as the fan member (P) is formed, the cooling hole (P1) according to the configuration of the fan member (P) is formed. The fan member (P) is formed of six sets of three, two of the three is bent in the direction in which the washing tank rotates during the dehydration stroke, the other one is bent in the opposite direction.

The fan member (P) is bent after the lancing processing different from each other as described above looks at the reason.

First, as described above, the rotor frame 510 is lancing to form the fan member P. At this time, if the lancing in one direction only, the phenomenon that the rotor frame 510 slides finely in the pressing direction occurs.

If the rotor frame 510 slides as described above, the position of the lancing is not accurate, and thus the size of the fan member P is not precisely molded. And the rotor assembly 500 is rotated in an eccentric form due to the dimensional deformation of the fan member (P).

The second reason is that the external air is supplied to the fan member P via the cooling hole P1 by the rotation of the rote assembly 500 to cool the heat generated in the stator assembly 400. The stator assembly 400 generates excessive heat during dehydration operation. Therefore, when the washing tank rotates in the dehydration direction, a lot of external air is required, and for this reason, it is necessary to form the fan member P that is bent in the rotation direction when dewatering.

In addition, since the rotor assembly 500 rotates left and right in the washing stroke, when the fan members P are bent to face each other, the supply of air by the fan members P can be more efficient. .

For these two reasons, it is advantageous that the fan member P is formed in different directions than is formed in only one direction. That is, when the lancing the bottom of the rotor assembly 500, the size of the fan member (P) is precisely molded, and the stator assembly 400 can be cooled more efficiently when the rotor assembly 500 is rotated forward and backward.
