Description

Driving device for fully automatic washing machine {Driving device for washing machine}

The present invention relates to an outer rotor type BLDC motor of a washing machine, by forming a locking rib on the side wall of the rotor frame formed of a metal material so that the rotor frame can be used in common even if the size of the magnet is changed.

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.

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, resulting in a problem that the washing machine is overall long. That is, the washing machine is made as high as the length of the inner rotor type induction motor compared to the conventional washing machine, which does not correspond to the washing machine height determined by the height of the consumer.

When the inner rotor type induction motor is attached to the side of the clutch as described above, it is pointed out that the structure is complicated, the driving force is reduced, and the eccentricity of the washing tank is caused. And when the inner rotor type induction motor is attached to the lower end of the clutch has a disadvantage that the length of the washing machine should be long.

The present invention is to solve the above problems, the first object is to simplify the structure of the clutch, while obtaining a strong rotational force required for washing and a high rotational speed required for dehydration.

The second object of the present invention is to provide an automatic rotor washing machine which is convenient for use by consumers by preventing the eccentricity of the washing tank by applying the outer rotor type motor and reducing the height of the washing machine itself.

Inside the outer tub, a washing tank for both washing and dehydration is installed. The upper washing shaft 210 is installed in the washing tank, and the upper end of the upper washing shaft 210 is provided with a washing wing for rotating the laundry in the forward and reverse directions.

The dewatering shaft 100 for rotating the washing tub is directly connected to the washing tub, and the upper dehydrating shaft 120 for rotating the washing tub is connected to the upper dehydrating shaft 120, and a cylindrical drum having teeth formed on a lower inner circumferential surface thereof. 160, the lower dehydration shaft 140 is connected to the lower end of the drum 160 and transmits the rotational force of the motor to the upper dehydration shaft 120.

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. 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.

Therefore, in order to use the same rotor frame 510 regardless of the longitudinal length of the variable magnet 520, a plurality of locking ribs R are formed around the inner surface of the rotor frame 510.

The locking ribs R support the bottom surface of the magnet 520 when the magnet 520 is bonded around the inner surface of the rotor frame 510 in place of the step 530. Since the magnet 520 is supported by R), the same rotor frame 510 may be used in response to the vertical length change of the magnet 520.

The locking rib R cuts a part of the inner circumference of the rotor frame 510 and presses the lower side of the cutout from the outside to the inside. A cross section of the rotor frame 510 cut by the pressure as described above protrudes to the inside to form a locking rib (R). An upper end of the locking rib R may be horizontal to support a lower end surface of the magnet 520.
