Description

Fully automatic washing machine {Washing machine}

The present invention relates to a fully automatic washing machine, and more particularly, to a method for controlling a washing machine for washing and rinsing by using an agitator mode and a permeation washing mode as well as increasing output by forming an outer rotor type motor. 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 shown in FIG. 1, the conventional fully automatic washing machine is rotatably installed in the outer tub 10 installed in the outer case 1 such that the dehydrating tank combined laundry tub 20 having a plurality of dehydrating holes is rotatable. 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. 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 received 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.

And the second object of the present invention is to provide an automatic washing machine that can prevent the unbalance of the washing tank 20 by applying the outer rotor type induction motor, and can make the length of the washing machine similar to the existing.

And the third object of the present invention is to maintain the system as described above, the stirring mode for washing without rotating the washing tank during the rotation of the washing blade, the transmission mode for rotating the washing blade and the washing tank at the same time, the compression direction to rotate in the forward and reverse direction It is to provide a washing machine to perform the mode.

When the sliding coupler 650 moves upward, the sliding coupler 650 becomes a second position clamped only to the lower dehydration shaft 140.

When the sliding coupler 650 is simultaneously engaged to the first position that moves downward, that is, the outer periphery of the rotor bushing shaft 534b and the lower dehydration shaft 140, the rotational force of the motor and the dehydration shaft Can be passed directly to 100.

The stopper 660 includes a fastening hole 660a for screwing the clutch assembly 600 to the lower clutch housing 300b, and a hinge hole 660c rotatably coupled to the end of the lever body 640a. ), A lever support part 660d for supporting the lever body part 640a, a spring 660e for providing elasticity during the tilting operation of the coupler support part 640b, and a spring support part 660f for supporting the spring 660e. It is configured to include).

An operation of the clutch assembly 600 will be described with reference to FIGS. 8A and 8B. 8B illustrates a connection link 630, a detachable lever 640, a sliding coupler 650, and a stopper at the first position in which the sliding coupler 650 is simultaneously engaged with the lower dehydration shaft 140 and the rotor bushing 534a. 660 is represented. 8A illustrates a connection link 630, a detachable lever 640, a sliding coupler 650, and a stopper 660 in the second position in which the sliding coupler 650 is engaged only with the lower dehydration shaft 140.

8B to 8A, the operation of sliding the sliding coupler 650 upward will be described.

First, the clutch operation motor 620 is rotated under control by a microprocessor. The link link 630 is pulled toward the clutch operation motor 620 by the rotational movement of the clutch operation motor 620. In addition, the detachable lever 640 illustrated in FIG. 7 is inclined toward the clutch operation motor 620 based on the hinge hole 660c by the movement of the link link 630. And by tilting the lever body portion 640a, the coupler support portion 640b is inclined so that an end thereof faces the lower end of the stopper 660.

At this time, the sliding coupler 650 lying on the upper end of the coupler support part 640b is slid upwards on the gear formed on the outer circumferential surface of the lower dehydration shaft and the gear formed on the outer circumferential surface of the rotor bushing shaft 534b. )do.

The brake assembly 700 for restricting the rotation of the drum 160 penetrates the side of the lower clutch housing 300b and protrudes out of the clutch housing 300. The brake assembly 700 is used when only the washing shaft 200 should be rotated during washing and when the dehydrating shaft needs to be stopped momentarily during dehydration.

As shown in FIG. 5, the brake assembly 700 penetrates through the brake lever 720 for operation, the upper clutch housing 300a, the brake lever 720, and the lower clutch housing 300b. A brake pad coupled to the shaft 740 and the through shaft 740 and connected to the brake spring 760 for providing elasticity of the brake lever 720 and the brake lever 720 to brake the drum 160. 780, the brake hinge shaft 790 is coupled to the end of the brake pad 780 and hinges when the brake lever 720 is pressed.

The brake assembly 700 is operated by the gear motor 761. That is, the brake assembly 700 is controlled by the operation of pulling and returning the brake lever 720 of the brake assembly 700 while the gear motor 761 operates in one or two stages.

When the gear motor 761 is not in operation, that is, in the off state, the brake pad 780 of the brake assembly 700 is contracted to surround and constrain the drum 160. However, when the gear motor 761 operates in the first or second stage, the brake pad 780 is relaxed, and the drum 160 is released from the brake pad 780 to allow free rotation.

When the drum 160 is restrained, the dehydration shaft 100 is also restrained, and the rotation of the washing tub 20 is impossible. However, when the drum 160 is released from restraint, the dehydration shaft 100 is freely rotatable, so the washing tub 20 is freely rotatable.

9 shows a gear motor 761 and each device for controlling the drive device and the drainage device.

As shown in FIG. 9, the brake lever 720 and the drainage device are formed in a straight line on the side of the gear motor 761. The gear motor 761 may simultaneously control the brake lever 720 and the drainage device by the connection lever 762 and the connection piece 763 of the gear motor 761.

The connection lever 762 may protrude from one side of the gear motor 761 to horizontally move the connection piece 763. And the other side of the connecting lever 762 is formed in the 'T' shape.

The connecting piece 763 includes a fixed piece 763a connected to the first spring 79 of the drain valve 64, a variable protrusion 767 coupled to a side of the fixed piece 763a, and the gear motor. It comprises a locking piece 768 caught in the connecting lever 762 of 761. The locking piece 768 forms a 'c' shape having a lower opening, and may hang the 'T' shaped locking protrusion 775 formed at an end portion of the connection lever 762.

Meanwhile, the control relationship between the brake lever 720 and the drainage device by the gear motor 761 will be described.

When the gear motor 761 operates in one stage, the connecting lever 762 moves the connecting piece 763 in parallel, and the brake lever 720 is pulled toward the gear motor 761. At this time, the brake fabric 780 of the brake assembly 700 is relaxed, and the drum 160 is released from restraint. However, as described above, since the drainage device operates only by a predetermined distance D within one rod by the first stage operation of the gear motor 761, the drain valve 64 is not opened.

On the other hand, when the gear motor 761 operates in two stages, the brake pad 780 is relaxed to release the drum 160 from restraint as in the first stage operation. However, due to the two-stage operation of the gear motor 761, the drainage device is operated through two rods, and the drain valve 64 is opened.

As described above, the driving device and the drainage device may be sequentially or simultaneously controlled by the first and second steps of the gear motor 761.

It looks at the various washing mode by the washing machine constituting the above configuration.

Referring to FIG. 8A, the washing tub 20 is fixed and looks at the case of the stirring mode in which washing and rinsing are performed while rotating only the washing blade 30.

First, the clutch operation motor 620 operates, and the link link 630 linearly moves toward the clutch operation motor 620. The detachable lever 640 is inclined by the linear motion of the connection link 630.

And due to the inclination, the coupler support part 640b pushes up the sliding coupler 650 upwards. As the sliding coupler 650 rises, the protrusion 652 of the sliding coupler 650 is coupled to the stopper 660. At this time, the sliding coupler 650 is moved to the position that can be engaged only in the lower dehydration shaft 140 (second position).

When the driving device is driven in the above state, the rotor assembly 500 rotates around the stator assembly 400 about the lower washing shaft 240. In addition, only the washing shaft 200 is rotated by the rotation of the rotor assembly 500, and the washing blade 30 is rotated along the rotational direction of the driving motor, and the washing and rinsing is performed.

At this time, the gear motor 761 does not operate and the brake pad 780 is fixed and the drum 160 is in a restrained state. And the drain valve 64 is also in a closed state.

At this time, looking at the rotational force transmission process, the rotational force by the rotor assembly 500, the rotor bushing shaft 534b of the rotor frame 530, the lower washing shaft 240, planetary coupled to the rotor bushing shaft 534b It is transmitted to the gear 220, the carrier 230, the upper washing shaft 210. At this time, the dehydration shaft 100 is in a state in which it is impossible to rotate due to the restraint of the drum 160 by the brake pad 780 and the restraint by the sliding coupler 650.

In the stirring mode, the planetary gear 220 rotates in the opposite direction to the sun gear 242 of the lower laundry shaft 240 in the state in which the drum 160 is restrained (off the brake pad) as described above. At the same time, the drum 160 revolves around the sun gear 242 in the same direction.

By the revolving of the planetary gear 220 as described above, the upper washing shaft 210 connected to the carrier 230 rotates in the same direction as the revolving of the planetary gear 220 in the upper dehydration shaft 120. The washing blade 30 coupled to the upper washing shaft 210 also rotates in the same direction as the planetary gear 220 to perform washing and rinsing.

On the other hand, while the washing tank 20 and the washing blade 30 rotates in the same direction at a high speed, the transmission washing mode in which washing and rinsing are performed will be described. And while the same as the permeable washing mode, but while maintaining the speed at which the wash water does not move to the outside of the washing tank 20, looks at the compression washing mode in the forward and reverse rotation.

Permeate washing is to rotate the washing tank 20 in a high speed as in the dehydration mode to create a 'V' shaped water in the washing tank 20 to proceed with the washing. Water that is moved to the outside of the washing tank 20 by the centrifugal force of the high speed rotation is washed while passing through the laundry.

Then, the water passing through the washing tank 20 is moved to the storage tank and rises upward in the storage tank wall surface. The water rises again to repeat the flow of the fluid flowing into the washing tank (20).

Compression washing as in the transmission mode by rotating the washing tub 20 and the washing wing 30 at the same time to create a 'V' shaped water. However, the washing is performed in a state in which water and laundry are compressed without being moved to the outside by slowing the rotation speed of the permeation washing mode. And the washing tank 20 and the washing wings 30 rotate in the forward and reverse directions.

With reference to Figure 8b looks at with respect to the transmission washing mode and the compressed laundry mode according to the present invention.

In the permeation and compression washing mode, the clutch operation motor 620 rotates in the direction opposite to the washing and rinsing stroke, and the detachable lever 640 is vertical. The coupler support part 640b is in an equilibrium state, and the sliding coupler 650 mounted on the coupler support part 640b moves downward by its own weight. As described above, the sliding coupler 650 moved downward is simultaneously engaged with the lower dehydration shaft 240 and the rotor bushing shaft 534b (first position).

In addition, the gear motor 761 operates in one stage, and the brake pad 780 of the brake assembly 700 is relaxed, thereby releasing the restrained drum 160. And the drain valve 64 is in a closed state.

When the driving device is operated in the above state, the washing shaft 200 is rotated by the rotation of the rotor assembly 500. The lower dehydration shaft 140 connected to the rotor bushing shaft 534b by the sliding coupler 650 rotates in the same direction as the washing shaft 200. The rotational force of the lower dehydration shaft 140 is transferred to the washing tank 20 through the drum 160 and the upper dewatering shaft 120 which can be freely rotated by the brake assembly 700 being turned on.

As described above, the washing blade 30 and the washing tank 20 are rotated at the same time in the same direction at a high speed to perform permeation washing and rinsing. The drain motor is off and closed.

At this time, the rotational force transmission process, the rotational force by the rotation of the rotor assembly 500, the rotor coupler shaft 534b of the rotor frame 530, the sliding coupler 650 engaged with the rotor bushing shaft 534b, the The lower dehydration shaft 140, the drum 160, the upper dehydration shaft 120, and the washing tank 20 engaged with the sliding coupler 650 are moved. At the same time, the washing shaft 200 embedded in the dehydration shaft 100 rotates together with the dehydration shaft 100 to transmit the rotational force to the washing blade 30.

Since the dewatering shaft 100 and the washing shaft 200 rotate at the same time as described above, the planetary gear 220 rotating and rotating inside the drum 160 by the sun gear 242 does not rotate and rotate. I can't. That is, by the rotation of the rotor assembly 500, the washing tank 20 and the washing wing 30 performs the washing and rinsing while rotating at high speed or forward and reverse at the same time.

Meanwhile, in the dehydration mode, the drum 160 is released from the restraint by the two-stage operation of the gear motor 761, and the drain valve proceeds in an open state.

As shown in FIG. 8B, the clutch operation motor 620 rotates the clutch operation motor 620 in a direction opposite to the washing and rinsing stroke, and the detachable lever 640 is vertical. The coupler support part 640b is in an equilibrium state, and the sliding coupler 650 mounted on the coupler support part 640b moves downward by its own weight. As described above, the sliding coupler 650 moved downward is simultaneously engaged with the lower dehydration shaft 140 and the rotor bushing shaft 534b (first position).

At this time, looking at the rotational force transmission process, the rotational force by the rotation of the rotor assembly 500, the rotor coupler shaft 534b of the rotor frame 530, the sliding coupler 650 meshed with the rotor bushing shaft 534b, The lower dehydration shaft 140, the drum 160, the upper dehydration shaft 120, and the washing tank 20 engaged with the sliding coupler 650 are moved.

The planetary gear 220 does not rotate because the drum 160 of the dehydration shaft 100 rotates at the same speed as the lower washing shaft 240. However, it rotates around the sun gear 242 between the sun gear 242 and the drum 160.

As described above, according to the present invention, the motor and the clutch assembly, which are conventional washing machine power transmission methods, are separately configured, and the motor is directly connected to the lower portion of the clutch assembly instead of connecting the belt assembly therebetween. In other words, by using the outer rotor-type motor solves the problem that the washing machine body is long, as well as the eccentricity of the washing tank (20).

Then, the rotor assembly constituting the rotating device is disposed outside the stator assembly as the stator to increase the power of the motor, and washing and rinsing are performed in the stirring mode and the permeation / compression mode.

Within the scope of the basic technical idea of the present invention, of course, many other modifications are possible to those skilled in the art. Therefore, the invention should of course be interpreted by the appended claims.

According to the present invention as described above, the outer rotor-type motor is directly connected to the lower side of the clutch has the advantage of increasing the output of the motor while preventing the eccentricity of the washing tank and the longer washing machine. In addition, the washing performance and the rinsing performance can be improved by performing the washing and rinsing in the transmission mode for rotating the washing blade and the washing tank at the same time with the increased output of the motor and the transmission / compression mode for rotating in the forward and reverse directions.
