In the washing machine configured as described above, the operation of transmitting power to the washing shaft or the dewatering shaft is performed by the following actions.

Rotation force for driving the washing machine is generated by the electromagnetic interaction of the stator 40 and the rotor 50.

When the rotor 50 rotates, the driving mechanism 58 rotates, and rotational force is washed by the engagement of the serration 59 of the drive mechanism 58 and the serration 62 of the washing shaft 60. Delivered to shaft 60. When the washing shaft 60 is rotated is provided on the upper end of the washing shaft 60 to whip the laundry cloth and the wash water while only the washing blade is rotated inside the washing tank.

In this case, in order to rotate only the washing shaft 60, power is applied to the solenoid 90 so that the movable connector 80 is relatively moved upward. As such, when the movable connector 80 moves upward while overcoming the elastic force of the spring 80 ', the uneven portion 83 is joined to the uneven portion 97 of the yoke plate 2 96.

When the movable connector 80 is moved upward, the serration 86 engaged with the serration 58 'of the driving tool 58 no longer engages with the serration 58'. do. Therefore, the rotational force of the rotor 50 is not transmitted to the movable connector 80 so that the dehydration shaft 70 engaged with the movable connector 80 does not rotate. This state is shown in FIG.

In addition, in order to rotate the washing tank to perform dehydration of the laundry cloth, the washing shaft 60 and the dewatering shaft 70 are rotated at the same time at a high speed. To this end, the solenoid 90 is turned off. In this case, the movable connector 80 is pushed by the force of the spring 80 'and moves relatively downward.

The state at this time is shown in FIG. As shown, the upper end of the serration 86 of the connector 85 of the movable connector 80 is engaged with the serration 72 of the dehydration shaft 70, and the lower end of the drive port 58. Are interlocked with the serration 58 '.

In this case, the power of the rotor 50 is transmitted to the washing shaft 60 and the movable connector 80 by the drive port 58, the movable connector 80 to the dehydration shaft 70 Delivered. In this case, the laundry shaft 60 and the dehydration shaft 70 are rotated at the same time.

However, the conventional washing machine that delivers the power of the washing and dehydrating administration in the operation process as described above has caused the following problems.

First, the conventional washing machine performs the vertical reciprocating motion of the movable connector 80 which acts as a clutch during washing and dehydration operation by the power on / off operation of the solenoid 90.

On the other hand, the magnitude of the voltage applied to the solenoid 90 is given as much as possible to pull up the movable connector 80 to the upper enough when the initial starting voltage is applied, the movable connector 80 is yoke plate 2 After being matched to 96, only a voltage of a magnitude capable of holding it is applied. Therefore, since the holding voltage is lower than the initial starting voltage applied to the solenoid 90, the coupling state is separated when the movable connector 80 is not sufficiently coupled with the yoke plate 2 96. will be.

If the movable connector 80 and the yoke plate 2 96 are not sufficiently coupled by the above case, the movable connector 80 is driven by the spring 80 'force while the washing stroke is in progress. Pushed down. In this case, in the washing stroke for rotating only the washing shaft 60, the problem of rotating the dewatering shaft 70 like the washing shaft 60 occurs, resulting in unnecessary power consumption.

In addition, as the dehydration shaft 70 rotates together in the washing stroke, an overload occurs. At this time, the overload caused a problem of not performing the optimal washing administration while causing laundry damage, poking phenomenon and the like.

In addition, the conventional washing administration has caused a problem of increasing the noise, overloading the mechanical and circuit components due to the incorrect clutch operation and consequently shortening the life of the product.

From the above problems, the present invention intends to control the correct washing operation, including a means for monitoring whether the clutch operation is correctly performed.

Accordingly, an object of the present invention is to provide a washing control method of a washing machine that controls the clutch operation accurately to achieve an optimal washing administration.

Hereinafter, a washing machine according to the present invention will be described with reference to the accompanying drawings. And the structural configuration required in the description of the present invention will be described with reference to Figs.

7 is a configuration diagram for the control of the washing machine according to the present invention.

As shown, the control configuration of the washing machine includes a quantity detecting unit 300 for detecting the amount of laundry put into the washing tank, and a water level detecting unit 310 installed at one side of the washing tank to detect the level of water supplied to the washing tank. It is included. The amount of water detected by the quantity detecting unit 300 and the water level detected by the water level detecting unit 310 are applied to the controller 320 to be described later, and when the washing stroke, the rinsing stroke, the dehydrating stroke, etc. of the washing machine are performed, It is used as a signal.

In addition, the control configuration of the washing machine of the present invention includes a signal input unit 360 for inputting a signal selected by the user for washing. The input signal of the signal input unit 360 is applied to the control unit 320 to recognize the signal selected by the user.

The control unit 320 inputs signals of various sensing units so that the washing administration required by the user can be made, and controls the operation of various electronic components in the washing machine. In particular, the present invention controls the power supply and the power-off time of the solenoid 90 for the clutch operation for the vertical movement of the movable connector 80 is operated according to whether or not the power supply of the solenoid 90.

The controller 320 performs control to monitor whether the controlled clutch operation is correctly performed. If the clutch value operation is not performed correctly, the clutch operation is controlled to be performed again. In addition, the control unit 320 controls the drainage and water supply according to the detected amount of water and the water level.

The current value is used as a basic signal for monitoring whether the clutch operation is correctly performed in the controller 320. That is, the controller 320 determines whether the clutch operation is normal based on the current value detected by the current sensor 370.

In general, during the washing administration only the washing blade inside the washing tank by the rotation of the washing shaft 60 is rotated. At this time, the current detected according to the rotation of the washing blade is included in a predetermined value (about 2A to 3A range. However, during the dehydration operation, the washing shaft 60 and the dehydration shaft 70 are rotated together and require a lot of power. Therefore, the current value detected in proportion to the power consumed also flows about 7A to 8A, which is relatively higher than that during the washing process, and thus the clutch operation is performed because the current value detected during washing and dehydrating strokes is different. It is possible to determine whether or not this has been done normally.

In addition, the current sensing unit 370 preferably uses a current sensing unit for detecting an overcurrent of the switching element IGBT that operates in order to supply a high voltage power to a motor generating power of the washing machine.

And the control configuration of the washing machine in the present invention, the solenoid power supply unit 330 for supplying power to the solenoid 90 is supplied for the clutch operation, opening and closing between the external supply source and the water supply pipe to supply water to the washing tank It includes a water supply valve 350 for, and a drain valve 340 for operating when draining the water in the washing tank to the outside. The solenoid power supply 330, the water supply valve 350, the drain valve 340, and the like are controlled by the control unit 320.

Reference numeral 380 denotes a power supply unit 380 for providing power to a motor (not shown) for generating power of the washing machine. When power is transmitted to the motor through the power provider 380, the rotor 50 is rotated by the power of the motor.

Next, the washing control method of the washing machine according to the present invention having the above configuration will be described in detail.

In the present invention, the clutch operation operated by supplying power to the solenoid 90 may be divided into a washing stroke for rotating only the washing shaft 60 and a dehydrating stroke for rotating the washing shaft 60 and the dewatering shaft 70 together. have.

8 is a flowchart illustrating an operation according to a washing operation in the washing machine according to the present invention.

When the laundry to be washed is put in the washing tank and the washing start signal is selected by the signal input unit 360 provided outside the washing machine, power is supplied to the electronic parts inside the washing machine, and the washing state becomes a standby state for washing. 100 steps). At this time, the washing start signal of the signal input unit 360 is input to the control unit 320, the control unit 320 performs the control for washing.

First, the control unit 320 reads the detection signal of the quantity of water contained in the washing tank through the quantity detecting unit 300. The control unit 320 detects the amount of water contained in the washing tank by the amount of detection value, and performs a control to supply water proportional thereto.

That is, the controller 320 opens the water supply valve 350 so that the water supplied from the outside is supplied to the washing tank. The control unit 320 controls the water supply valve 350 in the opened state while detecting the water level through the water level detecting unit 310 until the required water supply is made according to the amount of water detected by the quantity detecting unit 300. . When the water supply is completed, the water supply valve 350 is closed.

When the preparation for washing operation is completed as described above, the control unit 320 supplies a signal to the power providing unit 380 to generate the rotational force of the rotor 50. At this time, the rotor 50 prepares for the normal rotation while performing a simple rotation, not the normal rotation (step 102). That is, in the simple rotation state, the rotational force of the rotor 50 is very weak.

In the state in which the rotor 50 makes the simple rotation in step 102, the control unit 320 supplies power to the solenoid 90 through the solenoid power supply unit 330 (step 103).

In step 103, since only the washing shaft 60 for rotating the washing blade needs to be rotated during the washing administration, the connecting state of the washing shaft 60 and the dehydrating shaft 70 by the shandong east of the movable connector 80 is connected. This is to perform the clutch operation to separate the.

That is, when power is supplied to the solenoid 90, the movable connector 80 is moved upward in FIG. 1 (step 106). The movable connector 80 is moved upward by overcoming the elastic force of the spring 80 'by the magnetic field generated by the solenoid 90 (step 109), wherein the uneven portion of the yoke plate 2 (96) ( 97, the uneven part 83 of the movable connector 80 is molded (step 112).

In addition, due to the upward movement of the movable connector 80, the serration 86 engaged with the serration 58 'of the drive tool 58 is no longer engaged with the serration 68'. . Therefore, since the rotational force of the rotor 50 generated during the washing stroke is not transmitted to the movable connector 80, the rotational force is not transmitted to the dehydration shaft 70 engaged with the movable connector 80. (Step 115).

When the clutch operation by the above steps is completed, the controller 320 controls the power provider 380 to supply normal power to a motor (not shown). In this way, the rotor 50 performs the normal rotation (step 118).

When the rotor 50 rotates in this way, the driving mechanism 58 rotates, and the rotational force is caused by the engagement of the serration 59 of the drive mechanism 58 and the serration 62 of the washing shaft 60. This is delivered to the washing shaft 60 (121). When the washing shaft 60 is rotated, the washing stroke is provided on the upper end of the washing shaft 60 while the washing blade inside the washing tank is rotated to stir the washing cloth and the washing water (step 124).

When the above process is performed and the washing stroke is performed according to the rotation of the washing blade, the controller 320 performs an operation for monitoring whether the normal clutch operation according to the yoke coupling with the movable connector 80 has been performed. 127 steps).

The controller 320 reads the current value detected from the current sensor 370. At this time, if the detected current value is higher than a predetermined value (although a slight difference occurs depending on the product, but generally about 3A), it is determined that the clutch operation is not normally performed. This is because the current value detected from a motor (not shown) for generating the rotational force of the rotor 50 is proportional to the power used. That is, compared with the case where the washing shaft 60 is rotated, when the dehydration shaft 70 and the washing shaft 60 are rotated together, relatively high power is consumed, and a high current value is detected.

If the clutch operation is not normally operated according to the determination, the control unit 320 returns to step 102 to perform the clutch operation again.

When the clutch operation is normally performed according to the determination, the control unit 320 proceeds with the washing administration for the set time and ends the washing administration when the set time is completed (step 130 and step 133).

In the embodiment of the present invention shown in FIG. 8 as described above, by monitoring whether the clutch operation is normally controlled during the washing stroke, the control so that the optimum washing stroke can be achieved by rotating only the washing blade by the washing shaft 60. It describes the operation to do.

However, the clutch operation is not only performed during the washing stroke, but also in the rinsing stroke and the dehydrating stroke.

The following briefly describes the clutch operation process performed during the dehydration stroke.

When the laundry administration shown in FIG. 8 is completed, the control unit 320 performs a dehydration stroke. First, the control unit 320 controls to drain the water inside the washing tank. That is, by controlling the drain valve 340 in the open state, the water in the washing tank is discharged to the outside. When the water level is finally required, the controller 320 adjusts the drain valve 340 to the closed state and completes the draining operation.

When the drainage operation is completed as described above, the controller 320 applies a power cutoff signal to the solenoid power supply unit 330 while applying power for the simple rotation of the rotor 50 to supply the power supply of the solenoid 90. Block it.

When the power supply of the solenoid 90 is cut off, the movable connector 80, which has been moved upward by the force of the generated magnetic field of the solenoid 90, is pushed down by the force of the spring 80 '.

That is, as shown in Figure 6, the upper end of the serration 86 of the coupling body 85 of the movable connector 80 is meshed with the serration 72 of the dehydration shaft 70, the lower end is Meshes with the serration 58 'of the drive opening 58; That is, the laundry shaft 60 and the dehydration shaft 70 is to be connected by the movable connector (80).

In this case, the power of the rotor 50 is then transferred to the washing shaft 60 and the movable connector 80 by the drive port 58 during the dehydration stroke, and the movable connector 80 in the dehydration operation. Delivered to a contraction 70. In this case, the laundry shaft 60 and the dehydration shaft 70 are rotated at the same time.

When the clutch operation connecting the dehydration shaft 70 and the washing shaft 60 is completed, the controller 320 controls the rotor to rotate normally. That is, when power for rotation of the rotor 50 is transmitted, the power of the rotor 50 is transmitted to the washing shaft 60 and the movable connector 80 by the drive port 58, The movable connector 80 is transmitted to the dehydration shaft (70). In this way, the laundry shaft 60 and the dehydration shaft 70 is rotated at the same time. At this time, the rotational force of the rotor 50 rotates the washing shaft 60 and the dewatering shaft 70 at the same time at high speed. That is, the washing blade by the washing shaft 60 and the washing tank by the dehydration shaft 70 is rotated at the same time.

On the other hand, the control unit 320 reads the current value detected from the current sensing unit 370 when the washing tank and the washing blade is rotated. At this time, if the read current value is higher than the predetermined value 3A, it is determined that the clutch operation has been normally performed. If the current value is smaller than the predetermined value 3A, it is determined that the clutch operation is incompletely performed and the clutch operation is re-executed. To control.

As described above, the present invention monitors whether the clutch operation for separating the washing shaft and the dewatering shaft performed in the washing stroke and the rinsing stroke, and the clutch operation for the connection of the washing shaft and the dewatering shaft performed in the dehydrating stroke are normally operated. Characterized in that the optimal washing state can be made. In the present invention, it is determined whether the normal operation of the clutch operation is a current value proportional to the driving power.

Thus, the washing control method of the washing machine according to the present invention, the clutch operation is performed normally, it is possible to obtain the effect of preventing damage and damage to circuit parts and mechanical parts due to the overload generation and shortened life.

In addition, the present invention can prevent the increase in power consumption caused by the rotation of the de-shrinkage during the washing administration, increase in noise, thereby increasing the purchasing power for the product.

In addition, the present invention has the advantage of being able to prevent damage to the laundry, tangling, etc. by pursuing the washing administration to rotate only the washing wing.
