Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control method for a fully automatic washing machine.

[0002]

2. Description of the Related Art FIGS. 1 and 2 show an example of a fully automatic washing machine. As is well known, an outer tub 4 is suspended by a plurality of suspension bars 3 having a vibration isolator 2 inside an outer box 1, In this outer tub 4, a washing tub 5 having a large number of water drain holes formed on its peripheral wall is provided.
Inside the washing tub 5, rotary blades 6 such as an agitator are provided.

A mechanism including a motor 7 fixed to the outer tub 4 positioned below the outer tub 4, a rotation shaft of the motor 7 including a belt 8, a bearing portion and a speed reduction mechanism for switching between washing and dehydration. The washing shaft fixed to the rotary blade 6 and the dewatering shaft fixed to the washing tub 5 are coaxially connected to each other via the portion 9.

The upper opening of the outer box 1 is covered with a top cover 10 and a lid 11, and the top cover 10 sets the washing operation contents such as washing, rinsing and dewatering operation times and water flow strength. An operation panel 12 is provided.

Then, the washing process is started in accordance with the water level, the strength of the water flow and the washing time which are preset in a control device (not shown) using a microcomputer or the like, or set in the operation panel, and the washing process is finished. Draining afterwards, then the dehydration process starts with the set dehydration time, after the completion of the dehydration process, the rinse process starts with the set water level, the strength of the water flow, the rinse time, and the final dehydration process after the completion of the rinse process. Then, all the operation processes automatically proceed and end.

By the way, the washing process and the rinsing process are shown in FIG.
As shown in the energization pattern to the motor 7, the motor 7 is alternately rotated right and left, and this rotational force is transmitted to the washing shaft at the set rotation angle and the set number of times. By reversing the rotary blades 6, a water flow is generated in the washing tub 5 to stir the laundry and rinse it easily. In this case, in the conventional rinsing process, the rotation angle of the rotary blade 6 and the number of times of reversal are set to the same as those in the washing process, for example, because the dirt adhering to the laundry has already been removed. Only the washing time is set shorter than the washing time.

[0007]

When the rinsing time is shortened as described above, the time for collecting lint during the rinsing operation is shortened, and the lint collecting rate is higher than that during the washing operation. As a result, the laundry is finished with the thread dust attached to the laundry.

Even if the rinsing time is set shorter than the washing time, the rotating blade rotates at the same rotation angle and the same number of reversals as in the washing step, so that the mechanical force applied to the laundry in the entire washing step is large, Larger scratches on the laundry.

It is an object of the present invention to provide a method for controlling the operation of a fully automatic washing machine, which solves the above-mentioned disadvantages of the prior art, prevents thread waste from adhering to the laundry, and at the same time reduces damage to the laundry. is there.

[0010]

In order to achieve the above-mentioned object, the present invention automatically operates the washing process, the dehydrating process, the rinsing process and the dehydrating process, and various courses are performed depending on the operation contents of each of these processes. In the operation control method of the fully-automatic washing machine in which is set, the rotation angle of the rotary blade during the rinsing step, the number of times of reversal is smaller than the rotation angle during the washing step, and the course is set less than the number of times of reversal, , Providing a course in which the dehydration time of the dehydration step before the rinse step is set shorter than the dehydration time of other courses, and the rotation angle of the rotor blade during the rinse step, Set to less than the number of inversions and set to water rinsing operation that rinses while supplying water, and the dehydration time of the dehydration process before the rinse process is the same as the dehydration time of other courses. It is an gist providing a course was also shorter.

[0011]

According to the present invention as set forth in claim 1, the rotating angle of the rotary blade during the rinsing step is smaller than that during the washing step, and the number of reversals of the rotary blade during the rinsing step is smaller than that during the washing step. Since the number of times of inversion is set to be smaller than the number of times of inversion, the amount of lint generated during the rinsing process is reduced, and the amount attached to the laundry is also reduced. At the same time, the mechanical force applied to the laundry is reduced, and the damage to the laundry is reduced.

According to the present invention of claim 2, in addition to the above action, the dehydration time before the rinsing step is shortened,
It is possible to reduce the clinging of the laundry to the washing tub at the time of dehydration, and as a result, as described above, even if the rotation angle of the rotary blade is small during the rinsing process and the number of inversions is small, the laundry is stirred during the rinsing process. Is sufficiently performed and the rinsing performance is not deteriorated.

According to the third aspect of the present invention, in addition to the above action, since water rinsing is performed in the rinsing step, the rinsing performance is improved even when the rotation angle of the rotor blade is small during the rinsing step and the number of reversals is small. improves.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 3 is an energization pattern of the motor during the rinsing step in the operation control method for the fully automatic washing machine of the present invention.
Since the overall structure of the washing machine in which the method of the present invention is carried out is as already described with reference to FIGS. 1 and 2, detailed description thereof is omitted here.

The basic structure of the operation control method for the washing machine of the present invention is similar to the conventional one, and the washing process, the dehydration process, the rinsing process and the dehydration process are automatically advanced to start and end the washing process. In the process and the rinsing process, the motor 7 is alternately rotated clockwise and counterclockwise, and this rotary force is transmitted to the washing shaft to reverse the rotary blade 6 at a set rotation angle and a set number of times. Then, a water flow is caused in the washing tub 5 to stir the laundry and rinse it easily.

In the present invention, in the rinsing step, the rotation angle of the rotary blade 6 is smaller than the rotation angle in the washing step as shown in the energization pattern for the motor 7 in FIG. The course set in the control device is provided less than the number of inversions during the washing process.

At the same time, in this course, the dehydration time in the dehydration step before the rinse step is set to be shorter than the dehydration time in the other courses, and in this rinse step, the washing and rinsing operation is performed while supplying water to the washing tub 5. Set.

In the rinsing process of the course set as described above, the rotation angle of the rotor 6 is smaller than the rotation angle in the washing process, and the number of reversals of the rotor 6 is smaller than the number of reversals in the washing process. Therefore, the water flow generated by the reversal of the rotary blades 6 is weak and the generation time is short, so that the generation of lint is reduced, and as a result, the amount of the waste adhered to the laundry is reduced.
At the same time, the mechanical force applied to the laundry is reduced, and the damage to the laundry is reduced.

Further, since the dehydration time before the rinsing step is shortened, the sticking of the laundry to the washing tub 5 at the time of the dehydration can be reduced. Even if the rotation angle is small and the number of reversals is small, the laundry is immediately unraveled in the washing tub 5 at the start of the rinsing step, the stirring is sufficiently performed, and the rinsing performance is not deteriorated.

Further, since water rinsing is performed in the rinsing step of this course, the rinsing performance is improved even when the rotation angle of the rotary blade is small and the number of reversals is small during the rinsing step.
