Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for controlling a two-tub washing machine including a locking means for locking a lid arranged above a dehydrating basket containing an article to be dehydrated.

[0002]

In the two-tub type washing machine, a washing tub for washing and a dehydrating tub for dewatering are respectively arranged. Therefore, the diameter of the dehydration basket placed inside the dehydration tub is smaller than that of a fully automatic washing machine having a configuration in which the washing tub and the dehydration basket are combined, and its rotation speed is It is set about twice. Therefore, the laundry in the dehydration basket is likely to jump to the outside during the dehydration operation, and the rotation does not easily stop even if the power supply to the motor for rotating the dehydration basket is stopped.

Therefore, conventionally, when it is detected that the lid of the dehydration tank is opened during the dehydration operation, the rotation of the dehydration basket is stopped by applying braking. However, as described above, in the two-tank type, since the dehydration basket rotates at an extremely high speed, even if braking is applied, it may take about 10 seconds or more before the rotation actually stops.

Also, for example, Japanese Utility Model Publication No. 59-34475 discloses a technique for improving the convenience of use by locking the lid of the dehydration tank and displaying the state while the dehydration basket is rotating. There is. However, in this conventional technique, a control system for locking the lid is realized by a mechanical mechanism. Therefore, when the washing machine is continuously used, each part may be fatigued due to friction and the like, and there is a problem that the mechanism has poor durability and low reliability, and it is difficult to configure at low cost.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a control device for a two-tub washing machine which can perform lock control of the lid with higher reliability.

[0006]

In order to achieve the above object, a control device for a two tub type washing machine according to claim 1 is a dehydrating basket for containing an article to be dehydrated, and a motor for rotating the dehydrating basket. The washing tub and the dewatering tub are provided with a lid arranged above the dewatering basket and a locking means for locking the lid.
In the one that controls the two-tank type washing machine installed side by side ,
It is characterized by comprising a microcomputer for controlling the drive of the motor and controlling the locking and unlocking of the lid via the locking means in accordance with the progress of the dehydration operation.

According to this structure, the microcomputer controls locking and unlocking of the lid according to the progress of the dehydration operation, so that higher reliability can be obtained as compared with the conventional structure. Further, by controlling with a microcomputer, it is possible to take various control modes without complicating the configuration.

[0008]

Further, in this case, as described in claim 2 , the microcomputer is provided with a rotation speed [rp] of the dehydration basket.
When the product of m] and the radius [mm] of the dehydration basket exceeds 190985, the lid may be locked. That is,
When the above numerical value reaches 190986, the peripheral speed of the rotating dehydrating basket exceeds 20 m / s. By locking the lid before the peripheral speed of the dehydration basket exceeds 20 m / s, it is possible to reliably prevent the laundry from jumping out.

As shown in FIG. 7B, the rotation sensor 27
Is composed of an LED 27a as a light emitting element and a phototransistor 27b as a light receiving element.
When the rotating shaft 7a rotates, the projection 28b of the brake ring 28 blocks the optical path between them for a moment.

At the outer bottom of the dehydration tank 3, the stopper drive unit 2
9 is fixed. The stopper drive unit 29 has a solenoid 30 (see FIG. 2) and a stopper 31 built therein,
When the solenoid 30 is energized, as will be described later, the internal mechanism (for example, the same as the lock mechanism 20 described above) causes the stopper 31 to move to the rotation shaft 7 of the dehydrating motor 7.
It projects in the a direction. Then, the rotating shaft 7
When a is rotating, the protrusion 28b of the brake ring 28 contacts the protruding stopper 31 to restrain the brake ring 28, and the friction between the inner peripheral side of the ring portion 28a and the rotating shaft 7a is reduced. It acts so as to brake the rotation of the rotating shaft 7a and the dehydration basket 5. That is,
The brake mechanism 26 is composed of a brake ring 28 and a stopper drive unit 29.

FIG. 2 schematically shows the electrical construction of the washing machine. Microcomputer 32
Is composed of a CPU, a ROM, a RAM, etc., and the washing motor 6 is responsive to the operation signal of the operation switch 17, the sensor signal of the rotation sensor 27 and the on / off of the lid switch 50.
The driving of the washing machine is controlled by driving and controlling the dehydration motor 7. Further, the LED 18 of the operation display unit 12 is controlled to be turned on / off as necessary.

Power bus 3 connected to commercial AC power 33
Between 4a and 34b, triacs 35 to 41 and solenoids 23, 30, 42, 43 or motors 6, 7 are provided.
A series circuit with (coil of) is connected. And
The gate signal of each triac 35-41 is the microcomputer 3
Is given by 2.

When the triac 35 is turned on, the solenoid 23 is energized, the dehydration lid 15 is locked as described above, and when the triac 36 is turned on, the solenoid 30 is turned on.
Is energized, the stopper drive unit 29 of the brake mechanism 26 is driven, and the rotation of the dehydration basket 15 is braked. When the triacs 40 and 41 are turned on, the solenoid 4
Power is supplied to 2 and 43 respectively, and the water supply valve 14 and the drain valve are opened.

The triacs 37 and 38 are connected to the coils 6b and 6c of the washing motor 6 which is a condenser motor, respectively. When the triac 37 is turned on, the coil 6b is energized and the washing motor 6 is normally rotated. When the triac 38 is turned on, the coil 6c is energized and the washing motor 6 is reversely rotated. The triac 39 is connected to the coil 7b of the dehydrating motor 7 which is also a condenser motor, and when the triac 39 is turned on, the dehydrating motor 7 rotates.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 1 is a flowchart showing the control contents of the microcomputer 32 during the dehydration operation. The microcomputer 32 waits until the "dehydration" switch 17 of the operation display unit 12 is turned on (step S1), and during that waiting ("NO"), unlocks the dehydration lid 15 (unlock).
(Step S2). That is, the gate signal is not output to the triac 35.

When the "dehydration" switch 17 is turned on (step S1, "YES"), the microcomputer 32
Confirms that the lid switch 50 is off and then outputs a gate signal to the triac 39 to output the dehydration motor 7
Is rotated (step S3). Then, until the dehydration time set with reference to the timer has elapsed (step S4, "NO"), the rotation sensor 27 determines whether or not the dehydration motor 7 is rotating (step S5).

In step S5, if the dehydration motor 7 is rotating ("YES"), the microcomputer 32 outputs a gate signal to the triac 35 to drive the lock mechanism 20 to lock the dehydration lid 15 ( Step S6).
If the dehydration motor 7 is not rotating (“NO”)
It returns to step S4.

When the set dehydration time has elapsed (step S4, "YES"), the microcomputer 32 stops the output of the gate signal to the triac 39 and stops the dehydration motor 7.
Is stopped (step S7). Then, a gate signal is output to the triac 36 to output the brake mechanism 26.
The stopper driving unit 29 is driven to brake the rotation of the dehydration basket 15 (brake ON, step S8).

Subsequently, the microcomputer 32 determines whether or not the dehydration motor 7 is rotating by the rotation sensor 27 as in step S5 (step S9). If it is rotating ("YES"), the dehydration is performed. The lid 15 remains locked (step S10). Then, when the rotation of the dehydrating motor 7 and the dehydrating basket 5 is stopped by the braking by the brake mechanism 26 (step S9, “YES”), the microcomputer 32 stops the output of the gate signal to the triac 35 and dehydrates. The lid 15 is unlocked (step S11), and the process ends.

As described above, according to this embodiment, the microcomputer 32 controls the drive of the dehydration motor 7 to rotate the dehydration basket 5 and drives the lock mechanism 20 according to the progress of the dehydration operation. The lock / unlock of the dehydration lid 15 is controlled. That is, by locking the dehydration lid 15, it is possible to reliably prevent the laundry inside the dehydration basket 5 from jumping out of the rotary tub 3, and to prevent the laundry from being soiled or the cloth being damaged. Further, by controlling the lock mechanism 20 to be driven by the microcomputer 32, unlike the conventionally used control mechanism having a mechanical structure, the number of components that are fatigued by friction is extremely reduced.
Higher reliability can be obtained. Further, the microcomputer 32 can take various control modes without complicating the configuration.

Furthermore, when the microcomputer 32 stops energizing the coil 7b of the dehydrating motor 7, the braking mechanism 2
Since the rotation of the dehydration cage 5 is controlled by controlling 6 to stop the rotation of the dehydration cage 5, the rotation of the dehydration cage 5 can be stopped more quickly.
It is possible to release the lock of 5 at an earlier point. Then, the dehydration lid 15 is unlocked at the time when it is detected that the rotation of the dehydration motor 7 is completely stopped, so that there is no problem even if the dehydration lid 15 is opened at that time.

FIG. 8 shows a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described below. The configuration of the second embodiment is basically the same as that of the first embodiment, and only the control contents of the microcomputer 32 are slightly different.

That is, in the flowchart shown in FIG. 8, step S12 is arranged instead of step S5. In this step S12, the microcomputer 32, while performing the dehydration operation (step S4, "NO"),
Radius [mm] of the dehydration basket 5 and rotation speed [r of the dehydration motor 7 [r
It is determined whether the product of [pm] exceeds “190985”. The rotation speed is obtained from the sensor signal of the rotation sensor 27. That is, as described above, the rotation shaft 7 of the dehydration motor 7
LED that constitutes the rotation sensor 27 each time a rotates once
The optical path between 27a and the phototransistor 27b is blocked by the protrusion 28b of the brake ring 28. Therefore, the rotation speed of the dehydration motor 7 can be obtained by measuring the interval time.

The above numerical value "190985" is a value immediately before the peripheral speed of the rotating dehydrating basket 5 reaches 20 m / s. For example, when the radius of the dehydration basket 5 is 120 mm, the rotation speed corresponding to the above numerical value is 1591.54 rpm.
(Predetermined number of rotations). Therefore, (radius) x (number of rotations)
If the dehydration lid 15 is locked when the value exceeds "190985"("YES"), the peripheral speed of the dehydration basket 5 is 20 m /
It will lock before reaching s.

As described above, according to the second embodiment, in the microcomputer 32, the rotation speed of the dehydration motor 7 detected by the rotation sensor 27 becomes a predetermined rotation speed or more, and the rotation speed of the dehydration cage 5 and the dehydration cage 5 are increased. In the case where the product of the radius and the radius exceeds 190985, the dehydration lid 15 is locked, so that the laundry to be dehydrated can be reliably prevented from jumping out of the dehydration tub 3.

FIG. 9 shows a third embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described below. The configuration of the third embodiment is basically the same as that of the first embodiment, and only the control contents by the microcomputer 32 are different.

That is, in the flowchart shown in FIG. 9, when the microcomputer 32 determines "YES" in step S1, the microcomputer 32 proceeds to step S13 and locks the dehydration lid 15 at this stage. Then, the process proceeds to step S3. Further, when it is determined "NO" in step S4, the process returns to step S3. Then, step S8
After step S14, the process proceeds to step S14 and waits for a predetermined time of 30 seconds to elapse, and when 30 seconds elapse (“YE
S ”) The process proceeds to step S11 to unlock the dehydration lid 15.

As described above, according to the third embodiment, the microcomputer 32 releases the lock of the dehydration lid 15 after 30 seconds have passed since the power supply to the dehydration motor 7 was stopped. Braking by the action of dehydration basket 5
The lock is released at the stage where it is estimated that the rotation speed of has completely stopped. Therefore, even if the dehydration lid 15 is opened at that time, the laundry does not jump out.

FIGS. 10 and 11 show a fourth embodiment of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described below. FIG. 10 is a view corresponding to FIG. In the configuration of the fourth embodiment, the inner lid 44 is arranged above the dehydration tub 3, and the outer lid 45 is arranged above the inner lid 44. That is,
The lid of the dehydration tank 3 has a double structure.

The basic structure of the outer lid 45 is similar to that of the dehydration lid 15, and it is connected to the outer box 1 via the hinge portion 46, but it does not have a portion corresponding to the protrusion 19. Also,
Similarly, the inner lid 44 is also rotatably arranged above the dehydration tub 3 via a hinge portion 47, and a protrusion 48 having the same structure as the protrusion 19 of the dehydration lid 15 is arranged. . The lock mechanism 20 that locks the dehydration lid 15 in the first embodiment is arranged to lock the inner lid 44. Further, the lid switch 50 is arranged so as to turn on / off according to the open / close state of the outer lid 45 instead of the dehydration lid 15.

Next, the operation of the fourth embodiment will be described with reference to FIG. In the fourth embodiment, step S2
The object locked or unlocked in a, S6a, S10a, S11a is the inner lid 44 instead of the dehydration lid 15 in the first embodiment. And step S4
When it is determined to be "NO" in step S1, the microcomputer 32 determines whether or not the outer lid 45 is opened by turning on / off the lid switch 50 (step S15). If not, the microcomputer 32 proceeds to step S5. . Then, if the dehydration motor 7 is rotating (“YES”), step S
Moving to 6a, the inner lid 44 is locked.

On the other hand, if the outer lid 45 is opened during the dehydration operation (step S15, "YES"), the process proceeds to step S7 and the same processing as that at the end of the dehydration operation is performed until step S11a. That is, after the power supply to the dehydration motor 7 is stopped, the rotation of the dehydration basket 5 is braked, and when the rotation of the dehydration motor 7 is stopped, the inner lid 44 is unlocked (step S11a).

Then, after step S11a, it is determined in step S16 whether or not the dehydration is completed, as in step S4. If the dehydration operation is performed for the set time and it is determined to be “YES” in step S4 and then to step S16, it is naturally determined to be “YES” and the process is ended. Unlike this, as described above, the outer lid 45 is opened during the dehydration operation, and the step S7 is performed.
In the case of shifting from the above, since the dehydration operation time still remains, it is judged as "NO" in step S16, and the routine proceeds to step S17.

In step S17, similarly to step S15, it is determined whether or not the outer lid 45 is opened, and if it is opened ("YES"), the process proceeds to step S16. That is, if the outer lid 45 is still open, step S1
7, the state of waiting while looping around the loop of S16.
Then, when the outer lid 45 is closed again from that state, the microcomputer 32 determines "NO" in step S17, and proceeds to step S3. In this case, the dehydration motor 7 is restarted to restart the suspended dehydration operation. After that, if the set dehydration operation time has elapsed, it is determined to be "YES" in step S4, and thus the normal end sequence is executed.

As described above, according to the fourth embodiment, when the microcomputer 32 detects that the outer lid 45 is opened during the dehydration operation, it stops the energization of the dehydration motor 7 to rotate the dehydration motor 7. The inner lid 44 is unlocked when it is detected that is stopped. That is, the outer lid 45 and the inner lid 4
With the double structure of 4, it is possible to more reliably prevent the laundry inside the dehydration basket 5 from jumping out of the dehydration tub 3.

Even during the dehydration operation, the rotation of the dehydration basket 5 is braked when the outer lid 45 is opened. Therefore, for example, the user determines that the dehydration is already sufficient. Even if you want to take out the laundry from the dehydration basket 5,
The rotation of the dehydration basket 5 can be stopped within a short period of time and the dehydration basket 5 can be easily taken out.

The present invention is not limited to the embodiments described above and shown in the drawings, and the following modifications and expansions are possible. The braking means is not limited to the brake mechanism 26, and may be configured to apply the braking by using a disk arranged on the rotation shaft of the motor, for example. The configuration of the rotation speed detecting means is not limited to the rotation sensor 27, and may be an optical encoder. The predetermined number of rotations when locking the lid is not limited to the case where the product of the number of rotations and the radius in the second embodiment exceeds 190985, and a predetermined number of rotations can be set according to the individual design. good.
The predetermined time from when the power supply to the motor is stopped to when the lid is unlocked is not limited to 30 seconds as the predetermined time in step S15 of the third embodiment.
After operating, the time sufficient to estimate that the rotation of the dehydration basket 5 is stopped may be set.
