2. Description of the Related Art Generally, a washing machine is an apparatus for washing a laundry soiled with various contaminants to an original state according to an arbitrary setting mode without damaging the cloth quality. Recently, as the cloth quality is diversified, a washing machine having a further improved washing power is desired.

FIG. 1 is a cross-sectional view showing an example of a conventional washing machine, and is a view showing a fully automatic single-tub washing machine.
This is the content disclosed in Japanese Patent Laid-Open Publication No. 7-227494, for example. Explaining the overall configuration of the one-tub type washing machine, an outer tub 2 is provided in the washing machine case 1, and a washing / dehydrating tub 3 is provided in the outer tub 2. Washing wings 4 such as an agitator in the washing and dehydrating tub 3.
And a washing motor 5 is provided below the outer tub 2. A clutch 9 and a speed reducer 8 are provided above the motor 5, and a washing shaft 6 and a dehydration shaft 7 are directly connected between the speed reducer 8 and the washing wing 4. The drain valve 12 and the drain hose 13 are provided in a predetermined area below the outer tank 2,
After the washing and rinsing steps, the contaminated water is discharged to the outside. Further, a tub cover 10 is provided at the upper end of the outer tub 2. In addition, the fluid balancer 1
1 is provided above the washing / dehydrating tub 3 to prevent vibration and noise during washing and dehydration.

In the conventional washing machine having the above-described structure, the washing blade 4 and the washing / dehydrating tub 3 are simultaneously rotated during the washing process so that the washing power can be improved. A motor for driving the dehydration tank is separately provided, or one of the motors is provided with a speed reducer 8. But,
The washing machine has a washing wing 4 and a washing / dehydrating tank 3 during a washing process.
Only the configuration in which and are simply rotated in the opposite direction and the washing control method for this are described. Further, the rotational force of the washing motor 5 is reliably transmitted to the washing shaft 6 and the dehydration shaft 7 with a simple structure in which the speed reducer 8, the clutch 9 and the washing motor 5 are integrated. However, it is impossible to accurately transmit the rotational force without precise control of the motor 5, and a washing machine having such a structure has never been realized.

FIG. 2 is a vertical cross-sectional view showing another example of a conventional washing machine. Such a fully automatic washing machine is known from Japanese Patent Laid-Open Publication No. 8-57186. . The overall configuration of the above fully automatic washing machine is the same as that of FIG. 1 described above. However, different points are related to the lower structure of the outer tub 2 and the washing / dehydrating tub 3, and depending on the type of laundry and whether a cover (not shown) can be opened in the washing / rinsing process. It is a combination of fixed or rotating modes. In particular, the structural part is that the upper washing shaft 6a is connected to the lower washing shaft 6 via a speed reducer 8 as a planet gear.
b, the lower washing shaft 6b is connected to the washing motor 5
Linked to The lower dehydration shaft 6c is the brake drum 2
It is connected to the upper dehydration shaft 6d via 0. The lower washing shaft 6b is connected to the pulley 14a of the washing motor 5 via the pulley 14b and the belt 15.

In the conventional fully automatic washing machine constructed as above, if the user sets a washing mode for washing rough laundry, the actuator is operated for a predetermined time, as shown in FIG. The lever 27 shown is pulled for a certain distance. At this time, the brake bands that have restrained the brake drum 20 are separated by a certain gap, and the washing / dehydrating tub 3 is switched to a free rotation mode, so that the washing wing 4 and the washing / dehydrating tub 3 are rotated in opposite directions. Here, the clutch gear is already meshed with the clutch piece.

On the other hand, when the user sets the washing mode for washing the fine laundry, the actuator is turned off, the brake lever 27 is in the original state, and the brake band (not shown) holds the brake drum 20. The restraining state is reached, and the washing / dehydrating tub 3 is in the fixed mode.
Here, when the user opens the cover in the mode in which the washing / dehydrating tub 3 is free, the washing / dehydrating tub 3 is suddenly switched to the fixed mode in consideration of stability.

FIG. 3 (a) is a diagram for explaining the operation of the clutch during the washing stroke applied to FIG. 2, which is disclosed, for example, in Japanese Patent Laid-Open Publication No. 8-57187. When the brake lever 27 moves a distance (A ′) from L to L1 according to the turn-on of the actuator, the two clutch pieces 23 attached to the tip of the arm 22 are already engaged with the clutch gear 21. Since the brake band (not shown) is separated from the brake drum 20 by a constant gap, the upper dehydration shaft is in a free state. In other words, when the clutch piece 23 is engaged with the clutch gear 21, the clutch spring (not shown) does not integrally (do not connect) the drum fitted in the lower washing shaft and the lower dewatering shaft, so that the washing is performed. The wings and the washing / dehydrating tub are rotated in reverse. This state is the free mode of the washing / dehydrating tub 3. On the other hand, when the actuator is turned off, the spring 26 returns to the original state, that is, the position L, and the brake band restrains the brake drum 20. This state is the fixed mode of the washing / dehydrating tub 3.

FIG. 3 (b) is a diagram for explaining the operation of the clutch in the dehydration process applied to FIG. 2. When the brake drum 20 is completely released in the dehydration process, the washing / dehydrating tub 3
Can be rotated at high speed. On the other hand, when the lever 27 is moved from L to L2 by a distance A ″ by energizing the actuator,
The two clutch pieces 23 attached to the tip of the arm 22 come to be disengaged from the clutch gear 21. For this reason,
Since the drum fitted in the lower washing shaft and the lower spinning shaft are integrated by the restoring force of the clutch spring (not shown), the washing wing and the washing / dehydrating tub rotate in the same direction. That is, the rotational force of the motor of the washing machine is transmitted straight to the washing wing and the washing / dehydrating tub without passing through the speed reducer.
A dehydration process is performed.

The conventional washing machines constructed in this way are
As described with reference to FIG. 1, the washing wing 4 and the washing / dehydrating tub 3 are simultaneously rotated during the washing and dewatering process to improve the washing power. However, since the lid stops immediately when it is opened, the user may mistake this as a failure. Also,
If the washing blade is overloaded during the washing process, the planetary gear of the reduction mechanism rotates the dehydration shaft and the washing shaft in opposite directions to release the overload. However, until the overload is released, the above-described overload release operation should be repeated, so that the washing time and the washing power are reduced. Although not shown in detail in the drawings, there is no mention of the clutch structure and drainage structure that should be performed prior to rotating the washing / dehydrating tub and the washing wing at the same time in the washing process, rinsing process and dehydration process. It is in. Moreover, there is no mention of the gear motor applied to the drainage structure.

As shown in FIG. 8B, an upper output cam 91-1 having different circumferential radii, and the upper output cam 91-1.
A lower output cam 91-2 having a smaller size and different circumferential radii on both sides, and the upper output cam 9
1-1 and the first and second contact points 92a and 92b and the common contact point 93-2, which are arranged close to the lower output cam 91-2, and the upper output cam 91-1 and the lower output cam 91 of the output cam 91 are provided. -Gear motor 6 based on the -2 linked operation
Control the 1-stage or 2-stage operation of 1.

9 (a) to 9 (c) are schematic diagrams showing the contact relationship between the output cam of the gear motor of FIG. 8 (a) and the switch, and FIGS. 10 (a) to 10 (c). FIG. 11 is a circuit diagram showing a drive circuit of the gear motor of FIG. 8A, and FIG. 11 is a timing diagram of a triac and a switch according to power supply to the gear motor of FIG. 8A.

First, in FIG. 10A, the terminal 93-
When the terminal 2 and the terminal 93-3 are opened, they are exchanged and connected to each other, which is often caused by an operator during service. In this state, in the gear motor 61, when the first triac TR1 is turned on for the one-step operation, one side of the power supply is the first triac TR1 → the first switch SW1.
→ The other end of the power supply is met through the second switch SW2. At this time, when the second switch SW2 is turned on, the shot state occurs, and the triac TR1 inside the controller is destroyed. Therefore, in order to turn off the second switch SW2, the cam groove 91-3 is added to the lower output cam 91-2.

9 (a) and 10 (a),
This is a state in which power is not supplied to the gear motor 61, that is, an initial state in which the first triac TR1 and the second triac TR2 are all turned off. At this time, the first switch SW1 connected to the first triac TR1
Is in the turned-on state, the second triac TR
The second switch SW2 connected to 2 is turned off (see the timing diagram of FIG. 11).

Next, FIG. 9 (b) and FIG. 10 (b) show
This is a state in which the one-step operation of the gear motor 61 is completed. That is, from the state of FIG. 9A and FIG.
When only TRIAC TR1 is turned on, relay R
Since power is automatically supplied to Y and power is supplied to the gear motor 61 via the first switch SW1,
The connecting lever 62 is pulled, and the output cam 91 rotates counterclockwise. How much the output cam 91 rotates (usually, when the time t1 elapses, the first switch SW1
Is turned off), the first switch SW1 of the upper output cam 91-1 is turned off, and the second switch SW1 of the lower output cam 91-2 is turned off.
The switch SW2 is turned on. That is, since the first switch SW1 is turned off, the gear motor 61
Then, the power is cut off and the output cam 91 and the connecting lever 62 are stopped, but the first triac TR1 is continuously turned on (see the timing chart of FIG. 11).

Then, FIG. 9C and FIG.
This is a state in which the two-step operation of the gear motor 61 is completed. That is, from the state of FIG. 9 (b) and FIG. 10 (b),
When the second triac TR2 is turned on, power is supplied via the second switch SW2 and the gear motor 6
Since 1 rotates, the output cam 91 rotates and the connecting lever 62 is pulled into the gear case. Here, as shown in FIG. 11, normally, the one-step operation is completed when the time t1 elapses. However, for more stable operation, after the time t1 + α elapses from the start point of the one-step operation, Start the two-step operation. When the output cam 91 rotates (usually, the second switch SW2 is turned off when the time t2 elapses), the second switch SW2 is also turned off and the power supply to the gear motor 61 is cut off. The cam 91 and the connecting lever 62 stop. In this state, the first TRIAC TR1
By controlling so that the relay RY is turned on only, the connecting lever is not restored from the drive state of the relay RY and is stopped in the two-step operation 62-2.

On the other hand, in FIG. 10 (a), the operator uses the terminals 93-2 and 93-3 for after-sales service.
Even if the wires are exchanged and connected after opening the
Even if the first triac TR1 is turned on for one operation, the second switch SW2 is turned off, so the gear motor 61 does not operate, but no shot occurs. In this way, even when an operator makes a wrong connection, by forming an open loop by the contact operation of the double output cam, it is possible to prevent the destruction of the elements in the control unit.

On the other hand, FIG. 12 is a block diagram showing a drive device of the fully automatic washing machine of the present invention.

Referring to FIG. 4 and FIG. 12, the drive device is provided with a microcomputer 110 for controlling input / output for various controls for controlling external peripheral devices, and a user setting mode for the microcomputer 110. And a key operation unit 112 for displaying the operating state of the washing machine, and the washing / dehydrating tub 43 based on the control of the microcomputer 110.
Water level sensor unit 11 for sensing the amount of washing water thrown into
1, a water supply valve drive unit 114 for controlling the water supply valve 59 for supplying proper washing water into the washing / dehydrating tub 43 based on the water level detection of the water level sensor unit 111, and during the stroke of the washing machine. A lid / open detection unit 117 for detecting the open state of the lid 50 and a power supply to the gear motor 61 based on the control of the microcomputer 110 to control the one-stage or two-stage operation of the drain valve 59 in the drainage device. It has a first-stage and a second-stage drainage drive unit 113, 115.

In the driving device constructed as described above,
The microcomputer 110 controls peripheral devices of the fully automatic washing machine, and the key operation unit 112 inputs a key signal in the user setting mode to the microcomputer 110. Then, the key operation unit 11
When the water level is set by 2 or the water level is set by sensing the amount of cloth, the water supply valve drive unit 114 opens the water supply valve 59. Then, the water level sensor unit 111 senses whether or not the wash water has been supplied up to the set water level according to the opening of the water supply valve 59.
The washing motor 45 is driven by the washing motor 45 while the drain valve driving unit 113 pulls the drain valve 64 to the first stage.
3 and the washing wing 44 are rotated together. During the washing process by the rotation of the washing / dehydrating tub 43 and the washing wing 44, the lid / open sensing unit 117 senses whether or not the lid 50 of the washing machine is opened, and the signal sensed here is sent to the microcomputer 110.
To provide. Next, when the set washing time elapses, the two-stage drain valve driving unit 115 opens the drain valve 64 in two stages for intermittent dehydration and main dehydration.

FIG. 13 shows the algorithm of the above driving device.
And FIG. 14 will be described in detail.

FIG. 13 is a flow chart showing an embodiment of the washing control method of the present invention, showing the operating state of the washing machine when the lid is opened during the washing and rinsing process.

When the fully automatic washing machine first enters the easy-to-wash mode (S130), it determines whether it is a washing process or a rinsing process (S131). If the washing / rinsing process is not performed in the determining step S131, another process is performed, and then the process ends (S140). If the washing / rinsing process is performed in the determination step (S131), the washing wings 44
And the washing / dehydrating tub 43 are mutually rotated (S132).
That is, when the washing / rinsing process is performed, the washing wing 44 and the washing / dehydrating tub 43 are rotated in opposite directions, and when the washing / rinsing process is not performed, another process is performed (S140).

Then, when the washing wing 44 and the washing / dehydrating tub 44 rotate in mutually opposite directions by sensing the washing and rinsing stroke, it is sensed whether the lid is open or not (S133). When the lid 50 is opened, an abnormal alarm sound is generated to inform that the operation is not normal (S135). Such an alarm sound may be used to mean a pause for loading laundry. After sounding the alarm sound as described above, the washing wing 44 and the washing / dehydrating tank 4 are provided for the safety of the user.
Stop all three. At this time, the user can add additional laundry (S139). On the contrary, the lid
If the lid is not opened in the open sensing stage (S133), it is determined whether or not the set time for the washing / rinsing process has elapsed (S134), and then, when the set time has elapsed, another process is performed (S140) and the setting is performed. If the time has not elapsed, the process proceeds to the step (S132). Then, after a certain period of time has passed since the washing wing 44 and the washing / dehydrating tub 43 were stopped (S137), whether the lid 50 is open or not is again sensed (S138), and the lid is closed. Rotates the washing wing 44 and the washing / dehydrating tub 43 in mutually opposite directions to perform the washing / rinsing process for the remaining time.

However, the steps (S135) (S13)
In 6), the washing wing 44 and the washing / dehydrating tub 43 are all stopped to generate an abnormal alarm, but the washing wing 4 is opened when the lid 50 is opened.
4 and the washing / dehydrating tub 43 immediately stop, so that the user may mistakenly think that the washing machine is out of order. In other words, since an abnormal alarm sound is generated when the lid is opened, many users do not think that it is a safety process or a process for loading laundry when the washing wings and the washing / dehydrating tub are immediately stopped. In order to prevent the user from erroneously recognizing that the sudden stop of the washing wing and the washing / dehydrating tank after the alarm sounds, it may be changed as follows. That is, although not shown, even after detecting the opening of the lid, the washing wing and the washing / dehydrating tub are rotated in reverse for a certain period of time, and then an abnormal alarm is generated, and the washing wing and the washing / dehydrating tub are activated. May be stopped.

On the other hand, FIG. 14 is a flow chart showing a method for controlling the operation of the washing machine when the lid is opened. When the washing / rinsing process is selected, the washing wing 44 and the washing / dehydrating tub 43 are mutually operated. Rotate in the opposite direction (S130 to S13
2). Next, when the lid is opened, an abnormal alarm is generated, and the washing wing 44 and the washing / dehydrating tub 43 are reversely rotated at a low speed in order to consider the safety of the user and to notify that there is no failure (S133). (S135) (13
6). Further, a step of generating a cloth amount detection signal (S135-1) can be added to the step (S135).
In step 36), a cloth amount re-sensing step (S136-1) can be added. Therefore, the user can confirm that the washing machine is in a normal state because the washing wing 44 and the washing / dehydrating tub 43 rotate for several seconds when the lid 50 is opened. The subsequent steps are shown in FIG.
This is the same as the method described in 3.

15 and 16 are flow charts showing another embodiment of the washing control method of the present invention.

In the washing control method, first, when the washing process starts, it is judged whether or not the water level is set by the user (S150), and if the water level is not set, the process proceeds to the cloth amount sensing course, After sensing the water level suitable for the amount of cloth,
Proceed to the continuous washing process (S151). The step (S1
When the user sets the proper water level in 51), the normal water level and the proper water level are set by the data set (S152) based on the water level (S152). Next, the water supply valve 59 is turned on (S153) to re-supply water up to the set water level (S154), and then the water supply valve 59 is shut off (S46).
Then, after initializing all the washing time (T) (S1
56), with the gear motor 61 driven to pull the drain valve to the first stage (S157), the washing / dehydrating tub 43 and the washing wing 4
4 is rotated normally / reversely (S158) to perform the washing process. That is, the fully automatic washing machine of the present invention has the above-mentioned step (S
158), the washing / dehydrating tub 43 is operated in the rotation mode from the fixed mode. In other words, in the clutch structure of the washing machine, the clutch lever 69 connected to the drain valve 64 is pulled by a distance that does not allow natural drainage,
When the clutch lever 69 is not operated by the brake lever 70, the washing / dehydrating tub 43 and the washing wing 44 rotate in the forward or reverse direction. That is,
It is to show the operation in the washing process and the rinsing process.

After that, the lid / open sensor 117
Detects whether the lid of the washing machine being washed is rotated by the rotation of the washing / dehydrating tub 43 and the washing wing 44 (S159), but if the open state of the lid 59 is not sensed, the set washing is performed. The washing / dehydrating tub 43 and the washing wing 44 continuously rotate for a period of time. Then, when it is detected that the washing machine lid 59 is opened in the step (S159), the initialized time is counted, and the counted time (T) is counted.
And a predetermined time (t1) are compared (S160). Here, in the step of comparing times (S160), as shown in FIG. 11, the time point at which the gear motor 61 is driven is determined. This is a very important step because it determines from which point in time the clutch mechanism is activated.

As a result of the comparison in the step (S160), when the counted time, that is, the open time of the washing machine lid 59 does not exceed the predetermined time and the user closes the washing machine lid 59 (S161), the gear The motor 61 is driven to pull the drain valve 64 to the first stage (S162), and then the washing / dehydrating tub 43 and the washing wing 43 are rotated in the forward or reverse direction (S163). In other words, in the above-described series of steps (S161 to S163), the user opens the washing machine lid 59 within a predetermined time to check the rotating state of the washing / dehydrating tank 43 with the naked eye of the user, and then closes the lid 59. When it is done, make sure that the preset washing process is performed.

As a result of the comparison in the step (S160), if the counted open time of the washing machine lid is longer than or equal to the predetermined time, the gear motor 61 is driven to move the drain valve 64 to the first stage. Return to the original position (S16
4) Make only the washing wing 44 rotate (S16)
5). That is, the fully automatic washing machine of the present invention operates in the rotating / fixed mode.

In the middle of washing, the user opens the washing machine lid and keeps the washing / dehydrating tub 43 and the washing wings 44 for a predetermined time.
When the set washing time elapses (S166) after it is possible to directly see the rotation of the
Is pulled (S167) to rotate the washing / dehydrating tub 43 and the washing wing 44 in the same direction to enter the dehydration process stage of intermittent dehydration and main dehydration (S168). That is, the fully automatic washing machine of the present invention operates in the high speed rotation mode. Therefore, when the lid is opened, the washing / dehydrating tub 43 and the washing wing 44 are rotated for a predetermined time, and then, the process of rotating only the washing wing 44 removes an element that the user mistakenly recognizes as a failure of the washing machine. At the same time, the cleaning power can be improved.

[0083]

As described above, according to the drainage device of the fully automatic washing machine and the washing control method therefor of the present invention, the following effects can be obtained.

First, since the clutch piece is arranged coaxially with the connecting piece that connects the drainage device and the gear motor, the drainage device and the clutch structure can be made compact.

Secondly, since the variable protrusion for adjusting the clearance of the clutch piece is attached to the guide elongated hole of the connecting piece for the first and second operations of the drainage device, the clearance adjustment of the clutch lever is easy.

Thirdly, in the clutch structure, the clearance between the clutch lever and the brake lever can be easily adjusted with the clearance adjusting screw.

Fourth, since the output cam in the gear motor is formed in a double structure and the contacts of the switch are operated safely, the quality and reliability of the washing machine can be improved.

Fifth, shots are prevented by the switching contacts of the dual output cam when the connecting terminals of the gear motor are mis-connected, so that the peripheral circuits can be protected.

Sixth, since a warning sound is generated when the washing machine lid is opened, a safety display can be given to the user.

Seventh, when the lid of the washing machine is opened, the washing / dehydrating tub and the washing wing rotate for a few seconds, and then only the washing wing rotates. This prevents malfunction and misidentification by the user. The phenomenon that the dehydration tub and the washing wing rotate in reverse can be confirmed with the naked eye.

Eighth, it is possible to adjust the gap between the drainage device and the clutch structure.
