DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control apparatus for automatically operating a series of operations such as a dishwasher, a clothes dryer, a drum-type washing machine, and a fully automatic washing machine.

[0002]

2. Description of the Related Art Heretofore, in a control device of this kind of equipment, a series of operations of the equipment have been automatically operated.

[0003] In recent years, the number of electric appliances in homes has increased, and the power consumed in homes has been steadily increasing. In addition, inverter control is often used for motor control, and large current consumption is increasing. In such a situation, in a device equipped with a load that consumes a large current, such as a heater or an inverter control type motor, the power consumption changes during a series of operations of the device, and when the power consumption increases, the device itself becomes large. It is not unusual for a breaker to shut off.

Further, in the case of a device connected to the same breaker as such a device, the power supply was suddenly interrupted during a series of operations. If the power supply is interrupted due to a breaker interruption or the like, the device returns to the power-off state regardless of a series of operation progress status. In such a case, a person has set a series of operations of the device again and started the operation from the beginning.

[0005]

In such a conventional device, after the breaker is turned on again, a person resets the device from the beginning and starts a series of operations of the device from the beginning. In this case, power, water, and the like required until the power supply is interrupted due to the breaker being cut off or the like are wasted.

[0006] In a dishwasher, a fully automatic washing machine, or the like, which is an apparatus for washing with a detergent, the detergent must be re-added, and the detergent, time and labor are wasted.
In a dishwasher, a drum-type washing machine, or the like, which is a device for heating water, the heated water is drained, and the power and time required for the water and the heating are wasted. In this case, not only are costs for detergents, water, electricity, etc. wasted, but also the environment is not easy.

The present invention has been made to solve the above-mentioned problem. Even when the power supply is interrupted, it is possible to determine at which stage the previous operation was interrupted. A first object is to make it possible to operate more continuously.

Further, in the case of a device having a load that consumes a large current, even when the power supply is interrupted by the operation of the device itself, it is possible to determine at which stage the previous operation was interrupted and to supply the power again. The second object is to make it possible to continue the operation when the operation is stopped.

[0009]

In order to achieve the first object, the present invention sequentially controls a series of operations of a device and a non-volatile storage means whose stored contents are not erased even when power is not supplied. Control means, wherein the control means appropriately stores the operation status in the non-volatile storage means during a series of operations of the device.

Thus, even if the power supply is interrupted, the control means can determine at what stage the previous operation was interrupted, and when the power is supplied again, the control means continues from the interrupted stage. It can be made drivable.

In order to achieve the second object, there is provided a non-volatile storage means in which stored contents are not erased even when power is not supplied, and a control means for sequentially controlling a series of operations of the equipment. After starting a series of operations of the device, before driving a large current consuming load that consumes a large current, or between driving of a large current consuming load, the operating state may be appropriately stored in a nonvolatile storage unit. It was made.

Thus, in the case of a device having a load that consumes a large current, even when the power supply is interrupted by the operation of the device itself, the control means can determine at what stage the previous operation was interrupted. When the power is supplied again, the operation can be continued from the interrupted stage.

Embodiments of the present invention will be described below with reference to the drawings. The appliance will be described as a large current consumption load, a dishwasher as a device having a heater, and a fully automatic washing machine as a device having an inverter-controlled motor as a typical device.

(Embodiment 1) First, a dishwasher will be described as an example using a heater.

As shown in FIG. 2, the washing tank 1 is
Is stored inside, and washing water is supplied from a water supply valve (water supply means) 3 and stored at the bottom. The cleaning nozzle 4 is
It is rotatably supported in the washing tank 1 and jets washing water toward the tableware 2. The cleaning pump 5 supplies the cleaning water to the cleaning nozzle 4.
It is sent to. The water level sensor 6 detects the water level in the cleaning tank 1 and outputs the same as an electric signal.

The heater (high current consumption load) 7 is provided in the cleaning tank 1
Located at the bottom of the heater to heat the wash water. The thermistor (temperature detecting means) 8 is attached to the bottom of the cleaning tank 1 so as to be in close contact with the outside, and detects the temperature of the cleaning water and the temperature of the cleaning tank 1 by heat conduction. The drainage pump (drainage means) 9 is for discharging the washing water in the washing tank 1. Blower fan 10
Is for sending out steam in the cleaning tank 1 and is discharged from the exhaust port 11 to the outside of the machine. The tableware basket 12 is for disposing the tableware 2. The door 13 opens and closes when the tableware 2 stored in the washing tank 1 is taken in and out. The door opening / closing detecting means 14 detects whether the door 13 is open or closed.

The control device 15 controls the water supply valve 3, the washing pump 5, the heater 7, the drain pump 9, the blower fan 10 and the like to sequentially control the washing, rinsing, and drying steps, as shown in FIG. It is composed.

As shown in FIG. 3, the input means 16 includes a power switch 16a for turning on / off the power, a start switch 16b for starting and temporarily stopping the operation, and a course switch 16c for setting a course.

The control means 17 is constituted by a microcomputer, and the water supply valve 3, the washing pump 5, the heater 7, the drainage pump 9, and the blower fan are provided through the load control means 18 according to the input set by the input means 16. A load such as 10;
The display unit 19 and the notifying unit 20 are controlled according to a predetermined sequence.

The display means 19 comprises a light emitting diode. As shown in FIG. 3, a course display section 19a for displaying course contents and an abnormal content display section 19 for displaying abnormal contents.
b, an operation display section 19c for displaying an operation state, and the like. The notifying means 20 is constituted by a piezoelectric buzzer. The power supply circuit 21 generates a power supply for the control unit 17 and the like. The non-volatile storage means 22
The operating state of a series of operations is stored by the control means 17.

The operation of the above configuration will be described with reference to FIG. 4. In step 23, the user first supplies power by inserting a power plug into a power outlet or a breaker. In step 24, if there is no operation status data stored in the non-volatile storage unit 22, the control unit 17 determines that the operation has been completed normally last time, and in step 25, turns off the power. And waits until the user presses the power switch 16a.

During this standby period, the user places the tableware 2 in the tableware basket 12 and stores it in the washing tank 1, puts the detergent therein, and sets it so that it can be operated. When the power switch 16a is pressed in step 26, the process waits in step 27 until the start switch 16b is pressed. When the start switch 16b is pressed, at step 28, the control unit 1
7 writes the data of the start into the nonvolatile storage means 22.

Next, at step 29, the ambient temperature is inputted from the thermistor 8, and at step 30, the operation time of each step is set. Next, in step 31, a water supply process is performed. This means that water or hot water is supplied from the water supply valve 3 until the water level sensor 6 provided at the bottom of the washing tank 1 detects a predetermined water level. Then, in step 32, a cleaning step is performed.

The cleaning pump 5 and the heater 7 are energized, and the cleaning water is heated by the cleaning pump 5 while being heated.
Washing is performed by ejecting the washing nozzle 4 toward the tableware 2. At this time, the temperature of the washing water is detected by the thermistor 8, and the control means 17 keeps track of the temperature of the washing water.

When the temperature of the washing water reaches a predetermined temperature and a predetermined time has elapsed from the start of the cleaning, the control means 17
Ends the washing process, and in step 33, performs a drainage process. This is to energize the drain pump 9 to drain the water in the washing tank 1. When drainage is completed, step 34
Then, the control means 17 writes, in the nonvolatile storage means 22, data indicating that the cleaning step has been completed.

Next, at step 35, a water supply step of supplying fresh water or hot water is performed, and at step 36, a rinsing step is performed. In this case, the same operation as in the above-described cleaning step is performed for several minutes. Thereafter, in step 37, a drainage process is performed. Then, in step 38, the control unit 17 writes data indicating that the first rinsing process has been completed in the nonvolatile storage unit 22. If necessary, repeat the water supply, rinsing and draining steps several times.

Next, at step 39, a water supply step of supplying fresh water or hot water is performed, and at step 40, a heating rinsing step is performed. In this case, the same operation as in the above-described cleaning step is performed, and when the temperature reaches a predetermined temperature and a predetermined time has elapsed, this is ended. Then step 4
At 1, the drainage process is performed. Then, in step 42,
The control unit 17 writes data indicating that the heating and rinsing process has been completed in the nonvolatile storage unit 22.

Finally, at step 43, a drying process is performed. This is to operate the blower fan 10 to discharge the steam in the washing tank 1 to the outside of the apparatus, and at the same time, intermittently supply electricity to the heater 7 to heat the tableware 2 and dry the attached water droplets. It is. Then, in step 44, the control unit 17 deletes the data of the operation status stored in the nonvolatile storage unit 22. Thereafter, in step 45, the notification means 20 is sounded to notify the user of the end of driving.

After the drying step, the temperature in the cleaning tank 1
In order to prevent re-adhesion to the tableware 2 due to high humidity, a step of intermittently operating the blower fan 10 called a dry keeping step is performed in step 46 to discharge moisture in the washing tank 1. In addition, the operation of the blower fan 10 promotes a decrease in the temperature in the cleaning tank 1. After the end of the dry keeping process, the control means 17 turns off the power in step 47.

In step 24, if there is operation status data stored in the non-volatile storage means 22, the control means 17 determines that the power supply was interrupted during the previous operation, and According to the situation data, turn on the power and set the course and driving process again,
In step 49, it is assumed that the ambient temperature is set to 20 ° C. without inputting the ambient temperature from the thermistor 8. Then, in step 50, the piezoelectric buzzer of the notification means 20 is sounded to notify that the previous operation has been interrupted.

Thereafter, in step 51, the apparatus is set to a temporary stop state and the apparatus is made to stand by. At step 52, an error display indicating that the operation was previously interrupted is displayed on the error content display section, and at step 53, the user sets the start switch 16
Steps 52 to 53 are repeated until b is pressed. When the start switch 16b is pressed in step 53, the operation is started again in step 54 from the last step written in the non-volatile storage means 22 in the previous operation.

As described above, according to this embodiment, even when the power supply is interrupted during the operation, the previous operation state can be determined when the power is next supplied, and the previous operation was interrupted. From the stage, the operation can be continued.
Thereby, it is possible to avoid wasting water, detergent, heated hot water, electric power, and time during the previous operation.

In particular, according to the present embodiment, writing to the non-volatile storage means 22 is performed at the end of the drainage stroke. Therefore, when restarting the operation, the operation is started from the water supply stroke or the drying stroke. . Therefore, the water, hot water and detergent used for washing or rinsing at the time when the power supply was interrupted will not be drained when restarting operation,
Can be used reliably.

In this embodiment, the data is written in the non-volatile storage means 22 at the end of the drainage process, but the same effect can be expected if the writing is performed after the drainage process is completed and before the water supply process is started. . For example, after the drainage is completed, the operation is stopped for a certain period of time, and then the nonvolatile storage unit 22 is stopped.
The same effect can be expected when writing is performed on the non-volatile storage means 22 after the small amount of water is supplied or after the small amount of water is supplied to the nonvolatile storage means 22 again.

If writing is performed in the non-volatile storage means 22 in all steps, such as a water supply step, a drain step, and a washing step, a minimum of 14 is required until one course is completed.
Although the number of times of writing must be increased, the number of times of writing in the nonvolatile storage means 22 is immediately exceeded, and the useful life of the product is shortened.
If it is limited to the end of the drainage process, the service life is at least 5 times, so that the useful life of the product can be sufficiently secured.

Erasing the operating condition data stored in the non-volatile storage means 22 at the end of the drying process is not a series of operations for ensuring the basic performance of the dishwasher in the dry keeping process. This is because, even if the power supply is interrupted during the dry keeping process, it is not necessary to continue from the dry keeping process.

Further, during the dry keeping process, the power outlet may be disconnected because the process is a process after the original series of operations is completed. In this case, the continuation of the dry keeping process at the time of the next power supply leads to a reduction in usability, which is not preferable. However, the same effect can be obtained even when the power supply is interrupted during the dry keeping process, or even when the operation is continued from the dry keeping process.

In this embodiment, the operation status is stored in the nonvolatile storage means 22 during the operation. However, when the power supply is interrupted, the operation of the nonvolatile storage means 2 is stopped.
The same effect can be obtained even if the driving condition is stored in the storage device 2.

In the present embodiment, only the step 52 is displayed when the previous operation was interrupted. However, when the operation is not temporarily stopped, all operations during the operation after the power is supplied again, or the power is supplied again. The same effect can be obtained even if an abnormality is displayed until after the operation is completed.

In this embodiment, at step 49,
Although the ambient temperature is assumed to be 20 ° C., this is an example, and there is no need to stick to 20 ° C. Further, it is not necessary to fix the temperature to one temperature, and the same effect can be obtained even if one is selected from a plurality of values depending on the operating condition and the value of the thermistor.

(Embodiment 2) Control means 17 in FIG.
Is instructed to turn off the power by the input means 16,
The operation status stored in the non-volatile storage unit 22 is erased, and even if the power-off instruction is given by the input unit 16, if the operation status stored in the non-volatile storage unit 22 is deleted, the operation status is deleted again. I try not to. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIG. 5. If the user wants to stop the operation during the normal operation, the power switch 16a is pressed in step 55, and the process moves to step 56. . At step 56, it is determined whether or not the data of the driving condition is cleared. If not, the data of the driving condition is cleared at step 57. Then, in step 58, a power-off process is performed.

If it is determined in step 56 that the driving situation has been cleared, the process proceeds to step 58,
The power-off process is performed without clearing the operation status data again.

As described above, according to the present embodiment, by pressing the power switch 16a during operation, when the power-off process is performed, the operation status data can be reliably cleared. Even if the power supply is interrupted, it is possible to avoid restarting from an unintended operation. Also, even if the power is repeatedly turned on and off,
The number of times of writing to the non-volatile storage unit 22 is only one, so that the number of times of writing to the non-volatile storage unit 22 can be reduced and reliability can be improved.

(Embodiment 3) When a special demonstration is instructed by the input means 16 in the control means 17 in FIG.
The operating state is not stored in the nonvolatile storage means 22. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIG. 6. When the power switch 16a is pressed while the power is off, the power is turned on at step 59. At this time, in step 60, it is determined whether or not the course switch 16c has been pressed.
In step 61, the power is turned on. If the course switch 16c is depressed, it is instructed to enter a special demonstration, and a display is displayed on the display means 19 in the same manner as when the power is turned on, and in step 62, a water supply process is performed.

This special demonstration is for a service person to operate a course in a short time in order to confirm whether or not the device can be operated. However, at this time, the data of the start is not written as in the first embodiment. When the water supply is completed, in step 63, the cleaning process is performed.
Thereafter, in step 64, a drainage process is performed. When drainage is completed, a drying step is performed in step 65. Also in this case, unlike the first embodiment, data indicating that the cleaning process has been completed is not written. After the drying process in step 65 is completed, the operation status data is cleared in step 66, and the power is turned off in step 67.

As described above, according to the present embodiment, during the operation of the special demonstration, the data of the driving condition is not written.
Even if the power supply is interrupted during the operation of the special demonstration, the operation is not restarted from an unintended situation when the power is supplied again. In addition, even if the service person unplugs the power outlet during the operation of the special demonstration, the operation can be performed without any problem at the next energization.

When confirming the operation at the time of shipment from the factory, by using the special demonstration, the operation of the special demonstration does not have to be waited for, and the operation is not terminated by pressing the power switch 16a. Driving status can not be left. Thus, when the product is handed to the user, it is possible to reliably start from the power-off.

The operation content of the special demonstration is not limited to the above description, and the same effect can be obtained with any operation content as long as it is a special operation used for inspection of a service person or a factory. Can be.

Further, the method for entering a special demonstration is not limited to the above description, and the same effect can be obtained by any input method. For example, at the start of power supply, when a specific switch is pressed to input a special demonstration or when the power switch 16a is pressed,
The same effect can be obtained even if a special demonstration is input by simultaneously pressing a plurality of switches.

Further, in this embodiment, the operation status is not cleared when the special demonstration is started, but the same effect can be obtained even if the operation content is cleared when the special demonstration is started. .

In this embodiment, the operation status is cleared at the end of the operation of the special demonstration. However, since the operation status is not written during the operation, it is not necessary to clear the operation status at the end of the operation. Therefore, the same effect can be expected without clearing the operation status at the end of the operation.

(Embodiment 4) Control means 17 in FIG.
When the special display is instructed by the input unit 16, the operation status stored in the nonvolatile storage unit 22 is displayed on the display unit 19. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIG. 7. If the power switch 16a is pressed while the power is off, the power is turned on at step 68. At this time, it is determined in step 69 whether or not the start switch 16b has been pressed, and if not, the power is turned on in step 70 as usual. If the start switch 16b has been pressed, it is determined that a special display has been instructed, and the operation status is displayed on the abnormality content display section 19b of the display means 19 in step 71. afterwards,
In step 72, the power is turned off.

As described above, according to the present embodiment, by instructing a special display, the data of the driving condition can be displayed. Even if the power is cut off, the operating condition at the time of occurrence of the abnormality can be accurately grasped, so that a serviceman can perform repairs in a shorter time than before.

As for the contents of the special display operation, the same effect can be expected by any display method as long as the operation status is displayed. For example, the course display unit 19
A similar effect can be obtained if the driving condition can be determined by displaying the value in a or by changing the blinking cycle of the light emitting diode.

The method for entering the special demonstration is not limited to the above description, and the same effect can be obtained by any input method. For example, at the start of power supply, a special display is instructed by pressing a specific switch, or when the power switch 16a is pressed,
The same effect can be obtained even when a special display is instructed by simultaneously pressing a plurality of switches.

In this embodiment, the input means 16 is built in the device. However, it is possible to give an instruction to the control means 17 by connecting it to a remote controller or when necessary. Can expect the same effect.

(Embodiment 5) Next, an embodiment of a fully automatic washing machine will be described as an example using a motor of an inverter control system. In particular, in recent years, an inverter-controlled fully automatic washing machine that consumes a large current has appeared, and it is expected that a breaker will be dropped when driving an inverter-controlled motor built in the device.

As shown in FIG. 9, the water tub 73 includes a washing and dewatering tub 74, and a stirring blade 7 is provided at the bottom of the washing and dewatering tub 74.
5 is provided rotatably. The speed reduction mechanism 76 reduces the driving force from the DC brushless motor 77 and transmits it to the stirring blade 75 during washing, and transmits it to the washing and dewatering tub 74 during dehydration. The switching between the dehydration and the washing at this time is performed by driving the drain valve 78. When the drain valve 78 is driven, the washing water is drained and the clutch of the speed reduction mechanism 76 is switched to perform the dehydration operation.

The washing tub lid 79 has a folding structure having a hinge at the center, and covers the upper opening of the outer frame 80.
The water supply valve 81 supplies tap water, and supplies water to the washing and dewatering tub 74. The water level detecting means 82 detects the water level by converting the water pressure at the connection (trip point) 83 below the water tank 73 into an electric frequency. The pulse generator 84 is attached to the DC brushless motor 77, outputs a pulse corresponding to the rotation speed of the DC brushless motor 77, and inputs the pulse to the controller 85.

The control device 85 is configured as shown in FIG. 8 and controls the operations of the DC brushless motor 77, the drain valve 78 and the like, and sequentially controls a series of steps such as washing, rinsing, and dehydrating. The control device 85 includes a control unit 86 including a microcomputer that determines the amount and quality of the cloth based on the output pulse of the pulse generation unit 84;
Power switching means 87 for controlling a drain valve 78, a water supply valve 81, and the like in accordance with a signal from the CPU, an inverter control means 88 for controlling a DC brushless motor 77, and an input means 90 comprising a key switch disposed in an operation panel 89.
And display means 9 comprising a display device such as a light emitting diode
1 and a notifying means 92 comprising a piezoelectric buzzer or the like. 93 is an AC power supply.

As shown in FIG. 10, the input means 90 comprises a power switch 90a for turning on / off the power, a start switch 90b for starting and temporarily stopping the operation, a course switch 90c for setting a course, and the like. In addition,
The display means 91 is constituted by a light emitting diode, and is constituted by a course display section 91a for displaying course contents, an abnormal content display section 91b for displaying abnormal contents, an operation display section 91c for displaying an operation state, and the like.

The DC brushless motor 77 has a stator (not shown) having a built-in three-phase winding 94 and a rotor (not shown) having a two-pole permanent magnet on a ring.
And position detecting means 95 for detecting the position of the rotor.

Inverter control means 88 is an inverter 96 composed of a switching element comprising a parallel circuit of a power transistor (IGBT) and a reverse conducting diode.
, A diode bridge 97 and a choke coil 98
And a smoothing capacitor 99. The non-volatile storage means 100 stores the operating status of a series of operations by the control means 86.

The operation of the above configuration will be described with reference to FIG. 11. In step 101, the user first supplies power by inserting a power plug into a power outlet or a breaker. At step 102, the control unit 86
If there is no operation status data stored in the non-volatile storage means 100, it is determined that the operation was normally completed last time,
In step 103, the power is turned off. In step 104, the process waits until the user presses the power switch 91a.

During this standby period, the user puts the clothes to be washed into the washing and dewatering tub 74, puts the detergent, and sets the washing machine to be able to operate. At step 104, the power switch 9
When 1a is pressed, the process waits at step 105 until the start switch 90b is pressed. Start switch 90
When “b” is pressed, the control unit 86 writes data of the start to the nonvolatile storage unit 100 in step 106.

Next, at step 107, a water supply process is performed. This is to supply water or hot water from the water supply valve 81 until the water level detecting means 82 detects a predetermined water level. Then, in step 108, a washing process is performed. this is,
By energizing the inverter control means 88, the DC brushless motor 77 is reversed, and
This is for washing clothes to be washed. At this time, when the washing time according to the water level has elapsed, the control means 86 ends the washing process, and in step 109, performs the drainage process.

This is to energize the drain valve 78 to drain the water in the washing and dewatering tub 74. When drainage is completed,
In step 110, an intermediate dewatering process is performed. This is because the washing and dewatering tub 74 is rotated at a high speed by continuously energizing the DC brushless motor 77 for a short time, thereby squeezing out the detergent liquid that has soaked into the clothes, and ensuring the rinsing performance. Thereafter, in step 111, the control unit 86 writes data indicating that the washing process has been completed in the nonvolatile storage unit 100.

Next, in step 112, a water supply step of supplying fresh water or hot water is performed, and in step 113, a rinsing step is performed. In this case, the same operation as in the above-described cleaning step is performed for several minutes. Then, at step 114,
Perform drainage process. Then, in step 115, an intermediate dehydration step is performed, and in step 116, the control means 86 writes data indicating that the first rinsing step has been completed in the nonvolatile memory means 100.

Next, in step 117, in order to perform the second rinsing, a water supply step of supplying fresh water or hot water is performed, and in step 118, a rinsing step is performed. afterwards,
In step 119, a drainage process is performed, and in step 120
Then, the control means 86 writes data indicating that the second rinsing step has been completed in the nonvolatile storage means 100. If necessary, the water supply, rinsing, draining and intermediate dewatering steps are repeated several times.

Finally, in step 121, a dehydration step is performed. In this case, the same operation as in the above-described intermediate dehydration step is performed for several minutes. This is done to dry the rinsed clothes and to remove some water. Then, in step 122, the control unit 86 sets the nonvolatile storage unit 1
The operation status data stored in 00 is deleted. Then, in step 123, the alarm means 92 is blown.
Inform the user of the end of driving. Thereafter, the control unit 86 turns off the power in step 124.

In step 102, if there is operation status data stored in nonvolatile storage means 100, control means 86 determines that power supply was interrupted during the previous operation, and in step 125, Depending on the situation data,
The power is turned on, the course, the driving process, and the like are set again. At step 126, the notifying means 92 is sounded to notify that the previous operation was interrupted.

Thereafter, in step 127, the apparatus is set to a temporary stop state and the apparatus is put on standby. At step 128, an abnormality display indicating that the previous operation was interrupted is displayed on the abnormality content display section 91b, and at step 129, steps 128 to 1 are performed until the user presses the start switch 90b.
Repeat up to 29. When the start switch 90b is pressed in step 129, the operation is started again in step 130 from the last step written in the non-volatile storage means 100 in the last operation.

As described above, according to this embodiment, even when the power supply is interrupted during the operation, the previous operation state can be determined when the power is next supplied, and the previous operation was interrupted. From the stage, the operation can be continued.
Thereby, it is possible to avoid wasting water, detergent, hot water, electric power, and time during the previous operation.

In particular, according to the present embodiment, writing to the non-volatile storage means 100 is performed at the end of the drainage stroke, so that when restarting the operation, the operation is started from the water supply stroke or the dehydration stroke. . Therefore, the water, hot water and detergent used for washing or rinsing when the power supply is interrupted will not be drained when operation is resumed,
Can be used reliably.

In this embodiment, the data is written in the non-volatile storage means 100 at the end of the intermediate dewatering process. However, the same effect can be expected if the data is written after the drain process is completed and before the water supply process is started. it can. For example, the same effect can be obtained even when writing is performed in the non-volatile storage means 100 upon completion of the drainage process, or when the water supply process is performed again in earnest after writing in the non-volatile storage means 100 after supplying a small amount of water. it can.

Further, if data is written to the non-volatile storage means 100 in all steps such as a water supply step, a drain step, and a washing step, at least one cycle is required until one course is completed.
Writing must be performed four times. In this case, the allowable number of times of writing in the non-volatile storage means 100 is immediately exceeded, and the useful life of the product is shortened. Since the number of times is at least 5, the service life of the product can be sufficiently secured.

In this embodiment, the operating state is sequentially stored in the nonvolatile storage means 100 during the operation. However, the operating state is stored in the nonvolatile storage means 100 when the power supply is interrupted. With the configuration, the same effect can be obtained.

Further, in this embodiment, only the step 128 is displayed when the previous operation has been interrupted. However, if the operation is not temporarily stopped, all the operations during the operation after the power is supplied again, or the power is supplied again. The same effect can be obtained even if an abnormality is displayed until after the operation is completed.

Further, the first to fourth embodiments are described as dishwashers and dryers, and in this embodiment, they are described as fully automatic washing machines. However, as an example of a large current consumption load,
Only a heater and a DC brushless motor were explained, a dishwasher was described as an example of a heater, and a fully automatic washing machine was described as an example of a DC brushless motor. The same applies to other appliances having a large current consumption load. The effect of can be expected.

(Embodiment 6) When the power supply to the control means 17 in FIG. 1 is started and the operation status stored in the non-volatile storage means 22 is in the middle of a series of operation operations of the equipment, the control means 17 The operation is restarted from the last stroke written in the nonvolatile storage means 22, and the current operation content is changed to the original operation content. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described with reference to FIGS. In FIG. 12, as in the first embodiment, in step 23, the user first supplies power by inserting a power plug into a power outlet or a breaker. In step 24, if there is no operation status data stored in the non-volatile storage unit 22, the control unit 17 determines that the operation has been completed normally last time, and in step 25, turns off the power. Then, it waits until the user presses the power switch 16a. Thereafter, steps 28 to 47 are performed in the same manner as in the first embodiment.

However, in step 24, control means 17
If there is operation status data stored in the non-volatile storage means 22, it is determined that the power supply was interrupted during the previous operation during the previous operation, and in step 48, the power is turned on according to the operation status data. , The course, the driving process, etc. are set again, and it is assumed in step 49 that the ambient temperature is 20 ° C. without inputting the ambient temperature from the thermistor 8.

At step 50, the notifying means 20
Is sounded to notify that the previous operation was interrupted. After that, in step 51, the device is set in a temporary stop state to wait for the device. At step 52, an abnormality display indicating that the operation was previously interrupted is displayed on the abnormality content display section,
In step 53, steps 52 to 53 are repeated until the user presses the start switch 16b.

At step 53, start switch 16b
Is pressed, in step 131, the operation is started again from the last step written in the nonvolatile storage means 22 at the time of the previous operation.

FIG. 13 shows the operation contents of step 131. In step 132, the driving situation data is determined,
If it is the data of the start, step 3
At 1, a water supply process is performed, and at step 133, a cleaning process is performed. At this time, the current consumption is halved by energizing only half of the heater 7. This is because the interruption of the power supply is considered to be caused by the breaker tripping due to the power supply to the heater 7, so that the breaker does not trip again.

Thereafter, the drainage process is performed in step 33, and when the drainage is completed, in step 34, the control means 1
7 writes the data indicating that the cleaning process has been completed in the nonvolatile storage means 22.

Next, at step 35, a water supply process is performed, and at step 36, a rinsing process is performed. At this time, similarly to the above-described cleaning process, the power supply to the heater 7 is limited to half, and the current consumption is also reduced to half. Thereafter, in step 37, a drainage process is performed. Then, in step 38, the control unit 17 writes data indicating that the first rinsing process has been completed in the nonvolatile storage unit 22. If necessary, repeat the water supply, rinsing and draining steps several times.

Next, in step 39, a water supply step of supplying fresh water or hot water is performed, and in step 40, a heating rinsing step is performed. At this time, similarly to the above-described cleaning process, the power supply to the heater 7 is limited to half, and the current consumption is also reduced to half.
Thereafter, in step 41, a drainage process is performed. And
At step 42, the control means 17
2 is written with data indicating that the heating and rinsing process has been completed.

Finally, in step 43, a drying process is performed.
At this time, similarly to the above-described cleaning process, the power supply to the heater 7 is limited to half, and the current consumption is also reduced to half. Then, in step 44, the control unit 17 deletes the data of the operation status stored in the nonvolatile storage unit 22. Thereafter, in step 45, the notification means 20 is sounded to notify the user of the end of driving.

Thereafter, in step 46, a dry keeping process is performed. After the end of the dry keeping process, the control means 17 turns off the power in step 47.

In step 132, the operation status data is determined. If the data is at the end of the cleaning process,
In step 35, a water supply process is performed, and thereafter, operation is performed in the same manner as when there is data at the start.

In step 132, the data of the driving situation is judged. If the data is the data at the end of the rinsing stroke, the water supply stroke is carried out in step 39, and then there is the data at the start. Similarly, drive the vehicle.

At step 132, the operation status data is determined. If the data is data at the end of the heating rinsing process, the drying process is performed at step 43, and then, when there is data at the start of the process. Driving is performed in the same manner as described above.

As described above, according to the present embodiment, when the power supply is interrupted during the operation, when the power is next supplied, the operation is changed from the previous operation so that the breaker is not turned off again. Can be.

In the present embodiment, the current consumption is halved by limiting the energization to the heater 7 to half, but the half is merely an example. The effect can be obtained. Also, the current is reduced by half, but this is also an example, and the same effect can be obtained even if the current is reduced by changing the conduction time such as phase control. Can be.

(Embodiment 7) As shown in FIG. 14, the interruption time measuring means 137 is incorporated in the control means 17 and measures the time during which the power supply is interrupted. It is determined based on the interruption time measured by the measuring means 137. Other configurations are the same as those of the sixth embodiment.

The operation of the above configuration will be described with reference to FIG. Although the cleaning process is performed in step 133 in FIG. 13 of the sixth embodiment, in the present embodiment,
This step will be described in detail.

At step 138 in FIG. 15, it is determined whether the mode is the low current mode. This is a mode in which the power failure of the heater 7 has been halved for three consecutive power outages even once. In other words, since the breaker is cut off when the entire heater 7 is energized, the current is limited so that the breaker does not cut off. If the current mode is not the low current mode, the number of power failures is determined in step 139. If three or more times in a row, step 140
To set the low current mode. This content is stored in the non-volatile storage means 22, and the low-current mode is set even if a power failure occurs.

Next, in step 141, only half of the heater 7 is energized to reduce the current consumed by the heater 7 by half.
This ensures that the breaker is not interrupted this time. If it is determined in step 139 that the time is less than three times in succession, in step 142, power is supplied to the entire heater, and the water temperature is rapidly increased.

Thereafter, in step 143, the interruption time is estimated. If the difference between the water temperature when the power supply is interrupted and the water temperature when the operation is restarted is 10 ° C. or more, it is determined that the interruption time is long, and in step 144, the operation time is extended by 10 minutes to 30 minutes. This is because there is a high possibility that the stains on the tableware are dried during the interruption time and the stains are difficult to remove.

If the difference in water temperature is less than 10 ° C., it is determined that the interruption time is short, and in step 145, the operation time is set to 20 minutes as usual.

Thereafter, in step 146, the pump is energized to perform cleaning. In step 147, it is determined whether or not the cleaning time has ended in the cleaning time. If not, the process returns to step 138 and the operation is repeated. If it has been completed, the process proceeds to the next step in step 148. If the current mode is the low current mode in step 138, the process proceeds to step 140, and the subsequent operation is performed.

As described above, according to the present embodiment, by limiting the current supplied to the heater 7 according to the number of continuous power failures, it is reliably detected that the breaker has been cut off by the operation of the equipment. Can be cut. Further, once the low-current mode is set, the low-current mode is stored, the current supplied to the heater 7 can be limited from the next time, and the breaker is hardly turned off. Also, by judging by the number of continuous power outages,
Even if the breaker is cut off by another device, the low current mode is not set, and the current supplied to the heater 7 is limited, so that the operation time can be prevented from becoming unnecessarily long.

In the present embodiment, the low current mode is set to the continuous power failure three times or more. However, the number of times the power failure is repeated three or more times is an example, and the same effect can be obtained with other times. Also, once the low-current mode is set, the low-current mode is set thereafter. However, it is not necessary to store the low-current mode, and the same effect can be expected without this function.

In the present embodiment, the power supply to the heater 7 is limited only at the time of recovery from the power failure. However, in the low current mode, even if the power supply to the heater 7 is limited during normal operation, the same applies. The effect of can be obtained.

Although the interruption time is estimated by the change in the water temperature, the same applies if the interruption time is directly measured by the control means or a means for measuring the interruption time is provided outside the control means. The effect can be expected.

Further, it is divided into two stages according to the interruption time,
The cleaning time was extended when the interruption time was long. However, the two-stage division and the extension of the cleaning time are merely examples, and similar effects can be expected by changing them. For example, in the case of a washing machine,
If the operation is interrupted during the washing process or the like, dirt removal proceeds as soaking washing during the interruption, so that the washing time can be shortened if the cold during the interruption is long.

Further, in this embodiment, the limitation of energization to the heater and the extension of the cleaning time have been described at the same time. However, the same effect can be obtained by using only one of them.

In this case, only the cleaning process is limited.
This is an example, and the same effect can be expected in other processes.

[0138]

As described above, according to the first aspect of the present invention, the non-volatile storage means in which the stored contents are not erased even when power is not supplied, and a series of operations of the device are sequentially controlled. Control means, the control means, while the series of operations of the device is operating, the operation status is appropriately stored in the non-volatile storage means, even if the power supply is interrupted, the control means It is possible to determine at what stage the last operation was interrupted, and when power is supplied again,
The operation can be continued from the interrupted stage.

According to the second aspect of the present invention, a nonvolatile storage means whose stored contents are not erased even when power is not supplied, a large current consuming load consuming a large current, and a series of operations of a device. Control means for sequentially controlling the device, after starting a series of operations of the device, before driving the large current consumption load, or between the driving of the large current consumption load, the appropriate Since the operating status is stored in the non-volatile storage means, even if the power supply is interrupted due to the operation of the equipment itself in the case of a device having a load that consumes a large current, the control unit determines at what stage the previous operation was performed. It can be determined whether or not the operation has been interrupted, and when power is supplied again, the operation can be continued from the interrupted stage.

According to the third aspect of the present invention, since the large current consumption load is a heater, in an apparatus having a heater, the control means reliably determines at which stage the previous operation was interrupted. Can be.

According to the fourth aspect of the present invention, since the large current consuming load is an inverter control type motor, in a device having an inverter control type motor consuming a large current, the control means is surely provided. It is possible to determine at which stage the previous operation was interrupted.

According to the fifth aspect of the present invention, when the operation status stored in the non-volatile storage means during the start of power supply to the control means is during a series of operation operations of the equipment, The control means restarts the operation from the last stroke written in the nonvolatile storage means. , It is possible to avoid using the detergent and water used before being interrupted again, and also to avoid wasting electric power without throwing away the heated water until then. . Further, even if the operation before the interruption was able to be returned by a human operation, it was necessary to check at what stage the interruption was performed, and a complicated operation was required. These operations can be reduced, and the operation before the interruption can be surely returned.

According to the sixth aspect of the present invention, the control means waits in a suspended state when restarting the operation from the last stroke written in the nonvolatile storage means. In the case where the operation is continued from the state where the previous operation was interrupted, it is possible to avoid giving the user unnecessary anxiety by waiting in the temporary stop state. Unnecessary anxiety is, for example, anxiety that an unintended operation of the user, such as suddenly starting to operate continuously from the state in which the previous operation was interrupted when the power supply is started, is performed without permission. It is.

According to the seventh aspect of the present invention, there is provided a notifying unit that emits a sound such as a buzzer, and when the power supply to the control unit is started, the operating state stored in the non-volatile storage unit is set to the device status. When the series of operation is in the middle of operation, the control means blows the notification means, so that the control means notifies the user with a buzzer or the like when the operation is continued from the state where the previous operation was interrupted. This makes it easier for the user to understand that the operation is continued. Also, if a power breaker located far from the equipment is turned on,
Since the user can also know that the power supply to the device has been started, the usability can be improved.

Further, according to the invention of claim 8, there is provided display means having a light emitting diode or the like, and when the power supply to the control means is started, the operation status stored in the non-volatile storage means is stored in a series of devices. When the operation was in the middle of operation, the control means displayed on the display means that the operation was interrupted.If the operation was continued from the state where the previous operation was interrupted, By displaying that continuation of operation is performed, the user can know that the operation is continued or that the operation is continued. In addition, when the operation is automatically continued, the series of operation time of the device is extended only for the time during which the power supply is interrupted or for a longer period of time. Therefore, it is possible to avoid a failure being determined despite normal operation.

According to the ninth aspect of the present invention, there is provided the temperature detecting means for detecting the temperature, and when the power supply to the control means is started, the operation status stored in the non-volatile storage means is stored in a series of devices. When the operation is in the middle of the operation, the control means replaces the input of the temperature detection means with a constant value, so that the temperature of the device can be prevented from being affected. For example, when detecting the temperature, the temperature and water temperature inside the device may have increased due to the previous operation, and the temperature detection may increase. in this case,
Although it is desired to detect the ambient temperature, there is a possibility that a temperature far from the ambient temperature may be detected, and by assuming the temperature to be a constant value, a sequence for securing a constant performance can be continued.

According to the tenth aspect of the present invention,
Since the water supply means and the drainage means are provided, and the process in which the control means writes the operation status in the nonvolatile storage means is at the time of completion of drainage,
The control means can continue the operation after the drainage is completed, and it is possible to prevent the control means from discarding the stored water or the hot water. In addition, if the sequential operation status is stored in every process, writing to the non-volatile storage means becomes a large number of times, and there is a danger that the reliability may not be maintained. The number of times can be reduced and the quality can be improved.

According to the eleventh aspect of the present invention,
