Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes control means for controlling the operation of equipment and nonvolatile storage means for storing equipment operation information, and the control means is based on equipment operation information stored in the storage means. The present invention relates to a device control device configured to control operation of a device.
[0002]
[Prior art]
In the device control apparatus having the above-described configuration, conventionally, for example, when there are a plurality of types of devices having different specifications such as the operation details of the devices, a control means for controlling the operation of the devices is provided for the plurality of types of devices. In order to use it in common, there was something configured as follows.
[0003]
In other words, in order to make it possible to determine the type of the device on which the device is mounted by the control unit, the type information as the device operation information readable by the control unit is used as an EEPROM as an example of a nonvolatile storage unit. There is one that is stored and prepared (for example, see Patent Document 1).
[0004]
In other words, the EEPROM as the nonvolatile storage means can write and store the information for operating the equipment as described above even after the control means is incorporated in the equipment. When the type information for identifying the type to the control unit is stored in the EEPROM, the control unit reads the type information and recognizes the type of the device. Control corresponding to the model can be performed. Then, after the device operation information is not written in the EEPROM, the device operation information is written and stored in the EEPROM after being incorporated in the device, or the device operation information is written and stored in the EEPROM. Since it is possible to perform control according to the device by incorporating it in any kind of device, it can be used in common regardless of the type of device. It is not necessary to prepare different things separately, and it is possible to reduce the cost.

[0006]
[Problems to be solved by the invention]
By the way, the EEPROM can perform information writing processing even after being incorporated into a device as described above, and can retain its stored contents even after power supply to the EEPROM is stopped. Because it is possible to retain the stored contents not only in the case of a power failure but also in the case where power supply is stopped by equipment operation stop operation to suppress power consumption, it is easy to use, It is often used for storing this kind of information.
[0007]
However, generally used EEPROM has a limited memory retention time (about 10 years) in which the memory state can be retained after information is written, and is written when this memory retention time elapses. Information will be volatilized. In addition, there is a limit to the number of times information can be written to the EEPROM, and if the writing process is performed exceeding the allowable number of times of writing (approximately 100,000 times), information may not be stored thereafter.
[0008]
When such an EEPROM is applied to a gas stove as an example of an apparatus, there are the following disadvantages.
In other words, in the case of a gas stove, the elapsed time from when the gas stove is installed at the place of use and set to a usable state until the gas stove is no longer used, such as being replaced or discarded, is the memory retention time. If the device operation information is written and stored using the EEPROM as described above, the elapsed time from the start of use of the gas stove exceeds the storage holdable time. Device operation information may volatilize and prevent normal operation.
[0009]
Therefore, in order to eliminate such disadvantages, in order to prevent the time that the EEPROM stores and holds information from exceeding the storage and holdable time, the device operation information is written to the EEPROM and the device is also stored. After being incorporated, it is conceivable to execute a process of rewriting the device operation information in the EEPROM, that is, a refresh operation.
However, gas stoves often use dry batteries as a power source. In order to reduce the power consumption of dry batteries, power is supplied to the equipment only when the gas stove is used, and power is supplied to the equipment when the gas stove is not used. Is configured to stop. Therefore, power is not supplied to the device unless the device is used, and if the power supply is stopped, the control means also does not operate. Therefore, each time power is supplied to the equipment, the control means It is conceivable to execute the refresh operation. In this way, when the processing for rewriting the device operation information to the EEPROM is performed every time power is supplied to the device in order to use the device, the number of times of writing to the EEPROM may vary depending on the device usage status. There is a possibility that the number of times of writing will be exceeded, and thereafter information cannot be stored in the EEPROM.
[0010]
As the nonvolatile storage means, the number of years that information can be stored and retained exceeds the storage and retention time (approximately 10 years), and the number of writes is greater than the allowable number of writes (approximately 100,000 times). There are special EEPROMs that guarantee the number of times, but such special EEPROMs are disadvantageous in that they are expensive and difficult to obtain.
[0011]
The present invention has been made paying attention to such a point, and the object thereof is to appropriately store device operation information while making it possible to use a convenient non-volatile storage means such as a general EEPROM. It is in the point which provides the apparatus control apparatus which becomes possible to keep.
[0012]
[Means for Solving the Problems]
The device control apparatus according to claim 1 is provided with a control unit that controls operation of the device and a non-volatile storage unit that stores device operation information, and the control unit is stored in the storage unit. The device is configured to control the operation of the device based on the device operation information,
The storage means comprises an operation information storage area for storing the equipment operation information, and a plurality of count value storage areas for storing count values,
Every time the control means reaches the count processing timing, any one of the plurality of count value storage areas in the storage means for which the stored count value does not reach the set target value is The count value stored in is added to or subtracted from the unit amount to be rewritten and stored as a new count value, and the setting condition for the refresh operation is satisfied based on the storage information in the plurality of count value storage areas If it is determined that it is a thing, it is configured to execute a refresh operation for rewriting the equipment operation information stored in the operation information storage area in the storage means.
[0013]
That is, the non-volatile storage means includes an operation information storage area for storing the device operation information and a plurality of count value storage areas for storing count values, and the control means is configured to perform counting processing timing. For each one of the plurality of count value storage areas in the storage means for which the stored count value does not reach the set target value, the stored count value is added to the unit amount. Alternatively, it is subtracted and rewritten into a new count value and stored. Therefore, every time the count processing timing comes, only one of the plurality of count value storage areas is rewritten with the count value, and the count value is stored in any one of the count value storage areas. When the count value reaches the set target value, the count value is rewritten in any other count value storage area where the count value does not reach the set target value.
[0014]
As the counting process timing, for example, the power supply from the power source is started to the device by the device operation start operation, and the power supply from the power source is stopped by the device operation stop operation. There is a configuration in which it is determined that the count processing timing is reached every time power supply is started. In addition to such a configuration, there is a configuration in which it is determined that the count processing timing is reached every time the usage time during which the device is used reaches a set time. In short, it is determined that the count processing timing has come when a predetermined condition that occurs periodically or irregularly as time elapses after the device is installed is satisfied.
[0015]
The control means repeatedly executes the rewrite processing of the count value for any one of the plurality of count value storage areas every time the count processing timing comes, and based on the storage information of the plurality of count value storage areas When it is determined that the setting conditions for the refresh operation are satisfied, a refresh operation for rewriting the device operation information stored in the operation information storage area in the storage means is executed.
[0016]
As setting conditions for the refresh operation, for example, there are cases where all the count values in the plurality of count value storage areas have reached the set target value. In addition to such a configuration, the count value may reach the set target value in any one of the plurality of count value storage areas.
[0017]
As a result, in each count value storage area, the count value is repeatedly rewritten and stored, so that the state in which the count value is not rewritten does not continue for a long time, for example, a time longer than the storage holdable time in the EEPROM. The number of times of writing to one count value storage area does not exceed the set target value. In the operation information storage area, when the setting conditions for the refresh operation are satisfied, the stored device operation information is rewritten, so that the state where the information is not rewritten is longer, for example, the storage retention time in the EEPROM Will not continue for a long period of time and will not be written to the operation information storage area until the refresh operation setting conditions are satisfied. For example, the number of times of writing to the information storage area can be suppressed to a number smaller than the allowable number of times of writing to the EEPROM.
[0018]
Therefore, in each of the plurality of count value storage areas and the operation information storage area, the state in which the stored information is not rewritten does not continue for a time longer than the storage holdable time in the EEPROM, and the number of times of writing is reduced. Since it is possible to suppress the number of times of writing to the EEPROM to be less than the allowable number of times of writing, it is possible to appropriately use the device operation information while making it possible to use an easy-to-use nonvolatile storage means such as a general EEPROM. It has come to be possible to provide a device control device that can be memorized.
[0019]
According to a second aspect of the present invention, there is provided the device control apparatus according to the first aspect, wherein the storage unit is configured to store identification information for model determination as the device operation information, and the control unit includes a plurality of types of devices. The operation of the device is controlled based on the device control information corresponding to the identification information for model determination stored in the storage unit among the plurality of device control information provided in a state corresponding to each of It is comprised as follows.
[0020]
That is, the storage means stores identification information for model determination as the device operation information, and the control means stores the plurality of device control information provided in a state corresponding to each of the plurality of types of devices. The operation of the device is controlled based on the device control information corresponding to the identification information for model discrimination stored in the means.
Accordingly, after the identification information for identifying the model is not written, the identification information for identifying the model is written and stored in the storage means after being incorporated in the device, or the identification information for identifying the model is stored in the storage means. By incorporating it into the device after writing and storing it, it is possible to perform control according to the device, but it can be shared with each of a plurality of types of devices, and it can be used for a plurality of types of devices. On the other hand, it is not necessary to provide different specifications for each, and the cost can be reduced.
[0021]
The device control apparatus according to claim 3 is configured such that the storage unit stores information for device control to be executed by the control unit as the device operation information in claim 1, and the control unit includes: The operation of the device is controlled based on the device control information stored in the storage means.
[0022]
That is, the storage means stores device control information to be executed by the control means, and the control means controls the operation of the equipment based on the device control information stored in the storage means. Therefore, the device control information is written and stored in the storage means after being incorporated in the device in a state where the device control information is not written, or the device control information is written and stored in the storage means. It is possible to perform control according to the device, but it can be shared for each of a plurality of types of devices, and each of the plurality of types of devices is different for each. It is not necessary to provide a specification and cost can be reduced. In addition, it is not necessary to provide all of a plurality of pieces of device control information corresponding to each of a plurality of types of devices, and there is an advantage that the configuration is simplified compared to storing all of them.
[0023]
The device control device according to claim 4 is provided with a dry battery as a power source of the device according to any one of claims 1 to 3, and power supply from the dry battery to the device is started by the device operation start operation. The power supply from the dry cell is stopped by the operation to stop the operation, and the control means determines that the count processing timing is reached every time the power supply from the dry cell is started. It is comprised by these.
[0024]
In other words, a dry battery is provided as a power source for the device, power supply from the dry battery to the device is started by the device operation start operation, and power supply from the dry battery is stopped by the device operation stop operation. The control means controls the operation of the device when the power supply is started, and stops the operation control of the device when the power supply is stopped. In this way, power is supplied only when the device is operated, and power is not consumed wastefully when the device is not operated. Therefore, the power consumption of the dry battery can be reduced as much as possible to extend the usable period.
[0025]
Each time power supply from the dry battery is started, it is determined that the counting process timing has come, and the count value rewriting process as described above is performed on any count value storage area. become. Such a count value rewrite process is repeatedly executed every time the count process timing is reached, and when the setting conditions for the refresh operation are satisfied, a refresh operation for rewriting the device operation information is executed. The number of times of writing to the operation information storage area can be suppressed to a number smaller than the allowable number of times of writing to the EEPROM, for example.
[0026]
Therefore, even when used in a device that supplies power using a dry battery, it is possible to use an easy-to-use non-volatile storage means such as a general EEPROM, while appropriately storing device operation information. It becomes possible to leave.
[0027]
The device control apparatus according to claim 5 is the device control device according to any one of claims 1 to 4, wherein the control unit refreshes the display when all the count values in the plurality of count value storage areas have reached the set target value. It is configured to discriminate that the setting condition for operation is satisfied, and is configured to rewrite and store all count values in the plurality of count value storage areas to zero. .
[0028]
That is, when all the count values in the plurality of count value storage areas reach the set target value, it is determined that the setting condition for the refresh operation is satisfied, and all the count values in the plurality of count value storage areas are Since the count value is rewritten to zero, until the set condition for the refresh operation is satisfied next time, the count value of the count value is again reached in each of the plurality of count value storage areas until all the count values reach the set target value. A rewriting process is performed. In this way, the refresh operation can be executed every time the count value rewrite processing reaches the set number of times, and the state in which the information stored in the storage means is not rewritten is longer than the storage holdable time in the EEPROM. In addition, the number of times of writing is not continued and the number of times of writing can be suppressed to a number smaller than the allowable number of times of writing to the EEPROM.
[0029]
A device control apparatus according to a sixth aspect is characterized in that in any one of the first to fifth aspects, the device is a gas stove.
[0030]
In other words, it is possible to reduce the cost of the gas stove by using the same for a plurality of types of gas stoves, without having to prepare different device control devices for each of the plurality of models. For device operation such as identification information for identifying the type of the gas stove and information for controlling the device to be executed in that model while making it possible to use an easy-to-use non-volatile storage means such as an EEPROM It became possible to memorize information appropriately.
[0031]

The upper and lower sides of the portion to be cooked are composed of a double-sided burner having a planar upper surface burner GB1 and two lower surface burners GB2 and GB3 so that the front and back surfaces can be cooked simultaneously. Spark plugs P3 and P4 are provided in the ignition pilot GP and the lower burner GB2 far from the grill ignition pilot GP, respectively, and the thermocouple T3 for detecting the burner combustion state and abnormal heating of the grill water pan are performed. A grill overheat prevention sensor ST2 for detection is also provided. At the time of ignition, the ignition plug P3 ignites the grill ignition pilot GP. The fire ignites the upper burner GB1 and the lower burner GB3, and at the same time, the lower plug burner GB2 is ignited by the ignition plug P4. The combustion state is detected by a thermocouple T3 that detects the combustion state. The configuration of the safety valve V4, the point-extinguishing operation tool S3, the needle valve M3 for adjusting the flow rate, and the like other than those configurations are the same as those for the first stove unit C1, and the point-extinguishing operation unit S3 is pushed. Thus, an ignition operation and a valve opening operation are performed, and gas combustion as described above is started.
[0037]
As shown in FIG. 2, the mode setting unit MS provided on the front panel has a frying key 2 for instructing a frying operation for heating fried oil and cooking fried food such as tempura, and a watering key for instructing a kettle operation. 3. Rice cooking key 4 for instructing rice cooking operation for cooking rice or rice porridge, fried food display lamp 5 indicating that it is in the fried food operation state and that the set temperature is 160 ° C, 180 ° C, 200 ° C in the fried food operation There are provided a water heater lamp 6 indicating that the water heater operation is being performed, a rice cooking lamp 7 indicating whether the rice cooking operation state is “rice porridge” or “rice”, and the like.
[0038]
Each of the point fire extinguishing operation tools S1, S2, and S3 is held in the combustion operation position when the hand is released after pushing from the fire extinguishing position protruding outward from the front panel portion to the ignition position. It is configured to return to the fire extinguishing position when operated and released. Switches 8, 9, 10 that switch to the on state in accordance with the push operations of the respective point fire extinguishing operation tools S 1, S 2, S 3 are provided separately, and are operated to the combustion operation position and the ignition position. Sometimes, the corresponding switch is turned on, and the switch is turned off when the point fire extinguishing operation tool S1 is in the fire extinguishing position. These switches 8, 9, and 10 are for switching between a state in which power from the dry battery BT as a power source is supplied to the control unit H and a state in which the supply is stopped.
[0039]
That is, as shown in FIG. 4, the control unit H includes a microcomputer 11 as a control unit for controlling the operation of each unit and a power switch unit 12 for supplying power to the microcomputer 11. Provided, when any of the switches 8, 9, 10 is turned on, the switching transistor 13 in the power switch section 12 is turned on to switch to a state of supplying power to the microcomputer 11, and when the switch is turned off, The switching transistor 13 is turned off and the power supply to the microcomputer 11 is stopped.
[0040]
The control unit H is configured to execute temperature control control and overheat prevention control for the second stove unit C2. Explaining this temperature control and overheat prevention control, if the frying operation is commanded by the mode setting unit MS, the bottom surface temperature of the heated object such as a pan detected by the temperature sensor ST1 is 160 ° C, 180 ° C. When it is detected that any one of the set temperatures of 200 ° C. is reached, the solenoid valve V2 is closed to suppress the fuel supply amount to make a small fire, and the solenoid valve V2 is opened to restore the original temperature. The process of maintaining the temperature almost at the preset temperature is repeated. When a water heater operation is commanded, when the bottom temperature of the heated object such as a pan detected by the temperature sensor ST1 reaches the boiling temperature (about 100 ° C.), the solenoid valve V2 is closed to suppress the fuel supply amount. Then, a process of automatically extinguishing fire is executed after 5 minutes. In addition, when the rice cooking operation is commanded with the heating power adjustment lever RE adjusted to the position for cooking rice, a process of controlling the combustion state so that it becomes a heating state set for cooking rice and automatically extinguishing when cooking is completed is performed. Execute. Even in the state where any operation as described above is not instructed, when the bottom surface temperature of a heated object such as a pan detected by the temperature sensor ST1 reaches 250 ° C., it is determined that cooking is performed using oil. Then, the state in which the solenoid valve V2 is closed to suppress the fuel supply amount to make a small fire and the state in which the solenoid valve V2 is opened to the original heating power is repeatedly maintained at about 250 ° C. And if this state continues for 30 minutes, it will be considered that it has forgotten to put out and the process which carries out automatic fire extinguishing is performed.
[0041]
Further, when the elapsed time during which the burner continuously burns in the stove part C2 and the grill cooking part G reaches the set time, the control part H executes timer automatic fire extinguishing control for controlling the operation of the safety valves V3 and V4. It is configured as follows. This automatic timer fire extinguishing control will be explained. As for the stove part C2, when the continuous combustion time after starting the burner reaches 2 hours, the safety valve V3 is shut off to stop the fuel supply and stop the combustion. Let In addition, the grill cooking unit G is configured to stop the combustion by stopping the fuel supply by shutting off the safety valve V4 when the continuous combustion time after starting the burner combustion reaches 15 minutes.
[0042]
The gas stove includes an EEPROM 14 which is an example of a nonvolatile storage means for storing identification information for model discrimination as device operation information, and the microcomputer 11 corresponds to each of a plurality of types of gas stoves. The operation of the gas stove is controlled based on the device control information corresponding to the identification information for model discrimination stored in the EEPROM 14 among the plurality of device control information provided in the state to be performed.
[0043]
In other words, the microcomputer 11 stores in advance a plurality of device control information SD1 to SDn corresponding to a plurality of types of gas stoves having different specifications in a non-volatile memory 11a composed of its own mask ROM. The control can be executed by setting any one of them. Further, in the EEPROM 14, identification information for identifying a model for identifying which type of gas stove among a plurality of types is written and stored in advance.
Accordingly, the microcomputer 11 reads the identification information for model discrimination stored in the EEPROM 14, sets the device control information for the corresponding model, and executes control. That is, this microcomputer 11 can be used in common for a plurality of types of gas stoves.
[0044]
Examples of gas stoves with different specifications include, for example, those having different specifications of the set temperatures when performing the overheat prevention operation or those having a function of executing such an overheat prevention operation There are those that do not have, those that have a display lamp that indicates the combustion state, and those that do not.
[0045]
As shown in FIG. 5, the EEPROM 14 includes an operation information storage area A for storing the identification information for identifying the model, and a plurality of count value storage areas B1 to Bn for storing count values. Each time the microcomputer 11 determines that the count processing timing is reached, specifically, every time when the power supply from the dry battery BT is started, the microcomputer 11 determines that the count processing timing is reached. For any one of the plurality of count value storage areas B1 to Bn in which the stored count value does not reach the set target value, the stored count value is incremented by a unit amount to newly Rewrite and store the correct count value. Further, if it is determined that the setting condition for the refresh operation is satisfied based on the storage information in the plurality of count value storage areas, specifically, all the count values in the plurality of count value storage areas B1 to Bn are stored. When it is determined that the set target value has been reached, a refresh operation is performed to rewrite the identification information for model determination stored in the operation information storage area A of the EEPROM 14.
[0046]
A specific control operation of the microcomputer 11 will be described based on a flowchart.
As shown in FIG. 6, when any one of the point fire extinguishing operation tools S 1, S 2, S 3 is pushed and energization of the microcomputer 11 is started, the operation information storage area A in the EEPROM 14 is stored in the operation information storage area A. The stored model discrimination data HD as the identification information for model discrimination is read (steps 1 and 2), and all count values in the plurality of count value storage areas B1 to Bn are read (step 3). These count values are initially set to zero when the gas stove is shipped from the factory.
[0047]
Next, the count value stored in a predetermined order for the plurality of count value storage areas B1 to Bn is an upper limit value KD as a set target value. _MAX Whether or not the count value is the set target value KD _MAX If the count value has not been reached, the count value stored in the count value storage area is added to the unit amount and rewritten and stored as a new count value. That is, the count value KD1 stored in the first count value storage area B1 is the set target value KD. _MAX If not reached, the count value KD1 stored in the count value storage area B1 is incremented by a unit amount (+1) and rewritten and stored as a new count value (steps 4, 5, and 6). The count value KD1 in the first count value storage area B1 is the set target value KD. _MAX If it has reached, the same processing is executed for the second count value storage area B2 (steps 9, 10, and 11). Thereafter, the count value KD1 is similarly set to the set target value KD. _MAX For those not reached, the above-described rewrite processing of the count value is sequentially performed for the plurality of count value storage areas B1 to Bn (steps 4, 9, 12, 13, and 14).
[0048]
Then, after executing such a count value rewriting process, the type of the gas stove is determined based on the model determination data HD read from the operation information storage area A, and is written and stored in the memory in advance. Set the information corresponding to the model from the multiple device control information corresponding to multiple types of gas stove, and control the gas stove until energization is stopped, that is, overheat prevention control and timer automatic fire extinguishing control as described above, etc. (Steps 7 and 8).
[0049]
When energization is started and the count value rewrite process as described above is executed, all the count values KD1 to KDn in the plurality of count value storage areas B1 to Bn are set target values KD. _MAX If it has reached, it is determined that the setting condition for the refresh operation is satisfied, and all count values in the plurality of count value storage areas are rewritten to zero and stored (step 15). A refresh operation for rewriting and storing the model discrimination data HD stored in A is executed (step 16).
[0050]
Thus, the state in which the stored information is not rewritten in each of the plurality of storage areas in the EEPROM 14, that is, the operation information storage area A and the plurality of count value storage areas B1 to Bn, is stored in the EEPROM 14. It does not continue for a longer time than the possible time (about 10 years), and the number of times of writing can be suppressed to a number less than the allowable number of times of writing to the EEPROM 14 (about 100,000 times).
[0051]
[Second Embodiment]
Hereinafter, 2nd Embodiment of the apparatus control apparatus which concerns on this invention is described based on drawing.
In this embodiment, the control configuration in the microcomputer 11 and other configurations other than the information stored in the EEPROM 14 are the same as those in the first embodiment, so only the different configuration will be described, and the same configuration will not be described. Omitted.
[0052]
That is, in this embodiment, the EEPROM 14 as the storage means does not store the identification information for model determination as the equipment operation information, but stores the equipment control information to be executed by the microcomputer 11 as the control means. The microcomputer 11 is configured to control the operation of the device based on the device control information stored in the EEPROM 14. When the microcomputer 11 determines that the setting condition for the refresh operation is satisfied, the microcomputer 11 executes a refresh operation for rewriting the device control information stored in the EEPROM 14.
[0053]

[Another embodiment]
Hereinafter, other embodiments are listed.
[0057]
(1) In each of the above-described embodiments, every time the count processing timing comes, any one of the plurality of count value storage areas is incremented by the unit value of the count value stored therein and rewritten and stored. However, instead of such a configuration, the following configuration may be used.
A predetermined value may be stored in advance as an initial value of the count value, and the count value may be subtracted by a unit amount every time the count processing timing is reached and stored. In this case, when all the count values become zero, it can be determined that the setting condition for the refresh operation is satisfied.
[0058]
(2) In each of the above embodiments, when all the count values in the plurality of count value storage areas reach the set target value, it is determined that the setting condition for the refresh operation is satisfied. In addition, an example is shown in which all the count values in the plurality of count value storage areas are rewritten to be stored as zero, but may be configured as follows instead of such a configuration. Good.
[0059]
For example, not all the count values in a plurality of count value storage areas have reached the set target value, but the count value of any one of the plurality of count value storage areas is When the set target value is reached, it may be determined that the setting condition for the refresh operation is satisfied.
[0060]
Also, as described above, every time the count processing timing is reached, the count value is repeatedly added, and when all count values have reached the set target value, all count values in a plurality of count value storage areas are set to zero. Then, every time the counting process timing is reached, a process of subtracting the count value of any one of them from the set target value by a unit amount is performed. When the count value becomes zero, it may be determined that the setting condition for the next refresh operation is satisfied.
[0061]
(3) In each of the above embodiments, the EEPROM is used as the nonvolatile storage means. However, any nonvolatile storage means that can be electrically written and erased may be used, and other storage means are used instead of the EEPROM. Also good.
[0062]
(4) In each of the above embodiments, a dry battery is provided as a power source for the device, power supply from the dry battery is started to the device by the device operation start operation, and power supply from the dry battery is performed by the device operation stop operation. It is configured to be stopped, and each time the power supply from the dry battery is started, it is exemplified that it is determined that the counting processing timing has been reached, but instead of such a configuration, the following configuration is configured. May be.
You may make it use AC100V commercial power supply as a power supply of an apparatus.
In addition, the counting processing timing is implemented in various forms, such as being configured to determine that the counting processing timing has been reached each time the period during which the device is used reaches a preset time. May be.
[0063]
(5) In each of the embodiments described above, an example in which the device according to the present invention is adapted to a table type gas stove has been shown. However, the present invention can also be applied to a built-in type gas stove, and is not limited to a gas stove. A control means for controlling the operation and a non-volatile storage means for storing the equipment operation information are provided, and the control means controls the operation of the equipment based on the equipment operation information stored in the storage means. As long as it is configured as described above, it can be applied to various devices.
