  A battery replacement sign 53 is provided on the lower left side of the operation panel section 22. As will be described later, when the battery voltage of the battery 26 stored in the battery case 14 falls below a predetermined threshold value (for example, 2.2 V), the battery replacement sign 53 lights up. An ignition confirmation lamp 55 for the left stove burner 5 is provided in a lower right portion of the operation panel section 22 and immediately above the operation button 13. When the left stove-burner 5 is ignited, the ignition confirmation lamp 55 is turned on, and when the left stove-burner 5 is extinguished, the ignition confirmation lamp 55 is turned off.

  The electrical configuration of the stove 1 will be described with reference to FIG. The stove 1 includes a control circuit 70. The control circuit 70 includes an I / O interface (not shown) in addition to a CPU 71, a ROM 72, a RAM 73, a flash memory 74, and a timer 75. The CPU 71 generally controls various operations of the stove 1. The ROM 72 stores various programs including an ignition control program. The ignition control program is for executing an ignition control process (see FIG. 6) described later. The RAM 73 temporarily stores various information. The flash memory 74 is nonvolatile and stores various data including an ignition restriction table 741 (see FIG. 5) described later. The timer 75 is operated by a program.

  The control circuit 70 includes a power supply circuit 120, a switch input circuit 121, a panel control circuit 122, an audio output circuit 123, an LED driver circuit 124, a thermistor input circuit 125, a misfire detection circuit 126, a safety valve circuit 127, a solenoid valve circuit 128, and an igniter. The circuit 129 and the like are connected.

  The board input 18 and the igniter switch 19 are connected to the switch input circuit 121. The board switch 18 is turned on / off in conjunction with the operation of the corresponding operation buttons 11 to 13. The switch input circuit 121 detects the state of the board switch 18 and inputs the state to the power supply circuit 120 and the control circuit 70. The igniter switch 19 is turned on after the board switch 18 is turned on in the process of pressing the corresponding operation button 11 to 13, and is turned off in the process of pushing back the operation button 11 to 13. It turns off earlier. The switch input circuit 121 detects the state of the igniter switch 19 and inputs it to the control circuit 70.

  The power supply circuit 120 supplies power supplied from the battery 26 housed in the battery case 14 to various circuits when the board switch 18 of any of the operation buttons 11 to 13 is turned on. The control circuit 70 operates when power is supplied from the power supply circuit 120, and stops operating when power supply is interrupted. Further, a voltage measuring unit 27 is connected to the positive and negative electrode sides of the battery 26. The voltage measurement unit 27 receives a control command from the control circuit 70, measures the output voltage of the battery 26, and inputs the measurement result to the control circuit 70 as a measurement signal.

  The various switches, the display unit, the LEDs, and the like provided on the operation panel units 21 and 22 are connected to the panel control circuit 122. The panel control circuit 122 detects that various switches provided on the operation panel units 21 and 22 are pressed, and inputs the detection to the control circuit 70. Further, the panel control circuit 122 receives a control command from the control circuit 70, and controls display on the display unit, lighting and blinking of the LED, and the like. The sound output circuit 123 receives a control command from the control circuit 70 and controls sound output from the speaker 25 provided in the housing 2. The LED driver circuit 124 receives a control command from the control circuit 70, and controls turning on and off of the battery exchange sign 53.

  The thermistor input circuit 125 inputs the detection signal of the thermistor 65 to the control circuit 70. The misfire detection circuit 126 detects a misfire of the right and left stove burners 4 and 5 based on the thermoelectromotive force generated by the thermocouple 66 and inputs the misfire to the control circuit 70. The safety valve circuit 127 receives a control command from the control circuit 70 and controls the energization of the safety valve 67. The safety valve 67 is provided on three gas supply pipes (not shown) that supply gas to each of the right stove burner 4, the left stove burner 5, and the grill burner. The safety valve 67 is a magnet-type safety valve, and is mechanically opened by the pressing operation of the operation buttons 11 to 13 to be in an open state. The safety valve circuit 127 receives a control command from the control circuit 70 and energizes the safety valve 67. The safety valve 67 maintains the open state. For example, when the right stove burner 4 misfires, the thermoelectromotive force generated in the thermocouple 66 is lost, so that the misfire detection circuit 126 inputs a misfire signal of the right stove burner 4 to the control circuit 70. The safety valve circuit 127 receives a control command from the control circuit 70 and cuts off the power supply to the safety valve 67. Thus, the safety valve 67 is closed by the urging force of a spring (not shown).

  The electromagnetic valve circuit 128 opens and closes the gas amount adjusting electromagnetic valve 68 based on the control of the CPU 71. The solenoid valve 68 is a gas shut-off solenoid valve. The solenoid valve 68 is provided, for example, in a bypass pipe (not shown) that branches off from the middle of the gas supply pipe and merges again. By opening and closing the solenoid valve 68, the flow path of the bypass pipe is opened and closed, and the amount of gas supplied to the burner increases and decreases. As a result, the burner power can be adjusted to two levels, high heat and low heat. The igniter circuit 129 receives a control command from the control circuit 70 and drives the igniter 69.

  The ignition restriction table 741 will be described with reference to FIG. In the first embodiment, when the battery voltage falls below a predetermined threshold, the burner that can be ignited is limited to a specific burner in addition to turning on the battery replacement sign 53. As a result, the user is strongly encouraged to replace the battery, and minimal cooking is possible even before the battery is replaced. The ignition restriction table 741 sets presence or absence of ignition restriction for the right stove burner 4, the left stove burner 5, and the grill burner. In the present embodiment, for example, the left stove burner 5 and the grill burner are set to have an ignition limit, and the right stove burner 4 is set to have no ignition limit. That is, the right burner 4 is set to the specific burner.

  The ignition control process will be described with reference to FIG. When the user presses any one of the operation buttons 11 to 13 and the corresponding board switch 18 is turned on, the CPU 71 reads out the ignition control program from the ROM 72 and executes this processing. For example, when the operation button 13 is pressed, a main valve (not shown) and a safety valve 67 provided in a gas supply pipe of the corresponding left stove burner 5 are forcibly opened, and gas flows into the left stove burner 5. The main valve maintains an open state in conjunction with the depression of the operation button by a well-known push / push mechanism.

  When the board switch 18 corresponding to the pressed operation button 13 is turned on, the CPU 71 recognizes the pressed operation button 13 and energizes the safety valve 67 provided in the gas supply pipe of the left stove burner 5 (S1). ). As a result, the safety valve 67 maintains the open state. In a state where the gas is supplied to the flame hole of the left stove burner 5, the CPU 71 turns on the igniter 69 (S2), and executes the ignition operation for the left stove burner 5. At this time, the CPU 71 measures the battery voltage by the voltage measurement unit 27, and determines whether the measured battery voltage is 2.2 V or more (S3). Hereinafter, description will be made in order of scenes (1) to (3).

(1) When the battery voltage at the time of ignition of the left stove burner 5 is 2.2 V or more When the battery voltage is 2.2 V or more (S3: YES), the CPU 71 closes the safety valve 67 because the remaining battery power is sufficient. The operation of the igniter 69 is continued, and the ignition of the left stove burner 5 is completed (S7). The CPU 71 starts normal control of the left stove burner 5 (S8).

  In the normal control, the CPU 71 determines whether or not the operation button 13 is pressed again and the burning burner is extinguished (S12). If the fire has not been extinguished (S12: NO), the CPU 71 determines whether or not the battery voltage is 2.2 V or more (S14). When the battery voltage is equal to or higher than 2.2 V (S14: YES), the CPU 71 returns to S8 and continues the normal control. On the other hand, when the battery voltage is less than 2.2 V (S14: NO), the CPU 71 turns on the battery replacement sign 53 (S15) and prompts the user to replace the battery. The CPU 71 returns to S8 and continues the normal control.

  When the operation button 13 is pressed again to extinguish the left stove burner 5, the main valve is closed by the push-push mechanism, and the gas supply to the burner is shut off. 5 is extinguished (S12: YES). When the operation button 13 is pressed again, the board switch 18 is turned off, so that the CPU 71 turns off the power supply to the safety valve 67 (S13). As a result, the safety valve 67 is also closed, and the CPU 71 ends this processing. When the battery voltage at the time of ignition of the right stove burner 4 is 2.2 V or more, the CPU 71 executes the same processing as that at the time of ignition of the left stove burner 5.

(2) When the battery voltage at the time of ignition of the left stove burner 5 is less than 2.2 V When the battery voltage is less than 2.2 V (S3: NO), it is desirable to replace the battery promptly because the remaining battery level is small. . Then, the CPU 71 turns on the battery replacement sign 53 (S4), and urges the user to replace the battery. Further, the CPU 71 determines whether or not there is an ignition restriction on the left stove burner 5 based on the ignition restriction table 741 (see FIG. 5) (S5). Since the left stove burner 5 is set to have ignition restriction (S5: NO), the CPU 71 turns off the igniter 69 (S9) and turns off the power supply to the safety valve 67 (S10). Thereby, before the ignition of the left stove-burner 5 is completed, the gas supply to the left stove-burner 5 is cut off, so that the ignition of the left stove-burner 5 is limited.

  Further, the CPU 71 outputs a message indicating that the battery cannot be ignited due to a low battery voltage from the speaker 25 by voice (S11). For example, a sound such as "Ignition cannot be performed due to low battery voltage. Please replace the battery promptly" may be output. Thereby, even if the user does not notice the lighting of the battery replacement sign 53, the user feels inconvenience that the left stove burner 5 to be used cannot be ignited, and thus the awareness of battery replacement is enhanced. be able to. In addition, the fact that the ignition has been restricted due to the decrease in the battery voltage can be notified by voice, so that the user can know exactly why the left stove burner 5 could not be ignited. Thus, the CPU 71 ends this processing.

(3) When the battery voltage at the time of ignition of the right stove 4 is less than 2.2 V, when the operation button 12 is pressed and the battery voltage is less than 2.2 V (S3: NO), the CPU 71 The battery exchange sign 53 is turned on (S4) to urge the user to replace the battery. Further, the CPU 71 determines whether or not there is an ignition restriction on the right stove burner 4 based on the ignition restriction table 741 (S5). Since the right stove burner 4 is set to have no ignition restriction (S5: YES), the CPU 71 subsequently determines whether or not the battery voltage is 2.1 V or higher (S6).

  Here, even when the battery voltage is less than 2.2 V, if the battery voltage is 2.1 V or more (S6: YES), the battery 26 is not completely cut off immediately, and at least the current cooking is finished without any problem. Since the voltage can be applied, the CPU 71 proceeds to S7, completes the ignition of the right stove burner 4, and executes the normal control (S8). This allows the user to replace the battery after the current cooking is completed, so that the stove 1 can be improved in usability. Further, in the present embodiment, when a decrease in the battery voltage is detected, only the right stove burner 4 that is a high-heat burner is set to a specific burner that can be used. Even for objects, it can be handled by adjusting the heat power with a high heat burner. As a result, even if the battery voltage is reduced, heating can be performed for a while until the battery is replaced, so that usability can be improved.

  If the battery voltage at the time of ignition of the left stove burner 5 is less than 2.2 V as in the above (2), the left stove burner 5 cannot be used. By substituting, cooking can be performed. Since the right stove burner 4 is a high heat burner, it is possible to cope with cooking with a weak heat by adjusting the heat. However, only the right stove burner 4 can be used until the battery is replaced, so that the stove 1 can make the user more inconvenient than usual. Therefore, the stove 1 can increase the user's awareness of battery replacement.

  On the other hand, when the battery voltage is less than 2.1 V (S6: NO), even if the right stove burner 4 is ignited, the battery 26 is completely cut off during cooking and the stove 1 does not move at all. Therefore, the CPU 71 turns off the igniter 69 (S9) and turns off the power supply to the safety valve 67 (S10). As a result, before the ignition of the right stove burner 4 is completed, the gas supply to the right stove burner 4 is cut off, so that the ignition of the right stove burner 4 is limited.

  Further, the CPU 71 outputs a message indicating that the battery cannot be ignited due to a low battery voltage from the speaker 25 by voice (S11). For example, a sound such as "Ignition cannot be performed due to low battery voltage. Please replace the battery promptly" may be output. Thus, the user can recognize that the ignition of the right stove burner 4 has been limited due to the decrease in the battery voltage. Thus, the CPU 71 ends this processing.

  As described above, the stove 1 of the first embodiment is driven using the battery 26 as a power source. The voltage measuring unit 27 of the stove 1 detects the battery voltage of the battery 26. The CPU 71 of the stove 1 limits available burners among the right stove burner 4, the left stove burner 5, and the grill burner to specific burners according to the battery voltage detected by the voltage measuring unit 27. Thus, the stove 1 can make the user feel more inconvenient than in the normal case, and the consciousness of replacing the battery 26 can be enhanced. Further, by leaving usable burners, minimal cooking can be performed. Therefore, the present embodiment can provide a stove 1 that is easy to use.

  In the above-described embodiment, when the battery voltage becomes lower than the threshold, the battery replacement sign 53 is turned on to notify the user that it is time to replace the battery. In conjunction with this, the CPU 71 restricts usable burners to specific burners, so that the awareness of battery replacement can be increased.

  In the above embodiment, when the battery voltage becomes lower than the threshold value, the usable burners are limited to only the right stove burner 4 which is a high heat burner. Since the right stove burner 4 has a larger maximum heating power than the left stove burner 5, even if the use of the left stove burner 5 is restricted, the right stove burner 4 can adjust the heating power.

  In the above-described embodiment, even if the burner is accepted by the user pressing the operation button in a state in which the battery voltage is reduced and the usable burners are limited, the accepted burner ignition is limited. In this case, the CPU 71 notifies by voice that the use of the burner is restricted. Thus, it is possible to make the user strongly recognize that the use of the burner is restricted due to the decrease in the battery voltage.

  In the above description, the voltage measuring unit 27 is an example of the “remaining amount detecting unit” of the present invention. The CPU 71 executing the processing of S3 to S5, S9, and S10 in FIG. 6 is an example of the “part restriction unit” of the present invention. The CPU 71 executing the processes of S3 and S6 is an example of the “judgment unit” of the present invention. The CPU 71 executing the processing in S4 is an example of the “notifying unit” of the present invention. The right stove burner 4 is an example of the “first stove burner” of the present invention, and the left stove burner 5 is an example of the “second stove burner” of the present invention. The operation buttons 11 to 13 are an example of the “accepting unit” of the present invention. The CPU 71 executing the process in S11 is an example of the “usage restriction notifying unit” of the present invention.

  A second embodiment of the present invention will be described with reference to FIGS. As described above, in the stove 1 of the first embodiment, when a decrease in the battery voltage of the battery 26 is detected, the available burners are limited to a specific burner, thereby making the user more inconvenient than normal. And increase awareness of battery replacement. On the other hand, in the stove 1 of the second embodiment, when a decrease in the battery voltage of the battery 26 is detected, the functions that can be executed during the burner combustion are limited to a specific function, so that the user can be provided with a normal function. Makes you feel inconvenience and strongly recognizes battery replacement. Here, the “functions” that can be executed during burner combustion mean the various functions that can be set by various switches provided on the operation panel units 21 and 22.

  Note that the configuration of the stove 1 of the second embodiment is substantially the same as the configuration of the stove 1 of the first embodiment, and therefore, in the following description, the same reference numerals are used for the common parts. In addition, description of common parts will be omitted or simplified, and different parts will be mainly described.

  The stove 1 of the second embodiment stores a function restriction table 742 shown in FIG. 7 in the flash memory 74 instead of the ignition restriction table 741 shown in FIG. The function restriction table 742 indicates whether or not there is a function restriction for the stove timer selection switch 32, the "-" switch 34, the "+" switch 35, the high-temperature stir switch 41, the water heater switch 42, the temperature selection switch 44, and the rice cooker switch 51. Set each. The stove timer selection switch 32, the "-" switch 34, and the "+" switch 35 are function switches for setting a timer function (a stove timer, a grill timer). The high-temperature fry switch 41 is a function switch for setting the high-temperature fry function. The water heater switch 42 is a function switch for setting a water heater function. The temperature selection switch 44 is a function switch for setting a temperature keeping function. The rice cooking switch 51 is a function switch for setting a rice cooking function. The temperature keeping function is an example of the “temperature adjusting function” of the present invention.

  In the present embodiment, for example, there is no function restriction on the stove timer selection switch 32, the “-” switch 34, the “+” switch 35, and the temperature selection switch 44, and the high-temperature stir switch 41, the water heater switch 42, and the rice cooker switch 51 Is set to have function restrictions. That is, when the battery voltage is reduced, the functions are limited to the high-temperature stir function, the boiling water function, and the rice cooking function, and the specific functions whose functions are not limited are the timer function and the temperature keeping function.

  Note that the presence or absence of the function limitation is not limited to the setting of the function limitation table 742 shown in FIG. 7, but is particularly related to safety, such as timer cooking often used when cooking oil or temperature keeping function. Preferably, the functions are not restricted.

  The combustion control process will be described with reference to FIG. When the user presses any one of the operation buttons 11 to 13 and the corresponding board switch 18 is turned on, the CPU 71 reads out the combustion control program from the ROM 72 and executes this processing. Steps S21 and S22 are the same as steps S1 and S2 in FIG. For example, when the operation button 12 is pressed, the CPU 71 turns on the corresponding igniter 69 (S22) and ignites the right stove burner 4 (S23). The CPU 71 starts normal control of the right stove burner 4 (S24).

  The CPU 71 measures the battery voltage by the voltage measurement unit 27, and determines whether the measured battery voltage is 2.2 V or more (S25). If the battery voltage is equal to or higher than 2.2 V (S25: YES), the battery voltage is sufficient, and the CPU 71 proceeds directly to S27. On the other hand, if the battery voltage is less than 2.2 V (S25: NO), the CPU 71 turns on the battery replacement sign 53 (S26), prompts the user to replace the battery, and proceeds to S27.

  During the normal control of the right stove burner 4, the CPU 71 determines whether any of the function switches has been pressed (S27). If none of the function switches has been pressed (S27: NO), the CPU 71 determines whether or not the burning right stove burner 4 has been extinguished (S35). If the fire has been extinguished (S35: YES), the CPU 71 cuts off the energization of the corresponding safety valve 67, and ends this processing. If the fire has not yet been extinguished (S35: NO), the CPU 71 returns to S25 and repeats the process.

-When the high temperature stir switch 41 is pressed-
For example, when the user presses the high-temperature fry switch 41 to set the high-temperature fry function during the normal control of the right stove burner 4 (S27: YES), the CPU 71 determines whether the battery voltage is 2.2 V or more. It is determined whether or not (S28). Here, if the battery voltage is 2.2 V or more (S28: YES), the battery voltage is sufficient, and the high-temperature stir-fry function is executed (S32).

  On the other hand, if the battery voltage is less than 2.2 V (S28: NO), the CPU 71 turns on the battery replacement sign 53 (S29) and determines whether or not there is a functional restriction on the high-temperature stir function corresponding to the high-temperature stir switch 41. Is determined (S30). Referring to the function restriction table 742 (see FIG. 7), the function restriction is set to exist for the high-temperature stir fry function. Therefore, the CPU 71 does not execute the high-temperature stir-fried function, and notifies by voice a message indicating that the function cannot be executed due to a decrease in the battery voltage (S33).

  In this case, for example, a sound such as "The high-temperature stir-fry function cannot be executed due to a low battery voltage. Please replace the battery promptly." Thereby, even if the user does not notice the lighting of the battery exchange sign 53, the user feels inconvenience that the high temperature stir-fry function cannot be used, so that the awareness of battery exchange can be enhanced. In addition, the fact that the function has been limited due to the decrease in the battery voltage can be reported by voice, so that the user can accurately know the reason why the high-temperature stir-fry function could not be executed.

-When the stove timer selection switch 32 is pressed-
For example, when the user presses the stove timer selection switch 32 to set the stove timer during the normal control of the right stove burner 4 (S27: YES), the CPU 71 determines whether the battery voltage is 2.2 V or more. It is determined whether or not (S28). Here, when the battery voltage is less than 2.2 V (S28: NO), the CPU 71 turns on the battery replacement sign 53 (S29), and there is a function restriction on the timer function corresponding to the stove timer selection switch 32. It is determined whether or not it is (S30). Referring to the function restriction table 742, there is no function restriction for the timer function. Therefore, the CPU 71 determines whether or not the battery voltage is 2.1 V or more in order to confirm that there is no problem even if the stove timer is executed in the current cooking (S31).

  When the battery voltage is 2.1 V or more (S31: YES), there is no problem even if the stove timer is executed in the current cooking, so that the CPU 71 selects the right stove burner 4 selected by pressing the stove timer selection switch 32. Then, a stove timer is executed (S34). This allows the user to replace the battery after the current cooking is completed, so that the stove 1 can be improved in usability.

  On the other hand, if the battery voltage is less than 2.1 V (S31: NO), the battery voltage may be completely cut off if the stove timer is executed in the current cooking even if there is no function restriction. Therefore, the CPU 71 does not set the timer function, and notifies by voice a message indicating that the function cannot be executed due to a decrease in the battery voltage (S33). In this case, for example, a sound such as “The timer function cannot be executed due to a low battery voltage. Please replace the battery promptly” may be output from the speaker 25. Accordingly, even if the user does not notice the lighting of the battery replacement sign 53, the user feels inconvenience that the timer function cannot be used, so that the awareness of battery replacement can be enhanced.

  Then, during the normal control or the function execution, the CPU 71 determines whether the operation button 13 is pressed down again and the burning burner is extinguished (S35). If the fire has not been extinguished (S35: NO), the CPU 71 returns to S25 and continues the normal control or the function being executed. If the burning burner is extinguished (S35: YES), the board switch 18 is turned off, and the CPU 71 turns off the power supply to the safety valve 67 (S36). As a result, the safety valve 67 is also closed, and the CPU 71 ends this processing. When the timer function is executed, the corresponding burner is extinguished at the set timer time, and thus this process is forcibly terminated. Also, when the rice cooking function is executed, the burner is extinguished after boiling, so that this process is forcibly terminated.

  As described above, the stove 1 of the second embodiment is also driven by using the battery 26 as a power supply, as in the first embodiment. The CPU 71 of the stove 1 limits an executable function to a specific function in the burning burner according to the battery voltage detected by the voltage measuring unit 27. Thus, the stove 1 can make the user feel more inconvenient than in the normal case, and the consciousness of replacing the battery 26 can be enhanced. Furthermore, by leaving usable functions, minimum cooking can be performed. Therefore, the present embodiment can provide a stove 1 that is easy to use.

  In the above embodiment, the functions that can be executed by the burning burner include the temperature keeping function. The temperature keeping function is a function that can adjust the temperature of the object to be cooked to a set temperature. The temperature keeping function is a function used for cooking oil and the like, and is a function that can improve safety. Therefore, for example, even if the battery voltage drops during burner combustion, the temperature keep function is not limited. Thereby, the second embodiment can ensure the safety of the stove 1.

  Note that the present invention is not limited to the above-described embodiment, and various modifications are possible.

(Modified example common to the first and second embodiments)
The stove 1 of the first and second embodiments includes the right stove burner 4 and the left stove burner 5, but the number of stove burners on the top plate 3 may be one or three or more. The stove 1 is a table stove, but may be a built-in stove or a small gas stove of a cassette type for gas supply. Further, a stove without a grill may be used.

  In the first and second embodiments, the right stove burner 4 is a high burner and the left stove burner 5 is a standard burner. However, the right stove burner 4 may be a standard burner and the left stove burner 5 may be a high burner. Further, both the right and left stove burners 4 and 5 may be a high heat burner or a standard burner.

  Although the threshold value of the battery voltage is 2.2 V, it may be changed to another numerical value. Further, the determination processing of S6 of FIG. 6 of the first embodiment and the determination processing of S31 of FIG. 8 of the second embodiment may be omitted. At this time, for example, in the determination processing of S3 and S14 in FIG. 6 and the determination processing of S25 and S28 in FIG. 8, the determination may be made based on whether the battery voltage is 2.1 V or more.

  The notification process of S11 of FIG. 6 of the first embodiment and the notification process of S33 of FIG. 8 of the second embodiment may be omitted. Further, the voice message output from the speaker 25 in these notification processes may be a message other than the above-described embodiment, and for example, a buzzer, an alarm, or the like may be output instead of the voice.

  The stove 1 of the first embodiment limits the ignitable burner when detecting a drop in the battery voltage, and the stove 1 of the second embodiment limits the functions that can be executed when the drop in the battery voltage is detected. However, for example, the control content of the first embodiment may be combined with the control content of the second embodiment.

(Modification of First Embodiment)
In the first embodiment, when the battery voltage is reduced, the ignitable burners are limited to only the right stove burner 4 which is a high-heat-power burner. For example, even if only the left stove burner 5 which is a standard burner is limited. Good. In this case, the left stove burner 5, which has a smaller maximum heating power than the high heating power burner, must cope with the situation, so that the user can feel more inconvenience than normal operation.
