Description

Battery powered electronics

The present invention relates to a battery-powered electronic device using a furnace lamp as a power source.

For example, in a gas furnace with a plurality of burners (including those with grills), each burner is provided with electronic devices such as a solenoid valve that opens and closes a gas supply path to the burners, and the battery is supplied with a power source. It is known to make it work. In the case of operating electronic devices such as a solenoid valve corresponding to each burner using the battery as a power source, it is known that a single microcomputer is used to collectively control the operation of each electronic device in operation of each burner. However, the use of a microcomputer is expensive, so each electronic device corresponding to each burner is provided with an electronic circuit composed of an amplifier, a comparator, a timer circuit, and the like. It is known to operate independently according to the operation of each burner by the corresponding electronic circuit.

On the other hand, for example, in a gas furnace using a battery as a power source as described above, when the battery is consumed to some extent, the operation of the solenoid valve and the accompanying electronic circuit may become uncertain, so the voltage of the battery is monitored and In order to prompt the user to replace the battery when the battery voltage is lower than the predetermined value, the lamp or buzzer is notified to the user. When the battery voltage falls below the second predetermined value smaller than the predetermined value, It is known to forcibly prohibit the energization (for example, see Japanese Laid-Open Patent Publication No. Hei 6-307633).

When the voltage drop of the battery is notified to the lamp, the buzzer, or the like in this manner, as described above, in each operation of the electronic devices such as the solenoid valves independently by the corresponding electronic circuits, the batteries are burned for each burner. It is generally conceivable to have a notification means comprising a circuit for monitoring voltage or a drive circuit for a lamp or buzzer. Alternatively, it is conceivable to have a circuit configuration in which the notification is executed at the time of any burner operation by a common notification means for each burner.

However, it is costly disadvantageous to have a notification means comprising a circuit for monitoring battery voltage, a lamp or a buzzer for each burner, and in particular, for example, in a furnace with a grill, the grill is generally compared with a furnace. Since the frequency of use is low, it is not preferable to provide the notification means in correspondence with the grill with low frequency of use.

In addition, in the case of a circuit configuration in which the notification is executed at the time of operation of any burner as a common notification means for each burner, power supply power from the battery is always supplied to the circuit which constitutes the notification means at the time of any burner operation. Since it is necessary to do so, battery consumption tends to be faster and the circuit configuration tends to be complicated.

In addition, such a problem is not limited to a gas stove, but is a problem that occurs in a device such as a plurality of electronic devices that are operated independently by respective electronic circuits using a common battery as a power source.

SUMMARY OF THE INVENTION In view of the above background, the present invention provides a battery-powered electronic device which independently operates a plurality of electronic devices by respective electronic circuits using a common battery as a power source. It is an object of the present invention to provide a battery-powered electronic device that can be accurately executed while minimizing the consumption of power.

In order to achieve the above object, the battery-powered electronic device of the present invention is a plurality of electronic devices that use a common battery as a power source, and each of the electronic devices independently of each other based on a predetermined operation instruction corresponding to each electronic device. A battery-powered electronic device having a plurality of electronic circuits configured to supply electric power from a power source to operate the electronic device, wherein the voltage of the battery is applied to the electronic circuit corresponding to a specific electronic device having the highest operating frequency among the plurality of electronic devices. And a notification means for notifying when the temperature falls below a predetermined value, wherein the predetermined value is set higher than a lower limit of the battery voltage at which other electronic devices and corresponding electronic circuits can operate normally.

According to the present invention, when the voltage of the battery becomes less than the predetermined value during operation of the specific electronic device having the highest operation frequency among the plurality of electronic devices, it is notified by the notification means to prompt the user to replace the battery. do. On the other hand, when the operation of only electronic devices other than the specific electronic device, the notification means does not operate, but the lower limit of the voltage of the battery in which the other electronic device and the corresponding electronic circuit can be normally operated is lower than the predetermined value. Even if the battery voltage drops to the predetermined value at which the battery needs to be replaced, the other electronic device does not suddenly become unable to operate normally. In addition, since the operation frequency of the specific electronic device is higher than the operation frequency of the other electronic device, the operation of the specific electronic device is generally executed before the lower limit of the voltage of the battery falls, as described above. Notification is executed by the notification means. Therefore, in general, before the other electronic apparatuses and the corresponding electronic circuits become unable to operate normally, the user recognizes the necessity of battery replacement by the notification of the notification means.

In addition, if an operation of only the electronic devices other than the specific electronic device is attempted to operate the specific electronic device with a high frequency of operation even if the voltage of the battery drops below the lower limit and the other electronic device cannot operate normally. Since the notification by the notification means is executed, the user can recognize that the cause of the other electronic device not being able to operate normally by the notification is the consumption of the battery.

In addition, the battery-powered electronic device of the present invention is, for example, when the grill and the furnace, and the furnace equipped with a grill electronic device and a grill electronic device corresponding to the grill and the furnace, respectively, the notification. Means are characterized in that the electronic device for the stove electronic device is provided with the electronic device for the stove electronic device as the electronic device having the highest operating frequency.

This is because in the furnace with grills, the frequency of use of the furnace side is higher than that of the grill in general, and therefore, in the furnace electronics and the grill electronics, the frequency of the furnace electronics is higher.

Here, examples of the furnace electronic device and the grill electronic device include open / close solenoid valves installed in the furnace supply burner or the fuel supply path to the grill burner.

In the present invention, the electronic circuits corresponding to the electronic devices are provided with means for prohibiting the energization of the electronic devices corresponding to the electronic circuits when the voltage of the battery falls below a second predetermined value. The second predetermined value is set to be equal to or lower than the lower limit of the battery voltage which is lower than the predetermined value and in which each electronic circuit and electronic device can normally operate.

Even if the push button of the fire button is released, the furnace solenoid valve 4 is kept open. And raw material lighting

By pressing the fire button again, the one-valve is mechanically closed. This also applies to the grill side.

The furnace side electronic circuit 9 includes a furnace control circuit 13 for generating a signal defining the operation of the furnace solenoid valve 4 and a furnace solenoid valve 4 based on an instruction signal of the furnace control circuit 13. ), A solenoid valve driving circuit 14 for opening and closing the non-route solenoid valve 4 by energizing or blocking the energization, a voltage monitoring circuit 15 for monitoring the voltage of the battery 1, and the voltage monitoring circuit ( On the basis of the output of 15), an LED driving circuit 17 is provided which energizes the LED lamp 16 provided in the casing of the gas furnace (not shown) to flash or light the LED lamp 16. Here, the voltage monitoring circuit 15, the LED driving circuit 17 and the LED lamp 16 constitute the notifying means 18 in accordance with the configuration of the present invention.

The voltage monitoring circuit 15 monitors the voltage of the battery 1 in the ON state of the microswitch 11 (the power supply voltage is supplied to the furnace-side electronic circuit 9), and the voltage is measured by the battery 1. ) Is sent to the LED driving circuit 17 to cause the LED lamp 16 to flash when the voltage drops below the first predetermined value (2.2 V in the present embodiment) to a predetermined voltage. The voltage monitoring circuit 15 supplies the LED lamp 16 to the LED driving circuit 17 when the voltage of the battery 1 falls below the second predetermined value (2V in the present embodiment) set lower than the first predetermined value. Is sent to the furnace control circuit 13. At the same time, the second predetermined value 2V is set by the furnace side electronic circuit 9 or the converter solenoid valve 4, respectively. It is set slightly higher than the lower limit of the power supply voltage which can be normally operated.

The furnace control circuit 13 issues the open solenoid valve 4 to the solenoid valve driving circuit 14 by keeping the open furnace solenoid valve 4 open when the microswitch 11 is turned on and the power supply voltage is supplied. On the other hand, when the signal indicating that the voltage of the battery 1 is lowered below the second predetermined value (2V) from the voltage monitoring circuit 15 is sent to the solenoid valve driving circuit 14, the main furnace solenoid valve 4 Issue the closing instruction to close the furnace solenoid valve (4). In the furnace control circuit 13, an unillustrated temperature sensor or a combustion state of the furnace burner 2, which is installed in the furnace burner 2, for detecting the temperature of the heated object (cooked product), is not shown. Detection signals of sensors such as thermocouples are transmitted, and the furnace control circuit 13 has a detected temperature even when the temperature of the object to be heated exceeds a predetermined temperature or the misfire or incombustibility of the furnace burner 2 is detected. The solenoid valve 4 is closed by sending a closing signal of the furnace solenoid valve 4 to the solenoid valve driving circuit 14.

On the other hand, the grill-side electronic circuit 10 is a grill solenoid valve based on a grill control circuit 19 for generating a signal defining the operation of the grill solenoid valve 7 and an indication signal of the grill control circuit 19. A solenoid valve driving circuit 20 is configured to open or close the grill solenoid valve 7 by energizing (7) or interrupting the energization thereof.

In this case, the grill control circuit 19, like the furnace control circuit 13, gives the solenoid valve drive circuit 20 an instruction to open the grill solenoid valve 7 when the microswitch 12 is turned on and the power supply voltage is supplied. The voltage which monitors the voltage of the battery 1 in the ON state of the micro switch 12 (the state in which the power supply voltage is supplied to the grill-side electronic circuit 10) while keeping the grill solenoid valve 7 open. The monitoring unit 21 is provided, and the voltage monitoring unit 21 has a predetermined value (1.7 V in the present embodiment) or less, which is a voltage at which the voltage of the battery 1 keeps the grill solenoid valve 7 closed. When it is lowered, the closing instruction of the grill solenoid valve 7 is given to the solenoid valve driving circuit 20. In addition, in this embodiment, the lower limit of the power supply voltage which the grill control circuit 19, the solenoid valve drive circuit 20, and the grill solenoid valve 7 can operate normally is set lower than the furnace-side electronic circuit 9, The predetermined value (1.7 V) is set slightly higher than this lower limit. Although this predetermined value corresponds to a 2nd predetermined value if it respond | corresponds to the structure of this invention, it is called a 3rd predetermined value here for convenience of description here.

In addition, the grill control circuit 19 is provided with a detection signal of a thermocouple lamp sensor (not shown) for detecting the combustion state of the grill burner 5, and the grill control circuit 19 receives the grill burner in response to the detection signal. Even when misfire or misfire of (5) is detected, the solenoid valve driving circuit 20 gives a closing instruction of the grill solenoid valve 7 to close the grill solenoid valve 7.

Next, the operation of the gas furnace of the present embodiment will be described.

소화버튼을 ON조작하면 마이크로스위치(11)가 ON되고, 이에 의하여 곤로측전자회로(9)에 전지(1)로부터 전원전압이 부여되어 상기 곤로측 전자회로(9)가 기동된다. 이 때, 곤로측 전자회로(9)의 곤로제어회로(13)는 전자밸브구동회로(14)에 밸브개방지시를 내리고, 이 전자밸브구동회로(14)에 의하여 곤로전자밸브(4)에 통전시켜 상기 곤로전자밸브(4)를 개방유지시킨다. 이에 의하여, 곤로버너(2)로의 연소가스 공급이 개시되고, 또한 전지(1)를 전원으로 하는 도시하지 않은 스파커의 작동에 의하여 곤로버너(2)가 점화됨으로써 이 곤로버너(2)의 연소운전이 실행된다. 또, 이 때 전압감시회로(15)에 의하여 감시되는 전지(1)의 전압이 상기 제1 소정값(2.2V)보다도 높으면 LED구동회로(17)는 LED램프(16)에 통전시키지 않으므로, 상기 LED램프(16)는 소등유지된다.Ignition for the furnace, not shown, for the user to carry out the combustion operation of the furnace furnace burner 2

When the fire extinguishing button is turned ON, the microswitch 11 is turned on, thereby supplying a power supply voltage from the battery 1 to the furnace-side electronic circuit 9 to activate the furnace-side electronic circuit 9. At this time, the furnace control circuit 13 of the furnace side electronic circuit 9 lowers the valve opening prevention time to the solenoid valve driving circuit 14, and energizes the furnace solenoid valve 4 by this solenoid valve driving circuit 14. The open furnace solenoid valve 4 is kept open. As a result, the combustion gas supply to the gourd burner 2 is started, and the gourd burner 2 is ignited by the operation of a sparker (not shown) that uses the battery 1 as a power source to burn the gourd burner 2. The operation is executed. At this time, if the voltage of the battery 1 monitored by the voltage monitoring circuit 15 is higher than the first predetermined value (2.2V), the LED driving circuit 17 does not energize the LED lamp 16. The LED lamp 16 is kept off.

소화버튼을 ON조작하면 마이크로스위치(12)가 ON되고, 이에 의하여 그릴측 전자회로(10)에 전지(1)로부터 전원전압이 부여되어 상기그릴측 전자회로(10)가 기동된다. 이 때, 그릴측 전자회로(10)의 그릴제어회로(19)는 전자밸브구동회로(20)에 개방지시를 내리고, 이 전자밸브구동회로(20)에 의하여 그릴전자밸브(7)에 통전시켜 상기 그릴전자밸브(7)를 개방유지시킨다. 이에 의하여, 곤로버너(2)로의 연소가스 공급이 개시되고, 또한 도시하지 않은 스파커의 작동에 의하여 그릴버너(5)가 점화됨으로써 이 그릴버너(5)의 연소운전이 실행된다.Moreover, the grill ignition which is not shown in order for a user to carry out the combustion operation of the grill burner 5 is carried out.

When the fire extinguishing button is turned ON, the micro switch 12 is turned on, thereby supplying a power supply voltage from the battery 1 to the grill-side electronic circuit 10 to start the grill-side electronic circuit 10. At this time, the grill control circuit 19 of the grill-side electronic circuit 10 gives an opening instruction to the solenoid valve driving circuit 20 and energizes the grill solenoid valve 7 by the solenoid valve driving circuit 20. The grill solenoid valve 7 is kept open. As a result, the combustion gas supply to the go furnace burner 2 is started, and the grill burner 5 is ignited by the operation of a sparker (not shown), whereby the combustion operation of the grill burner 5 is executed.

Next, the battery 1 is consumed by the power supply to the furnace furnace solenoid valve 4, the grill solenoid valve 7, and the like as described above, and the voltage of the battery 1 is set to the first predetermined value (2.2V). In the case where the furnace burner 2 is operated in a state where the power supply voltage is supplied to the furnace-side electronic circuit 9, the LED driving circuit is operated by the voltage monitoring circuit 15 of the furnace-side electronic circuit 9. Signal the furnace 17 to flash the LED lamp 16. As a result, the LED driving circuit 17 continues to energize the LED lamp 16 and makes the LED lamp 16 blink. Then, the user needs to be notified of the replacement of the battery 1 by the blinking of the LED lamp 16.

In addition, when the LED lamp 16 is blinking, the voltage of the battery 1 is higher than the second predetermined value or the third predetermined value, so that the operation of the go-rou burner 2 or the grill burner 5 can be performed without interruption. Can be. In addition, when the user stops the combustion operation of the gourd burner 2 once by notification of the blinking of the LED lamp 16, replaces the battery with a new one, and restarts the burn operation of the gourd burner 2, the voltage monitoring is performed. Since the voltage of the battery 1 monitored by the circuit 15 becomes higher than the first predetermined value (2.2V), the LED lamp 16 is kept off.

On the other hand, when the operation of only the grill burner 5 is performed in the state where the voltage of the battery 1 has fallen to the first predetermined value (2.2V) as described above (the power supply to the grill side electronic circuit 10 is performed. In the case where the voltage is supplied and the power supply voltage is not supplied to the furnace side electronic circuit 9, the furnace side electronic circuit 9 is not energized to the LED lamp 16 in a non-operational state. Notice by flashing) is not made. Nevertheless, at this time, the voltage of the battery 1 is higher than the third predetermined value (1.7 V) which prohibits the operation of the grill burner 5, which keeps the grill solenoid valve 7 closed. Since it is higher than the lower limit of the power supply voltage which can be normally operated between the electronic circuit 10 and the grill solenoid valve 7, the grill burner normally until the voltage of the battery 1 is further lowered below the third predetermined value (1.7V). (5) can be driven. In general, the gas furnace with the grill has a higher frequency of use of the furnace burner 2 than the frequency of use of the grill burner 5, so that the voltage of the battery 1 falls below the first predetermined value (2.2V). It is rare that the operation of the gourd burner 2 is not carried out over a long period of time, and when the operation of the gourd burner 2 is executed, the LED lamp 16 blinks as described above, and the battery 1 is supplied to the user. Notify you of the need for replacement.

Therefore, even if the grill burner 5 is not driven by the blinking of the LED lamp 16, the user can basically recognize the need to replace the battery 1 before the grill burner 5 becomes unusable.

소화버튼을 ON조작하면), 이 때 기동하는 곤로측 전자회로(9)의 전압감시회로(15)의 지시에 의하여 LED구동회로(17)가 LED램프(16)에 계속적으로 통전시켜 이 LED램프(16)를 점등시킨다. 동시에 전압감시회로(15)의 지시에 의하여 곤로제어회로(13)가 전자밸브구동회로(14)애 곤로전자밸브(4)의 개방지시를 내리지 않으므로, 전자밸브구동회로(14)는 곤로전자밸브(4)로의 통전을 금지하여 이 곤로전자밸브(4)를 폐쇄유지시킨다. 이에 의하여 전지(1)의 전압이 곤로제어회로(13) 등의 정상적인 작동에 필요한 전원전압의 하한값에 가까운 상기 제2 소정값(2V)까지 저하되면, 곤로버너(2)로의 가스공급이 강제적으로 차단되어 곤로버너(2)의 연소운전이 금지되고, 곤로전자밸브(4)의 비정상적인 개폐동작이 발생하는 것과 같은 사태가 배제된다. 그리고 이 때 LED램프(16)의 점멸에 의하여 사용자는 전지(1)의 교환필요성을 인식할 수 있게 된다.Next, despite the notification by the flashing of the LED lamp 16 as described above while the go-ro burner 2 is in use, the battery 1 is further consumed without replacing the battery 1. When the go-ro burner 2 is to be operated when the voltage of the battery 1 drops to the second predetermined value (2 V) (ignition ignition)

When the fire extinguishing button is turned ON, the LED driving circuit 17 continuously energizes the LED lamp 16 according to the instruction of the voltage monitoring circuit 15 of the electronic circuit 9 on the starting side at this time. Turn on (16). At the same time, since the furnace control circuit 13 does not issue the open direction of the furnace valve solenoid valve 4 in the solenoid valve drive circuit 14 by the instruction of the voltage monitoring circuit 15, the solenoid valve drive circuit 14 is the furnace furnace valve. The flow of the furnace solenoid valve 4 is kept closed by energizing the furnace (4). As a result, when the voltage of the battery 1 drops to the second predetermined value (2V) close to the lower limit of the power supply voltage required for the normal operation of the furnace control circuit 13 or the like, the gas supply to the furnace furnace burner 2 is forcibly forced. The combustion operation of the go-ro burner 2 is blocked, and the situation such as abnormal opening / closing operation of the go-ro solenoid valve 4 occurs is excluded. At this time, by blinking the LED lamp 16, the user can recognize the need for replacement of the battery (1).

On the other hand, during operation of the grill burner 5 alone, since the voltage of the battery 1 is lowered to the second predetermined value 2V, the voltage is higher than the third predetermined value 1.7V. The circuit 10 operates as usual, so that the operation of the grill burner 5 is performed without any trouble. At this time, the LED lamp 16 is not turned on. When the voltage of the battery 1 is further lowered and lowered to the third predetermined value (1.7 V), the operation of the voltage monitoring unit 21 causes the grill control circuit 19 to move to the solenoid valve driving circuit 20. Since the opening instruction of the grill solenoid valve 7 is not issued, the solenoid valve driving circuit 20 prohibits energization of the grill solenoid valve 7 so that the grill solenoid valve 7 is kept closed. As a result, when the voltage of the battery 1 drops to the third predetermined value (1.7 V) which is close to the lower limit value of the power supply voltage required for the normal operation of the grill control circuit 21 or the like, the gas supply to the grill burner 5 is forced. This prevents the combustion operation of the grill burner 5 and prevents the opening and closing of the grill solenoid valve 7.

통지는 이루어지지 않지만, 이 때 전지(1)의 전압(1.7V 이상)은 상기 제2 소정값보다도 낮으므로, 상기 그릴버너(5)보다도 사용빈도가 높은 곤로버너(2)의 운전시에 LED램프(16)가 확실하게 점등되어 그릴버너(5)의 연소운전이 금지되기 전에 사용자에게 전지(1)가 소모되어 이 전지(1)를 교환해야 한다는 것을 인식시킬 수 있다. 또, 만약 그릴버너(5)의 운전이 금지되기 전에 장기간에 걸쳐서 곤로버너(2)가 사용되지 않거나, 사용자가 곤로버너(2)의 운전시 LED램프(16)의 점등 혹은 점멸을 못보았다고 하더라도, 그릴버너(5)의 운전이 금지된 후 사용자가 곤로버너(2)의 운전을 하려고 하면 LED램프(16)가 점등하므로 사용자는 전지(1)의 소모에 의하여 그릴버너(5)의 운전을 실행할 수 없게 된 것을 인식할 수 있어 기구의 고장으로 오인하는 것과 같은 사태를 막을 수 있다.In this case, when the combustion operation of the grill burner 5 is prohibited as described above during the operation of the grill burner 5 alone, the LED lamp 16 is turned on.

No notification is made, but at this time, the voltage of the battery 1 (1.7 V or more) is lower than the second predetermined value, so that the LED at the time of operation of the go-burner 2 having a higher frequency of use than the grill burner 5 is operated. Before the lamp 16 is reliably lit and the burn operation of the grill burner 5 is prohibited, the user can recognize that the battery 1 is exhausted and the battery 1 needs to be replaced. In addition, even if the go-ro burner 2 is not used for a long time before the operation of the grill burner 5 is prohibited, or if the user does not see the LED lamp 16 lit or blinking when the go-burner 2 is operated. When the user attempts to operate the go-ro burner 2 after the operation of the grill burner 5 is prohibited, the LED lamp 16 lights up so that the user does not operate the grill burner 5 due to the exhaustion of the battery 1. It can recognize that it can't be executed, and can prevent a situation such as mistaken for failure of the apparatus.

Thus, according to the gas furnace of this embodiment, even if the notification means 18 formed only on the side of the furnace with high use frequency does not notify the need of replacement of the battery 1 at the time of using only the grill burner 2 with low use frequency. With this simple configuration, the user can accurately recognize the need for replacement of the battery 1.

In addition, when the grill burner 2 is used only, the power supply to the notification means 18 does not need to be executed, and thus the consumption of the battery 1 can be minimized.

In the present embodiment, the LED lamp 16 blinks when the voltage of the battery 1 drops below the first predetermined value (2.2 V) by the LED lamp 16. And the operation of the go-ro burner 2 when the voltage of the battery 1 is further lowered below the second predetermined value (2V) or the like by the point of the LED lamp 16 or the like. In the state where the voltage of 1) becomes below the first predetermined value (2.2V), the need for replacement of the battery 1 may be notified only by blinking or lighting the LED lamp 16 at all times.

Moreover, in this embodiment, the voltage 2V of the battery 1 which prohibits the operation of the gourd burner 2 (closes and maintains the furnace solenoid valve 4), and prohibits the operation of the grill burner 5 { A battery for which the grill solenoid valve 7 is kept closed is set to a voltage (1.7 V) different from that of the battery 1, but the battery 1 should be notified of the need for replacement of the battery 1, regardless of the detection error of the battery 1 voltage. If it is lower than the voltage (2.2V) of (1), the voltage of the battery 1 which prohibits the operation of the go-burner 2 and the voltage of the battery 1 which prohibits operation of the grill burner 5 may be made the same. Do. Even in this case, if the go-burner 2 is to be operated after the operation of the grill burner 5 is prohibited, the go-burner 2 is also prohibited and the LED lamp 16 is turned on, so that the user can operate the battery 1. It can be recognized that the grill burner 5 cannot be operated due to the consumption of.

Next, a second embodiment of the present invention will be described with reference to FIG. 2 is a system configuration diagram of the battery powered electronic device of the present embodiment. In addition, in this embodiment, about the component same as embodiment of FIG. 1, the same code | symbol is attached | subjected to embodiment of FIG. 1, and detailed description is abbreviate | omitted.

소화버튼의 ON조작에 이하여 ON되는 마이크로스위치(11)를 통하여 전지(1)를 전원으로 하여 상기한 바와 같이 작동하도록 되어 있다.In FIG. 2, the battery-powered electronic device of the present embodiment is a gas furnace with a kitchen timer, and includes a furnace burner 2, a furnace solenoid valve 4 (electronic device), and a furnace side electron having the same configuration as the embodiment of FIG. The circuit 9 and the LED lamp 16 are provided, and the furnace solenoid valve 4 (electronic device), the furnace side electronic circuit 9, and the LED lamp 16 are not shown.

The battery 1 is operated as described above by the power source of the battery 1 via the micro switch 11 which is turned on following the ON operation of the fire extinguishing button.

On the other hand, in the gas furnace of 2nd Embodiment, the kitchen timer 22 (timer buzzer) which a user can know a cooking time etc. is provided in the casing which is not shown as an electronic device which uses the battery 1 as a power source, A timer control circuit 23 (electronic circuit) for controlling the operation of the kitchen timer 22 independently of the electronic circuit 9 is provided in the circuit unit 8 including the electronic circuit 9.

In this case, the timer control circuit 23 is set so that the timer time is set by a manipulator (not shown). The timer control circuit 23 operates the timer switch 24 in the set state of the timer time to turn on the battery through the timer switch 24. Power supply voltage is supplied from 1) to operate. The timer control circuit 23 energizes the kitchen timer 22 when the timer time set in the state where the power supply voltage is supplied elapses and rings it.

In addition, in this embodiment, the lower limit of the power supply voltage which the timer control circuit 23 and the kitchen timer 22 can operate is 1.7V, for example, and the said 1st predetermined value (2.2V) or the 2nd predetermined value (2V). Although lower than the first predetermined value (2.2V), the lower limit of the power supply voltage at which the timer control circuit 23 and the kitchen timer 22 can operate and the voltage which prohibits the operation of the gorou burner 2 (second predetermined) The value) may be the same.

Next, the operation of the gas furnace of the present embodiment will be described.

소화버튼을 ON조작하여 곤로버너(2)를 운전하려고 할 때 상기 제1도와 같이 곤로측 전자회로(9)나 곤로전자밸브(4), LED램프(16)가 작동하고, 전지(1)의 전압이 상기 제1 소정값(2.2V)까지 저하된 상태에서는 LED램프(16)가 점멸하고, 전지(1)의 전압이 상기 제2 소정값(2V)까지 더 저하된 상태에서는 LED램프(16)가 점등함과 아울러 곤로전자밸브(4)가 강제적으로 폐쇄유지되어 곤로버너(2)의 운전이 금지된다. 그리고, LED램프(16)의 점멸 혹은 점등에 의하여 전지(1)의 교환필요성을 사용자에게 통지한다.Ignition for stoves not shown by the user

When the fire extinguishing button is turned on to operate the furnace burner (2), the furnace side electronic circuit (9), the furnace furnace valve (4), and the LED lamp (16) operate as shown in FIG. The LED lamp 16 blinks when the voltage is lowered to the first predetermined value (2.2V), and the LED lamp 16 when the voltage of the battery 1 is further lowered to the second predetermined value (2V). Lights up and the furnace furnace solenoid valve 4 is forcibly closed and the operation of the furnace furnace burner 2 is prohibited. Then, the user needs to be notified of the need for replacement of the battery 1 by the blinking or lighting of the LED lamp 16.

On the other hand, when the user sets the timer time with the manipulator (not shown) to use the kitchen timer 22 and turns on the timer switch 24, the power supply voltage is applied to the timer control circuit 23 from the battery 1. The timer control circuit 23 starts the time measurement, and when the measured time passes the set timer time, the timer control circuit 23 energizes the kitchen timer 22 to raise it. In this case, the kitchen timer 22 may be used independently of the operation of the gourd burner 2 when checking the cooking time by the gourd burner 2.

When the kitchen timer 22 is used alone, the power supply voltage is not supplied to the furnace-side electronic circuit 9, so that the voltage of the battery 1 reaches the first predetermined value (2.2V) at which the battery must be replaced. Even if it is deteriorated (in this state, the timer control circuit 23 and the kitchen timer 22 operate without any problem), the need for replacing the battery 1 by the LED lamp 16 is not notified. Nevertheless, the frequency of use of the kitchen timer 22 is generally lower than that of the gorun burner 2, and the lower limit value at which the kitchen timer 22 or the timer control circuit 23 can operate normally blinks the LED lamp 16. Or lower than the first predetermined value 2.2V or the second predetermined value 2V to be turned on. Therefore, before the voltage of the battery 1 decreases below the lower limit at which the kitchen timer 22 or the timer control circuit 23 can operate, the battery 1 may be turned off before the kitchen timer 22 is normally operated. Users can be aware of the need for exchange.

In addition, if the voltage of the battery 1 falls below the lower limit at which the kitchen timer 22 or the timer control circuit 23 can be operated, and the kitchen timer 22 does not operate normally, 2) is not used, or even if the user does not see the LED lamp 16 turned on or flashing when the go-ro burner 2 is operated, the LED lamp 16 turns on when the user tries to operate the go-ro burner 2, The user can recognize that the kitchen timer 22 does not operate normally due to the exhaustion of the battery 1, thereby preventing a situation such as mistaken for a malfunction of the mechanism.

Thus, according to the gas furnace of this embodiment, even if the necessity of replacement of the battery 1 is not notified by the notification means 18 formed only in the furnace side with a high frequency of use, when only the kitchen timer 22 with low use frequency is used. With this simple configuration, the user can accurately recognize the need for replacement of the battery 1.

Next, a third embodiment of the present invention will be described with reference to FIG. 3 is a system configuration diagram of the battery powered electronic device of the present embodiment. In addition, in this embodiment, about the component same as embodiment of FIG. 1, the same code | symbol is attached | subjected to embodiment of FIG. 1, and detailed description is abbreviate | omitted.

소화버튼의 ON조작에 의하여 ON되는 마이크로스위치(11)를 통하여 전지(1)를 전원으로하여 상기한 바와 같이 작동하도록 되어 있다.In FIG. 3, the battery-powered electronic device of the present embodiment is a gas furnace with a grill, and includes a furnace burner 2, a furnace solenoid valve 4 (electronic device), and a furnace side electronic circuit having the same configuration as the embodiment of FIG. (9), an electric furnace ignition (not shown) provided with an LED lamp (16), a furnace solenoid valve (4; electronic device), a furnace side electronic circuit (9), and an LED lamp (16).

The battery 1 is powered by the micro switch 11 which is turned on by the ON operation of the fire extinguishing button, and is operated as described above.

On the other hand, the gas furnace of 3rd Embodiment is an electronic apparatus which uses the grill operation LED lamp 25 as a power source for the battery 1 to notify that the said grill burner is carrying out the combustion operation at the time of the combustion operation of the grill burner 5. The grill operation LED is provided in a casing (not shown) and detects the combustion operation of the grill burner 5, and the grill operation LED is detected by the combustion operation detection of the grill burner by the grill monitoring circuit 26. The electronic circuit 28 which consists of LED drive circuit 27 which turns on the lamp 25 is provided in the circuit unit 8 containing the said furnace side electronic circuit 9. As shown in FIG.

소화버튼의 ON조작에 따라서 ON되는 마이크로스위치(12)를 통하여 전자회로(9)와는 독립적으로 전지(1)로부터 전원전압이 급전되도록 되어 있다. 그리고, 전원전압의 급전시에 있어서 그릴감시회로(26)에는 그릴버너(5)의 케이싱에 구비한 열전대(29)의 검지신호가 보내지도록 되어 있고, 이 그릴감시회로(26)는 그 검지신호에 의하여 그릴버너(5)의 연소운전을 검지하고, 그에 따라서 LED구동회로(27)에 그릴운전 LED램프(25)의 점등지시를 내리도록 되어 있다.In this case, the grill monitoring circuit 26 and the LED driving circuit 27 are grill ignition not shown.

The power supply voltage is supplied from the battery 1 independently of the electronic circuit 9 via the microswitch 12 that is turned on in response to the fire button being turned on. When the power supply voltage is supplied, the detection signal of the thermocouple 29 provided in the casing of the grill burner 5 is transmitted to the grill monitoring circuit 26. The grill monitoring circuit 26 transmits the detection signal. The combustion operation of the grill burner 5 is detected by this, and the lighting instruction of the grill operation LED lamp 25 is given to the LED drive circuit 27 accordingly.

In addition, in this embodiment, the lower limit of the power supply voltage which can operate the grill monitoring circuit 26, LED drive circuit 27, and grill operation LED lamp 25 is 1.7V, for example, said 1st predetermined value (2.2V). Or lower than the second predetermined value (2V), but lower than the first predetermined value (2.2V), the power supply voltage of the grill monitoring circuit 26, the LED driving circuit 27, and the grill driving LED lamp 25 The lower limit value and the voltage (second predetermined value) forbidding the operation of the goro burner 2 may be the same.

Next, the operation of the gas furnace of the present embodiment will be described.

소화버튼을 ON조작하여 곤로버너(2)를 운전하려고 할 때 상기 제1도와 같이 곤로측 전자회로(9)나 곤로전자밸브(4), LED램프(16)가 작동하고, 전지(1)의 전압이 상기 제1 소정값(2.2V)까지 더 저하된 상태에서는 LED램프(16)가 점멸하고, 전지(1)의 전압이 상기 제2 소정값(2V)까지 저하된 상태에서는 LED램프(16)가 점등함과 아울러 곤로전자밸브(4)가 강제적으로 폐쇄 유지되어 곤로버너(2)의 운전이 금지된다. 그리고, LED램프(16)의 점멸 혹은 점등에 의하여 전지(1)의 교환필요성을 사용자에게 통지한다.Ignition for stoves not shown by the user

When the fire extinguishing button is turned on to operate the furnace burner (2), the furnace side electronic circuit (9), the furnace furnace valve (4), and the LED lamp (16) operate as shown in FIG. The LED lamp 16 flashes when the voltage is further lowered to the first predetermined value (2.2V), and the LED lamp 16 is turned on when the voltage of the battery 1 is lowered to the second predetermined value (2V). Lights up and the furnace solenoid valve 4 is forcibly closed and the operation of the furnace furnace burner 2 is prohibited. Then, the user needs to be notified of the need for replacement of the battery 1 by the blinking or lighting of the LED lamp 16.

소화버튼을 ON조작하면 마이크로스위치(12)가 ON되어, 전자회로(28)에 전지(1)로부터 전원전압이 부여되어 이 전자회로(28)가 기동된다. 그리고, 이 때 열전대(29)의 신호에 의하여 그릴버너(5)의 착화가 검지되면, 그릴감시회로(26)가 LED구동회로(27)에 그릴운전 LED램프(25)의 점등지시를 내리고, 이에 의하여 LED구동회로(27)가 그릴운전 LED램프(25)에 통전하여 이 LED램프(25)를 점등시킨다.On the other hand, the grill ignition (not shown) for the user to perform the operation of the grill burner (5)

When the fire extinguishing button is turned ON, the microswitch 12 is turned on, the power supply voltage is applied to the electronic circuit 28 from the battery 1, and the electronic circuit 28 is activated. At this time, if the ignition of the grill burner 5 is detected by the signal of the thermocouple 29, the grill monitoring circuit 26 gives the LED driving circuit 27 a lighting instruction of the grill operation LED lamp 25, As a result, the LED driving circuit 27 energizes the grill driving LED lamp 25 to turn on the LED lamp 25.

In this case, since the power supply voltage is not supplied to the furnace-side electronic circuit 9 during the operation of the grill burner 5 alone, even if the voltage of the battery 1 drops to the first predetermined value (2.2V) at which the blocking must be replaced. (In this state, the electronic circuit 28 and the grill operation LED lamp 25 operate normally.) The necessity of replacing the battery 1 by the LED lamp 16 is not notified. Nevertheless, the frequency of use of the grill burner 5 is generally lower than that of the go-ro burner 2, and the lower limit on which the electronic circuit 28 or the grill operation LED lamp 25 can be normally operated is determined by the LED lamp 16. It is lower than the said 1st predetermined value (2.2V) or the 2nd predetermined value (2V) which flashes and lights. Therefore, the LED lamp 25 flashes or lights up by the operation of the go-ro burner 2 before the voltage of the battery 1 drops below the lower limit at which the electronic circuit 28 or the grill operation LED lamp 25 can operate. Thus, the user can recognize the need for replacement of the battery 1 before the LED lamp 25 is not normally turned on.

In addition, if the voltage of the battery 1 falls below the lower limit at which the electronic circuit 28 or the grill operation LED lamp 25 is operable, the golow burner (for a long time) until the LED lamp 25 is not normally lit. 2) is not used, or even if the user has not seen the LED lamp 16 turned on or flashing when the go-ro burner 2 is operating, the LED lamp 16 turns on when the user tries to drive the go-ro burner 2. The user can recognize that the grill driving LED lamp 25 does not operate normally due to exhaustion of the battery 1, thereby preventing a situation such as mistaken for a malfunction of the mechanism.

Thus, according to the gas furnace of this embodiment, even if the notification means 18 formed only in the furnace side with high use frequency does not notify the need of replacement of the battery 1 at the time of using only the grill burner 5 with low use frequency. With this simple configuration, the user can accurately recognize the need for replacement of the battery 1.

In addition, in each embodiment described above, although the LED lamp was used as the notification means 18, you may use a buzzer instead.

According to the battery-powered electronic device of the present invention, the notification for prompting the replacement of the battery can be accurately executed without interruption with a simple configuration by a single notification means provided in the electronic circuit corresponding to the specific electronic device having the highest operation frequency. . Since the notification means only needs to be operated during the operation of the specific electronic device, it is not necessary to supply power from the battery to the circuit constituting the notification means during the operation of other electronic devices, thereby significantly reducing battery consumption. have. According to the invention of claim 1, with a simple configuration by a single notification means provided in an electronic circuit corresponding to a specific electronic device having the highest operation frequency, notifications for prompting the replacement of batteries can be executed accurately. Since the notification means only needs to be operated during the operation of the specific electronic device, it is not necessary to feed power to the circuit constituting the notification means from the battery when the other electronic device is operated, so that battery consumption can be minimized.

Therefore, according to the present invention, when a plurality of electronic devices are operated independently by an electronic circuit using a common battery as a power source, the battery voltage drop notification can be carried out accurately with a simple configuration and with minimum battery consumption. have.

In the invention of claim 2, since it is not necessary to form the notification means in correspondence with both the furnace and the grill by applying it to the furnace with the grill, a furnace with a grill having a low price can be provided.

According to the invention of claim 3, the notification means for prompting the replacement of the battery when the battery voltage falls below the predetermined value is executed by the notification means. Since the energization to the electronic device is prohibited before the normal operation of the electronic device cannot be performed when the voltage of the electronic device further lowers to the second predetermined value, it is possible to exclude the occurrence of abnormal operation of the electronic device.
