Duanzhuang A7 B7 V. Description of the Invention (2) The gas furnace using batteries as the power source is as described above. The ignition components such as igniters also operate with batteries as the power source. When the igniter, which consumes a lot of power, operates, the voltage of the battery may drop sharply and instantly. Therefore, if the igniter is operated under the condition that the remaining battery life is shortened and the output power of the battery is reduced, the voltage of the battery may drop below the voltage of the above-mentioned replacement battery momentarily. At this time, the battery voltage sometimes recovers above the replacement battery voltage after the igniter stops operating, but the residual life of the battery is obviously very small. * Therefore, there is a gas furnace where the battery voltage drops to the above replacement only once. Below the voltage, whether or not the battery voltage is restored, the CPU will continue to be notified to urge battery replacement (until the battery is replaced) < * This will prevent the battery voltage from falling below the minimum guaranteed voltage during cooking, causing gas The furnace becomes unable to use β. However, when the igniter is operated under the condition that the remaining life of the battery is shortened, the voltage of the battery may drop below the above-mentioned prohibited operating voltage-voltage which is lower than the voltage of the replacement battery. At this time, because the forbidden operation circuit will be activated and the CPU will be prohibited, the above-mentioned notification by the CPU to urge the battery replacement will not be activated. ”After the igniter stops operating, the battery voltage returns to the forbidden operation voltage (for example, 1.9V). ) Above, when the prohibition of the prohibition operation circuit is lifted, and the control circuit starts to operate, if the battery voltage is below the replacement battery voltage (for example, 2 · 〇ν), the control circuit can detect and notify, but if the battery When the voltage is restored to exceed the above-mentioned replacement battery voltage, even if the battery's residual life is actually short, it is still not possible to tell that the paper size should be replaced.

The object of the present invention is to provide a burning device that can eliminate the above-mentioned defects, and when the remaining life of the battery is short, it can surely perform a notification to prompt the replacement of the battery. In order to achieve the above object, the present invention is provided with: an ignition member that uses a battery as a power source to ignite in the combustion section; a battery voltage detection circuit capable of detecting the voltage of the battery; and using the battery as a power source to control the operation of the combustion section, and A control circuit that causes the notification component to operate when the voltage of the battery detected by the battery voltage detection circuit falls below a reference voltage by more than one; and when the voltage of the battery detected by the battery voltage detection circuit is higher than the above The first reference voltage is low, and it becomes a second reference voltage set above the minimum guaranteed operating voltage that can ensure the normal operation of the control circuit. The combustion device of the prohibited operation circuit that prohibits the control circuit from operating is characterized by: It is provided that, when the voltage of the battery detected by the battery voltage detection circuit is equal to or lower than the second reference voltage, the voltage drop signal outputting the voltage drop signal to the control circuit_ is continued to be outputted to the circuit t. The forbidden operation of the operating circuit is canceled. When the operation starts, check whether it is available. Said voltage drop signal voltage output circuit outputs the down signal when the output signal voltage drop, so that the operation of said notification means. According to the present invention, if the ignition member is operated, a large amount of power is taken out from the battery, and when the battery voltage becomes lower than the second reference voltage, the prohibition operation circuit prohibits the operation of the control circuit.

Description of the invention (4) The voltage of the above battery detected by the voltage detection circuit is below the above first reference voltage, The following notification components will not operate. However, at this time, the voltage drop signal output circuit continues to output the voltage drop signal to the control circuit. Therefore, the operation of the ignition member is stopped, the voltage of the battery is restored to exceed the second reference voltage, the prohibition operation of the prohibition operation member is canceled, and the control circuit can be confirmed by the control circuit when the operation is resumed. The voltage drop signal output circuit outputs the voltage drop signal, thereby recognizing that the voltage of the battery has become lower than the second reference voltage *. Even if it occurs momentarily, the voltage of the battery becomes lower than the second reference voltage. In the state, it can be judged that the remaining life of the battery is very small, and the output power of the battery is decreasing. Therefore, when the control circuit starts to operate when the voltage drop signal is output again, the control circuit is caused to operate. This informs the actor that the residual life of the battery is very small. "-The above-mentioned prohibited operation circuit is characterized in that the voltage of the battery detected by the battery voltage detection circuit becomes below the second reference voltage and decreases from the voltage. When the signal signal output circuit outputs the voltage drop signal, the operation of the control circuit is prohibited. The voltage drop signal output circuit or the forbidden operation circuit is constituted by an electronic circuit, but the performance of the electronic parts constituting the electronic circuit is not uniform, so it is likely to occur. The battery detected by the battery electric detection circuit When the voltage becomes equal to or lower than the second reference voltage, the above prohibition is required (please read the note on the back and fill in the note)-the size of the paper and thread paper is in accordance with the Chinese national standard (CNS > Α4 size (210X297)) -7 -Printed by A7 B7_ by the Central Laboratories of the Ministry of Economic Affairs, Shellfish Consumer Cooperatives. 5. Description of the Invention (5) The prohibition of the above-mentioned control circuit of the stop-action circuit is earlier than the output of the above-mentioned voltage drop signal of the above-mentioned voltage drop signal wheel-out circuit. In this case, because the operation of the control circuit is stopped, the voltage of the battery rises, and the voltage drop signal output circuit may not output the voltage drop signal. Therefore, the prohibited operation circuit of the present invention is only When the voltage drop signal output circuit outputs the voltage drop signal, the operation of the control circuit is prohibited. Therefore, when the operation prohibition of the control circuit by the prohibition operation circuit is released, the voltage drop signal will be output. Therefore, the notification for promptly replacing the battery can be surely made. An example of the embodiment of the invention is as follows.

Description of the invention (7) flickers or lights up, The user is prompted to replace the battery 13. Next, referring to FIG. 2, the process of notifying the replacement time of the battery 13 of the gas furnace of the present embodiment will be described. FIG. 2 shows the main part of the electronic unit 5 shown in the first circle. Circuit structure diagram. The CPU 30 is equipped with output and input ports, which together with the unillustrated ROM, RAM and other ashamed components constitute the control circuit 14. The CPU 30 is connected to the output of the output port and P2 through the electric crystal 31, 32. Open and maintain the safety valve 3 and close the valve. * Because of the output of output port P3, spark discharge is generated by the ignition electrode 25 by the igniter 26. The output of output ports P3 and P4 is driven by the solenoid valve. IC33, open and close solenoid valve 10. Because the minimum guaranteed operating voltage of CPU30 in this embodiment is 1.8V, when the voltage of battery 13 drops below 1.8V, the CPU may malfunction. Therefore, it is divided into 1.9V (Equivalent to the second aspect of the present invention Quasi-voltage), 2.0V (equivalent to the first reference voltage of the present invention), and 2.2V (equivalent to the first reference voltage of the present invention), the CPU30 monitors the voltage of the battery 13- Each voltage level is used to notify the replacement of the battery 13. The voltage of the battery 13 at the beginning of use is about 3V. The comparator 35 is used to detect that the voltage of the battery 13 has dropped to 2.2V. 37 Use the voltage divided by the 1.5V stable voltage generated by the regulator 34 as the reference voltage, input it to the positive input terminal, and divide the output voltage of the battery 13 by the resistors 38 and 39 (according to the battery 13). The voltage changes) as a comparison voltage input to the negative input terminal. Furthermore, the comparator 35 and resistors 36 to 39 constitute the battery voltage detection circuit of the present invention. The resistance of the resistors 36 to 39 is set to the voltage of the battery 13 Becomes (please read the note on the back side and then fill in this page)-binding and ordering the Γ line ----- Γ This paper size is in accordance with the Chinese national standard (CNS) A4 Zhuge (210X297 mm) -10- Consumption Cooperation between Employees of the Central Government Bureau of the Ministry of Economic Affairs Du printed A7 B7_ Explanation (8) When the voltage is below 2.2V, the output of the comparator 35 is switched from 0V to a high-impedance state, and the output terminal of the comparator 35 is increased through the resistor 40. Therefore, when the voltage of the battery 13 becomes 2.2V or less, the CPU The input level of input port 卩 7 is switched from 0V (logic low level) to logic high level. When the CPU 30 recognizes, the input level to input port P72 becomes a logic high level, and when the voltage of battery 13 becomes below 2.2V, it will output from Port P5 outputs 0V intermittently, causing the battery replacement indicator 24 to flash (the first notification). The flashing of the battery replacement indicator 24 allows the user to recognize that it is time to replace the battery 13. Furthermore, a resistor 63 for limiting the current is connected in series to the battery replacement indicator 24, and the comparator 41 is used to detect that the voltage of the battery 13 has fallen to 2.0V, and the resistors 44 and 45 are used to reduce the 1.5V generated by the regulator 34. The voltage divided by the stable voltage is used as the reference voltage input to the positive input terminal, and the voltage divided by the output voltage of the battery 13 by the resistors 44 and 45 (varies according to the voltage of the battery 13) is used as the comparison voltage input to the negative input terminal. . Furthermore, the comparator 41 and the resistors 42 to 45 constitute a battery voltage detection circuit of the present porcelain. The resistance value of the resistors 42 to 45 is set so that when the voltage of the battery 13 becomes less than 2.0V, the output of the comparator 41 is switched from 0V to a high-impedance state, and the output terminal of the comparator 41 is increased through the resistor 46. Therefore, When the voltage of the battery 13 becomes below 2.0V, it turns into the input port of the CPU? The input level of 8 is switched from 0V (logic low level) to logic high level. When CPU30 recognizes the input to input, the P82 input level becomes a logic high level, and when the voltage of battery 13 becomes less than 2.0V, it outputs 0V continuously from the output port, so that the battery replacement indicator 24 lights up (second notification).

Description of the invention (9) The lighting of the battery indicator 24 makes the user recognize that it is necessary to replace the battery immediately 13 θ In a state where the remaining life of the battery 13 is not much When the structure that consumes a lot of power such as the igniter 26 or the solenoid valve 10 is operated, the voltage of the battery 13 may drop below 2.2V or even below 2.0V. At this time, the igniter 26 or the solenoid valve 10 After the operation stops, the voltage of the battery 13 sometimes recovers to 2.2V, or more than 2.0V. However, when the voltage of the battery 13 drops so much, it seems that the remaining life of the battery is not much, and the battery 13 turns out. The capacity has been reduced. Therefore, in the CPU 30 by the comparator 35 When the output recognizes that the voltage of the battery 13 becomes less than 2.2V, or the output of the comparator 41 recognizes that the voltage of the battery 41 becomes less than 2.0V, the output of the comparator 35 or the comparator 41 will be continued regardless of the subsequent output. The first notification or the second notification described above. Second, the comparator 47 is composed of a voltage detection IC 48 (equivalent to the battery voltage detection circuit of the present invention), buffer amplifiers 50 and 61, and resistors 51 to 55. Signal output circuit 16. Here, the reference voltage VB of the positive input terminal of the input comparator 47 is switched according to the output of the comparator 47. That is, when the output of the comparator 47 is 0V, Vbi = (R54 · κ · 55) / {Κ · 54 · feet 55+ feet 53 (Chinese 54 + feet 55)) = R54 / (R54 + R53 + R54 / R55) · 1_5 (V) When the output of comparator 47 is in a high impedance state, VB2 = R54 / (R53 + R54) · 1.5 (V) (> VB1) (R53 ~ R55 are the resistance values of resistors 53 ~ 55 respectively): — ^ ----—, sign% 1 /.

Description of the invention (1G) On the other hand, the negative input terminal of comparator 47 is input, and the resistors 51 and 52 divide the output voltage of IC48 through buffer amplifier 50 for voltage detection. When the voltage of battery 13 drops below 1.9V, the voltage detection IC48 switches the output from high impedance to 0V. The output terminal of the voltage detection IC48 is increased from the resistor 49 to 1.5V. Therefore, when the voltage of the battery 13 drops below 1.9V, the input voltage of the buffer amplifier 50 is switched from 0V to 1.5V. Following this, the buffer amplifier 50 The output voltage is also switched from 0V to 1.5V. The resistance of resistors 51 to 55 is set so that when the voltage of battery 13 drops below 1.9V, that is, when the output of the buffer amplifier 50 is switched from 1.5V to 0V, the output of comparator 47 is switched from 0V to high impedance. State> Here, as described above, when the output of the comparator 47 is switched from OV to a high impedance state, the input voltage of the positive input terminal of the comparator 47 rises from VB1 to VB2. The resistance value of the resistor 55 is set so that once the voltage of the battery 13 drops below 1.9V, even after the voltage of the battery 13 returns to more than 1.9V, when the output of the buffer amplifier 50 is switched from OV to 1.5V, the comparator 47 The input voltage of the negative input terminal still does not exceed VB2 »Therefore, once it is detected that the voltage of the battery 13 drops below 1.9V, the output of the comparator 47 constituting the voltage drop signal output member 16 continues to maintain a high impedance state. When the output of the comparator 47 becomes a high impedance state, the input voltage of the buffer amplifier 61 is switched from 0V to R53 / R54 · 1.5V (R53, R54 are the resistance values of resistors 53, 54), and the buffer amplifier 61 is boosted by the resistor 62 The output is switched from OV to a logic high level. As a result, a logic high level signal (equivalent to the voltage drop signal of the present invention) is continuously output to the input port P0 of the CPU 30. .Installation-(#Xianwen read the note on the back if you fill in this page), ιτ Γ The size of the paper is applicable to the Chinese National Standard (CNS) Α4 specification (210X297 mm) -13- Central Government Bureau of the Ministry of Economic Affairs Industrial and consumer cooperatives printed A7 B7 _.

Description of the invention (11) In addition, when the micro switch 20 is turned OFF and the power supply to the voltage drop signal output circuit 16 is cut off, the voltage drop signal output member is released 16 continues to output a voltage drop signal to the CPU 30. The AND element 57 constitutes a prohibition operation circuit 15 together with the voltage detection IC 48, the inversion elements 56, 58, resistors 59, and the capacitor 60. When the voltage detection IC48 detects that the voltage of the battery 13 drops below 1.9V, and the output of the voltage detection IC48 is switched from a high-impedance state to 0V, the output of the inversion element 56 is switched from 0V to a logic high level. At this time, since the output of the buffer amplifier 61 is at a logic high level as described above, a voltage of a logic high level is input to both input terminals of the AND element 57. Therefore, the output of the AND element 57 becomes a logic high level, and a logic low level signal (reset signal) is output from the inversion element 58. That is, when the voltage of the battery 13 falls below 1.9V, the operation circuit 15 to the CPU 30 are prohibited. The output level of the reset terminal is switched from a logic high level to a logic low level, and the operations of the CPU 30 and the control circuit 14 constituted by the CPU 30 are prohibited. . After the operation of CPU30 is disabled, the output ports Pi, P2, and P3 of CPU30 ~ 1 > 6 and? The output of 9 will become a logic high level, so the transistors 31 and 32 are turned off, the current to the coil 9 is cut off, the safety valve 3 shown in Fig. 1 is closed, and the gas burner 1 shown in Fig. 1 is turned off. Since the operation of the CPU 30 is prohibited, the malfunction of the CPU 30 can be prevented. Second, if the igniter 26 is operated with the voltage of the battery 13 falling to around 2.2V, for example, the voltage of the battery 13 may become 1.9V or less instantly. At this time, as described above, from the voltage drop signal output member 16 to the CPU 30 (please read the precautions on the back to fill in this page). Order the paper size of the paper.

Input port of invention description (12)? 0 Outputs a voltage drop signal at a logic high level, and at the same time outputs a logic low level reset signal " to the reset terminal of the CPU 30 by the prohibited action circuit 15 to prohibit the operation of the CPU 30. At this time, after the igniter 26 stops operating, the battery 13 When the voltage returns to a level exceeding 1.9V, the output of the forbidden action circuit 15 is switched from a logic high level to a logic low level. Therefore, the prohibition of the CPU 30 is released, and the CPU 30 starts to operate again. On the other hand, from the voltage drop signal output circuit 16 to the input port P0 of the CPU 30, the voltage drop signal is output as described above. Therefore, when the CPU 30 starts to operate again, by confirming whether the voltage drop signal is input to the input port PG by the voltage drop signal round-out member 16, before the operation starts again, it is determined whether the voltage of the battery 13 becomes less than 1.9V. If there is an input voltage When the signal is lowered, it can be imagined that the remaining life of the battery 13 is short, so the CPU 30 makes the replacement battery indicator 24 light up, and at the same time makes the buzzer 22 sing, which strongly urges the user to replace the battery 13. Therefore, even before the CPU 30 starts to operate again, the voltage of the battery 13 is restored from 1.9V to more than 2.2V, and when the first notification and the second notification are not performed, the CPU30 can still be used to urge replacement. Notification of battery 13.
