Field of the Invention The present invention relates to a combustion apparatus using a nickel-cadmium storage battery as a secondary power supply. 2. Description of the Related Art A nickel-cadmium storage battery (hereinafter referred to as a nickel-cadmium storage battery) is a microcomputer for a combustion device such as a rice cooker or a table stove when a primary power source is an AC power supply and a combustion switch is OFF. In the case where a thermoelectric generator such as an integrated thermocouple is used as a primary power source, or a thermoelectric generator such as an integrated thermocouple is used as a primary power source, these are used as secondary power sources to secure a power source at the start of the apparatus. [0003] Nicad storage batteries include:
If charge and discharge are repeated at an incomplete discharge depth, a memory effect may occur in which the battery capacity is reduced, and thus the use efficiency of the NiCd storage battery is reduced. In order to recover this memory effect, it is necessary to completely discharge the battery every time it is charged before charging it.However, this will waste the stored energy, and it will also take a long time to charge the device, resulting in deterioration of the function of the device. I will be connected. Accordingly, the present invention provides a combustion apparatus capable of effectively preventing the memory effect described above. discharge depth, the nickel-cadmium蓄 by times of operation
The present invention is characterized in that the battery is used with a battery capacity that is 1% or less of the battery capacity of the battery . Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram of a table stove 1. A gas supply pipe 3 for a gas burner 2 is provided with a magnet solenoid valve 4 for opening and closing a gas flow path. The electrode 5 and the thermocouple 6 are arranged. A control unit 7 for controlling these components includes a coil 8 for holding the magnet electromagnetic valve 4 open, an igniter 9 for sparking the ignition electrode 5, a reactor (not shown), a diode, a capacitor, and the like.
Booster circuit 1 that obtains thermoelectromotive force and supplies power to coil 8
0, and a NiCd storage battery 11 is provided as a secondary power supply for these circuits. Further, on the output side of the nickel-cadmium storage battery 11, a combustion switch 12 is provided.
The ignition switch 13 is provided on the input side of the igniter 9.
And on the input side of the coil 8 the combustion switch 1
2 are provided, respectively.
Reference numeral 15 is a resistor, and reference numerals 16 and 17 are diodes. Therefore, during the ignition operation of the table stove 1, when the combustion switch 12 is turned on together with the interlocking switch 14 and the ignition switch 13 is pushed down (turned on), as shown in the time chart of FIG. Power is supplied to the circuit 10 and the coil 8 respectively. Therefore, the magnet solenoid valve 4 opens to supply gas to the gas burner 2, and the igniter 9 operates to spark the ignition electrode 5 and burn the gas burner 2. After 5 seconds, the ignition switch 13 is released and the operation of the igniter 9 is stopped. After that, the booster circuit 10 that obtains the thermoelectromotive force of the thermocouple 6 that senses the flame of the gas burner 2 is
Power is supplied to the coil 8 after about 20 seconds, and the current supply from the NiCd storage battery 11 is stopped 30 seconds after ignition.
When the output of the booster circuit 10 becomes larger than the sum of the voltage of the NiCd storage battery 11 and the voltage of the diode 16, a charging current is supplied from the booster circuit 10 to the NiCd storage battery 11. When the fire extinguishing operation is performed, the combustion switch 1
2 and the turning off of the interlocking switch 14, the supply of the current to the coil 8 and the charging current to the NiCd storage battery 11 is stopped, and the magnet solenoid valve 4 is closed. [0006] Here, the amount of discharge consumed during one combustion of the table stove 1 is determined by the NiCd storage battery 1.
The capacity is set to be 1% or less of 1 capacity. That is, while the discharge amount at the time of the ignition is several mAh,
The capacity is more than 00 mAh. With this setting, the depth of discharge can be made extremely small, the occurrence of the memory effect can be suppressed, and the cycle life (number of charge / discharge cycles) of the NiCd storage battery 11 can be extended. Hereinafter, the setting in this embodiment will be described more specifically. [0007] The timing chart of FIG. 2 also shows the amount of electricity used at each load of the table stove 1 at one time.
0.111mAh when operated for 5 seconds with mA, magnet solenoid valve 4
Is for 10 seconds at 10 mA from the time of ignition until 20 seconds after that
5mA, 0.036mAh when it gradually decreases to 0 in 10 seconds, and the booster circuit 10
3mA for second, 0.021 for operation that becomes 0 in 10 seconds from there
It is the amount of mAh used. When these are summed, the amount of electricity required for one ignition = (0.111 + 0.036 + 0.021) = 0.
168 mAh, 0.028% of the 600 mAh NiCd battery
It becomes. FIG. 3 shows a change in the battery capacity of the NiCd storage battery 11 in a time chart of charge and discharge. The battery capacity decreases due to spontaneous discharge even when the table stove is not used. The amount of spontaneous discharge is 0.125 mAh, assuming 0.5% per day,
This is 0.021% of the Ni-Cd battery of 0 mAh. Here, since the charging current is 10 mA, assuming that the ignition operation shown in FIG. 3 is performed 10 times a day and combustion (simultaneously charging obtained from the booster circuit 10) is performed for 10 minutes, the discharge amount is (0.168 mAh × 10 ) + (0.125 mAh x 24) = 4.68 mAh The charge amount is (10 mA x 600/3600 x 10) = 16.667 mAh. Thus, if the battery capacity of the NiCd storage battery 11 is 600 mAh, the charge / discharge depth becomes extremely small by supplementing the natural discharge amount + the discharge amount at the time of ignition with a charge current of 10 mA even if charging and discharging are repeated as shown in FIG. , 99%, which is not less than 100%. In particular, here, since the discharge amount at the time of ignition is substantially equal to the spontaneous discharge amount, it is almost the same as maintaining the trickle charge state (a state of constantly charging with an electric amount close to the spontaneous discharge amount). That is, the memory effect is less likely to occur. Further, the ratio of the discharge amount to the capacity of NiCd storage battery, because they were less than 1%, prevention of the memory effect is performed more effectively, also a measure of the battery capacity determination. In the above-described embodiment, the nicd storage battery is described as a form in which a thermoelectric element such as a thermocouple is used as a primary power supply as a rising power supply of a table stove. The present invention is applicable to a combustion device used for a power supply. As described above, according to the present invention, a nickel-cadmium storage battery as a secondary power supply is provided with a charge / discharge depth of 1% or less of the battery capacity of the nickel-cadmium storage battery by one operation of the combustion device. By using the battery with a certain battery capacity, the occurrence of the memory effect can be more reliably prevented, and the cycle life of the nickel-cadmium storage battery can be suitably maintained. Special
The ratio of the discharge amount to the capacity of the NiCd storage battery is 1%
Because you are following, it is also a measure of the battery capacity determination.
