【発明が解決しようとする課題】しかしながら上記の従
来例にあるような構成では下記に示す課題があった。However, the configuration as in the above-mentioned conventional example has the following problems.
【0006】(1)従来の火力調節方法は、火力調節用
ニードル16火力を調節するか、電磁弁による強弱切り
換え燃焼のみで、燃焼量を計測し制御し供給ガス圧の変
動があっても燃焼量を一定に制御する事が出来なかっ
た。従って供給ガス圧の許容範囲には非常に幅があり、
例えば13Aガス種の場合、最低ガス圧は100mmH2
O、中心ガス圧200mmH2O、最高ガス圧250mmH2
Oと基準化され、火力の絞りは100mmH2O時でも失

温度調節時、温度調節弁によって強火弱火燃焼を生じさ
せるため急激な炎の変化があり使用者に不安感を与える
と同時に、強弱燃焼時間の差による火力制御を行う場
合、弁の作動音が頻繁になり耳障りであった。(1) In the conventional thermal power control method, the thermal power is adjusted by adjusting the thermal power of the thermal power control needle 16 or by switching the strength of the solenoid valve. It was not possible to control the amount to a constant level. Therefore, the allowable range of supply gas pressure is very wide,
For example, in the case of 13A gas type, the minimum gas pressure is 100mmH 2.
O, central gas pressure 200 mmH 2 O, maximum gas pressure 250 mmH 2
It is standardized as O, and it is necessary to secure the thermoelectromotive force of the thermocouple in order to prevent misfire even when the throttle of the thermal power is 100 mmH 2 O, and the thermal power throttle that always considers the safety factor of 40% cannot be fully throttled. The result was to provide. In addition, during automatic temperature control, the temperature control valve causes a strong flame and a low flame combustion, which causes a sudden flame change and makes the user feel uneasy.At the same time, when controlling the thermal power due to the difference in the strong and weak combustion times, the valve is activated. The sound was so frequent that it was offensive to the ears.
【0007】(2)圧力センサーを使用した場合、圧力
センサーが故障しガス漏れが発生すると、器具内に生ガ
スが放出され器具火災になる恐れがあるがこれを防ぐ手
段がなかった。(2) When a pressure sensor is used, if the pressure sensor fails and a gas leak occurs, raw gas may be released into the device and cause a device fire, but there is no means for preventing this.
【0008】(3)また流量制御手段の機構部に異物が
付着した場合、絞り機構の異常隙間により、小燃焼量に
絞りきれない場合があった。(3) Further, when foreign matter adheres to the mechanical portion of the flow rate control means, it may not be possible to reduce the combustion amount to a small amount due to an abnormal gap in the throttle mechanism.
【0009】(4)従来の器具に於いては、供給ガス圧
異常(LPGボンベの空、ゴム管折れ、ガス元栓の半開
き等によるガス供給能力不足)の検出機能がないため、
例えばこんろ一口は使用出来るが2口使用すると火力が
弱い、点火するがすぐ消える等、の簡単な事象であるが
使用者が容易に発見できなく、サービスコールが発生す
ることが多々あった。(4) Since the conventional equipment has no detection function for abnormal supply gas pressure (insufficient LPG cylinder, broken rubber tube, insufficient opening of the gas main plug, etc.),
For example, a single stove can be used, but if two stoves are used, the fire power is weak, and although it is a simple event such as ignition, but it disappears immediately, the user cannot easily find it and a service call often occurs.

る。(5) Further, in the case of adjusting the pressure while detecting the pressure with the gas pressure sensor, the rough adjustment and the fine adjustment are performed by the correlation between the adjusting accuracy and the ability of the throttle mechanism and the gas pressure detecting ability. If the time for adjusting the heat power is not shortened, it is necessary to consider that the food will boil and spill over.
【0011】(6)また、従来のガス器具に於いては、
供給ガス圧変動が大きくガスの種類によっては標準ガス
圧と最大ガス圧では約40%も変化するため、器体の異
常温度上昇による火傷、ガス圧異常による異常燃焼など
が生ずる危険性があった。(6) Further, in the conventional gas appliance,
Since the supply gas pressure fluctuates greatly and the standard gas pressure and the maximum gas pressure change by about 40% depending on the type of gas, there is a risk of burns due to abnormal temperature rise of the body and abnormal combustion due to abnormal gas pressure. .

不慣れな作業を行うとガス漏れの危険がある。また、交
換まちがえによる不良が発生する。(7) In the conventional two-necked gas stove, generally, a small burner with a combustion amount of about 2000 Kcal / h and 400
A large burner of about 0 Kcal / h is installed. The minimum combustion amount of these burners is 400 Kcal / h and 500 K, respectively.
If you squeeze it more than about cal / h, no flame will be formed and it will extinguish. Therefore, the heat power adjusting needles are divided into small and large ones. Therefore, at the time of gas type conversion,
Since it is necessary to disassemble the interior of the gas cock and replace parts,
Performing unfamiliar work may cause gas leaks. In addition, a defect occurs due to a mistake in replacement.

必要とし、ガス種転換費用も高価になるなどの欠点があ
った。(8) Further, the above-mentioned minimum combustion amount is not constant because the combustion speed differs depending on the gas species and the calorific value differs. Therefore, a needle that determines the minimum combustion amount for each type of gas type burner is required, and many gas conversion parts,
Need assembly parts. Therefore, when exchanging gas species, it is necessary to remove the gas mechanical block, skill is required from the viewpoint of preventing gas leakage accidents, more time is required, and gas species conversion costs are high. there were.

使用始めに0点調整を行い得るが、ガスこんろの場合使

ら使用者に調整させる事はできない。(9) When measuring the combustion amount with a pressure sensor, which has never been used before, when using it as an industrial measuring instrument,
It is possible to make a zero point adjustment at the beginning of use, but in the case of a gas stove, it is dangerous for the user to ask the user to make an adjustment because the person who is the symmetric person may be an old person or a child, and if the setting is incorrect, it may cause poor combustion. It cannot be adjusted.
【0015】(10)従来の器具にはなかった圧力セン

く使いにくくなる。(11) If the performance of the pressure sensor, which was not present in the conventional equipment, deteriorates and the performance of the equipment cannot be guaranteed if it is used as it is, the heat power cannot be adjusted and it becomes more difficult to use than the conventional equipment.

コストも高価となる。(12) When one of the plurality of stove burners fails and becomes inoperable, it is preferable to provide a safety device for each burner to shut off the gas. A large number of burners are required in proportion to the number of burners, and the production cost is high.

If the heat power is adjusted individually, it takes time, and for example, if the power throttle is required in the state where the later stove is boiling, it will be spilled.

なる。(14) When the performance of the pressure sensor is to be confirmed with a device using a pressure sensor which has not been found in conventional devices, for example, a special confirmation tool is required at the time of manufacture.
It takes extra man-hours to attach and remove tools, and it is a general household appliance at the time of servicing, and it takes time for the treatment without the service person always carrying the tool around.

The value of the error is taken into consideration, and the purpose of use will be described later. The minimum set gas pressure 114 is proportional to the minimum combustion amount of the burner 1, and Q = Ж × D ^ 2 × H / d Q = gas flow rate Ж = coefficient determined for each type of gas D ^ 2 = gas passage area H = gas pressure d = specific gravity determined for each type of gas Also, the minimum combustion capacity of the burner 1 changes depending on the unique characteristics of the burner and each gas group, and if the combustion amount is made too small, the combustion load is too small to extinguish the fire. Since problems such as backfire will occur in the above, the minimum set gas pressure for each gas group is set to 1 for each gas group from the experimental values so that problems do not occur.
14 is set. The abnormal supply gas pressure 115 is a value obtained by subtracting an error of the pressure sensor 86 or the like from the minimum gas pressure of each gas group defined by law. The purpose of use will be described later. Further, since the minimum calorie of each burner is determined by the weak calorie correction means 117, the maximum of each burner set by the burner calorie switching means 117 (in the present invention, it is assumed that the two modes are large and small) is set. It is determined 118 whether the calorie at the time of combustion is large or small, and when the determination is large, the minimum combustion amount is set high in comparison with the minimum combustion amount of the small burner to prevent extinction. Therefore, the minimum set gas pressure 114 is multiplied by the gas pressure correction coefficient α to set 119, and the minimum set gas pressure is set to high 12

め、器具の故障を防止する効果を有している。Similarly, as shown in FIG. 4, the flow rate control means of the flow rate control means is provided with a geared motor, a relay joint which also serves as a switch cam for converting rotational movement into reciprocating linear movement via a serration shaft of the geared motor, and a spiral slit. It is composed of a bearing, a shaft that performs a reciprocating linear motion with a pin at the tip to be inserted into the bearing, a switch A, and a switch B. Since a relay joint is used, special attention is required for parts accuracy and assembly accuracy. It has the effect of preventing malfunctions. Further, although the valve is pushed up by the shaft that performs the reciprocating linear motion to form a gas flow path, the switch A for stopping the gad motor in a state where there is a gap between the shaft and the valve in the stopped state of FIG. Since it is configured by B, there is an effect that it is securely closed and at the same time, high precision of parts is not required. Further, a switch cam is provided in the relay joint, and by combining with the switches A and B,
Stop, move, maximum thermal power, thermal power adjustable position, and maximum operating point position can be identified, so even if the power is restored, it is possible to immediately restore to the stopped position, and at the maximum thermal power, set to the minimum flow loss position, It informs the drive determination means that it is within the range of adjustable heat power, and even if the needle is pressed against the needle receiver due to the stop position deviation due to the shock absorber at the maximum operating point,
Since the gad motor can be stopped without being overloaded, it has the effect of preventing equipment failure.

In this bypass nozzle, even if the gas pressure sensor is damaged, even if there is a slight gas leak, the flow rate regulated by the bypass nozzle causes the sensor pressure to drop extremely, making it easy to detect as a gas pressure abnormality at the same time. Even if the gas pressure sensor is damaged and a large amount of gas flows out, there is an effect that it is limited to a very small amount of gas leakage regulated by the bypass nozzle and is not dangerous.

る。As shown in FIG. 8, the shape of the needle portion is not a single taper but a plurality of cylindrical or conical steps, and flow rate control is adjusted by a combination of area change and flow velocity resistance change. In other words, the composition is divided into the low Wobbe gas adjustment zone and the high Wobbe gas zone adjustment, but this means that when the minimum thermal power is assumed to be 400 Kcal / h, for example, the gas flow rate at the minimum thermal power corresponding to the domestic gas type Is different depending on the amount of heat generated by each gas type, and the setting of the supply gas pressure also differs depending on the gas type.Therefore, when a needle with a single taper shape is used, the trajectory of the needle stroke and gas pressure state is adjusted in the case of propane gas, etc. Since the minimum operating gas pressure and the maximum operating gas pressure coexist in the movable range where the pressure stroke range is extremely small, the pressure regulation value cannot be determined due to the correlation between the mechanical accuracy of the drive unit and the calculation processing speed of the gas pressure detection means. Occurs. In order to solve these problems, a certain pressure adjustment stroke range is secured for any gas type, and the minimum calorie restriction of LPG, which has the maximum heat generation amount per unit volume, is specially the minimum flow restriction hole in the needle receiver. With the provision of, it is possible to manufacture the needle part with rough precision, pressure adjustment can be easily performed, and mass production effect can be expected.

ったため従来の問題点を解消することが可能となった。FIG. 10 shows a gas type setting means. Conventionally, when the gas type is switched, the gas pressure of the needle for controlling the minimum flow rate, the bypass key, and the governor is changed.
There are factors such as erroneous insertion of parts and defective gas seals, and at the same time, many parts need to be replaced, so replacement costs were high. Further, since the value of the minimum thermal power also changes depending on the value of the maximum thermal power, a flow rate control means corresponding to the value is required. For example, in the case of a two-mouth stove, when combined with a gas type, 16 types of flow rate control means were required. In the present invention, since the gas type and the calorie setting are switched, it can be shared by one flow rate control means, and since it is not necessary to touch the flow rate control means, the conventional problems can be solved.

に合わせる事が可能となる特長を有している。FIG. 12 shows the gas pressure judging means.
Since the gas pressure that correlates with the flow rate of the main nozzle is measured, it is possible to control the thermal power. Therefore, in the past, in order to secure the thermoelectromotive force of the thermocouple for sustaining combustion even with the lowest supply gas pressure, at the supply standard gas pressure, it was necessary to set the calorie value as high as 40% in 13A. It was In the present invention, the gas pressure near the main nozzle (secondary pressure)
The minimum calorie is 4
Even if the pressure is up to 00 Kcal / h, the minimum set gas pressure can be controlled to be constant according to the present invention, so 400 × 0.6.
= 240Kcal / h has been theoretically narrowed down. Also, since the middle calorie is set based on the gas pressure of the minimum calorie, even if the supply gas pressure fluctuates somewhat,
Since the heating power that is close to the set heating power can be obtained at any time, the reproducibility of the cooking time can be secured, the reliability of the cooking timer is improved, and it is extremely easy to use for egg dishes etc. that require minute calorie control depending on the food. Can be improved. The thermal power is adjusted by adjusting the secondary pressure to the gas pressure of the set thermal power. Therefore, depending on the difference between the target pressure value and the secondary pressure, the pressure adjustment is completed within a certain range, and the pressure is adjusted. When the difference is small, the driving speed of the flow rate control means 100 is changed depending on the size of the difference, and when the difference is small, the driving speed is accurately adjusted to the target heating power at a low speed. When the number is large, the driving speed is made high so that the target heating power can be quickly approached. Therefore, it has a feature that it can respond quickly when urgently squeezing the fire power such as spillage, and can adjust the target calorie accurately by slowing down the speed during fine pressure adjustment.

By setting the state and confirming the transition of each step, switch failure is confirmed and safety is secured. At the same time, it has the purpose of changing the speed of the flow rate control means 100 according to the difference between the transition target position and the current position to reach the position quickly and accurately, and has the role of determining the traveling direction of the drive device by the sign of the difference. ing. Further, even when the secondary gas pressure does not reach the target pressure adjustment at the time of the minimum throttle, it has a role of forcibly stopping and preventing the destruction of the mechanism. It also has the role of clarifying the position by checking the gas pressure sensor when the switch position is in the stopped state and checking the supply gas pressure for abnormalities when the thermal power is at the maximum value.

Generally, it is unlikely that the supply gas pressure will be lower than the legal gas pressure, and in most cases it is due to the half-opened state of the instrument main plug in the room, twisting of the rubber pipe, breakage, etc. Depending on the burning equipment, incomplete combustion may result in gas poisoning, or the equipment may not be fully used. The present invention has an effect of issuing an alarm to notify and cancel the alarm when these events occur.

However, since the gas pressure sensor part in the stopped state is open to the atmosphere via the main nozzle, it is in the stopped state. By measuring the secondary gas pressure, discriminating the error when the gas pressure is 0, and compensating when the difference from the reference value is within a certain range and compensating, the manufacturing error of the gas pressure sensor can be absorbed and incorporated at low cost. In addition, error due to aging change can be minimized, accuracy can be maintained, and if there is a large difference from the reference value, an alarm is issued to prompt the need for inspection, and the difference from the reference value In the event of an extreme occurrence, it has a self-check function to stop the equipment for safety, and it has the effect that it can be used safely and safely with high accuracy.

Conventionally, a governor has been used, and it is necessary to change the set value of the governor at the time of gas type conversion, and the flow rate loss due to the governor causes a combustion state. There was a problem in setting the combustion conditions because there was a difference in the conditions, especially in the state where it was difficult to use for a stove burner, etc., and there was a case that the temperature of the equipment increased excessively at abnormal gas pressure. In the present invention, since the secondary gas pressure in the vicinity of the nozzle is controlled to be constant without using a governor, the burner combustion characteristics are the same as the conventional one, no special consideration is required, and it is always constant with respect to the set thermal power. It has the effect of obtaining the firepower of.

ある。In FIG. 21, the temperature of the temperature sensor is detected,
In the invention relating to the temperature detection of the temperature sensor used for the purpose of preventing the tempura fire in which the oil temperature becomes abnormally high and the oil ignites, the control circuit detects the short circuit or open state of the temperature sensor as in the example shown in FIG. Therefore, in consideration of safety, the input end of the temperature sensor is input to the microcomputer (central control means) in two systems of A and B, even if one end should fail, the other end detects it. Is done V1
The fact that the voltage at the point becomes 0 V or Vcc (power supply voltage) when the circuit is short-circuited or open is used to ensure safety in the event of a sensor failure. However, this method cannot detect the intermediate potential failure of the temperature sensor (for example, if the simulated resistor R1 is added to the temperature sensor, the resistance change becomes very small, and the temperature of the pot bottom temperature is not accurately detected.) Unsafe side It will work. In order to solve this problem, it is necessary to detect the state of 4 (temperature sensor temperature at unsafe side failure) as shown in FIG. This 4 curve has very little temperature rise regardless of oil or water. However, if only the temperature rises are compared, for example, in the case of high-load cooking when the thermal power is at a minimum, the same curves are obtained, and the result is that good products are also determined to be defective. In the present invention, in order to solve this problem, as a method of confirming that the maximum thermal power has passed a certain time, the maximum thermal power setting position, the method of confirming the current position determination means, and the maximum thermal power by the gas pressure determination means The secondary gas pressure is set to either of the above two methods, and the temperature sensor is configured to judge whether the temperature sensor is good or bad based on the temperature and temperature gradient, and a safe and highly reliable temperature sensor failure determination method is used. It is intended to be incorporated into.

急激な炎の変化が少なく不安感を与えない。(1) By detecting the gas pressure by the gas pressure determination means and adjusting the pressure by the flow rate control means so that the set gas pressure set by the heating power setting means is always maintained, the set heating power is lowered particularly at low setting heating power.

The result of h was squeezed to 300 Kcal / h, and it is possible to retain heat that could not be done in the past. Further, since the throttle mechanism can be constituted by a needle mechanism, a proportional valve, or the like, unlike a solenoid valve, there is little sudden change in flame, and there is no anxiety.

常早期発見が可能となる。(2) By adding a flow rate regulating device to the gas inflow portion of the pressure detecting portion, the amount of gas leakage when the pressure detecting portion is damaged is regulated. Also, if there is a minute gas leak, the measured value may indicate that the gas pressure is abnormal, and if the pressure detection unit is damaged, gas leakage may occur, causing a fire in the vessel. By installing a device, the amount of leakage is very small, and it is possible to prevent danger, and even if it is a minute gas leak due to minute destruction of the pressure sensing part, there is a regulated gas amount of the flow rate control device, so the gas pressure drops at the pressure sensing part. Since the gas pressure determination means determines that the gas pressure is abnormal, it is possible to detect the abnormality early.

In this case, the throttling mechanism does not stop the throttling motion until the pressure reaches a predetermined pressure, and finally, it is determined that the throttling mechanism is defective, and the stopping of the device is prevented, and an unreasonable load is applied to the throttling mechanism.

火等が発生しない。(5) By varying the drive speed of the flow rate control means by the drive speed determination means, for example, when switching from high heat to low heat, the speed is increased to just before low heat, and when finely adjusting to the set gas pressure, the speed is decreased. As a result, when weakening the heat power after boiling, it is possible to rapidly squeeze,
When finely adjusting the pressure, adjust slowly so that it is not over-throttled and fire will not occur.

By adjusting the maximum heating power at the time of gas pressure, the temperature rise of the body overheating is low, and the electronic circuit inside the body is not exposed to the abnormally high temperature atmosphere, so the risk of burns is reduced and the cause of equipment failure is also reduced. .

When changing the position of the middle calorie burner, the set gas pressure value corresponding to the burner capacity can be changed without changing the throttle mechanism. Since it is not necessary to replace the needle of the conventional throttling mechanism, the number of replacement parts can be reduced. Further, since the gas block that causes gas leakage is not disassembled, safety is secured and the replacement time can be shortened. In addition, the position change of the large burner and the middle burner is also compatible with the changeover of the switch, which has the same effect.
