【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

湯沸かしで使用されているが、電力を常時必要とするた
め、調理器でも、卓上型のガステーブルでは、家庭用電
源を使用することは使用者の拒絶感が大きく商品化はで
きない実態である。[0006] (1) The conventional heating power adjustment method is to adjust the heating power of the heating power adjustment needle 16 or only to switch between strong and weak combustion using an electromagnetic valve. Did not. However, the gas proportional valve is
Although it is used as a water heater, since electric power is always required, the use of a household power source in a cooker or a table-top gas table is a situation in which the user has a great sense of refusal and cannot be commercialized.
【0007】また、自動温度調節時、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。In addition, when automatic temperature control is performed, the temperature control valve causes high-heat / low-fire combustion to cause a rapid flame change, giving a user an uneasy feeling. The operation sound of the valve became frequent and harsh.
【0008】(2)モーターを使用した流量制御装置
は、比例弁や、電磁弁の動作と比較し応答速度(例えば
強〜弱にガス量を変化させる場合)は非常に遅い。(2) The flow rate control device using a motor has a very slow response speed (for example, when the gas amount is changed from strong to weak) as compared with the operation of a proportional valve or an electromagnetic valve.

て指定位置になかなか止まらない、等の課題がある。When the position is confirmed, if the speed is abnormally high, it is difficult to stop at the designated position due to the bouncing of the contact terminals of the position detector and the processing speed of the microcomputer (including the software processing method). Issues.
【0010】また、ガス圧センサーで検圧しながら調圧

出能力の相関により、粗調整と精密調整の区分を行う等
して、火力調節時間を短くしないと調理物が沸騰して吹
きこぼれが発生するなどに対する配慮が必要となる。Further, when adjusting the pressure while detecting the pressure with a gas pressure sensor, the adjustment of the heating power is performed, for example, by making a distinction between a coarse adjustment and a fine adjustment based on the correlation between the pressure adjustment accuracy and ability of the throttle mechanism and the gas pressure detection ability. If the length is not shortened, it is necessary to take measures against boiling of the food and occurrence of spillage.
【0011】(3)ガスの閉止機能の向上を図り、閉止

っても閉止機能が確実となる必要がある。(3) It is necessary to improve the gas closing function, and to ensure the closing function even when there is backlash of the shaft of the motor driving part at the time of closing.

た、機構が破壊しない為の対策を必要とする。(4) In the configuration of the universal flow rate control means, in the minimum throttle state, unless the throttle mechanism is pressed, the minimum amount of gas flowing through the gap cannot be ensured, and measures must be taken to prevent the mechanism from being destroyed. I do.

【0014】(6)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100mmH
2O、中心ガス圧200mmH2O、最高ガス圧250mmH2Oと
基準化され、火力の絞りは100mmH2O時でも失火防止
のため前記熱電対の熱起電力を確保する必要があり、常
に40%の安全率を考慮した火力絞りが絞りきれない燃
焼器具を提供する結果となっていた。(6) The amount of combustion was measured and controlled, and even if the supply gas pressure fluctuated, the amount of combustion could not be controlled to be constant. 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
Standardized to 2 O, center gas pressure 200 mmH 2 O, maximum gas pressure 250 mmH 2 O, it is necessary to secure the thermoelectromotive force of the thermocouple to prevent misfiring even at 100 mmH 2 O. Therefore, the result is to provide a combustion appliance that cannot be fully squeezed by the thermal throttle taking into account the safety factor of 10%.
【0015】従来の器具に於いては、供給ガス圧異常

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。Since the conventional apparatus does not have a function for detecting an abnormal supply gas pressure (insufficient gas supply due to an empty LPG cylinder, broken rubber pipe, half-opening of the gas main plug, etc.), for example, one hot pot can be used. Although the use of two ports is a simple event such as low heat power, ignition but extinguishing immediately, the user cannot easily find it, and a service call often occurs.

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. 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 Further, the minimum combustion capacity of the burner 1 varies depending on the unique characteristics of the burner and each gas group, and if the combustion amount is made too small, the combustion load becomes too small to extinguish the fire. In this case, the minimum set gas pressure is set to 1 for each gas group based on the experimental values to prevent the occurrence of problems such as backfires.
14 is set. The abnormal supply gas pressure 115 is a value obtained by subtracting an error of the pressure sensor 86 and the like from the minimum gas pressure of each gas group defined by law. The purpose of its use will be described later. In addition, since the minimum calorie of each burner is determined by the weak calorie correcting means 117, the maximum burner of each burner set by the burner calorie switching means 117 (in the present invention, it is assumed that two modes are set, large and small). It is determined whether the calorie at the time of combustion is large or small 118. If the determination is large, the minimum combustion amount is set higher on the combustion characteristics of the burner as compared with the minimum combustion amount of the small burner to prevent fire extinguishing. Therefore, the minimum set gas pressure 114 is multiplied by the gas pressure correction coefficient α, and the minimum set gas pressure is set high 12.

め、器具の故障を防止する効果を有している。As shown in FIG. 4, the flow control means of the flow control means is provided with a relay joint which also serves as a geared motor, a switch cam for converting a rotary motion into a reciprocating linear motion via a serrated shaft of the geared motor, and a spiral slit. And a switch A and a switch B with a pin at the tip inserted into the bearing, and switches A and B. Special attention must be paid to parts accuracy and assembly accuracy through the relay joint. Therefore, there is an effect that a malfunction does not easily occur. In addition, the valve is pushed up by the shaft performing the reciprocating linear motion to form a gas flow path. At the time of the stop state in FIG. 4, the switches A and A are configured to stop the gad motor with a gap between the shaft and the valve. Since it is constituted by B, there is an effect that it is not necessary to have high precision in parts accuracy at the same time as closing securely. Also, a switch cam is provided on the relay joint, and in combination with switches A and B,
Stop, move, maximum thermal power, thermal power adjustable position, maximum operating point position can be determined, so even in the power failure recovery state, it can be immediately restored to the stop position, at the maximum thermal power set to the minimum flow loss position, It informs the drive determination means that the heating power is within the adjustable range, and at the maximum operating point, even if the stop position shifts due to the shock absorber and the needle is pressed against the needle receiver,
Since the gad motor can be stopped without overloading, it has an effect of preventing a failure of the device.

In the event of a gas pressure sensor being damaged and even a slight gas leak, the sensor pressure drops extremely due to the flow rate regulated by the bypass nozzle, making it easier to detect a gas pressure abnormality. In addition, even if the gas pressure sensor is damaged and a large amount of gas flows out, there is an effect that there is no danger because only a very small amount of gas leakage regulated by the bypass nozzle is generated.

る。As shown in FIG. 8, the shape of the needle portion is not formed into a single taper but is formed into a plurality of cylindrical or conical steps, and flow rate control is adjusted by a combination of an area change and a flow velocity resistance change. In other words, it is configured to be divided into a low wobbe gas adjustment band and a high wobbe gas band adjustment, but this means that when the minimum thermal power is 400 Kcal / h, for example, the gas flow rate at the minimum thermal power corresponding to the domestic gas type Depends on the calorific value of each gas type, and the setting of the supply gas pressure also differs depending on the gas type.If a single tapered needle shape is used, the trajectory of the stroke and gas pressure state of the needle will not be adjusted in the case of propane gas, etc. The minimum usable gas pressure and the maximum used gas pressure are mixed in the extremely small movable range of the pressure stroke range, and the result that the pressure adjustment value is not determined by the correlation between the mechanical accuracy of the drive device and the processing speed of the gas pressure detecting means Occurs. In order to solve these problems, a constant pressure adjustment stroke range is secured for any gas type, and the minimum calorie regulation of LPG, which generates the largest amount of heat per unit volume, is a minimum flow restriction hole in the needle holder. By providing, the accuracy of the needle part can be produced with a rough finish, the pressure can be easily adjusted, and the effect of mass production 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 changing the gas type, the gas pressure of the needle, bypass key and governor for regulating the minimum flow rate is changed.
There are factors such as erroneous insertion of parts, defective gas seal, and the like, and at the same time, many parts need to be replaced, so replacement costs are high. In addition, since the value of the minimum heating power also changes according to the value of the maximum heating power, a flow control means corresponding to the value is required. For example, in the case of a two-port cooker, 16 kinds of flow control means are required in combination with a gas type. In the present invention, the gas type and the calorie setting are switched, so that one flow control means can be used in common, and it is not necessary to touch the flow control means, so that the conventional problems can be solved.

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 order to secure the thermoelectromotive force of the thermocouple for sustaining combustion even at the lowest supply gas pressure, it is necessary to set the calorie setting at 40 A at the standard supply gas pressure as much as 40%. Was. In the present invention, the gas pressure near the main nozzle (secondary pressure)
Is controlled, for example, conventionally the minimum calorie is 4
Even at a pressure of up to 00 Kcal / h, the minimum set gas pressure can be controlled to be constant according to the present invention.
It was theoretically possible to narrow down to 240 Kcal / h. Also,
Since the calorie in the middle is set based on the gas pressure of the minimum calorie, even if the supply gas pressure fluctuates slightly, the thermal power close to the set thermal power is always obtained, so the reproducibility of cooking time can be secured. In addition, the reliability of the cooking timer can be improved, and the usability of eggs can be greatly improved for cooking dishes that require minute calorie control. Since the thermal power adjustment is a method of adjusting the secondary pressure to the gas pressure of the set thermal power, the pressure adjustment is completed within a certain width depending on the difference between the target pressure adjustment value and the secondary pressure, and the pressure adjustment is performed. Prevents being determined indefinitely, when the width is more than a certain width, changes the drive speed of the flow rate control means 100 depending on the difference, and when the difference is small, the drive speed is accurately adjusted to the target thermal power at a low speed,
When there is a large difference, the driving speed is increased so that the target thermal power can be quickly approached. Therefore, it is possible to quickly cope with a case in which it is necessary to reduce the heating power urgently, such as when spilling over, etc. In addition, when the pressure is finely adjusted, the speed can be reduced and the target calorie can be accurately adjusted.

By setting the state and confirming the shift of each step, the failure of the switch is confirmed and the safety is ensured. At the same time, the speed of the flow control means 100 is changed by the difference between the transition target position and the current position, the purpose is to quickly and accurately reach the position, and the role of determining the traveling direction of the drive device is determined 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 is forcibly stopped to prevent the mechanism from being destroyed. When the switch position is in the stop state, the gas pressure sensor is checked, and when the switch position is at the maximum heating power, the supply gas pressure is checked for abnormalities, and the position is clarified.

ある。FIG. 21 shows the operation of detecting the temperature of the temperature sensor.
In the invention relating to the temperature detection of a temperature sensor used for the purpose of preventing a tempura fire in which the oil temperature becomes abnormally high and the oil ignites, as shown in an example shown in FIG. 23, the control circuit detects a short circuit or an open state of the temperature sensor. Therefore, the input end of the temperature sensor is input to the microcomputer (central control means) by two systems of A and B so that even if one end breaks down, the other end detects it and the safety is considered. Is performed V1
Utilizing that the voltage at the point becomes 0 V or Vcc (power supply voltage) when the point is short-circuited or open, safety is ensured in the event of sensor failure. However, this method cannot detect an intermediate potential failure of the temperature sensor (for example, if the simulated resistor R1 is added to the temperature sensor, the change in resistance becomes very small, and the temperature of the pan bottom temperature is not accurately detected). It will work. In order to solve this problem, it is necessary to detect the state of 4 (temperature sensor temperature at the time of failure on the unsafe side) as shown in FIG. The curve of 4 has a very small temperature rise regardless of oil or water. However, if only the temperature rise is compared, for example, in the case of high-load cooking when the thermal power is at a minimum, the curves are the same and similar, and a good product is determined to be a faulty product. In the present invention, in order to solve this problem, as a method for confirming that the heating power has reached a predetermined time at the maximum, a method of checking the maximum heating power setting position by the current position determining means, and a method of confirming the maximum heating power by the gas pressure determining means. And a method to judge the quality of the temperature sensor based on the temperature and the temperature gradient, and a safe and highly reliable method of determining the failure of the temperature sensor. It is intended to be incorporated into.
