はその数が火力強より火力小になるので点灯数が減る。In the above embodiment, when the ignition button 34, which is the keyboard of the operation panel 28, is pressed, a control signal is input to the electronic control unit 31. Then, the solenoid valve 64 is opened by the signal from the electronic control unit 31, and the signal is sent to the gas control unit 30,
The motor 42 rotates, and at the same time, the closure 40 and the gas flow rate control body 43 work together. Then, the closing member 40 is opened, and the gas is matched with the closing member 40 and the gas outlet 39 of the gas flow rate control body 43, that is, the gas passage hole 43a or the control hole 4 which is a hole at that time.
It is supplied to the gas burner 60 (in this case, the stove 22 on the left side) from the nozzle 59 through any of 3b to 43g, and is ignited and burned by the spark of the igniter 61 which is operated by the signal from the electronic control section 31. Then, when the user wants to adjust the heat power, for example, the one which was pushed first was the heat power large / ignition button 34, so when the heat power small / ignition button 33 is pressed, a control signal is input to the electronic control unit 31, while The rotation angle of the gas flow rate control body 43 up to now is the rotation position detector 4
9 and the electronic control unit 31 is notified of this. However, since this position detection is different from the position where the thermal power is reduced to a low level, a signal is sent from the electronic control unit 31 which has confirmed this to the motor 42 to reduce the thermal power. The motor 42 rotates through the closure 40 as the gas flow rate control body 43 rotates at a predetermined angle to adjust the heat power to a small level. Of course, if the gas flow rate control body 43 rotates to a predetermined position, the power supply to the motor 42 stops. Also, at this time, the combustion display lamp 35a
The number of lights will decrease because the number of lights becomes smaller than that of strong heat.

If is pressed, the electronic control unit 31, the motor 42 are operated in the same manner as described above.
And a signal of the position of the gas flow rate control body 43 and the closing member 40 from the rotational position detector 49 is transmitted to the electronic control unit 31.
The electronic control unit 31 rotates the motor 42 to close the closing member 40. In addition, the electronic control unit 3
The solenoid valve 64 is closed at the time of the power failure of the power source No. 1 to prevent gas leakage at the time of re-energization.

せて閉子４０を閉じることもできる。In the description of the above embodiment, only ignition, fire extinguishing, and thermal power adjustment are performed, but since the gas flow rate is opened, closed, and regulated electrically in this way, the temperature of the pan bottom placed on the stove is detected as necessary. It is also possible to provide a sensor 75 for detecting the completion of cooking, detect an abnormally high temperature, send a signal for preventing tempura fire to the electronic control unit 31, and rotate the motor 42 to close the closure 40.
このように実施例では従来手動で行なっていたガスコッ

ス流量制御体の組合せで自動化したので、各種安全装置
の組合せもセンサ等をつけ加えるだけで簡単にできる。As described above, in the embodiment, the gas cock opening / closing and the thermal power adjustment, which were conventionally performed manually, are automated by the combination of the electronic control unit, the motor, the cock, and the gas flow rate control unit. Easy to do.
また、ガス供給と停止は一般的な弁方式と異なりコック
式なのでガス遮断の安全性も高い。Also, unlike the general valve system, the gas supply and stop is a cock system, so the safety of gas shutoff is high.
さらにモータ４２、閉子４０、ガス流量制御体を同一軸
上に設定し、そして回転方向のみの力が伝達できるよう
に連結しているので、部品点数も少なく、信頼性も高く
コストも安価にできる。Furthermore, since the motor 42, the closure 40, and the gas flow rate control unit are set on the same axis and are connected so as to transmit the force only in the rotational direction, the number of parts is small, the reliability is high, and the cost is low. it can.
さらにまたガス流量制御はガス流量制御体４３の制御孔
を必要数あけることにより流量変化が任意にえられ便利
である。Furthermore, the gas flow rate control is convenient because the flow rate can be arbitrarily changed by opening a necessary number of control holes in the gas flow rate control body 43.

する。As described above, according to the present invention, the electronic control unit that sends a signal for controlling the combustion unit, and the plurality of gas controls that operate by the signal from the electronic control unit and control the gas supply to the combustion unit and the flow rate thereof And a plurality of keyboards that are connected to the electronic control unit and that input a control signal, the gas control unit includes a motor, a cock that is driven by the motor and that opens and closes a gas passage, and a gas flow rate control body. It is composed of the cock, a control position detector of the gas flow rate control body, and an electromagnetic valve provided upstream of the plurality of gas control units, and has the following effects.
(1) 電気信号によりモータを駆動してガス制御部を制
