In addition, when the object to be heated is placed on the virtues 6 in this state, the upper end of the movable portion 13 is pushed down by the bottom of the object to be heated. The detection switch 15 is switched as the movable part 13 moves up and down. In other words, in a state where the object to be heated is not placed on the virtues 6, the movable portion 13 protrudes above the virtues 6 and the detection switch 15 is turned off, and when the object to be heated is placed on the virtues 6, the movable portion. 13 is pushed down by the object to be heated and the detection switch 15 is turned ON, thereby detecting whether or not the object to be heated is placed on the stove burners 3a to 3c.

  Further, a temperature sensor 16a is provided at the upper end portion of the movable portion 13 of each of the heated object detecting means 12, and the temperature detecting means 16 described above is constituted by the temperature sensor 16a. Each temperature sensor 16a contacts the bottom of the object to be heated placed on the corresponding virtues 6 and detects the temperature of the object to be heated in this state.

  Each of the standard burner 3a, the small burner 3b, and the high thermal power burner 3c is provided with a thermocouple 36a (see FIG. 7) as the above-described ignition state detecting means 36, and it corresponds based on the detection result of the thermocouple 36a. It is possible to determine whether or not the hot burners 3a to 3c are in an ignition state.

  Hereinafter, control of the light emission state of the light emission part 41 by a control means is explained in full detail.

  When the power switch 40 is in the ON state, the control means performs detection by the heated object detecting means 12 provided for each of the stove burners 3a to 3c, and as a result, the heated object is placed on the stove burners 3a to 3c. Is not disposed, and when the stove burners 3a to 3c are not in an ignition state, the light emitting portions 41 of the corresponding operation portions 8a to 8c are turned off.

  Further, when the heated object detecting means 12 detects that the heated object is disposed on the stove burners 3a to 3c and the stove burners 3a to 3c are not in an ignition state, the stove burner is used. The light emitting units 41 of the operation units 8a to 8c corresponding to 3a to 3c are caused to emit light in the white emission color to be in a lighting state.

  In this case, until the predetermined time (specifically, 30 seconds) elapses from the time when the object to be heated is arranged on the stove burners 3a to 3c by the to-be-heated object detecting means 12, The light emitting units 41 of the corresponding operation units 8a to 8c are turned on with a predetermined brightness. In addition, when the to-be-heated material on the stove burners 3a to 3c is moved to another place within the predetermined time, or when the stove burners 3a to 3c are ignited, the light emitting unit 41 is turned on in white. To turn off or turn orange.

  In addition, after the predetermined time has elapsed from the time when the object to be heated is placed on the stove burners 3a to 3c, the light emitting unit 41 emits light with a brightness lower than the predetermined brightness. The lighting state is maintained until the object to be heated on the burners 3a to 3c is moved to another place or until the stove burners 3a to 3c are ignited.

  Note that examples of a method for causing the light emitting unit 41 to emit light with a brightness that is darker than a predetermined brightness include reducing the duty ratio of the drive current of the light emitter 42 or reducing the drive current value of the light emitter 42.

  In addition, when the burners 3a to 3c are in an ignition state with the power switch 40 turned on, the operation units 8a to 8c corresponding to the burner burners 3a to 3c regardless of the detection result by the heated object detection means 12. The light emitting unit 41 of 8c is turned on by emitting light in an orange emission color.

  Further, when the stove burners 3a to 3c are automatically extinguished by the control in the automatic cooking mode when the stove burners 3a to 3c are in an ignition state, operations corresponding to the stove burners 3a to 3c are performed. The light emitting units 41 of the units 8a to 8c are blinked in white emission color. The white flashing of the light-emitting unit 41 can be turned off after a predetermined time (for example, 5 minutes) has elapsed from the time of extinguishing the stove burners 3a to 3c to save energy, but in this embodiment, In order to prompt the user to return the operation units 8a to 8c to the state instructing fire extinguishing, the operation units 8a to 8c continue to blink until the operation unit 8a to 8c is operated to return to the state instructing fire extinguishing.

  In addition, when the stove burners 3a to 3c are extinguished by the operation of the operation units 8a to 8c when the stove burners 3a to 3c are in an ignition state, the to-be-heated object detecting means 12 performs the stove burners 3a to 3c. When it is detected that an object to be heated is disposed on 3c, the light emitting unit 41 of the operation units 8a to 8c corresponding to the stove burners 3a to 3c is turned on in a light emitting state. When the object to be heated is not disposed on the stove burners 3a to 3c, the light emitting portions 41 of the operation units 8a to 8c corresponding to the stove burners 3a to 3c are turned off.

  In addition, when the above-described stove burners 3a to 3c are in an ignition state, the abnormality detection means extinguishes the mid-burner burners 3a to 3c and the heated object disposed on the stove burners 3a to 3c becomes hot. When detected, regardless of the detection result by the heated object detecting means 12, the gas supply to the stove burners 3a to 3c is forcibly stopped as described above, and the stove burners 3a to 3c are stopped. The light emitting units 41 of the corresponding operation units 8a to 8c are blinked in orange light emission color. In addition, after extinguishing the stove burners 3a to 3c due to the abnormality detection, the light emitting unit 41 is blinked in an orange emission color until a normal state in which no abnormality is detected is obtained.

  Examples of use are given below.

Light. For this reason, the user looks at the light emitting unit 41 that is lit in white, and the operation units 8a to 8c provided with the light emitting unit 41 operate the stove burners 3a to 3c in which the heated objects are arranged. It can be easily recognized that they are 8a to 8c.

  Further, heating by the burner burners 3a to 3c can be set by the setting input panel 34 without detecting the abnormal state of the burners by the abnormality detecting means in a state where the object to be heated is arranged on the burner burners 3a to 3c. On the basis of the normal completion, the light emitting units 41 of the operation units 8a to 8c corresponding to the stove burners 3a to 3c blink in white light emission color. For this reason, the user can easily see that the heating by the burner burners 3a to 3c corresponding to the operation units 8a to 8c provided with the light emitting unit 41 has been normally finished by looking at the light emitting unit 41 flashing white. Can be recognized.

  In addition, when an abnormality is detected by the abnormality detecting means in a state where the object to be heated is placed on the stove burners 3a to 3c and heating by the stove burners 3a to 3c is finished, the stove is concerned. The light emitting units 41 of the operation units 8a to 8c corresponding to the burners 3a to 3c blink in an orange emission color. For this reason, the user can easily see that the heating by the burner burners 3a to 3c corresponding to the operation units 8a to 8c provided with the light emitting unit 41 is terminated due to an abnormality by looking at the light emitting unit 41 blinking in orange. Can be recognized.

  In the present embodiment, the first emission color of the light emitting unit 41 provided in each operation unit 8a to 8c is white and the second emission color is orange, but the second emission color is the first. The first emission color and the second emission color may be other emission colors as long as the emission color is recognized as having a higher alarm level than the emission color.

Moreover, when the to-be-heated material is arrange | positioned on the stove burners 3a-3c, the lighting of the light emission part 41 is in the state where the to-be-heated material is not heated by the said stove burners 3a-3c,
Although the light emission color is the same as the light emission color when heating by the stove burners 3a to 3c is normally completed, a different light emission color may be used.

  Further, when the object to be heated is arranged on the stove burners 3a to 3c, the light emitting unit 41 is turned on when the object to be heated is heated by the stove burners 3a to 3c. Thus, although the light emission color is the same as the light emission color when the heating of the gas stove burners 3a to 3c is finished by detecting the abnormality of the gas burner 3a to 3c, a different light emission color may be used.

  Furthermore, although the stove of this embodiment is the drop-in type gas stove 1 incorporated in the kitchen cabinet, it may be the gas stove 1 installed on the stove stand, and is an IH cooker. It may be.
