I have.

The configuration related to gas supply to the stove burner and the grill burner is as follows.
A source gas solenoid valve 12 is provided in a source gas supply path (main gas pipe) 11. From the source gas supply path 11, a branch path 13 a for a standard burner, a branch path 13 b for a high thermal power burner, a branch path 13 c for a small burner, It is branched to a grill burner branch path 13d.

  Each of these branch paths has a flow control valve (a gas amount control valve driven by a stepping motor) 3 for adjusting a gas amount to adjust a heating amount of each burner, and a position for detecting its opening position. A sensor 19 is provided.

  When the heating condition adjusting unit 21 (21a, 21b, 21c) is protruded from the front surface of the appliance body 10 in a burning state and the heating condition adjusting unit 21 (21a, 21b, 21c) is pinched and rotated by a finger, this is a rotary encoder ( (Not shown) and input to the control unit.

The control unit controls the gas amount of the stove unit by driving the stepping motor according to a signal from the rotary encoder.
In addition, when performing the temperature control in the rice cooking mode, the water boiler mode, or the like, the stove unit is controlled to a value suitable for control regardless of the rotational operation position of the heating state adjusting unit 21 (21a, 21b, 21c). The gas volume is controlled.

  The flow control valve 3 is also configured to be switchable to a shielded state where the adjusted flow rate is set to zero.

In addition, in the gas stove of this embodiment, the gas amount control valve driven by the stepping motor is provided as described above, but when the gas amount is controlled mechanically, a mechanical manual gas amount control valve is used. By equipping a gas solenoid valve for limiting the gas amount in series, it is possible to execute each mode process described later.
However, when a mechanical manual gas amount control valve is used, a reliable control is performed by the user adjusting the manual control valve to the maximum gas amount position before executing each mode.

  When a gas amount control valve driven by a stepping motor is provided, the control unit controls the gas amount to an arbitrary value in a range from the minimum to the maximum regardless of the gas amount adjustment position when each mode is executed. Since there is a possibility that there is no need for the user to adjust the maximum gas position before executing each mode.

  In this gas stove, timer cooking can be executed. By operating the timer setting unit 41 of the additional function operation / display unit 32 for the standard burner 1a shown in FIG. When heating by 1a is started, timer cooking by the standard burner 1a is executed.

  During the execution of the timer cooking, the remaining time for timer cooking is reduced and updated as time elapses, and is displayed on the timer time display section 42. The timer cooking function is provided by a so-called subtraction timer, in which the heating by the standard burner 1a is stopped when the updated remaining time for timer cooking becomes zero and the timer cooking is terminated.

  The heating cooker according to this embodiment has a characteristic configuration of the present invention as described below.

  That is, in the heating cooker according to the present embodiment, the temperature of the cooking container detected by the temperature detecting means (pan bottom temperature sensor) 9 is equal to or higher than the first set temperature which is a temperature suitable for charging food. When the temperature of the cooking vessel detected by the temperature detecting means (pan bottom temperature sensor) 9 is set higher than the first set temperature, the temperature is set too high to feed the food. When the temperature is equal to or higher than the second set temperature, the notification is performed in the second mode.

  More specifically, when cooking a stir-fry, for example, using this heating cooker, when the standard burner operating section 21a is operated to start heating with the standard burner (heating section) 1a, the heating power is in a heating state. An arbitrary heating power adjusted by the adjusting unit 21 is obtained.

  Then, when the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 reaches 180 ° C., which is the first set temperature, as shown in FIG. Will be notified. Note that the instruction manual for the cooking device states that the notification in the first mode is a notification to inform that the temperature has reached a temperature suitable for charging the food, and the user is notified in advance. Be prepared to be.

  Examples of the notification of the first mode include a mode in which an LED provided on the combustion indicator lamp 23 near the standard burner operation section 21a is blinked and a beep is generated in a one-second cycle. There are no special restrictions.

  Thereafter, heating is further continued without the addition of foodstuffs, and the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 becomes equal to or higher than the second set temperature of 220 ° C. as shown in FIG. When reached, a second mode alerts that the temperature is too high for the ingredients to be charged. Note that the instruction manual states that the notification in the second mode is a notification to notify that the temperature is higher than the temperature suitable for feeding the ingredients, and is recognized by the user in advance. Be prepared to be.

  In addition, as the notification of the second mode, a mode in which the LED provided on the combustion display lamp 23 near the standard burner operation unit 21a is turned off, and a beep is generated in a 0.5-second cycle, or the like is exemplified. There are no particular restrictions on the mode.

  Further, when the temperature control function of the standard burner 1a such as fried food is executed, when the standard burner operation unit 21a is operated to start heating by the standard burner 1a, for example, the set temperature set to 160 ° C. is set to the first temperature. The heating amount of the standard burner 1a is adjusted by the control unit so that the heating amount of the standard burner 1a increases or decreases according to the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 as the set temperature of.

  Then, when the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 reaches 160 ° C., which is the first set temperature, it is notified in a first mode that the temperature is suitable for feeding food.

  Thereafter, the standard burner is controlled by the control unit so that the heating amount of the standard burner 1a increases or decreases in accordance with the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 with the first set temperature of 160 ° C. as a target value. The heating amount adjustment of 1a is executed. At this time, even if the heating amount of the standard burner 1a is maintained at the minimum heating power, the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 may exceed the second set temperature of 220 ° C. For example, when the cooking container is small and the amount of oil is too small (for example, 20 ml or less), the oil temperature may exceed 220 ° C. even if the heating power is switched to the minimum heating power. Then, in that case, it is notified in a second mode that the temperature is high to feed the food.

  Regardless of the cooking mode such as fry cooking and fry cooking, when the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 further rises above 220 ° C. and reaches a predetermined temperature, heating is performed. Since the safety mechanism provided in the cooker is operated to stop the heating, the safety is not impaired.

  In addition, regardless of the cooking mode such as stir-fry cooking and fried food cooking, when the notification in the first mode or the second mode is performed, the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 When detecting a temperature decrease of a predetermined width (for example, 10 ° C.), the notification in the first mode is stopped when the notification is performed in the first mode, and the notification is performed in the second mode. Is performed in the second mode.

  This is because when the temperature detected by the temperature detecting means (pan bottom temperature sensor) 9 detects a decrease in the temperature within a predetermined width (for example, 10 ° C.), it can be considered that the food has been introduced, so It is meaningless to continue the notification in the first mode or the second mode (that is, it is not necessary to prompt the user to input food or to notify that the food is not suitable for input).

  According to the heating cooker (gas stove with grill) according to this embodiment configured as described above, the temperature (the first set temperature) suitable for charging the food has been reached, and the charging of the food has not been completed. Since it is possible to surely recognize that the temperature has become too high (the second set temperature), the user can surely know the time of feeding the food.

[Modification 1]
In the above-described embodiment, the notification of the first mode is a notification of a mode in which an LED provided in the heating state adjusting unit is blinked and a beep is generated in a one-second cycle, and the notification of the second mode is While the LED provided in the heating state adjusting unit is turned off and the notification of the beeping sound in a 0.5-second cycle is described as an example, the sound in the notification of the above-described first embodiment is described. The notification is, for example, a notification (continuous notification) in which a specific sound notification of “pip-pip” is continued in a one-second cycle, while the notification of the second mode is the same as the notification of the specific sound notification of the first mode. It may be set to stop (that is, stop of the notification that has been continuously performed).

  Further, in the above embodiment, the blinking of the LED and the sound notification are combined. However, the notification is performed only by the blinking of the LED, and the blinking mode is made different between the report of the first mode and the report of the second mode. It is also possible to notify only by sound notification, and to make the form as in the case of the above-described embodiment or the above-described modification.

[Modification 2]
Further, in the above embodiment, the first set temperature is set to 160 ° C. or 180 ° C., and the second set temperature is set to 220 ° C., but the first set temperature and the second set temperature can be changed as needed. It is also possible.

[Modification 3]
Further, in the above-described embodiment, the notification of the first mode and the notification of the second mode are performed by blinking or extinguishing the LED provided in the heating state adjusting unit, and changing the cycle of the sound notification (one second cycle and 0.5 (Change of the second cycle) has been described, but the notification mode is not particularly limited. For example, the heating power indicator lamp on the display unit provided on the top plate blinks, the emission color of the LED is changed, and the sound source is changed. It is also possible to use a buzzer sound and change its length and cycle. Also, the sound notification can be described as a sound.
