The thermal power control lever 121a is a lever movable from 'strong' to 'weak' as shown in FIG. 3, whereby the thermal power of the standard burner 103 is adjusted. In addition, since the heating amount at the time of cooking is about 1300 kW / h, the thick line 123 is displayed in the site | part corresponding to this cooking power, and is labeled "cooking".

In addition, a battery replacement lamp 125 and a grill ignition confirmation lamp 127 are also provided on the front surface of the gas stove 101 having a cooking function.

4 is a schematic block diagram showing an internal configuration of a gas furnace having a cooking function of FIG.

Gas is supplied to each of the standard burner 103, the 'strong' thermal burner 105, and the grill burner 131 through the gas pipe 129. The gas pipe 129 is branched for the standard burner 103, the 'strong' fire burner 105, and the grill burner 131, and safety valves 133a, 133b, and 133c are provided for each branch. The thermal control levers 121a, 121b and 121c are respectively located between the safety valve 133a and the standard burner 103, between the safety valve 133b and the 'strong' thermal burner 105, the safety valve 133c and the grille, respectively. It is provided between the burner 131. These thermal control levers 121a, 121b, 121c are controlled by the cooker as described above, and have no relationship with the control unit 143 described later. However, a micro switch 134 is provided for detecting that the thermal power is set to the cooking power, and the micro switch 134 outputs the detection signal to the control unit 143 described later. Further, the gas pipe 129 is further branched between the safety valve 133a and the thermal power control lever 121a, and an electromagnetic valve 135 is provided for the branch on one side. When the solenoid valve 135 is closed, it becomes the thermal power of about 350 kW / h which is a weak thermal power, and when the solenoid valve 135 is opened, it becomes the thermal power adjusted by the thermal control lever 121a.

The standard burner 103, 'strong' thermal burner 105, and grill burner 131 are ignited by sparking the electrodes 139a, 139b, 139c, and 139d connected to the igniter 137, respectively. Whether the ignition is ignited or not, the ignition checker 141a corresponding to the standard burner 103, the ignition checker 141b corresponding to the 'strong' thermal burner 105, and the ignition checker 141c corresponding to the grill burner 131. ) Is detected. The ignition checkers 141a, 141b, and 141c are, for example, thermocouples.

The safety valves 133a, 133b, and 133c, the solenoid valve 135, the temperature sensor 107, the ignition checkers 141a, 141b, and 141c, and the igniter 137 are connected to the control unit 143. 111, the ignition operation buttons 119a, 119b, and 119c are controlled by signals from the operation board 145 to be operated. The control unit 143 also stores data for cooking, and the safety valve 133a and the like are also controlled by this data.

In addition, an alarm unit 147 is connected to the control unit 143. The alarm unit 147 includes a buzzer 149 and lamps 117a and 117b. The alarm unit 147 alarms when the cooking mode button 117 is in a non-selected state in which the thermal power control lever 121a is adjusted to set the thermal power to the cooking power.

FIG. 5 is a block diagram showing the configuration of the first embodiment in which the configuration required in the control section in FIG. 4 is made clear.

In FIG. 5, the control unit 143 includes a mode selection state determination unit 151. Other related configurations shown below will also be described. The standard burner 103 is an example of heating means for heating the heated object with a manually set fire power. The thermal power control lever 121a is for manually setting the thermal power of the standard burner 103. The cooking mode button 117 is an example of cooking mode selection means for setting to the cooking mode. The control unit 143 performs cooking cooking when the manually set fire power of the standard burner 103 is a preset cooking power and the cooking mode button 117 is in an ON state (a cooking mode is selected). To control the thermal power, and outputs a control signal to the solenoid valve 135 to constitute a thermal control means together with the solenoid valve 135. The micro switch 134 is an example of the cooking power detecting means, and by detecting that the thermal power control lever 121a is set at the position of the thick line 123 marked as 'cooking', the thermal power of the standard burner 103 is cooking power. Detect. In response to the detection of the microswitch 134, the mode selection state determination unit 151 turns the state of the cooking mode button 117 into the ON state (the cooking mode is selected) or the OFF state (the non-selecting state in which the cooking mode is not selected). Is an example of the selection state discrimination means for discriminating any one of The alarm unit 147 is an example of alarm means for informing that the mode selection state determination unit 151 determines that the mode is not selected.

6 is a flowchart for explaining the operation of the configuration shown in FIG.

In FIG. 6, it is determined in step 201 whether the thermal power is set to the cooking power after ignition. This determination is made by whether or not the microswitch 134 is detected. Unless the microswitch 134 is detected, heating is performed as a normal furnace as shown in step 202. On the other hand, when the microswitch 134 detects, it progresses to step 203 and determines whether the cooking mode button is ON. This determination is made by the mode selection state determination unit 151. In the ON state, the cooking heating is executed as shown in step 204. In the OFF state, an alarm sounds as shown in step 205. The alarm is performed by the alarm unit 147. Specifically, the lamp 117a flashes and the buzzer 149 sounds an alarm. As a result, if the cook forgets to press the cooking mode button 117, the cooking mode button 117 is pressed again to discriminate as shown in step 206, and the cooking proceeds to step 204 to perform cooking. . If the cooking mode button 117 is not pressed in spite of the warning, that is, if the cooker desires heating as the normal furnace, the process proceeds to step 202 and heating is performed as the normal furnace.

In this way, the alarm for preventing forgetting of the pressing operation of the cooking mode button 117 sounds, and the cook can recognize that the pressing operation of the cooking mode button is forgotten by this alarm. As a result, when the cook forgets to press the cooking mode button, the cooker can press the cooking mode button to enter the mode selection state, and the appropriate cooking heating set in the cooking mode is executed by the cooking power to delete the delicious rice.

The processing proceeding from step 203 to step 204 corresponds to the case where the microswitch 134 detects after the cooking mode button 117 is pressed and turned ON.

In addition, the lamps 117a and 117b may be turned on to alarm without blinking, or may be alarmed by using a separate lamp. In addition, either an alarm using a lamp or an alarm using a buzzer may be used.

Fig. 7 is a block diagram showing the configuration of the second embodiment.

The structure different from FIG. 5 is demonstrated. The heating state determination unit 301 is further provided. The heating state determination unit 301 is an example of the temperature measurement means as an example of the heating state discriminating means for determining whether the heating state of the standard burner 103 is included in the cooking heating state in response to the detection of the micro switch 134. And a discriminating unit 303 as an example of the discriminating means into which the temperature sensor 107 as an input and the output of the temperature sensor 107 are input. The detection signal of the micro switch 134 is input to the determination unit 303 of the heating state determination unit 301, and the determination result of the determination unit 303 is input to the mode selection state determination unit 151.

8 is a flowchart for explaining the operation of the configuration shown in FIG.

Hereinafter, a part different from the flowchart of FIG. 6 is demonstrated. Steps 401 and 402 correspond to steps 201 and 202, and step 403 is added after step 401. Step 403 is a step for determining whether or not the sensor temperature is 100 ° C. or less. If it is 100 ° C. or less, the process proceeds to step 404, and if larger than 100 ° C., proceeds to step 402. This processing is necessary because an alarm sounds as it is in the processing of FIG. 6 when the thermal power is set to the cooking power in a state where heating is performed as a normal furnace. This alarm is an unnecessary false alarm, and in order to prevent such an alarm, when the sensor temperature is higher than 100 ° C, it is determined that the thermal power is accidentally set to the cooking power in the normal use furnace, and the heating is performed as a normal furnace. Continue. On the other hand, when it is 100 degrees C or less, since it may be cooking heating, it progresses to step 404 corresponding to step 203. Processing below step 404 is the same as step 204, 205, 206 of FIG. 6, and step 405, 406, 407 corresponds to step 204, 205, 206, respectively.

9 is a block diagram showing the configuration of the third embodiment, and FIG. 10 is a flowchart for explaining the above operation.

Hereinafter, the parts different from those of Figs. 7 and 8 will be described in particular. The heating state determination unit 501 is provided in place of the heating state determination unit 301, and the heating state determination unit 501 serves as an example of the timer 503 as an example of the ignition checker 141a and the measurement means and as an example of the determination means. The determination unit 505 is included. As for the operation, all processes are the same except that step 603 is set instead of step 403, and each of steps 601, 602, 604, 605, 606, and 607 corresponds to steps 401, 402, 404, 405, 406, and 407. . Step 603 is a process of determining whether or not the elapsed time after ignition is within 180 seconds. Also by this process, it is possible to determine whether or not to set cooking power by accident during heating as a normal furnace. It is thought that this is within 180 seconds if the thermal power setting for cooking heating is performed immediately after the ignition, but when the cooking power is accidentally set in the heating state as a normal furnace, since the time elapses considerably from the ignition. Because it is difficult to do. In this way, it is possible to discriminate whether or not it is set to the cooking power at the time of heating as a normal furnace, and as a result, unnecessary alarm can be prevented.

Fig. 11 is a block diagram showing the configuration of the fourth embodiment.

In this embodiment, the cooking mode button 117 and the alarm unit 147 are deleted. Therefore, when the detection signal from the micro switch 134 is input, the control part 701 outputs a control signal to the solenoid valve 135, and makes automatic control. As a result, the cooking mode button 117 becomes unnecessary, so that the problem of improper cooking heating due to forgetting of the pressing operation of the cooking mode button does not occur.

However, if automatic cooking is performed so that cooking heating is always performed every time the cooking heating power is set, the cooking state heating unit 703 is set because cooking cooking is performed even when the cooking heating power is accidentally set during heating as a normal stove. . The heating state determination unit 703 includes a temperature sensor 107 and a determination unit 705, the determination unit 705 receiving the detection signal from the micro switch 134 is the measured temperature measured by the temperature sensor 107 Based on this, it is determined whether the heating state is included in the cooking heating state.

12 is a flowchart for explaining the operation of the configuration shown in FIG.

In FIG. 12, steps 801, 802, and 803 correspond to steps 401, 402, and 403 of FIG. 8. Then, steps 404, 406, and 407 are deleted, and if the sensor temperature is 100 ° C or lower in step 803, the process proceeds to step 804 for step 405. This is because since the automatic force control for cooking heating is started, it is determined whether the cooking mode button is ON or not, and processing based on this determination result is unnecessary. In step 803, it is determined whether or not the sensor temperature is 100 ° C. or lower. As a result, when the temperature is higher than 100 ° C., it can be determined that the cooking power is accidentally set at the time of heating as a normal furnace. In order to prevent starting of the thermal control, the control unit 701 stops the output of the control signal to the solenoid valve 135. Therefore, when it is set as cooking power, thermal power control such as cooking heating is automatically executed as a rule, but when it is set as cooking power by accident during use as a normal furnace, heating as a normal furnace is continued.

FIG. 13 is a block diagram showing the configuration of the fifth embodiment, and FIG. 14 is a flowchart for explaining its operation.

The parts different from FIG. 11 and FIG. 12 are demonstrated. A heating state determination unit 901 is set instead of the heating state determination unit 703 shown in FIG. 11, and the heating state determination unit 901 uses the ignition checker 141a and the timer 503 in addition to the temperature sensor 107. Include. The discriminating unit 903 set in place of the discriminating unit 705 has a heating state based on both the measured temperature measured by the temperature sensor 107 and the elapsed time after ignition measured by the timer 503. Determine if it is included or not.

The operation is followed by step 954 for determining whether the elapsed time after ignition is within 180 seconds or not after step 953 for determining whether the sensor temperature is 100 ° C. or lower, as shown in FIG. 14, and through the processing of steps 953 and 954. Proceeding to step 955, cooking cooking is executed. Here, steps 951, 952, 953, and 955 correspond to steps 801, 802, 803, and 804, respectively.

In the second embodiment shown in Fig. 7, the heating state is determined based on the measured temperature measured by the temperature sensor. In the third embodiment shown in Fig. 9, the heating state is determined based on the measurement time measured by the timer. However, the heating state may be determined using both the measurement temperature of the temperature sensor and the measurement time of the timer.

Incidentally, the furnace having a cooking function is not limited to a gas furnace, but may be an electric furnace.

In addition, numerical conditions etc. can be changed according to various factors, and are not limited to what was demonstrated in embodiment.

The invention of claim 1 detects that the manually set fire power is cooking power, determines the selection state of the cooking mode in response to the detection, and prevents forgetting of the selection setting to the selection state in the non-selection state. In order to alert the cooker, it is possible to prevent the cooker from heating (normal heating) as it is without the cooking mode being left unselected.

Unnecessary false alarms can be prevented.

In the invention of claim 5, when the manually set thermal power is cooking power, the thermal power control is started so as to cook the cooking heat. Therefore, selection of the cooking mode is unnecessary, and therefore, even though the cooker desires cooking, It is possible to prevent heating as a normal furnace caused by forgetting the selection setting.

In the invention of claim 6, even when the thermal power is set to the cooking power in the case of using as a normal furnace, it is determined whether the heating state is included in the cooking heating state, and in the case of determining that it is not included, the heating power of cooking heating Since the start of control is prevented, it is possible to prevent the start of thermal control of wrong cooking heating.
