Detect boiling of objects. Moreover, the 2nd boiling detection part 52 detects the boiling of a to-be-cooked object based on the temperature (temperature of the bottom part of a cooking container) detected by the temperature sensor 8 (8L, 8R).

  When the first boiling detector 51 or the second boiling detector 52 detects the boiling of the cooking object, the boiling countermeasure unit 53 reduces the heating power of the cooker 4 that is heating the cooking object. And handle the boiling to extinguish.

  The sound notification unit 55 sounds the buzzer 46 to notify the abnormality when detecting the abnormality of the cooking device 1 (the failure of the temperature sensor 8, the misfire of the cooker 4 due to the spilled food from the cooking container, etc.). To do. Moreover, the sound alerting | reporting part 55 outputs audio | voice guidance from the speaker which is not shown in figure, when the boiling of the to-be-cooked object is detected.

In addition, the boiling detection prohibiting unit 54 is in a state where the buzzer 46 is sounded by the sound notification unit 55 and the voice guidance is being output when the water boiling operation is being executed by any of the burners 4. The detection of boiling by the first boiling detector 51 is prohibited.

  Next, according to the flowcharts shown in FIG. 4 to FIG. In addition, the process of the water heater operation of the left stove 4L is performed similarly.

  The user puts water (to-be-cooked object) in a cooking container (for example, a whistling kettle), places it on the virtues 7 of the right stove 4R, and operates the water heater switch 16 of the operation unit 14R for the right stove 4R. Thus, the start of the water heater operation of the right stove 4R is instructed.

  When the control unit 50 recognizes that the water heater switch 16 of the operation unit 14R for the right stove 4R has been operated, the control unit 50 starts the process according to the flowcharts shown in FIGS. 4 to 5, and in STEP1, the ignition process of the right stove 4R I do. Specifically, the control unit 50 opens the electromagnetic valve 34R and the flow rate control valve 35R in a state where a spark discharge is generated in the ignition electrode 40R, and the ignition is detected by a flame sensor (frame rod, thermocouple, etc.) not shown. When this is done, the spark discharge of the ignition electrode 40R is stopped.

  In subsequent STEP2, the control unit 50 sets the heating power (heating amount) of the right stove 4R to “large” (for example, maximum heating power) by the flow rate adjusting valve 35R. Subsequent STEP 3 to STEP 11 in FIG. 5 are processes by the second boiling detector 52. The second boiling detector 52 detects the boiling of the object to be cooked by the method described in the above-mentioned Japanese Patent Application Laid-Open No. 2008-232560.

  The second boiling detector 52 waits until the detected temperature T of the temperature sensor 8R (the temperature of the bottom of the cooking vessel W) reaches 70 ° C. or higher in STEP 3 and proceeds to STEP 4. In STEP 4, the second boiling detector 52 starts measuring the rising slope ΔT of the temperature T detected by the temperature sensor 8R.

  Here, the second boiling detector 52 starts from 70 ° C. and starts at each gradient temperature i, i + 1, i + 2, i + 3 to the next gradient temperature i + 1, i + 2, i + 3, i + 4. Times Cn1, Cn2, Cn3, Cn4 required for the temperature T detected by the temperature sensor 8R to rise are measured.

  Then, when the detected temperature T reaches i + 4, the second boiling detector 52 calculates the rising slope ΔT of the detected temperature T from the measured values of Cn1 to Cn4 at that time by the following equation (1). . The rising slope ΔT represents the average time required for the detected temperature T to rise by 10 ° C.

ΔT = Cn1 + Cn2 + Cn3 + Cn4-Max-Min (1)
However, Max: the maximum value of Cn1 to Cn4, Min: the minimum value of Cn1 to Cn4.

  Thereafter, the second boiling detector 52 newly calculates and updates the rising gradient ΔT every time the detected temperature T increases by 5 ° C.

  In the next STEP5, when the detected temperature T of the temperature sensor 8R becomes 90 ° C. (corresponding to the predetermined temperature of the present invention) or more, the process proceeds to STEP6, and the second boiling detector 52 measures the rising slope ΔT. finish. Then, the second boiling detector 52 determines the boiling predicted value J in STEP 7 according to the rising slope ΔT.

  Here, the predicted value J at the time of boiling is a reference time for determining that the object to be cooked is boiling from the time required for the temperature T detected by the temperature sensor 8R to rise by 5 ° C. As described in JP 2008-232560 A, the second boiling detector 52 sets the boiling predicted value J to a longer time as the rising gradient ΔT is longer.

  In subsequent STEP8 and STEP9, the second boiling detector 52 determines the waiting time timer Tm1 for measuring the waiting time until the calculation of the degree of stability of the temperature detected by the temperature sensor 8R and the rising slope ΔT. A time limit timer Tm2 for measuring the time limit from the time point until the detection of boiling is started.

  In the next STEP 10, when the waiting time timer Tm 1 has timed up, the process proceeds to STEP 11 in FIG. 5, and the second boiling detector 52 determines that the degree of stability of the detected temperature T of the temperature sensor 8 R is equal to or higher than the boiling predicted value J. Determine whether or not.

  Specifically, the second boiling detection unit 52 performs one second from when the temperature T detected by the temperature sensor 8R reaches 90 ° C. (counting start temperature) until the temperature T detected by the temperature sensor 8R increases by 5 ° C. Every time it elapses, the counter is counted up. Further, when the detected temperature T of the temperature sensor 8R becomes a temperature different from the count start temperature, the second boiling detecting unit 52 counts up another counter every second until the temperature rises by 5 ° C. from this temperature. I do.

  In the present embodiment, the second boiling detector 52 uses five counters X1, X2, X3, X4, and X5, and count start temperatures Tx1, Tx2, Tx3, Tx4, and Tx5 of these five counters. Data in memory. And the 2nd boiling detection part 52 performs simultaneously the count process of five counters X1-X5 from which start time differs.

  The second boiling detection unit 52 counts when one of the counters Xn (n: 1 to 5) has finished counting (when the detected temperature T rises by 5 ° C. from the count start temperature Txn) or when the detected temperature T is counted. When the temperature becomes lower than the start temperature Txn, the count value of the counter Xn and the count start temperature Txn are cleared.

  Then, when the temperature detected by the temperature sensor 8R changes to a temperature different from any of the other count start temperatures, the second boiling detector 52 counts the counter Xn with the temperature as the count start temperature Txn. To start.

  The second boiling detection unit 52, in STEP11, when the count value (temperature stability degree) of any of the five counters X1 to X5 is equal to or greater than the boiling predicted value J (in the cooking container). (When it is estimated that the food to be cooked is in a boiling state), proceed to STEP12.

  On the other hand, if the count values of the five counters X1 to X5 are all smaller than the boiling predicted value J in STEP11, the process branches to STEP20. STEP 20 is a process performed by the first boiling detector 51.

  The first boiling detection unit 51 estimates that the cooking object in the cooking vessel is in a boiling state from the detection sound of the sound sensor 45 when the sound sensor 45 continuously detects a sound of a predetermined level or higher. ), Proceed to STEP12. Here, as a sound (boiling estimation sound) that is estimated to be boiled to-be-cooked, whistling kettle is used to boil hot water, whistling kettle sound emitted from whistling kettle, hot water in lidded pot Sounds generated when the lid is moved up and down by water vapor when boiled, sounds where hot water boils, and the like are assumed.

  In addition, by performing the process (extraction by a band pass filter etc.) which extracts a boiling estimated sound from the sound detected by the sound sensor 45 according to the characteristics (frequency, generation period, etc.) of the boiling estimated sound, You may make it prevent that the boiling of a to-be-cooked object is misdetected by sounds other than a boiling estimated sound.

  In addition, the boiling detection prohibition unit 54 prevents the first boiling detection unit 51 from erroneously detecting that the cooking object is in a boiling state based on a sound other than the sound generated from the cooking container or the cooking object. Process to do.

  First, when the boiling operation of the right stove 4R is being performed, the boiling detection prohibiting unit 54 monitors the presence or absence of ignition processing of the other stove 4B, 4L and the grill 5, and the other stove 4B, 4L and the grill 5 While any of these ignition processes is being performed, the boiling detection process by the first boiling detection unit 51 in STEP 20 is prohibited. And thereby, the spark discharge sound of the ignition electrode produced at the time of execution of the ignition process is detected by the sound sensor 45, and the first boiling detector 51 erroneously detects the boiling of the object to be cooked based on the detected sound. Is preventing.

  Further, the boiling detection prohibition unit 54 monitors whether or not the buzzer 46 is sounded by the sound notification unit 55 when the water heating operation of the right stove 4R is being performed, and while the buzzer 46 is sounding, in STEP20 The boiling detection process by the first boiling detection unit 51 is prohibited. Thus, the output sound of the buzzer 46 is detected by the sound sensor 45, and based on this detected sound, the first boiling detector 51 is prevented from erroneously detecting the boiling of the object to be cooked.

  STEP 12 to STEP 16 are processes by the boiling countermeasure unit 53. In step 12, the boiling countermeasure unit 53 sets the heating power (heating amount) of the right stove 4R to a low heat (for example, the minimum heating power), and sounds the buzzer 46 in the subsequent STEP 13 to notify the user that the hot water has boiled. To do.

  The next STEP 14 waits for 5 minutes to proceed to STEP 15, and the boiling countermeasure 53 closes the flow control valve 35R and the electromagnetic valve 34R and extinguishes the right stove 4R. Moreover, the boiling countermeasure part 53 alert | reports to a user that the boiling water operation was completed by sounding the buzzer 46 by continuing STEP16. Then, the process proceeds to STEP 17, and the control unit 50 ends the water heating operation process.

  In the present embodiment, the boiling detection prohibiting unit 54 (1) ignites other burners when cooking by a burner that is a target of boiling detection by the first boiling detection unit 51 is being performed. While the process is performed and a spark sound is output from the ignition electrode, and (2) while the sound is output by the sound notification unit 55, the first boiling detection unit 51 prohibits boiling detection. The effect of the present invention can also be obtained when prohibiting only one of (1) and (2). In addition, when the cooking device includes an element that generates sound in addition to the ignition electrode and the sound notification unit 55, the first boiling detection unit while this element outputs sound also for this element. The boiling detection by 51 may be prohibited.

  Moreover, in this embodiment, the boiling detection by the 1st boiling detection part 51 and the boiling detection by the 2nd boiling detection part 52 were performed, However, When only the boiling detection by the 1st boiling detection part 51 is performed Also, the effects of the present invention can be obtained.

  In the present embodiment, the boiling detection is performed by the first boiling detector 51 after the detected temperature of the cooking container reaches 90 ° C. or higher. However, the first boiling is not performed without providing such temperature limitation. You may make it perform the boiling detection by the detection part 51. FIG.

  Moreover, in this embodiment, although the gas stove was shown as a heating cooking apparatus of this invention, this invention is applicable also to other types of heating cooking apparatuses, such as an electric stove.

  Further, the process of prohibiting the detection of boiling by the first boiling detection unit 51 by the boiling detection prohibiting unit 54 is performed only when an abnormality notification is given by the buzzer 46, and other sounds (voice guidance, etc.) With respect to, by prohibiting the output while the boiling detection by the first boiling detector 51 is being performed, the first boiling detector 51 is prevented from erroneously detecting boiling by sound other than the boiling sound.
