It is characterized by that.

  In the cooking device according to the present invention, when performing the boiled food operation, the cooking control unit heats the cooking container filled with water by the boiling process, and detects boiling of water in the cooking container by the boiling detection means. To do. Next, when the user puts an object to be cooked into the cooking container after the water in the cooking container has boiled, the temperature of the water in the cooking container is lowered, and is generated along with the generation of water vapor at the time of boiling. The boiling sound disappears or weakens temporarily. Therefore, the cooking control unit recognizes the input of the food to be cooked into the cooking container according to the change of the sound detected by the sound detection means in the food cooking input recognition step after the boiling of water is detected. . And after input of the to-be-cooked object in a cooking container is recognized, an object control is performed by the cooking process which heats the cooking object in a cooking container, adjusting the heating power of a heating part with a cooking process.

  Thus, in the cooking device of the present invention, when the user puts the food to be cooked into the cooking container after the water in the cooking container has boiled, the change in the sound detected by the sound detection means is determined. Input of the food to be cooked into the cooking container is recognized, and the boiled food control is executed. Thereby, a user can perform boiled material control by a cooking control part, without performing operation which instruct | indicates the completion of injection | pouring of the to-be-cooked object in a cooking container to a cooking control part.

It is preferable to adjust the heating power of the heating unit so that the water in the cooking container is kept boiling until it is recognized that an object has been charged.

  According to this configuration, after the cooking control unit detects boiling of the water in the cooking container in the boiling process, the cooking control unit inputs the cooking object into the cooking container in the cooking object input recognition process. Until the recognition, the boiling state of the water in the cooking container can be maintained, and the state where the volume of the sound generated in the vicinity of the heating unit is high can be maintained. Thereby, it is possible to easily determine a change in sound detected by the sound detection means.

  In addition, the cooking device of the present invention is configured to determine a change in sound detected by the sound detection unit in the to-be-cooked object insertion recognition step. As a configuration for performing this determination, for example, the sound Recording means for recording the sound detected by the detection means is further provided, and the recording means is detected by the sound detection means when the boiling detection means detects boiling of water in the cooking container in the boiling step. The to-be-cooked input recognition step determines that the sound detected by the sound detecting means has changed from the sound recorded by the recording means, and It is good also as what recognizes input of a cooking thing.

  According to this configuration, it is possible to easily and reliably determine a change in sound before and after the cooking object is charged in the cooking object charging recognition step.

The cooking mode is selected by operating the water heater switch 60 of the operation unit 14L for the stove 4L.

[1. Select cooking mode]
FIG. 3 is a process for selecting the cooking mode of the left stove 4L. In STEP1, when the water heater switch 60 is turned on (the user operates the water heater switch 60), the process proceeds to STEP2, and the cooking controller 51 Then, the cooking mode of the left stove 4L is set to the “water heater mode”, and the process proceeds to STEP3.

  In STEP 3, the cooking control unit 51 determines whether or not the water heater switch 60 is turned on. Then, when the water heater switch 60 is turned on, the process proceeds to STEP 4, and the cooking control unit 51 sets the cooking mode of the left stove 4L to “boiled food mode” and proceeds to STEP 5.

  On the other hand, when the water heater switch 60 is not turned on in STEP 3, the cooking control unit 51 determines whether or not there is a heating cooking start operation in the “water heater mode”.

  In STEP 5, the cooking control unit 51 determines whether or not the water heater switch 60 is turned on. When the water heater switch 60 is turned on, the process proceeds to STEP 6, and the cooking control unit 51 sets the cooking mode of the left stove 4L to “mode with noodle bowl” and proceeds to STEP 7.

  On the other hand, when the water heater switch 60 is not turned on in STEP 5, the cooking control unit 51 determines whether or not the heating cooking start operation in the “boiled food mode” is performed.

  In STEP 7, the cooking control unit 51 determines whether or not the water heater switch 60 is turned on. When the water heater switch 60 is turned on, the process proceeds to STEP8, and the cooking control unit 51 sets the cooking mode of the left stove 4L to "large mode with noodle bowl" and proceeds to STEP9.

  On the other hand, when the water heater switch 60 is not turned ON in STEP 7, the process branches to STEP 20 in FIG. 4, and the cooking control unit 51 determines whether or not the operation of starting cooking by the “noodle bowl mode” is performed.

  In STEP 9, the cooking control unit 51 determines whether or not the water heater switch 60 is turned on. Then, when the water heater switch 60 is turned on, the process proceeds to STEP 10, and the cooking control unit 51 cancels the setting of the cooking mode to enter the cooking mode setting standby state, and returns to STEP 1.

  On the other hand, when the water heater switch 60 is not turned on in STEP 9, the cooking control unit 51 determines whether or not a heating cooking start operation is performed in the “noodle bowl large mode”.

[2. Noodle bowl mode]
STEP 20 to STEP 24 and STEP 30 to STEP 31 in FIG. 4 are cooking operation processes by the “noodle bowl mode”.

  The cooking control unit 51 displays the initial time (for example, 5 minutes) of the cooking timer on the timer display unit 81 of the display panel 13 in STEP 20 of FIG. In subsequent STEP 21, the cooking control unit 51 determines whether or not a timer time change operation has been performed by the UP switch 63 or the DOWN switch 64 of the operation unit 14L for the left stove 4L.

  When the timer time is changed, the process proceeds to STEP 22 and the cooking control unit 51 sets the timer time according to the operation of the UP switch 63 or the DOWN switch 64. When the ignition / extinguish button 10L of the left stove 4L is turned on in the next STEP 23, the process proceeds to STEP 24, and the cooking control unit 51 starts the cooking operation in the “noodle bowl mode” (timer time set).

  On the other hand, when there is no operation for changing the timer time in STEP 21, the process branches to STEP 30, and when the ignition / fire extinguishing button 10L of the left stove 4L is turned on, the process proceeds to STEP 31, and the cooking control unit 51 sets the initial time as the timer time. Start cooking operation in “Moodle bowl mode” (initial time). If the left stove 4L ignition / fire extinguishing button 10L is not ON in STEP 30, the process returns to STEP 7 in FIG.

[3. Cooking operation by mode with noodle bowl]
Next, according to the flowchart of FIG. 5, the details of the cooking operation by the “noodle bowl mode” will be described. It should be noted that the cooking operation by the “noodle bowl mode” and the cooking operation by the “noodle bowl large mode” are executed in the same procedure except that the setting of the heating amount (thermal power and heating time) by the left stove 4L is different.

  In STEP 40 of FIG. 5, the cooking control unit 51 performs an ignition process of the left stove 4L and starts heating the water in the pot WL as a cooking container.

  In the next STEP 41, the cooking controller 51 waits for the water in the pan WL to boil at the temperature detected by the temperature sensor 8L. The cooking control unit 51 proceeds to STEP 42 when the temperature sensor 8L detects boiling in STEP 41, and notifies the user that the water has boiled by a buzzer sound and voice in STEP 42. The processing of STEP40 to STEP41 corresponds to the boiling step of the present invention. The temperature sensor 8L corresponds to the boiling detection means of the present invention.

  In the process where the water contained in the cooking container is heated to boiling, a sound such as “buzzing” or “buzzing” is generated from the pot WL with the generation of water vapor. In the next STEP 43, the cooking control unit 51 detects the sound generated near the left stove 4L as the first boiling sound by the microphone 44L, and records the first boiling sound in the recording unit 52 in STEP 44. In the next STEP 45, the cooking control unit 51 detects the sound generated near the left stove 4L as the second boiling sound by the microphone 44L.

  When the user who recognizes that the water in the pot WL has boiled is put into the pot WL and the timer switch 61 is operated, cooking with the noodle bowl is started. That is, when the timer switch 61 is operated in STEP 46, the process proceeds to STEP 47. And when a user throws noodles into the pot WL, the temperature of the water in the pot WL falls, and the boiling sound disappears temporarily or weakens.

  In STEP 47, the cooking control unit 51 starts a countdown of the cooking timer. In subsequent STEP 48, when Z seconds (for example, 10 seconds) have elapsed from the detection of boiling, the process proceeds to STEP 49 to execute the process with the noodle bowl. In STEP 49, the cooking control unit 51 heats the noodles in the pan WL while adjusting the heating power of the left stove 44 so that the water in the pan WL is boiled.

  In addition, when the cooking controller 51 starts the cooking timer in STEP 47, the cooking control unit 51 executes the processing of STEP 50 in parallel with the processing of STEP 48 to STEP 49. Then, when the cooking timer expires in STEP 50, the process proceeds to STEP 51, and the cooking control unit 51 extinguishes the left stove 4L.

  On the other hand, when the timer switch 61 is not operated in STEP 46, the process proceeds to STEP 60. In this case, it is assumed that the user has forgotten to put in noodles or has forgotten to operate the timer switch 61.

  In STEP60, the cooking control unit 51 compares the first boiling sound recorded in the recording unit 52 with the second boiling sound detected by the microphone 44L, and the second boiling sound changes from the first boiling sound. If it is determined that the noodles are present, it is recognized that the noodles are put in the pot WL, and the process proceeds to STEP 47. Moreover, when the cooking control part 51 discriminate | determines in STEP60 that the 2nd boiling sound has not changed from the 1st boiling sound, it progresses to STEP61.

  The process of STEP 60 corresponds to the to-be-cooked material input recognition process of the present invention. Further, the process proceeds to STEP 47 after STEP 60, and STEP 49 performed thereafter corresponds to the process of the present invention. In STEP 60, whether or not the second boiling sound is changed from the first boiling sound by the cooking control unit 51 is determined, for example, by comparing the sound volume or the presence or absence of sound in a specific frequency range. be able to.

  In STEP61, when 10 minutes have passed since the boiling detection time, the process proceeds to STEP62, and the cooking control unit 51 extinguishes the left stove 4L. If the elapsed time from the boiling detection time is less than 10 minutes in STEP 46, the process proceeds to STEP 63, the heating power of the left stove 4L is adjusted so that the boiling state of the water in the pot WL is maintained, and the process proceeds to STEP 45. .

  According to the cooking device 1 of the present embodiment, the cooking controller 51 forgets to operate the timer switch 61 after throwing noodles into the pot WL by determining a change in boiling sound caused by throwing noodles. Even if it is a case, a process can be reliably performed with the noodle bowl which controls the heating power of the left stove L so that blow-off is suppressed.

  In addition, in the cooking device 1 of the present embodiment, the left stove 4L is maintained so that the water in the pan WL is boiled until the change in the boiling sound is determined after the boiling is detected. The heating power is adjusted. Thereby, the state where the volume of the boiling sound is high can be maintained, and the change of the boiling sound detected by the microphone 44L can be easily determined.

  In addition, 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.

  In the present embodiment, the temperature sensor 8 is used as the boiling detection means of the present invention. However, the microphone 44 may be used as the boiling detection means to detect a boiling sound due to boiling of water.
