Description

  The present invention relates to a gas stove that notifies cooking timing for executing a predetermined process on a cooked product, and notifies thermal power switching when the thermal power is increased by automatic thermal power adjustment control.

  Conventionally, a gas stove that can be cooked in an automatic cooking mode including an automatic heating power adjustment control that includes a temperature detection means for detecting the temperature of the cooking container and increases or decreases the heating power of the stove burner so that the detected temperature becomes the target heating temperature. Are known. Also, when cooking food such as hamburgers and hot cakes that need to be heated on each side with a gas stove that can be cooked in the automatic cooking mode as described above, audio information such as predetermined voice guidance and buzzer sound Thus, there is known a gas stove that informs the timing of turning over the food (for example, Patent Document 1).

  On the other hand, in the automatic thermal power adjustment control, when the user does not intend, the thermal power of the combustor is increased or decreased. Therefore, if the heating power suddenly increases when increasing the heating power of the stove burner, the user is likely to be surprised or confused. From this point of view, when increasing the thermal power of the stove burner by automatic thermal power adjustment control, similarly, a gas stove has been proposed in which thermal power switching is notified in advance by voice information such as predetermined voice guidance and buzzer sound (for example, patents) Reference 2).

Japanese Patent No. 5556353 Japanese Patent Laying-Open No. 2015-1351

  However, when the notification of the timing for performing predetermined processing such as turning over the cooked food as described above is applied to a gas stove that notifies the switching of the thermal power when the automatic thermal power adjustment control is performed, the notification May overlap. For this reason, there are cases where it is difficult for the user to hear the timing notification or the notification is confused. It is conceivable to set different audio information for the timing notification and the thermal power switching notification, but since the timing notification is performed when cooking has progressed to some extent, automatic thermal power adjustment control is performed before the timing notification. If this happens, the user may get used to the notification of thermal power switching and may miss the timing notification.

  This invention solves the said subject, and the objective of this invention is the gas stove in which a thermal-power switching notification is performed when increasing a thermal power by automatic thermal power adjustment control, and the timing which performs predetermined processing with respect to a foodstuff. When performing the timing notification for notification, the user can surely recognize the timing notification, can proceed with cooking smoothly, and ensure high safety.

According to a first aspect of the present invention,
A cooker that heats the cooking container containing the food,
Temperature detecting means for detecting the temperature of the cooking container;
An informing means for informing predetermined audio information;
Automatic thermal power adjustment control means for performing automatic thermal power adjustment control for increasing or decreasing the thermal power of the burner so that the detected temperature detected by the temperature detection means becomes the target heating temperature;

When cooking timing comes while cooking is being performed in the automatic cooking mode, until the predetermined processing end timing arrives, the heating power of the cooker burner is fixed at a predetermined low heating power, and the heating power switching audio information is not notified, A gas stove having a control configuration for informing cooking timing audio information is provided.

  According to the gas stove, when the cooking timing for executing a predetermined process on the cooked food when cooking is performed in the automatic cooking mode, the heating power of the stove burner is reduced until the predetermined processing end timing arrives. Since the cooking timing audio information is notified without fixing the thermal power switching audio information while fixing to a predetermined low heating power, it is possible to avoid the overlapping of the notification of the thermal power switching audio information and the cooking timing audio information. Therefore, the user can surely hear the cooking timing voice information without confusion between the thermal power switching voice information and the cooking timing voice information. In addition, when the cooking timing for executing the processing on the cooked food arrives, the heating power of the stove burner is fixed at a predetermined low heating power until the processing end timing arrives. However, the user does not feel surprised or confused.

Preferably, the gas stove according to the first aspect further includes
When the advance timing before the arrival of the cooking timing arrives, the advance timing notification control means for notifying the predetermined advance timing audio information from the notification means,
If the advance timing arrives when cooking is performed in the automatic cooking mode, the fire power of the control burner is fixed to a low heating power until the processing end timing arrives, and the fire timing switching audio information is not notified, and the advance timing audio information And it has the control structure which alert | reports cooking timing audio | voice information.

  According to the gas stove, when the advance timing arrives when cooking is performed in the automatic cooking mode, the heating power of the stove burner is fixed to a predetermined low heating power until the processing end timing comes, and the thermal power switching audio information Therefore, the user is not confused with the thermal power switching voice information and the preliminary timing voice information, and only the cooking timing voice information is provided after the notification of the preliminary timing voice information. Since it is notified, it is possible to make the user recognize the arrival of the cooking timing more reliably. In addition, in the case of cooking that requires a predetermined preparation for processing, the preparation time can be secured by informing the advance timing audio information in advance. Furthermore, when the advance timing arrives, the power of the stove burner is fixed at a low power until the end of processing ends, so the user is surprised even when the user is near the gas stove for processing and preparation. I don't feel puzzled.

According to a second aspect of the present invention,
A cooker that heats the cooking container containing the food,
Temperature detecting means for detecting the temperature of the cooking container;
An informing means for informing predetermined audio information;
Automatic thermal power adjustment control means for performing automatic thermal power adjustment control for increasing or decreasing the thermal power of the burner so that the detected temperature detected by the temperature detection means becomes the target heating temperature;
Cooking mode selection means for setting an automatic cooking mode in which automatic heating power adjustment control is performed during cooking;
In the case where the heating power of the control burner is increased by a predetermined notification heating power change amount or more by performing automatic heating power adjustment control, a heating power switching notification control means for notifying predetermined heating power switching voice information from the notification means,
Cooking timing notification control means for informing the predetermined cooking timing voice information from the notification means when the cooking timing for performing the predetermined processing on the cooked food arrives,
When the cooking timing comes when cooking is being performed in the automatic cooking mode, when increasing the thermal power of the stove burner until the predetermined processing end timing arrives, increase the thermal power below the amount of required thermal power change, A gas stove having a control configuration for notifying the heating power switching sound information but notifying the cooking timing sound information is provided.

  According to the gas stove, when the cooking timing for executing a predetermined process on the cooked food when cooking is performed in the automatic cooking mode, the heating power of the stove burner is reduced until the predetermined processing end timing arrives. Even when increasing, it is necessary to alert the user to change the heating power of the control burner with an amount of change smaller than the amount of required heating power change, not to notify the heating power switching audio information, but to notify the cooking timing audio information In addition, it is possible to avoid overlapping notifications of the thermal power switching voice information and the cooking timing voice information. Therefore, the user can surely hear the cooking timing voice information without confusion between the thermal power switching voice information and the cooking timing voice information. In addition, when the cooking timing for executing the process on the cooked food arrives, the user increases the heating power of the stove burner with a smaller amount of change than the notification required thermal power change amount until the processing end timing arrives. Even if it is in the vicinity of a gas stove to do so, the user is unlikely to be surprised or confused. Furthermore, since the heating power of the cooker burner is increased or decreased even after the cooking timing has come, cooking of the food can be smoothly advanced.

Preferably, the gas stove according to the second aspect further includes
When the advance timing before the arrival of the cooking timing arrives, the advance timing notification control means for notifying the predetermined advance timing audio information from the notification means,
When the advance timing arrives when cooking is being performed in the automatic cooking mode, when increasing the thermal power of the control burner until the processing end timing arrives, the thermal power is increased with less than the required thermal power change amount, and the thermal power switching sound It has a control configuration for notifying information but notifying advance timing sound information and cooking timing sound information.

  According to the gas stove, when the advance timing arrives when cooking is being performed in the automatic cooking mode, even when the heating power of the stove burner is increased until the processing end timing is reached, the amount of change is not greater than the required heating power change amount. Since the thermal power of the burner is switched according to the amount of change, the thermal power switching voice information is not notified, and the prior timing voice information is notified, so the user does not confuse the thermal power switching voice information with the preliminary timing voice information, and the prior timing After the notification of the audio information, only the cooking timing audio information is notified, so that the user can be made to recognize the arrival of the cooking timing more reliably. In addition, in the case of cooking that requires a predetermined preparation for processing, the preparation time can be secured by informing the advance timing audio information in advance. Furthermore, when the pre-timing audio information is notified, the thermal power of the conrober is increased by a smaller amount of change than the amount of required thermal power change until the processing end timing arrives. Even in the vicinity of a gas stove, users are less likely to be surprised or confused. And even after the advance timing has arrived, the cooking power of the cooker can be smoothly increased because the heating power of the burner is increased or decreased.

As described above, according to the present invention, attention is paid to the user when the cooking timing audio information for notifying that the cooking timing for performing the predetermined process on the cooked food has arrived, and the heating power of the burner is increased. Can be avoided. Thereby, it is possible to prevent the notification of the cooking timing voice information from being missed and the confusion between the cooking timing voice information and the thermal power switching voice information, so that the user can surely recognize the cooking timing voice information. Therefore, the user can proceed with cooking smoothly.
In addition, according to the present invention, when the advance timing before the cooking timing arrives, the thermal power switching voice information is not notified, so that it is possible to avoid bothersomeness and familiarity with notification due to repeated notification.
Furthermore, when the cooking timing or advance timing arrives, the heating power of the cono burner is fixed at a low heating power or the heating power of the combo burner is increased below the notification heating power change amount required, so that there is little surprise or confusion for the user.
Therefore, according to the present invention, a user-friendly and highly safe gas stove can be provided.

It protrudes to a high position and is configured to be pushed down under the load of the cooking container when the cooking container is placed on the virtues 35, 36 and 37. In addition, ignition electrodes and thermocouples, which will be described later, are disposed at positions near the flame holes of the respective burners 31, 32, and 33. The temperature sensors 31a, 32a, 33a, the ignition electrode, and the thermocouple are connected to the controller 12 described later.

  A stove operation unit 23 located on the right side of the open / close door 21 of the grill cabinet 2 includes a power switch 29 and operation knobs 24, 25, 26 having both the function of turning on / off the stove burners 31, 32, 33 and adjusting the thermal power. Is arranged. Each of the operation knobs 24, 25, and 26 is changed into two states, that is, a use state that protrudes from the stove operation unit 23 and a non-use state that is flush with the stove operation unit 23 due to repeated pushing operations. Yes. Further, the stove operation unit 23 includes a speaker 27 adjacent to the power switch 29. Further, below the operation knobs 24, 25, and 26, an operation unit 39 for performing various cooking with the stove burners 31, 32, and 33 is provided.

  As shown in FIG. 2A, the operation unit 39 is provided with various touch panel switches for the respective burners 31, 32 and 33. For example, an operation unit for the right stove provided with the stove burner 32 includes an auto menu switch 391 for an automatic cooking mode, a temperature setting switch 392, a timer switch 393 for automatically cooking grilled food, stewed cooking, and the like. In addition, when the hot water switch 394 or the auto menu switch 391 is selected, a baking condition selection switch 395 for setting the baking and finishing of the cooked food in each automatic cooking mode is provided.

  In the gas stove of the present embodiment, when the user operates the auto menu switch 391 to perform cooking in the automatic cooking mode, for example, as shown in FIG. 2B, hamburger, grilled dumplings, curry, etc. are registered. The type of cooking in the automatic cooking mode is alternatively selected and displayed on the display unit 300. In cooking in which baking conditions can be selected, when the user operates the baking condition selection switch 395, strong, standard, and weak baking adjustments are alternatively selected and displayed on the display unit 300.

  FIG. 3 is a circuit diagram of the stove burner 32. In addition, since the stove burners 31 and 33 have the same circuit, these are omitted, and the stove burner 32 will be mainly described below. As shown in FIG. 3, a gas supply pipe 100 that supplies fuel gas is connected to the stove burner 32, and the original electromagnetic valve 4 and the flow rate change valve 5 are interposed in the gas supply pipe 100. The flow rate change valve 5 is a conventionally known electric valve. By changing the opening degree of the flow rate change valve 5 via the stepping motor 14, the level of the heating power of the cono burner 32 is changed from “1” (minimum) to “1”. It can be switched to 9 levels up to 9 "(maximum).

  The controller 12 includes the original solenoid valve 4, the stepping motor 14, the ignition electrode 32b, the thermocouple 32c, the already-described point fire extinguishing switch 25, the speaker 27, the operation unit 39, the temperature sensor 32a, the display unit 300, and the like. Connected through.

  The controller 12 controls the sound information to be notified from the speaker 27 and the thermal power control unit 120 that controls the thermal power of the stove burner 32 by adjusting the opening degree of the original electromagnetic valve 4 and the flow rate change valve 5 as functional constituent means. A notification control unit 121, a memory 126 storing a predetermined control program, various set values, a plurality of audio information having different notification contents, and the like, and a timer 127 are provided.

  The thermal power control unit 120 ignites and extinguishes the stove burner 32 in accordance with a signal output from the fire extinguishing switch 25, or based on the detected temperature and cooking time detected by the temperature sensor 32 a. Thermal power adjustment control to increase or decrease the thermal power of is performed. Specifically, when the user presses the fire extinguishing switch 25 with the cooking container 9 placed on the virtues 36, the thermal power control unit 120 opens the original electromagnetic valve 4 and the predetermined ignition thermal power. When the opening degree of the flow rate change valve 5 is adjusted so that the gas supply flow rate is obtained, the ignition electrode 32b is operated to perform ignition processing, and the user presses the point fire switch 25 during fire extinguishing, a thermal power control unit 120 closes the original solenoid valve 4 and performs a fire extinguishing process. In addition, when the user operates the auto menu switch 391 or the baking condition selection switch 395 of the operation unit 39 to select the cooking condition such as the cooking type or baking in the automatic cooking mode, according to a predetermined control program, The opening degree of the flow rate change valve 5 is adjusted based on the detected temperature and cooking time detected by the temperature sensor 32a to increase or decrease the heating power of the stove burner 32.

  When the thermal power of the control burner 32 is increased by a predetermined amount of required thermal power change or more by performing automatic thermal power adjustment control by the thermal power controller 120, the notification control unit 121 performs predetermined thermal power switching audio information (for example, “large fire” Voice guidance and “discontinuous buzzer sound for a certain period of time” are output from the speaker 27. In addition, when the user operates the auto menu switch 391 of the operation unit 39 and the type of cooking that is required to perform a predetermined process on the food during cooking is selected, When it comes to a predetermined pre-timing, pre-timing audio information (for example, for hamburger, “It ’s time to turn the ingredients over soon”), for dumplings, “please get ready to pour water”, for curry, “soon The voice guidance of “It is time” and the continuous buzzer sound for a certain time) are output from the speaker 27. Furthermore, when the kind of cooking which needs to perform a predetermined | prescribed process with respect to a cooking item is selected during cooking, the alerting | reporting control part 121 will become cooking timing audio | voice information (for example, hamburger's information), when a predetermined cooking timing comes. For example, “Turn the ingredients over and put a lid on”. For dumplings, “Pour water and put on the lid.” For curry, “Stir the ingredients and cap the lid.” A voice guidance or a continuous buzzer sound for a predetermined time longer than the previous timing is output from the speaker 27.

  Next, a control operation when a hamburger that is turned over during cooking is selected with the auto menu switch 391 of the gas stove according to the present embodiment will be described with reference to FIGS. In FIG. 6, the solid line indicates the temperature change of the detected temperature detected by the temperature sensor 32 a, and the alternate long and short dash line indicates the heating power of the stove burner 32.

  When the user turns on the power switch 29 and selects the cooking type (for example, hamburger) with the auto menu switch 391 of the operation unit 39 and the baking condition selection switch 395, the memory is selected. 126, in order to increase or decrease the heating power of the burner 32 so that the detected temperature detected by the temperature sensor 32 a becomes the target heating temperature when the initial heating power Pa and the automatic heating power adjustment control are performed according to the cooking conditions. Upper and lower limit switching temperatures T1 to T4, upper and lower limit switching temperatures P1 to Pe that are switched at upper and lower limit switching temperatures T1 to T4, cooking timing ts for performing predetermined processing on the cooked food, cooking Pre-timing tp a predetermined time before timing ts, processing end timing tw, fire by automatic heating power adjustment control Temperature control end timing ty for ending the change, low thermal power Ps set in the combustor 32 from the arrival of the pre-timing tp to the processing end timing tw, baking power Pf set in the combustor 32 after the temperature control end timing ty Various setting values such as the total cooking time tz are read (steps S1 to S5).

  Next, when the user puts the food into the cooking container 9 and ignites the point extinguishing switch 25, the timer 127 is started, the measurement of the elapsed time tx is started, and a predetermined initial thermal power Pa (for example, , 1,500 kcal / hr of large fire), automatic cooking is started (steps S6 to S8). When automatic cooking is started, the front-side automatic thermal power adjustment control program shown in FIG. 5A is activated, and detection is performed until a predetermined preliminary timing tp (for example, 200 seconds after the start of cooking) comes from the start of cooking. The heating power of the burner 32 is increased or decreased so that the temperature Tx becomes the target heating temperature (for example, 178 ° C.) (steps S9 and S10).

  As shown in FIG. 5A, in the surface-side automatic heating power adjustment control, when the detected temperature Tx reaches the surface-side upper limit switching temperature T1 (for example, 182 ° C.), the heating power of the stove burner 32 is changed to the surface-side upper limit switching heating power Pb. (For example, a small fire of 300 kcal / hr) is switched (steps S101 to S102). When the heating power of the burner 32 is switched to the surface side upper limit switching heating power Pb, as shown in FIG. 6, the temperature curve of the detected temperature Tx decreases after showing the peak temperature. Then, when the detected temperature Tx becomes the surface side lower limit switching temperature T2 (for example, 176 ° C.) due to the reduction of the heating power of the stove burner 32, the heating power of the stove burner 32 is changed to a predetermined surface side lower limit switching heating power Pc (for example, 1,500 kcal / (large fire of hr) (steps S103 to S104). At this time, the amount of change (for example, 1,500 kcal / hr-300 kcal / hr = 1,200 kcal / hr) when increasing the thermal power of the conburner 32 by the automatic thermal power adjustment control to the surface side lower limit switching thermal power Pc is a predetermined value. If the required thermal power change amount S (for example, 1,000 kcal / hr) or more is required, thermal power switching voice information (for example, voice guidance for “change to large fire”) is notified from the speaker 27 (steps S105 to S106). .

  When the pre-timing tp arrives when the heating power of the burner 32 is increased or decreased so that the detected temperature Tx becomes the surface-side target heating temperature by the automatic heating power adjustment control as described above (Yes in step S9), the surface The side automatic heating power adjustment control is terminated, and pre-timing audio information (for example, audio guidance of “it is time to turn over the food soon”) is notified from the speaker 27 (step S11). Thereby, the user can prepare for the process with respect to a foodstuff.

  Further, when the advance timing tp arrives, the heating power of the burner 32 is switched to a predetermined low heating power Ps (for example, medium heat of 800 kcal / hr) (step S12). Note that the low thermal power Ps, which is a fixed thermal power, is the thermal power of the stove burner 32 that does not increase the detected temperature Tx, and can be set as appropriate according to the type of cooking. Next, it is determined whether or not the cooking timing ts (for example, 240 seconds after the start of cooking) has arrived, and when the cooking timing ts has arrived, cooking timing audio information (for example, “turn the food over and close the lid”). Voice guidance) is notified (steps S13 to S14). Thereby, the user can perform a predetermined | prescribed process with the optimal timing with respect to a foodstuff.

  After the cooking timing ts has arrived, the heating power of the conoburner 32 is fixed at the low heating power Ps until a predetermined processing end timing tw (for example, 300 seconds after the start of cooking) comes. When the processing end timing tw arrives, the back side automatic heating power adjustment control program shown in FIG. 5B is activated, and a predetermined temperature adjustment end timing ty (for example, 400 seconds after the start of cooking) arrives. Until this is done, the heating power of the burner 32 is increased or decreased so that the detected temperature Tx becomes the rear surface side target heating temperature (for example, 162 ° C.) (steps S16 and S17).

As shown in FIG. 5B, in the back side automatic thermal power adjustment control, first, the detected temperature Tx when the processing end timing tw arrives is the back side upper limit switching temperature T3 (for example, 164 ° C.) or higher, or the back side lower limit. It is determined whether the temperature is lower than the switching temperature T4 (for example, 160 ° C.) (steps S111 to S112). If the detected temperature Tx is equal to or higher than the back-side upper limit switching temperature T3 (Yes in step S111), the heating power of the combustor 32 is switched to the back-side upper limit switching thermal power Pd (for example, a small fire of 300 kcal / hr) ( In step S117), if the detected temperature Tx is equal to or lower than the back side lower limit switching temperature T4 (Yes in step S112), the heating power of the stove burner 32 is changed to the back side lower limit switching thermal power Pe (for example, a large fire of 1,500 kcal / hr). It is switched (step S113). At this time, if the amount of change when increasing to the back side lower limit switching thermal power Pe is equal to or greater than the required notification thermal power variation S, the thermal power switching voice information from the speaker 27 (for example, voice guidance “change to large fire”) Is notified (steps S114 to S115). In the present embodiment, the amount of change (1,500 kcal / hr-800 kcal / hr = 700 kcal / hr) when increasing from the low heating power Ps to the back side lower limit switching heating power Pe is the previously-notified required heating power change amount. Since it is less than S, the thermal power switching voice information is not notified.
Then, until the predetermined temperature adjustment end timing ty (for example, after 400 seconds from the start of cooking), when the detected temperature Tx becomes the back side upper / lower limit switching temperature T3, T4, the heating power of the combustor 32 is increased on the back side, respectively. Automatic thermal power adjustment control for switching to the lower limit switching thermal power Pd, Pe is executed. Since the amount of change when increasing the heating power of the control burner 32 to the back side lower limit switching heating power Pe by this automatic heating power adjustment control is set to be equal to or greater than the previously-notified required heating power change amount S, the speaker is similar to the above. 27 is notified of the thermal power switching voice information (steps S116 to S121).

  When the predetermined temperature adjustment end timing ty arrives while the back side automatic heating power adjustment control is being performed, until the predetermined total cooking time tz (for example, 840 seconds after the start of cooking) arrives, The cooked product is heated by fixing the heating power to a predetermined baking power Pf (for example, a small fire of 300 kcal / hr) (steps S18 to S19).

  As described above in detail, according to the present embodiment, in the case where the thermal power of the control burner 32 is increased by a required thermal power change amount or more by automatic thermal power adjustment control so that the detected temperature becomes the target heating temperature, Since the switching voice information is informed, the user can be alerted.

  Further, in the present embodiment, when the pre-timing arrives, the heating power of the cono burner 32 is fixed to a predetermined low heating power, so that the heating power by the heating power change until the predetermined processing end timing comes after the pre-timing arrives. Switching voice information is not notified. Therefore, it is possible to prevent the heating power switching sound information and the cooking timing sound information from being reported in duplicate within a short time. In addition, when the advance timing arrives, only the advance timing audio information and the cooking timing audio information are notified. Therefore, the user can reliably prepare the cooking timing audio information without confusion between the audio information and the thermal power switching audio information. Can be heard. In addition, since only the pre-timing audio information is notified until the cooking timing audio information is notified, the user does not feel bothered by the plurality of audio information, and the user's habituation to the notification can be prevented. . Thereby, a user can be made to recognize arrival of cooking timing more reliably. Furthermore, since the pre-timing audio information is notified prior to the notification of the cooking timing audio information, it is possible to secure time for preparation of cooking utensils and preparation of water supply for processing.

  In addition, according to the present embodiment, when the pre-timing audio information is notified, since the thermal power of the cono burner 32 is fixed at low thermal power until the processing end timing arrives, the user performs processing. Even in the vicinity of a gas stove, the user does not feel surprised or confused.

  Therefore, according to the present embodiment, it is possible to perform cooking smoothly in cooking in the automatic cooking mode in which predetermined processing is performed, and it is possible to provide a gas stove that is excellent in user convenience and excellent in safety. it can.

(Embodiment 2)
Since this embodiment is the same as the first embodiment except that the thermal power of the cono burner 32 is less than the required thermal power change amount when the advance timing arrives, the same configuration will be described. Omitted and only the different parts are described.

  7 and 8 are flowcharts showing an example of a control operation for performing automatic cooking for executing a predetermined process on a cooked product during cooking on the gas stove according to the present embodiment, and FIG. 9 is a cooking time. The temperature characteristic with respect to and the change of the heating power of the stove burner 32 are shown.

  When the user selects a cooking type (for example, hamburger) or baking degree (for example, standard) in a predetermined automatic cooking mode, various setting values other than the low heating power Ps in the first embodiment are stored in advance from the memory 126. The switching time ti in the thermal power switching control from the arrival of the timing tp to the arrival of the processing end timing tw, and the set values of the first and second switching thermal powers Pt and Pu of the cono burner 32 switched every switching time ti. Are read (steps S31 to S35).

  Next, when the user puts the food into the cooking container 9 and ignites the point fire switch 25 to start automatic cooking, as in the first embodiment, until the advance timing tp arrives. When the heating power of the burner 32 is increased or decreased so that the detected temperature Tx becomes the target heating temperature on the surface side by the surface-side automatic heating power adjustment control (steps S201 to S206) shown in FIG. If the amount of change in the thermal power is equal to or greater than the predetermined required thermal power change amount S, the thermal power switching audio information is notified from the speaker 27 (steps S39 to S40).

  If the pre-timing tp arrives while the front side automatic heating power adjustment control is being performed (Yes in step S39), the pre-timing audio information is notified from the speaker 27 (step S41). In addition, the heating power switching control program shown in FIG. 8B is activated, and the heating power of the combustor 32 is increased or decreased until the processing end timing tw arrives (step S45).

  As shown in FIGS. 8B and 9, in the thermal power switching control program, when the preliminary timing tp arrives, the thermal power of the combustor 32 is switched to the first switching thermal power Pt (for example, a small fire of 600 kcal / hr). Thereafter, every time a predetermined switching time ti (for example, 20 seconds) elapses until the processing end timing tw arrives, the first switching heating power Pt and the second switching heating power Pu (for example, 1,000 kcal / hr) The firepower of the burner 32 is switched between (fire) and the fire (steps S231 to S234). The amount of change (for example, 1,000 kcal / hr−600 kcal / hr = 400 kcal / hr) when increasing the thermal power of the stove burner 32 from the first switching thermal power Pt to the second switching thermal power Pu is the required thermal power change amount S Since it is set to less than, the thermal power switching sound information is not notified from the speaker 27. The switching time ti and the first and second switching heating powers Pt and Pu are times and heating powers such that the detected temperature Tx does not exceed the detected temperature when the preliminary timing tp arrives, and can be set as appropriate according to the type of cooking. .

  When the cooking timing ts arrives while the heating power switching control is being performed, cooking timing audio information is notified from the speaker 27 (step ST43). Further, when the processing end timing tw arrives, the back side automatic heating power adjustment control program shown in FIG. 8C is started, and the detected temperature Tx becomes the back side target heating temperature from the start of cooking until the temperature adjustment end timing ty arrives. Thus, the heating power of the burner 32 is increased or decreased (steps S46 and S47).

As shown in FIG. 8C, in the back side automatic thermal power adjustment control, as in the first embodiment, the detected temperature Tx when the processing end timing tw arrives is the back side upper limit switching temperature T3 or higher, or the back side. It is determined whether the temperature is lower than the lower limit switching temperature T4 (steps S211 to S212). If the detected temperature Tx is equal to or higher than the rear surface side upper limit switching temperature T3 (Yes in step S211), When the detected temperature Tx is equal to or lower than the lower limit switching temperature T4 on the back side (Yes in step S212), the heating power of the combustor 32 is changed to the back side, if the heating power Pd (for example, a small fire of 300 kcal / hr) is switched (step S217). It is switched to the lower limit switching heating power Pe (for example, a large fire of 1,500 kcal / hr) (step S213). At this time, if the amount of change when increasing from the thermal power of the combustor 32 when the processing end timing tw arrives to the back side lower limit switching thermal power Pe is equal to or greater than the required thermal power change amount S, the thermal power switching audio information ( For example, the voice guidance “I will change to a big fire” is notified (steps S214 to S215). In the present embodiment, the amount of change (for example, 1,500 kcal / hr−600 kcal / hr = 900 kcal / hr) when increasing from the first switching thermal power Pt to the back side lower limit switching thermal power Pe is the same as described above. Since it is less than the notification thermal power change amount S, the thermal power switching audio information is not notified.
The subsequent back side automatic heating power adjustment control operation and the control operation after the end of processing timing tw are the same as those in the first embodiment.

  As described above in detail, according to the present embodiment, when the pre-timing arrives, even if the thermal power of the cono burner 32 is increased, the thermal power of the cono burner 32 with a smaller amount of change than the required thermal power change amount. And the thermal power switching voice information is not notified, but the preliminary timing voice information is notified. Therefore, the thermal power switching voice information due to the thermal power change is not notified until the predetermined processing end timing comes after the preliminary timing arrives. Therefore, it is possible to prevent the heating power switching sound information and the cooking timing sound information from being reported in duplicate within a short time. In addition, when the advance timing arrives, only the advance timing audio information and the cooking timing audio information are notified. Therefore, the user can reliably prepare the cooking timing audio information without confusion between the audio information and the thermal power switching audio information. Can be heard. In addition, since only the pre-timing audio information is notified until the cooking timing audio information is notified, the user does not feel bothered by the plurality of audio information, and the user's habituation to the notification can be prevented. . Thereby, a user can be made to recognize arrival of cooking timing more reliably. Furthermore, since the pre-timing audio information is notified prior to the notification of the cooking timing audio information, it is possible to secure time for preparation of cooking utensils and preparation of water supply for processing.

  In addition, according to the present embodiment, when the advance timing audio information is notified, the thermal power of the cono burner 32 is increased by a change amount smaller than the required notification thermal power change amount until the processing end timing arrives. Even if the user is in the vicinity of the gas stove for processing, the user is less likely to be surprised or confused. Furthermore, since the food can be heated at a constant temperature until the processing end timing after the advance timing has arrived, cooking can proceed smoothly.

  Further, according to the present embodiment, when the thermal power is increased by the automatic thermal power adjustment control at the required thermal power change amount or more, the thermal power switching sound information is notified, so that the user can be alerted.

  Therefore, according to the present embodiment, it is possible to perform cooking smoothly in cooking in the automatic cooking mode in which predetermined processing is performed, and it is possible to provide a gas stove that is excellent in user convenience and excellent in safety. it can.
