Further, ignition electrodes and thermocouples, which will be described later, are disposed in the vicinity of the dike holes of the furnace burners 31, 32, and 33. The temperature sensors 31a, 32a, and 33a, the ignition electrode, and the thermocouple are connected to a controller 12, which will be described later.

A power switch 29 and an operation knob (not shown) for attenuating the burner burners 31, 32, and 33 and having a function of adjusting the thermal power are provided in the stove operation portion 23, which is located on the right side of the opening 21 of the grill warehouse 2 24, 25 and 26 are disposed. The operation knobs 24, 25 and 26 are each configured to change from the use state protruding from the stove operation member 23 to the stow operation member 23 in a non-use state have. A speaker 27 is built in the stow operation portion 23 adjacent to the power switch 29. An operating unit 39 for cooking various kinds of stove burners 31, 32, and 33 is provided below the operating knobs 24, 25,

As shown in Fig. 2 (a), the operation unit 39 is provided with various kinds of touch panel type switches for the respective stove burners 31, 32, and 33.

In the gas stove of this embodiment, when the user operates the auto menu switch 391 to cook in the automatic cooking mode, for example, as shown in Fig. 2 (b), registration of a hamburger, The type of cooking in the automatic cooking mode is alternatively selected and displayed on the display unit 300. When the user operates the roasting condition selection switch 395 in the cooking mode in which the roasting condition is selectable, the roasting degree of the reinforcing, standard, and weakening is alternatively selected and displayed on the display unit 300.

3 is a circuit diagram of the stove burner 32. As shown in Fig. Since the stove burners 31 and 33 also have the same circuit, they are omitted, and the stove burner 32 will be mainly described below. 3, a gas supply pipe 100 for supplying fuel gas is connected to the stove burner 32, and a source solenoid valve 4 and a flow rate change valve 5 are provided in the gas supply pipe 100 . The flow rate change valve 5 is a conventionally known motorized valve and changes the degree of opening of the flow rate change valve 5 through the stepping motor 14 so that the level of the thermal power of the stove burner 32 becomes " 1 "(minimum) to" 9 "(maximum).

The controller 12 is connected to the controller 12 via the electromagnetic valve 4, the stepping motor 14, the ignition electrode 32b, the thermocouple 32c, the ignition switch 25 described above, the speaker 27, A temperature sensor 32a, a display unit 300, and the like are connected through an electric wiring.

The controller 12 includes a thermal power control unit 120 for controlling the thermal power of the stove burner 32 by adjusting the openings of the source solenoid valve 4 and the flow rate changing valve 5, A memory 126 in which a predetermined control program, a variety of setting values, a plurality of pieces of audio information having different notification contents, and the like are stored, and a timer 127 is provided.

The thermal power control unit 120 controls the ignition timing of the stove burner 32 based on the viscous agent for igniting and extinguishing the stove burner 32 or the ignition timing of the stove burner 32 based on the detection temperature and the cooking time detected by the temperature sensor 32a The thermal power adjustment control for increasing or decreasing the thermal power of the stove burner 32 is performed. Specifically, when the user depresses the ignition switch 25 while the cooking container 9 is placed on the container holder 36, the thermal power control unit 120 opens the original electromagnetic valve 4, The opening degree of the flow rate changing valve 5 is adjusted so that the gas supply flow rate of the predetermined ignition power is obtained and the ignition electrode 32b is operated to perform the ignition processing so that the ignition switch 25 is pressed When operated, the thermal power control unit 120 closes the original electromagnetic valve 4 and extinguishes the extinguishing process. When the user operates the auto menu switch 391 or the roasting condition selection switch 395 of the operation unit 39 to select a cooking condition such as the type of cooking or the degree of cooking in the automatic cooking mode, The opening degree of the flow rate changing valve 5 is adjusted based on the detection temperature and the cooking time detected by the temperature sensor 32a to increase or decrease the thermal power of the stove burner 32. [

When the thermal power of the stagnant burner 32 is increased beyond the predetermined main notification thermal power change amount by performing the automatic thermal power adjustment control in the thermal power control section 120, the notification control section 121 outputs predetermined thermal power conversion sound information (for example, Quot ;, "change to big bang ", or discontinuous buzzer sound for a predetermined time). When the user operates the auto menu switch 391 of the operation unit 39 to select the kind of the cooking that needs to perform predetermined processing on the food during cooking, When it comes to pre-timing, pre-timing audio information (for example, in the case of a hamburger, is "time to flip the ingredients soon", in the case of dumplings, "prepare to boil water more", in the case of curry, "And a continuous buzzer sound for a predetermined time) from the speaker 27. [0050] When the type of cooking required to perform a predetermined process on the food is selected during cooking, when the predetermined cooking timing is reached, the notification control unit 121 sets the cooking timing audio information (for example, in the case of a hamburger, In the case of the dumplings, please pour more water and cover the lid, and in the case of curry, use the voice guidance of "Please mix the ingredients and cover the lid" And a continuous buzzer sound for a long period of time) from the speaker 27.

Next, the control operation in the case where the automatic menu switch 391 of the gas stove of this embodiment is used to select a hamburger to be subjected to flipping processing during cooking will be described with reference to Figs. 4 to 6. Fig. 6, the solid line represents the temperature change of the detection temperature detected by the temperature sensor 32a, and the one-dot chain line represents the thermal power of the stove burner 32. In Fig.

After the user turns on the power switch 29, the degree of baking with the type of cooking (for example, a hamburger) and the roasting condition selection switch 395 by the auto menu switch 391 of the operation unit 39 The initial heating power Pa in accordance with the cooking condition and the detected temperature detected by the temperature sensor 32a when the automatic heating force adjustment control is being performed are set at the target heating temperature The upper and lower switching power Pb-Pe of the stove burner 32, which is switched between the upper and lower switching temperatures T1 to T4 and the upper and lower switching temperatures T1 to T4 for increasing or decreasing the thermal power of the burner 32, , The cooking timing ts for performing a predetermined process on the food, the pre-timing tp, the process end timing tw, and the heating power change by automatic power adjustment control are terminated a predetermined time before the cooking timing ts The temperature control termination timing ty, the pre-timing tp, and the process termination timing tw, Various setting values such as the baking power Pf set in the baking burner 32 and all the cooking times tz are read after the low heating power Ps set at the knob 32 and the temperature regulation end timing ty Steps S1 to S5).

Next, when the user puts the food into the cooking container 9 and ignites the ignition switch 25, the timer 127 is started to measure the elapsed time tx and at the same time, The automatic cooking is started with the initial heating power Pa (e.g., large fire of 1,500 kcal / hr) (steps S6 to S8). When the automatic cooking is started, the front side automatic power adjustment control program shown in Fig. 5 (a) is activated and when a predetermined pre-timing tp (for example, after 200 seconds from the aperture stop) The heating power of the stove burner 32 is increased or decreased (steps S9 and S10) so that the detection temperature Tx becomes the front side target heating temperature (for example, 178 deg.

5A, in the surface side automatic power adjustment control, when the detection temperature Tx reaches the surface side upper limit switching temperature T1 (for example, 182 DEG C), the surface temperature of the stove burner 32 The thermal power is converted to the surface side upper limit conversion power Pb (for example, small fire of 300 kcal / hr) (steps S101 to S102). When the thermal power of the stove burner 32 is switched to the surface side upper limit switching power Pb, the temperature curve of the detection temperature Tx shows the peak temperature and then decreases as shown in Fig. When the detection temperature Tx reaches the surface side lower limit switching temperature T2 (for example, 176 deg. C) due to the lowering of the thermal power of the stove burner 32, the thermal power of the stove burner 32 reaches the predetermined surface side And converted into the lower limit conversion power Pc (for example, a large fire of 1,500 kcal / 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 stoker burner 32 by the automatic power adjustment control to the surface- (For example, voice guidance of "change to big fire") by the speaker 27 when the predetermined main notification power change amount S (for example, 1,000 kcal / hr) Steps S105 to S106).

When the pre-timing tp comes (Yes in step S9) when the thermal power of the stove burner 32 is being increased or decreased so that the detection temperature Tx becomes the front side target heating temperature by the automatic power adjustment control described above, The front side automatic power adjustment control is terminated and the speaker 27 is notified of the pre-timing audio information (for example, voice guidance of "soon to turn back the food") (step S11). Thus, the user can prepare the preparation for the food.

When the pre-timing tp arrives, the fire power of the stove burner 32 is switched to a predetermined low fire power Ps (for example, 800 kcal / hr) (step S12). The low heating power Ps as the fixed heating power is a thermal power of the stove burner 32 to such an extent that the detection temperature Tx does not rise and can be set appropriately according to the cooking type. Subsequently, it is judged whether or not the cooking timing ts (for example, after 240 seconds from the time of diaphragm) has arrived, and when the cooking timing ts comes, the cooking timing audio information (for example, Quot; turn over the material and cover the lid ") is notified (steps S13 to S14). Thereby, the user can perform predetermined processing for the food at the optimum timing.

After the cooking timing ts arrives, the heating power of the stove burner 32 is fixed to the low heating power Ps until a predetermined processing end timing tw (for example, after 300 seconds from the time of the iris) do. When the processing end timing (tw) comes, the back side automatic power adjustment control program shown in Fig. 5 (b) is started and the predetermined temperature control end timing ty (for example, The heating power of the stove burner 32 is increased or decreased (steps S16 and S17) until the detection temperature Tx becomes the back side target heating temperature (for example, 162 deg.

5 (b), in the back side automatic power adjustment control, the detection temperature Tx at the time when the first processing end timing (tw) reaches the back side upper limit switching temperature T3 (for example, 164 deg. C) Or below the lower limit switching temperature T4 (for example, 160 DEG C) (steps S111 to S112). When the detection temperature Tx is equal to or greater than the backside upper limit switching temperature T3 (Yes in step S111), the heating power of the stove burner 32 is lower than the backside upper conversion heat power Pd (for example, 300 kcal / hr (Step S112). If the detected temperature Tx is lower than the lower-side switching temperature T4 (Yes in step S112), the firepower of the stove burner 32 is switched to the lower- Pe) (for example, a large fire of 1,500 kcal / hr) (step S113). At this time, if the amount of change when increasing to the back side lower-limit conversion power Pe is equal to or larger than the main notification heat-power change amount S, the speaker 27 switches the fire-fighting conversation voice information (for example, Guidance) (steps S114 to S115). In this embodiment, the amount of change (1,500 kcal / hr-800 kcal / hr = 700 kcal / hr) at the time of increasing from the low heat power Ps to the backside lower conversion thermal power Pe is calculated as the above- (S), the fire fighting voice information is not notified.

When the detection temperature Tx reaches the upper and lower switching temperatures T3 and T4 on the back side until a predetermined temperature control termination timing ty (for example, after 400 seconds from the aperture stop) arrives, The automatic firepower adjustment control for switching the thermal power of the burner 32 to the upper and lower switching thermal power Pd, Pe on the rear surface side is executed. Since the amount of change when increasing the thermal power of the stoker burner 32 by the automatic power adjustment control to the backside lower switching power Pe is set to be equal to or larger than the aforementioned main notification heat power variation amount S, Similarly, the speaker 27 notifies the fire-fighting voice information (steps S116 to S121).

When a predetermined temperature adjustment termination timing (ty) comes when the back side automatic power adjustment control is being performed, until a predetermined total cooking time tz (for example, after 840 seconds from the aperture stop) comes The cooking pot is heated by fixing the heating power of the cooking stove burner 32 to a predetermined cooking power Pf (for example, a small fire of 300 kcal / hr) (steps S18 to S19).

As described in detail above, according to the present embodiment, when the firepower of the stove burner 32 is increased to the main notification power change amount or more by the automatic firepower adjustment control so that the detection temperature becomes the target heating temperature, The user can be alerted.

In the present embodiment, in order to fix the firepower of the stove burner 32 to a predetermined low firepower when the pre-timing comes, the firepower is changed to the firepower until the predetermined processing end timing comes after the pre- Is not notified. Therefore, it is possible to prevent the fire-fighting voice information and the cooking timing voice information from being repeatedly notified in a short period of time. In addition, when the pre-timing comes, only the pre-timing audio information and the cooking timing audio information are notified so that the user can reliably recognize the cooking timing audio information without confusing these audio information with the fire-fighting conversation audio information . In addition, since only the pre-timing audio information is not notified until the cooking timing audio information is not notified, the user does not feel troublesome by the plurality of audio information, and the user's habit of the notification can be prevented. This makes it possible to more reliably recognize the arrival of the cooking timing to the user. Since the pre-timing audio information is notified before the notification of the cooking timing audio information, it is possible to secure time for preparing the cooking utensil for processing and preparing water for further processing.

Further, according to the present embodiment, when the pre-timing audio information is notified, the firepower of the stove burner 32 is fixed at a low firepower until the end of processing ends, so that, Even in the vicinity, the user does not feel surprised and embarrassed.

Therefore, according to the present embodiment, it is possible to provide a gas furnace which can be cooked smoothly in cooking in an automatic cooking mode in which a predetermined process is performed, excellent in usability of the user, and excellent in safety.

 (Example 2)

The present embodiment is the same as the first embodiment except that the firepower of the stove burner 32 is increased to less than the main notification power changing amount when the pre-timing comes, so that the description of the same configuration is omitted , Only the other parts will be described.

Figs. 7 and 8 are flow charts showing an example of a control operation for performing automatic cooking for performing a predetermined process on a food during cooking in the gas stove of this embodiment, and Fig. 9 is a flowchart showing an example of a control operation And a change in thermal power of the stove burner 32.

When the user selects the type of cooking (for example, a hamburger) or the degree of baking (for example, standard) in the predetermined automatic cooking mode, The switching time ti in the thermal power switching control until the arrival of the processing end timing tw after the arrival of the preliminary timing tp and the switching time ti, (32) The respective set values of the first and second conversion thermal power Pt and Pu are read (steps S31 to S35).

Subsequently, when the user puts the food into the cooking container 9 and ignites the ignition switch 25 to start the automatic cooking, as in the first embodiment, until the pre-timing tp comes The heating power of the stove burner 32 is increased or decreased so that the detection temperature Tx becomes the surface side target heating temperature by the surface side automatic power adjustment control (steps S201 to S206) shown in Fig. 8 (a) The fire-power conversion sound information is notified from the speaker 27 (steps S39 to S40).

If the pre-timing tp comes (YES in step S39) while the front side automatic power adjustment control is being performed, the speaker 27 notifies the pre-timing audio information (step S41). The thermal power conversion control program shown in Fig. 8 (b) is activated, and the thermal power of the stoker burner 32 is increased or decreased until the process end timing tw comes (step S45).

9 (b) and 9, in the thermal power conversion control program, when the pre-timing tp comes, the thermal power of the stove burner 32 reaches the first conversion thermal power Pt (for example, 600 kcal / (for example, 20 seconds) elapses until the end of the processing end timing (tw), and then the first switching power (Pt) is switched to the second switching power (Pt) The thermal power of the stove burner 32 is switched between the first switching power P0 and the second switching power P0 (for example, 1,000 kcal / hr) (steps S231 to S234). (For example, 1,000 kcal / hr-600 kcal / hr = 400 kcal / hr) when increasing the thermal power of the furnace burner 32 from the first conversion power Pt to the second conversion power Pu, The fire power conversion sound information is not reported from the speaker 27 because it is set to be less than the main notification heat power change amount S. The switching time ti and the first and second switching power Pt and Pu are a time and a thermal power such that the detection temperature Tx does not exceed the detection temperature at the time of the pre-timing tp, It can be set appropriately according to the kind.

When the cooking timing (ts) comes when the thermal power conversion control is being executed, the speaker 27 notifies the cooking timing audio information (step ST43). When the processing end timing (tw) comes, the back side automatic power adjustment control program shown in Fig. 8 (c) is started and the detection temperature Tx (Step S46 and step S47). The heating power of the stove burner 32 is increased or decreased in order to obtain the target side heating temperature.

As shown in Fig. 8C, in the back side automatic power adjustment control, the detection temperature Tx at the time when the processing end timing (tw) is equal to or more than the back side upper limit switching temperature T3 (Step S211 to S212). If the detected temperature Tx is equal to or greater than the backside upper limit switching temperature T3 (YES in step S211), it is determined whether or not the temperature of the stove burner 32 When the detected temperature Tx is lower than the lower-side switching temperature T4 (at step S212), the thermal power is switched to the upper-side switching thermal power Pd (for example, 300kcal / , The heating power of the stove burner 32 is switched to the back side lower limit switching power Pe (for example, large fire of 1,500 kcal / hr) (step S213). At this time, if the amount of change in the increase from the thermal power of the stoker burner 32 to the back side lower-limit conversion thermal power Pe at the time of the end of processing term tw is equal to or larger than the main notification heat- (For example, voice guidance of "change to big fire") (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 power Pt to the back side lower switching power Pe The fire power conversion voice information is not notified because it is less than the main notification thermal power change amount S described above.

The control operation of the back side automatic power adjustment control and the control operation after the processing end timing (tw) are the same as those of the first embodiment.

As described in detail above, according to this embodiment, even when the firepower of the stove burner 32 is increased when the pre-timing comes, the fire power of the stove burner 32 is switched The fire-fighting voice information due to the firepower change is not notified until the predetermined timing of the end of the process comes from the arrival of the pre-timing. Therefore, it is possible to prevent the fire-fighting voice information and the cooking timing voice information from being repeatedly notified in a short period of time. Furthermore, since only the dictionary timing voice information and the cooking timing voice information are notified when the advance timing comes, the user can reliably recognize the cooking timing voice information without confusing these voice information with the fire-fighting voice information. In addition, since only the dictionary-timing audio information is not notified until the cooking-timing audio information is notified, the user does not feel the troubles associated with the plurality of pieces of audio information, and the user can be prevented from becoming familiar with the notification. Thereby, it is possible to more reliably recognize the arrival of the cooking timing to the user. Since the pre-timing audio information is notified before the notification of the cooking timing audio information, it is possible to secure time such as the preparation of a cooking appliance for preparation of processing and the preparation of water to be processed.

Further, according to the present embodiment, when the pre-timing audio information is notified, since the thermal power of the stoker burner 32 is increased with a variation amount smaller than the main notification thermal power change amount until the process end timing comes, Even in the vicinity of the gas stove, the user feels a little surprised or embarrassed. Then, after the pre-timing comes, the food can be heated at a predetermined temperature until the end of the processing, so that the cooking can be smoothly advanced.

Further, according to the present embodiment, when the thermal power is increased to the main notification power change amount or more by the automatic power adjustment control, the fire power conversion voice information is notified so that the user can be reminded.

Therefore, according to the present embodiment, it is possible to provide a gas furnace that can be cooked smoothly in the automatic cooking mode in which a predetermined process is performed, has excellent usability of the user, and is excellent in safety.
