The structure of the device described below, the flowchart, and the like are not intended to be limited to only the specific description, but are merely illustrative examples. The drawings are used to explain the technical features that can be adopted by the present invention. In the following description, left and right, front and back, up and down indicated by arrows in the drawings are used.

-1st Embodiment-
The structure of the stove 1 will be described with reference to FIG. The stove 1 is a built-in stove. A top 3 is installed on the upper surface of the stove 1. On the top board 3, a right stove burner 4 is provided in front of the right hand, a left stove burner 6 in front of the left hand, and a back stove burner 5 on the far central side. At the center of each of the stove burners 4 to 6 is provided a sensor assembly 20 which abuts on the pan bottom to detect the temperature of the cooking pan. The sensor assembly 20 is vertically retractable and houses the thermistor 40 (see FIG. 2). In the vicinity of the stove burners 4 to 6, a thermocouple 50 (see FIG. 2) for detecting a misfire and an igniter 60 (see FIG. 2) for ignition are provided. At the rear of the top plate 3, an exhaust port 7 of a grill storage (not shown) installed in the stove 1 is provided. A rectangular display portion 22 is provided at a substantially central portion on the upper surface front side of the top 3. The display unit 22 is, for example, a liquid crystal. In addition to the operation screen (not shown) of the stove 1, the display unit 22 displays explanatory screens 101 to 104 (see FIGS. 8 to 11) and the like at the time of voice operation described later.

  A grill door 8 is provided substantially at the center of the front of the stove 1. The grill door 8 is movably supported on the front side, and opens and closes an opening on the front side of a grill storage (not shown) provided inside the stove 1. A grill burner (not shown) is provided in the grill storage. A thermocouple 50 and an igniter 60 are also provided in the vicinity of the grill burner. The grill burner may include, for example, a top burner and a bottom burner. In the area on the right side of the grille door 8, operation buttons 11 to 13 in a front view circular shape are provided side by side in a row in order from the right side to the left side. Also in the area on the left side of the grille door 8, the same circular operation button 14 is provided at the same height position as the operation buttons 11 to 13.

  The operation button 11 is pressed to ignite and extinguish the right stove burner 4, the operation button 12 to the back stove burner 5, the operation button 13 to the left stove burner 6, and the operation button 14 to the grill burner. The operation buttons 11 to 14 are substantially flush with the front of the stove 1 when the corresponding burners are extinguished (see FIG. 1). When pressed for ignition, the control circuit 70 described later executes an ignition process to the corresponding burner, and the operation buttons 11 to 14 are operated from the front of the stove 1 by a known push-push mechanism (not shown). It protrudes in a substantially cylindrical shape toward the front, and in this protruding state, the turning operation becomes possible. When the operation buttons 11 to 14 are turned, the control circuit 70 adjusts the amount of gas supplied to the corresponding burner so that the amount of gas corresponds to the amount of the turning operation.

  Inside the stove 1, four gas amount adjustment mechanisms 30 (see FIG. 2) are provided. The gas amount adjustment mechanism 30 adjusts the gas supply amount to the corresponding stove burners 4 to 6 and the grill burners. The gas amount adjustment mechanism 30 includes a valve mechanism 31 and a motor 32. The valve mechanism unit 31 includes, for example, various valves such as a needle valve and an electromagnetic valve that adjust the amount of gas flowing through the gas flow path. The motor 32 drives the valve of the valve mechanism 31 and the gas flow rate flowing through the gas flow path is adjusted. The drive of the motor 32 is controlled by the control circuit 70.

  When the operation buttons 11 to 14 are pushed to project forward, the control circuit 70 energizes the motor 32 of the gas amount adjustment mechanism 30. As a result, the valve mechanism unit 31 is driven and the gas flow path is opened, whereby the gas is supplied to the corresponding burner. Then, the control circuit 70 rotates the motor 32 in the forward and reverse directions according to the rotation direction and the rotation angle of the operation buttons 11 to 14 to adjust the opening degree of the valve in the valve mechanism section 31. Thereby, the power of the corresponding burner is adjusted by adjusting the amount of gas flowing through the gas flow path. When the operation buttons 11 to 14 are pushed into the stove 1 and accommodated, the control circuit 70 reversely rotates the motor 32. As a result, the valve of the valve mechanism 31 is driven in the reverse direction, and the gas flow path is closed to shut off the supply of gas to the corresponding burner.

  A power button 25 is provided immediately above the operation button 11. A hole 17 penetrating the panel on the front surface of the stove 1 is provided diagonally above the left of the operation button 14, and a microphone 76 is provided to the hole 17 so as to face the stove 1 from inside. The stove 1 of the present embodiment has a voice operation function. The voice operation function is a function that accepts the user's voice instruction by the microphone 76, identifies the content of the voice instruction by performing voice recognition, and enables the thermal operation of the burner targeted by the voice instruction. The voice instruction is an operation instruction such as a thermal power to the stove 1 by voice. The voice operation control process (see FIGS. 5 to 7) for executing the voice operation function will be described later. In the present embodiment, the right stove burner 4, the left stove burner 6, the back stove burner 5, and the grill burner may be referred to as the right stove 4, the left stove 6, the back stove 5, and the grill for convenience of description.

  The electrical configuration of the stove 1 will be described with reference to FIG. The stove 1 includes a control circuit 70. The control circuit 70 includes a CPU 71, a ROM 72, a RAM 73, a non-volatile memory 74, and the like. The CPU 71 centrally controls various operations of the stove 1. The ROM 72 stores various programs such as a voice operation control program. The voice operation control program executes a voice operation control process (see FIGS. 3 and 4) described later. The RAM 73 temporarily stores various information. The non-volatile memory 74 includes, in addition to various parameters for temperature control, acoustic model data for speech recognition, burner thermal power information, a cooking menu table 741 (see FIG. 3), a control information table 742 (see FIG. 4), etc. Store various data of The burner thermal power information is information in which the rotational angle of the output shaft of the motor 32 is associated with the burner thermal power. In the present embodiment, for example, small to large thermal powers are divided into ten stages of 1 to 10, and the rotation angle of the motor 32 is assigned to each stage. Thus, the CPU 71 can identify the corresponding burner thermal power based on the rotation angle of the output shaft of the motor 32. The cooking menu table 741 and the control information table 742 will be described later.

  The control circuit 70 includes a power supply circuit 81, a thermistor input circuit 82, a thermocouple input circuit 83, an igniter circuit 84, an operation panel 24, a motor control circuit 85, an audio input circuit 86, an audio output circuit 87, a buzzer circuit 88, display control Circuit 89, sensor 19 and the like are electrically connected to one another. When the power button 25 is pressed by the user, the power circuit 81 steps down an alternating current (for example, 100 V) supplied from the power supply 23 to a direct current (for example, 5 V) and rectifies it to supply power to various circuits. Therefore, the power of stove 1 is turned on. When the power button 25 is pressed again by the user, the power supply circuit 81 shuts off the power supply to the various circuits. Therefore, the power of stove 1 is turned off.

  The thermistor input circuit 82 inputs, to the control circuit 70, a detection signal from the thermistor 40 stored in the sensor assembly 20 provided in each burner. The thermocouple input circuit 83 inputs the detected value (a signal corresponding to the thermal electromotive force) from the thermocouple 50 to the control circuit 70. The igniter circuit 84 drives the igniter 60 of the corresponding burner based on the control signal from the CPU 71. The operation panel 24 is accommodated in the lower right portion of the front panel of the stove 1 and pulled out to the front side by pushing the portion. Operation panel 24 receives inputs such as timer setting by the user, selection of thermal power control according to the cooking menu, and the like, and inputs the input signal to control circuit 70. The motor control circuit 85 controls the drive of the motors 32 of the four gas amount adjustment mechanisms 30 based on the control signal from the CPU 71.

  The voice input circuit 86 converts an analog signal of the voice collected by the microphone 76 into a digital signal and inputs the digital signal to the control circuit 70. The audio output circuit 87 converts an audio digital signal into an analog signal based on a control signal from the CPU 71, and outputs the analog signal to the speaker 77. The buzzer circuit 88 drives the piezoelectric buzzer 78 based on a control signal of the CPU 71. The display control circuit 89 displays various screens on the display unit 22 based on a control signal from the CPU 71. The sensor 19 is provided on each of the operation buttons 11 to 14 to detect the rotation direction and the rotation angle of the operation buttons 11 to 14, and inputs the detection signal to the control circuit 70. Based on the detection signal from the sensor 19, the CPU 71 rotates the output shaft of the motor 32 to drive the valve mechanism 31 so as to correspond to the rotation direction and the rotation angle of the operation buttons 11-14. Thereby, the amount of gas flowing through the gas flow path is adjusted, and the power of the corresponding burner is adjusted.

  The gas amount adjustment mechanism 30 is provided with a position meter 35. The position meter 35 detects the rotation angle of the output shaft of the motor 32 and inputs the detection signal to the control circuit 70. The CPU 71 can recognize the rotation angle of the output shaft of the motor 32 based on the detection signal from the position meter 35. Therefore, the corresponding burner thermal power can be specified by referring to the burner thermal power information stored in the non-volatile memory 74.

  The cooking menu table 741 will be described with reference to FIG. The cooking menu table 741 is a data table that associates and stores the location of the heating source of the stove 1 and the type of cooking menu that can be performed at the location. The location of the heating source is the right stove, left stove, back stove, and grill. The cooking menu is a function in which the thermal power control of the burner is automatically performed in accordance with the type of cooking set in advance, and is set for each of four places in the stove 1. The cooking menus that can be performed by the right stove 4 and the left stove 6 are three types, simmered food, boiling water, and high-temperature stir-fry. There are three types of cooking menus that can be performed with the back stove 5: cooking, rice porridge and rice. There are three types of cooking menus available for grilling: grilled fish, bread / pizza, and baked goods. Although bread and pizza are different as the type of cooking, since the heating control in the grill is the same, they are handled as the same cooking menu in this embodiment.

  The control information table 742 will be described with reference to FIG. The control information table 742 is a data table that stores nine types of cooking and control information A to I corresponding to the types. The control information is information that defines the thermal power and heating time of the burner. Control information AC is control information of a cooking menu using the right stove 4 or the left stove 6. The control information D to F is control information of a cooking menu using the back stove 5. Control information GI is control information of a cooking menu using a grill. For example, the control information A of boiled food switches the thermal power to medium (for example, thermal power = 5), switches to small (for example, thermal power = 2) after the temperature sensor senses around 100 ° C., and switches to temperature control to keep at 100 ° C. When it starts to burn, it extinguishes automatically. The control information B for boiling water switches the thermal power to large (for example, thermal power = 8), switches to small (for example, thermal power = 2) after the temperature sensor senses around 100 ° C., and extinguishes after 3 minutes. The control information C of high-temperature stir switches the thermal power to large (for example, thermal power = 8), and switches to temperature control to keep at 250 ° C. after the temperature sensor detects around 250 ° C.

  The principle of the speech recognition function of the stove 1 will be briefly described. Speech recognition can use well-known speech recognition technology. For example, the “acoustic model data” stored in the non-volatile memory 74 may be matched with the input audio signal (waveform). "Acoustic model data" means a word dictionary of speech created based on average pronunciation data. For matching, for example, a theory called “HMM (Hidden Markov Model)” may be used. Matching is usually performed sequentially from the beginning of the word in units of 10 to 20 milliseconds. The speech recognition technology may be any other technology.

  The voice operation control process will be described with reference to FIGS. 5 to 7. When the user presses the power button 25 of the stove 1 and power is supplied from the power supply circuit 81 to the control circuit 70, the CPU 71 reads the voice operation control program from the ROM 72 and executes this processing.

  As shown in FIG. 5, the CPU 71 performs initial setting (S1). In the initial setting, the CPU 71 initializes setting values necessary for various processes. The CPU 71 determines whether any burner of the right stove 4, the left stove 6, the back stove 5, and the grill has been ignited (S2). The CPU 71 returns to S2 and stands by until any burner is ignited (S2: NO). When one of the burners is ignited (S2: YES), the CPU 71 identifies the burner which has been ignited based on the detection signal from the thermocouple 50 (S3), and the information of the burner being ignited is used as the ignition burner information. It is stored in the RAM 73. The CPU 71 outputs a voice of ignition guidance (S4). For example, when the right stove 4 is ignited, the speaker 77 outputs a voice "the right stove has been ignited." After that, even when another burner is ignited and a plurality of burners are ignited, the CPU 71 specifies the ignited burner based on the detection signal from the thermocouple 50, and stores it in the RAM 73 as ignition burner information. Do.

  The CPU 71 outputs the voice of the explanation of the method of starting the voice operation from the speaker 77 in order to notify the user of the method of starting the voice operation (S5). For example, the CPU 71 outputs, from the speaker 77, an audio of "Please speak" Start of voice operation "to start voice operation". The CPU 71 receives the start of the voice operation (S6). When the user performs a thermal operation or the like by voice instruction for the burner that has been ignited, the user may speak "start voice operation" to the stove 1. The voice of the user is collected by the microphone 76, converted from an analog signal of voice to a digital signal by the voice input circuit 86, and input to the control circuit 70. The CPU 71 performs speech recognition by matching the converted digital signal of the speech with the sound data of “voice operation start”.

  As a result of the speech recognition, the CPU 71 determines whether or not the speech instruction from the user is recognized as "the speech operation start" (S7). When not recognized as "voice operation start" or recognition is failed (S7: NO), the CPU 71 returns to S6, receives the voice instruction from the user again, and performs voice recognition. In addition, since the user does not utter "voice operation start" when not performing voice operation, even if another voice is collected from the microphone 76, the CPU 71 does not recognize "voice operation start" (S7: NO) ). Therefore, no voice operation is initiated.

  As a result of voice recognition, when the voice of the user collected by the microphone 76 is recognized as "voice operation start" (S7: YES), the CPU 71 starts the voice operation (S8) and the voice of the voice operation start guidance Output (S9). For example, the CPU 71 outputs, from the speaker 77, an audio of “start voice operation”. Thereby, the user can recognize that the voice operation has been started on the stove 1. The CPU 71 starts acceptance of the thermal power operation by the voice instruction (S10).

  The CPU 71 determines the currently acceptable thermal power operation based on the currently firing burner (S11). In the present embodiment, the thermal operation by voice instruction of the right stove 4, the back stove 5, the left stove 6, and the grill is "firepower large", "power fire", "heat power small", "cooking menu", There are five types of "fire extinguishing", but it may be changed for each burner. In the case of the thermal operation by voice instruction, for example, 8 for thermal power, 5 during thermal power, and 2 for small thermal power. For example, when the left stove 6 and the grille are ignited, the CPU 71 determines that "firepower large", "firepower middle", "heat power small", "cooking menu" and "fire extinguishing" as the currently accepted thermal power operations. Do. The CPU 71 stores, in the RAM 73, the information of the determined currently acceptable thermal power operation.

  The CPU 71 creates a guide voice for informing the user of choices of items that can be currently accepted by the stove 1, and outputs the same from the speaker 77 (S12). As a guide voice, for example, select a desired operation from among firepower large, firepower small, firepower small, cooking menu, fire extinguishing, end of voice operation, and output a voice instructing voice. Among the items that can be currently accepted include “completion of voice operation” in addition to the currently accepted thermal power operation, so it is effective when switching from voice operation to manual operation on the way etc.

  At the same time, the CPU 71 displays an explanation screen 101 (see FIG. 8) on the display unit 22 (S13). On the explanation screen 101, the same content as the outputted guide voice is displayed. As a result, the user can recognize the currently acceptable item in both voice and display, and thus can clearly recognize the word of the voice instruction. Especially during cooking, there are noises of various factors such as the sound of oil when frying food in a frying pan, the sound of a ventilation fan, and the sound when cooking utensils hit each other. There is a possibility that you may miss it, or you may forget it later. In the present embodiment, the guide voice is output from the speaker 77 and the display screen 22 is displayed on the display unit 22. Therefore, even if the user has missed the explanation output as the guide voice, the display 22 displays the guide voice. This can be confirmed on the explanation screen 101. Furthermore, since the words of the currently acceptable items can be clearly displayed on the explanation screen 101, the user can utter the correct words to the stove 1. Therefore, the possibility of misrecognition of voice instructions can be reduced. In addition, it is possible to prevent the user from giving an audio instruction at the wrong word.

  The user speaks to the stove 1 one of the thermal operations that he / she desires to perform on the burning burner from the thermal operations recognized by voice and display. The CPU 71 determines whether a voice instruction has been received from the user (S14). The CPU 71 returns to S14 and stands by until the voice instruction is received (S14: NO). When a voice instruction is received from the user (S14: YES), the CPU 71 performs voice recognition.

  The CPU 71 determines, as a result of the speech recognition, whether or not the received speech instruction matches the currently acceptable item (S15). If it does not match the currently acceptable item (S15: NO), the CPU 71 returns to S12 and outputs the guide voice from the speaker 77 again to notify the user of the correct thermal power operation etc. The screen 101 is displayed (S13). As a result, the user notices that the word of the firepower operation he has uttered is incorrect and can reconfirm items that can be currently received, so he can talk to the stove 1 with correct voice instructions.

  As a result of the speech recognition, when the received speech instruction matches the currently acceptable item (S15: YES), the CPU 71 determines whether the recognized speech instruction is "completion of speech operation" (S16). If the voice instruction is "end voice operation" (S16: YES), the CPU 71 terminates the voice operation and outputs a voice "voice operation has ended" from the speaker 77 (S18), It returns to the process of S5. Thereby, the user can recognize that the voice operation has ended.

  On the other hand, when the received voice instruction is not "voice operation end" (S16: NO), as shown in FIG. 6, the CPU 71 determines whether the received voice instruction is "cooking menu" (S21). For example, the user speaks “cooking menu” to the stove 1 when it is desired to automatically cook simmered food in the cooking menu using the left stove 6 being lit. When the voice instruction of the "cooking menu" is recognized (S21: YES), the CPU 71 extracts a place where the cooking menu can be executed based on the burner currently being ignited (S22). The place where the cooking menu can be performed is the place of the heating source where the burner is currently firing, and means the place where the cooking menu can be performed. Since the burner under ignition is the left stove 6 and the grill, the CPU 71 extracts the left stove 6 and the grill as a feasible place for the cooking menu. The CPU 71 temporarily stores the extracted information of these two places in the RAM 73.

  The CPU 71 creates a guide voice for informing the user of choices of items that can be currently accepted by the stove 1, and outputs it from the speaker 77 (S23). The currently available items include two places stored in the RAM 73. As a guide voice, for example, select one of the cooking areas in the cooking menu from the left stove and grill, and give voice instructions. If you want to extinguish the fire, extinguish the fire, if you want to end the voice operation Output an audio message saying "Operation complete and voice instruction". In addition, since "fire extinguishing" and "end of voice operation" are included in the choices of acceptable items described in the guide voice, for example, when you want to extinguish the burner during cooking, or switch from voice operation to manual operation It is effective when you want to At the same time, the CPU 71 displays an explanation screen 102 (see FIG. 9) on the display unit 22 (S24). On the explanation screen 102, the same content as the outputted guide voice is displayed. As a result, the user can recognize the choices of items that can be currently accepted by both voice and display, and thus can clearly recognize words of voice instructions.

  From the two places recognized by voice and display, the user chooses a place to execute the cooking menu previously specified by the voice instruction and speaks to the stove 1. The CPU 71 determines whether a voice instruction has been received from the user (S25). The CPU 71 returns to S25 and stands by until a voice instruction is received (S25: NO). If a voice instruction has been received from the user (S25: YES), the CPU 71 performs voice recognition. As a result of the speech recognition, the CPU 71 determines whether or not the received speech instruction matches the currently acceptable item (S26). If it does not match the currently acceptable item (S26: NO), the CPU 71 returns to S23 and outputs the guide voice from the speaker 77 again to inform the user of the correct place etc. again.

  As a result of the speech recognition, when the received speech instruction matches the currently acceptable item (S26: YES), the CPU 71 determines whether the recognized speech instruction is "completion of speech operation" (S27). If the voice instruction is "end voice operation" (S27: YES), the CPU 71 ends the voice operation and proceeds to S18 in FIG. 5, and the speaker 77 "voice operation finished." Output from The CPU 71 returns to S5 to repeat the above processing.

  As described above, since the user wants to cook boiled food on the left stove 6, the voice instruction for place specification is "left stove". The user speaks to the stove 1 "left stove". When the CPU 71 recognizes the voice instruction from the user as the "left stove" (S26: YES, S27: NO), the CPU 71 temporarily stores information of the recognized location in the RAM 73 (S28). The CPU 71 extracts a cooking menu executable at the recognized place from the cooking menu table 741 (see FIG. 3) stored in the non-volatile memory 74 (S29). Since the place recognized is the "left stove", viable cooking menus are three types: boiled, boiling, and high-temperature stir-frying.

  The CPU 71 creates a guide voice for informing the user of choices of items that can be currently accepted by the stove 1, and outputs it from the speaker 77 (S30). The items that can be currently received include the three cooking menus extracted in the process of S29. As a guide voice, for example, select one of the cooking menu performed on the left stove from simmered food, boiling water, high-temperature stir-fry, and give a voice instruction. In case of voice operation end and voice instruction please output the voice. At the same time, the CPU 71 displays an explanatory screen 103 (see FIG. 10) on the display unit 22 (S31). On the explanation screen 103, the same content as the outputted guide voice is displayed. As a result, the user can recognize the choices of items that can be currently accepted by both voice and display, and thus can clearly recognize words of voice instructions.

  The user speaks to the stove 1 by selecting "boiled food" from the three cooking menus recognized by voice and display. The CPU 71 determines whether a voice instruction has been received from the user (S32). If the voice instruction has not been received (S32: NO), the CPU 71 returns to S32 and stands by. When a voice instruction is received from the user (S32: YES), the CPU 71 performs voice recognition.

  As a result of the speech recognition, the CPU 71 determines whether or not the received speech instruction matches the currently acceptable item (S33). If it does not match the currently acceptable item (S33: NO), the CPU 71 returns to S30 and outputs the guide voice from the speaker 77 again to notify the user of the correct place. As a result, the user can, for example, notice that the word of the cooking menu uttered is incorrect and can reconfirm items that can be currently received, so the user can talk to the stove 1 with correct voice instructions.

  As a result of the speech recognition, when the received speech instruction matches the currently acceptable item (S26: YES), the CPU 71 determines whether the recognized speech instruction is "completion of speech operation" (S27). If the voice instruction is "end voice operation" (S27: YES), the CPU 71 ends the voice operation and proceeds to S18 in FIG. 5, and the speaker 77 "voice operation finished." Output from The CPU 71 returns to S5 and repeats the above process.

  When the voice instruction from the user is recognized as "boiled food" (S33: YES, S34: NO), the CPU 71 temporarily stores the recognized cooking menu in the RAM 73 (S35). The CPU 71 creates, for example, an execution operation voice of "automatic cooking of boiled food on the left stove", and outputs it from the speaker 77 (S36). Thereby, the user can recognize from this that automatic cooking of boiled food is started on the left stove 6. Then, the CPU 71 reads the control information A of "boiled food" from the control information table 742 (see FIG. 4) stored in the non-volatile memory 74 (S37), and the cooking menu specified by the left stove 6 received earlier. The "boiled food" which is is executed (S38). In the thermal power control of boiled food, switch the thermal power of the left stove 6 to medium (thermal power = 5) based on the control information A, switch the thermistor 40 to small (thermal power = 2) after sensing around 100 ° C and keep at 100 ° C Switch to temperature control, and start burning automatically when it starts to burn. During the temperature control, the user can cook while checking the heating condition of the food while, for example, stirring the food in the cooking pot.

  The CPU 71 returns to S11 of FIG. 5, and determines the currently acceptable thermal power operation again based on the burner currently being ignited. The CPU 71 outputs a guide voice for designating one of the currently accepted thermal power operations from the speaker 77 (S12), and displays the explanation screen 101 (S13). The CPU 71 returns to S13 and stands by until a voice instruction from the user is received (S13: NO).

  Here, when the user wants to end the cooking menu of the simmered food being performed on the left stove 6, the user may extinguish the left stove 6 with a voice instruction. For example, as shown in FIG. 12, in the current state A, the left stove 6 and the grille are in an ignited state. In the left stove 6, the cooking menu of the boiled food is under execution, and is controlled by the middle power (power = 5). In the grille, it is adjusted to large thermal power (thermal power = 8). The user talks to the stove 1 "extinguishing fire". When the CPU 71 receives a voice instruction from the user (S14: YES) and recognizes it as "fire extinguishing" (S15: YES, S16: NO, S21: NO in Fig. 6), "fire extinguishing" as fire power operation information in the RAM 73 Remember.

  As shown in FIG. 7, the CPU 71 determines whether the number of burners currently being ignited is one or not (S51). In the state A, since two burners (the left stove 6 and the grill) are being ignited (S51: NO), which location of the two firing burners is the target of the received thermal power operation is targeted It is unknown. Therefore, the CPU 71 needs to specify the location of the burner which is the target of the thermal power operation by voice instruction. In particular, the CPU 71 continues to execute the following control in order to promptly respond to the thermal power operation that needs to be performed immediately, such as "fire extinguishing".

  The CPU 71 determines the rotation angle of the motor 32 of the gas amount adjustment mechanism 30 corresponding to the two firing burners, refers to the burner thermal power information stored in the non-volatile memory 74, and determines the burners currently firing and the respective burners. The thermal power is specified and temporarily stored in the RAM 73 as former thermal power information (S52). The power of the left stove 6 is 5, and that of the grill is 8. Then, the CPU 71 drives the motor 32 of the gas amount adjustment mechanism 30 of the left stove 6 and the grill, which are being ignited, and drives the valve mechanism section 31 to make the two ignitions in progress as in the state B. The left stove 6 and the burner firepower of the grill are temporarily changed to all 1 once to minimize the fire power (S53). As a result, since the thermal power is weakened for a while until the location of the target burner of the thermal power operation is specified, it is possible to sufficiently cope with the case where it is necessary to immediately carry out such as weakening the thermal power.

  Subsequently, the CPU 71 extracts a place where the thermal power operation received earlier is acceptable, based on the burner currently being ignited (S54). The places where it is possible to receive the fire operation are the left stove 6 and the grill which are being ignited. Therefore, the CPU 71 creates a guide voice for informing the user of choices of items that can be accepted by the stove 1 and causes the speaker 77 to output the voice from the speaker 77 (S55). As a guide voice, for example, a voice "Please select one from left stove, grill, fire extinguishing, end of voice operation, and give a voice instruction" is output. At the same time, the CPU 71 displays an explanation screen 104 (see FIG. 11) on the display unit 22 (S56). On the explanation screen 104, the same content as the output guide voice is displayed.

  The user speaks the stove 1 with the location of the burner for performing the fire operation specified by the voice instruction from the locations notified by the voice and the display. The user speaks with the "left stove" toward the stove 1. The CPU 71 determines whether a voice instruction has been received from the user (S57). If the voice instruction has not been received (S57: NO), the CPU 71 returns to S57 and stands by. If a voice instruction has been received from the user (S57: YES), the CPU 71 determines whether the received voice instruction matches the word of an acceptable item (S58). If the word does not match the word of the acceptable place (S58: NO), the CPU 71 returns to S55 and outputs the guide voice from the speaker 77 again to notify the user of the correct place etc. again.

  As a result of the speech recognition, when the received voice instruction matches the acceptable item (S58: YES), the CPU 71 determines whether the recognized voice instruction is "end of voice operation" (S59). If the voice instruction is "voice operation end" (S59: YES), the CPU 71 proceeds to S18 in FIG. 5 and terminates the voice operation and simultaneously outputs the voice "voice operation has been completed" to the speaker 77. Output from The CPU 71 returns to S5 to repeat the above processing.

  On the other hand, in the state B, when the voice instruction from the user is recognized as the "left stove" (S58: YES, S59: NO), the CPU 71 determines the left stove 6 as the target burner (S60). A target burner means the burner of the target which performs the thermal power operation received previously. Based on the thermal power operation information stored in the RAM 73, the thermal power operation received earlier is "extinguishing fire". Therefore, the CPU 71 creates an execution operation sound of the content for extinguishing the left stove 6, and outputs it from the speaker 77 (S61). The CPU 71 outputs, for example, an execution operation sound such as "extinguish the left stove". Thereby, the user can recognize that the left stove 6 is extinguished.

  After outputting the execution operation voice, the CPU 71 executes "fire extinguishing", which is the thermal power operation received earlier, on the left stove 6, which is the target burner (S62). Thus, the cooking menu which has been executed is ended. Furthermore, at the same time or slightly after this, the CPU 71 restores burner thermal power other than the target burner to original thermal power with reference to the original thermal power information stored in the RAM 73 (S63). Burners other than the target burner are grills. As a result, as in state C shown in FIG. 12, the left stove 6 is extinguished, and the power of the grill can be returned from 1 to 8 which is the original power. Thereby, even if a plurality of burners are in an ignition state, only a specific burner can be extinguished correctly and safely by voice instruction of the user. Further, in the present embodiment, since the execution operation voice is output before the thermal power operation is performed, the user can recognize in advance that the thermal power is to be switched from this, so that it is possible to prevent the thermal power from being switched unexpectedly.

  Next, the CPU 71 determines whether there is a burner being ignited (S64). If there is a burner being ignited (S64: YES), the CPU 71 returns to S11 of FIG. 5 and repeats the above process. On the other hand, when all the burners of the stove 1 are extinguished (S64: NO), the CPU 71 ends the voice operation, and outputs the voice of the end of the voice operation from the speaker 77 (S65). The CPU 71 outputs, for example, a voice “finish the voice operation.” The CPU 71 returns to S2 in FIG. 3, determines again whether the burner has been ignited, and repeats the above process.

  In addition, when the voice instruction | indication of a thermal-power operation is received and recognized previously by S14 of FIG. 5 (S15: NO, S16: NO, S21: NO of FIG. 6) and the burner under ignition is one (FIG. 7) S51: YES), since the target burner is one burner currently being ignited, there is no need to specify the location as in the case of plural burners being ignited. Therefore, if only the grill is ignited, the CPU 71 creates an execution operation sound of the content for extinguishing the grill and outputs it from the speaker 77 (S67). The CPU 71 outputs, for example, an execution operation sound such as "extinguish the grill." After outputting the execution operation voice, the CPU 71 executes fire extinguishing, which is a thermal power operation, on the grille being ignited (S68). The CPU 71 advances the process to S64 and repeats the above process.

  As described above, the stove 1 of the first embodiment receives voice instructions from the user, and can individually control the operation of the burners, which are a plurality of heating sources, based on the contents of recognition of the received voice instructions. is there. In the stove 1, execution of a desired cooking menu can be received by voice instruction at a desired place among a plurality of heating sources. The CPU 71 of the stove 1 first receives a place for executing the cooking menu among the plurality of heating sources by voice instruction. The CPU 71 extracts, from the cooking menu table 741 stored in the non-volatile memory 74, a cooking menu executable at the place of the heating source received earlier. The CPU 71 notifies the selected cooking menu option by voice or display. After the notification, as a result of recognizing the voice instruction received from the user, when it matches with any of the options of the notified cooking menu, the matched cooking menu is executed at the place where it is received first. As described above, since the user designates a desired cooking menu from the informed options by voice instruction, it is possible to reduce the possibility of the user inputting a different voice instruction. Therefore, the stove can be run smoothly where the desired cooking menu was first received.

-Second embodiment-
The second embodiment is a modification of the first embodiment, and only a part of the voice operation control process executed by the CPU 71 is different. Therefore, in the present embodiment, parts different from the first embodiment will be mainly described, and the description of the common parts will be simplified or omitted.

  When the cooking menu is received by voice instruction, in the voice operation control process of the first embodiment, the location of the heating source for executing the cooking menu is first received, and the option of the cooking menu executable at the accepted location is voiced or displayed Informing by the user can prompt the user for an accurate voice instruction. On the other hand, in the voice operation control process of the second embodiment, the type of the cooking menu is received first, and the choice of the location of the heat source that can execute the received cooking menu is notified by voice or display. Can prompt the person to give accurate voice instructions.

  As shown in FIG. 13, the voice operation control process of the second embodiment includes the process of S101 between S21 and S23, and the processes of S102 and S103 between S27 and S30, and between S34 and SS36. The processing of S104 is provided, and the processing of S105 is provided after the processing of S37. The rest is the same as the first embodiment.

  For example, it is assumed that the cooking menu is performed using the left stove 6 while the left stove 6 and the grill are in the process of being ignited. When the "cooking menu" is received by voice instruction from the user (S21: YES), the CPU 71 determines the acceptable cooking menu at the location of the burner under ignition based on the ignition burner information stored in the RAM 73 (S101) ). Since the burner under ignition is the left stove 6 and the grill, the CPU 71 extracts the cooking menu executable on the left stove 6 or the grill based on the cooking menu table 741 stored in the non-volatile memory 74. The cooking menus that can be performed on the left stove 6 or the grill are six types: boiled, boiling, hot-fry, grilled fish, bread / pizza, and baked confectionery.

  In order to notify the user of the currently executable cooking menu, the CPU 71 creates a guide voice of an acceptable item including the extracted cooking menu and outputs it from the speaker 55 (S23). The CPU 71 displays an explanatory screen in addition to the guide voice (S24). The user selects one cooking menu from the informed cooking menu and talks to the stove 1.

  When the CPU 71 recognizes the type of the cooking menu by voice instruction (S25: YES, S26: YES, S27: NO), the CPU 71 temporarily stores the cooking menu recognized in the RAM 73 (S102). The CPU 71 extracts a place where the cooking menu stored in the RAM 73 can be executed, from the ignition burner information stored in the RAM 73 (S103). The CPU 71 creates a guide voice of an acceptable item including the extracted place and outputs it from the speaker 55 in order to notify the user of the place where the cooking menu received by the voice instruction is executed from the burners being ignited. (S30). The CPU 71 displays an explanatory screen in addition to the guide voice (S31). For example, when a grilled fish is accepted as a cooking menu, only grills can cook grilled fish, and therefore the CPU 71 reports "grill" as voice and display as a place where grilled fish can be cooked. The user speaks "grill" to the stove 1 based on the notified location.

  When the CPU 71 recognizes the place to execute the cooking menu by voice instruction (S32: YES, S33: YES, S34: NO), the CPU 71 temporarily stores the recognized place (for example, grill) in the RAM 73 (S104). Then, the CPU 71 creates, for example, an execution operation voice of "automatic grilled fish is cooked on the grill", and outputs it from the speaker 77 (S36). Thereby, the user can recognize from this that automatic cooking of grilled fish is started on the grill. Next, the CPU 71 reads the control information G of "baked fish" from the control information table 742 stored in the non-volatile memory 74 (S37), and executes the specified cooking menu "baked fish" with the recognized grille (S105) .

  As described above, also in the stove 1 of the second embodiment, by executing the voice operation control process, as in the first embodiment, the desired cooking menu can be provided at a desired place among a plurality of heating sources. Execution can be accepted by voice instruction. The CPU 71 of the stove 1 first receives the type of cooking menu by voice instruction. The CPU 71 extracts, from the cooking menu table 741 stored in the non-volatile memory 74, the location of the heating source that can execute the cooking menu received earlier. The CPU 71 notifies of the option of the extracted heat source location by voice or display. After the notification, as a result of recognizing the voice instruction received from the user, when it matches with the option of the location of the notified heat source, the cooking menu received earlier is executed at the location of the matched heat source. As described above, the user designates the desired cooking menu from the informed options by voice instruction, and then designates the position of the desired heating source from the options informed by the stove 1 by audio instruction. Therefore, the stove 1 can reduce the possibility that a user may input different voice instructions. Therefore, the stove 1 can smoothly execute the cooking menu received earlier at the desired place.
