Hereinafter, embodiments of the present invention will be described. Unless otherwise specified, the structure, flowchart, and the like of the device described below are not intended to be limited thereto, but are merely explanatory examples. The drawings are used to illustrate the technical features that can be adopted by the present invention. In the following description, the left and right, front and back, and top and bottom indicated by arrows in the figure are used.

The structure of the stove 1 will be described with reference to FIG. The stove 1 is a built-in stove. A top plate 3 is installed on the upper surface of the stove 1. In the top plate 3, a right stove burner 4 is provided on the front right side, a left stove burner 6 is provided on the front left side, and a back stove burner 5 is provided on the back side of the center. At the center of each stove burner 4 to 6, a sensor assembly 20 that comes into contact with the bottom of the pot and detects the temperature of the cooking pot is provided. The sensor assembly 20 is provided so as to be able to move in and out in the vertical direction, and houses the thermistor 40 (see FIG. 2). A thermocouple 50 (see FIG. 2) for detecting a misfire and an igniter 60 (see FIG. 2) for igniting are provided in the vicinity of the stoves 4 to 6. An exhaust port 7 of a grill storage (not shown) installed in the stove 1 is provided at the rear portion of the top plate 3. A rectangular display portion 22 is provided at a substantially central portion on the front side of the upper surface of the top plate 3. The display unit 22 is, for example, a liquid crystal display. The display unit 22 displays a setting screen (not shown) of the stove 1, explanatory screens 101 and 102 (see FIGS. 8 and 9) at the time of voice operation, which will be described later.

A grill door 8 is provided at substantially the center of the front surface of the stove 1. The grill door 8 is movably supported toward the front side, and opens and closes an opening on the front side of the grill storage (not shown) provided inside the stove 1. A grill burner (not shown) is provided in the grill chamber. A thermocouple 50 and an igniter 60 are also provided in the vicinity of the grill burner. In the area on the right side of the grill door 8, operation buttons 11 to 13 having a circular front view are provided in a horizontal row in order from the right side to the left side. Also in the area on the left side of the grill door 8, the operation buttons 14 having the same circular shape are provided at the same height positions as the operation buttons 11 to 13.

The operation button 11 is the right stove burner 4, the operation button 12 is the back stove burner 5, the operation button 13 is the left stove burner 6, and the operation button 14 is pressed to ignite and extinguish the grill burner. The operation buttons 11 to 14 are substantially flush with the front surface of the stove 1 when the corresponding burner is extinguished (see FIG. 1). When pressed for ignition, the control circuit 70, which will be described later, executes the ignition process for the corresponding burner, and the known push-push mechanism (not shown) allows the operation buttons 11 to 14 to be pressed from the front surface of the stove 1. It protrudes forward in a substantially columnar shape, and the rotation operation is possible in the protruding state. When the operation buttons 11 to 14 are rotated, the control circuit 70 adjusts the gas supply amount to the corresponding burner so that the gas amount corresponds to the rotation operation amount.

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

When the operation buttons 11 to 14 are pushed in and projected toward the front, the control circuit 70 energizes the motor 32 of the gas amount adjusting mechanism 30. As a result, the valve mechanism portion 31 is driven and the gas flow path is opened, so that 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, and adjusts the opening degree of the valve in the valve mechanism unit 31. As a result, the amount of gas flowing through the gas flow path is adjusted, so that the thermal power of the corresponding burner is adjusted. Further, when the operation buttons 11 to 14 are pushed into the stove 1 to be accommodated, the control circuit 70 rotates the motor 32 in the reverse direction. As a result, the valve of the valve mechanism unit 31 is driven in the opposite direction, and the gas flow path is closed, so that the supply of gas to the corresponding burner is cut off.

A power button 25 is provided directly above the operation button 11. A hole 17 penetrating the panel on the front surface of the stove 1 is provided obliquely to the upper left of the operation button 14, and the microphone 76 is provided so as to face the hole 17 from the inside of the stove 1. The stove 1 of the present embodiment has a voice operation function. The voice operation function is a function that receives a user's voice instruction with the microphone 76, identifies the content of the voice instruction by performing voice recognition, and enables the thermal power operation of the target burner. The voice instruction is an operation instruction such as thermal power given to the stove 1 by voice. The voice operation control process (FIGS. 3 to 6) for realizing the voice operation function will be described later.

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, and also includes a timer, an I / O interface, and the like (not shown). The CPU 71 controls various operations of the stove 1 in an integrated manner. The ROM 72 stores various programs such as a voice operation control program. The voice operation control program executes the voice operation control process (see FIGS. 3 and 4) described later. The RAM 73 temporarily stores various types of information. The non-volatile memory 74 stores various data such as acoustic model data for voice recognition and burner thermal power information in addition to various parameters for temperature control control. The burner thermal power information is information in which the rotation angle of the output shaft of the motor 32 is associated with the burner thermal power. In the present embodiment, the thermal power from small to large is divided into 10 stages of 1 to 10, and the rotation angle of the motor 32 is assigned to each stage. Thereby, the CPU 71 can specify the corresponding burner thermal power based on the rotation angle of the output shaft of the motor 32.

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, a voice input circuit 86, a voice output circuit 87, a buzzer circuit 88, and display control. The circuit 89, the sensor 19, and the like are electrically connected to each other. When the power button 25 is pressed by the user, the power supply circuit 81 steps down the alternating current (for example, 100V) supplied from the power supply 23 to a direct current (for example, 5V), rectifies it, and supplies electric power to various circuits. Therefore, the power of the stove 1 is turned on. When the power button 25 is pressed again by the user, the power supply circuit 81 cuts off the power supply to various circuits. Therefore, the power of the stove 1 is turned off.

The thermistor input circuit 82 inputs a detection signal from the thermistor 40 stored in the sensor assembly 20 provided in each burner to the control circuit 70. The thermocouple input circuit 83 inputs the detection value (signal corresponding to the thermoelectromotive 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 housed in a lower right portion of the front panel of the stove 1, and is pulled out toward the front side by pushing the portion. The operation panel 24 receives inputs such as timer setting by the user and selection of thermal power control according to the cooking menu, and inputs the input signal to the control circuit 70. The motor control circuit 85 controls the driving of the motors 32 of the four gas amount adjusting mechanisms 30 based on the control signals from the CPU 71.

The audio input circuit 86 converts the analog signal of the audio collected by the microphone 76 into a digital signal and inputs it to the control circuit 70. The audio output circuit 87 converts an audio digital signal into an analog signal based on the control signal from the CPU 71, and outputs the audio to the speaker 77. The buzzer circuit 88 drives the piezoelectric buzzer 78 based on the control signal of the CPU 71. The display control circuit 89 displays various screens on the display unit 22 based on the control signal from the CPU 71. The sensors 19 are provided on the operation buttons 11 to 14 respectively, detect the rotation direction and the rotation angle of the operation buttons 11 to 14, and input 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 so as to correspond to the rotation direction and the rotation angle of the operation buttons 11 to 14, and drives the valve mechanism unit 31. As a result, the amount of gas flowing through the gas flow path is adjusted, and the thermal power of the corresponding burner is adjusted.

The gas amount adjusting 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. Since 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, the corresponding burner thermal power can be specified by referring to the burner thermal power information stored in the non-volatile memory 74.

The principle of the voice recognition function of the stove 1 will be briefly described. For voice recognition, a well-known voice recognition technique can be used. For example, it is preferable to perform matching (collation) between the "acoustic model data" stored in the non-volatile memory 74 and the input audio signal (waveform). "Acoustic model data" means a speech word dictionary created based on average pronunciation data. For matching, for example, a theory called "HMM (Hidden Markov Model)" may be used. Matching is usually done in units of 10 to 20 milliseconds, starting from the beginning of the word. The voice recognition technology may be other technology.

The voice operation control process will be described with reference to FIGS. 3 to 9. When the user presses the power button 25 of the stove 1 and power is supplied from the power circuit 81 to the control circuit 70, the CPU 71 reads the voice operation control program from the ROM 72 and executes this process. In the present embodiment, for convenience of the following description, the right stove burner 4, the left stove burner 6, the back stove burner 5, and the grill burner are referred to as a right stove 4, a left stove 6, a back stove 5, and a grill, respectively.

As shown in FIG. 3, the CPU 71 makes initial settings (S1). In the initial setting, the CPU 71 initializes the set values required for various processes. Next, the CPU 71 determines whether or not any of the burners of the right stove 4, the left stove 6, the back stove 5, and the grill is ignited (S2). The CPU 71 returns to S2 and waits until any of the burners is ignited (S2: NO). When any of the burners is ignited (S2: YES), the CPU 71 identifies the ignited burner based on the detection signal from the thermocouple 50 (S3), and uses the information of the igniting burner as the ignition burner information. Store in RAM 73.

Next, the CPU 71 outputs the sound of the ignition guidance (S4). For example, when the right stove 4 is ignited, the voice "The right stove has been ignited" is output from the speaker 77. As a result, the user can recognize that the right stove 4 has been ignited. After that, even when another burner is ignited and a plurality of burners are in the ignition state, the CPU 71 identifies the ignited burner based on the detection signal from the thermocouple 50 and stores it in the RAM 73 as ignition burner information. do.

Next, the CPU 71 outputs a voice explaining the start of the voice operation from the speaker 77 in order to inform the user of the method of starting the voice operation (S5). For example, the CPU 71 outputs a voice message "To start the voice operation, say" Start voice operation "" from the speaker 77. The CPU 71 accepts the start of voice operation (S6). When the user performs a thermal power operation or the like by voice instruction for the ignited burner, he / she speaks to the stove 1 "start voice operation". The user's voice is collected by the microphone 76, converted from the analog signal of the voice to the digital signal by the voice input circuit 86, and input to the control circuit 70. The CPU 71 performs voice recognition processing by matching the converted digital signal of voice with the acoustic data of "start of voice operation".

As a result of the voice recognition process, the CPU 71 determines whether or not the user's voice instruction is recognized as "start of voice operation" (S7). For example, if it is not recognized as "start of voice operation" or recognition fails (S7: NO), the CPU 71 returns to S6, receives a voice instruction from the user again, and performs voice recognition processing. If no voice operation is performed, the user does not say "start voice operation", so even if another voice is collected from the microphone 76, the CPU 71 does not recognize "start voice operation" (S7: NO). ). Therefore, the voice operation is not started.

As a result of the voice recognition process, when the user's voice 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. Is output (S9). The CPU 71 outputs, for example, a voice "Start voice operation" from the speaker 77. As a result, the user can recognize that the voice operation has been started on the stove 1. The CPU 71 starts accepting the thermal power operation by voice instruction (S10).

Next, the CPU 71 determines the currently acceptable thermal power operation based on the burner currently being ignited (S11). In the present embodiment, in any of the burners of the right stove 4, the back stove 5, the left stove 6, and the grill, the thermal power operation is "high thermal power", "medium thermal power", "small thermal power", and "fire extinguishing". There are four types, but they may be changed for each burner. Since the burners currently being ignited are the back stove 5, the left stove 6, and the grill, the currently acceptable thermal power operations are determined to be "high thermal power", "medium thermal power", "small thermal power", and "fire extinguishing". The CPU 71 stores the determined information on the currently acceptable thermal power operation in the RAM 73. Next, the CPU 71 outputs a guide sound from the speaker 77 to inform the user of the options of the items currently accepted by the stove 1 (S12). As a guide voice, for example, a voice saying "Please select one from high firepower, medium firepower, low firepower, fire extinguishing, and end of voice operation and give a voice instruction" is output. In addition to the currently acceptable thermal power operation stored in the RAM 73, the currently acceptable items include "end of voice operation", which is effective when you want to switch from voice operation to manual operation in the middle. be.

At the same time, the CPU 71 displays the explanation screen 101 (see FIG. 8) on the display unit 22 (S13). On the explanation screen 101, the items of the control command that can be currently executed are displayed in a list with the same contents as the output guide voice. As a result, the user can recognize the item of the control command that can be currently executed by both voice and display, so that the word of the voice instruction can be clearly recognized. Therefore, the stove 1 can prevent the user from issuing a voice instruction with an erroneous word.

Also, during cooking, there are noises of various factors such as the sound of oil when frying ingredients in a frying pan, the sound of a ventilation fan, the sound of hitting kitchen utensils, etc., so only the guide sound from the speaker 77 Then, there is a possibility that you may miss it, or even if you hear it, you may forget it later. However, in the present embodiment, the guide sound is output from the speaker 77, and the explanation screen 101 is displayed on the display unit 22. As a result, even if the explanation output by the guide voice is overlooked, it can be confirmed on the explanation screen 101 displayed on the display unit 22. Further, since the words of the thermal power operation that can be performed at present can be clearly displayed on the explanation screen 101, the user can speak with accurate words to the stove 1. Therefore, the possibility of erroneous recognition can be reduced.

Then, the user selects one thermal power operation to be performed on the burning burner from the thermal power operations notified by voice and display, and speaks to the stove 1. The CPU 71 determines whether or not the voice instruction has been received from the user (S14). When the voice instruction is not accepted (S14: NO), the CPU 71 initializes the timer t to 0 and turns it on, and determines whether or not the state of not accepting the voice instruction continues for 5 minutes (S19). The value of the timer t is stored in, for example, the RAM 73. If the state of not accepting the voice instruction has not continued for 5 minutes (S19: NO), the CPU 71 returns to S14 and waits until the voice instruction is received.

When the voice instruction is received from the user (S14: YES) before the state of not accepting the voice instruction continues for 5 minutes, the CPU 71 stores the received digital data of the voice instruction and the non-volatile memory 74. Of the acoustic data, the words of the currently acceptable items are matched with the acoustic data, and the above-mentioned voice recognition is performed. As a result, the CPU 71 determines whether or not the item matches the currently acceptable item (S15). If the user speaks the wrong word, it does not match the currently accepted words for thermal power operation (S15: NO), so recognition fails. Therefore, in order to notify the user of the correct thermal power operation again, the CPU 71 returns to S12 and outputs the guide sound again from the speaker 77. As a result, the user notices that the words of the thermal power operation spoken by himself / herself are incorrect, and can reconfirm the items currently accepted, so that he / she can speak to the stove 1 with the correct voice instruction.

Then, as a result of voice recognition, when the voice instruction from the user matches the currently acceptable item (S15: YES), the CPU 71 determines whether or not the recognized voice instruction is "end of voice operation". (S16). When the voice instruction is "voice operation end" (S16: YES), the CPU 71 ends the voice operation and outputs a voice "voice operation is finished" from the speaker 77 (S18). Return to the process of S5. As a result, the user can recognize that the voice operation has been completed.

Here, for example, the state A shown in FIG. 7 is assumed. In the state A, the left stove 6, the back stove 5, and the grill are all ignited, and the right stove 4 is extinguished. In such a state A, when it is desired to extinguish only the grill being ignited, the user speaks to the stove 1 "fire extinguishing" because "fire extinguishing" is a currently acceptable thermal power operation. When the voice instruction is "fire extinguishing" (S15: YES, S16: NO), the CPU 71 temporarily stores the recognized thermal power operation "fire extinguishing" in the RAM 73 as thermal power operation information (S17). Subsequently, as shown in FIG. 4, the CPU 71 determines whether or not there is only one burner currently igniting (S20). Here, in the state A, since the three burners (left stove 6, back stove 5, grill) are igniting (S20: NO), the previously accepted thermal power operation (“fire extinguishing” in this embodiment) is It is unclear which of the three igniting burners is targeted. Therefore, following the thermal power operation, it is necessary to specify the location of the target burner for the thermal power operation by voice instruction. In particular, the CPU 71 continues to execute the following controls in order to deal with a thermal power operation that needs to be performed immediately, such as "fire extinguishing".

First, the CPU 71 obtains the rotation angle of the motor 32 of the gas amount adjusting mechanism 30 corresponding to the three igniting burners, refers to the burner thermal power information stored in the non-volatile memory, and refers to the burner currently igniting and each of them. Identify the burner firepower (S21). The CPU 71 temporarily stores the specified ignition burner and the information on each burner thermal power in the RAM 73 as the original thermal power information (S22). In the state A, the igniting burners are the left stove 6, the back stove 5, and the grill, the left stove 6 has a firepower of 9, the back stove 5 has a firepower of 3, and the grill has a firepower of 8. Next, the CPU 71 drives the motors 32 of the gas amount adjusting mechanisms 30 of the burners during ignition, and drives the valve mechanism portion 31, thereby temporarily changing all the three ignition burner thermal powers to low thermal powers. (S23). Therefore, as shown in the state B shown in FIG. 7, the thermal powers of the left stove 6, the back stove 5, and the grill are all set to 1 once. As a result, the thermal power is weakened for the time being until the location of the target burner for the thermal power operation is specified, so that it is possible to sufficiently cope with the case where it is necessary to immediately reduce the thermal power.

Subsequently, the CPU 71 starts accepting the location designation by voice instruction (S24). The CPU 71 determines a currently acceptable location based on the currently ignited burner (S25). Since the currently acceptable locations are the left stove 6, the back stove 5, and the grill during ignition, the CPU 71 temporarily stores these determined locations in the RAM 73. Then, in order to make the user specify the location of the thermal power operation by voice instruction, the CPU 71 creates guide voice data for informing the user of the options of the items currently accepted by the stove 1, and outputs the guide voice data from the speaker 77. (S26). As described above, in the state B, the three burners of the left stove 6, the back stove 5, and the grill are igniting, so these three are currently accepted. Therefore, the CPU 71 creates guide audio data for designating one of these three locations currently being ignited. The CPU 71 creates, for example, guide voice data such as "Please select one from the left stove, the back stove, the grill, the fire extinguishing, and the end of the voice operation, and give a voice instruction.", And outputs the guide voice data from the speaker 77. In addition to the currently accepted locations, the options for the items explained in the guide voice include "fire extinguishing" and "end of voice operation", so if you want to extinguish the burning burner during cooking, or This is especially effective when you want to switch from voice operation to manual operation.

At the same time, the CPU 71 displays the explanation screen 102 (see FIG. 9) on the display unit 22 (S27). On the explanation screen 102, a list of currently selectable locations and items of "fire extinguishing" and "end of voice operation" are displayed with the same contents as the output voice. As a result, the user can recognize the currently accepted item choices by both voice and display, so that the word of the voice instruction can be clearly recognized. Therefore, it is possible to prevent the user from issuing a voice instruction with an incorrect word.

The user selects the location of the burner that performs the thermal power operation specified by the voice instruction from the locations notified by voice and display, and speaks to the stove 1. The CPU 71 determines whether or not the voice instruction has been received from the user (S28). When the voice instruction is not accepted (S28: NO), the CPU 71 initializes the timer t to 0 and turns it on, and determines whether or not the state of not accepting the voice instruction continues for 5 minutes (S40). If the state of not accepting the voice instruction has not continued for 5 minutes (S40: NO), the CPU 71 returns to S28 and waits until the voice instruction is received.

When the voice instruction is received from the user (S28: YES) before the state of not accepting the voice instruction continues for 5 minutes, the CPU 71 stores the received digital data of the voice instruction and the non-volatile memory 74. Of the acoustic data, the words of the currently acceptable items are matched with the acoustic data, and the above-mentioned voice recognition is performed. As a result, the CPU 71 determines whether or not the item matches the currently acceptable item (S29). If it does not match the currently accepted words for thermal power operation (S29: NO), it is a recognition failure. Therefore, in order to notify the user of the correct thermal power operation again, the CPU 71 returns to S26 and outputs the guide sound from the speaker 77 again. As a result, the user notices that the words of the thermal power operation spoken by himself / herself are incorrect, and can reconfirm the items currently accepted, so that he / she can speak to the stove 1 with the correct voice instruction.

Then, as a result of voice recognition, when the voice instruction from the user matches the currently acceptable item (S29: YES), the CPU 71 determines whether or not the recognized voice instruction is "end of voice operation". (S30). When the voice instruction is "voice operation end" (S30: YES), the CPU 71 ends the voice operation and outputs a voice "voice operation is finished" from the speaker 77 (S31). As a result, the user can recognize that the voice operation has been completed. The CPU 71 returns to S5 in FIG. 3 and repeats the above process.

On the other hand, in the state B, since the user wants to extinguish only the grill, the voice instruction for specifying the location is "grill". When the CPU 71 recognizes the voice instruction from the user as "grill" (S30: YES, S31: NO), the grill is specified as the target burner (S32). That is, since the target burner for performing the "fire extinguishing" which is the thermal power operation received earlier is the "grill", the CPU 71 creates audio data of the execution operation voice of the content of extinguishing the grill and outputs it from the speaker 77. (S33). The CPU 71 outputs, for example, an execution operation voice such as "Extinguish the grill." This allows the user to recognize that the grill is about to be extinguished.

Then, after outputting the execution operation voice, the CPU 71 executes the previously received "fire extinguishing" for the target burner "grill" based on the thermal power operation information stored in the RAM 73 (S34). Further, at the same time or slightly later than this, the CPU 71 returns the burner thermal power other than the target burner to the original thermal power by referring to the original thermal power information stored in the RAM 73 (S35). The burners other than the target burner are the left stove 6 and the back stove 5. Based on the original thermal power information stored in the RAM 73, the CPU 71 restores the thermal powers of the left stove 6 and the back stove 5 to the original thermal power before switching to the low thermal power. As a result, as shown in the state C shown in FIG. 7, the grill is extinguished, the left stove 6 can be restored from the thermal power 1 to the original thermal power 9, and the back stove 5 can be restored from the thermal power 1 to the original thermal power 3. As a result, even if a plurality of burners are ignited, only the grill can be extinguished correctly and safely by the voice instruction of the user. In the present embodiment, since the execution operation sound is output before the thermal power operation is executed, the user can recognize in advance that the thermal power will be switched, so that it is possible to prevent the thermal power from being switched unexpectedly.

Next, the CPU 71 determines whether or not there is a burner being ignited (S36). When there is a burner during ignition (S36: YES), the CPU 71 returns to S12 in FIG. 3, outputs a voice explaining the thermal power operation again, and displays the explanation screen 101 on the display unit 22 to perform the current operation. The user is made to recognize the voice instruction of the thermal power operation that can be performed, and the above process is repeated.

On the other hand, when all the burners of the stove 1 are extinguished (S36: NO), the CPU 71 ends the voice operation and outputs the voice of the end of the voice operation from the speaker 77 (S37). The CPU 71 outputs, for example, a voice saying "The voice operation is finished." The CPU 71 returns to S2 in FIG. 3, determines whether or not the burner has been ignited again, and repeats the above process.

When the voice instruction of the ignition operation is received and recognized first and there is only one burner during ignition (S20: YES in FIG. 4). Since the target burner is one burner that is currently igniting, it is not necessary to specify the location as in the case where there are a plurality of igniting burners. Therefore, if only the grill is ignited, the CPU 71 creates execution operation voice data of the content of extinguishing the grill, and outputs the execution operation voice from the speaker 77 based on the created data (S38). The CPU 71 outputs, for example, an execution operation voice such as "Extinguish the grill." After outputting the execution operation voice, the CPU 71 executes fire extinguishing, which is a thermal power operation, for the grill being ignited (S39). The CPU 71 advances the process to S36 and repeats the above process.

By the way, as described above, there is a possibility that the user forgets the state and leaves the place while using the stove 1 by voice operation. In addition, the user may suddenly lose consciousness due to a chronic disease or the like, and may not be able to use the stove 1. In such a case, it is necessary to immediately stop the operation of the stove 1 (for example, the gas combustion operation in the burner) and notify the surroundings of the state, but the stove 1 may actually be used for a long time. Therefore, it is necessary to distinguish it from it.

Therefore, for example, as shown in FIG. 3, after starting the voice operation (S8), the CPU 71 outputs a guide voice for notifying the currently acceptable thermal power operation or the like as described above (S12), and then gives a voice instruction. It is determined whether or not the state of not accepting is continued for 5 minutes (S19). Here, when the above abnormality occurs, the state of not accepting the voice instruction continues. When such a state continues for 5 minutes (S19: YES), the CPU 71 outputs the utterance instruction voice from the speaker 77 (S51) as shown in FIG. 5 in order to confirm the safety of the user. The CPU 71 calls on the user to urge the user to speak by outputting, for example, an utterance instruction voice "Please speak" OK "to the stove" from the speaker 77. The user who hears this speaks "OK" in order to respond to the call of the stove 1. The predetermined voice is not limited to "OK" and can be freely changed.

The CPU 71 determines whether or not the voice from the user has been received (S52). When the voice is received from the user (S52: YES), the CPU 71 determines whether or not the received voice is recognized as "OK" (S53). When the voice received from the user is recognized as "OK" (S53: YES), the user correctly responds to the call from the stove 1, so it is determined that there is no abnormality, and the CPU 71 processes it in S12 of FIG. Is advanced, and the guide sound is output from the speaker 77 again. As a result, the stove 1 can re-urge the user to speak the thermal power operation correctly.

Even if the user responds "OK" to the call to the stove 1 (S53: YES), the state in which the voice instruction is not spoken to the stove 1 may continue for 5 minutes (S14: NO). , S19: YES). In this case, since the CPU 71 outputs the utterance instruction voice again from the speaker 77 (S51), the safety of the user can be confirmed by periodically interacting with the user even if the user is used for a long time.

On the other hand, if the user's voice is not accepted (S52: NO), there is a possibility that some abnormality has occurred in the user, so the CPU 71 determines whether or not the manual operation of the stove 1 has been detected ( S54). When a manual operation is detected (S54: YES), it can be determined that there is no abnormality at least because the user is operating the stove 1. Therefore, the CPU 71 proceeds with the process in S12 of FIG. 3 and outputs the guide sound from the speaker 77 again. As a result, the stove 1 can correctly recognize the state of the user and prompt the user to speak the thermal power operation correctly again.

Further, when the user's voice is not received (S52: NO) and the manual operation is not detected (S54: NO), the user does not respond to the call of the stove 1 and the stove 1 is not operated. , There is a high possibility that some abnormality has occurred in the user, and it is necessary to stop the operation of the stove 1 immediately. Therefore, the CPU 71 outputs, for example, an error voice "An error has been detected, so the fire is extinguished" from the speaker 77 (S55). Further, the CPU 71 outputs a stop control signal (an example of "stop control information" of the present invention) to the motor control circuit 85, and closes the valve of the valve mechanism portion 31 of the gas amount adjusting mechanism 30 corresponding to the burner during ignition. As described above, the motor 32 is driven. As a result, the CPU 71 forcibly extinguishes all the burning burners (S56). Therefore, the stove 1 can forcibly and promptly extinguish the igniting burner if any abnormality occurs in the user while the burner is ignited, so that safety can be ensured.

Then, after the burner was forcibly extinguished, the CPU 71 displayed an error screen 103 (see FIG. 10) stating, for example, "An error occurred during voice operation. (Forcibly extinguished the fire.)". It is displayed on 22 (S57). As a result, for example, a user who has returned from the location of the stove 1 can recognize that the stove 1 has been forcibly extinguished by checking the error screen 103 displayed on the display unit 22. Further, even if not only the user who used the stove 1 by voice operation but also another person who came near the stove 1 confirms the error screen 103, the current state in which the stove 1 is extinguished and its state. Since the cause can be grasped, it is possible to take prompt action such as checking the user's situation. The CPU 71 now completes this process.

Further, even if the voice from the user is received (S52: YES), the voice of the user may not be recognized as "OK" (S53: NO). The fact that the user did not say "OK" did not respond to the call from the stove 1, for example, something was wrong with the user, or a voice different from the user's voice. May have been accepted. Therefore, even in such a case, in order to confirm the safety of the user, the CPU 71 determines whether or not the manual operation is detected (S54), and if the manual operation is not detected (S54: NO), it is determined to be abnormal. Then, the error sound is output from the speaker 77 (S55), and all the burning burners are forcibly extinguished (S56). As a result, the stove 1 can quickly extinguish the burner if any abnormality occurs in the user while the burner is ignited, so that safety can be ensured. Then, the CPU 71 displays the error screen 103 on the display unit 22 (S57) in the same manner as described above, and ends this process.

Further, after accepting the thermal power operation first, as shown in FIG. 4, in order to specify the location of the burner for the thermal power operation, the CPU 71 speaks a guide voice in order to inform the user of the currently acceptable location. Output from 77 (S26) and display the explanation screen 102 (S27). As a result, the CPU 71 calls on the user to give a voice instruction to the stove 1. However, even at this time, similarly to the above, there is a possibility that an abnormality such as the user forgetting the state and leaving the place while using the stove 1 by voice operation may occur. Therefore, the CPU 71 determines whether or not the state of not accepting the voice instruction continues for 5 minutes (S28: NO, S40). When the state of not accepting the voice instruction continues for 5 minutes (S40: YES), the CPU 71 utters, for example, "OK" to the stove, as shown in FIG. 6, in order to confirm the safety of the user. The utterance instruction voice "Please." Is output from the speaker 77 (S61). The user who hears this speaks "OK" in order to respond to the call of the stove 1.

The CPU 71 determines whether or not the voice from the user has been received (S62). When the voice is received from the user (S62: YES), the CPU 71 determines whether or not the received voice is recognized as "OK" (S63). When the received voice is recognized as "OK" (S63: YES), the user correctly responds to the call from the stove 1, so it is determined that there is no abnormality, and the CPU 71 proceeds with the process to S26 in FIG. The guide sound is output from the speaker 77 again. This allows the stove 1 to re-urge the user to speak the location of the burner correctly.

On the other hand, if the user's voice is not accepted (S62: NO), there is a possibility that the user has some abnormality, so the CPU 71 determines whether or not the manual operation of the stove 1 has been detected (S64). ). When the manual operation is detected (S64: YES), it can be determined that there is no abnormality at least because the user is operating the stove 1. Therefore, the CPU 71 proceeds with the process in S26 of FIG. 4 and outputs the guide sound from the speaker 77 again. This allows the stove 1 to re-urge the user to speak the location of the burner correctly.

If the user's voice is not accepted (S62: NO) and no manual operation is detected (S64: NO), the CPU 71 will extinguish the fire, for example, "An error has been detected." The error voice "." Is output from the speaker 77 (S65). Further, the CPU 71 outputs a stop control signal to the motor control circuit 85, and drives the motor 32 so as to close the valve of the valve mechanism portion 31 of the gas amount adjusting mechanism 30 corresponding to the burning burner. As a result, all the burning burners are forcibly extinguished (S66). Therefore, the stove 1 can promptly extinguish the burner when some abnormality occurs in the user while the burner is ignited, so that the safety can be ensured.

Then, after the burner is forcibly extinguished, the CPU 71 displays the error screen 103 on the display unit 22 (S67). As a result, for example, the user who has returned to the location of the stove 1 can recognize that the stove 1 has been forcibly extinguished by checking the error screen 103 displayed on the display unit 22. The CPU 71 now completes this process.

Further, even if the voice from the user is received (S62: YES), if the voice of the user is not recognized as "OK" (S63: NO), the CPU 71 manually confirms the safety of the user. If it is determined whether or not the operation is detected (S64) and no manual operation is detected (S64: NO), it is determined that there is an abnormality, an error voice is output from the speaker 77 (S65), and the burning burner is turned on. Forcibly extinguish all fires (S66). As a result, the stove 1 can quickly extinguish the burner when some abnormality occurs in the user while the burner is ignited, so that safety can be ensured. Then, the CPU 71 displays the error screen 103 on the display unit 22 in the same manner as described above (S67). The CPU 71 now completes this process.

As described above, the stove 1 of the present embodiment recognizes the voice instruction from the user and individually performs the thermal power operation of the plurality of burners in the ignited state. When the voice operation is started, the CPU 71 of the stove 1 determines a control command that can be currently accepted by the voice instruction, and outputs a guide voice for notifying the user of the determined control command option from the speaker 77. The control command is, for example, a control command for designating the thermal power operation of the burner, a control command for designating the location of the burner for performing the designated thermal power operation, and the like. The CPU 71 displays an explanation screen 101 (102) on the display unit 22 on which items of control commands that can be currently accepted are described. As a result, the user can give the voice instruction to the stove 1 after confirming the control command currently accepted by the voice instruction.

However, while using the stove 1 by the voice operation as described above, there is a possibility that the user forgets the state and leaves the place. In addition, the user may suddenly lose consciousness due to a chronic disease or the like, and may not be able to use the stove 1. When such an abnormality occurs, it is necessary to immediately stop the operation of the stove 1 and notify the surroundings of the state, but it is distinguished from this because the stove 1 may actually be used for a long time. There is a need. Therefore, in order to confirm the safety of the user, the CPU 71 of the stove 1 outputs an utterance instruction voice from the speaker 77 and calls for the user to speak. The utterance instruction voice is a voice that urges the user to utter a predetermined voice, for example, "OK". If the user is safe, he utters "OK" in order to respond to the call from the stove 1. When the voice received from the user is recognized as "OK", the stove 1 has been used for a long time and there is no abnormality, so the reception of the voice instruction is continued as it is.

On the other hand, if there is no "OK" utterance from the user, or if the "OK" utterance is not appropriate and cannot be recognized, there is a possibility of an abnormality, so the CPU 71, for example, "an error was detected. Therefore, the error voice "The fire will be extinguished." Is output from the speaker 77. As a result, it is possible to notify the surroundings of the abnormality in the usage state of the stove 1. Then, the CPU 71 outputs a stop control signal to the motor control circuit 85, and drives the motor 32 so as to close the valve of the valve mechanism portion 31 of the gas amount adjusting mechanism 30 corresponding to the burning burner. As a result, all the burning burners are forcibly extinguished. Therefore, the stove 1 can promptly extinguish the burner when some abnormality occurs in the user while the burner is ignited, so that the safety can be ensured. That is, by adopting such a dialogue method with the user, the stove 1 can accurately grasp the distinction between the case where the user has some abnormality and the case where the stove is used for a long time.

Further, in the above embodiment, if the voice recognition function is being executed but the voice instruction is not accepted for a long time, there is a high possibility that some abnormality has occurred in the user. In such a case, since the CPU 71 outputs the utterance instruction voice, the safety of the user can be promptly confirmed when there is a high possibility that the user has an abnormality. Therefore, the user is not made to speak more than necessary.

Further, the CPU 71 of the above embodiment determines whether or not the manual operation of the stove 1 has been detected without immediately determining an abnormality even when the state of not accepting the voice from the user continues for 5 minutes. When the manual operation of the user is detected, it can be determined that there is no abnormality because the user is in a state where the stove 1 can be operated. Therefore, the CPU 71 can continue the voice operation without extinguishing the burner.

In the above description, the CPU 71 of the control circuit 70 is an example of the "control unit" of the present invention. The CPU 71 that executes each of the voice operation control processes S51 and S61 is an example of the "utterance notification means" of the present invention. The CPU 71 that executes each of the processes of S53 and S63 is an example of the "voice determination means" of the present invention. The CPU 71 that executes the processes of S53: YES and S12 and the processes of S63: YES and S26, respectively, is an example of the "first continuation means" of the present invention. The CPU 71 that executes each process of S55 to S57 and each process of S65 to S67 is an example of the "error output means" of the present invention. The CPU 71 that executes each of the processes of S54 and S64 is an example of the "manual operation determination means" of the present invention. The CPU 71 that executes the processes of S54: YES and S12 and the processes of S64: YES and S26, respectively, is an example of the "second continuation means" of the present invention. The information displayed on the error screen 103 is an example of "abnormal information" of the present invention. The error sound output from the speaker 77 in each of the processes of S55 and S65 is an example of the "abnormal information" of the present invention.

The present invention is not limited to the above embodiment, and various modifications can be made. In the present embodiment, the built-in type stove 1 is illustrated, but it may be a table stove. The number of stoves may be one or more, and the grill may be omitted. Further, the present invention can be applied to gas appliances other than cooking cookers such as stoves, and can be applied to, for example, water heaters and the like.

In the voice operation control process of the above embodiment, when the thermal power operation is accepted by the voice instruction (S12, S13 in FIG. 3), the state of not accepting the voice instruction continues for 5 minutes (S14: NO, S19: YES). , The utterance instruction voice is output from the speaker 77 (S51), but the timing of outputting the utterance instruction voice is not limited to this, and can be freely changed. For example, after starting the voice operation (S8), the utterance instruction voice may be repeatedly output at predetermined time intervals. The same applies when accepting the location of the burner for which the thermal power operation is performed by voice instruction (S26 and S27 in FIG. 4).

In the voice operation control process of the above embodiment, after the utterance instruction voice is output from the speaker 77 (S51), the voice is not received from the user (S52: NO), or even if the voice is received, it is a predetermined voice. (S52: YES, S53: NO), the CPU 71 determines whether or not the manual operation of the stove 1 has been detected (S54), but without detecting the manual operation, each of S55 to S57 as it is. The process may be executed. The same applies to each process shown in FIG.

Further, after the utterance instruction voice is output from the speaker 77 (S51), if the user's voice is not received (S53: NO) and no manual operation is detected (S54: NO), the CPU 71 is set to S55 to S57. Each process is executed, but one or two of them may be omitted. It is preferable to extinguish at least the burning burner. As a result, the safety of the stove 1 can be ensured. In addition to extinguishing the burning burner, various operations of the stove 1 (for example, menu setting, timer setting, etc.) may be prohibited. Further, in the process of S57, the error screen 103 is displayed on the display unit 22, but any other notification method may be used as long as it can notify that an error has occurred. For example, the burning burner is forcibly forced. When the fire is extinguished, the light emitting part such as an LED or a lamp may be turned on or blinked.

In each of the voice operation control processes S19 and S40 of the above embodiment, the CPU 71 determines whether or not the state of not accepting voice continues for 5 minutes, but the state is not limited to 5 minutes and can be freely changed. ..

Further, in the above embodiment, the control circuit 70 of the stove 1 may be connected to an external terminal which is a computer so as to be able to communicate wirelessly or by wire. As the communication means, for example, a communication network such as the Internet, a cable, or a telephone line may be used. As the external terminal, for example, a stationary terminal, a mobile terminal such as a smartphone, a dedicated terminal, or the like can be used. By providing such a configuration, for example, in the voice operation control process of the above embodiment, after the utterance instruction voice is output from the speaker 77 (S51), the voice of "OK" is not received from the user (S53: NO), abnormality information can be output to the external terminal. For example, when the user loses consciousness while using the stove 1, by receiving the abnormality information from the stove 1 on the external terminal, some abnormality occurs in the user even in a place away from the stove 1. You can quickly recognize that. Therefore, even in a remote place, it is possible to promptly respond to an abnormality of the user. In addition, by connecting the stove 1 to the external terminal of a security company such as a house so that it can communicate, when the external terminal receives abnormal information from the stove 1, the security guard of the security company quickly rushes to the user's house. You can take measures such as confirming your safety. The number of external terminals to which the abnormality information is output may be plural. For example, it is possible to output the abnormality information to one or more terminals of the telephone numbers registered in advance. The terminal to be registered may be, for example, a terminal owned by the user's family, friends, relatives of the user, or the like. As a result, when an abnormality occurs in the user, the abnormality can be promptly notified to the family or the like, so that the family or the like can quickly rush to the user's house and confirm the safety.

In S7, S12, and S22 of the voice operation control process of the above embodiment, when the voice instruction is received and the recognition is completed, the speaker emits a voice for notifying that the voice has been received, for example, a chime sound of "pawn". It is preferable to output from 77. As a result, it is possible to quickly recognize whether or not the voice instruction uttered by the user is recognized by the stove 1. If the chime does not sound even after speaking, it means that the voice recognition has failed, and the user can try to speak again.

In S12 and S13 of the voice operation control process of the above embodiment, the guide sound is output from the speaker 77 and the explanation screen 101 is displayed on the display unit 22, but one of them may be omitted. Also in S26 and S27, the guide sound is output from the speaker 77 and the explanation screen 102 is displayed on the display unit 22, but one of them may be omitted. Preferably, both the audio output and the display on the display unit 22 are performed as in the above embodiment.

In S19 of the above embodiment, the thermal power of the burning burner other than the target burner is uniformly weakened to the thermal power 1, but it may be weaker than the current thermal power and may not be weakened to the same thermal power.

In the above embodiment, the location of the target burner is recognized after recognizing the voice instruction of the thermal power operation, but the location of the target burner may be recognized first and then the voice instruction of the thermal power operation may be recognized. ..

In the above embodiment, the opening degree of the valve of the valve mechanism portion 31 is adjusted by driving the motor 32 of the gas amount adjusting mechanism 30 corresponding to the burner to adjust the thermal power of the burner. However, the gas amount adjusting mechanism The structure may be any other structure. For example, the amount of gas flowing through the burner may be adjusted by providing a plurality of bypass paths and solenoid valves in the gas supply pipe and opening and closing the solenoid valves.
