As illustrated in FIG. 7, the display setting input screen can be configured such that the user selects a character size, a font, a character color, a background color, and a language from three options according to his / her preference. As illustrated in FIG. 8, the voice setting input screen can be configured such that the user selects a volume, a height, a speed, a language, and a special from three options according to his / her preference. The cooking device 61 is configured to be able to change the character display form and the sound output form of the setting contents, so that it is possible to perform operations on the setting screen according to the user's preference and age. Convenience and comfort can be improved. In particular, according to the configuration in which the audio setting can be changed, an optimal cooking environment can be provided even for elderly people with reduced hearing ability. However, the setting items, the number of options, and the contents of options on each input screen may be increased / decreased / changed as appropriate.

  In the preference menu setting input screen, as illustrated in FIG. 9, when the user selects whether or not to execute as necessary and performs preference menu settings (when “Yes” is selected). Can be configured to allow the user to select manual or automatic settings. When manual setting is selected, the user may register an arbitrary number of favorite menus, such as registering the top five favorite menus. The person may set as appropriate.

  Here, the operation processing unit 43a has a function of sequentially storing functions and menus used by registered individuals in the operation history storage unit 45b, and inputs to the upper surface operation unit 3 and the front operation unit 4 by the user. The contents are stored in the storage unit 45 in association with the registration authentication data. That is, when a function such as a menu or fried food registered in the cooking device is set in advance, the operation processing unit 43a generates operation history information related to the operation as necessary, and an operation history storage unit 45b. When the operation signal for the priority display (automatic setting) of the menu or function related to the individual control information setting is sent from the upper surface operation unit 3 by the registered user's input operation and the registered user's input operation A function of selecting a frequently used menu or function and displaying it on the main operation unit 27 with reference to the operation history information in the history storage unit 45b. In the screen as shown in FIG. 9, when the user selects the automatic setting, the operation processing unit 43a has a high usage frequency among the usage histories recorded in the operation history storage unit 45b. Control menus / functions to be displayed with priority, and let the user select them.

  Moreover, the setting content has restriction information. The restriction information is information set to restrict functions that can be used by the user in advance. On the restriction information setting input screen, the user can input and set restriction information such as function restriction, menu restriction, thermal power restriction, and temperature restriction as necessary. For example, an upper limit (upper limit value) of thermal power and temperature is set in advance for a user who is not suitable for high-temperature cooking such as a child or an elderly person. By setting the upper limit value, the cooking device 61 can be set to drive only up to the upper limit value regardless of the operation of the user. Moreover, you may make it provide the restriction | limiting which sets the function (fried food function etc.) built in the heating cooker 61 beforehand as unusable.

  When the registration operation by the user is completed, the operation processing unit 43a causes the main operation unit 27 to display a setting confirmation screen. In addition to the setting contents, for example, a YES button that the user presses when there is no change in the setting contents and a NO button that the user presses when there is an error in the setting contents are displayed on the setting confirmation screen. The user can select whether or not there is a change. When receiving no change instruction from the user, the operation processing unit 43a completes the registration of the setting contents, and the operation control unit 43c starts individual control of the cooking device 61. If there is a change in the content confirmed on the setting confirmation screen, the user selects information to be changed, and the operation processing unit 43a that has received this selection instruction displays again the input screen for the information that the user wants to change. When the information change by the user is completed, the “setting confirmation screen” is displayed again. When registration is selected by the user, the operation processing unit 43a stores the biometric information input in real time in the registration information storage unit 45a together with the registered setting contents. When a personally authenticated user desires individual control, the operation control unit 43c reads information stored in the registration information storage unit 45a, and the heating control unit 44, the grill heater drive circuit 21, the display drive circuit 19, A thermal power control signal, a grill control signal, a display control signal, and a voice control signal (individual control signal) are sent to the voice synthesizer 22, respectively. The menu screen displayed on the main operation unit 27 shows a setting change button for changing individual setting contents. When the user touches the setting change button, the operation processing unit 43a displays the setting change button shown in FIG. A user information registration screen like this is displayed. As a result, the user can select an item whose setting content is to be changed and appropriately change the setting content to a desired state. In addition, the data of the administrator who manages the information stored in the storage unit 45 is stored in the storage unit 45 in association with the registration authentication data, and the operation control unit 43c is operated by the administrator via the upper surface operation unit 3. The information stored in the storage unit 45 may be changed in response to a request from the user.

  The heating control unit 44 is connected to each inverter circuit including the inverter circuit 17 and the temperature detection device 13 via a signal line, and the temperature detected by each temperature sensor 11a, 11b, 12 via the temperature detection device 13. Is something to get. And the heating control part 44 controls the heating electric energy of the heating parts 8-10 by controlling the high frequency current output to the designated inverter circuit according to the control signal transmitted from the operation control part 43c. is there.

  Further, the heating control unit 44 outputs a high frequency to the inverter circuit when no control command is input from the operation control unit 43c until a predetermined time elapses after the high frequency current is output to each inverter circuit. It has a function to stop current output. That is, the heating control unit 44 executes the forgetting to cut-off process for stopping the heating of the object to be heated when the non-operation duration time during which no operation is performed by the user exceeds a predetermined time set in advance. Furthermore, when the temperature of the object to be heated detected by the temperature sensors 11a, 11b, and 12 exceeds a predetermined temperature, the heating control unit 44 provides a high-frequency current to the inverter circuit corresponding to the temperature sensors 11a, 11b, and 12 Is stopped, and an overheat prevention process for stopping the heating of the corresponding object to be heated is executed.

  Subsequently, the operation of the cooking device 61 until the user starts cooking and during cooking is described based on the flowcharts of FIGS. 10 and 11. First, the flow of user authentication processing (authentication flow) will be described with reference to FIG.

  When the upper main power switch 7a or the front main power switch 7b is turned on by the user, power is supplied from the power supply unit 14 to the control unit 16 and the like (FIG. 10: step S101). Next, the operation control unit 43 c transmits a display control signal for displaying a guide for prompting authentication to the display drive circuit 19, and a guide for prompting authentication is displayed on the main display unit 29. At the same time, the operation control unit 43c transmits a voice control signal to the voice synthesizer 22, and a guide for prompting authentication is notified by voice from the speaker 23 (FIG. 10: Step S102).

  When a user who confirms that the user is prompted to authenticate by visually recognizing a guide that prompts authentication performs a touch operation on the authentication unit 5 (authentication window 37), the authentication data generation device 15 generates biometric information and a verification determination unit. 43b (FIG. 10: step S103). The collation determination unit 43b collates (compares) the biometric information input from the authentication data generation device 15 with the registration authentication data in the registration information storage unit 45a, and obtains the matching rate (F) (FIG. 10: Step S104). Here, the matching rate (F)% is, for example, “matching rate (F)% = (coincidence point / total detection point) × 100”.

  The collation determination unit 43b determines that “if (F)> (A)” is present when there is registration data with a precision (F) exceeding a preset authentication threshold (A) (FIG. 10: Step S105 / Yes). The biometric information and the registered authentication data are regarded as matching, and the matching is notified to the operation control unit 43c. Receiving the notification from the collation determination unit 43b, the operation control unit 43c reads the individual setting contents registered in the registration information storage unit 45a (FIG. 10: Step S106), and based on the read setting contents, cooking is performed. Individual control (control in personal mode) of the device 61 is started, and data corresponding to the individual setting contents of the user is output to the display unit 20 and the upper surface operation unit 3 (FIG. 10: step S107).

  That is, when the individual setting contents are displayed on the display unit 20 by the control by the operation control unit 43c and the sound based on the individual setting contents is notified from the speaker 23, the user uses his / her individual setting. be able to. For example, when the user touches a cut-off switch corresponding to the heating unit 8, power is supplied from the power supply unit 14 to the inverter circuit 17 through the control unit 16, and the heating unit 8 is ready for driving. At this time, for example, the right IH thermal power display unit 30R is displayed in blue to indicate that it is in a heating preparation state. When the user performs a touch operation on the heating power setting switch or the automatic cooking switch corresponding to the heating unit 8, the operation control unit 43 c drives the inverter circuit 17 to start induction heating by the heating unit 8. Thereafter, the user operates the heating power setting switch and the turn-off timer switch to perform desired cooking. Details of the registration process of individual setting contents will be described in detail in the following registration flow (FIG. 11).

  When the user uses a function or menu registered in the cooking device 61 in advance, the operation processing unit 43a stores the used function or menu in the operation history storage unit 45b as an operation history. That is, after the user starts control in the personal mode, the operation processing unit 43a stores the operation history information while the user performs a desired cooking by operating the heating power setting switch, the turn-off timer switch, or the like. The process is executed (FIG. 10: Step S108). Subsequently, when the user performs an off operation by touching the cut-in switch, the operation control unit 43c stops driving the inverter circuit 17 via the heating control unit 44, and supplies power from the power supply unit 14 to the inverter circuit 17. Stop. Then, the power supply unit 14 cuts off its own power supply (FIG. 10: Step S109).

  On the other hand, when there is no registration data with the precision (F) exceeding the authentication threshold (A) (in the case of (F) ≦ (A)) (FIG. 10: Step S105 / No), the operation control unit 43c. However, the fact that the user is not registered (not registered) is output by display and voice (FIG. 10: step S110). Next, the operation control unit 43c outputs a display and a sound prompting the user to confirm whether or not to use the heating cooker 61 (whether or not to use IH) (FIG. 10: Step S111). The operation control unit 43c receives the user's operation for notification of whether or not to use, and when the user determines to use the heating cooker 61 (FIG. 10: Step S111 / Yes), in real time. The acquired biometric information is temporarily stored in the storage unit 45 (FIG. 10: Step S112), and the process proceeds to a registration flow (FIG. 11) described later. On the other hand, when the user determines not to use the heating cooker 61 (FIG. 10: Step S111 / No), the operation control unit 43c supplies power from the power supply unit 14 to the inverter circuit 17 via the heating control unit 44. The supply is stopped, and the power supply unit 14 shuts off its own power supply (FIG. 10: Step S109).

  Next, a flow of user information registration processing (registration flow) will be described with reference to FIG. 11 showing user information registration processing at power-on. When there is a registration request from the user, the operation processing unit 43a reads the authentication input screen from the storage unit 45 and displays the authentication input screen as shown in FIG. 6 on the main operation unit 27 (FIG. 11). : Step S201). When the user inputs personal information such as name, gender, age group, etc. from the personal information input screen and registration of the personal information is completed (FIG. 11: step S202), the operation processing unit 43a performs provisional authentication. The stored biometric information is stored in the registered information storage unit 45a in association with the input personal information (FIG. 11: Step S203). In this step S203, the process of registering the temporarily stored data is performed. However, the biometric information is again acquired from the authentication unit 5 by displaying a guide prompting the user to authenticate or the like. It may be.

  Next, when the operation processing unit 43a displays the input screen for setting individual control information on the main operation unit 27, the user can display the display settings and voices as shown in FIGS. Enter individual control information such as settings and preference menu settings. When the registration of the individual control information by the user is completed, the operation control unit 43c stores the input individual control information in association with the biological information in the registration information storage unit 45a (FIG. 11: Step S204). Of the individual control information, the preference menu is set as required by the user as illustrated in FIG. 9, and manual setting or automatic setting can be selected. A user who has selected manual setting can register an arbitrary number of preset favorite menus. When the user selects automatic setting, the operation processing unit 43a preferentially displays from the menu / function that is frequently used by the user in the operation history information stored in the operation history storage unit 45b. . However, since the operation history information of the user is not stored at the time of initial registration, the operation processing unit 43a may display on the main operation unit 27 that it is not stored, or it has already been registered. Operation history information created in advance based on user operation history information, general statistical data, or the like may be displayed. When a plurality of users are registered, the operation history information of the entire user may be displayed statistically or selectively.

  Subsequently, when the operation processing unit 43a displays a restriction information setting input screen on the main operation unit 27, the user inputs restriction information for restricting functions that can be used in advance from the restriction information setting input screen. . When the registration of the restriction information by the user is completed, the operation processing unit 43a associates the input restriction information with the personal information and stores it in the registration information storage unit 45a (FIG. 11: Step S205). The restriction information includes information related to function restriction, menu restriction, thermal power restriction, temperature restriction, and the like, and is information set by the user as necessary.

  Then, the operation control unit 43c displays a setting confirmation screen on the main display unit 29 (FIG. 11: Step S206). When the user who has confirmed the display of the setting confirmation screen indicates that there is no change (FIG. 11: Step S207 / Yes), the operation processing unit 43a completes registration of the registration authentication data (FIG. 11: Step). S208), the operation control unit 43c starts individual control of the heating cooker 61 (the process proceeds to step S106 in FIG. 10).

  When the content confirmed on the setting confirmation screen is changed, when the user selects information to be changed by the main operation unit 27 (FIG. 11: Step S207 / No), an operation signal indicating the selection is transmitted to the operation processing unit 43a. Then (FIG. 11: Step S209), the operation processing unit 43a causes the main operation unit 27 to display again an input screen for information that the user wants to change (FIG. 11: Step S210). When the user completes the information change in the main operation unit 27 (FIG. 11: Step S211), the operation processing unit 43a causes the main operation unit 27 to display the “setting confirmation screen” again (FIG. 11: Step S206). . The subsequent operation contents are the same as those in steps S207 to S211.

(Effect of 1st Embodiment)
In the first embodiment, the cooking device 61 has a personal authentication function, and adopts a configuration in which individual control is performed based on the setting content associated with the authenticated user. It becomes possible to drive the heating cooker based on settings according to the user's situation (for example, an elderly person whose hearing ability has decreased), and the convenience and comfort can be improved. That is, in the heating cooker 61, when the user touches the authentication unit 5, the authentication unit 5 generates biometric information based on information obtained from the user, and the control unit 16 generates the biometric information in the authentication unit 5. Since the personal authentication (biometric authentication) is performed by collating the biometric information that has been stored and the registration authentication data stored in advance in the storage unit 45, it is not necessary for the user to perform complicated operations. A cooking device excellent in properties can be provided. Moreover, according to the heating cooker 61, since restriction information is included in the setting contents, it is possible to restrict the use to a specific user, so that it is possible to prevent unexpected driving and reduce erroneous operations.

<Modification 4>
Modification 4 of the heating cooker according to the first embodiment of the present invention will be described with reference to FIG. The cooking device according to the fourth modification is characterized in that a user has a function (self-check function) for self-checking whether authentication is correct or incorrect when authenticating biometric information. In the heating cooker 61D of the fourth modification, the same components as those in the heating cooker 61 are denoted by the same reference numerals, and the description thereof is omitted.

  Here, operation | movement of the heating cooker 61D in this modification 4 provided with the function which makes a user self-check an authentication result is demonstrated based on the flowchart shown in FIG. First, when the user turns on the top main power switch 7a or the front main power switch 7b, power is supplied to the control unit 16 and the like (FIG. 17: step S501). Next, the operation control unit 43c displays a guide for prompting mode setting on the main display unit 29 (FIG. 17: Step S502). When the user performs a touch operation on the authentication unit 5, the authentication data generation device 15 generates biometric information (FIG. 17: step S503), and the verification determination unit 43b executes data verification (FIG. 17: step). S504), the precision (F) is compared with the authentication threshold (A) (FIG. 17: step S505). The above operation contents are the same as steps S101 to S105 in FIG. That is, when there is no registered authentication data that matches the biometric information (FIG. 17: Step S505 / No), the control unit 16 executes unregistered processing similar to that after Step S110 in FIG. 10 (Authentication Flow).

  On the other hand, when it is determined that there is registered authentication data that matches the authentication data (FIG. 17: Yes in step S505), the collation determination unit 43b notifies the operation control unit 43c of the determination result. The operation control unit 43c uses the determination result notified from the collation determination unit 43b as a guide for the user to confirm whether the information associated with the registration authentication data and the determination result are correct (prompt for correctness check). It is output together with the guide (FIG. 17: step S506). In outputting each information, all information may be notified by display and voice. For example, a guide for prompting a determination result or correctness confirmation is notified by both display and voice, and personal information, etc. The output method may be changed according to information, such as only displaying.

  When the user indicates that the authentication result is correct in the main operation unit 27 (FIG. 17: Yes in step S507), the collation determination unit 43b re-compares the authentication data with the matched registration authentication data. In this re-comparison, the collation determination unit 43b uses a preset warning threshold (B) (FIG. 17: Step S508).

  When the relevance rate (F) is equal to or greater than the alerting threshold value (B), “if (B) ≦ (F)”, the process proceeds to step S106 in FIG. That is, the operation control unit 43c reads individual setting information and executes individual control in the same manner as the authentication flow shown in FIG. On the other hand, when the relevance rate (F) is less than the alerting threshold value (B), “when (A) <(F) <(B)”, the collation determination unit 43b displays the result of the recomparison as the operation control unit 43c. And the operation control unit 43c outputs a guide for prompting the authentication unit 5 to confirm. That is, the operation control unit 43c displays a guide for prompting authentication unit confirmation and authentication unit cleaning on the main display unit 29, and notifies the speaker 23 of the guide (FIG. 17: step S509). Thereafter, as shown in FIG. 17, the process may directly move to step S <b> 106 in FIG. 10, or the user may be prompted to re-authenticate.

  Moreover, when the user selects an error in the authentication result in the main operation unit 27, that is, when the registrant authenticated by the heating cooker 61 and the user do not match (FIG. 17: Step S507 / No). ), The collation determination unit 43b sets N = 1 as the count number N of the authentication number counter built in the cooking device 61. That is, in the authentication number counter, the initial value of the count number N is set to 0 (FIG. 17: Step S510). Then, the collation determination unit 43b compares the count number N with a preset misidentification reference count C. If the count number N is less than the misidentification reference count C, the operation control unit 43c sets the count number N to the misidentification reference count. In response to this notification, the operation control unit 43c outputs a guide for prompting confirmation by the authentication unit 5 and a guide for prompting re-authentication (FIG. 17: steps S512 and S513). When the user touches the authentication unit 5 again according to the output of each of the guides, the re-authentication process after step S503 is performed.

  Also in this re-authentication process, when the user selects an error in the authentication result (FIG. 17: Step S507 / No), the collation determination unit 43b adds 1 count to the count number N of the authentication count counter and adds N = 2 (FIG. 17: Step S510). The re-authentication process is executed until the count number N becomes equal to or greater than the misidentification reference count C (until the count number N and the misidentification reference count C match) (FIG. 17: Step S511).

  When the count number N and the misidentification reference count C coincide with each other by the increment of the count number N in step S510 (FIG. 17: step S511 / No), the collation determination unit 43b has the count number N equal to or greater than the misidentification reference count C. To the operation control unit 43c, and the operation control unit 43c outputs an authentication failure (authentication NG) message (FIG. 17: step S514). Next, the operation control unit 43c notifies whether or not registration re-execution is performed, and when the user selects registration re-execution (FIG. 17: Step S515 / Yes), the registration flow shown in FIG. Transition.

  When the user does not select re-registration (FIG. 17: Step S515 / No), the operation control unit 43c notifies whether to switch to the Everone mode, and the user confirms the Everone mode. When switching to is selected (FIG. 17: Step S516 / Yes), the process proceeds to Step S404 in FIG. 16, the Everone mode setting is read, and control in the Everone mode is started. When the user does not select switching to the Everone mode (FIG. 17: Step S516 / No), the operation control unit 43c turns off the power of the cooking device 61 (FIG. 17: Step S517).

  In the fourth modification, the operation using the matching rate of the detection points is described as the comparison data of the self-check function. However, as the comparison data of the self-check function, the authentication data detection device is used for creating image data. Data, for example, the light amount of the video element (optical type) or the charge amount of the electrode (capacitance type) may be used.

(Effect of Modification 4)
Since the cooking device 61D of the fourth modification is provided with a function that allows the user to self-check the authentication result, the user can be provided with an opportunity to confirm the correctness of the biometric authentication. It is possible to reduce the possibility of erroneous detection due to dirt or the like, and to reduce the trouble of resetting the user and the reduction in work efficiency caused by the malfunction based on the erroneous detection.

There is a feature in the point. In other words, it has a personal only mode limited to the personal mode and an everly only mode limited to the everone mode. In the heating cooker 61E of the fifth modification, the same components as those in the heating cooker 61 are denoted by the same reference numerals, and the description thereof is omitted.

  Here, operation | movement of the heating cooker 61E in this modification 5 which has a mode limitation function is demonstrated based on the flowchart shown in FIG. When the user turns on the main power switch 7 and power is supplied to the control unit 16 and the like (FIG. 18: step S601), the control unit 16 outputs a guide for prompting the setting of the limited mode (FIG. 18: step). In step S602), the user executes mode selection (FIG. 18: step S603). Here, when the user selects the Everone Only mode, the control unit 16 determines the Everone mode (FIG. 18: Step S604), and similarly to Steps S504 and S505 of FIG. The setting data for Everone mode registered in 45a is read (FIG. 18: step S608), and control of the heating cooker 61 is started based on the setting information of the Everone mode (FIG. 18: step S609). Further, the control unit 16 performs control so as not to display a prompt to change the mode setting on the menu screen.

  Further, when the personal only mode is selected by the user, the control unit 16 determines the personal mode (FIG. 18: step S605), moves to step S102 in FIG. Based on the individual control information registered in the storage unit 45a, the individual control of the cooking device 61 is started. Also in this case, the control unit 16 performs control so as not to display a prompt to change the mode setting on the menu screen.

  When the switchable mode is selected by the user (FIG. 18: Step S606), the control unit 16 prompts the user to confirm whether to use the heating cooker 61 in the Everone mode or the personal mode. When the Everone mode is selected, the control of the heating cooker 61 is started based on the setting information of the Everone mode as described above (FIG. 18: Steps S608 and S609). On the other hand, when the personal mode is selected by the user, the process proceeds to step S102 in FIG. 10 as described above, and the individual control of the heating cooker 61 based on the individual control information is started.

  During use of the heating cooker 61 in each of the above modes, the user can switch the limited mode by selecting the limited mode change displayed on the menu screen. That is, when the limited mode change is selected by the user, the control unit 16 prompts the user to confirm whether or not to change the limited mode, and when the user selects to change the limited mode (FIG. 18: In step S610), the process returns to step S602 to execute the limited mode changing process. On the other hand, when the user selects the limited mode unchanged, the control unit 16 continues to control the heating cooker 61E according to the setting before selecting the limited mode change on the menu screen (FIG. 18: step S611).

(Effect of Modification 5)
Since the cooking device 61 of the fifth modification has a function of limiting the mode, the user selects the setting of the use mode every time the power is turned on for the user who uses either the individual mode or the Everone mode limitedly. Therefore, the user's troublesomeness can be eliminated.
