The heating coil 3 is disposed below the top plate 1 and induction-heats the pan 2 by generating a high-frequency magnetic field. The induction heating means 4 supplies a high frequency current to the heating coil 3, and is constituted by a switch element, a smoothing capacitor, and the like. The temperature detector 5 is a temperature sensitive element such as a thermistor and detects the lower temperature of the top plate 1. The operation means 6 includes a “selection” switch for selecting a cooking menu, an “up” switch and a “down” switch for setting a heating power and a temperature, a “plus” switch and a “minus” switch for setting a timer, and start and stop of cooking. The “start / stop” switch for performing the operation and the “switch” switch for switching the mode are input. The result of the user pressing each switch is input to the control means 8, and the control means 8 is set by the display means 9. The display according to the heating power and temperature is performed, and the control means 8 heats the pan 2 by the induction heating means 4 according to the cooking menu and the heating power and temperature. Furthermore, in order to perform voice guidance, the voice synthesizing means 10 generates a waveform for outputting voice and outputs it to the speech speed converting means 11 in accordance with the output of the control means 8. The speech speed conversion means 11 inputs the speed of the voice guide according to the operation mode from the control means 8, changes the voice waveform input from the voice synthesis means 10 according to the speed of the voice output, and outputs it from the speaker 12. To do. The device information storage means 13 is composed of a non-volatile memory, and stores a use history, a failure history, and a misuse history by an output from the control means 8.

  Further, the control means 8, the speech synthesis means 10, and the speech speed conversion means 11 are realized by separate microcomputers, but it may be realized at a low cost by one microcomputer.

  Further, the speech speed conversion means 11 can convert the playback speed to an arbitrary speed by the voice synthesis means 10 without changing the pitch of the voice from the digitized voice signal.

  Next, the operation state of the induction heating cooker in Embodiment 1 of this invention is demonstrated using FIGS. 2-5.

  FIG. 2 is a diagram showing a relationship between operation modes and functions of the induction heating cooker according to Embodiment 1 of the present invention.

  As shown in FIG. 2, in the operation mode in which all functions can be used, all functions as a cooker can be used, and in a mode in which only limited functions can be used, only a heating function can be used as a cooker. In the first embodiment, since only the heating function can be used in the second operation mode, the operation is very simple in the second operation mode, and the operation can be easily performed even by a child or an elderly person. In the device information notification mode, the function as a cooking device cannot be used, and the use history, failure history, and misuse history stored in the device information storage means 13 are continuously notified by voice.

  FIG. 3A is a diagram illustrating a display example of an operation mode in which all functions can be used.

  In FIG. 3A, the function corresponding to “heating”, “tempura”, “boiling water”, “rice cooking”, “rice porridge” on the display means 9 is selected by the “selection” switch of the operation means 6, and the “start / stop” switch is used. The heating operation is started or stopped. When “Heating” is selected, the heating power can be set by the “Up” and “Down” switches. Further, the timer time can be set by a “minus” switch and a “plus” switch. When the timer time is set, the remaining time until the end of cooking is displayed in the time display area 9a of the display means 9. When “tempura” is selected, the oil temperature control temperature can be set by the “up” switch and the “down” switch. In “rice cooking” and “rice porridge”, the amount of cooking rice can be set by the number of cups by the “up” switch and the “down” switch.

  Thus, since all functions can be used, complicated operations are required.

  When the “switch” switch which is the operation mode switching means 7 is pressed, the mode shifts to a mode in which only limited functions can be used.

  FIG. 3B is a diagram illustrating a display example of an operation mode in which only limited functions can be used.

  In FIG. 3B, “Easy” is displayed on the display means 9, and the operation means 6 does not have the “select” switch in FIG. 2A, and only the “heating” function of the display means 9 can be selected. The heating operation is started or stopped by a “start / stop” switch. Further, the “minus” switch and the “plus” switch in FIG. 2A are not provided, and the timer cooking operation cannot be performed.

  In this way, by making it impossible to select a function that is not frequently used and eliminating complicated operations, it can be easily used by children and the elderly.

  When the “switch” switch which is the operation mode switching means 7 is pressed, the mode shifts to a mode in which all functions can be used.

  FIG. 4A is a diagram illustrating a display example when the speech speed of the voice guide is set in an operation mode in which all functions can be used.

  "0" is displayed in the time digit of the time display area 9a of the display means 9, and the numerical value from "05" to "15" is displayed in two digits in the minute digit, and the speed is determined from the value obtained by dividing this numerical value by 10. Set. Therefore, in the case of [05], the voice speed is 50%, and in the case of “15”, the voice speed is 150%. In the case of “10”, the speech speed conversion means 11 does not perform the speech speed conversion and outputs the speech waveform generated by the speech synthesis means 10 from the speaker 12 without processing.

  When the “UP” switch is pressed, the voice guide speech speed is set in an operation mode in which only limited functions can be used.

  FIG. 4B is a diagram showing a display example when setting the speech speed of the voice guide in the second operation mode in which only limited functions can be used.

  "1" is displayed in the time digit of the time display area 9a of the display means 9, and numerical values from "05" to "15" are displayed in two digits in the minute digit, and the speed is calculated from this numerical value. In the case of “13”, the speech speed conversion unit 11 generates a speech waveform having a speed increased by 30% from the speech waveform generated by the speech synthesis unit 10 and outputs it from the speaker 12.

  When the “down” switch is pressed, the voice guide speech speed is set in the first operation mode in which all functions can be used.

  FIG. 5 is a list of examples of voice guidance in the second operation mode.

  In the first operation mode used by the user who is accustomed to the usage of the device, the voice guide feels annoying to the user who is accustomed to the usage of the device, if the change of the setting of the device or the situation is notified successively. , Do not inform. However, in order for the child, the elderly, and the visually impaired to be able to use it safely and safely, in the second notification mode, device settings and changes in the situation are sequentially notified.

  FIG. 6 shows device information output by voice in the device information notification mode.

  When the device information notification mode is entered by the mode switching means 7 in FIG. 1, the device information shown in the list is sequentially and repeatedly notified by voice. If the device is in the device information notification mode when a device breaks down or cannot be used successfully, and the device is in the device information notification mode, the service personnel will use the device after purchasing the device, the number of power failure detections, and failure information. In addition, misuse information can be obtained directly from the device by voice, and the service can be handled accurately.

  As described above, in the present embodiment, it is possible to switch between an operation mode in which all functions can be used and at least one operation mode in which only limited functions can be used. The means 11 outputs voice at different speaking speeds in each of a plurality of operation modes, thereby enabling voice output at an easy-to-hear speed according to the user, and operation with limited functions. When used in the mode, it is possible to provide a safe and comfortable induction heating cooker that is easy to hear and understand even for children and elderly people by reducing the speed of the guide voice. In addition, when a device breaks down, the device information can be notified by voice by switching to the device information notification mode via a phone call between the user and the repair service person. Can give appropriate advice on misuse.

  In this embodiment, the speech speed is switched between two operation modes, that is, an operation mode in which all functions can be used and an operation mode in which only “heating” can be used. For example, any number may be used, and it is more preferable that an operation mode is prepared according to the number of users and the speech speed can be set in each mode.

  In the present embodiment, the speech speed is switched in each operation mode. However, by switching the volume and pitch, a voice guide function that is easy to hear for the user can be realized.

  As described above, the induction heating cooker according to the present invention has a voice guide function, and since the voice reproduction speed is set according to the user and the voice is output at an easy-to-listen speed, it has a voice guide function. It can also be applied to improve the safety and convenience of various devices.
