(Embodiment 1)
FIG. 1 is an overall configuration diagram of a heating cooker according to the first embodiment of the present invention.

  In FIG. 1, a pan (object to be heated) 2 is placed on a top plate 1. A heating coil (heating means) 3 is disposed below the top plate 1 and generates a high frequency magnetic field to inductively heat the pan 2. The temperature detector 4 detects the lower temperature of the top plate 1, the user inputs the setting by the switch unit 5, and the result is input to the control means 6, which controls the output of the heating coil 3, The synthesizing unit 7 outputs voice data corresponding to the command from the control unit 6, and the storage unit 9 stores the command issued from the control unit 6 to the voice synthesizing unit 7 each time, and the playback selection in the switch unit 5 When the user selects the reproduction of the voice by the means 8, the command from the control means 6 stored in the storage means 9 to the voice synthesis means 7 is sent again. The voice synthesis LSI 10 receives the voice data output from the voice synthesis means 7 and outputs a voice signal. The oscillator 11 generates a clock for the voice synthesis LSI 10. The amplifier (AMP) unit 12 amplifies the voice signal, and the speaker. Reference numeral 13 denotes a configuration for converting a signal from the amplifier unit 12 and outputting a sound. In this case, the control means 6, speech synthesis means 7, and storage means 9 are constituted by a microcomputer 14.

  Hereinafter, the operation of the heating cooker having the above configuration will be described using the configuration shown in FIG. 1 and the notification sound generation program chart shown in FIG.

  First, when a notification sound generation program is started after a power switch (not shown) is turned on, a switch input process is performed in which a signal corresponding to the setting state of the switch unit 5 is sent from the control means 6 in step 15. In step 16, a temperature input process is performed in which a signal corresponding to the temperature measured by the temperature detector 4 is sent to the control means 6. In step 17, if the signal of the switch unit 5 is input from step 15, the control means 6 performs switch input determination. Then, if there is an input in this switch input determination, the switch input voice processing of step 18 is performed. Here, a signal corresponding to the setting state of the switch unit 5 selected in step 17 is converted into voice data by the voice synthesizer 7 and a voice is output. For example, when the setting of the switch unit 5 is set to automatic water heater, a sound such as “Start automatic water heater. Press the start key” is output. At this time, the signal sent from the control means 6 to the speech synthesis means 7 is also sent to the storage means 9 at the same time, and the signal is stored in the storage means 9. On the other hand, if the switch input determination at step 15 is no input, the process goes to step 19 without passing through step 18.

  In step 19, if the audio reproduction selection means 8 in the switch unit 5 has been input from step 15, the control means 6 determines the input of the audio reproduction selection means 8. When there is an input in the input determination of the audio reproduction selection means 8, the audio reproduction process in step 20 is performed. Here, the control means 6 inputs the signal stored in the storage means 9, transmits it again to the voice synthesis means 7, converts it into voice data, and outputs the reproduced voice. In the case of the previous example, a voice such as “Start automatic water heater. Press the start key” is output again. On the other hand, if the input determination of the audio reproduction selection means 8 in step 19 is no input, the process proceeds to the next step 21 without passing through step 20.

  In step 19, the temperature detector 4 in step 16 makes a dangerous temperature determination as to whether or not the current temperature is a predetermined temperature within a predetermined range. If the dangerous temperature determination is YES, the dangerous temperature voice process of step 23 is executed. For example, when approximately 220 ° C. is detected, dangerous temperature sound processing is performed. Here, a signal indicating that the temperature is equal to or higher than the predetermined temperature selected in step 21 is converted into voice data by the voice synthesizer 7 and output. For example, a sound such as “It's baked. Stop heating.” Is output. At this time, the signal sent from the control means 6 to the speech synthesis means 7 is also sent to the storage means 9 at the same time, and the signal is stored in the storage means 9. Thereafter, in step 24, the output of the heating coil 3 is stopped by the control means 6.

  In steps 15, 19, and 20, input determination of the audio reproduction selection means 8 is performed in the same manner as described above. If there is an input, audio reproduction processing is performed. Here, the control means 6 inputs the signal stored in the storage means 9, transmits it again to the voice synthesis means 7, converts it into voice data, and outputs the reproduced voice. The sound that was announced earlier, “It is baked. Stop heating.” Is output again. On the other hand, if the input determination of the audio reproduction selection means 8 in step 19 is no input, the process proceeds to step 15 again.

  If the signal indicating that the temperature is equal to or lower than the predetermined temperature is input to the dangerous temperature determination in step 21, the process proceeds to step 22 if NO. In step 22, the control means 6 determines whether or not the vehicle is in operation. And when this driving | operation determination is NO, the completion | finish audio | voice process of step 25 is performed. Here, the operation stop signal selected in step 22 is converted into voice data by the voice synthesizing means 7 to output voice. For example, a voice message “Heating is complete” is output. At this time, the signal sent from the control means 6 to the speech synthesis means 7 is also sent to the storage means 9 at the same time, and the signal is stored in the storage means 9. Thereafter, the output of the heating coil 3 is stopped by the control means 6 in steps 25 and 24.

  In steps 15, 19, and 20, input determination of the audio reproduction selection means 8 is performed in the same manner as described above. If there is an input, audio reproduction processing is performed. Here, the control means 6 inputs the signal stored in the storage means 9, transmits it again to the voice synthesis means 7, converts it into voice data, and outputs the reproduced voice. The sound “The heating is finished.” That was reported earlier is output again. On the other hand, if the sound reproduction selection means input determination in step 19 is no input, the process proceeds to step 15 again without passing through step 20.

  Further, when the operation signal is input from the switch unit 5 to the control means 6 at the time of the operation determination in step 22 and YES, the output of the heating coil 3 is continued by the control means 6 in step 26.

  As described above, in the present embodiment, voices such as switch voices, dangerous temperature voices, and end voices are generated and stored in the storage unit 9 at the same time, so that the user can input the playback selection unit 8 of the switch unit 5. If a user has missed a voice guide about switch operation, etc. that occurs when the user touches the device, he / she can listen again by switch input. This improves the usability of the equipment. In addition, when the cooking is stopped automatically, such as during automatic cooking or timer cooking, where the user may be away from the equipment, the end notification sound that was missed and the warning notification sound during cooking should be re-listened by switch input. Therefore, it is possible to clarify whether the current heating stop is normal or due to abnormal use, and the usability of the equipment is improved.

  In addition, by using the voice notification device in an induction heating cooker characterized by safety because there is no flame as in the first embodiment, induction heating cooking that is highly safe and easy to use in the home A vessel can be provided.

  The same effect can be obtained when a heating unit such as a radial heater or a gas heat source is used in place of the heating coil 3 of the present embodiment.

  Further, in the present embodiment, when the dangerous temperature is detected by providing the temperature detector 4, dangerous temperature sound processing is performed, but a pot inappropriate for induction heating (for example, a glass pot, a small diameter pot) ) With a pan detection unit that detects 2 based on differences in electrical characteristics (input current from a commercial power source, heating coil 3 current, voltage applied to the switching element of the control means 6, etc.) When performing, the same effect can be acquired also when performing the stain | pollution | contamination detection audio | voice processing by providing the stain | pollution | contamination detection part which detects the stain | pollution | contamination of the top plate 1 by the difference in the input amount of the infrared rays from the top plate 1.

  In this embodiment, only one sound signal is stored in the storage means 9 and only one sound is regenerated. However, a plurality of sound signals are stored in the storage means 9 and a plurality of sound signals are stored. Can be sequentially output and reproduced.

(Embodiment 2)
FIG. 3 is an overall configuration diagram of a heating cooker according to the second embodiment of the present invention. The time measuring means 27 measures the time during which the signal from the control means 6 is stored in the storage means 9, and when the predetermined time preset by the time measuring means 27 is timed, the signal stored in the storage means 9 is erased. Is done. The display means 28 indicates that a signal is stored in the storage means 9, and is constituted by an LCD or LED.

  The difference from the first embodiment is that a timing unit 27 and a display unit 28 are provided.

  The cooking device configured as described above will be described using the configuration shown in FIG. 3 and the notification sound generation program chart shown in FIG.

  First, a notification sound generation program is started after a power switch (not shown) is turned on. At this time, since the signal is not stored in the storage means 9, the display means 28 constituted by the LCD displays that it is not stored. Steps 15, 16, and 17 and the same processing as in the first embodiment are performed. The switch input determination is performed by the control means 6, and if there is an input to the switch unit 5 by this switch input determination, the switch input voice processing of step 18 is performed. Here, a signal corresponding to the setting state of the switch unit 5 selected in step 17 is converted into voice data by the voice synthesizer 7 and a voice is output. For example, when the setting of the switch unit 5 is set to automatic water heater, a sound such as “Start automatic water heater. Press the start key” is output. At this time, the signal sent from the control means 6 to the speech synthesis means 7 is also sent to the storage means 9 at the same time, and the signal is stored in the storage means 9. The signal stored in the storage means 9 is timed by the time measuring means 27. Since the data is stored in the storage means, the display means 28 displays that it is stored. This makes it clear to the user that the voice is stored in the storage means 9.

  In step 19, if the audio reproduction selection means 8 in the switch unit 5 has been input from step 15, the control means 6 determines the input of the audio reproduction selection means 8. When there is an input in the input determination of the audio reproduction selection means 8, the audio reproduction process in step 20 is performed. Here, the control means 6 calls in the signal stored in the storage means 9. If the time counted by the time measuring means 27 is within a predetermined time (30 seconds or less in this embodiment), the voice data is stored in the storage means 9, so the data is again transmitted to the voice synthesizing means 7 and the voice is transmitted. If the output and posted time is equal to or longer than a predetermined time (30 seconds or longer in the present embodiment), the voice data stored in the storage means 9 has been erased and no voice is output again. At this time, the display means 28 constituted by the LCD changes from being stored to displaying that it is not stored.

  On the other hand, if the input judgment of the sound reproduction selecting means 8 in step 19 is no input, the process proceeds to the next step 21 without passing through the step 20.

  As described above, in the present embodiment, when a predetermined time counted by the timing unit 27 has elapsed, the signal sent from the control unit 6 stored in the storage unit 9 to the speech synthesis unit 7 is deleted, When the user performs a reproduction operation by mistake, the user is informed of the sound before the predetermined time, and the user is prevented from being confused by, for example, the notification content being different from the current state, In addition, by providing the display means 28 for displaying that the voice is stored in the storage means 9, it is possible to confirm the presence or absence of voice notification while the user is away from the equipment, improving the usability of the equipment. To do.

  Further, in the present embodiment, the time for storing the sound generated by the switch input sound processing in the storage means 9 is measured by the time measuring means 27 and the fact that it is stored is displayed on the display means 28. The same effect is obtained not only in the voice of the switch input voice process but also in the voice generated in the dangerous temperature voice process and the end voice process.

  In the present embodiment, when a plurality of sound signals are stored in the storage means 9, the elapsed time since each sound signal is stored independently by the time measuring means 27 is counted.

(Embodiment 3)
FIG. 4 is an overall configuration diagram of a heating cooker according to the third embodiment of the present invention. The volume changing unit 29 and the voice speed changing unit 31 adjust the volume and the voice speed of the voice signal synthesized by the voice synthesizing unit 7 based on the volume data and the voice speed data received from the control unit 6. The nonvolatile storage device 31 stores the volume setting data and the voice speed setting data set by the user by the volume setting means 30 and the voice speed setting means 32 via the control means 6. The control means 6 inputs volume setting data and audio speed setting data from the nonvolatile storage device 33 as necessary.

  The difference from the first embodiment is that a volume changing unit 29, a volume setting unit 30, an audio speed changing unit 31, an audio speed setting unit 32, and a nonvolatile storage device 33 are provided.

  The cooking device configured as described above will be described using the configuration shown in FIG. 4 and the notification sound generation program chart shown in FIG.

  First, when a notification sound generating program is started after a power switch (not shown) is turned on, the same processing as in the first embodiment is performed in steps 13, 14, and 15. Switch input determination is performed by the control means 6, and when there is an input in this switch input determination, switch input voice processing of step 16 is performed. Here, a signal corresponding to the setting state of the switch unit 5 selected in step 15 is converted into voice data by the voice synthesizer 7 and output. At this time, the signal sent from the control means 6 to the speech synthesis means 7 is also sent to the storage means 9 at the same time, and the signal is stored in the storage means 9. On the other hand, if the switch input determination at step 15 is no input, the process goes to step 19 without passing through step 18.

  In step 19, if the audio reproduction selection means 8 in the switch unit 5 has been input from step 15, the control means 6 determines the input of the audio reproduction selection means 8. When there is an input in the input determination of the audio reproduction selection means 8, the audio reproduction process in step 20 is performed. Here, the control means 6 inputs the signal stored in the storage means 9, transmits it again to the speech synthesis means 7, converts it into speech data, and outputs the speech. At the same time, the volume and voice speed of the switch input voice processing in step 18 are transmitted from the control means 6 to the volume changing means 29 and the voice speed changing means 31, and the volume changing means 29 and the voice speed changing means 31 are based on the received signals. Volume adjustment and voice speed adjustment are performed. The volume can be freely set by the volume setting means 30 and the voice speed can be freely set by the voice speed setting means 32.
