(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 inputs a command from the control unit 6 and outputs voice data corresponding to the command. The volume adjusting unit 8 inputs the volume of the voice signal synthesized by the voice synthesizing unit 7 from the control unit 6. The sound synthesizing LSI 9 inputs the sound data output from the sound synthesizing means 7 and outputs a sound signal, the oscillator 10 generates a clock for the sound synthesizing LSI 9, and the amplifier (AMP) unit 11 The audio signal is amplified, and the speaker 12 is configured to convert the signal from the amplifier unit 11 and output the audio. In this case, the control means 6, the voice synthesis means 7, and the volume control means 8 are constituted by a microcomputer 41.

  Hereinafter, the operation of the heating cooker having the above-described configuration will be described using the notification sound generation program chart shown in FIGS. 1 and 2.

  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 13. In step 14, the control means 6 performs temperature input processing according to the temperature measured by the temperature detector 4. In step 15, if the signal of the switch unit 5 is input in step 13, the control means 6 performs switch input determination. If there is an input in this switch input determination, the switch input voice processing in step 16 is performed. Here, a signal corresponding to the setting state of the switch unit selected in step 15 is converted into voice data by the voice synthesizer 7 and output. At the same time, a signal indicating that the volume of the switch input voice processing is low (40 dB in the first embodiment) is transmitted from the control means 6 to the volume adjusting means 8 to the volume adjusting means 8, and the volume adjustment is performed based on the received signal. The means 8 adjusts the volume. For example, when the setting of the switch unit 5 is set to automatic water heater, a voice such as “Start automatic water heater” is output at a low volume. On the other hand, if the switch input determination at step 15 is no input, the process goes to step 17 without going through step 16. In step 17, the temperature detector 4 in step 14 determines whether the current temperature is a predetermined temperature within a predetermined range. If this dangerous temperature determination is YES, the dangerous temperature voice process of step 19 is executed, and then the output is stopped in step 21. For example, output is stopped when approximately 220 ° C. is detected. Here, a signal indicating that the temperature is equal to or higher than the predetermined temperature selected in step 17 is converted into voice data by the voice synthesizer 7 and output. At the same time, a signal is sent from the control means 6 to the volume adjusting means 8 that the volume of dangerous temperature sound processing is set to a high volume (80 dB in the first embodiment), and the volume adjusting means 8 is adjusted based on the received signal. The means 8 adjusts the volume. For example, a sound such as “It's baked. Stop heating.” Is output at a high volume. Thereafter, in step 21, the output of the heating coil 3 is stopped by the control means 6. If a signal indicating that the temperature is equal to or lower than the predetermined temperature is input to the dangerous temperature determination in step 17, the process proceeds to step 18 if NO. In step 18, 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 20 is performed, and the output of the heating coil 3 is stopped at step 21 after that. Here, the operation stop signal selected in step 18 is converted into voice data by the voice synthesizer 7 and output. At the same time, a signal is sent from the control means 6 to the volume adjusting means 8 that the volume of the end voice processing is high (80 dB in this embodiment), and the volume adjusting means 8 adjusts the volume based on the received signal. For example, “Heating is complete” is output at a loud volume. Thereafter, in step 21, the output of the heating coil 3 is stopped by the control means 6. 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 18, if YES, the output of the heating coil 3 is continued by the control means 6 in Step 22.

  As described above, in this embodiment, the volume of dangerous temperature sound processing and end sound processing is set to a high volume, and the volume of switch sound processing is set to a low volume, so that the user touches the device. The high-frequency notification sound that is generated during the operation is not harsh, while the end of the automatic cooking or timer cooking and the warning notification sound that the user may be away from the device are surely heard. Thus, the user's usability and safety can be improved.

  In addition, as described in the first embodiment above, by using a voice notification for an induction heating cooker characterized by safety because there is no flame, induction is highly safe and easy to use in the home. A cooking device 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.

  In the present embodiment, the temperature detector 4 is provided to detect the dangerous temperature, and the dangerous temperature sound processing is performed. However, the pan is inappropriate for induction heating (for example, a glass pan, a small-diameter pan). 2 is equipped with a pan detection unit that detects the difference in electrical characteristics (input current from a commercial power source, current in the heating coil 3, voltage applied to the switching element of the control means 6, etc.) and performs inappropriate pan use audio processing. 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 upper part.
