Description

  The present invention relates to a heating cooker used for a kitchen for home use or business use.

  Conventionally, an induction heating cooker will be described as this type of cooking device. FIG. 6 is a configuration diagram of an induction heating cooker as a conventional heating cooker. In FIG. 6, a pan 27 is placed on the top plate 26. The heating coil 28 is disposed below the top plate 26 and generates a high frequency magnetic field to inductively heat the pan 27. The temperature detector 29 detects the lower temperature of the top plate 26 and outputs the detected temperature to the input control means 32. The user inputs the setting of cooking at the switch section 30, and the result is output to the input control means 32 and the control means. 31 controls the heating coil 28 and also determines whether the pot 27 is appropriate for induction heating by the signal input from the input determination means 38 via the output control means 35, or the presence or absence of the pot 27, and the input control means 32. The input control means 32 outputs a signal corresponding to the temperature of the temperature detector 29, the setting of the switch unit 30 and the state of the pot of the control means 31 to the input determination means 33, The determination unit 33 determines the output of the input control unit 32 and outputs the output to the output control unit 35, the voice synthesis unit 34, and the display unit 44. The voice synthesis unit 34 outputs the determination signal from the input determination unit 33. The voice control unit 35 outputs voice data, the output control unit 35 outputs a determination signal to the control unit 31 based on the output of the input determination unit 33, the control unit 31 controls the heating coil 28 based on the determination signal, and the voice synthesis LSI 36 performs voice synthesis. The voice data is input from the means 34 and a voice signal is output. The oscillator 37 generates a clock for the voice synthesis LSI. The amplifier (AMP) unit 38 amplifies the voice signal output from the voice synthesis LSI 36. The signal from the amplifier unit 38 is converted into sound and output, and the display unit 44 is configured to light up and display an LED according to the output of the input determination means 33. The voice synthesizing unit 34 outputs voice data based on the output signal of the input determining unit 33 such as a state where the switch unit 30 is operated, the pan 27 is not appropriate, or the temperature detector 29 detects a dangerous temperature. At the same time, the LED of the display unit 44 is turned on based on the output signal of the input determination means 33 (see, for example, Patent Document 1).

In addition, if another sound or notification sound is generated during playback of a warning sound or notification sound in the case of an incorrect use of equipment in a heating cooker or abnormality, before listening to the sound or notification sound being played back It was interrupted, priority was given to later voices and notification sounds, and the user could miss information from the device. As countermeasures, there have been some that point out misuse or warn of abnormalities by display means such as LCD and LED in parallel with voice notification (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 1-130296 JP 2001-17319 A

  However, the conventional configuration has not solved the problem that a user may miss information from a device when multiple notifications are overlapped at the same time. There has been a problem that the role of notification, such as support by a guide or the like or notifying the user of a change in the device, cannot be sufficiently fulfilled even when the device is out of reach.

  The present invention solves the above-described conventional problem, and when the conditions for generating a plurality of notifications at the same time overlap, the notification that should be notified immediately or the notification that should not be interrupted in the middle or interrupted in the middle It is an object of the present invention to provide a heating cooker that can play a role of notification by determining whether or not the notification is possible and changing the notification timing, thereby improving the usability.

  In order to solve the above-described conventional problems, the cooking device of the present invention includes a reproduction method determination unit that determines a reproduction method of voice or notification sound based on a signal from a control unit or a signal from an input unit, and is currently informing. When there is a signal for notifying the next sound or notification sound from the input means or the control means when there is a voice or notification sound or when there is a plan to immediately notify the sound or notification sound, One optimum reproduction method can be selected from the reproduction methods.

  Accordingly, it is possible to prevent the user from being confused due to missed listening to the explanation of the operation of the device, the automatic cooking end notification, and the warning at the time of abnormality.

  The heating cooker of the present invention can reliably transmit notification from the device to the user, further improve the convenience and safety effects by voice notification, and improve usability.

  The first invention is a heating means for heating an object to be heated, an input means for allowing the user to select whether or not the heating means is energized, and energizing the heating means in response to a signal from the input means. A control unit for controlling, a playback method determining unit for determining a playback method of a sound or a notification sound based on a signal from the control unit or a signal from the input unit, and a voice or notification according to a signal from the playback method determining unit A voice synthesizing unit that outputs a sound, and the reproduction method determining unit is configured to notify the next voice or notification sound when there is a currently notified voice or notification sound or when there is a plan to immediately notify the voice or notification sound. When a signal for informing the user is received from the input means or the control means, by selecting one reproduction method from a plurality of reproduction methods, a voice that does not need to be immediately notified, such as an automatic cooking end notification, As for the sound, the sound that is currently being notified and the notification sound are notified. Important sound and notification sounds such as a warning in case of abnormality are not interrupted if it is currently being notified, and another sound or notification sound is notified. If it is in the middle, the optimal playback method is selected, such as interrupting and giving priority to the notification, so the effects of voice and notification sound can be fully exerted, preventing confusion due to user operation and ease of use of the device Can be improved.

  In the second invention, in particular, the optimum reproduction method according to the sound or the notification sound is selected by uniquely determining the reproduction method of the first invention according to each sound or the notification sound. Since the effect of the notification sound can be sufficiently exhibited, confusion due to the user's operation can be prevented, and the usability of the device can be improved.

  In particular, the third aspect of the invention uniquely determines the playback method of the first aspect of the invention in accordance with a combination of a voice or notification sound that is currently being reported or scheduled to be notified and a sound or notification sound that is to be notified next. As a result, the optimum playback method is selected according to the combination of the voice or notification sound currently being reported or scheduled to be notified and the voice or notification sound to be newly notified, so that the effects of the voice and the notification sound can be sufficiently exhibited. Therefore, it is possible to prevent confusion caused by the operation of the user and improve the usability of the device.

  In the fourth aspect of the invention, in particular, at least one of the playback methods in any one of the first to third aspects of the present invention temporarily interrupts a sound or a notification sound that is currently being reported or is scheduled to be notified. Then, by using the playback method of notifying the sound or notification sound to be notified next and then notifying the interrupted sound or notification sound again, the sound or notification sound that must be transmitted to the user, such as a warning at the time of abnormality, can be obtained. If the operation is interrupted by an interrupt notification sound of some operation during notification, the safety or usability of the device can be improved by notifying the interrupted sound or notification sound again.

  In a fifth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, when a plurality of notification means is provided and a method of simultaneously reporting a plurality of sounds or notification sounds is selected by the reproduction method determination means. By notifying each of the notification means of each voice or notification sound, the notification means are different even though they are generated at the same time, making it easier to hear each voice or notification sound and improving the usability of the device. Can be made.

  The sixth invention, in particular, includes a plurality of heating means according to any one of the first to fifth inventions, and a plurality of heating means can be used at the same time, so that a plurality of sounds and notification sounds can be generated simultaneously. However, the selection of an effective regeneration method by the regeneration method determination means is effective, and the usability of the multi-mouth cooking device can be further improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(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. In this embodiment, two induction heating cookers are taken as an example, and there are two pots a, b for the pan 2, the heating coil 3, and the temperature detector 4, respectively. The switch unit (input means) 5 inputs the setting and the result is input to the control means 6, the control means 6 controls the output of the heating coil 3, and the regeneration method determination means 7 is the switch part 5 or the control means. 6 determines the playback method of the voice data according to the command from 6, the voice synthesizer 8 outputs the voice data with the playback method according to the command from the playback method determination unit 7, and the voice synthesizer LSI 9 receives the voice synthesizer 8 from the voice synthesizer 8. The output audio data is input and an audio signal is output. The oscillator 10 generates a clock for the audio synthesis LSI 9, the amplifier (AMP) unit 11 amplifies the audio signal, and the notification unit 12 including a speaker is the amplifier unit 11. It is the structure which converts the signal from and outputs an audio | voice. In this case, the control means 6, the reproduction method determination means 7, and the speech synthesis means 8 are constituted by a microcomputer 13.

  FIG. 2 is a table showing the generation conditions and contents of sound or notification sound generated in the heating cooker according to the present embodiment, and each is indicated by a number from 14 to 18 respectively.

  FIG. 3 shows a program chart showing a determination method in the regeneration method determination means of the heating cooker in the present embodiment.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, after a power switch (not shown) is turned on, a start button for heating the pan 2-a is pressed in the switch unit 5. Since the input of the switch unit 5 is accepted, the 14 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 3 starts. In this case, since there is no voice or notification sound currently being notified, 22 is determined and a notification sound (pi) is notified. At the same time, the control means causes the heating coil 3-a to heat the pan 2-a by the start signal from the switch unit 5.

  Over time, the food in the pan 2-a has run out of water, and the temperature of the pan 2-a has become high. The temperature detector 4-a sends a signal to the control means 6 that the temperature is high. Since the temperature detector 4-a is detected, 17 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 3 starts. In this case, since there is no sound or notification sound currently being notified, 22 is determined, and the sound (the pot of a is empty) is notified. At the same time, the control means 6 interrupts the heating of the pan 2-a by the heating coil 3-a. While notifying the voice (the pan of a is empty), the start button for heating the pan 2-b is pressed in the switch unit 5. Since the input of the switch unit 5 is accepted, the 14 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 3 starts. In this case, the voice or notification sound currently being notified is 17 and the generated condition is 14, so 19 is determined. The voice (a's pan is baked empty) is temporarily interrupted, and a notification sound (pi) is notified. After that, the voice (a's pan is baked empty) is announced again.

  In addition, the heating time set for the pan 2-b that has been heated while reporting the voice (the pan of a is empty) has passed, and the heating of the pan 2-b by the heating coil 3-b is finished. Let's say that The fifteen generation conditions shown in FIG. 2 are established. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 3 starts. In this case, since the voice or notification sound currently being notified is 17 and the generation condition established is 16, 21 is determined. After notifying the sound (the pot of a is baked) to the end, the sound (heating of b is finished) is notified.

  Subsequently, an end button for ending the heating of the pan 2-a is pressed in the switch unit 5 while notifying the voice (b has been heated). Since the input of the switch unit 5 is accepted, the 14 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 3 starts. In this case, the currently notified voice or notification sound is 16, and the generated condition is 14, so that 20 is determined. The sound (heating of b is finished) is interrupted and a notification sound (pi) is notified.

  As described above, in the present embodiment, the dangerous temperature sound that the user should not miss, such as sound (the pot of a is baked) even when the conditions for simultaneously generating sound or notification sound are met, is the first. It is determined that the playback method is fully informed from the end to the end, and it is necessary to be notified at the time of occurrence of the notification sound (pi), such as the reception sound of the switch part. By determining the playback method to be notified, the notified voice and notification sound are effectively notified without a sense of incongruity, and the usability of the device is improved.

  Further, the same effect can be obtained when a heating unit such as a radial heater or a gas heat source is used instead of the heating coil 3 which is a multi-port of this embodiment, or even when the heat source is a single mouth.

  In this embodiment, the temperature detector 4 is provided to detect the dangerous temperature, and the dangerous temperature sound is notified. However, the pot is 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 obtained also in various sounds, such as when a dirt detecting unit is provided for detecting dirt on the top plate 1 based on the difference in the amount of infrared light input from above the top plate 1 and performing dirt detection voice processing. .

  In the present embodiment, the playback method is determined based on the combination of the currently notified voice or notification sound and the newly generated voice or notification sound generation condition. On the other hand, the same effect can be obtained even with a playback method that is uniquely determined for a playback method or a playback method that is uniquely determined according to the generation conditions of newly generated sound or notification sound.

  In the present embodiment, the notification means is constituted by a speaker, but the same effect can be obtained even if a buzzer is used.

  In the present embodiment, a method such as a method of simultaneously reproducing sound or notification sound by the reproduction method determination unit can be included in the determination unit. In that case, it may be performed by a plurality of notification means, or a plurality of voices or notification sounds may be synthesized inside the voice LSI and generated simultaneously by one notification means.

(Embodiment 2)
FIG. 4 is an overall configuration diagram of a heating cooker according to the second embodiment of the present invention. The second amplifier (AMP) unit 23 amplifies the second audio signal, and the second notification unit 24 including a speaker is configured to convert the signal from the second amplifier unit 23 and output the audio.

  The difference from the first embodiment is that a second amplifier (AMP) unit 23 and a second notification unit 24 are provided.

  FIG. 5 is a program chart showing a determination method in the regeneration method determination means of the heating cooker in the present embodiment.

  Hereinafter, the operation of the cooking device according to the above configuration will be described with reference to the configuration shown in FIG. 4, the table of voice or notification sound to be notified shown in FIG. 2, and the program chart of the reproduction method determination means 7 shown in FIG. 5.

  First, after a power switch (not shown) is turned on, a start button for heating the pan 2-a is pressed in the switch unit 5. Since the input of the switch unit 5 is accepted, the 14 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 5 starts. In this case, since there is no voice or notification sound currently being notified, 22 is determined and a notification sound (pi) is notified. This notification is performed by the second notification means 23. At the same time, the control means causes the heating coil 3-a to heat the pan 2-a by the start signal from the switch unit 5.

  It is assumed that the heating time set for the pan 2-a has elapsed and the heating of the pan 2-a by the heating coil 3-a is to be finished. The fifteen generation conditions shown in FIG. 2 are established. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 5 is started, and since there is no sound or notification sound currently being notified, 22 is determined and the sound (heating of a is finished) is notified. . This notification is performed by the notification means 12. While notifying the voice (the heating of a is finished), the end button for ending the heating of the pan 2-b is pressed in the switch unit 5. Since the input of the switch unit 5 is accepted, the 14 generation conditions shown in FIG. 2 are satisfied. At that time, the program chart of the reproduction method determination means 7 shown in FIG. 5 starts. In this case, the currently notified voice or notification sound is 15, and the generated condition is 14, so 25 is determined. While notifying the sound (the heating of b is finished) by the notifying means 12, the notifying sound (pi) is simultaneously notified by the second notifying means 23.

  As described above, in the present embodiment, when a predetermined time counted by the plurality of timing units 27 elapses, the signal transmitted from the control unit 6 stored in the speech synthesis LSI 9 to the speech synthesis unit 8 is deleted. Thus, when the user mistakenly performs the playback operation, the user may be confused because the voice before the predetermined time is notified to the user, for example, the notification content is different from the current state. In addition, by providing the display means 28 for displaying that voice is stored in the voice synthesizing LSI 9, it is possible to confirm the presence or absence of voice notification while the user is away from the device, and the usability of the device Will improve.

  In the present embodiment, the notification means is constituted by a speaker, but the same effect can be obtained even if a buzzer is used.

  As described above, since the cooking device according to the present invention can select and notify the optimal reproduction method when a plurality of sounds and notification sounds overlap, various types of sounds that use sound are not limited to cooking devices. It can also be applied to notification applications such as devices.
