Description

DETAILED DESCRIPTION OF THE INVENTION Recently, microwave ovens have become popular, in which complicated heating sequences can be programmed using microcomputers and cooking can be performed using the optimum heating sequence. However, as the heating sequence becomes more complex, it has the advantage of allowing more detailed cooking, but has the disadvantage of requiring more key operations, making it less user-friendly. In particular, it is necessary to confirm whether the key operation is correct by looking at the display corresponding to the key input content, so it takes time to set the heating sequence, and in the worst case, it may result in incorrect settings. It is also possible that it was lost when it was put away. In addition, since the time spent cooking in ordinary households is relatively small, there is a desire for a heating device that can be added with other appliances and is convenient in daily life.

The present invention uses such speech synthesis technology to

In an AND circuit, the ripple signal CP from the commercial power supply that serves as a count base for time, timer, etc. from the main controller 15 and the door signal that detects the opening and closing of the door.
This is for synchronizing DOOR, busy signal BSY indicating that audio is being generated, etc. Reference numeral 25 represents an oscillation time constant circuit and an initial reset circuit for the main controller 15. Note that the heating device and its configuration and circuit for detecting opening/closing of the door are well known, and detailed explanations thereof will be omitted.

Next, to explain the operation of the above configuration, the main controller 15 operates various functions based on the contents of the control program registered in advance in the program memory, and also operates the main controller 15 based on the contents of the control program registered in advance in the program memory. A predetermined heating sequence is executed depending on the conditions.

For voice synthesis, an output port is used from the main control device 15 to specify which voice to synthesize.
When the 5-bit audio address signals ω ₀ to ω ₄ output from R ₁₁ to _{R 15} and the audio strobe signal STR from the output port R ₇ are input to the audio controller 20, the audio controller 20 synthesizes the specified audio. A predetermined area in the audio data storage device 19 in which the audio to be played is stored in advance is accessed, and the necessary audio data is extracted. Next, the extracted audio data is output to the audio synthesis means 21 to synthesize the audio signal _V0 . When a key of the key input means 5 is pressed, a voice address signal ω ₀ to ω ₄ is generated, for example (0, 1, 1,
1, 1) is specified. By pressing the key, the output port R ₁₁ of the main controller 15
_R15 is set to (0,1,1,1,1), and then an audio strobe signal is output from output port _R7 .
When the STR is output, the audio controller 20 receives the information, returns a BSY signal to the main controller 15, and retrieves audio data of the "pi" sound from the audio data storage device 19. When the voice synthesis task is completed, the BSY signal is dropped and the next voice address signal and voice strobe signal are accepted. The timing chart when synthesizing this "pi" sound is shown in FIG. 4. Next, when a signal is received from the external signal input means 11a, 11b, 11c, the signal is given to the K input port of the main controller 15 in the same manner as described above, and the audio address corresponding to the external signal is sent to the audio controller 20. , utter a voice. Furthermore, this sound is transmitted to external sound notification units 12A, 12B installed in other rooms,
12C.

As an example of this, for example, the external signal input means 11
If any one of a, 11b, and 11c is used as the entrance chime, the audio data may be set to "We are a visitor" and the audio data corresponding to this may be registered. The transfer operation can be performed by operating the selection key of the key input means 5 that corresponds to the audio notification section to which the transfer is desired. The information is given to the K input port of the main control device 15 via the encoder 13, and inside the main control device 15, the data to generate the voice “I am a visitor” corresponding to the external signal is sent to the voice controller 20. At the same time, the external audio notification section 12A, 12B, 12C outputs a switching output.
Reed relays 9A, 9B, 9 compatible with key input
Drive either C. In this way, by simply operating the keys, it is possible to convert the external signal into audio and provide information to the external audio notification section.

Note that the audio controller 20 can be realized by a dedicated LSI made of hard logic or by another microcomputer. Audio data storage device 1
9 consists of a mask ROM. Speech synthesis means 21
is a dedicated LSI. In addition, since the audio signal V ₀ is a step-like composite waveform, it contains many high frequency components and is difficult to hear as it is, so the filter amplifier circuit 22 removes unnecessary high frequency components to improve the sound quality. It's on.

As is clear from the above description, the heating device of the present invention provides the following effects.

1. Since the sound corresponding to the operation key is emitted from the device, the user can judge by ear whether the key operation is correct or not, and erroneous operation is greatly reduced.

2. By simply operating a key, the contents of the external signal can be transmitted again in voice form to another voice notification section, eliminating the need for a circuit such as an intercom.

3. It can be realized with an extremely simple circuit configuration and has great effects such as ease of use.
