Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device having a voice generating mechanism, a control mechanism, and an operating section thereof.

If we look at conventional heating devices, such as microwave ovens, we find that they heat at a constant output for a certain period of time, such as when reheating or defrosting, or when they first heat at a high output and then at a low output, such as when boiling food. Furthermore, there are heating patterns that change the output and time each time, such as when adding ingredients, seasonings, or water or stirring ingredients during heating. In addition, in recent years, devices that directly or indirectly detect the temperature of the heated object and perform automatic control have been put on the market, and sequence control of the automatic control mechanism and the timer control mechanism has come to be performed. On the other hand, sequence control is performed by continuous heating or simultaneous heating of heating mechanisms, as seen in so-called microwave ovens that combine electric heater heating mechanisms, gas heating mechanisms, steam heating mechanisms, and the like.

As described above, heating devices have become increasingly multi-functional, but at the same time, they have also become complicated to operate, often resulting in malfunctions. The reason for this is that as the number of functions increases, the number of selection switches increases, or the switch functions differ depending on the procedure for pressing the same switch.

Another usability problem is the handling of intermediate progress. In other words, in order to know the progress of heating the object to be heated and the future heating schedule (including the end schedule), it is necessary to constantly check the timer, display lamp, etc., or check the status of the food from the window. . Furthermore, when the heating device does not operate normally, such as when a safety device is activated or a malfunction occurs, there is a problem that the user is confused because the reason cannot be determined. However, if a buzzer or the like is frequently used to solve these problems, it is easy to misidentify the tone or misinterpret instructions from other devices, resulting in many practical problems.

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art, and to solve the problem of proper operation, erroneous operation, and
Information on the progress of heating, scheduled heating progress, completion of heating, when to add ingredients, seasonings, or water during heating, when to stir the heated items, as well as instructions, as well as when safety devices are activated, when a malfunction occurs, etc. Furthermore, it is an object of the present invention to provide a heating device that is easier to use by providing audio notification when an accident (disaster) occurs.

In order to achieve the above object, the present invention provides a sound generation mechanism. Further, a control mechanism for controlling the heating mechanism and the sound generating mechanism, and an operation section for setting the operation of the control mechanism are provided, so that notification by sound is performed under predetermined conditions.

Hereinafter, the present invention will be specifically explained using the drawings. FIG. 1 is an embodiment of the present invention, and shows a configuration diagram of a heating device. In the figure, 1 is a heating chamber, 2

First, the outline of this heating device will be explained with reference to FIG. Now, when the door 4 is opened and the object to be heated 3 is placed on the saucer 2, when the user closes the door 4 and operates (inputs) the switch of the input/output device 18 on the panel, the control device 17 In response to the switch input, the operation contents are displayed on a fluorescent display tube (not shown) of the input/output device 18, and the user is notified by voice through the speaker 15. The contents of this audio notification vary depending on the input switch, but firstly, the contents of the switch are confirmed, secondly, instructions on how to operate (input) the switch, and thirdly, a warning of erroneous operation. Furthermore, when the specified switch is input,
At the start of heating, a series of switch input contents are notified in order to confirm the entire input switch. (These operations will be described in detail later.) Now, when a predetermined switch is input, heating finally begins, but in the heating device of this embodiment, the temperature of the object to be heated 3 is indirectly There is an automatic control system that determines the heating time by detecting the heating time, and a manual control system that determines the heating time using a timer, so I will explain the outline one by one here. However, the explanation regarding the fluorescent display tube will be omitted. It may be helpful to refer to Hitachi's microwave oven MR-8000A as a heating device of this type. First, we will discuss the case of automatic control method. This automatic control method utilizes the phenomenon that when the object to be heated 3 is heated and its temperature rises, the temperature of the air around the object to be heated 3 similarly rises. Specifically, air is sent into the heating chamber 1 from the air outlet 11 by the fan 6, this air is set to pass around the object to be heated 3, and this air is sent from the exhaust port 12 into the heating chamber 1. discharge outside. When the temperature of this discharged air (hereinafter referred to as exhaust temperature) is detected by the temperature sensor 7, the increase in the exhaust temperature after the start of heating corresponds linearly to the increase in the temperature of the object to be heated 3. When the temperature of the heated object 3 reaches around 100° C., the heated object 3 generates a large amount of water vapor, so that the exhaust temperature rises rapidly. Thereafter, the exhaust gas temperature becomes saturated (with fluctuations), and as time passes, the heated object 3 carbonizes and emits smoke, and eventually ignites, so the exhaust gas temperature rises to an abnormally high temperature.
Therefore, by storing the exhaust gas temperature at the start of heating or at the initial stage of heating, and comparing the exhaust gas temperature during heating with the stored exhaust gas temperature, the increase value of the exhaust gas temperature is detected, and the increase value of the exhaust gas temperature is Therefore, by controlling the heating, the temperature of the object to be heated 3 can be indirectly controlled. In addition, in this control method, two safety measures described below are implemented. The first step is to set the automatically controllable range.
When heating is repeated many times, the temperature of the wall surface of the heating chamber 1, the saucer 2, etc. becomes high (about 60 degrees Celsius), and the memorized exhaust temperature also becomes high. It becomes relatively small compared to the temperature rise value of . To compensate for this, heating is controlled in such a way that the higher the level of exhaust gas temperature, the smaller the increase in exhaust gas temperature, but this has its limits.
Therefore, when the exhaust gas temperature is above a predetermined level, heating is not started or heating is stopped. Second, the automatically controlled heating time is limited. Depending on the heating conditions, the increase in exhaust gas temperature may reach saturation at a level lower than normal. Therefore, in automatic heating control, the time required for heating is usually determined experimentally with respect to the output and used as the control time. For example, if the output is 600W, it will take about 15 minutes. If settings for heating using such an automatic control method are input from the input/output device 18, and a heating start setting is further input, the control device 17 causes the speaker 15 to generate sound, and accordingly sends a signal to the power supply device 16. send. The power supply device 16 receives a signal from the control device 17 and operates a high frequency oscillation tube 5, a fan 6, a motor 8,
Drive the lamp 10. The high-frequency oscillation tube 5 is driven by the power supply device 16 to oscillate, and supplies high-frequency power to the object 3 to be heated. The object to be heated 3 begins to be heated by the high frequency power. Note that the object to be heated 3 is rotated by the motor 8 and the saucer 2 and heated uniformly. Further, since the lamp 10 is lit, the heating status of the object to be heated 3 can be clearly seen from the viewfinder of the door 4. At the same time, wind is generated by operating the fan 6, but this wind is branched into two parts, one is the high frequency oscillation tube 5 and the other is the lamp 10.
is cooled and discharged to the outside, and the other enters the heating chamber 1 through the air outlet 11 provided near the door 4.
The steam (including water vapor) in the heating chamber passes near the object to be heated 3 and is discharged from the exhaust port 12 while preventing the findar of the door 4 from being clouded by the steam generated from the object to be heated 3. A temperature sensor 7 provided near the exhaust port 12 detects the exhaust temperature and sends a signal to the control device 17. The control device 17 immediately sends a signal to the power supply device 16 if the exhaust gas temperature is above a predetermined level. The power supply device 16 stops driving the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10, and returns them to the state before the start of heating. At the same time,
The control device 17 issues a warning through the speaker 15 that "the temperature in the heating chamber is high and automatic control is not possible." If the exhaust gas temperature is below a predetermined level, the control device 17 stores the exhaust gas temperature at this point in time, detects the increased value of the exhaust gas temperature, starts heating control, and starts counting the heating limit time.
As a reminder, these actions were performed in an extremely short period of time.

Heating progresses while the exhaust gas temperature is below a predetermined level, and as the temperature of the heated object 3 gradually rises, the exhaust gas temperature also rises. The control device 17 compares the exhaust gas temperature during heating with the stored exhaust gas temperature to determine the increase value of the exhaust gas temperature, and attempts to continue heating by automatic control until this increase value reaches a preset value. Even in this state, when the exhaust gas temperature reaches a predetermined level or higher, a warning is issued in the same manner as described above and the state returns to the state before heating started. Further, when the heating time limit is reached, the control device 17 notifies the speaker 15 that "the automatic control time limit has been reached" and sends a signal to the power supply device 16. The power supply device 16 stops driving the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10, and returns them to the state before the start of heating. When heating progresses while satisfying the conditions of setting the automatically controllable range and limiting the automatically controlled heating time, the exhaust temperature rise value eventually reaches the preset value, but when the set value is reached, The heating device operates according to the following three operations depending on the operation (input) of the input/output device 18 before heating starts.
There are two cases.

The first case is when heating is terminated. In this case, the control device 17 sends a signal to the power supply device 16,
The power supply device 16 receives this signal and stops driving the high frequency oscillation tube 5, fan 6, motor 8, and lamp 10. Therefore, the heating of the object to be heated 3 ends, and at this time, the control device 17 sends a signal to the speaker 15 to make it emit a sound unique to this heating pattern. In other words, notifications are made such as ``It has been heated to standard'' or ``It has been boiled.'' Note that at this point, the heating device is reset to the state before the input/output device 18 was operated.

The second case is a case in which heating is performed by adding a predetermined percentage of the time required for the increase value of the exhaust gas temperature to reach a preset value. Note that the additional time is calculated from the count value of the heating limit time. In this case, the control device 17 starts counting the additional heating time when the increase value of the exhaust gas temperature reaches a preset value. When the heating of the object 3 to be heated further progresses and reaches 1 minute before the end of the additional heating, the control device 17 sends a signal to the speaker 15 and warns the end of heating, saying, "Heating will end in 1 minute." utter. When another minute has passed, the control device 17 sends a signal to the power supply device 16, and the power supply device 16 receives this signal and stops driving the high frequency oscillation tube 5, fan 6, motor 8, and lamp 10. Therefore, the heating of the object to be heated 3 ends, and at this time, the control device 17 sends a signal to the speaker 15 to make it emit a sound unique to this heating pattern. In other words, the notification is made by saying something like, "It's been eaten." At this point, the heating device is reset to the state before the input/output device 18 was operated.

The third case is when additional heating is performed using a combination of high frequency output and heating time set in advance. In this case, the control device 17 sends a signal to the speaker 15, "Please put the ingredients in," when the exhaust temperature rise value reaches a preset value.
At the same time, a signal is sent to the power supply device 16 to start counting the heating time. The power supply device 16 changes the degree of drive of the high frequency oscillation tube 5 in response to a signal from the control device 17. The high frequency oscillator tube 5 changes the supply of high frequency power. Here, when the user opens the door 4, the door switch 19 (details of the function will be described later).
The control device 17 receives the signal, temporarily stops counting the heating time, and sends a signal to the power supply device 16. The power supply device 16 receives this signal and temporarily stops driving the high frequency oscillation tube 5. Therefore,
Heating of the object to be heated 3 is temporarily stopped. Then, when the user adds ingredients and closes the door 4, the control device 17 receives the signal from the door switch 19 again, starts counting the heating time again, and sends a signal to the power supply device 16. The power supply device 16 receives this signal and starts driving the high frequency oscillation tube again. Heating of the object to be heated 3 is started again. In addition,
If the door 4 is not opened and the object to be heated is not added, the object to be heated 3 will continue to be heated. The heating of the object to be heated 3 further progresses and reaches one minute before the end of heating, that is, one minute before the predetermined heating time due to a change in the supply of high frequency power. The control device 17 sends a signal to the speaker 15 to make the speaker 15 emit a notice of the end of heating, such as "Heating will end in one minute." After another minute has passed, the control device 17 controls the power supply device 1.
6, and the power supply device 16 receives this signal and stops driving the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10. Therefore, the heating of the object to be heated 3 ends, and at this time, the control device 17 sends a signal to the speaker 15 to make it emit a sound unique to this heating pattern. In other words, it is notified such as "It's cooked."
At this point, the heating device is input/output device 1.
8 is reset to the state before it was operated. Automatic control is performed as described above.

Next, the case of the manual control method will be described. Note that this manual control method is achieved by the user setting the combination of high frequency output and heating time in advance, and in the heating device of the present invention, it is possible to set up to two stages. If heating settings using such a manual control method are input from the input/output device 18 and heating start settings are further input, the control device 17 causes the speaker 15 to emit the above-mentioned sound, and accordingly turns off the power. device 16
and start counting the heating time. The power supply device 16 receives signals from the control device 17 and drives the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10. The high frequency oscillation tube 5 is the power supply device 1
6 to oscillate and send high frequency power to the heated object 3.
supply to. The object to be heated 3 begins to be heated by the high frequency power. Note that the object to be heated 3 is rotated by the motor 8 and the saucer 2, and is heated almost uniformly. Further, since the lamp 10 is lit, the heating status of the object to be heated 3 can be clearly seen from the viewfinder of the door 4. At the same time, wind is generated by the operation of the fan 6, but this wind is branched into two parts, one of which cools the high-frequency oscillation tube 5 and the lamp 10 and is discharged to the outside, and the other part of the wind that cools the high-frequency oscillation tube 5 and the lamp 10 and is discharged to the outside. The air enters the heating chamber 1 through the air outlet 11 provided nearby, passes near the object 3 to be heated, and enters the heating chamber while preventing the window 4 of the door 4 from being clouded by steam generated from the object 3 to be heated. The steam (including water vapor) is discharged from the exhaust port 12. This discharged air passes around the temperature sensor 7 provided near the exhaust port 12 and is discharged to the outside. It should be noted that these operations are performed in an extremely short period of time. In this way, heating starts and progresses,
As for the operation of the heating device after this, there are two cases described below depending on the operation (input) of the input/output device 18 before the start of heating.

The first case is when heating is terminated when the heating time count reaches a predetermined time. In this case, one minute before heating ends, the control device 17 sends a signal to the speaker 15,
Finish heating after a minute. ” to announce the end of heating. After another minute has passed, the control device 17
sends a signal to the power supply device 16, and the power supply device 16 receives this signal and stops driving the high frequency oscillation tube 5, fan 6, motor 8, and lamp 10. Therefore, the heating of the object to be heated 3 ends, and at this time, the control device 17 sends a signal to the speaker 15 to notify the end of heating. In other words, it notifies that "heating has been completed." At this point, the heating device is reset to the state before the input/output device 18 was operated.

The second case is when another combination of high frequency output and heating time is executed when the heating time count reaches a predetermined time. In this case, when the predetermined time described above is reached, the control device 17 sends a signal to the speaker 15, saying "Step 2,""Output200W," and "Heating time is 20 minutes." It notifies the progress and also sends a signal to the power supply device 16. Power supply device 16
receives this signal and changes the degree of drive of the high frequency oscillation tube 5. This changes the supply of high-frequency power, and the degree of heating of the object to be heated 3 changes.
At the same time, the control device 17 resets the heating time count described above and starts counting the second stage heating time. In this way, the second stage of heating is started, and as the heating progresses further, the first stage of heating ends.
The control device 17 sends a signal to the speaker 15 one minute before the end of the heating period, and causes the speaker 15 to emit a warning that the heating will end in one minute. When another minute has passed, the control device 17 sends a signal to the power supply device 16, and the power supply device 16 receives this signal and stops driving the high frequency oscillation tube 5, fan 6, motor 8, and lamp 10. Therefore, the heating of the object to be heated 3 ends, and at this time, the control device 17 sends a signal to the speaker 15 to notify the end of heating. That is,
Notify that "Heating has finished." Note that at this point, the heating device is reset to the state before the input/output device 18 was operated. As described above, the manual control method operates.

Next, operations common to the automatic control method and manual control method will be described. In order to avoid complication in the above-mentioned explanations of the automatic control method and manual control method, we will explain the operation in the event of a failure of the heating mechanism such as the high-frequency oscillation tube 5 and the power supply device 16 during heating, and the heated object. No mention was made of the actions in the event of an ignition (fire) accident in item 3. We will explain these in turn. Note that the operation (input) of the input/output device 18 and the door 4 during heating
Although the operation of the door switch 19 accompanying the opening and closing of the door switch 19 is not described, these will be explained in detail later along with the operations before starting heating.

The relationship between the exhaust gas temperature and the temperature of the object to be heated 3 was described above, and this makes it possible to detect failures in the heating mechanism such as the high frequency oscillation tube 5 and accidents such as ignition of the object to be heated 3. can. First, regarding the malfunction of the heating mechanism, when the high frequency oscillation tube 5 etc. are operating normally, the object to be heated 3 is heated and the air (wind) around the object to be heated 3 is heated. Since this is discharged (flows out), the exhaust gas temperature after a certain period of time from the start of heating rises from the temperature at the start of heating. Therefore, conversely, if the temperature does not rise or if the temperature falls, high frequency power is not being supplied. For this reason, the control device 17
determines the increase value of the exhaust gas temperature after a certain period of time (preferably about 2 minutes) has elapsed from the start of heating, and if it has not increased, sends a signal to the speaker 15,
At the same time, a signal is issued to the power supply device 16 to stop the drive of the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10. At this point, the heating device is reset to the state before the input/output device 18 was operated. Similarly, it is possible to warn of an accidental ignition of the heated object 3. In other words, in automatic control or manual control, there is a risk of ignition when a heated object 3 with a low moisture content, such as moist potato chips, is heated and dried for a relatively long period of time. In some cases, the exhaust temperature rises rapidly and to very high temperatures. Therefore, ignition can be detected based on the detection signal from the temperature sensor 7. In this case, the control device 17 sends a signal to the speaker 15 to issue an alarm saying "Fire accident has occurred." This warning has a higher volume and a faster sounding speed than other sounds, and is repeated five times. At the same time, a signal is sent to the power supply device 16, and the high frequency oscillation tube 5,
The driving of the fan 6, motor 8, and lamp 10 is stopped. At this point, the heating device is reset to the state before input/output device 18 was operated.

In addition, in detecting ignition accidents, the same performance as in the case of the exhaust gas temperature rise value could be obtained even when using the absolute value of the exhaust gas temperature or using the relative value with respect to the ambient temperature of the heating device.

Next, the operation of the input/output device 18 shown in FIG. 1 will be specifically explained. FIG. 2 is a diagram showing in detail one embodiment of the input/output device 18 shown in FIG.

Also, 28 is the numerical value "1" and the automatic warming (high) setting switch, 29 is the numerical value "2" and the automatic warming (standard) setting switch, 30 is the numerical value "3" and the automatic warming (low) setting switch, and 31 is the numerical value "4" ” and the automatic boiling setting switch, 32 is the numerical value “5” and the automatic boiling setting switch, 33 is the numerical value “6” and the automatic boiling setting switch, 34 is the numerical value “7” and the automatic boiling setting switch, 35 is the numerical value “8” and the automatic boiling setting switch. This is an automatic stew (for stew) setting switch. These numbers 28 to 35 and the automatic setting switch are set according to the operating procedure, that is, these 2 numbers.
The functions differ depending on whether the switches 8 to 35 are input for the first time, the second time, or in any other order. (The specific procedure will be described later.) In the case of a numerical setting function, it is used to specify the heating time and clock time in an automatic control system. The automatic setting, that is, the heating setting using the automatic control method is as follows. In other words, automatic heating (high)
When the setting switch 28 is input, the function is to heat the heated object 3 with a high frequency output of 600W, and stop heating when the heated object 3 reaches the exhaust temperature rise value setting of around 100℃. do. When the automatic warming (standard) setting switch 29 is input, the function is to heat the heated object 3 with a high frequency output of 600 W, and reach the exhaust temperature rise value setting where the heated object 3 is around 80 degrees Celsius. Finish heating at this point. When the automatic warming (lower) setting switch 30 is input, the function is to heat the heated object 3 with a high frequency output of 600W, and reach the exhaust temperature rise value setting where the heated object 3 is around 60℃. Finish heating at this point.
The function when the automatic boil setting switch 31 is input is the same as when the automatic warm (high) setting switch 28 is input. When the automatic insect setting switch 32 is input, the function is high frequency output.
The object to be heated 3 is heated by 600W, and the object to be heated 3 is
When the exhaust gas temperature rise value reaches the set value where the temperature is around 100°C, additional heating is performed for a predetermined percentage of the heating time required up to that point. When the automatic boil setting switch 33 is input, the function is high frequency output.
The object to be heated 3 is heated by 600W, and the object to be heated 3 is
When the temperature reaches the set exhaust temperature rise value of around 100℃, the high frequency output is changed to 200W and additional heating is performed for a predetermined period of time. The function when the automatic simmer setting switch 34 is input is the same as when the automatic simmer setting switch 33 is input, except that the additional heating time is lengthened. Automatic stew (for stew) setting switch 3
The function when 5 is input is the same as when the automatic simmering setting switch 34 is input, but the additional heating time is made longer. Next, 36 is a numerical value "9" setting switch, and 37 is a numerical value "0" setting switch. Numerical setting switch 3
Reference numerals 6 and 37 are used to specify numerical values as a numerical setting function and the automatic setting switches 28 to 35 to specify the heating time and clock time in a manual control system. 38 is a "start" switch for starting heating. After setting the automatic control method or the manual control method, when this "start" switch 38 is input, heating of the object to be heated 3 is started and time counting is started. 39 is a "stop" switch for stopping heating. This is a switch that becomes effective only during heating after the "start" switch 38 is input, and this "stop" switch 39
If inputted, the heating of the object to be heated 3 is stopped, and the time counting is stopped. 40 is a "clock" switch for the clock function. In this heating device, the time can be displayed on the fluorescent display tube 21 when the automatic control method or manual control method is being set and when heating is not being performed. “Clock” switch 4
0 is for setting the time and starting clock operation. 41 is a "repeat" switch for listening to the uttered voice again. By inputting this "repeat" switch 41, the group of messages before the input of the "repeat" switch 41 can be uttered again. Reference numeral 42 denotes a volume with a switch for setting whether to generate sound or not, and for adjusting the sound pressure level when voice generation is enabled. Note that the "repeat" switch 41 and the volume switch 42 are effective even during heating. 43 is a knob for a volume with a switch. 44 is “start”
This is a "cancel" switch that invalidates switch inputs other than switch 38, "stop" switch 39, and volume with switch 42.

Next, the operating procedures for the switches shown in FIG. 2 will be explained. FIG. 3 is a diagram showing an embodiment of a switch operation procedure for the input/output device 18 shown in FIG. 2. In FIG. 3, 50 is a numerical value and a single input "A ₁ " of automatic setting switches 28 to 35;

This is the input of the switch 40.

The basic operating procedure for heating using the automatic control method is a.
become that way. That is, first, select and input one of the numerical values and automatic setting switches 28 to 35 (input A ₁ 50). Next, the "start" switch 38 is used to input "start" 51. This will start heating using the automatic control method. Further, the modification or change of the switch input in a is as shown in b. That is, the input A ₁ 50 can be corrected each time by inputting the input A ₂ 52, the input A ₃ 53, and selecting one of the numerical values and automatic setting switches 28-37. Finally, input A _o 54 is entered and the "start" input 51 is activated by the function of input A _o 54 (described in FIG. 2) to begin heating. Moreover, if it is desired to stop the heating itself by the automatic control method, it is sufficient to enter a "cancel" input 55 after the input A _o 54. In this case, enter
It is reset to the state before A ₁ 50 was input.

Furthermore, the basic operating procedures for heating using the manual control method are as shown in c and d. c is heating in which the combination of high frequency output and heating time is only one time. d is two consecutive heatings. That is, in step c, first select and input one of the output setting switches 23 to 27 (input "output 1" 56). Next, select one from numeric and automatic setting switches 28 to 35 and numeric setting switches 36 and 37 and input "N ₁ "
Enter 57. (However, the maximum number of times is 4.) Note that this input "N ₁ " 57 corresponds to the heating time. After inputting the "output 1" 56 and N ₁ 57 in this way, the "start" input 51 is input.
This will start heating using the manual control method. In d, after inputting "output 1" 56 and N ₁ 57 of c,
Furthermore, input the combination of high frequency output and heating time,
The "start" input 51 is then entered. In other words, after inputting “output 1” 56 and N ₁ 57,
Furthermore, one of the output setting switches 23 to 27 is selected and "output 2" 58 is input. Next, one of the numerical and automatic setting switches 28 to 35 and the numerical setting switches 36 and 37 is selected and input "N ₂ " 59 is input. (However, up to 4 times.)
Note that this input "N ₂ " 59 also corresponds to the heating time like "N ₁ " 57. In this way “output 1” 5
6. By inputting “N ₁ ” 57, “output 2” 58 and “N ₂ ” 59 and then inputting the “start” input 51, heating by the two-stage manual control method is started. Also, correction of switch input in c and d,
The changes are as follows: e, f. That is, the input "output 1" 56 can be modified each time by selecting and inputting one of the input "output 2" 58 and the output setting switches 23 to 27 in sequence, as shown in e. Finally, enter the input "output n" 60, then select one from the numerical and automatic setting switches 28 to 25, and the numerical setting switches 36 and 37, and input the input "N ₁ " 57 (however, the maximum up to 4 times),
When the "start" input 51 is input, heating by the combination of the input "output n" 60 and the input N ₁ 57 is started. Note that the same applies to the modification of the input "output 2" 58 of d. Furthermore, if it is desired to stop heating using the manual control method, a "cancel" input 55 may be input in place of the "start" input 51.
In this case, the state is reset to the state before input "output 1" 56 was input. Furthermore, if you want to modify the combination of input "output 2" 58 and input N ₂ 59 in d, input N ₂ 5 of d as shown in f.
After 9, enter the "cancel" input 55, enter the new inputs "output 2" 58, input N ₂ 59, and enter the "start" input 51. Also, “cancellation”
If the "start" input 51 is entered immediately after the input 55 is entered, the result is the same as in c. If you wish to stop the manual heating itself, if you then input the "cancel" input 55 (input twice), the state will be reset to the state before the input "output 1" 56 was input.

Next, the heating stop operation will be described. As shown in g, when the "start" input 51 is input after the automatic control method or manual control method is set, heating starts. Then “stop”
When input 61 is entered, heating is stopped. To start heating again, it is sufficient to input the "start" input 51, and if it is desired to stop heating altogether, to input the "cancel" input 55, the automatic control method or manual control method is set. will be reset to the previous state.

Next, the settings for the voice production operation will be described. Regardless of whether before or after heating starts, if the switch of the volume with switch 42 is turned on (within the volume operating range), the input will be sent to the switch-on input 62.
This makes it possible to produce audio. However, it is always possible to issue audible warnings in the event of an accident. Note that by adjusting the volume of the volume with switch 42 using the knob 43, the sound pressure level of the audio can be changed (sliding it to the right increases the audio). Suppose that some sound is produced from the speaker 15 in this state. If the user wishes to make the voice sound again, he/she may input the "repeat" input 63. In this case, the group of messages before the input 63 is uttered again. In addition, if the switch of the volume with switch 42 is turned off (outside the volume operating range) while the voice is being produced or even when the voice is not being produced, the input will be transferred to the switch-off input 6.
4, and voice production becomes impossible. moreover,
When the "repeat" input 63 is input and the voice is being produced, if the "cancel" input 55 is input, the "repeat" input 63 becomes invalid and the voice production stops.

Next, the setting of the clock function will be described. If the "clock" switch 40 is input during settings of the automatic control method or manual control method or during heating, the "clock" input 65 is input, and the time can be set. Next, numerical value and automatic setting switches 28 to 35, numerical value setting switches 36 and 37
Select from among them and input "N ₁ " 57. Note that the input "N ₁ " 57 in this case corresponds to time and is input three or four times, and the first input must not be "0". Furthermore, when inputting four times, the first input must be "1". Furthermore, when the "clock" switch 40 is input, the "clock" input 65 is input again, and time counting starts from the value of the previous input "N ₁ " 57. a given time e.g. 12
At 1:00, 1:00, 2:00, etc., the control device 17 sends a signal to the speaker 15 to notify the time by voice. Note that although the time is displayed on the fluorescent display tube 21, a description thereof will be omitted. These modifications and changes are as follows. That is, if the user wishes to stop the setting of the clock function at the time when the first "clock" input 65 is input, the "cancel" input 55 is subsequently input. Furthermore, if the user wishes to change the time setting at the time when the input "N ₁ " 57 is input, the "cancel" input 55 is subsequently input. By this, the input “N ₁ ”
57 is reset to the state before input. Note that, other than the individual numerical inputs of the inputs "N ₁ " 57 and "N ₂ " 59, if the same switch is input twice or more in a row, this is ignored (no sound is produced).

Now, in FIG. 1, in response to the operation (input) of the input/output device 18, the speaker 15 confirms the contents of the switch, gives instructions on the switch operation procedure, and warns of erroneous operation.
It was also stated that a series of switch input contents would be announced by voice at the start of heating. Regarding this point, Figure 2,
This will be explained using FIG.

First, the case of confirming the contents of a switch will be described. The numerical values and automatic setting switches 28 to 35 shown in FIG. The values are input as settings of "1" to "8", and the numerical value setting switches 36 and 37 are inputted as settings of numerical values "9" and "0". Then, when the number is entered, it speaks out the value. That is, if the numerical setting switch 36
If ``9'' is input, ``9 (Kyuu)'' is uttered. Moreover, when the "cancel" switch 44 is input,
When the user utters ``Cancel'' and inputs the ``stop'' switch 39, the user utters ``Heating will be stopped'' to notify the contents of the switch.

Second, instructions for operating (inputting) the switch will be described. After inputting the output setting switches 23 to 27, normally, as shown in c and d of FIG.
7 inputs (“N ₁ ” 57, “N ₂ ” 59). Therefore, when the output setting switches 23 to 27 are input, an instruction can be given to set the heating time. If the output setting 600W switch 23 is input, after the switch contents are announced, such as "Output 600W." and "Please set the time."
The next operation instruction is uttered by voice.
In addition, when the numerical values and automatic setting switches 28 to 35 are input for the first time, that is, when the heating is set by the automatic control method, the subsequent inputs are normally ""Start" input 51. Therefore, an instruction can be given to input the start switch 38.
If the numerical value is "4" and the automatic boil setting switch 31
is input, ``I'll boil it.'' and ``Please press the start switch.'' are uttered. Furthermore, when the "clock" switch 40 is input for the first time, as shown in FIG.
37 inputs (“N ₁ ” 57). Therefore, it is possible to instruct the user to set the time. When the "clock" switch 40 is input for the first time, the operating procedure is instructed by voice, "Please set the time." In addition, in response to the second input of the "clock" switch 40 after the input "N ₁ " 57 is input, "the time has arrived" is notified for confirmation.

Third, let's talk about warnings for erroneous operations. Any operation procedure other than the one explained in FIG. 3 results in an erroneous operation. In such cases, by voice,
It issues a warning saying, "Operation error." For example, in Figure 3c, the input "output 1" 56
Assume that the "start" input 51 is input directly after inputting . At this time, the user utters "Operation error." and "Please set the time."

Finally, the notification of the contents of a series of switch inputs at the time of starting heating will be described. When a predetermined switch of the automatic control system or the manual control system is input and the "start" switch 38 is pressed, the "start" input 51 is input and heating and time counting begin. At this point, a series of switch input contents are reported in order to confirm the entire predetermined input switch. For example, in the operation shown in Fig. 3c, if the output setting 200W switch 26 is input, then the numerical value and automatic setting switches 28 and 29 are input, and the "start" switch 38 is pressed.
"Start heating.", "Output 200W.", "Time is 12
Seconds. ” is uttered out loud.

Next, the operation and function of the door switch 19 will be described here. As explained briefly in the heating by the automatic control method in Fig. 1, in the case of heating by high-frequency power, a door switch 19 is normally provided that turns on and off when the door 4 is opened and closed. High frequency oscillation tube 5 does not operate. This is for human safety and to prevent noise from being caused by other equipment. The heating device of the present invention is also provided with a door switch 19, and the door 4
is open, the OFF signal is sent to control device 1.
7, and if it is closed, an ON signal is sent to the control device 17. Before starting heating, perform the prescribed switch operation to turn on the "start" switch 38.
Even if you press (enter), if the door 4 is not completely closed, the control device 17 receives an OFF signal from the door switch 19 and does not send a signal to the power supply 16, so the high frequency oscillation tube 5 etc. are not driven, so heating does not start. Also, the control device 17 does not start counting time. At this point, that is, when the "start" switch 38 is pressed, the control device 17 sends a signal to the speaker 15 to issue a warning saying, "Since the door is not closed, there will be no heating." Furthermore, if the door 4 is opened during heating, the heating is stopped in the same way, and the user utters "Heating will be temporarily stopped." After that, when the door 4 is closed, "Heating will be resumed" is uttered. In addition, in the explanation of voice production in FIGS. 1 to 3 above, if a switch of the input/output device 18 (excluding the volume with switch 42) is operated during voice production, or if the control device 17 itself When a voice generation signal is output, the voice being generated is stopped and a new voice is generated.

Next, the configuration of the control device 17 shown in FIG. 1, the input/output device 18, the power supply device 16, etc. will be explained. FIG. 4 is a block diagram showing an example of the configuration of the input/output mechanism, control mechanism, and heating mechanism of the heating device shown in FIG. 1. Components in FIG. 4 that are the same as those in FIGS. 1 and 2 are designated by the same numbers. Reference numeral 70 is a microcomputer that forms the core of the control device 17 and includes a driver and the like. Specifically speaking, this microcomputer is manufactured by Hitachi.
It is a 4-bit microcomputer HMCS-45. 7
1 is a speech synthesis section, which is ICHD38880 manufactured by Hitachi, Ltd. and its peripheral circuits. 72 stores pre-analyzed voice data.
It is a ROM (read only memory), HD38881 manufactured by Hitachi, Ltd. however,
There are multiple HD38881s. 73 is a power amplification section. 74 is a volume portion of the volume 42 with a switch. In addition, volume 42 with switch
The switch section is included in the mechanical switch section 20. 75 is an interface section, specifically manufactured by Texas Instruments, USA.
TMS1976 and its peripheral circuits. Reference numeral 76 is an exhaust temperature detection section, which includes a thermistor used as the temperature sensor 7, a voltage division section for temperature voltage conversion (dividing a constant voltage by a resistor and a thermistor), and a positive phase amplification section (operational amplifier). It consists of a ladder resistor and a comparator for AD conversion. Reference numeral 77 is a clock signal generator, which controls the power supply frequency (50Hz or 50Hz) of this heating device.
It generates pulses from 60Hz). Specifically, it consists of a transformer, phase circuit, comparator, differentiator circuit, square wave generator, etc. Note that the power supply device 16 includes a triax, a relay, a transformer,
and a half-wave voltage doubler rectifier circuit (provided that a magnetron is used as the high-frequency oscillation tube 5). Further, arrows in the figure indicate the flow of signals.

These operations will be specifically explained using an example. Assuming that the heating device is now powered on, the microcomputer 70 starts operating and sends a scan (address designation) signal to the capacitive touch switch section 22, mechanical switch section 20, and fluorescent display tube 21 of the input/output device 18. Note that this operation is due to the dynamic drive. User is at door 4
When the door 4 is opened and the object to be heated 3 is placed on the saucer 2, the door 4 is closed, and the volume 42 with a switch included in the mechanical switch section 20 is turned on to set the volume section 74, the microcomputer 70 It receives the switch signal and prepares for voice production. Next, when the user inputs the automatic cooking setting switch 33 of the capacitive touch switch section 22, this input signal is sent to the interface section 75, and the interface section 75 converts the input signal into a 4-bit signal and converts it into a microcontroller. It is sent to computer 70. microcomputer 7
0 receives this automatic boiling setting signal and transmits data to the fluorescent display tube 21. The fluorescent display tube 21 receives this signal and performs a specific display. At the same time, the microcomputer 70 sends a signal to the speech synthesis section 71. The audio synthesis section 71 receives a signal from the microcomputer 70 and reads audio data from the ROM 72, synthesizes a predetermined audio signal according to the sound pressure level specified by the volume section 74, and sends it to the power amplification section 73. Send. The power amplifying section 73 amplifies the power of this synthesized audio signal,
Send to speaker 15. The speaker 15 receives the signal from the power amplifying section 73 and emits predetermined voices, ie, "I'll boil it." and "Please press the start switch." Next, when the start switch 38 of the mechanical switch section 20 is pressed, the microcomputer 70 receives a "start" input 51. On the other hand, the microcomputer 70 receives an on signal (door 4 closed) from the door switch 19 and a pulse signal from the clock signal generator 77. Therefore, when the microcomputer 70 receives the "start" input 51, it starts counting the time limit using the aforementioned pulse signal, and
Sends a signal to power supply 16. The power supply device 16 receives signals from the microcomputer 70 and drives the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10. Therefore, heating of the object to be heated 3 starts as explained in FIG. 1. At the same time, the speaker 15 generates the predetermined sounds "Heating will start" and "Simmer" in the same manner as described above. Further, the microcomputer 70 sends a signal (7-bit data, which corresponds to the sign of the temperature) to the exhaust temperature detection section 76. The exhaust temperature detection unit 76 processes the signal from the temperature sensor 7 and sends a digital temperature signal (“1” or “0”) to the microcomputer 70 in synchronization with the signal from the microcomputer 70. The microcomputer 70 determines the exhaust gas temperature from this digital temperature signal, stores the exhaust gas temperature at the start of heating or at the initial stage of heating, calculates the increase value of the exhaust gas temperature, and performs heating using an automatic control method. When the heating progresses and the exhaust temperature rise reaches a preset value, the microcomputer 70 resets the time limit count, starts counting the preset heating time, and displays the data on the fluorescent display tube 21. and sends a signal to the power supply 16. The fluorescent display tube 21 stops the above-mentioned specific display and displays the predetermined output and heating time. Note that this heating time display subtracts as time passes. Further, the power supply device 16 changes the degree of driving of the high frequency oscillation tube 5. Therefore, the high frequency output changes. At the same time, the microcomputer 70 sends a signal to the speech synthesis section 71.
In the same manner as described above, the speaker 15 emits a predetermined voice "Please put the ingredients in." Next, when the user opens the door 4, the door switch 19 is turned off (door 4
(opening) signal to the microcomputer 70.
The microcomputer 70 stops counting the heating time and sends data to the fluorescent display tube 21 to fix the heating time display. Further, a signal is sent to the power supply device 16 and the speech synthesis section 71. The power supply device 16 includes a high frequency oscillation tube 5, a fan 6, and a lamp 1.
0, the drive of the motor 8 is stopped. Heating therefore stops. On the other hand, the voice synthesis section 71 calls predetermined voice data from the ROM 72 as described above, drives the speaker 15 via the power amplification section 73, and causes the speaker 15 to say "Heating will be temporarily stopped." When the user adds the object to be heated 3 and closes the door 4, the door switch 19 sends an on (door close) signal to the microcomputer 70. The microcomputer 70 starts counting the heating time again, and sends data to the fluorescent display tube 21 to start displaying the elapsed heating time (remaining heating time). Further, a signal is sent to the power supply device 16 and the speech synthesis section 71. The power supply device 16 restarts heating, and the voice synthesis unit 71 causes the speaker 15 to utter a predetermined voice "Heating will resume." When the heating progresses further and reaches 1 minute before the predetermined heating time (the display on the fluorescent display tube 21 indicates 1 minute), the microcomputer 70
1, the speaker 15 is made to emit a predetermined voice saying "Heating will end in 1 minute." When one minute of heating time has elapsed, the microcomputer 70 sends a signal to the power supply device 16 and the audio synthesis section 71, and also sends a signal corresponding to a reset to the fluorescent display tube 21. Furthermore, the heating time count and the stored exhaust gas temperature are reset. The fluorescent display tube 21 stops displaying the output and time. The power supply device 16 receives a signal from the microcomputer 70 and stops driving the high frequency oscillation tube 5, the fan 6, the motor 8, and the lamp 10. Furthermore, the voice synthesis section 71 outputs the signal to the speaker 1 via the power amplification section 73.
5 to utter a predetermined voice, that is, "I boiled it." In this way, heating by the automatic control method is completed.

Another example of the operation of the block diagram of FIG. 4 will be described below. Now, the heating device is powered on and the microcomputer 70 starts operating.
a capacitive touch switch section 22 of the input/output device 18;
A scan (address designation) signal is sent to the mechanical switch section 20 and the fluorescent display tube 21. When the user turns on the switch of the volume 42 with a switch included in the mechanical switch section 20, the volume section 7 is turned on.
When set to 4, the microcomputer 70 receives the signal from this switch and prepares for voice production.

Next, at this point, the user turns on the capacitive touch switch section 2 to use the clock function of the heating device.
When the clock switch 40 of No. 2 is inputted, this input signal is inputted to the microcomputer 70 via the interface section 75. When the microcomputer 70 receives this clock setting signal, it determines that the signal is the first input, prepares to set the time, and sends a signal to the speech synthesis section 71. The voice synthesis section 71 receives a signal from the microcomputer 70 and drives the speaker 15 via the power amplification section 73. The speaker 15 emits a predetermined voice "Please set the time."
Next, a numerical value corresponding to the time, automatic setting switches 28 to 35, and numerical setting switch 3 are set.
When some of the numbers 6 and 37 are sequentially input to the microcomputer 70 as described above, a voice is produced in response to each input. For example, if you input the numerical values and automatic setting switches 28, 28, and 30 to set the time at 11:30, and then input the numerical value "0" to the setting switch 37, "1." and "1." will be displayed for each. The speaker 15 utters "San.""Zero." In addition, for each numerical value input, the microcomputer 70 sends data to the fluorescent display tube 21, and the fluorescent display tube 21 sequentially displays "1", "1", "3", and "0" ( The display at this point is “1130”.) Next, when the clock switch 40 is inputted again, this input signal is similarly inputted to the microcomputer 70 via the interface section 75. When the microcomputer 70 receives this clock setting signal, it determines that the signal is the second input and starts counting the time. Note that this count is performed by the microcomputer 70 counting pulses input from the clock signal generating section 77. At the same time, the microcomputer 70 sends a signal to the voice synthesis section 71 and data to the fluorescent display tube 21. The display at this point is "11:30". The voice synthesis section 71 sends a signal to the speaker 15 via the power amplification section 73, and the speaker 15 utters a predetermined voice "The time has arrived." Thereafter, the microcomputer 70 continues counting and sends data to the fluorescent display tube 21 at predetermined intervals to change the display. Note that the display of the heating time also operates in a similar manner. However, the hours, minutes, and seconds positions will be shifted. For example, "11.30" is 11 minutes and 30 seconds. The time advances to a specific time, for example 12 o'clock,
At 1 o'clock, 2 o'clock, etc., the microcomputer 70 determines that the last two digits are "00", calls the contents of the specific time mentioned above, and activates the speech synthesis section to generate the corresponding sound. Send a signal to 71. The voice synthesis section 71 retrieves voice data corresponding to the time from the ROM 72, performs voice synthesis, and causes the speaker 15 to output the time via the power amplification section 73. For example, say "It's 12 o'clock."

Next, the speech synthesis section 71, ROM 72, etc. will be briefly explained. Speech synthesis section 7 of the heating device of the present invention
In No. 1, a speech synthesis method based on the PARCOR method is used as a method for reproducing speech from speech characteristic parameters. Since the PARCOR method is already widely known in the speech research field, a detailed description will be omitted, but a brief explanation will be given below. First, the method of extracting voice feature parameters is
The PARCOR analysis method analyzes the original audio signal from 10 msec to 20 m
sec interval, and within this interval, calculate the partial autocorrelation coefficient (hereinafter referred to as PARCOR coefficient), which is a type of linear prediction coefficient that characterizes speech, and calculate the volume, pitch, and voiced sound ( This is to find the discrimination signal between vowels) and unvoiced sounds. Also, the audio
When regenerating using the PARCOR synthesis method, the
The playback sound is calculated from the PARCOR coefficient, volume, pitch, and voiced/unvoiced sound identification signal.
In other words, the ROM72 in Fig. 4 contains the
PARCOR coefficient determined by PARCOR analysis method,
It stores characteristic parameters consisting of volume, pitch, and identification signals between voiced and unvoiced sounds. In addition, in the case of this example, the original audio is 20 msec
The feature parameters are recorded in chronological order with 48 bits of information every 20 msec.

On the other hand, the reproduction of speech using the PARCOR synthesis method is performed purely electronically by the speech synthesis section 71. The basic configuration of this speech synthesis section 71 is shown in FIG. 5, and will be explained according to the figure. I decide to go.
In FIG. 5, 80 is a control section, 81 is a storage section,
82 is a noise generator, 83 is a pulse train generator, 84
85 is a selection section, 85 is a multiplication section, 86 is a digital filter, and 87 is a D/A conversion section. Note that the arrows in the figure indicate the flow of signals. The control unit 80 decodes signals (commands) from the microcomputer 70 and
It reads data from the ROM 72 and causes other blocks to start speech synthesis, and also transfers data in the ROM 72 and signals indicating the operating status of the speech synthesis section 71 itself to the microcomputer 70. The storage unit 81 to digital filter 86 are
It converts the audio data from the ROM 72 into a digital audio signal. D/A converter 87
After band-compressing the digital audio signal, it converts it into an analog audio signal, and drives the power amplifying section 73 and the speaker 15. (The drive level is determined by the volume part 7.
Adjustable by 4. ) is a thing. Note that although a pulse generator is further provided, a description thereof will be omitted. The operation of this block diagram will be explained by taking an example. Now, microcomputer 70
When a sound generation command signal is input to the control section 80 , the control section 80 sends a signal to the ROM 72 to call up the sound data and transfer it to the storage section 81 .
The storage unit 81 generates a signal necessary to produce a desired voice from the audio data sent from the ROM 72 to a noise generator 82, a pulse train generator 83, and a selector 8.
4, the signal is sent to the multiplication section 85 and the digital filter 86, respectively. The noise generator 82 and the pulse train generator 83 send signals to the selector 84. The selection section 84 selects the necessary one from these signals and sends it to the multiplication section 85.
send a signal to. The multiplication unit 85 multiplies the input signals and sends the signals to the digital filter 86. The digital filter 86 obtains a final digital audio signal from the input signal and sends this signal to the D/A converter. The D/A converter 87 converts the signal sent from the digital filter 86 into an analog audio signal, adjusts the overall audio signal level according to the signal from the volume section 74, and sends the signal to the power amplifier 73. send. As a result, the desired sound is emitted from the speaker 15. More specifically, when the audio to be reproduced is silent, the noise generator 82 is selected by the selection unit 84 as a signal source corresponding to the vocal cords of Iruma's audio. In addition, in the case of a voiced sound, the pulse train generator 83
is selected, and at the same time, the pitch period of the pulse train is determined based on the pitch information. The thus selected sound source signal is multiplied by the volume information by the multiplier 85 and input to the digital filter 86 . When humans vocalize, the timbre is created by characterizing the compressional waves generated by the vibration of the vocal cords by changing the shape of the vocal tract in various ways.
In the PARCOR synthesis method, a tone is formed by a digital filter 86 using PARCOR coefficients obtained during PARCOR analysis. The reproduced signal thus synthesized is converted into an analog audio signal by the D/A converter 87 and sent to the speaker 15 via the power amplifier 73. The speaker 15 produces sound based on the input audio signal. The storage unit 81 stores 48-bit information for reproducing audio for 20 msec, including volume, pitch, voiced and unvoiced identification signals, and PARCOR coefficients, and from this information, the sound source can be identified. Switching and the like are performed, and audio is played back. The information stored in the ROM 72 is intermittently sent to the storage section 81 every 20 msec by the control section 80, and the sound of the word or sentence is reproduced as a whole. Note that when the control section 80 receives an instruction to utter a voice and a start command from the microcomputer 70, it operates to play the instructed sound to the end unless a stop command is sent again, and the playback of the sound ends. Then, it automatically enters the state of waiting for commands. Therefore, the microcomputer 70 only needs to send data and commands on a one-off basis.

Next, the software of the microcomputer 70 shown in FIG. 4 will be described. FIG. 6 is a diagram showing an embodiment of a general flowchart and an interrupt processing routine. When the power of the heating device of the present invention is turned on (power on), the microcomputer 7
0 software first performs initialization. This includes clearing RAM (Random Access Memory). Next, pre-processing for heating is performed (switch input processing), such as determining whether there is a switch input to the switch sections 22, 20, and determining and setting if a switch input is present.
Furthermore, it checks whether automatic control is possible after starting heating, checks for failure of the heating mechanism, and checks for occurrence of an accidental ignition of the object to be heated. [Heat treatment (1)]. Next, automatic control and manual control are determined, and in the case of automatic control, the initial exhaust temperature value is stored, automatic control settings are determined, and whether the exhaust temperature rise value has reached the set value is determined.
Furthermore, processing is performed when the set value is reached (automatic control processing). In the case of manual control, the number of heating stages is determined, whether the set time has been reached, and processing is performed at that point (manual control processing). Furthermore, the processing associated with the opening and closing of the door during heating is performed [heating processing (2)], and the processing of the 12-hour clock and heating timer is performed (clock & timer processing). Finally, the process when the repeat switch 41 is operated is performed (repeat process), and the process returns to the initial setting end point. On the other hand, two interrupt processes are always performed. The first one is an interrupt caused by a timer mechanism inside the microcomputer 70, and when this interrupt occurs, the display on the fluorescent display tube 21 and the switch section 2
2 and 20 and processing associated therewith are performed. The second is an interrupt caused by the clock signal generator 77,

Next, regarding the general flowchart of FIG. 6, the general flowchart of each block will be shown. First, with reference to FIG. 7, common depictions of these blocks will be defined. The hatched processing display shown at the top of FIG. 7 is the same as the discrimination and processing display shown below. That is, the above predetermined voice is uttered by the lower volume with switch 42.

Reference numeral 108 is a heating restart notification when the door 4 is opened and then closed again during heating, and utters "Heating will be restarted." Reference numeral 109 is a temporary stop notification when the door 4 is opened during heating, and is uttered "Heating will be temporarily stopped." Reference numeral 110 is a notification of a predetermined time in the clock function, and is uttered such as "It's 12 o'clock."

In FIG. 15, 112 is a heating mechanism, 113
114 is a sound generation mechanism; 114 is a control mechanism; 115 is an operating section; 7 is a temperature sensor that detects the temperature of the fluid (exhaust gas) discharged from the heating mechanism 112; 123 is an accident detection means for detecting a fire accident in the heating mechanism 112 based on the output of the temperature sensor 7; 120 is a selection means included in the control mechanism 114; 121 is included in the control mechanism 114. It is a voice control means. Note that thin arrows in the figure indicate the flow of signals, and thick arrows indicate the flow of fluid discharged from the heating mechanism 112.

Assume that the user inputs a predetermined switch on the operation unit 115 regarding automatic heating (automatic heating of the object to be heated). Operation unit 115
supplies the input signal to the control mechanism 114.
This allows the control mechanism 114 to control the heating mechanism 112.
to drive. The heating mechanism 112 heats an object to be heated (not shown) and discharges fluid accordingly. In the embodiment shown in FIG.
If the heating mechanism 112 operates normally, the temperature will rise as the heating time elapses. Automatic heating can be performed by utilizing this proportional relationship between the temperature rise of the fluid and the temperature rise of the object to be heated. On the other hand, if the temperature does not rise or if the temperature drops, it means that heating is not occurring, and it can be determined that a failure has occurred. Furthermore, since the temperature of this fluid rises rapidly and to a very high temperature when an object to be heated ignites, it is possible to determine whether a fire accident has occurred. The temperature sensor 7 detects the temperature of this fluid and sends a detection signal to the control mechanism 114, failure detection means 122, and accident detection means 123.

The failure detection means 122 receives the detection signal from the temperature sensor 7, determines the increase value of the fluid temperature at the initial stage of heating, and if it has not increased, sends a signal to the control mechanism 114 (particularly to the selection means 120) indicating that a failure has occurred. . When the control mechanism 114 receives a signal indicating the occurrence of a failure from the failure detection means 122, it stops driving the heating mechanism 112. Further, the selection means 120 in the control mechanism 114 selects the voice data "A failure has occurred in the heating mechanism" from among the voice data stored in advance through the process 99 in FIG. It is sent to the voice control means 121. The voice control means 121, which is a part of the control mechanism 114, supplies a signal related to this voice data to the voice generation mechanism 113, and as a result, the voice generation mechanism 113 outputs a voice notification that "a failure has occurred in the heating mechanism." This is done by following the instructions.

Further, the accident generating means 123 receives a detection signal from the temperature sensor 7, and when the temperature indicated by this detection signal suddenly rises to a very high temperature, the accident generating means 123 determines that an ignition (fire) accident has occurred and sends the control mechanism 114 (especially selected means 120). Control mechanism 1
14 stops driving the heating mechanism 112 when a signal indicating the occurrence of an accident is supplied from the accident detection means 123. Further, the selection means 120 in the control mechanism 114 selects the voice data "Fire accident has occurred" from among the voice data stored in advance through the process 100 in FIG. It is sent to the means 121. The voice control means 121 supplies a signal related to this voice data to the voice generation mechanism 113, and as a result, the voice generation mechanism 113 issues a voice notification to the effect that "a fire accident has occurred."

If the heating progresses smoothly without failures or accidents, the temperature of the fluid increases as the temperature of the object to be heated increases, and eventually the temperature increase value of the fluid reaches a preset value. That is, the level of the output signal of the temperature sensor 7 input to the control mechanism 114 reaches a predetermined level. At this point, the control mechanism 114
is the heating mechanism 1 based on the signal from the temperature sensor 7.
12 is stopped. Furthermore, the control mechanism 11
The selection means 120 in the voice control means 120 selects voice data such as "I boiled it." from among the voice data stored in advance, and sends this voice data to the voice control means 121. The voice control means 121 supplies a signal related to this voice data to the voice generation mechanism 113, and as a result, the voice generation mechanism 113 issues a voice notification indicating that the heating is complete, ``I boiled it.''

In addition, the user can adjust the voice production conditions by changing the volume, changing the speech rate, repeating the voice, etc. for a specific voice production, and providing a voice volume adjustment function, a voice disabling function, and a voice re-voice function. It is now possible to set
Because it uses the PARCOR system, the sound quality is good, and because the main components of the sound generation mechanism are ICs, the cost is low.

In the above embodiments, a high frequency oscillation tube was used as the heating source, but an electric heater, gas burner, boiler, etc. may also be used, and the present invention is also effective even when these heating sources are used in combination.

Furthermore, in the above embodiments, instructions for the progress of the heat treatment are given in the case of manual control, but the present invention is also effective even if the instructions are given in the case of automatic control. In addition, although the output and time are specifically uttered, the ambient temperature inside the heating chamber may also be uttered audibly when the heating source is an electric heater, etc. Also, in a device with a variety of heating sources, it is possible to utter audible information about the temperature of the atmosphere in the heating chamber. The present invention is effective even if the switching between automatic control and manual control is notified by voice.

Further, the present invention is also effective even when the heating time or the atmospheric temperature within the heating chamber is notified by sound.

Even if you do this, the effect of the present invention will not change.

In addition, in the above embodiment, the end of heating was given one minute's notice, but it may be given before or after that time.Also, although the remaining heating time was given notice, the notice was given based on the atmospheric temperature in the heating chamber, etc. However, the present invention is still effective.

Further, in the above embodiment, the notification of the end of heating was made different depending on automatic control and manual control, but in the case of a device having various heating sources, it may be made different depending on the heating source used. Furthermore, the present invention is effective even if it is varied depending on other conditions.

In addition, in the above embodiment, a door switch and a temperature sensor are used as safety devices, and an alarm is issued by voice when the safety device is activated. However, other safety devices may be used, and the operation of the safety device may be The present invention is effective even if the forecast is made at the expected time.

Further, in the above embodiment, the alarm is given by voice when an accident of ignition of the object to be heated occurs, but the alarm may be given also in case of other accidents. In addition, we have discussed cases in which the volume is increased, the speaking speed is increased, and the voice is repeated in an accident warning;

Further, in the above embodiment, a method of detecting the exhaust temperature is used as an automatic control method, but the present invention is also effective using an exhaust humidity method, a temperature sensor insertion method, or an infrared method. The present invention is also effective in cases where the state of the heated object, such as thawing, boiling, burntness, fermentation, etc., is detected and automatically controlled by detecting the reflected light from the heated object using an optical sensor. In particular, in the temperature sensor insertion method,
This is effective in notifying an erroneous operation when a temperature probe is attached or detached incorrectly when automatic control or manual control is selected.

Furthermore, the present invention is also effective even if the operation section (input/output device) in the above embodiment is provided with a switch having a function of changing the voice production speed.

In addition, in the above embodiment, the operation unit is equipped with a magnetic card reader, a paper card optical reader, a barcode reader, etc., and inputs a heating pattern and audio output (instructs the audio data already stored). The present invention is also effective in cases where a magnetic tape reader is provided, audio data analyzed in advance is input, and the input audio is uttered.

Furthermore, in the above embodiment, specific settings, etc. are displayed on the fluorescent display tube and notified by voice, but it is also possible to display all settings related to the sound to be emitted, and also to be notified by voice. The present invention has an effect even if the configuration is such that it is not displayed.

In addition, the heating device of the present invention is provided with a calculation function that is valid except during heating instead of the clock function, and a calculation function switch is provided in the operation section (input/output device), so that it can be used as in the above embodiment. The present invention is effective even when a voice is uttered in various cases. In particular, the same effect can be achieved even if only the calculation results are announced by voice.

Further, in the above embodiment, the case where the object to be heated is stored in the heating chamber has been described, but the present invention is also effective in the case where the object to be heated is heated without providing a heating chamber.

Furthermore, in the above embodiments, the case of heating a predetermined object to be heated has been described, but the present invention is also effective when heating a room. In particular, in the case of a heating device that heats a room, an alarm is set when a safety device is activated to prevent a fire from going out due to a ignition just before running out of fuel, or to prevent poisoning, explosion, or fire due to gas leakage. It is useful to inform the public of the reasons for this.

Further, in the above embodiment, the control mechanism is provided with a voice analysis and analysis result judgment function, and
The present invention is also effective when the function of the operation section is a voice capture function and input is made to the control mechanism by voice.

This (warning of erroneous operation, instructions on operating procedures) is particularly effective.
