This cover 32 is bonded with adhesive in parts other than the display part 16, and the display part 16 and the operation part 17 are attached to the surface of the cover 32 as shown in FIG.
Required printing corresponding to the above is applied. By providing such a cover 32, it is possible to completely prevent water from entering the precise key group for this type of cooking device that requires the use of water, and electrically connect the outside and the inside. It is completely insulated and can prevent short circuit accidents. Next, the control circuit for the motor 5 will be explained with reference to FIG.

First, the motor 5 is connected to a commercial AC power source 33 together with the safety switch 8, bimetal switch 34, and triac 35. In addition, these safety switches 8,
Motor 5, bimetal switch 34 ~ triax 35
A diode 36, resistors 37 and 38, and a diode 39 are connected in parallel to the . This zener diode 3
A smoothing capacitor 40 is connected in parallel to Zener diode 39 and resistor 38, and a smoothing capacitor 41 is also connected in parallel to Zener diode 39 and resistor 38.
9, a power supply voltage Voo for the control circuit, that is, for the microcomputer CPU 42 is created. Here, the motor 5 is provided with a brake coil 43, and one end of this brake coil 43 is connected to the It is connected to the OFF terminal A of the safety switch flea, and its terminal end is connected between the armature 44 and the field coil 45. The terminal end of this field coil 45 is connected to the triac 35 via another field coil 46. The remaining brushes of the armature 44 are connected to the common terminal C of the safety switch 8.The ON terminal B of the safety switch 8 is connected to the AC power supply 33. A resistor 47 and diodes 48 and 49 are connected to the common terminal C, and a power supply frequency signal Vs, is connected to the common terminal C.

has been taken out. These power supply frequency signals Vs, G are transmitted to the 4-bit one-chip French CPU via a diode 50.
It is input to the K8 terminal of 42. That is, Figure 8a
From the voltage waveform of the AC power supply 33 shown in FIG. 3, a diode 48 extracts a negative power supply voltage with respect to the voltage Vss as shown in FIG. The positive side power supply voltage is extracted from the positive side power supply voltage, and both are combined to form a power supply frequency signal VsIG as shown in d of the same figure. And the diode 60 has a voltage Vss
The voltage drop of the diode 48 on the more positive side is canceled and input to the terminal of the ACPU 42.
Adjust so that it does not exceed the power supply voltage. Also, ACPU
42, first, a built-in oscillator is oscillated by a capacitor 51 between the Vss terminal and the OSC2 terminal, and a semi-fixed resistor 52 between the OSC and Voo terminals, and a clock signal is given to the ACPU 42.

The INIT terminal is at H level with respect to the power supply voltage Voo to clear the CPU 42, and is at L level to execute the program. Therefore, when the power is turned on,
An electrolytic capacitor 53 is connected between the WIT terminal and the Vss terminal so that the level is maintained and the program counter is preset during this time to make the output L level, and the output becomes L level later than the power supply voltage VDo. This electrolytic capacitor 53 provides a power supply voltage Vo. This prevents unexpected programs from running during startup.
The collector of a PNP type transistor 54 is connected to the negative side of the electrolytic capacitor 53, and its emitter is
It is connected to the ss terminal, and the collector of a PNP type transistor 55 is connected to the base. The collector of this transistor 55 is connected to the VoD terminal via a resistor 56, and the base side has the voltage between the resistors 37 and 38 (VDD
Resistors 57 and 58 are connected to divide the voltage ('-Vss). Then, as an input relation of the CPU 42, K
Signals from keys 22, 23, and 24 are input to the , terminals, and signals from the key 25, clear key 26, and start key are input to the K2 terminal.
A signal from the stop key 27 is input, and a signal from a changeover switch 59 for 50 days, 2, and 60 Hz is also input to the K4 terminal. This changeover switch 59 is 50Hz
When this is closed and voltage Vss is input, 50H
It executes a program for Z. Also, French CP
Regarding the output relationship of U42, the signals from the 0o to 06 terminals are connected to the transistors 60, 61, 62, 63, 64, 65, 6.
It has been added to the Emitsuta side of 6. As a result, the transistors 60 to 66 are driven to appropriately flow current to the seven segments of the LED 18, and the transistors 67, 68, 69, 7 are driven by the output from the Ro to R8 terminals of the French CPU 42.
By drawing each digit of current through 0 one after another, LE
This is to light up D18 for each digit. The signal of the Ro terminal is also given to the keys 22 and 25, the signal of the R terminal is given to the key 23 and the start/stop key 27, and the signal of the R2 terminal is given to the key 24 and the clear key 26, respectively. . Furthermore, the R5 terminal generates an output for the piezoelectric buzzer 71, and when a key is pressed or the timer ends, this piezoelectric buzzer 71 is output via a transistor 72.
1 for a short period of time. The signal from the R7 terminal is input as a gate signal to the gate of the triac 35 via the transistor 73. In this circuit, the power supply voltage VoD is generated without using a transformer and is stepped down by resistors 37 to 38, so that it can be made smaller.

In this case, by dividing the resistors 37 and 38 into two and connecting the capacitors 40 and 41, the power supply voltage VoD
The ripple can be reduced more than when the capacitor 40 is inserted only in this. Since the voltage (V..'-Vss) at the voltage dividing point of the resistors 37 and 38 is used as a signal for the discharging circuit formed by the transistors 54 and 55, etc., when the power is turned off, a reliable and quick reset is possible, and instantaneous reset is possible. Malfunction of the ACPU 42 can be reliably prevented even if the ACPU 42 is turned on again. As a result, even in the event of an instantaneous grounding accident such as during a power outage, the motor 5, which had been rotating at a low speed, will not suddenly rotate at a high speed. That is, according to this power supply circuit, the voltage Voo' is normally maintained at a more negative voltage than the power supply voltage Voo with respect to the voltage Vss, and the resistors 57 and 58 make the divided voltage slightly lower than the base-emitter saturation voltage of the transistor 55. resist,
By setting the voltage to this transistor 55,
is ○N, the transistor 54 is OFF and the electrolytic capacitor 53 is electrically isolated from this transistor 54, but
The AC power supply 33 has a power supply voltage V. . Since the voltage VDo' starts to decrease before the voltage decreases, the base voltage of the transistor 55 approaches the voltage Vss, the transistor 55 turns OFF, the transistor 54 turns OFF, and so on.
In an instant, the electric charge of the electrolytic capacitor 53 is discharged, and the AC
The INIT terminal of the PU 42 is pulled up to the voltage Vss to perform a clearing operation. Therefore, the power turns off instantly.
If you repeat the N/OFF cycle, for example, if you immediately restart cooking after finishing cooking and unplugging the power outlet, the ACPU 42 will be cleared in an instant, so the ACPU 42 will not malfunction. The program will be executed without any problem. Also, regarding the safety switch 8, ``If the lid 4 is locked in the normal position, the motor 5 can be energized, and even if the lid 4 is energized, if the lid 4 is removed or moved from the normal position, the safety switch will be activated. OFF
The brake coil turtle 3 and the armature 44 are connected in series without intervening the field coils 45 and 46, forming a closed circuit, a kind of short-circuited generator, and cutting under a large braking force. Immediately stop the rotation of the blade 16.

And, from a circuit perspective, safety switch 8 is connected to #CPU4.
When the safety switch 8 is turned FF, the power to the motor 5 is cut off, the gate signal to the gate of the triax 35 is stopped, and the CPU 4
The timer time and operating speed stored in 2 remain as they are. In other words, even if the safety switch 8 is in the OFF state with the lid 4 removed, the cooking time and speed can be set, and the operation procedure is not limited and is easy to use. If you are in the middle of cooking, even if you remove the lid 4 and add food to it, just lock the lid again and press the start/stop key 27.
It is possible to restart cooking with the previous setting information, and the total cooking time can be known without having to calculate it, allowing you to cook data without relying on intuition.
The result is always the best cooked food. Furthermore, the ON/OFF signal of the safety switch S is taken out from the common terminal C on the current-carrying side of the motor 5, and a power supply frequency signal Vs, which is used for a timer. Since this is also used as the ON/OFF signal for the safety switch 8, the power supply frequency signals Vs and G, which are susceptible to adverse effects such as surge noise and high frequency noise based on the AC power supply 33, are turned off when the safety switch 8 is turned OFF. This eliminates malfunctions, prevents the cook from being injured, and prevents the cutting blade 15 from rotating against the cook's will and damaging the food, making it safe. Next, the program of this embodiment will be explained according to the flowcharts of FIGS. 9 to 11.

First, when you turn on the power plug, the RA in the ACPU42
M is automatically cleared. The time setting is set to "C" which means continuous operation, and the operating speed is set to "0" from among the speeds of "1" to "6" and "0" which means no lotus rotation. Ru. Next, the K terminal input is 50H
Check whether it is Z or 60HZ, and if it is set to 50 days 2, set the 50 days 2 flag. In this way, the initialization operation is performed. Subsequently, it is determined whether the lid 4 is locked, that is, whether the safety switch 8 is in the ○N position, and if the safety switch 8 is in the ○N position, the process moves to the 45hs counter.

And the count content of this 45hS counter is 45h
If it is not 48hs or more, it is determined whether the power supply frequency signal Vs,c for the K3 terminal is at the H level or the L level with respect to the power supply voltage VDo. Here, whether it is H level or L level,
It is determined whether the H level and L level are the first ones. In other words, it detects the zero crossing of the power supply waveform as a switching from H level to L level and L level to H level for the K8 terminal.In this case, if the state with no level change continues, it will be detected whether it is the first H level or L level. The determination result is NO, and the half cycle of 50Hz is 1 hs, 60H
The count-up continues for 45ms beyond the Z half cycle of 8.3hs, and when the count reaches 48hs or more, the start flag is cleared and the lid brewing is displayed while the time and speed are memorized. On the other hand, if there is a level change and the determination of whether it is H level or L level for the first time becomes YES, after clearing 45ms, it is determined whether the start flag is 1, and if the start flag is not set, LED 1 is displayed.
8. Move to the display program. That is, a dynamic display operation is performed in which output is output from terminals ○o to 06 and outputs are output from terminals Ro to R8 depending on the digit. in this case,
When operating this dynamic display, input the input signal to the K terminal or the K2 terminal corresponding to the output of the Ro to R2 terminals to R.
If there is a signal, the process moves to the key processing routine shown in FIG. 10, which will be described later. And the display by LED18 is “
Along with the operation of this dynamic display, the 4-digit lighting operation is performed within a half cycle of the AC power supply 33 by carrying up the lighting digit and determining whether the 4-digit is completed.By the way, when the safety switch 8 is OFF, is 9.2hs
It enters the counter and is displayed in 4 digits within 9.2hs, which is the intermediate value between the 50Hz half cycle hs and the 60Hz half cycle 8.3hs. Then, when the 4-digit display is completed, the input prohibition counter counts each time the routine is run.
If the interval between key inputs is 0.1 seconds or more, a flag is raised to remove the input prohibition, and if the piezoelectric buzzer 71 that sounds due to the key input does not sound, it will pass through as is.
If the piezoelectric buzzer 71 is still ringing, the ringing of the piezoelectric buzzer 71 is cleared with 1 wind s. Next, it is determined whether the start flag is 1, and if it is not standing, it is determined whether it is the end buzzer. If the end buzzer is not sounding, it is determined whether the initial safety switch 8 is ON. Return to discrimination.
These routines form a constant processing routine loop. Then the key processing routine
This will be explained using Figure 0.

In the above-mentioned constant processing routine, after storing in the RAM the input signals to the K terminal or the K2 terminal corresponding to the output from Ro to R2 during dynamic display operation, if there is a signal, the process moves to this key processing routine. , First, the power supply frequency signal Vs, which is always input to the K8 terminal when the lid 4 is locked. Omit the lid.
After setting the flag to 1, return to carrying the lit digit. When there is an input to the K terminal or the K2 terminal, it is determined whether the input prohibition counter has been canceled or not based on whether the key interval is 0.1 seconds or more, and if the input prohibition counter is disabled, the input prohibition counter is cleared. On the other hand, if the input prohibition counter has been released, it is determined whether the number of key press operations is 3 or more hs. This determination is effective in preventing chattering of key inputs, uncertain key inputs, or noise entering the AC power supply 33, as well as the function of the input prohibition counter. Thereafter, if the key operation is 3 seconds or more, a signal is output from the R5 terminal and the piezoelectric buzzer 71 is driven by the transistor 72 to make it sound. Next, it is determined whether the input is to the K2 terminal or the K, terminal.
Here, if the input is to the K2 terminal, it is determined whether it is the key 25 for auto pulse. If this key is 25,
After the pulse signal is stored in the RAM, the process returns to the carry-up of the lit digit in the regular processing routine. If the signal is not from the key 25, it is determined whether it is the start/stop key 27, and if it is the start/stop key 27, it is further determined whether it is a start signal or a stop signal. Determine. If it is for a stop, clear the start flag, memorize the time, speed, auto pulse signal, etc. as they are, and return to carrying the lit digit. If it is a start signal, continuous operation "C"
Or, after confirming that the timer is set, set the foot flag to 1. Note that the determination as to whether the key is for start or stop is performed by alternately distributing the signals of the start/stop key 27. Furthermore, if it is not the start/stop key 27, it is determined whether it is the clear key 26, and if it is the clear key 26, it returns to the start of the program, clears the RAM, sets the continuous operation to "C", and sets the speed to "0". Set to . On the other hand, if there is an input to the K terminal, it is determined whether it is the key 22 "x10" for time setting, and if it is this key 22, the display section 16
Raise the first digit in .

In other words, if the second digit is x, the key 22
Depending on the operation, it will become "Melon", "Lx", "Koichi", "Scale", and after "Ball" there will be only "C" which is a continuous operation display, and the second digit (g x 1" digit) will be stored in RAM. The second digit is memorized, and when the next key 22 is input, this second digit is recalled and becomes ``ship''. Also, if the key 23 is "x1" for time setting,
At the second digit on the display section 16, move up the "x1" digit in sequence.
Further, if the speed setting key 24 is operated, the line is raised in the order of "0", "1" to "6", "0", etc., and the speed is set. In this case, the firing angle constant corresponding to the set speed step is stored in the RAM. In this way, a loop of key handling routines is formed. Further, the ignition processing routine will be explained with reference to FIG. 9 together with the timer processing routine shown in FIG. 11.

First, when the foot flag is set, the routine proceeds to the determination of the foot flag in the regular processing routine to determine whether it is pulse setting. Then, if the pulse setting is not set, it is determined whether the speed is "6", and if the speed is "6", it is 0.
．． Apply a 36 mS trigger pulse to the triax 35,
The timer processing routine shown in FIG. 11 is called. This timer processing routine uses the commercial power supply frequency of 50Hz or 60Hz; if the frequency is 50Hz, 5 solid pulses are counted as 1 second, and if the frequency is 60Hz, 6 solid pulses are counted as 1 second. Second. First, the levels of the power supply frequency signals Vs and G are selected, and timer processing is not performed at L level, but timer processing is performed only at H level. In the case of H level, it is determined whether the 50HZ flag is set, and if it is set, it is 50HZ and the 50 counter is entered, and if it is not set, it is 60HZ and the 60 counter is entered. Then, it is counted by a 4 second repeat counter used for auto pulse or end buzzer.
The processes up to this point are performed in the same way even if continuous operation "C" is set, but if the timer is set, it is determined whether the end buzzer is being sounded. If the end buzzer is being sounded, return to the original routine (Z), otherwise subtract 1 second from the current time. After the subtraction, it is determined whether the set time has elapsed and the number of inkstones has reached zero. If there is still time left, return to the original routine, and if there is 00 seconds left, set the end buzzer, clear the foot flag, and return to the original routine. Also, if the setting is other than "Speed r6", "
After determining whether the foot flag is set and determining whether the speed is set to "6" or pulse, the firing angle corresponding to the set speed "1" to "5" is read from the RAM.

Here, in 50 days 2 or 60 days 2, even if the ignition time is the same from the time of Xerox, the ignition angle is different.
Determine whether the 50HZ flag is on and set 5 for each.
The 50 day 2 firing angular force counter and the 60 Hz firing angular force counter are selected to obtain the same power consumption according to 0HZ and 60 day 2, and the firing angle pulses that reach the set speed are calculated by the triac 36 gamer. give to Then, the timer is called and the process moves to the timer processing routine. At this point, if the timer has finished and the end buzzer is sounding,
It is determined whether the end buzzer is being sounded, and further it is determined whether the end buzzer is within 2 seconds, thereby reducing the contents of the 4 second repeat counter in the timer processing routine.
If it is 2 seconds or more, the end buzzer is stopped and the process returns to the initial determination of whether the safety switch 8 is ON in the regular processing routine.

If it is within 2 seconds, the process moves to a timer processing routine to advance the 4-second repetition counter.

In the case of pulse setting, the display on the display unit 16 will be "x, x, "P", but the operation will be repeated at speed "6" with 2 seconds of operation and 2 seconds of rest.

Therefore, if the pulse setting is set, it is first determined whether the pulse counter, that is, the 4-second repetition counter, indicates the operating time or the rest time. Driving time, speed 6
As in the case of , an ignition pulse is given, and if it is a pause time, a timer processing routine is called to advance the timer. These constant processing routines, key processing routines, ignition processing routines, and timer processing routines perform cooking according to the settings.

Next, specific operations and their displays will be explained. First, when the power plug is turned on as a preparation step, the display is automatically cleared and "continuous operation "C" and speed "0" are displayed on the display section 16 as shown in FIG. 12a. At this stage, the lid display may be turned on or off depending on whether the safety switch 8 is turned on or off. Next, the time is set by operating the keys 22 and 23. This setting range is 00-9
It is parent sand, and if it is not operated, it will be continuous operation "C". For example, if you want to set 39 seconds after displaying "00" seconds, press the "x10" key 22 three times and the "x1" key 23 nine times, and the display will appear as shown in Figure 12. It will be displayed. If it is desired to change the time set in this way, it can be done by continuing to operate the keys 22 and 23 or by clearing the time using the clear key 261 and resetting. Then, the speed is set by operating the key 24. In other words, "0" to "6" depending on the number of times you press it.
Speed setting is performed in stages. For example, 5 times key 2
When 4 is pressed, the speed "5" is set and displayed as shown in FIG. 12c. This speed change is also performed in the same way as the time change. After setting the time and speed as described above, operation begins by operating the start/stop key 27.

In this case, it is checked whether the third digit grid display of the L display section 16 is lit. That is, if the lid 4 is locked in the normal position, the safety switch 8 is turned on and the display section 16 displays the lid as shown in FIG. 12d. On the other hand, if the lid 4 is removed or not in the normal lock position, the lid display will not be performed and the start/stop key 2 will not be displayed.
7 does not work. Since the lid display is performed in this way, and the time and speed are also displayed on the same display section 16, for example, if the power outlet is disconnected, the entire display section 16 will be dimmed and no display will be made. On the other hand, if the lid 8 is removed, only the lid display will be dimmed and not displayed, allowing the two to be distinguished even if they do not operate in the same way. After all, it is possible to know all the setting states and the state of the cooking device just by looking at the display contents of the display section 16, and the cooking procedure can be improved and the cooking time can be shortened. After confirming the lid display in this way, when the start/stop key 27 is pressed, the moder 5 is started and cooking begins. At this time, the time displayed on the display unit 16 is displayed by subtracting one second at a time as time passes. Then, when the remaining time reaches 00 seconds, the piezoelectric buzzer 71 stops sounding. By the way, if you have set the time like this or set it to continuous operation "C" and want to stop the motor 5 during operation, just press the start/stop key 27 again. . With this operation, the start/stop key 27 acts as a stop key, the motor 5 stops, and the display section 16 shows the remaining time (or r
C"), the speed is displayed fixedly. If you wish to restart the operation, you only need to press the start/stop key 27 once more. After all, even if the continuous operation is set to "C" or the time is set, if you want to stop the operation depending on the cooking status etc. during operation, operate the start/stop key 27 that started the operation. You can stop the cooking process without any confusion, and you can get food in the optimal cooking state. Further, if intermittent operation is desired, pulse setting may be performed using the key 25 instead of setting the speed using the key 24.

That is, when the key 25 is pressed, the display section 16 displays "P" instead of the speed, as shown in FIG. 12e. At this time, even if the time is continuous operation "C",
The time setting may be from "oo" to "99" (this time is the total time of operation and rest). Therefore, when the start/stop key 27 is pressed, intermittent operation is performed, but the speed is in "6" stages, and the operation is repeated for 2 seconds and then paused for 2 seconds. Incidentally, by setting a predetermined speed using the key 25 and repeating starting and stopping by operating the start/stop key 27, intermittent operation can be performed even at speeds other than speed "6". In this respect as well, the specifications can be expanded by providing a start/stop key 27 that also serves as a start/stop function. Furthermore, if you want to operate only the timer regardless of the motor 5, the 12th
Set the required time as shown in Figure f (for example, 6 inkstones)
While doing so, set the speed to "0" and press the start/stop key 27.

As a result, as time passes, the display will be subtracted by 1 second and will be displayed as 0.
When the bait is ready, the piezoelectric buzzer 71 sounds to notify that the time is up. Such a function can be used as a reference for preparation time, etc. As described above, the present invention provides a start/stop function that has various keys on the operation unit as well as a start/stop function.
Since a stop key is provided, it is possible to stop the cooking machine by operating the start/stop key as necessary during the operating state, regardless of the time setting, etc. Therefore, depending on the cooking state, the cooking state can be started and stopped by operating the same key without confusion. Furthermore, intermittent operation can be performed simply by operating the start/stop key.
