Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance such as a food processor.

Conventionally, in this type of cooking appliance, there are various types of control circuits that control the operating time and operating speed.

In order to ensure safety, some devices are equipped with a safety switch that detects whether the lozenge is attached to the container in a normal locking position, thereby enabling or disabling power to the motor. However, when this safety switch is in the OFF state, it is impossible to energize the motor, and the power to the control circuit is also OFF, which is the same as when the power outlet is unplugged. I can't tell if the cooker is disconnected or the safety switch is turned OFF. Therefore, the subsequent steps are confusing.

A switch piece 9 for opening and closing the safety switch 8 is formed on a part of the circumferential side of the lid 4. Here, when the container 3 and the lid 4 are in a normal lock set state, the switch piece 9 is located at the position shown by the solid line in FIG. The safety switch 8 is positioned by a mechanism, and when it deviates from the normal locking position, the safety switch 8 is opened as shown by the dashed line in FIG. Further, the motor shaft 1 of the motor 5

It is. Further, as shown in FIG. 5, the PC board 20 having the LED 18 is fixed to a decorative plate 19 provided to fit the front entrance of the main body case 1. A transparent display plate 21 is fixed to the decorative plate 19 so that the LED 18 can be seen through the display section 16 in its lighting state. On the other hand, the operation unit 17 has a plurality of keys, from the left, a key 22 for setting the operating time in units of 1 sand ("x10"), and a key 23 for setting the operating time in units of 1 second ("x1"). , a key 24 for setting a plurality of predetermined operating speeds (in this embodiment, stop "0" and stages "1" to "6"), and an auto pulse key for intermittent operation every 2 seconds. 25, a clear key 26, and a start/stop key 27 which also serves as a start/stop function. Looking at its specific structure, for example, the start/stop key 27, "As shown in FIG.
ABS sheets 29 and 30 having conductive parts facing each other are provided on top of the sheet 8, with a vertical edge spacer 31 interposed between them to maintain the distance between the conductive parts. The same applies to other keys 22 and the like. And the plaque 19
A flexible cover 32 made of polyester sheet or the like is provided over the entire front surface. This cover 32 is bonded with an adhesive except for the display section 16, and the surface thereof has required printing corresponding to the display section 16 and the operation section 17, as shown in FIG. By providing such a cover 32, it is possible to completely prevent water from entering the precise key group of this type of cooker that uses water, and it is possible to completely prevent water from entering the precision key group, and also to electrically connect the outside and the inside. It is completely insulated and prevents short fall 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 3
A diode 36, resistors 37 and 38, and a diode 39 are connected in parallel to the transistor 5. A smoothing capacitor 40 is connected in parallel to the Zener diode 39, and a smoothing capacitor 41 is connected in parallel to the Zener diode 39 and the resistor 38.
The power supply voltage Voo for the control circuit, ie, the microcomputer CPU 42, is created by the voltage of 9. Here, the motor 5 is provided with a brake coil 43, the negative end of the brake coil 43 is connected to the OFF terminal A of the safety switch 8, and the other end is connected between the armature 44 and the field coil 45. It is connected. The other end of this field coil 45 is connected to the triac 35 via another field coil 46. Further, the remaining brushes of the armature 44 are connected to the common terminal C of the safety switch 8. An ON terminal B of the safety switch 8 is connected to an AC power source 33. On the other hand, a resistor 47 and diodes 48, 49 are connected to a common terminal C of the safety switch 8, and power frequency signals Vs, G are taken out.

The power supply frequency signals Vs and G are inputted via a diode 50 to the K8 terminal of the 4-bit one-chip rCPU 42. That is, the AC power supply 33 shown in FIG. 8a
From the voltage waveform of , the diode 48 takes out the negative side power supply voltage with respect to the voltage Vss as shown in the figure b, and the diode 49 takes out the positive side power supply voltage with respect to the power supply voltage Voo as shown in the figure c This results in a power supply frequency signal VsIG as shown in d of the same figure. The diode 50 cancels the voltage drop of the diode 48, which is on the positive side of the voltage Vss, and
input it to the K8 terminal of the ACPU 42 and adjust it so that it does not exceed the power supply voltage of the ACPU 42. Also, when looking at the ACPU 42, first of all, the capacitor 51 between the Vss terminal and the OSC2 terminal
A built-in oscillator is caused to oscillate by the OSC and a semi-fixed resistor 52 between the terminal and the VoD terminal, and a clock signal is given to the French CPU 42.

The INIT terminal is used to clear the CPU 42 at H level with respect to the power supply voltage Voo, and to execute a program when it is at L level. Therefore, when the power is turned on,
While holding the level, the program counter is preset and the output is set to L level, and the power supply voltage is V. An electrolytic capacitor 53 is connected between the state IT terminal and the Vss terminal so that the level becomes L level later than D. This electrolytic capacitor 53 prevents an unexpected program from being executed while the power supply voltage Voo is rising.
The collector of a PNP type transistor 54 is connected to the negative side of the electrolytic capacitor 53, and its emitter is connected to V
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 VDD terminal via a resistor 56, and the base side is connected to the voltage (V.D) between the resistors 37 and 38.
Resistors 57 and 58 are connected to divide the voltage ('-Vss). Then, as an input relation of the ACPU 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 50Hz/60Hz changeover switch 59 is also input to the K4 terminal. This cut-off switch 69 is 50 days 2
When this is closed and voltage Vss is input, 50H
It executes the Z program. Also, rCPU
42, the signals from the 0o to 06 terminals are transmitted to the transistors 60, 61, 62, 63, 64, 65, 66.
It has been added to the Emitsuta side. As a result, the transistors 60 to 66 are driven to appropriately flow current to the 7 segments of the LED 18, and the transistors 67, 68, 69, 70 are driven by the output from the Ro to R3 terminals of the French CPU 42.
By drawing the current of each digit one after another through the LED
18 is turned on 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 the key is pressed or the timer ends, the piezoelectric buzzer 71 outputs an output via the transistor 72.
It sounds for a short time. The signal from the R7 terminal is input as a gate signal to the gate of the triac 35 via the transistor 73. Therefore, in this circuit, the power supply voltage V.

. The method of making the resistor 37,3 without using a transformer.
Since the voltage is stepped down by 8, 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 ripple of the power supply voltage Voo can be reduced more than when the capacitor 40 is connected only to this. . And the transistor 54,
Since the voltage (V..'-Vss) at the voltage dividing point of resistors 37 and 38 is used as the signal for the discharge circuit such as 55,
When the power is turned off, reliable and quick IJ setting is possible.
Malfunctions of the rCPU 42 can be reliably prevented even if the power is turned on again instantaneously. 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' normally maintains a voltage that is more negative than the power supply voltage VoD with respect to the voltage Vss, and the resistor 57
, 58 to a voltage slightly lower than the base-emitter saturation voltage of the transistor 55, this transistor 55 becomes ○N, and when the transistor 54 is OFF, the electrolytic capacitor 53 is electrically connected to this transistor 54. However, the AC power supply 33 is at the power supply voltage V. . Since the voltage Voo' starts decreasing before the voltage decreases, the base voltage of the transistor 55 approaches the voltage Vss, and this transistor 55 becomes ○.
The FF transistor 54 turns ON, instantly discharging the electric charge of the electrolytic capacitor 53, and reducing the INI of the French CPU 42.
The T terminal is pulled up to voltage Vss to perform a clearing operation. Therefore, even if the power is repeatedly turned on and off instantaneously, for example, when cooking is finished, unplugged from the power outlet, and then resumed immediately, the ACPU 42 is cleared in an instant. , ACP
U42 will execute the program without malfunctioning. 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 removed or the safety switch 8 is shifted from the normal position, the OFF terminal When switched to the A side, the brake coil 43 and the armature 44 are connected in series without the field coils 45 and 46 in an open circuit, that is, a kind of short-circuited generator, and the cutting blade 15 is switched to the A side under a large braking force. stop rotating immediately.

Also, from a circuit perspective, safety switch 8 is connected to ACPU4.
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 try hook 35 is stopped, and the ACPU 42
The timer time and driving speed stored at that time will remain the same. 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 additional food, you can simply lock the lid 4 again and press the start/stop key 27 to continue cooking with the previous setting information. The total cooking time can be known without calculation, and cooking can be done using data without relying on intuition. The result is always the best cooked food. Further, the ON/OFF signal of the safety switch 8 is taken out from the IJ control terminal C on the energized side of the motor 5, and a power supply frequency signal Vs, which is used for a timer. Since it is also used as the ON/OFF signal for the safety switch 8, by turning off 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, at the same time as the safety switch 8 is turned off. It is safe because malfunctions are eliminated, the cook is not injured, and the cutting blade 15 is not rotated against the cook's will and the food is not damaged. 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 French CPU42
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 indicates no operation. . Next, & terminal input is 50H
Check whether it is Z or 60HZ, and if it is set to 50HZ, set 2 flags for 50 days. In this way, the initialization operation is performed. Poke, lid 4.

It is determined whether the safety switch 8 is turned on, that is, whether the safety switch 8 is turned on, and if the safety switch 6 is turned on, the
Move to ms counter. Then, it is determined whether the count of the four-shoe force counter is 45hs or more, and if it is not 45mS or more, the power supply frequency signal Vs, to the K8 terminal. is the power supply voltage V. It is determined whether D is at L level or L level. Here, whether it is an H level or an L level, it is determined whether the H level or L level is the first one. In other words, H to the K8 terminal
This detects the zero crossing of the power supply waveform as switching from level to L level and from L level to H level. In this case, if the level remains unchanged, the first H level,
The determination result of whether it is L level is NO, 45ms after 50Hz half cycle other hs and 60Hz half cycle 8.3hs
The counter continues to count up, and when the time reaches 45hs or more, the start flag is cleared and no lid is displayed while the time and speed are memorized. On the other hand, when 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 the 4th flow test, it is determined whether the start flag is 1, and if the start flag is not set, the LED 18 is Move on to the display program. That is, 0
Output from o~06 terminal and Ro~R depending on the digit
Performs dynamic display operations that are output from 3 terminals.
In this case, Ro~R2 in this dynamic display operation
The input signal to the K terminal or the K2 terminal corresponding to the output of the terminal is stored in the RAM, and if there is a signal, it is stored in the 10th terminal described later.
Moving on to the key processing routine shown in the figure. In addition to this dynamic display operation, the display by the LED 18 performs a lighting operation for four digits within a half cycle of the AC power source 33 by carrying up the lighting digit and performing a routine for determining whether four digits are completed. By the way, when the safety switch 8 is OFF, 9
．． 2hs counter, 9.2h which is the intermediate value between 50 days 2 half cycle 1 hs and 60Hz half cycle 8.3ms
4 digits are displayed in s. When the 4-digit display has finished, the input prohibition counter counts each time the routine runs, and if the interval between key inputs is 0.1 seconds or more, a flag is set to remove the input prohibition, and the input prohibition counter is counted. If the voltage buzzer 71 that sounds in response to the input is not ringing, it will pass through as is, but if it is still ringing, the ringing of the voltage buzzer 71 will be cleared in one s. Next, the start flag is 1
If the end buzzer is not sounding, it is determined whether it is the end buzzer. If the end buzzer is not sounding, the process returns to the initial determination of whether the safety switch 8 is ON. These routines form a constant processing routine loop. Next, one processing routine will be explained with reference to FIG.

In the above-mentioned constant processing routine, after storing the input signal to the K terminal or the K2 terminal corresponding to the output from the Ro to R2 terminals in the RAM by operating the dynamic display, if there is a signal, the process moves to this key processing routine. First, when diamond 4 is locked, the power supply frequency signals Vs and G, which are always input to the K8 terminal, are omitted, the lid flag is set to 1, and then the process returns to carrying up the lit digit. and,
When there is an input to the K, terminal or K2 terminal, it is determined whether the input prohibition counter has been canceled based on whether the key interval is 0.1S or more, and if the input is prohibited, the input prohibition counter is cleared. If the prohibition counter has been released, it is determined whether the key press operation is 3 hs or more.This determination is performed in conjunction with the function of the input prohibition counter.
This is effective in preventing chattering of key inputs, uncertain key inputs, or noise entering the AC power supply 33. Thereafter, if the keys are operated for 3 plates or more, a signal is output from the R5 terminal and the transistor 72 is driven to cause the Shoden buzzer 71 to sound. Next, it is determined whether the input is to the K2 terminal or the K2 terminal. Here, if the input is to the K2 terminal, it is determined whether it is the key 25 for auto pulse. In the case of this key 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 pulse signal, etc., and return to carrying the lit digit. If the signal is for a start, the start flag is set to 1 after confirming that continuous operation "C" or the timer is set. 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, clear key 2
If the clear key is 26, return to the start of the program, clear the RAM, and start continuous operation.
C” and the speed is set to “0”. On the other hand, if there is an input to the K terminal, the key 2 "x10" for time setting
If the key is 22, the first digit on the display section 16 is raised.

In other words, if the second digit is x, the key 22
Depending on the operation, it will become ``Gourd'', ``Lx'', ``Koichi...'', and after ``Rscale'', only ``C'' will be displayed, which indicates continuous operation, and the second digit (×1'' digit) will be stored in the 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,
2nd digit x 1" digit on the display section 16). 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.
Furthermore, the ignition processing routine is processed according to FIG. 9 along with the timer processing routine shown in FIG. 11.

First, when the start flag is set, a determination is made as to whether pulse setting is being performed or not based on the determination of the start flag in the regular processing routine. 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.
．． Give a trigger pulse of 38 hS to the triac 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 it is 50Hz, 5 pulses are counted as 1 second, and if it is 60 days 2, 6 solid pulses are counted. 1 second. First, the level of the power supply frequency signal Vs,o is selected, and timer processing is not performed when the signal is at L level, and timer processing is performed only when the signal is 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.If it is not set, it is 60HZ and the 60 counter is entered and counted.This count increases. Then, it is counted by the 4 second repeat counter used for auto pulse or end buzzer.The process up to now is performed in the same way even if continuous operation is set to "C", but if the timer is set, Determine whether the end buzzer is being sounded. If the end buzzer is being sounded, return to the original routine; if not, subtract 1 second from the current time. After the subtraction, the set time elapses and the value becomes 0.
Determine whether the inkstone is covered or not. If there is still time left, return to the original routine, and if it is 00 seconds, set the end buzzer, clear the start flag, and return to the original routine. If the speed is set to something other than "6", the set speed is set to "1" or "1" after determining whether the start flag is up and determining whether the speed is "6" or pulse setting.
5" is called from the RAM.

Here, at 50 days 2 or 60Hz, even if the firing time is the same from the zero cross point, the firing angle will be different.
Determine whether the 50HZ flag is on and set 5 for each.
The 50Hz firing angle force counter is selected so that the same power consumption can be obtained depending on 0Hz and 60Hz, and the 2-point firing angle force counter is counted on 60 days, and the firing angle pulse that becomes the set speed is calculated by the triac 35 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, it is further determined whether the end buzzer is within 2 seconds, and the contents of the 4 second repeat counter in the timer processing routine are checked.
If the time has passed for 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 is "x, x, 1, P", but when the speed is "6", 2
It will be a line return of running for 2 seconds and pausing for 2 seconds.

Therefore, if the pulse setting is set, the pulse counter, that is, the 4-second repetition counter, first determines whether it is the operating time or the rest time. If it is a running time, an ignition pulse is given as in the case of speed "6", and if it is a rest time, a timer processing routine is called to advance the timer.
Cooking according to the settings is performed by these constant processing routine, key processing routine, ignition processing routine, and timer processing routine.

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 by turning the safety switch 8 ON or OFF. Next, keys 22 and 23
Set the time by operating . This setting range is 00~
9. If there is no operation, continuous operation will be "C". For example, if you want to set 39 seconds after displaying "roo" seconds, press the "x10" key 22 three times, press the "x1" key 23
If you press 9 times, the display as shown in Figure 12b will appear. If you want to change the time set in this way, you can do so by continuing to operate the keys 22 and 23 or by clearing the time using the clear key 26 and resetting it.
Then, the speed is set by operating the key 24. That is, the speed is set in stages "0" to "6" depending on the number of times the button is pressed. For example, if the key 24 is pressed five times, a speed of "5" will be set and displayed as shown in FIG. 12c. This speed change is performed on the same aircraft. 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 on the 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.
Even if I repeat step 7, it doesn't 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 4 is removed, only the lid display is 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 manner, when the start/stop key 27 is pressed, the motor 5 is started and cooking begins. At this time, the time displayed on the display section 16 is displayed subtracting one second at a time as time passes. ·and,
When the remaining time reaches 00 seconds, the piezoelectric buzzer 77 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 in the middle of operation, you can use the start button.
Just press the stop key 27 again. By this operation, the start/stop key 27 acts as a stop key, the motor 5 is stopped, and the remaining time (or "C") and speed at that point are fixedly displayed on the display section 16. If you want to resume operation, press the start/stop key 2 again.
Just press 7 once. 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. Also, if you want to operate intermittently, press key 24.
Instead of setting the speed by operating the key 25, pulse setting may be performed using the key 25.

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 "00" 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
As shown in FIG.

As a result, as time passes, the display will be subtracted by 1 second and will be displayed as 0.
When it becomes sand, 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 is provided with a display section that displays the operating time, operating speed, and when the safety switch has been turned on at the same location, so just by looking at the display on this display section, you can check the setting status, the lid installation status, etc. It is possible to know all the conditions of the cooking appliance, such as the condition of the power outlet, and to improve the cooking procedure.
