Description

Detailed Description of the Invention [Purpose of the Invention (Industrial Application Field) The present invention provides a method for performing operation based on a demonstration operation mode for showing the contents of the operation, in addition to executing operation based on a normal operation mode. The present invention relates to an electronic device with a demonstration function capable of performing.

(Prior Art) Various electronic devices of this type are available, and a rice cooker is a well-known example. Conventional rice cookers are equipped with an operation control circuit that has a normal operation mode and a demonstration operation mode as operation modes, and are equipped with one or more switches such as a timer switch, rice cooking switch, heat retention switch, and cancel switch as external input means. When performing normal operation, based on the normal operation mode, the timer function operates the timer, the heater drives the rice cooking operation, and the warming operation is performed, and the set time and remaining time of the timer are displayed on the display and alarm, etc. Normal operation is performed, such as displaying the display and displaying and informing the driving status in accordance with each operation. On the other hand, when displaying the rice cooker at a store, etc., based on the demonstration operation mode, the heater is not driven, the timer function is increased, and the display and alarm are used to simulate the operation in the normal operation mode. I try to carry out the operation shown.

(Problem to be Solved by the Invention) Conventionally, demonstration operation modes include a continuous mode in which the operation contents of normal operation are automatically and repeatedly shown, and a continuous mode in which the operation contents are displayed using appropriate operating means. There is a single mode in which the operation is shown in a single manner.Demonstration operation in the continuous mode is suitable for showing the operation details of normal operation to unspecified customers. Demonstration operation in a single mode is suitable for explaining the operation details.

However, as a demonstration driving mode,
Conventionally, only one of the continuous mode and single mode has been available, and the actual situation has been that the display effect in stores etc. has been low. Recently, as a countermeasure to this problem, when performing demonstration operation in continuous mode, the demonstration operation is first performed in continuous mode, and then the repetitive operation is stopped at that point by operating an appropriate operating means, and sometimes the operation is performed in single mode. There is a specification that only stops the demonstration operation in continuous mode at the point of operation, but cannot single-handedly indicate the next operation content, and then restarts the demonstration operation in continuous mode. In this case, there is a problem in that the demonstration operation mode must be set again, which makes it inconvenient to use.

The present invention has been made in view of the above circumstances, and within the same day, when the demonstration operation mode is set, it is possible to select either continuous mode or single mode, and to switch between them. An object of the present invention is to provide an electronic device with a demonstration function that can be performed extremely easily.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an operation control circuit having a normal operation mode and a demonstration operation mode as operation modes;
An external input means for supplying control information to the operation control circuit is provided, and in addition to executing normal operation based on the normal operation mode by operating the external input means, operation contents of the normal operation mode are executed based on the demonstration operation mode. The demonstration operation mode is a continuous mode for continuously and repeatedly demonstrating the operation contents of the normal operation mode, and the operation contents are shown in a single manner. causing the operation control circuit to have a single mode for
When the demonstration operation mode is set, the continuous mode is initially set and executed, and the presence or absence of an operation of the external input means is determined, and if there is such operation, the 111-mode is selected and executed. However, when the operation is canceled and a predetermined time has elapsed, the continuous mode is selected and executed.

(Operation) When the demonstration operation mode is set, the continuous mode is normally selected and executed.

Therefore, when selecting and setting the single mode, the single operation mode is set and executed by operating the external input means, and if the operation is continued, execution in the single mode is performed. will also be continued. Thereafter, when a predetermined period of time has elapsed after the operation was canceled, the continuous mode is selected and executed in place of the single mode. Therefore, the continuous mode and the single mode are selectively executed as necessary, and each mode is switched depending on whether or not the external input means is operated, so switching between each mode is extremely easy. be.

(Example) An example in which the present invention is applied to a rice cooker will be described below with reference to the drawings.

First, in FIG. 1, 1 is a commercial AC power supply, 2 and 3 are heaters, 4 is a relay switch for cooking rice, and 5 is a relay switch for keeping warm. 6 is a step-down transformer, and 7 is a DC constant voltage circuit. 8 is an operation control circuit composed of, for example, a microcomputer, which has a normal operation mode and a demonstration operation mode as an operation program, and also has a continuous mode and a single mode as its demonstration operation modes, Its output is controlled to execute the operation based on the human power signal given to it and each set mode. The human power port of this operation control circuit 8 is connected to a switch input circuit 9. Demonstration operation mode setting circuit 10. A human input signal is provided from the temperature detection circuit 11, and a display circuit 12. Rice cooking relay drive circuit 13. Output signals are provided to the heat retention relay drive circuit 14 and the alarm drive circuit 15. On the other hand, FIG. 3 shows an operation panel 16, and in FIG. 3 and FIG. 1, the switch input circuit 9 is replaced by the rice cooking switch 17, which is the external input means shown in FIG. Heat retention switch 18. It is configured with a timer switch 19 and a cancellation switch 20. Each of these switches 17 to 20
The operation control circuit 8 is configured to detect a change from OFF to ON, a change from ON to OFF, and the presence or absence of an OFF state for the input of each switch 17 to 20. It has become. The demonstration operation mode setting circuit 10 is formed by connecting a jumper wire 21 and a resistor 22 in series, and outputs a high level setting signal when the jumper wire 21 is present, and outputs a low level signal when the jumper wire 21 is removed. Output. The jumper wire 21 is present when the rice cooker is displayed at a store or the like, and is removed when the rice cooker is sold to general users. The temperature detection circuit 11 detects the rice cooking temperature and the warming temperature and outputs the detected temperature data. The display circuit 12 is composed of four-digit seven-segment light emitting diodes 23 shown in FIG.

The rice-cooking relay drive circuit 13 and the heat-retaining relay drive circuit 14 turn on and off the respective relay switches 4 and 5, and the alarm drive circuit 10 controls the drive of an alarm (not shown) by turning off the power. It is.

The operation control circuit 8 sets the operation program to the demonstration operation mode when the output signal from the demonstration operation mode setting circuit 10 is at a high level, and sets the operation program to a normal operation mode when it is at a low level. Here, to roughly explain the normal operation (actual rice cooking operation performed by the user) when the jumper wire 21 of the demonstration operation mode setting circuit 10 is removed and the normal operation mode is set, When the light emitting diode 23 is turned on, first, as shown in FIG. 4(a), the light emitting diode 23 flashes in a "rorororo" display format. After this, the rice cooking mode changes to "timer cooking", "cooking", and "keep warm" based on each operation of switches 17 to 20.
carried out in one of the following courses. Each of these courses will be described below.

■"Timer cooking": First, turn on the timer switch 19. Based on this change of the input of the switch 19 from OFF to ON, the light emitting diode 23 is turned on as shown in FIG.
), it flashes in a display format of "10 units", and the minimum time of the timer time is displayed, and the timer time can be set. After this, timer switch 1 again
When 9 is turned on, the blinking display of the light emitting diode 23 is changed to a lighting display based on the change from off to on.
The timer time is updated and set according to the duration of the ON operation or the number of ON operations, and the set time is displayed on the diode 23 each time. In this case, the set timer time is the time until the end of the rice cooking operation. When the rice cooking switch 17 is turned on after this setting, the timer operation by the timer function is started, and the remaining time until the end of the rice cooking operation is sequentially displayed on the light emitting diode 23 (
An example of this is shown in FIG. 4(C)), and when the set timer time has elapsed, the rice cooking operation is started. In this rice cooking operation, the rice cooking relay drive circuit 13 is appropriately controlled based on the detected temperature data from the temperature detection circuit 11, and thereby the heater 2 is controlled to be turned on and off as appropriate. During this rice cooking operation, the most significant digit of the light emitting diodes 23 is displayed in a "mouth" display form as shown in FIG. 4(d). When this rice cooking operation ends substantially at the same time as the timer setting time expires, an alarm (not shown) is driven by the alarm drive circuit 15. After this, the heat retention operation is executed. This heat retention operation is executed by appropriately controlling the heat retention relay drive circuit 14 based on the detected temperature data from the temperature detection circuit 11, and thereby controlling the heater 2.3 to be turned on and off as appropriate. During this heat retention operation, the lowest digit of the light emitting diode 23 changes as shown in FIG. 4(e).
It is displayed in a display format called "mouth".

■ "Rice Cooking": The rice cooking switch 17 is turned on from the beginning without turning on the timer switch 19. Based on the change from off to on, the rice cooking operation described above is first started. In this rice cooking operation, the heater 21, light emitting diode 23, and alarm are driven similarly to the rice cooking operation described above.

After this period has elapsed, the same heat-retaining operation as described above is performed. In this heat retention operation, the heaters 2 and 31 and the light emitting diode 23 are driven in the same manner as described above.

■“Keep warm”: Turn on the keep warm switch 18. Based on the pit change from off to on, the heat retention operation is started and continued with the heaters 2 and 3 and the light emitting diode 23 being driven in the same way as described above.

If the cancel switch 20 is turned on, the operation is stopped at that point, and the light emitting diode 23 is turned on as shown in FIG.
The light is turned off as shown in f). Further, when each of the switches 17 to 20 is turned on, the alarm drive circuit 15 drives the alarm and outputs an alarm sound.

Now, a case will be described in which a demonstration operation is performed based on the demonstration operation mode. In advance,
The contents of continuous mode and single mode will be described.

In the continuous mode, the operation contents of the above-mentioned "timer operation" are repeatedly shown in a simulated manner by speeding up the timer time without driving the heater 2.3. In this case, the timer setting time is uniquely 84 seconds (the timer time for normal operation is 600 times faster, which is 14 seconds faster than normal operation).
2 seconds before the end of the remaining time display, and displays the rice cooking operation as described above two seconds before the remaining time display ends. The operation display is executed for 2 seconds, and when the timer reaches the 84-second timer, the alarm is driven, and then the warming operation display is executed for 2 seconds, and these are repeated continuously.

In addition, in the single mode, any of the normal operation modes of "timer cooking", "cooking", and "keep warm" is displayed in a simulated manner; The selection is made by operating each of the switches 17 to 21 in the same manner as in the normal operation described above.

Therefore, in order to simulate "timer rice cooking," the timer time was set using the timer switch 19]; When the rice cooking switch was turned on, the operation content of "timer rice cooking" was changed to the remaining time of the above 600x speed. On the display, the rice cooking operation is displayed for 222 seconds, the alarm is activated, and then the warming operation is displayed without any time limit. Further, when "rice cooking" is selected by operating the rice cooking switch 17, a rice cooking operation is displayed for 2 seconds, and a warming operation without any time limit is displayed. Furthermore, when "keep warm" is selected by the keep warm switch 18, a keep warm operation display with no time limit is displayed. Incidentally, when the cancel switch 20 is operated, an operation stop display (shown in FIG. 4(f)) is displayed.

Now, assuming that the jumper wire 21 is present in the demonstration operation mode setting circuit 10, when the power is turned on, the operation control circuit 8 executes the operation program according to the flowchart shown in FIG.

That is, when the power is turned on, first, in step Sl, it is determined whether the output from the demonstration operation mode setting circuit 10 is at a high level, that is, whether the jumper wire 2
In this case, since the jumper wire 21 is present, the process moves to steps S2 and S3 according to rYESJ of step S1, and in step S2, the demonstration operation mode (this is the operation mode to be executed) is determined. 2 is referred to as the convenient up-driving mode), and step S3
Now, we will set continuous mode as this demonstration operation mode. In this case, the initial setting is continuous mode. Next, the process moves to step S4, where it is determined whether or not the driving mode is the demonstration driving mode. In this case, since it is the demonstration driving mode, step SS is performed according to rYEsJ of step S4.
Then, it is determined whether the demonstration operation mode is the continuous mode, and in this case, since the continuous mode has been selected and set in step Ss, the process moves to step S6 according to rYEsJ of step S. . In this step S6, continuous mode is executed. This continuous mode is executed on the condition that the switches 17 to 20 are not operated or released as shown in steps 57 and S8. That is, step S
In step S7, it is determined whether any of the switches 17 to 20 has changed from off to on a number of times, that is, whether any switch has been turned on, and if there is no such operation, the process moves to step S8. Then, it is determined whether the switch input of any one of the switches 17 to 20 has changed from on to off, that is, it is determined whether the operation has been released, and if there is no release of the operation, the process proceeds to step S4. Return to Therefore, if the switches 17 to 29 are not newly operated from off to on and the operation is not released, step S
4→Step Ss→Step S6→Step sr→Step S8→Step S4, and so on.

As a result, this continuous mode (step Ss) allows the remaining time to be displayed at 600x speed as described above.

Operations indicating the operation contents, such as displaying rice cooking operation for 122 seconds, driving the alarm, and displaying heat retention time for 2 seconds, are performed continuously and repeatedly.

Here, if any of the switches 17 to 20 is turned on and there is a change in the switch input from off to on, step S
9, and in this step SS, it is determined whether the mode being executed at this point is the continuous mode. In this case, since it is the continuous mode, the process moves to step SIO according to rYESJ, and this step S1G Then, the execution mode is switched to the 1lj-mode, and then in step Stt, an operation based on the switch being manually turned on (for example, an initial blinking operation of the light emitting diode 23 based on turning on the timer switch 19, etc.) is executed. After this, the process returns to step S4, and in this step S4, the rYEs
According to J, the process moves to step S5. This step S5
Then, as described above, it is determined whether the execution mode at this point is the continuous mode or not. In this case, since it is the single mode, the process moves to step S12 according to rNOJ of this step S5, and in this step S12, A determination is made as to whether the operated switch is in an off state. Since it is in the on state at this point, the process moves to step 313 according to "NO". In this step S13,
"" selected by each switch 17 to 20
A single mode of "timer rice cooking", "rice cooking", "warming", and "operation stop" is executed, and then the process moves to the next step S. In this step S7, it is determined whether or not there is a change in the human power of each switch 17 to 20 from off to on, but at this point the switch is already in the on state (change to on is not detected), so this step ST
The process moves to step SB according to rNOJ. Therefore,
If the on state of each switch 17 to 20 is maintained, step S → step S8 - step S4 → step S5 → step 512 - step S13 → step S
, and so on, and single mode execution continues. Here, if the on-operation state of the switch is released, that is, if the switch input changes from on to off, the process moves to step 314 according to rYESJ in step S8, and it is determined whether the driving mode is the demonstration driving mode or not. In this case, since it is the demonstration operation mode, step S is performed according to the rYESJ.
Shifting to XS, the count value of the auto-start counter is cleared, and in the next step 818, the operation performed based on the switch being turned off (for example, displaying the set time of the timer time based on the turning off of the timer switch 19, etc.) is executed. Then, the process moves to step S4→step S,→step S1□. In this step S12, since the switch is already in the off state after the switch is turned off, the process moves to step sty according to rYESJ. In this step sty, it is determined whether the execution content of the single mode is setting the timer time, displaying the heat retention operation, or displaying the operation stop, and if it is any of the above, the process proceeds to the next step 5111. Then, in step S19, it is determined whether the count value is less than 30 seconds, and if it is less than 30 seconds, the process proceeds to step 513. Then, step Sτ → step S8 → step S4 → step S, → step 312 → step sty
→Step 318→Step 819→Step S13→
Go through a loop such as step S. That is, the execution of the single mode is continued on the condition that the count time does not exceed "30 seconds" and there is no new switch-on operation. Then, when the above r3Q seconds have elapsed, step S
According to "NO" in tS, the process returns to step S3, and the continuous mode is automatically executed again.

The reason for setting the time limit of 30 seconds is as follows. First, setting the timer time.

If there is no human power to turn on the switch while the heat retention operation is displayed or the operation is stopped, it is assumed that the store has finished explaining to the customer, and regarding the remaining time display. The reason for not having a time limit of "30 seconds" is that in this single mode, if "timer cooking" is set for a set time of 14 hours, it will take 84 seconds before the set time of 14 hours expires. This is because it takes a long time of seconds (600 times the speed), and there is a possibility that the rice cooking operation display that should be done two seconds before the time-up of "84 seconds" and the warming operation that should be done after that will not be executed.

When the jumper wire 21 of the demonstration operation mode setting circuit 10 is removed, the process moves to step S7 via step S1 → step 820 → step S4 → step S21, and thereafter each switch 17 to 20
Normal operation is performed based on the normal operation mode according to the operation.

In the above embodiment, a microcomputer is used as an example of the operation control circuit, but it may also be configured with hardware logic. Further, in the above embodiment, the jumper wire 21
Although the demonstration operation mode and the normal operation mode are selectively set depending on the presence or absence of the vehicle, the selection setting is not limited to this. Furthermore, although a rice cooker was illustrated in the above embodiment, the present invention can be widely applied to all electronic devices with demonstration functions.

The pond water invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the gist.
