Description

Description: TECHNICAL FIELD The present invention relates to a control device, such as a device with a timer, provided with a numerical display for displaying a set time for timer operation.

[Prior Art] For example, a device with a timer is equipped with an operation switch for setting the operation time of the timer and a numerical indicator for displaying the operation time according to the setting state of the operation switch. When you operate a switch etc., the timer operates and the device operates for the time displayed on the numerical display.

In this case, depending on the operation state of the operation switch, for example,
If the operation time of the switch is less than a predetermined short time (for example, 0.5 seconds), the set time is changed by unit time, and if the operation time of the switch is longer than the predetermined short time, the set time is changed. It can be changed continuously at fixed time intervals.In this case, the fixed time is determined to be shorter than the predetermined short time, and the set time is changed at short intervals.
The change speed is increased, and the time required to change to the desired set time is shortened.

[Problems to be Solved by the Invention] As described above, in the related art, in order to prevent the operation time of the switch when setting the timer or the like from being long, the setting time is changed when the switches are continuously operated. The speed is high, and at this time, the numerical value displayed on the numerical display is also changed at a high change speed according to the set time.

For this reason, it becomes difficult to read the displayed value, and it becomes difficult to stop the display at the target value.Therefore, the target value may be exceeded, and it takes time to return and set. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to be able to easily read a displayed numerical value and easily set a target numerical value in a short time in a control device equipped with a numerical display.

[Means for Solving the Problems] The present invention is directed to a switch that is pressed, a control numerical value setting unit that sets a control numerical value of a device according to the operation of the switch, and a setting by the control numerical value setting unit. In the control device of the device having a numerical notation for displaying the control numerical value, the control numerical value setting means, when the pressing operation continuation time of the switch is within a predetermined time, every pressing operation. If the control numerical value is changed by a first unit number and set, and the pressing operation duration of the switch exceeds the predetermined time, the control numerical value is set to the first numerical value every predetermined elapsed time. The technical means is to change and set the second unit number larger than the unit number.

[Operation] In the present invention, when the operation duration of the switch is within the predetermined time, the control numerical value is changed and set by the first unit number, and when the predetermined time is exceeded, the second unit number is set. Is changed one by one.

At this time, the numerical value displayed on the numerical display is the set numerical value, and the changing speed thereof is every predetermined elapsed time, and only the magnitude of the numerical value changed at each predetermined elapsed time is the first.
To a second number of units greater than the number of units of.

Therefore, the displayed numerical value does not become difficult to read.

EFFECTS OF THE INVENTION In the present invention, if the switch is operated for a predetermined time,
The set control numerical value can be changed by the second unit number larger than the first unit number.

At this time, the displayed numerical value simply corresponds to the control numerical value that is set and is not changed one after another in a short time as in the conventional case, so that it is easy to read.

Therefore, it is easy to read the displayed control numerical value and stop the switch operation when it is close to the target control numerical value, and then repeat the switch operation within the predetermined time to change the first unit number. The desired control value can be set to.

Therefore, even if the target control value is large, the time required to set the control value is shortened.

It is necessary to place the gas stove 2 on the Gotoku 2d and ensure that the cooking container L and the temperature sensor 2 are in contact with each other.

Hereinafter, the control operation when the gas stove 2 is used in the table stove 1 will be described.

(1) Temperature control operation As described above, when the cooking vessel L is placed on the Gotoku 2d and the temperature control switch 11 is pressed, the operation lamp 11a lights up, and the numerical display 20 shows the temperature control operation at the time of the previous temperature control operation. A numerical value indicating the set temperature is displayed.

When the temperature setting switch 12 or the temperature setting switch 13 is operated while observing the displayed numerical value, the displayed numerical value changes accordingly, and when the change is stopped, the operation starts as the set temperature of this time.

(2) Stew timer operation When the stew set switch 14 is pressed, the operation lamp 14a lights up, and the numerical display 20 displays three "0".

When setting the time to 1 hour or more, the hour setting switch
When 15 is pressed, “1” is displayed on the numerical display 20.

After that, if the hour setting switch 15 is repeatedly pressed as needed, the displayed number is incremented by one.

When the displayed numerical value reaches the target number of hours, when the operation of the hour setting switch is completed, the setting for the time unit is completed.

The maximum number of hours that can be set here is "4". If the set value is mistakenly set higher than the target value, further operation of the hour setting switch 14 will cause the next number of "4". “0” is displayed again on the screen and can be set again.

On the other hand, when the set time is 1 hour or more and the minute is also designated, or when the set time is less than 1 hour, the minute setting switch 16 is operated.

When operating the minute setting switch 16, as shown in FIG. 1, a two-step carry-up operation is performed.

The setting operation of the set time will be described below.

If the minute setting switch 16 is not operated and is off (NO in step 1), it is in a standby state until it is turned on, and if the minute setting switch 16 is operated and is on (step If YES in 1), the first timer is operated (step 2), and the first advance operation is performed (step 3).

The first advance operation is, as shown in FIG. 6, a set value t
It is determined whether or not the minutes are t ≧ 59. If t ≧ 59 (YES in step 21), the minutes are reset and returned to 0 (step 22).

On the contrary, when t <59 (NO in step 21), the fraction is moved up by 1 (first unit number) (step 2
3).

When the first raising operation is finished, it is judged whether or not the operation of the minute setting switch 16 is finished, and when the operation of the minute setting switch 16 is finished and turned off (YES in step 4), the first The timer is cleared (step 5), the process returns to step 1 and waits again until the minute setting switch 16 is operated.

If the minute setting switch 16 has not been operated (NO in step 4), the operating time T ₁ of the first timer (about 0.
It is determined whether or not 5 seconds) has elapsed, and when the operation time T ₁ has elapsed (YES in step 6), the operation of the second timer is started (step 7).

On the contrary, when the operation time T ₁ has not elapsed (NO in step 6), the process returns to step 4 and waits until the operation time T ₁ elapses, during which the operation of the minute setting switch 16 ends. If so, the process proceeds to step 5.

Even after starting the operation of the second timer, the minute setting switch 16
It is determined whether or not the operation of
If the operation has been finished and turned off (YES in step 8), the second timer is cleared (step 9), the process returns to step 1 and waits until the minute setting switch 16 is operated again.

When the operation of the minute setting switch 16 is not completed (NO in step 8), the operation time T ₂ of the second timer (about 0.
3 seconds) has elapsed, and if the operation time T ₂ has not elapsed (NO in step 10), the process returns to step 8 and waits until the operation time T ₂ elapses, during which When the operation of the minute setting switch 16 is completed, the process proceeds to step 9.

If the operating time T ₂ has elapsed (in step 10, YE
S), the second advance operation is performed (step 11).

In the second carry-up operation, as shown in FIG. 7, the fraction t (t = 10 × m + n) as the set value is discriminated according to the tens digit m and the ones digit n. , N <5
In the case of (YES at step 31), the numerical value n of one's place is temporarily raised to 5 (step 32).

On the contrary, when n ≧ 5 (NO in step 31), the ones digit n is once replaced with 0 (step 33), and when the tens digit m is m ≧ 5 (step 34). At YE
S), replace the tens digit m with 0 (step 35),
When the tens digit m is m <5 (NO in step 34), the tens digit m is advanced by 1 (step
36).

As a result, the number n in the first place of the displayed number is "0-4".
In the case of, "5" is displayed once, and if it continues after that, it is incremented by "5 (first number of units)", and similarly, the numerical value n of the one digit displayed is " In the case of "5-9", "0" is once displayed and the tens place is moved up by one.

Therefore, when the second advance operation is performed, the set time displayed every 5 minutes is 5 minutes depending on the operation duration of the minute setting switch 16 after the end of the operation time of the first timer. It will increase in steps.

After the second carry-up operation, the process returns to step 7 and the same processing is performed.

In the simmering timer operation, after heating starts, heating is continued until the detected temperature reaches 95 ° C, and when it reaches 95 ° C, the timer operation starts according to the set time set by the above operation, and the set time elapses. Then, the heating is stopped. During this time, the heating temperature is controlled and maintained at 95 ° C.

If you set the time by operating the hour setting switch 15 or the minute setting switch 16 without operating the simmering set switch 14, the heating temperature and heating time are not controlled, and when the set time elapses, a buzzer sounds. Notify.

(3) Boiling control When the temperature sensor 2b detects boiling, the heating is automatically stopped.

(4) Rice cooking control While detecting the temperature by the temperature sensor 2b, the amount of heating is controlled with time based on a pre-installed program to perform automatic rice cooking.

Next, the relationship between the set time and the minute setting switch 16 for the boiling operation in this embodiment will be described with reference to FIG.

For example, if you want to set 37 minutes as the boiling time, turn on the minute setting switch 16
When is turned on, the first advance operation is performed and the set value becomes 1 minute.

When the minute setting switch 16 is turned on continuously, the second carry-up operation is performed every 0.5 seconds, and then every 0.3 seconds, 5 minutes, 10 minutes, 15
Minutes ... 30 minutes, 35 minutes.

During this time, the numerical value displayed on the numerical display 20 changes sequentially, but since the speed of change is every 0.3 seconds, the displayed value is 3
If the operation of the minute setting switch 16 is stopped at the time of 5 minutes, it can be sufficiently stopped before the set value is advanced to 40 minutes.

After that, set the minute setting switch 16 to 2 within 0.5 seconds.
If it is turned, the first advance operation is performed twice, and the set value can be set to 37 minutes.

As described above, in the present embodiment, even if the set time for the timer operation is continuously set for each unit number, the set numerical value is set to be larger than the unit number by continuing to operate the minute setting switch. Since it can be changed at intervals, it can quickly approach the target set value.

At this time, it is not necessary to perform a troublesome operation on the minute setting switch, and the minute setting switch can be kept pressed, so that the operation does not take time.

In addition, the numerical value displayed at this time corresponds to the set numerical value and changes at a speed that is sufficiently visible, so if you check the displayed numerical value and then operate it, it will remain as it is displayed. Numerical values can be set numerical values.

Therefore, the target numerical value can be set quickly and reliably.

In the above embodiments, the gas table is shown as an example, but other devices such as a cooking device such as a microwave oven and an oven, and a heater and a heat retaining device may be used.

Further, although the set numerical value is used for the timer operation, it may be used as the set temperature of the water heater, various heaters and the like.

Alternatively, it may be used as a numerical value display plate for simply displaying numerical values.
