Abstract

PURPOSE:To shorten the time required to set an objective numerical value and to easily read it even at the time when this value is large by changing the set numerical value by a prescribed number larger than a unit number at the time of operating a switch over a prescribed time. CONSTITUTION:This controller is provided with a numerical display device 20 on which the numerical value continuously set with a prescribed unit number as the unit in accordance with the operation state of a switch 16 is displayed, and the numerical value is changed by the prescribed unit number when the operation time of the switch 16 is equal to or shorter than a prescribed time, but it is changed by not only the unit number but also a prescribed numerical value when it exceeds the prescribed time. The numerical value displayed on the numerical display device 20 is the set numerical value at this time, and the change speed is not especially changed but only the magnitude of the changed numerical value is increased. Thus, the displayed numerical value is prevented from being difficult to read.

Description

DETAILED DESCRIPTION OF THE INVENTION [8.Field of Industrial Application] The present invention relates to a control device, such as a device equipped with a timer, that is equipped with a numerical display for displaying the set time of the timer operation, etc.

[Prior Art] For example, a device with a timer is equipped with an operating switch for setting the operating time of the timer, and a numerical display that displays the operating time according to the setting state of the operating switch. When a switch is operated, a timer is activated, and the device operates for the time indicated on the numerical display.

In this case, depending on the operation state of the operation switch, for example,
The switch operation time is a predetermined short time (e.g. 0.5 seconds)
In the following cases, the set time can be changed in units of time, and if the switch operation time is continuous operation longer than a predetermined short time, the set time can be changed continuously at fixed time intervals, and in this case, the set time can be changed continuously in units of time. Since the time is determined to be shorter than the predetermined short time mentioned above, and the set time is changed at short intervals, the speed of change is faster and the time required to change to the desired set time is shortened. There is.

[Problems to be Solved by the Invention] In this way, conventionally, in order to prevent the operation time of a switch from becoming too long when setting a timer, etc., when a switch is operated continuously, it is necessary to change the setting time. The speed is increasing, and at this time, the numerical value displayed on the numerical display is also changed at a fast changing speed corresponding to the set time for changing.

As a result, it becomes difficult to read the displayed value, and it becomes difficult to stop the display at the desired value, resulting in the problem of exceeding the desired value and taking a long time to set it. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a control device equipped with a numeric display that allows the displayed numeric values to be easily read and to easily set a desired numeric value in a short time.

[Means for Solving the Problems] The present invention provides a control device equipped with a numerical display that displays numerical values that are continuously set for each predetermined number of units according to the operating state of the switch. If the operation time is within the predetermined time, the set value is changed by the number of units, and if the operation time to the switch exceeds the predetermined time, the set value is changed according to the operation time. The technical means is to change the numerical value by a predetermined number larger than the unit number.

[Operation] In the present invention, if the switch operation time is within a predetermined time, the numerical value is changed and set by a predetermined number of units, and if the predetermined time exceeds the predetermined time, in addition to changing the number of units, the numerical value is set. It is changed by a predetermined value.

At this time, the numeric value displayed on the numeric display is the set numeric value, and the speed of change does not particularly change, and only the size of the changed numeric value increases.

Therefore, the displayed numerical values will not become difficult to read.

[Effects of the Invention] In the present invention, if the switch is made for more than a predetermined time,
The set numerical value can be changed by a predetermined number larger than the unit number.

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

Therefore, while reading the displayed value, you can easily set the desired value by simply stopping the switch operation when it gets close to the desired value, and then repeating the switch operation within a predetermined period of time to change the number of units. be able to.

Therefore, even if the desired numerical value is large, the time required to set the numerical value is shortened.

Furthermore, regarding the gas stove 2, in order to control the temperature adjustment operation, timer operation, etc., as described above, the stove control section 31 includes a temperature adjustment control section 34, a timer control section 35, a boiling control section 36, a rice cooking control section There is section 37. In addition, when performing control by these control units, in order to detect the temperature of each object to be cooked by the temperature sensor 2b, the bottom of the cooking container should be in contact with the temperature sensor 2b, as shown in FIG. It is necessary to place the cooking vessel on the trivet 2d of the gas stove 2 to ensure that the cooking vessel and the temperature sensor 2b are in contact with each other.

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

(1) Temperature control operation As mentioned above, when the cooking container is placed on the trivet 2d and the temperature control switch 11 is pressed, the operation lamp 11a lights up and the numerical display 20 shows the information from the previous temperature control operation. A numerical value indicating the set temperature will be displayed.

When the temperature setting switch 12 or temperature setting switch 13 is operated while looking at the displayed value, the displayed value changes accordingly, and when the change is stopped, operation starts with the current set temperature.

(2) Stew timer operation When the stew set switch 14 is pressed, the operation lamp 14a lights up and three "O"s are displayed on the numerical display 20.

If the set time is to be one hour or more, when the hour setting switch 15 is pressed, "1" is displayed on the numerical display 20.

Thereafter, when the hour setting switch 15 is pressed repeatedly as necessary, the displayed number is incremented by one.

When the displayed value reaches the desired number of hours and the operation of the hour setting switch is completed, the setting of the hour unit is completed.

The maximum number of hours that can be set here is r4-1, and if the set value is accidentally set larger than the desired value, by further operating the hour setting switch 14, the number of hours can be set to r4-1.
"0" will be displayed again next to "0" and you can set it again.

On the other hand, if the set time is one hour or more and the minutes are also specified, or if the set time is less than one hour, the minute setting switch 16 is operated.

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

The setting operation of the setting time will be explained below.

If the minute setting switch 16 is not operated and is off (No in step 1), it remains in a standby state until it is turned on; if the minute setting switch 16 is operated and turned on (step 1))
, activates the first timer (step 2), and performs the first incrementing operation (step 3).

In the first increment operation, as shown in FIG. 6, it is determined whether or not t≧59 when the set value is changed to a minute. If t≧59 (YES in step 21), the fraction is reset and O (step 22).

Conversely, in the case of 59 (NO in step 21)
), round up the fraction by 1 (step 23).

When the first advance operation is completed, it is determined whether or not the operation of the minute setting switch 16 has been completed, and the minute setting switch 16 is
If the operation has been completed and the minute setting switch 16 is turned off (YES in step 4), the 1st timer is cleared (step 5), the process returns to step 1, and waits until the minute setting switch 16 is operated again.

If the operation of the minute setting switch 16 is not completed (
No in step 4) - operating time TI of the first timer
(approximately 0.5 seconds) has elapsed, and if the activation time T has elapsed (YES in step 6).
), the second timer starts operating (step 7).

Conversely, if the operating time T, has not elapsed (NO in step 6), the process returns to step 4 and the operating time T,
If the operation of the minute setting switch 16 is completed during that time, the process moves to step 5.

Even after starting the operation of the second timer, the minute setting switch 1
It is determined whether or not the operation in Step 6 has been completed, and if the minute setting switch 16 has been operated and turned off (YES in Step 8), the second timer is cleared (Step 9), and the second timer is cleared (Step 9). Go back to minute setting switch 1 again.
Wait until step 6 is performed.

If the operation of the minute setting switch 16 is not completed (
NO in step 8), second timer operation time T2
(approximately 0.3 seconds) has elapsed, and if the operating time T2 has not elapsed (No in step 10), return to step 8 and wait until the operating time T2 has elapsed. However, if the operation of the minute setting switch 16 is finished during that time, the process moves to step 9.

If the operating time T2 has elapsed (YES in step lO), a second raising operation is performed (step 1).
1).

In the second rounding operation, as shown in Fig. 7, the fraction t (t=10Xm+n) as a set value is determined according to the numerical value m in the tens place and the numerical value n in the - place, and n
If <5, then YES in step 31) - Carry the ones place number n to -95 (Step 32)
.

Conversely, if n≧5 (NO in step 31)
, temporarily replace the negative digit n with O (step 33)
, when the numerical value m in the tens place is m≧5 (YES in step 34), the numerical value m in the tens place is also replaced with O (step 35), and when the numerical value m in the tens place is m<5, (NO in step 34), the tens digit m is incremented by 1 (step 36).

As a result, the numerical value n in the negative place of the displayed number is “0~41
In the case of , "5" is displayed once, and if it continues after that, it is incremented by "5", and similarly, if the number n in the - place of the displayed number is "5 to 9", "O" is displayed once, and the tens digit is moved up by 1.

Therefore, when performing the second advance operation, the set time is displayed every 0.35 seconds depending on the duration of operation of the minute setting switch 16 after the end of the first timer's operating time. It will increase by 5 minutes.

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

In the simmering timer operation, the detected temperature is 95℃ after heating starts.
When the temperature reaches 95° C., a timer operation is started according to the set time set by the above operation, and when the set time has elapsed, heating is stopped.

During this time, the heating temperature is controlled and maintained at 95°C.

Note that if you set the time by operating the hour setting switch 15 or minute setting switch 16 without operating the stew setting switch 14, the heating temperature and heating time will not be controlled, and the buzzer will sound when the set time has elapsed. Make announcements.

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

(4> Rice cooking control While detecting the temperature with the temperature sensor 2b, the amount of heating is controlled over time based on a program that has been programmed in advance to perform automatic rice cooking.

Next, the relationship between the set time for the simmering operation and the minute setting switch 16 in this embodiment will be explained based on FIG. 8.

For example, if you want to set 37 minutes as the simmering time,
When the minute setting switch 16 is turned on at the same time as the minute setting switch 16 is turned on, the first incrementing operation is performed and the set value becomes one minute.

If you continue to turn on the minute setting switch 16, 0.5 seconds have elapsed, and every further 0.3 seconds, a second increment operation is performed, in order of 5 minutes, then 10 minutes.
It changes as minutes, 15 minutes,..., 30 minutes, 35 minutes.

During this time, the numerical values displayed on the numerical display 20 change sequentially, but the speed of change is every 0.3 seconds, so the operation of the minute setting switch 16 is stopped when the display reaches 35 minutes. Then, it can be stopped sufficiently before the set value increases to 40 minutes.

Thereafter, if the minute setting switch 16 is further operated twice within 0.5 seconds, the first increment operation is performed twice and the set value can be set to 37 minutes.

As described above, in this embodiment, even if the set time for timer operation is set continuously for each unit, by continuing to operate the minute setting switch, the set value can be set to a value greater than the number of units. Since it can be changed at intervals, it is possible to quickly approach the desired set value.

At this time, there is no need to perform any troublesome operations on the minute setting switch; you can simply hold it down.

It doesn't take much time to operate.

In addition, the numbers displayed at this time correspond to the set values and change at a speed that is sufficiently visible, so if you check the displayed numbers before performing an operation, the numbers will remain as they are displayed. A numerical value can be used as a set value.

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

In the above embodiments, a gas stapler was used as an example, but other appliances such as a microwave oven, an open cooker, a heater, a heat insulator, etc. may be used.

Further, although the set numerical value is used for the timer operation, it may also be used as a set temperature for a water heater, various types of Calorie heaters, etc.

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