DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer device for a cooking appliance having a built-in clock function and capable of performing a timer operation by a timer setting means for setting an end time of cooking.

[0002]

2. Description of the Related Art In general, a time adjustment method for a clock or the like having a built-in timer device is performed by sending or returning a time, and an hour digit and a minute digit are separated, and these are separated by separate operation means. Although there are two types of cooking devices known in the art, a digital display type display means is used for a cooker having a limited time display unit in order to improve the visibility to the user. Those that have become mainstream. However, particularly in the case of a cooker used daily in ordinary households, a cooker provided with a 24-hour clock display means capable of setting a timer time of 12 hours or more is convenient and convenient. To quickly set the time, press and hold the operation means to fast-forward the time.Therefore, the time and minute digits are set faster than the method of adjusting the time by sending or returning the time. The method of adjusting the time by separating and sending these by separate operation means is superior in terms of ease of use. In the former method of simply sending or returning the time without separating the hour and minute digits, for example, 12:00 am to 12 pm
If you want to change the time, you need to send or return 720 minutes (12 hours), it takes time to adjust the time, and if you try to send the time in a short time with the fast forward function, the fast forward speed is too fast This is also caused by the fact that the display of the minute digits becomes invisible. In this case, even if the fast-forward speed is set to about 10 minutes / 1 second so that at least the tens digit can be seen, it takes 72 seconds to change the time by 12 hours, and it takes time to adjust. The disadvantage of too much cannot be removed.

[0003]

In the case of a cooker adopting the above-mentioned method of adjusting the time by separating the hour and minute digits, generally, the space on the operation unit is limited and the operation unit is complicated. From the viewpoint of minimizing the feeling, only the hour or minute digits can be fed in order to reduce the number of operation means for setting the time that is not frequently used. However, in such a configuration, when the time to be set during the adjustment is passed, the time must be sent once again, and in particular, when the hour digit is sent in units of one hour in 24 hours, the time digit is set in units of 24 hours. While it goes around once, the minute digit is 60 when sending 60 minutes in 1 minute units.
When the same rapid traverse speed is set,
There is a disadvantage that the adjustment time of the minute digit takes longer than the adjustment time of the hour digit. Also, in this case, it is conceivable that the minute-digit fast-forward speed is faster than the hour-digit fast-forward speed, but a counter for fast-forward must be provided separately for the hour and minute digits, which complicates the control configuration. In addition to the above, the difference in the fast-forward speed between the two causes the user to feel visually uncomfortable and to have an impression that it is difficult to use.

[0004] Therefore, an object of the present invention is to provide a cooker that can quickly adjust the time without complicating the control configuration and without giving a sense of visual discomfort.

[0005]

According to a first aspect of the present invention, there is provided a cooker comprising: a time digit display section for displaying 24 hours in units of one hour;
A minute digit display unit for displaying 0 minutes in units of one minute, an hour digit operation unit for sending a time displayed on the hour digit display unit, and a minute digit operation unit for sending a time displayed on the minute digit display unit. An hour digit feeder for transmitting the time of the hour digit display unit in units of one hour each time the hour digit operation unit is operated, and a time of the minute digit display unit each time the minute digit operation unit is operated. A minute digit feed means for sending in one minute units, and a time digit for fast-forwarding the time of the hour digit display portion by one hour in 24 hours at a speed of 3 seconds or more and 12 seconds or less by continuously operating the hour digit operation means. Fast-forwarding means, minute-digit fast-forwarding means for fast-forwarding the time of the minute-digit display section at the same speed as the hour-digit fast-forwarding means in units of two minutes by continuously operating the minute-digit operating means, The time displayed on the hour-digit display and the minute-digit display by operating the minute-digit operating means Current time setting means to set as time, timer time setting means to set the end time of cooking, according to the time of the current time set by the current time setting means, according to the time set by the timer time setting means Cooking start means for starting cooking so that the cooking is completed.

Further, in the cooking device according to the present invention, the cooking end time set by the timer time setting means is fast-forwarded at the same speed as the hour digit fast-forwarding means in units of 10 minutes, and the time is 60 minutes. A timer time minute digit fast-forward means for fast-forwarding at a speed higher than the digit fast-forward means is provided.

[0007]

According to the above configuration, when the current time is set, the speed of fast-forwarding the time on the hour-digit display unit matches the speed of fast-forwarding the time on the minute-digit display unit. The time that the time of the part makes one revolution and the time that the time of the minute digit display part makes one cycle are almost the same by fast-forwarding the minute digit display part in units of two minutes. There is no visual discomfort between the two when adjusting the distance.

Next, a block diagram of each function at the time of time setting shown in FIG. 5 will be described. Reference numeral 60 denotes a display time of the hour digit display portion 22 and the minute digit display portion 23 constituting the LCD display device 21; Time adjustment means individually adjusted by operating the 28 and minute switches 29. This time adjustment means 60
Is a means for transmitting the time displayed on the hour-digit display section 22. Each time the hour switch 28 is pressed, an hour-digit feed means 61 for transmitting the time of the hour-digit display section 22 in one-hour units; When 28 is pressed for more than one second, hour digit fast-forwarding means 62 for fast-forwarding the time of the hour-digit display unit 22 by one hour in 0.25 seconds, ie, 24 hours in 6 seconds. ing.
The time adjusting means 60 is a means for transmitting the time displayed on the minute digit display section 23. In the current time adjustment mode, the time of the minute digit display section 23 is incremented by one each time the minute switch 29 is pressed. The current time / minute digit feeding means 63, which is a minute / digit feeding means for sending in minute units, and the timer time / minute which sends the time of the minute digit display section 23 in 10 minute units each time the minute switch 29 is pressed in the timer time adjustment mode. When the minute switch 29 is pressed for more than one second in the current time adjustment mode with the digit feed means 64, the time on the minute digit display section 23 is set to two minutes in units of two minutes.
When the current time / minute digit fast-forward means 65 for fast-forwarding 25 seconds, that is, 60 minutes at a speed of 7.5 seconds, and when the minute switch 29 is kept pressed for 1 second in the timer time adjustment mode,

Reference numeral 67 denotes fast-forward counter means for setting the fast-forward speed of the time displayed on the hour-digit display section 22 and the minute-digit display section 23. In this embodiment, the common fast-forward counter means 67 uses the hour-digit fast-forward means 62 and the current time. It should be noted that the fast-forward speed of the minute digit fast-forward means 65 and the timer time minute-digit fast-forward means 66 are set to 0.25 seconds per one unit. In this case, it is preferable that the time of the hour digit display section 22 be fast-forwarded by the fast-forward counter means 67 at a speed of 3 seconds or more and 12 seconds or less in 24 hours in units of one hour. This is because, although there are some individual differences from the experimental results, in the case of the hour-digit display unit 22, when fast-forwarding 24 hours around one cycle in less than 3 seconds, the time is sent too fast and the numeral shape can be recognized. In addition, if the time is fast-forwarded for 24 hours or more for 12 seconds or more, the time advance is too slow and the adjustment takes time. Also, in the timer time adjustment mode, the timer time minute digit feed means 64 and the timer time minute digit fast forward means
According to 66, the time of the minute-digit display section 23 can be sent in units of 10 minutes. This is because when the daily timer is used, if the timer time is set too fine, it is easy to get lost when using the timer. Since the operation is performed relatively frequently, unlike the time, it is determined from the viewpoint of setting as quickly as possible.

Reference numeral 68 denotes a time in the current time adjustment mode.
This is current time setting means for setting the time displayed on the hour digit display section 22 and the minute digit display section 23 by operating the hour switch 28 and the minute switch 29 as the current time. When there is an operation input from the clock switch 27 in the off state, the current time setting means 68 switches the clock adjusting means 60 to a current time adjustment mode in which the current time can be adjusted, and displays the hour digit display section 22 and the minute digit display. It also has a function of blinking the unit 23. The time-shifting means 61, the hour-digit fast-forwarding means 62, the current time-minute digit-shifting means 63 and the current time-minute digit-fast-forwarding means 65 until the next clock switch 27 is operated on the time adjusting means 60. Enables adjustment of the current time. Further, when the clock switch 27 is operated in the current time adjustment mode, the time displayed on the hour digit display section 22 and the minute digit display section 23 at that time is set as the current time.

Reference numeral 69 designates the time displayed on the hour-digit display section 22 and the minute-digit display section 23 by operating the hour switch 28 and the minute switch 29 in the timer time adjustment mode as a timer time which is the end time of cooking. Timer time setting means. This timer time setting means 69, when there is an operation input from the timer rice cooker switch 30 in the off state,
It also has a function of switching the clock adjustment means 60 to a timer time adjustment mode in which the timer time can be adjusted, and displaying the timer mode display section 35. Then, until the next operation input of the timer rice cooker switch 30 is input to the time adjusting means 60, the hour digit feed means 61, the hour digit fast-forward means 62, the timer time / minute digit feed means 64, and the timer time / minute digit fast-forward means 66.
Allows the timer time to be adjusted. When the clock switch 27 is operated in the timer time adjustment mode, the time displayed on the hour digit display section 22 and the minute digit display section 23 at that time is set as the timer time.

Numeral 70 is a cooking start means for starting the cooking so as to end the cooking at the timer time set by the timer time setting means 69 in accordance with the measurement of the current time set by the current time setting means 68. This cooking start means 70, when the current time reaches a predetermined time before the timer time,
It instructs the rice cooking control means 71 for controlling the cut-off of the rice cooking heating means 50 and the warming / heating means 52 to start the rice cooking operation.

In this embodiment, the same time digit display unit 22 and minute digit display unit 23 are used to display the current time and the timer time as the cooking end time. May be displayed on the hour digit display section 22 and the minute digit display section. Further, the hour switch 28 and the minute switch 29 may be provided separately for the current time adjustment and for the timer time adjustment. However, as in the present embodiment, if the adjustment of the current time and the timer time is performed by the common hour-digit display unit 22 and minute-digit display unit 23 and the common hour switch 28 and minute switch 29, the operation panel 16 Easy to use without complication. Further, in the present embodiment, the time display unit 22 of the 24-hour clock is used in which the display form of morning or afternoon and the numerical form of 1 to 12 are combined.
The time display unit may be a time display unit using only a numerical form capable of displaying a time.

In the above configuration, when the clock switch 27 is pressed while the rice cooking operation is not performed, the current time setting means 68 switches the time adjusting means 60 to a current time adjustment mode in which the current time can be adjusted, The hour digit display section 22 and the minute digit display section 23 are blinked. In this state, the hour switch
Each time 28 is pressed once, the time displayed on the hour digit display section 22 is changed by the hour digit feed means 61 from 12 am → 1 am →→ 11 am → 12 pm → 1 pm →→ 11 pm → 12 am In the order of 1 hour. Each time the minute switch 28 is pressed once, the time displayed on the minute digit display section 23 is changed by the current time / minute digit feeding means 63 from 00 → 01 → 02 →.
The data is sent in units of one minute in the order of 59 → 00. Time adjustment means
60 reads whether or not the hour switch 28 and the minute switch 29 are depressed every 62.5 msec based on the ON / OFF signals from the hour switch 28 and the minute switch 29. When it is detected that the ON signal is output, the time displayed on the hour digit display section 22 is changed by the hour digit fast-forwarding means 62 in place of the hour digit feeding means 61 in the same order as the time sent by the hour digit feeding means 61. Fast forward every hour. When detecting that an ON signal is output from the minute switch 29 for one second or more, the current time / minute digit shifting means 63 is detected.
Instead of this, the current time minute digit fast-forward means 65 fast-forwards the time displayed on the minute digit display section 23 in units of two minutes. At this time, if the time displayed on the minute-digit display section 23 is an odd number, the current time minute-digit fast-forward means 65 sets 01 → 03 → 0.
Fast-forwarding is performed for each odd-numbered unit in the order of 5 →... → 57 → 59 → 01. If the time displayed on the minute-digit display unit 23 is an even number, 00 → 02 → 04 →. → Fast-forward is performed for each even-numbered unit in the order of 00. Then, after the operation of the hour switch 28 and the minute switch 29 is completed, when the clock switch 27 is pressed again, the time blinking on the hour digit display section 22 and the minute digit display section 23 at this time is set as the current time. Is set.

In the current time adjustment mode, when the hour switch 28 is pressed for more than one second, the time of the hour digit display section 22 is set to one.
While one hour can be fast-forwarded for 0.25 seconds in a time unit, ie, 24 hours for one round at a speed of 6 seconds, the minute switch 29
By pressing and holding for more than one second, the time on the minute-digit display section 23 can be fast-forwarded in two-minute increments at 0.25 seconds for two minutes, that is, 7.5 minutes for one round of 60 minutes. That is, the time feed speed of the hour-digit display unit 22 and the minute-digit display unit 23 at the time of fast-forward is 0.25 seconds per one unit, and in this regard, a common fast-forward counter 67 can be used. . Moreover,
At the time of fast-forward, the time of the minute-digit display section 23 is displayed in units of two minutes. Thus, the display time of the hour-digit display section 22 goes around in 24 units, whereas the display time of the minute-digit display section 23 goes in 30 units. The time required for the time of the hour digit display section 22 to make one revolution (7.5 seconds / 24 hours) and the time required for the time of the minute digit display section 22 to make one revolution (6 seconds / 60 minutes) The difference is small.
Therefore, the sense of inconsistency in use when adjusting the hour and minute digits is extremely small, and the usability is improved.

On the other hand, when the timer rice cooker switch 30 is pressed in the off state, the timer time setting means 69 switches the time adjusting means 61 to the timer time adjusting mode in which the timer time can be adjusted, and the LCD display device 21 displays the timer mode. The display unit 35 is displayed. Then, on the hour digit display section 22 and the minute digit display section 23, the timer time stored in the storage device 44 of the microcomputer 41 is displayed. In this state, each time the hour switch 28 is pressed once, the time displayed on the hour digit display section 22 is incremented by one by the hour digit feed means 61, as in the current time adjustment mode.
When the switch 28 is pressed for more than one second at this time, the time displayed on the hour-digit display section 22 is changed by the hour-digit fast-forward means 62 in one-hour increments of one hour at a rate of 0.25 seconds. Fast forward. Also, every time the minute switch 29 is pressed,
The time displayed on the minute-digit display section 23 is set to 00 → 10 → 20 → 30 → 40 → 50 by the timer time / minute digit feeding means 64.
When the minute switch 29 is pressed for one second or longer while being sent in the order of 00 in the order of 00 and the minute switch 29 is kept pressed for one second or more, the time displayed on the minute digit display section 23 is set to 10 by the timer time minute fast forward means 66.
It is fast-forwarded at a speed of 0.25 seconds for 10 minutes in minutes. After the operation of the hour switch 28 and the minute switch 29 is completed, when the timer rice cooker switch 30 is pressed again,
At this time, the time displayed on the hour digit display section 22 and the minute digit display section 23 is set and stored in the storage device 44 of the microcomputer 41 as a timer time which is a cooking start time. At this time, L
In the ED display device 25, the LED corresponding to the timer is turned on to start the timer operation. During the timer operation, the timer time, the time until cooking or the current time is displayed on the LCD display device 21, If the current time reaches 55 minutes before the set timer time, LE
The LED corresponding to the rice cooking on the D display device 25 is turned on, and the cooking start means 70 instructs the heating control means 71 to start the rice cooking operation. The rice cooking start time varies depending on the time required for rice cooking, but in this case, it depends on conditions such as a product and a rice cooking menu. The rice cooking is started, and when the timer time is reached, the rice cooking operation is terminated, and the buzzer device 56 notifies. Thereafter, the LED corresponding to the heat retention of the LED display device 25 is turned on to perform the heat retention heating.

In the timer time setting mode, when the minute switch 29 is pressed for more than one second, the time of the minute digit display section 23 is set to 10 minutes in increments of 10 minutes for 0.25 seconds, that is, one round 60.
The minute can be fast-forwarded at a speed of 1.5 seconds. In this case, it is somewhat difficult to recognize the tens place of the minute digit display section 23, but since the unit is a unit of 10 minutes, it is possible to perform six rounds without performing fast-forward.
It is only necessary to press the minute switch 29 six times to send 0 minutes, and the minute digit of the timer time can be adjusted in a short time.

As described above, the rice cooker as the cooker according to the above-described embodiment corresponds to claim 1, wherein the hour digit display section 22 for displaying 24 hours in units of one hour, and displaying 60 minutes in units of one minute.

By continuing to operate the hour switch 28, the time of the hour digit display section 22 is set to 2 in one-hour units.
Time digit fast-forward means 62 for fast-forwarding 4 hours at a speed of 3 seconds or more and 12 seconds or less, and by continuing to operate minute switch 29, the time of minute-digit display section 23 is set to the same speed as hour-digit fast-forward means 62 in units of 2 minutes. Current time minute digit fast forward means 65 for fast-forwarding, current time setting means 68 for setting the time displayed on the hour digit display section 22 and minute digit display section 23 by operating the hour switch 28 and minute switch 29 as the current time, A timer time setting means 69 for setting an end time of cooking; and a timer time setting means in accordance with the counting of the current time set by the current time setting means 68.
And a cooking start means 70 for starting cooking so as to end cooking at the time set in 69. Therefore, in the current time adjustment mode, the time of the hour digit display section 22 goes around once in 3 seconds to 12 seconds, which is practically convenient during fast-forwarding, and the time displayed on the hour digit display section 22 and the minute digit display section. The fast-forward speed coincides with the time displayed on 23, and the time during which the time of the hour-digit display unit 22 completes a round and the time during which the time of the minute-digit display unit 22 completes a round is indicated by two minutes.
By fast-forwarding by the minute, it will be almost the same,
There is no visual discomfort between the case where the hour digit is adjusted and the case where the minute digit is adjusted, and the usability in operation can be significantly improved. In addition, this can shorten the working time not only in the case of the user but also in the case of shipping after setting the current time at the factory. Moreover, since the fast-forward speeds of the times displayed on the hour-digit display unit 22 and the minute-digit display unit 23 match, the fast-forward operation can be realized by one common fast-forward counter 67, and the control configuration is simplified. Can be achieved.

The fast forward operation is common to the hour digit fast forward means 62 and the current time minute minute fast forward means 65.
The number of fast-forward counters 67 can be realized, and the control configuration can be further simplified.

In the embodiment, the time displayed on the minute-digit display section 23 is fast-forwarded in two-minute units and two minutes is performed in 0.25 seconds. In this case, the display of the tens place of the minute digits display section 23 changes every 1.25 seconds which can be sufficiently recognized. Can be combined. Also, if the time is fast-forwarded in units of 2 minutes, the display of the ones digit cannot be recognized. (In the experiment, if the change of the display is less than 0.5 seconds, it is difficult to see the number form, and the change of the display is 0.5%. Even in the case of seconds to less than 1 second, although the form of the number is visible, it is difficult to recognize it as a number.) It can be used without discomfort.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. In the embodiment, the rice cooker has been described as an example of the cooker, but the present invention can be similarly applied to other various cookers.
