Abstract

PURPOSE:To enhance the manipulatability of a timer upon setting a timer operating time by providing such an arrangement that a hour increase for the operating time is made by solely pushing a hour key while a minute increase is made by solely pushing a minute key, but a decrease in the operating time is made by simultaneously pushing both hour and minute keys. CONSTITUTION:When the hours of an operating time is increased, a hour key is solely pushed, while when the minutes of the operating time is increased, a minute key is solely pushed. Further, when the set operating time is decreased, the hour and minute keys are simultaneously pushed so as to set a predetermined operating time. With this arrangement, a long operating time can be simply set. Thereby it is possible to provide a timer device for an electric cooker, which is excellent in the manipulatability.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a timer device for an electric cooker.

BACKGROUND OF THE INVENTION As shown in FIG. 4, this type of timer device has an up key 1 and a down key 2 for setting the timer operating time on the operating section, and an LC that is a display means for displaying the timer operating time 3.
D4, and is configured such that when the up key 1 is pressed, the operating time value increases, and when the down key 2 is pressed, the operating time value is decreased. and,
When the operating time set in this timer has elapsed, the electric cooker starts operating.

Problems to be Solved by the Invention However, in the above conventional timer device, each key 1,
Since the operation time can be increased or decreased by pressing 2, when setting the operation time to a long time, it is necessary to keep pressing the up key 1 for a long time, which is a problem in that it is cumbersome and inconvenient to use.

The present invention solves these conventional problems,
The object of the present invention is to provide an excellent timer device for an electric cooker that allows easy setting of operating time and is easy to use.

Means for Solving the Problems In order to achieve the above object, the present invention has an hour key and a minute key, in which pressing the hour key alone increases the hour digit of the operating time, and pressing the minute key alone increases the operating time. The minute digits are increased, and the operating time can be decreased by pressing the hour and minute keys simultaneously.

Therefore, according to the present invention, when increasing the hour digit of the operating time, press the hour key alone, when increasing the minute digit of the operating time, press the minute key independently, and when the set operating time When decreasing the time, the required operating time can be set by pressing the hour key and the minute key at the same time, and even a long operating time can be easily set.

Embodiment FIGS. 1 and 2 show an embodiment of the present invention, which is applied to a household electronic jar rice cooker. In Fig. 1, 11 is a reservation key to start setting the operating time, 12 is a time key to set the hour digit of the operating time, 13 is a minute key to set the minute digit of the operating time, and 14 is a rice cooking key 15 to start the timer operation. An LCD is a display means for displaying the current time and the operating time set by each key 12, 13.

In FIG. 2, 16 is an input means having an hour key 129, a minute key 13, etc.; 17 is an input means for increasing the hour digit of the operating time by pressing the hour key 12 alone; and increasing the minute digit of the operating time by pressing the minute key 13 alone. This is a microcomputer control means that increases the minute digit of the operating time and decreases the minute digit of the operating time by pressing the hour key 12 and minute key 13 at the same time, and displays these on the LCD 15.

Next, the operation of the above embodiment will be explained. To set the operating time for the electronic jar rice cooker to start cooking rice, first press the reservation key 11 to switch the LCD 15 to the operating time setting mode.

The process will be explained below with reference to the flowchart shown in FIG.

In step 18, the mode is switched to the operating time setting mode by pressing the reservation key 11, and in the next step it is determined whether or not to set the operating time. If the operating time is not set, the process moves to other processing. When setting the operating time, in the next step 2o, it is determined whether there is an input by pressing the hour key 12 alone, and if there is an input by pressing the hour key 12 alone, the hour digit memory of the operating time is stored in the next step 21. The value is incremented by 1 and the process moves to the next step 22. If there is no single input using the hour key 12, the process moves from step 2o to step 22. In step 22, it is determined whether or not there is an input by pressing the minute key 13 alone, and if there is an input, the minute digit memory of the operating time is incremented by 1 in the next step 23, and the process moves to the next step 24. If there is no single input using the minute key 13, the process moves from step 22 to step 24. In step 24, it is determined whether or not there is an input by pressing the hour key 12 and minute key 13 at the same time. If there is simultaneous input, the minute digit memory is moved down by 1 in the next step 25, and the process moves to step 26.

If there is no simultaneous input, steps 24 to 26
Move to. In step 26, the set operating time is displayed on the LCD.
Check on 15. In step 27, it is determined whether or not there is an input using the rice cooking key 14. If there is an input using the rice cooking key 14, the process moves to step 28, and this timer operation is started. If there is no input from the rice cooking key 14, proceed to step 18.
Return to , and repeat the same operation.

2, according to the above embodiment, when increasing the hour digit of the timer operating time, press the hour key 12 alone; when increasing the minute digit of the timer operating time, press the minute key 13 alone; Furthermore, when decreasing the minute digit of the timer operating time, the required operating time can be set by pressing the hour key 12 and the minute key 13 at the same time, and the advantage is that it is especially easy to set a long operating time. has.

In the above embodiment, the minute digit is decremented by 1 by pressing the hour key and the minute key at the same time, but the hour digit may be decremented by 1 instead. In this case, it has the effect of making it easier to correct errors in time setting.

Effects of the Invention As is clear from the above embodiments, the present invention allows inputting an increase in the hour digit of the operating time by pressing the hour key alone, inputting an increase in the minute digit by pressing the minute key alone, and inputting a decrease in the operating time. The operating time is set by pressing the hour key and minute key at the same time, making it easy to set a long operating time or change the operating time, improving operability in setting the timer operating time. It has the advantage of being able to achieve
