Description

[Detailed description of the invention] Industrial application field The present invention is a microcomputer (hereinafter referred to as a microcomputer).
This invention relates to a rice cooker equipped with a timer function.

BACKGROUND OF THE INVENTION In recent years, the use of microcomputers in home appliance products has been remarkable, and rice cookers that use microcomputers to perform timer functions are now appearing in place of the conventional analog timers that utilize timer motors.

Hereinafter, the conventional timer-equipped rice cooker mentioned above will be explained with reference to the drawings. Fig. 3 shows a block diagram of the main parts of the timer function and display of a conventional rice cooker with a timer. do. The operating time of the timer can be increased at predetermined time intervals by the operating time setting means 1. 2 is a time-reducing timer means,
The operating time set by the operating time setting means 1 is decreased over time. 3 is a display means for displaying the remaining operating time of the time reduction type timer in predetermined time units.

Problems to be Solved by the Invention However, in such a configuration, only the remaining time of the timer operation is displayed, so the time when rice cooking starts and the time when rice cooking ends are determined based on the current time and the remaining time of the timer operation. Calculations must be made by adding the time and the average time required for cooking rice, which is very cumbersome, and the display time is only calculated in predetermined units of time, resulting in a lack of accuracy. Also, if the current time is not clear, you can only grasp it in terms of relative time, such as how many hours from now.

The present invention has been carefully designed to solve these problems, and provides a rice cooker with a timer that allows you to easily and accurately know the reserved time by selecting and displaying the current time and the reserved time. The purpose is to provide.

Determined Means to Solve the Problems In order to achieve the above object, the rice cooker with a timer of the present invention has a clock means, a timer means, a selection means, and a display means, and when there is a request from the outside. In other cases, the selection means selects the timer means to display the reserved time, and in other cases, the selection means selects the clock means to display the current time.

According to this configuration, when there is an external request to display the reserved time, the selection means selects the timer means and displays the reserved time, and in other cases, the selection means selects the clock means and displays the current time. The time will be displayed.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of a timer-equipped rice cooker according to an embodiment of the present invention, and FIG. 2 shows a front view of the same rice cooker. In FIG. 1, 4 is a clock means;
5 is a timer means that successively compares the reserved time set by the reserved time setting means 6 with the output of the clock means 4; Numeral 7 is a key manual means which inputs information to the reservation time setting means 6 when setting a reservation time, and outputs a request signal when there is an external request to display the reservation time. 8 is a selection means,
When a request signal is received from the key human power means 7, the timer means 5 is selected and the reserved time is output to the display means 3. If there is no request signal, the clock means 4f! : Select and output the current time to the display means 3.

In FIG. 2, numeral 9 denotes a liquid crystal display element (LCD), which is driven by the display means 3. As shown in FIG. 10a.

10b and 1oC are light emitting display elements (LEDs), which are driven by the display means 3 to indicate when the timer is operating, when rice is being cooked, and when it is being kept warm, respectively. 11 The liquid crystal display element 9 and the light emitting display elements 10a, 10b,
10 c. 12 is a group of input keys,
The key is input to the human power means 7.

According to this embodiment, normally the clock means 4 is selected by the selection means 8, and the display means 3 is controlled by the liquid crystal display element 9.
The current time is displayed by driving the input key group 12.
When you press the reservation time request key, key manual means 7
In response to the output, the selection means 8 selects the timer means 5 and the reserved time is displayed on the liquid crystal display element 9, so that the display of the current time and the reserved time can be switched by a simple operation. Since the reservation time is displayed directly, there is no need for complicated calculations and it is accurate.

In the above embodiment, the timer means 6 is set by the reserved time setting means 6 and is configured to successively compare the reserved time and the output of the clock means 4, but the timer means 6 is set by the reserved time setting means 6. The output of the clock means 4 may be successively compared with the time obtained by subtracting the predetermined rice cooking time from the reserved time set by . In this case, the set reservation time can be set as the cooking time.

Effects of the Invention As described above, the present invention includes a clock means, a timer means, a selection means, and a display means, and when there is a request from the outside, the timer means is selected by the selection means. Since the reserved time is displayed and, in other cases, the clock means is selected by the selection means and the current time is displayed, it is possible to easily switch between displaying the current time and the reserved time. , and can know the exact reservation time.

At the same time, it is also possible to accurately know the relative difference between the current time and the reserved time.
