Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a timer device for a rice cooker used in general households.

2. Description of the Related Art Conventional timer devices for rice cookers have generally been time setting type analog or digital timers.

That is, the current time is subtracted from the time when rice cooking should be started, and the number of hours after which rice cooking should be started is set using an analog or digital timer. In addition, there are time setting type timers such as audio timers, but when the reserved time is changed, that time is newly stored and the previous reserved time is erased.

Problems that the invention aims to solve With conventional time setting timers, it is cumbersome to calculate how many hours later to start cooking rice, and even though the time for cooking rice is almost fixed every day. However, the time had to be set every day, making it very inconvenient to use. On the other hand, with a time setting timer, you do not have to worry about calculating how many hours later to start cooking rice, but if you change the reserved time, that time will be stored in the new memory until the next change. That time becomes the reserved time, so it is not possible to set a fixed cooking time on weekdays and then cook rice at a different reserved time only on holidays, which is also very inconvenient. there were.

The present invention solves these conventional problems and aims to provide a timer device for a rice cooker with improved operability.

Means for Solving the Problems In order to solve the above problems, the present invention provides a reservation time setting means for changing the rice cooking reservation time, and whether the changed reservation time is to be used temporarily or constantly. The apparatus is equipped with a reserved time designation means for designating a reserved time, a first storage means for storing a temporarily used reserved time, and a second storage means for storing a permanently used reserved time.

Effects According to the above configuration, the reserved time in the second storage means can be called up and used at all times on weekdays, and when the rice cooking time is temporarily changed such as on holidays, the reserved time in the first storage means can be recalled and used. By using the system, there is no need to set a timer every day, and even if the reservation time is temporarily changed, the reservation time that is always used remains stored, making it very easy to use.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. Fig. 1 shows the operation section of the rice cooker in one embodiment of the present invention, where 1 is a reservation call key for calling up the rice cooking reservation time, and 2 is a reservation call key for calling up the reservation time to change the "hour" digit of the reservation time. Hour key, 3 is the minute key to change the digit of 1 minute, 4 is the memory completion key to specify whether to use the changed reservation time temporarily or permanently, 6 is the rice cooking key to start the timer operation , 6 is a display means consisting of a liquid crystal display element that displays the current time and the reserved time, and 7 and 8 are light emitting diodes that each indicate the operating mode of the rice cooker.

5.-1. Next, the operation of the above configuration will be explained. First, if you cook rice every day at 7 p.m., use the reservation call key 1.
Press to call up the reserved time, and press hour key 2 and minute key 3 to set l'-PM7:ooj. After that, when the memory completion key 4 is pressed, the reserved time to be used all the time is specified, and when the rice cooking key 5 is pressed, the timer operation starts, and the display on the liquid crystal display element 7 changes to the current time, and the timer emits light. The diode 7 emits light, and if the reserved time and the current time match, that is, at 7200 p.m., rice cooking will begin. When this rice cooking is started, the rice cooking light emitting diode 8 emits light. Since this reserved time is stored, if the user wants to start the timer operation again to cook rice at 7:00 pm, all he has to do is press the reservation call key 1 and then the rice cooking key 6. If you still want to temporarily change your reservation time due to unexpected guests or holidays,
After pressing the reservation call key 1 and calling up the reservation time that is always used, the reservation time is changed using the hour key 2 and the minute key 3. And memory completion key 46A-.

If the rice cooking key 6 is pressed without pressing , rice cooking will start at the reserved time. However, if you press the reservation call key 1 after that, the reservation time (7:00 PM) that was stored for constant use will be displayed.
0) is called, and by simply pressing the rice cooking key 6, rice cooking can be started at the reserved time (7:00 PM), which is not normally used. Note that when rice cooking is started, the light emitting diode 8 emits light.

In FIG. 2, reference numeral 9 denotes a reservation time setting means, which corresponds to the reservation call key 11 o'clock key 28 minute key 3 described above. Reference numeral 10 denotes a reservation time designation means, which corresponds to the memory completion key 4 described above. 11 is a timer starting means, which is the rice cooking key 5 mentioned above.
corresponds to Reference numeral 12 denotes a first storage means for temporarily storing a reserved time. Reference numeral 13 denotes a second storage means that stores reserved times that are always used. That is, when the time is set by the reservation time setting means 9 and the timer start means 11 is pressed, it is checked whether the reservation time designation means 10 has been pressed, and if it has been pressed, the time is stored in the 21st storage means. 13, and as the keys are pressed, the first memory 7/, -7 is stored in the storage means 12. 14 is a reservation time selection means that determines whether or not the first storage means 12 has been rewritten;
If the data has been rewritten, the first storage means is selected; otherwise, the second storage means is selected. Reference numeral 15 denotes clock means for measuring the current time.

Comparison means 16 compares the current time from the clock means 16 and the reservation time selected by the reservation time selection means.
, if they match, a match signal is output. 17 is the starting means,
Upon receiving a match signal from the comparing means 16, the rice cooker is turned on to start cooking rice. Next, if the reservation call key 1 is pressed to restart the timer operation, the reservation time stored in the second storage means 13 is displayed on the display means 6. At this time, the timer starting means 11 without changing the reserved time.
When is pressed, the reserved time stored in the second storage means 12 becomes the next reserved time and the timer operation is started.

In the above embodiment, the reservation time is the rice cooking start time, but it may also be the rice cooking end time. In this case, comparison means 16
will compare the current time and the reserved time minus rice cooking time.

Advantages of the Invention According to the present invention, once a reserved time for constant use is set, it can be called and confirmed using the reserved call key. After checking, if you want to cook rice at that reserved time, just press the timer start means and you can cook rice at that reserved time. If you want to change the reservation time, you can do so using the hour and minute keys.

After making the change, if you press the timer start means without pressing the reservation time designation means, the changed reservation time will be valid only once, and the next time you press the reservation call key, you will be able to call up the reservation time before the change. . In this way, you can reserve the time you want to always cook rice, and even if you temporarily change the time and want to cook rice, the time you always want to cook rice will not disappear, making it extremely easy to use.
