Abstract

PURPOSE:To make it possible to set a time and designate a time, by calling and using always a reservation time of the second storage means and using a reservation time of the first storage means only when it is rewritten. CONSTITUTION:When the signal from a timer start means 18 (corresponding to a start switch) is inputted to a reservation time slecting means 16, this means 16 sends a selected time to a next comparing means 19. The comparing means 19 compares the present time from a clock means 20 with the reservation time and sends a coincidence signal to a next start means 21, and a switch of a rice cooker is turned on. When rice cooking is started, the reservation time selecting means 16 selects the next reservation time and displays it on a display means 17. At this time, if the reservation time is not changed and the start switch is depressed, the second stored time is used as the next reservation time to start a timer.

Description

DETAILED DESCRIPTION OF THE INVENTION Page 2 Industrial Application Field The present invention relates to a device, such as a rice cooker, which is convenient to use with a constant timer set at all times.

This invention relates to timer devices used in alarm clocks, video tape recorders, and the like.

Conventional configurations and their problems Taking conventional rice cookers as an example, they are generally time-setting type with an analog or digital timer. Then, use an analog or digital timer to set how many hours you want the rice to start cooking. However, with this configuration, it is a hassle to calculate how many hours later it will be, and furthermore, when setting a timer, you have to set the time every day even though the time to cook rice is almost fixed. However, it is extremely difficult to use. There are still some video tape recorders that can store the time using a time setting type timer, but while there is no need to worry about calculating how many hours later it will be, if the time is changed, the time will be changed to the new time. The time is memorized and remains the timer time until the next change is made, so it is not possible to set the timer time to be used all the time and record only a series program, making it inconvenient to use. It was something.

OBJECTS OF THE INVENTION The present invention provides a timer device that solves the problems of the prior art, and improves the operability of the device.

a reserved time setting means for temporarily using the reserved time set by the reserved time setting means; a reserved time specifying means for specifying whether the reserved time set by the reserved time setting means is to be used constantly; a first storage means; a second storage means for storing a reserved time that is always used;
Only when the reserved time in the storage means of
a reserved time selection means for selecting a stored time of the first time and a second stored time for other times; a display means for displaying the selected reserved time; a clock means for measuring the current time; The current time of the timer is compared with the selected reserved time, and the comparison means outputs a matching signal, and the start means starts the operation based on this output. The reserved time in the first storage means is always recalled and used, and the reserved time in the first storage means is used only when it is rewritten.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. The figure shows an example of a rice cooker, in which 1 is the rice cooker main body, 2 is a rice cooking lid, 3 is a handle of the rice cooking lid, and 4 is an operating section provided on the front of the rice cooker main body 1. The configuration of the operating section 4 is shown below.

5 is a key switch for setting the "hour" digit of the reservation time, 6
The key switch 17 for setting the minute digit is an LCD display device for displaying the reservation time, 8° and 9 are light emitting diodes that indicate the operating mode of the rice cooker, 1o is a start switch for starting the timer operation, and 11 is a This is a switch 5 to specify whether the reserved time to be set is for permanent use or for temporary use.

Next, the operation will be briefly explained based on FIG.

First, if the time to cook rice every day is 7 p.m., press the designation switch 11 and press the 1 o'clock and minute key switches 5 and 6 to set rPM7:00J. Thereafter, when the start switch 1o is pressed, the timer operation is started and the light emitting diode 8 of the timer emits light, and if the reserved time and the current time match, that is, at 7:00 p.m., rice cooking starts. This reserved time is stored, and if you want to start the timer operation again and start cooking rice at 7:00 p.m., all you need to do is press the start switch 10. Also, if you want to temporarily change the reservation time due to unexpected customers or holidays, do not press the designated switch 11, but press the key switch 5.
, 6 to change the reservation time. Then, as described above, when the start switch 1o is pressed, rice cooking starts at the reserved time. However, after that, the reserved time (7:00 PM) stored in the display device 7 for constant use
is displayed and that time is set as the next reserved time on page 6, and rice cooking can be started at that time simply by pressing the start switch 10. In addition,
When rice cooking starts, the light emitting diode 9 emits light.

In FIG. 3, 12 is a reserved time setting means, which corresponds to the key switches 5 and 6 described above. Reference numeral 13 denotes a reservation time designation means, which corresponds to the designation switch 11. That is, when the reservation time setting means 12 sets the time, it is checked whether the designated switch 11 is pressed at the same time, and if it is pressed, the time is stored in the second storage means 14, and if it is not pressed, the time is stored in the second storage means 14. It is stored in the first storage means 15. All of these processes are performed within the microcomputer, and the time storage location is allocated within the RAM.

The reservation time selection means 16 first determines whether or not the first memory time has been rewritten, and if it has been rewritten, selects the first memory time, and if not, selects the second memory time, and selects the second memory time. The reserved time is displayed by the display means 17 (corresponding to the display device 7).

Here, when there is a signal from the timer start means 18 (corresponding to the start switch 7, start switch 10), the reservation time selection means 1
6 sends the selected time to the next comparing means 19. The comparison means 19 compares the current time from the clock means 2o with the aforementioned selected time (reserved time), and if they match, sends a match signal to the next start means 21. The starting means 21 receives this signal and
Turn on the rice cooker and start cooking. When rice cooking starts, the reserved time selection means 16 starts operating again, selects the next reserved time, and displays it on the display means 17. (if there is no signal), the second storage time will be automatically selected. Therefore, if the timer starting means, that is, the start switch 10 is pressed without changing the reserved time, the second stored time becomes the next reserved time and the timer operation is started. Unless there is a change in the reservation time,
repeated.

Note that the operation of the reserved time selection means 16 may be restarted at the end of rice cooking.

Next, in step 22, the processing in the microcomputer will be explained based on FIG.
Determine if is pressed. If there is key power, it is determined in step 23 whether or not that time is a time to be used regularly by listening to the state of the designated switch 11. If the time is always used, it is stored in RAM2, otherwise it is stored in RAM1. In the subsequent step, that time M is displayed.

In step 24, the input of the start switch is heard and determined. If there is input, the current time is read. If not, the process returns to step 22. When the current time N is read, the displayed time M and the current time N are compared and determined in step 26, and if they match, rice cooking is started. If not, wait until there is a match.

After that, the process returns to step 22. Note that if there is no change in the reserved time in step 22, the time in RAM 2 is displayed and the process moves to the following step.

Although the above embodiment has been explained using a rice cooker as an example, the timer of the present invention can be applied to devices such as alarm clocks, video tape recorders, etc. that are convenient to use with constant time settings. It is clear that the device can be used.

Effects of the Invention As is clear from the above-mentioned embodiments, the timer device of the device of the present invention is a time setting type and can specify the time, and once the reserved time for constant use is set, the timer device can be used with one-touch operation. can work. Moreover, even if the reserved time is changed, the next reserved time is automatically set to the time for regular use, so the operability of the device is extremely improved.
