Abstract

PURPOSE:To make it possible to prevent the deterioration of food even if setting equal to or more than a predetermined time is performed, in machinery using food such as a rice cooker, by outputting a time reservation error signal when the time difference between reservation time and the present time is a predetermined time or more. CONSTITUTION:The reservation time set by a reservation time setting means 4 consisting of a plurality of keys is stored in a reservation time memory part 1. The time difference between the stored reservation time and the present time timed by a timing part 9 is calculated by a reservation error detection part 10 and, if said time difference is a predetermined time or more, a reservation error signal is outputted and the time after a predetermined time from the present time is stored in the memory part is corrected reservation time. An alarm means 11 informs that the reservation time is erroneous to a user on the basis of the reservation error signal and the present time or the reservation time is displayed on a display part 2. Further, the present time and the reservation time stored in the memory part 1 are compared by a time-comparing part 12 and, if both times coincide, a coincidence signal is outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a time setting type timer device for setting a time desired by a user.

Conventional technology Conventional timer devices only compare the current time and the reserved time and output a match signal if the current time matches the reserved time, regardless of how many hours later the reserved time is from the current time. , which performed the operations described above.

Problems to be Solved by the Invention With such conventional timer devices, when the timer is operated for a short period of time in a device that uses food such as a rice cooker, there is no problem if the timer is operated for a short time, but if the timer is operated for a long time. Furthermore, it is not sanitary to leave food in the equipment, especially in the summer when food is easily perishable.

The present invention is intended to solve these problems, and aims to provide a timer device that can prevent food from deteriorating even if a predetermined time or more is set when a reservation time is set. .

Means for Solving the Problems In order to solve the above problems, the present invention calculates the time difference between the reservation time set by the reservation time setting means consisting of a plurality of keys and the current time, and calculates the time difference between the reservation time and the current time. If this is the case, the reservation time error detection unit outputs a signal as a reservation error signal, operates a warning means based on the signal, notifies the user that the reservation time is incorrect, and informs the user that the reservation time is incorrect. The time is stored as the reservation time in the reservation time storage section, and the time comparison section that compares the current time and the reservation time outputs a match signal after a predetermined time.

Effect of the Invention With the above-described configuration, the present invention can notify the user that the reservation time was set incorrectly when the reservation time is set to a time that is longer than the current time by a predetermined time, and the current time can be set as the reservation time. Since the time is set after a predetermined period of time has elapsed, it is possible to prevent food from deteriorating due to being left for a long time.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a block diagram of a timer device according to an embodiment of the present invention, and FIG. 2 is an operation panel diagram of the timer device. In FIG. 1, 1 is a reservation time storage unit;
Remembers the reservation time. 2 is a display section, and this display section 2
As shown in FIG. 2, it is composed of an LCD or an I4D.

Reference numeral 3 designates a display switching key, and in FIG. 2, the display switching key 3 is labeled with "prediction". Then, press this display switching key 3 once to enter the reserved time setting mode, the display section 2 will display the reserved time, and press it again to enter the reserved time setting mode.
The reserved time setting mode is canceled and the current time is displayed on the display unit 2. Thereafter, this process is repeated every time the display switching key 3 is pressed.

4 is a reservation time setting means, and this reservation time setting means 4 is
As shown in Fig. 2, it consists of an hour key 6, a minute key 6, and a memory key 7. By pressing the hour key 5 when setting the reservation time, the hour digit of the reservation time displayed on the display section 2 can be changed. Increase sequentially (from M12:00 to M1:O
O-mu 2:00~Mu M11: 00 →PM12
: 00 to 11:00 PM to 12:00 PM (repeat), set the desired reservation time in the time digit. Also, by pressing the key e, the minute digits of the reservation time are sequentially increased in the same way as the hour key 11 (repeat from oo-o1 to 59-00) to set the reservation time analysis. When the time displayed on the display section 2 reaches the desired reservation time, by pressing the memory key, that time is stored in the reservation time storage section 1 as the reservation time. In this case, hour key 6,
Even if the time is set using the minute key 6, the time will not be stored unless the memory key 7 is pressed.

8 is a start key, and when this start key 8 is pressed, the display section 2 displays the current time, and the reservation time stored in the reservation time storage section 1 and the clock section 9 that measures the current time are displayed. The reservation error detection unit 10 detects the time difference with the time of
As a result of the calculation, if the time difference is more than a predetermined time, a reservation error signal is output and a buzzer or LCD display (
2), the warning means 11 composed of LICD etc. notifies the user, and calculates the time after a predetermined time has elapsed from the current time,
The time is stored in the reservation time storage section 1 as a reservation time, and the timer operation is started. In other words, if the time difference between the reserved time and the current time is less than a predetermined time, the timer operation will continue as is, but if it is greater than or equal to the predetermined time, the timer operation will be performed with the time after the predetermined time elapsed from the current time as the reserved time. It is something.

While the timer is operating, the time comparator 12 compares the current time (the time of the timer 9) and the reserved time, and outputs a match signal when the two match. Further, while the timer is operating, the display on the display section 2 displays the current time, but if the display switching key 3 is pressed at this time, the reserved time is displayed only while the display switching key 3 is pressed. If the reservation time is incorrect when setting the reservation time, the reservation time newly calculated by the reservation error detection unit 1o is displayed.

Reference numeral 13 is a microcomputer 9, which uses a program to store a reservation time storage unit 1. Timing section 9. Reservation error detection unit 109
The time comparison unit 12 is realized.

Effects of the Invention As described above, according to the present invention, when a time more than a predetermined time is set as the reservation time from the current time, it is possible to notify the user that the reservation time was set incorrectly, and also to notify the user that the reservation time has been set incorrectly. Since the time is set after a predetermined period of time has elapsed from the current time, it is possible to prevent food from deteriorating due to being left out for a long time.Also, even if the timer is running and the reservation time is lost, the current time on the display will be set. The reservation time can be confirmed with a simple operation of pressing the display switching key that switches the display of the reservation time.
