Description

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

2. BACKGROUND ART Conventional rice cooker timer devices generally select and use a reserved time stored in a storage means and a temporarily set reserved time.

Problems to be Solved by the Invention In such rice cookers, the temporarily set reserved time is not stored after rice cooking is finished, and only one reserved time can be called up and used at any time. However, it has been found that many people use two or more different time slots as their regular reservation times, such as morning and evening, or slightly later times on weekday mornings and holiday mornings. In such a case, even though the second or third reserved time is frequently used, it has to be reset each time, which is very troublesome.

An object of the present invention is to provide a timer device for a rice cooker that solves these problems.

Means for Solving the Problems In order to solve the above problems, the timer device of the rice cooker of the present invention includes a plurality of storage means for storing set reservation times, and a storage means for storing the set reservation times. a register for storing a number stored in the register, an arithmetic means for processing the number stored in the register, and a selection means for selecting a specific storage means from among the plurality of storage means n11, the selection means This configuration is such that a specific storage means is first selected based on the output of the calculation means.

Effect According to the above configuration, when the timer operation starts, the number of the storage means can be stored in the register, so when the next timer operation is performed, the first storage means selected by the selection means is the number of the storage means selected by the selection means. The memory means used for the direct Mfr or the next memory means is a memory means that stores the reservation time that matches the purpose of use, so it does not have to be operated frequently. It is.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention, in which 1 is a clock means for measuring the current time, 2 is a reserved time setting means for setting a reserved time, and 3 is a clock means for setting a reserved time. A plurality of storage means constituted by storage means 3a, sb, and 30 for storing, 4 a register for storing the number of the storage means used 1ifT times, and 6 a calculation means for processing the number stored in the register 4. , 6 is a plurality of storage means 3
a selection means for selecting a specific storage means from among them based on the output of the arithmetic means 5, and a selection means 7 which compares the reserved time stored in the storage means selected by the selection means 6 with the output of the clock means 1 and finds that they match. This is a comparison means that outputs a rice cooking start signal at the same time.

FIG. 2 shows a specific circuit configuration of the first embodiment, and in FIG. 2, 1 to 7 correspond to 1 to 7 in FIG. 1. That is, 1 is a clock means for measuring the current time;
2 stores the reservation time set using the hour digit key 1o and the minute digit key 11, and when the completion key 12 is pressed, the first storage means 3a;
A plurality of memories 6 consisting of the second storage means 3b and the N-th storage means 3C Go-7 Reservation time setting means for writing in any storage means in the means 3, 6 corresponds to the number of times the key is manually operated, It is equipped with a selection key 13 for selecting an arbitrary storage means of the storage means 3 and a start key 14 for starting a timer mode. 4 is a register for storing the storage means 30 number selected by the previous selection means 6; 5 is an arithmetic means for processing the number stored in the register 4; 7 is data transmitted from the selection means 6. and the output data of the clock means 1, and outputs a rice cooking start signal when they match; 16 is a display section for displaying the reserved time and the current time by the display drive section 16;
17 is a microcomputer equipped with the registers 1 to 7 above and various means.

Next, the operation of the first embodiment will be explained. FIG. 3 shows the main part of the flowchart under the control of the microcomputer 17. Step 21 is the initial setting of the parameter J.
Set to O. In step 226B7', the input of the selection key 13 is confirmed, and if there is no input, it is confirmed in step 23 that the selection key 13 has been input at least once. In step 24, assign 1 to J and select key 1.
It remembers that 3 was pressed one or more times. Step 25 adds the number of times corresponding to the number of inputs of the selection key 13 to the previous number K of the storage means. In step 26, it is checked whether K exceeds the number N of the plurality of storage means 3. If it exceeds N, in step 27, 2 is assigned to K, and in step 22
Return to Step 28 is to confirm the start of the timer.
Step 2 continues until the timer start key 14 is pressed.
Repeat steps 2-28. In step 29, K and the number of the storage means are made the same, and in step 30, the number K of the storage means is written into the register 4. In step 31, the data in the register 4 is written into the memory M of the calculation means 6. At step 32, the reserved time is read from the storage means indicated by the memo IJM of the calculation means 6. In step 33, timer mode processing is executed, and in step 34, it is confirmed whether the reserved time stored in the storage means indicated by the memory M of the calculating means 6 and the current time of the clock means 1 7A-1 match. If they do not match, return to step 33 and step 33.34
Repeat the loop. When the reserved time and the current time match, the process moves to step 36 and a rice cooking start signal is output.

For example, the number of the plurality of storage means 3 is two, and the first storage means stores the morning reservation times from Monday to Saturday, and the second storage means stores the reservation times for Sunday mornings. In this case, if the reservation time stored in the first storage means is used on Monday, the first storage means selected by the selection means 6 on Saturday will be the first storage means.

Next, a second embodiment of the present invention will be described. The structure and the circuit diagram showing the specific structure of this second embodiment are the same as those of the first embodiment. The operation of this second embodiment will be explained based on the flowchart of FIG. In this FIG. 4, steps 21 to 36 correspond to steps 21 to 36 in FIG.
is equivalent to

In steps 21 to 28, an arbitrary storage means is selected and the timer mode start is confirmed. When the timer start key 14 is pressed, the number of the storage means selected in steps 29 to 31 is written into the memory V of the calculation means 6. At step 36, 1 is added to the number stored in register 4. In step 37, it is confirmed that the number N of the plurality of storage means 3 is not exceeded. If it has been exceeded, step 38
Assign 1 to K. In step 32, the reserved time is read from the storage means indicated by the memo IJM of the calculation means 6.

In step 33, timer mode processing is executed, and in step 34, it is confirmed whether the reserved time stored in the storage means indicated by the memory V of the calculation means 5 and the current time of the clock means 1 match. If they do not match, the process returns to step 33 and the loop of steps 33 to 34 is repeated. When the reserved time and the current time match, the process moves to step 35 and a rice cooking start signal is output.

For example, if the number of storage means 3 is two, and the first storage means stores the morning reservation time and the second storage means stores the evening reservation time, then the morning reservation time is selected. After using the selection means 6, the storage means selected first becomes the second storage means storing the reservation time for the evening. Then, if the reservation time for the night stored in the second storage means is used, the storage means selected first by the selection means 6 becomes the first storage means, and each time the reservation time is used, The reservation times stored in the selected storage means are alternately selected in the morning and in the evening.

Effects of the Invention As described above, according to the present invention, among the plurality of storage means,
For example, when the reserved time stored in the Kth storage means is executed, the reserved time number is written to the register and processed, so when selecting the next reserved time, the number used last time will be used. The reservation time or the next reservation time can be selected at one time, and as a result, operability can be significantly improved.
