Abstract

PURPOSE:To reduce the operating labor of the user of a rice cooker and facilitate rice cooking work by composing a reservation timer time in a memory so that the operation frequency of a timer start switch may be made lower as the using frequency of the timer time is higher. CONSTITUTION:When a timer start switch 7 is operated (pushed) one time, an 8-hour timer lamp 14 is lit, and a timer 2 is started, and a passage time T is counted. At the same time, the passage time T and an 8-hour reservation timer time T2 stored in a memory 3 are compared with each other by a comparator circuit 5, and when T>=T2, a rice cooking lamp 16 is lit, and by signal from the comparator circuit 5, a relay controlling circuit 4 is worked, and a transistor 8 is electrified, a relay circuit 9 is worked, and a contact 10 is closed, and power is fed to a heater 12 from a power source 11, thus, rice cooking is started. It is 8 hours later than the time when the timer start switch 7 is turned ON. When the timer start switch 7 is operated twice, then in a same manner, 10 hours later, the rice cooking is started, and when the switch 7 is operated three times, 6 hours later, the rice cooking is started.

[Prior Art] Rice cookers that heat and cook rice using electricity are now popular throughout the country and have become essential appliances in the kitchens of every household. Some rice cookers are equipped with a timer and are configured to set a reserved time using the timer so that the rice is cooked in time for the meal even if the user is not present.

A rice cooker equipped with such a timer is equipped with a rice cooking switch and a reservation timer time setting switch.If you want to cook rice immediately, turn on the rice cooking switch and the rice cooker's heater will immediately turn on and start cooking. is started. If you want to cook rice after a predetermined time, first set the elapsed time until the start of rice cooking using the reservation timer time setting switch, then turn on the rice cooking switch.The timer will operate and the heater will turn on after the predetermined time and start cooking.

Depending on these usage conditions, some rice cookers have a timer start switch that can be turned on without setting a reserved timer time.
Some devices are configured so that simply by setting N, the heater turns on and starts cooking rice after a preset reservation timer time has elapsed.

Among the rice cookers that start cooking after the reserved timer time, there are some that set a timer each time they cook rice and start cooking after the reserved timer time, and some that set the timer every time they cook rice and start cooking after the reserved timer time. Afterwards, the heater is turned on.
There are two types: one that starts cooking rice next to the other.

[Problem to be solved by the invention] By the way, among the above two types of rice cookers, the former uses a timer to set a reserved time and then turns on the rice cooking switch, so two operations are required each time rice is cooked, making the operation cumbersome. There is a problem with this point.

[Means for Solving the Problems] In order to achieve the above object, the rice cooker according to the present invention includes a memory in the control device to store a plurality of frequently used reservation timer times, and to set the timer to start. The reserved timer time in the memory that operates in response to switch operations is configured such that the more frequently used, the fewer times the timer start switch is operated.

[Function] Since the rice cooking control program of the rice cooker is configured as described above, for example, one operation of the timer start switch activates the most frequently used reserved timer time, and two operations activates the most frequently used reserved timer time. It can be configured such that the number of times the switch is operated is reduced in accordance with the frequency of use of the reserved timer time, such as when the timer start switch operates at a higher time. As a result, the operation of the rice cooker is largely complicated.

Next, the operation will be explained. In FIG. 1, when the rice cooking switch 6 is turned on, the rice cooking lamp 16 lights up, the relay control circuit 4 operates, the transistor 8 becomes conductive, the contact 10 closes, and power is supplied from the power source 11 to the heater 12. The rice will start cooking. Subsequently, when the timer start switch 7 is operated (suppressed) once, the 8-hour timer lamp 14 lights up, the timer 2 starts, and the elapsed time T is counted. At the same time, the comparison circuit 5 compares the elapsed time T and the 8-hour reserved timer time T2 stored in the memory 3, and if T≧T2, the rice cooking lamp 16 lights up, and a signal from the comparison circuit 5 causes the relay control circuit 4 to is activated, transistor 8 is made conductive, relay circuit 9 is operated, contact 10 is closed, power is supplied from power source 11 to heater 12, and rice cooking is started. Turn on timer start switch 7
It's been 8 hours since I did it.

Note that FIG. 3 shows a flowchart of the above operation. As shown in the figure, it is determined whether the rice cooking switch 6 is 0N10FF (81), and if it is ON, rice cooking is started (S2
). If it is OFF, it is determined whether or not the timer start switch 7 has been operated (S3), and if it has been operated, the timer 2 is started and the elapsed time T is counted (S4). Next, it is determined whether or not there is a second operation of the timer start switch 7 (S5), and if there is no operation, the elapsed time T on the counter is 8.
It is determined whether the time has been reached (S6), and if the time has been reached, rice cooking is started (S2). If there is a second operation in S5, the timer 2 is reset (S7), and then the timer is started (S8) to count the elapsed time T.

Further, it is determined whether the timer start switch 7 has been operated for the third time (S9), and if it has not been operated, it is determined whether the count of the elapsed time T of the timer 2 has reached 10 hours (S10), and if it has been, the rice is cooked. Start (S2)
. If the third operation of the timer start switch 7 is performed in S9, the timer 2 is reset (511), the timer is made to count the elapsed time T (S12), and then it is determined whether or not the timer start switch 7 is operated for the fourth time. 8.
13), if there is no operation, it is determined whether the timer count time T has reached 6 hours (514), and if it has reached 6 hours, rice cooking is started (S2). Note that if there is a switch operation in 813, the timer 2 is reset (S15), and the process returns to the timer start S4.
