Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker with microcomputer control capabilities.

BACKGROUND OF THE INVENTION In recent micro-coater control type jar rice cookers, for example, when the rice cooker is pressed once, the rice is soaked in water for a period of time (referred to as the pre-cooking period), and the rice is cooked and spun ( (This is called the normal rice cooking operation), and when pressed twice, it immediately performs the rice cooking function without taking the time to soak the rice with water (the main features are the rice cooking operation without pre-cooking and the rice cooking operation). Even in this type of rice cooker, a rice cooking switch that starts the rice cooking operation and a warming switch that starts the warming operation are separately provided.

Problems that Komei aims to solve In rice cookers with this conventional configuration, there are many other switches, such as a switch for setting a one-hour timer for reservations (not detailed in this invention), making it difficult to use them. It sometimes gave some users a vague impression of v1.

Also, even if the rice cooking switch doubles as a heat retention switch,
There is a problem that if you accidentally press the rice cooker switch while cooking rice, it will switch to keep warm mode and you will not be able to cook wJ rice.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide a rice cooker in which the rice cooking switch also functions as a heat retention switch, and in which the rice cooking switch does not malfunction during rice cooking.

Means for Solving the Problems In order to solve the above problems, the rice cooker of the present invention includes a rice cooking switch for starting rice cooking, a rice cooking switch that counts the number of times the rice cooking switch is pressed, and a switch that counts the number of times the rice cooking switch is pressed. An operation determining means that performs normal rice cooking operation, pre-cooking rice cooking operation when pressed twice, and warming operation when pressed three times, and rice cooking when a predetermined time elapses after the rice cooking switch is pressed once or twice. The input to the operation determination means is blocked by the switch.1lIi
This configuration includes a means for preventing the user from using the computer.

Effects According to the above configuration, two cooking operations and a warming operation can be performed with one switch with simple operation, and the number of switches can be reduced compared to the conventional method, giving the user a sense of clutter due to the large number of switches. It is possible to provide a rice cooker that is easy to use and has excellent performance without causing any problems.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a block diagram of a jar rice cooker according to an embodiment of the present invention. In FIG. 1, 1 is a rice cooking switch that starts rice cooking and warming operations. Reference numeral 2 denotes an operation determining means. When the rice cooking switch 1 is pressed once, it outputs an output to the first rice cooking means 3 to allow time for the rice to soak in water and then performs the rice cooking operation. When the rice cooking switch 1 is pressed twice, it outputs an output to the first rice cooking means 3. When the button is pressed three times, the button is output to the warming means 5 to perform the warming operation. At this time, the rice cooking switch 1 is pressed four or more times to receive a -b blessing and the warming operation continues.

On the other hand, the inhibiting means 6 blocks input from the rice cooking switch 1 to the operation determining means 2 after a predetermined period of time has elapsed since the rice cooking switch 1 was pressed once or twice.

Thereby, even if the rice cooking switch 1 is pressed by mistake during rice cooking, the moisturizing operation will not be started.

It is also possible to not start the rice cooking operation immediately when the rice cooking switch 1 is pressed down, but to wait for a predetermined period of time, and when the rice cooking switch 1 is pressed down during that time, to start the operation according to the number of times the rice cooking switch 1 is pressed.

FIG. 2 shows a flowchart of the operation of the jar rice cooker according to one embodiment of the present invention. In FIG. 2, it is determined in step 11 whether the rice cooking switch 1 has been pressed. When the mouth is pressed once, the process moves to step 12, and pre-cooking starts.

Next, in step 13, it is determined whether or not the 2nd time rice cooking switch 1 has been pressed down. I have astigmatism to see how much time has passed. After a predetermined period of time has elapsed, when the soup pot 15 detects the end of the pre-cooking process, rice cooking is started in step 16, and when the completion of rice cooking is detected in step 17, the process returns to step 11. In steps 15 to 17, pressing the rice cooking switch 1 does not work.

On the other hand, if the rice cooking switch 1 is pressed again before the time in step 14 has elapsed, the rice cooking operation proceeds to step 18. Next, in step 19, it is determined whether the rice cooking switch 1 for 3 times has been input. If there is no input and the time in step 19 has elapsed, the process goes to step 17 and the rice cooking is completed. On the other hand, if rice cooking switch 1 is input in step 20, step 2
At step 1, the rice cooking operation is stopped, and at step 22, the rice keeping operation is started. The warming operation continues unless the user terminates it in step 23, and if it is terminated, the warming operation is stopped in step 24 and the process returns to step 11.

Effects of the Invention According to the present invention, it is possible to select and start three operations of normal rice cooking, rice cooking without pre-cooking, and keeping warm with one rice cooking switch, which does not make the user feel complicated due to the number of switches, and is cost effective. We can also provide you with the right rice cooker.

Furthermore, even if the rice cooking switch is pressed by mistake during rice cooking, the rice cooker will not switch to the warming operation and the problem of not being able to cook the rice will not occur.
