Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cooker for general household use.

2. Description of the Related Art As shown in FIG. 4, a conventional rice cooker of this type has a rice cooking means 1 for performing a rice cooking operation, a storage means 2 for storing a rice cooking menu program, and when pressed once, the rice cooker cooks rice sufficiently. Rice cooking start switch 3 starts cooking with pre-cooking for soaking in water, and presses twice to start cooking without pre-cooking, and press to select the white rice high-speed cooking menu that cooks rice in a short time over high heat. switch 4 and these switches 3,
4 and a control means 5 for controlling the rice cooking means 1 according to the program in the storage means 2.

Normally, when cooking rice, the rice cooking start switch 3 is pressed once to pre-cook the rice over low heat to submerge the rice in water, and then to cook over high heat. In addition, if you have enough time to cook the rice and want to let the rice soak in water naturally without pre-cooking and then cook it over high heat, press the rice cooking start switch 3 twice to skip the pre-cooking operation and continue cooking as is. It goes into action.

However, if there is not enough cooking time, the rice may be cooked all at once over high heat. In this case, if the rice cooking start switch 3 is pressed and then the high speed rice cooking switch 4 is pressed, the high speed rice cooking operation using high heat will start. This allows the user to cook rice in a short time even if there is not enough time for cooking rice.

Problems to be Solved by the Invention However, in such a conventional configuration, it is difficult to start cooking rice.
Since two switches are required, the pre-cooking omission switch 3 and the high-speed rice cooking switch 4, the operation is not only very complicated, but also when performing high-speed rice cooking, the high-speed rice cooking switch 4
However, there was a problem in that if you pressed only the rice-cooking start/pre-cooking skip switch 3 by mistake, the rice cooking failed.

The present invention solves these conventional problems and aims to provide a rice cooker that allows the user to easily cook rice at high speed without making any mistakes.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a rice-cooking operation means comprising a rice-cooking heater for performing a rice-cooking operation, a control element for controlling the heating power of the rice-cooking heater, and the rice-cooking operation means. A storage means that stores a rice cooking menu program as a rice cooking operation process, and the rice cooking menu includes rice cooking including a pre-cooking process of submerging the rice with water at low heat, rice cooking without the pre-cooking, and start of high-speed rice cooking using high heat. The rice cooker has a structure in which a switch and a control means for controlling the rice cooking means according to the switch and the program in the storage means are added.

Function According to the above configuration, a switch is provided that combines rice cooking with pre-cooking, rice cooking without pre-cooking, and high-speed rice cooking, so when a user wants to cook rice without pre-cooking, he/she can switch one switch to 2. When performing high-speed rice cooking, press the button three times to start cooking rice.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 shows a block diagram of a rice cooker according to an embodiment of the present invention, in which 6 is a rice cooking means consisting of a rice cooking heater and a rice cooking heater control element for performing the rice cooking operation, and 7 is a storage device for storing a rice cooking menu program. 8 is a switch to press when starting rice cooking, when pre-cooking is omitted, and when high-speed rice cooking is performed, 9
is a control means for controlling the rice cooking means 6 according to this switch 13 and the program in the storage means 7.

Fig. 2 shows a block diagram of only the rice cooking means of the rice cooker, in which 10 is a commercial power supply, and the rice cooking means 6 is connected to a rice heater 6a and a relay contact serving as a rice heater control element. Relay 6 consisting of 6b and relay coil 6C
When the switch 8 is pressed, the control means 9 controls energization of the relay coil 6C to control the opening and closing of the relay contact 6b according to the rice cooking menu program stored in the storage means 7. As a result, current flows from the commercial power supply 1o to the rice cooking heater 6a to perform the rice cooking operation.

The flowchart shown in FIG. 3 shows the rice cooking operation in this case. First, if the switch is not pressed, step 1
Then, it waits for the switch to be turned on, and when the switch is pressed once, it proceeds to step 2. Here, it is determined whether the switch has been pressed twice or not, and if it is not pressed, the pre-cooking operation begins, and if it is pressed twice, the process proceeds to step 5. The completion of the pre-cooking operation in step 3 is determined in step 4, and if it has not been completed, steps 2 to 4 are repeated. If the switch is pressed for the second time during this pre-cooking operation, the pre-cooking operation is aborted and the process proceeds to step et al. In step 6, it is determined whether the switch has been pressed for the third time, and if the switch has been pressed for the third time, the high-speed rice cooking operation in step 8 is started. If the button is not pressed a third time, the rice cooking operation starts in step 6. In this case, if it is determined that the pre-cooking operation is finished in step 4 and the process proceeds to step 6, the rice cooking operation will continue.

In step 6 rice cooking and step 8 high-speed rice cooking, the rice cooking or high-speed rice cooking operation continues until it is determined to be finished in step 9 and step 9, respectively.

Effects of the Invention As is clear from the above description of the embodiments, the present invention is equipped with a switch for starting rice cooking with pre-cooking, rice cooking with pre-cooking omitted, and high-speed rice cooking. You can do the rice you want by just pressing the button twice when doing quick rice cooking, or three times when doing high speed cooking.

As a result, there is no need for a switch to select the high-speed rice cooking menu, which simplifies the configuration of the control panel and makes operation extremely easy. This also eliminates the possibility of making mistakes when cooking rice.
