Description

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

Conventional technology As shown in Fig. 3, this type of conventional rice cooker has a rice cooking menu name, pre-cooking, finished cooking,
The rice cooking operation state, such as additional cooking, is displayed on a display means 1 consisting of a liquid crystal display element, and the current rice cooking menu and rice cooking state are displayed to the user. and,
If there is sufficient soaking time, there is no need to pre-cook the rice, so by pressing the pre-cooking skip switch, the pre-cooking is omitted and the rice is cooked quickly.

Problems to be Solved by the Invention With such a conventional configuration, pre-cooking can be omitted by pressing the pre-cooking omit switch for any rice cooking menu, but when cooking brown rice, pre-cooking can be omitted. If the cooking process was omitted, there was a problem that the rice would become hard and inedible.

The present invention has been made in view of these problems, and an object of the present invention is to provide a rice cooker that can display two or more types of rice cooking menus including brown rice and the rice cooking operation status, and can prevent operational errors when cooking brown rice. The purpose is to

Means for Solving the Problems In order to solve the above problems, the present invention displays the rice cooking operation status such as pre-cooking on a display means in the case of a rice cooking program other than brown rice during the rice cooking operation. The rice cooking program is equipped with a liquid crystal drive means that does not display the pre-cooking information on the display means during the pre-cooking operation, and a pre-cooking omission switch that omit the pre-cooking when cooking rice other than brown rice.

Function By providing the above-mentioned liquid crystal drive means and a pre-cooking omission switch for omitting pre-cooking when cooking rice other than brown rice, pre-cooking cannot be omitted in the case of brown rice cooking, so pre-cooking can be omitted and rice is cooked. It no longer becomes hard and inedible, and when cooking brown rice, the display that displays the rice cooking status does not indicate that pre-cooking is in progress, so if you accidentally press the pre-cooking skip switch to omit pre-cooking, you can do so. Even if the user notices that the switch is effective, he or she will no longer think that the cause is a malfunction, and as a result, there will be no operational errors such as stopping brown rice cooking midway.

Embodiment Hereinafter, an embodiment 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 1 is a display means consisting of a liquid crystal display element for displaying a rice cooking menu and rice cooking status during rice cooking operation, and 2 is a display means for displaying rice cooking operation. 3 is a storage means that stores programs for two or more types of rice cooking menus including brown rice; 4 is a display means for displaying the rice cooking operation status such as pre-cooking when a rice cooking program other than brown rice is used during the rice cooking operation; 1, but in the case of a rice cooking program for brown rice, a liquid crystal drive means does not display the pre-cooking on the display means 1 during the pre-cooking operation, and 5 indicates before omitting pre-cooking when cooking rice other than brown rice. The cooking omission switch 6 is the pre-cooking omission switch 5 and the storage means 3.
This is a control means for controlling the rice cooking means 2 and the display means 1 according to the program.

Figure 2 shows the circuit diagram of the rice cooker.
is a commercial power source. The rice cooking means 2 includes a rice cooking heater 2a, a relay contact 2b, and a relay coil 2c.
The relay coil 2c is controlled to be energized by the control means 6 according to the rice cooking menu program such as white rice, cooked rice, steamed rice, brown rice, etc. stored in the storage means 3, thereby opening and closing the relay contact 2b. controlled. As a result, current flows from the commercial power supply 7 to the rice cooking heater 2a, the rice cooking heater 2a is controlled to be energized, and the rice cooking operation is performed.

On the other hand, the control means 6 outputs the rice cooking menu during the rice cooking operation and the rice cooking operation state such as pre-cooking to the liquid crystal driving means 4. As a result, the liquid crystal driving means 4
drives the display means 1.

If there is sufficient time for rice cooking, the user tries to omit pre-cooking. At that time, if the user presses the pre-cooking omission switch 5, the pre-cooking is omitted. However, in the case of brown rice cooking, the pre-cooking cannot be omitted because if the pre-cooking is omitted, the rice will be hard and inedible. Therefore, when cooking brown rice, if the pre-cooking omission switch 5 is disabled and the display means 1 indicates that pre-cooking is in progress, the user will mistakenly think that the pre-cooking omission switch 5 is malfunctioning, and will perform the operation to cancel brown rice cooking. Since mistakes may be made, in the case of brown rice cooking, the display means 1 indicates that the rice is cooked during pre-cooking.

Effects of the Invention As described above, according to the present invention, the name of the rice cooking menu and the rice cooking operation state during the rice cooking operation are displayed on the display means, and when there is sufficient soaking time, the pre-cooking skip switch can be pressed. , you can cook rice quickly. In addition, in the case of brown rice cooking, if pre-cooking is omitted, the rice will become hard and inedible, so if pre-cooking is prohibited and the rice cooking operation status is displayed, the display will be displayed during the pre-cooking of brown rice. Therefore, even if the user accidentally presses the pre-cooking skip switch in an attempt to omit pre-cooking and realizes that the switch is invalid, the user may think that the cause is a malfunction. As a result, it is possible to eliminate operational errors that often occur when cooking brown rice, and it is also very convenient and allows you to easily cook rice using various menus without making mistakes.
