Embodiment 1

[0026] Fig. 1 is the block diagram of the electric cooker in the embodiment 1 of the present invention.

[0027] The setting operation device 1 among Fig. 1 is used for setting the various functions of electric cooker and sends out the operation instruction such as cooking, wherein is provided with function selection switch 1a, function setting change switch 1b, cooking start switch 1c, timing setting. Switch 1d, keep warm start switch 1e, setting / operation cancel switch 1f and other switches.

[0028] The function selection switch 1 a is a switch for selecting / setting a function from a plurality of rice cooking functions such as operation mode selection and rice brand selection, and a signal generated by the function selection switch 1 a is input to the control device 4 . When the control device 4 receives the above-mentioned input signal, it transfers the function selection state from the currently selected function to the next function. The function setting change switch 1...

Embodiment 2

[0043] FIG. 5 shows a block diagram of an electric rice cooker in Embodiment 2 of the present invention.

[0044] In Fig. 5, a timing device 5 for measuring time is added, specifically timing the elapsed time from the last setting operation timing. The control device 4 turns off the light emitting device 3 until the time T1 counted by the timer device 5 reaches a predetermined time T2. The other constitutions are the same as those of the above-mentioned embodiment 1, so only the same symbols are assigned, and the description thereof is omitted here.

[0045] Next, referring to FIG. 6, description will be given of the operation when the setting operation is performed in the above configuration. First, in step S1, the control device 4 judges whether the user is performing a setting operation through the setting operation device 1, if it is determined that the setting operation is not being performed, then proceed to step S2; if it is determined that the setting operation is bei...

Embodiment 3

[0049] In this embodiment, when the switch corresponding to the light-emitting device 3 in the blinking state is operated, the control device 4 makes the function setting operation of the light-emitting device 3 currently in progress corresponding to the operated switch Keep off until finished. Other constitutions are the same as in Embodiment 1 above.

[0050]The operation of the setting operation performed in the above configuration will be described below with reference to FIG. 7 . First, in step S11, the control device 4 judges whether the setting operation device 1 is performing the setting operation, if it is determined that the setting operation is not being performed, then proceed to step S16; if it is determined that the setting operation is being performed, then proceed to Step S12. In step S12, the control device 4 judges whether the setting operation performed in step S11 changed the function selection by the function selection switch 1a. If it is judged not to ...

Abstract

The invention will not make the user feel confused even if one switch has many functions, and the invention is able to reliably make correct operation so as to increase operability. The set operating device (1) is composed of multiple switches containing alternation switch (1b) with common function set, and luminous devices (3c) are set in at least two switches. In set operation process of every function, the control device (4) only makes the luminous device (3) corresponding to the switch spark or shine in the condition that only one switch can be operated and only one switch can be operated likely by the user even if multiple switches exist and are able to be operated. If many switches exist and are able to be operated in the following and many switches are likely to be operated by the user, all the luminous devices corresponding to the switches will spark or shine.

Description

technical field [0001] The invention relates to an electric rice cooker capable of setting cooking functions such as operation mode selection and rice brand selection through a switch. Background technique [0002] In recent years, various functions have been added to rice cookers in order to make rice in the best state according to the user's preference. Such an electric rice cooker can control various conditions such as heating temperature and heating time, thereby making uncooked rice into an optimal cooked state. The types of rice that are cooked in the rice cooker include white rice, unwashed rice, coarse rice, etc., and there are various brands of various types of rice. Different kinds of rice have different conditions such as heating temperature and heating time in the electric rice cooker, so the user needs to set different settings for the electric rice cooker according to the different rice to be cooked. [0003] In addition, in recent years, rice cookers are als...
