Next, the operation of the rice cooking mode A will be explained with reference to FIGS. 1 and 3. First, turn the setting dial switch 28, which is the rice cooking t1 setting means, and hit the number 29 indicating the desired number of cups. The display f, lJ In means 42 displays the number of cups set on the rice cooking amount display means 16. On the other hand, before or after this setting, the user measures 31 amounts of rice equivalent to the desired rice cooking clay set with the setting daidle switch 28 in the S1 spot cup, and after washing the rice, stores it in the container 5 and stores it in the container 5. Set it to 1 and supply water. As the rod 7 descends in accordance with this weight, the weight is detected by the t sensor 4 and provided to the control means 35. The determining means 43 sets the appropriate amount of water for the set cooking number as the weight of 10 rice water, and compares it with the total ffl value from the fit ffi means 37 to determine how much the measured value is relative to the appropriate value. . Based on this determination result, the display ti 111 means 44 lights up the display section 20 of the water noise display means 17 in stages. In this case, the appropriate value for the amount of rice to be cooked, C, and the amount of rice after cooking, I
Set in a range that is approximately 2.3 times the Mi ratio, that is, that of rice.

This is 5 (cups) x when the amount of rice cooked is 5 cups.
148.5 (Q) +743 (g) is the weight of rice, so 743 (Q) X2.3-1-170
9(Q) is two or three times the weight, and the value obtained by adding the amount of evaporation during rice cooking becomes the appropriate value, and approximately ±IOQ is set as the reference range. When the iJ quasi-range is within this range, the display section 20 corresponding to the character ``鐋'' lights up as appropriate, and based on this, the display section 20 corresponds to the degree of the water amount.
The lighting of will shift up and down.

The operation of rice cooking 8 mode will be explained with reference to FIGS. 7 and 8.

First, when you hear 111, put the desired amount of rice in the container, and press the rice amount switch 27, a signal from the weight sensor 4 is given to the rice cooking darkness determination means 45, and this fit M value is converted to the amount of rice cooked. When this amount is within the rice cooking limit, it is stored and displayed on the rice cooking amount display means 16. After this, the rice is transferred to a rice washing container and washed, and when the washed rice is stored in the container 5 and water is supplied, the determination means 43 determines the appropriate amount of rice + water based on the calculated amount of cooked rice in the same way as in the rice cooking mode A. The degree of deterioration is determined and displayed on the wood display means 11 with respect to the amount of .

In addition, the judgment R1 of the determination means 43 is that Song is cooking f! A notification means 36 notifies you when the rice cooker is out of the cooking possible state.

In the weighing machine, the distortion of the object to be measured, such as rice or water, is checked and the measured value is displayed in units of "9".

In this way, in the above-mentioned embodiment, the setting dial switch 28 serving as the selection means can selectively display the amount of water in the rice cooking mode A, which has good operability, and the water amount display in the rice cooking mode B, which has high accuracy. Therefore, it is convenient to handle and the product value increases. In addition, there is a means for setting the amount of rice cooked in rice cooking A mode! Set the desired amount of rice to be cooked by operating the rice setting switch 28, and set the appropriate amount of water (m) for this setting amount, that is, the appropriate value of rice → water,
Compare this with Keishohani of Yonejusui and find the appropriate value.ffl
Since it is to display the degree of the value, as in the past, first, unwashed rice is placed in the fv device 5 and it is weighed by the weighing means 37, and the weighing result is stored in the memory by operating a switch. It is possible to omit the complicated procedure of transferring the weighed rice from the container 5 to the rice washing container and storing it again in the 'B container 5 after washing the rice, and furthermore, it is necessary to perform a memory operation every time the amount of rice is changed. The user can simply put the desired number of cups of rice into the rice washing container using a measuring cup, wash the rice, and then store the rice in the container 5. .

In addition, since the selection of rice cooker mode and rice cooking B mode and the setting of the rice cooker can be performed using the dial switch 28, mode selection and rice cooking m setting can be made with a series of rotational operations, improving operability and making the next hit. Since you can use this set as is, there is no need to re-centre if the mode is the same and the amount of rice is the same. Furthermore, since the rice cooking A mode and the rice cooking B mode are displayed by the common water amount display means 17, the structure is simplified and the visibility of the display is improved.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, the explanation was given using a rice cooker equipped with a water quantity display device, but as shown in FIG.
+! 11 units 47 may be equipped with a water damage display device. Further, although the rice cooking amount setting means and the mode selection means are formed by dial switches, they can be applied to various switches. For example, as shown in FIG. 12, a push button type rice cooking amount setting switch 28A and a push button type mode selection switch can be used. 28B is provided on the operation panel 12, and each time the rice cooking M setting switch 28A is pressed, the settings are sequentially set from "1" to "101 cup" and displayed on the rice cooker display means IG, and each time the mode selection switch 283 is pressed, the rice cooking mode is changed. 8.
