Description

TECHNICAL FIELD The present invention relates to an automatic rice cooker used in general households.

2. Description of the Related Art Conventional automatic rice cookers that perform a series of operations from washing rice to adjusting water and cooking rice by setting the type of rice and the prescribed method of cooking, the amount of rice cooked and the amount of water adjusted How to cook, the amount of rice cooked and the amount of water
Since it is stored in the only memory) or RAM (random access memory), there is no problem when putting white rice in rice vines, but other than white rice such as brown rice, germinated rice, and rice with sorting rice. When using with rice,
In the case of the ROM storage method, the rice type returns to the initial state each time it is cooked, so it is necessary to reset the rice type each time the rice is cooked. , I had to reset the rice type each time.

Problems to be Solved by the Invention In such a conventional method, when rice other than white rice is put in the rice bin, if the rice type is forgotten and the rice is cooked, the optimum amount of water for the white rice and the heat adjustment will be achieved. In order to cook
There was a problem that it would result in poorly cooked rice.

The present invention solves such a problem, and an object of the present invention is to provide an automatic rice cooker that does not need to reset the rice type each time rice is cooked or the power is turned off. .

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is a rice cooker comprising a pot for heating rice and a heating means, a rice pot that can store rice and discharge it by a predetermined amount, and the discharged rice. It has a rice washing section for washing rice, a water supply section for supplying water necessary for cooking rice, and a control circuit section for controlling each of these sections, and the control circuit section regulates a predetermined cooking method and the amount of cooked rice and the amount of water. An operating unit for setting, a changeover switch capable of setting the type of rice, a type of rice set by the operating unit and the changeover switch,
It is provided with a storage circuit that stores a predetermined cooking method, the amount of cooked rice, and the amount of water added.

Further, in the automatic rice cooker of the present invention, the control circuit section includes a non-volatile memory circuit that stores the type of rice set by the changeover switch and does not disappear even when the power is turned off.

Operation According to the above configuration, the control circuit unit sets the predetermined cooking method, the amount of rice cooked and the amount of water added, the changeover switch that can set the type of rice, and the operation unit and the changeover switch. Since it has a storage circuit that stores the type of rice and the prescribed cooking method, the amount of cooked rice and the amount of water added,
If the type of rice put in the rice bin is set with the changeover switch, it will be stored in the memory circuit later, and as a result, it is not necessary to reset the type of rice each time rice is cooked.

Further, since the control circuit section has a non-volatile memory circuit that stores the rice type set by the push switch and does not disappear even when the power is turned off, it is necessary to reset the rice type each time the power is turned off. Will disappear.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows an overall configuration diagram of an automatic rice cooker according to an embodiment of the present invention. 1 is a pot for cooking rice, 2 is a heating means for heating the pot 1, and 3 is rice. The rice container part 4 is a rice outlet for discharging a predetermined amount of rice, 5 is a rice washing part for washing the rice discharged from the rice outlet 4, 6 is a rice washing part 5
A transfer part for transferring the rice washed in step 1 to the pan 1, a water tank 7 for storing water necessary for cooking rice, a water supply pump 8 for supplying water to the pan 1, and a water supply 9 for sending water to the pan 1. A pipe, 10 is a water supply nozzle for discharging water to the pan 1, 11 is a control circuit unit, and this control circuit unit 11 controls each of the above units to automatically cook rice as shown in the block diagram of FIG. Control circuit for 12
An operation unit 13 for setting a predetermined cooking method, the amount of rice cooked and the amount of water added, and a changeover switch 14 for setting the type of rice.
A storage circuit 15 for storing the type of rice, a predetermined cooking method, the amount of cooked rice, and the amount of water added, and a display unit 18.

FIG. 2 shows a block diagram of an automatic rice cooker according to an embodiment of the present invention, and its operation will be described with reference to the block diagram of FIG.

First, when the power is turned on, the control circuit 12 changes the switch 14
Check the state of, and write the type of rice set in the memory circuit 15 according to the state.

Next, set the prescribed cooking method, the amount of cooked rice, and the amount of water to be adjusted through the operation unit 13, and press the start switch to release the set amount of cooked rice from the rice bin 3 and wash it in the rice washing unit 5 to prepare a pan. Enter 1. In addition, the amount of water that matches the set amount of water and the type of rice enters the pan 1 from the water supply unit 8.

When the set amount of cooked rice and the adjusted amount of water are prepared in the pan 1, the heating means 2 heats the pan 1, and the temperature detector 16 detects the temperature of the pan 1 and the heating means is set according to the type of rice set. Control 2 to complete cooking rice.

All of these series of movements are controlled by the control circuit 12.

FIG. 3 shows another embodiment of the present invention.
In the figure, the control circuit unit 11 shown in FIG. 2 is provided with a non-volatile memory circuit 17 that stores the type of rice set by the push switch 19 and does not disappear even when the power is turned off. According to this configuration, since the type of rice set by the push switch 19 is stored in the nonvolatile memory circuit 17, the memory is retained even when the power is turned off, and as a result, each time the power is turned off. There is no need to reset the rice type.

EFFECTS OF THE INVENTION As described above, according to the present invention, the control circuit unit sets the predetermined cooking method, the amount of cooked rice, and the amount of water added, the changeover switch that can set the type of rice, and the operation unit and Since it has a storage circuit that stores the type of rice set by the changeover switch, the prescribed cooking method, the amount of cooked rice, and the amount of water added, first, the changeover switch that can set the type of rice is used to match the rice in the rice bin. If you set the type of rice by pressing the start switch, the set type of rice and the prescribed way of cooking, the amount of rice cooked and the amount of water added are called from the memory circuit to start rice cooking The operation automatically completes the rice cooking, and as a result, it is not necessary to reset the rice type each time the rice is cooked.

In addition, the control circuit section has a non-volatile memory circuit that stores the rice type set by the push switch and does not disappear even when the power is turned off.Therefore, even if the power is turned off, the rice type is set each time. It does not need to be fixed.
