Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic rice cooker used in general households.

Conventional technology Conventionally, when you press a button on an automatic rice cooker that performs a series of operations from washing rice to adjusting water level and cooking rice 1, the type of rice, how to cook it, the amount of rice to cook, and the level of water are stored in the memory circuit's ROM (IJ-only). memory)
Since the data stored in the rice cooker was used, it returned to the initial state each time rice was cooked, and it was necessary to press the button to change these settings each time rice was cooked. Regarding automatic rice cookers, the type of rice used, the method of cooking, and the amount of water that each user prefers are unique, and even though the amount of rice cooked is generally the same. However, there was a problem in that it was inconvenient as it was necessary to reset the settings each time rice was cooked.

Even if you want to adjust the amount of water so that the quality of the rice is the same, new rice that has not dried up after being harvested in autumn has a high moisture content, but as time passes, the moisture content decreases. There was also the issue of having to change the amount of water depending on the season.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to enable a user to easily set rice cooking according to his or her preference, and to automatically adjust the amount of water depending on the season.

Means for Solving the Problems In order to solve the above-mentioned problems, the automatic rice cooker of the present invention has a rice pot section that can store rice and discharge it in predetermined amounts, a water supply section that supplies water necessary for cooking rice, and a rice bowl section that can store rice and discharge it in predetermined amounts. a control circuit section for controlling discharge, washing, and cooking of rice; the control circuit section includes an operation section for setting a predetermined type of rice, cooking method, amount of rice to be cooked, and amount of water; a clock means; It has a memory circuit that can store and rewrite the amount of rice and amount of water depending on the type of rice and cooking method when rice is cooked once, and the next time the rice is cooked, it will be able to store the previous type of rice, cooking method, and amount of rice. The amount and amount of water are called out and the amount of water is corrected according to the direction of the clock means. Furthermore, when the type of rice and cooking method are selected, the amount of rice and water level previously cooked for the selected type of rice and cooking method are called up.

Operation The present invention has the above-mentioned configuration, and the type of rice, cooking method, amount of rice cooked, and amount of water once cooked are stored in a rewritable memory circuit, and the next time the rice is cooked, the user only has to press the start switch once. This makes it possible to cook rice using the same type of rice, cooking method, amount of rice, and water level as before, and even if the quality of rice changes due to the change of season, it is possible to cook rice in the same way as before.

Even when changing the type of rice or the cooking method, the rice can be cooked using the same amount of rice and water as the previous time.

Example An embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a sectional view showing the overall configuration of this embodiment. The rice cooking section 1 is equipped with a pot 2 for cooking rice and a heating stage 3 for heating the pot 2. Reference numeral 4 denotes a rice bin section, and a rice discharging port 6 for discharging a predetermined amount of rice is provided at the bottom of the rice bin 6 for storing rice.The discharged rice is washed in a rice washing section 7 and then passed through a transfer section 8. and sent to the pot 2. A water supply unit 9 that supplies water necessary for cooking rice includes a water tank 10 and a water pot 2.
Pump 11, water supply vibrator 12, water supply nozzle 1 that supplies water to
It has 3. As shown in Fig. 2, the control circuit section 14 attached to the front of the main body includes a control circuit 16 for controlling each section mentioned above to automatically cook rice, and an operation section for setting the amount of rice to be cooked and the amount of water. 16, a rewritable memory circuit 17 for storing the amount of cooked rice and the amount of water, and a clock means 18.

(Hereinafter, the rewritable memory circuit 17 will be referred to as RAM.) Next, the operation will be explained according to the block diagram of FIG. When cooking rice for the first time, choose the type of rice. How to cook. Standard data regarding amount of rice cooked and amount of water is stored in RAM1.
7, so you can control the type of rice you are using, the desired cooking method such as white rice, steamed rice, or 4D button stiffness, the amount of rice to be cooked, and the amount of water to make it harder or softer than the standard. 16, and press a start switch (not shown in the figure) provided in the operation section 16, the set rice type, cooking method, amount of rice cooked, and water level are stored in the RAM.
At the same time, the set amount of cooked rice is taken out from the rice pot section 4, washed in the rice washing section 7, and put into the pot 2. 1. The pot 2K receives an amount of water from the water supply section 9 according to the set amount of water.

When a set amount of rice and water are prepared, the pot 2 is heated by the heating means 3, and the heating means 3 is controlled while the temperature of the pot 2 is detected by the temperature detection element 20 to complete the rice cooking. All of these series of movements are controlled by the control circuit 16.

When cooking rice for the second time onward, if your preferred type of rice, cooking method, amount of rice, and amount of water do not change, just press the start switch and the rice type and method, amount of rice, and amount of water will be changed from the previous time. The memory circuit 14 is called up, and only the amount of water is corrected according to the season based on the output of the clock means 18 (specifically, less water than the standard is supplied during the new rice season in autumn). , during the period from early spring to new rice, the amount of water supplied is gradually increased above the standard), and the rice cooking is started automatically by the above-mentioned series of operations.

FIG. 3 shows the operation section 16 and display section 23.

1. If you want to change the rice type and cooking method, set the rice type and cooking method using the operation section 13. 1. If you want to change only the rice cooking method, set the rice cooking method using the operation section 13. After making the settings, simply by pressing the start switch 188, rice can be cooked using the same amount of rice and water as the previous time.

1.Although this embodiment shows an example in which the type of rice, how to cook it, the amount of cooked rice, and the amount of water are stored, it is of course possible not to store any of these items.

Effects of the Invention As is clear from the description of the embodiments, according to the present invention, if you first set your favorite type of rice, cooking method, amount of rice to cook, and amount of water, and then cook rice, If your preferred type of rice, cooking method, amount of rice, and amount of water do not change, just press the start switch and the previous type of rice, method of cooking, amount of rice, and amount of water will be recalled from the previous time. As for the amount of water, seasonal fluctuations are corrected and rice cooking starts, and rice cooking is completed automatically depending on the series of operations described above, so you do not have to set the type of rice, cooking method, amount of rice to cook, and amount of water one by one. Since there is no need to press a button, operation is extremely simple.

Furthermore, even if you change the type of rice and cooking method, if the amount of rice and amount of water for the type of rice and cooking method do not change, you can simply press the start switch after setting the type of rice and cooking method. Since the rice can be cooked with the same amount of rice and the amount of water corrected depending on the season, the user does not have to memorize and reset the amount of rice and water for each type of rice and cooking method, making it easy to operate. Reasonable.
