Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic rice cooking device having rice storage functions, rice measuring functions, rice washing functions, and rice cooking functions.

Conventional configurations and their problems Conventional automatic rice cookers have a configuration that washes the desired amount of cooked rice at once, which not only increases the size of the rice washing tank but also has poor rice washing ability, so it is difficult to use stirring blades, etc. The structure was complicated and required a long time of washing the rice. This also causes the rice grains to break during washing, and the rice to absorb the bran along with the water during washing.
The drawback was that the smell of rice bran remained.

OBJECTS OF THE INVENTION The present invention is intended to solve the above-mentioned conventional drawbacks, and aims to reduce the size of the rice grains and eliminate broken rice grains and residual bran odor.

Structure of the invention The automatic rice cooking device of the present invention measures a predetermined unit amount,
By repeating the rice washing and preparation steps until the desired amount of rice is reached, and then cooking the rice,
The rice washing device is miniaturized to prevent rice grains from breaking and the smell of rice bran remaining.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the automatic rice cooking device main body, 2 is a top plate, 3 is a steam outlet provided on the top plate 2 to discharge steam during cooking, and 4 is a rice storage chamber. A see-through window 5 made of a transparent material is provided for visually checking the remaining amount of rice. Reference numeral 6 denotes a switch operation section, in which a power switch 7, a start switch 8, a rice cooking amount setting knob 9, and a water level adjustment knob 10 are provided.
11 is a control device. Reference numeral 12 denotes a rice measuring chamber for measuring a predetermined unit amount of rice supplied from the rice storage chamber 4, and is provided below the rice storage chamber 4.
Reference numeral 13 denotes a rice washing device provided below the rice measuring chamber 12, and the rice washing device 13 has a capacity sufficient to store a predetermined unit amount of rice weighed in the rice measuring chamber 12;
It is tall enough to measure less than the appropriate amount of water for the amount of rice. Reference numeral 14 indicates a drainage receptacle provided below the rice washing device 13, 15 indicates a water injection pipe connected to a water supply source (not shown), 16 indicates a water tank for storing water injected from the water injection pipe 15, and 17 indicates a water supply tank 1.
This pump is connected to the lower part of the rice washing device 13 and pressurizes water from the water supply tank 16 to send water into the rice washing device 13. Reference numeral 18 denotes a drain pipe that guides the dirty water from the drain receiver 14 after washing the rice to the outside of the automatic rice cooker main body 1. Reference numeral 19 denotes a steam vent pipe that guides steam generated during rice cooking to the outside of the automatic rice cooker main body 1, and its upper end is connected to the steam discharge port 3. 20 is a rice cooker, and 21 is a rice cooker lid opening/closing device for opening and closing the lid of the rice cooker 20. 22 is a drawer that stores the rice cooker 20.

Next, the operation of the above configuration will be explained. First, open the drawer 22 and set the rice cooker 20 on top of this drawer 22. After that, drawer 22 is closed. Next, turn on the power switch 7, set the desired amount of rice to be cooked using the rice cooking amount setting knob 9, and adjust the amount of water using the water amount adjustment knob 1.
0 and press the start button 8 to operate the rice cooker lid opening/closing device 21 and open the rice cooker 20.
Open the lid. After the rice in the rice bin 4 is weighed in the rice measuring chamber 12, it is transferred to the rice washing device 13, and the water pressurized by the pump 17 is poured into the rice washing device 13.
The rice is washed in step 3. After the rice washing is completed, the rice washing device 13 is moved onto the rice cooker 20, and rice and water are charged into a pot in the rice cooker 20. When the preparation is completed, the rice washing device 13
moves to its original position. Here, the control device 11
compares the set value set by the rice cooking amount setting knob 9 with the number of steps from measuring the rice to washing the rice and preparing the rice described above, and repeats the process from measuring the rice to washing the rice to preparing the rice until the set value is reached. . In this case, for example, if the unit quantity in the rice measuring chamber 12 is 180c.c.
Assuming that the setting value of the rice cooking amount setting knob 9 is 900c.c., the control device 11 executes the process from the first rice measurement to rice washing and preparation, and puts 180c.c. into the pot in the rice cooker 20. Separate the rice and water. Then, repeat this process several times, and by the 5th process, it will be in the pot.
When 900 c.c. of rice and water are charged, the control device 11
The process proceeds to the next step, and the rice cooker lid opening/closing device 21 operates to close the lid of the rice cooker 20. After that, rice is cooked, and after the rice is cooked, it automatically switches to the keep-warm state.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, there are rice measuring methods for weighing a predetermined unit amount of rice supplied from a rice storage room, washing rice for washing the weighed rice, and washed rice for washing rice. This device is equipped with a control device that repeatedly repeats each process of preparing rice and water until the desired amount of rice is reached, and then starts cooking the rice.With this configuration, the amount of rice that can be measured and washed at one time is controlled. Since it is possible to set a small amount of rice, the rice measuring chamber and the rice washing container can be small, and as a result, the automatic rice cooking device itself can be made more compact. In addition, since the amount of rice washed at a time is small, even a small pressurized pump can provide high rice washing capacity, and the rice can be washed in a short time without breaking the rice grains or leaving a smell of rice bran. . Moreover, since the user can finely select the amount of rice to be cooked between the minimum amount of rice and the maximum amount of rice cooked by the rice cooker, it is possible to provide an automatic rice cooking device that is very easy to use.
