Description

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

Conventional configuration and its problems Conventional automatic rice cookers have a configuration that washes the desired amount of cooked rice at one time, which not only increases the size of the rice washing tank but also has poor rice washing ability, so a stirring blade is used, etc. The structure was complicated and required a long time of washing the rice. As a result, there are disadvantages in that the rice grains break during washing, and that the rice absorbs the bran together with water during washing, leaving a smell of bran.6 Purpose of the Invention The present invention solves the above-mentioned disadvantages of the conventional method. The automatic rice cooking device of the present invention is designed to reduce the size of the rice and to eliminate broken rice grains and residual bran odor.

By repeatedly repeating the rice washing and preparation steps until the desired amount of rice is reached, and then cooking the rice, the rice washing device can be made smaller and the rice grains can be prevented from breaking and the smell of rice bran remains. Description of an Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the figures, 1 is the automatic rice cooking device main body, 2 is a top plate, and 3 is a rice cooking device provided on the top plate 2. A steam discharge port 4 for discharging steam is a rice bin, and a see-through window 5 made of a transparent material is provided so that the remaining amount of rice in the rice bin 4 can be visually confirmed.

Reference numeral 6 represents a switch operation section, which includes a power switch 7, a start switch 8, a rice cooking amount setting knob 9, and a water adjustment W/4-section knob 10. Reference numeral 11 represents a control circuit section.

Reference numeral 12 denotes a rice measuring chamber for measuring a unit amount of rice, which is provided below the bed 4. Reference numeral 13 denotes the rice measuring chamber 12.
This is a rice washing device installed below, and has a volume sufficient to wash the rice weighed in the rice measuring chamber 12, and a height sufficient to measure an appropriate amount of water for the amount of rice. Reference numeral 14 indicates a drainage receiver 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 lower part of the water supply tank 16. This pump is connected to the water supply tank 16 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. , 19 is 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 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, the drawer 22 is opened and the rice cooker 20 is set on the 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 amount setting knob 9, set the amount of water using the water amount adjustment knob 10, and press the start button 8.
When you press , the rice cooker lid opening/closing device 21 operates and the rice cooker 20
After opening the lid of the rice bin 4, the rice in the rice bin 4 is measured in a rice measuring chamber 12, transferred to a rice washing device 13, and washed in the rice washing device 13 with water pressurized by a pump 17.

After the rice washing is completed, the rice washing device 13 is moved to the top of the rice cooker 2o, and rice and water are charged into a pot in the rice cooker 2Q. When the rice preparation is completed, the rice washing device 13 is moved to its original position. Here, the control circuit 11 compares the set value set by the rice cooking amount setting knob 9 with the number of steps from rice measurement to rice washing and preparation described above, and performs the rice measurement, washing, and preparation until the set value is reached. Repeat the steps up to. When the preparation amount reaches the set value of the rice cooking amount setting size 9, the control circuit 11 proceeds to the next step, the rice cooker lid opening/closing device 21 operates, and the lid of the rice cooker 20 is closed. After that, rice is cooked, and after the rice is cooked, it automatically switches to the keep-warm state.

Effect of the invention As is clear from the above description, according to the present invention.

Weigh and wash rice. Make the container smaller and measure it at - times.

Since the amount of rice that can be washed is reduced, the structure of the main unit can be simplified and still be made compact. Also, 1
Since the amount of rice to be washed at each time is small, the rice washing capacity is high and the rice can be washed in a short time. Further, the user can finely select the amount of rice to be cooked between the minimum amount of rice to be cooked and the maximum amount of rice cooked in the rice cooker, and it is possible to provide an automatic rice cooking device that is very easy to use.
