Abstract

PURPOSE:To systematize rice cooking by dropping electrically and automatically measured rice into a rice polishing hopper in which water injection and drainage is electrically, automatically carried out, and after having been polished by a rice polishing member, by storing it together with an appropriate quantity of water in the inner kettle of a rice cooker through an open/close valve. CONSTITUTION:The rotary solenoid 4 of a measuring apparatus C is driven, and a measuring device 5 is reciprocatedly turned as many as a required times, thereafter, a desired amount of rice is taken out from a rice chest hopper B, and is dropped into a rice polishing hopper D below. Then, the water injection valve 10a in a water injection pipe 10 is opened, and water is injected into the rice polishing hopper D. The water quantity is detected by a level sensor, thereby a rice polishing screw 9 is started to carry out rice polishing. In a control unit, the water quantity corresponding to the amount of rice to be taken out from the measuring apparatus C is previously stored and set, so that when the water quantity detected by the level sensor decreases to an appropriate quantity, a drainage valve is closed, thereby the adjustment of water quantity can be carried out. Both the rice and water inside the rice polishing hopper D are simultaneously discharged into the inner kettle G of a rice cooker at the bottom. Then, a kettle housing part E in the frame A of the equipment is operated to carry out cooking.

Furthermore, each component of the device n of the present invention is sequence-controlled according to a predetermined procedure, and is provided with a control device consisting of an electronic circuit or a microcomputer.

Next, the operation and control of the device of the present invention will be explained in more detail.

Start with rice stored in the unknown hopper B. First, the rotary solenoid 4 of weighing device C is driven, and the meter:
The U-masu 5 reciprocates the required number of times, and a desired amount of rice is taken out from the rice bowl hopper B and falls into the rice polishing hopper D below. After the rice is received in the rice polishing hopper D, the water injection valve 10a of the water injection pipe IO connected to the water pipe in the rice polishing hopper 1) is opened to inject water into the rice polishing hopper D. When the water M in the rice polishing hopper 1) reaches an overflow level, the level sensor 26 detects this and starts the rice polishing screw 9 to polish the rice. Incidentally, since the amount of water to be poured and the capacity 1 of the rice polishing hopper D are known, the start timing of the rice polishing screw 9 may be determined by a timer. During rice polishing, the water injection pipe 10 continues to inject water, so the supernatant liquid will overflow! The water is drained out of the rice polishing hopper D from 3. The rice polishing time may vary depending on the type of rice, for example 3.
It is set to be adjustable to about 10 minutes, and is stored in the control device. With the end of rice polishing.

Close the water injection valve lOa and stop water injection +h. After polishing the rice. The amount of water in the rice polishing hopper D is adjusted according to the amount of rice taken out at will to determine the hydraulics for proper rice cooking. This is done by opening the drain valve +1a and using the rice polishing hopper D.
This is done by detecting the water level with the level sensor 26 while draining the water inside, and 1j-t of the water corresponding to τd of rice to be taken out from the meter C is stored in advance in the control device. Yes, water detected by level sensor 26: 1t
The amount of water is adjusted by closing the drain valve +2 when the water level has decreased to an appropriate level t1. In addition, since the water level is at an overflow level immediately after rice polishing is completed, water saving may be determined by controlling the draining time from the drain pipe 11 based on that level.

After adjusting the amount of water in the rice polishing hopper D, drive the plunger solenoid 17 to open the lid 14 provided at the lower end opening 15 of the rice polishing hopper 〇, and remove the rice and water in the rice polishing hopper D. At the same time, pour the rice into the lower inner pot G of the rice cooker.

Then, the inner pot is set in the rice cooker E, and the rice is cooked by operating it in the container accommodating portion E of the device frame or at another location.

Furthermore, after completing the rice polishing process, a water-filling vibe is applied!
The inside of the rice polishing hopper D may be cleaned by spraying water from 9. In this case, a considerable amount of water may be collected in the rice polishing hopper 1) after draining water, and the rice polishing screw 9 may be rotated.

In addition, there is a water-filling vibe! Water is sprayed from 9 to flush the rice grains adhering to the inner wall of the rice polishing hopper D into the inner pot G of the rice cooker along with the water. Further, it is preferable to determine the appropriate 1E water level at the time of adjusting the water amount by taking into consideration the injection from the water injection vibrator 19. That is, when adjusting the amount of water, it is sufficient to discount the amount of water injected from the water injecting vibrator by f.

In addition, in the device of the present invention, a detector is installed on the platform F of the container storage section E, and the detector is installed on the platform D so that the device will not operate unless the inner pot G is placed on top of it. Equipped with a circuit. Furthermore, the water injection pipe 10 may be omitted and water may be injected only from the water injection vibrator 9.

In addition, settings such as setting the rice polishing time 5 and adjusting the amount of water for cooking (opening control time of the drain valve 11a) are set in advance in the memory of the control device, and the series of device operations described above is controlled by the microcomputer provided in the device. This is carried out according to the sequence control of the control unit such as.

[Effects] With the above-described configuration, the present invention automatically and continuously adjusts the amount of rice stored in the rice storage hopper, the amount of water for polishing the rice, and the amount of rice stored in the rice cooker within a short period of time. By doing so, it is possible to reduce the labor of housewives who are busy with household tasks every day. By incorporating it into a system kitchen, it has the effect of increasing cooking efficiency.
