The device of the present invention is provided with a drain port, and various hoses (tubes), wires, and the like are connected to allow a drawing stroke. Next, an operation mode of the embodiment of the present invention will be described. In FIG. 1, when the rice storage 1 with a predetermined amount of rice replenished is inserted into a predetermined position in the box, a sensor (not shown) detects the rice storage, and at the same time, the presence or absence of rice is detected by the sensor S. You. Similarly, when the rice washing mechanism 7 is inserted at a predetermined position, a sensor (not shown) detects this, and when the rice cooker 38 is further inserted at a predetermined position, a sensor (not shown).
Detects this. The presence or absence of the inner pot 41 of the rice cooker 38 is detected by a sensor 48.

As described above, the start-up preparation is completed only when all the sensors operate. On the other hand, after inputting data such as a desired amount of cooked rice, water addition and subtraction, immersion time, steaming time, and cooking time from the console panel 67, when the start button is pressed, the rice storage 1, the rice washing mechanism 7, and the rice cooker 38 are pressed. Lock means 6, 15, and 39 are simultaneously operated to lock all the mechanisms in the refrigerator. In the above state, the start signal can be received.

After the start signal is input, it is confirmed that the conical valve 28 that seals the rice washing mechanism 7 is closed. Then, the metering means 2 rotates and a predetermined amount of milled rice passes through the chute 30 into the rice washing tank 12 of the rice washing mechanism 7. Let it fall. Upon completion of the quantification, the stirring means 8 rotates, the electromagnetic valve 19 opens, and water spraying is started from the fountain nozzle 20 as indicated by the dotted line 20A in FIG. The rice-washed wastewater in the rice-washing tank 12 passes through a perforated plate 25 provided in a drainage jacket 24 at the bottom, passes through a drainage port 10 that can be opened and closed, and is drained out of the system from a drainage gutter 27.

When the rice washing process for a predetermined time is completed, the rice washing tank 12
The watering inside is temporarily interrupted, and the process shifts to a polishing rice process in which only the stirring means 8 rotates. During this time, the solenoid valve 34 is opened and the constant water level tank 2 is opened.
Water supply is started at 2, and once water supply is stopped at the water level of the water level sensor 33, water is stored up to the overflow port 31. After repeating the rice washing step and the rice polishing step a predetermined number of times, the process proceeds to a rinsing step.

In the rinsing step, after the on-off valve 26 is closed and water is stored in the rice washing tank 12 to a predetermined water level, the on-off valve 26 is opened and drainage is performed at once. The purpose is to clarify. In the embodiment of the present invention, a maximum water level (maximum water storage level) corresponding to a preset amount of cooked rice, for example, a water amount of 30% increase of an equal water level is used as a water amount for one fixed rinse. It has a very high effect on clarification and water saving of wastewater. That is, in the rinsing step, the electromagnetic valve 21 of the conduit 23 opened to communicate with the bottom of the constant water level tank 22 is opened, and at the same time, the electromagnetic valve 34 is opened to open the rice washing tank 12.
Start water supply within. Since the water level H in the constant water level tank 22 is kept constant by the overflow port 31, the flow supplied by the solenoid valve 21 is always constant.

Therefore, by opening the solenoid valve 21 for a preset time, an accurate water storage amount is secured. The flow rate flowing from the water supply solenoid valve 34 is controlled by the solenoid valve 21.
The flow rate is adjusted so as to be equal to or slightly larger than the sum of the outflow rate and the overflow amount from the overflow port 31. Therefore, the water level H can always be kept stable. The rinsing process is repeated several times, and when the drainage of the rice washing tank 12 is completed, the process proceeds to the water adding / decreasing process. The on-off valve 26 of the drain port 10 is closed, and the solenoid valve 21 is opened for a preset time to perform water control. Simultaneously with the completion of water addition, the shutter 5 is driven by the shutter drive mechanism 55.
3 opens the opening 52 which is an inlet for rice and water provided in the upper lid 42. Upon detecting the opening of the shutter 53, the conical valve 28 opens and the rice and water are discharged into the inner pot 41.

The rice and water discharged from the rice washing tank 12 flow down in a hollow radial manner along the slope of the conical valve 28. As a result, the rice deposited in the inner pot 41 exhibits an ideal distribution curve, and No means are needed to level the surface. On the other hand, when the rice is discharged from the rice washing tank 12, the stirring means 8 is rotated for a short time at the same time as the opening of the conical valve 28 in order to enhance the rice discharging effect.

Here, when the amount of rice to be treated is small, a large amount of rice grains may remain particularly at the bottom of the tank, and a large amount of rice grains may adhere to and remain in the portion indicated by the symbol D in FIG. Therefore, in the embodiment of the present invention, water is sprayed from the fountain nozzle 20 for a predetermined short time at the final stage of the rice discharging process, that is, when the rice in the rice washing tank 12 is almost completely discharged. The remaining rice is washed away instantly.

The amount of water used for this washing is constant regardless of the amount of rice, and is added to the amount of water added or subtracted. This means that the amount of water that evaporates during cooking is almost constant regardless of the amount of cooked rice. Can be eliminated. The conical valve 28 that has been opened for a predetermined time for the above-described cleaning, that is, for processing the remaining rice, is automatically closed. When the closing of the conical valve 28 is detected, the shutter driving mechanism 55 rotates in reverse to close the shutter 53.

With the above, the rice washing process is completed, and the process proceeds to the immersion process. If only the rice washing process is selected and set in advance, the automatic operation ends here, and the locks of all the mechanisms are released, and the rice can be pulled out from the box. When the preset immersion time has elapsed, the power supply to the heater 46 is started, and the process proceeds to the rice cooking process. After a predetermined time elapses after the start of the rice cooking process, the steam exhaust means 70 having a fan is activated to exhaust steam to the outside of the system. Completion of rice cooking is detected by the sensor 47, and then the process proceeds to the steaming step. The rice cooker 38 has a built-in heat retention control circuit, detects a decrease in the temperature of the inner pot 41, and is configured to automatically keep the temperature after the steaming process is completed. At the end of the steaming step, the lock of the rice cooker 38 is released and the rice cooker 38 can be pulled out from the box 5.

With the above, a series of operation steps in the device of the present invention is completed. To perform regular internal washing (cleaning) of the rice washing tank 12, the locking means 15 is released,
The rice washing tank 12 is moved in the horizontal direction, that is, as shown by the arrow B in FIG. 1, to a position where there is no rice cooker 38, and the inner wall of the rice washing tank 12 and the stirring means 8 are supplied from the water supply means 20 and 23. , The garbage and the like adhering to these are supplied with water and washed off. For cleaning at this time, a bucket (container) or the like is placed in a space below the rice washing tub 12,
This is to prevent scattering on the floor surface, and after washing is completed, the rice washing tank 12 is pushed in and locked by the lock means 15 again.

The commercial rice cooker according to the embodiment of the present invention having the above-described structure and operation mode eliminates the complexity of the rice cooking operation at all, and sets the rice cooker at a desired time just by setting a timer. In addition to the epoch-making value of being able to eat hot rice, it has many advantages as follows. The rice cooker according to the embodiment of the present invention is configured such that each mechanism is independently configured and movable from the box, so that it is convenient for replenishing rice and the top plate can be used as a cooking table or a storage space. In particular, it has many advantages such as easy cleaning of the rice washing mechanism that requires cleaning management, easy inspection of each part, and easy replacement of each mechanism or part in case of failure. is there.

Further, by providing a rice cooker having a shutter which can be freely opened and closed in the horizontal direction provided on the upper lid, the rice cooker can be set in the apparatus main body with the upper lid closed, so that the overall height of the apparatus is significantly increased. It is possible to realize a highly practical device that can be reduced and can be provided in a compact size that can be stored in a system kitchen in addition to a single unit type.

Further, as for the water supply means, the complexity of the structure and poor cleanability found in the conventionally proposed float type, moving electrode type or fixed-quantity water storage type, and water level detection caused by dirt, change in water quality, etc. In view of many problems such as frequent errors, the adoption of a digital control method using a constant water tank completely eliminates the above problems and has the advantage of being able to accurately control the micro water volume range. is there.

Although the embodiment of the present invention is as described above, the following setting change is free. Rice can be replenished each time from the cylindrical body of the rice washing mechanism.In addition, for example, a structure that replenishes rice by opening and closing or sliding the top plate with a fixed water storage, or a meter for measuring rice in the rice storage The structure in which only the hopper is removed and the previously quantified rice is supplied in each case, and the design change of the metering machine, etc., all belong to the technical scope of the present invention.
