The power switch is turned on, and the rice cooking conditions are set according to each operation of the operation panel 80. After setting various rice cooking conditions, when the start switch is turned on, the operation starts as shown in the rice cooking flow shown in FIG. 11 .

That is, first, after the power switch is turned on (step S1), the setting input of the cooking conditions is performed (step S2), and when the start switch s is pressed (step S3), the rice storage box is measured with the weighing drum in step S4. 4, the set amount of rice is supplied to the rice washing box 5, and the rice is washed in step S5.

The rice washing process of step S5 is composed of the following processes: the bran removal process, which is to stir the rice while running a large amount of water; the rice milling process, which is to temporarily stop the water after water supply and stir the rice in a wet state; The rice is stirred at the water level; and the fine cleaning process is to stir while overflowing the water from the tank.

After the rice washing process of the above-mentioned step S5, the process proceeds to the water amount treatment process of the step S6. In step S7 , the washed rice in the rice washing tank 5 and the water system measured in an appropriate amount of water in step S3 are put into the rice cooker 7 by opening and closing the rice discharge valve 39 .

In step S8, the rice in the rice cooker 7 is immersed in water for a predetermined time. After a predetermined time has elapsed, the ignition is ignited in step S9, the rice is cooked in step S10, the rice is cooked in step S11, and the cooking is completed in step S12, and the predetermined rice is prepared.

Although the soaking step is performed by the rice cooker 7 as described in FIG. 11 , the soaking step may be performed in the rice washing tank 5 , and then the rice cooker 7 may be put into the rice cooker 7 through the appropriate amount of water treatment step.

In addition, before the start switch is turned on, a reservation screen is output by operating the reservation switch, and the rice-cooking completion time is reserved and set, etc., thereby making it possible to complete the rice-cooking at the predetermined time.

In addition, in the above-mentioned embodiment, it is assumed that a predetermined amount of water is ensured while decreasing in order by opening the water level valve 65 from the full state of the rice washing tank for an appropriate amount of water; however, it is not limited to this state, for example, It is a configuration of setting a flow sensor to manage the water supply.

The said ventilation fan 70 is comprised so that it may drive continuously during a rice washing|cleaning and rice cooking operation after the start switch is turned on, and also drive for a predetermined time after a rice cooking operation. With this configuration, the inside of the rice washing box 5 can be dried after the rice cooking operation is completed. In addition, after the rice cooking operation, the state of the drain valve 64 and the rice discharge valve 39 when the blower fan 70 is driven is set so that the rice discharge valve 39 is closed and the drain valve 64 is opened. Therefore, the blowing air by the blower fan 70 is introduced from the extension pipe portion 62c, enters the upper portion of the rice washing box 5 through the horizontal pipe portion 62a, and enters the lower portion of the rice washing box 5 through the vertical pipe portion 62b and the drainage box 60, For air supply only from the upper side, drying efficiency can be improved.

The said drain tank 60 of this Example is provided in the side (right side in the example of FIG. 1) of the rice washing tank 5, and maintenance of the drain tank 60 is easy by this. In addition, the pot lid opening/closing arm 91 described later moves in the left-right direction, and if it is configured to be positioned directly below the drain tank 60 in the lid-opening posture ( FIG. 13 ), the rice washing tank 5 will not be an obstacle when attaching and detaching.

In addition, as for the rice cooker 7, in FIG. 14, the rice cooker 7 is detachably provided with: a container 92; A supply hole 32h is formed in the center portion of the rice cooking lid 100, and a sliding shutter 33S as supply hole opening and closing means is attached so as to be openable and closable so as to block the supply hole 32h.

The sliding shutter 33S is provided so as to be slidable along the guide rails 33a and 33a in the horizontal left-right direction, and is configured such that by opening the supply hole 32h, the rice and water dropped from the rice washing box 5 can be supplied into the container 92 in an appropriate amount. .

Next, the structure which makes the rice washing|cleaning in a rice washing process favorable by making the supplied water contain microbubbles is demonstrated.

As shown in FIG. 15 , a tubular microbubble generator unit 81 having a built-in microbubble generator 81 a is detachably connected to the middle of the main water distribution pipe 46 located behind the rice washing tank 5 . The microbubble generator unit 81 is integrally formed with the tap 110 , and the microbubble generator 81 a is provided on the downstream side of the tap 110 .

The microbubble generator unit 81 is configured such that attachment and detachment members 81b are provided at the upper end and the lower end, respectively, and are respectively detachable from the main water distribution pipe 46 . In addition, the microbubble generator unit 81 is arranged in the vertical longitudinal direction between the left and right pillars 1b and between the horizontal beam 1c and the cover member 23 . In FIG. 15 , the water faucet 110 is described as being backward for convenience, but it is preferable to face diagonally forward in operation. The microbubble generating device 81a is supported by the supporter 112, and is configured so that the supporter and the microbubble generating device 81a can be attached and detached with a tool.

The microbubble generating device 81a is a well-known technique for introducing microbubbles (microscopic air bubbles) into the water when the water passes therethrough.

The water system containing microbubbles by the microbubble generator 81a of this embodiment enters the inside of the rice washing tank 5 through the upper water supply path and the lower water supply path.

In the rice washing process of this embodiment, water is supplied into the rice washing tank 5 from the lower water supply passage, and the rice is washed by the rotation action of the stirring rod 35 . Thereby, the removal of bran, other dust, etc. adhering to the rice surface can be accelerated|stimulated by the action of the microbubbles contained in water. The same applies to the rice milling process and the washing process. In the soaking process in the case of performing in the rice washing tank 5 after the rice washing process, water is supplied from the upper water supply channel. Specifically, a predetermined amount of water is supplied at set time intervals (eg, three-minute intervals). In the soaking process, the stirring bar 35 is in a stopped state. At this time, microbubbles tend to act on the inner wall of the rice washing box 5, so that the rice is difficult to adhere to the inner wall of the rice washing box 5. When the rice in the rice washing box 5 is put into the rice cooking pot 7 after the water amount treatment process, the remaining rice can be reduced. It is difficult for rice to adhere to the inside of the rice washing box 5 . In addition, because the microbubbles enter between the rice and the rice, the rice and the rice can be easily separated, so that the soaking effect is good.
