After the specified cooking time is completed, the rice cooker 116 goes through a steaming process.During this time, the rice cooker 116 is located at the front of the box, so it can be easily taken out of the box, and it can also be removed by pulling out the frame 122. It can also be removed from the box body 1.

After discharging the rice and during rice cooking, with the on-off valve 78 closed, the water supply from the water supply means 87 is turned on to sprinkle water into the inner tank 15 from the nozzles 95 and 96, and the stirring means 18 is driven. By doing so, by removing water scale in the inner tank 15 and water scale adhering to the stirring means 18, and by programming a cleaning process, it is also possible to discharge dust, leftover rice, etc. from the discharge jacket 57 to the outside of the machine.

In addition, in the above, when water is supplied to the inner tank I5 until it is full and the upper float 172 is repeatedly turned on and off, and the float 172 remains on even after a predetermined period of time has elapsed, it means that the drainage system is clogged with dirt, etc. It is also possible to incorporate a program that detects this with an alarm and turns off the solenoid 92.

After the rice cooking process is completed, in order to replenish the ice storage 3 with polished rice, the ice storage 3 is pulled out to the front, and the rice washing device 1
3 is also accompanied and moved horizontally to the front of the box 1, as shown in FIG.

Therefore, while removing the on-off valve 78, the suspension member 29.
30 is operated in the direction of the arrow shown in FIG. 20 to release the suspended state of the rice washing tank 17, and the rice washing tank 17 is dropped as shown by the arrow in FIG. 21, exposing the stirring means 18. As a result, cleaning inside the rice washing tank 17 and cleaning and maintenance of the stirring means 18 can be easily performed.

Furthermore, after dropping the rice washing tank 17 and taking it out, the stirring means 18 is separated from the driving body 72 through the separation part 73, and the stirring rods 67 to 70 are pulled out downward.
We can also clean and maintain the entire 70.

When the specified cleaning and maintenance are completed, the stirring rod 67~
70, set the rice washing tank 17 in a suspended manner from below, and then set the on-off valve 78. It can be adjusted by screwing in, etc.

In addition, in the illustrated embodiment described above, the rice washing tank 17 is
