It is beginning to change. However, when it comes to rice cookers, steam is generated when cooking rice, so there are problems with steam condensation, humidity, temperature, etc.
It was insufficient as a rice cooker.

Hereinafter, the conventional rice cooking device as described above will be explained with reference to the drawings.

FIG. 1 shows a side sectional view of a conventional rice cooking device. In Fig. 1, 1 is the main body of the rice cooker, 2 is the heating device, 3 is the rice cooker, 4 is the lid that covers the top of the rice cooker 3, and 5 is the heating device 2, the rice cooker 3, and the lid 4.
The rice cooker storage 6 that stores the rice cooker has an opening/closing door provided on the front of the rice cooking pot storage 5, 7 is an intake port provided below the opening/closing door 6, 8 is an exhaust port provided above the opening/closing door 6, and 9
1 is an exhaust port provided on the upper back side of the rice cooker storage 5.
0 is an exhaust passage provided on the back surface of the main body 1, and 11 is an exhaust port provided above the exhaust passage 10.

The operation of the rice cooking device configured as above will be described below. When rice and water are put in a rice cooker pot 3 and rice is cooked by heating the rice cooker pot 3 with a heating device 2, steam comes out into the rice cooker pot storage 5 from the gap between the lid 4 and the rice cooker pot 3. Further, the steam filling the rice cooker pot storage 5 is discharged from the exhaust port 8 and the exhaust port 9. Steam discharged from the exhaust port 9 passes through the exhaust passage 10 and is discharged to the outside of the main body 1 from the exhaust port 11.

However, with the above configuration, high temperatures,
Since highly humid steam is discharged into the room, a large amount of moisture accumulates inside the room, and furthermore, condensation occurs on the walls, etc., making it very inconvenient to use.

Furthermore, since the steam being exhausted is at a high temperature, there is a risk of burns or the like if the user accidentally touches it, which also poses a safety problem. Furthermore, there was a drawback that dew condensation and water droplets adhered to the inner wall of the rice cooker storage 5 and the inner wall of the opening/closing door 6, making them susceptible to corrosion.

In other conventional rice cookers, an exhaust fan is installed in the rice cooker storage to forcibly exhaust steam. In this method, although the temperature of the exhausted steam is lowered, a large amount of moisture is discharged into the storage compartment and into the room, resulting in the same problems as in the conventional example.

Purpose of the Invention The rice cooking device of the present invention solves the above-mentioned conventional problems, and allows easy treatment of condensed water after steam generated during rice cooking is treated with a steam processing device.
Another object of the present invention is to provide a rice cooking device that is easy to use.
