(Effects of the invention) As is clear from the description of the embodiments above, according to the invention, the steam generated during rice cooking is mixed with outside air by the exhaust passage and the ventilation means provided in the lid of the rice cooking device. Since it can be dispersed and exhausted outside the rice cooker as low-temperature, moist air, there is no danger of burns if the user accidentally touches the area near the exhaust port, and steam is exhausted forward. As a result, the upper space of the rice cooker can be used effectively, and since the air is dispersed and exhausted as moist air, condensation on walls and the like can be prevented.

In addition, by providing a ventilation passage with a ventilation means in the main body of the device, it is possible to reduce the weight of the lid.
The operability of the lid body, which is frequently opened and closed, is improved.

Furthermore, since the air intake port is not exposed on the front panel, when built into a cabinet such as a system kitchen, it can provide a clean kitchen space suitable for a system kitchen.
