The present invention provides an incubator that can maintain a uniform temperature and humidity inside a culture chamber and that does not cause condensation inside the culture chamber. In addition, an incubator is provided in which the air pressure inside the culture chamber is made higher than the outside environment to maintain a sterile environment, and the water vapor supplied does not adversely affect the inside sterile environment. A culture chamber having a heat insulating door and a heat insulating wall, circulation means for circulating air inside the culture chamber, temperature adjusting means for adjusting the temperature of air inside the culture chamber, and the culture Humidifying means for humidifying the air inside the chamber. The humidifying means includes a compressed gas generating means for generating a compressed gas, a water supply means for supplying water, a gas / liquid regulator for adjusting a gas / liquid mixture obtained by mixing compressed air and water, and vaporizing the gas / liquid. And a vaporizer that generates water vapor. Further, the water vapor generated in the vaporizer can be directly supplied to the air circulated by the circulation means without passing through the air filter. [Selection] Figure 1 |
