Description of the Related Art As a humidifier for generating water vapor by boiling water and releasing the water vapor into a room for humidification, a pot type for directly heating and evaporating water contained in a pot-shaped container, and a humidifier for putting it in a tank. There is known an evaporator type in which water is temporarily transferred to an evaporator and heated and evaporated in the evaporator.

The above-mentioned pot-type humidifier is characterized in that since the entire container is heated to a high temperature, the temperature difference inside is small, and thus the amount of dew condensation is small and a sufficient amount of steam can be obtained. For this reason, a blower for promoting the release of steam has conventionally been unnecessary.

On the other hand, an evaporator-type humidifier heats a small evaporator installed in a part of the inside of the humidifier to generate steam, so that the temperature difference inside the humidifier is large. For this reason, dew condensation increases and the amount of released steam decreases, so that a blower is installed to promote the release, and an outlet for air sent from the blower is provided near the opening of the evaporator. (For example, see JP-A-8-327100).
