An enclosure formed by a pan and a cover is divided into an upper steam chamber and a lower hot water chamber by a perforate partition. Steam rises through the perforate partition from the hot water chamber to the steam chamber. The cover has a nose aperture into which a user places the nose to inhale steam from the steam chamber. The steam chamber is selectively communicated to the surrounding space on its exterior to control the direction and the amount of airflow between the steam chamber and the exterior. The amount is controlled by a multi-apertured disk on the exterior and the direction by a slide on the interior which can select either bi-directional flow or uni-directional flow in the direction into the chamber. |
