Abstract: [Object] Although the take-out of liquid from a container by means of syphon tube has a merit of requiring no special structure on the container, activation of siphon is complex, on the contrary. Location of a valve or like in a liquid take-out path for easy activation damages possibility of realization of compact or downsized structure, and increases risk of trouble. [Achieving Means] With a shape of a bent portion of a syphon tube, by adopting a dimension between inner wall portions excellent in capillary effect, there can provide a structure capable of activating siphon only by inclining a container with minimal configuration without locating any movable member.

Abstract: The Present Invention enables energy to be extracted from the atmosphere by creating a vacuum into which atmospheric air is drawn through a vacuum operated motor. The motor operates on the pressure differential between atmospheric pressure at the motor inlet and the vacuum level created by liquid flowing vertically through a tube via gravity. The greater the pressure differential, the greater the airflow through the motor, and the greater the energy extracted by the vacuum motor. The Present Invention is a workable and sustainable vacuum energy recovery system based on siphon principles, and specifically addresses problem areas immediately identifiable to a siphon-based system with air infusion. A scavenger loop operates independently to prevent air and/or gas from accumulating at the siphon apex. Micro-diffusers designed for sweeping effects across the air-liquid interfaces also provide for the optimal ratios of air volumes and bubble sizes compatible with the liquid flow rates within a given siphon.

The source water may be coupled to the humidifier tank via the siphon conduit such that cooler source water may be added during the siphoning action. A method of flushing a hot water humidifier is also included.
