Title:
POWERLESS HOT WATER PUMPING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/104298
Kind Code:
A2
Abstract:
The present invention relates to a powerless hot water pumping apparatus which receives cold water through a supply pipe equipped with a backflow prevention check valve, and which generates hot water and powerlessly discharges the hot water through a discharge pipe. The powerless hot water pumping apparatus comprises: an electric heater which generates heat when supplied with electric power; an upper cylinder which accommodates the electric heater therein, to the top of which the supply pipe is connected, wherein a steam generating space of a predetermined size is interposed between the inner surface of the upper cylinder and the electric heater; and a lower cylinder which is arranged beneath the upper cylinder, the top of which is in communication with the bottom of the upper cylinder through a connection passage, and to the bottom of the discharge pipe is connected. Hot water generated in the lower cylinder is automatically discharged by the steam pressure which is generated in the steam generating space of the upper cylinder by means of the heat generated by the electric heater.
