Claim Text:
1. A bubble extinction machine comprising: a hot water storage tank; a hot water introduction pipe for introducing hot water containing bubbles to the hot water storage tank; a discharge pressure adjusting device; a first vertical main pipe; a second vertical main pipe; a plurality of flow pipes; a hot water suction pipe; a first spiral drum; and a second spiral drum, wherein an end of the hot water introduction pipe is connected to the discharge pressure adjusting device and horizontally disposed in a vicinity of an upper side wall of the hot water storage tank, so that hot water containing bubbles is introduced from a hot water supply unit into the hot water storage tank via the discharge pressure adjusting device, another side of the hot water introduction pipe is vertically bent downward inside the hot water storage tank to be connected to a first vertical main pipe, and a lower end of the first vertical main pipe extends to the vicinity of a lower portion of the hot water storage tank, the second vertical main pipe is disposed in parallel on the side of the first vertical main pipe, each said flow pipe is horizontally disposed between the first vertical main pipe and the second vertical main pipe at predetermined intervals, a proximal end portion of each flow pipe is attached to the side wall of the first vertical main pipe so that the hot water can pass through the flow pipes from the first vertical main pipe to the second vertical main pipe, a leading end portion of each said flow pipe extends to the inside of the second vertical main pipe, the vicinity of the leading end portion of each flow pipe is bent upward so as to be parallel to the second vertical main pipe, and the leading end portion has a nozzle body, the second vertical main pipe has an opening at a lower end, and an upper side of the second vertical main pipe is horizontally bent to form a horizontal extension pipe near a top of the hot water storage tank, the first spiral drum is disposed in a vicinity of the middle of the horizontal extension pipe, the horizontal extension pipe is bent to connect to a vertical extension pipe at another side of the horizontal extension pipe, and an opening of the vertical extension pipe faces to the bottom of the hot water storage tank, the second spiral drum is disposed in a vicinity of the middle of the vertical extension pipe, wherein a last opening end of the vertical extension pipe is located in approximately the center in the vertical direction of the hot water storage tank, and the hot water suction pipe is vertically disposed at an approximately center line position in the vertical direction of the hot water storage tank, a lower end opening of the hot water suction pipe is located near the bottom of the hot water storage tank, an upper end portion of the hot water suction pipe extends into the inside of the horizontal extension pipe, and the upper end of the hot water suction pipe is bent so that a upper end opening of the hot water suction pipe is disposed in accordance with a hot water flow direction of the horizontal extension pipe.
