PURPOSE: To efficiently elute minerals from a chemical stone in a mineral water producing device for eluting an eluting component into a liq. from the stone by rotating a cartridge contg. the crushed chemical stone by a rotating mechanism contained in a lid.

CONSTITUTION: This chemical stone-rotated water generator is filled with water to a level 20, a motor 4 is driven by turning a control knob 9 of a timer, and hence a cartridge 12 contg. the crushed chemical stone is rotated by the power of a battery 10 through a decelerating mechanism 5 for the time set by the timer. The water in the cartridge 12 is centrifugally discharged outward by the rotation, the water sucked from the lower part of an inner cylinder 18 is sent upward in the inner cylinder 18 and introduced into a chemical stone chamber through a small hole provided in the inner cylinder 18, and the water in the chemical stone chamber is passed through a small hole furnished in an outer cylinder 19 and discharged outward. All the water in the generator is passed through the surface of the stone and circulated, and a high elution effect is exhibited.
