PURPOSE:To drop a temperature of drip hot water dispersed by a hot water dispersing means to a temperature being suitable for generating a drink, and to improve the quality of a drip drink by staring in advance drink hot water from a boiler means in a hot water storage tank, and also, opening vapor pressure in the hot water storage tank. CONSTITUTION:When a first control means 8 sets a hot water pressure feed means and an opening means to an operating state, a temperature of drink hot water in a boiler 1b required for dropping properly a temperature of drip hot water stored in a hot water storage tank 4 to a value being suitable for generating a drink can be secured in advance. Also, in the case a second control means 9 executes the control so that a high pressure vapor pressure feed means 7 is set intermittently to an operating state, power of drip hot water dispersed into a drip container 3a from a hot water dispersing means 2 becomes strong under an intermittent high pressure vapor pressure feed by the high pressure vapor pressure feed means 7, becomes weak under an intermittent high pressure vapor pressure feed stop by the high pressure vapor pressure feed means 7, and dispersion of drip hot water into the drip container 3a from the hot water dispersing means 2 is executed uniformly to a raw material in the drip container 3a in accordance with a variation of its power, therefore, the quality of a drink can be equalized. |
