PURPOSE:To automate the supply of water by controlling the quantity of the water for a water injection valve, which is provided in an water injection port directly connected to a water pipe, and an extracting valve for the raw materials of drink. CONSTITUTION:A water pouring port 14, which is provided on the back of an enclosure 1, is directly connected with the water pipe and a water injection valve 16 is provided to control the quantity of the water in an interval to a water pouring pipe 15 opened in the bottom part of a hot water tank 6. For a drink raw material bottle 21 inserted into a drink raw material cooling tank 11, when the tip of the bottle 21 is inserted into an extracting valve 22, a liquid seal is opened and the extracting valve 22 opens the valve by electric operation and extracts the raw materials of the drink. A mixing nozzle 23 mixes the hot water, which is supplied from a hot water supply port 18, with the raw materials of the drink. When an extraction switch 5 is operated, the extracting valve 22 is operated for fixed time by an output from a control circuit 24 and the fixed quantity of the drink raw materials is extracted. Simultaneously the water injection valve 16 is operated for fixed time and the fixed quantity of the water is poured into a hot water tank 6. Then, the hot water in the hot water tank 6 is poured through from a hot water supply port 18 through a hot water supply pipe 17. The raw materials of the drink is mixed with the hot water and supplied from the mixing nozzle 23. |
