To always supply the sufficient quantity of drink by providing a supply pipe for supplying drink to a vessel, an opening and closing valve provided in the supply pipe and a control means for deciding a water level in the vessel based on a sensing signal supplied from a water level sensing means.

When a vessel 50 is inserted into a drink vessel housing chamber 30, the inlet pipe 52 of the drink vessel is connected to a connecting part 32a under the pressure thereof. When the pipe is completely connected to the connecting part, a lead armature 37 is closed by a permanent magnet 54 to inform a control part that the vessel 50 is located at a prescribed position. Then, after the control part recognizes whether the vessel 50 is provided at the prescribed position, it opens a solenoid valve 34 to supply city water to the vessel 50. A water level sensor 36 senses the water level at prescribed time intervals and provides it to the control part. The control part decides the water level in the vessel 50 based on a signal from the water level sensor 36, and closes the solenoid valve 34 to stop the supply of the city water when the water level reaches a reference water level.
