<P>PROBLEM TO BE SOLVED: To provide a beverage dispenser preventing the lowering of the temperature of hot water in a high-temperature water layer zone stored in a hot water tank. <P>SOLUTION: This beverage dispenser is provided with: partition plates 72a and 72b for partitioning hot water stored in the hot water tank 70 into different-temperature layer zones; a temperature sensor 73a detecting the temperature of the hot water in the high-temperature water layer zone and outputting a temperature signal; a temperature sensor 73b detecting the temperature of the hot water in an intermediate-temperature water layer zone and outputting a temperature signal; a temperature sensor 73c detecting the temperature of the hot water in a low-temperature water layer zone and outputting a temperature signal; a heater 74, when the temperature signal output by the temperature sensor 73a for detecting the temperature of the hot water stored in the high-temperature water layer zone is lower than a prescribed lower limit temperature, heating it to a prescribed upper limit temperature by being energized by a signal output by a control part 95; a heat-insulation layer 75 reducing the amount of heat radiation from the outer wall face of a tank body 71; and a water supply opening 76 communicating with a water reservoir 10 by a hot water circuit 33 via water supply valve 32. <P>COPYRIGHT: (C)2008,JPO&INPIT |
