PURPOSE: A heater tank structure of an automatic vending machine is provided to have a small size by supplying a hot water after instantly heating water under high temperature and high pressure. CONSTITUTION: The heater tank structure of an automatic vending machine comprises a control unit(20), a hot water containing unit(23), a heater(24), a heat absorption pipe(25), an electronic valve(26), a temperature sensor(27), and a pressure sensor(28). The hot water containing unit(23) has an input(23a) and an outlet(23b) for circulate water, with the electronic valve(26) for an opening and closing of a water route installed with the input(23a) and the outlet(23b). The heater(24) generates a heat so that the interior of the unit(23) becomes a state of a high temperature. The heat absorption pipe(25) are connected to both the input(23a) and the outlet(23b) so as to be run to each other. The control unit(20) performs functions that a hot water is generated adjusting an output of the heater(24) according to inputs from the temperature sensor and the pressure sensor, and that a generated hot water is outputted generating an output to the electronic valve(26) according to an outlet signal of a drink. |
