This article is in view of the existing water dispensers’ repeated heating, large energy consumption and fresh water quality’s problem, designed a new type energy saving water dispenser with the function of rapid cooling-or-heating. Anhydrous bravery structure is used in the water dispensers in drinking water flow process to cool or heat it, so as to ensure the water quality fresh. Among them, the application of semiconductor refrigeration technology achieved collecting heat and preheating the water [1], which is called the initial heating. Cooperating with the secondary heating of the electrothermal quartz heating tube, the water dispensers really realize the flowing liquid heating, bid farewell to the so-called thousand-times boiling water and improve the heat energy utilization greatly [2].
