DISTILLATION TYPE WATER DRINKING DEVICE AND ENERGY-SAVING HEATING UNIT THEREOF

摘要

A distillation type water drinking device includes a liquid supply unit(12), a heat exchange tube(2), a hot water tank(4), a steam pipeline (5), a condensing unit (6), a liquid collector (7) and a water outlet valve(8). One end (21) of said heat exchange tube (2) is connected with said liquid supply unit (12), while the other end (22) is communicated with said hot water tank (4). One end (51) of said steam pipeline (5) is communicated with said hot water tank, while the other end (52) is communicated with said condensing unit (6), and said steam pipeline(5) partly gets through the heat exchange tube (2). The end of said condensing unit (6) which isn't communicated with the steam pipeline is communicated with the liquid collector (7). Said water outlet valve (8) is communicated with the liquid collector (7) by a water outlet pipeline (T2). Since the steam pipeline (5) partly gets through the heat exchange space (23), the liquid in the heat exchange tube can be preheated by the temperature of the steam in the steam pipeline (5), and the temperature of the steam is decreased, which can reduce the power consumption.
