<p>A water treatment device (220) heats raw water and vaporizes a portion thereof in an evaporation part (34), and condenses the vaporized steam in a condensation area (240) to obtain condensed water. The water treatment device (220) is provided with: a heater (32) for heating the raw water; steam guiding parts (35, 36) for guiding, towards the condensation area (240), steam vaporized from the raw water heated by the heater (32); and a pipe (221) in which circulating water is guided from the condensation area (240) to the evaporation part (34), heat exchange between the circulating water and the steam guided to the condensation area (240) by the steam guiding parts (35, 36) is induced, and heat exchange between the circulating water and the raw water in the evaporation part (34) is induced.</p> |
