Claim:
1. A water recovery device to recover water from exhaust gas including water vapor, comprising: an exhaust gas pipe that is connected to a combustion device which combusts fuel to emit exhaust gas including water vapor, and that defines an exhaust path of exhaust gas emitted from the combustion device; a water generation unit that generates water by cooling exhaust gas in the exhaust gas pipe to condense water vapor in the exhaust gas; and a water container that is disposed on the exhaust path and stores water generated by the water generation unit, wherein the water generation unit includes: an acoustic-wave generator that generates acoustic waves by absorbing heat from the exhaust gas pipe and giving the heat to working fluid, which transmits acoustic waves by oscillating, to cause the working fluid to oscillate; a transmission pipe that is internally filled with the working fluid and transmits acoustic waves generated by the acoustic-wave generator via oscillations of the working fluid; and a cold-heat generator that generates cold heat to supply the cold heat to the exhaust gas pipe by receiving acoustic waves transmitted through the transmission pipe and giving heat to the acoustic waves.
