Document Type and Number:
WIPO Patent Application WO/2023/068465
Kind Code:
A1
Abstract:
The present invention relates to an instantaneous water heater corresponding to a water heater for sequentially heating water directly and indirectly to provide hot water while instantaneously heating the water to a required temperature, wherein the instantaneous water heater minimizes heat loss while enabling instantaneous hot water generation by increasing a heat exchange area. The present invention comprises: a body having a water introduction pipe through which raw water is introduced and a water discharge pipe through which hot water is discharged; a coil pipe connected to the water introduction pipe to allow the raw water to be introduced therethrough and having a lower pipeline for discharging the raw water introduced in the body; a heater for indirectly heating the water introduced in the coil pipe primarily and directly heating the water discharged from the body secondarily to generate hot water; and a steam module in which when the hot water is discharged, the steam of the hot water generated by the heater is introduced to discharge the hot water through the water discharge pipe while filling the steam pressure therein, and when the hot water is not discharged, the steam pressure is lowered.
