Abstract
The invention relates to a low-noise gas instantaneous water heater, belonging to the technical field of gas appliances. The low-noise gas instantaneous water heater comprises a combustion device, a heat exchanger and a blower; wherein the combustion device, the heat exchanger and the blower are arranged such that a combustion flue gas is discharged after passing sequentially through the heat exchanger and the blower; the blower comprises a stepless speed regulating motor with a motor control panel and an impeller driven by the motor, and at least one thermal insulation device is arranged between the motor control panel and the combustion flue gas generated by the combustion device. The low-noise gas instantaneous water heater is capable of combining the advantages of an updraught structure and a stepless speed regulating blower, effectively solving the problem of loud noise in the operation process of the heater, and reaching the requirements of the constant temperature performance, exhaust gas indexes and reliability of the gas instantaneous water heater.
