Abstract
The invention discloses a constant-temperature gas water heater. The constant-temperature gas water heater comprises a single-chip microcomputer, an electromagnetic valve, a gas proportional valve, a cold water inlet temperature sensor, a hot water outlet temperature sensor, an operation panel and a gas distribution rod. According to a first working mode, the control panel is operated to select a low-temperature section; the single-chip microcomputer outputs a first current signal to control the opening degree of the gas proportional valve; the temperature in the temperature range of the low-temperature section is selected; and the selected hot water outlet temperature is kept constant. According to a second working mode, when the control panel is operated to select a high-temperature section, the single-chip microcomputer outputs a second current signal to control the opening degree of the gas proportional valve, the temperature in the range of the high-temperature section is selected, and the selected hot water outlet temperature is kept constant. Defects in the prior art are overcome, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of gas heater, especially a kind of constant temp gas water heater.
