A gas water heater with constant water outlet temperature

Abstract

The invention discloses a gas water heater with contestant-temperature outlet water. The gas water heater comprises a heating device, a water inlet pipe and a water outlet pipe, the water outlet pipeis provided with a first connecting pipe and a second connecting pipe, one ends of the first connecting pipe and the second connecting pipe are connected to the water outlet pipe, and the other ends of the first connecting pipe and the second connecting pipe are gathered to the water outlet pipe; a first front bypass pipe and a first back bypass pipe are arranged between the water inlet pipe and the first connecting pipe, a second front bypass pipe and a second back bypass pipe are arranged between the water inlet pipe and the second connecting pipe, one ends of the first front bypass pipe andthe second front bypass pipe are connected to the first connecting pipe and the second connecting pipe correspondingly, and the other ends of the first front bypass pipe and the second front bypass pipe are connected to the water inlet pipe; and one ends of the first back bypass pipe and the second back bypass pipe are connected to the first connecting pipe and the second connecting pipe correspondingly, and the other ends of the first back bypass pipe and the second back bypass pipe are connected to the water inlet pipe. According to the gas water heater, after a hot water valve is opened, hot water conveying can be kept all the time, the cold water sudden striking phenomenon is avoided, and the bathing comfort is greatly improved.

Description

technical field [0001] The invention relates to a heater, in particular to a gas water heater with constant temperature outlet water. Background technique [0002] A gas water heater, also known as a gas water heater, refers to a gas appliance that uses gas as a fuel to transfer heat to cold water flowing through a heat exchanger through combustion and heating to achieve the purpose of preparing hot water. Generally, the working principle of a gas water heater is that the hot water valve is opened, and cold water enters the water heater from the water inlet pipe; among them, after the cold water enters the water heater, it flows through the water-gas valve body, and under the action of the pressure difference of the water flow, the water-gas valve is pushed, and At the same time, push the micro switch of the DC power supply to turn on the power and start the pulse igniter. At the same time, open the gas transmission electromagnetic valve, and continue to automatically re-ign...
