Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

referring to fig. 1, the anti-freezing structure of the gas water heater of the present application includes a housing 10, an air inlet pipe 11, a fire grate 12, a combustion chamber 13, a heat exchanger 14, an inlet pipe 15, a coil pipe 16, an outlet pipe 17 and an exhaust fan 18; one end of the air inlet pipe 11 penetrates through the shell 10 and is connected with a fire grate 12 arranged in the shell 10; the combustion chamber 13 is covered with a fire grate 12; the heat exchanger 14 is arranged in the shell 10 and is positioned above the combustion chamber 13; one end of the coil pipe 16 is connected with the water outlet of the water inlet pipe 15, and the other end of the coil pipe 16 is connected with the water inlet of the heat exchanger 14; the water outlet pipe 17 is connected with the water outlet of the heat exchanger 14; the exhaust fan 18 is arranged in the shell 10 and is positioned above the heat exchanger 14; wherein, the outer side wall of the coil pipe 16 is wrapped with an electric heating film 19. When the electric heating film is used specifically, the electric heating film 19 is electrified to generate heat to be transmitted to the coil pipe 16, so that water in the coil pipe 16 cannot be frozen under the influence of low ambient temperature, and the normal use of the gas water heater is ensured.

Preferably, the side wall of the coil 16 is provided with a temperature sensor 20, and the temperature sensor 20 is electrically connected to the electric heating film 19. The temperature sensor 20 monitors the temperature of water in the coil pipe 16, and when the temperature of the water is lower than a preset value, the electric heating film 19 is electrified to generate heat and transmit the heat to the coil pipe 16, so that the water in the coil pipe 16 is prevented from being frozen.

Preferably, the outer side wall of the water inlet pipe 15 is also wrapped with the electric heating film 19. The electric heating film 19 plays a preheating role for the water in the water inlet pipe 15, so that the temperature of the water entering the heat exchanger 14 is higher than that of the cold water, the time of boiling the water to the preset temperature is shortened, and the fuel gas is saved.

Preferably, the anti-freezing structure of the gas water heater further comprises a smoke collecting hood 21; the fume collecting hood 21 has a fume collecting port facing the heat exchanger 14 and a fume discharge port facing the exhaust fan 18. The smoke collecting hood 21 collects smoke generated in the combustion process, and ensures that the smoke is thoroughly discharged outdoors.

In one or more embodiments, a proportional valve 22 is provided on the intake pipe 11. The proportional valve 22 adjusts the output proportion of the gas to save the gas.

In one or more embodiments, water level sensor 23 is provided on inlet pipe 15. The water flow sensor 23 measures the inflow water flow, the controller of the gas water heater judges the water flow, and the current of the proportional valve 22 is adjusted, so that the gas flow is controlled through the proportional valve 22, and the phenomenon that the gas water heater is warm in summer and cool in winter is avoided in the using process.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
