Drawings
Fig. 1 is a schematic structural diagram of a safety protection structure for a long open fire of a gas water heater in an embodiment of the utility model.
Detailed Description
The application scheme is further described below with reference to the accompanying drawings:
referring to fig. 1, the safety protection structure for the ever-open fire of the gas water heater comprises a shell 10, an air inlet pipe 11, a fire grate 12, a combustion chamber 13, a heat exchanger 14, a water inlet pipe 15, a water outlet pipe 16, an air exhaust device 17 and an ever-open fire device 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; the water outlet of the water inlet pipe 15 and the water inlet of the water outlet pipe 16 are respectively connected with the heat exchanger 14; the air exhaust device 17 is arranged in the shell 10 and is positioned above the heat exchanger 14; the ever-burning fire device 18 is arranged in the shell and is connected with the air inlet pipe 11 through a bypass air pipe.
When the gas water heater is used, gas is respectively conveyed to the fire grate 12 and the long open fire device 18 through the gas inlet pipe 11 and the bypass pipe, cold water enters the heat exchanger 14 through the water inlet pipe 15, the gas supplied to the fire grate 12 is combusted in the combustion chamber 13, heat is continuously transferred to the cold water in the heat exchanger 14, the cold water is changed into hot water, the hot water is conveyed to a water using end through the water outlet pipe 16, when the gas water heater works, the long open fire device 18 continuously works, namely the long open fire device 18 continuously burns, a small part of the gas which does not enter the combustion chamber 13 to overflow is ignited in the combustion process, and smoke generated by combustion is discharged out of the room under the action of the exhaust device 17.
Preferably, the outlet of inlet pipe 15 is higher than the inlet of outlet pipe 16. The water outlet of the water inlet pipe 15 is set to be higher than the water inlet of the water outlet pipe 16, so that the heated water in the heat exchanger 14 is discharged through the water outlet pipe 16, and the water supply temperature is ensured.
Preferably, the outlet of the inlet pipe 15 is connected to the top of the heat exchanger 14, and the inlet of the outlet pipe 16 is connected to the bottom of the heat exchanger 14. The delivery port department of inlet tube 15 is equipped with and slows down the flow box, and the box that slows down plays the current-limiting effect to the water that the delivery port department of inlet tube 15 flows into in heat exchanger 14, prevents that the too high cold water of pressure from rushing into in heat exchanger 14 violently, makes the water in heat exchanger 14 become cold to consume more gas and heat once more.
Specifically, the exhaust device 17 includes a motor 171 and an exhaust fan 172; the output end of the motor 171 is connected with the input end of the exhaust fan 172. The motor 171 drives the exhaust fan 172 to rotate, thereby exhausting the flue gas generated during combustion in the casing 10 through an exhaust pipe connected to the upper side of the casing 10.
Preferably, the exhaust device 17 further includes a smoke collection hood 173, and a smoke collection port of the smoke collection hood 173 faces the heat exchanger 14. The fume collecting hood 173 collects the fume to ensure that the fume generated during combustion is thoroughly discharged to the outside.
Preferably, the side wall of the heat exchanger 14 is provided with a thermostat 141. The temperature controller 141 monitors the water temperature in the heat exchanger 14, and when the water temperature reaches a predetermined temperature, the fire grate 12 stops heating or changes to a small fire, so as to achieve the purpose of saving fuel gas.
Preferably, a proportional valve 111 is provided on the intake pipe 11. The proportional valve 111 adjusts the output proportion of the fuel gas to save the fuel gas.
Preferably, the water inlet pipe 15 is provided with a water amount sensor 151. The water flow sensor 151 measures the inflow water flow, the controller of the gas water heater judges the water flow, and the current of the proportional valve 111 is adjusted, so that the gas flow is controlled through the proportional valve 111, and the phenomenon that the gas water heater is warm in summer and cool in winter in the using process is avoided.
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.
