Drawings
Fig. 1 is a front view of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, an electric gas water heater comprises a gas burner 1, a heat exchanger 2, a fan unit 3, a cold water inlet pipe 4 and a hot water outlet pipe 5,
also comprises a main control board 6, an instant heating type electric heating device 7, a fuel gas proportional valve 8, a water flow sensor 9, an inlet water temperature probe 10 and an outlet water temperature probe 11,
the gas proportional valve 8 is communicated with the gas burner 1, the water flow sensor 9 and the water inlet temperature probe 10 are arranged on the cold water inlet pipe 4, and the water outlet temperature probe 11 is arranged on the hot water outlet pipe 5; the instant heating type electric heating device 7 is arranged on the cold water inlet pipe 4 between the inlet water temperature probe 10 and the heat exchanger 2;
the utility model discloses also can realize like this: the instant heating type electric heating device 7 is arranged on the cold water inlet pipe 4 between the inlet water temperature probe 10 and the heat exchanger 2, and the instant heating type electric heating device 7 is also arranged on the hot water outlet pipe 5 between the outlet water temperature probe 11 and the heat exchanger 2;
in winter, the instant electric heating device 7 compensates the temperature of the hot water generated by the heat exchanger 2, and the instant electric heating device 7 is used as an auxiliary to solve the problems of high gas consumption and low hot water outlet temperature; in summer, the instant heating type electric heating device 7 works.
The instantaneous electric heating device is a resistance heating type, a high-frequency heating type, an electromagnetic and microwave heating type, an electrode heating type, a ceramic heating type or a surface coating heating type. The power of the instant heating type electric heating device is smaller than that of an electric heating body of the water storage electric water heater, and the instant heating type electric heating device can be directly connected with commercial power, so that the electric water heater is safe in electricity utilization.
As a further improvement of the utility model: also included is an electrically heated water storage tank 12,
the water storage tank 12 is arranged at the water outlet end of the hot water outlet pipe 5; the problem of the water suddenly cool and suddenly hot when shutting down and using again is solved.
After the water outlet temperature is set: the method comprises the following steps of water inlet, outputting a signal by a water flow sensor, outputting a signal by a water inlet temperature probe, calculating total heat load required by main control, starting heating of an electric heating module, starting a fan, igniting the main controller, stopping the fan, opening a proportional valve, detecting the ignition of a burner by the main controller, starting the fan, outputting a water outlet probe signal, and adjusting the power output of the electric heating module and the burner by the main controller to meet the condition that the water outlet temperature is consistent with the set water outlet temperature;
secondly, in a hybrid mode, after the water outlet temperature is set, water inlet, the output signal of a water flow sensor, the output signal of a water inlet temperature probe, the total load required by main control calculation, the work of a gas burner, and the fixed power heating compensation fixed temperature of an electric heating module;
thirdly), pure electric heating; the electric heating module can work immediately after a water flow signal exists, the heating is faster than that of a gas water heater, the waiting time is shorter, time and water are saved, and the user experience is better;
what has been described above is only a preferred embodiment of the present invention. It should be noted that, for a person skilled in the art, several modifications and variations can be made without departing from the principle of the invention, which is also considered as the protection scope of the invention.
