Combined gas heating hot water furnace, suitable for residential communities, hotels, office buildings, hospitals, schools and other enterprises and institutions. Furnace body The furnace body is provided with a water collecting pipe, a temperature detection probe is arranged above the water collecting pipe, and a water inlet branch pipe and an outlet branch pipe are arranged below, and a heating unit is arranged between the two pipes, and a collecting pipe is arranged at the bottom of the furnace. Supply gas to the heating unit. Pulse ignition, water and gas induction linkage, built-in controller to control ignition, combustion, heating water temperature, water pump start and stop. And the heating hot water stove has water shortage protection, anti-overheating protection, accidental flame out protection and other functions.

The furnace body has a collection pipe, inlet branch pipe, outlet branch pipe, circulating water pump, isolating water valve, collecting pipe, gas branch pipe, isolating gas valve, solenoid valve. Combustion first, its structural characteristics are: stove below the collecting pipe, the collecting pipe on the collecting pipe branch, the stove above the collecting pipe, the water inlet branch pipe and the water outlet branch pipe below the collecting pipe. There is a heating unit in parallel between the roads. The heating unit is composed of water passage, air passage and combustion chamber. The inlet branch is connected with the circulating water pump through the isolation water valve, and the circulating water pump is connected with the water diversion device, and the water diversion device is connected with the heat exchanger. The heat exchanger is connected to the water branch by isolating the water valve. The combustion chamber is located below the heat exchanger. The lower part of the combustion chamber is provided with a combustion head, the combustion head is provided with a pulse ignition needle and ignition needle, and the bottom is provided with a solenoid valve.

Temperature control: detected by the water temperature detection probe, namely the thermistor Pt in the temperature control circuit. The thermistor Pt is connected to the comparator port of 555 integrated circuit, the end is connected to the adjustable potentiometer for temperature setting, and the end is output. When the detected temperature is higher than or equal to the set temperature, the output of the terminal is 0. The signal controls the small relays of the three pumps. One of the signals directly controls the relay through the switching tube, causing the power failure.

The pump stops working, the air valve closes, the flame goes out, and the heating stops. A signal of the hot water heater through the switch tube composed of 20 seconds delay circuit, control relay to make it power off, the pump stops working. A signal passes through a 40-second delay circuit of switching tubes that controls the relay and disables it, stopping the pump. If the detected temperature is lower than the set temperature, the terminal output "1", relay action at the same time, start the water pump.

The control part of the hot water heater adopts the microcomputer control technology to control the ignition, combustion, heating water temperature and the start and stop of the water pump. Temperature control: water temperature detection probe, that is, the thermistor in the temperature control circuit, the hot water heater will detect the temperature signal transmitted to the controller, the controller completes the temperature control.
