Water inlet pipe 1-2, outlet pipe 1-3 on 1-1；It is characterized in that, being equipped with connection between the water inlet pipe 1-2 and outlet pipe 1-3
Pipe 3 is equipped with unidirectional stop valve 4, between tie point A, C and heat exchanger 1-1 of the communicating pipe 3 on the communicating pipe 3
Pipeline is equipped with circulating pump 5 and water flow sensor 6, and the tie point is the company of communicating pipe 3 and water inlet pipe 1-2, outlet pipe 1-3
Contact, the unidirectional stop valve have the function of water flow from outlet pipe 1-3 to the one-way conduction of water inlet pipe 1-2 and water flow cut-off function
Energy.
Wherein, the gas heater ontology 1 includes shell, the heat exchanger, the water inlet pipe, the outlet pipe, institute
It states communicating pipe and the unidirectional stop valve is all located in the shell.
The hot water circulating pipeline 2 by be supplied water with water spot 7 hot-water line 2-1 and cold water pipe 2-2 be formed by connecting, described
It is connected with check valve 8 between hot-water line 2-1 and the cold water pipe 2-2, leads water flow unidirectionally from hot-water line 2-1 to cold water pipe 2-2
It is logical.
The unidirectional stop valve 4 uses electronic cut-off check valve.
The circulating pump 5 uses variable-ratio water pump.
As shown in Fig. 2, in actual work, by changing 5 revolving speed control loop water flow of circulating pump, and then controlling combustion gas heat
Hydrophone ontology 1 whether ignition operation.In preheating heating process, 5 high speed operation of circulating pump will add in circulating chilled water to heat exchanger
Heat forms systemic circulation circuit A-B-C-D-A, is after the completion hot water in hot-water line 8 and cold water pipe 9.
The shower of user's first time boiled water is completed, Guan Shuihou, and the master controller in gas heater ontology 1 sends instruction, is opened
Dynamic circulating pump 5, while electronic cut-off check valve is opened, and the lesser circulation loop A-B-C-A of resistance is formed, and controls water pump low speed
It operates 20s (time can be adjusted according to gas heater specification, type), makes circulating water flow lower than gas heater
Initiation value, gas heater misfire, and circulating pump 5 pushes the cold water being detained in water inlet pipe 1-2 to outlet pipe 1-3, in the process
In, cold water can fully absorb the waste heat in heat exchanger 1-1 and be heated, while in the A-B-C-A of partial circulating circuit, cold water

Being each filled with warm water or hot water, (mixed water temperature is mainly influenced by the temperature difference between inflow temperature and the leaving water temperature of setting, temperature
Difference is small, then mixed water temperature is high, otherwise mixed water temperature is lower).
When the secondary boiled water of user is in use, in gas water heater ignition heating process, flowing through heat exchanger is warm water, when
When the cold water of main pipe rail enters gas heater, cold water can be heated to be the heat of set temperature by gas heater immediately
Water can be effectively relieved using this method in no configuration temperature buffer container, cold wave water problems caused by secondary booting, greatly
It is big to promote bath comfort.
If user has boiled water bathing movement in circulating pump low speed operational process, water flow will be increased rapidly, reach combustion
Gas Water heater igniting burning condition, ignition operation, circulating pump 5 stop gas heater immediately immediately, while electronic cut-off is unidirectional
Valve is closed immediately, and gas heater enters conventional bathing working condition, guarantees the just common water of user.
