Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of constant temp gas water heater, comprises combustion chamber 1, heat exchanger 2, burner 3 and the cold water inlet 4 be connected with heat exchanger, hot water outlet pipe 5; Heat exchanger 2 is arranged on the top of combustion chamber 1, and burner 3 is arranged on the bottom in combustion chamber 1.
Also comprise main control unit 6, gas control valve 7, leaving water temperature sensors 8, flow of inlet water sensor 9, cold water inflow servomechanism 10, mixing cool water quantity servomechanism 11 and mixing cold water pipe 12,
Leaving water temperature sensors 8 is arranged on hot water outlet pipe 5, is successively set on cold water inlet 4 by cold water current direction cold water inflow servomechanism 10 and flow of inlet water sensor 9; Mixing cold water pipe 12 one end is communicated with the water inlet end of cold water inlet 4, the other end is communicated with the hot water outlet pipe 5 between leaving water temperature sensors 8 and heat exchanger 2;
Described main control unit 6 and gas control valve 7, leaving water temperature sensors 8, flow of inlet water sensor 9, cold water inflow servomechanism 10 and mix cool water quantity servomechanism 11 and be connected and connect;
When inflow temperature is too low or in the excessive situation of amount of inlet water, cold water inflow servomechanism 10 and gas control valve 7 work simultaneously; The normal operation of gas heater, mixing cool water quantity servomechanism 11 on mixing cold water pipe 12 shuts completely, and cold water water inlet servomechanism 10 is opened completely, and namely current only pass through cold water inlet, flow out through heat exchanger, hot water outlet pipe, cold water pipe 12 is anhydrous passes through in mixing; Temperature regulates the size by gas control valve 7 regulating gas, regulates the size of water temperature.Work as special circumstances, the situation as lower in inflow temperature in winter or user's hydraulic pressure is very large, under gas control valve 7 is adjusted to maximum case combustion gas, when hot water temperature can't reach user's request, master controller is just by regulating cold water water inlet servomechanism 10, reduce the water yield of main pipeline, until meet the design temperature of the user of user;
When inflow temperature is too high or in the too low situation of amount of inlet water, mixing cool water quantity servomechanism 11 and gas control valve 7 work simultaneously.
In the higher or situation that user's hydraulic pressure is lower of inflow temperature in summer, under gas control valve 7 is adjusted to minimum combustion gas, leaving water temperature is still excessively boiling hot, now master controller waits upon device 11 by regulating mixing cold water, make cold water pass through mixing cold water pipe 12 and enter hot water outlet pipe, with hot water mixing, until leaving water temperature is reduced to the set temperature of user.
Also comprise an inlet triplet for water pipe fitting 131 and outlet three way pipe fitting 132,
The straight tube of inlet triplet for water pipe fitting 131 is connected on cold water inlet 4, and the water side of straight tube is communicated with cold water inflow servomechanism 10;
The straight tube of outlet three way pipe fitting 132 is connected on the hot water outlet pipe 5 between leaving water temperature sensors 8 and heat exchanger 2, and described mixing cold water pipe 12 one end is connected with the arm of inlet triplet for water pipe fitting 131, the other end is connected with the arm of outlet three way pipe fitting 132.
Described master controller comprises single-chip microcomputer and function key; Described single-chip microcomputer and gas control valve, leaving water temperature sensors, flow of inlet water sensor, cold water inflow servomechanism and mix cool water quantity servomechanism and be connected and connect.
Described gas control valve 7 is electric gas control valve; Cold water inflow servomechanism 10 and mixing cool water quantity servomechanism 11 are electric water adjustable valve.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that for the person of ordinary skill of the art, when not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
