Description

A kind of gas heater of adjustable primary air amount
Technical field
The utility model is related to gas instantaneous water heater technical field, the combustion of primary air when being burnt more particularly, to regulation Gas technical field of water heaters.
Background technology
It is divided into primary air and auxiliary air using the air required for the gas heater of atmospheric burner.Different Load, different gas kind is also different to an auxiliary air ratio requirement, and the ejector capacity of primary air is influenceed by nozzle, is changed Become little, existing technology is to adjust the injection energy of primary air by increasing primary air baffle plate or auxiliary air baffle plate Power, it is impossible to flexibly change according to the different use states of water heater.Patent name is a kind of burner for gas water-heater (CN201120090070.2), openly (announce) number be CN201992648U, the applying date be 2011.03.31 it include burner Component, the burner assembly includes burner and airway tube of some tools with multiple burning fire holes;Also include an air to distribute There is gap between device, two distribution plates of air distribution device;Tubular of the upper end of the burner from air distribution device The bottom insertion of base, the gap through two distribution plates, burner lower end are located at below distribution plate, distribution plate and burning Device side is fitted, and auxiliary air hole coordinates with burning fire hole, and burner combustion fire hole is located in base.It is also using baffle plate come Regulation is realized, there is also above mentioned problem.
Utility model content
The purpose of this utility model, which provides proposition one kind aiming at the deficiencies in the prior art, can adjust primary air Amount, the effective ejector capacity for improving primary air, more reasonably according to gentle kind of flexible modulation primary air system of different load Number, improves the gas heater of the adjustable primary air amount of loom performance.
In order to reach object above, the utility model patent is adopted the following technical scheme that:
A kind of gas heater of adjustable primary air amount, including heat exchanger, burner, inlet and outlet pipe, combustion gas Air exhauster is provided with water heater master controller and exhanst gas outlet, exhanst gas outlet passage, the burner connects gas inlet pipe It is provided with road and primary air import, gas inlet pipeline in gas ratio valve, primary air inlet ductwork and is provided with air blast Machine, it is characterised in that the gas nozzle on the gas inlet pipeline is set with the air outlet slit in primary air inlet ductwork On same axis.
As a further illustration of the above scheme, the air blower in the primary air inlet ductwork rouses for small-sized adjustable speed Blower fan, it couples with gas heater master controller, and the quantity delivered of such air can freely be adjusted according to payload.
Further, the end of the primary air inlet ductwork is provided with square tube component, and gas inlet pipeline passes through side Tube assembly, its gas nozzle stretches out from the air outlet slit end on air intlet pipeline, and air outlet slit is included in around gas nozzle.
Further, the square tube component, which is gone into battle, shows multiple air outlet slit ends, contains in each air outlet slit end There is gas nozzle, shunt and go out from gas inlet pipeline.
Compared with prior art, the gas and hot water utensil for a kind of adjustable primary air amount that the utility model patent is provided There is following beneficial effect:
Air outlet slit and gas nozzle are arranged on same axis using the utility model of said structure, one can be with Enter burner in air and combustion gas;Two can keep combustion gas runner constant;Three can pass through the air of ejection in underload Volume inhales surrounding air increase primary air ratio;The effective ejector capacity for improving primary air, more reasonably according to different negative Gentle kind of air stoichiometry of flexible modulation one or two of lotus, while can increase the adaptive capacity to environment of burner, improves overall performance.
