Embodiment
Below with reference to each embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are not
The limitation present invention, structure that one of ordinary skill in the art is made according to these embodiments, method or change functionally
Change and be all contained in protection scope of the present invention.
Domestic gas equipment, if gas heater and gas fired-boiler are all using fuel gas as fuel, such as natural gas, city
Coal gas, liquefied gas, biogas etc., by burning combustible gas come heat hot water to meet user's domestic water and/or central-heating
Demand.In following embodiments will by taking gas heater as an example come the present invention will be described, but the present invention can equally answer
For other domestic gas equipment such as gas fired-boiler.
With reference first to the gas-fired equipment in the first embodiment of the invention shown in Fig. 1 to Fig. 3 and the component of petticoat pipe annex
100.As shown in figure 3, in present embodiment, gas heater includes casing 11, is housed in burner 12 in casing 11, heat is handed over
Parallel operation 13, blower fan 14, the smoke exhaust pipe 15 for extending cabinet top and extend the water inlet pipe of the bottom of casing 11, outlet pipe and
Fuel gas transmission pipeline etc..
Casing 11 can be formed by some panel splicings, such as front panel 111, backboard 112, top plate 113, bottom plate 114, Yi Jiyi
To side plate 115.When equipment is installed on wall, its backboard generally offers air inlet to supply towards wall on backboard
Air needed for burning.Burner 12 includes burner shell, is usually provided with burner unit in it, if be such as arranged side by side
Dry fire row piece.The hybrid channel of air-gas can be provided with each fire row piece, the combustion gas that is conveyed by fuel gas transmission pipeline and
Primary air mixes in the hybrid channel and passes to the fire hole at the top of fire row piece to burn and generate hot cigarette
Gas.Due to fire row piece construction and be arranged as it is known to those skilled in the art that so applicant is no longer repeated herein.
For heat exchanger 13 in the top of burner 12, present embodiment, heat exchanger can use fin tube type heat
Exchanger, i.e., be provided with multiple fins in shell heat exchanger body, a heat-absorbing water pipe passes through these fins, its two difference round
Connected with water inlet pipe and outlet pipe.The combustion that air-gas mixture is formed after burner shell and heat exchanger shell splicing
Indoor Combustion is burnt, caused heat is absorbed by fin, and further passes to the water flowed through in heat-absorbing water pipe, the water after heating
The water pipe of domestic water is passed to by outlet pipe, so as to provide the user drink, the domestic water such as bathing.
Blower fan 14 is arranged on the top of heat exchanger 13, for promoting gaseous exchange, to provide the air needed for burning, and
