Description

Closed automatic control gas furnace

Technical field

The utility model relates to a kind of gas furnace, the closed automatic control gas furnace of particularly a kind of adjustable fuel gas amount and automatic control water temperature.

Background technology

Announcing name on October 6th, 2004, to be called " vertical sealing domestic gas heating stove " patent No. be 200320111925.0 patent application (this patent applicant and this case applicant are same applicants).Also there is perfect inadequately place in this patent application on structural design, for example, be not provided with gas regulating device, because the how much directly size of the control intensity of a fire of source of the gas, water temperature in the stove depends on the size of the intensity of a fire again so, therefore in use, owing to there is not gas regulating device, be easy to cause unnecessary waste, can not reach purpose of energy saving.In addition, this patent application does not have automaton, and promptly water temperature can not realize automatic control in the stove, therefore also requires further improvement on structural design.

Summary of the invention

In view of the deficiency that exists in the above-mentioned design, for reaching purpose of energy saving, the utility model provides a kind of can regulate the closed automatic control gas furnace that gas quantity can realize controlling automatically water temperature in the stove again.

This practical technical scheme of taking is: a kind of closed automatic control gas furnace, comprise shell, water jacket, heat-insulation layer, burner, combustion chamber, blower fan, heating outlet pipe, heating return pipe, it is characterized in that: also comprise Air-regulating valves, controller, control panel, water pump, high temperature inductive probe, low temperature inductive probe, isolate base plate, isolate base plate catch, gas inlet pipe, drainpipe, intensity of a fire peep hole, wherein, an end of gas inlet pipe is connected with Air-regulating valves by shell; The other end is connected with burner by the air admission hole of combustion chamber, and an end of heating water return pipe is welded on the bottom of water jacket; The other end stretches out from the back of shell after base plate is connected with the water pump of bottom of furnace body by isolating, and high temperature inductive probe and low temperature inductive probe are distinguished on cased the heating outlet pipe and heating return pipe; And be connected with controller respectively; Controller connects burner, blower fan, water pump and control panel respectively, isolates the spill that is shaped as of base plate catch; And be fixedly mounted on the bottom of combustion chamber, the minimum point place that isolates the base plate catch has apopore, and one of drainpipe terminates on the apopore; The other end is stretched out by shell, and intensity of a fire peep hole is opened the shell above burner and the front of combustion chamber.

Take the beneficial effect of the gas furnace generation of technique scheme to be: the size of how much controlling the intensity of a fire of adjustable fuel gas, to reach the purpose that reduces cost of use and energy savings.Simultaneously can control water temperature automatically.By the high and low temperature inductive probe, when leaving water temperature was higher than 90 ℃, burner cut out automatically, to prevent the water gasification.This moment, water pump was opened automatically, quickened the water circulation, and the low temperature backwater is sent into water jacket, and hot water is sent into radiator through hot duct in the water jacket.When return water temperature was lower than 20 ℃, burner was opened igniting automatically.In addition, isolate the base plate catch, but the condensed water that flows out in the splendid attire water jacket to prevent the control device humidity of bottom of furnace body, can also play the thermal source effect of heat radiation downwards of blocking simultaneously owing to be provided with spill in the bottom, combustion chamber.Therefore, the utility model also has advantages such as sealing is strong, the thermal efficiency is high, no flue dust discharges, safe and reliable.
