The specific embodiment

As Fig. 1-4, forced air inlet balanced type fuel gas heating apparatus of the present utility model, it comprises that the movement two large divisions of shell and Qi Nei forms.

Shell mainly comprises top panel 17, lower panel 28, a left side, right plate 16,13, base plate 14 and blinds 29, on, lower panel 17,28 by draw-in groove connect together the back be connected with base plate 14 both sides, a left side, right plate 16,13 are connected, lower panel 17,28 and the both sides of base plate 14, and blinds 29 is installed in the rectangular frame on the lower panel 28, can be by regulating the angle of blinds 29, regulate the hot-blast outlet direction, gauge tap 20 (comprising gas circuit and circuit) and igniter 19 and main valve 25 are installed in the control box 21 on the top panel 17, install one on the control box 21 and renovate 18, as shown in Figure 3.

Movement mainly comprises combustor mechanism, as Fig. 2, shown in 3, burner removes into, gas outlet and chimney 12 are with outside the external world communicates, it is a complete airtight metal burning box, this burner box is a cavity of being made up of outer cover 1 and back plate 5, the exhanst gas outlet at its rear portion links to each other with the air inlet of flue interlayer 6, the right-hand member of flue interlayer 6 links to each other with air intake box 11, the right-hand member of flue interlayer 6 penetrates and is installed in the air channel interlayer 7, its port rear wall direction of giving vent to anger towards air channel interlayer 7, in chimney 12 has, two-layer outward, its skin passes base plate 14 backs and links to each other with air channel interlayer 7, its internal layer passes air channel interlayer 7 rear walls and links to each other with the outlet of giving vent to anger of flue interlayer 6, the lower end of air channel interlayer 7 links to each other with air intake box 11 upper ends, the other end of air intake box 11 links to each other with the right-hand member of burner box, and forced air inlet device 10 is contained in the closed cavity of air intake box 11 and burner box right-hand member formation.Burner box inside is provided with a stainless steel combustion barrel 3 and flame-out protection device 4 by support, and burner outer cover 1 surface is with fin 2, and fuel gas pipeline 8 and nozzle 9 pass burner box by joint and encapsulant, and its nozzle 9 is aimed at combustion barrel 3.Be provided with forced air inlet device 10 at the burner end face; it mainly is made of a fan; it will sucking in the burner from outdoor air through air inlet; the air that a part has a certain flow rate enters the combustion gas that combustion barrel 3 end caps are forced and nozzle 9 sprays and fully mixes after-combustion (mixed once); portion of air directly enters burner cavity and provides oxygen for the ever-burning flame of flame-out protection device 4 and the secondary mixing combination burning of combustion barrel 3 in addition; when burner internal combustion flame undesired; such as flame-out; anoxic; when abnormalities such as flame; flame-out protection device 4 action rapidly cuts off all sources of the gas; circuit in forced air inlet device 10 breaks down; warmer can cut off gas circuit automatically; have only when circuit is under the closed circuit state main valve 25 and just can open, complete machine could move.Cylinder blower fan 15 flexibilities of burner bottom are fixed on the base plate 14 of shell (reducing vibrating noise), its air inlet is opened the long lumbar hole at close base plate 14 places below, its air outlet is positioned at the upper end of cylinder blower fan 15 facing to burner, by force burner heat is carried out heat exchange, thereby make indoor air circulation heating improve heating effect greatly.

The course of work of the present utility model is as follows; at first source of the gas is inserted pressure-reducing valve 24; guarantee to open two gauge taps 20 after errorless; this moment, the motor to stream roller blower fan 15 and forced air inlet device 10 brought into operation; the turn-knob 22 of pressing main valve 25 is (if electrical appliance part fails normally to move; main valve 25 akinesias this moment; be that gas circuit can not conducting); wait for after 3-5 minute; combustion gas is by main valve 25 and each fuel gas pipeline 26; 8; 23 drain the residual air in the pipeline; press igniter 19 (piezoelectric ceramics or pulsed ignition switch); can light this moment by the ever-burning flame of the discovery of the peep hole on the burner outer cover 1 flame-out protection device 4; then open main valve 25 fully; combustion barrel 3 is started working; if in the middle of operation, burning occurs such as flame-out; anoxic; when abnormalities such as flame, whole source of the gas is cut off in 4 actions of safety shutdown protective device automatically.

In this practical heating process as shown in Figure 1, 2; outdoor fresh air enters air channel interlayer 7 laggard inlet air boxes 11; enter burner through fan 10; a part enters combustion barrel 3 burnings with combustion gas mixing; a part directly enters burner cavity in addition provides the oxygen of flame-out protection device 4 ever-burning flames burning and the secondary of combustion barrel 3 to mix required oxygen, and waste gas is directly discharged outdoor by flue interlayer 6 and chimney 12 again.

What be installed in the burner below forcibly makes indoor cold air suck from outer casing bottom to stream roller blower fan 15, fin 2 by burner surface, the convection current of heat by air that accumulates in like this on the burner comes out from the blinds 29 of shell, realizes that so far heat hands over the exchange overall process.
