CN2330903Y - Direct ignition device for stove using liquid fuel - Google Patents

Abstract

The utility model provides a direct ignition device for a stove using liquid fuel, comprising a porous infrared ignition ring arranged at the bottom of the wind bowl of a stove end. The ignition ring is arranged on the wind bowl through a fixed ring. Two ignition electrodes are arranged in the ignition ring. The ignition electrodes are connected with an ignition transformer. The structure is simple, and the operation is safe.

Description

Stove and accessory uses the liquid fuel direct fire unit

The utility model relates to a kind of stove and accessory of combustion of liquid fuel.

With liquid fuels such as diesel oil is the stove and accessory of fuel, all comprises the burner of being made up of parts such as cartridge, branch food tray, combustion-supporting cap, wind bowl and overcoats.In order to light liquid fuel, be provided with the alternating current arc ignition mechanism in the burner that has.Its complex structure is prone to fault, and electric shock accidents easily takes place in the ac high-voltage igniting.And most stove and accessorys are to adopt the fiber cotton yarn of oil-impregnated is lighted earlier, remove to light burner again with it then, and residue influences environmental sanitation on every side during not only complicated operation, and prefiring outside wind goes out burner.

The purpose of the utility model is to provide stove and accessory a kind of simple in structure, safe in utilization to use the liquid fuel direct fire unit.

The purpose of this utility model is achieved in that it comprises the porous infrared ray ignition ring of the wind bowl bottom that is installed on burner, ignition ring is installed on the wind bowl by a retainer plate, two fulcrum thermoelectricity plates are installed in the ignition ring, and ignitor links to each other with ignition transformer.

The advantage of the utility model is: form 1.5 ten thousand volts of direct currents by ignition transformer between two electrodes, direct current punctures air and form the loop between retainer plate and wind bowl, this moment, high-temperature electric arc radially both sides was successively lighted the multiple holes infrared ray ignition ring of oil-impregnated from circumference, flame is drawn close mutually, form a pyrosphere at last, reach the purpose of preheating, fire fuel oil.It has safe and reliable, and the ignition success rate height is not fragile, long service life, multiple advantages such as cost is low.

Fig. 1 is the vertical view of burner of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is a circuit diagram of the present utility model.

For example the utility model is done more detailed description below in conjunction with accompanying drawing: in conjunction with Fig. 1 and Fig. 2.Form burner by parts such as overcoat 11, cartridge 1, wind bowl 3, branch food trays 2.Be surrounded by retainer plate 4 outside the porous infrared ray ignition ring 5, they are installed on the wind bowl bottom.The two fulcrum thermoelectricity utmost points 7 are installed in the ignition coil, and ignitor links to each other with ignition transformer 8.Have a spout hole on the ignition ring at least, limit for height overflow pipe 6 is installed in the spout hole, the limit for height overflow pipe links to each other with auxiliary fuel tank.The use of device of the present utility model is described below in conjunction with Fig. 1, Fig. 2 and Fig. 3.For stove and accessory when using liquid fuel, fuel is transported to cartridge 1 through constant displacement pump in the auxiliary fuel tank, flows to the bottom surface of wind bowl 3 through minute food tray 2, the oilhole through retainer plate 4 bottom surfaces soaks the infrared ray ignition ring 5 in the retainer plate.As in case operator's maloperation excess fuel feeding occurs, influence ignition ring and lights, unnecessary oil flows back to auxiliary fuel tank through 6 dischargings of liquid level limit for height overflow pipe, but at this moment stove and accessory to be in fired state.Ignition order: it is bright that stacked switch K1 is screwed into priming supply side 1-1 ignition light HG1, show that time relay KT is to connect, ignition transformer 8 is to start working, this moment the two fulcrum thermoelectricity utmost points 7 between to form 1.5 ten thousand volts of direct currents, direct current punctures air and forms the loop through retainer plate 4 and wind bowl 3, this moment, high-temperature electric arc was radially successively lighting both sides from circular shaft with the porous infrared ray ignition ring 5 of oil-impregnated, flame is drawn close pyrosphere of last formation mutually, after the preheating 30 seconds, K1 is screwed into the fan power side, interlocking cut-out point firearm, this moment, magnetic valve YV closed cut-out, the discharge-channel of overflow pipe 6, guarantee the normal combustion fuel feeding, fan starting, beginning air feed, the operator opens fuel tap and supplies with burning oil, and whole operation finishes.

Claims (2)

1, a kind of stove and accessory uses the liquid fuel direct fire unit, it is characterized in that: it comprises the porous infrared ray ignition ring of the wind bowl bottom that is installed on burner, ignition ring is installed on the wind bowl by a retainer plate, and the two fulcrum thermoelectricity utmost points are installed in the ignition ring, and ignitor links to each other with ignition transformer.

2, stove and accessory according to claim 1 uses the liquid fuel direct fire unit, and it is characterized in that: a spout hole is arranged on the ignition ring, the limit for height overflow pipe is installed in the spout hole, the limit for height overflow pipe links to each other with auxiliary fuel tank.
