At attachment plug 24, as shown in Figure 2, connect Female Connector 43 with power line 41 and ground wire 42 with power supply terminal 22,22 and ground terminal 23.Though omitted diagram, power line 41 is connected in the supply unit of igniter outside.In addition, ground wire 42 is grounding to the burner body.Ground wire 42 the ground connection of burner body by utilizing supply unit etc. and can easily implement.
, make voltage by ignition transformer 12, thereby produce high voltages with in the discharge ignition apparatus 1 at such burner at lead-out terminal 26 from the boost in voltage of power supply terminal 22 inputs to regulation by high-voltage generating device 2.This high voltage is applied to the sparking electrode 31 of spark plug 3 from lead-out terminal 26, produces sparks from the leading section (spark discharge end) 32 of sparking electrode 31.Discharge ignition apparatus 1 catches fire gas-fired mouth and kerosene burner etc. by the spark that the leading section 32 at sparking electrode 31 produces.
As described above, with in the discharge ignition apparatus 1, ground terminal 23 and power supply terminal 22,22 are configured to the same one side (lower surface 21) of external box of microvave 11 at the burner of this form of implementation.In addition, power supply terminal 22,22 and ground terminal 23 centralized configuration are to the attachment plug 24 of 3 butt.Like this, can realize miniaturization and province's areaization of high-voltage generating device 2.By making high-voltage generating device 2 province's areaizations, can alleviate the consideration of the design of burner side.In addition, focus on a part, can be reduced at the connection structure of each terminal by power supply terminal 22,22 and ground terminal 23 with ignition transformer 12, simultaneously, the easily power line 41 of jockey outside and ground wire 42.Like this, can reduce the installation cost and the installation cost of discharge ignition apparatus 1.
The 3 terminal type connectors such as attachment plug 24 grades of above-mentioned 3 butt for example as shown in Figure 3, and are effective especially to the high-voltage generating device 2 with small-sized ignition transformer 12.That is, in the occasion that disposes ground terminal separately, the miniaturization of high-voltage generating device 2 and province's areaization suffer damage.And be connected tectosome, thereby can further promote the miniaturization of high-voltage generating device 2 and economize areaization by power supply terminal 22,22 and ground terminal 23 being focused on 1 by 3 terminal type connectors.In addition, in such occasion, the easily power line of jockey outside and ground wire.
In addition, in this form of implementation, be suitable for the discharge ignition apparatus 1 that directly connects sparking electrode 31 and lead-out terminal 26.Directly the discharge ignition apparatus 1 that connects structure can support discharge ignition apparatus 1 integral body by at the burner body spark plug 3 only being installed.That is, high-voltage generating device 2 also can not be installed on the burner body.In such occasion, by using 1 pair of attachment plug 24,43 ground terminal 23 is connected to ground wire 42, can by easily and also simple structure with the secondary earth of ignition transformer 12 to the burner body.Like this, do not damage the component costs of the discharge ignition apparatus 1 that the simplification by installation constitution causes and the minimizing effect of installation cost, can improve the acting characteristic and the reliability of ignition transformer 12.
Below, with reference to Fig. 4 2nd form of implementation of burner of the present utility model with discharge ignition apparatus is described.The part identical with Fig. 1 and Fig. 2 adopted same-sign, and part is omitted its explanation.Fig. 4 illustrates the occasion that high-voltage generating device 2 and spark plug 3 must be set with leaving.That is, spark plug 3 is installed on the nearby position of burner etc.On the other hand, high-voltage generating device 2 is arranged at the space of vacating in the burner etc. sometimes, and in such occasion, spark plug 3 leaves setting with high-voltage generating device 2.
Burner shown in Figure 4 has and the sparking electrode that spacing respective length be set 31 of spark plug 3 with high-voltage generating device 2 with discharge ignition apparatus 1.Engage by sparking electrode 31 between high-voltage generating device 2 and the spark plug 3 with the intensity that mechanically supports high-voltage generating device 2.Therefore, by only spark plug 3 being installed on the burner body, can support burner discharge ignition apparatus 1 integral body.In such occasion, the attachment plug 24 (3 terminal type connector) with power supply terminal 22,22 and ground terminal 23 also works effectively.Therefore, can realize the reduction of the needed cost of ground connection (installation cost and installation cost) of ignition transformer 12 and miniaturization etc.
Fig. 5 illustrates the discharge ignition apparatus 1 with tortuous sparking electrode 31.For example, gas heater unit in recent years is owing to the restriction that the place is set requires slimming.When inside of the water heater unit that discharge ignition apparatus 1 is assembled into slimming etc., existence must be disposed the occasion of sparking electrode 31 circuitously.Therefore, discharge ignition apparatus 1 shown in Figure 5 has tortuous sparking electrode 31.By utilizing tortuous sparking electrode 31, can like a cork high-voltage generating device 2 be configured to the inside of the water heater unit etc. of slimming.
In addition, around the sparking electrode 31 of complications, be that the border disposes the 1st insulation tube 41 and the 2nd insulation tube 42 with the zigzag part.The major part of the exposed division 37 of sparking electrode 31 is covered by 2 insulation tubes 41,42.Like this, by with the zigzag part of sparking electrode 31 as the border, cover sparking electrodes 31 by the 1st insulation tube 41 and the 2nd insulation tube 42, can cover the major part of the exposed division 37 of sparking electrodes 31 by insulation tube 41,42.In the occasion of the sparking electrode 31 of linearity shown in Figure 4, also can cover certainly by 1 insulation tube.
In addition, by cover the exposed division 37 of sparking electrode 31 by insulation tube 41,42, can suppress noise from exposed division 37.Like this, can prevent to be present in misoperation near the control electronics such as microcomputer of the position of sparking electrode 31.In addition, insulation tube 41,42 also works as the auxiliary material of spark plug 3 with the mechanical engagement of high-voltage generating device 2.Therefore, can improve the supporting precision of high-voltage generating device 2 that the occasion of spark plug 3 only is installed at the burner body.
Below, with reference to Fig. 6 3rd form of implementation of burner of the present utility model with discharge ignition apparatus is described.The part identical with Fig. 1～Fig. 5 adopted same-sign, and part is omitted its explanation.Fig. 6 illustrates the discharge ignition apparatus 50 that is electrically connected 26 of the lead-out terminals of the sparking electrode 31 of spark plugs 3 and high-voltage generating device 2 by high-tension cable 51.
That is, with in the discharge ignition apparatus, being connected of the sparking electrode of spark plug and the lead-out terminal of high-voltage generating device not necessarily is limited to direct connection structure at burner of the present utility model.The also applicable discharge ignition apparatus 50 that is electrically connected 26 of sparking electrodes 31 and lead-out terminals as shown in Figure 6 by high-tension cable 51 of the utility model.In such occasion, also can realize the facilitation that is connected of the simplification, power line and the ground wire that are connected structure of power supply terminal 22 and ground terminal 23, and based on their reduction of installation cost and installation cost.
