Description

  The present invention relates to a discharge type ignition device for an oil combustor that uses a discharge to ignite a core.

  As an ignition device for an oil combustor, there is one that uses a dry battery as a power source to generate a discharge spark using a discharge electrode for ignition and a counter electrode to ignite the core. When using a dry cell as a power source, there is a problem that the spark due to discharge is weak and the power source voltage fluctuates greatly. For this reason, the discharge electrode needs to be arranged so as to be in contact with or slightly buried in the side surface of the core, and to maintain the dimensions of the core and the electrode at the optimum position.

  Further, in the case of a core up-down type oil combustor, burning of the core cannot be avoided by using it for a long period of time, and the calorific value expected by the burned core cannot be obtained. For this reason, by changing the maximum core height, the expected heating value is obtained by changing the core height at the maximum heating value. (See Patent Document 1)

Japanese Utility Model Publication No. 61-19286

  Because the core is made of fiber, deformation is likely to occur, and even if the electrode is attached correctly, it is difficult to maintain the positional relationship with the electrode, the height of the core changes, and the tip shape of the core If there is a slight shift in the positional relationship between the lead and the discharge electrode due to deformation, the spark will not ignite from the lead even if discharge occurs, or the electrode will be buried in the lead and white smoke will be generated. It may not ignite just by getting out. Further, in the structure of Patent Document 1, the optimal positional relationship was obtained when the core was new, but when the maximum core height was changed, the discharge electrode and the counter electrode were buried in the core, and the discharge occurred. May not ignite.

  For this reason, it is conceivable to install a part for pressing the side surface of the core separately from the electrode. However, if a large part is arranged on the side surface of the core, the flow of combustion air may be hindered and the combustion performance may be deteriorated. Therefore, it was a structure with low feasibility. In the present invention, a structure satisfying both the certainty of ignition and the stability of combustion is realized.

  The present invention solves the above-described problem. A core 4 is mounted in a gap of a core housing cylinder 3 constituted by a core inner cylinder 1 and a core outer cylinder 2 so as to be movable up and down, and a side surface and a gap of the core 4 are provided. An ignition window hole 5 in the core outer cylinder 2 facing each other, a discharge electrode 6 that is passed through the ignition window hole 5 to a side surface of the core 4, and a discharge electrode 6 on the core outer cylinder 2 side. A counter electrode 7 disposed above and an insulator 8 covering the outer periphery of the discharge electrode 6 so as to form an insulating state with the counter electrode 7 are provided, and the core 4 protrudes above the core housing cylinder 3. In the oil combustor that discharges sparks between the discharge electrode 6 and the counter electrode 7 to ignite the core 4, the core 4 is configured in a state in which the warp 4A and the weft 4B are knitted. The discharge electrode 6 is not positioned on the core 4 at a position lower than the first weft thread 4b closest to the tip of the core 4. And the tip of the discharge electrode 6 is located above the first weft thread 4b and below the tip of the core 4, and the tip of the counter electrode 7 is above the discharge electrode 6. The core 4 that is positioned on the side of the core outer cylinder 2 with respect to the tip position of the discharge electrode 6 and protrudes above the core housing cylinder 3 has the first weft thread 4b in contact with the discharge electrode 6 and the A discharge ignition device for an oil combustor, characterized in that a space 9 is formed between the discharge electrode 6 and the counter electrode 7 by being brought close to the core inner cylinder 1 side.

  Further, the tip of the discharge electrode 6 is inclined toward the side of the core inner cylinder 1, so that the core 4 is not greatly deformed at the position of the first weft thread 4b. The space 9 can be formed by being pushed to the inner cylinder 1 side, and the discharge electrode 6 can be brought into contact with the side surface of the core 4 without being embedded in the core 4.

  The ignition window hole 5 is provided in a corner portion between a side surface of the core outer cylinder 2 and an outer flame cylinder receiver 2a continuous with the upper portion of the core outer cylinder 2, and the insulator 8 is provided in the ignition window hole. 5, the side surface of the core outer tube 2 and a part of the outer flame tube receiver 2 a are configured, and the counter electrode 7 penetrates the side surface of the insulator 8 and is formed on the side surface of the core 4. It is arranged between the core 4 and the insulator 8, and the insulator 8 has a distance L1 between the discharge electrode 6, the core outer cylinder 2 and the outer flame cylinder receiver 2a. By being set to be longer than the distance L2 between the tip of the electrode 6 and the counter electrode 7, no discharge occurs from the discharge electrode 6 toward the core outer tube 2, and the discharge electrode 6 is surely formed. And the counter electrode 7 can generate a discharge.

  Further, the discharge electrode 6 penetrates the insulator 8 and is disposed on the side surface of the core 4 and is disposed along a vertical center line of the insulator 8, and the counter electrode 7 is disposed on the insulator 5. The discharge electrode 6 and the counter electrode 7 are arranged close to one end of the upper surface of the metal plate, bent in a horizontal direction at a position above the core 4, and projected at the tip above the discharge electrode 6. Since the distance between the tips is the shortest, a discharge can be generated between the tip of the discharge electrode 6 and the counter electrode 7.

In the present invention, the discharge electrode 6 comes into contact with the first weft thread 4b of the core 4 and pushes it toward the inner cylinder 1 side. The core 4 is made so that the warp threads 4A are bundled with the weft threads 4B. Since the bundle of warps 4A is deformed when 4b is pressed, the discharge electrode 6 is not buried in the core 4 even in the fiber core 4, and the side surface of the core 4 can be pressed to the core inner cylinder 1 side. A space 9 can be formed between the tip of the discharge electrode 6 and the counter electrode 7. For this reason, discharge can be reliably performed between the tip of the discharge electrode 6 and the counter electrode 7, and the tip of the discharge electrode 6 is in contact with the side surface of the core 4 below the tip of the core 4. The fuel at the tip of the core 4 can be ignited by a spark.
Further, even when the height of the tip position of the core 4 at the maximum core height changes, the core 4 does not enter between the discharge electrode 6 and the counter electrode 7, and the discharge electrode 6 moves toward the counter electrode 7. Since discharge was performed and the side surface of the core 4 was ignited, the certainty of ignition could be improved.

  Further, since the discharge electrode 6 can push the core 4, the parts for pushing the core 4 are not necessary, and the discharge electrode 6 that contacts the side surface of the core 4 is made of a wire, and is supplied to the core 4. The combustion air flow was not obstructed and the combustion stability was improved.

  In addition, the discharge electrode 6 is inclined toward the inner tube 1 side so that the tip of the core 4 is pushed to a predetermined position on the inner tube 1 side to form a space 9. Since the core 4 is not greatly deformed at the position of the weft thread 4b, the vertical movement of the core 4 is not hindered when the discharge electrode 6 contacts the first weft thread 4b, and the operability when the core 4 moves up and down is improved. It was possible to achieve without loss.

Further, the ignition window hole 5 is provided at the corner between the side surface of the core outer cylinder 2 and the external flame cylinder receiver 2a, and the insulator 8 fitted in the ignition window hole 5 is connected to the side surface of the core outer cylinder 2 and the external flame cylinder. The discharge electrode 6 penetrates the side surface of the insulator 8 and is placed on the side surface of the core 4, and the discharge electrode 6 is positioned between the core 4 and the insulator 8. Thus, it could be configured not to face the side surface of the core outer cylinder 2. In this configuration, since the insulator 8 can ensure a certain distance from the side surface of the core outer tube 2 and the outer flame tube receiver 2a, the distance from the discharge electrode 6 to the core outer tube 2 and the outer flame tube receiver 2a. L1 can be made longer than the distance L2 between the tip of the discharge electrode 6 and the counter electrode 7.
For this reason, even if the discharge electrode 6 is located in the core housing cylinder 3, there is no discharge from the discharge electrode 6 toward the side surface of the core outer cylinder 2 or the outer flame cylinder receiver 2a. A discharge can be generated between the counter electrode 7 and the discharge electrode 6 can be brought into contact with the first weft thread 4b.

  Further, the discharge electrode 6 is disposed along the vertical center line of the insulator 8, the counter electrode 7 is disposed at one end of the upper surface of the insulator 8, and the counter electrode 7 is positioned above the core 4. The tip of the discharge electrode 6 and the counter electrode 7 are arranged so that the distance between the tips of the discharge electrode 6 and the counter electrode 7 is the shortest. 7, the discharge electrode 6 is in contact with the side surface of the core 4, so that the discharge can be caused to ignite along the side surface of the core 4 above the discharge electrode 6. It is possible to improve the certainty of ignition.

It is a cross-sectional view of the principal part of the ignition device of the oil combustor which shows the Example of this invention. It is a side view of the ignition device of the oil combustor which shows the Example of this invention. It is sectional drawing of the principal part of the oil combustor provided with this invention product.

  The present invention will be described with reference to the embodiments shown in the drawings. Reference numeral 10 denotes an oil tank for storing fuel, 1 denotes a core inner cylinder formed from a central portion of the bottom plate of the oil tank 10, and 2 denotes a core outer cylinder provided on the upper surface of the oil tank 10. Reference numeral 3 denotes a core housing cylinder constituted by the core inner cylinder 1 and the core outer cylinder 2, 4 is a core mounted in the gap between the core housing cylinder 3 so as to be movable up and down, and the core 4 is accommodated by a core lifting device (not shown). It moves up and down in the gap of the tube 3.

  The lower part of the core 4 extends into the fuel in the oil tank 10, and the fuel in the oil tank 10 is sucked up and supplied to the tip of the core 4 at the lower part of the core 4. Reference numeral 5 denotes an ignition window hole formed on the side surface of the core outer cylinder 2, 6 denotes a discharge electrode inserted through the ignition window hole 5 and viewed on the side surface of the core 4, and 7 denotes a discharge electrode 6 on the core outer cylinder 2 side. , A counter electrode disposed above the electrode 8, an insulator covering the outer periphery of the discharge electrode 6, and an oscillation circuit 13 connected to the discharge electrode 6. When an ignition operation is performed, power is supplied to the oscillation circuit 13, and the oscillation circuit 13 operates to cause a spark discharge between the discharge electrode 6 and the counter electrode 7.

  2a is an external flame tube receiver continuous to the upper portion of the core outer tube 2, 11 is an internal flame tube disposed on the upper portion of the core inner tube 1, and 12 is an external flame disposed on the outer flame tube receiver 2a of the core outer tube 2. When the discharge is performed between the discharge electrode 6 and the counter electrode 7 by causing the tip 4 to be raised by the lead lifting device so that the tip protrudes above the lead housing tube 3 and performing an ignition operation, the lead 4 The fuel supplied to the tip is ignited to start combustion, and the generated combustion flame and combustion gas are sent to the gap between the inner flame cylinder 11 and the outer flame cylinder 12. Then, the air that rises in the internal space of the core inner cylinder 1 and flows into the inner flame cylinder 11 and is supplied to the gap, and the air that is supplied to the gap from the outside of the outer flame cylinder 12 are vaporized from the core 4. Combustion is completed by mixing with the spent fuel. At the time of extinguishing the fire, the core 4 is lowered and the fire is extinguished when the core 4 is accommodated in the core accommodating cylinder 3.

The core 4 is composed of a fuel suction core and a heat-resistant core. The fuel suction core is knitted with cotton yarn, and the heat-resistant core is knitted with glass fiber yarn. In the heat-resistant core, a plurality of warp yarns 4A are folded back and forth many times, and weft yarns 4B are arranged in the transverse direction so as to intersect the warp yarns 4A, and a plurality of warp yarns 4A are bundled. The combustion part at the tip is formed by cutting the part at a predetermined position.
4b is the 1st weft located in the most tip side among a plurality of wefts 4B arranged at intervals in the up-and-down direction, and when the tip of core 4 is projected above core storage cylinder 3, The first weft 4b is provided so as to be positioned in the gap of the core housing cylinder 3 or at substantially the same height as the upper opening of the core housing cylinder 3.

  Since the discharge type ignition device of the oil combustor does not ignite if it is separated from the core 4 even if it discharges between the discharge electrode 6 and the counter electrode 7, the discharge electrode 6 is brought into contact with the side surface of the core 4, It is necessary to arrange so that it is slightly buried. However, the tip of the core 4 made of fiber is notched or frayed, the tip of the core 4 spreads toward the core outer cylinder 2, or the height of the tip of the core 4 changes due to a dimensional error. May be buried in the core 4, and even if it is discharged, white smoke may be generated and it may not be ignited.

  The present invention is for maintaining the dimensions of the core 4 and the electrode at the optimum position and realizing the improvement of the ignition performance. The ignition window hole 5 is formed on the side of the core 4 on the side of the core outer cylinder 2 side. The insulator 8 is inserted into the ignition window hole 5 from the outside of the core outer cylinder 2 and positioned in contact with the ignition window hole 5. Reference numeral 8 a denotes a bracket for fixing the insulator 8 positioned in the ignition window hole 5 to the core outer tube 2.

  The discharge electrode 6 passes through the side surface of the insulator 8 at a position below the first weft thread 4b of the core 4 and protrudes into the core housing cylinder 3 so as to be seen on the side surface of the core 4. The tip of the discharge electrode 6 is upward The discharge electrode 6 protrudes from the outer surface of the core 4 toward the inner core tube 1 side. The tip of the discharge electrode 6 is located above the first weft thread 4 b and below the tip of the core 4.

  When the lead 4 is raised and the tip of the lead 4 protrudes above the lead receiving cylinder 3, the discharge electrode 6 is in contact with the side surface of the lead 4 and the first weft 4 b, and the discharge electrode 6 and the first weft of the lead 4. Since 4b cross | intersects, the 1st weft 4b can be deform | transformed and it can push to the core inner cylinder 1 side. Since the warp 4A is bundled at the position of the first weft 4b, the bundle of warp 4A is pushed and deformed together with the first weft 4b toward the core inner cylinder 1, and even the fibrous core 4 is discharged. The electrode 6 is not buried in the core 4, and the side surface of the core 4 can be pushed toward the core inner cylinder 1 side.

  The counter electrode 7 extends above the core housing cylinder 3 on the side of the core outer cylinder 2 relative to the discharge electrode 6, and is bent in a substantially L shape at a higher position than the discharge electrode 6 to be above the tip of the discharge electrode 6. The tip position of the counter electrode 7 is located closer to the core outer tube 2 than the tip position of the discharge electrode 6.

  The core-up and down type oil combustor uses a dry battery as a power source, so there is a problem that the voltage fluctuation is large and the discharge spark is weak, and the distance between the discharge electrode 6 and the counter electrode 7 is set to the optimum positional relationship for ignition. Then, the distance between the core 4 and the discharge electrode 6 / counter electrode 7 is reduced. Reference numeral 9 denotes a space formed in a portion where the core 4 is pushed to the core inner cylinder 1 side by the discharge electrode 6, and the tip of the counter electrode 7 is located in the space 9 so that it does not come into contact with the core 4. Further, the positional relationship between the discharge electrode 6 and the counter electrode 7 can be kept constant. When a discharge is generated from the tip of the discharge electrode 6 toward the counter electrode 7, the core 4 containing fuel becomes an insulator, and extends from the tip of the discharge electrode 6 along the side surface of the core 4 that is an insulator. Since the tip of the discharge electrode 6 is in contact with the side surface of the core 4, the fuel in the core 4 above the discharge electrode 6 can be ignited.

  The core 4 has a large dimensional error at the cut end, and the length of the warp 4A may change, and the position of the tip of the core 4 may increase. However, the tip of the core 4 pushed by the discharge electrode 6 has a tip from the counter electrode 7. Since it faces away, the core 4 and the counter electrode 7 do not contact each other even when the tip position of the core 4 becomes high, and the positional relationship between the core 4, the discharge electrode 6 and the counter electrode 7 can be maintained constant. Therefore, the certainty of ignition was improved.

  Recently, there is a core lifting device that can change the maximum core height, and if the core 4 is burned out by using an oil combustor for a long time, the expected heat generation cannot be obtained, so the core 4 is old. In this case, the original heating value can be obtained by increasing the protruding height of the core 4 at the maximum heating value. However, when the core height is changed, the tip of the core 4 rather than the counter electrode 7 is obtained. The position may be higher. Even in this case, the core 4 pressed by the discharge electrode 6 faces the direction away from the counter electrode 7, so that the core 4 and the counter electrode 7 do not contact each other, and the core 4, the discharge electrode 6, and the counter electrode 7 are not in contact with each other. The position relationship between the two can be maintained constant, so that it is possible to support a type of core lifting device that can change the maximum core height.

  By the way, the first weft thread 4b comes into contact with the discharge electrode 6 when the core 4 is lifted, and the first weft thread 4b moves in the lateral direction with respect to the rising core 4. Become. In another embodiment of the present invention, the tip of the discharge electrode 6 is inclined toward the inner core tube 1 side, and the side surface of the core 4 is inclined along the inclination of the discharge electrode 6. The tip of the discharge electrode 6 and the tip of the counter electrode 7 maintain a predetermined positional relationship. On the other hand, the discharge electrode 6 does not penetrate deeply into the core 4 at the position of the first weft thread 4b, and the deformation of the first weft thread 4b toward the core inner cylinder 1 is less with respect to the rising core 4. Therefore, the resistance when the core 4 is moved up and down can be reduced, and a smooth core up and down operation is possible.

  Further, in this embodiment, the ignition window hole 5 is formed at the corner portion between the side surface of the core outer cylinder 2 and the outer flame cylinder receiver 2 a, and the insulator 8 matches the shape of the ignition window hole 5. A step portion is formed on the back side of the insulator 8. The insulator 8 is inserted into the ignition window hole 5 from the outside of the core outer cylinder 2, the insulator 8 abuts against the inner edge of the ignition window hole 5, and the step portion of the insulator contacts the lower surface of the outer flame cylinder receiver 2a. When the bracket 8 a is attached to the lower portion of the insulator 8, it is fixed to the ignition window hole 5. The ignition window hole 5 is closed with an insulator 8, and the insulator 8 constitutes a side surface of the core outer tube 2 and a part of the outer flame tube receiver 2a.

  The discharge electrode 6 penetrates the central part of the side surface of the insulator 8 and looks into the side surface of the core 4, and the tip is bent upward to form a substantially L shape. The side surface of the core 4 and the side surface of the insulator 8 are formed. The distance between the discharge electrode 6 and the side surface of the core outer cylinder 2 is secured by the insulator 8. Further, the upper surface of the insulator 8 is extended to a position protruding upward from the outer flame tube receiver 2a, and the insulator 8 is positioned between the discharge electrode 6 and the outer flame tube receiver 2a. The insulator 8 also secures the distance from the outer flame tube receiver 2a. On the other hand, there is a core 4 containing fuel between the discharge electrode 6 and the core inner cylinder 1, and the core 4 is an insulator.

  The distance L2 between the discharge electrode 6 and the counter electrode 7 is set so as to have an optimum positional relationship in which discharge occurs from the discharge electrode 6 to the counter electrode 7. In order to generate a discharge, it is necessary to set the distance L1 between the discharge electrode 6 and the core outer tube 2 and the outer flame tube receiver 2a to be longer than the distance L2 between the discharge electrode 6 and the counter electrode 7. is there.

  In the present invention, even if the discharge electrode 6 is disposed in the core housing cylinder 3, the discharge electrode 6 does not directly face the side surface of the core outer cylinder 2 or the external flame cylinder receiver 2 a, and the discharge electrode 6 is formed by the insulator 8. Since the distance L1 between the core outer tube 2 and the outer flame tube receiver 2a can be secured, the distance L1 between the discharge electrode 6 and the core outer tube 2 and the outer flame tube receiver 2a is equal to the distance between the discharge electrode 6 and the counter electrode 7. It was possible to set longer than L2. For this reason, the discharge from the discharge electrode 6 does not go to the core outer tube 2 or the outer flame tube receiver 2a but certainly goes to the counter electrode 7, and the reliability of ignition can be improved.

  Further, although the ignition window hole 5 is provided in the side surface of the core outer cylinder 2 and the external flame cylinder receiver 2a, the ignition window hole 5 is closed by the insulator 8, so that the core accommodating cylinder is opened from the ignition window hole 5. The structure in which no inflow of air that affects the combustion in 3 was realized. Further, the discharge electrode 6 contacts the side surface of the core 4, but since the discharge electrode 6 is made of a wire, there is no part that obstructs the flow of air on the side surface of the core 4, and the core 4 is uniform. Combustion air can be supplied, and combustion stability can be secured.

  In the embodiment of the present invention shown in FIG. 3, 8b is a mounting portion of the counter electrode 7 protruding upward from the upper surface of the insulator 8, and the mounting portion 8b is formed integrally with the insulator 8. The insulator 8 is disposed at one end on the upper surface. The counter electrode 7 extends upward through the upper surface of the mounting portion 8 b, is bent in the horizontal direction above the tip position of the discharge electrode 6, and the tip of the counter electrode 7 is seen above the discharge electrode 6. The counter electrode 7 is arranged from a position away from the tip of the discharge electrode 6 so that the distance between the tip of the discharge electrode 6 and the tip of the counter electrode 7 is the shortest.

  With this configuration, the discharge always occurs between the tip of the discharge electrode 6 and the tip of the counter electrode 7, so that the discharge always occurs along the side surface of the core 4 above the discharge electrode 6. The fuel of the wick 4 can be ignited, and the certainty of ignition can be improved.

  Further, when the counter electrode 7 is extended upward from the tip of the discharge electrode 6, the counter electrode 7 has a portion exposed from the insulator 8, but by providing a mounting portion 8 b that protrudes from the upper surface of the insulator 8, The attachment portion 8b is a reinforcing member for the counter electrode 7, and the strength of the counter electrode 7 can be ensured.
