Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ignition device for an oil combustor that can ignite without tilting the combustion tube.

BACKGROUND OF THE INVENTION In general, there are two types of ignition devices for oil combustors: one type that ignites the combustion tube while tilting it by pressing the ignition button, and the other type that ignites the combustion tube while it remains stationary without tilting it. The latter static type ignition device has recently become popular because it produces less odor when ignited. As shown in FIGS. 7 and 8, when the ignition button 1 is pressed in the direction of the arrow Y against the spring 2, the stationary type ignition device is activated along with the sliding base plate 4 along the support plate 3. The body 5 moves in the same direction, and the ignition heater 6 approaches the burner section. On the other hand, the operating body 5
Since the operating groove 7 of the operating portion 5b rotates the connecting rod 8 that engages the other end 8a, the shutter 9 rotates downward. Then, the ignition heater 6 ignites the lamp wick 11 through the opened ignition window 10.
After that, when the pressing force is removed from the ignition button 1, the ignition heater 6 returns to its original position due to the repulsive force of the spring 2.
The shutter 9 closes the ignition window 10 and ignition is completed.

Problems that the invention aims to solve However, in this ignition system, since the ignition heater 6 is located directly below and very close to the combustion tube 12, when the wind resistance test specified by JIS is conducted,
The flame Fa blowing out from the combustion tube 12 burns out the ignition heater 6 and the lead wire, and also burns out the insulator 13.
Although it is covered by the terminal cover part 5a, it is made of an insulating material such as resin, so if it is exposed to heat for a long time, it will burn out and the ignition device may not be able to be used again. had. In addition, in order for the ignition heater 6 to slide quickly against the ignition window 10, the lower reflector of the oil combustor must be positioned higher due to its structure.As a result, the rear reflector radiates heat from the combustion tube. This has disadvantages in that the radiation area becomes small and the appearance is impaired in terms of design.

This invention solves the above-mentioned problems, and makes it possible to reliably ignite the ignition heater, lead wires, and insulators even after the wind resistance test without burning out the ignition heater, lead wires, and insulators. The purpose is to improve the appearance by increasing the heat radiation area from the cylinder as much as possible, and to improve operability while more reliably preventing the risk of burnout.

Means for Solving the Problems In order to solve the above problems, the ignition device of the present invention is configured so that the shutter is opened by sliding the operating body and at the same time the ignition heater is rotated to ignite the wick. There is.

Function The present invention has the above-described configuration, which allows a large distance between the ignition heater and the combustion tube, and ensures reliable ignition without burning out the ignition heater, lead wires, or insulating plate even during wind resistance tests. The device can be reused and at the same time a sufficient radiation area can be secured.
Moreover, it is possible to reliably resist the rotational moment applied to the operating body during ignition operation, and it is possible to maintain good ignition operation over a long period of time.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. In the figure, 21 is a tank, 22 is a cylindrical wick guide tube having a large number of small holes 23 on the outer periphery of the upper end, and 24 is a lamp wick disposed inside the tube so as to be movable up and down. 25 is the core guide tube 22
This is a combustion tube placed on top of the cylinder. These constitute a burner section. To explain the ignition device for igniting this burner section, reference numeral 26 is an ignition window provided in the wick guide tube 22. 27 is a shutter that can be opened and closed and normally closes the ignition window 26.
2 It is curved to follow the wall. 28 is a connecting body with one end fixed to the shutter 27 and the other end 28a bent at a right angle; 29 is an ignition board attached to the core guide tube 22, which rotatably supports the connecting body 28 in the middle; A slide guide piece 29a is provided so as to have a substantially U-shaped cross section, and horizontal elongated holes 29b are provided in opposite side walls of the slide guide piece 29a. 30 connects one end to the ignition board 29 with a support shaft 31
It is a rotating body that is rotatably supported by a rotating body, and has a heater holding portion 33 that holds an ignition heater 32 at the other end. Further, this rotating body 30 is provided with elongated holes 30a on both side walls, which face and intersect with the ignition board 29. 34 is a lead wire for the power supply of the ignition heater 32, and its terminal portion 35 is brought into pressure contact with the ignition heater 32. 36 is an insulator that protects the terminal portion 35 of the ignition heater 32, and is molded from a material such as resin. A holding spring 37 is interposed between the heater holding portion and the insulator, and holds the insulator 36. 38 is an abbreviated cross section U where the operation knob 39 is attached.
This actuating body has an actuating pin 40 inserted through the elongated hole 39b of the ignition board 39 and the elongated hole 30a of the rotating body 30, and the other end 28a of the connecting body 28 is attached to the side surface of the actuating body 38. A sliding groove 38a for sliding is provided. Reference numeral 41 denotes a slide hole formed horizontally in the lower part of both side walls of the actuating body 38, and is fitted into a guide pawl 42 extending from the lower part of the ignition board 29 to ensure linear movement of the actuating body 38. , it's easy. 43 is ignition heater 3
This is a contact point for energizing 2. 44 is the above ignition board 2
9 and the actuating body 38
The ignition spring is installed between the holding pieces 38b provided in the ignition spring. Reference numeral 45 denotes a cover body attached to the upper part of the slide guide piece of the ignition board 29, and the bent piece 45a is adapted to abut against the wall of the core guide cylinder 22.

In the above configuration, when the operating knob 29 is pressed in the direction of arrow A, the operating pin 40 is moved to the ignition board 29.
The rotating body 30 is slid in the long hole 29b of and the long hole 30a of the rotating body 30, and the rotating body 30 is rotated in the direction of the arrow B using the support shaft 31 as a fulcrum. Therefore, the ignition heater 32 also rotates in the direction of arrow B as the ignition heater 32 rotates. At this time, the shutter 27 rotates downward as the other end 28a of the connecting body 28 rotates clockwise along the slide groove 38a as the operating body 38 slides in the direction of arrow A. Then, the ignition heater 32 ignites the lamp wick 24 through the opened ignition window 26 (see FIG. 2). Thereafter, when the pressure is removed from the operating knob 39, the ignition heater 32 returns to its original position due to the repulsive force of the ignition spring 44, while the shutter 27 closes the ignition window 26 and ignition is completed.

Here, as is clear from FIGS. 1 and 2, the ignition heater 32 is located not directly below the combustion tube 25 but diagonally below it, and even when a wind resistance test is conducted, no air blows out from the combustion tube 25. The ignition heater 32 will not be burnt out due to the flame F. Further, since the insulator 36 and the lead wire 34 are located further apart than the ignition heater 32, the flame F does not touch them. Also, the cover body 4 attached to the upper part of the slide guide piece 29a of the ignition board 29
5 only has an opening 45b that is large enough for the ignition heater 32 to pass through, and it reliably blocks the flame blown out from the combustion tube 25 and protects the insulator 36 and the lead wire 34 from the flame F. There is. Furthermore, by bringing the bent piece 45a into contact with the wall of the core guide tube 22, the cover body 45 comes into contact with the ignition board 29 at two points, and the contact with the core guide tube wall, and rotation when the operating body slides. Another advantage is that dynamic moments can be resisted more reliably.

Furthermore, in this configuration, by moving the ignition heater 32 by rotational movement, the height of the ignition device can be made lower than in the conventional configuration. Therefore, as shown in FIG. 6, the position of the lower reflector 46 can be lowered, thereby increasing the area of the front reflector 47 and increasing the radiation area without changing the height of the main body 48. Not only can this be done, but it is also advantageous in terms of design.

Effects of the invention As described above, according to the invention, by rotating the ignition heater and igniting the wick through the ignition window, it is possible to increase the distance between the ignition heater and the combustion tube, and it is possible to conduct a wind resistance test. Even in the event of a fire, the ignition heater, insulator, and lead wire can be reused without burning out. Moreover, when incorporated into an oil combustor, it is possible to secure a sufficient radiation area, fully exhibit the characteristics of stationary ignition, and protect the ignition heater part from flames during wind resistance with the cover body. Burnout etc. can be more reliably prevented,
Further, during the ignition operation, it is possible to reliably resist the rotational moment applied to the operating body, and the ignition operation can be maintained in good condition over a long period of time, which has great effects.
