Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ignition device for an oil combustor that can raise the wick and ignite the lamp by operating a lever.

Conventional technology Generally speaking, the ignition system for kerosene stoves is of the type that raises the wick to the combustion position and then presses the ignition button to bring the ignition heater into contact with the wick to ignite the ignition, or the ignition heater moves as the wick rises. First, there is a lever type lamp in which the ignition heater comes into contact with the lamp wick to ignite the lamp at the same time as the lamp rises to the combustion position. The latter lever-type ignition device has recently become popular due to its operability, as it allows for raising the wick and igniting the ignition with a single operation. In this lever type igniter, as shown in Figure 10, the wick 1 is connected to a wick up/down lever (not shown).
At the same time, the ignition lever 2 moves in the direction of arrow B in conjunction with the wick up/down lever, and the resin body 3 attached to the end of the ignition lever 2 moves upward in the direction of arrow A.
Due to this sliding movement, the ignition lifting plate 4 rotates about the support shaft 5 in the direction of arrow C. Reference numeral 6 denotes a rotating body which is rotatably supported by a support shaft 5 like the above-mentioned ignition lifting plate 4, and holds an ignition heater 7 at the other end, and this rotating body 6 is provided on the ignition board 8. Slide groove 8
a and the operating pin 9 inserted through the elongated hole 4a of the ignition lifting plate 4 and the elongated hole 6a of the rotating body 6, by sliding in the D direction due to the rotation of the ignition lifting plate 4 in the C direction. Rotate to. Accordingly, the ignition heater 7 also rotates in the direction C as the ignition heater 7 rotates, and the lamp wick 1 is ignited.

Problems to be Solved by the Invention However, in this ignition device, since the ignition heater rotates as the wick 1 rises, the ignition heater 7 comes into contact with the wick 1 while the wick 1 is still rising, and the ignition heater 7 The tip of wick 1 gets caught in the
This has the problem that the filament (not shown) of the ignition heater 7 made of a very thin wire may be deformed or broken, making it impossible to reliably ignite the lamp wick 1.

The present invention solves the above problem by bringing the ignition heater into contact with the wick when the wick has completely risen to the combustion position, so that the wick can be reliably ignited without damaging the ignition heater. It is intended to.

Means for Solving the Problems In order to solve the above problems, the ignition device of the present invention has a bent part at the end of the sliding trajectory of the resin body of the ignition lifting plate, and the ignition lifting plate of the resin body and the ignition lifting plate of the resin body. Protrusions are provided on opposing parts.

Function: With the above-described structure, the present invention can delay the approach of the ignition heater as the wick rises, and by bringing the ignition heater into contact with the wick immediately after the wick rises to the combustion position, the filament of the ignition heater is damaged. This prevents this from happening and ensures reliable ignition.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 9. In the figure, 21 is a cylindrical wick guide tube having a large number of small holes on the outer periphery of the upper end, and 22 is a lamp wick disposed inside the tube so as to be vertically movable. The lamp wick 22 is raised by moving the wick up/down lever 23 in the direction of arrow A, and lowered by moving in the direction of arrow B. 23a is a lead up/down knob inserted into the lead up/down lever. Next, the ignition device for igniting the lamp wick 22 will be described. Reference numeral 24 is an ignition window provided in the wick guide tube 21. Reference numeral 25 denotes a shutter that can be opened and closed and normally closes the ignition window 24, and is curved to follow the wall of the core guide tube 21. 26 is a connecting body with one end fixed to the shutter 25 and the other end 26a bent at a right angle; 27 is an ignition board attached to the core guide tube 21, which rotatably supports the connecting body 26 in the middle; Horizontal elongated holes 27b are formed in both side walls 27a bent into a substantially U-shape.
have. Reference numeral 28 denotes a rotating body whose one end is rotatably supported by a support shaft 29 on the ignition board 27, and has a heater holding portion 31 holding an ignition heater 30 at the other end. Further, this rotating body 28 is provided with elongated holes 28a on both side walls thereof, which face and intersect with the ignition board 27. 32 is the above ignition heater 30
The terminal portion 33 of the lead wire for the power source is pressed into contact with the ignition heater 30. 34 is ignition heater 3
This is an insulator that protects the terminal portion 33 of 0. Reference numeral 35 denotes a holding spring interposed between the heater holding portion 31 and the insulator 34, and holds the insulator 34. 3
Reference numeral 6 denotes an ignition lifting plate rotatably supported by the support shaft 29, and the ignition lifting plate 36 has a long hole 36a that faces and intersects with the ignition board 27. Reference numerals 37 denote the elongated hole 27b of the ignition board 27, the elongated hole 28a of the rotating body 28, and the ignition lifting plate 36.
This actuating body has an actuating pin 38 inserted through a long hole 36a, and slides within a slide guide piece 27c provided on the ignition board 27. A sliding groove 37a for sliding is provided. 39 is a contact point for supplying electricity to the ignition heater 30. Reference numeral 40 denotes a cover body attached to the upper part of both side walls 27a of the ignition board 27. Reference numeral 41 denotes an ignition lever. An ignition knob 41a is inserted into one end of the ignition lever 41, and a resin body 42 is attached to the other end.
A protrusion 42a is provided at a portion of the resin body 42 facing the ignition lifting plate 36, and the ignition lifting plate 36 has a bent portion at the end of a sliding trajectory along which the resin body 42 slides. A portion 36b is provided.

In the above configuration, when the ignition lever 41 is operated in the direction of arrow A, the wick up/down lever 23 also moves in the direction of arrow A in conjunction with the ignition lever 41, and the lamp wick 22 begins to rise. When the ignition lever 41 is ignited in the direction of arrow A, the protrusion 42a of the resin body 42 attached to the tip of the ignition lever 41 comes into contact with the ignition lifting plate 36 and slides on the bent part 36b of the ignition lifting plate 36. While moving, the ignition lifting plate 36 is rotated in the direction of arrow B using the support shaft 29 as a fulcrum. When the ignition lifting plate 36 rotates in the direction of arrow B, the operating pin 38 slides in the elongated hole 36a of the ignition lifting plate, the elongated hole 27a of the ignition board 27, and the elongated hole 28a of the rotating body 28, The rotating body 28 also rotates in the direction of arrow B using the support shaft 29 as a fulcrum. At this time, the shutter 25
As the connecting body 2 slides in the direction of arrow C of 7,
Since the other end 26a of the shutter 25 rotates clockwise along the slide groove 37a, the shutter 25 also rotates downward. Then, the ignition heater 30 enters through the opened ignition window 24. As the ignition lever 41 moves further in the direction of arrow A, the protrusion 42a of the resin body 42 attached to the ignition lever 41 in FIG. As the ignition lever 41 further moves in the direction of arrow A, the protrusion 42a of the resin body 42 slides on the slope 36c of the ignition lifting plate 36 and lifts the bent portion 36b, and at this time the ignition heater 30 The ignition window 2
4 and comes into contact with the lamp wick 22 to ignite it (see Figures 1 and 4). After that, when the pressure is removed from the ignition lever, the ignition heater 30 returns to its original position due to the repulsive force of the ignition spring 43, while the shutter 2
5, the ignition window 24 is closed and ignition is completed.

Here, in the ignition heater 30, the protrusion of the resin body 42 lifts the bent portion 36b of the ignition lifting plate 36 at once, so that the protrusion of the resin body 42 lifts the ignition lifting plate 36.
The ignition heater 30 can be rotated slowly until it comes into contact with the slope part 6, and the approach of the ignition heater 30 with respect to the rise of the lamp wick 22 can be delayed, so that the ignition heater 30 comes into contact with the lamp wick 22. This is just before the wick reaches the combustion position.
Therefore, the filament 30a of the ignition heater 30 will not be deformed or broken due to the wick 22 being caught in the ignition heater 30. 7 and 8 compare the relationship between the approach stroke S of the ignition heater and the rising wick height WH of the lamp wick in this embodiment and the conventional example. The horizontal axis represents the wick height in mm, and the fire pan 21a of the wick guide tube 21 is taken as a reference 0, and the vertical axis represents the approach distance of the ignition heater, and the outer peripheral surface of the lamp wick 22 is taken as a reference 0. According to the comparison in FIG. 8, at the beginning of the ignition operation, in this embodiment, the ignition heater stroke S with respect to the wick height WH is small, that is, the ignition heater 30 rotates more slowly than in the conventional example, but the ignition heater The height of the wick when the lamp 30 contacts the lamp wick 22 is 12.5 mm in this embodiment, whereas it is 10.5 mm in the conventional example, and in this example, the ignition heater 30 contacts the lamp wick 22 immediately before the lamp wick 22 is set at the combustion position. It's getting old. That is, the ignition heater 30 is the lamp wick 22.
It is designed not to get caught.

Further, in this configuration, a resin body 42 attached to the tip of the ignition lever 41 is used to lift the ignition lifting plate 36.
Since the ignition is performed by line contact using the protrusion of the resin body 42, the ignition operation is very smooth.
Since the ignition lever slides along the bent portion 36b of the ignition lifting plate 36, it has the advantage that the ignition lever oscillates from side to side.

Effects of the invention As described above, according to the invention, the ignition heater can be brought into contact with the wick just before it rises to the combustion position, and the ignition heater can be reliably ignited without damaging the filament of the ignition heater. By lifting the ignition lifting plate by sliding movement through line contact with the resin body, smooth and reliable ignition can be achieved.
