Abstract

PURPOSE:To shorten the fire extinguishing time in an emergency or falling down while preventing the generation of soots at the firing time by providing a rising piece only at a portion opposing a firing device on the outer periphery of an outer fire pan. CONSTITUTION:A wick 2 is exposed on a fire pan 3a by wick lifting and lowering means, and, thereafter, when an operating button 16 is pushed, a firing heater 4 provided on a slide vase 15 advances toward the wick 2 and, simultaneously a door 14 opens an opening part 5 by the operation of a cam piece 19. The firing heater 4 is inserted into the opening part and reaches the wick 2, and at the same time, is supplied with power to ignite the wick 2 via a lead wire 18. In this case, in the firing device, a rising piece 6 is provided only at a part of the outer fire pan 3a to provide an opening part 4 and only a cutout portion 8' of an outer flame cylinder 8 is fitted into the rising piece 6. Hence, the rise in the temperature of the outer fire pan 3a due to combustion can be made lower because a part which directly picks up heat is only a partial rising piece 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ignition device for a wick-type oil combustor.

Conventional configurations and their problems In general, there are two types of ignition devices: one that ignites one combustion tube by tilting it, and the fixed ignition that ignites with the combustion tube fixed. Fixed ignition is advantageous for reducing ρ air.

This fixed ignition? , the binding °C- is conventionally as shown in Fig. 3.
Drill a hole in the bottom of the ignition heater 52, fix the ignition heater 52 in this hole, and energize the ignition heater 52.
.

There was something that ignited the wick 53. The scary thing is the ignition heater 5
2 is always located near the lamp wick, so during combustion the catalytic combustion occurs on the surface of the heating element and becomes red hot, causing dust in the air to adhere to the surface of the heating element, significantly reducing ignition performance. There was a problem with deterioration. Further, since the bottom surface 1 of the fire pan is provided with a hole, there is a problem that condensed stones and oil vapor leak out from the gap between the hole and the ignition heater 2.

As a solution to this problem, a method as shown in FIG. 4 is known. Sunao) Chiko's ignition device +, 1 fire 1m5
A rising wall 54a forming a part of the combustion tube is provided on the entire outer circumference of the cylinder 4, and a hole 54b for inserting the heater 55 is provided in the rising wall 54a.
At the same time, a heater 5 is provided to fit this hole 54b).
5 so that it can move forward and backward, or') 1γ up rIj 54 a
The shack 5 opens and closes in conjunction with the advance and retreat of the heater 55.
6 is a provision.

With this ignition system, as mentioned above, the problem will disappear, but
Since the vertical J-wall 54a provided around the outer periphery of the fire pit 54 is a part of the combustion tube and reaches a high temperature, there is a problem that it becomes difficult to quickly extinguish the fire in an emergency. Furthermore, when the appliance falls over, the unburned gas that continues to evaporate from the upper part of the descending lamp wick 53 is obstructed by the vertical wall 54a (as described in item 1) and cannot quickly flow out to the outside.
There was also the problem that unburned gas remained in the surrounding area, making it more likely to cause embers.

OBJECTS OF THE INVENTION The present invention was made in view of the above-mentioned problems, and aims to shorten the extinguishing time in the event of an emergency or fall while preventing the generation of soot during ignition.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a rising piece only in the portion facing the ignition device on the outer periphery of the outer fire pan, and
A notch is provided at the lower end of the outer flame cylinder of the combustion tube that faces this standing piece, and an opening for ignition is provided in the standing piece, and the ignition heater is inserted through this opening. be.

Description of examples An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a core guide cylinder erected from approximately the center of an oil tank (not shown), and an inner fire pan 1 is provided at the upper end.
It has a. 2 is a vertically movable lamp wick fitted around the outer periphery of the wick guide tube 1; 3 is a wick outer tube that covers the outer periphery of the wick 2; it has an outer fire pan 3a at the top; A vertical piece 6 with an opening S through which the ignition heater 4 is inserted is formed.

This rising piece 6 forms a trapezoid. On the other hand, a trapezoidal notch 8' is provided at a part of the lower end of the outer flame tube 8 of the combustion tube 10, which consists of the inner flame tube 7, the outer flame tube 8, the outer tube 9, etc. The vertical ribs 6 are fitted in a substantially airtight state to the extent that the inflow of excess air 5 does not have an adverse effect on combustion. 11 is an ignition device, and the board 12 has a shaft 1.
3 is provided with a door 14 for opening and closing the opening 5. Further, the substrate 12 has a sliding base 15 that slides back and forth.
is attached to the slide table 15, and an operation button 16,
A heater socket portion 17 is provided. Further, the ignition heater 4 described above is attached to the heater socket portion 17.

18 is a lead wire that supplies power to the ignition heater.

19 is a cam piece formed on the sliding table 15; this cam piece 19
When the bent piece 13' of the shaft 13 is engaged with the lead groove 19' provided in the lead groove 19' and the ignition heater 4 is moved forward, the door 14 opens the opening 1 section 5.

In the configuration described below, the wick 2 is exposed to the fire pan 3a by a wick up/down means (not shown), and then the ignition heater 4 provided on the sliding base 15 is moved to the wick 2 by pressing the operation button 16. At the same time as the door 14 moves forward, the cam piece 19
The ignition heater 4 is inserted through the opening 5 to reach the lamp wick 2, and at the same time, electricity is applied through the lead wire to ignite the lamp wick 2. After ignition, the ignition heater 4 retreats and leaves the opening 5, and at the same time,
The door 14 closes the opening 5 and enters a combustion state.

Here, in this ignition device, the rising piece 6 is provided only in a part of the outer flame pan 3a to form the opening 5, and the combustion tube 10 has a notch 8' of the outer flame tube 8 that fits into the rising piece 6. Therefore, the temperature rise of the outer flame pan 3a due to combustion is due to the fact that the only part that directly picks up heat is the partial rising piece 6, and the rest is due to heat conduction from the outer flame tube 8 due to contact. Compared to the conventional example shown in the figure in which the entire circumference is a rising wall, the outer fire pan 3a
It is possible to lower the temperature of

In addition, when the appliance falls over, the combustion tube 10 can easily fall into the inner and outer fire pans 1a and 3a, partly because the rising pieces 6 are trapezoidal.
Then, most of the fire pan 3a except for the rising piece 6 is directly exposed to the outside air, and the unburned gas that continues to evaporate from the wick 2 smoothly flows out from the inner and outer fire pans 1a, 3a.

In addition, this ignition device has a combustion tube 10 when performing an ignition operation.
Since the lamp is not raised above the fire pans 1a and 3a, excess air does not enter the vicinity of the wick 2, and no soot is generated.

[Effects of the Invention] As is clear from the description of one embodiment, according to the present invention, the temperature of the fire pan can be lowered, so the fire extinguishing time in emergencies such as earthquakes can be shortened by a large amount of rIJ. At the same time, when the appliance falls over, the gas is discharged into the stove, so the extinguishing time at the time of this falling is also long (J The effects are significant, including the ability to prevent soot.
