Description

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

Conventional configurations and problems Generally speaking, this type of ignition device is known to have two types: one that ignites by tilting the combustion tube, and the fixed ignition that ignites with the combustion tube fixed. Fixed ignition is advantageous for

Conventionally, this fixed ignition device has a fire pan 1 as shown in Figure 4.
There was one in which a hole was made in the bottom of the lamp, an ignition heater 2 was fixed in the hole, and the ignition heater 2 was energized to ignite the lamp wick 3. This is because the ignition heater 2 is always located near the lamp wick, so petroleum vapor adheres to it, making it impossible to relight it. Also, the wire breaks because there is ignition heat 2 in the high temperature atmosphere. Furthermore, since the bottom surface 1 of the fire pan is provided with a hole, there is a problem that condensed petroleum vapor flows out from the gap between the hole and the ignition heater 2.

As a solution to this problem, a device as shown in FIG. 5 is known. That is, in this ignition device, a rising wall 4a is provided on the outer periphery of the fire pan 4, a hole 4b for inserting the heater 5 is provided in the rising wall 4a, and the heater 5 is provided in alignment with this hole 4b so that it can move forward and backward. The rising wall 4a is provided with a shutter 6 that opens and closes in conjunction with the advance and retreat of the heater 5.

In this ignition device, a rising wall 4a must be provided around the outer periphery of the fire pan 4, and the shape of the fire pan is special, making it impossible to share parts with kerosene stoves other than constant ignition, resulting in high costs and parts. There were problems such as complicated management.

Furthermore, when the appliance falls over, the gas that continues to evaporate from the upper part of the descending lamp wick is obstructed by the rising wall 4a and cannot quickly flow out to the outside, and as a result, the flame remains on this rising wall portion 4a, which takes time to extinguish. There was a big problem that it lasted a long time.

OBJECTS OF THE INVENTION The present invention was made in view of two sets of problems, and is aimed at reducing costs and shortening the time it takes to extinguish a store overturning.

In the above embodiment, not only the outer flame opening door 7 but also the outer cylinder 14 is provided with a door 13, but this may be omitted, and the outer cylinder can be opened by inserting the ignition heater 15 diagonally from below. The opening 14a can also be eliminated. In addition, in this device, the door 7 is held by the claw 8b from the outer flame cylinder 8 and slid up and down, and is moved by the claw 9a of the arm 9, but in addition to this, only the arm is used for raising, and the door is used for lowering. It is also possible to use a spring tensioned between the outer flame tube and the outer flame tube, or to use a cantilever spring method with one end fixed instead of a sliding method for opening and closing, as long as the purpose of the present invention is achieved. Any configuration is acceptable.

Effects of the Invention As is clear from the description of the embodiments, in the present invention, the ignition heater is inserted through the opening provided in the outer flame tube, so there is no problem even if the fire pan is in one layer, and the rising wall around the periphery of the fire pan is eliminated. be able to. Therefore, when the appliance falls over, gas does not accumulate on the rising wall around the fire pan and prolongs the extinguishing time, and the extinguishing time when the appliance falls down can be reduced by 11 times.

Also, since the fire pan does not need to be a special one with a raised wall, it can be used as a fixed ignition device and other ignition devices just by replacing the combustion tube, simplifying management by sharing parts. This enables significant cost reductions. Furthermore, if an opening is provided in the outer cylinder as in the embodiment so that, for example, the ignition heater enters in an arc shape, the height of the lamp wick can be set low, and the engagement between the arm and the opening/closing plate of a door, etc. If this is done only when igniting the fire, the combustion tube will fall freely from the top of the fire pan when the appliance falls over, making it possible to extinguish the fire in a shorter time.
