Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ignition heater part for maintaining combustion in kerosene stoves and the like.

Conventionally, there are two methods of igniting a lamp wick using an ignition heater:
It was hot.

1. A method in which the ignition heater is brought close to the wick from the inside or outside of the wick and ignited it.

2. A method in which an auxiliary wick for ignition is provided close to the wick, and the auxiliary wick is ignited by an ignition heater also fixed nearby, and the wick is ignited by the flame.

Method 1 above requires a complicated ignition heater moving mechanism. In addition, since the ignition heater is moved and pressed against the wick, the heater wire is susceptible to impact, which has the disadvantage that it is more likely to cause failures such as a drop in red-hot temperature or wire breakage. Further, although the second method does not require a mechanism for moving the ignition heater, it does require an auxiliary lamp wick and a mechanism for storing and moving the auxiliary lamp wick.

In particular, deformation of the auxiliary lamp wick tends to cause misalignment with the ignition heater, resulting in unstable ignition performance. The present invention aims to improve the ignition characteristics and simplify the ignition mechanism, and one embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure 1
is a rod-shaped heater body 1 made of heat-resistant porcelain, and a metal bar 3
A pair of through holes 1a and a square hole 2 are provided, through which the holes 1a and 2 are inserted. 3
are a pair of metal bars that do not protrude to the heater coil side but protrude to the lead wire side, and are fixed to the heater body 1 with adhesive.

4 is a heater coil, which is connected by welding or the like with a metal bar 3;
The welding location is buried within the heater body 1.

Reference numeral 5 denotes a holding metal fitting having a plurality of opening holes 6, one side of which is inserted into the square hole 2 of the heater body 1, and fixed with adhesive or the like.

Reference numeral 7 is an edible oil-based core material that is held in place by a holding metal fitting 5.

8 is a heater lead wire, 9 is an inner wick guide tube, 10 is an outer wick guide tube, and 11 is a wick, from the upper end of which projects a fire wick 12 that is thinner than the wick body.

This fire wick 12 is thin and highly flexible, and even if its tip comes into contact with the core material 7 through the opening hole 6 provided in the holding fitting 5 of the heater body 1 when the wick 11 is raised, that part will easily touch the core material 7. Since the wick can be bent, the wick can be raised without any problems. The heater body 1 is detachably fixed to the outer core guide tube 10. Now, when the wick is raised to a predetermined height above the platter by a wick up/down mechanism (not shown) and energized, the heater coil 4 starts to glow red.

On the other hand, kerosene has begun to permeate the core material 7 from the fire wick 12 that has come into contact with it, and eventually the kerosene reaches the heater coil side of the core material 7 and is heated by the heat from the heater coil 4, which is already red hot. vaporize and ignite. Note that a gap A is provided between the heater coil 4 and the core material 7 in order to stabilize the ignition time.

As described above, according to this embodiment, there is no need for a complicated mechanism for moving the ignition heater as in the conventional case, and since the ignition heater is fixed, failures associated with conventional movement are reduced. Furthermore, in the past, since the wick was already impregnated with kerosene, the concentration of vaporized gas was high, and a platinum catalyst was used to raise the heater coil temperature above the red-hot temperature to ignite. According to this method, since kerosene is ignited when it is sucked up into the core material 7, an optimum vaporized gas concentration can be obtained, the temperature of the heater coil can be easily set to red-hot temperature, and its life can be extended. According to the present invention described above, the following effects can be obtained.

(1) Since kerosene is sent to the core material through the wick only when igniting, the mixing degree of the vaporized gas evaporated by heating with the heater coil and air makes it easy to obtain the optimum mixed vaporized gas concentration for ignition. Ignition is guaranteed.

2) Furthermore, as described above, since the optimum mixed vaporized gas is obtained, ignition can be performed without increasing the temperature of the heater coil, and the durability of the heater coil can be improved.

3) Since the heater coil and core material do not move, the structure is simpler and more durable than those that are ignited by movement.
