Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ignition device for a kerosene stove.

Conventional configuration and its problems Conventionally, in this type of ignition device, after raising the wick to the optimum combustion value, the ignition heater was manually brought close to the wick, causing the heater part to become red-hot and igniting. However, as shown in FIG.
Since the lamp moves on the same line as the center line of the lamp wick 12, the distance between the lamp wick 12 and the heater 11 is constant over almost the entire area, making it suitable for ignition under somewhat harsh conditions such as when the room temperature is low or the battery is exhausted. The problem was that the kerosene could not evaporate enough to cause ignition failure.

Purpose of the invention This invention was created in view of these problems.
The purpose is to ensure reliable ignition even under harsh conditions.

Structure of the Invention In order to achieve the above object, the present invention is provided with an ignition heater on a line shifted a certain distance from the center line of the lamp wick, and when the ignition heater approaches the wick, the distance from the left end of the heater to the right end of the wick is different. In this way, the ignition heater is shifted from the center line of the lamp wick by a certain distance in either the left or right direction, and the surface of the ignition heater of a certain length facing the lamp wick is set perpendicular to the center line.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Figure 1 shows a kerosene stove. To ignite the heater, lift up the wick 2 with the wick adjustment knob 1, press the ignition button 3, and bring the ignition heater 4 close to the wick 2, as shown in Figure 2. As shown, the wick 2 is in the tank 5 and contains sufficient oil. As described above, when the ignition button 3 is pressed by hand, the ignition heater 4 is brought closer to the lamp wick 2, and a circuit with the battery 6 is operated (not shown) to cause the ignition heater 4 to become red hot.

The red heat of the ignition heater 4 near the wick evaporates kerosene and ignites the wick 2, but if the amount of evaporation of kerosene is too large or too small relative to the amount of surrounding air, the kerosene will not ignite. In this case, what is important in the process leading to ignition is the distance between the lamp wick 2 and the ignition heater 4. If this distance is too close, the amount of kerosene evaporation tends to increase, while if it is too far away, the amount of kerosene evaporation tends to decrease. However, the optimum dimensions vary depending on changes in room temperature, variations in the heater, battery consumption, etc., so the ignition may or may not ignite slightly. In particular, as shown in FIG. 4, in the conventional ignition device, the distance between the lamp wick and the heater is almost constant over the entire area, making it difficult to respond to the various changes in the conditions described above. Therefore, in this invention, as shown in Fig. 3, the lamp wick 2 is
An ignition heater 4 is provided on a line B shifted by a certain distance D with respect to the center line A. According to this configuration, when the ignition heater 4 is pressed toward the lamp wick, the distance between the ignition heater 4 and the lamp wick 2 will vary sequentially in the range _l1 to _l2 . Therefore, under any conditions, the optimum distance between the ignition heater 4 and the lamp wick 2 can always be obtained, and ignition can be ensured without causing ignition failure. In the figure, 7 is a wick outer cylinder, 8 is a wick guide cylinder, and the lamp wick 2 moves up and down between these two cylinders.

As shown in Fig. 5, the same effect can be obtained by manufacturing the coil 11a of the ignition heater diagonally with respect to the axis, but the coil itself is minute and thin, making it difficult to process, which increases the cost. get high,
In addition, there is a drawback that the defective rate is also high, but the method of the present invention eliminates such problems.

Effects of the invention As detailed above, the ignition system for the kerosene heater of the invention guarantees reliable ignition even under changes in various conditions such as room temperature, coil dimensions, battery consumption (changes in current value), etc. At the same time, the above effects can be achieved with a simple configuration that requires only changing the position of the ignition device, so the cost is also reduced.

Also, since the constant-length surface of the ignition heater that faces the lamp wick is set perpendicular to the center line of the wick, the constant-length surface of the ignition heater is not necessary to change the distance between the ignition heater surface and the lamp wick. Special processing such as tilting the ignition heater can be performed without adding it to the ignition heater, improving productivity.
