Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a wick type oil burner such as an oil stove.

Structure of conventional examples and their problems As shown in Figure 1, in the wick of a conventional wick-type oil combustor, such as an kerosene stove, the combustion part 1 was made of flammable cotton fabric, which was made of the same material as the suction part 2. . In such a case, the combustion part 1 of the wick burns out quickly, so the highest point of the wick exposed to the combustion chamber is made extremely high to provide some margin for burnout, or the wick holder 3 is used to raise it up. If a hole 4 is provided and the combustion part burns out, the pins 5 attached to the wick are sequentially replaced with the upper holes to ensure a proper exposure height of the wick to the combustion chamber. Was.

However, since non-combustible fibers such as glass fibers were used in the combustion part, it is no longer necessary to leave a large amount of leeway in the exposed height or to roll up the wick, as with the cotton wick mentioned above. However, if such a fuel is used for a long time or if bad fuel is mistakenly used, the area 1a of the combustion part 1 near the fire pan 6 will become clogged with tar and become unusable, as shown in Figure 2. It was very warm.

In such a case, it is possible to give a large margin to the exposed height like the cotton wick mentioned above, or to raise the wick by changing the position of the wick holder 3 and the wick, but first, leave a large margin in the exposed height. As for battery-powered automatic ignition devices, which are now common in most stoves, there is a drawback that if the exposed height of the lamp wick is too high, it will not ignite, and even if it can be ignited, the flame will be It is difficult to carry out this process because the rise of the flame is rapid and produces a strong odor, and furthermore, if it is burned at the highest exposed height, the flame will burn too high and rise high, creating a very dangerous situation.

The next method is to change the position of the wick holder 3 and the lamp wick and hang it down, but in order to do so, the device must be disassembled, which is time-consuming, and it is not something that anyone can do easily. Furthermore, in order to save the above-mentioned trouble when replacing the wick with a new one, it is necessary to insert the pin 5 into the top of the hole 4 of the wick holder 3 from the beginning, leaving a large margin in the exposed height of the wick. .

Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and anyone can easily and temporarily reduce the amount of exposure of the wick when the lamp wick becomes unusable due to tar clogging near the fire pan of the wick combustion part. The purpose of this is to increase the amount of exposure so that it can be regenerated by dry cleaning, and to prevent continued use in this state of increased exposure.

Structure of the Invention In order to achieve the above-mentioned object, the present invention temporarily releases the regulating means that regulates the maximum amount of exposure of the lamp wick to the combustion chamber, and provides an increasing means for increasing the amount of exposure. The maximum exposure amount of the lamp wick to the combustion chamber after the lamp wick is lowered by more than a predetermined amount in the extinguishing direction after increasing the exposure amount of the lamp wick to the combustion chamber by the means is configured to be controlled by the regulating means.

Description of examples Examples thereof will be described below with reference to the drawings.

Figures 3 and 4 show the main parts of a kerosene stove, where 7 is a fixed tank, 8 is a cylindrical wick outer tube, and the gap formed by the cylindrical wick guide tube 9 is the cylindrical wick. 18 is designed to move up and down. 10 is a heat shield plate, and 11 is a lighting heater, which serves to ignite the lamp wick 18 using a dry battery as a power source.

Reference numeral 12 denotes a weight which detects vibrations such as earthquakes and activates the anti-seismic automatic fire extinguishing device 13, which instantly lowers the lamp wick 18, which is always urged downward, to extinguish the fire. 1
Reference numeral 4 denotes a wick adjustment knob, and by turning this knob, the wick 18 is raised to cause combustion, and by pressing down on the extinguishing button 15, the wick 18 is lowered to extinguish the fire. The features of the structure include the anti-seismic automatic fire extinguishing device 13 and the gear (FIG. 5, 20) located at the back of the wick adjustment knob 14, which will be described in detail later. 16 is an oil filler port, and cartridge tank 1
7 is inserted and fuel is supplied. FIG. 4 shows a state in which the heat shield plate 10 and the wick outer cylinder 8 have been removed, and the lamp wick 18 is a lamp wick, and the lamp wick 18 is constantly urged downward by a spring attached to the lamp 19. FIG. 5 shows the anti-seismic automatic fire extinguishing system 13. The figure shows the state in which the wick 18 is raised during normal use, and the final tooth 20a of the gear 20 is engaged with the lever 21. It is engaged with the portion 21a. Even if you try to raise the wick 18 further, the protrusion 20b of the gear 20 will hit the contact part 2 of the lever 21.
1b and cannot be raised, and this is when the maximum amount of exposure to the upper combustion chamber (Fig. 2A) occurs. However, when dry burning or replacing the wick 18, which will be described later, by turning the wick adjustment knob 14 to the right while pressing the extinguishing button 15, the protrusion 20b can pass over the contact part 21b of the lever 21 without hitting it. If you stop pressing the fire extinguishing button 15 at that point, the protrusion 20b will now move to the lever 2.
1, and lifting up of the lamp wick 18 is completed. In addition, the raising amount (T in Figure 2) is from the fire pan (6 in Figure 2) to the inner and outer flame tubes 8,
9. Connect the final tooth 20a and the protrusion 20 so that the distance is equal to or greater than the distance to the lowest air hole 23 (Fig. 2 t).
The distance from b is determined.

Next, when dry firing or wick replacement is completed, pushing down the extinguishing button 15 releases the engagement between the protrusion 20b and the locking part 21b of the lever 21, and the wick 1
8 is lowered to the extinguishing position by the force of the spring 19.
When the lamp is used next time, if the normal usage procedure is followed, even if the wick adjustment knob 14 is turned to the right to raise the wick 18, the protrusion 20b will come into contact with the abutment part 21b, so that the lamp will not be lifted up. There is. In other words, unless the user has the intention of lifting the lamp for dry firing or replacing the wick 18, the lamp is not normally lifted.

In the above configuration, the exposed height of the lamp wick 18 to the combustion chamber A during normal use does not become higher than necessary, so the ignition performance by automatic ignition with batteries is good, and the flame rises quickly. There is little odor because it does not burn, and even if it is burned at the highest position, there will be no dangerous excessive flames, resulting in extremely stable combustion.

Even if the area near the fire plate of the wick combustion part 18a becomes clogged with tar due to long-term use or incorrect use of bad fuel, anyone can easily carry out the lifting operation. Therefore, by raising the area near the fire pan where tar has accumulated to a height higher than the air hole 23 at the bottom of the inner and outer flame tubes and performing dry firing, it becomes possible to almost completely remove tar. Note that the higher the position of the area near the fire pan where tar accumulates during dry firing, the higher the air hole 23, the better the air supply and the more complete the removal of tar. If it's more than that, there's no big difference. However, below the air hole 23, the tar removal rate decreases rapidly.

In addition, in the configuration of a device equipped with a conventional anti-seismic automatic fire extinguishing device, a protrusion 20b is provided on the gear 20, and a lever 2 is provided on the gear 20.
This configuration can be achieved by simply providing the abutment portion 21b on the 1, and can be mass-produced at a very low cost (currently, the installation of an anti-seismic automatic fire extinguishing system is mandatory).

Effects of the Invention According to the present invention, stable combustion with little ignition odor can be obtained during normal use, and even if tar is generated in the wick, anyone can easily increase the maximum amount of exposure of the wick to the combustion chamber. The tar is almost completely removed by dry firing, and subsequent combustion can be stabilized.

Furthermore, even if the exposure amount of the wick is increased due to dry firing, etc. as mentioned above, once the wick is moved more than a predetermined amount in the extinguishing direction, the maximum exposure amount of the wick will be controlled by the regulation means, resulting in an unnatural state. The combustion will not continue.

Furthermore, the present invention is constructed using gears, levers, and buttons, so it is not only possible to set the wick height to any desired position and adjust the combustion amount, but also to quickly lower the wick and extinguish the fire with a single button operation. It is easy to operate, and since these components are used to achieve the above-mentioned effects, the structure can be simplified.
