JPS5949416A - Wick type kerosene burner - Google Patents

Abstract

PURPOSE:To enable easy reproduction of a burner through cleaning in a way to burn off a kerosene-soaked wick, and to prevent continuous use of the burner in a condition to increase in an exposing quantity, by a method wherein a temporary increase in the maximum exposing quantity of a wick is eliminated through control of operation of a lever, regulating rotation of a gear for vertical movement of the wick, by means of a push button for automatic fire extinguishing. CONSTITUTION:When, during use, a wick 18 is raised, a final tooth 20a of a gear 20 engages with a catching part 21a of a lever 21, and a projection 20b abuts on a contact part 21b to bring it to maximum exposing quantity condition. If, when a kerosene-soaked wick is burnt off or the wick 18 is replaced, a wick reguating knob 14 is turned clockwise as a fire extinguishing button 15 is pushed, the lever 21 is released from engagement, and with the button 15 released from pushing, an incrase in the maximum exposing quantity of the wick 15 is completed. Thereafter with the button 15 pushed downward, the lever 21 is released from engagement, and the wick 18 is lowered to a fire extinguishing positin through the force of a spring 19. When used next time, the maximum exposing quantity is maintained unless the push button is pushed.

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 the conventional example and its problems In the wick of a conventional wick-type oil combustor, such as an kerosene stove, the combustion part 1 was made of flammable cotton cloth, which was made of the same material as the suction part 2, as shown in Figure 1. . 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 the combustion part burns out after the hole 4 is provided, the bottles 6 attached to the wick are sequentially replaced in the upper hole to ensure an appropriate height of exposure of the wick to the combustion chamber. Or, “Da・ka1.”

After non-combustible fibers such as glass fiber were used in the combustion part, it was no longer necessary to leave a large margin in the exposed height or to comb it like the cotton wick mentioned above. However, if you use the th1 phrase for a long time or accidentally use a malicious flame f-'+
6. When used, the fire in combustion section 1 as shown in Figure 2
The area 1a near lle often became clogged with tar, making it impossible to burn and making it unusable.

In such a case, it is possible to raise the wick with a large margin in the exposed height like the cotton wick mentioned above, or change the IN of the wick holder 3 and the wick, but first of all, if the exposed height is large, Regarding the need for extra margin, now that most stoves are equipped with battery-based automatic ignition devices, the disadvantage is that if the exposed height of the wick is too high, the lamp will not ignite.
Even if it were possible to ignite it, the flame would rise very quickly due to the high exposed height, producing a strong odor.Furthermore, if it was burned at the highest exposed height, the flame would rise too high and cause a very strong odor. The situation is dangerous and difficult to implement.

Next, it is not easy to change the position of the wick holder 3 and the lamp wick without lowering the comb, and furthermore, in order to avoid the above trouble when replacing the wick with a new one, insert the pin 5 into the hole of the wick holder 3 from the beginning. The size that should be inserted at the top of 4.

There is no choice but to leave too much leeway in the exposed height of the so-called lamp wick.

OBJECT OF THE INVENTION The present invention has been made in view of the above two problems.It is possible to increase the amount of wick exposure in a lamp so that it can be regenerated by dry cleaning, and to make it possible to use the lamp in a state where the amount of exposure is increased. The purpose is to prevent this from continuing.

Structure of the Invention In order to achieve the above-mentioned object, the present invention removes the restriction means for regulating the maximum amount of exposure of the lamp wick into the combustion chamber for the eleventh purpose, and provides an increasing means for increasing the amount of exposure. The maximum amount of exposure of the lamp wick to the combustion chamber after the lamp is lowered by more than a predetermined length in the extinguishing direction after increasing the amount of exposure of the lamp wick to the combustion chamber by the increasing means is controlled by the regulating means. .

Description of examples The embodiment will be explained below with reference to the drawings.

Figures 3 and 4 show the main parts of a kerosene stove.
8 is a fixed tank, 8 is a cylindrical core outer cylinder, and a cylindrical core 18 is moved up and down through a gap formed by a cylindrical core guide cylinder 9. 1o 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 is a weight that senses vibrations such as earthquakes and activates an anti-seismic automatic fire extinguishing device 13, and the lamp wick 1 is constantly urged downward.
8 instantly to extinguish the fire. 14 is the core adjustment knob,
By turning this, the moon; L, 18 is raised to burn, and by pressing down on the extinguishing button 16, the wick 18
is designed to lower and extinguish the fire. The features of the structure include the seismic automatic fire extinguishing device butt 13 and the gear (FIG. 5, 20) located at the back of the core adjustment knob 14, etc., which will be described in detail later.

16 is an oil filler port into which a cartridge tank 17 is inserted;
The format is now available. Figure 4 shows heat shield plate 1
0 and the state in which the core outer cylinder 8 is removed are shown in 1 to . 18 is the wick,
19 is a spring attached to it which always keeps the wick 18
is biased downward.

FIG. 5 shows the anti-seismic automatic fire extinguishing system 13. The figure shows the normal use, that is, the lamp wick 18 is raised, and the final tooth 20a of the gear 20 is connected to the lever 2.
It engages with the first locking portion 21a. Even if you try to raise the wick 18 any further, the protrusion 20b of the gear 20 will hit the lever 21.
The contact portion 21b cannot be raised further, and at this time the amount of exposure to the upper combustion chamber (FIG. 2A) is the maximum. However, dry firing or wick 1, which will be described later,
8. When replacing the extinguishing button 15, turn the wick adjustment knob 14 to the right while pressing the extinguishing button 15, so that the protrusion 20b passes over the abutting part 21b of the lever 21, and at that point stop pressing the extinguishing button 15. The protrusion 20b then engages with the first engaging part 21a of the lever 21, and the lamp wick 1
8 is completed. The lifting distance (T in Figure 2) is equal to or greater than the distance from the fire pan (6 in Figure 2) to the air hole 23-1 at the bottom of the inner and outer flame tubes 8 and 9 (t in Figure 2). The distance between the final tooth 20a and the protrusion 20b is determined so that

Next, when dry firing or core replacement is completed, press down on the extinguishing button 16 and the protrusion 2 ob and the locking part 2 of the lever 21
1b is released, and the wick 18 is lowered to the extinguishing position by the force of the spring 19. Then, when using the lamp next time, if the normal usage procedure is followed, even if the wick adjustment knob 14 is turned to the right and the wick 18 is raised, the protrusion 20b will hit the abutting part 21b. It has become. Unless the user of Zunawaji has the intention of raising the lamp for dry firing or replacing the wick 18, the lamp will not normally be raised.

Figures 6 to 9 show details of the configuration of the lamp wick 18.
, 24 is a cylindrical ten-piece holding part I2 fixed to the wick burning part 18a, and has a jig engagement protrusion 25 at the upper end, and a cylindrical part fixed to the wick suction part 18b at the lower part. There is a bead 28 and a notch 29 that engage with a protrusion 27 provided on the lower mounting portion 26. At the upper end of the lower receiving part 26, there is a positioning protrusion 3 that matches the jig engagement protrusion 25 at the two ends of the upper mounting member 24 and indicates the position for attaching and detaching the mounting member.
0 is the default.

The combustion part 18a of the lamp wick 18 is attached to both the upper and lower mounting members 24 and 26.
FIG. 7 shows the state in which the suction part 18b is fixed,
The upper and lower mounting members 24 and 26 are connected 19 by engaging the protrusion 27 with the notch 29 through the bead 28, and at the same time complete contact between the combustion part 18a and the suction part 18b. ing. Figure 8 shows the upper and lower mounting members 24.
．． 26 is combined, but here,
18a1 (d) is a traditional knitted fabric mainly made of glass fiber, 18a2 is a paper made of fine ceramic fibers into a paper shape and hardened with a small amount of organic binder / ζ thin plate is used. ing.

FIG. 9 shows a method for attaching and detaching the upper and lower mounting parts 24 and 26 using the jig 31. When you press it in between and turn it in the direction of the arrow, the protrusion 27 will open into the notch 2.
This means that the connection has been made by entering the depths of 9. Such an operation makes it possible to replace only the combustion part 18a of the wick without removing the heat shield plate 10, the wick outer cylinder 8, etc., as long as the jig engagement projection 25 protrudes above the fire pan 6. .

In the above configuration, the exposed height of the lamp wick 18 to the combustion chamber A during normal use is not necessarily higher than 9, so the ignition performance by automatic ignition with batteries is good and the flame rises rapidly. There is no odor, and there is no dangerous excessive flame even when burning at the highest position, resulting in extremely stable combustion.

Even if the lamp wick combustion part 18a near the fire pan becomes tarred and stops burning due to long-term use or mistaken use of a bad fuel, it can be easily fixed. By lifting up the area near the tar-filled fire pan to a height higher than the air hole 23 at the bottom of the inner and outer flame cylinders, it is possible to remove tar almost completely. .

In addition, the higher the position of the area near the fire pan where tar has grown during an empty furnace, the higher the air supply, the better the air supply, and the more complete the removal of tar, but it is the same as the air hole 23. There is no big difference as long as the height is higher. However, air hole 2
Below 3, the tar removal rate drops rapidly.

In fact, in the configuration of a device equipped with a conventional anti-seismic automatic fire extinguishing system, the gear 20 has a protrusion 20b, and the lever 21 has a contact part 21.
This configuration can be achieved by simply providing b), and it can be very inexpensively and quickly transitioned to homiso (installation of an anti-earthquake automatic fire extinguishing system is currently mandatory).

Next, by using a paper-like thin plate made of fine ceramic fibers in the wick combustion part 18a, the removal of tar by air heating is made more complete, and the service life is extremely extended due to its excellent heat resistance. I was able to do that. In other words, the capillary tubes of fine ceramic fibers made into a paper-like paper are very small and have many spaces (capillaries), so there is no break in the capillary action of the oil, so the oil can spread through the water bowl. As a result, it has a very high oil content. Therefore, once the oil has been sucked up, it will contain plenty of oil, but since there is no space, tar will form inside.
Even if it does occur, it will occur on the surface of the thin plate, so it will be removed by air-burning, and if the Yazuku wick 18 is lowered and air-burned, the effect will be greater, and it has very good heat resistance compared to glass fiber. This means that the lamp will not wear out no matter how many times you run the furnace over and over again.As mentioned above, in combination with raising the wick to a height of 18, the lamp will have an extremely long life.

In addition, in a case where the lamp wick 18 is divided into upper and lower halves, if the lamp wick combustion part 18a can be replaced without disassembling the appliance, it is necessary that the jig engagement protrusion 26 is located above the fire pan 6. It is possible, but if you do so, use a hot plate 6
Since tar tends to adhere to the upper end of the upper and lower mounting members 24 and 26 that protrude further upwards, making it impossible to move the wick up and down, until now only a small portion of the upper end of the upper and lower mounting members 24 and 26, such as the jig engagement protrusion 26, has been installed above the fire pan 6. However, there was still a problem in that tar easily adhered to the protrusion 26. This embodiment also solves this problem. That is, even when the lamp wick exposure height is maximized during normal use, the jig engagement protrusion 26 is located below the fire pan 6, and the projection 26 protrudes beyond the fire pan 6 by lifting up only when replacing the wick. That's what I did. By doing so, there will be no possibility that tar will adhere to the protrusion 25 and the lamp wick 18 will not be able to move up and down, and since there is no tar attached around the protrusion 25, it will be easier to engage the jig 31 with the protrusion 26. It is easy to use, and in addition, during normal use, the upper end of the upper and lower mounting members 24.26 is lower than the upper end of the upper and lower mounting members 24.2 as before.
It no longer happens that tar flows into the gap between the parts 6 and 6, making it impossible to attach and detach them.

Effects of the Invention According to the present invention, during normal use, the maximum amount of exposure to the ignition odor is increased and the oven is air-burned, tar is almost completely removed, and subsequent combustion can be stabilized.

Power for empty furnaces etc. as mentioned above] Dew of the core (J, S
Even if fA: is increased, once the wick is moved more than a predetermined amount in the extinguishing direction, the maximum exposure of the wick will be reduced by the regulating means, and combustion will continue in an unnatural state. Not at all.
