Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an oil combustor with an improved wick structure.

[Technical background of the invention and its problems]

BACKGROUND OF THE INVENTION Many oil combustors have a structure in which a wick sucks up fuel in an oil tank and burns it in a combustion tube installed on a burner basket. The above-mentioned lamp wick used in such an oil combustor is generally constructed as follows.

That is, the wick body of the lamp wick has a cylindrical shape and is divided into upper and lower halves. The lower core body functions to suck up the fuel in the oil tank, and is generally made of vertically woven fibers such as cotton or polyester, or made of felt. On the other hand, the upper core body is made of heat-resistant glass fiber, carbon fiber, etc., and functions to evaporate the fuel. These upper wick bodies and lower wick bodies are then joined together to form a lamp wick.

This lamp wick is attached to the outer peripheral surface of a cylindrical wick guide so as to be movable up and down. Further, a metal wick holder is integrally provided on the outer peripheral surface of the lower part of the lamp wick. The rack, which is integrally provided on the core holder, is moved up and down by engagement with a pinion that is rotationally driven by an operation dial, and the burner basket, which is disposed concentrically with the core guide, protrudes from the upper surface of the burner basket. The amount of combustion is adjusted by the burner, and the fire is extinguished by lowering the upper end of the wick from the upper surface of the burner basket.

Such vertical movement of the wick must be performed reliably, and for this purpose, it is necessary to improve dimensional accuracy. To do this, you can cut a nail on the inside of the wick holder to integrate it with the wick, or attach a paper or cloth cloth to the outside or inside of the wick, or both, so that the wick holder and the wick are integrated. It is necessary to measure adhesion. In this case, the installation width of the cross (width along the vertical direction of the wick) should be as much as possible.
It is preferable to apply it over the entire surface of the wick, from the top to the bottom, as this will ensure that the wick will slide more securely. However, since the cloth is combustible, it must be attached at a certain distance from the tip of the combustion part, and the upper side of the cloth in the attached state is located below the upper end of the lamp wick.

As described above, the lamp wick configured in this manner has a cylindrical shape and is installed in the outer circumferential surface of the wick guide so as to be movable up and down. At present, it is almost impossible for the work of assembling the device into the device to be carried out consistently, and as a result, the following problems arise.
In other words, the wick, which consists of a cloth attached to the wick body, is manufactured individually and transported to the point where it is assembled into a device.In order to improve transportation efficiency, the cylindrical wick is separated in its diametrical direction. It is folded into a flat shape. Of course, it is returned to the cylindrical shape when it is assembled into the fixture, but the folded part, that is, the two diametrically opposed places on the outer circumferential surface of the lamp wick, has a folding habit, and when it is returned to the cylindrical shape, that part The cloth may separate from the outer surface of the core body. If such peeling occurs, it will prevent the wick from rising during use.

FIGS. 1 and 2 illustrate the above-mentioned problems. In the figure, 11 is a lamp wick, which connects an upper wick body 12 and a lower wick body 13, and has a cross 14 attached to its outer peripheral surface. In this case, the cloth 14 does not completely surround the outer peripheral surface of the lamp wick 11, but leaves a portion 11a where the cloth is not attached in a part of the lamp wick 11. When folding into the shape of a flat plate, this cloth non-applied portion 11a is used, but folding grooves are formed at two locations, this portion and the portion diametrically opposed thereto, as described above. For this reason, when the cloth 14 is returned to a cylindrical shape, a peeled portion 14a of the cloth 14 due to folding may occur in a portion diametrically opposed to the cloth non-applied portion 11a, as shown in FIG. Since the lamp wick 11 is folded using the cloth non-attached part 11a, only one peeling part 14a is required, but in order to prevent the cross non-attached part 11a from occurring,
When the cloth 14 is pasted so as to completely surround the lower outer circumferential surface of the lamp wick 11, peeling portions 14a may occur at two diametrically opposed locations due to folding.

The above-mentioned lamp wick 11 is the first
As shown in the figure, the lead holder 15 is integrally attached to the outer periphery of the lower part, and then attached to the outer circumferential surface of the cylindrical lead guide 16 so as to be movable up and down. The core guide 16 passes through and rises between the burner basket 18 provided on the tank 17, and its upper end protrudes from the upper surface of the burner basket 18.

However, in this case, if the above-mentioned peeled part 14a of the cross 14 exists, it will get stuck on the lower shoulder part 18a of the burner basket 18 during the lifting operation, causing the problem that the lamp wick 11 cannot be raised to a predetermined height. arise.

[Purpose of invention]

An object of the present invention is to provide an oil combustor which prevents the separation of the cloth due to folding and reliably prevents the wick from being unable to rise.

[Summary of the idea]

The present invention relates to an oil combustor that uses a wick to draw up fuel from an oil tank and burn it.The wick consists of a cylindrical wick body and a cloth attached to the outer circumference of the wick body. Lower than the top side of the cross of the core body in the state,
In addition, by setting the shape of the cross so that the cross is not located at least above the two parts facing each other in the diametrical direction, it is possible to prevent the occurrence of a peeling part at the top of the cross due to folding before assembling, and after assembling. This prevents the wick from being unable to rise.

[Example of idea]

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings.

Figure 3 shows the schematic configuration of the oil combustor.
The lamp wick 11 is vertically movably supported on the outer periphery of a cylindrical wick guide 16, as in the conventional case. The lower end of the oil tank 1 is integrated with the core guide 16.
7, and its upper end projects above the burner basket 18 through a space between the oil tank 17 and a burner basket 18 integrally provided with the oil tank 17. In addition, a wick holder 1 is integrally fixed to the lower outer periphery of the lamp wick 11.
Reference numeral 5 has a rack gear, and the lamp wick 11 is moved up and down by meshing with the rotating shaft of the wick lifting dial 20 and an integral pinion gear. A combustion tube 21 is placed on the burner basket 18 and burns the fuel supplied from the lamp wick 11 together with combustion air.

As shown in FIG. 4 or 5, the lamp wick 11 has a cross 24 attached to the outer peripheral surface of a cylindrical wick main body 23 at a constant distance from the upper end thereof. Here, Figure 4 shows the cross 2
4. A case is shown in which the cross is pasted so as to completely surround the outer circumference of the lamp wick 11, and FIG. Indicate the case. In addition, the core body 2
3 is the same as the upper core body 12 and lower core body 13 sewn together shown in FIG.

Here, in the present invention, at least the upper part of the core main body 23 in the cross-attached state is lower than the upper side of the cloth 24 and is opposite to each other in the diametrical direction.
That is, the cross 24 is shaped so that it is not located in the parts indicated by 23a and 23b in FIG. 4, and above the reference numeral 11a in FIG. is set. For this reason, as for what is shown in FIG.
A V-shaped deleted portion 24a is provided at a portion corresponding to b.
In addition, for the one shown in Fig. 5, the cross 24
A V-shaped deletion portion 24 is provided at the portion corresponding to the reference numeral 23a.
Provide a.

In the above configuration, when the lamp wick 11 is lowered (extinguished), the vertical overlap between the lamp wick 11 and the inner peripheral surface of the burner basket 18 is generally 10 to 20 mm. In addition, the cross 2 attached to the lamp wick 11
The upper side of 4 is at least 20 mm from the upper end of the wick 11.
Located at least 25mm apart. If the upper side of the cloth 24 is located at a position smaller than the above dimension, the cloth 24 will discolor or soften due to the influence of heat, so the above dimensional relationship is reliably maintained. Therefore, in the lowered position of the lamp wick 11, the upper side of the cross 24 is located below the lower shoulder 18a of the burner basket 18.

When folding the lamp wick 11 for transportation, etc., fold the parts 23a and 23b in the case of FIG. 4 in the vertical direction, and the parts 23a and 11a in the case of FIG. and fold it into a flat shape. In this way, the cloth 24 does not peel off in other parts and remains in a good adhesion state. Therefore, the lamp wick 11 rises smoothly without being caught by the lower shoulder 18a of the burner basket 18. That is, the bent portions 23a, 23b or 2
Since the cross 24 is not located at 3a and 11a,
When rising, it does not hit the shoulder 18a of the burner basket 18. Further, even if the lower end top portion of the V-shaped cut portion 24a is peeled off, since it is cut in a V shape, it contacts the lower shoulder portion of the burner basket 18 in a tapered shape. In other words, the contact at this part is a point contact and works to press the lower end apex of the V-shaped removed part 24a against the lamp wick 11, so this part does not get caught in the lower shoulder of the burner basket 18, and the lamp wick 11 moves smoothly. Rise.

[Effect of idea]

As described above, according to the present invention, the folding wrinkles before the lamp wick is installed are prevented from occurring on the upper side of the cloth attached to the outer periphery of the lamp wick. The peeled part of the upper side of the cloth due to the curls does not catch on the lower shoulder of the burner basket, and the wick can be moved up and down smoothly.
