Description

FIELD OF THE INVENTION [0001] The present invention relates to a portable oil burner capable of controlling combustion,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a burner capable of controlling combustion, and more particularly, to a portable oil burner that is widely used for mountaineering or fishing, in which combustion is controlled automatically according to thermal power, .

Portable burners are widely used when outdoor activities such as mountain climbing or fishing require firepower for cooking. Recently, disposable butane gas cylinders, which are convenient to use, are widely used. However, there is a problem that the pressure vessel must be treated as a by-product after the use, and the amount of heat is not large and the risk of explosion can not be excluded. On the other hand, there is a portable type burner in which a fuel cell is provided on its own, and this fuel cell is filled with petroleum (kerosene, hereinafter the same) and vaporized. This oil burner is inconvenient to use, but it is still favored by professionals because it has good firepower, does not emit waste, is environmentally friendly, and can reduce the volume of the burner itself.

On the other hand, conventional petroleum burners are more difficult to handle than gas burners for beginners. Especially, it was very limited to adjust the firepower because the firepower can be adjusted only through the air pressure. So, if you have to use a weak fire at the end of cooking rice, the existing oil burner may be easily turned off and only soot is generated. On the contrary, when a strong fire is used, the fire is so strong that the amount of heat used for the actual heating is small, and a large amount of the heat is dissipated to the outside.

As for the current status of domestic patent application regarding the burner relating to the adjustment of the thermal power or the combustion state, it is known that the gas burner is the same as the patent application No. 10-2008-0048982, No. 20-2007-0019701, No. 10-2003-0018024 There is only.

An object of the present invention is to provide a portable oil burner capable of automatically controlling a combustion state. And more specifically, to provide a portable type oil burner capable of generating flames stably regardless of the intensity of fire, thereby preventing soot and further eliminating waste of fuel.

The above objects are accomplished by a fuel cell in which an air injection pump and a fuel injection port are installed and a vaporized fuel discharge port is provided so that vaporized fuel can be discharged to the upper side; A nozzle connected to the vaporizing fuel discharge port through a vaporizing tube and installed in the upper part of the fuel cell; An upper plate fixed to an upper portion of the nozzle; And a tripple for supporting the cooking vessel so that the cooking vessel can be positioned on the upper portion of the nozzle, the portable oil burner comprising:

A main pipe fitted to an outer periphery of the nozzle and having a thread on an outer peripheral surface thereof; A bottom plate, a side wall, and an upper plate. The bottom plate has a center hole passing through the center of the bottom plate. The main plate is fixed to the main pipe by main pipe fixing means. Wherein the flame inducing body includes a flame inducing body in which a gas ejecting hole is formed in various directions so that the vaporizing gas ejected from the combustion chamber can be ejected outward in various directions.

According to an aspect of the present invention, a first gas ejection hole may be provided in a bottom plate of the flame induction enclosure, and a second gas ejection hole may be formed in the side wall along the circumferential direction of the side wall.

According to another aspect of the present invention, the main pipe fixing means may be a female screw portion provided in the center hole of the bottom plate.

According to another aspect of the present invention, the apparatus may further include an intermediate cap provided with a through hole through which the main pipe passes, and an intermediate cap inserted into the main pipe in a dome shape and seated on the bottom plate.

According to another aspect of the present invention, the first gas ejection hole may be provided in a downward slanting direction between a horizontal direction and a vertical direction.

According to the above configuration, the flame inducing enclosure ejects the vaporizing gas in the downward direction or the downward inclining direction, so that it gradually heats from below the flame induction enclosure of the petroleum burner during ignition. Therefore, when the amount of the vaporized gas is small due to the low pressure, misfire or soot generated due to a low temperature of the flame inducing enclosure can be prevented. When the pressure is high, the vaporizing gas is ejected in various directions to disperse the ejecting direction of the flame, thereby preventing the flame from being ejected to the outside of the cooking container, thereby preventing waste of fuel and enabling stable combustion. And the size of the flame is automatically controlled according to the pressure inside the fuel cell.

2 is an exploded perspective view of the main part of the flame induction enclosure of the combustion adjustable oil burner shown in Fig.
Fig. 3 is a longitudinal sectional view of Fig. 2. Fig.
4 is a sectional view similar to Fig. 3 according to another embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The basic configuration of the petroleum burner will be described with reference to FIG. 1 and then with reference to FIG. 2 to FIG. 4 in order.

The scope of the present invention should not be construed to be limited by the petroleum burner of the type shown in FIG. 1 because various types of petroleum burners are actually provided. It should be noted that the oil burner of Figure 1 is merely illustrative of a well-known type of petroleum burner.

The fuel tank 10 is provided with an air injection pump 11 and a fuel injection port cap 12. A vaporizing fuel outlet is provided at an upper portion of the fuel cell 10 so that vaporized fuel can be discharged.

Three leg fixation tubes 13 are normally fixed along the circumferential direction of the fuel cell 10 by welding and the leg fixation tube 13 is fitted with a trivet 14 whose upper end is bent in the form of a translator. The trivet 14 serves both as a leg of the oil burner and as a cradle for mounting the cooking vessel (not shown).

The vaporizing fuel outlet is connected to the vaporizing tube 20 so that the vaporized fuel rises upward along the vaporizing tube 20. A vaporizing dish 30 for heating the vaporizing tube 20 by promoting vaporization by ignition in a state containing a small amount of fuel is installed on the upper portion of the fuel cell 10. [

The nozzle (32) is fixed to the vaporizing tube (20) so as to spray vaporized gas upward. A known upper plate 33 is fixed to the upper portion of the nozzle 32. The flame inducing enclosure 40, which is the subject of the present invention, is installed at the upper end of the vaporizing tube 20. [ The preheating tube 31 having a triangular structure is a tube for supporting the upper dish 33 and vaporizing the fuel while passing the fuel. When the small amount of fuel contained in the vaporizing dish 30 is burned, the preheating tube 31 is heated and the fuel is vaporized to eject the vaporizing gas through the vaporizing tube 20 and the nozzle 32 installed on the vaporizing tube. The ejection pressure of the vaporized gas is proportional to the pressure inside the fuel cell (10).

Hereinafter, a nozzle assembly 40, which is a core of the present invention, will be described. The nozzle assembly includes a flame induction enclosure (50) and a main tube (60). The nozzle assembly 40 may be introduced by a petroleum burner manufacturer and provided as an accessory, or may be purchased and used separately by the petroleum burner owner. That is, the nozzle assembly 40 may be separately distributed independently of the petroleum burner.

The main pipe (60) is fitted on the outer periphery of the nozzle (32), and a screw thread (61) is provided on the outer peripheral surface. In the lower portion of the main pipe (60), a fitting hole (62) is formed laterally along the circumferential direction. The insertion hole 62 is for rotating the main pipe 60 using a pointed tool as described later.

The flame induction enclosure 50 is provided with a bottom plate 51, a side wall 52 and an upper plate 53 so that a space is provided therein. The bottom plate 51 is in the form of a disk and is in the form of an upper plate 53 or a flat plate. The side wall 52 and the upper plate 53 are integrally formed, and they are closely fitted into the bottom plate 51 and assembled, thereby forming the flame inducing housing 50. In some cases, the bottom plate and the side wall are integrally provided, and the upper plate is coupled to the bottom plate. In the drawings, the upper plate 53 is shown as a flat plate but may be curved in a dome shape. As shown, the bottom plate 51 is formed with a jaw at the edge thereof and the lower end of the side wall 52 is fitted into the jaw. However, this is an example, and may be screwed or bolted.

A center hole 511 through which the main tube 60 passes is provided at the center of the bottom plate 51. The bottom plate (51) is fixed to the main tube (60) by the main tube fixing means. The main pipe fixing means is a female screw portion 512 provided in the center hole 511 of the bottom plate 51. On the bottom surface of the bottom plate 51, pedestals 514 and 515 are protruded so that the flame inducing enclosure 50 can be stably mounted on the upper plate 33. The pedestals 514 and 515 may be changed in shape from the shape of the upper plate 33 to the specific shape of the upper plate 33,

3, the vaporized gas sprayed upward from the nozzle 32 through the main tube 60 is diffused into the inner space of the flame induction enclosure 50. As shown in FIG.

The flame inducing housing (50) is formed with a plurality of gas jet holes in various directions so that the vaporized gas can be ejected to the outside through various directions. A first gas ejection hole 513 is provided in the bottom plate 51 of the flame induction housing 50 in the vertical direction and a plurality of second gas ejection holes 51 are formed in the side wall 52 along the circumferential direction of the side wall 52 521 may be provided (see FIG. 3). The first gas ejection holes 513 are provided by drilling along the edges of the bottom plate 51, that is, at right angles along the circumferential direction at regular intervals.

According to another embodiment of the present invention, the first gas ejection hole 513 may be provided in a downward sloping direction between the horizontal direction and the vertical direction as shown in Figure 4. The slope angle A is 45 . It is good enough. Furthermore, the first gas ejection holes 513 provided along the circumferential direction of the support plate 51 can have various inclination angles A, respectively. For example, 30 1 for group 1, 45 은 for group 2, and 60 3 for group 3.

According to another embodiment of the present invention, a through hole 71 through which a main pipe can pass is provided at the center, and an intermediate cap 70 (see FIG. 1), which is fitted to the main pipe 60 in a dome- May be optionally included. As shown in Fig. 3, the upper end portion 60a of the main pipe rises higher than the intermediate cap 70. As shown in Fig. The user can adjust the height of the main pipe 60 by using the fitting hole 62 even during use of the oil burner. The combustion condition or the gas jetting condition can be changed according to the height of the main pipe 60. This allows us to find the desired combustion conditions in various environments.
