Description

Portable gas burner

The present invention relates to a portable gas burner, and more particularly, to a portable burner using gas as a fuel, which is hardly influenced by wind and is capable of achieving smooth combustion even in a high temperature region or a low temperature, And to a device that can maximize the convenience and the merchantability of the product.

Generally, a burner refers to a cooking device that mixes a gas or a liquid fuel with air and burns it. Depending on the type of fuel, there are a gas burner, a petroleum burner, an alcohol burner, and the like.

Particularly, a portable burner is a product that improves mobility and portability by reducing volume, and burners using oil or gas as fuel are the most widely used.

First, portable petroleum burners using petroleum as fuel can be used in a high altitude environment or a low temperature environment and have advantages of high firepower. However, since the volume is relatively large and heavy, and pumping for gasoline and compression is repeated, And it was difficult for an expert to use it easily.

In contrast, a portable gas burner using gas, especially butane gas as a fuel, is smaller in volume and lighter than the portable petroleum burner described above, and is particularly advantageous in that it can be easily used by unskilled persons because the gas can be easily replaced.

FIG. 1 is a perspective view showing a conventional portable gas burner, and FIG. 2 is a front sectional view of a recess in a conventional portable gas burner.

1 and 2, a conventional portable gas burner is burned in the head 20 when gas as a fuel is supplied from the gas cylinder 10, and a preheating tube 30 is placed in the middle of the fuel supply tube The gas supplied to the head 20 is preheated.

However, in the conventional portable gas burner, the head 20 in which the combustion is performed is exposed to the outside as it is, so that it is greatly influenced by wind.

As a result, when a portable gas burner is used in a windy place, the initial ignition is not easily performed. Even if the ignition is performed, the influence of the wind is greatly exerted and the thermal power is remarkably reduced.

In addition, although the preheating tube 30 for preheating the fuel supplied to the head 20 in a low temperature state is provided, since the preheating tube 30 is also directly exposed to the outside, There has been a problem in the prior art that the function is not properly performed due to the influence of wind or low temperature.

The wall surface of the body 100 may have a sloping plane, but it is preferable that the wall surface of the body 100 is bent in a multistage manner in view of rigidity and the like.

On the wall surface of the body 100, a plurality of outer through holes 110 are formed to penetrate radially equally.

In the figure, two upper and lower outer through holes 110 are arranged at three positions with a phase angle difference of 120 degrees so that a total of six outer through holes 110 are formed in one body 100.

When the area of the outer through hole 110 is large, the amount of air to be supplied is increased. However, when the outer air hole 110 has a large area, If the area is small, the amount of air to be supplied is small, but it is not influenced by the outside wind, so that the thermal power of the portable gas burner of the present invention is greatly affected.

Next, the support leg 200 is formed by bending or perforating a metal plate having a predetermined thickness. Preferably, three support legs 200 are rotatably fixed to the bottom surface of the body 100.

Accordingly, when the portable gas burner of the present invention is used, the support leg 200 can be opened with a phase angle difference of about 120 degrees as shown in FIG. 5 (a), and when it is not used, It is possible to minimize the volume.

4, it is preferable that a plurality of through holes 210 are formed in the support leg 200 so as not to affect the rigidity, thereby reducing the weight.

The lower portion of the support leg 200 is extended to support the ground, and at this time, it is preferable to increase the contact area with a part of the support leg 200 when it is bent horizontally so as to be parallel to the ground.

In addition, the upper portion of the opposite side may be extended to seat a cooking container or the like, and a plurality of slant projections 220 may be formed to prevent the cooking utensil placed on the support leg 200 from slipping.

At this time, if the support leg 200 is formed into a bird's head shape as shown in FIG.

Next, the gas nozzle 300 is connected to a central bottom surface of the body 100 to generate a flame by burning the supplied gas.

4, the gas nozzle 300 includes a body 310 that is screwed to the body 100 in a substantially hollow cylindrical shape, and a hole for injecting a gas at the center thereof. The gas nozzle 300 is coupled to the upper end of the body 310, (Not shown).

Accordingly, when the gas is supplied into the body 310 of the gas nozzle 300, the gas is burned out through the hole formed in the upper head 320.

At this time, the body 310 and the head 320 are separately formed as shown in FIG. 4, thereby separating the head 320 from the body 310 and cleaning the inside thereof.

Therefore, even if the food being cooked during use of the portable gas burner of the present invention overflows from the cooking container and the gas nozzle 300 is contaminated, for example, the hole of the head 320 is clogged, the body 310 and the head 320 Can be separated from each other and cleaned easily.

Next, the preheating socket 400, which is the core of the present invention, is positioned inside the body 100 with a predetermined gap, for example, a gap of about 1 cm, and is formed to be slightly smaller than the body 100 do.

The preheating socket 400 also has the shape of a concave container of a metal material. A step 410 is formed in the middle of the wall, and the upper side of the preheating socket 400 has a funnel shape with respect to the step 410, And the lower side of the step 410 is formed into a cylindrical shape having a constant diameter.

The upper side of the step 410 of the preheating socket 400 smoothly surrounds the flame burned from the gas nozzle 300.

A plurality of inner through holes 420 are formed at equal radial intervals at a lower side of the step 410 of the preheating socket 400.

In the drawing, the inner through hole 420 has four inner through holes 420 formed in one preheating socket 400 with a phase angle difference of 90 degrees.

When the area of the inner through hole 420 is large, the amount of air to be supplied is increased. However, since the amount of air supplied to the outside of the preheating socket 400 is large, The amount of air to be supplied is small when the area is small, but is not affected by the outside wind. Therefore, the thermal conductivity of the portable gas burner of the present invention, together with the above- do.

A hole is formed at the center of the bottom surface of the preheating socket 400 and is screwed and fixed to the outer peripheral surface of the upper end of the body 310 of the gas nozzle 300.

As a result, when the portable gas burner of the present invention is used, the preheating socket 400 is maintained in a red state by the combustion of gas.

A flame radiation plate 500 is installed at the center of the upper inlet of the preheating socket 400 and the height of the flame radiation plate 500 is somewhat lower than the upper end of the preheating socket 400.

The flame radiation plate 500 is a plate having a substantially concave shape and is supported by a plurality of spokes 510 at the outer periphery of the inlet of the preheating socket 400.

In the figure, four spokes 510 are extended from the flame radiation plate 500 with a phase angle difference of 90 degrees.

The flame radiation plate 500 serves to spread the flame of the gas discharged from the gas nozzle 300 uniformly in all directions.

As shown in FIG. 6, one end of the hollow pipe is connected to the gas cylinder 900, and the other end is connected to the body 310 of the gas nozzle 300 So that the gas in the gas container 900 is supplied to the gas nozzle 300.

Particularly, in the present invention, the preheating pipe 600 does not merely supply the gas to the gas nozzle 300, but also serves to preheat the gas supplied to the gas nozzle 300 to a high temperature.

For this, the preheating tube 600 is directly connected to the body 100 through the body 100 without passing through the body 100 and directly connected to the gas nozzle 300, And is bent in a substantially "? &Quot;

As a result, since the gas supplied to the gas nozzle 300 can be preheated to a high temperature, a high thermal power can be obtained. Particularly, the preheating tube 600 is not exposed to the outside, 100 and the preheating socket 400, it is possible to perform preheating with high efficiency at all times without being influenced by external temperature or wind.

Particularly, the present applicant has found that the portable gas burner according to the present invention can be used even in the case where the size of the above-mentioned components, for example, the size of the body 100 And the cross sectional area of the inner through hole 420 formed in the preheating socket 400 were changed. The test was repeated while varying the cross sectional area of the outer through hole 110 formed in the preheating socket 400 and the cross sectional area of the inner through hole 420 formed in the preheating socket 400.

As a result, the inner vent hole 420 is formed below the step 410 of the preheating socket 400, and the preheating tube 600 is passed through the space between the body 100 and the preheating socket 400 Shaped bottom bend portion corresponds to the gas nozzle 300 and the uppermost height reaches the upper end of the preheating socket 400. The '?'

In this state, if the ignition device 810 is pressed, spark is generated in the flame generator 830 through the lead wire 820, and ignition is performed.

At this time, the gas nozzle 300 burns the gas in the body 100 and the preheating socket 400. In this case, the gas nozzle 300 is inserted into the body 100 and the preheating socket 400 The ignition is smoothly performed without being affected by the wind.

However, since sufficient air required for combustion is supplied to the gas nozzle 300 through the outer hole 110 formed in the body 100 and the inner hole 420 formed in the preheating socket 400, The burning can be done without being influenced by wind even after ignition.

In addition, since the preheating pipe 600 is connected to the body 100 and the preheating socket 400 through a certain interval, the gas supplied to the gas nozzle 300 through the preheating pipe 600 Since it is stably preheated for a sufficient time, it is possible to achieve a smooth combustion even at a high altitude or a low temperature.

In addition, a step 410 is formed in the preheating socket 400 and a flame radiation plate 500 is provided at the entrance thereof, thereby obtaining the maximum thermal power with minimum gas consumption.
