Description

Gas burner head and portable gas burner using the same {BURNER-HEAD AND PORTABLE GAS COMBUSTION APPARATUS USING THE SAME}

The present invention relates to a portable gas combustor for cooking and cooking, and more specifically, to ensure that the mixture of liquefied butane gas and air is evenly dispersed and spread and the pressure is applied evenly to produce a stable flame. This relates to a double burner gas burner head that significantly improves combustion efficiency and heat generation performance and a portable gas burner using the same.

Today, as the number of people enjoying outdoor activities such as hiking, camping, and fishing increases, the demand for portable gas burners used for outdoor cooking or cooking is increasing.

These portable gas burners mainly use liquefied butane gas filled in a disposable bomb in the form of a metal can as fuel and can be ignited without preheating.

For example, in Patent Document 1, as shown in FIG. 1, the gas supplied through the fuel supply unit 40 is blown out from the nozzle, mixed with air, and blown out to the burner head part 50, and the ignition switch 70 and plug unit. (60) A burner is disclosed that ignites and heats with a flame ejected during combustion.

However, this is a simple structure in which heat is generated by a flame emitted when a mixture of gas and air combusts in the burner head unit 50, that is, a mixture of the gas injected from the nozzle and the air around the nozzle is supplied and burned, thereby creating a flame ball. Since the structure ejects the flame to the outside through the flame, the flame does not bloom evenly, which has limitations in combustion efficiency and heat generation performance.

On the other hand, portable gas burners have a disadvantage in that they are difficult to vaporize sufficiently when the temperature is low, such as in winter, or when the amount of liquefied butane gas remaining in the gas cylinder (bomb) is small, resulting in lower heating power.

In addition, in the case of a method in which combustion occurs on the surface of the crater, a regulator is essential to control and maintain the supply pressure of the gas at a constant pressure. If the gas cylinder is carelessly shaken or turned over to increase the flame during use, the liquefied gas regulator must be used. As it flows directly into the firebox that emits flames, the flame suddenly grows as if exploding, and severe soot is generated due to incomplete combustion, which increases the risk of fire.

Meanwhile, Patent Document 2 discloses a portable burner in which two burners of different sizes are arranged concentrically to enable efficient use of the flame and to variably use it to suit various cooking vessels.

However, in the case of the outer fire pit, the pressure and speed of the mixer are relatively high, so there is a problem in that the flame does not bloom stably in the flame ball near the inlet and extinguishes or flickers.

In other words, there is a problem in that the mixture does not disperse and flow uniformly in the crater, but instead flows unevenly through a portion of the firebox, resulting in a drift phenomenon that causes the flame to not normally maintain a certain shape at a certain position, resulting in problems and defects.

The background or prior art described above herein is information possessed by the present inventor or acquired in the process of deriving and completing the present invention, and is helpful in understanding the technical significance of the present invention and useful for prior art search and examination. It is to be noted that this does not mean a technology generally known and widely used in the technical field to which the invention pertains before the application of the present invention, and in addition, the reference numerals in the prior art are unrelated to the reference numerals in the present invention. .

An outer venturi tube that mixes the gas blowing out from the nozzle and the air flowing in through the air inlet to disperse and diffuse through pressure changes, and a mixer that is mounted on the outer circumference of the inner head and blows out through the outer venturi tube. A ring-shaped tubular outer head that disperses discharge through a plurality of flame balls is mounted on the upper side of the outer venturi tube inside the outer head to change the flow direction of the mixture ejected upward through the inner venturi tube to buffer and vortex. A shade that helps smooth the mixing action by generating a shade, a plurality of agents that are mounted on the shade in the outer head to increase the moving speed of the mixer due to the pressure difference, and to uniformize the mixing state by changing the circumferential flow in the up and down directions.

Here, the base 10 may be formed of an insulator (poor conductor) that has very high heat resistance and does not transmit heat well, that is, has low thermal conductivity.

In addition, a handle 13 may be attached to the upper part of the base 10 to enable it to be conveniently held by hand, and support legs may be attached to all sides of the lower part to support and adjust the height so that the base 10 is positioned at a certain height from the floor.

The adapter 20 is provided to connect to the nozzle of the gas cylinder C and connect to the branch 30.

The branch 30 is installed on the bracket 11 in the base 10 to evenly distribute the gas supplied through the adapter 20 to the first and second gas supply pipes 31 and 32.

Here, one end of the first gas supply pipe 31 in the longitudinal direction is connected to the branch 30, the other end is connected to the valve casing 41 of the first governor 40, and a part in the middle They are arranged at regular intervals around the inner head 70.

That is, as the liquefied butane gas in the gas cylinder (C) passes through the first gas supply pipe (31), it is naturally preheated and vaporized to an appropriate temperature by the radiant heat of the inner head (70) and supplied to the first governor (40), so the temperature increases. Even if it is low, complete and stable combustion can be achieved for a long time.

And the second gas supply pipe (32) has one end in the longitudinal direction connected to the branch (30), the other end connected to the valve casing (81) of the second governor (80), and a part in the middle. They are arranged at regular intervals around the outer head 110.

That is, as the liquefied butane gas in the gas cylinder (C) passes through the second gas supply pipe (32), it is naturally preheated and vaporized to an appropriate temperature by the radiant heat of the outer head (110) and is supplied to the second governor (80), thereby increasing the temperature. Even if it is low, complete and stable combustion can be achieved for a long time.

The first governor 40 adjusts the gas supply pressure and controls the flow amount of gas supplied from the gas cylinder C through the first gas supply pipe 31 to the first nozzle 50 within a certain range (base ( It is installed on the bracket 11 in 10).

That is, as shown in FIG. 9, the first governor 40 performs an opening and closing operation in which the spindle 42 moves in the horizontal direction as it rotates within the gas passage 43 of the valve casing 41 to open or close the passage by widening it. Thus, the amount of gas ejected from the gas cylinder (C) supplied to the first nozzle (50) can be adjusted to a certain range.

In addition, a valve head 45 is formed at one end in the longitudinal direction of the spindle 42, which is in close contact with the valve seat 44 in the gas passage 43, and at the other (opposite) end to facilitate rotation. There is a knob (46) that does this.

That is, a part of the spindle 42 is screwed while being inserted into the gas passage 43 of the valve casing 41, and the gap between the valve head 45 and the valve seat 44 is adjusted by rotating the gas passage. The amount of gas ejected from (C) supplied to the first nozzle 50 can be adjusted within a certain range.

The first nozzle 50 is installed at the lower part of the inner venturi pipe 60 to blow out the gas supplied through the first governor 40.

And the first nozzle 50 is connected to the first governor 40 through a separate gas supply pipe.

The inner venturi pipe 60 mixes the gas emitted from the first nozzle 50 with the air flowing in through the first air inlet 61 and mixes it with the bracket 11 in the base 10 to disperse and diffuse it through pressure changes. ) It is installed in the center.

That is, the inner venturi pipe 60 is made of a hollow tube shape with a certain length in order to mix the gas ejected from the first nozzle 50 and external air, and around the middle part there is a hole where external air flows into the inside. A plurality of first air inlets 61, which are passages, are formed.

Here, it is desirable to form a plurality of heat dissipation fins to protrude on the outer peripheral surface of the inner venturi tube 60 so as to draw heat from the inside and dissipate and dissipate it quickly into the air.

The inner head (70) disperses and discharges the mixture ejected through the inner venturi pipe (60) through a plurality of inner flame holes (71) drilled around the inner head (70) to produce an even flame in the upper center of the base (10). It is mounted on.

That is, the central part of the inner head 70 is connected to the upper end of the inner venturi pipe 60.

The second governor 80 adjusts the gas supply pressure and controls the flow amount of gas supplied from the gas cylinder C through the second gas supply pipe 32 to the second nozzle 90 within a certain range. It is installed on the bracket 11 in 10).

In other words, as shown in FIG. 10, the second governor 80 operates in an opening/closing operation in which the spindle 82 moves in the horizontal direction as it rotates within the gas passage 83 of the valve casing 81 to open or close the passage by widening it. Thus, the amount of gas ejected from the gas cylinder (C) supplied to the second nozzle (90) can be adjusted to a certain range.

In addition, a valve head 85 is formed at one end in the longitudinal direction of the spindle 82, which is in close contact with the valve seat 84 in the gas passage 83, and at the other (opposite) end to facilitate rotation. There is a knob (86) that does this.

That is, a part of the spindle 82 is screwed while being inserted into the gas passage 83 of the valve casing 81, and the gap between the valve head 85 and the valve seat 84 is adjusted by rotating the gas passage 83. The amount of gas ejected from (C) supplied to the second nozzle 90 can be adjusted within a certain range.

The second nozzle 90 is installed at the lower part of the outer venturi pipe 100 to blow out the gas supplied through the second governor 80.

And the second nozzle 90 is connected to the second governor 80 through a separate gas supply pipe.

The outer venturi pipe 100 mixes the gas emitted from the second nozzle 90 with the air flowing in through the second air inlet 101 and mixes it with the bracket 11 in the base 10 to disperse and diffuse it through pressure changes. ) It is installed on one side.

That is, the outer venturi pipe 100 is made up of a hollow tube shape with a certain length in order to mix the gas emitted from the second nozzle 90 and external air, and around the middle part there is a hole where external air flows into the inside. A plurality of second air inlets 101, which are passages, are formed.

The outer head 110 uniformly distributes and discharges the mixture of gas and air blowing out through the outer venturi pipe 100 through a plurality of outer flame holes 111 drilled around it, creating a ring-shaped shape when ignited. It is made up of a round ring-shaped tube to make a flame bloom.

And the outer head 110 is placed around the outer circumference of the inner head 70 and supported by a separate bracket.

That is, the outer head 110 is formed through a round ring-shaped tube and has several open outer flame holes 111 around it as fire holes to heat a large area with a small flame, and its round edge On one side, a connection hole 118 is formed to connect and couple to the upper end of the outer venturi pipe 100.

In order for the outer head 110 to apply the pressure and speed of the mixer evenly so that the thermal power is spread evenly without deviation, the cross-sectional area in contact with the mixer becomes smaller and deeper as it moves away from the connection part with the outer venturi pipe 100. It is shaped like a ring burner that gradually gets lower.

In other words, due to the morphological characteristics of the outer head 110 in the shape of a ring burner with a gradually smaller cross-sectional area and a lower depth, the pressure and speed can be applied uniformly as the flow of the mixer moves from a wide space to a narrow space according to Bernoulli's theorem. there is.

The shade 112 changes the flow direction of gas and air to cushion it and creates a vortex to help smooth the mixing process.

And the shade 112 is mounted on the upper side of the outer venturi pipe 100 inside the outer head 110.

That is, the shade 112 is fixed to the lower surface of the baffle 114 so as to be located above the connection hole 118 of the outer head 110.

In addition, on both left and right sides centered on the outer venturi pipe 100 of the shade 112, outward flanges 113 that facilitate vortex generation are formed to protrude horizontally.

The baffle 114 increases the moving speed of the mixer due to the pressure difference, changes the circumferential flow up and down to make the mixing state uniform, and also serves to prevent backfire.

That is, the baffle 114 narrows the cross-sectional area of the mixer passage to increase the moving speed of the mixer due to the pressure difference, and a plurality of baffles are formed around the shade 112 to induce the mixer to be concentrated on the upper side of the outer venturi pipe 100. One port (115) is arranged at regular intervals, and on the other side of the outer venturi pipe (100), it is formed as a ring-shaped plate having a plurality of second ports (119) with a smaller diameter than the first port (115). .

And the baffle 114 is mounted on the shade 112 in the outer head 110.

The baffle cover 116 allows the pressure of the mixer passing through the first and second ports 115 and 119 to uniformly act on the inner surface of the cover 110a of the outer head 110 and the upper part of the outer head 110. It plays a role in circulating space.

That is, the baffle cover 116 has a plurality of distribution holes 117 radially opened at regular intervals to evenly distribute the flow of the mixture and discharge it to the outer flame hole 111.

And the baffle cover 116 is mounted on the baffle 114 in the outer head 110.

Here, the outer head 110 is composed of a main body 110a and a cover 110b and is formed by dividing them into upper and lower parts, and a shade 112, a baffle 114, and a baffle cover 116 are installed inside it by bolting or welding, etc. Of course, it can be fixed and integrated using the joining method.

Meanwhile, as shown in FIGS. 2 and 4, the portable gas burner according to an embodiment of the present invention further includes a grate 120, a first ignition 130, and a second ignition 140.

The grate 120 is mounted in at least three directions among the edges of the upper surface of the base 10 to stably support heating objects such as cooking utensils such as pots and pots.

Here, the grate (120) can stably support various cooking utensils depending on their size, and may be formed in a foldable form where parts of the grate are folded to increase convenience and space efficiency when carrying and storing by minimizing the volume according to the user's needs and choices. there is.

The first ignition 130 is mounted on one side of the base 10 to ignite the mixture of gas and air discharged through the inner flame hole 71 of the inner head 70.

The second ignition 140 is mounted on the other side of the base 10 to ignite the mixture of gas and air discharged through the outer flame hole 111 of the outer head 110.

Here, the first and second ignitions 130 and 140 may adopt a piezo structure that generates voltage and electric sparks by applying pressure.

The main operation and operating principles of the gas burner head according to the embodiment of the present invention configured as described above and the portable gas burner using the same are described as follows.

First, the gas supplied from the gas cylinder (C) is distributed from the branch 30 and then flows into the first governor 40 through the first gas supply pipe 31 and flows through the first nozzle 50 into the inner venturi pipe ( 60) It is sprayed inside.

At this time, due to a pressure change in which the surrounding air pressure drops, external air is naturally sucked into the inner venturi pipe 60 through the first air inlet 61, forms a mixture with gas, and is supplied to the inner head 70.

Subsequently, the mixture of gas and air in the inner head 70 is uniformly dispersed and diffused and discharged through a plurality of inner flame holes 71.

In this state, when the mixture of gas and air discharged through the inner flame hole 71 is ignited with an ignition device such as an electric spark of the first ignition 130 or a lighter, flames appear along the edge of the inner head 70. It blooms evenly and stably and can heat objects such as pots.

In other words, gas and air are mixed within the inner head 70 and are evenly dispersed and spread to create an even flame, thereby greatly improving combustion efficiency and heat generation performance.

At this time, the spindle 42 of the first governor 40 can be rotated to change its position to adjust the gas ejection amount and pressure of the gas cylinder C within a certain range, thereby freely adjusting the thermal power and flame intensity.

Meanwhile, the gas supplied from the gas cylinder (C) is distributed from the branch 30 and then flows into the second governor 80 through the second gas supply pipe 32 and flows through the second nozzle 90 into the outer venturi pipe ( 100) It is sprayed inside.

At this time, due to the pressure change, the surrounding air pressure drops, and external air is naturally sucked into the outer venturi pipe 100 through the second air inlet 101, forming a mixture with the gas, and is supplied to the outer head 110.

In this process, the second ventry pipe 100 supplies the mixture at a high pressure to produce a strong flame during combustion, so the pressure of the mixture must be lowered and stabilized before being uniformly distributed and supplied to the outer head 110. ) can form a flame evenly throughout the outer flame hole (111).

That is, as shown in FIG. 11, the shade 112 located inside one side of the outer head 110 connected to the outer venturi pipe 100 is ejected upward through the outer venturi pipe 100. By changing the flow direction of the mixer to cushion it and creating a vortex to help smooth the mixing action, it prevents the flame rising through the outer flame hole (111) around the connection part from the outer venturi pipe (100) from going out or flickering. can do.

To elaborate, the mixer supplied through the outer venturi pipe 100 first strikes the inside of the shade 112 to form a vortex, and the vortex thus formed changes the direction of the flow by colliding with and guiding the outward flange 113. By changing the circumferential direction, a vortex can be created, allowing for smooth mixing.

In addition, the mixer in the outer head 110 that has passed through the shade 112 flows in the circumferential direction in a uniformly mixed state by the baffle 114 mounted on the shade 112, and then flows into the outer venturi pipe 100. A plurality of first ports 115 formed intensively on the upper side and a plurality of second ports 119 opened on the upper side opposite to the outer venturi pipe 100 with a relatively smaller diameter than the first ports 115. As it passes through, the flow changes in the up and down direction, and the moving speed increases due to the pressure difference that occurs at this time.

In other words, the mixer with relatively low pressure and speed rises through the first port 115, and the mixer with relatively high pressure and speed rises through the second port 000, so that the mixer with uniform pressure and speed is created in the baffle. It may be supplied to the cover 116.

Afterwards, the flow of the mixture passing through the first port 115 and the second port 119 changes in the circumferential direction as it hits the baffle cover 116, and is stabilized and distributed at even pressure and speed, forming the outer flame hole 111. is discharged evenly.

That is, the mixture of gas and air supplied into the outer head 110 is uniformly dispersed and diffused by the shade 112, the baffle 114, and the baffle cover 116, and thus flows through a plurality of outer flame holes 111. The flame can rise steadily without drift.

In this state, when the mixture of gas and air discharged through the outer flame hole 111 is ignited with an ignition device such as an electric spark of the second ignition 140 or a lighter, a ring is formed along the circumference of the outer head 110. The shaped flame blooms evenly and stably and can heat objects such as cooking containers.

That is, gas and air are mixed within the outer head 110 and are evenly dispersed and spread to create an even flame, thereby significantly improving combustion efficiency and heat generation performance.

At this time, the spindle 82 of the second governor 80 can be rotated to change its position to adjust the gas ejection amount and pressure of the gas cylinder C to a certain range, thereby freely adjusting the thermal power and flame intensity.

Moreover, as the outer head 110 moves away from the connection portion with the outer venturi pipe 100, the cross-sectional area in contact with the mixer becomes smaller and the depth becomes lower, so the location of the outer venturi pipe 100 and Regardless, the pressure and speed of the mixer in the outer head 110 work uniformly to increase heating efficiency due to complete combustion, and can also reduce the emission of environmental pollutants such as carbon monoxide and nitrogen oxides due to incomplete combustion.

Meanwhile, the outer head 110, which constitutes the gas burner head according to an embodiment of the present invention, has a shade between the main body 110a to which the outer venturi pipe 100 is connected and the cover 110b in which the outer flame hole 111 is formed. (112), the outward flange 113, the baffle 114, and the baffle cover 116 have a structure in which they overlap at small intervals, so if the overall spacing is unevenly combined during the assembly process, the mixer will ultimately be blown into the outer flame hole ( 111), it may not be discharged evenly.

To solve this problem, as shown in FIG. 12, the baffle cover 116 has a number of distribution holes 117 at regular intervals to evenly distribute the flow of the mixer.

That is, even if uneven spacing between parts occurs in the process of assembling the outer head 110, the flow of the mixer passing through the first port 115 and the second port 119 hits the baffle cover 116 and moves in the circumferential direction. As it changes to , it stabilizes at even pressure and speed, and in this state, it is naturally distributed while passing through the distribution holes 117 opened at regular intervals in the baffle cover 116, so it can be evenly discharged through the outer flame hole 111.
