In the embodiment of the present invention, a double burner in which two burners are used in one burner body 31 will be described as an example, and a burner having a circular appearance will be described.

A first burner 50 is formed on the upper side of the burner main body 31 and is formed in a circular ring shape in which a central portion is cut out to a predetermined area, And a second burner 60 positioned at a cut-off central portion of the first burner 50 and having a relatively small inner space and relatively narrower space for heating a relatively narrow area.

The first burner 50 is supported on the upper surface of the burner main body 31 and has a first air hole 52 for providing a passage through which a flame is emitted along a side surface, A head 51 and a first mixing pipe 53 for guiding gas and air into the internal space of the first burner head 51.

The second burner head 61 has a first burner head 61 and a second burner head 61, .

In order to prevent the first burner head 51 from being affected by the flame emitted from the second bleed hole 62 formed along the side surface of the second burner head 61, Is positioned so as to be spaced apart from the central portion of the first burner head 51 by a predetermined distance so that the second air hole 62 is formed above the upper surface of the first burner head 51.

As described above, the first burner head 51, in which the flame is formed in a relatively large area, is heated by the first burner head 51 having a relatively large lower surface and containing a food or food, The second burner head 61 heats the food container having the narrow bottom surface or the food container containing the food.

Of course, it is also possible to use the flame emitted from the first burner head 51 and the second burner head 61 to heat the food container containing the food or the food, 2 flames emitted from the burner heads 51 and 61 may be adjusted to different intensities so as to heat the lower surface of the food or food container to flames of different intensities.

In this way, the first burner head 51 and the second burner head 61 can be controlled, respectively, so that the user can use the gas burner 30 to cook food having various forms, It has the advantage of cooking food.

Hereinafter, the gas burner 30 will be described in detail with reference to the accompanying drawings. FIG. 3 is an exploded perspective view showing a configuration of a gas burner of a cooking device according to an embodiment of the present invention, and FIG. 4 is a bottom perspective view showing a first burner bottom of the gas cooking appliance according to an embodiment of the present invention have.

Referring to FIG. 1, a central hole 34 is formed in the central portion of the upper surface of the burner main body 31 to have a predetermined diameter and cut out into a circular shape. On the both sides of the central hole 34, An inlet 33 is formed which provides a passage for flowing into the inner space of the valve body 31.

The inlet 33 is formed to have a predetermined area and is formed to have a substantially fan shape in such a manner that the cross-sectional area of the burner body 31 becomes narrower toward the center hole 34 from the upper edge of the burner body 31.

The inlet port 33 is formed to have a length longer than a rim portion farther from the center hole 34 and closer to the center hole 34 than the center hole 34, 11 so as to allow more air to flow so that air in the outer space passes through the inlet 33.

The more air flows into the inlet 33, so that the amount of air flowing into the internal space of the burner main body 31 through the inlet 33 becomes greater. The air to be mixed with the gas supplied to the inner space of the burner main body 31 due to the larger amount of air can be sufficiently supplied to prevent the combustion of the gas due to the lack of air.

The inlet port 33 is formed by cutting off a part of the upper surface of the burner main body 31. When the top surface of the burner main body 31 is viewed from above, the rim has a longer fan shape, So that more air passes through the inlet 33 and moves to the inner space of the burner main body 31. [

The outer edge of the inlet 33, that is, the portion closest to the edge of the upper surface of the burner main body 31 is formed at a position spaced inward from the upper edge of the burner body 31 by a predetermined distance, So as to protrude upward.

In this way, the outer edge of the inlet 33 is formed at a position spaced away from the center hole 34 by a predetermined distance from the upper edge of the burner body 31, so that the upper plate 11 The upper plate 11 is supported by the upper surface of the burner main body 31 while being positioned.

That is, a portion of the gas burner 30 is cut so as to have a certain area in order to allow the gas burner 30 to pass through the upper plate 11, and a rim portion of the cut- As shown in Fig.

At this time, the outer edge portion of the inlet port 33 closest to the upper edge of the burner main body 31 is formed to protrude upward with a predetermined height, so that the upper plate 11 is connected to the gas burner 30 can pass through in the vertical direction, the position of the burner main body 31 can be guided.

The lower edge of the first burner head 51 is spaced apart from the upper edge of the burner main body 31 by a predetermined distance and is supported by the upper edge of the burner main body 31, External air located on the upper surface of the upper plate 11 flows into the inner space of the burner main body 31 through the inlet 33 while moving to the upper edge of the burner main body 31. [

It is preferable that the outer edge portion of the inlet port 33 is formed to protrude further downward than the upper surface of the upper plate 11. This is to facilitate the flow of air toward the inlet port 33 along the upper surface of the upper plate 11.

That is, if the outer edge portion of the inlet port 33 is protruded upward from the upper surface of the upper plate 11, the flow of air toward the inlet port 33 along the upper surface of the upper plate 11 is prevented So that the air directed to the inlet port 33 can not flow smoothly and sufficient air can not pass through the inlet port 33.

The other edge portion of the inlet 33 protrudes further than the outer edge portion and the separating member 40 is positioned to contact the lower surface of the first burner head 51. The separating member 40 includes a first member 41 forming a space through which the secondary air of the second burner head 61 flows and forming an upper surface of the burner main body 31, And a second member (42) located at the rim portion and restricting air movement to the space excluding the upper surface of the inlet (33).

The first member 41 forms an upper surface of the burner main body 31 while forming a certain thickness. At this time, the first member 41 may be integrally formed with the burner main body 31, or may be coupled to the burner main body 31 with different parts.

That is, the upper surface of the separating member 40 is formed by the first member 41 and protruded upward along the rim of the inlet port 33, And a second member 42 which restricts the flowing air from flowing into the other space except the upper side of the inlet 33.

The separating member 40 flows into the inner space of the burner main body 31 by the constitution of the first member 41 and the second member 42 so that the first burner head 51, The second burner head 61 moves to the inner space of the second burner head 61 and flows into the space for the air for primary combustion of the mixed gas mixed with the air and the space for the secondary air for the secondary combustion of the second burner head 61 As shown in FIG.

The first member 41 which forms the upper surface of the burner main body 31 on the upper side of the burner main body 31 and the second member 41 which has a length upwards along the rim portion of the inlet port 33 The upper surface of the second member 42 is formed to be in contact with the lower surface of the first burner head 51 while being moved along the upper surface of the upper plate 11 So that the air to be moved to the outer edge of the inlet port 33 is spatially divided so as not to move to the portion except the upper surface of the inlet port 33. [

The second member 42 may be formed integrally with or separate from the first member 41 while being protruded upward along the rim of the inlet 33, It is also possible that a portion covering the upper side of the inlet port 33 is further formed so as to restrict upward movement of the air in the internal space of the burner main body 31 through the inlet port 33. [

That is, the gas flows into the inner space of the burner main body 31 while flowing into the inlet port 33 by the separating member 40, flows into the inner space of the first and second burner heads 51 and 61, (61) of the second burner head (61) while flowing from the upper surface of the burner main body (31) to the second burner head (61), a primary air supply space for supplying primary air for primary combustion of the first burner head The secondary air supply space for the secondary combustion of the mixed gas burned in the combustion chamber 62 is spatially separated.

The upper surface of the burner main body 31 is divided by the separating member 40 into a space in which the inlet port 33 is formed and a space in which the inlet port 33 is formed, The flow path of the moving air and the flow path of the air moving toward the center hole 34 are formed by different spaces.

Therefore, the air flowing toward the inlet port 33 and the air flowing toward the center hole 34 are formed in different spaces, thereby forming independent flow paths.

The air moving to the inlet 33 moves to the inner space of the burner main body 31 and moves to the first and second burner heads 51 and 61 in the inner space of the burner main body 31, So that the influence generated in the outer space of the main body 31 is minimized. That is, due to the influences of the air flow generated when the user uses the kitchen furniture, the first and second burner heads 51 and 61 are not affected by the flow of air moving to the first and second burner heads 51 and 61, It does not affect the flames generated in the heat exchangers 51 and 61, so that the container containing the food or food can be uniformly heated.

Since the flame emitted from the first and second burner heads 51 and 61 is prevented from being extinguished by the flow of air generated in the outer space of the burner main body 31, The leakage of the gas does not occur and the safety of use of the gas burner 30 is improved.

On the other hand, a first mixing pipe (not shown) which is integrally formed on the lower surface of the first burner head 51 and guides the flow of gas injected at a high pressure in the inner space of the burner main body 31, 53). The first mixing pipe 53 has an inner space of a certain degree and an upper end thereof is opened so that the inner space of the first mixing pipe 53 is connected to the inner space of the first burner head 51.

When the gas is injected into the inner space of the first mixing pipe 53 by the high pressure in the inner space of the burner main body 31, the gas flows into the inner space of the first mixing pipe 53, The air in the outer space flowing into the inner space of the burner main body 31 through the inlet 33 flows into the inner space of the first mixing pipe 53. [

The air and the gas simultaneously flowing into the inner space of the first mixing pipe 53 are mixed with each other while moving upward in the inner space of the first mixing pipe 53. The gas mixed with the air, 1 to the inner space of the burner head 51 and flows into the outer space through the first air hole 52 formed along the side surface of the first burner head 51.

The mixed gas is burnt by igniting the mixed gas flowing into the outer space of the first through-hole 52. In this way, the flame generated by the combustion of the mixed gas is generated along the side surface of the first burner head 51, while the food or food containing the food placed on the grate 13 located above the gas burner 30 The food is cooked by heating the container.

The first burner head 51 may be integrally formed with the first burner head 51 having an inner space so as to open the upper surface of the first burner head 51. The first burner head 51, It is also possible to form it.

A second mixing pipe 63 extending downward from the lower surface of the second burner head 61 is provided in the center hole 34 formed at the center of the upper surface of the burner main body 31. The second mixing pipe (63) has a cylindrical shape with a predetermined diameter and an open top and a bottom.

That is, the inner space of the second mixing tube 63 supported on the lower surface of the second burner head 61 is formed to communicate with the inner space of the second burner head 61, and the second mixing tube 63, The lower surface of the burner main body 31 is formed to pass through the center hole 34 formed in the upper surface of the burner main body 31 in the vertical direction and to be positioned below the center hole 34 to communicate with the inner space of the burner main body 31 do.

The second mixing tube 63 supported on the lower surface of the second burner head 61 performs the same function as the first mixing tube 53 supported on the lower surface of the first burner head 51 . In other words, the gas supplied from the inner space of the burner main body 31 and the air flowing into the inner space of the second mixing tube 63 are mixed together, 2 to the inner space of the burner head 61 and flows into the outer space through the second air hole 62 formed along the side surface of the second burner head 61. This mixed gas is ignited to generate a flame .

The flame generated through the second bleed hole 62 cooks the food while heating the food container containing the food or the food placed on the upper side of the grate 13 located on the upper side of the upper plate 11 . Of course, since the cross-sectional area of the second burner head 61 is relatively narrower than the cross-sectional area of the first burner head 51, the relatively small area is heated compared with the flame emitted from the first burner head 51 .

The second burner head 61 is formed in a disc shape having an open top surface while forming a certain degree of internal space, and a second burner cap is provided on the opened top surface to shield the top surface of the second burner head 61 It is also possible that the mixed gas mixed with the air is not leaked to other portions except for the second bleed hole 62 formed along the side surface of the first through-holes 61.

Referring to FIG. 4, the lower surface of the first burner head 51 includes a lower surface of the separating member 40 protruding upward from the upper surface of the burner main body 31, A guide member 54 guiding the position of the first burner head 51 is protruded downward with a certain length.

The guide member 54 is guided by the separating member 40 in a shape corresponding to the separating member 40. The guide member 54 is formed to have a greater width than the separating member 40 and a part of the guide member 54 has a thickness corresponding to the thickness of the separating member 40, The lower surface of the separating member 40 is formed to protrude downward so as to have a certain length from the lower surface and to be in contact with the upper surface of the separating member 40.

At this time, the other part of the lower surface of the guide member 54 extends downward to be in contact with the inner surface of the separating member 40 and extends to the inner space of the separating member 40, (51).

A portion of the lower surface of the guide member 54 is formed to be in contact with the upper surface of the separating member 40 while the other portion thereof is in contact with the outer surface of the separating member 40, It may be possible to extend further downward than the upper surface of the separating member 40 to an external space to guide the position of the first burner head 51. [

When the position of the first burner head 51 is guided by the guide member 54 and the guide member 54 is brought into contact with the separating member 40 as described above, 11 are spatially separated from other spaces except for a space in which the outside air formed on the upper surface of the upper surface of the burner main body 31 is inflow and are also spatially separated from other spaces on the upper surface of the burner main body 31.

Hereinafter, an internal configuration of a gas burner of a gas cooking apparatus according to an embodiment of the present invention will be described with reference to FIG. 5 is a side sectional view showing the internal configuration of the gas burner of the gas cooking apparatus according to the embodiment of the present invention.

The inner space of the burner main body 31 is provided with gas guide pipes 55 and 64 for guiding the flow of the gas supplied from the main supply pipe fastened to the outer surface. The gas guide pipes 55 and 64 are installed across the lower end of the inner space of the burner main body 31 with a certain degree of internal space and are connected to the first mixing pipe 53 and the second mixing pipe 63, (Not shown) for spraying the gas flowing into the inner space of the first and second gas guide pipes 55 and 64 by the first and second mixing pipes 53 and 63, ) Is installed.

In detail, the gas guide pipes 55 and 64 include a first gas guide pipe 55 for supplying gas supplied to the first mixing pipe 53 to the inner space of the burner main body 31, And a second gas guide pipe 64 for supplying the gas supplied to the second mixing pipe 63 are respectively installed and the nozzle is installed in each of the first and second gas guide pipes 55 and 64 The first and second mixing pipes 53 and 63 can supply the respective gases.

The nozzle has a nozzle hole for injecting gas at a high pressure, and the gas is injected into the inner space of the first mixing pipe (53) and the second mixing pipe (63) through the nozzle hole at a high pressure. At this time, the lower surfaces of the nozzles, the first mixing pipe 53 and the second mixing pipe 63 are spaced apart from each other by a predetermined distance.

When the nozzles and the first and second mixing pipes 53 and 63 are separated from each other and the gas is injected from the nozzle at a high pressure to the first and second mixing pipes 53 and 63, As the pressure of the space where the gas flows is formed at a low pressure, the surrounding air flows in the same direction as the gas flowing direction, and air is simultaneously introduced into the first and second mixing tubes 53 and 63.

Air flows into the first and second mixing pipes 53 and 63 at the same time as the gas, so that gas and air flow through the inner space of the first and second mixing pipes 53 and 63, Thereby forming a mixed gas. The mixed gas mixed with air is guided by the first and second mixing pipes 53 and 63 and flows into the inner space of the first and second burner heads 51 and 61.

That is, the mixed gas flowing into the first mixing pipe 53 flows into the first burner head 51 and the mixed gas flowing into the second mixing pipe 63 flows into the second burner head 61 So that it becomes possible to control the mixed gas flowing into each of the burner heads 51 and 61, respectively.

The mixed gas flowing into the inner space of each of the burner heads 51 and 61 is located in the inner space of each of the burner heads 51 and 61, And is ejected into the outer space through the air holes 52 and 62. The mixture gas is burned to generate a flame by igniting the flame on the mixed gas ejected to the external space, and the food or food container placed on the upper side is cooked by heating the flame.

The mixed gas mixed with the air exhausted through the air holes 52 and 62 in the inner space of the burner heads 51 and 61 is ignited while passing through the air holes 52 and 62 to generate a flame, Or if incomplete combustion occurs due to lack of air, secondary air for secondary combustion is required.

At this time, secondary air for secondary combustion of the first burner head 51 is supplied with air around the first burner head 51, and secondary combustion is generated. The secondary air for the secondary combustion flows through the space separated by the separating member 40 on the upper surface of the burner main body 31, that is, the air flowing into the space separated from the space where the inlet 33 is located, And secondary air for secondary combustion of the second burner head 61 is supplied.

As described above, the supply space for the secondary air for secondary combustion of the second burner head 61 is separated from the other space by the separating member 40, so that the influence due to the external environment can be prevented, The air can be uniformly supplied and smoothly supplied.

In other words, the air introduced into the space formed by the lower surface of the separating member 40, the second burner head 61, and the upper surface of the burner main body 31 on the upper surface of the burner main body 31 is directed upward And secondary air for secondary combustion including incomplete combustion generated in the second burner head 61.

The secondary air supplied to the second burner head 61 is supplied from the space formed by the separating member 40, thereby preventing the influence of the external space by the separated space.

The second mixing pipe 63 is installed closely to the center hole 34 formed at the central portion of the upper surface of the burner main body 31 and is connected to the outer surface of the second mixing pipe 63 and the center hole 34, It is preferable that the mixed gas, which is a gas mixed with the air, is not leaked.

A sealing member may be positioned between the second mixing pipe 63 and the center hole 34 to prevent leakage of the mixed gas and other leakage preventing members may be disposed to prevent gas leakage, The safety of use of the gas burner 30 is improved.

In the gas burner of the gas cooking apparatus according to the present invention configured as described above, the space in which the primary air flows and the space in which the secondary air flows, so that the secondary air supplied to the second burner head is not affected by the external environment And is spatially separated.

The space in which the primary air and the secondary air flow is separated spatially so that the flow of the secondary air is not affected by the external environment, so that the effect of smooth flow of the secondary air can be expected, The secondary combustion of the gas remaining in the burner head and the secondary combustion air for the complete combustion of the mixed gas that is incompletely combusted are smoothed, incomplete combustion is prevented, and smooth secondary combustion can be expected.

The second secondary burner can smoothly perform the secondary combustion so that the flame generated in the second burner head and emitted to the external space is uniformly formed so that the food container containing the upper food or the food is uniformly heated.

In addition, since the flow of the secondary air is smooth and the secondary combustion is smooth and the incomplete combustion is prevented, the efficiency of energy use can be expected to be improved, and the energy consumption can be reduced by the efficient use of such energy I have.
