technical field

The present invention relates to a gas radiant burner, and more particularly to a gas radiant burner capable of improving combustion efficiency by promoting the mixing of fuel gas and air.

Background technique

In general, a gas radiant burner is a burner in which the object to be heated is heated and cooked using radiant energy, which is generated when the radiant is heated by burning a gas mixture resulting from mixing fuel gas and air energy.

In the following, a conventional gas radiation burner is described with reference to the accompanying drawings.

FIG. 1 is a plan view schematically illustrating a conventional gas radiation burner, and FIG. 2 is a cross-sectional view along line I-I of FIG. 1 .

As shown in FIGS. 1 and 2 , a traditional gas radiation burner mainly includes a mixing pipe 1 , a burner pot 2 , a burner liner 3 , a burner cover 4 and glass 5 .

Here, the mixing duct 1 internally forms a space in which fuel gas and air are introduced and preliminarily mixed. Fuel gas is injected from the nozzle 1 a and introduced into the mixing duct 1 . Using the injection pressure of the fuel gas, air is introduced into the mixing pipe 1 and mixed with the fuel gas in the mixing pipe 1, thereby generating a mixed gas.

The burner pot 2 is connected to the mixing pipe 1, and forms a space inside, in which the mixed gas from the mixing pipe 1 is introduced and burned. The burner can 2 has a function of achieving more uniform mixing of fuel gas and air contained in a mixed gas introduced into the burner can 2 from the mixing pipe 1 .

The burner liner 3 is mounted on a base portion 2 a formed at the top of the burner pot 2 . The burner liner 3 has the function of emitting radiant energy, and when the mixed gas burns on the burner liner 3 , the radiant energy accumulates in the burner liner 3 .

The burner housing 4 serves as the body of the gas radiant burner. The burner pot 2 is coupled to a burner housing 4 .

In this case, the burner casing 4 has a circular opening 4 a for the passage of radiant energy emitted from the burner liner 3 .

A glass 5 is mounted at the top of the burner housing 4 . The object to be heated is placed on the glass 5 .

Meanwhile, the burner housing 4 has an exhaust pipe F serving as a passage to suck out exhaust gas generated when the mixed gas is burned.

The operation of the gas radiation burner having the above configuration will now be described.

First, if an object to be heated is placed on the upper surface of the glass 5 and the user operates the gas radiation burner, fuel gas and air are introduced into the mixing duct 1 and mixed therein. The resulting mixture is fed into the burner pot 2 and injected through the burner lining 3 .

Simultaneously, the mixed gas is ignited by a predetermined igniter (not shown) so that the mixed gas burns on the burner liner 3 . When the mixed gas burns, heat is accumulated in the burner liner 3, thus causing the burner liner 3 to emit radiant energy.

Thus, an object to be heated placed on the upper surface of the glass 5 can be heated and cooked by the radiant energy generated as described above.

In this case, the exhaust gas generated after the combustion of the mixed gas has a temperature of approximately 500 degrees Celsius or higher. Exhaust gas is discharged through an exhaust pipe F provided in the combustor housing 4 .

However, conventional gas radiant burners have problems as follows.

Firstly, the mixed gas flows directly upwards on the burner pot 2 and this causes the mixed gas to burn non-uniformly on the surface of the burner liner 3 .

Therefore, there is a problem that radiation efficiency decreases due to incomplete combustion of the mixed gas, and the amount of exhaust gas increases.

Second, if the mixing duct 1 has a reduced length due to its installation structural limitation, the mixing duct 1 may make the mixing of fuel gas and air in the mixing duct 1 uneven and thus the combustion of the mixed gas incomplete. This leads to a further decrease in radiation efficiency and a further increase in the amount of exhaust gas.

Third, conventional gas radiant burners are difficult to use as built-in products.

According to the trend of built-in home appliances, when the burner pot 2 has a reduced size and more specifically a reduced height, it is difficult for the burner pot 2 to ensure uniform mixing of the mixed gas introduced into the burner pot 2 and the mixed gas cannot pass through The burner liner 3 is sprayed evenly. This results in incomplete combustion of the mixture, resulting in reduced radiation efficiency and increased exhaust gas volume.

Fourth, variable control of heat is not possible because of limitations in the introduction of the mixed gas into the burner pot 2 and the combustion space.

Contents of the invention

Accordingly, the present invention is directed to a gas radiant burner that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.

The object of the present invention is to provide a gas radiant burner capable of improving the combustion efficiency of the mixed gas by promoting the mixing of fuel gas and air contained in the mixed gas, while enabling variable regulation of heat.

Detailed ways

Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

In the following, the gas radiation burner according to the present invention is described in more detail with reference to the accompanying drawings.

First, a gas range in which the gas radiation burner according to the present invention is used will be described with reference to FIG. 3 . Fig. 3 is a view illustrating an example of a built-in type gas range.

As shown, the gas range includes a body 100 , an oven unit 110 , a grill unit 112 and a top burner unit 114 having a plurality of gas radiant burners 130 .

The body 100 forms the appearance of the gas range. The oven unit 110 is located in a lower region of the body 100 and has a space in which food is cooked using convective heat from a plurality of heaters (not shown) installed in the oven unit 110 . The grill unit 112 has a space in which foods such as fish and meat are cooked mainly using radiant heat.

The gas radiation burner 130 is disposed on the top of the body 100 and serves as a means for cooking food by heating a container in which the food is accommodated. Glass (as indicated by reference numeral 137 , see FIG. 4 ) is fitted in the upper opening of each radiant burner 130 . Glass is primarily formed of ceramic materials.

FIG. 4 is a cross-sectional view illustrating a gas radiation burner according to a preferred first embodiment of the present invention, the burner being adapted to be used in the gas range of FIG. 3 . FIG. 5 is a plan view schematically showing the connection structure of the mixing pipe and the burner pot shown in FIG. 4 .

Referring to FIGS. 4 and 5 , each gas radiation burner 130 according to this embodiment includes a nozzle 131 , mixing pipes 132 and 133 , a burner pot 134 , a burner liner 135 , a burner housing 136 and a glass 137 . If the fuel gas is injected into the mixing pipes 132 and 133 through the nozzle 131 together with the air, the fuel gas and air are mixed in the mixing pipes 132 and 133 . The resulting mixed gas is supplied to the burner can 134 . When the mixed gas supplied from the burner pot 134 burns on the burner liner 135, the burner liner 135 is heated to thereby emit radiant heat. The burner housing 136 internally forms a combustion chamber and glass 137 is mounted at the top of the burner housing 136 .

In the gas radiation burner 130 according to this embodiment having the above-mentioned configuration, the burner pot 134, the burner liner 135, the burner housing 136, and the glass 137 have the same functions as those of the conventional gas radiation burner, and only The mixing ducts 132 and 133 have different characteristics than those of conventional gas radiant burners. Therefore, the mixing pipeline is mainly described below.

As shown in FIGS. 4 and 5 , the mixing pipes 132 and 133 of the gas radiation burner 130 according to this embodiment may be connected to a predetermined position on the side of the burner pot 134 . Preferably, the mixing pipes 132 and 133 are installed such that the mixed gas supplied from the mixing pipes 132 and 133 flows along the inner peripheral surface of the burner pot 134 . For this reason, preferably, the mixing pipes 132 and 133 are connected to the burner can 134 such that the mixing pipes 132 and 133 are close to the inner peripheral surface of the burner can 134 . More preferably, mixing ducts 132 and 133 are connected to burner can 134 in a tangential direction. With this configuration, as shown in FIG. 5, if the mixed gas is introduced into the burner pot 134 through the mixing pipes 132 and 133, the fuel gas and air of the introduced mixed gas can be more efficiently mixed with each other while The inner peripheral surface of the burner can 134 flows. Here, although the mixing pipes 132 and 133 may be connected to the burner can 134 after being separately prefabricated, it is preferable that the mixing pipes 132 and 133 are integrally formed with the burner can 134 .

The gas radiation burner 130 according to this embodiment has two mixing ducts, for example, a first mixing duct 132 and a second mixing duct 133, but the present invention is not limited thereto. That is, a single mixing duct may be provided, or two or more mixing ducts may be provided.

In the case where two or more mixing pipes are provided, as in this embodiment, as shown in FIG. 5 , the first and second mixing pipes 132 and 133 are preferably arranged so that the The mixed gas flows in a certain direction along the inner peripheral surface of the burner pot 134 . If the mixed gas supplied from the mixing pipe 131 has a different flow direction from the mixed gas supplied from the mixing pipe 132 , there is a problem in that the flow efficiency of the overall mixed gas supplied into the burner tank 134 decreases. More preferably, as shown in FIG. 5 , the first and second mixing pipes 132 and 133 may be connected to the burner pot 134 such that the first and second mixing pipes 132 and 133 are symmetrical to each other. With the symmetrically arranged mixing pipes 132 and 133 , the mixed gas supplied into the burner can 134 can flow along the inner peripheral surface of the burner can 134 more efficiently. This has the effect of promoting mixing of fuel gas and air.

In conclusion, the gas radiation burner 130 according to this embodiment has an effect of promoting more uniform mixing of the fuel gas and air contained in the mixed gas by allowing the mixed gas to flow along the inner peripheral surface of the burner pot 20 . It is fed into the burner pot 134 from the first and second mixing pipes 132 and 133 . Improving the mixing uniformity of the mixed gas allows the mixed gas to burn uniformly and stably on the surface of the burner liner 135, thereby improving radiation efficiency and reducing the amount of exhaust gas.

Also, by adopting a multiple injection structure by using the first mixing pipe 132 and the second mixing pipe 133, it is possible to realize a high burner turndown ratio (Turn Down Ratio (TDR)) and realize uniform mixing of the mixed gas even when the burner can 134 has a reduced size (ie, a reduced height). Therefore, the gas radiation burner 130 according to this embodiment is suitable to be used in a built-in type product.

Now, a second embodiment of the gas radiation burner according to the present invention will be described with reference to FIG. 6 . Fig. 6 is a plan view schematically illustrating important parts of a gas radiation burner according to a second embodiment of the present invention. Compared with the previous embodiment, the gas radiation burner 130 according to this embodiment is different in that a plurality of first mixing ducts 132 and a plurality of second mixing ducts 133 are provided and a mixing promoting member 140 is also provided, but other configurations and reference numerals Reference may be made to those of the preceding embodiments.

As shown in FIG. 6, the gas radiation burner 130 according to this embodiment may also have a plurality of first mixing ducts 132 and a plurality of mixing ducts 133 connected to predetermined positions on the side of the burner tank 134, and a mixing promoting member 140, which are respectively near the outlet side of the first mixing pipe 132 and the outlet side of the second mixing pipe 133, the mixing promoting member 140 is used to promote the mixing of fuel gas and air of the mixed gas supplied to the burner tank 134. The mixing promoting member 140 may be installed to protrude upward by a predetermined length from the inner bottom surface of the burner can 134 .

Preferably, mixing promoting members 140 are arranged between the plurality of first mixing ducts 132 and between the plurality of second mixing ducts 133, respectively. With this arrangement, the mixed gas supplied from the first mixing pipe 132 and the second mixing pipe 133 can flow more efficiently through the mixing promoting member 140 and have fuel gas that promotes the mixed gas supplied into the burner tank 134 The effect of mixing with air.

More preferably, the mixing promoting member 140 has a streamline shape corresponding to the bending direction of the inner peripheral surface of the burner can 134 . With this configuration, the mixed gas supplied from the first mixing pipe 132 and the second mixing pipe 133 can flow more efficiently along the inner peripheral surface of the burner can 134 and along the mixing promoting member 140 . This has the effect of promoting more uniform mixing of fuel gas and air.

In conclusion, with the use of the mixing promoting member 140, the gas radiation burner 130 according to this embodiment can achieve a more efficient flow of the mixed gas supplied into the burner pot 134 and can promote the flow of the fuel gas as compared with the first embodiment described above. Mix more evenly with air.

Next, a third embodiment of the gas radiation burner according to the present invention will be described with reference to FIG. 7 . Fig. 7 is a plan view schematically illustrating important parts of a gas radiation burner according to a third embodiment of the present invention. Compared with those of the preceding embodiments, the difference of the gas radiation burner 130 according to this embodiment is that a plurality of mixing pipes are connected to the burner tank 134 so as to be symmetrical to each other and a flow promoting member 150 is further provided, but other configurations and reference The numbers refer to those of the preceding examples.

As shown in FIG. 7, the gas radiation burner 130 according to this embodiment may also have four mixing ducts 151, 152, 153, and 154 connected to the burner tank 134 so as to be symmetrical to each other, and to A flow promoting member 150 for the flow of the mixed gas discharged from each mixing pipe.

Preferably, the flow promoting member 150 is a fan having one side for sucking the mixed gas supplied from the four mixing ducts into the burner pot 134, and the other side for discharging the sucked gas. of mixed gas. More preferably, the fans are respectively arranged near the outlet ends of the respective mixing ducts. With this configuration, if the mixed gas is supplied from the mixing pipe into the burner pot 134, the mixed gas is forcibly moved by the flow promoting member 150, ie, the fan, thereby achieving a more efficient flow of the mixed gas. This thus promotes a more uniform mixing of the fuel gas and air of the mixed gas.

Although the gas radiation burner 130 according to this embodiment has four mixing ducts, the present invention does not limit the number of mixing ducts. Also, similarly to the foregoing first embodiment, preferably, the plurality of mixing ducts are arranged such that the mixed gas supplied from the mixing ducts flows in a direction along the inner peripheral surface of the burner can 134 .

A fourth embodiment of the gas radiation burner according to the present invention is described with reference to FIG. 8 . Fig. 8 is a sectional view schematically illustrating an important part of a gas radiation burner according to a fourth embodiment of the present invention. Compared with the previous embodiment, the gas radiation burner 130 according to this embodiment differs in the structure of the burner pot 134 and the burner liner 135, but other structures and reference numerals refer to those of the previous embodiment.

As shown in FIG. 8 , a gas radiation burner 130 according to a fourth embodiment of the present invention may have a burner liner 163 installed obliquely at the top of a burner pot 161 . Here, the combustor can 161 may be perforated to have a top opening 162 forming an inclined plane to allow a combustor liner 163 to be obliquely mounted to the combustor can 161 .

Combustor can 161 is coupled to combustor casing 164 after previously being coupled to combustor liner 163 . In this case, preferably, the coupling area of the burner can 161 adjacent to the glass 137 has a small coupling force, while the opposite coupling area of the burner can 161 (right side of FIG. 8 ) has a large coupling force. This is to substantially prevent the coupling forces of the burner can 161 from being transmitted to the glass 137 and thus prevent deformation of the glass 137 . Of course, it is understood that one side of the burner can 161 may be coupled directly to the glass 137 and the other side of the burner can 161 may be coupled to the burner housing 164 .

In summary, the gas radiation burner 130 according to this embodiment has the effect of reducing the height difference between the glass 137 and the burner pot 161 due to the oblique installation of the burner liner 130 so that one side of the burner pot 161 is close to the glass 137 .

A fifth embodiment of the gas radiation burner according to the present invention will be described with reference to FIGS. 9 and 10 . Fig. 9 schematically shows a sectional view of important parts of a gas radiation burner according to a fifth embodiment of the present invention. FIG. 10 is a plan view schematically showing the structure of the burner pot shown in FIG. 9 . Compared with the first to third embodiments described above, the gas radiation burner 130 according to this embodiment differs only in the burner pot 134, but other structures and reference numerals refer to those of the first to third embodiments.

The gas radiation burner 130 according to the fifth embodiment of the present invention employs a burner pot 170 having a plurality of individual spaces, and a plurality of mixing pipes can be respectively connected to the plurality of individual spaces to supply the mixed gas to each of the individual spaces. in space. In this case, the mixing pipes may be controlled to selectively supply the mixed gas into the respective spaces based on the desired amount of heat required by the object to be heated.

Optionally, a plurality of mixing ducts may be connected to each of the plurality of separate spaces. Preferably, the number of mixing ducts connected to the large-sized space is higher than the number of mixing ducts connected to the small-sized space. This is to supply an appropriate amount of mixed gas according to the size of each space.

Although the combustor can 170 according to this embodiment may have multiple separate spaces, for ease of explanation and illustration, the embodiment shown in FIGS. two spaces.

As shown in FIGS. 9 and 10 , the burner pot 170 according to this embodiment may include an inner burner pot 171 for forming a predetermined space in the center of the burner pot 170 , and an outer burner pot provided around the inner burner pot 171 . The tank 172 forms a space separate from the space formed by the inner burner tank 171 . The gas radiant burner 130 according to this embodiment may also have an inner mixing duct 174 for supplying the mixed gas into the inner burner pot 171, and an outer mixing duct 173 for feeding the mixed gas into the outer burner pot 172 . Of course, it will be appreciated that multiple internal mixing conduits 174 and multiple external mixing conduits 173 may be provided, respectively.

Preferably, the inner burner can 171 has a shape corresponding to the outer burner can 172 . In particular, when the outer burner can 172 has a circular shape, the inner burner can 171 may also have the same circular shape and be provided in the outer burner can 172 . In this case, it is more preferable that the edge of the inner burner can 171 is separated from the edge of the outer burner can 172 by a predetermined distance to obtain a space enough for the mixed gas to flow in the outer burner can 172 and enough for the mixed gas to flow. Space for flow in the inner burner pot 171 .

The inner and outer mixing pipes 174 and 173 may be respectively coupled to predetermined positions of sides of the inner and outer burner cans 171 and 172 so that mixed gas flows along inner peripheral surfaces of the inner and outer burner cans 171 and 172 . For this, preferably, the inner mixing pipe 174 can be connected to the inner burner pot 171 such that the inner mixing pipe 174 is close to the inner peripheral surface of the inner burner pot 171, and the outer mixing pipe 173 can be connected to the outer burner pot 172 so that the outer The mixing duct 173 is adjacent to the inner peripheral surface of the outer combustor can 172 . More preferably, inner and outer mixing ducts 174 and 173 are connected in tangential direction to inner and outer combustor cans 171 and 172, respectively. Thus, the mixed gas supplied from the inner and outer mixing pipes 174 and 173 can efficiently flow along the inner peripheral surfaces of the inner and outer burner cans 171 and 172 .

Typically, the outer combustor can 172 has a larger interior volume than the inner combustor can 171 . Therefore, it is preferable that the number of outer mixing ducts 173 connected to the outer burner can 172 is higher than the number of inner mixing ducts 174 connected to the inner burner can 171 . This is to achieve uniform combustion of the mixture on the surface of the combustor liner 135 . If a plurality of outer mixing pipes 173 are provided, as shown in FIG. 10 , the mixed gas discharged from the outer mixing pipes 173 is supplied in a direction along the inner peripheral surface of the outer burner can 172 . More preferably, the plurality of external mixing ducts 173 may be connected to the external combustor can 172 so as to be symmetrical to each other.

With this embodiment having the above configuration, the outer mixing pipe 173 and the inner mixing pipe 174 can be controlled to selectively supply the mixed gas according to the desired amount of heat required by the object to be heated. For example, if the object to be heated requires a small amount of heat, the mixed gas is only fed into the inner burner pot 171 through the inner mixing duct 174 so that the burner liner 135 has a small heating surface area. On the contrary, if the object to be heated requires a large amount of heat, the mixed gas is supplied into the inner and outer burner pots 171 and 172 through the inner and outer mixing pipes 174 and 173 so that the burner pad 135 has a large heating surface area.

In summary, the gas radiant burner 130 according to this embodiment makes it possible to adjust the heating surface area of the burner liner 3 where the mixed gas burns and accumulates the heat of combustion. This has the effect of changing the amount of heat transferred to the object to be heated.

A sixth embodiment of the gas radiation burner according to the present invention will be described with reference to FIGS. 11 and 12 . 11 is a sectional view schematically illustrating a gas radiation burner according to a sixth embodiment of the present invention, and FIG. 12 is a plan view schematically illustrating the structure of the burner pot shown in 11 . Compared with the fifth embodiment described above, the gas radiation burner according to this embodiment differs in the number of inner and outer mixing ducts, but other structures and reference numerals refer to those of the fifth embodiment described above.

As shown in FIGS. 11 and 12 , the gas radiation burner 130 according to the sixth embodiment of the present invention has a plurality of inner mixing ducts 174 and a plurality of outer mixing ducts 173 to achieve more efficient change of heat.

In summary, the gas radiant burner according to this embodiment has the effect of selectively adjusting the amount of mixed gas introduced into the outer burner pot 172 and the amount of mixed gas introduced into the inner burner pot 171 , thereby changing heat. Also, the gas radiant burner according to this embodiment has the effect of selectively adjusting the number of outer mixing ducts 173 in operation and the number of inner mixing ducts 174 in operation, thereby changing the heat. As a result, according to this embodiment, heat can be regulated with an increased number of stages, and this achieves a more efficient change of heat.

Here, in the case where a plurality of inner or outer mixing pipes 174 or 173 are connected to the inner or outer burner pot 171 or 172 so that the inner or outer mixing pipes 174 or 173 are arranged next to each other, as shown in FIG. Or the external mixing duct 174 or 173 preferably has a mutually different length. This takes into account the fact that the inner and outer burner cans 171 and 172 have smaller dimensions than the overall spatial dimensions of the burner can 170 . That is, the plurality of inner and outer mixing pipes 174 and 173 having different lengths from each other allows the mixed gas to be supplied into the inner and outer burner pots 171 and 172 at different positions, thereby realizing the mixing gas inside and outside. Efficient flow in burner cans 171 and 172.

As is clear from the above description, the gas radiation burner according to the present invention has the following effects.

First, the gas radiation burner enables uniform and stable combustion of the mixed gas on the burner liner surface by promoting combustion of the mixed gas, thereby improving radiation efficiency and reducing the amount of exhaust gas.

Second, promoting the combustion of the mixed gas has the effect of reducing the amount of carbon monoxide generated during the combustion of the mixed gas, improving the characteristics of the exhaust gas generated during the combustion of the mixed gas. Therefore, the present invention can significantly reduce environmental pollution.

Third, the multi-injection structure using a plurality of mixing ducts can achieve a high Turn Down Ratio (TDR), and achieve uniform mixing of the mixed gas even when the burner pot has a small size (ie, a small height). As a result, the gas radiant burner is suitable for use in built-in type products.

Fourth, it is possible to adjust the heating surface area of the burner liner where the mixed gas burns and accumulates the heat generated due to the burning of the mixed gas. This thus makes it possible to vary the amount of heat to be transferred to the object to be heated and to vary the cooking area of the gas radiant burner.
