Hereinafter, a burner for a gas cooker according to the present invention (hereinafter, simply referred to as a 'burner') will be described in detail with reference to the accompanying drawings.

Prior to the description, the gas supply unit described below is LNG (Liquefied Natural Gas) gas, commonly referred to as city gas, which is liquefied natural gas generated in the process of cooling and liquefying methane obtained by purifying natural gas collected from the gas corporation. The supply unit refers to a supply pipe for supplying LNG gas to each building (a home or a restaurant), and a detailed description thereof will be omitted so as not to obscure the gist of the present invention.

First, the burner 1 according to the present invention largely includes a gas supply member 100 and a combustion member 200, as shown in FIGS. 1 to 3 .

In more detail, the gas supply member 100 is connected to a gas supply unit (not shown), which is not shown, to supply gas (LNG) required for combustion to the combustion member 200 to be described later. It includes a housing 110 and a main nozzle 120.

For example, as shown in the drawing, the supply box 110 is molded in a donut shape as a whole to have a hollow box shape using a steel material having durability against heat, and the combustion gas supplied through the main nozzle 120 It satisfies the structure filled inside.

A plurality of first through-holes 130 are formed on the upper surface of the supply box 110 so that a plurality of sub-nozzles 210 can be radially installed therethrough, so that the combustion gas filled in the supply box 110 is passed through the supply box 110. To be uniformly supplied to the sub-nozzle 210.

At this time, at least one flange may protrude from the outer surface of the supply box 110, and it is preferable to detachably mount the cookware of the cookware 300 using a fastening means such as a bolt through the flange. do (see FIGS. 4 and 5).

On the other hand, due to the combustion gas filled in the supply box 110, the supply of combustion gas can be made smoothly even in a state where the LNG discharge pressure is low compared to the discharge pressure of liquefied petroleum gas (LPG). [The supply box 110 serves as an LPG gas storage tank.]

In addition, as shown, one side of the main nozzle 120 is installed to communicate with the inside through the lower surface of the supply box 110, and the other side is pipe-connected to the gas supply unit to provide combustion gas required for combustion in the supply box 110. so that it can be supplied refillably.

And, the combustion member 200 is mounted to communicate with the inside of the supply box 110 through the above-described first through hole 130 to receive and discharge the combustion gas filled in the supply box 110. It is a configuration for enabling the flame, which is a heat source for cooking, to be collected and ignited by implementing step-by-step mixing with external air, and includes a sub-nozzle 210, a nozzle fixture 220, and a guide body 230.

For example, as shown in the figure, a plurality of sub-nozzles 210 are installed so that the lower part of the supply box 110 can be inserted through the supply box 110 so that the combustion gas filled in the supply box 110 can be supplied. The nozzle 210 includes a column tube body 211 and a protruding body 215.

Each column tube body 211 is formed of a steel material having a column shape as a whole, but a gas movement path 213 is formed in the longitudinal direction therein, so that the combustion gas filled in the supply box 110 passes through the gas movement path ( 213) has a structure capable of moving in the upper side direction through the lower portion.

As shown, the protruding body 215 has a shape protruding in all directions to be connected to the outer surface of the columnar tube body 211, and first air inlets 217 are formed on the outer surface, respectively.

At this time, each of the first air inlets 217 is formed to have a structure in communication with the gas flow path 213 formed inside the column tube body 211, and a gap between the outside air and the combustion gas moving through the column tube body 211 is formed. It is preferable to make primary mixing so that it can be supplied in the direction of the nozzle fixture 220 (see FIG. 6).

[The velocity of the combustion gas flowing through the gas flow passage 213 is higher than that of the surrounding air and the pressure is lower, so that the ambient external air is mixed with the combustion gas supplied to the gas flow passage 213 through the first air inlet 217. This is done.]

In addition, the lower surface of the protruding body 215 is supported on the upper surface of the above-described supply box 110 through its protruding shape, and the upper surface satisfies the structure in which the lower surface of the nozzle fixture 220 is supported, so that the first air inlet ( 217) is always exposed to the outside, so that the inflow of outside air can be performed smoothly.

In addition, as shown, the nozzle fixture 220 is made of the same material as the above-described supply box 110 so that it can be molded into a donut shape of a hollow box as a whole, and the upper and lower surfaces thereof have second A through hole 223 is formed through a hole so that the aforementioned subnozzle 210 can be inserted therethrough.

In addition, a plurality of second air inlets 221 communicating with the inside of the nozzle fixture 220 are radially formed on the circumferential surface of the nozzle fixture 220, so that the combustion gas mixed with the combustion gas is primarily mixed with the outside for secondary mixing. allow air to be supplied.

To this end, the second through-holes 223 respectively formed on the upper and lower surfaces of the nozzle fixture 220 may be formed at positions opposed to the first through-hole 130 in the vertical direction. In particular, the nozzle fixture 220 The second through-hole 223 formed on the lower surface is inserted into the outer surface of the column tube body 211 in a shape-fitting manner to enable the sub-nozzle 210 to be fixed, and the second through-hole formed on the upper surface of the nozzle fixture 220 223 allows a gap D to be formed after the column tube body 211 is inserted.

Thus, in the first air inlet 217 formed in the sub-nozzle 210 and the gas flow path 213, external air and combustion gas are primarily mixed and supplied to the inside of the guide body 230, and the second air inlet ( 221) is introduced into the inside of the guide body 230 through the gap D formed on the upper surface of the nozzle fixture 220, and secondary mixing is performed with the primary mixed combustion gas in stages. It becomes possible to provide sufficient air required for combustion (see FIG. 6).

Since the inner diameter of the second through hole 223 is larger than the outer diameter of the column tube body 211, a gap D is formed, so that the outside air flows through the second through hole 223 and the gap D through the guide body ( 230) is supplied inside.

In addition, the guide body 230 is formed on the upper side of the above-described nozzle fixture 220 to provide a space for secondary mixing between the primary mixed combustion gas and another external air, and at the same time, a spark plug (not shown) It includes an inner ring 231 and an outer ring 233 as a configuration for inducing the spark to be collected when ignition is made by.

As shown, the inner ring 231 can be molded using the same material as the above-described supply box, and is formed in the shape of a ring as a whole to form a space on the inside together with the outer ring 233. .

In addition, the lower part of the inner ring 231 is fixedly installed with the upper part of the nozzle fixture 220 by welding or the like.

As shown, the outer ring 233 can be molded using the same material as the inner ring 231, and is molded to have a ring shape as a whole in the same way as the inner ring 231.

At this time, the inner ring 231 is formed to have a larger upper diameter than the lower diameter, but the outer ring 233 is bent so that the upper diameter is smaller than the lower diameter, so that the upper opening width W1 of the guide body 230 is It is preferable to satisfy a smaller structure compared to the lower opening width W2.

Thus, when the combustion gas, which is primarily mixed in each sub-nozzle 210, is exhausted to the inner space of the guide body 230, the outside air introduced through the second air inlet 221 is again passed through the gap D. Secondary mixing is performed in the corresponding space portion, and ignition is made while exhausting to the upper side opening width W1 of the guide body 230, so that the flame is collected and sufficient external air required for combustion is supplied at the same time (Fig. see 6).

As described above, the burner 1 according to the present invention has a sufficient separation distance between the upper end of each subnozzle 210 in the vertical direction and the opening width at the upper end of the guide body 230 differently from the prior art, as well as each other. After the air introduced into the first air inlet 217 and the second air inlet 221 located at different locations is primarily mixed with the combustion gas in the sub-nozzle 210, the primarily mixed combustion gas is again As the primary mixing is performed in the inner space of the guide body 230 and ignition is made, the flame is collected and combustion is effectively performed.

As described above, the present invention has been described by specific details such as specific components and limited embodiments and drawings, but these are provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , Those skilled in the art in the field to which the present invention belongs can make various modifications and variations from these descriptions.

Therefore, the spirit of the present invention should not be limited to the described embodiments, and it will be said that not only the claims to be described later, but also all modifications equivalent or equivalent to these claims belong to the scope of the present invention. .
