Description

Burner assembly for gas copy cooker {Burner assembly for gas burners of radiant heating type}

The present invention relates to a gas radiation cooker, and more particularly to a burner assembly.

BACKGROUND ART In general, a gas radiation cooker is a cooking device in which cooking is performed by heating a heated object by radiation generated when heating a radiator by combustion of a mixed gas mixed with fuel and air.

1 is a schematic diagram of a conventional gas radiation cooker.

That is, the conventional gas radiation cooker is configured to include the oven unit 10 and the top burner unit 20.

Here, the top burner unit 20 includes the burner assembly of FIGS. 2 and 3, and the structure of the conventional burner assembly will be described below with reference to FIGS. 2 and 3.

First, the conventional burner assembly is largely comprised of a burner housing 21, a glass 22, a mixing pipe 23, a burner port 24, and a burner mat 25.

The burner housing 21 is configured to form a combustion chamber of a predetermined size where substantial combustion takes place.

In this case, a communication port 21a for mounting with the burner port 24 is formed at the center of the bottom surface of the burner housing 21, and the exhaust flow of the exhaust gas is guided at the circumferential surface of the burner housing 21. An exhaust passage 26 to communicate is formed. In addition, an exhaust port 26a is formed on the exhaust passage 26.

The glass 22 is mounted on the open upper surfaces of the burner housing 21 and the exhaust passage 26 to shield the combustion chamber formed by the burner housing 21 from the external environment.

At this time, the cooking vessel is seated on the upper surface of the glass 22, and serves to heat the cooking vessel by receiving the combustion heat generated while burning in the combustion chamber.

In addition, the mixing tube 23 is a tube in which fuel and air are introduced and mixed with each other, and are in communication with the burner port 24.

The burner port 24 is a portion in which the mixed gas introduced through the mixing pipe 23 is stored, and the bottom thereof is closed and the upper portion thereof is opened.

At this time, the opened upper portion of the burner port 24 is mounted to communicate with the internal space of the burner housing 21.

The burner mat 25 is mounted on the burner port 24 and is configured to combust the mixed gas provided from the burner port 24.

At this time, the burner mat 25 performs a role of a radiator generating radiation while performing surface combustion.

Referring to the operation of the burner assembly configured as described above are as follows.

First, when the user performs an ignition operation with the heating object placed on the upper surface of the glass 22, fuel and air are introduced into the mixing tube 23, respectively, and are mixed with each other while passing through the mixing tube 23. .

In addition, the mixed gas is introduced into the burner port 24 communicating with the mixing pipe 23 and is blown into the combustion chamber of the burner housing 21 while passing through the burner mat 25.

At the same time, the mixed gas is ignited and combusted by an ignition spark generated by an ignition means not shown.

At this time, the mixed gas is burned on the surface of the burner mat 25, and the burner mat 25 generates radiation by heating by the combustion.

Subsequently, the radiation is transmitted through the glass 22 to heat the object to be cooked.

However, the structure of the above-described conventional burner assembly has a problem that the discomfort in assembly is caused because the burner port 24 is tightly coupled to the outer bottom of the burner housing 21.

That is, when the burner port 24 is to be coupled to the burner housing 21, the fastening hole for screwing is matched with the burner port 24 in close contact with the bottom of the burner housing 21, and then screwing is performed. Because of this, working inconvenience is caused.

In particular, the burner port 24 is caused by the inconvenience that had to be supported by the operator to maintain the state in close contact with the bottom of the burner housing 21 has caused a decrease in assembly efficiency.

In particular, since the coupling between the burner housing 21 and the burner port 24 is a fastening by the screw, only the portion to be screwed is in close contact by point contact, and other parts are not closely contacted and a gap is generated. In addition, the gap has caused a problem of leakage of combustion gas.

At this time, since the portion of the combustion gas leak is not the combustion chamber but the interior of the gas radiation cooker, there is a problem that the risk of fire due to the leaked combustion gas is considerably greater.

The present invention has been devised to solve the various problems described above, the object of the present invention is to facilitate the coupling between the burner port and the burner housing, and to minimize the gap generated during the mutual coupling to prevent the leakage of combustion gas We wanted to provide a burner assembly with a new structure to make it possible.

A burner assembly for a gas radiation cooker is provided.

Here, the auxiliary bracket is characterized in that the burner housing and the burner port and the burner mat is formed so as to have a width enough to cover all the combined portion.

In addition, the blocking portion of the auxiliary bracket is characterized in that a plurality of exhaust holes are formed to enable the smooth exhaust of the exhaust gas.

Hereinafter, with reference to Figures 4 and 5 attached to a preferred embodiment of the present invention that the above object can be specifically realized as follows.

First, the burner assembly according to the embodiment of the present invention has a burner housing 210, a glass 220, a burner port 240, a burner mat 250, and an auxiliary bracket as shown in FIGS. 4 and 5. And 270.

Here, the burner housing 210 is configured to form a combustion chamber in which substantial combustion is performed, and an upper portion of the burner housing 210 is formed to be open, and a communication hole 211 communicating with a bottom space is formed at an inner central portion thereof.

At this time, the open upper surface of the burner housing 210 is shielded by the glass 220.

The glass 220 shields the combustion chamber formed by the burner housing 210 from the external environment, and a cooking vessel is mounted on an upper surface thereof to receive the heat of combustion generated during combustion in the combustion chamber to heat the cooking vessel. Play a role.

In addition, a recess 212 recessed by a predetermined height toward the bottom is formed at an inner circumferential portion in which the communication port 211 is formed among the portions of the burner housing 210.

In addition, the burner port 240 is mounted through the communication port 211 of the burner housing 210 and the upper circumference of the burner port 240 is seated in the depression of the burner housing 210 in an outwardly bent state. The mixed gas is introduced while passing through the pipe 230.

At this time, the upper portion of the burner port 240 is formed to be opened.

In addition, a concave recess 241 for seating the burner mat 250 is bent inside the upper surface of the burner port 240.

The coupling structure between the burner housing 210 and the burner port 240 as described above allows the fastener to proceed with the burner port 240 mounted on the circumference of the communication port 211 of the burner housing 210. The assembly is made to be convenient.

In particular, even if the gas introduced into the burner port 240 leaks through a gap formed at the coupling portion between the burner housing 210 and the burner port 240, the leaked gas is introduced into the combustion chamber, so Safety problems caused by this can be prevented.

In addition, the burner mat 250 is seated in the recess groove 241 of the burner port 240, and surface combustion is performed by the mixed gas supplied into the burner port 240.

In addition, the auxiliary bracket 270 is such that the coupling between the burner housing 210 and the burner port 240 and the burner mat 250 can be coupled in close contact while making a surface contact rather than a point contact. Play a role.

That is, when the auxiliary bracket 270 is screwed together with the coupling portion between the burner housing 210 and the burner port 240, a point contact is made between the auxiliary bracket 270 and the burner housing 210. The surface contact is made between the burner housing 210 and the burner port 240 by the adhesion between the auxiliary bracket 270 and the burner housing 210.

The auxiliary bracket 270 is formed to have a substantially ring shape and has a blocking portion 271 that is bent upward by a predetermined height along its outer circumference.

At this time, the auxiliary bracket 270 is preferably formed to have a width enough to cover all the combined portion between the burner housing 210 and the burner port 240 and the burner mat 250.

That is, the burner housing 210 and the burner port 240 may be coupled to each other using the auxiliary bracket 270, and the burner mat 250 may be removed.

In addition, the height of the blocking portion 271 of the auxiliary bracket 270 is lower than the interval between the inner upper surface of the burner housing 210 and the glass 220, that is, the height of the combustion chamber, but is approximately 1/2 or more of the interval. It is preferable to be formed at a height high enough to be.

This is because when the height of the blocking part 271 is formed to be 1/2 or less than the height of the combustion chamber, the heat of combustion may be exhausted immediately without sufficiently flowing in the combustion chamber, thereby causing a decrease in thermal efficiency. to be.

Of course, by making the height of the blocking unit 271 too high, it should be possible to prevent the occurrence of combustion failure due to the exhaust failure of the exhaust gas.

In addition, the thickness of the blocking portion 271 is preferably formed of a thin thin plate.

This, when the blocking portion 271 is formed of a thin plate can be faster than the heat conduction, thereby improving the heat transfer performance to the glass 220.

In addition, it is more preferable that a plurality of exhaust holes 271a are formed on the surface of the blocking part 271 so as to enable smooth exhaust of the exhaust gas.

That is, since the combustion failure may occur due to the inability to exhaust the exhaust gas smoothly due to the blocking part 271, a plurality of exhaust holes may be provided in the blocking part 271 to allow the exhaust gas to be exhausted. It is more preferable to form 271a).

In particular, when a plurality of exhaust holes 271a are formed on the surface of the blocking part 271, heat exchange efficiency between the heat of combustion and the blocking part is further improved, thereby further improving heat transfer performance to the glass 220. .

Hereinafter, the cooking process by the burner assembly of the above-described embodiment of the present invention will be described.

First, when the user performs the ignition operation with the heating object, ie, the cooking vessel, placed on the upper surface of the glass 220, fuel and air flow into the mixing tube 230, respectively, and pass through the mixing tube 230. Are mixed with each other during the process.

In addition, the mixed gas is introduced into the burner port 240 in communication with the mixing pipe 230 and is blown into the combustion space of the burner housing 210 while passing through the burner mat 250.

At the same time, the mixed gas is ignited by the ignition spark generated by the ignition means not shown and burned on the surface of the burner mat 250.

In addition, combustion heat is generated by combustion occurring on the surface of the burner mat 250, and the combustion heat is provided to the glass 220 while raising the inside of the combustion chamber to heat the cooking vessel.

At this time, the combustion heat is exhausted by the blocking portion 271 of the auxiliary bracket 270 mounted along the circumference of the communication port 211 of the burner housing 210 so that the exhaust passage 261 is formed immediately. It is not discharged to 260 and flows to the upper portion of the combustion chamber.

Accordingly, the glass 220 may be provided with the maximum effect of the heat of combustion flowing in the combustion chamber.

In addition, since the blocking part 271 of the auxiliary bracket 270 receives the heat of combustion in the combustion chamber, a high temperature is achieved during combustion, and thus the temperature in the combustion chamber is further increased by reheating the combustion heat. As a result, the thermal efficiency provided to the glass 220 can be further improved.

In particular, the plurality of exhaust holes 271a formed in the blocking portion 271 of the auxiliary bracket 270 are heat-exchanged while the exhaust gas and the heat of combustion pass through, so that the reheating effect of the blocking portion 271 may be more smoothly performed. Will be.

In addition, the exhaust gas flowing in the combustion chamber by the series of processes described above is a little through the gap formed between the blocking portion 271 and the glass 220 and each exhaust hole 271a formed in the blocking portion 271. By exhausting, smooth combustion is possible.

As described above, the burner assembly according to the embodiment of the present invention allows the coupling between the burner housing and the burner port to be made by the auxiliary bracket so that the mixed gas introduced into the burner port is formed at the coupling portion between the burner port and the burner housing. Through the gap that has become an effect that can prevent the conventional problem that leaked to the outside of the combustion chamber.

In particular, the burner assembly according to the embodiment of the present invention also has the effect that it is possible to minimize the heat loss by the blocking portion of the auxiliary bracket.
