The conventional burner assembly configured as described above operates as follows.

First, when the user places the heating element on the upper surface of the ceramic glass 20 and operates the burner, fuel gas and air are supplied into the burner port 302 through the mixing tube 304 to be mixed, and fuel gas and air Mixed gas is blown out through the burner mat 303.

At the same time, the mixed gas is ignited by the ignition spark generated by the predetermined ignition and salt detection means, and combustion occurs on the surface of the burner mat 303, and the radiation wave caused by this combustion penetrates the ceramic glass 20 Cooking is performed by heating a heating body.

At this time, the combustion gas generated in the burner housing 301 is discharged to the exhaust duct 50 through the connection duct 305.

However, since the conventional gas radiation cooker flows toward the connecting duct 305 through the burner mat 303 and the combustion gas is low when the combustion gas is discharged from the burner housing 301 of the burner assembly. The discharged combustion gas acts as a heat load on the burner mat 303, so that the carbon monoxide (CO) concentration increases inside the burner housing, while the air inflow decreases, resulting in incomplete combustion and heat loss. there was.

Accordingly, an object of the present invention is to provide a gas radiation cooking apparatus capable of minimizing heat load in a process of discharging combustion gas inside a burner housing.

According to an embodiment of the present invention for achieving the above object, a burner housing in which an exhaust flow path through which combustion gas is discharged is formed, and a burner housing installed in the housing and having one side portion communicating with the exhaust flow path of the housing; In the gas radiation cooking apparatus provided at the bottom of the burner housing having a burner pot (burner pot) to form a space to be burned while the gas and air mixed gas is supplied, and the glass shielding the upper portion of the burner housing, A gas radiation cooking apparatus is provided, wherein a stepped portion having a predetermined height is formed at a portion of the lower surface of the burner housing communicating with the exhaust passage.

According to another embodiment of the gas radiation cooking apparatus of the present invention, a housing having an exhaust flow path through which combustion gas is discharged, a burner housing provided inside the housing and having one side portion open to communicate with the exhaust flow path of the housing; In the gas radiation cooking apparatus provided at the bottom of the burner housing having a burner pot (burner pot) to form a space to be burned while the gas and air mixed gas is supplied, and the glass shielding the upper portion of the burner housing, The lower surface of the burner housing is characterized in that the height is formed lower than the exhaust passage.

Hereinafter, preferred embodiments of the gas radiation cooking apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 show a gas radiation cooker according to the present invention, the gas radiation cooker of the present invention includes a housing 10, a plurality of burner assemblies 30 installed inside the housing 10, Ceramic glass 20 coupled to the housing 10 to shield the upper portion of the burner assembly 30, and the exhaust duct 50 to induce the combustion gas burnt from the burner assembly 30 to the outside It is composed.

The burner assembly 30 is installed directly under the ceramic glass 20, and a burner housing 31 having an upper end thereof shielded by the ceramic glass 20, and a screw 36 at a lower portion of the burner housing 31. A burner port 32 coupled to each other by a fastening means, such that the fuel gas and air are supplied, and a burner mat 33 seated on the burner port 32 to burn the mixed gas, and the burner And a mixing tube 34 for supplying a mixed gas of fuel gas and air into the port 32.

The burner housing 31 has one side portion communicating with the exhaust duct 50 via the connection duct 35.

On the other hand, the burner housing 31 and the connection duct 35 is in communication with the stepped portion 36 is formed to have a predetermined height to guide the exhaust gas to the upper side, the stepped portion 36 is burner The housing 31 and the connection duct 35 may be integrally formed over the entire communicating portion, or as shown in FIG. 4, a plurality may be divided at regular intervals.

The gas radiation cooker configured as described above is operated as follows.

When the user places the food on the upper surface of the ceramic glass 20 to cook food and operates the burner, fuel gas and air are supplied into the burner port 2 through the mixing pipe 34 under the control of the microcomputer. The mixture is mixed, and the mixed gas of fuel gas and air is blown out through the burner mat 3.

At the same time, the mixed gas is ignited by the ignition spark generated by the predetermined ignition and salt detection means, and combustion occurs on the burner mat 33 surface.

When the combustion is performed as described above, the pressure is increased due to the generation of the combustion gas while the air and the gas are continuously supplied to the burner assembly 30, so that the combustion gas inside the burner housing 31 is connected to the duct 35. It is discharged to the outside through the exhaust duct (50) at this time, because the stepped portion 36 is formed between the burner housing 31 and the connection duct 35 at a predetermined height, combustion in the burner housing 31 As the gas rises upward, the gas is discharged to the connection duct 35 through the space between the upper end of the step portion 36 and the ceramic glass 20.

Therefore, it is possible to prevent the combustion gas discharged from the burner housing 31 from increasing the heat load while passing through the burner mat 33 surface, and increase the air intake amount.
