Description

DETAILED DESCRIPTION OF THE INVENTION In addition to the conventional heating by convection heat, the present invention heats the food with a cervical radiator that uses far-infrared radiant material that emits a large amount of radiation heat, and heats the food to the inside of the food. The purpose is to heat the food more thoroughly and to speed up the cooking time.

A typical conventional gas oven has an oven box 1 as shown in FIG. 4, and a burner 2 is located at the bottom of the oven box 1.

A heat shield plate 4 is attached to the bottom plate 3 that is lit by the flame of the burner 2, and the food to be cooked is mainly heated by convection heat from the burner 2, and the heat from the bottom plate 3 is used to heat the food under the food. This prevented it from getting too burnt. Therefore, there was a drawback that the important heat was intentionally reduced, and the cooking time was lengthened due to this.

The present invention eliminates the drawbacks of the conventional method by making it possible to fully utilize eel radiant heat in addition to the convection heat generated by the combustion 9E heat of the burner for cooking food.

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 3. A burner 7 is located in the lower part 6 of the oven box 5, and a lower metal corrugated sea bream projectile 8 is provided above the burner 7.

The open box 5 is provided with shelves 9, 9', 9'', an upper burner 10 is installed inside the upper part, and an upper metal corrugated Korean projector 111a, 11- which is divided into left and right sides is placed above the burner 10. b exists.

Lower metal corrugated exposure body 8 and upper metal corrugated neck body 1
On the side facing the food 1-a and 11-b, that is, on the wave surface facing the inside of the oven box 5, Zhco2, Ti〇2
, Si〇2.Sic, Cr2〇3, Ca〇, Mg○, Rei 203, etc., are coated with a coating A of a far-infrared emitting substance.

The opposite sides of the radiators 8, 11-a, and 11-b are coated with an aluminum film B having good thermal conductivity. The outer wall of the oven box 5 is covered with a heat insulating material 12, and the upper surface is provided with a plurality of exhaust holes 13, and the lower part 6 is provided with a plurality of combustion intake holes 14. An exterior bottom plate 16 is screwed to an exterior box 15 located on the outer periphery of the oven box 5, and a top surface 17 of this exterior box 15
is provided with an exhaust hole 18, and this exhaust hole 18 is connected to the exhaust hole 1.
8' is reversed by the exhaust hole frame 19.

The exhaust hole 13 and the exhaust hole 18 are communicated through an exhaust pipe 201.

21 is a gas control unit; 22 and 23 are nozzle mounting units that are part of the gas supply unit to the upper burner 10 and the lower burner 6, respectively;
4 and 25 are nozzles.

The wave-shaped striped projectors 8, 11-a, 11-b are coated with Z2, Ti02, Si02 on one surface of a base material 26 made of heat-resistant steel.
, SIC, Ca0, Mg○, N203, Cr203, etc., is coated with a coating A of a far-infrared emitting material with a thickness of 3 to 30 mm, and the other side is coated with an aluminum coating B that improves heat conduction.

When the lower burner 6 and the upper burner 0 are ignited and burned, the corrugated projectiles 8, 111a, 111b,
is heated, and the food in the oven box 5 is heated by far infrared rays, and the exhaust heat from the lower burner 6 enters the oven box 5 and heats the food with convection heat.

In conventional ovens, the exhaust heat from the burner 2 enters the oven box 1, heats the food with convection heat, and the burner 2
Since the bottom plate 3 is heated by the flame and exhaust heat, a heat shield plate 4 is provided to prevent the food from being burnt too much due to the infrared heat radiated from the bottom plate 3, which is mainly infrared radiation of less than 3 fm. and
As a result, the heat from burner 2 could not be used favorably.

However, in this embodiment, a lower metal corrugated fin projector 8 is arranged above the lower burner 7, and an aluminum coating B is formed on the side that directly receives the heat of the burner 7 to improve heat conduction. 8
The heat distribution over the entire surface of the body is improved, and local deformation of the neck body 8 due to thermal strain is prevented by making it wave-shaped. In the case of the upper metal corrugated projectors 111a and 111b, the flame goes upward, so the flame and exhaust heat mainly heats the far-infrared emitting material coating A, but it is important to make the heat conduction uniform. In order to perform this with aluminum coating B, its thickness is increased.

In addition, since the fin projectors 8, 11-a, 11-b are arranged above and below the oven box 5, the food to be cooked is 3 m to 30 m long.
By receiving far-infrared rays, it is possible to sufficiently heat the food from the top to the inside without damaging the surface of the food, and the cooking time can be shortened. Also, although it is proportional to the area of the Korean projector, the effect can be expected by making it waveform.

Furthermore, if the infrared rays are less than 3 mF, the surface of the food will burn, but far infrared rays of 3 to 30 rms will heat the food 10 to 50% faster to the inside without burning the surface, which is a good effect. . As described above, the present invention provides a neck body whose surface facing the food is coated with a far-infrared emitting material and whose other surfaces are coated with a material having good thermal conductivity, in the vicinity of the burner installed in the oven box. This is of great industrial value as it provides a cooking device that can satisfactorily heat the food to the inside without burning or drying the surface of the food.
