The infrared ray generating assembly 34 and the cover plate 48 constitute a heating assembly of a heat source for heating the cavity 10 by generating heat energy, thereby heating the food material from top to bottom to uniformly heat the surface of the food material.
With the above structure, the heating method of the kiln 100 of the present invention can be performed, which comprises the following steps:
first, the person operates the knob 32 of the gas control valve and the ignition switch 34 to control the burner 42 to generate flame. Referring to fig. 7 and 10, after the flame is generated, the infrared ray generating assembly 54 is heated, so that the infrared ray generating assembly 54 generates infrared rays. In this embodiment, the flame acts on the infrared ray generation net 542, so that the two radiation surfaces 542a and 542b of the infrared ray generation net 542 radiate infrared rays, and the infrared rays radiated from the radiation surface 542a close to the cover plate 48 are irradiated onto the carrier plate 282 through the holes 484 of the cover plate 48, thereby having a larger heating area. The infrared rays radiated from the radiation surface 542b near the reflection plate 544 are reflected by the reflection surface 544a of the reflection plate 544 toward the infrared ray generation net 542 and are irradiated onto the carrier 282 through the meshes of the infrared ray generation net 542 and the holes 484 of the cover plate 48, so as to enhance the intensity of the infrared rays irradiated onto the carrier 282. Since the axis i of the burner 42 and the radiation surface of the infrared ray generation net 542 form an angle of 100 to 135 degrees, the flame can be uniformly applied to the radiation surfaces 542a and 542b of the infrared ray generation net 542, and the optimum infrared ray radiation effect can be achieved. The flame generated by the burner 42 also acts on the cover plate 48, so that the cover plate 48 generates infrared rays and also enhances the intensity of the infrared rays irradiated on the carrier plate 282.
The temperature of the infrared generating element 54 is maintained at 900-1100 ℃, and the shielding of the cover plate 48 makes the infrared rays passing through the holes 484 of the cover plate 48 have a preferred wavelength range of infrared rays, the preferred wavelength range is 4-8 μm, and the infrared generating element has a better penetrating power for the food material heated on the support plate 282 to heat the interior of the food material. The outer surface of the cover plate 48 (the surface facing away from the infrared ray generating assembly 54) has a temperature of between 600 and 800 ℃.
The flame generated by the burner 42 is blown out through the holes 484, 522 of the two cover plates 48, 52, and an open fire is formed at the top of the middle section 126, which is used to heat the surface of the food material, such as to coke the surface of the food material, thereby turning golden yellow. Thus, the combustion device 40 can generate a larger heating area to achieve the purpose of uniform heating and increase the heating efficiency.
During gas combustion, coke is generated on the infrared generation component 54, and steam generated during gas combustion is heated to form superheated steam, when the superheated steam passes through the coke which is hot at 900-1100 ℃ on the infrared generation component, the superheated steam will react to generate water gas, and the water gas contains hydrogen and carbon monoxide to generate combustion supporting effect.
For example, the reaction of water vapor through coke at elevated temperatures to produce water gas is as follows:
C+H2O→H2+CO-113.4KJ。
where the heat energy is-113.4 KJ, representing an endotherm, but the H2 and CO formed with the steam formed by combustion will be exothermic in the following reaction:
CO+H2O→H2+CO2+42.71KJ;H2+1/2O2→H2O+237.4KJ。
the total heat energy released is 280.11KJ, and 166.71KJ of heat energy is still generated by deducting the-113.4 KJ dissipated. It is understood that the superheated steam has an effect of improving the heating efficiency by the water gas generated from the coke on the infrared ray generation unit 54. Therefore, the effect of saving the gas consumption can be achieved. The infrared ray generating component 54 is located between the two cover plates 48, 52, so that the infrared ray generating component 54 can be maintained at a temperature of 900-1100 ℃ by the cover plates 48, 52, and the gas consumption is limited, thereby providing the temperature required for generating the water gas. The concave of the cover plates 48, 52 away from the infrared ray generating component 54 can intensively reflect part of the heat energy toward the infrared ray generating component 54, thereby having better effect of maintaining temperature. The single cover plate 48 also helps to maintain the temperature of the infrared generating assembly 54 at 900-1100 deg.C, however, the required amount of gas will be higher than the two cover plates 48, 52.
The temperature of the superheated steam is above about 300 ℃, the water molecules of the superheated steam are changed into smaller steam, the superheated steam can also be used for heating food materials, the food materials can penetrate through food, fat is dissolved at high temperature, the heating efficiency of the food materials is improved, and the steam emitted by the food materials is also heated into superheated steam to further enhance the heating efficiency.
The combustion device 40 creates a high temperature zone at a higher position, so that the hot air flow formed by combustion (i.e. the hot air flow formed by the heat energy generated by the heating element of the heat source) is guided downwards by the wall surface at the top of the front section 122 of the furnace chamber 12, which is beneficial to flowing back to the combustor 42, and reducing the heat energy loss. In addition, the hot air flows back and simultaneously external air is introduced from the inlet 14 to supplement combustion air. By mixing the hot air flow with the external air, the temperature of the air flow flowing back to the burner 42 can be raised, and the cold air is prevented from flowing back to the burner 42 directly, thereby reducing the heat energy loss and increasing the heating efficiency.
In addition, the heat insulation structure 24 covers the cavity 16, so as to maintain the temperature in the furnace chamber 12, reduce the heat energy of the combustion device 40 from being dissipated through the cavity 16, help to maintain the temperature of 900-1100 ℃ of the infrared generating assembly 54, and reduce the consumption of gas. The heat accumulation member 22 will remove a portion of the heat energy from the top of the front section of the furnace chamber 12, so that the temperature of the top of the front section 122 of the furnace chamber 12 is relatively lower than the temperature of the top of the middle section 126, thereby assisting in pushing down the hot gas flow. The effect of improving the hot air flow to flow back to the burner 42 increases the heating efficiency, and also helps to maintain the temperature of 900-1100 ℃ of the infrared ray generating component 54, and reduces the consumption of gas.
By the heating method, the food in the oven cavity can be fully heated, and the consumed gas quantity can be reduced.
It should be noted that the gap a1 between the first portion 502 and the second portion 504 of the supporting plate 50 and the inner wall 124a of the rear section 124 of the cavity 12 and the gap a2 on the top wall of the rear section 124 can generate laminar airflow to pull the reflowing hot air upward, so as to better circulate the hot air in the cavity 12.
The excess hot air flow is exhausted from the air outlet 164a through the air guide structure 18 and the exhaust duct 20. In the exhaust process, the external cold air is drawn from the inlet 362a of the front panel 362 and the inlet 14 to the air guide structure 18 and the exhaust duct 20 through the air outlet 164a, so as to lower the temperature of the front panel 362 and the temperature of the exhaust duct 20, thereby preventing people from touching the front panel 362 and burning the exhaust duct 20. Because the heat storage part 22 is contacted with the air guide structure 18, partial heat energy of the heat storage part 22 can be transferred into the air guide structure 18 to heat the exhaust channel E, so that heat transpiration is formed, upward pulling force is generated, the exhaust speed of hot air flow is accelerated, the exhaust efficiency is improved, and the hot air flow circulation effect in the furnace cavity is increased. The upwardly inclined guide plate 182 can also increase the flow guiding effect, so as to further increase the exhaust efficiency. In addition, the increased velocity of the hot air flow exhaust also increases the velocity of the cool air drawn into the air guide structure 18, which further reduces the temperature of the front panel 362 and the exhaust duct 20. The location of the exhaust duct 20 above the front section 122 of the chamber 20 also allows for a shorter exhaust path and faster exhaust flow.
