The height difference sucks and discharges the high-temperature water vapor in the heating cavity to the air, quickly hardens the surface of the food and seals the moisture inside the food, realizes the hardening of the surface of the food, and maintains the soft taste of the food inside; 5) The outlet of the exhaust pipe is higher than the inner wall of the upper cover, the lower end of the inner wall of the exhaust pipe is connected to the inner wall of the upper cover, and the upper end of the exhaust pipe is connected with the outside to form a natural exhaust chimney, which will heat the water vapor in the inner cavity Slightly sucked out into the air; The water vapor in the heating cavity is discharged by micro-suction, and the heat dissipation rate is lower than the heating rate of the heater in the main body, so that the temperature in the heating cavity can be kept rising when the food is heated; The heating inner cavity is composed of the air inlet and the exhaust pipe or exhaust hole to form a heating system structure with natural circulation exhaust. The heating inner cavity is heated by the upper and lower heaters to heat the moisture in the food into the The heating cavity expands into water vapor, and when the water vapor is on the surface of the heater, it vaporizes instantly, accelerating the water vapor to discharge excess food moisture along the exhaust pipe or vent hole, accelerating the speed of food heating, and preventing water vapor Condensate into water droplets and flow back or drip back into the food container, at least prevent a part of the water vapor from condensing into water droplets and flow back or drop back into the food container, quickly harden the surface of the food and seal the moisture inside the food, and realize the hardening of the food surface , the interior keeps the food soft and soft; 6) Through the expansion of water vapor in the heating cavity, the natural circulation exhaust heating system structure realizes the important part of heat isolation in the heating cavity without leakage, increases the heat of food, maintains constant temperature, continuous heating, and constant temperature of food It is realized by heating the temperature controller on the outer body of the inner cavity to quickly harden the surface of the food and seal the moisture inside the food, so as to harden the surface of the food and keep the soft taste of the food inside; 7) When the exhaust pipe or the exhaust hole is exhausted, the area of the water vapor staying on the inner wall of the upper cover is smaller than the area of the inner wall of the upper cover. It can be seen that the area of the water vapor staying on the inner wall of the upper cover does not exceed 1/ of the area of the inner wall of the upper cover 2. At least during the heating time of the rear end when the food is heated, it can be seen that the area where the water vapor stays on the inner wall of the upper cover does not exceed 2/3 of the area of the inner wall of the upper cover; The upper heater is set at the position where the water vapor rises. The upper heater blocks and heats the water vapor to vaporize, quickly hardens the surface of the food and seals the moisture inside the food, so as to harden the surface of the food and maintain the soft taste of the food inside; 8), the more exhaust pipes or vent holes, the larger the exhaust, the faster the exhaust; the fewer exhaust pipes or vent holes, the smaller the exhaust, the slower the exhaust; the cooling speed of the exhaust pipe or vent steam is less than The heating speed of the upper and lower heaters, the local minimum temperature inside the heating cavity is not lower than 120 degrees; The local maximum temperature inside the heating cavity is not lower than 200 degrees, quickly hardens the surface of the food and seals the moisture inside the food, realizes the hardening of the surface of the food, and maintains the soft taste of the food inside; 9) The farther the distance between the bottom of the upper heater and the bottom of the food container, the slower the heating of the lower part of the food; the larger the volume of the heated food, the slower the reheating or vaporization of the water vapor in the lower part of the food, and the slower the natural discharge of water vapor; The closer the bottom of the upper heater is to the bottom of the food container, the faster the lower part of the food is heated, the faster the water vapor reheats or vaporizes, and the faster the water vapor is naturally discharged; The bottom of the upper heater directly heats the upper part of the food. The faster the heated water vapor is reheated or vaporized, the faster the water vapor is discharged, and the surface of the food is quickly hardened to seal the moisture inside the food, so that the surface of the food is hardened and the inside maintain the soft texture of food; 10) The food container in the main body is tilted to drive the food to rotate, flip, shift, and be heated evenly; the side or bottom of the food container is provided with blocking blocks to push the food to rotate together, and the food is turned down or shifted when it reaches a high position , the food is heated evenly, and the multi-directional surface moisture of the food can be heated and overflowed into water vapor to be discharged into the air by natural convection, and the surface of the food can be quickly hardened to seal the moisture inside the food, so that the surface of the food can be hardened and the inside of the food can maintain a soft taste; The stirring device stirs the food to heat or the food container is tilted to drive the food to rotate, flip, and shift to drive the food to be heated evenly on multiple sides and to remove water vapor. The water vapor rises and is heated by the upper heater again. When the water vapor passes on the surface of the heater, it is instantly vaporized Quickly discharge the air, quickly harden the surface of the food to seal the moisture inside the food, realize the hardening of the surface of the food, and maintain the soft taste of the food inside; 11) The exhaust pipe naturally sucks the heat from the heater and the water vapor that heats the food in the food container out of the main body from bottom to top, and at the same time sucks relatively dry cold air into the food container through the air inlet or air intake gap The upper part of the opening is mixed with the water vapor in the heating cavity, and the cold air entering the heating cavity sinks naturally while extruding the water vapor and the heat flow rises and discharges out of the main body along the exhaust hole or exhaust pipe, or the water in the heating cavity is heated The heat flow of steam rises and discharges out of the main body along the exhaust hole or exhaust pipe, and at the same time drives the cold air entering the heating cavity to sink naturally and mix with the hot water vapor on the surface of the food to become hot water vapor along the exhaust hole or exhaust pipe Discharge the outside of the main body, quickly harden the surface of the food to seal the moisture inside the food, realize the hardening of the surface of the food, and maintain the soft taste of the food inside; 12) The upper heater accelerates the rise of water vapor and air, accelerates the decomposition of water vapor in the heated inner cavity and further micro-gasification, accelerates the discharge of water vapor into the atmosphere along the exhaust hole or the inner wall of the exhaust pipe, and quickly disposes of food The surface hardening seals the moisture inside the food, realizes the surface hardening of the food, and maintains the soft taste of the food inside; 13) When the oven is working in the previous period, there is more water vapor on the upper cover or the inner cavity. As the temperature in the heating inner cavity rises, the drainage speed of the steam system is accelerated by the natural circulation of the air flow, and the exchange of low temperature and high temperature is active. The water vapor on the upper cover or inner cavity is significantly reduced during working hours, and the area of water vapor on the upper cover or inner cavity is less than 10% of the area of the upper cover or inner cavity during working hours at the rear end until the work is completed; The upper part of the upper heater is bent inwards, and the middle part of the upper heater is arched upwards and hangs on the upper part of the opening of the food container to heat the sides and top of the food in multiple ways. As the food rotates in the food container, the food is bent inwards The upper heater scans and heats 360 degrees vertically or horizontally.
