The steaming chambers 2 are separated by vertical partitions 6. The vertical partitions 6 are provided with a plurality of communication ports 11, which correspond to the air distribution layer 10. The air distribution layer 10 is connected to the steam flow channel 4 through the corresponding communication ports 11. The steam flow channel 4 is provided with a plurality of guide plates 12, which correspond to the communication ports 11 one by one. The middle of the guide plates 12 is installed in the steam flow channel 4 through a rotating shaft 13, and the rotating shaft 13 is driven to rotate by a motor located outside the box body 1. The air distribution layer 10 is provided with a plurality of temperature sensors 14 respectively. The electric steaming box also includes a PLC controller, and the motor and the temperature sensor 14 are connected to the PLC controller respectively. The heater 5 in the steam generating chamber 3 heats the water to form high-temperature water vapor. Part of the water vapor enters the steaming chamber 2 through the steam hole 7 to heat the bottom layer of the steaming plate 8. The remaining water vapor enters the steam flow channel 4 to form high-temperature and high-pressure water vapor. The high-temperature and high-pressure water vapor enters the air distribution layer 10 through the communication port 11 to heat the upper and lower steaming plates 8. By rotating the guide plate 12, the steam flux in the steam flow channel 4 can be adjusted, thereby guiding the steam into the corresponding air distribution layer 10, so as to achieve the purpose of individually controlling the temperature of each air distribution layer 10. The PLC controller controls the motor to rotate and adjust the angle of the guide plate 12 according to the data of the temperature sensor 14.

[0015] Furthermore, an air guide structure is installed in the air distribution layer 10, and the air guide structure includes two air guide plates 15, and an air guide channel 16 is formed between the two air guide plates 15.

One of the connecting shafts 18 is connected to a rotating motor after extending out of the box body 1, and the rotating motor is connected to a PLC controller. The air guide structure can change the steam flow direction inside the air distribution layer 10, and the temperature inside the air distribution layer 10 can be uniform by continuously adjusting the air guide structure.

[0016] Furthermore, an air pressure sensor 19 is installed in the connecting port 11, and at least three temperature sensors 14 are installed in the air distribution layer 10. The three temperature sensors 14 are arranged in sequence in the air distribution layer 10, and the air pressure sensor 19 is connected to the PLC controller. The air pressure sensor 19 can sense the air flow pressure in the corresponding connecting port 11, provide the parameters of the steam entering the air distribution layer 10, and facilitate the PLC controller to control the corresponding guide plate 12 to adjust the air intake. The temperature sensor 14 can sense the temperature data at different positions in the air distribution layer 10, and facilitate the PLC controller to control the air guide structure to change the flow direction of the steam entering the air distribution layer 10, so as to prevent the local temperature of the air distribution layer 10 from being too high for a long time, resulting in uneven heating of the rice steaming plate 8.

[0017] Furthermore, a movable cover plate 20 is placed on the partition plate 6, and a plurality of docking holes 21 are provided on the movable cover plate 20, and the docking holes 21 correspond to the steam holes 7 one by one. A push rod 22 is fixedly connected to the movable cover plate 20, and one end of the push rod 22 extends out of the box body 1 and is connected to an electric push rod 26, which is connected to a PLC controller. The movable cover plate 20 is pulled by the electric push rod 26, so that the docking holes 21 are staggered with the corresponding steam holes 7, so that the flow rate of steam entering the bottom layer of the rice steaming plate 8 can be controlled.

[0018] Furthermore, a condensation chamber 23 is provided above the steam generating chamber 3, and the upper end of the steam flow channel 4 is connected to the condensation chamber 23, and a water receiving tray 24 is placed in the condensation chamber 23. The condensed water formed by the small amount of steam at the upper end of the steam flow channel 4 after being cooled and condensed drops on the water receiving tray 24 for collection, thereby reducing the condensed water from directly flowing back from the steam flow channel 4 to affect the rotation of the guide plate 12, and reducing the condensed water from entering the air distribution layer 10 through the connecting port 11 to affect the food in the rice steaming tray 8.

[0019] Furthermore, a plurality of condensation columns 25 are provided in the condensation chamber 23, the condensation columns 25 are fixedly connected to the housing 1, and the condensation columns 25 are located above the water receiving tray 24.
