[0014] The tray 13 has a rectangular tray body 15, the tray body 15 has a tray frame 17, and the tray body 15 has a plurality of heat radiation holes 16. The items to be baked are placed in the tray body 15, and the tray frame 17 is placed on the tray support 11 on both sides of the inner wall of the box.

[0015] Figure 4 , Figure 6This is a first embodiment of a heating plate, the heating plate has a rectangular heating plate body 18, the heating plate body 18 has a heating plate longitudinal side 21, a plurality of evenly distributed heating lamp beads 19 are arranged in the heating plate body, longitudinal lines A, B, C, D, E, F, G, H, I, G, K, transverse lines 1, 2, 3, 4, 5, 6, 7, 8, each longitudinal line 24 and the transverse line 23 The intersection position is a heating lamp bead installation position 22, each heating lamp bead installation position 22 is arranged with a heating lamp bead, the heating intensity of the heating lamp bead is adjusted by the size of the current, a temperature and humidity sensor 9 and the heating lamp beads in an area are electrically connected to the same circuit board of the control module at the same time, that is, the temperature and humidity data obtained by the temperature and humidity sensor 9 are used to adjust the size of the current of the heating lamp beads in an area through the control module, thereby adjusting the heating intensity of the heating lamp beads. For example, longitudinal lines A, B, C, D, E, and transverse lines 1, 2, 3, 4 are the first area; longitudinal lines F, G, H, I, G, K, and transverse lines 1, 2, 3, 4 are the second area; longitudinal lines A, B, C, D, E, and transverse lines 5, 6, 7, 8 are the third area; longitudinal lines F, G, H, I, G, K, and transverse lines 5, 6, 7, 8 are the fourth area; there is a temperature and humidity sensor above each area of ​​the heating plate. The heating position of the heating lamp beads and the amount of heat generated are controlled to achieve the process requirements, and the feedback from the arranged temperature and humidity sensors is used to control the heating and heating speed of different positions by the control module to achieve the process requirements of precise control of heating and baking.

[0016] Figure 5 , Figure 6 The second embodiment of the heating plate, the heating plate has a rectangular heating plate body 18, the heating plate body 18 has a heating plate longitudinal edge 21, the heating plate longitudinal edge 21 is placed on the support 14 on both sides of the inner wall of the box, a plurality of heating lamp beads 19 and a plurality of heating tubes 20 spaced apart from each other and parallel to the longitudinal edge of the heating plate are arranged in the heating plate body 18, the arrangement of the heating lamp beads 19 is the same as the structure of the second embodiment, the temperature field change sensed by the temperature and humidity sensor of each heating lamp bead is adjusted by adjusting the current through the control module to adjust the heating intensity of the heating lamp bead, the difference is that a plurality of heating tubes 20 spaced apart from each other and parallel to the longitudinal edge of the heating plate are arranged, the heating intensity of the heating tube is adjusted by the current, a temperature and humidity sensor and a region of heating tubes are electrically connected to the same circuit board of the control module at the same time, the temperature field change sensed by the temperature and humidity sensor of each heating tube is adjusted by adjusting the current through the control module to adjust the heating intensity of the heating tube.

[0017] During baking, the items to be baked are placed in the tray of each baking unit. The temperature and humidity sensor located above the items to be baked senses the temperature field. The heat emitted by the heating lamp beads of the heating plate is transmitted upward through the heat radiation holes of the tray to bake the items to be baked in the tray. As the baking time increases, the temperature and humidity sensor data changes. The temperature and humidity sensor transmits the data to the control module, and changes the heating intensity of the heating tubes and heating lamp beads by adjusting the current size of the heating tubes and heating lamp beads in a region. There is an insulation layer above the temperature and humidity sensor of each baking unit, so that each baking unit has a separate temperature field and will not be affected by the heating plates of other baking units.

[0018] The energy-saving baking oven is not limited to the above structure, and the number of baking units in the box is not limited to three, but can be four, five or more. The heat insulation layer has a cavity, and the wire connected to the temperature and humidity sensor passes through the cavity of the heat insulation layer and is connected to the control module.

[0019] The energy-saving baking oven adopts such a structure. When baking, the items to be baked are placed in the tray of each baking unit. The temperature and humidity sensor located above the items to be baked senses the temperature field. The heating plate bakes the items to be baked through the heat radiation holes of the tray. The heating tube or heating lamp of the heating plate adjusts the current through the control module to adjust the heating intensity of the heating tube or heating lamp bead by the temperature field changes sensed by the temperature and humidity sensor, so as to achieve energy saving. Moreover, when there is no tray in the baking unit, the heating plate is not turned on and cannot generate heat, so as to achieve further energy saving. Advantages of energy-saving baking oven: 1. Intelligent, it can be controlled by program, through sensor feedback, closed loop precise control of heating temperature and time to meet product process requirements, 2. High efficiency and energy saving. The number of trays can be flexibly adjusted to reduce power consumption. According to the different process requirements of product heating, the heat generation of different areas can be controlled to achieve precise heating to reduce unnecessary overheating, improve baking quality, and reduce energy consumption. 3. The temperature field changes inside the baking oven can be observed in real time through the network, which is safe and reliable.
