[0002] In the process of bread making, the raw materials need to be baked. Baking is usually done in an electric oven. The most common electric oven is an infrared electric oven. One or more infrared heaters are placed inside the infrared electric oven. The infrared radiation they emit can directly irradiate the surface of the food. When the infrared radiation irradiates the food, the food absorbs the infrared radiation and converts it into heat energy.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN215993698U is provided with a handle hidden inside, which can be used to safely take out the placement plate after baking, and the handle is convenient and quick to store, and the operation is simple; when electric baking, the air holes at different positions are blocked to ensure that the air entering the interior is appropriate and the water vapor is taken away, while the internal temperature will not be lowered, thereby ensuring the baking effect and convenient adjustment.

[0004] However, the device still has some shortcomings: the single baking capacity of the electric oven is limited, and the infrared lamp in the infrared electric oven heats the food by radiation when in operation, and the temperature of the handle is easily increased in this state. At the same time, the current larger electric ovens have large internal volumes and many tray layers, but it is troublesome and dangerous to take and place the upper tray. Utility Model Content

[0014] Preferably, the articulated rod includes two connecting rods A and connecting rod B that rotate with each other, and the ends of connecting rod A and connecting rod B that are away from each other are respectively rotatably connected to the sides close to the two slides on the corresponding sides. At the same time, limit members are provided on connecting rod A and connecting rod B so that connecting rod A and connecting rod B are not in a straight line when fully extended.

[0015] Preferably, the lifting drive member includes a high temperature resistant linear module.

An observation window 201 is arranged on the door 2, a transparent heat insulation board 3 is embedded in the observation window 201, and a radiation protection board 4 for preventing infrared light from emitting from the observation window 201 is slidably arranged on the door 2. The temperature control assembly is connected to the oven 1 to adjust the temperature in the oven 1. The temperature control assembly comprises a temperature sensor and a controller 5, the temperature sensor is connected to the oven 1, and the detection end of the temperature sensor is located in the oven 1, the temperature sensor is electrically connected to the controller 5, and the controller 5 is electrically connected to each far-infrared lamp 9. The multi-layer slides 7 are all located in the oven 1 and are slidably connected to the inner wall of the oven 1, the slides 7 are slidably connected to the tray 8 for placing bread, and the upper wall of the inner cavity of the oven 1 and each layer of the slides 7 are provided with far-infrared lamps 9. The far-infrared lamp 9 on the slide 7 is located below the tray 8 on the slide 7. Two adjacent slides 7 are connected by a set of independent hinged rods 10. The hinged rod 10 includes two connecting rods A and connecting rod B that rotate with each other, and the ends of connecting rod A and connecting rod B that are away from each other are respectively connected to the sides of the two slides 7 on the corresponding sides. At the same time, limiters are set on connecting rod A and connecting rod B so that connecting rod A and connecting rod B are not in a straight line when fully unfolded. The lifting drive 12 includes a high temperature resistant linear module. Connecting seats 11 are set on both sides of the uppermost slide 7, and the output ends of the linear modules on both sides are respectively connected to the connecting seats 11 on the corresponding sides. The lifting drive 12 drives the uppermost slide 7 to rise and fall, so as to pull up or lower the slide 7 and the tray 8 layer by layer through the hinged rod 10.

[0027] In this embodiment, in the initial state, the uppermost tray 8 is in the lowest position. After the staff opens the door 2, they fill the uppermost tray with bread, then start the linear module to pull up the uppermost slide 7 until the uppermost hinged rod 10 is in the extreme expansion state, and then place bread on the second-layer tray 8, and so on. After each layer of trays 8 is filled with bread, the door 2 is closed, and then the baking program is started. The far-infrared lamp 9 heats and bakes the bread inside the oven 1.
