The temperature inside the oven cavity is controlled by controlling the temperature of the heating element. This method makes it difficult to ensure temperature uniformity in all parts of the cavity, and there are few temperature monitoring points inside the existing cavity, which can easily cause a large deviation between the oven's set temperature and the actual temperature.

[0008] Furthermore, the outer walls of the inner cavity are all lined with insulating cotton.

[0009] Furthermore, the outer wall of the left air cavity is provided with a perforation, and the hot air volume adjustment mechanism includes a rotating shaft passing through the perforation.

[0012] Furthermore, a control panel for controlling the motor is provided on one side of the outer casing, and the temperature sensor is electrically connected to the control panel.

[0013] Furthermore, the ventilation holes on the inner wall of the left air cavity and the ventilation holes on the inner wall of the right air cavity are arranged in an array.

[0014] Compared with the prior art, the ventilation holes on the inner wall of the left air cavity of this utility model are arranged in an array, and temperature sensors are set at the four corners of the inner cavity.

[0022] See Figure 1 , Figure 3 and Figure 4 In one embodiment of this utility model, a temperature-controlled preheating oven includes an outer box 1, an inner cavity 2 disposed inside the outer box 1 for placing baking materials, and a drying module 4. The inner cavity 2 includes a left air cavity 21, an inner cavity 22, and a right air cavity 23; The drying hot air generated by the drying module dries the material in the inner cavity through the left air cavity 21, the inner cavity 22, and the right air cavity 23; A hot air volume adjustment mechanism 3 is provided between the left air cavity 21 and the inner cavity 22. In practical applications, temperature regulation is achieved by controlling the temperature of the heating tube 43 and adjusting the hot air volume entering the inner cavity 22 using the hot air volume adjustment mechanism 3.

[0023] See Figure 3 In one embodiment of the present invention, the drying module 4 includes a hot air heating chamber 41, a fan 42, and a heating tube 43 disposed in the hot air heating chamber 41; the fan 42 blows air into the hot air heating chamber, the left air outlet 44 of the hot air heating chamber 41 is connected to the left side air chamber 21, and the right air outlet 45 of the hot air heating chamber 41 is connected to the right side air chamber 23.

[0024] See Figure 3 In the above embodiment, the air outlet of the fan 42 faces to the left, so that the air blown out from the air outlet enters the left air cavity 21 through the left air outlet, then enters the inner cavity 22, and then enters the right air cavity 23 and returns to the hot air heating cavity 41 through the right air outlet 45.

[0025] In one embodiment of this utility model, the fan 42 is model KL370.

[0026] See Figure 2 In one embodiment of the present invention, the inner cavity 2 has an opening 24 for taking out and putting in materials.

[0027] See Figure 1 and Figure 2 In the above embodiment, the outer casing 1 is provided with a front door panel 5 that opens and closes on one side and is used to close the opening 24.

[0028] In the above embodiment, the front door panel 5 is connected to the outer casing 1 by a hinge to realize the opening and closing of the front door panel.

[0029] See Figure 3 or Figure 4 In one embodiment of this utility model, the outer wall of the inner cavity 2 is provided with heat insulation cotton 6; this reduces heat transfer to the outside, prevents the outer box from overheating and causing burns, and at the same time maintains the stability of the oven temperature, reduces energy loss, and improves heating efficiency.

[0030] See Figure 3 and Figure 4 In one embodiment of the present invention, the outer wall of the left air cavity 21 is provided with a perforation, and the hot air size adjustment mechanism 3 includes a rotating shaft 31 passing through the perforation. One end of the rotating shaft 31 is provided with an air volume adjustment plate 32 for adjusting the size of the ventilation hole 25 on the inner wall of the left air cavity, and the other end of the rotating shaft 31 is driven by a motor 33.

[0031] In one embodiment of this utility model, the motor 33 is model number TST20-28P.

[0032] See Figure 2 or Figure 3 In the above embodiment, the inner cavity 2 is also provided with a temperature sensor 7 for monitoring the temperature of the inner cavity.

[0033] See Figure 2 Alternatively, in one embodiment of this utility model, the number of temperature sensors 7 is four, which are respectively set at the four corners of the inner cavity 22; to monitor the temperature around the inner cavity 22, when there is a deviation between the temperature sensor and the set temperature, the hot air volume adjustment mechanism 3 adjusts the hot air volume entering the inner cavity 22, thereby adjusting the temperature of the inner cavity 22 and further ensuring the temperature uniformity of various positions inside the cavity.

[0034] See Figure 1 In one embodiment of this utility model, a control panel 8 for controlling the motor 33 is provided on one side of the outer casing 1. The temperature sensor 7 is electrically connected to the control panel 8 (a conventional connection, which will not be described in detail; this utility model only protects the structure). The temperature sensor 7 transmits the temperature to the control panel 8, and the control panel 8 controls the rotation of the motor 33.

[0035] See Figure 2 and Figure 5 In one embodiment of this utility model, the ventilation holes 25 on the inner wall of the left air cavity and the ventilation holes 26 on the inner wall of the right air cavity are arranged in an array; this further ensures the temperature uniformity of various positions inside the cavity.

[0036] In practical applications, the air blown out by the fan enters the left air cavity through the left air outlet, and then enters the inner cavity through the ventilation holes on the inner wall of the left air cavity. After that, it enters the right air cavity through the ventilation holes on the inner wall of the right air cavity, and then returns to the hot air heating cavity through the right air outlet. When there is a deviation between the temperature sensor and the set temperature, the motor drives the rotating shaft, which in turn drives the air volume adjustment plate to rotate, thereby enlarging or reducing the ventilation holes on the inner wall of the left air cavity, adjusting the amount of hot air entering the inner cavity, and thus achieving temperature regulation.
