Description

Technical Field

[0001] This application relates to the field of baking apparatus, and more particularly to a hot air circulating baking apparatus. Background Technology

[0002] Baking equipment is widely used in modern food production and daily life. Baking equipment is generally provided with heat by a heating system (such as electric heating elements, gas burners, etc.), a hot air circulation system to make hot air flow evenly inside the equipment to ensure that the material is heated evenly, an insulation structure to reduce heat loss, and a control system to precisely regulate parameters such as temperature and time.

[0003] Most baking equipment on the market currently uses single-point heat source radiant heating or unidirectional hot air direct blowing. Baking ovens typically rely on top or side wall fans for forced air supply, with hot air blowing directly onto the material surface and then quickly exhausted (see...). Figure 1 The chamber lacks an effective circulation guidance structure. Actual tests show that the vertical temperature difference inside the chamber can reach 30-50℃ (e.g., the top layer reaches 170℃ when the bottom layer is 120℃), causing uneven heating of materials and making food prone to problems such as burnt exterior and undercooked interior, and loss of effective components in medicinal materials due to pyrolysis.

[0004] Regarding the aforementioned technologies, the inventors believe that existing baking devices suffer from uneven heating of materials. Therefore, they propose a hot air circulation baking device to solve the above problems. Utility Model Content

[0005] To address the problem of uneven heating of materials in existing baking devices, this application provides a hot air circulation baking device.

[0006] The hot air circulating baking device provided in this application adopts the following technical solution:

[0007] A hot air circulating baking device includes a mounting base, an oven being mounted on the upper surface of the mounting base, a control panel being mounted on one side of the front face of the oven, a placement cavity being formed inside the oven, a door being hinged to one side of the inner wall of the placement cavity near the front face, a viewing window being fixedly mounted at the middle of one end of the door, a support turntable being rotatably mounted at the middle of the bottom end of the inner wall of the placement cavity, a drive motor being mounted on the middle of the bottom end of the support turntable extending into the mounting base, a support frame being fixedly mounted on the upper surface of the support turntable, a protective top plate being fixedly connected to the middle of the top of the support frame, and a hot air circulation mechanism being provided inside the placement cavity for heating the interior of the placement cavity.

[0008] Preferably, the hot air circulation mechanism includes several fixed plates, which are fixedly installed on both sides of the inner wall of the placement cavity. Several hot air conveying pipes are provided on both sides of the fixed plates. One end of the hot air conveying pipe passes through the top of the baking oven and is installed with a hot air pipe. A vent is provided in the middle of one end of the inner wall of the placement cavity.

[0009] Preferably, a circular groove is formed at the bottom center of the inner wall of the placement cavity, and the bottom of one side of the support turntable is located inside the circular groove, with the support turntable and the inside of the circular groove fitting together.

[0010] Preferably, the volume of the support frame and the protective top plate is smaller than the internal volume of the placement cavity, and both the support frame and the protective top plate are in contact with the placement cavity.

[0011] Preferably, a placement groove is provided at one end of the inner wall of the placement cavity near the front end face, and the box door is located inside the placement groove, with the box door and the placement groove fitting together.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using multiple hot air delivery pipes installed on both sides of the inner wall of the placement cavity, hot air can be blown evenly onto the material inside the placement cavity from multiple directions. This, combined with the ventilation openings, forms an effective hot air circulation. The drive motor rotates the support turntable, which in turn causes the support frame, the protective top plate, and the material placed on it to rotate. The material can be baked by hot air from all directions, further improving the uniformity of heating, reducing temperature differences inside the baking device, making the material heat up more evenly, and improving the baking quality.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a hot air circulating baking apparatus. (Refer to...) Figure 1-3 A hot air circulating baking device includes a mounting base 1, an oven 2 mounted on the upper surface of the mounting base 1, a control panel 3 mounted on one side of the front face of the oven 2, a placement cavity 6 inside the oven 2, a door 4 hinged to one side of the inner wall of the placement cavity 6 near the front face, a placement groove opened at one end of the inner wall of the placement cavity 6 near the front face, the door 4 being located inside the placement groove, the door 4 and the placement groove fitting together, a viewing window 5 fixedly mounted in the middle of one end of the door 4, and a support turntable 7 rotatably mounted in the middle of the bottom end of the inner wall of the placement cavity 6. A circular groove is provided, and the bottom of one side of the support turntable 7 is located inside the circular groove. The support turntable 7 and the circular groove are interlocked. The bottom center of the support turntable 7 extends into the mounting base 1 and a drive motor 8 is installed therein. A support frame 9 is fixedly installed on the upper surface of the support turntable 7. A protective top plate 10 is fixedly connected to the top center of the support frame 9. The volume of the support frame 9 and the protective top plate 10 is smaller than the internal volume of the placement cavity 6. The support frame 9 and the protective top plate 10 are in contact with the placement cavity 6. The placement cavity 6 is also equipped with a hot air circulation mechanism for heating the inside of the placement cavity 6.

[0020] When using this hot air circulating baking device, first open the chamber door 4, place the material to be baked on the support frame 9, then close the chamber door 4. Set the baking temperature, time, and other parameters via the control panel 3, start the drive motor 8 to rotate the support turntable 7, which in turn causes the support frame 9, the protective top plate 10, and the material to rotate. During the baking process, the operator can observe the baking status of the material through the viewing window 5. When the set baking time is reached, the drive motor 8 and the hot air circulation mechanism stop working, the chamber door 4 is opened, and the baked material is removed.

[0021] Reference Figure 2 and Figure 3 The hot air circulation mechanism includes several fixed plates 11, which are fixedly installed on both sides of the inner wall of the placement cavity 6. Several hot air conveying pipes 12 are provided on both sides of the fixed plates 11. One end of the hot air conveying pipe 12 passes through the top of the baking oven 2 and is installed with a hot air pipe. A vent 13 is provided in the middle of one end of the inner wall of the placement cavity 6.

[0022] Hot air is delivered to the hot air delivery pipe 12 through the hot air duct, and the hot air is blown out from the hot air delivery pipe 12 and blown evenly to the material inside the placement cavity 6. The hot air circulates inside the placement cavity 6. During the hot air circulation, some of the hot air is discharged through the vent 13 or participates in the circulation again to maintain the flow of hot air and the uniformity of temperature inside the placement cavity 6.

[0023] The implementation principle of the hot air circulation baking device in this application embodiment is as follows: When using the hot air circulation baking device, first open the oven door 4, place the material to be baked on the support frame 9, and then close the oven door 4. Set the baking temperature, time and other parameters through the control panel 3.

[0024] The drive motor 8 is started, causing the support turntable 7 to rotate. The input terminal of the drive motor 8 is electrically connected to the output terminal of an external power supply, thereby causing the support frame 9, the protective top plate 10, and the material to rotate. Simultaneously, the hot air circulation mechanism starts working. The hot air duct delivers hot air to the hot air delivery pipe 12, from which the hot air is blown evenly onto the material inside the placement cavity 6. The hot air circulates within the placement cavity 6, heating and baking the material. During the hot air circulation process, some of the hot air is discharged through the vent 13 or re-enters the circulation to maintain the flow and temperature uniformity of the hot air within the placement cavity 6.

[0025] During the baking process, the operator can observe the baking status of the material through the viewing window 5. When the set baking time is reached, the drive motor 8 and the hot air circulation mechanism stop working, the chamber door 4 is opened, and the baked material is taken out.
