Description

Technical Field

[0001] This utility model relates to the field of baking oven technology, and more specifically, to a baking oven with adjustable wind speed and air volume. Background Technology

[0002] An adjustable speed and airflow oven is a device that optimizes drying / baking results by controlling airflow parameters. It is mainly used in: food industry (drying bread and meat), electronics manufacturing (PCB board curing), laboratories (material drying), and home baking (precise temperature and airflow control).

[0003] Conventional oven axial flow fans have relatively small air pressure and air volume. For certain materials that need to be baked by uniform high-temperature air in a short time, these axial flow fans obviously cannot meet the requirements. At the same time, the hot air flow channels in the oven are not easy to clean, making it very time-consuming and laborious for workers to clean and maintain the oven. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] To address the issue of relatively low air pressure and air volume in oven axial flow fans, this solution provides Example 1: Please see Figures 1-5 This utility model discloses an adjustable baking oven with adjustable wind speed and air volume, comprising a box body 1, with a door panel 2 hinged to the front of the box body 1. Two partitions 3 are fixedly connected to the inner wall of the box body 1, with the front of each partition 3 contacting the door panel 2. Air vents 4 are fixedly connected to the top of each partition 3, and the outer sides of each air vent 4 are fixedly connected to the inner wall of the box body 1. A centrifugal circulating fan 5 is installed on the inner top wall of the box body 1, with its top extending through and above the box body 1. Air outlets are located on the left and right sides of the bottom of the centrifugal circulating fan 5, and its bottom is an air inlet. The inner walls of the two air outlets of the centrifugal circulating fan 5 are fixedly connected to the two air vents 4 respectively. A mounting bracket 6 is fixedly connected to the inner bottom wall of the box body 1, with two sets of equally spaced support bars 7 fixedly connected to the inner side of the mounting bracket 6. A storage frame 8 is provided between each pair of adjacent support bars 7, with the bottom of the storage frame 8 connected to the two support bars respectively. 7. A sliding connection is provided. Two storage nets 10 are fixedly connected to the inner side of the storage frame 8. Air outlet slots 11 are arranged at equal intervals on both partitions 3. Air volume adjustment mechanisms 12 are provided on both partitions 3. Two sets of electric heating tubes 13 are installed on the top of the box 1. The heating parts of the two sets of electric heating tubes 13 pass through the box 1 and are respectively inserted into the two air outlet hoods 4. The heating parts of the two sets of electric heating tubes 13 are located inside the two air outlet hoods 4. The air volume adjustment mechanism 12 includes an electric push rod 121. The fixed end of the electric push rod 121 is fixedly connected to the inner wall of the box 1. The telescopic end of the electric push rod 121 is fixedly connected to a lifting plate 122. The lifting plate 122 is provided with through slots 123 arranged at equal intervals. A PLC 9 is installed on the right side of the box 1. The PLC 9 is used to control the speed of the centrifugal circulating fan 5.

[0016] In this invention, when in use, the items to be baked are placed on top of the storage net 10 on the storage frame 8. When starting work, the electric heating tube 13 and the centrifugal circulating fan 5 are turned on first. The centrifugal circulating fan 5 will draw the air out of the box 1 and input it into the two exhaust hoods 4 respectively. The electric heating tube 13 will heat the air in the exhaust hoods 4. Then the heated air will be input into the air duct formed by the partition 3, the inner wall of the box 1, the door panel 2 and the exhaust hoods 4. The hot air gathers in the air duct and will be discharged into the box 1 through the exhaust slot 11 and the through slot 123 in sequence. The hot air will heat and bake the items. The air will then be drawn out again by the centrifugal circulating fan 5 and sent into the two exhaust hoods 4 for heating, realizing the circulation of air and thus baking the items.

[0017] The baking oven uses a centrifugal circulating fan 5, which is a high-volume centrifugal fan designed with air outlets on both sides and return air in the middle. This allows it to be installed on the top of the box body 1, ensuring the basic requirements of air intake in the middle and air outlet on both sides. It has a large air volume and fast wind speed.

[0018] During use, the lifting plate 122 can be raised and lowered by activating the electric push rod 121. Hot air needs to be discharged from the air outlet 11 and the through channel 123. During the raising and lowering process, the lifting plate 122 will cause the air outlet 11 and the through channel 123 to be misaligned. At this time, the size of the hot air outlet will change, thereby realizing the adjustment of the air volume. Workers can adjust the air volume according to the material conditions.

[0019] During use, the speed of the centrifugal circulating fan 5 can be adjusted via PLC9, thereby regulating the airflow speed of the baking oven.

[0020] To facilitate cleaning and maintenance of the air duct, this solution provides Example 2: Please see Figure 4 and 5 The box 1 has two hinged baffles 14 on the left and right sides inside, and the front of the two baffles 14 is in contact with the door panel 2. The two partitions 3 have threaded locking rods 15 on their opposite sides, and the opposite ends of the two locking rods 15 are respectively inserted into the two baffles 14 and slidably connected to them.

[0021] In this utility model, during use, the baffle 14 can replace the door panel 2 and the partition 3, the inner wall of the box 1 and the air vent 4 to form an air duct. During daily use, dirt will remain in the air duct. When the air duct needs to be cleaned, the worker first opens the door panel 2, then rotates the locking rod 15. The locking rod 15 will be pulled out from the baffle 14, and the baffle 14 can be rotated to the outside of the box 1. After the baffle 14 is rotated, the air duct will be exposed. Then the air duct and the inner wall of the air vent 4 can be cleaned. The process is very convenient and quick, improving the practicality of the device.

[0022] Please see Figure 3 The bottom of the storage frame 8 is rotatably connected to four rollers 16, and the outer sides of the four rollers 16 are in contact with two support bars 7 respectively.

[0023] In this invention, the roller 16 reduces the friction between the storage frame 8 and the support bar 7, making it easier for workers to pull out the storage frame 8 and replace items, thus improving the practicality of the device.

[0024] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
