Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of baking, in particular to a dustless clean baking oven. BACKGROUND

[0002] The dustless clean baking oven is a device for manufacturing high-quality and low-pollution products. Its principle is to bake materials in a high-temperature environment, which can effectively reduce dust emission and prevent materials from deteriorating in the oven. In the past, when producing certain products, they had to be baked at low temperatures, resulting in a large amount of dust. Through the dustless clean baking oven, dust pollution can be effectively reduced to ensure the quality and cleanliness of the products.

[0003] However, the filter cartridge detachable structure of the existing dustless clean baking oven usually only considers the convenience of installation, such as using an elastic clamping piece type filter cartridge structure. Although it is quick to install and can be completed by inserting the filter cartridge without additional operation, the cost is relatively low. However, the clamping force of the elastic clamping piece may weaken over time, especially when subjected to strong airflow impact or vibration, the filter cartridge is prone to looseness, and its filtering effect cannot be guaranteed. If the elasticity of the clamping piece is too large or the installation is not proper, it may scratch or damage the inner wall of the ventilation pipe, which will increase the difficulty and frequency of equipment maintenance and affect work efficiency.

[0004] Therefore, we designed a dustless clean baking oven to solve the above problems. CONTENT OF THE UTILITY MODEL

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a dust-free clean baking oven, including a casing 1, an opening on the front side of the casing 1, and a door 2 rotatably connected to one side of the opening, an air inlet 5 fixedly connected to one side of the casing 1, an air inlet pipe 6 fixedly connected to one end of the air inlet 5, a main ventilation pipe 3 fixedly connected to the top of the casing 1, a side ventilation pipe 21 fixedly connected to the side wall of the main ventilation pipe 3, and filter components provided on both the main ventilation pipe 3 and the side ventilation pipe 21. The filter components include a filter element 20 installed inside the main ventilation pipe 3, a fixing sleeve 18 covering the filter element 20, a fixing block 19 integrally formed on the fixing sleeve 18, and a slot 17 opened on the inner side of the main ventilation pipe 3.

[0023] In practice, the door 2 and air inlet 5 are opened, allowing outside air to enter the casing 1 through the air inlet duct 6 for baking. As the hot air rises, it enters the main ventilation duct 3, which contains a removable filter element 20. This filter element 20 finely filters the air, removing smaller particles and contaminants to prevent contamination of the working environment. The filter element 20 is installed on the fixing sleeve 18, which is then inserted into the main ventilation duct 3. The fixing block 19 is inserted into the corresponding slot 17 to secure the filter element 20. When needed, the fixing sleeve 18 can be slid to remove the filter element 20 for easy cleaning and replacement.

[0024] See Figures 1-5 As shown, control components are installed on both the main ventilation pipe 3 and the side ventilation pipe 21. Each control component includes a valve plate 27 installed inside the main ventilation pipe 3. Symmetrical pin holes are formed on the inner wall of the main ventilation pipe 3, and a valve stem 22 is installed between these holes. Pins 23 are fitted onto both ends of the valve stem 22, providing stable fixation and allowing for more precise control of the valve plate 27's rotation angle, while also preventing axial movement of the valve stem 22 during rotation. The valve stem 22 is fixedly connected to the valve plate 27, and a handle 25 is connected to one end of the valve stem 22. A self-locking nut 24 is threaded between the valve stem 22 and the handle 25 to prevent the handle 25 from loosening and to ensure the stability of the control components.

[0025] See Figure 6 The side ventilation pipe 21 is threaded at the end opposite to the main ventilation pipe 3. One end of the side ventilation pipe 21 is provided with a limiting cap 26 that mates with the thread. Small holes are evenly distributed on the end face of the limiting cap 26 to ensure airflow.

[0026] See Figures 1-3 The top of the chassis 1 has a through hole 14, and a mounting tube 15 is fitted inside the through hole 14. A suction fan 16 is fixedly connected inside the mounting tube 15, which allows hot air to flow rapidly inside the chassis 1, which helps to ensure a uniform temperature distribution inside the chassis 1.

[0027] See Figures 1-2 The casing 1 contains multiple heating elements 10, and rollers 4 are fixedly installed at the four corners of the bottom outer wall of the casing 1. An insulation layer 9 is fixedly connected to the inner wall of the casing 1. The insulation layer 9 reduces heat loss to the outside of the casing 1, improving energy efficiency. Metal clamps are fitted around the heating elements 10, securing them to the inner wall of the insulation layer 9 to prevent them from shaking or falling off during operation, thus ensuring stable baking results. A motor 7 is fixedly connected to the outside of one side of the insulation layer 9. The output shaft of the motor 7 passes through the insulation layer 9 and is fixedly connected to a fan 8. The output shaft of the motor 7 is fixedly connected to the rotating shaft of the fan 8.

[0028] See Figures 1-2A protective mesh cover 11 is fixedly connected to the inner top wall of the insulation layer 9. The surface of the protective mesh cover 11 is provided with heat dissipation holes. A bracket 12 is fixedly connected to both sides of the inner wall of the protective mesh cover 11. A baking tray 13 is installed between the brackets 12. Rollers 4 are fixedly installed at the four corners of the bottom outer wall of the chassis 1.

[0029] Working Principle: During use, open the door 2 and air inlet 5 to allow outside air to enter the casing 1 through the air inlet duct 6. Adjust the position of the baking tray 13 according to its size, place the items to be baked on the baking tray 13, and after turning on the power, the resistance wire inside the heating element 10 heats up rapidly, allowing baking to begin. The suction fan 16 draws in internal air and dust into the main ventilation duct 3. Insert the fixing block 19 into the corresponding slot 17 to secure the filter element 20, which then performs fine air filtration. The limiting cap 26 can be tightened at this time to prevent the filter element 20 from accidentally coming out. When needed, slide the fixing sleeve 18 to pull out the filter element 20 for easy cleaning and replacement.

[0030] The operator turns handle 25, which in turn rotates the valve stem 22 connected to it, causing the valve plate 27 to rotate as well. When the valve plate 27 rotates to a certain angle, it completely blocks the airflow passage in the main ventilation pipe 3, thus closing the main ventilation pipe 3. At this time, the airflow will enter the side ventilation pipe 21, ensuring that the oven can still maintain a certain level of ventilation during the filter replacement process.

[0031] The airflow volume and direction can be adjusted by moving the blades of the air inlet 5. The blower fan 8 blows heated and filtered air into the oven, causing the hot air to circulate rapidly within the oven. This helps ensure a uniform temperature distribution within the oven, preventing localized overheating or uneven temperature distribution, thereby improving the quality and effect of baking. The suction fan 16 extracts air from the oven, working in conjunction with the blower fan 8 to create air circulation. This circulation accelerates heat transfer, allowing items to reach the required baking temperature more quickly and shortening baking time. The casters 4 facilitate the movement and layout adjustment of the equipment.
