Description

Technical Field

[0001] This utility model relates to the field of sheet metal structures and power facility supporting equipment, and in particular to an intelligent self-cleaning top-ventilated oven structure. Background Technology

[0002] In the production of precision electronic and optoelectronic products such as IT window glass, solar crystalline silicon cells, FPC, and PCB circuit boards, baking and drying are key processes. Traditional drying equipment has problems such as uneven temperature zones and poor adaptability. In particular, precision components such as semiconductor wafers and LCD displays have strict requirements for the cleanliness and temperature uniformity of the baking environment. Therefore, an intelligent self-cleaning top-ventilated oven structure has emerged.

[0003] The intelligent self-cleaning top-ventilated oven integrates a high-efficiency power system with the baking cavity. It achieves uniform heating by driving hot air circulation through a motor. Its compact structure is suitable for automated production line connections. In scenarios such as FPC flexible circuit board curing and touch panel ink drying, this design can meet semiconductor-grade cleanliness standards and optimize energy consumption through motor technology, filling the technological gap in precision process baking equipment.

[0004] In the production of precision components, while intelligent self-cleaning top-ventilated ovens optimize drying efficiency, they lack sufficient intelligence. When dealing with different materials such as glass substrates, FPC circuit boards, and semiconductor wafers, manual adjustment of baking temperature, duration, and hot air circulation parameters is required. For example, glass drying needs to consider softening point and prevent deformation, while PCB ink curing is sensitive to temperature gradient. Manual adjustment is time-consuming and prone to fluctuations in yield. This manual operation mode is difficult to adapt to the intelligent and flexible requirements of modern manufacturing when switching between multiple product categories or large-scale production. Therefore, an intelligent self-cleaning top-ventilated oven structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent self-cleaning top-ventilated oven structure, which aims to improve the problem of uneven heating of products and the problem of small impurities being mixed into the high-temperature hot air and circulating with the hot air driven by the motor in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart self-cleaning top-ventilated oven structure includes an outer oven cover assembly, an inner oven liner assembly, a heating element assembly, a return air duct, and inlet / outlet door structures. The top of the outer oven cover assembly has two fixed air outlets and two fixed air inlets. Heating element assemblies are fixedly connected to both sides of the outer oven cover assembly. Movable door assemblies are rotatably connected to both sides of the outer oven cover assembly, as are movable door assemblies. Return air ducts are fixedly connected to both sides of the outer oven cover assembly. The inner oven liner assembly is fixedly connected to the inner wall of the outer oven cover assembly. Two inlets are opened on the inner wall of the outer oven cover assembly, and sliding door assemblies are slidably connected to the inner walls of the inlets. A high-efficiency filter is fixedly connected to the inner wall of the outer oven cover assembly.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the furnace cover assembly has two discharge ports, an air inlet chamber is fixedly connected to the inner wall of the furnace cover assembly, a material loading chamber is fixedly connected to the inner wall of the furnace cover assembly, and two axial flow fan assemblies are fixedly connected to the top of the furnace cover assembly.

[0010] As a further description of the above technical solution:

[0011] One side of the air inlet cavity is in contact with one side of the high-efficiency filter, and one side of the movable door assembly one is in contact with one side of the movable door assembly two.

[0012] As a further description of the above technical solution:

[0013] The heating element assembly has an L-shaped cross-section, and the air outlet and the air inlet face the same direction.

[0014] As a further description of the above technical solution:

[0015] The cross-sectional shape of the air outlet is L-shaped, and the shape of the air inlet is L-shaped.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the sliding door assembly allows materials to enter the loading chamber through the feed inlet and be heated. The flowing air inside the furnace cover assembly returns to the heating tube assembly via the return air pipe. If the internal air volume is insufficient, the air inlet will automatically compensate for the air intake, ensuring that the airflow inside the furnace cover assembly is always stable and sufficient. The heated gas is transported to the air inlet chamber by the axial flow fan assembly, and excess gas is discharged through the air outlet. When the heated gas enters the loading chamber through the high-efficiency filter, fine impurities such as dust and particles are completely filtered out. This design not only avoids the wear and tear on the equipment caused by impurities and greatly extends the service life of the oven, but also achieves intelligent self-cleaning of the equipment through continuous filtration, reducing the need for manual maintenance.

[0018] 2. In this utility model, after the material is heated, it flows out through the discharge port. The sliding door assembly guides the material in and out of the outer cover assembly and ensures the oven's airtightness when closed, reducing heat loss. The inner liner assembly can effectively lock in the temperature and achieve good heat preservation. The movable door assembly one allows for easy observation of the internal baking status, enabling progress monitoring without opening the equipment. The axial flow fan assembly can stir the gas inside the chamber and adjust the airflow speed, making the heating more uniform. The movable door assembly two provides a convenient replacement channel for the high-efficiency filter, ensuring stable filtration effect. These designs not only extend the oven's service life but also improve operating efficiency and self-cleaning ability. Attached Figure Description

[0024] 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.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of an intelligent self-cleaning top-ventilated oven structure, including an outer casing assembly 6. The outer casing assembly 6 serves as the main outer shell of the oven, providing installation space and protection for internal components, ensuring internal structural stability during oven operation, and preventing excessive heat loss. Two air outlets 7 are fixedly connected to the top of the outer casing assembly 6. These outlets 7 are used to expel excess gas, volatile inks, and other impurities generated during heating within the oven, maintaining gas pressure balance and ensuring smooth air circulation. Two air inlets 1 are fixedly connected to the top of the outer casing assembly 6, supplementing air intake when there is insufficient air inside the oven. To ensure sufficient airflow inside the oven cover assembly 6 and maintain stable heating, a heating element assembly 2 is fixedly connected to one side of the oven cover assembly 6. The heating element assembly 2 is the core heat source of the oven, heating the air to provide the necessary heat for baking the materials. The motor is located on top of the heating element assembly 2. A movable door assembly 2 4 is rotatably connected to one side of the oven cover assembly 6. The movable door assembly 2 4 can be rotatably opened. A movable door assembly 3 is rotatably connected to one side of the oven cover assembly 6. The movable door assembly 3 can be rotatably opened, allowing the operator to observe the baking status of the materials inside the oven and keep track of the baking progress in a timely manner.

[0026] A return air duct 5 is fixedly connected to one side of the oven hood assembly 6. As a core component of the oven's internal air circulation system, the return air duct 5's core function is to efficiently guide the hot air from the oven cavity back to the heating element assembly 2. This circulation path creates a closed air circulation loop. This design has two key benefits: firstly, it avoids energy waste caused by direct hot air dissipation, allowing heat to be repeatedly utilized in the circulation, significantly improving the performance of the heating element assembly 2. The oven generates heat efficiently, reducing energy consumption. On the other hand, the circulating hot air breaks up local temperature differences within the oven, allowing heat to penetrate evenly to every corner, effectively avoiding uneven baking of raw materials caused by uneven temperature distribution in traditional ovens, ensuring stable baking results. The inner wall of the oven cover assembly 6 is fixedly connected to the inner liner assembly 9, which effectively reduces heat loss and provides insulation, maintaining a stable temperature environment during oven operation and improving baking performance. The inner wall of the oven cover assembly 6 has two feed inlets 10, which are channels for materials to enter the oven. A sliding door assembly 11 is slidably connected to the inner wall of the feed inlets 10. The door assembly 11 can slide on the inner wall of the feed inlet 10 to control the material in and out. When closed, it can effectively ensure the oven's airtightness, preventing heat leakage and the entry of external debris. The inner wall of the oven cover assembly 6 is fixedly connected to a high-efficiency filter 15. The high-efficiency filter 15 is used to filter impurities in the gas entering the loading chamber 13, ensuring a clean baking environment, avoiding material contamination, and greatly reducing the probability of the entire oven being affected by fine particles. Thanks to the presence of the blower nozzle, the dust removal effect of the entire oven is improved from the side. The inner wall of the oven cover assembly 6 has two discharge ports 12. The discharge ports 12 are the outlets after the material is baked, making it convenient to remove the material from the oven.

[0027] An air inlet chamber 14 is fixedly connected to the inner wall of the oven cover assembly 6, and a material loading chamber 13 is fixedly connected to the inner wall of the oven cover assembly 6. The material loading chamber 13 is used to place the material to be baked and is the working area for the material to be heated and baked. Two axial flow fan assemblies 8 are fixedly connected to the top of the oven cover assembly 6. The axial flow fan assemblies 8 deliver the heated gas to the air inlet chamber 14, accelerate the gas flow, promote heat exchange in the oven, and improve the baking efficiency. Thanks to the presence of the perforated plate, and the structure of the perforated plate is uneven, the wind speed is more stable. Thanks to the presence of the sheet metal structure, the airflow can be guided in an orderly manner. Its flat surface and regular structure can decompose strong airflow, buffer wind speed, avoid local airflow concentration, and allow the wind to diffuse naturally in the flow, ultimately achieving a more uniform effect of the wind blowing down and improving the stability of the airflow.

[0028] One side of the air inlet cavity 14 is in contact with one side of the high-efficiency filter 15, ensuring that the heated gas can pass smoothly through the high-efficiency filter 15 before entering the loading cavity 13, ensuring gas cleanliness. One side of the movable door assembly 3 is in contact with one side of the movable door assembly 4. When closed, the two fit tightly together, enhancing the oven's sealing and reducing heat loss and external interference. The heating tube assembly 2 has an L-shaped cross-section, which expands the heating area, making the air heated more evenly and improving the heating effect. The air outlet 7 and the air inlet 1 have random opening orientations, which facilitates stabilizing the internal air pressure and airflow, forming a good air circulation path. The air outlet 7 has an L-shaped cross-section, and the air inlet 1 has an L-shaped shape. This shape design helps control the gas flow rate and direction, optimizing the air circulation system inside the oven.

[0029] Working Principle: The sliding door assembly 11 allows materials to enter the loading chamber 13 through the feed inlet 10 for heating. Air flowing inside the furnace hood assembly 6 returns to the heating element assembly 2 via the return air duct 5. When the air flow inside the furnace hood assembly 6 is insufficient, the air inlet 1 compensates for the insufficient airflow, ensuring a stable and sufficient flow of gas inside the furnace hood assembly 6. The heated gas is transported to the air inlet chamber 14 via the axial flow fan assembly 8, while excess gas is discharged through the air outlet 7. The heated gas then enters the loading chamber 13 through the high-efficiency filter 15. Thanks to the high-efficiency filter 15, fine impurities such as dust and particles in the gas are isolated and filtered, significantly extending the lifespan of the entire oven and enabling intelligent automatic operation of the entire oven. The cleaning effect is excellent, and the material can flow out through the discharge port 12 after heating. Thanks to the existence of the sliding door assembly 11, the material can enter and exit the interior of the oven cover assembly 6, and the door can ensure the sealing of the oven when closed. Thanks to the existence of the oven inner liner assembly 9, the oven can achieve a heat preservation effect. Thanks to the existence of the movable door assembly 1 3, the internal condition of the oven can be observed. Thanks to the existence of the axial flow fan assembly 8, the gas inside the oven can be stirred and the gas flow speed inside the box can be controlled. Thanks to the existence of the movable door assembly 2 4, the high-efficiency filter 15 can enter and exit the inner wall of the oven cover assembly 6 for easy replacement. As a result, the service life of the entire oven is greatly extended and the operating efficiency is significantly improved, while the self-cleaning effect of the entire oven is greatly improved.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
