Description

Technical Field

[0001] This utility model relates to the technical field of blower-air constant temperature drying ovens, specifically a blower-air constant temperature drying oven. Background Technology

[0002] The forced-air humidity drying oven is a multifunctional device that combines constant temperature, constant humidity, and forced-air circulation technology. It is widely used in scientific research, industry, and daily life. Precise temperature control is achieved through electric heating elements and an intelligent temperature control system, resulting in minimal temperature fluctuations and ensuring the stability of the experimental or production environment. An internal fan drives air circulation, ensuring uniform temperature and humidity distribution within the oven and preventing localized overheating or uneven drying.

[0003] A search reveals a Chinese patent for an electrically heated, blower-driven, constant-temperature drying oven, publication number CN 213955823 U. The oven includes a body with an inner shell at its inner end. A support strip is provided on the inner surface of the inner shell, and a convex ring frame is supported on the surface of the support strip. A mesh is fixed to the inner surface of the convex ring frame, and a scraper is placed on the inner surface of the convex ring frame. A toothed rack is provided at the lower end of the scraper. Electric heating wires and a fan are provided on both sides of the upper end of the oven body. A strip-shaped air vent is provided on the inner surface of the inner shell. This inner-outer-layer design, with the strip-shaped air vent on the inner shell surface, facilitates heat conduction from both sides, ensuring uniform heat distribution and good insulation. Simultaneously, the scraper inside the convex ring frame can scrape and turn the material, facilitating the drying process.

[0004] The narrow spacing between the support plates in existing vertical forced-air drying ovens (because the support frame is directly inserted between the two support plates) restricts cleaning operations when cleaning the interlayer area between the two support plates, easily leading to incomplete cleaning. Furthermore, disassembling the support plates for thorough cleaning is not only cumbersome but also time-consuming and labor-intensive. Therefore, a forced-air constant-temperature drying oven is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a forced-air constant-temperature drying oven to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a forced-air constant temperature drying oven, comprising:

[0007] A vertical forced-air drying oven, wherein a support plate is installed inside the vertical forced-air drying oven, and a support frame is inserted between the support plates;

[0008] The convenient component includes a fixed plate, a rotating shaft, a second opening, and a support rod. The fixed plate is welded to both sides inside the vertical blower drying oven. The rotating shaft is welded to the side of the support plate inside the vertical blower drying oven, and its two ends are rotatably connected to the side of the fixed plate. The second opening is opened on the fixed plate where the pin is located, and the support rod is inserted into the second opening.

[0009] Furthermore, the convenient component also includes a first opening and a pin. The first opening is formed at both ends of the fixing plate. One end of the rotating shaft is inserted into the first opening of one of the fixing plates, and the pin is fixed at the other end of the rotating shaft and inserted into the first opening of the other fixing plate.

[0010] Furthermore, the convenient component also includes a limiting block and a connecting plate. The limiting block is fixed to one end of the support rod, and the connecting plate is fixed to two limiting blocks on the side of the same fixing plate.

[0011] Furthermore, the end of the support rod away from the connecting plate is located below the support plate inside the vertical blower drying oven.

[0012] Furthermore, the limiting block and the connecting plate are located on the side of the pin, and there is a gap between them.

[0013] Furthermore, it also includes a limiting component, which includes a third opening and a T-shaped insert. The third opening is opened at one end of the support plate inside the vertical blower drying oven, and the T-shaped insert is inserted into the third opening of the two support plates and is locked onto the support frame inside the vertical blower drying oven.

[0014] Furthermore, the limiting component also includes a limiting groove, which is opened at the lower end of the T-shaped insert and is engaged with both sides of one of the steel wires of the internal support frame of the vertical blower drying oven.

[0015] Furthermore, the limiting component also includes a pull plate, which is fixed to the upper end of the T-shaped insert.

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

[0017] This invention, through its convenient components, allows for easy cleaning of the box's interior. By pulling out the support frame and connecting plate, the support rods on the two limit blocks move out of the second opening. At this point, one end of the support plate falls under its own weight, causing the rotating shaft and pin to rotate around the first opening on the fixed plate, thus cleaning the box. After cleaning the inner wall of the box at the upper part of the support plate, one hand pushes the upper support plate, causing it to flip upwards towards the end away from the rotating shaft, cleaning the inner wall between the two support plates. Then, the lower support plate is pushed, also flipping upwards to clean the lower inner wall. This design allows for cleaning of the box's inner wall without disassembling the support plates, reducing cleaning complexity and improving efficiency. Attached Figure Description

[0026] 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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a forced-air constant temperature drying oven, comprising:

[0029] Vertical forced-air drying oven 10, with support plates installed inside and support frames inserted between the support plates;

[0030] Vertical blower drying oven 10, model DHG-50A, is the main unit. It has a built-in multi-layer support plate for mounting the support frame, which is used to place the items to be dried.

[0031] The convenient component includes a fixed plate 20, a rotating shaft 22, a second opening 24, and a support rod 25. The fixed plate 20 is welded to both sides inside the vertical blower drying oven 10. The rotating shaft 22 is welded to the side of the support plate inside the vertical blower drying oven 10, and its two ends are rotatably connected to the side of the fixed plate 20. The second opening 24 is opened on the fixed plate 20 where the pin 23 is located. The support rod 25 is inserted into the second opening 24.

[0032] The convenient component also includes a first opening 21 and a pin 23. The first opening 21 is opened at both ends of the fixing plate 20. One end of the rotating shaft 22 is inserted into the first opening 21 of one of the fixing plates 20, and the pin 23 is fixed at the other end of the rotating shaft 22 and inserted into the first opening 21 of the other fixing plate 20.

[0033] The convenient components also include a limiting block 26 and a connecting plate 27. The limiting block 26 is fixed to one end of the support rod 25, and the connecting plate 27 is fixed to the two limiting blocks 26 on the side of the same fixing plate 20.

[0034] The end of the support rod 25 away from the connecting plate 27 is located below the support plate inside the vertical blower drying oven 10;

[0035] The limiting block 26 and the connecting plate 27 are located on the side of the pin 23, and there is a gap between them and the pin 23;

[0036] The fixed plate 20 is welded to both sides of the box body and serves as the base for other moving parts. The rotating shaft 22 is installed on the side of the support plate and is hinged to the fixed plate 20 through the first opening 21 at both ends to form a rotation fulcrum. The pin 23 is fixed to the end of the rotating shaft 22 and inserted into the first opening 21 of the fixed plate 20 on the other side to lock the position of the rotating shaft 22. The second opening 24 is used to connect the support rod 25, which is used to support the support plate. The limiting block 26 plays a limiting role. The connecting plate 27 facilitates the unified movement of the two limiting blocks 26.

[0037] Working principle:

[0038] When it is necessary to clean the inside of the box, pull out the support frame and pull the connecting plate 27. This will cause the support rods 25 on the two limit blocks 26 to move out of the second opening 24. At this time, one end of the support plate will fall due to its own weight, causing the rotating shaft 22 and the pin 23 to rotate around the first opening 21 on the fixed plate 20 to clean the box. After cleaning the inner wall of the box at the upper part of the support plate, push the upper support plate with one hand to make it flip upwards towards the end away from the rotating shaft 22 to clean the inner wall of the box between the two support plates. Then push the lower support plate to make it flip upwards as well to clean the inner wall of the lower part of the box.

[0039] This step allows for cleaning of the inner wall of the box without disassembling the support plate, reducing the complexity of cleaning and improving cleaning efficiency.

[0040] Please see Figure 2 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The limiting component includes a third opening 30 and a T-shaped insert 31. The third opening 30 is opened at one end of the support plate inside the vertical blower drying oven 10. The T-shaped insert 31 is inserted into the third opening 30 of the two support plates and is snapped onto the internal support frame of the vertical blower drying oven 10.

[0042] The limiting component also includes a limiting groove 32, which is opened at the lower end of the T-shaped insert 31 and is engaged with both sides of one of the steel wires of the internal support frame of the vertical blower drying oven 10.

[0043] The limiting component also includes a pull plate 33, which is fixed to the upper end of the T-shaped insert 31;

[0044] The third opening 30 facilitates the insertion of the T-shaped insert 31, which serves as a support, while the limiting groove 32 provides a limiting position, and the pull plate 33 facilitates hand movement of the T-shaped insert 31.

[0045] Working principle:

[0046] After cleaning the inside of the vertical blower drying oven 10, hold the two support plates with one hand and the connecting plate 27 with the other, insert the support rod 25 into the second opening 24 until the limiting block 26 is attached to the side of the fixing plate 20. Then insert the support frame between the two support plates and place it on the lower support plate. Hold the pull plate 33 and insert the T-shaped insert 31 from the top of the third opening 30 downwards. Adjust the position of the support frame so that the limiting groove 32 is locked on both sides of a steel wire in the support frame.

[0047] This step serves to limit the movement of the support frame, preventing it from swaying on the support plate.
