Description

Technical Field

[0001] This utility model relates to the technical field of oven air duct structure, specifically an oven air duct with manually adjustable air direction and volume. Background Technology

[0002] The air outlet direction and air volume of an oven have a significant impact on temperature uniformity and efficiency. Generally, the air duct of an oven is fixed. The total air volume can be changed by changing the total air intake, but the air volume of a single air outlet is generally fixed and its air direction is also fixed. It is generally impossible to change it except by changing the location or structure of the air duct. Therefore, the ovens mentioned above do not have sufficient applicability when performing different operations and cannot change the air direction and air volume of each air outlet according to actual needs. Utility Model Content

[0003] To address the problem that the airflow direction and volume of each air outlet of the aforementioned oven cannot be adjusted according to actual conditions, this utility model provides an oven air duct that allows for manual adjustment of airflow direction and volume.

[0004] The technical solution of this utility model is as follows: A manually adjustable airflow direction and volume drying oven duct, comprising several air duct pipes installed inside the drying oven; The air duct includes a pipe body with an air cavity, and the pipe body has several air holes on its wall, and the air holes are equipped with regulators that can adjust the air direction. The regulator includes several adjusting plates arranged circumferentially around the center of the air hole; Several of the aforementioned adjusting plates are connected to the pipe wall, and the adjusting plates can be fixed to the pipe wall at any angle; A gap is provided between two adjacent adjusting plates, and the gap can be passed through the bending rod of the adjusting tool; The adjustment tool includes a long rod and a bent insert fixed to one end of the long rod.

[0005] By adjusting the angle of the adjusting plate relative to the pipe wall, the direction and volume of airflow at the air outlet can be changed. Furthermore, the adjusting plate can be fixed at any angle to the pipe wall, allowing for manual adjustment of each air outlet.

[0006] For ease of processing, the adjusting plate is integrally formed with the pipe wall, and both the adjusting plate and the pipe wall are made of flexible metal.

[0007] To facilitate bending of the adjustment plates, a clearance notch is provided at the end of each adjustment plate away from the pipe wall, and all clearance notches of all adjustment plates at the same air hole position form a clearance socket.

[0008] For easy manual adjustment, the bent insert can pass through the clearance socket.

[0009] To avoid excessive gaps affecting the adjustment effect, the gap between two adjacent adjustment plates is shortened to a point where it cannot be passed through the bending hole.

[0010] To facilitate bending of the adjusting plate, a cut hole is provided at the bending position of the adjusting plate relative to the pipe wall.

[0011] As a preferred option, four adjusting plates are arranged circumferentially at the same air vent.

[0012] To adjust the wind direction, the adjusting plate is set parallel or perpendicular to the length direction of the pipe body relative to the bending axis of the pipe wall.

[0013] To be applicable to more application scenarios, the bending axis of the adjustment plate relative to the pipe wall is at an angle of 45° with the length direction of the pipe body.

[0014] As a preferred embodiment, the pipe body is cylindrical or a regular polygon. When the pipe body is cylindrical, multiple sets of air holes are arranged around the central axis of the tank. When the pipe body is a regular polygon, at least one plane of the pipe body is not provided with air holes.

[0015] The beneficial effects of this utility model are as follows: This utility model is a manually adjustable airflow direction and air volume oven duct. Unlike conventional duct settings, the adjusting plate and the tube wall are designed to be freely adjustable in angle. In this way, the angle can be adjusted by bending with the help of an adjustment tool. Moreover, by changing the angle of different adjusting plates at the same air vent position, the air volume and airflow direction can be adjusted. Furthermore, the adjustment of the above structure is not a one-time thing, but can be performed multiple times. Therefore, it can be adjusted arbitrarily according to the needs each time it is used. By changing the position and direction of the adjusting plate, it can be applied to more application scenarios. Attached Figure Description

[0018] Example 1 like Figure 1 The oven air duct shown includes several air duct pipes 2 installed inside the oven 1. Its structure is the same as the existing oven 1 air duct installation method, so it will not be described in detail.

[0019] The key feature of this device is that the air duct 2 includes a pipe body 21 with an air cavity, and the pipe wall of the pipe body 21 is provided with a number of air holes, each of which can be used for air outlet. However, the feature is that the air hole is provided with a regulator 22 that can adjust the air direction. The air direction and air volume can be adjusted by the regulator 22. The specific method is as follows: Figure 1 , 2 As shown in Figure 3, the regulator 22 includes several adjusting plates 221 arranged circumferentially around the center of the air hole, and the adjusting plates 221 can be used to block the air hole, thereby changing its position or bending angle to change the air direction and air volume.

[0020] Specifically, several of the aforementioned adjusting plates 221 are connected to the pipe wall, and the adjusting plates 221 can be fixed to the pipe wall at any angle. In this way, the air volume and air direction can be adjusted simply by bending the adjusting plates 221 according to the requirements to change their angle. In addition, the bending of the adjusting plates 221 can be repeated, and the angle can be different each time. Furthermore, in the above structure, in order to ensure that bending can be performed normally, a gap is provided between two adjacent adjustment pieces 221, and the gap can be passed through the bending rod 32 of the adjustment tool 3. The angle adjustment can be completed simply by inserting the bending rod 32 into the corresponding gap and bending it. And such as Figure 4 As shown, the adjustment tool 3 includes a long rod 31 and a bent insert 32 fixed to one end of the long rod 31. First, the long rod 31 is convenient for operators to use, allowing them to change the state of each adjuster 22 from a distance from the oven 1. For ease of operation, a handle 33 can be provided at the end of the long rod 31 away from the bent insert 32 for easy gripping.

[0021] Furthermore, in the above structure, for ease of processing, the adjusting plate 221 is integrally formed with the pipe wall, and both the adjusting plate 221 and the pipe wall are made of flexible metal material. In this way, without external force interference, the bending of the adjusting plate 221 can be stopped at any angle by means of the material properties, and the air can be guided or blocked.

[0022] Furthermore, in the above structure, to facilitate bending of the adjusting plate 221, a clearance notch is provided at the end of each of the adjusting plates 221 away from the pipe wall, and all the clearance notches of all the adjusting plates 221 at the same air vent position form a clearance insertion hole 222, that is, as shown in the figure. Figure 2 As shown, bending can only be performed from this position to ensure that the bending direction is correct. In addition, to facilitate the determination of the installation angle, two bending rods 32 are provided at intervals along the length direction on the above-mentioned long rod 31. When the adjustment piece 221 is bent, the two bending rods 32 facilitate the control of the angle and can be easily pushed from both bending directions.

[0023] Therefore, in the above structure, in order to facilitate manual adjustment, the bending rod 32 can pass through the relief hole 222, and the long rod 31 can also pass through the relief hole 222. In this way, the bending rod 32 of the adjusting tool 3 can be placed at both ends of the adjusting piece 221 so as to adjust the bending angle in two directions in the above manner.

[0024] Furthermore, based on the above structure, in order to avoid the gap being too large and affecting the adjustment effect, the gap between two adjacent adjustment plates 221 is shortened to the point that it cannot be passed through the bending hole, thus avoiding the phenomenon of air leakage caused by the gap being too large. In this way, the air guiding effect and the air blocking effect of the above adjustment plate 221 will be better.

[0025] Furthermore, in order to reduce bending resistance and to facilitate bending of the adjusting plate 221, a cut hole 223 is provided at the relative bending position of the adjusting plate 221 and the pipe wall. The presence of the cut hole 223 can shorten the bending of the adjusting plate 221 and the pipe wall.

[0026] The above method can be used to change the air outlet direction and volume by bending the adjusting plate 221 relative to the pipe wall using the adjusting tool 3. For example, if all adjusting plates 221 are not bent, it is equivalent to the air hole being nearly blocked, allowing air to exit from the gaps and thus reducing the air volume. However, after bending, due to the change in angle, the air can be guided to the desired position, thereby adjusting the air direction. Furthermore, the adjusting plate 221 can be fixed at any angle to the pipe wall, allowing for manual adjustment of each air hole. Therefore, it is highly applicable and has the ability to be repeatedly adjusted.

[0027] Example 2 For ease of operation, in addition to the same structure as in Example 1, the following structure is also required: four adjusting plates 221 are arranged circumferentially at the same air vent. Therefore, the angle of the adjusting plate 221 at each position can be adjusted as needed.

[0028] Furthermore, for conventional needs, in order to adjust the airflow direction, the adjusting plate 221 is positioned parallel or perpendicular to the length direction of the pipe body 21 relative to the bending axis of the pipe wall. Correspondingly, to accommodate more application scenarios, the angle between the bending axis of the adjusting plate 221 relative to the pipe wall and the length direction of the pipe body 21 is 45°, such as... Figure 1 , 2 As shown, wind direction can be adjusted in virtually all locations.

[0029] And, as Figure 2 , 3 As shown, the pipe body 21 is cylindrical or regular polygonal. When the pipe body 21 is cylindrical, multiple sets of air holes are arranged around the central axis of the pipe body. When the pipe body 21 is regular polygonal, at least one plane of the pipe body 21 is not provided with air holes. Different arrangement methods can be adopted for different pipe bodies 21, but the overall method will not change.
