Description

Technical Field

[0001] This utility model relates to the field of drying ovens, specifically to the oven body. Background Technology

[0002] The oven body is the main structural part of the oven. It is usually made of metal and is used to house and protect the internal heating elements, insulation layer and items to be processed. Its design must be resistant to high temperature and corrosion and have good sealing performance to ensure uniform temperature distribution and reduce heat loss. The core function of the oven body is to provide a stable heating environment, which is suitable for drying, sterilization, curing and other processes.

[0003] Chinese patent CN218545066U discloses a novel oven body with a heat dissipation structure, including a motor. The output end of the motor is connected to a gear, and the front and rear sides of the gear are connected to toothed plates. The toothed plates are slidably connected in a limiting groove, which is located on the inner top of the oven body. When the gear meshes with the toothed plates, it drives the toothed plates to move relative to each other, allowing for simultaneous air cooling and water cooling, thereby improving the heat dissipation and cooling efficiency of the oven body. At the same time, the connecting frame drives the heating plate to reciprocate at the bottom, which can evenly dry the items, thereby improving the drying efficiency.

[0004] During use, the honeycomb trays inside the oven body are fixed in position, which means that the unused honeycomb trays will affect the heat transfer and the flow of heat generated by the heating plate at the bottom of the honeycomb tray, resulting in a temperature difference between the upper and lower ends of the honeycomb tray. Utility Model Content

[0005] The purpose of this invention is to provide an oven body in which, with the support of a bracket, the tray can be rotated within the bracket around the second connecting shaft to unfold and fold. This allows the unfolded tray to stably support the items to be processed, while the folded tray does not affect the flow of heat from the heating plate. When the items are not placed on the top of all the trays, the areas where the trays are not unfolded can efficiently allow for the flow of hot gas, ensuring that there is no temperature difference between the two ends of the lower and upper outer shells. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oven body, including an upper outer shell, with a second baffle and a first baffle respectively provided on both sides of the outer exterior of the upper outer shell. Three supports are evenly distributed laterally on both the second and first baffles, facing the center of the upper outer shell. A tray is provided on one side of the outer exterior of each support, rotatably connected to it via a second connecting shaft. An extension strip is welded to the upper outer side of the second connecting shaft, and a second locking block is provided on one side of the extension strip, rotatably connected to the second and first baffles via a third connecting shaft.

[0007] Preferably, a counterweight is welded to the lower end of the second locking block.

[0008] Preferably, a third baffle is provided at the upper end of the interior of the upper shell, and the lower end of the exterior of the third baffle is connected to the upper end of the exterior of the upper shell via a slot.

[0009] Preferably, a lower outer shell is provided at the lower end of the upper outer shell.

[0010] Preferably, a first locking block is provided at each of the four corners of the third baffle, the first baffle, and the second baffle, and the first locking block is rotatably connected to the upper housing via a first connecting shaft.

[0011] Preferably, the third baffle, the first baffle, and the second baffle are all surrounded by rubber pads on the side facing the upper outer shell.

[0012] Preferably, each of the four corners of the first and second baffles is provided with a sliding rod facing the inside of the upper housing, and the outside of the sliding rod is slidably connected to the inside of the upper housing.

[0013] Preferably, the sliding rod corresponding to the first baffle is offset from the sliding rod corresponding to the second baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The upper outer shell of this invention is wrapped on both sides by a first baffle and a second baffle, and the upper end of the upper outer shell is wrapped by a third baffle. Disassembly from multiple directions can fully expose the interior of the upper outer shell. The first and second baffles can move laterally to move the tray. The exposed folded tray can be pushed and unfolded by the user. The rotation of the tray can drive the extension strip to rotate. The second locking block can restrict the extension strip and fix the unfolded tray. Adjusting the unfolded tray can accommodate processing items of different sizes, avoiding unnecessary unfolding of the tray and preventing excess tray from affecting the heat transfer generated by the heating plate. By storing a certain amount of tray, the temperature of the lower and upper outer shells will not differ, so that the heat generated by the heating plate can be fully and efficiently distributed in the areas of the lower and upper outer shells.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] like Figure 1 As shown, the oven body of this embodiment includes an upper outer shell 2. A second baffle 4 is provided on one side of the outer shell 2, and a first baffle 3 is provided on the other side of the outer shell 2. By opening the first baffle 3 and the second baffle 4, the area inside the upper outer shell 2 can be exposed, which makes it convenient to place items inside the upper outer shell 2 and also convenient to take out the processed materials from inside the upper outer shell 2.

[0025] Among them, such as Figure 5 As shown, both the second baffle 4 and the first baffle 3 have three supports 13 evenly distributed laterally towards the middle of the upper outer shell 2. A tray 12 is provided on one side of the outside of the support 13, and the tray 12 is rotatably connected to the support 13 through the second connecting shaft 14. The position of the tray 12 can be adjusted through the connection of the second connecting shaft 14, so that the tray 12 can be unfolded or folded up.

[0026] Furthermore, an extension strip 18 is provided on one side of the upper outer end of the second connecting shaft 14, and the extension strip 18 is welded and fixed to the second connecting shaft 14. A second locking block 15 is provided on one side of the outer end of the extension strip 18. When the support plate 12 rotates, the support plate 12 will synchronously drive the extension strip 18 to rotate around the second connecting shaft 14 as the center. After the support plate 12 rotates and unfolds, the extension strip 18 will approach the second baffle 4. After the second locking block 15 covers the front end of the extension strip 18, it can restrict the rotation of the support plate 12 by restricting the extension strip 18.

[0027] In addition, such as Figure 4As shown, a counterweight 17 is provided at the lower end of the second locking block 15, and the counterweight 17 is welded and fixed to the second locking block 15. The second locking block 15 is rotatably connected to the corresponding first baffle 3 and second baffle 4 through a third connecting shaft 16. When it is necessary to rotate the tray 12 and adjust the position of the tray 12, the second locking block 15 can rotate around the third connecting shaft 16 to expose the rotation trajectory of the extension strip 18, which can prevent the extension strip 18 from rotating and colliding with the second locking block 15.

[0028] It should be noted that the weight of the counterweight 17 will cause the second locking block 15 to be actively vertical, so that the second locking block 15 can continuously restrict the extension bar 18, allowing the tray 12 to be continuously extended.

[0029] It should be noted that the support plates 12 on the sides of the second baffle 4 and the first baffle 3 can support items of different sizes. After the lower end of the supported item does not touch the support plate 12, the support plate 12 can rotate and fit against the first baffle 3 and the second baffle 4 for storage. Figure 2 As shown, the tray 12 after storage will not hinder the heat transfer generated by the heating plate 11. The lower end of the upper shell 2 is provided with a lower shell 1, so that the heat inside the lower end of the upper shell 2 will not be restricted by the tray 12 and will be quickly transferred to the lower shell 1. This allows the heat in the areas of the lower shell 1 and the upper shell 2 to be evenly distributed and prevents long-term temperature differences.

[0030] To avoid the instability of large heating materials inside the upper casing 2, such as Figure 3 As shown, a third baffle 5 is provided at the upper end of the interior of the upper shell 2, and the lower end of the exterior of the third baffle 5 is connected to the upper end of the exterior of the upper shell 2 through a slot. The upper end of the interior of the upper shell 2 can be exposed by sliding the third baffle 5 from the upper end of the upper shell 2. Exposing the upper end of the upper shell 2 makes it easy to take out and place items, and removing the third baffle 5 makes it easy to clean the interior of the upper shell 2 and the lower shell 1.

[0031] It should be noted that, in order to restrict the third baffle 5, the first baffle 3, and the second baffle 4 after they are closed, a first locking block 6 is provided at each of the four corners of the third baffle 5, the first baffle 3, and the second baffle 4. The first locking block 6 is rotatably connected to the upper shell 2 through the first connecting shaft 7. After the third baffle 5, the first baffle 3, and the second baffle 4 are in contact with the corresponding installation positions of the upper shell 2, the rotation of the first locking block 6 can be used to contact the corresponding third baffle 5, the first baffle 3, and the second baffle 4, thereby fixing the third baffle 5, the first baffle 3, and the second baffle 4.

[0032] Among them, the third baffle 5, the first baffle 3, and the second baffle 4 are all surrounded by rubber pads on the side facing the upper outer shell 2. After the rubber pads are attached to the upper ends of the third baffle 5, the first baffle 3, and the second baffle 4, they can seal the contact points between the outside of the upper outer shell 2 and the third baffle 5, the first baffle 3, and the second baffle 4 after the first locking block 6 rotates, thus preventing heat loss.

[0033] It should be noted that a viewing glass 8 is provided at one end of the upper outer shell 2, and a fan is provided at the other end of the upper outer shell 2. The fan at the rear end can cool down the interior of the upper outer shell 2 and exhaust the gas, while the viewing glass 8 can be used to observe the area inside the upper outer shell 2.

[0034] To heat the area between the lower outer shell 1 and the upper outer shell 2, a threaded rod 9 is laterally arranged at the lower end of the interior of the lower outer shell 1, and a sliding block 10 is arranged at the upper end of the exterior of the threaded rod 9. The sliding block 10 is engaged with the external thread of the threaded rod 9. The threaded rod 9 can be rotated by a motor at one end. The rotation of the threaded rod 9 can generate relative movement with the sliding block 10. The lower end of the sliding block 10 is in contact with the lower end of the interior of the lower outer shell 1. The restriction of the sliding block 10 by the lower outer shell 1 can change the sliding block 10 from rotational movement to lateral linear movement. A heating plate 11 is arranged at the upper end of the exterior of the sliding block 10 facing the support plate 12. The heating plate 11 can generate heat after being powered on. The heating plate 11 can heat the interior area of ​​the lower outer shell 1 and the upper outer shell 2.

[0035] The rotation of the sliding block 10 can adjust the position of the heating plate 11 laterally, so that the heating plate 11 can evenly heat the inner areas of the lower outer shell 1 and the upper outer shell 2.

[0036] In order to stably slide and unfold the second baffle 4 and the first baffle 3, and to facilitate the stable removal of the material placed on the side support plate 12 of the second baffle 4 and the first baffle 3, sliding rods 20 are provided at the four corners of the first baffle 3 and the second baffle 4 facing the inside of the upper outer shell 2, and the outside of the sliding rods 20 is slidably connected to the inside of the upper outer shell 2.

[0037] In addition, in order to avoid collision between the sliding rods 20 corresponding to the first baffle 3 and the second baffle 4, the sliding rod 20 corresponding to the first baffle 3 is offset from the sliding rod 20 corresponding to the second baffle 4, so as to prevent the sliding rod 20 from affecting the normal movement of the first baffle 3 and the second baffle 4.

[0038] Furthermore, to prevent the second locking block 15 from swinging due to the weight of the counterweight 17, such as... Figure 6As shown, a limiting strip 19 is provided on the side of the second locking block 15 facing the extension strip 18, and the limiting strip 19 is welded and fixed to the second locking block 15. The limiting strip 19 can restrict the swing of the second locking block 15 by fitting the extension strip 18.

[0039] Working Principle: When using the device to process items at high temperatures, for items of different shapes and sizes, the sliding rod 20 slides within the upper outer shell 2 to laterally unfold the first baffle 3 and the second baffle 4. Rotating the support plate 12 at the corresponding position of the first baffle 3 and the second baffle 4 simultaneously activates the second locking block 15. The support plate 12, the second connecting shaft 14, and the extension bar 18 rotate 90 degrees within the bracket 13 around the second connecting shaft 14, causing the support plate 12 to unfold. Stopping the activation of the second locking block 15, the second locking block 15, after being counterweighted by the counterweight block 17, rotates around the third connecting shaft 16. This rotation causes the limiting strip 19 connected to the second locking block 15 to adhere to the extension bar 18, stopping the rotation of the second locking block 15. This restricts the rotation of the second locking block 15 after unfolding. The tray 12 allows it to be unfolded and used to place items to be processed. Small items can be placed directly on the unfolded tray 12. With the restriction of the sliding rod 20, the first baffle 3 and the second baffle 4 drive the unfolded tray 12 and the items on it to be stored inside the upper outer shell 2. If larger items cannot be placed through the first baffle 3 and the second baffle 4, the third baffle 5 is taken out vertically from the upper part of the outer shell 2, directly exposing the upper part of the outer shell 2. Larger items can be placed directly from the exposed part of the third baffle 5, so that the items are placed on the unfolded tray 12. The heating plate 11 is energized and generates heat. The heat passes through the tray 12 and heats the areas of the upper outer shell 2 and the lower outer shell 1. The unfolded tray 12 does not restrict the heat transfer, so that the temperature of the areas of the upper outer shell 2 and the lower outer shell 1 does not have a large difference.
