Description

Technical Field

[0001] This utility model belongs to the field of drying oven technology, specifically an electric heating constant temperature forced air drying oven. Background Technology

[0002] The electric constant temperature forced air drying oven is a drying equipment that achieves precise temperature control through electric heating and a forced circulation hot air system. It is mainly used for drying, baking, sterilizing, and constant temperature adaptability testing of items. Forced air drying transfers heat through electric heating and forced circulation hot air (driven by a fan), and uses air convection to accelerate the evaporation of moisture on the surface of the material. The high-temperature gas directly contacts the material, thereby achieving high drying efficiency and good temperature uniformity.

[0003] When using a forced-air drying oven, the items to be dried need to be placed on each wire rack, and then the wire racks are placed inside the drying oven. After drying, the wire racks containing the dried items need to be removed from the drying chamber one by one. Since the internal temperature of the drying oven is high when drying is just completed, it is easy to burn your hands when removing the wire racks, which poses a certain danger. Therefore, this application proposes an electric heating constant temperature forced-air drying oven. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: an electric heating constant temperature forced air drying oven, comprising a box body, two sets of support plates fixedly installed on both sides of the inner wall of the box body, each set consisting of two support plates, each support plate having a groove on the side away from the inner wall of the box body, a shelf being slidably installed between the grooves on the sides of the two support plates in the same set, both shelf surfaces having neatly arranged ventilation holes, a connecting plate being fixedly connected between the center of the inner ends of the two shelf surfaces, the bottom end of the connecting plate extending to the bottom of the shelf, and a driving mechanism being provided between the bottom of the inner cavity of the box body and the bottom end of the connecting plate.

[0005] Preferably, the drive mechanism includes a screw and a motor. A screw hole is provided on the side of the bottom end of the connecting plate. The motor is fixedly installed at a lower position on the back of the housing. The screw is fixedly connected to the output end of the motor and extends through the back of the housing into its interior and is threaded into the screw hole at the bottom of the connecting plate.

[0006] Preferably, a limiting rod is fixedly installed at the top of the front end of the side panel groove of each support plate, and slots are opened on both sides of the top of the two shelves. When the shelves are slidably installed in the side panel grooves of the two support plates, the limiting rods at the top of the two panel grooves are respectively located in the slots on both sides of the top of the shelves and can slide inside them.

[0007] Preferably, each support plate has a groove at the bottom of its side panel slot, and a rotatable roller is provided in each groove, with the top of each roller extending out of the groove and abutting against the bottom of the shelf.

[0008] Preferably, a fixing block is fixedly installed at the center of the bottom of the opening end of the inner cavity of the box, and a through-hole is opened on the side of the fixing block.

[0009] Preferably, a door is hinged to the opening of the inner cavity of the box, and a control unit is provided on one side of the front of the box.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The motor drives the screw to rotate through the threaded hole at the bottom of the connecting plate, which in turn moves the screw and the two storage plates within the slot. The limiting rod inside the slot engages with the slot opening on the storage plate to prevent the storage plate from detaching from the slot. The roller at the bottom of the slot makes the storage plate movement easier. As the connecting plate moves along the direction of the screw, it gradually moves the two storage plates out of the box. This requires manual pulling out of the storage plate for drying items, improving the safety of the device during use. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-7 The present invention includes a box body 1. Two sets of support plates 4 are fixedly installed on both sides of the inner wall of the box body 1. Each set of support plates 4 consists of two plates. A groove 5 is provided on the side of each support plate 4 away from the inner wall of the box body 1. A shelf 6 is slidably installed between the grooves 5 on the sides of the two support plates 4 in the same set. The surfaces of the two shelf 6 are provided with neatly arranged ventilation holes. A connecting plate 7 is fixedly connected between the center of the inner ends of the two shelf 6. The bottom end of the connecting plate 7 extends to the bottom of the shelf 6. A driving mechanism is provided between the bottom of the inner cavity of the box body 1 and the bottom end of the connecting plate 7. By operating the driving mechanism, the connecting plate 7 and the two shelf 6 connected to it can be moved within the box body 1, thereby gradually moving the shelf 6 to move the box body 1, so that the dried items placed on the shelf 6 can be taken out.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the drive mechanism includes a screw 8 and a motor 9. A screw hole is provided on the side of the bottom end of the connecting plate 7. The motor 9 is fixedly installed at the lower position on the back of the box 1. The screw 8 is fixedly connected to the output end of the motor 9. The screw 8 extends through the back of the box 1 and into its interior and is threaded into the screw hole at the bottom of the connecting plate 7. By running the motor 9, the screw 8 and the screw hole at the bottom of the connecting plate 7 are driven to rotate threadedly. This drives the screw 8 and the two storage plates 6 to move in the plate groove 5 on the side of the support plate 4. As the connecting plate 7 moves along the direction of the screw 8, the two storage plates 6 are driven to gradually move out of the box 1.

[0025] like Figure 6 and Figure 7 As shown, each support plate 4 has a groove 14 at the bottom of its side panel groove 5. A rotatable roller 15 is provided in each groove 14. The top of each roller 15 extends out of the groove 14 and abuts against the bottom of the shelf 6. The multiple rollers 15 in the groove 14 at the bottom of the shelf 5 can prevent the bottom of the shelf 6 from contacting the bottom of the shelf 5, thereby reducing the friction between the two and making it easier for the shelf 6 to move within the shelf 5.

[0026] like Figure 3 and Figure 4 As shown, a fixing block 10 is fixedly installed at the center of the bottom of the inner cavity opening of the housing 1. An opening is provided on the side of the fixing block 10, and a bearing 11 is fixedly installed in the opening. The end of the screw 8 away from the motor 9 is fixedly connected to the inner ring wall of the bearing 11. The fixing block 10 and the bearing 11 can fix the position of the end of the screw 8, so that the screw 8 will not wobble during rotation, thus enabling the connecting plate 7 to move more stably.

[0027] like Figure 1 and Figure 3 As shown, a door 3 is hinged to the opening of the inner cavity of the box 1. A control unit 2 is provided on one side of the front of the box 1. The device can be operated through the control unit 2, so that the device can be used to dry the items on the shelf 6.
