[0002] In modern industrial production and laboratory research, electric heating ovens are key heat treatment equipment. Their temperature balance directly affects product quality, the accuracy of experimental results and production efficiency. The technical development of electric heating ovens can be traced back to the early budding of the demand for temperature control. With the advancement of power technology and the maturity of temperature control theory, electric heating ovens have gradually evolved from simple heating devices to precision equipment that integrates temperature control, ventilation circulation and safety protection.
[0003] Traditional electric heating ovens often face the problem of uneven temperature distribution, which is caused by unreasonable internal structure design of the oven, poor air circulation or improper layout of heating elements. Uneven temperature will not only lead to uneven drying of products, but may also cause material deformation, quality degradation and even safety accidents. In addition, the ventilation mechanism of existing ovens is often simply designed, lacking a scientific and reasonable air duct layout and air circulation mechanism, which leads to uneven distribution of hot air inside the oven, and the temperature in some areas is too high or too low, resulting in uneven heating of the dried objects, which in turn affects product quality.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] See also Figures 1 to 8 , an electric heating oven with temperature balance, comprising:
[0033] A shell 1, a control panel 3 is provided on one side surface of the shell 1, a display screen 6 and a control switch 7 are provided on one side surface of the control panel 3, a movable opening and closing door 4 is also provided on one side surface of the shell 1, a visual window 8 is provided at the center of the opening and closing door 4, a door handle 9 is also provided on one side surface of the opening and closing door 4, a sealing ring 38 is provided on the other side surface of the opening and closing door 4, a drying chamber is provided inside the shell 1, two air inlets 40 for internal air intake are provided on the bottom surface of the drying chamber, an air induction ramp 41 is provided between the two air inlets 40, a hot air blower matched with the air inlet 40 is also provided inside the shell 1, and an air outlet 2 matched with the air inlet 40 is provided on the upper surface of the shell 1;
[0034] When in use, the staff pulls the door handle 9 to open the opening and closing door 4, and puts the objects to be dried into the drying chamber inside the housing 1, and then adjusts the internal temperature by operating the control panel 3. The drying time and temperature can be observed through the display screen 6 on the surface of the control panel 3, and the visual window 8 at the center of the opening and closing door 4 can be used to observe the drying state of the internal drying objects;
[0035] A placing mechanism is provided inside the housing 1, and the placing mechanism is used to place the dried items during drying. The placing mechanism includes: two side panels 13, a plurality of placing racks 19 are provided between the two side panels 13, and the plurality of placing racks 19 are arranged vertically. A ventilation plate 14 is provided at the center of the placing rack 19, a roller 21 is provided on the bottom surface of the side panel 13, and a handle 15 is provided on one side surface of the side panel 13. An extension plate 5 is also connected to one side surface of the housing 1 through a shaft 39, and a slide groove 10 matching the roller 21 is provided on the upper surface of the extension plate 5, and a pull ring is provided on one side surface of the extension plate 5;
[0036] When in use, the staff pulls the handle 15 to make the two side panels 13 roll through the rollers 21 on the bottom, driving the placement rack 19 to move outward and move to the top of the extension plate 5 through the slide groove 10, so as to facilitate the loading of the surface of the placement rack 19. After the staff places the drying objects on the surface of the placement rack 19, the staff can pull the pull ring to make the extension plate 5 bend downward through the shaft 39, and then after closing the opening and closing door 4, the internal drying process can be started by operating the control panel 3;
[0037] The above process is the basic process of using the drying oven at present.
[0038] However, in actual use, when the air inlet 40 sends hot air into the interior of the housing 1 to dry the dried objects and the hot air is discharged from the interior of the housing 1 through the air outlet 2, because the ventilation plates 14 have multiple layers and are vertically discharged, during the hot air passing through, the hot air is blocked by the multiple layers of ventilation plates 14, and the passing speed is limited. When the surface of the ventilation plates 14 is full of dried objects, the openings on the surface of the ventilation plates 14 are also blocked, further affecting the efficiency of the hot air passing through, thereby causing a temperature difference inside.
[0039] In addition, during the internal drying process, because the drying object is placed on the upper surface of the ventilation plate 14, and the bottom surface of the ventilation plate 14 is in direct contact with the hot air, during drying, the hot air blows to the bottom surface of the object through the openings on the surface of the ventilation plate 14, but the top surface of the object is blocked by the ventilation plate 14 and the object itself, resulting in a difference in the drying efficiency of the bottom surface and the top surface, resulting in a difference in the drying progress on both sides, and when the dried object is taken out, because the temperature inside is high, there is a certain risk when taking out the object;
[0040] Therefore, based on the above problem, we first design a ventilation mechanism, which includes: a meshing ring 20, which is sleeved on the surface of the placement rack 19, and each placement rack 19 is provided with a meshing ring 20 on its surface, and can slide on the surface of the placement rack 19, and the placement rack 19 and the meshing ring 20 are provided with air ducts on both sides of the center, and the two air ducts are respectively located directly above the two air inlets 40;
[0041] Air ducts are opened on both sides of the center of the meshing ring 20 and the placement rack 19. The two air ducts are directly aligned with the two air inlets 40 at the bottom of the shell 1, ensuring that the hot air entering from the air inlet 40 can directly and efficiently pass through the placement rack 19 from the bottom to the air outlet 2 on the top surface, reducing the restriction of the multi-layer ventilation plate 14 on the hot air flow rate, achieving the characteristic of faster hot air flow and faster internal temperature transfer.
[0042] At the same time, based on the previous problems, we have also designed an air induction mechanism, which includes: four fan plates 18 for driving wind to accelerate, the four fan plates 18 are located on the inner side of the meshing ring 20, and the inside of the side plate 13 is provided with a driving gear plate 23 for driving the meshing ring 20 at the bottom layer to rotate, and a connecting frame 22 is provided on the upper surface of the driving gear plate 23, and the connecting frame 22 is fixedly connected to the inner side surface of the side plate 13, and a main bevel gear 25 is provided on the bottom surface of the driving gear plate 23, and a secondary bevel gear 26 meshing with the main bevel gear 25 is provided on the bottom surface of the main bevel gear 25, and a secondary bevel gear 26 meshing with the main bevel gear 25 is provided on the bottom surface, and one side of the secondary bevel gear 26 is fixedly connected to the inner side surface of the side plate 13 through a connecting rod, and a main transmission shaft is provided on the other side surface of the secondary bevel gear 26, and a first transmission belt 27 is provided on the surface of the transmission shaft, and two main rotating rods 28 are provided on the bottom surface of the main bevel gear 25, and a secondary transmission shaft is provided between the two main rotating rods 28. The bottom surface of the first transmission belt 27 is sleeved on the surface of the secondary transmission shaft. A fixing frame 24 is provided on one side of the two main rotating rods 28. One side surface of the fixing frame 24 is fixedly connected to the inner side surface of the side plate 13. One side surface of the main rotating rod 28 is provided with two secondary rotating rods 29 corresponding to the main rotating rod 28. The main rotating rod 28 and the secondary rotating rod 29 are connected by a second transmission belt 32. A fan blade 30 is provided on one side surface of the secondary rotating rod 29. The fan blade 30 is located at the center of the air duct. A mounting bracket 31 is provided between the two secondary rotating rods 29. One side surface of the mounting bracket 31 is fixedly connected to the inner side surface of the side plate 13. An anchor plate 34 is fixedly installed on the inner bottom surface of the shell 1. The upper surface of the anchor plate 34 is fixedly installed on the rotating rod 17. The surface of the rotating rod 17 is sleeved with a plurality of mating meshing disks 33, and the mating meshing disks 33 mesh with the meshing ring 20.
[0043] The driving toothed disc 23 inside the side plate 13 drives the bottom meshing ring 20 to rotate. When in use, the fan blades 30 are driven to rotate when the hot air passes through the air duct. As the fan blades 30 rotate, the auxiliary rotating rod 29 on the side surface of the fan blades 30 rotates synchronously, and transmits kinetic energy to the main rotating rod 28 through the second transmission belt 32. During the rotation of the main rotating rod 28, the auxiliary transmission shaft between the two main rotating rods 28 transmits kinetic energy to the upper main transmission shaft through the first transmission belt 27. As the main transmission shaft rotates, the auxiliary bevel gear 26 is driven to rotate synchronously, and the driving toothed disc 23 is driven to rotate through the meshing of the auxiliary bevel gear 26 and the main bevel gear 25. When the driving toothed disc 23 rotates, the meshing effect of the driving toothed disc 23 and the meshing ring 20 drives the meshing ring 20 to rotate. Because the rotating rod 17 is provided inside the shell 1, A plurality of mating engagement disks 33 are provided on the surface of the rotating rod 17. Through the meshing effect of the mating engagement disk 33 at the bottom layer and the meshing ring 20, the meshing ring 20 drives the rotating rod 17 to rotate when it rotates, and drives other meshing rings 20 above to rotate synchronously through the plurality of mating engagement disks 33 on the surface of the rotating rod 17. The four fan plates 18 are located on the inner side of the meshing ring 20. The wind force generated by the rotation guides the hot air circulating through the air duct to the top of the drying object, and through the rotation of the meshing ring 20 and the four fan plates 18, the hot air is accelerated to rotate above the ventilation plate 14, so that the surface of the drying object is subjected to a stronger drying effect, and the rotating hot air passes through the upper ventilation plate 14. Because the rotating hot air is accelerated, the efficiency of the hot air passing through the ventilation plate 14 is improved, and the problem of uneven drying caused by the obstruction of the ventilation plate 14 is reduced.
[0044] Based on the above problems, we have also designed a fixing mechanism, which includes: an exposure groove 12 is also provided on one side surface of the side panel 13, a pull handle 15 is located inside the exposure groove 12, a matching opening 11 matching with the exposure groove 12 is provided at the center of the opening and closing door 4, two gripping handles 37 are also provided on one side surface of the side panel 13, two sliding blocks 35 are provided on both sides of the gripping handle 37, a square plug hole matching with the sliding block 35 is provided on the inner side surface of the 1, a sliding groove 16 matching with the sliding block 35 is provided on the side surface of the side panel 13, and a sliding sheet 36 sliding inside the sliding groove 16 is provided on the upper and lower surfaces of the sliding block 35;
[0045] The exposed groove 12 on the side panel 13 cooperates with the matching opening 11 on the opening and closing door 4, so that when the opening and closing door 4 is closed, the handle 15 is exposed to the outside of the drying chamber, so that after the drying process is completed, there will be no hidden danger of burns when the staff pulls the handle 15 to pull out the placement mechanism. The sliding blocks 35 on both sides of the gripping handle 37 slide in the sliding groove 16 of the side panel 13 through the sliding sheet 36, and when placed in the drying chamber, they cooperate with the square socket to achieve a stable installation of the placement mechanism, thereby ensuring the stability of the placement mechanism.
[0046] The working principle of the present invention application is:
[0047] When in use, the staff pulls the door handle 9 to open the opening and closing door 4, and the staff pulls the handle 15 to make the two side panels 13 roll through the rollers 21 on the bottom surface, driving the placement rack 19 to move outward, and move to the top of the extension plate 5 through the slide groove 10, so as to facilitate the loading of the surface of the placement rack 19;
[0048] After the staff puts the dried objects on the surface of the placement rack 19, because the exposed groove 12 on the side plate 13 cooperates with the matching opening 11 on the opening and closing door 4, when the opening and closing door 4 is closed, the pull handle 15 is exposed to the outside of the drying chamber, so that after the drying process is completed, there is no hidden danger of scalding when the staff pulls the pull handle 15 to pull the placement mechanism out, and the sliding plug blocks 35 on both sides of the gripping handle 37 slide in the sliding grooves 16 of the side plate 13 through the sliding sheet 36, and when placed in the drying chamber, they cooperate with the square plug hole to achieve a stable installation of the placement mechanism, ensuring the stability of the placement mechanism. The staff can pull the pull ring to make the extension plate 5 bend downward through the shaft body 39, and then after closing the opening and closing door 4, the internal drying process can be started by operating the control panel 3, and then the internal temperature can be adjusted by operating the control panel 3. The drying time and temperature can be observed through the display screen 6 on the surface of the control panel 3, and the visual window 8 at the center of the opening and closing door 4 can observe the drying state of the dried objects inside;
[0049] During the drying process, because the meshing ring 20 and the two sides of the center of the placement rack 19 are provided with air ducts, the two air ducts are directly aligned with the two air inlets 40 at the bottom of the shell 1, ensuring that the hot air entering from the air inlet 40 can directly and efficiently pass through the placement rack 19 from the bottom to the air outlet 2 on the top surface, reducing the restriction of the multi-layer ventilation plate 14 on the hot air flow rate, achieving the characteristic of faster hot air flow, and making the internal temperature transfer faster;
[0050] When in use, the fan blades 30 are driven to rotate when the hot air passes through the air duct. As the fan blades 30 rotate, the auxiliary rotating rods 29 on the side surfaces of the fan blades 30 rotate synchronously, and the driving toothed disc 23 is driven to rotate through the meshing of the auxiliary bevel teeth 26 and the main bevel teeth 25. When the driving toothed disc 23 rotates, the meshing effect of the driving toothed disc 23 and the meshing ring 20 drives the bottom meshing ring 20 to rotate. Because the housing 1 is provided with a rotating rod 17 inside, and the surface of the rotating rod 17 is provided with a plurality of mating meshing discs 33, the meshing effect of the bottom mating meshing disc 33 and the meshing ring 20 makes the meshing ring 20 drive the rotating rod 17 to rotate when it rotates. The meshing ring 20 is moved, and the other meshing rings 20 above are driven to rotate synchronously through the multiple mating discs 33 on the surface of the rotating rod 17. The four fan plates 18 are located on the inner side of the meshing ring 20. The wind force generated by the rotation guides the hot air circulating in the air duct to the top of the drying object. The meshing ring 20 and the four fan plates 18 rotate, so that the hot air is accelerated above the ventilation plate 14, so that the surface of the drying object is subjected to a stronger drying effect, and the rotating hot air passes through the upper ventilation plate 14. Because the rotating hot air is accelerated, the efficiency of the hot air passing through the ventilation plate 14 is improved, and the problem of uneven drying caused by the obstruction of the ventilation plate 14 is reduced.
