[0030] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0031] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0032] As described in the background technology, in order to expand the internal storage area, the existing oven usually has multiple layers of storage plates placed inside. However, since the internal heating device is fixed and the internal air is not circulated, it is easy to cause uneven internal heating and affect the quality of material drying.

[0033] For the reasons stated above, please refer to the attached Figure 1 The utility model provides a uniformly heated oven, comprising a box body 1, a side opening and a door 2 arranged at the opening;

[0034] The partition plate 3 is arranged on both sides of the interior of the box body 1 to divide the interior of the box body 1 into an air supply area and a placement area;

[0035] By the attached Figure 4 It can be seen that the area between the two partitions is the placement area, and the area inside the partition and the box is the air supply area.

[0036] The support frame 5 is movably placed in the placement area and kept horizontally placed;

[0037] The air supply pipe 6 is arranged at the top of the box body 1 and keeps the air outlet above the air supply area;

[0038] The heating device 8 is arranged in the air supply area near the air supply pipe 6;

[0039] The partition plate 3 is evenly provided with connecting holes 10 for connecting the air supply area and the placement area. The inner side of the box body 1 is also provided with a guide plate 7 for guiding the air inside the air supply area to the placement area.

[0040] Specifically, there are two partition plates 3, which are vertically arranged on the inner side of the box body 1 respectively. Corresponding support blocks 9 are arranged on the opposite ends of the partition plates 3, and support plates 4 are installed on the support blocks 9. The support frame 5 is horizontally placed on the support plates 4 at the opposite ends of the two partition plates 3.

[0041] Through the above-mentioned technical features, two partition plates are provided to form a placement area between the partition plates, thereby facilitating the installation of the support frame. At the same time, an air supply area is formed between the outer end of the partition plate and the box body to facilitate air supply and drying of the layered support frames to ensure uniform drying.

[0042] Specifically, the support block 9 is in the shape of a stepped shaft, with its small end in contact with and fixed to the partition plate 3 and its large end facing outward. The support block 9 corresponds to the position of the connecting hole 10 of the partition plate 3 and a matching through hole is opened on the support block 9.

[0043] Specifically, the cross-section of the support plate 4 is L-shaped, and a slot is provided on one end thereof. The support plate 4 is clamped on the small end of the support block 9 through the slot and is fixed in position through the large end.

[0044] Through the above technical features, the shapes of the support blocks and support plates are set to facilitate quick installation and fixing of the support plates on the support blocks, and also to facilitate removal, and to facilitate adjustment of the height according to the material, thereby facilitating the placement of multi-layer support frames.

[0045] Specifically, the air supply pipe 6 is ring-shaped, one end of which is connected to the external pipe through a connecting pipe, and the other end is placed above the partition plate 3. An air outlet is opened at the bottom of the air supply pipe 6 at a position corresponding to the air supply area.

[0046] Through the above technical features, the shape of the air supply pipe is not only convenient for installation, but also convenient for exhausting air to the two air supply areas, thereby accelerating the internal air flow for drying.

[0047] Specifically, an exhaust port is provided at a position on the bottom of the box body 1 corresponding to the placement area.

[0048] Through the above technical features, the exhaust vents and position at the bottom of the box are set to facilitate the exhaust of internal air and achieve uniform drying inside.

[0049] Specifically, the support frame 5 is in the shape of a mesh plate.

[0050] Through the above technical features, setting the support frame in a mesh shape makes it easier for multiple layers of support frames to be connected to each other, so as to facilitate the flow of air.

[0051] When the oven is in use, the installation position of the support plate 4 is adjusted according to the height of the material to facilitate the placement of multiple layers of material. The installation and removal of the support plate 4 can be achieved by simply combining and separating the card slot at the bottom with the support block 9. Figure 6 It can be seen carefully that the installation process will not be repeated here.

[0052] After the installation is completed, the support frame 5 is placed on the support plate 4, and then the materials are evenly placed on the support frame. After closing the box door 2, the drying can be carried out. During drying, the heating device 8 (such as an electric heating tube) is first started, and then the external air is transported to the inside through the air supply pipe 6 for flow. When it flows to the heating device 8, it is heated, and then the heated air continues to flow downward. Under the action of the guide plate 7, a part of the heated air passes through the connecting hole 10 of the partition plate 3 and enters the placement area to heat and dry the material, while the other part of the heated air continues to flow downward, and enters the placement area from the connecting hole 10 at the lower end under the guiding action of the guide plate 7 of the lower layer, thereby realizing the heating of the material placed on the bottom layer.

[0053] To further achieve uniform drying temperature, please refer to the following

[0054] In order to facilitate the description of the uniform drying process, the temperature of the drying air is divided into primary temperature (the highest temperature when the air comes into contact with the heating device), secondary temperature, tertiary temperature, etc.

[0055] In the process of heating and drying the materials, since the heating device 8 is installed on the partition plate 3 near the air supply pipe 6, when the air is discharged from the air supply pipe 6, it is heated by the heating device 8, and then flows downward to the first guide plate 7, a part of the heated air (referred to as air A, which has the highest temperature at this time, the first-level temperature) passes through the connecting hole 10 and contacts the materials on the upper support frame 5, and is heated and dried. At this time, the drying temperature is relatively high, and since this part of the air has been in contact with the materials on the upper support frame 5 for heat exchange, there will be a part of heat loss (from the first-level temperature to the second-level temperature). Since the exhaust hole is provided at the bottom of the placement area, the air A will pass through the support frame 5 and flow downward, which is convenient for drying the lower material. When air A reaches the lower layer of materials, another part of the heated air (referred to as air B) flowing in its air supply area also passes through the connecting hole 10 under the action of the lower layer guide plate 7 to reach the corresponding layer of materials. Since air B loses heat in the process of flowing downward (as it is farther and farther away from the heating device), the temperature may drop to the secondary temperature. However, due to the combination with air A (at this time, the secondary temperature), the heat will be increased, and it will be restored to the primary temperature, thereby achieving drying of the lower layer of materials. After drying, air A and air B continue to flow downward (at this time, due to heat exchange, the temperature may drop to the secondary temperature again, but the gas volume is larger), and then the lower layer of materials can be dried. The above steps can achieve uniform drying.

[0056] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
